 ARTICLE II 
 The Credits 
  
 SECTION 2.01. Commitments. Subject to the terms and conditions set forth herein, each Lender, severally and for itself alone, agrees to make Loans to the Borrower from time to time during the Availability Period in an aggregate
principal amount that will not result in such Lender’s Revolving Credit Exposure exceeding such Lender’s Commitment. 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. 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 2.13, 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 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 $50,000 and not less than $250,000. At the time that each
ABR Borrowing is made, such Borrowing shall be in an aggregate amount that is an integral multiple of $50,000 and not less than $250,000; 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 reimbursement of an LC Disbursement as contemplated by Section 2.04(e). Borrowings of more than one Type may be 

  

 20 

 
outstanding at the same time; provided that there shall not at any time be more than a total of ten (10) 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 as a Eurodollar Borrowing if a Default shall have occurred and be continuing, or if the Interest Period requested with respect thereto would end after the
Maturity Date. 
  
 SECTION 2.03. Requests for Borrowings.
To request a Borrowing, the Borrower shall notify the Administrative Agent of such request by telephone (a) in the case of a Eurodollar Borrowing, not later than 10:00 a.m., Houston, Texas, time, three Business Days before the date of the proposed
Borrowing or (b) in the case of an ABR Borrowing, not later than 10:00 a.m., Houston, Texas, time, one Business Day before the date of the proposed Borrowing; provided that any such notice of an ABR Borrowing to finance the reimbursement of
an LC Disbursement as contemplated by Section 2.04(e) may be given not later than 10:00 a.m., Houston, Texas, time, on the date 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 Borrowing Request 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 2.05. 

 
 If no election as to the Type of Borrowing is specified, the requested Borrowing shall be
an ABR Borrowing. If no Interest Period is specified with respect to any requested Eurodollar Borrowing, 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 2.04. Letters of Credit  
  
 (a) General. Subject to the terms and conditions set forth herein, the
Borrower may request the issuance of Letters of Credit for its own account, in a form reasonably acceptable to the Administrative Agent and the Issuing Bank, at any time and from time to time during the Availability Period. 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, Letter of 

  

 21 

 
Credit Agreement or other agreement submitted by the Borrower to, or entered into by the Borrower with, the Issuing Bank relating to any Letter of Credit,
the terms and conditions of this Agreement shall control. 
  
 (b)
Notice of Issuance, Amendment, Renewal, Extension; Certain Conditions. To request the issuance of a Letter of Credit (or the amendment, renewal 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 Issuing Bank) to the Issuing Bank and the Administrative Agent (reasonably in advance of the requested date of issuance, amendment, renewal or extension) a
notice requesting the issuance of a Letter of Credit, or identifying the Letter of Credit to be amended, renewed or extended, and specifying the date of issuance, amendment, renewal 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) of this Section), 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, renew or extend such Letter of Credit. If requested by the Issuing Bank, the Borrower also shall submit a Letter of Credit Agreement in connection with any request for a Letter of Credit. A Letter of Credit shall be issued, amended, renewed
or extended only if (and upon issuance, amendment, renewal or extension of each Letter of Credit the Borrower shall be deemed to represent and warrant that), after giving effect to such issuance, amendment, renewal or extension the aggregate LC
Exposures of all the Lenders at that time shall not exceed $5,000,000 and the total Revolving Credit Exposure of all Lenders shall not exceed the total Commitments at that time. On each day during the period commencing with the issuance of an Letter
of Credit and until such Letter of Credit shall have expired or been terminated, the Commitment of each Lender shall be deemed to be utilized for all purposes of this Agreement in an amount equal to such Lender’s Applicable Percentage of the
sum of (i) the undrawn amount of such Letter of Credit plus (ii) the unpaid amount of all LC Disbursements with respect to such Letter of Credit. 
  
 (c) Expiration Date. Each Letter of Credit shall expire at or prior to the close of business on December 30, 2007. After the termination of the
Availability Period, no Letter of Credit may be issued, amended, renewed or extended. After the termination of the Availability Period, all terms of this Agreement (other than Sections 2.01, 2.02, 2.03, 2.06, 2.07, 2.09, 2.10, 2.13, 2.15, and
2.19, Article III and Article IV) shall survive and remain in effect for the benefit of the Administrative Agent, the Issuing Bank, the Lenders, the Indemnitees, and all other parties benefited thereby, notwithstanding the termination of the
Availability Period, until each Lender’s LC Exposure is zero and all obligations of the Borrower, under Section 2.04 and otherwise, with respect to any such LC Exposure have been fully and finally satisfied. 
  
