9.4 Severability. If any term or provision of this Agreement
is invalid, illegal or incapable of being enforced by rule of law or public
policy, all other conditions and provisions of this Agreement shall nevertheless
remain in full force and effect so long as the economic or legal substance of
the transactions contemplated by this Agreement is not affected in any manner
adverse to any party. Upon such determination that any term or other provision
is invalid, illegal or incapable of being enforced, the parties hereto shall
negotiate in good faith to modify this Agreement so as to effect the original
intent of the parties as closely as possible in an acceptable manner to the end
that the transactions are fulfilled to the extent possible.

9.5 Entire Agreement; Amendment. This Agreement, the Proxy
and any other documents delivered by the parties in connection herewith
constitute the entire agreement between the parties with respect to the subject
matter hereof and thereof and supersede all prior agreements and understandings,
written or oral, between the parties with respect thereto. No amendment or
modification of any provision of this Agreement shall be binding upon either
party unless made in writing and signed by all parties. No agreement,
understanding or arrangement of any nature regarding the subject matter of this

neither this Agreement nor any of the interests or obligations hereunder may be
assigned or delegated by Stockholder, and any attempted or purported assignment
or delegation of any of such interests or obligations in violation of this
Agreement shall be void. Subject to the preceding sentence, this Agreement shall
be binding upon Stockholder and Stockholder’s successors and assigns, and, if
Stockholder is an individual, Stockholder’s heirs, estate, executors and
personal representatives. This Agreement shall inure to the benefit of Parent
and its successors and assigns. Without limiting any of the restrictions set
forth in Section 2 or elsewhere in this Agreement, this Agreement shall be
binding upon any Person to whom any Subject Securities are transferred. Nothing
in this Agreement, expressed or implied, is intended to confer on any Person,
other than the parties hereto, any rights or remedies of any nature.

9.7 Independence of Obligations. The covenants and
obligations of Stockholder set forth in this Agreement shall be construed as
independent of any other agreement or arrangement between Stockholder, on the
one hand, and the Company or Parent, on the other. The existence of any claim or
cause of action by Stockholder against the Company or Parent shall not
constitute a defense to the enforcement of any of such covenants or obligations
against Stockholder.

9.8 Specific Performance. The parties hereto acknowledge
that money damages would be an inadequate remedy for any breach of this
Agreement by any party hereto, and that the obligations of the parties hereto
shall be enforceable by any party hereto through injunctive or other equitable
relief.

9.9 Governing Law. This Agreement shall be governed by, and
construed and enforced 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.

9.10 Counterparts. This Agreement may be executed in
separate counterparts, each of which when so executed and delivered shall be an
original, but all such counterparts shall together constitute one and the same
instrument. The exchange of a fully executed Agreement (in counterparts or
otherwise) by facsimile or by electronic delivery shall be sufficient to bind
the parties to the terms of this Agreement.

9.11 Waiver. No failure on the part of Parent to exercise
any power, right, privilege or remedy under this Agreement, and no delay on the
part of Parent in exercising any power, right, privilege or remedy under this
Agreement, shall operate as a waiver of such power, right, privilege or remedy;
and no single or partial exercise of any such power, right, privilege or remedy
shall preclude any other or further exercise thereof or of any other power,
right, privilege or remedy. Parent shall not be deemed to have

-7-

---

waived any claim available to Parent arising out of this Agreement, or any
power, right, privilege or remedy of Parent under this Agreement, unless the
waiver of such claim, power, right, privilege or remedy is expressly set forth
in a written instrument duly executed and delivered on behalf of Parent; and any
such waiver shall not be applicable or have any effect except in the specific
instance in which it is given.

9.12 Termination. This Agreement and all rights and
obligations of the parties hereunder, including the Proxy, shall terminate, and
no party shall have any rights or obligations hereunder and this Agreement shall
become null and void on, and have no further effect as of the Proxy Expiration
Date. Nothing in this Section 9.12 shall relieve any party from any liability
for any breach of this Agreement prior to its termination.

9.13 Directors and Officers. This Agreement applies to
Stockholder solely in such Stockholder’s capacity as a holder of Subject
Securities, and not to Stockholder or any representative of Stockholder serving
as a director or officer of the Company in such capacity.

singular number shall include the plural, and vice versa; the masculine gender
shall include the feminine and neuter genders; the feminine gender shall include
the masculine and neuter genders; and the neuter gender shall include masculine

ambiguities are to be resolved against the drafting party shall not be applied
in the construction or interpretation of this Agreement.
