EXHIBIT 99.1 REPORT OF INDEPENDENT AUDITORS The Board of Directors and Stockholders Discovery Laboratories, Inc. New York, New York We have audited the accompanying consolidated balance sheet of Discovery Laboratories, Inc. and subsidiary (a development stage company) as at December 31, 1996, and the related consolidated statements of operations, changes in stockholders' equity and cash flows for the two years ended December 31, 1996, and the period from May 18, 1993 (inception) to December 31, 1996. These financial statements are the responsibility of the Company's management. Our responsibility is to express an opinion on these financial statements based on our audits. We conducted our audits in accordance with generally accepted auditing standards. Those standards require that we plan and perform the audits to obtain reasonable assurance about whether the financial statements are free of material misstatement. An audit includes examining, on a test basis, evidence supporting the amounts and disclosures in the financial statements. An audit also includes assessing the accounting principles used and significant estimates made by management, as well as evaluating the overall financial statement presentation. We believe that our audits provide a reasonable basis for our opinion. In our opinion, the consolidated financial statements enumerated above present fairly, in all material respects, the financial position of Discovery Laboratories, Inc. and subsidiary at December 31, 1996 and the results of their operations and their cash flows for the two years ended December 31, 1996, and the period from May 18, 1993 (inception) to December 31, 1996 in conformity with generally accepted accounting principles.

DISCOVERY LABORATORIES, INC. AND SUBSIDIARY (A DEVELOPMENT STAGE COMPANY) NOTES TO FINANCIAL STATEMENTS (UNAUDITED WITH RESPECT TO INFORMATION AS OF JUNE 30, 1997 AND FOR THE SIX- MONTH PERIODS ENDED JUNE 30, 1997 AND JUNE 30, 1996) (NOTE A)--THE COMPANY AND BASIS OF PRESENTATION: Discovery Laboratories, Inc. (the "Company") was incorporated in Delaware on May 18, 1993 as MicroBio, Inc. The Company is a development stage company formed to license and develop pharmaceutical products to treat a variety of human diseases. The consolidated financial statements include the accounts of the Company and its 75% owned subsidiary Acute Therapeutics, Inc. (see Note G). Intercompany balances and transactions have been eliminated. No allocation of the subsidiary's net loss has been attributed to the minority interest since the accumulated losses exceed the minorities' common equity interest. In November 1996 the Company completed a private placement of its securities and received aggregate net proceeds of approximately $19,000,000 (see Note F). (NOTE B)--SUMMARY OF SIGNIFICANT ACCOUNTING POLICIES: [1] Cash and cash equivalents: The Company considers all highly liquid investments purchased with a maturity of three months or less to be cash equivalents. [2] Investments in United States Government obligations: The investments in United States Government obligations are comprised of securities which are available for sale and are recorded at fair value with any appreciation/depreciation recorded in the statement of operations. [3] Computer equipment: Computer equipment is recorded at cost. Depreciation is computed using the straight-line method over the useful lives of the assets (five years). [4] Licenses: Through March 1997 licenses were capitalized and were being amortized on a straight-line basis over their respective terms of 15 to 17 years. During the quarter ended June 30, 1997, the Company determined that since they will not pursue any alternative uses for the licenses, that all license costs would be written off as research and development costs. [5] Research and development: Research and development costs are charged to operations as incurred. [6] Use of estimates: The preparation of financial statements in conformity with generally accepted accounting principles requires management to make estimates and assumptions that affect the reported amounts of 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. [7] Long-lived assets: In accordance with Statement of Financial Accounting Standards No. 121, "Accounting for the Impairment of Long-Lived Assets and for Long-Lived Assets to be Disposed of", the Company records impairment losses

DISCOVERY LABORATORIES, INC. AND SUBSIDIARY (A DEVELOPMENT STAGE COMPANY) NOTES TO FINANCIAL STATEMENTS--(CONTINUED) on long-lived assets used in operations, including intangible assets, when events and circumstances indicate that the assets might be impaired and the undiscounted cash flows estimated to be generated by those assets are less than the carrying amounts of those assets. No such losses have been recorded. [8] Stock-based compensation: During 1996, the Company adopted Statement of Financial Accounting Standards, No. 123, "Accounting for Stock-Based Compensation" ("SFAS No. 123"). The provisions of SFAS No. 123 allow companies to either expense the estimated fair value of stock options or to continue to follow the intrinsic value method set forth in APB Opinion 25, "Accounting for Stock Issued to Employees" ("APB 25") but disclose the pro forma effects on net income (loss) had the fair value of the options been expensed. The Company has elected to continue to apply APB 25 in accounting for its employee stock option incentive plans. See Note H to the financial statements for further information. [9] Net loss per share: Pro forma net loss per share