NOTES TO FINANCIAL STATEMENTS
(UNAUDITED)

     The financial statements included in this report have been prepared, without audit, pursuant to the rules and regulations of the Securities and Exchange Commission. Certain information and footnote disclosures, normally included in financial statements prepared in accordance with U.S. generally accepted accounting principles, have been condensed or omitted pursuant to such rules and regulations. These financial statements should be read in conjunction with the audited financial statements and the related notes included in our Annual Report on Form 10-K for the fiscal year ended December 31, 2005.

     In the opinion of our management, any adjustments contained in the accompanying unaudited financial statements as of and for the three and six months ended June 30, 2006 and 2005 are of a normal recurring nature, except for the adjustments required to implement FASB Statement No. 123(R), and are necessary to present fairly our financial position, results of operations and cash flows. Interim results are not necessarily indicative of results for the full fiscal year.

1. Organization

     Avalon Pharmaceuticals, Inc. (“Avalon,” or the “Company”), was incorporated on November 10, 1999, under the laws of the state of Delaware. The Company is a biopharmaceutical company focused on the discovery and development of small molecule therapeutics for the treatment of cancer.

2. Summary of Significant Accounting Policies

Use of Estimates

     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 amounts reported in the financial statements and accompanying notes. Actual results could differ from those estimates.

Cash and Cash Equivalents

     The Company considers all highly liquid investments with a maturity of three months or less when purchased to be cash equivalents. Cash equivalents consist primarily of money market funds and commercial paper. The Company maintains cash balances with financial institutions in excess of insured limits. The Company does not anticipate any losses with such cash balances.

Marketable Securities

     Marketable securities consist primarily of corporate debt securities with various maturities. Management classifies the Company’s marketable securities as available-for-sale. Such securities are stated at market value, with the unrealized gains and losses included as accumulated other comprehensive income (loss). Realized gains and losses and declines in value judged to be other-than-temporary on securities available for sale, if any, are included in operations. A decline in the market value of any available-for-sale security below cost that is deemed to be other-than-temporary results in a reduction in fair value. The impairment is charged to earnings, and a new cost basis for the security is established. Dividend and interest income are recognized when earned. The cost of securities sold is calculated using the specific identification method.

Revenue Recognition

     Revenues are recognized when there is persuasive evidence that an arrangement exists, delivery has occurred, the price is fixed and determinable, and collection is reasonably assured. Payments received in advance of work performed are recorded as deferred revenue and recognized ratably over the performance period. Milestone payments are recognized as revenue in an amount commensurate with the level of effort expended when the milestones are achieved, contract partner acknowledges completion of the milestone, no further performance obligations exist as defined in the agreements, collection is reasonably assured and substantive effort was necessary to achieve the milestone. During the first six months of 2006, the Company recognized revenue from the amortization of up-front payments, work performed and expenses incurred on its collaboration agreements.

     Following a review of our collaboration agreements, we have determined that we prematurely recorded an aggregate of $535,000 of revenue in prior quarters under our agreement with MedImmune. An adjustment to reduce revenue by $535,000 was made in the second quarter of 2006 to reflect properly total revenue recorded through June 30, 2006 under this agreement.

Research and Development Costs

     The Company expenses its research and development costs as incurred.

Restricted Cash and Investments

     In accordance with the terms of a financing arrangement with the Maryland Industrial Development Financing Authority (MIDFA) and Manufacturers and Traders Trust Company (M&T Bank), in order to finance the build out of the Company’s corporate headquarters and research facility located in Germantown, Maryland, the Company established an investment account which is pledged as collateral for a letter of credit. The issuer of the letter of credit, M&T Bank, maintains the investment account. M&T Bank’s security interest in the account cannot exceed the minimum required cash collateral amount, which as of June 30, 2006, was defined as an adjusted market value of $5.5 million. This collateral agreement defines adjusted market value as the product of the fair market value of each permitted investment by a defined percentage ranging from 60% to 100%, depending on the nature of the permitted investment. The minimum cash collateral amount automatically decreases each April 1 as specified in the collateral agreement.

Comprehensive Income

     SFAS No. 130,Reporting Comprehensive Income,requires the presentation of comprehensive income or loss and its components as part of the financial statements. For the six months ended June 30, 2006 and 2005, the Company’s net loss plus its unrealized gains (losses) on available-for-sale securities reflects comprehensive income (loss).

