Capitalized terms used but not defined herein have the meanings assigned to such terms in the Schedule TO. This Amendment also amends and supplements the Schedule 13D of Purchaser, Smith & Nephew and Parent originally filed on February 22, 2002, as amended. Item 1 through Item 11. Items 1 through 11 of the Schedule TO are hereby amended and supplemented by adding the following thereto: On March 28, 2002, the merger of Purchaser with and into ORATEC (the "Merger") became effective, with ORATEC surviving the Merger as a direct wholly owned subsidiary of Smith & Nephew. As a result of the Merger, each Share issued and outstanding immediately prior to the effective time of the Merger (other than Shares owned by ORATEC, Smith & Nephew or any wholly owned subsidiary of Smith & Nephew) was automatically cancelled and became the right to receive cash, without interest, in the amount of $12.50 per Share. The Merger completes the purchase of ORATEC by Smith & Nephew. SIGNATURE After due inquiry and to the best of my knowledge and belief, I certify that the information set forth in this statement is true, complete and correct.
