PRELIMINARY PROSPECTUS

YIELD10 BIOSCIENCE, INC.

2,777,777 Class A Units consisting of one share of common stock, one Series A Warrant and one Series B Warrant, and 4,000 Class B Units consisting of one share of Series A Preferred Stock, one Series A Warrant and one Series B Warrant (and 38,879,554 shares of common stock underlying shares of Series A Preferred Stock, Series A Warrants and Series B Warrants)

We are offering Class A Units (the “Class A Units”), with each Class A Unit consisting of one share of common stock, par value $0.01 per share (the “common stock”) and accompanying Series A Warrants (the “Series A Warrants”) and Series B Warrants (the “Series B Warrants”) at an assumed public offering price of $0.36 per Class A Unit. Each Series A Warrant and Series B Warrant included in the Class A Units entitles its holder to purchase one share of common stock. The Series A Warrants included in the Class A Units will be exercisable for an aggregate of 2,777,777 shares of common stock and the Series B Warrants included in the Class A Units will be exercisable for an aggregate of 2,777,777 shares of common stock.

We are also offering to those purchasers whose purchase of our Class A Units in this offering would result in the purchaser, together with its affiliates and certain related parties, beneficially owning more than 4.99% (or, at the election of the purchaser, 9.99%) of our outstanding common stock following the consummation of this offering, the opportunity to purchase, if they so choose, in lieu of the number of Class A Units that would result in ownership in excess of 4.99% (or, at the election of the purchaser, 9.99%), Class B Units. Each Class B Unit will consist of one share of our Series A Preferred Stock, par value $0.01 per share (the “Series A Preferred Stock”) convertible into 2,777 shares of common stock, Series A Warrants to purchase 2,777 shares of common stock and Series B Warrants to purchase 2,777 shares of common stock (together with the shares of common stock underlying such shares of Series A Preferred Stock, such Series A Warrants and such Series B Warrants, the “Class B Units” and, together with the Class A Units, the “Units”) at a public offering price of $1,000 per Class B Unit. Each Series A Warrant and Series B Warrant included in the Class B Units entitles its holder to purchase a number of shares equal to 100% of the common stock underlying each share of Series A Preferred Stock. Based on an assumed conversion price of our common stock of $0.36 per share, the Series A Preferred Stock included in the Class B Units will be convertible into an aggregate total of 11,108,000 shares of common stock, the Series A Warrants included in the Class B Units will be exercisable for an aggregate total of 11,108,000 shares of common stock and the Series B Warrants included in the Class B Units will be exercisable for an aggregate total of 11,108,000 shares of common stock.

The Class A Units and the Class B Units have no stand-alone rights and will not be certificated or issued as stand-alone securities. The shares of common stock, Series A Preferred Stock and warrants comprising the units are immediately separable and will be issued separately in this offering.

authorized shares at a stockholder meeting to be called for that purpose. Mr. Schuler and entities related to him have signed voting agreements committing to vote in favor of such amendment. While we have agreed to the terms of the concurrent private placement with Mr. Schuler, we cannot assure you that the concurrent private placement will be completed.

The underwriters have the option to purchase additional shares of common stock and/or Series A Warrants to purchase shares of common stock and/or Series B Warrants to purchase shares of common stock to cover over-allotments, if any, at the price to the public less the underwriting discounts and commissions. The over-allotment option may be used to purchase shares of common stock, Series A Warrants or Series B Warrants, or any combination thereof, as determined by the underwriters, but such purchases cannot exceed an aggregate of 15% of the number of shares of common stock (including the number of shares of common stock issuable upon conversion of shares of Series A Preferred Stock) and Series A Warrants and Series B Warrants sold in the offering. The over-allotment option is exercisable for 45 days from the date of this prospectus.

We do not currently have a sufficient number of authorized shares of common stock to cover the shares issuable upon exercise of the warrants being offered by this prospectus. As a result, before any warrants can become exercisable, we will seek stockholder approval of an amendment to our certificate of incorporation to implement an increase in the number of authorized shares of our common stock (the “Charter Amendment”) at a special meeting of stockholders to be called for this purpose. Further, the Series B Preferred Stock and warrants that are being sold in the concurrent private placement will not be convertible into shares of common stock until the approval of the Charter Amendment. While our board of directors will unanimously recommend that stockholders approve the Charter Amendment, we cannot assure you that we will be able to obtain the requisite stockholder approval of the Charter Amendment. The warrants will be exercisable on any day on or after the date on which we publicly announce, through filing of a Current Report on Form 8-K, that we have sufficient authorized shares of common stock as a result of the Charter Amendment. The Series B Preferred Stock will automatically convert into common stock on the date of the public announcement described in the preceding sentence. The Series A Warrants included in the Units will expire two and one half years from the date of issuance and the Series B Warrants included in the Units will expire seven and one half years from the date of issuance.

Our common stock is listed on The Nasdaq Capital Market under the symbol “YTEN.” On November 4, 2019, the last reported sale price for our common stock was $0.36 per share. All share and warrant numbers of the securities being offered included in this prospectus are based on an assumed public offering price per share of $0.36 and an assumed conversion price of $0.36 per share. The recent market price used throughout this prospectus may not be indicative of the final offering price. The final public offering price will be determined through negotiation between us and the underwriter based upon a number of factors, including our history and our prospects, the industry in which we operate, our past and a present operating results, the previous experience of our executive officers and the general condition of the securities markets at the time of this offering. We do not intend to apply for listing of the warrants or the shares of Series A Preferred Stock offered hereby on any securities exchange or trading system.

PROSPECTUS SUMMARY

This summary highlights some information from this prospectus. It may not contain all the information important to making an investment decision. You should read the following summary together with the more detailed information regarding our Company and the securities being sold in this offering, including “Risk Factors” and other information incorporated by reference herein.

Business Overview

Yield10 Bioscience, Inc. is an agricultural bioscience company which uses its "Trait Factory" to develop high value seed traits for the agriculture and food industries. Specifically, Yield10 plans to efficiently develop superior gene traits for the major grain crops, including corn, soybean, canola, wheat and rice that will enable step-change increases in crop yield of at least 10-20 percent. While maintaining our focus on the development of novel yield traits for grain crops based on a licensing model, we have recently begun to execute the second part of our strategy which is to develop independent business opportunities for Yield10 in the specialty oils and niche crop space using the oilseed Camelina. The target of this effort is sustainable business solutions to support agriculture, global food production and other specialty applications. Yield10 brings a unique history, skill set and tools, captured in our Gene Ranking Artificial Intelligence Network ("GRAIN") platform for developing advanced crop traits and increasing the concentration of specific biochemicals of commercial interest in crops. Our plan is to develop a source of revenue from funded research and development collaborations for traits, products and crops not being directly pursued internally. The Company is currently engaged in a range of discussions with third parties with respect to different crops, traits and products in the feed, food and pharmaceutical sectors. Yield10 Bioscience is headquartered in Woburn, Massachusetts and has an oilseed development Center of Excellence in Saskatoon, Saskatchewan, Canada.

We are currently progressing several novel yield gene traits in our pipeline in the major North American row crops canola, soybean and corn, and the niche crop Camelina, among others. Camelina is an oilseed crop similar to canola, with significant upside potential as a source of edible oils and polyhydroxyalkanoate ("PHA") biomaterials. Our approach is to focus internal resources on progressing our traits through development and field trials in Camelina and canola while leveraging third party resources to progress our traits in soybean and corn while retaining control of our intellectual property. Over the last three years, we have evaluated certain of our traits in greenhouse studies and field tests conducted in the United States and Canada. We currently have non-exclusive research license agreements in place with the Crop Science division of Bayer AG, for the evaluation of our C3003 and C3004 traits in soybean and with Forage Genetics International, LLC, a division of Land O’Lakes, Inc. for the evaluation of five yield traits in forage sorghum. Our business strategy is to progress our traits into field tests to generate validating yield data. We have progressed our evaluation of C3003 in field tests with Camelina and canola and we are planning to expand our field tests with more C3003 canola events as well as additional traits in Camelina, canola and corn in 2019 and 2020. We plan to leverage data that we generate to support the performance of our traits in key crops to establish collaborations or to sign licenses to the traits with major agricultural companies in order to generate revenue.

According to a United Nations report, crop production must be increased by over 70 percent in the next 35 years to feed the growing global population, which is expected to increase from 7 billion to more than 9.6 billion by 2050. During that time period, there will be a reduction in available arable land as a result of infrastructure growth and increased pressure on scarce water resources. Consumption of meat, fish, and dairy products is also expected to increase based on dietary changes associated with increasing wealth and living standards. Harvestable food production per acre and per growing season must be increased to meet this demand. At the same time, with the increasing focus on health and wellness, food safety and sustainability in developed countries, we anticipate a rise in demand for new varieties of food and food ingredients with improved nutritional properties. With crop intensification (less land available and more production needed), we expect that improved crop genetics based on new gene traits will be a key driver of increased productivity, potentially resulting in the best performing yield traits commanding disproportionate value and disrupting the seed sector. We expect farmers and growers to be the major beneficiaries of these drivers, which represent potential opportunities for increased revenue and crop diversification. Today the global food market has an estimated value of $5 trillion.

Exciting new genetic engineering technologies like the CRISPR technology and other approaches to genome editing hold promise to accelerate the deployment of novel traits into commercial crops. This method of making insertions or deletions of DNA into plants without the use of foreign DNA has been described as “precision breeding.” We signed a research license, with rights to convert to a commercial license, to CRISPR/Cas-9 technology in 2018 to support our genome editing program. We have taken two genome edited traits designed to boost oil content in oilseed crops through the U.S. Department of Agriculture ("USDA")—Animal and Plant Health Inspection Service ("APHIS") “Am I Regulated?” petitioning process and confirmed that the agency does not consider two of our lines to be regulated pursuant to 7 CFR part 340, clearing the way to conduct field tests in the United States. Genome editing technology as well as the streamlined regulatory process supported by USDA-APHIS for certain types of plant traits may enable agricultural innovators such as Yield10 to deploy and field test new traits more quickly, potentially resulting in a shorter path to market and reduced costs as compared to the more highly regulated path required for traditional biotechnology-derived traits.

Founded in 1992 as Metabolix, Inc., the Company was previously focused on redirecting carbon flow in living systems to produce bioplastics and biobased chemicals. In 1997, Metabolix started a crop science research program with the intent to produce polyhydroxybutyrate (“PHB”), a natural biomaterial produced in crops such as Camelina. The PHB biomaterial, which is chemically the simplest member of the PHA family, is potentially useful as a natural water treatment product and as a replacement for petroleum-based plastics. As we made progress on our crop program, we learned that the rate of carbon supply from photosynthesis was a bottleneck to the effective utilization of carbon, and we initiated a series of exploratory programs to develop new technologies to fundamentally increase the plants’ ability to fix and capture more carbon. These early research programs resulted in the establishment of our crop yield trait gene discovery platforms and the identification of a series of promising proprietary yield trait genes, even as the PHB biomaterial produced in Camelina remained interesting.

Based on challenges in the industrial biotechnology space and encouraging early results from these gene discovery programs, we refocused our crop science efforts to yield improvement in major food and feed crops in 2015 and rebranded the effort as Yield10 Bioscience (Yield10: increasing soybean and canola yields by 10 bushels per acre in North America could generate around $10 billion in added value). In 2016, we sold our fermentation based biopolymers assets. In January 2017, we completed this transition and changed the name of the company to Yield10 Bioscience, Inc. Today, we are developing proprietary, breakthrough plant biotechnologies to improve crop productivity and seed yield in commercial crops for licensing to the major agricultural companies as well as new business opportunities focused on niche crop products based on our GRAIN proprietary discovery platform. The GRAIN platform is not only an important part of Yield10's discovery and development capabilities but has the potential to be leveraged as a source of near-term revenue.

Yield10 has a pipeline of more than 10 novel yield traits in research and development and we expect to generate several proof points for our traits in various crops over the next two years. We are developing our lead yield trait C3003 in canola and recently completed the second year of field tests of C3003 in Canada. Field tests are continuing in 2019 as we advance the trait towards commercial development by developing additional commercial canola lines (events) with the trait and expanding field testing. We are conducting our first field testing of C3004 in our Camelina platform in 2019 and are currently working to deploy and test this promising trait in canola and soybean, as well as in corn in the future. We have proven capabilities with genome editing using the CRISPR/Cas9 system and have been granted “non-regulated” status from USDA-APHIS for single and multiple genome edited lines of Camelina designed to increase oil content. In 2019, we are field testing these plant lines and plan to use the data to optimize the deployment of these traits to boost oil content in canola and potentially soybean. We recently successfully edited C3007, a novel target gene for increasing oil content, in canola and these plants are now progressing through our development pipeline. We are progressing initial development and testing of multiple traits in wheat and rice as a means to attract funded partnerships for these crops. Our approach is to engineer rice and wheat plants with our gene regulator traits to increase photosynthesis and grain yield and use those plants as a source of data to generate new gene targets for genome editing. Yield10 has no plans to field test or develop wheat or rice using traditional genetic engineering technologies. We anticipate that data generated on our traits will enable us to establish revenue generating collaborations in the future for the development and commercialization of our novel yield traits in commercial crops.

We are building a portfolio of intellectual property around our crop technologies and traits. As of September 30, 2019, we owned or held exclusive rights to 23 pending patent applications worldwide related to advanced technologies for increasing yield in crops and for increasing the oil content in oilseed crops. In June 2019, we filed a new patent on what we believe to be a breakthrough technology for sustainable low-cost production of PHB biomaterials in engineered oilseeds such as Camelina. Our portfolio of patent applications includes plant science technologies we have in-licensed globally and exclusively from the University of Massachusetts and North Carolina State University related to the yield trait gene C3003 and other advanced technologies based on advanced metabolic engineering methods to improve carbon capture and selectively control carbon partitioning in plants. Our portfolio of patent applications also includes advanced technologies for increasing oil content in oilseed crops such as Camelina and canola that we in-licensed globally and exclusively from the University of Missouri in 2018 and 2019 related to the yield trait genes C3007, C3010 and C3012.

One of the critical unmet needs in the agricultural sector is to increase the fundamental yield potential of crops to address global food security. This challenge is well suited to Yield10's unique background and expertise in metabolic modeling, genetic engineering, genome editing and next generation microbial gene systems which collectively form the foundation of Yield10's trait development process. We refer to this trait development process as the "Trait Factory." The Trait Factory encompasses discovery gene targets using our GRAIN platform, genetic engineering of crops using traditional approaches or genome editing to modify those targets, and generation of field data with the engineered crops. Performance and molecular data from the engineered crops are then fed back into the GRAIN system to enable refinement of specific gene targets and the identification of new trait gene targets. Modified crops with improved performance enter the development pipeline and progress on the regulated or non-regulated path to market depending on how the plants are genetically engineered. GRAIN is a powerful new tool developed primarily to focus on Yield10 trait targets including performance traits for major row crops including, corn, soybean, and canola as well as our niche product opportunities based on our Camelina platform. We believe we may also be able to generate additional revenue streams by providing access to our GRAIN platform for third parties interested in other trait targets and/or crops Yield10 is not pursuing.

Business Strategy

Our goal is to build a successful agricultural biotechnology company centered on demonstrating and capturing the value of our traits and technologies based on three potential revenue streams in major food and feed crops for licensing to established agricultural companies and building other revenue generating business from our new niche crop opportunities we have begun developing based on our patent protected technologies. These potential revenue streams consist of:


•	Licensing of our yield and performance traits for use in major row crops;


•	Product sales revenue from niche products produced in our Camelina platform and other oilseeds; and


•	R&D revenue for access to our GRAIN trait gene discovery platform.

We have identified and are evaluating novel yield trait genes in our Trait Factory to help address the growing global yield gap in food and feed crops. As the primary driver of financial returns each season, crop yield is the key decision variable for farmers in making seed buying decisions, and as a result is critical to the seed industry. Improvements in yield to the levels targeted by Yield10, for example 10-20 percent increases, would be expected to generate significant value to the seed and crop industry. For example, Yield10 is targeting an approximately 10-20 percent increase in canola and soybean yields, which, if successfully deployed across North American acreage, could result in annual incremental crop value of up to $10 billion. By ultimately increasing the output of major food and feed crops and potentially reducing strains on scarce natural resources, we believe that Yield10’s technologies will also contribute to addressing global food security.

develop yield traits that enable farmers to increase their revenue and secure a share of that added value. To do this Yield10 plans to license its trait innovations to the major agricultural companies so that they can be deployed in elite seed varieties. The licensing - incremental value sharing model is well established in the seed sector so we intend to seek industry collaborations and partnerships with the current seed industry participants.

Yield10 will focus on its core competency, which is breakthrough science and technology innovation directed at the development of performance traits for the seed sector and new niche product opportunities such as nutritional oils and PHA biomaterials utilizing our Camelina platform. One goal of our niche crop products is to enable a clear path to product based sales and revenue to complement our licensing strategy for major crops. Here we plan to take advantage of the progress we have made using our Camelina Fast Field Testing platform for identifying and validating yield and oil content traits for major row crops and our recent breakthrough technology for low cost PHA biomaterial production, which have a wide range of potential applications and markets including water treatment and replacements for petroleum plastics.

Risks Affecting Us

Our business is subject to a number of risks and uncertainties that you should understand before making an investment decision. For example, we have a history of net losses and our commercial products may not achieve commercial success. Furthermore, our technologies are in the early stages of development and we may never commercialize a technology or product that will generate meaningful, or any, revenues. A portion of our revenue to date has been from government grants. Over time, we expect our revenue to shift from being derived primarily from collaborations and government grants to royalties based on licensing of Yield10 traits and/or sales derived from niche crop products based on our technologies, but we may not be successful in achieving this transition. As of September 30, 2019, we had an accumulated deficit of $358.1 million. With the exception of 2012, we have incurred losses since our inception. We expect to have significant losses and negative cash flow for at least the next several years, as we incur additional costs and expenses for the continued development of our technology, including the ongoing expenses of research, development, commercialization and administration. The Company held unrestricted cash and cash equivalents of $2.9 million at September 30, 2019. Our present capital resources are not sufficient to fund our planned operations for a twelve month period, and therefore, raise substantial doubt about our ability to continue as a going concern. As a result, our independent registered public accounting firm included an explanatory paragraph in its report on our financial statements as of and for the year ended December 31, 2018 with respect to this uncertainty. Additional risks are discussed more fully in the section entitled “Risk Factors” following this prospectus summary. These risks include, but are not limited to, the following:


•	We have a history of net losses and our future profitability is uncertain.


•	We will be required to raise additional funds to finance our operations and remain a going concern; we may not be able to do so when necessary, and/or the terms of any financings may not be advantageous to us.


•	Raising additional funds may cause dilution to our existing stockholders, restrict our operations or require us to relinquish rights to our technologies.


•	The holders of any Series B Preferred Stock issued pursuant to the private placement concurrent with this offering will be entitled to rights and preferences that are greater than the rights and preferences of the holders of our common stock, including preferential payments upon a liquidation, as well as a dividend and the right to approve certain corporate transactions.

•

Any Series B Preferred Stock issued pursuant to the private placement concurrent with this offering will be redeemable at the option of the holders twelve months after issue, which may cause us to have to liquidate or declare bankruptcy if we do not have the funds to redeem those shares at the at time. Further, the redemption feature may require us to treat these shares as debt on our financial statements.


•	We have recently changed our corporate strategy to focus on the crop science industry, and our technologies in this area are at a very early stage of development. We may never commercialize a technology or product that will generate meaningful, or any, revenues.


•	A portion of our revenue to date has been generated from government grants; continued availability of government grant funding is uncertain and contingent on compliance with the requirements of the grant.


•	Our government grants may subject us to government audits, which could expose us to penalties.


•	Our crop science product development cycle is lengthy and uncertain and will depend heavily on future collaborative partners.


•	Our crop science program may not be successful in developing commercial products.


•	Even if we or our collaborators are successful in developing commercial products that incorporate our traits, such products may not achieve commercial success.


•	We may not be successful using our Camelina platform to develop and commercialize niche crops to produce specialty oils and/or PHA biomaterials.


•	Consumer and government resistance to genetically modified organisms may negatively affect the ability to commercialize crops containing our traits, as well as our public image.


•	We may not be able to obtain or maintain the necessary regulatory approvals for our products, which could restrict our ability to sell those products in some markets.


•	If ongoing or future field trials conducted by us or our collaborators are unsuccessful, we may be unable to complete the regulatory process for, or commercialize, our products in development on a timely basis.


•	Competition in traits and seeds is intense and requires continuous technological development, and, if we are unable to compete effectively, our financial results will suffer.


•	Our business is subject to various government regulations and if we or our collaborators are unable to timely complete the regulatory process for our products in development, our or our collaborators’ ability to market our traits could be delayed, prevented or limited.


•	The products of third parties or the environment may be negatively affected by the unintended appearance of our yield trait genes.


•	We rely on third parties to conduct, monitor, support, and oversee field trials and, in some cases, to maintain regulatory files for those products in development, and any performance issues by third parties, or our inability to engage third parties on acceptable terms, may impact our or our collaborators’ ability to complete the regulatory process for or commercialize such products.


•	If we lose key personnel or are unable to attract and retain necessary talent, we may be unable to develop or commercialize our products under development.


•	Patent protection for our technologies is both important and uncertain.


•	Third parties may claim that we infringe their intellectual property, and we could suffer significant litigation or licensing expense as a result.


•	Portions of our crop science technology are owned by or subject to retained rights of third parties.


•	We may not be successful in obtaining necessary rights to additional technologies for the development of our products through acquisitions and in-licenses.


•	The intellectual property landscape around genome editing technology, such as CRISPR, is highly dynamic and uncertain, and any resolution of this uncertainty could have a material adverse effect on our business.


•	We rely in part on trade secrets to protect our technology, and our failure to obtain or maintain trade secret protection could harm our business.


•	A material weakness was identified in our internal control over financial reporting, which could impact our business and financial results.


•	Trading volume in our stock is low and an active trading market for our common stock may not be available on a consistent basis to provide stockholders with adequate liquidity. Our stock price may be extremely volatile, and our stockholders could lose a significant part of their investment.


•	We may not be able to maintain the listing of our common stock on The Nasdaq Capital Market.


•	Provisions in our certificate of incorporation and by-laws and Delaware law might discourage, delay or prevent a change of control of our company or changes in our management and, therefore, depress the trading price of our common stock.


•	Concentration of ownership among our existing officers, directors and principal stockholders may prevent other stockholders from influencing significant corporate decisions and depress our stock price.

Issuer	Yield10 Bioscience, Inc.
Class A Units Offered	We are offering 2,777,777 Class A Units. Each Class A Unit consists of (i) one share of our common stock, (ii) a Series A common warrant to purchase one share of our common stock at an exercise price per share of common stock equal to $[●] and (iii) a Series B common warrant to purchase one share of our common stock at an exercise price share of common stock equal to $[●]. The Class A Units will not be certificated and the shares of common stock, Series A common warrants and Series B common warrants that are part of such unit are immediately separable and will be issued separately in this offering.
Class A Units Offered	This prospectus also relates to the offering of shares of our common stock issuable upon the exercise of the warrants that are part of the Class A Units.
Assumed Public Offering Price per Class A Unit	$0.36 combined price for each Class A Unit.
Class B Units Offered	We are offering up to 4,000 Class B Units to purchasers who prefer not to beneficially own more than 4.99% (or, at the election of the purchaser, 9.99%) of our outstanding common stock following the consummation of this offering. Each Class B Unit consists of (i) one share of Series A Preferred Stock, par value $0.01 per share, convertible into a number of shares of common stock equal to $1,000.00 divided by the assumed conversion price of $0.36 (the “Conversion Price”), (ii) a number of Series A common warrants to purchase shares of our common stock equal to 100% of the common stock underlying each share of Series A Preferred Stock and (iii) a number of Series B common warrants to purchase shares of our common stock equal to 100% of the common stock underlying each share of Series A Preferred Stock.

Offering Price per Class B Unit	$1,000.00 combined price for each Class B Unit.



Concurrent Private Placement	Concurrently with the offering being made pursuant to this prospectus, we are offering to sell to Jack W. Schuler, our largest shareholder, and entities related to him up to $4.6 million of our Series B Convertible Preferred Stock, Series A warrants and Series B warrants pursuant to a concurrent private placement. Each share of Series B Preferred Stock, par value $0.01 per share, is automatically converted into a number of shares of common stock equal to $1,000.00 divided by the assumed Conversion Price of $0.36 upon approval of the Charter Amendment. We will also seek stockholder approval for the issuance by us in the concurrent private placement of the Series B Preferred Stock, Series A warrants and Series B warrants, as required by Nasdaq Marketplace Rule 5635(d), because we will be issuing securities convertible into our common stock at a discount to market price in an amount greater than 19.99% of our outstanding common stock. The number of Series A common warrants to purchase shares of common stock to be sold in the concurrent private placement is equal to 100% of the common stock underlying each share of Series B Preferred Stock. The number of Series B common warrants to purchase shares of our common stock to be sold in the concurrent private placement is equal to 100% of the common stock underlying each share of Series B Preferred Stock.
Description of Series A Convertible Preferred Stock	Each share of Series A Preferred Stock is convertible at any time at the holder’s option into a number of shares of common stock equal to $1,000.00 divided by the Conversion Price. Notwithstanding the foregoing, we shall not effect any conversion of Series A Preferred Stock, with certain exceptions, to the extent that, after giving effect to an attempted conversion, the holder of shares of Series A Preferred Stock (together with such holder’s affiliates, and any persons acting as a group together with such holder or any of such holder’s affiliates) would beneficially own a number of shares of our common stock in excess of 4.99% (or, at the election of the purchaser, 9.99%) of the shares of our common stock then outstanding after giving effect to such exercise. For additional information, see “Description of Capital Stock” on page 56 of this prospectus.



Description of Series B Convertible Preferred Stock to be sold in the Concurrent Private Placement	The Series B Preferred Stock will not be convertible into shares of common stock until the approval of the Charter Amendment. If the Charter Amendment is approved, each share of Series B Preferred Stock will automatically be converted into a number of shares of common stock equal to $1,000.00 divided by the assumed Conversion Price of $0.36. The Series B Preferred Stock has various rights that are superior to other securities issued by us. Specifically, the Series B Preferred Stock is redeemable for cash at the election of the holders if the Charter Amendment has not occurred by the date that is twelve months from the date of issuance of the Series B Preferred Stock. Further, the Series B Preferred Stock has a cumulative quarterly dividend right, payable starting March 31, 2020, pursuant to which the holders of the Series B Preferred Stock will be entitled to receive a dividend equal initially to (i) 2% of the stated value of the Series B Preferred Stock plus (ii) all accrued and unpaid dividends, which dividends are payable in additional shares of Series B Preferred Stock. The dividend rate will increase by 2% on each quarterly dividend payment date for as long as the Series B Preferred Stock remains outstanding. In addition, the Series B Preferred Stock has a liquidation preference such that in the event of a liquidation of the company, holders of the Series B Preferred Stock would be paid the stated value of the Series B Preferred Stock plus the amount of the accrued dividends to the point of liquidation prior to any payment to holders of junior securities, including the common stock. The holders of the Series B Preferred Stock will also have the right to approve specified corporate transactions, including the issuance of any securities that would be senior to the Series B Preferred Stock, material changes in our business, material acquisitions of assets, appointments of new executive officers, liquidations, repurchases of shares, and other matters as set forth in the Certificate of Designations for the Series B Preferred Stock.
Description of Series A Warrants	Each Series A common warrant will have an initial exercise price per share equal to $[•] per share, subject to appropriate adjustment in the event of recapitalization events, stock dividends, stock splits, stock combinations, reclassifications, reorganizations or similar events affecting our common stock. We do not currently have a sufficient number of authorized shares of common stock to cover shares issuable upon exercise of the warrants being offered by this prospectus. As a result, before any warrants can become exercisable, we will seek stockholder approval of an amendment to our certificate of incorporation to implement an increase in the number of authorized shares of our common stock at a special meeting of stockholders to be called for this purpose. While our board of directors will unanimously recommend that stockholders approve the Charter Amendment, we cannot assure you that we will be able to obtain the requisite stockholder approval of the Charter Amendment. The Series A common warrants will be exercisable on any day on or after the date on which we publicly announce, through filing of a Current Report on Form 8-K, that we have sufficient authorized shares of common stock as a result of the Charter Amendment, and will expire two and one half years after the date of issuance.
Description of Series A Warrants	There is no established public trading market for the warrants, and we do not expect a market to develop. In addition, we do not intend to apply for a listing of the Series A common warrants on any national securities exchange.



Description of Series B Warrants	Each Series B common warrant will have an initial exercise price of $[•] per share, subject to appropriate adjustment in the event of recapitalization events, stock dividends, stock splits, stock combinations, reclassifications, reorganizations or similar events affecting our common stock, will be exercisable on any day on or after the date on which we publicly announce, through filing of a Current Report on Form 8-K, that we have sufficient authorized shares of common stock as a result of the Charter Amendment, and will expire seven and one half years after the date of issuance.
Description of Series B Warrants	There is no established public trading market for the warrants, and we do not expect a market to develop. In addition, we do not intend to apply for a listing of the Series B Common Warrants on any national securities exchange.
Shares of common stock underlying the warrants offered hereby	27,771,554 shares.
Shares of common stock to be outstanding after this offering (1)	15,296,794 shares (26,404,794 on an as-converted basis, assuming the conversion in full of the Series A Preferred Stock, but not including the conversion of the Series B Preferred Stock).

RISK FACTORS

An investment in shares of our common stock involves a high degree of risk. You should carefully consider the following information about these risks, together with the other information appearing elsewhere in this prospectus, including our financial statements and related notes thereto, before deciding to invest in our common stock. The occurrence of any of the following risks could have a material adverse effect on our business, financial condition, results of operations and future growth prospects. In these circumstances, the market price of our common stock could decline, and you may lose all or part of your investment. We undertake no obligation to update any forward-looking statements, whether as a result of new information, future events or otherwise. You are advised, however, to consult any further disclosure we make in our reports filed with the Securities and Exchange Commission (the "SEC").

Risks Relating to our Financial Position

We have a history of net losses and our future profitability is uncertain.

We have recorded losses in every year since our inception, with the exception of 2012. As of September 30, 2019, our accumulated deficit was $358.1 million. Since 1992, we have been engaged primarily in research and development and early-stage commercial activities. Because our crop science technology is at an early stage of development, we cannot be certain that the Yield10 Bioscience business will generate sufficient revenue to become profitable. We expect to continue to have significant losses and negative cash flow for at least the next several years, as we incur additional costs and expenses for the continued development of our technology, including the ongoing expenses of research, development, commercialization and administration. The amount we spend will impact our need for capital resources as well as our ability to become profitable and this will depend, in part, on the number of new technologies that we attempt to develop. We may not achieve any or all of these goals and, thus, we cannot provide assurances that we will ever be profitable or achieve significant, or any, product revenues.

Following this offering and the concurrent private placement, we will have a limited number of authorized shares of common stock available for issuance and will need to seek stockholder approval to amend our charter to effect an increase in our authorized shares of common stock.

Immediately following this offering and the concurrent private placement, we will not have a sufficient number of authorized shares to permit exercise of the warrants or the conversion of the Series B Preferred Stock. We will seek stockholder approval of an amendment to our certificate of incorporation to effect an increase the number of authorized shares of common stock, in an amount sufficient to permit the exercise in full of the warrants and fund our business. If we do not receive the requisite stockholder approval to enable us to issue equity in the future, our operations will likely be materially adversely impacted.

In addition, an increase in the authorized number of shares of common stock and the subsequent issuance of such shares could have the effect of delaying or preventing a change in control of our company without further action by our stockholders. Shares of authorized and unissued common stock could, within the limits imposed by applicable law, be issued in one or more transactions which would make a change in control of our company more difficult, and therefore less likely. In addition, the availability of a greater number of authorized shares could result in additional dilution to existing stockholders and investors in this offering.

We will need to secure additional funding to finance our operations and may not be able to do so when necessary, and/or the terms of any financings may not be advantageous to us.

As of September 30, 2019, we held unrestricted cash and cash equivalents of $2.9 million. In March 2019, we closed on a registered direct offering of our common stock, raising $2.6 million, net of offering costs. We follow the guidance of Accounting Standards Codification ("ASC") Topic 205-40, Presentation of Financial Statements-Going Concern, in order to determine whether there is substantial doubt about the Company's ability to continue as a going concern for one year after the date its financial statements are issued. We have concluded, and our independent auditors have agreed, that substantial doubt does exist as to our ability to continue as a going concern under this standard, and as a result, our auditors have included an explanatory paragraph in their audit

opinion for our fiscal year ended December 31, 2018. We will need to secure additional funds in the near term to continue operations.

We continue to face significant challenges and uncertainties and, as a result, our available capital resources may be consumed more rapidly than currently expected due to any or all of the following:


•	lower than expected revenues from grants and licenses related to our technologies;


•	changes we may make to the business that affect ongoing operating expenses;


•	further changes we may make to our business strategy;


•	changes in our research and development spending plans; and


•	other items affecting our forecasted level of expenditures and use of cash resources.

We will require additional capital resources to support the implementation of our business strategy and we may pursue one or more of a variety of financing options, including public or private equity financing, secured or unsecured debt financing, equity or debt bridge financing, as well as licensing or other collaborative arrangements. There can be no assurance that our financing efforts will be successful. If we are not able to secure such additional capital resources or otherwise fund our operations, we will be forced to explore strategic alternatives and/or wind down our operations and pursue options for liquidating our remaining assets, including intellectual property and equipment.

If we issue equity or debt securities to raise additional funds in the future, we may incur fees associated with such issuances, our existing stockholders may experience dilution from the issuance of new equity securities, we may incur ongoing interest expense and be required to grant a security interest in our assets in connection with any debt issuance, and the new equity or debt securities may have rights, preferences and privileges senior to those of our existing stockholders. In addition, utilization of our net operating loss and research and development credit carryforwards may be subject to significant annual limitations under Section 382 of the Internal Revenue Code of 1986, as amended (the "Code"), due to ownership changes resulting from equity financing transactions. If we raise additional funds through collaboration, licensing or other similar arrangements, it may be necessary to relinquish valuable rights to our potential products or proprietary technologies or grant licenses on terms that are not favorable to us.

The holders of the Series B Preferred Stock will be entitled to rights and preferences that are greater than the rights and preferences of the holders of our common stock, including preferential payments upon a liquidation, as well as a dividend and the right to approve certain corporate transactions.

Holders of our Series B Preferred Stock will be entitled to a number of rights and preferences which holders of shares of our common stock and Series A Preferred Stock do not and will not have. Among these rights and preferences is a preference on liquidation of the Company, which means that holders of the Series B Preferred Stock will be entitled to receive the proceeds out of any sale or liquidation of the Company before any such proceeds are paid to holders of our common stock or Series A Preferred Stock. In general, if the proceeds received upon any sale or liquidation do not exceed the total liquidation proceeds payable to the holders of the Series B Preferred Stock, holders of common stock and Series A Preferred Stock would receive no value for their shares upon such a sale or liquidation. In addition, shares of the Series B Preferred Stock accrue dividends at a rate of 2% per year for a period of five years from the date on which the shares of Series B Preferred Stock were issued.

Holders of the Series B Preferred Stock also have significant rights with respect to certain actions that we may wish to take from time to time. At any time when any shares of Series B Preferred Stock remain outstanding, we may not, without the consent of the holders of a majority of the shares of Series B Preferred Stock:


•	amend any provision of our Certificate of Incorporation or Bylaws that changes the rights of the Series B Preferred Stock;


•	reclassify, alter or amend any of our securities in a manner that adversely affects the rights of the Series B Preferred Stock;

•

authorize, create, designate, issue or sell any class or series of capital stock (or rights, options, warrants or other securities convertible into or exercisable or exchangeable for capital stock) that would be classified as senior to or on a par with the Series B Preferred Stock, except in connection with the declaration and payment of dividends to holders of outstanding shares of Series B Preferred Stock;


•	materially change the nature of our business;


•	make business acquisitions over a twelve-month period for payment by the Company in excess of $1,000,000;


•	sell or otherwise dispose of any capital stock or assets of the Company outside the ordinary course of business;


•	repay, repurchase or redeem any indebtedness except as required pursuant to the terms of such indebtedness;


•	adopt a shareholder rights plan, or other anti-takeover plan or device;


•	liquidate, dissolve, wind-up, or merge with another entity;


•	hire, terminate, increase the salary of or modify any other material employment terms of any member of our senior management;


•	incur indebtedness in excess of $1,000,000;


•	enter into any agreement or obligation that restricts our ability to perform our obligations to the holders of Series B Preferred Stock, including the ability to pay dividends or make redemptions or other liquidation payments;


•	purchase or redeem or pay or declare any dividend, or make any distribution on, any of our capital stock other than the Series B Preferred Stock; or


•	enter into any agreement to do any of the above that is not expressly made conditional on obtaining the affirmative vote or written consent of the holders of Series B Preferred Stock.

As a result, we will not be able to take any of these actions without first seeking and obtaining the approval of the holders of the Series B Preferred Stock. We may not be able to obtain such approval in a timely manner or at all, even if we think that taking the action for which we seek approval is in the best interests of the Company.

The Series B Preferred Stock will be redeemable at the option of the holders twelve months after issuance, which may cause us to have to liquidate or declare bankruptcy if we do not have the funds to redeem those shares at that time. Further, the redemption feature may require us to treat these shares as debt on our financial statements.

We will be required to redeem the Series B Preferred Stock for cash from the holders of those shares on the date that is twelve months after the issuance date, if the Charter Amendment is not approved by our shareholders by that time. If we do not have the funds available at that time to redeem those shares, we could be forced to liquidate or declare bankruptcy. The Series B Preferred Stock will have a liquidation preference in any such event, which would mean that any remaining assets could be transferred to the holders of the Series B Preferred Stock and that the common stockholders and any remaining Series A Preferred holders would receive nothing for their shares.

In addition, the accounting rules to which we are subject may require us to treat the Series B Preferred Stock as a debt security, in light of the redemption feature. This may have a materially negative effect on our financial statements.

Inadequate funding for the SEC could hinder our ability to access the public markets and obtain necessary capital in order to properly capitalize and continue our operations.

Government funding of the SEC is subject to the political process, which is inherently fluid and unpredictable. Over the last several years, including a period from late December 2018 through January 2019, the U.S. government has shut down several times and regulatory agencies such as the SEC have had to furlough employees and stop activities. Future government shutdowns could affect our ability to access the public markets and obtain necessary capital in order to properly capitalize and continue our operations, to the extent we need or elect to pursue a financing for which a registration statement must be declared effective by the SEC Staff.

We have changed our corporate strategy to focus on the crop science industry, and our technologies in this area are at a very early stage of development. We may never commercialize a technology or product that will generate meaningful, or any, revenues.

In July 2016, our board of directors approved a plan to implement a strategic restructuring under which Yield10 Bioscience has become our core business. As part of the restructuring, we discontinued our biopolymer operations, eliminated positions in our biopolymer operations and corporate organization, and sold certain of our biopolymer business assets.

The crop science products and technologies we are currently developing as a result of our strategic repositioning are at a very early stage of development, and the process of developing them is lengthy and uncertain. In addition, our current management has limited experience in developing technologies for the crop science industry and has never commercialized a product or technology in this industry. We may never reach a point at which our efforts result in products that allow us to achieve revenue from their license or sale.

There can be no assurance that we will be able to comply with the continued listing standards of The Nasdaq Capital Market.

We cannot assure you that we will be able to comply with the standards that we are required to meet in order to maintain a listing of our common stock on The Nasdaq Capital Market ("Nasdaq"). Nasdaq listing rules require us to maintain certain closing bid price, stockholders’ equity and other financial metric criteria in order for our common stock to continue trading on Nasdaq. Nasdaq Listing Rule 5550(a)(2) requires listed securities to maintain a minimum bid price of $1.00 per share, and Listing Rule 5810(c)(3)(A) provides that a failure to meet the minimum bid price requirement exists if the deficiency continues for a period of 30 consecutive business days.

On June 25, 2019, we were notified by Nasdaq that our common stock had not maintained the minimum closing bid price of $1.00 per share for thirty consecutive business days. We have 180 days, or until December 23, 2019, to regain compliance by maintaining a closing bid price of $1.00 or higher for a minimum of ten consecutive business days. In the event that we do not regain compliance by December 23, 2019, we may be eligible for an additional 180 days provided that we continue to meet all other Nasdaq continued listing standards and provide a written notice of our intention to cure the deficiency during the additional extension period by effecting a reverse stock split, if necessary. If we fail to cure our current stock price deficiency or we do not continue to meet all applicable Nasdaq requirements in the future, including those relating to the minimum stockholders' equity requirement, for which we must maintain stockholders' equity of at least $2.5 million, and Nasdaq determines to delist our common stock, the delisting could substantially decrease trading in our common stock and adversely affect the market liquidity of our common stock; adversely affect our ability to obtain financing on acceptable terms, if at all, for the continuation of our operations; and harm our business. At September 30, 2019, our consolidated stockholders' equity balance was $2.6 million. Additionally, the market price of our common stock may decline further, and stockholders may lose some or all of their investment.

Currently, the sole source of our revenue is government grants; continued availability of government grant funding is uncertain and contingent on compliance with the requirements of the grant.

Historically, a portion of our revenue has been generated from payments to us from government entities in the form of government grants, whereby we are reimbursed for certain expenses incurred in connection with our research and development activities, subject to our compliance with the specific requirements of the applicable grant, including rigorous documentation requirements. To the extent that we do not comply with these requirements, the expenses that we incur may not be reimbursed. Any of our existing grants or new grants that we may obtain in the future may be terminated or modified.

Our ability to obtain grants or incentives from government entities in the future is subject to the availability of funds under applicable government programs and approval of our applications to participate in such programs. The application process for these grants and other incentives is highly competitive. We may not be successful in obtaining any additional grants, loans or other incentives. Recent political focus on reducing spending at the U.S. federal and state levels may continue to reduce the scope and amount of funds dedicated to crop science products, if such funds will continue to be available at all. To the extent that we are unsuccessful in being awarded any additional government grants in the future, we would lose a potential source of revenue.

Our government grants may subject us to government audits, which could expose us to penalties if we have failed to comply with the terms of the grants.

We may be subject to audits by government agencies as part of routine audits of our activities funded by our government grants. As part of an audit, these agencies may review our performance, cost structures and compliance with applicable laws, regulations and standards and the terms and conditions of the grant. If any of our costs are found to be allocated improperly, the costs may not be reimbursed, and any costs already reimbursed for such contract may have to be refunded. Accordingly, an audit could result in a material adjustment to our results of operations and financial condition. Moreover, if an audit uncovers improper or illegal activities, we may be subject to civil and criminal penalties and administrative sanctions.

Risks Relating to our Yield10 Bioscience Crop Science Program

The crop science product development cycle is lengthy and uncertain, and our progress will depend heavily on our ability to attract third-party investment in research under license agreements and on our ability to establish future collaborative partnerships to develop and commercialize our innovations.

The technology and processes used in our crop science program and the application of our technology to enhance photosynthetic efficiency of crops are at an early stage of development. Research and development in the seed, agricultural biotechnology, and larger agriculture industries is expensive and prolonged and entails considerable uncertainty. Completion of development work with respect to our products will require a significant investment of both time and money, if it can be completed at all. We expect that collaborations with established agricultural industry companies will be required to successfully develop and commercialize our innovations. Our initial development strategy is to make it attractive for established agricultural industry companies to invest financial and technical resources to introduce our traits into their elite germplasm for event selection and evaluation under research licenses. For example, in 2017 we entered into a non-exclusive research license with Monsanto, which was subsequently acquired by Bayer AG (“Bayer”), pursuant to which we granted Monsanto a non-exclusive research license to evaluate our novel C3003 and C3004 yield traits in soybean. We expanded the agreement with Bayer in 2019 to cover a new discovery and intellectual property related to C3004. In September 2018, we granted a non-exclusive research license to Forage Genetics, a subsidiary of Land O’Lakes, Inc., to evaluate five of our novel yield traits in forage sorghum. The traits included in the research license include C3003 as well as four traits from our GRAIN platform, C4001, C4002, C4003 and C4029. We may not be successful in establishing or maintaining suitable relationships with established agricultural industry companies for research licenses in the future, and there can be no assurance that any such relationships will result in future collaboration agreements to develop and commercialize our innovations, with terms that are satisfactory to us or at all. In addition, industry collaborators have significant resources and development capabilities and may develop products and technologies that compete with or negatively impact the development and commercialization of our technologies.

Any potential collaborative partnerships that we may enter into in the future may not be successful, which could adversely affect our ability to develop and commercialize our innovations.

We expect that collaborations with established agricultural industry companies will be required for us to successfully develop and commercialize our innovations. The agriculture industry is highly concentrated and dominated by a small number of large companies, which could impact efforts to form the collaborations that we will need in order to complete the development of our products. To the extent that we pursue such arrangements, we will face significant competition in seeking appropriate partners. Moreover, such arrangements are complex and time-consuming to negotiate, document, implement and maintain. We may not be successful in establishing or implementing such arrangements. The terms of any partnerships, joint ventures or other collaborative arrangements that we may establish may not be favorable to us.

The success of any future collaborative partnerships is uncertain and will depend heavily on the efforts and activities of our potential partners. Such arrangements are subject to numerous risks, including the risks that:


•	our partners may have significant discretion in determining the efforts and resources that they will apply to the arrangement;


•	our partners may not pursue the development and commercialization of our product candidates based on trial results, changes in their strategic focus, competing priorities, availability of funding, or other external factors;


•	our partners may delay or abandon field trials, fail to conduct field trials that produce sufficient conclusory data, provide insufficient funding for field trials, or repeat or conduct new field trials;


•	partners who have marketing, manufacturing and distribution rights with respect to a product may not commit sufficient resources to, or otherwise not perform satisfactorily in carrying out, these activities;


•	to the extent that such arrangements provide for exclusive rights, we may be precluded from collaborating with others;


•	our partners may not properly maintain or defend our intellectual property rights, or may use our intellectual property or proprietary information in a way that gives rise to actual or threatened litigation that could jeopardize or invalidate our intellectual property or proprietary information or expose us to potential liability;


•	disputes may arise between us and a partner that causes the delay or termination of the research, development or commercialization of our current or future products, or that results in costly litigation or arbitration that diverts management attention and resources;


•	such arrangements may be terminated, and, if terminated, may result in a need for additional capital for our independent pursuit of matters previously covered by such arrangement;


•	our partners may own or co-own intellectual property that results from our arrangement; and


•	a partner’s sales and marketing activities or other operations may not be in compliance with applicable laws resulting in civil or criminal proceedings.

Our crop science program may not be successful in developing commercial products.

