 This First Amendment to Second Amended and Restated 5-Year Revolving

 Recitals 
 A. The Borrower, the Administrative Agent and the other agents and
Lenders party thereto are parties to that certain Second Amended and Restated 5-Year Revolving Credit Agreement dated as of March 31, 2011 (the “Agreement”, as amended, modified, supplemented restated or replaced from time to
time) pursuant to which the Lenders have made certain credit available to and on behalf of the Borrower. 
 B. The Borrower has
requested and the Administrative Agent and the Lenders agree that certain terms and provisions of the Agreement be amended as provided in this First Amendment. 
 C. NOW, THEREFORE, in consideration of the premises and the mutual covenants herein contained, for good and valuable consideration, the receipt and sufficiency of which are hereby acknowledged, the
parties hereto agree as follows: 
 Section 1. Defined Terms. Each capitalized term which is defined in the
Agreement, but which is not defined in this First Amendment, shall have the meaning ascribed such term in the Agreement. Unless otherwise indicated, all section references in this First Amendment refer to the Agreement. 

Section 2. Amendments to Agreement. 
 2.1 Section 1.01. Section 1.01 is hereby amended by deleting the following definitions and replacing them with the following: 

““Agreement” means this Second Amended and Restated 5-Year Revolving Credit Agreement, as the same
has been amended by that certain First Amendment dated as of December 20, 2012 and as the same may be further amended, modified, supplemented restated or replaced from time to time.” 

““Applicable Margin” means, for any day, with respect to any ABR Loan or any Eurodollar Loan, or
with respect to the commitment fees payable hereunder, as the case may be, the Applicable Margin per annum set forth below under the caption “ABR Spread”, “Eurodollar Spread” or “Commitment Fee Rate”, as the case may
be, based upon the ratings by Moody’s and S&P, respectively, applicable on such date to the Index Debt: 

													
	 Index Debt Ratings
	  	Commitment Fee Rate	 	 	Eurodollar Spread	 	 	ABR Spread	 
	 Category 1

>Baa1/BBB+
	  	 	0.150	% 	 	 	1.125	% 	 	 	0.125	% 
	 Category 2

Baa2/BBB
	  	 	0.200	% 	 	 	1.250	% 	 	 	0.250	% 
	 Category 3

Baa3/BBB-
	  	 	0.250	% 	 	 	1.500	% 	 	 	0.500	% 
	 Category 4

Ba1/BB+
	  	 	0.300	% 	 	 	1.750	% 	 	 	0.750	% 
	 Category 5

<Ba2/BB
	  	 	0.350	% 	 	 	2.000	% 	 	 	1.000	% 

 For purposes of the foregoing, if both Moody’s and S&P shall not have in effect
a rating for the Index Debt (other than by reason of the circumstances referred to in the last sentence of this definition), then such agencies shall be deemed to have established a rating in Category 5. If the ratings established or deemed to have
been established by Moody’s and S&P for the Index Debt shall fall within different Categories, the Applicable Margin shall be based on the higher of the two ratings, unless one of the two ratings is two or more Categories lower than the
other, in which case the Applicable Margin shall be determined by reference to the Category next above that of the lower of the two ratings; provided, however, that if only one of Moody’s and S&P shall have established a rating, then the
Applicable Margin shall be determined by reference to such available rating. If the ratings established or deemed to have been established by Moody’s and S&P for the Index Debt shall be changed (other than as a result of a change in the
rating system of Moody’s and S&P), such change shall be effective as of the date on which it is first announced by the applicable rating agency, irrespective of when notice of such change shall have been furnished by the Borrower to the
Agent and the Lenders pursuant to Section 5.01 or otherwise. Each change in the Applicable Margin shall apply during the period commencing on the effective date of such change and ending on the date immediately preceding the effective date of
the next such change. If the rating system of Moody’s or S&P shall change, or if either such rating agency shall cease to be in the business of rating corporate debt obligations, the Borrower and the Lenders shall negotiate in good faith to
amend this definition to reflect such changed rating system or the unavailability of ratings from such rating agency and, pending the effectiveness of any such amendment, the Applicable Margin shall be determined by reference to the rating of such
agency most recently in effect prior to such change or cessation.” 
 “Commitment” means,
with respect to each Lender, the commitment of such Lender to make Revolving Loans and to acquire participations in Letters of Credit and Swingline Loans hereunder, expressed as an amount representing the maximum aggregate amount of such
Lender’s Credit Exposure hereunder, as such commitment may be (a) increased from time to time pursuant to Section 2.02, (b) reduced from time to time pursuant to Section 2.09, or (c) reduced or increased from time to
time pursuant to assignments by or to such Lender pursuant to Section 9.04. The initial amount of each Lender’s Commitment is set forth on Schedule 2.01, or in the Assignment and Assumption pursuant to which such Lender shall have assumed
its Commitment, as applicable. The aggregate amount of the Lenders’ Commitments is $1,500,000,000.” 

