("HAC"), an indirect wholly owned subsidiary of the Reporting Person, with principal executive offices located at One Franklin Plaza (FP 2355), 200 N. 16th Street, Philadelphia, PA 19102. Of the shares of common stock to which this Form 3 relates, 53,251 were previously owned by the Reporting Person or its subsidiaries, and 158,607,627 were acquired by HAC for $14.25 per share, in a tender offer for all outstanding shares of common stock of Human Genome Sciences, Inc. ("HGS"), upon the terms and subject to the conditions set forth in the Offer to Purchase dated May 10, 2012, which was annexed to and filed with the Schedule TO filed by the Reporting Person with the Securities and Exchange Commission on May 10, 2012, as amended and supplemented from time to time (the "Offer"). An additional 9,155,762 shares were tendered in the Offer pursuant to guaranteed delivery procedures.
2. Pursuant to the Agreement and Plan of Merger dated as of July 16, 2012, by and among the Reporting Person, HAC and HGS, following the closing of the Offer, the Reporting Person was entitled to designate a number of directors of HGS, equal to the product of the total number of directors on HGS's board of directors and the percentage that the number of shares beneficially owned by the Reporting Person and its subsidiaries bore to the total number of shares outstanding. On July 30, 2012, following the closing of the Offer, all of the directors of HGS resigned from the HGS board of directors, other than Argeris N. Karabelas, Augustine Lawlor and Gregory Norden, and such remaining directors of HGS appointed Deirdre Connelly, Roger Connor, Chester Koczynski, Adrian Rawcliffe, David Redfern, Ian Tomlinson and Daniel Troy, each of whom was designated by the Reporting Person, to the HGS board of directors. Each of the foregoing individuals is an employee of the Reporting Person.
