     This Amendment No. 3 (this "Amendment") amends and supplements the Tender
Offer Statement on Schedule TO filed by Orchid Merger Corp., a Delaware
corporation ("Purchaser"), Smith & Nephew, Inc., a Delaware corporation ("Smith
& Nephew"), and Smith & Nephew plc, a corporation organized under the laws of
England and Wales ("Parent"), on February 22, 2002, as amended by Amendment No.
1 and Amendment No. 2 thereto (as amended, the "Schedule TO"), relating to the
offer to purchase all issued and outstanding shares of common stock, par value
$.001 per share, of ORATEC Interventions, Inc., a Delaware corporation
("ORATEC"), including the associated preferred stock purchase rights issued
pursuant to the Preferred Shares Rights Agreement dated as of November 28, 2000,
as amended, between ORATEC and American Stock Transfer & Trust Company, as
rights agent (collectively, the "Shares"), upon the terms and subject to the
conditions set forth in the Offer to Purchase dated February 22, 2002 and in the
related Letter of Transmittal. 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.

     After due inquiry and to the best of my knowledge and belief, I certify
