Provided that none of the executive officers of the Corporation has actual knowledge of any Solicitation (as hereinafter defined) relating to the Corporation on the date hereof which Solicitation is not publicly supported by a resolution of a majority of the current members of the Board of Directors of the Corporation (a "Dissident Solicitation"), each of the Stockholders, for the benefit of the Corporation and as an inducement to the Corporation to enter into this Agreement, agrees to vote or cause to be voted at the 1997 Meeting all of the shares of Common Stock which he or she has the right to vote and of which he or she has the right to direct the vote in favor of persons (the "Continuing Director Nominees") who shall be nominated as directors by a majority of the current directors of the Corporation. Immediately upon any of the executive officers of the Corporation obtaining actual knowledge of any Dissident Solicitation, the Corporation shall inform the Stockholder Representative of such Dissident Solicitation. The terms "Solicitation" and "Solicit" shall mean (i) any solicitation (within the 2 2 meaning of the Exchange Act) of a proxy (as defined in the Exchange Act), (ii) any request for a proxy, whether or not accompanied, preceded or followed by a proxy or included in a form of proxy, (iii) any request or recommendation to execute or not to execute, or to revoke or not to revoke, a proxy, (iv) the furnishing of a form of proxy or other communication to security holders under circumstances reasonably calculated to result in the procurement, withholding or revocation of a proxy or (v) any public statement, favorable or unfavorable, regarding any proposal, nominee or other matter in any proxy. 2. The 13D Director. (a) Provided that (i) none of the Stockholders shall have breached any of their agreements hereunder and (ii) there shall not have been a Dissident Solicitation, then the Corporation shall use its best efforts to cause the Board of Directors of the Corporation (x) to increase by one the number of Class C directors of the Corporation and to elect John P. Mahoney, M.D. (the "13D Director") as a Class C director of the Corporation at a meeting of the Board of Directors to be held within 24 hours of the adjournment of the 1997 Meeting and (y) to nominate the 13D Director for reelection as a Class C director at the 1998 annual meeting of the Corporation's stockholders. Attached hereto as Annex A is a form of the agreement of the current directors of the Corporation concerning this Section 2; such form of agreement, executed by a majority of the current directors of the Corporation, is being delivered to the Stockholders contemporaneously herewith. (b) Notwithstanding the foregoing, if the Stockholders shall at any time beneficially own (within the meaning of Rule 13d-3 under the Exchange Act) in the aggregate less than five percent (5%) of the shares of Common Stock outstanding or 460,270 shares of Common Stock, whichever is less, then the Stockholders shall have no further rights under this Section 2 and the 13D Director shall promptly resign as a director of the Corporation.

The amendment to the By-laws of the Corporation set forth on Annex C hereto will be proposed for adoption at the next meeting of the Board of Directors of the Corporation. Each of the Stockholders agrees that such amendment is appropriate and agrees not to oppose or challenge its adoption. 3 3 4. Appointment of Stockholder Representative. (a) Each Stockholder hereby makes, constitutes and appoints John P.

The incapacity of any Stockholder shall not terminate the agency and power of attorney granted hereby to the Stockholder Representative. Upon the death of any Stockholder, such Stockholder's executors, administrators, legal representatives and heirs may only exercise rights under this Agreement through the Stockholder Representative as their sole and exclusive agent. Such agency and power of attorney is irrevocable and coupled with an interest, and the provisions of this Section 4 are independent and severable and shall be enforceable notwithstanding any rights or remedies that any Stockholder may have in connection with, or in any way arising out of, the transactions contemplated by this Agreement. The obligations hereunder of Dr. Mahoney, as representative, shall not be terminated by operation of law, whether by his death or incapacity or by the occurrence of any other event. In the event Dr. Mahoney should die or become incapacitated, or for any other reason become unable to perform his responsibilities hereunder, or resign such position, the Stockholders holding a majority of the shares of Common Stock held by all Stockholders shall select another representative by written notice executed by such Stockholders and delivered to the Corporation to fill such vacancy and such substituted representative shall be deemed the Stockholder Representative for all purposes of this Agreement. (b) The Corporation shall be entitled to rely conclusively on the actions, communications, instructions, decisions and agreements of the Stockholder Representative as being the actions, communications, instructions, decisions and agreements of each of the Stockholders (without the need to communicate or otherwise confirm such with any Stockholder), and no Stockholder shall have any claim or cause of action against the Corporation for any action taken or not taken by the Corporation in reliance 4 4 upon the actions, communications, instructions, decisions or agreements of the Stockholder Representative. (c) All actions, communications, instructions, decisions and agreements of the Stockholder Representative shall be conclusive and binding upon all of the Stockholders and no Stockholder shall have any claim or cause of action against the Stockholder Representative for any action taken or not taken by the Stockholder Representative in his role as such, except for any action or omission taken or made fraudulently or in bad faith with respect to such Stockholder. 5. No Solicitation. (a) From the date hereof through the date of the 1997 Meeting, none of the Stockholders and none of their respective affiliates or associates shall become, provide information to or assist a Participant (as hereinafter defined) in any Dissident Solicitation.

The terms "affiliate" and "associate" shall have the respective meanings ascribed to such terms in Rule 12b-2 under the Exchange Act, as in effect on the date hereof.
