Company Overview

PART I

ITEM 1. BUSINESS

We engineer enzymes for pharmaceutical, biofuel and chemical production. Our proven technologies enable scale-up and implementation of biocatalytic
solutions to meet customer needs for rapid, cost-effective and sustainable process development, from research to manufacturing.

We have commercialized our technology and products in the pharmaceuticals market, which is our primary business focus. There are currently over 50
pharmaceutical firms using our technology, products and services in their manufacturing process development, including in the production of some of the
world's bestselling and fastest growing drugs.

We are a developing our CodeXyme® cellulase enzymes to convert non-food plant material, or cellulosic biomass, into affordable sugars, which can then be
converted into renewable fuels and chemicals. We are also developing our own manufacturing process for CodeXol® detergent alcohols, which are bio-based
chemicals. Detergent alcohols are used to manufacture surfactants, which are key, active cleaning ingredients in consumer products such as shampoos, liquid
soaps and laundry detergents. We are seeking collaboration partners to assist us with the development and commercialization of CodeXyme® cellulase
enzymes and CodeXol® detergent alcohols, and we are also exploring other strategic options with respect to these products and technologies.

We create our products by applying our CodeEvolver® directed evolution technology platform, which introduces genetic mutations into microorganisms,
giving rise to changes in the enzymes that they produce. Once we identify potentially beneficial mutations, we test combinations of these mutations until we
have created variant enzymes that exhibit marketable performance characteristics superior to competitive products. This process allows us to make
continuous, efficient improvements to the performance of our enzymes.

In this Annual Report, the “Company,” “we,” “us” and “our” refer to Codexis, Inc. and its subsidiaries on a consolidated basis.

Our Pharmaceutical Enzymes and Intermediates

We market and sell enzymes, development services and screening tools that enable novel manufacturing processes for active pharmaceutical ingredients, or
APIs, and their precursor pharmaceutical intermediates. We also market and sell pharmaceutical intermediates that are manufactured using our custom
enzymes. Our customers include several of the largest global pharmaceutical companies. Our pharmaceutical products and services have become the focus of
our business since the termination of our collaboration with Equilon Enterprises LLC dba Shell Oil Products US, or Shell, as described in more detail below.

Our pharmaceutical products and services enable novel manufacturing processes that can lower production costs and reduce capital intensity. These products
and services can provide numerous benefits to our customers, including:

•

•

•

•

•

•

•

•

reducing the use of raw materials and intermediate products;

CodeXyme® Cellulase Enzymes

Many of the fuels and chemicals that are in use today are derived from non-renewable petroleum resources. CodeXyme® cellulase enzymes allow these same
fuels and chemicals to be made from renewable resources, such as cellulosic biomass. Fuels and chemicals produced from these types of materials and wastes
are known as “second generation,” “next generation,” or “cellulosic” products. Today, cellulosic fuels and chemicals are not widely manufactured at
commercial scale because their unit production economics have not yet been shown to be competitive with incumbent petroleum-based fuels and chemicals.
We believe that CodeXyme® cellulase enzymes may help drive competitive production economics for cellulosic fuels and chemicals, thereby enabling their
integration into global commodity markets.

CodeXyme® cellulase enzymes function by transforming cellulosic biomass into sugars, a process known as saccharification. The resulting sugars from
saccharification can be converted into fuels and chemicals through fermentation. Our goal is to make CodeXyme® cellulase enzymes the leader in the
cellulase enzyme category.

As described in more detail below under “Collaborations and License Agreements-Shell,” our existing collaboration with Equilon Enterprises LLC dba Shell
Oil Products US, or Shell, for the commercialization of CodeXyme® cellulase enzymes in the fuels market terminated in August 2012. As a result of the
termination of the Shell collaboration, we initiated a series of cost reduction measures and refocused our business on the pharmaceuticals market. We
terminated approximately 173 employees worldwide, consisting of 150 research and development staff and 23 general and administrative staff. We also
closed our Singapore research and development facility.

We are seeking new collaboration partners to assist us with the development and commercialization of CodeXyme® cellulase enzymes. Moving forward with
partners should allow us to focus on our primary competitive strength, which we believe is our ability to optimize the performance of CodeXyme® cellulase
enzymes rapidly for varying feedstocks and process conditions. We are also exploring other strategic options for our CodeXyme® cellulase enzyme
technologies.

CodeXol® Detergent Alcohols

We are also developing microorganisms that produce chemicals from cellulosic sugars. These microorganisms function as mini fermentation factories that
convert sugars into specialty or commodity chemicals. Our first chemical development initiative is our bio-based CodeXol® detergent alcohols program.

Detergent alcohols are used to manufacture surfactants, an active ingredient in consumer products, such as shampoos, liquid soaps and laundry detergents.
The annual global market for detergent alcohols is approximately $4 billion, which represents approximately 2 million metric tons with an average selling
price, or ASP, of approximately $1,400 per ton today. Major consumer products companies such as Procter & Gamble, Unilever and Henkel purchase or
produce a majority of the surfactants derived from detergent alcohols.

Currently, detergent alcohols are manufactured using two alternative processes. The process of manufacturing detergent alcohols using vegetable oils, such as
palm, kernel and coconut oils, is known as the oleochemical production route. The process of manufacturing detergent alcohols using ethylene is known as
the petrochemical production route. We believe that our CodeXol® detergent alcohols process, by using cellulosic sugars, has the potential to offer attractive
production economics compared to incumbent oleochemical and petrochemical production routes.

We are developing our fully integrated cellulosic CodeXol® detergent alcohols manufacturing process, from feedstock to product, in collaboration with
Chemtex. We believe that our CodeXol® detergent alcohols process may be used with a wide variety of cellulosic biomass, including sugarcane bagasse,
wheat straw, corn stover and various energy crops such as Arundo donax. We believe that this process has the potential to decrease the manufacturing costs of
CodeXol® detergent alcohols below current incumbent production costs. We also believe that in comparison to using oleochemical and petrochemical
production routes, the raw materials of which raise concerns regarding deforestation, climate change and other environmental impacts, using CodeXol®
detergent alcohols in their manufacturing process would better enable major consumer products companies to achieve their sustainability and corporate social
responsibility goals. One example of such corporate social responsibility goal is the Sustainable Living Plan announced by Unilever, under which Unilever is
committed to sourcing 100% of its agricultural raw materials sustainably by 2020. We are seeking additional collaboration partners to assist us with the
development and commercialization of CodeXol® detergent alcohols. We are also exploring other strategic options for our CodeXol® detergent alcohols
technologies.

Our Strategy

Continue growing our pharmaceutical business. We intend to pursue new collaborations in the pharmaceutical industry to integrate our products and services
more deeply into drug development and manufacturing processes for clinical stage and commercially approved pharmaceutical products. As part of that
effort, we will continue to market our Codex® Biocatalyst Panels and our Codex® Biocatalyst Kits aggressively to pharmaceutical companies to demonstrate
the capabilities of our technology platform.

Seek partners to invest in our CodeXyme® cellulase enzyme and CodeXol® detergent alcohol programs, or identify and effect other strategic options with
respect to those programs. We are currently in the process of identifying potential partners for our CodeXyme® cellulase enzyme and CodeXol® detergent
alcohol programs so that we can leverage our partners' engineering, manufacturing or commercial expertise, their distribution infrastructure and their ability
to fund commercial scale production facilities. This capital-light partnership model would enable us to commercialize these projects without requiring
significant additional capital from us. We are also exploring other strategic options for these programs.

Explore commercial opportunities by leveraging our existing enzyme optimization technology. We intend to employ our existing enzyme optimization
technology to explore new business opportunities, including in the fine chemical market. The fine chemicals market is similar to our pharmaceutical
ingredients business and consists of several large market segments that we will explore for new business opportunities. Additionally, we intend to employ our
existing enzyme optimization technology to develop improved therapeutic enzymes for our pharmaceutical customers

Improve our CodeEvolver® directed evolution technology platform. We intend to continue to improve our CodeEvolver® directed evolution technology
platform, which may allow us to maintain a technology advantage over our customers and competitors. Improving our core technology capabilities should
allow us to reduce the cost and time to develop new products for our customers.

Our Pharmaceutical Products and Services

Our Opportunity in the Pharmaceutical Market

The pharmaceutical industry continues to represent a significant market opportunity for us, and has become our primary business focus since the termination
of the Shell collaboration. Pharmaceutical companies are now under significant competitive pressure both to reduce costs and to increase the speed to market
for their products. To meet these pressures, pharmaceutical companies seek manufacturing processes for their new and existing drugs that reduce overall
costs, simplify production and increase efficiency and product yield, while not affecting drug safety and efficacy. In addition, for products whose patents have
expired, the importance of cost reduction is even higher, as the pharmaceutical manufacturers that developed those patent-protected drugs, known as
innovators, compete with generics manufacturers.

The pharmaceutical product lifecycle begins with the discovery of new chemical entities and continues through preclinical and clinical development, product
launch and, ultimately, patent expiration and the transition from branded to generic products. As innovators develop, produce and then market products,
manufacturing priorities and processes evolve. Historically, innovators have focused on production cost reduction in the later stages of clinical development
and have been reluctant to make process changes after a product has been launched. However, as pressures to reduce costs have increased, innovators have
pursued cost reduction measures much earlier in the pharmaceutical product lifecycle and are increasingly looking for opportunities to improve their
operating margins, including making manufacturing process changes for marketed products after the products have been launched if these changes can result
in significant cost reductions. As a result, innovators are investing in new technologies to improve their manufacturing productivity and efficiency or
outsourcing the manufacture of their intermediates and active pharmaceutical ingredients, or APIs.

Our Solution for the Pharmaceutical Market

Our CodeEvolver® directed evolution technology platform enables us to deliver solutions to our customers in the pharmaceutical market by developing and
delivering optimized enzymes that perform chemical transformations at a lower cost and improve the efficiency and productivity of manufacturing processes.
We provide value throughout the pharmaceutical product lifecycle. Our pharmaceutical products and services allow us to provide benefits to our customers in
a number of ways, including:

•

•

reducing the use of raw materials and intermediate products;

reducing the number of processing steps;

6

Table of Contents

•

improving product yield;

•

•

•

•

•

•

•

using water as a primary solvent;

performing reactions at or near room temperature and pressure;

eliminating the need for certain costly manufacturing equipment;

reducing energy requirements;

reducing the need for late-stage purification steps;

eliminating multiple steps in the manufacturing process; and

eliminating hazardous inputs and harmful emission by-products.

Early in the product lifecycle, customers can use our products and services to achieve speed to market and to reduce manufacturing costs. If an innovator
incorporates our products or processes into an FDA-approved product, we expect the innovator to continue to use these products or processes over the patent
life of the approved drug.

After a product is launched, customers also use our products and services to reduce manufacturing costs. At this stage, changes in the manufacturing process
originally approved by the FDA may require additional review. Typically, pharmaceutical companies will only seek FDA approval for a manufacturing
change if there are substantial cost savings associated with the change. We believe that the cost savings associated with our products may lead our customers
to change their manufacturing processes for approved products and, if necessary, seek FDA approval of the new processes which incorporate our enzymes.
Moreover, we believe these cost savings are attractive to generics manufacturers, who compete primarily on price.

Products and Services

Codex® Biocatalyst Panels and Kits. We sell Codex® Biocatalyst Panels and Kits to customers who are engaged in both drug development and the marketing
of approved drugs to allow them to screen and identify possible enzymatic manufacturing processes for their drug candidates and their marketed products.
Codex® Biocatalyst Panels are tools that provide genetically diverse variants of our proprietary enzymes, which allow our customers to determine whether an
enzyme produces a desired activity that is applicable to a particular process. Codex® Biocatalyst Kits provide subsets of the Panel enzymes in individual vials
for the same purpose.

For compounds that are in development, Codex® Biocatalyst Panels and Kits:

•

•

allow innovators to screen and identify possible enzymatic manufacturing processes rapidly and inexpensively for many of their drug candidates
in-house, without the risks of disclosing the composition of their proprietary molecules before they have received patent protection; and

generate data that we can use to optimize enzymes rapidly for a particular reaction, if necessary, reducing the time required to generate a
manufacturing process capable of supporting clinical trials with inexpensively produced, pure drugs.

We believe that our Codex® Biocatalyst Panels and Kits have helped us build early and broad awareness of the power and utility of our technology platform,
and will increasingly lead to sales of our enzymes and enzyme optimization services, as well as intermediates and APIs made using our enzymes. Over 50
customers, including leading pharmaceutical companies such as Teva, Merck, Novartis and Pfizer, have used our panels and kits. If our customers incorporate
an enzymatic manufacturing process early in a product's lifecycle, they can reduce their manufacturing costs throughout that lifecycle, while we, in turn,
could realize a long term revenue stream resulting from the use of our enzymes during that time. In addition, Codex® Biocatalyst Panels and Kits are
increasingly used by our customers to evaluate the feasibility of changing the manufacturing process for their marketed products to an enzyme-enabled
process.  

Enzyme screening services. If a customer prefers, rather than subscribing to our Codex® Biocatalyst Panels or Kits to use for their own screening, they can
send us their materials to test against our existing libraries of enzymes. If we detect desired activity in a specific enzyme, we can supply the customer with
this enzyme or perform optimization services to improve the performance of the enzyme.

7

Table of Contents

Our screening services:

•

•

allow innovators to screen and identify possible enzymatic manufacturing processes rapidly and inexpensively through access to our extensive
enzyme libraries; and

generate data that we can use to optimize enzymes rapidly for a particular reaction, if necessary, reducing the time required to generate a
manufacturing process capable of supporting the customers' particular needs, ranging from small quantities for clinical trials to full commercial
production, in all cases providing inexpensively produced, pure drugs.

We have provided screening services to numerous innovator and generic pharmaceutical manufacturers.

Enzyme optimization services. We work with our customers throughout the pharmaceutical product lifecycle to customize enzymes, resulting in optimized
enzymes that have been evolved specifically to perform a desired process according to a highly selective set of specifications.

Our enzyme optimization services:

•

•

allow innovators to improve the manufacturing process as their drug candidates progress through preclinical and clinical development, in some
cases deferring or reducing the need for significant manufacturing investment until the likelihood of commercial success is more certain; and

enable manufacturing processes that are highly efficient, inexpensive, require relatively little energy, reduce the need for hazardous reagents and
reduce waste. For example, our activities with Pfizer have included developing an optimized enzymatic manufacturing process for a key
intermediate that eliminates three chemical steps from the conventional chemical manufacturing process.

Enzymes. We supply varying quantities of our enzymes to pharmaceutical companies, from small to moderate quantities while they are optimizing their
production processes, to larger quantities during later-stage clinical development and commercial scale drug production.

Our enzymes:

•

•

•

•

•

•

enable innovators to manufacture products more efficiently during preclinical and clinical development using optimized enzymatic processes,
with relatively low investment;

eliminate the need for innovators to invest in the development of complex chemical synthesis routes during the development stage;

allow innovators to achieve higher product purity during the development stage prior to investing in expensive late-stage clinical trials;

reduce the risk of adverse effects arising from product impurities;

allow the removal of entire steps from synthetic chemical production routes during commercial scale production, reducing raw material costs,
energy requirements and the need for capital expenditures; and

decrease the manufacturing costs for our customers.

For instance, as a part of our ongoing collaboration with Merck, we have developed an enzyme for use in a new manufacturing process for sitagliptin, the API
in Merck's pharmaceutical product Januvia®. Januvia® is Merck's first-in-class medication for the treatment of Type II diabetes. We have also entered into
agreements with several leading contract manufacturing organizations, or CMOs, including Royal DSM N.V., or DSM, Dishman Pharmaceuticals and
Chemicals, Ltd., and AMPAC, under which these CMOs can use our enzymes in their manufacturing processes.

Intermediates and APIs. We can supply our customers with intermediates and APIs made using our enzymes throughout the drug lifecycle.

Our supply of intermediates has the following uses and benefits:

•

•

lowers capital investment for innovators through outsourcing of manufacturing; and

provides a source of less expensive, more pure products to innovator and generics manufacturers.

8

Table of Contents

We developed a key intermediate for boceprevir, which is Merck's hepatitis C drug. We have also developed enzymes for use in the manufacture of certain
generic intermediates and APIs by various companies, including Arch Pharmalabs Limited, or Arch, and Teva Pharmaceutical Industries Ltd., or Teva. In
addition, we market several intermediates and APIs for the generic equivalents of branded pharmaceutical products for sale in markets where innovators have
not sought patent protection for their products and intend to sell these same intermediates and APIs for use in markets where innovators have sought patent
protection when the patent protection for each product expires.

For the years ended December 31, 2010, 2011 and 2012, revenues for our statin-family of products contributed approximately 15%, 24% and 24%,
respectively, of our total revenues and our sales of products used in hepatitis C therapies were approximately 6%, 9% and 10%, respectively, of our total
revenues for those periods.

Pharmaceutical Business Model

We typically enter into research collaborations with our pharmaceutical customers. These agreements often contain service and intellectual property
provisions under which we research and develop optimized enzymes for innovator pharmaceutical companies in connection with their drug development
efforts. In these collaborations, we typically receive revenues in the form of one or more of the following: up-front payments, milestone payments, payments
based upon the number of full-time employee equivalents, or FTEs, engaged in related research and development activities and licensing fees and royalties.

Our pharmaceutical products include enzymes, pharmaceutical intermediates, active pharmaceutical ingredients, or APIs, and Codex® Biocatalyst Panels and
Kits. We sell our products primarily to pharmaceutical manufacturers through our direct sales and business development force in the United States and
Europe.

Our CodeXyme® Cellulase Enzyme Program

Industry Overview

The global economy is heavily dependent on petroleum. Many of the fuels and chemicals that are used throughout the world are derived from non-renewable
petroleum and concerns about the long-term supply of petroleum and its price volatility have increased the desire to find renewable alternatives to this limited
commodity. Many fuels and chemicals manufactures are looking for alternatives to non-renewable petroleum, including cellulosic biomass, as a feedstock for
their products.

Fuels and chemicals derived from corn starch, sugar cane or plant oils are called “first generation” products and those derived from cellulosic biomass (such
as corn stover, wheat straw and sugar cane bagasse) are known as “second generation,” “next generation” or “cellulosic” products. In order to produce a
cellulosic product using fermentation, a manufacturer must first pretreat the cellulosic biomass and then introduce cellulase enzymes into the manufacturing
process. Together, these steps work to break down the cellulose and hemicellulose found in the cell walls of the cellulosic biomass into sugars. This process is
commonly referred to as saccharification. These sugars can then be converted into biofuels and chemicals through fermentation. Producing second generation
fuels and chemicals is a more complicated process than producing first generation products. As a result, most biofuel and bio-based chemical manufacturers
have chosen to develop and commercialize first generation products.

Sources of cellulosic biomass vary greatly by plant species and geographic region. One of the challenges for manufacturing cellulosic products is the need for
technology that can convert the vast array of cellulosic biomass found throughout the world into fermentable sugars. Solving this challenge requires cellulosic
biofuels and chemicals manufacturers to develop innovative, robust cellulase enzymes that have greater product yield, are more cost-effective, and react
quickly and continually under industrial conditions. We do not believe that anyone has successfully accomplished this goal cost-effectively and at commercial
scale.

CodeXyme® Cellulase Enzymes

We believe that CodeXyme® cellulase enzymes will enable the production of cellulosic fuels and bio-based chemicals cost-effectively and at commercial scale
and that they may help drive competitive production economics for cellulosic fuels and chemicals, thereby enabling their integration into global commodity
markets. CodeXyme® cellulase enzymes have the potential to convert a wide variety of cellulosic biomass into fermentable sugars, an important feature
because the cellulosic biomass that we expect will be used to produce cellulosic products is highly variable from region to region and can change over time.
For example, CodeXyme® cellulase enzymes convert both sugar cane bagasse and wheat straw to fermentable sugars. In addition, we licensed a commercial-
scale enzyme production system from Dyadic International, Inc., or Dyadic, in 2008 that we expect will enable the cost-effective production of CodeXyme®
cellulase enzymes. We believe that the combination of our high-performing CodeXyme® cellulase enzymes and the ability to produce these cellulase enzymes
cost-effectively at commercial

scale, will enable us to develop a scalable, global platform that will provide us and our customers a competitive advantage in the cellulosic products market.

We collaborated with Shell to develop CodeXyme® cellulase enzymes from November 2006 through August 2012. When this collaboration ended in August
2012, we no longer received funding from Shell for development of CodeXyme® cellulase enzymes. As a result, we reduced the scope of our development
activities for this project, refocused our business on the pharmaceuticals market and initiated a series of cost reduction measures, including employee
terminations and the closure of our Singapore research and development facility. We are now seeking new collaboration partners to assist us with the
development and commercialization of CodeXyme® cellulase enzymes. Moving forward with partners should allow us to focus on our primary competitive
strength, which we believe is our ability to optimize the performance of CodeXyme® cellulase enzymes rapidly for varying feedstocks and process conditions.
We are also exploring other strategic options for our CodeXyme® cellulase enzyme program.

Our CodeXol® Detergent Alcohols Program

Industry Overview

Detergent alcohols are used to manufacture surfactants, a key, active cleaning ingredient in consumer products such as shampoos, liquid soaps and laundry
detergents. Sodium lauryl sulfate and ammonium lauryl sulfate are two such common surfactants. The annual global market for detergent alcohols is
approximately $4 billion, which represents approximately 2 million metric tons with an ASP of approximately $1,400 per ton. Major consumer products
companies, such as Procter & Gamble, Unilever and Henkel, purchase or produce a majority of the surfactants made from detergent alcohols.

Currently, detergent alcohols are manufactured using two alternative processes. The process of manufacturing detergent alcohols using vegetable oils, such as
palm, kernel and coconut oils, is known as the oleochemical production route. The process of manufacturing detergent alcohols using ethylene is known as
the petrochemical production route. The production economics of traditional detergent alcohol manufacturing routes are primarily based on the market prices
of their respective feedstocks. Both ethylene and palm kernel oil prices have risen considerably in recent years, leading to a significant rise in the price of
detergent alcohols. Between 2002 and 2008, global detergent alcohol prices rose from $2,000 per ton to over $3,000 per ton, and in early 2011, prices higher
than approximately $4,000 per ton were observed for the first time in recent history before returning back to the $1,400 per ton range.

In addition to price volatility, consumer products companies face sustainability and corporate social responsibility issues with traditional detergent alcohols.
The oleochemical route, which as of 2009 accounted for over two-thirds of global detergent alcohol production, has led to concerns of deforestation due to the
rapid expansion of palm oil plantations to meet growing demand. The petrochemical route uses petroleum-based ethylene manufacturing processes that are
also considered unsustainable. Many major consumer products companies today have adopted corporate social responsibility platforms in which they have
pledged to their customers and stockholders that they will use sustainable, socially responsible materials in their commercial products. For example:

•

•

Unilever's Sustainable Living Plan sets specific goals including halving the environmental footprint of the company's products and sourcing 100%
of the company's agricultural raw materials sustainably.

Procter & Gamble's Environmental Sustainability vision includes using 100% renewable or recycled materials for all products and packaging, and
designing products that appeal to customers while maximizing conservation of resources.

CodeXol® Detergent Alcohols

CodeXol® detergent alcohols can act as a drop-in substitute for over 70% of the estimated $4 billion detergent alcohol market. We expect that CodeXol®
detergent alcohols will offer advantages in feedstock price-volatility and sustainability when compared to traditional detergent alcohols.

We are developing our CodeXol® detergent alcohols manufacturing process, from feedstock to end product, in collaboration with Chemtex. Chemtex has
licensed to us, on an exclusive basis in the field of detergent alcohols, its PROESA pretreatment technology, which we are integrating with CodeXyme®
cellulase enzymes to create fermentable sugars. Our proprietary microorganism will then convert these sugars into CodeXol® detergent alcohols. We have
agreed to use the PROESA pretreatment technology exclusively to produce CodeXol® detergent alcohols. Similarly, Chemtex has agreed to work exclusively
with us in the production of cellulosic detergent alcohols. We expect that Chemtex will pilot this manufacturing process using CodeXyme® cellulase enzymes
and their PROESA pretreatment technology in 2013. Chemtex will provide

10

 
Table of Contents

engineering services for the design and construction of our commercial facilities for the production of CodeXol® detergent alcohols and we will market
products resulting from the collaboration.

CodeXol® detergent alcohols are manufactured using a process which is amenable to various types of cellulosic biomass, including sugarcane bagasse, wheat
straw, corn stover and various energy crops such as Arundo donax. We believe that this process has the potential to lower CodeXol® detergent alcohols'
manufacturing costs and make them less volatile than current incumbent manufacturing costs. Additionally, CodeXol® detergent alcohols are better aligned
with the sustainability and corporate social responsibility goals of major consumer products companies, like Unilever and Procter & Gamble, since it is
sourced from sustainable and renewable cellulosic biomass. We are seeking additional collaboration partners to assist us with the development and
commercialization of CodeXol® detergent alcohols. We are also exploring other strategic options for our CodeXol® detergent alcohols technology.

Collaborations and License Agreements

We believe that collaborations allow us to develop our products while operating our business with maximum capital efficiency. For example, by collaborating
with Arch, we are able to leverage both our CodeEvolver® directed evolution technology platform and Arch's strengths in production and distribution. This
allows us to focus our capital on key areas such as research and development.

Arch

We are collaborating with Arch of Mumbai, India in the supply of enzymes used in the manufacture and sale of certain specified APIs, and intermediates used
in the manufacture of APIs, such as the API in atorvastatin. Arch has extensive expertise in chemical process development and scale-up, and is a leading
producer of intermediates and generic APIs in India.

On November 1, 2012, we entered into an Enzyme Supply Agreement with Arch, or the New Arch Enzyme Supply Agreement, in which Arch agreed to
exclusively purchase enzymes from us for use in the manufacture of certain of Arch's products and we agreed to exclusively supply, with limited exceptions,
certain of our proprietary enzymes to Arch at an agreed upon price for use in such manufacture. The exclusivity may expire in certain circumstances,
including if Arch fails to purchase a specified minimum quantity of enzymes from us. Under the terms of the New Arch Enzyme Supply Agreement, Arch has
an obligation to use commercially reasonably efforts to market the products covered under the agreement to its customers. We have agreed not to buy or
source any of the covered products from anyone other than Arch and have agreed not to sell any covered products to any of Arch's customers. The New Arch
Enzyme Supply Agreement terminates on February 16, 2020, unless extended by mutual agreement of the parties or unless terminated at an earlier date in
accordance with the termination provisions contained in the agreement.

The New Arch Enzyme Supply Agreement replaced four of our prior agreements with Arch: the Enzyme and Product Supply Agreement, effective as of
February 16, 2010, as amended, the Memorandum of Understanding for Transfer Pricing and Royalty Calculation, effective as of February 16, 2010, as
amended, the Product Supply Agreement, effective as of February 16, 2010, as amended and the Memorandum of Understanding for Transfer Pricing,
effective as of February 16, 2010, as amended. These four terminated agreements are referred to as the Prior Arch Supply Agreements. The Prior Arch Supply
Agreements provided that the Company would supply Arch with enzymes at an agreed upon price, and Arch would in turn manufacture certain APIs, or
intermediates used in the manufacture of APIs, using those enzymes and would supply such APIs or intermediates to the Company at a formula-based or
agreed upon price. The Company had the exclusive right to sell such APIs or intermediates to innovator pharmaceutical companies worldwide, generic
pharmaceutical companies in the United States, Canada, Europe and Israel, and certain pharmaceutical companies in India. Arch had the exclusive right to
manufacture, market and sell such APIs or intermediates to generic pharmaceutical companies in countries other than the United States, Canada, Europe and
Israel, and certain other pharmaceutical companies in India. Under this collaboration, Arch owed a license royalty to us based on the volume of product they
sold to us or the customers to which it sold product directly. Royalties earned from Arch under this arrangement were $752,000 and $127,000 for the twelve
months ended December 31, 2011 and 2012, respectively. With the termination of the Prior Arch Supply Agreements, Arch will no longer produce APIs and
intermediates for us and will no longer pay us royalties on the sale of APIs and intermediates to customers, and we will no longer have exclusive rights to
market such APIs and intermediates in certain markets.

Dyadic

We have acquired access to a fungal expression system that is capable of producing enzymes at commercial scale through a license agreement with Dyadic
and its affiliate in November 2008. Under the license agreement with Dyadic, we obtained a non-exclusive license relating to Dyadic's proprietary fungal
expression technology for the production of enzymes. We can use these enzymes to make products in the fields of biofuels, certain pharmaceuticals,
chemicals, air treatment, water treatment and

11

Table of Contents

the conversion of cellulosic biomass into fermentable sugars for use in non-fuel products. We also obtained access to specified materials of Dyadic relating to
this technology. Our license is sublicenseable to Shell in the field of biofuels, and sublicenseable to third parties in the non-biofuels fields of certain
pharmaceuticals, chemicals, air treatment, water treatment and the conversion of cellulosic biomass into fermentable sugars for non-fuel products. Each party
agreed that neither it nor its affiliates or sublicensees will assert any claim of infringement of any patent covering improvements to the Dyadic materials that
were made by that party or its affiliates or sublicensees against the other party, or its affiliates, sublicensees, successors, distributors, or customers. We agreed
to pay Dyadic certain license issuance fees, milestone payments, and fees based on volume of enzyme products sold or manufactured using this Dyadic
technology. We have the right to terminate the license agreement at will upon notice after payment of the license issuance fees. Either party has the right to
terminate the license agreement for a material breach of the other party that is uncured within a period of time after notice. Dyadic has the right to terminate
our licenses under the license agreement if we challenge the validity of any of the patents licensed under the license agreement. Our licenses, and access to
Dyadic's materials, under the license agreement will terminate as a result of any termination of the license agreement other than due to Dyadic's material
breach.

Shell

From November 2006 to August 2012, we collaborated with Shell to develop commercially viable fuels from cellulosic biomass. In this collaboration, we
agreed to use our proprietary technology platform to discover and develop enzymes and microorganisms for use in converting cellulosic biomass into biofuels
and related products. Shell had an obligation to fund us at specified rates for each full-time employee equivalent, or FTE, which as of 2012 were equal to
$460,000 on an annual basis for each FTE in the United States and $399,000 on an annual basis for each FTE in Hungary. As of August 31, 2012, the number
of FTEs assigned by us to perform our obligations under the Research Agreement was 116. For the year ended December 31, 2012, Shell accounted for 51%
of our total revenues.

In September 2012, we entered into a license agreement, or the New Shell Agreement, with Shell. The New Shell Agreement terminated our collaboration
with Shell effective August 31, 2012. Pursuant to the terms of the New Shell Agreement, Shell paid us $7.5 million as full, complete and final satisfaction of
amounts payable by Shell with respect to FTEs and any milestones achieved or achievable by us our existing Amended and Restated Collaboration
Agreement, effective November 1, 2006, as amended, or the Shell Research Agreement. We have no further obligations to Shell under the Shell Research
Agreement to provide any FTEs to perform work under or after the collaboration and Shell correspondingly has no future obligations to us under the Shell
Research Agreement to provide funding for FTEs to perform work under or after the collaboration. We remain eligible to receive a one-time $3 million
milestone payment under the Shell Research Agreement upon the first sale by Shell of a product in the field of converting cellulosic biomass into fermentable
sugars in Brazil, or in the fields of converting fermentable sugars derived from biomass into liquid fuel or liquid fuel additives or into lubricants.

The New Shell Agreement also amended our existing Amended and Restated License Agreement, effective November 1, 2006, as amended, with Shell, or the
Shell License Agreement.

Under the New Shell Agreement, Shell granted us a royalty-bearing, non-exclusive rights and licenses to develop, manufacture, use and sell biocatalysts and
microbes in the field of converting cellulosic biomass into fermentable sugars on a worldwide basis, except for Brazil, where such sugars are converted into
liquid fuels, fuel additives or lubricants. This field is referred to as the Field of Use. Raízen Energia Participações S.A., or Raízen, holds the exclusive rights
to use our biocatalysts and microbes for converting cellulosic biomass into fermentable sugars in Brazil, where such sugars are converted into ethanol.
Following the date on which we, our affiliates or our customers produce sugars using biocatalysts in the Field of Use sufficient to produce 30,000,000 gallons
of liquid fuel, we will be required to pay Shell a royalty on our sales to third parties of biocatalysts and microbes in the Field of Use, equal to a low single-
digit percentage of net sales and we will also be required to pay Shell a royalty on the use by us or our affiliates of biocatalysts in the Field of Use, equal to a
low single-digit percentage of our applicable net sales of such biocatalysts or microbes or such amounts as are otherwise agreed by us and Shell. Shell is also
entitled to discounted pricing under the New Shell Agreement for biocatalysts purchased from us by Shell for use in the Field of Use, but we are under no
obligation to sell such biocatalysts to Shell.

Shell has also agreed not to sell any biocatalysts arising out of its collaboration with us to any third parties in the Field of Use, provided that such biocatalysts
constitute improvements to any and all biocatalysts that are derived from technology developed under our separate collaboration with Shell, Shell Chemicals
Canada Limited and Iogen Energy Corporation, or Iogen, and such improvements are made outside of that separate collaboration.

Under the New Shell Agreement, we also granted Shell a non-exclusive, royalty-free license to manufacture, use and import, solely for the use of Shell and its
affiliates, (i) enzymes developed by us during the ten year period following August 31, 2012 outside of the Shell Research Agreement for use in the Field of
Use and (ii) improvements to any microbe developed by us

12

Table of Contents

during the ten year period following August 31, 2012 outside of the Shell Research Agreement that is derivative of an identified microbe for use in the Field
of Use. Shell remains subject to existing royalty obligations to us for future sales of products covered by the intellectual property and technology that remain
exclusively licensed to Shell under the Shell License Agreement, on the terms and subject to the conditions contained in the Shell License Agreement.

The New Shell Agreement has a term that commences August 31, 2012 and continues until the later of August 31, 2032 or the date of the last to expire of
patent rights included in the Shell and Codexis collaboration that claim a biocatalyst or a microbe for use in the Field of Use.

We remain party to a separate Collaborative Research and License Agreement, effective as of July 10, 2009, with Shell and Iogen under which we agreed to
collaborate with Iogen and Shell to develop technology relating to the conversion of cellulosic biomass to ethanol. The research term of the collaboration with
Shell and Iogen ended in June 2012, while the collaboration term remains in effect; however, there is no collaborative activity continuing among the parties.

Technology

We engineer custom enzymes and microorganisms, which we sometimes refer to as biocatalysts. In simple terms, our enzymes and microorganisms initiate or
accelerate chemical reactions. We use our CodeEvolver® directed evolution technology platform, which includes enzyme engineering, metabolic pathway
engineering and fermentation microbe improvement, to develop novel enzymes and microorganisms that enable industrial biocatalytic reactions and
fermentations. Our technology platform has enabled commercially viable products and processes for the manufacture of pharmaceutical intermediates, and we
apply our technology platform to develop CodeXyme® cellulase enzymes and CodeXol® detergent alcohols.

Our approach to developing commercially viable biocatalytic processes begins by conceptually designing the most cost-effective and practical manufacturing
process for a targeted product. We then develop optimized biocatalysts to enable that process design, using our directed evolution technology, including
screening and validating biocatalysts under relevant conditions. Typical design criteria include stability in the desired reaction conditions, biocatalyst activity
and productivity (yield), ease of product isolation, product purity and cost. Alternative approaches to biocatalytic process development typically involve
designing and engineering the biocatalytic processes around shortcomings of available biocatalysts, including, for example, biocatalyst immobilization (for
stability and/or reuse), special equipment and costly product isolation and purification methods. We circumvent the need for these types of costly process
design features by optimizing the biocatalyst for fitness in the desired process environment. As a result, we enable and develop cost-efficient processes that
typically are relatively simple to run in conventional manufacturing equipment. This also allows for the efficient technical transfer of our process to our
manufacturing partners.

The successful embodiment of our CodeEvolver® directed evolution technology platform in commercial manufacturing processes requires well-integrated
expertise in a number of technical disciplines. In addition to those directly involved in practicing our directed evolution technologies, such as molecular
biology, enzymology, microbiology, cellular engineering, metabolic engineering, bioinformatics, biochemistry, and high throughput analytical chemistry, our
process development projects also involve integrated expertise in organic chemistry, chemical process development, chemical engineering, fermentation
process development, and fermentation engineering. Our integrated, multi-disciplinary approach to biocatalyst and process development is a critical success
factor for our company.

Enzyme Optimization Overview

The enzyme optimization process starts by identifying genes that code for enzymes known to have the general type of catalytic reactivity for a desired
chemical reaction. Typically, we identify gene sequences in published databases and then synthesize candidate genes having those sequences. Using a variety
of biotechnology tools, we diversify these genes by introducing mutations, giving rise to changes in the enzymes for which they encode. The methods for
diversifying these genes, and types of diversity being tested, often vary over the course of an enzyme optimization program. For finding initial diversity,
methods typically include random mutagenesis and site-directed (included structure-guided) mutagenesis. We also test mutational variations that distinguish
related enzymes among different organisms. Once we have identified potentially beneficial mutations, we test combinations of these mutations in libraries
made using our proprietary gene recombination methodologies, gene shuffling and multiplexed gene SOEing, or Splicing by Overlap Extension.  

With our proprietary gene shuffling methodology, we generate libraries of genes that have random combinations of the mutations we are testing. The pool of
genes is used to transform host cells, which entails introducing the various genes, one by one, into host cells. These cells are then segregated and grown into
colonies. Cells from individual colonies are cultured in high throughput to produce the enzyme encoded by the shuffled gene in those cells. The enzymes are
then screened in high throughput using test conditions relevant to the desired process. The screening results identify individual shuffled genes that

13

Table of Contents

produce improved enzymes having combinations of beneficial mutations and weed out enzymes having detrimental ones. Using different test conditions
and/or different analytical methods, we can identify variant enzymes that exhibit various improved performance characteristics, such as stability, activity and
selectivity, under conditions relevant to the desired chemical process.

In the next step in our optimization process, we use our proprietary software tool, ProSAR™, to analyze protein sequence-activity relationships. ProSAR™
aids in identifying specific gene and enzyme mutations that are beneficial, neutral or detrimental with respect to the desired performance characteristics.
Earlier directed evolution methods did not separately evaluate individual mutations in libraries of variants which carry multiple mutations, where beneficial
and detrimental performance characteristics may be mixed in an individual gene or enzyme. Capitalizing on the advent of inexpensive gene sequencing, we
are able to determine which particular mutations are present in the genes and proteins we have screened. Our ProSAR™ bioinformatics software relates the
screening results to the mutations and ranks the individual mutations with regard to their degree of benefit or detriment, relative to whichever process
parameter(s) the screening tested. Using that information, we can bias the pool of mutational diversity in the next iteration to further the accumulation of
beneficial diversity and cancel out detrimental diversity in the individual genes in the resulting shuffled library. The ProSAR™ results also help us develop
ideas about new diversity to test. ProSAR™, combined with efficient gene synthesis and high quality library generation methods, has led to a significant
increase in the efficiency and speed of enzyme improvement and optimization.

In another step of our optimization process, we take the best variants we have identified and prepare enough of each to test in the desired chemical process at
laboratory scale, for in-process confirmation. This optimization routine is done iteratively, typically adding new diversity to the pool in each iteration. The
gene that codes for the best performing enzyme in one iteration is used as the starting gene for the next iteration of shuffling and screening. As the enzymes
improve over these iterations, the screening conditions are made increasingly more stringent. In this way, enzymes are rapidly optimized until all in-process
performance requirements have been achieved and the economic objectives for the desired process have been met.

Multiplexed gene SOEing is our proprietary methodology for rapidly generating gene variants. Using multiplexed gene SOEing, we rapidly generate
collections of individual gene variants that have predetermined, as opposed to random, combinations of mutations we are testing. It is based on a
biotechnology technique, which we refer to as SOEing, generally used to make a hybrid, or spliced, gene from fragments of two genes and/or to introduce a
specific mutation into a splice between fragments of one gene. We have automated the process to make robotically, in parallel, one hundred to several
hundred variants, each with a predetermined combination of the mutations we are testing. The variants are introduced into host cells, and the encoded enzyme
is produced and screened in high throughput, as described above.

Using multiplexed gene SOEing, we can test many mutations and combinations thereof in parallel, and because the mutation incorporation is controlled and
predetermined before screening, as opposed to random incorporation and selection after screening, the resulting data set can be more optimal for ProSAR™
analysis.

We believe using multiplexed gene SOEing to survey many mutations quickly, followed by ProSAR™-driven shuffling of beneficial mutations, is a
particularly effective approach, providing rapid gains in enzyme performance.

Codex® Biocatalyst Panels and Kits

Codex® Biocatalyst Panels were initially developed to speed our own internal process for identifying enzymes with desired characteristics for further
optimization. Each Codex® Biocatalyst Panel is comprised of variants of one or more enzymes that catalyze one type of a generally useful chemical reaction.
We assemble, on one or more multi-well sample plates, variants of a parent enzyme that we pre-optimize for stability in industrial chemical processes and for
ready manufacturability. The variants are diversified to react to a variety of chemical structures that are susceptible to that type of chemical reaction.

Either we or our innovator pharmaceutical customers use the Codex® Biocatalyst Panels to screen a new chemical structure against the assembled variants to
identify variants that react with the new chemical structure rapidly. For some new structures, a variant on the panel could enable production of the desired
product. We can also analyze the data from the panel screen using ProSAR™ to identify the mutations that are beneficial for the reaction of the new structure
and further optimize the enzyme as needed using the enzyme optimization techniques described above. In cases where a customer wishes to screen a
proprietary new chemical structure itself, we can produce a custom panel of new variants on a sample plate produced by multiplexed gene SOEing.

In 2010, we launched Codex® Screening Kits as an alternative format to provide our enzymes to pharmaceutical development laboratories that are not
equipped to use multi-well sample plates. The enzymes are instead individually provided in vials for the researchers to sample. As of December 31, 2012,
Codex® Screening Kits were in use or evaluation in manufacturing process development at over 50 pharmaceutical companies worldwide.

Microbe Optimization using Gene Optimization

For fermentation microbes, we enhance metabolic pathways by using gene optimization to improve the production and/or productivity of one or more
enzymes in a series of in vivo reactions that make a desired product. We optimize the gene/enzyme as described above using either in vitro or in vivo
screening. For fermentation applications, the microbes containing the improved gene(s) are directly evaluated in laboratory scale fermenters.

The metabolic pathway may naturally exist in the microbe, but productivity and/or selectivity improvements are needed to produce more of the desired
natural product and/or less of an undesired by-product economically. We can also introduce a new metabolic pathway to produce a desired product using our
gene shuffling technology in combination with synthetic biology, a type of metabolic engineering in which new genes are introduced into a microbe.

Our gene/enzyme optimization methodologies can be used to optimize fermentation microbes, including optimization of:

•

•

•

native and introduced (non-native) cellulase genes for increased productivity in our cellulase production microbes;

an introduced (non-native) pathway in yeast for the conversion of xylose, a cellulose-derived sugar, to ethanol; and

an introduced (non-native) pathway in a microbe for the production of CodeXol® detergent alcohols.

Microbe Optimization using Whole Genome Shuffling

In addition to our gene optimization technology for enzymes, we have another complimentary technology in our platform for the optimization of fermentation
microbes called Whole Genome Shuffling. Whole Genome Shuffling allows us to improve the performance of a fermentation microbe by shuffling
unidentified mutations in unidentified genes across the genome. We start with a diversity of mutational variants of a fermentation organism, generated by
conventional means such as random mutagenesis. Our Whole Genome Shuffling involves introducing the entire genome of two or more such cells into a
single cell, in which the genetic machinery of the combined cell recombines, or shuffles, the genomes. In one method, this is accomplished by protoplast
fusion, in which the cell walls are removed to leave the cells' contents contained only by their cell membranes. The cell membranes of these protoplasts in the
diverse population are induced to fuse together into fusants containing the genome of two or more of the parent cells. From these fusants, we regenerate
normal cells, each with one copy of a hybridized genome. Microbial colonies are then grown and screened for their performance in the fermentative
production of the desired product. This process can be repeated, including with the introduction of new mutations, until the desired performance in the
fermentation process is achieved. One of our collaborators is operating a fermentation process for a generic pharmaceutical product using microbes we
developed by Whole Genome Shuffling.

We are using our Whole Genome Shuffling technology in our CodeXyme® cellulase enzyme program and our CodeXol® detergent alcohols program to
optimize fermentation microbes, including optimization of:

•

•

enzyme production hosts for increased production of cellulase enzymes; and

our detergent alcohol producing strain for increased productivity.

Metabolic Engineering and Synthetic Biology

In addition to our proprietary enzyme and microbe optimization technologies, we have built expert capabilities in a suite of new metabolic engineering
technologies for the development and optimization of fermentation microbes. These technologies are generally applicable to our pathway and strain
engineering programs. Genomics, transcriptomics, proteomics and metabolomics all provide more in-depth analyses of the metabolic functioning of
fermentation microbes, and differences between variants, to guide further improvements. In many cases, these analyses help to identify enzymes that need to
be modified (removed, increased, stabilized or otherwise modified) in order to increase the overall productivity and performance of the strain.

Synthetic biology involves the design, synthesis and introduction of new genetic programming to organisms for new biological functions. This field has
rapidly developed in recent years as DNA synthesis and sequencing costs have rapidly dropped. Using synthetic biology, we are taking advantage of the
publicly available gene and genome sequence information in our gene and metabolic pathway optimization projects. This information is being leveraged by
our ProSAR™ software and multiplexed gene SOEing methodologies.

Intellectual Property

Our success depends in large part on our ability to protect our proprietary products and technology under patent, copyright, trademark and trade secret laws.
We also rely heavily on confidential disclosure agreements for further protection of our proprietary products and technologies. Protection of our technologies
is important for us to offer our customers and partners proprietary services and products that are not available from our competitors, and to exclude our
competitors from practicing technology that we have developed or exclusively licensed from other parties. For example, our ability to supply innovator
pharmaceutical manufacturers depends on our ability to supply proprietary enzymes or methods for making pharmaceutical intermediates or APIs that are not
available from our competitors. Likewise, in the generic pharmaceutical area, proprietary protection, through patent, trade secret or other protection of our
enzymes and methods of producing a pharmaceutical product is important for us and our customers to maintain a lower cost production advantage over
competitors. As of December 31, 2012, we owned or controlled approximately 314 issued patents and approximately 338 pending patent applications in the
United States and in various foreign jurisdictions. These patents and patent applications are directed to our enabling technologies and specific methods and
products that support our business in the pharmaceutical and bioindustrial markets. The earliest that any of our intellectual property rights will expire is 2014.
The issued patents covering our fundamental shuffling technologies have terms ending as late as 2019. Our United States intellectual property rights directed
to our second generation enabling technologies have terms that expire from 2021 to 2024. We continue to file new patent applications, for which terms
generally extend 20 years from the filing date in the United States.

In October 2010, we acquired substantially all of the patents and other intellectual property rights associated with Maxygen, Inc.'s, or Maxygen, directed
evolution technology, known as the MolecularBreeding™ technology platform, including patents, trademarks, copyrights, software and certain assumed
contracts. Prior to this transaction, we and Maxygen were parties to a license agreement pursuant to which Maxygen granted us a worldwide, exclusive
license to certain Maxygen intellectual property related to the use of directed evolution technology in a variety of fields of use. Since we now own
substantially all of the intellectual property rights subject to the original license, the original license with Maxygen has been terminated. The intellectual
property rights and assets that we acquired from Maxygen will continue to be subject to existing license rights previously granted by Maxygen to third parties,
including Perseid Therapeutics LLC, or Perseid, and to Novozymes A/S, or Novozymes. Perseid retains exclusive licenses to use the intellectual property for
the discovery, research and development of protein pharmaceuticals. We and Novozymes enjoy co-exclusive rights in certain fields, including biofuels.
Novozymes did not receive a license to all of the rights we are using in biofuels applications and which we believe are critical to pursuing such applications.
Novozymes also has exclusive rights to certain of the intellectual property that we acquired from Maxygen in certain limited fields, including development,
production and sales of industrial proteins for use in processes for textile, garment, leather, wood and paper production, certain starch, food and animal feed
production, certain personal care products, oil drilling, dyestuffs and dyeing and electronics industry waste water treatment.