We and our potential future collaborators may spend many years and dedicate significant financial and other resources developing traits that will never be commercialized. Seeds containing the traits that we develop may never become commercialized for any of the following reasons:


•	our traits may not be successfully validated in the target crops;


•	our traits may not achieve our targeted yield improvements;


•	we may not be able to secure sufficient funding to progress our traits through development and commercial validation;


•	our traits may not have the desired effects sought by future collaborators for the relevant crops;


•	development and validation of traits, particularly during field trials, may be adversely affected by environmental or other circumstances beyond our control;


•	we or our future collaborators may be unable to obtain the requisite regulatory approvals for the seeds containing our traits, to the extent regulatory approvals are required;


•	competitors may launch competing or more effective seed traits or seeds;


•	a market may not exist for seeds containing our traits or such seeds may not be commercially successful;


•	future collaborators may be unable to fully develop and commercialize products containing our seed traits or may decide, for whatever reason, not to commercialize such products;


•	we may be unable to patent our traits in the necessary jurisdictions; and


•	our efforts to develop niche crop products based on our Camelina platform, including specialty oils and PHB biomaterials are in the early stages and may not be successful.

If any of these things were to occur, it could have a material adverse effect on our business and our results of operations. Research and development in the crop science industry is expensive and prolonged and entails considerable uncertainty. Because of the stringent product performance and safety criteria applied in development of crop science products, products currently under development may neither survive the development process nor ultimately receive any requisite regulatory approvals that may be needed to market such products. Even when such approvals are obtained, there can be no assurance that a new product will be commercially successful. In addition, research undertaken by competitors may lead to the launch of competing or improved products, which may affect sales of any products that we are able to develop.

Even if we or our future collaborators are successful in developing commercial products that incorporate our traits, such products may not achieve commercial success.

Our strategy depends upon our or our future collaborators’ ability to incorporate our traits into a wide range of crops in significant markets and geographies. Even if we or our future collaborators are able to develop commercial products that incorporate our traits, any such products may not achieve commercial success for one or more of the following reasons, among others:


•	products may fail to be effective in particular crops, geographies, or circumstances, limiting their commercialization potential;


•	our competitors, or competitors of our collaborators, may launch competing or more effective traits or products;


•	significant fluctuations in market prices for agricultural inputs and crops could have an adverse effect on the value of our traits;


•	farmers are generally cautious in their adoption of new products and technologies, with conservative initial purchases and proof of product required prior to widespread deployment, and accordingly, it may take several growing seasons for farmers to adopt our or our collaborators’ products on a large scale;


•	we may not be able to produce high-quality seeds in sufficient amounts to meet demand; and


•	we may not be able to secure the financial or other resources needed to achieve commercial success.

Our financial condition and results of operations could be materially and adversely affected if any of the above were to occur.

Our estimates of market opportunity and forecasts of market growth may prove to be inaccurate, and even if the markets in which we may compete in the future achieve growth, our business could fail to achieve the same growth rates as others in the industry.

Market opportunity estimates and market growth forecasts are subject to significant uncertainty and are based on assumptions and estimates that may not prove to be accurate. Our estimates and forecasts relating to the size and expected growth of the global seed industry and the biotechnology seeds market, and the estimated ranges of incremental value increase that a novel, newly developed crop trait may produce, may prove to be inaccurate. Even if the markets in which we may compete in the future achieve these opportunity estimates and market growth forecasts, our business could fail to grow at similar rates, if at all.

If ongoing or future field trials conducted by us or our future collaborators are unsuccessful, we may be unable to complete the regulatory process for, or commercialize, our products in development on a timely basis.

The successful completion of multi-year, multi-site field trials is critical to the success of product development and marketing efforts for products containing our traits. If our ongoing or future field trials, or those of our future collaborators, are unsuccessful or produce inconsistent results or unanticipated adverse effects on crops, or if we or our collaborators are unable to collect reliable data, regulatory review of products in development containing our traits could be delayed or commercialization of products in development containing our traits may not be possible. In addition, more than one growing season may be required to collect sufficient data to develop or market a product containing our traits, and it may be necessary to collect data from different geographies to prove performance for customer adoption. Even in cases where field trials are successful, we cannot be certain that additional field trials conducted on a greater number of acres, or in different crops or geographies, will be successful. Generally, we or our research licensees conduct these field trials, or we pay third parties, such as farmers, consultants, contractors, and universities, to conduct field trials on our behalf. Poor trial execution or data collection, failure to follow required agronomic practices, regulatory requirements, or mishandling of products in development by our collaborators or these third parties could impair the success of these field trials.

Many factors that may adversely affect the success of our field trials are beyond our control, including weather and climatic variations, such as drought or floods, severe heat or frost, hail, tornadoes and hurricanes, uncommon or unanticipated pests and diseases, or acts of protest or vandalism. For example, if there were a prolonged or permanent disruption to the electricity, climate control, or water supply operating systems in our greenhouses or laboratories, the crops in which we or our collaborators are testing our traits and the samples we or our collaborators store in freezers, both of which are essential to our research and development activities including field tests, could be severely damaged or destroyed, adversely affecting these activities and thereby our business and results of operations. Unfavorable weather conditions including drought or excessive rain, or fluctuations in temperature, which we have experienced from time to time in our field trials, can also reduce both acreages planted and incidence, or timing of, certain crop diseases or pest infestations, each of which may halt or delay our field trials. Any field test failure we may experience may not be covered by insurance and, therefore, could result in increased cost for the field trials and development of our traits, which may negatively impact our business, results of operations, and ability to secure financing. Such factors outside of our control can create substantial volatility relating to our business and results of operations.

Competition in the market for traits and seeds is intense and requires continuous technological development, and, if we are unable to compete effectively, our financial results will suffer.

We face significant competition in the markets in which we operate. The markets for traits and agricultural biotechnology products are intensely competitive and rapidly changing. In most segments of the seed and agricultural biotechnology market, the number of products available to consumers is steadily increasing as new products are introduced. At the same time, the expiration of patents covering existing products reduces the barriers to entry for competitors. We may be unable to compete successfully against our current and future competitors, which may result in price reductions, reduced margins and the inability to achieve market acceptance for any products that we or our future collaborators commercialize containing our traits. In addition, most of our competitors have substantially greater financial, marketing, sales, distribution, research and development, and technical resources than we have, and some of our potential future collaborators have more experience in research and development, regulatory matters, manufacturing, and marketing. We anticipate increased competition in the future as new companies enter the market and new technologies become available. Our technologies may be rendered obsolete or uneconomical by technological advances or entirely different approaches developed by one or more of our competitors, which will prevent or limit our ability to generate revenues from the commercialization of our traits being developed.

Our business is subject to various government regulations in the United States and Canada, the regulatory requirements for our future products in development are evolving and are subject to change, and if there are adverse changes to the current regulatory framework, our or our future collaborators’ ability to market our traits could be delayed, prevented or limited.

In the United States and Canada, where our seed traits and biotechnology-derived plant lines are developed and field tested, changes in regulatory requirements applicable to our seed traits or future products in development containing our traits could result in a substantial increase in the time and costs associated with developing and commercializing future products containing our traits, and could materially affect our ability to meet our desired development timelines or to develop and commercialize a future product containing our traits at all.

In the United States, our seed traits and any future products that are successfully developed containing our seed traits are or will be subject to USDA and U.S. Food and Drug Administration ("FDA") regulatory requirements. The USDA and FDA requirements will vary depending on the particular seed trait and the intended use of any product that will be commercialized. Our business strategy is focused on crop yield traits and we have no current plans for the development of pesticide or herbicide traits, which would be subject to regulation by the U.S. Environmental Protection Agency ("EPA").

Within USDA, the APHIS is responsible for protecting agricultural plants under the Plant Protection Act. USDA-APHIS regulates organisms and products that are known or are suspected to be plant pests or to pose a plant pest risk, including those that have been altered or produced through various genetic engineering techniques. These genetically engineered plants are called “regulated articles” in the relevant USDA-APHIS regulations, which control the import, handling, interstate movement and release into the environment of regulated articles, including certain genetically engineered organisms undergoing confined experimental use or field trials. Seed traits developed using the insertion of recombinant DNA, such as our C3003 yield trait that leverages the biological functions of an algal gene, are regulated articles and are therefore subject to extensive USDA-APHIS oversight, including but not limited to permitting requirements for import, handling, interstate movement and release into the environment.

In recent years, we and others have submitted various petitions to USDA-APHIS to determine whether particular biotechnology-derived plants developed through the use of different genome editing techniques may be considered to be not regulated under the framework administered by the agency. In general, genome editing approaches to novel plant trait development have been considered not regulated by USDA-APHIS. In particular, we have submitted two petitions (also known as the “Am I Regulated?” letter) to USDA-APHIS’s Biotechnology Regulatory Services in order to confirm that the following two oil content traits are not going to be regulated by the agency under 7 CFR part 340: (i) the single trait C3008 Camelina plant line, developed using CRISPR genome editing technology for increased oil content; and (ii) the triple-edited Camelina line that combines three gene traits,

C3008a, C3008b and C3009, to increase oil production. In both cases, USDA-APHIS approved our petitions and confirmed in writing that each of these novel plant lines would not be treated as a regulated article.

The USDA also announced in March 2018 that it would not require an assessment on products that used modern forms of mutagenesis if it was clear these outcomes could occur in nature. The USDA stated at that time that it did not “have any plans to regulate plants that could otherwise have been developed through traditional breeding techniques as long as they are developed without the use of a plant pest as the donor or vector and they are not themselves plant pests.” This USDA policy statement applies to genetic deletions of any size, which would include genome editing through CRISPR-Cas9 and other emerging technologies, although it remains to be seen how this policy announcement will be implemented by USDA-APHIS and what practical effect that may have on seed trait developers like us and our competitors.

There can be no guarantee that the USDA-APHIS governing regulations and policies will not change. We cannot predict whether advocacy groups will challenge existing regulations and USDA determinations, whether the USDA will alter its interpretations of existing regulations, modify existing regulations or promulgate new regulations, or whether additional laws will come into effect. If these or other developments resulted in adverse changes to the current regulatory framework, our seed traits or future products in development containing our traits could be subjected to more burdensome regulatory standards, thereby substantially increasing the time and costs associated with developing and commercializing any future products. Moreover, we cannot assure you that USDA-APHIS will analyze any of our future yield traits or products in development containing our traits in a manner consistent with its analysis of our genome edited yield traits to date. Complying with the USDA’s plant pest regulations for traits that are classified as “regulated articles,” including the permitting requirements for field testing and environmental release, is a costly, time-consuming process and could substantially delay or prevent the commercialization of any future products containing traits that we expected to be deemed non-regulated by USDA-APHIS under 7 CFR part 340.

In addition to USDA-APHIS regulation of plant breeding and planting, a biotechnology-derived plant also will be regulated by the FDA if it is intended to be used as human food or animal feed. The FDA regulates the safety of food for humans and animals, and foods derived from novel plant varieties must meet the same food safety requirements as foods derived from traditionally bred plants (also called conventional foods). Since 1992, the FDA has had in place a voluntary consultation process for developers of bioengineered food (“Biotechnology Consultations”).

Biotechnology Consultations are data-intensive and examine the new food product’s safety and nutritional profile, among other issues. Generally, the FDA has found that such food products do not pose unique health risks to humans or animals, but if a novel allergen or other distinction from the conventional food is present in the new plant variety, the agency may require specific label statements on the product to ensure that consumers are made aware of material differences between genetically engineered and conventional versions. When such a determination cannot be made, the novel plant variety may become subject to FDA premarket review and approval as a food additive.

As part of a broader effort to modernize its regulatory approach to all biotechnology-derived products, the FDA is currently re-evaluating its regulatory approach in light of the increasing prevalence of certain genome edited plants. In January 2017, the FDA asked for public input to help inform its thinking about human and animal foods derived from new plant varieties produced using genome editing techniques. Among other things, the FDA’s request for comments asked for data and information in response to questions about the safety of foods from genome edited plants, such as whether certain categories of genome edited plants present food safety risks different from other plants produced through traditional plant breeding. Subsequently, in October 2018, FDA leadership issued a document entitled the “Plant and Animal Biotechnology Innovation Action Plan” (“Action Plan”) that identified three key priorities for the agency in this area and stated that the FDA has reviewed the comments and other information it received in response to the January 2017 request for comments. The FDA also stated that it intends to develop guidance for industry explaining how the FDA’s existing regulatory policy for foods derived from new plant varieties applies to foods produced using genome editing. The forthcoming draft guidance is expected to be released for public comment in 2019. The FDA also stated in the Action Plan that it intends to begin updating the existing procedures for voluntary Biotechnology Consultations to reflect the agency’s 25 years of experience with foods

derived from biotechnology plants and to incorporate any additional issues related to genome editing of food crops. Such procedural updates are expected to be developed and implemented over the next two years.

We have not participated in any Biotechnology Consultations or engaged in any informal discussions with the FDA about our novel yield traits, whether those traits have been developed using genome editing or traditional genome modification using the insertion of recombinant DNA. Any delay in the regulatory consultation process, or a determination by the FDA that future product candidates containing our traits raise different safety issues than the relevant conventional crop and therefore must be approved by the agency as a new food additive through an intensive premarket safety review process, could increase the costs associated with or delay or prevent the commercialization of the future product candidate. Such delays may lead to reduced acceptance by farmers, food manufacturers or the public and an increase in competitor products that may directly compete with ours. Further, if the FDA enacts new regulations or policies with respect to genome edited plants in particular, such policies could result in additional compliance costs or delay or prevent the commercialization of any potential commercial products containing our seed traits, which could adversely affect our ability to generate revenues and to achieve profitability.

In Canada, genetically engineered crops and the food products into which they are incorporated are regulated by multiple government agencies under a federal framework for the regulation of biotechnology products that is similar to the U.S. system. First, the Canadian Food Inspection Agency ("CFIA") is the lead agency for ensuring that a new agricultural biotechnology crop will not pose new risks to Canadian plants, animals and other agricultural commodities. The CFIA’s Plant Biosafety Office ("PBO") is responsible for conducting environmental assessments of biotechnology-derived plants, referred to as “plants with novel traits” ("PNT"). Authority for the PBO includes both approving confined field trials with the PNT through permits and authorizing their “unconfined release” as a first step towards commercialization. Second, under the Food and Drugs Act and related regulations, Health Canada is responsible for reviewing a pre-market safety assessment that must be submitted by the manufacturer or importer of a “novel food,” a term of art that includes any PNT or other biotechnology-derived foods. Health Canada will evaluate the data and information about the novel food and make a determination regarding whether it is safe and nutritious before it can be sold in Canada, as well as whether any restrictions are warranted under applicable law or the product’s safety profile. Any commercialization of our yield crops in Canada is expected to be done by a third-party collaborator or other partner and complying with Health Canada’s pre-market notification requirement and safety assessment for novel foods would be the obligation of that third-party collaborator.

Our work involving the development, greenhouse testing and field testing of novel yield trait genes in crop plants requires certain government and municipal permits and we must ensure compliance with all applicable regulations including regulations relating to genetically engineered crops. With laboratories and greenhouses in both the U.S. and Canada, we are also subject to regulations governing the shipment of seeds and other plant material between our facilities in the U.S. and Canada, including USDA-APHIS permits for the import and export of plant materials that could pose a risk to domestic agriculture. We also have been conducting field studies of various yield traits in Canada since 2016 under PNT permits issued by Canadian regulators.

Complying with the Canadian regulations is a costly, time-consuming process and could substantially delay or prevent the commercialization of our products. In addition, we cannot assure you that CFIA and Health Canada regulations or the agencies’ implementation of those regulations will not change or that the legislative framework in Canada for biotechnology-derived crops, whether for genome edited plants or plants modified using the insertion of recombinant DNA, will not be amended or otherwise changed in a manner that could result in additional compliance costs or delay or prevent the commercialization of any potential commercial products containing our seed traits, which could adversely affect our ability to generate revenues and to achieve profitability.

Failure to comply with applicable regulatory requirements may, among other things, result in fines, suspensions of regulatory approvals, product recalls, product seizures, operating restrictions and criminal prosecution.

If we or our future collaborators are unable to comply with and timely complete the regulatory process in the United States and Canada for our future products in development, our or our future collaborators’ ability to market our traits could be delayed, prevented or limited.

We apply for and maintain the regulatory permits in the United States and Canada necessary for our operations, particularly those covering our field trials. We anticipate that we or our future collaborators will apply for and maintain regulatory approvals, if any, necessary for the commercialization of any future products containing our seed traits. Even if we and our collaborators make timely and appropriate applications for regulatory permits for our field trials, government delays in issuing such permits can significantly affect the development timelines for our traits, particularly if the planting period for a crop growing season expires before the necessary permits are obtained.

The regulatory process is expensive and time-consuming, and the time required to complete the process is difficult to predict and depends upon numerous factors, including the substantial discretion of the regulatory authorities. We have not completed all phases of the regulatory process for any of our traits in development. Our traits could require a significantly longer time to complete the regulatory process than expected, or may never gain approval, even if we and our collaborators expend substantial time and resources seeking such approval. The time required for regulatory approval, or any delay or denial of such approval, could negatively impact our ability to generate revenues and to achieve profitability and finance our ongoing operations. In addition, changes in regulatory review policies during the development period of any of our traits, changes in, or the enactment of, additional regulations or statutes, or changes in regulatory review practices for a submitted product application may cause a delay in obtaining approval or result in the rejection of an application for regulatory approval. Regulatory approval, if obtained, may be made subject to limitations on the intended uses for which we or our collaborators may market a future product containing our traits. These limitations could adversely affect our potential revenues.

The regulatory environment for genetically engineered crops in jurisdictions outside the United States and Canada varies greatly, and some jurisdictions have more restrictive regulations that could delay, prevent or limit our or our future collaborators’ ability to market our traits.

Other jurisdictions and governmental authorities, including in South America and Asia, are increasingly taking an interest in regulating agricultural products of biotechnology. Regulatory approaches vary by jurisdiction as a result of the existing public health frameworks and phytosanitary laws, as well as other less tangible factors such as cultural and religious norms that may have an impact on individual country risk assessments and decision-making. Each jurisdiction may have its own regulatory framework, which may include restrictions and regulations on planting and growing genetically engineered plants and in the consumption and labeling of foods derived from such novel plants, and which may apply to future products containing our traits. We cannot predict future changes in the global regulatory landscape regarding genetically engineered plants or commercial products incorporating such novel plant varieties. The regulatory environment for such plants is greatly uncertain outside of the U.S. and Canada, and some jurisdictions have more restrictive regulations that could delay, prevent or limit our or our future collaborators’ ability to market our traits.

For example, regulation of all genetically engineered plants in the European Union ("EU") is far more stringent than in the U.S. and Canada. U.S. and Canadian regulators have determined that genome edited plants pose fewer risks than traditional biotechnology-derived plants subjected to modification through the insertion of recombinant DNA. In contrast, a recent EU legal ruling indicated that the existing EU regulations for genetically engineered plants modified by the insertion of recombinant DNA, which were already more stringent than corresponding U.S. and Canadian regulations, should be strictly applied to genome edited plants as well. As a result, there is a sharp distinction between how EU and U.S. and Canadian regulatory agencies oversee novel seed traits, and in particular those that are generated using the more modern techniques of genome editing.

Although we are not currently targeting EU markets for the development or commercialization of future products containing our traits, emerging oversight regimes for genetically engineered products in other jurisdictions may follow the EU approach and impose similarly strict requirements for the release of such products into the environment and their incorporation into human food or other consumer products. Such jurisdictions may also elect to regulate genetically engineered plants without distinguishing between traditional biotechnology-derived plants modified with recombinant DNA and genome edited plants. There is no guarantee that countries for which we may

have or may develop future marketing plans would not take a stricter legal and regulatory approach to controlling genetically engineered plants similar to that of the EU, which could increase regulatory costs and delay, prevent or limit our or our future collaborators’ ability to market our traits in such jurisdictions.

Consumer resistance to genetically engineered crops may negatively affect the ability to commercialize future crops containing our traits, as well as our public image, and may reduce any future sales of seeds containing our yield traits.

Food and feed made from genetically engineered seeds and plants are not accepted by some consumers, and in certain countries production of certain genetically engineered crops is effectively prohibited, including throughout the EU, due to concerns over such products’ effects on food safety and the environment. Advocacy groups have engaged in publicity campaigns and filed lawsuits in various countries against companies and regulatory authorities, seeking to halt regulatory approval activities or influence public opinion against genetically engineered and/or genome edited products. Actions by consumer groups and others also may disrupt research and development or production of genetically engineered plants, seeds or food products that incorporate such novel plant varieties. The high public profile of the biotechnology industry in food and feed production, and a lack of consumer acceptance of the types of products to which we have devoted substantial development resources, could have a negative impact on the commercial success of any of products incorporating our traits that may successfully complete the development process, as to which no assurance can be given, and could materially and adversely affect our ability to obtain future collaborations and to finance our crop science program. Further, we could incur substantial liability and/or legal expenses if there are claims that genetically engineered crops damage the environment or contaminate other farm crops. This could distract our management and cause us to spend resources defending against such claims.

Government policies and regulations, particularly those affecting the agricultural sector and related industries, could adversely affect our operations and our ability to generate future revenues and to achieve profitability.

Agricultural production and trade flows are subject to government policies and regulations. Governmental policies and approvals of technologies affecting the agricultural industry, such as taxes, tariffs, duties, subsidies, incentives and import and export restrictions on agricultural commodities and commodity products can influence the planting of certain crops, the location and size of crop production, and the volume and types of imports and exports. Future government policies in the United States, Canada or in other countries could discourage farmers from using any of our products that may successfully complete the development process, as to which no assurance can be given. Similarly, these policies could discourage food processors from purchasing harvested crops containing our traits or could encourage the use of our competitors’ products, which would put us at a commercial disadvantage and could negatively impact our ability to generate any revenues and to achieve profitability.

The products of third parties, or the environment itself, may be negatively affected by the unintended appearance of our yield trait genes.

The potential for unintended but unavoidable trace amounts, sometimes called “adventitious presence,” of yield trait genes in conventional seed, or in the grain or products produced from conventional or organic crops, could affect acceptance by the general public or by the agricultural industry of these traits. Trace amounts of yield trait genes may unintentionally be found outside our containment area in the products of third parties, which may result in negative publicity and claims of liability brought by such third parties against us. Furthermore, in the event of an unintended dissemination of our genetically engineered materials to the environment, we could be subject to claims by multiple parties, including environmental advocacy groups, as well as governmental actions such as mandated crop destruction, product recalls or additional stewardship practices and environmental cleanup or monitoring. The occurrence of any of these events could have a material adverse effect on our business and results of operations.

Loss of or damage to our elite novel trait events and plant lines would significantly slow our product development efforts.

We have a collection of elite novel trait events and plant lines in which we are developing traits for incorporation into elite germplasm and potential seed products. Our elite novel trait events and plant lines are a key

strategic asset since they form the basis for the introgression of our traits into plant breeding programs. If we suffer loss or damage to our elite novel trait events and plant lines, our research and development activities could be negatively impacted.

Our insurance coverage may be inadequate to cover all the liabilities we may incur.

We face the risk of exposure to liability claims if any products that are successfully developed containing our seed traits, as to which no assurance can be given, are defective and if any product that we develop or any product that uses our technologies or incorporates any of our traits causes injury. Although we carry insurance at levels customary for companies in our industry, such coverage may become unavailable or be inadequate to cover all liabilities we may incur. There can be no assurance that we will be able to continue to maintain such insurance, or obtain comparable insurance at a reasonable cost, if at all. If we are unable to obtain sufficient insurance coverage at an acceptable cost or otherwise, or if the amount of any claim against us exceeds the coverage under our policies, we may face significant expenses.

We rely on third parties to conduct, monitor, support, and oversee field trials and, in some cases, to maintain regulatory files for those products in development, and any performance issues by third parties, or our inability to engage third parties on acceptable terms, may impact our or our future collaborators’ ability to complete the regulatory process for or commercialize such products.

We rely on third parties to conduct, monitor, support, and oversee field trials. As a result, we have less control over the timing and cost of these trials than if we conducted these trials with our own personnel. If we are unable to maintain or enter into agreements with these third parties on acceptable terms, or if any such engagement is terminated prematurely, we may be unable to conduct and complete our trials in the manner we anticipate. In addition, there is no guarantee that these third parties will devote adequate time and resources to our studies or perform as required by our contract or in accordance with regulatory requirements, including maintenance of field trial information regarding our products in development. If any of these third parties fail to meet expected deadlines, fail to transfer to us any regulatory information in a timely manner, fail to adhere to protocols, or fail to act in accordance with regulatory requirements or our agreements with them, or if they otherwise perform in a substandard manner or in a way that compromises the quality or accuracy of their activities or the data they obtain, then field trials of our traits in development may be extended or delayed with additional costs incurred, or our data may be rejected by the applicable regulatory agencies. Ultimately, we are responsible for ensuring that each of our field trials is conducted in accordance with the applicable protocol and with legal, regulatory and scientific standards, and our reliance on third parties does not relieve us of our responsibilities. We could be subject to penalties, fines and liabilities if our third-party contractors fail to perform as required.

If our relationship with any of these third parties is terminated, we may be unable to enter into arrangements with alternative parties on commercially reasonable terms, or at all. Switching or adding service providers can involve substantial cost and require extensive management time and focus. Delays may occur, which can materially impact our ability to meet our desired development timelines. If we are required to seek alternative service arrangements, the resulting delays and potential inability to find a suitable replacement could materially and adversely impact our business.

In addition, there has been an increasing trend towards consolidation in the agricultural biotechnology industry. Consolidation among our competitors and third parties upon whom we rely could lead to changes in the competitive landscape, capabilities, and strategic priorities among potential service providers, which could have an adverse effect on our business and operations.

If we lose key personnel or are unable to attract and retain necessary talent, we may be unable to develop or commercialize our products under development.

We are highly dependent on our key technical and scientific personnel, who possess unique knowledge and skills related to our research and technology. If we were to lose the services of these individuals, we may be unable to readily find suitable replacements with comparable knowledge and the experience necessary to advance the research and development of our products. Because of the unique talents and experience of many of our scientific and technical staff, competition for our personnel is intense. The loss of key personnel or our inability to hire and retain personnel who have the required expertise and skills could have a material adverse effect on our research and development efforts, our business, and our ability to secure additional required financing.

Our business and operations would suffer in the event of system failures.

We utilize information technology systems and networks to process, transmit and store electronic information in connection with our business activities. As use of digital technologies has increased, cyber incidents, including deliberate attacks and attempts to gain unauthorized access to computer systems and networks, have increased in frequency and sophistication. These threats pose a risk to the security of our systems and networks and the confidentiality, availability and integrity of our data. There can be no assurance that we will be successful in preventing cyber-attacks or successful in mitigating their efforts.

Despite the implementation of security measures, our internal computer systems and those of our contractors and consultants are vulnerable to damage from such cyber-attacks, including computer viruses, unauthorized access, natural disasters, terrorism, war and telecommunication and electrical failures. Such an event could cause interruption of our operations. For example, the loss of data from completed field tests for our yield traits could result in delays in our regulatory approval efforts and significantly increase our costs. To the extent that any disruption or security breach were to result in a loss of or damage to our data, or inappropriate disclosure of confidential or proprietary information, we could suffer reputational harm or face litigation, or adverse regulatory action and the development of our product candidates could be delayed.

Risks Relating to Intellectual Property

Patent protection for our technologies is both important and uncertain.

Our commercial success may depend in part on our obtaining and maintaining patent protection for our technologies in the United States and other jurisdictions, as well as successfully enforcing and defending this intellectual property against third-party challenges. If we are not able to obtain or defend patent protection for our technologies, then we will not be able to exclude competitors from developing or marketing such technologies, and this could negatively impact our ability to generate sufficient revenues or profits from product sales and/or licensing to justify the cost of development of our technologies and to achieve or maintain profitability. Our currently issued patents relate mainly to our historical business, and have expiration dates ranging from 2020 through 2030. New outstanding patent applications owned by or licensed to us relating to crop yield improvements have filing dates ranging from 2013 through 2019 including the recently filed new patent application on a breakthrough technology for producing PHA biomaterials in crops. This patent would have an expiration date in 2039 if granted, however, we may not be able to get sufficiently broad claims to cover the new invention.

Our patent position involves complex legal and factual questions. Accordingly, we cannot predict the breadth of claims that may be allowed or enforced in our patents or in third-party patents. Patents may not be issued for any pending or future pending patent applications owned by or licensed to us, and claims allowed under any issued patent or future issued patent owned or licensed by us may not be valid or sufficiently broad to protect our technologies. Moreover, we may be unable to protect certain of our intellectual property in the United States or in foreign countries. Foreign jurisdictions may not afford the same protections as U.S. law, and we cannot ensure that foreign patent applications will have the same scope as the U.S. patents. There will be many countries in which we will choose not to file or maintain patents because of the costs involved. Competitors may also design around our patents or develop competing technologies.

Additionally, any issued patents owned by or licensed to us now or in the future may be challenged, invalidated, or circumvented. We could incur substantial costs to bring suits or other proceedings in which we may assert or defend our patent rights or challenge the patent rights of third parties. An unfavorable outcome of any such litigation could have a material adverse effect on our business and results of operations.

Third parties may claim that we infringe their intellectual property, and we could suffer significant litigation or licensing expense as a result.

Various U.S. and foreign issued patents and pending patent applications owned by third parties exist in areas relevant to our products and processes. We could incur substantial costs to challenge third-party patents. If third parties assert claims against us or our customers alleging infringement of their patents or other intellectual property rights, we could incur substantial costs and diversion of management resources in defending these claims, and the defense of these claims could have a material adverse effect on our business. In addition, if we are unsuccessful in defending against these claims, these third parties may be awarded substantial damages, as well as injunctive or other equitable relief against us, which could effectively block our ability to make, use, sell, distribute, or market our technologies and services based on our technologies in the United States or abroad. Alternatively, we may seek licenses to such third-party intellectual property. However, we may be unable to obtain these licenses on acceptable terms, if at all. Our failure to obtain the necessary licenses or other rights could prevent the sale, manufacture, or distribution of some of our products based on our technologies and, therefore, could have a material adverse effect on our business.

Portions of our crop science technology are owned by or subject to retained rights of third parties.

We have licensed and optioned from academic institutions certain patent rights that may be necessary or important to the development and commercialization of our crop science technology. These licenses and options may not provide exclusive rights to use such intellectual property in all fields of use in which we may wish to develop or commercialize our technology. If we fail to timely exercise our option rights and/or we are unable to negotiate license agreements for optioned patent rights on acceptable terms, the academic institutions may offer such patent rights to third parties. If we fail to comply with our obligations under these license agreements, or if we are subject to a bankruptcy or insolvency proceeding, the licensor may have the right to terminate the license. In some circumstances, we may not have the right to control the preparation, filing and prosecution of licensed patent applications or the maintenance of the licensed patents. Therefore, we cannot be certain that these patents and applications will be prosecuted, maintained and enforced in a manner consistent with the best interests of our business. Furthermore, the research resulting in certain of our licensed and optioned patent rights was funded by the U.S. government. As a result, the government may have certain rights to such patent rights and technology.

We may not be successful in obtaining necessary rights to additional technologies for the development of our products through acquisitions and in-licenses.

We may be unable to acquire or in-license additional technologies from third parties that we decide we need in order to develop our business. A number of more established companies may also pursue strategies to license or acquire crop science technologies that we may consider attractive. These established companies may have a competitive advantage over us due to their size, cash resources and greater development and commercialization capabilities. Any failure on our part to reach an agreement for any applicable intellectual property could result in a third party acquiring the related rights and thereby harm our business.

In addition, companies that perceive us to be a competitor may be unwilling to assign or license rights to us. We also may be unable to license or acquire relevant crop science technologies on terms that would allow us to make an appropriate return on our investment.

We expect that competition for acquiring and in-licensing crop science technologies that are attractive to us may increase in the future, which may mean fewer suitable opportunities for us as well as higher acquisition or licensing costs. If we are unable to successfully obtain rights to suitable crop science technologies on reasonable terms, or at all, our business and financial condition could suffer.

Our license agreements include royalty payments that we are required to make to third parties.

We are party to license agreements that require us to remit royalty payments and other payments related to our licensed intellectual property. Under our in-license agreements, we may pay upfront fees and milestone payments and be subject to future royalties. We cannot precisely predict the amount, if any, or timing of royalties we may owe in the future. Furthermore, we may enter into additional license agreements in the future, which may also include royalty, milestone and other payments.

The intellectual property landscape around genome editing technology, such as CRISPR, is highly dynamic and uncertain, and any resolution of this uncertainty could have a material adverse effect on our business.

The field of genome editing, especially in the area of CRISPR technology, is still in its infancy, and no products using this technology have reached the market. In 2018, we entered into a non-exclusive research license agreement jointly with the Broad Institute of MIT and Harvard and Pioneer, part of Corteva Agriscience™, Agriculture Division of DowDuPont Inc., for the use of CRISPR-Cas9 genome-editing technology for crops in order to demonstrate the utility of our yield trait genes in this field. The joint license covers intellectual property consisting of approximately 48 patents and patent applications on CRISPR-Cas9 technology controlled by the Broad Institute and Corteva Agriscience. Under the agreement, we have the option to renew the license on an annual basis and the right, subject to specified conditions, to convert the research license to a commercial license in the future, although there can be no assurance that we will be able to secure such commercial license on acceptable terms. CRISPR technology is uniquely suited to agricultural applications as it enables precise changes to plant DNA without the use of foreign DNA to incorporate new traits. Plants developed using CRISPR genome-editing technology have the potential to be considered not regulated by USDA-APHIS under 7 CFR part 340 for development and commercialization in the U.S., which could result in shorter developmental timelines and lower costs associated with commercialization of new traits in the U.S. as compared to regulated crops. Due to the intense research and development that is taking place by several companies, including us and our competitors, in this field, the intellectual property landscape is in flux, and it may remain uncertain for the coming years. There has been, and may continue to be, significant intellectual property related litigation and proceedings relating to this area in the future. If it is later determined that the patent rights using the CRISPR technology that we obtained under license are invalid or owned by other parties, this could have a material adverse effect on our business.

We rely in part on trade secrets to protect our technology, and our failure to obtain or maintain trade secret protection could harm our business.

We rely on trade secrets to protect some of our technology and proprietary information, especially where we believe patent protection is not appropriate or obtainable as is the case for our GRAIN trait gene discovery platform. However, trade secrets are difficult to protect. Litigating a claim that a third party had illegally obtained and was using our trade secrets would be expensive and time consuming, and the outcome would be unpredictable. Moreover, if our competitors independently develop similar knowledge, methods and know-how, it will be difficult for us to enforce our rights and our business could be harmed.

Risks Relating to Owning our Common Stock

You will be unable to exercise the warrants and they may have no value under certain circumstances.

We will not have authorized shares available to permit exercise of the warrants and such warrants will not be exercisable if we do not obtain stockholder approval to increase the number of authorized shares of common stock in an amount sufficient to permit exercise in full of the warrants. If we are unable to obtain such approval, the warrants will have no value.

Raising additional funds may cause dilution to our existing stockholders, restrict our operations or require us to relinquish rights to our technologies.

Execution of our business plan requires additional financing. If we raise additional funds through equity offerings or offerings of equity-linked securities, including warrants or convertible debt securities, we expect that our existing stockholders will experience significant dilution, and the terms of such securities may include liquidation or other preferences that adversely affect your rights as a stockholder. Debt financing, if available, may subject us to restrictive covenants that could limit our flexibility in conducting future business activities, including covenants limiting or restricting our ability to incur additional debt, dispose of assets or make capital expenditures. We may also incur ongoing interest expense and be required to grant a security interest in our assets in connection with any debt issuance. If we raise additional funds through strategic partnerships or licensing agreements with third parties, we may have to relinquish valuable rights to our technologies or grant licenses on terms that are not favorable to us.

Trading volume in our stock can fluctuate and an active trading market for our common stock may not be available on a consistent basis to provide stockholders with adequate liquidity. Our stock price may be extremely volatile, and our stockholders could lose a significant part of their investment.

The public trading price for our common stock will be affected by a number of factors, including:


•	any change in the status of our Nasdaq listing;


•	the need for near-term financing to continue operations;


•	reported progress in our efforts to develop crop related technologies, relative to investor expectations;


•	changes in earnings estimates, investors’ perceptions, recommendations by securities analysts or our failure to achieve analysts’ earnings estimates;


•	quarterly variations in our or our competitors’ results of operations;


•	general market conditions and other factors unrelated to our operating performance or the operating performance of our competitors;


•	future issuances and/or sales of our securities;


•	announcements or the absence of announcements by us, or our competitors, regarding acquisitions, new products, regulatory developments, significant contracts, commercial relationships or capital commitments;


•	commencement of, or involvement in, litigation;


•	any major change in our board of directors or management;


•	changes in governmental regulations or in the status of our regulatory approvals;


•	announcements related to patents issued to us or our competitors and to litigation involving our intellectual property;


•	a lack of, or limited, or negative industry or security analyst coverage;


•	uncertainty regarding our ability to secure additional cash resources with which to operate our business;


•	a decision by our significant stockholders to increase or decrease their holdings in our common stock;


•	short-selling or similar activities by third parties; and


•	other factors described elsewhere in these risk factors.

As a result of these factors, our stockholders may not be able to resell their shares at, or above, their purchase price. In addition, the stock prices of many technology companies have experienced wide fluctuations that have often been unrelated to the operating performance of those companies. Any negative change in the public’s perception of the prospects of industrial or agricultural biotechnology companies could depress our stock price regardless of our results of operations. These factors may have a material adverse effect on the market price and liquidity of our common stock and affect our ability to obtain required financing.

Provisions in our certificate of incorporation and by-laws and Delaware law might discourage, delay or prevent a change of control of our company or changes in our management and, therefore, depress the trading price of our common stock.

Provisions of our certificate of incorporation and by-laws and Delaware law may discourage, delay or prevent a merger, acquisition or other change in control that stockholders may consider favorable, including transactions in which our stockholders might otherwise receive a premium for their shares of our common stock. These provisions may also prevent or frustrate attempts by our stockholders to replace or remove our management.

In addition, Section 203 of the Delaware General Corporation Law ("DGCL") prohibits a publicly-held Delaware corporation from engaging in a business combination with an interested stockholder, which generally refers to a person which together with its affiliates owns, or within the last three years has owned, 15 percent or more of our voting stock, for a period of three years after the date of the transaction in which the person became an interested stockholder, unless the business combination is approved in a prescribed manner.

The existence of the foregoing provisions and anti-takeover measures could limit the price that investors might be willing to pay in the future for shares of our common stock. They could also deter potential acquirers of our company, thereby reducing the likelihood that our stockholders could receive a premium for their common stock in an acquisition.

Concentration of ownership among our officers, directors and principal stockholders may prevent other stockholders from influencing significant corporate decisions and depress our stock price.

Based on the number of shares outstanding as of November 7, 2019, our officers, directors and stockholders who hold at least 5% of our stock beneficially own a combined total of approximately 45.7 percent of our outstanding common stock, including shares of common stock subject to stock options and warrants that are currently exercisable or are exercisable within 60 days after November 7, 2019. If these officers, directors, and principal stockholders or a group of our principal stockholders act together, they will be able to exert a significant degree of influence over our management and affairs and control matters requiring stockholder approval, including the election of directors and approval of mergers, business combinations or other significant transactions. The interests of one or more of these stockholders may not always coincide with our interests or the interests of other stockholders. For instance, officers, directors, and principal stockholders, acting together, could cause us to enter into transactions or agreements that we would not otherwise consider. Similarly, this concentration of ownership may have the effect of delaying or preventing a change in control of our company otherwise favored by our other stockholders. As of November 7, 2019, Jack W. Schuler (and his related entities) beneficially owned approximately 40.1 percent of our common stock. Following the approval of the Charter Amendment and the issuance of shares in the concurrent private placement, Mr. Schuler (and his related entities) will beneficially own well over a majority of our common stock. To the extent that this or any other significant stockholders oppose any proposal put forth for stockholder approval by our board of directors, they control a sufficient percentage of our outstanding shares to cause such proposal to either fail or be very difficult to achieve without their support. This, in turn, could have a negative effect on the market price of our common stock. It could also prevent our stockholders from realizing a premium over the market price for their shares of common stock. The concentration of ownership also may contribute to the low trading volume and volatility of our common stock.

The comprehensive tax reform bill known as the Tax Cuts and Jobs Act could adversely affect our business and financial results.

On December 22, 2017, President Trump signed into law the Tax Cuts and Jobs Act of 2017, or ("TCJA"), that significantly reformed the Code. The TCJA, among other things, includes changes to U.S. federal tax rates, imposes significant additional limitations on the deductibility of interest and net operating loss carryforwards, allows for the expensing of capital expenditures, and puts into effect the migration from a "worldwide" system of taxation to a territorial system. Our net deferred tax assets and liabilities have been revalued at the newly enacted U.S. corporate rate as of December 31, 2018. We continue to examine the impact this tax reform legislation may have on our business and we urge our stockholders to consult with their legal and tax advisors with respect to such legislation and the potential tax consequences of investing in our common stock.

In addition, the net proceeds to us from the concurrent private placement will be approximately $4.2 million. We will pay a 3% fee in connection with a portion of the units to be sold in the concurrent private placement, and will pay an 8% fee in connection with the remainder of those units. We estimate that the aggregate net proceeds to us from the offering and concurrent private placement will be approximately $8.6 million (or approximately $9.3 million if the underwriters exercise their over-allotment option in full). We will not receive any additional proceeds from any future conversions of the Series A Preferred Stock or the Series B Preferred Stock. We will only receive additional proceeds from the exercise of the warrants issuable in connection with this offering if the warrants are exercised and the holders of such warrants pay the exercise price in cash upon such exercise and do not utilize the cashless exercise provision of the warrants.

We intend to use net proceeds from this offering and the concurrent private placement for working capital and general corporate purposes. We have not yet determined the amount of net proceeds to be used specifically for any particular purpose or the timing of these expenditures. Accordingly, our management will have significant discretion and flexibility in applying the net proceeds from the sale of these securities.

BUSINESS

Overview

Yield10 Bioscience, Inc. is an agricultural bioscience company which uses its "Trait Factory" to develop high value seed traits for the agriculture and food industries. Specifically, Yield10 plans to efficiently develop superior gene traits for the major grain crops including corn, soybean, canola, wheat and rice that will enable step-change increases in crop yield of at least 10-20 percent. While maintaining our focus on the development of novel yield traits for key grain crops based on a licensing model, we have recently begun to execute the second part of our strategy which is to develop independent business opportunities for Yield10 in the specialty oils and niche crop product space using the oilseed Camelina. The target of this effort is sustainable business solutions to support agriculture, sustainable global food production and other specialty applications. Yield10 brings a unique history, skill set and tools, captured in its GRAIN platform, for developing advanced crop traits and increasing the concentration of specific biochemicals of commercial interest in crops. Our plan is to use GRAIN to develop a source of revenue from funded research and development collaborations for traits, products and crops not being directly pursued internally. We are currently engaged in a range of discussions with third parties with respect to different crops, traits and products in the feed, food and pharmaceutical sectors.

We are currently progressing several novel yield gene traits in our pipeline in the major North American row crops canola, soybean and corn, and the niche crop Camelina, among others. Camelina is an oilseed crop similar to canola, with significant upside potential as a production platform for edible oils and PHA biomaterials. Our approach is to focus internal resources on progressing our traits through development and field trials in Camelina and canola while leveraging third party resources to progress our traits in soybean and corn while retaining control of our intellectual property. Over the last three years, we have evaluated certain of our traits in greenhouse studies and field tests conducted in the United States and Canada. We currently have non-exclusive research license agreements in place with the Crop Science division of Bayer AG, for the evaluation of our C3003 and C3004 traits in soybean and with Forage Genetics International, LLC, a division of Land O’Lakes, Inc. for the evaluation of five yield traits in forage sorghum. Our business strategy is to progress our traits into field tests to generate validating yield data. We have progressed our evaluation of C3003 in field tests with Camelina and canola and we are planning to expand our field tests with more C3003 canola events. We plan to leverage data that we generate to support the performance of our traits in key crops to establish collaborations or to sign licenses to the traits with major agricultural companies in order to generate revenue. Yield10 Bioscience is headquartered in Woburn, Massachusetts and has an oilseed development Center of Excellence in Saskatoon, Saskatchewan, Canada.

Crop yield is determined by the efficiency by which crops fix carbon dioxide from the air through photosynthesis and convert that fixed carbon through carbon metabolism during the growing season into harvestable grain or biomass. Yield10 brings unique capabilities and experience in advanced metabolic engineering and systems biology to optimize photosynthesis and carbon efficiency in crops to increase grain or biomass yield. These capabilities were developed based on sustained investment over many years when the Company was named Metabolix. As Metabolix, the Company solved complex biological problems in the industrial/synthetic biology space to produce bioplastics. By 2012, the Company had

begun work to increase photosynthesis in crops as part of those activities, which led to the creation in 2015 of the current Yield10 business focused on crop yield. In mid-2016 we sold our bioplastics assets to focus on our agricultural innovations and the Company was rebranded as Yield10 Bioscience in January 2017.

Exciting new genetic engineering technologies like the CRISPR technology and other approaches to genome editing hold promise to accelerate the deployment of novel traits into commercial crops. This method of making insertions or deletions of DNA into plants without the use of foreign DNA has been described as “precision breeding.” We signed a research license, with rights to convert to a commercial license, to CRISPR/Cas-9 technology in 2018 to support our genome editing program. We have taken two genome edited traits designed to boost oil content in oilseed crops through the USDA-APHIS “Am I Regulated?” petitioning process and have confirmed that the agency does not consider two of our lines to be regulated pursuant to 7 CFR part 340, clearing the way to conduct field tests in the United States. Genome editing technology as well as the streamlined regulatory process supported by USDA-APHIS for certain types of plant traits may enable agricultural innovators such as Yield10 to deploy and field test new traits more quickly, potentially resulting in a shorter path to market and reduced costs as compared to the more highly regulated path required for traditional biotechnology-derived traits.

_____________



(1)	C3003 and C3011 consist of microbial genes and are likely to be subject to regulation by USDA-APHIS.

(2)	These traits are accessible using genome editing or other methods that do not result in the insertion of non-plant DNA. These approaches may be deemed not to be regulated by USDA-APHIS pursuant to 7CFR part 340 based on recent filings by us and other groups.

(3)	Traits in this area were developed in our T3 platform and all are potentially deployable through approaches which may be not-regulated by USDA-APHIS pursuant to 7 CFR part 340.

