NOTES TO FINANCIAL STATEMENTS

(Unaudited)

1. Basis of Presentation

The financial statements included herein have been prepared by Repligen Corporation (the “Company”, “Repligen” or “we”) in accordance with accounting principles generally accepted in the United States and pursuant to the rules and regulations of the Securities and Exchange Commission (“SEC”), for quarterly reports on Form 10-Q and Article 10 of Regulation S-X and do not include all of the information and footnote disclosures required by accounting principles generally accepted in the United States. These financial statements should be read in conjunction with the audited financial statements and accompanying notes thereto included in our annual report on Form 10-K for the year ended March 31, 2008.

In the opinion of management, the accompanying unaudited financial statements include all adjustments, consisting of only normal, recurring adjustments necessary for a fair presentation of the financial position, results of operations and cash flows. The results of operations for the interim periods presented are not necessarily indicative of results to be expected for the entire year.

The preparation of financial statements in conformity with accounting principles generally accepted in the United States 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.

2. Revenue Recognition

The Company applies Staff Accounting Bulletin No. 104, “Revenue Recognition,” (“SAB 104”), and Emerging Issues Task Force 00-21, Revenue Arrangements with Multiple Deliverables (“EITF 00-21”) to all its revenue arrangements.

The Company generates product revenues from the sale of Protein A products to customers in the pharmaceutical and process chromatography industries. Prior to the end of the second quarter in fiscal year 2009 and the termination of our marketing agreement with ChiRhoClin, Inc. (“ChiRhoClin”), the Company also generated product revenue from the sale of SecreFlo^® to hospital-based gastroenterologists. In accordance with SAB 104, the Company recognizes revenue related to product sales upon delivery of the product to the customer as long as there is persuasive evidence of an arrangement, the sales price is fixed or determinable and collection of the related receivable is reasonably assured. Determination of whether these criteria have been met are based on management’s judgments primarily regarding the fixed nature of the fee charged for product delivered, and the collectability of those fees. The Company has a few longstanding customers who comprise the majority of product revenue and have excellent payment history. The Company has had no significant write-offs of uncollectible invoices in the periods presented. Should changes in conditions cause management to determine that these criteria are not met for certain future transactions, revenue recognized for any reporting period could be adversely affected.

At the time of sale, the Company evaluates the need to accrue for warranty and sales returns. The supply agreements the Company has with its customers and related purchase orders identify the terms and conditions of each sale and the price of the goods ordered. Due to the nature of the sales arrangements, inventory produced for sale is tested for quality specifications prior to shipment. Since the product is manufactured to order and in compliance with required specifications prior to shipment, the likelihood of sales return, warranty or other issues is largely diminished. Sales returns and warranty issues are infrequent and have had nominal impact on the Company’s financial statements historically. Should changes in conditions cause management to determine that warranty, returns or other sale-related reserves are necessary for certain future transactions, revenue recognized for any reporting period could be adversely affected.

The Company recognizes royalty revenue in the period earned. Royalty revenue for the period was predominantly generated pursuant to an agreement with Bristol-Myers Squibb Company (“Bristol”) entered into on April 7, 2008 (see Note 14). The Company also recognized $0.3 million from ChiRhoClin for their sales of secretin during the quarter. Bristol royalties are based on Bristol’s net U.S. sales of Orencia^® through 2013, and are payable quarterly. During the nine months ended December 31, 2008, the Company recognized $11.6 million in Bristol royalties, which included an initial $5.0 million payment, $1.3 million for sales of Orencia^® from January 1, 2008 to March 31, 2008, and $5.3 million for sales of Orencia^® from April 1, 2008 to December 31, 2008. Bristol began selling Orencia^® in February 2006. The initial $5.0 million payment was considered payment for sales from February 2006 to December 31, 2007 and is consistent with the royalty rate applied to sales of Orencia^® after December 31, 2007. This initial payment is non-refundable, there are no future delivery obligations on the part of the Company, and our rights to this revenue are not dependent on future sales of Orencia^®, if any. Therefore, the Company has recognized this initial payment as royalty revenue upon receipt during the first quarter of fiscal 2009.

Research revenue, which is included in Royalty and other revenue on our statements of operations, is recognized on a cost plus fixed-fee basis when the expense has been incurred and services have been performed, or for certain contracts, upon the delivery of agreed

upon milestones. Determination of which costs incurred qualify for reimbursement under the terms of the contractual agreement and the timing of when such costs were incurred involves the judgment of management. The Company believes its calculations are consistent with the agreed-upon terms as stated in the arrangement. However, should the estimated calculations change or be challenged by our research partners, research revenue may be adjusted in subsequent periods. The calculations have not historically changed or been challenged and the Company does not anticipate any subsequent change in its revenue related to sponsored research and development projects. During the nine-month period ended December 31, 2008, the Company recognized $0.7 million in research revenue. During the nine-month period ended December 31, 2007, the Company recognized $0.4 million in research revenue.

There have been no material changes to the Company’s initial estimates related to revenue recognition in any periods presented in the accompanying financial statements.

3. Earnings (Loss) Per Share

We follow the provisions of Statement of Financial Accounting Standard or SFAS No. 128, “Earnings Per Share,” (“SFAS 128”). Basic earnings per share for the three and nine-month periods ended December 31, 2008 and 2007 were computed on the basis of the weighted average number of shares of common stock outstanding during the period. Diluted earnings per share is computed on the basis of the weighted average number of shares of common stock plus the effect of dilutive potential common shares outstanding during the period using the treasury stock method in accordance with SFAS 128. Dilutive potential common shares include outstanding stock options.

Basic and diluted weighted average shares outstanding were as follows:


	Three months ended December 31,		Nine months ended December 31,
	2008	2007	2008	2007
Weighted average common shares	30,809,445	30,953,608	31,043,093	30,763,049
Dilutive common stock options	215,240	—	352,458	474,964

Weighted average common shares, assuming dilution	31,024,685	30,953,608	31,395,551	31,238,013

For the three-month period ended December 31, 2008, options to purchase 1,082,397 shares of our common stock were excluded from the calculation of diluted earnings per share because the exercise prices of the stock options were greater than or equal to the average price of the common shares.

Options to purchase 1,556,000 shares of common stock were excluded from the calculation of diluted earnings per share for the three-month period ended December 31, 2007, as the Company incurred a net loss during the period, and the effect of these options would be anti-dilutive.

For the nine-month periods ended December 31, 2008 and 2007, options to purchase 671,689 and 348,193 shares of our common stock were excluded from the calculation of diluted earnings per share because the exercise prices of the stock options were greater than or equal to the average price of the common shares.