Stock-Based Compensation

     Prior to January 1, 2006, the Company accounted for its stock-based compensation plans under the recognition and measurement provisions of Accounting Principles Board Opinion No. 25, “Accounting for Stock Issued to Employees” (“Opinion 25”), and related Interpretations, as permitted by FASB Statement No. 123,” “Accounting for Stock-Based Compensation” (“Statement 123”). Effective January 1, 2006, the Company adopted the fair value recognition provisions of FASB Statement No. 123(R), “Share-Based Payment” (“Statement 123(R)”), using the modified-prospective-transition method.

     Under the modified-prospective-transition method, compensation cost recognized in the second quarter of fiscal 2006 includes: (a) compensation cost for all share-based payments granted prior to but not yet vested as of January 1, 2006, based on the grant date fair value estimated in accordance with the original provisions of Statement 123, and (b) compensation cost for all share-based payments granted subsequent to January 1, 2006, based on the grant-date fair value estimated in accordance with the provisions of Statement 123(R). Results for prior periods have not been restated. The adoption of Statement 123(R) has no impact on the cash flows from operating or financing activities.

     The following table illustrates the effect on net loss and net loss per share if the Company had applied the fair value recognition provisions of Statement 123(R) to stock-based employee compensation for the three- and six-month periods ended June 30, 2005. The reported and pro forma net loss and net loss per share for the three- and six-month periods ended June 30, 2006 are the same because stock-based compensation expense is calculated under the provisions of Statement 123(R). The amounts for the three-month period ended June 30, 2006 are included in the table below only to provide net loss and net loss per share for a comparative presentation to the period of the previous year.

Net loss per share:
Basic and diluted — as reported	$	(0.44	)	$	(33.56	)	$	(0.94	)	$	(103.92	)
Basic and diluted — pro forma	$	(0.44	)	$	(33.20	)	$	(0.94	)	$	(103.73	)

     Pro forma information regarding net loss and net loss per share is required by Statement 123 and, in periods prior to January 1, 2006, had been determined as if the Company has accounted for its employee stock options under the fair value method. The fair value of each option grant is estimated on the date of grant using the Black-Scholes option-pricing fair value model. The following weighted-average assumptions were used for options granted in three and six months ended June 30, 2006 and a discussion of our methodology for developing each of the assumptions used in the valuation model follows:

	Three Months Ended			Six Months Ended
	June 30, 2006			June 30, 2006
Dividend yield		0.00	%		0.00	%
Expected volatility		67.30	%		66.32	%
Risk-free interest rate		4.86	%		4.71	%
Expected life of the option term (in years)		6.0			6.0
Forfeiture rate		2.68	%		2.68	%

Dividend Yield—The Company has never declared or paid dividends and has no plans to do so in the foreseeable future.

Expected Volatility—Volatility is a measure of the amount by which a financial variable such as a share price has fluctuated (historical volatility) or is expected to fluctuate (expected volatility) during a period. Due to the Company’s limited trading history, there is inadequate data to calculate historical volatility of our stock. The Company has used an average volatility of similar companies in the pharmaceutical industry. This volatility has averaged 67.3%, with a high and low value of 94.0% and 42%, respectively.

Risk-Free Interest Rate—This is the U.S. Treasury rate for the week of each option grant during the quarter having a term that most

Page 6

closely resembles the term of the option.

Expected Life of the Option Term—This is the period of time that the options granted are expected to remain unexercised. Options granted during the quarter have a maximum term of ten years. The Company has adopted SAB 107’s simplified method for estimating the expected term of stock options.

Forfeiture Rate—This is the estimated number of stock options granted that are expected to be forfeited or cancelled on an annual basis before becoming fully vested. The Company estimates the forfeiture rate based on past turnover data.

     The Company accounts for equity instruments issued to non-employees in accordance with Emerging Issues Task Force 96-18, “Accounting for Equity Instruments that are Issued to other than Employees for Acquiring, or in Conjunction with Selling, Goods, or Services”. For the six months ended June 30, 2006, compensation expense of $9,000 was recognized for the issuance of stock and stock options to non-employees.

Stock Compensation Plans

     The Company adopted the Avalon Pharmaceuticals, Inc. 1999 Stock Incentive Plan (the “1999 Plan”) to provide for the granting of stock awards, such as stock options, restricted common stock, and stock appreciation rights to employees, directors and other individuals as determined by the Board of Directors. The Company has reserved 624,143 shares of common stock to accommodate the exercise of options granted under the 1999 Plan.

     The Company terminated the 1999 Plan as to future awards effective upon the closing of the Company’s initial public offering in October 2005.