(4)	USDA-APHIS does not consider these lines submitted by Yield10 to be regulated pursuant to 7 CFR part 340. Commercial plant or plant lines or plant products derived from these lines may be regulated by the FDA or EPA.

foundation of Yield10’s trait development process. We refer to this trait development process as the “Trait Factory.” The Trait Factory encompasses discovery of gene targets using our GRAIN platform (which stands for Gene Ranking Artificial Intelligence Network), genetic engineering of crops using traditional approaches or genome editing to modify those targets and generation of field data with the engineered crops. Performance and molecular data from the engineered crops are then fed back into the GRAIN system to enable refinement of specific gene targets and the identification of new trait gene targets. Modified crops with improved performance enter our development pipeline and progress on the regulated or non-regulated path to market depending on how the plants are genetically engineered. GRAIN is a powerful new tool developed primarily to focus on Yield10 trait targets including performance traits for major row crops including corn, soybean, and canola as well as our niche product opportunities based on our Camelina platform. We believe we may also be able to generate a revenue stream by providing access to our GRAIN platform to third parties interested in other trait targets and/or crops Yield10 is not pursuing.

As we continue to develop the GRAIN platform, key elements of this system have proven effective and have enabled Yield10 to produce several promising crop yield traits in our development pipeline. Yield10 has achieved and published in peer reviewed journals scientific data from growth chamber and greenhouse studies showing that significant improvements to crop yield are possible. We have achieved these results by improving fundamental crop yield through enhanced photosynthetic carbon capture and increased carbon utilization efficiency to increase seed yield. Examples of these traits and their impact on crop yield are shown below. The C3005 trait results required a complex combination of microbial genes to enhance carbon fixation during seed development and serves to highlight the power of our advanced metabolic engineering/systems biology approach. Results we have obtained based on preliminary testing of our C3003 and C3004 traits as well as our C4000 series traits support our plans to test and develop these traits in major row crops.

Examples of our traits and their impact on crop yield in growth chamber and greenhouse studies

C3003/C3004 traits: 23% - 65% increase in seed yield in oilseed crops (Camelina)

C3006 advanced synthetic biology trait: 128% increase in oilseed yield (Camelina)

C4001, C4003 traits: 70% increase in photosynthesis, 150% increase in biomass (switchgrass)

Yield10 has a pipeline of more than 10 novel yield traits in research and development and we expect to generate several proof points for our traits in various crops over the next two years. We are developing our lead yield trait C3003 in canola and recently completed its second year of field tests in Canada. We continued field tests in 2019 as we advance the trait towards commercial development by developing additional commercial canola lines with the trait and expanding field testing. We plan to undertake our first field testing of C3004 in our Camelina platform in 2019 and are working to deploy and test this promising trait in canola, soybean and corn in the future. We have proven capabilities with genome editing using the CRISPR/Cas9 system and USDA-APHIS has determined that single and multiple genome edited lines of Camelina designed to increase oil content are not considered to be regulated by the agency under 7 CFR part 340. We plan to field test these plant lines and use the data to optimize the deployment of these traits to boost oil content in canola and potentially soybean. We recently successfully edited C3007, a novel target gene for increasing oil content, in canola and these plants are now progressing through our development pipeline. We plan to continue to progress initial development and testing of multiple traits in wheat and rice. Our approach is to engineer rice and wheat plants with our gene regulator traits to increase photosynthesis and grain yield and use those plants as a source of data to generate new gene targets for genome editing. Yield10 has no plans to field test or develop wheat or rice using traditional genetic engineering technologies. We anticipate that data generated on our traits will enable us to establish revenue generating collaborations in the future for the development and commercialization of our novel yield traits in commercial crops.

We are building a portfolio of intellectual property around our crop yield technology and traits. As of September 30, 2019, we owned or held exclusive rights to 23 patents or pending patent applications worldwide related to advanced technologies for increasing yield in crops. Our portfolio of patent applications includes plant science technologies we have in-licensed globally and exclusively from the University of Massachusetts and North Carolina State University related to the yield trait gene C3003 and other advanced technologies based on advanced metabolic engineering methods to improve carbon capture and selectively control carbon partitioning in plants. Our portfolio of patent applications also includes advanced technologies for increasing oil content in oilseed crops that we in-licensed globally and exclusively from the University of Missouri in 2018 and 2019 related to the yield trait genes C3007, C3010 and C3012. We also recently filed a new patent application on a breakthrough technology for producing PHA biomaterials in oilseeds which offers the potential for very low cost production of a specialty crop with applications in water treatment and plastics replacement.

The Unmet Need: Global Population Growth Outpacing Anticipated Global Food Supply

Yield10 is targeting a critical unmet need in agriculture based on the future disconnect between agricultural supply and the growing global population. According to a United Nations study, the global population is expected to exceed 9.6 billion people by 2050 and therefore there is a need to increase global food production including in grains, protein, dairy and edible oils to meet this demand. This will need to be achieved in the face of increased pressure on land and water resources in addition to increasingly variable weather patterns. Solving this problem is a major global challenge requiring new crop innovation and technologies to fundamentally enhance crop productivity.

The Yield Gap

According to several studies described in an article published in the Public Library of Science in 2013, crop yields may no longer be increasing in different regions of the globe, and current rates of crop yield increase based on traditional plant breeding approaches are expected to fall significantly behind the levels needed to meet the demand for global food production. The researchers found that the top four global crops—maize (corn), rice, wheat and soybean—are currently witnessing average yield improvements of only between 0.9 to 1.6 percent per year, far slower than the required rates to double their production by 2050 solely from incremental yield gains. At these rates, global production of maize, rice, wheat and soybean crops may be required to increase by about 67 percent, 42 percent, 38 percent and 55 percent, respectively, by 2050, in order to meet the anticipated increase in demand for food production caused by population growth. For corn and soybean, the benefits of currently available biotechnology traits were already factored into the data cited in the studies referenced above. The yield increases needed to meet the demands of the growing global population show that a significant “yield gap” exists for each of the crops evaluated in the study.

Yield10 is focused on addressing the yield gap for major crops by utilizing modern biotechnology strategies, including metabolic engineering (synthetic biology approaches) to “build better plants,” by using our Trait Factory to optimize photosynthesis and carbon efficiency in crops to increase grain or biomass yield. Enhancement of the photosynthetic capacity of major crops is fundamentally important to crop science and an essential first step to increase the seed and/or biomass yield of plants and, therefore, food production. We have been working in the area of increasing photosynthetic carbon capture and crop yield technologies since 2012 and we have identified several potentially promising genes for increasing yield or improving crop performance.

Health and Wellness, Food Safety and Sustainability

At the same time, with the increasing focus on health and wellness, food safety and sustainability in developed countries, we anticipate a rise in demand for new varieties of food and food ingredients with improved nutritional properties. Further, concerns about food safety have led to the concept of "seed to plate," with a focus on stringent quality control along the entire value chain. If this concept takes hold with consumers, it is likely to require identity preservation from seed to harvest and involve contract farming. This concept is currently being implemented in agricultural biotechnology, in both canola and soybean which have been modified to alter the composition of the oil produced. High oleic canola and soybean oils are being marketed as "healthier" where the value driver is the ability to make marketing claims directly to the consumer. Camelina oil has also recently been shown in clinical studies to be more effective than fish oil for controlling LDL cholesterol indicating potential use in reducing heart disease. Consumer demand to preserve the identity of specialty ingredients is expected to rise, and we believe that Yield10's crop yield technologies and crop gene editing targets could be useful in this emerging field. Yield10 believes that these types of small acreage specialty crops have the potential for a broader range of future partnering opportunities along the entire value chain. Camelina also has considerable potential as a cover crop to reduce soil erosion and nutrient run-off from land used for row crop production. Production of PHA biomaterials in Camelina could provide economic returns for farmers to justify large acreage adoption and enable the low-cost production this product for new markets including water treatment and plastics replacement applications.

Business Strategy

Our goal is to build a successful agricultural biotechnology company centered on demonstrating and capturing the value of our traits and technologies based on three potential revenue streams. In major food and feed crops for licensing to established agricultural companies and building other revenue generating business from our new niche crop opportunities we have begun developing based on our patent protected technologies. These potential revenue streams consist of:


•	Licensing of our yield and performance traits for use in major row crops;


•	Product sales revenue from niche products produced in our Camelina platform and other oilseeds; and


•	R&D revenue for access to our GRAIN trait gene discovery platform.

We have identified and are evaluating novel yield trait genes in our Trait Factory to help address the growing global yield gap in food and feed crops. As the primary driver of financial returns each season, crop yield is the key decision variable for farmers in making seed buying decisions, and as a result, is critical to the seed industry. Improvements in yield to the levels targeted by Yield10, for example 10-20 percent increases, would be expected to generate significant value to the seed and crop industry. For example, Yield10 is targeting an approximately 10-20 percent increase in canola and soybean yields, which, if successfully deployed across North American acreage, could result in annual incremental crop value of up to $10 billion. By ultimately increasing the output of major food and feed crops and potentially reducing strains on scarce natural resources, we believe that Yield10’s technologies will also contribute to addressing global food security.

Recognizing the highly concentrated nature of the seed business, the prevalence of cross-licensing of traits, and the need to stack multiple crop traits in elite seed germplasm to provide the best options for farmers for large acreage commodity crops, Yield10 does not expect to become an integrated seed company. The current major seed companies dominate the biotech crop space based largely on the early technology innovations that resulted in herbicide and pest resistance traits and have a very successful operating track record in the sector. Yield10 plans to develop yield traits that enable farmers to increase their revenue and secure a share of that added value. To do this Yield10 plans to license our trait innovations to the major agricultural companies so that they can be deployed in elite seed varieties. The incremental value sharing model is well established in the seed sector. Therefore, rather than replicating the downstream elements of these operations and developing our own regulatory, crop breeding or seed production capabilities, we intend to seek industry collaborations and partnerships to leverage these existing core competencies of the current seed industry. Yield10 will focus on its core competency, which is breakthrough science and technology innovation applied to the seed sector.

The type of collaborations and partnerships we seek will depend on the specific anticipated path to market for the crop. For large acreage biotech crops including canola, soybean and corn, we plan to develop proof points for our yield traits as a basis for licensing to major agricultural companies with a focus on capturing downstream value. By developing gene traits that enable the farmer to increase revenue, Yield10 believes that it can secure a share of that increased revenue in much the same way Uber generates revenue by enabling private car owners to operate in the taxi business. According to industry estimates, the timeline from discovery to full commercialization of a biotech trait in a commodity crop can be up to 13 years at a cost of up to $130 million. Our C3003 yield trait is an algal gene, and we believe that it will be regulated as a biotech trait. As we are in the construct optimization/event selection stage, we believe that we are approximately half way along the anticipated development timeline for C3003 in canola. Our strategy is to make it attractive for major agricultural companies to invest financial and technical resources to introduce our traits into their elite germplasm for event selection and evaluation. In 2017, we signed a non-exclusive research license with the Crop Science division of Bayer AG ("Bayer") (formerly Monsanto Company), to test C3003 and C3004 in soybean. In 2019, the license was expanded to cover a new discovery and intellectual property related to C3004. Similarly, in 2018 we signed a non-exclusive research license with Forage Genetics International LLC, a division of Land O'Lakes, Inc. ("Forage Genetics"), to test a series of traits in forage sorghum. We may sign additional non-exclusive research licenses on a crop by crop basis in the future, allowing the licensees to invest their resources in progressing the trait. Our focus is on securing a share of the upside value of our traits when we finalize the economic terms of license agreements at the point where the value of the trait is well understood.

For small acreage specialty oil crops, we believe we can leverage our Camelina platform, seed yield and oil content traits to add value to the development of specialty oils focused on human nutrition and aquaculture feed markets. These crops can cost more to produce because of the unique supply chain needed when identity preservation from seed planting to final product is desired. In this area, there may be opportunities for establishing partnerships and license agreements with consumer facing companies in the food and feed sector. Our high oil content traits developed through genome editing may have shorter timelines to commercialization (3-6 years) if deployed in specialty oil crops. We are at an early stage of developing our strategy in this area but believe it may have considerable potential for Yield10.

We believe that the production of PHA biomaterials in Camelina could provide economic returns for farmers to justify large acreage adoption and enable the low-cost production of this product for new markets including water treatment and plastics replacement. We believe crop based production will enable an advantageous cost structure thereby eliminating one of the remaining significant barriers to entry for broad adoption of these biomaterials. In water treatment the PHA biomaterial acts as a growth substrate and energy source for denitrifying bacteria which convert nitrate, a primary cause of water pollution and algal growth to nitrogen gas which returns to the air. This application is technically

straight-forward, requiring only the production and shipment of PHA biomaterials in pellet form. Yield10 is in the early stages of developing a revenue generating business model for this opportunity.

PHA biomaterials are also widely useful for functionally replacing petroleum-based plastics in a wide range of packaging applications. The plastics industry, which produces more than 350 million tons of material per year globally, is facing intensive scrutiny due to the failures in plastics recycling and increasing plastic waste in the environment. As natural biomaterials, PHAs fully degrade over time in the environment yet have excellent shelf life in use. We estimate that PHA biomaterials can be produced at very low cost in oilseeds based on our newly patented technology. When we made the transition to the Yield10 business we divested our fermentation-based PHA bioplastics assets and related application technology, based on the microbial fermentation platform but retained the patents and field of PHA production in engineered crops. Yield10 plans to produce resin-grade PHA biomaterial for supply to the plastics sector.

Yield10 plans to build on its core strengths bringing new technology approaches to exploit an innovation gap in the agricultural biotechnology space that exists due to reduced investment in basic research and development resulting from the ongoing consolidation and restructuring in the agricultural sector. Yield10’s mission is to translate and optimize our step-change yield trait innovations in six major food and feed crops and demonstrate their economic value to farmers and seed companies. We intend to create high-value assets in the form of proprietary yield trait gene technologies and to de-risk these assets by progressing them along the path to commercial development with increasingly larger scale field tests and multi-site field trials in major crops. We are currently deploying our yield trait genes into canola, soybean, rice, wheat and corn, by designing and progressing genetically engineered events that we believe to be suitable for the applicable regulatory approval processes and which can be readily bred into the industry’s elite crop lines by plant breeding. We expect the customers for Yield10’s innovations to be the large and mid-size agricultural companies that would either license or acquire rights to Yield10’s yield trait genes and incorporate them into their proprietary commercial crop lines for subsequent commercialization.

We are focused on identifying and developing technologies that will enable us to produce step-change improvements to crop yield.

Yield10 is targeting a critical unmet need in agriculture based on the anticipated disconnect between agricultural supply and the growing global population. Food production must be increased by over 70 percent in the next 35 years to feed the growing global population, which is expected to increase from 7 billion to more than 9.6 billion by 2050. Global climate change is also resulting in regional shifts to historical growing conditions. Given the projection for population growth, recent studies show a “yield gap” for major food and feed crops that cannot be addressed by incremental improvements to yield brought about by traditional plant breeding and existing biotech traits. Current biotech traits deployed in crops by the seed industry are based primarily on using microbial-sourced genes to impart yield protection through herbicide, pest, disease and even drought resistance, whereas Yield10 is focused on increasing fundamental crop yield through enhanced carbon capture and utilization.

Yield10 is focused on “building better plants” using the Trait Factory to optimize photosynthesis and carbon efficiency in crops to increase grain or biomass yield targeting step-change increases in the range of 10-20 percent in crop yield.

Our History

We have a significant track record and expertise in the metabolic engineering of microbes and have made significant progress translating this capability to plants.

As part of the legacy biopolymers and biobased chemicals business of our predecessor company Metabolix, our research team developed an advanced metabolic engineering capability to alter key biochemical pathways and redirect the flow of carbon metabolic intermediates in microbes resulting in the production of PHA, a natural biomaterial, at a level of more than 80 to 90 percent by weight of microbial cells that normally did not produce any PHA. In 1997, Metabolix initiated a crop science research program to produce PHA biomaterials in crops as a low cost production system. Historically, these efforts were focused on producing PHB, a microbial carbon storage biopolymer, in high concentration in the seeds of oilseed crops or in the leaves of biomass crops such as switchgrass. The PHB biomaterial is useful as a natural water treatment product and as a replacement for petroleum-based plastics.

As we made progress on producing PHB in plants, we learned that basic carbon supply from photosynthesis was a bottleneck. To address this carbon shortfall, in 2012 we began developing new metabolic engineering and bioinformatics approaches to enhancing basic crop photosynthetic carbon capture. Discoveries from these two approaches became the foundation of our GRAIN crop trait discovery platform. We also began building intellectual property on novel yield trait

gene technologies discovered in these programs and realized that our experience in re-engineering the flow of carbon in microorganisms could be applied to building better plants. Photosynthesis is the most important biological process responsible for global food production. Improving the photosynthetic capacity of plants is an essential first step to increase seed and/or biomass yield and, therefore, food production. We must develop plants which on a per acre basis during the growing season fix more carbon and ultimately target that additional fixed carbon to seed or biomass.

Our Approach

We have assembled a pipeline of crop yield traits for development that are applicable to major commercial crops.

Our unique approach to crop yield trait discovery utilizing our GRAIN platform, which integrates advanced metabolic engineering concepts to address critical bottlenecks in carbon metabolism, has enabled us to discover a series of yield genes with potential use for producing step-change improvements in crop yield. Through our research and early development efforts we have identified and begun characterizing our C3000 and C4000 series of traits. To initially characterize the potential yield trait genes, we test many of our yield trait candidates using our Camelina platform. As a yield trait innovator, our objective is to identify novel yield traits that act at a fundamental level in crop metabolism to provide the potential for broad deployment of our traits across multiple crop types. Following our early work with these trait genes, we focus on deploying the traits for evaluation across a range of crops including canola, soybean, corn, rice, wheat, each of which are crops of high commercial interest in North America. For crops where Yield10 is not directly conducting research and development activities, we are open to licensing arrangements like the agreement we have in place with Forage Genetics for evaluation of five of our traits in forage sorghum. Our goal is to generate greenhouse and field test data that will support commercial development of the trait and enable us to form collaborations or enter into license agreements with major agricultural companies in order to incorporate our novel yield traits into their seed products. We believe that successfully launching new, high yielding seed to the market would result in higher economic benefit to growers, seed companies, and Yield10.

We believe our business model will allow us to capture value for our yield trait discoveries and provide a path to commercialization for important new yield traits for major crops.

Yield10 is working to advance our own developments as well as form business alliances to progress our traits through development, launch and commercialization. Our goal is to capture an attractive share of the added economic value resulting from the deployment of our trait genes and technologies in key crops. We are currently working on the development and deployment of our trait genes into several crops, an approach facilitated by the expiration of much of the early foundation patents in the agricultural biotechnology sector, and one of our key objectives in that regard is to demonstrate commercial proof points through field tests and multi-site field trials. Yield10 opportunities and business models for value capture include partnering or licensing with established agricultural industry companies. Key to our strategy is to retain, where practical, control of timelines and maximize, where possible, the opportunity for value creation and optionality around future value realization strategies. In 2019, we are focused on identifying and signing additional research and development collaborations to accelerate commercial development of our promising yield traits.

We have signed non-exclusive research licenses for our novel yield traits with agriculture industry leaders.

In 2017 we granted a non-exclusive global research license to Bayer to evaluate our novel yield traits C3003 and C3004 in soybean. The license was expanded in 2019 to include a new discovery and intellectual property for C3004. Bayer is a leader in the development and commercialization of biotech-derived soybean seed. In 2018, we granted a research license with a similar structure to Forage Genetics, a leader in forage crops used for animal feed, to evaluate five traits in forage sorghum.

These licenses are intended to provide market leaders in their respective crops with an attractive opportunity to test our traits and develop data at their own expense. At any time during the term, they have the option to negotiate a broader agreement with us. At the same time, we have the right to sign licenses with other companies for these traits. This structure allows us the flexibility to expand the testing of our traits with investment by other companies and to potentially enter negotiations for development and commercial licenses when the value of our traits is better understood. In 2019, we plan to explore additional opportunities to expand the testing of our traits through similar arrangements with other companies.

We are focused on developing yield traits for use in canola, soybean and corn, major North American commercial crops.

Canola, soybean and corn represent the largest North American commercial crops with approximately 195 million combined acres. The majority of the crop acreage incorporates biotechnology traits for herbicide or pesticide resistance that are deployed in elite germplasm controlled by seed companies. Recent advances in crop yield have been based primarily on the use of biotechnology traits to protect yield by managing and/or allowing the plants to outcompete weeds. We are developing our traits to complement the biotechnology traits currently utilized in these major crops by focusing on our traits to increase the inherent seed yield of the plant. In 2018, we obtained promising field test results for second generation C3003 in canola and advanced work with the trait into the early commercial development phase where we will make and test additional elite events of the C3003 trait. Our development work with C3003 and other traits in the C3000 and C4000 series, some of which may be accessible using genome editing, is progressing in canola, soybean and corn. Canola is important as an edible oil for human consumption, while soybean and corn are grown in North America mainly as animal feed.

We are testing our yield traits in wheat and rice, important staple crops for human consumption.

Wheat and rice are important staple crops used primarily for human consumption. It is estimated that more than 900 million acres of rice and wheat are grown annually worldwide. Advances in seed yield for rice and wheat have occurred primarily through plant breeding for rice and hybridization and breeding for wheat. Genetically modified, or GM, traits based on biotechnology have not been broadly introduced into these crops. Seed sales to growers for these crops typically rely on regional, local organizations to distribute and sell seed and the market is extremely fragmented. To enable production of wheat and rice to meet future global demand, increases in yields will be required. The application of genome editing to precisely incorporate yield traits into these crops may represent a way to increase yield and establish consumer acceptance of the technology and seed product. We recently published promising results with members of our C4000 series of traits showing that deployment of these traits in switchgrass as a model crop resulted in significant increases in photosynthesis and biomass yield. We are testing C4000 series traits that may be accessible through genome editing as a strategy to produce increases in seed yield in wheat and rice. If we are successful identifying yield traits accessible through genome-editing that have potential to boost seed yield in rice and/or wheat, we are likely to seek partners for further development and commercialization in these food crops.

Our GRAIN platform provides us with a unique approach for discovering novel yield trait genes.

We have integrated advanced metabolic flux modeling capabilities with transcriptome network analysis to form the foundation of our GRAIN bioinformatics gene discovery platform. This discovery platform is the core of our Trait Factory. GRAIN takes both a bottom up approach based on the flow of electrons and carbon through essential metabolic processes and a top down approach based on transcriptome network analysis. In the case of crops, the levers to increase seed yield are the metabolic infrastructure through which carbon flows from photosynthesis to seed production and the gene regulators or transcription factors which control the various pathways. Over the last 20 years, the agricultural sector has generated vast numbers of data points. During this same period, there have been very few new crop traits produced. The purpose of GRAIN is to develop a system which can convert data sets into actionable gene targets to improve crop productivity. We have employed this approach to discover a range of potential yield trait genes.

We have identified promising potential yield targets which can be modified using genome editing. We believe that such targets may be subject to less regulatory complexity in the U.S. during development and along the path to commercialization and may provide opportunities for licensing.

Genome editing techniques, including CRISPR, which involve making small targeted changes to the DNA of a target organism, have been of interest to the agricultural biotechnology industry because this approach is believed to have the potential to significantly reduce development costs and regulatory timelines for crop trait development and market introduction. In 2018, we signed a non-exclusive research license for CRISPR/Cas-9 technology with the Broad Institute of MIT and Harvard and Pioneer, part of the Corteva Agriscience Agriculture Division of DowDuPont Inc.

Announcements from USDA-APHIS, including those made in 2018, indicate that the regulatory path for genome edited plants lines that do not contain any remaining foreign DNA (i.e. DNA sequences not from the plant being engineered) from the procedure used to edit the plant may not be subject to certain USDA-APHIS crop regulations in the U.S. See “Regulatory Requirements” section below. One of the potential implications of this regulatory approach in which edited plants are subject to fewer regulatory controls than traditional genetically modified plants may be to significantly decrease the timeline and cost of developing and bringing new traits to commercialization in the U.S. The challenge now

for the agricultural biotechnology sector will be to identify gene targets for genome editing that can generate economic value. This has opened the potential for Yield10 to exploit a second tier of novel traits addressable with genome editing.

Yield10 has identified, from its internal discovery platforms and in-licensed through academic collaborations, gene targets suitable for deployment in crops through genome editing. In the course of our work, we have introduced genes coding for new metabolic pathway enzymes or global transcription factors producing high yield lines with higher rates of photosynthetic carbon fixation. Analysis of these high yielding plants has allowed identification of novel genome editing targets.

We have deployed genome editing technology based on our C3008a trait in Camelina as well as our triple edited-line based on our C3008a, C3008b and C3009 traits in Camelina, which were deemed non-regulated by USDA-APHIS in 2017 and 2018, respectively. Plants that are not regulated by USDA-APHIS may still be subject to regulation by the FDA or the EPA depending on certain characteristics and the plant’s intended uses. We expect to increase our level of effort in this area in other crops, particularly canola, over the course of 2019 and are implementing a plan to deploy our genome edited traits into soybean, rice and corn. We have successfully edited the C4004 gene in rice and are currently developing performance data on the edited rice lines. We believe our genome editing targets as well as the improved crops we could develop using this approach may enable us to form collaborations or enter into license arrangements with a broader set of potential commercial partners in order to bring these genome edited traits forward into development in the near-term.

We plan to use any revenues we generate from license agreements around our genome editing targets to support our ongoing research and development efforts to enable step-changes in crop yield.

We developed the Camelina Fast Field Test model system to characterize, evaluate and de-risk novel yield trait genes.

One of the challenges the agricultural industry has faced over the years is translating early crop science discovery into value generating traits. In part this is because results from greenhouse studies in model plants have not translated well into field results in major crops. This is also in part because the plants used for discovery research have not been suitable for studies in the field and are not representative of the advanced seed or crop varieties (germplasm) used in commercial production, which have been subject to decades of intensive breeding to improve yield. Translating success when introducing non-plant genes into major crops has been very successful and the current biotechnology seed sector, which accounted for 457 million acres of crops worldwide in 2016, is based on using microbial genes in plants. The long timelines to progress early discoveries successfully into major crops and generate field data adds to the challenge.

For these reasons, Yield10 has put in place a process we call “Fast Field Testing” based on our Camelina oilseed platform. We believe that over time this will become a valuable tool in the trait discovery to translation effort. Camelina is an industrial oilseed well-suited to field trials, and we believe it is a good model for identifying promising new yield traits for canola and soybean. It is also very fast to modify and develop genetically stable seed for field planting. Ideally, we hope to be able to progress from trait identification to field planting in about 12 months. Our process is to identify trait genes of interest in Camelina and immediately begin putting them into canola and soybean, where the timelines to transform plants and generate field data are much longer. We can then progress the Fast Field Testing in Camelina and generate field data and a complete molecular analysis of plant material from the field. These results and data can then be used to inform how we progress the previously transformed canola and soybean.

We believe that this will provide the opportunity for go-no-go decisions in some cases and in other cases allow us to update our approach based on the results of our Fast Field Testing in Camelina. For example, with the longer development timelines needed to get canola and soybean ready for field testing, we expect to initiate additional modifications earlier in these crops, having identified the potential to further improve the outcome based on the results of our Fast Field Testing in Camelina.

In our 2017 and 2018 field test programs, we tested both first and second generation versions of C3003 in Camelina and in canola, an important North American oilseed crop. Overall, our findings in canola for first generation and second generation C3003 mirror closely our observations of the effect of the trait in Camelina, underscoring the value of Camelina as a predictive system for understanding the performance of our novel yield traits in development.

We are using our Camelina Field Test model system to de-risk and accelerate the demonstration of the trait gene value in major crops. As a particular trait is de-risked there is the potential for inflection points in value. If we can establish a strong correlation between the results from the Camelina system with future field data first from canola and then with soybean, then we may be able to leverage this to enter partnership and licensing discussions earlier while preserving the opportunity to capture a meaningful share of the upside value.

Through our investment in the Camelina platform Yield10 established the foundation for potential niche crop product opportunities such as nutritional oils and PHA biomaterials.

Our Oilseed Operation based in Canada provides us with unique capabilities in the development of oilseed crops.

We established our oilseeds subsidiary in Canada in 2010 to produce robust oilseed germplasm with engineered value-added traits for commercial crop production in western North America. Our oilseeds team is based in Saskatoon, Saskatchewan, with laboratories in the National Research Council (NRC) - Saskatoon facility and commercial greenhouse and laboratory facilities at nearby Innovation Place. Our team has developed and implemented technology to improve and accelerate engineering and trait evaluation of Camelina and canola. The team also plays a key role in designing and conducting greenhouse and field tests required to effectively evaluate novel yield traits.

We are establishing a network of commercial and science advisors to provide us with insight and opportunities to advance our industry alliances, crop research and development, and key intellectual property.

Yield10 named Sherri Brown, Ph.D., a former Monsanto Company executive, as a special commercial and technical advisor to the Company in 2018. Dr. Brown, who is currently a Managing Director at The Yield Lab, served from 1999-2017 in leadership positions at Monsanto, most involving the development and commercialization of new traits for corn and oilseed crops including soybean and canola.

Yield10 has pursued academic collaborations that have led to the discovery of novel yield trait genes. Researcher Danny Schnell, Ph.D. discovered the C3003 trait in an ARPA-e (a division of the U.S. Department of Energy ("DOE")) funded collaborative project at the University of Massachusetts in which Yield10 was a partner. In 2015, Prof. Schnell moved to Michigan State University where he is Chairperson, Department of Plant Biology and remains a collaborator on C3003. In 2018, Yield10 announced signing a global license agreement with the University of Missouri for advanced technology to boost oil content in oilseed crops, including C3007 and C3010, which are based on the discovery of a key regulatory mechanism controlling oil production in oilseed crops which can be used to increase oil content. Jay J. Thelen, Ph.D., Professor of Biochemistry at the University of Missouri, who discovered this mechanism, joined Dr. Schnell and Dr. Sederoff as a member of our Scientific Advisory Board in 2018.

We plan to seek U.S. and Canadian government grants to support our research and development goals.

Yield10 has been awarded grants over the last several years supporting research on strategies to improve the efficiency of photosynthesis, increase seed oil content, identify novel yield traits and test these novel traits in Camelina. This work is valuable because traits developed in Camelina have the potential to be developed and deployed in other oilseed crops. For example, in 2017, we were selected as a sub-awardee on a new DOE grant led by Michigan State University that commenced during the first quarter of 2018 to conduct research aimed at boosting oilseed yield in Camelina. We plan to continue to pursue government grants to defray research costs associated with our research and development activities.

We are operating with a lean organizational footprint which is evaluating our novel yield traits in greenhouse and field tests while maintaining efficient use of cash resources.

As of September 30, 2019, we had 25 full-time employees, with the majority directly involved with our research and development activities. We believe that our organizational capabilities are aligned with our research priorities and are complemented by our use of third-party infrastructure and certain service providers. With this approach we can leverage third-party infrastructure and capability without having to spend the time and capital needed to recreate them in-house. This is allowing us to focus our limited resources on deploying our core strengths against our key development goals. We expect to grow our research and development operations over time commensurate with building value in our business and advancing our traits through development while at the same time tightly managing overhead costs.

Our “GRAIN” Technology Platform

In the last decade there has been a dramatic expansion of new genetic engineering and systems biology tools: genomics data, metabolic engineering, high-throughput analytical tools, including whole organism gene expression analysis and metabolomics, and powerful genome editing technologies. At Yield10 we plan to build value by leveraging genome editing targets for revenue generation in the near-term while we independently work to demonstrate the economic value of our transformative genetic engineering-based yield breakthroughs in the longer term. The recent expiration of blocking patents on early inventions in the plant genetic engineering space means that we can now be more effective in research and development, leverage third-party service providers and independently drive key proof points in major

commercial crops such as canola, soybean and corn while focusing our resources on our core strengths. Yield10 is focused on increasing the inherent yield of major food and feed crops. Our goal is to “build better plants” which requires new approaches and innovation and, in our view, will most likely involve gene combinations and/or multi-gene systems.

At a fundamental level, increasing crop yield is a complex two-step carbon optimization problem. Harvested seed is mostly carbon fixed from carbon dioxide in the air by photosynthesis with oxygen coming from water in the soil and smaller amounts of nitrogen and phosphate both of which are applied as fertilizer. To achieve increased yield, the rate at which crops can fix carbon has to be increased. Based on our experience optimizing carbon flow in living systems, we know that increasing seed yield will likely require multiple trait genes to increase carbon fixation by photosynthesis at the front-end and direct the increased fixed carbon to the seed.

We have integrated advanced metabolic flux modeling capabilities with transcriptome network analysis to form the foundation of the GRAIN bioinformatics gene discovery platform. This discovery platform is the core of our Trait Factory. GRAIN takes a bottom up approach based on the flow of electrons and carbon through essential metabolic processes and a top down approach based on transcriptome network analysis. Plant growth at its core is a series of chemical reactions and these can be modeled to determine the best ways to optimize the yield of the targeted product. Advanced metabolic modeling based on flux-balance analysis and enzyme reaction thermodynamics and kinetics enables us to make predictions about which reaction modifications are most likely to achieve targeted performance improvements. However, as with all modeling approaches, the tool is only useful alongside the means and the data to test it in real plants. Here, Yield10 makes use of metabolic and transcriptome data generated from its high-photosynthesis, high-yield engineered plants as well as from academic publications and other public data to project optimal gene targets for modifications. By integrating the transcriptome network capabilities of our technology platform, we expect to be able to identify transcription factor genes whose activity profiles can be altered to optimize multiple steps in metabolic pathways or the flow of carbon in plant tissues of interest. In a crop like modern hybrid corn, which already produces vastly more seed than it needs to reproduce, our initial objective is to reduce or even eliminate the activity of the transcription factors that restrict further seed production.

We are excited about the prospects of C3003 in reducing the well-known yield losses that occur through photorespiration in C3 crops. C3 photosynthesis, the simplest type of plant photosynthetic system, exists in most agricultural crops used for human consumption, including canola, soybean, rice wheat and potato. We know C3003 has increased the rate of photosynthetic carbon fixation in our Camelina plants and we have been able to study these plants at the molecular level. Consistent with our initial hypothesis that downstream bottlenecks can be identified, we have found that in high yielding plants expressing C3003, the expression of other genes, including our C3004 trait gene is changed. We have carried out experiments to increase the activity of the C3004 trait gene in Camelina and have shown in growth chamber studies that this results in increased plant vigor, branching and up to a 65% increase in seed yield. We believe the C3004 gene, which may be engineered into crops using genome editing, has the potential to be used alone or be combined with the C3003 trait gene to further increase yield beyond what can be achieved with C3003 alone. We have work ongoing to evaluate the Camelina C3004 gene in canola, soybean and corn.

In crops having the evolutionarily advanced, more efficient C4 photosynthetic system, including corn, sugarcane and sorghum, the yield is already several-fold higher than in C3 crops. In this case, the hurdle to accomplish step-change increases in seed yield is higher as these crops are already more metabolically efficient. We validated our approach by verifying with experimental results the positive yield impact of three gene targets we identified computationally, which we believe to be an exceptional hit rate. These three yield genes, C4001, C4002 and C4003, significantly increased photosynthetic carbon capture and biomass production in switchgrass, an already high biomass yielding C4 crop. In this case our early experiments have been successful in demonstrating the potential to increase the rate of carbon fixation even in a high yielding C4 crop.

Plant scientists now have powerful genome editing tools, such as the CRISPR/Cas9 system, that enable single and multi-gene changes to be made in major crops; the challenge is knowing what combinations of genes to edit. We believe Yield10 is in a unique position to expand our learning and discover additional gene targets, or genes that need to be modulated, to optimize the flow of carbon to seed in these plants, and we have made considerable progress on this front.

Molecular analysis of high yielding plants expressing the global transcription factors has allowed the identification of 71 downstream transcription factors that are differentially expressed in the high yielding lines and are themselves targets for genetic manipulation. The expression of some of these genes is down regulated in the high yielding plants making them potentially promising targets for genome editing through well-known approaches such as CRISPR. We began by validating the predictive impact of three of these trait gene targets in switchgrass and confirmed their function and recently completed the genome editing of the first of these, C4004 in rice. We know the industry has

struggled to deploy transcription factors using traditional biotech approaches to improve crops particularly in hybrid corn. However, we are optimistic that we will be more successful introducing our global regulator genes using genome editing and believe that simple gene deletions to eliminate their function, will be significantly easier to implement and translate across crop varieties.

We are building significant capabilities and intellectual property around key oil biosynthesis pathways in plants based on technologies for increasing oil content in plants. In this area, we have focused on Acetyl-CoA Carboxylase (ACCase) as a key metabolic control point for oil production in plants and have assembled a portfolio of gene targets accessible through genome editing. ACCase gives rise to metabolic pre-cursors common to PHA biomaterials and edible oils, as well as cannabinoid oils found in industrial hemp and other plants. Given the central role of ACCase, we have been establishing a strong intellectual property position around controlling the flow of carbon at this key branch point and are advancing a number of gene targets including C3007, C3010 and C3012.

We believe our integrated GRAIN platform can be used to successfully identify new targets for improving crop yield and are working to leverage the platform in the near-term to secure research and development funding from industry partners.

Fast Field Testing System in Camelina

One of the challenges the agricultural industry has faced over the years is translating early crop science discoveries into value generating traits. This is in part because most of the plants used for discovery research have not been suitable for studies in the field. In addition, the plant systems used for discovery are not representative of the advanced seed or germplasm used in commercial production which have been subject to decades of intensive breeding to improve yield. The long timelines to progress early discoveries successfully into major crops and generate field data adds to the challenge.

In 2010, we established a research and development operation in Saskatoon, Canada staffed with leading oilseed researchers. Our team established a model for testing novel trait genes called the “Fast Field Testing” system based on our Camelina oilseed platform. We believe that this system has become a valuable tool for our yield trait discovery and translation effort. Camelina is an industrial oilseed with reasonable field performance providing a robust model for canola and soybean and it is well suited to multi-site field tests and larger scale trials. Camelina is a plant that can be readily genetically modified and bred through the efforts of our skilled staff to deliver genetically stable seed sufficient for planting in field tests. We have shown that we can go from the identification of a potential yield trait gene or combinations of genes to field planting in about 12 months. In our Fast Field Tests, we typically collect and analyze a broad set of data on our transgenic or genome edited plants including parameters such as stand establishment, flowering, maturity, seed weight, seed size, oil content and oil composition. We also perform molecular analysis on plants of interest. We are using our Camelina Fast Field Test system to identify and screen trait genes of interest while deploying them in parallel into crops of commercial interest including canola, soybean, rice, corn and wheat where the timelines to obtain stable plant lines and field data are longer.

Traits in Development

Yield10 Bioscience has ownership or licensed rights to several crop trait genes and our lead yield trait gene C3003 is currently well-positioned in terms of translation and demonstration in key crops. Yield10 has exclusive rights through ownership or licensing of patent applications, or is preparing patent applications, covering the trait genes listed in the accompanying table.

We identified the C3000 series of novel yield traits based on establishing new metabolic pathways in crops. We have tested our lead yield trait gene C3003 in Camelina in both greenhouse and field tests and have previously reported results from these studies. We are moving this promising trait forward in additional crops including canola, soybean, corn, sorghum and rice. Our other C3000 series traits may be accessible through genome editing and are being tested in various target crops as well.

We have also identified the C4000 series of novel yield traits and gene editing targets addressing increases in seed yield and biomass. We have shown that our C4000 series traits, which comprise global regulatory genes discovered through our GRAIN technology platform, may have the potential to significantly enhance photosynthesis and carbon capture in key crops. We are moving members of the C4000 series of traits forward in several crops including wheat, rice, corn and forage sorghum using mainly third party resources and capabilities while retaining control of intellectual property.

Novel Yield Trait Gene C3003

C3003 represents the lead novel yield trait gene in our trait pipeline. C3003 is a scientific discovery made in one of our academic collaborations funded by ARPA-e, a division of the DOE. Our academic collaborator is continuing work to characterize C3003 and some of this work is funded by a DOE grant under which Yield10 is a sub-awardee conducting research supported by the grant.

C3003 appears to be a unique gene that impacts photorespiration, a biochemical pathway in C3 plants that is responsible for significant losses in yield. Yield10 is progressing the introduction of the C3003 trait gene as well as improvements to the C3003 trait in Camelina, canola, soybean, corn and rice. In 2019, we are conducting additional greenhouse and field test activities to continue generating yield and agronomic data on C3003 in a variety of important crops.

Camelina

We have extensively utilized our Camelina Fast Field Testing Platform to evaluate the mechanism and effect of C3003 in crops. Over the past three growing seasons, 2016-2018, we have produced field-grown seed and field tested numerous stable Camelina seed lines containing first generation C3003, second generation C3003 and certain prototypes of traits related to C3003. Through this work, we have collected important molecular, agronomic and seed yield data that has enabled us to characterize these traits as well as understand important differences in the effects they produce in field-grown plants.

Our greenhouse and field work with C3003 in Camelina have allowed us to capture data on the performance of the trait. The results from our field tests show that first generation C3003 produces significant improvements in seed yield although the individual seed weight in these lines is decreased as compared to controls, likely due to a change in carbon partitioning in the plant. Field test results for second generation C3003 (seed specific expression of the trait), show improvements in seed yield, harvest index and overall agronomic performance, while also maintaining typical seed size as compared to control plants. There were no significant changes to oil content or oil composition with either version of the trait as compared to control plants. In our 2019 field tests, we saw some indications of drought resistance with C3003, an observation we plan to follow up on in subsequent field tests of this trait.

Underscoring the value of our Camelina Platform in the evaluation of C3003, our observations around the increases in seed yield along with differences in seed weight have been observed in some of our recent studies with canola and soybean lines. Based on encouraging data obtained in Camelina with first and second generation C3003, we are continuing to progress the evaluation of the C3003 yield trait gene in parallel in various commercial crops including canola, soybean, corn and rice, where we believe step-change increases in seed yield could improve the prospects for global food security and create considerable economic value.

Canola

Canola is an important North American oilseed crop harvested for its oil. We are targeting step-changes of 10-20% in the evaluation and development of novel traits to increase seed yield in canola. In our field tests of canola in 2018, we achieved seed yield improvements in some events at the low end of this range (11%), and based on these results, we will progress C3003 into the preliminary commercial development phase in canola in 2019. The key activities to be completed during this phase include development of commercial quality events in elite canola germplasm, execution of multi-site, multi-year field studies and development of regulatory data as appropriate.

In 2019, we are conducting additional field tests in Canada with second generation C3003 in canola. Harvest of the test fields is expected in 2019, which will enable the collection and evaluation of agronomic, seed yield, oil content and other data from the studies.

We evaluated our second generation C3003 yield trait in canola for the first time in canola in 2018. In these field tests, we monitored key agronomic and growth parameters of the plants throughout the field test and collected yield data including total weight of harvested seed, individual seed weight and oil content in our transformed plants as compared to control plants. The best second generation C3003 canola lines showed an increase in seed yield of 11 percent as compared to control plants, a statistically significant outcome. In second generation C3003 canola plants, the weight of an individual seed (measured using 1,000 seeds) was similar to control plants, an expected outcome using the second generation version of the C3003 trait.

The results we obtained in canola were similar to results obtained in prior studies with Camelina, illustrating that our Fast Field Testing system in Camelina is a valuable tool for effectively screening novel yield trait genes and

dynamically adapting our approach to trait development as we work to translate these improvements into commercially important crops.

Soybean

Yield10 has limited capabilities related to engineering soybean. However, because soybean is the leading North American oilseed crop, we initiated deployment of both first and second generation C3003 into soybean in 2016 through an academic collaborator. We recognize that the scale of this program is limited and that it will serve mainly to generate research data. Yield10 is currently exploring additional third-party options for conducting soybean transformations to increase the scope of our internal program. In 2017 we generated early greenhouse data and in 2018 we grew C3003 soybean plants at sites in Canada to produce field-grown seed. We expect that additional development work including the generation of more C3003 lines will continue in soybean with our academic collaborator in 2019.

Preliminary observations based on a small number of events from our greenhouse studies suggest that results for C3003 obtained in Camelina and canola are translating into soybean. First generation C3003 produced seeds with lower individual seed weight while typical individual seed weight was observed with second generation C3003 in soybean. Further, our greenhouse results show that there is an increase in branching in the plants for some of the events tested. This is significant because more branching provides more sites on the soybean plant for seed pods to develop which can be associated with obtaining higher yielding plants.

In December 2017, we granted a non-exclusive research license to Bayer to evaluate our novel C3003 and C3004 yield traits in soybean. Under the license, Bayer is working with C3003 in its soybean program as a strategy to improve seed yield. We anticipate that Bayer will generate field test data with C3003 pursuant to the research license. The Bayer license was expanded to include a new discovery relating to C3004 that will enable them to begin work deploying and testing the trait in their soybean program.

Corn

Corn is the highest value commercial row crop grown in the United States. We initiated an early development program in corn in late 2018 with the objective of evaluating novel seed yield and drought tolerance traits in this crop. Under this program, novel traits discovered by Yield10 are being deployed in corn by a third-party agriculture company with proven expertise introducing new traits into corn. The yield traits included in the corn development program are C3003, C3004, and C3011, as well as the transcription factors C4001, C4002, and C4003. This aspect of the development activity is expected to be completed in early 2020. We plan to engage an additional third party to conduct field testing of the novel traits in corn to evaluate the impact on seed yield.

Novel Yield Trait Gene C3004

While the role of C3004 is currently not well understood and we continue to investigate the role of the gene in plant metabolism, we believe that it may have an effect on carbon partitioning in plants. We also believe that, under certain conditions, this effect may potentially be additive with the activity of C3003. Our ongoing research will continue to investigate the activity of C3004 alone and in combination with C3003 to produce increases in seed yield in crops.

We began our investigation of C3004 in Camelina. We constructed C3004 to increase expression of the gene in Camelina. Stable plant lines were developed and we performed yield studies in a controlled environment growth chamber. In these studies, increased expression of C3004 in Camelina results in a significant increase in plant growth and vigor, increased seed yield, and in some cases increased individual seed weight. In these limited studies, six Camelina plant lines containing C3004, average seed yield (grams/plant) increased by 26 to 65 percent over control plants. We also measured tertiary branching in a subset of plants and found that the increase in seed yield seen in the plants was also accompanied by an increase in tertiary branching. While early stage and based on a small sample of events, the data suggest that C3004 may hold significant promise as a novel yield trait.

In 2019 we are conducting greenhouse and field tests in Camelina to continue to generate additional seed yield and agronomic data on C3004. We also plan to test C3004 in combination with C3003 in Camelina to investigate whether the traits could be additive or synergistic. We have also fast-tracked the deployment of C3004 into canola and corn where we will engineer lines and begin testing to determine if this trait produces improvements in seed yield in other crops. The version of the C3004 trait we tested in our Camelina studies was genetically engineered using recombinant DNA; however, we believe that it may be possible to develop versions of the trait that are genome edited, potentially enabling a path to non-regulated status for C3004 plants under current USDA-APHIS rules.

