This Agreement, the exhibits and schedules hereto, and the other documents delivered pursuant hereto constitute the full and entire understanding and agreement between the parties with regard to the subjects hereof and no party shall be liable for or bound to any other in any manner by any oral or written representations, warranties, covenants and agreements except as specifically set forth herein.

8.7 Severability. In the event one or more of the provisions of this Agreement should, for any reason, be held to be invalid, illegal or unenforceable in any respect, such invalidity, illegality or unenforceability shall not affect any other provisions of this Agreement, and this Agreement shall be construed as if such invalid, illegal or unenforceable provision had never been contained herein. Upon such determination that any provision of this Agreement, or the application of any such provision, is invalid, illegal, void or unenforceable, the Company and the Purchaser shall negotiate in good faith to modify this Agreement so as to effect the original intent of the Company and the Purchaser as closely as possible to the fullest extent permitted by Law in an acceptable manner to the end that the transactions contemplated hereby are fulfilled to the greatest extent possible.

8.8 Amendment. No provision in this Agreement shall be supplemented, deleted or amended except in a writing executed by an authorized representative of each of the Purchaser and the Company. Any amendment effected in accordance with this Section 8.8 shall be binding upon each holder of Shares purchased under this Agreement at the time outstanding, each future holder of all such Shares, and the Company, and any amendment not effected in accordance with this Section 8.8 shall be void and of no effect.

8.9 Waivers; Delays or Omissions. It is agreed that no delay or omission to exercise any right, power or remedy accruing to any party, upon any breach, default or noncompliance by another party under this Agreement, shall impair any such right, power or remedy, nor shall it be construed to be a waiver of any such breach, default or noncompliance, or any acquiescence therein, or of or in any similar breach, default or noncompliance thereafter occurring. It is further agreed that any Consent of any kind or character on any party’s part of any breach, default or noncompliance under this Agreement or any waiver on such party’s part of any provisions or conditions of the Agreement must be in writing and shall be effective only to the extent specifically set forth in such writing. All remedies, either under this Agreement, by Law, or otherwise afforded to any party, shall be cumulative and not alternative. Any waiver effected in accordance with this Section 8.9 shall be binding upon each holder of Shares purchased under this Agreement at the time outstanding, each future holder of all such Shares, and the Company, and any waiver not effected in accordance with this Section 8.9 shall be void and of no effect.

8.10 Equitable Relief. Each of the Company and the Purchaser hereby acknowledges and agrees that the failure of the Company to perform its respective agreements and covenants hereunder will cause irreparable injury to the Purchaser, for which damages, even if available, will not be an adequate remedy. Accordingly, the Company hereby agrees that the Purchaser shall be entitled to seek the issuance of equitable relief by any court of competent jurisdiction to compel performance of the Company’s obligations.

All notices and other communications under this Agreement must be in writing and are deemed duly delivered when (a) delivered if delivered personally or by nationally recognized overnight courier service (costs prepaid), (b) sent by facsimile or email with confirmation of transmission by the transmitting equipment and receipt or (c) received or rejected by the addressee, if sent by United States of America certified or registered mail, return receipt requested; in each case to the following addresses, email addresses or facsimile numbers and marked to the attention of the individual (by name or title) designated below (or to such other address, email address, facsimile number or individual as a party may designate by notice to the other parties):