  
 2 

 ““Maturity Date” means the later of
(a) December 20, 2017 and (b) if maturity is extended pursuant to Section 2.20, such extended maturity date as determined pursuant to Section 2.20 (it being understood and agreed that any such maturity shall not be deemed
extended for any Lender that has not consented to such extension).” 
 2.2 Section 1.01. Section 1.01 is
hereby amended by adding the following definitions in the appropriate alphabetical order: 
 ““First
Amendment” means the First Amendment to Agreement dated as of December 20, 2012 among the Borrower, the Administrative Agent and the other agents and Lenders party thereto.” 

““First Amendment Effective Date” means the date on which all conditions precedent to the First
Amendment are satisfied.” 
 2.3 Section 2.21(c). Section 2.21(c) to the Agreement is hereby amended by
deleting it in its entirety and replacing it with the following: 
 “(c) Reallocation of Applicable
Percentages to Reduce Fronting Exposure. During any period in which there is a Defaulting Lender, for purposes of computing the amount of the obligation of each non-Defaulting Lender to acquire, refinance or fund participations in Letters of
Credit or Swingline Loans pursuant to Section 2.05 and Section 2.06, the Applicable Percentage of each non-Defaulting Lender shall be computed without giving effect to the Commitment of such Defaulting Lender; provided that
(i) each such reallocation shall be given effect only if, at the date the applicable Lender becomes a Defaulting Lender, no Default or Event of Default exists, (ii) the aggregate obligation of each non-Defaulting Lender to acquire,
refinance or fund participations in Letters of Credit and Swingline Loans shall not exceed the positive difference, if any, of (A) the Commitment of that non-Defaulting Lender minus (B) the aggregate outstanding principal amount of the
Revolving Loans of that Lender and (iii) the conditions set forth in Section 4.02 shall have been satisfied.” 

2.4 Article III. Article III to the Agreement is hereby amended by adding the following as Section 3.12: 

“Section 3.12 Margin Stock. Neither the Borrower nor any of its Subsidiaries is engaged principally, or as one
of its or their important activities, in the business of extending credit for the purpose, whether immediate, incidental or ultimate, of buying or carrying margin stock (within the meaning of Regulation T, U or X of the Board).” 

2.5 Section 9.04(b)(2). Section 9.04(b)(2) is hereby amended by adding the following as Section 9.04(b)(2)(E):

 “(E) the assignee shall not be a natural person.” 

2.6 Article IX. Article IX to the Agreement is hereby amended by adding the following as Section 9.15: 

“Section 9.15 No Fiduciary Duty. Each Lender and its Affiliates (collectively, solely for purposes of this
paragraph, the “Lenders”), may have economic interests that conflict with those of the Borrower. The Borrower agrees that nothing in the Loan Documents will be deemed to create an advisory, fiduciary or agency relationship or
fiduciary or other implied duty between any Lender, on the one hand, and the Borrower, 

  
 3 

 
on the other. The Borrower acknowledges and agree that (i) the transactions contemplated by the Loan Documents (including the exercise of rights and remedies hereunder and thereunder) are
arm’s-length commercial transactions between the Lenders, on the one hand, and the Borrower, on the other, and (ii) in connection therewith and with the process leading thereto, (x) no Lender has assumed an advisory or fiduciary
responsibility in favor of the Borrower with respect to the transactions contemplated hereby (or the exercise of rights or remedies with respect thereto) or the process leading thereto (irrespective of whether any Lender has advised, is currently
advising or will advise the Borrower on other matters) and (y) each Lender is acting solely as principal and not as the agent or fiduciary of the Borrower. The Borrower acknowledges and agrees that it has consulted its own legal and financial
advisors to the extent it deemed appropriate and that it is responsible for making its own independent judgment with respect to the transactions contemplated hereby and the process leading thereto.” 

2.7 Amendment to Schedule 2.01. Schedule 2.01 to the Agreement is hereby amended by deleting it in its entirety and replacing it
with Schedule 2.01 attached hereto. 
 2.8 Investment Grade Date Provisions. Certain provisions of the Agreement are no
longer applicable or were permanently deleted as a result of the occurrence of an Investment Grade Date. Accordingly, the parties hereby agree as follows: 
 (a) The definitions of “Hydrocarbon Interests”, “Investment Grade Date”, “MLP Units”, “Oil and Gas Properties”, “Proved Reserves”, “PV”,
“Reserve Information” and “Reserve Report” are hereby deleted. 
 (b) Paragraph (c) of
Section 4.02 is deleted, and the last two sentences of Section 4.02 are amended to read as follows: 

“Each Borrowing and each issuance, amendment, renewal or extension of a Letter of Credit shall be deemed to
constitute a representation and warranty by the Borrower on the date thereof as to the matters specified in paragraphs (a) and (b) of this Section.” 

