The amount of the Commitment may be reduced, on a dollar-for-dollar basis, in the event, and to the extent, that Parent has, as of immediately prior to the Closing, adequate cash amounts to fully finance the Transactions (including fees and expenses related thereto) and does not require all of the equity financing contemplated by the Commitment for such purposes.

4.

7.

8. Under no circumstances shall any Equity Investor Related Person, Parent or Merger Sub be liable for special, incidental, consequential, exemplary or punitive damages under or in connection with the Agreement, this letter agreement or the transactions contemplated or otherwise incidental thereby or hereby; provided, that the foregoing shall in no way limit the Company’s right to specific performance in the Agreement against Parent and/or Merger Sub (subject to the terms and limitations in Section 9.9 of the Agreement) or receive the Parent Termination Fee from Parent if and when required to be paid pursuant to the Agreement, together with any amounts payable pursuant to Section 8.4(g) of the Agreement, or otherwise limit the Company’s rights under the Limited Guarantee.

9. This letter agreement may not be amended except by an instrument in writing signed by each of the parties hereto and the Company.

10. This letter agreement, and all claims or causes of action (whether at Law, in contract or in tort or otherwise) that may be based upon, arise out of or relate to this letter agreement, or the negotiation, execution or performance of this letter agreement, shall be governed by and construed in accordance with the laws of the State of Delaware, without giving effect to the principles of conflicts of law thereof; provided, however, that issues involving the consummation and effects of the Merger will be governed by the laws of the State of Nevada to the extent the application of Nevada law is mandatory. The parties hereto irrevocably submit to the jurisdiction of the Court of Chancery of the State of Delaware or, if the Court of Chancery of the State of Delaware lacks jurisdiction over such matter, the Superior Court of the State of Delaware and the federal courts of the United States of America located in the State of Delaware, in connection with any dispute that arises in respect of this letter agreement, and hereby waive, and agree not to assert, as a defense in any action, suit or proceeding for interpretation or enforcement hereof or any such document that it is not subject thereto or that such action, suit or proceeding may not be brought or is not maintainable in said courts or that venue thereof may not be appropriate or that this letter agreement may not be enforced in or by such courts, and the parties hereto irrevocably agree that all claims with respect to such action, suit or proceeding shall be heard and determined exclusively by such a Delaware state or federal court. The parties hereto hereby consent to and grant any such court jurisdiction over the person of such parties and over the subject matter of such dispute and agree that mailing of process or other papers in connection with such action, suit or proceeding in such manner as may be permitted by Law shall be valid and sufficient service thereof.

11. EACH PARTY HERETO ACKNOWLEDGES AND AGREES THAT ANY CONTROVERSY THAT MAY ARISE UNDER THIS LETTER AGREEMENT IS LIKELY TO INVOLVE COMPLICATED AND DIFFICULT ISSUES, AND THEREFORE EACH PARTY HEREBY IRREVOCABLY AND UNCONDITIONALLY WAIVES ANY RIGHT SUCH PARTY MAY HAVE TO A TRIAL BY JURY IN RESPECT OF ANY LITIGATION DIRECTLY OR INDIRECTLY ARISING OUT OF OR RELATING TO THIS LETTER AGREEMENT OR THE TRANSACTIONS CONTEMPLATED HEREBY. EACH PARTY CERTIFIES AND ACKNOWLEDGES THAT (I) NO REPRESENTATIVE, AGENT OR ATTORNEY OF ANY OTHER PARTY HAS REPRESENTED, EXPRESSLY OR OTHERWISE, THAT SUCH OTHER PARTY WOULD NOT, IN THE EVENT OF LITIGATION, SEEK TO ENFORCE THE FOREGOING WAIVER; (II) SUCH PARTY UNDERSTANDS AND HAS CONSIDERED THE IMPLICATIONS OF THE FOREGOING WAIVER; (III) SUCH PARTY MAKES THE FOREGOING WAIVER VOLUNTARILY AND (IV) SUCH PARTY HAS BEEN INDUCED TO ENTER INTO THIS LETTER AGREEMENT BY, AMONG OTHER THINGS, THE MUTUAL WAIVER AND CERTIFICATIONS IN THIS SECTION 11.

12. This letter agreement shall be treated as confidential and is being provided to the Company solely in connection with the Transactions. This letter agreement may not be used, circulated, quoted or otherwise referred to in any document (other than the Agreement and the Limited Guarantee), except with the written consent of the Equity Investor; provided, however, that the Company, Parent, Merger Sub and the Equity Investor may disclose this letter agreement (a) to the extent required by applicable Law, (b) to the other Equity Investor Related Persons, (c) to the financing sources of the Equity Investor Related Persons, (d) to the respective officers, directors, employees, advisors, representatives, and agents of the foregoing (including the Company, Parent, Merger Sub and the Equity Investor) and (e) in connection with any dispute involving any party hereto or the Company regarding this letter agreement or the transactions contemplated by this letter agreement.

13. Together with the Agreement and the Limited Guarantee, this letter agreement constitutes the sole agreement, and supersedes all prior agreements, understandings and statements, written or oral, between the Equity Investor and Parent, and any other person with respect to the matters contemplated by this letter agreement.

14. The Equity Investor hereby represents and warrants to the Company and Parent that: (a) the execution, delivery and performance of this letter agreement by the Equity Investor have been duly authorized by all necessary action under and do not contravene any provision of the Equity Investor’s partnership agreement or similar organizational documents or any other contract to which the Equity Investor is a party or otherwise subject or contravene any applicable Law or contractual restriction binding on the Equity Investor or its assets; (b) all consents, approvals, authorizations, permits of, filings with and notifications to, any Governmental Entity necessary for the due execution, delivery and performance of this letter agreement by the Equity Investor have been obtained or made and all conditions thereof have been duly complied with, and no other action by, and no notice to or filing with, any Governmental Entity is required in connection with the execution, delivery or performance of this letter agreement; (c) this letter agreement has been duly and validly executed and delivered by it and constitutes a legal, valid and binding obligation of the Equity Investor enforceable against such Equity Investor in accordance with its terms (except insofar as such enforceability may be limited by bankruptcy, insolvency, reorganization, moratorium or other Laws of general applicability relating to or affecting creditors’ rights, or by principles governing the availability of equitable remedies, whether considered in an Action at law or in equity); (d) the Equity Investor has, and until the termination of this letter agreement in accordance with the terms hereof, the financial capability and uncalled capital commitments necessary to fulfill its Commitment and all funds necessary for the Equity Investor to fulfill its obligations under the Commitment shall be available to the Equity Investor; and (e) it has all limited partnership power and authority to execute, deliver and perform this letter agreement.

15. The Equity Investor agrees that irreparable damage would occur in the event that any of the provisions of this letter agreement were not performed in accordance with their specific terms or were otherwise breached. It is accordingly agreed that, in addition to any other remedy that Parent may have under law or in equity, in the event of any breach or threatened breach by the Equity Investor, of any covenant or obligation of such party contained in this letter agreement, Parent shall be entitled to (a) a decree or order of specific performance to enforce the observance and performance of such covenant and (b) an injunction restraining such breach or threatened breach. In the event that any action is brought in equity to enforce the provisions of this letter agreement, the Equity Investor shall not allege, and the Equity Investor hereby waives the defense or counterclaim, that there is an adequate remedy at law. The Equity Investor further agrees that neither Parent nor any other Person shall be required to obtain, furnish, or post any bond or similar instrument in connection with or as a condition to obtaining any remedy referred to in this Section 15, and the Equity Investor irrevocably waives any right it may have to require the obtaining, furnishing, or posting of any such bond or similar instrument.