At December 31, 2008, there were outstanding options to purchase 2,066,550 shares of our common stock at a weighted average exercise price of $4.33 per share.

4. Stock-Based Compensation

The Company follows the fair value recognition provisions of SFAS No. 123R, Share-Based Payment—An Amendment of FASB Statements No. 123 and 95,” or SFAS No. 123R, using the modified prospective transition method.

For the three and nine-month periods ended December 31, 2008, the Company recorded stock-based compensation expense of $225,793 and $584,629, respectively, for stock options granted under the Amended and Restated 2001 Repligen Corporation Stock Plan.

For the three and nine-month periods ended December 31, 2007, the Company recorded stock-based compensation expense of $131,944 and $390,100, respectively, for stock options granted under the Amended and Restated 2001 Repligen Corporation Stock Plan.

The Plans allow for the granting of incentive and nonqualified options and restricted stock and other equity awards to purchase shares of Common Stock. Incentive options granted to employees under the Plans generally vest over a four to five-year period, with 20%-25% vesting on the first anniversary of the date of grant and the remainder vesting in equal yearly installments thereafter. Nonqualified options issued to non-employee directors and consultants under the Plans generally vest over one year. Options granted

under the Plans have a maximum term of ten years from the date of grant and generally, the exercise price of the stock options equals the fair market value of the Company’s Common Stock on the date of grant. At the Company’s Annual Meeting on September 12, 2008, shareholders voted to approve the Second Amended and Restated 2001 Repligen Corporation Stock Plan, increasing the number of available options to purchase common stock by 1,000,000 shares. At December 31, 2008, options to purchase 1,759,050 shares were outstanding under the Second Amended and Restated 2001 Repligen Corporation Stock Plan and options to purchase 307,500 shares were outstanding under the 1992 Repligen Corporation Stock Option Plan. At December 31, 2008, 897,409 shares were available for future grant under the Second Amended and Restated 2001 Repligen Corporation Stock Plan.

The Company recognizes compensation expense on a straight-line basis over the requisite service period based upon options that are ultimately expected to vest, and accordingly, such compensation expense has been adjusted by an amount of estimated forfeitures. Forfeitures represent only the unvested portion of a surrendered option. SFAS No. 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. Based on an analysis of historical data, the Company has calculated an 8% annual forfeiture rate for non-director level employees, a 3% annual forfeiture rate for director level employees, and a 0% forfeiture rate for non-employee members of the Board of Directors, which it believes is a reasonable assumption to estimate forfeitures. However, the estimation of forfeitures requires significant judgment, and to the extent actual results or updated estimates differ from the Company’s current estimates, such amounts will be recorded as a cumulative adjustment in the period estimates are revised.

Information regarding option activity for the nine months ended December 31, 2008 under the Plans is summarized below:


	Options Outstanding		Weighted- Average Exercise Price Per Share		Weighted- Average Remaining Contractual Term (in years)	Aggregate Intrinsic Value
Options outstanding at April 1, 2008	1,622,750		$	3.78
Granted	581,000		$	5.54
Exercised	(111,600	)	$	2.31
Forfeited/Cancelled	(25,600	)	$	5.86

Options outstanding at December 31, 2008	2,066,550		$	4.33	6.49	$	1,019,568
Options exercisable at December 31, 2008	1,121,000		$	3.95	4.47	$	771,845
Vested and expected to vest at December 31, 2008 (1)	1,993,711		$	4.33	6.48	$	959,265

(1)

This represents the number of vested options as of December 31, 2008 plus the number of unvested options expected to vest as of December 31, 2008 based on the unvested outstanding options at December 31, 2008 adjusted for the estimated forfeiture rate of 8% for awards granted to non-director level employees and 3% for awards granted to director level employees as described above.

The aggregate intrinsic value in the table above represents the total pre-tax intrinsic value (the difference between the closing price of the Common Stock on December 31, 2008 of $4.78 and the exercise price of each in-the-money option) that would have been received by the option holders had all option holders exercised their options on December 31, 2008.

The weighted average grant date fair value of options granted during the nine months ended December 31, 2008 and 2007 was $3.46 and $2.98, respectively. The total fair value of stock options that vested during the nine months ended December 31, 2008 and 2007 was approximately $556,000 and $652,000, respectively.

As of December 31, 2008, there was approximately $2,151,900 of total unrecognized compensation cost related to unvested share-based awards. This cost is expected to be recognized over a weighted average remaining requisite service period of 2.98 years. The Company expects approximately 873,000 in unvested options to vest over the next five years.

5. Cash, Cash Equivalents and Marketable Securities

We follow the provisions of SFAS No. 115, “Accounting for Certain Investments in Debt and Equity Securities.” At December 31, 2008, our investments included money market funds as well as short-term and long-term marketable securities, which are classified as held-to-maturity investments as we have the positive intent and ability to hold to maturity. Accordingly, funds from investments designated as held to maturity are not available for immediate use. As a result, these investments are recorded at amortized cost. Marketable securities are investments with original maturities of greater than 90 days. Long-term marketable securities are investment grade securities with maturities of greater than one year.

At March 31, 2008, marketable securities also included investment grade auction rate securities. Auction rate securities have long-term underlying maturities, but have interest rates that are reset every 90 days or less, at which time the securities can typically be purchased or sold. Auction rate securities were classified as available-for-sale and reported at fair value. Due to the reset feature and their carrying value equaling their fair value, there were no gross unrealized gains or losses from these short-term investments. As of June 30, 2008, the Company had sold all remaining auction rate securities without incurring any losses. As of December 31, 2008, the Company holds no auction rate securities.

Cash, cash equivalents and marketable securities consist of the following:


	December 31, 2008		March 31, 2008
Cash and cash equivalents	$	14,987,843	$	32,562,138

Marketable securities:
Auction rate securities	$	—	$	900,000
U.S. Government and agency securities		9,626,138		—
Corporate and other debt securities		21,731,516		16,321,653

	$	31,357,654	$	17,221,653

Long-term marketable securities:
U.S. Government and agency securities	$	10,360,617	$	—
Corporate and other debt securities		7,803,356		10,805,263

	$	18,163,973	$	10,805,263

The average remaining maturity of marketable securities at December 31, 2008 is approximately 8.86 months.

Restricted cash of $200,000 is related to our facility lease obligation.

6. Fair Value Measurement

In February 2007, the FASB issued SFAS No. 159, “The Fair Value Option for Financial Assets and Financial Liabilities — including an Amendment of FASB Statement No. 115” (“SFAS 159”), which allows an entity to choose to measure certain financial instruments and liabilities at fair value. Subsequent measurements for the financial instruments and liabilities an entity elects to fair value will be recognized in earnings. SFAS 159 also establishes additional disclosure requirements. SFAS 159 was effective for the Company beginning April 1, 2008. The adoption of SFAS 159 did not have a material impact on our condensed consolidated statement of financial position, results of operations or cash flows. We did not elect to remeasure any existing financial assets or liabilities under the provisions of SFAS 159.

