Section 7.4

This Agreement shall be governed by and construed in accordance with the laws of the State of New York, United States of America, without giving effect to the conflicts of laws principles thereof other than Sections 5-1401 and 5-1402 of the General Obligations Law of the State of New York.

(a)

The Financing Documents, and any rights of the Lenders arising out of or relating to any Financing Documents, may, at the option of the Lenders, be enforced by the Lenders in the courts of the United States of America located in the Southern District of the State of New York or in any other courts having jurisdiction. For the benefit of the Lenders, the Borrower hereby irrevocably agrees that any legal action, suit or other proceeding arising out of any Financing Document may be brought in the courts of the State of New York or of the United States of America for the Southern District of New York. By the execution and delivery of this Agreement, the Borrower hereby irrevocably consents and submits to the jurisdiction of any such court in any such action, suit or other proceeding. Final judgment against the Borrower in any such action, suit or other proceeding sh all be conclusive and may be enforced in any other jurisdiction by suit on the judgment. Nothing contained in any Financing Document shall affect the right of the Lenders to commence legal proceedings or otherwise sue the Borrower in any court having jurisdiction, or concurrently in more than one jurisdiction, or to serve process, pleadings and other legal papers upon the Borrower in any manner authorized by the laws of any such jurisdiction.

(b)

The Borrower irrevocably waives, to the fullest extent permitted by applicable law, any objection which it may now or hereafter have to the laying of venue of any action, suit or other proceeding arising out of or relating to any Financing

Document, brought in the courts of the State of New York or in the United States District Court for the Southern District of New York, and any claim that any such action, suit or other proceeding brought in any such court has been brought in an inconvenient forum.

(c)

The Borrower hereby waives any and all rights to demand a trial by jury in any action, suit or other proceeding arising out of any Financing Document or the transactions contemplated by any Financing Document.

(d)

To the extent that the Parties may, in any suit, action or other proceeding brought in any court arising out of or in connection with any Financing Document, be entitled to the benefit of any provision of law requiring the Borrower or the Lenders, as applicable, in such suit, action or other proceeding to post security for the costs of the Borrower or the Lenders, as applicable, or to post a bond or to take similar action, the Parties hereby irrevocably waive such benefit, in each case to the fullest extent now or hereafter permitted under any applicable laws.

Section 7.5

Successor and Assigns.

(a)

This Agreement shall bind and inure to the respective successors and assigns of the Parties, except that the Borrower may not assign or otherwise transfer all or any part of its rights or obligations under this Agreement without the prior written consent of the Lenders.

(b)

With respect to the Loans made by the Offshore Lenders, an Affiliate of the Lender shall maintain, as agent to, and on behalf of the Borrower, a register for the recordation of the names and addresses of each assignee and the principal amount of the Loans owing to each Offshore Lender and each assignee from time to time (the “Register”). The entries in the Register shall be conclusive and binding for all purposes, absent manifest error, and the Borrower and each Offshore Lender may treat each Person whose name is recorded in the Register as a “Lender” hereunder for the purposes of this Agreement. The Register shall be available for inspection by the Borrower and each Offshore Lender at any reasonable time and from time to time upon reasonable prior notice. Until an Offshore Lender has notified the Borrower that a Note has been assigned and that the assignee’s name and address and the principal amount of the Loans being assigned have been recorded in the Register, the Borrower shall recognize the relevant Offshore Lender as the “Lender” with respect to such Loans.

(c)

Any attempted assignment or participation in violation of this Section 7.5 shall be void and of no force and effect. Until there has been a valid assignment of this Agreement and of all of the rights hereunder by a Lender in accordance with this Section 7.5, the Borrower

shall deem and treat such Lender as the absolute beneficial owner and holder of this Agreement and of all of the rights hereunder for all purposes.

Section 7.6

Entire Agreement. The Financing Documents contain the entire understanding of the Parties with respect to the matters covered thereby and supersede any and all other written and oral communications, negotiations, commitments and writings with respect thereto. The provisions of this Agreement may be waived, modified, supplemented or amended only by an instrument in writing signed by the authorized officer of each Party.

Section 7.7

Amendments. Any provision of this Agreement may be amended or waived if, but only if, such amendment or waiver is in writing and is signed by the Parties.

Section 7.8

Severability. If any one or more of the provisions contained in this Agreement shall be invalid, illegal or unenforceable in any respect under any law, the validity, legality and enforceability of the remaining provisions shall not in any way be affected or impaired thereby. The Parties shall endeavor in good faith negotiations to replace the invalid, illegal or unenforceable provisions with valid provisions the economic effect of which comes as close as possible to that of the invalid, illegal or unenforceable provisions.

Section 7.9

Counterparts. This Agreement may be executed in several counterparts, and by each Party on separate counterparts, each of which shall be deemed an original, but all of which together shall constitute one and the same agreement.

Section 7.10

Survival.