 (d) Participations. 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 the Issuing Bank or the Lenders, the Issuing Bank hereby grants to each Lender, and each Lender hereby acquires from the 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 Issuing Bank, such Lender’s Applicable Percentage of each LC Disbursement made by the Issuing Bank and not reimbursed by the Borrower on the date due as
provided in paragraph (e) of this Section, or 

  

 22 

 
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 the 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 in immediately available funds an amount equal to such LC Disbursement not later than 12:00 noon, Houston, Texas, time, on the date that such LC Disbursement is made, if the
Borrower shall have received notice of such LC Disbursement prior to 10:00 a.m., Houston, Texas, 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, Houston,
Texas, time, on (i) the Business Day that the Borrower receives such notice, if such notice is received prior to 10:00 a.m., Houston, Texas, 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 $250,000 or more, the Borrower may, subject to the conditions to borrowing set forth herein, request in
accordance with Section 2.03 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 amount drawn under any Letter of Credit is in non-United States currency (“foreign currency”), the Borrower shall pay the United States dollar equivalent of the amount computed at the Issuing Bank’s selling rate, as
of the date of Borrower’s payment, for cable transfers of such foreign currency to the place of payment; provided, further, that if, for any reason, the Issuing Bank has no selling rate for cable transfers of that currency to such
place on the payment date, the Borrower shall pay an amount in United States currency equivalent to the Issuing Bank’s actual cost of settlement of its obligation. All rights, powers, benefits and privileges of this Agreement and the other Loan
Documents with respect to the Loans, all security therefor and guaranties thereof and all restrictions, provisions for repayment or acceleration and all other covenants, warranties, representations and agreements of the Borrower contained in this
Agreement with respect to the Loans shall apply to each LC Disbursement. 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 2.05 with respect to Loans made by such Lender (and Section 2.05 shall apply, mutatis mutandis, to the payment obligations of the Lenders), and the Administrative Agent shall promptly pay to
the 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
Issuing Bank or, to the extent that Lenders have made payments pursuant to this paragraph to reimburse the Issuing Bank, then to such Lenders and the Issuing Bank as their interests may appear. Any payment made by a Lender pursuant to this paragraph
to reimburse the Issuing Bank for any LC 

  

 23 

 
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) of this Section shall be absolute, unconditional and irrevocable, and shall be performed strictly in accordance with the terms of this
Agreement and each applicable Letter of Credit 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)
payment against presentation of any draft or other document presented under a Letter of Credit that proves to be forged, fraudulent or invalid in any respect or any statement therein being untrue or inaccurate in any respect, or which is signed,
issued or presented by a Person (or a transferee of such Person) purporting to be a successor or transferee of the beneficiary of such Letter of Credit; (iii) the Issuing Bank or any of its branches or affiliates being the beneficiary of any Letter
of Credit; (iv) any correspondent of the Issuing Bank with respect to a Letter of Credit honoring a drawing under any drawing document up to the amount available under any Letter of Credit even if such drawing document claims an amount in excess of
the amount available under the Letter of Credit; (v) the existence of any claim, set-off, defense or other right that the Borrower or any other Person may have at any time against any beneficiary, any assignee of proceeds, the Issuing Bank or any
other Person; (vi) the Issuing Bank’s or any correspondent’s having previously paid against fraudulently signed or presented drawing documents (whether or not the Borrower reimbursed the Issuing Bank for such drawing); or (vii) any other
event or circumstance whatsoever, 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 Bank, 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 the Issuing Bank;
provided that the foregoing shall not be construed to excuse the Issuing Bank from 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 the 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 the Issuing Bank (as finally determined by a court of competent jurisdiction), the 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, the Issuing Bank may, in its sole discretion, but without any obligation to do so, 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. 
  

 24 

 (g) Disbursement Procedures. The Issuing Bank shall, promptly following its receipt thereof,
examine all documents purporting to represent a demand for payment under a Letter of Credit. The Issuing Bank shall promptly notify the Administrative Agent and the Borrower by telephone (confirmed by telecopy) of such demand for payment and whether
the Issuing Bank has made or 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 the Issuing Bank and the Lenders with respect
to any such LC Disbursement. 
  
 (h) Interim Interest. If
the 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) of this Section, then Section 2.12(d)(i) shall apply. Interest accrued pursuant to this paragraph shall be for the account of the 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 the Issuing Bank shall be for the account of such Lender to the extent of such payment. 
  

(i) Assumption of Risk by Borrower. Subject to paragraph (f) of this Section, as among the Borrower, the Issuing Bank and the Lenders,
the Borrower assumes all risks of the acts and omissions of, or misuse of any of the Letters of Credit by, the respective beneficiaries of such Letters of Credit. In furtherance and not in limitation of the foregoing, subject to the provisions of
the applications for the issuance of Letters of Credit, neither the Lenders, the Issuing Bank, nor the Administrative Agent shall be responsible for: 
  
 (i) the validity, sufficiency, accuracy, genuineness, or legal effect of any document submitted by any Person in connection with the
application for, and issuance of, and presentation of drafts with respect to, any of the Letters of Credit, even if it should prove to be in any or all respects invalid, insufficient, inaccurate, fraudulent, or forged; 
  