In September 2006, the Financial Accounting Standards Board (FASB) issued Statement of Financial Accounting Standards (SFAS) No. 157, “Fair Value Measurements,” effective for financial statements issued for fiscal years beginning after November 15, 2007. SFAS No. 157 replaces multiple existing definitions of fair value with a single definition, establishes a consistent framework for measuring fair value and expands financial statement disclosures regarding fair value measurements. This Statement applies only to fair value measurements that already are required or permitted by other accounting standards and does not require any new fair value measurements. In February 2008, the FASB issued FASB Staff Position (FSP) No. 157-2, which delayed until January 1, 2009 the effective date of SFAS No. 157 for nonfinancial assets and liabilities that are not recognized or disclosed at fair value in the financial statements on a recurring basis.

The adoption of SFAS No. 157 for our financial assets and liabilities in the first quarter of fiscal 2009 did not have a material impact on our financial position or results of operations. Our nonfinancial assets and liabilities that meet the deferral criteria set forth in FSP No. 157-2 include property, plant and equipment. We do not expect that the adoption of SFAS No. 157 for these nonfinancial assets and liabilities will have a material impact on our financial position or results of operations.

In determining the fair value of its financial assets and liabilities, the Company uses various valuation approaches. SFAS 157 establishes a hierarchy for inputs used in measuring fair value that maximizes the use of observable inputs and minimizes the use of unobservable inputs by requiring that observable inputs be used when available. Observable inputs are inputs that market participants would use in pricing the asset or liability based on market data obtained from sources independent of the Company. Unobservable inputs are inputs that reflect the Company’s assumptions about the inputs that market participants would use in pricing the asset or liability and are developed based on the best information available in the circumstances. The fair value hierarchy is broken down into three levels based on the source of inputs as follows:


Level 1	–	Valuations based on unadjusted quoted prices in active markets for identical assets or liabilities that the Company has the ability to access

Level 2	–	Valuations based on quoted prices for similar assets or liabilities in active markets, quoted prices for identical or similar assets or liabilities in markets that are not active and models for which all significant inputs are observable, either directly or indirectly

Level 3	–	Valuations based on inputs that are unobservable and significant to the overall fair value measurement

The availability of observable inputs can vary among the various types of financial assets and liabilities. To the extent that the valuation is based on models or inputs that are less observable or unobservable in the market, the determination of fair value requires more judgment. In certain cases, the inputs used to measure fair value may fall into different levels of the fair value hierarchy. In such cases, for financial statement disclosure purposes, the level in the fair value hierarchy within which the fair value measurement is categorized is based on the lowest level input that is significant to the overall fair value measurement.

The Company’s held-to-maturity securities, which are fixed income investments, are comprised of obligations of U.S. government agencies, corporate debt securities and other interest bearing securities. These held-to-maturity securities are recorded at amortized cost and are therefore not included in our market value measurement disclosure. Money market funds are valued using quoted market prices with no valuation adjustments applied. Accordingly, these securities are categorized in Level 1.

The following fair value hierarchy table presents information about each major category of the Company’s financial assets and liabilities measured at fair value on a recurring basis as of December 31, 2008:


	Fair value measurement at reporting date using:
	Quoted prices in active markets for identical assets (Level 1)		Significant other observable inputs (Level 2)	Significant unobservable inputs (Level 3)	Balance as of December 31, 2008
Assets:
Money market funds	$	104,830			$	104,830

There were no remeasurements to fair value during the nine months ended December 31, 2008 of financial assets and liabilities that are not measured at fair value on a recurring basis.

7. Inventories

Inventories relate to the Company’s Protein A business. The Company values inventory at the lower of cost or market on a first-in, first-out basis. Cost includes material, labor and applicable manufacturing overhead costs. The Company reviews its inventories at least quarterly and records a provision for excess and obsolete inventory based on its estimates of expected sales volume, production capacity and expiration dates of raw materials, work in process and finished goods. Expected sales volumes are determined based on supply forecasts provided by key customers for the next three to twelve months. The Company writes down inventory that has become obsolete, has a cost basis in excess of its expected net realizable value, or is in excess of expected requirements to cost of goods sold. Protein A finished goods are manufactured to order and tested for quality specifications prior to shipment.

A change in the estimated timing or amount of demand for our products could result in additional provisions for excess inventory quantities on hand. Any significant unanticipated changes in demand or unexpected quality failures could have a significant impact on the value of inventory and reported operating results. During all periods presented in the accompanying financial statements, there have been no material adjustments related to a revised estimate of inventory valuations.

Inventories consist of the following:


	December 31, 2008		March 31, 2008
Raw materials	$	1,535,051	$	1,676,402
Work in process		897,351		676,769
Finished goods		89,510		451,076

	$	2,521,912	$	2,804,247

8. Accrued Expenses and Other Current Liabilities

The Company prepares its financial statements in accordance with accounting principles generally accepted in the United States. These principles require that the Company estimate accrued liabilities. This process involves identifying services performed on the

Company’s behalf and estimating the level of service performed and the associated cost incurred for such service as of each balance sheet date. Examples of estimated accrued expenses include: 1) Fees paid to contract manufacturers in conjunction with the production of clinical materials. These expenses are normally determined through a contract or purchase order issued by the Company; 2) Service fees paid to organizations for their performance in conducting clinical trials. These expenses are determined by contracts in place for those services and communications with project managers on costs which have been incurred as of each reporting date; 3) Professional and consulting fees incurred with law firms, audit and accounting service providers and other third party consultants. These expenses are determined by either requesting those service providers to estimate unbilled services at each reporting date for services incurred, or tracking costs incurred by service providers under fixed fee arrangements. The Company has processes in place to estimate the appropriate amounts to record for accrued liabilities, which principally involve the applicable personnel reviewing the services provided. In the event that the Company does not identify certain costs which have begun to be incurred or the Company under or over-estimates the level of services performed or the costs of such services, the reported expenses for that period may be too low or too high. The date on which certain services commence, the level of services performed on or before a given date, and the cost of such services are often judgmental. The Company makes these judgments based upon the facts and circumstances known at the date of the financial statements.

A change in the estimated cost or volume of services provided could result in additional accrued liabilities. Any significant unanticipated changes in such estimates could have a significant impact on our accrued liabilities and reported operating results. There has been no material adjustments to our accrued liabilities in any of the periods presented in the accompanying financial statements.

