(as heretofore amended, modified or supplemented, the “Existing Credit Agreement”). 
  
 B. The Borrower has requested the Lenders, and the Lenders have agreed, to amend and restate the Existing Credit Agreement subject to the terms and
conditions of this Agreement. 
  
 C. Now, therefore, in
consideration of the mutual covenants and agreements herein contained and of the loans, extensions of credit and commitments hereinafter referred to, the parties hereto agree as follows: 
  
 ARTICLE I 
 DEFINITIONS 
  
 Section 1.01 Defined
Terms. As used in this Agreement, the following terms have the meanings specified below: 
  
 “ABR”, when used in reference to any Loan or Borrowing, refers to whether such Loan, or the Loans comprising such Borrowing, are bearing
interest at a rate determined by reference to the Alternate Base Rate. 
  
 “Adjusted LIBO Rate” means, with respect to any Eurodollar Borrowing for any Interest Period, an interest rate per annum (rounded upwards, if necessary, to the next 1/16 of 1%) equal to (a) the LIBO Rate for such Interest
Period multiplied by (b) the Statutory Reserve Rate. 
  
 “Administrative Agent” means JPMorgan Chase Bank, N.A. (as successor by merger to JPMorgan Chase Bank), in its capacity as administrative agent for the Lenders hereunder. 
  
 “Administrative Questionnaire” means an Administrative
Questionnaire in a form supplied by the Administrative Agent. 
  
 “Affected Loans” has the meaning set forth in Section 2.20. 
  
 “Affiliate” means, with respect to a specified Person, another Person that directly, or indirectly through one or more intermediaries, Controls or is Controlled by or is under common Control with the
Person specified. A Person shall not be considered to be an “Affiliate” of an 

  

 1 

 
Oil and Gas Royalty Trust/MLP solely by virtue of its ownership of Equity Interests of such Oil and Gas Royalty Trust/MLP. 
  
 “Agent” means the Administrative Agent, any Co-Syndication
Agent or Co-Documentation Agent or all of the foregoing, as the context requires. 
  
 “Agreement” means this Amended and Restated 5-Year Revolving Credit Agreement, as the same may be amended, modified, restated, or replaced from time to time. 
  
 “Alternate Base Rate” means, for any day, a rate per annum
equal to the greater of (a) the Prime Rate in effect on such day and (b) the Federal Funds Effective Rate in effect on such day plus 1/2 of 1%. Any change in the Alternate Base Rate due to a change in the Prime Rate or the Federal Funds Effective
Rate shall be effective from and including the effective date of such change in the Prime Rate or the Federal Funds Effective Rate, respectively. 
  
 “Applicable Margin” means, for any day, with respect to 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 “Commitment Fee Rate” or “Eurodollar Spread”, as the case may be, based upon the rating by S&P and Moody’s, respectively, applicable on
such date to the Index Debt: 
  

							
	 Index Debt Ratings

	  	Commitment Fee Rate

	 	 	Eurodollar Spread

	 
	 Category 1
 3Baa1/BBB+
	  	0.090	%	 	0.375	%
			
	 Category 2
 Baa2/BBB
	  	0.110	%	 	0.500	%
			
	 Category 3
 Baa3/BBB-
	  	0.125	%	 	0.625	%
			
	 Category 4
 < Baa3/BBB-
	  	0.175	%	 	0.875	%

  
 provided that for each day during
which the Borrower’s utilization of available aggregate Commitments is greater than or equal to 50%, the then applicable Eurodollar Spread will be increased by 0.125 %. 
  
 Applicable Margin for ABR Loans is zero percent (0%). 
  
 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 4. 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 or S&P shall 

  

 2 

 
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 or 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(f) 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. 
  
 “Applicable Percentage” means, with respect to any Lender,
the percentage of the Commitments represented by such Lender’s Commitment. If the Commitments have increased, terminated or expired, the Applicable Percentages shall be determined based upon the Commitments most recently in effect, giving
effect to any assignments. 
  
 “Approved Fund”
has the meaning assigned to such term in Section 9.04. 
  
 “Assignment and Assumption” means an assignment and assumption entered into by a Lender and an assignee (with the consent of any party whose consent is required by Section 9.04), and accepted by the Administrative Agent, in
the form of Exhibit A or any other form approved by the Administrative Agent. 
  
 “Availability Period” means the period from and including the Effective Date to but excluding the earlier of the Maturity Date and the date of termination of the Commitments. 
  
 “Board” means the Board of Governors of the Federal Reserve
System of the United States of America.

Borrowing in accordance with Section 2.04. 
  
 “Business
Day” means any day that is not a Saturday, Sunday or other day on which commercial banks in New York City or Texas are authorized or required by law to remain closed; provided that, when used in connection with a Eurodollar Loan, the term
“Business Day” shall also exclude any day on which banks are not open for dealings in dollar deposits in the London interbank market. 
  

 3 

 “Capital Lease Obligations” of any Person means the obligations of such Person to pay
rent or other amounts under any lease of (or other arrangement conveying the right to use) real or personal property, or a combination thereof, which obligations are required to be classified and accounted for as capital leases on a balance sheet of

 “Cash Equivalents” means: (a) securities with maturities of one year or less from the date of acquisition issued or fully guaranteed or
insured by the United States government or any agency thereof, (b) certificates of deposit and eurodollar time deposits with maturities of one year or less from the date of acquisition and overnight bank deposits of any Lender or of any commercial

Restricted Subsidiary that is organized in a foreign jurisdiction and is required by the applicable laws and regulations of such foreign jurisdiction to be partially owned by the government of such foreign jurisdiction or individual or corporate
citizens of such foreign jurisdiction, provided that the Borrower, directly or indirectly, owns the remaining Equity Interests in such Subsidiary and, by contract or otherwise, controls the management and business of such Subsidiary and derives
economic benefits of ownership of such Subsidiary to substantially the same extent as if such Subsidiary were a Wholly-Owned Subsidiary.

 ARTICLE II 
 THE CREDITS 
  
 Section 2.01 Commitments. Subject to the terms and conditions set forth herein, each Lender agrees to make
Loans in dollars to the Borrower from time to time during the Availability Period in an aggregate principal amount that will not result in (i) such Lender’s Credit Exposure exceeding such Lender’s Commitment or (ii) the sum of the total
Credit Exposures exceeding the total Commitments. Within the foregoing limits and subject to the terms and conditions set forth herein, the Borrower may borrow, prepay and reborrow Loans. 
  
 Section 2.02 Commitment Increase. 
  
 (a) Subject to the terms and conditions set forth herein, the Borrower shall have the right, without the
consent of the Lenders but with the prior approval of the Administrative Agent (not to be unreasonably withheld or delayed), to cause from time to time an increase in the Commitments of the Lenders (a “Commitment Increase”) by
adding to this Agreement one or more additional financial institutions that is not already a Lender hereunder and that is reasonably satisfactory to the Administrative Agent (each a “CI Lender”) or by 

  

 20 

 
allowing one or more existing Lenders to increase their respective Commitments; provided, however that (i) no Event of Default shall have occurred which is
continuing, (ii) no such Commitment Increase shall cause the Commitments under this Agreement to exceed $2,000,000,000, (iii) no Lender’s Commitment shall be increased without such Lender’s prior written consent (which consent may be given
or withheld in such Lender’s sole and absolute discretion) and (iv) if, on the effective date of such increase, any Loans have been funded, then the Borrower shall be obligated to pay any breakage fees or costs in connection with the
reallocation of such outstanding Loans. 
  
 (b)
Any Commitment Increase shall be requested by written notice from the Borrower to the Administrative Agent (a “Notice of Commitment Increase”) in the form of Exhibit B attached hereto and shall be approved by the Administrative
Agent, such consent to not be unreasonably withheld. Each such Notice of Commitment Increase shall specify (i) the proposed effective date of such Commitment Increase, which date shall be no earlier than five (5) Business Days after receipt by the
Administrative Agent of such Notice of Commitment Increase, (ii) the amount of the requested Commitment Increase (provided that after giving effect to such requested Commitment Increase, the aggregate amount of the Commitments does not exceed the
amount set forth in subsection (a)(ii) above), (iii) the identity of each CI Lender or Lender that has agreed in writing to increase its Commitment hereunder, and (iv) the amount of the respective Commitments of the then existing Lenders and the CI
Lenders from and after the Commitment Increase Effective Date (as defined below). The Administrative Agent shall review each Notice of Commitment Increase and shall notify the Borrower whether or not the Administrative Agent consents to the proposed
Commitment Increase. If the Administrative Agent consents to such Commitment Increase (such consent not to be unreasonably withheld), the Administrative Agent shall execute a counterpart of the Notice of Commitment Increase and such Commitment
Increase shall be effective on the proposed effective date set forth in the Notice of Commitment Increase (if the Administrative Agent consented to such Commitment Increase prior to such proposed date) or on another date agreed to by the
Administrative Agent and the Borrower (such date referred to as the “Commitment Increase Effective Date”). 
  
 (c) On each Commitment Increase Effective Date, to the extent that there are Loans outstanding as of such date, (i) each CI Lender shall,
by wire transfer of immediately available funds, deliver to the Administrative Agent such CI Lender’s New Funds Amount, which amount, for each such CI Lender, shall constitute Loans made by such CI Lender to the Borrower pursuant to this
Agreement on such Commitment Increase Effective Date, (ii) the Administrative Agent shall, by wire transfer of immediately available funds, pay to each then Reducing Percentage Lender its Reduction Amount, which amount, for each such Reducing
Percentage Lender, shall constitute a prepayment by the Borrower pursuant to Section 2.11, ratably in accordance with the respective principal amounts thereof, of the principal amounts of all then outstanding Loans of such Reducing Percentage
Lender, and (iii) the Borrower shall be responsible to pay to each Lender any breakage fees or costs in connection with the reallocation of any outstanding Loans. 
  
 (d) For purposes of this Section 2.02 and Exhibit B, the following defined terms shall have the following
meanings: (i) “New Funds Amount” means the amount equal to the product of a Lender’s increased Commitment or a CI Lender’s Commitment (as applicable) represented as a percentage of the aggregate Commitments after giving
effect to the 

  

 21 

 
Commitment Increase, times the aggregate principal amount of the outstanding Loans immediately prior to giving effect to the Commitment Increase, if any, as
of a Commitment Increase Effective Date (without regard to any increase in the aggregate principal amount of Loans as a result of borrowings made after giving effect to the Commitment Increase on such Commitment Increase Effective Date); (ii)
“Reducing Percentage Lender” means each then existing Lender immediately prior to giving effect to the Commitment Increase that does not increase its respective Commitment as a result of the Commitment Increase and whose relative
percentage of the Commitments shall be reduced after giving effect to such Commitment Increase; and (iii) “Reduction Amount” means the amount by which a Reducing Percentage Lender’s outstanding Loans decrease as of a Commitment
Increase Effective Date (without regard to the effect of any borrowings made on such Commitment Increase Effective Date after giving effect to the Commitment Increase). 
  
 (e) Each Commitment Increase shall become effective on its Commitment Increase Effective Date and upon such
effectiveness (i) the Administrative Agent shall record in the register each then CI Lender’s information as provided in the Notice of Commitment Increase and pursuant to an Administrative Questionnaire satisfactory to the Administrative Agent
that shall be executed and delivered by each CI Lender to the Administrative Agent on or before the Commitment Increase Effective Date, (ii) Schedule 2.01 hereof shall be amended and restated to set forth all Lenders (including any CI Lenders) that
will be Lenders hereunder after giving effect to such Commitment Increase (which shall be set forth in Annex I to the applicable Notice of Commitment Increase) and the Administrative Agent shall distribute to each Lender (including each CI Lender) a
copy of such amended and restated Schedule 2.01, and (iii) each CI Lender identified on the Notice of Commitment Increase for such Commitment Increase shall be a “Lender” for all purposes under this Agreement. 
  
 Section 2.03 Loans and Borrowings. 
  
 (a) Each Loan shall be made as part of a Borrowing
consisting of Loans made by the Lenders ratably in accordance with their respective Commitments. The failure of any Lender to make any Loan required to be made by it shall not relieve any other Lender of its obligations hereunder; provided that the
Commitments of the Lenders are several and no Lender shall be responsible for any other Lender’s failure to make Loans as required. 
  
 (b) Subject to Section 2.14, each Borrowing shall be comprised entirely of ABR Loans or Eurodollar Loans as the Borrower may request in
accordance herewith. Each Lender at its option (but subject to Section 2.19) may make any Eurodollar Loan by causing any domestic or foreign branch or Affiliate of such Lender to make such Loan; provided that any exercise of such option shall not
affect the obligation of the Borrower to repay such Loan in accordance with the terms of this Agreement. 
  
 (c) At the commencement of each Interest Period for any Eurodollar Borrowing, such Borrowing shall be in an aggregate amount that is an
integral multiple of $1,000,000 and not less than $1,000,000. At the time that each ABR Borrowing is made, such Borrowing shall be in an aggregate amount that is an integral multiple of $1,000,000 and not less than $1,000,000; provided that an ABR
Borrowing may be in an aggregate amount that is equal to the entire unused balance of the total Commitments or that is required to finance the 

  

 22 

 
reimbursement of an LC Disbursement as contemplated by Section 2.06(e). Borrowings of more than one Type may be outstanding at the same time; provided that
there shall not at any time be more than a total of 12 Eurodollar Borrowings outstanding. 
  
 (d) Notwithstanding any other provision of this Agreement, the Borrower shall not be entitled to request, or to elect to convert or
continue, any Borrowing if the Interest Period requested with respect thereto would end after the Maturity Date. 
  
 (e) On the Effective Date (or as soon as practicable after the Effective Date with respect to (iii)): 
  
 (i) the Borrower shall pay all accrued and unpaid commitment
fees, break funding fees under Section 2.16, if any, associated with refunded “Eurodollar Loans” outstanding under the Existing Credit Agreement and all other fees that are outstanding under the Existing Credit Agreement for the account of
each “Lender” or “Issuing Bank” under the Existing Credit Agreement; 
  
 (ii) each “ABR Loan” outstanding under the Existing Credit Agreement shall be deemed to be repaid with the proceeds of a new ABR
Loan under this Agreement; and each “Eurodollar Loan” outstanding under the Existing Credit Agreement shall be repaid with the proceeds of a new Eurodollar Loan under this Agreement made by the Lenders in accordance with their respective
Applicable Percentage of the Borrowing; 
  
 (iii)
the Administrative Agent shall use reasonable efforts to cause such “Lender” under the Existing Credit Agreement to deliver to the Borrower as soon as practicable after the Effective Date any promissory note issued by the Borrower to it
under the Existing Credit Agreement, marked “canceled” or otherwise similarly defaced; 
  
 (iv) any “Letters of Credit” issued under the Existing Credit Agreement shall be deemed issued under this Agreement (without
payment of additional fronting fees under Section 2.12(b); and 
  
 (v) the Existing Credit Agreement and the commitments thereunder shall be superceded by this Agreement and such commitments shall terminate. 
  
 (f) It is the intent of the parties hereto that this Agreement not constitute a novation of the obligations
and liabilities existing under the Existing Credit Agreement or evidence repayment of any such obligations and liabilities and that this Agreement amend and restate in its entirety the Existing Credit Agreement and re-evidence the obligations of the
Borrower outstanding thereunder. 
  
 Section 2.04 Requests
for Borrowings. To request a Borrowing, the Borrower shall notify the Administrative Agent (who shall promptly notify the Lenders) of such request by telephone (a) in the case of a Eurodollar Borrowing, not later than 12:00 noon, New York
City time, three Business Days before the date of the proposed Borrowing and (b) in the case of an ABR Borrowing, not later than 12:00 noon, New York City time, on the same Business Day of the proposed Borrowing. Each such telephonic Borrowing
Request shall be irrevocable and shall be confirmed promptly by hand delivery or telecopy to the Administrative Agent of a written 

  

 23 

 
Borrowing Request in substantially the form of Exhibit F and signed by the Borrower or otherwise in a form approved by the Administrative Agent and signed by
the Borrower. Each such telephonic and written Borrowing Request shall specify the following information in compliance with Section 2.02: 
  
 (i) the aggregate amount of the requested Borrowing; 
  
 (ii) the date of such Borrowing, which shall be a Business Day; 
  
 (iii) whether such Borrowing is to be an ABR Borrowing or a
Eurodollar Borrowing; 
  
 (iv) in the case of a
Eurodollar Borrowing, the initial Interest Period to be applicable thereto, which shall be a period contemplated by the definition of the term “Interest Period”; and 
  
 (v) the location and number of the Borrower’s account to which funds are to be disbursed, which shall
comply with the requirements of Section 2.07. 
  
 If no election as to the Type of
Borrowing is specified, then the requested Borrowing shall be an ABR Borrowing. If no Interest Period is specified with respect to any requested Eurodollar Borrowing, then the Borrower shall be deemed to have selected an Interest Period of one
month’s duration. Promptly following receipt of a Borrowing Request in accordance with this Section, the Administrative Agent shall advise each Lender of the details thereof and of the amount of such Lender’s Loan to be made as part of the
requested Borrowing. 
  
 Section 2.05 Extension of Maturity
Date. 
  
