This Agreement has been duly and validly executed and delivered by the Company, and (assuming the due authorization, execution and delivery of this Agreement by the Seller) this Agreement constitutes a valid and binding obligation of the Company, enforceable against the Company in accordance with its terms, except as enforcement may be limited by general principles of equity whether applied in a court of law or a court of equity and by bankruptcy, insolvency and similar Laws affecting creditors’ rights and remedies generally.

4

(C) Non-Contravention. Neither the execution and delivery of this Agreement nor the consummation by the Company of the transactions contemplated hereby will violate any provision of the charter or bylaws or similar governing documents of the Company or, assuming that the consents, approvals, filings and registrations referred to in Section 3.01(D) are received or made (as applicable), applicable Law.

(D) Consents and Approvals.

7.06. Entire Understanding; No Third Party Beneficiaries. This Agreement (together with the documents, agreements and instruments referred to herein) represents the entire understanding of the parties with respect to the subject matter hereof and supersedes any and all other oral or written agreements heretofore made with respect to the subject matter hereof. Nothing in this Agreement, expressed or implied, is intended to confer upon any person, other than the parties hereto, any rights or remedies hereunder.

7.07. Assignment. Neither this Agreement nor any right, remedy, obligation or liability arising hereunder or by reason hereof shall be assignable by any party hereto without the prior written consent of the other party, and any attempt to assign any right, remedy, obligation or liability hereunder without such consent shall be null and void; provided, however, that the Seller may assign this Agreement to an Affiliate of the Seller.

10

7.08. Severability. Any term or provision of this Agreement which is determined by a court of competent jurisdiction to be invalid, illegal or unenforceable in any jurisdiction shall, as to that jurisdiction, be ineffective to the extent of such invalidity or unenforceability without rendering invalid, illegal or unenforceable the remaining terms and provisions of this Agreement or affecting the validity, legality or enforceability of any of the terms or provisions of this Agreement in any other jurisdiction, and if any provision of this Agreement is determined to be so broad as to be unenforceable, the provision shall be interpreted to be only so broad as is enforceable, in all cases so long as neither the economic nor legal substance of the transactions contemplated hereby is affected in any manner materially adverse to any party or its shareholders. Upon any such determination, the parties shall negotiate in good faith in an effort to agree upon a suitable and equitable substitute provision to effect the original intent of the parties.