As part of the transaction with Maxygen, we entered into a new license agreement with Maxygen, pursuant to which we granted to Maxygen certain license
rights to the intellectual property assets that we acquired to the extent necessary for Maxygen to fulfill its contractual obligations under the license agreements
retained by Maxygen.

We will continue to file and prosecute patent applications and maintain trade secrets in an ongoing effort to protect our intellectual property. It is possible that
our current patents, or patents which we may later acquire, may be successfully challenged or invalidated in whole or in part. It is also possible that we may
not obtain issued patents from our pending patent applications or other inventions we seek to protect. We sometimes permit certain intellectual property to
lapse or go abandoned under appropriate circumstances. Due to uncertainties inherent in prosecuting patent applications, sometimes patent applications are
rejected and we subsequently abandon them. It is also possible that we may develop proprietary products or technologies in the future that are not patentable
or that the patents of others will limit or altogether preclude our ability to do business. In addition, any patent issued to us may provide us with little or no
competitive advantage, in which case we may abandon such patent or license it to another entity.

Our registered and pending United States and foreign trademarks include Codexis®, Codex®, CodeEvolver®, CodeXporter®, CodeXol®, CodeXyme®, Powered
by CodeEvolver™, Driving the New Sugar Economy™, We're Codexis. Proven Products. Real Results™, Bringing Life to Chemistry, and a Codexis and
design mark (i.e., the Codexis logo).

Our means of protecting our proprietary rights may not be adequate and our competitors may independently develop technology or products that are similar to
ours or that compete with ours. Patent, trademark, and trade secret laws afford only limited protection for our technology platform and products. The laws of
many countries do not protect our proprietary rights to as great an extent as do the laws of the United States. Despite our efforts to protect our proprietary
rights, unauthorized parties have in the past attempted, and may in the future attempt, to operate under aspects of our intellectual property or products or to
obtain and use information that we regard as proprietary. Third parties may also design around our proprietary rights, which may render our protected
technology and products less valuable, if the design around is favorably received in the marketplace.

In addition, if any of our products or technology is covered by third-party patents or other intellectual property rights, we could be subject to various legal
actions. We cannot assure you that our technology platform and products do not infringe patents held by others or that they will not in the future.

Litigation may be necessary to enforce our intellectual property rights, to protect our trade secrets, to determine the validity and scope of the proprietary rights
of others, or to defend against claims of infringement, invalidity, misappropriation, or other claims. Any such litigation could result in substantial costs and
diversion of our resources. Moreover, any settlement of or adverse judgment resulting from such litigation could require us to obtain a license to continue to
make, use or sell the products or technology that is the subject of the claim, or otherwise restrict or prohibit our use of the technology.

Competition

Overview

We are a leader in the field of directed molecular evolution of biocatalysts. We are aware that other companies, including DSM, E.I. DuPont De Nemours and
Company, or DuPont, and Vercipia Biofuels, an affiliate of BP p.l.c., have alternative methods for obtaining and generating genetic diversity or use
mutagenesis techniques to produce genetic diversity. Academic institutions such as the California Institute of Technology, the Max Planck Institute and the
Center for Fundamental and Applied Molecular Evolution (FAME), a jointly sponsored initiative between Emory University and Georgia Institute of
Technology, are also working in this field. This field is highly competitive and companies and academic and research institutions are actively seeking to
develop technologies that could be competitive with our technologies.

We are aware that other companies, organizations and persons have developed technologies that appear to have some similarities to our patented proprietary
technologies. In addition, academic institutions are also working in this field. Technological developments by others may result in our products and
technologies, as well as products developed by our customers using our biocatalysts, becoming obsolete. We monitor publications and patents that relate to
directed molecular evolution to be aware of developments in the field and evaluate appropriate courses of action in relation to these developments.

Many of our competitors have substantially greater manufacturing, financial, research and development, personnel and marketing resources than we do. In
addition, certain of our competitors may also benefit from local government subsidies and other incentives that are not available to us. As a result, our
competitors may be able to develop competing and/or superior technologies and processes, and compete more aggressively and sustain that competition over
a longer period of time than we could. Our technologies and products may be rendered obsolete or uneconomical by technological advances or entirely
different approaches developed by one or more of our competitors. As more companies develop new intellectual property in our markets, the possibility of a
competitor acquiring patent or other rights that may limit our products or potential products increases, which could lead to litigation.

We also face differing forms of competition in our various markets, as set forth below:

Pharmaceuticals

Our primary competitors in the pharmaceutical market are companies using conventional, non-enzymatic processes to manufacture pharmaceutical
intermediates and APIs that compete in the marketplace with our enzymatically manufactured products. The principal methods of competition and
competitive differentiation in this market are product quality and performance, including manufacturing yield and safety and environmental benefits, speed of
delivery of product and price. The market for the manufacture and supply of APIs and intermediates is large with many established companies. These
companies include many of our large innovator and generic pharmaceutical customers, such as Merck, Pfizer, and Teva, who have significant internal
research and development efforts directed at developing processes to manufacture APIs and intermediates. The processes used by these companies include
classical conventional organic chemistry reactions, chemo catalysis reactions catalyzed by chemical catalysts, or biocatalytic routes using commercially
available enzymes, or combinations thereof. Our manufacturing processes must compete with these internally developed routes. Additionally, there are many
large well-established fine chemical manufacturing companies that compete to supply pharmaceutical intermediate and APIs to our customers, such as DSM,
BASF Corporation and Lonza Group Ltd. Finally, we face increasing competition from generic pharmaceutical manufacturers in low cost centers such as
India and China.

In addition to competition from companies manufacturing intermediates and APIs, we face competition from companies that sell enzymes for use in the
pharmaceutical market. The market for supplying enzymes for use in pharmaceutical manufacturing is quite fragmented. There is competition from large
industrial enzyme companies, such as Novozymes and Amano Enzyme Inc., whose industrial enzymes (for detergents, for example) are occasionally used in
pharmaceutical processes. There is also competition in this area from several small European companies with relatively limited product offerings comprised
primarily

17

Table of Contents

of naturally occurring enzymes. In addition to these enzyme supply companies, there is a separate group of small companies, also predominately in Europe,
that offers enzyme optimization services.

We believe that our principal advantage is our ability to rapidly deliver customized enzyme products for existing and new intermediates and APIs in the
pharmaceuticals market. This capability has allowed us to create a breadth of products with improved performance characteristics including, for example,
activity, stability, and activity on a range of substrates, compared to traditional chemistry-based manufacturing processes and naturally occurring biocatalysts.
We believe that our directed evolution technology provides substantially superior results, in shorter time frames, than companies offering competing
biocatalyst development services.

Cellulases

Many established companies are developing cellulases that could potentially compete with CodeXyme® cellulase enzymes, including:

•

•

•

Novozymes, which has partnered with Gruppo Mossi & Ghisolfi, or M&G, in Italy to be the cellulase supplier to a commercial scale cellulosic
ethanol plant being built by M&G;

DuPont, which is marketing a line of cellulases to convert cellulosic biomass into sugar; and

DSM, which is developing cellulase enzymes and has formed a joint venture with POET, POET-DSM, to construct a facility to produce cellulosic
ethanol in Emmetsburg, Iowa.

Although few companies are currently converting cellulosic biomass into fermentable sugars on a commercial scale, many of our competitors have been
active in this area for many years, have invested significant resources in this effort, and have extensive patent portfolios regarding the relevant biocatalysts
and related processes. In addition, several companies are focused on developing non-biocatalytic, thermochemical processes to convert cellulosic biomass
into fermentable sugars. For example, Coskata, Inc. is developing a hybrid thermochemical-biocatalytic process to produce ethanol from a variety of
feedstocks. Our cellulases will need to be competitive with all of these alternative products on price and performance. New companies continue to enter this
marketplace. Many of these companies are actively developing and applying for intellectual property rights, including patent rights, in this space.

Detergent Alcohols

We announced CodeXol® detergent alcohols in 2011. We face competition in this market from Sasol, Shell, BASF, Kao Corporation and Liaoning Huaxing,
all of which have been active in the detergent alcohol marketplace for many years and have an established history with customers. We also face competition
from smaller companies that are developing biological routes to detergent alcohols, such as LS9, Inc.

 Operations

We conduct substantial operations outside of the United States. We have facilities in Redwood City, California and Budapest, Hungary. As of December 31,
2012, we employed 154 people worldwide, with 114 of our employees located in Redwood City. Please see Note 13 to our consolidated financial statements
appearing in Item 8 of this Annual Report on Form 10-K for a description of our revenue and long-lived assets outside of the United States.

Our corporate headquarters is located in Redwood City, California and provides general administrative support to our business and is the center of our
manufacturing and research and development operations. In 2008, we established our facilities in Budapest, Hungary to create a research and development
center for microbial biocatalyst improvement and fermentation development and to reduce our research and development costs. Hungary also has a highly
educated and skilled work force that leverages the long history of fermentation development in Eastern Europe. We closed our Singapore research and
development facility in 2012 as a result of restructuring activities following the termination of the Shell collaboration in August 2012. 

Our research and development operations include efforts directed towards biocatalyst evolution, bioprocess development, cellular engineering, biocatalyst
screening, metabolites, strain improvement, fermentation development and process engineering. We conduct enzyme evolution, enzyme production
development, microbial bioprocess development, cellular engineering, microbial evolution and process engineering evaluations and design primarily at our
headquarters in Redwood City. Our facility in Hungary collaborates with our headquarters in Redwood City in research and development activities relating to
microbe improvement and is our center of excellence for strain and fermentation development.

Table of Contents

We have limited internal manufacturing capacity at our headquarters in Redwood City. We expect to rely on third-party manufacturers for commercial
production of our biocatalysts for the foreseeable future. Our in-house manufacturing is dedicated to producing both Codex® Biocatalyst Panels and Kits and
enzymes for use by our customers in pilot scale production. We also supply initial commercial quantities of biocatalysts for use by our collaborators to
produce pharmaceutical intermediates and manufacture biocatalysts that we sell.

We rely on a contract manufacturer, Lactosan GmbH & Co. KG, or Lactosan, to manufacture substantially all of the commercial enzymes used in our
pharmaceutical business. We have qualified other contract manufacturers to manufacture biocatalysts for our pharmaceutical business, but we do not currently
rely on them for any of our supply requirements. We also contract with suppliers in Austria, Germany, Italy and India.

We intend to rely on contract manufacturers for the production of CodeXyme® cellulase enzymes for our biofuels and bio-based chemical businesses. We
expect to start a 1,500 liter CodeXol® detergent alcohols demonstration facility in Rivalta, Italy with our partner, Chemtex.

Customers

We rely on a limited number of customers for the majority of our current revenues. For the years ended December 31, 2010, 2011 and 2012, our top five
customers accounted for 85%, 77% and 81% of our total revenues, respectively. Customers with revenues of 10% or more of our total revenues in any of the
past three fiscal years consist of the following:

Following the termination of our Shell collaboration effective August 31, 2012, we do not expect to receive future collaboration revenues from Shell and do
not anticipate that Shell will represent a significant portion of our total revenue in future periods.

Employees

As of December 31, 2012, we had 154 employees worldwide. Of these employees, 99 were engaged in research and development, 20 were engaged in
manufacturing and operations, and 35 were engaged in general and administrative activities, respectively. None of our employees are represented by a labor
union, and we consider our employee relations to be good.

Corporate and Available Information

Our principal corporate offices are located at 200 Penobscot Drive, Redwood City, California 94063 and our telephone number is (650) 421-8100. We were
incorporated in Delaware in January 2002. Our internet address is www.codexis.com. We make available on our website, free of charge, our Annual Report
on Form 10-K, Quarterly Reports on Form 10-Q, Current Reports on Form 8-K and any amendments to those reports, as soon as reasonably practicable after
we electronically file such materials with, or furnish it to, the Securities Exchange Commission, or the SEC. Our SEC reports can be accessed through the
Investor Relations section of our internet website. The information found on our internet website is not part of this or any other report we file with or furnish
to the SEC.

ITEM 1A. RISK FACTORS

You should carefully consider the risks described below together with the other information set forth in this Annual Report on Form 10-K, which could
materially affect our business, financial condition or future results. The risks described below are not the only risks facing our company. Risks and
uncertainties not currently known to us or that we currently deem to be immaterial also may materially adversely affect our business, financial condition
and/or operating results.

We have a limited operating history and have recently experienced significant changes to our business, which may make it difficult to evaluate our
current business and predict our future performance.

Risks Relating to Our Business and Strategy

19

 
 
 
 
 
 
 
   
   
 
Table of Contents

Our company has been in existence since January 2002. From 2002 until 2005, our operations focused on organizing and staffing our company and
developing our technology platform. In 2005, we recognized our first revenues from product sales. Since 2005, we have continued to generate revenues, but
because our revenue growth has occurred in recent periods, our limited operating history may make it difficult to evaluate our current business and predict our
future performance. Additionally, since 2006, a major portion of our business revolved around our research and development collaboration with Shell with
respect to advanced biofuels, and the collaboration accounted for 62%, 51% and 51%, of our revenues in 2010, 2011 and 2012 respectively. The Shell
collaboration ended in August 2012 and we undertook a significant restructuring of our operations as a result and refocused our business on the
pharmaceuticals market. As a result of these changes in our business, and any changes to our business focus that we may make as we move forward, our
operating history in past periods may not provide much of a basis to evaluate our current business or predict our future performance. Any assessments of our
current business and predictions you make about our future success or viability may not be as accurate as they could be if we had a longer operating history or
if we had not experienced significant changes to our business. We have encountered and will continue to encounter risks and difficulties frequently
experienced by young companies in rapidly changing industries. If we do not address these risks successfully, our business will be harmed.

Our quarterly or annual operating results may fluctuate in the future. As a result, we may fail to meet or exceed the expectations of research analysts or
investors, which could cause our stock price to decline.

Our financial condition and operating results have varied significantly in the past and may continue to fluctuate from quarter to quarter and year to year in the
future due to a variety of factors, many of which are beyond our control. Factors relating to our business that may contribute to these fluctuations include the
following factors, as well as other factors described elsewhere in this report:

•

programs;

our ability to obtain substantial additional capital that may be necessary to expand our business;

our ability to maintain internal control over financial reporting;

charges to earnings as a result of any impairment of goodwill, intangible assets or other long-lived assets;

our ability to realize the expected benefits from the reduction in force we undertook at the end of August 2012;

our dependence on a limited number of customers;

our customers' ability to timely pay amounts owed to us;

our dependence on a limited number of products in our pharmaceutical business;

our reliance on one contract manufacturer for commercial scale production of substantially all of our enzymes;

our ability to develop and successfully commercialize new products for the pharmaceuticals market;

our relationships with, and dependence on, collaborators in our principal markets;

our ability to deploy our technology platform in new adjacent market spaces;

our dependence on, and the need to attract and retain key management and other personnel;

any adverse effects our recent restructuring plan may have on our ability to react to business developments and manage our business;

the success of our customers' pharmaceutical products in the market and the ability of such customers to obtain regulatory approvals for products
and processes;

our ability to control and to improve pharmaceutical product gross margins;

the ability of Arch to effectively market pharmaceutical products manufactured using our enzymes;

our ability to maintain license rights for commercial scale expression systems for cellulases;

the feasibility of commercializing biofuels and bio-based chemicals derived from cellulose;

fluctuations in the price of and demand for commodities that our enzymes and fermentation organisms can be employed to produce or for
substitute commodities;

the availability, cost and location of cellulosic biomass sources;

changes to existing biofuel regulations and policies;

our potential bio-based chemical products might not be approved or accepted by our customers;

our ability to independently develop, manufacture, market, sell and distribute commercial cellulase enzymes;

risks associated with the international aspects of our business;

our ability to integrate any businesses we may acquire with our business;

our ability to accurately report our financial results in a timely manner;

our ability to obtain, protect and enforce our intellectual property rights;

our ability to prevent the theft or misappropriation of our biocatalysts, the genes that code for our biocatalysts, know-how or technologies;

potential advantages that our competitors and potential competitors may have in securing funding or developing products;

business interruptions, such as earthquakes and other natural disasters;

public concerns about the ethical, legal and social ramifications of genetically engineered products and processes;

our ability to comply with laws and regulations;

our ability to properly handle and dispose of hazardous materials used in our business;

our ability to obtain and maintain governmental awards;

potential product liability claims;

the existence of government subsidies or regulation with respect to carbon dioxide emissions; and

our ability to use our net operating loss carryforwards to offset future taxable income.

Due to the various factors mentioned above, and others, the results of any prior quarterly or annual periods should not be relied upon as indications of our
future operating performance.

We have a history of net losses, such losses may increase due to the termination of our research and collaboration with Shell, and we may not achieve or
maintain profitability.

We have incurred net losses since our inception, including losses of $8.5 million, $16.6 million, and $30.9 million in 2010, 2011 and 2012, respectively. As of
December 31, 2012, we had an accumulated deficit of $215.6 million. To date, we have derived a substantial portion of our revenues from research and
development agreements with our collaborators, particularly Shell, who accounted for 62%, 51%, and 51% of our revenues in 2010, 2011, and 2012,
respectively. Our research and development collaboration with Shell terminated effective as of August 31, 2012, and we do not expect to receive further
collaboration revenue from Shell. If we are unable to enter into binding collaboration agreements with new partners for our advanced biofuels program, we
will have to suspend continued development of our CodeXyme® cellulase enzymes, our revenues will decline substantially and our net losses may increase. In
addition, some of our collaboration agreements provide for milestone payments and future royalty payments, which we will only receive if we and our
collaborators develop and commercialize products. We also may fund development of additional pharmaceutical and potential bioindustrial products,
including CodeXol® detergent alcohols. There can be no assurance that any of these products will become commercially viable or that we will ever achieve
profitability on a quarterly or annual basis. If we fail to achieve profitability, or if the time required to achieve profitability is longer than we anticipate, we
may not be able to continue our business. Even if we do achieve profitability, we may not be able to sustain or increase profitability on a quarterly or annual
basis.

Table of Contents

Our CodeXyme® cellulase enzymes and our CodeXol® detergent alcohols programs are heavily dependent on our ability to secure third-party funding, or
to identify and effect other strategic options with respect to those programs.

Our current business plans for CodeXyme® cellulase enzymes and CodeXol® detergent alcohols are heavily dependent on third-party funding. We previously
received significant funding for our advanced biofuels program from Shell under a collaborative research agreement. This agreement terminated effective as
of August 31, 2012. We are in early stage discussions with multiple parties about potential collaborations, but we cannot assure you that any of our
discussions will lead to collaborations or that any new collaboration will fully substitute for the termination of the Shell collaboration. Raizen and Shell
currently hold rights to use our cellulase enzyme technology in Brazil, which could complicate our efforts to secure funding from third parties for our
CodeXyme® cellulase program. We currently do not expect to receive development funding from Raízen to support our CodeXyme® cellulase enzyme
program. To date, we have self-funded all development work for our CodeXol® detergent alcohols program. We are seeking collaboration partners to assist us
with funding the development and commercialization of CodeXol® detergent alcohols. We are also exploring other strategic options with respect to both
programs. If we are unable to agree to terms with new collaborators that provide us with the financial assistance and infrastructure necessary for us to develop
and commercialize our products and execute our strategy with respect to CodeXyme® cellulase enzymes and CodeXol® detergent alcohols, or if we are unable
to identify and effect attractive strategic options for those programs, we may need to fund this development ourselves, which will have a material adverse
effect on our financial condition, or we may need to suspend the programs which may have a material adverse effect on our business and prospects.

We may need substantial additional capital in the future in order to expand our business.

Our future capital requirements may be substantial, particularly as we continue to develop our business, including investing in our CodeXyme® cellulase
enzymes and CodeXol® detergent alcohol business opportunities. Although we believe that, based on our current level of operations, our existing cash, cash
equivalents and marketable securities will provide adequate funds for ongoing operations, planned capital expenditures and working capital requirements for
at least the next 12 months, we may need additional capital if our current plans and assumptions change. Our need for additional capital will depend on many
factors, including the financial success of our pharmaceutical business, identifying business partners to fund our cellulase program and our CodeXol®
detergent alcohol program, or identifying other strategic options with respect to such programs, our spending to develop and commercialize new and existing
products, the effect of any acquisitions of other businesses, technologies or facilities that we may make or develop in the future, our spending on new market
opportunities, including bio-based chemicals, and the filing, prosecution, enforcement and defense of patent claims. If our capital resources are insufficient to
meet our capital requirements, and we are unable to enter into or maintain collaborations with partners that are able or willing to fund our development efforts
or commercialize any products that we develop or enable, we will have to raise additional funds to continue the development of our technology and products
and complete the commercialization of products, if any, resulting from our technologies. If future financings involve the issuance of equity securities, our
existing stockholders would suffer dilution. If we raise debt financing, we may be subject to restrictive covenants that limit our ability to conduct our
business. We may not be able to raise sufficient additional funds on terms that are favorable to us, if at all. If we fail to raise sufficient funds and fail to
generate sufficient revenues to achieve planned gross margins and to control operating costs, our ability to fund our operations, take advantage of strategic
opportunities, develop products or technologies, or otherwise respond to competitive pressures could be significantly limited. If this happens, we may be
forced to delay or terminate research or development programs or the commercialization of products resulting from our technologies, curtail or cease
operations or obtain funds through collaborative and licensing arrangements that may require us to relinquish commercial rights, or grant licenses on terms
that are not favorable to us. If adequate funds are not available, we will not be able to successfully execute our business plan or continue our business.

We have determined that we had a material weakness in internal control over financial reporting as of December 31, 2012, which could, if not
remediated, adversely impact the reliability of our financial reports, cause us to submit our financial reports in an untimely fashion, result in material
misstatements in our financial statements and cause current and potential stockholders to lose confidence in our financial reporting, which in turn could
adversely affect the trading price of our common stock.

Section 404 of the Sarbanes-Oxley Act of 2002 requires companies to conduct a comprehensive evaluation of their disclosure controls and procedures over
financial reporting. At the end of each fiscal year, we must perform an evaluation of our disclosure controls and procedures over financial reporting, include
in our annual report the results of the evaluation, and have our external auditors publicly attest to such evaluation.

In connection with the integrated audit of our consolidated financial statements and internal control over financial reporting and management's assessment of
our internal controls over financial reporting at December 31, 2012, a material weakness in our internal control over financial reporting was identified. The
material weakness we identified relates to the lack of a sufficient number of qualified personnel to timely and appropriately account for complex, non-routine
transactions in accordance with

22

Table of Contents

United States generally accepted accounting principles. Examples of these significant non-routine transactions include, but are not limited to, complicated
revenue recognition transactions and complex contractual arrangements.

As a result of the restructuring activities following the termination of the Shell collaboration in August 2012, we experienced significant turnover in our
finance and accounting management. Notwithstanding the use of contract personnel and external consultants, our inability to attract, train, manage and retain
qualified finance and accounting personnel negatively impacted our ability to appropriately address complex, non-routine transactions.

A material weakness is defined as a deficiency, or combination of deficiencies, in internal control over financial reporting such that there is a reasonable
possibility that a material misstatement of annual or interim consolidated financial statements will not be prevented or detected on a timely basis. As a result
of the material weakness described above, we have concluded our internal control over financial reporting was not effective at December 31, 2012 based on
the guidelines established in Internal Control-Integrated Framework issued by the Committee of Sponsoring Organizations of the Treadway Commission
(COSO).

We have not yet been able to remediate this material weakness. We do not know the specific timeframe needed to remediate all of the control deficiencies
underlying this material weakness. In addition, we may need to incur incremental costs associated with this remediation, primarily due to the hiring of finance
and accounting personnel, and the implementation and validation of improved accounting and financial reporting procedures. If we are not successful in
remediating the material weakness, or if we determine in future fiscal periods that we have additional material weaknesses in our internal control over
financial reporting, the reliability of our financial reports may be adversely impacted, we may be unable to submit our reports in a timely fashion and we
could be required to restate our financial results. This could cause current and potential stockholders to lose confidence in our financial reporting, which could
adversely affect the trading price of our common stock.

If goodwill or our intangible or other long-lived assets become impaired we may be required to record a significant charge to earnings.

Our total assets reflect substantial goodwill, intangible assets and other long-lived assets. Under accounting principles generally accepted in the United States,
or GAAP, we review goodwill for impairment on at least an annual basis and at any interim date whenever events or changes in circumstances indicate that
the carrying value may not be recoverable. We review our long lived and intangible assets with finite lives for impairment whenever events or changes in
circumstances indicate that the carrying amount of the assets may not be recoverable. Events or changes in circumstances (i.e., information that indicates an
impairment might exist), could include: a significant decrease in the market price of the Company's common stock; current period cash flow losses or
operating losses combined with a history of losses or a forecast of continuing losses associated with the use of the assets; slower growth rates in our industry;
significant adverse changes in the business climate or legal factors; accumulation of costs significantly in excess of the amount originally expected for the
acquisition or construction of the assets; loss of significant customers or partners; or the current expectation that the assets will more likely than not be sold or
disposed of significantly before the end of their estimated useful life. We may be required to record a significant charge to earnings in our financial statements
during the period in which any impairment of our goodwill, intangible assets or other long-lived assets is determined, resulting in an adverse impact on our
financial position and results of operations.

We implemented cost saving measures in the third and fourth quarters of 2012 and may implement additional cost saving measures in the future. These
measures may interfere with the operation of our business and if we are unable to realize the anticipated benefits of these measures, our operating results
and financial condition could be adversely affected.

In the third and fourth quarters of 2012, we implemented a reduction in our global workforce and implemented other cost savings measures to reduce our cash
expenditures. These measures included the termination of approximately 55% of our global workforce and the closing of our Singapore facility. We are also
in the process of vacating one of our facilities in Redwood City, California and attempting to sublease it. If we are unable to realize the expected operational
efficiencies and financial benefits from this workforce reduction, or if we are unable to sublease the vacated facility, our operating results and financial
condition would be adversely affected. Restructuring costs include expenses related to severance for terminated employees and other exit-related costs arising
from contractual and other obligations. We continue to review our cost structure and may implement further cost saving initiatives in the future. These cost
reduction efforts may interfere with our ability to achieve our business objectives, may be difficult to manage, may cause concerns from current and potential
customers, suppliers and other third parties with whom we do business and may increase the likelihood of turnover of other key employees, all of which may
have an adverse impact on our business.

We are dependent on a limited number of customers.

Our current revenues are derived from a limited number of key customers. For the year ended December 31, 2011, our top five customers accounted for 77%
of our total revenues, with Shell accounting for 51% of our total revenues. For the year ended December 31, 2012, our top five customers accounted for 81%
of our total revenues, with Shell accounting for 51% of our total

23

Table of Contents

revenues. Our research collaboration with Shell terminated effective as of August 31, 2012, which means that we will not receive any additional collaboration
funding from Shell. We expect a limited number of customers to continue to account for a significant portion of our revenues for the foreseeable future. This
customer concentration increases the risk of quarterly fluctuations in our revenues and operating results. The loss of business from Shell will, and the loss or
reduction from one or a combination of our other significant customers could, materially adversely affect our revenues, financial condition and results of
operations.

Our revenues, financial condition and results of operations may also be adversely affected if one or more of our customers is delayed in paying, or
becomes unable to pay, for our delivered products on a timely basis.

Certain of our customers are, or in the future may become, subject to significant economic and other challenges that affect their cash flow, and many
customers outside of the United States are generally accustomed to vendor financing in the form of extended payment terms which may exceed contractual
payment terms.  To remain competitive in markets outside of the United States, we may offer selected customers such payment flexibility.  We consider
arrangements with extended payment terms not to be fixed or determinable, and accordingly, we defer revenue until payment is received.  The costs
associated with such revenue deferral are also deferred and classified as other current assets in the financial statements. If these customers fail to pay us on a
timely basis it may cause our financial results to fluctuate and we may decide to grant concessions to such customers to increase the probability of payment.
Such concessions, or failure by such customers to pay at all, would adversely impact our financial condition and results of operations.

We are dependent on a limited number of products in our pharmaceutical business.

Our current product revenues are derived from a limited number of pharmaceutical products. For the year ended December 31, 2012, we derived 78% of our
product revenue from two pharmaceutical product families: statins and hepatitis C therapies. We expect a limited number of pharmaceutical products to
continue to account for a significant portion of our pharmaceutical product revenues for the foreseeable future. This product concentration increases the risk
of quarterly fluctuations in our revenues and operating results. The loss or reduction of business of one or a combination of our significant pharmaceutical
products could materially adversely affect our revenues, financial condition and results of operations.

We are dependent on contract manufacturers for commercial scale production of substantially all of our enzymes.

We have limited internal capacity to manufacture enzymes. As a result, we are dependent upon the performance and capacity of third party manufacturers for
the commercial scale manufacturing of the enzymes used in our pharmaceutical and cellulase businesses.

We rely on one contract manufacturer, Lactosan, for our pharmaceutical business to manufacture substantially all of the commercial enzymes used in our
pharmaceutical business. Our pharmaceutical business, therefore, faces risks of difficulties with, and interruptions in, performance by Lactosan, the
occurrence of which could adversely impact the availability, launch and/or sales of our enzymes in the future. We have qualified other contract manufacturers
to manufacture enzymes for our pharmaceutical business, but currently have limited reliance on them for our supply requirements. The failure of any contract
manufacturers that we may use to supply manufactured enzymes on a timely basis or at all, or to manufacture our enzymes in compliance with our
specifications or applicable quality requirements or in volumes sufficient to meet demand would adversely affect our ability to sell pharmaceutical products,
could harm our relationships with our collaborators or customers and could negatively affect our revenues and operating results. We may be forced to secure
alternative sources of supply, which may be unavailable on commercially acceptable terms, cause delays in our ability to deliver products to our customers,
increase our costs and decrease our profit margins.

We do not have any supply agreements in place with any enzyme contract manufacturers, other than Lactosan. In the absence of a supply agreement, a
contract manufacturer will be under no obligation to manufacture our enzymes and could elect to discontinue their manufacture at any time. If we require
additional manufacturing capacity and are unable to obtain it in sufficient quantity, we may not be able to increase our pharmaceutical sales, or we may be
required to make substantial capital investments to build that capacity or to contract with other manufacturers on terms that may be less favorable than the
terms we currently have with our suppliers. If we choose to build our own additional manufacturing facility, it could take two years or longer before our
facility is able to produce commercial volumes of our enzymes. Any resources we expend on acquiring or building internal manufacturing capabilities could
be at the expense of other potentially more profitable opportunities. In addition, if we contract with other manufacturers, we may experience delays of several
months in qualifying them, which could harm our relationships with our collaborators or customers and could negatively affect our revenues or operating
results.

We also expect to use contract manufacturers to produce our cellulase enzymes and any products we may manufacture for the fine chemical markets. These
businesses will encounter similar risks in engaging contract manufacturers as our pharmaceutical business in the event we elect to use contract manufacturers.

If we are unable to develop and commercialize new products for the pharmaceutical market, our business and prospects will be harmed.

We plan to launch new products for the pharmaceutical market. These efforts are subject to numerous risks, including the following:

•

•

•

•

•

•

•

•

•

•

pharmaceutical companies may be reluctant to adopt new manufacturing processes that use our enzymes;

we may be unable to successfully develop the enzymes or manufacturing processes for our products in a timely and cost-effective manner, if at
all;

we may face difficulties in transferring the developed technologies to our customers and the contract manufacturers that we may use for
commercial scale production of intermediates and enzymes;

the contract manufacturers that we may use may be unable to scale their manufacturing operations to meet the demand for these products and we
may be unable to secure additional manufacturing capacity;

customers may not be willing to purchase these products for the pharmaceutical market from us on favorable terms, if at all;

we may face product liability litigation, unexpected safety or efficacy concerns and pharmaceutical product recalls or withdrawals;

changes in laws or regulations relating to the pharmaceutical industry could cause us to incur increased costs of compliance or otherwise harm our
business;

our customers' pharmaceutical products may experience adverse events or face competition from new products, which would reduce demand for
our products;

we may face pressure from existing or new competitive products; and

we may face pricing pressures from existing or new competitors, some of which may benefit from government subsidies or other incentives.

We are dependent on our collaborators, and our failure to successfully manage these relationships could prevent us from developing and commercializing
many of our products and achieving or sustaining profitability.

Our ability to maintain and manage collaborations in our markets is fundamental to the success of our business. We currently have license agreements,
research and development agreements, supply agreements and/or distribution agreements with various collaborators. We may have limited or no control over
the amount or timing of resources that any collaborator is able or willing to devote to our partnered products or collaborative efforts. Any of our collaborators
may fail to perform its obligations. These collaborators may breach or terminate their agreements with us or otherwise fail to conduct their collaborative
activities successfully and in a timely manner. Further, our collaborators may not develop products arising out of our collaborative arrangements or devote
sufficient resources to the development, manufacture, marketing, or sale of these products. Moreover, disagreements with a collaborator could develop and
any conflict with a collaborator could reduce our ability to enter into future collaboration agreements and negatively impact our relationships with one or
more existing collaborators. If any of these events occur, or if we fail to maintain our agreements with our collaborators, we may not be able to commercialize
our existing and potential products, grow our business, or generate sufficient revenues to support our operations. Our collaboration opportunities could be
harmed if:

•

•

•

we do not achieve our research and development objectives under our collaboration agreements in a timely manner or at all;

we develop products and processes or enter into additional collaborations that conflict with the business objectives of our other collaborators;

we disagree with our collaborators as to rights to intellectual property that are developed during the collaboration, or their research programs or
commercialization activities;

25

Table of Contents

•

•

•

•

we are unable to manage multiple simultaneous collaborations;

our collaborators become competitors of ours or enter into agreements with our competitors;

our collaborators become unable or less willing to expend their resources on research and development or commercialization efforts due to
general market conditions, their financial condition or other circumstances beyond our control; or

our collaborators experience business difficulties, which could eliminate or impair their ability to effectively perform under our agreements.

Additionally, despite the termination of the research term of our three-way research collaboration with Shell and Iogen, many elements of our collaborative
research and license agreement with Shell and Iogen will continue. For example, the collaborative research and license agreement provides for certain rights,
licenses and obligations of each party with respect to intellectual property and program materials that will continue after the research activities have ended.
Disagreements or conflicts between and among the parties could develop even though the research program has ended. These disagreements or conflicts
could result in expensive arbitration or litigation, which may not be resolved in our favor.

Finally, our business could be negatively affected if any of our collaborators or suppliers undergo a change of control or were to otherwise assign the rights or
obligations under any of our agreements.

Our efforts to deploy our technology platform in adjacent market spaces, such as fine chemicals and therapeutic enzymes, may fail.

We are exploring whether to use our CodeEvolver® directed evolution technology platform to develop new products in several new adjacent market spaces,
including fine chemicals and therapeutic enzymes. We do not know if we can successfully compete in these new market opportunities. Each of these new
markets is well established and consists of numerous large, well-funded entrenched market participants who have long and established track records and
customer relationships. If we develop new products to introduce into one or more of these new markets, we may not succeed in displacing current products. If
we succeed in commercializing these new products, we may not generate significant revenue and cashflows from these activities. The failure to successfully
deploy products in these new market spaces may limit our growth and have a material adverse effect on our financial condition, operating results and business
prospects.

If we lose key personnel, including key management personnel, or are unable to attract and retain additional personnel as needed in the future, it could
disrupt the operation of our business, delay our product development programs, harm our research and development efforts, and we may be unable to
pursue collaborations or develop our own products.

Our business involves complex, global operations across a variety of markets and requires a management team and employee workforce that is
knowledgeable in the many areas in which we operate. The loss of any key members of our management team or the failure to attract or retain other key
employees who possess the requisite expertise for the conduct of our business could prevent us from developing and commercializing our products for our
target markets and entering into collaborations or licensing arrangements to execute on our business strategy.

In addition, the loss of any key scientific staff, or the failure to attract or retain other key scientific employees, could prevent us from developing and
commercializing our products for our target markets and entering into collaborations or licensing arrangements to execute on our business strategy. We may
not be able to attract or retain qualified employees in the future due to the intense competition for qualified personnel among biotechnology and other
technology-based businesses, particularly in the areas of biofuels and bio-based chemicals, or due to the availability of personnel with the qualifications or
experience necessary for our business. Additionally, potential future government awards may require us to maintain a minimum level of staffing. If we are not
able to attract and retain the necessary personnel to accomplish our business objectives, we may experience staffing constraints that will adversely affect our
ability to meet the demands of our collaborators and customers in a timely fashion or to support our internal research and development programs. In
particular, our product and process development programs are dependent on our ability to attract and retain highly skilled scientists and engineers.
Competition for experienced scientists and other technical personnel from numerous companies and academic and other research institutions may limit our
ability to do so on acceptable terms. All of our employees are at-will employees, which means that either the employee or we may terminate their
employment at any time.

Our planned activities will require additional expertise in specific industries and areas applicable to the products and processes developed through our
technology platform or acquired through strategic or other transactions, especially in the end markets that we seek to penetrate. These activities will require
the addition of new personnel, and the development of additional

26

Table of Contents

expertise by existing personnel. The inability to attract personnel with appropriate skills or to develop the necessary expertise could impair our ability to grow
our business.

In August and September 2012, we implemented a corporate restructuring plan that included a reduction in work force of approximately 55% of our total
workforce and the closure of one of our overseas offices. The restructuring and reductions in workforce have had and may continue to have a negative effect
on employee morale, and we may have difficulty in attracting and retaining qualified personnel.

Our business could be adversely affected if our customers' pharmaceutical products are not received well in the market, if their pharmaceutical products,
or the processes used by our customers to manufacture their final pharmaceutical products, fail to be approved, or if our customers discontinue their
drug development activities for any reason.

Our enzymes are used in the manufacture of intermediates and APIs which are then used in the manufacture of final pharmaceutical products by our existing
and potential branded drug customers. Our business could be adversely affected if these final pharmaceutical products do not perform in the market as well as
expected, or if our customers encounter competition from new entrants into the market with competing, and possibly superior, pharmaceutical products.
Additionally, these pharmaceutical products must be approved by the FDA in the United States and similar regulatory bodies in other markets prior to
commercialization. If our customers who sell branded-drugs, which we refer to as innovators, fail to receive regulatory approval for the drugs, fail to receive
regulatory approval for new manufacturing processes for previously approved drugs, or decide for business or other reasons to discontinue their drug
development activities, our revenues and prospects will be negatively impacted. The process of producing these drugs, and their generic equivalents, is also
subject to regulation by the FDA in the United States and equivalent regulatory bodies in other markets. If any pharmaceutical process that uses our enzymes
does not receive approval by the appropriate regulatory body or if customers decide not to pursue approval, our business could be adversely affected.

Our pharmaceutical product gross margins are variable and may decline from quarter to quarter.

Our pharmaceutical product gross margins have varied significantly in the past and may continue to fluctuate from quarter to quarter and year to year in the
future due to a variety of factors, including product mix, pricing pressure from our pharmaceutical customers and competition from other products or
technologies. This variability may have a material adverse impact on our operating results and financial condition and cause our stock price to decline.

Our generic pharmaceutical business is partially dependent on Arch's ability to effectively market and sell certain pharmaceutical products.

Under the New Arch Enzyme Supply Agreement, we sell enzymes to Arch that it uses to manufacture APIs and intermediates that it sells to pharmaceutical
companies worldwide. A portion of our pharmaceuticals product revenues are dependent on Arch's ability to market and sell APIs and intermediates that are
made by Arch using our enzymes. We cannot control Arch's level of activity or expenditures relating to the marketing of such pharmaceutical products
relative to the rest of their products or marketing efforts. Arch may fail to effectively market these pharmaceutical products. Conflicting priorities, competing
demands or other factors that we cannot control, and of which we may not be aware, may cause Arch to deemphasize such pharmaceutical products. If Arch
does not successfully promote these pharmaceutical products in the marketplace, this could have an adverse impact on our pharmaceutical business and our
revenues and operating results.

If we are unable to maintain license rights to a commercial scale expression system for enzymes that convert cellulosic biomass to sugars, our business
may be materially adversely affected.

We entered into a license agreement with Dyadic International, Inc. and its affiliate, or Dyadic, in November 2008 to obtain access to an expression system
and the enzymes that convert cellulosic biomass to sugars. Under the license agreement with Dyadic, we obtained a non-exclusive license under intellectual
property rights of Dyadic relating to Dyadic's proprietary fungal expression technology for the production of enzymes and to the cellulase enzymes. We also
obtained access to specified materials of Dyadic relating to such Dyadic technology. Our license is sublicenseable to Shell and to affiliates of Shell in the field
of biofuels. Dyadic has the right to terminate our licenses under the license agreement if we challenge the validity of any of the patents licensed under the
license agreement and for various other reasons. Our licenses and access to such materials of Dyadic under the license agreement will terminate as a result of
any termination of the license agreement other than due to Dyadic's material breach. If we are unable to maintain these rights on commercially reasonable
terms or if the license agreement is terminated for any reason, we will need to buy or license this type of expression system from another party or develop this
type of expression system ourselves, which may be difficult, costly and time consuming, in part because of the broad, existing intellectual property rights
owned by Novozymes and E.I. Du Pont De Nemours and Company, or DuPont, and others. If any of these events occur, our business may be materially
adversely affected.

Commercialization of biofuels and bio-based chemicals derived from cellulose may not be feasible.

We are developing CodeXyme® cellulase enzymes for use in producing advanced biofuels and bio-based chemicals. However, production and
commercialization of cellulosic biofuels and bio-based chemicals may not be feasible for a variety of reasons. For example, the development of technology
for converting sugar derived from cellulosic biomass into a commercially viable biofuel or bio-based chemical is still unproven, and we do not know whether
this can be done commercially and profitably. We believe that there are very few commercial scale cellulosic biofuel and cellulosic bio-based chemicals
production plants in operation. There can be no assurance that anyone will be able or willing to successfully develop and operate these production plants at
commercial scale or that any of these facilities can be profitable. Additionally, if existing tax credits, subsidies and other incentives in the United States and
foreign markets are phased out or reduced, the overall cost of commercialization of cellulosic biofuels will increase.

Fluctuations in the price of and demand for certain commodities may reduce demand for the commercial products that use our technology, thus reducing
demand for our technology.

Biofuels and some bio-based chemicals are anticipated to be marketed as an alternative to fossil fuel-based products. Therefore, if the price of natural gas or
oil falls, any revenues that we generate from biofuel or bio-based chemical products could decline, and we may be unable to produce products that are a
commercially viable alternative to fossil fuel-based products. For instance, implementation of and advances in hydraulic fracturing technology for the
production of natural gas from shale has increased the availability of, and decreased the price of, natural gas in recent years. Additionally, demand for liquid
transportation fuels, including biofuels, may decrease due to economic conditions or otherwise. Demand for bio-based chemicals may also decrease if the
price of natural gas or oil decreases. Similarly, CodeXyme® cellulase enzymes are used in producing fermentable sugars, which are anticipated to be marketed
as an alternative to fermentable sugars from sugar and starch food sources, such as corn and sugar cane. Therefore, if the price of sugar falls, the demand for
CodeXyme® cellulase enzymes, may fall, and we may be unable to produce cellulase enzymes for use in producing fermentable sugars that are a
commercially viable alternative to fermentable sugars from sugar and starch food sources.

Our biofuel and bio-based chemical business opportunities may be limited by the availability, cost or location of feedstocks.

Our business opportunities in the biofuel and bio-based chemical markets may be dependent on the availability and price of feedstocks, including sugar,
starch and cellulosic biomass. If the availability of these feedstocks decreases or their price increases, this may reduce the desirability of our biofuel and bio-
based chemical products and have a material adverse effect on our financial condition and operating results. At certain levels, prices may make these products
uneconomical to use and produce.

The price and availability of feedstocks may be influenced by general economic, market and regulatory factors. These factors include the availability of arable
land to supply feedstock, weather conditions, farming decisions, logistics for collection and storage of cellulosic biomass, government policies and subsidies
with respect to agriculture and international trade, and global demand and supply. The significance and relative impact of these factors on the price of
feedstocks is difficult to predict, especially without knowing what types of feedstocks we may need to use.

Our current business plan for the biofuel and bio-based chemical markets is to leverage our primary competitive strength, which we believe is our ability to
optimize the performance of CodeXyme® cellulase enzymes rapidly for varying feedstocks and process conditions. While CodeXyme® cellulase enzymes may
perform well on specific feedstocks and under certain process conditions, it might not perform well on other feedstocks or process conditions. If CodeXyme®
cellulase enzymes do not perform as planned on our customers' feedstocks, our business may be adversely affected.

Changes to existing biofuel regulations and policies may present technical, regulatory and economic barriers, all of which may significantly reduce
demand for biofuels.

The market for biofuels is heavily influenced by foreign, federal, state and local government regulations and policies concerning the petroleum industry. In
2007, the United States Congress passed an alternative fuels mandate that currently calls for approximately 36 billion gallons of liquid transportation fuels
sold in 2022 to come from alternative sources, including biofuels. Of this amount, a minimum of 21 billion gallons must be advanced biofuels, with 16 billion
gallons of that to be cellulosic derived. In the United States and a number of other countries, these regulations and policies have been modified in the past and
may be modified again in the future. For example, the United States Environmental Protection Agency has the authority to adjust or reduce the gallon
milestones of the alternative fuels mandate to reflect the marketplace supply availability. Any reduction in mandated requirements for fuel alternatives and
additives to gasoline may cause demand for biofuels to decline and deter investment in the research and development of biofuels. Congressional and market
uncertainty regarding future policies will affect our ability to develop new biofuels products or to license our technologies to third parties. Any inability to
address these requirements and any regulatory or policy changes could have a material adverse effect on our

28

Table of Contents

biofuels business, financial condition and operating results. Our other potential bioindustrial products may be subject to additional regulations. Adoption of
E15 (15% ethanol blend) in the United States may also be a significant factor in commercialization of cellulosic ethanol. The United States Environmental
Protection Agency granted final approval for the sale of E15 on June 15, 2012. However, federal, state and local governments have yet to determine their role
in providing infrastructure support to aid retailers in installing, or replacing, fuel pumps that are required for E15. Installation of such pumps is an option, not
a requirement, and if it is not adopted in the coming years it may limit the future demand for both corn-based and cellulosic ethanol in the United States.

Our potential bio-based chemical products may not be approved or accepted by customers.

We have only recently entered the market for bio-based chemical products used by large consumer products or chemical companies through our collaboration
with Chemtex, a subsidiary of Gruppo Mossi & Ghisolfi. In entering this market, we intend to sell CodeXol® detergent alcohols as an alternative to chemicals
currently in use, and in some cases the chemicals that we seek to replace have been used for many years. The potential customers for our bio-based chemical
products generally have well developed manufacturing processes and arrangements with suppliers of the chemical components of their products and may
resist changing these processes and components. These potential customers frequently impose lengthy and complex product qualification procedures on their
suppliers. Factors that these potential customers consider during the product qualification process include consumer preference, manufacturing considerations
such as process changes and capital and other costs associated with transitioning to alternative components, supplier operating history, regulatory issues,
product liability and other factors, many of which are unknown to, or not well understood by, us. Satisfying these processes may take many months or years.
If we are unable to convince these potential customers that our products are comparable to the chemicals that they currently use or that the use of our products
produces benefits to them, we will not be successful in these markets and our business will be adversely affected. Additionally, in contrast to the tax
incentives relating to biofuels, tax credits and subsidies are not currently available in the United States for consumer products or chemical companies who use
our bio-based chemical products.

We face risks associated with our international business.