(a)

This Agreement and all agreements, representations and warranties made in the Financing Documents, and in any document, certificate or statement delivered pursuant thereto or in connection therewith shall be considered to have been relied upon by the other Parties and shall survive the execution and delivery of this Agreement and the making of the Loan hereunder regardless of any investigation made by any such other Party or on its behalf, and shall continue in force until all amounts payable under the Financing Documents shall have been fully paid in accordance with the provisions hereof and thereof, and the Lenders shall not be deemed to have waived, by reason of making the Loan, any Default that may arise by reason of such representation or warranty proving to have been false or misleading, notwithstanding that the Lenders may have had notice or knowledge of any such Def ault or may have had notice or knowledge that such representation or warranty was false or misleading at the time any Disbursement was made hereunder.

(b)

The obligations of the Borrower under Sections 2.6 and 2.7 and the obligations of the Borrower and the Lenders under this Article VII hereof shall survive and remain in full force and effect regardless of the consummation of the transactions contemplated hereby, the repayment of the Loan, or the termination of this Agreement or any provision hereof.

Section 7.11

Waiver. Neither the failure of, nor any delay on the part of, any Party in exercising any right, power or privilege hereunder, or under any agreement, document or instrument mentioned herein, shall operate as a waiver thereof, nor shall any single or partial

exercise of any right, power or privilege hereunder, or under any agreement, document or instrument mentioned herein, preclude other or further exercise thereof or the exercise of any other right, power or privilege; nor shall any waiver of any right, power, privilege or default hereunder, or under any agreement, document or instrument mentioned herein, constitute a waiver of any other right, power, privilege or default or constitute a waiver of any default of the same or of any other term or provision. No course of dealing and no delay in exercising, or omission to exercise, any right, power or remedy accruing to the Lenders upon any default under this Agreement, or any other agreement shall impair any such right, power or remedy or be construed to be a waiver thereof or an acquiescence therein; nor shall the action of the Lenders in respect of any such default, or any acquiescence b y it therein, affect or impair any right, power or remedy of the Lenders in respect of any other default. All rights and remedies herein provided are cumulative and not exclusive of any rights or remedies otherwise provided by law.

Section 7.12

Indemnity.

(a)

The Parties shall, at all times, indemnify and hold each other harmless (the “Indemnity”) and each of their respective directors, partners, officers, employees, agents, counsel and advisors (each, an “Indemnified Person”) in connection with any losses, claims (including the cost of defending against such claims), damages, liabilities, penalties, or other expenses arising out of, or relating to, the Financing Documents, the extension of credit hereunder or the Loan or the use or intended use of the Loan, which an Indemnified Person may incur or to which an Indemnified Person may become subject (each, a “Loss”). The Indemnity shall not apply to the extent that a court or arbitral tribunal with jurisdiction over the subject matter of the Loss, and over the Lenders or the Borrower, as applicable, and such other Indemnified Pers on that had an adequate opportunity to defend its interests, determines that such Loss resulted from the gross negligence or willful misconduct of the Indemnified Person, which determination results in a final, non-appealable judgment or decision of a court or tribunal of competent jurisdiction. The Indemnity is independent of and in addition to any other agreement of any Party under any Financing Document to pay any amount to the Lenders or the Borrower, as applicable, and any exclusion of any obligation to pay any amount under this subsection shall not affect the requirement to pay such amount under any other section hereof or under any other agreement.

(b)

Without prejudice to the survival of any other agreement of any of the Parties hereunder, the agreements and the obligations of the Parties contained in this Section 7.12 shall survive the termination of each other provision hereof and the payment of all amounts payable to the Lenders hereunder.

Section 7.13

No Usury. The Financing Documents are hereby expressly limited so that in no contingency or event whatsoever, whether by reason of acceleration or otherwise, shall the amount paid or agreed to be paid to the Lenders for the Loan exceed the maximum amount permissible under applicable law. If from any circumstance whatsoever fulfillment of any provision hereof, at the time performance of such provision shall be due, shall involve transcending the limit of validity prescribed by law, then, ipso facto, the obligation to be fulfilled shall be reduced to the limit of such validity, and if from any such circumstance the Lenders shall ever receive anything which might be deemed interest under applicable law, that would exceed

the highest lawful rate, such amount that would be deemed excessive interest shall be applied to the reduction of the principal amount owing on account of the Loan, or if such deemed excessive interest exceeds the unpaid balance of principal of the Loan, such deemed excess shall be refunded to the Borrower. All sums paid or agreed to be paid to the Lenders for the Loan shall, to the extent permitted by applicable law, be deemed to be amortized, prorated, allocated and spread throughout the full term of the Loan until payment in full so that the deemed rate of interest on account of the Loan is uniform throughout the term thereof. The terms and provisions of this paragraph shall control and supersede every other provision of this Agreement and the Notes.

Section 7.14

Further Assurances. From time to time, the Borrower shall perform any and all acts and execute and deliver to the Lenders such additional documents as may be necessary or as requested by the Lenders to carry out the purposes of any Financing Document or any or to preserve and protect the Lenders’ rights as contemplated therein.

Section 7.15

Termination. Subject to the provisions of Section 7.10(b), upon repayment of all outstanding principal of the Loan (together with any other amounts accrued and unpaid under this Agreement), the Borrower may terminate this Agreement upon 10 days’ notice to the Lenders.
