     the meaning of Rule 13d-3 promulgated under the Exchange Act) of 25% or
     more of either (A) the then-outstanding shares of common stock of the
     Company (the "Outstanding Company Common Stock") or (B) the combined voting
     power of the then-outstanding voting securities of the Company entitled to
     vote generally in the election of directors (the "Outstanding Company
     Voting Securities"); provided, however, that, for purposes of this Section

<PAGE>

     approved by a vote of at least a majority of the directors then comprising
     the Incumbent Board shall be considered as though such individual were a
     member of the Incumbent Board, but excluding, for this purpose, any such
     individual whose initial assumption of office occurs as a result of an
     actual or threatened election contest with respect to the election or
     removal of directors or other actual or threatened solicitation of proxies
     or consents by or on behalf of a Person other than the Board.

     (3)    Consummation of a reorganization, merger, consolidation or sale or
     other disposition of all or substantially all of the assets of the Company
     (a "Business Combination"), in each case, unless, following such Business
     Combination, (A) all or substantially all of the individuals and entities
     that were the beneficial owners of the Outstanding Company Common Stock and
     the Outstanding Company Voting Securities immediately prior to such
     Business Combination beneficially own, directly or indirectly, more than
     60% of the then-outstanding shares of common stock and the combined voting
     power of the then-outstanding voting securities entitled to vote generally
     in the election of directors, as the case may be, of the corporation
     resulting from such Business Combination (including, without limitation, a
     corporation that, as a result of such transaction, owns the Company or all
     or substantially all of the Company's assets either directly or through one
     or more subsidiaries) in substantially the same proportions as their
     ownership immediately prior to such Business Combination of the Outstanding
     Company Common Stock and the Outstanding Company Voting Securities, as the
     case may be, (B) no Person (excluding any corporation resulting from such
     Business Combination or any employee benefit plan (or related trust) of the
     Company or such corporation resulting from such Business Combination)
     beneficially owns, directly or indirectly, 25% or more of, respectively,
     the then-outstanding shares of common stock of the corporation resulting
     from such Business Combination or the combined voting power of the then-
     outstanding voting securities of such corporation, except to the extent
     that such ownership existed prior to the Business Combination, and (C) at
     least a majority of the members of the board of directors of the
     corporation resulting from such Business Combination were members of the
     Incumbent Board at the time of the execution of the initial agreement or of
     the action of the Board providing for such Business Combination; or

     (4)    Approval by the shareholders of the Company of a complete
     liquidation or dissolution of the Company.
