NOTES TO FINANCIAL STATEMENTS

1. Basis of Presentation

The financial statements of Senomyx, Inc. (“Senomyx” or the “Company”) at September 30, 2006 and for the three and nine months ended September 30, 2006 and 2005 are unaudited. The unaudited financial statements have been prepared on the same basis as the Company’s audited financial statements and, in the opinion of management, include all adjustments, consisting only of normal recurring adjustments, necessary to state fairly the financial information therein. The results of operations for the three and nine months ended September 30, 2006 are not necessarily indicative of the results that may be reported for the year ended December 31, 2006. For more complete financial information, these financial statements, and the notes thereto, should be read in conjunction with the audited financial statements for the year ending December 31, 2005, including the notes thereto, included in the Company’s Annual Report on Form 10-K filed with the Securities and Exchange Commission (the “SEC”).

Use of Estimates

The preparation of financial statements in conformity with U.S. generally accepted accounting principles requires management to make estimates and assumptions that affect the reported amounts of assets and liabilities and disclosure of contingent assets and liabilities at the date of the financial statements and the reported amounts of revenues and expenses during the reporting period. Actual results could differ from those estimates.

Revenue Recognition

The Company’s revenue recognition policies are in compliance with the Staff Accounting Bulletin (“SAB”) No. 104, Revenue Recognition and Emerging Issues Task Force (“EITF”) Issue No. 00-21, Revenue Arrangements with Multiple Deliverables. Revenue is deferred for fees received before earned. Some of the Company’s agreements contain multiple elements, including research funding, cost reimbursements, milestones, and royalties.

Revenue from milestones is recognized when earned, as evidenced by written acknowledgment from the collaborator or other persuasive evidence that the milestone has been achieved, provided that (i) the milestone event is substantive and its achievability was not reasonably assured at the inception of the agreement, and (ii) the Company’s performance obligations after the milestone achievement will continue to be funded by the collaborator at a level comparable to before the milestone achievement. If both of these criteria are not met, the milestone payment is recognized over the remaining minimum period of the Company’s performance obligations under the agreement. Non-refundable license fees, if not associated with future Company performance, are recognized when received. Non-refundable license fees, if associated with future Company performance, are associated with a specific program or collaboration and recognized over the period of service for that specific program or collaboration. Amounts received for research funding are recognized as revenues as the services are performed. Royalties to be received based on product sales made by the Company’s collaborators incorporating the Company’s product, if any, will be recognized as earned. To date, the Company has not earned any royalties.

Recent Accounting Pronouncements

In June 2006, the Financial Accounting Standards Board (“FASB”) ratified EITF Issue No. 06-2, Accounting for Sabbatical Leave and Other Similar Benefits Pursuant to FASB Statement No. 43, Accounting for Compensated Absences. EITF 06-2 provides guidelines under which sabbatical leave or other similar benefits provided to an employee are considered to accumulate, as defined in FASB Statement 43. If such benefits are deemed to accumulate, then the compensation cost associated with a sabbatical or other similar benefit arrangement should be accrued over the requisite service period. The provisions of this Issue are effective for fiscal years beginning after December 15, 2006 and allow for either retrospective application or a cumulative effect adjustment to accumulated deficit approach upon adoption. The Company does not expect the adoption of EITF Issue No. 06-02 to have a material impact on its financial statements.

In June 2006, the FASB issued FASB 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 attribute for recognition and measurement of a tax position taken or expected to be taken in a tax return. FIN 48 also provides guidance on de-recognition, classification, interest and penalties, accounting in interim periods, disclosure and transition. The interpretation is effective for fiscal years beginning after December 15, 2006. The cumulative effect upon adoption of applying the provision shall be reported as an adjustment to the opening balance of retained earnings for that fiscal year,

presented separately. The Company does not expect the adoption of FIN 48 to have a material impact on its financial statements.

Stock-Based Compensation

Upon adoption of Statement of Financial Accounting Standards (“SFAS”) No. 123R, Share Based Payment (“SFAS No. 123R”), the Company has continued to use the Black-Scholes model which was previously used for the Company’s pro forma information required under SFAS No. 123, Accounting for Stock-Based Compensation. The Company’s employee stock options have various restrictions that reduce option value, including vesting provisions and restrictions on transfer and hedging, among others, and are often exercised prior to their contractual maturity. Because the Company’s employee stock options have characteristics significantly different from those of traded options, and because changes in the subjective input assumptions can materially affect the fair value estimate, in management’s opinion, the existing models do not necessarily provide a reliable single measure of the fair value of the Company’s employee stock options.

The weighted-average estimated fair value of employee stock options granted during the nine month period ended September 30, 2006 was $9.54 per share using the Black-Scholes model with the following assumptions (annualized percentages):

	Nine months ended September 30, 2006
Expected volatility	60.41	%
Risk-free interest rate	4.88	%
Dividend yield	0.0	%
Expected term	6.08 years

The weighted-average estimated fair value of employee stock purchase rights granted during the nine month period ended September 30, 2006 was $6.94 per share using the Black-Scholes model with the following assumptions (annualized percentages):

	Nine months ended September 30, 2006
Expected volatility	67.33	%
Risk-free interest rate	4.90	%
Dividend yield	0.0	%
Expected term	1.25 years

Expected volatility is based on the Company’s historical volatility and the historical volatilities of the common stock of comparable publicly traded companies. The risk-free rate for the expected term of the option is based on the average U.S. Treasury yield curve at balance sheet date for the expected term. The expected term of options granted is derived from the average midpoint between vesting and the contractual term, as described in SEC’s Staff Accounting Bulletin No. 107, Share-Based Payment. The assumptions related to expected volatility and risk-free interest rate used for the valuation of stock options under the Company’s stock plan differ from those used for the valuation of stock purchase rights under the Company’s ESPP primarily due to the difference in their respective expected lives.

As stock-based compensation expense recognized in the Statement of Operations for 2006 is based on awards ultimately expected to vest, it should be reduced for estimated forfeitures. SFAS 123R requires forfeitures to be estimated at the time of grant and revised, if necessary, in subsequent periods if actual forfeitures differ from those estimates. Pre-vesting forfeitures were estimated to be approximately 7.2% in the third quarter of 2006 based on historical experience. In the Company’s pro forma information required under SFAS 123 for the periods prior to fiscal 2006, the Company accounted for forfeitures as they occurred. Compensation expense related to stock-based compensation is recognized on a straight-line basis. Compensation expense related to stock-based compensation is allocated to research and development or general and administrative based upon the department to which the associated employee or non-employee reports.

Total estimated stock-based compensation expense, related to all of the Company’s stock-based awards granted to employees and non-employee directors, recognized for the three and nine months ended September 30, 2006 was comprised as follows (in thousands, except per share data):

	Three Months Ended September 30,			Nine Months Ended September 30,
	2006			2006
Research and development	$	(427	)	$	(1,458	)
General and administrative	(978		)	(3,380		)
Employee and non-employee director stock-based compensation expense	$	(1,405	)	$	(4,838	)

Employee and non-employee director stock-based compensation expense, per common share, basic and diluted:	$	(0.05	)	$	(0.16	)

As a result of adopting SFAS 123R, the Company’s net loss for the three and nine months ended September 30, 2006 is approximately $1.2 and $3.6 million higher, respectively, than if the Company had continued to account for share-based compensation under Accounting Principles Board (“APB”) Opinion No. 25, Accounting for Stock Issued to Employees. Basic and diluted net loss per share for the three and nine months ended September 30, 2006 are $0.04 and $0.12 higher, respectively, than if the Company continued to account for share-based compensation under APB Opinion No. 25.

Pro Forma Information under SFAS 123 for Periods Prior to Fiscal 2006

Prior to adopting the provisions of SFAS 123R, the Company recorded estimated compensation expense for employee stock options based upon their intrinsic value on the date of grant pursuant to APB Opinion No. 25, and provided the required pro forma disclosures of SFAS 123. Under APB Opinion No. 25, when the purchase price of restricted stock or the exercise price of the Company’s employee stock options equals or exceeds the fair value of the underlying stock on the date of issuance or grant, no compensation expense is recognized. In the event that stock options are granted with an exercise price below the fair value of the Company’s common stock per share on the grant date, the difference between the fair value of the Company’s common stock and the exercise price of the stock option was recorded as deferred compensation. Deferred compensation was amortized to compensation expense on an accelerated basis in accordance with Financial Accounting Standards Board Interpretation (“FIN”) No. 28, Accounting for Stock Appreciation Rights and Other Variable Stock Option or Award Plans, over the vesting period of the related options, generally four years.

Options or stock awards issued to non-employees who are not directors of the Company are recorded at their fair value in accordance with SFAS No. 123 and EITF Issue No. 96-18, Accounting for Equity Instruments That Are Issued to Other Than Employees for Acquiring or in Conjunction with Selling Goods or Services, and are periodically revalued as the options vest and are recognized as expense over the related service period.

As required under SFAS No. 123, for purposes of pro forma disclosures, the estimated fair value of the options is amortized to expense over the vesting period of the related options. The Company’s pro forma information follows (in thousands, except per share data):

	Three Months Ended September 30,			Nine Months Ended September 30,
	2005			2005
Net loss as reported	$	(4,663	)	$	(14,440	)
Add: Stock-based employee compensation expense included in reported net loss	529			2,039
Deduct: Total stock-based compensation expense determined under fair value-based method for all awards	(1,540		)	(5,180		)
Net loss pro forma	$	(5,674	)	$	(17,581	)

Net loss per share pro forma	$	(0.22	)	$	(0.70	)

Net Loss Per Share

The Company calculates net loss per share in accordance with SFAS No. 128, Earnings Per Share, and SAB No. 98. Basic earnings per share (“EPS”) is calculated by dividing the net income or loss by the weighted average number of common shares outstanding for the period, less weighted average unvested common shares subject to repurchase. Diluted EPS is computed by dividing the net income or loss by the weighted average number of common share equivalents

outstanding for the period determined using the treasury-stock method. For purposes of this calculation, convertible preferred stock, options and warrants are considered to be common stock equivalents and are only included in the calculation of diluted earnings per share when their effect is dilutive. Under the provisions of SAB No. 98, common shares issued for nominal consideration, if any, would be included in the per share calculations as if they were outstanding for all periods presented. No common shares have been issued for nominal consideration.

The following table sets forth the computation of basic and diluted net loss per share for the respective periods.

Comprehensive Loss

Comprehensive loss represents net loss adjusted for the change during the periods presented in unrealized gains and losses on available-for-sale securities less reclassification adjustments for realized gains or losses included in net loss. The accumulated unrealized gains or losses are reported as accumulated other comprehensive loss as a separate component of stockholders’ equity. Comprehensive loss is as follows (in thousands):

	Three Months Ended September 30,						Nine Months Ended September 30,
	2006			2005			2006			2005

Comprehensive loss	$	(5,005	)	$	(4,675	)	$	(17,794	)	$	(14,442	)

Leasehold Incentive Obligation

In conjunction with the lease agreement covering the new facility to be occupied by the Company, the Company received a tenant improvement allowance not to exceed $9.9 million. As the tenant improvements are constructed, the Company records both the covered tenant improvements (as fixed assets) and an offsetting incentive lease obligation on the Company’s balance sheet. Once the Company takes occupancy of the new facility, the Company will record depreciation expense to depreciate the tenant improvements and record an offsetting reduction to rent expense (to amortize the leasehold incentive obligation) over the initial term of the lease, in accordance with FASB Technical Bulletin 88-1, Issues Relating to Accounting for Leases.