Accrued expenses and other current liabilities consist of the following:


	December 31, 2008		March 31, 2008
Employee compensation	$	590,538	$	621,982
Royalty and license fees		288,600		97,804
Research & development		629,625		201,825
Professional fees		143,600		451,287
Other accrued expenses		111,420		217,874
Other current liabilities		212,741		217,162
Unearned revenue		125,000		59,965

	$	2,101,524	$	1,867,899

9. Income Taxes

The Company had income before taxes of approximately $8,614,000 and $41,132,000 for the nine month periods ended December 31, 2008 and 2007, respectively. The Company had income tax provisions of approximately $175,000 and $827,000 for the nine month periods ended December 31, 2008 and 2007, respectively. In the current period, our effective tax rate benefited from the recognition of approximately $40,000 in research and development tax credits. For the nine months ended December 31, 2008, the effective income tax rate was approximately 2.49%. The effective income tax rate is based upon the estimated income for the year and the composition of the income in different jurisdictions. The effective tax rate differs from the statutory tax rate due to the utilization of prior year net operating losses and credits, offset by the effects of the alternative minimum tax on income derived during the fiscal year.

The Company has net operating loss carryforwards of approximately $63,050,000, business tax credits carryforwards of approximately $2,205,000, and other tax credits of approximately $733,000 available to reduce future federal income taxes, if any. Additionally, the Company also has business tax credit carryforwards of approximately $2,665,000 available to reduce future state income taxes, if any. The Company has utilized all available state net operating loss carryforwards. The net operating loss and business tax credits carryforwards will continue to expire at various dates through March 2026. The net operating loss and business tax credit carryforwards are subject to review and possible adjustment by the Internal Revenue Service and may be limited in the event of certain changes in the ownership interest of significant stockholders.

As of December 31, 2008, a full valuation allowance has been provided against the net operating losses, business tax credits and other deferred tax assets, as it is uncertain if the Company will realize the benefits of such deferred tax assets.

10. Comprehensive Income/Loss

We follow the provisions of SFAS No. 130, “Reporting Comprehensive Income” (“SFAS 130”). SFAS 130 requires disclosure of all components of comprehensive income on an annual and interim basis. Comprehensive income is defined as the change in equity of a business enterprise during a period resulting from transactions and other events and circumstances from non-owner sources. Our comprehensive income is equal to our reported net income for all periods presented.

11. Segment Reporting

We follow the provisions of SFAS No. 131, “Disclosures about Segments of an Enterprise and Related Information” (“SFAS 131”). SFAS 131 establishes standards for reporting information regarding operating segments in annual financial statements and requires selected information for those segments to be presented in interim financial reports issued to stockholders. SFAS 131 also establishes standards for related disclosures about products and services and geographic areas. The chief operating decision maker, or decision-making group, in making decisions regarding how to allocate resources and assess performance, identifies operating segments as components of an enterprise about which separate discrete financial information is available for evaluation. To date, we view our operations and manage our business as one operating segment. As a result, the financial information disclosed herein represents all of the material financial information related to our principal operating segment.

The following table represents the Company’s revenue by geographic area (based on the location of the customer):


	Three months ended December 31,				Nine months ended December 31,
	2008		2007		2008		2007
Sweden	47	%	75	%	38	%	63	%
US	48	%	20	%	57	%	30	%
Other	5	%	5	%	5	%	7	%

	100	%	100	%	100	%	100	%

Royalty revenue from Bristol represented 36% of the Company’s total revenue for the three months ended December 31, 2008 and 48% for the nine months ended December 31, 2008. The Company’s largest Protein A customer accounted for 47% of total revenues for the three months ended December 31, 2008 and 39% of revenues for the nine months ended December 31, 2008. The Company’s largest Protein A customer accounted for 76% of total revenues for the three months ended December 31, 2007. The Company’s two largest Protein A customers accounted for 65% and 14% of revenues for the nine months ended December 31, 2007.

At December 31, 2008, Bristol’s royalty payment comprised 53% of our accounts receivable. One of the Company’s largest Protein A customers accounted for 25% of our accounts receivable as of December 31, 2008. Two of the Company’s largest Protein A customers accounted for 20% and 24% of accounts receivable as of March 31, 2008, respectively.

12. New Accounting Pronouncements

In December 2007, the Financial Accounting Standards Board (“FASB”) issued SFAS No. 141(R), “Business Combinations” (“SFAS 141(R)”) and SFAS No. 160, “Accounting and Reporting of Noncontrolling Interests in Consolidated Financial Statements — an amendment of ARB No. 51” (“SFAS 160”). These standards will significantly change the accounting and reporting for business combination transactions and noncontrolling (minority) interests in financial statements, including capitalizing at the acquisition date the fair value of acquired in process research and development projects, and remeasuring and writing down these assets, if necessary, in subsequent periods during their development. The new standards will be applied prospectively for business combinations that occur for the Company on or after April 1, 2009, except that presentation and disclosure requirements of SFAS 160 regarding minority interests shall be applied retrospectively. The Company does not currently believe that adoption will have a material impact on its results of operations, financial position or cash flows.

In December 2007, the FASB ratified EITF No. 07-1, “Accounting for Collaborative Agreements” (“EITF 07-1”). EITF 07-1 provides guidance regarding financial statement presentation and disclosure of collaborative arrangements, as defined, which includes arrangements the Company has entered into regarding development and commercialization of products. EITF 07-1 is effective for the Company as of April 1, 2009. The Company has not yet completed its evaluation of EITF 07-1, but does not currently believe that adoption will have a material impact on its results of operations, financial position or cash flows.

On April 1, 2008, the Company adopted EITF Issue No. 07-03, “Accounting for Nonrefundable Advance Payments for Goods or Services to Be Used in Future Research and Development Activities” (“EITF 07-03”). EITF 07-03 requires companies to defer and capitalize, until the goods have been delivered or the related services have been rendered, non-refundable advance payments for goods that will be used or services that will be performed in future research and development activities. The adoption of EITF 07-03 on April 1, 2008 did not have a material impact on the Company’s financial condition or results of operations.

13. Scripps Agreements

License Agreement

On April 6, 2007 (the “Effective Date”), the Company entered into an exclusive worldwide commercial license agreement (“License Agreement”) with The Scripps Research Institute (“Scripps”). Pursuant to the License Agreement, the Company obtained a license to use, commercialize and sublicense certain patented technology and improvements thereon, owned or licensed by Scripps, relating to compounds which may have utility in treating Friedreich’s Ataxia, an inherited neurodegenerative disease. Research in tissues derived from patients, as well as, in mice, indicates that the licensed compounds increase production of the protein frataxin, which suggests potential utility of these compounds in slowing or stopping progression of the disease. There are currently no approved treatments for Friedreich’s Ataxia.