     Effective upon the closing of the Company’s initial public offering in October 2005, the Company adopted the Avalon Pharmaceuticals, Inc. 2005 Omnibus Long-Term Incentive Plan (the “2005 Plan”) to provide for the granting of stock awards, such as stock options, restricted common stock, stock units, dividend equivalent rights, stock appreciation rights and unrestricted common stock, and other performance and annual incentive awards to employees, directors and other individuals as determined by the Board of Directors. The Company reserved 989,738 shares of common stock to accommodate the exercise of options granted under the 2005 Plan.

     In June 2006, the 2005 Plan was amended and restated to increase the number of shares of Common Stock available for grants and awards under the 2005 Plan by 591,844 shares to a total of 1,581,582 shares.

     Generally, stock options are granted with an exercise price that equals the fair market value of the Company’s common stock on the grant date. Options typically have a life of ten years and vest over periods ranging from six months to five years. Options generally expire 90 days after an employee terminates employment with the Company.

     Shares of common stock issued to non-employee directors, as part of their annual director compensation, for the three- and six-month periods ended June 30, 2006 were 5,544 and 11,471, respectively. The fair market value of these shares, on the date of grant, was approximately $27,000 and $54,900, respectively.

     The total intrinsic value of stock options exercised during the three- and six-month periods ended June 30, 2006 was approximately $11,000 and $40,000, respectively. The weighted-average grant-date fair value of equity awards granted during the three- and six-month periods ended June 30, 2006 was $2.94 and $2.89, respectively. The total fair value of stock options which vested during the three- and six-month periods ended June 30, 2006 was approximately $360,000 and $1.2 million, respectively. There were 927,017 fully vested stock options outstanding at June 30, 2006. These stock options had a weighted average remaining life of 6.99 years.

Exercisable at June 30, 2006		927,017		$	4.36		6.99	$	254

     Cash received from the exercise of stock options under all share-based payment arrangements for the three months ended June 30, 2006 was $8,000. Due to the valuation allowance on all deferred tax assets, the Company recorded no tax benefit for options exercised during the three months ended June 30, 2006. As of June 30, 2006, there was approximately $669,000 of total unrecognized compensation costs related to nonvested employee stock options. That cost is expected to be recognized over a weighted average period of 2.94 years.

Basic and Diluted Net Loss Attributable to Common Stockholders Per Common Share

     Basic net loss attributable to common stockholders per common share excludes dilution for potential common stock issuances and is computed by dividing net loss attributable to common stockholders by the weighted-average number of common shares outstanding for the period. Diluted net loss attributable to common stockholders per common share reflects the potential dilution that could occur if securities or other contracts to issue common stock were exercised or converted into common stock. Mandatorily redeemable convertible preferred stock, stock options, and warrants were not considered in the computation of diluted net loss attributable to common stockholders per common share for the periods presented, as their effect is antidilutive.

3. Common Stock

     In February 2006, the Company raised $7.25 million through a private placement of 1,666,666 shares of its common stock to nine institutional investors. The proceeds from this financing will be used to expand the Company’s internal oncology drug discovery programs. Offering expenses of $70,000 were recorded to additional capital.

4. Related Party Transactions

     The Company paid two members of the board of directors consulting fees totaling $62,100 and $65,850 for the six months ended June 30, 2006 and 2005, respectively.

     On December 1, 2005, Avalon entered into a contract to lease certain unused equipment to NeoDiagnostix upon the approval of the transaction by independent members of the Company’s board of directors. Kenneth C. Carter, Ph.D., the Company’s President, Chief Executive Officer and Director, is a director and minority shareholder in NeoDiagnostix, a privately held company focused on providing oncology diagnostic testing on a fee-for-service basis.

5. Income Taxes

     For the three- and six-month periods ended June 30, 2006, there is no current provision for income taxes and the deferred tax benefit has been entirely offset by valuation allowances. The difference between the amounts of income tax benefit that would result from applying domestic federal statutory income tax rates to the net loss and the net deferred tax assets is related to certain nondeductible expenses, state income taxes, and the change in the valuation allowance.