 (a) Not earlier than 60 days
prior to, nor later than 45 days prior to, each anniversary of the Effective Date, the Borrower may, upon notice to the Administrative Agent (which shall promptly notify the Lenders), request a one-year extension of the Maturity Date then in effect.
Within 30 days of delivery of such notice, each Lender shall notify the Administrative Agent whether or not it consents to such extension (which consent may be given or withheld in such Lender’s sole and absolute discretion). Any Lender not
responding within the above time period shall be deemed not to have consented to such extension. The Administrative Agent shall promptly notify the Borrower and the Lenders of the Lenders’ responses. 
  
 (b) The Maturity Date shall be extended only if Lenders
holding greater than 51% of the total Commitments then outstanding (calculated excluding any Lender in default in its obligation to fund Loans hereunder and prior to giving effect to any replacements of Lenders permitted herein) (the
“Consenting Lenders”) have consented thereto. If so extended, the Maturity Date, as to the Consenting Lenders, shall be extended to the same date in the following year, effective as of the Maturity Date then in effect (such existing
Maturity Date being the “Extension Effective Date”). The Administrative Agent and the Borrower shall promptly confirm to the Lenders such extension and the Extension Effective Date. As a condition precedent to such extension, the
Borrower shall deliver to the Administrative Agent a certificate of the Borrower dated as of the Extension Effective Date (in sufficient copies for each Lender) 

  

 24 

 
signed by a Responsible Officer of the Borrower (i) certifying and attaching the resolutions adopted by the Borrower approving or consenting to such
extension and (ii) certifying that, (A) before and after giving effect to such extension, the representations and warranties contained in Article III made by it are true and correct on and as of the Extension Effective Date, except to the extent
that such representations and warranties specifically refer to an earlier date, (B) before and after giving effect to such extension no Default exists or will exist, and (C) no event, development or circumstance that has had or could reasonably be
expected to have a Material Adverse Effect has occurred. The Borrower shall prepay any Loans outstanding on the Extension Effective Date (and pay any additional amounts required pursuant to Section 2.16) to the extent necessary to keep outstanding
Loans ratable with any revised and new Applicable Percentages of all the Lenders effective as of the Extension Effective Date. 
  
 (c) If any Lender does not consent to the extension of the Maturity Date as provided in this Section 2.05, the Borrower shall have the
right to replace such Lender in accordance with Section 2.19(b). 
  
 Section 2.06 Letters of Credit. 
  
 (a) General. Subject to the terms and conditions set forth herein, the Borrower may request the issuance of standby Letters of Credit, in dollars and in a form reasonably acceptable to the Administrative Agent and the relevant
Issuing Bank, at any time and from time to time during the Availability Period; provided that the aggregate LC Exposure shall not exceed the lesser of (i) $1,000,000,000 or (ii) the excess of the Total Commitments over the aggregate amount of the
Loans then outstanding; and provided further that, subject to limitations set forth above, no Issuing Bank shall be obligated to front Letters of Credit to extent the LC Exposure associated with Letters of Credit issued by it exceeds $500,000,000.
In the event of any inconsistency between the terms and conditions of this Agreement and the terms and conditions of any form of letter of credit application or other agreement submitted by the Borrower to, or entered into by the Borrower with, the
relevant Issuing Bank relating to any Letter of Credit, the terms and conditions of this Agreement shall control. 
  
 (b) Notice of Issuance, Amendment, Extension; Certain Condition. To request the issuance of a Letter of Credit (or the amendment or
extension of an outstanding Letter of Credit), the Borrower shall hand deliver or telecopy (or transmit by electronic communication, if arrangements for doing so have been approved by the relevant Issuing Bank) to the relevant Issuing Bank and the
Administrative Agent (reasonably in advance of the requested date of issuance, amendment or extension) a notice requesting the issuance of a Letter of Credit, or identifying the Letter of Credit to be amended or extended, and specifying the date of
issuance, amendment or extension (which shall be a Business Day), the date on which such Letter of Credit is to expire (which shall comply with paragraph (c) below), the amount of such Letter of Credit, the name and address of the beneficiary
thereof and such other information as shall be necessary to prepare, amend or extend such Letter of Credit. If requested by the relevant Issuing Bank, the Borrower also shall submit a letter of credit application on its standard form in connection
with any request for a Letter of Credit; provided that no provision in such application shall be deemed effective to the extent such provision contains, provides for, or requires, representations, warranties, covenants, security interests, Liens,
indemnities, reimbursements of costs or expenses, events of defaults, remedies, or standards of care or to the extent such 

  

 25 

 
provision conflicts or is inconsistent with this Agreement. Following receipt of a notice requesting the issuance of a Letter of Credit (or the amendment or
extension of an outstanding Letter of Credit) in accordance with this Section, the Administrative Agent shall advise each Lender of the details thereof. A Letter of Credit shall be issued, amended or extended only if (and upon issuance, amendment or
extension of each Letter of Credit the Borrower shall be deemed to represent and warrant that), after giving effect to such issuance, amendment or extension, the total Credit Exposures shall not exceed the total Commitments. Notwithstanding the
foregoing or anything else to the contrary contained herein, no Issuing Bank shall be under any obligation to issue any Letter of Credit if: (i) any order, judgment or decree of any Governmental Authority or arbitrator shall by its terms purport to
enjoin or restrain such Issuing Bank from issuing such Letter of Credit, or any law applicable to such Issuing Bank or any request or directive (whether or not having the force of law) from any Governmental Authority with jurisdiction over such
Issuing Bank shall prohibit, or request that such Issuing Bank refrain from, the issuance of letters of credit generally or such Letter of Credit in particular or shall impose upon such Issuing Bank with respect to such Letter of Credit any
restriction, reserve or capital requirement (for which such Issuing Bank is not otherwise compensated hereunder) not in effect on the Effective Date, or shall impose upon such Issuing Bank any unreimbursed loss, cost or expense which was not
applicable on the Effective Date and which such Issuing Bank in good faith deems material to it; (ii) the issuance of such Letter of Credit would violate one or more polices of such Issuing Bank (as consistently applied); or (iii) such Letter of
Credit is to be denominated in a currency other than dollars. 
  
 (c) Expiration Date. Each Letter of Credit shall expire at or prior to the close of business on the earlier of (i) the date one year after the date of the issuance of such Letter of Credit (or, in the case of
any renewal or extension thereof, one year after such renewal or extension) and (ii) the date that is five Business Days prior to the Maturity Date then in effect. 
  
 (d) Participation. By the issuance of a Letter of Credit (or an amendment to a Letter of Credit
increasing the amount thereof) and without any further action on the part of an Issuing Bank or the Lenders, such Issuing Bank hereby grants to each Lender, and each Lender hereby acquires from such Issuing Bank, a participation in such Letter of
Credit equal to such Lender’s Applicable Percentage of the aggregate amount available to be drawn under such Letter of Credit. In consideration and in furtherance of the foregoing, each Lender hereby absolutely and unconditionally agrees to pay
to the Administrative Agent, for the account of the relevant Issuing Bank, such Lender’s Applicable Percentage of each LC Disbursement made by such Issuing Bank and not reimbursed by the Borrower on the date due as provided in paragraph (e)
below, or of any reimbursement payment required to be refunded to the Borrower for any reason. Each Lender acknowledges and agrees that its obligation to acquire participations pursuant to this paragraph in respect of Letters of Credit is absolute
and unconditional and shall not be affected by any circumstance whatsoever, including any amendment, renewal or extension of any Letter of Credit or the occurrence and continuance of a Default or reduction or termination of the Commitments, and that
each such payment shall be made without any offset, abatement, withholding or reduction whatsoever. 
  
 (e) Reimbursement. If an Issuing Bank shall make any LC Disbursement in respect of a Letter of Credit, the Borrower shall reimburse
such LC Disbursement by paying to the Administrative Agent an amount equal to such LC Disbursement not later than 1:00 p.m., 

  

 26 

 
New York City time, on the date that such LC Disbursement is made, if the Borrower shall have received notice of such LC Disbursement prior to 11:00 a.m.,
New York City time, on such date, or, if such notice has not been received by the Borrower prior to such time on such date, then not later than 12:00 noon, New York City time, on (i) the Business Day that the Borrower receives such notice, if such
notice is received prior to 11:00 a.m., New York City time, on the day of receipt, or (ii) the Business Day immediately following the day that the Borrower receives such notice, if such notice is not received prior to such time on the day of
receipt; provided that, if such LC Disbursement is not less than $1,000,000, the Borrower may, subject to the conditions to borrowing set forth herein, request in accordance with Section 2.04 that such payment be financed with an ABR Borrowing in an
equivalent amount and, to the extent so financed, the Borrower’s obligation to make such payment shall be discharged and replaced by the resulting ABR Borrowing. If the Borrower fails to make such payment when due, the Administrative Agent
shall notify each Lender of the applicable LC Disbursement, the payment then due from the Borrower in respect thereof and such Lender’s Applicable Percentage thereof. Promptly following receipt of such notice, each Lender shall pay to the
Administrative Agent its Applicable Percentage of the payment then due from the Borrower, in the same manner as provided in Section 2.07 with respect to Loans made by such Lender (and Section 2.07 shall apply, mutatis mutandis, to the payment
obligations of the Lenders), and the Administrative Agent shall promptly pay to the relevant Issuing Bank the amounts so received by it from the Lenders. Promptly following receipt by the Administrative Agent of any payment from the Borrower
pursuant to this paragraph, the Administrative Agent shall distribute such payment to the relevant Issuing Bank or, to the extent that Lenders have made payments pursuant to this paragraph to reimburse such Issuing Bank, then to such Lenders and
such Issuing Bank as its interests may appear. Any payment made by a Lender pursuant to this paragraph to reimburse an Issuing Bank for any LC Disbursement (other than the funding of ABR Loans as contemplated above) shall not constitute a Loan and
shall not relieve the Borrower of its obligation to reimburse such LC Disbursement. 
  
 (f) Obligations Absolute. The Borrower’s obligation to reimburse LC Disbursements as provided in paragraph (e) above shall be
absolute, unconditional and irrevocable, and shall be performed strictly in accordance with the terms of this Agreement under any and all circumstances whatsoever and irrespective of (i) any lack of validity or enforceability of any Letter of Credit
or this Agreement, or any term or provision therein, (ii) any draft or other document presented under a Letter of Credit proving to be forged, fraudulent or invalid in any respect or any statement therein being untrue or inaccurate in any respect,
or (iii) any other event or circumstance whatsoever (other than failure to comply with the terms of such Letter of Credit), whether or not similar to any of the foregoing, that might, but for the provisions of this Section, constitute a legal or
equitable discharge of, or provide a right of setoff against, the Borrower’s obligations hereunder. Neither the Administrative Agent, the Lenders nor the Issuing Banks, nor any of their Related Parties, shall have any liability or
responsibility by reason of or in connection with the issuance or transfer of any Letter of Credit or any payment or failure to make any payment thereunder (irrespective of any of the circumstances referred to in the preceding sentence), or any
error, omission, interruption, loss or delay in transmission or delivery of any draft, notice or other communication under or relating to any Letter of Credit (including any document required to make a drawing thereunder), any error in
interpretation of technical terms or any consequence arising from causes beyond the control of any Issuing Bank; provided that the foregoing shall not be construed to excuse the relevant Issuing Bank from 

  

 27 

 
liability to the Borrower to the extent of any direct damages (as opposed to consequential damages, claims in respect of which are hereby waived by the
Borrower to the extent permitted by applicable law) suffered by the Borrower that are caused by such Issuing Bank’s failure to exercise care when determining whether drafts and other documents presented under a Letter of Credit comply with the
terms thereof. The parties hereto expressly agree that, in the absence of gross negligence or willful misconduct on the part of an Issuing Bank (as finally determined by a court of competent jurisdiction), such Issuing Bank shall be deemed to have
exercised care in each such determination. In furtherance of the foregoing and without limiting the generality thereof, the parties agree that, with respect to documents presented which appear on their face to be in substantial compliance with the
terms of a Letter of Credit, an Issuing Bank may, in its sole discretion, either accept and make payment upon such documents without responsibility for further investigation, regardless of any notice or information to the contrary, or refuse to
accept and make payment upon such documents if such documents are not in strict compliance with the terms of such Letter of Credit. 
  
 (g) Disbursement Procedures. The relevant Issuing Bank shall, promptly following receipt thereof, examine all documents purporting
to represent a demand for payment under a Letter of Credit. The relevant Issuing Bank shall promptly notify the Administrative Agent and the Borrower by telephone (confirmed by telecopy) of such demand for payment and whether it will make an LC
Disbursement thereunder; provided that any failure to give or delay in giving such notice shall not relieve the Borrower of its obligation to reimburse such Issuing Bank and the Lenders with respect to any such LC Disbursement. 
  
 (h) Interim Interest. If an Issuing Bank shall make
any LC Disbursement, then, unless the Borrower shall reimburse such LC Disbursement in full on the date such LC Disbursement is made, the unpaid amount thereof shall bear interest, for each day from and including the date such LC Disbursement is
made to but excluding the date that the Borrower reimburses such LC Disbursement, at the rate per annum then applicable to ABR Loans; provided that, if the Borrower fails to reimburse such LC Disbursement when due pursuant to paragraph (e) above,
then Section 2.13(c) shall apply. Interest accrued pursuant to this paragraph shall be for the account of the relevant Issuing Bank, except that interest accrued on and after the date of payment by any Lender pursuant to paragraph (e) of this
Section to reimburse such Issuing Bank shall be for the account of such Lender to the extent of such payment. 
  
 (i) Replacement of the Issuing Bank. An Issuing Bank may be replaced at any time by written agreement among the Borrower, the
Administrative Agent, the replaced Issuing Bank and the successor Issuing Bank. The Administrative Agent shall notify the Lenders of any such replacement of an Issuing Bank. At the time any such replacement shall become effective, the Borrower shall
pay all unpaid fees accrued for the account of the replaced Issuing Bank pursuant to Section 2.12(b). From and after the effective date of any such replacement, (i) the successor Issuing Bank shall have all the rights and obligations of an Issuing
Bank under this Agreement with respect to Letters of Credit to be issued thereafter and (ii) references herein to the term “Issuing Bank” shall be deemed to refer to such successor or to any previous Issuing Bank, or to such successor and
all previous Issuing Banks, as the context shall require. After the replacement of an Issuing Bank hereunder, the replaced Issuing Bank shall remain a party hereto and shall continue to have all the rights and obligations of an Issuing Bank under
this Agreement

with respect to Letters of Credit issued by it prior to such replacement, but shall not be required to issue additional Letters of Credit. 
  
 (j) Cash Collateralization. If any Event of Default
shall occur and be continuing, then on the Business Day that the Borrower receives notice from the Administrative Agent (at the direction of Required Lenders) or the Required Lenders demanding the deposit of cash collateral pursuant to this
paragraph, the Borrower shall deposit in an account with the Administrative Agent, in the name of the Administrative Agent and for the benefit of the Lenders, an amount in cash equal to the LC Exposure as of such date plus any accrued and unpaid
interest and fees thereon; provided that the obligation to deposit such cash collateral shall become effective immediately, and such deposit shall be come immediately due and payable, without demand or other notice of any kind, upon the occurrence
of any Event of Default with respect to the Borrower described in clause (h) or (i) of Article VII. Such deposit shall be held by the Administrative Agent as collateral for the payment and performance of the obligations of the Borrower under this
Agreement. The Administrative Agent shall have exclusive dominion and control, including the exclusive right of withdrawal, over such account (which shall be invested in obligations of, obligations guaranteed by, or obligations backed by the full
faith and credit of, the United States of America, certificates of deposit of Administrative Agent or commercial paper having the highest rating from S&P or Moody’s, in each case maturing in less than 180 days). Other than any interest
earned on the investment of such deposits, which investments shall be made at the option and sole discretion of the Administrative Agent and at the Borrower’s risk and expense, such deposits shall not bear interest. Interest or profits, if any,
on such investments shall accumulate in such account. Moneys in such account shall be applied by the Administrative Agent to reimburse ratably the Issuing Banks for LC Disbursements for which they have not been reimbursed and, to the extent not so
applied, shall be held for the satisfaction of the reimbursement obligations of the Borrower for the LC Exposure at such time or, if the maturity of the Loans has been accelerated (but subject to the consent of Lenders with LC Exposure representing
greater than 50% of the total LC Exposure), be applied to satisfy other obligations of the Borrower under this Agreement. 
  
 (k) Outstanding Letters of Credit. On the Effective Date, the Letters of Credit listed on Schedule 2.06 shall be (i) transferred to
the Borrower by novation (and each applicant thereto shall be fully released and discharged from its obligations thereunder) and (ii) deemed to have been issued under this Agreement by JPMorgan Chase Bank, N.A., as an Issuing Bank, or U.S. Bank
National Association, as Issuing Bank, as specified on Schedule 2.06, without payment of any fees otherwise due upon the issuance of a Letter of Credit, and JPMorgan Chase Bank, N.A. and U.S. Bank National Association, as Issuing Banks, shall be
deemed, without further action by any party hereto, to have sold to each Lender, and each Lender shall be deemed, without further action by any party hereto, to have purchased from JPMorgan Chase Bank, N.A. and U.S. Bank National Association, as
Issuing Banks, a participation, to the extent of such Lender’s Applicable Percentage, in such Letters of Credit. 
  