Oil Enhancing Traits

With increasing focus on health and wellness, food safety and sustainability in developed countries, we anticipate a rise in demand for new varieties of food and food ingredients with improved nutritional properties. This concept is currently being implemented in agricultural biotechnology, in both canola and soybean that have been modified to alter the composition of the oil produced. High oleic canola and soybean oils are being marketed as "healthier" than other oils; we believe the ability to make similar marketing claims directly to the consumer will be a feature of newly developed products in this space. We expect consumer demand for identity preserved specialty ingredients will rise, and we believe that Yield10's crop yield technologies and crop gene editing targets could be useful in this emerging field.

Based on our study of metabolic pathways in oilseed crops, we believe there is an opportunity to apply genome editing to significantly increase oil content in oilseed crops including canola, soybean, sunflower and safflower. In cases where the edible oil is the primary economic value driver for the crop or in cases such as high oleic soybean where the crop has been modified to improve the fatty acid profile, increasing oil content is a valuable trait. This potential also extends to Camelina where recent clinical studies have shown that Camelina sativa oil, but not fatty fish or lean fish, improved serum lipid profile in subjects with impaired glucose metabolism. This randomized, controlled study was recently published in the journal Molecular Nutrition and Food Research, U. Schwab, et. al. (2018). Improving the oil content and yield of Camelina seed could make this an attractive crop for producing nutritional oils. In 2017 and 2018, we received confirmation from USDA-APHIS’s Biotechnology Regulatory Services (BRS) that two types of our genome-edited Camelina plant lines developed using CRISPR/Cas-9 genome editing technology for increased oil content were not considered to be regulated under 7 CFR part 340, clearing the way for field testing in the U.S. The first type is based on the inactivation of an enzyme expected to increase seed oil content in Camelina, a trait we have designated as C3008a. The other type is based on the inactivation of three enzymes to enhance the production of oil and is designated as our triple edit, or C3008a, C3008b and C3009 trait containing line. We are currently evaluating combinations of the genome editing targets to optimize oil content in Camelina and canola, and plan to do so in soybean with the objective of obtaining plant lines that are not considered to be regulated by USDA-APHIS under the current regulatory framework of 7 CFR part 340.

In 2018 we signed an exclusive global license agreement with the University of Missouri for advanced oilseed technology including C3007 and C3010, which are promising targets involved in oil biosynthesis. We are working to deploy C3007 in oilseed crops with the objective of increasing oil content through methods that could result in a plant line that is not considered regulated by USDA-APHIS under 7 CFR part 340. We have produced a genome edited version of C3007 in canola and further development and evaluation of the trait is underway. In 2019 we signed an additional exclusive global license with University of Missouri for additional oilseed technology we named C3012.

C4000 Series Traits

We have used our GRAIN platform to study global transcription factors and identify novel yield traits in the C4000 series. These traits may be powerful regulators of plant growth and represent a potentially valuable resource for identifying genome editing traits for crops. We have recently shown that traits from the C4000 series can significantly increase photosynthetic efficiency as well as aboveground and below ground biomass production in our switchgrass plants.

In 2018 in the journal Plant Science, we reported that our novel C4001 and C4003 traits have been shown to significantly increase plant biomass yield in switchgrass. Switchgrass plants expressing C4001 resulted in a total increase in biomass of 75-100 percent in leaves and stems as compared to controls. Expression of C4003 in switchgrass resulted in a total increase in biomass of 100-160 percent in leaves and stems as compared to control plants. Increasing biomass yield is important for forage crops such as sorghum, silage corn, and alfalfa.

We are testing certain of our C4000 series of traits to increase seed yield in wheat, rice, and corn, as well as to increase biomass in forage sorghum. Using internal resources, we have been able to progress the C4001 trait gene in rice. In a collaboration with the National Research Council of Canada we have introduced the C4001 and C4003 traits into wheat and expect to generate performance data from wheat lines in the coming year. With rice and wheat, we do not plan to evaluate traditional biotechnology traits in the field or develop them as products but to use them as a source of new genome editing trait leads. We have completed the editing of the first of the C4004 trait in rice and are currently growing these plants in the greenhouse. Forage Genetics began work with certain of our C4000 series traits through a research license signed in 2018 to assess the potential of our traits to increase biomass in forage sorghum. We also began early development work in late 2018 to assess certain C3000 and C4000 series traits in corn through a third-party agricultural company. We expect the first phase of this work to be completed by early 2020.

We expect evaluation of C4000 series traits in these target crops will continue to advance in 2019. Traits in this series and the proof points we expect to generate may provide us with an opportunity to selectively partner with others for the development of these traits in major commercial food, feed, and forage crops.

PHA Trait

While maintaining our focus on the development of novel yield traits for key crops based on a licensing model, as part of our business development activities we have been working to develop independent business opportunities for Yield10 in the specialty oils and niche crop product space. The target of this effort is sustainable business solutions to support global food production and other specialty applications. Yield10 is a pioneer in the development of technology for producing PHA/PHB biomaterials in crops. Seed-based PHA/PHB production provides an opportunity to sustainably produce these natural biodegradable materials at low cost, disrupting the cost advantage of the petroleum plastics they can functionally replace. Based on our engineering projections, we believe the costs achievable in Camelina will also enable broad use of this material for water treatment applications where it acts as a maintenance-free growth substrate for bacteria that convert nitrate to nitrogen gas thereby reducing pollution and algal growth. Scientific data has clearly shown that fertilizer (NPK) is essential for global food security, however its use is also a major source of nutrient pollution in our waterways. We need to develop sustainable economically attractive ways to reduce fertilizer run-off and simple cost-effective ways to remove it from water where it comes from multiple sources including natural processes and septic systems. This market application has been known since the 1980’s but has been constrained by the high costs of fermentation-based production technologies. We believe the potential exists to use our Camelina platform as a sustainable low-cost source of PHA biomaterials to improve the overall sustainability of food production and to reduce nutrient pollution of our waterways.

A recent patent application was filed by Yield10 describing a discovery around maintaining the viability and vigor of Camelina seed containing high levels of PHA polymer. This is an important step toward the development and commercialization of a seed-based production platform for PHB using Camelina. Yield10 is in the early stages of developing a commercial business model focused on PHA produced in Camelina for water treatment applications.

We believe by developing the PHA Camelina platform as a cash cover crop we can create new sources of revenue for farmers, independent of export markets, reduce run-off from fertilizers and produce a natural biodegradable product that can be used to mitigate the impact of fertilizer run-off when it occurs as well as reduce nitrate pollution from aquaculture and septic systems. By focusing on North America we believe we can avoid the high costs and time delays associated with global deregulation of a biotech crop and potentially benefit from the ongoing modernization of the USDA-APHIS regulatory process.

PHA biomaterials are widely useful for functionally replacing petroleum-based plastics in a wide range of packaging applications. The plastics industry, which produces more than 350 million tons of material per year globally, is facing intensive scrutiny due to the failures in plastics recycling and increasing plastic waste in the environment. As natural biomaterials, PHAs fully degrade over time in the environment yet have excellent shelf life in use. We estimate that PHA biomaterials can be produced at very low cost in oilseeds based on our newly patented technology. When we made the transition to the Yield10 business we divested our PHA bioplastics (biomaterials) assets based on the microbial fermentation platform but retained the patents and field of PHA production in engineered crops. Our current approach to this market is to execute agreements with petroleum, chemical or plastics companies to commercialize this opportunity. These companies are also potential sources of funding to support the development of the PHA Camelina crop.

Target Crops

Our research and early development work in our C3000 and C4000 series traits suggests that our technology may be applicable to a wide range of crops harvested for food and animal feed uses. We believe that if novel yield traits could be successfully developed and commercialized in any of these crops, farmers would be able to improve the productivity of their land to meet rising demand for food and feed, thereby creating significant economic value.

In considering our strategy to develop our technologies we segregate our trait genes into two classes: trait genes based on using non-plant genes to add new functionality to crops which are by definition GM due to the insertion of foreign recombinant DNA; and trait genes that we may be able to deploy in lines that are not considered regulated by USDA-APHIS, which encompass our trait genes that are based exclusively on plant genes. We see the opportunity to deploy our trait technology in a broader set of food and feed crops many of which are not currently GM. We plan to pursue our GM trait genes in crops which are currently GM and where the economics can sustain the cost and timelines for deregulation. We are aware of the current USDA-APHIS GM crop regulation review and the reality that GM likely

will remain an issue for some NGO groups regardless of the science. For our GM yield trait genes, we are targeting seed yield increases on the order of 10 to 20 percent over the current elite seed lines, increases which reflect the order of magnitude step-changes necessary to address global food security.

The crops we are targeting for development are described below.

Camelina or Camelina sativa is an oilseed crop in limited cultivation in North America and Europe. Camelina has received recent attention as an industrial oilseed for the production of biofuels, novel industrial lipids, and oleochemicals. In addition, its meal has been identified for development as an animal feed supplement and its oil as a fish feed supplement. Recent clinical studies have shown that Camelina sativa oil, but not fatty fish or lean fish improved serum lipid profile in subjects with impaired glucose metabolism-a randomized controlled study published in the journal Molecular Nutrition and Food Research, U. Schwab, et. al. (2018). Improving the oil content and yield of Camelina seed could make this an attractive crop for producing nutritional oils. While it is not currently a commercially significant crop, research suggests that efforts to improve seed yield, oil content and fatty acid composition, and tolerance to heat stress may expand the commercial adoption and cultivation of Camelina. We believe that the production of PHA biomaterials in Camelina could provide economic returns for farmers to justify large acreage adoption and enable the low-cost production of this product for new markets including water treatment and plastics replacement applications. We believe crop-based production will enable an advantageous cost structure thereby eliminating one of the significant remaining barriers to entry for broad adoption of these materials.

Canola or Brassica napus is a cultivar of rapeseed which produces a higher value edible oil favored by consumers because it has a healthier fatty acid profile than corn or soybean oil. The canola crop was developed in Canada where it is primarily grown today with additional acreage grown in the U.S. Currently the vast majority of the canola grown in North America contains two seed enhancement technologies, herbicide tolerance and hybrid seed. Both Roundup Ready (Monsanto, now Bayer) and Liberty-Link (Bayer) varieties of canola are grown and were introduced to the market in 1990s. Approximately 24.7 million acres were planted in Canada and the U.S. in the 2018 growing season. The Canola Council of Canada has set yield goals of 52 bushels/acre for 26 million metric tons of production to meet global market demand for canola by 2025. Yield10 is targeting a 10-20 percent or greater increase in canola seed yield. With a 2017 harvest of 939 million bushels of canola (Statistics Canada) and assuming an average farm gate price of $10.00 per bushel, a 20 percent yield increase in canola represents a total potential added annual value of $1.9 billion that could be shared among the companies in the canola value chain.

Soybean or Glycine max is an oilseed crop used for food, food ingredients, food additives and animal feed. The soybean can be harvested for oil used in food and industrial applications, and soybean meal is a significant source of protein for use mostly in animal feed but also for direct human consumption. Fermented soy foods include soy sauce and tempeh, and non-fermented food uses include soy milk and tofu. Soybeans are widely cultivated in North and South America, where a majority of the seed planted is genetically modified. An estimated 94.4 million acres of soybean will be planted in the U.S. and Canada in the 2018/2019 growing season. According to the USDA, the U.S., Brazil and Argentina together represent approximately 80 percent of global soybean production. Yield10 is targeting a 20 percent or greater increase in soybean seed yield. Assuming a 2018/2019 U.S. harvest of 4.5 billion bushels (USDA) and an average farm gate price of $10.00 per bushel, a 20 percent yield increase in soybean represents a total potential added annual value of $8.8 billion that could be shared among the companies in the soybean value chain.

Corn is a crop grown globally and used for animal feed and for producing starch which can be used as a raw material for producing food ingredients and food additives, as well as for use in the production of paper, packaging materials and other items. GM maize was grown for the first time in the U.S. and Canada in 1997. Currently, about 80 percent of maize/corn production in the U.S. is genetically modified. It was estimated that more than 83 million acres of corn were planted in North America in the 2018 growing season. The traits commonly used in today’s corn cultivars provide insect resistance and herbicide tolerance. In many GM seeds sold today, these traits are stacked (“stacked” refers to the practice of adding multiple traits to an elite plant line). Europe has limited production of GM corn, where Spain is a leading producer. In this case, the most widely used GM trait (Bt) protects against the corn borer insect. Special protocols must be followed in Europe to avoid mixing of GM corn with conventional corn. Corn has the more efficient C4 photosynthesis system and Yield10 is targeting a 10 percent yield increase in corn. With a projected 2018/2019 U.S. harvest of 14.4 billion bushels and an average per bushel price of $3.50, a 10 percent yield increase in corn represents a total potential added annual value of $5.1 billion that could be shared among the companies in the corn value chain.

Rice is the staple food for over 50 percent of the global population. World crop production of rice for 2018/2019 is estimated at approximately 495 million metric tons. Rice is grown in tropical and subtropical regions around the world. Rice cultivation takes place primarily in China, India and Southeast Asia. Typically, improvements to rice yield have been achieved through traditional plant breeding approaches. Genetic engineering approaches are being investigated to

develop rice hybrids and to protect rice from weeds and insect pests. Additional biotechnology approaches are being taken to improve the nutritional value of rice. While Yield10 has not established a target for yield improvement in rice, early work is underway to evaluate the potential of our technologies in this globally important food crop.

Wheat is a species of grass cultivated broadly worldwide as a staple cereal crop. Wheat requires processing to be used as food, mainly in the form of flour for bread, baked goods and pasta. Wheat may also be used as an industrial starch, as a food additive or as a production component in the textile and paper industries. Improvements to wheat yield have typically been achieved through plant breeding approaches. Wheat production ranks third among U.S. field crops in planted acreage, production and gross farm receipts behind corn and soybeans. The planted area for wheat (winter and spring varieties) in the U.S. and Canada combined for 2018 was estimated at 72 million acres.

Forage crops are grown expressly for biomass used for feeding livestock. Typical forage crops include both annual and perennial crops such as various grasses, silage corn, alfalfa and sorghum. Biotechnology traits have been previously introduced into silage corn and alfalfa. Other forage crops could be amenable to gene editing strategies to increase biomass yield per acre. We believe that our technology and traits that increase biomass may have application to forage crops.

Regulatory Requirements

Since the first successful commercialization of a biotechnology-derived agricultural crop in the 1990s, many new crop varieties have been developed and made available to farmers in the U.S. and worldwide. U.S. farmers have rapidly adopted many of these new biotechnology-derived varieties, so that in 2016, 92 percent of the corn, 93 percent of the cotton and 94 percent of the soybeans planted in the U.S. were varieties produced through traditional forms of genetic engineering. A significant percentage of the production of other crops planted and harvested in the U.S., such as alfalfa, papaya and sugar beet, are also biotechnology-derived.

Biotechnology-derived or genetically engineered crops are subject to a significant amount of regulation in the U.S. and around the world. Field tests and field trials of such crops need to ensure that traits in development do not escape or mix with native plants, and crops that may be used as human food or animal feed must meet certain safety standards, but government regulations, regulatory systems and the politics that influence them vary significantly among jurisdictions.

For purposes of this discussion, the term “GE” includes both biotechnology-derived or genetically engineered plants that are modified by the insertion of recombinant DNA (“Traditional Genome Modification”) and biotechnology-derived or genetically engineered plants that are modified through the application of more modern techniques of genome editing. We have seed traits that fall within each of these two generalized categories of GE plants, as summarized above under the subheading “Traits in Development.”

United States Regulation

The U.S. Government agencies primarily responsible for overseeing the products of modern agricultural biotechnology are the U.S. Department of Agriculture (USDA), the U.S. Food and Drug Administration (FDA) and the U.S. Environmental Protection Agency (EPA). Depending on its characteristics, a product may be subject to the jurisdiction of one or more of these agencies under the federal government’s 1986 Coordinated Framework for the Regulation of Biotechnology, as updated. Regulatory officials from the three agencies regularly communicate and exchange information to ensure that any safety or regulatory issues that may arise are appropriately resolved within the scope of authority afforded to each agency under their respective statutes. Other environmental laws or regulations also may be implicated, depending on the specific product and its potential applications or intended uses. EPA’s principal oversight role is for biotechnology-derived products that are intended for use as pesticides or herbicides, under the authorities granted to the agency under the Federal Insecticide, Fungicide, and Rodenticide Act and the Toxic Substances Control Act. Our business strategy for major grain crops is to develop yield and performance traits for licensing to the major seed companies. We have no current plans for the development of pesticide or herbicide GE traits that would be subject to the procedures and requirements of the EPA under these statutes.

Our seed traits and any future products that are successfully developed containing our seed traits, however, are or will be subject to USDA and FDA regulatory requirements. Those requirements will vary depending on the particular seed trait and the type and intended use of any product that will be commercialized. Future products which we plan to produce and sell for example for use in water treatment may potentially have EPA regulatory requirements and the regulations relating to manufacturing and consumer protection will need to be addressed.

First, within USDA, the Animal and Plant Health Inspection Service (APHIS) is responsible for protecting agricultural plants from pests, diseases and noxious weeds. Under the Plant Protection Act ("PPA"), USDA-APHIS has

regulatory oversight over products of modern biotechnology that could pose such a risk to domestic agriculture and native plants. Accordingly, USDA-APHIS regulates organisms and products that are known or are suspected to be plant pests or to pose a plant pest risk, including those that have been altered or produced through various genetic engineering techniques. These GE plants are called “regulated articles” in the relevant USDA-APHIS regulations, which are codified at 7 CFR part 340 (“Part 340”). The PPA and the implementing regulations in 7 CFR part 340 empower USDA-APHIS to regulate the import, handling, interstate movement and release into the environment of regulated articles, including certain GE organisms undergoing confined experimental use or field trials. Regulated articles are reviewed to ensure that, under the proposed conditions of use, they do not present a plant pest risk by ensuring appropriate handling, confinement and disposal.

Seed traits developed using Traditional Genome Modification, such as our C3003 yield trait that leverages the biological functions of an algal gene, are regulated under 7 CFR part 340. Regulated articles are subject to extensive USDA-APHIS oversight, including but not limited to permitting requirements for import, handling, interstate movement and release into the environment.

If, however, USDA-APHIS determines that a GE plant is unlikely to present a greater plant pest risk than its unmodified counterpart, the newly developed crop will no longer be subject to the permitting and other regulatory processes that are overseen by the agency (i.e., it will no longer be treated as a potential plant pest). Such a determination by the USDA-APHIS is called not regulated under the 7 CFR part 340 regulatory framework. The regulations establish detailed procedures for how a developer of a new GE plant may petition USDA-APHIS to determine if modified plant lines are not regulated under the 7 CFR part 340 framework, which is an official agency finding that the particular article is unlikely to pose a plant pest risk and therefore no longer needs to be regulated under 7 CFR part 340 and the PPA.

USDA-APHIS conducts a comprehensive science-based review of the petition to assess, among other things, plant pest risk, environmental considerations pursuant to the National Environmental Policy Act, and any potential impacts on endangered species. The duration of the petition process varies based on a number of factors, including the agency’s familiarity with similar GE products, the type and scope of the environmental review conducted, and the number and types of public comments received. If, upon the completion of the review, USDA-APHIS approves the petition and the product is no longer deemed a “regulated article,” the developer may commercialize the product, subject to any conditions set forth in the USDA-APHIS written decision issued in response to the petition for determination of non-regulated status.

As previously described, our seed traits developed using Traditional Genome Modification are regulated under 7 CFR part 340 and are subject to USDA-APHIS permitting requirements. In recent years, however, we and others have submitted various petitions to USDA-APHIS to determine whether particular GE plants developed through the use of different genome editing techniques meet the not regulated status under the 7 CFR part 340 framework administered by the agency. In general, lines developed using genome editing approaches have been deemed not to be regulated by USDA-APHIS under 7 CFR part 340. The USDA also announced in March 2018 that it would not require an assessment on products that used modern forms of mutagenesis if it was clear these outcomes could occur in nature. The USDA stated at that time that it did not “have any plans to regulate plants that could otherwise have been developed through traditional breeding techniques as long as they are developed without the use of a plant pest as the donor or vector and they are not themselves plant pests.” This USDA policy statement applies to genetic deletions of any size, which would include genome editing through CRISPR-Cas9 and other emerging technologies, although it remains to be seen how this policy announcement will be implemented by USDA-APHIS and what practical effect that may have on seed trait developers like us and our competitors.

Historically, changes to the U.S. regulatory paradigm for agricultural biotechnology have been infrequent, are typically preceded by notice, and are most often subject to public comment, but there can be no guarantee that the USDA-APHIS governing regulations and policies will not change.

We have submitted two petitions under 7 CFR part 340 for a determination of the regulatory status (also known as the “Am I Regulated?” letter) to USDA-APHIS’s Biotechnology Regulatory Services in order to confirm that the following two traits designed to increase oil content are not going to be regulated by the agency: (i) the single trait C3008 Camelina plant line, developed using CRISPR genome editing technology for increased oil content; and (ii) the triple-edited Camelina line that combines three gene traits, C3008a, C3008b and C3009, to increase oil production. In both cases, USDA-APHIS's Biotechnology Regulatory Services approved our petitions and confirmed that each of these novel plant lines would not be treated as a regulated article.

To our knowledge, our triple-edited Camelina line which was determined to not be regulated under 7 CFR part 340 in September 2018, is the first CRISPR-edited triple-trait plant determined by the agency to be not to be regulated.

Given our business strategy to develop certain multi-trait genome edited plant lines, this achievement should facilitate our ability to put more of our novel yield traits through the petitioning process and the agency’s scientifically driven decision-making process, with the expected end result of having lines containing more of our traits treated as not to be regulated under 7 CFR part 340 (as compared to our seed traits developed using Traditional Genome Modification, which are regulated articles). We expect to continue to make appropriate use of the “Am I Regulated” letter procedures to clarify the regulatory status of our new GE seed traits as they are developed.

Also, we tested the C3008 single-trait Camelina line in a 2018 field evaluation that took place in the United States following a notification in 2017 that the line would not be regulated under 7 CFR part 340.

Separate from the plant breeding and planting issues and USDA-APHIS regulation under 7 CFR part 340, a GE plant also will be regulated by the FDA if it is intended to be used as human food or animal feed. The FDA regulates the safety of food for humans and animals, and foods derived from GE plants must meet the same food safety requirements as foods derived from traditionally bred plants (also called conventional foods).

Since 1992, the FDA has had in place a voluntary consultation process for developers of bioengineered food (“Biotechnology Consultations”). Final agency decisions and other information from these Biotechnology Consultations are made publicly available by the FDA. Biotechnology Consultations are data-intensive and examine the new food product’s safety and nutritional profile, among other issues. Generally, the FDA has found that such food products do not pose unique health risks to humans or animals, but if a novel allergen or other distinction from the conventional food is present in the new plant variety, the agency may require specific label statements on the product to ensure that consumers are made aware of material differences between GE and conventional versions. The FDA primarily derives its regulatory power from the Federal Food, Drug, and Cosmetic Act, which has been amended over time by several subsequent laws. Among other oversight and inspection responsibilities, the FDA regulates ingredients, packaging, and labeling of foods, including nutrition and health claims and the nutrition facts panel. Foods are typically not subject to premarket review and approval requirements, with limited exceptions.

In October 2018, FDA leadership issued a document entitled the “Plant and Animal Biotechnology Innovation Action Plan” (“Action Plan”) that identified three key priorities for the agency in this area: 1) advancing human and animal health by promoting product innovation and applying modern, efficient and risk-based regulatory pathways; 2) strengthening public outreach and communication regarding the FDA’s approach to innovative plant and animal biotechnology; and 3) increasing engagement with domestic and international partners on biotechnology issues. The Action Plan also stated that the FDA has reviewed the comments and other information it received in response to the January 2017 request for comments, and that it intends to develop guidance for the industry explaining how the FDA’s existing regulatory policy for foods derived from new plant varieties applies to foods produced using genome editing. The forthcoming draft guidance is expected to be released for public comment in 2019. The FDA also stated in the Action Plan that it intends to begin updating the existing procedures for voluntary Biotechnology Consultations to reflect the agency’s 25 years of experience with foods derived from biotechnology plants and to incorporate any additional issues related to genome editing of food crops. Such procedural updates are expected to be developed and implemented over the next two years.

Canadian Regulation

In Canada, GE crops and the food products into which they are incorporated are regulated by multiple government agencies under a federal framework for the regulation of biotechnology products that is similar to the U.S. system. First, the CFIA is the lead agency for ensuring that a new agricultural biotechnology crop will not pose new risks to Canadian plants, animals and other agricultural commodities. The PBO is responsible for conducting environmental assessments of PNTs. Authority for the PBO includes both approving confined field trials with the PNT through permits and authorizing their “unconfined release” as a first step towards commercialization. PNTs are defined in the Canadian Seeds Regulations as (i) plants into which a trait or traits have been intentionally introduced, and (ii) where the trait is new in Canada and has the potential to impact the environment. The CFIA also has in place a remutation policy, whereby

plants containing the same mutation as a previously authorized plant of the same species are included in the authorization of the original PNT and are therefore subject to the same conditions.

Second, under the Food and Drugs Act and related regulations, Health Canada is responsible for reviewing a pre-market safety assessment that must be submitted by the manufacturer or importer of a “novel food,” a term of art that includes any PNT or other or biotechnology-derived foods. The safety assessment should provide assurances that the novel food is safe when prepared or consumed according to its intended use before it enters the Canadian market and food system. A multi-disciplinary team of experts from Health Canada will evaluate the data and information about the novel food and make a determination regarding whether it is safe and nutritious before it can be sold in Canada, as well as whether any restrictions are warranted under applicable law or the product’s safety profile. Health Canada’s final decision documents regarding the safety of these novel foods are made available to the public by the government. As in the United States, approval of a PNT or a novel food product does not take into account the method with which such product was produced. Rather, Health Canada employs a product-based (as opposed to a process-based) approach to its regulatory oversight of such emerging foods and food ingredients.

As the lead agency for public health and safety, Health Canada also works in conjunction with the CFIA on food labeling oversight when it has identified a potential health or safety issues with a food that could be mitigated through labeling or other disclosures. For example, if the biotechnology-derived food contains a new allergen that is otherwise not present in the conventional version of the food, then specific label statements will be required to alert consumers to that important health information. However, the CFIA has primary oversight over non-health issues related to food labeling, packaging, and advertising. Accordingly, the CFIA is the lead agency for ensuring that food labeling, and advertising meet the legal requirements of the Food and Drugs Act, and that labeling representations do not create a potential risk of fraud or consumer confusion and are compliant with Canada’s voluntary disclosure standard for GE food ingredients.

Environment Canada is also available to serve as a regulatory “safety net” if a novel product does not naturally fall within the jurisdiction of the CFIA, Health Canada, or the Pest Management Regulatory Agency that oversees pesticide products.

Our work involving the development, greenhouse testing and field testing of novel yield trait genes in crop plants requires certain government and municipal permits and we must ensure compliance with all applicable regulations including regulations relating to GE crops. With laboratories and greenhouses in both the U.S. and Canada, we are also subject to regulations governing the shipment of seeds and other plant material (including GE seeds and GE plant material) between our facilities in the U.S. and Canada, including USDA-APHIS and CFIA permits for the import and phytosanitary certificates for the export of plant materials that could pose a risk to domestic agriculture.

Having deployed our own research and development operations in Saskatoon, Canada in 2010, we have been conducting field studies of various yield traits in that country since 2016 under PNT permits issued by Canadian regulators. During 2018, we conducted field studies of C3003 in canola, Camelina and soybean at field sites in Canada.

Finally, as one of Canada’s major field crops, canola in particular is subject to variety registration, which is a regulatory requirement of the Seeds Act and is also administered by the CFIA. Any future sales of our seed traits or products in Canada would be done by a third-party collaborator or other partner, and that third party would be responsible for complying with registration requirements for the canola varieties, if applicable.

Regulation in Other Jurisdictions

Further, although U.S. and Canadian regulatory authorities have taken similar approaches to overseeing both traditional biotechnology-derived plants and genome edited plants under their national plant health and biosafety laws, regulation of all GE plants in the EU is significantly more stringent than in North America. U.S. and Canadian regulators have also determined that genome edited GE plants pose fewer risks that those subjected to Traditional Genome Modification, while a recent EU legal ruling indicates that the existing European regulations for GE plants modified by the insertion of recombinant DNA should be strictly applied to genome edited plants at well. There is thus a sharp distinction between how European and North American regulatory agencies oversee novel seed traits, including those that

are generated using the more modern techniques of genome editing. It is possible that emerging oversight regimes for GE products in other jurisdictions could follow the EU approach and impose similar strict requirements for the release of such products into the environment and their incorporation into human food or other consumer products.

Regulation of biotechnology-derived products in the EU is primarily based on Directive 2001/18/EC (the “2001 EC Directive”). The 2001 EC Directive defines “genetically modified organisms” ("GMOs") broadly as “organism[s], with the exception of human beings, in which the genetic material has been altered in a way that does not occur naturally by mating and/or natural recombination.” In July 2018, the Court of Justice of the European Union (CJEU) issued an important ruling clarifying that the 2001 EC Directive and its pre-market authorization and associated risk assessment requirements required for such “GMOs” should also apply in full to organisms developed using more modern “directed” mutagenesis techniques.

The July 2018 CJEU decision is being interpreted to cover all modern genome editing tools such as CRISPR-Cas9, TALEN and oligonucleotide-directed mutagenesis. This recent clarification by the CJEU regarding the scope of EU regulations suggests that novel seed trait developers who are seeking to bring genome edited seed traits to commercial markets in the EU will face hurdles comparable to what has historically been required in Europe for introducing and commercializing Traditional Genome Modification traits.

Although we are not currently targeting European markets for the development or commercialization of our products, the EU approach to regulating GE plants without regard to the scientific distinctions between Traditional Genome Modification and directed genome editing could be adopted by emerging oversight regimes for GE products in other jurisdictions. There is no guarantee that countries for which we may have or may develop future marketing plans would not take a stricter legal and regulatory approach to controlling GE plants similar to that of the EU.

License Agreement with the University of Massachusetts

Pursuant to a license agreement with the University of Massachusetts ("UMASS") dated as of June 30, 2015, we have an exclusive, worldwide license under certain patents and patent applications, including issued patents covering our yield trait gene C3003, relating to the manufacture of plants with enhanced photosynthesis. The agreement provides an exclusive, worldwide license to make, have made, use, offer for sale, sell, have sold and import any transgenic plant seed or plant grown therefrom or transgenic plant material developed for sale to a farmer or grower for planting in the field, which transgenic plant seed or plant grown therefrom or transgenic plant material is covered by, embodies or is derived from (in whole or in part) one or more issued or pending claims of the licensed patents or patent applications.

We are required to use diligent efforts to develop licensed products throughout the field of use and to introduce licensed products into the commercial market. In that regard, we are obligated to fulfill certain development and regulatory milestones relating to C3003, including completion of multi-site field demonstrations of a crop species in which C3003 has been introduced, and filing for regulatory approval of a crop species in which C3003 has been introduced within a specified period. Our failure to achieve any milestone provided for under the agreement would, if we are unable to reach agreement with UMASS as to a potential adjustment of the applicable milestone, give UMASS the right to terminate the agreement, following a notice period.

We are obligated to pay UMASS milestone payments relating to any regulatory filings and approvals covered by the agreement, royalties on any sales of licensed products following regulatory approval, as well as a percentage of any sublicense income related to the licensed products.

We may terminate the agreement at any time upon 90 days prior written notice to UMASS. Either party may terminate for material breach immediately upon written notice for a breach that is not cured within 60 days after receiving written notice of the breach. In addition, UMASS may terminate this agreement with respect to certain patent rights immediately upon written notice in the event we contest the validity or enforceability of such patent rights.

License Agreement with the University of Missouri

Pursuant to a license agreement with the University of Missouri (“UM”) dated as of May 17, 2018, we have an exclusive, worldwide license to two novel gene technologies to boost oil content in crops. Both technologies are based on significant new discoveries around the function and regulation of Acetyl-CoA carboxylase (“ACCase”), a key rate-limiting enzyme involved in oil production. The first technology, named C3007, is a gene for a negative controller that inhibits the enzyme activity of ACCase. The second technology, named C3010, is a gene which, if over-expressed, results in increased activity of ACCase. The UM license was expanded during May 2019 to include an exclusive worldwide license to a third gene in the ACCase complex, that we have designated C3012, that may complement the activity of C3007 to boost oil content in crops.

We are required to use diligent efforts to develop licensed products throughout the licensed field and to introduce licensed products into the commercial market. In that regard, we are obligated to fulfill certain research, development and regulatory milestones relating to C3007, C3010 and C3012, including completion of multi-site field demonstrations of a crop species in which C3007, C3010 and C3012 have been introduced, and filing for regulatory approval of a crop species in which C3007, C3010 and C3012 have been introduced within a specified period. Our failure to achieve any milestone provided for under the license agreement would, if we are unable to reach agreement with UM as to a potential adjustment of the applicable milestone, give UM the right to terminate the license agreement or render it nonexclusive.

We are obligated to pay UM a license execution payment, milestone payments relating to any regulatory filings and approvals covered by the license agreement, royalties on any sales of licensed products following regulatory approval, as well as a percentage of any sublicense royalties related to the licensed products.

We may terminate the license agreement at any time upon 90 days’ prior written notice to UM. Either party may terminate the license agreement upon written notice for a breach that is not cured within 30 days after receiving written notice of the breach. In addition, UM may terminate the license agreement with respect to certain patent rights immediately upon written notice in the event we contest the validity or enforceability of such patent rights.

Agricultural Industry Landscape

Following advances in biotechnology in the 1970s through early 1990s, the first genetically modified ("GM") crops were commercially introduced in the U.S. in the years 1994 and 1995. Today, the U.S. leads the world in the adoption of GM crops in terms of crop value and acreage planted. GM crops have had both their supporters and their detractors over the years. Consumer sentiment including concerns about the safety of GM crops have limited the introduction and adoption of GM crops in Europe. However, recent studies by the National Academy of Science continue to support the 20 year history of safe use of GM crops.

The International Service for the Acquisition of Agri-Biotech Applications (ISAAA), an industry research group, reported that 457 million acres worldwide were planted with GM crops in 2016, the most recent year where data is available. The planting of GM crops is centered in the Americas with North America at approximately 45 percent of the acres and South America at approximately 43 percent. China and India follow with approximately 8 percent and the balance of the total worldwide GM crop acreage in 2016 was planted in the EU and the rest of world. The primary GM crops in the U.S. are corn, soybean, cotton and sugar beet. In Canada, the oilseed crop canola is the primary GM crop. Cotton is the primary GM crop grown in India and China.

In contrast to the Americas, the EU has been resistant to the adoption of GM crops and has relied heavily on plant breeding programs for capturing crop yield improvements over the last 20 years. In 2016, Spain was the largest producer of GM crops in Europe, based on cultivation of GM corn representing approximately 20 percent of the country’s crop that year. Certain GM crops have been approved for cultivation in some European countries, while other countries have imposed outright bans on cultivation of GM crops.

According to the market research firm, Research and Markets, the total global seed business was estimated at $68 billion in 2017 and is projected to grow to more than $100 billion by 2022. According to an ISAAA report, the global GM seed business represented a $17.2 billion market in 2017 and biotech crops were grown on approximately 469 million acres that year. The traits being commercialized today by the agricultural industry mainly address crop protection, which involves preventing crop damage by weeds, insects and other pests that lower expected crop yield. As technology has advanced, “trait stacking,” or the practice of adding multiple traits to an elite plant line, has become commonplace as a strategy to protect yield. As the industry has developed, the practice of inter-licensing traits between research and development driven seed companies has led to a proliferation of branded seed products on the market today.

The GM seed business is dominated by large multinational companies and their subsidiaries including BASF, Bayer, DowDuPont, Syngenta and AgReliant. These companies have significant resources, experience and track records of successfully developing, testing and commercializing high performing seed lines as well as new traits for GM crops. They offer farmers conventional and biotechnology seeds as well as crop protection chemicals, biologicals, fertilizers and other products and technologies aimed at supporting the on-farm efficiency of managing crops in the field as well as managing the overall cost of crop production to successful harvest. Many of these companies were recently involved in consolidation of the sector with the DowDuPont merger, the acquisition of Syngenta by ChemChina, and the acquisition of Monsanto by Bayer in 2018.

Privately owned, U.S. retail seed companies play a key role in the industry by developing, marketing and selling high performing seed to U.S. farmers. These companies include Beck’s Hybrids and Stine Seed. These companies have capabilities in both biotechnology and plant breeding. They source traits from the multinational companies and input these

traits into elite plant germplasm to produce seeds optimized for a variety of soil, climate and field conditions. Both companies offer a broad arrange of GM corn and soybean products to their customers.

Recent advances in biotechnology including gene editing have led to the formation of companies focusing on yield trait discovery, biologicals for pest control, agbiome strategies and precision agriculture. There are startups, privately held and publicly traded companies involved in this space. Such companies include AgBiome, Arcadia Biosciences, Benson Hill Biosystems, BioCeres, Calyxt, Cibus, Evogene, Inari, Indigo, Kaiima, Marrone Bio Innovation, and Pairwise Plants, many of which have greater resources and experience than we have.

DILUTION

If you acquire shares of our common stock in this offering, your ownership interest will be diluted to the extent of the difference between the public offering price per share of our common stock and the pro forma net tangible book value per share of our common stock after this offering. Our historical net tangible book value of

common stock as of September 30, 2019 was $2.6 million, or $0.21 per share of common stock. Historical net tangible book value per share represents the amount of our total tangible assets less total liabilities, divided by the total number of shares of common stock outstanding.

The last reported sales price per share of our common stock on The Nasdaq Capital Market on November 4, 2019 was $0.36. After giving effect to the sale in this offering of common stock, Class A and Class B Units and shares of Series B Preferred Stock to be sold in the concurrent private placement, and assuming the issuance of all of the shares of common stock underlying the Series A Preferred Stock, and the Series B Preferred Stock at the assumed conversion price of $0.36 per Class A Unit and after deducting underwriting discounts and commissions and estimated offering expenses payable by us, our as adjusted net tangible book value would have been $11.2 million, or $0.29 per share of common stock. Assuming the completion of this offering, this represents an increase in net tangible book value of $0.08 per share to our existing stockholders and dilution of $0.07 per share to anyone who purchases securities in this offering. The following table illustrates this calculation on a per share basis:

The following table illustrates this per share dilution:



Public offering price per Class A Unit	$0.36
Historical net tangible book value per share as of September 30, 2019	$0.21
Change in net tangible book value per share attributable to this offering	$0.08
Pro forma net tangible book value per share after this offering	$0.29
Dilution per share to new investors in the offering	$(0.07)

The information discussed above is based on an assumed public offering price of $0.36 per Class A Unit, is illustrative only and will change based on actual pricing and other terms in this offering determined at pricing. The foregoing discussion and table does not take into account further dilution to investors in this offering that could occur upon the exercise of outstanding options and warrants, including the warrants offered in this offering, having a per share exercise price less than the public offering price per share in this offering. To the extent that options or warrants outstanding as of September 30, 2019, have been or may be exercised or other shares issued, investors purchasing securities in this offering may experience further dilution. The table and calculations set forth above are based on the number of shares of common stock outstanding as of September 30, 2019 and excludes the shares of common stock that may be issued under the warrants to be issued in this offering and also excludes:


•	2,484,475 of common stock issuable upon exercise of options to purchase our common stock outstanding as of September 30, 2019 at a weighted average exercise price of $4.49 per share;


•	25,180 shares of common stock reserved as of September 30, 2019 for future issuance under our 2018 Stock Option and Incentive Plan;


•	570,784 shares of common stock issuable upon exercise of warrants issued pursuant to the Securities Purchase Agreement we entered into with certain investors on July 3, 2017 (which warrants became exercisable on January 7, 2018 at an exercise price of $5.04 per share and expire on January 7, 2024);


•	30,000 shares of common stock issuable upon exercise of immediately vested warrants issued to an investor relations consultant on September 12, 2017 at an exercise price of $2.90 per share and which expire on September 11, 2024;


•	6,439,000 shares of common stock issuable upon exercise of vested Series A warrants outstanding as of September 30, 2019 pursuant to the Securities Purchase Agreement we entered into with certain investors on December 21, 2017 at an exercise price of $2.25 per share and which expire on December 21, 2022; and


•	Shares of common stock issuable upon exercise of the Series A Warrants and the Series B Warrants sold in this offering.

To the extent that options or warrants are exercised, there will be further dilution to new investors.

CONCURRENT PRIVATE PLACEMENT

The shares of Series B Preferred Stock are convertible into shares of our common stock at a conversion price equal to the public offering price of the Class A Units being sold pursuant to this prospectus, subject to customary anti-dilution adjustments. The underwriters have not agreed to nor will they purchase, sell and/or arrange for the purchase or sale of any of the shares of the Series B Preferred Stock nor will they receive any compensation in connection with any such sale. Following the closing of the offering and the concurrent private placement, we will seek stockholder approval of an amendment to our certificate of incorporation to implement an increase in the number of authorized shares of our common stock at a special meeting of stockholders to be called for this purpose. The Series B Preferred Stock that is being sold in the concurrent private placement will not be convertible into shares of common stock until the approval of the Charter Amendment. The Series B Preferred Stock will automatically convert into common stock on the date on which we publicly announce, through filing of a Current Report on Form 8-K, that we have sufficient authorized shares of common stock as a result of the Charter Amendment. We will also seek stockholder approval for the issuance by us in the concurrent private placement of the Series B Preferred Stock, Series A warrants and Series B warrants, as required by Nasdaq Marketplace Rule 5635(d), because we will be issuing securities convertible into our common stock at a discount to market price in an amount greater than 19.99% of our outstanding common stock.

Description of Securities Being Registered

We are offering Class A Units, with each Class A Unit consisting of one share of common stock and accompanying Series A Warrants and Series B Warrants, each at an exercise price per share of $[●], together with the shares of common stock underlying such warrants, at an assumed public offering price of $0.36 per Class A Unit. Each Series A Warrant and Series B Warrant included in the Class A Units entitles its holder to purchase a one share of common stock. The Series A Warrants included in the Class A Units will be exercisable for an aggregate total of 2,777,777 shares of common stock and the Series B Warrants included in the Class A Units will be exercisable for an aggregate total of 2,777,777 shares of common stock. The Class A Units will not be certificated

and the shares of common stock and warrants part of such units are immediately separable and will be issued separately in this offering.

We are also offering to those purchasers whose purchase of Class A Units in this offering would result in the purchaser, together with its affiliates and certain related parties, beneficially owning more than 4.99% (or, at the election of the purchaser, 9.99%) of our outstanding common stock following the consummation of this offering, the opportunity to purchase, in lieu of the number of Class A Units that would result in ownership in excess of 4.99% (or, at the election of the purchaser, 9.99%), Class B Units. Each Class B Unit will consist of one share of our Series A Preferred Stock, par value $0.01 per share, convertible into 2,777 shares of common stock, Series A Warrants to purchase 2,777 shares of common stock and Series B Warrants to purchase 2,777 shares of common stock (together with the shares of common stock underlying such shares of Series A Preferred Stock, such Series A Warrants and such Series B Warrants) at a public offering price of $1,000 per Class B Unit. Each Series A Warrant and Series B Warrant included in the Class B Units entitles its holder to purchase a number of shares equal to 100% of the common stock underlying each share of Series A Preferred Stock.

Based on a conversion price of our common stock of $0.36 per share, the Series A Preferred Stock included in the Class B Units will be convertible into an aggregate total of 11,108,000 shares of common stock, the Series A Warrants included in the Class B Units will be exercisable for an aggregate total of 11,108,000 shares of common stock and the Series B Warrants included in the Class B Units will be exercisable for an aggregate total of 11,108,000 shares of common stock. The Class B Units will not be certificated and the shares of Series A Preferred Stock and the warrants part of such units are immediately separable and will be issued separately in this offering. The Series A Preferred Stock will only be entitled to dividends in the event dividends are paid on our common stock and will not have voting rights or any preferences over common stock, including liquidation rights.

Description of Series A Preferred Stock Included in the Units

Our board of directors has designated 4,000 shares of our preferred stock as Series A Preferred Stock (“Series A Preferred Shares”), none of which are currently issued and outstanding. The preferences and rights of the Series A Preferred Shares will be as set forth in a Certificate of Designation (the “Series A Certificate of Designation”) filed as an exhibit to the registration statement of which this prospectus is a part.

In the event of a liquidation, the holders of Series A Preferred Shares are entitled to participate on an as-converted-to-Common Stock basis with holders of the Common Stock in any distribution of assets of the Company to the holders of the Common Stock. The Series A Certificate of Designation provides, among other things, that we shall not pay any dividends on shares of Common Stock (other than dividends in the form of Common Stock) unless and until such time as we pay dividends on each Series A Preferred Share on an as-converted basis. Other than as set forth in the previous sentence, the Series A Certificate of Designation provides that no other dividends shall be paid on Series A Preferred Shares and that we shall pay no dividends (other than dividends in the form of common stock) on shares of Common Stock unless we simultaneously comply with the previous sentence. The Series A Certificate of Designation does not provide for any restriction on the repurchase of Series A Preferred Shares by us while there is any arrearage in the payment of dividends on the Series A Preferred Shares. There are no sinking fund provisions applicable to the Series A Preferred Shares.

With certain exceptions, as described in the Series A Certificate of Designation, the Series A Preferred Stock has no voting rights. However, as long as any shares of Series A Preferred Stock remain outstanding, the Series A Certificate of Designation provides that we shall not, without the affirmative vote of holders of a majority of the then-outstanding Series A Preferred Stock, (a) alter or change adversely the powers, preferences or rights given to the Series A Preferred Stock or alter or amend the Series A Certificate of Designation, (b) increase the number of authorized shares of Series A Preferred Stock or (c) effect a stock split or reverse stock split of the Series A Preferred Stock or any like event.

Each share of Series A Preferred Stock is convertible at any time at the holder’s option into a number of shares of common stock equal to $1,000.00 divided by the assumed Conversion Price of $0.36. The Conversion Price is subject to adjustment for stock splits, stock dividends, distributions, subdivisions and combinations. Notwithstanding the foregoing, the Series A Certificate of Designation further provides that we shall not effect any conversion of Series A Preferred Stock, with certain exceptions, to the extent that, after giving effect to an attempted

conversion, the holder of Series A Preferred Shares (together with such holder’s affiliates, and any persons acting as a group together with such holder or any of such holder’s affiliates) would beneficially own a number of shares of Common Stock in excess of 4.99% (or, at the election of the holder prior to the date of issuance, 9.99%) of the shares of our Common Stock then outstanding after giving effect to such exercise (the “Preferred Stock Beneficial Ownership Limitation”); provided, however, that upon notice to the Company, the holder may increase or decrease the Preferred Stock Beneficial Ownership Limitation, provided that in no event shall the Preferred Stock Beneficial Ownership Limitation exceed 9.99% and any increase in the Preferred Stock Beneficial Ownership Limitation will not be effective until 61 days following notice of such increase from the holder to us.