is computed based on the weighted average number of common shares outstanding for the periods adjusted to reflect the number of shares of Ansan Pharmaceuticals, Inc. common stock issuable to the common stockholders of the Company upon consummation of the merger (Note J). Common stock equivalents are not included in the calculation of net loss per share as the effect would be anti-dilutive. [10] Interim financial statements: In the opinion of management, the interim financial statements include all adjustments, consisting of normal recurring accruals, necessary for a fair presentation of the Company's financial position at June 30, 1997 and results of operations and cash flows for the six-month period ended June 30, 1997. The financial statements as of June 30, 1997 and for the six months ended June 30, 1997 are not necessarily indicative of the results that may be expected for the year ending December 31, 1997. [11] Recent accounting pronouncements: Recently issued accounting pronouncements concerning disclosure of information about capital structure, reporting comprehensive income and disclosure about segments of an enterprise and related information are not expected to have a material effect on the presentation of the Company's financial statements, the recent pronouncement on earnings per share provides a simplified method for computing loss per share and will require retroactive restatement when effective. (NOTE C)--EMPLOYMENT AGREEMENTS: An employment agreement with the Company's president provides for an annual salary of $175,000 through April 1999. Employment agreements with two executive officers provide for aggregate annual salaries of $295,000 through December 1999, subject to certain increases. (NOTE D)--INCOME TAXES: At June 30, 1997, the Company has available for federal income tax purposes net operating loss carryforwards of approximately $1,600,000 expiring through 2011, that may be used to offset future taxable income.

DISCOVERY LABORATORIES, INC. AND SUBSIDIARY (A DEVELOPMENT STAGE COMPANY) NOTES TO FINANCIAL STATEMENTS--(CONTINUED) The principal difference between the deficit accumulated during the development stage for financial reporting purposes and the net operating loss carryforward for tax purposes is primarily due to the write-off of the acquired research and development supplies and to certain general and administrative costs which are not currently deductible for tax purposes. The Company has provided a valuation reserve against the full amount of the deferred tax asset of $2,590,000 arising from net operating loss benefit of approximately $640,000, the research and development write-off of approximately $1,130,000 and general and administrative costs of approximately $820,000 since the likelihood of realization cannot be determined. The valuation reserve increased by approximately $1,223,000 and $7,000 for the years ended December 31, 1996 and December 31, 1995, respectively and approximately $1,360,000 for the six months ended June 30, 1997. Pursuant to Section 382 of the Internal Revenue Code, the utilization of this carryforward may be limited due to ownership changes which have occurred or may occur. (NOTE E)--LICENSE AGREEMENTS: [1] The Company entered into a license agreement with the Charlotte- Mecklenburg Hospital Authority for the use of the active compound in SuperVent, a therapy which the Company is clinically testing. The Company paid a license issue fee of $86,400 and has agreed to pay royalties on future sales and to pay future patent- related costs. The license expires upon expiration of the underlying patents. [2] The Company entered into a license agreement with the Wisconsin Alumni Research Foundation ("WARF") for the use of the patented compound ST-630 in the treatment of post-menopausal osteoporosis. The Company paid WARF an option fee of $25,000 in June 1996 and a license issue fee of $400,000 in October 1996 and is obligated to make future milestone payments aggregating $3,095,000 and pay royalties on future sales. The license expires upon expiration of the underlying patents. [3] See Note G[1] with respect to a sublicense agreement with Johnson & Johnson, Inc. (NOTE F)--PRIVATE PLACEMENT: Pursuant to a private placement memorandum, the Company offered for sale units, each unit consisting of 50,000 shares of Series A convertible preferred stock and 50,000 shares of common stock. Preferred stockholders have voting rights based upon the number of shares of common stock issuable upon conversion of the preferred shares. Each share of preferred stock is initially convertible at the option of the holders thereof into four shares of common stock of the Company. The conversion rate will be adjusted under certain circumstances as described in the private placement memorandum. From August 1996 through November 1996, the Company received net proceeds of approximately $19,000,000 for the sale of approximately 44 units. Paramount Capital, Inc. ("Paramount") acted as the placement agent for the offering and received a 9% commission plus a 4% nonaccountable expense allowance aggregating $2,860,332. The Company also issued to Paramount warrants to acquire 220,026 shares of Series A preferred stock at a price of $11 per share, through November 8, 2006 and warrants to acquire 220,026 shares of common stock at a price of $.25 per share, through November 8, 2006. The warrants contain certain anti-dilution provisions and may be exercised on a "net exercise" basis pursuant to a provision that does not require the payment of any cash to the Company.