 Section 2.07 Funding of Borrowings. 
  
 (a) Each Lender shall make each Loan to be made by it hereunder on the proposed date thereof by wire transfer of immediately available
funds by 1:00 pm, New York City time, to the account of the Administrative Agent most recently designated by it for such 

  

 29 

 
purpose by notice to the Lenders (provided that in the case of the initial Borrowing hereunder, if the Borrower has specified in a written Borrowing Request
related to such proposed Borrowing furnished in accordance with Section 2.04 that funds should be disbursed by 9:00 a.m., New York City time on the date of such proposed Borrowing, then each Lender shall make the Loan to be made by it on the
proposed date of such Borrowing by wire transfer of immediately available funds as aforesaid by 9:00 a.m., New York City time). The Administrative Agent will make such Loans available to the Borrower by promptly crediting the amounts so received, in
like funds, to an account of the Borrower maintained with the Administrative Agent and designated by the Borrower in the applicable Borrowing Request; provided that ABR Loans made to finance the reimbursement of an LC Disbursement as provided in
Section 2.06(e) shall be remitted by the Administrative Agent to the relevant Issuing Bank. 
  
 (b) Unless the Administrative Agent shall have received notice from a Lender prior to the proposed time of any Borrowing that such Lender
will not make available to the Administrative Agent such Lender’s share of such Borrowing, the Administrative Agent may assume that such Lender has made such share available in accordance with paragraph (a) of this Section and may, in reliance
upon such assumption, make available to the Borrower a corresponding amount. In such event, if a Lender has not in fact made its share of the applicable Borrowing available to the Administrative Agent, then the applicable Lender and the Borrower
severally agree to pay to the Administrative Agent forthwith on demand such corresponding amount with interest thereon, for each day from and including the date such amount is made available to the Borrower to but excluding the date of payment to
the Administrative Agent, at (i) in the case of such Lender, the greater of the Federal Funds Effective Rate and a rate determined by the Administrative Agent in accordance with banking industry rules on interbank compensation or (ii) in the case of
the Borrower, the interest rate applicable to the applicable Borrowing. If such Lender pays such amount to the Administrative Agent, then such amount shall constitute such Lender’s Loan included in such Borrowing. 
  
 Section 2.08 Interest Elections. 
  
 (a) Each Borrowing initially shall be of the Type specified
in the applicable Borrowing Request and, in the case of a Eurodollar Borrowing, shall have an initial Interest Period as specified in such Borrowing Request. Thereafter, the Borrower may elect to convert such Borrowing to a different Type or to
continue such Borrowing and, in the case of a Eurodollar Borrowing, may elect Interest Periods therefor, all as provided in this Section. The Borrower may elect different options with respect to different portions of the affected Borrowing, in which
case each such portion shall be allocated ratably among the Lenders holding the Loans comprising such Borrowing, and the Loans comprising each such portion shall be considered a separate Borrowing. 
  
 (b) To make an election pursuant to this Section, the
Borrower shall notify the Administrative Agent of such election by telephone by the time that a Borrowing Request would be required under Section 2.04 if the Borrower were requesting a Borrowing of the Type resulting from such election to be made on
the effective date of such election. Each such telephonic Interest Election Request shall be irrevocable and shall be confirmed promptly by hand delivery or telecopy to the Administrative Agent of a written Interest Election Request 

  

 30 

 
substantially in the form of Exhibit G or otherwise in a form approved by the Administrative Agent and signed by the Borrower. 
  
 (c) Each telephonic and written Interest Election Request
shall specify the following information in compliance with Section 2.02: 
  
 (i) the Borrowing to which such Interest Election Request applies and, if different options are being elected with respect to different portions thereof, the portions thereof to be allocated to each resulting
Borrowing (in which case the information to be specified pursuant to clauses (iii) and (iv) below shall be specified for each resulting Borrowing); 
  
 (ii) the effective date of the election made pursuant to such Interest Election Request, which shall be a Business Day; 
  
 (iii) whether the resulting Borrowing is to be an ABR
Borrowing or a Eurodollar Borrowing; and 
  
 (iv)
if the resulting Borrowing is a Eurodollar Borrowing, the Interest Period to be applicable thereto after giving effect to such election, which shall be a period contemplated by the definition of the term “Interest Period”. 
  
 If any such Interest Election Request requests a Eurodollar Borrowing but does not specify an
Interest Period, then the Borrower shall be deemed to have selected an Interest Period of one month’s duration. 
  
 (d) Promptly following receipt of an Interest Election Request, the Administrative Agent shall advise each Lender of the details thereof
and of such Lender’s portion of each resulting Borrowing. 
  
 (e) If the Borrower fails to deliver a timely Interest Election Request with respect to a Eurodollar Borrowing prior to the end of the Interest Period applicable thereto, then, unless such Borrowing is repaid as
provided herein, at the end of such Interest Period such Borrowing shall be converted to an ABR Borrowing. Notwithstanding any contrary provision hereof, if an Event of Default has occurred and is continuing and the Administrative Agent, at the
request of the Required Lenders, so notifies the Borrower, then, so long as an Event of Default is continuing (i) no outstanding Borrowing may be converted to or continued as a Eurodollar Borrowing and (ii) unless repaid, each Eurodollar Borrowing
shall be converted to an ABR Borrowing at the end of the Interest Period applicable thereto. 
  
 Section 2.09 Termination and Reduction of Commitments. 
  
 (a) Unless previously terminated, the Commitments shall terminate on the Maturity Date. 
  
 (b) The Borrower may at any time terminate, or from time to
time, reduce the Commitments; provided that (i) each reduction of the Commitments shall be in an amount that is an integral multiple of $1,000,000 and not less than $5,000,000 and (ii) the Borrower shall not 

  

 31 

 
terminate or reduce the Commitments if, after giving effect to any concurrent prepayment of the Loans in accordance with Section 2.11, the Credit Exposure
would exceed the Commitments. 
  
 (c) The
Borrower shall notify the Administrative Agent of any election to terminate or reduce the Commitments under paragraph (b) of this Section at least three Business Days prior to the effective date of such termination or reduction, specifying such
election and the effective date thereof. Promptly following receipt of any notice, the Administrative Agent shall advise the Lenders of the contents thereof. Each notice delivered by the Borrower pursuant to this Section shall be irrevocable;
provided that a notice of termination of the Commitments delivered by the Borrower may state that such notice is conditioned upon the effectiveness of other credit facilities, in which case such notice may be revoked by the Borrower (by notice to
the Administrative Agent on or prior to the specified effective date) if such condition is not satisfied. Any termination or reduction of the Commitments shall be permanent. Each reduction of the Commitments shall be made ratably among the Lenders
in accordance with their respective Applicable Percentage. 
  
 Section 2.10 Repayment of Loans; Evidence of Debt. 
  
 (a) The Borrower hereby unconditionally promises to pay to the Administrative Agent for the account of each Lender the then unpaid principal amount of each Loan on the Maturity Date. 
  
 (b) Each Lender shall maintain in accordance with its usual
practice an account or accounts evidencing the indebtedness of the Borrower to such Lender resulting from each Loan made by such Lender, including the amounts of principal and interest payable and paid to such Lender from time to time hereunder.

  
 (c) The Administrative Agent shall maintain
accounts in which it shall record (i) the amount of each Loan made hereunder, the Type thereof and the Interest Period applicable thereto, (ii) the amount of any principal or interest due and payable or to become due and payable from the Borrower to
each Lender hereunder and (iii) the amount of any sum received by the Administrative Agent hereunder for the account of the Lenders and each Lender’s share thereof. 
  
 (d) The entries made in the accounts maintained pursuant to paragraph (b) or (c) of this Section shall be
prima facie evidence of the existence and amounts of the obligations recorded therein; provided that the failure of any Lender or the Administrative Agent to maintain such accounts or any error therein shall not in any manner affect the
obligation of the Borrower to repay the Loans in accordance with the terms of this Agreement. 
  
 (e) Any Lender may request that Loans made by it be evidenced by a promissory note. In such event, the Borrower shall prepare, execute and
deliver to such Lender a promissory note payable to the order of such Lender (or, if requested by such Lender, to such Lender and its registered assigns) and substantially in the form attached hereto as Exhibit E. Thereafter, the Loans evidenced by
such promissory note and interest thereon shall at all times (including after assignment pursuant to Section 9.04) be represented by one or more promissory 

  

 32 

 
notes in such form payable to the order of the payee named therein (or, if such promissory note is a registered note, to such payee and its registered
assigns). 
  
 Section 2.11 Prepayment of Loans.

  
 (a) Subject to any breakage funding costs
payable pursuant to Section 2.16, the Borrower shall have the right at any time and from time to time to prepay any Borrowing in whole or in part without premium or penalty, provided that each prepayment is in an amount that is an integral multiple
of $1,000,000 and not less than $1,000,000, or if such amount is lesser, the outstanding amount of the Borrowing, and made subject to prior notice in accordance with paragraph (b) of this Section. 
  
 (b) The Borrower shall notify the Administrative Agent by
telephone (confirmed by telecopy) of any prepayment hereunder (i) in the case of prepayment of a Eurodollar Borrowing, not later than 12:00 noon, New York City time, one Business Day before the date of prepayment or (ii) in the case of prepayment of
an ABR Borrowing, not later than 12:00 noon, New York City time, on the date of prepayment. Each such notice shall be irrevocable and shall specify the prepayment date and the principal amount of each Borrowing or portion thereof to be prepaid;
provided that, if a notice of prepayment is given in connection with a conditional notice of termination of the Commitments as contemplated by Section 2.09, then such notice of prepayment may be revoked if such notice of termination is revoked in
accordance with Section 2.09. Promptly following receipt of any such notice relating to a Borrowing, the Administrative Agent shall advise the Lenders of the contents thereof. Each partial prepayment of any Borrowing shall be in an amount that would
be permitted in the case of an advance of a Borrowing of the same Type as provided in Section 2.02. Each prepayment of a Borrowing shall be applied ratably to the Loans included in the prepaid Borrowing. Prepayments shall be accompanied by accrued
interest to the extent required by Section 2.13. 
  
 Section
2.12 Fees. 
  
 (a) The Borrower agrees
to pay to the Administrative Agent for the account of each Lender a commitment fee, which shall accrue at the Applicable Margin for commitment fees on the daily amount of the unused Commitment of such Lender during the period from and including the
date hereof to but excluding the date on which such Commitment terminates. Accrued Commitment fees shall be payable in arrears on the last day of March, June, September and December of each year and on the date on which the Commitments terminate,
commencing on March 31, 2005. All Commitment fees shall be computed on the basis of a year of 365 days (or 366 days in a leap year) and shall be payable for the actual number of days elapsed (including the first day but excluding the last day).

  
 (b) The Borrower agrees to pay (i) to the
Administrative Agent for the account of each Lender a participation fee with respect to its participations in Letters of Credit, which shall accrue at the same Applicable Margin used to determine the interest rate applicable to Eurodollar Loans on
the average daily amount of such Lender’s LC Exposure (excluding any portion thereof attributable to unreimbursed LC Disbursements) during the period from and including the Effective Date to but excluding the later of the date on which such
Lender’s Commitment terminates and the date on which such Lender ceases to have any LC Exposure, 

  

 33 

 
and (ii) to each Issuing Bank a fronting fee, which shall accrue at the rate of 0.125% per annum on the average daily amount (except in the case of Letters
of Credit issued by Bank of America, N.A., as Issuing Bank, which rate shall accrue on the daily amount) of the LC Exposure associated with Letters of Credit issued by such Issuing Bank (excluding any portion thereof attributable to unreimbursed LC
Disbursements) during the period from and including the Effective Date to but excluding the later of the date of termination of the Commitments and the date on which there ceases to be any LC Exposure, as well as such Issuing Bank’s standard
fees with respect to the issuance, amendment, renewal or extension of any Letter of Credit or processing of drawings thereunder. Participation fees and fronting fees shall be payable in arrears on the last day of March, June, September and December
of each year and on the date on which the Commitments terminate, commencing on June 30, 2005. All participation fees and fronting fees shall be computed on the basis of a year of 365 days (or 366 days in a leap year) and shall be payable for the
actual number of days elapsed (including the first day but excluding the last day). 
  
 (c) The Borrower agrees to pay to the Administrative Agent, for its own account, fees payable in the amounts and at the times separately
agreed upon in writing between the Borrower and the Administrative Agent. 
  
 (d) All fees payable hereunder shall be paid on the dates due, in immediately available funds, to the Administrative Agent (or to each Issuing Bank, in the case of fees payable to it) for distribution, in the case of
commitment fees and participation fees, to the Lenders. Fees paid shall not be refundable under any circumstances. 
  
 Section 2.13 Interest. 
  
 (a) The Loans comprising each ABR Borrowing shall bear interest at the Alternate Base Rate plus the Applicable Margin, but not to exceed
the Highest Lawful Rate. 
  
 (b) The Loans
comprising each Eurodollar Borrowing shall bear interest at the Adjusted LIBO Rate for the Interest Period in effect for such Borrowing plus the Applicable Margin, but not to exceed the Highest Lawful Rate. 
  
 (c) Notwithstanding the foregoing, if any principal of or
interest on any Loan or any fee or other amount payable by the Borrower hereunder is not paid when due, whether at stated maturity, upon acceleration or otherwise, such overdue amount shall bear interest, after as well as before judgment, at a rate
per annum equal to (i) in the case of overdue principal of any Loan, 2% plus the rate otherwise applicable to such Loan as provided in the preceding paragraphs of this Section or (ii) in the case of any other amount, 2% plus the rate applicable to
ABR Loans as provided in paragraph (a) of this Section, but not to exceed the Highest Lawful Rate. 
  
 (d) Accrued interest on each Loan shall be payable in arrears on each Interest Payment Date for such Loan and upon termination of the
Commitments; provided that (i) interest accrued pursuant to paragraph (c) of this Section shall be payable on demand, (ii) in the event of any repayment or prepayment of any Loan (other than a prepayment of an ABR Loan prior to the end of the
Availability Period), accrued interest on the principal amount repaid or prepaid shall 

  

 34 

 
be payable on the date of such repayment or prepayment and (iii) in the event of any conversion of any Eurodollar Loan prior to the end of the current
Interest Period therefor, accrued interest on such Loan shall be payable on the effective date of such conversion. 
  
 (e) All interest hereunder shall be computed on the basis of a year of 360 days, except that interest computed by reference to the
Alternate Base Rate shall be computed on the basis of a year of 365 days (or 366 days in a leap year), and in each case shall be payable for the actual number of days elapsed (including the first day but excluding the last day). The applicable
Alternate Base Rate, Adjusted LIBO Rate or LIBO Rate shall be determined by the Administrative Agent and such determination shall be conclusive absent manifest error. 
  
 Section 2.14 Alternate Rate of Interest. If prior to the commencement of any Interest Period for a Eurodollar
Borrowing: 
  
 (a) the Administrative Agent
determines (which determination shall be conclusive absent manifest error) that adequate and reasonable means do not exist for ascertaining the Adjusted LIBO Rate or the LIBO Rate, as applicable, for such Interest Period; or 
  
 (b) the Administrative Agent is advised by the Required
Lenders that the Adjusted LIBO Rate or the LIBO Rate, as applicable, for such Interest Period will not adequately and fairly reflect the cost to such Lenders of making or maintaining their Loans included in such Borrowing for such Interest Period;

  
 then the Administrative Agent shall give notice thereof to the Borrower and
the Lenders by telephone or telecopy as promptly as practicable thereafter and, until the Administrative Agent notifies the Borrower and the Lenders that the circumstances giving rise to such notice no longer exist, (i) any Interest Election Request
that requests the conversion of any Borrowing to, or continuation of any Borrowing as, a Eurodollar Borrowing shall be ineffective and (ii) if any Borrowing Request requests a Eurodollar Borrowing, such Borrowing shall be made as an ABR Borrowing.

  
 Section 2.15 Increased Costs. 
  
 (a) If any Change in Law shall: 
  
 (i) impose, modify or deem applicable any reserve, special
deposit or similar requirement against assets of, deposits with or for the account of, or credit extended by, any Lender (except any such reserve requirement reflected in the Adjusted LIBO Rate) or any Issuing Bank; or 
  
 (ii) impose on any Lender or any Issuing Bank or the London
interbank market any other condition affecting this Agreement or Eurodollar Loans made by such Lender or any Letter of Credit or participation therein (excluding, in each case, Taxes, as to which Section 2.17 shall govern) and the result of any of
the foregoing shall be to increase the cost to such Lender of making or maintaining any Eurodollar Loan (or of maintaining its obligation to make any such Loan) or to increase the cost to such Lender or Issuing Bank of participating in, issuing or
maintaining any Letter of Credit or to reduce the amount of any sum received or receivable by such Lender or Issuing Bank hereunder (whether of principal, interest 

  

 35 

 
or otherwise), then the Borrower will pay to such Lender or Issuing Bank, as the case may be, such additional amount or amounts as will compensate such
Lender or Issuing Bank, as the case may be, for such additional costs incurred or reduction suffered. 
  