Significant portions of our operations are conducted outside of the United States and we expect to continue to have significant foreign operations in the
foreseeable future. International business operations are subject to a variety of risks, including:

•

•

•

•

•

•

•

•

•

•

•

changes in or interpretations of foreign regulations that may adversely affect our ability to sell our products, repatriate profits to the United States
or operate our foreign-located facilities;

the imposition of tariffs;

the imposition of limitations on, or increase of, withholding and other taxes on remittances and other payments by foreign subsidiaries or joint
ventures;

the imposition of limitations on genetically-engineered products or processes and the production or sale of those products or processes in foreign
countries;

currency exchange rate fluctuations;

uncertainties relating to foreign laws, regulations and legal proceedings including tax, import/export, anti-corruption and exchange control laws;

the availability of government subsidies or other incentives that benefit competitors in their local markets that are not available to us;

increased demands on our limited resources created by our diversified, global operations may require us to expand the capabilities of our
administrative and operational resources and to attract, train, manage and retain qualified management, technicians, scientists and other personnel
which we may be unable to do effectively;

economic or political instability in foreign countries;

difficulties associated with staffing and managing foreign operations; and

the need to comply with a variety of United States and foreign laws applicable to the conduct of international business, including import and
export control laws and anti-corruption laws.

In 2011, we began doing business in Brazil and we will likely need to secure licenses, permits or other governmental approvals in order to use our technology
there. The failure to obtain any applicable licenses, permits or other governmental approvals could delay or prevent the deployment of our technology in
Brazil.

If we engage in any acquisitions, we will incur a variety of costs and may potentially face numerous risks that could adversely affect our business and
operations.

We have made acquisitions in the past, and if appropriate opportunities become available, we expect to acquire additional businesses, assets, technologies, or
products to enhance our business in the future. For example, in October 2010, we acquired substantially all of the patents and other intellectual property rights
associated with Maxygen's directed evolution technology. In connection with any future acquisitions, we could:

•

•

•

•

issue additional equity securities, which would dilute our current stockholders;

incur substantial debt to fund the acquisitions;

use our cash to fund the acquisitions; or

assume significant liabilities including litigation risk.

Acquisitions involve numerous risks, including problems integrating the purchased operations, technologies or products, unanticipated costs and other
liabilities, diversion of management's attention from our core businesses, adverse effects on existing business relationships with current and/or prospective
collaborators, customers and/or suppliers, risks associated with entering markets in which we have no or limited prior experience and potential loss of key
employees. We do not have extensive experience in managing the integration process and we may not be able to successfully integrate any businesses, assets,
products, technologies, or personnel that we might acquire in the future without a significant expenditure of operating, financial and management resources, if
at all. The integration process could divert management's time from focusing on operating our business, result in a decline in employee morale and cause
retention issues to arise from changes in compensation, reporting relationships, future prospects or the direction of the business. Acquisitions may also require
us to record goodwill and non-amortizable intangible assets that will be subject to impairment testing on a regular basis and potential periodic impairment
charges, incur amortization expenses related to certain intangible assets, and incur large and immediate write offs and restructuring and other related
expenses, all of which could harm our operating results and financial condition. In addition, we may acquire companies that have insufficient internal
financial controls, which could impair our ability to integrate the acquired company and adversely impact our financial reporting. If we fail in our integration
efforts with respect to any of our acquisitions and are unable to efficiently operate as a combined organization, our business and financial condition may be
adversely affected.

We must rely on our suppliers, contract manufacturers and customers to deliver timely and accurate information in order to accurately report our
financial results in the time frame and manner required by law.

We need to receive timely, accurate and complete information from a number of third parties in order to accurately report our financial results on a timely
basis. We rely on suppliers and certain contract manufacturers to provide us with timely and accurate information regarding our inventories and
manufacturing cost information, and we rely on current and former collaborators to provide us with product sales and cost saving information in connection
with royalties owed to us. Any failure to receive timely information from one or more of these third parties could require that we estimate a greater portion of
our revenues and other operating performance metrics for the period, which could cause our reported financial results to be incorrect. Moreover, if the
information that we receive is not accurate, our financial statements may be materially incorrect and may require restatement, and we may not receive the full
amount of revenues that we are entitled to under these arrangements. Although we typically have audit rights with these parties, performing such an audit
could be harmful to our collaborative relationships, expensive and time consuming and may not be sufficient to reveal any discrepancies in a timeframe
consistent with our reporting requirements.

Our ability to compete may decline if we do not adequately protect our proprietary technologies or if we lose some of our intellectual property rights.

Our success depends in part on our ability to obtain patents and maintain adequate protection of our intellectual property for our technologies and products
and potential products in the United States and other countries. We have adopted a strategy of seeking patent protection in the United States and in foreign
countries with respect to certain of the technologies used in or relating to our products and processes. As such, as of December 31, 2012, we owned or
controlled approximately 314 issued patents and approximately 338 pending patent applications in the United States and in various foreign jurisdictions.
Some of our gene shuffling patents will expire as early as 2014. We also have license rights to a number of issued patents and pending

30

Table of Contents

patent applications in the United States and in various foreign jurisdictions. Our owned and licensed patents and patent applications are directed to our
enabling technologies and to the methods and products that support our business in the pharmaceuticals manufacturing, biofuels and bio-based chemicals
markets. We intend to continue to apply for patents relating to our technologies, methods and products as we deem appropriate.

Numerous patents in our portfolio involve complex legal and factual questions and, therefore, enforceability cannot be predicted with any certainty. Issued
patents and patents issuing from pending applications may be challenged, invalidated, or circumvented. Moreover, the United States Leahy-Smith America
Invents Act, enacted in September 2011, brings significant changes to the United States patent system, which include a change to a “first to file” system from
a “first to invent” system and changes to the procedures for challenging issued patents and disputing patent applications during the examination process,
among other things. The effects of these changes on our patent portfolio and business have yet to be determined, as the final substantive provisions of the
America Invents Act took effect on March 16, 2013, the United States Patent and Trademark Office only recently finalized the rules relating to these changes
and the courts have yet to address the new provisions. These changes could increase the costs and uncertainties surrounding the prosecution of our patent
applications and the enforcement or defense of our patent rights. Additional uncertainty may result from legal precedent handed down by the United States
Federal Circuit Court and Supreme Court as they determine legal issues concerning the scope and construction of patent claims and inconsistent interpretation
of patent laws by the lower courts. Accordingly, we cannot ensure that any of our pending patent applications will result in issued patents, or even if issued,
predict the breadth of the claims upheld in our and other companies' patents. Given that the degree of future protection for our proprietary rights is uncertain,
we cannot ensure that: (i) we were the first to invent the inventions covered by each of our pending applications, (ii) we were the first to file patent
applications for these inventions, or (iii) the proprietary technologies we develop will be patentable. In addition, unauthorized parties may attempt to copy or
otherwise obtain and use our products or technology. Monitoring unauthorized use of our intellectual property is difficult, and we cannot be certain that the
steps we have taken will prevent unauthorized use of our technology, particularly in certain foreign countries where the local laws may not protect our
proprietary rights as fully as in the United States. Moreover, third parties could practice our inventions in territories where we do not have patent protection.
Such third parties may then try to import products made using our inventions into the United States or other territories. If competitors are able to use our
technology, our ability to compete effectively could be harmed. Moreover, others may independently develop and obtain patents for technologies that are
similar to or superior to our technologies. If that happens, we may need to license these technologies, and we may not be able to obtain licenses on reasonable
terms, if at all, which could cause harm to our business.

Third parties may claim that we are infringing their intellectual property rights or other proprietary rights, which may subject us to costly and time
consuming litigation and prevent us from developing or commercializing our products.

Our commercial success also depends in part on our ability to operate without infringing patents and proprietary rights of third parties, and without breaching
any licenses or other agreements that we have entered into with regard to our technologies, products and business. We cannot ensure that patents have not
been issued to third parties that could block our ability to obtain patents or to operate as we would like. There may be patents in some countries that, if valid,
may block our ability to make, use or sell our products in those countries, or import our products into those countries, if we are unsuccessful in circumventing
or acquiring the rights to these patents. There also may be claims in patent applications filed in some countries that, if granted and valid, may also block our
ability to commercialize products or processes in these countries if we are unable to circumvent or license them.

The industries in which we operate, and the biotechnology industry in particular, are characterized by frequent and extensive litigation regarding patents and
other intellectual property rights. Many biotechnology companies have employed intellectual property litigation as a way to gain a competitive advantage.
Our involvement in litigation, interferences, opposition proceedings or other intellectual property proceedings inside and outside of the United States, to
defend our intellectual property rights or as a result of alleged infringement of the rights of others, may divert our management's time from focusing on
business operations and could cause us to spend significant amounts of money. Any potential intellectual property litigation also could force us to do one or
more of the following:

•

•

•

•

stop selling or using our products or technologies that use the subject intellectual property;

pay monetary damages or substantial royalties;

grant cross-licenses to third parties relating to our patents or proprietary rights;

obtain from the third party asserting its intellectual property rights a license to sell or use the relevant technology, which license may not be
available on reasonable terms, or at all; or

31

Table of Contents

•

redesign those products or processes that use any allegedly infringing technology, or relocate the operations relating to the allegedly infringing
technology to another jurisdiction, which may result in significant cost or delay to us, could be technically infeasible or could prevent us from
selling some of our products in the United States or other jurisdictions.

We are aware of a significant number of patents and patent applications relating to aspects of our technologies filed by, and issued to, third parties. We cannot
assure you that if this third party intellectual property is asserted against us that we would ultimately prevail.

If any of our competitors have filed patent applications or obtained patents that claim inventions also claimed by us, we may have to participate in
interference proceedings before the United States Patent and Trademark Office to determine priority of invention and, thus, the right to the patents for these
inventions in the United States. These proceedings could result in substantial cost to us even if the outcome is favorable. Even if successful, any interference
may result in loss of certain claims. Any litigation or proceedings could divert our management's time and efforts. Even unsuccessful claims could result in
significant legal fees and other expenses, diversion of management time, and disruption in our business. Uncertainties resulting from initiation and
continuation of any patent or related litigation could harm our ability to compete.

We may not be able to enforce our intellectual property rights throughout the world.

The laws of some foreign countries, including Brazil, where we have recently begun to do business, do not protect intellectual property rights to the same
extent as the laws of the United States. Many companies have encountered significant problems in protecting and defending intellectual property rights in
certain foreign jurisdictions. The legal systems of certain countries, particularly certain developing countries, do not favor the enforcement of patents and
other intellectual property, particularly those relating to biotechnology and/or bioindustrial technologies. Accordingly, our efforts to protect our intellectual
property rights in such countries may be inadequate. This could make it difficult for us to stop the infringement of our patents or misappropriation of our other
intellectual property rights. Additionally, proceedings to enforce our patent rights in foreign jurisdictions could result in substantial costs and divert our efforts
and attention from other aspects of our business.

If our biocatalysts, or the genes that code for our biocatalysts, are stolen, misappropriated or reverse engineered, others could use these biocatalysts or
genes to produce competing products.

Third parties, including our contract manufacturers, customers and those involved in shipping our biocatalysts, often have custody or control of our
biocatalysts. If our biocatalysts, or the genes that code for our biocatalysts, were stolen, misappropriated or reverse engineered, they could be used by other
parties who may be able to reproduce these biocatalysts for their own commercial gain. If this were to occur, it would be difficult for us to challenge this type
of use, especially in countries with limited intellectual property protection or in countries in which we do not have patents covering the misappropriated
biocatalysts.

Confidentiality agreements with employees and others may not adequately prevent disclosures of trade secrets and other proprietary information.

We rely in part on trade secret protection to protect our confidential and proprietary information and processes. However, trade secrets are difficult to protect.
We have taken measures to protect our trade secrets and proprietary information, but these measures may not be effective. We require employees and
consultants to execute confidentiality agreements upon the commencement of an employment or consulting arrangement with us. These agreements generally
require that all confidential information developed by the individual or made known to the individual by us during the course of the individual's relationship
with us be kept confidential and not disclosed to third parties. These agreements also generally provide that inventions conceived by the individual in the
course of rendering services to us shall be our exclusive property. Nevertheless, our proprietary information may be disclosed, third parties could reverse
engineer our biocatalysts and others may independently develop substantially equivalent proprietary information and techniques or otherwise gain access to
our trade secrets. Costly and time-consuming litigation could be necessary to enforce and determine the scope of our proprietary rights, and failure to obtain
or maintain trade secret protection could adversely affect our competitive business position.

Competitors and potential competitors who have greater resources and experience than we do may develop products and technologies that make ours
obsolete or may use their greater resources to gain market share at our expense.

The biocatalysis industry and each of our target markets are characterized by rapid technological change. Our future success will depend on our ability to
maintain a competitive position with respect to technological advances. In addition, as we enter new markets, we will face new competition and will need to
adapt to competitive factors that may be different from what we face today.

We are aware that other companies, including Royal DSM N.V., or DSM, DuPont, Novozymes, and Vercipia Biofuels, an affiliate of BP P.L.C., have
alternative methods for obtaining and generating genetic diversity or use mutagenesis techniques to produce genetic diversity. Academic institutions such as
the California Institute of Technology, the Max Planck Institute and the Center for Fundamental and Applied Molecular Evolution (FAME), a jointly
sponsored initiative between Emory University and Georgia Institute of Technology, are also working in this field. Technological development by others may
result in our products and technologies, as well as products developed by our customers using our biocatalysts, becoming obsolete.

We face intense competition in the pharmaceuticals market. There are a number of companies who compete with us throughout the various stages of a
pharmaceutical product's lifecycle. Many large pharmaceutical companies have internal capabilities to develop and manufacture intermediates and APIs.
These companies include many of our large innovator and generic pharmaceutical customers, such as Merck, Pfizer and Teva Pharmaceutical Industries Ltd.
There are also many large, well-established fine chemical manufacturing companies, such as DSM, BASF Corporation and Lonza Group Ltd, that compete to
supply pharmaceutical intermediates and APIs to our customers. We also face increasing competition from generic pharmaceutical manufacturers and contract
manufacturers in low cost centers such as India and China.

In addition to competition from companies manufacturing APIs and intermediates, we face competition from companies that sell biocatalysts for use in the
pharmaceutical market. There is competition from large industrial enzyme companies, such as Novozymes and Amano Enzyme Inc., whose industrial
enzymes (for detergents, for example) are occasionally used in pharmaceutical processes. There is also competition in this area from several small companies
with product offerings comprised primarily of naturally occurring biocatalysts or that offer biocatalyst optimization services.

We expect to enter the market for cellulase enzymes, which are used to produce sugar for the manufacture of biofuels and bio-based chemicals. Our
significant competitors in this market include Novozymes and DuPont, which have both been active in this market for many years. Novozymes has partnered
with a number of companies and organizations on a regional basis to develop cellulases for the production of biofuels, including partnering with M&G in
Italy to be the cellulase supplier to a commercial scale cellulosic ethanol plant being built by Chemtex, and DuPont is marketing a line of cellulases to convert
cellulosic biomass into sugar. These competitors have greater resources than we do, own or otherwise control established intellectual rights portfolios, have
existing relationships with customers that we hope to sell CodeXyme® cellulase enzymes to, have long-term supply agreements already in place with
customers for their bio-based products, and have the supply chain in place to sell their cellulases on a global platform. Our ability to compete in this market
may be limited by our relatively late start. Additionally, DSM has announced that it expects to participate in this market.

There are also other companies developing competing cellulosic ethanol technologies. Significant competitors include companies such as: Novozymes, which
is opening a biofuel demonstration plant with Inbicon A/S of Denmark; DuPont is marketing a line of cellulases to convert cellulosic biomass into sugar;
DSM, which acquired C5 Yeast Company B.V. in 2011 enhancing DSM's position in the cellulosic biofuel sector, and which has recently partnered with
POET LLC to form POET-DSM Advanced Biofuels to construct a facility to produce cellulosic ethanol; Mascoma Corporation, which entered into a
definitive agreement with Valero Energy Corporation in December 2011 to build a commercial-scale cellulosic ethanol biorefinery; BP, which is developing a
commercial scale cellulosic ethanol facility through its affiliate Vercipia Biofuels; and Coskata, Inc., which is developing a hybrid thermochemical-
biocatalytic process to produce ethanol from a variety of feedstocks.

We entered the bio-based chemical market in 2011 with our CodeXol® detergent alcohols. Our significant competitors in this market include companies that
have been active in this marketplace for many years, namely Sasol, Shell, BASF, Kao Corporation and Liaoning Huaxing. These companies have greater
resources in this market than we do and have long-term supply arrangements already in place with consumer products companies. We also face competition
from smaller companies that are developing biological routes to detergent alcohols, such as LS9, Inc. Our ability to compete in this market may be limited by
our relatively late start.

Our ability to compete successfully in any of these markets will depend on our ability to develop proprietary products that reach the market in a timely
manner and are technologically superior to and/or are less expensive than other products on the market. Many of our competitors have substantially greater
production, financial, research and development, personnel and marketing resources than we do. They also started developing products earlier than we did,
which may allow them to establish blocking intellectual property positions or bring products to market before we can. In addition, certain of our competitors
may also benefit from local government subsidies and other incentives that are not available to us. As a result, our competitors may be able to develop
competing and/or superior technologies and processes, and compete more aggressively and sustain that competition over a longer period of time than we
could. Our technologies and products may be rendered obsolete or uneconomical by technological advances or entirely different approaches developed by one
or more of our competitors. We cannot be certain that any products we develop in the future will compare favorably to products offered by our competitors or
that our existing or future products will compare favorably to any new products that are developed by our competitors. As more

33

Table of Contents

companies develop new intellectual property in our markets, the possibility of a competitor acquiring patent or other rights that may limit our products or
potential products increases, which could lead to litigation.

In addition, various governments have recently announced a number of spending programs focused on the development of clean technology, including
alternatives to petroleum-based fuels. Such spending programs could lead to increased funding for our competitors or the rapid increase in the number of
competitors within those markets.

Our limited resources relative to many of our competitors may cause us to fail to anticipate or respond adequately to new developments and other competitive
pressures. This failure could reduce our competitiveness and market share, adversely affect our results of operations and financial position, and prevent us
from obtaining or maintaining profitability.

Business interruptions could delay us in the process of developing our products and could disrupt our sales.

Our headquarters is located in the San Francisco Bay Area near known earthquake fault zones and is vulnerable to significant damage from earthquakes. We
are also vulnerable to other types of natural disasters and other events that could disrupt our operations, such as riot, civil disturbances, war, terrorist acts,
flood, infections in our laboratory or production facilities or those of our contract manufacturers and other events beyond our control. We do not have a
detailed disaster recovery plan. In addition, we do not carry insurance for earthquakes and we may not carry sufficient business interruption insurance to
compensate us for losses that may occur. Any losses or damages we incur could have a material adverse effect on our cash flows and success as an overall
business.

Ethical, legal and social concerns about genetically engineered products and processes could limit or prevent the use of our products, processes, and
technologies and limit our revenues.

Some of our products and processes are genetically engineered or involve the use of genetically engineered products or genetic engineering technologies. If
we and/or our collaborators are not able to overcome the ethical, legal, and social concerns relating to genetic engineering, our products and processes may
not be accepted. Any of the risks discussed below could result in increased expenses, delays, or other impediments to our programs or the public acceptance
and commercialization of products and processes dependent on our technologies or inventions. Our ability to develop and commercialize one or more of our
technologies, products, or processes could be limited by the following factors:

•

•

•

public attitudes about the safety and environmental hazards of, and ethical concerns over, genetic research and genetically engineered products
and processes, which could influence public acceptance of our technologies, products and processes;

public attitudes regarding, and potential changes to laws governing ownership of genetic material, which could harm our intellectual property
rights with respect to our genetic material and discourage collaborators from supporting, developing, or commercializing our products, processes
and technologies; and

governmental reaction to negative publicity concerning genetically modified organisms, which could result in greater government regulation of
genetic research and derivative products. The subject of genetically modified organisms has received negative publicity, which has aroused public
debate. This adverse publicity could lead to greater regulation and trade restrictions on imports of genetically altered products. The biocatalysts
that we develop have significantly enhanced characteristics compared to those found in naturally occurring enzymes or microbes. While we
produce our biocatalysts only for use in a controlled industrial environment, the release of such biocatalysts into uncontrolled environments could
have unintended consequences. Any adverse effect resulting from such a release could have a material adverse effect on our business and
financial condition, and we may have exposure to liability for any resulting harm.

Compliance with stringent laws and regulations may be time consuming and costly, which could adversely affect the commercialization of our
bioindustrial products.

Our bioindustrial products, including those used in the biofuels and bio-based chemicals markets, will need to meet a significant number of regulations and
standards, including regulations imposed by the United States Department of Transportation, the United States Environmental Protection Agency, various
state agencies and others. In addition, our bioindustrial products will be subject to foreign regulations if we attempt to produce or sell our products outside the
United States. For example, we expect that our products and technologies will be subject to import and export controls when they are shipped internationally.
Any failure to comply or delays in compliance, with the various existing and evolving industry regulations and standards could prevent or delay the
commercialization of any bioindustrial products developed using our technologies and subject us to fines and other penalties.

34

Table of Contents

We use hazardous materials in our business and we must comply with environmental laws and regulations. Any claims relating to improper handling,
storage or disposal of these materials or noncompliance of applicable laws and regulations could be time consuming and costly and could adversely affect
our business and results of operations.

Our research and development and commercial processes involve the use of hazardous materials, including chemical, radioactive, and biological materials.
Our operations also produce hazardous waste. We cannot eliminate entirely the risk of accidental contamination or discharge and any resultant injury from
these materials. Federal, state, local and foreign laws and regulations govern the use, manufacture, storage, handling and disposal of, and human exposure to,
these materials. We may be sued for any injury or contamination that results from our use or the use by third parties of these materials, and our liability may
exceed our total assets. Although we believe that our activities comply in all material respects with environmental laws, there can be no assurance that
violations of environmental, health and safety laws will not occur in the future as a result of human error, accident, equipment failure or other causes.
Compliance with applicable environmental laws and regulations may be expensive, and the failure to comply with past, present, or future laws could result in
the imposition of fines, third party property damage, product liability and personal injury claims, investigation and remediation costs, the suspension of
production, or a cessation of operations, and our liability may exceed our total assets. Liability under environmental laws can be joint and several and without
regard to comparative fault. Environmental laws could become more stringent over time imposing greater compliance costs and increasing risks and penalties
associated with violations, which could impair our research, development or production efforts and harm our business. In addition, we may have to indemnify
some of our customers or suppliers for losses related to our failure to comply with environmental laws, which could expose us to significant liabilities.

We face compliance risks associated with our government awards.

We are subject to routine audits by government agencies or other third parties as part of our government awards. The government auditor may review our
performance, cost structures and compliance with applicable laws, regulations and standards. Funds available under government financial assistance must be
applied by us toward the research and development programs specified by the funding agencies, rather than for all of our programs generally. If any of our
costs are found to be allocated improperly, the costs may not be reimbursed and any costs already reimbursed may have to be refunded. Accordingly, an audit
could result in an adjustment to our revenues and results of operations.

We may be sued for product liability.

The design, development, manufacture and sale of our products involve an inherent risk of product liability claims and the associated adverse publicity. For
example, we may be named directly in product liability suits relating to drugs that are produced using our enzymes or that incorporate our intermediates and
APIs. The biocatalysts, pharmaceutical intermediates and APIs that we produce or are produced for us by our manufacturing partners could be subject to
quality control or contamination issues of which we are not aware. Claims could be brought by various parties, including customers who are purchasing
products directly from us, other companies who purchase products from our customers or by the end users of the drugs. We could also be named as co-parties
in product liability suits that are brought against our contract manufacturers who manufacture our enzymes, pharmaceutical intermediates and APIs, such as
Lactosan and/or Arch. Insurance coverage is expensive and may be difficult to obtain, and may not be available in the future on acceptable terms, or at all. We
cannot assure you that any contract manufacturer that we have used in the past or shall use in the future has or will have adequate insurance coverage to cover
against potential claims. In addition, although we currently maintain product liability insurance for our products in amounts we believe to be commercially
reasonable, if the coverage limits of these insurance policies are not adequate, a claim brought against us, whether covered by insurance or not, could have a
material adverse effect on our business, results of operations, financial condition and cash flows. This insurance may not provide adequate coverage against
potential losses, and if claims or losses exceed our liability insurance coverage, we may go out of business. Moreover, we have agreed to indemnify some of
our customers for certain claims that may arise out of the use of our products, which could expose us to significant liabilities.

Our ability to use our net operating loss carryforwards to offset future taxable income may be subject to certain limitations.

In general, under Section 382 of the Internal Revenue Code, a corporation that undergoes an “ownership change” is subject to limitations on its ability to
utilize its pre-change net operating loss carryforwards, or NOLs, to offset future taxable income. If the Internal Revenue Service challenges our analysis that
our existing NOLs are not subject to limitations arising from previous ownership changes, our ability to utilize NOLs could be limited by Section 382 of the
Internal Revenue Code. Future changes in our stock ownership, some of which are outside of our control, could result in an ownership change under
Section 382 of the Internal Revenue Code. Furthermore, our ability to utilize NOLs of companies that we may acquire in the future may be subject to
limitations. For these reasons, we may not be able to utilize a material portion of the NOLs reflected in our financial statements, even if we attain profitability.

Risks Related to Owning our Common Stock

We are subject to anti-takeover provisions in our certificate of incorporation and bylaws and under Delaware law, as well as our stockholder rights plan,
that could delay or prevent an acquisition of our company, even if the acquisition would be beneficial to our stockholders.

Provisions in our amended and restated certificate of incorporation and our bylaws may delay or prevent an acquisition of us. Among other things, our
amended and restated certificate of incorporation and bylaws provide for a board of directors which is divided into three classes, with staggered three-year
terms and provide that all stockholder action must be effected at a duly called meeting of the stockholders and not by a consent in writing, and further provide
that only our board of directors, the chairman of the board of directors, our chief executive officer or president may call a special meeting of the stockholders.
In addition, our amended and restated certificate of incorporation allows our board of directors, without further action by our stockholders, to issue up to
5,000,000 shares of preferred stock in one or more series and to fix the rights, preferences, privileges and restrictions thereof. These provisions may also
frustrate or prevent any attempts by our stockholders to replace or remove our current management by making it more difficult for stockholders to replace
members of our board of directors, who are responsible for appointing the members of our management team. Furthermore, because we are incorporated in
Delaware, we are governed by the provisions of Section 203 of the Delaware General Corporation Law, which prohibits, with some exceptions, stockholders
owning in excess of 15% of our outstanding voting stock from merging or combining with us. Finally, our charter documents establish advanced notice
requirements for nominations for election to our board of directors and for proposing matters that can be acted upon at stockholder meetings. Although we
believe these provisions together provide for an opportunity to receive higher bids by requiring potential acquirers to negotiate with our board of directors,
they would apply even if an offer to acquire our company may be considered beneficial by some stockholders.

On September 3, 2012, we entered into a stockholder rights plan and declared a dividend of one preferred stock purchase right for each share of our common
stock held by stockholders of record as of September 18, 2012. Each right entitles stockholders, after the rights become exercisable, to purchase one one-
thousandth of a share of our Series A Preferred Stock, par value $0.0001, at a purchase price of $11.35 per one-thousandth of a share of Series A Preferred
Stock. In general, the rights become exercisable at the close of business on the tenth business day following (i) public announcement that a person or group
acquired 15% or more of our common stock or (ii) commencement or announcement of a tender offer for 15% or more of our common stock. The rights may
discourage a third-party from making an unsolicited proposal to acquire us, as exercise of the rights would cause substantial dilution to a person or group that
attempts to acquire us on terms not approved by our board of directors. The rights should not interfere with any merger or other business combination
approved by our board of directors since the rights may be redeemed by us at $0.0001 per right at any time before any person or group acquires 15% or more
of our outstanding common stock. These rights expire in September 2013.

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

Based on the number of shares outstanding as of December 31, 2012, our officers, directors and stockholders who hold at least 5% of our stock together
beneficially own approximately 31% of our outstanding common stock. If these officers, directors, and principal stockholders or a group of our principal
stockholders act together, they will be able to exert a significant degree of influence over our management and affairs and control matters requiring
stockholder approval, including the election of directors and approval of mergers or other business combination transactions. The interests of this
concentration of ownership may not always coincide with our interests or the interests of other stockholders. For instance, officers, directors, and principal
stockholders, acting together, could cause us to enter into transactions or agreements that we would not otherwise consider. Similarly, this concentration of
ownership may have the effect of delaying or preventing a change in control of our company otherwise favored by our other stockholders. As of December
31, 2012, Raízen, Biomedical Sciences Investment Fund Pte Ltd. and CMEA Ventures beneficially owned approximately 14.8%, 8.4% and 8.0% of our
common stock, respectively.

Our share price may be volatile which may cause the value of our common stock to decline and subject us to securities class action litigation.

The market price of shares of our common stock could be subject to wide fluctuations in response to many risk factors listed in this section, and others
beyond our control, including:

•

•

•

actual or anticipated fluctuations in our financial condition and operating results;

the position of our cash, cash equivalents and marketable securities;

actual or anticipated changes in our growth rate relative to our competitors;

announcements or developments regarding technical progress of CodeXyme® cellulase enzymes or CodeXol® detergent alcohols;

additions or losses of one or more significant pharmaceutical products;

announcements or developments regarding pharmaceutical products manufactured using our biocatalysts, intermediates and APIs;

the entry into, modification or termination of collaborative arrangements;

additions or losses of customers;

additions or departures of key management or scientific personnel;

competition from existing products or new products that may emerge;

issuance of new or updated research reports by securities or industry analysts;

fluctuations in the valuation of companies perceived by investors to be comparable to us;

disputes or other developments related to proprietary rights, including patent litigation and our ability to obtain patent protection for our
technologies;

changes in existing laws, regulations and policies applicable to our business and products, including the National Renewable Fuel Standard
program;

contractual disputes or litigation with our partners, customers or suppliers;

announcement or expectation of additional financing efforts;

sales of our common stock by us, our insiders or our other stockholders;

share price and volume fluctuations attributable to inconsistent trading volume levels of our shares;

general market conditions in our industry; and

general economic and market conditions, including the recent financial crisis.

Furthermore, the stock markets have experienced extreme price and volume fluctuations that have affected and continue to affect the market prices of equity
securities of many companies. These fluctuations often have been unrelated or disproportionate to the operating performance of those companies. These broad
market and industry fluctuations, as well as general economic, political and market conditions such as recessions, interest rate changes or international
currency fluctuations, may negatively impact the market price of shares of our common stock. In the past, companies that have experienced volatility in the
market price of their stock have been subject to securities class action litigation. We may be the target of this type of litigation in the future. Securities
litigation against us could result in substantial costs and divert our management's attention from other business concerns, which could seriously harm our
business.

If securities or industry analysts do not publish research or reports about our business, or publish negative reports about our business, our stock price
and trading volume could decline.

The trading market for our common stock will be influenced by the research and reports that securities or industry analysts publish about us or our business.
We do not have any control over these analysts. If one or more of the analysts who cover us downgrade our stock or change their opinion of our stock in a
negative manner, our stock price would likely decline. If one or more of these analysts cease coverage of our company or fail to regularly publish reports on
us, we could lose visibility in the financial markets, which could cause our stock price or trading volume to decline.

37

Table of Contents

We incur significant costs as a result of operating as a public company, and our management is required to devote substantial time to compliance
initiatives.

As a public company, we incur significant legal, accounting and other expenses that we did not incur as a private company. In addition, the Sarbanes-Oxley
Act and the Dodd-Frank Wall Street Reform and Consumer Protection Act, as well as related rules implemented by the Securities and Exchange Commission
and The NASDAQ Stock Market, impose various requirements on public companies that require our management and other personnel to devote a substantial
amount of time to compliance initiatives.

In addition, the Sarbanes-Oxley Act requires, among other things, that we maintain effective internal control over financial reporting and disclosure controls
and procedures. In particular, we must perform system and process evaluation and testing of our internal control over financial reporting to allow
management and our independent registered public accounting firm to report on the effectiveness of our internal control over financial reporting, as required
by Section 404 of the Sarbanes-Oxley Act. Our compliance with Section 404 requires that we incur substantial accounting expense and expend significant
management time on compliance-related issues. Moreover, if we are not able to maintain compliance with the requirements of Section 404, our stock price
could decline, and we could face sanctions, delisting or investigations by The NASDAQ Global Market, or other material adverse effects on our business,
reputation, results of operations, financial condition or liquidity.

ITEM 1B. UNRESOLVED STAFF COMMENTS

ITEM 2. PROPERTIES

Our headquarters are located in Redwood City, California, where we lease approximately 107,000 square feet of office and laboratory space. On March 16,
2011, we entered into a Fifth Amendment to Lease (the “Fifth Amendment”) with Metropolitan Life Insurance Company (“MetLife”) with respect to our
offices located at 200 and 220 Penobscot Drive, Redwood City, California, (the “Penobscot Space”), 400 Penobscot Drive, Redwood City, California (the
“Building 2 Space”) and 640 Galveston Drive, Redwood City, California (the “Galveston Space”), and with respect to approximately 29,921 square feet of
additional space located at 101 Saginaw Drive, Redwood City, California (the “Saginaw Space”). Under the Fifth Amendment, the term of the lease of the
Penobscot Space, the Building 2 Space and the Saginaw Space lasts until January 31, 2020, and we have options to extend for two additional five year
periods. Pursuant to the Fifth Amendment, we surrendered the Galveston Space in August 2011. Due to restructuring activities undertaken during the second
half of 2012, we are in the process of vacating our Saginaw Space and marketing it for sublease.

We also lease space in the 501 Chesapeake Drive, Redwood City, California (the “501 Chesapeake Space”). In September 2012, we entered into a Sixth
Amendment to Lease (the “Sixth Amendment”) with MetLife with respect to the 501 Chesapeake Space to extend the term of the lease of the 501 Chesapeake
Space to January 31, 2017. Pursuant to the Sixth Amendment, we have two consecutive options to extend the term of the lease for the 501 Chesapeake Space
for an additional period of five years per option.

We believe that the facilities that we currently lease in California are adequate for our needs for the immediate future and that, should it be needed, additional
space can be leased to accommodate any future growth.

In Hungary, we occupy approximately 1,700 square meters (equivalent to approximately 18,000 square feet) of office and laboratory space. The term of the
lease expires in September 2016. We have an option to extend the lease for an additional term of five years. We believe that the facilities that we currently
lease in Hungary are adequate for our needs for the immediate future and that, should it be needed, additional space can be leased to accommodate any future
growth.

In Singapore, we lease approximately 1,900 square meters (equivalent to approximately 20,000 square feet) of office and laboratory space within Singapore
Science Park II. The term of the lease expires in July 2013.

As part of a restructuring plan in the third quarter of 2012, the Company committed to close its Singapore facility, which was substantially completed in
October 2012.

We are not currently a party to any material litigation or other material legal proceedings.

`ITEM 7. MANAGEMENT’S DISCUSSION AND ANALYSIS OF
FINANCIAL CONDITION AND RESULTS OF OPERATIONS

The following discussion and analysis should be read in conjunction with our audited consolidated financial statements and the related notes that appear
elsewhere in this Annual Report on Form 10-K. This Annual Report on Form 10-K contains “forward-looking statements” within the meaning of Section 21E
of the Securities Exchange Act of 1934, as amended, or the Exchange Act. These statements are often identified by the use of words such as “may,” “will,”
“expect,” “believe,” “anticipate,” “intend,” “could,” “should,” “estimate,” or “continue,” and similar expressions or variations. Such forward-looking
statements are subject to risks, uncertainties and other factors that could cause actual results and the timing of certain events to differ materially from future
results expressed or implied by such forward-looking statements. Factors that could cause or contribute to such differences include, but are not limited to,
those discussed in the section titled “Risk Factors,” set forth in Part I, Item 1A of this Annual Report on Form 10-K and elsewhere in this report. The
forward-looking statements in this Annual Report on Form 10-K represent our views as of the date of this Annual Report on Form 10-K. We anticipate that
subsequent events and developments will cause our views to change. However, while we may elect to update these forward-looking statements at some point
in the future, we have no current intention of doing so except to the extent required by applicable law. You should, therefore, not rely on these forward-looking
statements as representing our views as of any date subsequent to the date of this Annual Report on Form 10-K.

Business Overview

We engineer enzymes for pharmaceutical, biofuel and chemical production. Our proven technologies enable scale-up and implementation of biocatalytic
solutions to meet customer needs for rapid, cost-effective and sustainable process development, from research to manufacturing.

We have commercialized our technology and products in the pharmaceuticals market, which is our primary business focus. There are currently over 50
pharmaceutical firms using our technology, products and services in their manufacturing process development, including in the production of some of the
world's bestselling and fastest growing drugs.

We are developing our CodeXyme® cellulase enzymes to convert non-food plant material, which we call cellulosic biomass, into affordable sugars, which can
then be converted into renewable fuels and chemicals. We are also developing our own manufacturing process for CodeXol® detergent alcohols, which are
bio-based chemicals. Detergent alcohols are used to manufacture surfactants, which are key, active cleaning ingredients in consumer products such as
shampoos, liquid soaps and laundry detergents. We are seeking collaboration partners to assist us with the development and commercialization of CodeXyme®
cellulase enzymes and CodeXol® detergent alcohols, and we are also exploring other strategic options with respect to these products and technologies.

We create our products by applying our CodeEvolver® directed evolution technology platform, which introduces genetic mutations into microorganisms,
giving rise to changes in the enzymes that they produce. Once we identify potentially beneficial mutations, we test combinations of these mutations until we
have created variant enzymes that exhibit marketable performance characteristics superior to competitive products. This process allows us to make
continuous, efficient improvements to the performance of our enzymes.

Results of Operations Overview

To date, we have generated revenues primarily from collaborative research and development funding, pharmaceutical product sales and government awards.
Our revenues in 2012 were $88.3 million which is down significantly compared to our 2011

44

 
 
 
 
 
 
 
 
   
   
   
   
Table of Contents

revenues of $123.9 million and our 2010 revenues of $107.1 million. The decrease in revenues is primarily due to decreases in both our collaborative research
and development revenue and pharmaceutical product sales.

Most of our revenues since inception have been derived from collaborative research and development arrangements, which accounted for 57%, 58% and 66%
of our revenues in 2012, 2011 and 2010, respectively.

Our collaborative research agreement with Shell terminated effective August 31, 2012 and as a result, we no longer receive collaborative research and
development revenues from Shell subsequent to August 31, 2012. This will significantly decrease our revenues as compared to prior periods and in all future
periods. Collaborative research and development revenues received from Shell were $45.3 million, $63.2 million and $66.1 million in 2012, 2011 and 2010,
respectively, and accounted for 51%, 51% and 62% of our total revenues in 2012, 2011 and 2010, respectively.

Our product sales accounted for 41%, 40% and 31% of our revenues in 2012, 2011 and 2010, respectively. Our product sales in 2012 were $35.9 million
which is down significantly compared to our 2011 product sales of $49.0 million and only a marginal increase compared to our 2010 product revenues of
$32.8 million. The decrease in product sales as compared to 2011 is primarily due to the timing of generic and innovator pharmaceutical product orders and
due to the New Arch Enzyme Supply Agreement, which became effective on November 1, 2012, as described below.

We have experienced significant losses as we have invested heavily in research and development and administrative infrastructure in connection with the
growth in our business. We intend to continue our investment in research and development. As of December 31, 2012, we had an accumulated deficit of
$215.6 million. We incurred net losses of $30.9 million, $16.6 million and $8.5 million in the years ended December 31, 2012, 2011 and 2010, respectively.

Termination of Shell Collaboration

In September 2012, we entered into the New Shell Agreement, which terminated our collaboration with Shell under the existing Shell Research Agreement
and amended the existing Shell License Agreement. See “Collaborations and License Agreements-Shell” in Part I, Item 1 of this Annual Report on Form 10-
K for a description of the New Shell Agreement.

The New Shell Agreement required Shell to pay us $7.5 million as full, complete and final satisfaction of amounts that Shell may have owed to us under the
Shell Research Agreement with respect to (i) full-time employee equivalents, or FTEs, assigned by us to perform our obligations under the Shell Research
Agreement and (ii) milestones achieved or achievable by us under the Shell Research Agreement. We recognized this $7.5 million payment as collaborative
research and development revenues during the year ended December 31, 2012. Beginning September 1, 2012, we have no further obligations to Shell under
the Shell Research Agreement to provide any FTEs to perform work under or after the collaboration and Shell correspondingly has no future obligations to us
under the Shell Research Agreement to provide funding for FTEs to perform work under or after the collaboration.

Prior to the New Shell Agreement, Shell had an obligation under the Research Agreement to fund us at specified rates for each FTE, which as of 2012 were
equal to $460,000 on an annual basis for each FTE in the United States and $399,000 on an annual basis for each FTE in Hungary. As of August 31, 2012, the
number of FTEs assigned by us to perform our obligations under the Research Agreement was 116. For the year ended December 31, 2012, Shell accounted
for 50% of our total revenues.

As a result of the termination of the Shell Research Agreement, we initiated a series of cost reduction measures and refocused our business on the
pharmaceuticals market. We terminated approximately 173 employees worldwide, consisting of 150 research and development staff and 23 general and
administrative staff. We also closed our Singapore research and development facility. We estimate that we will incur $2.4 million in restructuring expenses
related to these cost reduction measures, including severance for terminated employees, and other exit-related costs arising from contractual obligations
associated with closed facilities under lease and equipment disposals. During 2012, we recorded $1.1 million of leasehold improvement write down, $0.7
million of employee severance and other termination benefits, $0.3 million of facility lease termination costs and $0.3 million of equipment disposal charges.
We paid $0.6 million in cash during the fourth quarter of 2012 for these restructuring expenses and expect to pay a remaining $0.4 million in the first half of
2013.

We anticipate our expected 2013 cost reductions resulting from restructuring our operation in the United States will be $22.1 million. Our total expected 2013
cost reductions resulting from closing our operations in Singapore is expected to be $7.1 million. We anticipate that these cost reduction measures will
generate annual cost savings related to employee compensation costs of $20.9 million, specifically $3.3 million in general and administrative costs and $17.6
million in research and development costs. The remaining cost reduction measure will generate annual cost savings primarily related to outside services,
information technology and laboratory equipment expenses, facilities expenses, and recruiting and relocation costs.

Despite the termination of the Shell Research Agreement, we expect to continue our advanced biofuels program, primarily focusing on developing our
CodeXyme® cellulase enzymes for use in producing advanced biofuels. We are actively seeking third party funding to support our CodeXyme® cellulase
enzyme program. We are in early stage discussions with multiple parties about potential collaborations, but there can be no assurances that any of our
discussions will lead to collaborations or that any new collaboration will fully substitute for the termination of the Shell collaboration. We are exploring other
strategic options for the program. We currently do not expect to receive development funding from Raízen, our largest shareholder, to support our
CodeXyme® cellulase enzyme program. If we are unable to agree to terms with new collaborators that provide us with the financial assistance and
infrastructure necessary for us to develop and commercialize our products and execute our strategy with respect to CodeXyme® cellulase enzymes, or if we
are unable to identify and effect attractive strategic options for that program, we will need to continue to fund this development ourselves, which will have a
material adverse effect on our liquidity and financial condition, or we may need to suspend the program, which may have a material adverse effect on our
business and prospects.

Maxygen Transaction

In October 2010, we acquired Maxygen’s directed evolution technology patent portfolio for net consideration of $20.2 million consisting of $20.0 million
paid to Maxygen, related transaction costs of $0.7 million and a royalty payable extinguishment of $0.5 million. In conjunction with this transaction, we
terminated our existing license agreement with Maxygen including terminating our obligation to pay biofuels royalties to Maxygen.

CO2 Solutions Investment

Our investment in CO2 Solutions and the joint development agreement we signed with CO2 Solutions in 2009 was our initial entry into carbon management.
We estimated the fair value of our investment in 10,000,000 common shares of CO2 Solutions using the market value of common shares as determined by
trading on the TSX Venture Exchange. During 2012, we evaluated our investment in the common shares of CO2 Solutions and determined the impairment
was other-than-temporary considering the length of time and extent to which the fair value has been less than our cost, the financial condition and near term
prospects of CO2 Solutions, and our management’s ability and intent to hold the securities until fair value recovers. As a result of our analysis, we recorded an
impairment of $0.8 million during the year ended December 31, 2012 as an expense in our consolidated statement of operations as selling, general and
administrative expense. As of December 31, 2012, the fair value of our investment in CO2 Solutions’ common stock was $0.6 million with an unrealized gain
of $47,000.

Carbon Management Program

Our carbon management program received $1.6 million in 2012 and $2.2 million in 2011 in funding under a 2010 ARPA-E Recovery Act program award
from the United States Department of Energy for development of innovative technology to remove carbon dioxide from coal-fired power plant emissions. The
award supported development of biocatalysts for more efficient carbon capture from these plants. The award agreement concluded in June 2012. We also had
a collaboration in carbon management with Alstom Power, Inc., or Alstom, which included funding for up to 12 FTEs. We recognized $3.8 million in revenue
in 2011 from this collaboration. The Alstom collaboration concluded in October 2011. We are no longer actively developing our carbon capture technology.

Singapore Economic Development Board Grant

We also received award revenues of $0.6 million in 2012 and $1.3 million in 2011 from the Singapore Economic Development Board, or EDB, for our
research and development center in Singapore. This award was terminated in December 2012 in conjunction with the closure of our Singapore research
facility.

Arch Collaboration

Since 2006, Arch of Mumbai, India has manufactured substantially all of our commercialized intermediates and APIs for sale to generic and innovator
manufacturers. We were party to a number of agreements with Arch that govern the commercialization of various current and future products for supply into
the generic and innovator marketplaces. In November 2012, we entered into the New Arch Enzyme Supply Agreement, which terminated our existing supply
agreements with Arch. Under the New Arch Enzyme Supply Agreement, Arch agreed to exclusively purchase our proprietary enzymes from us for use in the
manufacture of certain of Arch’s products and we agreed to exclusively supply, with limited exceptions, certain of our proprietary enzymes to Arch at an
agreed upon price for use in such manufacture. Arch will no longer produce API and intermediates for us to market and sell and Arch will no longer pay us
royalties on the sale of APIs and intermediates to customers. We expect that selling our proprietary enzymes to Arch rather than selling the resulting APIs or
intermediates that Arch manufactured for us will result in a decrease in our product revenues in all future periods. However, we expect that our product gross
margin will be higher, which we expect to result in a product gross profit comparable with our historical product gross profit.

Contract Manufacturers

We have limited internal manufacturing capacity at our headquarters in Redwood City, California. We expect to rely on third-party manufacturers for
commercial production of our biocatalysts for the foreseeable future. Our in-house manufacturing is dedicated to producing both our Codex® Biocatalyst
Panels and Kits and biocatalysts for use by our customers in pilot scale production. We also supply initial commercial quantities of biocatalysts for use by our
collaborators to produce pharmaceutical intermediates and manufacture biocatalysts that we sell.

We actively seek contract manufacturers who are willing to invest in capital equipment to manufacture our products at commercial scale. As a result, we are
heavily dependent on the availability of manufacturing capacity at, and the reliability of, our contract manufacturers. We also pursue collaborations with
industry leaders that allow us to leverage our collaborators’ engineering, manufacturing and commercial expertise, their distribution infrastructure and their
ability to fund commercial scale production facilities. If our collaborators choose to utilize our technology to commercialize new products, we expect our
collaborators will finance, build and operate the larger, more expensive facilities for the intermediate or end products in our markets, which will allow us to
expand into new markets without having to finance or operate large industrial facilities.

We primarily rely on one contract manufacturer Lactosan, located in Austria, to manufacture substantially all of the enzymes used in our pharmaceutical
business. We have qualified other contract manufacturers for the manufacture of our enzymes, but we do not currently use them for any of our supply
commitments. In addition, we contract with other suppliers for the manufacture of our pharmaceutical intermediates and APIs.

