A "Change of Control" shall be deemed to have occurred at any of the following times: A. Upon the acquisition (other than from the Company) by any person, entity or "group," within the meaning of Section 13(d)(3) or 14(d)(2) of the Securities Exchange Act of 1934 (the "Exchange Act") (excluding, for this purpose, the Company or its affiliates, or any employee benefit plan of the Company or its affiliates which acquires beneficial ownership of voting securities of the Company) of beneficial ownership (within the meaning of Rule 13d-3 promulgated under the Exchange Act) of 50% or more of either the then outstanding shares of common stock of the Company or the Combined Voting Power of the Company's then outstanding voting securities.

At the time individuals who, as of [date], constitute the Board (as of [date], the "Incumbent Board") cease for any reason to constitute at least a majority of the Board, provided that any person becoming a director subsequent to [date] whose election, or nomination for election by the Company's shareholders, was approved by a vote of at least a majority of the directors then comprising the Incumbent Board (other than an election or nomination of an individual whose initial assumption of office is in connection with an actual or threatened election contest relating to the election of the directors of the Company, as such terms are used in Rule 14a-11 of Regulation 14A promulgated under the Exchange Act) shall be, for purposes of this subparagraph B, considered as though such person were a member of the Incumbent Board; or C. Upon the approval by the shareholders of the Company of a reorganization, merger, consolidation (in each case, with respect to which persons who were the shareholders of the Company immediately prior to such reorganization, merger or consolidation do not, immediately thereafter, own more than 50% of the Combined Voting Power of the reorganized, merged or consolidated company's then outstanding voting securities) or a liquidation or dissolution of the Company or of the sale of all or substantially all of the assets of the Company; or D. The occurrence of any other event which the Incumbent Board in its sole discretion determines constitutes a Change of Control. 3 The following paragraph will be substituted in lieu of Section e)2. on page 6 of each plan: Profit for bonus determination will be inclusive of any changes in reserves, but will exclude any capital gains or losses, other unusual gains or losses such as proceeds of fire or casualty insurance, and extraordinary items. In cases of uncertainty, the decision of the CEO will be final. In the event of a Change of Control, the Compensation Committee shall adjust profit for bonus determination purposes hereunder to remove distortions in the Company's profits and distortions in the method of measuring such profits, and distortions in the methods used to determine and measure the realization of the performance targets hereunder for bonus calculation purposes, that have occurred as a result of the Change of Control. In addition, the Compensation Committee shall have the authority, in its sole and absolute discretion, to adjust the performance targets hereunder for bonus calculation purposes to remove distortions in the realization of such targets and distortions in the method of measuring such realization and such targets, caused by actions taken or expenses incurred by the Company in connection with a proposal for a transaction described in subparagraphs A or C of the definition of Change of Control set forth in subsection e)1. above, or any other extraordinary transaction, whether or not consummated. No changes in reserves shall be taken into account for purposes of bonus calculations hereunder with respect to the fiscal year in which a Change of Control occurs and the immediately following fiscal year.
