segment is focused on developing unique technical and operational capabilities designed to enable the production and commercialization of biofuels, in particular ethanol from cellulosic biomass. Its specialty enzymes business segment develops
customized enzymes for use within the alternative fuels, specialty industrial processes, and animal nutrition and health markets to enable higher throughput, lower costs, and improved environmental outcomes.

Recent Developments

As more fully described
in Note 12, on July 1, 2009, the Company entered into agreements to amend the remaining $29.5 million outstanding of its 8% Senior Convertible Notes. The amendments became effective on July 6, 2009.

Basis of Presentation

The accompanying
unaudited condensed consolidated financial statements have been prepared in accordance with U.S. generally accepted accounting principles for interim financial information. Accordingly, they do not include all the information and footnotes required
by U.S. generally accepted accounting principles for complete financial statements. In the opinion of management, all adjustments, consisting of normal recurring accruals, which are necessary for a fair presentation of the results of the interim
periods presented, have been included. The results of operations for the interim periods are not necessarily indicative of results to be expected for any other interim period or for the year as a whole. These unaudited condensed consolidated
financial statements and footnotes thereto should be read in conjunction with the audited financial statements and footnotes thereto contained in the Companys Annual Report on Form 10-K and Form 10-K/A for the year ended December 31, 2008
filed with the Securities and Exchange Commission (SEC) on March 16, 2009 and April 30, 2009.

The Company has a
working capital deficit of $16.8 million and an accumulated deficit of $630.2 million as of June 30, 2009. Based on the Companys operating plan, which includes payments to be received by the Company or its consolidated entities from BP
Biofuels North America LLC (BP) relating to the first and second phases of the strategic partnership, its existing working capital may not be sufficient to meet the cash requirements to fund the Companys planned operating expenses,
capital expenditures, required and potential payments under the 2007 Notes and the 2008 Notes, and working capital requirements beyond 2009 without additional sources of cash and/or the deferral, reduction or elimination of significant planned
expenditures.

These factors raise substantial doubt about the Companys ability to continue as a going concern. The accompanying
condensed consolidated financial statements have been prepared assuming that the Company will continue as a going concern. This basis of accounting contemplates the recovery of the Companys assets and the satisfaction of liabilities in the
normal course of business.

The Company plans to address the expected shortfall of working capital beyond 2009 by generating additional
financing through a combination of corporate partnerships and collaborations, federal, state and local grant funding, selling and financing of assets, incremental product sales, and if necessary and available, the sale of debt or equity securities.
If the Company is unsuccessful in raising additional capital from any of these sources, it will defer, reduce, or eliminate certain planned expenditures. The Company will continue to consider other financing alternatives. There can be no assurance
that the Company will be able to obtain any sources of financing on acceptable terms, or at all.

If the Company cannot obtain sufficient
additional financing in the short-term, it may be forced to restructure or significantly curtail its operations, file for bankruptcy or cease operations. The condensed consolidated financial statements do not include any adjustments relating to the
recoverability and classification of recorded asset amounts and classification of liabilities that might be necessary should the Company be forced to take any such actions.

Basis of Consolidation

The condensed consolidated financial statements include the accounts of the Company and its wholly-owned subsidiaries, including Verenium Biofuels Corporation, as well as Galaxy Biofuels LLC (Galaxy), and
Vercipia Biofuels LLC (formerly Highlands Ethanol LLC) (Vercipia) both determined to be variable interest entities of which the Company is the primary beneficiary as defined by Financial Interpretation 46R Consolidation of
Variable Interest Entities (FIN 46R). As of June 30, 2009, Vercipia had total assets of $5.3 million included in the Companys condensed consolidated financial statements of which $4.9 million was cash and cash
equivalents to be used solely for this entity and is included in the Companys consolidated cash and cash equivalents. As of June 30, 2009, Galaxy assets did not have a carrying value. All intercompany accounts have been eliminated in
consolidation.

Use of Estimates

The preparation of financial statements in conformity with U.S. generally accepted accounting principles requires management to make estimates and judgments that affect the reported amounts of assets, liabilities, revenue and expenses, and
related disclosures. On an ongoing basis, the Company evaluates these estimates, including those related to revenue recognition, long-lived assets, accrued liabilities, its convertible senior notes and income taxes. These estimates are based on
historical experience, on information received from third parties, and on various other assumptions that are believed to be reasonable under the circumstances, the results of which form the basis for making judgments about the carrying values of
assets and liabilities that are not readily apparent from other sources. Actual results may differ from these estimates under different assumptions or conditions.

Adopted Accounting Pronouncements

On January 1, 2009, the Company adopted APB 14-1, which clarifies the
accounting for convertible debt instruments. The adoption of APB 14-1 affects the accounting for our 8% Senior Convertible Notes issued in February 2008 and due April 1, 2012 (2008 Notes). APB 14-1 requires the Company to account
separately for the liability and equity components of the convertible debt in a manner that reflects the Companys nonconvertible debt (unsecured debt) borrowing rate when interest expense is recognized. APB 14-1 requires bifurcation of a
component of the debt, classification of that component in equity and the accretion of the resulting discount on the debt to be recognized as part of interest expense in the Condensed Consolidated Statement of Operations.

APB 14-1 required retroactive application to the terms of instruments as they existed for all periods presented. The following table sets forth the
effect of the retrospective application of APB 14-1 on certain previously reported line items (in thousands, except per share data):

|(4) | Represents the reclassification of debt issuance costs of $2.1 million related to the equity component (conversion option) to additional paid-in capital in stockholders
equity, partially offset by a decrease in amortization and write-off of debt discount to interest expense upon conversions aggregating approximately $12.1 million in face value due to lower issuance costs related to the debt component.

component.

|(7) | Represents the decrease in non-cash interest expense due to the change in accounting for conversions under APB 14-1. During 2008, in accordance with Emerging Issues Task Force
(EITF) 00-27, Application of Issue 98-5 to certain Convertible Instruments (EITF 00-27), unamortized debt discounts and debt issuance costs upon conversion were written off to interest expense. Under APB 14-1
conversions are accounted for as gains or losses on debt extinguishment which is accounted for as the difference between the fair value of the debt liability and the carrying value on conversion (principal less unamortized discounts and debt
issuance costs).

Additionally, on January 1, 2009, the Company adopted EITF 07-5, Determining Whether an
Instrument (or Embedded Feature) is Indexed to an Entitys Own Stock(EITF 07-5). EITF 07-5 provides that an entity should use a two-step approach to evaluate whether an equity-linked financial instrument (or embedded
feature) is indexed to its own stock, including evaluating the instruments contingent exercise and settlement provisions. The adoption of this pronouncement required the Company to perform additional analysis on both its freestanding equity
derivatives and embedded equity derivative features. The adoption of EITF 07-05 revised the Companys accounting for the 2008 Notes conversion rights, resulting in the Company recording a derivative liability of $13.1 million representing the
fair value of the conversion rights as of January 1, 2009. The recording of the derivative liability resulted in the reclassification of the equity component included in stockholders equity recorded from the adoption of APB 14-1. EITF
07-5 requires the Company to recognize the cumulative effect of the change in accounting principle as an adjustment to the opening balance of retained earnings.

The cumulative adjustment to accumulated deficit related to the 2008 Notes was $5.4 million, which represents the gains on remeasurement that would have been recognized if the guidance in EITF 07-5 had been applied
from the issuance date on February 27, 2008.

Long-Lived Assets

Long-lived assets are reviewed for impairment whenever events or changes in circumstances indicate that the carrying amount of the assets might not be
recoverable. Conditions that would necessitate an impairment assessment include a significant decline in the observable market value of an asset, a significant change in the extent or manner in which an asset is used, or a significant adverse change
that would indicate that the carrying amount of an asset or group of assets is not recoverable. For long-lived assets to be held and used, the Company recognizes an impairment loss only if its carrying amount is not recoverable through its
undiscounted cash flows and measures the impairment loss based on the difference between the carrying amount and fair value.

Derivative Financial
Instruments

The Companys 2008 Notes (See Note 2) have been accounted for in accordance with Statement of Financial
Accounting Standards (SFAS) No. 133, Accounting for Derivative Instruments and Hedging Activities (SFAS 133) and EITF No. 00-19, Accounting for Derivative Financial Instruments Indexed to, and
Potentially settled in a Companys own Stock (EITF 00-19), EITF 07-5, and SFAS 150, Accounting for Certain Financial Instruments with Characteristics of Both Liabilities and Equity (SFAS
150).

For derivative instruments that are required to be accounted for as assets or liabilities, the instrument is
initially recorded at its fair value and then at each reporting date, the change in fair value is recorded in the statement of operations.

Fair
Value Measurements

In September 2006, the FASB issued SFAS No. 157,Fair Value Measurements
(SFAS 157) which defines fair value, establishes a framework for measuring fair value and expands the disclosure requirements regarding fair value measurements. SFAS 157 was effective for fiscal years beginning after November 15,
2007 for financial assets and liabilities as well as for non-financial assets and liabilities that are recognized or disclosed at fair value on a recurring basis in the financial statements. In accordance with FSP No. 157-2,Effective Date
of FASB Statement No. 157 (FSP 157-2), for all other non-financial assets and liabilities, SFAS 157 was effective for fiscal years beginning after November 15, 2008. In October 2008, the FASB issued FSP
No. 157-3, Determining the Fair Value of a Financial Asset When the Market for That Asset is Not Active (FSP 157-3), that clarifies the application of SFAS 157 for financial assets in a market that is not active and
addresses key considerations in determining the fair value of a financial asset when the market for that financial asset is not active.

##### Table of Contents

On January 1, 2009, in accordance with FSP 157-2, the Company adopted the provisions of SFAS 157 on
a prospective basis for its non-financial assets and liabilities that are not recognized or disclosed at fair value on a recurring basis. SFAS 157 requires that the Company determine the fair value of financial and non-financial assets and
liabilities using the fair value hierarchy established in SFAS 157 and describes three levels of inputs that may be used to measure fair value, as follows:

Level 1Quoted prices in active markets for identical assets or liabilities.

Level 2Inputs other than Level 1 that are observable, either directly or indirectly, such as quoted prices for similar assets or liabilities; quoted prices in markets that are not active; or other inputs that are observable
or can be corroborated by observable market data for substantially the full term of the assets or liabilities.

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.

Classification within the hierarchy is determined based on the lowest level of input that is significant to the fair value measurement.

The adoption of SFAS 157 for the Companys non-financial assets and liabilities that are not recognized or disclosed at fair value on a recurring basis had no effect on consolidated net income for the three and
six months ended June 30, 2009.

The following table summarizes, for each major category of assets or liabilities, the respective fair
value and the classification by level of input within the fair value hierarchy defined in SFAS 157 (in thousands):

|(4) | Represents the compound embedded derivative included in the Companys 2008 Notes (see Note 2). The compound embedded derivative includes, among other rights, the
noteholders right to receive make-whole amounts. The make-whole provision provides that, upon any noteholders conversion of the 2008 Notes for common stock, the Company is obligated to pay such holder an amount in
cash or, subject to certain limitations, shares of common stock equal in value to the interest foregone over the life of the 2008 Notes as a result of such conversion, discounted back to the date of conversion using the published yield on two-year
U.S. Treasury notes as the discount rate, and, if applicable, valuing the shares of stock at a 5% discount to the applicable stock price at the time of conversion. The Companys lattice valuation model assumes the noteholders
exercise patterns will follow risk-neutral conversion behavior throughout the term of the instrument consistent with maximizing the expected present value of the 2008 Notes. Because the maximizing condition reflects the expected present value of the
2008 Notes as a whole and not the make-whole amount, the fair value of the compound embedded derivative does not reflect the maximum potential obligation due under the make-whole provision. As such, the potential
make-whole obligation was $7.0 million if all of the outstanding 2008 Notes as of June 30, 2009 converted at that time. The compound embedded derivative is included in current liabilities on the accompanying Condensed Consolidated
Balance Sheet.

|(1) | The detachable warrants, compound embedded derivative and convertible hedge transaction are revalued at the end of each reporting period and the resulting difference is included in
the results of operations. The fair value of the compound embedded derivative, detachable warrants and convertible hedge transaction are primarily affected by the Companys stock price, but are also affected by the Companys stock
price volatility, expected life, interest rates and the passage of time as it relates to the make-whole amount. For the six months ended June 30, 2009, the net adjustment to fair value resulted in a gain of $3.4 million and is
included in gain (loss) on net change in fair value of derivative assets and liabilities on the accompanying Condensed Consolidated Statement of Operations (see Note 2).

be recorded as a derivative liability, partially offset by make-whole payments related to the conversion of $10.1 million in face value of the 2008 Notes. (see Note 2)
|--- | ---------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------

Revenue Recognition

The Company recognizes revenue in accordance with Securities and Exchange Commission Staff Accounting Bulletin (SAB) 104, Revenue Recognition (SAB 104), EITF 00-21, Accounting for
Revenue Arrangements with Multiple Deliverables (EITF 00-21) and EITF 99-19, Gross versus Net Presentation of Revenue (EITF 99-19).

Under SAB 104, revenue is recognized when the following criteria have been met: i) persuasive evidence of an arrangement exists; ii) services have been
rendered or product has been delivered; iii) price to the customer is fixed and determinable; and iv) collection of the underlying receivable is reasonably assured.

Billings to customers or payments received from customers are included in deferred revenue on the balance sheet until all revenue recognition criteria are met. As of June 30, 2009, the Company had $3.6 million in
deferred revenue, of which $3.1 million was related to funding from collaborative partners and $0.5 million was related to product sales.

Product Revenue

The Company recognizes product revenue at the time of shipment to the customer, provided all other revenue
recognition criteria have been met. The Company recognizes revenue on product sales through third-party distribution agreements, if the distributor has a right of return, in accordance with the provisions set forth in SFAS 48, Revenue
Recognition When Right of Return Exists (SFAS 48). Under SFAS 48, the Company recognizes product revenues upon shipment to distributors, provided that (i) the price is substantially fixed and determinable at the time of
sale; (ii) the distributors obligation to pay the Company is not contingent upon resale of the products; (iii) title and risk of loss passes to the distributor at time of shipment; (iv) the distributor has economic substance
apart from that provided by the Company; (v) the Company has no significant obligation to the distributor to bring about resale of the products; and (vi) future returns can be reasonably estimated. For any sales that do not meet all of the
above criteria, revenue is deferred until all such criteria have been met.

The Company recognizes product profit-sharing revenue during
the quarter in which such revenue is earned, generally upon shipment of product to the end user, based on information provided by the Companys profit-sharing partner. Profit-sharing revenue is included in product revenue in the Condensed
Consolidated Statement of Operations.

The Company has contracted with Genencor, a subsidiary of Danisco, to serve as a second-source
manufacturer of Phyzyme. Under EITF 99-19, revenue assoicated with product manufactured for the Company by Genencor is recognized on a net basis equal to the net profit share received from Danisco, as all the following conditions of reporting net
are met: i) the third party is the obligor; ii) the amount earned is fixed; and iii) the third party maintains inventory risk. The Company records revenue equal to the full value of the manufacturing costs plus profit share for Phyzyme it
manufactures through its contract manufacturing agreement with Fermic S.A. in Mexico City.

Collaborative Revenue

The Company recognizes revenue from research funding under collaboration agreements when earned on a proportional performance basis as research hours are incurred. The Company performs services as
specified in each respective agreement on a best-efforts basis, and is reimbursed based on labor hours incurred on each contract. The Company initially defers revenue for any amounts billed or payments received in advance of the services being
performed and recognizes revenue pursuant to the related pattern of performance, based on total labor hours incurred relative to total labor hours estimated under the contract.

The Company recognizes fees received to initiate research projects over the life of the project. The Company recognizes fees received for exclusivity in
a field over the period of exclusivity.

The Company recognizes milestone payments when earned, as evidenced by written acknowledgement
from the collaborator, provided that (i) the milestone event is substantive and its achievability was not reasonably assured at the inception of the agreement, (ii) the milestone represents the culmination of an earnings process,
(iii) the milestone payment is non-refundable and (iv) the Companys past research and development services, as well as its ongoing commitment to provide research and development services under the collaboration, are charged at fees
that are comparable to the fees that the Company customarily charges for similar research and development services.

Grant Revenue

The Company recognizes revenue from grants as related costs are incurred, as long as such costs are within the funding limits specified by
the underlying grant agreements.

Revenue Arrangements with Multiple Deliverables

The Company sometimes enters into revenue arrangements that contain multiple deliverables in accordance with EITF 00-21. This issue addresses the timing
and method of revenue recognition for revenue arrangements that include the delivery of more than one product or service. In these cases, the Company recognizes revenue from each element of the arrangement as long as separate value for each element
can be determined, the Company has completed its obligation to deliver or perform on that element, and collection of the resulting receivable is reasonably assured.

Variable Interest Entities

The Company has implemented the provisions of FIN 46R, which
addresses consolidation by business enterprises of variable interest entities either: (1) that do not have sufficient equity investment at risk to permit the entity to finance its activities without additional subordinated financial support, or
(2) in which the equity investors lack an essential characteristic of a controlling financial interest.

As more fully described in
Note 4, the Company and BP have entered into a strategic collaboration which includes two special purpose entities, Galaxy and Vercipia, both of which are jointly owned by BP and the Company.

The Company has determined, pursuant to FIN 46R, that both Galaxy and Vercipia qualify as variable interest entities and that Verenium is the primary
beneficiary of both entities. Because the Company is the primary beneficiary, Galaxy and Vercipia are therefore subject to consolidation by the Company. As a result, BPs capital contributions are recorded as Noncontrolling interests in
consolidated entities on the Companys Condensed Consolidated Balance Sheet. The Company consolidates the operating results of Galaxy and Vercipia, and records an adjustment to the Noncontrolling interests in consolidated
entities for BPs share of profits and/or losses in these entities.

On January 1, 2009, the Company adopted SFAS 160,
Noncontrolling Interests in Consolidated Financial Statements (SFAS 160). This statement recharacterizes the accounting and reporting for minority interests as noncontrolling interests and classifies them as a
component of stockholders equity. Although the adoption of SFAS 160 did not impact the Companys results of operations and financial position, SFAS 160 required the Company to reclassify noncontrolling interests as stockholders
equity, include the net loss attributable to noncontrolling interests as part of the Companys consolidated net loss and provide additional disclosures as part of our financial statements. As required by SFAS 160, the Company implemented the
presentation and disclosure requirements of this new standard retrospectively to all periods presented.

The following table presents the
changes in stockholders equity attributed to noncontrolling interests in consolidated entities for the three and six months ended June 30, 2009 (in thousands):



|                           |  |   |        |

|Balance at June 30, 2009   |  | $ | 36,205 |  
|                           |  |   |        |  

As of June 30, 2009, the Company had total assets of $5.3 million pertaining to Vercipia included
in the Companys Condensed Consolidated Balance Sheets. As of June 30, 2009, Galaxy assets did not have a carrying value.

Computation of Net
Loss per Share

The Company computes basic and diluted net loss per share in accordance with SFAS No. 128, Earnings
per Share (SFAS 128). Basic net loss per share is calculated by dividing net loss by the weighted average number of common shares outstanding during the period. The Company had 0.2 million and 0.3 million unvested
restricted shares outstanding as of June 30, 2009 and 2008. Additionally, pursuant to the merger agreement with Celunol, 1.5 million shares of the Companys common stock issued to former Celunol stockholders were placed in an escrow
account until June 20, 2008 to satisfy the indemnification obligation of Celunol for breaches of the representations and warranties contained in the merger agreement or any legal proceedings related thereto. On June 20, 2008, these shares
were released to the former Celunol stockholders.

For purposes of the computation of net loss per share, the unvested restricted shares
and the shares held in escrow are considered contingently returnable shares under SFAS 128 and are not considered outstanding common shares for purposes of computing net loss per share until all necessary conditions are met that no longer cause the
shares to be contingently returnable. The impact of these contingently returnable shares on weighted average shares outstanding has been excluded for purposes of computing net loss per share.

The Company has excluded all common stock equivalent shares issuable upon exercise or conversion
of outstanding stock options, warrants and convertible debt from the calculation of diluted net loss per share because all such securities are anti-dilutive for all applicable periods presented.

2007 Convertible Notes

In March and April 2007, the Company completed an offering of $120 million aggregate principal amount of 5.5% Convertible Senior Notes due April 1,
2027 (the 2007 Notes) in a private placement. The 2007 Notes have been registered under the Securities Act of 1933, as amended, to permit registered resale of the 2007 Notes and of the common stock issuable upon conversion of the 2007
Notes. As more fully described below, $18.5 million in face value of the 2007 Notes were exchanged for new debt pursuant to the Companys issuance of its 2008 Notes. As of June 30, 2009, the Company had $99.5 million in face value
outstanding under the 2007 Notes.

The 2007 Notes bear interest at 5.5% per year, payable in cash semi-annually, and are convertible
at the option of the holders at any time prior to maturity, redemption or repurchase into shares of the Companys common stock at a conversion rate of 156.5 shares per $1,000 principal amount of 2007 Notes (subject to adjustment in certain
circumstances), which represents a conversion price of $6.40 per share. The total common shares that would be issued assuming conversion of the entire $99.5 million in 2007 Notes is 15.5 million shares.

On or after April 5, 2012, the Company may, at its option, redeem the 2007 Notes, in whole or in part, for cash at a redemption price equal to 100%
of the principal amount of the 2007 Notes to be redeemed plus any accrued and unpaid interest to the redemption date. On each of April 1, 2012, April 1, 2017 and April 1, 2022, holders may require the Company to purchase all or a
portion of their 2007 Notes at a purchase price in cash equal to 100% of the principal amount of the 2007 Notes to be purchased plus any accrued and unpaid interest to the purchase date. Holders may also require the Company to repurchase all or a
portion of their 2007 Notes upon a fundamental change at a repurchase price in cash equal to 100% of the principal amount of 2007 Notes to be repurchased plus any

accrued and unpaid interest to the repurchase date. Pursuant to the terms of the 2007 Notes, a fundamental change is broadly defined as 1) a
change in control, or 2) a termination of trading of the Companys common stock.

In connection with the 2007 Notes offering, the
Company paid $5.2 million in financing charges, which is reflected in other long term assets on the accompanying Condensed Consolidated Balance Sheets, and is being amortized to interest expense over the initial five-year term of the 2007 Notes
using the effective interest method.

2008 Convertible Notes

On February 27, 2008, the Company completed a private placement of 8% Senior Convertible Notes due April 1, 2012 (the 2008 Notes) and warrants to purchase shares of Verenium common stock.
Concurrent with entering into the purchase agreement for the 2008 Notes, the Company also entered into senior notes exchange agreements with certain existing holders of the 2007 Notes pursuant to which such noteholders exchanged approximately $18.5
million in aggregate principal amount of the 2007 Notes for approximately $16.7 million in aggregate principal amount of the 2008 Notes and for warrants to purchase common stock. Including the 2008 Notes issued in exchange for the 2007 Notes, the
Company issued $71.0 million in aggregate principal amount of the 2008 Notes and warrants to purchase approximately 8.0 million shares of common stock. As of June 30, 2009, the outstanding principal balance on the 2008 Notes was $29.5
million. As described below in Note 12, on July 1, 2009, the Company entered into agreements to amend the 2008 Notes The amendments became effective on July 6, 2009.

Periodic interest payments on the 2008 Notes are approximately $0.6 million every three months, assuming an outstanding balance of $29.5 million, payable
on January 1, April 1, July 1 and October 1, of each year. Subject to the satisfaction of certain conditions, the Company may pay interest amounts with shares of common stock at a 5% discount to the applicable stock
price at the time of the interest payment.

In connection with the amendment described in Note 12, the conversion price for the 2008
Notes was reduced from $2.13 to $1.74 and the anti-dilution protection included in the 2008 Notes was changed from full ratchet anti-dilution protection to, in most cases, a version of broad-based weighted average anti-dilution protection, subject
to certain limitations. The 2008 Notes are subject to automatic conversion at the Companys option if the Companys closing stock price exceeds $3.48 (formerly $8.18 prior to the amendment described in Note12) per share over a
30-trading day period ending prior to the date the Company provides notice of the automatic conversion to investors, the average daily trading volume of the Companys stock over that 30-trading day period equals or exceeds $3 million, and
certain other conditions are met.

The 2008 Notes contain several embedded features, which are required to be bifurcated and accounted
separately as derivative liabilities in accordance with SFAS 133 and SFAS 150. These embedded features are described in two categories: 1) detachable warrants; and 2) a compound embedded derivative, as set forth below.

Detachable Warrants. In connection with the 2008 Notes, the Company issued warrants to purchase up to approximately 8 million shares of the
Companys common stock. The warrants are exercisable six months following initial issuance at an initial exercise price of $4.44 per share. The exercise price and the number of shares of the Companys common stock issuable upon exercise of
the warrants are subject to weighted average anti-dilution protection.

Compound embedded derivative. The compound embedded
derivative includes certain features of the 2008 Notes, with its major components consisting of; 1) the base conversion rights, including the full-ratchet antidilution provisions (which as described in Note 12 were recently amended to become,
in most cases a version of broad-based weighted average anti-dilution provisions, subject to certain limitations); 2) rights upon an event of default or change in control; and, 3) the make-whole provision.

Full-ratchet antidilution protection (recently amended, as described in Note 12, to become, in most cases, a verson of broad-based
weighted average anti-dilution protection, subject to certain limitation). In the event that the Company subsequently issues options (excluding options issued under an approved stock plan by the Board of Directors) or convertible securities or
other equity or equity-linked securities at a price-per-share which is below the current conversion price of the 2008 Notes, the holders of the 2008 Notes will be entitled to full-ratchet antidilution protection, such that the conversion
price will re-set to a price-per share equal to that of the new equity issuance.

Rights upon an event of default or change in
control. If the Company were to trigger an event of default, as defined, holders of the 2008 Notes may require the Company to redeem all or portion of the 2008 Notes at a premium to their face value. In the event of a change of control, as
defined, the conversion rate may be subject to adjustment, or the holders may require the Company to redeem all or a portion of the 2008 Notes at a premium to their face value.

Make-whole provision. The 2008 Notes also include a make-whole provision whereby, upon any holders conversion of the
2008 Notes for common stock, the Company is obligated to pay such holder an amount equal to the interest

foregone over the life of the 2008 Notes based on such conversion, discounted back to the date of conversion using the published yield on two-year U.S.
Treasury notes as the discount rate. The 2008 Notes provide that the Company may, subject to the satisfaction of certain conditions, pay interest or make-whole amounts with shares of its common stock at a 5% discount to the applicable
stock price at the time of the interest payment or conversion.

In addition, concurrent with the issuance of the 2008 Notes, the Company
entered into a convertible hedge transaction with a counterparty, which is intended to reduce the potential dilution upon conversion of the 2008 Notes. The convertible hedge transaction is composed of two separate call options. Under the first call
option, on April 1, 2012 (or earlier upon conversion of the 2008 Notes), the Company is entitled to purchase 13,288,509 shares of the Companys common stock from the counterparty at a price per share equal to the initial conversion price
of $4.09 (or a proportion of such number of shares based on the proportion of the 2008 Notes being converted). Under the second call option, on three exercise dates staggered in six month intervals beginning on October 1, 2013, the counterparty
is entitled to purchase an aggregate of 13,288,509 shares of the Companys common stock at a price per share of $5.16. The cash cost of the convertible hedge transaction was approximately $6.2 million. The convertible hedge transaction must
also be separately valued and accounted for as a derivative under SFAS 133.

Allocation of Proceeds to 2008 Notes

As previously described in Note 1, the Company adopted the provisions of APB 14-1 on January 1, 2009, which required retroactive restatement
of the financial statements related to the 2008 Notes at inception. This change in accounting treatment impacted the initial allocation of debt proceeds. The following table sets forth the initial allocation of proceeds from the 2008 Notes among the
underlying debt instrument, conversion rights, and the detachable warrants, as originally reported, and as adjusted to reflect the impact of APB 14-1 (in thousands):

Valuation of Debt Liability and Embedded Features

Debt Liability and Equity Component

Prior to the adoption of APB 14-1, the value assigned to the debt host was based on the residual value of the debt proceeds after allocating the fair value of the compound embedded derivative and detachable warrants. As a result of the
adoption of APB 14-1, as described under Note 1, the Company was required to separately account for the debt and equity components of the 2008 Notes in a manner that reflects the Companys nonconvertible debt (unsecured debt) borrowing
rate.

