SUBJECT: Severance Payments

================================================================================

Thank you for agreeing to consider providing a Severance Payment Benefit to me
consistent with the benefit currently in place for the other members of the
Office of the Chairman.

The language should read as follows:

         Larry T. DeAngelo, Senior Vice President Administration and Secretary,
         Wilson Greatbatch Technologies, Inc. (WGT) will be granted a minimum of
         one year of severance payments should his employment be involuntarily
         terminated by WGT. WGT will not be obligated to provide severance pay
         should Mr. DeAngelo voluntarily terminate his employment, voluntarily
         retire, be discharged for cause or terminate due to disability or
         death. Voluntary separation may be triggered for "good reason" as
         defined in the Change of Control Agreement, however, excluding those
         provisions of that definition requiring a Change of Control event.

                                                    /s/ Edward F. Voboril
