      (b) At any meeting of stockholders of the Company or at any adjournment
   thereof or in any other circumstances upon which the Stockholder's vote,

   (other than the Merger Agreement and the Merger), consolidation,

   economic transactions do not restrict or otherwise inhibit the Stockholder's
   ability to vote the Subject Shares in accordance with the requirements of
   this Agreement and to otherwise comply with the covenants and agreements of
   the Stockholder contained herein, or (C) the Transfer of any Subject Shares
   to any person who agrees to be bound by the terms and conditions of this

   Shares so tendered prior to the termination of the Offer.

   4.  Grant of Proxy.  (a) The Stockholder hereby irrevocably grants to, and

dissolution, liquidation or winding up of or by the Company or any other
Takeover Proposal, and (iii) against any amendment of the Company's certificate
of incorporation or by-laws or other proposal, transaction or agreement
involving the Company or any of its subsidiaries, which amendment or other
proposal, transaction or agreement would in any manner impede, frustrate,
prevent, delay or nullify the Offer, the Merger, the Merger Agreement or any
other transactions contemplated by the Merger Agreement. Notwithstanding
anything contained herein to the contrary, such irrevocable proxy will not be
exercised by Parent or any of its designees unless the Stockholder breaches its
obligations under Section 4 of this Agreement. No proxy is given hereby with
respect to any matters other than those enumerated above.

      (b) The Stockholder represents and warrants that any proxies heretofore
   given in respect of the Subject Shares are revocable, and that any such
   proxies have been or are hereby revoked.

      (c) The Stockholder hereby affirms that the irrevocable proxy set forth
   in this Section 4 is given in connection with the execution of the Merger
   Agreement and that such irrevocable proxy is given to secure the performance
   of the duties of the Stockholder under this Agreement. The Stockholder
   hereby affirms that the irrevocable proxy set forth in this Section 4 is
   coupled with an interest and is intended to be irrevocable in accordance
   with the provisions of Section 212 of the General Corporation Law of the
   State of Delaware, as amended, prior to the termination of this Agreement.
   Notwithstanding anything contained herein to the contrary, this irrevocable
   proxy shall automatically terminate upon termination of this Agreement.

   5.  Further Assurances.  The Stockholder will, from time to time, take such
actions and execute and deliver, or cause to be executed and delivered, such
additional or further transfers, assignments, endorsements, consents and other
instruments as Parent or Sub may reasonably request for the purpose of
effectively carrying out the transactions contemplated by this Agreement.

   6.  Assignment.  Neither this Agreement nor any of the rights, interests or
obligations hereunder shall be assigned by any of the parties without the prior
written consent of the other parties, except that Sub may assign, in its sole
discretion, any or all of its rights, interests and obligations hereunder to
Parent or to any direct or indirect wholly owned subsidiary of Parent. Subject
to the preceding sentence, this Agreement will be binding upon, inure to the
benefit of and be enforceable by the parties and their respective successors
and assigns and, in the case of the Stockholder, the heirs, executors and
administrators of the Stockholder.