APB 14-1 requires that the carrying amount of the liability component be estimated by measuring the fair value of a similar
liability that does not have an associated conversion feature. As a result, the Company determined that its effective interest rate was 32.6% and, in the absence of comparable market data, determined that, given the features of the 2008 Notes, this
derived effective interest rate was a fair approximation of a market rate of interest for a similar instrument. As a result, the 32.6% rate was applied to the 2008 Notes and coupon interest to calculate the fair value of the liability component. The
difference between the cash proceeds associated with the convertible debt and the estimated fair value of the liability component is recorded as an equity component.

Detachable Warrants

At inception, as originally reported and as adjusted for the adoption of APB
14-1, the fair value of the detachable warrants of $4.7 million was separated from the debt liability and recorded as derivative liabilities which resulted in a reduction of the initial notional carrying amount of the 2008 Notes, and as unamortized
discount, which is being accreted over the term of the 2008 Notes using the effective interest method.

The derivative liability attributed
to the warrants could require cash settlement within one year from the balance sheet date since the warrants became exercisable in August 2008. Based upon this, the Company has reported the derivative liability related to the warrants as a current
liability on its Condensed Consolidated Balance Sheet. The derivative liability is marked-to-market at the end of



14

##### Table of Contents

each reporting period, with any change in value reported as a non-operating expense or income in the Condensed Consolidated Statement of Operations. The fair
value of the warrants was determined using the Black-Scholes Merton methodology.

Compound Embedded Derivative

At inception, as originally reported and as adjusted for the adoption of APB 14-1, the fair value of the compound embedded derivative of $31.1 million was
separated from the debt liability and recorded as a derivative liability which resulted in a reduction of the initial notional carrying amount of the 2008 Notes, and as unamortized discount, which is being accreted over the term of the 2008 Notes
using the effective interest method.

The derivative liability arising from the compound embedded derivative could require cash settlement
within one year of any balance sheet date under certain conditions outside of the Companys control, including, but not limited to, payments in connection with a conversion at the option of the noteholder. Furthermore, the amount of the
make-whole payment upon conversion is not indexed to the Companys stock, and therefore would not qualify as an equity instrument under EITF 00-19. Based upon this, the Company initially recorded a derivative liability related to
the holders rights to a make-whole payment upon conversion, the portion of the embedded conversion rights that may be settled in cash due to the certain Nasdaq limits, and a derivative liability related to certain other rights. The
Company recorded this compound embedded derivative liability as a component of the current portion of convertible debt on its Condensed Consolidated Balance Sheets. On June 4, 2008, in connection with shareholder approval of issuance of shares
in excess of certain Nasdaq limits that required shareholder approval before shares in excess of such limits could be issued, $14.7 million of the compound embedded derivative value was reclassified into stockholders equity.

However, on January 1, 2009, upon adoption of EITF 07-5, as described under Note 1, the entire conversion rights were required to be
accounted for as a derivative liability. As a result, the fair value of the conversion rights on January 1, 2009 of $13.1 million was reclassified from stockholders equity into current liabilities. The compound embedded derivative
liability, consisting of the make-whole and the conversion rights, will be marked-to-market at the end of each reporting period, with any change in value reported as a non-operating expense or income in the Condensed Consolidated
Statement of Operations. The fair value of the compound embedded derivative was determined using a lattice valuation methodology.

The Companys lattice valuation model assumes the noteholders exercise patterns will follow risk-neutral conversion behavior throughout the term of the instrument consistent with maximizing the expected present value of the 2008
Notes. Because the maximizing condition reflects the expected present value of the 2008 Notes as a whole and not the make-whole amount, the fair value of the compound embedded derivative does not reflect the maximum potential obligation
due under the make-whole provision. As such, the potential make-whole obligation is $7.0 million if all of the outstanding 2008 Notes as of June 30, 2009 converted on that date.

Valuation of Convertible Hedge Transaction

The Company recorded a derivative asset of $6.2 million, representing the net cash paid by the Company to the counterparty of the two separate call options that comprise the convertible hedge transaction. The convertible hedge transaction
does not qualify for equity classification under EITF 00-19, as there are potential circumstances, though remote, where cash settlement may be required. As such, the net fair value of the convertible hedge transaction has been reported as a
noncurrent derivative asset on the Condensed Consolidated Balance Sheets and is marked-to-market at the end of each reporting period, with any change in value reported as a non- operating expense or income in the Condensed Consolidated Statement of
Operations. The Company has determined that the initial cash paid for each of the two separate call options that comprise the convertible hedge transaction approximated fair value. The fair values of the two call options subsequent to the initial
issuance date have been determined using the Black-Scholes Merton methodology.

Impact of Fair Value Remeasurements

The fair value of the compound embedded derivative, warrants, and the two separate call options that comprise the convertible hedge transaction are
recorded as a derivative asset or liability and marked-to-market each balance sheet date. The change in fair value is recorded in the Condensed Consolidated Statement of Operations as non-operating expense or income. Upon conversion or exercise of a
derivative instrument, the instrument will be marked to fair value at the conversion date and then that fair value will be reclassified to equity if settled in the Companys common stock.

The fair value of the compound embedded derivative, detachable warrants and convertible hedge transaction are primarily affected by the Companys
stock price, but are also affected by the Companys stock price volatility, expected life, interest rates and the passage of time as it relates to the make-whole amount. For the six months ended June 30, 2009, the net change in
fair value measurements impacting all derivative assets and liabilities resulted in a gain of $3.4 million.

Loss on Exchange of Notes

In connection with the issuance of the 2008 Notes, the Company exchanged $18.5 million in aggregate principal amount of the 2007 Notes for approximately
$16.7 million in aggregate principal amount of the 2008 Notes and related warrants. Pursuant to EITF 96-19, Debtors Accounting for a Modification or Exchange of Debt Instruments (EITF 96-19), an exchange of debt
instruments with substantially different terms is a debt extinguishment and requires the recognition of a gain or loss on exchange. The Company determined that the exchange qualified as a debt extinguishment under EITF 96-19, and recorded a loss on
the exchange of $3.6 million, equal to the difference between the carrying value of the 2007 Notes and the fair value of the 2008 Notes and warrants issued.

The fair value of the 2008 Notes issued in the exchange was determined using a lattice model, consistent with the methodology used to derive the fair value of the compound embedded derivative.

Interest Expense on 2008 Notes

The Company recorded interest expense related to the 2008 Notes, as follows (in thousands):

The initial debt discount, after the adoption of APB 14-1, relates to the compound embedded
derivative, detachable warrants, and the equity component related to the conversion rights not included in the compound embedded derivative at issuance. The unamortized value of the debt discount is included in the carrying value of the 2008 Notes
on the accompanying Condensed Consolidated Balance Sheets and is being amortized into interest expense over the term of the 2008 Notes, or approximately 4 years.

Conversion of 2008 Notes

Since inception through June 30, 2009, holders of the 2008 Notes have
converted principal in the amount of $41.5 million into approximately 33.8 million shares of the Companys common stock, including approximately 17.3 million shares to satisfy a portion of the related make-whole
obligations.

Between July 1, 2009 and August 10, 2009, holders of the 2008 Notes converted an additional principal amount of
$11.3 million into approximately 10.8 million shares of the Companys common stock, including approximately 4.3 million shares to satisfy the related make-whole obligations.

During the three and six months ended June 30, 2009, in accordance with SFAS 140, Accounting for Transfers and Servicing of Financial
Assets and Extinguishment of Liabilities  A replacement of FASB Statement 125 (SFAS 140), the Company recorded a gain on conversion of $2.5 million and $6.1 million, calculated as the difference between the carrying value
of the converted 2008 Notes and the fair value of the shares of common stock delivered to the noteholders upon conversion. The carrying value of the converted 2008 Notes for the three and six months ended June 30, 2009 was equal to the $19.3
million and $29.4 million of principal less the unamortized debt discount and issuance costs, which totaled $14.4 million and $21.8 million, as of the conversion date. During the three and six months ended June 30, 2009, the Company issued a
total of 21.8 million and 30 million shares with a total market value as of the dates of conversion of $11.9 million and $15.7 million to settle the 2008 Notes that were converted and related make-whole payments.

The Company reviews inventory periodically and reduces the carrying value of items considered to
be slow moving or obsolete to their estimated net realizable value. The Company considers several factors in estimating the net realizable value, including shelf life of raw materials, demand for its enzyme products and historical write-offs.

Property and equipment

Property and equipment is stated at cost and depreciated over the estimated useful lives of the assets (generally three to ten years) using the straight-line method.

Property and equipment consist of the following (in thousands) as of:

Included in the costs of its demonstration facility as of June 30, 2009 and December 31,
2008 is $7.8 million and $6.8 million in capitalized interest, which was determined by applying the Companys effective interest rate to the average amount of accumulated expenditures for its demonstration facility. The demonstration facility
was placed in service in February 2009, and as such, the Company ceased capitalizing interest on that date.

Depreciation of property and
equipment is provided on the straight-line method over estimated useful lives as follows:



|                        |  |          
|----------------------- |  | ---------
|Laboratory equipment    |  | 3-5 years

##### Table of Contents

Leasehold improvements are amortized using the shorter of the estimated useful life or remaining lease
term.

Depreciation related to the pilot and demonstration facilities begins in the period that such assets are placed in service. The
pilot facility was placed in service in January 2007, and is being depreciated over a 10-year life. Subsequent modifications to the pilot facility which do not extend its useful life but meet the criteria for capitalization are considered
immediately placed in service when incurred, and depreciated over the remainder of the pilot facilitys useful life. The demonstration facility was placed in service in February 2009. During the three and six months ended June 30, 2009,
the demonstration facility is being depreciated using an estimated 10-year life. The Company is in the process of performing an evaluation to determine the final useful lives for the demonstration-scale facility and each of its components.

4. Strategic Partnership with BP Biofuels North America LLC

Galaxy Biofuels LLC

Effective August 1,
2008, the Company entered into a Joint Development and License Agreement (JDA) with BP focused on the development and commercialization of cellulosic ethanol technologies. As part of the transaction, Galaxy Biofuels LLC, a special
purpose entity, was formed, equally owned by the Company and BP. Pursuant to the JDA, the Company granted to Galaxy a worldwide, royalty-free license and sublicense to the Companys existing background technology related to the production of
cellulosic ethanol, which will continue to be owned by the Company. Galaxy owns new intellectual property relating to cellulosic ethanol production developed through the joint development program under the JDA and is responsible for administering
the licensing of the technology package resulting from the joint development program. Future profits and losses related to the licensing of these technologies will be shared equally by the Company and BP. The Company accounts for its investment in
Galaxy pursuant to FIN 46R, and has determined that Galaxy is subject to consolidation by the Company.

The financial terms of the JDA
include a transaction fee of $45 million paid to the Company by BP on behalf of Galaxy, in exchange for broad access to the Companys cellulosic ethanol technology platform, production facilities, and employee scientific knowledge and
expertise. The transaction fee has been paid in full and in accordance with the terms of the JDA as follows: $24.5 million was paid within ten days of the closing; $6.5 million was paid on January 2, 2009; and $14.0 million was paid on
July 1, 2009.

The Company and BP are conducting joint development efforts within the cellulosic ethanol field under the JDA, the
initial term of which is 18 months. Pursuant to the JDA, BP committed to pay the Company $45 million in non refundable joint development fees to co-fund the Companys various scientific and technical initiatives within the field. The joint
development fees represent approximately 50% of the estimated costs of these initiatives through January 2010, and are payable as follows: $15 million was paid on January 2, 2009, and $2.5 million per month is payable from February 2009 through
and including January 2010.

##### Table of Contents

The Company is responsible for the performance of substantially all of the activities under the joint
development program. If the Company is not successful in achieving the objectives of the joint development program, BP may terminate the joint development program, and the Company would no longer be entitled to receive any payments from BP for the
performance of the joint development program.

The transaction fees and joint development fees are accounted for as follows:



| |  |  | The license to technology granted by the Company and ongoing joint development performed by the Company are accounted for as capital contributions to Galaxy;
| | - |  | -------------------------------------------------------------------------------------------------------------------------------------------------------------



| |  |  | Transaction fees and joint development fees paid by BP are accounted for as capital contributions to Galaxy, which are subsequently distributed to the Company as a
reduction to the Companys capital account;
| | - |  | ---------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------



| |  |  | Ongoing joint development fees are accounted for as a monthly expense of Galaxy.
| | - |  | --------------------------------------------------------------------------------

As a result, the Companys Condensed Consolidated Balance Sheets include a line item called Noncontrolling interests in consolidated
entities, which reflects BPs ownership of Galaxys equity. This line item is adjusted by BPs 50% share of Galaxys profits and losses, and increased by cash distributions made by BP to the Company on behalf of Galaxy.
BPs share of Galaxys losses is reflected in the Condensed Consolidated Statement of Operations as Loss attributed to noncontrolling interests in consolidated entities. Since inception, Galaxy has incurred approximately $55
million in losses through June 30, 2009, 50% of which have been allocated to BP. The Company anticipates Galaxy will continue to incur losses related to ongoing joint development through at least the initial 18 months of the strategic
partnership.

Vercipia Biofuels LLC

On February 18, 2009, the Company announced the second phase of its strategic partnership with BP through the formation of a joint venture to focus on the commercial development of facilities for the production of cellulosic ethanol
from non-food feedstocks. The joint venture company, Vercipia is owned equally by the Company and BP. Vercipia will act as the commercial entity for the deployment of cellulosic ethanol technology being developed and proven under the Galaxy joint
development program. Vercipia will be led and supported by a team comprised of employees from both BP and the Company and will be governed with equal representation from both parent companies. This collaboration is intended to develop one of the
nations first commercial-scale cellulosic ethanol facilities, located in Highlands County, Florida and to create future opportunities for commercial implementation of cellulosic ethanol technologies.

The Company originally formed the Vercipia entity in October 2007 as a wholly-owned subsidiary of Verenium Corporation. The entity was fully
consolidated by the Company as a subsidiary for the years ended December 31, 2007 and 2008. BPs consideration was used to acquire a 50% ownership interest in the existing entity. The Company has determined the joint venture is a variable
interest entity, and that the Company is the primary beneficiary which requires consolidation of the entity.

In return for its 50%
interest in Vercipia, BP agreed to pay Vercipia $22.5 million in an initial cash commitment and the Company agreed to contribute development assets related to its Highlands County, Florida development project and another commercial project site in
early stages of development in the Gulf Coast region. BPs contribution is payable in four installments: $7.0 million was paid on April 1, 2009, $5.0 was paid on July 1, 2009, $3.0 million is due October 1, 2009, and $7.5 million
is due January 4, 2010. As of June 30, 2009, $4.9 million of the Companys consolidated cash and cash equivalents pertains to Vercipia and is limited for use in Vercipia operations.

Vercipia will initially focus on developing and securing financing for a commercial-scale cellulosic ethanol facility in Highlands County, Florida and
expects to break ground on that site in 2010. The estimated construction cost for this facility, which is expected to produce 36 million gallons-per-year, is estimated to be between $250 and $300 million. Production from this plant is expected
to begin in 2012.

All intercompany amounts have been properly eliminated upon consolidation, and the noncontrolling interest is presented
in accordance with SFAS 160, Noncontrolling Interests in Consolidated Financial Statements (SFAS 160), on the Companys Condensed Consolidated Balance Sheet and Statement of Operations.

5. Segment Information and Concentration of Business Risk

Segment Information

The Company operates in two segments, as defined by SFAS 131, Disclosures about
Segments of an Enterprise and Related Information (SFAS 131), identified as biofuels and specialty enzymes. The biofuels segment is focused on developing unique technical and operational capabilities designed to enable the
production and commercialization of biofuels, in particular ethanol from cellulosic biomass. The specialty enzymes segment develops high performance enzymes for use within the alternative fuels, specialty industrial processes, and animal nutrition
and health markets to enable higher throughput, lower costs, and improved environmental outcomes.

##### Table of Contents

Management assesses performance and allocates resources based on discrete financial information for the
biofuels and specialty enzymes business segments. For the biofuels segment, performance is assessed based on total operating expenses and capital expenditures. For the specialty enzymes segment, performance is assessed based on total revenues,
product revenues, product gross margin, total operating expenses and capital expenditures. For the three and six months ended June 30, 2009, the specialty enzyme segment comprised 100% of product revenues, and cost of product revenues.
Operating expenses for each segment include direct and allocated research and development and selling, general and administrative expenses. In managements evaluation of performance, certain corporate operating expenses are excluded from the
business segments such as: non-cash share-based compensation, restructuring charges, severance, depreciation and amortization, and other corporate expenses, which are not allocated to either business segment. In addition, management evaluates
segment performance based upon capital expenditures and other assets that are specifically identified to the business segment and excludes certain corporate assets that can be attributed to, or utilized by, both business segments. Expenses and
assets shared by the segments require the use of judgments and estimates in determining the allocation of expenses to the two segments. Different assumptions or allocation methods could result in materially different results by segment. Further,
expenses allocated to each of the two segments may not be indicative of the expenses of each operating segment if such segment operated on a stand-alone basis.

Selected operating results for each of the Companys business segments are set forth below (in thousands):

The facility consolidation costs are based on estimates, representing the discounted cash flow of
lease payments (net of anticipated sublease income) on the vacated space through its contractual lease term in 2016.

Pursuant to SFAS 146,
the Company is required to re-assess these estimates on a periodic basis. Accordingly, the Company may revise these estimates in future periods, which could give rise to additional charges or adjustments. For the three and six months ended
June 30, 2009, the restructuring reserve was adjusted by $190,000 and $280,000 representing the net present value adjustment for the period, for a total gross obligation of $8.4 million, net of sublease income, as of June 30, 2009.

For the three and six months ended June 30, 2009 and 2008, the adjustments and revisions related to restructuring activities were
immaterial, and are included in Selling, general and administrative expenses on the Companys Condensed Consolidated Statement of Operations.

8. Related-Party Transactions

Syngenta AG

The Company has had an ongoing research collaboration with Syngenta since 1999 and in January 2007 the Company announced a new 10-year research and development partnership with Syngenta. The new agreement, which
replaced a seven-year



22

##### Table of Contents

agreement with Syngenta that started in early 2003, is focused on the discovery and development of a range of novel enzymes to economically convert
pre-treated cellulosic biomass to mixed sugars, which is a critical step in the process of biofuel production.

The Company recognized
revenue from Syngenta and its affiliates of $16,000 and $2.9 million for the three months ended June 30, 2009 and 2008 and $32,000 and $5.2 million for the six months ended June 30, 2009 and 2008. Deferred revenue associated with Syngenta
was $0.9 million and $1.4 million at June 30, 2009 and December 31, 2008. As of June 30, 2009, Syngenta no longer is a related party of the Company.

BP

As previously noted in Note 4, the Company has a strategic partnership with BP, which has provided more
than $350 million in funding since inception. BP is committed to additional funding of more than $30 million through 2012, subject to the Companys performance under existing ventures.

9. Commitments

Letter of Credit

Pursuant to its facilities leases for office and laboratory space in San Diego, the Company is required to maintain a letter of credit on behalf of its
landlord in lieu of a cash deposit. The total amount required under the letter of credit is based on a minimum level of working capital and market capitalization.

As of June 30, 2009, the Company had a letter of credit in place pursuant to this agreement for approximately $10.4 million, representing approximately 24 months current rent, per the lease agreement. The letter
of credit is issued under the Companys existing bank agreement. The Company is required by the Bank to secure this obligation with cash, which is reflected as restricted cash on the Companys Condensed Consolidated Balance Sheets
as of June 30, 2009. Any increases to the letter of credit resulting from increases in rent or changes in working capital or market capitalization are effective upon notice to the Company by the landlord.

10. Contingencies

Class Action Shareholder Lawsuit

In June 2004, the Company executed a formal settlement agreement with the plaintiffs in a class action lawsuit filed in December 2002 in a
U.S. federal district court (the Court). This lawsuit is part of a series of related lawsuits in which similar complaints were filed by plaintiffs against hundreds of other public companies that conducted an Initial Public Offering
(IPO) of their common stock in 2000 and the late 1990s (the IPO Cases). On February 15, 2005, the Court issued a decision certifying a class action for settlement purposes and granting preliminary approval of the
settlement subject to modification of certain bar orders contemplated by the settlement. On August 31, 2005, the Court reaffirmed class certification and preliminary approval of the modified settlement. On April 24, 2006, the Court held a
Final Fairness Hearing to determine whether to grant final approval of the settlement. On December 5, 2006, the Second Circuit Court of Appeals vacated the lower Courts earlier decision certifying as class actions the six IPO Cases
designated as focus cases. The Company is not one of the six focus cases. Thereafter, the District Court ordered a stay of all proceedings in all of the IPO Cases pending the outcome of the plaintiffs petition to the Second Circuit
for rehearing en banc and resolution of the class certification issue. On April 6, 2007, the Second Circuit denied plaintiffs rehearing petition, but clarified that the plaintiffs may seek to certify a more limited class in the District
Court. Accordingly, the settlement as originally negotiated was terminated pursuant to stipulation of the parties and will not be finally approved. On or about August 14, 2007, Plaintiffs filed amended complaints in the six focus cases, and
thereafter moved for certification of the classes and appointment of lead plaintiffs and lead counsel in those cases. The six focus case issuers filed motions to dismiss the claims against them in November 2007 and an opposition to plaintiffs
motion for class certification in December 2007. The Court denied the motions to dismiss on March 16, 2008. On October 2, 2008, the plaintiffs withdrew their class certification motion. On February 25, 2009, liaison counsel for
plaintiffs informed the district court that a settlement of the IPO Cases had been agreed to in principle, subject to formal approval by the parties and preliminary and final approval by the court. On April 2, 2009, the parties submitted a
tentative settlement agreement to the court and moved for preliminary approval thereof. On June 11, 2009, the Court granted preliminary approval of the tentative settlement, ordered that notice of the settlement to be published and mailed, and
set a Final Fairness Hearing for September 10, 2009. If approved, the settlement would result in the dismissal of all claims against the Company and its officers and directors with prejudice, and the Companys pro rata share of the
settlement fund will be fully funded by insurance.

The Company is covered by a claims-made liability insurance policy which it believes
will satisfy any potential liability of the Company under this settlement. Due to the inherent uncertainties of litigation, and because the settlement has not yet been finally approved by the Court, the ultimate outcome of this matter cannot be
predicted.

Noteholder Lawsuit

On April 30, 2009, Capital Ventures International (CVI), a holder of the 2008 Notes, filed a lawsuit against the Company in the United States District Court for the Southern District of New York alleging that the Company
breached the terms of the 2008 Notes by processing certain conversion notices submitted to the Company by CVI at $2.13 (and, with the recent amendment of the



23



---

##### Table of Contents

2008 Notes, $1.74) per share, rather than $1.47 per share, asserting that CVI is entitled to additional shares based on the applicable conversions, as well
as damages, and requesting a declaratory judgment that $1.47 per share is the conversion price for the 2008 Notes. On June 3, 2009, CVI amended its complaint to also request a declaratory judgment that the Company cannot amend the 2008 Notes,
pursuant to their terms, without the consent of each affected noteholder. The Company filed its answer to CVIs amended complaint on June 30, 2009, denying all material allegations of the complaint. An initial pre-trial conference is
scheduled for August 11, 2009.

Between February 27, 2009 through August 10, 2009, the holder has converted approximately
$11.25 million in face value, and the Company has issued approximately 11.3 million shares to settle these conversions and related make-whole obligations at $2.13 or, following the recent amendment of the 2008 Notes, $1.74 per
share. Assuming a conversion price of $1.47, 1.7 million additional shares would be issuable in connection with these conversions. If the Company were to be found to have not satisfied its obligations under the 2008 Notes, because the Company
processed the applicable conversion notices at the wrong conversion price, the Company could, among other negative consequences, be required to redeem the 2008 Notes in whole or in part. The Company does not believe that this lawsuit will have a
material impact on its financial statements.

In accordance with SFAS 5, Accounting for Contingencies (SFAS
5), the Company believes any contingent liabilities related to these claims are not probable or estimable and therefore no amounts have been accrued for these matters.

In addition to the matters noted above, from time to time, the Company is subject to legal proceedings, asserted claims and investigations in the
ordinary course of business, including commercial claims, employment and other matters, which management considers to be immaterial, individually and in the aggregate. In accordance with generally accepted accounting principles, the Company makes a
provision for a liability when it is both probable that a liability has been incurred and the amount of the loss can be reasonably estimated. These provisions are reviewed at least quarterly and adjusted to reflect the impacts of negotiations,
settlements, rulings, advice of legal counsel and other information and events pertaining to a particular case. Litigation is inherently unpredictable. However, the Company believes that it has valid defenses with respect to the legal matters
pending against the Company. It is possible, nevertheless, that the Companys consolidated financial position, cash flows or results of operations could be negatively affected by an unfavorable resolution of one or more of such proceedings,
claims or investigations.

11. Impact of Recently Issued Accounting Standards

Business Combinations

On January 1, 2009 the Company adopted the provisions of FASB SFAS
No. 141(R), Business Combinations (SFAS No. 141R), which revised SFAS No. 141, Business Combinations. SFAS No. 141R establishes principles and requirements for how an acquirer
recognizes and measures in its financial statements the identifiable assets acquired, the liabilities assumed, any noncontrolling interest in the acquiree and the goodwill acquired. SFAS No. 141R also establishes disclosure requirements, which
will enable users to evaluate the nature and financial effects of business combinations. Among other things, SFAS No. 141R expands the definitions of a business and business combination, requires recognition of contingent consideration at fair
value on the acquisition date and requires acquisition-related transaction costs to be expensed as incurred. The provisions of SFAS No. 141R were applied in valuing the assets in the Vercipia joint venture. Pursuant to the provisions of SFAS
141R, since the Company is consolidating Vercipia as prescribed by FIN 46R, the assets contributed are carried on the Companys balance sheet at their respective carrying values. Accordingly, the adoption of SFAS 141R did not have a
material impact on the Companys condensed consolidated financial statements.

In April 2009, the FASB issued FSP FAS 141R-1,
Accounting for Assets Acquired and Liabilities Assumed in a Business Combination That Arise from Contingencies (FAS 14R-1). The FSP requires that assets acquired and liabilities assumed in a business combination that
arise from contingencies be recognized at fair value per SFAS No. 157, if the acquisition-date fair value can be reasonably determined. If the fair value cannot be reasonably determined, then the asset or liability should be recognized in
accordance with SFAS No. 5, and FASB Interpretation (FIN) No. 14, Reasonable Estimation of the Amount of a Loss - an interpretation of FASB Statement No. 5. The FSP also requires new disclosures for
the assets and liabilities within the scope of the FSP. The Company will apply the guidance of the FSP to business combinations completed on or after January 1, 2009.

Noncontrolling Interests in Consolidated Financial Statements

On January 1, 2009, the
Company adopted SFAS 160 which establishes accounting and reporting standards for the non-controlling interest in a subsidiary and for the deconsolidation of a subsidiary. SFAS 160 requires entities to record the acquisition of non-controlling
interests in subsidiaries initially at fair value. In accordance with the requirements of SFAS 160, the Company has provided a new presentation on the face of the consolidated financial statements to separately classify non-controlling interests
within the equity section of the consolidated balance sheets and to separately report the amounts attributable to controlling and non-controlling interests in the consolidated statements of operations, comprehensive income and changes in equity for
all periods presented. There were no changes in the Companys ownership interests in previously existing subsidiaries or deconsolidation of subsidiaries for the six months ended June 30, 2009.

Accounting for Convertible Debt Instruments

On January 1, 2009, the Company adopted APB 14-1, which clarifies the accounting for convertible debt instruments that may be settled in cash
(including partial cash settlement) upon conversion. APB 14-1 requires the Company to account separately for the liability and equity components of the convertible debt in a manner that reflects the Companys nonconvertible debt (unsecured
debt) borrowing rate when interest expense is recognized. APB 14-1 requires bifurcation of a component of the debt, classification of that component in equity and the accretion of the resulting discount on the debt to be recognized as part of
interest expense in our Condensed Consolidated Statement of Operations. See Note 1 for the impact of adoption on the Companys financial statements.