6. Debt

     In August 2005, the Company entered into a modification agreement with MIDFA and M&T Bank under its letter of credit agreement pursuant to which M&T Bank agreed to waive the Company’s compliance with all financial covenants contained in the Company’s letter of credit with M&T Bank guaranteeing the Company’s development bond financing obligations to MIDFA. The minimum tangible net worth, minimum restricted cash balance and minimum ratio of current assets to current liabilities financial covenants were waived until April 1, 2006. In exchange for this waiver, the Company increased by $500,000 the cash collateral amount held as restricted cash under the letter of credit to approximately $6.3 million. On April 1, 2006 the waivers expired and the cash collateral amount held as restricted cash was reduced to approximately $5.5 million. The Company is in compliance with all financial covenants contained in the Company’s letter of credit.

Item 2. Management’s Discussion and Analysis of Financial Condition and Results of Operations

     The following discussion and analysis of our results of operations, financial condition and liquidity and capital resources should be read in conjunction with our unaudited consolidated financial statements and related notes contained in this Quarterly Report onForm 10-Q, as well as the audited financial statements and related notes for the fiscal year ended December 31, 2005 and “Management’s Discussion and Analysis of Financial Condition and Results of Operations,” contained in our Annual Report onForm 10-K, for the fiscal year ended December 31, 2005.

Overview

     We are a biopharmaceutical company focused on the discovery and development of small molecule therapeutics. Our pipeline of drug candidates includes our lead candidate, AVN944. AVN944 is an oral, small molecule drug candidate that was discovered by Vertex Pharmaceuticals Incorporated and that we licensed from Vertex in February 2005. AVN944 is currently in early stage clinical development for the treatment of hematological cancers. We seek to discover and develop novel therapeutics through the use of a comprehensive, innovative and proprietary suite of technologies based upon large-scale gene expression analysis, which we call AvalonRx^®.

     Since we commenced business in January 2000, our operations have consisted primarily of developing AvalonRx^®, utilizing our technology to seek to discover and develop novel cancer therapeutics and the in-license and subsequent development of AVN944. In that period, we have generated limited revenue from collaborative partners, and have had no revenue from product sales. Our operations have been funded principally through the offering of equity securities and debt financings.

     We have never been profitable and, as of June 30, 2006, we had an accumulated deficit of $94.6 million. We had net losses of $9.0 million for the six months ended June 30, 2006 and net losses of $19.3 million for the year ended December 31, 2005. We expect to incur significant and increasing operating losses for the foreseeable future as we advance our drug candidates from discovery through preclinical testing and clinical trials and seek regulatory approval and eventual commercialization. In addition to these increasing research and development expenses, we expect general and administrative costs to increase as we add personnel. We will need to generate significant revenues to achieve profitability, and we may never do so.

Financial Operations Overview
Revenue

     We have not generated any revenue from sales of commercial products and do not expect to generate any product revenue for the foreseeable future. To date, our revenue has consisted of collaboration revenue.

     Collaboration Revenue.Since inception, we have generated revenue solely in connection with our collaboration and pilot study agreements. Our collaborations with MedImmune and Novartis include upfront payments, research funding, and payments for the achievement of certain discovery and development related milestones. During the third quarter of 2005, we began to recognize revenue under our collaboration with MedImmune which was signed in June 2005. As of June 30, 2006, we have not recognized any revenue under our collaboration with Novartis.

Research and Development Expense

     Research and development expense consists of expenses incurred in connection with developing and advancing our drug discovery technology and identifying and developing our drug candidates. These expenses consist primarily of salaries and related expenses, the purchase of laboratory supplies, access to data sources, facility costs, costs for preclinical development and expenses related to our in-license of AVN944. We charge all research and development expenses to operations as incurred.

     We expect our research and development costs to be substantial and to increase as we advance AVN944 through clinical trials and move other drug candidates into preclinical testing and clinical trials. Based on the results of our preclinical studies, we expect to selectively advance some drug candidates into clinical trials. We anticipate that we will select drug candidates and research projects for further development on an ongoing basis in response to their preclinical and clinical success and commercial potential. With regard to AVN944, we initiated U.S. Phase I clinical trials of AVN944 in cancer patients in January 2006.

General and Administrative

     General and administrative expense consists primarily of salaries and related expenses for personnel in administrative, finance, business development and human resource functions. Other costs include legal costs of pursuing patent protection of our intellectual property, unallocated facility costs and professional fees for legal services. We anticipate increases in general and administrative expense relating to operating as a public company. These increases will likely include legal fees, accounting fees and directors’ and officers’ insurance premiums as well as fees for investor relations services.