Other Collaborations

Our strategy for collaborative arrangements is to retain substantial participation in the future economic value of our technology while receiving current cash
payments to offset research and development costs and working capital needs. These agreements are complex and have multiple elements that cover a variety
of present and future activities. In addition, certain elements of these agreements are intrinsically difficult to separate and treat as separate units for accounting
purposes, especially exclusivity payments. Consequently, we expect to recognize these exclusivity payments over the term of the exclusivity period.

Revenues and Operating Expenses

Revenues

Our revenues are comprised of collaborative research and development revenues, product revenues and government awards.

•

•

•

Collaborative research and development revenues include license, technology access and exclusivity fees, FTE payments, milestones, royalties,
and optimization and screening fees.

Product revenues consist of sales of biocatalysts, intermediates, APIs and Codex® Biocatalyst Panels and Kits.

Government awards consist of payments from government entities. The terms of these awards generally provide us with cost reimbursement for
certain types of expenditures in return for research and development activities over a contractually defined period. Historically, we have received
government awards from Germany, Singapore and the United States.

Cost of Product Revenues

Cost of product revenues includes both internal and third-party fixed and variable costs including amortization of purchased technology, materials and
supplies, labor, facilities and other overhead costs associated with our product revenues.

Research and Development Expenses

Research and development expenses consist of costs incurred for internal projects as well as partner-funded collaborative research and development activities.
These costs include our direct and research-related overhead expenses, which include salaries and other personnel-related expenses (including stock-based
compensation), occupancy-related costs, supplies, depreciation of facilities and laboratory equipment and amortization of acquired technologies, as well as
research consultants, and are expensed as incurred. Costs to acquire technologies that are utilized in research and development and that have no alternative
future use are expensed when incurred.

Our research and development efforts devoted to our product and process development projects changed from 57 projects in 2010 to 38 projects in 2011 and
40 in 2012 as we have focused our research and development resources on fewer projects. Our internal research and development projects are typically
completed in 12 to 24 months, and generally the costs associated with any single internal project during these periods were not material.

47

Table of Contents

Selling, General and Administrative Expenses

Selling, general and administrative expenses consist of compensation expenses (including stock-based compensation), hiring and training costs, consulting
and service provider expenses (including patent counsel related costs), marketing costs, occupancy-related costs, depreciation and amortization expenses, and
travel and relocation expenses.

Critical Accounting Policies and Estimates

Management’s discussion and analysis of our financial condition and results of operations are based upon our consolidated financial statements. The
consolidated financial statements have been prepared in conformity with generally accepted accounting principles in the United States and include our
accounts and the accounts of our wholly-owned subsidiaries. The preparation of our consolidated financial statements requires our management to make
estimates, assumptions, and judgments that affect the reported amounts of assets and liabilities and disclosure of contingent assets and liabilities at the date of
the financial statements, and the reported amounts of revenues and expenses during the applicable periods. Management bases its estimates, assumptions and
judgments on historical experience and on various other factors that are believed to be reasonable under the circumstances. Different assumptions and
judgments would change the estimates used in the preparation of our consolidated financial statements, which, in turn, could change the results from those
reported. Our management evaluates its estimates, assumptions and judgments on an ongoing basis.

The critical accounting policies requiring estimates, assumptions, and judgments that we believe have the most significant impact on our consolidated
financial statements are described below.

Revenue Recognition

Revenues are recognized when the four basic revenue recognition criteria are met: (1) persuasive evidence of an arrangement exists; (2) products have been
delivered, transfer of technology has been completed or services have been rendered; (3) the fee is fixed or determinable; and (4) collectability is reasonably
assured.

Our primary sources of revenues consist of collaborative research and development agreements, product revenues and government awards. Collaborative
research and development agreements typically provide us with multiple revenue streams, including up-front fees for licensing, exclusivity and technology
access, fees for full-time employee equivalent (“FTE”) services and the potential to earn milestone payments upon achievement of contractual criteria and
royalty fees based on future product sales or cost savings by our customers. Our collaborative research and development revenues consist of revenues from
Shell, which revenues have ceased as a result of the termination of the Shell Research Agreement, and revenues from other collaborative research and
development agreements.

For each source of collaborative research and development revenues, product revenues and award revenues, we apply the following revenue recognition
criteria:

•

•

•

Up-front fees received in connection with collaborative research and development agreements, including license fees, technology access fees,
and exclusivity fees, are deferred upon receipt, are not considered a separate unit of accounting and are recognized as revenues over the relevant
performance periods.

Revenues related to FTE services recognized as research services are performed over the related performance periods for each contract. We are
required to perform research and development activities as specified in each respective agreement. The payments received are not refundable
and are based on a contractual reimbursement rate per FTE working on the project. When up-front payments are combined with FTE services in
a single unit of accounting, we recognize the up-front payments using the proportionate performance method of revenue recognition based upon
the actual amount of research and development labor hours incurred relative to the amount of the total expected labor hours to be incurred by us,
up to the amount of cash received. In cases where the planned levels of research services fluctuate substantially over the research term, we are
required to make estimates of the total hours required to perform our obligations. Research and development expenses related to FTE services
under the collaborative research and development agreements approximate the research funding over the term of the respective agreements.

A payment that is contingent upon the achievement of a substantive milestone is recognized in its entirety in the period in which the milestone is
achieved. A milestone is an event (i) that can only be achieved based in whole or in part on either our performance or on the occurrence of a
specific outcome resulting from our performance, (ii) for which there is substantive uncertainty at the date the arrangement is entered into that
the event will be achieved, and (iii) results in additional payments being due to us. Milestones are considered substantive when the consideration
earned from the achievement of the milestone (i) is commensurate with either our performance to

48

Table of Contents

achieve the milestone or the enhancement of value of the item delivered as a result of a specific outcome resulting from our performance, (ii)
relates solely to past performance, and (iii) is reasonable relative to all deliverable and payment terms in the arrangement.

Other payments received for which such payments are contingent solely upon the passage of time or the result of a collaborative partner’s
performance are recognized as revenue when earned in accordance with the contract terms and when such payments can be reasonably estimated
and collectability is reasonably assured.

We recognize revenues from royalties based on licensees’ sales of products using our technologies. Royalties are recognized as earned in
accordance with the contract terms when royalties from licensees can be reasonably estimated and collectability is reasonably assured.

We generate a significant percentage of our sales in India and other emerging markets. Customers in these countries are subject to significant
economic and other challenges that affect their cash flow, and many customers outside the United States are generally accustomed to vendor
financing in the form of extended payment terms which may exceed contractual payment terms. To remain competitive in markets outside the
United States, we may offer selected customers such payment flexibility. We consider arrangements with extended payment terms not to be
fixed or determinable, and accordingly, we defer revenue until payment is received. The costs associated with such revenue deferral are also
deferred and classified as other current assets in the financial statements.

Product revenues are recognized once passage of title and risk of loss has occurred and contractually specified acceptance criteria have been
met, provided all other revenue recognition criteria have also been met. Product revenues consist of sales of biocatalysts, intermediates, active
pharmaceutical ingredients and Codex® Biocatalyst Panels and Kits. Cost of product revenues includes both internal and third party fixed and
variable costs including amortization of purchased technology, materials and supplies, labor, facilities and other overhead costs associated with
our product revenues.

We licensed mutually agreed upon third party technology for use in our research and development collaboration with Shell. We recorded the
license payments to research and development expense, offset by the related reimbursements received from Shell. These payments made by
Shell to us are direct reimbursements of our costs. We accounted for these direct reimbursable costs as a net amount, whereby no expense or
revenue is recorded for the costs reimbursed by Shell. For any payments not reimbursed by Shell, we recognized these as expenses in the
statement of operations. We elected to present the reimbursements from Shell as a component of our research and development expense since
presenting the receipt of payment from Shell as revenues does not reflect the substance of the arrangement.

We receive payments from government entities for work performed in the form of government awards. Government awards are agreements that
generally provide us with cost reimbursement for certain types of expenditures in return for research and development activities over a
contractually defined period. Revenues from government awards are recognized in the period during which the related costs are incurred,
provided that the conditions under which the government awards were provided have been met and we have only perfunctory obligations
outstanding.

Shipping and handling costs charged to customers are recorded as revenues. Shipping costs are included in our cost of product revenues. Such
charges were not significant in any of the periods presented.

Milestone revenue

We evaluated the nature of the milestone triggering the contingent payment, and concluded that the amount can be recognized as a milestone payment based
on the facts that (i) the milestone was achieved through successful performance by us, (ii) the milestone was at risk at the inception of the arrangement, (iii)
the milestone was substantive in nature and is non-refundable, (iv) substantial effort was required by us to complete the milestone, (v) the amount of
milestone payment is reasonable in relation to the value created in achieving the milestone, and (vi) the milestone payment relates solely to past performance.
No further milestones payments are expected under this arrangement from this pharmaceutical partner.

Stock-Based Compensation

We recognize compensation expense related to share-based transactions, including the awarding of employee stock options and restricted stock units
(“RSU”), based on the estimated fair value of the awards granted.

We estimate the fair value of our stock option grants using the Black-Scholes option-pricing model. We calculate the estimated volatility rate based on
historical volatility of our common stock. Due to our limited history of grant activity, we calculate the

49

Table of Contents

expected life of options granted to employees using the “simplified method” permitted by the United States Securities Exchange Commission, or SEC, as the
average of the total contractual term of the option and its vesting period. The risk-free rate assumption was based on United States Treasury instruments
whose terms were consistent with the terms of our stock options. The expected dividend assumption was based on our history and expectation of dividend
payouts.

We account for stock options issued to non-employees based on their estimated fair value determined using the Black-Scholes option-pricing model. The fair
value of the options granted to non-employees is re-measured as they vest, and the resulting increase in value, if any, is recognized as expense during the
period the related services are rendered.

Impairment of Long-Lived Assets and Intangible Assets

Long-lived and intangible assets with finite lives are reviewed for impairment whenever events or changes in circumstances indicate the carrying amount of
an asset may not be recoverable. Recoverability of these assets is measured by comparison of their carrying amounts to future undiscounted cash flows the
assets are expected to generate.

The Company's intangible assets with finite lives consist of customer relationships, developed core technology, trade names, and the intellectual property
(“IP”) rights associated with the acquisition of Maxygen's directed evolution technology in 2010. Intangible assets were recorded at their fair values at the
date we acquired the assets and, for those assets having finite useful lives, are amortized using the straight-line method over their estimated useful lives. The
Company's long-lived assets include property, plant and equipment, and other non-current assets.

We determined that we have a single entity wide asset group (“Asset Group”). The directed evolution technology patent portfolio acquired from Maxygen
(“Core IP”) is the most significant component of the Asset Group since it is the base technology for all aspects of our research and development, and
represents the basis for all of our identifiable cash flow generating capacity. Consequently, we do not believe that identification of independent cash flows
associated with our long-lived assets is currently possible at any lower level than the Asset Group.

The Core IP is the only finite-lived intangible asset on our balance sheet as of December 31, 2012 and is considered the primary asset within the Asset Group.
The remaining useful life of the Core IP extends through the fourth quarter of 2016. There has been no significant change in the utilization or estimated life of
our Core IP since we acquired the technology patent portfolio from Maxygen. The estimated remaining useful life of our Core IP is not impacted by the
termination of the Shell Research Agreement.

The carrying value of our long-lived assets in the Asset Group may not be recoverable based upon the existence of one or more indicators of impairment
which could include: a significant decrease in the market price of the Company's common stock; current period cash flow losses or operating losses combined
with a history of losses or a forecast of continuing losses associated with the use of the assets; slower growth rates in our industry; significant adverse changes
in the business climate or legal factors; accumulation of costs significantly in excess of the amount originally expected for the acquisition or construction of
the assets; loss of significant customers or partners; or the current expectation that the assets will more likely than not be sold or disposed of significantly
before the end of their estimated useful life.

We evaluate recoverability of our long-lived assets and intangible assets based on the sum of the undiscounted cash flows expected to result from the use, and
the eventual disposal of, the Asset Group. We make estimates and judgments about the future undiscounted cash flows over the remaining useful life of the
Asset Group. Our anticipated future cash flows include our estimates of existing or in process product revenues, production and operating costs, future capital
expenditures, working capital needs, and assumptions regarding the ultimate sale of the Asset Group at the end of the life of the primary asset. The useful life
of the Asset Group was based on the remaining useful life of the Core IP, the primary asset.

As of December 31, 2012 we determined that our continued operating losses and the termination of the Shell Research Agreement were indications of
impairment. Consequently, we tested our long-lived assets and intangible assets for impairment as of December 31, 2012.

As part of a comprehensive strategic planning exercise the Company undertook in the fourth quarter of 2012 and early 2013, we developed a detailed multi-
year operating plan of both revenue and expense. Our best-estimate of future cash flows used to test the recoverability of the Asset Group as of December 31,
2012 was developed directly from this plan using a forecast period consistent with the remaining useful life of the Core IP. Although our cash flow forecasts
are based on assumptions that are consistent with our plans, there is significant exercise of judgment involved in determining the cash flows attributable to our
Asset Group over its estimated remaining useful life.

The undiscounted cash flows included revenue and expense from our core pharmaceutical business and other enzyme markets adjacent to our pharmaceutical
business. These adjacent enzyme businesses, which will leverage our Core IP and

50

Table of Contents

pharmaceutical technology and processes, include business opportunities in the fine chemical and enzymatic therapeutic markets.

We typically receive revenues from our core pharmaceutical business and expect to receive revenues from other enzyme markets adjacent to our
pharmaceutical business in the form of one or more of the following: up-front payments, milestone payments, payments based upon the number of full-time
employee equivalents, or FTEs, engaged in related research and development activities and licensing fees and royalties. Our best estimate of future cash flows
does not include any CodeXol® and CodeXyme® revenues associated with collaboration research and development agreements, but does include an estimate
of cash flows from potential strategic transactions with respect to our CodeXyme® and CodeXol® programs, as described below.

Approximately 69% and 31% of total Company revenues included in our estimated undiscounted cash flows (excluding cash flows from potential strategic
transactions with respect to our CodeXyme® and CodeXol® programs) over the remaining useful life of the Core IP are derived from our core pharmaceutical
business and adjacent enzyme opportunities, respectively.

Our core pharmaceutical business revenues are estimated based on existing commercial relationships, signed agreements or contracts, and conservative
estimates for the capture of additional market share that management determined to be reasonably achievable. For existing and in process customer revenues
we assumed a modest rate of growth based on our historical business model for our core pharmaceutical business, including research and development
services revenue from partners and customers, which management determined to be reasonably achievable. We have historically worked closely with our
pharmaceutical partners, such as Merck, to evolve, engineer and develop enzymes that meet their specific needs. Our business model is based on having our
partners and customers pay in whole or in part for the research and development required to engineer the enzymes required.

In determining which adjacent enzyme markets to exploit, management assessed various segments of the large and growing enzyme markets and selected
those adjacent markets where we already had entry points through our existing pharmaceutical business relationships, such as fine chemicals and enzymatic
therapeutics markets. Estimated revenues associated with these adjacent markets are based on market penetration and adoption rates that management
determined to be reasonably achievable.

We calculated our expected residual value in 2016 by applying a Gordon Growth Model to our estimated 2016 normalized net cash flows using a discount
rate of 18% (“Estimated Weighted-Average Cost of Capital”), long term growth rate of 2%, and a capitalization factor of 6.25. The 18% discount rate reflects
the nature and the risk of the underlying forecast, and includes such financial components as the risk free rate, systemic stock price risk based on an
evaluation with peer companies (“beta”), equity risk premium, size premium, and company specific risk. The long term growth rate of 2% reflects projected
inflation and general economic conditions. Based on these estimates, judgments, and factors, we determined that the residual value included in the
undiscounted cash flows was $72.3 million.

We also included in the undiscounted cash flows an estimate of cash flows from potential strategic transactions with respect to our existing CodeXyme®
cellulase enzymes and CodeXol® detergent alcohols programs. The amount of estimated cash flows was determined by probability weighting different
scenarios to derive at a weighted average of most probable outcomes, with CodeXol® and CodeXyme® representing 11% and 27%, respectively, of the total
undiscounted cash flows associated with the Asset Group. These amounts are not based on any existing signed contracts or agreements.

The result of our fourth quarter 2012 impairment analysis indicates that the undiscounted cash flows for the Asset Group are greater than the carrying value of
the Asset Group by approximately 14%.

Any inability to align future production costs, operating costs, capital expenditures and working capital needs with significant changes in the timing and/or
level of estimated future revenue could adversely impact our projected undiscounted cash flows. Future changes in the estimated useful life of our long-lived
assets could also adversely impact our projected undiscounted cash flows and result in future impairment charges. If it is determined that the Asset Group is
not recoverable, an impairment loss would be calculated based on the excess of the carrying amount of the intangible and long-lived assets over the fair value.
Any future impairment charges could have a material adverse effect on our financial position and results of operations.

Impairment of Goodwill

Goodwill represents the excess of the purchase price over the fair value of assets acquired and liabilities assumed. Goodwill is presumed to have an indefinite
life and is not subject to amortization. Goodwill is reviewed for impairment annually and whenever events or changes in circumstances indicate that the
carrying value of the goodwill may not be recoverable.

We determined that the Company has only one operating segment and reporting unit under the criteria in ASC 280, Segment Reporting, and accordingly, all of
our goodwill is associated with the Company. Our review of goodwill for indicators of impairment is performed at the Company level.

51

Table of Contents

The goodwill impairment test consists of a two-step process. The first step of the goodwill impairment test, used to identify potential impairment, compares
the fair value of the reporting unit to its carrying value. If the fair value of the reporting unit exceeds its carrying amount, goodwill of the reporting unit is
considered not impaired, and the second step of the impairment test is not required.

We use our market capitalization as an indicator of fair value. We believe that since our reporting unit is publicly traded, the ability of a controlling
shareholder to benefit from synergies and other intangible assets that arise from control might cause the fair value of our reporting unit as a whole to exceed
its market capitalization. However, we believe that the fair value measurement need not be based solely on the quoted market price of an individual share of
our common stock, but also can consider the impact of a control premium in measuring the fair value of our reporting unit.

Should our market capitalization be less than our total stockholder's equity as of our annual test date or as of any interim impairment testing date, we would
also consider market comparables, recent trends in our stock price over a reasonable period and, if appropriate, use an income approach (discounted cash
flow) to determine whether the fair value of our reporting unit is greater than our carrying amount.

If we were to use an income approach we would establish a fair value by estimating the present value of our projected future cash flows expected to be
generated from our business. The discount rate applied to the projected future cash flows to arrive at the present value would be intended to reflect all risks of
ownership and the associated risks of realizing the stream of projected future cash flows. Our discounted cash flow methodology would consider projections
of financial performance for a period of several years combined with an estimated residual value. The most significant assumptions we would use in a
discounted cash flow methodology are the discount rate, the residual value and expected future revenues, gross margins and operating costs, along with
considering any implied control premium.

The second step, if required, compares the implied fair value of the reporting unit goodwill with the carrying amount of that goodwill. If the carrying amount
of the reporting unit's goodwill exceeds its implied fair value, an impairment charge is recognized in an amount equal to that excess. Implied fair value is the
excess of the fair value of the reporting unit over the fair value of all identified assets and liabilities.

Goodwill was tested for impairment as of October 1, 2012, the date of the Company's annual impairment review. The Company concluded that the fair value
of the reporting unit exceeded the carrying value and no impairment existed. No impairment charges were recorded during the years ended December 31,
2012, 2011 and 2010.

Income Tax Provision

We use the liability method of accounting for income taxes, whereby deferred tax assets or liability account balances are calculated at the balance sheet date
using current tax laws and rates in effect for the year in which the differences are expected to affect taxable income. Valuation allowances are provided when
necessary to reduce deferred tax assets to the amount that will more likely than not be realized.

We make certain estimates and judgments in determining income tax expense for financial statement purposes. These estimates and judgments occur in the
calculation of tax credits, benefits and deductions and in the calculation of certain tax assets and liabilities, which arise from differences in the timing of
recognition of revenues and expenses for tax and financial statement purposes. Significant changes to these estimates may result in an increase or decrease to
our tax provision in a subsequent period.

In assessing the realizability of deferred tax assets, we consider whether it is more likely than not that some portion or all of the deferred tax assets will be
realized on a jurisdiction by jurisdiction basis. The ultimate realization of deferred tax assets is dependent upon the generation of taxable income in the future.
We have recorded a deferred tax asset in jurisdictions where ultimate realization of deferred tax assets is more likely than not to occur.

We make estimates and judgments about our future taxable income that are based on assumptions that are consistent with our plans and estimates. Should the
actual amounts differ from our estimates, the amount of our valuation allowance could be materially impacted. Any adjustment to the deferred tax asset
valuation allowance would be recorded in the income statement for the periods in which the adjustment is determined to be required.

We account for uncertainty in income taxes as required by the provisions of ASC Topic 740, Income Taxes, which clarifies the accounting for uncertainty in
income taxes recognized in an enterprise’s financial statements. The first step is to evaluate the tax position for recognition by determining if the weight of
available evidence indicates that it is more likely than not that the position will be sustained on audit, including resolution of related appeals or litigation
processes, if any. The second step is to estimate and measure the tax benefit as the largest amount that is more than 50% likely of being realized upon ultimate

52

settlement. It is inherently difficult and subjective to estimate such amounts, as this requires us to determine the probability of various possible outcomes. We
consider many factors when evaluating and estimating our tax positions and tax benefits, which may require periodic adjustments and may not accurately
anticipate actual outcomes.

The Tax Reform Act of 1986 and similar state provisions limit the use of net operating loss carryforwards in certain situations where equity transactions result
in a change of ownership as defined by Internal Revenue Code Section 382. In the event we should experience an ownership change, as defined, utilization of
our federal and state net operating loss carryforwards could be limited.

Revenues decreased during the year ended December 31, 2012 compared to the year ended December 31, 2011, due to decreases across all sources of
revenues, including product sales, collaborative research and development arrangements and government awards.

Product revenues decreased $13.1 million or 27% in 2012 compared to 2011 due to a decrease in product sales to both generic and innovator pharmaceutical
customers. Product revenues from our statin-family of products decreased by $9.1 million in 2012 compared to 2011. Our 2011 sales of statin-family of
products benefited from generics manufacturers stocking inventory in anticipation of the Lipitor patent expiration in 2012. Our 2012 sales of statin-family of
products were negatively impacted subsequent to the Lipitor patent expiration as the industry consumed its inventory and delayed additional orders of our
statin-

family of products. Due to the New Arch Enzyme Supply Agreement, as described above, which became effective on November 1, 2012, we expect the
resulting decrease in sales of statin-family of products will result in a decrease in our product revenues in all future periods.

Additionally, product revenues from our products used in on-patent pharmaceuticals decreased during 2012 compared to 2011 by $4.8 million, specifically
$1.9 million for products used in hepatitis C therapies, $1.6 million for products used in cancer therapies, and $1.3 million for products used in diabetic
therapies. The decrease is primarily due to the delay of product orders of our products used in hepatitis C and diabetic therapies from late 2012 to early 2013.
Further, the decrease in 2012 for products used in cancer therapies is primarily due to the accelerated manufacturing process development and drug
qualification by an innovator pharmaceutical manufacturer in 2011. We expect that our product revenues from products used in cancer therapies in 2013 will
remain comparable with 2012.

Collaborative research and development revenues were $50.1 million for 2012 and consisted of $45.3 million in revenues under the Shell Research
Agreement and $4.8 million for collaborative research and development revenues from pharmaceutical customers.

Our collaborative research agreement with Shell terminated effective August 31, 2012 and as a result, our collaborative research and development revenues
derived from Shell decreased $17.9 million to $45.3 million in 2012 compared to $63.2 million in 2011. This decrease is also a result of no Shell milestone
payments earned during 2012 while $5.6 million were earned during 2011. We had an average of 116 FTEs in this collaboration until the termination on
August 31, 2012. During 2011, we had an average of 124 FTEs in this collaboration.

Our other collaborative research and development revenues decreased $3.4 million due to $3.9 million decrease in our revenues from collaborations with
Alstom in carbon management which was partially offset by $0.5 million increase in our pharmaceutical collaboration projects in 2012. Our research
agreements with customers researching carbon capture technologies were concluded in December 2011. Our award from the United States Department of
Energy expired in June 2012. We are no longer actively developing our carbon capture technology and do not expect any revenues from our carbon
management program.

Government award revenues decreased $1.2 million during 2012 compared to 2011 as our award from the United States Department of Energy, or DOE,
under the ARPA-E Recovery Act program concluded June 30, 2012, and our award from the EDB was terminated as a result of closing our Singapore facility.
Our award revenue from the DOE was $1.6 million in 2012 compared to $2.2 million 2011. Our award from the EDB was $0.6 million during 2012 compared
to $1.3 million in 2011. As of December 31, 2012, we do not have any government awards from which we expect to receive revenues in future periods. We
may bid on additional awards from the United States and other governments in the future, but we cannot be certain that we will receive any such awards.

Our top five customers accounted for 83% and 77% of our total revenues in 2012 and 2011, respectively. Shell accounted for 51% and 51% of our total
revenues in 2012 and 2011, respectively.

Our cost of product revenues decreased $11.1 million in 2012 compared to 2011 primarily due to the $13.1 million decrease in our product sales. The
decrease in product sales was primarily due to $9.1 million decrease in sales of our statin-family of products to generics manufacturers, which generally
produce lower gross margins. Additionally, our products used in on-patent pharmaceuticals in hepatitis C therapies, in cancer therapies, and in diabetic
therapies, which generally produce greater gross margins, had a combined decrease in product sales of $4.8 million. As a result, our gross margin in 2012 was
15%, the same as for 2011.

Our inventory balance decreased $3.2 million, or 71%, from $4.5 million as of December 31, 2011 to $1.3 million as of December 31, 2012 as a result of
reduction of our enzyme inventory held at Arch by $1.8 million in preparation of the

simplified enzyme sale arrangement that we entered into with Arch in November 2012. In-transit shipments as of December 31, 2011 accounted for $0.7
million of the reduction while there were no in-transit shipments as of December 31, 2012. Additionally, we wrote-off an additional $0.4 million of our
inventory due to the continuous aging of inventory.

Research and Development. Research and development expenses decreased $4.3 million in 2012 compared to 2011 primarily due to a $2.2 million
decrease in compensation expenses (including $1.0 million decrease in stock-based compensation) as we significantly decreased headcount in the second half
of 2012. Lab supplies decreased $1.3 million as a result of the termination of research efforts in the Shell Research Agreement in the second half of 2012 and
our reduced headcount from the reduction in force announced in the third quarter of 2012. We reduced our travel costs $0.9 million and our outside services
by $0.5 million as a result of the cost reduction measures and the termination of research efforts in the Shell Research Agreement. This was offset by an
increase in depreciation costs of $0.9 million as a result of an expansion of lab space that we completed in early 2012. Research and development expenses
included stock-based compensation expense of $2.3 million and $3.3 million during 2012 and 2011, respectively. The stock-based compensation expense
decrease is attributable to canceled options resulting from the headcount reduction during 2012 and fewer outstanding options compared to 2011.

Selling, General and Administrative. Selling, general and administrative expenses decreased $5.6 million in 2012 compared to 2011 primarily due to a

$4.6 million decrease in compensation expenses (including $3.4 million decrease in stock-based compensation) as we significantly decreased headcount in the
second half of 2012. Outside services decreased $1.7 million related to decreased consulting costs of $0.9 million, decreased legal costs of $0.5 million and
decreased accounting costs of $0.3 million. Our travel costs decreased $0.8 million due to decreased international travel. Selling, general and administrative
expenses included stock-based compensation expense of $2.7 million and $6.1 million during 2012 and 2011, respectively. The stock-based compensation
expense decrease is attributable to canceled options resulting from the headcount reduction during 2012 and fewer outstanding options compared to 2011.

During the third quarter of 2012, our board of directors approved and committed to a restructuring plan (the “Q3 2012 Restructuring Plan”) to reduce our cost
structure which included approximately 173 employee terminations in the United States and Singapore and the closing of our Singapore facility.
Approximately 150 of the total 173 employee terminations impacted the research and development functions with remaining 23 employees impacting the
general and administrative functions. We anticipate these terminations will reduce our 2013 personnel cost in the United States by $16.9 million. We are in
the process of vacating one of our Redwood City facilities and marketing it for sublease. We anticipate our expected 2013 cost reductions resulting from
restructuring our operation in the United States will be $22.1 million, but the actual amount of cost reductions will depend on a number of factors, including
our ability to obtain a sublessee for the vacated facility we seek to sublease and our ability to reduce other non-personnel-related costs. Our total 2013 cost
reductions resulting from closing our operations in Singapore is expected to be $7.1 million.

Our cost of the Q3 2012 Restructuring Plan was $2.4 million, comprised of $1.1 million of leasehold improvement write down, $0.7 million for employee
severance and other termination benefits, $0.3 million for facility lease termination costs and $0.3 million for equipment disposal charges. As of December
31, 2012, planned costs of $1.5 million have been recognized in

During the first quarter of 2012, our board of directors approved and committed to a restructuring plan (the “Q1 2012 Restructuring Plan”) to reduce our cost
structure, which included a total of 13 employee terminations in Hungary, Singapore, and the United States. The total planned cost of the Q1 2012
Restructuring Plan was $567,000, comprised of employee severance and other termination benefits. As of December 31, 2012, actual costs of $572,000 have
been recognized in selling, general and administrative expenses on our consolidated statements of operations. We have made cash payments of $512,000 and
recorded $60,000 of reductions to previously recorded charges and have no further obligations under this restructuring plan. We do not anticipate recording
any further charges under this restructuring plan.

Revenues increased during the year ended December 31, 2011 compared to the year ended December 31, 2010, due to increases from product sales and
collaborative research and development projects which were partially offset by a decline from government awards.

Product revenues increased $16.2 million or 49% in 2011 compared to 2010 primarily due to an increase in product sales to both generic and innovator
pharmaceutical customers. Product revenues from our statin-family of products increased $10.1 million in 2011 compared to 2010. Our 2011 sales of statin-
family of products benefited from generics manufacturers stocking inventory in anticipation of the Lipitor patent expiration in 2012. Additionally, product
revenues from our products used in on-patent pharmaceuticals increased $6.8 million in 2011 compared to 2010 primarily due to $4.3 million increase in sales
of products used in hepatitis C therapies, $1.7 million for products used in cancer therapies, and $0.8 million for products used in dementia therapies. The
increases were partially offset by $0.9 million decrease in sales of products used in diabetic therapies.

Collaborative research and development revenues increased $1.2 million in 2011 compared to 2010 primarily due to $3.9 million increase in our revenues
from collaborations with Alstom in carbon management partially offset by a $2.9 million decrease in our collaboration revenues related to Shell. Our
pharmaceutical collaboration projects increased $0.3 million in 2011.

Collaborative research and development revenues derived from Shell decreased $2.9 million to $63.2 million in 2011 compared to $66.1 million in 2010. This
includes milestone payments of $5.6 million and $7.4 million earned during 2011 and 2010, respectively. We achieved four of six milestone targets in 2011
and seven of eight milestone targets in 2010. Effective August 2011, Shell reduced the number of funded FTEs engaged in our research and development
collaboration with them from 128 to 116 FTEs. This reduction was to FTEs located in the United States. We had an average of 124 and 128 FTEs in this
collaboration during the years ended December 31, 2011 and 2010, respectively. The decrease in the number of Shell funded FTEs in our collaborative
research and development revenues during the year ended December 31, 2011 was partially offset by contractual increases in the billing rates for those FTEs.

Government awards revenues decreased $0.6 million in 2011 due to the recognition of an award from the EDB for $1.3 million in 2011 compared to $3.2
million in 2010. This decrease was partially offset by an increased award from the United States Department of Energy of $2.2 million in 2011, compared to
$0.9 million in 2010.

Our top five customers accounted for 77% and 85% of our total revenues in 2011 and 2010, respectively. Shell accounted for 51% and 62% of our total
revenues in 2011 and 2010, respectively.

Cost of product revenues increased $13.8 million in 2011 compared to 2010 primarily due to an increase in product sales of $16.2 million. The increase in
product sales was primarily due to $10.1 million increase in sales of our statin-family of products to generics manufacturers, which generally produce lower
gross margins. Additionally, our products used in on-patent

pharmaceuticals in hepatitis C therapies, in cancer therapies, in diabetic therapies, and in dementia therapies, which generally produce greater gross margins,
had a net increase of $5.9 million. As a result, gross margins in 2011 were flat at 15% for 2011 and 2010.

Our inventory balance increased $1.7 million, or 59%, from $2.8 million as of December 31, 2010 to $4.5 million as of December 31, 2011 primarily due to
$0.7 million of in-transit shipments and $0.9 million of our enzyme inventory held at Arch as of December 31, 2011.

Research and Development. Research and development expenses increased $8.6 million in 2011 compared to 2010 primarily due to a $2.8 million

increase in amortization related to our October 2010 acquisition of the Maxygen IP. Our royalty fees paid to Maxygen were zero in 2011 compared to $1.2
million in 2010. The decrease is a result of our acquisition of the Maxygen IP and therefore we are no longer obliged to pay royalties to Maxygen.
Additionally, compensation expenses (including stock-based compensation) increased $2.2 million due to increases in headcount. We increased costs
approximately $1.0 million for additional product development batches for our research and development efforts. Outside services increased $1.0 million in
connection with development cost for our contract manufacturers and lab space expansions. Lab supplies increased $0.9 million to support our increased
headcount and ongoing development work. Our facility costs increased $0.8 million primarily as a result of costs to expand our space in Redwood City,
California. Costs of information technology equipment and services increased $0.7 million in support of the additional headcount and expanded capabilities.
Our travel costs increased $0.5 million primarily related to increased international travel. Research and development expenses include stock-based
compensation expense of $3.3 million and $3.4 million during 2011 and 2010, respectively.

Selling, General and Administrative. Selling, general and administrative expenses increased $3.1 million in 2011 compared to 2010 primarily due to a

$1.4 million increase in compensation expenses (including stock-based compensation) as we increased headcount. Outside services increased $0.7 million
related to increased consulting costs. Recruiting and relocation costs increased $0.6 million in support our increased headcount. Our travel costs increased
$0.5 million due to increased international travel. Selling, general and administrative expenses included stock-based compensation expense of $6.1 million
and $5.4 million during 2011 and 2010, respectively. The stock-based compensation expense increase is attributable to additional options granted and
outstanding during 2011 compared to 2010.

Interest Income. Interest income increased $0.1 million due to higher average interest rates received on our cash, cash equivalents and marketable

securities balances during 2011 compared to 2010.

Interest Expense and Other, Net. Interest expense and other, net, decreased $0.5 million during 2011 compared to 2010 due to $0.7 million expense

from the fair value adjustment related to our preferred stock warrants in 2010 that did not reoccur in 2011 and a decrease in interest expense of $0.5 million
due to the payoff of our debt obligation on the GE Capital Loan also in 2010. These were offset by an increase of $0.4 million in unrealized foreign exchange
losses primarily related to our operations in Hungary and $0.4 million of other income derived in 2010 from contractual arrangements with Arch that did not
reoccur in 2011.

We have historically experienced negative cash flow from operations as we continue to invest in our infrastructure, our technology platform, and expand our
business. Our cash flows from operations will continue to be affected principally by our headcount, primarily in research and development. The timing of
hiring of skilled research and development personnel affects cash flows in particular as there is a lag between the hiring of research and development
personnel and the generation of collaboration or product revenues and cash flows from those personnel. Our primary source of cash flows from operating
activities is cash receipts from our customers for purchases of products from us or research and development services. Our largest uses of cash from operating
activities are for employee-related expenditures, rent payments, inventory purchases to support our product revenue and non-payroll research and
development costs. We currently intend to continue our investment in research and development.

The Shell Research Agreement terminated effective as of August 31, 2012, and we do not expect to receive further collaboration revenues from Shell. We
have derived a substantial portion of our revenues from the Shell Research Agreement. Collaborative research and development revenues received from Shell
were $45.3 million, $63.2 million and $66.1 million in 2012, 2011 and 2010, respectively, and accounted for 51%, 51% and 62% of our total revenues in
2012, 2011 and 2010, respectively. We are in early-stage discussions with multiple parties about potential collaborations but we cannot assure you that any of
our discussions will lead to collaborations or that any new collaboration will fully substitute for the termination of the Shell collaboration. We currently do not
expect to receive development funding from Raízen to support our CodeXyme® cellulase enzyme program. We are also exploring other strategic options for
our CodeXyme® cellulase enzyme program. If we are unable to agree to terms with new collaborators that provide us with the financial assistance and
infrastructure necessary for us to develop and commercialize our products and execute our strategy with respect to CodeXyme® cellulase enzymes, or if we
are unable to identify and effect attractive strategic options for that program, we may need to fund this development ourselves, which will have a material
adverse effect on our liquidity and financial condition, or we may need to suspend the program, which may have a material adverse effect on our business and
prospects.

As a result of the expected significant decrease in revenues following the termination of the Shell Research Agreement, we implemented a significant
restructuring plan in the third quarter of 2012. This restructuring plan, when completed in early 2013, will result in the closure of our research facility in
Singapore, the closure of a facility in Redwood City and the termination of approximately 173 of our more than 332 employees worldwide. As a result of
these cost reductions, we anticipate total operating cost reduction of $29.2 million for the year ended December 31, 2013.

Although we believe that, based on our current level of operations, our existing cash, cash equivalents and marketable securities will provide adequate funds
for ongoing operations, planned capital expenditures and working capital requirements for at least the next 12 months, we may need additional capital if our
current plans and assumptions change. Our need for additional capital will depend on many factors, including the financial success of our pharmaceutical
business, identifying business partners to fund our cellulase program and our CodeXol® detergent alcohol program, or identifying other strategic options with
respect to such programs, our spending to develop and commercialize new and existing products, the effect of any acquisitions of other businesses,
technologies or facilities that we may make or develop in the future, our spending on new market opportunities, including bio-based chemicals, and the filing,
prosecution, enforcement and defense of patent claims. If our capital resources are insufficient to meet our capital requirements, and we are unable to enter
into or maintain collaborations with partners that are able or willing to fund our development efforts or commercialize any products that we develop or
enable, we will have to raise additional funds to continue the development of our technology and products and complete the commercialization of products, if
any, resulting from our technologies. If future financings involve the issuance of

59

 
 
Table of Contents

equity securities, our existing stockholders would suffer dilution. If we raise debt financing, we may be subject to restrictive covenants that limit our ability to
conduct our business. We may not be able to raise sufficient additional funds on terms that are favorable to us, if at all. If we fail to raise sufficient funds and
fail to generate sufficient revenues to achieve planned gross margins and to control operating costs, our ability to fund our operations, take advantage of
strategic opportunities, develop products or technologies, or otherwise respond to competitive pressures could be significantly limited. If this happens, we
may be forced to delay or terminate research or development programs or the commercialization of products resulting from our technologies, curtail or cease
operations or obtain funds through collaborative and licensing arrangements that may require us to relinquish commercial rights, or grant licenses on terms
that are not favorable to us. If adequate funds are not available, we will not be able to successfully execute our business plan or continue our business.

Our operating activities in 2012 used cash of $11.9 million, primarily due to our net loss of $30.9 million in 2012, decreases in our accounts payable of $6.7
million resulting from the timing of our vendor payments and decreases in our accrued expenses of $3.3 million primarily from lower employee-accrued
compensation, and increases in prepaid expenses and other current assets of $3.1 million primarily due to advances to our contract manufacturer. These were
partially offset by decreases in accounts receivable of $11.4 million primarily due to decreased product revenues and decreases in product inventory of $3.2
million primarily due to the New Arch Enzyme Supply Agreement entered into with Arch in the fourth quarter of 2012. We also had net non-cash charges of
$20.4 million, comprised primarily of non-cash share-based compensation expense of $5.1 million, $8.9 million in depreciation and amortization of property
and equipment and $3.5 million in amortization of intangible assets. Additionally, we had non-cash charges of $0.8 million related to an other-than-temporary
impairment of our equity investment in CO2 Solutions and $1.6 million in non-cash charges related to the disposal of property and equipment resulting from
our restructuring efforts during 2012.

Our operating activities in 2011 used cash of $0.5 million, primarily due to our net loss of $16.6 million in 2011, and increases in accounts receivable of $3.6
million due to increased product revenues and the timing of payments from Shell and a decrease in deferred revenues of $4.3 million primarily as a result of
billings to Shell recognized to revenue during 2011. We also had net non-cash charges of $21.6 million, comprised primarily of non-cash share-based
compensation expense of $9.4 million, $7.8 million in depreciation and amortization of property and equipment and $3.7 million in amortization of intangible
assets.

Our operating activities in 2010 used cash of $16.4 million, primarily due to our net loss of $8.5 million in 2010, and increases in accounts receivable of $8.1
million due to increased product revenues and the timing of payments from Shell and a decrease in deferred revenues of $15.1 million primarily as a result of
2009 billings to Shell recognized to revenue during 2010. We also had net non-cash charges of $19.0 million, comprised primarily of non-cash share-based
compensation expense of $8.7 million, $7.2 million in depreciation and amortization of property and equipment and $1.1 million in amortization of intangible
assets.

Cash Flows from Investing Activities

In 2012, cash provided by investing activities totaled $16.7 million and primarily consisted of a net decrease in marketable securities of $19.6 million, offset
by capital expenditures of $2.9 million primarily related to improvements for our facility expansion and purchase of lab equipment.

In 2011, cash used in investing activities totaled $48.8 million and primarily consisted of a net increase in marketable securities of $38.0 million and capital
expenditures of $10.7 million primarily related to improvements for our facility expansion and purchase of development and lab equipment.

In 2010, cash used in investing activities totaled $5.2 million and primarily consisted of capital expenditures of $7.0 million primarily related to leasehold
improvements for lab space expansion and purchase of manufacturing and lab equipment and $20.7 million for the acquisition of the Maxygen IP, funded by a
net decrease in marketable securities of $23.2 million.

Accounting Guidance Update

Recently Adopted Accounting Guidance

In September 2011, the FASB issued ASU 2011-08 that simplifies goodwill impairment tests. The new guidance states that a “qualitative” assessment may be
performed to determine whether further impairment testing is necessary. We adopted this accounting standard January 1, 2012, and the adoption of this
guidance did not have a material impact to our financial statements or disclosures.

In June 2011, the FASB issued ASU 2011-05 that eliminates the option to present items of other comprehensive income (“OCI”) as part of the statement of
changes in stockholders’ equity, and instead requires either, OCI presentation and net income in a single continuous statement in the statement of operations,
or as a separate statement of comprehensive income. This new guidance is effective for fiscal years, and interim periods within those years, beginning after
December 15, 2011, with early adoption permitted. The Company adopted this update in the fourth quarter of 2012. The adoption of this accounting guidance
did not have a material impact on our financial statements.

In May 2011, the FASB issued ASU 2011-04 that clarifies and changes some fair value measurement principles and disclosure requirements. Among them is
the clarification that the concepts of highest and best use and valuation premise in a fair value measurement, should only be applied when measuring the fair
value of nonfinancial assets. Additionally, the new guidance requires quantitative information about unobservable inputs, and disclosure of the valuation
processes used and narrative descriptions with regard to fair value measurements within the Level 3 categorization of the fair value hierarchy. We adopted this
accounting standard on January 1, 2012. The adoption of this new guidance did not have a material impact on our financial statements or disclosures.

Recent Accounting Guidance Not Yet Effective

In February 2013, the FASB issued ASU 2013-02 related to the reporting of amounts reclassified out of accumulated other comprehensive income that
requires entities to report, either on their income statement or in a footnote to their financial statements, the effects on earnings from items that are reclassified
out of other comprehensive income. The new guidance will be effective for the Company in the first quarter of 2013. We do not expect the adoption of this
accounting standard to have a material impact on our financial statements or disclosures.

Interest Rate Sensitivity

ITEM 7A. QUANTITATIVE AND QUALITATIVE DISCLOSURES ABOUT MARKET RISK

We had unrestricted cash and cash equivalents totaling $32.0 million at December 31, 2012. These amounts were invested primarily in money market funds
and are held for working capital purposes. We had current and non-current marketable securities holdings of $13.5 million and $3.6 million, respectively.
These amounts were invested primarily in corporate bonds, commercial paper, and United States government obligations and United States Government-
sponsored enterprise securities and are held for working capital purposes. We do not enter into investments for trading or speculative purposes. We believe we
do not have material exposure to changes in fair value as a result of changes in interest rates. Declines in interest rates, however, will reduce future investment
income. If overall interest rates fell by 10% in 2013, our interest income would have declined by approximately $28,000, assuming consistent investment
levels.

Foreign Currency Risk

Our operations include manufacturing and sales activities in the United States, Austria, Belgium, France, Germany, Italy, Japan and India, as well as research
activities in countries outside the United States, including Singapore and Hungary. Our results of operations and cash flows are subject to fluctuations due to
changes in foreign currency exchange rates. For example, we purchase materials for, and pay employees at, our research facility in Hungary in Hungarian
Forint. In addition, we purchase products for sale in the United States from foreign companies and have agreed to pay them in currencies other than the
United States dollar. As a result, our expenses and cash flows are subject to fluctuations due to changes in foreign currency exchange rates. In periods when
the United States dollar declines in value as compared to the foreign currencies in which we incur expenses, our foreign-currency based expenses increase
when translated into United States dollars. Although it is possible to do so, we have not hedged our foreign currency since the exposure has not been material
to our historical operating results. Although substantially all of our sales are denominated in United States dollars, future fluctuations in the value of the
United States dollar may affect the price competitiveness of our products outside the United States. The effect of a 10% adverse change in exchange rates on
foreign denominated receivables as of December 31, 2012 would have been a $0.2 million foreign exchange loss recognized as a component of interest
expense and other, net in our consolidated statement of operations. We may consider hedging for our foreign currency risk in the future.

Equity Price Risk

As described further in Note 4 to the consolidated financial statements, we have an investment in common shares of CO2 Solutions Inc., a company based in
Quebec City, Canada, or CO2 Solutions, whose shares are publicly traded in Canada on the TSX Venture Exchange. During 2012, we evaluated our
investment in the common shares of CO2 Solutions. At the time of the evaluation the fair value of our investment in CO2 Solutions’ common stock was $0.6
million and our carrying cost for the investment was $1.3 million and we determine the impairment was other-than-temporary considering the length of time
and extent to which the fair value had been less than our cost, the financial condition and near term prospects of CO2 Solutions, and our management’s ability
and intent to hold the securities until fair value recovers. As a result of our analysis, we recorded an impairment of $0.8 million during 2012 as an expense in
our consolidated statement of operations as selling, general and administrative expense.

This investment is exposed to fluctuations in both the market price of CO2 Solutions’ common shares and changes in the exchange rates between the United
States dollar and the Canadian dollar. The effect of a 10% adverse change in the market price of CO2 Solutions’ common shares as of December 31, 2012
would have been an unrealized loss of approximately $61,000, recognized as a component of our consolidated statement of comprehensive loss. The effect of
a 10% adverse change in the exchange rates between the United States dollar and the Canadian dollar as of December 31, 2012 would have been an
unrealized loss of approximately $61,000, recognized as a component of our consolidated statements of comprehensive loss.

The Board of Directors and Stockholders
Codexis, Inc.

Report of Independent Registered Public Accounting Firm

We have audited Codexis Inc.'s internal control over financial reporting as of December 31, 2012, based on criteria established in Internal Control-
Integrated Framework issued by the Committee of Sponsoring Organizations of the Treadway Commission (the COSO criteria). Codexis Inc.'s management
is responsible for maintaining effective internal control over financial reporting, and for its assessment of the effectiveness of internal control over financial
reporting included in the accompanying Management's report on internal control over financial reporting. Our responsibility is to express an opinion on the
company's internal control over financial reporting based on our audit.

We conducted our audit in accordance with the standards of the Public Company Accounting Oversight Board (United States). Those standards require

that we plan and perform the audit to obtain reasonable assurance about whether effective internal control over financial reporting was maintained in all
material respects. Our audit included obtaining an understanding of internal control over financial reporting, assessing the risk that a material weakness exists,
testing and evaluating the design and operating effectiveness of internal control based on the assessed risk, and performing such other procedures as we
considered necessary in the circumstances. We believe that our audit provides a reasonable basis for our opinion.