On January 1, 2009, the Company adopted EITF 07-05. EITF 07-05 clarifies the determination of whether an instrument (or an embedded feature) is indexed to an entitys own stock, which would qualify as a
scope exception under SFAS 133. See Note 1 for the impact of adoption of EITF 07-05 on the Companys financial statements.

Fair Value
Accounting

In April 2009, the FASB issued Staff Position No. FAS 107-1 and APB 28-1, Interim Disclosures about Fair Value
of Financial Instruments (FSP FAS 107-1 and APB 28-1). FSP FAS 107-1 and APB 28-1 extends the disclosure requirements of SFAS 107 to interim period financial statements, in addition to the existing requirements for annual
periods and reiterates SFAS 107s requirement to disclose the methods and significant assumptions used to estimate fair value. FSP FAS 107-1 and APB 28-1 is effective for the Companys interim and annual periods commencing with its
June 30, 2009 consolidated financial statements and will be applied on a prospective basis. FSP FAS 107-1 and APB 28-1 did not have a material impact on the Companys consolidated financial statements.

In April 2009, the FASB issued FSP 157-4, Determining Fair Value When the Volume and Level of Activity for the Asset or Liability Have
Significantly Decreased and Identifying Transactions That Are Not Orderly(FSP 157-4). FSP 157-4 provides additional guidance for estimating fair value in accordance with SFAS 157 when the volume and level of activity
for the asset or liability have significantly decreased and identifying circumstances that indicate a transaction is not orderly. The adoption of FSP 157-4 did not have a significant impact on the Companys financial statements or the fair
values of our assets or liabilities.

In April 2009, the FASB issued FSP 115-2 and SFAS 124-2, Recognition and Presentation
of Other-Than-Temporary Impairments(FSP 115-2 and SFAS 124-2). FSP 115-2 and SFAS 124-2 amend the other-than-temporary impairment guidance in U.S. generally accepted accounting principles (U.S. GAAP) for debt
securities to make the guidance more operational and to improve the presentation and disclosure of other-than-temporary impairments on debt and equity securities in the financial statements. However, they do not amend existing recognition and
measurement guidance related to other-than-temporary impairments of equity securities. The adoption of FSP 115-2 and SFAS 124-2 did not have a significant impact on the Companys financial statements or the fair values of the
Companys assets or liabilities.

Subsequent Events

In June 2009, FASB issued SFAS No. 165, Subsequent Events (SFAS 165) which establishes general standards of accounting for and disclosures of events that occur after the balance
sheet date but before the financial statements are issued or available to be issued. It is effective for interim and annual periods ending after June 15, 2009. In accordance with SFAS 165, the Company evaluated subsequent events after the
balance sheet date of June 30, 3009 through August 10, 2009. The Company applied the provisions of SFAS 165 to determine the accounting and disclosure required for the subsequent event detailed in Note 12 below.

Codification

In June 2009, the FASB issued
SFAS No. 168, The FASB Accounting Standards Codification and the Hierarchy of Generally Accepted Accounting Principles (GAAP) - a replacement of FASB Statement No. 162, which will become the source of
authoritative U.S. GAAP recognized by the FASB to be applied to nongovernmental entities. It is effective for financial statements issued for interim and annual periods ending after September 15, 2009. The Company does not believe that the
adoption of SFAS 168 will have a material impact on the Companys consolidated financial statements.

Joint Venture Accounting

In June 2009, the FASB issued SFAS 167, Amendments to FASB Interpretation No. 46(R)(SFAS 167), which
changes the approach to determine the primary beneficiary of a variable interest entity (VIE) and requires companies to more frequently assess whether they must consolidate VIEs. This new standard is effective for the Company beginning
on January 1, 2010. The Company is currently assessing the potential impact of SFAS 167 on its consolidated financial statements.

12. Subsequent Event

On July 1, 2009, the Company entered into amendment agreements with certain holders of its 2008 Notes to modify certain terms of the 2008 Notes. The amendments became effective on July 6, 2009. Pursuant to
their original terms, the 2008 Notes may be amended and restated with the written consent of the holders representing at least 66.67% of the 2008 Notes outstanding (the Required Holders). As of July 1, 2009, there was approximately
$29.5 million aggregate principal amount of the 2008 Notes outstanding. The Company entered into the amendment agreements with all but one of the noteholders for approximately $25.6 million, or 86.8%, of the 2008 Notes.

The amendment agreements provide for the following:



| |  |  | lowering the conversion price from $2.13 to $1.74;
| | - |  | --------------------------------------------------



| |  |  | lowering the price at which the 2008 Notes are subject to automatic conversion at the Companys option and subject to the satisfaction of certain conditions
from $8.18 to $3.48;
| | - |  | ---------------------------------------------------------------------------------------------------------------------------------------------------------------------------------



| |  |  | clarifications for the provisions that provide for interest and make-whole payments to be made in shares of the Companys common stock, subject to certain
restrictions;
| | - |  | ------------------------------------------------------------------------------------------------------------------------------------------------------------------------



| |  |  | modification of the anti-dilution protections from full ratchet to, in most cases, a version of broad-based weighted average, subject to certain limitations; and
| | - |  | -----------------------------------------------------------------------------------------------------------------------------------------------------------------



| |  |  | modification of certain covenants intended to provide the Company with greater flexibility to engage in certain financing and other strategic transactions,
including the ability to incur indebtedness or liens, engage in restructuring transactions involving its 2007 Notes and engage in certain asset sales; and
| | - |  | ----------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------



| |  |  | a relinquishment by the holders of the 2008 Notes who signed amendment agreements of certain rights and potential rights related to conversions of 2008 Notes and
payments made by the Company with respect thereto prior to July 1, 2009.
| | - |  | ------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------

As disclosed in Note 10, one holder
of 2008 Notes that currently holds approximately $3.2 million in aggregate principal amount is a party to a pending lawsuit against the Company, whereby that holder also seeks declaratory judgment that its 2008 Notes may not be amended by the
Required Holders without that holders consent. This holder has not signed the amendments as of August 10, 2009. In connection with the amendment, the Company paid $1.5 million in advisory fees.

The Company is currently assessing the potential impact of the debt amendments on its future consolidated financial statements.

and uncertainties set forth below and in the section of this report entitled Risk Factors.

Overview

We operate in two business segments, biofuels and specialty enzymes. Our biofuels business segment operates through our wholly-owned subsidiary, Verenium
Biofuels Corporation and jointly-owned subsidiaries with BP, Galaxy and Vercipia, and is focused on developing unique technical and operational capabilities designed to enable the production and commercialization of biofuels, in particular ethanol
produced from cellulosic biomass. We believe the most significant commercial opportunity for our biofuels business segment will be derived from the large-scale commercial production of cellulosic ethanol derived from multiple biomass feedstocks,
with our initial focus on energy canes and grasses. Our specialty enzymes segment develops high-performance enzymes for use within the alternative fuels, specialty industrial processes, and animal nutrition and health markets to enable higher
throughput, lower costs, and improved environmental outcomes. We believe the most significant commercial opportunity for our specialty enzymes business segment will be derived from continued sales, and gross product margins from our existing
portfolio of enzyme products.

Our biofuels and specialty enzymes businesses are both supported by a research and development team with
expertise in gene discovery and optimization, cell engineering, bioprocess development, biochemistry and microbiology. Over the past 16 years, our research and development team has developed a proprietary technology platform that has enabled us to
apply advancements in science to discovering and developing unique solutions in complex industrial or commercial applications. We have dedicated substantial resources to the development of our proprietary technologies, which include capabilities for
sample collection from the worlds microbial populations, generation of DNA libraries, screening of these libraries using ultra high-throughput methods capable of analyzing more than one billion genes per day, and optimization based on our gene
evolution technologies. We have continued to shift more of our resources from technology development to commercialization efforts for our existing and future technologies and products. While our technologies have the potential to serve many large
markets, our primary areas of focus for product development are (i) integrated solutions for the production of advanced biofuels, such as cellulosic ethanol, and (ii) specialty enzymes for alternative fuels, specialty industrial processes,
and animal nutrition and health. We have current collaborations and agreements with market leaders, such as BP, Bunge Oils, and Cargill Health and Food Technologies, each of which complement our internal technology and product development efforts.

We expect to continue to invest in these commercialization efforts, primarily in the area of biofuels. We believe this will not only
benefit our mission to advance the commercialization of cellulosic ethanol within our biofuels business unit, but will also enable us to create additional enzyme market opportunities that are focused on external applications for the broader biofuels
industry.

We have a substantial intellectual property estate comprising more than 250 issued patents and more than 350 pending patents as
of June 30, 2009. We believe that we can leverage our intellectual property estate to enhance and improve our technology development and commercialization efforts across both business units while maintaining protection on key intellectual
property assets.

For the six months ended June 30, 2009, total revenues decreased $2.9 million, or 9%, compared to the six months
ended June 30, 2008. The decrease in revenue was primarily attributed to a $3.6 million decrease in product revenue related to the cancellation of our Bayovac-SRS and Quantum product lines during 2008 and lower sales of Phyzyme to Danisco,
partially offset by an increase in sales of our Fuelzyme-LF enzyme compared to the same period in 2008. Collaborative and grant revenue for the six months ended June 30, 2009 increased $0.7 million, or 7%, compared to the same periods in 2008
primarily due to Department of Energy grant revenue partially offset by the completion of our Sygnenta collaboration as of December 31, 2008. We expect that our product revenue will continue to represent the majority of our total revenue in the
future.

Our strategic partners often pay us before we earn the revenue, and revenue recognition from these payments is deferred until
earned. As of June 30, 2009, we had $3.6 million in deferred revenue, of which $3.1 million was related to funding from collaborative partners and $0.5 million was related to product sales.

Excluding our non-cash gains in the first quarter of 2009 attributed to our 2008 Notes, we have incurred
net losses since our inception. As of June 30, 2009, we had a working capital deficit of $16.8 million, and an accumulated deficit of $630.2 million. Our results of operations have fluctuated from period to period and likely will continue to
fluctuate substantially in the future. We expect to incur losses into the foreseeable future as a result of any combination of one or more of the following:



| |  |  | anticipated additional investments to implement our biofuels commercialization strategy, including capital expenditures related to optimization of our demonstration
facility, and capital or operating costs we may incur for land acquisition, feedstock development, and design and engineering for our first commercial plants through our joint ventures with BP;
| | - |  | ----------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------



| |  |  | maintaining our sales and marketing infrastructure to support our specialty enzyme business;
| | - |  | --------------------------------------------------------------------------------------------



| |  |  | our continued investment in manufacturing facilities necessary to meet anticipated demand for our products; and
| | - |  | ---------------------------------------------------------------------------------------------------------------



| |  |  | continued research and development expenses for our internal product candidates.
| | - |  | --------------------------------------------------------------------------------

Results of operations for any period may be unrelated to results of operations for any other period. In addition, we believe that our historical results
are not a good indicator of our future operating results.

As more fully described in the Risk Factorsbeginning on page 47,
Liquidity and Capital Resourcesbeginning on page 38 and Note 1 of the Notes to Condensed Consolidated Financial Statements beginning on page 6 of this report, our independent registered public accounting firm has included an
explanatory paragraph in its report on our 2008 financial statements related to the substantial doubt in our ability to continue as a going concern. While we believe that we will be successful in raising or generating additional cash through a
combination of corporate partnerships and collaborations, federal, state and local grant funding, selling or financing assets, incremental product sales and the sale of equity or debt securities, if we are unsuccessful in raising additional capital
from any of these sources, we may need to defer, reduce or eliminate certain planned expenditures, restructure or significantly curtail our operations, file for bankruptcy or cease operations.

Recent Strategic Events

2008 Notes Amendment

On July 1, 2009, we entered into amendment agreements with certain holders of our 2008 Notes to modify certain terms of the 2008
Notes. The amendments became effective on July 6, 2009. Pursuant to the terms of the 2008 Notes, the 2008 Notes may be amended and restated with the written consent of the holders representing at least 66.67% of the 2008 Notes outstanding (the
Required Holders). As of July 1, 2009, there was approximately $29.5 million aggregate principal amount of the 2008 Notes outstanding. We entered into the amendment agreements with all but one of the noteholders for approximately
$25.6 million or 86.8% of the 2008 Notes.

The amendment agreements provide for the following:



| |  |  | lowering the conversion price from $2.13 to $1.74;
| | - |  | --------------------------------------------------



| |  |  | lowering the price at which the 2008 Notes are subject to automatic conversion at the Companys option and subject to the satisfaction of certain conditions
from $8.18 to $3.48;
| | - |  | ---------------------------------------------------------------------------------------------------------------------------------------------------------------------------------



| |  |  | clarifications for the provisions that provide for interest and make-whole payments to be made in shares of our common stock, subject to certain restrictions;
| | - |  | --------------------------------------------------------------------------------------------------------------------------------------------------------------



| |  |  | modification of the anti-dilution protections from full ratchet to, in most cases, a version of broad-based weighted average, subject to certain limitations; and
| | - |  | -----------------------------------------------------------------------------------------------------------------------------------------------------------------



| |  |  | modification of certain covenants intended to provide us with greater flexibility to engage in certain financing and other strategic transactions, including the
ability to incur indebtedness or liens, engage in restructuring transactions involving our 2007 Notes and engage in certain asset sales; and
| | - |  | -------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------



| |  |  | a relinquishment by the holders of the 2008 Notes who signed amendment agreements of certain rights and potential rights related to conversions of 2008 Notes and
payments made by us with respect thereto prior to July 1, 2009.
| | - |  | ---------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------

As disclosed in Note 10 above, one holder of
2008 Notes that currently holds approximately $3.2 million in aggregate principal amount is a party to a pending lawsuit against us, whereby that holder also seeks declaratory judgment that its 2008 Notes may not be amended by the Required Holders
without that holders consent. In connection with the amendment, we paid $1.5 million in advisory fees.

Results of Operations

Selected Segment Financial Data

Our business consists of two business units, which we refer to as
our biofuels segment and our specialty enzymes segment. The biofuels segment is focused on developing unique technical and operational capabilities designed to enable the production and commercialization of biofuels, in particular ethanol from
cellulosic biomass. The specialty enzymes segment develops high performance enzymes for use within the alternative fuels, specialty industrial processes, and animal nutrition and health markets to enable higher throughput, lower costs, and improved
environmental outcomes.

We assess performance and allocate resources based on discrete financial information for the biofuels and
specialty enzymes segments. For the biofuels segment, performance is assessed based on total operating expenses and capital expenditures. For the specialty enzymes segment performance is assessed based on total revenues, product revenues, product
gross profit, total operating expenses and capital expenditures. For the three and six months ended June 30, 2009, the specialty enzyme segment comprised 100% of our product revenue and cost of product revenue. Our operating expenses for each
segment include direct and allocated research and development and selling, general and administrative expenses. In managements evaluation of performance, certain corporate operating expenses are excluded from the business segments such as:
non-cash share-based compensation, restructuring charges, severance, depreciation and amortization, and other corporate expenses, which are not allocated to either business segment. In addition, we evaluate segment performance based upon capital
expenditures and other assets that are specifically identified to the business segment, excluding certain corporate assets such as cash, short-term investments, and other assets that can be attributed to, or utilized by, both business segments.
Expenses and assets shared by the segments require the use of judgments and estimates in determining the allocation of expenses to the two segments. Different assumptions or allocation methods could result in materially different results by segment.
Further, expenses allocated to each of the two segments may not be indicative of the expenses of each operating segment if such segments operated on a stand-alone basis.

Selected operating results for the three and six months ended June 30, 2009 and 2008, and identifiable assets as of June 30, 2009 and December 31, 2008 for each of our business segments is set forth
below (in thousands):

Revenues decreased 11%, or $2.0 million, to $16.3 million for the three months ended June 30, 2009
and 9%, or $2.9 million, to $30.7 million for the six months ended June 30, 2009. For the three and six months ended June 30, 2009, our revenue mix continued to shift to a larger percentage of product and grant revenues, consistent with
our strategy to grow product sales and biofuels projects, and de-emphasize collaborations that are not core to our strategic market focus. Product and grant revenues represented 92% of total revenues for the three and six months ended June 30,
2009, as compared to 78% for the three and six months ended June 30, 2008.

Product revenues decreased $2.9 million, or 22%, for the
three months ended June 30, 2009 and $3.5 million, or 14%, for the six months ended June 30, 2009 as compared to the same periods in 2008. This decrease is attributed primarily to the following factors:



| |  |  | While gross shipments of Phyzyme for the three and six months ended June 30, 2009 remained at levels comparable to 2008, our reported net Phyzyme revenue was
lower than our reported net revenue in the same periods of the prior year. This is attributed to a larger percentage of Phyzyme sales manufactured by Genencor, a subsidiary of Danisco, for which we recognize only the profit share component of
Phyzyme sales. Due to capacity constraints during late 2008, we contracted with Genencor to serve as a second-source manufacturer of Phyzyme. Pursuant to current accounting rules, we recognize revenue from Phyzyme that is manufactured by Genencor in
an amount equal to the net profit share received from Danisco, as compared to the full value of the manufacturing costs plus profit share we currently recognize for Phyzyme we manufacture at Fermic.

| |  |  | We discontinued two of our product lines, Bayovac-SRS and Quantum, during early 2008.
| | - |  | -------------------------------------------------------------------------------------

Revenues from Phyzyme represented approximately 79% and 76% of total product revenues for the three and six months ended June 30, 2009 as compared
to 79% and 73% for the three and six months ended June 30, 2008. We expect that Phyzyme will continue to represent a significant percentage of our total product revenues in the foreseeable future.

Given the worldwide recession, we cannot be certain that demand for our enzyme products and resulting sales will meet expectations.

In particular:



| |  |  | Following a year of substantial growth in revenues and related market share of our Phyzyme enzyme, we and our partner, Danisco, have seen a softening in the phytase
animal feed market attributed to a recessionary decline in consumer consumption of protein and financial distress in the poultry industry, which have negatively impact demand for feed and thus our enzyme.
| | - |  | ---------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------



| |  |  | Demand for Fuelzyme has continued to be impacted by challenges in the corn ethanol industry, which has seen significant distress over the last year due to high corn
prices and low ethanol prices. There have been several well-publicized bankruptcies, including two of the largest producers of corn ethanol in the U.S. operating rates in the industry are significantly reduced, which negatively impacts demand for
enzymes.
| | - |  | ------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------



| |  |  | One of our prime initial targets for Purifine is the soybean oil processing market in Latin America, which has suffered drought, political upheaval over taxes on
soybeans, and overall challenging market conditions since early 2008. As a result, adoption of Purifine in the region has been delayed, thus Purifine revenue is below expectations. Though we anticipate a ramp-up in Purifine revenues, it will be
slower than initially expected.
| | - |  | ------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------

We experienced a decline in our product revenue during the three and six months ended
June 30, 2009 due in part to all of these factors.

Grant revenue increased 353%, or $3.5 million, to $4.5 million for the three
months ended June 30, 2009 and 355%, or $5.5 million, to $7.0 million for the six months ended June 30, 2009. The increase in grant revenues was primarily attributable to various new grants awarded during late 2008 and early 2009 from the
Department of Energy to further optimize our demonstration-scale facility. We continue to pursue additional opportunities to secure federal, state or local agency funding to support our biofuels initiatives. As of June 30, 2009, we have
committed funding from various governmental agencies totaling $19.6 million through 2012, and expect to continue to see an increase in grant revenue during 2009 as compared to 2008.

Collaborative revenue decreased 67%, or $2.6 million, to $1.3 million for the three months ended June 30, 2009 and 65%, or $4.8 million, to $2.6
million for the six months ended June 30, 2009. We have continued to de-emphasize collaborations that are not core to our current focus in favor of greater emphasis on sales of products and biofuels projects. We anticipate that collaborative
revenue will continue to decrease in 2009 as compared to 2008, due in large part to this de-emphasis of non-strategic collaborations and decrease in revenue related to the expected wind-down of projects with existing strategic collaborators such as
Syngenta, and BASF. For example, under the terms of our 10-year agreement with Syngenta, our two-year funding period totaling $8 million per year expired on December 31, 2008. We do not anticipate that we will continue to receive significant
funding from Syngenta under this agreement.

We will continue to pursue opportunities to expand, renew, or enter into new collaborations
that we believe fit our strategic focus and represent product commercialization opportunities in the future; however, there can be no assurance that we will be successful in renewing or expanding existing collaborations, or securing new
collaboration partners.

Our revenues have historically fluctuated from period to period and likely will continue to fluctuate
substantially in the future based upon the adoption rates of our new and existing commercial products, timing and composition of funding under existing and future collaboration agreements, timing and amount of funding under government grants, as
well as regulatory approval timelines for new products. We anticipate that our revenue mix will continue to shift toward a higher percentage of product and grant revenue.

Product Gross Margin

|Product gross margin    |  |                             | 3,049  |      |   | 3,799    |                           | (20 | )%   |  |      | 7,863  |          |   | 7,123  |  | 10  | % 

Cost of product revenue includes both fixed and variable costs, including materials and supplies,
labor, facilities, royalties and other overhead costs, associated with our product revenues. Excluded from cost of product revenue are costs associated with the scale-up of manufacturing processes for new products that have not reached
commercial-scale production volumes, which we include in our research and development expenses. Cost of product revenue decreased $2.1 million, or 22%, to $7.5 million for the three months ended June 30, 2009 and decreased $4.2 million, or 24%,
to $13.2 million for the six months ended June 30, 2009. This decrease resulted primarily from the change in accounting for our Phyzyme product revenue and related cost manufactured by Genencor as described below and lower capacity utilization
at Fermic as a result of the decrease in product revenue described above.

We manufacture most of our enzyme products through a
manufacturing facility in Mexico City, owned by Fermic S.A., or Fermic. We also have contracted with Genencor, a subsidiary of Danisco, to serve as a second-source manufacturer of Phyzyme. As discussed above, we recognize revenue from Phyzyme that
is manufactured by Genencor in an amount equal to the net profit share received from Danisco, as compared to the full value of the manufacturing costs plus profit share we currently recognize for Phyzyme we manufacture at Fermic. While this revenue
recognition treatment has little or no negative impact on the gross margin in absolute dollars we recognize for every sale of Phyzyme, it does have a negative impact on the gross product revenue we recognize for Phyzyme as the volume of Phyzyme
manufactured by Genencor increases.

Product gross margin totaled $3.0 million, or 29% of product revenue for the three months ended
June 30, 2009 compared to $3.8 million, or 28% of product revenue for the three months ended June 30, 2008, and $7.9 million, or 37% of product revenue, for the six months ended June 30, 2009 compared to $7.1 million, or $29% of
product revenue for the comparable period in 2008. Gross margin percentage improvement for the six months ended June 20, 2009 reflects various factors, specifically:



| |  |  | Due to our manufacturing arrangement with Genencor to serve as a second-source manufacturer for Phyzyme as previously described, we record revenue and costs related
to Phyzyme that Genencor manufactures on a net basis versus a gross basis. This had no impact on the absolute value of our gross margin, but resulted in an increase of seven percentage points to the gross margin percentage reported for the six
months ended June 30, 2009.
| | - |  | ----------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------



| |  |  | During the six months ended June 30, 2008, gross margin percentage was lower due to (i) inventory losses related to contamination issues in our Phyzyme
enzyme manufacturing process; and (ii) incremental zero-margin freight revenue and related costs incurred to meet customer ship dates. Both of these factors negatively impacted gross profit and resulted in a lower gross margin in 2008.
| | - |  | ---------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------

For the reasons described above, we believe that product gross margin (dollars) is a better indication of performance
than product gross margin percentage.

In addition because a large percentage of our manufacturing costs are fixed, during the three months
ended June 30, 2009 we realized a decline in gross margin related to lower capacity utilization as product revenues decreased. Our gross margin may be negatively impacted in the future if our product revenues decrease or if they do not grow in
line with our increase in minimum capacity requirements at Fermic. Our gross margins are also dependent upon the mix of product-related sales as the cost of product-related revenue varies from product to product.

Because Phyzyme represents a significant percentage of our product revenue, our product gross margin is impacted to a great degree by the gross margin
achieved on sales of Phyzyme. Under our manufacturing and sales agreement with Danisco, we sell our Phyzyme inventory to Danisco at our cost and then, under a license agreement, share 50% of Daniscos profit, as defined, when the product is
sold to the end user. As a result, our total cost of product revenue for Phyzyme is incurred as we ship product to Danisco, and profit share revenue is recognized in the period in which the product is sold to the end user as reported to us by
Danisco. We may record our quarterly profit share revenue based on



33

##### Table of Contents

estimates from Danisco, and the final calculation of profit share is sometimes finalized in the subsequent quarter; accordingly, we are subject to potential
adjustments to our actual profit share revenue from quarter-to-quarter. These adjustments, while typically considered immaterial in absolute dollars, could have a significant impact on our reported product gross margin from quarter-to-quarter.

In addition, our supply agreement with Danisco for Phyzyme contains provisions which allow Danisco, with six months advance notice, to
assume manufacturing rights for Phyzyme. If Danisco decides to exercise this right, we will likely experience excess capacity at Fermic. If we are unable to absorb this excess capacity with other products in the event that Danisco assumes all or a
portion of Phyzyme manufacturing rights, this may have a negative impact on our revenues and our product gross margin.

Operating
Expenses

Research and development and selling, general and administrative expenses for the periods ended June 30, 2009 and 2008
are as follows (in thousands):

Our operating expenses excluding cost of product revenue for the three and six months ended
June 30, 2009 increased 13% and 11% compared to the prior comparable periods in 2008, related primarily to the acceleration of biofuels development and commercialization efforts in 2009.

Research and Development

Research
and development expenses consist primarily of costs associated with development of our technologies and our product candidates, including costs associated with out pilot and demonstrationscale cellulosic ethanol facilities, manufacturing
scale-up and bioprocess development for our current products, and costs associated with research activities performed on behalf of our collaborators.

For the three and six months ended June 30, 2009, we estimate that approximately 32% and 29% of our research and development personnel costs, based upon hours incurred, were spent on unfunded product and
technology development, and that approximately 68% and 71% were spent on research activities funded in whole or in part by our Galaxy joint venture. For the three and six months ended June 30, 2008, we estimate that approximately 71% of our
research and development personnel costs, based upon hours incurred, were spent on unfunded product and technology development, and that approximately 29% were spent on research activities funded by our collaborations and grants. The increase in
percentage of time spent on funded product and technology development from the prior year is primarily attributed to our focus on cellulosic ethanol process development, which is partially funded by BP through our Galaxy joint venture.

We have a limited history of developing commercial products and technologies. We determine which products and technologies to pursue independently
based on various criteria, including: investment required, estimated time to market, regulatory hurdles, infrastructure requirements, and industry-specific expertise necessary for successful commercialization. Successful products and technologies
require significant development and investment prior to regulatory approval and commercialization. As a result of the significant risks and uncertainties involved in developing and commercializing such products, we are unable to estimate the nature,
timing, and cost of the efforts necessary to complete each of our major projects. These risks and uncertainties include, but are not limited to, the following:



| |  |  | Our products and technologies may require more resources than we anticipate if we are technically unsuccessful in initial development or commercialization efforts;
| | - |  | -------------------------------------------------------------------------------------------------------------------------------------------------------------------



| |  |  | The outcome of research is unknown until each stage of testing is completed, up through and including trials and regulatory approvals, if needed;
| | - |  | -------------------------------------------------------------------------------------------------------------------------------------------------



| |  |  | It can take many years from the initial decision to perform research through development until products and technologies, if any, are ultimately marketed; and
| | - |  | --------------------------------------------------------------------------------------------------------------------------------------------------------------



| |  |  | We have product candidates and technologies in various stages of development related to collaborations and grants as well as internally developed products and
technologies. At any time, we may modify our strategy and pursue additional collaborations for the development and commercialization of some products and technologies that we had intended to pursue independently. For example, in 2008 we entered into
a joint collaboration with BP to co-fund the advancement and validation of our cellulosic ethanol process technology, which had previously been largely self-funded.

Any one of these risks and uncertainties could have a significant impact on the nature, timing, and costs
to complete our product and technology development efforts. Accordingly, we are unable to predict which potential commercialization candidates we may proceed with, the time and costs to complete development, and ultimately whether we will have any
products or technologies approved by the appropriate regulatory bodies. The various risks associated with our research and development activities are discussed more fully in this report under Risk Factors.