 (b) If any Lender or Issuing Bank determines that any Change in Law regarding capital requirements has or would have the effect of
reducing the rate of return on such Lender’s or Issuing Bank’s capital or on the capital of such Lender’s or Issuing Bank’s holding company, if any, as a consequence of this Agreement or the Loans made by, or participations in
Letters of Credit held by, such Lender, or the Letters of Credit issued by Issuing Bank, to a level below that which such Lender or Issuing Bank or such Lender’s or the Issuing Bank’s holding company could have achieved but for such Change
in Law (taking into consideration such Lender’s or Issuing Bank’s policies and the policies of such Lender’s or the Issuing Bank’s holding company with respect to capital adequacy), then from time to time the Borrower will pay to
such Lender or Issuing Bank, as the case may be, such additional amount or amounts as will compensate such Lender or Issuing Bank or such Lender’s or Issuing Bank’s holding company for any such reduction suffered. 
  
 (c) A certificate of a Lender or Issuing Bank setting forth
in reasonable detail the amount or amounts necessary to compensate such Lender or Issuing Bank or its holding company, as the case may be, as specified in paragraph (a) or (b) of this Section shall be delivered to the Borrower and shall be
conclusive absent manifest error. The Borrower shall pay to the Administrative Agent for the account of such Lender or Issuing Bank, as the case may be, the amount shown as due on any such certificate within 10 days after receipt thereof.

  
 (d) Failure or delay on the part of any
Lender or Issuing Bank to demand compensation pursuant to this Section shall not constitute a waiver of such Lender’s or Issuing Bank’s right to demand such compensation; provided that the Borrower shall not be required to compensate a
Lender or Issuing Bank pursuant to this Section for any increased costs or reductions incurred more than 180 days prior to the date that such Lender or Issuing Bank, as the case may be, notifies the Borrower of the Change in Law giving rise to such
increased costs or reductions and of such Lender’s or Issuing Bank’s intention to claim compensation therefor; provided further that, if the Change in Law giving rise to such increased costs or reductions is retroactive, then the 180-day
period referred to above shall be extended to include the period of retroactive effect thereof. 
  
 Section 2.16 Break Funding Payments. In the event of (a) the payment of any principal of any Eurodollar Loan other than on the last day of
an Interest Period applicable thereto (including as a result of an Event of Default), (b) the conversion of any Eurodollar Loan other than on the last day of the Interest Period applicable thereto, (c) the failure to borrow, convert, continue or
prepay any Eurodollar Loan on the date specified in any notice delivered pursuant hereto (regardless of whether such notice may be revoked under Section 2.11(b) and is revoked in accordance therewith), or (d) the assignment of any Eurodollar Loan
other than on the last day of the Interest Period applicable thereto as a result of a request by the Borrower pursuant to Section 2.19, then, in any such event, the Borrower shall compensate each Lender for the loss, cost and expense attributable to
such event. In the case of a Eurodollar Loan, such loss, cost or expense to any Lender shall be deemed to include an amount determined by such Lender to be the excess, if any, of (i) the amount of interest which would have accrued on the principal

  

 36 

 
amount of such Loan had such event not occurred, at the Adjusted LIBO Rate that would have been applicable to such Loan, for the period from the date of such
event to the last day of the then current Interest Period therefor (or, in the case of a failure to borrow, convert or continue, for the period that would have been the Interest Period for such Loan), over (ii) the amount of interest which would
accrue on such principal amount for such period at the interest rate which such Lender would bid were it to bid, at the commencement of such period, for dollar deposits of a comparable amount and period from other banks in the eurodollar market. A
certificate of any Lender setting forth any amount or amounts that such Lender is entitled to receive pursuant to this Section in reasonable detail shall be delivered to the Borrower and shall be conclusive absent manifest error. The Borrower shall
pay to the Administrative Agent for the account of such Lender the amount shown as due on any such certificate within 10 days after receipt thereto. 
  
 Section 2.17 Taxes. 
  
 (a) Any and all payments by or on account of any obligation of the Borrower hereunder shall be made free and clear of and without
deduction for any Indemnified Taxes or Other Taxes; provided that if the Borrower shall be required to deduct any Indemnified Taxes or Other Taxes from such payments, then (i) the sum payable shall be increased as necessary so that after making all
required deductions (including deductions applicable to additional sums payable under this Section) the Administrative Agent, Lender, or an Issuing Bank (as the case may be) receives an amount equal to the sum it would have received had no such
deductions been made, (ii) the Borrower shall make such deductions and (iii) the Borrower shall pay the full amount deducted to the relevant Governmental Authority in accordance with applicable law. 
  
 (b) In addition, the Borrower shall pay any Other Taxes to
the relevant Governmental Authority in accordance with applicable law. 
  
 (c) The Borrower shall indemnify the Administrative Agent, each Lender, and each Issuing Bank within 10 days after written demand therefor, for the full amount of any Indemnified Taxes or Other Taxes paid by the
Administrative Agent, such Lender, or such Issuing Bank, as the case may be, on or with respect to any payment by or on account of any obligation of the Borrower hereunder (including Indemnified Taxes or Other Taxes imposed or asserted on or
attributable to amounts payable under this Section) and any penalties, interest and reasonable expenses arising therefrom or with respect thereto, whether or not such Indemnified Taxes or Other Taxes were correctly or legally imposed or asserted by
the relevant Governmental Authority. A certificate as to the amount of such payment or liability in reasonable detail shall be delivered to the Borrower by a Lender or Issuing Bank, or by the Administrative Agent on its own behalf or on behalf of a
Lender or Issuing Bank and shall be conclusive absent manifest error. 
  
 (d) As soon as practicable after any payment of Indemnified Taxes or Other Taxes by the Borrower to a Governmental Authority, the Borrower shall deliver to the Administrative Agent the original or a certified copy of
a receipt issued by such Governmental Authority evidencing such payment, a copy of the return reporting such payment or other evidence of such payment reasonably satisfactory to the Administrative Agent. 
  

 37 

 (e) Any Foreign Lender that is entitled to an exemption from or reduction of withholding
tax under the law of the jurisdiction in which the Borrower is located, or any treaty to which such jurisdiction is a party, with respect to payments under this Agreement shall deliver to the Borrower (with a copy to the Administrative Agent), at
the time or times prescribed by applicable law, such properly completed and executed documentation prescribed by applicable law or reasonably requested by the Borrower as will permit such payments to be made without withholding or at a reduced rate.

  
 (f) Upon the Borrower’s written request,
the Administrative Agent and each Lender shall use reasonable efforts to make any filings necessary to obtain any refund, deduction or credit of any Taxes or Other Taxes as to which the Borrower has indemnified it or with respect to which the
Borrower has paid additional amounts pursuant to this Section 2.17. If the Administrative Agent or a Lender determines that it has received a refund of any Taxes or Other Taxes as to which it has been indemnified by the Borrower or with respect to
which the Borrower has paid additional amounts pursuant to this Section 2.17, it shall pay over such refund to the Borrower (but only to the extent of indemnity payments made, or additional amounts paid, by the Borrower under this Section 2.17 with
respect to the Taxes or Other Taxes giving rise to such refund), net of all reasonable out-of-pocket expenses of the Administrative Agent or such Lender and without interest (other than any interest paid by the relevant Governmental Authority with
respect to such refund); provided, that the Borrower, upon the request of the Administrative Agent or such Lender, agrees to repay the amount paid over to the Borrower (plus any penalties, interest or other charges imposed by the relevant
Governmental Authority) to the Administrative Agent or such Lender in the event the Administrative Agent or such Lender is required to repay such refund to such Governmental Authority. This Section shall not be construed to require the
Administrative Agent or any Lender to make available its tax returns (or any other information relating to its taxes which it deems confidential) to the Borrower or any other Person or to attempt to take any position to obtain a refund, deduction,
or credit, which attempt would be inconsistent with any reporting position otherwise taken by the Administrative Agent or such Lender on its applicable tax returns. 
  
 Section 2.18 Payments Generally; Pro Rata Treatment; Sharing of Set-offs. 
  
 (a) The Borrower shall make each payment required to be made
by it hereunder (whether of principal, interest, fees or reimbursement of LC Disbursements, or of amounts payable under Section 2.15, 2.16 or 2.17, or otherwise) prior to 2:00 p.m., New York City time, on the date when due, in immediately available
funds, without set-off or counterclaim. Any amounts received after such time on any date may, in the discretion of the Administrative Agent, be deemed to have been received on the next succeeding Business Day for purposes of calculating interest
thereon. All such payments shall be made to the Administrative Agent at such offices as it may designate from time to time, except payments to be made directly to each Issuing Bank as expressly provided herein and except that payments pursuant to
Sections 2.15, 2.16, 2.17 and 9.03 shall be made directly to the Persons entitled thereto. The Administrative Agent shall distribute any such payments received by it for the account of any other Person to the appropriate recipient promptly following
receipt thereof. If any payment hereunder shall be due on a day that is not a Business Day, the date for payment shall be extended to the next succeeding Business Day, and, in the case of any payment accruing interest, interest thereon 

  

 38 

 
shall be payable for the period of such extension. All payments hereunder shall be made in dollars. 
  
 (b) If at any time insufficient funds are received by and
available to the Administrative Agent to pay fully all amounts of principal, unreimbursed LC Disbursements, interest and fees then due hereunder, such funds shall be applied (i) first, towards payment of interest and fees then due hereunder, ratably
among the parties entitled thereto in accordance with the amounts of interest and fees then due to such parties, and (ii) second, towards payment of principal and unreimbursed LC Disbursements then due hereunder, ratably among the parties entitled
thereto in accordance with the amounts of principal and unreimbursed LC Disbursements then due to such parties. 
  
 (c) If any Lender shall, by exercising any right of set-off or counterclaim or otherwise, obtain payment in respect of any principal of or
interest on any of its Loans or participations in LC Disbursements resulting in such Lender receiving payment of a greater proportion of the aggregate amount of its Loans and participations in LC Disbursements and accrued interest thereon than the
proportion received by any other Lender, then the Lender receiving such greater proportion shall purchase (for cash at face value) participations in the Loans and participations in LC Disbursements of other Lenders to the extent necessary so that
the benefit of all such payments shall be shared by the Lenders ratably in accordance with the aggregate amount of principal of and accrued interest on their respective Loans and participations in LC Disbursements; provided that (i) if any such
participations are purchased and all or any portion of the payment giving rise thereto is recovered, such participations shall be rescinded and the purchase price restored to the extent of such recovery, without interest, and (ii) the provisions of
this paragraph shall not be construed to apply to any payment made by the Borrower pursuant to and in accordance with the express terms of this Agreement or any payment obtained by a Lender as consideration for the assignment of or sale of a
participation in any of its Loans or participations in LC Disbursements to any assignee or participant, other than to the Borrower or any Subsidiary or Affiliate thereof (as to which the provisions of this paragraph shall apply). The Borrower
consents to the foregoing and agrees, to the extent it may effectively do so under applicable law, that any Lender acquiring a participation pursuant to the foregoing arrangements may exercise against the Borrower rights of set-off and counterclaim
with respect to such participation as fully as if such Lender were a direct creditor of the Borrower in the amount of such participation. 
  
 (d) Unless the Administrative Agent shall have received notice from the Borrower prior to the date on which any payment is due to the
Administrative Agent for the account of the Lenders or the Issuing Banks hereunder that the Borrower will not make such payment, the Administrative Agent may assume that the Borrower has made such payment on such date in accordance herewith and may,
in reliance upon such assumption, distribute to the Lenders or the Issuing Banks, as the case may be, the amount due. In such event, if the Borrower has not in fact made such payment, then each of the Lenders or the Issuing Banks, as the case may
be, severally agrees to repay to the Administrative Agent forthwith on demand the amount so distributed to such Lender or Issuing Bank with interest thereon, for each day from and including the date such amount is distributed to it to but excluding
the date of payment to the Administrative Agent, at the greater of the Federal Funds Effective Rate and a rate determined 

  

 39 

 
by the Administrative Agent in accordance with banking industry rules on interbank compensation. 
  
 (e) If any Lender shall fail to make any payment required to
be made by it pursuant to Section 2.06(d) or (e), 2.07(b) or 2.18(d), then the Administrative Agent may, in its discretion (notwithstanding any contrary provision hereof), apply any amounts thereafter received by the Administrative Agent for the
account of such Lender to satisfy such Lender’s obligations under such Sections until all such unsatisfied obligations are fully paid. 
  
 Section 2.19 Mitigation Obligations; Replacement of Lenders. 
  
 (a) If any Lender requests compensation under Section 2.15, or if the Borrower is required to pay any
additional amount to any Lender or any Governmental Authority for the account of any Lender pursuant to Section 2.17, then such Lender shall use reasonable efforts to designate a different lending office for funding or booking its Loans hereunder or
to assign its rights and obligations hereunder to another of its offices, branches or affiliates, if, in the judgment of such Lender, such designation or assignment (i) would eliminate or reduce amounts payable pursuant to Section 2.15 or 2.17, as
the case may be, in the future and (ii) would not subject such Lender to any unreimbursed cost or expense and would not otherwise be disadvantageous to such Lender. The Borrower hereby agrees to pay all reasonable costs and expenses incurred by any
Lender in connection with any such designation or assignment. 
  
 (b) If any Lender or its Participant requests compensation under Section 2.15, or if the Borrower is required to pay any additional amount to any Lender, its Participant or any Governmental Authority for the account
of any Lender or its Participant pursuant to Section 2.17, or if any Lender defaults in its obligation to fund Loans hereunder, or if any Lender shall fail to agree to extend the Maturity Date pursuant to Section 2.05, if the requisite Lenders have
agreed to do so, then the Borrower may, at its sole expense and effort, upon notice to such Lender and the Administrative Agent, require such Lender to assign and delegate, without recourse (in accordance with and subject to the restrictions
contained in Section 9.04), all its interests, rights and obligations under this Agreement to an assignee that shall assume such obligations (which assignee may be a Lender, if a Lender accepts such assignment); provided that (i) the Borrower shall
have received the prior written consent of the Administrative Agent (and, if a Commitment is being assigned, each Issuing Bank) which consent shall not unreasonably be withheld, (ii) such Lender or its Participant shall have received payment of an
amount equal to the outstanding principal of its Loans and participations in LC Disbursements, accrued interest thereon, accrued fees and all other amounts payable to it hereunder, from the assignee (to the extent of such outstanding principal and
accrued interest and fees) or the Borrower (in the case of all other amounts) and (iii) in the case of any such assignment resulting from a claim for compensation under Section 2.15 or payments required to be made pursuant to Section 2.17, such
assignment will result in a reduction in such compensation or payments. A Lender shall not be required to make any such assignment and delegation if, prior thereto, as a result of a waiver by such Lender, its Participant or otherwise, the
circumstances entitling the Borrower to require such assignment and delegation cease to apply. 
  
 Section 2.20 Illegality. Notwithstanding any other provision of this Agreement, in the event that it becomes unlawful for any Lender or its applicable lending office to honor its 

  

 40 

 
obligation to make or maintain Eurodollar Loans either generally or having a particular Interest Period hereunder, then (a) such Lender shall promptly notify
the Borrower and the Administrative Agent thereof and such Lender’s obligation to make such Eurodollar Loans shall be suspended (the “Affected Loans”) until such time as such Lender may again make and maintain such Eurodollar
Loans and (b) all Affected Loans which would otherwise be made by such Lender shall be made instead as ABR Loans (and, if such Lender so requests by notice to the Borrower and the Administrative Agent, all Affected Loans of such Lender then
outstanding shall be automatically converted into ABR Loans on the date specified by such Lender in such notice) and, to the extent that Affected Loans are so made as (or converted into) ABR Loans, all payments of principal which would otherwise be
applied to such Lender’s Affected Loans shall be applied instead to its ABR Loans. 
  
 ARTICLE III 
 REPRESENTATIONS AND WARRANTIES 
  
 The Borrower represents and warrants to the Lenders that: 
  
 Section 3.01 Organization; Powers. Each of the Borrower and its
Restricted Subsidiaries is duly organized, validly existing and in good standing under the laws of the jurisdiction of its organization, has all requisite power and authority to carry on its business as now conducted and, except where the failure to

 Section 3.02 Authorization; Enforceability. The Transactions
are within each Obligor’s corporate powers and have been duly authorized by all necessary corporate and, if required, stockholder action. This Agreement and all Subsidiary Guaranties have been duly executed and delivered by the Obligor, which
is a party thereto, and constitute a legal, valid and binding obligation of such Obligor, enforceable in accordance with their terms, subject to applicable bankruptcy, insolvency, reorganization, moratorium or other laws affecting creditors’
rights generally and subject to general principles of equity, regardless of whether considered in a proceeding in equity or at law. 
  
 Section 3.03 Governmental Approvals; No Conflicts. The Transactions do not (a) violate the charter, by-laws or other organizational
documents of the Borrower or any of its Restricted Subsidiaries, (b) require any consent or approval of, registration or filing with, or any other action by, any Governmental Authority, except such as have been obtained or made and are in full force
and effect, (c) violate any applicable law or regulation or any order of any Governmental Authority, (d) violate or result in a default under any indenture, agreement or other instrument binding upon the Borrower or any of its Restricted
Subsidiaries or its assets, or give rise to a right thereunder to require any payment to be made by the Borrower or any of its Restricted Subsidiaries, and (e) result in the creation or imposition of any Lien on any asset of the Borrower or any of
its Restricted Subsidiaries. Neither the Borrower nor any Restricted Subsidiary is in default and no event exists which with the giving of notice or lapse of time would constitute a default under any agreement evidencing or in respect of any of its
Material Indebtedness. 
  

