 4 








 
by the Exiting Lender of all of its respective Commitment and Revolving Credit Exposure as provided herein. Any assignments by the Lenders, including the Exiting Lender, necessary to effect the
reallocation of the Commitments and Revolving Credit Exposures are hereby consummated pursuant to the terms and provisions of this Section 2.6 of this Sixth Amendment; including, without limitation, payment to the Exiting Lender of any and all
amounts due and owing to the Exiting Lender with respect to any outstanding Revolving Credit Exposures, any interest thereon, and fees or other amounts payable hereunder on the Sixth Amendment Effective Date. On the Sixth Amendment Effective Date
and after giving effect to such reallocation, the Maximum Credit Amount of each Lender shall be as set forth on Annex I to this Sixth Amendment. Each Lender hereby consents and agrees to the Maximum Credit Amounts as set forth on Annex I of this
Sixth Amendment. The Exiting Lender has executed this Sixth Amendment solely for purposes of this Section 2.6. 
 Annex I to the Credit
Agreement is hereby replaced with Annex I to this Sixth Amendment. 
 Section 3.        Borrowing
Base.  From and after the Sixth Amendment Effective Date, the Borrowing Base shall be, and hereby is, equal to the amount of $2,800,000,000, which Borrowing Base shall remain in effect until the next Scheduled Redetermination or the
Borrowing Base is otherwise redetermined or adjusted in accordance with the Credit Agreement. Notwithstanding the foregoing, the Borrowing Base may be subject to further adjustments from time to time pursuant to Section 2.07(e),
Section 8.12(c) or Section 9.11. Each of the Parent Guarantor and the Borrower, on the one hand, and the Administrative Agent and the Lenders, on the other hand, agree that the redetermination of the Borrowing Base pursuant to this
Section 3 shall constitute a Scheduled Redetermination. This Section 3 constitutes notice of the redetermined Borrowing Base in accordance with Section 2.07(d) of the Credit Agreement. 

Section 4.        Conditions Precedent.  This Sixth Amendment shall not become effective until
the date on which each of the following conditions is satisfied (or waived in accordance with Section 12.02 of the Credit Agreement): 

4.1      The Administrative Agent shall have received from the Borrower, the Parent Guarantor and each Lender,
counterparts of this Sixth Amendment signed on behalf of such Person. 
 4.2      The Administrative Agent,

4.3      No Default or Event of Default shall have occurred and be continuing as of the date hereof, after
giving effect to the terms of this Sixth Amendment. 
 The Administrative Agent is hereby authorized and directed to declare this Sixth
Amendment to be effective when it has received documents confirming or certifying, to the 

  
 5 








 
satisfaction of the Administrative Agent, compliance with the conditions set forth in this Section 4 or the waiver of such conditions as permitted hereby. Such declaration shall be final,
conclusive and binding upon all parties to the Credit Agreement for all purposes. 

Section 5.        Miscellaneous. 

5.1      Confirmation.  The provisions of the Credit Agreement, as amended by this Sixth
Amendment, shall remain in full force and effect following the effectiveness of this Sixth Amendment.

the Lenders that, within thirty (30) days of the Sixth Amendment Effective Date, the Parent Guarantor and the Borrower will, and will cause their Restricted Subsidiaries to, execute and deliver amendments or supplements to the existing
mortgages in form and substance reasonably satisfactory to the Administrative Agent sufficient to (i) evidence the amendments to the Credit Agreement contemplated by this Sixth Amendment and (ii) create first priority, perfected Liens
(provided that Liens which are permitted by the terms of Section 9.03 of the Credit Agreement to attach to the Mortgaged Properties may exist and have whatever priority such Liens have at such time under applicable law) on at least 80% of the
total value of the Oil and Gas Properties evaluated in the Reserve Report used to determine the Borrowing Base in connection with this Sixth Amendment. 

5.3      Ratification and Affirmation; Representations and Warranties.  Each Obligor hereby
(a) acknowledges the terms of this Sixth Amendment; (b) ratifies and affirms its obligations under, and acknowledges, renews and extends its continued liability under, each Loan Document to which it is a party and agrees that each Loan

shall continue to secure the payment of all the Indebtedness of the Credit Parties under the Loan Documents, in each case, as amended by this Amendment; and (d) represents and warrants to the Lenders that as of the date hereof, after giving
effect to the terms of this Sixth Amendment: (i) all of the representations and warranties contained in each Loan Document to which it is a party are true and correct, except to the extent any such representations and warranties are expressly
limited to an earlier date, in which case, such representations and warranties shall continue to be true and correct as of such specified earlier date and (ii) no Default or Event of Default has occurred and is continuing. 

5.4      No Waiver; Loan Document.  The execution, delivery and effectiveness of this Sixth
Amendment shall not, except as expressly provided herein, operate as a waiver of any right, power or remedy of any Lender or the Administrative Agent under any of the Loan Documents, nor constitute a waiver of any provision of any of the Loan
Documents. On and after the Sixth Amendment Effective Date, this Sixth Amendment shall for all purposes constitute a Loan Document.

 6 








 5.6        NO ORAL AGREEMENT.  THIS
SIXTH AMENDMENT, THE CREDIT AGREEMENT AND THE OTHER LOAN DOCUMENTS EXECUTED IN CONNECTION HEREWITH AND THEREWITH REPRESENT THE FINAL AGREEMENT BETWEEN THE PARTIES AND MAY NOT BE CONTRADICTED BY EVIDENCE OF PRIOR, CONTEMPORANEOUS, OR UNWRITTEN ORAL
AGREEMENTS OF THE PARTIES. AS OF THE DATE OF THIS SIXTH AMENDMENT, THERE ARE NO ORAL AGREEMENTS BETWEEN THE PARTIES. 

5.7        GOVERNING LAW.  THIS SIXTH AMENDMENT (INCLUDING, BUT NOT LIMITED TO, THE
VALIDITY AND ENFORCEABILITY HEREOF) SHALL BE GOVERNED BY, AND CONSTRUED IN ACCORDANCE WITH, THE INTERNAL LAWS OF THE STATE OF NEW YORK. 

5.8        Severability.  Any provision of this Sixth Amendment which is prohibited
or unenforceable in any jurisdiction shall, as to such jurisdiction, be ineffective to the extent of such prohibition or unenforceability without invalidating the remaining provisions hereof, and any such prohibition or unenforceability in any
jurisdiction shall not invalidate or render unenforceable such provision in any other jurisdiction.