Pursuant to the License Agreement, the Company agreed to pay Scripps an initial license fee of $300,000, certain royalty and sublicense fees and, in the event the Company achieves specified developmental and commercial milestones, certain additional milestone payments. In addition, the Company issued Scripps 87,464 shares of the Company’s common stock (the “Shares”) representing $300,000 as of the Effective Date. The Company recorded the initial license payment and the value of the shares issued as research and development costs in the Company’s statement of operations in the first quarter of fiscal 2008.

If the value of the Shares did not equal at least $300,000 on the one-year anniversary of the Effective Date, the Company would have had to make a cash payment to Scripps equal to the difference. At April 6, 2008, the one-year anniversary of the Effective Date, the fair value of the shares exceeded $300,000; therefore, no liability was recorded. Furthermore, the Company issued warrants to an individual at Scripps to purchase up to 150,000 shares of common stock. The warrants have a 7-year term and are exercisable based on performance criteria as detailed in the warrant agreement. No expense has been recorded related to these warrants in fiscal 2008 or for the nine-month period ended December 31, 2008, as none of the performance criteria have been achieved. At this time, the Company does not believe that the performance criteria are probable of being achieved in the near future.

The License Agreement with Scripps expires or may be terminated (i) when all of the royalty obligations under the License Agreement expire; (ii) at any time by mutual written consent; (iii) by Scripps if the Company (a) fails to make payments under the License Agreement, (b) fails to achieve certain developmental and commercial objectives, (c) becomes insolvent, (d) is convicted of a felony relating to the manufacture, use or sale of the licensed technology, or (e) defaults in its performance under the License Agreement; or (iv) by the Company upon 90 days written notice.

Research Funding and Option Agreement

On October 26, 2007, the Company entered into a research funding and option agreement (“Funding Agreement”) with Scripps to fund a research program for the research and development of compounds that may have utility in the treatment of Friedreich’s Ataxia. Pursuant to the Funding Agreement, the Company is required to fund approximately $140,000 annually, payable quarterly, which are recorded as research and development expenses. In exchange for funding the research, Scripps will grant an exclusive option to the Company to acquire a sole, worldwide license, including the right to sublicense, manufacture and sell products, and services that result from the research program. There are no guaranties or warranties that products or services may result from the research program, and the Company has ascribed no value to the license.

The Funding Agreement expires or may be terminated (i) when all of the royalty obligations under the Funding Agreement expire; (ii) at any time by mutual written consent; (iii) by Scripps if the Company (a) fails to make payments under the Funding Agreement, (b) fails to achieve certain developmental and commercial objectives, (c) becomes insolvent, (d) is convicted of a felony relating to the manufacture, use or sale of the licensed technology, or (e) defaults in its performance under the Funding Agreement; or (iv) by the Company upon 90 days written notice.

14. Legal Proceedings

ImClone Systems

In May 2004, the Company and the Massachusetts Institute of Technology (“MIT”) filed an action in the United States District Court for the District of Massachusetts against ImClone Systems, Incorporated (“ImClone”) for infringement of U.S. Patent No. 4,663,281 (“the ‘281 patent”) based on ImClone’s manufacture and sale of Erbitux^®. The ‘281 patent, which covers the use of certain genetic elements that increase protein production in a mammalian cell, is assigned to MIT and exclusively licensed to Repligen.

On September 10, 2007, the Company and MIT entered into a settlement agreement (the “ImClone Settlement”) with ImClone relating to the lawsuit against ImClone for infringement of the ‘281 patent. Pursuant to the ImClone Settlement, ImClone made a payment of $65 million to Repligen and MIT that resulted in net proceeds to Repligen of $40.17 million, as follows:


Gross proceeds from ImClone Settlement agreement	$	65,000,000
Less: Amounts paid to MIT		(11,000,000	)
Less: Legal fees and other costs		(13,830,000	)

Net gain on litigation settlement	$	40,170,000

The ImClone Settlement served as the basis for the Company and MIT to dismiss the lawsuit against ImClone and for the Company to grant ImClone a non-exclusive sublicense to the ‘281 patent and certain other intellectual property. There are no further obligations to the Company with respect to the sublicenses. The net gain on litigation settlement was recorded as a separate component of operating expenses in the Company’s statement of operations in fiscal 2008.

Bristol-Myers Squibb Company

In January 2006, Repligen and the University of Michigan jointly filed a complaint against Bristol in the United States District Court for the Eastern District of Texas for infringement of U.S. Patent No. 6,685,941 (“the ‘941 patent”) for the commercial sale of Orencia^®. The ‘941 patent, entitled “Methods of Treating Autoimmune Disease via CTLA4-Ig,” covers methods of using CTLA4-Ig to treat rheumatoid arthritis, as well as other therapeutic methods. Repligen has exclusive rights to this patent from its owners, the University of Michigan and the U.S. Navy. In February 2006, Bristol answered the complaint and counterclaimed seeking a declaratory judgment that the ‘941 patent is invalid and unenforceable and that Bristol does not infringe the patent.

On April 7, 2008, Repligen and the University of Michigan entered into a settlement agreement (the “Bristol Settlement”) with Bristol relating to the lawsuit against Bristol for infringement of the ‘941 patent. Pursuant to the Bristol Settlement, Bristol made an initial payment of $5 million to Repligen. The settlement further provides for Bristol to pay royalties on the United States net sales of Orencia^® for any clinical indication at a rate of 1.8% for the first $500 million of annual net sales, 2.0% for the next $500 million of annual net sales and 4% of annual net sales in excess of $1 billion for each year from January 1, 2008 until December 31, 2013. Pursuant to the Bristol Settlement agreement, the Company has recognized $11.6 million in royalty revenue in the nine month period ended December 31, 2008, including a $5 million initial payment, $1.3 million for sales of Orencia^® from January 1, 2008 through December 31, 2008, as well as $5.3 million for sales in the first three quarters of fiscal year 2009 (see Note 2). The Bristol Settlement served as the basis for Repligen and the University of Michigan to dismiss the lawsuit against Bristol and for Repligen and the University of Michigan to grant to Bristol an exclusive worldwide license to the ‘941 patent and certain other intellectual property.

Repligen must also remit to the University of Michigan 15% of all royalty revenue received from Bristol, after first deducting certain legal and other costs incurred related to the settlement. The Company has incurred approximately $6.1 million in such legal costs, which when deducted from the $11.6 million in royalty revenue earned to date, results in a net amount due to the University of Michigan of $828,000. This operating expense has been included on our Statements of Operations under the line item “Cost of royalty and other revenue”.

