BUSINESSOverviewYield10 Bioscience, Inc. is an agricultural bioscience company focusing on the development of new technologies to enable step-change increases in cropyield to enhance global food security. We consider 10-20 percent increases in crop yield to be step-change increases. According to a United Nations report, foodproduction 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 morethan 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 onscarce water resources. Harvestable food production per acre and per growing season must be increased to meet this demand.Yield10 is using two proprietary advanced biotechnology trait gene discovery platforms to improve fundamental crop yield through enhancedphotosynthetic carbon capture and increased carbon utilization efficiency to increase seed yield. These platforms are based on the principle that plants whichcapture and utilize carbon more efficiently will enable more robust crops capable of increased seed yield. Yield10 is working to develop, translate and demonstratethe commercial value of new genetically engineered yield trait genes, identified in our discovery platforms, in major crops and to identify additional genomeediting targets for improved crop performance in several key food and feed crops, including canola, soybean, rice and corn. Yield10 Bioscience is headquartered inWoburn, Massachusetts and has an additional agricultural science facility with greenhouses in Saskatoon, Saskatchewan, Canada.Yield10 Bioscience was founded as Metabolix, Inc. in 1992 and originally focused on redirecting carbon flow in living systems to produce bioplastics andbiobased chemicals. In 1997, Metabolix started a crop science research program with the intent to produce the microbial bioplastic polyhydroxybutyrate ("PHB") inhigh concentration in the seeds of oilseed crops or in the leaves of biomass crops where it acts as an additional carbon sink or carbon store. As we made progress onour crop program, we learned that the rate of carbon supply from photosynthesis was a bottleneck to the effective utilization of3Table of Contentscarbon, 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 promisingproprietary yield trait genes.Based on encouraging early results from these gene discovery programs, we refocused our crop science efforts to yield improvement in major food andfeed crops in 2015 and rebranded the effort as Yield10 Bioscience. In 2016, we sold our biopolymers assets and restructured the Company around our crop sciencemission. In January 2017, we completed this transition and changed the name of the company to Yield10 Bioscience, Inc. We are developing proprietary,breakthrough plant biotechnologies to improve crop productivity and seed yield based on two proprietary discovery platforms:•the “Smart Carbon Grid for Crops Platform,” — in which we are working to eliminate bottlenecks in plant photosynthesis and carbon metabolism byharnessing new metabolic capabilities from non-plant systems including microbes and algae, and;•the “T3 Platform,” — in which we have identified three powerful global regulator genes in plants which control complex regulatory networks andgene cascades resulting in step-change increases in photosynthetic carbon fixation and biomass yields. Molecular genomic analysis of high yieldingplants developed using these genes has identified a series of additional crop trait gene targets. Genetic engineering of this new series of crop trait genetargets can be accomplished using only DNA sequences from the crop target species or through genome editing, potentially reducing regulatory costsand timelines.In our work to date, our team has demonstrated step-change yield increases in Camelina seed production and in switchgrass biomass production. We are currentlyprogressing the development of our lead yield trait genes in canola, soybean, rice and corn to provide step-change crop yield solutions for enhancing global foodsecurity.With these two platforms, we have established a series of proprietary trait genes to enhance carbon dioxide capture and fixation in both C3 and C4photosynthetic plants for yield improvement. C3 photosynthesis, the simplest type of plant photosynthetic system, exists in most agricultural crops used for humanconsumption, and includes canola, soybean, rice, wheat and potato. C4 photosynthesis is a more complex system. Plants using the C4 system have evolved anadditional distinctive cellular structure, in which carbon dioxide is concentrated for the main photosynthesis enzyme RUBISCO through a series of metabolic andmetabolite transports known as the C4 pathway. Corn and sugarcane are part of the C4 photosynthetic plant family. In general, C4 photosynthetic plants have up tofive times inherently higher plant yield than plants in the C3 photosynthetic family. This difference in plant yield is a result of evolution, which has led plantscientists to consider the possibility that new genetic enhancements can be created to fundamentally improve the photosynthetic system in C3 plants.Over the last 18 months, we have consolidated our crop science intellectual property position with approximately ten patent filings in prosecution,identified additional novel gene targets for improving crop performance and yield through genetic engineering or genome editing, formed a scientific advisoryboard with leaders in plant science, conducted several greenhouse studies and conducted our first Fast Field Testing of traits from our “Smart Carbon Grid forCrops” discovery platform. We have reported encouraging data for our lead yield trait gene, C3003 in Camelina from greenhouse and field tests and are conductingadditional studies in Camelina, canola, soybean and rice.Crop yield is the primary driver of the agriculture value chain. Yield can make the difference between a profitable season and losses for growers. As such,technologies to protect crop yield or increase it are the primary determinant of the seed buying decision by growers at the start of the season. This in turndetermines both revenue and market share for the major seed players. Yield10’s goal is to discover, optimize and translate our yield trait gene innovations intomajor food and feed crops and demonstrate the economic value to growers and seed companies. In all cases our trait genes will be introduced using geneticengineering technologies either to introduce new genes, to introduce additional copies of genes from the same crop species with modified regulatory sequencesfrom that crop species or by using genome editing technologies to reduce or eliminate the function of specific plant gene targets in individual crops. The method bywhich we deploy our yield trait genes has significant regulatory implications, which, in turn can affect the timelines and cost of their commercialization. We intendto create high-value assets in the form of proprietary yield gene technologies and to de-risk these assets by progressing them along the path to commercialdevelopment with increasingly larger scale field tests and multi-site field trials in major crops. We are deploying our yield trait genes into canola, soybean andcorn. We are engineering these traits into the major crops with the goal that they will be suitable for the regulatory approval process and in crop varieties(germplasm) such that our traits can be readily introduced into the industry’s elite crop lines by plant breeding.4Table of ContentsThe Unmet Need: Global Population Growth Outpacing Anticipated Global Food SupplyYield10 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 foodproduction 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 variableweather patterns. Solving this problem is a major global challenge requiring new crop innovation and technologies to fundamentally enhance crop productivity.The Yield GapAccording to several studies described in an article published in the Public Library of Science in 2013, crop yields may no longer be increasing indifferent regions of the globe, and current rates of crop yield increase are expected to fall significantly behind the levels needed to meet the demand for global foodproduction. The researchers found that the top four global crops - maize (corn), rice, wheat and soybean - are currently witnessing average yield improvements ofonly 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, by2050, in order to meet the anticipated increase in demand for food production caused by population growth. For corn and soybean, the benefits of currentlyavailable Genetic Modification ("GM") traits were already factored into the data cited in the studies referenced above. The yield increases needed to meet thedemands 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 (syntheticbiology approaches) to “build better plants,” in which technology is deployed to make the process of photosynthesis within plants more efficient at capturingatmospheric carbon and depositing that carbon in seed or biomass, with the effect of improving the overall yield of important food crops. Enhancement of thephotosynthetic 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 on the area of increasing photosynthetic carbon capture and crop yield technologies since 2012. As a result, wehave identified a number of exciting genes for increasing yield or improving crop performance.Business StrategyOur goal is to build a successful agricultural biotechnology company centered on demonstrating the value of our yield traits in major food and feed crops.We have identified and are evaluating novel yield trait genes that we have discovered using our two technology platforms. We believe we have extensive andunique metabolic engineering capabilities that can be deployed to help address the growing global yield gap in food and feed crops. As the primary driver offinancial 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, can be expected to generate significant value to the seed and cropindustry. For example, Yield10 is targeting an approximately 20 percent increase in canola and soybean yields, which, if successfully deployed across NorthAmerican acreage, would result in annual incremental crop value of $10 billion. By ultimately increasing the output of major food and feed crops and potentiallyreducing 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 inelite seed germplasm to provide the best options for farmers, Yield10 does not expect to become an integrated seed company. The current major seed playersdominate the GM crop space based largely on the early technology innovations that resulted in herbicide and pest resistance traits and have a very successfuloperating track record in the sector. Therefore, rather than replicating the downstream elements of these operations and developing our own regulatory, cropbreeding or seed production capabilities, we intend to seek industry collaborations and partnerships to leverage these existing core competencies of the current seedindustry. Yield10 will focus on its core competency, which is breakthrough science and technology innovation.Yield10 plans to build on its core strengths bringing new technology approaches to exploit an innovation gap in the agricultural biotechnology space dueto reduced investment in basic research and development resulting from the ongoing consolidation and restructuring in the agricultural sector. Yield10’s mission isto translate and optimize our step-change yield5Table of Contentstrait innovations into the major food and feed crops, and demonstrate their economic value to farmers and seed companies. We intend to create high-value assets inthe form of proprietary yield trait gene technologies and to de-risk these assets by progressing them along the path to commercial development with increasinglylarger scale field tests and multi-site field trials in major crops. We are currently deploying our yield trait genes into canola, soybean and corn, by designing andprogressing genetically engineered events suitable for the regulatory approval process which can be readily bred into the industry's elite crop lines by plantbreeding. We expect the customers for Yield10’s innovations to be the large and mid-size agricultural companies that would either license or acquire rights toYield10’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 globalpopulation. 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 7billion to more than 9.6 billion by 2050. Global climate change is also resulting in regional shifts to historical growing conditions. Given the projection forpopulation growth, recent studies show a “yield gap” for major food and feed crops that studies show cannot be addressed by incremental improvements to yieldbrought about by traditional plant breeding and existing GM traits. Current GM traits in the industry are based primarily on using microbial-sourced genes toimpart yield protection through herbicide, pest, disease and even drought resistance, whereas Yield10 is focused on increasing fundamental crop yield throughenhanced carbon capture and utilization.Yield10 is fundamentally focused on “building better plants” based on using genetic engineering technologies to deploy new yield trait genes that improvethe efficiency of photosynthesis and the efficiency of converting fixed carbon to seed and/or introducing targeted genetic changes in the plant genome that allowthe plant to make more seed or biomass.Our HistoryWe have a significant track record and expertise in the metabolic engineering of microbes and have made significant progress translating this capability toplants.As part of the legacy biopolymers and biobased chemicals business of our predecessor company Metabolix, our research team developed an advancedmetabolic engineering capability to alter key biochemical pathways and redirect the flow of carbon metabolic intermediates in microbes resulting in the productionof the biomaterial polyhydroxyalkanoate or PHA, at a level of more than 80 to 90 percent by weight of microbial cells that normally did not produce any PHA.Through our experience producing PHA in plants we have demonstrated that our experience with re-engineering the metabolism of microbes can be translated to“building better plants.” In 1997, Metabolix initiated a crop science research program to produce renewable bioplastics and chemicals from agricultural crops. Historically, these efforts were focused on producing PHB, a microbial carbon storage biopolymer, in high concentration in the seeds of oilseed crops or in theleaves of biomass crops such as switchgrass.As we made progress on producing PHB in plants, we learned that basic carbon supply from photosynthesis was a bottleneck. To address this carbonshortfall, we began developing new metabolic engineering and bioinformatics approaches to enhancing basic crop photosynthetic carbon capture. Discoveries fromthese two approaches became the foundation of our “Smart Carbon Grid for Crops” and “T3 Platform” crop trait discovery platforms, respectively. We also beganbuilding intellectual property on novel yield trait gene technologies discovered in these programs. Photosynthesis is the most important biological processresponsible for global food production. For example, according to the USDA, the output of U.S. farms contributed $177 billion, or one percent, to GDP in 2014.Improving the photosynthetic capacity of plants is an essential first step to increase the performance of crops 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 toseed. Key to achieving this is increasing the rate of net photosynthetic carbon capture. Once a plant has fixed carbon, that fixed carbon can be directed to threedifferent places: it can be used to make roots, leaf and stem tissue of biomass, used for seed or it can be released again as CO 2 through normal metabolic processes.In 2015 and 2016, we made significant progress applying our “Smart Carbon Grid for Crops” platform to plants. Using this technology platform, whichwe established as a result of a series of government funded internal programs and external academic collaborations, we have developed metabolic engineeringstrategies using microbial genes to introduce new functionality into plants to increase photosynthesis by making key metabolic pathways in plants more efficient,and to6Table of Contentseliminate bottlenecks to efficient carbon usage. This approach is similar to what has been the bedrock of the agricultural biotech seed industry, the introduction ofgenes from non-plant systems to enable new functionality in the form of herbicide, pest resistance and drought tolerance. Our approaches led not only to theidentification of novel yield trait genes but also encouraging early yield data from field studies with our lead yield trait gene in the industrial oilseed Camelina.Our ApproachWe have two unique, proprietary technology platforms for identifying novel yield trait genes.Our unique approach consists of two core technology platforms. The first is based on our 30 years of experience optimizing the flow of carbonintermediates in living systems and is called the “Smart Carbon Grid for Crops.” Using this approach and working with our partners in academia, Yield10 hasdemonstrated major step-changes in seed yield in the industrial oilseed Camelina. We currently have four novel trait genes impacting seed yield, which we refer toas: C3003 through C3006, and we are progressing our lead yield trait gene C3003 in our key crop targets canola, soybean and corn. Recently, we reported seedyield increases of up to 23 percent in early field tests conducted in 2016 with Camelina.In our second platform, the “T3 Platform,” we developed a proprietary computational process to identify global transcription factor (GTF) genes, ormaster switches, which algorithms predicted could both up-regulate or down-regulate multiple gene cascades with the potential for increasing photosynthesis,reducing bottlenecks in central metabolism and positively impacting plant and biomass yield. We have tested the three lead gene targets experimentally and haveshown that they produced average increases of over 40 percent in photosynthetic carbon fixation, flow of carbon through central metabolism and biomass levels inour experiments with switchgrass. In some cases the biomass yield has been increased up to 70 percent in preliminary greenhouse tests, a notable finding given thatswitchgrass is a high yielding C4 photosynthetic crop. Although it is a very useful model for C4 photosynthesis plants, switchgrass is not a food crop, so weidentified the corresponding genes in major food crops including our key targets, soybean, rice and corn, and we are currently progressing these trait genes in thosecrops.Our work with the Smart Carbon Grid for Crops and the T3 Platform has identified promising potential targets for genome editing. We believe that theseapproaches may be subject to less regulatory complexity in the U.S. during development and along the path to commercialization, and may provideopportunities for licensing.Genome editing techniques, including CRISPR/Cas9, which involve making small targeted changes to the DNA of a target organism, have been ofinterest to the agricultural biotechnology industry because this approach is believed to have the potential to significantly reduce development costs and regulatorytimelines for crop trait development and market introduction. Announcements from Dupont and the United States Department of Agriculture - Animal and PlantHealth Inspection Service ("USDA-APHIS") regarding a clarification on the regulatory path for a genetically edited corn line indicated that this line will not besubject to regulations typically used for genetically modified crops on the basis that while the plant DNA was edited, the final plant did not contain any remainingforeign DNA (i.e. DNA sequences not from the plant being engineered) from the procedure used to edit the plant. This industry example suggests that crops thatare genome edited may not be subject to certain GMO regulations in the U.S., an outcome supported by recent developments in the USDA APHIS review of thecurrent regulatory process for crops made using genetic engineering. This has opened the potential for Yield10 to exploit a second tier of novel traits addressablewith genome editing. The challenge now for the agricultural biotechnology sector will be to identify gene targets for genome editing which can generate economicvalue.Yield10 has identified from its internal discovery platforms and in-licensed through academic collaborations a number of gene targets for genome editingin crops. In the course of our work, we have introduced genes coding for new metabolic pathway enzymes or global transcription factors producing high yield lineswith higher rates of photosynthetic carbon fixation. We are studying our high yield plants at the molecular level using advances in high throughput analyticalsystems at the whole genome level to look at what happens to every other gene in the plant as a result of the changes we have engineered in, focused specifically onwhich native plant genes are turned on or off. Genes whose activity is turned on in the high yield lines are worth further study on their own and genes whoseactivity is turned off are interesting candidates for genome editing. This type of molecular analysis of the high yielding lines where the flow of carbon is higher hasgiven us insights into key steps to target for further improvement. We have recently made progress deploying genome editing technology against the first of theseadditional targets in Camelina. We expect to increase our level of effort in this area in other crops, particularly canola, over the course of 2017, eventuallyexpanding into soybean, rice and corn. We believe our genome editing targets as well as the improved crops we develop using this approach may enable us to formcollaborations or license arrangements with a broader set of commercial partners and bring these forward into development in the near-term.7Table of ContentsWe plan to use any revenues we generate from license agreements around our genome editing targets to support our ongoing research and development efforts toenable step-changes in crop yield.We are developing the Camelina Fast Field Test model system to 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 thisis 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 fordiscovery research have not been suitable for studies in the field and are not representative of the advanced seed or crop varieties (germplasm) used in commercialproduction, which have been subject to decades of intensive breeding to improve yield. Translating success when introducing non-plant genes into major crops hasbeen very successful and the current biotech seed sector, which accounted for 444 million acres of crops worldwide in 2015 is based on using microbial genes inplants. 