                  (a) The acquisition by any individual, entity or group (within
         the meaning of Section 13(d)(3) or 14(d)(2) of the Securities Exchange
         Act of 1934, as amended (the "Exchange Act")) (a "Person") of
         beneficial ownership (within the meaning of Rule 13d-3 promulgated
         under the Exchange Act) of 20% or more of either (i) the then
         outstanding shares of Common Stock (the "Outstanding Company Common
         Stock") or (ii) 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 subsection (a), the

         any acquisition directly from the Company, (ii) any acquisition by the
         Company, (iii) any acquisition by any employee benefit plan (or related
         trust) sponsored or maintained by the Company or any corporation
         controlled by the Company or (iv) any acquisition by any corporation

                  (b) Individuals who, as of the date hereof, constitute the
         Board (the "Incumbent Board") cease for any reason to constitute at
         least a majority of the Board; provided, however, that any individual
         becoming a director subsequent to the date hereof whose election, or
         nomination for election by the Company's stockholders, was 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; or

                  (c) Consummation of a reorganization, merger or consolidation
         or sale or other disposition of all or substantially all of the assets
         of the Company or the acquisition of assets of another corporation (a
         "Business Combination"), in each case, unless, following such Business
         Combination, (i) all or substantially all of the individuals and
         entities who were the beneficial owners, respectively, of the
         Outstanding Company Common Stock and Outstanding Company Voting
         Securities immediately prior to such Business Combination beneficially
         own, directly or indirectly, more than 50% of, respectively, 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 which 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 Outstanding Company Voting
         Securities, as the case may be, (ii) 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, 20% 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 entitled to vote generally in the election of directors of
         such corporation except to the extent that such ownership existed prior
         to the Business Combination and (iii) 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

                  (d) Approval by the stockholders of the Company of a complete
         liquidation or dissolution of the Company."

         2. Section 4.1 (d) of the Plan is amended by adding the following at
the end of the second sentence thereof:


                                       3
   3

         "provided, however, that (i) in the event of a Change of Control of the
         type set forth in paragraph (a), (b) or (d) of the definition of Change
         of Control and (ii) immediately prior to the occurrence of a Change of
         Control of the type set forth in paragraph (c) of the definition of
         Change of Control, each Option outstanding under the Plan shall become
         exercisable in whole or in part without regard to any vesting
         provisions set forth in the related Option Agreement."

         3. Subsection 4.2 of the Plan is amended by deleting therefrom in its
entirety the second paragraph thereof and inserting in lieu thereof the
following:

                  "Subject to any action required by the shareholders of the
         Company, in the event of a Business Combination that does not result in
         a Change of Control, each Option outstanding under the Plan shall
         pertain to and apply to the securities or other consideration that a
         holder of the number of shares of Common Stock underlying the Option
         would have been entitled to receive in the Business Combination. In the
         event of a Business Combination that results in a Change of Control of
         the type set forth in paragraph (c) of the definition of Change of
         Control or in the event of the complete liquidation or dissolution of
         the Company, then each outstanding Option shall terminate; provided,
         however, that each Optionee shall, in such event, have the right
         immediately prior to such Change of Control or complete liquidation or
         dissolution, to exercise his or her Option in whole or in part without
         regard to any installment provision that might be contained in the
         applicable Option Agreement."

         4. The Company reserves the right by action of the Board to amend
further at any time any of the terms and provisions of the Plan as amended
hereby. Except as expressly or by necessary implication amended hereby, the Plan
shall continue in full force and effect.