 41

 (a) The Borrower has heretofore furnished to the Lenders its
consolidated balance sheet and statements of income, stockholders’ equity and cash flows as of and for the fiscal year ended December 31, 2004, reported on by KPMG, LLP, independent public accountants. Such financial statements present fairly,
in all material respects, the financial position and results of operations and cash flows of the Borrower and its consolidated Subsidiaries as of such date and for such period in accordance with GAAP.

interests in, all its real and personal property material to its business, except for (a) Liens permitted by Section 6.02 and (b) any failure, defect or other matter that could not, in the aggregate, reasonably be expected to have a Material Adverse
Effect. Each of the Borrower and its Restricted Subsidiaries owns, or is licensed to use, all trademarks, tradenames, copyrights, patents and other intellectual property material to its business, and the use thereof by the Borrower and such
Restricted Subsidiaries does not infringe upon the rights of any other Person, except for any such infringements that, individually or in the aggregate, could not reasonably be expected to result in a Material Adverse Effect. Each of the Borrower
and its Restricted Subsidiaries own or have valid licenses or other rights to use all databases, geological data, geophysical data, engineering data, seismic data, maps, interpretations and other technical information used in their businesses as
presently conducted, subject to the limitations contained in the agreements governing the use of the same, which limitations are customary for companies engaged in the business of the exploration and production of Hydrocarbons, with such exceptions
as could not reasonably be expected to have a Material Adverse Effect. 
  
 Section 3.06 Litigation and Environmental Matters. 
  
 (a) There are no actions, suits or proceedings by or before any arbitrator or Governmental Authority pending against or, to the knowledge of the Borrower, threatened against or affecting the Borrower or any of its
Subsidiaries that could reasonably be expected, individually or in the aggregate, to result in a Material Adverse Effect (other than the Disclosed Matters) or, as of the Effective Date, that involve this Agreement or the Transactions. 
  
 (b) Except for the Disclosed Matters and except with respect
to any other matters that, individually or in the aggregate, could not reasonably be expected to result in a Material Adverse Effect, neither the Borrower nor any of its Subsidiaries (i) has failed to comply with any Environmental Law or to obtain,
maintain or comply with any permit, license or other approval required under any Environmental Law, (ii) has become subject to any Environmental Liability, (iii) has received notice of any claim with respect to any Environmental Liability or (iv)

 Section 3.07 Compliance with Laws. Each of the Borrower and its Restricted Subsidiaries is in compliance with all laws, regulations and
orders of any Governmental Authority applicable to it or its property and all indentures, agreements and other instruments binding upon it or its property, except where the failure to do so, individually or in the aggregate, could not reasonably be
expected to result in a Material Adverse Effect. No Default has occurred and is continuing.

has fulfilled its obligations under the minimum funding standards of ERISA and the Code with respect to each Plan and is in compliance in all material respects with the presently applicable provisions of ERISA and the Code with respect to each Plan.
Neither the Borrower nor any ERISA Affiliate has (a) sought a waiver of the minimum funding standard under Section 412 of the Code in respect of any Plan, (b) failed to make any contribution or payment to any Plan or Multiemployer Plan, or made any
amendment to any Plan that has resulted or could result in the imposition of a Lien or the posting of a bond or other security under ERISA or the Code, or (c) incurred any liability under Title IV of ERISA other than a liability to the PBGC for
premiums under Section 4007 of ERISA that are not past due. 
  
 Section 3.11 Disclosure. The information furnished by or on behalf of the Borrower to the Administrative Agent, either of the Co-Arrangers or any Lender in connection with the negotiation of this Agreement or any Loan Document
or delivered hereunder (as modified or supplemented by other information so furnished), is complete and correct in all material respects and does not or will not, when furnished, contain any untrue statement of a material fact or omit to state a
material fact necessary in order to make the statements contained therein not misleading in light of the circumstances under which such statements are made; provided that, with respect to projected financial information, the Borrower represents only

material to the conduct of its business except for any failure to maintain, preserve or qualify that could not reasonably be expected to have a Material Adverse Effect; provided that the foregoing shall not prohibit (i) any merger, consolidation,
liquidation or dissolution permitted under Section 6.03 or (ii) a termination of such existence, good standing, rights licenses, permits, privileges and franchises of any Restricted Subsidiary if Borrower determines in good faith that such
termination is in the best interest of Borrower and could not reasonably be expected to have a Material Adverse Effect. 
  
 Section 5.04 Payment of Obligations. The Borrower will, and will cause each of its Subsidiaries to, pay its obligations, including Tax

with financially sound and reputable insurance companies, insurance in such amounts and against such risks as are customarily maintained by companies engaged in the same or similar businesses operating in the same or similar locations. 

 
 Section 5.06 Books and Records; Inspection Rights. The

 Section 5.07 Compliance with Laws. The Borrower will, and will cause each of its Subsidiaries to, comply with
all laws, rules, regulations and orders of any Governmental Authority applicable to it or its property, except where the failure to do so, individually or in the aggregate, could not reasonably be expected to result in a Material Adverse Effect.

the Board, including Regulations T, U and X. 
  
 Section 5.09

Affiliate.

 ARTICLE VIII 
 THE ADMINISTRATIVE AGENT 
  
 Section 8.01 Administrative Agent. Each of the Lenders and the
Issuing Banks hereby irrevocably appoints the Administrative Agent as its agent and authorizes the Administrative Agent to take such actions on its behalf and to exercise such powers as are delegated to the Administrative Agent by the terms hereof,
together with such actions and powers as are reasonably incidental thereto. 
  
 The bank serving as the Administrative Agent hereunder shall have the same rights and powers in its capacity as a Lender as any other Lender and may exercise the same as though it were not the Administrative Agent,
and such bank and its Affiliates may accept deposits from, lend money to and generally engage in any kind of business with the Borrower or any Subsidiary or other Affiliate thereof as if it were not the Administrative Agent hereunder. 
  
 The Administrative Agent shall not have any duties or obligations except
those expressly set forth herein. Without limiting the generality of the foregoing, (a) the Administrative Agent shall not be subject to any fiduciary or other implied duties, regardless of whether a Default has occurred and is continuing, (b) the
Administrative Agent shall not have any duty to take any discretionary action or exercise any discretionary powers, except discretionary rights and powers expressly contemplated hereby that the Administrative Agent is required to exercise in writing
as directed by the Required Lenders (or such other number or percentage of the Lenders as shall be necessary under the circumstances as provided in Section 9.02), and (c) except as expressly set forth herein, the Administrative Agent shall not have
any duty to disclose, and shall not be liable for the failure to disclose, any information relating to the Borrower or any of its Subsidiaries that is communicated to or obtained by the bank serving as Administrative Agent or any of its Affiliates
in any capacity. The Administrative Agent shall not be liable for any action taken or not taken by it with the consent or at the request of the Required Lenders (or such other number or percentage of the Lenders as shall be necessary under the
circumstances as provided in Section 9.02) or in the absence of its own gross negligence or willful misconduct. The Administrative Agent shall be deemed not to have knowledge of any Default unless and until written notice thereof is given to the
Administrative Agent by the Borrower or a Lender, and the Administrative Agent shall not be responsible for or have any duty to ascertain 

  

 54 

 
or inquire into (i) any statement, warranty or representation made in or in connection with this Agreement, (ii) the contents of any certificate, report or
other document delivered hereunder or in connection herewith, (iii) the performance or observance of any of the covenants, agreements or other terms or conditions set forth herein, (iv) the validity, enforceability, effectiveness or genuineness of
this Agreement or any other agreement, instrument or document, or (v) the satisfaction of any condition set forth in Article IV or elsewhere herein, other than to confirm receipt of items expressly required to be delivered to the Administrative
Agent. 
  
 The Administrative Agent shall be entitled to rely
upon, and shall not incur any liability for relying upon, any notice, request, certificate, consent, statement, instrument, document or other writing believed by it to be genuine and to have been signed or sent by the proper Person. The
Administrative Agent also may rely upon any statement made to it orally or by telephone and believed by it to be made by the proper Person, and shall not incur any liability for relying thereon. The Administrative Agent may consult with legal
counsel (who may be counsel for the Borrower), independent accountants and other experts selected by it, and shall not be liable for any action taken or not taken by it in accordance with the advice of any such counsel, accountants or experts.

  
 The Administrative Agent may perform any and all its duties
and exercise its rights and powers by or through any one or more sub-agents appointed by the Administrative Agent. The Administrative Agent and any such sub-agent may perform any and all its duties and exercise its rights and powers through their
respective Related Parties. The exculpatory provisions of the preceding paragraphs shall apply to any such sub-agent and to the Related Parties of the Administrative Agent and any such sub-agent, and shall apply to their respective activities in
connection with the syndication of the credit facilities provided for herein as well as activities as Administrative Agent. 
  
 Subject to the appointment and acceptance of a successor Administrative Agent as provided in this paragraph, the Administrative Agent may resign at any
time by notifying the Lenders, the Issuing Banks and the Borrower or be removed for cause by the Required Lenders. Upon any such resignation or removal, the Required Lenders shall have the right, in consultation with the Borrower, to appoint a
successor. If no successor shall have been so appointed by the Required Lenders and shall have accepted such appointment within 30 days after the retiring Administrative Agent gives notice of its resignation or is removed, then the retiring
Administrative Agent may, on behalf of the Lenders and the Issuing Banks, appoint a successor Administrative Agent. Upon the acceptance of its appointment as Administrative Agent hereunder by a successor, such successor shall succeed to and become
vested with all the rights, powers, privileges and duties of the retiring Administrative Agent, and the retiring Administrative Agent shall be discharged from its duties and obligations hereunder. The fees payable by the Borrower to a successor
Administrative Agent shall be the same as those payable to its predecessor unless otherwise agreed between the Borrower and such successor. After the Administrative Agent’s resignation hereunder, the provisions of this Article and Section 9.03
shall continue in effect for the benefit of such retiring Administrative Agent, its sub-agents and their respective Related Parties in respect of any actions taken or omitted to be taken by any of them while it was acting as Administrative Agent.

  

 55 

 Each Lender acknowledges that it has, independently and without reliance upon the Administrative Agent or
any other Lender and based on such documents and information as it has deemed appropriate, made its own credit analysis and decision to enter into this Agreement. Each Lender also acknowledges that it will, independently and without reliance upon
the Administrative Agent or any other Lender and based on such documents and information as it shall from time to time deem appropriate, continue to make its own decisions in taking or not taking action under or based upon this Agreement, any
related agreement or any document furnished hereunder or thereunder. 
  
 Section 8.02 The Co-Arrangers, Joint Bookrunners, Co-Syndication Agents and Co-Documentation Agents. The Co-Arrangers, Joint Bookrunners, Co-Syndication Agents and Co-Documentation Agents shall have no duties, responsibilities
or liabilities under this Agreement and the other Loan Documents other than their duties, responsibilities and liabilities in their capacity as Lenders (or Issuing Bank, if applicable) hereunder.

the case of any Lender, to the Administrative Agent and the Borrower. All notices and other communications given to any party hereto in accordance with the provisions of this Agreement shall be deemed to have been given on the date of receipt.

  
 Section 9.02 Waivers; Amendments. 
  
 (a) No failure or delay by the Administrative Agent, the
Issuing Banks or any Lender in exercising any right or power hereunder shall operate as a waiver thereof, nor shall any single or partial exercise of any such right or power, or any abandonment or discontinuance of steps to enforce such a right or
power, preclude any other or further exercise thereof or the exercise of any other right or power. The rights and remedies of the Administrative Agent, the Issuing Banks and the Lenders hereunder are cumulative and are not exclusive of any rights or
remedies that they would otherwise have. No waiver of any provision of this Agreement or consent to any departure by the Borrower therefrom shall in any event be effective unless the same shall be permitted by paragraph (b) of this Section, and then
such waiver or consent shall be effective only in the specific instance and for the purpose for which given. Without limiting the generality of the foregoing, the making of a Loan or issuance of a Letter of Credit shall not be construed as a waiver
of any Default, regardless of whether the Administrative Agent, any Lender or any Issuing Bank may have had notice or knowledge of such Default at the time. 
  
 (b) Neither this Agreement, any provision hereof, nor any provisions of the Subsidiary Guaranties may be waived, amended or modified
except pursuant to an agreement or agreements in writing entered into by the Borrower and the Required Lenders or by the Borrower and the Administrative Agent with the consent of the Required Lenders; provided that no such agreement shall (i)
increase or extend the Commitment of any Lender without the written consent of such Lender, (ii) reduce the principal amount of any Loan or LC Disbursement or reduce the rate of interest thereon, or reduce any fees payable hereunder, without the
written consent of each Lender affected thereby, (iii) postpone the scheduled date of payment of the principal amount of any Loan or LC Disbursement, or any interest thereon, or any fees payable hereunder, or reduce the amount of, waive or excuse
any such payment, or postpone the scheduled date of expiration of any Commitment, without the written consent of each Lender affected thereby, (iv) change Section 2.09 or Section 2.18(b) or (c) in a manner that would alter the pro rata treatment of
Lenders or pro rata sharing of payments required thereby, without the written consent of each Lender, (v) release any Subsidiary Guarantor from its obligations under this Agreement or its Subsidiary Guarantee unless the Borrower and its Subsidiaries
no longer own any of the Equity Interests of such Subsidiary Guarantor, or (vi) waive or amend any provision of Section 2.05 or change any of the provisions of this Section or the definition of “Required Lenders” or any other provision
hereof specifying the number or percentage of Lenders required to waive, amend or modify any rights hereunder or make any determination or grant any consent hereunder, without the written consent of each Lender; provided further that 

  

 57 

 
no such agreement shall amend, modify or otherwise affect the rights or duties of any Agent or the Issuing Banks hereunder without the prior written consent
of such Agent or the Issuing Banks, as the case may be. 
  
 Section 9.03 Expenses; Indemnity; Damage Waiver. 
  
 (a) The Borrower shall pay (i) all reasonable out-of-pocket expenses incurred by the Administrative Agent and the Co-Arranger and their Affiliates, including the reasonable fees, charges and disbursements of counsel

provisions hereof (whether or not the transactions contemplated hereby or thereby shall be consummated), (ii) all reasonable out-of-pocket expenses incurred by the Issuing Banks in connection with the issuance, amendment, renewal or extension of any
Letter of Credit or any demand for payment thereunder and (iii) all reasonable out-of-pocket expenses incurred by the Administrative Agent, the Issuing Banks or any Lender, including the reasonable fees, charges and disbursements of any counsel for

the Loans made or Letters of Credit issued hereunder, including all such reasonable out-of-pocket expenses incurred during any workout, restructuring or negotiations in respect of such Loans or Letters of Credit. 
  
 (b) THE BORROWER SHALL INDEMNIFY THE ADMINISTRATIVE AGENT,
EACH ISSUING BANK, EACH LENDER AND EACH RELATED PARTY OF ANY OF THE FOREGOING PERSONS (EACH SUCH PERSON BEING CALLED AN “INDEMNITEE”) AGAINST, AND HOLD EACH INDEMNITEE HARMLESS FROM, ANY AND ALL LOSSES, CLAIMS, DAMAGES, LIABILITIES
AND RELATED EXPENSES, INCLUDING THE REASONABLE FEES, CHARGES AND DISBURSEMENTS OF ANY COUNSEL FOR ANY INDEMNITEE, INCURRED BY OR ASSERTED AGAINST ANY INDEMNITEE ARISING OUT OF, IN CONNECTION WITH, OR AS A RESULT OF (i) THE EXECUTION OR DELIVERY OF
THIS AGREEMENT OR ANY AGREEMENT OR INSTRUMENT CONTEMPLATED HEREBY, THE PERFORMANCE BY THE PARTIES HERETO OF THEIR RESPECTIVE OBLIGATIONS HEREUNDER OR THE CONSUMMATION OF THE TRANSACTIONS OR ANY OTHER TRANSACTIONS CONTEMPLATED HEREBY, (ii) ANY LOAN
OR LETTER OF CREDIT OR THE USE OF THE PROCEEDS THEREFROM (INCLUDING ANY REFUSAL BY AN ISSUING BANK TO HONOR OR DEMAND FOR PAYMENT UNDER A LETTER OF CREDIT IF THE DOCUMENTS PRESENTED IN CONNECTION WITH SUCH DEMAND DO NOT STRICTLY COMPLY WITH THE
TERMS OF SUCH LETTER OF CREDIT), (iii) ANY ACTUAL OR ALLEGED PRESENCE OR RELEASE OF HAZARDOUS MATERIALS ON OR FROM ANY PROPERTY OWNED OR OPERATED BY THE BORROWER OR ANY OF ITS SUBSIDIARIES, OR ANY ENVIRONMENTAL LIABILITY RELATED IN ANY WAY TO THE

ACTIVE OR PASSIVE, WHETHER AN AFFIRMATIVE ACT OR AN OMISSION, INCLUDING WITHOUT LIMITATION, ALL TYPES OF NEGLIGENT CONDUCT IDENTIFIED IN THE RESTATEMENT (SECOND) OF TORTS OF ONE OR MORE OF THE INDEMNITEES OR BY REASON OF STRICT LIABILITY IMPOSED
WITHOUT FAULT ON ANY ONE OR MORE OF THE INDEMNITEES INCLUDING THE ORDINARY NEGLIGENCE OF SUCH INDEMNITEE; PROVIDED THAT SUCH INDEMNITY SHALL NOT, AS TO ANY INDEMNITEE, BE AVAILABLE TO THE EXTENT THAT SUCH LOSSES, CLAIMS, DAMAGES, LIABILITIES
OR RELATED EXPENSES ARE DETERMINED BY A COURT OF COMPETENT JURISDICTION BY FINAL AND NONAPPEALABLE JUDGMENT TO HAVE RESULTED FROM THE GROSS NEGLIGENCE OR WILLFUL MISCONDUCT OF SUCH INDEMNITEE. 
  