Reclassifications

Certain reclassifications have been made to amounts included in the prior period’s financial statements to conform to the current period presentation.

2. Stockholders’ Equity

Equity Incentive Plan

During 1999, the Company adopted the 1999 Equity Incentive Plan (the “Plan”), which provides for the grant of incentive and non-statutory stock options and restricted stock purchase rights to employees, directors and consultants of the Company.

Options granted under the Plan generally expire no later than ten years from the date of grant (five years for a 10% stockholder). Options generally vest and become fully exercisable over a period of four years. In certain cases, grants to officers, directors and consultants can be made fully exercisable at the date of grant. The exercise price of incentive stock options must be equal to at least the fair value of the Company’s common stock on the date of grant, and the exercise price of non-statutory stock options may be no less than 85% of the fair value of the Company’s common stock on the date of grant. The exercise price of any option granted to a 10% stockholder may be no less than 110% of the fair value of the Company’s common stock on the date of grant. As of September 30, 2006, approximately 2.4 million shares were available for future grant under the Plan.

The following is a summary of stock option and stock award activity under the equity incentive plan through September 30, 2006:

	Number of Shares		Weighted Average Exercise Price

Outstanding at January 1, 2006	2,483,417		$	6.15
Granted	1,340,890		$	15.51
Exercised	(245,333	)	$	5.78
Cancelled	(11,319	)	$	10.26

Outstanding at September 30, 2006	3,567,655		$	9.68

The following is a further breakdown of the options outstanding as of September 30, 2006:

		Options Outstanding			Options Vested and Exercisable
Range of Exercise Prices	Number of Options	Weighted Average Remaining Contractual Life	Weighted Average Exercise Price		Number of Options	Weighted Average Exercise Price

$ 0.74-6.00	542,382	6.55	$	0.91	417,011	$	0.94
$ 6.02-6.02	817,116	7.50	$	6.02	425,480	$	6.02
$ 6.30-9.50	723,814	8.19	$	8.69	258,490	$	8.72
$ 11.78-15.89	533,493	9.06	$	13.69	95,122	$	13.03
$ 16.25-18.99	950,850	9.32	$	16.33	9,352	$	18.14

	3,567,655				1,205,455

The aggregate intrinsic value of options exercised during the nine month period ended September 30, 2006, outstanding at September 30, 2006 and exercisable at September 30, 2006 was approximately $2.1 million, $21.2 million and $11.9 million, respectively.

Employee Stock Purchase Plan

During 2004, the Company adopted the 2004 Employee Stock Purchase Plan (the “Purchase Plan”), which allows all eligible employees to purchase shares of the Company’s common stock at the lower of: (i) 85% of the fair market value on the first day of a two-year offering period; or (ii) 85% of the fair market value on the last date of each six-month purchase period within the two-year offering period. Employees may authorize the Company to withhold up to 15% of their compensation during any purchase period, subject to certain limitations. The Purchase Plan authorizes up to 673,096 shares to be granted.

3. Subsequent Events

Ajinomoto Collaboration

Effective October 6, 2006, the Company entered into a Collaborative Research, Commercialization and License Agreement with Ajinomoto Co., Inc. for the discovery and commercialization of specified natural flavor ingredients. Under the terms of the agreement, Ajinomoto has agreed to pay the Company research funding for up to three years based on research progress during the collaborative period. In addition, the Company is eligible to receive payments upon achievement of specific milestones. The combined total of research funding and milestone payments could exceed $2.8 million if all milestones are met. Upon commercialization, the Company will receive payments based on sales of products containing new flavor ingredients developed under the agreement.

The Regents of the University of California License Agreement

In March 2000, the Company entered into a license agreement with The Regents of the University of California under which the Company obtained exclusive rights to certain technologies held by the University of California that are involved in the biology of taste, including specified receptors in two taste receptor families, T1Rs, and T2Rs. On October 11, 2006, the Company entered into an amended and restated license agreement to include certain additional related technologies.

As with the original license agreement, the amended and restated license agreement calls for annual maintenance fees and royalties on sales of any products developed using the technologies licensed under the agreement. Royalties will accrue in each country for as long as there exists a valid patent claim covering a product developed under the agreement. The agreement will remain in effect until the expiration of the last to expire patent licensed under the agreement.

ITEM 2. MANAGEMENT’S DISCUSSION AND ANALYSIS OF FINANCIAL CONDITION AND

RESULTS OF OPERATIONS

The following discussion and analysis of our financial condition and results of operations should be read in conjunction with our unaudited financial statements and related notes included in this quarterly report on Form 10-Q and the audited financial statements and notes thereto as of and for the year ended December 31, 2005 included with our Annual Report on Form 10-K filed with the Securities and Exchange Commission, or SEC. Operating results are not necessarily indicative of results that may occur in future periods.

Certain statements contained in this quarterly report on Form 10-Q, including statements regarding the development, growth and expansion of our business, our intent, belief or current expectations, primarily with respect to our future operating performance, and the products we expect to offer and other statements regarding matters that are not historical facts, are “forward-looking statements” within the meaning of Section 27A of the Securities Act of 1933, as amended, or Securities Act, and Section 21E of the Securities Exchange Act of 1934, as amended, or Exchange Act, and are subject to the “safe harbor” created by these sections. Future filings with the SEC, future press releases and future oral or written statements made by us or with our approval, which are not statements of historical fact, may also contain forward-looking statements. Because such statements include risks and uncertainties, many of which are beyond our control, actual results may differ materially from those expressed or implied by such forward-looking statements. Some of the factors that could cause actual results to differ materially from those expressed or implied by such forward-looking statements can be found under the caption “Risk Factors,” and elsewhere in this quarterly report on Form 10-Q. Readers are cautioned not to place undue reliance on forward-looking statements.

We are a leading company focused on using proprietary taste receptor-based assays and screening technologies to discover and develop novel flavors, flavor enhancers and taste modulators for the packaged food and beverage industry. We believe our flavor ingredients will enable packaged food and beverage companies to improve the nutritional profile of their products while maintaining or enhancing taste and may generate cost of goods savings. We license our flavor ingredients to our collaborators on an exclusive or co-exclusive basis, which we believe we will provide these companies with the ability to differentiate their products. We have entered into product discovery and development collaborations with six of the world’s leading packaged food and beverage companies: Ajinomoto, Cadbury Schweppes, Campbell Soup Company, The Coca-Cola Company, Kraft Foods Global, Inc. and Nestlé SA. We currently anticipate that we will derive all of our revenues from existing and future collaborations. Depending upon the collaboration, our existing collaboration agreements provide for upfront fees, research and development funding, reimbursement of certain regulatory costs, milestone payments based upon our achievement of research or development goals and, in the event of commercialization, royalties on future sales of consumer products incorporating our flavors, flavor enhancers or taste modulators. Our current programs focus on the development of savory, sweet and salt flavor enhancers and bitter taste modulators.

We have incurred significant losses since our inception in 1998 and, as of September 30, 2006, our accumulated deficit was $122.0 million. We expect to incur additional losses over at least the next two years as we continue to develop flavors, flavor enhancers and taste modulators. Our results of operations have fluctuated from period to period and likely will continue to fluctuate substantially in the future based upon:

· termination of any of our product discovery and development collaboration agreements;

· our receipt of milestone payments in any particular period;

· variability of our stock-based compensation expense in conjunction with fluctuations of our stock price;

· our ability to discover and develop new flavors, flavor enhancers and taste modulators or the ability of our product discovery and development collaborators to incorporate them into their products;

· our ability to enter into new, or extend existing, product discovery and development collaborations and technology collaborations;

· the demand for our collaborators’ products containing our flavors, flavor enhancers and taste modulators;

· the ability and willingness of collaborators to commercialize products incorporating our flavors, flavor enhancers and taste modulators on expected timelines, or at all;

· our ability, or our collaborators’ ability, to successfully satisfy all pertinent regulatory requirements; and

· general and industry specific economic conditions, which may affect our collaborators’ research and development expenditures.

In October 2006, we entered into a Collaborative Research, Commercialization and License Agreement with Ajinomoto Co., Inc. for the discovery and commercialization of specified natural flavor ingredients. Under the terms of the agreement, Ajinomoto has agreed to pay us research funding for up to three years based on research progress during the collaborative period. In addition, we are eligible to receive payments upon achievement of specific milestones. The combined total of research funding and milestone payments could exceed $2.8 million if all milestones are met. Upon commercialization, we will receive payments based on sales of products containing new flavor ingredients developed under the agreement.

In March 2000, we entered into a license agreement with The Regents of the University of California under which we obtained exclusive rights to certain technologies held by the University of California that are involved in the biology of taste, including specified receptors in two taste receptor families, T1Rs, and T2Rs. In October 2006, we entered into an amended and restated license agreement to include certain additional related technologies. As with the original license agreement, the amended and restated license agreement calls for annual maintenance fees and royalties on sales of any products developed using the technologies licensed under the agreement. Royalties will accrue in each country for as long as there exists a valid patent claim covering a product developed under the agreement. The agreement will remain in effect until the expiration of the last to expire patent licensed under the agreement.

Results of Operations

Three Months Ended September 30, 2006 and 2005

Revenue Under Collaboration Agreements

We recorded revenue of $3.2 million and $2.1 million during the three month periods ended September 30, 2006 and 2005, respectively. Research and development payments and payments of upfront license fees under collaborations with Ajinomoto, Cadbury Schweppes, Campbell Soup, Coca-Cola, Kraft Foods, and Nestlé accounted for 100% of total revenue for the three months ended September 30, 2006. Research and development payments and payments of upfront license fees under collaborations with Cadbury Schweppes, Campbell Soup, Coca-Cola, Kraft Foods, and Nestlé, accounted for 100% of total revenue for the three months ended September 30, 2005.

Research and Development Expenses

Our research and development expenses (including stock-based compensation expenses charged to research and development) were $6.1 million and $4.7 million for the three months ended September 30, 2006 and 2005, respectively. A comparison of research and development expenses by category is as follows (in thousands):

	Three months ended September 30,
	2006		2005
Salaries and personnel	$	2,197	$	1,684
Facilities and depreciation	1,177		1,043
Research and development supplies	1,019		885
Outside services	847		250
Patent and licensing	20		282
Miscellaneous	109		82
Total research and development expenses (excluding non-cash stock based compensation)	5,369		4,226

Non-cash stock-based compensation	774		432
Total research and development expenses	$	6,143	$	4,658

Salaries and Personnel. Our expenses for research and development personnel, including consultants, were $2.2 million and $1.7 million for the three months ended September 30, 2006 and 2005, respectively. The increase of $513,000 was primarily due to an increase in payroll expense of approximately $349,000, the addition of a bonus accrual expense of approximately $112,000, and an increase in employee benefits expense of approximately $72,000, partially offset by a decrease in recruiting and relocation expense of approximately $25,000. Our research and development staff increased from an average of 61 for the three months ended September 30, 2005 to an average of 83 for the three months ended September 30, 2006. The increase in payroll expense and employee benefits expense reflects the addition of employees whose functions

support the continuing optimization of product candidates from our discovery and development programs and the impact of annual merit, cost of living and promotion salary increases. We accrue for annual bonuses when we determine that awarding of an annual bonus is probable and reasonably estimable. In previous years, we accrued for the entirety of the annual bonus in the fourth quarter, as we did not believe that the awarding of an annual bonus was either probable or reasonably estimable until that time. Based on our recent history of awarding annual bonuses for 2004 and 2005 services, the bonus accrual reflects the probability of an annual bonus being awarded for 2006 services, pro rated for service through September 30, 2006.

