Item 1.01 Entry into a Material Definitive Agreement

     On June 29, 2007, Greatbatch Ltd. ("GL"), a subsidiary of Greatbatch, Inc.
     (the "Company") entered into a supply agreement with Cardiac Pacemakers,
     Inc., a subsidiary of Boston Scientific Corporation ("BSC"). Under the
     terms of the supply agreement, BSC has agreed to purchase from GL a certain
     percentage of the batteries, capacitors, and case halves it uses in its
     implantable medical devices at prices stated in the supply agreement. The
     supply agreement is effective as of July 1, 2007, and the initial term of
     the supply agreement ends on December 31, 2010. The agreement may be
     renewed for one or more four year renewal terms upon mutual agreement of
     the parties. The prices stated in the supply agreement are subject to
     adjustment for changes in cost, and the prices of certain batteries and
     capacitors stated in the supply agreement are subject to adjustment for
     changes in volume.

     The supply agreement replaces the battery supply agreement between GL and
     Cardiac Pacemakers Inc. d/b/a Guidant entered into on April 10, 2003, as
     amended, and replaces the capacitor supply agreement between the Company
     and Guidant/CRM entered into on September 15, 2001, as amended. A pricing
     letter from BSC dated January 29, 2007, as amended, is also replaced by the
     supply agreement.

     The Company will seek confidential treatment pursuant to Rule 24b-2 of the
     Securities Exchange Act of 1934, as amended, with respect to portions of
     the supply agreement and file the supply agreement with its quarterly
     report on Form 10-Q for the fiscal quarter ended June 29, 2007.