A company's internal control over financial reporting is a process designed to provide reasonable assurance regarding the reliability of financial

reporting and the preparation of financial statements for external purposes in accordance with generally accepted accounting principles. A company's internal
control over financial reporting includes those policies and procedures that (1) pertain to the maintenance of records that, in reasonable detail, accurately and
fairly reflect the transactions and dispositions of the assets of the company; (2) provide reasonable assurance that transactions are recorded as necessary to
permit preparation of financial statements in accordance with generally accepted accounting principles, and that receipts and expenditures of the company are
being made only in accordance with authorizations of management and directors of the company; and (3) provide reasonable assurance regarding prevention
or timely detection of unauthorized acquisition, use or disposition of the company's assets that could have a material effect on the financial statements.

Because of its inherent limitations, internal control over financial reporting may not prevent or detect misstatements. Also, projections of any evaluation

of effectiveness to future periods are subject to the risk that controls may become inadequate because of changes in conditions, or that the degree of
compliance with the policies or procedures may deteriorate.

A material weakness is a deficiency, or combination of deficiencies, in internal control over financial reporting, such that there is a reasonable
possibility that a material misstatement of the company's annual or interim financial statements will not be prevented or detected on a timely basis. The
following material weakness has been identified and included in management's assessment. Management has identified a material weakness in controls
related to the Company's accounting for complex, non-routine transactions. We also have audited, in accordance with the standards of the Public Company
Accounting Oversight Board (United States), the consolidated balance sheets of Codexis, Inc. as of December 31, 2012 and 2011, and the related consolidated
statements of operations, comprehensive income, redeemable convertible preferred stock and stockholders' equity (deficit) and cash flows for each of the
three years in the period ended December 31, 2012. This material weakness was considered in determining the nature, timing and extent of audit tests applied
in our audit of the 2012 consolidated financial statements, and this report does not affect our report dated April 2, 2013, which expressed an unqualified
opinion on those consolidated financial statements.

In our opinion, because of the effect of the material weakness described above on the achievement of the objectives of the control criteria, Codexis, Inc.

has not maintained effective internal control over financial reporting as of December 31, 2012, based on the COSO criteria.

The Board of Directors and Stockholders
Codexis, Inc.

Report of Independent Registered Public Accounting Firm

We have audited the accompanying consolidated balance sheets of Codexis, Inc. (the Company) as of December 31, 2012 and 2011, and the related

consolidated statements of operations, comprehensive income, redeemable convertible preferred stock and stockholders' equity (deficit) and cash flows for
each of the three years in the period ended December 31, 2012. These financial statements are the responsibility of the Company's management. Our
responsibility is to express an opinion on these financial statements based on our audits.

We conducted our audits in accordance with the standards of the Public Company Accounting Oversight Board (United States). Those standards require

that we plan and perform the audit to obtain reasonable assurance about whether the financial statements are free of material misstatement. An audit also
includes examining, on a test basis, evidence supporting the amounts and disclosures in the financial statements. An audit also includes assessing the
accounting principles used and significant estimates made by management, as well as evaluating the overall financial statement presentation. We believe that
our audits provide a reasonable basis for our opinion.

In our opinion, the financial statements referred to above present fairly, in all material respects, the consolidated financial position of Codexis, Inc. at
December 31, 2012 and 2011, and the consolidated results of its operations and its cash flows for each of the three years in the period ended December 31,
2012, in conformity with U.S. generally accepted accounting principles.

We have also audited, in accordance with the standards of the Public Company Accounting Oversight Board (United States), Codexis, Inc.'s internal

control over financial reporting as of December 31, 2012, based on criteria established in Internal Control-Integrated Framework issued by the Committee of
Sponsoring Organizations of the Treadway Commission and our report dated April 2, 2013 expressed an adverse opinion thereon.

1. Description of Business

Codexis, Inc.

Notes to Consolidated Financial Statements

We were incorporated in Delaware in January 2002. We engineer enzymes for pharmaceutical, biofuel and chemical production. Our proven technologies
enable scale-up and implementation of biocatalytic solutions to meet customer needs for rapid, cost-effective and sustainable process development, from
research to manufacturing.

We have commercialized our technology and products in the pharmaceuticals market, which is our primary business focus. There are currently over 50
pharmaceutical firms using our technology, products and services in their manufacturing process development, including in the production of some of the
world's bestselling and fastest growing drugs.

We are developing our CodeXyme® cellulase enzymes to convert non-food plant material, which we call cellulosic biomass, into affordable sugars, which can
then be converted into renewable fuels and chemicals. We are also developing our own manufacturing process for CodeXol® detergent alcohols, which are
bio-based chemicals. Detergent alcohols are used to manufacture surfactants, which are key, active cleaning ingredients in consumer products such as
shampoos, liquid soaps and laundry detergents. We are seeking collaboration partners to assist us with the development and commercialization of CodeXyme®
cellulase enzymes and CodeXol® detergent alcohols, and we are also exploring other strategic options with respect to these products and technologies.

We create our products by applying our CodeEvolver® directed evolution technology platform, which introduces genetic mutations into microorganisms,
giving rise to changes in the enzymes that they produce. Once we identify potentially beneficial mutations, we test combinations of these mutations until we
have created variant enzymes that exhibit marketable performance characteristics superior to competitive products. This process allows us to make
continuous, efficient improvements to the performance of our enzymes.

In these Notes to Consolidated Financial Statements, the “Company,” “we,” “us” and “our” refer to Codexis, Inc. and its subsidiaries on a consolidated basis.

2. Summary of Significant Accounting Policies

Basis of Presentation and Consolidation

The consolidated financial statements have been prepared in accordance with accounting principles generally accepted in the United States of America
(“GAAP”) and the applicable rules and regulations of the Securities and Exchange Commission (“SEC”) and include the accounts of Codexis, Inc. and our
wholly-owned subsidiaries. We have subsidiaries in the United States, Brazil, Hungary, India, Mauritius, The Netherlands and Singapore. All significant
intercompany balances and transactions have been eliminated in consolidation.

Significant Risks and Uncertainties

We incurred net losses of $30.9 million, $16.6 million and $8.5 million for the years ended December 31, 2012, 2011 and 2010, respectively. We used $11.9
million, $0.5 million and $16.4 million of cash in operating activities for the years ended December 31, 2012, 2011 and 2010, respectively. At December 31,
2012, we had an accumulated deficit of $215.6 million and unrestricted cash and cash equivalents of $32.0 million. We may be required to seek additional
funds through collaborations or public or private debt or equity financings, and may also seek to reduce expenses related to our operations. There can be no
assurance that any financing will be available or at terms acceptable to us.

Use of Estimates

The preparation of financial statements in conformity with GAAP requires management to make estimates and assumptions that affect the reported amounts
of assets and liabilities, disclosures of contingent liabilities at the date of the consolidated financial statements, and the reported amounts of revenues and
expenses during the reporting period. Our management regularly assesses these estimates which primarily affect revenue recognition, the valuation of
marketable securities and accounts receivable, intangible assets, goodwill arising out of business acquisitions, inventories, accrued liabilities, common stock,
and stock options and the valuation allowances associated with deferred tax assets. Actual results could differ from those estimates and such differences may
be material to the consolidated financial statements.

The assets and liabilities of foreign subsidiaries, where the local currency is the functional currency, are translated from their respective functional currencies
into United States dollars at the exchange rates in effect at the balance sheet date, with resulting foreign currency translation adjustments recorded in
consolidated statement of comprehensive loss.

Revenue and expense amounts are translated at average rates during the period. Accumulated other comprehensive income (loss) included cumulative
translation adjustment gain of $1,000 at December 31, 2012 and loss of $165,000 at December 31, 2011.

Where the United States dollar is the functional currency, nonmonetary assets and liabilities originally acquired or assumed in other currencies are recorded in
United States dollars at the exchange rates in effect at the date they were acquired or assumed. Monetary assets and liabilities denominated in other currencies
are translated into United States dollars at the exchange rates in effect at the balance sheet date. Translation adjustments are recorded in interest expense and
other, net in the accompanying consolidated statements of operations. Gains and losses realized from transactions, including intercompany balances not
considered as permanent investments, denominated in currencies other than an entity’s functional currency, are included in interest expense and other, net in
the accompanying consolidated statements of operations.

Concentrations of Credit Risk

Financial instruments that potentially subject us to significant concentrations of credit risk consist primarily of cash and cash equivalents, marketable
securities, accounts receivable and restricted cash. Cash and cash equivalents, marketable securities and restricted cash are invested through banks and other
financial institutions in the United States, as well as in other foreign countries. Such deposits may be in excess of insured limits.

Credit risk with respect to accounts receivable exists to the full extent of amounts presented in the consolidated financial statements. We periodically require
collateral to support credit sales. We estimate an allowance for doubtful accounts through specific identification of potentially uncollectible accounts
receivable based on an analysis of our accounts receivable aging. Uncollectible accounts receivable are written off against the allowance for doubtful accounts
when all efforts to collect them have been exhausted. Recoveries are recognized when they are received. Actual collection losses may differ from our
estimates and could be material to our consolidated financial position, results of operations, and cash flows.

Customers with accounts receivables balance of 10% or more of our total receivables balance consist of the following:

We do not believe the accounts receivable from these customers represent a significant credit risk based on past collection experiences and the general
creditworthiness of these customers.

Fair Value of Financial Instruments

The carrying amounts of certain of our financial instruments, including cash and cash equivalents, marketable securities, restricted cash, accounts receivable
and accounts payable, approximate fair value due to their short maturities.

Fair value is considered to be the price at which an asset could be exchanged or a liability transferred (an exit price) in an orderly transaction between
knowledgeable, willing parties in the principal or most advantageous market for the asset or liability. Where available, fair value is based on or derived from
observable market prices or other observable inputs. Where observable prices or inputs are not available, valuation models are applied. These valuation
techniques involve some level of management estimation and judgment, the degree of which is dependent on the price transparency for the instruments and
the instruments’ complexity.

Cash, Cash Equivalents and Marketable Securities

We consider all highly liquid investments with maturity dates of three months or less at the date of purchase to be cash equivalents. Cash and cash equivalents
consist of cash on deposit with banks and money market funds. The majority of cash and cash equivalents are maintained with major financial institutions in
North America. Deposits with these financial institutions may exceed the amount of insurance provided on such deposits. Marketable securities included in
current assets are comprised of corporate bonds, commercial paper, government-sponsored enterprise securities and United States Treasury obligations.
Marketable securities included in non-current assets are comprised of corporate bonds and United States Treasury obligations that have a maturity date greater
than 1 year. Our investment in common shares of CO2 Solutions Inc. (“CO2 Solutions”) is included in non-current marketable securities.

We perform separate evaluations of impaired debt and equity securities to determine if the unrealized losses as of the balance sheet date are other-than-
temporary impairment.

For our investments in equity securities, our evaluation considers a number of factors including, but not limited to, the length of time and extent to which the
fair value has been less than cost, the financial condition and near term prospects of the issuer, and our management’s ability and intent to hold the securities
until fair value recovers. The assessment of the ability and intent to hold these securities to recovery focuses on our current and forecasted liquidity
requirements, our capital requirements and securities portfolio objectives. Based on our evaluation, we concluded during the third quarter of 2012, the
unrealized losses related to our equity investment in the common shares of CO2 Solutions were other-than-temporary and as a result, we recorded $0.8 million
as a selling, general and administrative expense in our consolidated statement of operations (see Note 6). As of December 31, 2012, there were no unrealized
losses related to our equity securities.

For our investments in debt securities, our management determines whether we intend to sell or if it is more-likely-than-not that we will be required to sell
impaired securities. This determination considers our current and forecasted liquidity requirements, our capital requirements and securities portfolio
objectives. For all impaired debt securities for which there was no intent or expected requirement to sell, the evaluation considers all available evidence to
assess whether it is likely the amortized cost value will be recovered. We conduct a regular assessment of our debt securities with unrealized losses to
determine whether the securities have other-than-temporary impairment considering, among other factors, the nature of the securities, credit rating or financial
condition of the issuer, the extent and duration of the unrealized loss, expected cash flows of underlying collateral and market conditions. As of December 31,
2012, there were no unrealized losses related to our debt securities.

Our investments in debt and equity securities are classified as available-for-sale and are carried at estimated fair value. Unrealized gains and losses are
reported on the consolidated statement of comprehensive loss unless considered other-than-temporary. Amortization of purchase premiums and accretion of
purchase discounts, realized gains and losses of debt securities and declines in value deemed to be other-than-temporary, if any, are included in interest
income or interest expense and other, net. The cost of securities sold is based on the specific-identification method. There were no significant realized gains or
losses from sales of marketable securities during the years ended December 31, 2012, 2011, and 2010.

Accounts Receivable

Accounts receivable represent amounts owed to us under our collaborative research and development agreements, product revenues and government awards.
Our allowance for doubtful accounts was $150,000 and $17,000 as of December 31, 2012 and 2011, respectively. Specific accounts written off against the
established reserve were $0, $12,000, and $0 during the years ended December 31, 2012, 2011 and 2010, respectively.

Inventories

Inventories consist of biocatalysts, which are enzymes or microbes that facilitate chemical reactions, and pharmaceutical intermediates. Internally produced
biocatalysts only qualify as commercial inventory after they have achieved specifications that are required for selling the materials. Inventories held at our
contract manufacturers are accepted as finished goods after achieving specifications stated in our purchase orders. Inventories are carried at the lower of cost
or market. Cost is determined using the first-in first-out method or the specific identification method depending on location. Inventories, based on demand
and age, are written down as excess and obsolete materials, if necessary.

Prepaid Expenses and Other Current Assets

Included in prepaid expenses and other current assets was $1.1 million in deferred cost of sales related to a sales arrangement with a customer that was
deferred due to extended payment terms. This amount will be deferred until payment is received.

Impairment of Long-Lived Assets and Intangible Assets

Long-lived and intangible assets with finite lives are reviewed for impairment whenever events or changes in circumstances indicate the carrying amount of
an asset may not be recoverable. Recoverability of these assets is measured by comparison of their carrying amounts to future undiscounted cash flows the
assets are expected to generate.

The Company's intangible assets with finite lives consist of customer relationships, developed core technology, trade names, and the intellectual property
(“IP”) rights associated with the acquisition of Maxygen's directed evolution technology in 2010. Intangible assets were recorded at their fair values at the
date we acquired the assets and, for those assets having finite useful lives, are amortized using the straight-line method over their estimated useful lives. The
Company's long-lived assets include property, plant and equipment, and other non-current assets.

We determined that we have a single entity wide asset group (“Asset Group”). The directed evolution technology patent portfolio acquired from Maxygen
(“Core IP”) is the most significant component of the Asset Group since it is the base technology for all aspects of our research and development, and
represents the basis for all of our identifiable cash flow generating capacity. Consequently, we do not believe that identification of independent cash flows
associated with our long-lived assets is currently possible at any lower level than the Asset Group.

The Core IP is the only finite-lived intangible asset on our balance sheet as of December 31, 2012 and is considered the primary asset within the Asset Group.
The remaining useful life of the Core IP extends through the fourth quarter of 2016. There has been no significant change in the utilization or estimated life of
our Core IP since we acquired the technology patent portfolio from Maxygen. The estimated remaining useful life of our Core IP is not impacted by the
termination of the Shell Research Agreement.

The carrying value of our long-lived assets in the Asset Group may not be recoverable based upon the existence of one or more indicators of impairment
which could include: a significant decrease in the market price of the Company's common stock; current period cash flow losses or operating losses combined
with a history of losses or a forecast of continuing losses associated with the use of the assets; slower growth rates in our industry; significant adverse changes
in the business climate or legal factors; accumulation of costs significantly in excess of the amount originally expected for the acquisition or construction of
the assets; loss of significant customers or partners; or the current expectation that the assets will more likely than not be sold or disposed of significantly
before the end of their estimated useful life.

We evaluate recoverability of our long-lived assets and intangible assets based on the sum of the undiscounted cash flows expected to result from the use, and
the eventual disposal of, the Asset Group. We make estimates and judgments about the future undiscounted cash flows over the remaining useful life of the
Asset Group. Our anticipated future cash flows include our estimates of existing or in process product revenues, production and operating costs, future capital
expenditures, working capital needs, and assumptions regarding the ultimate sale of the Asset Group at the end of the life of the primary asset. The useful life
of the Asset Group was based on the remaining useful life of the Core IP, the primary asset.

As of December 31, 2012 we determined that our continued operating losses and the termination of the Shell Research Agreement were indications of
impairment. Consequently, we tested our long-lived assets and intangible assets for impairment as of December 31, 2012.

As part of a comprehensive strategic planning exercise the Company undertook in the fourth quarter of 2012 and early 2013, we developed a detailed multi-
year operating plan of both revenue and expense. Our best-estimate of future cash flows used to test the recoverability of the Asset Group as of December 31,
2012 was developed directly from this plan using a forecast

76

 
 
 
 
 
Table of Contents

period consistent with the remaining useful life of the Core IP. Although our cash flow forecasts are based on assumptions that are consistent with our plans,
there is significant exercise of judgment involved in determining the cash flows attributable to our Asset Group over its estimated remaining useful life.

The undiscounted cash flows included revenue and expense from our core pharmaceutical business and other enzyme markets adjacent to our pharmaceutical
business. These adjacent enzyme businesses, which will leverage our Core IP and pharmaceutical technology and processes, include business opportunities in
the fine chemical and enzymatic therapeutic markets.

We typically receive revenues from our core pharmaceutical business and expect to receive revenues from other enzyme markets adjacent to our
pharmaceutical business in the form of one or more of the following: up-front payments, milestone payments, payments based upon the number of full-time
employee equivalents, or FTEs, engaged in related research and development activities and licensing fees and royalties. Our best estimate of future cash flows
does not include any CodeXol® and CodeXyme® revenues associated with collaboration research and development agreements, but does include an estimate
of cash flows from potential strategic transactions with respect to our CodeXyme® and CodeXol® programs, as described below.

Approximately 69% and 31% of total Company revenues included in our estimated undiscounted cash flows (excluding cash flows from potential strategic
transactions with respect to our CodeXyme® and CodeXol® programs) over the remaining useful life of the Core IP are derived from our core pharmaceutical
business and adjacent enzyme opportunities, respectively.

Our core pharmaceutical business revenues are estimated based on existing commercial relationships, signed agreements or contracts, and conservative
estimates for the capture of additional market share that management determined to be reasonably achievable. For existing and in process customer revenues
we assumed a modest rate of growth based on our historical business model for our core pharmaceutical business, including research and development
services revenue from partners and customers, which management determined to be reasonably achievable. We have historically worked closely with our
pharmaceutical partners, such as Merck, to evolve, engineer and develop enzymes that meet their specific needs. Our business model is based on having our
partners and customers pay in whole or in part for the research and development required to engineer the enzymes required.

In determining which adjacent enzyme markets to exploit, management assessed various segments of the large and growing enzyme markets and selected
those adjacent markets where we already had entry points through our existing pharmaceutical business relationships, such as fine chemicals and enzymatic
therapeutics markets. Estimated revenues associated with these adjacent markets are based on market penetration and adoption rates that management
determined to be reasonably achievable.

We calculated our expected residual value in 2016 by applying a Gordon Growth Model to our estimated 2016 normalized net cash flows using a discount
rate of 18% (“Estimated Weighted-Average Cost of Capital”), long term growth rate of 2%, and a capitalization factor of 6.25. The 18% discount rate reflects
the nature and the risk of the underlying forecast, and includes such financial components as the risk free rate, systemic stock price risk based on an
evaluation with peer companies (“beta”), equity risk premium, size premium, and company specific risk. The long term growth rate of 2% reflects projected
inflation and general economic conditions. Based on these estimates, judgments, and factors, we determined that the residual value included in the
undiscounted cash flows was $72.3 million.

We also included in the undiscounted cash flows an estimate of cash flows from potential strategic transactions with respect to our existing CodeXyme®
cellulase enzymes and CodeXol® detergent alcohols programs. The amount of estimated cash flows was determined by probability weighting different
scenarios to derive at a weighted average of most probable outcomes, with CodeXol® and CodeXyme® representing 11% and 27%, respectively, of the total
undiscounted cash flows associated with the Asset Group. These amounts are not based on any existing signed contracts or agreements.

The result of our fourth quarter 2012 impairment analysis indicates that the undiscounted cash flows for the Asset Group are greater than the carrying value of
the Asset Group by approximately 14%.

Any inability to align future production costs, operating costs, capital expenditures and working capital needs with significant changes in the timing and/or
level of estimated future revenue could adversely impact our projected undiscounted cash flows. Future changes in the estimated useful life of our long-lived
assets could also adversely impact our projected undiscounted cash flows and result in future impairment charges. If it is determined that the Asset Group is
not recoverable, an impairment loss would be calculated based on the excess of the carrying amount of the intangible and long-lived assets over the fair value.
Any future impairment charges could have a material adverse effect on our financial position and results of operations.

Impairment of Goodwill

77

Table of Contents

Goodwill represents the excess of the purchase price over the fair value of assets acquired and liabilities assumed. Goodwill is presumed to have an indefinite
life and is not subject to amortization. Goodwill is reviewed for impairment annually and whenever events or changes in circumstances indicate that the
carrying value of the goodwill may not be recoverable.

We determined that the Company has only one operating segment and reporting unit under the criteria in ASC 280, Segment Reporting, and accordingly, all of
our goodwill is associated with the Company. Our review of goodwill for indicators of impairment is performed at the Company level.

The goodwill impairment test consists of a two-step process. The first step of the goodwill impairment test, used to identify potential impairment, compares
the fair value of the reporting unit to its carrying value. If the fair value of the reporting unit exceeds its carrying amount, goodwill of the reporting unit is
considered not impaired, and the second step of the impairment test is not required.

We use our market capitalization as an indicator of fair value. We believe that since our reporting unit is publicly traded, the ability of a controlling
shareholder to benefit from synergies and other intangible assets that arise from control might cause the fair value of our reporting unit as a whole to exceed
its market capitalization. However, we believe that the fair value measurement need not be based solely on the quoted market price of an individual share of
our common stock, but also can consider the impact of a control premium in measuring the fair value of our reporting unit.

Should our market capitalization be less than our total stockholder's equity as of our annual test date or as of any interim impairment testing date, we would
also consider market comparables, recent trends in our stock price over a reasonable period and, if appropriate, use an income approach (discounted cash
flow) to determine whether the fair value of our reporting unit is greater than our carrying amount.

If we were to use an income approach we would establish a fair value by estimating the present value of our projected future cash flows expected to be
generated from our business. The discount rate applied to the projected future cash flows to arrive at the present value would be intended to reflect all risks of
ownership and the associated risks of realizing the stream of projected future cash flows. Our discounted cash flow methodology would consider projections
of financial performance for a period of several years combined with an estimated residual value. The most significant assumptions we would use in a
discounted cash flow methodology are the discount rate, the residual value and expected future revenues, gross margins and operating costs, along with
considering any implied control premium.

The second step, if required, compares the implied fair value of the reporting unit goodwill with the carrying amount of that goodwill. If the carrying amount
of the reporting unit's goodwill exceeds its implied fair value, an impairment charge is recognized in an amount equal to that excess. Implied fair value is the
excess of the fair value of the reporting unit over the fair value of all identified assets and liabilities.

Goodwill was tested for impairment as of October 1, 2012, the date of the Company's annual impairment review. The Company concluded that the fair value
of the reporting unit exceeded the carrying value and no impairment existed. No impairment charges were recorded during the years ended December 31,
2012, 2011 and 2010.

Restricted Cash

Restricted cash consisted of amounts invested in money market accounts primarily for purposes of securing a standby letter of credit as collateral for our
Redwood City, California facility lease agreement and for the purpose of securing a working capital line of credit. Restricted cash was unchanged during the
year ended December 31, 2012. During the year ended December 31, 2011, restricted cash increased by $45,000 due to changes in our facility lease
agreement and our working capital line of credit.

Revenue Recognition

Revenues are recognized when the four basic revenue recognition criteria are met: (1) persuasive evidence of an arrangement exists; (2) products have been
delivered, transfer of technology has been completed or services have been rendered; (3) the fee is fixed or determinable; and (4) collectability is reasonably
assured.

Our primary sources of revenues consist of collaborative research and development agreements, product revenues and government awards. Collaborative
research and development agreements typically provide us with multiple revenue streams, including up-front fees for licensing, exclusivity and technology
access, fees for FTE services and the potential to earn milestone payments upon achievement of contractual criteria and royalty fees based on future product
sales or cost savings by our customers. Our collaborative research and development revenues consist of revenues from Shell and revenues from other
collaborative research and development agreements.

For each source of collaborative research and development revenues, product revenues and award revenues, we apply the following revenue recognition
criteria:

•

•

•

•

•

Up-front fees received in connection with collaborative research and development agreements, including license fees, technology access fees,
and exclusivity fees, are deferred upon receipt, are not considered a separate unit of accounting and are recognized as revenues over the relevant
performance periods.

Revenues related to FTE services recognized as research services are performed over the related performance periods for each contract. We are
required to perform research and development activities as specified in each respective agreement. The payments received are not refundable
and are based on a contractual reimbursement rate per FTE working on the project. When up-front payments are combined with FTE services in
a single unit of accounting, we recognize the up-front payments using the proportionate performance method of revenue recognition based upon
the actual amount of research and development labor hours incurred relative to the amount of the total expected labor hours to be incurred by us,
up to the amount of cash received. In cases where the planned levels of research services fluctuate substantially over the research term, we are
required to make estimates of the total hours required to perform our obligations. Research and development expenses related to FTE services
under the collaborative research and development agreements approximate the research funding over the term of the respective agreements.

A payment that is contingent upon the achievement of a substantive milestone is recognized in its entirety in the period in which the milestone is
achieved. A milestone is an event (i) that can only be achieved based in whole or in part on either our performance or on the occurrence of a
specific outcome resulting from our performance, (ii) for which there is substantive uncertainty at the date the arrangement is entered into that
the event will be achieved, and (iii) results in additional payments being due to us. Milestones are considered substantive when the consideration
earned from the achievement of the milestone (i) is commensurate with either our performance to achieve the milestone or the enhancement of
value of the item delivered as a result of a specific outcome resulting from our performance, (ii) relates solely to past performance, and (iii) is
reasonable relative to all deliverable and payment terms in the arrangement.

Other payments received for which such payments are contingent solely upon the passage of time or the result of a collaborative partner’s
performance are recognized as revenue when earned in accordance with the contract terms and when such payments can be reasonably estimated
and collectability is reasonably assured.

We recognize revenues from royalties based on licensees’ sales of products using our technologies. Royalties are recognized as earned in
accordance with the contract terms when royalties from licensees can be reasonably estimated and collectability is reasonably assured.

We generate a significant percentage of our sales in India and other emerging markets. Customers in these countries are subject to significant
economic and other challenges that affect their cash flow, and many customers outside the United States are generally accustomed to vendor
financing in the form of extended payment terms which may exceed contractual payment terms. To remain competitive in markets outside the
United States, we may offer selected customers such payment flexibility. We consider arrangements with extended payment terms not to be
fixed or determinable, and accordingly, we defer revenue until payment is received. The costs associated with such revenue deferral are also
deferred and classified as other current assets in the financial statements.

Product revenues are recognized once passage of title and risk of loss has occurred and contractually specified acceptance criteria have been
met, provided all other revenue recognition criteria have also been met. Product revenues consist of sales of biocatalysts, intermediates, active
pharmaceutical ingredients and Codex Biocatalyst Panels and Kits. Cost of product revenues includes both internal and third party fixed and
variable costs including amortization of purchased technology, materials and supplies, labor, facilities and other overhead costs associated with
our product revenues.

We licensed mutually agreed upon third party technology for use in our research and development collaboration with Shell. We recorded the
license payments to research and development expense and offset by the related reimbursements received from Shell. These payments made by
Shell to us are direct reimbursements of our costs. We accounted for these direct reimbursable costs as a net amount, whereby no expense or
revenue is recorded for the costs reimbursed by Shell. For any payments not reimbursed by Shell, we recognized these as expenses in the
statement of operations. We elected to present the reimbursements from Shell as a component of our research and development expense since
presenting the receipt of payment from Shell as revenues does not reflect the substance of the arrangement.

We receive payments from government entities for work performed in the form of government awards. Government awards are agreements that
generally provide us with cost reimbursement for certain types of expenditures in return for research and development activities over a
contractually defined period. Revenues from government awards are recognized in the period during which the related costs are incurred,
provided that the conditions under which the government awards were provided have been met and we have only perfunctory obligations
outstanding.

Shipping and handling costs charged to customers are recorded as revenues. Shipping costs are included in our cost of product revenues. Such
charges were not significant in any of the periods presented.

Milestone revenue

During 2012, we recognized, in collaborative research and development revenue, $1.0 million of milestone revenue from one of our pharmaceutical partners
related to the use of our enzymes in its manufacturing processes. We received no other milestone revenue during the year ended December 31, 2012. We
recorded milestone revenues of $5.6 million and $7.8 million for the years ended December 31, 2011 and 2010, respectively, which primarily related to
collaborative research and development with Shell.

We evaluated the nature of the milestone triggering the contingent payment, and concluded that the amount can be recognized as a milestone payment based
on the facts that (i) the milestone was achieved through successful performance by us, (ii) the milestone was at risk at the inception of the arrangement, (iii)
the milestone was substantive in nature and is non-refundable, (iv) substantial effort was required by us to complete the milestone, (v) the amount of
milestone payment is reasonable in relation to the value created in achieving the milestone, and (vi) the milestone payment relates solely to past performance.
No further milestones payments are expected under this arrangement from this pharmaceutical partner.

Change in accounting estimate - United States Government awards

We recognize United States Government award revenue based on reimbursable costs incurred. Reimbursable costs include only allocable, allowable and
reasonable costs, as determined in accordance with the Federal Acquisition Regulations and the related Cost Accounting Standards as applicable to the United
States Government award. Costs incurred include direct labor and materials that are directly associated with the individual award plus indirect overhead and
general and administrative type costs based upon our provisional indirect billing rates submitted by us to the United States Department of Energy (“DOE”).
Our provisional indirect billing rates are subject to audit by the DOE. Changes in estimates affecting reimbursable costs are recognized in the period in which
the change becomes known.

During 2011, our provisional indirect billing rates for the award from the DOE under the ARPA-E Recovery Act were audited by the DOE resulting in a
revision to our provisional indirect billing rates. The revised indirect rates were subsequently

80

Table of Contents

approved by the DOE during the first quarter of 2012. As a result of this change in accounting estimate, we invoiced and recognized $530,000 of additional
award revenues during the first quarter of 2012 for reimbursable costs incurred by us in 2010 and 2011. The term of the award agreement concluded in June
2012 and no further revenue has been recognized since that date.

We rely on a limited number of suppliers for our products. We believe that other vendors would be able to provide similar products; however, the qualification
of such vendors may require substantial start-up time. In order to mitigate any adverse impacts from a disruption of supply, we attempt to maintain an
adequate supply of critical single-sourced materials. For certain materials, our vendors maintain a supply for us. We outsource the commercial scale
manufacturing of our products to contract manufacturers with facilities in Austria, India and Italy.

Research and Development Expenses

Research and development expenses consist of costs incurred for internal projects as well as partner-funded collaborative research and development activities.
These costs include direct and research-related overhead expenses, which include salaries, stock-based compensation and other personnel-related expenses,
facility costs, supplies, depreciation of facilities and laboratory equipment, as well as research consultants and the cost of funding research at universities and
other research institutions, and are expensed as incurred. Costs to acquire technologies that are utilized in research and development that have no alternative
future use, are expensed when incurred.

Advertising

Advertising costs are expensed as incurred and included in selling, general and administrative expenses in the consolidated statements of operations.
Advertising costs were $351,000, $113,000, and $55,000 for the years ended December 31, 2012, 2011, and 2010, respectively.

Income Taxes

We use the liability method of accounting for income taxes. Deferred tax assets and liabilities are recognized for the estimated future tax consequences
attributable to differences between the consolidated financial statement carrying amounts of existing assets and liabilities and their respective tax bases.
Deferred tax assets are recognized for deductible temporary differences, along with net operating loss ("NOL") carryforwards, if it is more likely than not that
the tax benefits will be realized. To the extent a deferred tax asset cannot be recognized under the preceding criterion, a valuation allowance is established.
Deferred tax assets and liabilities are measured using enacted tax rates in effect for the year in which those temporary differences are expected to be recovered
or settled.

We recognize the financial statement effects of an uncertain tax position when it is more likely than not, based on the technical merits, that the position will be
sustained upon examination.

Stock-Based Compensation

We recognize compensation expense related to share-based transactions, including the awarding of employee stock options, based on the estimated fair value
of the awards granted. All awards granted, modified or settled after January 1, 2006 have been accounted for based on the fair value of the awards granted.
We generally use the straight-line method to allocate stock-based compensation expense to the appropriate reporting periods. Some awards are accounted for
using the accelerated method as appropriate for the terms of the awards.

81

 
 
 
 
 
   
   
Table of Contents

We account for stock options issued to non-employees based on their estimated fair value determined using the Black-Scholes option-pricing model. The fair
value of the options granted to non-employees is re-measured as they vest, and the resulting change in value, if any, is recognized as an increase or decrease
in stock compensation expense during the period the related services are rendered.

Net Loss per Share of Common Stock

Basic net loss per share of common stock is computed by dividing the net loss by the weighted-average number of shares of common stock outstanding

effect to all potential common shares, consisting of stock options, warrants and redeemable convertible preferred stock, to the extent dilutive. Basic and

Certain amounts in prior period financial statements related to Shell including related party collaboration revenue (see Note 3), related party receivable and
related party deferred revenue, have been reclassified to the corresponding non-related party account, since effective July 1, 2011, Shell is no longer
considered a related party (see Note 7). Our investment in CO2 Solutions (See Note 4), has been reclassified from non-current other assets to non-current
marketable securities and the composition of our deferred tax assets have been reclassified to conform to the current period presentation.

Accounting Guidance Update

Recently Adopted Accounting Guidance

In September 2011, the FASB issued ASU 2011-08 that simplifies goodwill impairment tests. The new guidance states that a “qualitative” assessment may be
performed to determine whether further impairment testing is necessary. We adopted this accounting standard January 1, 2012, and the adoption of this
guidance did not have a material impact to our financial statements or disclosures.

In June 2011, the FASB issued ASU 2011-05 that eliminates the option to present items of other comprehensive income (“OCI”) as part of the statement of
changes in stockholders’ equity, and instead requires either, OCI presentation and net

82

 
 
 
 
 
   
   
 
   
   
 
 
 
 
Table of Contents

income in a single continuous statement in the statement of operations, or as a separate statement of comprehensive income. This new guidance is effective
for fiscal years, and interim periods within those years, beginning after December 15, 2011, with early adoption permitted. We adopted this update in the
fourth quarter of 2012. The adoption of this accounting guidance did not have a material impact on our financial statements.

In May 2011, the FASB issued ASU 2011-04 that clarifies and changes some fair value measurement principles and disclosure requirements. Among them is
the clarification that the concepts of highest and best use and valuation premise in a fair value measurement, should only be applied when measuring the fair
value of nonfinancial assets. Additionally, the new guidance requires quantitative information about unobservable inputs, and disclosure of the valuation
processes used and narrative descriptions with regard to fair value measurements within the Level 3 categorization of the fair value hierarchy. We adopted this
accounting standard on January 1, 2012. The adoption of this new guidance did not have a material impact on our financial statements or disclosures.

Recent Accounting Guidance Not Yet Effective

In February 2013, the FASB issued ASU 2013-02 related to the reporting of amounts reclassified out of accumulated other comprehensive income that
requires entities to report, either on their income statement or in a footnote to their financial statements, the effects on earnings from items that are reclassified
out of other comprehensive income. The new guidance will be effective for the Company in the first quarter of 2013. We do not expect the adoption of this
accounting standard to have a material impact on our financial statements or disclosures.

3. Collaborative Research and Development Agreements

Shell and Raízen

In November 2006, we entered into a collaborative research agreement and a license agreement with Shell to develop biocatalysts and associated processes
that use such biocatalysts.

In November 2007, we entered into a new and expanded five-year collaborative research agreement (“Shell Research Agreement”) and a license agreement
(the “Shell License Agreement”) with Shell. In connection with the Shell Research Agreement, we agreed to use our proprietary technology platform to
discover and develop enzymes and microorganisms for use in converting cellulosic biomass into biofuels and related products and Shell agreed to pay us (i)
research funding at specified rates per FTE working on the project during the research term, (ii) milestone payments upon the achievement of milestones, and
(iii) royalties on future product sales. The Shell Research Agreement also specified certain minimum levels of FTE services that we were required to allocate
to the collaboration efforts that increased over the term of the agreement, which was originally set to expire on November 1, 2012.

In September 2012, we entered into an agreement with Shell (the “New Shell Agreement”) which among other things, terminates the Shell Research
Agreement effective as of August 31, 2012, except for certain provisions of the Shell Research Agreement which will survive such termination, including
provisions regarding intellectual property rights, patent prosecution and maintenance, confidentiality and indemnification. The New Shell Agreement required
Shell to pay us approximately $7.5 million as full, complete and final satisfaction of amounts that Shell may have owed us under the Shell Research
Agreement with respect to (i) FTEs assigned to the Shell Research Agreement and (ii) milestones achieved or achievable by us under the Shell Research
Agreement. The $7.5 million was recognized as revenue during the third quarter of 2012 when all of our obligations were fulfilled under the New Shell
Agreement and was collected during the fourth quarter of 2012.

Beginning September 1, 2012, we have no further obligations to Shell under the Shell Research Agreement to provide any FTEs to perform work under or
after the collaboration and Shell has no future obligations to us under the Shell Research Agreement to provide funding for FTEs to perform work under or
after the collaboration. We remain eligible to receive a one-time $3.0 million payment from Shell under the Shell Research Agreement upon the first sale by
Shell of a product in the field of converting cellulosic biomass into fermentable sugars in Brazil, or in the fields of converting fermentable sugars derived
from biomass into liquid fuel or liquid fuel additives or into lubricants.

Under the New Shell Agreement, Shell granted us royalty-bearing, non-exclusive rights and licenses to develop, manufacture, use and sell enzymes and
microbes in the field of converting cellulosic biomass into fermentable sugars on a worldwide basis, except for Brazil, where such sugars are converted into
liquid fuels, fuel additives or lubricants (the “Field of Use”). Raízen holds the exclusive rights to use our enzymes and microbes for converting cellulosic
biomass into fermentable sugars in Brazil, where such sugars are converted into ethanol. Following the date on which our biocatalysts are used to produce
sugars used in the Field of Use sufficient to produce 30.0 million gallons of liquid fuel, we will be required to pay Shell a royalty on our sales to third parties
of our enzymes and microbes in the Field of Use, equal to a low single-digit percentage of net sales and we will also be required to pay Shell a royalty on our
use of biocatalysts in the Field of Use, equal to a low single-digit percentage of

83

Table of Contents

our applicable net sales of such enzymes or microbes. Shell is also entitled to discounted pricing under the New Shell Agreement for biocatalysts purchased
from us by Shell for use in the Field of Use, but we are under no obligation to sell such biocatalysts to Shell.

Under the New Shell Agreement, we also granted to Shell a non-exclusive, royalty-free license to manufacture, use and import, solely for the use of Shell and
its affiliates, (i) enzymes developed by us during the ten year period following August 31, 2012 outside of the Shell Research Agreement for use in the Field
of Use and (ii) improvements to any microbe developed by us during the ten year period following August 31, 2012 outside of the Shell Research Agreement
that is derivative of an identified microbe for use in the Field of Use. Shell remains subject to existing royalty obligations to us for future sales of products
covered by the intellectual property and technology that remain exclusively licensed to Shell under the License Agreement.

Additionally, with respect to each invention relating to technology or materials regarding novel liquid fuel compounds, liquid fuel additives or lubricants,
Shell will continue to be required to work exclusively with us, for a period of three years after the first nonprovisional patent application filing for such
invention, to identify biological methods of synthesis of the compound(s) that are claimed, or whose use as a liquid fuel compound, additive or lubricant, is
claimed, in such patent filing.

The New Shell Agreement has a term that commences on August 31, 2012 and continues until the later of August 31, 2032 or the date of the last to expire
patent rights included in our collaboration that claim a biocatalyst or a microbe for use in the Field of Use.

Prior to the New Shell Agreement, Shell had an obligation under the Shell Research Agreement to fund us at specified rates for each FTE, which as of August
2012, were equal to $460,000 on an annual basis for each FTE in the United States and $399,000 on an annual basis for each FTE in Hungary. As of August
31, 2012, the number of FTEs assigned to our collaboration with Shell was 116.

In accordance with our revenue recognition policy, the $20.0 million up-front exclusivity fee and the research funding fees to be received for FTE services are
recognized in proportion to the actual research efforts incurred relative to the amount of total expected effort to be incurred by us over the five-year research
period commencing November 2007. Milestones payments to be earned under this agreement were determined to be at risk at the inception of the
arrangement and substantive and are expected to be recognized upon achievement of the applicable milestone and when collectability of such payment is
reasonably assured. There are no further milestone payments under the Shell Research Agreement, other than a $3.0 million milestone payment described
above for which we may become eligible. We recorded milestone revenues of zero, $5.6 million and $7.4 million during the years ended December 31, 2012,
2011 and 2010, respectively.

Under the Shell Research Agreement and Shell License Agreement, we had the right, if mutually agreed upon with Shell, to license technology from third
parties that would assist us in meeting objectives under the collaboration and Shell was obligated to reimburse us for the licensing costs of the technology.
Payments made by us to the third-party providers were recorded as research and development expenses related to our collaborative research agreement with
Shell. Shell reimbursed us for licensing costs of $424,000, $199,000, and $1.4 million for the years ended December 31, 2012, 2011 and 2010, respectively.
We record these reimbursements against the costs incurred.

In June 2011, Shell completed the transfer of all of its equity interests in us, together with the associated right to appoint one member to our board of
directors, to Raízen, Shell’s joint venture with Cosan S.A. Indústria e Comércio, (“Cosan”) in Brazil. As a result, Shell is no longer considered a related party.
Notwithstanding the above, Shell did not transfer the Shell Research Agreement to Raízen. Additionally in September 2011, we entered into a joint
development agreement directly with Raízen. Work under this joint development agreement has been completed and we do not expect this project to continue.

Manufacturing Collaboration

In February 2010, we consolidated certain of the contractual terms in our then-existing agreements with Arch by simultaneously terminating all of our
existing agreements with Arch, other than the Master Services Agreement with Arch entered into as of August 1, 2006, and entering into amended agreements
with Arch. The amended agreements, among other things, provided for biocatalysts supplied from us to Arch and intermediates supplied from Arch to us. We
sold biocatalysts to Arch at an agreed upon price, and Arch manufactured intermediates on our behalf. Arch sold the intermediates to us at a formula-based or
at an agreed upon price. We then directly marketed and sold the intermediates to a specified group of customers in the generic pharmaceutical industry. Under
the amended agreements, Arch also sold intermediates directly to other customers, and a license royalty was owed by Arch to us based on the volume of
product they sold to us and to their other customers. Royalties earned from Arch under this arrangement were $127,000 and $752,000 for the years ended
December 31, 2012 and 2011, respectively.

In November 2012, we entered into a new commercial arrangement with Arch by simultaneously terminating all of our existing supply agreements with Arch
and entering into the New Arch Enzyme Supply Agreement pursuant to which Arch agreed to exclusively purchase enzymes from us for use in the
manufacture of certain of Arch’s products and we agreed to exclusively supply, with limited exceptions, certain of our enzymes to Arch at an agreed upon
price for use in such manufacture. Under the New Arch Enzyme Supply Agreement, Arch will no longer produce atorva-family active pharmaceutical
ingredients (“APIs”) and intermediates for us and Arch will no longer pay us royalties on their sale of such APIs and intermediates to customers and we will
no longer have exclusive rights to market such APIs and intermediates in certain markets.

4. Joint Development Agreement with CO2 Solutions

On December 15, 2009, we entered into an exclusive joint development agreement with CO2 Solutions, a company based in Quebec City, Quebec, Canada,
whose shares are publicly traded in Canada on TSX Venture Exchange. The joint development agreement expired in January 2011. Under the agreement, we
obtained a research license to CO2 Solutions’s intellectual property and agreed to conduct research and development activities jointly with CO2 Solutions with
the goal of advancing the development of carbon management technology. We also purchased 10,000,000 common shares (approximately 16.6% of the total
common shares outstanding at the time of investment) of CO2 Solutions in a private placement subject to a four-month statutory resale restriction. This
restriction expired on April 15, 2010. In July 2012, Alan Shaw, our former Chief Executive Officer resigned from the board of directors of CO2 Solutions and
we are currently considering potential replacements to this designated board seat.

In January 2011, we extended our joint development agreement with CO2 Solutions on essentially the same terms as the original agreement. The extended
agreement expires nine months after the expiry of any third party collaborations. This agreement expired in February 2013.

We concluded that through December 31, 2012, we did not have the ability to exercise significant influence over CO2 Solutions’ operating and financial
policies. We consider our investment in CO2 Solutions’ common shares as an investment in a marketable security that is available for sale, and carry it at fair
value in non-current marketable securities. As discussed in Note 6, we recorded an impairment of $0.8 million in our consolidated statement of operations as
selling, general and administrative expense during the year ended December 31, 2012 with respect to this investment. Subsequent changes in fair value have
been recognized in the consolidated statement of comprehensive loss. The fair value of our CO2 Solutions' common shares as of December 31, 2012 was
determined by trading on TSX Venture Exchange. Accordingly, we have classified our investment in CO2 Solutions as a Level 1 investment as discussed in
Note 6.

Due to the extension of the lease period for certain currently occupied facilities, we re-evaluated the depreciable lives of existing leasehold improvements,
totaling $2.3 million in net book value at the time of reassessment in February 2011. Since leasehold improvements are typically depreciated over the lesser of
the assets’ useful life or the remaining lease period, the extension of contracted facilities leases through 2020 necessitated a change in our estimate of
depreciable lives on leasehold improvements. While some lives have been shortened under this reassessment with the vacating of a portion of our facilities,
the majority of depreciable lives have been extended up to as much as 5 years from the assets’ in service date, in accordance with our leasehold
improvements’ standard useful lives. The net effect of this reassessment is lower monthly depreciation being recognized on leasehold improvements over a
longer period of time. These changes’ net effect on depreciation expense recognized is not expected to be material on a quarterly or annual basis.

Assets and liabilities recorded at fair value in the consolidated financial statements are categorized based upon the level of judgment associated with the
inputs used to measure their fair value. Hierarchical levels which are directly related to the amount of subjectivity associated with the inputs to the valuation
of these assets or liabilities are as follows:

Level 1 — Inputs that are unadjusted, quoted prices in active markets for identical assets or liabilities at the measurement date.

Level 2 — Inputs (other than quoted prices included in Level 1) that are either directly or indirectly observable for the asset or liability through

correlation with market data at the measurement date and for the duration of the instrument’s anticipated life.

Table of Contents

Level 3 — Unobservable inputs that are supported by little or no market activity and that are significant to the fair value of the assets or liabilities and

which reflect management’s best estimate of what market participants would use in pricing the asset or liability at the measurement date.

For Level 2 financial investments, our investment advisor provides us with monthly account statements documenting the value of each investment

based on prices received from an independent third-party valuation service provider. This third party evaluates the types of securities in our investment
portfolio and calculates a fair value using a multi-dimensional pricing model that includes a variety of inputs, including quoted prices for similar assets and
liabilities in active markets, quoted prices for identical or similar assets or liabilities in markets that are not active, interest rates and yield curves observable at
commonly quoted intervals, volatilities, prepayment speeds, loss severities, credit risks and default rates that are observable at commonly quoted intervals. As
we are ultimately responsible for the determination of the fair value of these instruments, we perform quarterly analyses using prices obtained from another
independent provider of financial instrument valuations, to validate that the prices we have used are reasonable estimates of fair value.