Facilities and Depreciation. Our facilities and depreciation expenses were $1.2 million and $1.0 million for the three months ended September 30, 2006 and 2005, respectively. The increase of $134,000 was primarily attributable to an increase in depreciation expense due to new scientific equipment being placed in service and an increase in repair costs and service contracts for scientific equipment, partially offset by a decrease in rent expense due to the modification of the lease agreement covering our current facilities.

Research and Development Supplies. Our expenses for supplies used in research and development were $1.0 million and $885,000 for the three months ended September 30, 2006 and 2005, respectively. The increase of $134,000 was primarily attributable to increased expenditures for scientific supplies associated with increased screening activities.

Outside Services. Our outside services expenses were $847,000 and $250,000 for the three months ended September 30, 2006 and 2005, respectively. The increase of $597,000 was primarily attributable to an increase in costs incurred for chemistry and product development outsourcing.

Patent and Licensing. Our patent and licensing expenses were $20,000 and $282,000 for the three months ended September 30, 2006 and 2005, respectively. The decrease of $262,000 was primarily attributable to reduced outside patent and trademark expenses in the third quarter of 2006 as compared to the third quarter of 2005.

Non-cash Stock-based Compensation. Our non-cash stock-based compensation expenses were $774,000 and $432,000 for the three months ended September 30, 2006 and 2005, respectively. The increase of $342,000 was primarily attributable to an increase in compensation expense in 2006 compared to 2005 for stock options granted to employees, partially offset by a decrease in compensation expense in 2006 compared to 2005 for stock options granted to non-employees. The increase in employee-related stock-based compensation expense is due to the adoption of SFAS 123R in the first quarter of 2006.

General and Administrative Expenses

Our general and administrative expenses (including stock-based compensation expenses charged to general and administrative) were $3.1 million and $2.4 million for the three months ended September 30, 2006 and 2005, respectively. The $711,000 increase in expenses from the three months ended September 30, 2005 to 2006 was primarily attributable to an increase in non-cash stock-based compensation expense of approximately $462,000, an increase in payroll expense of approximately $184,000, and the addition of a bonus accrual expense of approximately $119,000. The increase in non-cash stock-based compensation expense is due to the adoption of SFAS 123R in the first quarter of 2006, offset by a decrease in amortization of deferred compensation and compensation expense for stock options granted to non-employees. The increase in payroll expense was due to the impact of annual merit, cost of living and promotion salary increases and to increased headcount. As with research and development salaries and personnel expenses, the bonus accrual reflects the probability of an annual bonus being awarded for 2006 services.

Interest Income (Expense)

Interest income was $1.0 million and $257,000 for the three months ended September 30, 2006 and 2005, respectively. The increase of $770,000 was primarily attributable to our higher average cash balances for the three months ended September 30, 2006, primarily as a result of our November 2005 public offering, which generated higher interest earnings on those balances.

Nine Months Ended September 30, 2006 and 2005

Revenue Under Collaboration Agreements

We recorded revenue of $8.8 million and $7.1 million during the nine month periods ended September 30, 2006 and 2005, respectively. Research and development payments and payments of upfront license fees under collaborations with Ajinomoto, Cadbury Schweppes, Campbell Soup, Coca-Cola, Kraft Foods, and Nestlé accounted for approximately 100% of total revenue for the nine months ended September 30, 2006. Research and development payments, including certain product candidate development reimbursement costs and upfront license fees, and milestones under collaborations with Cadbury Schweppes, Campbell Soup, Coca-Cola, Kraft Foods, and Nestlé, accounted for 100% of total revenue for the nine months ended September 30, 2005.

Research and Development Expenses

Our research and development expenses (including stock-based compensation expenses charged to research and development) were $19.0 million and $14.8 million for the nine months ended September 30, 2006 and 2005, respectively. A comparison of research and development expenses by category is as follows (in thousands):

	Nine months ended September 30,
	2006		2005
Salaries and personnel	$	6,765	$	5,451
Facilities and depreciation	3,443		3,326
Research and development supplies	2,860		2,051
Outside services	1,674		460
Patent and licensing	1,366		745
Miscellaneous	549		362

Non-cash stock-based compensation	2,321		2,402
Total research and development expenses	$	18,978	$	14,797

Salaries and Personnel. Our expenses for research and development personnel, including consultants, were $6.8 million and $5.5 million for the nine months ended September 30, 2006 and 2005, respectively. The increase of $1.3 million was primarily due to increases in payroll expense of approximately $703,000, the addition of a bonus accrual expense of approximately $309,000, an increase in employee benefits expense of approximately $166,000, and an increase in travel-related expenses of approximately $101,000. Our research and development staff increased from an average of 59 for the nine months ended September 30, 2005 to an average of 76 for the nine months ended September 30, 2006. The increases in payroll expense, employee benefits expense and travel-related expenses reflects the addition of employees whose functions support the continuing optimization of product candidates from our discovery and development programs and the impact of annual merit, cost of living and promotion salary increases. We accrue for annual bonuses when we determine that awarding of an annual bonus is probable and reasonably estimable. In previous years, we accrued for the entirety of the annual bonus in the fourth quarter, as we did not believe that the awarding of an annual bonus was either probable or reasonably estimable until that time. Based on our recent history of awarding annual bonuses for 2004 and 2005 services, the bonus accrual reflects the probability of an annual bonus being awarded for 2006 services, pro rated for service through September 30, 2006.

Facilities and Depreciation. Our facilities and depreciation expenses were $3.4 million and $3.3 million for the nine months ended September 30, 2006 and 2005, respectively. The increase of $117,000 was primarily attributable to an increase in depreciation expense due to new scientific equipment being placed into service, partially offset by a decrease in rent expense due to the modification of the lease agreement covering our current facilities.

Research and Development Supplies. Our expenses for supplies used in research and development were $2.9 million and $2.1 million for the nine months ended September 30, 2006 and 2005, respectively. The increase of $809,000 was primarily attributable to increased expenditures for scientific supplies and compound acquisition associated with increased screening activities.

Outside Services. Our outside services expenses were $1.7 million and $460,000 for the nine months ended September 30, 2006 and 2005, respectively. The increase of $1.2 million was primarily attributable to an increase in costs incurred for chemistry and product development outsourcing.

Patent and Licensing. Our patent and licensing expenses were $1.4 million and $745,000 for the nine months ended September 30, 2006 and 2005, respectively. The increase of $621,000 was primarily attributable to certain foreign patent filing activities commencing in the fourth quarter of 2005 and completed in the second quarter of 2006.

Non-cash Stock-based Compensation. Our non-cash stock-based compensation expenses were $2.3 million and $2.4 million for the nine months ended September 30, 2006 and 2005, respectively. The decrease of $81,000 was primarily attributable to a decrease in compensation expense in 2006 compared to 2005 for stock options granted to non-employees, partially offset by an increase in compensation expense in 2006 compared to 2005 for stock options granted to employees. The increase in employee-related stock-based compensation expense is due to the adoption of SFAS 123R in the first quarter of 2006.

General and Administrative Expenses

Our general and administrative expenses (including stock-based compensation expenses charged to general and administrative) were $10.5 million and $7.5 million for the nine months ended September 30, 2006 and 2005, respectively. The $3.0 million increase in expenses from the nine months ended September 30, 2005 to 2006 was primarily attributable to an increase in non-cash stock-based compensation expense of approximately $1.2 million, an increase in payroll expenses of approximately $662,000, an increase in consulting expenses of approximately $494,000, the addition of a bonus accrual expense of approximately $354,000, and an increase in recruiting and relocation expenses of approximately $213,000. The increase in non-cash stock-based compensation expense is due to the adoption of SFAS 123R in the first quarter of 2006, offset by a decrease in amortization of deferred compensation and compensation expense for stock options granted to non-employees. The increases in expenses for payroll excluding the bonus accrual and in expenses for recruiting and relocation were due to the impact of annual merit, cost of living and promotion salary increases and to increased headcount. The increase in consulting expenses was due to one-time consulting expenses. As with research and development salaries and personnel expense, the bonus accrual reflects the probability of an annual bonus being awarded for 2006 services.

Interest Income (Expense)

Interest income was $2.8 million and $732,000 for the nine months ended September 30, 2006 and 2005, respectively. The increase of $2.1 million was primarily attributable to our higher average cash balances for the nine months ended September 30, 2006, primarily as a result of our November 2005 public offering, which generated higher interest earnings on those balances.

Liquidity and Capital Resources

Since our inception, we have financed our business primarily through private and public placements of stock, research and development payments under our product discovery and development collaborations with Ajinomoto, Cadbury, Schweppes, Campbell Soup, Coca-Cola, Kraft Foods, and Nestlé, and interest income. As of September 30, 2006, we had received in excess of $167.2 million in proceeds from the sales of common and preferred stock. In addition, we had received $51.6 million in non-refundable license fees, research and development payments, cost reimbursements and milestone payments from our collaboration agreements, and $6.5 million in interest income. Over the remaining life of our current collaboration agreements, we expect to receive an additional $23.6 million in non-refundable research and development payments from our collaborators. In addition, we may receive payments in the event we achieve research or development milestones and royalty payments in the event our collaborators commercialize products incorporating our flavors, flavor enhancers and taste modulators.

At September 30, 2006, we had $77.6 million in cash, cash equivalents and investments available-for-sale as compared to $83.8 million at December 31, 2005, a decrease of $6.2 million. This overall decrease resulted primarily from the use of cash to fund our operations and to purchase property and equipment, partially offset by the receipt of proceeds of $2.3 million from the issuance of common stock through the exercise of employee and non-employee stock options and from purchases of stock from the employee stock purchase plan.

Our future capital uses and requirements depend on numerous forward-looking factors. These factors may include, but are not limited to, the following:

· the rate of progress and cost of research and development activities;
· the number and scope of our research activities;

·      the costs of filing, prosecuting, defending and enforcing any patent claims and other intellectual property rights;
·      our ability to establish and maintain product discovery and development collaborations;
·      the effect of competing technological and market developments;
·      the terms and timing of any collaborative, licensing and other arrangements that we may establish; and
·      the extent to which we acquire or in-license new products, technologies or businesses.

We believe our available cash, cash equivalents, investments and existing sources of funding will be sufficient to satisfy our anticipated operating and capital requirements through at least the next 12 months.

Until we can generate significant cash from our operations, we expect to continue to fund our operations with existing cash resources that were primarily generated from the proceeds of offerings of our equity securities and research and development payments and milestone payments under our product discovery and development collaborations. Under our existing collaboration agreements, assuming all remaining milestones are achieved and we receive all remaining research and development funding, we may be entitled to payments which total up to $36.6 million. In the next three months (through December 31, 2006), we anticipate receiving $2.3 million in non-refundable research and development payments. We may not receive the payments if the collaborations are terminated or not renewed, or if we do not achieve the milestones set forth in the collaboration agreements. In addition, the timing of the receipt of milestone payments in particular is uncertain, as we may achieve milestones significantly earlier or later than we currently expect. We continue to pursue additional collaborations, which could result in additional revenue. We may not recognize revenues for research and development funding or milestones if the collaborations are terminated, or if we do not achieve the milestones set forth in the collaboration agreements.