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 thiswill 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 modelfor identifying promising new yield traits for canola and soybean. It is also very fast to modify and develop genetically stable seed sufficient for 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 andimmediately begin putting them into canola and soybean, where the timelines to transform plant lines and generate field data are much longer. We can thenprogress 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 canthen 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 theresults of our Fast Field Testing in Camelina. For example with the longer development timelines needed to get canola and soybean ready for field testing, weexpect to initiate additional modifications earlier in these crops, having identified the potential to further improve the outcome based on the results of our Fast FieldTesting in Camelina. We have started deploying this process with our first trait C3003, in which we conducted Fast Field Testing in 2016, and plan to conductadditional studies in both Camelina and canola in 2017.We are using this process to de-risk and accelerate the demonstration of the trait gene value in major crops through the use of Fast Field Testing in amodel system. 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 fromthe 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 licensingdiscussions earlier while preserving the opportunity to capture a meaningful share of the upside value.If results of testing new yield traits in our Camelina Fast Field Testing model are shown to be predictive of results that can be obtained in other C3 crops, wemay be able to accelerate translation of new traits into important food and feed crops.We developed our Camelina Fast Field Testing model as a system to develop and optimize yield traits based on novel metabolic pathways. We havesignificant expertise in the genetic transformation and breeding of Camelina. We believe that if we can show that the results we obtain for potential yield traits aredirectionally predictive for the results we obtain in oilseed crops and other C3 crops, then we will be able to use the system to effectively screen for novel traits andaccelerate their deployment into additional crops having the C3 photosynthetic system, including canola, soybean, rice and wheat. For this reason, our CamelinaFast Field testing system may prove to be a valuable tool for novel yield trait discovery facilitating translation into commercially important crops.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 cropproduction in western North America. Our oilseeds team is based in Saskatoon, Saskatchewan, with laboratories in the NRC Plant Biotechnology Institute ("PBI")and commercial greenhouse and laboratory facilities at nearby Innovation Place. Our team has developed and implemented technology to improve and accelerateengineering, trait evaluation and breeding of Camelina and canola. The team also plays a key role in designing and conducting greenhouse and field tests requiredto effectively evaluate novel yield traits.8Table of ContentsWe have established a lean organizational footprint which is capable of evaluating our initial novel yield traits in greenhouse and field tests while maintainingefficient use of cash resources.As of December 31, 2016, we had 20 full-time employees, with the majority directly involved with our research and development activities. We believethat our organizational capabilities are aligned with our research priorities and are complemented by our use of third party infrastructure and certain serviceproviders. 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 will allow us to focus our limited resources on deploying our core strengths against our key development goals. We expect to grow our research anddevelopment operations over time commensurate with building value in our business and advancing our traits through development while at the same time tightlymanaging overhead costs.We have established academic collaborations which provide us with opportunities to access government grant revenue to support our research as well as keyintellectual property.Yield10 has pursued academic collaborations that have led to the discovery of novel yield trait genes. Researcher Danny Schnell, Ph.D. discovered theC3003 trait in an ARPA-e funded collaborative project at the University of Massachusetts in which Yield10 was a partner. In 2015, Prof. Schnell moved toMichigan State University where he is Chairperson, Department of Plant Biology and remains a collaborator. Heike Sederoff, Ph.D. Professor, Department of Plantand Microbial Biology at North Carolina State University developed the C3004 and C3005 traits with ARPA-e funding which Yield10 is now progressing under alicense agreement. Both Dr. Schnell and Dr. Sederoff are members of our Scientific Advisory Board. In early 2017, Yield10 announced taking an option to a globallicense agreement from the University of Missouri. This license covers a genome editing target based on the recent discovery of a key regulatory mechanismcontrolling oil production in oilseed crops which can be used to increase the oil content. Oil content is the key economic driver in crops such as canola, sunflowerand safflower. We plan to exercise this option later in 2017.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, identify novelyield traits and test novel yield traits in Camelina. This work is valuable because traits developed in Camelina have the potential to be developed and deployed inother oilseed crops. We plan to continue to pursue government grants to defray research costs associated with our research and development activities.We plan to deploy our novel yield trait genes to generate proof points across a range of crops.Current biotech-generated crop protection traits such as “Roundup Ready” and insect resistance are deployed broadly in the Americas in the canola,soybean and corn crops. For novel yield trait genes, such as C3003, we envision deployment of the trait in C3 photosynthetic oilseed crops such as Camelina,canola and soybean and potentially in other C3 crops such as rice, alfalfa, cotton, potato and wheat. We are currently testing C3003 and C4003 in rice wheregenetically modified plants have not yet been widely introduced commercially. We also believe there is an opportunity to deploy our novel yield traits into existingGM crops as “stacked traits” included in branded seeds marketed and sold to farmers. “Stacked traits” refers to the practice of adding multiple biotech traits to anelite plant line as a strategy to further increase value.In addition we view our genome editing targets as a complement to plant breeding techniques and plan to test our genome editing targets in oilseed crops,as well as in rice, corn and forage crops as a way to improve seed yield and/or biomass and generate opportunities for licensing or collaboration with establishedindustry partners.We believe our business model will allow us to capture value for our discoveries and provide a path to commercialization for important new yield traits formajor crops.We are positioning Yield10 as a discovery company whereby we will work to advance our own developments as well as form business alliances toprogress our traits through development and early commercialization. Our goal is to capture an attractive share of the added economic value resulting from thedeployment of our trait genes and technologies in key crops. We are currently working on the development and deployment of our trait genes into canola, soybean,rice and corn, an approach facilitated by the expiration of much of the early foundation patents in the agricultural biotechnology sector, and one of our keyobjectives in that regard is to demonstrate commercial proof points through multi-site field tests. Yield10 has a number of opportunities and models for valuecapture including partnering or licensing with established agricultural industry players. Key to our strategy is to retain, where practical, control of timelines andmaximize, where possible, the opportunity for value creation and optionality around future exit strategies.9Table of ContentsTechnology PlatformsIn 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 planto build value by leveraging genome editing targets for revenue generation in the near-term while we independently work to demonstrate the economic value of ourtransformative genetic engineering based yield breakthroughs in the longer term. The recent expiration of early blocking patents on plant genetic engineeringmeans we can now be more effective in research and development, leverage third party service providers and independently drive key proof points in majorcommercial crops such as canola, soybean and corn while focusing our resources on our core strengths. Yield10 is focused on increasing the inherent yield of majorfood and feed crops. With regard to forming collaborations, we recognize there are considerable headwinds to overcome in this sector, including industryskepticism based on disappointing outcomes from major investments made screening large numbers of single crop genes. This has resulted in a challengingenvironment for early crop innovations prior to demonstration of key proof points in commercial crops. Our goal is to “build better plants” which requires newapproaches and innovation and in our view will most likely involve gene combinations and/or multi-gene systems.Increasing crop yield is a complex two-step carbon optimization problem. Harvested seed is mostly carbon fixed from carbon dioxide in the air byphotosynthesis with oxygen coming from water in the soil and smaller amounts of nitrogen and phosphate both of which are applied as fertilizer. To achieveincreased 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 thatincreasing seed yield will likely require multiple trait genes to increase carbon fixation by photosynthesis at the front-end and direct the increased fixed carbon tothe seed. One analogy would be the fact that simply filling the gas tank in a car does not make it go faster. If successful in increasing photosynthesis, we expect toreach metabolic bottlenecks downstream, some of which will likely prevent some of the additional fixed carbon from reaching the seed. However, with newanalytical tools available we expect to be able to identify bottlenecks and develop solutions to achieve our targeted outcomes, step-change increases in seed yield.This leads to our theme of enhanced carbon capture from photosynthesis and targeted carbon deposition to seed.Plants can be categorized generally into two different groups based on their system of photosynthesis. C3 photosynthesis, the simplest type of plantphotosynthetic system, exists in most agricultural crops used for human consumption, and includes canola, soybean, rice, wheat and potato. C4 photosynthesis is amore complex system. Plants using the C4 system have evolved an additional distinctive cellular structure, in which carbon dioxide is concentrated for the mainphotosynthesis enzyme RUBISCO through a series of metabolic and metabolite transports known as the C4 pathway. Corn and sugarcane are part of the C4photosynthetic plant family. In general, C4 photosynthetic plants have up to five times inherently higher plant yield than plants in the C3 photosynthetic family.This difference in plant yield is a result of evolution, which has led plant scientists to consider the possibility that new genetic enhancements can be created tofundamentally improve the photosynthetic system in C3 plants.Smart Carbon Grid for Crops Technology PlatformYield10 is leveraging over a decade of metabolic engineering experience to optimize photosynthetic carbon capture and utilization in plant systems, whichis critical to increasing seed yield. The “Smart Carbon Grid for Crops” is an advanced metabolic engineering platform that we believe has the potential to addresswell known metabolic limitations in crops and in C3 crops in particular. Similar to the electric grid where much of the investment made to generate the power islost in the distribution system, plants having the C3 photosynthestic system are similar in that they lose over half the carbon the grower has paid to fix in input costsdue to metabolic inefficiencies. We plan to mirror an approach taken by many of the current herbicide and pest resistance GM traits where genes from non-plantsources were used successfully to impart new functionality to crops. In our case, we are exploiting non-plant genes such as genes from microbial or algal sources tofix or reduce the impact of well-understood carbon capture metabolic pathway limitations in C3 crops. For example, photorespiration is a wasteful side reaction orcarbon capture inefficiency in crops having the C3 photosynthetic system which represent approximately 70 percent of the food consumed by humans and includewheat, rice, soybean, canola and potato. We believe reducing photorespiration should lead to improved net carbon fixation from photosynthesis and as a result, wewould expect to see step-change increases in seed yield.To illustrate the value creation potential, yield loss in C3 crops due to photorespiration was recently quantified in a paper published in the AnnualReviews of Plant Biology. The authors estimated that yield in U.S. soybean crops is reduced by 36 percent and the yield in U.S. wheat crops is reduced by 20percent due to photorespiration. They also estimated that achieving a five percent reduction of photorespiration in soybean and wheat in the U.S. would addapproximately $500 million per year of value. Some models suggest that photosynthesis could improve by 12 to 55 percent in the absence of10Table of Contentsphotorespiration. Therefore, photorespiration has been a major topic in plant science and researchers have employed multiple strategies in attempts to reducephotorespiration in C3 plants as a means to improve yield.Reducing photorespiration is one of the key targets of our Smart Carbon Grid for Crops technology platform. This platform is an innovative, systemsbased approach to boost yield by increasing the amount of carbon fixed by photosynthesis and targeting the increased carbon to harvestable seed. Our lead trait,C3003, has been shown to enhance carbon fixation and seed yield in the oilseed Camelina where it impacts photorespiration. C3003 is a scientific discovery madein one of our academic collaborations and Yield10 has exclusive rights to this technology. While our collaborator continues to work on characterizing themechanism of this yield trait gene, current data suggests C3003 is a very unique gene that reduces photorespiration in an unexpected manner. New science alsorepresents a key aspect of de-risking our technologies. If the science provides new insights or addresses a well-defined bottleneck in a key limiting pathwaycommon to a large number of crops, then the expectations for broadly translating initial results should be higher. We are excited about the prospects of C3003 inreducing the well-known yield losses that occur through photorespiration in C3 crops. We are currently studying C3003’s effect in the food crops canola, soybeanand rice. 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 themolecular 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 believe the C3004 trait gene is involved in controlling the flow of fixed carbon toseed as part of the plants natural regulatory system. It is well known that the flow of carbon in plants is tightly controlled and we believe our approach toengineering the C3004 gene using genome editing has the potential to remove one of these control points and can be combined with the C3003 trait gene to furtherincrease yield beyond what can be achieved with C3003 alone.T3 Platform and Plant Targets for Genome EditingIn crops having the evolutionary 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 metabolicallyefficient. Leveraging the industry's significant investment in crop genomics research over the last 20 years, we developed the “T3 platform,” which is an algorithm-based approach to “big data” mining of publicly available genomics data sets. We focused not on individual genes but on specific gene expression patterns. Geneexpression patterns tell the researcher which genes are turned on and off under different growth conditions. With the T3 platform we wanted to identify and focusour activities on a small number of very important plant genes. Using this approach we were able to identify and select novel genes, which could function as globalregulators or master switches to control cascades of other genes and metabolic systems. The strategy was to use the T3 platform to significantly narrow the numberof candidate genes to be tested and then test them experimentally in our high throughput gene transformation platform in our C4 photosynthetic crop model system,switchgrass. We validated the T3 platform approach by verifying with experimental results the positive yield impact of the three gene targets we identifiedcomputationally, an exceptional hit rate. These three yield genes, C4001, C4002 and C4003, increased photosynthetic carbon capture and biomass production byover 40 percent in our switchgrass plants. In this case our early experiments have been successful in demonstrating the potential to increase the rate of carbonfixation even in a high yielding C4 crop.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 theflow of carbon to seed in these plants and have made considerable progress in this regard. Molecular analysis of high yielding plants expressing the globaltranscription factors has allowed the identification of 71 downstream transcription factors that are differentially expressed in the high yielding lines and thus arethemselves targets for genetic manipulation. The expression of some of these genes is down regulated in the high yielding plants making them exciting targets forgenome editing through well-known approaches such as CRISPR/Cas9. We are beginning to validate these second generation gene targets in switchgrass and havethus far validated the predicted role of the first three genes. These trait genes have been named C4004, C4005 and C4006. We know the industry has struggled todeploy downstream transcription factors to improve crops particularly in hybrid corn. However, we are optimistic that we will be more successful introducing ourglobal regulator genes given the impact we saw in our experiments, and we believe genome edited traits, particularly simple gene deletions, will be significantlyeasier to implement and translate across all varieties of a crop.11Table of ContentsFast Field Testing System in CamelinaOne of the challenges the agricultural industry has faced over the years is translating early crop science discoveries into value generating traits. This is inpart 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 notrepresentative of the advanced seed or germplasm used in commercial production which have been subject to decades of intensive breeding to improve yield. Thelong 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 amodel for testing novel trait genes called the “Fast Field Testing” system based on our Camelina oilseed platform. We believe that this system has the potential tobecome a valuable tool for our yield trait discovery and translation effort. Camelina is an industrial oilseed, with reasonable field performance providing a robustmodel for canola and soybean and is well suited to large scale multi-site field tests and larger scale trials. Camelina is a plant that can be readily geneticallymodified 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 fromthe identification of a potential yield trait gene or combinations of genes to field planting in about 12 months. In our Fast Field Tests, we collect and analyze abroad set of data on our transgenic plants including parameters such as stand establishment, flowering, maturity, seed weight, seed size, oil content and oilcomposition. We also perform molecular analysis on plants of interest. We are using our Camelina Fast Field Test system to identify and screen trait genes ofinterest while deploying them in parallel into canola, soybean and rice where the timelines to obtain stable plant lines and field data are longer.Traits in DevelopmentWith the benefit of more than five years of investment, the Company has been able to launch itself as Yield10 Bioscience with ownership or licensedrights to several crop trait genes in hand and with the lead yield trait gene C3003 well-positioned in terms of translation and demonstration in key crops. Yield10has exclusive rights through ownership or licensing or is preparing to file patent applications covering the trait genes listed in Table 1 below.Under our “Smart Carbon Grid for Crops” technology platform we have identified the C3000 series of novel yield traits based on establishing newmetabolic pathways in crops. We have tested our lead yield trait gene, C3003 in Camelina in both greenhouse and initial field tests and have reported results fromthese initial tests. We are moving this promising trait forward in additional crops including canola, soybean and rice and expect to report data once additionalgreenhouse tests and/or field tests have been completed and analyzed.Under our “T3 Platform” we have identified the C4000 series of novel yield traits and gene editing targets. We expect to progress in our C4 monocotmodel a select few of the C4000 series traits, global regulatory genes discovered through our T3 Platform research program which we have shown to significantlyenhance photosynthesis and carbon capture in switchgrass. We are also progressing the C4003 trait gene in rice using our internal resources and we expect to reportinitial rice data once greenhouse tests have been completed and analyzed.12Table of ContentsTable 1: Summary of our crop yield traits currently in development.