We estimated the fair value of our investment in 10,000,000 common shares of CO2 Solutions using the market value of common shares as determined by
trading on the TSX Venture Exchange. Accordingly, we have classified our investment in CO2 Solutions as a Level 1 investment. As of December 31, 2012,
the fair value of our investment in CO2 Solutions’ common stock was $0.6 million with an unrealized gain of $47,000. During 2012, we evaluated our
investment in the common shares of CO2 Solutions and determined the impairment was other-than-temporary considering the length of time and extent to
which the fair value has been less than our cost, the financial condition and near term prospects of CO2 Solutions, and our management’s ability and intent to
hold the securities until fair value recovers. As a result of our analysis, we recorded an impairment of $0.8 million during the year ended December 31, 2012
as an expense in our consolidated statement of operations as selling, general and administrative expense. At December 31, 2011, the estimated fair value of
our investment in CO2 Solutions' common stock was $1.2 million and the unrealized loss was $155,000.

Maxygen was one of our stockholders until it distributed its holdings to its stockholders in December 2010, and so transactions between us and Maxygen
prior to that time were considered related party transactions. In October of 2010, we acquired Maxygen’s directed evolution technology patent portfolio for
net consideration of $20.2 million including $20.0 million paid to Maxygen, transaction costs of $0.7 million and a royalty payable extinguishment of $0.5
million. We recorded an intangible asset for $20.2 million (see Note 5). In conjunction with this transaction, we terminated our existing license agreement
with Maxygen including terminating our obligation to pay biofuels royalties to Maxygen.

During the year ended December 31, 2010, Maxygen provided to Codexis certain legal and administrative services, with total fees owed to Maxygen of
$170,000. We had no amounts owed to Maxygen in connection with such services at December 31, 2012 and 2011, respectively.

In August 2006, we had entered into an amendment to the license agreement with Maxygen. Under the amendment, we were required to pay Maxygen a fee
based on a percentage of all consideration we receive from third parties related to the use of certain intellectual property owned or controlled by Maxygen in
the specified field of biofuels. We expensed all payments owed to Maxygen as they became due as collaborative research and development expenses, which
we reported as research and development expenses in our consolidated statements of operations. We were also obligated to reimburse up to 20% of the costs
incurred by Maxygen related to the prosecution and maintenance of the patents licensed from Maxygen relating to our core technology. We paid Maxygen a
fee based on our collaborative research and development agreement with Shell (see Note 3). We expensed $1.2 million during the year ended December 31,
2010. No amounts were payable to Maxygen at December 31, 2012 or 2011, respectively.

Shell and Raízen

Prior to June 2011 Shell was considered a related party due to the size of its ownership interest. As discussed in Note 3, “Collaborative Research and
Development Agreements,” Shell transferred full ownership of our common stock to Raízen, Shell’s joint venture with Cosan in Brazil. Based on our analysis
and effective as of July 1, 2011, Shell was no longer considered a related party. Before June 30, 2011, related party receivables, related party deferred
revenue, and related party collaboration research and development revenue were primarily comprised of transactions under our five-year Shell Research
Agreement (replaced by the New Shell Agreement effective as of August 31, 2012) and the Shell License Agreement. The revenues earned from Shell are
included in the collaborative research and development line on our consolidated statement of operations. Collaborative research and development revenue
received from Shell accounted for 51%, 51% and 62% of our revenues for the years ended December 31, 2012, 2011 and 2010, respectively.

At the time of the transfer, Raízen owned 5.6 million shares of our common stock and has the right to appoint a member to our board of directors. In
September 2011, we entered into a joint development agreement with Raízen to develop an improved first generation ethanol process with enhanced
economics. There has been no material financial activity with Raízen through December 31, 2012 and work under this joint development agreement has been
completed and we do not expect this project to continue.

Raízen has exclusive rights to market and use CodeXyme® in Brazil. We are engaged in discussions with Raízen about obtaining rights to market CodeXyme®
to all ethanol producers in Brazil. Although we do not expect to receive development funding from Raízen for CodeXyme®, Raízen will remain a target
customer for CodeXyme® should Raízen decide to build capacity for second generation ethanol in Brazil.

Exela PharmaSci, Inc.

We signed a license agreement with Exela PharmaSci, Inc. (“Exela”) in 2007. A member of our board of directors is also on the board of directors of Exela.
Under the terms of the agreement, Exela would pay us a royalty based on their achievement of certain commercial goals.

During the years ended December 31, 2012, and 2011, we recognized $150,000 and $450,000 of revenue, respectively, related to this arrangement, shown in
our consolidated statement of operations as collaborative research and development revenue. We did not recognize any revenue from Exela prior to 2011. As
of December 31, 2012 and 2011, we had no amounts owed from Exela.

8. Commitments and Contingencies

Operating Leases

Our headquarters are located in Redwood City, California where we occupy approximately 107,000 square feet of office and laboratory space in four
buildings. On March 16, 2011, we entered into a Fifth Amendment to Lease (the “Fifth Amendment”) with Metropolitan Life Insurance Company
(“MetLife”) with respect to our offices located at 200 and 220 Penobscot Drive, Redwood City, California, (the “Penobscot Space”), 400 Penobscot Drive,
Redwood City, California (the “Building 2 Space”) and 640 Galveston Drive, Redwood City, California (the “Galveston Space”), and with respect to
approximately 29,921 square feet of additional space located at 101 Saginaw Drive, Redwood City, California (the “Saginaw Space”). Under the Fifth
Amendment, the term of the lease of the Penobscot Space, the Building 2 Space and the Saginaw Space lasts until January 31, 2020, and we have options to
extend for two additional five year periods. Pursuant to the Fifth Amendment, we surrendered the Galveston Space in August 2011. The Fifth Amendment
provided a number of incentives to us including forgiveness of rent payments for the initial two months of the lease term, a tenant improvement allowance
(“TIA”) of $2.4 million and an additional $0.8 million special allowances for certain HVAC costs. We applied the TIA funds toward capital improvements to
the expanded facility as well as upgrades and reconfiguration of existing lab and office space.

As of December 31, 2012, we incurred $3.6 million of capital improvement costs related to the facilities. During 2011, we requested and received $1.8
million of reimbursements from the landlord out of the TIA for the completed construction. We requested and received reimbursement of the remaining $1.3
million of TIA and special HVAC allowance during the second quarter of 2012. The TIA is recorded once cash is received and is amortized on a straight line
basis over the term of the lease as a reduction in rent expense.

We also lease space in the 501 Chesapeake Drive, Redwood City, California (the “501 Chesapeake Space”). The lease for the 501 Chesapeake Space was not
extended with the Fifth Amendment. In September 2012, we entered into a Sixth Amendment to Lease (the “Sixth Amendment”) with MetLife with respect to
the Company’s offices located at 501 Chesapeake Drive. The Sixth Amendment extends the term of the lease of the 501 Chesapeake Space, which would
have otherwise expired in January 2013, to January 31, 2017. Pursuant to the Sixth Amendment, we have two consecutive options to extend the term of the
lease for the 501 Chesapeake Space for an additional period of five years per option.

As part of the Q3 2012 Restructuring Plan, we are in the process of vacating the Saginaw Space and we have begun marketing the facility for sublease (see
Note 14).

Rent expense is recognized on a straight-line basis over the term of the lease. In accordance with the terms of the amended lease agreement, we exercised our
right to deliver a letter of credit in lieu of a security deposit. The letters of credit in the amount of $707,000 as of December 31, 2012 and 2011 are
collateralized by a deposit balances held by the bank. These deposits are recorded as restricted cash on the consolidated balance sheets.

We also rent facilities in Hungary. Rent expense is being recognized on a straight-line basis over the respective terms of these leases. Our leased facility in
Singapore has been vacated and we recorded a cease use liability of $354,000 representing the remaining six months lease term for the facility as an accrued
expense at December 31, 2012.

As of December 31, 2012 and 2011 we had asset retirement obligations of $109,000 and $579,000, respectively from operating leases, whereby we must
restore the facilities that we are renting to their original form. We incurred $30,000 and $39,000 of accretion expense related to our asset retirement
obligations in 2012 and 2011, respectively. We are expensing the asset retirement obligation over the terms of the respective leases. We review the estimated
obligation each period and we make adjustments if our estimates change.

We have been subject to various legal proceedings related to matters that have arisen during the ordinary course of business. Although there can be no
assurance as to the ultimate disposition of these matters, we have determined, based upon the information available, that the expected outcome of these
matters, individually or in the aggregate, will not have a material adverse effect on our consolidated financial position, results of operations or cash flows.

Indemnifications

We are required to recognize a liability for the fair value of any obligations we assume upon the issuance of a guarantee. We have certain agreements with
licensors, licensees and collaborators that contain indemnification provisions. In such provisions, we typically agree to indemnify the licensor, licensee and
collaborator against certain types of third party claims. The maximum amount of the indemnifications is not limited. We accrue for known indemnification
issues when a loss is probable and can be reasonably estimated. There were no accruals for expenses related to indemnification issues for any periods
presented.

Other contingencies

In November 2009, one of our foreign subsidiaries sold intellectual property to us. Under the local laws, the sale of intellectual property to a nonresident legal
entity is deemed an export and is not subject to value added tax. However, there is uncertainty regarding whether the items sold represented intellectual
property or research and development services, which would subject the sale to value added tax. We believe that the uncertainty results in an exposure to pay
value added tax that is more than remote but less than likely to occur and, accordingly, have not recorded an accrual for this exposure. Should the sale be
deemed a sale of research and development services, we could be obligated to pay an estimated amount of $0.6 million.

9. Warrants

Our outstanding warrants are exercisable for common stock at any time during their respective terms. During the year ended December 31, 2012, 6,066
warrants were exercised in a net share transaction to acquire 3,308 shares of our common stock. No warrants were exercised during 2011.

At December 31, 2012, the following warrants were issued and outstanding:

In 2002, we adopted the 2002 Stock Plan (the “2002 Plan”), pursuant to which our board of directors issued incentive stock options, non-statutory stock
options (options that do not qualify as incentive stock options) and restricted stock to our employees, officers, directors or consultants. In March 2010, our
board of directors and stockholders approved the 2010 Equity Incentive Award Plan (the “2010 Plan”), which became effective upon the completion of our
IPO in April 2010. A total of 1,100,000 shares of common stock were initially reserved for future issuance under the 2010 Plan and any shares of common

stock reserved for future grant or issuance under our 2002 Plan that remained unissued at the time of completion of the IPO became available for future grant
or issuance under the 2010 Plan. In addition, the shares reserved for issuance pursuant to the exercise of any outstanding awards under the 2002 Plan that
expire unexercised will also become available for future issuance under the 2010 Plan. The 2010 Plan also provides for automatic annual increases in the
number of shares reserved for future issuance, and during the year ended December 31, 2012 an additional 1,439,827 shares were reserved under the 2010
plan as a result of this provision. As of December 31, 2012, we had a total of 10,857,842 shares of common stock reserved for issuance under our Plans and
no shares available for issuance under the 2002 Plan.

Options granted under the 2002 Plan and 2010 Plan expire no later than 10 years from the date of grant. For incentive stock options and nonstatutory stock
options, the option price shall be at least 100% and 85%, respectively, of the fair value of the common stock on the date of grant, as determined by the board
of directors. If, at the time of a grant, the optionee directly or by attribution owns stock possessing more than 10% of the total combined voting power of all of
our outstanding capital stock, the exercise price for these options must be at least 110% of the fair value of the underlying common stock. Options typically
vest over a four-year period at a rate of no less than 25% per year but may be granted with different vesting terms.

In June 2012, we granted 400,000 options and 750,000 restricted stock awards pursuant to the employment agreement with our new chief executive officer,
Mr. John Nicols. The option award has a per share exercise price equal to $3.46 per share, which was the closing price of the Company’s common stock on
June 13, 2012. Mr. Nicols will vest 25% of the option award on June 13, 2013 with the remaining shares vesting ratably on a monthly basis over a period of
36 months thereafter, such that the option award would be fully vested and exercisable on June 13, 2016. The restricted stock award of 750,000 shares vest
over four years with 25% of the awards vesting on each annual anniversary such that the restricted stock award would be fully vested on June 13, 2016.

In September 2012, we granted 200,000 options and 50,000 restricted stock awards pursuant to the offer letter agreement with our new chief financial officer,
Mr. David O’Toole. The option award has a per share exercise price equal to $2.72 per share, which was the closing price of the Company’s common stock on
September 10, 2012. Mr. O’Toole will vest 25% of the option award on September 4, 2013 with the remaining shares vesting ratably on a monthly basis over
a period of 36 months thereafter, such that the option award would be fully vested and exercisable on September 4, 2016. The restricted stock award of 50,000
shares vest over four years with 25% of the awards vesting on each annual anniversary of Mr. O’Toole’s start date such that the restricted stock award would
be fully vested on September 4, 2016.

We granted 1,147,953 restricted stock units (“RSU”) during the year ended December 31, 2012. The RSUs vest over four years with 25% of the RSUs vesting
annually. The fair value of the RSUs was calculated based on the NASDAQ quoted stock price on the date of the grant with the expense recognized over the
vesting period. For the year ended December 31, 2012, we recorded $1.8 million of stock compensation expense related to the RSUs. During the year,
167,401 and 568,960 RSUs were released and cancelled, respectively. At December 31, 2012, there were 957,811 outstanding RSUs with an average
remaining life of 2.18 years, a weighted average grant price of $3.54 and an unamortized expense of $5.4 million.

The weighted-average grant date fair value of options granted during the years ended December 31, 2012, 2011 and 2010 was $1.91, $5.19, and $7.06,
respectively.

The aggregate intrinsic value of exercised stock options was $0.9 million, $9.0 million, and $6.6 million during the years ended December 31, 2012, 2011,
and 2010, respectively. The intrinsic value of stock options outstanding, exercised, exercisable and expected-to-vest is calculated based on the difference
between the exercise price and the fair value of our common stock.

Stock-based compensation costs capitalized during the years ended December 31, 2012, 2011, and 2010 were insignificant. There were no stock-based
compensation tax benefits during the years ended December 31, 2012, 2011, and 2010.

At December 31, 2012, there was $9.4 million of unrecognized stock-based compensation cost which is expected to be recognized over an average period of
1.87 years.

Stockholder Rights Plan

In August 2012, our board of directors adopted a stockholder rights plan and declared a dividend of one preferred share purchase right for each share of our
common stock held by stockholders of record as of September 18, 2012. Each right entitles stockholders, after the rights become exercisable, to purchase one
one-thousandth of a share of our Series A Junior Participating Preferred Stock, par value $0.0001, at a purchase price of $11.35 per one-thousandth of a share
of Series A Junior Participating Preferred Stock. In general, the rights become exercisable when a person or group acquires 15% or more of our common
stock or a tender offer for 15% or more of our common stock is announced or commenced. The rights may discourage a third-party from making an
unsolicited proposal to acquire us as exercise of the rights would cause substantial dilution to a person or group that attempts to acquire us on terms not
approved by our board of directors. The rights should not interfere with any merger or other business combination approved by our board of directors since
the rights may be redeemed by us at $0.0001 per right at any time before any person or group acquire 15% or more of our outstanding common stock. These
rights expire in September 2013.

Stock-Based Compensation Expense

We estimate the fair value of stock-based awards granted to employees and directors using the Black- Scholes option-pricing model. The Black-Scholes
option-pricing model requires the use of highly subjective and complex assumptions to determine the fair value of stock-based awards, including the expected
life of the option and expected volatility of the underlying stock over the expected life of the related grants. Since we were not a publicly traded entity prior to
April 2010, sufficient company-specific historical volatility data was not available for reporting periods prior to the second quarter of 2012. As a result, for
those periods, we estimated the expected volatility based on the historical volatility of a group of unrelated public companies within our industry. Effective for
the second quarter of 2012, we determined we had sufficient company-specific historical volatility data. As a result, we estimate the expected volatility based
on historical volatility of our common stock.

Due to our limited history of grant activity, the expected life of options granted to employees is calculated using the “simplified method” permitted by the
SEC as the average of the total contractual term of the option and its vesting period. The risk-free rate assumption was based on United States Treasury
instruments whose terms were consistent with the terms of our stock options. The expected dividend assumption was based on our history and expectation of
dividend payouts.

The following assumptions were used to estimate the fair value of our employee option grants: 

Weighted-average expected life (years)

Weighted-average risk free interest rate

During the years ended December 31, 2012 and 2011, we did not grant any options to purchase shares of common stock to non-employees. In 2010, we
granted options to purchase 20,000 shares of common stock to non-employees which were subsequently canceled prior to any vesting of the option grant.

Stock-based compensation expense attributable to cost of goods sold was immaterial.

During the second quarter of 2012, certain members of our management team were informed that their annual bonus for 2012 would be paid only in the form
of common stock awards rather than cash payments. In January 2013, the Company decided to pay out the bonus in cash instead. As a result, we reversed the
bonus accrual amount that we previously recorded in stock-based compensation expense and additional paid in capital and accrued a liability for the expected
cash payout. We expect to pay the 2012 annual bonus in the second quarter of 2013.

Redeemable Convertible Preferred Stock

On April 27, 2010, we completed our initial public offering of common stock (“IPO”) selling 6,000,000 shares at an offering price of $13.00 per share,
resulting in net proceeds of approximately $67.7 million, after deducting underwriting discounts, commissions and other related transaction costs.

Upon the closing of the IPO, our then outstanding shares of redeemable convertible preferred stock were automatically converted into 25,307,446 shares of
common stock and the related redeemable convertible preferred stock was reclassified to common stock and additional paid-in capital, our outstanding
preferred stock warrants were automatically converted into common warrants to purchase a total of 288,438 shares of common stock and the related
redeemable convertible preferred stock warrant liability was reclassified to additional paid-in capital.

Deferred income taxes reflect the net tax effects of (a) temporary differences between the carrying amounts of assets and liabilities for financial reporting
purposes and the amounts used for income tax purposes, and (b) operating losses and tax credit carryforwards.

The tax benefit of NOL, temporary differences and credit carryforwards are recorded as an asset to the extent that management assesses that realization is
“more likely than not.” Realization of the future tax benefits is dependent on our ability to generate sufficient taxable income within the carryforward period.
Because of our history of operating losses, management believes that recognition of the deferred tax assets arising from the above-mentioned future tax
benefits is currently not more likely than not to be realized and, accordingly, has provided a valuation allowance. Accordingly, the net deferred tax assets in
the United States, Hungary and Singapore have been fully reserved by a valuation allowance. The net valuation allowance increased by $8.6 million, $5.8
million and $1.6 million during the years ended December 31, 2012, 2011 and 2010, respectively. At such time as it is determined that it is more likely than
not that the deferred tax assets are realizable, the valuation allowance will be reduced.

The following table sets forth our federal, state and foreign NOL carryforwards and federal research and development tax credits as of December 31, 2012 (in

On January 2, 2013, the President signed into law The American Taxpayer Relief Act of 2012. Under prior law, a taxpayer was entitled to a research tax credit
for qualifying amounts paid or incurred on or before December 31, 2011. The 2012 Taxpayer Relief Act extends the research credit for two years to
December 31, 2013. The extension of the research credit is retroactive and includes amounts paid or incurred after December 31, 2011. As a result of the
retroactive extension, we expect to recognize a deferred tax asset of approximately $0.4 million for qualifying amounts incurred in 2012 which will be fully
offset by a valuation allowance. The deferred tax asset and corresponding valuation allowance will be recognized in the period of enactment, which is the first
quarter of 2013.

Current federal and California tax laws include substantial restrictions on the utilization of NOLs and tax credit carryforwards in the event of an ownership
change of a corporation. Accordingly, our ability to utilize NOLs and tax credit carryforwards may be limited as a result of such ownership changes. Such a
limitation could result in the expiration of carryforwards before they are utilized.

Income tax expense or benefit from continuing operations is generally determined without regard to other categories of earnings, such as discontinued
operations and other comprehensive income. An exception is provided in ASC Topic 740, Income Taxes, when there is aggregate income from categories
other than continuing operations and a loss from continuing operations in the current year. In this case, the tax benefit allocated to continuing operations is the
amount by which the loss from continuing operations reduces the tax expenses recorded with respect to the other categories of earnings, even when a
valuation allowance has been established against the deferred tax assets. In instances where a valuation allowance is established against current year losses,
income from other sources, including gain from available-for-sale securities recorded as a component of other comprehensive income, is considered when
determining whether sufficient future taxable income exists to realize the deferred tax assets. As a result, for the year ended December 31, 2012, the Company
recorded a tax expense of $69,000 in other comprehensive income related to the gain on available-for-sale securities, and recorded a corresponding tax benefit
of $69,000 in continuing operations.

The Company has not provided for United States federal and state income taxes on all of the non-United States subsidiaries’ undistributed earnings as of
December 31, 2012, because such earnings are intended to be indefinitely reinvested. As of December 31, 2012, cumulative un-remitted foreign earnings that
are considered to be permanently invested outside the United States and on which no United States taxes have been provided were approximately $1.0
million. The residual United States tax liability, if such amounts were remitted, would be nominal.

A reconciliation of the beginning and ending amount of unrecognized tax benefits is as follows (in thousands):

We recognize interest and penalties in income tax expense. Total interest and penalties recognized in the consolidated statement of operations was $11,000,
$39,000 and $75,000 respectively in 2012, 2011 and 2010. Total penalties and interest recognized in the balance sheet was $250,000 and $239,000
respectively in 2012 and 2011. The total unrecognized tax benefits that, if recognized currently, would impact our effective tax rate were $1.5 million and
$1.4 million as of December 31, 2012 and

Table of Contents

2011, respectively. We expect $54,000 of unrecognized tax benefits to be recognized within the next 12 months. We are not subject to examination by United
States federal or state tax authorities for years prior to 2002 and foreign tax authorities for years prior to 2006.

12. 401(k) Plan

In January 2005, we implemented a 401(k) Plan covering certain employees. Currently, all of our United States based employees over the age of 18 are
eligible to participate in the 401(k) Plan. Under the 401(k) Plan, eligible employees may elect to reduce their current compensation up to a certain annual limit
and contribute these amounts to the 401(k) Plan. We may make matching or other contributions to the 401(k) Plan on behalf of eligible employees. In the
years ended December 31, 2012, 2011 and 2010, we did not make any contributions to the 401(k) Plan on behalf of eligible employees.

13. Segment Reporting

Operating segments are defined as components of an enterprise about which separate financial information is available that is evaluated regularly by the chief
operating decision maker, or decision making group, in deciding how to allocate resources and in assessing performance. Our chief operating decision maker
is our Chief Executive Officer and our board of directors. The Chief Executive Officer and our board of directors review financial information presented on a
consolidated basis, accompanied by information about revenues by geographic region, for purposes of allocating resources and evaluating financial
performance. We have one business activity and there are no segment managers who are held accountable for operations, operating results beyond revenue
goals or plans for levels or components below the consolidated unit level. Accordingly, we have a single reporting segment. Operations outside of the United
States consist principally of research and development and sales activities.

14. Restructuring

As a result of the termination of the Shell Research Agreement, we initiated a series of cost reduction measures. During the third quarter of 2012, our board of
directors approved and committed to a restructuring plan (the “Q3 2012 Restructuring Plan”) to reduce our cost structure which included approximately 173
employee terminations in the United States and Singapore and the closing of our Singapore facility. Approximately 150 of the total 173 employee
terminations impacted the research and development functions with remaining 23 employees impacting the general and administrative functions.

Our cost of the Q3 2012 Restructuring Plan was $2.4 million, comprised of $1.1 million of leasehold improvement write down, $0.7 million for employee
severance and other termination benefits, $0.3 million for facility lease termination costs and $0.3 million for equipment disposal charges. As of December
31, 2012, planned costs of $1.5 million have been recognized in selling, general and administrative expenses and $0.9 million have been recognized in
research and development on our consolidated statements of operations. We have made cash payments of $0.6 million as of December 31, 2012, with $68,000
recorded in accrued compensation and $0.4 million recorded as accrued expenses on our consolidated balance sheet as of December 31, 2012. We anticipate
recording no further costs under this restructuring plan. We anticipate the remaining costs under the Q3 2012 Restructuring Plan will be paid by the end of the
first half of 2013.

During the first quarter of 2012, our board of directors approved and committed to a restructuring plan (the “Q1 2012 Restructuring Plan”) to reduce our cost
structure, which included a total of 13 employee terminations in Hungary, Singapore, and the United States. The total planned cost of the Q1 2012
Restructuring Plan was $567,000, comprised of employee severance and other termination benefits. As of December 31, 2012, actual costs of $572,000 have
been recognized in selling, general and administrative expenses on our consolidated statements of operations. We have made cash payments of $512,000 and
recorded $60,000 of reductions to previously recorded charges and have no further obligations under this restructuring plan. We do not anticipate recording
any further charges under this restructuring plan.

ITEM 9. CHANGES IN AND DISAGREEMENTS WITH ACCOUNTANTS ON ACCOUNTING AND FINANCIAL DISCLOSURES

None.

Evaluation of Disclosure Controls and Procedures

ITEM 9A. CONTROLS AND PROCEDURES

Our management, under the supervision of our Chief Executive Officer and Chief Financial Officer and with the participation of our disclosure committee,
evaluated the effectiveness of the design and operation of our disclosure controls and procedures as of December 31, 2012. The term “disclosure controls and
procedures,” as defined in Rules 13a-15(e) and 15d-15(e) under the Exchange Act, means controls and other procedures of a company that are designed to
ensure that information required to be disclosed by us in the reports that we file or submit under the Exchange Act is recorded, processed, summarized and
reported within the time periods specified in the SEC's rules and forms. Disclosure controls and procedures include, without limitation, controls and
procedures designed to ensure that information required to be disclosed by us in the reports that we file or submit under the Exchange Act is accumulated and
communicated to our management, including our Chief Executive Officer and Chief Financial Officer, as appropriate, to allow timely decisions regarding
required disclosure. Based on this evaluation, our Chief Executive Officer and Chief Financial Officer concluded that our disclosure controls and procedures
were not effective as of December 31, 2012 at the reasonable assurance level due to the material weakness described below under “Management's Report on
Internal Control over Financial Reporting.” Notwithstanding the existence of the material weakness, management has concluded that the consolidated
financial statements included in this report present fairly, in all material respects, our consolidated financial position, results of operations and cash flows for
the periods presented in conformity with United States generally accepted accounting principles.

Management’s Report on Internal Control over Financial Reporting

Our management is responsible for establishing and maintaining adequate internal control over financial reporting, as such term is defined in Exchange Act
Rules 13a-15(f) and 15d-15(f). Internal control over financial reporting is a process designed to provide reasonable assurance regarding the reliability of
financial reporting and the preparation of financial statements for external reporting purposes in accordance with United States generally accepted accounting
principles.

Under the supervision and with the participation of our management, including our Chief Executive Officer and Chief Financial Officer, we conducted an
evaluation of the effectiveness of our internal control over financial reporting as of December 31, 2012 based on the guidelines established in Internal
Control-Integrated Framework issued by the Committee of Sponsoring Organizations of the Treadway Commission (COSO).

In connection with the integrated audit of our consolidated financial statements and internal control over financial reporting and management's assessment of
our internal controls over financial reporting at December 31, 2012, a material weakness in our internal control over financial reporting was identified. The
material weakness we identified relates to the lack of a sufficient number of qualified personnel to timely and appropriately account for complex, non-routine
transactions in accordance with United States generally accepted accounting principles. Examples of these significant non-routine transactions include, but
are not limited to, complicated revenue recognition transactions and complex contractual arrangements. The material weakness resulted in the recording of
audit adjustments for the period ended December 31, 2012.

A material weakness is defined as a deficiency, or combination of deficiencies, in internal control over financial reporting such that there is a reasonable
possibility that a material misstatement of annual or interim consolidated financial statements will not be prevented or detected on a timely basis.

As a result of the material weakness described above, we have concluded our internal control over financial reporting was not effective at December 31, 2012.
Management reviewed the results of our annual assessment with our Audit Committee.

Our internal control over financial reporting as of December 31, 2012 has been audited by Ernst & Young LLP, an independent registered public accounting
firm, as stated in their report which is included in Part II, Item 8 of this Annual Report.

Management's Remediation Activities

With the oversight of senior management and our audit committee, we plan to take steps intended to address the underlying causes of the material weakness
in the immediate future, primarily through the hiring of accounting and finance personnel with technical accounting and financial reporting experience, and
the implementation and validation of improved accounting and financial reporting procedures.

101

Table of Contents

We have not yet been able to remediate this material weakness. We do not know the specific timeframe needed to remediate all of the control deficiencies
underlying this material weakness. In addition, we may need to incur incremental costs associated with this remediation, primarily due to the hiring of finance
and accounting personnel, and the implementation and validation of improved accounting and financial reporting procedures. As we continue to evaluate and
work to improve its internal control over financial reporting, we may determine to take additional measures to address the material weakness.

Changes in Internal Control over Financial Reporting

Other than the changes described above under “Management's Report on Internal Control over Financial Reporting,” there were no changes in our internal
control over financial reporting identified in connection with the evaluation required by paragraph (d) of Exchange Act Rules 13a-15 or 15d-15 that occurred
during our last fiscal quarter that have materially affected, or are reasonably likely to materially affect, our internal control over financial reporting.

Inherent Limitations on Effectiveness of Controls

In designing and evaluating the disclosure controls and procedures, management recognizes that any controls and procedures, even if determined effective
and no matter how well designed and operated, can provide only reasonable assurance of achieving the desired control objectives to prevent or detect
misstatements. In addition, the design of disclosure controls and procedures must reflect the fact that there are resource constraints and that management is
required to apply judgment in evaluating the benefits of possible controls and procedures relative to their costs. Also, projections of any evaluation of
effectiveness to future periods are subject to the risk that controls may become inadequate because of changes in conditions, or that the degree of compliance
with the policies or procedures may deteriorate.

Requirement  Forecast  or  Purchase  Order,  the  terms  of  this  Agreement  shall  govern  unless  otherwise  agreed  to  in  writing  by  the
Parties.  For  clarity,  no  term  or  condition  added  by  Arch  to  a  Purchase  Order  shall  be  binding  on  Codexis  unless  such  term  or
condition is specifically agreed to by Codexis in writing signed by a duly authorized officer of Codexis.

2.10    Delivery and Storage of Codexis Enzymes. Subject to Section 2.7, Codexis shall deliver to Arch the amount of each
of the Codexis Enzyme(s) specified in each Purchase Order no later than the dates specified therein; provided, that Codexis shall
not be required to deliver such amount prior to three (3) months after receiving such Purchase Order. All Codexis Enzyme shall be
shipped by Codexis FCA Origin (Incoterms 2010) at Codexis’ manufacturer’s facility, and risk of loss shall pass to Arch upon such
delivery.  Codexis  shall  ship  Codexis  Enzymes  under  appropriate  packaging  and  storage  conditions.  Codexis  shall  provide  any
documentation  required  for  shipment  of  Supplied  Enzymes.  Arch  agrees  to  store  all  Codexis  Enzymes  in  accordance  with  the
storage requirements provided by Codexis to and Arch shall bear any and all costs arising from failure to comply with such storage
requirements, including without limitation, any payments required for additional quantities of Codexis Enzymes purchased by Arch
due to such failure.

2.11    Inspection of Codexis Enzyme. Codexis Enzymes shall be shipped with a mandatory certificate of analysis as per
customary industry practice. Arch shall have ten (10) days to inspect each shipment and provide a written rejection of any shipment
of Codexis Enzyme on the basis that such Codexis Enzyme does not comply with the applicable Enzyme Specification. In the event
that Codexis receives a written notice of rejection from Arch, subject to Section 2.13, Codexis shall replace such rejected Codexis
Enzyme  pursuant  to  Section  2.12.  If  Arch  fails  to  notify  Codexis  in  writing  of  a  rejection  within  such  ten  (10)  day  period,  the
shipment of Codexis Enzyme shall be deemed accepted by Arch and Codexis shall have no obligation to accept a return of or to
replace such shipment. In any event, Arch shall pay for such Codexis Enzymes as otherwise provided herein and shall be entitled
to, at its sole discretion, a credit or refund of the properly rejected shipment at the time they are ultimately rejected.

2.12    Replacement of Defective Codexis Enzyme. In the event that Codexis receives a written notice of rejection from

of such rejected Codexis Enzyme, including without limitation disposal of such rejected Codexis Enzyme, within sixty (60) days
after receiving Arch’s written notice of rejection. For clarity, the foregoing right shall not limit any other remedy available at law or
in equity. Arch shall keep such defective Codexis Enzyme at its premises until receipt of Codexis’ instruction for Arch to return or
otherwise dispose of such defective Codexis Enzyme. Notwithstanding anything to the contrary, Codexis shall have no obligation
to  replace  any  shipment  of  Codexis  Enzyme  or  part  thereof  pursuant  to  this  Section  2.12  or  issue  a  refund  or  credit  pursuant  to
Section 2.11 in the event Codexis can establish that there was

[***] Certain information in this document has been omitted and filed separately with the Securities and Exchange
Commission. Confidential treatment has been requested with respect to the omitted portions.

no defect or such defect occurred after delivery of such shipment of Codexis Enzyme. Codexis shall in good faith provide details to
Arch of test methods  that  are  customarily  employed  by  Codexis  to  check  the  purity and quality of Codexis Enzyme supplied to
Arch. In the case of a marginal Enzyme Specification failure or non-compliance, the relevant Codexis Enzyme can be offered to
Arch for use at a higher loading rate in the production process than dictated by the standard recipe. Under such cases, if there is
increased inconvenience to Arch in use of such Codexis Enzyme then a reduced price will be agreed to by the Parties that reflects
the increased usage and inconvenience.

2.13    Disputes. If Codexis disputes Arch’s right to reject all or part of any shipment of any Codexis Enzyme as set forth in
Section 2.11, Codexis shall notify Arch within ten (10) days after receipt of Arch’s written notice of such rejection. Such dispute
shall  be  resolved  by  a  Third  Party  within  thirty  (30)  days  of  such  notice.  Such  Third  Party  shall  have  expertise  in  the  area  of
biocatalysis,  the  identity  of  whom  shall  be  mutually  agreed  upon  by  the  Parties,  and  the  appointment  of  whom  shall  not  be
unreasonably  delayed  or  conditioned  by  either  Party.  The  determination  of  such  Third  Party  with  respect  to  all  or  part  of  any
shipment of any Codexis Enzyme shall be final and binding upon the Parties. The Third Party’s scope of review and decision shall
be strictly limited to the reasons given by Arch in rejecting the shipment or part thereof, and such Third Party may not consider any
alleged defects or reasons beyond the alleged defects and reasons given by Arch. For the avoidance of doubt, if such Third Party
determines that the reasons given by Arch in rejecting the shipment or part thereof were not proper, then no refund or credit shall be
due to Arch under Section 2.11, even if such Third Party determines that the shipment was defective on other, independent bases.
The fees and expenses of such Third Party shall be paid by the Party against which the determination is made. Notwithstanding
anything  to  the  contrary  in  this  Article  2,  Codexis  shall  continue  delivering  Codexis  Enzyme(s)  pursuant  to  the  terms  of  this
Agreement and Arch shall pay for Codexis Enzymes, including without limitation replacement of any defective Codexis Enzyme,
pursuant to the terms of this Agreement during the dispute resolution process set forth in this Section 2.13.

technology  relating  to  the  Codexis  Process,  including  without  limitation  the  Codexis  IP  Rights,  in  violation  of  the  terms  and
conditions of this Agreement; or (ii) reverse engineered or created any derivatives of, or made modifications and/or improvements
to  the  Codexis  Enzyme  or  any  DNA  encoding  it  (the  “Codexis  Enzyme-Related  Restrictions”).  Such  records  and  books  of
accounting shall be  kept  at  Arch’s  principal  place  of  business. Such  audit  shall  take  place  no  more  than  once  every  twelve  (12)
months  during  regular  business  hours,  and  upon  not  less  than  ten  (10)  days’  written  notice.  Such  independent  auditor  shall  be
subject to confidentiality obligations, and such auditor shall not disclose Confidential Information of Arch to Codexis except to the
extent such Confidential Information is related to the subject matter of such

10.    CONFIDENTIALITY

10.1    In General. In connection with this Agreement each Party (the “Disclosing Party”) may provide to the other Party

(the “Receiving Party”), Confidential Information.

10.2    Non-Disclosure and Non-Use. The Receiving Party shall maintain the Confidential Information of the Disclosing
Party  in  confidence,  shall  not  disclose  such  Confidential  Information  to  any  Third  Party,  and  shall  not  use  such  Confidential
Information for any purpose except as expressly permitted under the terms and conditions of this Agreement. Notwithstanding the
previous  sentence,  the  Receiving  Party  may  disclose  the  Confidential  Information  of  the  Disclosing  Party  solely  on  a  “need  to
know  basis”  to  its  Affiliates  and  its  officers,  directors,  employees,  legal  counsel,  contractors  and  agents,  and  independent  legal
counsel, each of whom prior to disclosure must be bound by obligations of nondisclosure and non-use no less restrictive than the
obligations set forth in this Article 10; provided, however, that, in each of the above situations, the Receiving Party shall remain
responsible for any failure by any person or entity who receives Confidential Information pursuant to this Section 10.2 to treat such
Confidential  Information  as  required  under  this  Article  10.  The  Receiving  Party  shall  take  the  same  degree  of  care  that  the
Receiving Party uses to protect its own confidential and proprietary information of a similar nature and importance, but in no event
shall such care be less than reasonable care.

10.3        Exceptions.  The  obligations  of  non-disclosure  and  non-use  under  Section  10.2  will  not  apply  as  to  particular
Confidential  Information  of  a  Disclosing  Party  to  the  extent  that  such  Confidential  Information:  (a)  is  at  the  time  of  receipt,  or
thereafter becomes, through no fault of the Receiving Party or its Affiliates, published or publicly known or available; (b) is known
by the Receiving Party or its Affiliates at the time of receiving such information, as evidenced by competent written records; (c) is
hereafter furnished to the Receiving Party or its Affiliates by a Third Party without breach of a duty to the Disclosing Party; or (d)
is  independently  discovered  or  developed  by  the  Receiving  Party  or  its  Affiliates  without  use  of,  application  of,  access  to,  or
reference to Confidential Information of the Disclosing Party, as evidenced by competent written records.

10.4    Disclosure Required by Law. Disclosure of Confidential Information shall not be precluded if such disclosure (a) is

in response to a valid order, or required under the regulations, of

[***] Certain information in this document has been omitted and filed separately with the Securities and Exchange
Commission. Confidential treatment has been requested with respect to the omitted portions.

a court or other governmental body; or (b) is required by Applicable Law; provided, however,  that  the  Receiving  Party  first  has
given reasonable prior notice to the Disclosing Party and at the Disclosing Party’s request, the Receiving Party cooperates with the
Disclosing Party’s efforts, as applicable, to obtain a protective order limiting the extent of such disclosure and requiring that the
Confidential  Information  so  disclosed  be  used  only  for  the  purposes  for  which  such  order  was  issued  or  as  required  by  such
Applicable Law.

10.5        Remedies.  The  Receiving  Party  agrees  that  its  obligations  under  this  Article  10  are  necessary  and  reasonable  to
protect  the  Disclosing  Party’s  business  interests  and  that  the  unauthorized  disclosure  or  use  of  Confidential  Information  of  the
Disclosing Party will cause irreparable harm and significant injury, the degree of which may be difficult to ascertain. The Receiving
Party further acknowledges and agrees that in the event of any actual or threatened breach of this Article 10, the Disclosing Party
may  have  no  adequate  remedy  at  law  and,  accordingly,  that  the  Disclosing  Party  will  have  the  right  to  seek  an  immediate
injunction, without an obligation to post a bond or any similar security, enjoining any breach or threatened breach of this Article 10,
as  well  as  the  right  to  pursue  any  and  all  other  rights  and  remedies  available  at  law  or  in  equity  for  such  breach  or  threatened
breach.

10.6        Agreement  Terms.  The  existence  of,  and  the  terms  and  conditions  of,  this  Agreement  shall  be  Confidential
Information of each of the Parties, and subject to the terms of this Article 10; provided, however, that (x) each Party may disclose
this  Agreement,  in  confidence,  (i)  to  legal,  scientific  and  financial  advisors  and  (ii)  in  connection  with  any  proposed  legal
transaction involving the disclosing Party in the form of mergers, offerings, acquisitions, fundings and investments; and (y) each
Party may disclose this Agreement, in its entirety or with portions redacted, as may be required by Applicable Law, including but
not limited to filing of this Agreement with the Securities and Exchange Commission (and, for the avoidance of doubt, if any such
disclosure or filing is made on a non-confidential basis then the portions disclosed or filed shall no longer be deemed Confidential
Information).

10.7    Survival. All obligations of non-disclosure and non-use imposed pursuant to the terms and conditions of this Article
10 shall survive expiration or termination of this Agreement and continue in full force and effect for a period of ten (10) years after
the effective date of such expiration or such termination.

and/or  a  Third  Party,  during  the  Term  that  relates  to  the  Codexis  IP  Rights,  Codexis  Process  and/or  any  Codexis  Enzyme
(collectively,  the  “Arch  Bio-Chemical  Improvements”).  Arch  and  its  Affiliates  agree  to  cooperate  with  Codexis,  at  Codexis’
reasonable request and expense, in the preparation of any patent application claiming any subject matter within such inventions and
intellectual property rights.

11.1.3    Codexis, at its own expense, shall have the sole right, but not the obligation, to file applications for and to
control  the  prosecution  and  maintenance  of  the  Codexis  IP  Rights,  including  without  limitation  any  and  all  intellectual  property
assigned by Arch to Codexis pursuant to Section 11.1.2, except as otherwise expressly noted.

11.2    Ownership by Arch.

11.2.1    As between the Parties, subject only to the licenses set forth in Article Error! Reference source not found.,

Arch shall retain all right, title and interest in, to and under the Arch Chemical Improvements.

11.2.2        Arch,  at  its  own  expense,  shall  have  the  sole  right,  but  not  the  obligation,  to  file  applications  for  and  to
control  the  prosecution  and  maintenance  of  the  intellectual  property  rights  embodied  in  the  Non-Codexis  Process  and  Arch
Chemical Improvements.

11.3    Enforcement.

11.3.1    At any time during the Term, if a Party determines that a Third Party is or may be infringing any Patent, or
may  have  misappropriated  any  other  right,  within  the  Codexis  IP  Rights,  the  Party  making  such  determination  shall  promptly
provide written notice to the other Party thereof.

11.3.2    Codexis, at its expense, shall have the right, but not the obligation, to enforce all rights (a) in the Codexis
Enzyme(s) and/or Codexis Process(es and any and all intellectual property rights therein, including without limitation the Codexis
IP Rights; and (b) with respect to any and all intellectual property assigned by Arch to Codexis pursuant to Section 11.1.2.

11.3.3        In  the  event  that  Codexis  enforces  its  rights  pursuant  to  this  Section  11.3,  Arch  and  its  Affiliates,  if
applicable, shall cooperate fully with Codexis in such enforcement, including without limitation, by joining as a party plaintiff and
executing such documents as Codexis may reasonably request.

11.4    Attorney in Fact. If Codexis cannot obtain the signature of Arch or its Affiliates, as applicable, on any document
necessary  to  exercise  its  rights  under  this  Article  11,  Arch  and  each  of  its  Affiliates  hereby  irrevocably  designates  and  appoints
Codexis and each of its duly authorized officers and agents as Arch’s agent and attorney-in-fact, to act for, and on behalf of Arch, to
execute and file any such document to further exercise Codexis’ rights or protections with the same force and effect as if executed
and delivered by Arch or its Affiliates. Exercise of the foregoing right shall be at the sole expense of Codexis, and Codexis agrees
to hold Arch and each of its Affiliates

[***] Certain information in this document has been omitted and filed separately with the Securities and Exchange
Commission. Confidential treatment has been requested with respect to the omitted portions.

harmless against any loss, liability, or expense that Arch may have to incur on account of the exercise by Codexis of such right.
This Section 11.4 shall not apply with respect to the execution and/or filing of any document in the event of any dispute between
the Parties with respect to the ownership provision under Section 11.1.2. If any document is executed and/or filed by Codexis on
behalf of Arch prior to any dispute between the two Parties on any matter contained in Section 11.1, such document shall not bind
Arch in any manner. On each occasion of exercise of the right conferred in the first sentence of this Section 11.4, Codexis agrees to
provide  a  written  notice  to  Arch  within  seven  (7)  days  after  such  exercise,  containing  material  particulars  of  the  document  filed
and/or executed.

11.5    Allocation of Recovery. Any recovery awarded by a court of competent jurisdiction or final resort in an unreversed,
unappealed, or unappealable decision or judgment from an action by Codexis to enforce any rights within the Codexis IP Rights,
including without limitation any and all intellectual property assigned by Arch to Codexis pursuant to Section 11.1.2, shall be first
applied  to  reimburse  Codexis’  and  Arch’s  unreimbursed  expenses  on  pro-rata  basis  in  proportion  to  their  expenses,  including
without limitation reasonable attorney’s fees and court costs. Any remaining amount of such damages or other monetary awards
shall then be applied between the Parties in such action or proceeding on a pro rata basis based upon the Parties’ respective out-of-
pocket expenses directly associated with such action or proceeding.

11.6    Termination for Patent Challenge. If Arch or any of its Affiliates challenges in a court of competent jurisdiction or
in any interference, re-examination or opposition proceeding, the validity, scope or enforceability of any Patent embodied in the
Codexis Enzyme(s) and/or Codexis Process(es, including without limitation the Codexis IP Rights, Codexis shall have the right to
terminate this Agreement immediately upon written notice to Arch provided in accordance with Section 16.7. If Applicable Law
prevents Codexis from termination of this Agreement pursuant to this Section 11.6, Arch acknowledges and agrees that Arch may
retain  the  licenses  granted  under  this  Agreement;  provided,  however,  that  the  relationship  between  the  Parties  in  respect  of  all
Products shall convert to a Non-Exclusive Relationship.

11.7    Third Party Claims. If, after the Effective Date, Arch becomes aware of any claims made by Third Parties that such
Third Party’s intellectual property may be infringed by the use, manufacture, having manufactured, marketing, selling, offering to
sell,  importing,  exporting,  and/or  other  distribution  of  any  Products,  Arch  shall  promptly  notify  Codexis  thereof.  If,  after  the
Effective  Date,  Codexis  becomes  aware  of  any  claims  made  by  Third  Parties  that  such  Third  Party’s  intellectual  property  rights
may be infringed by the use, manufacture, having manufactured, marketing, selling, offering to sell, importing, exporting, and/or
other distribution of any Codexis Enzymes or Codexis Process, Codexis shall promptly notify Arch thereof. The Parties shall meet
and discuss in good faith steps to avoid any such potential infringement, including without limitation whether to obtain rights to
practice under such Third Party-intellectual property, and, if so, which Party shall obtain such rights and the terms of obtaining such
rights and the relative sharing of the costs thereof.

13.1    Arch Indemnification. Arch shall indemnify, defend, and hold Codexis and its directors, officers, employees, agents,
and  Affiliates,  harmless  from  and  against  all  Third  Party  claims,  demands,  damages,  liabilities,  losses,  costs,  and  expenses,
including without limitation attorney’s fees (each, a “Claim”)  resulting  from  or  arising  out  of  (a)  any  breach  by  Arch  of  any  of
Arch’s representations, warranties, or covenants under Article 12; (b) the use, storage, handling, transportation, distribution, or any
other disposition of any Codexis Enzyme (while under the exclusive custody or control of Arch or any Affiliate of Arch) by Arch
or  any  Affiliate  of  Arch;  or  (c)  the  development,  testing,  manufacture,  use,  exportation,  storage,  handling,  transportation,  sale,
marketing,  distribution,  or  any  other  disposition  of  any  Product  (while  under  the  exclusive  custody  or  control  of  Arch  or  any
Affiliate of Arch) by Arch or any Affiliate of Arch; provided, however, that Arch’s indemnification obligations under this Section
13.1 shall not apply (i) to any such Claim arising out of Codexis’ negligence or willful misconduct; (ii) to the extent such Claim is
the  responsibility  of  Codexis  under  Section  13.2;  or  (iii)  to  the  extent  that  Arch  has  complied  with  all  Applicable  Laws  and  its
rights and obligations under this Agreement.