Our research and development expenses increased $1.2 million to $16.1 million (including share-based compensation of $0.3 million) for the three months
ended June 30, 2009, and increased $4.2 million to $33.9 million (including share-based compensation of $1.8 million) for the six months ended June 30, 2009 compared to $14.9 million and $29.8 million (including share-based compensation of
$1.1million and $2.5 million) for the comparable periods in 2008. Our research and development expenses by operating segment for the three and six months ended June 30, 2009 and 2008 were as follows (in thousands):

Biofuels Research and Development

Research and development expenses related to our biofuels business include costs related to our ongoing development and validation of our cellulosic
ethanol process technology, including, but not limited to, enzyme discovery and development and bioprocess development designed to improve ethanol yields and reduce cost-per-gallon, feedstock testing and validation at the laboratory, pilot- and
demonstration-plant scale, as well as costs related to commissioning, optimization and operation of our demonstration-scale facility in Jennings, Louisiana. During 2008, costs related to our ligno-cellulosic programs which were partially funded by
Syngenta, were included in Specialty Enzymes research and development. In 2009, we have categorized these costs in our Biofuels segment.

Our biofuels research and development expenses increased $6.0 million and $14.2 million for the three and six months ended June 30, 2009 from $8.4 million and $15.3 million for the comparable periods in 2008. This increase is related
to acceleration of our biofuels technology development efforts during 2008, which has continued in 2009, particularly related to our demonstration-scale facility commissioning and optimization at our site in Jennings, Louisiana, which BP has
substantially funded through our Galaxy joint venture. As described in more detail below, our gross research and development costs related to Galaxy and Vercipia are included in Research and development on our Condensed Consolidated
Statements of Operations, with BPs cost reimbursement to us included in Loss attributed to noncontrolling interests in consolidated entities.

We consider our current cellulosic ethanol technology under development to be our Generation 1 or Gen 1 technology. To date, we have demonstrated that our Gen 1 technology can produce
cellulosic ethanol at a small scale in the laboratory, pilot plant, and demonstration-scale facility, but at yields and cost that are not yet commercially viable. We will require continued and substantial investment to further develop our Gen 1
technology, and continue to believe that Gen 1 will produce a viable technology that could be deployed on a commercial scale as early as 2012. Our first commercial plant is scheduled to break ground in 2010.

Specialty Enzymes Research and Development

Research
and development expenses related to our specialty enzyme business include costs related to ongoing bioprocess development and manufacturing process yield improvements, funded support for research collaborations and to a lesser extent, early stage
product development.

Due to limited capital resources and challenging economic conditions, we are not spending significant resources on
early stage specialty enzyme product development during 2009 without additional investment from strategic partners.

Our specialty enzymes
research and development expenses decreased $4.8 million and $10.0 million for the three and six months ended June 30, 2009. This decrease is related primarily to our shift in focus to biofuels process development, and to a lesser extent the
de-emphasis of early stage product development for our specialty enzyme business segment and collaboration and grant work not core to our current focus.

Selling, general and administrative expenses increased $1.8 million, or 20%, to $10.9 million
(including share-based compensation of $2.3 million) for the three months ended June 30, 2009 and increased $1.3 million, or 7%, to $20.0 million (including share-based compensation of $3.3 million) for the six months ended June 30, 2009.
Excluding the impact of share-based compensation, selling, general and administrative expenses increased $1.1 million and $1.7 million for the three and six months ended June 30, 2009 as compared to the same period in 2008, primarily due to the
biofuels development efforts for our first commercial plant, which BP partially funds through our Vercipia joint venture.

Share-Based
Compensation Charges

We recognized $2.6 million, or $0.03 per share, and $2.7 million, or $0.04 per share, in share-based compensation
expense for our share-based awards during the three months ended June 30, 2009 and 2008 and $5.1 million, or $0.06 per share, and $6.2 million, or $0.10 per share, during the six months ended June 30, 2009 and 2008. These charges had no
impact on our reported cash flows. Share-based compensation expense was allocated among the following expense categories (in thousands):

During the second quarter of 2009, the Board of Directors approved to accelerate the vesting of a
group of performance-based options held by certain of our executives. The acceleration reduced the vesting term from seven to four years for approximately 70% of the total grants, as well as fully accelerated two additional executive grants,
resulting in additional stock compensation expense of approximately $1.6 million.

Our net share-based compensation charges decreased
primarily because of the suspension of our employee stock purchase plan during the first quarter of 2009 and an overall decrease in equity awards granted since our merger with Celunol Corp in 2007.

Interest and expense, net

Interest
income on cash and short term investments decreased to less than $0.1 million for the three and six months ended June 30, 2009 compared to $0.2 million and $0.7 million for the three and six months ended June 30, 2008. The decrease was
attributed to lower average cash and investment balances.

Interest expense was $3.3 million for the three months ended June 30, 2009
compared to $2.6 million for the three months ended June 30, 2008, net of $1.7 million in capitalized interest for the demonstration facility. Our demonstration-scale facility was placed in service in February 2009, and as such, we ceased
capitalizing interest on that date. Interest expense was $6.5 million, net of $1.0 million in capitalized interest for the demonstration facility, for the six months ended June 30, 2009 compared to $4.8 million for the six months ended
June 30, 2008, net of $2.5 million in capitalized interest for the demonstration facility. The increase in interest expense from the comparable periods in 2008 was primarily attributed to the decrease in capitalized interest partially offset by
the decrease in 2008 Notes principal outstanding from conversions. We recorded aggregate interest expense related to the 2008 Notes of $1.6 million for the three months ended June 30, 2009 and $4.1 million for the six months ended June 30,
2009 compared to $2.7 million and $3.7 million for the three and six months ended June 30, 2008, comprised of the following (in thousands):

Loss on Exchange of Convertible Notes

In connection with the issuance of the 2008 Notes, we exchanged $18.5 million in aggregate principal amount of the 2007 Notes for approximately $16.7
million in aggregate principal amount of the 2008 Notes. Pursuant to current accounting rules, we recorded a non-cash loss on the exchange of $3.6 million, equal to the difference between the carrying value of the 2007 Notes and the fair value of
the 2008 Notes and warrants issued.

Gain (Loss) on Net Change in Fair Value of Derivative Assets and Liabilities

The fair value of the compound embedded derivative, warrants, and the convertible hedge transaction in connection with our 2008 Notes are recorded as a
derivative asset or liability and marked-to-market each balance sheet date. The change in fair value is recorded in the Condensed Consolidated Statement of Operations as Gain (loss) on net change in fair value of derivative assets and
liabilities. We recorded a net loss of $9.9 million and a net gain of $3.4 million for the three and six months ended June 30, 2009 compared to a net gain of $2.3 million and $1.7 million for the three and six months ended June 30,
2008 related to the change in fair value of our recorded derivative asset and liabilities.

Gain (loss) on Debt Extinguishment

During the three and six months ended June 30, 2009, pursuant to current accounting rules, we recorded a gain on debt
extinguishment of $2.5 million and $6.1 million, calculated as the difference between the carrying value of the converted 2008 Notes and the fair value of the shares of common stock delivered to the noteholders upon conversion. The carrying value of
the converted 2008 Notes for the three and six months ended June 30, 2009 was equal to the $19.3 million and $29.4 million of principal less the unamortized debt discount and issuance costs, which totaled $14.4 million and $21.8 million, as of
the conversion date. During the three and six months ended June 30, 2009, we issued a total of 21.8 million and 30 million shares with a total market value as of the dates of conversion of $11.9 million and $15.7 million to settle the
2008 Notes and make-whole payments.

Loss Attributed to Noncontrolling Interests in Consolidated Entities

In connection with the initial phase of our strategic partnership with BP, we formed Galaxy as a special purpose entity. We are considered the primary
beneficiary of Galaxy and consolidate its financial results. Pursuant to current accounting rules, the transaction fees and joint development fees are accounted for as follows:



| |  |  | The license to technology we granted to Galaxy and ongoing joint development work we perform for Galaxy are accounted for as capital contributions to Galaxy;
| | - |  | -------------------------------------------------------------------------------------------------------------------------------------------------------------



| |  |  | Transaction fees and joint development fees paid by BP are accounted for as capital contributions to Galaxy, which are subsequently distributed to us as a reduction
to our capital account;
| | - |  | --------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------



| |  |  | Ongoing joint development fees are accounted for as a monthly expense of Galaxy.
| | - |  | --------------------------------------------------------------------------------

In connection with the second phase of our strategic partnership with BP, we hold a 50% interest in Vercipia, a special purpose entity. We are considered
the primary beneficiary of Vercipia and consolidate its financial results. Pursuant to current accounting rules, the ongoing joint development is considered a monthly expense of Vercipia. All contributions are contributed directly into Vercipia.

##### Table of Contents

As a result, our consolidated financial statements include a line item called Noncontrolling
interests in consolidated entities. On our Condensed Consolidated Balance Sheets, this line reflects BPs ownership of Galaxys and Vercipias equity. This line item is reduced by BPs 50% share of Galaxys and
Vercipias losses, and increased by cash contributions made by BP. BPs share of losses is reflected in our Condensed Consolidated Statements of Operations as Loss attributed to noncontrolling interests in consolidated
entities. Galaxy and Vercipia have incurred losses through June 30, 2009, 50% of which have been allocated to BP, and we anticipate these entities will continue to incur losses related to ongoing joint development through at least the
initial joint development program and construction processes.

Liquidity and Capital Resources

Since inception, we have financed our business primarily through the sale of common and preferred stock, funding from strategic partners and government
grants, the issuance of convertible debt, and product sales. As of June 30, 2009 our strategic partners, most recently including BP, have provided us with more than $350 million in funding since inception, including $19.6 million from various
government agencies, and are committed to additional funding of more than $30 million through 2012, subject to our performance under existing agreements, excluding milestone payments, license and commercialization fees, and royalties or profit
sharing. Our committed funding includes $15.5 million from our Vercipia joint venture with BP, announced in February 2009, $5.0 million of which was paid on July 1, 2009. Vercipia will act as a separate commercial entity, with the $15.5 million
BP funding used solely for this entity.

Our future committed funding is subject to our performance under existing agreements, and is
concentrated within a limited number of collaborators. Our failure to successfully maintain our relationships with these collaborators could have a material adverse impact on our operating results and financial condition.

Capital Requirements

As of
June 30, 2009, we had available cash and cash equivalents of approximately $14.8 million, including approximately $4.9 million which relates to Vercipia and is to be used solely for its operations. Historically, we have funded our capital
requirements through available cash, issuances of debt and equity, product, collaboration and grant revenue, capital leases and equipment financing line of credit agreements. Since March 2007, we have raised approximately $158.8 million in net cash
proceeds from convertible debt issuances to fund our cellulosic ethanol pilot and demonstration-scale facilities and other working capital requirements. As of June 30, 2009, we had a working capital deficit of $16.8 million.

We will require additional capital to fund our operations. Our independent registered public accounting firm has included an explanatory paragraph in its
report on our 2008 financial statements related to the substantial doubt in our ability to continue as a going concern. Our cash at June 30, 2009, along with anticipated cash from grants, revenue, our commitment from BP and other sources may
not be sufficient to meet cash requirements to fund our operating expenses, capital expenditures, required and potential payments under our 2007 Notes and our 2008 Notes, and working capital requirements beyond 2009 without additional sources of
cash and/or the deferral, reduction or elimination of significant planned expenditures.

We will also need to raise sufficient capital to
fund the construction of our first commercial cellulosic ethanol plant to be located in Highlands County, Florida. We recently entered into a joint venture with BP intended to advance the design and engineering of the commercial facility, and we
expect to break ground on this facility in 2010. We estimate that the total costs of construction for this first commercial plant will be $250 to $300 million, which we anticipate will be funded from a combination of non-recourse debt and equity
capital. We and BP recently filed a joint application for a Department of Energy (DOE) loan guarantee program. On June 25, 2009, we announced our application had been selected by the DOE to enter the due diligence phase of its
Title XVII Loan Guarantee Program. If awarded, funding from this program could cover as much as 80% of the total cost of construction of the project, although we expect this program would fund 60% to 70% of the cost of construction. We expect
the remaining 30% to 40% to be funded by equal project equity investments from BP and us. This may require us to raise project equity capital of up to $60 million in addition to the cash required to fund our ongoing operations.

We believe that we will be successful in generating additional cash to fund our operations through a combination of additional corporate partnerships and
collaborations, federal, state and local grant funding, incremental product sales, selling or financing assets, and, if necessary and available, the sale of equity or debt securities. If we are unsuccessful in raising additional capital from any of
these sources, we may need to defer, reduce or eliminate certain planned expenditures.

There can be no assurance that we will be able to obtain any sources of financing on acceptable terms, or
at all. If we are not able to defer, reduce or eliminate our expenditures, secure additional sources of revenue or otherwise secure additional funding, we may need to restructure or significantly curtail our operations, divest all or a portion of
our business, file for bankruptcy or cease operations.

2007 Convertible Notes Offering

In March and April 2007 we completed an offering of $120 million aggregate principal amount of the 2007 Notes in a private placement, generating net cash
proceeds to us of approximately $114.8 million. The 2007 Notes have been registered under the Securities Act of 1933, as amended, to permit registered resale of the 2007 Notes and of the common stock issuable upon conversion of the 2007 Notes. As
more fully described below, $18.5 million in face value of the 2007 Notes was exchanged for new debt pursuant to the issuance of our 2008 Notes. As of June 30, 2009, we had $99.5 million in face value outstanding under the 2007 Notes.

The 2007 Notes bear interest at 5.5% per year, payable in cash semi-annually, and are convertible at the option of the holders at any
time prior to maturity, redemption or repurchase into shares of our common stock at a conversion rate of 156.5 shares per $1,000 principal amount of 2007 Notes (subject to adjustment in certain circumstances), which represents a conversion price of
$6.40 per share. In connection with the 2007 Notes offering, we paid $5.2 million in financing charges, which is reflected in other long term assets on the accompanying Condensed Consolidated Balance Sheets, and is being amortized to interest
expense over the initial five-year term of the 2007 Notes using the effective interest method.

2008 Convertible Notes Offering

On February 27, 2008, we completed a private placement of our 2008 Notes and warrants to purchase our common stock. Concurrent
with entering into the purchase agreement, we also entered into senior notes exchange agreements with certain existing holders of our 2007 Notes pursuant to which such noteholders exchanged approximately $18.5 million in aggregate principal amount
of the 2007 Notes for approximately $16.7 million in aggregate principal amount of the 2008 Notes and for warrants to purchase common stock. Including the 2008 Notes issued in exchange for the 2007 Notes, we issued $71 million in aggregate principal
amount of the 2008 Notes and warrants to purchase approximately 8 million shares of our common stock. Gross proceeds from new investments were approximately $54 million and net proceeds from new investments, after giving effect to payment of
certain transaction-related expenses and the cash cost of the convertible hedge transaction described below, were approximately $44 million. On July 1, 2009, we entered into agreements to amend the 2008 Notes, which amendment became effective
on July 6, 2009.

In connection with the amendment, the conversion price for the 2008 Notes was reduced from $2.13 to $1.74 and the
anti-dilution protection included in the 2008 Notes was changed from full ratchet anti-dilution protection to, in most cases, a version of broad-based weighted average anti-dilution protection, subject to certain limitations. In addition, the 2008
Notes are subject to automatic conversion at our option if our closing stock price exceeds $3.48 (formerly $8.18 prior to the amendment) per share over a 30-trading day period ending prior to the date we provide notice of the automatic conversion to
investors, the average daily trading volume of our stock over that 30-trading day period equals or exceeds $3 million, and certain other conditions are met.

We are required to pay interest on the 2008 Notes at the rate of 8% per year, and the 2008 Notes also include a make-whole provision whereby, upon any holders conversion of the 2008 Notes for
common stock, we are obligated to pay such holder an amount equal to the interest foregone over the life of the 2008 Notes based on such conversion, discounted back to the date of conversion using the published yield on two-year U.S. Treasury notes
as the discount rate. The 2008 Notes provide that we may pay interest or make-whole amounts with shares of our common stock at a 5% discount to the applicable stock price at the time of the interest payment or conversion, subject to the
satisfaction of certain conditions. As of June 30, 2009, our potential maximum remaining make-whole obligation assuming conversion of 100% of the 2008 Notes on that date was approximately $7.0 million.

Since inception through June 30, 2009, holders of the 2008 Notes had converted principal in the amount of $41.5 million into approximately
33.8 million shares of our stock, including approximately 17.3 million shares to satisfy a portion of the related make-whole obligations.

During the three and six months ended June 30, 2009, pursuant to current accounting rules, we recorded a gain on debt extinguishment of $2.5 million and $6.1 million, calculated as the difference between the
carrying value of the converted 2008 Notes and the fair value of the shares of common stock delivered to the noteholders upon conversion.

Between July 1, 2009 and August 10, 2009, holders of the 2008 Notes converted an additional principal amount of $11.3 million into approximately 10.8 million shares of our common stock, including approximately
4.3 million shares to satisfy the related make-whole obligations.

The warrants are exercisable for shares of our common
stock. The initial exercise price of the warrants is $4.44 per share. The exercise price and the number of shares of our common stock issuable upon exercise of the warrants is subject to weighted average anti-dilution protection.

##### Table of Contents

In connection with the transactions described above, we entered into a convertible hedge transaction with
a counterparty, which is intended to reduce the potential dilution upon conversion of the 2008 Notes. The convertible hedge transaction is composed of two separate call options. Under the first call option, on April 1, 2012 (or earlier upon
conversion of the 2008 Notes), we are entitled to purchase 13,288,509 shares of our common stock from the counterparty at a price per share equal to the initial conversion price of $4.09 (or a proportion of such number of shares based on the
proportion of the 2008 Notes being converted). Under the second call option, on three exercise dates staggered in six month intervals beginning on October 1, 2013, the counterparty is entitled to purchase an aggregate of 13,288,509 shares of
our common stock at a price per share of $5.16. The cash cost of the convertible hedge transaction was approximately $6.2 million.

During
2008, we used the net proceeds from the sale of our 2008 Notes and warrants for general corporate and working capital purposes, including the completion of construction and commissioning of our cellulosic ethanol demonstration facility.

The following table summarizes our principal and interest obligations for the 2007 and 2008 Notes as of June 30, 2009, assuming such obligations
are not converted prior to maturity (in thousands):

payment date.

Balance Sheet

Our consolidated assets have increased by $3.7 million, to $157.3 million at June 30, 2009 from $153.6 million at December 31, 2008, attributable primarily to the increase in cash from payments received
under our collaboration with BP.

Our consolidated liabilities have decreased by $12.8 million, to $168.5 million at June 30, 2009
from $181.3 million at December 31, 2008, primarily attributable to a decrease in our carrying value of debt, due to additional conversions of the 2008 Notes during the first and second quarters, which resulted in the issuance of
30.0 million shares of our common stock.

Cash Flows Related to Operating, Investing and Financing Activities

Our operating activities used cash of $30.9 million for the six months ended June 30, 2009. Our cash used in operating activities consisted
primarily of cash used to manufacture inventory for our specialty enzyme business, and to fund our efforts in cellulosic ethanol technology process development and commercialization, which was partially offset by proceeds from
BPs capital contributions to Galaxy and Vercipia which are included in financing activities described below.

Our investing
activities used cash of $2.2 million for the six months ended June 30, 2009. Our investing activities included purchases of property, plant and equipment primarily for the start-up and commissioning of our demonstration-scale facility.

During 2007, 2008, and 2009, we (including expenditures by Celunol Corp., with which we merged) spent in excess of $100 million in capital
expenditures for further modifications and improvements to our pilot facility and the construction, start-up, commissioning and optimization of our demonstration-scale cellulosic ethanol facility in Jennings, Louisiana. In early 2009 we achieved a
key development milestone when our 1.4 million gallon per year demonstration-scale cellulosic ethanol facility in Jennings, Louisiana was commissioned. We produced our first gallons of cellulosic ethanol out of the plant. Work to optimize the
facility and make process improvements has commenced as we seek to ensure reliable and cost-effective operation. We will require additional capital and operating expenditures to complete the optimization of our demonstration-scale facility
throughout 2009. We do not have fixed-priced arrangements with our major engineering and construction firms; as such, most of our engineering and construction costs related to our demonstration-facility are incurred and paid on a time and materials
basis. During 2007 and 2008, we incurred significant costs in excess of our projected expenditures for the improvements to our pilot plant and construction of our demonstration-scale facility.

Our financing activities generated net cash of $40.5 million for the six months ended June 30, 2009,
consisting primarily of capital contributions by BP into Galaxy and Vercipia, our two consolidated variable interest entities.

Manufacturing and Supply Agreements

During 2002, we entered into a manufacturing agreement with Fermic to provide us with
the capacity to produce commercial quantities of certain enzyme products. Based on actual and projected increased product requirements, the agreement was amended in 2006 to provide for additional capacity to be installed over the next two years.
Under the terms of the agreement, we can cancel the committed purchases with thirty months notice provided that the term of the agreement, including the termination notice period, aggregates four years. Pursuant to our agreement with Fermic,
we are also obligated to reimburse monthly costs related to manufacturing activities. These costs scale up as our projected manufacturing volume increases. As of June 30, 2009, under this agreement we have made minimum commitments to Fermic of
approximately $43.8 million, over the next three years.

During 2009, we anticipate funding as much as $1.1 million in additional equipment
costs related to our manufacturing agreement with Fermic. As we continue to develop our commercial manufacturing platforms, we may decide to purchase additional capital equipment under this agreement. Since inception through June 30, 2009, we
had incurred costs of approximately $20.7 million for equipment related to this agreement.

Due to capacity constraints at Fermic in 2008
we were not able to supply adequate quantities of Phyzyme necessary to meet the demand from Danisco. As a result, we contracted with Genencor, a subsidiary of Danisco, to serve as a second-source manufacturer for Phyzyme. Our supply agreement with
Danisco for Phyzyme contains provisions which allow Danisco, with six months advance notice, to assume the right to manufacture Phyzyme. If Danisco were to exercise this right, we may experience excess capacity at Fermic. If Danisco assumed the
right to manufacture Phyzyme and we were unable to absorb or otherwise reduce the excess capacity at Fermic with other products, our results of operations and financial condition would be adversely affected.

Bank Debt

On September 30,
2005, we entered into a $14.6 million Loan and Security Agreement (the Bank Agreement) with a commercial bank (the Bank). The Bank Agreement provided for a one-year credit facility for up to $10.0 million in financing
for qualified equipment purchases in the United States and Mexico (the Equipment Advances) and a $4.6 million letter of credit sub-facility (the Letter of Credit Sublimit). The Bank Agreement was amended in October 2006 to
increase the Letter of Credit Sublimit to $4.7 million. Borrowings under the Equipment Advances are structured as promissory notes which are secured by qualified

equipment purchases and repaid over 36 to 48 months, depending on the location of the equipment financed. Borrowings bear interest at the Banks
prime rate (3.25% at June 30, 2009) plus 0.75%. On September 30, 2006, our draw-down period under the Equipment Advances expired.

The Bank Agreement contains standard affirmative and negative covenants and restrictions on actions by us including, but not limited to, activity related to common stock repurchases, liens, investments, indebtedness, and fundamental changes
in, or dispositions of, our assets. We may take certain of these actions with the consent of the Bank.

On February 22, 2008, we
executed an amendment to the Bank Agreement. Pursuant to the amendment, in exchange for the Banks consent to the private placement of our 2008 Notes and warrants, we agreed to expand the scope of the security interest under the loan and
security agreement to include substantially all of our assets excluding our intellectual property. In return, the Bank modified our minimum cash covenant to reduce the required minimum liquidity from $25 million to an amount equal to 150% of the
total amount of our obligations to the Bank under the Bank Agreement.

At June 30, 2009, there was approximately $0.4 million in
outstanding borrowings under the Equipment Advances and a letter of credit for approximately $10.4 million under the Letter of Credit Sublimit, as required under our facilities leases. As further discussed below we have been required to cash secure
the letter of credit with the Bank.

As of June 30, 2009, we were in compliance with all debt covenants under our various financing
agreements.

Pursuant to our facilities leases for our office and laboratory space in San Diego, we are required to maintain a letter of credit on behalf of our landlord in lieu of a cash deposit. The total amount required under the letter of credit is
based on minimum required working capital and market capitalization. As of June 30, 2009, we had a letter of credit in place pursuant to this agreement for approximately $10.4 million, representing the $100,000 minimum and approximately 24
months current rent. The letter of credit is issued under our existing Bank Agreement as described above. We are required by the Bank to secure this obligation with cash, which is reflected as restricted cash on our Condensed Consolidated
Balance Sheets as of June 30, 2009.

Off-Balance Sheet Arrangements

We do not have any off-balance sheet arrangements that would give rise to additional material contractual obligations as of June 30, 2009.

Critical Accounting Policies

Our
discussion and analysis of our financial condition and results of operations is based upon our consolidated financial statements, which have been prepared in accordance with U.S. generally accepted accounting principles. The preparation of these
consolidated financial statements requires management to make estimates and judgments that affect the reported amounts of assets, liabilities, revenue and expenses, and related disclosures. On an ongoing basis, we evaluate these estimates, including
those related to revenue recognition, long-lived assets, accrued liabilities, convertible senior notes, and income taxes. These estimates are based on historical experience, information received from third parties, and on various other assumptions
that are believed to be reasonable under the circumstances, the results of which form the basis for making judgments about the carrying values of assets and liabilities that are not readily apparent from other sources. Actual results may differ from
these estimates under different assumptions or conditions.

We believe the following critical accounting policies affect the significant
judgments and estimates used in the preparation of our consolidated financial statements.

Revenue Recognition

We follow the provisions as set forth by current accounting rules, which primarily include SAB 104 and EITF 99-19.

We generally recognize revenue when we have satisfied all contractual obligations and we are reasonably assured of collecting the resulting receivable.
We are often entitled to bill our customers and receive payment from our customers in advance of recognizing the revenue under current accounting rules. In those instances where we have billed our customers or received payment from our customers in
advance of recognizing revenue, we include the amounts in deferred revenue on our balance sheet.

We generate revenue from research
collaborations generally through funded research, up-front fees to initiate research projects, fees for exclusivity in a field, and milestones. We recognize revenue from research funding on a proportional performance basis, as research
hours are incurred under each agreement. We recognize fees to initiate research over the life of the project. We recognize revenue from exclusivity fees over the period of exclusivity. Our collaborations often include contractual milestones. When we
achieve these milestones, we are entitled to payment, as defined by the underlying agreements. We recognize revenue for milestone payments when earned, as evidenced by written acknowledgement from the collaborator, provided that (i) the
milestone event is substantive and its achievability was not reasonably assured at the inception of the agreement, (ii) the milestone represents the culmination of an earnings process, (iii) the milestone payment is non-refundable and
(iv) our past research and development services,

##### Table of Contents

as well as our ongoing commitment to provide research and development services under the collaboration, are charged at fees that are comparable to the fees
that the we customarily charge for similar research and development services.

We recognize revenue from grants as related costs are
incurred, as long as such costs are within the funding limits specified by the underlying grant agreements.

We recognize revenue related
to the sale of our inventory as we ship or deliver products, provided all other revenue recognition criteria have been met. We recognize revenue from products sold through distributors or other third-party arrangements upon shipment of the products,
if the distributor has a right of return, provided that (a) the price is substantially fixed and determinable at the time of sale; (b) the distributors obligation to pay us is not contingent upon resale of the products;
(c) title and risk of loss passes to the distributor at time of shipment; (d) the distributor has economic substance apart from that provided by us; (e) we have no significant obligation to the distributor to bring about resale of the
products; and (f) future returns can be reasonably estimated. For any sales that do not meet all of the above criteria, revenue is deferred until all such criteria have been met. We include our profit-sharing revenues in product revenues on the
statement of operations. We recognize profit-sharing revenues during the quarter in which such profit sharing revenues are earned based on calculations provided by our profit-sharing partner. To date, we have generated a substantial portion of our
product revenues, including profit-sharing revenues, through our agreements with Danisco.

We sometimes enter into revenue arrangements
that include the delivery of more than one product or service. In these cases, we recognize revenue from each element of the arrangement as long as we are able to determine a separate value for each element, we have completed our obligation to
deliver or perform on that element and we are reasonably assured of collecting the resulting receivable.

