Item 1.01. Entry into a Material Definitive Agreement
           ------------------------------------------
     
On October 25, 2005, Greatbatch, Inc. (the "Company") and Medtronic, Inc.
entered into a license agreement which grants Medtronic the right to use certain
intellectual property relating to tantalum capacitors. The license is perpetual
and, except for the Company's right to make and sell capacitors, exclusive to
Medtronic. The license provides for an initial license fee (due after
Medtronic's first U.S. sale) and royalties (some of which the Company must pay
to a third party). The royalties are subject to a maximum royalty amount and may
be eliminated within specified contract periods if Medtronic purchases a certain
percentage of its tantalum capacitor requirements from the Company. The Company
cannot provide any assurances that Medtronic will utilize its capacitor
technology or purchase any capacitors.