Subject to certain conditions, at any time following the issuance of the Series A Preferred Stock, we will have the right to cause each holder of the Series A Preferred Stock to convert all or part of such holder’s Series A Preferred Stock in the event that (i) the volume weighted average price of our common stock for 30 consecutive trading days (the “Measurement Period”) exceeds 300% of the initial conversion price of the Series A Preferred Stock (subject to adjustment for forward and reverse stock splits, recapitalizations, stock dividends and similar transactions), (ii) the daily trading volume on each Trading Day during such Measurement Period exceeds $175,000 per trading day and (iii) the holder is not in possession of any information that constitutes or might constitute, material non-public information which was provided by us. Our right to cause each holder of the Series A Preferred Stock to convert all or part of such holder’s Series A Preferred Stock shall be exercised ratably among the holders of the then outstanding preferred stock.

We do not intend to apply for listing of the Series A Preferred Stock on any securities exchange or other trading system.

Description of Warrants Included in the Units

The material terms and provisions of the warrants being offered pursuant to this prospectus are summarized below. This summary of some provisions of the warrants is not complete. For the complete terms of the warrants, you should refer to the form of warrant to be filed as an exhibit to the registration statement of which this prospectus is a part.

Each Unit will be issued with: (a) one Series A Warrant, which may be exercised starting on the date on which we publicly announce, through the filing of a Current Report on Form 8-K, that we have sufficient authorized shares of common stock to allow the full exercise of the warrants, until two and one half years after the closing of this offering, and (b) one Series B Warrant, which may be exercised starting on the date on which we publicly announce, through the filing of a Current Report on Form 8-K, that we have sufficient authorized shares of common stock to allow the full exercise of the warrants, until seven and one half years after the date of the closing of this offering. Each whole warrant is exercisable to purchase one share of our common stock at an exercise price of $[●] per share at any time prior to expiration.

The holder of a warrant will not be deemed a holder of our underlying common stock until the warrant is exercised. Pursuant to a warrant agency agreement between us and American Stock Transfer & Trust Company, LLC, as warrant agent, the warrants will be issued in book-entry form and shall initially be represented only by one or more global warrants deposited with the warrant agent, as custodian on behalf of the Depository Trust Company, or DTC, and registered in the name of Cede & Co., a nominee of DTC, or as otherwise directed by DTC.

Subject to limited exceptions, a holder of warrants will not have the right to exercise any portion of its warrants if the holder (together with such holder’s affiliates, and any persons acting as a group together with such holder or any of such holder’s affiliates) would beneficially own a number of shares of common stock in excess of 4.99% (or, at the election of the purchaser prior to the date of issuance, 9.99%) of the shares of our Common Stock then outstanding after giving effect to such exercise (the "Beneficial Ownership Limitation"): provided, however, that upon notice to the Company, the holder may increase or decrease the Preferred Stock Beneficial Ownership Limitation, provided that in no event shall the Beneficial Ownership Limitation exceed 9.99% and any increase in the Beneficial Ownership Limitation will not be effective until 61 days following notice of such increase from the holder to us.

The exercise price and the number of shares issuable upon exercise of the warrants is subject to appropriate adjustment in the event of recapitalization events, stock dividends, stock splits, stock combinations, reclassifications, reorganizations or similar events affecting our common stock. The warrant holders must pay the exercise price in cash upon exercise of the warrants, unless such warrant holders are utilizing the cashless exercise provision of the warrants. On the expiration date, unexercised warrants will automatically be exercised via the “cashless” exercise provision.

Upon the holder’s exercise of a warrant, we will issue the shares of common stock issuable upon exercise of the warrant within two trading days following our receipt of a notice of exercise, provided that payment of the exercise price has been made (unless exercised to the extent permitted via the “cashless” exercise provision). Prior to the exercise of any warrants to purchase common stock, holders of the warrants will not have any of the rights of holders of the common stock purchasable upon exercise, including the right to vote, except as set forth therein. Warrant holders may exercise warrants only if the issuance of the shares of common stock upon exercise of the warrants is covered by an effective registration statement, or an exemption from registration is available under the Securities Act and the securities laws of the state in which the holder resides. We intend to use commercially reasonable efforts to have the registration statement, of which this prospectus forms a part, effective when the warrants are exercised. The warrant holders must pay the exercise price in cash upon exercise of the warrants unless there is not an effective registration statement or, if required, there is not an effective state law registration or exemption covering the issuance of the shares underlying the warrants (in which case, the warrants may only be exercised via a “cashless” exercise provision).

We do not currently have a sufficient number of authorized shares of common stock to cover shares issuable upon exercise of the warrants being offered by this prospectus. As a result, before any warrants can become exercisable, we will seek stockholder approval of an amendment to our certificate of incorporation to implement an increase in the number of authorized shares of our common stock at a special meeting of stockholders to be called for this purpose. While our board of directors will unanimously recommend that stockholders approve the Charter Amendment, we cannot assure you that we will be able to obtain the requisite stockholder approval of the Charter Amendment. The warrants will be exercisable on any day on or after the date on which we publicly announce, through filing of a Current Report on Form 8-K, that we have sufficient authorized shares of common stock as a result of the Charter Amendment.

Further, as more fully described in the warrants, in the event of certain fundamental transactions involving the Company, including a merger, each holder of a warrant will be entitled, at any time within 30 days of the consummation of such fundamental transaction (or, if later, the date of the public announcement of the applicable fundamental transaction), to require the Company to purchase its warrant and receive consideration in an amount equal to the Black-Scholes value of the remaining unexercised portion of the warrant on the date of the consummation of such fundamental transaction; provided, however, that if the fundamental transaction is not within the Company’s control, the holder of the warrant shall only be entitled to receive from the Company or any successor entity, as of the date of the consummation of the fundamental transaction, the same type or form of consideration (and in the same proportion), at the Black-Scholes value of the unexercised portion of the warrant, that is being offered and paid to the holders of our common stock in connection with the fundamental transaction, whether that consideration is in the form of cash, stock or any combination thereof, or whether the holders of common stock are given the choice to receive from among alternative forms of consideration in connection with the fundamental transaction.

The warrants are callable by us in certain circumstances. Subject to certain conditions, at any time following the date of issuance of the warrants, if (i) the volume weighted average price of our common stock for each of 20 consecutive trading days (the “Warrant Measurement Period”) exceeds 300% of the initial exercise price (subject to adjustment for forward and reverse stock splits, recapitalizations, stock dividends and similar transactions), (ii) the average daily trading volume for such Warrant Measurement Period exceeds $175,000 per trading day and (iii) the holder is not in possession of any information that constitutes or might constitute, material non-public information which was provided by the Company, then we may, within one trading day of the end of such Measurement Period, upon notice (a “Call Notice”), call for cancellation of all or any portion of the warrants for which a notice of exercise has not yet been delivered for consideration equal to $0.001 per share. Any portion of a warrant subject to such Call Notice for which a notice of exercise shall not have been received by the Call Date (as

hereinafter defined) will be canceled at 6:30 p.m. (New York City time) on the tenth trading day after the date the Call Notice is received by the holder (such date and time, the “Call Date”). Our right to call the warrants shall be exercised ratably among the holders based on the outstanding warrants.

We do not intend to apply for listing of the warrants on any securities exchange or other trading system.

Concurrent Private Placement

Concurrently with this offering of securities pursuant to this prospectus, we are offering to sell to Jack W. Schuler, our largest shareholder, and entities related to him up to $4.6 million of our Series B Convertible Preferred Stock, Series A warrants and Series B warrants pursuant to a concurrent private placement. Such shares and warrants will only be convertible into common stock upon receipt of shareholder approval of an increase in our authorized shares at a stockholder meeting to be called for that purpose. Mr. Schuler and entities related to him have signed voting agreements committing to vote in favor of such amendment. While we have agreed to the terms of the concurrent private placement with Mr. Schuler, we cannot assure you that the concurrent private placement will be completed. Each share of our Series B Preferred Stock, par value $0.01 per share, will convert into 2,777 shares of common stock upon the approval of the Charter Amendment. The concurrent private placement also includes Series A Warrants to purchase 2,777 shares of common stock and Series B Warrants to purchase 2,777 shares of common stock. The Series A Warrants to be sold in the concurrent private placement entitle the holder to purchase a number of shares equal to 100% of the common stock underlying each share of Series B Preferred Stock. The Series B Warrants to be sold in the concurrent private placement entitle the holder to purchase a number of shares equal to 100% of the common stock underlying each share of Series B Preferred Stock.

The Series B Preferred Stock will not be convertible into shares of common stock until the approval of the Charter Amendment. Based on an assumed conversion price of our common stock of $0.36 per share, the Series B Preferred Stock will be convertible into an aggregate total of 12,774,200 shares of common stock, the Series A Warrants to be sold in the concurrent private placement will be exercisable for an aggregate total of 12,774,200 shares of common stock and the Series B Warrants to be sold in the concurrent private placement will be exercisable for an aggregate total of 12,774,200 shares of common stock. The Series B Preferred Stock will be entitled to dividends starting on March 31, 2020 if such shares remain outstanding at that time and will have certain other preferences as noted below under "Description of Series B Preferred Stock Included in the Units."

Description of Series B Preferred Stock to be Sold in the Concurrent Private Placement

Our board of directors has designated 4,600 shares of our preferred stock as Series B Preferred Stock (“Series B Preferred Shares”), none of which are currently issued and outstanding. The preferences and rights of the Series B Preferred Shares will be as set forth in a Certificate of Designation (the “Series B Certificate of Designation”) filed as an exhibit to the registration statement of which this prospectus is a part.

In the event of a liquidation, the holders of Series B Preferred Shares have a liquidation preference, such that in the event of a liquidation of the company, holders of the Series B Preferred Stock would be paid $1,000.00 per share of Series B Preferred Stock plus the amount of the accrued dividends (as described below) to the point of liquidation, prior to any payment to holders of junior securities, including the common stock. The Series B Preferred Shares have a cumulative quarterly dividend right, payable starting March 31, 2020, pursuant to which the holders of Series B Preferred Shares will be entitled to receive a dividend equal initially to (i) 2% of the state value of the Series B Preferred Shares plus (ii) all accrued and unpaid dividends, which dividends are payable in additional Series B Preferred Shares. The dividend rate will increase by 2% on each quarterly dividend payment date for as long as the Series B Preferred Shares remain outstanding.The Series B Certificate of Designation does not provide for any restriction on the repurchase of Series B Preferred Shares by us while there is any arrearage in the payment of dividends on the Series B Preferred Shares. There are no sinking fund provisions applicable to the Series B Preferred Shares.

With certain exceptions, as described in the Series B Certificate of Designation, the Series B Preferred Stock has no voting rights. However, as long as any shares of Series B Preferred Stock remain outstanding, the Series B Certificate of Designation provides that we shall not, without the affirmative vote of holders of a majority

of the then-outstanding Series B Preferred Stock, (a) alter or change adversely the powers, preferences or rights given to the Series B Preferred Stock or alter or amend the Series B Certificate of Designation, (b) increase the number of authorized shares of Series B Preferred Stock or (c) effect a stock split or reverse stock split of the Series B Preferred Stock or any like event. The holders of the Series B Preferred Stock will also have the right to approve specified corporate transactions, including the issuance of any securities that would be senior to the Series B Preferred Stock, material changes in our business, material acquisitions of assets, appointments of new executive officers, liquidations, repurchase of shares, and other matters as set forth in the Series B Certificate of Designation.

The Series B Preferred Stock will not be convertible into shares of common stock until the approval of the Charter Amendment. While our board of directors will unanimously recommend that stockholders approve the Charter Amendment, we cannot assure you that we will be able to obtain the requisite stockholder approval of the Charter Amendment. The Series B Preferred Stock will automatically convert into common stock on the date on which we publicly announce, through filing of a Current Report on Form 8-K, that we have sufficient authorized shares of common stock as a result of the Charter Amendment. Each share of Series B Preferred Stock will convert into a number of shares of common stock equal to $1,000.00 divided by the assumed Conversion Price. The Conversion Price is subject to adjustment for stock splits, stock dividends, distributions, subdivisions and combinations.

The holders of the Series B Preferred Stock have the ability to demand that we register the shares of common stock underlying the Series B Preferred Stock and warrants issued to such holders no later than 15 business days after the receipt of the stockholder approval for the Charter Amendment.

Subject to certain conditions, at any time following the issuance of the Series B Preferred Stock, we will have the right to cause each holder of the Series B Preferred Stock to convert all or part of such holder’s Series B Preferred Stock in the event that (i) the volume weighted average price of our common stock for 30 consecutive trading days (the “Measurement Period”) exceeds 300% of the initial conversion price of the Series B Preferred Stock (subject to adjustment for forward and reverse stock splits, recapitalizations, stock dividends and similar transactions), (ii) the daily trading volume on each Trading Day during such Measurement Period exceeds $175,000 per trading day and (iii) the holder is not in possession of any information that constitutes or might constitute, material non-public information which was provided by us. Our right to cause each holder of the Series B Preferred Stock to convert all or part of such holder’s Series B Preferred Stock shall be exercised ratably among the holders of the then outstanding preferred stock.

We do not intend to apply for listing of the Series B Preferred Stock on any securities exchange or other trading system.

Common Stock

The holders of our common stock are entitled to one vote per share on all matters submitted to a vote of our stockholders and do not have cumulative voting rights. Subject to preferences that may be applicable to any preferred stock outstanding at the time, the holders of outstanding shares of common stock are entitled to receive ratably any dividends declared by our board of directors out of assets legally available. Upon our liquidation, dissolution or winding up, holders of our common stock are entitled to share ratably in all assets remaining after payment of liabilities and the liquidation preference of any then outstanding shares of preferred stock. Holders of common stock have no preemptive or conversion rights or other subscription rights. There are no redemption or sinking fund provisions applicable to our common stock.

Preferred Stock

Our amended and restated certificate of incorporation, as amended, authorizes it to issue up to 5,000,000 shares of $0.01 par value undesignated preferred stock. Our board of directors may designate the rights, preferences, privileges and restrictions of the preferred stock, including dividend rights, conversion rights, voting rights, terms of redemption, liquidation preference, sinking fund terms and the number of shares constituting any series or the designation of any series. As of September 30, 2019, no preferred stock was issued or outstanding.

Warrants

As of September 30, 2019, we had warrants outstanding to purchase 7,039,784 shares of our common stock.

Anti-Takeover Provisions

Certain provisions of the DGCL and our amended and restated certificate of incorporation, as amended, and amended and restated by-laws may have the effect of delaying, deferring or discouraging another party from acquiring control of our company. These provisions, which are summarized below, may discourage certain types of coercive takeover practices and inadequate takeover bids and encourage anyone seeking to acquire control of our company to first negotiate with our board of directors. These provisions might also have the effect of preventing changes in our management and could make it more difficult to accomplish transactions that stockholders might otherwise deem to be in their best interests. However, we believe that the advantages gained by protecting our ability to negotiate with any unsolicited and potentially unfriendly acquirer outweigh the disadvantages of discouraging such proposals, because, among other reasons, the negotiation of such proposals could result in improving their terms.

Amended and Restated Certificate of Incorporation and By-law Provisions

Our amended and restated certificate of incorporation, as amended, and amended and restated by-laws include a number of provisions that may have the effect of delaying, deferring or discouraging another party from acquiring control of our company or preventing changes in our management, including the following:

•

Issuance of Undesignated Preferred Stock. Our board of directors has the authority, without further action by the stockholders, to issue up to 5,000,000 shares of undesignated preferred stock with rights, preferences and privileges designated from time to time by our board of directors without further action by stockholders. These rights, preferences and privileges could include dividend rights, conversion rights, voting rights, terms of redemption, liquidation preferences and sinking fund terms, any or all of which may be greater than the rights of common stock.

•

Size of the Board of Directors and Filling Vacancies. The number of directors constituting our board of directors may be set only by resolution adopted by a majority vote of our entire board of directors. Any vacancy on our board of directors, however occurring, including a vacancy resulting from an increase in the size of the board of directors, may only be filled by the affirmative vote of a majority of our directors then in office, even if less than a quorum.


•	Classified Board. Our board of directors is divided into three classes of directors, with staggered three-year terms. Only one class of directors will be elected at each annual meeting of our stockholders, with the other classes continuing for the remainder of their respective three-year terms.


•	No Cumulative Voting. Our amended and restated certificate of incorporation, as amended, and amended and restated by-laws do not permit cumulative voting in the election of directors. Cumulative voting allows a stockholder to vote a portion, or all of its shares for one or more candidates. The absence of cumulative voting makes it more difficult for a minority stockholder to gain a seat.


•	Removal of Directors. Directors can only be removed by our stockholders for cause and removal of a director will require a 75% stockholder vote.

•

No Written Consent of Stockholders. All stockholder actions are required to be taken by a vote of the stockholders at an annual or special meeting. Stockholders may not take action by written consent in lieu of a meeting. The inability of stockholders to take action by written consent means that a stockholder would need to wait until the next annual or special meeting to bring business before the stockholders for a vote.


•	Special Meetings of Stockholders. Special meetings of our stockholders may be called only by our board of directors acting pursuant to a resolution approved by the affirmative vote of a majority of the

directors then in office. Only those matters set forth in the notice of the special meeting may be considered or acted upon at a special meeting of our stockholders.

•

Advance Notice Requirements for Stockholder Proposals and Director Nominations. Our amended and restated by-laws provide advance notice procedures for stockholders seeking to bring business before our annual meeting of stockholders or to nominate candidates for election as directors at our annual meeting of stockholders. These procedures provide that notice must be given in writing not later than the close of business on the 90^th day nor earlier than the close of business on the 120^th day prior to the first anniversary of the preceding year’s annual meeting. These procedures may have the effect of precluding the conduct of certain business at a meeting if the proper procedures are not followed or may discourage or deter a potential acquirer from conducting a solicitation of proxies to elect its own slate of directors or otherwise attempt to obtain control of us.

•

Amendment to Amended and Restated Certificate of Incorporation and By-laws. Any amendment, repeal or modification of certain provisions of our amended and restated certificate of incorporation or amended and restated by-laws requires a 75% stockholder vote. Provisions requiring such supermajority vote include, among other things, any amendment, repeal or modification of the provisions relating to the classification of our board of directors, the requirement that stockholder actions be effected at a duly called annual or special meeting of our stockholders and the designated parties entitled to call a special meeting of our stockholders.

Section 203 of the DGCL

We are subject to Section 203 of the DGCL. In general, Section 203 of the DGCL prohibits a publicly held Delaware corporation from engaging in a “business combination” with an “interested stockholder” for a three-year period following the time that this stockholder becomes an interested stockholder, unless it satisfies one of the following conditions:


•	the transaction is approved by the board of directors prior to the time that the interested stockholder became an interested stockholder;


•	upon consummation of the transaction which resulted in the stockholder becoming an interested stockholder, the interested stockholder owned at least 85% of the voting stock of the corporation outstanding at the time the transaction commenced; or

In general, Section 203 defines “business combination” to include the following:


•	at or subsequent to such time that the stockholder became an interested stockholder, the business combination was approved by the board of directors and authorized at an annual or special meeting of stockholders by at least two-thirds of the outstanding voting stock which is not owned by the interested stockholder.


•	any merger or consolidation involving the corporation and the interested stockholder;


•	any sale, lease, exchange, mortgage, pledge, transfer or other disposition of the assets of the corporation with an aggregate market value of 10% or more of either the aggregate market value of all assets of the corporation on a consolidated basis or the aggregate market value of all of the outstanding stock of the corporation involving the interested stockholder;


•	subject to certain exceptions, any transaction that results in the issuance or transfer by the corporation of any stock of the corporation to the interested stockholder;


•	any transaction involving the corporation that has the effect of increasing the proportionate share of the stock or any class or series of the corporation beneficially owned by the interested stockholder; or


•	the receipt by the interested stockholder of the benefit of any loans, advances, guarantees, pledges or other financial benefits by or through the corporation.

In general, Section 203 defines an “interested stockholder” as an entity or person who, together with the stockholder’s affiliates and associates (as defined in Section 203), beneficially owns, or within three years prior to the time of determination of interested stockholder status did own, 15% or more of the outstanding voting stock of the corporation.

Treatment of Options Upon Change of Control

In general, under the terms of our Stock Option and Incentive Plans and our Stock Issuance Plan and our executive employment agreements, in the event of certain change in control transactions, if the successor corporation does not assume our outstanding options or issue replacement awards, or if an option holder’s employment is involuntarily terminated in connection with such change in control, the vesting of the options outstanding under such plans will accelerate.

Ladenburg Thalmann & Co., Inc.	[•]	[•]
Total	[•]	[•]

A copy of the underwriting agreement will be filed as an exhibit to the registration statement of which this prospectus is a part.

We have been advised by the underwriters that they propose to offer the units directly to the public at the public offering price set forth on the cover page of this prospectus. Any securities sold by the underwriters to securities dealers will be sold at the public offering price less a selling concession not in excess of $[●] per share and $[●] per warrant. The underwriting agreement provides that the underwriters' obligation to purchase the securities we are offering is subject to conditions contained in the underwriting agreement.

No action has been taken by us or the underwriters that would permit a public offering of the units, or the shares of common stock, shares of preferred stock and warrants included in the units, in any jurisdiction outside the United States where action for that purpose is required. None of our securities included in this offering may be offered or sold, directly or indirectly, nor may this prospectus or any other offering material or advertisements in connection with the offer and sales of any of the securities offering hereby be distributed or published in any jurisdiction except under circumstances that will result in compliance with the applicable rules and regulations of that jurisdiction. Persons who receive this prospectus are advised to inform themselves about and to observe any restrictions relating to this offering of securities and the distribution of this prospectus. This prospectus is neither an offer to sell nor a solicitation of any offer to buy the securities in any jurisdiction where that would not be permitted or legal.

The underwriters have advised us that they do not intend to confirm sales to any account over which they exercise discretionary authority.

Underwriting Discount and Expenses

The following table summarizes the underwriting discount and commission to be paid to the underwriters by us.



	Per Class A Unit ⁽¹⁾	Per Class B Unit ⁽¹⁾	Total	Total Including Over-Allotment⁽²⁾
Public offering price	$ [•]	$ [•]	$ [•]	$ [•]
Underwriting discount and commissions to be paid to the underwriters by us ⁽³⁾	$ [•]	$ [•]	$ [•]	$ [•]
Proceeds, before expenses, to us	$ [•]	$ [•]	$ [•]	$ [•]

________________



(1)	The public offering price and underwriting discount corresponds to (x) in respect of the Class A Units (i) a public offering price per share of common stock of $[•] ($[•] net of underwriting discount), (ii) a public offering price per Series A Warrant of $0.01 ($[•] net of the underwriting discount), and (iii) a public offering price per Series B Warrant of $0.01 ($[•] net of the underwriting discount) and (y) in respect of the Class B Units (i) a public offering price per share of Series A Preferred Stock of $[•] ($[•] net of underwriting discount) and (ii) a public offering price per Series A Warrant of $0.01 ($[•] net of the underwriting discount), and (iii) a public offering price per Series B Warrant of $0.01 ($[•] net of the underwriting discount).

(2)	We have granted the representative an option, which is exercisable not later than 45 days after the date of this prospectus, to purchase a number of additional shares of common stock in an amount that is up to 15% of the number of shares of common stock sold in the primary offering (which number includes the number of shares of common stock issuable upon conversion of shares of the Series A Preferred Stock, but excludes any shares of common stock underlying the warrants issued in this offering, and any shares of common stock issued upon any exercise of the over-allotment option). These shares would be sold to the representative at the public offering price per share of common stock sold in the primary offering, less the underwriting discounts and commissions. Further, the option we have granted to the representative is also exercisable not later than 45 days after the date of this prospectus to purchase a number of additional warrants in an amount that is up to 15% of the warrants sold in the primary offering at the public offering price per warrant set forth on the cover page hereto (which is $0.01 per warrant), less the underwriting discounts and commissions. The representative may exercise the option to cover over-allotments, if any, made in connection with this offering. If any additional shares of common stock and/or warrants are purchased from us under this over-allotment option, the representative will offer these shares of common stock and/or warrants on the same terms as those on which the other securities are being offered.

(3)	Underwriting discounts and commissions per Unit with respect to the sale of Units to the public will be 8% and underwriting discounts and commissions per Unit with respect to the sale of Units to certain Company investors and insiders will be 3%.

We estimate the total expenses payable by us for this offering and the concurrent private placement to be approximately $1,015,000, which amount includes (i) the underwriting discount of 8% per Unit with respect to the sale of Units to the public and 3% per Unit with respect to the sale of Units to certain Company insiders (8% per Unit with respect to the sale of Units to the public if the underwriters' over-allotment option is exercised in full); and (ii) reimbursement of the accountable expenses of the representative equal to $90,000 including the legal fees of the representative being paid by us and (iii) other estimated company expenses of approximately $349,000 which includes legal, accounting, and printing costs and various fees associated with the registration and listing of our shares. We will pay a 3% fee to the representative in connection with a portion of the units to be sold in the concurrent private placement, and will pay an 8% fee in connection with the remainder of those units.

The securities we are offering are being offered by the underwriters subject to certain conditions specified in the underwriting agreement.

Over-allotment Option

We have granted the representative an option, which is exercisable not later than 45 days after the date of this prospectus, to purchase a number of additional shares of common stock in an amount that is up to 15% of the number of shares of common stock sold in the primary offering (which number includes the number of shares of common stock issuable upon conversion of shares of the Series A Preferred Stock, but excludes any shares of common stock underlying the warrants issued in this offering, and any shares of common stock issued upon any exercise of the over-allotment option). These shares would be sold to the representative at the public offering price per share of common stock sold in the primary offering, less the underwriting discounts and commissions. Further, the option we have granted to the representative is also exercisable not later than 45 days after the date of this prospectus to purchase a number of additional warrants in an amount that is up to 15% of the warrants sold in the primary offering at the public offering price per warrant set forth on the cover page hereto (which is $0.01 per warrant), less the underwriting discounts and commissions. The representative may exercise the option to cover over-allotments, if any, made in connection with this offering. If any additional shares of common stock and/or warrants are purchased from us under this over-allotment option, the representative will offer these shares of common stock and/or warrants on the same terms as those on which the other securities are being offered.

Nasdaq Listing

Our common stock is currently traded on The Nasdaq Capital Market under the symbol “YTEN.” On November 4, 2019 the closing price of our common stock was $0.36 per share. We do not intend to apply for listing of the Series A Preferred Stock, Series B Preferred Stock or warrants on any securities exchange or other trading system.

Determination of Offering Price

The public offering price of the securities offered by this prospectus will be determined by negotiation between us and the underwriters. Among the factors considered in determining the public offering price of the units were:


•	our history and our prospects;


•	the industry in which we operate;


•	our past and present operating results;


•	the previous experience of our executive officers; and


•	the general condition of the securities markets at the time of this offering.

The offering price stated on the cover page of this prospectus should not be considered an indication of the actual value of the securities sold in this offering. That price is subject to change as a result of market conditions and other factors and we cannot assure you that the shares of common stock, Series A Preferred Stock, and warrants sold in this offering can be resold at or above the public offering price.

Lock-up Agreements and Other Lock-up Restrictions

Our officers, directors and each of their respective affiliates and associated persons have agreed with the representative to be subject to a lock-up period of 90 days following the date of this prospectus. This means that, during the applicable lock-up period, such persons may not offer for sale, contract to sell, sell, distribute, grant any option, right or warrant to purchase, pledge, hypothecate or otherwise dispose of, directly or indirectly, any shares of our common stock or any securities convertible into, or exercisable or exchangeable for, shares of our common stock. Certain limited transfers are permitted during the lock-up period if the transferee agrees to these lock-up restrictions. We have also agreed, in the underwriting agreement, to similar lock-up restrictions on the issuance and sale of our securities for a period of time following the closing of this offering, as described in the next paragraph, although we will be permitted to issue stock options or stock awards to directors, officers and employees under our existing plans. The representative may, in its sole discretion and without notice, waive the terms of any of these lock-up agreements.

We have agreed, in the underwriting agreement, to similar lock-up restrictions on the issuance and sale of our securities until the later of (1) 90 days following the closing of this offering and (2) 15 days after the date that the Charter Amendment is effective.

Stockholder Approval

We have agreed to hold a stockholders meeting no later than 60 days after the date of the underwriting agreement in order to seek stockholder approval for an amendment to our certificate of incorporation to increase the number of shares of common stock we are authorized to issue in an amount sufficient to permit the exercise in full of the warrants in accordance with their terms. In the event that we are unable to effect an increase in our authorized shares of common stock, the warrants will not be exercisable and will have no value.

Other Relationships

Upon completion of this offering, and subject to certain conditions, we have granted the representative a right of first refusal to act as lead or co-lead bookrunner or lead or co-lead placement agent in connection with any subsequent public or private offering of equity securities or other capital markets financing by us. This right of first refusal extends for 9 months from the closing date of this offering. The terms of any such engagement of the representative will be determined by separate agreement.

Stabilization, Short Positions and Penalty Bids

In order to facilitate the offering, the underwriters may engage in transactions that stabilize, maintain or otherwise affect the price of our shares of common stock. In connection with the offering, the underwriters may purchase and sell our shares of common stock in the open market. These transactions may include short sales, purchases on the open market to cover positions created by short sales and stabilizing transactions. Short sales involve the sale by the underwriters of a greater number of shares of common stock than they are required to purchase in the offering. "Covered" short sales are sales made in an amount not greater than the underwriters' option to purchase additional shares of common stock in the offering pursuant to the exercise of their over-allotment option to purchase additional shares of common stock and/or warrants. The underwriters may close out, or satisfy, any covered short position by either exercising the over-allotment option, in which case the shares of common stock or warrants would be purchased directly from us, or purchasing shares of common stock in the open market. Because none of our warrants, including those to be sold in this offering, are publicly listed for trading on a securities exchange, the underwriters would need to purchase warrants directly from us as part of an exercise of the over-allotment option in order to be able to deliver both of the components of the units that are being sold to the investors in the offering when closing out any covered short position. The underwriters will pay the same price for any exercise of the over-allotment options as the public offering price for the securities sold in this offering, less the underwriting discount. With respect to a share of common stock, this price will be $[•] per share, and with respect to a warrant, this price will be $[•] per warrant. In determining the source of shares of common stock that may be needed to close out a covered short position, the underwriters will consider, among other things, the price of common stock that is then available for purchase in the open market as compared to the price at which they may purchase shares of common stock directly from us through the over-allotment option. "Naked" short sales are sales in excess of the over-allotment option. The underwriters must close out any naked short position by purchasing shares of common stock in the open market. A naked short position is more likely to be created if the underwriters are concerned that there may be downward pressure on the price of our shares of common stock in the open market after pricing that could adversely affect investors who purchase in the offering.


•	Stabilizing transactions permit bids to purchase the underlying security so long as the stabilizing bids do not exceed a specific maximum.


•	Penalty bids permit the underwriters to reclaim a selling concession from a syndicate member when the securities originally sold by the syndicate member are purchased in a stabilizing or syndicate covering transaction to cover syndicate short positions.

These stabilizing transactions and penalty bids may have the effect of raising or maintaining the market prices of our securities or preventing or retarding a decline in the market prices of our securities. As a result the price of our common stock may be higher than the price that might otherwise exist in the open market. Neither we nor the underwriters make any representation or prediction as to the effect that the transactions described above may have on the price of our common stock. These transactions may be effected on Nasdaq, in the over-the-counter market or on any other trading market and, if commenced, may be discontinued at any time.

In connection with this offering, the underwriters also may engage in passive market making transactions in our common stock in accordance with Regulation M during a period before the commencement of offers or sales of shares of our common stock in this offering and extending through the completion of the distribution. In general, a passive market maker must display its bid at a price not in excess of the highest independent bid for that security. However, if all independent bids are lowered below the passive market maker’s bid that bid must then be lowered when specific purchase limits are exceeded. Passive market making may stabilize the market price of the securities at a level above that which might otherwise prevail in the open market and, if commenced, may be discontinued at any time.

Neither we, nor the underwriters make any representation or prediction as to the direction or magnitude of any effect that the transactions described above may have on the prices of our securities. In addition, neither we nor the underwriters make any representation that the underwriters will engage in these transactions or that any transactions, once commenced will not be discontinued without notice.

Indemnification

We have agreed to indemnify the underwriters against certain liabilities, including certain liabilities arising under the Securities Act or to contribute to payments that the underwriters may be required to make for these liabilities.

DISCLOSURE OF COMMISSION POSITION ON INDEMNIFICATION FOR SECURITIES ACT LIABILITIES

Insofar as indemnification for liabilities arising under the Securities Act may be permitted to directors, officers, and controlling persons of the registrant pursuant to the foregoing provisions, or otherwise, the registrant has been informed that in the opinion of the SEC such indemnification is against public policy as expressed in the Securities Act and is, therefore, unenforceable.

Certain legal matters in connection with this offering will be passed upon for the underwriters by Ellenoff Grossman & Schole LLP, New York, New York.

Item 16. Exhibits and Financial Statement Schedules.

See Exhibit Index following the signature page to this Registration Statement.

Item 17. Undertakings.

The undersigned registrant hereby undertakes:

(1) To file, during any period in which offers or sales are being made, a post-effective amendment to this registration statement:

(i) To include any prospectus required by Section 10(a)(3) of the Securities Act;

(ii) To reflect in the prospectus any facts or events arising after the effective date of the registration statement (or the most recent post-effective amendment thereof) which, individually or in the aggregate, represent a fundamental change in the information set forth in the registration statement. Notwithstanding the foregoing, any increase or decrease in volume of securities offered (if the total dollar value of securities offered would not exceed that which was registered) and any deviation from the low or high end of the estimated maximum offering range may be reflected in the form of prospectus filed with the Commission pursuant to Rule 424(b) if, in the aggregate, the changes in volume and price represent no more than a 20 percent change in the maximum aggregate offering price set forth in the “Calculation of Registration Fee” table in the effective registration statement.

(iii) To include any material information with respect to the plan of distribution not previously disclosed in the registration statement or any material change to such information in the registration statement;

(2) That, for the purpose of determining any liability under the Securities Act, each such post-effective amendment shall be deemed to be a new registration statement relating to the securities offered therein, and the offering of such securities at that time shall be deemed to be the initial bona fide offering thereof.

(3) To remove from registration by means of a post-effective amendment any of the securities being registered which remain unsold at the termination of the offering.

(4) That, for the purpose of determining liability under the Securities Act to any purchaser: each prospectus filed pursuant to Rule 424(b) as part of a registration statement relating to an offering, other than registration statements relying on Rule 430B or other than prospectuses filed in reliance on Rule 430A, shall be deemed to be part of and included in the registration statement as of the date it is first used after effectiveness; provided, however, that no statement made in a registration statement or prospectus that is part of the registration statement or made in a document incorporated or deemed incorporated by reference into the registration statement or prospectus that is part of the registration statement will, as to a purchaser with a time of contract of sale prior to such first use, supersede or modify any statement that was made in the registration statement or prospectus that was part of the registration statement or made in any such document immediately prior to such date of first use.

(5) Insofar as indemnification for liabilities arising under the Securities Act may be permitted to directors, officers, and controlling persons of the registrant pursuant to the foregoing provisions, or otherwise, the registrant has been advised that in the opinion of the SEC such indemnification is against public policy as expressed in the Securities Act and is, therefore, unenforceable. In the event that a claim for indemnification against such liabilities (other than the payment by the registrant of expenses incurred or paid by a director, officer or controlling person of the registrant in the successful defense of any action, suit or proceeding) is asserted by such director, officer or controlling person in connection with the securities being registered, the registrant will, unless in the opinion of its counsel the matter has been settled by controlling precedent, submit to a court of appropriate jurisdiction the question whether such indemnification by it is against public policy as expressed in the Act and will be governed by the final adjudication of such issue.

3.1Representations and Warranties of the Company. The Company represents and warrants to the Underwriters as of the Execution Date, as of the Closing Date and as of each Option Closing Date, if any, as follows:

(a)Subsidiaries. All of the direct and indirect Subsidiaries of the Company are set forth in the SEC Reports. The Company owns, directly or indirectly, all of the capital stock or other equity interests of each Subsidiary free and clear of any Liens, and all of the issued and outstanding shares of capital stock of each Subsidiary are validly issued and are fully paid, non-assessable and free of preemptive and similar rights to subscribe for or purchase securities. If the Company has no Subsidiaries, all other references to the Subsidiaries or any of them in the Transaction Documents shall be disregarded.

(b)Organization and Qualification. The Company and each of the Subsidiaries is an entity duly incorporated or otherwise organized, validly existing

and in good standing under the laws of the jurisdiction of its incorporation or organization, with the requisite power and authority to own and use its properties and assets and to carry on its business as currently conducted. Neither the Company nor any Subsidiary is in violation nor default of any of the provisions of its respective certificate or articles of incorporation, bylaws or other organizational or charter documents. Each of the Company and the Subsidiaries is duly qualified to conduct business and is in good standing as a foreign corporation or other entity in each jurisdiction in which the nature of the business conducted or property owned by it makes such qualification necessary, except where the failure to be so qualified or in good standing, as the case may be, could not have or reasonably be expected to result in a Material Adverse Effect and no Proceeding has been instituted in any such jurisdiction revoking, limiting or curtailing or seeking to revoke, limit or curtail such power and authority or qualification.

(c)Authorization; Enforcement. The Company has the requisite corporate power and authority to enter into and to consummate the transactions contemplated by this Agreement and each of the other Transaction Documents and otherwise to carry out its obligations hereunder and thereunder. The execution and delivery of this Agreement and each of the other Transaction Documents by the Company and the consummation by it of the transactions contemplated hereby and thereby have been duly authorized by all necessary action on the part of the Company and no further action is required by the Company, the Board of Directors or the Company’s stockholders in connection herewith or therewith other than in connection with the Required Approvals. This Agreement and each other Transaction Document to which it is a party has been (or upon delivery will have been) duly executed by the Company and, when delivered in accordance with the terms hereof and thereof, will constitute the valid and binding obligation of the Company enforceable against the Company in accordance with its terms, except (i) as limited by general equitable principles and applicable bankruptcy, insolvency, reorganization, moratorium and other laws of general application affecting enforcement of creditors’ rights generally, (ii) as limited by laws relating to the availability of specific performance, injunctive relief or other equitable remedies and (iii) insofar as indemnification and contribution provisions may be limited by applicable law.

(d)No Conflicts. The execution, delivery and performance by the Company of this Agreement and the other Transaction Documents to which it is a party, the issuance and sale of the Securities and the consummation by it of the transactions contemplated hereby and thereby do not and will not (i) conflict with or violate any provision of the Company’s or any Subsidiary’s certificate or articles of incorporation, bylaws or other organizational or charter documents, or (ii) conflict with, or constitute a default (or an event that with notice or lapse of time or both would become a default) under, or result in the creation of any Lien upon any of the properties or assets of the Company or any Subsidiary, or give to others any rights of termination, amendment, anti-dilution or similar adjustments, acceleration or

cancellation (with or without notice, lapse of time or both) of, any agreement, credit facility, debt or other instrument (evidencing a Company or Subsidiary debt or otherwise) or other understanding to which the Company or any Subsidiary is a party or by which any property or asset of the Company or any Subsidiary is bound or affected, or (iii) subject to the Required Approvals, conflict with or result in a violation of any law, rule, regulation, order, judgment, injunction, decree or other restriction of any court or governmental authority to which the Company or a Subsidiary is subject (including federal and state securities laws and regulations), or by which any property or asset of the Company or a Subsidiary is bound or affected; except in the case of each of clauses (ii) and (iii), such as could not have or reasonably be expected to result in a Material Adverse Effect.

(e)Filings, Consents and Approvals. The Company is not required to obtain any consent, waiver, authorization or order of, give any notice to, or make any filing or registration with, any court or other federal, state, local or other governmental authority or other Person in connection with the execution, delivery and performance by the Company of the Transaction Documents, other than: (i) the filing with the Commission of the Prospectus, (ii) application(s) to each applicable Trading Market for the listing of the Shares, Warrant Shares and Conversion Shares for trading thereon in the time and manner required thereby, and (iii) such filings as are required to be made under applicable state securities laws (collectively, the “Required Approvals”).

The Company has filed with the Commission the Registration Statement, including any related Prospectus or Prospectuses, for the registration of the Securities under the Securities Act, which Registration Statement has been prepared by the Company in all material respects in conformity with the requirements of the Securities Act and the rules and regulations of the Commission under the Securities Act. The Registration Statement has been declared effective by the Commission on the date hereof (the “Effective Date”) and was post-effectively amended by the Rule 462(b) Registration Statement which is effective on the date hereof. The Company has advised the Representative of all further information (financial and other) with respect to the Company required to be set forth therein in the Registration Statement and Prospectus. Any reference in this Agreement to the Registration Statement, the Prospectus or any Prospectus Supplement shall be deemed to refer to and include the documents incorporated by reference therein; and any reference in this Agreement to the terms “amend,” “amendment” or “supplement” with respect to the Registration Statement, the Prospectus or any Prospectus Supplement shall be deemed to refer to and include the filing of any document under the Exchange Act after the date of this Agreement, or the issue date of the Prospectus as the case may be, deemed to be incorporated therein by reference. All references in this Agreement to financial statements and schedules and other information which is “contained,” “included,” “described,” “referenced,” “set forth” or “stated” in the Registration Statement, the Prospectus (and all other references of like import) shall be deemed to mean and include all such financial statements and

schedules and other information which is or is deemed to be incorporated by reference in the Registration Statement, or the Prospectus, as the case may be.

The Company will not, without the prior consent of the Representative, prepare, use or refer to, any free writing prospectus.

(g)Issuance of Securities. The Securities are duly authorized and, when issued and paid for in accordance with the applicable Transaction Documents, will be duly and validly issued, fully paid and nonassessable, and free and clear of all Liens imposed by the Company. The Underlying Shares, when issued in accordance with the terms of the Transaction Documents, will be validly issued, fully paid and nonassessable, and free and clear of all Liens imposed by the Company. Other than with respect to the Warrant Shares, the Company has reserved from its duly authorized capital stock, a number of shares of Common Stock for issuance of the Underlying Shares at least equal to the Required Minimum on the date hereof. The holders of the Securities will not be subject to personal liability by reason of being such holders. The Securities are not and will not be subject to the preemptive rights of any holders of any security of the Company or similar contractual rights granted by the Company. All corporate action required to be taken for the authorization, issuance and sale of the Securities has been duly and validly taken. The Securities conform in all material respects to all statements with respect thereto contained in the Registration Statement.

(h)Capitalization. The capitalization of the Company is as set forth in the SEC Reports. The Company has not issued any capital stock since its most recently filed periodic report under the Exchange Act, other than pursuant to the exercise of employee stock options under the Company’s stock option plans and the vesting of restricted stock units under the Company’s equity compensation plans, the issuance of shares of Common Stock to employees participating in the Company’s 401(k) plan as matching contributions pursuant to such plan, the issuance of shares of Common Stock to employees pursuant to the Company’s employee stock purchase plans and pursuant to the conversion and/or exercise of Common Stock Equivalents outstanding as of the date of the most recently filed periodic report under the Exchange Act. No Person has any right of first refusal, preemptive right, right of participation, or any similar right to participate in the transactions contemplated by the Transaction Documents. Other than as disclosed in the Prospectus, and except as a result of (i) the purchase and sale of the Securities, and (ii) the issuance of the shares of Common Stock to employees participating in the Company’s 401(k) plan as matching contributions pursuant to such plan, there are no outstanding options, warrants, scrip rights to subscribe to, calls or commitments of any character whatsoever relating to, or securities, rights or obligations convertible into or exercisable or exchangeable for, or giving any Person any right to subscribe for or

acquire, any shares of Common Stock, or contracts, commitments, understandings or arrangements by which the Company or any Subsidiary is or may become bound to issue additional shares of Common Stock or Common Stock Equivalents. The issuance and sale of the Securities will not obligate the Company to issue shares of Common Stock or other securities to any Person (other than the Underwriters) and will not result in a right of any holder of Company securities to adjust the exercise, conversion, exchange or reset price under any of such securities. All of the outstanding shares of capital stock of the Company are duly authorized, validly issued, fully paid and nonassessable, have been issued in compliance with all federal and state securities laws, and none of such outstanding shares was issued in violation of any preemptive rights or similar rights to subscribe for or purchase securities.

The Company has filed all reports, schedules, forms, statements and other documents required to be filed by the Company under the Securities Act and the Exchange Act, including pursuant to Section 13(a) or 15(d) thereof, for the two years preceding the date hereof (or such shorter period as the Company was required by law or regulation to file such material) (the foregoing materials, including the exhibits thereto and documents incorporated by reference therein, together with the Prospectus and any Prospectus Supplement, being collectively referred to herein as the “SEC Reports”) on a timely basis or has received a valid extension of such time of filing and has filed any such SEC Reports prior to the expiration of any such extension. As of their respective dates, the SEC Reports complied in all material respects with the requirements of the Securities Act and the Exchange Act, as applicable, and none of the SEC Reports, when filed, contained any untrue statement of a material fact or omitted to state a material fact required to be stated therein or necessary in order to make the statements therein, in light of the circumstances under which they were made, not misleading. The financial statements of the Company included in the SEC Reports comply in all material respects with applicable accounting requirements and the rules and regulations of the Commission with respect thereto as in effect at the time of filing. Such financial statements have been prepared in accordance with United States generally accepted accounting principles applied on a consistent basis during the periods involved (“GAAP”), except as may be otherwise specified in such financial statements or the notes thereto and except that unaudited financial statements may not contain all footnotes required by GAAP, and fairly present in all material respects the financial position of the Company and its consolidated Subsidiaries as of and for the dates thereof and the results of operations and cash flows for the periods then ended,

subject, in the case of unaudited statements, to normal, immaterial, year-end audit adjustments. The agreements and documents described in the Registration Statement, the Prospectus, any Prospectus Supplement and the SEC Reports conform to the descriptions thereof contained therein and there are no agreements or other documents required by the Securities Act and the rules and regulations thereunder to be described in the Registration Statement, the Prospectus, any Prospectus Supplement or the SEC Reports or to be filed with the Commission as exhibits to the Registration Statement, that have not been so described or filed.