We have contracted with Genencor,
a subsidiary of Danisco, to serve as a second-source manufacturer of Phyzyme. Under EITF 99-19, product manufactured for us by Genencor is recognized on a net basis equal to the net profit share received from Danisco, as all the following indicators
of reporting net are met: i) the third party is the obligor; ii) the amount earned is fixed; and iii) the third party maintains inventory risk, as compared to the full value of the manufacturing costs plus profit share we currently recognize for
Phyzyme we manufacture.

Share-based Compensation

Effective January 1, 2006, we calculate the fair value of all share-based payments to employees and non-employee directors, including grants of stock options, non-restricted and restricted shares, and awards
issued under the employee stock purchase plan, and amortize these fair values to share-based compensation in the income statement over the respective vesting periods of the underlying awards.

Share-based compensation related to stock options includes the amortization of the fair value of options at the date of grant determined using
Black-Scholes Merton (BSM) valuation model. We amortize the fair value of options to expense over the vesting periods of the underlying options.

Share-based compensation related to awards issued under our employee stock purchase plan, or ESPP, after December 31, 2005 are based on calculations of fair value under the BSM valuation model which are similar
to how stock option valuations are made. We amortize the fair value of ESPP awards to expense over the vesting periods of the underlying awards.

We estimate the fair value of stock option awards and awards under the ESPP on the date of grant using assumptions about volatility, expected life of the awards, risk-free interest rate, and dividend yield rate. The expected volatility in
this model is based on the historical volatility of our common stock and an analysis of our peers. The risk-free interest rate is based on the U.S. Treasury yield curve in effect at the time awards are granted, based on maturities which approximate
the expected life of the options. The expected life of the options granted is estimated using the historical exercise behavior of employees and an analysis of our peers. The expected dividend rate takes into account the absence of any historical
payments and managements intention to retain all earnings for future operations and expansion.

We estimate the fair value of
non-restricted and restricted stock awards based upon the closing market price of our common stock at the date of grant. We charge the fair value of non-restricted awards to share-based compensation upon grant. We amortize the fair value of
restricted awards to share-based compensation expense over the vesting period of the underlying awards.

Convertible Debt and Derivative Accounting

We account for our 2008 Notes in accordance with APB 14-1. We adopted APB 14-1 on January 1, 2009. It significantly impacts the
accounting for our 2008 Notes by requiring us to account separately for the liability and equity components of the convertible debt. The liability component is measured so the effective interest expense associated with the convertible debt reflects
the issuers borrowing rate at the date of issuance for similar debt instruments without the conversion feature. The difference between the cash proceeds associated with the convertible debt and this estimated fair value is recorded as a debt
discount and amortized to interest expense over the life of the convertible debt.



43



---

##### Table of Contents

Determining the fair value of the liability component requires the use of accounting estimates and
assumptions. These estimates and assumptions are judgmental in nature and could have a significant impact on the determination of the liability component and, in effect, the associated interest expense. According to the guidance, the carrying amount
of the liability component is determined by measuring the fair value of a similar liability that does not have an associated equity component. If no similar liabilities exist, estimates of fair value are primarily determined using assumptions that
market participants would use in pricing the liability component, including market interest rates, credit standing, yield curves and volatilities.

We perform an assessment of all embedded features of a debt instrument to determine if 1) such features should be bifurcated and separately accounted for, and, 2) if bifurcation requirements are met, whether such features should be
classified and accounted for as equity or liability. The fair value of the embedded feature is measured initially, included as a liability on the balance sheet, and remeasured each reporting period. Any changes in fair value are recorded in the
statement of operations. We monitor, on an ongoing basis, whether events or circumstances could give rise to a change in our classification of embedded features.

We account for the conversion of our 2008 Notes in accordance with SFAS 140. SFAS 140 states that upon conversion the difference between the carrying value of the converted 2008 Notes and the fair value of the common
stock delivered to the noteholders is recorded as a gain (loss) on debt extinguishment in the statement of operations.

Variable
Interest Entities

We have implemented the provisions of FIN 46R, which addresses consolidation by business enterprises of variable
interest entities either: (1) that do not have sufficient equity investment at risk to permit the entity to finance its activities without additional subordinated financial support, or (2) in which the equity investors lack an essential
characteristic of a controlling financial interest.

We have entered into a strategic collaboration with BP which includes two special
purpose entities, Galaxy and Vercipia, both of which are jointly owned by BP and us.

We have determined, pursuant to FIN 46R, that both
Galaxy and Vercipia qualify as variable interest entities and that we are the primary beneficiary of both entities. Because we are the primary beneficiary, Galaxy and Vercipia are therefore subject to consolidation by us. As a result, BPs
capital contributions are recorded as noncontrolling interests in consolidated entities on our Condensed Consolidated Balance Sheets. We consolidate the operating results of Galaxy and Vercipia, and record an adjustment to the noncontrolling
interests in consolidated entities for BPs share of profits and/or losses in these entities.

Long-Lived Assets

We review long-lived assets, including leasehold improvements, property and equipment, and acquired intangible assets for impairment whenever events or
changes in business circumstances indicate that the carrying amount of the assets may not be fully recoverable. This requires us to estimate future cash flows related to these assets. Actual results could differ from those estimates, which may
affect the carrying amount of assets and the related amortization expense.

Income Taxes

Effective in 2007, we account for income taxes pursuant to FASB issued Interpretation No. 48, Accounting for Uncertainty in Income
TaxesAn Interpretation of FASB Statement No. 109 (FIN 48). FIN 48 prescribes a recognition threshold and measurement attributes for financial statement disclosure of tax positions taken or expected to be taken
on our tax return. Under FIN 48, we do not recognize an uncertain tax position as a deferred tax asset if it has less than a 50% likelihood of being sustained.

We adopted the provisions of FIN 48 on January 1, 2007, and commenced analyzing filing positions in all of the federal and state jurisdictions where we are required to file income tax returns, as well as all open
tax years in these jurisdictions. As a result of adoption, we have recorded no additional tax liability. As of June 30, 2009 we have not yet completed our analysis of our deferred tax assets. As such, we have removed these
amounts and the offsetting valuation allowance has been removed from our deferred tax assets. We are in the process of completing a Section 382 analysis regarding the limitation of the net operating loss and research and development
credits.

We record a valuation allowance to reduce our deferred tax assets to the amount that is more likely than not to be realized.
While we have considered future taxable income and ongoing tax planning strategies in assessing the need for the valuation allowance, in the event we were to determine that we would be able to realize our deferred tax assets in the future in excess
of their net recorded amounts, an adjustment to the deferred tax assets would increase our income in the period such determination was made. Likewise, should we determine that we would not be able to realize all or part of our net deferred tax
assets in the future, an adjustment to the deferred tax assets would be charged to income in the period such determination was made. Our deferred tax assets at June 30, 2009 were fully offset by a valuation allowance.

Inventories

We value inventory at the lower of cost (first in, first out) or market value and, if necessary, reduce the value by an estimated allowance for excess and obsolete inventories. The determination of the need for an
allowance is based on our review of inventories on hand compared to estimated future usage and sales, as well as judgments, quality control testing data, and assumptions about the likelihood of obsolescence.

Capitalized Interest

We capitalize
interest on capital projects, namely our cellulosic ethanol demonstration facility, commencing with the first expenditure for the project and continuing until the project is substantially complete and placed in service. We amortize the capitalized
interest to depreciation expense using the straight-line method over the same lives as the related assets.



|ITEM 3. | QUANTITATIVE AND QUALITATIVE DISCLOSURES ABOUT MARKET RISK.
|------- | -----------------------------------------------------------

Our exposure to market risk is limited to interest rate risk and, to a lesser extent, foreign currency risk. Our exposure as of the end of the latest fiscal year is described in Part II, Item 7A of our annual report on Form 10-K for
the year ended December 31, 2008.

Interest Rate Exposure

As of June 30, 2009, we had outstanding debt obligations at face value of $129.4 million, including $99.5 million of 2007 Notes, $29.5 million of 2008 Notes, and $0.4 million of equipment loans payable. As
of June 30, 2009, the fair value of our 2007 Notes was approximately $17.0 million and the fair value of our 2008 Notes was approximately $13.9 million.

Foreign Currency Exposure

We engage third parties, including Fermic, our contract manufacturing partner in Mexico City, to
provide various services. From time to time certain of these services result in obligations that are denominated in other than U.S. dollars. Foreign currency risk is minimized because the amount of such obligations is not material.



|ITEM 4. | CONTROLS AND PROCEDURES.
|------- | ------------------------

Evaluation of Disclosure Controls and
Procedures

We maintain disclosure controls and procedures that are designed to ensure that information required to be disclosed in our
Exchange Act reports is recorded, processed, summarized and reported within the timelines specified in the SECs rules and forms, and that such information 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.

Under the supervision and with the
participation of our management, including our Chief Executive Officer and our Chief Financial Officer, we carried out an evaluation of the effectiveness of our disclosure controls and procedures (as such term is defined in SEC Rules 13a-15(e) and
15d-15(e)) as of June 30, 2009. Based on such evaluation, such officers have concluded that, as of June 30, 2009, our disclosure controls and procedures were effective.

There were no changes in our internal controls over financial reporting (as defined in Rule 13a-15(f) of the Exchange Act) that occurred during
our most recent fiscal quarter that have materially affected, or are reasonably likely to materially affect, our internal controls over financial reporting.

All internal control systems, no matter how well designed, have inherent limitations. Therefore, even those systems determined to be effective can provide only reasonable assurance with respect to financial statement
preparation and presentation. Management continues to improve the design and effectiveness of our disclosure controls and procedures and internal control over financial reporting and intends to continue to implement improvements in its internal
control over financial reporting and hire additional finance and accounting personnel as necessary to prevent or detect deficiencies, and to timely address any deficiencies that we may identify in the future.

PART IIOTHER INFORMATION



|ITEM 1. | LEGAL PROCEEDINGS.
|------- | ------------------

Class Action Shareholder Lawsuit

In June 2004, the Company executed a formal settlement agreement with the plaintiffs in a class action lawsuit filed in December 2002
in a U.S. federal district court (the Court). This lawsuit is part of a series of related lawsuits in which similar complaints were filed by plaintiffs against hundreds of other public companies that conducted an Initial Public Offering
(IPO) of their common stock in 2000 and the late 1990s (the IPO Cases). On February 15, 2005, the Court issued a decision certifying a class action for settlement purposes and granting preliminary approval of the
settlement subject to modification of certain bar orders contemplated by the settlement. On August 31, 2005, the Court reaffirmed class certification and preliminary approval of the modified settlement. On April 24, 2006, the Court held a
Final Fairness Hearing to determine whether to grant final approval of the settlement. On December 5, 2006, the Second Circuit Court of Appeals vacated the lower Courts earlier decision certifying as class actions the six IPO Cases
designated as focus cases. The Company is not one of the six focus cases. Thereafter, the District Court ordered a stay of all proceedings in all of the IPO Cases pending the outcome of the plaintiffs petition to the Second Circuit
for rehearing en banc and resolution of the class certification issue. On April 6, 2007, the Second Circuit denied plaintiffs rehearing petition, but clarified that the plaintiffs may seek to certify a more limited class in the District
Court. Accordingly, the settlement as originally negotiated was terminated pursuant to stipulation of the parties and will not be finally approved. On or about August 14, 2007, Plaintiffs filed amended complaints in the six focus cases, and
thereafter moved for certification of the classes and appointment of lead plaintiffs and lead counsel in those cases. The six focus case issuers filed motions to dismiss the claims against them in November 2007 and an opposition to plaintiffs
motion for class certification in December 2007. The Court denied the motions to dismiss on March 16, 2008. On October 2, 2008, the plaintiffs withdrew their class certification motion. On February 25, 2009, liaison counsel for
plaintiffs informed the district court that a settlement of the IPO Cases had been agreed to in principle, subject to formal approval by the parties and preliminary and final approval by the court. On April 2, 2009, the parties submitted a
tentative settlement agreement to the court and moved for preliminary approval thereof. On June 11, 2009, the Court granted preliminary approval of the tentative settlement, ordered that notice of the settlement to be published and mailed, and
set a Final Fairness Hearing for September 10, 2009. If approved, the settlement would result in the dismissal of all claims against the Company and its officers and directors with prejudice, and the Companys pro rata share of the
settlement fund will be fully funded by insurance.

The Company is covered by a claims-made liability insurance policy which it believes
will satisfy any potential liability of the Company under this settlement. Due to the inherent uncertainties of litigation, and because the settlement has not yet been finally approved by the Court, the ultimate outcome of this matter cannot be
predicted.

Noteholder Lawsuit

On
April 30, 2009, Capital Ventures International (CVI), a holder of the 2008 Notes, filed a lawsuit against the Company in the United States District Court for the Southern District of New York alleging that the Company breached the
terms of the 2008 Notes by processing certain conversion notices submitted to the Company by CVI at $2.13 (and, with the recent amendment of the 2008 Notes, $1.74) per share, rather than $1.47 per share, asserting that CVI is entitled to additional
shares based on the applicable conversions, as well as damages, and requesting a declaratory judgment that $1.47 per share is the conversion price for the 2008 Notes. On June 3, 2009, CVI amended its complaint to also request a declaratory
judgment that the Company cannot amend the 2008 Notes, pursuant to their terms, without the consent of each affected noteholder. The Company filed its answer to CVIs amended complaint on June 30, 2009, denying all material allegations of
the complaint. An initial pre-trial conference is scheduled for August 11, 2009.

Between February 27, 2009 through
August 10, 2009, the holder has converted approximately $11.25 million in face value, and the Company has issued approximately 11.3 million shares to settle these conversions and related make-whole obligations at $2.13 or,
following the recent amendment of the 2008 Notes, $1.74 per share. Assuming a conversion price of $1.47, 1.7 million additional shares would be issuable in connection with these conversions. If the Company were to be found to have not satisfied
its obligations under the 2008 Notes, because the Company processed the applicable conversion notices at the wrong conversion price, the Company could, among other negative consequences, be required to redeem the 2008 Notes in whole or in part. The
Company does not believe that this lawsuit will have a material impact on its financial statements.

In accordance with SFAS No. 5,
Accounting for Contingencies the Company believes any contingent liabilities related to these claims are not probable or estimable and therefore no amounts have been accrued in regards to these matters.

In addition to the matter noted above, from time to time, the Company is subject to legal proceedings, asserted claims and investigations in the ordinary
course of business, including commercial claims, employment and other matters, which management considers to be immaterial, individually and in the aggregate. In accordance with generally accepted accounting principles, the Company makes a provision
for a liability when it is both probable that a liability has been incurred and the amount of the loss can be reasonably estimated. These provisions are reviewed at least quarterly and adjusted to reflect the impacts of negotiations, settlements,

rulings, advice of legal counsel and other information and events pertaining to a particular case. Litigation is inherently unpredictable. However, the
Company believes that it has valid defenses with respect to the legal matters pending against the Company. It is possible, nevertheless, that the Companys consolidated financial position, cash flows or results of operations could be negatively
affected by an unfavorable resolution of one or more of such proceedings, claims or investigations.



|ITEM 1A. | RISK FACTORS
|-------- | ------------

Except for the historical information contained
herein, this quarterly report on Form 10-Q contains forward-looking statements that involve risks and uncertainties. Our actual results may differ materially from those discussed here. Factors that could cause or contribute to differences in our
actual results include those discussed in the following section, as well as those discussed in Part I, Item 2 entitled Managements Discussion and Analysis of Financial Condition and Results of Operations and elsewhere
throughout this quarterly report on Form 10-Q. You should consider carefully the following risk factors, together with all of the other information included in this quarterly report on Form 10-Q. Each of these risk factors could adversely affect our
business, operating results, and financial condition, as well as adversely affect the value of an investment in our common stock.

We have marked with an asterisk those risk factors that reflect substantive changes from the risk factors previously discussed in our Form 10-K for the year ended December 31, 2008.

Risks Applicable to Our Business Generally

We should be
viewed as an early stage company with new and unproven technologies

You must evaluate our business in light of the uncertainties and
complexities affecting an early stage biotechnology company or cellulosic ethanol manufacturing company. Our existing proprietary technologies are new and in the early stage of development for both biofuels and specialty enzymes. We may not be
successful in the commercial development of these or any further technologies, products or processes. Successful products and processes require significant development and investment, including testing, to demonstrate their cost- effectiveness prior
to regulatory approval and commercialization. To date, we have commercialized 12 of our own products, all in the specialty enzymes area, including our Purifine, Fuelzyme, and Luminase enzymes. In addition, four of our collaborative partners,
Invitrogen Corporation, Danisco Animal Nutrition, Givaudan Flavors Corporation, and Syngenta Animal Nutrition (formerly known as Zymetrics, Inc.), have incorporated our technologies or inventions into their own commercial products from which we have
generated and/or can generate royalties. We have not yet commercialized any products or processes related to our biofuels segment. Our specialty enzyme products and technologies have only recently begun to generate significant revenues. Because of
these uncertainties, our discovery process may not result in the identification of product candidates or biofuels production processes that we or our collaborative partners will successfully commercialize. If we are not able to use our technologies
to discover new materials, products, or processes with significant commercial potential, or if we are unable to sell our cellulosic ethanol or an integrated solution for the production of cellulosic ethanol, we will continue to have significant
losses in the future due to ongoing expenses for research, development and commercialization efforts and we may be unable to obtain additional funding to fund such efforts.

* We have a history of net losses, we expect to continue to incur net losses, and we may not achieve or maintain profitability.

As of June 30, 2009, we had a working capital deficit of $16.8 million, and an accumulated deficit of approximately $630.2 million. We expect to continue to incur additional losses for the foreseeable future.

Product revenues currently account for the majority of our annual revenues, and we expect that a significant portion of our revenue for
2009 will result from the same source as well as from grant revenue. Future revenue from collaborations is uncertain and will depend upon our ability to maintain our current collaborations, enter into new collaborations and to meet research,
development, and commercialization objectives under new and existing agreements, and we have been de-emphasizing collaborations that are not core to our strategic market focus. Over the past two years, our product revenue in absolute dollars and as
a percentage of total revenues has increased significantly, and our grant revenue in absolute dollars and as a percentage of total revenues has increased significantly during 2009. Our product and grant revenue may not continue to grow in either
absolute dollars or as a percentage of total revenues. If product revenue increases, we would expect sales and marketing expenses to increase in support of increased volume. Additionally, as our business model develops, our general and
administrative expenses might increase based on broadening our infrastructure to support continued growth in the business. In addition, the amounts we spend will impact our ability to become profitable and this will depend, in part, on:



| |  |  | the progress of our research and development programs for the production of ethanol from various sources of cellulosic biomass;
| | - |  | -------------------------------------------------------------------------------------------------------------------------------



| |  |  | the cost of building, operating and maintaining research and production facilities;
| | - |  | -----------------------------------------------------------------------------------



| |  |  | the number of production facilities that we ultimately attempt to develop;
| | - |  | --------------------------------------------------------------------------

##### Table of Contents

| |  |  | the time and expense required to prosecute, enforce and/or challenge patent and other intellectual property rights;
| | - |  | -------------------------------------------------------------------------------------------------------------------



| |  |  | how competing technological and market developments affect our proposed activities; and
| | - |  | ---------------------------------------------------------------------------------------



| |  |  | the cost of obtaining licenses required to use technology owned by others for proprietary products and otherwise.
| | - |  | -----------------------------------------------------------------------------------------------------------------

We may not achieve any or all of our goals and, thus, we cannot provide assurances that we will ever be profitable on an operating basis or maintain
revenues at current levels. If we fail to achieve profitability and maintain or increase revenues, the market price of our common stock will likely decrease.

Even if we generate significant additional revenue in our specialty enzymes business, we do not expect to achieve overall profitability for the foreseeable future, as we make additional investments to implement our
vertical integration strategy within biofuels. In order for us to generate revenue, we must not only retain our existing collaborations and/or attract new ones and achieve milestones under them, but we must also develop products or technologies that
we or our partners choose to commercialize and that are commercially successful and from which we can derive revenue through sales or royalties. Even if we do achieve profitability, we may not be able to sustain or increase profitability on a
quarterly or annual basis.

* We continue to experience losses from operations, and we may not be able to fund our operations and continue as a going
concern.

The report of our independent registered public accounting firm for the fiscal year ended December 31, 2008 contains an
explanatory paragraph which states that we have incurred recurring losses from operations and, based on our operating plan and existing working capital deficit, this raises substantial doubt about our ability to continue as a going concern. We have
an accumulated deficit of $630.2 million and working capital deficit of $16.8 million as of June 30, 2009.

We have used the proceeds
received from sales of our 2007 Notes in April 2007 and 2008 Notes in February 2008 to make enhancements to our pilot facility, to complete construction and commissioning of our demonstration-scale facility in Jennings, Louisiana, to advance
development of the site for our first commercial cellulosic ethanol plant, to commercialize our specialty enzymes products, to continue our research and development efforts in both specialty enzymes and biofuels, and for expenses related to the
merger with Celunol, all of which have adversely affected, and will continue to adversely affect, our operating results until revenues reach levels at which we can fully support our operating and capital expenditures.

We will require additional capital to fund our operations, including substantial capital to fund the first commercial cellulosic ethanol plant with BP,
which we estimate will cost as much as $300 million to complete. We believe that we will be successful in raising or generating additional cash to fund these requirements through a combination of additional corporate partnerships and collaborations,
federal, state and local grant funding, selling and financing assets, incremental product sales, and, if necessary and available, the sale of equity or debt securities. There can be no assurance that we will be able to obtain any sources of
financing on acceptable terms, or at all. If we are unsuccessful in raising additional capital from any of these sources, we may need to defer, reduce or eliminate certain planned expenditures.

If we are not able to reduce or defer our expenditures, secure additional sources of revenue or otherwise secure additional funding, we may be unable to
continue as a going concern, and we may be forced to restructure or significantly curtail our operations, file for bankruptcy or cease operations.

* We
will need additional capital in the future. If additional capital is not available, we may have to curtail or cease operations.

We
will need to raise more money to continue to fund our business. Our capital requirements will depend on several factors, including:



| |  |  | Expenditures and investments to implement our biofuels business strategy, including increased capital expenditures in relation to such strategy, for example, to
optimize our demonstration-scale facility, and build our commercial-scale facilities;
| | - |  | ------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------



| |  |  | The level of research and development investment required to maintain our technology leadership position;
| | - |  | ---------------------------------------------------------------------------------------------------------



| |  |  | Our ability to enter into new agreements with collaborative partners or to extend the terms of our existing collaborative agreements, and the terms of any agreement
of this type;
| | - |  | ----------------------------------------------------------------------------------------------------------------------------------------------------------------------------------



| |  |  | The success rate of our discovery efforts associated with milestones and royalties;
| | - |  | -----------------------------------------------------------------------------------



| |  |  | Our ability to successfully commercialize products developed independently and the demand for such products;
| | - |  | ------------------------------------------------------------------------------------------------------------



| |  |  | The timing and willingness of strategic partners and collaborators to commercialize our products that would result in royalties;
| | - |  | --------------------------------------------------------------------------------------------------------------------------------



| |  |  | Costs of recruiting and retaining qualified personnel; and
| | - |  | ----------------------------------------------------------



| |  |  | Our possible acquisition or licensing of complementary technologies or acquisition of complementary businesses.
| | - |  | ---------------------------------------------------------------------------------------------------------------

##### Table of Contents

We may seek additional funds through a combination of existing and additional corporate partnerships and
collaborations, federal, state and local grant funding and loan guarantees, product sales, selling or financing assets, and the sale of equity or debt securities. In addition, we expect to attempt to raise funds in the non-recourse, project-finance
capital markets to finance growth of our project portfolio. Such funds may not be available to us or may be available on terms not satisfactory to us. We currently have applications pending for federal, state and local financial incentives such as
grants; however, such funds may not be available to us in adequate amounts, if at all. An inability to raise adequate funds to support the growth of our project portfolio will materially adversely affect our business.

If we cannot raise more money, we will have to implement one or more of the following remedies:



| |  |  | reduce our capital expenditures;
| | - |  | --------------------------------



| |  |  | further scale back our development of new enzyme products;
| | - |  | ----------------------------------------------------------



| |  |  | scale back our efforts to commercialize cellulosic ethanol;

If the recent
volatility in the United States and global equity and credit markets and the decline in the general world economy continue for an extended period of time, it may become more difficult to raise money in the public and private markets and harm our
financial condition and results of operations.

The United States and global equity markets have recently been extremely volatile and
unpredictable, reflecting in part a general concern regarding the global economy. This volatility in the market affects not just our stock price, but also the stock prices of our collaborators. In addition, this volatility has also affected the
ability of businesses to obtain credit and to raise money in the capital markets. If we or our collaborators are unable to obtain credit or raise money in the capital markets, we may not be able to continue to fund our current research and
development projects, fund our current products, raise project finance capital for the development of commercial cellulosic ethanol plants, or otherwise continue to maintain or grow our business.

We may not have adequate funds to pay interest on our 2007 Notes, or to purchase the 2007 Notes on required purchase dates or upon a fundamental change.

In April 2007, we completed the sale of $120 million of 2007 Notes, the terms of which include provisions whereby on each of
April 1, 2012, April 1, 2017 and April 1, 2022, holders of the 2007 Notes may require us to purchase, for cash, all or a portion of their 2007 Notes at 100% of their principal amount, plus any accrued and unpaid interest up to,
but excluding, that date. As of June 30, 2009, $99.5 million of the 2007 Notes remains outstanding. The 2007 Notes also require us to pay interest at the rate of 5.5% per year in cash. If a fundamental change, which is defined
in the indenture related to the 2007 Notes, occurs, holders of the 2007 Notes may require us to repurchase, for cash, all or a portion of their 2007 Notes. We may not have sufficient funds to pay the interest, purchase price or repurchase price of
the 2007 Notes when due. In addition, the terms of any borrowing agreements which we may enter into from time to time may require early repayment of borrowings under circumstances similar to those constituting a fundamental change. For
example, the holders of the 2008 Notes may require us to redeem the 2008 Notes under such circumstances. Those agreements may also make our repurchase of 2007 Notes an event of default under the agreements. If we fail to pay interest on the 2007
Notes or to purchase or repurchase the 2007 Notes when required, we will be in default under the indenture for the 2007 Notes, which would also cause an event of default under the 2008 Notes and may also cause an event of default under the terms of
other borrowing arrangements that we may enter into from time to time. Any of these events could have a material adverse effect on our business, results of operations and financial condition, up to and including causing us to cease operations
altogether.

* We may not have adequate funds to pay interest or make-whole payments on our 8% Senior Convertible Notes, or 2008 Notes, or
to purchase the 2008 Notes at required times.

In February 2008, we completed a private placement of $71 million of 2008 Notes and
warrants to purchase our common stock. As of August 10, 2009, approximately $18.2 million of the 2008 Notes remains outstanding.

We
are required to pay interest on the 2008 Notes at the rate of 8% per year, and the 2008 Notes also include a make-whole provision whereby, upon any holders conversion of the 2008 Notes for common stock, we are obligated to pay
such holder an amount equal to the interest foregone over the life of the 2008 Notes based on such conversion, discounted back to the date of conversion using the published yield on two-year U.S. Treasury notes as the discount rate. The 2008 Notes
provide that we may, subject to the satisfaction of certain conditions, pay interest or make-whole amounts with shares of our common stock at a 5% discount to the

##### Table of Contents

applicable stock price at the time of the interest payment or conversion. As of August 10, 2009, our potential maximum remaining make-whole
obligation assuming conversion of 100% of the 2008 Notes on that date was approximately $3.9 million, which we may be required to settle in cash if we are unable to satisfy the conditions for paying make-whole amounts with shares or the
noteholders do not otherwise waive these conditions. Were many holders of our 2008 Notes to convert their 2008 Notes, or if a significant amount were converted at approximately the same time, and we were at that time unable to satisfy the conditions
for paying make-whole amounts in shares and the noteholders did not otherwise waive those conditions, our cash resources at that time could be insufficient to make the required make-whole payments. Also, one holder of 2008
Notes has asserted that certain make-whole payments made to it in shares should have been paid in cash, and has filed a lawsuit against us asserting a conversion price of $1.47, rather than $2.13, for a portion of its 2008 Notes for
which it has submitted conversion notices. The lawsuit requests additional shares based on such conversions, damages and declaratory relief. We have disputed the assertions made by that noteholder and believe our positions are correct. However, if
we were found to have been required to pay such make-whole payments in cash, or were found to have otherwise not satisfied our obligations under the 2008 Notes, we could, among other negative consequences, be required to redeem some or
all of the 2008 Notes. The holders of the 2008 Notes may also require us to redeem their 2008 Notes in connection with certain change of control events, and any borrowing agreements which we may enter into from time to time may similarly
require early repayment of borrowings under circumstances like those constituting a change of control under the terms of the 2008 Notes. For example, the holders of the 2007 Notes may require us to repurchase, for cash, all or a portion
of the 2007 Notes in such circumstances. Those agreements may also make our repurchase of 2008 Notes an event of default under the agreements. We may not have sufficient funds to pay any required cash interest or cash make-whole payments
or repurchase or redemption amounts of the 2008 Notes when due, or any amounts due under other borrowing agreements at the same time such amounts are due under the 2008 Notes or otherwise, and any default under the 2008 Notes or any other borrowing
agreements (including the 2007 Notes) could cause events of default under our other debt obligations (including the 2008 Notes and the 2007 Notes, as applicable). Any of these events could cause the maturity of some or all of our debt obligations
(including the 2008 Notes and the 2007 Notes, as applicable) to be accelerated, and could have a material adverse effect on our business, results of operations and financial condition, up to and including causing us to cease operations.