 (ii) the validity or sufficiency of any instrument
transferring or assigning, or purporting to transfer or assign, any Letter of Credit or the rights or benefits thereunder or proceeds thereof, in whole or in part, which may prove to be invalid or ineffective for any reason; 
  
 (iii) the failure of the beneficiary of any Letter of Credit
to comply with conditions required in order to draw upon such Letter of Credit, other than those conditions the failure to comply with which is significant and readily apparent on the face of a document submitted in connection with a requested draw
under the Letter of Credit; 
  
 (iv) errors,
omissions, interruptions, or delays in transmission or delivery of any messages, by mail, cable, telegraph, telex, or otherwise, whether or not they be in cipher; 
  
 (v) errors in interpretation of technical terms; 
  

 25 

 (vi) any loss or delay in the transmission or otherwise of any document required in order
to make a drawing under any Letter of Credit or of the proceeds thereof; 
  
 (vii) the misapplication by the beneficiary of any Letter of Credit of the proceeds of any drawing under such Letter of Credit; or 
  
 (viii) any consequence arising from causes beyond the control of any Lender, the Administrative Agent or the
Issuing Bank, including, without limitation, any act of any Governmental Authority. 
  
 (j) Replacement of the Issuing Bank. The 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 the 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 2.11(b). From and after the effective date of any such replacement, (i) the successor Issuing Bank shall have all the rights and obligations of the 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. 
  
 (k) Cash Collateralization. If any Event of Default shall occur and be continuing, or at any time after the termination of the Availability Period whether or not an Event of Default shall have occurred and be
continuing, on the Business Day that the Borrower receives notice from the Administrative Agent or the Required Lenders (or, if the maturity of the Loans has been accelerated, Lenders with LC Exposure representing greater than 25% of the total LC
Exposure) 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 thereon; provided that the obligation to deposit such cash collateral shall become effective immediately, and such deposit shall become 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 Section 7.01. 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. Other than any interest
earned on the investment of such deposits, which investments shall be made only in Permitted Investments and only at the written direction of the Borrower and at the Borrower’s risk and expense, such deposits shall not bear interest. The
Administrative Agent shall have no obligation to invest any such deposits. 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 the
Issuing Bank for LC Disbursements for which it has not been reimbursed and, to the extent not so applied, shall be held for the satisfaction of the 

  

 26 

 
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 25% of the total LC Exposure), be applied to satisfy other obligations of the Borrower under this Agreement. If the Borrower is required to provide an amount of cash collateral hereunder as a
result of the occurrence of an Event of Default, such amount (to the extent not applied as aforesaid) shall be returned to the Borrower within three Business Days after all Events of Default have been cured or waived. 
  
 (l) Standards. Each Letter of Credit shall be subject to (A) either
(i) the Uniform Customs and Practice for Documentary Credits (1993 Revision), International Chamber of Commerce Publication No. 500 (and any subsequent revision thereof approved by a Congress of the International Chamber of Commerce) or (ii) the
International Standby Practices 1998, as appropriate, and, (B) to the extent not inconsistent therewith, the laws of the State of New York. Without in any way limiting any of the foregoing, the Borrower and each Lender acknowledge that the Issuing
Bank shall have no greater responsibility in the operation of the Letters of Credit than is specified in the Uniform Customs and Practice of Documentary Credits (1993 Revision), International Chamber of Commerce Publication No. 500, or the
International Standby Practices 1998, as the case may be. 
  
 (m)
Increased Costs. If, after the date of this Agreement, as a result of any change in any Legal Requirement, or the interpretation thereof by any Governmental Authority, or any Change in Law, there shall be imposed, modified or deemed
applicable any tax, reserve, special deposit or similar requirement against or with respect to or measured by reference to Letters of Credit issued or to be issued hereunder or participations in such Letters of Credit, and the result shall be to
increase the cost to the Issuing Bank or any other Lender of issuing or maintaining any Letter of Credit or any participation therein, or reduce any amount receivable by the Issuing Bank or any other Lender hereunder in respect of any Letter of
Credit or any participation therein (which increase in cost, or reduction in amount receivable, shall be the result of the reasonable allocation by the Issuing Bank or such other Lender, as the case may be, of the aggregate of such increases or
reductions resulting from such event; the determination of such amount by the Issuer or such other Lender, as the case may be, shall be conclusive and binding, absent manifest error), then the Issuing Bank or such other Lender shall notify the
Borrower or the Administrative Agent, as the case may be, and upon demand therefor by the Administrative Agent, the Borrower (subject to Section 9.18) shall pay to the Issuing Bank or such other Lender, from time to time as specified by the
Issuer or such other Lender through the Administrative Agent, such additional amounts as shall be sufficient to compensate the Issuing Bank or such other Lender for such increased costs or reductions in amount. 
  