Critical Accounting Policies and Significant Judgments and Estimates

Stock-Based Compensation

     In December 2004, the Financial Accounting Standards Board (“FASB”) issued Statement of Financial Accounting Standards (“SFAS”) No. 123, revised 2004, or SFAS 123(R), “Share-Based Payment ” SFAS 123(R) supersedes Accounting Principles Board (“APB”) Opinion No. 25, “Accounting for Stock Issued to Employees” (“APB 25”), and requires companies to recognize compensation expense, using a fair-value based method, for costs related to share-based payments, including those made pursuant to stock option and employee stock purchase plans.

     We adopted SFAS 123(R) on January 1, 2006 using the modified prospective transition method, which requires that stock-based compensation cost is recognized for all awards granted, modified or settled after the effective date as well as for all awards granted to employees prior to the effective date that remain unvested as of the effective date. Prior to the adoption, we disclosed such costs on a pro forma basis in the notes to our financial statements. In accordance with the modified prospective method, the financial statements for prior periods have not been restated to reflect the impact of FAS 123R.

Page 9

     For and six months ended June 30, 2006, we recorded approximately $1.2 million of stock-based compensation expenses, of which $367,000 was included in research and development expense and $861,000 was included in general and administrative expense. Since we continue to operate in a net loss, the adoption of SFAS 123(R) had no impact for tax-related effects on cash flow from operations and cash flow from financing activities for the six months ended June 30, 2006. As of June 30, 2006, unamortized stock-based compensation expenses of approximately $669,000 remains to be recognized over a weighted-average period of approximately 3 years. We amortize stock-based compensation expenses on a straight-line ratable basis over the vesting period.

     We estimated the fair value of stock options granted during the three months ended June 30, 2006 using the Black-Scholes option pricing model. The assumptions used under this model are as follows: (i) expected term of 6 years based on the simplified method for estimating the expected term of stock options; (ii) expected volatility of 67.3% based on historical and peer volatility data; (iii) weighted average risk-free interest rate of 4.86% based on the U.S. Treasury yield curve in effect at the time of grant for periods corresponding with the expected term of the option; and (iv) expected dividend yield of zero percent. In addition, under SFAS 123(R), the fair value of stock options granted is recognized as expense over the service period, net of estimated forfeitures. Based on historical data, we calculated a 2.68% annual forfeiture rate, which we believe is a reasonable assumption. However, the estimation of forfeitures requires judgment, and to the extent actual results or updated estimates differ from our current estimates, such amounts will be recorded as a cumulative adjustment in the period estimates are revised.

     The Black-Scholes option pricing model requires the input of highly subjective assumptions. Because our 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 may not provide a reliable single measure of the fair value of our employee stock. In addition, management will continue to assess the assumptions and methodologies used to calculate estimated fair value of share-based compensation. Circumstances may change and additional data may become available over time, which result in changes to these assumptions and methodologies, and which could materially impact our fair value determination.

Results of Operations

Three Months Ended June 30, 2006 and 2005

     Revenue.Total revenues increased to $417,000, for the three months ended June 30, 2006, compared to no revenue for the three months ended June 30, 2005. This revenue was primarily attributable to MedImmune with a small portion of revenue attributable to our collaboration agreement with the University of Louisville. Following a review of our collaboration agreements, we have determined that we prematurely recorded an aggregate of $535,000 of revenue in prior quarters under our agreement with MedImmune. An adjustment to reduce revenue by $535,000 was made in the second quarter of 2006 to reflect properly total revenue recorded through June 30, 2006 under this agreement. This adjustment had no impact on cash received from MedImmune under the terms of the agreement.

     Research and Development.Research and development expenses increased by $717,000, or 27%, to $3.3 million for the three months ended June 30, 2006 from $2.6 million for the same period in 2005. The increase in research and development expenses was primarily attributable to compensation expense related to the issuance of stock options, an increase in outside services costs related to our AVN944 drug candidate and an increase in lab supplies expense related, in part, to our collaboration agreement with MedImmune.

     Research and development expenses consist of direct costs which include salaries and related costs of research and development personnel, and the costs of consultants, materials and supplies associated with research and development projects. Indirect research and development costs include facilities, depreciation, patents and other indirect overhead costs.

     During the remainder of 2006, and thereafter, research and development expenses will increase substantially as we continue Phase I clinical studies for our AVN944 drug candidate.

     General and Administrative.General and administrative expenses increased by $510,000 or 40% to $1.8 million for the three months ended June 30, 2006, compared to $1.3 million for the three months ended June 30, 2005. The increase is attributable to compensation expense related to the issuance of stock options, accrued bonuses for executives and staff, and other expenses from operating as a public company.

