LIMITATION OF RIGHTS. (a) NO RIGHT TO CONTINUE AS A DIRECTOR. Neither the Plan, nor the granting of an option nor any other action taken pursuant to the Plan, shall constitute or be evidence of any agreement or understanding, express or implied, that the Company will retain a director for any period of time. (b) NO STOCKHOLDERS' RIGHTS FOR OPTIONS. An optionee shall have no rights as a stockholder with respect to the shares covered by his options until the date of the issuance to him of a stock certificate therefor, and no adjustment will be made for dividends or other rights for which the record date is prior to the date such certificate is issued. 9. CHANGES IN COMMON STOCK (a) If (x) the outstanding shares of Common Stock are increased, decreased or exchanged for a different number or kind of shares or other securities of the Company, or (y) additional shares or new or different shares or other securities of the Company or other non-cash assets are distributed with respect to such shares of Common Stock or other securities, through or as a result of any merger, consolidation, sale of all or substantially all of the assets of the Company, reorganization, recapitalization, reclassification, stock dividend, stock split, reverse stock split or other similar transaction with respect to such shares of Common Stock, or other securities, an appropriate and proportionate adjustment shall be made in (i) the maximum number and kind of shares reserved for issuance under the Plan, and (ii) the number and kind of shares or other securities subject to then outstanding options under the Plan and (iii) the price for each share subject to any then outstanding options under the Plan, without changing the aggregate purchase price -4- 5 as to which such options remain exercisable. No fractional shares will be issued under the Plan on account of any such adjustments. Notwithstanding the foregoing, no adjustment shall be made pursuant to this Section 9 if such adjustment would cause the Plan to fail to comply with Rule 16b-3 or any successor rule promulgated pursuant to Section 16 of the Securities Exchange Act of 1934. (b) In the event that the Company is merged or consolidated into or with another corporation (in which consolidation or merger the stockholders of the Company receive distributions of cash or securities of another issuer as a result thereof), or in the event that all or substantially all of the assets of the Company is acquired by any other person or entity, or in the event of a reorganization or liquidation of the Company, the Board of Directors of the Company, or the board of directors of any corporation assuming the obligations of the Company, shall, subject to the provisions of Section 10, as to outstanding options, take one or more of the following actions: (i) provide that such options shall be assumed, or equivalent options shall be substituted, by the acquiring or succeeding corporation (or an affiliate thereof), (ii) upon written notice to the optionees, provide that all unexercised options will terminate immediately prior to the consummation of such transaction unless exercised by the optionee within a specified period following the date of such notice, or (iii) if, under the terms of a merger transaction, holders of the Common Stock of the Company will receive upon consummation thereof a cash payment for each share surrendered in the merger (the "Merger Price"), make or provide for a cash payment to the optionees equal to the difference between (A) the Merger Price times the number of shares of Common Stock subject to such outstanding options (to the extent then exercisable at prices not in excess of the Merger Price) and (B) the aggregate exercise price of all such outstanding options in exchange for the termination of such options. 10. CHANGE IN CONTROL Notwithstanding any other provision to the contrary in this Plan, in the event of a Change of Control (as defined below), all options outstanding as of the date such Change in Control occurs shall become exercisable in full, whether or not exercisable in accordance with their terms. A "Change in Control" shall occur or be deemed to have occurred only if any of the following events occur: (i) any "person," as such term is used in Sections 13(d) and 14(d) of the Securities Exchange Act of 1934, as amended, (other than the Company, any trustee or other fiduciary holding securities under an employee benefit plan of the Company, or any corporation owned directly or indirectly by the stockholders of the Company in substantially the same proportion as their ownership of stock of the Company) is or becomes the "beneficial owner" (as defined in Rule 13d-3 under the Securities Exchange Act of 1934), directly or indirectly, of securities of the Company representing 50% or more of the combined voting power of the Company's then outstanding securities; (ii) individuals who, as of July 1, 1992, constitute the Board of Directors of the Company (as of the date -5- 6 thereof, 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 the date thereof 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 (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 under the Securities Exchange Act of 1934) shall be, for purposes of this Agreement, considered as though such person were a member of the Incumbent Board; (iii) the stockholders of the Company approve a merger or consolidation of the Company with any other corporation, other than (A) a merger or consolidation which would result in the voting securities of the Company outstanding immediately prior thereto continuing to represent (either by remaining outstanding or by being converted into voting securities of the surviving entity) more than 50% of the combined voting power of the voting securities of the Company or such surviving entity outstanding immediately after such merger or consolidation or (B) a merger or consolidation effected to implement a recapitalization of the Company (or similar transaction) in which no "person" (as hereinabove defined) acquires more than 30% of the combined voting power of the Company's then outstanding securities; or (iv) the stockholders of the Company approve a plan of complete liquidation of the Company or an agreement for the sale or disposition by the Company of all or substantially all of the Company's assets." 11. AMENDMENT OF THE PLAN The Board of Directors may suspend or discontinue the Plan or review or amend it in any respect whatsoever; provided, however, that without approval of the stockholders of the Company no revision or amendment shall change the number of shares subject to the Plan (except as provided in Section 9), change the designation of the class of directors eligible to receive options, or materially increase the benefits accruing to participants under the Plan. The Plan may not be amended more than once in any six-month period. 12. WITHHOLDING The Company shall have the right to deduct from payments of any kind otherwise due to the optionee any federal, state or local taxes of any kind required by law to be withheld with respect to any shares issued upon exercise of options under the Plan. 13. EFFECTIVE DATE AND DURATION OF THE PLAN (a) EFFECTIVE DATE. The Plan shall become effective when adopted by the Board of Directors, but no option granted under the Plan shall become exercisable -6- 7 unless and until the Plan shall have been approved by the Company's shareholders. If such shareholder approval is not obtained within twelve months after the date of the Board's adoption of the Plan, all options granted under the Plan shall terminate and no further options shall be granted under the Plan. Amendments to the Plan not requiring shareholder approval shall become effective when adopted by the Board of Directors; amendments requiring shareholder approval (as provided in Section 11) shall become effective when adopted by the Board of Directors, but no option granted after the date of such amendment shall become exercisable (to the extent that such amendment to the Plan was required to enable the Company to grant such option to a particular optionee) unless and until such amendment shall have been approved by the Company's shareholders. If such shareholder approval is not obtained within twelve months of the Board's adoption of such amendment, any options granted on or after the date of such amendment shall terminate to the extent that such amendment to the Plan was required to enable the Company to grant such option to a particular optionee. Subject to this limitation, options may be granted under the Plan at any time after the effective date and before the date fixed for termination of the Plan. (b) TERMINATION. Unless sooner terminated in accordance with Section 9, the Plan shall terminate upon the earlier of (i) the close of business on the day next preceding the fifth anniversary of the date of its approval by the Company's stockholders, or (ii) the date on which all shares available for issuance under the Plan shall have been issued pursuant to the exercise or cancellation of options granted under the Plan. If the date of termination is determined under (i) above, then options outstanding on such date shall continue to have force and effect in accordance with the provisions of the instruments evidencing such options. 14. NOTICE Any written notice to the Company required by any of the provisions of the Plan shall be addressed to the Treasurer of the Company and shall become effective when it is received. 15. COMPLIANCE WITH RULE 16B-3 Transactions under the Plan are intended to comply with all applicable conditions of Rule 16b-3 or its successor promulgated pursuant to Section 16 of the Securities Exchange Act of 1934.