*Conversion of the 2008 Notes and/or the 2007 Notes, exercise of related warrants, anti-dilution adjustments that may occur under the 2008 Notes and/or the related
warrants, and the issuance of shares of common stock in payment of interest or make-whole payments under the 2008 Notes will dilute the ownership interest of existing stockholders.

The conversion or exercise of some or all of the 2007 Notes and/or the 2008 Notes and related warrants, and the issuance of shares of common stock in
payment of interest or make-whole payments under the 2008 Notes, could significantly dilute the ownership interests of existing stockholders. In April 2008, the conversion price of the 2007 Notes decreased from $8.16 per share to $6.40
per share, based on a re-set provision contained in the 2007 Notes. In February 2009, the conversion price of the 2008 Notes decreased from $4.09 per share to $2.13 per share, based on a re-set provision contained in the 2008 Notes, and in July 2009
decreased further to $1.74 per share in connection with the amendment of the 2008 Notes. These re-sets and other reductions in the applicable conversion prices for the 2007 Notes and the 2008 Notes have caused, and will continue to cause, additional
shares to be issued upon conversion of these instruments compared to the number of shares initially issuable upon such conversions.

The
2008 Notes also contain a version of broad-based weighted average anti-dilution protection, subject to certain exceptions and limitations, which could cause further reductions in the $1.74 conversion price for the 2008 Notes should we engage in
subsequent issuances that trigger those provisions. One holder of the 2008 Notes has filed a lawsuit against us asserting a conversion price of $1.47, rather than $2.13 (and with the recent amendment of the 2008 Notes, $1.74), for a portion of its
2008 Notes for which it has submitted conversion notices. We have disputed this assertion and believe our position is correct. If we were required to honor those conversion notices or future conversion notices at the lower conversion price, that
would cause additional shares to be issued. Additionally, the warrants related to the 2008 Notes and certain warrants held by Syngenta contain weighted average anti-dilution protection that could also cause more shares to become issuable under those
warrants if we engage in subsequent issuances that trigger those provisions. In addition, given the low recent values for our stock price, to the extent we satisfy required interest or make-whole payments under the 2008 Notes by issuing
shares, which we intend to do to the extent permissible under the terms of the 2008 Notes, including to the extent we obtain waivers from the holders to do so, we will be issuing relatively more shares than if our stock price was at a higher level.
For example, in connection with the conversion of $40.7 million in aggregate principal amount of 2008 Notes that occurred between January 1, 2009 and August 10, 2009, we issued approximately 20.8 million shares in partial satisfaction
of the related make-whole obligations. Sales in the public market of the common stock issuable upon conversion of the 2007 Notes and/or 2008 Notes or exercise of the related warrants, or issuable in payment of interest or
make-whole payments under the 2008 Notes, have, and we expect that any future sales based on such conversions, exercises or issuances will continue to, adversely affect prevailing market prices of our common stock. In addition, the
existence of the 2007 Notes and 2008 Notes may encourage short selling by market participants because the conversion of the 2007 Notes and 2008 Notes could be used to satisfy short positions, or the anticipated conversion of the 2007 Notes or 2008
Notes into shares of our common stock could depress the price of our common stock.

* The covenants in the 2008 Notes restrict our financial and
operational flexibility.

We are subject to certain covenants under the 2008 Notes that restrict our financial and operational
flexibility. For example, we are restricted from incurring additional



50

##### Table of Contents

indebtedness (other than certain project financing debt, certain unsecured subordinated indebtedness and up to $187 million principal amount of additional
indebtedness. The 2008 Notes also include a version of broad-based weighted average anti-dilution protection, subject to certain exceptions and limitations, and the warrants issued in connection with the 2008 Notes also contain weighted-average
anti-dilution protection. Any future financing by us involving the issuance of equity, or rights to acquire equity, at a price or prices below the prevailing conversion price of the 2008 Notes at the time of such financing would trigger these
provisions in the 2008 Notes and the warrants, causing a further, possibly substantial, reduction in the conversion price for the 2008 Notes or the exercise price of the warrants and additional possible dilution for our shareholders, which would
increase the cost and reduce the benefits to us of any such equity financing. As a result of these covenants, our ability to finance our operations through the incurrence of additional debt or the issuance of additional equity is limited. The 2008
Notes also contain other covenants that restrict our financial and operational flexibility.

*Actions we take under our 2008 Notes, as recently amended,
may violate the terms of our 2008 Notes that were in effect prior to the amendment, and if it is ultimately determined that our recent amendment of our 2008 Notes did not effectively amend the 2008 Notes held by all holders, those actions would
cause a default under our 2008 Notes held by one holder.

One holder of the 2008 Notes has filed a lawsuit against us asserting that
our recent amendment of our 2008 Notes, which became effective on July 6, 2009, failed to amend such noteholders 2008 Note (the Disputed Note). This noteholder did not consent to the recent amendment. We have disputed this
assertion and believe that the recent amendment effectively amended all of the 2008 Notes, including the Disputed Note. If it is ultimately determined that the recent amendment did not amend the Disputed Note, certain actions we take that are
permitted under the terms of the 2008 Notes, as recently amended, may cause a default under the Disputed Note. For example, the 2008 Notes, as recently amended, and the Disputed Note contain different provisions regarding the amount of indebtedness
that we may incur, actions that we may take vis-à-vis the 2007 Notes, our use of cash from any sale of specified assets, and with respect to anti-dilution protection. If a default were to occur under the Disputed Note, we could, among other
negative consequences, be required to redeem the Dispute Note in whole or in part and we may not have sufficient funds to do so, which could have a material adverse effect on our business, results of operations and financial condition. Even if we do
not default under the Disputed Note, but it is ultimately determined that the recent amendment did not amend the Disputed Note, we would be subject to stricter covenants under the Disputed Note than under the 2008 Notes, as recently amended, which
would more significantly restrict our financial and operating flexibility. Furthermore, the Disputed Note contains full ratchet anti-dilution protection, while the 2008 Notes, as amended, contain in most cases a version of broad-based weighted
average anti-dilution protection, subject to certain limitations. If the recent amendment did not effectively amend the Disputed Note, any future financing by us involving the issuance of equity, or rights to acquire equity, at a price or prices
below the prevailing conversion price of the Disputed Note at the time of such financing would cause a full ratchet anti-dilution adjustment, rather than a weighted average anti-dilution adjustment as is contemplated currently, in most cases, under
the 2008 Notes, as recently amended. Any such adjustment would cause a larger reduction in the conversion price for the Disputed Note and additional possible dilution for our shareholders, which would increase the cost and reduce the benefits to us
of any such equity financing.

*Our high level of debt limits our ability to fund general corporate requirements, limits our flexibility in responding
to competitive developments, increases our vulnerability to adverse economic and industry conditions, and may harm our financial condition and results of operations.

The face value of our total consolidated long-term debt as of June 30, 2009, which includes the 2007 Notes, the 2008 Notes and debt under our secured credit facility with a commercial bank, was approximately
$127.1 million, representing approximately 109% of our total capitalization as of such dates.

Our level of indebtedness could have
important adverse consequences on our future operations, including:



| |  |  | making it more difficult for us to meet our payment and other obligations under the 2007 Notes, 2008 Notes and our other outstanding debt;
| | - |  | ------------------------------------------------------------------------------------------------------------------------------------------



| |  |  | reducing the availability of our cash flow to fund working capital, capital expenditures, acquisitions and other general corporate purposes, and limiting our
ability to obtain additional financing for these purposes;
| | - |  | ------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------



| |  |  | resulting in an event of default if we fail to comply with the financial and other restrictive covenants contained in our debt agreements, which could result in all
of our debt becoming immediately due and payable;
| | - |  | ----------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------



| |  |  | limiting our flexibility in planning for, or reacting to, and increasing our vulnerability to, changes in our business, the industries in which we operate and the
general economy; and
| | - |  | ---------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------



| |  |  | placing us at a competitive disadvantage compared to our competitors that have less debt or are less leveraged.
| | - |  | ---------------------------------------------------------------------------------------------------------------

Moreover, if we fail to make any required payments under our debt, or otherwise breach the terms of our debt, all or a substantial portion of our debt
could be subject to acceleration. In such a situation, it is unlikely we would be able to repay the accelerated debt, which would have a material adverse impact on our business, results of operations and financial condition, up to and including
causing us to cease operations.

We are dependent on our collaborative partners, and our failure to successfully manage our existing and future
collaboration relationships could prevent us from developing and commercializing cellulosic ethanol and /or our specialty enzyme products, and achieving or sustaining profitability.

Revenue from our collaborations has decreased both as a proportion of our total revenue and in absolute dollars in recent years. Since we do not
currently possess the resources necessary to independently fund the development and commercialization of cellulosic ethanol, or all of the potential specialty enzyme products that may result from our technologies, we expect to continue to pursue,
and in the near-term derive additional revenue from, strategic alliance and collaboration agreements to develop and commercialize products and technologies that are core to our current market focus. We will have limited or no control over the
resources that any strategic partner or collaborator may devote to our products and technologies. Any of our present or future strategic partners or collaborators may fail to perform their obligations as expected. These strategic partners or
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 strategic partners or collaborators may not develop technologies or products
arising out of our collaborative arrangements or devote sufficient resources to the development, manufacture, marketing, or sale of these technologies and products. If any of these events occur, or we fail to enter into or maintain strategic
alliance or collaboration agreements, we may not be able to commercialize our technologies and products, grow our business, or generate sufficient revenue to support our operations.

Our present or future strategic alliance and collaboration opportunities could be harmed if:



| |  |  | We do not achieve our research and development objectives under our strategic alliance and collaboration agreements;
| | - |  | --------------------------------------------------------------------------------------------------------------------



| |  |  | We are unable to fund our obligations under either of our joint ventures with BP or with any of our other strategic partners or collaborators;
| | - |  | ----------------------------------------------------------------------------------------------------------------------------------------------



| |  |  | We are unable to obtain funding to build commercial cellulosic ethanol plants;
| | - |  | ------------------------------------------------------------------------------



| |  |  | We develop technologies or products and processes or enter into additional strategic alliances or collaborations that conflict with the business objectives of our
strategic partners or collaborators;
| | - |  | -------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------



| |  |  | We disagree with our strategic partners or collaborators as to rights to intellectual property we develop, or their research programs or commercialization
activities;
| | - |  | ----------------------------------------------------------------------------------------------------------------------------------------------------------------------



| |  |  | Our strategic partners or collaborators experience business difficulties which eliminate or impair their ability to effectively perform under our strategic
alliances or collaborations;
| | - |  | ----------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------



| |  |  | We are unable to manage multiple simultaneous strategic alliances or collaborations;
| | - |  | ------------------------------------------------------------------------------------



| |  |  | Our strategic partners or collaborators become competitors of ours or enter into agreements with our competitors;
| | - |  | -----------------------------------------------------------------------------------------------------------------



| |  |  | Our strategic partners or collaborators become less willing to expend their resources on research and development due to general market conditions or other
circumstances beyond our control;
| | - |  | ---------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------



| |  |  | Consolidation in our target markets limits the number of potential strategic partners or collaborators; or
| | - |  | ----------------------------------------------------------------------------------------------------------



| |  |  | We are unable to negotiate additional agreements having terms satisfactory to us.
| | - |  | ---------------------------------------------------------------------------------

We do not expect to receive continued funding under our collaboration with Syngenta, which could negatively impact our business.

Our two-year guaranteed funding period totaling $8 million per year through 2008 under our agreement with Syngenta expired on December 31, 2008. While Syngenta has the option to continue funding joint development
beyond 2008, we do not anticipate that we will continue to receive significant funding under this agreement. If we are unable to generate funding from other sources, this decreased funding may materially adversely affect our business and financial
condition.

We do not anticipate paying cash dividends, and accordingly, stockholders must rely on stock appreciation for any return on their investment
in us.

We anticipate that we will retain our earnings, if any, for future growth and therefore do not anticipate paying cash dividends
in the future. As a result, only appreciation of the price of our common stock will provide a return to stockholders. Investors seeking cash dividends should not invest in our common stock.

We may encounter difficulties managing our growth, which could adversely affect our results of operations.

Our strategy includes entering into and working on simultaneous projects, frequently across multiple industries, in both our specialty enzymes and
biofuels businesses. This strategy places increased demands on our limited human resources and requires us to substantially expand the capabilities of our administrative and operational resources and to attract, train, manage and retain qualified

##### Table of Contents

management, technicians, scientists and other personnel, especially with respect to our vertical integration strategy within biofuels. Our ability to
effectively manage our operations, growth, and various projects requires us to continue to improve our operational, financial and management controls, reporting systems and procedures and to attract and retain sufficient numbers of talented
employees, which we may be unable to do. We may not be able to successfully implement improvements to our management information and control systems in an efficient or timely manner. In addition, we may discover deficiencies in existing systems and
controls.

If we engage in any acquisitions, we will incur a variety of costs, may dilute existing stockholders, and may not be able to successfully
integrate acquired businesses.

If appropriate opportunities become available, we may consider acquiring businesses, assets,
technologies, or products that we believe are a strategic fit with our business. As of June 30, 2009, we have no commitments or agreements with respect to any material acquisitions. If we further pursue such a strategy, we could:



| |  |  | issue additional equity securities which would dilute current stockholders percentage ownership;
| | - |  | -------------------------------------------------------------------------------------------------



| |  |  | incur substantial additional debt; or
| | - |  | -------------------------------------



| |  |  | assume additional liabilities.
| | - |  | ------------------------------

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. In addition,
future acquisitions might negatively impact our business relations with our current and/or prospective collaborative partners and/or customers. Any of these adverse consequences could harm our business.

*Our business is subject to complex corporate governance, public disclosure, and accounting requirements that have increased both our costs and the risk of
noncompliance.

Because our common stock is publicly traded, we are subject to certain rules and regulations of federal, state and
financial market exchange entities charged with the protection of investors and the oversight of companies whose securities are publicly traded. These entities, including the Financial Accounting Standards Board, the Public Company Accounting
Oversight Board, the SEC, and NASDAQ, have implemented requirements, standards and regulations, including expanded disclosures, accelerated reporting requirements and more complex accounting rules, and continue developing additional requirements.
Our efforts to comply with these regulations have resulted in, and are likely to continue resulting in, increased general and administrative expenses and diversion of management time and attention from operating activities to compliance activities.
We may incur additional expenses and commitment of managements time in connection with further evaluations, either of which could materially increase our operating expenses or accordingly increase our net loss.

Because new and modified laws, regulations, and standards are subject to varying interpretations, in many cases due to their lack of specificity, their
application in practice may evolve over time as new guidance is provided by regulatory and governing bodies. This evolution may result in continuing uncertainty regarding financial disclosures and compliance matters and additional costs necessitated
by ongoing revisions to our disclosures and governance practices. This further could lead to possible restatements, due to the complex nature of current and future standards and possible misinterpretation or misapplication of such standards.

If we fail to maintain an effective system of internal controls, we may not be able to accurately report our financial results or prevent fraud and as
a result, investors may be misled and lose confidence in our financial reporting and disclosures, and the price of our common stock may be negatively affected.

The Sarbanes-Oxley Act of 2002 requires that we report annually on the effectiveness of our internal control over financial reporting. A significant deficiency means a deficiency or a combination of
deficiencies, in internal control over financial reporting that is less severe than a material weakness yet important enough to merit attention by those responsible for oversight of our financial reporting. A material weakness is a
deficiency, or a combination of deficiencies in internal control over financial reporting, such that there is a reasonable possibility that a material misstatement of the annual or interim financial statements will not be prevented or detected on a
timely basis.

In the past, we have disclosed material weaknesses with our financial statement close process that we have since remediated.
Although we have made and are continuing to make improvements in our internal controls, if we discover other deficiencies or material weaknesses, it may adversely impact our ability to report accurately and in a timely manner our financial condition
and results of operations in the future, which may cause investors to lose confidence in our financial reporting and may negatively affect the price of our common stock. Moreover, effective internal controls are necessary to produce accurate,
reliable financial reports and to prevent fraud. If we continue to have deficiencies in our internal controls over financial reporting, these deficiencies may negatively impact our business and operations.

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 due to becoming involved in expensive lawsuits or administrative proceedings.

Our success depends in
part on our ability to obtain patents and maintain adequate protection of our other intellectual property for our technologies and products in the United States and other countries. In addition, unauthorized parties may attempt to copy or otherwise
obtain and use our products or technology. Monitoring and preventing unauthorized use of our intellectual property is difficult and expensive, and we cannot be certain that the steps we have taken will prevent unauthorized use of our technology,
particularly in foreign countries where the laws may not protect our proprietary rights as fully as in the United States. If competitors are able to use our technology, our ability to compete effectively could be harmed. Although 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, as well as anticipated production capabilities and processes, 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 great harm to our business.

Our commercial success depends in part on not infringing patents and proprietary rights of third parties,
and not breaching any licenses or other agreements that we have entered into with regard to our technologies, products, and business. The patent positions of companies whose businesses are based on biotechnology, including our patent position,
involve complex legal and factual questions and, therefore, enforceability cannot be predicted with certainty. We intend to apply for patents relating to our technologies, processes and products as we deem appropriate. Patents, if issued, may be
challenged, invalidated, or circumvented. We cannot be sure that patents have not been issued that could block our ability to obtain patents or to operate as we would like. Others may develop similar technologies or duplicate technologies developed
by us. There may be patents in some countries that, if valid, may block our ability to commercialize products in these countries if we are unsuccessful in circumventing or acquiring the rights to these patents. There also may be claims in published
patent applications in some countries that, if granted and valid, may also block our ability to commercialize processes or products in these countries if we are unable to circumvent or license them. Our intellectual property rights may be challenged
by others. For example, in February 2007, an interference proceeding was declared in the United States Patent and Trademark Office between a United States patent assigned to us and a pending United States patent application owned by a third
party, with allowable claims directed to our GeneReassembly technology. On February 25, 2008 the Board of Patent Appeals and Interferences ruled in favor of the other party and the claims in our issued patent were cancelled. We are not
currently a party to any litigation with regard to our patent position. However, the biotechnology industry is 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. When and if we become involved in litigation or interference proceedings declared by the United States Patent and Trademark Office, or oppositions or other
intellectual property proceedings outside of the United States, to defend our intellectual property rights or as a result of alleged infringement of the rights of others, we might have to spend significant amounts of money. Any intellectual property
litigation could potentially force us to do one or more of the following:



| |  |  | stop selling, incorporating or using our products that use the challenged intellectual property;
| | - |  | ------------------------------------------------------------------------------------------------



| |  |  | stop production of cellulosic ethanol at our production facilities;
| | - |  | -------------------------------------------------------------------



| |  |  | obtain from the owner of the infringed intellectual property right a license to sell or use the relevant technology, which license may not be available on
reasonable terms, or at all; or
| | - |  | ------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------



| |  |  | redesign those products, facilities or processes that use any allegedly infringing technology, which may result in significant cost or delay to us, or which could
be technically infeasible.
| | - |  | ---------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------

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 we are sued on these patents we would prevail.

Should any third party have filed, or file in the future, patent applications or obtained patents that claim inventions also claimed by us, we may have to participate in an interference proceeding declared by the relevant patent regulatory
agency to determine priority of invention and, thus, the right to a patent for these inventions in the United States. Such a proceeding, like the one described above, could result in substantial cost to us even if the outcome is favorable. Even if
successful, an interference may result in loss of claims. The 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.

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

In order to protect our proprietary technology and processes, we also rely in part on trade secret protection for our confidential and proprietary
information. We have taken measures to protect our trade secrets and proprietary information, but these measures may not be effective. Our policy is to execute confidentiality agreements with our employees and consultants 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, 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.

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 revenue.

Some of our anticipated 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 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 collaborative partners 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, including labeling requirements.
| | - |  | ------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------

The subject of genetically modified organisms has received negative publicity,
which has aroused public debate in the United States and other countries. This adverse publicity could lead to greater regulation and trade restrictions on imports and exports of genetically altered products.

Compliance with regulatory requirements and obtaining required government approvals may be time consuming and costly, and could delay our introduction of products.

All phases, especially the field testing, production, and marketing, of our current and potential products and processes are subject
to significant federal, state, local, and/or foreign governmental regulation. Regulatory agencies may not allow us to produce and/or market our products in a timely manner or under technically or commercially feasible conditions, or at all, which
could harm our business.

In the United States, specialty enzyme products for our target markets are regulated based on their use, by
either the FDA, the EPA, or, in the case of plants and animals, the USDA. The FDA regulates drugs, food, and feed, as well as food additives, feed additives, and substances generally recognized as safe that are used in the processing of food or
feed. While substantially all of our current specialty enzyme projects to date have focused on non-human applications and specialty enzyme products outside of the FDAs review, in the future we may pursue collaborations for further research and
development of drug products for humans that would require FDA approval before they could be marketed in the United States. In addition, any drug product candidates must also be approved by the regulatory agencies of foreign governments before any
product can be sold in those countries. Under current FDA policy, our products, or products of our collaborative partners incorporating our technologies or inventions, to the extent that they come within the FDAs jurisdiction, may be subject
to lengthy FDA reviews and unfavorable FDA determinations if they raise safety questions which cannot be satisfactorily answered, if results from pre-clinical or clinical trials do not meet regulatory requirements or if they are deemed to be food
additives whose safety cannot be demonstrated. An unfavorable FDA ruling could be difficult to resolve and could prevent a product from being commercialized. Even after investing significant time and expenditures, our collaborators may not obtain
regulatory approval for any drug products that incorporate our technologies or inventions. Our collaborators have not submitted an investigational new drug application for any product candidate that incorporates our technologies or inventions, and
no drug product candidate developed with our technologies has been approved for commercialization in the United States or elsewhere. The EPA regulates biologically derived chemical substances not within the FDAs jurisdiction. An unfavorable
EPA ruling could delay commercialization or require modification of the production process resulting in higher manufacturing costs, thereby making the product uneconomical. In addition, the USDA may prohibit genetically engineered plants from being
grown and transported except under an exemption, or under controls so burdensome that commercialization becomes impracticable. Our future products may not be exempted by the USDA.

In order to achieve and maintain market acceptance, our biofuels business will need to meet a significant number of environmental and other regulations
and standards established by various federal, state and local regulatory agencies. As these regulations and standards evolve, and if new regulations or standards are implemented, we may be required to modify our proposed facilities and processes or
develop and support new facilities or processes and this will increase our costs. Any failure to comply, or delays in compliance, with the various existing and evolving industry regulations and standards could prevent or delay our production of
ethanol and the provision of related services including plant operation and engineering services in support of anticipated licenses of our technology, which could harm our biofuels business. Market uncertainty regarding future policies may also
affect our ability to develop new ethanol production facilities or license our technologies to third parties. Any inability to address these requirements and any regulatory changes could have a material adverse effect on our biofuels business,
financial condition and operating results.

Our results of operations may be adversely affected by environmental, health and safety laws, regulations and
liabilities.

We are subject to various federal, state and local environmental laws and regulations, including those relating to the
discharge of materials into the air, water and ground, the generation, storage, handling, use, transportation and disposal of hazardous materials, and the health and safety of our employees. In addition, some of these laws and regulations require
our contemplated facilities to operate under permits that are subject to renewal or modification. These laws, regulations and permits can often require expensive pollution control equipment or operational changes to limit actual or potential impacts
to the environment. A violation of these laws and regulations or permit conditions can result in substantial fines, natural resource damages, criminal sanctions, permit revocations and/or facility shutdowns.

Furthermore, as we operate our business, we may become liable for the investigation and cleanup of environmental contamination at each of the properties
that we own or operate and at off-site locations where we may arrange for the disposal of hazardous substances. If these substances have been or are disposed of or released at sites that undergo investigation and/or remediation by regulatory
agencies, we may be responsible under the Comprehensive Environmental Response, Compensation and Liability Act, or other environmental laws for all or part of the costs of investigation and/or remediation, and for damages to natural resources. We
may also be subject to related claims by private parties alleging property damage and personal injury due to exposure to hazardous or other materials at or from those properties. Some of these matters may require expending significant amounts for
investigation, cleanup, or other costs.

In addition, new laws, new interpretations of existing laws, increased governmental enforcement of
environmental laws, or other developments could require us to make additional significant expenditures. Continued government and public emphasis on environmental issues can be expected to result in increased future investments for environmental
controls at ethanol production facilities. Present and future environmental laws and regulations, and interpretations thereof, applicable to ethanol operations, more vigorous enforcement policies and discovery of currently unknown conditions may
require substantial expenditures that could have a material adverse effect on our results of operations and financial position.

We use hazardous
materials in our business. Any claims relating to improper handling, storage, or disposal of these materials could be time consuming and costly and could adversely affect our business and results of operations.

Our research and development processes involve the controlled use of hazardous materials, including chemical, radioactive, and biological materials. Our
operations also produce hazardous waste products. We cannot eliminate entirely the risk of accidental contamination or discharge and any resultant injury from these materials. Federal, state, and local laws and regulations govern the use,
manufacture, storage, handling, and disposal of 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. In addition,
compliance with applicable environmental laws and regulations may be expensive, and current or future environmental regulations may impair our research, development, or production efforts.

Many 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 biotechnology industry is characterized by rapid technological
change, and the area of biomolecule discovery and optimization from biodiversity is a rapidly evolving field. Our future success will depend on our ability to maintain a competitive position with respect to technological advances. Technological
development by others may result in our products and technologies becoming obsolete.

We face, and will continue to face, intense
competition in our specialty enzymes business. There are a number of companies who compete with us in various steps throughout our technology process. For example, Codexis, Maxygen, Inc., Evotec, and Xencor have alternative evolution technologies.
Integrated Genomics Inc., Myriad Genetics, Inc., and ArQule, Inc. perform screening, sequencing, and/or bioinformatics services. Novozymes A/S, Genencor International Inc., and Dyadic International are involved in development, overexpression,
fermentation, and purification of enzymes. There are also a number of academic institutions involved in various phases of our technology process. Many of these competitors have significantly greater financial and human resources than we do. These
organizations may develop technologies that are superior alternatives to our technologies. Further, our competitors may be more effective at implementing their technologies for modifying DNA to develop commercial products.

##### Table of Contents

The ethanol production and marketing industry is extremely competitive. In addition to cellulosic ethanol
producers using different technology platforms, our competitors are grain ethanol producers as well as other providers of alternative and renewable fuels. Significant competitors in the grain ethanol production and marketing industry include Archer
Daniels Midland Company, Cargill, Inc., VeraSun Energy Corporation, and Aventine Renewable Energy, Inc. Many companies are engaged in research and development activities in the emerging cellulosic ethanol industry, and companies with announced pilot
facility and/or demonstration facility development activities in the cellulosic ethanol space include Abengoa Bioenergy Corp., BlueFire, Genencor, Iogen Corporation, Losonoco, Mascoma, Range Fuels, and Xethanol. Larger industrial companies with
announced cellulosic strategies include Archer Daniels Midland, DONG Energy (Elsam), DuPont/POET (formerly known as Broin), Tate & Lyle, and Novozymes. Cellulosic gasification technologies are being pursued by companies including ClearFuels
and BRI-Infinium. Some or all of these competitors or other competitors, as well as academic, research and government institutions, are developing or may develop technologies for, and are competing or may compete with us in, the production of
ethanol from cellulosic biomass or other feedstocks, such as municipal or construction waste, production of cellulosic ethanol or other fuels employing different steps within the production process, such as acid hydrolysis and/or gasification,
and/or the production of other alternative fuels or biofuels, such as biobutanol. Some of our competitors have substantially greater production, financial, research and development, personnel and marketing resources than we do. 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 lack of resources relative to many of our significant
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 prevent us from achieving any market share, sales and/or profitability, and
adversely affect our results of operations and financial position.

