      WHEREAS, in order to induce Parent and Merger Subsidiary to enter into the
Agreement and Plan of Merger dated as of the date hereof with the Company (the

and Stockholder has agreed, to enter into this Agreement;

representations, warranties, covenants and agreements in connection with this
Agreement; and

      WHEREAS, capitalized terms used but not defined herein shall have the
respective meanings ascribed to such terms in the Merger Agreement.

      NOW, THEREFORE, for good and valuable consideration and in consideration
of the foregoing and the mutual covenants and agreements herein contained, the
receipt and sufficiency of which are hereby acknowledged, and intending to be
legally bound hereby, Parent, Merger Subsidiary and Stockholder hereby agree as
follows:

                                    ARTICLE I

      SECTION 1.01 Voting. Stockholder agrees that from the date of this
Agreement until the Expiration Date (as hereinafter defined), at any meeting of
the stockholders of the Company, however called, or in any other circumstance in
which the vote, consent or approval of the stockholders of the Company is
sought, Stockholder shall, or shall cause the record holder(s) of the Subject
Shares (as hereinafter defined), to, subject to Section 1.02 hereof, vote the
Subject Shares (i) in favor of the Merger, the Merger Agreement and otherwise in
favor of the transactions contemplated by the Merger Agreement as such Merger
Agreement may be modified or amended from time to time and (ii) against any
action or agreement that would impede, interfere with, delay, postpone,
discourage or adversely affect the Merger, including, but not limited to, any
agreement or arrangement related to a Competing Transaction. As used herein

defined in Rule 13d-3 under the Exchange Act, which meaning will apply for all
purposes of this Agreement) and/or owned of record by Stockholder and any
additional Shares with respect to which Stockholder becomes the beneficial
and/or record owner after the date of this Agreement. Stockholder authorizes
Parent, Merger Subsidiary and the Company to publish and



disclose in the Company Proxy Statement (including all documents and schedules
filed with the SEC), its identity and ownership of the Subject Shares and the
nature of its commitments, arrangements and understandings under this Agreement.

      SECTION 1.02 Proxy. Stockholder hereby grants to Parent and Merger
Subsidiary, and to each officer of Parent and Merger Subsidiary, a proxy to vote
the Subject Shares as indicated in Section 1.01 hereof. Except as set forth in
the last sentence of this Section 1.02, Stockholder intends this proxy to be,
and this proxy is, irrevocable and coupled with an interest, and Stockholder
will promptly take such further action or execute such other instruments as may
be reasonably requested by Parent to effectuate the intent of this proxy and
hereby revokes any proxy previously granted by Stockholder with respect to the
Subject Shares. Notwithstanding any provision contained in such proxy, such
proxy shall terminate upon the Expiration Date.

                            COVENANTS OF STOCKHOLDER

      SECTION 4.01 Covenants of Stockholder. Stockholder covenants and agrees
with and for the benefit of Parent and Merger Subsidiary as follows:

      (a) Except as expressly contemplated by the terms of this Agreement,
Stockholder shall not:

            (i) until the Expiration Date, sell, transfer, pledge, assign or
      otherwise dispose of, or enter into any contract, option or other
      arrangement or understanding with respect to the sale, transfer, pledge,
      assignment or other disposition of, the Subject Shares to any person,

      Subject Shares to any person, provided such person shall have (A) executed
      a counterpart to this Agreement and (B) agreed to hold such Shares subject

            (ii) until the Expiration Date, enter into, or otherwise subject the
      Subject Shares to, any voting arrangement, whether by proxy, voting
      agreement, voting trust, power-of-attorney or otherwise, with respect to
      the Subject Shares; or

            (iii) until the Expiration Date, take any other action that would in
      any way restrict, limit or interfere with the performance of Stockholder's
      obligations hereunder or the transactions contemplated to be performed by
      Stockholder hereunder.

      (b) Stockholder hereby irrevocably and unconditionally waives, and agrees
not to exercise, and to prevent the exercise of, any rights of appraisal or

or authorize any of its affiliates, agents or representatives to, directly or
indirectly, take any actions prohibited by Section 6.05 of the Merger Agreement