 SECTION 2.05. 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 12:00 noon, Houston, Texas, time, to the account of the Administrative Agent most recently designated by it for such purpose by notice to the Lenders. 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 in Houston, Texas, and designated by the Borrower in the applicable
Borrowing Request; provided that ABR Loans made to finance the 

  

 27 

 
reimbursement of an LC Disbursement as provided in Section 2.04(e) shall be remitted by the Administrative Agent to the Issuing Bank. 
  
 (b) Unless the Administrative Agent shall have received notice from a Lender
prior to the proposed date 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 on such
date 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 ABR Loans. If such Lender pays such amount to the Administrative Agent, then such amount shall constitute such
Lender’s Loan included in such Borrowing. 
  
 SECTION 2.06.
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 2.03 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 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); 
  

 28 

 (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, 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 a 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 a 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 2.07. Termination and Reduction of Commitments. 
  
 (a) Unless previously terminated, the Commitments shall terminate on the Maturity Date (except that Letters of Credit issued before that date may remain
outstanding in accordance with their terms and this Agreement). 
  
 (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 $50,000 and not less than $250,000,
and (ii) the Borrower shall not terminate or reduce the Commitments if, after giving effect to any concurrent prepayment of the Loans in accordance with Section 2.10, the sum of the Revolving Credit Exposures would exceed the total
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 

  

 29 

 
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 Commitments. 
  
 (d) The Commitments may not be reinstated after they have been terminated or
increased after they have been reduced. 
  
 SECTION 2.08.
Repayment. The Borrower hereby unconditionally promises to pay to the Administrative Agent for the account of each Lender, on the Maturity Date, the aggregate principal amount of all Loans and LC Disbursements then outstanding, all accrued
and unpaid fees under the Loan Documents, all accrued and unpaid interest under the Loan Documents, and all other Obligations accrued and unpaid on such date. The Borrower hereby unconditionally promises to pay to the Administrative Agent for the
account of each Lender, when due, all LC Disbursements which may become due after the Maturity Date, together with all accrued and unpaid fees, all accrued and unpaid interest, and all other Obligations that may accrue under or in connection with
this Agreement or any Letter of Credit on or after the Maturity Date. 
  
 SECTION 2.09. Notes. 
  
 All Loans made by a
Lender shall be evidenced by a single Note, dated the date of this Agreement (or such appropriate later date if such Lender is a party to an Assignment and Acceptance), payable to the order of such Lender in a principal amount equal to the
Commitment of such Lender as originally in effect and otherwise duly completed. Each Lender is hereby authorized by the Borrower to endorse on the schedule (or a continuation thereof attached to the Note of such Lender, to the extent applicable) the
date, amount and Type of, and the Interest Period (as applicable) for each applicable Loan made by such Lender to the Borrower and the amount of each payment or prepayment of principal of such Loan received by such Lender; provided that any
failure by such Lender to make any such endorsement shall not affect the obligations of the Borrower or any other Obligor under any Note or this Agreement or any other Loan Document in respect of any such Loan. 
  
 SECTION 2.10. Prepayment of Loans. 
  
 (a) The Borrower shall have the right at any time and from time to time to
prepay any Borrowing in whole or in part, 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 10:00 a.m., Houston, Texas, time, three Business Days before the date of prepayment, and (ii) in the case of prepayment of an ABR Borrowing, not later than 10:00 a.m., Houston, Texas, time, one Business Day
before 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 2.07, 

  

 30 

 
then such notice of prepayment may be revoked if such notice of termination is revoked in accordance with Section 2.07. Promptly following receipt of
any such notice, 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 and unpaid interest to the extent required by Section 2.12. The
Borrower shall reimburse the Administrative Agent on demand for any loss, cost of expense incurred or sustained as a result of any such prepayment in accordance with Section 2.12. 
  
 SECTION 2.11. 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 rate of 0.25% per
annum on the daily amount of the unused Commitment of such Lender during the period from and including the Effective Date to but excluding the date on which such Commitment terminates. Accrued and unpaid commitment fees shall be due in arrears on
the last day of each March, June, September and December, beginning March 31, 2003, and on the date on which the Commitments terminate, commencing on the first such date to occur after the date hereof. Subject to Section 9.18, all commitment
fees shall be computed on the basis of a year of 360 days 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 on each day at a rate per annum equal to the Eurodollar Margin in effect on such day (as determined in accordance with the table set forth in the definition of “Applicable
Margin” above) on the amount of such Lender’s LC Exposure on such day (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; provided, however, that in no event shall the aggregate participation fees payable to all Lenders in any one-year
period be less than $500, and (ii) to the Issuing Bank a fronting fee, which shall accrue at the rate of 0.125% per annum on the average daily amount of the aggregate 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 of termination of the Commitments and the date on which there ceases to be any LC Exposure, as well as the Issuing Bank’s standard
fees with respect to the issuance, amendment, renewal or extension of any Letter of Credit or processing of drawings thereunder. Accrued and unpaid participation fees and fronting fees for each Letter of Credit shall be due in arrears on the last
day of each March, June, September and December, beginning March 31, 2003; provided that all accrued and unpaid such fees shall be payable on the date on which the Commitments terminate, and all such fees accruing after the termination of the
Availability Period shall be due on demand. Any other fees payable to the Issuing Bank pursuant to this paragraph shall be due within 10 days after demand. Subject to Section 9.18, all participation fees and fronting fees shall be computed on
the basis of a year of 360 days and shall be payable for the actual number of days elapsed (including the first day but excluding the last day). 
  

