BACKGROUND

     A.   The Parties entered into a Supplier Partnering Agreement (the
          "Agreement") effective January 1, 2004.

     B.   The Parties to the Agreement desire to revise the following:

          a.   Security / Safety stocks of key raw materials, including
               "specialty metals"

          b.   The ongoing financial liability of maintaining said raw material
               safety stock, including "specialty metals".

AGREEMENT

In consideration of the foregoing Recitals and the Parties mutual covenants
contained herein, the Parties hereby agree as follows:

     1.   Pacesetter desires for Greatbatch to maintain secured safety stock of
          Grade 9 Titanium (raw material) to ensure an ongoing, uninterrupted
          supply and flow of finished case product. As such, Pacesetter requires
          and Greatbatch agrees to purchase an initial * of raw material. Any
          additional purchases of raw material must be approved in writing by
          Pacesetter prior to purchase.

     2.   Pacesetter, Inc. further guarantees the requisite purchase of Grade 9
          cases, sufficient to consume the initial (Greatbatch purchased) * and
          any future acquisitions of Grade 9 material purchases (per item 1), or
          at it's option, Pacesetter agrees to purchase the raw material
          (including normal carrying costs) from Greatbatch within * after
          material receipt at Greatbatch, Inc. The expected material receipt is
          *.




     3.   Both parties agree, in good faith to increase (or decrease) the price
          of completed shields by the proportionate variance of raw Titanium
          material on * due to inherent market price / cost fluctuation. Only
          price / cost variance beyond * will require pricing changes. Reference
          current grade 9 titanium market price quoted by Hamilton Precision
          Metals is *.

     4.   Except as provided herein, all of the terms and conditions of the
          agreement shall remain unchanged and in full force and effect.

The parties have caused this amendment to be executed by their respective duly
authorized representatives as of the effective date.