13.2       Codexis Indemnification. Codexis shall indemnify, defend, and hold Arch, and its directors, officers, employees,
agents, and Affiliates, harmless from and against all Third Party claims, demands, damages, liabilities, losses, costs, and expenses,
including without limitation attorney’s fees (each, a “Claim”) resulting from or arising out of (a) any breach by Codexis of any of
Codexis’ representations, warranties, or covenants under Article 12; or (b) the development, testing, manufacture, use, sale, offer
for sale, importation, exportation, storage, handling, transportation, distribution, or any other disposition of any Codexis Enzyme
(while  under  the  exclusive  custody  or  control  of  Codexis  or  any  Affiliate  of  Codexis)  by  Codexis  or  any  Affiliate  of  Codexis;
provided, however, that Codexis’ indemnification obligations under this Section 13.2 shall not apply (i) to any such Claim arising
out of Arch’s negligence or willful misconduct; (ii) to the extent such Claim is the responsibility of Arch under Section 13.1; or (iii)
to the extent that Codexis has complied with all Applicable Laws and its rights and obligations under this Agreement.

13.3    Procedure. For purposes of this Article 13, the indemnified Party shall give prompt written notice in accordance with
Section 16.7 to the indemnifying Party of any suits, claims, or demands by Third Parties or the indemnified Party that may give rise
to any Claim for which indemnification may be required under this Article 13; provided, however, that failure to give such notice
shall not relieve the indemnifying Party of its obligation to provide indemnification hereunder except if and to the extent that such
failure materially affects the ability of the indemnifying Party to defend the applicable suit, claim, or demand. The indemnifying
Party shall be entitled to assume the defense and control of any such suit, claim, or demand of any Third Party at its own cost and
expense; provided, however, that the indemnified Party shall have the right to be represented by its own counsel at its own cost in
such  matters.  In  the  event  that  the  indemnifying  Party  declines  to  or  fails  to  timely  assume  control  of  any  such  suit,  claim,  or
demand,  the  indemnified  Party  shall  be  entitled  to  assume  such  control,  conduct  the  defense  of,  and  settle  such  suit,  claim,  or
action, all at the sole cost and expense of the indemnifying Party. Neither the indemnifying Party nor the indemnified Party shall
settle or dispose of any such matter in any manner that would adversely affect the rights or interests of the other Party without the
prior written consent of the other Party, which shall not be unreasonably withheld or delayed. Each Party shall cooperate with the
other Party and its counsel in the course of the defense of any such suit, claim, or demand, such cooperation

to include, without limitation, using reasonable efforts to provide or make available documents, information, and witnesses.

13.4    Insurance.

13.4.1        During  the  Term,  each  Party  shall  maintain,  at  its  sole  cost  and  expense,  the  types  of  insurance  with
minimum limits as set forth in the applicable table in Exhibit 13.4.1. Notwithstanding anything to the contrary in Exhibit  13.4.1,
each Party shall be required to maintain product liability insurance with at least the following limits: (a) any limit mutually agreed
to by the Parties, (b) any limit required by a customer that requests to purchase at least Three Million Dollars ($3,000,000) worth of
Products collectively from the Parties and their Affiliates in any one (1) year period, or (c) at the point at which Parties and their
Affiliates collectively have sold an aggregate amount of at least Thirty Million Dollars ($30,000,000) worth of Products in any one
(1) year period, a combined single limit of not less than Ten Million Dollars ($10,000,000) per occurrence and in the aggregate.

13.4.2        Such  insurance  shall  insure  against  all  liability  arising  out  of  the  manufacture,  use,  sale,  distribution,  or
marketing of Products. The insurance will contain no more than an ordinary deductible. Such insurance shall be primary, without
regard  to  any  other  insurance  the  insured  Party  or  any  other  additional  insured  shall  maintain  or  otherwise  have  in  force.  The
Parties acknowledge and agree that such insurance shall not be construed to create a limit of either Party’s liability with respect to
its indemnification obligations under this Section 13.4. In the event that any of the required policies of insurance are written on a
claims made basis, then such policies shall be maintained during the entire term of this Agreement and for a period of not less than
five (5) years following the termination or expiration of this Agreement.

13.4.3    Each Party shall be named as an additional insured under the other Party’s Commercial General Liability,
Products  Liability  (as  applicable)  and  Umbrella  insurance  policies  to  the  extent  permitted  under  such  policies.  Such  additional
insured status shall end upon the termination or expiration of this Agreement unless the insuring Party’s policies are written on a
claims  made  basis,  in  which  case  such  additional  insured  status  shall  continue  for  the  period  of  time  that  such  insuring  Party  is
required to maintain such insurance under the terms of this Agreement.

13.4.4    Each Party will (a) furnish certificates of insurance to the other Party evidencing the required insurance and
additional insured status, as applicable, prior to the Effective Date and upon request thereafter and (b) provide the other Party with
written notice at least thirty (30) days prior to the cancellation, non-renewal or material change in such insurance that materially
adversely affects the rights of the other Party hereunder.

14.    DISPUTE RESOLUTION

14.1    Exclusive Dispute Resolution Mechanism. The Parties agree that the procedures set forth in this Article 14 shall be
the exclusive mechanism for resolving any disputes, controversies, or claims (collectively, “Disputes”) between the Parties that
may arise from time

[***] Certain information in this document has been omitted and filed separately with the Securities and Exchange
Commission. Confidential treatment has been requested with respect to the omitted portions.

to time pursuant to this Agreement relating to either Party’s rights and/or obligations hereunder that cannot be resolved through
good faith negotiation between the Parties.

14.2    Arbitration.

14.2.8    Any and all unresolved Disputes, except as set forth in Section 14.3 or Section 14.4, shall be exclusively

and finally resolved by binding arbitration.

14.2.9        Any  arbitration  concerning  a  Dispute  shall  be  conducted  in  London,  unless  otherwise  agreed  to  by  the
Parties in writing. Each and any arbitration shall be administered by the London Court of International Arbitration (“LCIA”), and
shall be conducted in accordance with LCIA Rules (the “Rules”), as such Rules may be amended from time to time. All arbitration
proceedings will be conducted in the English language.

14.2.10    Within ten (10) days after receipt of an arbitration notice from a Party, the Parties shall attempt in good
faith to agree on a single neutral arbitrator with relevant industry experience to conduct the arbitration. If the Parties do not agree
on  a  single  neutral  arbitrator  within  ten  (10)  days  after  receipt  of  an  arbitration  notice,  each  Party  shall  select  one  (1)  arbitrator
within fifteen (15) days after receipt of an arbitration notice and the two (2) Party-selected arbitrators shall select a third arbitrator
with  relevant  industry  experience  to  constitute  a  panel  of  three  (3)  arbitrators  to  conduct  the  arbitration  in  accordance  with  the
Rules. In the event that the two (2) Party-selected arbitrators are unable to select the third arbitrator due to lack of mutual consent,
the  Parties  shall  request  the  LCIA  to  appoint  an  independent  and  qualified  third  arbitrator  and  an  appointment  made  by  LCIA
pursuant to such request shall be binding on both the Parties. In the event that only one of the Parties selects an arbitrator within
fifteen (15) days after receipt of an arbitration notice, then such arbitrator shall be entitled to act as the sole arbitrator to resolve the
Dispute or any and all unresolved issues subject to the arbitration. Each and every arbitrator of the arbitration panel conducting the
arbitration must and shall agree to render an opinion within twenty (20) days after the final hearing before the panel.

14.2.11    The decision or award of the arbitrator(s) shall be final, binding, and incontestable and may be used as a
basis for judgment thereon in any jurisdiction. To the full extent permissible under Applicable Law, the Parties hereby expressly
agree  to  waive  the  right  to  appeal  from  the  decision  of  the  arbitrator(s),  there  shall  be  no  appeal  to  any  court  or  other  authority
(government  or  private)  from  the  decision  of  the  arbitrator(s),  and  the  Parties  shall  not  dispute  nor  question  the  validity  of  such
decision or award before any regulatory or other authority in any jurisdiction where enforcement action is taken by the Party in
whose favor the decision or award is rendered, except in the case of fraud. The arbitrator(s) shall, upon the request of either Party,
issue a written opinion of the findings of fact and conclusions of law and shall deliver a copy to each of the Parties. Each  Party
shall bear its own costs and attorney’s fees, and the Parties shall equally bear the fees, costs, and expenses of the arbitrator(s) and
the arbitration proceedings; provided, however,  that  the  arbitrator(s)  may  exercise  discretion  to  award  costs,  including  attorney’s
fees, to the prevailing Party. Without limiting any other remedies that may be available under Applicable Law, the arbitrator(s) shall
have no authority to award provisional remedies of any nature whatsoever, or punitive, special, consequential, or any other similar
form of damages except as expressly set forth in Section 16.2.

Commission. Confidential treatment has been requested with respect to the omitted portions.

14.3    Preliminary Injunctions. Notwithstanding anything in this Agreement to the contrary, and pursuant to Section 10.5,
a  Party  may  seek  a  temporary  restraining  order  or  a  preliminary  injunction  from  any  court  of  competent  jurisdiction  in  order  to
prevent immediate and irreparable injury, loss, or damage on a provisional basis, pending the decision of the arbitrator(s) on the
ultimate merits of any Dispute.

14.4    Patent Disputes. Notwithstanding anything in this Agreement to the contrary, any and all issues regarding the scope,
construction, validity, and enforceability of one or more Patents shall be determined in a court of competent jurisdiction under the
local patent laws of the jurisdictions having issued the Patent or Patents in question.

14.5    Confidentiality. All proceedings and decisions of the arbitrator(s) shall be deemed Confidential Information of each

of the Parties, and shall be subject to the terms and conditions of Article 10.

15.    TERM, TERMINATION and BUY-OUT RIGHT

15.1    Term. The term of this Agreement shall commence on the Effective Date and continue in full force and effect on a
Product-by-Product basis until February 16, 2020, unless extended by mutual agreement of the Parties and/or unless terminated at
an earlier date in accordance with Sections 15.2 or 15.3 (the “Term”).

15.2    Termination for Cause. If a Party breaches any material term or condition of this Agreement, the other Party may
notify  the  breaching  Party  in  writing  of  such  breach,  in  accordance  with  Section  16.7,  setting  forth  the  nature  of  the  breach  in
reasonable  detail.  If  the  breaching  Party  fails  to  cure  such  breach  (if  curable)  within  thirty  (30)  days  after  the  receipt  of  the
foregoing notice from the non-breaching Party, the non-breaching Party may terminate this Agreement effective immediately upon
delivery of a second written notice to the breaching Party. Any breach by an Affiliate of Arch of any of the terms and conditions of
this Agreement shall constitute a breach of this Agreement by Arch. In the event of a non-curable breach, the non-breaching Party
shall  be  entitled,  in  the  non-breaching  Party’s  sole  discretion,  to  immediately  terminate  on  a  Product-by-Product  basis  or  this
Agreement in its entirety.

15.3    Termination for Insolvency. To the extent permitted under Applicable Law, a Party may terminate this Agreement
upon thirty (30) days written notice to the other Party on or after the occurrence of any of the following events: (a) the appointment
of  a  trustee,  receiver  or  custodian  for  all  or  substantially  all  of  the  property  of  the  other  Party,  or  for  any  lesser  portion  of  such
property,  if  the  result  materially  and  adversely  affects  the  ability  of  the  other  Party  to  fulfill  its  obligations  hereunder,  which
appointment is not dismissed within sixty (60) days; (b) the determination by a court or tribunal of competent jurisdiction that the
other Party is insolvent such that a Party’s liabilities exceed the fair market value of its assets; (c) the filing of a petition for relief in
bankruptcy by the other Party on its own behalf, or the filing of any such petition against the other Party if the proceeding is not
dismissed or withdrawn within sixty (60) days thereafter; (d) an assignment by the other Party for the benefit of creditors; or (e) the
dissolution or liquidation of the other Party.

15.4    Effect of Expiration or Termination.

15.4.1    Upon expiration of this Agreement, on a Product-by-Product basis, pursuant to Section 15.1 (but not early
termination), the licenses in respect of such Product under Section 2.2 shall terminate unless Arch exercises the right provided in
Section 15.5 of this Agreement.

15.4.2    Upon expiration or termination of this Agreement by either Party for any reason, each Party shall promptly
return,  or  destroy  and  provide  written  certification  of  such  destruction  by  a  duly  authorized  officer  of  such  Party,  any  and  all
Confidential Information of the other Party in such first Party’s possession or control at the time of such expiration or termination,
provided  however,  if  Arch  is  entitled  to  exercise  its  right  under  Section  15.5  and  exercised  such  right,  then  Arch  shall  not  be
required to return or destroy any Confidential Information in Arch’s possession at the time of such expiration or termination which
Confidential Information is used to practice or exploit any right acquired by the exercise of the Option pursuant to Section 15.5
below.

15.4.3        Expiration  or  termination  of  this  Agreement  for  any  reason  shall  not  (a)  release  any  Party  from  any
obligation that has accrued prior to the effective date of such expiration or termination (including the obligation to pay amounts
accrued  and  due  under  this  Agreement  prior  to  the  expiration  or  termination  date  but  which  are  unpaid  or  become  payable
thereafter), (b) preclude any Party from claiming any other damages, compensation, or relief that it may be entitled to upon such
expiration or termination, or (c) terminate any right to obtain performance of any obligation provided for in this Agreement that
shall survive expiration or termination.

15.5    Right to acquire Product license on the occurrence of any Buy-Out Event. On the occurrence of any Buy-Out
Event, Arch shall have the right, but not the obligation, to acquire an irrevocable, royalty-free, perpetual and non-exclusive license
on  a  Product-by-Product  basis,  to  Codexis  IP  Rights,  Codexis  Enzymes  and  Codexis  Process  covering  the  manufacture  of  such
Codexis  Enzymes  that  are  used  to  further  manufacture  such  Product  for  a  one-time  lump-sum  consideration  of  [***]  (the
“Option”). The Option shall expire in ninety (90) days from the day of occurrence of the Buy-Out Event unless Arch exercises its
Option and makes the payment of the said consideration to Codexis within such ninety (90) day period. During such ninety (90)
day period, if the Buy-Out Event is other than bankruptcy or insolvency of Codexis or expiration of this Agreement, Codexis shall
continue to perform its obligations under the Agreement in respect of the Products not subject to the Buy-Out Event. The payment
above shall be Codexis’ sole compensation for such Option-exercise by Arch. In the event Arch exercises its Option, Codexis shall
render  reasonable  support  to  allow  Arch  to  effectively  utilize  the  rights  acquired  by  the  Option  exercise,  including  without
limitation,  introduction  of  appropriate  contacts  and  technology  support;  provided,  however,  such  support  shall  only  be  provided
during (and only during) scale up at Arch or a contract manufacturing organization designated by Arch and in no event for a period
longer than eight (8) weeks. Codexis’ obligations in respect of such support shall be limited to (i) phone and email support and (ii)
onsite  support  limited  to  ten  (10)  man-hours  per  week  provided  that  Arch  cover  all  out-of-pocket  travel  and  boarding  expenses.
Any  license  granted  to  Arch  pursuant  to  this  Section  15.5  shall  be  subject  to  the  following  restrictions:  (i)  Arch  may  not
manufacture any Codexis Enzymes for Third Parties; (ii) Arch may only manufacture Codexis Enzymes solely for use by Arch to
manufacture  Products  for  sale  by  Arch;  and  (iii)  Arch  may  not  sublicense  any  of  the  rights  granted  by  Codexis  to  Arch.
Furthermore, any license granted to Arch pursuant to this Section 15.5

[***] Certain information in this document has been omitted and filed separately with the Securities and Exchange
Commission. Confidential treatment has been requested with respect to the omitted portions.

shall  not  affect  (i)  Codexis’  ownership  rights  in  (or  Codexis’  rights  to  grant  additional  licenses  to)  Codexis  IP  Rights,  Codexis
Enzymes and Codexis Process or (ii) Codexis’ right to manufacture Codexis Enzymes that are subject to the product.

15.6       Survival. In  addition to any provisions  which  by  their  terms  survive  termination  or  expiration of this Agreement,

MERCK may have made commitments to other suppliers to mitigate the risk.

2.1.3 During  the  TERM  of  this  AGREEMENT,  MERCK  has  the  right  to  develop  at  any  time  a  direct
SUBSTANCE MANUFACTURER for not more than [***] percent ([***]%) of MERCK’s SUBSTANCE

necessary  technical  support  for  the  SUBSTANCE  MANUFACTURER  qualification  within  six  (6)
months of MERCK's request. MERCK will negotiate the price for such SUBSTANCE directly with
the  SUBSTANCE  MANUFACTURER  and  CODEXIS  will  not  be  involved  in  any  part  of  the
commercial  agreement.  Subject  to  Section  15.1,  MERCK  shall  not  acquire  any  SUBSTANCE

MANUFACTURE SUBSTANCE for CODEXIS for three (3) years with the term of such agreement
automatically  renewing  for  a  period  of  one  (1)  year  after  the  initial  three  (3)-year  term  expires
unless either [***] or CODEXIS delivers the other party a notice of non-renewal twelve (12) months
prior to the end of the initial three (3)-year term or the then current renewal term.

2.1.5 The PARTIES agree that within six (6) months of notification from MERCK, CODEXIS will have the
identify  and  qualify  a  second  SUBSTANCE  MANUFACTURER  defined  as
obligation 
"SECONDARY SUBSTANCE MANUFACTURER" for the MANUFACTURE of SUBSTANCE to be
made  on  its  behalf  for  MERCK.  MERCK  shall  pay  CODEXIS  a  one  time  [***]  fee  upon  the
qualification  and  successful  Quality  Audit  by  MERCK  of  the  "SECONDARY  SUBSTANCE
MANUFACTURER". Whether a Quality Audit was in fact successful or not shall be determined at
the  reasonable  discretion  of  MERCK.  MERCK  has  the  right  to  perform  a  Quality  Audit  of  such
SECONDARY  SUBSTANCE  MANUFACTURER  at  any  time  to  ensure  the  SUBSTANCE  is
MANUFACTURED in accordance with appropriate quality controls as agreed upon by the Parties
prior to commencement of MANUFACTURE of SUBSTANCE; provided, that MERCK shall pay to
CODEXIS the [***] fee referred to in the second sentence of this Section 2.1.5 within [***] months

the  SECONDARY  SUBSTANCE
MANUFACTURER, regardless if such qualification and Quality Audit were performed or completed,
unless  such  qualification  failed  or  the  Quality  Audit  was  unsuccessful  (in  which  event,  MERCK
shall  pay  the  [***]  fee  when  the  qualification  and  successful  Quality  Audit  do  occur).  If  the
SECONDARY  SUBSTANCE  MANUFACTURER  is  not  found  acceptable  by  MERCK,  then
CODEXIS  shall  use  commercially  reasonable  efforts  to  ensure  the  SECONDARY  SUBSTANCE
MANUFACTURER  rectifies  all  deficiencies  and  complies  with  the  applicable  quality  standards.
CODEXIS  will  be  solely 
the  SECONDARY  SUBSTANCE
MANUFACTURER  meets  all  applicable  standards. MERCK  shall  not  be  obligated  to  provide  any

quality deficiencies but may, at its

2.1.6 No  sooner  than  six  (6)  months  after  the  qualification  of  the  SECONDARY  SUBSTANCE
MANUFACTURER,  MERCK  shall  have  the  right  but  not  the  obligation  to  request  CODEXIS  to
qualify  a  third  SUBSTANCE  MANUFACTURER  to  be  defined  as  "TERTIARY  SUBSTANCE
MANUFACTURER". MERCK shall pay CODEXIS a one time fee of [***] upon the qualification and
successful Quality Audit by MERCK of the TERTIARY SUBSTANCE MANUFACTURER. Whether
a  Quality  Audit  was  in  fact  successful  or  not  shall  be  determined  at  the  reasonable  discretion  of
MERCK.  MERCK  has  the  right  to  perform  a  Quality  Audit  of  such  TERTIARY  SUBSTANCE
MANUFACTURER  at  any  time  to  ensure  the  SUBSTANCE  is  MANUFACTURED  in  accordance
with  appropriate  quality  controls  as  agreed  upon  by  the  PARTIES  prior  to  commencement  of
MANUFACTURE  of  SUBSTANCE;  provided,  that  MERCK  shall  pay  to  CODEXIS  the  [***]  fee
referred  to  in  the  second  sentence  of  this  Section  2.1.6  within  [***]  months  of  MERCK’s  initial
receipt of SUBSTANCE from the TERTIARY SUBSTANCE MANUFACTURER, regardless if such
qualification and Quality Audit were performed or completed, unless such qualification failed or the
Quality  Audit  was  unsuccessful  (in  which  event,  MERCK  shall  pay  the  [***]  fee  when  the
qualification  and  successful  Quality  Audit  do  occur). 
the  TERTIARY  SUBSTANCE
MANUFACTURER  is  not  found  acceptable  by  MERCK,  then  CODEXIS  shall  use  commercially
reasonable  efforts  to  ensure  the  SUBSTANCE  MANUFACTURER  rectifies  all  deficiencies  and
complies  with  the  applicable  quality  standards.  CODEXIS  will  be  solely  responsible  for  ensuring
the TERTIARY SUBSTANCE MANUFACTURER meets all applicable standards. MERCK shall not
be  obligated  to  provide  any  financial  or  other  support  to  the  TERTIARY  SUBSTANCE
MANUFACTURER  to  rectify  any  quality  deficiencies  but  may,  at  its  sole  discretion,  elect  to
participate in any corrective action should it desire to do so.

forecasts delivered pursuant to this Section 2.2.1.1 shall be binding on MERCK in respect of
the requirements set forth for the two full QUARTERS immediately following the delivery of

use SUBSTANCE in the MANUFACTURE of COMPOUND.

2.2.1.2 At least [***] days prior to the beginning of each QUARTER during the TERM, MERCK shall

thereunder is not greater than [***] and the delivery date for such SUBSTANCE is not less
than  [***]  from  the  date  such  FIRM  ORDER  is  received  by  CODEXIS.  In  no  event  shall
CODEXIS  be  obligated  to  satisfy  any  requirements  for  quantities  of  SUBSTANCE  in  any

MERCK shall deliver FIRM ORDERS for SUBSTANCE for the remainder of the then-current

FIRM ORDER is deemed rejected.

2.2.1.3 Should MERCK deliver a FIRM ORDER requesting that CODEXIS supply SUBSTANCE in
excess of MERCK’s most recent estimate of its requirements made available to CODEXIS
pursuant  to  Section  2.2.1.1,  CODEXIS  shall  use  reasonable  commercial  efforts  to  meet
such request for SUBSTANCE; however, in the event that CODEXIS will not be able to meet

CODEXIS’ obligations under this AGREEMENT.

2.2.1.4 MERCK  may  cancel  or  defer  any  portion  of  a  FIRM  ORDER  for  SUBSTANCE  which
exceeds the forecast for such QUARTER, in whole or in part, without penalty, provided that

3.2

Licenses.

3.2.1 Subject  to  the  terms  and  conditions  of  this  AGREEMENT,  including  without  limitation  Article  4.0,
CODEXIS  hereby  grants  to  MERCK  a  non-exclusive,  worldwide  license,  with  the  right  to
sublicense, under the CODEXIS PATENTS and CODEXIS KNOW-HOW to (i) use SUBSTANCE to
make,  have  made,  use,  import,  and  sell  COMPOUND  CONTROLLED  by  MERCK  and  its
AFFILIATES  or  PRODUCT  CONTROLLED  by  MERCK  and  its  AFFILIATES  in  the  TERRITORY;
and (ii) make and have made SUBSTANCE for the sole purpose of MANUFACTURING and selling
COMPOUND  CONTROLLED  by  MERCK  and  its  AFFILIATES  or  PRODUCT  CONTROLLED  by
MERCK and its AFFILIATES in the TERRITORY. For the avoidance of doubt, the license granted

LICENSES AND SUPPLY FEES

4.1

In consideration of the rights and licenses granted hereunder, MERCK, on behalf of itself, its AFFILIATES
and THIRD PARTY  SUPPLIERS,  shall  pay  CODEXIS  certain  licensing and supply fees as listed in this
Article 4.0.

4.1.4 ANNUAL LICENSE FEE.

An ANNUAL LICENSE FEE in the amount set forth on ATTACHMENT 2 will be paid to CODEXIS
by  MERCK.  The  first  ANNUAL  LICENSE  FEE  shall  be  set  forth  on  the  invoice  included  in  the
DELIVERY of the first shipment under the first FIRM ORDER for SUBSTANCE. The first ANNUAL
LICENSE  FEE  shall  be  paid  to  CODEXIS  by  MERCK  within  [***]  days  after  the  issuing  of  the
invoice  of  the  first  FIRM  ORDER  for  SUBSTANCE  hereunder.  The  first  ANNUAL  LICENSE  FEE
shall cover a period of one YEAR beginning on the date of such DELIVERY (such date, the “FIRST
FIRM  ORDER  DATE”)  and  ending  on  the  first  anniversary  of  the  FIRST  FIRM  ORDER  DATE.
MERCK shall not be obligated to place the first FIRM ORDER of SUBSTANCE until the first time
MERCK obtains approval by an applicable regulatory AGENCY in any country in the TERRITORY
to use SUBSTANCE in the MANUFACTURE of COMPOUND. No ANNUAL LICENSE FEE will be
paid if MERCK does not obtain approval by at least one (1) applicable regulatory AGENCY in any
country in the TERRITORY to use SUBSTANCE in the MANUFACTURE of COMPOUND. All future
ANNUAL  LICENSE  FEES  shall  be  due  and  payable  by  MERCK  within  [***]  days  of  each
subsequent  anniversary  of  the  FIRST  FIRM  ORDER  DATE.  Notwithstanding  the  foregoing,  the
ANNUAL LICENSE FEE for any particular YEAR shall not be owed by MERCK to CODEXIS if this
AGREEMENT  has  been  terminated  in  accordance  with  the  terms  and  conditions  hereof  and  the
effective  date  for  such  termination  is  prior  to  the  anniversary  date  of  the  applicable  YEAR.  For
clarity, ANNUAL LICENSE FEES are non-refundable, non-creditable and may not be prorated.

4.1.5 MILESTONE and SUBSTANCE FEES.

4.1.5.1 Consistent  with  the  obligations  of  MERCK  under  Section  4.1.5.2.1  of  the  CLSA  and  in
consideration  of  the  rights  granted  to  MERCK,  its  AFFILIATES,  and  THIRD  PARTY
SUPPLIERS under this AGREEMENT, MERCK shall pay CODEXIS the

[***] Certain information in this document has been omitted and filed separately with the Securities and Exchange
Commission. Confidential treatment has been requested with respect to the omitted portions.

 
payments set forth in this Section 4.1.2, for SUBSTANCE used by MERCK, its AFFILIATES,
or THIRD PARTY SUPPLIERS or MANUFACTURED by MERCK, its AFFILIATES, or THIRD
PARTY  SUPPLIERS  per  Section  3.2.1(ii)  (if  applicable).  MERCK’s  obligation  to  remit  the
payments set forth in this Section 4.1.2 shall continue until MERCK provides CODEXIS with
written notice that it is no longer using SUBSTANCE, CODEXIS KNOW-HOW or a process
covered by CODEXIS PATENTS to MANUFACTURE COMPOUND and/or PRODUCT.

4.1.5.1.1 MERCK will pay CODEXIS a one-time REGULATORY MILESTONE PAYMENT of
[***]  in  the  event  that  SUBSTANCE  is  utilized  in  the  MANUFACTURING  of  a
PRODUCT  that  receives  approval  of  a  HEALTH  REGISTRATION  for  such
PRODUCT in the United States, Europe, Japan, Korea or Canada. Such payment
will be non-refundable and non-creditable. The PARTIES acknowledge and agree
that such approval shall be given by the applicable AGENCY.

4.1.2.1.2  The  REGULATORY  MILESTONE  PAYMENT  set  forth  in  Section  4.1.2.1.1  is  in
addition  to  the  SUBSTANCE  supply  payments  as  described  in  Section  4.1.2.2.
For  avoidance  of  doubt,  the  milestone  payment  is  for  the  first  HEALTH
REGISTRATION  of  a  PRODUCT  in  any  of  the  United  States,  Europe,  Japan,
Korea or Canada and does not apply to successive HEALTH REGISTRATIONS.
The  PARTIES  acknowledge  and  agree  that  such  approval  shall  be  given  by  the
applicable AGENCY.

4.1.2.2    SUBSTANCE FEES. Subject to Section 9.1, MERCK shall pay CODEXIS a SUBSTANCE
FEE  for  the  purchase  of  SUBSTANCE  according  to  the  schedule  in  ATTACHMENT  3.  At
CODEXIS’  request,  but  not  more  than  once  per  year,  the  $/kg  of  SUBSTANCE  as  listed  in  the
schedule  in  TABLE  1  on  ATTACHMENT  3  will  be  adjusted  based  on  the  latest  ratio  of
COMPOUND SUBSTRATE to PRODUCT.

The following examples show the calculation of ANNUAL LICENSE FEES AND SUBSTANCE FEES. The examples are
for demonstration purposes only and remain subject to applicable adjustment under TABLE 1 on ATTACHMENT 3.

Reconciliation. Within [***] days following the end of each CALENDAR YEAR, the PARTIES shall review
the report provided by MERCK to CODEXIS as set forth in Section 17.2 of this AGREEMENT in order to
determine if the SUBSTANCE FEES paid by MERCK to CODEXIS during such CALENDAR YEAR were
calculated in conformance with this AGREEMENT. Any underpayment or overpayment by MECK will be
reflected on the invoice for its next FIRM ORDER. In addition, the PARTIES may mutually agree to

engage  in  such  reconciliation  at  any  time  during  the  TERM  for  any  period  of  time,  and  MERCK  shall
supply any information or documentation requested by CODEXIS for such reconciliation.

4.3

Minimum  Demand.  For  forecast  purposes  only,  MERCK  expects  to  purchase  a  minimum  of  [***]  of
SUBSTANCE  from  CODEXIS,  its  AFFILIATES,  or  THIRD  PARTY  SUPPLIERS  per  CALENDAR  YEAR,
provided the demand for SUBSTANCE exists, as subject to pending regulatory approvals worldwide. This
Section  4.3  provides  a  non-binding  forecast  based  on  current  SUBSTANCE  LOADING  FACTORS  and
COMPOUND cycle time and yields and does not commit MERCK to any minimum purchase or create any
financial obligation of MERCK to CODEXIS.

4.4

Payments in U.S. Dollars. All payments required pursuant to this Article 4.0 are based on U.S. dollars.

5.0

USE OF SUBSTANCE
5.1

Efficiency  of  SUBSTANCE.  Each  PARTY  will  use  commercially  reasonable  efforts  to  ensure  the
SUBSTANCE LOADING FACTOR during MANUFACTURE of COMPOUND is at or less than the INITIAL
SUBSTANCE  LOADING  FACTOR  when  MANUFACTURING  the  COMPOUND.    If  at  any  time  the
SUBSTANCE LOADING FACTOR [***], the PARTIES will [***].

5.2

Continuous  Improvement:  CODEXIS  is  committed  to  continue  evolving  the  SUBSTANCE  with  the
objective  to  reduce  the  SUBSTANCE  LOADING  FACTOR.  [***]  during  the  TERM  of  this  AGREEMENT,
CODEXIS can present to MERCK an improved strain of the SUBSTANCE ("IMPROVED SUBSTANCE")
that MERCK will [***] provided that:

5.2.1

5.2.2

Lab  work  by  MERCK  does  not  show  any  adverse  effect  in  COMPOUND  yield  or  cycle  time
attributed to the IMPROVED SUBSTANCE ;
Lab  work  by  MERCK  does  not  show  any  adverse  effect  in  the  COMPOUND  impurity  profile
attributed to the IMPROVED SUBSTANCE; and

5.2.3 Using the IMPROVED SUBSTACE [***] and, with respect to the IMPROVED SUBSTANCE, [***].
If after the adoption of the IMPROVED SUBSTANCE by MERCK in the commercial MANUFACTURE of
COMPOUND, MERCK identifies any issue in the commercial MANUFACTURE of COMPOUND attributed
to  the  use  of  the  IMPROVED  SUBSTANCE  which  is  adverse  to  the  commercial  MANUFACTURE  of
COMPOUND  in  a  material  way,  CODEXIS  agrees  to  immediately  switch  to  the  MANUFACTURE  of  the
SUBSTANCE  and  MERCK  will  be  released  from  any  requirement  to  further  evaluate  the  IMPROVED
SUBSTANCE.

[***] Certain information in this document has been omitted and filed separately with the Securities and Exchange
Commission. Confidential treatment has been requested with respect to the omitted portions.

5.3    SUBSTANCE Immobilization: MERCK may develop a SUBSTANCE immobilization process, where a small
amount  of  SUBSTANCE  will  be  used  (SUBSTANCE  LOADING  FACTOR  will  be  [***]%).  MERCK shall provide
written  notice  to  CODEXIS  that  it  has  employed  an  immobilization  process  in  the  commercial  scale.  In  such
event,  the  ANNUAL  LICENSE  FEE  will  remain  being  paid  in  accordance  with  ATTACHMENT  2,  but  the
SUBSTANCE  FEE  shall  be  modified  as  follows:  (a)  if  MERCK’s  pre-immobilization  SUBSTANCE  LOADING
FACTOR is greater than or equal to [***]%, then the SUBSTANCE FEE shall be determined in accordance with
ATTACHMENT  4  with  the  pre-immobilization  SUSTANCE  LOADING  FACTOR  set  at  [***]%;  or  (b)  if  MERCK’s
pre-immobilization  SUBSTANCE  LOADING  FACTOR  is  less  than  [***]%,  then  the  SUBSTANCE  FEE  shall  be
determined in accordance with ATTACHMENT 4 with the pre-immobilization SUBSTANCE LOADING FACTOR
set at MERCK’s current SUBSTANCE LOADING FACTOR. Any adjustments on SUBSTANCE FEE will be made
only for FIRM ORDERS for SUBSTANCE intended to be used for immobilization placed after the date of receipt
by CODEXIS of MERCK’s written notice that it has employed an immobilization process.

5.4    Third Party Enzyme.    MERCK will not engage a THIRD PARTY to make any derivatives of SUBSTANCE
but, for the avoidance of doubt, MERCK may use enzymes from THIRD PARTIES that are not SUBSTANCE and
that were discovered independently; provided, such enzymes and/or the use of such enzymes do not fall within
the scope of a VALID PATENT CLAIM of a CODEXIS PATENT.

5.5        USE  OF  SUBSTANCE.  MERCK  shall  not,  and  shall  not  allow  any  THIRD  PARTY  to,  without  the  prior
written  consent  of  CODEXIS,  (a)  extract  information  from,  reverse  engineer,  deconstruct,  disassemble,
sequence  or  in  any  way  determine,  or  attempt  to  extract  information  from,  reverse  engineer,  deconstruct,
disassemble, sequence or in any way determine, the biological, chemical or physical structure or composition of
any  SUBSTANCE  MANUFACTURED  by  CODEXIS;  (b)  copy,  alter,  modify  or  otherwise  design  or  create  any
variant or derivative of any such SUBSTANCE; or (c) transfer or disclose or otherwise provide access to any of
such SUBSTANCE or its variants, derivatives or components, or sequence information pertaining thereto, to a
THIRD PARTY.

hereunder  at 
the  qualified  SUBSTANCE  MANUFACTURER  FACILITY.  MANUFACTURING  of
SUBSTANCE  may  not  be  relocated  without  MERCK’s  prior  written  consent  (such  consent  not  to  be
unreasonably delayed or withheld). Any such relocation of the MANUFACTURING of SUBSTANCE shall
comply with all applicable LAWS and shall be made in accordance with ATTACHMENT 6.

CODEXIS  and  its  SUBSTANCE  MANUFACTURERS  shall  permit  one  or  more  qualified  technical
specialists  from  MERCK,  upon  reasonable  prior  notice  and  during  normal  business  hours,  to  conduct
audits or inspections (including, but not limited to, quality, safety, social responsibility, and environmental)
of  the  FACILITY  or  any  other  facility  which  is  proposed  to  be  used  to  MANUFACTURE  SUBSTANCE.
Material observations and conclusions of MERCK's audits will be issued to, and promptly discussed with,
CODEXIS.  CODEXIS  shall  provide  a  written  response  within  [***]  days  of  receipt  of  such  observations
and conclusions. The PARTIES will discuss such response and promptly agree on corrective action to be
implemented  in  the  event  such  observations  and  conclusions  establish  that  CODEXIS  and/or  its
SUBSTANCE  MANUFACTURERS  do  not  substantially  comply  with  the  applicable  MANUFACTURING
STANDARDS.  The  [***]  corrective  action  shall  be  implemented  by  CODEXIS  and  its  SUBSTANCE
MANUFACTURERS,  [***].  If  necessary,  [***]  in  order  to  ensure  that  any  such  corrective  actions  are

the day of DELIVERY. CODEXIS guarantees that no SUBSTANCE shall, at the time of DELIVERY,
be (a) adulterated or misbranded within the meaning of the U.S. Federal Food, Drug and Cosmetic

MERCK, shall test and inspect such SUBSTANCE for compliance with the representation, warranty
and covenant specified in Section 10.2.1(i). Within [***] days after the DELIVERY of a shipment of
SUBSTANCE, MERCK shall provide notice to CODEXIS of the result of the testing and inspection
in  writing;  provided  that  if  MERCK  fails  to  provide  such  notice  within  such  [***]  day  period,  the

testing shall be for the determination of financial liability only and shall not determine releasability
of  SUBSTANCE.  If  the  SUBSTANCE  is  determined  to  meet  such  representation,  warranty  and
covenant, then MERCK shall bear the cost of the independent laboratory testing and pay the fees
with  respect  to  the  SUBSTANCE  in  accordance  with  this  AGREEMENT.  If  the  SUBSTANCE  is
determined not to have met such representation, warranty and covenant, then CODEXIS shall bear
the cost of laboratory testing, and CODEXIS shall, at MERCK's election, either replace the rejected
SUBSTANCE within [***] days after the date of such determination, at no cost to MERCK, or refund
to MERCK the fees paid by MERCK for such SUBSTANCE(S), and the cost of all materials used

the representation, warranty and covenant specified in Section 10.2.1(i) occurred after DELIVERY
of  such  shipment  of  SUBSTANCE  by  CODEXIS.  Any  non-conformance  with  the  warranties
specified  in  this  Article  10.0,  as  it  relates  to  supply  of  SUBSTANCE  meeting  the  QUALITY
STANDARD  SPECIFICATIONS  agreed  to  by  the  PARTIES  at  the  time  of  DELIVERY  to  MERCK,
which reasonably could not have been discovered within such [***] day frame shall be reported to
CODEXIS  within  [***]  business  days  after  discovery  by  MERCK;  provided  that  CODEXIS  shall
have no responsibility for any such non-conformance if the cause leading to non-conformance was
any failure of MERCK.

10.2.3 Any  SUBSTANCE  which  fails  to  meet  the  warranties  under  Section  10.2.1  and  which  is  in

MERCK’s possession shall be destroyed at CODEXIS’ expense.

EFFECTIVE DATE, SUBSTANCE, methods of MANUFACTURE of SUBSTANCE, and methods of
use of such SUBSTANCE for making COMPOUND do not (i) infringe any VALID PATENT CLAIM
owned  or  possessed  by  a  THIRD  PARTY,  or  (ii)  breach  any  confidentiality  or  non-use  obligation
owed to a THIRD PARTY by CODEXIS.

AFFILIATE, subcontractor or agent in a capacity that may reasonably provide an opportunity to

business activities of MERCK or its AFFILIATES, that CODEXIS will conduct due diligence on such
subsidiary, AFFILIATE, subcontractor or agent consistent with the requirements as set forth in this
Section 19, and will maintain adequate records and provide such records to MERCK to evidence
such due diligence was conducted and any identified risks were mitigated. CODEXIS shall make all
further disclosures as necessary to ensure the information provided remains complete and accurate

compliance with this Section 19 for the period of two years following termination of this
AGREEMENT.

19.7 A  breach  by  either  PARTY  of  any  of  its  obligations  under  this  Section  19  shall  be  considered  a
material  breach  under  this  AGREEMENT.  MERCK  shall  have  the  right  to  terminate  this
AGREEMENT immediately upon any violation of this Section 19 or any breach of a representation or
warranty contained herein.

20.0 COMPLIANCE WITH THE LAW

20.1 CODEXIS shall comply  with  and  give  all  notices  required  by  LAWS,  bearing on the performance of
this  AGREEMENT  as  existing  on  the  EFFECTIVE  DATE  and  as  enacted  or  amended  during  the
TERM.  CODEXIS  shall  notify  MERCK  if  it  becomes  aware  of  any  material  non-compliance  in
connection  with  this  AGREEMENT  and  shall  take  all  appropriate  action  necessary  to  comply  with
such LAWS.

21.0 DISPUTE RESOLUTION

21.1The  PARTIES  shall  attempt  to  amicably  resolve  any  dispute  arising  out  of  or  relating  to  this
AGREEMENT. In the event that said negotiations are not successful within thirty (30) days
after the occurrence of such dispute, it shall be finally resolved through arbitration before
three (3) arbitrators, provided that such dispute is not an Excluded Claim. Such arbitration
shall  take  place  in  Chicago,  Illinois,  the  United  States  of  America  and  shall  proceed  in
accordance with the Commercial Arbitration Rules of the American Arbitration Association
(“AAA”).  Within  fifteen  (15)  calendar  days  of  either  PARTY  making  a  demand  for
arbitration,  MERCK  and  CODEXIS  shall  each  select  one  (1)  arbitrator.  A  third  arbitrator
shall  be  selected  by  the  arbitrators  selected  by  the  PARTIES  within  thirty  (30)  days  after
such  arbitrators  are  appointed.  In  the  event  that  either  PARTY  shall  fail  to  appoint  its
arbitrator, or the two arbitrators selected by the PARTIES fail to appoint the third arbitrator,
in either case within the prescribed time period, then either PARTY may apply to the AAA
for  the  appointment  of  such  arbitrator.  The  determination  of  a  majority  of  the  panel  of
arbitrators  shall  be  the  decision  of  the  arbitrators  and  shall  be  binding  regardless  of
whether one of the PARTIES fails or refuses to participate in the arbitration. Each PARTY

Commission. Confidential treatment has been requested with respect to the omitted portions.

shall pay for the arbitrator it selects with the cost of the third arbitrator being split equally between the
PARTIES. All other costs shall also be split equally between the PARTIES. Either PARTY may enter
any arbitration award in any court having jurisdiction or may make application to any such court for a
judicial  acceptance  of  the  award  and  order  of  enforcement,  as  the  case  may  be.  As  used  in  this
Section 21.1, the term “Excluded Claim” shall mean a dispute, controversy or claim that concerns (a)
the validity or infringement of a patent, trademark or copyright; or (b) any antitrust, anti-monopoly or
competition  law  or  regulation,  whether  or  not  statutory.  Any  and  all  issues  regarding  the  scope,
construction,  validity,  and  enforceability  of  one  or  more  patents  shall  be  determined  in  a  court  of
competent  jurisdiction  under  the  local  patent  LAWS  of  the  jurisdictions  having  issued  the  patent  or
patents in question. Notwithstanding anything to the contrary, each PARTY may seek injunctive relief,
including without limitation a temporary restraining order or a preliminary injunction, from any court of
competent  jurisdiction  in  order  to  prevent  immediate  and  irreparable  injury,  loss,  or  damage  on  a
provisional  basis,  pending  the  decision  of  the  arbitrator(s)  on  the  ultimate  merits  of  any  dispute,
controversy  or  claim.  All  proceedings  and  decisions  of  the  arbitrators  shall  be  deemed  confidential
information of each of the PARTIES, and shall be subject to ATTACHMENT 1 of this AGREEMENT.

22.0 NON-EXCLUSIVITY

SUBSTANCE and solely with respect to FIRM ORDERS for which the cost of SUBSTANCE exceeds Five Million

SUBSTANCE and solely with respect to FIRM ORDERS for which the cost of SUBSTANCE exceeds Five Million

SUBCONTRACTORS  for  the  MANUFACTURE  of  SUBSTANCE  and/or  provide  raw  materials  needed  for  the
MANUFACTURE of SUBSTANCE representing at least five percent (5%) of the aggregate cost of the total raw

SUBCONTRACTOR payments.

24.6          Notwithstanding  anything  herein  to  the  contrary,  any  non-compliance  with  this  Article  24.0  by

PPARTY  (as  defined  in  that  certain  Sitagliptin  Catalyst  Supply  Agreement  dated  as  of  the  date  hereof  between  MERCK  and
SUPPLIER (the “SUPPLY AGREEMENT”; capitalized terms used herein and not otherwise defined shall have the meaning herein
as  therein  defined)  or  its  AFFILIATES  has  disclosed  or  may  hereafter  disclose  to  the  other  PARTY  certain  confidential  and
proprietary  information  for  the  sole  purpose  of  enabling  SUPPLIER  to  analyze,  evaluate,  develop,  process,  utilize,  and/or
manufacture, including intermediates, COMPOUND, for MERCK and/or its AFFILIATES and for performing under the SUPPLY
AGREEMENT.  MERCK  and  SUPPLIER  agree  that  any  and  all  information,  know-how,  and  data,  whether  oral,  written,  or
graphical,  that  is  disclosed  or  provided  by  MERCK  or  its  AFFILIATES  to  SUPPLIER  or  by  SUPPLIER  to  MERCK  or  its

Except as set forth in the SUPPLY AGREEMENT, MERCK and SUPPLIER shall keep all INFORMATION of the other
PPARTY  in  confidence  and  will  not,  without  the  disclosing  PARTYPARTY's  prior  written  consent,  disclose  any
INFORMATION  of  the  disclosing  PARTY  to  any  person  or  entity,  except  those  officers,  employees,  agents,  or
AFFILIATES  of  the  receiving  PARTY  who  directly  require  the  INFORMATION.  Each  officer,  employee,  agent,  or
AFFILIATE to whom INFORMATION is to be disclosed shall be advised by the receiving PPARTY of the terms of this
AGREEMENT and shall be bound by the confidentiality and non-use obligations herein, mutatis mutandis. Both PARTIES
shall  take  all  reasonable  precautions  to  prevent  INFORMATION  of  the  other  PARTY  from  being  disclosed  to  any
unauthorized person or entity.

Except as set forth in the SUPPLY AGREEMENT, MERCK and SUPPLIER shall not use, either directly or indirectly, any
INFORMATION of the other PARTY disclosed to it hereunder, irrespective of whether such INFORMATION is disclosed
prior  to  the  effective  date  of  this  AGREEMENT,  for  any  purpose  other  than  for  the  sole  purpose  of  performing  its
obligations under the SUPPLY AGREEMENT without the disclosing PARTY’s prior written consent.

3.

The obligations of confidentiality set forth herein shall not apply to any INFORMATION that is:

[***] Certain information in this document has been omitted and filed separately with the Securities and Exchange
Commission. Confidential treatment has been requested with respect to the omitted portions.