C3003 is a scientific discovery made in oneof our academic collaborations funded by ARPA-e, a division of the Department of Energy. Our academic collaborator is continuing work to characterize C3003.C3003 appears to be a very unique gene that impacts photorespiration, a biochemical pathway in C3 plants, which 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 and rice, and we expect todisclose additional results from a number of these activities throughout 2017. In the 2016 growing season, we conducted a small scale field test which was designed primarily to establish our Camelina Fast Field Testing platform andaccelerate the generation of field data for crop trait discovery and improvement. As part of this study, we planted stable Camelina seed lines expressing C3003. Inearly 2017, we reported field test results showing that C3003 produced significant improvements in seed yield where the best C3003 line produced a 23 percentincrease as measured by average seed weight per hectare. This result was statistically significant (p<0.05) as compared to control plants. In addition, the highestyielding line expressing the C3003 gene matured an average of six days earlier than the control plants. Expression of C3003 did not change the percentage of oilcontent in the seed as measured by the weight of the oil in relation to the weight of the seed.While expression of C3003 enabled some of the Camelina lines we tested to produce higher seed yields by weight per hectare, the individual seed size inthese lines was decreased as compared to controls, likely due to a change in carbon partitioning in the plant. This reduction in seed size was expected based on datafrom prior greenhouse trials and Yield10 is addressing this finding with our second generation C3003 trait which is expressed specifically in the seed tissue ofplants.We believe that the results of our 2016 field tests in Camelina are encouraging and suggest that our approach to engineering new metabolic pathways inplants has the potential to produce step-changes in crop yield. These results also illustrate that our Fast Field Testing system in Camelina may be a valuable tool foreffectively screening novel yield trait13Table of Contentsgenes and dynamically adapting our approach to trait development as we translate these improvements into commercially important crops.Based on prior greenhouse data suggesting that constitutive expression of C3003 in Camelina could increase overall seed yield, but produce this increasewith the production of smaller, lighter weight seeds, we produced a second generation C3003 where the C3003 gene is expressed only in seed tissue. We believethat the reason for the smaller seeds is that the added influx of carbon produced by C3003 produces a “bottleneck” in plant metabolism that results in theproduction of more, but smaller seeds. In 2016, we tested second generation C3003 in Camelina in greenhouse studies. In early 2017, we reported preliminarygreenhouse data showing that the second generation C3003 produced an increase in seed yield, while maintaining typical seed weight.Based on encouraging data produced in Camelina with first and second generation C3003, we are continuing to progress the evaluation of the C3003 genetrait in parallel in canola, soybean and rice, key target crops where step-change increases in seed yield would improve the prospects for global food security and webelieve create considerable economic value.We are planning to conduct additional field tests of C3003 in the 2017 growing season. In these studies, we plan to evaluate Camelina lines transformedwith each of our first and second generation C3003 trait as well as canola lines containing the first generation C3003 trait. Preparation and logistics for this study,including seed bulk up, contracts with service providers and regulatory permitting were underway in early 2017. We plan to report preliminary data from this fieldtest in fourth quarter 2017 once the field tests have been completed and resulting data analyzed.Prior to that, we expect to report results from greenhouse studies in 2017 with the first generation C3003 trait in canola. We also recently introduced thesecond generation C3003 trait into canola, and greenhouse data on seed yield and seed size may be available by the end of 2017 or early 2018. If the data meet ourexpectations, we may test second generation C3003 in canola in field tests in spring 2018.We are expanding our research into soybean by leveraging the capabilities and technical resources of a collaborator under an agreement in which Yield10retains all commercial rights. This activity is underway for both the first and second generation versions of the C3003 trait. Assuming the research plan remains ontrack, we expect to be able to report results from initial greenhouse studies in late 2017 or early 2018.We have also initiated the introduction of the first and second generation versions of the C3003 yield trait gene in rice and expect to report ourobservations from those studies when testing has been completed and results have been analyzed.We plan to leverage third party services where the resources and infrastructure are already in place to transform and test novel traits in corn lines. Webelieve this will enable Yield10 to cost effectively expand its capabilities and enable us to progress our corn targets at least to the stage of initial corn hybrid fieldresults.We also plan to selectively partner with others for the development of different crops and/or traits. In particular we expect to progress a select few of theC4000 series traits, global regulatory genes discovered in our T3 Platform which we have shown to significantly enhance photosynthesis and carbon capture in ourC4 monocot model plant switchgrass. In the meantime, we have been able to progress the C4003 trait gene in rice using our internal resources and we expect toreport initial rice data as soon as it is available.Target CropsOur initial work in our C3000 and C4000 series traits suggests that our technology may be applicable to a wide range of crops harvested for food andanimal 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 improvethe productivity of their land to meet rising demand for food and feed, and significant economic value would be createdIn considering our strategy to develop our technologies we segregate our trait genes into two classes: trait genes based on using non-plant genes to addnew functionality to crops which are by definition GM; and trait genes which we may be able to deploy outside of the GM regulations, which encompasses our traitgenes which 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 arenot currently GM. We plan to pursue our GM trait genes in crops which are currently GM and where the economics can sustain14Table of Contentsthe 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 issuefor some NGO groups regardless of the science. For our GM yield trait genes, we are targeting seed yield increases of the order of 10 to 20 percent over the currentelite 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 anindustrial oilseed for the production of biofuels, novel industrial lipids, and oleochemicals. In addition, its meal has been identified for development as an animaland fish feed supplement. While it is not currently a commercially significant crop, research suggests that efforts to improve seed yield, oil content and fatty acidcomposition, and tolerance to heat stress may expand the commercial adoption and cultivation of Camelina.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 acidprofile 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. Currentlythe vast majority of the canola grown in North America contains two seed enhancement technologies, herbicide tolerance and hybrid seed. Both Roundup Ready(Monsanto) and Liberty-Link (Bayer) varieties of canola are grown and were introduced to the market in 1990s. Approximately 22 million acres were planted inCanada and the U.S. in the 2016 growing season. Yield10 is targeting a 20 percent or greater increase in canola seed yield. With a 2016 harvest of 812 millionbushels of canola (Statistics Canada) and an average farm gate price of $10.00 per bushel, a 20 percent yield increase in canola represents a total potential addedannual value of $1.6 billion that could be shared among the players 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 infood 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 SouthAmerica, where a majority of the seed planted is genetically modified. Approximately 88 million acres of soybean were planted in the U.S. and Canada in the 2016growing season. According to the USDA, the U.S., Brazil and Argentina grow approximately 80 percent of global soybean production. Yield10 is targeting a 20percent or greater increase in soybean seed yield. With a 2016 U.S. harvest of 4.36 billion bushels (USDA) and an average farm gate price of $10.00 per bushel, a20 percent yield increase in soybean represents a total potential added annual value of $8.7 billion that could be shared among the players in the soybean valuechain.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 andfood 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 in1997. Currently, about 80 percent of maize/corn production in the U.S. is genetically modified. It was estimated that more than 90 million acres of corn wereplanted in North America in the 2016 growing season. The traits commonly used in today’s corn cultivars provide insect resistance and herbicide tolerance. Inmany GM seeds sold today, both of these traits are expressed (or “stacked” which refers to the practice of adding multiple traits to an elite plant line as a strategy toprotect yield). Europe has limited production of GM corn, where Spain is a leading producer of GM corn. In this case, the most widely used GM trait (Bt) protectsagainst 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 C4photosynthesis system and Yield10 is targeting a 10 percent yield increase in corn. With a 2016 U.S. harvest of 15.2 billion bushels and an average per bushel priceof $3.50, a 10 percent yield increase in corn represents a total potential added annual value of $5.32 billion that could be shared among the players in the corn valuechain.Rice is the staple food for over 50 percent of the global population. World crop production of rice was estimated at approximately 480 million metric tonsin 2016. 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 protect ricefrom weeds and insect pests. Additional biotechnology approaches are being taken to improve the nutritional value of rice. While Yield10 has not established atarget for yield improvement in rice, early work is underway to evaluate the potential of our technologies in this globally important food crop.Forage crops are grown expressly for biomass used for feeding livestock. Typical forage crops include both annual and perennial crops such as variousgrasses, silage corn, alfalfa and sorghum. Biotechnology traits have been previously introduced into silage corn and alfalfa. Other forage crops could be amenableto 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.15Table of ContentsRegulatory RequirementsSince the first successful commercialization of a biotechnology-derived crop in the 1990s, many new GM crop varieties have been developed and madeavailable to U.S. farmers and farmers worldwide. U.S. farmers have rapidly adopted many of these new GM varieties, so that in 2016, 92 percent of the corn, 93percent of the cotton, and 94 percent of the soybeans planted in the U.S. were varieties produced through genetic engineering. A significant percentage of theproduction of other crops, such as alfalfa, papaya and sugar beet, are also biotech-derived. Genetically modified crops are subject to a significant amount of regulation in the U.S. and around the world. Field tests and field trials of GM crops needto ensure that traits in development do not escape or mix with native plants. The U.S. Government agencies responsible for oversight of the products of modernagricultural biotechnology are the United States Department of Agriculture, the U.S. Environmental Protection Agency (EPA), and the U.S. Food and DrugAdministration (FDA). Depending on its characteristics, a product may be subject to the jurisdiction of one or more of these agencies under the federalgovernment’s 1986 Coordinated Framework for the Regulation of Biotechnology (most recently updated in January 2017). Regulatory officials from the threeagencies regularly communicate and exchange information to ensure that any safety or regulatory issues that may arise are appropriately resolved within the scopeof authority afforded to each agency under their respective statutes. Other environmental laws or regulations also may be implicated, depending on the specificproduct. Within USDA, the Animal and Plant Health Inspection Service (APHIS) is responsible for protecting agricultural plants from pests, diseases and noxiousweeds. Under the Plant Protection Act, USDA-APHIS has regulatory oversight over products of modern biotechnology that could pose such a risk. Accordingly,USDA-APHIS regulates organisms and products that are known or suspected to be plant pests or to pose a plant pest risk, including those that have been altered orproduced through genetic engineering. These are called “regulated articles.” USDA-APHIS regulates the import, handling, interstate movement, and release intothe environment of regulated organisms that are products of biotechnology, including organisms undergoing confined experimental use or field trials. Regulatedarticles are reviewed to ensure that, under the proposed conditions of use, they do not present a plant pest risk through ensuring appropriate handling, confinementand disposal. The developer may then petition USDA-APHIS for a determination of non-regulated status for the article. If the agency determines that the GE plantis unlikely to present a greater plant pest risk than its unmodified counterpart, the new crop will no longer be subject to the permitting and other regulatoryprocesses that are overseen by USDA-APHIS ( i.e. , it will no longer be treated as a potential plant pest). Subsequently, depending on the intended use of the non-regulated genetically engineered plant, the developer may need to work within separate EPA orFDA oversight rules before commercial introduction of the final product. EPA primarily regulates products of biotechnology that are intended for use aspesticides, under the authorities granted to EPA by the Federal Insecticide, Fungicide, and Rodenticide Act (FIFRA). FDA is the agency responsible for overseeingthe safety of biotechnology-derived products that are intended to be used as human or animal food, or that may end up in the food supply. Since 1992, FDA hashad in place a voluntary consultation process for developers of bioengineered food, and final agency decisions and other information from these BiotechnologyConsultations are made publicly available by FDA. Consultations are data-intensive and examine the new food product’s safety and nutritional profile, amongother issues. Generally, FDA has found that such food products do not pose unique health risks to humans or animals, but if a novel allergen or other distinctionfrom 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 madeaware of material differences between GE and conventional versions. In Canada, the largest producer of GM canola, GM crops and the food products into which they are incorporated also are regulated by multiple governmentagencies 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 agriculturalcommodities. The CFIA’s Plant Biosafety Office (PBO) is responsible for conducting environmental assessments of biotechnology-derived plants. Authority forthe PBO includes both approving confined field trials with the GM crop through permits and authorizing their “unconfined release” as a first step towardscommercialization. Second, under the Food and Drugs Act and related regulations, Health Canada is responsible for reviewing a pre-market safety assessment that must besubmitted by the manufacturer or importer of a “novel food,” a term of art which includes GM or biotechnology-derived foods. The safety assessment shouldprovide assurances that the novel food is safe when prepared or consumed according to its intended use. A multi-disciplinary team of experts from Health Canadawill evaluate the data and information about the novel food and make a determination regarding whether it can be sold in Canada,16Table of Contentsand whether any restrictions are warranted under applicable law or the product’s safety profile. Health Canada’s final decision documents regarding the safety ofthese novel foods are made publicly available by the government. 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 identifieda potential health or safety issues with a food that could be mitigated through labeling or other disclosures. For example, if the biotechnology-derived foodcontains 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 tothat 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 labelingrepresentations do not create a potential risk of fraud or consumer confusion and are compliant with Canada’s voluntary disclosure standard for geneticallyengineered food ingredients. Finally, Environment Canada is 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 andmunicipal permits and we must ensure compliance with all applicable regulations including regulations relating to GM crops. With laboratories and greenhouse inboth the U.S. and Canada, we are subject to regulations governing the shipment of seeds and other plant material (including GM seeds and GM 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 domesticagriculture.License Agreement with the University of MassachusettsPursuant to a license agreement with the University of Massachusetts ("UMASS") dated as of June 30, 2015, we have an exclusive, worldwide licenseunder certain patents and patent applications to make, have made, use, offer for sale, sell, have sold and import any transgenic plant seed or plant grown there fromor 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 transgenicplant 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.The licensed patent rights include issued patents covering our yield trait gene C3003.We are required to use diligent efforts to develop licensed products throughout the field of use and to introduce licensed products into the commercialmarket. In that regard, we are obligated to fulfill certain development and regulatory milestones relating to C3003, including completion of multi-site fielddemonstrations of a crop species in which C3003 has been introduced, and filing for regulatory approval of a crop species in which C3003 has been introducedwithin 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 apotential 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 oflicensed 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 immediatelyupon 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 agreementwith respect to certain patent rights immediately upon written notice in the event we contest the validity or enforceability of such patent rights.Agricultural Industry LandscapeFollowing advances in biotechnology in the 1970s through early 1990s, the first genetically modified crops were commercially introduced in the U.S. inthe 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 theirsupporters and their detractors over the years. Consumer sentiment including concerns about the safety of GM crops have limited the introduction and adoption of17Table of ContentsGM 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 444 million acresworldwide were planted with GM crops in 2015, the most recent year where data is available. The planting of GM crops is centered in the Americas with NorthAmerica at approximately 45.5 percent of the acres and Latin America at approximately 43 percent. China and India follow with approximately 8 percent and thebalance of the total worldwide GM crop acreage in 2015 was planted in European Union 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 European Union has been relatively slow to adopt GM crops and has relied heavily on plant breeding programs forcapturing crop yield improvements over the last 20 years. In 2013, Spain was the largest producer of GM crops in Europe, based on cultivation of GM cornrepresenting approximately 20 percent of the country’s crop that year. Certain GM crops have been approved for cultivation in some European countries, whileother 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 $53 billion in 2014 and is projected to growto more than $100 billion by 2022. According to an ISAAA report, the global GM seed business represented a $15.3 billion market in 2015. The traits beingcommercialized today by the agricultural industry mainly address crop protection, which involves preventing crop damage by weeds, insects and other pests thatlower expected crop yield. As technology has advanced, “trait stacking,” or the practice of adding multiple traits to an elite plant line, has become commonplace asa strategy to protect yield. As the industry has developed, the practice of inter-licensing traits between research and development driven seed companies has led toa 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, Dow, DuPont Pioneer, Monsanto,Syngenta and AgReliant. These companies have significant resources, experience and track records of successfully developing, testing and commercializing highperforming 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 theoverall cost of crop production to successful harvest. Many of these companies are involved in the current sector consolidation with the Dow/ Dupont merger andthe acquisition of Syngenta by ChemChina nearing completion and the acquisition of Monsanto by Bayer ongoing.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 themultinational companies and input these traits into elite plant germplasm to produce seeds optimized for a variety of soil, climate and field conditions. Bothcompanies 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 pestcontrol, agbiome strategies and precision agriculture. There are startups, privately held and publicly traded companies involved in this space. Such companiesinclude AgBiome, Arcadia Biosciences, Benson Hill Biosystems, Cibus, Evogene, Indigo, Kaiima, and Marrone Bio Innovation, many of which have greaterresources and experience than we have. Intellectual PropertyOur continued success depends in large part on our proprietary technology. As of December 31, 2016, we owned or held exclusive rights to 10 pendingpatent applications worldwide related to advanced technologies for increasing yield in crops. Our portfolio of patent applications includes plant sciencetechnologies we have in-licensed globally and exclusively from The University of Massachusetts and North Carolina State University related to the yield trait geneC3003 and other advanced technologies based on advanced metabolic engineering methods to improve carbon capture and selectively control carbon partitioning inplants.We continue to seek, develop and evaluate new technologies and related intellectual property that might enhance our Company's business strategy,industry position or deployment options.18Table of ContentsEmployeesAs of December 31, 2016, we had 20 full-time employees. Of those employees, 15 were in research and development. Among our staff, 7 hold Ph.D.’sand 11 hold masters’ or bachelors’ degrees in their respective disciplines. Our technical staff has expertise in the following areas: plant genetics, plant biology,microbial genetics, bioinformatics, metabolic engineering and systems biology. Our headquarters are located in Massachusetts, and we maintain a research anddevelopment facility, including greenhouse facilities, in Saskatoon, Canada. None of our employees are subject to a collective bargaining agreement. We considerour relationship with our employees to be good.Corporate History and Investor InformationWe changed our name to Yield10 Bioscience, Inc. in January 2017 to reflect our change in mission around innovations in agricultural biotechnologyfocused on developing disruptive technologies for step-change improvements in crop yield.

We caution you that the following important factors, among others, could cause our actual results to differmaterially from those expressed in forward-looking statements made by us or on our behalf in filings with the SEC, press releases, communications with investorsand oral statements. Any or all of our forward-looking statements in this Annual Report on Form 10-K and in any other public statements we make may turn out tobe wrong. They can be affected by inaccurate assumptions we might make or by known or unknown risks and uncertainties. Many factors mentioned in thediscussion below will be important in determining future results. Consequently, no forward-looking statement can be guaranteed. Actual future results may differmaterially from those anticipated in forward-looking statements. We undertake no obligation to update any forward-looking statements, whether as a result of newinformation, future events or otherwise. You are advised, however, to consult any further disclosure we make in our reports filed with the SEC.All dollar amounts, except per share amounts, are stated in thousands.19Table of ContentsRisks Relating to our Financial PositionWe 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 theterms of any financings may not be advantageous to us.As of December 31, 2016, we held unrestricted cash and cash equivalents of $7,309 . Although we have $20,000 of availability under our equity facilitywith Aspire Capital, market conditions likely will limit the extent to which we can draw on this facility. Our present capital resources may not be sufficient to fundour planned operations for a twelve month period, and therefore, raise substantial doubt about our ability to continue as a going concern.In 2016, we completed a strategic restructuring under which Yield10 Bioscience has become our core business, with a focus on developing disruptivetechnologies for step-change improvements in crop yield to enhance global food security.We will require additional capital resources to support the implementation of this new strategy and we may pursue one or more of a variety of financingoptions, including public or private equity financing, secured or unsecured debt financing, equity or debt bridge financing, as well as licensing or othercollaborative arrangements. There can be no assurance that our financing efforts will be successful. If we are not able to secure such additional capital resources orotherwise fund our operations, we may be forced to explore strategic alternatives and/or wind down our operations and pursue options for liquidating our remainingassets, including intellectual property and equipment.We continue to face significant challenges and uncertainties. Our future revenues, expenses and cash usage will depend on the successful execution of ourstrategic plans related to Yield10 Bioscience. Adequate financing to implement our new strategy may not be available. Available capital resources may beconsumed more rapidly than currently expected due to any or all of the following:•higher restructuring costs than anticipated;•lower than expected revenues from grants, licenses, and service fees related to our Yield10 Bioscience 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.If we issue equity or debt securities to raise additional funds, we may incur fees associated with such issuances, our existing stockholders may experiencedilution 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 connectionwith 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 theInternal Revenue Code of 1986 due to ownership changes resulting from equity financing transactions. If we raise additional funds through collaboration, licensingor other similar arrangements, it may be necessary to relinquish valuable rights to our potential products or proprietary technologies, or grant licenses on terms thatare not favorable to us.We have a history of net losses and our future profitability is uncertain.With the exception of 2012, when we recognized $38,885 of deferred revenue from a terminated joint venture, we have recorded losses since ourinception. At December 31, 2016, our accumulated deficit was $333,357 . 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 businesswill generate sufficient revenue to become profitable. We expect to have significant losses and negative cash flow for at least the next several years, as we incuradditional costs and expenses for the continued development of our technology, including the ongoing expenses of research, development, commercialization andadministration. 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 thenumber 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 beprofitable or achieve significant revenues.20Table of ContentsWe 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 ofdevelopment. 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 corebusiness. 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. We currently anticipate that our annual net cash used in operations, including anticipated payments forrestructuring costs, will be approximately $7,500 - $8,000, compared to approximately $25,000 prior to the restructuring.The remaining cash restructuring costs associated with our strategic repositioning are estimated at approximately $2,048 , which have various paymentdue dates through May 2018. However, the reduction in cash used in operations resulting from the restructuring may be less than expected. If we are not successfulin reducing our cash used in operations, we may require more financing than anticipated or we may be forced to wind down our remaining operations.The products and technologies we are currently developing as a result of our strategic repositioning are at a very early stage of development, and theprocess of developing them is lengthy and uncertain. In addition, our current management has limited experience in developing technologies for the crop scienceindustry, 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 toachieve revenue from their license or sale.We currently do not meet the continued listing standards of The NASDAQ Capital Market, which require a minimum closing bid price of $1.00 per share. Ourfailure to meet NASDAQ’s continued listing standards could result in the delisting of our common stock, negatively impact the price of our common stock andnegatively impact our ability to raise additional capital.Our common stock is listed on The NASDAQ Capital Market. NASDAQ provides various continued listing requirements that a company must meet inorder for its stock to continue trading on The NASDAQ Capital Market. Among these requirements is the requirement that the Company’s stock trades at aminimum closing bid price of $1.00 per share. Our stock has recently and consistently traded below $1.00 per share, including closing bid prices below $1.00 pershare. On June 30, 2016, we received a deficiency letter from The NASDAQ Stock Market which provided us a grace period of 180 calendar days, or untilDecember 27, 2016, to regain compliance with the minimum bid price requirement, which would have required a closing bid price of at least $1.00 per share for aminimum of ten consecutive business days. We did not meet the minimum bid requirement prior to the expiration of the grace period on December 27, 2016, andon December 28, 2016, we received notice that NASDAQ granted us an additional 180-day grace period (until June 26, 2017) to regain compliance with theminimum bid price requirement. We may achieve compliance during this additional 180-day period if the closing bid price of our common stock is at least $1.00per share for a minimum of 10 consecutive business days before June 26, 2017. If we fail to regain compliance on or prior to June 26, 2017, our stock will besubject to delisting by NASDAQ. Additionally, if we fail to comply with any other continued listing standards of NASDAQ, our common stock will also be subjectto delisting. If that were to occur, our common stock would be subject to rules that impose additional sales practice requirements on broker-dealers who sell oursecurities. The additional burdens imposed upon broker-dealers by these requirements could discourage broker-dealers from effecting transactions in our commonstock. This would significantly and negatively affect the ability of investors to trade our securities and would significantly and negatively affect the value andliquidity of our common stock. These factors could contribute to lower prices and larger spreads in the bid and ask prices for our common stock. If we seek toimplement a reverse stock split in order to remain listed on The NASDAQ Capital Market, the announcement and/or implementation of a reverse stock split couldsignificantly negatively affect the price of our common stock.A portion of our revenue to date has been generated from government grants; continued availability of government grant funding is uncertain and contingenton 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 arereimbursed for certain expenses incurred in connection with our research and development activities, subject to our compliance with the specific requirements ofthe applicable grant, including rigorous documentation requirements. To the extent that we do not comply with these requirements, our expenses incurred may notbe reimbursed. Any of our existing grants or new grants that we may obtain in the future may be terminated or modified.21Table of ContentsOur ability to obtain grants or incentives from government entities in the future is subject to the availability of funds under applicable governmentprograms and approval of our applications to participate in such programs. The application process for these grants and other incentives is highly competitive. Wemay 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 levelsmay 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 weare 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.