Operating Activities

Operating activities used cash of $5.3 million for the nine months ended September 30, 2006 compared to $10.7 million for the nine months ended September 30, 2005. Operating cash flow in 2006 compared to the prior year period reflects an increase in our net loss of $3.4 million. Non-cash expenses for the nine months ended September 30, 2006 increased $633,000 to $6.1 million from $5.5 million for the nine months ended September 30, 2005. This increase was primarily due to an increase in the stock-based compensation expense of approximately $3.0 million. This increase was partially offset by a decrease in amortization of deferred compensation for stock option grants to employees of approximately $1.9 million, due to the adoption of SFAS 123R. Net decreases in other assets provided cash of $296,000 during the nine months ended September 30, 2006, while net increases in other assets used cash of $250,000 during the nine months ended September 30, 2005. Net changes in accounts payable, accrued expenses and other current liabilities provided cash of $6,000 and used cash of $884,000 for the nine months ended September 30, 2006 and 2005, respectively. Net changes in deferred revenue provided cash of $4.2 million in the nine months ended September 30, 2006, and used cash of $607,000 in the nine months ended September 30, 2005. Net decreases in deferred rent over the nine months ended September 30, 2006 and 2005 used cash of $151,000 and $44,000, respectively. Additionally, reimbursements from the lessor of the Alexandria Lease provided cash of $2.1 million during the nine months ended September 30, 2006. This provision is offset by a corresponding use of cash to purchase property and equipment, an investing activity for cash flow statement purposes. This provision of cash is associated with the construction of tenant improvements for the Alexandria Lease, and as such, is not expected to be of a recurring nature in future periods after 2006. For further discussion of the Alexandria Lease, please see below.

Investing Activities

Investing activities used cash of $38.5 million for the nine months ended September 30, 2006 and provided cash of $1.3 million for the nine months ended September 30, 2005. Cash used in the nine months ended September 30, 2006 reflects the purchases of available-for-sale securities to obtain higher rates of interest income, partially offset by the maturities of available-for-sale securities. Cash used in the nine months ended September 30, 2006 also reflects the use of $3.9 million to purchase property and equipment. Included in this $3.9 million is $2.1 million used to construct tenant improvements at our new facility. This use of cash is offset by a corresponding provision of cash, shown as increases in leasehold incentive obligation, an operating activity for cash flow statement purposes. This use of cash is associated with the construction of tenant improvements at our new facility, and as such, is not expected to be of a recurring nature in future periods after 2006. Cash provided in the nine months ended September 30, 2005 primarily reflects the maturities, net of purchases, of available-for-sale securities to fund increased operating expenses.

Financing Activities

Financing activities provided cash of $2.3 million and $1.2 million for the nine months ended September 30, 2006 and 2005, respectively. Cash provided by financing activities in the nine months ended September 30, 2006 and 2005 reflects the net proceeds from the sale of common stock primarily from the exercise of employee and non-employee stock options and from purchases of stock from the employee stock purchase program.

Contractual Obligations

As of September 30, 2006 future minimum payments due under our contractual obligations are as follows (in thousands):

	Payments Due by Period
	Total		Less than 1 year		1-3 years		4-5 years		After 5 years
Operating leases	$	27,513	$	2,223	$	4,784	$	5,035	$	15,471
License payments	172		48		52		36		36
Total	$	27,685	$	2,271	$	4,836	$	5,071	$	15,507

In January 2006, we entered into a lease with ARE-NEXUS CENTRE II, LLC (the “Alexandria Lease”), pursuant to which we will lease approximately 64,000 square feet of real estate space in San Diego, California, consisting of laboratory and office space. The lease is targeted to commence in the fourth quarter of 2006, with rent targeted to commence April 1, 2007 and end on February 28, 2017. Annual rent payments are expected to be approximately $2.3 million, subject to annual rent increases of 3%.

In connection with the execution of the Alexandria Lease, also in January 2006 we entered into the Torrey Pines Lease Amendment with ARE-11099 North Torrey Pines, LLC for our current property to provide for the extension of the lease term, subject to certain limitations, until we move all of our operations to the new location, which we expect to occur in the fourth quarter of 2006. As a result of entering into two leases with the same landlord, we anticipate that we will be able to avoid making rent payments on two facilities at the same time. Furthermore, we anticipate a period of three months in early 2007 when we will not be required to make a payment for rent.

The Alexandria Lease is not expected to have a significant impact on our anticipated operating and capital requirements.

As of September 30, 2006, we had no long-term debt obligations.

Off-Balance Sheet Arrangements

As of September 30, 2006 and 2005, we did not have any relationships with unconsolidated entities or financial partnerships, such as entities often referred to as special purpose or structured finance entities, which would have been established for the purposes of facilitating off-balance sheet arrangements or other contractually narrow or limited purposes. As such, we are not materially exposed to any financing, liquidity, market or credit risk that could arise if we had engaged in these relationships.

Critical Accounting Policies

Our discussion and analysis of our financial condition and results of operations are based on our financial statements, which have been prepared in accordance with U.S. generally accepted accounting principles, or GAAP. The preparation of these financial statements requires management to make estimates and judgments that affect the reported amounts of assets, liabilities and expenses and related disclosure of contingent assets and liabilities. On an ongoing basis, we evaluate these estimates, including those related to revenue recognition, long-lived assets, accrued liabilities, and income taxes. These estimates are based on historical experience and various other assumptions that we believe to be reasonable under the circumstances, the results of which form the basis for judgments about the carrying values of assets and liabilities. Actual results may differ from these estimates under different assumptions or conditions.

Revenue Recognition

Our revenue recognition policies are in compliance with the Staff Accounting Bulletin, or SAB, No. 104, Revenue Recognition and Emerging Issues Task Force, or EITF, Issue No. 00-21, Revenue Arrangements with Multiple Deliverables. Revenue is deferred for fees received before earned. Some of our agreements contain multiple elements, including upfront fees, research funding, milestones, and royalties.

Revenue from milestones is recognized when earned, as evidenced by written acknowledgement from the collaborator or other persuasive evidence that the milestone has been achieved, provided that (i) the milestone event is substantive and its achievability was not reasonably assured at the inception of the agreement, and (ii) our performance obligations after the milestone achievement will continue to be funded by the collaborator at a level comparable to before the milestone achievement. If both of these criteria are not met, the milestone payment is recognized over the remaining minimum period of our performance obligations under the agreement. Non-refundable upfront fees, if any, not associated with our future performance, will be recognized when received. Non-refundable upfront fees associated with our future performance are deferred and recognized over the remaining period of our future performance. Non-refundable license fees associated with future performance involving a specific program or collaboration are recognized over the period of service for that specific program or collaboration. Amounts received for research funding are recognized as revenues as the services are performed. Revenue from cost reimbursements is recognized when earned, as evidenced by written acknowledgement from the collaborator or other persuasive evidence. Royalties to be received based on product sales made by our collaborators incorporating our product, if any, will be recognized as earned. To date, we have not earned any royalties.

Stock-based Compensation Expense

In December 2004, the Financial Accounting Standards Board, or FASB, issued Statement of Financial Accounting Standards, or SFAS, No. 123R, Share-Based Payment, which requires companies to expense the estimated fair value of employee stock options and similar awards. This statement is a revision to SFAS No. 123, Accounting for Stock-Based Compensation, and supersedes Accounting Principles Board, or APB, Opinion No. 25, Accounting for Stock Issued to Employees, and amends FASB Statement No. 95, Statement of Cash Flows. The accounting provisions of SFAS No. 123R were effective for us beginning the first quarter of fiscal 2006.

We grant options to purchase our common stock to our employees and directors under our stock option plan. Eligible employees can also purchase shares of our common stock under the employee stock purchase plan at the lower of: (i) 85% of the fair market value on the first day of a two-year offering period; or (ii) 85% of the fair market value on the last date of each six-month purchase period within the two-year offering period. The benefits provided under these plans are stock-based payments subject to the provisions of revised SFAS 123R. Effective January 1, 2006, we use the fair value method to apply the provisions of SFAS 123R with a modified prospective application which provides for certain changes to the method for valuing stock-based compensation. The valuation provisions of SFAS 123R apply to new awards and to awards that are outstanding on the effective date and subsequently modified or cancelled. Under the modified prospective application, prior periods are not revised for comparative purposes. Stock-based compensation expense recognized under SFAS 123R for the three and nine months ended September 30, 2006 was $1.4 million and $4.8 million, respectively. At September 30, 2006, total unrecognized estimated compensation expense related to non-vested stock options granted prior to that date was $11.6 million, which is expected to be recognized over a weighted average period of 2.1 years. Total stock options granted to employees and non-employee directors during the three months ended September 30, 2006 and September 30, 2005 represented 0.1% of outstanding shares as of the end of each fiscal quarter. Total stock options granted to employees and non-employee directors during the nine months ended September 30, 2006 and September 30, 2005 represented 4.1% and 2.9% of outstanding shares as of the end of each fiscal quarter, respectively.

Both prior and subsequent to the adoption of SFAS 123R, we estimated the value of stock-based awards on the date of grant using the Black-Scholes option pricing model. Prior to the adoption of SFAS 123R, the value of each stock-based award was estimated on the date of grant using the Black-Scholes model for the pro forma information required to be disclosed under SFAS 123. The determination of the fair value of stock-based payment awards on the date of grant using an option-pricing model is affected by our stock price as well as assumptions regarding a number of complex and subjective variables. These variables include, but are not limited to, our expected stock price volatility over the term of the awards, risk-free interest rate and the expected term of the awards.

If factors change and we employ different assumptions in the application of SFAS 123R in future periods, the compensation expense that we record under SFAS 123R may differ significantly from what we have recorded in the current period. Therefore, we believe it is important for investors to be aware of the high degree of subjectivity involved when using option pricing models to estimate stock-based compensation under SFAS 123R. Option-pricing models were developed for use in estimating the value of traded options that have no vesting or hedging restrictions, are fully transferable and do not cause dilution. Because our stock-based payments have characteristics significantly different from those of freely traded options, and because changes in the subjective input assumptions can materially affect our estimates of fair values, in our opinion, existing valuation models, including the Black-Scholes model, may not provide reliable measures of the fair values of our stock-based compensation. Consequently, there is a risk that our estimates of the fair values of our stock-based

compensation awards on the grant dates may bear little resemblance to the actual values realized upon the exercise, expiration, early termination or forfeiture of those stock-based payments in the future. Certain stock-based payments, such as employee stock options, may expire worthless or otherwise result in zero intrinsic value as compared to the fair values originally estimated on the grant date and reported in our financial statements. Alternatively, value may be realized from these instruments that is significantly in excess of the fair values originally estimated on the grant date and reported in our financial statements. There is currently no market-based mechanism or other practical application to verify the reliability and accuracy of the estimates stemming from these valuation models, nor is there a means to compare and adjust the estimates to actual values. Although the fair value of employee stock-based awards is determined in accordance with SFAS 123R and the Securities and Exchange Commission’s Staff Accounting Bulletin No. 107 (SAB 107) using an option-pricing model, that value may not be indicative of the fair value observed in a willing buyer/willing seller market transaction.

Estimates of stock-based compensation expenses are significant to our financial statements, but these expenses are based on the aforementioned option valuation model and will never result in the payment of cash by us. For this reason, we do not view stock-based compensation as related to our operational performance.

The guidance in SFAS 123R and SAB 107 is relatively new, and best practices are not well established. The application of these principles may be subject to further interpretation and refinement over time. There are significant differences among valuation models, and there is a possibility that we will adopt different valuation models in the future. This may result in a lack of consistency in future periods and materially affect the fair value estimate of stock-based payments. It may also result in a lack of comparability with other companies that use different models, methods and assumptions.

Theoretical valuation models and market-based methods are evolving and may result in lower or higher fair value estimates for stock-based compensation. The timing, readiness, adoption, general acceptance, reliability and testing of these methods is uncertain. Sophisticated mathematical models may require voluminous historical information, modeling expertise, financial analyses, correlation analyses, integrated software and databases, consulting fees, customization and testing for adequacy of internal controls. Market-based methods are emerging that, if employed by us, may dilute our earnings per share and involve significant transaction fees and ongoing administrative expenses. The uncertainties and costs of these extensive valuation efforts may outweigh the benefits to investors.