None of such agreements or instruments has been assigned by the Company, and neither the Company nor, to the best of the Company’s knowledge, any other party is in default thereunder and, to the best of the Company’s knowledge, no event has occurred that, with the lapse of time or the giving of notice, or both, would constitute a default thereunder. To the best of the Company’s knowledge, performance by the Company of the material provisions of such agreements or instruments will not result in a violation of any existing applicable law, rule, regulation, judgment, order or decree of any governmental agency or court, domestic or foreign, having jurisdiction over the Company or any of its assets or businesses, including, without limitation, those relating to environmental laws and regulations.

The Company does not have pending before the Commission any request for confidential treatment of information.

To the knowledge of the Company, no executive officer of the Company or any Subsidiary, is, or is now expected to be, in violation of any material term of any employment contract, confidentiality, disclosure or proprietary

information agreement or non-competition agreement, or any other contract or agreement or any restrictive covenant in favor of any third party, and the continued employment of each such executive officer does not subject the Company or any of its Subsidiaries to any liability with respect to any of the foregoing matters. The Company and its Subsidiaries are in compliance with all U.S. federal, state, local and foreign laws and regulations relating to employment and employment practices, terms and conditions of employment and wages and hours, except where the failure to be in compliance could not, individually or in the aggregate, reasonably be expected to have a Material Adverse Effect.

(n)Regulatory Permits. The Company and the Subsidiaries possess all certificates, authorizations and permits issued by the appropriate federal, state, local or foreign regulatory authorities necessary to conduct their respective businesses as described in the SEC Reports, except where the failure to possess such permits could not reasonably be expected to result in a Material Adverse Effect (each, a “Material Permit”), and neither the Company nor any Subsidiary has received any notice of proceedings relating to the revocation or modification of any Material Permit. The disclosures in the Registration Statement concerning the effects of Federal, State, local and all foreign regulation on the Company’s business as currently contemplated are correct in all material respects.

(o)Title to Assets. The Company and the Subsidiaries have good and marketable title in fee simple to all real property owned by them and good and marketable title in all personal property (excluding the Intellectual Property Rights, which are covered in Section 3.1(p)) owned by them that is material to the business of the Company and the Subsidiaries, in each case free and clear of all Liens, except for (i) Liens as do not materially affect the value of such property and do not materially interfere with the use made and proposed to be made of such property by the Company and the Subsidiaries and (ii) Liens for the payment of federal, state or other taxes, for which appropriate reserves have been made therefor in accordance with GAAP

and, the payment of which is neither delinquent nor subject to penalties. Any real property and facilities held under lease by the Company and the Subsidiaries are held by them under valid, subsisting and enforceable leases with which the Company and the Subsidiaries are in compliance, except where failure to be in compliance could not reasonably be expected to have a Material Adverse Effect.

None of, and neither the Company nor any Subsidiary has received a notice (written or otherwise) that any of, the Intellectual Property Rights has expired, terminated or been abandoned, or is expected to expire or terminate or be abandoned, within two (2) years from the date of this Agreement. Neither the Company nor any Subsidiary has received, since the date of the latest audited financial statements included within the SEC Reports, a written notice of a claim or otherwise has any knowledge that the Intellectual Property Rights violate or infringe upon the rights of any Person, except as could not have or reasonably be expected to have a Material Adverse Effect. To the knowledge of the Company, all such Intellectual Property Rights are enforceable and there is no existing infringement by another Person of any of the Intellectual Property Rights. The Company and its Subsidiaries have taken reasonable security measures to protect the secrecy, confidentiality and value of all of their intellectual properties, except where failure to do so could not, individually or in the aggregate, reasonably be expected to have a Material Adverse Effect.

The Company and the Subsidiaries are insured by insurers of recognized financial responsibility against such losses and risks and in such amounts as are prudent and customary in the businesses in which the Company and the Subsidiaries are engaged, including, but not limited to, directors and officers insurance coverage at least equal to the aggregate Closing Purchase Price. Neither the Company nor any Subsidiary has any reason to believe that it will not be able to renew its existing insurance coverage as and when such coverage expires or to obtain similar coverage from similar insurers as may be necessary to continue its business without a significant increase in cost.

The Company and the Subsidiaries maintain a system of internal accounting controls sufficient to provide reasonable assurance that: (i) transactions are executed in accordance with management’s general or specific authorizations, (ii) transactions are recorded as necessary to permit preparation of financial statements in conformity with GAAP and to maintain asset accountability, (iii) access to assets is permitted only in accordance with management’s general or specific authorization, and (iv) the recorded accountability for assets is compared with the existing assets at reasonable intervals and appropriate action is taken with respect to any differences. The Company and the Subsidiaries have established disclosure controls and procedures (as defined in Exchange Act Rules 13a-15(e) and 15d-15(e)) for the Company and the Subsidiaries and designed such disclosure controls and procedures to ensure that information required to be disclosed by the Company in the reports it files or submits under the Exchange Act is recorded, processed, summarized and reported, within the time periods specified in the Commission’s rules and forms. The Company’s certifying officers have evaluated the effectiveness of the disclosure controls and procedures of the Company and the Subsidiaries as of the end of the period covered by the most recently filed periodic report under the Exchange Act (such date, the “Evaluation Date”). The Company presented in its most recently filed periodic report under the Exchange Act the conclusions of its certifying officers about the effectiveness of the disclosure controls and procedures based on their evaluations as of the Evaluation Date. As disclosed in the SEC Reports, the Company’s certifying officers concluded that a material weakness related to the calculation of stock compensation expense existed as of the Evaluation Date. Except for work undertaken to remediate such weakness, since the Evaluation Date, there have been no changes in the internal control over financial reporting (as such term is defined in the Exchange Act) of the Company and its Subsidiaries that have materially affected, or is reasonably likely to materially affect, the internal control over financial reporting of the Company and its Subsidiaries.

(t)Certain Fees. Except as set forth in the Prospectus or any Prospectus Supplement, no brokerage or finder’s fees or commissions are or will be payable by

the Company, any Subsidiary or Affiliate of the Company to any broker, financial advisor or consultant, finder, placement agent, investment banker, bank or other Person with respect to the transactions contemplated by the Transaction Documents. To the Company’s knowledge, there are no other arrangements, agreements or understandings of the Company or, to the Company’s knowledge, any of its stockholders that may affect the Underwriters’ compensation, as determined by FINRA. The Company has not made any direct or indirect payments (in cash, securities or otherwise) to: (i) any person, as a finder’s fee, consulting fee or otherwise, in consideration of such person raising capital for the Company or introducing to the Company persons who raised or provided capital to the Company; (ii) any FINRA member; or (iii) any person or entity that has any direct or indirect affiliation or association with any FINRA member, within the twelve months prior to the Execution Date.

Except as disclosed in the SEC Reports, the Company has not, in the 12 months preceding the date hereof, received notice from any Trading Market on which the Common Stock is or has been listed or quoted to the effect that the Company is not in compliance with the listing or maintenance requirements of such Trading Market.

(x)Application of Takeover Protections. The Company and the Board of Directors have taken all necessary action, if any, in order to render inapplicable any control share acquisition, business combination, poison pill (including any distribution under a rights agreement) or other similar anti‑takeover provision under the Company’s certificate of incorporation (or similar charter documents) or the laws of its state of incorporation that is or could become applicable as a result of the Underwriters and the Company fulfilling their obligations or exercising their rights under the Transaction Documents.

(y)Disclosure; 10b-5. The Registration Statement (and any further documents to be filed with the Commission in connection with the Offering) contains all exhibits and schedules as required by the Securities Act. Each of the Registration Statement and any post-effective amendment thereto, if any, at the time it became effective, complied in all material respects with the Securities Act and the Exchange Act and the applicable rules and regulations under the Securities Act and did not and, as amended or supplemented, if applicable, will not, contain any untrue statement of a material fact or omit to state a material fact required to be stated therein or necessary to make the statements therein not misleading. The Prospectus and any Prospectus Supplement, each as of its respective date, comply in all material respects with the Securities Act and the Exchange Act and the applicable rules and regulations. Each of the Prospectus and any Prospectus Supplement, as amended or supplemented, did not and will not contain as of the date thereof any untrue statement of a material fact or omit to state a material fact necessary in order to make the statements therein, in light of the circumstances under which they were made, not misleading. Any further SEC Reports, to be filed and incorporated by reference in the Prospectus or any Prospectus Supplement, when such documents are filed with the Commission, will conform in all material respects to the requirements of the Exchange Act and the applicable rules and regulations, as applicable, and will not contain any untrue statement of a material fact or omit to state a material fact necessary to make the statements therein, in light of the circumstances under which they were made not misleading.

There are no contracts or other documents required to be described in the Prospectus or any Prospectus Supplement, or to be filed as exhibits or schedules to the Registration Statement, which have not been described or filed as required.

(z)No Integrated Offering. Neither the Company, nor any of its Affiliates, nor any Person acting on its or their behalf has, directly or indirectly, made any offers or sales of any security or solicited any offers to buy any security, under circumstances that would cause this offering of the Securities to be integrated with

prior offerings by the Company for purposes of any applicable shareholder approval provisions of any Trading Market on which any of the securities of the Company are listed or designated.

(aa)Solvency. Based on the consolidated financial condition of the Company as of the Closing Date, after giving effect to the receipt by the Company of the proceeds from the sale of the Securities hereunder, (i) the fair saleable value of the Company’s assets exceeds the amount that will be required to be paid on or in respect of the Company’s existing debts and other liabilities (including known contingent liabilities) as they mature, (ii) the Company’s assets do not constitute unreasonably small capital to carry on its business as now conducted and as proposed to be conducted including its capital needs taking into account the particular capital requirements of the business conducted by the Company, consolidated and projected capital requirements and capital availability thereof, and (iii) the current cash flow of the Company, together with the proceeds the Company would receive, were it to liquidate all of its assets, after taking into account all anticipated uses of the cash, would be sufficient to pay all amounts on or in respect of its liabilities when such amounts are required to be paid. The Company does not intend to incur debts beyond its ability to pay such debts as they mature (taking into account the timing and amounts of cash to be payable on or in respect of its debt). The Company has no knowledge of any facts or circumstances which lead it to believe that it will file for reorganization or liquidation under the bankruptcy or reorganization laws of any jurisdiction within six months from the Closing Date.

There are no unpaid taxes in any material amount claimed to be due by the taxing authority of any jurisdiction, and the officers of the Company or of any Subsidiary know of no basis for any such claim. The provisions for taxes payable, if any, shown on the financial statements filed with or as part of the Registration Statement are sufficient for all accrued and unpaid taxes, whether or not disputed, and for all periods to and including the dates of such consolidated financial statements. The term “taxes” means all federal, state, local, foreign, and other net income, gross income, gross receipts, sales, use, ad valorem, transfer, franchise, profits, license, lease, service, service use,

ARTICLE V.

DEFAULT BY UNDERWRITERS

If on the Closing Date or any Option Closing Date, if any, any Underwriter shall fail to purchase and pay for the portion of the Closing Securities or Option Securities, as the case may be, which such Underwriter has agreed to purchase and pay for on such date (otherwise than by reason of any default on the part of the Company), the Representative, or if the Representative is the defaulting Underwriter, the non-defaulting Underwriters, shall use their reasonable efforts to procure within 36 hours thereafter one or more of the other Underwriters, or any others, to purchase from the Company such amounts as may be agreed upon and upon the terms set forth herein, the Closing Securities or Option Securities, as the case may be, which the defaulting Underwriter or Underwriters failed to purchase. If during such 36 hours the Representative shall not have procured such other Underwriters, or any others, to purchase the Closing Securities or Option Securities, as the case may be, agreed to be purchased by the defaulting Underwriter or Underwriters, then (a) if the aggregate number of Closing Securities or Option Securities, as the case may be, with respect to which such default shall occur does not exceed 10% of the Closing Securities or Option Securities, as the case may be, covered hereby, the other Underwriters shall be obligated, severally, in proportion to the respective numbers of Closing Securities or Option Securities, as the case may be, which they are obligated to purchase hereunder, to purchase the Closing Securities or Option Securities, as the case may be, which such defaulting Underwriter or Underwriters failed to purchase, or (b) if the aggregate number of Closing Securities or Option Securities, as the case may be, with respect to which such default shall occur exceeds 10% of the Closing Securities or Option Securities, as the case may be, covered hereby, the Company or the Representative will have the right to terminate this Agreement without liability on the part of the non-defaulting Underwriters or of the Company except to the extent provided in Article VI hereof. In the event of a default by any Underwriter or Underwriters, as set forth in this Article V, the applicable Closing Date may be postponed for such period, not exceeding seven days, as the Representative, or if the Representative is the defaulting Underwriter, the non-defaulting Underwriters, may determine in order that the required changes in the Prospectus or in any other documents or arrangements may be effected. The term “Underwriter” includes any person substituted for a defaulting Underwriter. Any action taken under this Section shall not relieve any defaulting Underwriter from liability in respect of any default of such Underwriter under this Agreement.

ARTICLE VI.

INDEMNIFICATION

6.1Indemnification of the Underwriters. Subject to the conditions set forth below, the Company agrees to indemnify and hold harmless the Underwriters, and each dealer selected by each Underwriter that participates in the offer and sale of the Securities (each a “Selected Dealer”) and each of their respective directors, officers and employees and each Person, if any, who controls such Underwriter or any Selected Dealer (“Controlling Person”) within the meaning of Section 15 of the Securities Act or Section 20 of the Exchange Act, against any and all loss, liability, claim, damage and expense whatsoever (including but not limited to any and all legal or other expenses reasonably incurred in investigating, preparing or defending against any litigation, commenced or

threatened, or any claim whatsoever, whether arising out of any action between such Underwriter and the Company or between such Underwriter and any third party or otherwise) to which they or any of them may become subject under the Securities Act, the Exchange Act or any other statute or at common law or otherwise or under the laws of foreign countries, arising out of or based upon any untrue statement or alleged untrue statement of a material fact contained in (i) any Preliminary Prospectus, if any, the Registration Statement or the Prospectus (as from time to time each may be amended and supplemented); (ii) any materials or information provided to investors by, or with the approval of, the Company in connection with the marketing of the offering of the Securities, including any “road show” or investor presentations made to investors by the Company (whether in person or electronically); or (iii) any application or other document or written communication (in this Article VI, collectively called “application”) executed by the Company or based upon written information furnished by the Company in any jurisdiction in order to qualify the Securities under the securities laws thereof or filed with the Commission, any state securities commission or agency, Trading Market or any securities exchange; or the omission or alleged omission therefrom of a material fact required to be stated therein or necessary to make the statements therein, in light of the circumstances under which they were made, not misleading, unless such statement or omission was made in reliance upon and in conformity with written information furnished to the Company with respect to the applicable Underwriter by or on behalf of such Underwriter expressly for use in any Preliminary Prospectus, if any, the Registration Statement or Prospectus, or any amendment or supplement thereto, or in any application, as the case may be. With respect to any untrue statement or omission or alleged untrue statement or omission made in the Preliminary Prospectus, if any, the indemnity agreement contained in this Section 6.1 shall not inure to the benefit of an Underwriter to the extent that any loss, liability, claim, damage or expense of such Underwriter results from the fact that a copy of the Prospectus was not given or sent to the Person asserting any such loss, liability, claim or damage at or prior to the written confirmation of sale of the Securities to such Person as required by the Securities Act and the rules and regulations thereunder, and if the untrue statement or omission has been corrected in the Prospectus, unless such failure to deliver the Prospectus was a result of non-compliance by the Company with its obligations under this Agreement. The Company agrees promptly to notify each Underwriter of the commencement of any litigation or proceedings against the Company or any of its officers, directors or Controlling Persons in connection with the issue and sale of the Public Securities or in connection with the Registration Statement or Prospectus.

6.2Procedure. If any action is brought against an Underwriter, a Selected Dealer or a Controlling Person in respect of which indemnity may be sought against the Company pursuant to Section 6.1, such Underwriter, such Selected Dealer or Controlling Person, as the case may be, shall promptly notify the Company in writing of the institution of such action and the Company shall assume the defense of such action, including the employment and fees of counsel (subject to the reasonable approval of such Underwriter or such Selected Dealer, as the case may be) and payment of actual expenses. Such Underwriter, such Selected Dealer or Controlling Person shall have the right to employ its or their own counsel in any such case, but the fees and expenses of such counsel shall be at the expense of such Underwriter, such Selected Dealer or Controlling Person unless (i) the employment of such counsel at the expense of the Company shall have been authorized in writing by the Company in connection with the defense of such action, or (ii) the Company shall not have employed counsel to have charge of the defense of such action, or (iii) such indemnified party or parties shall have reasonably concluded that there may be defenses available to it or them which

are different from or additional to those available to the Company (in which case the Company shall not have the right to direct the defense of such action on behalf of the indemnified party or parties), in any of which events the reasonable fees and expenses of not more than one additional firm of attorneys selected by such Underwriter (in addition to local counsel), Selected Dealer and/or Controlling Person shall be borne by the Company. Notwithstanding anything to the contrary contained herein, if any Underwriter, Selected Dealer or Controlling Person shall assume the defense of such action as provided above, the Company shall have the right to approve the terms of any settlement of such action which approval shall not be unreasonably withheld.

6.3Indemnification of the Company. Each Underwriter severally and not jointly agrees to indemnify and hold harmless the Company, its directors, officers and employees and agents who control the Company within the meaning of Section 15 of the Securities Act or Section 20 of the Exchange Act against any and all loss, liability, claim, damage and expense described in the foregoing indemnity from the Company to such Underwriter, as incurred, but only with respect to untrue statements or omissions, or alleged untrue statements or omissions made in any Preliminary Prospectus, if any, the Registration Statement or Prospectus or any amendment or supplement thereto or in any application, in reliance upon, and in strict conformity with, written information furnished to the Company with respect to such Underwriter by or on behalf of such Underwriter expressly for use in such Preliminary Prospectus, if any, the Registration Statement or Prospectus or any amendment or supplement thereto or in any such application. In case any action shall be brought against the Company or any other Person so indemnified based on any Preliminary Prospectus, if any, the Registration Statement or Prospectus or any amendment or supplement thereto or any application, and in respect of which indemnity may be sought against such Underwriter, such Underwriter shall have the rights and duties given to the Company, and the Company and each other Person so indemnified shall have the rights and duties given to such Underwriter by the provisions of this Article VI. Notwithstanding the provisions of this Section 6.3, no Underwriter shall be required to indemnify the Company for any amount in excess of the underwriting discounts and commissions applicable to the Securities purchased by such Underwriter. The Underwriters' obligations in this Section 6.3 to indemnify the Company are several in proportion to their respective underwriting obligations and not joint.

6.4Contribution.

(a)Contribution Rights. In order to provide for just and equitable contribution under the Securities Act in any case in which (i) any Person entitled to indemnification under this Article VI makes a claim for indemnification pursuant hereto but it is judicially determined (by the entry of a final judgment or decree by a court of competent jurisdiction and the expiration of time to appeal or the denial of the last right of appeal) that such indemnification may not be enforced in such case notwithstanding the fact that this Article VI provides for indemnification in such case, or (ii) contribution under the Securities Act, the Exchange Act or otherwise may be required on the part of any such Person in circumstances for which indemnification is provided under this Article VI, then, and in each such case, the Company and each Underwriter, severally and not jointly, shall contribute to the aggregate losses, liabilities, claims, damages and expenses of the nature contemplated by said indemnity agreement incurred by the Company and such Underwriter, as incurred,

in such proportions that such Underwriter is responsible for that portion represented by the percentage that the underwriting discount appearing on the cover page of the Prospectus bears to the initial offering price appearing thereon and the Company is responsible for the balance; provided, that, no Person guilty of a fraudulent misrepresentation (within the meaning of Section 11(f) of the Securities Act) shall be entitled to contribution from any Person who was not guilty of such fraudulent misrepresentation. For purposes of this Section, each director, officer and employee of such Underwriter or the Company, as applicable, and each Person, if any, who controls such Underwriter or the Company, as applicable, within the meaning of Section 15 of the Securities Act shall have the same rights to contribution as such Underwriter or the Company, as applicable. Notwithstanding the provisions of this Section 6.4, no Underwriter shall be required to contribute any amount in excess of the underwriting discounts and commissions applicable to the Securities purchased by such Underwriter. The Underwriters' obligations in this Section 6.4 to contribute are several in proportion to their respective underwriting obligations and not joint.

(b)Contribution Procedure. Within fifteen days after receipt by any party to this Agreement (or its representative) of notice of the commencement of any action, suit or proceeding, such party will, if a claim for contribution in respect thereof is to be made against another party (“contributing party”), notify the contributing party of the commencement thereof, but the failure to so notify the contributing party will not relieve it from any liability which it may have to any other party other than for contribution hereunder. In case any such action, suit or proceeding is brought against any party, and such party notifies a contributing party or its representative of the commencement thereof within the aforesaid fifteen days, the contributing party will be entitled to participate therein with the notifying party and any other contributing party similarly notified. Any such contributing party shall not be liable to any party seeking contribution on account of any settlement of any claim, action or proceeding effected by such party seeking contribution without the written consent of such contributing party. The contribution provisions contained in this Section 6.4 are intended to supersede, to the extent permitted by law, any right to contribution under the Securities Act, the Exchange Act or otherwise available.

ARTICLE VII.

MISCELLANEOUS

Each party hereby irrevocably submits to the exclusive jurisdiction of the state and federal courts sitting in the City of New York, Borough of Manhattan for the adjudication of any dispute hereunder or in connection herewith or with any transaction contemplated hereby or discussed herein (including with respect to the enforcement of any of the Transaction Documents), and hereby irrevocably waives, and agrees not to assert in any action, suit or proceeding, any claim that it is not personally subject to the jurisdiction of any such court, that such suit, action or proceeding is improper or is an inconvenient venue for such proceeding. Each party hereby irrevocably waives personal service of process and consents to process being served in any such suit, action or proceeding by mailing a copy thereof via registered or certified mail or overnight delivery (with evidence of delivery) to such party at the address in effect for notices to it under this Agreement and agrees that such service shall constitute good and sufficient service of process and notice thereof. Nothing contained herein shall be deemed to limit in any way any right to serve process in any other manner permitted by law. If either party shall commence an action or proceeding to enforce any provisions of the Transaction Documents, then, in addition to the obligations of the Company under Article VI, the prevailing party in such action, suit or proceeding shall be reimbursed by the other party for its reasonable attorneys’ fees and other

In addition, a beneficial owner of Preferred Stock has the right, upon written notice by such beneficial owner to the Corporation, to request the exchange of some or all of such beneficial owner’s interest in Preferred Stock represented by one or more global Preferred Stock certificates deposited with Cede & Co. (or its successor) for a physical Preferred Stock certificate (a “Preferred Stock Certificate Request Notice” and the date of delivery of such Preferred Stock Certificate Request Notice by a beneficial owner, the “Preferred Stock Certificate Request Notice Date” and the deemed surrender upon delivery by the beneficial owner of a number of global shares of Preferred Stock for the same number of shares of Preferred Stock represented by a physical stock certificate, a “Preferred Stock Exchange”, and such physical certificate(s), a “Preferred Stock Certificate”). Upon delivery of a Preferred Stock Certificate Request Notice, the Corporation shall promptly effect the Preferred Stock Exchange and shall promptly issue and deliver to the beneficial owner a physical Preferred Stock Certificate for such number of shares of Preferred Stock represented by its interest in such global certificates in the name of the beneficial owner. Such Preferred Stock Certificate shall be dated the original issue date and shall be executed by an authorized signatory of the Corporation. In connection with a Preferred Stock Exchange, the Corporation agrees to deliver the Preferred Stock Certificate to the Holder within two (2) Business Days of the delivery of a properly completed and executed Preferred Stock Certificate Request Notice pursuant to the delivery instructions in the Preferred Stock Certificate Request Notice. The Corporation covenants and agrees that, upon the date of delivery of the properly completed and executed Preferred Stock Certificate Request Notice, the Holder shall be deemed to be the holder of the Preferred Stock Certificate and further, for purposes of Regulation SHO, a Holder whose interest in this Preferred Stock is a beneficial interest in certificate(s) representing this Preferred Stock held in book-entry form through DTC shall be deemed to have converted its interest in this Preferred Stock upon instructing its broker that is a DTC participant to convert its interest in this Preferred Stock, and, notwithstanding anything to the contrary set forth herein, the Preferred Stock Certificate shall be deemed for all purposes to represent all of the terms and conditions of the Preferred Stock evidenced by such global Preferred Stock certificates and the terms hereof.

Section 3. Dividends. Except for stock dividends or distributions for which adjustments are to be made pursuant to Section 7, Holders shall be entitled to receive, and the Corporation shall pay, dividends on shares of Preferred Stock equal (on an as-if-converted-to-Common-Stock basis, disregarding for such purpose any conversion limitations hereunder) to and in the same form as dividends actually paid on shares of the Common Stock when, as and if such dividends are paid on shares of the Common Stock. No other dividends shall be paid on shares of Preferred Stock. The Corporation shall not pay any dividends on the Common Stock unless the Corporation simultaneously complies with this provision.

Section 4. Voting Rights. Except as otherwise provided herein or as otherwise required by law, the Preferred Stock shall have no voting rights. However, as long as any shares of Preferred Stock are outstanding, the Corporation shall not, without the affirmative vote of the Holders of a majority of the then outstanding shares of the Preferred Stock, (a) alter or change adversely the powers, preferences or rights given to the Preferred Stock or alter or amend this Certificate of Designation, (b) amend its certificate of incorporation or other charter documents in any manner that adversely affects any rights of the Holders, (c) increase the number of authorized shares of Preferred Stock, or (d) enter into any agreement with respect to any of the foregoing.

Section 5. Liquidation. Upon any liquidation, dissolution or winding-up of the Corporation, whether voluntary or involuntary (a “Liquidation”), the Holders shall be entitled to receive out of the assets, whether capital or surplus, of the Corporation the same amount that a holder of Common Stock would receive if the Preferred Stock were fully converted (disregarding for such purposes any conversion limitations hereunder) to Common Stock which amounts shall be paid pari passu with all holders of Common Stock. The Corporation shall mail written notice of any such Liquidation, not less than 45 days prior to the payment date stated therein, to each Holder.

Section 6. Conversion.

a)Conversions at Option of Holder. Each share of Preferred Stock shall be convertible, at any time and from time to time from and after the Original Issue Date at the option of the Holder thereof, into that number of shares of Common Stock (subject to the limitations set forth in Section 6(d)) determined by dividing the Stated Value of such share of Preferred Stock by the Conversion Price. Holders shall effect conversions by providing the Corporation with the form of conversion notice attached hereto as Annex A (a “Notice of Conversion”). Each Notice of Conversion shall specify the number of shares of Preferred Stock to be converted, the number of shares of Preferred Stock owned prior to the conversion at issue, the number of shares of Preferred Stock owned subsequent to the conversion at issue and the date on which such conversion is to be effected, which date may not be prior to the date the applicable Holder delivers by facsimile or e-mail such Notice of Conversion to the Corporation (such date, the “Conversion Date”). If no Conversion Date is specified in a Notice of Conversion, the Conversion Date shall be the date that such Notice of Conversion to the Corporation is deemed delivered hereunder. No ink-original Notice of Conversion shall be required, nor shall any medallion guarantee (or other type of guarantee or notarization) of any Notice of Conversion form be required. The calculations and entries set forth in the Notice of Conversion shall control in the absence of manifest or mathematical

error. To effect conversions of shares of Preferred Stock, a Holder shall not be required to surrender the certificate(s) representing the shares of Preferred Stock to the Corporation unless all of the shares of Preferred Stock represented thereby are so converted, in which case such Holder shall deliver the certificate representing such shares of Preferred Stock promptly following the Conversion Date at issue. Shares of Preferred Stock converted into Common Stock or redeemed in accordance with the terms hereof shall be canceled and shall not be reissued. Notwithstanding the foregoing in this Section 6(a), a holder whose interest in the Preferred Stock is a beneficial interest in certificate(s) representing the Preferred Stock held in book-entry form through DTC (or another established clearing corporation performing similar functions), shall effect conversions made pursuant to this Section 6(a) by delivering to DTC (or such other clearing corporation, as applicable) the appropriate instruction form for conversion, complying with the procedures to effect conversions that are required by DTC (or such other clearing corporation, as applicable), subject to a Holder’s right to elect to receive Preferred Stock in certificated form pursuant to Section 2, in which case this sentence shall not apply, and, provided, however, as between the Corporation and a beneficial owner of Preferred Stock held in book-entry form through DTC (or another established clearing corporation performing similar functions) shall have all of the rights and remedies of a “Holder” hereunder.

b)Conversion Price. The conversion price for the Preferred Stock shall equal $_____, subject to adjustment as provided for herein (the “Conversion Price”).


c)	Mechanics of Conversion

i.Delivery of Conversion Shares Upon Conversion. Not later than the earlier of (i) two (2) Trading Days and (ii) the number of Trading Days comprising the Standard Settlement Period (as defined below) after each Conversion Date (the “Share Delivery Date”), the Corporation shall deliver, or cause to be delivered, to the converting Holder (A) the number of Conversion Shares being acquired upon the conversion of the Preferred Stock, which Conversion Shares shall be free of restrictive legends and trading restrictions, and (B) a bank check in the amount of accrued and unpaid dividends, if any. The Corporation shall use its best efforts to deliver the Conversion Shares required to be delivered by the Corporation under this Section 6 electronically through the Depository Trust Company or another established clearing corporation performing similar functions. As used herein, “Standard Settlement Period” means the standard settlement period, expressed in a number of Trading Days, on the Corporation’s primary Trading Market with respect to the Common Stock as in effect on the date of delivery of the Notice of Conversion. Notwithstanding the foregoing, with respect to any Notice(s) of Conversion delivered by 12:00 p.m. (New York City time) on the Original Issue Date, the Corporation agrees to deliver the Conversion Shares subject to such notice(s) by 4:00 p.m. (New York City time) on the Original Issue Date, and the Original Issue Date being deemed the "Share Delivery Date" with respect to any Notice(s) of Conversion.

ii.Failure to Deliver Conversion Shares. If, in the case of any Notice of Conversion, such Conversion Shares are not delivered to or as directed by the applicable Holder by the Share Delivery Date, the Holder shall be entitled to elect by written notice to the Corporation at any time on or before its receipt of such Conversion Shares, to rescind such Conversion, in which event the Corporation shall promptly return to the Holder any original Preferred Stock certificate delivered to the Corporation and the Holder shall promptly return to the Corporation the Conversion Shares issued to such Holder pursuant to the rescinded Notice of Conversion.

iii.Obligation Absolute; Partial Liquidated Damages. The Corporation’s obligation to issue and deliver the Conversion Shares upon conversion of Preferred Stock in accordance with the terms hereof are absolute and unconditional, irrespective of any action or inaction by a Holder to enforce the same, any waiver or consent with respect to any provision hereof, the recovery of any judgment against any Person or any action to enforce the same, or any setoff, counterclaim, recoupment, limitation or termination, or any breach or alleged breach by such Holder or any other Person of any obligation to the Corporation or any violation or alleged violation of law by such Holder or any other person, and irrespective of any other circumstance which might otherwise limit such obligation of the Corporation to such Holder in connection with the issuance of such Conversion Shares; provided, however, that such delivery shall not operate as a waiver by the Corporation of any such action that the Corporation may have against such Holder. In the event a Holder shall elect to convert any or all of the Stated Value of its Preferred Stock, the Corporation may not refuse conversion based on any claim that such Holder or any one associated or affiliated with such Holder has been engaged in any violation of law, agreement or for any other reason, unless an injunction from a court, on notice to Holder, restraining and/or enjoining conversion of all or part of the Preferred Stock of such Holder shall have been sought and obtained, and the Corporation posts a surety bond for the benefit of such Holder in the amount of 110% of the Stated Value of Preferred Stock which is subject to the injunction, which bond shall remain in effect until the completion of arbitration/litigation of the underlying dispute and the proceeds of which shall be payable to such Holder to the extent it obtains judgment. In the absence of such injunction, the Corporation shall issue Conversion Shares and, if applicable, cash, upon a properly noticed conversion. If the Corporation fails to deliver to a Holder such Conversion Shares pursuant to Section 6(c)(i) by the Share Delivery Date applicable to such conversion, the Corporation shall pay to such Holder, in cash, as liquidated damages and not as a penalty, for each $5,000 of Stated Value of Preferred Stock being converted, $25 per Trading Day (increasing to $50 per Trading Day on the third Trading Day and increasing to $100 per Trading Day on the sixth Trading Day after such damages begin to accrue) for each Trading Day after the Share Delivery Date until such Conversion Shares are delivered or Holder rescinds such conversion. Nothing herein shall limit a Holder’s right to pursue actual damages for the Corporation’s failure to deliver Conversion Shares within the period specified herein and such Holder shall

have the right to pursue all remedies available to it hereunder, at law or in equity including, without limitation, a decree of specific performance and/or injunctive relief. The exercise of any such rights shall not prohibit a Holder from seeking to enforce damages pursuant to any other Section hereof or under applicable law.

iv.Compensation for Buy-In on Failure to Timely Deliver Conversion Shares Upon Conversion. In addition to any other rights available to the Holder, if the Corporation fails for any reason to deliver to a Holder the applicable Conversion Shares by the Share Delivery Date pursuant to Section 6(c)(i), and if after such Share Delivery Date such Holder is required by its brokerage firm to purchase (in an open market transaction or otherwise), or the Holder’s brokerage firm otherwise purchases, shares of Common Stock to deliver in satisfaction of a sale by such Holder of the Conversion Shares which such Holder was entitled to receive upon the conversion relating to such Share Delivery Date (a “Buy-In”), then the Corporation shall (A) pay in cash to such Holder (in addition to any other remedies available to or elected by such Holder) the amount, if any, by which (x) such Holder’s total purchase price (including any brokerage commissions) for the Common Stock so purchased exceeds (y) the product of (1) the aggregate number of shares of Common Stock that such Holder was entitled to receive from the conversion at issue multiplied by (2) the actual sale price at which the sell order giving rise to such purchase obligation was executed (including any brokerage commissions) and (B) at the option of such Holder, either reissue (if surrendered) the shares of Preferred Stock equal to the number of shares of Preferred Stock submitted for conversion (in which case, such conversion shall be deemed rescinded) or deliver to such Holder the number of shares of Common Stock that would have been issued if the Corporation had timely complied with its delivery requirements under Section 6(c)(i). For example, if a Holder purchases shares of Common Stock having a total purchase price of $11,000 to cover a Buy-In with respect to an attempted conversion of shares of Preferred Stock with respect to which the actual sale price of the Conversion Shares (including any brokerage commissions) giving rise to such purchase obligation was a total of $10,000 under clause (A) of the immediately preceding sentence, the Corporation shall be required to pay such Holder $1,000. The Holder shall provide the Corporation written notice indicating the amounts payable to such Holder in respect of the Buy-In and, upon request of the Corporation, evidence of the amount of such loss. Nothing herein shall limit a Holder’s right to pursue any other remedies available to it hereunder, at law or in equity including, without limitation, a decree of specific performance and/or injunctive relief with respect to the Corporation’s failure to timely deliver the Conversion Shares upon conversion of the shares of Preferred Stock as required pursuant to the terms hereof.

v.Reservation of Shares Issuable Upon Conversion. The Corporation covenants that it will at all times reserve and keep available out of its authorized and unissued shares of Common Stock for the sole purpose of issuance upon conversion of the Preferred Stock as herein provided, free from preemptive rights or any other actual contingent purchase rights of Persons other than the Holder (and the other

holders of the Preferred Stock), not less than such aggregate number of shares of the Common Stock as shall be issuable (taking into account the adjustments and restrictions of Section 7) upon the conversion of the then outstanding shares of Preferred Stock. The Corporation covenants that all shares of Common Stock that shall be so issuable shall, upon issue, be duly authorized, validly issued, fully paid and nonassessable.

vi.Fractional Shares. No fractional shares or scrip representing fractional shares shall be issued upon the conversion of the Preferred Stock. As to any fraction of a share which the Holder would otherwise be entitled to purchase upon such conversion, the Corporation shall round up to the next whole share.

vii.Transfer Taxes and Expenses. The issuance of Conversion Shares on conversion of this Preferred Stock shall be made without charge to any Holder for any documentary stamp or similar taxes that may be payable in respect of the issue or delivery of such Conversion Shares, provided that the Corporation shall not be required to pay any tax that may be payable in respect of any transfer involved in the issuance and delivery of any such Conversion Shares upon conversion in a name other than that of the Holders of such shares of Preferred Stock and the Corporation shall not be required to issue or deliver such Conversion Shares unless or until the Person or Persons requesting the issuance thereof shall have paid to the Corporation the amount of such tax or shall have established to the satisfaction of the Corporation that such tax has been paid. The Corporation shall pay all Transfer Agent fees required for same-day processing of any Notice of Conversion and all fees to the Depository Trust Company (or another established clearing corporation performing similar functions) required for same-day electronic delivery of the Conversion Shares.

d)Beneficial Ownership Limitation. The Corporation shall not effect any conversion of the Preferred Stock, and a Holder shall not have the right to convert any portion of the Preferred Stock, to the extent that, after giving effect to the conversion set forth on the applicable Notice of Conversion, such Holder (together with such Holder’s Affiliates, and any Persons acting as a group together with such Holder or any of such Holder’s Affiliates (such Persons, “Attribution Parties”)) would beneficially own in excess of the Beneficial Ownership Limitation (as defined below). For purposes of the foregoing sentence, the number of shares of Common Stock beneficially owned by such Holder and its Affiliates and Attribution Parties shall include the number of shares of Common Stock issuable upon conversion of the Preferred Stock with respect to which such determination is being made, but shall exclude the number of shares of Common Stock which are issuable upon (i) conversion of the remaining, unconverted Stated Value of Preferred Stock beneficially owned by such Holder or any of its Affiliates or Attribution Parties and (ii) exercise or conversion of the unexercised or unconverted portion of any other securities of the Corporation subject to a limitation on conversion or exercise analogous to the limitation contained herein (including, without limitation, the Preferred Stock) beneficially owned by such Holder or any of its Affiliates or Attribution Parties. Except as set forth in the preceding

sentence, for purposes of this Section 6(d), beneficial ownership shall be calculated in accordance with Section 13(d) of the Exchange Act and the rules and regulations promulgated thereunder. Subject to a Holder's right to rely on the number of outstanding shares of Common Stock as set forth below, the Corporation makes no representation to the Holder that its calculations are in compliance with Section 13(d) of the Exchange Act and that the Holder is solely responsible for any schedules required to be filed in accordance therewith. To the extent that the limitation contained in this Section 6(d) applies, the determination of whether the Preferred Stock is convertible (in relation to other securities owned by such Holder together with any Affiliates and Attribution Parties) and of how many shares of Preferred Stock are convertible shall be in the sole discretion of such Holder, and the submission of a Notice of Conversion shall be deemed to be such Holder’s determination of whether the shares of Preferred Stock may be converted (in relation to other securities owned by such Holder together with any Affiliates and Attribution Parties) and how many shares of the Preferred Stock are convertible, in each case subject to the Beneficial Ownership Limitation. To ensure compliance with this restriction, each Holder will be deemed to represent to the Corporation each time it delivers a Notice of Conversion that such Notice of Conversion has not violated the restrictions set forth in this paragraph and the Corporation shall have no obligation to verify or confirm the accuracy of such determination. In addition, a determination as to any group status as contemplated above shall be determined in accordance with Section 13(d) of the Exchange Act and the rules and regulations promulgated thereunder. For purposes of this Section 6(d), in determining the number of outstanding shares of Common Stock, a Holder may rely on the number of outstanding shares of Common Stock as stated in the most recent of the following: (i) the Corporation’s most recent periodic or annual report filed with the Commission, as the case may be, (ii) a more recent public announcement by the Corporation or (iii) a more recent written notice by the Corporation or the Transfer Agent setting forth the number of shares of Common Stock outstanding. Upon the written or oral request (which may be via email) of a Holder, the Corporation shall within one Trading Day confirm orally and in writing to such Holder the number of shares of Common Stock then outstanding. In any case, the number of outstanding shares of Common Stock shall be determined after giving effect to the conversion or exercise of securities of the Corporation, including the Preferred Stock, by such Holder or its Affiliates or Attribution Parties since the date as of which such number of outstanding shares of Common Stock was reported. The “Beneficial Ownership Limitation” shall be 4.99% (or, upon election by a Holder prior to the issuance of any shares of Preferred Stock, 9.99%) of the number of shares of the Common Stock outstanding immediately after giving effect to the issuance of shares of Common Stock issuable upon conversion of Preferred Stock held by the applicable Holder. A Holder, upon notice to the Corporation, may increase or decrease the Beneficial Ownership Limitation provisions of this Section 6(d) applicable to its Preferred Stock provided that the Beneficial Ownership Limitation in no event exceeds 9.99% of the number of shares of the Common Stock outstanding immediately after giving effect to the issuance of shares of Common Stock upon conversion of this Preferred Stock held by the Holder and the provisions of this Section 6(d) shall continue to apply. Any such increase in the Beneficial Ownership Limitation will not be effective until the 61^st day after such notice is delivered to the Corporation and shall only apply to such Holder and no other Holder. The provisions of this paragraph shall be construed and implemented in a manner

otherwise than in strict conformity with the terms of this Section 6(d) to correct this paragraph (or any portion hereof) which may be defective or inconsistent with the intended Beneficial Ownership Limitation contained herein or to make changes or supplements necessary or desirable to properly give effect to such limitation. The limitations contained in this paragraph shall apply to a successor holder of Preferred Stock.

e)Forced Conversion. Notwithstanding anything herein to the contrary, if after the Original Issue Date, the VWAP during any 30 consecutive Trading Day period, which thirty (30) consecutive Trading Day period shall have commenced only after the Original Issue Date (the “Threshold Period”), exceeds $______¹ (subject to adjustment for forward and reverse stock splits, recapitalizations, stock dividends and the like after the Original Issue Date) and (ii) the daily dollar trading volume for such Threshold Period exceeds $175,000 per Trading Day, the Corporation may, within one (1) Trading Day after the end of any such Threshold Period, deliver a written notice to all Holders (a “Forced Conversion Notice” and the date such notice is delivered to all Holders, the “Forced Conversion Notice Date”) to cause each Holder to convert all or part of such Holder’s Preferred Stock (as specified in such Forced Conversion Notice) pursuant to Section 6, it being agreed that the “Conversion Date” for purposes of Section 6 shall be deemed to occur on the third Trading Day following the Forced Conversion Notice Date (such third Trading Day, the “Forced Conversion Date”). The Corporation may not deliver a Forced Conversion Notice, and any Forced Conversion Notice delivered by the Corporation shall not be effective, unless all of the Equity Conditions have been met on each Trading Day during the applicable Threshold Period through and including the later of the Forced Conversion Date and the Trading Day after the date that the Conversion Shares issuable pursuant to such conversion are actually delivered to the Holders pursuant to the Forced Conversion Notice. Any Forced Conversion Notices shall be applied ratably to all of the Holders based on the then outstanding shares of Preferred Stock. For purposes of clarification, a Forced Conversion shall be subject to all of the provisions of Section 6, including, without limitation, the provisions requiring payment of liquidated damages and limitations on conversions.

Section 7. Certain Adjustments.

