 NOW, THEREFORE, in consideration of the premises and agreements, provisions and covenants herein contained, the parties hereto agree as follows: 

Each New Loan Lender party hereto hereby agrees to commit to provide its respective New Revolving Credit Commitment on the Restatement

Agreement, once delivered, are irrevocable and may not be withdrawn. 
 Upon satisfaction of the above “Condition to Effectiveness” on
the Effective Date, this Agreement shall be a binding agreement between the parties hereto. Upon the Effective Date, for purposes of the Commitment Letter dated as of October 16, 2011 (the “Commitment Letter”) by and among
Kinder Morgan, Inc. and Barclays Bank PLC, the Borrower shall be deemed to have received the New Revolving Credit Commitments hereunder in an aggregate principal amount of $750,000,000, and the commitments of the Commitment Party (as defined in the
Commitment Letter) under the Revolving Facility (as defined in the Commitment Letter) shall be reduced on a dollar for dollar basis as set forth in clause (a) of the section entitled “Mandatory Reduction of Commitments” in
Exhibit C-3 of the Commitment Letter. 
 2. Condition to Availability. Notwithstanding anything to the contrary
set forth herein or in the Credit Agreement, the Increased Amount Date with respect to the New Revolving Credit Commitments hereunder shall not occur, no assignments by the New Loan Lenders of any New Revolving Credit Commitments hereunder shall be
permitted and no Borrowings under the New Revolving Credit Commitments hereunder shall be available to the Borrower, until the following conditions are satisfied: 
  

	 	a.	The occurrence of the Restatement Effective Date and effectiveness of the Credit Agreement in accordance with the terms of Amendment No. 2; and


  

	 	b.	The Borrower shall deliver or cause to be delivered, to the Successor Administrative Agent, the Collateral Agent, the Global Coordinator, and the New Loan Lenders party
hereto, any legal opinions referenced in Section 3(b) below. 

 3. Borrower Covenants. By its
execution of this Agreement, the Borrower hereby covenants that: 
  

	 	a.	The Borrower shall make any payments required pursuant to Section 2.11 of the Credit Agreement in connection with the New Revolving Credit Commitments;


  

	 	b.	The Borrower shall deliver or cause to be delivered the legal opinions of (i) Simpson Thacher & Bartlett LLP, counsel to the Borrower in substantially in
the form of Exhibit I-1 of Amendment No. 2 (with such changes directly related to any changes in fact, law, rule or regulation that are the subject of such opinions between the Amendment No. 2 Effective Date and the Restatement
Effective Date as may be made in Simpson Thacher & Bartlett LLP’s reasonable discretion as well as any changes requested by Simpson Thacher & Bartlett LLP’s opinion committee during such time and agreed to by the Global
Coordinator in its reasonable discretion) and (ii) each local counsel to the Borrower in the jurisdictions listed in Schedule I of Amendment No. 2 in substantially the forms attached as Exhibits I-2 and I-3 to
Amendment No. 2 (with such changes directly related to any changes in fact, law, rule or regulation that are the subject of such opinions between the Amendment No. 2 Effective Date and the Restatement Effective Date as may be made in each
such local counsel’s reasonable discretion as well as any changes requested by each such local counsel during such time and agreed to by the Global Coordinator in its reasonable discretion). The Borrower and the other Credit Parties hereby
instruct such counsel to deliver such legal opinions; and 


  
 - 2 -











	 	c.	The Borrower shall pay to each New Loan Lender the Ticking Fee (as defined below) earned from the Effective Date and through the earlier of the Restatement Effective
Date or the Outside Date (as defined below), which Ticking Fee, to the extent earned, shall be payable on the earlier of the (i) Restatement Effective Date and (ii) the Outside Date. 


“Ticking Fee” means a non-refundable ticking fee calculated at the Applicable Ticking Fee Rate (as defined below) on
each New Loan Lender’s New Revolving Credit Commitments. “Applicable Ticking Fee Rate” means the rate per annum set forth below in Column B below opposite the applicable “Debt Ratings of the Borrower” from
Moody’s and S&P in Column A below, in each case, with a stable or better outlook: 
  

							
	 Level
	  	 Column A

(Debt Ratings of the Borrower)
	  	Column B
(Applicable
Ticking
Fee
Rate)	 
	 Level 1
	  	BBB-/Baa3 or higher	  	 	0.25	% 
	 Level 2
	  	BB+/Ba1	  	 	0.30	% 
	 Level 3
	  	BB/Ba2	  	 	0.375	% 
	 Level 4
	  	BB-/Ba3 or lower	  	 	0.50	% 

 In the event of a split rating, the Applicable Ticking Fee Rate will be determined by reference to the
“Level” in the grid above in which the higher rating appears, unless the split in the Debt Ratings is two or more Levels apart, in which case the Applicable Ticking Fee Rate will be determined by reference to the Level in the grid that is
one higher than the Level in which the lower rating appears. The Debt Ratings shall be determined from the most recent public announcement of any changes in the Debt Ratings. Prior to the public announcement of Debt Ratings for the Borrower that
give effect to the Transactions, the Applicable Ticking Fee Rate will be determined by reference to Level 2 in the grid above. 
  

	 	d.	The Borrower shall pay to each New Loan Lender a non-refundable upfront fee (the “Upfront Fees”) equal to 0.25% of each New Loan Lender’s New
Revolving Credit Commitments to be earned upon this date hereof and payable on the earlier of (i) the Restatement Effective Date and (ii) the Outside Date (as defined below). 