For purposes of estimating the fair value of stock options granted to employees and non-employee directors during the nine months ended September 30, 2006 using the Black-Scholes model, we have made a subjective estimate regarding our stock price volatility (weighted average of 60.41% for the nine months ended September 30, 2006). We used an average of the historical volatility of our stock for the period our stock has been publicly traded and the historical volatilities of the common stock of several publicly traded companies management feels are comparable to us, consistent with the guidance in SFAS 123R and SAB 107. If our stock price volatility assumption were increased to 70%, the weighted average estimated fair value of stock options granted during the nine months ended September 30, 2006 would increase by $0.94 per share, or 9.8%.

The risk-free interest rate for the expected term of the option is based on the average U.S. Treasury yield curve at the balance sheet date for the expected term (weighted average of 4.88% for the nine months ended September 30, 2006) which, if increased to 6.00%, would increase the weighted average estimated fair value of stock options granted during the nine months ended September 30, 2006 by $0.26 per share, or 2.7%.

We are required to assume a dividend yield as an input to the Black-Scholes model. The dividend yield assumption is based on our history. As we have never issued dividends and as we do not anticipate paying dividends in the foreseeable future, we have utilized a dividend yield of 0.0%.

Leasehold Incentive Obligation

In conjunction with the lease agreement covering the new facility to be occupied by us, we received a tenant improvement allowance not to exceed $9.9 million. As the tenant improvements are constructed, we record both the covered tenant improvements (as fixed assets) and an offsetting incentive lease obligation on our balance sheet. Once we take occupancy of the new facility, we will record depreciation expense to depreciate the tenant improvements and record an offsetting reduction to rent expense (to amortize the leasehold incentive obligation) over the initial term of the lease, in accordance with FASB Technical Bulletin 88-1, Issues Relating to Accounting for Leases.

New Accounting Pronouncements

In June 2006, the Financial Accounting Standards Board (“FASB”) ratified EITF Issue No. 06-2, Accounting for Sabbatical Leave and Other Similar Benefits Pursuant to FASB Statement No. 43, Accounting for Compensated Absences. EITF 06-2 provides guidelines under which sabbatical leave or other similar benefits provided to an employee are considered to accumulate, as defined in FASB Statement 43. If such benefits are deemed to accumulate, then the compensation cost associated with a sabbatical or other similar benefit arrangement should be accrued over the requisite service period. The provisions of this Issue are effective for fiscal years beginning after December 15, 2006 and allow for either retrospective application or a cumulative effect adjustment to accumulated deficit approach upon adoption. We do not expect the adoption of EITF Issue No. 06-02 to have a material impact on our financial statements.

ITEM 3. QUANTITATIVE AND QUALITATIVE DISCLOSURES ABOUT MARKET RISK

Our primary exposure to market risk is interest income sensitivity, which is affected by changes in the general level of United States interest rates. Due to the nature of our short-term investments, we believe that we are not subject to any material market risk exposure. We do not have any foreign currency or other derivative financial instruments.

ITEM 4. CONTROLS AND PROCEDURES

Prior to the filing of this quarterly report on Form 10-Q, we carried out an evaluation, under the supervision and with the participation of our management, including our President and Chief Executive Officer and our Senior Vice President and Chief Financial and Business Officer, of the effectiveness of our disclosure controls and procedures (as defined in Rules 13a - 15(e) or 15d -15(e) of the Exchange Act) as of the end of the period covered by this quarterly report on Form 10-Q. Disclosure controls and procedures are designed to ensure that information required to be disclosed in our periodic reports filed or submitted under the Exchange Act is recorded, processed, summarized and reported within the time periods specified in the SEC’s rules and forms. Based upon that evaluation, our President and Chief Executive Officer and our Senior Vice President and Chief Financial and Business Officer concluded that our disclosure controls and procedures were effective as of the end of the period covered by this quarterly report on Form 10-Q.

An evaluation was also performed under the supervision and with the participation of our management, including our President and Chief Executive Officer and our Senior Vice President and Chief Financial and Business Officer, of any change in our internal control over financial reporting that occurred during our last fiscal quarter and that has materially affected, or is reasonably likely to materially affect, our internal control over financial reporting. That evaluation did not identify any change in our internal control over financial reporting that occurred during our latest fiscal quarter and that has materially affected, or is reasonably likely to materially affect, our internal control over financial reporting.

Our management, including our President and Chief Executive Officer and our Senior Vice President and Chief Financial and Business Officer, does not expect that our disclosure controls will prevent all errors or potential fraud. A control system, no matter how well conceived and operated, can provide only reasonable and not absolute assurance that the objectives of the control system are met. Further, the design of a control system must reflect the fact that there are resource constraints, and the benefits of controls must be considered relative to their cost. Because of the inherent limitations in all control systems, no evaluation of controls can provide absolute assurance that all control issues and instances of fraud, if any, within our company have been detected. These inherent limitations include the realities that judgments in decision-making can be faulty, and that breakdowns can occur because of simple error or mistake. Additionally, controls can be circumvented by the individual acts of some persons or by collusion of two or more people. The design of any system of controls also is based in part upon certain assumptions about the likelihood of future events, and there can be no assurance that any design will succeed in achieving its stated goals under all potential future conditions; over time, control may become inadequate because of changes in conditions, or the degree of compliance with policies or procedures may deteriorate. Because of the inherent limitations in a cost-effective control system, misstatements due to error or fraud may occur and not be detected.

PART II. OTHER INFORMATION

ITEM 1A. RISK FACTORS

The following sets forth risk factors associated with our business. The risk factors set forth below with an asterisk (*) next to the title contain changes to the description of the risk factors associated with our business previously disclosed in Item 1A. of our 2005 Annual Report on Form 10-K. Additional risks and uncertainties that we are unaware of may also become important factors that affect us. If any of the following risks occur, our business, financial condition or results of operations could be materially and adversely affected. In these circumstances, the market price of our common stock could decline.

Risks Related To Our Business

We are dependent on our product discovery and development collaborators for all of our revenue and we are dependent on our current and any future product discovery and development collaborators to develop and commercialize any flavors, flavor enhancers or taste modulators we may discover. *

A key element of our strategy is to commercialize our flavors, flavor enhancers and taste modulators through product discovery and development collaborations. To date, all of our revenue has been derived solely from research and development payments and milestone payments received under collaboration agreements with Ajinomoto, Cadbury Schweppes, Campbell Soup, Coca-Cola, Kraft Foods and Nestlé. Substantially all of our revenue in the foreseeable future will result from these types of payments from these collaborations, unless we successfully commercialize a product candidate through these or other collaborators and earn royalties on future sales of consumer products incorporating our flavors, flavor enhancers or taste modulators.

Our agreement, as amended, with Campbell Soup provides for research and development funding until March 2009 and gives Campbell Soup the right to terminate the agreement earlier without cause, provided that it pay a specified termination fee if it terminates the agreement prior to March 28, 2009. Our agreement with Coca-Cola provides for research and development funding until April 2008, and gives Coca-Cola the right to conclude the collaborative program earlier for any reason upon payment to us of an early conclusion fee. Our agreement with Kraft Foods provides for research and development funding until December 2008, and gives Kraft Foods the right to conclude the agreement earlier for any reason upon payment to us of a termination fee. Our initial agreement with Nestlé (as amended in April 2005) provides for research and development funding through April 2008 and gives Nestlé the right to terminate the agreement earlier without cause, provided that it pay additional specified research funding if it terminates the agreement prior to April 18, 2008. Our most recent agreement with Nestlé regarding the discovery and commercialization of novel flavor ingredients in the coffee and coffee whitener fields provides for research and development funding through January 2010 and gives Nestlé the right to terminate the agreement earlier without cause on or after January 26, 2007, provided that it pay additional specified research funding if it terminates the agreement after January 26, 2007 but prior to January 26, 2010. Our agreement with Cadbury Schweppes provides for research and development funding through July 2007, and gives Cadbury Schweppes the right to terminate the agreement earlier without cause upon 90 days’ written notice. Our initial agreement with Ajinomoto provides for research and development funding through March 2009 and gives Ajinomoto the right to terminate the agreement without cause provided that it pay additional specified research funding if it terminates the agreement prior to March 23, 2009. Our most recent agreement with Ajinomoto provides for research and development funding through October 2009 and gives Ajinomoto the right to terminate the agreement without cause provided that it pay additional specified research funding if it terminates the agreement prior to October 5, 2009. If any or all of our material agreements with our collaborators expire or are terminated, our revenue would significantly decline and if all of our agreements expire or are terminated, our revenue would be substantially eliminated, which would have a material adverse effect on our business, financial condition and results of operations. Our collaborators may not renew their agreements with us or, if they do, they may not be on terms that are as favorable to us as our current agreements.

Our current collaboration agreements provide that we will receive royalties of up to 4% on our collaborators’ sales of products containing our flavors, flavor enhancers or taste modulators. The actual royalties payable vary by agreement and depend on a number of factors including, for example, the product field, cost of goods savings, degree of flavor enhancement and sales volume of collaborator products incorporating our flavor ingredients. It is possible that our collaborators will not incorporate our flavors, flavor enhancers and taste modulators into any or all of their products within their exclusive or co-exclusive product fields.

We do not currently have a commercialized product and cannot assure you we will have a commercialized product in the foreseeable future, or at all. We will be dependent on our current and any other possible future collaborators to commercialize any flavors, flavor enhancers or taste modulators that we successfully develop and to provide the sales, marketing and distribution capabilities required for the success of our business. We have limited or no control over the amount and timing of resources that our current or any future collaborators may devote to our programs or potential products. Our collaborators may decide not to devote the necessary resources to the commercialization of our flavors, flavor enhancers or taste modulators, or may pursue a competitor’s product if our flavors, flavor enhancers or taste modulators do not have the characteristics desired by the collaborator. These characteristics include, among other things, enhancement properties, temperature stability, solubility, taste and cost. If these collaborators fail to conduct their commercialization, sales and marketing or distribution activities successfully and in a timely manner, we will earn little or no royalty revenues from our flavors, flavor enhancers and taste modulators and we will not be able to achieve our objectives or build a sustainable or profitable business.

Our present and any future product discovery and development collaboration opportunities could be harmed if:

· our existing or any future collaborators terminate their collaboration agreements with us prior to the expiration of the agreements;

· we do not achieve our research and development objectives under our collaboration agreements prior to the termination of the collaboration periods;

· we disagree with our collaborators as to the parties’ respective licensing rights to our flavors, flavor enhancers and taste modulators, methods or other intellectual property we develop;

· we are unable to manage multiple simultaneous collaborations;

· potential collaborators fail to spend their resources on research and development or commercialization of our flavors, flavor enhancers and taste modulators due to general market conditions or for any other reason; or

· consolidation in our target markets limits the number of potential collaborators.

We may not be able to negotiate additional collaboration agreements having terms satisfactory to us or at all.*

We may not be able to enter into additional product discovery and development collaborations due to the exclusive nature of our current product discovery and development collaborations. Each of our current collaboration agreements provides that we will conduct research and development on flavors, flavor enhancers and taste modulators for use within one or more defined packaged food and beverage product fields on an exclusive or co-exclusive basis for the respective collaborator during the collaborative period specified in the agreement. Because each of these agreements is exclusive or co-exclusive, we will not be able to enter into a collaboration agreement with any other food and beverage company covering the same product field during the applicable collaborative period. In addition, our collaborators’ competitors may not wish to do business with us at all due to our relationship with our collaborators. If we are unable to enter into additional product discovery and development collaborations, our ability to sustain or expand our business will be significantly diminished.