15. Share Repurchase

In June 2008, the Board of Directors authorized a program to repurchase up to 1.25 million of our common stock to be repurchased at the discretion of management from time to time in the open market or through privately negotiated transactions. The repurchase program has no set expiration date and may be suspended or discontinued at any time. We publicly announced the stock repurchase program on June 18, 2008. For the nine-month periods ended December 31, 2008, the Company repurchased 492,827 shares of common stock, for an aggregate purchase price of $1,954,455, leaving 757,173 shares remaining under this authorization.

ITEM 2.

MANAGEMENT’S DISCUSSION AND ANALYSIS OF FINANCIAL CONDITION AND RESULTS OF OPERATIONS

Overview

We are a biopharmaceutical company focused primarily on the development of novel therapeutics for diseases that affect the central nervous system. A number of drug development programs are currently being conducted to evaluate our drug candidates in diseases such as bipolar disorder and neurodegeneration. In addition, we sell Protein A for monoclonal antibody purification and receive royalties on intellectual property that we license to third parties. Our business strategy is to deploy the profits from our current commercial products and patents licensing revenues to enable us to invest in the development of our therapeutic product candidates while reducing our financial risk.

Critical Accounting Policies and Estimates

A “critical accounting policy” is one which is both important to the portrayal of the Company’s financial condition and results and requires management’s most difficult, subjective or complex judgments, often as a result of the need to make estimates about the effect of matters that are inherently uncertain. For additional information, please see the discussion of our significant accounting policies in Note 2 to the Financial Statements included in our Annual Report on Form 10-K dated March 31, 2008.

Results of Operations

Three month period ended December 31, 2008 vs. December 31, 2007

Total revenue

Total revenues for the three-month periods ended December 31, 2008 and December 31, 2007 were approximately $6,018,000 and $4,664,000 respectively, an increase of $1,354,000 or 29%.

Sales of Protein A for the three-month periods ended December 31, 2008 and December 31, 2007 were $3,294,000 and $3,921,000, respectively. The decrease of $627,000, or 16%, was largely the result of lower overall sales volume as the prior year period was unusually high as a result of the timing of customer orders.

Substantially all of our products based on recombinant Protein A are sold to customers who incorporate our manufactured products into their proprietary antibody purification systems to be sold directly to the pharmaceutical industry. Monoclonal antibodies are a well-established class of drug with applications in rheumatoid arthritis, asthma, Crohn’s disease and a variety of cancers. Sales of Protein A are therefore impacted by the timing of large-scale production orders and on the regulatory approvals for such antibodies, which may result in significant quarterly fluctuations.

In April 2008, we settled our outstanding litigation with Bristol. We have therefore begun recognizing royalty revenue in fiscal year 2009 for Bristol’s net sales in the United States of Orencia^® which is used in the treatment of rheumatoid arthritis. Pursuant to the Bristol Settlement, we have recognized $1,924,000 in royalty revenue in the three months ended December 31, 2008. Additionally, during the three-month periods ended December 31, 2008 and December 31, 2007, we earned and recognized approximately $254,000 and $76,000, respectively, in royalty revenue from ChiRhoClin.

During the three-month periods ended December 31, 2008, and December 31, 2007, we recognized approximately $564,000 and $25,000, respectively, of revenue from various sponsored research and development projects. Research revenue is recognized for costs plus fixed-fee contracts as costs are incurred or for certain contracts, based upon the delivery of agreed upon milestones.

As previously disclosed, we have ceased sales of SecreFlo^® in the current year due to the expiration of our agreement with our sole supplier, ChiRhoClin. There were no sales of SecreFlo^® in the current quarter and we will no longer sell the product going forward. Sales of SecreFlo^® for the quarter ended December 31, 2007 were $642,000.

Operating expenses

Total operating expenses were approximately $6,556,000 and $5,663,000 for the three-month periods ended December 31, 2008 and December 31, 2007, respectively, an increase of $893,000 or 16%.

Cost of product revenue was approximately $1,287,000 and $1,730,000 for the three-month periods ended December 31, 2008 and December 31, 2007, respectively, a decrease of $443,000 or 26%. This decrease is primarily due to the decrease in Protein A sales noted above, offset by incremental spending to enhance product quality and expand our manufacturing capacity.

In connection with the Bristol Settlement, we must remit 15% of royalty revenue received through the expiration of the settlement agreement in December 2013, after deducting certain allowable legal and other costs, to the University of Michigan. For the three-month period ended December 31, 2008, this cost of royalty revenue was $286,000.

Research and development expenses were approximately $3,579,000 and $1,592,000 for the three-month periods ended December 31, 2008 and December 31, 2007, respectively, an increase of $1,987,000 or 125%. Patient enrollment continues to progress in our phase 3 clinical trial for RG1068, evaluating the use of human secretin in aiding pancreatic imaging, and as a result spending on this program has increased approximately $493,000 compared to the prior period. We have begun patient enrollment and engaged a clinical research organization to help lead our phase 2b clinical trial for RG2417, evaluating the use of uridine to treat bi-polar depression. As a result, we have increased spending by $836,000 compared to the prior period. Finally, our Friedreich’s ataxia spending has also increased by $270,000 as we continue our research efforts to identify a clinical candidate. Significant fluctuations in research and development expenses may occur from period to period depending on the nature, timing, and extent of development activities over any given period of time.

Selling, general and administrative expenses were approximately $1,404,000 and $2,341,000 for the three-month periods ended December 31, 2008 and December 31, 2007, respectively, a decrease of $937,000 or 40%. This decrease is largely attributable to a $1,157,000 decrease in litigation expenses related to our patent infringement settlements with both ImClone and Bristol, offset by increased headcount and recruiting costs as we expand our business development and other functions to support the business.

Interest income

Interest income was approximately $473,000 and $760,000 for the three-month periods ended December 31, 2008 and December 31, 2007, respectively. The decrease is primarily due to lower overall investment yields during the three month period ended December 31, 2008 as the credit crisis impacted global financial markets.

Income Tax Provision

The Company had losses before taxes of approximately $66,000 and $242,000 for the three month periods ended December 31, 2008 and 2007, respectively. The Company had an income tax benefit of $85,000 for the three month periods ended December 31, 2008, due largely to the recognition of approximately $40,000 in research and development tax credits. Prior to the $40.2 million litigation gain in the second quarter of fiscal 2008, the Company had net operating losses and other research credits that reduced our effective tax rate to zero. For fiscal year 2009, we anticipate an effective tax rate of approximately 2.49%. The effective tax rate differs from the statutory tax rate due to the continued utilization of prior year net operating losses and credits, offset by the effects of the alternative minimum tax (“AMT”) on income derived during the fiscal year.