(a)

lawfully possessed at any time by the receiving PARTY prior to receipt from the disclosing PARTY, as evidenced by
the receiving PARTY’s written records; or

(b) published  or  available  to  the  general  public  otherwise  than  through  the  receiving  PARTY’s  breach  of  this

AGREEMENT, or its breach of any other obligation of confidentiality; or

(c) obtained by the receiving PARTY from a THIRD PARTY with a valid right to disclose such INFORMATION, provided

that said THIRD PARTY is not under a confidentiality obligation to the disclosing PARTY; or

(d) independently  developed  by  employees  or  agents  of  the  receiving  PARTY  who  had  no  knowledge  of  the  disclosing

PARTY’s INFORMATION, as evidenced by the receiving PARTY’s written records.

Any  combination  of  features  or  disclosures  shall  not  be  deemed  to  fall  within  the  foregoing  exclusions  merely
because  individual  features  are  published  or  available  to  the  general  public  or  in  the  rightful  possession  of  the  receiving
PARTY unless the combination itself and principle of operation are published or available to the general public or in the
rightful possession of the receiving PARTY.

Except as set forth in the SUPPLY AGREEMENT, all INFORMATION, without limitation, shall remain the property of the
disclosing PARTY. Except as set forth in the SUPPLY AGREEMENT, neither PARTY shall acquire any license or any other
intellectual  property  interest  in  any  INFORMATION  disclosed  to  it  by  the  disclosing  PARTY.  Except  as  set  forth  in  the
SUPPLY AGREEMENT, disclosure of INFORMATION shall not result in any obligation to grant the receiving PARTY any
right in and to said INFORMATION.

SUPPLIER shall not perform or have performed any toxicity testing on COMPOUND, or any MERCK-designated key raw
material used to manufacture COMPOUND, unless and until SUPPLIER provides (i) written notice to MERCK and (ii) an
opportunity for the PARTIES to consult on the necessity and/or desirability of such toxicity testing.

Except as set forth in the SUPPLY AGREEMENT, upon the written request of the disclosing PARTY, the receiving PARTY
shall  immediately  either  return  to  the  disclosing  PARTY,  or  destroy,  all  INFORMATION  of  the  disclosing  PARTY,  in
accordance with the instructions of the disclosing PARTY, including all notes, summaries, and translations that have been
made  regarding  such  INFORMATION,  and  all  copies  of  the  foregoing.  In  the  event  destruction  is  requested  by  the
disclosing PARTY, the receiving PARTY shall certify such destruction in writing.

In the event that the PARTY receiving any INFORMATION is required by judicial or administrative process to disclose any
or all of the INFORMATION, said PARTY shall promptly notify the disclosing PARTY and allow the disclosing PARTY a
reasonable time and opportunity to oppose such process before disclosing any INFORMATION. Notwithstanding anything
in this AGREEMENT to the contrary, MERCK shall have the right to disclose any INFORMATION to a regulatory agency
to the extent required or requested by such agency in connection with any regulatory filing, inspection or otherwise.

Any  disclosure  made  pursuant  to  this  Section  7  shall  not  affect  the  confidential  nature  of  the  disclosed  INFORMATION
(except to the extent the disclosure was made publicly available, such as but not limited to filings with the United States
Securities  and  Exchange  Commission,  in  which  case  such  disclosed  INFORMATION  shall  no  longer  be  deemed
confidential).

No agency or partnership relationship between MERCK and SUPPLIER, either express or implied, shall be created by this
AGREEMENT. Except as set forth in the SUPPLY AGREEMENT, each PARTY agrees to keep the existence and nature of
the relationship between the PARTIES as well as the terms of this AGREEMENT confidential and not to use the names of
the other PARTIES in any publicity or advertisement with regard to this AGREEMENT, without the prior written consent of
the other PARTY.

The confidentiality and non-use obligations created by this AGREEMENT shall be binding upon MERCK and SUPPLIER,
and  shall  inure  to  the  benefit  of,  and  be  enforceable  by,  their  respective  successors  and  assigns,  and  shall  continue  with
respect to each item of INFORMATION until the earlier of (i) the occurrence of any of the conditions set forth in Section 3
with respect to such item, or (ii) ten (10) years following the expiration or termination of the SUPPLY AGREEMENT.

This AGREEMENT, together with the SUPPLY AGREEMENT, embodies the entire understanding of the PARTIES with
respect to the subject matter hereof and supersedes and replaces any and all prior understandings and arrangements, oral or
written,  relating  to  the  INFORMATION  except  for  any  other  confidentiality  agreement  between  or  among  the  PARTIES
hereto.

This  AGREEMENT  shall  be  interpreted,  construed  and  enforced  in  accordance  with  the  laws  of  the  State  of  New  York,
without regard or reference to any of its rules or provisions governing conflict of laws.

The PARTIES shall attempt to resolve amicably any dispute arising out of or relating to this AGREEMENT through good
faith negotiations. In  the  event  that  said  negotiations  are  not  successful,  the  dispute  shall  be  resolved  through  arbitration
before three (3) arbitrators. Such arbitration shall take place in Chicago, Illinois and shall proceed in accordance with the
Commercial  Arbitration  Rules  of  the  American  Arbitration  Association  (“AAA”).  Within  fifteen  (15)  calendar  days  of
either PARTY making a demand for arbitration, MERCK and SUPPLIER shall each select one (1) arbitrator. Within thirty
(30)  days  of  a  demand  for  arbitration,  a  third  arbitrator  shall  be  selected  by  the  arbitrators  selected  by  the  PARTIES.  If,
within the prescribed time, either PARTY shall fail to appoint its arbitrator, or the two arbitrators selected by the PARTIES
fail to appoint the third arbitrator, then either PARTY may apply to the AAA for the appointment of such third arbitrator.
The determination of a majority of the panel of arbitrators shall be the decision of the arbitrators and shall be binding upon
the PARTIES regardless of whether one of the PARTIES fails or refuses to participate in the arbitration. The decision of the
arbitrators shall be enforceable by any court of competent jurisdiction. Each PARTY shall pay for its arbitrator, with all fees
and expenses of the third arbitrator being split equally between the PARTIES. All other expenses directly associated with
holding  an  arbitration  proceeding  shall  be  split  equally  between  the  PARTIES.  Either  PARTY  may  enter  any  arbitration
award in any court having jurisdiction

Commission. Confidential treatment has been requested with respect to the omitted portions.

or may make application to any such court for a judicial acceptance of the award and an order of enforcement, as the case
may be.

Notwithstanding anything to the contrary in Section 12, each PARTY understands and agrees that any use or disclosure of
INFORMATION  of  the  other  PARTY  in  violation  of  this  AGREEMENT  will  cause  such  other  PARTY  irreparable  harm
leaving  it  without  an  adequate  legal  remedy  and  shall  therefore  entitle  the  other  PARTY,  among  all  other  remedies,  to
injunctive relief from any court having jurisdiction.

If any provision of this AGREEMENT is found invalid or unenforceable by a court of competent jurisdiction, the remainder
of  this  AGREEMENT  shall  continue  in  full  force  and  effect.  The  PARTIES  shall  negotiate  in  good  faith  to  substitute  a
valid, legal, and enforceable provision that reflects the intent of such invalid or unenforceable provision.

It is understood and agreed that no failure or delay by either PARTY in exercising any right, power, or privilege hereunder
shall  operate  as  a  waiver  thereof,  nor  shall  any  single  or  partial  exercise  thereof  preclude  any  other  or  further  exercise
thereof or the exercise of any right, power, or privilege hereunder.

IN WITNESS WHEREOF, the PARTIES hereto have executed this AGREEMENT as of the 1st day of February, 2012.

to a Licensed Product. For purposes of clarification, as between the Parties, LICENSEE shall own all Regulatory Filings.

5.1.2    In the event that (a) within [***] after the date on which an ANDA is filed in the United States with respect
to a Licensed Product, LICENSEE or a sublicensee has not made a Regulatory Filing with respect to such Licensed Product in a

Filing in such country, then LICENSOR shall provide written notice thereof to LICENSEE, such notice to specify the particular

license granted hereunder with respect to such country only shall revert to LICENSOR.

5.2        Responsibilities  of  LICENSOR.  LICENSOR  shall  (a)  transfer  to  LICENSEE  or  its  designee  any  and  all

limitation,  training  personnel  of  LICENSEE  or  its  designee  in  relevant  processes  and  test  procedures,  and  (d)  upon  the  written
request of LICENSEE, file an ANDA on LICENSEE’s behalf (and at LICENSEE’s expense) with respect to a Licensed Product. In
addition, in the event that the practice of the license granted by LICENSOR to LICENSEE under Section 3.1 is found by a court of
competent  jurisdiction  to  infringe  any  intellectual  property  rights  of  any  Third  Party,  LICENSOR  shall  use  its  best  efforts,  at
LICENSOR’s sole cost and expense, to develop a non-infringing formulation for Compound and will license such formulation to
LICENSEE under terms contained herein.

6.    PAYMENTS, REPORTS AND RECORDS

earned by LICENSEE.

6.2        Notwithstanding  anything  to  the  contrary,  in  the  event  that  average  Fully  Burdened  Manufacturing  Cost  for  all
Licensed  Products  manufactured  during  any  calendar  quarter  exceeds  the  average  Net  Sales  for  such  Licensed  Products  in  any
[***]  ([***])  consecutive  calendar  quarters,  LICENSEE  shall  have  the  right  to  suspend  sales  of  Licensed  Product  upon  written
notice to LICENSOR at least [***] ([***]) days prior to suspension of sales. For  purposes  of  clarification,  any  such  suspension

following the receipt of such notice to suspend sales, LICENSOR shall have the right, but not the obligation, upon [***] ([***])
days written notice to terminate the rights and license granted hereunder; provided further that in such event, LICENSOR shall pay

Payments.  All  reports  provided  to  LICENSOR  by  LICENSEE  pursuant  to  this  Article  6  shall  be  deemed  to  be  Confidential
Information of LICENSEE.

6.6        LICENSEE  shall  keep  complete,  true,  and  accurate  books  of  account  and  records  for  the  purpose  of  showing
LICENSEE’s calculations of all amounts payable to LICENSOR under this Agreement. Such books and records shall be kept at

obligations of confidentiality and non-use no less restrictive than as set forth with respect to Confidential Information in Article 7.

7.    CONFIDENTIALITY

7.1        In  General.  The  Parties  have  provided  to  each  other  prior  to  the  Effective  Date,  and  in  connection  with  this
Agreement may in the future provide to each other, Confidential Information, including but not limited to each Party’s know-how,
invention  disclosures,  patent  applications,  proprietary  materials  and/or  technologies,  economic  information,  business  or  research
strategies, trade secrets, and material embodiments thereof.

7.2    Non-Disclosure and Non-Use. The receiving Party shall maintain the Confidential Information of the disclosing Party
in confidence, shall not disclose such Confidential Information to any Third Party, and shall not use such Confidential Information
for  any  purpose  except  as  expressly  permitted  under  the  terms  and  conditions  of  this  Agreement.  Notwithstanding  the  previous
sentence,  the  receiving  Party  may  disclose  the  Confidential  Information  of  the  disclosing  Party  to  its  employees,  agents,
consultants,  and  professional,  scientific,  medical,  and  legal  advisors  who  have  a  reasonable  need  to  know  such  Confidential
Information to carry out such Party’s obligations under this Agreement; provided that any such person to whom disclosure is made
is bound by written or code of professional conduct obligations of non-disclosure and non-use no less restrictive then those set forth
herein. The receiving Party shall take the same degree of care that such Party uses to protect its own confidential and proprietary
information of a similar nature and importance, but in no event shall such care be less than reasonable care.

7.3        Exceptions.  The  obligations  of  non-disclosure  and  non-use  under  Section  7.2  will  not  apply  as  to  particular
Confidential  Information  of  a  disclosing  Party  to  the  extent  that  such  Confidential  Information:  (a)  is  at  the  time  of  receipt,  or
thereafter becomes, through no fault of the receiving Party, publicly known or available; (b) is known by the receiving Party or its
Affiliates at the time of receiving such information, as evidenced by written records; (c) is hereafter furnished to the receiving Party
or its Affiliates by a Third Party without breach of a duty to the disclosing

[***] Certain information in this document has been omitted and filed separately with the Securities and Exchange
Commission. Confidential treatment has been requested with respect to the omitted portions.

Party; or (d) is independently discovered or developed by the receiving Party or its Affiliates without use of, application of, access
to, or reference to Confidential Information of the disclosing Party, as evidenced by written records.

7.4        Disclosure  Required  by  Law.  Disclosure  of  Confidential  Information  shall  not  be  precluded  if  such  disclosure  is
required under applicable laws or regulations or an order by of a Governmental Authority having competent jurisdiction; provided,
however, that the receiving Party shall first have given reasonable prior written notice to the disclosing Party pursuant to Section
12.12, and shall have made a reasonable effort to obtain a protective order, or to cooperate with the disclosing Party’s efforts, as
applicable,  to  obtain  a  protective  order  limiting  the  extent  of  such  disclosure  and  requiring  that  the  Confidential  Information  so
disclosed  be  used  only  for  the  purposes  for  which  such  receiving  Party  is  legally  required  to  disclose  such  Confidential
Information.

7.5    Remedies. The receiving Party agrees that its obligations under this Article 7 are necessary and reasonable to protect
the  disclosing  Party’s  business  interests  and  that  the  unauthorized  disclosure  or  use  of  Confidential  Information  of  a  disclosing
Party  will  cause  irreparable  harm  and  significant  injury,  the  degree  of  which  may  be  difficult  to  ascertain.  The  receiving  Party
further acknowledges and agrees that in the event of any actual or threatened breach of this Article 7, the disclosing Party may have
no adequate remedy at law and, accordingly, that the disclosing Party will have the right to seek an immediate injunction enjoining
any breach or threatened breach of this Article 7, as well as the right to pursue any and all other rights and remedies available at law
or in equity for such breach or threatened breach. It is expressly agreed that the Party to be enjoined will not seek posting of bond
and will not contest the bond requirement.

7.6    Agreement Terms.    The terms and conditions of this Agreement shall be Confidential Information of the Parties, and

subject to the terms of this Article 7.

7.7    Survival. All obligations of non-disclosure and non-use imposed pursuant to the terms and conditions of this Article 7
shall survive expiration or termination of this Agreement and continue in full force and effect for a period of [***] ([***]) years
after the effective date of such expiration or such termination.

8.    INTELLECTUAL PROPERTY

Technology. Ownership of patents and patent applications covering Improvements shall be determined in accordance with the rules
of inventorship under U.S. patent law.

8.2    Filing, Prosecution and Maintenance by LICENSEE. With respect to the Licensed Patent Rights, LICENSOR shall

[***] Certain information in this document has been omitted and filed separately with the Securities and Exchange
Commission. Confidential treatment has been requested with respect to the omitted portions.

patent applications in those countries where LICENSEE requests that LICENSOR file such applications;

8.2.2        to  take  all  reasonable  steps  to  prosecute  all  pending  and  new  patent  applications  included  within  such

Licensed Patent Rights;

8.2.3    to respond to oppositions, nullity actions, re-examinations, revocation actions and similar proceedings filed

8.2.4    to maintain in force any letters patent included in such Licensed Patent Rights by duly filing all necessary

papers and paying any fees required by the patent laws of the particular country in which such letters patent were granted.

LICENSOR shall cooperate fully with, and take all necessary actions requested by, LICENSEE in connection with the preparation,
prosecution  and  maintenance  of  any  letters  patent  included  in  Licensed  Patent  Rights.  LICENSOR  and  LICENSEE  shall  share
equally all prosecution and maintenance expenses; provided, however, that in the event that LICENSEE funds the development of
the Exhibit Batches for any Licensed Product, LICENSEE shall pay [***] percent ([***]%) of such costs incurred after the date of
ANDA filing for such Licensed Product and LICENSOR shall pay [***] percent ([***]%) of such costs.

LICENSOR shall notify LICENSEE in a timely manner of any decision to not file a patent application or to abandon a pending
application  or  an  issued  patent  included  in  such  Licensed  Patent  Rights.  Thereafter,  LICENSEE  shall  have  the  option,  at  its
expense,  of  filing  such  an  application,  or  continuing  to  prosecute  any  such  pending  patent  application  or  of  keeping  the  issued
patent in force, as applicable. In the event that LICENSEE exercises such option for any such pending application or such issued
patent,  (a)  LICENSOR  shall  assign  to  LICENSEE  such  pending  application  or  such  issued  patent,  as  the  case  may  be,  and  (b)
LICENSEE’s payment obligations hereunder shall terminate as of the date of such assignment.

8.3    Copies of Documents. LICENSOR shall provide to LICENSEE copies of all patent applications that are a part of the
Licensed Patent Rights prior to filing, for the purpose of obtaining substantive comment of LICENSEE patent counsel. LICENSOR
shall also provide to LICENSEE copies of all documents relating to prosecution of all such patent applications in a timely manner
and shall provide to LICENSEE every [***] ([***]) months a report detailing their status.

8.4    Notice. Each Party shall promptly provide notice to the other Party of any alleged infringement by a Third Party of any
Licensed  Patent  Rights  and,  together  with  such  notice,  provide  the  other  Party  with  all  available  evidence  of  such  alleged
infringement.

8.5        Enforcement  by  LICENSOR.  During  the  term  of  this  Agreement,  LICENSOR  shall  have  the  right,  but  not  the
obligation,  to  institute  legal  action  against  a  Third  Party  for  infringement  of  any  Licensed  Patent  Right.  In  the  event  that
LICENSOR  initiates  legal  action  against  infringement  of  the  Licensed  Patent  Rights,  LICENSOR  shall  notify  LICENSEE  in
writing. Thereafter, LICENSEE shall have a right, in LICENSEE’s sole discretion and at LICENSEE’s

expense, to join or otherwise participate or not to join or otherwise participate in such legal action with legal counsel selected by
LICENSEE. Any recovery received by LICENSOR from legal action initiated pursuant to this Section 8.5, whether by judgment,
award,  decree  or  settlement,  shall  be  used  first  to  reimburse  LICENSOR  for  LICENSOR’s  out‑of‑pocket  costs  and  expenses
actually incurred in pursuing such legal action, and second to reimburse LICENSEE for LICENSEE’s costs and expenses actually
incurred in connection with such legal action. The remainder of any recovery received by LICENSOR under this Section 8.5, after
reimbursement of costs and expenses of LICENSOR and LICENSEE, shall be shared by LICENSOR and LICENSEE in proportion
to each Party’s share of the Profits as set forth in Section 6.1.2.

8.6    Enforcement by LICENSEE. In the event that LICENSOR elects not to initiate legal action for infringement of any
Licensed  Patent  Rights  within  [***]  ([***])  days  after  the  delivery  of  a  notice  of  potential  infringement  to  either  Party  in
accordance with Section 8.4, LICENSEE, after not less than [***] ([***]) days prior written notice to LICENSOR, may initiate
legal action for patent infringement and, to the extent necessary to initiate and maintain such legal action, join LICENSOR as a
party  plaintiff.  LICENSEE  shall  have  the  right  to  compromise,  litigate,  settle  or  otherwise  dispose  of  any  such  legal  action;
provided,  however,  LICENSEE  shall  keep  LICENSOR  informed  of  the  status  of  any  such  legal  action  in  a  timely  manner.
LICENSEE shall bear the entire cost of such legal action, and shall be entitled to retain the entire amount of any recovery. In any
such legal action, LICENSOR shall have the right, but not the obligation, at LICENSOR’s expense, to be represented by counsel of
LICENSOR’s choosing.

8.7    Defense of Infringement Claims. LICENSOR will cooperate with LICENSEE in the defense of any suit, action or
proceeding against LICENSEE or any sublicensee of LICENSEE alleging the infringement of the intellectual property rights of a
Third Party by reason of the use of Licensed Technology in the manufacture, use, offer for sale, sale or importation of a Licensed
Product. LICENSEE shall give LICENSOR prompt written notice of the commencement of any such suit, action or proceeding or
claim of infringement and will furnish LICENSOR a copy of each communication relating to the alleged infringement. LICENSOR
shall give to LICENSEE all authority (including the right to exclusive control of the defense of any such suit, action or proceeding
and the exclusive right after consultation with LICENSOR, to compromise, litigate, settle or otherwise dispose of any such suit,
action or proceeding), at LICENSEE’s expense, including by providing information and assistance necessary to defend or settle any
such  suit,  action  or  proceeding;  provided, however,  LICENSEE  shall  keep  LICENSOR  informed  of  the  status  of  any  such  suit,
action or proceeding in a timely manner.

8.8    Cooperation. In any suit or legal action to enforce and/or defend the Licensed Patent Rights, the Party not in control
of  such  suit  or  legal  action,  at  the  reasonable  request  of  the  controlling  Party,  shall  cooperate  in  all  respects  and,  to  the  extent
reasonably  possible,  have  its  employees  testify  when  request  and  make  available  relevant  records,  papers,  information,  samples,
specimens, and the like.

9.2    Termination Upon Material Breach. Upon any material breach of, or default under, Section 6.1 of this Agreement by
LICENSEE,  LICENSOR  may  terminate  this  Agreement  by  [***]  ([***])  days  written  notice  to  LICENSEE.  Said  notice  shall
become effective at the end of such period unless during said period LICENSEE shall cure such defect or default.

9.3       Termination by LICENSEE. LICENSEE shall have the right to terminate this Agreement at any time upon [***]
([***])  days  written  notice  to  LICENSOR  in  the  event  that  (a)  within  [***]  ([***])  days  after  the  Effective  Date,  LICENSEE
makes  a  good  faith  determination  that  the  Licensed  Technology  infringes  U.S.  Patent  Number  5,214,052,  (b)  prior  to  the
commercial launch of any Licensed Product, any Third Party, other than [***] or any of its successors or assigns (“[***]”) or [***]
or any of its successors or assigns (“[***]”), alleges that the Licensed Technology infringes any intellectual property right owned or
otherwise controlled by such Third Party, or (c) a court of competent jurisdiction renders a final judgment or determination that the
Licensed Technology infringes any intellectual property right owned or otherwise controlled by any Third Party, including without
limitation  [***]  or  [***],  or  (d)  the  commercialization  of  any  Licensed  Product  by  LICENSEE  creates  a  conflict  with  any  of
LICENSEE’s  partners,  or  (e)  LICENSEE  makes  a  good  faith  determination  that  any  Licensed  Product  is  not  suitable  for
commercial use, where “not suitable for commercial use” means, for example, that such Licensed Product is not safe, not effective,
unstable, impure, fails to scale up, fails analytical validation or fails to have suitable shelf life; provided that such unsuitability is
not caused by the API supplied by the LICENSEE.

9.4        Termination  by  LICENSOR.  LICENSOR  shall  have  the  right  to  terminate  this  Agreement  in  accordance  with

Section 6.2.

9.5    Consequences of Expiration or Termination. Upon expiration of this Agreement in accordance with Section 9.1, but
not early termination, the rights and licenses granted by LICENSOR to LICENSEE pursuant to Article 3 shall become fully paid-
up, royalty  free and  irrevocable.  In  the  event  of  termination  of  this  Agreement,  each  Party  shall  promptly  return,  or  at  the  other
Party’s  request  destroy,  any  Confidential  Information  of  the  other  Party  in  such  Party’s  possession  or  control  at  the  time  of
termination. In the case of termination of this Agreement (a) by LICENSOR pursuant to Section 9.2 or 9.4, or (b) by LICENSEE
pursuant to Section 9.3, the rights and license granted hereunder to LICENSEE shall terminate. In the case of termination of this
Agreement by LICENSOR pursuant to Section 9.2 or 9.4, LICENSEE shall supply LICENSOR with API for any Licensed Product
at a transfer price equal to the [***] for such API plus [***] percent ([***]%); provided that a court of competent jurisdiction has
not  held  that  the  Licensed  Technology  infringes  the  intellectual  property  rights  of  any  Third  Party;  provided  further  that  such
supply does not conflict with any contractual obligations of LICENSEE. In the event of any termination of this Agreement, (i) any
sublicense  granted  by  LICENSEE  prior  to  the  effective  date  of  such  termination  shall  survive  such  termination,  and  (ii)  all
sublicense  royalties  or  other  sublicense-related  consideration  that  the  sublicensee  would  have  owed  to  LICENSEE  under  such
sublicense shall be paid by such sublicensee to LICENSOR.

9.6    Survival. Articles 2, 4, 7, and 12 and Sections 3.3, 6.6, 8.1, 9.5, 9.6, and 11.4 shall survive expiration or termination of

[***] Certain information in this document has been omitted and filed separately with the Securities and Exchange
Commission. Confidential treatment has been requested with respect to the omitted portions.

shall survive expiration, but not termination, of this Agreement, and (b) in the event that LICENSOR terminates this Agreement
pursuant to Section 9.4, Section 6.2 shall survive.

have  the  right  to  transfer  or  assign  its  rights  and  obligations  under  this  Agreement,  without  consent,  to  a  successor  to  all  or
substantially all of its business or assets relating to this Agreement whether by sale, merger, business reorganization, operation of
law, or otherwise. Subject  to  the  foregoing,  this  Agreement  is  binding  upon  and  inures  to  the  benefit  of  the  Parties,  and  to  their

12.    GENERAL

12.1    Further Actions. From time to time on and after the Effective Date, each Party shall at the reasonable request of the

waiver by a Party of any of the terms and conditions of this Agreement in any instance will not be deemed or construed to be a

provision or of this Agreement. The Parties will make a good faith effort to replace the invalid or unenforceable provision with a
valid one which in its economic effect is most consistent with the invalid or unenforceable provision.

matter thereof, and all prior and contemporaneous negotiations,

representations, agreements and understandings are merged into, extinguished by, and completely expressed by it.

unless consented to in writing and signed by such Party. Signatures and writings in an electronic form do not constitute or create a
writing signed by a Party.

12.7    Captions. The captions to this Agreement are for convenience only, and are to be of no force or effect in construing

or interpreting any of the provisions of this Agreement.

the laws of any State other than the State of New York.

12.9    Arbitration.

12.9.1        The  Parties  agree  the  procedures  set  forth  in  this  Section  12.9  shall  be  the  exclusive  mechanism  for
resolving any bona fide disputes, controversies or claims (collectively, “Disputes”) between the Parties that arise from time to time
pursuant to this Agreement relating to any Party’s rights and/or obligations hereunder that cannot be resolved through good faith
negotiation between the Parties.

12.9.2    Any and all unresolved Disputes, except as set forth in Sections 12.9.6 or 12.9.7 below, shall be exclusively

and finally resolved by binding arbitration.

12.9.3        Any  arbitration  concerning  a  Dispute  submitted  by  LICENSOR  shall  be  conducted  in  San  Francisco,
California, unless otherwise agreed to by LICENSOR and LICENSEE in writing. Any arbitration concerning a Dispute submitted
by LICENSEE shall be conducted in Reston, Virginia, unless otherwise agreed to by LICENSEE and LICENSOR in writing. Each
and any arbitration shall be administered by the American Arbitration Association (“AAA”), and shall be conducted in accordance
with the Commercial Arbitration Rules of the AAA (the “Rules”), as such Rules may be amended from time to time.

12.9.4    Within ten (10) days after receipt of an arbitration notice from a Party, the Parties shall attempt in good faith
to agree on a single neutral arbitrator with relevant industry experience to conduct the arbitration. If the Parties do not agree on a
single neutral arbitrator within ten (10) days after receipt of an arbitration notice, each Party shall select one (1) arbitrator and the
two (2) Party-selected arbitrators shall select a third arbitrator with relevant industry experience to constitute a panel of three (3)
arbitrators to conduct the arbitration in accordance with the Rules. In the event that only one of the Parties selects an arbitrator, then
such  arbitrator  shall  be  entitled  to  act  as  the  sole  arbitrator  to  resolve  the  Dispute  or  any  all  unresolved  issues  subject  to  the
arbitration. Each and all arbitrator(s) of the arbitration panel conducting the arbitration must and shall agree to render an opinion
within twenty (20) days after the final hearing before the panel.

Commission. Confidential treatment has been requested with respect to the omitted portions.

12.9.5       The decision or award of the arbitrator(s) shall be final, binding and incontestable and may be used as a
basis for judgment thereon in any jurisdiction. The Parties hereby expressly agree to waive the right to appeal from the decision of
the arbitrator(s). Accordingly, there shall be no appeal to any court or other authority (government or private) from the decision of
the arbitrator(s), and the Parties shall not dispute nor question the validity of such decision or award before any regulatory or other
authority  in  any  jurisdiction  where  enforcement  action  is  taken  by  the  Party  in  whose  favor  the  decision  or  award  is  rendered,
except in the case of fraud. The arbitrator(s) shall, upon the request of either Party, issue a written opinion of the findings of fact
and conclusions of law and shall deliver a copy to each of the Parties. Each Party shall bear its own costs and attorneys’ fees, and
the Parties shall equally bear the fees, costs, and expenses of the arbitrator(s) and the arbitration proceedings; provided, however,
that the arbitrator(s) may exercise discretion to award costs, including attorneys’ fees, to the prevailing Party. Without limiting any
other remedies that may be available under applicable law, the arbitrator(s) shall have no authority to award provisional remedies of
any nature whatsoever, injunctive relief, or punitive, special, consequential or any other similar form of damages.

12.9.6        Notwithstanding  anything  herein  to  the  contrary,  a  Party  may  seek  a  temporary  restraining  order  or  a
preliminary  injunction  from  any  court  of  competent  jurisdiction  in  order  to  prevent  immediate  and  irreparable  injury,  loss,  or
damage on a provisional basis, pending the decision of the arbitrator(s) on the ultimate merits of any Dispute.

12.9.7    Notwithstanding anything to the contrary, any and all issues regarding the scope, construction, validity and
enforceability of one or more patents shall be determined in a court of competent jurisdiction under the local patent laws of the
jurisdictions having issued the patent or patents in question; provided that with respect to any such issues regarding a United States
patent, each Party hereby irrevocably submits to the exclusive jurisdiction of the United States Federal Court sitting in the Eastern
District  of  Virginia,  and  each  hereby  waives  the  defense  of  any  inconvenient  forum  for  the  maintenance  of  such  action  or
proceeding.

12.10    Relationship of the Parties. The relationship of LICENSOR and LICENSEE established by this Agreement is that
of independent contractors. Nothing in this Agreement shall be constructed to create any other relationship between LICENSOR
and  LICENSEE.  Neither  Party  shall  have  any  right,  power  or  authority  to  bind  the  other  Party  or  assume,  create  or  incur  any
expense, liability or obligation, express or implied, on behalf of the other Party.

12.11    Use of Names. Except as otherwise required under applicable law, and subject to Section 7.6, neither Party will use
the name of the other Party in its advertising, press releases or promotional materials without the prior written consent of such other
Party.

12.12    Notice. Any notice, report, communication, or consent required or permitted by this Agreement shall be in writing
and shall be sent (a) by prepaid registered or certified mail, return receipt requested, (b) by overnight express delivery service by an
internationally recognized courier, or (c) via confirmed facsimile or telecopy, followed within five (5) days by a copy mailed in the
preceding  manner,  addressed  to  the  other  Party  at  the  address  shown  below  or  at  such  other  address  as  such  Party  gives  written
notice hereunder. Such notice will be deemed to have been given when delivered or, if delivery is not accomplished by some fault
of the addressee, when tendered.

BACKGROUND

WHEREAS, Exela granted Codexis certain exclusive rights and licenses to Licensed Technology pursuant to that certain License
Agreement dated September 18, 2007 (the “Agreement”).

WHEREAS, Exela desires to obtain from Codexis, and Codexis is willing to grant to Exela, certain exclusive rights and licenses
under Codexis Licensed Technology (as defined below).

WHEREAS, in connection with such license grant, the Parties desire to amend certain sections of the Agreement to reflect such
license grant and the development and commercialization, by Exela, of a product covered by such Codexis Licensed Technology.

NOW THEREFORE, the Parties agree as follows:

AGREEMENT

I.    For the purposes of Article 6 (Payments, Reports and Records) and Sections 2.6 (First Commercial Sale), 2.7 (Fully Burdened
Manufacturing Cost) (including, for clarity, Exhibit A), 2.15 (Milestone Payments), 2.16 (Net Sales), 2.17 (Profit), 2.20 (Sublicense
Revenue), 8.7 (Defense of Infringement Claim), and 11.3 (Covenants of Licensor), (i) references to “LICENSEE” shall be replaced

“LICENSOR” shall be replaced with “Codexis” and Codexis hereby assumes all such rights and obligations under the foregoing
sections, and (iii) references to “Licensed Technology” shall be replaced with “Codexis Licensed Technology”.

II.    Article 2 (Definitions) of the Agreement is hereby amended as follows:

A.    The definition of “Licensed Product” as set forth in Section 2.13 is hereby deleted in its entirety and replace with the

following:

2.13    “Licensed Product” means any product that, the manufacture, use or sale of which (a) is covered by the

Licensed Patent Rights; or (b) involves the use of Licensed Know-How or Codexis Licensed Know-How.

B.    The following definitions are added:        

2.23     “Codexis Licensed Know-How” means technology, information, expertise, know-how and/or trade secrets

owned or controlled by Codexis relating to the manufacture and/or use of Licensed Product including without limitation any
Improvement owned or otherwise controlled by Codexis during the term of this Agreement.    

2.24     “Codexis Licensed Technology” means all Licensed Technology and Codexis Licensed Know-How.

III.    Article 3 (Grant) of the Agreement is hereby amended as follows:

A.    Section 3.2 (Reservation of Rights) is hereby deleted in its entirety and replaced with the following:

3.2    Reservation of Rights. Notwithstanding anything to the contrary, Codexis retains the right to use the Codexis

Licensed Technology for internal research purposes and for the benefit of Exela, including the purpose set forth in Section 5.2.2.
For purposes of clarification, (i) any Improvement discovered by Codexis as a result of such research shall be included in the
Codexis Licensed Technology and subject to the license grant set forth below in Section 3.4, and (ii) any Improvement discovered
by Exela as a result of the use of the Licensed Technology by Exela for internal research purposes for the benefit of Codexis, shall
be included in the Licensed Technology and subject to the license grant set forth in Section 3.1.

B.    The following Section 3.4 is added as follows:

3.4    License Grant Back. Effective on the Amendment Effective Date and subject to Sections 3.2 and 5.2.2,

Licensed Technology to make, have made, use, offer to sell, sell, and import Licensed Products in the Territory.

IV.    Article 5 (Development) is hereby deleted in its entirety and replaced with the following:

5.1    Efforts of Exela. Exela shall use commercially reasonable efforts to (a) develop and commercialize Licensed

Products in the United States, at Exela’s cost and expense, including without limitation causing an ANDA to be filed on Exela’s
behalf with respect to a Licensed Product, or (b) sublicense the Codexis Licensed Technology to a Third Party, such Third Party to
be reasonably acceptable to Codexis, to develop and commercialize Licensed Products in the United States. The Parties agree that
time is of the essence. Exela covenants that such Licensed Products shall be manufactured in accordance with the formulation set
forth in Exhibit C, unless Exela obtains Codexis’ prior written consent. In the event that Exela determines, in Exela’s sole
discretion, to grant a sublicense under the Codexis Licensed Technology, (i) Exela shall provide Codexis an opportunity to review
and comment upon the terms and conditions of such sublicenses, and (ii) such sublicenses shall require the sublicensee to file an
ANDA with respect to a Licensed Product. For purposes of clarification, as between the Parties, Exela shall own all Regulatory
Filings.

[***] Certain information in this document has been omitted and filed separately with the Securities and Exchange
Commission. Confidential treatment has been requested with respect to the omitted portions.

5.2    Responsibilities of Codexis.

5.2.1    Codexis shall provide to Exela or its designee copies of any and all documentation, information and materials,
including without limitation, tangible embodiments of Codexis Licensed Technology, that are within Codexis’ possession and
which Codexis has the right to provide to Exela that are necessary or useful for the manufacture of Licensed Products.

5.2.2    Codexis will use commercially reasonable efforts to conduct an in vitro study for inclusion in Exela’s 505(b)(2)

application; provided that in the event the Licensed Product available to Codexis as of the Amendment Effective Date is not
reasonably acceptable for use in such in vitro study, either prior to or after the completion of such in vitro study, the Parties will
discuss in good faith the best method of obtaining sufficient Licensed Product to enable completion of such in vitro study.

5.3    Assignment of Certain Third Party Agreements by Codexis.

5.3.1    Codexis hereby assigns to Exela all of Codexis’ rights, title and interest in and to, and obligations under,

certain third-party agreements set forth in Exhibit D (as attached to this Amendment), and Exela hereby assumes all rights, title and
interest in and to, and obligations under, such third-party agreements.

5.3.2     Codexis shall use commercially reasonable efforts to obtain the requisite consents to transfer the third-party
agreements set forth in Exhibit E (as attached to this Amendment) and upon receipt of such consents, Codexis shall assign to Exela,
and Exela shall assume, all rights, title and interest in and to, and obligations under, such third-party agreements.

5.4    Responsibilities of Exela. In the event that the practice of the license granted by Exela to Codexis under

Section 3.1 or granted by Codexis to Exela under Section 3.4 is found by a court of competent jurisdiction to infringe any
intellectual property rights of any Third Party, Exela shall use its best efforts, at Exela’s sole cost and expense, to develop a non-
infringing formulation for Compound and will license such formulation to Codexis under terms contained herein.

V.    Article 6 (Payments, Reports and Records) is hereby amended as follows:

Products in the Territory that are received and fully earned by Exela.

B.    Section 6.2 is hereby deleted in its entirety.

B.    The following sentence in Section 8.2:

“LICENSOR and LICENSEE shall share equally all prosecution and maintenance expenses; provided, however, that

in the event that LICENSEE funds the development of the Exhibit Batches for any Licensed Product, LICENSEE shall pay [***]
percent ([***]%) of such costs incurred after the date of ANDA filing for such Licensed Product and LICENSOR shall pay [***]
percent ([***]%) of such costs”

is hereby deleted in its entirety and replaced by the following:

“Codexis shall pay [***] percent ([***]%) of all prosecution, filing and maintenance costs and Exela shall pay [***]

percent ([***]%) of such costs.”

VII.    Article 9 (Term and Termination) is hereby amended as follows:

A.    Sections 9.2 (Termination Upon Material Breach), 9.3 (Termination by Licensee) and 9.5 (Consequences of Expiration

or Termination) are hereby deleted in their entirety and replaced with the following:

9.2     Termination Upon Material Breach.

9.2.1    Upon any breach of, or default by Exela under Sections 5.1, 5.4 or 6.1 of this Agreement (each, a “Material

Breach”), Codexis may, in addition to any other rights and remedies it may have at law or in equity, terminate the rights and
licenses granted hereunder to Exela by [***] ([***]) days written notice to Exela. Said notice shall become effective at the end of
such period unless during said period Exela cures such Material Breach (if curable).

9.2.2    Upon any other breach or default by Exela not covered under Section 9.2.1 (each, a “Non-Material Breach”),
Codexis shall notify Exela and Exela shall use commercially reasonable efforts to promptly remedy such Non-Material Breach. For
the sake of clarity, Codexis may not terminate the rights and licenses granted hereunder to Exela but reserves any other rights and
remedies it may have at law or in equity, provided that Exela demonstrates to Codexis that it has undertaken precautions to prevent
any further such Non-Material Breaches.

[***] Certain information in this document has been omitted and filed separately with the Securities and Exchange
Commission. Confidential treatment has been requested with respect to the omitted portions.

9.3    Termination by Exela. Exela shall have the right to terminate the rights and licenses granted to each Party

pursuant to this Amendment at any time upon [***] ([***]) days written notice to Codexis in the event that (a) the
commercialization of any Licensed Product by Exela creates a conflict with any of Exela’s partners, or (b) Exela makes a good faith
determination that any Licensed Product is not suitable for commercial use, where "not suitable for commercial use" means, for
example, that such Licensed Product is not safe, not effective, unstable, impure, fails to scale up, fails analytical validation or fails
to have suitable shelf life; provided that such unsuitability is not caused by the API supplied by Exela.

9.5     Consequences of Expiration or Termination. Upon expiration of this Agreement in accordance with Section
9.1, but not early termination, the rights and licenses granted by Codexis to Exela pursuant to Article 3 shall become fully paid-up,
royalty-free and irrevocable. In the event of termination of this Agreement, each Party shall promptly return, or at the other Party’s
request destroy, any Confidential Information of the other Party in such Party’s possession or control at the time of termination. In
the case of termination (a) by Codexis pursuant to Section 9.2, or (b) by Exela pursuant to Section 9.3, the rights and licenses
granted hereunder to Exela shall terminate, and for the avoidance of doubt, the rights and licenses granted under the Agreement to
Codexis shall remain in full force and effect. In the case of termination by Codexis pursuant to Section 9.2, Exela shall supply
Codexis with API for any Licensed Product at a transfer price equal to the [***] for such API plus [***] percent ([***]%);
provided that a court of competent jurisdiction has not held that the Licensed Technology infringes the intellectual property rights
of any Third Party; provided further that such supply does not conflict with any contractual obligations of Exela. In the event of any
termination of this Agreement, (i) any sublicense granted by Exela prior to the effective date of such termination shall survive such
termination, and (ii) all sublicense royalties or other sublicense-related consideration that the sublicense would have owed to Exela
under such sublicense shall be paid by such sublicensee to Codexis.

B.    Section 9.4 (Termination by Licensor) is hereby deleted in its entirety.

VIII.    Except to the extent amended by this Amendment, all of the definitions, terms, provision and conditions of the Agreement
shall remain in full force and effect. The Agreement and this Amendment shall be read and construed together as a single
agreement.

IX.    This Amendment may be executed in counterparts, each of which shall be deemed an original and all of which together shall
constitute one instrument.

[***] Certain information in this document has been omitted and filed separately with the Securities and Exchange

Mark Ho
[ADDRESS]

Dear Mark:

On behalf of Codexis, I am pleased to extend to you this offer of employment as
Director of Technical Accounting & Reporting, this position will report to Brian Dowd. Your position is a full-time position.

Your employment is subject to proof of your legal right to work in the United States, and to your completing the United States Citizenship and
Immigration  Service  Employment  Eligibility  Verification  Form  I-9.  Your  employment  is  also  subject  to  successful  verification  of  your
professional and character references.

Compensation

If  you  accept  this  offer  and  you  begin  employment  with  Codexis,  you  will  receive  an  initial  salary  of  $165,000.00  per  year,  payable  semi-
monthly.

You will also be eligible to participate in the Codexis Employee Incentive Compensation Plan. Your incentive plan target will be 20% of your
base  salary.    If  Codexis  meets  all  of  its  corporate  goals  for  2009,  and  you  also  perform  well  against  your  individual  and  group  goals,  to  be
established with your supervisor, you can expect to receive an incentive plan payment at or near this target after our Board’s approval of our
2009 year-end financial statements.  Naturally, based on the Company’s performance and your individual and group’s goal performance, your
actual  bonus  may  be  more  or  less  than  this  target.  Any  incentive  plan  payment  you  receive  under  this  plan  will  be  prorated  based  on  your
service during 2009 as a percentage of the full year; and no bonus will be paid unless you are an employee of the Company on the date the
bonus is paid.  Please also note that this Plan does not constitute a contract of employment or alter the “at will” status of your employment.

You will also receive a sign-on bonus of $8,000.00, which will be paid out in your first pay check. If you choose to resign employment within a
year, you will be required to repay this sign-on bonus, as follows:

a) within three months of your date of hire: 100%
b) between three and twelve months: prorated monthly.

Stock Options

    
Codexis, Inc.

Tel: 650.421.8100 
Fax: 650.421-8135 
www.codexis.com

Subject to approval by the Codexis Board of Directors, you will be granted an option to purchase 15,000 shares of stock at an exercise price
equal to the fair market value of the shares on the date the option is granted. The shares subject to the Option will vest one fourth or 25% on the
first  anniversary  of  your  employment  start  date  and  thereafter  will  vest  as  to  1/48  of  the  shares  subject  to  the  Option  per  month  for  the
following 36 months until the option is 100% vested. Your stock options will be subject to the terms of the Codexis Inc. 2002 Stock Plan and
will be conditioned on your acceptance of an appropriate stock option agreement.

Employee Benefits

As a full time employee, you will be eligible for the Codexis employee benefit plans, including medical, dental, vision, long and short-term
disability  plans,  life  insurance,  a  401(k)  savings  plan,  and  our  flexible  time  off  plan  that  allows  full  time  employees  to  accrue  20  days  of
flexible time off each year of employment.

Other Terms and Conditions of Employment

All employment with Codexis is at will. “Employment at will” means that you are free to resign from your employment at any time, for any
reason or no reason at all, with or without cause and with or without notice. Similarly, Codexis may terminate your employment at any time for
any legal reason, with or without cause and with or without notice. By accepting this offer of employment, you agree that your employment is
at  will,  and  acknowledge  that  no  one,  other  than  the  President  of  Codexis  or  the  Chairman  of  the  Board  of  Directors  of  Codexis,  has  the
authority to promise you, either orally or in writing, anything to the contrary. Any such agreement must be in writing and signed by both you
and such individual to be effective.

Employment with any other entity or for yourself in competition with Codexis, or subsidiary of Codexis is not permitted. If you want to take an
outside job, you should discuss the outside opportunity with your manager and the Human Resources Department in advance so that we can
determine if any actual or potential conflict of interest exists.

During the course of your employment, you may create, develop or have access to confidential information belonging to Codexis, including
trade  secrets  and  proprietary  information,  such  as  technical  and  scientific  research  and/or  protocols,  customer  and  supplier  information,
business  plans,  marketing  plans,  unpublished  financial  information,  designs,  drawings,  innovations,  inventions,  discoveries,  specifications,
software, source codes, and personnel information. You agree that as a condition of your employment with Codexis, you will sign and comply
with the Codexis Confidential Information, Secrecy and Invention Agreement.

Arbitration of Disputes

You agree that, except as described below, any dispute relating to your employment or the termination of your employment with Codexis shall
be finally settled by binding arbitration in Palo Alto, California before a neutral arbitrator of the American Arbitration Association (“AAA”)

Codexis, Inc. 
200 Penobscot Drive 
Redwood City, CA 94063 
Tel: 650.421.8100 
Fax: 650.421-8135 
www.codexis.com

under its National Rules for the Resolution of Employment Disputes. Claims subject to arbitration shall include, but shall not be limited to,
claims under Title VII of the Civil Rights Act of 1964 (as amended) and other civil rights statutes of the United States, the Age Discrimination
in Employment Act, the Americans with Disabilities Act, the Family and Medical Leave Act, the Employee Retirement Income Security Act of
1974, the California Fair Employment and Housing Act, the California Labor Code, and any other federal, state or local statute or regulation,
and the common law of contract and tort. However, this agreement to arbitrate shall not apply to claims (a) for workers’ compensation, (b) for
unemployment compensation or (c) injunctive relief arising out of or related to misappropriation of trade secrets or misuse or improper
disclosure of confidential information, unfair competition or breach of any non-competition or non-solicitation agreement between you and
Codexis.

You understand that by this agreement, you and Codexis are waiving your respective rights to trial by jury, and that judgment upon any
arbitration award may be entered in any court having jurisdiction of the matter. Any controversy or claim subject to arbitration shall be waived
and forever barred if arbitration is not initiated within one year after the date the controversy or claim first arose, or if statutory rights are
involved, within the time limit established by the applicable statute of limitations.

With regard to statutory claims, you and Codexis will have the same remedies available in arbitration as those available had the claim been
filed in a court of law, including, where authorized by statute, compensatory and punitive damages, injunctive relief and attorneys’ fees.
Although Codexis will pay all costs of the AAA and the arbitrator, you agree to pay all costs you would otherwise be required to pay were your
claims litigated in a court of law, such as costs of your attorney, deposition transcripts and expert witness fees and expenses.

The terms described in this letter replace all prior agreements, understandings, and promises between Codexis and you concerning the terms
and conditions of your employment with Codexis.

Mark, we hope that your association with Codexis will be mutually successful and rewarding, and we look forward to welcoming you aboard.
Please indicate your acceptance of this offer by signing this letter below and returning the letter to Human Resources by 8/21/2009. A copy of
the letter is enclosed for your records.

Sincerely,

Codexis, Inc.
