     This First Amendment to Preferred Shares Rights Agreement, dated as of
February 13, 2002 (this "Amendment"), to the Preferred Shares Right Agreement,
                         ---------
dated as of November 28, 2000 (the "Rights Agreement"), is entered into by and
                                    ----------------
between ORATEC Interventions, Inc., a Delaware corporation (the "Company") and
                                                                 -------
American Stock Transfer and Trust Company (the "Rights Agent").
                                                ------------

     A.   The Company and the Rights Agent have entered into the Rights
Agreement. Pursuant to Section 27 of the Rights Agreement, prior to the
Distribution Date (as defined in the Agreement), the Company may supplement or
amend the Rights Agreement in any respect without the approval of any holders of
Rights and the Company may cause the Rights Agent to execute such amendment.

     B.   As of the date of this Amendment, the Distribution Date has not
occurred.

     C.   The Board of Directors of the Company has determined that it is in the
best interests of the Company and its stockholders to enter into an Agreement
and Plan of Merger, dated as of February 13, 2002, by and among
Smith & Nephew, Inc., a Delaware corporation ("Parent"),
                                               ------
ORATEC Interventions, Inc., a Delaware corporation and a wholly-owned subsidiary
of Parent ("Sub") and the Company (the "Merger Agreement").
            ---                         ----------------

     D.   As a condition to the willingness of Parent and Sub to enter into the
Merger Agreement, certain stockholders of the Company are entering into
Stockholder Agreements, each dated as of February 13, 2002, with Parent and Sub
(the "Stockholder Agreements").
      ----------------------

     E.   As a further condition to the willingness of Parent and Sub to enter
into the Merger Agreement, the Company is required to amend the Rights Agreement
such that the Rights and the Rights Agreement are inapplicable to the Offer (as
defined in the Merger Agreement), the Merger (as defined in the Merger
Agreement) and the Stockholder Agreements.

     In consideration of the foregoing, the parties agree as follows:

     1.   Amendments to the Rights Agreement. The Rights Agreement is hereby
          ----------------------------------
amended as follows:

          a.   The definition of "Acquiring Person" set forth in Section 1(a) of
the Rights Agreement is hereby amended and restated in its entirety to read as
follows:

               "(a) "Acquiring Person" shall mean any Person who or which,
                     ----------------
               together with all Affiliates and Associates of such Person, shall
               be the Beneficial Owner of 15% or more of the Common Shares then
               outstanding, but shall not include (i) the Company, any
               Subsidiary of the Company or any employee benefit plan of the

