Item 1.01.  Entry into a Material Definitive Agreement

            On October 27, 2004, Wilson Greatbatch Technologies, Inc. (the
            "Company") entered into a first amendment to its Supplier
            Partnering Agreement ("Amendment") with Pacesetter, Inc.,
            d/b/a St. Jude Medical CRMD. The Amendment is effective as
            of January 1, 2005. Pursuant to the Amendment, the parties
            have revised Section 9 to Exhibit A of the original
            agreement by extending the initial term of the agreement to
            8 years, and by revising pricing and terms for certain
            batteries. The original agreement went into effect on
            January 1, 2004 and was scheduled to expire at the end of
            2006. All other terms of the original agreement remain
            unchanged.

            On October 29, 2004, the Company issued a press release to announce
            that the parties entered into the Amendment. A copy of the press
            release is attached as Exhibit 99.1.

            The Company intends to file a copy of the Amendment with its
            Annual Report on Form 10-K for the fiscal year ended
            December 31, 2004.
