       The terms of the ESOP provide for the voting rights associated with the
common stock held by the ESOP Trust to be passed through and exercised
exclusively by the participants in the ESOP to the extent that such securities
are allocated to ESOP participants' accounts. Any shares held in the unallocated
account maintained by the ESOP Trustee prior to their allocation to the accounts
of ESOP participants are voted by the ESOP Trustee at the direction of the Plan
Administrator.

       The current members of the committee acting as Plan Administrator are:
James R. McKenzie, Robert J. Welch, David J. Losito, Joshua L. Targoff and
Richard B. Shane, Jr. Pursuant to Rule 13d-4, each such member disclaims
beneficial ownership of shares of common stock that may be deemed to be

ownership as a participant in the ESOP.