 31 

 (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 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 the 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 2.12. Interest. 
  
 (a) The Loans comprising each ABR Borrowing shall bear interest at the lesser of (i) the Alternate Base Rate from time to time in effect plus the
Applicable Margin from time to time in effect and (ii) the Maximum Rate. 
  
 (b) The Loans comprising each Eurodollar Borrowing shall bear interest at the lesser of (i) the Adjusted LIBO Rate for the Interest Period in effect for such Borrowing plus the Applicable Margin from time to time in
effect and (ii) the Maximum Rate. 
  
 (c) Notwithstanding the
foregoing, but subject to Section 9.18, if any principal of or interest on any Loan or any LC Disbursement 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, not to exceed the Maximum Rate, 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, not to exceed the Maximum Rate. 
  
 (d) Accrued and unpaid interest on each Loan shall be due 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 due 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 and unpaid interest on the principal amount repaid or prepaid shall be due 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 and unpaid interest on such Loan shall be due on the effective date of such conversion. 
  
 (e) Subject to Section 9.18, 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 at times when the Alternate Base Rate is based on the Prime 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. 
  

 32 

 SECTION 2.13. Alternate Rate of Interest. If prior to the commencement of any Interest Period for
a Eurodollar Borrowing: 
  
 (a) Dollar deposits
are not being offered to banks in the London interbank Dollar market for the amount and Interest Period of such Eurodollar Loan; 
  
 (b) 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 
  
 (c) the Administrative Agent is advised by the Required Lenders that the Adjusted LIBO Rate for such Interest Period will not adequately
and fairly reflect the cost to such Lenders (or Lender) of making or maintaining their Loans (or its Loan) 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 2.14. 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 the Issuing Bank; or 
  
 (ii) impose on any Lender or the Issuing Bank or the London interbank dollar market any other condition affecting this Agreement or
Eurodollar Loans made by such Lender or any Letter of Credit or any participation therein; 
  
 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 the 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 the Issuing Bank hereunder (whether of principal, interest or otherwise), then,
subject to Section 9.18, the Borrower will pay to such Lender or the Issuing Bank, as the case may be, such additional amount or amounts as will compensate such Lender or the Issuing Bank, as the case may be, for such additional costs
incurred or reduction suffered. 
  
 (b) If any Lender or the
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 

  

 33 

 
or the Issuing Bank’s capital or on the capital of such Lender’s or the 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 the Issuing Bank, to a level below that which such Lender or the 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 the 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, subject to Section 9.18, the Borrower will pay to such Lender or the Issuing Bank, as the case may be, such additional amount or amounts as will compensate such Lender or the Issuing Bank
or such Lender’s or the Issuing Bank’s holding company for any such reduction suffered. 
  
 (c) A certificate of a Lender or the Issuing Bank setting forth the amount or amounts necessary to compensate such Lender or the 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 such Lender or the 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 the Issuing Bank to demand compensation pursuant to this Section shall not constitute a waiver of such Lender’s or the Issuing Bank’s right to demand such
compensation; provided that the Borrower shall not be required to compensate a Lender or the 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 the
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 the 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 270-day period referred to above shall be extended to include the period of retroactive effect thereof. 
  
 SECTION 2.15. 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 2.07(c) 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,
subject to Section 9.18, 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 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 

  

 34 

 
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 shall be delivered to the Borrower and shall be conclusive absent manifest error. The Borrower shall pay such Lender the amount shown as due on any such certificate within 10 days after
receipt thereof. 
  
 SECTION 2.16. 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 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 the 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 the 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 delivered to the Borrower by a Lender or the Issuing Bank, or by the Administrative Agent on its own behalf or on behalf of a Lender or the Issuing
Bank, 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. 
  
 (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. 
  

 35 

 (f) If the Administrative Agent or a Lender determines, in its sole discretion, 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 2.16, 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 2.16 with respect to the Taxes or Other Taxes giving rise to such refund), net of all 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. 
  
