	    Definitions; Interpretation.

SECTION 5    Governing Law; Submission To Jurisdiction; Waiver Of Jury Trial.
(a)Governing Law. This Amendment and the rights and obligations of the parties hereunder shall be governed by, and construed in accordance with, the law of the State of New York, without regard to principles of conflicts of laws that would result in the application of the laws of any other jurisdiction; provided that Section 5-1401 of the New York General Obligations Law shall apply.


1







(b)Submission to Jurisdiction. Each Obligor agrees that any suit, action or proceeding with respect to this Amendment or any other Loan Document to which it is a party or any judgment entered by any court in respect thereof may be brought initially in the federal or state courts in Houston, Texas or in the courts of its own corporate domicile and irrevocably submits to the non-exclusive jurisdiction of each such court for the purpose of any such suit, action, proceeding or judgment. This Section 5 is for the benefit of the Lenders only and, as a result, no Lender shall be prevented from taking proceedings in any other courts with jurisdiction. To the extent allowed by applicable Laws, the Lenders may take concurrent proceedings in any number of jurisdictions.
(c)Waiver of Jury Trial. Each Obligor and each Lender hereby irrevocably waives, to the fullest extent permitted by applicable law, any and all right to trial by jury in any suit, action or proceeding arising out of or relating to this Amendment, the other Loan Documents or the transactions contemplated hereby or thereby.
SECTION 6    Miscellaneous.
(a)No Waiver. Nothing contained herein shall be deemed to constitute a waiver of compliance with any term or condition contained in the Loan Agreement or any of the other Loan Documents or constitute a course of conduct or dealing among the parties. Except as expressly stated herein, the Lenders reserve all rights, privileges and remedies under the Loan Documents. Except as amended hereby, the Loan Agreement and other Loan Documents remain unmodified and in full force and effect. All references in the Loan Documents to the Loan Agreement shall be deemed to be references to the Loan Agreement as amended hereby.
(b)Severability. In case any provision of or obligation under this Amendment shall be invalid, illegal or unenforceable in any jurisdiction, the validity, legality and enforceability of the remaining provisions or obligations, or of such provision or obligation in any other jurisdiction, shall not in any way be affected or impaired thereby.
(c)Headings. Headings and captions used in this Amendment (including the Exhibits, Schedules and Annexes hereto, if any) are included for convenience of reference only and shall not be given any substantive effect.
(d)Integration. This Amendment constitutes a Loan Document and, together with the other Loan Documents, incorporates all negotiations of the parties hereto with respect to the subject matter hereof and is the final expression and agreement of the parties hereto with respect to the subject matter hereof.
(e)Counterparts. This Amendment may be executed in any number of counterparts, all of which taken together shall constitute one and the same instrument and any of the parties hereto may execute this Amendment by signing any such counterpart.
(f)Controlling Provisions. In the event of any inconsistencies between the provisions of this Amendment and the provisions of any other Loan Document, the provisions of this Amendment shall govern and prevail. Except as expressly modified by this Amendment, the Loan Documents shall not be modified and shall remain in full force and effect. 
(g)Clarifications.  
(i)Borrower and Lenders hereby acknowledge and agree that, in the event that any portion of the Loans becomes due and payable prior to the Stated Maturity Date, whether as a result of acceleration or any other required prepayment event, the “Redemption Date” for purposes of calculating the Prepayment Premium (to the extent due) will be the date of such acceleration or the date of occurrence of the event that triggered such obligation to prepay. 
(ii)Borrower further acknowledges that the Prepayment Premium (as a component of the Redemption Price) and the back-end facility fee specified in the Fee Letter shall be due and payable whenever so stated in the Loan Documents, or by any applicable operation of law, regardless of the circumstances causing any related acceleration or payment prior to the Stated Maturity Date, including without limitation any Event of Default or other failure to comply with the terms of any Loan Document, whether or not notice thereof has been given, or any acceleration by, through, or on account of any bankruptcy filing.
