("Gilead") acquired all of the outstanding stock of NeXstar Pharmaceuticals, Inc., a Delaware corporation (the "Company" or "NeXstar"), pursuant to an Agreement and Plan of Merger, dated as of February 28, 1999 (the "Merger Agreement"), among Gilead, the Company, and a merger subsidiary wholly owned by Gilead. Pursuant to the Merger Agreement, the Company was merged with the wholly owned subsidiary of Gilead, with the Company as the surviving corporation (the "Merger"). As a result of the Merger, the Company became a wholly owed subsidiary of Gilead. In connection with the Merger, Gilead issued a total of approximately 11,212,730 shares of Gilead common stock, or 0.3786 of a share of Gilead common stock for each share of Company common stock, to the existing stockholders of the Company as consideration for all shares of capital stock of the Company. In addition, holders of options and warrants outstanding at the time of the Merger to purchase an aggregate of approximately 2,236,413 shares of Company common stock will receive, upon exercise of such options and warrants, the same fraction of a share of Gilead's common stock per share of Company common stock, and holders of $80,000,000 principal amount of 6 1/4% Convertible Subordinated Debentures of the Company (the "Debentures") will now have the right to convert the Debentures into an indeterminate number of shares of Gilead Common Stock, pursuant to a First Supplemental Indenture dated July 29, 1999 by and among IBJ Whitehall Bank & Trust Company ("IBJ Whitehall") as Trustee, the Company and Gilead amending the Indenture between the Company and IBJ Whitehall dated July 31, 1997.

The Company is an integrated biopharmaceutical company engaged in the discovery, development, manufacture and marketing of proprietary pharmaceutical products to treat life-threatening and other serious infectious, oncological and hematalogical diseases. Gilead intends to continue to use the assets acquired to conduct such business. ITEM 5. OTHER EVENTS. At Gilead's Annual Meeting of Stockholders on July 29, 1999, the stockholders of Gilead approved an amendment to Gilead's restated certificate of incorporation to increase the authorized shares of Gilead common stock from 60,000,000 to 100,000,000 shares.

On a combined basis, there were no material transactions between Gilead and NeXstar (the "Combined Company") during any period presented. There are no material differences between the accounting policies of Gilead and NeXstar. The pro forma combined provisions for income taxes do not represent the amount that would have resulted had Gilead and NeXstar filed consolidated income tax returns during the periods presented. Any unrecognized future deductible temporary differences will be evaluated on a quarterly basis based upon the income tax attributes of the Combined Company. NOTE 2. PRO FORMA CONDENSED COMBINED BALANCE SHEET The Pro Forma Condensed Combined Balance Sheet reflects a credit balance in accounts receivable for Gilead. This balance of $(0.1) million primarily represents the remaining balance of $(0.3) million from aggregate provisions for product returns of $(0.8) million recorded since December 31, 1998 in accordance with the Company's sales return policy. This $(0.3) million remaining allowance for product returns, along with previously recorded reserves for cash discounts, government discounts and rebates, and bad debts, exceeded gross outstanding accounts receivable of $0.5 million as of June 30, 1999. NOTE 3. PRO FORMA COMBINED EARNINGS (LOSS) PER SHARE Under the merger agreement, each share of NeXstar common stock converted into the right to receive 0.3786 of a share of Gilead stock (the "Exchange Ratio"). The Exchange Ratio was used in computing share and per share amounts in the accompanying unaudited pro forma condensed combined financial statements. NOTE 4. MERGER COSTS The Pro Forma Condensed Combined Balance Sheet at June 30, 1999 reflects an adjustment of $9 million for direct merger-related transaction costs, primarily consisting of professional and registration fees.