Our ability to compete successfully 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. Current competitors or other companies may develop technologies and products that
are more effective than ours. 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. The existing approaches of our competitors
or new approaches or technology developed by our competitors may be more effective than those developed by us.

If we lose key personnel or are unable
to attract and retain additional personnel, it could delay our product development programs, harm our research and development efforts, and we may be unable to pursue collaborations or develop our own products.

The loss of any key members of our senior management, or business development or scientific staff, or failure to attract or retain other key management,
business development or scientific employees, could prevent us from developing and commercializing biofuels and cellulosic ethanol and other new products 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 San Diego and New England areas, or due
to competition for, or availability of, personnel with the qualifications or experience necessary for our biofuels business, particularly in the Jennings, Louisiana area. If we are not able to attract and retain the necessary personnel to accomplish
our business objectives, we may experience constraints that will adversely affect our ability to meet the demands of our collaborative partners 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, including molecular biologists, biochemists, 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.

Several members of our senior management team are also new and have not worked together for a significant length of time and they
may not be able to work together effectively to develop and implement our business strategies and achieve our business objectives. Management will need to devote significant attention and resources to preserve and strengthen relationships with
employees, customers and others. If our management team is unable to develop successful business strategies, achieve our business objectives, or maintain positive relationships with employees, customers, suppliers or other key constituencies,
including our strategic collaborators and partners, our ability to grow our business and successfully meet operational challenges could be impaired.

Our planned activities will require additional expertise in specific industries and areas applicable to the products and processes developed through our technologies or acquired through strategic or other
transactions, especially in our biofuels business. These activities will require the addition of new personnel, including management, and the development of additional expertise by existing management personnel. The inability to acquire these
services or to develop this expertise could impair the growth, if any, of our business.

We may be sued for product liability.

We may be held liable if any product or process we develop, or any product which is made or process which is performed with the use of any of our
technologies, causes injury or is found otherwise unsuitable during product testing, manufacturing, marketing, or sale. We currently have limited product liability insurance covering claims up to $10 million that may not fully cover our potential
liabilities. In addition, if we attempt to obtain additional product liability insurance coverage, this additional insurance may be prohibitively expensive, or may not fully cover our potential liabilities. Inability to obtain sufficient insurance
coverage at an acceptable cost or otherwise to protect against potential product liability claims could prevent or inhibit the commercialization of products or processes developed by us or our collaborative partners. If we are sued for any injury
caused by our products, our liability could exceed our total assets.

Risks Specific to Our Vertically-Integrated Biofuels Business

We may not be successful in the development of individual steps in, or an integrated process for, the production of ethanol from cellulosic
biomass at commercial scale in a timely or economic manner or at all.

The production of ethanol from cellulosic biomass requires
multiple integrated steps, including:



| |  |  | obtaining the cellulosic raw material;
| | - |  | --------------------------------------



| |  |  | pretreatment of the biomass to make its constituent fibers accessible to enzymes;
| | - |  | ---------------------------------------------------------------------------------



| |  |  | treatment with enzymes to produce fermentable sugars;
| | - |  | -----------------------------------------------------



| |  |  | fermentation by organisms to produce ethanol from the fermentable sugars;
| | - |  | -------------------------------------------------------------------------



| |  |  | distillation of the ethanol to concentrate and separation of it from other materials;
| | - |  | -------------------------------------------------------------------------------------



| |  |  | purification of the ethanol; and
| | - |  | --------------------------------



| |  |  | storage and distribution of the ethanol.
| | - |  | ----------------------------------------

We are currently focused on the pilot-scale research and development of such processes in our pilot facility in Jennings, Louisiana, as well as the optimization of our demonstration-scale facility located at the same site that is intended
to demonstrate the economics of cellulosic ethanol production using our proprietary processes. We have limited experience with sourcing cellulosic feedstocks and distilling ethanol produced from biomass, and we have no experience storing and/or
distributing significant volumes of ethanol produced from biomass sources. To date, we have focused the majority of our research and development efforts on producing ethanol from corn stover, sugarcane bagasse, and wood. The technological and
logistical challenges associated with each one of these processes are extraordinary, and we may not be able to resolve such difficulties in a timely or cost effective fashion, or at all. Even if we are successful in developing an
economical commercial-scale process for converting a particular cellulosic biomass to cellulosic ethanol, we may not be able to adapt such process to other biomass raw materials.

While we have a pilot-scale cellulosic ethanol facility and have commissioned our demonstration-scale cellulosic ethanol facility to demonstrate the
economics of cellulosic ethanol production using our proprietary processes, we have yet to complete the optimization of our demonstration-scale facility, nor have we begun construction of a large-scale commercial cellulosic ethanol
facility. While we have estimated the construction and operating costs for our initial large-scale commercial cellulosic ethanol facilities, these assumptions may prove to be incorrect. Accordingly, we cannot be sure that we can
manufacture cellulosic ethanol in an economical manner at large scale. If we fail to commence large-scale production in a timely manner or to develop large-scale manufacturing capacity and experience, or fail to manufacture cellulosic ethanol
economically on a commercial scale or in commercial volumes, our commercialization of cellulosic ethanol and our business, financial condition, and results of operations will be materially adversely affected.

We may not be able to implement our planned expansion strategy to build, own and operate commercial-scale cellulosic ethanol facilities, including as a result of our
failure to successfully manage our growth, which would prevent us from achieving our goals.

Our strategy currently includes the
continued development of our pilot-scale facility for process development, optimization of our demonstration-scale plant to validate the economics of our processes at commercial-scale volumes of cellulosic ethanol production, and development and
construction of commercial scale plants for the production of large quantities of ethanol for commercial distribution and sale. We plan to grow our business by investing in new facilities and/or acquiring existing facilities, either independently or
with potential development partners, as well as pursuing other business opportunities such as the production of other renewable fuels to the extent we deem those opportunities advisable. We believe that there is increasing competition for suitable
production sites. We may not find suitable sites for construction of new facilities, suitable acquisition candidates or other suitable expansion opportunities.

##### Table of Contents

We must also obtain numerous regulatory approvals and permits in order to construct and operate
facilities. These requirements may not be satisfied in a timely manner or at all. Federal and state governmental requirements may substantially increase our costs, which could have a material adverse effect on our results of operations and financial
position. Our expansion plans may also result in other unanticipated adverse consequences, such as the diversion of managements attention from our existing operations and products.

Rapid growth, resulting from our operation or other involvement with cellulosic ethanol facilities or otherwise, may impose a significant burden on our
administrative and operational resources. Our ability to effectively manage our growth will require us to substantially expand the capabilities of our administrative and operational resources and to attract, train, manage and retain qualified
management, technicians and other personnel. We may be unable to do so.

We may not find additional appropriate sites for new facilities,
or development partners with whom we can implement our growth strategy, and we may not be able to finance, construct, develop or operate these new facilities successfully. We also may be unable to find suitable acquisition candidates. Accordingly,
we may fail to implement our planned expansion strategy, including as a result of our failure to successfully manage our growth, and as a result, we may fail to achieve our goals.

We have experienced, and may continue to experience, significant delays or cost overruns related to our cellulosic ethanol plant projects.

We have experienced cost overruns for our demonstration-scale facility through the commissioning phase. We may continue to experience significant delays
or cost overruns during the optimization phase as a result of a variety of factors, such as shortages of workers or materials, transportation constraints, adverse weather, unforeseen design flaws, construction defects, or labor issues, any of which
could prevent us from commencing or optimizing operations as expected at our facilities.

Our construction costs may also increase to
levels that would make a new facility too expensive to complete or, for demonstration and commercial-scale plants, unprofitable to operate. Contractors, engineering firms, construction firms and equipment suppliers may lack the expertise in
cellulosic ethanol, which may result in delays or cost overruns. Contractors, engineering firms, construction firms and equipment suppliers also receive requests and orders from other clients, including other ethanol companies and, therefore, we may
not be able to secure their services or products on a timely basis or on acceptable financial terms.

If we are unable to successfully commercialize our
technology, our business may fail to generate sufficient revenue, if any, which would adversely affect our operating results.

We
expect to derive a significant portion of our revenue from the commercialization of our proprietary technology for producing fuel-grade cellulosic ethanol by developing, either alone or with partners, cellulosic ethanol production plants and by
licensing our proprietary technology. In order to develop a viable cellulosic ethanol business, we will need to:



| |  |  | successfully complete the optimization of our demonstration facility;
| | - |  | ---------------------------------------------------------------------



| |  |  | successfully design, finance and construct commercial-scale cellulosic ethanol facilities; and
| | - |  | ----------------------------------------------------------------------------------------------



| |  |  | prove that we can operate commercial-scale ethanol facilities at costs that are competitive with grain-based ethanol facilities, other cellulosic ethanol
technologies that may be developed and other alternative fuel technologies that may be developed.
| | - |  | -----------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------

Currently, there are
no commercial-scale cellulosic ethanol production plants in operation in the United States, and we have no previous experience developing, constructing or operating commercial-scale cellulosic ethanol production plants. We are in the optimization
phase of our first demonstration-scale cellulosic ethanol facility. There can be no assurance that we will be able to develop and operate cellulosic ethanol production plants on a commercial scale, that we will be able to successfully license our
technology to third parties, or that any cellulosic ethanol facilities developed by us or our licensees will be profitable.

We are dependent on BP
under our joint ventures in cellulosic ethanol.

We have a strategic partnership with BP to accelerate the development and
commercialization of cellulosic ethanol technology. The first phase of our partnership combines a broad technology platform and operational capabilities in an effort to advance the development of a portfolio of low-cost, environmentally-sound
cellulosic ethanol production facilities in the United States, and potentially throughout the world. The second phase of our partnership is focused on the commercial deployment of our technologies into a commercial-scale cellulosic ethanol
production facility. We are dependent upon BPs financial and technical contributions under both of these joint ventures in order to realize the benefits of the strategic partnership with BP. If BP were not to engage actively in efforts to
perform under our joint ventures or were to pursue alternative efforts in cellulosic ethanol, the joint ventures may not be successful and our business could be harmed. If BP were to discontinue its participation in either of these joint ventures,
we would need to continue the efforts on our own or identify and enter into arrangements with one or more other partners. If we were to have to fund all of the technology development efforts, we would need to raise additional funds to do so, which
would be difficult in the current financing environment. Alternatively, it may be difficult for us to find a different partner that is a good strategic fit and to enter into a new strategic relationship on terms that are favorable to us. If we could
not find an alternative way to pursue our development and commercialization efforts in cellulosic ethanol, our business would be adversely affected.

##### Table of Contents

Our failure to successfully develop our cellulosic ethanol processes and technology would adversely affect our ability
to achieve the benefits under our strategic partnership with BP, and could prevent us from successfully developing and commercializing cellulosic ethanol and achieving or sustaining profitability.

A substantial part of our efforts in our biofuels business over the near term will be focused upon the joint development program with BP. We have agreed
with BP that for a limited period, we will not use our existing technology in any other technology development program in the field of conversion of biomass to fermentable sugars for the production, or the use in production, of ethanol, with limited
exceptions. The limited period may be extended if our joint development program with BP is extended. We are responsible for performance of substantially all of the activities under the joint development program. If we are not successful in achieving
the objectives of the joint development program, BP may terminate the joint development program, and we will no longer be entitled to receive any payments from BP for performance of the joint development program, which would have a material adverse
impact on our business, financial condition, and results of operations. The technology in the defined field that we develop in the course of the joint development program will be owned by Galaxy, a special purpose entity which is equally owned by BP
and us. We will only have access to the technology owned by Galaxy through any license that Galaxy grants to us. In addition, the license to our existing technology that we granted to Galaxy in the defined field will continue in effect on a
non-exclusive basis even if the joint development program terminates, unless the termination is caused by BPs failure to make payments to us when due. If BP terminates the joint development program, we may not be successful in entering into an
agreement with another strategic partner or otherwise economically exploiting our technology in the defined field, and the continuing rights of Galaxy to exploit our existing technology and technology developed during the joint development program
may adversely affect our ability to do so.

If we are unable to perform our obligations under our joint development program with BP, including funding
our portion of its costs, we may lose certain voting rights in the management of Galaxy, the special purpose entity formed to exploit the technology developed through our relationship with BP, and the anticipated economic benefits resulting from the
joint development program may be delayed or may not occur.

We are co-funding our joint development program with BP and have an equal
vote with BP in decisions regarding the management of Galaxy, including decisions regarding future funding, the commercial use of the technology package that we anticipate will result from the joint development program and the timing of monetary
distributions to the owners of Galaxy. However, if we are unable to fund our portion of the joint development program costs, or are unable to fulfill certain of our other obligations under the joint development program, we may lose our ability to
participate in certain aspects of the decision-making process, including decisions about how and when funding occurs. If we are unable to fulfill our funding commitments, BP may chose to fund our portion of the joint development program and to
receive its contributions back before we receive any additional distributions from license fees, royalties or other revenue, which could result in the delay of distributions to us or in our receiving no distributions. A delay or failure to receive
distributions could have a material adverse impact on our future revenues and could have a material adverse impact on our business, financial condition and results of operations.

If we do not participate in projects under our commercial joint venture with BP or are unable to fund our portion of projects that we have elected to participate in under the joint venture, our interest in the
joint venture may be bought out by BP or diluted, and the anticipated economic benefits to us of the joint venture may be lost or reduced.

We are participating in commercial development activities with BP under Vercipia Biofuels LLC, a joint venture owned equally by BP and us, which will act as the commercial entity for the deployment of cellulosic ethanol technology being
developed and proven under our joint development program with BP. This joint venture is intended to progress the development of one of the nations first commercial-scale cellulosic ethanol facilities, located in Highlands County, Florida, and
to create future opportunities for commercializing cellulosic ethanol technologies. If we do not continue to participate in the development of the Vercipia project by funding our portion of the costs, or if we do participate but are unable to meet
our funding obligations with respect to the project, BP may chose to buy out our interest in the joint venture or may dilute our interest in the joint venture. Loss or reduction of our interest in Vercipia could have a material adverse impact on our
future revenues and could have a material adverse impact on our business, financial condition and results of operations.

If we are unable to co-develop
commercial plant production projects with BP under our Vercipia joint venture, we may not achieve the anticipated benefits of our relationship with BP.

There are substantial risks involved in the design, development, and construction of commercial-scale cellulosic ethanol production facilities, which is the focus of our Vercipia joint venture with BP, including, but
not limited to, the following risks:



| |  |  | legal and regulatory risk related to land use, permitting, and environmental regulations;
| | - |  | -----------------------------------------------------------------------------------------



| |  |  | cost overruns;
| | - |  | --------------



| |  |  | risk that technology will not scale from a demonstration to commercial facility;
| | - |  | --------------------------------------------------------------------------------



| |  |  | risk that production costs will not be competitive with the price of competing fuels like gasoline or corn-based ethanol;
| | - |  | -------------------------------------------------------------------------------------------------------------------------

| |  |  | inability to obtain necessary financing to fund the commercial project;
| | - |  | -----------------------------------------------------------------------



| |  |  | decrease in support from the government through loss of subsidies, loss of tax credits, or a decrease in federal financial support including the risk that we may
not be granted the loan guarantee from the DOE which BP and we recently applied for; and
| | - |  | ----------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------



| |  |  | introduction of next-generation technologies that are superior to our cellulosic ethanol process technology.
| | - |  | ------------------------------------------------------------------------------------------------------------

Any one of these factors could have a material adverse impact on our and BPs ability to complete our first planned commercial facility, which would
have a material adverse impact on our business, financial condition and results of operations.

We may not realize the economic return expected from our
acquired in-process research and development.

We allocated $42.4 million of the purchase price of Celunol on June 20, 2007 to
acquired in-process research and development projects. Acquired in-process research and development, or IPR&D, represents the valuation of acquired, to-be-completed research projects. Prior to the merger, Celunols ongoing research and
development initiatives primarily involved the development of its patented and proprietary biotechnology to enable production of fuel-grade ethanol from cellulosic biomass materials. As of the merger date, pursuant to authoritative guidance under
SFAS No. 2, Accounting for Research and Development Costs, these projects were not determined to have reached technological feasibility and have no alternative future use. Accordingly, the amounts allocated to those projects
were expensed in our statements of operations in June 2007, the period in which the merger was consummated.

The values of the research
projects, namely, our Generation 1 or Gen 1 technology, were determined by estimating the costs to develop the acquired technology into commercially viable products, estimating the resulting net cash flows from the projects,
and discounting the net cash flows to their present value. These cash flows were estimated by forecasting total revenue expected from these products and then deducting appropriate operating expenses, cash flow adjustments and contributory asset
returns to establish a forecast of net cash flows arising from the acquired in-process technology. These cash flows were substantially reduced to take into account the time value of money and the risks associated with the inherent difficulties and
uncertainties given the projected stage of development of these projects at closing. Due to the nature of the forecast and the risks associated with the projected growth and profitability of the developmental projects, discount rates of 40% were
considered appropriate for valuation of the IPR&D. We believe that these discount rates were commensurate with the projects stage of development and the uncertainties in the economic estimates described above.

Since our IPR&D represents costs for technology that has not yet reached technological feasibility, we have, and will continue to, require
substantial investment in the future development and commercialization of our Gen 1 technology. While we expect to deploy this technology at a commercial scale as early as 2012, we can not assure you that we will ever be successful in
commercializing this technology. If these projects are not successfully developed, our sales and profitability will be adversely affected in future periods.

If we are unable to successfully operate our pilot cellulosic ethanol production facility or to successfully optimize and operate our demonstration-scale cellulosic ethanol production facility, we may be unable to proceed with the
development of cellulosic facilities on a commercial-scale, which would have a material adverse effect on our business.

To date, we
have not operated demonstration-scale cellulosic ethanol facilities or built or operated commercial-scale cellulosic ethanol facilities. The development of a portfolio of ethanol production facilities is dependent on the performance of our pilot
facility, which we continue to upgrade, as well as our demonstration facility, which is now in the optimization phases. The operation of our pilot facility and the optimization of our demonstration facility might be subject to significant
interruption and delay in case of a major accident or damage from severe weather or other natural disasters, or due to supply shortages of necessary materials and services which we, along with other participants in the ethanol industry, have
experienced. For these and other reasons, the operation of our pilot facility and the optimization and operation of our demonstration facility may be subject to significant cost overruns from our budgeted amounts. If we are unable to fund these
expenditures, our progress at the pilot facility and demonstration facility could be significantly delayed or curtailed until such financing is available. In addition, our demonstration facility, once operational, may not produce ethanol in
sufficient quantities or the operating costs for the facility may be significantly higher than we have expected. If we are unable to produce ethanol in the demonstration facility at competitive variable and/or total costs, we may be unable to
proceed with the development of commercial-scale facilities.

##### Table of Contents

In order to successfully develop commercial-scale facilities, we will need to address siting, construction and other
issues, and if we fail to successfully overcome these issues we will not be able to commercialize our technology.

Even if we can
demonstrate that our technology can be deployed on a commercial-scale to produce cellulosic ethanol on a cost-competitive basis, in order to be successful we must develop a number of commercial-scale projects. In order to successfully develop
commercial-scale projects, we must overcome a number of risks and uncertainties including the following:



| |  |  | Sites. In order to develop commercial facilities, we will need to identify and obtain rights to appropriate sites. In evaluating and obtaining sites, we
will need to address a number of issues, including the proximity to potential feedstocks and proximity to transportation infrastructure and end-user markets. Competition for suitable cellulosic ethanol production sites may increase as the market
evolves. We may not find suitable additional sites for the construction of new facilities.
| | - |  | ---------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------



| |  |  | Joint Venture Partners. In addition to identifying sites for projects we develop on our own and with BP, we may seek to develop commercial facilities
through other joint venture partners. We may not find suitable joint venture partners for construction of new facilities. As the market for cellulosic ethanol projects evolves, competition may increase for potential joint venture partners with
favorable sites.
| | - |  | --------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------



| |  |  | Supply of Cellulosic Feedstock. Operation of commercial facilities requires a continuous long-term supply of feedstocks that are generally located in
geographic proximity to the facility. We may not be successful in obtaining long-term supply agreements, or our supply of feedstocks could be disrupted by weather, climate, natural disasters, or other factors. In addition, prices and competition for
feedstocks could increase, adversely effecting our ability to operate economically or at all.
| | - |  | -------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------



| |  |  | Off-Take Arrangements. In order to successfully develop a commercial-scale facility, we will need to enter into off-take arrangements for the sale of
ethanol to be produced at that facility. If we are unable to enter into appropriate off-take arrangements, we may be unable to obtain project financing for the particular facility.
| | - |  | ------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------



| |  |  | Construction. We will need to identify and retain a significant number of contractors, engineering firms, construction firms and equipment suppliers on
satisfactory terms in order to be able to develop and construct multiple commercial-scale cellulosic ethanol facilities. These vendors also receive requests and orders from other companies in the ethanol and other industries and, therefore, we may
not be able to secure their services or products on a timely basis or on acceptable financial terms. If we are unable to enter into construction and supply contracts on satisfactory terms, we will not be able to obtain financing for our commercial
scale projects. In addition, our construction costs may also increase to levels that would make a new facility too expensive to develop or unprofitable to operate.
| | - |  | -------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------



| |  |  | Operating Risks. If we are able to build commercial-scale ethanol facilities, our operation of these facilities may be subject to labor disruptions and
unscheduled downtime, or other operational hazards inherent in the ethanol industry, such as equipment failures, fires, explosions, abnormal pressures, blowouts, pipeline ruptures, transportation accidents and natural disasters. Some of these
operational hazards may cause personal injury or loss of life, severe damage to or destruction of property and equipment or environmental damage, and may result in suspension of operations and the imposition of civil or criminal penalties. Our
insurance may not be adequate to fully cover the potential operational hazards described above. Any delay in development or interruption due to these potential operational risks could result in substantial losses and material adverse effects on our
results of operations.
| | - |  | ----------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------

We will rely heavily on future strategic partners to support our biofuels business.

An important component of our current business plan is to enter into strategic partnerships:



| |  |  | to provide capital, equipment and facilities, including significant capital for the construction of cellulosic ethanol research and production facilities;
| | - |  | ----------------------------------------------------------------------------------------------------------------------------------------------------------



| |  |  | to provide expertise in performing certain process development, production and logistical activities;
| | - |  | -----------------------------------------------------------------------------------------------------



| |  |  | to provide funding for research and development programs, process development programs and commercialization activities;
| | - |  | ------------------------------------------------------------------------------------------------------------------------



| |  |  | to provide access to cellulosic feedstocks; and
| | - |  | -----------------------------------------------



| |  |  | to support or provide sales, marketing and distribution services.
| | - |  | -----------------------------------------------------------------

These arrangements with collaborative partners are, and will continue to be, critical to our success in implementing our vertical integration biofuels strategy and manufacturing and selling cellulosic ethanol
profitably. We cannot guarantee that any collaborative relationship(s) will be entered into, or if entered into, will continue or be successful. Our collaborative partners could experience business difficulties which eliminate or impair their
ability to effectively perform under our arrangements with them. Failure to make or maintain these arrangements or a delay or failure in a collaborative partners performance under any such arrangements would materially adversely affect our
business and financial condition.

##### Table of Contents

We cannot control our collaborative partners performance or the resources they devote to our
programs. We may not always agree with our partners nor will we have control of our partners activities. The performance of our programs may be adversely affected and programs may be delayed or terminated or we may have to use funds,
personnel, equipment, facilities and other resources that we have not budgeted to undertake certain activities on our own as a result of these disagreements. Performance issues, program delays or termination or unbudgeted use of our resources may
materially adversely affect our business and financial condition.

Disputes may arise between us and a collaborative partner and may
involve the issue of which of us owns the technology and other intellectual property that is developed during a collaboration or other issues arising out of the collaborative agreements. Such a dispute could delay the program on which we are working
or could prevent us from obtaining the right to commercially exploit such developments. It could also result in expensive arbitration or litigation, which may not be resolved in our favor. Our collaborative partners could merge with or be acquired
by another company or experience financial or other setbacks unrelated to our collaboration that could, nevertheless, adversely affect us.

In order to
gain broad acceptance of our technology, we may need to enter into licensing arrangements with third parties. If we fail to successfully identify and enter into licenses with qualified third parties or to successfully manage existing and future
licensing relationships, we may not be able to successfully commercialize our technology.

We currently have a technology transfer
agreement in place with Marubeni Corporation and Tsukishima Kikai Co., Ltd. We also expect that a significant portion of our future revenue could be derived from licensing agreements that we or our Galaxy joint venture with BP will enter into in the
future. If we fail to enter into and maintain license agreements, we may not be able to gain broad acceptance for our technology, grow our business or generate sufficient revenues to support our operations. Our future license opportunities could be
harmed if:



| |  |  | we do not successfully operate our pilot facility or successfully optimize and operate our demonstration facility;
| | - |  | ------------------------------------------------------------------------------------------------------------------



| |  |  | we are unable to successfully develop commercial-scale facilities;
| | - |  | ------------------------------------------------------------------



| |  |  | we develop processes or enter into licenses that conflict with the business objectives of our existing licensees;
| | - |  | -----------------------------------------------------------------------------------------------------------------



| |  |  | we disagree with our licensees as to rights to intellectual property we develop or our licensees research programs or commercialization activities;
| | - |  | ----------------------------------------------------------------------------------------------------------------------------------------------------



| |  |  | we are unable to manage multiple licensee relationships;
| | - |  | --------------------------------------------------------



| |  |  | our licensees become our competitors or enter into agreements with our competitors;
| | - |  | -----------------------------------------------------------------------------------



| |  |  | our licensees become less willing to expend their resources on research or development due to general market conditions or other circumstances beyond our control;
or
| | - |  | ---------------------------------------------------------------------------------------------------------------------------------------------------------------------



| |  |  | consolidation in our target markets limits the number of potential strategic licensees or we are unable to negotiate additional license agreements having terms
satisfactory to us.
| | - |  | -----------------------------------------------------------------------------------------------------------------------------------------------------------------------------------

We may not be able to develop manufacturing capacity sufficient to meet demand in an economical manner or at all.

If demand for cellulosic ethanol increases beyond the scope of our production facilities, we may incur significant expenses in the
expansion and/or construction of production facilities and increases in personnel in order to increase production capacity. To finance the expansion of a commercial-scale production facility is complex and expensive. We cannot assure you that we
will have the necessary funds to finance the development of production facilities, or that we will be able to develop this infrastructure in a timely or economical manner, or at all.

The feedstocks, raw materials and energy necessary to produce ethanol may be unavailable or may increase in price, adversely affecting our sales and profitability.

We intend to use various sources of cellulosic biomass, such as sugarcane bagasse, dedicated energy crops, agricultural residues (which may include corn
stover), sorghum, switchgrass and wood, to make cellulosic ethanol. However, rising prices for any or all of these feedstocks would produce lower profit margins and, therefore, represent unfavorable market conditions. This is especially true since
market conditions generally would not allow us to pass along increased costs to customers, because the price of ethanol is primarily determined by other factors, such as the price of oil and gasoline. Additionally, once we elect to use a particular
feedstock in the ethanol production process, it may be technically or economically impractical to change to a different feedstock. At certain levels, feedstock prices may make ethanol uneconomical to use in markets where the use of fuel oxygenates
is not mandated.

##### Table of Contents

Weather conditions and other factors affecting crop yields, farmer planting decisions, and general
economic, market and regulatory factors may influence the availability, transportation costs and price of biomass feedstocks used in our pilot facility and to be used in our demonstration- and commercial-scale production facilities. There can be no
guarantee that feedstock costs to us may not increase over time. Government policies and subsidies with respect to agriculture and international trade, and global and local demand and supply, also impact the price and transportation costs of
agricultural products. The significance and relative effects of these factors on the potential cost of feedstocks are difficult to predict. Any increase in the cost of feedstocks will result in increased costs, and negative effects on our operating
results. Other inputs to our cellulosic-ethanol production process will also be subject to price variation. These include chemicals, nutrients, enzymes, acid and lime, among others. Increases in the costs of these materials, or our failure to
achieve reductions in the use of such materials, could increase our operating costs and have negative effects on our operating results. The gross margin of our anticipated ethanol production business depends principally on the spread between the
price for ethanol and our production costs. Any increase in production costs or decrease in the demand or price of ethanol will negatively affect our business.