     Interest Income.Interest income increased by $252,000 or 304%, to $335,000 for the three months ended June 30, 2006, compared to $83,000 for the three months ended June 30, 2006. The increase in interest income is a result of interest earned on proceeds from issuance of common stock, including proceeds from our initial public offering, and higher average interest rates.

     Interest Expense.Interest expense decreased by $109,000, or 34%, to $204,000 for the three months ended June 30, 2006, compared to $313,000 for the three months ended June 30, 2005. The decrease in interest expense was primarily related to the conversion of our outstanding convertible notes into common stock at the close of our initial public offering in October 2005, and lower balances on our long term debt. This decrease was offset, in part, by higher average interest rates on our long term debt and development bond financing.

     Other Income.Other income was $156,000 for the three months ended June 30, 2006, compared to $157,000 for the three months ended June 30, 2005. All of our other income during the period consisted of income from subletting part of our facility and the provision of shared services to our subtenants.

Six Months Ended June 30, 2006 and 2005

     Revenue.Total revenues increased to $956,000, for the six months ended June 30, 2006, compared to $0 for the six months ended June 30, 2005. Substantially all 2006 revenues are related to our collaboration agreement with MedImmune, Inc. A small portion of revenue was attributable to our collaboration agreement with the University of Louisville. Following a review of our collaboration agreements, we have determined that we prematurely recorded an aggregate of $535,000 of revenue in prior quarters under our agreement with MedImmune. An adjustment to reduce revenue by $535,000 was made in the second quarter of 2006 to reflect properly total revenue recorded through June 30, 2006 under this agreement. This adjustment had no impact on cash received from MedImmune under the terms of the agreement.

Page 10

     We expect that collaborative research and development revenues will continue to be a significant source of our total revenue and entered into an additional collaboration agreement with Novartis Institutes for Biomedical Research, Inc. during the third quarter of 2005 that could be material to our business. No revenue was recognized under the Novartis agreement during the quarter.

     Research and Development.Research and development expenses decreased $3.5 million, or 35%, to $6.5 million for the six months ended June 30, 2006 from $10.0 million for the same period in 2005. The decrease in research and development expenses was primarily attributable to the inclusion in the prior year period of an upfront payment of $5.0 million to Vertex for the in-license of AVN944. This decrease was offset by compensation expense related to the issuance of stock options, an increase in outside services costs related to our AVN944 drug candidate and an increase in lab supplies expense related, in part, to our collaboration agreement with MedImmune.

     General and Administrative.General and administrative expenses increased by $1.6 million or 65%, to $4.0 million for the six months ended June 30, 2006 compared to $2.5 million for the six months ended June 30, 2005. The increase was primarily attributable to compensation expense related to the issuance of stock options, accrued bonuses for executives and staff, new hires and salary increases, increase in franchise taxes and other expenses directly related to operating as a public company. These increases were offset, in part, by a decrease in professional fees and other outside services expenses for the six months ended June 30, 2006.

     Interest Income.Interest income increased by $508,000, or 313%, to $670,000 for the six months ended June 30, 2006 compared to $163,000 for the six months ended June 30, 2005. The increase in interest income is a result of interest earned on proceeds from issuance of common stock, including proceeds from our initial public offering, and higher average interest rates.

     Interest Expense.Interest expense decreased by $177,000, or 29%, to $424,000 for the six months ended June 30, 2006 compared to $602,000 for the six months ended June 30, 2005. The decrease in interest expense was primarily related to the conversion of our outstanding convertible notes into common stock at the close of our initial public offering in October 2005 and lower balances on our long term debt. This decrease was offset, in part, by higher average interest rates on our long term debt and development bond financing.

     Other Income.Other income increased by $124,000, or 55%, to $346,000 for the six months ended June 30, 2006 compared to $222,000 for the six months ended June 30, 2005. All other income during the period consisted of income from subletting part of our facility and the provision of shared services to our subtenants.

Liquidity and Capital Resources

     Our primary cash requirements are to:

• fund our research and development programs;

• obtain regulatory approvals;

• prosecute, defend and enforce any patent claims and other intellectual property rights;

• fund general corporate overhead; and

• support our debt service requirements and contractual obligations.

     Our cash requirements could change materially as a result of the progress of our research and development and clinical programs, licensing activities, acquisitions, divestitures or other corporate developments.

     We have incurred operating losses since our inception and historically have financed our operations principally through public stock offerings, private placement of equity securities, strategic collaborative agreements that include research and development funding, development milestones, and investment income.