DISCOVERY LABORATORIES, INC. AND SUBSIDIARY (A DEVELOPMENT STAGE COMPANY) NOTES TO FINANCIAL STATEMENTS--(CONTINUED) (NOTE G)--INVESTMENT IN ACUTE THERAPEUTICS, INC.: [1] Formation of Acute Therapeutics, Inc.: On October 28, 1996, the Company invested $7.5 million in a newly formed subsidiary, Acute Therapeutics, Inc. ("ATI"), in exchange for 600,000 shares of Series A convertible preferred stock of ATI, representing 75% of the outstanding voting securities of ATI following such transaction. Concurrently with the Company's investment in ATI, Johnson & Johnson, Inc. ("J & J"), Ortho Pharmaceuticals, Inc. (a wholly-owned subsidiary of J & J), and ATI entered into an agreement (the "J & J License Agreement") granting an exclusive license of KL4-Surfactant technology to ATI in exchange for certain license fees ($200,000 of which was paid in November 1996), milestone payments aggregating $2,750,000, royalties and 40,000 shares of ATI common stock. J & J contributed its KL4-Surfactant raw material inventory and manufacturing equipment to ATI in exchange for 2,200 shares of nonvoting Series B preferred stock of ATI having a $2.2 million liquidation preference and a $100 per share cumulative dividend. The inventory and equipment were valued at $2,200,000 (the value of the preferred shares issued to J & J) and were charged to expense as their intended use is for research and development activities. The Scripps Research Institute received 40,000 shares of common stock of ATI in exchange for its consent to the J & J License Agreement. The founders of ATI purchased an aggregate of 120,000 shares of ATI common stock for $.01 per share and were granted options to purchase an aggregate of 44,800 shares of common stock of ATI at an exercise price of $.01 per share vesting after a five-year term, subject to acceleration and 40,000 shares of common stock of ATI at an exercise price of $.32 per share vesting in April 1997. [2] Commitments: ATI entered into a four-year employment agreement with its President, Chief Executive Officer and Chairman of the Board of Directors providing for a base salary of $225,000 per year plus an initial sign-on bonus of $50,000 to be paid the first week of January 1997, plus certain incentive bonuses. ATI also entered into a three year employment agreement with an officer providing for an annual salary of $200,000 and various two-year consulting agreements providing for aggregate annual fees of $300,000 plus royalties on net commercial sales of licensed products sold by ATI or its sublicensees and an 18-month consulting agreement providing for monthly fees of $7,500. ATI leases its office and laboratory space pursuant to an operating lease requiring aggregate annual payments of approximately $67,000 through November 2001. [3] ATI stock option plan: ATI adopted the 1996 Stock Option/Stock Issuance Plan (the "ATI Plan") consisting of a Discretionary Option Grant program for employees and an Automatic Option Grant Program under which option grants will automatically be made at periodic intervals to eligible nonemployee directors to purchase shares of common stock, in either case at an exercise price equal to at least 85% of the fair market value of the common stock on the grant date. Under the Discretionary Option Grant program, options will be granted to employees either as incentive stock options or nonstatutory options and will vest over a specified period of time (generally three to five years) as determined by the ATI Board of Directors. ATI has reserved 234,800 shares of common stock for issuance under these plans. Options for 173,800 shares of common stock have been granted through January 1997.