The production of ethanol also requires a significant amount of other raw materials and energy, primarily water, electricity and natural gas. We plan to utilize the lignin remaining after the pretreatment of
cellulosic biomass as a source of energy to power our cellulosic ethanol production facilities, however we may not be successful in using lignin as a source of energy and, if so, we may have to supplement our energy use with other sources, including
electricity and natural gas. The prices of electricity and supplemental fuels such as natural gas have fluctuated significantly in the past and may fluctuate significantly in the future. Local water, electricity and gas utilities may not be able to
reliably supply the water, electricity and supplemental fuels that our facilities will need or may not be able to supply such resources on acceptable terms. In addition, if there is an interruption in the supply of water or energy for any reason, we
may be required to halt ethanol production.

The high concentration of our efforts towards developing processes for the production of cellulosic ethanol
could increase our losses, especially if demand for ethanol declines.

If we are successful in producing and marketing cellulosic
ethanol, our revenue will be derived primarily from sales of ethanol. Ethanol competes with several other existing products and other alternative products could also be developed for use as fuel additives. An industry shift away from ethanol or the
emergence of new competing products may reduce the demand for ethanol. A downturn in the demand for ethanol would significantly and adversely affect any sales and/or profitability.

The market price of ethanol is volatile and subject to significant fluctuations, which may cause our profitability from the production of cellulosic ethanol to fluctuate significantly.

The market price of ethanol is dependent upon many factors, including the price of gasoline, which is in turn dependent upon the price of petroleum.
Petroleum prices are highly volatile and difficult to forecast due to frequent changes in global politics and the world economy. The distribution of petroleum throughout the world is affected by incidents in unstable political environments, such as
Iraq, Iran, Kuwait, Saudi Arabia, Nigeria, Venezuela, the former U.S.S.R. and other countries and regions. The industrialized world depends critically upon oil from these areas, and any disruption or other reduction in oil supply can cause
significant fluctuations in the prices of oil and gasoline. We cannot predict the future price of oil or gasoline and may establish unprofitable prices for the sale of ethanol due to significant fluctuations in market prices. In recent years, the
prices of gasoline, petroleum and ethanol have all reached historically high levels. If the prices of gasoline and petroleum decline, we believe that the demand for and price of ethanol may be adversely affected. Fluctuations in the market price of
ethanol may cause our revenue and profitability to fluctuate significantly from quarter-to-quarter and year-to-year.

We believe that the
production of ethanol is expanding rapidly. There are a number of new plants under construction and planned for construction throughout the United States. We expect existing ethanol plants to expand by increasing production capacity and actual
production. Increases in the demand for ethanol may not be commensurate with increasing supplies of ethanol. Thus, increased production of ethanol may lead to lower ethanol prices. Also, the increased production of ethanol could result in increased
demand for feedstocks for the production of ethanol. This could result in higher prices for feedstocks and cause higher ethanol production costs and, in the event that we are unable to pass increases in the price of feedstocks on to our customers,
will result in lower profits. We cannot predict the future price of ethanol or feedstocks. Any material decline in the price of ethanol, or any material increase in the price of feedstocks, will adversely affect any sales and/or profitability.

If ethanol demand decreases, does not increase, or does not increase as much as supply, there may be excess capacity
in our industry which would likely cause a decline in ethanol prices, adversely impacting our results of operations, cash flows and financial condition.

Domestic fuel ethanol production has increased steadily from 1.5 billion gallons per year in 1999 to 9.2 billion gallons per year in 2008, according to the Renewable Fuels Association. In addition, there is a
significant amount of capacity being added to the fuel ethanol industry, including capacity that may be added as a result of government programs and/or incentives, and capacity added to address anticipated increases in demand. However, demand for
ethanol may not increase as quickly as expected, or at all. If the ethanol industry has excess capacity, a fall in prices will likely occur which will have an adverse impact on the viability of our vertical integration strategy within biofuels, as
well as our results of operations, cash flows and financial condition if we proceed to market ethanol. Demand for ethanol could be impaired due to a number of factors, including regulatory developments and reduced United States gasoline consumption.
Reduced gasoline consumption could occur as a result of increased gasoline or oil prices. For example, price increases could cause businesses and consumers to reduce driving or acquire vehicles with more favorable gasoline mileage capabilities.

The United States ethanol industry is highly regulated by federal and state legislation and regulation and any changes in such legislation or
regulation could materially adversely affect our results of operations and financial condition.

The elimination or significant
reduction in the Federal Excise Tax Credit could have a material adverse effect on our results of operations.

The production of ethanol
is made significantly more competitive by federal tax incentives. The Volumetric Ethanol Excise Tax Credit, or VEETC, program, which is scheduled to expire on December 31, 2010, allows gasoline distributors that blend ethanol with gasoline to
receive a federal excise tax rate reduction for each blended gallon they sell regardless of the blend rate. The current federal excise tax on gasoline is $0.184 per gallon, and is paid at the terminal by refiners and marketers. If the fuel is
blended with ethanol, the blender may claim a $0.45 tax credit for each gallon of ethanol used in the mixture. In addition, Congress enacted a $1.01/gallon production tax credit (PTC) that is available to cellulosic biofuels producers in
the Farm, Conservation and Energy Act of 2008 (FCEA). This credit, which is inclusive of the VEETC, is set to expire on December 31, 2012. The VEETC may not be renewed prior to its expiration in 2010, or if renewed, it may be renewed on
terms significantly less favorable than current tax incentives. In addition, the blenders credits, as well as other federal and state programs benefiting ethanol (such as tariffs), generally are subject to United States government obligations
under international trade agreements, including those under the World Trade Organization Agreement on Subsidies and Countervailing Measures, and might be the subject of challenges thereunder, in whole or in part. The elimination or significant
reduction in either the VEETC or the PTC could have a material adverse effect on our results of operations.

Waivers of the Renewable
Fuels Standard minimum levels of renewable fuels included in gasoline, or the lapse of the increased weight given for the use of cellulosic ethanol for compliance with the Renewable Fuels Standard, could have a material adverse effect on our results
of operations.

Under the Energy Policy Act of 2005, the Department of Energy, in consultation with the Secretary of Agriculture and the
Secretary of Energy, may waive the Renewable Fuels Standard, or RFS, mandate with respect to one or more states if the administrator determines that implementing the requirements would severely harm the economy or the environment of a state, a
region or the United States, or that there is inadequate supply to meet the requirement. Any waiver of the RFS with respect to one or more states or with respect to a particular year, or the lapse or alteration of the extra weight cellulosic ethanol
is given in complying with the RFS, could adversely affect demand for ethanol and could have a material adverse effect on our results of operations and financial condition.

While the Energy Policy Act of 2005 imposes the RFS, it does not mandate the use of ethanol and eliminates the oxygenate requirement for reformulated
gasoline in the Reformulated Gasoline Program included in the Clean Air Act.

The Reformulated Gasoline, or RFG, programs
oxygenate requirements contained in the Clean Air Act was completely eliminated on May 5, 2006 by the Energy Policy Act of 2005. While the RFA expects that ethanol should account for the largest share of renewable fuels produced and consumed
under the RFS, the RFS is not limited to ethanol and also includes biodiesel and any other liquid fuel produced from biomass or biogas. The elimination of the oxygenate requirement for reformulated gasoline in the RFG program included in the Clean
Air Act may result in a decline in ethanol consumption in favor of other alternative fuels, which in turn could have a material adverse effect on our results of operations and financial condition.

The elimination or alteration of the mandates for ethanol use contained in the Energy Independence and Security Act of 2007 could have a material
adverse effect on our results of operations.

Under the Energy Independence and Security Act of 2007, use of renewable fuels, including
ethanol, in the United States is mandated to increase from 9 billion gallons in 2008 to 36 billion gallons by 2022. The Act also mandates the use of 16 billion gallons per year of cellulosic ethanol by 2022. Elimination or reduction
of these mandated targets could adversely effect demand for ethanol and could have a material adverse effect on our results of operations and financial condition.

Changes in enacted federal, state or local legislation, or the enaction of new legislation, may adversely impact our
business.

Federal, state and local legislators may enact legislation, or modify or amend currently enacted legislation, that could
adversely affect the industries in which we currently operate. For example, several federal laws encourage the development of the ethanol and/or biofuels industry in the United States. If those laws are repealed or are not renewed, it could
adversely impact the ethanol and/or biofuels industries as a whole, which would have an adverse effect on our financial results. In addition, legislation could be enacted that might not negatively impact our industry as a whole, but could negatively
impact that portion of the industry in which we operate or our particular business. For example, in the future we may consider the effect of state or local incentives, such as grants or tax abatements, in formulating our internal projections and
budgets and when choosing where to locate and operate commercial-scale plants for the production of cellulosic ethanol. If those incentives should be repealed or no longer become available, the profitability of any commercial-scale plants which are
reliant on such incentives could be negatively affected, which in turn would negatively affect our operating results.

Certain countries can export
ethanol to the United States duty-free, which may undermine the ethanol production industry in the United States.

Imported ethanol is
generally subject to a $0.54 per gallon tariff and a 2.5% ad valorem tax that was designed to offset the $0.51 per gallon ethanol subsidy available under the federal excise tax incentive program for refineries that blend ethanol in their fuel. There
is a special exemption from the tariff for ethanol imported from certain countries in Central America and the Caribbean islands, which is limited to a total of 7.0% of United States production per year (with additional exemptions for ethanol
produced from feedstock in the Caribbean region over the 7.0% limit). We do not know the extent to which the volume of imports would increase or the effect on United States prices for ethanol if the tariff is not renewed beyond its current
expiration in early 2011. In addition The North America Free Trade Agreement countries, Canada and Mexico, are exempt from duty. Imports from the exempted countries have increased in recent years and are expected to increase further as a result of
new plants under development. In particular, the ethanol industry has expressed concern with respect to a new plant under development by Cargill, Inc., one of the largest ethanol producers in the United States, in El Salvador that would take the
water out of Brazilian ethanol and then ship the dehydrated ethanol from El Salvador to the United States duty-free. Since production costs for ethanol in Brazil are estimated to be significantly less than what they are in the United States, the
import of the Brazilian ethanol duty-free through El Salvador, or the import of ethanol duty-free from any country exempted from the tariff, may negatively impact the demand for domestic ethanol and the price at which we sell our ethanol.

Our competitive position, financial position and results of operations may be adversely affected by technological advances.

Even if we are able to execute our business plan and develop commercial-scale cellulosic ethanol production plants and successfully license our
proprietary technology, the development and implementation of new technologies may result in a significant reduction in the costs of ethanol production by others. For example, any technological advances by others in the efficiency or cost to produce
ethanol from corn or other biomass could have an adverse effect on our competitiveness. We cannot predict when new technologies may become available, the rate of acceptance of new technologies by our competitors or the costs associated with new
technologies. In addition, advances in the development of alternatives to ethanol could significantly reduce demand for or eliminate the need for ethanol. Any advances in technology which require significant capital expenditures to remain
competitive or which reduce demand or prices for ethanol would have a material adverse effect on the results of our operations and financial position.

The termination or loss of our exclusive license from the University of Florida Research Foundation, Inc., would have a material adverse effect on our business.

We have an exclusive worldwide license to use, develop and commercially exploit the ethanol production patent estate of the University of Florida
Research Foundation, Inc., or UFRFI, which consists of several patents and pending patents and other related proprietary ethanol technology, and any extensions and improvements thereof for the production of ethanol, all of which is referred to
herein as the UFRFI technology. The UFRFI license agreement expires on the later of October 2015 or the expiration of the last patent related to the UFRFI licensed technology. Based on the latest to expire of the current granted United States
patents, the UFRFI license agreement will extend into 2022. Pending and future patent applications related to the UFRFI licensed technology, if granted, would extend the expiration date of the UFRFI license agreement beyond 2026. Loss of the rights
to the UFRFI technology licensed to us, for example, due to our inability to comply with the terms and conditions or otherwise of the UFRFI license agreement would have a material adverse effect on our business.

Growth in the sale and distribution of ethanol is dependent on the changes to and expansion of related infrastructure
which may not occur on a timely basis, if at all, and our contemplated operations could be adversely affected by infrastructure disruptions.

Substantial development of infrastructure will be required by persons and entities outside our control for our contemplated licensing and cellulosic ethanol production operations, and the ethanol industry generally, to grow. Areas requiring
expansion include, but are not limited to:



| |  |  | the automobile industrys manufacture of flexible fuel vehicles;
| | - |  | ----------------------------------------------------------------



| |  |  | additional rail capacity affecting distribution of ethanol;
| | - |  | -----------------------------------------------------------



| |  |  | additional storage facilities for ethanol;
| | - |  | ------------------------------------------



| |  |  | increases in truck fleets capable of transporting ethanol within localized markets;
| | - |  | -----------------------------------------------------------------------------------



| |  |  | expansion of refining and blending facilities to handle ethanol; and
| | - |  | --------------------------------------------------------------------



| |  |  | growth in service stations equipped to handle ethanol fuels.
| | - |  | ------------------------------------------------------------

Substantial investments required for these infrastructure changes and expansions may not be made or they may not be made on a timely basis. Any delay or failure in making the changes to or expansion of infrastructure
could hurt the demand for our proprietary technology or the production of cellulosic ethanol, impede our delivery of cellulosic ethanol, impose additional costs on us, or otherwise have a material adverse effect on our results of operations or
financial position. Our contemplated business will be dependent on the continuing availability of infrastructure and any infrastructure disruptions could have a material adverse effect on our business.

New ethanol plants under construction or decreases in the demand for ethanol may result in excess United States production capacity.

A number of our competitors are divisions of substantially larger enterprises and have substantially greater financial resources than we have. Smaller
competitors also pose a threat. Farmer-owned cooperatives and independent firms consisting of groups of individual farmers and investors have been able to compete successfully in the ethanol industry. These smaller competitors operate smaller
facilities which do not affect the local price of corn grown in proximity to the facility as much as larger facilities. In addition, many of these smaller competitors are farmer-owned and often require their farmer-owners to commit to selling them a
certain amount of corn as a requirement of ownership. A significant portion of production capacity in the ethanol industry consists of smaller-sized facilities. In addition, institutional investors and high net worth individuals could heavily invest
in ethanol production facilities and oversupply the demand for ethanol, resulting in lower ethanol price levels that might adversely affect the results of our contemplated cellulosic ethanol production operations and financial position.

Risks Specific to Our Specialty Enzymes Business

*Macroeconomic conditions beyond our control could lead to decreases in demand for our products, reduced profitability or deterioration in the quality of our accounts receivable.

Domestic and international economic, political and social conditions are uncertain due to a variety of factors, including



| |  |  | global, regional and national economic downturns;
| | - |  | -------------------------------------------------



| |  |  | the availability and cost of credit;

Our business depends on our customers demand for our products and services, the general economic
health of current and prospective customers, and their desire or ability to make investments in technology. A deterioration of global, regional or local political, economic or social conditions could affect potential customers in a
way that reduces demand for our products and disrupts our manufacturing and sales plans and efforts. These global, regional or local conditions also could disrupt commerce in ways that could interrupt our supply chain and our ability to get
products to our customers. These conditions may also affect our ability to conduct business as usual. Changes in foreign currency exchange rates may negatively impact reported revenue and expenses. In addition, our sales are typically
made on unsecured credit terms that are generally consistent with the prevailing business practices in the country in which the customer is located. A deterioration of political, economic or social conditions in a given country or region could
reduce or eliminate our ability to collect accounts receivable in that country or region. In any of these events, our results of operations could be materially and adversely affected.

*The financial instability of our customers could adversely affect our business and result in reduced sales, profits and cash flows.

We sell our products to and extend credit to our customers based on an evaluation of each customers financial condition, usually without requiring
collateral. Our Fuelzyme customers are particularly exposed to the challenges facing the corn ethanol industry. While customer credit losses have historically been within our expectations and reserves, we cannot assure you that this will continue.
The financial difficulties of a customer could cause us to curtail business with that customer or the customer to reduce its business with us and cancel orders. Our inability to collect on our trade accounts receivable from any of our major
customers could adversely affect our results of operations and financial condition.

*Our international manufacturing operations are subject to the
risks of doing business abroad, which could affect our ability to manufacture our products in international markets, obtain products from foreign suppliers or control the costs of our products.

We manufacture a majority of our commercial enzyme products through a manufacturing facility in Mexico City owned by Fermic S.A., or Fermic. As a result,
we are subject to the general risks of doing business outside the U.S., particularly Mexico, including, without limitation, work stoppages, transportation delays and interruptions, political instability, expropriation, nationalization, foreign
currency fluctuation, changing economic conditions, the imposition of tariffs, import and export controls and other non-tariff barriers, and changes in local government administration and governmental policies, and to factors such as the short-term
and long-term effects of health risks like the recent outbreak of swine flu. There can be no assurance that these factors will not adversely affect our business, financial condition or results of operations.

If we are unable to access the capacity to manufacture products in sufficient quantity, we may not be able to commercialize our products or generate significant
sales.

We have only limited experience in enzyme manufacturing, and we do not have our own internal capacity to manufacture specialty
enzyme products on a commercial scale. We expect to be dependent to a significant extent on third parties for commercial scale manufacturing of our specialty enzyme products. We have arrangements with third parties that have the required
manufacturing equipment and available capacity to manufacture our commercial enzymes. While we have our own pilot development facility, we continue to depend on third parties for large-scale commercial manufacturing. Additionally, one of our third
party manufacturers is located in a foreign country, and is our sole-source supplier for most of our commercial enzyme products. Any difficulties or interruptions of service with our third party manufacturers or our own pilot manufacturing facility
could disrupt our research and development efforts, delay our commercialization of specialty enzyme products, and harm our relationships with our specialty enzyme strategic partners, collaborators, or customers.

We have experienced inventory losses and decreased manufacturing yields related to our manufacturing processes for Phyzyme and Fuelzyme, which negatively impacted our
product gross margins.

We have in the past experienced inventory losses and decreased manufacturing yields related to contamination
and manufacturing issues for Phyzyme and Fuelzyme. While we believe we have adequately resolved our contamination issues and have recovered a substantial portion of such losses from our third-party manufacturer Fermic, there can be no assurance that
such losses will not occur in the future or that any amount of future losses will be reimbursed by Fermic. If such contamination issues continue in future periods, or we are not able to otherwise improve our manufacturing yields, our results of
operations and financial condition would be adversely affected.

If Danisco or its subsidiary company, Genencor, assumes all or a part of our Phyzyme manufacturing, our gross product
revenues will be adversely impacted and our product gross margins could decline.

Due to capacity constraints at Fermic in 2008, we
were not able to supply adequate quantities of Phyzyme necessary to meet the increased demand from Danisco. As a result, we contracted with Genencor, a subsidiary of Danisco, to serve as a second-source manufacturer for Phyzyme. Pursuant to current
accounting rules, revenue from Phyzyme that is supplied to us by Genencor is recognized in an amount equal to the net profit share received from Danisco, as compared to the full value of the manufacturing costs plus profit share we currently
recognize for Phyzyme we manufacture at Fermic. While this revenue recognition treatment has little or no negative impact on the gross margin we recognize for every sale of Phyzyme, it does have a negative impact on the gross product revenue we
recognize for Phyzyme as the volume of Phyzyme manufactured by Genencor increases.

In addition, our supply agreement with Danisco for
Phyzyme contains provisions which allow Danisco, with six months advance notice, to assume manufacturing rights of Phyzyme. If Danisco were to exercise this right, we may experience significant excess capacity at our third party manufacturing
facility. If we were unable to absorb this excess capacity with other products, our results of operations and financial condition would be adversely effected.

We have only limited experience in independently developing, manufacturing, marketing, selling, and distributing commercial specialty enzyme products.

We currently have only limited resources and capability to develop, manufacture, market, sell, or distribute specialty enzyme products on a commercial scale. We will determine which specialty enzyme products to pursue
independently based on various criteria, including: investment required, estimated time to market, regulatory hurdles, infrastructure requirements, and industry-specific expertise necessary for successful commercialization. At any time, we may
modify our strategy and pursue collaborations for the development and commercialization of some specialty enzyme products that we had intended to pursue independently. We may pursue specialty enzyme products that ultimately require more resources
than we anticipate or which may be technically unsuccessful. In order for us to commercialize more specialty enzyme products directly, we would need to establish or obtain through outsourcing arrangements additional capability to develop,
manufacture, market, sell, and distribute such products. If we are unable to successfully commercialize specialty enzyme products resulting from our internal product development efforts, we will continue to incur losses in our specialty enzymes
business, as well as in our business as a whole. Even if we successfully develop a commercial specialty enzyme product, we may not generate significant sales and achieve profitability in our specialty enzymes business, or in our business as a whole.

We have relied, and will continue to rely, heavily on strategic partners to support our specialty enzymes business.

Historically, we have relied upon a number of collaborations, including those with Syngenta, Danisco, Bunge, Cargill, and BASF, to enhance and support
our development and commercialization efforts for our specialty enzymes. An important component of our business plan is to enter into strategic partnerships:



| |  |  | to provide capital, equipment and facilities, including significant capital to develop and expand our enzyme manufacturing capabilities;
| | - |  | ----------------------------------------------------------------------------------------------------------------------------------------



| |  |  | to provide funding for research and development programs, process development programs and commercialization activities for our specialty enzyme products; and
| | - |  | --------------------------------------------------------------------------------------------------------------------------------------------------------------



| |  |  | to support or provide sales, marketing and distribution services for our specialty enzyme products.
| | - |  | ---------------------------------------------------------------------------------------------------

These arrangements with collaborative partners are, and will continue to be, critical to the success of our specialty enzymes business. We cannot
guarantee that any collaborative relationship(s) will be entered into, or if entered into, will continue or be successful. Our collaborative partners could experience business difficulties which eliminate or impair their ability to effectively
perform under our arrangements with them. Failure to make or maintain these arrangements or a delay or failure in a collaborative partners performance under any such arrangements would materially adversely affect our business and financial
condition.

We cannot control our collaborative partners performance or the resources they devote to our programs. We may not always
agree with our partners nor will we have control of our partners activities. The performance of our programs may be adversely affected and programs may be delayed or terminated or we may have to use funds, personnel, equipment, facilities and
other resources that we have not budgeted to undertake certain activities on our own as a result of these disagreements. Performance issues, program delays or termination or unbudgeted use of our resources may materially adversely affect our
business and financial condition.

Disputes may arise between us and a collaborative partner and may involve the issue of which of us owns
the technology and other intellectual property that is developed during a collaboration or other issues arising out of the collaborative agreements. Such a dispute could delay the program on which we are working or could prevent us from obtaining
the right to commercially exploit such developments. It could also result in expensive arbitration or litigation, which may not be resolved in our favor. Our collaborative partners could merge with or be acquired by another company or experience
financial or other setbacks unrelated to our collaboration that could, nevertheless, adversely affect us.

Risks Related to Owning Our Common Stock

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

Provisions of our certificate of incorporation, our bylaws and Delaware law
could make it more difficult for a third party to acquire us, even if doing so would be beneficial to our stockholders. In addition, we adopted a share purchase rights plan that has anti-takeover effects. The rights under the plan will 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, since the rights may be
amended to permit such an acquisition or may be redeemed by us. These provisions in our charter documents, under Delaware law, and in our rights plan could discourage potential takeover attempts and could adversely affect the market price of our
common stock. Because of these provisions, our common stockholders might not be able to receive a premium on their investment.

We expect that our
quarterly results of operations will fluctuate, and this fluctuation could cause our stock price to decline, causing investor losses.

Our quarterly operating results have fluctuated in the past and are likely to do so in the future. These fluctuations could cause our stock price to fluctuate significantly or decline. Revenue and expenses in future periods may be greater
or less than in the immediately preceding period or in the comparable period of the prior year. Some of the factors that could cause our operating results to fluctuate include:



| |  |  | termination of strategic alliances and collaborations;
| | - |  | ------------------------------------------------------



| |  |  | the success rate of our discovery efforts associated with milestones and royalties;
| | - |  | -----------------------------------------------------------------------------------



| |  |  | the ability and willingness of strategic partners and collaborators to commercialize, market, and sell royalty-bearing products or processes on expected timelines;
| | - |  | -------------------------------------------------------------------------------------------------------------------------------------------------------------------



| |  |  | our ability to enter into new agreements with potential strategic partners and collaborators or to extend the terms of our existing strategic alliance agreements
and collaborations, and the terms of any agreement of this type;
| | - |  | ----------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------



| |  |  | our need to continuously recruit and retain qualified personnel;
| | - |  | ----------------------------------------------------------------



| |  |  | our ability to successfully satisfy all pertinent regulatory requirements;
| | - |  | --------------------------------------------------------------------------



| |  |  | our ability to successfully commercialize products or processes developed independently and the demand and prices for such products or processes;
| | - |  | -------------------------------------------------------------------------------------------------------------------------------------------------



| |  |  | the cost and timing of optimization and operation of our cellulosic ethanol demonstration facility;
| | - |  | ---------------------------------------------------------------------------------------------------



| |  |  | the extent, cost and timing of any new projects for the development of commercial-scale cellulosic ethanol facilities;
| | - |  | ----------------------------------------------------------------------------------------------------------------------



| |  |  | general and industry specific economic conditions, which may affect our, and our collaborative partners, research and development expenditures; and
| | - |  | ----------------------------------------------------------------------------------------------------------------------------------------------------



| |  |  | increased expenses related to the implementation of our vertical integration strategy within biofuels.
| | - |  | ------------------------------------------------------------------------------------------------------

A large portion of our expenses, including expenses for facilities, equipment and personnel, are relatively fixed. Failure to achieve anticipated levels
of revenue could therefore significantly harm our operating results for a particular fiscal period.

Due to the possibility of fluctuations
in our revenue and expenses, we believe that quarter-to-quarter comparisons of our operating results are not a good indication of our future performance. Our operating results in some quarters may not meet the expectations of stock market analysts
and investors. In that case, our stock price would probably decline.

Our stock price has been and may continue to be particularly volatile.

The market price of our common stock has in the past been and is likely to continue to be subject to significant fluctuations. Between
January 1, 2006 and August 10, 2009, the closing market price of our common stock has ranged from a low of $0.23 to a high of $11.58. Since the completion of our merger with Celunol on June 20, 2007, the closing market price of our
common stock has ranged from $0.23 to $6.83. The closing market price of our common stock on June 30, 2009 was $0.76, and the closing price of our common stock on August 10, 2009 was $0.60. Some of the factors that may cause the market
price of our common stock to fluctuate include:



| |  |  | the entry into, or termination of, key agreements, including key collaboration agreements and licensing agreements;
| | - |  | -------------------------------------------------------------------------------------------------------------------



| |  |  | interruption or delay in the optimization and operation of our cellulosic ethanol demonstration facility;
| | - |  | ---------------------------------------------------------------------------------------------------------

warrants, including the extent to which we issue shares versus pay cash in satisfaction of any make-whole obligation arising upon conversion of some or all of the 2008 Notes or to pay interest due under the 2008 Notes; and
| | - |  | --------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------



| |  |  | period-to-period fluctuations in our financial results.
| | - |  | -------------------------------------------------------

Moreover, the stock markets in general are currently experiencing substantial volatility related to general economic conditions and may continue to experience volatility for some time. The stock markets have
experienced in the past substantial volatility that has often been unrelated to the operating performance of individual companies. These broad market fluctuations may also adversely affect the trading price of our common stock.

In the past, following periods of volatility in the market price of a companys securities, stockholders have often instituted class action
securities litigation against those companies. Such litigation, if instituted, could result in substantial costs and diversion of management attention and resources, which could significantly harm our profitability and reputation.

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.

Our officers, directors, and stockholders with at least 10% of our stock together controlled
approximately 30% of our outstanding common stock as of June 30, 2009. If these officers, directors, and principal stockholders act together, they will be able to exert a significant degree of influence over our management and affairs and
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 heavily contribute to our entering 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. This concentration of ownership could depress our stock price.