(c) Paragraph (c) of Section 5.01 is amended to read as follows: 

“(c) concurrently with any delivery of financial statements under subsections (a) or (b) of this
Section 5.01, a certificate of a Financial Officer of the Borrower (i) certifying as to whether a Default has occurred and, if a Default has occurred, specifying the details thereof and any action taken or proposed to be taken with respect
thereto, and (ii) setting forth reasonably detailed calculations demonstrating compliance with Sections 6.04 (a);” 
 (d) Paragraph (e) of Section 5.01 is deleted and replaced with “(e) [Intentionally Omitted]”. 
 (e) Paragraph (b) of Section 6.04 is deleted and replaced with “(b) [Intentionally Omitted]”. 
 Section 3. Conditions Precedent. The effectiveness of this First Amendment is subject to the receipt by the Administrative Agent of the following documents and satisfaction of the other
conditions provided in this Section 3, each of which shall be reasonably satisfactory to the Administrative Agent in form and substance (the date on which such effectiveness occurs, the “ First Amendment Effective Date”):

  
 4 

 3.1 The Administrative Agent (or its counsel) shall have received from each party hereto

Borrower hereunder. 
 3.3 The Administrative Agent shall have received a certificate of the Secretary or an Assistant Secretary

(3) specimen signatures of such authorized officers, and (4) the organizational documents of such Obligor, certified as being true and complete. The Administrative Agent and the Lenders may conclusively rely on such certificate until the

received duly executed promissory notes payable to each Lender that has requested a promissory note in a principal amount equal to its Commitment dated as of the First Amendment Effective Date.

 5 

 5.2 Except as specifically amended hereby, the Agreement and each other Loan Document shall
remain in full force and effect and are hereby ratified and confirmed. 
 5.3 This First Amendment is limited as specified
herein and shall not constitute an amendment or waiver of, or an indication of the Administrative Agent’s or the Lenders’ willingness to amend or waive, any other provisions of the Agreement or the other Loan Documents for any other date
or purpose.

6.1 For an agreed consideration, each Lender (individually an “Assignor” and collectively, the
“Assignors”) hereby irrevocably sells and assigns, severally and not jointly, (i) all of such Assignor’s rights and obligations in its capacity as Lender under the Agreement and any other documents or instruments delivered
pursuant thereto to the extent related to its Commitment and Credit Exposure, as the case may be, identified in Annex I attached hereto and (ii) to the extent permitted to be assigned under applicable law, all claims, suits, causes of action
and any other right of such Assignor (in its capacity as Lender) against any Person, whether known or unknown, arising under or in connection with the Agreement, any other documents or instruments delivered pursuant thereto or the transactions
governed thereby or in any way based on or related to any of the foregoing, including contract claims, tort claims, malpractice claims, statutory claims and all other claims at law or in equity related to the rights and obligations sold and assigned
pursuant to clause (i) above (the rights and obligations sold and assigned pursuant to clauses (i) and (ii) above being referred to herein collectively for all Assignors as the “Assigned Interests”) to the Lenders
(individually, an “Assignee” and, collectively, the “Assignees”) set forth on Schedule 2.01 to this First Amendment (which shall replace the existing Schedule 2.01 to the Agreement as of the First Amendment
Effective Date), and each Assignee hereby irrevocably purchases and assumes from each Assignor such Assignee’s percentage (as set forth on Schedule 2.01 to this First Amendment) of the Assigned Interests, subject to and in accordance with the
Agreement and this First Amendment, as of the First Amendment Effective Date. Such sale and assignment is without recourse to the Assignors and, except as expressly provided in this First Amendment, without representation or warranty by the
Assignors. 
 6.2 From and after the First Amendment Effective Date, the Administrative Agent shall distribute all payments in
respect of the Assigned Interests (including payments of principal, interest, fees and other amounts) to the appropriate Assignors for amounts which have accrued to but excluding the First Amendment Effective Date and to the appropriate Assignees
for amounts which have accrued from and after the First Amendment Effective Date. 
 6.3 After giving effect to the assignments
in Section 6.1 of this First Amendment, Comerica Bank (the “Exiting Lender”) shall cease to be a party to the Agreement as of the First Amendment Effective Date and shall no longer be a “Lender”. The Exiting Lender