 

	 	e.	 For the avoidance of doubt, any Ticking Fees or Upfront Fees paid or payable by the Borrower to any New Loan Lender under this Agreement shall not be
duplicative of (i) any ticking fees actually paid to Barclays Capital pursuant to Exhibit C of the Commitment Letter dated as of October 16, 2011, to the extent earned with respect to the period after the Effective Date, (ii) any
“Revolving Facility Upfront Fee” (as defined in the Fee Letter) actually paid to Barclays Capital pursuant to the Fee Letter (the “Fee Letter”), dated as of October 16, 2011, between Barclays Capital and the Successor
Borrower and (iii) any “Revolving Facility

Upfront Fee” (as defined in the Joinder) actually paid to the Additional Commitment Parties (as defined in the Joinder) pursuant to the terms of the Joinder Agreement (the
“Joinder”), dated as of October 31, 2011 among the Successor Borrower, Barclays Capital and the other Additional Commitment Parties party thereto, in each case on account of the New Revolving Credit Commitments. 

4. Successor Administrative Agent Covenant. Upon the Restatement Effective Date, the Successor Administrative Agent will record
this Agreement in the Register. 
 5. New Loan Lender Covenant. Upon the Restatement Effective Date, each New Loan Lender
covenants and/or confirms that: 
  

	 	a.	Such New Loan Lender shall be subject to the requirements set forth in Sections 5.4(d) and (e) of the Credit Agreement and shall deliver to the
Successor Administrative Agent an Administrative Questionnaire as required by Section 14.6(b)(ii)(D) of the Credit Agreement; 

  

	 	b.	If such New Loan Lender is not a Lender under the Existing Credit Agreement, such New Loan Lender shall become a “Lender” under, and for all purposes of, the
Credit Agreement and the other Credit Documents, and shall be subject to and bound by the terms thereof, and shall perform all the obligations of and shall have all rights of a Lender thereunder; and 


 

	 	c.	If such New Loan Lender is not a Lender under the Existing Credit Agreement, such New Loan Lender has delivered to the Successor Administrative Agent such forms,
certificates or other documents with respect to United States federal income tax withholding matters as such New Loan Lender is required to deliver to the Successor Administrative Agent pursuant to Section 5.4(d), Section 5.4(e),
and/or Section 5.4(h) of the Credit Agreement. 

 6. Credit Agreement Governs. Except as set
forth in this Agreement, the New Revolving Loans shall otherwise be subject to the provisions of the Credit Agreement and the other Credit Documents. 
 7. Notice. For purposes of the Credit Agreement, the initial notice address of each New Loan Lender that is not a Lender under the Existing Credit Agreement shall be as set forth below its
signature below. 
 8. Amendment, Modification and Waiver. This Agreement may not be amended, modified or waived except
by an instrument or instruments in writing signed and delivered on behalf of each of the parties hereto. 
 9. Entire
Agreement. This Agreement, the Credit Agreement and the other Credit Documents constitute the entire agreement among the parties with respect to the subject matter hereof and thereof and supersede all other prior agreements and understandings,
both written and verbal, among the parties or any of them with respect to the subject matter hereof. 
 10. GOVERNING
LAW. THIS AGREEMENT AND THE RIGHTS AND OBLIGATIONS OF THE PARTIES HEREUNDER SHALL BE GOVERNED BY, AND CONSTRUED AND INTERPRETED IN ACCORDANCE WITH, THE LAW OF THE STATE OF NEW YORK.

 11. Severability. Any term or provision of this Agreement which is invalid or
unenforceable in any jurisdiction shall, as to that jurisdiction, be ineffective to the extent of such invalidity or unenforceability without rendering invalid or unenforceable the remaining terms and provisions of this Agreement or affecting the
validity or enforceability of any of the terms or provisions of this Agreement in any other jurisdiction. If any provision of this Agreement is so broad as to be unenforceable, the provision shall be interpreted to be only so broad as would be
enforceable. 
 12. Counterparts. This Agreement may be executed in counterparts, each of which shall be deemed to be an
original, but all of which shall constitute one and the same agreement. 
 13. Outside Date. Notwithstanding anything
herein to the contrary, if the Outside Date (as defined below) occurs prior to the Restatement Effective Date and the availability of the New Revolving Credit Commitments pursuant to Section 2 hereunder, the New Revolving Credit
Commitments hereunder shall automatically terminate. “Outside Date” shall mean the earlier of (i) 11:59 p.m. (New York time) on June 30, 2012 (the “Initial Outside Date”) or, if the conditions set forth in
the following sentence have been satisfied, 11:59 p.m. (New York time) on December 31, 2012 (the “Extended Outside Date”) and (ii) the date of termination of all New Revolving Credit Commitments hereunder prior to the
Restatement Effective Date by delivery of an irrevocable written notice by the Borrower to each of the New Loan Lenders of the termination of all such New Revolving Credit Commitments (whereupon such New Revolving Credit Commitments shall be
terminated). The Borrower may extend the Initial Outside Date to the Extended Outside Date so long as (x) the “Walk-Away Date” (as defined in the Acquisition Agreement) has been extended to the “Extended Walk-Away Date” (as
defined in the Acquisition Agreement) pursuant to Section 7.1(b)(i) of the Acquisition Agreement (as in effect on the Amendment No. 2 Effective Date (with such changes as are not materially adverse to any material interest of the
Lenders)), (y) the Borrower shall have delivered to the Successor Administrative Agent a copy of the written extension notice required under such Section 7.1(b)(i) of the Acquisition Agreement promptly upon delivery of the same under the
Acquisition Agreement and in any case on or prior to the Initial Outside Date and (z) the Borrower shall pay to the Global Coordinator an extension fee for the ratable benefit and account of the New Loan Lenders in an amount equal to 0.25% of
the New Revolving Credit Commitments of the New Loan Lenders on or prior to the earlier to occur of (i) the Restatement Effective Date and (ii) the Outside Date.