DISCOVERY LABORATORIES, INC. AND SUBSIDIARY (A DEVELOPMENT STAGE COMPANY) NOTES TO FINANCIAL STATEMENTS--(CONTINUED) (NOTE H)--STOCK OPTIONS: In November 1996, the Company adopted its 1996 Stock Option/Stock Issuance Plan which includes three equity programs (the "Discovery Plan"). Under the Discretionary Option Grant Program, options to acquire shares of the Company's common stock may be granted to eligible persons who are employees, nonemployee directors, consultants and other independent advisors. Pursuant to the Stock Issuance Program, such eligible persons may be issued shares of the Company's common stock directly and under the Automatic Option Grant Program, eligible directors will automatically receive option grants at periodic intervals. The maximum number of shares of common stock which maybe issued over the term of plan shall not exceed 1,250,000. In July and August, 1996, options to purchase 100,000 shares of the Company's common stock were granted (all of which were immediately exercisable), with a weighted average exercise price of $.125 per share. Options to purchase 25,000 shares at $.10 per share were exercised in July 1996 and options to purchase 25,000 shares at $.20 per share were exercised in November 1996. The Company applies APB 25 in accounting for the Discovery Plan and the ATI Plan and, accordingly, recognizes compensation expense for the difference between the fair value of the underlying common stock and the exercise price of the option at the date of grant. The effect of applying SFAS No. 123 on pro forma net loss is not necessarily representative of the effects on reported net income or loss for future years due to, among other things, (1) the vesting period of the stock options and the (2) fair value of additional stock options in future years. Had compensation cost for the Company's stock option plans been determined based upon the fair value of the options at the grant date of awards under the plans consistent with the methodology prescribed under SFAS No. 123, the Company's net loss for the year ended December 31, 1996 and the six months ended June 30, 1997 would have been approximately $3,248,000 or $.77 per share and $2,688,000 or $.40 per share, respectively. The fair value of the options granted are estimated as $.06 and $.07 per share for the Discovery Plan and the ATI Plan, respectively for the year ended December 31, 1996 and $.10 per share for the six months ended June 30, 1997, on the date of grant using the Black-Scholes option-pricing model with the following weighted average assumptions: dividend yield 0%, volatility of 0%, risk-free interest rate of 6.7% for 1996 and 7% for 1997, and expected life of ten years.

NOTES TO UNAUDITED PRO FORMA COMBINED CONDENSED FINANCIAL STATEMENTS Note 1 The unaudited pro forma condensed combined balance sheet of the Company and Old Discovery has been prepared as if the Merger was completed as of October 31, 1997. The Merger will be accounted for as a purchase of the Company by Old Discovery, as Old Discovery's former stockholders own approximately 92% of the merged entity notwithstanding that the Company survived the Merger. The total cost of the proposed merger is estimated to be approximately $2.9 million, including transaction costs incurred by Old Discovery of approximately $400,000 which includes financial advisory, legal, and accounting fees. The purchase cost of the Company has been determined based on the estimated fair market value of Company stock at the time of the announcement of the Merger. The estimated purchase price consists of the following (in thousands): Estimated value of Common Stock to be held by pre-existing current Company stockholders following the Merger (1,639,300 shares of Common stock at $1.50 per share) $2459 Estimated transaction costs to be incurred by Old Discovery 400 ----- (Net of prior Old Discovery investment in the Company) $2859 ===== Based on a preliminary analysis of tangible and intangible assets the allocation of the purchase price is as follows: Tangible assets of the Company $1100 In-process research & development 3622 Liabilities of the Company assumed (including transaction costs) (1863) ------ $ 2859 ====== The in-process research and development will be charged against earnings. Such charge has not been reflected in the pro forma condensed statement of operations as such charge is a non-recurring charge directly attributable to the Merger. The pro forma adjustments include accrued liabilities of $1,125,000 to reflect the estimated costs incurred by both the Company and Old Discovery to complete the Merger. The pro forma adjustments include the repayment of approximately $1,200,000 in debt owned to Titan. No pro forma adjustment has been included to reflect the Titan Sublicense Agreement as there is no effect on the pro forma periods presented. Note 2 The unaudited pro forma condensed consolidated statements of operations of the Company and Old Discovery have been prepared as if the Merger was completed as of January 1, 1996 and January 1, 1997, respectively. The condensed consolidated statement of operations for the ten months ended October 31, 1997, includes an adjustment to reduce interest expense to reflect the repayment of Titan indebtedness in connection with the Merger. Note 3 Combined pro forma net loss per share for the year ended December 31, 1996 and the ten-month period ended October 31, 1997 is computed using the historical weighted average number of Old Discovery Common Stock outstanding, adjusted for the exchange ratio applicable to Common Stock in the Merger plus the shares of the Company Common Stock outstanding following the cancellation of Titan's holding in the Company. In addition, combined pro forma net loss per share for the ten-month period ended October 31, 1997 has been adjusted for the reverse stock split. Preferred stock and other common stock equivalents issued in the Merger are not included, as their effect is antidilutive.