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, theseagencies may review our performance, cost structures and compliance with applicable laws, regulations and standards and the terms and conditions of the grant. Ifany 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 illegalactivities, we may be subject to civil and criminal penalties and administrative sanctions.Risks Relating to our Yield10 Bioscience Crop Science ProgramOur crop science product development cycle is lengthy and uncertain and will depend heavily on future collaborative partners.The technology and processes used in our crop science program and the application of our technology to enhance photosynthetic efficiency of crops are atan early stage of development. Research and development in the seed, agricultural biotechnology, and larger agriculture industries is expensive and prolonged andentails considerable uncertainty. Completion of our development work 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. Theindustry is highly concentrated and dominated by a small number of large players, which could impact efforts to form such collaborations. We may not besuccessful in establishing or maintaining suitable partnerships, and may not be able to negotiate collaboration agreements having terms 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 ornegatively impact the development and commercialization of our technologies.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 becommercialized. 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 effect 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 ourcontrol;•we or our future collaborators may be unable to obtain the requisite regulatory approvals for the seeds containing our traits;•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 tocommercialize such products; and•we may be unable to patent our traits in the necessary jurisdictions.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 thecrop science industry is expensive and prolonged, and entails considerable22Table of Contentsuncertainty. Because of the stringent product performance and safety criteria applied in development of crop science products, products currently underdevelopment may neither survive the development process nor ultimately receive the requisite regulatory approvals needed to market such products. Even whensuch approvals are obtained, there can be no assurance that a new product will be commercially successful. In addition, research undertaken by competitors maylead 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 collaborators are successful in developing commercial products that incorporate our traits, such products may not achieve commercialsuccess.Our strategy depends upon our or our collaborators’ ability to incorporate our traits into a wide range of crops in significant markets and geographies.Even if we or our collaborators are able to develop commercial products that incorporate our traits, any such products may not achieve commercial success for oneor 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 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 requiredprior to widespread deployment, and accordingly, it may take several growing seasons for farmers to adopt our or our collaborators’ products on alarge scale; and•we may not be able to produce high-quality seeds in sufficient amounts to meet demand.Our financial condition and results of operations could be materially and adversely affected if any of the above were to occur.Consumer and government resistance to genetically modified organisms may negatively affect the ability to commercialize crops containing our traits, as wellas our public image.Food and feed made from genetically modified seeds are not accepted by many consumers and in certain countries production of certain geneticallymodified crops is effectively prohibited, including throughout the European Union, due to concerns over such products’ effects on food safety and the environment.The high public profile of the biotechnology industry in food and feed production, and a lack of consumer acceptance of products to which we have devotedsubstantial resources, could have a negative impact on the commercial success of products that incorporate our traits and could materially and adversely affect ourability to obtain collaborations and to finance our crop science program. Further, we could incur substantial liability and/or legal expenses if there are claims thatgenetically-engineered crops damage the environment or contaminate other farm crops. This could distract our management and cause us to spend resourcesdefending against such claims.Actions by consumer groups and others may disrupt research and development or production of genetically modified seeds. In addition, some governmentauthorities have enacted, and others in the future might enact, regulations regarding genetically modified organisms, which may delay and limit or even prohibit thedevelopment and sale of such products.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 somemarkets.Seeds containing the traits that we develop must receive regulatory approval before they can be marketed, but we may not be able to obtain suchapprovals. Regulatory standards and procedures in the crop science industry are continuously changing, and responding to these changes and meeting existing andnew requirements will be costly and burdensome. Even if we are able to obtain approvals for the seeds containing the traits that we develop, changing regulatorystandards may affect our ability to maintain compliance with such regulatory standards.If ongoing or future field trials conducted by us or our collaborators are unsuccessful, we may be unable to complete the regulatory process for, orcommercialize, 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 productscontaining our traits. If our ongoing or future field trials, or those of our collaborators, are unsuccessful or produce inconsistent results or unanticipated adverseeffects on crops, or if we or our collaborators are unable23Table of Contentsto collect reliable data, regulatory review of products in development containing our traits could be delayed or commercialization of products in developmentcontaining 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 productcontaining our traits, and it may be necessary to collect data from different geographies to prove performance for customer adoption. Even in cases where fieldtrials 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, our collaborators conduct these field trials or we pay third parties, such as farmers, consultants, contractors, and universities, to conduct field trials onour behalf. Poor trial execution or data collection, failure to follow required agronomic practices, regulatory requirements, or mishandling of products indevelopment 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 orfloods, severe heat or frost, hail, tornadoes and hurricanes, uncommon pests and diseases, or acts of protest or vandalism. For example, if there was prolonged orpermanent disruption to the electricity, climate control, or water supply operating systems in our greenhouses or laboratories, the crops in which we or ourcollaborators are testing our traits and the samples we or our collaborators store in freezers, both of which are essential to our research and development activitiesincluding field tests, could be severely damaged or destroyed, adversely affecting these activities and thereby our business and results of operations. Unfavorableweather conditions including drought or excessive rain, or fluctuations in temperature, can also reduce both acreage planted and incidence, or timing of, certaincrop 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, andability to secure financing. Such factors outside of our control can create substantial volatility relating to our business and results of operations.Competition in traits and seeds is intense and requires continuous technological development, and, if we are unable to compete effectively, our financial resultswill suffer.We face significant competition in the markets in which we operate. The markets for traits and agricultural biotechnology products are intenselycompetitive and rapidly changing. In most segments of the seed and agricultural biotechnology market, the number of products available to consumers is steadilyincreasing as new products are introduced. At the same time, the expiration of patents covering existing products reduces the barriers to entry for competitors. Wemay be unable to compete successfully against our current and future competitors, which may result in price reductions, reduced margins and the inability toachieve market acceptance for products containing our traits. In addition, most of our competitors have substantially greater financial, marketing, sales,distribution, research and development, and technical resources than us, and some of our 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 technologiesbecome available. Our technologies may be rendered obsolete or uneconomical by technological advances or entirely different approaches developed by one ormore 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 and if we or our collaborators are unable to timely complete the regulatory process for our productsin development, our or our collaborators’ ability to market our traits could be delayed, prevented or limited.Our business is generally subject to two types of regulations: regulations that apply to how we and our collaborators operate and regulations that apply toproducts containing our traits. We apply for and maintain the regulatory permits necessary for our operations, particularly those covering our field trials, which weor our collaborators apply for and maintain regulatory approvals necessary for the commercialization of products containing our seed traits. Even if we and ourcollaborators make timely and appropriate applications for regulatory permits for our field trials, government delays in issuing such permits can significantly affectthe development timelines for our traits, particularly if the planting period for a crop growing season expires before the necessary permits are obtained. In most ofour key target markets, regulatory approvals must be received prior to the importation of genetically modified products. These regulatory processes are complex.For example, the U.S. federal government’s regulation of biotechnology includes, but is not limited to, the USDA, which regulates the import, field testing, andinterstate movement of genetically modified plants, and the FDA, which regulates foods derived from new plant varieties.In addition to regulation by the U.S. government, products containing our traits may be subject to regulation in each country in which such products aretested or sold. International regulations may vary from country to country and from those of the United States. The difference in regulations under U.S. law and thelaws of foreign countries may be significant and, in24Table of Contentsorder to comply with the laws of foreign countries, we may have to implement global changes to our products or business practices. Such changes may result inadditional expense to us and either reduce or delay product development or sales. Additionally, we or our collaborators may be required to obtain certifications orapprovals by foreign governments to test and sell the products in foreign countries.The regulatory process is expensive and time-consuming, and the time required to complete the process is difficult to predict and depends upon numerousfactors, including the substantial discretion of the regulatory authorities. We have not completed all phases of the regulatory process for any of our traits indevelopment. Our traits could require a significantly longer time to complete the regulatory process than expected, or may never gain approval, even if we and ourcollaborators 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 reviewpolicies during the development period of any of our traits, changes in, or the enactment of, additional regulations or statutes, or changes in regulatory reviewpractices for a submitted product application may cause a delay in obtaining approval or result in the rejection of an application for regulatory approval. Regulatoryapproval, if obtained, may be made subject to limitations on the intended uses for which we or our collaborators may market a product. These limitations couldadversely affect our potential revenues. Failure to comply with applicable regulatory requirements may, among other things, result in fines, suspensions ofregulatory approvals, product recalls, product seizures, operating restrictions, and criminal prosecution.Our work with the Smart Carbon Grid for Crops and the T3 Platform has identified promising potential targets for gene editing, and we believe that theseapproaches may be subject to less regulatory complexity in the U.S. during development and along the path to commercialization. Gene editing techniques,including CRISPR/Cas9, which involve making small targeted changes to the DNA of a target organism, have been of interest to the agricultural biotech industrybecause this approach is believed to have the potential to significantly reduce development costs and regulatory timelines for crop trait development and marketintroduction. Recent statements by the United States Department of Agriculture - Animal and Plant Health Inspection Service ("USDA-APHIS") regarding theregulatory path for genetically edited plants and mushrooms indicate that they will not be subject to regulations typically used for genetically modified crops (i.e.,they will not be considered “regulated articles”) if the modified organisms do not contain any remaining genetic elements from the procedure used for geneediting. While we believe that these industry examples suggest that crops that are gene edited may not be subject to certain GMO regulations in the U.S., wecannot assure you that this regulatory path will be found to apply to any of our seed yield traits or that the regulatory agencies will not change this approach to theregulation of genome editing or introduce new regulatory procedures applicable to such technologies.The products of third parties or the environment 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 grainor products produced from conventional or organic crops, could affect general public acceptance of these traits. Trace amounts of yield trait genes mayunintentionally be found outside our containment area in the products of third parties, which may result in negative publicity and claims of liability brought by suchthird parties against us. Furthermore, in the event of an unintended dissemination of our genetically engineered materials to the environment, we could be subject toclaims by multiple parties, including environmental advocacy groups, as well as governmental actions such as mandated crop destruction, product recalls oradditional stewardship practices and environmental cleanup or monitoring. The occurrence of any of these events could have a material adverse effect on ourbusiness and results of operations.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 tocomplete 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 thanif 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 anysuch engagement is terminated prematurely, we may be unable to conduct and complete our trials in the manner we anticipate. In addition, there is no guaranteethat 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 transferto us any regulatory information in a timely manner, fail25Table of Contentsto 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 manneror 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 ordelayed with additional costs incurred, or our data may be rejected by the applicable regulatory agencies. Ultimately, we are responsible for ensuring that each ofour field trials is conducted in accordance with the applicable protocol and with legal, regulatory and scientific standards, and our reliance on third parties does notrelieve us of our responsibilities.If our relationship with any of these third parties is terminated, we may be unable to enter into arrangements with alternative parties on commerciallyreasonable 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 delaysand potential inability to find a suitable replacement could materially and adversely impact our business.In addition, recently there has been an increasing trend towards consolidation in the agricultural biotechnology industry. Consolidation among ourcompetitors and third parties upon whom we rely could lead to a changing competitive landscape, capabilities, and strategic priorities among potential serviceproviders, 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 experiencenecessary 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. Our ability to attract and retain qualified employees may be affected by our efforts to manage cash usage, includingreductions in total cash compensation. The loss of key personnel or our inability to hire and retain personnel who have the required expertise and skills could havea material adverse effect on our research and development efforts, our business, and our ability to secure additional required financing.Risks Relating to Intellectual PropertyPatent 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 otherjurisdictions, as well as successfully enforcing and defending this intellectual property against third-party challenges. If we are not able to obtain or defend patentprotection for our technologies, then we will not be able to exclude competitors from developing or marketing such technologies, and this could negatively impactour 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 ormaintain profitability. Our currently issued patents relate to our historical business and have expiration dates ranging from 2020 through 2030. New outstandingpatent applications owned by or licensed to us, relating to crop yield improvements have filing dates ranging from 2013 through 2017.Our patent position involves complex legal and factual questions. Accordingly, we cannot predict the breadth of claims that may be allowed or enforced inour 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 claimsallowed 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, wemay be unable to protect certain of our intellectual property in the United States or in foreign countries. Foreign jurisdictions may not afford the same protectionsas 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 willchoose 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 incursubstantial 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. Anunfavorable outcome of any such litigation could have a material adverse effect on our business and results of operations.26Table of ContentsThird 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. Wecould incur substantial costs to challenge third party patents. If third parties assert claims against us or our customers alleging infringement of their patents or otherintellectual property rights, we could incur substantial costs and diversion of management resources in defending these claims, and the defense of these claimscould have a material adverse effect on our business. In addition, if we are unsuccessful in defending against these claims, these third parties may be awardedsubstantial damages, as well as injunctive or other equitable relief against us, which could effectively block our ability to make, use, sell, distribute, or market ourtechnologies 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 andcommercialization of our crop science technology. These licenses and options may not provide exclusive rights to use such intellectual property in all fields of usein 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 licenseagreements for optioned patent rights on acceptable terms, the academic institutions may offer such patent rights to third parties. If we fail to comply with ourobligations 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 thelicensed patents. Therefore, we cannot be certain that these patents and applications will be prosecuted, maintained and enforced in a manner consistent with thebest 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 aresult, the government may have certain rights, or march‑in 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 numberof more established companies may also pursue strategies to license or acquire crop science technologies that we may consider attractive. These establishedcompanies may have a competitive advantage over us due to their size, cash resources and greater development and commercialization capabilities. Any failure onour 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 acquirerelevant 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 meanfewer suitable opportunities for us as well as higher acquisition or licensing costs. If we are unable to successfully obtain rights to suitable crop sciencetechnologies on reasonable terms, or at all, our business and financial condition could suffer.The intellectual property landscape around genome editing technology, such as CRISPR/Cas9, is highly dynamic and uncertain, and any resolution of thisuncertainty could have a material adverse effect on our business.The field of genome editing, especially in the area of CRISPR/Cas9 technology, is still in its infancy, and no products using this technology have reachedthe market. We are currently negotiating a license for work in the CRISPR/Cas9 field in order to demonstrate the utility of our yield trait genes in this field. Due tothe intense research and development that is taking place by several companies, including us and our competitors, in this field, the intellectual property landscape isin flux, and it may remain uncertain for the coming years. There has been, and may continue to be, significant intellectual property related litigation andproceedings relating to this area in the future. If we obtain a license to certain patent rights27Table of Contentsusing the CRISPR/Cas9 technology, and it is later determined that such patent rights are invalid or owned by other parties, this could have a material adverse effecton 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 orobtainable. However, trade secrets are difficult to protect. Litigating a claim that a third party had illegally obtained and was using our trade secrets would beexpensive and time consuming, and the outcome would be unpredictable. Moreover, if our competitors independently develop similar knowledge, methods andknow-how, it will be difficult for us to enforce our rights and our business could be harmed.Risks Relating to Owning our Common StockRaising additional funds may cause dilution to our existing stockholders, restrict our operations or require us to relinquish rights to our technologies.If we raise additional funds through equity offerings or offerings of equity-linked securities, including warrants or convertible debt securities, we expectthat our existing stockholders will experience significant dilution, and the terms of such securities may include liquidation or other preferences that adversely affectyour rights as a stockholder. Debt financing, if available, may subject us to restrictive covenants that could limit our flexibility in conducting future businessactivities, including covenants limiting or restricting our ability to incur additional debt, dispose of assets or make capital expenditures. We may also incur ongoinginterest expense and be required to grant a security interest in our assets in connection with any debt issuance. If we raise additional funds through strategicpartnerships or licensing agreements with third parties, we may have to relinquish valuable rights to our technologies or grant licenses on terms that are notfavorable to us.A material weakness was identified in our internal control over financial reporting, which could impact our business and financial results.Our internal control over financial reporting may not prevent or detect misstatements because of its inherent limitations, including the possibility ofhuman error, the circumvention or overriding of controls, or fraud. Even effective internal controls can provide only reasonable assurance with respect to thepreparation and fair presentation of financial statements. If we fail to maintain the adequacy of our internal controls, including any failure to implement requirednew or improved controls, or if we experience difficulties in their implementation, our business and financial results could be harmed and we could fail to meet ourfinancial reporting obligations. For example, in connection with the evaluation of the effectiveness of our internal control over financial reporting as of December31, 2016, we determined that our controls over accounting for stock based compensation expense did not operate effectively. Specifically, our procedures did notoperate as designed to validate the calculation for stock based compensation expense resulting from an option award modification. We determined that thisconstitutes a material weakness.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 withadequate liquidity. Our stock price may be extremely volatile, and our stockholders could lose a significant part of their investment.Trading volume in our stock is low and an active trading market for shares of our common stock may not be sustained on a consistent basis. The publictrading 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;28Table of Contents•announcements or the absence of announcements by us, or our competitors, regarding acquisitions, new products, significant contracts, commercialrelationships 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;•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 manytechnology companies have experienced wide fluctuations that have often been unrelated to the operating performance of those companies. Any negative change inthe 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 of our common stock.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 changesin 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 incontrol that stockholders may consider favorable, including transactions in which our stockholders might otherwise receive a premium for their shares of ourcommon 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 prohibits a publicly-held Delaware corporation from engaging in a businesscombination 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%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 businesscombination 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 ofour common stock. They could also deter potential acquirers of our Company, thereby reducing the likelihood that our stockholders could receive a premium fortheir common stock in an acquisition.Concentration of ownership among our existing officers, directors and principal stockholders may prevent other stockholders from influencing significantcorporate decisions and depress our stock price.Based on the number of shares outstanding as of March 17, 2017, our officers, directors and stockholders who hold at least 5% of our stock beneficiallyown a combined total of approximately 69.7% of our outstanding common stock, including shares of common stock subject to stock options and warrants that arecurrently exercisable or are exercisable within 60 days after March 17, 2017. If these officers, directors, and principal stockholders or a group of our principalstockholders act together, they will be able to exert a significant degree of influence over our management and affairs and control matters requiring stockholderapproval, including the election of directors and approval of mergers, business combinations or other significant transactions. The interests of one or more of thesestockholders may not always coincide with our interests or the interests of other stockholders. For instance, officers, directors, and principal stockholders, actingtogether, could cause us to enter into transactions or agreements that we would not otherwise consider. Similarly, this concentration of ownership may have theeffect of delaying or preventing a change in control of our company otherwise favored by our other stockholders. As of March 17, 2017, Jack W. Schuler andWilliam P. Scully beneficially owned approximately 47.7% and approximately 10.3% of our common stock, respectively.ITEM 1B. UNRESOLVED STAFF COMMENTSNone.29Table of ContentsITEM 2. PROPERTIESWe do not own any real property. On January 20, 2016, we entered into a lease agreement pursuant to which we lease approximately 30,000 square feet ofoffice and research and development space located at 19 Presidential Way, Woburn, Massachusetts. The lease began on June 1, 2016 and will end on November30, 2026. Under the terms of the lease agreement, the landlord paid $889 for tenant improvements to the facility and paid an additional $444 for tenantimprovements that result in increased rental payments by the Company. Current and non-current portions of the lease incentive obligations related to the landlord’scontributions toward the cost of tenant improvements are recorded within accrued expenses and long-term lease incentive obligation, respectively, in theCompany's consolidated balance sheet contained herein. The lease incentive obligation will be amortized to rent expense over the lease term. As of December 31,2016, the Company has a total remaining lease incentive obligation of $1,259 . Pursuant to the lease, the Company also pays certain taxes and operating costsassociated with the premises during the term of the lease. To secure the lease, the Company provided the landlord with a deposit in the form of a letter of credit inthe amount of $307.On October 10, 2016, the Company entered into a sublease agreement with a subsidiary of CJ CheilJedang Corporation ("CJ") for CJ's sublease ofapproximately 10,000 square feet of the Company's Woburn facility. The subleased space was determined to be in excess of the Company's needs as a result of itsrecent strategic shift and the related restructuring of its operations. The sublease is coterminous with the Company's master lease. CJ will pay rent and operatingexpenses equal to approximately one-third of the amounts payable to the landlord by the Company, as adjusted from time-to-time in accordance with the terms ofthe master lease. In October 2016, CJ provided the Company with a security deposit of $103 in the form of an irrevocable letter of credit.We also lease approximately 13,700 square feet of office and laboratory space at 650 Suffolk Street, Lowell, Massachusetts. Our lease for this facilityexpires in May 2020, with an option to renew for one five-year period. We are currently working with a commercial real estate broker to locate a subtenant for thisspace. Our wholly-owned subsidiary, Metabolix Oilseeds, Inc. ("MOI"), located in Saskatoon, Saskatchewan, Canada, leases approximately 4,100 square feet ofoffice, laboratory and greenhouse space. MOI's leases for these facilities expire on July 31, 2017 and September 30, 2017. We expect to renew these leases prior totheir expiration.ITEM 3. LEGAL PROCEEDINGSFrom time to time, the Company may be subject to legal proceedings and claims in the ordinary course of business.