We may not be successful in developing flavors, flavor enhancers or taste modulators useful for formulation into products.*

We may not succeed in developing flavors, flavor enhancers or taste modulators with the appropriate attributes required for use in successful commercial products. Successful flavors, flavor enhancers and taste modulators require, among other things, appropriate biological activity, including the correct taste property for the product application, an acceptable safety profile, including lack of toxicity or allergenicity, and appropriate physical or chemical properties, including relative levels of stability, volatility and resistance to heat. Successful flavors, flavor enhancers and taste modulators must also be cost-efficient for our collaborators. We may not be able to develop flavors, flavor enhancers or taste modulators that meet these criteria.

If we or our collaborators are unable to obtain and maintain the GRAS determination or regulatory approval required before any flavors, flavor enhancers or taste modulators can be incorporated into products that are sold, we would be unable to commercialize our flavors, flavor enhancers and taste modulators and our business would be adversely affected.*

In March 2005, we obtained a Generally Recognized as Safe, or GRAS, determination for four of our savory flavor ingredients. Apart from these flavor ingredients, we do not have GRAS determination or regulatory approval for any other flavor ingredient at this time. In the United States, the development, sale and incorporation of our flavors, flavor enhancers or taste modulators into products are subject to regulation by the Food and Drug Administration, or FDA, and in some instances other government bodies. Obtaining and maintaining a GRAS determination or regulatory approval can be costly and take many years.

Depending on the amount or intended use of a particular flavor, flavor enhancer or taste modulator added to a product and the number of product categories in which the flavor, flavor enhancer or taste modulator will be incorporated, specific safety assessment protocols and regulatory processes must be satisfied before we or our collaborators can commercially market and sell products containing any flavors, flavor enhancers or taste modulators that we may discover. A key element of our strategy is to develop flavors, flavor enhancers and taste modulators that may be subject to review under the Flavor and Extract Manufacturers Association, or FEMA, GRAS process. In our experience with the savory program, safety studies, preparation and FEMA GRAS review took approximately 10 months and cost less than $1 million. This experience may not be representative of the timing and cost for future programs. This approach is less expensive than the alternative of filing a food additive petition with the FDA, approval of which can take eight years or more. The FEMA GRAS process may take longer than 10 months and cost more than $1 million depending on the properties of the flavor, flavor enhancer or taste modulator, and if additional safety studies are requested by the FEMA Expert Panel or are necessary to explain unexpected safety study findings. There is a risk that one or more of our product candidates may not qualify for a FEMA GRAS determination. This may occur for a variety of reasons, including the flavor, flavor enhancer or taste modulator’s intended use, the amount of the flavor, flavor enhancer or taste modulator intended to be added to packaged foods and beverages, the number of product categories in which the flavor, flavor enhancer or taste modulator will be incorporated, whether the flavor, flavor enhancer or taste modulator imparts sweetness, the safety profile of the flavor, flavor enhancer or taste modulator and the FEMA Expert Panel’s interpretation of the safety data. Even if we obtain a GRAS determination with respect to a flavor, flavor enhancer or taste modulator, the FDA has the ability to challenge such determination, which could materially adversely affect our ability to market products on schedule or at all. In the event that a particular flavor, flavor enhancer or taste modulator does not qualify for FEMA GRAS determination, we could be required to pursue a lengthy FDA approval process or dedicate our development efforts to alternative compounds, which would further delay commercialization. In addition, laws, regulations or FDA practice governing the regulatory approval process, the availability of the GRAS determination process or the manufacture or labeling of such products, may change in a manner that could adversely affect our ability to commercialize products on schedule or at all.

Sales of our flavors, flavor enhancers or taste modulators outside of the United States will be subject to foreign regulatory requirements. In most cases, whether or not a GRAS determination or FDA approval has been obtained, approval of a product by the comparable regulatory authorities of foreign countries must still be obtained prior to manufacturing or marketing the product in those countries. A GRAS determination or FDA approval in the United States or in any other jurisdiction does not ensure approval in other jurisdictions because the requirements from jurisdiction to jurisdiction may vary widely. Obtaining foreign approvals could result in significant delays, difficulties and costs for us and require additional safety studies and additional expenses. If we fail to comply with these regulatory requirements or to obtain and maintain required approvals, our ability to generate revenue will be diminished.

We and our collaborators may not be successful in overcoming these regulatory hurdles, which could result in product launch delays, unanticipated expenses, termination of collaborations, and flavors, flavor enhancers and taste modulators not being approved for incorporation into consumer products. These consequences would have a material adverse effect on our business financial condition and results of operations.

Even if we or our collaborators receive a GRAS determination or regulatory approval and incorporate our flavors, flavor enhancers or taste modulators into products, those products may never be commercially successful.

Even if we discover and develop flavors, flavor enhancers and taste modulators that obtain the necessary GRAS determination or regulatory approval, our success depends to a significant degree upon the commercial success of packaged food and beverage products incorporating those flavors, flavor enhancers or taste modulators. If these products fail to achieve or subsequently maintain market acceptance or commercial viability, our business would be significantly harmed because our royalty revenue is dependent upon consumer sales of these products. In addition, we could be unable to maintain our existing collaborations or attract new product discovery and development collaborators. Many factors may affect the market acceptance and commercial success of any potential products incorporating flavors, flavor enhancers or taste modulators that we may discover, including:

· health concerns, whether actual or perceived, or unfavorable publicity regarding our flavors, flavor enhancers and taste modulators or those of our competitors;

· the timing of market entry as compared to competitive products;

· the rate of adoption of products by our collaborators and other companies in the flavor industry; and

· any product labeling that may be required by the FDA or other United States or foreign regulatory agencies for products incorporating our flavors, flavor enhancers and taste modulators.

We have a history of operating losses and we may not achieve or maintain profitability. *

We have not been profitable and have generated substantial operating losses since we were incorporated in September 1998. We incurred net losses of approximately $17.8 million for the nine months ended September 30, 2006. As of September 30, 2006, we had an accumulated deficit of approximately $122.0 million. We expect to incur additional losses for at least the next two years. The extent of our future losses will depend, in part, on the rate of increase in our operating expenses and the rate of growth, if any, in our revenue from our six existing and any future product discovery and development collaborations as well as from other sources that may become available to us in the future and on the level of our expenses. To date, our revenue has come solely from research and development funding, upfront fees, cost reimbursement and milestone payments under our product discovery and development collaboration agreements with Ajinomoto, Cadbury Schweppes, Campbell Soup, Coca-Cola, Kraft Foods and Nestlé. In order for us to generate royalty revenue and become profitable, we must retain our existing product discovery and development collaborations and our collaborators must commercialize products incorporating one or more of our flavors, flavor enhancers or taste modulators, from which we can derive royalty revenues. Our ability to generate royalty revenue is uncertain and will depend upon our ability to meet particular research, development and commercialization objectives.

We expect that our results of operations will fluctuate from period to period, and this fluctuation could cause our stock price to decline. *

Our operating results have fluctuated in the past and are likely to vary significantly in the future based upon a number of factors, many of which we have little or no control over. We operate in a highly dynamic industry and future results could be subject to significant fluctuations. These fluctuations could cause us to fail to meet or exceed financial expectations of securities analysts or investors, which could cause our stock price to decline rapidly and significantly. Revenue and expenses in future periods may be greater or less than revenue and expenses in the immediately preceding period or in the comparable period of the prior year. Therefore, period-to-period comparisons of our operating results are not necessarily a good indication of our future performance. Some of the factors that could cause our operating results to fluctuate include:

· termination of any of our product discovery and development collaboration agreements;

· our ability to discover and develop flavors, flavor enhancers and taste modulators or the ability of our product discovery and development collaborators to incorporate them into packaged food and beverage products;

· our receipt of milestone payments in any particular period;

· the ability and willingness of collaborators to commercialize products incorporating our flavors, flavor enhancers and taste modulators on expected timelines, or at all;

· our ability to enter into new product discovery and development collaborations and technology collaborations or to extend the terms of our existing collaboration agreements and our payment obligations, expected revenue and other terms of any other agreements of this type;

· our ability, or our collaborators’ ability, to successfully satisfy all pertinent regulatory requirements;

· the demand for our collaborators’ products containing our flavors, flavor enhancers and taste modulators; and

· general and industry specific economic conditions, which may affect our collaborators’ research and development expenditures.

Changes in financial accounting standards related to stock-based compensation expenses are expected to have a significant effect on our reported results. *

On January 1, 2006 we adopted Statement of Financial Accounting Standards, or SFAS, No. 123R, Share-Based Payment, which requires that we record compensation expense in the statement of operations for stock-based payments, such as employee stock options, using the fair value method. The adoption of the new standard is expected to continue to have a significant effect on our reported earnings, although it will not affect our cash flows, and could adversely impact our ability to provide accurate guidance on our projected future financial results due to the variability of the factors used to establish the value of stock options. If factors change and we employ different assumptions or different valuation methods in the application of SFAS 123R in future periods, the compensation expense that we record under SFAS 123R may differ significantly from what we have recorded in the current period, which could negatively affect our stock price and our stock price volatility.

Compliance with regulation of corporate governance and public disclosure may result in additional expenses. *

Laws, regulations and standards relating to corporate governance and public disclosure, including the Sarbanes-Oxley Act of 2002, SEC regulations and Nasdaq National Market rules, are costly to comply with. Our efforts to comply with these laws, regulations and standards, as they become applicable to us, have resulted in, and are likely to continue to result in, general and administrative expense and management time related to compliance activities. In particular, our efforts to comply with Section 404 of the Sarbanes-Oxley Act of 2002 and the related regulations regarding our required assessment of our internal controls over financial reporting and our external auditors’ audit of that assessment requires the commitment of significant financial and managerial resources. If our efforts to comply with laws, regulations and standards differ from the activities intended by regulatory or governing bodies, our reputation may be harmed and we might be subject to sanctions or investigation by regulatory authorities, such as the Securities and Exchange Commission. Any such action could adversely affect our financial results and the market price of our common stock.

We may need to obtain additional capital to fund our operations.

If we are unable to successfully commercialize our flavors, flavor enhancers and taste modulators, we may need to obtain additional capital or change our strategy to continue our operations. In addition, our business and operations may change in a manner that would consume available resources at a greater rate than anticipated. In such event, we may need to raise substantial additional capital to, among other things:

· fund new research, discovery or development programs;

· advance additional product candidates into and through the regulatory approval process; and

· acquire rights to products or product candidates, technologies or businesses.

If we require additional capital to continue our operations, we cannot assure you that additional financing will be available on terms acceptable to us, or at all. If adequate funds are not available or are not available on acceptable terms, our ability to fund our operations, take advantage of opportunities, identify and develop flavors, flavor enhancers and taste modulators, develop technologies or otherwise respond to competitive pressures could be significantly limited. In addition, if financing is not available, we may need to alter our strategy or cease operations. In addition, issuances of debt or additional equity could impact the rights of the holders of our common stock, may dilute our stockholders’ ownership and may impose restrictions on our operations. These restrictions could include limitations on additional borrowing, specific restrictions on the use of our assets as well as prohibitions on our ability to create liens, pay dividends, redeem our stock or make investments.