 (c) To the extent that the Borrower fails to pay any amount
required to be paid by it to the Administrative Agent or an Issuing Bank under paragraph (a) or (b) of this Section, each Lender severally agrees to pay to the Administrative Agent or such Issuing Bank, as the case may be, such Lender’s
Applicable Percentage (determined as of the time that the applicable unreimbursed expense or indemnity payment is sought) of such unpaid amount; provided that the unreimbursed expense or indemnified loss, claim, damage, liability or related expense,
as the case may be, was incurred by or asserted against the Administrative Agent or such Issuing Bank in its capacity as such. 
  
 (d) To the extent permitted by applicable law, the Borrower shall not assert, and hereby waives, any claim against any Indemnitee, on any
theory of liability, for special, indirect, consequential or punitive damages (as opposed to direct or actual damages) arising out of, in connection with, or as a result of, this Agreement or any agreement or instrument contemplated hereby, the
Transactions, any Loan or Letter of Credit or the use of the proceeds thereof. 
  
 (e) All amounts due under this Section shall be payable not later than 30 days after written demand therefor.

and inure to the benefit of the parties hereto and their respective successors and assigns permitted hereby (including any Affiliates of an Issuing Bank that issue any Letters of Credit), except that (i) the Borrower may not assign or otherwise
transfer any of its rights or obligations hereunder without the prior written consent of each Lender (and any attempted assignment or transfer by the Borrower without such consent shall be null and void) and (ii) no Lender may assign or otherwise
transfer its rights or obligations hereunder except in accordance with this Section. Nothing in this Agreement, expressed or implied, shall be construed to confer upon any Person (other than the parties hereto, their respective successors and
assigns permitted hereby (including any Affiliates of an Issuing Bank that issue any Letters of Credit), Participants (to the extent provided in paragraph (c) of this Section) and, to the extent expressly contemplated hereby, the 

  

 59 

 
Related Parties of each of the Administrative Agent, the Issuing Banks and the Lenders) any legal or equitable right, remedy or claim under or by reason of
this Agreement. 
  
 (b) (i) Subject to the
conditions set forth in paragraph (b)(ii) below, any Lender may assign to one or more assignees all or a portion of its rights and obligations under this Agreement (including all or a portion of its Commitment and the Loans at the time owing to it)

 (A) the Borrower, provided that no consent of the Borrower shall be required for an assignment to a Lender, an Affiliate of a Lender, an
Approved Fund or, if an Event of Default has occurred and is continuing, any other assignee; and 
  
 (B) the Administrative Agent and each Issuing Bank, provided that no consent of the Administrative Agent shall be required for an
assignment of any Commitment to an assignee that is a Lender with a Commitment immediately prior to giving effect to such assignment, an Affiliate of such a Lender or an Approved Fund. 
  
 (ii) Assignments shall be subject to the following additional conditions: 
  
 (A) except in the case of an assignment to a Lender or an
Affiliate of a Lender or an assignment of the entire remaining amount of the assigning Lender’s Commitment or Loans, the amount of the Commitment or Loans of the assigning Lender subject to each such assignment (determined as of the date the
Assignment and Assumption with respect to such assignment is delivered to the Administrative Agent) shall not be less than $10,000,000 unless each of the Borrower and the Administrative Agent otherwise consent, such consent not to be unreasonably
withheld, provided that no such consent of the Borrower shall be required if an Event of Default has occurred and is continuing; 
  
 (B) each partial assignment shall be made as an assignment of a proportionate part of all the assigning Lender’s rights and
obligations under this Agreement; 
  
 (C) the
parties to each assignment shall execute and deliver to the Administrative Agent an Assignment and Assumption, together with a processing and recordation fee of $3,500; and 
  
 (D) the assignee, if it shall not be a Lender, shall deliver to the Administrative Agent an Administrative
Questionnaire and comply with the requirements of Section 2.17(e). 
  
 For the purposes of this Section 9.04(b), the term “Approved Fund” has the following meaning: 
  
 “Approved Fund” means any Person (other than a natural person) that is engaged in making, purchasing, holding or investing in bank loans
and similar extensions of credit in the ordinary course of its business and that is administered or managed by (a) a Lender, (b) an Affiliate of a Lender or (c) an entity or an Affiliate of an entity that administers or manages a Lender. 

 

 60 

 (iii) Subject to acceptance and recording thereof pursuant to paragraph (b)(iv) of this
Section, from and after the effective date specified in each Assignment and Assumption the assignee thereunder shall be a party hereto and, to the extent of the interest assigned by such Assignment and Assumption, have the rights and obligations of
a Lender under this Agreement, and the assigning Lender thereunder shall, to the extent of the interest assigned by such Assignment and Assumption, be released from its obligations under this Agreement (and, in the case of an Assignment and
Assumption covering all of the assigning Lender’s rights and obligations under this Agreement, such Lender shall cease to be a party hereto but shall continue to be entitled to the benefits of Sections 2.15, 2.16, 2.17 and 9.03). Any assignment
or transfer by a Lender of rights or obligations under this Agreement that does not comply with this Section 9.04 shall be treated for purposes of this Agreement as a sale by such Lender of a participation in such rights and obligations in
accordance with paragraph (c) of this Section. 
  
 (iv) The Administrative Agent, acting for this purpose as an agent of the Borrower, shall maintain at one of its offices a copy of each Assignment and Assumption delivered to it and a register for the recordation of the names and addresses
of the Lenders, and the Commitment of, and principal amount of the Loans and LC Disbursements owing to, each Lender pursuant to the terms hereof from time to time (the “Register”). The entries in the Register shall be conclusive,
and the Borrower, the Administrative Agent, the Issuing Banks, and the Lenders may treat each Person whose name is recorded in the Register pursuant to the terms hereof as a Lender hereunder for all purposes of this Agreement, notwithstanding notice
to the contrary. The Register shall be available for inspection by the Borrower, the Issuing Banks and any Lender, at any reasonable time and from time to time upon reasonable prior notice. 
  
 (v) Upon its receipt of a duly completed Assignment and
Assumption executed by an assigning Lender and an assignee, the assignee’s completed Administrative Questionnaire (unless the assignee shall already be a Lender hereunder), the processing and recordation fee referred to in paragraph (b) of this
Section and any written consent to such assignment required by paragraph (b) of this Section, the Administrative Agent shall accept such Assignment and Assumption and record the information contained therein in the Register. No assignment shall be
effective for purposes of this Agreement unless it has been recorded in the Register as provided in this paragraph. 
  
 (c) (i) Any Lender may, without the consent of the Borrower, the Administrative Agent or the Issuing Banks, sell participations to one or
more banks or other entities (a “Participant”) in all or a portion of such Lender’s rights and obligations under this Agreement (including all or a portion of its Commitment and the Loans owing to it); provided that (A) such
Lender’s obligations under this Agreement shall remain unchanged, (B) such Lender shall remain solely responsible to the other parties hereto for the performance of such obligations and (C) the Borrower, the Administrative Agent, the Issuing
Banks and the other Lenders shall continue to deal solely and directly with such Lender in connection with such Lender’s rights and obligations under this Agreement. Any agreement or instrument pursuant to which a Lender sells such a
participation shall provide that such Lender shall retain the sole right to enforce this Agreement and to approve any amendment, modification or waiver of any provision of this Agreement; provided that such agreement or instrument may provide that
such Lender will not, without the consent of the Participant, agree to any amendment, modification or 

  

 61 

 
waiver described in the first proviso to Section 9.02(b) that affects such Participant. Subject to paragraph (c)(ii) of this Section, the Borrower agrees
that each Participant shall be entitled to the benefits of Sections 2.15, 2.16 and 2.17 to the same extent as if it were a Lender and had acquired its interest by assignment pursuant to paragraph (b) of this Section. 
  
 (ii) A Participant shall not be entitled to receive any
greater payment under Section 2.15 or Section 2.17 than the applicable Lender would have been entitled to receive with respect to the participation sold to such Participant, unless the sale of the participation to such Participant is made with the
Borrower’s prior written consent. 
  
 (d)
Any Lender may at any time pledge or assign a security interest in all or any portion of its rights under this Agreement to secure obligations of such Lender, including without limitation any pledge or assignment to secure obligations to a Federal
Reserve Bank, and this Section shall not apply to any such pledge or assignment of a security interest; provided that no such pledge or assignment of a security interest shall release a Lender from any of its obligations hereunder or substitute any
such pledgee or assignee for such Lender as a party hereto. 
  
 Section 9.05 Survival. All covenants, agreements, representations and warranties made by the Borrower herein and in the certificates or other instruments delivered in connection with or pursuant to this Agreement shall be
considered to have been relied upon by the other parties hereto and shall survive the execution and delivery of this Agreement and the making of any Loans and issuance of any Letters of Credit, regardless of any investigation made by any such other
party or on its behalf and notwithstanding that the Administrative Agent, any Issuing Bank or any Lender may have had notice or knowledge of any Default or incorrect representation or warranty at the time any credit is extended hereunder, and shall
continue in full force and effect as long as the principal of or any accrued interest on any Loan or any fee or any other amount payable under this Agreement is outstanding and unpaid or any Letter of Credit is outstanding and so long as the
Commitments have not expired or terminated. The provisions of Sections 2.15, 2.16, 2.17 and 9.03 and Article VIII shall survive and remain in full force and effect regardless of the consummation of the transactions contemplated hereby, the repayment
of the Loans, the expiration or termination of the Letters of Credit and the Commitments or the termination of this Agreement or any provision hereof. 
  
 Section 9.06 Counterparts; Integration; Effectiveness. This Agreement may be executed in counterparts (and by different parties hereto on
different counterparts), each of which shall constitute an original, but all of which when taken together shall constitute a single contract. This Agreement and any separate letter agreements with respect to fees payable to the Administrative Agent
constitute the entire contract among the parties relating to the subject matter hereof and supersede any and all previous agreements and understandings, oral or written, relating to the subject matter hereof. Except as provided in Section 4.01, this
Agreement shall become effective when it shall have been executed by the Administrative Agent and when the Administrative Agent shall have received counterparts hereof which, when taken together, bear the signatures of each of the other parties
hereto, and thereafter shall be binding upon and inure to the benefit of the parties hereto and their respective successors and assigns. Delivery of an executed counterpart of a signature page of this Agreement by telecopy shall be effective as
delivery of a manually executed counterpart of this Agreement. 
  

 62 

 Section 9.07 Severability. Any provision of this Agreement held to be invalid, illegal or
unenforceable in any jurisdiction shall, as to such jurisdiction, be ineffective to the extent of such invalidity, illegality or unenforceability without affecting the validity, legality and enforceability of the remaining provisions hereof; and the
invalidity of a particular provision in a particular jurisdiction shall not invalidate such provision in any other jurisdiction. 
  
 Section 9.08 Governing Law; Jurisdiction; Consent to Service of Process. 
  
 (a) THIS AGREEMENT AND THE NOTES SHALL BE GOVERNED BY, AND CONSTRUED IN ACCORDANCE WITH, THE LAWS OF THE
STATE OF TEXAS EXCEPT TO THE EXTENT THAT UNITED STATES FEDERAL LAW PERMITS ANY LENDER TO CONTRACT FOR, CHARGE, RECEIVE, RESERVE OR TAKE INTEREST AT THE RATE ALLOWED BY THE LAWS OF THE STATE WHERE SUCH LENDER IS LOCATED. CHAPTER 346 OF THE TEXAS
FINANCE CODE (WHICH REGULATES CERTAIN REVOLVING CREDIT LOAN ACCOUNTS AND REVOLVING TRI-PARTY ACCOUNTS) SHALL NOT APPLY TO THIS AGREEMENT. 
  
 (b) ANY LEGAL ACTION OR PROCEEDING WITH RESPECT TO THE LOAN DOCUMENTS MAY BE BROUGHT IN THE COURTS OF THE STATE OF TEXAS OR OF THE UNITED
STATES OF AMERICA SITUATED IN TARRANT COUNTY OR HARRIS COUNTY OF THE STATE OF TEXAS, AND, BY EXECUTION AND DELIVERY OF THIS AGREEMENT, EACH PARTY HEREBY ACCEPTS FOR ITSELF AND (TO THE EXTENT PERMITTED BY LAW) IN RESPECT OF ITS PROPERTY, GENERALLY
AND UNCONDITIONALLY, THE JURISDICTION OF THE AFORESAID COURTS. EACH PARTY HEREBY IRREVOCABLY WAIVES ANY OBJECTION, INCLUDING, WITHOUT LIMITATION, ANY OBJECTION TO THE LAYING OF VENUE OR BASED ON THE GROUNDS OF FORUM NON CONVENIENS, WHICH IT MAY NOW
OR HEREAFTER HAVE TO THE BRINGING OF ANY SUCH ACTION OR PROCEEDING IN SUCH RESPECTIVE JURISDICTIONS. THIS SUBMISSION TO JURISDICTION IS NON-EXCLUSIVE AND DOES NOT PRECLUDE A PARTY FROM OBTAINING JURISDICTION OVER ANOTHER PARTY IN ANY COURT OTHERWISE
HAVING JURISDICTION. 
  
 (c) EACH PARTY
IRREVOCABLY CONSENTS TO THE SERVICE OF PROCESS OF ANY OF THE AFOREMENTIONED COURTS IN ANY SUCH ACTION OR PROCEEDING BY THE MAILING OF COPIES THEREOF BY REGISTERED OR CERTIFIED MAIL, POSTAGE PREPAID, TO IT AT THE ADDRESS SPECIFIED IN SECTION 9.01 OR
SUCH OTHER ADDRESS AS IS SPECIFIED PURSUANT TO SECTION 9.01 (OR ITS ASSIGNMENT AND ASSUMPTION), SUCH SERVICE TO BECOME EFFECTIVE THIRTY (30) DAYS AFTER SUCH MAILING. NOTHING HEREIN SHALL AFFECT THE RIGHT OF A PARTY OR ANY HOLDER OF A NOTE TO SERVE
PROCESS IN ANY OTHER MANNER PERMITTED BY LAW OR TO COMMENCE LEGAL PROCEEDINGS OR OTHERWISE PROCEED AGAINST ANOTHER PARTY IN ANY OTHER JURISDICTION. 
  
 Section 9.09 WAIVER OF JURY TRIAL. EACH PARTY HEREBY (i) IRREVOCABLY AND UNCONDITIONALLY WAIVES, TO THE FULLEST EXTENT PERMITTED BY LAW,
TRIAL BY JURY IN ANY LEGAL ACTION OR PROCEEDING 

  

 63 

 
RELATING TO THIS AGREEMENT OR ANY OTHER DOCUMENT RELATED TO THIS AGREEMENT AND FOR ANY COUNTERCLAIM THEREIN; (ii) IRREVOCABLY WAIVES, TO THE MAXIMUM EXTENT
NOT PROHIBITED BY LAW, ANY RIGHT IT MAY HAVE TO CLAIM OR RECOVER IN ANY SUCH LITIGATION ANY SPECIAL, EXEMPLARY, PUNITIVE OR CONSEQUENTIAL DAMAGES, OR DAMAGES OTHER THAN, OR IN ADDITION TO, ACTUAL DAMAGES; (iii) CERTIFIES THAT NO PARTY HERETO NOR ANY
REPRESENTATIVE OR AGENT OR COUNSEL FOR ANY PARTY HERETO HAS REPRESENTED, EXPRESSLY OR OTHERWISE, OR IMPLIED THAT SUCH PARTY WOULD NOT, IN THE EVENT OF LITIGATION, SEEK TO ENFORCE THE FOREGOING WAIVERS, AND (iv) ACKNOWLEDGES THAT IT HAS BEEN INDUCED
TO ENTER INTO THIS AGREEMENT, THE LOAN DOCUMENTS AND THE TRANSACTIONS CONTEMPLATED HEREBY AND THEREBY BY, AMONG OTHER THINGS, THE MUTUAL WAIVERS AND CERTIFICATIONS CONTAINED IN THIS SECTION 9.09. 
  
 Section 9.10 Headings. Article and Section headings and the
Table of Contents used herein are for convenience of reference only, are not part of this Agreement and shall not affect the construction of, or be taken into consideration in interpreting, this Agreement. 
  
