DISCOVERY LABORATORIES, INC. AND SUBSIDIARY (a development stage company) NOTE A - THE COMPANY AND BASIS OF PRESENTATION Discovery Laboratories, Inc., a former Delaware Corporation ("Old Discovery"") was incorporated in Delaware on May 18, 1993 as MicroBio, Inc. Until Old Discovery's merger with and into the Registrant on November 25, 1997 (the "Merger"), Old Discovery was 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 Old Discovery and its majority owned subsidiary, Acute Therapeutics, Inc. ("ATI"). Intercompany balances and transactions have been eliminated. No allocation of the subsidiary's net loss for the nine-month periods ended September 30, 1997 and 1996 has been attributed to the minority interest since the accumulated losses exceed the minorities' common equity interest during such periods . In the opinion of management, the financial statements include all adjustments, consisting of normal recurring accruals, necessary for a fair presentation of Old Discovey's financial position at September 30, 1997 and results of operations and cash flows for the nine-month periods ended September 30, 1997 and 1996. The financial statements for the nine-months ended September 30, 1997 are not necessarily indicative of the results that may be expected for the year ending December 31, 1997. In November 1996 Old Discovery completed a private placement of its securities and received aggregate net proceeds of approximately $19,000,000. NOTE B - 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 the Registrant's common stock issued to the common stockholders of Old Discovery upon consummation of the Merger. Common stock equivalents are not included in the calculation of net loss per share as the effect would be antidilutive. NOTE C - 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. Note D - Merger Pursuant to a merger agreement executed with the Registrant on July 16, 1997 (the "Merger Agreement"), Old Discovery's stockholders received approximately 90% of the combined entity. The Merger will be accounted for as a reverse acquisition with Old Discovery as the acquirer for financial reporting purposes. The Merger closed on November 25, 1997. Also on July 16, 1997 Old Discovery purchased 13,000 shares of Series A convertible preferred stock of the Registrant for $1,300,000 which amount was used by the Registrant to repay certain debt owed to its principal stockholder. The Series A convertible preferred stock was cancelled in the Merger. The Registrant's assets at September 30, 1997 consisted primarily of cash and short-term investments. F-5

DISCOVERY LABORATORIES, INC. AND SUBSIDIARY (a development stage company) Note E - Income Taxes At September 30, 1997, Old Discovery had available for federal income tax purposes net operating loss carryforwards of approximately $2,600,000 expiring through 2011, that may be used to offset future taxable income. 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. Old Discovery provided a valuation reserve against the full amount of the deferred tax asset of $3,030,000 arising from net operating loss benefit of approximately $1,000,000 the research and development write-off of approximately $1,130,000 and general and administrative costs of approximately 900,000 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 $1,800,000 for the nine months ended September 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. F-6


                                                                   EXHIBIT 99.5

         UNAUDITED PRO FORMA CONDENSED CONSOLIDATED FINANCIAL STATEMENTS

                  The following unaudited pro forma condensed combined financial
statements give effect to the Merger of the Registrant and Old Discovery
pursuant to the Merger Agreement. The unaudited pro forma condensed consolidated
balance sheet gives effect to the Merger as if it occurred on September 30,
1997. The unaudited pro forma condensed consolidated statement of operations
gives effect to the Merger as if it occurred on January 1, 1997.

                  The pro forma condensed consolidated financial statements are
based on the historical financial statements of the Registrant and Old
Discovery. They give effect to the Merger under the purchase method of
accounting and apply the assumptions and adjustments as discussed in the
accompanying notes to the pro forma condensed consolidated financial statements.
The pro forma condensed consolidated financial statements as of and for the nine
months ended September 30, 1997 have been prepared based upon the unaudited
condensed financial statements of the Registrant and the unaudited condensed
consolidated financial statements of Old Discovery as of September 30, 1997 and
for the nine months then ended.

                  The Merger will be accounted for using the purchase method of
accounting. Although the Registrant was the surviving corporate entity, Old
Discovery's former stockholders own approximately 92% of the merged entity.
Accordingly, the transaction will be accounted for as an acquisition of the
Registrant by Old Discovery. The unaudited pro forma condensed consolidated
financial statements have been prepared on the basis of assumptions described in
the notes thereto and include assumptions relating to the allocation of the
consideration paid for the assets and liabilities of the Registrant based on
preliminary estimates of their fair value. The actual allocation of such
consideration may differ from that reflected in the unaudited pro forma
condensed consolidated financial statements after final valuation procedures are
completed following the closing of the Merger. The final allocations of the
aggregate purchase price for the Merger are not expected to differ materially
from the preliminary allocations. In the opinion of the Registrant, all
adjustments necessary to present fairly the unaudited pro forma condensed
consolidated financial statements have been made based on the terms and
structure of the Merger.

                  The pro forma information is presented for illustrative
purposed only and is not necessarily indicative of the operating results or
financial position that would have occurred if the Merger had been consummated
on January 1, 1997 or September 30, 1997, respectively, nor is it necessarily
indicative of future operating results or financial position.

                  The pro forma condensed consolidated financial statements
should be read in conjunction with the historical financial statements and the
related notes thereto of the Registrant and Old Discovery in Amendment No. 2 to
the Ansan Pharmaceuticals, Inc. Form S-4 dated October 24, 1997, and
Management's Discussion and Analysis of Financial Condition and Plan of
Operations included therein.

                                                                            F-7

NOTES TO UNAUDITED PRO FORMA COMBINED CONDENSED FINANCIAL STATEMENTS Note 1 The unaudited pro forma condensed combined balance sheet of the Registrant and Old Discovery has been prepared as if the Merger was completed as of September 30, 1997. The Merger will be accounted for as a purchase of the Registrant by Old Discovery, as Old Discovery's former stockholders own approximately 92% of the merged entity notwithstanding that the Registrant survived the Merger. The total cost of the 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 Registrant has been determined based on the estimated fair market value of Registrant 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 Registrant stockholders following the Merger (546,433 shares of Common stock at $4.50 per share) $2459 Estimated transaction costs to be incurred by Old Discovery 400 ----- (Net of prior Old Discovery investment in the Registrant) $2859 ===== Based on a preliminary analysis of tangible and intangible assets the allocation of the purchase price is as follows: Tangible assets of the Registrant acquired (less previous investment by Old Discovery) $1259 In-process research & development 3433 Liabilities of the Registrant assumed (including transaction costs) (1833) ----- $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 Registrant and Old Discovery to complete the Merger. The pro forma adjustments include the repayment of approximately $1,200,000 in debt owed to Titan Pharmaceuticals, Inc. (the "Titan Indebtedness"). No pro forma adjustment has been included to reflect the Sublicense Agreement entered into between Titan Pharmaceuticals, Inc. and the Registrant at the time of the Merger as there is no effect on the pro forma periods presented. Note 2 The unaudited pro forma condensed consolidated statements of operations of the Registrant and Old Discovery have been prepared as if the Merger was completed as of January 1, 1997. The condensed consolidated statement of operations for the nine months ended September 30, 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 nine-month period ended September 30, 1997 is computed using the historical weighted average number of shares of Old Discovery Common Stock outstanding, adjusted for the exchange ratio applicable to Common Stock in the Merger plus the shares of the Registrant Common Stock outstanding following the cancellation of Titan Pharmaceuticals, Inc.'s holding in the Registrant and adjusted for the 1-for-3 reverse stock split effected concurrently with the Merger. Preferred stock and other common stock equivalents issued in the Merger are not included, as their effect is antidilutive. F-10