 SECTION 2.17. Illegality.
If at any time any Lender determines that any Law has made it unlawful, or that any Governmental Authority has asserted that it is unlawful, for such Lender to make, maintain or fund Eurodollar Loans, or materially restricts the authority of such
Lender to purchase or sell, or to take deposits of, the applicable offshore Dollar market, or to determine or charge interest rates based upon the Adjusted LIBO Rate, then, on notice thereof by such Lender (through the Administrative Agent) to the
Borrower, any obligation of such Lender Agent to make or continue Eurodollar Loans or to convert ABR Loans to Eurodollar Loans shall be suspended until such Lender (through the Administrative Agent) notifies the Borrower that the circumstances
giving rise to such determination no longer exist. Upon receipt of such notice, the Borrower shall, upon demand from such Lender (through the Administrative Agent), prepay or, if applicable, convert all Eurodollar Loans to ABR Loans, either on the
last day of the Interest Period thereof, if such Lender may lawfully continue to maintain such Eurodollar Loans to such day, or immediately, if such Lender may not lawfully continue to maintain such Eurodollar Loans. Upon any such prepayment or
conversion, the Borrower shall also pay interest on the amount so prepaid or converted. If a Lender gives a notice under this Section, such Lender shall, upon the request of the Borrower, 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 sole judgment of such Lender, such designation (i) would eliminate the need for such
notice 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 such Lender in connection
with any such designation. 
  
 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 2.14, 2.15 or 2.16, or otherwise) prior to 12:00 noon,
Houston, Texas 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 

  

 36 

 
calculating interest thereon. All such payments shall be made to the Administrative Agent at its offices at 712 Main Street, Houston, Texas, except payments
to be made directly to the Issuing Bank as expressly provided herein and except that payments pursuant to Sections 2.14, 2.15, 2.16 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 (unless the result of such extension of time would be to extend the date of such payment into another calendar month (in the case of a Eurodollar Loan) or (in the case of any Loan) beyond the Maturity
Date, and in either such event such payment shall be due on the Business Day immediately preceding the day on which such payment would otherwise have been due), and, in the case of any payment accruing interest, interest thereon shall be due 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’s 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 Loans; 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. 
  

 37 

 (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 Bank 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 Bank, 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 Bank, 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 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 2.04(c) or (e), 2.05(b) or 2.18(d), 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 2.14, 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 2.16, 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 2.14 or 2.16,
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 requests compensation under Section 2.14, 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 2.16, or if
any Lender defaults in its obligation to fund Loans hereunder, 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 another Lender, if a Lender
accepts such assignment); provided that (i) the Borrower shall have received the prior written consent of the Administrative Agent, which consent shall not unreasonably be withheld, (ii) such Lender shall have received payment of an amount
equal to the outstanding principal of its Loans and participations in LC Disbursements, accrued and unpaid interest thereon, accrued and unpaid 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 2.14 or 

  

 38 

 
payments required to be made pursuant to Section 2.16, 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 or otherwise, the circumstances entitling the Borrower to require such assignment and delegation cease to apply.

and in the amounts customarily insured against by such entities and carry such other insurance as is usually carried by such entities (which may, to the extent such entities are self-insured against certain risks, include self-insurance);
provided, however, that in any event the Borrower and its consolidated Subsidiaries will maintain (subject to the preceding self-insurance provisions): 
  

(i) Property Insurance. Insurance against loss or damage covering substantially all of the tangible real and personal Property
of such Person by reason of any Peril (as defined below) in such amounts as shall be reasonable and customary and sufficient to avoid the insured named therein from becoming a co-insurer of any loss under such policy, but in any event in such
amounts as are reasonably available as determined by the Borrower’s independent insurance broker. 
  

 49 

 (ii) Automobile Liability Insurance for Bodily Injury and Property Damage.
Insurance in respect of all vehicles (whether owned, hired or rented by such Person) at any time located at, or used in connection with, its Properties or operations against liabilities for bodily injury and Property damage in such amounts as are
then customary for vehicles used in connection with similar Properties and businesses, but in any event to the extent required by applicable law. 
  
 (iii) Comprehensive General Liability Insurance. Insurance against claims for bodily injury, death, or Property damage occurring
on, in or about the real property of such Person, in such amounts as are then customary for Property similar in use in the jurisdictions where such Properties are located. 
  
 (iv) Workers’ Compensation Insurance. Workers’ compensation insurance (including
employers’ liability insurance) to the extent required by applicable law, which may be self-insurance to the extent permitted by applicable law. 
  
 All insurance shall be written by financially responsible companies selected by the Borrower and its Subsidiaries reasonably acceptable to the Administrative Agent. For
purposes hereof, the term “Peril” shall mean, collectively, fire, lightning, flood, windstorm, hail, explosion, riot and civil commotion, vandalism and malicious mischief, damage from aircraft, vehicles, and smoke, and other perils
covered by the “all-risk” endorsement then in use in the jurisdictions where the Properties of the Borrower and its Subsidiaries, as the case may be, are located. 
  