Nine month period ended December 31, 2008 vs. December 31, 2007

Total revenue

Total revenues for the nine-month periods ended December 31, 2008 and December 31, 2007 were approximately $24,768,000 and $15,996,000 respectively, an increase of $8,772,000 or 55%.

Sales of Protein A for the nine-month periods ended December 31, 2008 and December 31, 2007 were $11,803,000 and $13,667,000 respectively. The decrease of $1,864,000, or 14%, was largely the result of lower overall sales volume as the prior period was unusually high as a result of the timing of customer orders.

In April 2008, we settled our outstanding litigation with Bristol. We have therefore begun recognizing royalty revenue in fiscal year 2009 for Bristol’s net sales in the United States of Orencia^® which is used in the treatment of rheumatoid arthritis. Pursuant to the Bristol Settlement, we have recognized $11,584,000 in royalty revenue in the nine-month period ended December 31, 2008. Additionally, during the nine-month periods ended December 31, 2008 and December 31, 2007, we earned and recognized approximately $539,000 and $179,000, respectively, in royalty revenue from ChiRhoClin.

During the nine-month periods ended December 31, 2008, and December 31, 2007, we recognized approximately $674,000 and $365,000, respectively, of revenue from various sponsored research and development projects. Research revenue is recognized for costs plus fixed-fee contracts as costs are incurred or for certain contracts, based upon the delivery of agreed upon milestones.

As previously disclosed, we have ceased sales of SecreFlo^® in the current year due to the expiration of our agreement with our sole supplier, ChiRhoClin. Sales of SecreFlo^® for the nine-month periods ended December 31, 2008 and December 31, 2007 were $168,000 and $1,784,000, respectively.

Operating expenses

Total operating expenses, exclusive of the net gain from litigation settlement, were approximately $17,672,000 and $16,409,000 for the nine-month periods ended December 31, 2008 and December 31, 2007, respectively, an increase of $1,263,000 or 8%.

Cost of product revenue was approximately $4,344,000 and $4,857,000 for the nine-month periods ended December 31, 2008 and December 31, 2007, respectively, a decrease of $513,000 or 11%. This decrease is primarily due to the decrease in Protein A sales noted above, offset by increased spending to enhance product quality and increased occupancy expenses related to expansion of our manufacturing capacity.

In connection with the Bristol Settlement, we must remit 15% of royalty revenue received through the expiration of the settlement agreement in December 2013, after deducting certain allowable legal and other costs, to the University of Michigan. For the nine-month period ended December 31, 2008, this cost of royalty revenue was $822,000.

Research and development expenses were approximately $8,127,000 and $4,883,000 for the nine-month periods ended December 31, 2008 and December 31, 2007, respectively, an increase of $3,244,000 or 66%. The increase is due primarily to increased overall activity, in comparison to the prior period, in our two clinical trials as well as ongoing research and development costs incurred investigating potential clinical candidates to be used in the treatment of Friedreich’s ataxia. Specifically, as patient enrollment continues to progress in our phase 3 clinical trial for RG1068, evaluating the use of human secretin in aiding pancreatic imaging, we have increased spending versus the prior period by $1,140,000. In addition, we have engaged a clinical research organization to assist in the deployment of our phase 2b clinical trial for RG2417, evaluating the use of uridine to treat bi-polar depression, and otherwise increased overall clinical trial efforts, adding an incremental $1,120,000 of spending compared to the prior period. Finally, our Friedreich’s ataxia spending has also increased by $934,000 as we continue our research efforts. Significant fluctuations in research and development expenses may occur from period to period depending on the nature, timing, and extent of development activities over any given period of time.

Selling, general and administrative expenses were approximately $4,380,000 and $6,669,000 for the nine-month periods ended December 31, 2008 and December 31, 2007, respectively, a decrease of $2,289,000 or 34%. This decrease is largely attributable to a $2,997,000 decrease in litigation expenses related to our patent infringement settlements with both ImClone and Bristol, partially offset by increased headcount, recruiting and consulting costs as we expand our business development efforts and other functions to support the business.

Interest income

Interest income was approximately $1,521,000 and $1,383,000 for the nine-month periods ended December 31, 2008 and December 31, 2007, respectively. The increase is primarily due to a significantly higher average investment balance during the entire nine-month period ended December 31, 2008, offset by lower overall returns experienced during the recent credit crisis.

Income Tax Provision

The Company had income before taxes of approximately $8,614,000 and $41,132,000 for the nine-month periods ended December 31, 2008 and 2007, respectively. The Company had an income tax provision of $175,000 and $827,000 for the nine-month periods ended December 31, 2008 and 2007, respectively. In the current year, the tax provision was benefited by the recognition of approximately $40,000 in research and development tax credits. Prior to the $40.2 million litigation gain in the second quarter of fiscal 2008, the company had net operating losses and other research credits that reduced our effective tax rate to zero. For fiscal year 2009, we anticipate an effective tax rate of approximately 2.49%. The effective tax rate differs from the statutory tax rate due to the continued utilization of prior year net operating losses and credits, offset by the effects of the alternative minimum tax (“AMT”) on income derived during the fiscal year.

The Company has net operating loss carryforwards of approximately $63,050,000, business tax credits carryforwards of approximately $2,205,000, and other tax credits of approximately $733,000 available to reduce future federal income taxes, if any. Additionally, the Company also has business tax credits carryforwards of approximately $2,665,000 available to reduce future state income taxes, if any. The Company has utilized all available state net operating loss carryforwards. The net operating loss and business tax credits carryforwards will continue to expire at various dates through March 2026. The net operating loss and business tax credit carryforwards are subject to review and possible adjustment by the Internal Revenue Service and may be limited in the event of certain changes in the ownership interest of significant stockholders.

Liquidity and capital resources

We have financed our operations primarily through sales of equity securities, revenues derived from product sales and grant and research agreements and more recently from consideration received as a result of the successful settlement of litigation. Our revenue for the foreseeable future will be primarily limited to our product revenue related to Protein A, royalties from Bristol for their United States net sales of Orencia^®, research grants, interest income and other revenue. Revenues derived from the sales of SecreFlo^® vials, as anticipated and previously disclosed, have ceased during the year. Given the uncertainties related to pharmaceutical product development, we are currently unable to reliably estimate when, if ever, our therapeutic product candidates will generate revenue and cash flows. Total cash, cash equivalents and marketable securities at December 31, 2008 totaled approximately $64,509,000, an increase of $3,920,000 from $60,589,000 at March 31, 2008.