EXHBIT 99.3 DISCOVERY LABORATORIES, INC FOR IMMEDIATE RELEASE - --------------------- Contact: James S. Kuo, M.D. President and Chief Executive Officer Discovery Laboratories, Inc. (212) 223-9504 Dian Griesel, Ph.D. The Investor Relations Group, Inc. (212) 664-8489 DISCOVERY LABORATORIES, INC. ANNOUNCES COMPLETION OF MERGER WITH ANSAN PHARMACEUTICALS, INC. New York, New York, November 25, 1997 - Discovery Laboratories, Inc. announced today that it has completed its merger with Ansan Pharmaceuticals, Inc. (Nasdaq: ANSN). Shareholders of Discovery will be issued securities representing approximately 92% of the stock of the combined entity on a fully diluted basis (exclusive of certain outstanding warrants). The newly formed company will assume the name Discovery Laboratories, Inc. As of October 31, 1997, Discovery, Acute Therapeutics, Inc. (a majority-owned subsidiary of Discovery) and Ansan had cash on hand of approximately $13 million. The new Nasdaq stock symbol, which is expected to be effective as of Monday, December 1, 1997 will be DSCO. Following the closing of the merger, the combined company effected a 1-for-3 reverse split of its common stock and warrants. Dr. James S. Kuo, President and CEO of the combined company stated, "We are tremendously excited about the strengthening of our product portfolio through this merger with Ansan. We are continuing to review the development programs on the technologies we have acquired from Ansan, namely, Apafant Injection for acute pancreatitis and AN10 Topical for chemotherapy induced hair loss." Dr. Kuo further stated, "We remain positive about our existing programs and will continue developing them either alone or with partners. Presently, an IND has been filed to permit the initiation of a Phase I clinical trial for ST-630, a novel vitamin D analog for post-menopausal osteoporosis. ST-630 is also the subject of a Phase II equivalent trial in Japan by two Japanese pharmaceutical companies. Surfaxin(TM) is presently in a Phase Ib trial for adult respiratory distress syndrome and a Phase II trial for meconium aspiration syndrome, and had a Phase II trial completed in infant respiratory distress syndrome by Johnson & Johnson prior to the licensure of the technology. SuperVent(TM), an aerosolized therapy for cystic fibrosis, is currently in a Phase I/II trial." Vaughan Shalson, formerly President and CEO of Ansan, has been named to the Board of Directors of the combined company. Commenting on the merger, Mr. Shalson noted that both Ansan and Discovery have focused on adding value in the clinical development of drugs, rather than in early research. "In combining the pipeline of drug products of the two companies," said Mr. Shalson, "we hope to mitigate some of the risks inherent in drug development. Moreover, with the combination of corporate infrastructure, management and financial resources, we expect to achieve measurable economies of scale and operational efficiencies." Discovery Laboratories, Inc. is a New York based development stage pharmaceutical company that is clinically developing proprietary pharmaceuticals to treat post-menopausal osteoporosis, adult respiratory distress syndrome, meconium aspiration syndrome and cystic fibrosis. Discovery's strategy is to accelerate and lower the risk of drug development by acquiring and developing proprietary pharmaceuticals for which significant animal or human testing has already been completed. In addition, Discovery seeks to minimize the cost of drug development by outsourcing preclinical development and manufacturing. Hospital based pharmaceuticals are developed at Discovery's majority-owned privately held subsidiary, Acute Therapeutics, Inc., located in Doylestown, PA.