 SECTION 5.07. Books and Records; Inspection Rights. The Borrower will, and will cause each of its consolidated
Subsidiaries to, keep proper books of record and account in which full, true and correct entries are made of all dealings and transactions in relation to its business and activities. The Borrower will, and will cause each of its consolidated
Subsidiaries to, permit any representatives designated by the Administrative Agent or any Lender, upon reasonable prior notice, (i) to visit and inspect its properties, (ii) to examine and make extracts from its books and records, and (iii) to
discuss its affairs, finances and condition with its officers and independent accountants, in each case at such reasonable times and as often as reasonably requested. 
  
 SECTION 5.08. Compliance with Laws. The Borrower will, and will cause each of its consolidated Subsidiaries to,
comply with all Laws 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. 
  
 SECTION 5.09. Further Assurances. The Borrower will execute and
deliver, and will cause each of its consolidated Subsidiaries to execute and deliver, such further agreements, documents, and instruments and take such further actions as may be requested by the Administrative Agent to carry out the terms and
provisions and purposes of this Agreement and the other Loan Documents and to evidence the Obligations. Without limiting the generality of the foregoing, the Borrower will take all necessary actions to and otherwise ensure that, at all times, the
Obligations will rank at least pari passu in respect of priority of treatment with all other present and future Indebtedness of the Borrower (excluding rights of secured parties with respect to Permitted Liens). 
  

 50 

 SECTION 5.10. ERISA. The Borrower will, and will cause each of its consolidated Subsidiaries and
each ERISA Affiliate to, comply with all minimum funding requirements and all other material requirements of ERISA so as not to give rise to any liability thereunder. 
  
 SECTION 5.11. Delivery of Certain Amendments and Funded Debt Documents. The Borrower will, and will cause each of its
consolidated Subsidiaries to, promptly deliver to the Administrative Agent any amendment, modification, or supplement to (a) the certificate or articles of incorporation, articles of organization, bylaws, regulations, or other Organizational

 SECTION 5.12. Use of
Proceeds and Letters of Credit. The Borrower shall use the proceeds of the Loans only to refinance existing indebtedness and finance the ongoing working capital and general corporate requirements of the Borrower and its consolidated
Subsidiaries, including the issuance of Letters of Credit, and not for any purpose that would violate any Law. No part of the proceeds of any Loan (and no Letter of Credit) will be used, whether directly or indirectly, to purchase or carry any
margin stock (as such term is used in Regulation U of the Board) or for any other purpose which would make this credit a “purpose credit” within the meaning of Regulation U of the Board, or for any purpose that entails a violation of any
of the Regulations of the Board, including Regulations T, U and X All Loans and Letters of Credit will be used for business, commercial, investment, agricultural or other similar purpose and not for personal, family or household use.

deliver to the Administrative Agent on behalf of the Lenders a guaranty, in form and substance satisfactory to the Administrative Agent, duly authorized and executed by such Domestic Material Subsidiary, to the end that all Domestic Material
Subsidiaries shall at all times (to the extent set forth in each such Guaranty) guarantee the Obligations. In connection therewith, the Borrower shall deliver, and shall cause each such Domestic Material Subsidiary to deliver, to the Administrative
Agent with respect to each such Domestic Material Subsidiary all of the materials described in subsections (d) and (e) of Section 4.01 and all other agreements, documents, instruments and other writings as may be necessary or desirable
(in the opinion of the Administrative Agent) in connection with such guaranty.

the Equity 

  

 51 

 
Interests) in such Material Subsidiary to deliver, a security agreement and pledge, in form and substance satisfactory to the Administrative Agent, duly
authorized and executed by the Borrower and each such other owner or owners, together with any certificates evidencing such Equity Interests, and all necessary consents and approvals, to the end that all of the Equity Interests and related property
(or, in the case of a Material Subsidiary that is not a Domestic Material Subsidiary, not less than 65% of the Equity Interests and related property) in all Material Subsidiaries shall at all times secure the Obligations. In connection therewith,
the Borrower shall deliver, and shall cause each such owner or owners and each such Material Subsidiary to deliver, to the Administrative Agent with respect to such Material Subsidiary all of the materials described in clauses (d) and (e) of
Section 4.01 and all other such agreements, documents, instruments and other writings as may be necessary or desirable (in the opinion of the Administrative Agent) to create and perfect a valid first lien pledge of and security interest in
all such Equity Interests and related property.

and all financing statements, continuation statements, extension agreements and other documents, properly completed (and executed and acknowledged when required) by the appropriate Person, in form and substance satisfactory to the Administrative
Agent, which the Administrative Agent may in its discretion requests for the purpose of perfecting, confirming, or protecting any Liens or other rights in any Collateral at any time securing any Obligations. In addition to the foregoing, the
Borrower hereby authorizes, and shall cause each of its consolidated Subsidiaries to authorize, the Administrative Agent to file in the appropriate filing office pursuant to applicable Law such financing statements, assignments and continuation
statements as the Administrative Agent shall deem necessary or desirable for the purpose of perfecting, confirming, or protecting any Liens or other rights in the Collateral without the signature of the Borrower or any of its Subsidiaries.