If we lose our key personnel or are unable to attract and retain qualified personnel, it could adversely affect our business.*

Our success depends to a significant degree upon the continued contributions of our executive officers, management and scientific staff. If we lose the services of one or more of these people and, in particular, Kent Snyder, our President and Chief Executive Officer, or Mark Zoller, Ph.D., our Executive Vice President of Discovery & Development and Chief Scientific Officer, the relationships we have with our collaborators would likely be negatively impacted and we may be delayed or unable to develop new product candidates, commercialize our existing product candidates or achieve our other business objectives, any of which could cause our stock price to decline. We have entered into employment letter agreements with the following executive officers: Kent Snyder, Mark Zoller, Ph.D., Harry Leonhardt, Esq., our Senior Vice President, General Counsel and Corporate Secretary, John Poyhonen, our Senior Vice President, Chief Financial and Business Officer, Nigel R.A. Beeley, Ph.D., our Vice President, Discovery and Sharon Wicker, our Senior Vice President, Commercial Development and Chief Strategy Officer. All of our employees are at-will employees, which means that either we or the employee may terminate their employment at any time. We currently have no key person insurance.

In addition, our discovery and development programs depend on our ability to attract and retain highly skilled scientists, including molecular biologists, biochemists, chemists and engineers. We may not be able to attract or retain qualified employees in the future due to the intense competition for qualified personnel among technology-based businesses, particularly in the San Diego area. We also face competition from universities and public and private research institutions in recruiting and retaining highly qualified scientific and management personnel. 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 current or any future product discovery and development collaborators in a timely fashion or to support our independent discovery and development programs.

We may encounter difficulties managing our growth, which could adversely affect our business. *

Our strategy includes entering into and working on simultaneous flavor and flavor enhancer discovery and development programs across multiple markets. We increased the number of our full-time employees from seven on December 31, 1999 to 111 on September 30, 2006 and we expect to continue to grow to meet our strategic objectives. If our growth continues, it will continue to place a strain on us, our management and our resources. 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. We may not be able to successfully implement these tasks on a larger scale and, accordingly, we may not achieve our research, development and commercialization goals. If we fail to improve our operational, financial and management information systems, or fail to effectively monitor or manage our new and future employees or our growth, our business would suffer significantly. In addition, no assurance can be made that we will be able to secure adequate facilities to house our staff, conduct our research or achieve our business objectives.

We will rely on third parties to manufacture our flavors, flavor enhancers and taste modulators on a commercial scale.

We do not have experience in manufacturing, nor do we have the resources or facilities to manufacture, flavors, flavor enhancers and taste modulators on a commercial scale. Therefore, the commercialization of our flavors, flavor enhancers and taste modulators will depend in part on our or our collaborators’ ability to contract with third-party manufacturers of our flavors, flavor enhancers and taste modulators on a large scale, at a competitive cost, with the specified quality and in accordance with relevant food and beverage regulatory requirements. Any such third-party manufacturers may encounter manufacturing difficulties at any time that could result in delays in the commercialization of potential flavors, flavor enhancers and taste modulators. Our inability to find capable third-party manufacturers or to enter into agreements on acceptable terms with third-party manufacturers could delay commercialization of any products we may develop and may harm our relationships with our existing and any future product discovery and development collaborators and our customers. Moreover, if we are required to change from one third-party manufacturer to another for any reason, the commercialization of our products may be delayed further. In addition, if third-party manufacturers fail to comply with the FDA’s good manufacturing practice regulations or similar regulations in other countries, then we may be subject to adverse regulatory action including product recalls, warning letters and withdrawal of our products, or our collaborators’ or customers’ products, from the market.

Further, because our flavors, flavor enhancers and taste modulators are regulated as food products under the Federal Food, Drug and Cosmetic Act, we and the third parties with which we collaborate or contract to manufacture, process, pack, import or otherwise handle our products or our product ingredients, may be required to comply with certain registration, prior notice submission, recordkeeping and other regulatory requirements. Failure of any party in the chain of distribution to comply with any applicable requirements under the Federal Food, Drug and Cosmetic Act or the FDA’s implementing regulations, or similar regulations in other countries, may adversely affect the manufacture and/or distribution of our products in commerce.

If we acquire products, technologies or other businesses, we will incur a variety of costs, may have integration difficulties and may experience numerous other risks that could adversely affect our business.

If appropriate opportunities become available, we may consider acquiring businesses, technologies or products that we believe are a strategic fit with our business. We currently have no commitments or agreements with respect to, and are not actively seeking, any material acquisitions. We have limited experience in identifying acquisition targets, successfully acquiring them and integrating them into our current infrastructure. We may not be able to successfully integrate any businesses, 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 be funded by issuances of additional debt or equity, which could impact your rights as a holder of our common stock and may dilute your ownership percentage. Any of the foregoing could have a significant adverse effect on our business, financial condition and results of operations.

Risks Related To Our Industry

Our ability to compete in the flavor and flavor enhancer market may decline if we do not adequately protect our proprietary technologies.

Our success depends in part on our ability to obtain and maintain intellectual property that protects our technologies and flavors, flavor enhancers and taste modulators. Patent positions may be highly uncertain and may involve complex legal and factual questions, including the ability to establish patentability of sequences relating to taste receptors, proteins, chemical synthesis techniques, compounds and methods for using them to modulate taste for which we seek patent protection. No consistent standard regarding the allowability or enforceability of claims in many of our pending patent applications has emerged to date. As a result, we cannot predict the breadth of claims that will ultimately be allowed in our patent applications, if any, including those we have in-licensed or the extent to which we may enforce these claims against our competitors. The degree of future protection for our proprietary rights is therefore highly uncertain and we cannot assure you that:

· we were the first to file patent applications or to invent the subject matter claimed in patent applications relating to the technologies upon which we rely;

· others will not independently develop similar or alternative technologies or duplicate any of our technologies;

· others did not publicly disclose our claimed technology before we conceived the subject matter included in any of our patent applications;

· any of our patent applications will result in issued patents;

· any of our patent applications will not result in interferences or disputes with third parties regarding priority of invention;

· any patents that have issued or may be issued to us, our collaborators or our licensors will provide a basis for commercially viable products or will provide us with any competitive advantages or will not be challenged by third parties;

· we will develop additional proprietary technologies that are patentable;

· the patents of others will not have an adverse effect on our ability to do business; or

· new proprietary technologies from third parties, including existing licensors, will be available for licensing to us on reasonable commercial terms, if at all.

In addition, patent law outside the United States is uncertain and in many countries intellectual property laws are undergoing review and revision. The laws of some countries do not protect intellectual property rights to the same extent as domestic laws. It may be necessary or useful for us to participate in opposition proceedings to determine the validity of our competitors’ patents or to defend the validity of any of our or our licensor’s future patents, which could result in substantial costs and would divert our efforts and attention from other aspects of our business.

Technologies licensed to us by others, or in-licensed technologies, are important to our business. In particular, we depend on high-throughput screening technologies that we licensed from Aurora Biosciences, technology related to certain taste receptor sequences that we license from the University of California and others and technology related to compound libraries that we license from third parties. In addition, we may in the future acquire rights to additional technologies by licensing such rights from existing licensors or from third parties. Such in-licenses may be costly. Also, we generally do not control the patent prosecution, maintenance or enforcement of in-licensed technologies. Accordingly, we are unable to exercise the same degree of control over this intellectual property as we do over our internally developed technologies. Moreover, some of our academic institution licensors, collaborators and scientific advisors have rights to publish data and information to which we have rights. If we cannot maintain the confidentiality of our technologies and other confidential information in connection with our collaborations, our ability to protect our proprietary information or obtain patent protection in the future may be impaired, which could have a significant adverse effect on our business, financial condition and results of operations.

Many of the patent applications we and our licensors have filed have not yet been substantively examined and may not result in patents being issued.

Many of the patent applications filed by us and our licensors were filed recently with the United States Patent and Trademark Office and most have not been substantively examined and may not result in patents being issued. Some of these patent applications claim sequences that were identified from different publicly available sequence information sources such as the High-Throughput Genomic Sequences division of GenBank. It is difficult to predict whether any of our or our licensors’ applications will ultimately be found to be patentable or, if so, to predict the scope of any allowed claims. In

addition, the disclosure in our or our licensors’ patent applications, particularly in respect of the utility of our claimed inventions, may not be sufficient to meet the statutory requirements for patentability in all cases. As a result, it is difficult to predict whether any of our or our licensors’ applications will be allowed, or, if so, to predict the scope of any allowed claims or the enforceability of the patents. Even if enforceable, others may be able to design around any patents or develop similar technologies that are not within the scope of such patents. Our and our licensors’ patent applications may not issue as patents that will provide us with any protection or competitive advantage.

Disputes concerning the infringement or misappropriation of our proprietary rights or the proprietary rights of others could be time consuming and extremely costly and could delay our research and development efforts.

Our commercial success, if any, will be significantly harmed if we infringe the patent rights of third parties or if we breach any license or other agreements that we have entered into with regard to our technology or business.

We are aware of other companies and academic institutions that have been performing research in the areas of taste modulation and flavors, flavor enhancers and taste modulators. In particular, other companies and academic institutions have announced that they have conducted taste-receptor research and have published data on taste receptor sequence information and taste receptors or filed patent applications or obtained patent protection on taste modulation or taste receptors and their uses, including Linguagen Corp., Mount Sinai School of Medicine, The Scripps Research Institute, the University of California, Monell Chemical Senses Corp., Pfizer, Inc., Virginia Commonwealth University and the German Institute of Human Nutrition. To the extent any of these companies or academic institutions currently have, or obtain in the future, broad patent claims, such patents could block our ability to use various aspects of our discovery and development process and might prevent us from developing or commercializing newly discovered flavors, flavor enhancers and taste modulators or otherwise conducting our business. The University of California, for example, claims certain patent rights relating to the coexpression of T1R receptors that may not have been licensed to us. While our technology is focused on the use of human T1R receptors, we cannot assure you that it does not infringe such patent rights. In such event, if we are not able to amend our license with the University of California to include such patent rights and our technology is found to interfere with or infringe such patent rights, our business, financial condition and results of operations could suffer a significant adverse effect. In addition, it is possible that some of the flavors, flavor enhancers or taste modulators that are discovered using our technology may not be patentable or may be covered by intellectual property of third parties.

We are not currently a party to any litigation, interference, opposition, protest, reexamination, reissue or any other potentially adverse governmental, ex parte or inter-party proceeding with regard to our patent or trademark positions. However, the life sciences and other technology industries are characterized by extensive litigation regarding patents and other intellectual property rights. Many life sciences and other technology companies have employed intellectual property litigation as a way to gain a competitive advantage. If we become involved in litigation, interference proceedings, oppositions, reexamination, protest or other potentially adverse intellectual property proceedings as a result of alleged infringement by us of the rights of others or as a result of priority of invention disputes with third parties, we might have to spend significant amounts of money, time and effort defending our position and we may not be successful. In addition, any claims relating to the infringement of third-party proprietary rights or proprietary determinations, even if not meritorious, could result in costly litigation, lengthy governmental proceedings, divert management’s attention and resources, or require us to enter into royalty or license agreements that are not advantageous to us.

Should any person have filed 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 could result in substantial cost to us even if the outcome is favorable. Even if successful on priority grounds, an interference action may result in loss of claims based on patentability grounds raised in the interference action. Litigation, interference proceedings or other proceedings could divert management’s time and efforts. Even unsuccessful claims could result in significant legal fees and other expenses, diversion of management’s time and disruption in our business. Uncertainties resulting from initiation and continuation of any patent proceeding or related litigation could harm our ability to compete and could have a significant adverse effect on our business, financial condition and results of operations.