 Section 9.11 Confidentiality. Each of the Administrative Agent,
the Issuing Banks and the Lenders agrees to maintain the confidentiality of the Information (as defined below), except that Information may be disclosed (a) to its and its Affiliates’ directors, officers, employees and agents, including
accountants and legal counsel (it being understood that the Persons to whom such disclosure is made will be informed of the confidential nature of such Information and instructed to keep such Information confidential), (b) to the extent requested by
any regulatory authority or any self-regulatory body claiming to have authority, (c) to the extent required by applicable laws or regulations or by any subpoena or similar legal process or authority, (d) to any other party to this Agreement, (e) in
connection with the exercise of any remedies hereunder or any suit, action or proceeding relating to this Agreement or the enforcement of rights hereunder, (f) to (i) any assignee of or Participant in, or any prospective assignee of or Participant
in, any of its rights or obligations under this Agreement, (ii) any actual or prospective counterparty (or its advisors) to any swap or derivative transaction relating to the Borrower and its obligations, or (iii) to its legal, tax and accounting
advisors, provided that the Persons to whom such disclosure is made will be informed of the confidential nature of such Information and shall agree in writing to maintain the confidentiality thereof or, in the case of its legal, tax and accounting
advisors, instructed to keep such Information confidential, (g) with the consent of the Borrower or (h) to the extent such Information becomes publicly available other than as a result of a breach of this Section. For the purposes of this Section,
“Information” means all information received from the Borrower relating to the Borrower or its business, other than any such information that is available to the Administrative Agent, any Issuing Bank or any Lender on a nonconfidential
basis prior to disclosure by the Borrower. 
  
 Section
9.12 Interest Rate Limitation. It is the intention of the parties hereto that each Lender shall conform strictly to usury laws applicable to it. Accordingly, if the transactions contemplated hereby would be usurious as to any Lender under
laws applicable to it (including the laws of the United States of America and the State of Texas or any other jurisdiction whose laws may be mandatorily applicable to such Lender notwithstanding the other provisions of this 

  

 64 

 
Agreement), then, in that event, notwithstanding anything to the contrary in the Agreement or the Subsidiary Guaranties, it is agreed as follows: (i) the
aggregate of all consideration which constitutes interest under law applicable to any Lender that is contracted for, taken, reserved, charged or received by such Lender under the Agreement or the Subsidiary Guaranties shall under no circumstances
exceed the maximum amount allowed by such applicable law, and any excess shall be canceled automatically and if theretofore paid shall be credited by such Lender on the principal amount of the Indebtedness (or, to the extent that the principal
amount of the Indebtedness shall have been or would thereby be paid in full, refunded by such Lender to the Borrower); and (ii) in the event of any required or permitted prepayment, then such consideration that constitutes interest under law
applicable to any Lender may never include more than the maximum amount allowed by such applicable law, and excess interest, if any, provided for in this Agreement or otherwise shall be canceled automatically by such Lender as of the date of such
acceleration or prepayment and, if theretofore paid, shall be credited by such Lender on the principal amount of the Indebtedness (or, to the extent that the principal amount of the Indebtedness shall have been or would thereby be paid in full,
refunded by such Lender to the Borrower). All sums paid or agreed to be paid to any Lender for the use, forbearance or detention of sums due hereunder shall, to the extent permitted by law applicable to such Lender, be amortized, prorated, allocated
and spread throughout the stated term of the Loans until payment in full so that the rate or amount of interest on account of any Loans hereunder does not exceed the maximum amount allowed by such applicable law. If at any time and from time to time
(i) the amount of interest payable to any Lender on any date shall be computed at the Highest Lawful Rate applicable to such Lender pursuant to this Section 9.12 and (ii) in respect of any subsequent interest computation period the amount of
interest otherwise payable to such Lender would be less than the amount of interest payable to such Lender computed at the Highest Lawful Rate applicable to such Lender, then the amount of interest payable to such Lender in respect of such
subsequent interest computation period shall continue to be computed at the Highest Lawful Rate applicable to such Lender until the total amount of interest payable to such Lender shall equal the total amount of interest which would have been
payable to such Lender if the total amount of interest had been computed without giving effect to this Section 9.12. To the extent that Chapter 303 of the Texas Finance Code is relevant for the purpose of determining the Highest Lawful Rate
applicable to a Lender, such Lender elects to determine the applicable rate ceiling under such Chapter by the weekly ceiling from time to time in effect. Chapter 346 of the Texas Finance Code does not apply to the Borrower’s obligations
hereunder. 
  
 Section 9.13 Right of Setoff. If an
Event of Default shall have occurred and be continuing, each Lender and each of its Affiliates is hereby authorized at any time and from time to time, to the fullest extent permitted by law, to set off and apply any and all deposits (general or
special, time or demand, provisional or final) at any time held and other obligations at any time owing by such Lender or Affiliate to or for the credit or the account of any Obligor against any of and all the obligations of any Obligor now or
hereafter existing under this Agreement or any Loan Document held by such Lender, irrespective of whether or not such Lender shall have made any demand under this Agreement or any Loan Document and although such obligations may be unmatured. The
rights of each Lender under this Section are in addition to other rights and remedies (including other rights of setoff) which such Lender may have. 
  
 Section 9.14 USA Patriot Act Notice. Each Lender hereby notifies the Borrower that pursuant to the requirements of the USA Patriot Act
(Title III of Pub. L. 107-56 (signed into law 

  

 65 

 
October 26, 2001)) (the “Act”), it is required to obtain, verify and record information that identifies the Borrower, which information
includes the name and address of the Borrower and other information that will allow such Lender to identify the Borrower in accordance with the Act. 
  
 Section 9.15 EXCULPATION PROVISIONS. EACH OF THE PARTIES HERETO SPECIFICALLY AGREES THAT IT HAS A DUTY TO READ THIS AGREEMENT AND THE OTHER
LOAN DOCUMENTS AND AGREES THAT IT IS CHARGED WITH NOTICE AND KNOWLEDGE OF THE TERMS OF THIS AGREEMENT AND THE OTHER LOAN DOCUMENTS; THAT IT HAS IN FACT READ THIS AGREEMENT AND IS FULLY INFORMED AND HAS FULL NOTICE AND KNOWLEDGE OF THE TERMS,
CONDITIONS AND EFFECTS OF THIS AGREEMENT; THAT IT HAS BEEN REPRESENTED BY INDEPENDENT LEGAL COUNSEL OF ITS CHOICE THROUGHOUT THE NEGOTIATIONS PRECEDING ITS EXECUTION OF THIS AGREEMENT AND THE OTHER LOAN DOCUMENTS; AND HAS RECEIVED THE ADVICE OF ITS
ATTORNEY IN ENTERING INTO THIS AGREEMENT AND THE OTHER LOAN DOCUMENTS; AND THAT IT RECOGNIZES THAT CERTAIN OF THE TERMS OF THIS AGREEMENT AND THE OTHER LOAN DOCUMENTS RESULT IN ONE PARTY ASSUMING THE LIABILITY INHERENT IN SOME ASPECTS OF THE
TRANSACTION AND RELIEVING THE OTHER PARTY OF ITS RESPONSIBILITY FOR SUCH LIABILITY. EACH PARTY HERETO AGREES AND COVENANTS THAT IT WILL NOT CONTEST THE VALIDITY OR ENFORCEABILITY OF ANY EXCULPATORY PROVISION OF THIS AGREEMENT AND THE OTHER LOAN
DOCUMENTS ON THE BASIS THAT THE PARTY HAD NO NOTICE OR KNOWLEDGE OF SUCH PROVISION OR THAT THE PROVISION IS NOT “CONSPICUOUS.”

 DISCLOSED MATTERS 
  
 Litigation 
  
 On October 17,
1997, an action, styled United States of America ex rel. Grynberg v. Cross Timbers Oil Company, et al., was filed in the U.S. District Court for the Western District of Oklahoma by Jack J. Grynberg on behalf of the United States under the qui
tam provisions of the U.S. False Claims Act against the Company and certain of our subsidiaries. The plaintiff alleges that we underpaid royalties on natural gas produced from federal leases and lands owned by Native Americans in amounts in excess
of 20% as a result of mismeasuring the volume of natural gas, incorrectly analyzing its heating content and improperly valuing the natural gas during at least the past ten years. The plaintiff seeks treble damages for the unpaid royalties (with
interest, attorney fees and expenses), civil penalties between $5,000 and $10,000 for each violation of the U.S. False Claims Act, and an order for us to cease the allegedly improper measuring practices. This lawsuit against us and similar lawsuits
filed by Grynberg against more than 300 other companies have been consolidated in the United States District Court for Wyoming. In October 2002, the court granted a motion to dismiss Grynberg’s royalty valuation claims, and Grynberg’s
appeal of this decision was dismissed for lack of appellate jurisdiction in May 2003. The parties have completed discovery regarding whether the plaintiff has met the jurisdictional prerequisites for maintaining an action under the U.S. False Claims
Act. In June 2004, we joined with other defendants in filing a motion to dismiss, contending that the plaintiff has not satisfied the jurisdictional requirements to maintain this action. A hearing on this motion has been scheduled for March 2005.
While we are unable to predict the outcome of this case, we believe that the allegations of this lawsuit are without merit and intend to vigorously defend the action. Any potential liability from this claim cannot currently be reasonably estimated,
and no provision has been accrued in our financial statements. 
  
 In June 2001, we were served with a lawsuit styled Price, et al. v. Gas Pipelines, et al. The action was filed in the District Court of Stevens County, Kansas, against us and one of our subsidiaries, along with over 200 natural gas
transmission companies, producers, gatherers and processors of natural gas. The plaintiffs seek to represent a class of plaintiffs consisting of all similarly situated gas working interest owners, overriding royalty owners and royalty owners either
from whom the defendants had purchased natural gas or who received economic benefit from the sale of such gas since January 1, 1974. The allegations in the case are similar to those in the Grynberg case; however, the Price case
broadens the claims to cover all oil and gas leases (other than the federal and Native American leases that are the subject of the Grynberg case). The complaint alleges that the defendants have mismeasured both the volume and heating content
of natural gas delivered into their pipelines, resulting in underpayments to the plaintiffs. The plaintiffs assert a breach of contract claim, negligent or intentional misrepresentation, civil conspiracy, common carrier liability, conversion,
violation of a variety of Kansas statutes and other common law causes of action. The amount of damages was not specified in the complaint. In February 2002, we, along with one of our subsidiaries, were dismissed from the suit and another subsidiary
of the Company was added. A hearing was held in January 2003, and the court held that a class should not be certified. The plaintiffs’ counsel has filed an amended class 

  

 Schedule 3.06 
 Page 1 

 
action petition, which reduces the proposed class to only royalty owners, reduces the claims to mismeasurement of volume only, conspiracy, unjust enrichment
and accounting, and only applies to gas measured in Kansas, Colorado and Wyoming. The court has set an evidentiary hearing in April 2005 to determine whether the amended class should be certified. While we are unable to predict the outcome of this
case, we believe that the allegations of this lawsuit are without merit and intend to vigorously defend the action. Any potential liability from this claim cannot currently be reasonably estimated, and no provision has been accrued in our financial
statements. 
  
 On August 5, 2003, the Price plaintiffs
served one of our subsidiaries with a new original class action petition styled Price, et al. v. Gas Pipelines, et al. The action was filed in the District Court of Stevens County, Kansas, against natural gas pipeline owners and operators.
The plaintiffs seek to represent a class of plaintiffs consisting of all similarly situated gas royalty owners either from whom the defendants had purchased natural gas or measured natural gas since January 1, 1974 to the present. The new petition
alleges the same improper analysis of gas heating content that had previously been alleged in the Price case discussed above until it was removed from the case by the filing of the amended class action petition. In all other respects, the new
petition appears to be identical to the amended class action petition in that it has a proposed class of only royalty owners, alleges conspiracy, unjust enrichment and accounting, and only applies to gas measured in Kansas, Colorado and Wyoming. The
court has set an evidentiary hearing in April 2005 to determine whether the amended class should be certified. The amount of damages was not specified in the complaint. While we are unable to predict the outcome of this case, we believe that the
allegations of this lawsuit are without merit and intend to vigorously defend the action. Any potential liability from this claim cannot currently be reasonably estimated, and no provision has been accrued in our financial statements. 
  
 In September 2004, we were served with a lawsuit styled Burkett, et al. v.
J.M. Huber Corp. and XTO Energy Inc. The action was filed in the District Court of La Plata County, Colorado against us and J.M. Huber Corporation. The plaintiffs allege that the defendants have deducted in their calculation of royalty payments
expenses of compression, gathering, treatment, dehydration, or other costs to place the natural gas produced in a marketable condition at a marketable location. The plaintiffs seek to represent a class consisting of all lessors and their successors
in interest who own or have owned mineral interests located in La Plata County, Colorado and that are leased to or operated by Huber or us, except to the extent that the lessors or their successors have expressly authorized deduction of
post-production expenses from royalties. We acquired the interests of Huber in producing properties in La Plata County effective October 1, 2002, and have assumed the responsibility for certain liabilities of Huber prior to the effective date, which
may include liability for post-production deductions made by Huber. As of December 31, 2004, based on an evaluation of available information, we accrued a $3.1 million estimated liability for this claim in our consolidated financial statements. On
February 17, 2005, we agreed to a tentative settlement of approximately $5.1 million, resulting in an additional loss of approximately $2 million to be recorded in first quarter 2005.

 Exhibit B - 3 

 EXHIBIT C 
  

FORM OF 
  
 OPINION OF BORROWER’S COUNSEL 
  
 Borrower’s counsel’s opinion shall include the following opinions, subject to appropriate qualifications. 
  
 1. The Borrower is a corporation incorporated, validly existing and in good standing under the laws of the State of Delaware. The Borrower has the
requisite power and authority to execute, deliver and perform its obligations under the Credit Agreement, including the requisite power and authority to borrow Loans under the Credit Agreement and to issue any promissory notes issued thereunder. The
Credit Agreement has been authorized, executed and delivered by the Borrower. 
  
 2. The Borrower has taken all necessary action to authorize the execution and delivery of, and performance of its obligations under, the Credit Agreement, including the issuance of promissory notes as contemplated
thereby. The execution, delivery and performance by the Borrower of its obligations under the Credit Agreement will not result in a violation of its Certificate of Incorporation or By-laws. The execution, delivery and performance by the Borrower of
its obligations under the Credit Agreement will not (i) result in a violation of any Applicable Law (as herein defined) or require any consent, approval, license or authorization of or filing with any Governmental Authority pursuant to any
Applicable Law, (ii) result in a violation of or constitute a breach or default under any material agreement, instrument or judicial or regulatory order binding upon it or its properties, or (iii) result in the creation or imposition of any Lien on
any of its properties pursuant to any such material agreement, instrument or judicial or regulatory order. 
  
 As used herein, “Applicable Law” means: (i) the General Corporation Law of the State of Delaware and (ii) those laws, rules and regulations of
the State of Texas and of the United States of America which, in our experience, exercising customary professional diligence, are normally applicable to transactions of the type provided for in the Credit Agreement. 
  
 3. The Credit Agreement is, and each promissory note when issued thereunder
will be, the legal, valid and binding obligation of the Credit Agreement. 
  
 4. No authorization, consent, approval, license or exemption of, or filing or registration with, any Governmental Authority of the United States or the State of Texas or any Governmental Authority of the State of
Delaware in connection with any application of the General Corporation Law of the State of Delaware is necessary under any Applicable Law for either the due execution and delivery by the Borrower of the Credit Agreement or any promissory note issued
thereunder or the performance by the Borrower of its obligations under the Credit Agreement. 
  

 Exhibit C 

 5. Except as disclosed pursuant to the Credit Agreement, there are, to the best of our knowledge, no
actions, suits or proceedings pending or threatened against the Borrower or any of its Restricted Subsidiaries which involves the possibility of any judgment or liability against the Borrower or such Restricted Subsidiary which could reasonably be
expected to have a Material Adverse Effect.

“Lenders”) from time to time parties to the Amended and Restated 5-Year Revolving Credit Agreement dated as of April 1, 2005 (as amended, supplemented or otherwise modified from time to time, the “Credit
Agreement”), among XTO Energy Inc. (the “Borrower”), the Administrative Agent, the Issuing Banks, the Lenders and other agents party thereto. 
  
 RECITALS

 B. The Lenders have agreed to make such loans and extensions of credit
subject to the terms and conditions of the Credit Agreement. 
  
 C. It is a condition precedent to the obligation of the Lenders to make their respective extensions of credit to the Borrower under the Credit Agreement (or an ongoing covenant of the Borrower under the Credit Agreement) that the Subsidiary
Guarantor shall have executed and delivered this Subsidiary Guaranty to the Administrative Agent for the benefit of the Lenders. 
  
 D. The Subsidiary Guarantor has determined that it may reasonably benefit, either directly or indirectly, from executing and delivering this Subsidiary
Guaranty to the Administrative Agent for the benefit of the Lenders. 
  