SELECTED CONSOLIDATED FINANCIAL DATANot applicableITEM 7. MANAGEMENT'S DISCUSSION AND ANALYSIS OF FINANCIAL CONDITION AND RESULTS OF OPERATIONSThe following discussion and analysis should be read in conjunction with the Consolidated Financial Statements and Notes thereto included in thisAnnual Report on Form 10-K. All dollar amounts are stated in thousands.OverviewYield10 Bioscience, Inc. is an agricultural bioscience company focusing on the development of step-change increases in food and feed crop yield toenhance global food security. According to a United Nations report, food production must be increased by over 70 percent in the next 35 years to feed the growingglobal population, which is expected to increase from 7 billion to more than 9.6 billion by 2050. Yield10 is focused on new agricultural biotechnology approaches,using two proprietary discovery platforms, to improve fundamental crop yield through enhanced photosynthetic carbon capture and increased carbon utilizationefficiency where the additional captured carbon is targeted to increase seed yield. These platforms are based on the principle that plants which capture and utilizecarbon more efficiently generate benefits in the form of more robust crops with increased seed yield. Yield10 is working to develop, translate and demonstrate thecommercial value of new genetically engineered yield trait genes and to identify genome editing targets for improved crop performance in several key food andfeed crops, including canola, soybean, rice and corn. Yield10 Bioscience is headquartered in Woburn, Massachusetts and has an additional agricultural sciencefacility with greenhouses in Saskatoon, Saskatchewan, Canada.Collaborative ArrangementsWe are not currently participating in any collaborative arrangements. Our historical strategy for collaborative arrangements has been to retain substantialparticipation in the future economic value of our technology while receiving current cash payments to offset research and development costs and working capitalneeds. By their nature, our collaborative agreements have been complex, containing multiple elements covering a variety of present and future activities. Our near-term strategic business plan includes the identification of third parties who will enter into collaborative arrangements with us to further research and developmentof new agricultural biotechnology to advance increases in crop yield.Government GrantsAs of December 31, 2016, proceeds of $1,268 remain available under our U.S. government grants. This includes amounts for reimbursement to oursubcontractors, as well as reimbursement for our employees’ time, benefits and other expenses related to future performance. The status of our government grants is as follows: Program Title FundingAgency TotalGovernmentFunds Total received throughDecember 31, 2016 Remaining amountavailable as ofDecember 31, 2016 Contract/GrantExpiration Production of High Oil, Transgene Free Camelina SativaPlants through Genome Editing Department ofEnergy $1,997 $841 $1,156 September 2017 Subcontract from NC State University (NCSU) projectfunded by DOE ARPA-E entitled "Jet Fuel fromCamelina Sativa: A Systems Approach" Department ofEnergy 276 164 112 March 2017 Renewable Enhanced Feedstocks For Advanced BiofuelsAnd Bioproducts ("REFABB") Department ofEnergy 6,000 6,000 — February 2016 Subcontract from University of Massachusetts (Amherst)project funded by ARPA-E entitled “Development of aDedicated High Value Biofuels Crop” Department ofEnergy 663 663 — December 2015 Total $8,936 $7,668 $1,268 32Table of ContentsCritical Accounting Estimates and JudgmentsOur consolidated financial statements are prepared in accordance with accounting principles generally accepted in the United States of America. Thepreparation of these consolidated financial statements requires us to make estimates and assumptions that affect the reported amounts of assets, liabilities, revenue,costs and expenses, and related disclosures. We evaluate our estimates and assumptions on an ongoing basis. Our actual results may differ from these estimates.We believe that our significant accounting policies, which are described in Note 2 to our consolidated financial statements, involve a degree of judgmentand complexity. Accordingly, we believe that the specific accounting policies described below are the most critical to aid in fully understanding and evaluating ourconsolidated financial condition and results of operations.Revenue RecognitionWe recognize revenue in accordance with accounting standards on revenue recognition. Our principal sources of revenue are government research grantsand research and development payments that are primarily derived from collaborative agreements with other companies.We recognize government grants as revenue because the grants are central to the Company's ongoing crop science program. Revenue is earned as researchexpenses related to the grants are incurred. Revenue earned on government grants, but not yet invoiced as of the balance sheet date, are recorded as unbilledreceivables in the accompanying consolidated balance sheets for the years ended December 31, 2016 and December 31, 2015. Funds received from governmentgrants in advance of work being performed are recorded as deferred revenue until earned.Stock-Based CompensationThe accounting standards for stock-based compensation require that all stock-based awards to employees be recognized as an expense in the consolidatedfinancial statements and that such expense be measured based on the fair value of the award.Determining the appropriate fair value model and calculating the fair value of stock-based payment awards requires the use of highly subjectiveassumptions, including the expected life of the stock-based payment awards and stock price volatility. We use the Black-Scholes option-pricing model to value ourservice-based option grants and determine the related compensation expense. When we issue restricted stock units containing market and performance vestingconditions, we estimate the fair value and derived service period of these awards using a Monte Carlo valuation model. Generally, we recognize the fair value ofstock awards evenly over their vesting periods provided the employee, director or non-employee receiving the award continues to meet continuing serviceconditions. The assumptions used in calculating the fair value of stock-based awards represent management's best estimates, but the estimates involve inherentuncertainties and the application of management judgment. See Note 10 to the consolidated financial statements for further discussion on the key assumptions usedto determine the fair values of option grants pursuant to the Black-Scholes option pricing model.Discontinued OperationsA discontinued operation is a component of an entity that has either been disposed of, or that is classified as held for sale, which represents a separatemajor line of business or geographical area of operations and is part of a single coordinated plan to dispose of a separate major line of business or geographical areaof operations. In accordance with the accounting guidance regarding the presentation of discontinued operations, the activity of our biopolymers component hasbeen reclassified as a discontinued operation for the years ended December 31, 2016 and 2015. In July 2016, the Company announced a strategic restructuring planin which Yield10 Bioscience became its core business which resulted in the sale of its biopolymer operations in September 2016.Results of OperationsThe consolidated financial statements for the two years ending December 31, 2016, have been presented to reflect the former biopolymer operations ofYield10 Bioscience as a discontinued operation.33Table of ContentsComparison of the Years Ended December 31, 2016 and 2015Revenue Year endedDecember 31, 2016 2015 Change Grant revenue $1,159 $1,350 $(191) Total revenue from continuing operations was $1,159 and $1,350 for the years ended December 31, 2016 and 2015 , respectively, and was derived solelyfrom our research grants. The $191 decrease in grant revenue for the year ended December 31, 2016, is primarily the result of the REFABB grant that ended inFebruary 2016. During the year ended December 31, 2016, we did not recognize any further revenue from the REFABB grant. During the year ended December31, 2015, $1,028 was recognized from this grant. No revenue was recognized from the REFABB grant during 2016. Partially offsetting this decrease wereincreased grant revenues of $1,126 recognized from our two Camelina grants.We anticipate that grant revenue will increase over the next twelve months as we continue to make progress on our current outstanding grants whileseeking to obtain and apply resources to additional government grants during 2017.Expenses Year endedDecember 31, 2016 2015 Change Research and development expenses $5,670 $6,602 $(932) General and administrative expenses 5,737 7,217 (1,480) Total costs and expense $11,407 $13,819 $(2,412) Research and Development ExpensesResearch and development expenses from continuing operations were $5,670 and $6,602 for the years ended December 31, 2016 and 2015 , respectively.The decrease of $932 was primarily due to a decrease in employee compensation and related benefit expenses. Employee compensation and related benefitexpenses were $2,624 and $3,247 for the years ended December 31, 2016 and 2015, respectively. The decrease of $623 is primarily attributable to decreases inheadcount and the elimination of the 2016 bonuses as a result of our strategic restructuring and ongoing efforts to conserve cash. Research facility expenses alsodecreased by $586 from $2,421 during the year ended December 31, 2015 to $1,835 for the year ended December 31, 2016, primarily as a result of the Company'smove to its new Woburn, Massachusetts facility. Partially offsetting these expense reductions was a $209 increase in sponsored research expense as a result of theCompany's Camelina field test and payments made to a third party for its work in support of one of the Camelina government grants. We expect research and development expenses from continuing operations to decrease during 2017 as a result of our receiving the full-year benefit fromour restructuring efforts completed during the second half of 2016 and our close monitoring of available cash resources.General and Administrative ExpensesGeneral and administrative expenses from continuing operations were $5,737 and $7,217 for the fiscal years ended December 31, 2016 and 2015,respectively. The decrease of $1,480 was primarily attributable to decreases in employee compensation and related benefits expenses. Employee compensation andrelated benefits expenses decreased by $1,169 from $3,830 for the year ended December 31, 2015 to $2,661 for the year ended December 31, 2016. The decreasewas primarily attributable to the Company's elimination of its 2016 bonuses and a net $810 decrease in stock compensation expense arising out of our restructuringactivities and management changes completed during the second half of 2016. In addition, professional fees decreased by $154 from $1,387 during the year endedDecember 31, 2015 to $1,233 during the year ended December 31, 2016, primarily as a result of our receiving the current year benefit of lower auditing feesresulting from the Company's change in auditing firms.34Table of ContentsWe expect our general and administrative expenses from continuing operations to decrease during 2017 as a result of our restructuring efforts completedduring the second half of 2016 and our close monitoring of available cash resources.Other Income (Net) Year endedDecember 31, 2016 2015 Change Total other income (expense), net $(38) $29 $(67) Other income (expense), net, reflects net expense of $38 and net income of $29 for the years ended December 31, 2016 and 2015, respectively. The netexpense for 2016 is the result of imputed interest charges recorded in connection with the Company's early termination of a manufacturing agreement with a thirdparty, partially offset by investment income. Other income, net, shown for 2015, is primarily the result of income from the Company's investment in money marketfunds and realized net gains from foreign currency translation.Income (Loss) from Discontinued Operations, before income taxIn July 2016, our Board of Directors approved a restructuring plan under which Yield10 Bioscience became the Company's core business with a focus ondeveloping disruptive technologies for step-change improvements in crop yield to enhance global food security. As a result of this strategic shift, during 2016, wecompleted the sale of certain biopolymer intellectual property, equipment and inventory to an affiliate of CJ CheilJedang Corporation ("CJ"). The $10,000 purchaseprice paid by CJ was primarily for the acquisition of intellectual property, including the Company’s PHA strains, patent rights, know-how and its rights, title andinterest in certain license agreements. None of this intellectual property was previously capitalized on the Company’s balance sheet, resulting in a gain on the saleof approximately $9,868, net of equipment sold. The sale of our biopolymer assets generated income before income tax of $2,682 from discontinued operations forthe year ended December 31, 2016, compared to a loss from discontinued operations before income tax of $11,241 for the year ended December 31, 2015. Theyear-over-year change of $13,923 is the result of recognizing a net gain on the sale of biopolymer assets of $9,833 to CJ during the year ended December 31, 2016and the 2016 reduction in biopolymer operating costs as a result of the Company's discontinuation of its biopolymer operations.Income Tax BenefitFor the year ended December 31, 2016, the Company recognized an income tax benefit within continuing operations of $1,097 and tax expense indiscontinued operations of $1,097 related to taxable income generated during the year as a result of the sale of biopolymer assets to CJ as discussed above. For theyear ended December 31, 2015, the Company did no t recognize any tax benefit or expense due to its loss position and valuation allowance.Liquidity and Capital ResourcesCurrently, we require cash to fund our working capital needs, to purchase capital assets, to pay our operating lease obligations and other operating costs.The primary sources of our liquidity have historically included equity financings, government research grants and income earned on cash and short-terminvestments.Since our inception, we have incurred significant expenses related to our research, development and commercialization efforts. With the exception of2012, when we recognized $38,885 of deferred revenue from a terminated joint venture, the Company has recorded losses since its initial founding, including itsfiscal year ended December 31, 2016. As of December 31, 2016, we had an accumulated deficit of $333,357 . Our total unrestricted cash and cash equivalents as ofDecember 31, 2016, were $7,309 as compared to $12,269 at December 31, 2015. As of December 31, 2016, we had no outstanding debt.Our cash and cash equivalents at December 31, 2016, were held for working capital purposes. As of December 31, 2016, we had restricted cash of $432 .Restricted cash consists of $307 held in connection with the lease agreement for our Woburn, Massachusetts facility and $125 held in connection with ourcorporate credit card program.35Table of ContentsInvestments are made in accordance with our corporate investment policy, as approved by our Board of Directors. The primary objective of this policy isto preserve principal and investments are limited to high quality corporate debt, U.S. Treasury bills and notes, money market funds, bank debt obligations,municipal debt obligations and asset-backed securities. The policy establishes maturity limits, concentration limits, and liquidity requirements. As of December 31,2016, we were in compliance with this policy.We anticipate that our current cash resources will be sufficient to fund operations and meet our obligations, including our restructuring obligations, whendue, into the fourth quarter of 2017. This forecast of cash resources is forward-looking information that involves risks and uncertainties, and the actual amount ofexpenses could vary materially and adversely as a result of a number of factors. We have adopted the new guidance of ASU 2014-15, Presentation of FinancialStatements-Going Concern (Subtopic 205-40) in order to determine whether there is substantial doubt about the Company's ability to continue as a going concernfor one year after the date its financial statements are issued. The Company's ability to continue operations after its current cash resources are exhausted depends onits ability to obtain additional financing through, among other sources, public or private equity financing, secured or unsecured debt financing, equity or debtbridge financing, additional government research grants or collaborative arrangements with third parties, as to which no assurances can be given. We do not knowwhether additional financing will be available on terms favorable or acceptable to the Company when needed, if at all. If adequate additional funds are notavailable when required, or if we are unsuccessful in entering collaborative arrangements for further research, we may be forced to curtail our research efforts,explore strategic alternatives and/or wind down our operations and pursue options for liquidating our remaining assets, including intellectual property andequipment. Based on our cash forecast, we have determined that the Company's present capital resources are not sufficient to fund our planned operations for atwelve month period, and therefore, raise substantial doubt about its ability to continue as a going concern.Although we have $20,000 of availability under our equity facility with Aspire, market conditions likely will limit the extent to which the Company candraw on this facility. We continue to face significant challenges and uncertainties and, as a result, our available capital resources may be consumed more rapidlythan currently expected due to (a) changes we may make to the business that affect ongoing operating expenses; (b) changes we may make to our business strategy;(c) changes in our research and development spending plans; and (d) other items affecting our forecasted level of expenditures and use of cash resources. Ourpresent capital resources will not be sufficient to fund our planned operations for a twelve month period, and therefore, raise substantial doubt about our ability tocontinue as a going concern.During 2016, we completed a strategic restructuring of our operations to focus on the Yield10 Bioscience business. We reduce staffing levels to twentyfull-time employees and incurred restructuring costs for contract termination and employee post-termination benefits of approximately $3,525 which are primarilyreflected in discontinued operations within the Company's statement of operations. At December 31, 2016, $2,048 of these restructuring charges remainoutstanding and are required to be paid out through May 2018. We currently anticipate that we will use approximately $7,500 - $8,000 of cash during 2017,including anticipated payments for restructuring costs. This estimated cash usage for operations is significantly less than cash used for operations of $14,700 and$21,863 during the years ended December 31, 2016 and 2015, respectively, and the reduction is primarily the result of our restructuring efforts.On October 7, 2015, we entered into a common stock purchase agreement with Aspire under which Aspire is committed to purchase, at our direction, upto an aggregate of $20,000 of shares of our common stock over a 30 month period that will end on May 8, 2018. Common stock may be sold from time to time atthe Company’s option under pricing formulas based on prevailing market prices around the time of each sale. The extent to which we utilize the facility withAspire as a source of funding will depend on a number of factors, including the prevailing market price of our common stock, the volume of trading in our commonstock and the extent to which we are able to secure funds from other sources. The purchase agreement contains limitations on the number of shares that we mayissue to Aspire. Additionally, we and Aspire may not effect any sales of shares of our common stock under the purchase agreement during the continuance of anevent of default or on any trading day that the closing sale price of our common stock is less than $0.50 per share. At December 31, 2016, the market price for theCompany's common stock was below $0.50 and the full $20,000 remained available under the purchase agreement with Aspire. On December 30, 2016, the marketprice for our common stock closed at $0.35 per share.We will need additional capital to fully implement our business, operating and development plans and to support our capital needs. The timing, structureand vehicles for obtaining future financing are under consideration, but there can be no assurance that such financing efforts will be successful. If we do not receiveadditional funding during 2017, we may be forced to wind down our business, or have to delay, scale back or otherwise modify our business plans, research anddevelopment activities and other operations, and/or seek strategic alternatives.36Table of ContentsIf we issue equity or debt securities to raise additional funds, (i) the Company may incur fees associated with such issuance, (ii) our existing stockholderswill experience dilution from the issuance of new equity securities, (iii) the Company may incur ongoing interest expense and be required to grant a securityinterest in Company assets in connection with any debt issuance, and (iv) the new equity or debt securities may have rights, preferences and privileges senior tothose of our existing stockholders. In addition, utilization of our net operating loss and research and development credit carryforwards may be subject to significantannual limitations under Section 382 of the Internal Revenue Code of 1986 due to ownership changes resulting from future equity financing transactions. If weraise additional funds through collaboration, licensing or other similar arrangements, it may be necessary to relinquish valuable rights to our potential products orproprietary technologies, or grant licenses on terms that are not favorable to the Company.Net cash used for operating activities was $14,700 during the year ended December 31, 2016, compared to net cash used by operating activities during2015 of $21,863 . Net cash used by operations during the year ended December 31, 2016, primarily reflects the net loss of $7,604 , the add-back of the gain on thesale of the Company's discontinued biopolymer assets, including certain property and equipment, totaling $9,833 that is shown within cash proceeds underinvesting activities, the payment of 2015 performance bonuses during early 2016 of $1,665, partially offset by non-cash expenses, including stock-basedcompensation expense of $848 , depreciation expense of $515 , inventory impairment write-downs totaling $199 , the Company's 401(k) stock matchingcontribution expense of $281 and the settlement of certain restructuring costs through transfers of manufacturing equipment and the issuance of Yield10 Biosciencecommon stock.The following are the non-cash operating items and investing items related to discontinued operations for the years ended December 31, 2016 andDecember 31, 2015. Year Ended December 31, 2016 2015Non-cash operating items: Depreciation$326 $147Charge for 401(k) company common stock match$118 $167Stock-based compensation$217 $663Inventory impairment$199 $209Non-cash restructuring expense paid through stock and equipment$196 $—Gain on sale of discontinued operation and property and equipment$(9,833) $(33)Net cash of $9,752 was provided by investing activities during the year ended December 31, 2016, compared to net cash used by investing activitiesduring 2015 of $614 . Net cash provided by investing activities during the year ended December 31, 2016, was primarily the result of proceeds received from thesale of biopolymer assets of $10,317 and a net decrease in restricted cash of $187 , partially offset by purchases of property and equipment to outfit the newWoburn, Massachusetts facility of $752 .No cash was used or provided by financing activities during the year ended December 31, 2016. During the year ended December 31, 2015, the Companycompleted a $15,000 financing from a private placement of equity securities and received $14,703 , net of issuance costs of $297.Off-Balance Sheet ArrangementsAs of December 31, 2016, we had no off-balance sheet arrangements as defined in Item 303(a)(4) of the Securities and Exchange Commission'sRegulation S-K.Related Party TransactionsSee Note 8 to our consolidated financial statements for a full description of our related party transactions.37Table of ContentsRecent Accounting Standards ChangesFor a discussion of recent accounting standards please read Note 2, Summary of Significant Accounting Policies, to our consolidated financial statementsincluded in this report.ITEM 7A.