     In evaluating alternative sources of financing we consider, among other things, the dilutive impact, if any, on our stockholders, the ability to leverage stockholder returns through debt financing, the particular terms and conditions of each alternative financing arrangement and our ability to service our obligations under such financing arrangements.

     As of June 30, 2006, we had cash, cash equivalents and marketable securities of approximately $26.8 million. Of this amount, $5.5 million is currently held in a restricted account to serve as collateral for our long-term debt. Our funds are currently invested in investment grade and United States government securities.

Sources and Uses of Cash

     Operating Activities.Net cash used in operating activities for the six months ended June 30, 2006 was $6.1 million, compared to $6.9 million for the same period in fiscal 2005. During the first six months of fiscal year 2006, our net loss of $9.0 million was reduced by non-cash charges of $2.9 million, primarily associated with the issuance of stock options, depreciation and amortization and reduction in our net operating assets and liabilities. Net operating assets and liabilities declined due to a $731,000 decrease in accounts payable and accrued liabilities, of which $718,000 was directly related to payment of 2005 year end performance bonuses. This decrease was offset, in part, by a $598,000 increase in accounts receivable and other assets.

     Investing Activities.Net cash used in investing activities for the six months ended June 30, 2006 was $4.5 million, compared to $5.1 million of cash provided by investing activities during the same period in 2005. Cash used in investing activities represents the amount used to purchase marketable securities, net of proceeds from the sale and maturity of marketable securities.

     Financing Activities.Net cash provided by financing activities for the six months ended June 30, 2006 was $5.2 million, compared to $2.9 million for the same period in 2005. During the first six months of 2006, $7.3 million was raised from issuance of common stock. This amount was offset by $1.8 million repayments on debt.

     Credit Arrangements

     In April 2003, we entered into a series of agreements with the Maryland Industrial Development Financing Authority, or MIDFA, and Manufacturers and Traders Trust Company, or M&T Bank, in order to finance improvements to our corporate office and research facility located in Germantown, Maryland. MIDFA sold development bonds in the amount of $12.0 million. The proceeds of the bond sale were put in trust to reimburse us for the costs we incurred for improvements to our facility. We are required to repay the trust $1.2 million annually for these borrowings. The borrowing bears interest at a variable rate and matures on April 8, 2013. The weighted-average interest rate during the six months ended June 30, 2006 and 2005 was 4.92% and 2.99% respectively.

     In connection with the development bond financing, we entered into an agreement with M&T Bank to issue the trustee an irrevocable letter of credit to provide payment of the principal and interest of the bonds. The amount of the letter of credit changes annually, as principal payments are made. As of June 30, 2006, that amount is $8,538,082, consisting of $8.4 million of principal and $138,082 in interest, computed at 50 days at an assumed maximum rate of interest of 12% per annum. The letter of credit expires the earlier of April 8, 2008, or the date the bonds have been paid in full. In consideration of the letter of credit, we have granted M&T Bank a security interest in certain facility improvements, equipment and cash collateral held as restricted cash. In August 2005 we entered into a modification agreement with M&T Bank and MIDFA pursuant to which M&T Bank agreed to waive our compliance with the financial covenants contained in the letter of credit until April 2006 in exchange for increasing the amount of cash collateral held as restricted cash to $6.3 million. On April 1, 2006 the waiver expired and the cash collateral amount held as restricted cash was reduced to $5.5 million. The Company is in compliance with all financial covenants contained in the Company’s letter of credit.

     In June 2002, we entered into an equipment line of credit with General Electric Capital Corporation that provided for borrowings of up to $5.0 million. In 2003, the line of credit was increased to allow for an additional $2.0 million in borrowings. During 2002 and 2003 a total of $5.6 million was borrowed by us under the equipment line of credit. No draws were made during 2004 and the availability of the line of credit has lapsed. Each draw has been treated as a separate promissory note bearing interest between 7.09% to 8.68% over 36- to 48-month terms. The line of credit is secured by the applicable equipment, fixtures, and personal property financed by the line of credit. In connection with draws under the line of credit, the lender received warrants to purchase a total of 39,306 shares of our Series B preferred stock at an exercise price of $3.53, which subsequently automatically converted into warrants to purchase 8,666 shares of common stock at an exercise price of $28.24 per share in connection with the closing of our initial public offering. At June 30, 2006, roughly $760,000 in borrowings remained outstanding under this line of credit.

