Acquisition or Disposition of Assets On May 15, 2001 (the "Effective Time"), BioTransplant Incorporated ("BioTransplant") completed its acquisition of Eligix, Inc., a Delaware corporation ("Eligix"), pursuant to an Agreement and Plan of Merger dated December 8, 2000 (the "Merger Agreement") by and among BioTransplant, BT/EL Acquisition Co., a Delaware corporation and a wholly-owned subsidiary of BioTransplant (the "Transitory Sub"), and Eligix. Pursuant to the Merger Agreement, the Transitory Sub merged with and into Eligix at the Effective Time, whereupon Eligix became a wholly-owned subsidiary of BioTransplant (the "Merger"). In connection with the Merger, BioTransplant issued an aggregate of 4,939,248 shares of its Common Stock, $.01 par value per share (the "Merger Shares"), in exchange for all of the outstanding shares of Eligix capital stock. In addition, the outstanding options and warrants of Eligix as of the Effective Time were converted into options and warrants to purchase an aggregate of 670,555 shares of BioTransplant's Common Stock. In connection with the Merger, employees of Eligix will receive an aggregate of 990,000 shares of BioTransplant's Common Stock pursuant to the Eligix Management Equity Incentive Plan (the "Incentive Shares"). A total of 987,849 Merger Shares and 198,000 Incentive Shares (together, the "Escrow Shares") have been placed, or will be placed, in escrow in accordance with the terms of a related escrow agreement. One half of the Escrow Shares secure any indemnification obligations of the Eligix stockholders and/or employees, and any of these shares remaining in escrow on August 15, 2002 will be released to the former stockholders and employees of Eligix in accordance with the escrow agreement. The other one half of the Escrow Shares secure CE mark approval for Eligix' T-Cell HDM product and will only be distributed to the former Eligix stockholders and employees if Eligix achieves CE mark approval for its T-Cell HDM product by December 31, 2001. Based upon the capitalization of BioTransplant as of the Effective Time, the 5,929,248 shares of BioTransplant's Common Stock issued to the Eligix stockholders and employees represent approximately 33.4% of the outstanding shares of BioTransplant's Common Stock as of the Effective Time. Eligix stockholders and employees holding approximately 5,857,600 of the 5,929,248 shares of BioTransplant Common Stock issued in connection with the merger, have signed lock-up agreements that prohibit them from selling, transferring, pledging or otherwise disposing of the BioTransplant Common Stock that they receive in connection with the merger as set forth below: o through August 13, 2001, any of their shares; o during the period beginning on August 14, 2001 and ending on November 11, 2001, 66 2/3% of their shares; o during the period beginning on November 12, 2001 and ending on February 9, 2002, 33 1/3% of their shares; and o during the period beginning on February 10, 2002 and ending on May 15, 2002, 10% of their shares. Upon completion of the Merger, BioTransplant's board of directors elected Walter Ogier, Arnold Oronsky and Susan Racher, each a former member of Eligix' board of directors, to the BioTransplant board. In connection with the Merger, BioTransplant entered into employment offer letters with the following former key officers of Eligix, and the BioTransplant board of directors elected such individuals to the following offices: Walter C. Ogier (President and Chief Operating Officer), James Fitzgerald (Executive Vice President, Finance and Administration), David N. Cook (Senior Vice President, Development), Tara Clark (Vice President, Marketing), James Embree (Vice President, Manufacturing) and Judith Snow (Vice President, Quality Assurance). The Merger is intended to qualify as a tax-free reorganization within the meaning of Section 368(a) of the Internal Revenue Code of 1986, as amended. BioTransplant used authorized but previously unissued shares of its Common Stock as consideration in the Merger, which the Company expects to treat as a purchase for accounting purposes. Prior to the Merger, Eligix was a medical device company. BioTransplant currently intends to continue Eligix' business substantially in the manner conducted by Eligix prior to the Merger. The issuance of shares of BioTransplant Common Stock in connection with the Merger was approved by the board of directors and the stockholders of BioTransplant, and the Merger Agreement and the Merger were approved by the board of directors and stockholders of Eligix and the board of directors of BioTransplant. The terms of the Merger Agreement, including the amount of consideration paid by BioTransplant, were determined pursuant to arms' length negotiations. Prior to the closing of the Merger, none of BioTransplant, its affiliates, officers or directors, or any associate of any such officer or director, had any material relationship with Eligix or any of the stockholders of Eligix.