An adverse ruling arising out of any intellectual property dispute, including an adverse decision as to the priority of our inventions, could undercut or invalidate our intellectual property position. An adverse ruling could also subject us to significant liability for damages, including possible treble damages, prevent us from using technologies or developing products, or require us to negotiate licenses to disputed rights from third parties. Although patent and intellectual property disputes in the technology area are often settled through licensing or similar arrangements, costs associated with these arrangements may be substantial and could include license fees and ongoing royalties. Furthermore, necessary licenses may not be available to us on satisfactory terms, if at all. Failure to obtain a license in such a case could have a significant adverse effect on our business, financial condition and results of operations.

If we are unable to protect our trade secrets and other proprietary information, we could lose any competitive advantage we may have, which could adversely affect our business.

We rely in part on trade secret protection for our confidential and proprietary information, know how and processes. Our policy is to execute proprietary information and invention agreements with our employees and consultants upon the commencement of an employment or consulting relationship. 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 be disclosed to third parties. These agreements also generally provide that inventions conceived by the individual in the course of their employment shall be our exclusive property. There can be no assurance that we will be able to effectively enforce these agreements or that proprietary information is our exclusive property. There can be no assurance that the subject proprietary information will not be disclosed, that others will not independently develop substantially equivalent proprietary information and techniques or otherwise gain access to our trade secrets or that we can meaningfully protect 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.

Many potential competitors, including those who have greater resources and experience than we do, may develop products or technologies that make ours obsolete or noncompetitive.

The life sciences and other technology industries are characterized by rapid technological change, and the area of sensory or taste receptor research is a rapidly evolving field. Our future success will depend on our ability to maintain a competitive position with respect to technological advances. Technological developments by others may result in our flavors, flavor enhancers or taste modulators and technologies becoming obsolete.

In particular, we face substantial competition from companies pursuing the commercialization of products and services relevant to taste using more traditional methods for the discovery of flavors, flavor enhancers and taste modulators, or for the reduction of salt, sugar, MSG or bitter taste. These competitors include leading flavor companies, such as International Flavors & Fragrances Inc., Givaudan SA, Symrise, Quest International and Firmenich. We currently compete and will continue to compete in the future with these companies in collaborating with and selling flavor products and technologies to manufacturers of packaged food and beverage products. Many of these companies have substantially greater capital resources, research and development resources and experience, manufacturing capabilities, regulatory expertise, sales and marketing resources, established relationships with consumer products companies and production facilities.

Savory flavor enhancers, particularly inosine monophosphate, or IMP, are commercially available, and we will compete with the companies that produce these flavors. IMP is widely available and is a generally accepted food additive by the packaged food and beverage industry. As a result, our existing and future collaborators may choose to incorporate IMP or similar savory flavor enhancers into their packaged food and beverage products instead of our savory flavors, flavor enhancers and taste modulators. In addition, we may compete with bitter masking or bitter blocking compounds, such as adenosine 5’ monophosphate, or AMP.

We may in the future face competition from life sciences and other technology companies and other commercial enterprises. These entities engage as we do in biotechnology, biology or chemistry and could apply this technology to the discovery and development of flavors, flavor enhancers and taste modulators. We are aware of one other company, Linguagen Corp., a privately-held company that we believe is involved in research on sweetness potentiators, salt substitutes and bitter blockers, specifically AMP, and has announced research and development collaborations with several companies. We cannot guarantee that products developed as a result of our competitors’ existing or future collaborations will not compete with our flavors, flavor enhancers and taste modulators.

Universities and public and private research institutions are also potential competitors. While these organizations primarily have educational objectives, they may develop proprietary technologies related to the sense of taste or secure patent protection that we may need for the development of our technologies and products. We may attempt to license these proprietary technologies, but these licenses may not be available to us on acceptable terms, if at all.

Our competitors, either alone or with their collaborative partners, may succeed in developing technologies or discovering flavors, flavor enhancers or taste modulators that are more effective, safer, more affordable or more easily commercialized than ours, and our competitors may obtain intellectual property protection or commercialize products sooner than we do. Developments by others may render our product candidates or our technologies obsolete. In addition, our current

product discovery and development collaborators are not prohibited from entering into research and development collaboration agreements with third parties in any product field. Our failure to compete effectively would have a significant adverse effect on our business, financial condition and results of operations.

We may be sued for product liability, which could adversely affect our business.

Because our business strategy involves the development and sale by our collaborators of commercial products incorporating our flavors, flavor enhancers and taste modulators, we may be sued for product liability. We may be held liable if any product we develop and commercialize, or any product our collaborators commercialize that incorporates any of our flavors, flavor enhancers or taste modulators, causes injury or is found otherwise unsuitable during product testing, manufacturing, marketing, sale or consumer use. In addition, the safety studies we must perform and the FEMA GRAS determination we must obtain prior to incorporating our flavors, flavor enhancers and taste modulators into a commercial product will not protect us from any such liability.

If we and our collaborators commence sale of commercial products we will need to obtain product liability insurance, and this 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 developed by us or our product discovery and development collaborators. We may be obligated to indemnify our product discovery and development collaborators for product liability or other losses they incur as a result of our flavors, flavor enhancers and taste modulators. Any indemnification we receive from such collaborators for product liability that does not arise from our flavors, flavor enhancers and taste modulators may not be sufficient to satisfy our liability to injured parties. If we are sued for any injury caused by our flavors, flavor enhancers and taste modulators or products incorporating our flavors, flavor enhancers and taste modulators, our liability could exceed our total assets.

We use hazardous materials. Any claims relating to improper handling, storage or disposal of these materials could be time consuming and costly.*

Our discovery and development process requires our employees to routinely handle hazardous chemical, radioactive and biological materials. Our operations also produce hazardous waste products. Federal, state and local laws and regulations govern the use, manufacture, storage, handling and disposal of these materials. As a result of the increase in size of our operations, we were recently re-classified from a small quantity to a large quantity generator of hazardous waste. This reclassification may result in increased scrutiny of our operations by the Environmental Protection Agency. Compliance with applicable environmental laws and regulations may be expensive, and current or future environmental regulations may impair our discovery and development efforts.

In addition, we cannot entirely eliminate the risk of accidental contamination or discharge and any resultant injury from these materials. Our insurance policies have limited coverage for damages or cleanup costs related to hazardous waste disposal or contamination. We may be forced to curtail operations or be sued for any injury or contamination that results from our use or the use by others of these materials, and our liability may exceed our total assets.

Risks Related To Our Common Stock

The price of our common stock is volatile.

The market prices for securities of biotechnology companies historically have been highly volatile, and the market has from time to time experienced significant price and volume fluctuations that are unrelated to the operating performance of particular companies. Since our initial public offering in June 2004, the price of our common stock has ranged from approximately $5 per share to approximately $23 per share. The market price of our common stock may fluctuate in response to many factors, including:

· developments related to the FEMA GRAS determination and international regulatory approval of our products;

· developments concerning our collaborative agreements;

· announcements of technological innovations by us or others;

· developments in patent or other proprietary rights;

· results of safety evaluation of our flavors, flavor enhancers and taste modulators;

· results of consumer acceptance testing of our flavors, flavor enhancers and taste modulators by our collaborators;

· delays in commercialization of our flavors, flavor enhancers and taste modulators;

· future sales of our common stock by existing stockholders;

· comments by securities analysts;

· general market conditions;

· fluctuations in our operating results;

· government regulation;

· failure of any of our flavors, flavor enhancers or taste modulators, if approved, to achieve commercial success; and

· public concern as to the safety of our flavors, flavor enhancers, and taste modulators.

Anti-takeover provisions in our charter documents and under Delaware law may make an acquisition of us more complicated and the removal and replacement of our directors and management more difficult.

Provisions of our amended and restated certificate of incorporation and bylaws, as well as provisions of Delaware law, could make it more difficult for a third party to acquire us, even if doing so would benefit our stockholders. These provisions may also make it difficult for stockholders to remove and replace our board of directors and management. These provisions:

· authorize the issuance of “blank check” preferred stock by our board of directors, without stockholder approval, which could increase the number of outstanding shares and prevent or delay a takeover attempt;

· limit who may call a special meeting of stockholders;

· prohibit stockholder action by written consent, thereby requiring all stockholder actions to be taken at a meeting of our stockholders; and

· establish advance notice requirements for nominations for election to the board of directors or for proposing matters that can be acted upon at stockholder meetings.

In addition, the requirements of Section 203 of the Delaware General Corporation Law may discourage, delay or prevent a third party from acquiring us.

Our shareholder rights plan may hinder or prevent change of control transactions.

Our shareholder rights plans may discourage transactions involving an actual or potential change in our ownership. In addition, our board of directors may issue shares of preferred stock without any further action by you. Such issuances may have the effect of delaying or preventing a change in our ownership. If changes in our ownership are discouraged, delayed or prevented, it would be more difficult for our current board of directors to be removed and replaced, even if you and other stockholders believe such actions are in the best interests of us and our stockholders.

We have never paid cash dividends on our capital stock and we do not anticipate paying dividends in the foreseeable future.

We have paid no cash dividends on any of our classes of capital stock to date, and we currently intend to retain our future earnings, if any, to fund the development and growth of our business. In addition, the terms of any future debt or credit facility may preclude us from paying any dividends. As a result, capital appreciation, if any, of our common stock will be your sole source of potential gain for the foreseeable future.

ITEM 2. UNREGISTERED SALES OF EQUITY SECURITIES AND USE OF PROCEEDS

Our initial public offering, referred to as the Offering, of our common stock, par value $0.001, was effected through a Registration Statement on Form S-1 (File No. 333-113998) that was declared effective by the SEC on June 21, 2004. The Registration Statement covered the offer and sale of up to 6,900,000 shares of our common stock for an aggregate offering price of $41.4 million. The Offering commenced on June 22, 2004. On June 25, 2004, 6,000,000 shares of common stock were sold for an aggregate offering price of $36.0 million. On July 23, 2004, 450,000 shares of our common stock were sold for an aggregate offering price of $2.7 million upon the exercise of the underwriters’ over-allotment option. The Offering terminated following the sale of all of the foregoing securities and the expiration of the underwriters’ over-allotment option. The Offering resulted in aggregate proceeds to us of approximately $34.3 million, net of underwriting discounts and commissions of approximately $2.7 million and offering expenses of approximately $1.7 million, through a syndicate of underwriters managed by Citigroup Global Markets Inc., Deutsche Bank Securities Inc., Needham & Company, Inc. and First Albany Capital Inc.

No offering expenses were paid directly or indirectly to any of our directors or officers (or their associates) or person owning ten percent or more of any class of our equity securities or to any other affiliates. All offering expenses were paid directly to others.

As of September 30, 2006, we estimate that we had used approximately $6.3 million for the purchase of equipment and approximately $25.5 million for working capital expenditures. The remainder of the proceeds has been invested into short-term securities and cash equivalents.

The foregoing payments were direct payments made to third parties who were not our directors or officers (or their associates), persons owning ten percent or more of any class of our equity securities or any other affiliate, except that the proceeds used for working capital included regular compensation for officers and directors. The use of proceeds does not represent a material change from the use of proceeds described in the prospectus we filed pursuant to Rule 424(b) of the Securities Act with the SEC on June 22, 2004.

On November 9, 2005, we completed a public offering of 4,049,295 shares of common stock for proceeds of $57.3 million, net of underwriting discounts, commissions and offering expenses. The offering was made under a shelf registration statement and included the exercise by the underwriters of an over-allotment option of 528,169 shares of common stock. No proceeds from this offering had been used as of September 30, 2006.