Operating activities

Our operating activities provided cash of approximately $6,402,000 for the nine-month period ended December 31, 2008. Cash provided by operations is primarily due to net income of $8,439,000, plus certain non-cash expenses such as $783,000 for depreciation and $579,000 in stock-based compensation expense, and a $282,000 increase in inventory, offset by a $2,114,000 increase in royalties receivable, a $641,000 increase in accounts receivable, and a $796,000 decrease in accounts payable and accrued liabilities. Royalties receivable increased primarily as a result of the $1,924,000 royalty revenue from Bristol for Orencia^® sales for the three-months ended December 31, 2008 which were recognized when earned but is not due until after quarter end. Accounts receivable increased as a result of the timing of customer payments, most of which were received just subsequent to our period end. The decrease in accounts payable and accrued expenses from year end was largely the result of the payment of outstanding legal invoices associated with the Bristol litigation that was completed in April 2008 offset by the timing of payments related to increased research, development and clinical activities.

Investing activities

Our investing activities consumed approximately $22,248,000 for the nine-month period ended December 31, 2008 as we made $21,495,000 net purchases of marketable securities, investing the funds provided by our operating activities above. In addition, the Company invested approximately $754,000 in equipment purchases and improvements to the Company’s facility.

Financing activities

Stock option exercises provided cash proceeds of approximately $264,000 for the nine-month period ended December 31, 2008. Share repurchases for the period consumed $1,954,000.

We do not currently use derivative financial instruments. We generally place our marketable security investments in high quality credit instruments as specified in our investment policy guidelines.

Working capital decreased slightly to approximately $49,774,000 at December 31, 2008 from $49,831,000 at March 31, 2008 as the company invested a portion of the cash flows from operations into long term investments and also expended $1,954,000 on share repurchase during the nine-month period ended December 31, 2008.

Our future capital requirements will depend on many factors, including the following:

•

the success of our clinical studies;

•

the scope of and progress made in our research and development activities;

•

our ability to acquire additional product candidates;

•

the success of any proposed financing efforts; and

•

the ability to sustain sales and profits of our commercial products.

Absent acquisitions of additional products, product candidates or intellectual property, we believe our current cash and investment balances are adequate to meet our needs for at least the next twenty four months. Our future capital requirements include, but are not limited to, continued investment in our research and development programs, capital expenditures primarily associated with purchases of equipment and facilities and continued investment in our intellectual property portfolio.

We plan to continue to invest in key research and development activities. We actively evaluate various strategic transactions on an ongoing basis, including licensing or acquiring complementary products, technologies or businesses that would complement our existing portfolio of development programs. We continue to seek to acquire such potential assets that may offer us the best opportunity to create value for our shareholders. In order to acquire such assets, we may need to seek additional financing to fund these investments. This may require the issuance or sale of additional equity or debt securities. The sale of additional equity may result in dilution to our stockholders. Should we need to secure additional financing to acquire a product, fund future investment in research and development, or meet our future liquidity requirements, we may not be able to secure such financing, or obtain such financing on favorable terms because of the volatile nature of the biotechnology marketplace.

The forward-looking statements in this Quarterly Report on Form 10-Q do not constitute guarantees of future performance. Investors are cautioned that statements in this Quarterly Report on Form 10-Q which are not strictly historical statements, including, without limitation, statements regarding current or future financial performance, management’s strategy, litigation strategy, costs of legal proceedings, disputes with suppliers, plans and objectives for future operations, clinical trials and results, marketing plans, revenue potential of therapeutic product candidates, product research, intellectual property and development, manufacturing plans and performance, delays in manufacturing by us or our partners, timing of customer orders, the anticipated growth in our target markets, including, without limitation, the market for neuropsychiatric disorders treatment, the market for pancreatic disease treatment, the monoclonal antibody market and the process chromatography industry and projected growth in product sales, costs of operations, sufficiency of funds to meet management objectives and availability of financing and effects of accounting pronouncements constitute forward-looking statements. Such forward-looking statements involve known and unknown risks, uncertainties and other factors that could cause our actual results to be materially different from the historical results or from any results expressed or implied by such forward-looking statements, including, without limitation, risks associated with: the success of current and future collaborative relationships, the success of our clinical trials and our ability to develop and commercialize products, our ability to obtain required regulatory approvals, our compliance with all Food and Drug Administration regulations, our ability to obtain, maintain and protect intellectual property rights for our products, the risk of litigation regarding our patent and other intellectual property rights, the risk of litigation with collaborative partners, our limited sales and marketing experience and capabilities, our limited manufacturing capabilities and our dependence on third-party manufacturers and value-added resellers, our ability to hire and retain skilled personnel, the market acceptance of our products, our ability to compete with larger, better financed pharmaceutical and biotechnology companies that may develop new approaches to the treatment of our targeted diseases, our history of losses and expectation of incurring continued losses, our ability to generate future revenues, our ability to raise additional capital to continue our drug development programs, our volatile stock price, and the effects of our anti-takeover provisions.

ITEM 3.

QUANTITATIVE AND QUALITATIVE DISCLOSURE ABOUT MARKET RISK

Interest Rate Risk

We have investments in commercial paper, U.S. Government and agency securities, corporate bonds and other debt securities. As a result, we are exposed to potential loss from market risks that may occur as a result of changes in interest rates, changes in credit quality of the issuer or otherwise.

We generally place our marketable security investments in high quality credit instruments, as specified in our investment policy guidelines. A hypothetical 100 basis point increase in interest rates would result in an approximate $431,000 decrease in the fair value of our investments as of December 31, 2008. We believe, however, that the conservative nature of our investments mitigates our interest rate exposure, and our investment policy limits the amount of our credit exposure to any one issue, issuer (with the exception of U.S. agency obligations) and type of instrument. We do not expect any material loss from our marketable security investments and therefore believe that our potential interest rate exposure is limited. We intend to hold the majority of our investments to maturity, in accordance with our business plans.

ITEM 4.

CONTROLS AND PROCEDURES

The Company’s management, with the participation of the principal executive officer and the principal financial officer, has evaluated the effectiveness of the Company’s disclosure controls and procedures (as defined in Rules 13a-15(e) or 15d-15(e) under the Securities Exchange Act of 1934, as amended (the “Exchange Act”)) as of the end of the period covered by this report. Based on such evaluation, the chief executive officer and principal financial officer have concluded that, as of the end of such period, the Company’s disclosure controls and procedures were effective in ensuring that information required to be disclosed by the Company in the reports that it files or submits under the Exchange Act is recorded, processed, summarized and reported, on a timely basis, and is accumulated and communicated to the Company’s management, including the Company’s chief executive officer and the Company’s principal financial officer, as appropriate to allow timely decisions regarding required disclosure.

There was no change in the Company’s internal control over financial reporting that occurred during the period covered by this Quarterly Report on Form 10-Q that has materially affected, or is reasonably likely to materially affect, the Company’s internal control over financial reporting.
