     CLARENCE, N.Y.--(BUSINESS WIRE)--Oct. 31, 2005--Greatbatch, Inc. (the
"Company") (NYSE:GB) announced today that on October 25, 2005, the Company
entered into a royalty-bearing licensing agreement with Medtronic, Inc. This
agreement grants Medtronic rights with respect to certain intellectual property
relating to tantalum capacitors in exchange for an initial license fee payable
on Medtronic's first U.S. sales and stipulated royalty payments. The royalty
payments are subject to an agreed upon maximum and may be eliminated if
Medtronic purchases a stipulated percentage of their tantalum capacitors from
the Company. The royalty periods are for two initial five-year contract periods

are still valid and enforceable. The use of tantalum technology and any purchase
of tantalum capacitors by Medtronic are subject to their further internal
evaluation.