Operating Capital and Capital Expenditure Requirements

     We expect to continue to incur substantial operating losses in the future. We will not receive any product revenue until a drug candidate has been approved by the FDA or similar regulatory agencies in other countries and successfully commercialized. We currently anticipate that our cash, cash equivalents and marketable securities, together with cash flow generated from our collaborations, will be sufficient to fund our operations at least through the next eighteen months. However, we will need to raise substantial additional funds to continue our operations and bring future products to market. We cannot be certain that any of our programs will be successful or that we will be able to raise sufficient funds to complete the development and commercialization of any of our drug candidates currently in development, should they succeed. Additionally, we plan to continue to evaluate in-licensing and acquisition opportunities to gain access to new drugs or drug targets that would fit with our strategy. Any such transaction would likely increase our funding needs in the future.

     Our future funding requirements will depend on many factors, including but not limited to:

• the size and complexity of our research and development programs;

• the scope and results of our preclinical testing and clinical trials;

• continued scientific progress in our research and development programs;

• the time and expense involved in seeking regulatory approvals;

• competing technological and market developments;

• acquisition, licensing and protection of intellectual property rights; and

• the cost of establishing manufacturing capabilities and conducting commercialization activities.

          Until we can generate a sufficient amount of product revenue to finance our cash requirements, which we may never do, we expect to finance future cash needs primarily through public or private equity offerings, debt financings or strategic collaborations. If we are successful in raising additional funds through the issuance of equity securities, investors likely will experience dilution, or the equity securities may have rights, preferences or privileges senior to those of the holders of our common stock. If we raise funds through the issuance of debt securities, those securities would have rights, preferences and privileges senior to those of our common stock. We do not know whether additional funding will be available on acceptable terms, or at all. If we are not able to secure additional funding when needed, we may have to delay, reduce the scope of, or eliminate one or more of our clinical trials or research and development programs. In addition, we may have to partner one or more of our drug candidate programs at an earlier stage of development, which would lower the economic value of those programs to our company.

Item 3. Quantitative and Qualitative Disclosures About Market Risk

     We are exposed to market risk from changes in interest rates. At June 30, 2006, we had $8.4 million of obligations which were subject to variable rates of interest under our development bond financing with MIDFA. If market interest rates increased 1% from the rate at June 30, 2006, our annual interest expense would increase approximately $84,000, assuming that obligations subject to variable interest rates remained constant.

     In addition, the value of our portfolio of cash equivalents and investments is subject to market risk from changes in interest rates.

     The primary objective of our investment activities is to preserve our capital for the purpose of funding operations while at the same time maximizing the income we receive from our investments without significantly increasing risk. To achieve these objectives, our investment policy allows us to maintain a portfolio of cash equivalents and investments in a variety of securities, including commercial paper, money market funds and corporate debt securities. As of June 30, 2006, we had cash and cash equivalents, short-term and long-term investments and restricted cash of $26.8 million as follows:

Cash and cash equivalents	$4.4 million
Short-term investments	$16.1 million
Long-term investments	$0.8 million
Restricted cash	$5.5 million

     We maintain an investment portfolio of investment grade government agency notes and corporate bonds. The securities in our investment portfolio are not leveraged, are classified as available-for-sale and are, due to their predominantly short-term nature, subject to minimal interest rate risk. We currently do not hedge interest rate exposure on our investment portfolio. As of June 30, 2006, securities totaling $16.1 million mature in the next 12 months and $.8 million mature after June 30, 2007. While we do not believe that an increase in market rates of interest would have any significant negative impact on the realizable value of our investment portfolio, changes in interest rates affect the investment income we earn on our investments and, therefore, impact our cash flow and results of operations.

     We have operated in the United States and all revenues to date have been received in U.S. dollars. Accordingly, we have not had any material exposure to foreign currency rate fluctuations.

Item 4. Controls and Procedures

     Disclosure Controls and Procedures:Under the supervision and with the participation of our management, including our Chief Executive Officer and our Chief Financial Officer, we have evaluated the effectiveness of our disclosure controls and procedures, as of June 30, 2006 (the “Evaluation Date”). Based on that evaluation, our Chief Executive Officer and Chief Financial Officer have concluded that, as of the Evaluation Date, our disclosure controls and procedures were effective.

     Changes in Internal Control over Financial Reporting:There have been no changes in our internal control over financial reporting during the quarter ended on the Evaluation Date that has materially affected, or is reasonably likely to materially affect, our internal control over financial reporting.