                                      -1-



               Company or of any Subsidiary of the Company, or any entity
               holding Common Shares for or pursuant to the terms of any such
               plan, nor (ii) Smith & Nephew, Inc. ("Parent") or Orchid Merger
                                                     ------
               Corp. ("Sub") or any of their Affiliates or Associates (the "S&N
                       ---                                                  ---
               Group") in the event that the S&N Group shall become the
               -----
               Beneficial Owners of Common Shares of the Company upon the
               execution of, or in one or more transactions contemplated by, and
               not in contravention of, the Agreement and Plan of Merger, dated
               as of February 13, 2002, by and among Parent, Sub and the Company
               or the Stockholder Agreements, dated as of February 13, 2002, by
               and between Parent and certain holders of Common Shares of the
               Company. Notwithstanding the foregoing, no Person shall be deemed
               to be an Acquiring Person either (i) as the result of an
               acquisition of Common Shares by the Company which, by reducing
               the number of shares outstanding, increases the proportionate
               number of shares beneficially owned by such Person to 15% or more
               of the Common Shares of the Company then outstanding; provided,
                                                                     --------
               however, that if a Person shall become the Beneficial Owner of
               -------
               15% or more of the Common Shares of the Company then outstanding
               by reason of share purchases by the Company and shall, after such
               share purchases by the Company, become the Beneficial Owner of
               any additional Common Shares of the Company, (other than pursuant
               to a dividend or distribution paid or made by the Company on the
               outstanding Common Shares in Common Shares or pursuant to a split
               or subdivision of the outstanding Common Shares), then such
               Person shall be deemed to be an Acquiring Person unless upon
               becoming the Beneficial Owner of such additional Common Shares of
               the Company such Person does not beneficially own 15% or more of
               the Common Shares of the Company then outstanding.
               Notwithstanding the foregoing, (i) if the Board of Directors of
               the Company determines in good faith that a Person who would
               otherwise be an "Acquiring Person" as defined pursuant to the
               foregoing provisions of this Section 1(a) has become such
               inadvertently (including, without limitation, because (A) such
               Person was unaware that it beneficially owned a percentage of the
               Common Shares that would otherwise cause such Person to be an
               "Acquiring Person," as defined pursuant to the foregoing
               provisions of this Section 1(a) or (B) such Person was aware of
               the extent of the Common Shares it beneficially owned but had no
               actual knowledge of the consequences of such beneficial ownership
               under this Agreement) and without any intention of changing or
               influencing control of the Company, and if such Person divested
               or divests as promptly as practicable a sufficient number of
               Common Shares so that such Person would no longer be an
               "Acquiring Person," as defined pursuant to the foregoing
               provisions of this Section 1(a), then such Person shall not be
               deemed to be or to have become an "Acquiring Person" for any
               purposes of this Agreement; and (ii) if, as of the date hereof,
               any Person is the Beneficial Owner of 15% or more of the Common
               Shares outstanding, such Person shall not be or become an
               "Acquiring Person," as defined pursuant to the foregoing
               provisions of this Section 1(a), unless and until such time as
               such Person shall become the Beneficial Owner of additional
               Common Shares (other than pursuant to a dividend or distribution
               paid or made by the Company on the outstanding Common Shares in
               Common Shares or

                                       -2-



               pursuant to a split or subdivision of the outstanding Common
               Shares), unless, upon becoming the Beneficial Owner of such
               additional Common Shares, such Person is not then the Beneficial
               Owner of 15% or more of the Common Shares then outstanding."

               b.   The definition of "Distribution Date" set forth in
Section 1(h) of the Rights Agreement is hereby amended and restated in its
entirety to read as follows:

               "(h) "Distribution Date" shall mean the earlier of (i) the Close
                     -----------------
               of Business on the tenth day (or such later date as may be
               determined by action of a majority of the Board of Directors)
               after the Shares Acquisition Date (or, if the tenth day after the
               Shares Acquisition Date occurs before the Record Date, the Close
               of Business on the Record Date) or (ii) the Close of Business on
               the tenth day (or such later date as may be determined by action
               of a majority of the Board of Directors) after the date that a
               tender or exchange offer by any Person (other than (A) the
               Company, any Subsidiary of the Company, any employee benefit plan
               of the Company or of any Subsidiary of the Company, or any Person
               or entity organized, appointed or established by the Company for
               or pursuant to the terms of any such plan or (B) the S&N Group,
               provided that in each case involving a member of the S&N Group
               such action shall be in accordance with, and not in contravention
               of, the terms of the Merger Agreement and the Stockholder
               Agreements) is first published or sent or given within the
               meaning of Rule 14d-2(a) of the General Rules and Regulations
               under the Exchange Act, if, assuming the successful consummation
               thereof, such Person would be the Beneficial Owner of 15% or more
               of the shares of Common Stock then outstanding."

     2.   Governing Law. This Amendment shall be deemed to be a contract made
          -------------
under the laws of the State of Delaware and for all purposes shall be governed
by and construed in accordance with laws of such State applicable to contracts
to be made and performed entirely within such State.

     3.   Counterparts. This Amendment may be executed in any number of
          ------------
counterparts, each of which shall be an original and all such counterparts shall
together constitute one and the same instrument.

          Terms used herein but not defined herein shall have the meaning set
forth in the Rights Agreement.

                                       -3-