Stock Dividends and Stock Splits. If the Corporation, at any time while this Preferred Stock is outstanding: (i) pays a stock dividend or otherwise makes a distribution or distributions payable in shares of Common Stock on shares of Common Stock or any other Common Stock Equivalents (which, for avoidance of doubt, shall not include any shares of Common Stock issued by the Corporation upon conversion of, or payment of a dividend on, this Preferred Stock), (ii) subdivides outstanding shares of Common Stock into a larger number of shares, (iii) combines (including by way of a reverse stock split) outstanding shares of Common Stock into a smaller number of shares, or (iv) issues, in the event of a reclassification of shares of the Common Stock, any shares of capital stock of the Corporation, then the Conversion Price shall be multiplied by a fraction of which the numerator shall be the

_______________________

¹ 300% of Conversion Price

number of shares of Common Stock (excluding any treasury shares of the Corporation) outstanding immediately before such event, and of which the denominator shall be the number of shares of Common Stock outstanding immediately after such event. Any adjustment made pursuant to this Section 7(a) shall become effective immediately after the record date for the determination of stockholders entitled to receive such dividend or distribution and shall become effective immediately after the effective date in the case of a subdivision, combination or re‑classification.

a)Subsequent Rights Offerings. In addition to any adjustments pursuant to Section 7(a) above, if at any time the Corporation grants, issues or sells any Common Stock Equivalents or rights to purchase stock, warrants, securities or other property pro rata to the record holders of any class of shares of Common Stock (the “Purchase Rights”), then the Holder will be entitled to acquire, upon the terms applicable to such Purchase Rights, the aggregate Purchase Rights which the Holder could have acquired if the Holder had held the number of shares of Common Stock acquirable upon complete conversion of such Holder’s Preferred Stock (without regard to any limitations on exercise hereof, including without limitation, the Beneficial Ownership Limitation) immediately before the date on which a record is taken for the grant, issuance or sale of such Purchase Rights, or, if no such record is taken, the date as of which the record holders of shares of Common Stock are to be determined for the grant, issue or sale of such Purchase Rights (provided, however, to the extent that the Holder’s right to participate in any such Purchase Right would result in the Holder exceeding the Beneficial Ownership Limitation, then the Holder shall not be entitled to participate in such Purchase Right to such extent (or beneficial ownership of such shares of Common Stock as a result of such Purchase Right to such extent) and such Purchase Right to such extent shall be held in abeyance for the Holder until such time, if ever, as its right thereto would not result in the Holder exceeding the Beneficial Ownership Limitation).

b)Pro Rata Distributions. During such time as this Preferred Stock is outstanding, if the Corporation declares or makes any dividend or other distribution of its assets (or rights to acquire its assets) to holders of shares of Common Stock, by way of return of capital or otherwise (including, without limitation, any distribution of cash, stock or other securities, property or options by way of a dividend, spin off, reclassification, corporate rearrangement, scheme of arrangement or other similar transaction) (a “Distribution”), at any time after the issuance of this Preferred Stock, then, in each such case, the Holder shall be entitled to participate in such Distribution to the same extent that the Holder would have participated therein if the Holder had held the number of shares of Common Stock acquirable upon complete conversion of this Preferred Stock (without regard to any limitations on conversion hereof, including without limitation, the Beneficial Ownership Limitation) immediately before the date of which a record is taken for such Distribution, or, if no such record is taken, the date as of which the record holders of shares of Common Stock are to be determined for the participation in such Distribution (provided, however, to the extent that the Holder's right to participate in any such Distribution would result in the Holder exceeding the Beneficial Ownership Limitation, then the Holder shall

not be entitled to participate in such Distribution to such extent (or in the beneficial ownership of any shares of Common Stock as a result of such Distribution to such extent) and the portion of such Distribution shall be held in abeyance for the benefit of the Holder until such time, if ever, as its right thereto would not result in the Holder exceeding the Beneficial Ownership Limitation).

c)Fundamental Transaction. If, at any time while this Preferred Stock is outstanding, (i) the Corporation, directly or indirectly, in one or more related transactions effects any merger or consolidation of the Corporation with or into another Person, (ii) the Corporation, directly or indirectly, effects any sale, lease, license, assignment, transfer, conveyance or other disposition of all or substantially all of its assets in one or a series of related transactions, (iii) any, direct or indirect, purchase offer, tender offer or exchange offer (whether by the Corporation or another Person) is completed pursuant to which holders of Common Stock are permitted to sell, tender or exchange their shares for other securities, cash or property and has been accepted by the holders of 50% or more of the outstanding Common Stock, (iv) the Corporation, directly or indirectly, in one or more related transactions effects any reclassification, reorganization or recapitalization of the Common Stock or any compulsory share exchange pursuant to which the Common Stock is effectively converted into or exchanged for other securities, cash or property, or (v) the Corporation, directly or indirectly, in one or more related transactions consummates a stock or share purchase agreement or other business combination (including, without limitation, a reorganization, recapitalization, spin-off or scheme of arrangement) with another Person whereby such other Person acquires more than 50% of the outstanding shares of Common Stock (not including any shares of Common Stock held by the other Person or other Persons making or party to, or associated or affiliated with the other Persons making or party to, such stock or share purchase agreement or other business combination) (each a “Fundamental Transaction”), then, upon any subsequent conversion of this Preferred Stock, the Holder shall have the right to receive, for each Conversion Share that would have been issuable upon such conversion immediately prior to the occurrence of such Fundamental Transaction (without regard to any limitation in Section 6(d) on the conversion of this Preferred Stock), the number of shares of Common Stock of the successor or acquiring corporation or of the Corporation, if it is the surviving corporation, and any additional consideration (the “Alternate Consideration”) receivable as a result of such Fundamental Transaction by a holder of the number of shares of Common Stock for which this Preferred Stock is convertible immediately prior to such Fundamental Transaction (without regard to any limitation in Section 6(d) on the conversion of this Preferred Stock). For purposes of any such conversion, the determination of the Conversion Price shall be appropriately adjusted to apply to such Alternate Consideration based on the amount of Alternate Consideration issuable in respect of one share of Common Stock in such Fundamental Transaction, and the Corporation shall apportion the Conversion Price among the Alternate Consideration in a reasonable manner reflecting the relative value of any different components of the Alternate Consideration. If holders of Common Stock are given any choice as to the securities, cash or property to be received in a Fundamental Transaction, then the Holder shall be given the same choice as to the Alternate Consideration it receives upon any conversion of this Preferred Stock following such Fundamental Transaction. To the extent necessary to effectuate the foregoing

provisions, any successor to the Corporation or surviving entity in such Fundamental Transaction shall file a new Certificate of Designation with the same terms and conditions and issue to the Holders new preferred stock consistent with the foregoing provisions and evidencing the Holders’ right to convert such preferred stock into Alternate Consideration. The Corporation shall cause any successor entity in a Fundamental Transaction in which the Corporation is not the survivor (the “Successor Entity”) to assume in writing all of the obligations of the Corporation under this Certificate of Designation in accordance with the provisions of this Section 7(d) pursuant to written agreements in form and substance reasonably satisfactory to the Holder and approved by the Holder (without unreasonable delay) prior to such Fundamental Transaction and shall, at the option of the Holder, deliver to the Holder in exchange for this Preferred Stock a security of the Successor Entity evidenced by a written instrument substantially similar in form and substance to this Preferred Stock which is convertible for a corresponding number of shares of capital stock of such Successor Entity (or its parent entity) equivalent to the shares of Common Stock acquirable and receivable upon conversion of this Preferred Stock (without regard to any limitations on the conversion of this Preferred Stock) prior to such Fundamental Transaction, and with a conversion price which applies the conversion price hereunder to such shares of capital stock (but taking into account the relative value of the shares of Common Stock pursuant to such Fundamental Transaction and the value of such shares of capital stock, such number of shares of capital stock and such conversion price being for the purpose of protecting the economic value of this Preferred Stock immediately prior to the consummation of such Fundamental Transaction), and which is reasonably satisfactory in form and substance to the Holder. Upon the occurrence of any such Fundamental Transaction, the Successor Entity shall succeed to, and be substituted for (so that from and after the date of such Fundamental Transaction, the provisions of this Certificate of Designation referring to the “Corporation” shall refer instead to the Successor Entity), and may exercise every right and power of the Corporation and shall assume all of the obligations of the Corporation under this Certificate of Designation with the same effect as if such Successor Entity had been named as the Corporation herein.

d)Calculations. All calculations under this Section 7 shall be made to the nearest cent or the nearest 1/100th of a share, as the case may be. For purposes of this Section 7, the number of shares of Common Stock deemed to be issued and outstanding as of a given date shall be the sum of the number of shares of Common Stock (excluding any treasury shares of the Corporation) issued and outstanding.

e)Notice to the Holders.

i.Adjustment to Conversion Price. Whenever the Conversion Price is adjusted pursuant to any provision of this Section 7, the Corporation shall promptly deliver to each Holder by facsimile or email a notice setting forth the Conversion Price after such adjustment and setting forth a brief statement of the facts requiring such adjustment.

ii.Notice to Allow Conversion by Holder. If (A) the Corporation shall declare a dividend (or any other distribution in whatever form) on the Common Stock, (B) the Corporation shall declare a special nonrecurring cash dividend on or a redemption of the Common Stock, (C) the Corporation shall authorize the granting to all holders of the Common Stock of rights or warrants to subscribe for or purchase any shares of capital stock of any class or of any rights, (D) the approval of any stockholders of the Corporation shall be required in connection with any reclassification of the Common Stock, any consolidation or merger to which the Corporation is a party, any sale or transfer of all or substantially all of the assets of the Corporation, or any compulsory share exchange whereby the Common Stock is converted into other securities, cash or property or (E) the Corporation shall authorize the voluntary or involuntary dissolution, liquidation or winding up of the affairs of the Corporation, then, in each case, the Corporation shall cause to be filed at each office or agency maintained for the purpose of conversion of this Preferred Stock, and shall cause to be delivered by facsimile or email to each Holder at its last facsimile number or email address as it shall appear upon the stock books of the Corporation, at least twenty (20) calendar days prior to the applicable record or effective date hereinafter specified, a notice stating (x) the date on which a record is to be taken for the purpose of such dividend, distribution, redemption, rights or warrants, or if a record is not to be taken, the date as of which the holders of the Common Stock of record to be entitled to such dividend, distributions, redemption, rights or warrants are to be determined or (y) the date on which such reclassification, consolidation, merger, sale, transfer or share exchange is expected to become effective or close, and the date as of which it is expected that holders of the Common Stock of record shall be entitled to exchange their shares of the Common Stock for securities, cash or other property deliverable upon such reclassification, consolidation, merger, sale, transfer or share exchange, provided that the failure to deliver such notice or any defect therein or in the delivery thereof shall not affect the validity of the corporate action required to be specified in such notice. To the extent that any notice provided hereunder constitutes, or contains, material, non-public information regarding the Corporation or any of the Subsidiaries, the Corporation shall simultaneously file such notice with the Commission pursuant to a Current Report on Form 8-K. The Holder shall remain entitled to convert the Conversion Amount of this Preferred Stock (or any part hereof) during the 20-day period commencing on the date of such notice through the effective date of the event triggering such notice except as may otherwise be expressly set forth herein.

Section 8. Miscellaneous.

a)Notices.

Within the earlier of (i) two (2) Trading Days and (ii) the number of Trading Days comprising the Standard Settlement Period (as defined in Section 2(d)(i) herein) following the date of exercise as aforesaid, the Holder shall deliver the aggregate Exercise Price for the shares specified in the applicable Notice of Exercise by wire transfer or cashier’s check drawn on a United States bank unless the cashless exercise procedure specified in Section 2(c) below is specified in the applicable Notice of Exercise. No ink-original Notice of Exercise shall be required, nor shall any medallion guarantee (or other type of guarantee or notarization) of any Notice of Exercise form be required. Notwithstanding anything herein to the contrary, the Holder shall not be required to physically surrender this Warrant to the Company until the Holder has purchased all of the Warrant Shares available hereunder and the Warrant has been exercised in full, in which case, the Holder shall surrender this Warrant to the Company for cancellation within three (3) Trading Days of the date on which the final Notice of Exercise is delivered to the Company. Partial exercises of this Warrant resulting in purchases of a portion of the total number of Warrant Shares available hereunder shall have the effect of lowering the outstanding number of Warrant Shares purchasable hereunder in an amount equal to the applicable number of Warrant Shares purchased. The Holder and the Company shall maintain records showing the number of Warrant Shares purchased and the date of such purchases. The Company shall deliver any objection to any Notice of Exercise within one

(1) Business Day of receipt of such notice. The Holder and any assignee, by acceptance of this Warrant, acknowledge and agree that, by reason of the provisions of this paragraph, following the purchase of a portion of the Warrant Shares hereunder, the number of Warrant Shares available for purchase hereunder at any given time may be less than the amount stated on the face hereof.

Notwithstanding the foregoing in this Section 2(a), a holder whose interest in this Warrant is a beneficial interest in certificate(s) representing this Warrant held in book-entry form through DTC (or another established clearing corporation performing similar functions), shall effect exercises made pursuant to this Section 2(a) by delivering to DTC (or such other clearing corporation, as applicable) the appropriate instruction form for exercise, complying with the procedures to effect exercise that are required by DTC (or such other clearing corporation, as applicable), subject to a Holder’s right to elect to receive a Warrant in certificated form pursuant to the terms of the Warrant Agency Agreement, in which case this sentence shall not apply.

b)Exercise Price. The exercise price per share of Common Stock under this Warrant shall be $_____, subject to adjustment hereunder (the “Exercise Price”).

c)Cashless Exercise. If at the time of exercise hereof there is no effective registration statement registering, or the prospectus contained therein is not available for the issuance of the Warrant Shares to the Holder, then this Warrant may also be exercised, in whole or in part, at such time by means of a “cashless exercise” in which the Holder shall be entitled to receive a number of Warrant Shares equal to the quotient obtained by dividing [(A-B) (X)] by (A), where:

(A) = as applicable: (i) the VWAP on the Trading Day immediately preceding the date of the applicable Notice of Exercise if such Notice of Exercise is (1) both executed and delivered pursuant to Section 2(a) hereof on a day that is not a Trading Day or (2) both executed and delivered pursuant to Section 2(a) hereof on a Trading Day prior to the opening of “regular trading hours” (as defined in Rule 600(b)(64) of Regulation NMS promulgated under the federal securities laws) on such Trading Day, (ii) at the option of the Holder, either (y) the VWAP on the Trading Day immediately preceding the date of the applicable Notice of Exercise or (z) the Bid Price of the Common Stock on the principal Trading Market as reported by Bloomberg L.P. as of the time of the Holder’s execution of the applicable Notice of Exercise if such Notice of Exercise is executed during “regular trading hours” on a Trading Day and is delivered within two (2) hours thereafter (including until two (2) hours after the close of “regular

trading hours” on a Trading Day) pursuant to Section 2(a) hereof or (iii) the VWAP on the date of the applicable Notice of Exercise if the date of such Notice of Exercise is a Trading Day and such Notice of Exercise is both executed and delivered pursuant to Section 2(a) hereof after the close of “regular trading hours” on such Trading Day;

(B) = the Exercise Price of this Warrant, as adjusted hereunder; and

(X) = the number of Warrant Shares that would be issuable upon exercise of this Warrant in accordance with the terms of this Warrant if such exercise were by means of a cash exercise rather than a cashless exercise.

If Warrant Shares are issued in such a cashless exercise, the parties acknowledge and agree that in accordance with Section 3(a)(9) of the Securities Act, the Warrant Shares shall take on the registered characteristics of the Warrants being exercised. The Company agrees not to take any position contrary to this Section 2(c).

Notwithstanding anything herein to the contrary, on the Termination Date, this Warrant shall be automatically exercised via cashless exercise pursuant to this Section 2(c).

Notwithstanding the foregoing, and without limiting the rights of the Holder under Sections 2(d)(i) and 2(d)(iv), in no event will the Company be required to net cash settle an exercise of this Warrant.

d)Mechanics of Exercise.

Delivery of Warrant Shares Upon Exercise. Warrant Shares purchased hereunder shall be transmitted by the Transfer Agent to the Holder by crediting the account of the Holder’s or its designee’s balance account with The Depository Trust Company through its Deposit or Withdrawal at Custodian system (“DWAC”) if the Company is then a participant in such system and either (A) there is an effective registration statement permitting the issuance of the Warrant Shares to or resale of the Warrant Shares by Holder or (B) this Warrant is being exercised via cashless exercise, and otherwise by physical delivery of a certificate, registered in the Company’s share register in the name of the Holder or its designee, for the number of Warrant Shares to which the Holder is entitled pursuant to such exercise to the address specified by the Holder in the Notice of Exercise by the date that is the earliest of (i) two (2) Trading Days after the delivery to the Company of the Notice of Exercise, (ii) one (1) Trading Day after delivery of the aggregate Exercise Price to the Company and (iii) the number of Trading

Days comprising the Standard Settlement Period after the delivery to the Company of the Notice of Exercise (such date, the “Warrant Share Delivery Date”). Upon delivery of the Notice of Exercise, the Holder shall be deemed for all corporate purposes to have become the holder of record of the Warrant Shares with respect to which this Warrant has been exercised, irrespective of the date of delivery of the Warrant Shares, provided that payment of the aggregate Exercise Price (other than in the case of a cashless exercise) is received within the earlier of (i) two (2) Trading Days and (ii) the number of Trading Days comprising the Standard Settlement Period following delivery of the Notice of Exercise. If the Company fails for any reason to deliver to the Holder the Warrant Shares subject to a Notice of Exercise by the Warrant Share Delivery Date, the Company shall pay to the Holder, in cash, as liquidated damages and not as a penalty, for each $1,000 of Warrant Shares subject to such exercise (based on the VWAP of the Common Stock on the date of the applicable Notice of Exercise), $5 per Trading Day (increasing to $10 per Trading Day on the fifth Trading Day after such liquidated damages begin to accrue) for each Trading Day after such Warrant Share Delivery Date until such Warrant Shares are delivered or Holder rescinds such exercise. The Company agrees to maintain a transfer agent that is a participant in the FAST program so long as this Warrant remains outstanding and exercisable. As used herein, “Standard Settlement Period” means the standard settlement period, expressed in a number of Trading Days, on the Company’s primary Trading Market with respect to the Common Stock as in effect on the date of delivery of the Notice of Exercise.

ii. Delivery of New Warrants Upon Exercise. If this Warrant shall have been exercised in part, the Company shall, at the request of a Holder and upon surrender of this Warrant, at the time of delivery of the Warrant Shares, deliver to the Holder a new Warrant evidencing the rights of the Holder to purchase the unpurchased Warrant Shares called for by this Warrant, which new Warrant shall in all other respects be identical with this Warrant.

iii. Rescission Rights. If the Company fails to cause the Transfer Agent to transmit to the Holder the Warrant Shares pursuant to Section 2(d)(i) by the Warrant Share Delivery Date, then the Holder will have the right to rescind such exercise.

iv. Compensation for Buy-In on Failure to Timely Deliver Warrant Shares Upon Exercise. In addition to any other rights available to the Holder, if the Company fails to cause the Transfer Agent to transmit to the Holder the Warrant Shares in accordance with the provisions of Section 2(d)(i) above pursuant to an exercise on or before the Warrant Share Delivery Date, and if after such date the Holder is required by its broker to purchase (in an open market transaction or otherwise) or the Holder’s brokerage firm otherwise purchases, shares of Common Stock to deliver in satisfaction of a sale by the Holder of the Warrant Shares which the Holder anticipated receiving upon such exercise (a “Buy-In”), then the Company shall (A) pay in cash to the Holder the amount, if any, by which (x) the Holder’s total purchase price (including brokerage commissions, if any) for the shares of Common Stock so purchased exceeds (y) the amount obtained by multiplying (1) the number of Warrant Shares that the Company was required to deliver to the Holder in connection with the exercise at issue times (2) the price at which the sell order giving rise to such purchase obligation was executed, and (B) at the option of the Holder, either reinstate the portion of the Warrant and equivalent number of Warrant Shares for which such exercise was not honored (in which case such exercise shall be deemed rescinded) or deliver to the Holder the number of shares of Common Stock that would have been issued had the Company timely complied with its exercise and delivery obligations hereunder. For example, if the Holder purchases Common Stock having a total purchase price of $11,000 to cover a Buy-In with respect to an attempted exercise of shares of Common Stock with an aggregate sale price giving rise to such purchase obligation of $10,000, under clause (A) of the immediately preceding sentence the Company shall be required to pay the Holder $1,000. The Holder shall provide the Company written notice indicating the amounts payable to the Holder in respect of the Buy-In and, upon request of the Company, evidence of the amount of such loss. Nothing herein shall limit a Holder’s right to pursue any other remedies available to it hereunder, at law or in equity including, without limitation, a decree of specific performance and/or injunctive relief with respect to the Company’s failure to timely deliver shares of Common Stock upon exercise of the Warrant as required pursuant to the terms hereof.

v. No Fractional Shares or Scrip. No fractional shares or scrip representing fractional shares shall be issued upon the exercise of this Warrant. As to any fraction of a share which the Holder would otherwise be

entitled to purchase upon such exercise, the Company shall round up to the next whole share.

vi. Charges, Taxes and Expenses. Issuance of Warrant Shares shall be made without charge to the Holder for any issue or transfer tax or other incidental expense in respect of the issuance of such Warrant Shares, all of which taxes and expenses shall be paid by the Company, and such Warrant Shares shall be issued in the name of the Holder or in such name or names as may be directed by the Holder; provided, however, that in the event that Warrant Shares are to be issued in a name other than the name of the Holder, this Warrant when surrendered for exercise shall be accompanied by the Assignment Form attached hereto duly executed by the Holder and the Company may require, as a condition thereto, the payment of a sum sufficient to reimburse it for any transfer tax incidental thereto. The Company shall pay all Transfer Agent fees required for same-day processing of any Notice of Exercise and all fees to the Depository Trust Company (or another established clearing corporation performing similar functions) required for same-day electronic delivery of the Warrant Shares.

vii. Closing of Books. The Company will not close its stockholder books or records in any manner which prevents the timely exercise of this Warrant, pursuant to the terms hereof.

e)Holder’s Exercise Limitations. The Company shall not effect any exercise of this Warrant, and a Holder shall not have the right to exercise any portion of this Warrant, pursuant to Section 2 or otherwise, to the extent that after giving effect to such issuance after exercise as set forth on the applicable Notice of Exercise, the Holder (together with the Holder’s Affiliates, and any other Persons acting as a group together with the Holder or any of the Holder’s Affiliates (such Persons, “Attribution Parties”)), would beneficially own in excess of the Beneficial Ownership Limitation (as defined below). For purposes of the foregoing sentence, the number of shares of Common Stock beneficially owned by the Holder and its Affiliates and Attribution Parties shall include the number of shares of Common Stock issuable upon exercise of this Warrant with respect to which such determination is being made, but shall exclude the number of shares of Common Stock which would be issuable upon (i) exercise of the remaining, nonexercised portion of this Warrant beneficially owned by the Holder or any of its Affiliates or Attribution Parties and (ii) exercise or conversion of the unexercised or nonconverted portion of any other securities of the Company (including, without limitation, any other Common Stock Equivalents) subject to a limitation on conversion or exercise analogous to the limitation contained herein

beneficially owned by the Holder or any of its Affiliates or Attribution Parties. Except as set forth in the preceding sentence, for purposes of this Section 2(e), beneficial ownership shall be calculated in accordance with Section 13(d) of the Exchange Act and the rules and regulations promulgated thereunder. Subject to the Holder's right to rely on the number of outstanding shares of Common Stock set forth below, it being acknowledged by the Holder that the Company is not representing to the Holder that such calculation is in compliance with Section 13(d) of the Exchange Act and the Holder is solely responsible for any schedules required to be filed in accordance therewith. To the extent that the limitation contained in this Section 2(e) applies, the determination of whether this Warrant is exercisable (in relation to other securities owned by the Holder together with any Affiliates and Attribution Parties) and of which portion of this Warrant is exercisable shall be in the sole discretion of the Holder, and the submission of a Notice of Exercise shall be deemed to be the Holder’s determination of whether this Warrant is exercisable (in relation to other securities owned by the Holder together with any Affiliates and Attribution Parties) and of which portion of this Warrant is exercisable, in each case subject to the Beneficial Ownership Limitation. To ensure compliance with this restriction, each Holder shall be deemed to represent to the Company each time it delivers a Notice of Exercise that such Notice of Exercise has not violated the restrictions set forth in this paragraph, and the Company shall have no obligation to verify or confirm the accuracy of such determination. In addition, a determination as to any group status as contemplated above shall be determined in accordance with Section 13(d) of the Exchange Act and the rules and regulations promulgated thereunder. For purposes of this Section 2(e), in determining the number of outstanding shares of Common Stock, a Holder may rely on the number of outstanding shares of Common Stock as reflected in (A) the Company’s most recent periodic or annual report filed with the Commission, as the case may be, (B) a more recent public announcement by the Company or (C) a more recent written notice by the Company or the Transfer Agent setting forth the number of shares of Common Stock outstanding. Upon the written or oral request of a Holder, the Company shall within two Trading Days confirm orally and in writing to the Holder the number of shares of Common Stock then outstanding. In any case, the number of outstanding shares of Common Stock shall be determined after giving effect to the conversion or exercise of securities of the Company, including this Warrant, by the Holder or its Affiliates or Attribution Parties since the date as of which such number of outstanding shares of Common Stock was reported. The “Beneficial Ownership Limitation” shall be 4.99% (or, upon election by a Holder prior to the issuance of any Warrants, 9.99%) of the number of shares of the Common Stock outstanding immediately after giving effect to the issuance of shares of Common Stock issuable upon exercise of this Warrant. The Holder, upon notice to the Company, may increase or decrease the Beneficial Ownership Limitation provisions of this

Section 2(e), provided that the Beneficial Ownership Limitation in no event exceeds 9.99% of the number of shares of the Common Stock outstanding immediately after giving effect to the issuance of shares of Common Stock upon exercise of this Warrant held by the Holder and the provisions of this Section 2(e) shall continue to apply. Any increase in the Beneficial Ownership Limitation will not be effective until the 61^st day after such notice is delivered to the Company. The provisions of this paragraph shall be construed and implemented in a manner otherwise than in strict conformity with the terms of this Section 2(e) to correct this paragraph (or any portion hereof) which may be defective or inconsistent with the intended Beneficial Ownership Limitation herein contained or to make changes or supplements necessary or desirable to properly give effect to such limitation. The limitations contained in this paragraph shall apply to a successor holder of this Warrant.

f)Call Provision. Subject to the provisions of Section 2(e) and this Section 2(f), if, after the Initial Exercise Date, (i) the VWAP for each of 20 consecutive Trading Days (the “Measurement Period,” which 20 consecutive Trading Day period shall not have commenced until after the Initial Exercise Date) exceeds $____³ (subject to adjustment for forward and reverse stock splits, recapitalizations, stock dividends and the like after the Initial Exercise Date), (ii) the average daily volume for such Measurement Period exceeds $175,000 per Trading Day and (iii) the Holder is not in possession of any information that constitutes, or might constitute, material non-public information which was provided by the Company, any of its Subsidiaries, or any of their officers, directors, employees, agents or Affiliates, then the Company may, within 1 Trading Day of the end of such Measurement Period, call for cancellation of all or any portion of this Warrant for which a Notice of Exercise has not yet been delivered (such right, a “Call”) for consideration equal to $0.001 per Warrant Share. To exercise this right, the Company must deliver to the Holder an irrevocable written notice (a “Call Notice”), indicating therein the portion of unexercised portion of this Warrant to which such notice applies. If the conditions set forth below for such Call are satisfied from the period from the date of the Call Notice through and including the Call Date (as defined below), then any portion of this Warrant subject to such Call Notice for which a Notice of Exercise shall not have been received by the Call Date will be cancelled at 6:30 p.m. (New York City time) on the tenth Trading Day after the date the Call Notice is received by the Holder (such date and time, the “Call Date”). Any unexercised portion of this Warrant to which the Call Notice does not pertain will be unaffected by such Call Notice. In furtherance thereof, the Company covenants and agrees that it will honor all Notices of Exercise with respect to Warrant Shares subject to a Call Notice that are tendered through 6:30 p.m. (New York City time) on the Call Date. The parties agree that any Notice

of Exercise delivered following a Call Notice which calls less than all of the Warrants shall first reduce to zero the number of Warrant Shares subject to such Call Notice prior to reducing the remaining Warrant Shares available for purchase under this Warrant. For example, if (A) this Warrant then permits the Holder to acquire 100 Warrant Shares, (B) a Call Notice pertains to 75 Warrant Shares, and (C) prior to 6:30 p.m. (New York City time) on the Call Date the Holder tenders a Notice of Exercise in respect of 50 Warrant Shares, then (x) on the Call Date the right under this Warrant to acquire 25 Warrant Shares will be automatically cancelled, (y) the Company, in the time and manner required under this Warrant, will have issued and delivered to the Holder 50 Warrant Shares in respect of the exercises following receipt of the Call Notice, and (z) the Holder may, until the Termination Date, exercise this Warrant for 25 Warrant Shares (subject to adjustment as herein provided and subject to subsequent Call Notices). Subject again to the provisions of this Section 2(f), the Company may deliver subsequent Call Notices for any portion of this Warrant for which the Holder shall not have delivered a Notice of Exercise. Notwithstanding anything to the contrary set forth in this Warrant, the Company may not deliver a Call Notice or require the cancellation of this Warrant (and any such Call Notice shall be void), unless, from the beginning of the Measurement Period through the Call Date, (1) the Company shall have honored in accordance with the terms of this Warrant all Notices of Exercise delivered by 6:30 p.m. (New York City time) on the Call Date, and (2) a registration statement shall be effective as to all Warrant Shares and the prospectus thereunder available for use by the Company for the sale of all such Warrant Shares to the Holder, and (3) the Common Stock shall be listed or quoted for trading on the Trading Market, and (4) there is a sufficient number of authorized shares of Common Stock for issuance of all Warrant Shares, and (5) the issuance of all Warrant Shares subject to a Call Notice shall not cause a breach of any provision of Section 2(e) herein. The Company’s right to call the Warrants under this Section 2(f) shall be exercised ratably among the Holders based on each Holder’s initial purchase of Warrants.

Section 3. Certain Adjustments.

a)Stock Dividends and Splits. If the Company, at any time while this Warrant is outstanding: (i) pays a stock dividend or otherwise makes a distribution or distributions on shares of its Common Stock or any other equity or equity equivalent securities payable in shares of Common Stock (which, for avoidance of doubt, shall not include any shares of Common Stock issued by the Company upon exercise of this Warrant), (ii) subdivides outstanding shares of Common Stock into a larger number of shares, (iii) combines (including by way of reverse stock split) outstanding shares of Common Stock into a smaller number of shares, or (iv) issues by reclassification of shares of the Common Stock any

shares of capital stock of the Company, then in each case the Exercise Price shall be multiplied by a fraction of which the numerator shall be the number of shares of Common Stock (excluding treasury shares, if any) outstanding immediately before such event and of which the denominator shall be the number of shares of Common Stock outstanding immediately after such event, and the number of shares issuable upon exercise of this Warrant shall be proportionately adjusted such that the aggregate Exercise Price of this Warrant shall remain unchanged. Any adjustment made pursuant to this Section 3(a) shall become effective immediately after the record date for the determination of stockholders entitled to receive such dividend or distribution and shall become effective immediately after the effective date in the case of a subdivision, combination or re‑classification.

b)Subsequent Rights Offerings. In addition to any adjustments pursuant to Section 3(a) above, if at any time the Company grants, issues or sells any Common Stock Equivalents or rights to purchase stock, warrants, securities or other property pro rata to the record holders of any class of shares of Common Stock (the “Purchase Rights”), then the Holder will be entitled to acquire, upon the terms applicable to such Purchase Rights, the aggregate Purchase Rights which the Holder could have acquired if the Holder had held the number of shares of Common Stock acquirable upon complete exercise of this Warrant (without regard to any limitations on exercise hereof, including without limitation, the Beneficial Ownership Limitation) immediately before the date on which a record is taken for the grant, issuance or sale of such Purchase Rights, or, if no such record is taken, the date as of which the record holders of shares of Common Stock are to be determined for the grant, issue or sale of such Purchase Rights (provided, however, to the extent that the Holder’s right to participate in any such Purchase Right would result in the Holder exceeding the Beneficial Ownership Limitation, then the Holder shall not be entitled to participate in such Purchase Right to such extent (or beneficial ownership of such shares of Common Stock as a result of such Purchase Right to such extent) and such Purchase Right to such extent shall be held in abeyance for the Holder until such time, if ever, as its right thereto would not result in the Holder exceeding the Beneficial Ownership Limitation).

c)Pro Rata Distributions. During such time as this Warrant is outstanding, if the Company shall declare or make any dividend or other distribution of its assets (or rights to acquire its assets) to holders of shares of Common Stock, by way of return of capital or otherwise (including, without limitation, any distribution of cash, stock or other securities, property or options by way of a dividend, spin off, reclassification, corporate rearrangement, scheme of arrangement or other similar transaction) (a "Distribution"), at any time after the issuance of this Warrant, then, in each such case, the Holder shall be entitled to participate in such Distribution to the same extent that the Holder would have participated therein if

the Holder had held the number of shares of Common Stock acquirable upon complete exercise of this Warrant (without regard to any limitations on exercise hereof, including without limitation, the Beneficial Ownership Limitation) immediately before the date of which a record is taken for such Distribution, or, if no such record is taken, the date as of which the record holders of shares of Common Stock are to be determined for the participation in such Distribution (provided, however, to the extent that the Holder's right to participate in any such Distribution would result in the Holder exceeding the Beneficial Ownership Limitation, then the Holder shall not be entitled to participate in such Distribution to such extent (or in the beneficial ownership of any shares of Common Stock as a result of such Distribution to such extent) and the portion of such Distribution shall be held in abeyance for the benefit of the Holder until such time, if ever, as its right thereto would not result in the Holder exceeding the Beneficial Ownership Limitation). To the extent that this Warrant has not been partially or completely exercised at the time of such Distribution, such portion of the Distribution shall be held in abeyance for the benefit of the Holder until the Holder has exercised this Warrant.

d)Fundamental Transaction. If, at any time while this Warrant is outstanding, (i) the Company, directly or indirectly, in one or more related transactions effects any merger or consolidation of the Company with or into another Person, (ii) the Company, directly or indirectly, effects any sale, lease, license, assignment, transfer, conveyance or other disposition of all or substantially all of its assets in one or a series of related transactions, (iii) any, direct or indirect, purchase offer, tender offer or exchange offer (whether by the Company or another Person) is completed pursuant to which holders of Common Stock are permitted to sell, tender or exchange their shares for other securities, cash or property and has been accepted by the holders of 50% or more of the outstanding Common Stock, (iv) the Company, directly or indirectly, in one or more related transactions effects any reclassification, reorganization or recapitalization of the Common Stock or any compulsory share exchange pursuant to which the Common Stock is effectively converted into or exchanged for other securities, cash or property, or (v) the Company, directly or indirectly, in one or more related transactions consummates a stock or share purchase agreement or other business combination (including, without limitation, a reorganization, recapitalization, spin-off, merger or scheme of arrangement) with another Person or group of Persons whereby such other Person or group acquires more than 50% of the outstanding shares of Common Stock (not including any shares of Common Stock held by the other Person or other Persons making or party to, or associated or affiliated with the other Persons making or party to, such stock or share purchase agreement or other business combination) (each a “Fundamental Transaction”), then, upon any subsequent exercise of this Warrant, the Holder shall have the right to receive, for each Warrant Share that would have been issuable upon such exercise

immediately prior to the occurrence of such Fundamental Transaction, at the option of the Holder (without regard to any limitation in Section 2(e) on the exercise of this Warrant), the number of shares of Common Stock of the successor or acquiring corporation or of the Company, if it is the surviving corporation, and any additional consideration (the “Alternate Consideration”) receivable as a result of such Fundamental Transaction by a holder of the number of shares of Common Stock for which this Warrant is exercisable immediately prior to such Fundamental Transaction (without regard to any limitation in Section 2(e) on the exercise of this Warrant). For purposes of any such exercise, the determination of the Exercise Price shall be appropriately adjusted to apply to such Alternate Consideration based on the amount of Alternate Consideration issuable in respect of one share of Common Stock in such Fundamental Transaction, and the Company shall apportion the Exercise Price among the Alternate Consideration in a reasonable manner reflecting the relative value of any different components of the Alternate Consideration. If holders of Common Stock are given any choice as to the securities, cash or property to be received in a Fundamental Transaction, then the Holder shall be given the same choice as to the Alternate Consideration it receives upon any exercise of this Warrant following such Fundamental Transaction. Notwithstanding anything to the contrary, in the event of a Fundamental Transaction, the Company or any Successor Entity (as defined below) shall, at the Holder’s option, exercisable at any time concurrently with, or within 30 days after, the consummation of the Fundamental Transaction (or, if later, the date of the public announcement of the applicable Fundamental Transaction), purchase this Warrant from the Holder by paying to the Holder an amount of cash equal to the Black Scholes Value (as defined below) of the remaining unexercised portion of this Warrant on the date of the consummation of such Fundamental Transaction; provided, however, that if the Fundamental Transaction is not within the Company's control, including not approved by the Company's Board of Directors, Holder shall only be entitled to receive from the Company or any Successor Entity, as of the date of consummation of such Fundamental Transaction, the same type or form of consideration (and in the same proportion), at the Black Scholes Value of the unexercised portion of this Warrant, that is being offered and paid to the holders of Common Stock of the Company in connection with the Fundamental Transaction, whether that consideration be in the form of cash, stock or any combination thereof, or whether the holders of Common Stock are given the choice to receive from among alternative forms of consideration connection with the Fundamental Transaction). “Black Scholes Value” means the value of this Warrant based on the Black-Scholes Option Pricing Model obtained from the “OV” function on Bloomberg, L.P. (“Bloomberg”) determined as of the day of consummation of the applicable Fundamental Transaction for pricing purposes and reflecting (A) a risk-free interest rate corresponding to the U.S. Treasury rate for a period equal to the time between the date of

the public announcement of the applicable Fundamental Transaction and the Termination Date, (B) an expected volatility equal to the greater of 100% and the 100 day volatility obtained from the HVT function on Bloomberg (determined utilizing a 365 day annualization factor) as of the Trading Day immediately following the public announcement of the applicable Fundamental Transaction, (C) the underlying price per share used in such calculation shall be the greater of (i) the sum of the price per share being offered in cash, if any, plus the value of any non-cash consideration, if any, being offered in such Fundamental Transaction and (ii) the greater of (x) the last VWAP immediately prior to the public announcement of such Fundamental Transaction and (y) the last VWAP immediately prior to the consummation of such Fundamental Transaction and (D) a remaining option time equal to the time between the date of the public announcement of the applicable Fundamental Transaction and the Termination Date. The payment of the Black Scholes Value will be made by wire transfer of immediately available funds within five Business Days of teh Holder's election (or, if later, on the effective date of the Fundamental Transaction). The Company shall cause any successor entity in a Fundamental Transaction in which the Company is not the survivor (the “Successor Entity”) to assume in writing all of the obligations of the Company under this Warrant in accordance with the provisions of this Section 3(d) pursuant to written agreements in form and substance reasonably satisfactory to the Holder and approved by the Holder (without unreasonable delay) prior to such Fundamental Transaction and shall, at the option of the Holder, deliver to the Holder in exchange for this Warrant a security of the Successor Entity evidenced by a written instrument substantially similar in form and substance to this Warrant which is exercisable for a corresponding number of shares of capital stock of such Successor Entity (or its parent entity) equivalent to the shares of Common Stock acquirable and receivable upon exercise of this Warrant (without regard to any limitations on the exercise of this Warrant) prior to such Fundamental Transaction, and with an exercise price which applies the exercise price hereunder to such shares of capital stock (but taking into account the relative value of the shares of Common Stock pursuant to such Fundamental Transaction and the value of such shares of capital stock, such number of shares of capital stock and such exercise price being for the purpose of protecting the economic value of this Warrant immediately prior to the consummation of such Fundamental Transaction), and which is reasonably satisfactory in form and substance to the Holder. Upon the occurrence of any such Fundamental Transaction, the Successor Entity shall succeed to, and be substituted for (so that from and after the date of such Fundamental Transaction, the provisions of this Warrant referring to the “Company” shall refer instead to the Successor Entity), and may exercise every right and power of the Company and shall assume all of the obligations of the Company under this Warrant with the same effect as if such Successor Entity had been named as the Company herein.

e)Calculations. All calculations under this Section 3 shall be made to the nearest cent or the nearest 1/100th of a share, as the case may be. For purposes of this Section 3, the number of shares of Common Stock deemed to be issued and outstanding as of a given date shall be the sum of the number of shares of Common Stock (excluding treasury shares, if any) issued and outstanding.

f)Notice to Holder.

i. Adjustment to Exercise Price. Whenever the Exercise Price is adjusted pursuant to any provision of this Section 3, the Company shall promptly deliver to the Holder by facsimile or email a notice setting forth the Exercise Price after such adjustment and any resulting adjustment to the number of Warrant Shares and setting forth a brief statement of the facts requiring such adjustment.

ii. Notice to Allow Exercise by Holder. If (A) the Company shall declare a dividend (or any other distribution in whatever form) on the Common Stock, (B) the Company shall declare a special nonrecurring cash dividend on or a redemption of the Common Stock, (C) the Company shall authorize the granting to all holders of the Common Stock rights or warrants to subscribe for or purchase any shares of capital stock of any class or of any rights, (D) the approval of any stockholders of the Company shall be required in connection with any reclassification of the Common Stock, any consolidation or merger to which the Company is a party, any sale or transfer of all or substantially all of the assets of the Company, or any compulsory share exchange whereby the Common Stock is converted into other securities, cash or property, or (E) the Company shall authorize the voluntary or involuntary dissolution, liquidation or winding up of the affairs of the Company, then, in each case, the Company shall cause to be delivered by facsimile or email to the Holder at its last facsimile number or email address as it shall appear upon the Warrant Register of the Company, at least 20 calendar days prior to the applicable record or effective date hereinafter specified, a notice stating (x) the date on which a record is to be taken for the purpose of such dividend, distribution, redemption, rights or warrants, or if a record is not to be taken, the date as of which the holders of the Common Stock of record to be entitled to such dividend, distributions, redemption, rights or warrants are to be determined or (y) the date on which such reclassification, consolidation, merger, sale, transfer or share exchange is

expected to become effective or close, and the date as of which it is expected that holders of the Common Stock of record shall be entitled to exchange their shares of the Common Stock for securities, cash or other property deliverable upon such reclassification, consolidation, merger, sale, transfer or share exchange; provided that the failure to deliver such notice or any defect therein or in the delivery thereof shall not affect the validity of the corporate action required to be specified in such notice. To the extent that any notice provided in this Warrant constitutes, or contains, material, non-public information regarding the Company or any of the Subsidiaries, the Company shall simultaneously file such notice with the Commission pursuant to a Current Report on Form 8-K. The Holder shall remain entitled to exercise this Warrant during the period commencing on the date of such notice to the effective date of the event triggering such notice except as may otherwise be expressly set forth herein.

Section 4. Transfer of Warrant.

a)Transferability. Subject to compliance with any applicable securities laws, this Warrant and all rights hereunder (including, without limitation, any registration rights) are transferable, in whole or in part, upon surrender of this Warrant at the principal office of the Company or its designated agent, together with a written assignment of this Warrant substantially in the form attached hereto duly executed by the Holder or its agent or attorney and funds sufficient to pay any transfer taxes payable upon the making of such transfer. Upon such surrender and, if required, such payment, the Company shall execute and deliver a new Warrant or Warrants in the name of the assignee or assignees, as applicable, and in the denomination or denominations specified in such instrument of assignment, and shall issue to the assignor a new Warrant evidencing the portion of this Warrant not so assigned, and this Warrant shall promptly be cancelled. Notwithstanding anything herein to the contrary, the Holder shall not be required to physically surrender this Warrant to the Company unless the Holder has assigned this Warrant in full, in which case, the Holder shall surrender this Warrant to the Company within three (3) Trading Days of the date the Holder delivers an assignment form to the Company assigning this Warrant in full. The Warrant, if properly assigned in accordance herewith, may be exercised by a new holder for the purchase of Warrant Shares without having a new Warrant issued.

b)New Warrants. If this Warrant is not held in global form through DTC (or any successor depositary), this Warrant may be divided or combined with other Warrants upon presentation hereof at the aforesaid office of the Company, together with a written

notice specifying the names and denominations in which new Warrants are to be issued, signed by the Holder or its agent or attorney. Subject to compliance with Section 4(a), as to any transfer which may be involved in such division or combination, the Company shall execute and deliver a new Warrant or Warrants in exchange for the Warrant or Warrants to be divided or combined in accordance with such notice. All Warrants issued on transfers or exchanges shall be dated the initial issuance date of this Warrant and shall be identical with this Warrant except as to the number of Warrant Shares issuable pursuant thereto.

c)Warrant Register. The Company shall register this Warrant, upon records to be maintained by the Warrant Agent for that purpose (the “Warrant Register”), in the name of the record Holder hereof from time to time. The Company and the Warrant Agent may deem and treat the registered Holder of this Warrant as the absolute owner hereof for the purpose of any exercise hereof or any distribution to the Holder, and for all other purposes, absent actual notice to the contrary.

Section 5. Miscellaneous.

a)No Rights as Stockholder Until Exercise. This Warrant does not entitle the Holder to any voting rights, dividends or other rights as a stockholder of the Company prior to the exercise hereof as set forth in Section 2(d)(i), except as expressly set forth in Section 3. Without limiting any rights of a Holder to receive Warrant Shares on a “cashless exercise” pursuant to Section 2(c) or to receive cash payments pursuant to Section 2(d)(i) and Section 2(d)(iv) herein, in no event shall the Company be required to net cash settle an exercise of this Warrant.

b)Loss, Theft, Destruction or Mutilation of Warrant. The Company covenants that upon receipt by the Company or the Warrant Agent of evidence reasonably satisfactory to it of the loss, theft, destruction or mutilation of this Warrant or any stock certificate relating to the Warrant Shares, and in case of loss, theft or destruction, of indemnity or security reasonably satisfactory to it (which, in the case of the Warrant, shall not include the posting of any bond), and upon surrender and cancellation of such Warrant or stock certificate, if mutilated, the Company will make and deliver a new Warrant or stock certificate of like tenor and dated as of such cancellation, in lieu of such Warrant or stock certificate.

c)Saturdays, Sundays, Holidays, etc. If the last or appointed day for the taking of any action or the expiration of any right required or granted herein shall not be a Business Day, then, such action may be taken or such right may be exercised on the next succeeding Business Day.

d)Authorized Shares. The Company covenants that, from and after the Authorized Share Increase Date, during the period the Warrant is outstanding, it will reserve from its authorized and unissued Common Stock a sufficient number of shares to provide for the issuance of the Warrant Shares upon the exercise of any purchase rights under this Warrant. The Company further covenants that its issuance of this Warrant shall constitute full authority to its officers who are charged with the duty of issuing the necessary Warrant Shares upon the exercise of the purchase rights under this Warrant. The Company will take all such reasonable action as may be necessary to assure that such Warrant Shares may be issued as provided herein without violation of any applicable law or regulation, or of any requirements of the Trading Market upon which the Common Stock may be listed. The Company covenants that all Warrant Shares which may be issued upon the exercise of the purchase rights represented by this Warrant will, upon exercise of the purchase rights represented by this Warrant and payment for such Warrant Shares in accordance herewith, be duly authorized, validly issued, fully paid and nonassessable and free from all taxes, liens and charges created by the Company in respect of the issue thereof (other than taxes in respect of any transfer occurring contemporaneously with such issue).

Except and to the extent as waived or consented to by the Holder, the Company shall not by any action, including, without limitation, amending its certificate of incorporation or through any reorganization, transfer of assets, consolidation, merger, dissolution, issue or sale of securities or any other voluntary action, avoid or seek to avoid the observance or performance of any of the terms of this Warrant, but will at all times in good faith assist in the carrying out of all such terms and in the taking of all such actions as may be necessary or appropriate to protect the rights of Holder as set forth in this Warrant against impairment. Without limiting the generality of the foregoing, the Company will (i) not increase the par value of any Warrant Shares above the amount payable therefor upon such exercise immediately prior to such increase in par value, (ii) take all such action as may be necessary or appropriate in order that the Company may validly and legally issue fully paid and nonassessable Warrant Shares upon the exercise of this Warrant and (iii) use commercially reasonable efforts to obtain all such authorizations, exemptions or consents from any public regulatory body having jurisdiction thereof, as may be, necessary to enable the Company to perform its obligations under this Warrant.