CHANGES IN AND DISAGREEMENTS WITH ACCOUNTANTS ON ACCOUNTING AND FINANCIAL DISCLOSUREBased upon the recommendation of our Audit Committee, PricewaterhouseCoopers LLP was dismissed as the Company's independent registered publicaccounting firm and RSM US LLP was appointed as its independent registered public accounting firm for the fiscal year ending December 31, 2016. That changewas reported by the Company in a Current Report on Form 8-K dated January 3, 2017, filed with the SEC on January 5, 2017.ITEM 9A. CONTROLS AND PROCEDURESEffectiveness of Disclosure Controls and ProceduresWe have established controls and procedures (as such term is defined in Rules 13a-15(e) and 15d-15(e) under the Securities Act of 1934, as amended (the"Exchange Act")) that are designed to ensure that information required to be disclosed in reports that we file or submit under the Exchange Act is recorded,processed, summarized and reported within the time periods specified in the rules and forms of the SEC and to ensure that information required to be disclosed isaccumulated and communicated to management, including our Chief Executive Officer (principal executive officer) and Chief Accounting Officer (principalfinancial officer), to allow timely decisions regarding disclosure. Under the supervision and with the participation of our management, including our ChiefExecutive Officer and Chief Accounting Officer, we conducted an evaluation of the effectiveness of our disclosure controls and procedures as of December 31,2016. Based on this evaluation, our Chief Executive Officer and Chief Accounting Officer have concluded that our disclosure controls and procedures were noteffective at a reasonable assurance level as of December 31, 2016 due to a material weakness in internal control over financial reporting, as further describedbelow.Management's Annual Report on Internal Control over Financial ReportingOur management is responsible for establishing and maintaining adequate internal control over financial reporting. Under the supervision and with theparticipation of our management, including our Chief Executive Officer and Chief Accounting Officer, we conducted an evaluation of the effectiveness of ourinternal control over financial reporting as of December 31, 2016, based on the criteria set forth by the Committee of Sponsoring Organizations of the TreadwayCommission (COSO) in Internal Control—Integrated Framework (2013). Based on this evaluation, management concluded that the material weakness in internalcontrol over financial reporting described below existed as of December 31, 2016.A material weakness is a deficiency, or a combination of deficiencies, in internal control over financial reporting, such that there is a reasonablepossibility that a material misstatement of the Company’s annual or interim financial statements will not be prevented or detected on a timely basis.We did not maintain effective internal control over the accounting for stock based compensation expense. Specifically, our control over validating theaccuracy of stock based compensation expense resulting from an option award38Table of Contentsmodification that occurred during the Company's fourth fiscal quarter did not operate as designed, and this resulted in an audit adjustment reflected as a reductionin general and administrative operating expense within continuing operations within our consolidated financial statements as of and for the year ended December31, 2016. This level of adjustment is material to the Company's financial statements. Accordingly, our management determined that this control deficiencyconstitutes a material weakness.We have concluded that the material weakness described above existed as of December 31, 2016. As a result, management has concluded that theCompany did not maintain effective internal control over financial reporting as of December 31, 2016, based on the COSO criteria described above.Remediation PlansThe Company will undertake steps during its first quarter of 2017 to remediate the causes of the internal control failure related to the Company'saccounting for the stock award modification. Specifically, we will perform the following steps:•Our accounting staff responsible for preparing and reviewing stock based compensation will complete renewed training in the accounting for stockaward modifications as provided by current accounting standards, including ASC Topic 718, Compensation – Stock Compensation;•We will assess whether our licensed stock compensation software, as used by us, was a contributing cause of the error, and if limitations exist in thecalculation stock compensation expense for stock award modifications, we will develop alternative procedures to ensure the accuracy of ourcalculations;•We will undertake additional staff training to ensure that we correctly utilize the software application for future stock award modifications isappropriate;•We will develop and implement enhanced policies, procedures and controls related to the calculation of stock based compensation when a stockaward modification occurs.We are committed to maintaining a strong internal control environment, and believe that these remediation efforts will represent significant improvements in ourcontrol environment. In the history of the company, stock award modifications have rarely occurred, if at all, before the ones that were recorded this past quarter. Inthe event Company modifies other stock awards, we will apply our enhanced procedures and controls to ensure a similar error does not occur.Changes in Internal Control over Financial ReportingWith the exception of the material weakness related to the calculation of stock compensation expense discussed above, there have been no changes in ourinternal control over financial reporting identified in connection with the evaluation required by Rule 13a-15(d) of the Exchange Act that occurred during our lastfiscal quarter in the period covered by this Annual Report on Form 10-K that have materially affected, or are reasonably likely to materially affect, our internalcontrol over financial reporting.ITEM 9B.

We believe we have allocated our compensation among base salary and short- and long-term incentive compensationopportunities in such a way as to not encourage excessive or inappropriate risk-taking by our executives and other employees.

CERTAIN RELATIONSHIPS AND RELATED TRANSACTIONS, AND DIRECTOR INDEPENDENCEThe charter of the Nominating and Corporate Governance Committee provides that the committee shall conduct an appropriate review of all related partytransactions (including those required to be disclosed pursuant to Item 404 of Regulation S-K) for potential conflict of interest situations on an ongoing basis, andthe approval of that committee shall be required for all such transactions.Also, under the Company's Code of Business Conduct, any transaction or relationship that reasonably could be expected to give rise to a conflict ofinterest involving an employee must be reported promptly to the Company's Chief Accounting Officer, who has been designated as the Company's ComplianceOfficer. The Compliance Officer may notify the Board of Directors or a committee thereof as he deems appropriate. Actual or potential conflicts of interestinvolving a director, executive officer or the Compliance Officer must be disclosed directly to the Chairman of the Board of Directors.The transactions set forth below were approved by a majority of the Board of Directors, including a majority of the independent and disinterestedmembers of the Board of Directors. The Company believes that it has executed all of the transactions set forth below on terms no less favorable to us than couldhave been obtained from unaffiliated third parties.The Company previously licensed certain technology to Tepha, Inc., a related party, for use in medical applications. During May 2016, the Companyentered into an amendment to its license agreement with Tepha, in which the Company received a lump sum payment of $2,000 in consideration for an earlybuyout of all future royalties under the agreement and the licensing of two additional production strains and related intellectual property that was fully delivered toTepha during 2016. The Company recognized $2,272 and $578 of license and royalty revenue from Tepha for the years ended December 31, 2016 and 2015 ,respectively. During 2016, the Company also received $11 from Tepha in connection with their purchase of certain laboratory equipment previously used in theCompany's biopolymer operations. Dr. Sinskey, a member of our Board of Directors, serves on the board of directors of Tepha. Dr. Peoples, Dr. Sinskey and Dr.Snell are stockholders of Tepha, and the Company owns 648,149 shares of Tepha's Series A redeemable convertible preferred stock. We believe that the terms ofthe transactions with Tepha were no less favorable to us than license agreements that might be entered into with an independent third party.Independence of Members of the Board of DirectorsThe Board of Directors has determined that each of the Company's non-employee directors (Mr. Kellogg, Dr. Sinskey, Dr. Hamilton, and Mr. VanNostrand) is independent within the meaning of the director independence standards of The NASDAQ Stock Market, LLC. ("NASDAQ") and the Securities andExchange Commission ("SEC"), including rules under the Securities Exchange Act of 1934, as amended (the "Exchange Act"). Furthermore, the Board ofDirectors has determined that each member of each of the Audit, Compensation and Nominating and Corporate Governance committees of the Board of Directorsis independent within the meaning of the director independence standards of NASDAQ and the SEC, and that each member of the Audit Committee meets theheightened director independence standards for audit committee members as required by the SEC. In evaluating the independence of the directors, the Boardconsidered the relationship of Dr. Sinskey as a stockholder and members of the board of directors of Tepha, Inc. The Board determined that these relationships didnot impair the independence of Dr. Sinskey. See "Certain Relationships and Related Person Transactions."At least annually, a committee of the Board of Directors evaluates all relationships between the Company and each director in light of relevant facts andcircumstances for the purpose of determining whether a material relationship exists that might signal a potential conflict of interest or otherwise interfere with suchdirector's ability to satisfy his responsibilities as an independent director.ITEM 14.

ContentsYIELD10 BIOSCIENCE, INC.(formerly known as Metabolix, Inc.)NOTES TO THE CONSOLIDATED FINANCIAL STATEMENTS(In thousands, except for share and per share amounts)1. Nature of Business and Basis of PresentationYield10 Bioscience, Inc. was founded as Metabolix, Inc. in 1992 and changed its name in January 2017. Yield10 Bioscience is an agricultural biosciencecompany focusing on the development of new technologies to enable step-change increases in crop yield to enhance global food security. Yield10 is using twoproprietary advanced biotechnology trait gene discovery platforms to improve fundamental crop yield through enhanced photosynthetic carbon capture andincreased carbon utilization efficiency to increase seed yield. These platforms are based on the principle that plants which capture and utilize carbon moreefficiently will enable more robust crops capable of increased seed yield. Yield10 is working to translate and demonstrate the commercial value of novel yield traitgenes it has identified in major crops and to identify additional genome editing targets for improved crop performance in several key food and feed crops, includingcanola, soybean, rice and corn. Yield10 Bioscience is headquartered in Woburn, Massachusetts and has an additional agricultural science facility with greenhouseslocated in Saskatoon, Saskatchewan, Canada.The accompanying consolidated financial statements have been prepared on a basis which assumes that the Company will continue as a going concern andwhich contemplates the realization of assets and satisfaction of liabilities and commitments in the normal course of business. With the exception of 2012, when theCompany recognized $38,885 of deferred revenue from a terminated joint venture, the Company has recorded losses since its initial founding, including its fiscalyear ending December 31, 2016. During 2016, the Company completed a strategic restructuring under which Yield10 Bioscience became its core business. Inconnection with the restructuring, the Company discontinued its pilot biopolymer production and other biopolymer operations, sold substantially all of itsbiopolymer assets to CJ CheilJedang Corporation ("CJ") for a total purchase price of $10,000 and reduced staffing levels to approximately twenty full-timeemployees as of December 31, 2016, in order to focus on crop science activities and significantly reduce the Company's cash burn rate used in operations. During2016, the Company recorded restructuring charges of $3,525 and as of December 31, 2016, restructuring obligations of $2,048 remain outstanding with variouspayment due dates through May 2018.As of December 31, 2016, the Company held unrestricted cash and cash equivalents of $7,309 . The Company anticipates current cash resources will besufficient to fund operations and meet its obligations, including its restructuring obligations, when due into the fourth quarter of 2017. This forecast of cashresources is forward-looking information that involves risks and uncertainties, and the actual amount of expenses could vary materially and adversely as a result ofa number of factors. The Company has evaluated the new guidance of ASU 2014-15, Presentation of Financial Statements-Going Concern (Subtopic 205-40) inorder to determine whether there is substantial doubt about its ability to continue as a going concern for one year after the date its financial statements are issued.The Company's ability to continue operations after its current cash resources are exhausted depends on its ability to obtain additional financing through, amongother sources, public or private equity financing, secured or unsecured debt financing, equity or debt bridge financing, additional government research grants orcollaborative arrangements with third parties, as to which no assurances can be given. Management does not know whether additional financing will be availableon terms favorable or acceptable to the Company when needed, if at all. If adequate additional funds are not available when required, or if the Company isunsuccessful in entering collaborative arrangements for further research, management may be forced to curtail the Company's research efforts, explore strategicalternatives and/or wind down its operations, pursue options for liquidating its remaining assets, including intellectual property and equipment and/or seek strategicalternatives. Based on the cash forecast, management has determined that the Company's present capital resources are not sufficient to fund its planned operationsfor a twelve month period from the date that the financial statements are issued, and therefore, raise substantial doubt about its ability to continue as a goingconcern. During 2015, the Company entered into a common stock purchase agreement with Aspire Capital Fund, LLC ("Aspire"). Under terms of the agreement,Aspire committed to purchase up to $20,000 of Yield10 Bioscience common stock over a 30 month period that will end on May 8, 2018. Common stock may besold from time to time at the Company’s option under pricing formulas based on prevailing market prices around the time of each sale. The purchase agreementcontains limitations on the number of shares that the Company may sell to Aspire. Additionally, the Company and Aspire may not effect any sales of shares of itscommon stock under the purchase agreement during the continuance of an event of default orF- 9Table of ContentsYIELD10 BIOSCIENCE, INC.(formerly known as Metabolix, Inc.)NOTES TO THE CONSOLIDATED FINANCIAL STATEMENTS(In thousands, except for share and per share amounts)on any trading day that the closing sale price of its common stock is less than $0.50 per share. At December 31, 2016, the market price for the Company's commonstock was below $0.50 , and although the full $20,000 remained available under the purchase agreement with Aspire, market conditions likely limit the extentwhich the Company can draw on this facility.If the Company issues equity or debt securities to raise additional funds, (i) the Company may incur fees associated with such issuance, (ii) its existingstockholders may experience dilution from the issuance of new equity securities, (iii) theCompany may incur ongoing interest expense and be required to grant a security interest in Company assets in connection with any debt issuance, and (iv) the newequity or debt securities may have rights, preferences and privileges senior to those of the Company’s existing stockholders. In addition, utilization of theCompany’s net operating loss and research and development credit carryforwards may be subject to significant annual limitations under Section 382 of the InternalRevenue Code of 1986 due to ownership changes resulting from equity financing transactions. If the Company raises additional funds through collaboration,licensing or other similar arrangements, it may be necessary to relinquish valuable rights to its potential products or proprietary technologies, or grant licenses onterms that are not favorable to the Company.On June 30, 2016, the Company received a Notice of Delisting from The Nasdaq Stock Market LLC ("Nasdaq") as a result of the Company's bid price forthe previous 30 consecutive business days closing below the minimum $1.00 per share requirement for continued listing on The Nasdaq Capital Market underNasdaq Listing Rule 5810(a)(2). In accordance with Nasdaq Listing Rule 5810(c)(3)(A), the Company was provided with an initial period of 180 calendar days, oruntil December 27, 2016, to regain compliance. On December 28, 2016, the Company received a second notice that Nasdaq had granted the Company an additional180 days (until June 26, 2017) to regain compliance with Nasdaq's $1.00 per share minimum bid price. The Company is considering actions that it may take inorder to regain compliance with this continued listing requirement.2. Summary of Significant Accounting PoliciesPrinciples of ConsolidationThe Company's consolidated financial statements are prepared in accordance with accounting principles generally accepted in the United States ofAmerica. The consolidated financial statements include the accounts of the Company and its wholly-owned subsidiaries. All intercompany transactions wereeliminated, including transactions with its Canadian subsidiary, Metabolix Oilseeds, Inc. On September 16, 2016, the Company completed the sale of itsbiopolymer intellectual property and certain equipment and inventory to an affiliate of CJ in a transaction that met the requirements for discontinued operationsreporting in accordance with ASU No. 2014-08, Reporting Discontinued Operations and Disclosures of Disposals of Components of an Entity . The consolidatedfinancial statements for each of the two years ending December 31, 2016, have been presented to reflect the Company's biopolymer operation as a discontinuedoperation.Use of EstimatesThe preparation of financial statements in conformity with accounting principles generally accepted in the United States of America ("GAAP") requiresmanagement to make estimates and assumptions that affect the reported amounts of assets and liabilities and the disclosure of contingent assets and liabilities at thedate of the financial statements and the reported amounts of revenues and expenses during the reporting periods. Actual results could differ from those estimates.Cash and Cash EquivalentsThe Company considers all highly liquid investments purchased with an original maturity date of ninety days or less at the date of purchase to be cashequivalents.InvestmentsThe Company considers all investments purchased with an original maturity date of ninety days or more at the date of purchase and a maturity date of oneyear or less at the balance sheet date to be short-term investments. All otherF- 10Table of ContentsYIELD10 BIOSCIENCE, INC.(formerly known as Metabolix, Inc.)NOTES TO THE CONSOLIDATED FINANCIAL STATEMENTS(In thousands, except for share and per share amounts)investments are classified as long-term. The Company held no short or long-term investments at December 31, 2016 or December 31, 2015.Unrealized gains and temporary losses on investments are included in accumulated other comprehensive income (loss) as a separate component ofstockholders' equity. Realized gains and losses, dividends, interest income and declines in value judged to be other-than-temporary credit losses are included inother income (expense). Any premium or discount arising at purchase is amortized and/or accreted to interest income.Restricted CashThe Company had restricted cash in the amount of $432 and $619 at December 31, 2016, and December 31, 2015, respectively. At December 31, 2016,restricted cash consists of $307 held in connection with the lease agreement for the Company's Woburn, Massachusetts facility and $125 held in connection with itscorporate credit card program.Deferred Equity Financing CostsThe Company entered into a common stock purchase agreement in 2015 with Aspire Capital in which Aspire committed to purchase up to $20,000 of theCompany's common stock over a 30-month period (see Note 9). Offering costs incurred to establish this agreement have been recorded as deferred equity financingcosts in the accompanying consolidated balance sheet at December 31, 2016 and December 31, 2015. These costs will be charged to additional paid-in-capital asshares are issued under the agreement. In the event it is determined that no additional shares will be issued, any remaining deferred equity offering costs will berecognized as expense at that time.Foreign Currency TranslationForeign denominated assets and liabilities of the Company's wholly-owned foreign subsidiaries are translated into U.S. dollars at the prevailing exchangerates in effect on the balance sheet date. Revenues and expenses are translated at average exchange rates prevailing during the period. Any resulting translationgains or losses are recorded in accumulated other comprehensive income (loss) in the consolidated balance sheet. When the Company dissolves, sells orsubstantially sells all of the assets of a consolidated foreign subsidiary, the cumulative translation gain or loss of that subsidiary is released from comprehensiveincome (loss) and included within its consolidated statement of operations during the fiscal period when the dissolution or sale occurs.Comprehensive Income (Loss)Comprehensive income (loss) is comprised of net income (loss) and certain changes in stockholders' equity that are excluded from net income (loss). TheCompany includes unrealized gains and losses on marketable securities and foreign currency translation adjustments in other comprehensive income (loss).Concentration of Credit RiskFinancial instruments that potentially subject the Company to concentrations of credit risk primarily consist of cash and cash equivalents and accountsreceivable. The Company has historically invested its cash equivalents in highly rated money market funds, corporate debt, federal agency notes and U.S. treasurynotes. Investments are acquired in accordance with the Company's investment policy which establishes a concentration limit per issuer. At December 31, 2016, theCompany's cash equivalents were invested solely in money market funds.The Company's receivables related to government grants are believed to have a low risk of default. At December 31, 2016 , the Company's accounts andunbilled receivables of $188 are substantially all from research grants with the U.S. government under which the Company serves as either the primary contractoror as a subcontractor. At December 31, 2015 , the Company's accounts and unbilled receivables included $156 or 29% from government research grants.F- 11Table of ContentsYIELD10 BIOSCIENCE, INC.