Acquisition or Disposition of Assets On May 13, 1999, Voodoo Merger Sub, Inc. ("Merger Sub"), a wholly-owned subsidiary of 3Dfx Interactive, Inc. ("3Dfx"), merged (the "Merger") with and into STB Systems, Inc. ("STB"), with STB being the surviving corporation in the Merger. At special meetings of shareholders, the shareholders of each of 3Dfx and STB approved the Merger. As a result of the Merger, STB has become a wholly owned subsidiary of 3Dfx. STB designs, develops, manufactures, and markets graphics boards for use in desktop personal computers. The Merger occurred pursuant to the terms of an Agreement and Plan of Reorganization dated as of December 13, 1998 (the "Merger Agreement") by and among 3Dfx, STB and Merger Sub. Pursuant to the Merger Agreement, each share of Common Stock of STB ("STB Common Stock") outstanding immediately prior to the Effective Time (as defined in the Merger Agreement) was converted into the right to receive 0.65 (the "Exchange Ratio") of a share of 3Dfx's Common Stock. Based on the outstanding Common Stock of STB, 3Dfx expects to issue approximately 8,267,000 shares of 3Dfx Common Stock. No fractional shares will be issued and in lieu therefor STB shareholders will receive a cash payment equal to the fraction of a share multiplied by $18.50. In addition, 3Dfx will assume options to purchase 842,451 shares of STB Common Stock outstanding immediately prior to the Effective Time. These options will be converted into an option to acquire 65% as many shares of 3Dfx Common Stock, at an exercise price per share equal to the exercise price per share of the STB Common Stock under such STB option immediately prior to the merger divided by the Exchange Ratio. Additionally, an outstanding warrant to purchase shares of STB Common Stock was assumed by 3Dfx and converted into a warrant to acquire 65% of as many shares of 3Dfx Common Stock, at an exercise price per share equal to the exercise price per share of the STB Common Stock under such warrant immediately prior to the merger divided by the Exchange Ratio. In connection with the Merger, 3Dfx issued or reserved an aggregate of approximately 9,680,000 shares of Common Stock, including shares issued upon conversion of the above-described warrants and the shares issuable upon exercise of outstanding options. The Common Stock of 3Dfx issued in the Merger was registered under the Securities Act of 1933, as amended (the "Securities Act"), pursuant to a Registration Statement on Form S-4 (File No. 333-76355) (the "Registration Statement") which the Securities and Exchange Commission (the "Commission") declared effective on April 15, 1999. The Common Stock of 3Dfx issuable upon exercise of options to purchase STB Common Stock was registered under the Securities Act pursuant to a Registration Statement on Form S-8 which was filed with the Commission on May 20, 1999. The Merger constitutes a tax-free reorganization for federal income tax purposes and will be accounted for as a "purchase" by 3Dfx. The Merger is more fully described in 3Dfx's Registration Statement.
