       deposit any of the Subject Shares into a voting trust or enter into any
       voting agreement or arrangement with respect to any of the Subject
       Shares, or (iii) take any action that would cause any representation or
       warranty of the Stockholder contained herein or any representation or
       warranty of Parent contained in the Merger Agreement to be untrue or
       incorrect or that would have the effect of preventing or disabling the
       Stockholder from performing the Stockholder's obligations under this
       Agreement.

              (c) The Stockholder shall not, and shall cause each member of the

       to Parent or (ii) directly or indirectly participate in any discussions
       or negotiations regarding, or furnish to any person any information with
       respect to, or take any other action to facilitate any inquiries or the
       making of any proposal that constitutes or may reasonably be expected to
       lead to, any Takeover Proposal with respect to Parent or (iii) vote (or
       cause to be voted) the Subject Shares in favor of any such Takeover
       Proposal.

       Parent or any of its Subsidiaries, securities or assets which is not
       endorsed in writing by the Company and (ii) any other action or agreement
       that would result in a breach of any covenant, representation or warranty
       or any other obligation or agreement of Parent under the Merger Agreement
       or that could result in any of the conditions to Parent's obligations
       under the Merger Agreement not being fulfilled.

              (e) The Stockholder shall cooperate with the Company to support
       and to consummate and make effective, in the most expeditious manner

              (b) This Agreement has been duly executed and delivered by the
       Stockholder. Assuming the due authorization, execution and delivery of
       this Agreement by the Company, this Agreement constitutes the valid and
       binding agreement of the Stockholder enforceable against the Stockholder
       in accordance with its terms, except as may be limited by applicable
       bankruptcy, insolvency, reorganization, moratorium and other similar laws
       of general application which may affect the enforcement of creditors'
       rights generally and by general equitable principles. The execution and
       delivery of this Agreement by the Stockholder does not and will not
       conflict with any agreement, order or other instrument binding upon the
       Stockholder, nor require the Stockholder to make or obtain any regulatory
       filing or approval.

       3. TERMINATION. The obligations of the Stockholder hereunder shall
terminate upon the earlier of the termination of the Merger Agreement pursuant
to Section 10.1 thereof or the Effective Time; PROVIDED, that in the event the
Merger Agreement is terminated pursuant to Section 10.1(b)(ii)(B) or 10.1(f)
thereof, the obligations of the Stockholder hereunder shall terminate 90 days
following the termination of the Merger Agreement. No such termination shall
relieve the Stockholder from any liability in connection with this Agreement
incurred prior to such termination.

       4. FURTHER ASSURANCES. The Stockholder will, from time to time, execute
and deliver, or cause to be executed and delivered, such additional or further
consents, documents and other instruments as the Company may reasonably request
for the purpose of effectively carrying out the transactions contemplated by
this Agreement.

       5. SUCCESSORS, ASSIGNS AND TRANSFEREES BOUND. Any successor, assignee or
transferee (including a successor, assignee or transferee as a result of the
death of the Stockholder, such as an executor or heir) shall be bound by the
terms hereof, and the Stockholder shall take any and all actions necessary to
obtain and deliver to the Company the written confirmation from such successor,
assignee or transferee that it is bound by the terms hereof.

       6. REMEDIES. The Stockholder acknowledges that money damages would be
both incalculable and an insufficient remedy for any breach of this Agreement by
it, and that any such breach would cause the Company irreparable harm.
Accordingly, the Stockholder agrees that in the event of any breach or
threatened breach of this Agreement, the Company, in addition to any other
remedies at law or in equity it may have, shall be entitled, without the
requirement of posting a bond or other security, to equitable relief, including
injunctive relief and specific performance.

       7. SEVERABILITY. The invalidity or unenforceability of any provision of
this Agreement in any jurisdiction shall not affect the validity or
enforceability of any other provision of this Agreement in such jurisdiction, or
the validity or enforceability of any provision of this Agreement in any other
jurisdiction.

       8. AMENDMENT. This Agreement may be amended only by means of a written
instrument executed and delivered by both the Stockholder and the Company.

       9. GOVERNING LAW. This Agreement shall be governed by, and construed in
accordance with, the laws of the State of Delaware, regardless of the laws that
might otherwise govern under applicable principles of conflicts of laws thereof.

       10. CAPITALIZED TERMS. Capitalized terms used in this Agreement that are
not defined herein shall have such meanings as set forth in the Merger
Agreement.

       11. COUNTERPARTS. For the convenience of the parties, this Agreement may
be executed in counterparts, each of which shall be deemed an original, but all
of which together shall constitute one and the same instrument.

       12. NO LIMITATION ON ACTIONS OF AN AFFILIATE OR ASSOCIATE OF THE
STOCKHOLDER AS DIRECTOR. In the event an affiliate or associate of the
Stockholder is a director of Parent, notwithstanding anything to the contrary in
this Agreement, nothing in this Agreement is intended or shall be construed to
require such individual to take or in any way limit any action that such
individual may take to discharge such individual's fiduciary duties as a
director of Parent.