(formerly known as Metabolix, Inc.)NOTES TO THE CONSOLIDATED FINANCIAL STATEMENTS(In thousands, except for share and per share amounts)Fair Value MeasurementsThe carrying amounts of the Company's financial instruments as of December 31, 2016 and 2015 , which include cash equivalents, accounts receivable,unbilled receivables, receivables due from related parties, accounts payable, and accrued expenses, approximate their fair values due to the short-term nature ofthese instruments. See Note 4 for further discussion on fair value measurements.Segment InformationThe accounting guidance for segment reporting establishes standards for reporting information on operating segments in annual financial statements. TheCompany is an agricultural bioscience company operating in one segment, which is the development of technologies to produce step-change improvements in cropyield for food and feed crops. The Company's chief operating decision-maker does not manage any part of the Company separately, and the allocation of resourcesand assessment of performance are based on the Company's consolidated operating results. As of December 31, 2016 , and December 31, 2015, less than 10% ofthe Company's combined total assets were located outside of the United States. In addition, the reported net income (loss) outside of the United States was less than10% of the combined net income (loss) of the consolidated Company.Property and EquipmentProperty and equipment are stated at cost less accumulated depreciation. Repairs and maintenance are charged to operations as incurred. Depreciation iscomputed using the straight-line method over the estimated useful lives of the assets once they are placed in service as follows:Asset Description Estimated Useful LifeEquipment 2.5 - 3 yearsFurniture and Fixtures 5Software 3Leasehold improvements Shorter of useful life or term of leaseThe Company records incentive payments received from its landlords as deferred rent and amortizes these amounts as reductions to lease expense over thelease term.Impairment of Long-Lived AssetsLong-lived assets, such as property and equipment, are reviewed for impairment whenever events or changes in circumstances indicate that the carryingamount of an asset may not be recoverable. The guidance further requires that companies recognize an impairment loss only if the carrying amount of a long-livedasset is not recoverable based on its undiscounted future cash flows and measure an impairment loss as the difference between the carrying amount and fair valueof the asset.Revenue RecognitionThe Company's principal source of continuing revenue is from its government research grants in which it serves as either the primary contractor or as asubcontractor. These contracts grants are considered an ongoing major and central operation of the Company's business. Revenue is earned as research expensesrelated to the grants are incurred. Revenue earned on government grants, but not yet invoiced as of the balance sheet date, are recorded as unbilled receivables inthe accompanying consolidated balance sheets for the years ended December 31, 2016 and December 31, 2015. Funds received from government grants in advanceof work being performed are recorded as deferred revenue until earned.F- 12Table of ContentsYIELD10 BIOSCIENCE, INC.(formerly known as Metabolix, Inc.)NOTES TO THE CONSOLIDATED FINANCIAL STATEMENTS(In thousands, except for share and per share amounts)Research and DevelopmentAll costs associated with internal research and development are expensed as incurred. Research and development expenses include, among others, directcosts for salaries, employee benefits, subcontractors, product trials, facility related expenses, depreciation, and stock-based compensation. Costs related to revenue-producing contracts and government grants are recorded as research and development expenses.General and Administrative ExpensesThe Company's general and administrative expense includes costs for salaries, employee benefits, facilities expenses, consulting fees, travel expenses,depreciation expenses, and office related expenses incurred to support the administrative operations of the Company.Intellectual Property CostsThe Company includes all costs associated with the prosecution and maintenance of patents within general and administrative expenses in theconsolidated statement of operations.Stock-Based CompensationAll share-based payments to employees, members of the Board of Directors and non-employees are recognized in the statement of operations based ontheir fair values. For employees and members of the Company's Board of Directors, who receive nearly all of our stock awards, stock compensation expense isrecognized based on the grant-date fair value of the award, adjusted for estimated forfeitures, and is recognized on a straight-line basis over the period duringwhich the recipient is required to provide service in exchange for the award. See Note 10 for a description of the types of stock-based awards granted, thecompensation expense related to such awards and detail of equity-based awards outstanding.Basic and Diluted Net Loss per ShareBasic net income (loss) per share is computed by dividing net income (loss) by the weighted-average number of common shares outstanding. Diluted netloss per share is computed by dividing net income by the weighted-average number of dilutive common shares outstanding during the period. Diluted sharesoutstanding is calculated by adding to the weighted shares outstanding any potential (unissued) shares of common stock from outstanding stock options andwarrants based on the treasury stock method, as well as weighted shares outstanding of any potential (unissued) shares of common stock from restricted stock units.In periods when a net loss is reported, all common stock equivalents are excluded from the calculation because they would have an anti-dilutive effect, meaning theloss per share would be reduced. Therefore, in periods when a loss is reported, there is no difference in basic and dilutive loss per share. Common stock equivalentsinclude stock options, restricted stock awards and warrants.The Company follows the two-class method when computing net loss per share, when it has issued shares that meet the definition of participatingsecurities. The two-class method determines net loss per share for each class of common and participating securities according to dividends declared oraccumulated and participating rights in undistributed earnings. The two-class method requires income available to common stockholders for the period to beallocated between common and participating securities based on their respective rights to receive dividends, as if all income for the period has been distributed orlosses to be allocated if they are contractually required to fund losses. There were no amounts allocated to participating securities during each of the two yearsended December 31, 2016, as the Company was in a loss position and had no shares that met the definition of participating securities outstanding at December 31,2016 and December 31, 2015.The number of shares of potentially dilutive common stock presented on a weighted average basis, related to options, restricted stock units and warrants(prior to consideration of the treasury stock method) that were excluded from theF- 13Table of ContentsYIELD10 BIOSCIENCE, INC.(formerly known as Metabolix, Inc.)NOTES TO THE CONSOLIDATED FINANCIAL STATEMENTS(In thousands, except for share and per share amounts)calculation of dilutive shares since the inclusion of such shares would be anti-dilutive for the years ended December 31, 2016 and 2015 , respectively, are shownbelow: Year Ended December 31, 2016 2015 Options 898,711 943,197 Restricted stock awards 707,581 946,074 Warrants 3,933,000 2,144,293 Total 5,539,292 4,033,564 In July 2016, the Board of Directors of the Company approved a strategic restructuring plan under which Yield10 Bioscience became its core business with afocus on developing disruptive technologies for step-change improvements in crop yield to enhance global food security. In connection with this restructuring, theCompany discontinued its biopolymer operations. The Company's consolidated statement of operations for the years ending December 31, 2016 and 2015, includedin this annual report have been prepared to present basic and diluted earnings per share from continuing and discontinued operations.Income TaxesThe Company accounts for income taxes using the asset and liability method, which requires the recognition of deferred tax assets and liabilities for theexpected future tax consequences of events that have been recognized in the consolidated financial statements or in the Company's tax returns. Under this method,deferred tax assets and liabilities are determined based on the difference between the financial statement and tax basis of assets and liabilities using enacted taxrates in effect for the year in which the differences are expected to reverse. A valuation allowance is provided to reduce the deferred tax asset to a level which,more likely than not, will be realized. See Note 11 for further discussion of income taxes. The Company had no amounts recorded for any unrecognized taxbenefits as of December 31, 2016 and 2015.The Company accounts for uncertain tax positions using a "more-likely-than-not" threshold for recognizing and resolving uncertain tax positions. Theevaluation of uncertain tax positions is based on factors that include, but are not limited to, changes in tax law, the measurement of tax positions taken or expectedto be taken in tax returns, the effective settlement of matters subject to audit, new audit activity and changes in facts or circumstances related to a tax position. Theprovision for income taxes includes the effects of any resulting tax reserves or unrecognized tax benefits that are considered appropriate as well as the related netinterest and penalties, if any. The Company evaluates uncertain tax positions on a quarterly basis and adjusts the level of the liability to reflect any subsequentchanges in the relevant facts surrounding the uncertain positions.Restructuring ChargesIn July 2016, the Company announced a strategic restructuring under which Yield10 Bioscience became its core business and its biopolymer operationswere discontinued. The Company records estimated restructuring charges for employee severance and contract termination costs as a current period expense asthose costs become contractually fixed, probable and estimable. The long and short-term obligations associated with these charges is reduced or adjusted aspayments are made or the Company's estimates are revised.Recent Accounting Standards ChangesFrom time to time, new accounting pronouncements are issued by the Financial Accounting Standards Board ("FASB") or other standard setting bodiesthat we adopt as of the specified effective date.In August 2014, the FASB issued ASU 2014-15, Presentation of Financial Statements-Going Concern (Subtopic 205-40) . The new guidance addressesmanagement’s responsibility to evaluate whether there is substantial doubt about anF- 14Table of ContentsYIELD10 BIOSCIENCE, INC.(formerly known as Metabolix, Inc.)NOTES TO THE CONSOLIDATED FINANCIAL STATEMENTS(In thousands, except for share and per share amounts)entity’s ability to continue as a going concern for one year after the date that the financial statements are issued and to provide related footnote disclosures.Management’s evaluation should be based on relevant conditions and events that are known and reasonably knowable at the date that the financial statements areissued. This guidance should reduce diversity in the timing and content of footnote disclosures. The amendments in this update apply to all entities and areeffective for the annual period ending after December 15, 2016, and for annual periods and interim periods thereafter. The Company adopted ASU 2014-15 for itsfiscal year ending December 31, 2016. The adoption impacted presentation and disclosure only and did not have an impact on the Company's financial position orresults of operations.In August 2016, the FASB issued ASU No. 2016-15, Statement of Cash Flows (Topic 230): Classification of Certain Cash Receipts and Cash Payments . The newstandard clarifies certain aspects of the statement of cash flows, including the classification of debt prepayment or debt extinguishment costs, settlement of zero-coupon debt instruments or other debt instruments with coupon interest rates that are insignificant in relation to the effective interest rate of the borrowing,contingent consideration payments made after a business combination, proceeds from the settlement of insurance claims, proceeds from the settlement ofcorporate-owned life insurance policies, distributions received from equity method investees and beneficial interests in securitization transactions. The newstandard also clarifies that an entity should determine each separately identifiable source or use within the cash receipts and cash payments on the basis of thenature of the underlying cash flows. In situations in which cash receipts and payments have aspects of more than one class of cash flows and cannot be separated bysource or use, the appropriate classification should depend on the activity that is likely to be the predominant source or use of cash flows for the item. The newstandard will be effective for the Company on January 1, 2018. The Company is in the process of evaluating the impact of this new guidance.In June 2016, the FASB issued ASU No. 2016-13, Financial Instruments - Credit Losses (Topic 326): Measurement of Credit Losses on Financial Instruments .The new standard changes the impairment model for most financial assets and certain other instruments. Under the new standard, entities holding financial assetsand net investment in leases that are not accounted for at fair value through net income are to be presented at the net amount expected to be collected. An allowancefor credit losses will be a valuation account that will be deducted from the amortized cost basis of the financial asset to present the net carrying value at the amountexpected to be collected on the financial asset. The new standard will be effective for us on January 1, 2020. The Company is in the process of evaluating theimpact of this new guidance.In March 2016, the FASB issued ASU No. 2016-06, Derivatives and Hedging (Topic 815): Contingent Put and Call Options in Debt Instruments . Thenew standard simplifies the embedded derivative analysis for debt instruments containing contingent call or put options by removing the requirement to assesswhether a contingent event is related to interest rates or credit risks. The new standard will be effective for us on January 1, 2017. The adoption of this standard isnot expected to have an impact on our financial position or results of operations.In March 2016, the FASB issued ASU No. 2016-07, Investments - Equity Method and Joint Ventures (Topic 323): Simplifying the Transition to the EquityMethod of Accounting . The new standard eliminates the requirement that when an investment qualifies for use of the equity method as a result of an increase in thelevel of ownership interest or degree of influence, an adjustment must be made to the investment, results of operations and retained earnings retroactively on a step-by-step basis as if the equity method had been in effect during all previous periods that the investment had been held. The new standard will be effective for theCompany on January 1, 2017. The adoption of this standard is not expected to have a material impact on our financial position or results of operations.In March 2016, the FASB issued ASU No. 2016-09, Compensation - Stock Compensation (Topic 718) : Improvements to Employee Share-Based PaymentAccounting . The new standard involves several aspects of the accounting for share-based payment transactions, including the income tax consequences,classification of awards as either equity or liabilities and classification on the statement of cash flows. The new standard will be effective for the Company onJanuary 1, 2017. The Company is in the process of evaluating the impact of this new guidance.In February 2016, the FASB issued ASU 2016-02, Leases (Topic 842). The new standard requires that all lessees recognize the assets and liabilities thatarise from leases on the balance sheet and disclose qualitative and quantitative information about its leasing arrangements. The new standard will be effective forus on January 1, 2019. The Company is in the process of evaluating the impact of this new guidance.F- 15Table of ContentsYIELD10 BIOSCIENCE, INC.(formerly known as Metabolix, Inc.)NOTES TO THE CONSOLIDATED FINANCIAL STATEMENTS(In thousands, except for share and per share amounts)In January 2016, the FASB issued ASU No. 2016-01, Financial Instruments - Overall (Subtopic 825-10): Recognition and Measurement of FinancialAssets and Financial Liabilities . The new standard amends certain aspects of accounting and disclosure requirements of financial instruments, including therequirement that equity investments with readily determinable fair values be measured at fair value with changes in fair value recognized in our results ofoperations. The new standard does not apply to investments accounted for under the equity method of accounting or those that result in consolidation of theinvestee. Equity investments that do not have readily determinable fair values may be measured at fair value or at cost minus impairment adjusted for changes inobservable prices. A financial liability that is measured at fair value in accordance with the fair value option is required to be presented separately in othercomprehensive income for the portion of the total change in the fair value resulting from change in the instrument-specific credit risk. In addition, a valuationallowance should be evaluated on deferred tax assets related to available-for-sale debt securities in combination with other deferred tax assets. The new standardwill be effective for us on January 1, 2018. The Company is in the process of evaluating the impact of this new guidance.In May 2014, the FASB issued Accounting Standards Update ("ASU") No. 2014-09, Revenue from Contracts with Customers (Topic 606). The ASU isthe result of a joint project by the FASB and the International Accounting Standards Board ("IASB") to clarify the principles for recognizing revenue and todevelop a common revenue standard for GAAP and International Financial Reporting Standards ("IFRS") that would: remove inconsistencies and weaknesses,provide a more robust framework for addressing revenue issues, improve comparability of revenue recognition practices across entities, jurisdictions, industries,and capital markets, improve disclosure requirements and resulting financial statements, and simplify the presentation of financial statements. The core principle ofthe new guidance is that an entity should recognize revenue to depict the transfer of promised goods or services in an amount that reflects the consideration towhich the entity expects to be entitled in exchange for those goods or services. The ASU is effective for annual reporting periods beginning after December 15,2016. Early adoption is not permitted. On July 9, 2015, the FASB voted to delay the effective date of the new revenue standard by one year, but to permit entities tochoose to adopt the standard as of the original date. We have begun to evaluate the effect the new revenue standard will have on our consolidated financialstatements and related disclosures, but have not completed our evaluation and implementation process. We intend to complete the process during 2017 and adoptthe standard on January 1, 2018, using the full retrospective adoption transition method. The adoption of this standard is not expected to have a material impact onour financial position or results of operations.3. Significant CollaborationsThe Company follows the accounting guidance for collaborative arrangements which requires that certain transactions between collaborators be recordedin the income statement on either a gross or net basis, depending on the characteristics of the collaboration relationship, and provides for enhanced disclosure ofcollaborative relationships. The Company evaluates its collaborative agreements for proper income statement classification based on the nature of the underlyingactivity.Yield10 Bioscience is not currently participating in any collaborative arrangements. The Company's historic strategy for collaborative arrangements hasbeen to retain substantial participation in the future economic value of its technology while receiving current cash payments to offset research and developmentcosts and working capital needs. By their nature, the Company's collaborative agreements have been complex, containing multiple elements covering a variety ofpresent and future activities.F- 164. Fair Value MeasurementsThe Company has certain financial assets recorded at fair value which have been classified as Level 1 within the fair value hierarchy as described in theaccounting standards for fair value measurements. Fair value is the price that would be received from the sale of an asset or the price paid to transfer a liability inan orderly transaction between independent market participants at the measurement date. Fair values determined by Level 1 inputs utilize observable data such asquoted prices in active markets for identical instruments. Fair values determined by Level 2 inputs utilize data points other than quoted prices in active markets thatare observable either directly or indirectly. Fair values determined by Level 3 inputs utilize unobservable data points in which there is little or no market data,which require the reporting entity to develop its own assumptions. The fair value hierarchy level is determined by the lowest level of significant input. AtDecember 31, 2016 and 2015, the Company did not own any Level 2 or Level 3 financial assets or liabilities and there were no transfers of financial assets orliabilities between category levels for the years ended December 31, 2016 and December 31, 2015.The Company's assets are measured at fair value on a recurring basis. The balance of Level 1 assets as of December 31, 2016 and December 31, 2015were $1,018 and $8,013 , respectively, and for both years the assets were in money market funds classified in cash and cash equivalents.5.

The Company is not currently awareof any such proceedings or claims that it believes will have, individually or in the aggregate, a material adverse effect on the business, financial condition or theresults of operations.GuaranteesAs of December 31, 2016 and 2015, the Company did not have significant liabilities recorded for guarantees.The Company enters into indemnification provisions under various agreements with other companies in the ordinary course of business, typically withbusiness partners, contractors, and customers. Under these provisions, the Company generally indemnifies and holds harmless the indemnified party for lossessuffered or incurred by the indemnified party as a result of its activities. These indemnification provisions generally survive termination of the underlyingagreement. The maximum potential amount of future payments the Company could be required to make under these indemnification provisions is unlimited.However, to date Yield10 Bioscience has not incurred material costs to defend lawsuits or settle claims related to these indemnification provisions. As a result, theestimated fair value of these agreements is minimal. Accordingly, the Company has no liabilities recorded for these agreements as of December 31,2016 and December 31, 2015.F- 19Table of ContentsYIELD10 BIOSCIENCE, INC.(formerly known as Metabolix, Inc.)NOTES TO THE CONSOLIDATED FINANCIAL STATEMENTS(In thousands, except for share and per share amounts)8.

