 (a) Each Obligor hereby represents and
warrants to each Lender as follows: 
 (i) Such Obligor has full power, authority and legal right to make and perform this Amendment and the
Amendment No. 2 Fee Letter. This Amendment and the Amendment No. 2 Fee Letter are within such Obligor’s corporate powers and have been duly authorized by all necessary corporate and, if required, by all necessary shareholder action.
This Amendment and the Amendment No. 2 Fee Letter have been duly executed and delivered by such Obligor and constitute legal, valid and binding obligations of such Obligor, enforceable against such Obligor in accordance with their terms, except
as such enforceability may be limited by (a) bankruptcy, insolvency, reorganization, moratorium or similar laws of general applicability affecting the enforcement of creditors’ rights and (b) the application of general principles of
equity (regardless of whether such enforceability is considered in a proceeding in equity or at law). Each of this Amendment and the Amendment No. 2 Fee Letter (x) does not require any consent or approval of, registration or filing with,
or any other action by, any Governmental Authority or any third party, except for such as have been obtained or made and are in full force and effect, (y) will not violate any applicable law or regulation or the charter, bylaws or other

(z) will not violate or result in an event of default under any material indenture, agreement or other instrument binding upon such Obligor and its Subsidiaries or assets, or give rise to a right thereunder to require any payment to be made by
any such Person. 
 (ii) No Default has occurred or is continuing or will result after giving effect to this Amendment. 

(iii) The representations and warranties made by or with respect to such Obligor in Section 7 of the Loan Agreement are true in

all material respects on such earlier date. 
 (iv) There has been no Material Adverse Effect since the date of the Loan Agreement. 

(b) Each Obligor hereby ratifies, confirms, reaffirms, and acknowledges its obligations under the Loan Documents to which it is a party and
agrees that the Loan Documents remain in full force and effect, undiminished by this Amendment, except as expressly provided herein. By executing this Amendment, each Obligor acknowledges that it has read, consulted with its attorneys regarding, and
understands, this Amendment. 
  

	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

 5 








 (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.