Before taking any action which would result in an adjustment in the number of Warrant Shares for which this Warrant is exercisable or in the Exercise Price, the Company shall obtain all such authorizations or exemptions thereof, or consents thereto, as may be necessary from any public regulatory body or bodies having jurisdiction thereof.

e)Governing Law. All questions concerning the construction, validity, enforcement and interpretation of this Warrant shall be governed by and construed and enforced in accordance with the internal laws of the State of New York, without regard to the principles of conflicts of law thereof. Each party agrees that all legal proceedings concerning the interpretations, enforcement and defense of the transactions contemplated by this Warrant (whether brought against a party hereto or their respective affiliates, directors, officers, shareholders, partners, members, employees or agents) shall be commenced exclusively in the state and federal courts sitting in the City of New York. Each party hereby irrevocably submits to the exclusive jurisdiction of the state and federal courts sitting in the City of New York, Borough of Manhattan for the adjudication of any dispute hereunder or in connection herewith or with any transaction contemplated hereby or discussed herein, and hereby irrevocably waives, and agrees not to assert in any suit, action or proceeding, any claim that it is not personally subject to the jurisdiction of any such court, that such suit, action or proceeding is improper or is an inconvenient venue for such proceeding. Each party hereby irrevocably waives personal service of process and consents to process being served in any such suit, action or proceeding by mailing a copy thereof via registered or certified mail or overnight delivery (with evidence of delivery) to such party at the address in effect for notices to it under this Warrant and agrees that such service shall constitute good and sufficient service of process and notice thereof. Nothing contained herein shall be deemed to limit in any way any right to serve process in any other manner permitted by law. If either party shall commence an action, suit or proceeding to enforce any provisions of this Warrant, the prevailing party in such action, suit or proceeding shall be reimbursed by the other party for their reasonable attorneys’ fees and other costs and expenses incurred with the investigation, preparation and prosecution of such action or proceeding.

f)Restrictions. The Holder acknowledges that the Warrant Shares acquired upon the exercise of this Warrant, if not registered, and the Holder does not utilize cashless exercise, will have restrictions upon resale imposed by state and federal securities laws.

g)Nonwaiver and Expenses. No course of dealing or any delay or failure to exercise any right hereunder on the part of Holder shall operate as a waiver of such right or otherwise prejudice the Holder’s rights, powers or remedies, notwithstanding the fact that all rights hereunder terminate on the Termination Date. Without limiting any other provision of this Warrant, if the Company willfully and knowingly fails to comply with any provision of this Warrant, which results in any material damages to the Holder, the Company shall pay to the Holder such amounts as shall be sufficient to cover any costs and expenses including, but not limited to, reasonable attorneys’ fees, including those of appellate

proceedings, incurred by the Holder in collecting any amounts due pursuant hereto or in otherwise enforcing any of its rights, powers or remedies hereunder.

h)Notices. Any and all notices or other communications or deliveries to be provided by the Holders hereunder including, without limitation, any Notice of Exercise, shall be in writing and delivered personally, by facsimile or e-mail, or sent by a nationally recognized overnight courier service, addressed to the Company, at 19 Presidential Way, Woburn, Massachusetts 01801, Attention: Chief Executive Officer, email address: peoples@yield10bio.com, or such other facsimile number, email address or address as the Company may specify for such purposes by notice to the Holders. Any and all notices or other communications or deliveries to be provided by the Company hereunder shall be in writing and delivered personally, by facsimile or by e-mail, or sent by a nationally recognized overnight courier service addressed to each Holder at the facsimile number, e-mail address or address of such Holder appearing on the books of the Company. Any notice or other communication or deliveries hereunder shall be deemed given and effective on the earliest of (i) the date of transmission, if such notice or communication is delivered via facsimile at the facsimile number or via e-mail at the e-mail address set forth in this Section prior to 5:30 p.m. (New York City time) on any date, (ii) the next Trading Day after the date of transmission, if such notice or communication is delivered via facsimile at the facsimile number or via e-mail at the e-mail address set forth in this Section on a day that is not a Trading Day or later than 5:30 p.m. (New York City time) on any Trading Day, (iii) the second Trading Day following the date of mailing, if sent by U.S. nationally recognized overnight courier service, or (iv) upon actual receipt by the party to whom such notice is required to be given. To the extent that any notice provided hereunder constitutes, or contains, material, non-public information regarding the Company or any subsidiaries, the Company shall simultaneously file such notice with the Commission pursuant to a Current Report on Form 8-K.

i)Limitation of Liability. No provision hereof, in the absence of any affirmative action by the Holder to exercise this Warrant to purchase Warrant Shares, and no enumeration herein of the rights or privileges of the Holder, shall give rise to any liability of the Holder for the purchase price of any Common Stock or as a stockholder of the Company, whether such liability is asserted by the Company or by creditors of the Company.

j)Remedies. The Holder, in addition to being entitled to exercise all rights granted by law, including recovery of damages, will be entitled to specific performance of its rights under this Warrant. The Company agrees that monetary damages would not be adequate compensation for any loss incurred by reason of a breach by it of the provisions

of this Warrant and hereby agrees to waive and not to assert the defense in any action for specific performance that a remedy at law would be adequate.

k)Successors and Assigns. Subject to applicable securities laws, this Warrant and the rights and obligations evidenced hereby shall inure to the benefit of and be binding upon the successors and permitted assigns of the Company and the successors and permitted assigns of Holder. The provisions of this Warrant are intended to be for the benefit of any Holder from time to time of this Warrant and shall be enforceable by the Holder or holder of Warrant Shares.

l)Amendment. This Warrant may be modified or amended or the provisions hereof waived with the written consent of the Company, on the one hand, and the Holder or the beneficial owner of this Warrant, on the other hand. This Warrant also may be modified or amended or the provisions hereof waived with the written consent of the Company and the holders of Warrants representing 67% of the Warrant Shares issuable under Warrants then outstanding as of the date such consent is sought; provided, however, that (i) no such amendment shall adversely affect any Holder differently than it affects all other Holders, unless such Holder consents thereto and (ii) no amendment may increase the Exercise Price, decrease the number of shares or change the class of shares obtainable upon exercise of this Warrant or decrease the time period in which this Warrant can be exercised without the written consent of the Holder.

m)Severability. Wherever possible, each provision of this Warrant shall be interpreted in such manner as to be effective and valid under applicable law, but if any provision of this Warrant shall be prohibited by or invalid under applicable law, such provision shall be ineffective to the extent of such prohibition or invalidity, without invalidating the remainder of such provisions or the remaining provisions of this Warrant.

n)Headings. The headings used in this Warrant are for the convenience of reference only and shall not, for any purpose, be deemed a part of this Warrant.

o)Warrant Agency Agreement. If this Warrant is held in global form through DTC (or any successor depositary), this Warrant is issued subject to the Warrant Agency Agreement. To the extent any provision of this Warrant conflicts with the express provisions of the Warrant Agency Agreement, the provisions of this Warrant shall govern and be controlling.

SECURITIES PURCHASE AGREEMENT

This SECURITIES PURCHASE AGREEMENT (this “Agreement”) dated November __, 2019, is entered into by and among (i) Yield10 Bioscience, Inc., a Delaware corporation (the “Company”), and (ii) each person listed on Schedule I hereto (each, an “Investor” and collectively, the “Investors”).

WHEREAS, subject to the terms and conditions set forth in this Agreement, the Company desires to issue and sell to each Investor, and each Investor, severally and not jointly, desires to purchase from the Company, an aggregate of 4,600 units of the Company’s securities (each, a “Unit” and collectively, the “Units”), in a private placement pursuant to Section 4(a)(2) of the Securities Act of 1933, as amended (the “Securities Act”); and

WHEREAS, as provided in the certificate of designation, in the form of Exhibit A attached hereto (the “Certificate of Designation”), to be filed by the Company prior to the Closing (as defined below) with the Secretary of State of the State of Delaware, each share of Preferred Stock will automatically convert into one share of Common Stock upon the effectiveness of the filing with the Secretary of State of the State of Delaware of an amendment (the “Charter Amendment”) to the Company’s Restated Certificate of Incorporation, as amended, increasing the number of authorized shares of Common Stock to a number to be determined in consultation with the Investors.

NOW THEREFORE, in consideration of the mutual covenants made herein and for other good and valuable consideration, the receipt and sufficiency of which are hereby acknowledged, the parties hereto, intending to be legally bound, agree as follows:

1.Purchase and Sale of Securities. Subject to the terms and conditions hereof, each Investor agrees, severally and not jointly, to purchase from the Company, and the Company agrees to sell to the Investors at the Closing, the number of Units set forth opposite each such Investor’s name on Schedule I hereto for the aggregate purchase price set forth in Schedule I hereto. Each Unit will consist of one share of our Series B Preferred Stock, par value $0.01 per share (the “Series B Preferred Stock”) convertible into 2,777 shares of common stock, Series A Warrants to purchase 2,777 shares of common stock and Series B Warrants to purchase 2,777 shares of common stock, at a price of $1,000 per Unit.

2. Issuance of Securities. Notwithstanding anything in this Agreement to the contrary, the Company shall have no obligation to sell any of the Securities (as defined below) to any person who is a resident of a jurisdiction in which the sale of Securities to such person would constitute a violation of the securities, “blue sky” or other similar laws of such jurisdiction (collectively referred to as the “State Securities Laws”). For purposes of this Agreement, “Securities” shall mean the shares of Series B Preferred Stock (the “Preferred Shares”) and the

shares of Common Stock issued or issuable upon conversion of the Preferred Shares, the Series A Warrants and the Series B Warrants (such shares of Common Stock, the “Underlying Shares”).

3. The Closing. The closing of the purchase and sale of the Units (the “Closing”) shall take place at the headquarters of the Company as promptly as practicable after the satisfaction or waiver (to the extent permitted by law) of the conditions set forth in Section 7 hereof, or at such other time and place as the Company may designate by notice to the Investors (such date and time being referred to herein as the “Closing Date”); provided, however, that if the Closing Date does not occur on or before February 1, 2020, this Agreement may be terminated by any Investor, as to such Investor’s obligations hereunder and without any effect whatsoever on the obligations between the Company and the other Investors, by written notice to the other parties.

4. Payment for Securities. Payment for the Units shall be received by the Company from the Investors by wire transfer of immediately available funds or other means approved by the Company at or prior to the Closing, at the price of $1,000.00 per Unit. The Company shall deliver or cause its transfer agent to deliver certificates representing the Preferred Shares, the Series A Warrants and the Series B Warrants, that each Investor purchases to each such Investor at the Closing bearing the legend set forth in Section 10.

5. Representations and Warranties of the Company.

Designation and this Agreement, will be validly issued, fully paid and non-assessable and shall be free and clear of any encumbrances, preemptive rights or restrictions (other than as provided in this Agreement or any restrictions on transfer generally imposed under applicable securities laws).

There is no action, suit, proceeding or investigation pending or, to the Company’s knowledge, currently threatened in writing against the Company or any subsidiary or any of their respective directors and officers which would have, either individually or in the aggregate, a Material Adverse Effect (as defined below).

(g) Filings. The Company has filed all forms, reports and documents required to be filed by it with the Commission (collectively, the “Company SEC Reports”). As of the respective dates they were filed (except if amended, updated or superseded by a filing made by

The Company has not had any material disagreement with any of its auditors regarding accounting matters or policies during any of its past three full fiscal years or during the current fiscal year-to-date, which disagreements would require disclosure to the Company’s Board of Directors.

(i) Certain Fees.

(j) Acknowledgment Regarding Investors’ Purchase of Securities. The Company acknowledges and agrees that each of the Investors is acting solely in the capacity of an arm’s length purchaser with respect to this Agreement and the transactions contemplated hereby. The Company further acknowledges that no Investor is acting as a financial advisor or fiduciary of the Company (or in any similar capacity) with respect to this Agreement and the transactions contemplated hereby and any advice given by any Investor or any of their respective representatives or agents in connection with this Agreement and the transactions contemplated hereby is merely incidental to the Investors’ purchase of the Securities. The Company further represents to each Investor that the Company’s decision to enter into this Agreement has been

based solely on the independent evaluation of the transactions contemplated hereby by the Company and its representatives.

(k) Acknowledgment Regarding Investors’ Trading Activity. Anything in this Agreement or elsewhere herein to the contrary notwithstanding (except for Sections 6(a)(iv) and 12 hereof), it is understood and acknowledged by the Company that: (i) none of the Investors has been asked by the Company to agree, nor has any Investor agreed, to desist from purchasing or selling, long and/or short, securities of the Company, or “derivative” securities based on securities issued by the Company or to hold the Securities for any specified term, (ii) past or future open market or other transactions by any Investor, specifically including, without limitation, short sales or “derivative” transactions, before or after the Closing, may negatively impact the market price of the Company’s publicly-traded securities, (iii) any Investor, and counter-parties in “derivative” transactions to which any such Investor is a party, directly or indirectly, may presently have a “short” position in the Common Stock and (iv) each Investor shall not be deemed to have any affiliation with or control over any arm’s length counter-party in any “derivative” transaction. The Company further understands and acknowledges that, except as otherwise provided by applicable law or the policies of the Company applicable to directors, officers and employees of the Company, (y) one or more Investors may engage in hedging activities at various times during the period that the Securities are outstanding, including, without limitation, during the periods that the value of the Underlying Shares deliverable with respect to Securities are being determined, and (z) such hedging activities (if any) could reduce the value of the existing stockholders’ equity interests in the Company at and after the time that the hedging activities are being conducted. The Company acknowledges that such aforementioned hedging activities do not constitute a breach of this Agreement.

6. Representations and Warranties of the Investors. As of the date hereof and as of the Closing, each of the Investors, severally and not jointly, hereby represents and warrants to and covenants with the Company that:

(a) General.

(i) The Investor has all requisite authority to purchase the Securities, enter into this Agreement and to perform all the obligations required to be performed by the Investor hereunder, and such purchase will not contravene any law, rule or regulation binding on the Investor or any investment guideline or restriction applicable to the Investor.

(ii) The Investor is acquiring the Securities for its own account and is not acquiring the Securities as a nominee or agent or otherwise for any other person.

(iii) The Investor will comply with all applicable laws and regulations the Investor is required to comply with in connection with the purchase or sale of Securities in

(iv) Other than consummating the transactions contemplated hereby, the Investor has not directly or indirectly, nor has any person acting on behalf of or pursuant to any understanding with such Investor, executed any purchases or sales, including short sales, of the securities of the Company during the period commencing as of the time that such Investor first received a term sheet (written or oral) from the Company or any other person representing the Company setting forth the material terms of the transactions contemplated hereby and ending immediately prior to the execution hereof. Notwithstanding the foregoing, in the case of an Investor that is a multi-managed investment vehicle whereby separate portfolio managers manage separate portions of such Investor’s assets and the portfolio managers have no direct knowledge of the investment decisions made by the portfolio managers managing other portions of such Investor’s assets, the representation set forth above shall only apply with respect to the portion of assets managed by the portfolio manager that made the investment decision to purchase the Securities covered by this Agreement. Other than to other persons party to this Agreement, such Investor has maintained the confidentiality of all disclosures made to it in connection with this transaction (including the existence and terms of this transaction). Notwithstanding the foregoing, for avoidance of doubt, nothing contained herein shall constitute a representation or warranty, or preclude any actions, with respect to the identification of the availability of, or securing of, available shares to borrow in order to effect short sales or similar transactions in the future.

(b) Information Concerning the Company.

(i) The Investor understands and accepts that the purchase of the Securities involves various risks. The Investor represents that it is able to bear a complete loss of its investment in the Securities.

(ii) The Investor confirms that it is not relying on any communication (written or oral) of the Company or any of its affiliates, as investment advice or as a recommendation to purchase the Securities.

The Investor acknowledges that neither the Company nor any of its affiliates has made any representation regarding the proper

characterization of the Securities for purposes of determining the Investor’s authority to invest in the Securities.

(iii) The Investor acknowledges that it has had the opportunity to review this Agreement (including all exhibits and schedules hereto) and the Disclosure Package and has been afforded (A) the opportunity to ask such questions as it has deemed necessary of, and to receive answers from, representatives of the Company concerning the terms and conditions of the offering of the Securities and the merits and risks of investing in the Securities; (B) access to information about the Company and its financial condition, results of operations, business, properties, management and prospects sufficient to enable it to evaluate its investment; and (C) the opportunity to obtain such additional information that the Company possesses or can acquire without unreasonable effort or expense that is necessary to make an informed investment decision with respect to the investment.

(iv) The Investor understands that, unless the Investor notifies the Company in writing to the contrary at or before the Closing, each of the Investor’s representations and warranties contained in this Agreement will be deemed to have been reaffirmed and confirmed as of the Closing, taking into account all information received by the Investor.

(v) The Investor understands that no federal or state agency has passed upon the merits or risks of an investment in the Securities or made any finding or determination concerning the fairness or advisability of this investment.

(i) The Investor represents that it is not relying on (and will not at any time rely on) any communication (written or oral) of the Company, as investment advice or as a recommendation to purchase the Securities, it being understood that information and explanations related to the terms and conditions of the Securities shall not be considered investment advice or a recommendation to purchase the Securities.

(ii) Except as expressly provided herein, the Investor confirms that the Company has not (A) given any guarantee or representation as to the potential success, return, effect or benefit (either legal, regulatory, tax, financial, accounting or otherwise) an of investment in the Securities or (B) made any representation to the Investor regarding the legality

of an investment in the Securities under applicable legal investment or similar laws or regulations. In deciding to purchase the Securities, the Investor is not relying on the advice or recommendations of the Company and the Investor has made its own independent decision that the investment in the Securities is suitable and appropriate for the Investor.

(d) Status of Investor.

(i) The Investor has such knowledge, sophistication, skill and experience in business, financial and investment matters that the Investor is capable of evaluating the merits and risks of an investment in the Securities, and has so evaluated the merits and risks of such investment. With the assistance of the Investor’s own professional advisors, to the extent that the Investor has deemed appropriate, the Investor has made its own legal, tax, accounting and financial evaluation of the merits and risks of an investment in the Securities and the consequences of this Agreement. The Investor has considered the suitability of the Securities as an investment in light of its own circumstances and financial condition and the Investor is able to bear the risks associated with an investment in the Securities and its authority to invest in the Securities.

(ii) At the time the Investor was offered the Securities, the Investor was, and as of the date hereof the Investor is, and on the Closing Date, the Investor will be either (A) a “qualified institutional buyer” as defined in Rule 144A(a) under the Securities Act or (B) an “accredited investor” as defined in as defined in Rule 501(a)(1), (a)(2), (a)(3), (a)(7), or (a)(8) under the Securities Act, and not required to be registered as a broker-dealer under Section 15 of the Exchange Act.

(e) Restrictions on Transfer or Sale of Securities.

(i) The Investor is acquiring the Securities solely for the Investor’s own beneficial account, for investment purposes, and not with a view to, or for resale in connection with, any distribution of the Securities, has no present intention of distributing any of such Securities in violation of the Securities Act or any applicable State Securities Laws and has no direct or indirect arrangement or understandings with any other persons to distribute or regarding the distribution of such Securities in violation of the Securities Act or any applicable State Securities Laws (this representation and warranty not limiting such Investor’s right to sell

the Securities pursuant to the Registration Statement (as defined below) or otherwise in compliance with applicable federal law and State Securities Laws). The Investor understands that the Securities have not been registered under the Securities Act or any State Securities Laws by reason of specific exemptions under the provisions thereof which depend in part upon the investment intent of the Investor and of the other representations made by the Investor in this Agreement. The Investor understands that the Company is relying upon the representations and agreements contained in this Agreement for the purpose of determining whether this transaction meets the requirements for such exemptions.

(ii) The Investor understands that the Securities are “restricted securities” under applicable federal securities laws and that the Securities Act and the rules of the Commission provide in substance that the Investor may dispose of the Securities only pursuant to an effective registration statement under the Securities Act or an exemption therefrom such as the exemption and safe harbor provided under Rule 144 of the Securities Act.

(iii) The Investor agrees that the Investor will not sell, assign, pledge, give, transfer or otherwise dispose of the Securities or any interest therein, or make any offer or attempt to do any of the foregoing, except pursuant to a registration of the Securities under the Securities Act or in a transaction which is exempt from the registration provisions of the Securities Act such as the exemption and safe harbor provided under Rule 144 of the Securities Act; that the certificates representing the Securities will bear a legend making reference to the foregoing restrictions; and that the Company and its affiliates and transfer agent shall not be required to give effect to any purported transfer of such Securities except upon compliance with the foregoing restrictions. The Company acknowledges and agrees that an Investor may from time to time pledge pursuant to a bona fide margin agreement with a registered broker-dealer or grant a security interest in some or all of the Securities to a financial institution that is an “accredited investor” as defined in Rule 501(a) under the Securities Act and who agrees to be bound by the provisions of this Agreement and, if required under the terms of such arrangement, such Purchaser may transfer pledged or secured Securities to the pledgees or secured parties. Such a pledge or transfer would not be subject to approval of the Company and no legal opinion of legal counsel of the pledgee, secured party or pledgor shall be required in connection therewith. Further, no notice shall be required of such pledge.

(i) At the request of the holders of at least a majority of the Registrable Shares (the “Majority Investors”), the Company shall use commercially reasonable efforts to file no later than 15 business days after the Stockholder Approval Date (the “Filing

Date”) a registration statement covering the resale of the Common Shares and the Underlying Shares (the “Registrable Shares”) with the Commission for an offering to be made on a continuous basis pursuant to Rule 415, or if Rule 415 is not available for offers and sales of the Registrable Shares, by such other means of distribution of Registrable Shares as the Majority Investors may reasonably specify (the “Initial Registration Statement”). The Initial Registration Statement shall be on Form S-3 (except if the Company is ineligible to register for resale the Registrable Shares on Form S-3, in which case such registration shall be on another appropriate form).

(ii) The Company shall use commercially reasonable efforts to effect the registration (including a declaration of effectiveness thereof by the Commission) and applicable qualifications or compliances (including, without limitation, the execution of any required undertaking to file post-effective amendments, appropriate qualifications or exemptions under applicable State Securities Laws and appropriate compliance with applicable securities laws, requirements or regulations) as promptly as practicable after the filing of the Initial Registration Statement, but in any event prior to the date which is 90 days after the Filing Date (the “Effectiveness Date”). The Company shall, within two (2) business days after the Effectiveness Date, file a final prospectus with the Commission as required by Rule 424 under the Securities Act.

(iii) In the event that all of the Registrable Shares cannot, as a result of the rules and regulations of the Commission, be registered for resale as a secondary offering on a single registration statement, the Company agrees to promptly (i) inform the Investors thereof, (ii) use commercially reasonable efforts to file amendments to the Initial Registration Statement as required by the Commission and/or (iii) withdraw the Initial Registration Statement and use commercially reasonable efforts to file a new registration statement (a “New Registration Statement”), in either case covering the maximum number of Registrable Shares permitted to be registered by the Commission, on Form S-3 or, if the Company is ineligible to register for resale the Registrable Shares on Form S-3, such other form available to register for resale the Registrable Shares as a secondary offering; provided, however, that prior to filing such amendment or New Registration Statement, the Company shall be obligated to use commercially reasonable efforts to advocate with the Commission for the registration of all of the Registrable Shares. In the event the Company amends the Initial Registration Statement or files a New Registration Statement, as the case may be, under clauses (ii) or (iii) above, the Company will use commercially reasonable efforts to file with the Commission, as promptly as practicable, one or more registration statements on Form S-3 or, if the Company is ineligible to register for resale the Registrable Shares on Form S-3, such other form available to register for resale those Registrable Shares that were not registered for resale on the Initial Registration Statement, as amended, or the New Registration Statement (the “Remainder Registration Statements” and,

collectively with the Initial Registration Statement and the New Registration Statement, the “Registration Statements”).

(iv) Notwithstanding any other provision of this Agreement, if the Commission limits the number of Registrable Shares permitted to be registered on a particular Registration Statement (and notwithstanding that the Company used diligent efforts to advocate with the Commission for the registration of all or a greater number of Registrable Shares), unless otherwise directed in writing by a Holder as to its Registrable Shares, the number of Registrable Shares to be registered on such Registration Statement will be reduced as follows:


(1)	First, the Company shall reduce or eliminate any securities to be included other than Registrable Shares;


(2)	Second, the Company shall reduce Registrable Shares (applied to the Investors on a pro rata basis based on the total number of unregistered Registrable Shares held by such Investors).

In the event of a cutback hereunder, the Company shall give the Investors at least three (3) business days prior written notice along with the calculations as to such Investor’s allotment.

(b) All expenses incurred by the Company in complying with Section 9(a) hereof, including, without limitation, all registration, qualification and filing fees, printing expenses, escrow fees, fees and expenses of counsel for the Company, blue sky fees and expenses and the expense of any special audits incident to or required by any such registration (but excluding the fees of legal counsel for any Investor or holder of Registrable Shares) shall be borne by the Company. All selling commissions applicable to the sale of Registrable Shares and all fees and expenses of legal counsel for any Investor or holder of Registrable Shares related to the registration and sale of the Registrable Shares shall be borne by the Investor or holder of Registrable Shares incurring such commissions, fees or expenses.

(c) In the case of the registration, qualification, exemption or compliance effected by the Company pursuant to this Agreement, the Company shall, upon reasonable request, inform the Investors as to the status of such registration, qualification, exemption and compliance. At its expense the Company shall:

(i) except for such times as the Company is permitted hereunder to suspend the use of the prospectus forming part of a Registration Statement, use its commercially reasonable efforts to keep such registration, and any qualification, exemption or compliance under State Securities Laws which the Company determines to obtain, continuously effective with respect to the Investors, and to keep the applicable Registration Statement effective until the later of (A) two (2) years from the Closing Date, (B) the date by which all the Registrable Shares

may be sold without volume or manner of sale restrictions which may be applicable to affiliates under Rule 144, or (C) the date on which all of the Registrable Shares are sold. The period of time during which the Company is required hereunder to keep a Registration Statement effective is referred to herein as the “Registration Period”;

(ii) advise the Investors within five (5) business days:


(1)	when a Registration Statement or any amendment thereto has been filed with the Commission and when such Registration Statement or any post-effective amendment thereto has become effective;


(2)	of any request by the Commission for amendments or supplements to any Registration Statement or the prospectus included therein or for additional information;


(3)	of the issuance by the Commission of any stop order suspending the effectiveness of any Registration Statement or, to the Company’s knowledge, the initiation of any proceedings for such purpose;


(4)	of the receipt by the Company of any notification with respect to the suspension of the qualification of the Registrable Shares included therein for sale in any jurisdiction or, to the Company’s knowledge, the initiation or threatening of any proceeding for such purpose; and

(5)

subject to the provisions this Agreement, of the occurrence of any event that requires the making of any changes in any Registration Statement or prospectus so that, as of such date, the statements therein are not misleading and do not omit to state a material fact required to be stated therein or necessary to make the statements therein (in the case of a prospectus, in the light of the circumstances under which they were made) not misleading;

(iii) use its commercially reasonable efforts to obtain the withdrawal of any order suspending the effectiveness of any Registration Statement as soon as reasonably practicable;

(iv) if an Investor so requests in writing, promptly furnish to the Investor, without charge, at least one copy of each Registration Statement and each post-effective

amendment thereto, including financial statements and schedules, and, if explicitly requested, all exhibits in the form filed with the Commission;

(v) during the Registration Period, promptly deliver to each Investor, without charge, as many copies of each prospectus included in a Registration Statement and any amendment or supplement thereto as the Investor may reasonably request in writing; and the Company consents to the use, consistent with the provisions hereof, of the prospectus or any amendment or supplement thereto by the Investor of Registrable Shares in connection with the offering and sale of the Registrable Shares covered by a prospectus or any amendment or supplement thereto;

(vi) during the Registration Period, if an Investor so requests in writing, deliver to the Investor, without charge, (i) one copy of the following documents, other than those documents available via the Commission’s EDGAR system: (A) its annual report on Form 10-K (or similar form), (B) its definitive proxy statement with respect to its annual meeting of stockholders, (C) each of its quarterly reports on Form 10-Q, and (D) a copy of each full Registration Statement (the foregoing, in each case, excluding exhibits); and (ii) if explicitly requested, all exhibits excluded by the parenthetical to the immediately preceding clause (D); provided, that the Company shall have no obligation to provide any document pursuant to this clause that is available on the Commission’s EDGAR system;

(vii) prior to any public offering of Registrable Shares pursuant to any Registration Statement, promptly take such actions as may be necessary to register or qualify or obtain an exemption for offer and sale under State Securities Laws of such United States jurisdictions as an Investor reasonably request in writing; provided that the Company shall not for any such purpose be required to qualify generally to transact business as a foreign corporation in any jurisdiction where it is not so qualified or to consent to general service of process in any such jurisdiction, and do any and all other acts or things reasonably necessary or advisable to enable the offer and sale in such jurisdictions of the Registrable Shares covered by any such Registration Statement;

(viii) upon the occurrence of any event contemplated by Section 9(c)(ii)(5) above, except for such times as the Company is permitted hereunder to suspend the use of a prospectus forming part of a Registration Statement, and taking into account the Company’s good faith assessment of any adverse consequences to the Company and its stockholders of the premature disclosure of such event, the Company shall use its commercially reasonable efforts to prepare a post-effective amendment to such Registration Statement or a supplement to the related prospectus, or file any other required document so that, as thereafter delivered to purchasers of the Registrable Shares included therein, such prospectus will not include any untrue statement of

a material fact or omit to state any material fact necessary to make the statements therein, in the light of the circumstances under which they were made, not misleading;

(ix) otherwise use its commercially reasonable efforts to comply in all material respects with all applicable rules and regulations of the Commission which could affect the sale of the Registrable Shares;

(x) use its commercially reasonable efforts to cause all Registrable Shares to be listed on each securities exchange or market, if any, on which equity securities issued by the Company have been listed; and

(xi) cooperate with any broker-dealer through which an Investor proposes to resell its Registrable Shares in such broker-dealer’s filing with the FINRA Corporate Financing Department pursuant to FINRA Rule 5110, as requested by any such Investor.

(d) No Investor shall have the right to take any action to restrain, enjoin or otherwise delay any registration pursuant to Section 9(a) hereof as a result of any controversy that may arise with respect to the interpretation or implementation of this Agreement.

(e) Indemnification.

(i) To the extent permitted by law, the Company shall indemnify each Investor and each person controlling such Investor within the meaning of Section 15 of the Securities Act, with respect to which any registration that has been effected pursuant to this Agreement, against all claims, losses, damages and liabilities (or action in respect thereof), including any of the foregoing incurred in settlement of any litigation, commenced or threatened (subject to Section 9(e)(iii) below), arising out of or based on any untrue statement (or alleged untrue statement) of a material fact contained in any Registration Statement, prospectus, any amendment or supplement thereof, or other document incident to any registration, qualification or compliance or based on any omission (or alleged omission) to state therein a material fact required to be stated therein or necessary to make the statements therein not misleading, in light of the circumstances in which they were made, or any violation by the Company of any rule or regulation promulgated by the Securities Act applicable to the Company and relating to any action or inaction required of the Company in connection with any such registration, qualification or compliance, and will reimburse each Investor and each person controlling such Investor, for reasonable legal and other out-of-pocket expenses reasonably incurred in connection with investigating or defending any such claim, loss, damage, liability or action as incurred; provided that the Company will not be liable in any such case to the extent that any untrue statement or omission or allegation thereof is made in reliance upon and in conformity with written information furnished to the Company by or on behalf of such Investor for use in preparation of any Registration Statement, prospectus, amendment or supplement; provided

however, that the Company will not be liable in any such case where the claim, loss, damage or liability arises out of the failure of such Investor to comply with the covenants and agreements contained in this Agreement respecting sales of Registrable Shares, and except that the foregoing indemnity agreement is subject to the condition that, insofar as it relates to any such untrue statement or alleged untrue statement or omission or alleged omission made in any preliminary prospectus but eliminated or remedied in the amended prospectus on file with the Commission at the time any Registration Statement becomes effective or in an amended prospectus filed with the Commission pursuant to Rule 424(b) which meets the requirements of Section 10(a) of the Securities Act (each, a “Final Prospectus”), such indemnity shall not inure to the benefit of the Investor or any such controlling person, if a copy of a Final Prospectus furnished by the Company to the Investor for delivery was not furnished to the person or entity asserting the loss, liability, claim or damage at or prior to the time such furnishing is required by the Securities Act and a Final Prospectus would have cured the defect giving rise to such loss, liability, claim or damage.

(ii) Each Investor will, severally and not jointly, indemnify the Company, each of its directors and officers, and each person who controls the Company within the meaning of Section 15 of the Securities Act, against all claims, losses, damages and liabilities (or actions in respect thereof), including any of the foregoing incurred in settlement of any litigation, commenced or threatened (subject to Section 9(e)(iii) below), arising out of or based on any untrue statement (or alleged untrue statement) of a material fact contained in any Registration Statement, prospectus, any amendment or supplement thereof, or other document incident to any such registration, or based on any omission (or alleged omission) to state therein a material fact required to be stated therein or necessary to make the statements therein not misleading, in light of the circumstances in which they were made, and will reimburse the Company, such directors and officers, and each person controlling the Company for reasonable legal and any other expenses reasonably incurred in connection with investigating or defending any such claim, loss, damage, liability or action as incurred, in each case to the extent, but only to the extent, that such untrue statement or omission or allegation thereof is made in reliance upon and in conformity with written information furnished to the Company by or on behalf of such Investor for use in preparation of any Registration Statement, prospectus, amendment or supplement. Notwithstanding the foregoing, the maximum liability of the Investor under this section shall be limited to the proceeds received by the Investor from the sale of Registrable Shares.

(iii) Each party entitled to indemnification under this Section 9(e) (the “Indemnified Party”) shall give notice to the party required to provide indemnification (the “Indemnifying Party”) promptly after such Indemnified Party has actual knowledge of any claim as to which indemnity may be sought, and shall permit the Indemnifying Party (at its expense) to assume the defense of any such claim or any litigation resulting therefrom, provided that counsel

for the Indemnifying Party, who shall conduct the defense of such claim or litigation, shall be approved by the Indemnified Party (whose approval shall not unreasonably be withheld, conditioned or delayed), and the Indemnified Party may participate in such defense at such Indemnified Party’s expense, and provided further that the failure of any Indemnified Party to give notice as provided herein shall not relieve the Indemnifying Party of its obligations under this Agreement, unless such failure is materially prejudicial to the Indemnifying Party in defending such claim or litigation. An Indemnifying Party shall not be liable for any settlement of an action or claim effected without its written consent (which consent shall not be unreasonably withheld, conditioned or delayed). No Indemnifying Party, in its defense of any such claim or litigation, shall, except with the consent of each Indemnified Party (which consent shall not be unreasonably withheld, conditioned or delayed), consent to entry of any judgment or enter into any settlement which does not include as an unconditional term thereof the giving by the claimant or plaintiff to such Indemnified Party of a release from all liability in respect to such claim or litigation.

(iv) If the indemnification provided for in this Section 9(e) is held by a court of competent jurisdiction to be unavailable to an Indemnified Party with respect to any loss, liability, claim, damage or expense referred to therein, then the Indemnifying Party, in lieu of indemnifying such Indemnified Party thereunder, shall contribute to the amount paid or payable by such Indemnified Party as a result of such loss, liability, claim, damage or expense in such proportion as is appropriate to reflect the relative fault of the Indemnifying Party on the one hand and of the Indemnified Party on the other in connection with the statements or omissions which resulted in such loss, liability, claim, damage or expense as well as any other relevant equitable considerations. The relative fault of the Indemnifying Party and of the Indemnified Party shall be determined by reference to, among other things, whether the untrue or alleged untrue statement of a material fact or the omission to state a material fact relates to information supplied by the Indemnifying Party or by the Indemnified Party and the parties’ relative intent, knowledge, access to information and opportunity to correct or prevent such statement or omission. The parties hereto agree that it would not be just and equitable if contribution pursuant to this Section 9(e) were determined by pro rata allocation or by any other method of allocation that does not take into account the equitable considerations referred to in the immediately preceding paragraph. Notwithstanding the provisions of this Section 9(e), no Investor shall be required to contribute pursuant to this Section 9(e), in the aggregate, any amount in excess of the amount by which the net proceeds actually received by such Investor from the sale of the Registrable Shares exceeds the amount of any damages that such Investor has otherwise been required to pay by reason of such untrue or alleged untrue statement or omission or alleged omission.

(f) Disclosure, Etc.

(i) Not less than five (5) business days prior to the filing of each Registration Statement, the Company shall furnish to each Investor copies of such Registration Statement and all exhibits being filed therewith, and shall consider in good faith the reasonable comments of such Investor. Notwithstanding the foregoing sentence, the Company shall not be obligated to provide the Investors advance copies of any universal shelf registration statement registering securities in addition to those required hereunder. Each Investor agrees that, upon receipt of any notice from the Company of the happening of any event requiring the preparation of a supplement or amendment to a prospectus relating to Registrable Shares so that, as thereafter delivered to the Investor, such prospectus shall not contain an untrue statement of a material fact or omit to state any material fact required to be stated therein or necessary to make the statements therein not misleading, the Investor will forthwith discontinue disposition of Registrable Shares pursuant to a Registration Statement and prospectus contemplated by Section 9(a) until its receipt of copies of the supplemented or amended prospectus from the Company and, if so directed by the Company, the Investor shall deliver to the Company all copies, other than permanent file copies then in the Investor’s possession, of the prospectus covering such Registrable Shares current at the time of receipt of such notice.

(ii) Each Investor shall suspend, upon request of the Company, any disposition of Registrable Shares pursuant to any Registration Statement and prospectus contemplated by Section 9(a) during the occurrence or existence of any pending corporate development with respect to the Company that the Board of Directors of the Company believes in good faith may be material and that, in the determination of the Board of Directors of the Company, makes it not in the best interest of the Company to allow continued availability of a Registration Statement or prospectus. The Company shall be entitled to exercise its right under this paragraph to suspend the availability of a Registration Statement and prospectus for a period not to exceed 60 calendar days (which need not be consecutive days) in any 12-month period.

(iii) Upon the occurrence of any event contemplated by Section 3(d), as promptly as reasonably possible under the circumstances taking into account the Company’s good faith assessment of any adverse consequences to the Company and its stockholders of the premature disclosure of such event, prepare a supplement or amendment, including a post-effective amendment, to a Registration Statement or a supplement to the related prospectus or any document incorporated or deemed to be incorporated therein by reference, and file any other required document so that, as thereafter delivered, neither a Registration Statement nor such prospectus will contain an untrue statement of a material fact or omit to state a material fact required to be stated therein or necessary to make the statements therein, in light of the circumstances under which they were made, not misleading. The Company will use its best efforts to ensure that the use of the prospectus may be resumed as promptly as is practicable. The Company shall be entitled to exercise its right under this Section 9(f) to suspend the

availability of a Registration Statement and prospectus for a period not to exceed 60 calendar days (which need not be consecutive days) in any 12-month period.

(iv) As a condition to the inclusion of its Registrable Shares, the Investor shall furnish to the Company such information regarding the Investor and the distribution proposed by the Investor as the Company may reasonably request in writing, including completing a Registration Statement Questionnaire in the form provided by the Company, or as shall be required in connection with any registration referred to in this Section 9.

(v) Each Investor hereby covenants with the Company (i) not to make any sale of the Registrable Shares without effectively causing the prospectus delivery requirements under the Securities Act to be satisfied (unless such sale is pursuant to Rule 144).

(vi) Each Investor agrees not to take any action with respect to any distribution deemed to be made pursuant to a Registration Statement which would constitute a violation of Regulation M under the Exchange Act or any other applicable rule, regulation or law.

(vii) At the end of the Registration Period, each Investor shall discontinue sales of shares pursuant to any Registration Statement upon receipt of notice from the Company of its intention to remove from registration the shares covered by any such Registration Statement which remain unsold, and the Investor shall notify the Company of the number of shares registered which remain unsold immediately upon receipt of such notice from the Company.

(g) The rights to cause the Company to register Registrable Shares granted to the Investors by the Company under Section 9(a) may be assigned by an Investor in connection with a transfer by such Investor of all or a portion of its Registrable Shares, provided, however, that the Investor must give the Company at least 10 days prior notice of such transfer for such transfer to be reflected in the Registration Statement or any amendment thereto and that (i) such transfer may otherwise be effected in accordance with applicable securities laws; (ii) such Investor gives prior written notice to the Company at least 10 days prior to the transfer; and (iii) such transferee agrees to comply with the terms and provisions of this Agreement, and such transfer is otherwise in compliance with this Agreement. Except as specifically permitted by this Section 9(g), the rights of an Investor with respect to Registrable Shares as set out herein shall not be transferable to any other person, and any attempted transfer shall cause all rights of such Investor therein to be forfeited.

(h) The rights of an Investor under any provision of this Section 9 may be waived (either generally or in a particular instance, either retroactively or prospectively and

either for a specified period of time or indefinitely) or amended by an instrument in writing signed by such Investor.

10. Legend. At the Closing, the certificates representing the Preferred Shares sold pursuant to this Agreement, and upon issuance the certificates representing the Underlying Shares, will be imprinted with a legend in substantially the following form:

THIS SECURITY HAS NOT BEEN REGISTERED WITH THE SECURITIES AND EXCHANGE COMMISSION OR THE SECURITIES COMMISSION OF ANY STATE IN RELIANCE UPON AN EXEMPTION FROM REGISTRATION UNDER THE SECURITIES ACT OF 1933, AS AMENDED (THE “SECURITIES ACT”), AND, ACCORDINGLY, MAY NOT BE OFFERED OR SOLD EXCEPT PURSUANT TO AN EFFECTIVE REGISTRATION STATEMENT UNDER THE SECURITIES ACT OR PURSUANT TO AN AVAILABLE EXEMPTION FROM, OR IN A TRANSACTION NOT SUBJECT TO, THE REGISTRATION REQUIREMENTS OF THE SECURITIES ACT AND IN ACCORDANCE WITH APPLICABLE STATE SECURITIES LAWS AS EVIDENCED BY A LEGAL OPINION OF COUNSEL TO THE TRANSFEROR TO SUCH EFFECT, THE SUBSTANCE OF WHICH SHALL BE REASONABLY ACCEPTABLE TO THE COMPANY. THIS SECURITY MAY BE PLEDGED IN CONNECTION WITH A BONA FIDE MARGIN ACCOUNT WITH A REGISTERED BROKER-DEALER OR OTHER LOAN WITH A FINANCIAL INSTITUTION THAT IS AN “ACCREDITED INVESTOR” AS DEFINED IN RULE 501(a) UNDER THE SECURITIES ACT OR OTHER LOAN SECURED BY SUCH SECURITIES.

provided, that the Company shall (a) cause such legend to be promptly removed once a registration statement covering the resale of any Securities is effective under the Securities Act or if such legend is no longer required under applicable law and (b) in connection with any sale under Rule 144, promptly (and in any event within five (5) business days after receipt by the Company of a request therefor accompanied by all reasonably required documentation) deliver, or cause to be delivered, to the Investors new certificate(s) representing such Securities that are free from all restrictive and other legends or, at the request of an Investor, via DWAC transfer to such Investor’s account.

11. Replacement of Securities. If any certificate or instrument evidencing any Securities is mutilated, lost, stolen or destroyed, the Company shall issue or cause to be issued in exchange and substitution for and upon cancellation thereof (in the case of mutilation), or in lieu of and substitution therefor, a new certificate or instrument, but only upon receipt of evidence reasonably satisfactory to the Company of such loss, theft or destruction. The applicant for a new certificate or instrument under such circumstances shall also pay any reasonable third-party costs (including customary indemnity) associated with the issuance of such replacement Securities.

12. Certain Transactions. Each Investor, severally and not jointly, covenants that neither it, nor any affiliate acting on its behalf or pursuant to any understanding with it will execute any purchases or sales, including short sales, of any of the Company’s securities during the period commencing with the execution of this Agreement and ending at such time that the transactions contemplated by this Agreement are first publicly announced pursuant to the initial press release as described in Section 8(b).

13. Expenses. The parties hereto shall pay their own costs and expenses in connection herewith; provided that, subject to the consummation of the transactions contemplated hereby, the Company shall reimburse the Investors upon demand for up to $50,000 of reasonable out-of-pocket expenses incurred by the Investors, including without limitation reimbursement of reasonable attorneys’ fees, in connection with the negotiation and execution of this Agreement and the consummation of the transactions contemplated hereby.

14. Waiver, Amendment. Neither this Agreement nor any provisions hereof shall be amended, waived, discharged or terminated except by an instrument in writing signed, in the case of an amendment, by the Company and Investors holding not less than a majority of the Registrable Shares affected by such amendment or, in the case of a waiver, discharge or termination, by the party against whom such waiver, discharge or termination is sought.

15. Assignability. This Agreement shall be binding upon and inure to the benefit of the parties and their successors and permitted assigns. The Company may not assign this Agreement or any rights or obligations hereunder without the prior written consent of the Investors holding not less than a majority of the Registrable Shares. Any Investor may assign any or all of its rights under this Agreement to any person to whom such Investor assigns or transfers any Securities; provided that such transferee agrees in writing to be bound, with respect to the transferred Securities, by the provisions of this Agreement that apply to the “Investors.” Additionally, at any time prior to the Closing, any Investor may allocate any portion of his, her or its Units being purchased hereunder to a third party reasonably acceptable to the Company (an “Additional Investor”), provided that such Additional Investor executes a counterpart signature page to this Agreement becoming an Investor hereunder in all respects, including without limitation making the representations and warranties in Section 6 of this Agreement. In the event an Additional Investor becomes a party to this Agreement, Schedule I to this Agreement shall be updated automatically without the need for an amendment to this Agreement.

16. Waiver of Jury Trial. EACH OF THE COMPANY AND THE INVESTORS IRREVOCABLY WAIVES ANY AND ALL RIGHT TO TRIAL BY JURY WITH RESPECT TO ANY LEGAL PROCEEDING ARISING OUT OF THE TRANSACTIONS CONTEMPLATED BY THIS AGREEMENT.

17. Submission to Jurisdiction. With respect to any suit, action or proceeding relating to any offers, purchases or sales of the Securities by the Investors (“Proceedings”), each of the Company and the Investors irrevocably submits to the jurisdiction of the federal or state courts located in the State of Delaware, which submission shall be exclusive unless none of such courts has lawful jurisdiction over such Proceedings.

18. Governing Law. This Agreement shall be governed by and construed in accordance with the laws of the State of Delaware.

19. Section and Other Headings. The section and other headings contained in this Agreement are for reference purposes only and shall not affect the meaning or interpretation of this Agreement.

20. Counterparts. This Agreement may be executed in any number of counterparts, each of which when so executed and delivered shall be deemed to be an original and all of which together shall be deemed to be one and the same agreement.

21. Notices. All notices and other communications provided for herein shall be in writing and shall be deemed to have been duly given if delivered personally or sent by registered or certified mail, return receipt requested, postage prepaid to the following addresses (or such other address as either party shall have specified by notice in writing to the other):

25. Severability. If any term or provision of this Agreement is invalid, illegal or unenforceable in any jurisdiction, such invalidity, illegality or unenforceability shall not affect any other term or provision of this Agreement or invalidate or render unenforceable such term or provision in any other jurisdiction.

26. Independent Nature of Investors’ Obligations and Rights. The obligations of each Investor under this Agreement are several and not joint with the obligations of any other Investor, and no Investor shall be responsible in any way for the performance or non-performance of the obligations of any other Investor under this Agreement. Nothing contained herein, and no action taken by any Investor pursuant hereto, shall be deemed to constitute the Investors as a partnership, an association, a joint venture or any other kind of entity, or create a presumption that the Investors are in any way acting in concert or as a group with respect to such obligations or the transactions contemplated hereby. Each Investor shall be entitled to independently protect and enforce its rights, including, without limitation, the rights arising out of this Agreement, and it shall not be necessary for any other Investor to be joined as an additional party in any proceeding for such purpose. Each Investor has had the opportunity to be represented by its own separate legal counsel in its review and negotiation of this Agreement (including the exhibits and schedules hereto). Except as expressly contemplated by this Agreement, the Company has elected to provide all Investors with the same terms and Agreement for the convenience of the Company and not because it was required or requested to do so by any of the Investors.

IN WITNESS WHEREOF, the parties hereto have caused this Agreement to be duly executed by their respective authorized signatories as of the date first indicated above.