 E. NOW, THEREFORE, in consideration of the premises herein and to induce the Administrative Agent and the Lenders to enter into the Credit Agreement and to induce the Lenders to make their respective extensions of credit to the Borrower
thereunder, the Subsidiary Guarantor hereby agrees with the Administrative Agent, for the benefit of the Lenders, as follows: 
  
 Section 1. Definitions. Unless otherwise defined herein, terms defined in the Credit Agreement and used herein have the meanings
given to them in the Credit Agreement. The following terms have the following meanings: 
  
 “Liabilities” means the collective reference to the payment and performance when due of all indebtedness, liabilities, obligations and undertakings of the Borrower (including, without limitation, all
Indebtedness) of every kind or description arising out of or outstanding under, advanced or issued pursuant to, or evidenced by, the Loan Documents, including, without limitation, the unpaid principal of and interest on the Loans and the LC Exposure
and all other 

  

 Exhibit D - 1 

 
obligations and liabilities of the Borrower (including, without limitation, interest accruing at the then applicable rate provided in the Credit Agreement
after the maturity of the Loans and LC Exposure and interest accruing after the filing of any petition in bankruptcy, or the commencement of any insolvency, reorganization or like proceeding, relating to the Borrower, whether or not a claim for
post-filing or post-petition interest is allowed in such proceeding) to the Guaranteed Creditors, whether direct or indirect, absolute or contingent, due or to become due, now existing or hereafter incurred, arising out of or outstanding under,
advanced or issued pursuant, or evidenced by, the Loan Documents, whether on account of principal, interest, premium, reimbursement obligations, payments in respect of an early termination date, fees, indemnities, costs, expenses or otherwise
(including, without limitation, all costs, fees and disbursements of counsel to the Guaranteed Creditors that are required to be paid by the Borrower pursuant to the terms of any Loan Documents). 
  
 “Guaranteed Creditors” means the collective reference to the
Administrative Agent, the Issuing Banks and the Lenders. 
  
 Section 2. Rules of Interpretation. Section 1.03 and Section 1.04 of the Credit Agreement are hereby incorporated herein by reference and shall apply to this Agreement, mutatis mutandis. 
  
 Section 3. Guaranty of Payments. The Subsidiary Guarantor
unconditionally and irrevocably guarantees to the Guaranteed Creditors the punctual payment of the Liabilities, when the same are due and payable, whether on demand, at stated maturity, by acceleration or otherwise, and whether for principal,
interest, fees, expenses, indemnification or otherwise; provided that the maximum liability of the Subsidiary Guarantor shall not exceed the amount which can be guaranteed by the Subsidiary Guarantor under applicable federal and state laws relating
to the insolvency of debtors; provided, further, however, it is understood that the obligations of the Borrower to the Guaranteed Creditors may at any time and from time to time exceed the liability of the Subsidiary Guarantor hereunder without
impairing this Subsidiary Guaranty and the Subsidiary Guarantor and the Guaranteed Creditors agree, as between themselves, that regardless of the manner of application of payments made by the Borrower to the Guaranteed Creditors, all such payments
shall be deemed to be applied first to the portion of the obligations of the Borrower to the Guaranteed Creditors which are not guaranteed hereunder and last to the portion of such obligations which are guaranteed hereunder. This Subsidiary Guaranty
is a guaranty of payment and not of collection only. The Guaranteed Creditors shall not be required to exhaust any right or remedy or take any action against the Borrower or any other person or entity or any collateral. The Subsidiary Guarantor
agrees that, as between the Subsidiary Guarantor and the Guaranteed Creditors, the Liabilities may be declared to be due and payable for the purposes of this Subsidiary Guaranty notwithstanding any stay, injunction or other prohibition which may
prevent, delay or vitiate any declaration as regards the Borrower and that in the event of a declaration or attempted declaration, the Liabilities shall immediately become due and payable by the Subsidiary Guarantor for the purposes of this
Subsidiary Guaranty. No payment made by any Obligor or any other Person or received or collected by the Guaranteed Creditors from any Obligor or any other Person by virtue of any action or proceeding or any set-off or appropriation or application at
any time or from time to time in reduction of or in payment of the Liabilities shall be deemed to 

  

 Exhibit D - 2 

 
modify, reduce, release or otherwise affect the liability of any Subsidiary Guarantor hereunder which shall, notwithstanding any such payment (other than any
payment made by such Subsidiary Guarantor in respect of the Liabilities or any payment received or collected from such Subsidiary Guarantor in respect of the Liabilities), remain liable for the Liabilities up to the maximum liability of such
Subsidiary Guarantor hereunder until the Liabilities are paid in full in cash, no Letter of Credit shall be outstanding and all of the Commitments are terminated. 
  
 Section 4. Guaranty Absolute and Unconditional. The Subsidiary Guarantor guarantees that the
Liabilities shall be paid strictly in accordance with the terms of the Loan Documents. The liability of the Subsidiary Guarantor under this Subsidiary Guaranty is absolute and unconditional irrespective of: (a) any change in the time, manner or
place of payment of, or in any other term of, all or any of the Loan Documents or Liabilities, or any other amendment or waiver of or any consent to departure from any of the terms of any Loan Document or Liabilities, including any increase or
decrease in the rate of interest thereon; (b) any release or amendment or waiver of, or consent to departure from, any other guaranty or support document, or any exchange, release for all or any of the Loan Documents or Liabilities; (c) any present
or future law, regulation or order of any jurisdiction (whether of right or in fact) or of any agency thereof purporting to reduce, amend, restructure or otherwise affect any term of any Loan Document or Liabilities; (d) without being limited by the
foregoing, any lack of validity or enforceability of any Loan Document or Liabilities; (e) the insolvency, bankruptcy arrangement, reorganization, adjustment, composition, liquidation, disability, dissolution or lack of power of the Borrower, any
Subsidiary Guarantor or any other Person at any time liable for the payment of all or part of the Liabilities, including any discharge of, or bar or stay against collecting, any Liability (or any part of them or interest therein) in or as a result
of such proceeding; (f) any sale, lease or transfer of any or all of the assets of the Borrower or any other Subsidiary Guarantor, or any changes in the stockholders of the Borrower or the Subsidiary Guarantor; any change in the corporate existence
(including its constitution, laws, rules, regulations or power), structure or ownership of any Obligor; (g) the absence of any attempt to collect the Obligations or any part of them from any Obligor; (h) any sale, exchange, waiver, surrender or
release of any guarantee or right of offset at any time held by the Guaranteed Creditors for the payment of the Liabilities; (i) the addition, from time to time, of any guarantors, makers or endorsers of the Liabilities, or of any additional
security or collateral for the payment of the Liabilities; and (j) any other setoff, defense or counterclaim whatsoever, or any other circumstance or act whatsoever with respect to the Loan Documents or the transactions contemplated thereby which
might constitute or be construed to constitute a legal or equitable defense available to, or discharge of, the Borrower or a Subsidiary Guarantor under the Credit Agreement or this Subsidiary Guaranty, in bankruptcy or in any other instance (in any
case, except a defense of payment or performance, whether based on contract, tort or any other theory). When making any demand hereunder or otherwise pursuing their rights and remedies hereunder against any Subsidiary Guarantor, the Guaranteed
Creditors may, but shall be under no obligation to, join or make a similar demand on or otherwise pursue or exhaust such rights and remedies as they may have against the Borrower, any other Subsidiary Guarantor or any other Person or against any
guarantee for the Liabilities or any right of offset with respect thereto, and any failure by the Guaranteed Creditors to make any such demand, to pursue such other rights or remedies or to collect any payments from the Borrower, any other
Subsidiary Guarantor or any other Person or to realize upon any such 

  

 Exhibit D - 3 

 
guarantee or to exercise any such right of offset, or any release of the Borrower, any other Subsidiary Guarantor or any other Person or any such guarantee
or right of offset, shall not relieve any Subsidiary Guarantor of any obligation or liability hereunder, and shall not impair or affect the rights and remedies, whether express, implied or available as a matter of law, of the Guaranteed Creditors
against any Subsidiary Guarantor. For the purposes hereof “demand” shall include the commencement and continuance of any legal proceedings. 
  
 Section 5. Guaranty Irrevocable. This Subsidiary Guaranty is a continuing guaranty of all Liabilities now or hereafter existing under the
Loan Documents and shall remain in full force and effect until payment in full of all Liabilities and other amounts payable under this Subsidiary Guaranty and until the Loan Documents are no longer in effect. 
  
 Section 6. Reinstatement. This Subsidiary Guaranty shall
continue to be effective, or be reinstated, as the case may be, if at any time any payment, or any part thereof, of any of the Liabilities is rescinded or must otherwise be returned by the Guaranteed Creditors on the insolvency, bankruptcy,
dissolution, liquidation or reorganization of the Borrower or any Subsidiary Guarantor, all as though the payment had not been made. 
  
 Section 7. No Subrogation. Notwithstanding any payment made by any Subsidiary Guarantor hereunder or any set-off or application of funds of
any Subsidiary Guarantor by the Guaranteed Creditors, no Subsidiary Guarantor shall be entitled to be subrogated to any of the rights of the Guaranteed Creditors against the Borrower or any other Subsidiary Guarantor or any collateral security or
guarantee or right of offset held by any Guaranteed Creditor for the payment of the Liabilities, nor shall any Subsidiary Guarantor seek or be entitled to seek any indemnity, exoneration, participation, contribution or reimbursement from the
Borrower or any other Subsidiary Guarantor in respect of payments made by such Subsidiary Guarantor hereunder, until all amounts owing to the Guaranteed Creditors on account of the Liabilities are irrevocably and indefeasibly paid in full in cash,
no Letter of Credit shall be outstanding and all of the Commitments are terminated. If any amount shall be paid to any Subsidiary Guarantor on account of such subrogation rights at any time when all of the Liabilities shall not have been irrevocably
and indefeasibly paid in full in cash, any Letter of Credit shall be outstanding or any of the Commitments are in effect, such amount shall be held by such Subsidiary Guarantor in trust for the Guaranteed Creditors, and shall, forthwith upon receipt
by such Subsidiary Guarantor, be turned over to the Administrative Agent in the exact form received by such Subsidiary Guarantor (duly indorsed by such Subsidiary Guarantor to the Administrative Agent, if required), to be applied against the
Liabilities, whether matured or unmatured, as determined by the Administrative Agent. 
  
 Section 8. Subordination. Without limiting the Guaranteed Creditors’ rights under any other agreement, any liabilities owed by the Borrower to the Subsidiary Guarantor in connection with any
extension of credit or financial accommodation by the Subsidiary Guarantor to or for the account of the Borrower, including but not limited to interest accruing at the agreed contract rate after the commencement of a bankruptcy or similar
proceeding, are hereby subordinated to the Liabilities upon the occurrence of an Event of Default, and, in such an event such liabilities of the Borrower to the Subsidiary Guarantor, if the Administrative Agent so requests, shall be 

  

 Exhibit D - 4 

 
collected, enforced and received by the Subsidiary Guarantor as trustee for the Guaranteed Creditors and shall be paid over to the Administrative Agent for
the benefit of the Guaranteed Creditors on account of the Liabilities (but only to the extent due and payable but without reducing or affecting in any manner the liability of the Subsidiary Guarantor under the other provisions of this Subsidiary
Guaranty. 
  
 Section 9. Payments Generally. All
payments by the Subsidiary Guarantor shall be made in the manner, at the place and in the currency (the “Payment Currency”) required by the Loan Documents; provided, however, that (if the Payment Currency is other than U.S. dollars) the
Subsidiary Guarantor may, at its option (or, if for any reason whatsoever the Subsidiary Guarantor is unable to effect payments in the foregoing manner, the Subsidiary Guarantor shall be obligated to) pay to the Administrative Agent at its principal
office, for the benefit of the Guaranteed Creditors, the equivalent amount in U.S. dollars computed at the selling rate of the Administrative Agent or a selling rate chosen by the Administrative Agent, most recently in effect on or prior to the date
the Liability becomes due, for cable transfers of the Payment Currency to the place where the Liability is payable. In any case in which the Subsidiary Guarantor makes or is obligated to make payment in U.S. dollars, the Subsidiary Guarantor shall
hold the Administrative Agent and the Guaranteed Creditors harmless from any loss incurred by the Administrative Agent or the Guaranteed Creditors arising from any change in the value of U.S. dollars in relation to the Payment Currency between the
date the Liability becomes due and the date the Guaranteed Creditors are actually able, following the conversion of the U.S. dollars paid by the Subsidiary Guarantor into the Payment Currency and remittance of such Payment Currency to the place
where such Liability is payable, to apply such Payment Currency to such Liability. 
  
 Section 10. Certain Taxes. The Subsidiary Guarantor further agrees that all payments to be made hereunder shall be made without setoff or counterclaim and free and clear of, and without deduction for,
any Indemnified Taxes and Other Taxes. If any Indemnified Taxes and Other Taxes are required to be withheld from any amounts payable to the Administrative Agent for the benefit of the Guaranteed Creditors hereunder, the amounts so payable to the
Administrative Agent for the benefit of the Guaranteed Creditors shall be increased to the extent necessary to yield to the Guaranteed Creditors (after payment of all Indemnified Taxes and Other Taxes) the amounts payable hereunder in the full
amounts so to be paid. Whenever any Indemnified Taxes and Other Taxes are paid by the Subsidiary Guarantor, as promptly as possible thereafter, the Subsidiary Guarantor shall send the Administrative Agent an official receipt showing payment thereof,
together with such additional documentary evidence as may be required from time to time by the Administrative Agent. 
  
 Section 11. Representations and Warranties. The Subsidiary Guarantor represents and warrants that: (a) this Subsidiary Guaranty (i) has been
authorized by all necessary corporate action; (ii) does not violate any agreement, instrument, law, regulation or order applicable to the Subsidiary Guarantor; (iii) does not require the consent or approval of, registration or filing with, or any
other action by, any Governmental Authority; and (iv) is the legal, valid and binding obligation of the Subsidiary Guarantor enforceable against the Subsidiary Guarantor in accordance with its terms, subject to applicable bankruptcy, insolvency,
reorganization, moratorium, or other laws affecting creditors’ rights generally and subject to 

  

 Exhibit D - 5 

 
general principles of equity regardless of whether considered in a proceeding in equity or at law; and (b) in executing and delivering this Subsidiary
Guaranty, the Subsidiary Guarantor has (i) without reliance on the Administrative Agent or the Guaranteed Creditors or any information received from the Administrative Agent or the Guaranteed Creditors and based upon such documents and information
it deems appropriate, made an independent investigation of the transactions contemplated hereby and the Borrower, the Borrower’s business, assets, operations, prospects and condition, financial or otherwise, and any circumstances which may bear
upon such transactions, the Borrower or the obligations and risks undertaken herein with respect to the Liabilities; (ii) adequate means to obtain from the Borrower on a continuing basis information concerning the Borrower; (iii) has full and
complete access to the Loan Documents and any other documents executed in connection with the Loan Documents; and (iv) not relied and will not rely upon any representations or warranties of the Administrative Agent or the Guaranteed Creditors not
embodied herein or any acts heretofore or hereafter taken by the Administrative Agent or the Guaranteed Creditors (including but not limited to any review by the Administrative Agent or the Guaranteed Creditors of the affairs of the Borrower).

remedies provided in this Subsidiary Guaranty are cumulative and not exclusive of any remedies provided by law.

 Section 14. Amendments and Waivers to Guaranty. No amendment or waiver of any provision of this Subsidiary Guaranty, nor consent to
any departure by the Subsidiary Guarantor therefrom, shall be effective unless it is in writing and signed by each of the Guaranteed Creditors, and then the waiver or consent shall be effective only in the specific instance and for the specific
purpose for which given. No failure on the part of the Guaranteed Creditors to exercise, and no delay in exercising, any right under this Subsidiary Guaranty shall operate as a waiver or preclude any other or further exercise thereof or the exercise
of any other right. Each Subsidiary Guarantor hereby waives any and all notice of the creation, renewal, extension or accrual of any of the Liabilities and notice of or proof of reliance by the Guaranteed Creditors upon this Subsidiary Guaranty or
acceptance of this Subsidiary Guaranty; the Liabilities, and any of them, shall conclusively be deemed to have been created, contracted or incurred, or renewed, extended, amended or waived, in reliance upon this Subsidiary Guaranty and no notice of
creation of the Liabilities or any extension of credit already or hereafter contracted by or extended to the Borrower need be given to any Subsidiary Guarantor; and all dealings between the Borrower and any of the Subsidiary Guarantors, on the one
hand, and the Guaranteed Creditors, on the other hand, likewise shall be conclusively presumed to have been had or consummated in reliance upon this Subsidiary Guaranty. Each Subsidiary Guarantor waives diligence, presentment, protest, demand for
payment and notice of default or nonpayment to or upon the Borrower or any of the Subsidiary Guarantors with respect to the Liabilities.

Creditors in connection with the enforcement of this Subsidiary Guaranty. Attorneys’ fees reimbursed by the Subsidiary Guarantor in connection with this Subsidiary Guaranty shall be for a single law firm per country (unless conflicts (including
conflicts between the Administrative Agent, the Co-Arrangers and the other Lenders as determined in the reasonable discretion of the Required Lenders) otherwise prohibit the engagement of a single law firm) plus a single local counsel in each
jurisdiction where local counsel is reasonably required.

assigns; provided that the Subsidiary Guarantor may not assign or transfer its rights or obligations under this Subsidiary Guaranty. Without limiting the generality of the foregoing: (a) the obligations of the Subsidiary Guarantor under this
Subsidiary Guaranty shall continue in full force and effect and shall be binding on any successor partnership and on previous partners and their respective estates if the Subsidiary Guarantor is a partnership, regardless of any change in the
partnership as a result of death retirement or otherwise; and (b) the Guaranteed Creditors may assign, sell participations in or otherwise transfer their rights under the Loan Documents to another person or entity to the extent expressly permitted
