5.3           Amendments; Waivers. No provision of this Agreement may be waived or amended except in a written instrument signed, in
the case of an amendment, by the Company and the Purchaser or, in the case of a waiver, by the Party
against whom enforcement of any such waiver is sought. No waiver of any default with respect to any
provision, condition or requirement of this Agreement shall be deemed to be a continuing waiver in
the future or a waiver of any subsequent default or a waiver of any other provision, condition or
requirement hereof, nor shall any delay or omission of either party to exercise any right hereunder
in any manner impair the exercise of any such right.
5.4           Construction. The headings herein are for convenience only, do not constitute a part of this Agreement and shall
not be deemed to limit or affect any of the provisions hereof. The language used in this Agreement
will be deemed to be the language chosen by the parties to express their mutual intent, and no rules
of strict construction will be applied against any party. This Agreement shall be construed as if
drafted jointly by the parties, and no presumption or burden of proof shall arise favoring or disfavoring
any party by virtue of the authorship of any provisions of this Agreement.
5.5           Successors and Assigns. This Agreement shall be binding upon and inure to the benefit of the parties and their successors
and permitted assigns. Neither party may assign this Agreement or any rights or obligations hereunder
without the prior written consent of the other party.

|5.6           No Third-Party Beneficiaries. This Agreement is intended for the benefit of the parties hereto and their respective successors
and permitted assigns and is not for the benefit of, nor may any provision hereof be enforced by,
any other Person.
5.7           Governing Law. All questions concerning the construction, validity, enforcement and interpretation of this Agreement
shall be governed by and construed and enforced in accordance with the internal laws of the State
of New York, without regard to the principles of conflicts of law thereof. Each party agrees that
all Proceedings concerning the interpretations, enforcement and defense of the transactions contemplated
by this Agreement (whether brought against a party hereto or its respective Affiliates, employees
or agents) shall be commenced exclusively in the state and federal courts sitting in the City of
New York, Borough of Manhattan (the New York Courts). Each party hereto hereby irrevocably submits to the exclusive jurisdiction of the New York
Courts for the adjudication of any dispute hereunder or in connection herewith or with any transaction
contemplated hereby or discussed herein, and hereby irrevocably waives, and agrees not to assert
in any Proceeding, any claim that it is not personally subject to the jurisdiction of any such New
York Court, or that such Proceeding has been commenced in an improper or inconvenient forum. Each
party hereto hereby irrevocably waives personal service of process and consents to process being
served in any such Proceeding by mailing a copy thereof via registered or certified mail or overnight
delivery (with evidence of delivery) to such party at the address in effect for notices to it under
this Agreement and agrees that such service shall constitute good and sufficient service of process
and notice thereof. Nothing contained herein shall be deemed to limit in any way any right to serve
process in any manner permitted by law. Each party hereto hereby irrevocably waives, to the fullest
extent permitted by applicable law, any and all right to trial by jury in any legal proceeding arising
out of or relating to this Agreement or the transactions contemplated hereby. If either party shall
commence a Proceeding to enforce any provisions of this Agreement, then the prevailing party in such
Proceeding shall be reimbursed by the other party for its attorneys fees and other costs and
expenses incurred with the investigation, preparation and prosecution of such Proceeding.
5.8           Survival. The representations, warranties, agreements and covenants contained herein shall survive the Closing
Date and the delivery of the Shares.
5.9           Execution. This Agreement may be executed in two or more counterparts, all of which when taken together shall
be considered one and the same agreement and shall become effective when counterparts have been signed
by each party and delivered to the other party, it being understood that both parties need not sign
the same counterpart. In the event that any signature is delivered by facsimile transmission, such
signature shall create the valid and binding obligation of the party executing (or on whose behalf
such signature is executed) with the same force and effect as if such facsimile signature page were
an original thereof.
5.10         Severability. If any provision of this Agreement is held to be invalid or unenforceable in any respect, the validity
and enforceability of the remaining terms and provisions of this Agreement shall not in any way be
affected or impaired thereby and the parties will attempt to agree upon a valid and enforceable provision
that is a reasonable substitute therefor, and upon so agreeing, shall incorporate such substitute
provision in this Agreement.