See Note 15.9. Capital StockCommon StockIn connection with the wind down of its biopolymer operations, the Company ceased pilot production of biopolymer material at its third-party biopolymerproduction facilities. On September 19, 2016, the Company entered into an early termination agreement with the owner-operator of one of the biopolymerproduction facilities. As part of the consideration for the early termination, the Company issued 275,000 unregistered shares of Yield10 common stock.On October 7, 2015, the Company entered into a common stock purchase agreement with Aspire Capital Fund, LLC. Under the terms of the agreement,Aspire committed to purchase up to an aggregate of $20,000 of the Company's common stock over a 30 month period that will end on May 8, 2018. Common stockmay be sold from time to time at the Company’s direction under pricing formulas based on prevailing market prices around the time of each sale. The purchaseagreement contains limitations on the number of shares that the Company may sell to Aspire. Additionally, the Company and Aspire may not effect any sales ofshares of the Company's common stock under the purchase agreement during the continuance of an event of default or on any trading day that the closing sale priceof its common stock is less than $0.50 per share. Upon execution of the purchase agreement, the Company issued 300,000 shares of its common stock to Aspirewith a fair value of $450 , as a commitment fee. In addition, the Company incurred $172 of additional costs in connection with the Aspire facility, which alongwith the fair value of the common stock has been recorded as deferred equity financing costs in the accompanying consolidated balance sheet at December 31,2016 and December 31, 2015. These costs will be charged to additional paid-in-capital as shares are issued to Aspire. In the event it is determined no additionalshares will be issued under the purchase agreement, any remaining deferred equity offering costs will be expensed at such time. At December 31, 2016, the full$20,000 under the purchase agreement remains available for sale to Aspire.On June 19, 2015, the Company completed a private placement of its securities. Proceeds received from the transaction were $14,703 , net of issuancecosts of $297 . Investors participating in the transaction purchased a total of 4,370,000 shares of common stock at a price of $3.32 per share and warrants with apurchase price of $0.125 per warrant to purchase up to an aggregate of 3,933,000 additional shares of common stock. The warrants have a four -year term and areimmediately exercisable at a price of $3.98 per share. The Company has determined that the warrants should be recorded within equity as additional paid-in capital.F- 20Table of ContentsYIELD10 BIOSCIENCE, INC.(formerly known as Metabolix, Inc.)NOTES TO THE CONSOLIDATED FINANCIAL STATEMENTS(In thousands, except for share and per share amounts)Preferred StockThe Company's certificate of incorporation, as amended and restated, authorizes it to issue up to 5,000,000 shares of $0.01 par value preferred stock. Asof December 31, 2016 and December 31, 2015, no preferred stock was issued or outstanding.10. Stock-Based CompensationThe Company adopted a stock plan in 2006 (the "2006 Plan"), which provided for the granting of incentive stock options, nonqualified stock options,stock appreciation rights, deferred stock awards, restricted stock awards, unrestricted stock awards, cash-based awards and dividend equivalent rights. In October2014, the 2006 Plan was terminated and the Company adopted a new plan (the "2014 Plan"). No further grants or awards were subsequently made under the 2006Plan. A total of 1,467,076 options have been awarded from the 2006 Plan and as of December 31, 2016 , 482,314 of these options remain outstanding and eligiblefor future exercise.The 2014 Plan provides for the granting of incentive stock options, nonqualified stock options, stock appreciation rights, deferred stock awards, restrictedstock awards, unrestricted stock awards, cash-based awards and dividend equivalent rights. A total of 5,401,118 options have been awarded from the 2014 Plan andas of December 31, 2016 , 5,376,786 of these options remain outstanding and eligible for future exercise. A total of 1,192,023 restricted stock awards have beenawarded from the 2014 Plan and as of December 31, 2016, 261,283 of these restricted stock awards are unvested and outstanding.Expense Information for Employee Stock AwardsThe Company recognized stock-based compensation expense, related to employee stock awards, including awards to non-employees and members of theBoard of Directors, of $848 and $2,128 for the years ended December 31, 2016 and 2015 , respectively. At December 31, 2016 , there was approximately $1,828 ofstock-based compensation expense, net of estimated forfeitures, related to unvested awards not yet recognized which is expected to be recognized over a weightedaverage period of 1.81 years.Stock OptionsOptions granted under the 2006 Plan and the 2014 Plan (the "Plans") generally vest ratably over periods of one to four years from the date of hire for newemployees, or date of award for existing employees, or date of commencement of services with the Company for nonemployees, and generally expire ten yearsfrom the date of issuance. The Company's policy is to issue new shares upon the exercise of stock options.On October 26, 2016, the Company's Compensation Committee granted stock options for a total of 4,560,000 shares to employees who remained with theCompany after the Company's restructuring was completed. Of this amount, options for 1,750,000 shares were contingent until December 21, 2016, whenshareholder approval of certain amendments to the 2014 Plan was obtained, at which point they were no longer contingent. Each option has an exercise price pershare equal to the fair market value of the Company's common stock on the date of grant, vests in four equal semi-annual installments at a rate of 25% perinstallment over two years, and has a term of ten years from the date of grant.On November 4, 2016, the Company's former chief executive officer ("CEO"), was granted stock options for 750,000 shares upon the execution ofseparation and release agreements relating to the termination of his employment with the Company. These options have an exercise price per share equal to the fairmarket value of the Company's common stock on the date of grant, were fully vested on the date of grant, became exercisable on the effective date of the releaseagreement, and will remain exercisable through December 19, 2023. The Company recognized the full fair value of this award as stock compensation expense in itsfourth fiscal quarter ending December 31, 2016.In December 2013, the Company's Board of Directors granted a non-qualified stock option award for the purchase of 191,667 shares of common stock toits former CEO in connection with his agreement to serve as a member of theF- 21Table of ContentsYIELD10 BIOSCIENCE, INC.(formerly known as Metabolix, Inc.)NOTES TO THE CONSOLIDATED FINANCIAL STATEMENTS(In thousands, except for share and per share amounts)Company's Board and to accept employment as its President and Chief Executive Officer. Upon execution of his separation agreement on November 4, 2016, the143,750 remaining unvested stock options under this award became fully vested. The Company accounted for this vesting as an award modification and recordedthe new fair value of the remaining options as expense during the Company's fourth fiscal quarter.A summary of the activity related to the shares of common stock covered by outstanding options is as follows: Number ofShares Weighted AverageExercise Price Remaining ContractualTerm(in years) Aggregate IntrinsicValueBalance at December 31, 2015 904,133 $26.58 Granted 5,365,000 0.53 Exercised — — Forfeited (42,410) 6.68 Expired (175,956) 32.44 Balance at December 31, 2016 6,050,767 3.45 8.82 $—Vested and expected to vest at December 31, 2016 5,780,598 3.58 8.77 —Exercisable at December 31, 2016 1,422,694 12.85 5.60 —The weighted average grant date fair value per share of options granted during fiscal years 2016 and 2015 , was $0.31 , and $2.61 , respectively. Nooptions were exercised during 2016 and 2015, and therefore the intrinsic value for exercised options during the two years was not applicable. The weighted averageremaining contractual term for options outstanding as of December 31, 2016 was 8.8 years .For the years ended December 31, 2016 , and 2015 , the Company determined the fair value of stock options using the Black-Scholes option pricingmodel with the following assumptions for option grants, respectively: Year Ended December 31, 2016 2015Expected dividend yield — —Risk-free rate 1.24% - 2.04% 1.32% - 1.69%Expected option term (in years) 5.4-5.7 5.5-5.9Volatility 93% - 96% 88% - 91%The Company determined its volatility assumption based on actual market price fluctuations experienced during its trading history. The risk-free interestrate used for each grant is equal to the U.S. Treasury yield curve in effect at the time of grant for instruments with a term similar to the expected life of the relatedoption. The expected term of the options is based upon evaluation of historical and expected future exercise behavior.The stock price volatility and expected terms utilized in the calculation involve management's best estimates at that time, both of which impact the fairvalue of the option calculated under the Black-Scholes methodology and, ultimately, the expense that will be recognized over the life of the option. The accountingstandard for stock-based compensation requires that the Company recognize compensation expense for only the portion of options that are expected to vest.Therefore, the Company has estimated expected forfeitures of stock options for the grants valued. In developing a forfeiture rate estimate, the Company consideredits historical experience and actual forfeitures for the year. The Company will continue to evaluate its forfeiture rate as compared to the actual number of forfeituresin future periods to determine if adjustments to compensation expense may be required.F- 22Table of ContentsYIELD10 BIOSCIENCE, INC.(formerly known as Metabolix, Inc.)NOTES TO THE CONSOLIDATED FINANCIAL STATEMENTS(In thousands, except for share and per share amounts)Restricted Stock UnitsDuring 2015, the Company initiated use of Restricted Stock Units ("RSUs") as a broad-based form of long-term compensation incentive for its officers,directors and employees. On April 1, 2015, the Company awarded 203,967 RSUs under the 2014 Plan to members of senior management pursuant to electionspreviously made by the senior managers to convert a portion of their 2014 performance bonuses from cash to equity. These RSUs vested one year later on April 1,2016. During the year ended December 31, 2015, the Company also awarded a total of 906,806 additional long-term incentive RSUs to senior management andemployees. These RSUs vest in four equal annual installments beginning one year after the date of grant, subject to service conditions. On September 10, 2015, theCompany awarded 81,250 RSUs to its non-employee directors. These RSUs vested on May 28, 2016.Upon execution of the separation agreement with our former CEO on November 4, 2016, the Company accelerated the vesting of 151,250 previouslyoutstanding RSUs awarded to him in 2015. The Company recorded stock compensation expense for the fair value of these RSUs during its fiscal quarter endedDecember 31, 2016, as a result of the accelerated vesting. The accelerated vesting of the RSUs and existing stock options previously discussed was providedpursuant to the terms of the separation agreement in lieu of any cash severance and 2016 cash bonus payable under the CEO's previous employment agreement.The Company records stock compensation expense for RSUs on a straight line basis over their vesting period based on each RSU's award date marketvalue. The Company recognizes compensation expense for only the portion of awards that are expected to vest. Therefore, the Company has estimated expectedforfeitures of RSU's for the awards valued. In developing a forfeiture rate estimate, the Company considered its historical experience and actual forfeitures for theyear. The Company will continue to evaluate its forfeiture rate as compared to the actual number of forfeitures in future periods to determine if adjustments tocompensation expense may be required.The Company will pay minimum required income tax withholding associated with RSUs for its employees. As the RSUs vest, the Company will withholda number of shares with an aggregate fair market value equal to the minimum tax withholding amount (unless the employee makes other arrangements for paymentof the tax withholding) from the common stock issuable at the vest date. During the year ended December 31, 2016, the Company withheld vested shares with afair value of $296 to pay for minimum tax withholding associated with RSU vesting. No such amounts were paid during the year ended December 31, 2015.A summary of RSU activity for the year ended December 31, 2016 is as follows: Number of RSUsWeighted AverageRemaining ContractualLife (years)Outstanding at December 31, 20151,286,773 Awarded— Released(605,381) Forfeited(420,109) Outstanding at December 31, 2016261,2831.25 Vested and expected to vest as of December 31, 2016202,7101.21 Weighted average remaining recognition period (years)2.25 Weighted average grant date fair value of RSUs granted during the year ended December 31, 2016$— F- 23Table of ContentsYIELD10 BIOSCIENCE, INC.(formerly known as Metabolix, Inc.)NOTES TO THE CONSOLIDATED FINANCIAL STATEMENTS(In thousands, except for share and per share amounts)Expense Information for Non-employee Stock AwardsDuring the year ended December 31, 2016, the Company granted stock options to purchase 55,000 shares of common stock to non-employee members of theCompany's scientific advisory board. The compensation expense related to these options is to be recognized over a period of 2 years . The granted options vest 50%annually and such vesting is contingent upon future services provided by the advisors to the Company. Stock compensation expense of $9 related to these non-employee stock awards was recorded during the year ended December 31, 2016. No options were awarded and no stock compensation expense was recorded forthe year ended December 31, 2015, related to non-employee option grants. Options remaining unvested for non-employees are subject to remeasurement eachreporting period prior to their vesting in full. Since the fair market value of the options issued to non-employees is subject to change in the future, the compensationexpense recognized each year may not be indicative of future stock-based compensation charges.11. Income TaxesThe components of loss from continuing operations before provision for income taxes consist of the following: Year Ended December 31, 2016 2015 Domestic $(10,318) $(12,406) Foreign 48 21 Loss before taxes $(10,270) $(12,385) The reported amount of income tax expense for the years differs from the amount that would result from applying domestic federal statutory tax rates topretax losses primarily because of changes in valuation allowance. Significant components of the Company's net deferred tax assets are as follows: Year Ended December 31, 2016 2015 Deferred Tax Assets: Net operating loss carryforward $25,182 $9,904 Capitalization of research and development expense 2,634 15,070 Credit carryforwards 2,048 1,312 Depreciation 1,505 2,148 Stock compensation 2,414 4,902 Other temporary differences 1,202 1,186 Total deferred tax assets. 34,985 34,522 Valuation allowance (34,985) (34,522) Net deferred tax assets — — Deferred Tax Liabilities: Other temporary differences — — Net deferred taxes $— $— F- 24Table of ContentsYIELD10 BIOSCIENCE, INC.(formerly known as Metabolix, Inc.)NOTES TO THE CONSOLIDATED FINANCIAL STATEMENTS(In thousands, except for share and per share amounts)The items accounting for the difference between the income tax benefit computed at the federal statutory rate of 34% and the provision for income taxeswere as follows: Year Ended December 31, 2016 2015 Federal income tax at statutory federal rate 34.0 % 34.0 % State taxes 5.0 % 5.0 % Permanent differences (1.9)% (3.9)% Tax credits 7.4 % 6.9 % State rate change on deferred balances (0.6)% (0.1)% Impact of ownership change (6.1)% 3.3 % Stock compensation (22.9)% 0.0 % Other (0.5)% 0.6 % Change in valuation allowance (3.7)% (45.8)% Total 10.7 % 0.0 % The tax years 2013 through 2016 remain open to examination by major taxing jurisdictions to which the Company is subject, which are primarily in theU.S. The statute of limitations for net operating losses utilized in future years will remain open beginning in the year of utilization.The Company's policy is to record estimated interest and penalties related to uncertain tax positions as income tax expense. As of December 31, 2016 and2015 , the Company had no accrued interest or penalties recorded related to uncertain tax positions.At December 31, 2016 , the Company had net operating loss carryforwards (NOLs) for federal, state and international income tax purposes ofapproximately $63,285 , $58,732 and $2,404 , respectively. Included in the federal and state net operating loss carryforwards is $543 deduction related to theexercise of stock options. This amount represents an excess tax benefit which will be realized when it results in a reduction of cash taxes in accordance with ASC718. The Company's existing federal and state net operating loss carryforwards will begin to expire on various dates through 2036. The Company also hadavailable research and development credits for federal and state income tax purposes of approximately $1,195 and $673 , respectively. These federal and stateresearch and development credits will begin to expire in 2034 and 2029, respectively. As of December 31, 2016 , the Company also had available investment taxcredits for state income tax purposes of $14 , which also begin to expire in 2017. Management of the Company has evaluated the positive and negative evidencebearing upon the realizability of its deferred tax assets, which are comprised principally of net operating loss carryforwards and research and development credits.Under the applicable accounting standards, management has considered the Company's history of losses and concluded that it is more likely than not that theCompany will not recognize the benefits of federal and state deferred tax assets. Accordingly, a full valuation allowance has been established against the deferredtax assets.Utilization of the net operating loss and research and development credit carryforwards may be subject to a substantial annual limitation underSection 382 of the Internal Revenue Code of 1986 due to ownership change limitations that have occurred previously or that could occur in the future. Theseownership changes may limit the amount of net operating loss and research and development credit carryforwards that can be utilized annually to offset futuretaxable income and tax, respectively. The Company completed an evaluation of its ownership changes through December 31, 2015 and determined that anownership change occurred on August 22, 2014 in connection with the Company's issuance of Common and Series B Convertible Preferred stock. As aconsequence of this ownership change, the Company's NOLs, tax credit carryforwards and other tax deductions allocable to the tax periods preceding theownership change became subject to limitation under Section 382. The Company has reduced its associated deferred tax assets accordingly. The Company has notyet completed an evaluation of ownership changes through December 31, 2016. To the extent an ownership changeF- 25Table of ContentsYIELD10 BIOSCIENCE, INC.(formerly known as Metabolix, Inc.)NOTES TO THE CONSOLIDATED FINANCIAL STATEMENTS(In thousands, except for share and per share amounts)occurs in the future, the net operating loss, credit carryforwards and other deferred tax assets may be subject to further limitations.For the year ended December 31, 2016, the Company recognized tax expense of $1,097 as a result of net income recorded for discontinued operations.This tax expense is offset in consolidation by a tax benefit of $1,097 as a result of the Company's net loss from continuing operations.No additional provision has been made for U.S. income taxes related to the undistributed earnings of the wholly-owned subsidiaries of Yield10Bioscience, Inc. or for unrecognized deferred tax liabilities for temporary differences related to investments in subsidiaries as the amounts are not significant. Assuch, earnings are expected to be permanently reinvested, the investments are essentially permanent in duration, or the Company has concluded that no additionaltax liability will arise as a result of the distribution of such earnings. A liability could arise if amounts are distributed by such subsidiaries or if such subsidiaries areultimately disposed. It is not practical to estimate the additional income taxes related to permanently reinvested earnings or the basis differences related toinvestment in subsidiaries. Unremitted earnings at December 31, 2016 and December 31, 2015 approximated $346 and $311 , respectively.12. Employee BenefitsThe Company maintains a 401(k) savings plan in which substantially all of its regular U.S. employees are eligible to participate. Participants maycontribute up to 60% of their annual compensation to the plan, subject to eligibility requirements and annual IRS limitations. The Company's plan provides for amatching contribution in common stock of up to 4.5% of a participant's total compensation dependent upon the level of participant contributions made during theplan year. Pursuant to this plan, the Company issued 319,309 , and 131,113 shares of common stock during the years ended December 31, 2016 , and 2015 ,respectively, and recorded $281 , and $323 , respectively, of related expense. Company contributions are fully vested upon issuance.13.

Ifany term of this Agreement fails to conform with those laws and regulations, the relevant term is an invalid provision andshall be modified by the parties pursuant to Section l0.7.2.4. Option Right . Under the Intellectual Property Rights Agreement effective June 1, 2012, between UMass, Metabolix, Inc., TheRegents of the University of California (Berkeley), and Washington State University, Metabolix, Inc. has first option to negotiate for anexclusive license to UMass inventions developed under ARPA-E award grant no. DE-AR0000200 . The parties acknowledge that shouldadditional UMass inventions arise under ARPA-E grant no. DE AR0000200 which cannot be practiced without infringing the Patent Rights,it would be common practice to add such inventions to the existing license agreement rather than negotiate separate license agreement(s). Theparties also agree that it would be unusual for a licensee to pay multiple additive royalties if a Licensed Product is covered by more than onepatent in the same patent family. For purposes of clarity, the aforementioned acknowledgement and agreement in no way obligates UMass toenter into an agreement with Metabolix that would provide for the licensing of such inventions to Metabolix, especially under terms thatwould not represent a fair market value for the inventions.3.