will cause each of its Subsidiaries to, notify the Administrative Agent no later than the date on which the Borrower or any consolidated Subsidiary changes its jurisdiction of formation or organization, its name, the location of its chief executive
office or principal place of business, or the place where it keeps its books and records. The Borrower will notify the Administrative Agent no later than the date on which the Borrower or any of its consolidated Subsidiaries creates or acquires any

and, in the case of any event with respect to the Borrower described in clause (h) or (i) of this Section, the Commitments shall automatically terminate and the principal of the Loans then outstanding, together with all accrued and unpaid
interest thereon and all accrued and unpaid fees and all other accrued and unpaid Obligations of the Borrower and the other Obligors hereunder and under the other Loan Documents, shall automatically become due and payable, without presentment,
demand, protest or other notice of any kind, including but not limited to notice of intent to accelerate and notice of acceleration, all of which are hereby WAIVED by the Borrower, and thereupon the Administrative Agent may exercise any or all of
its rights referred to in clauses (iii) and (iv) above. 
  
 SECTION 7.02. Performance by the Agent, Etc. If the Borrower shall fail to perform any covenant or agreement in accordance with the terms of the Loan Documents, the 

  

 60 

 
Administrative Agent may (but shall not be obligated to) perform or attempt to perform, or may (but shall not be obligated to) cause any Lender (with the
consent of such Lender) to perform or attempt to perform, such covenant or agreement on behalf of the Borrower. In such event, the Borrower shall, at the request of the Administrative Agent, promptly pay any amount expended by the Administrative
Agent or the Lenders in connection with such performance or attempted performance to the Administrative Agent, together with interest thereon at the applicable Default Rate from and including the date of such expenditure to but excluding the date
such expenditure is paid in full. Notwithstanding the foregoing, it is expressly agreed that neither the Administrative Agent nor any Lender shall have any liability or responsibility for the performance of any obligation of the Borrower or any
other Person under this Agreement or any of the other Loan Documents. 
  
 ARTICLE VIII 
 The Administrative Agent 
  
 SECTION 8.01. Appointment and Powers. Each of the Lenders and the Issuing Bank 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. 
  
 SECTION 8.02. Rights as a
Lender. The lender 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 lender 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. 
  
 SECTION 8.03. Exculpation. 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 be responsible to any Lender for any recitals, statements, representations or warranties contained in this Agreement or any other Loan Document or in any writing furnished or provided by or
on behalf of the Borrower or any other Obligor pursuant to this Agreement or any other Loan Document, or in any certificate or other document referred to or provided for in, or received by it under, this Agreement or any other Loan Document, or for
the value, validity, effectiveness, genuineness, enforceability or sufficiency of this Agreement or any other Loan Document or any document referred to or provided for herein or therein, or any Property covered thereby or for any failure by the
Borrower or any other Person to perform any of its obligations hereunder or thereunder; (c) 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 (d) 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 

  

 61 

 
is communicated to or obtained by the lender 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 or inquire into (i) any statement, warranty or representation made in or in connection with this Agreement or any other Loan Document, (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 or any other Loan Document, (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. 
  
 SECTION 8.04. Reliance. 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. 
  
 SECTION 8.05. Performance Through Sub-Agents and Related Parties. 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. 
  
 SECTION
8.06. Resignation. Subject to the appointment and acceptance of a successor Administrative Agent as provided in this Section, the Administrative Agent may resign at any time by notifying the Lenders, the Issuing Bank and the Borrower. Upon
any such resignation, the Required Lenders shall have the right, with (unless a Default shall have occurred and be continuing) the consent of the Borrower, such consent not to be unreasonably withheld, 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, then the retiring Administrative Agent may, on behalf of the Lenders and
the Issuing Bank, and with (unless a Default shall have occurred and be continuing) the consent of the Borrower, such consent not to be unreasonably withheld, appoint a successor 

  

 62 

 
Administrative Agent. Any successor Administrative Agent shall be a bank that has an office in the United States of America and a combined capital and
surplus of at least $1,000,000,000 and with its deposits insured by the Federal Deposit Insurance Corporation. 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. 
  
 SECTION 8.07. Acknowledgements of Each Lender.
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 9.02. Waivers; Amendments. 
  
 (a) No waiver of any Default or Event of Default shall be a waiver of any other Default or Event of Default. No failure or
delay by the Administrative Agent, the Issuing Bank or any Lender in exercising any right or power hereunder or under any other Loan Document 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 Bank 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 any other Loan Document or consent to any departure by the Borrower or any other Obligor
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. No notice to
or demand on any Person shall entitle any Person to any or notice or demand in similar or other circumstances. 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 the Issuing Bank may have had notice or knowledge of such Default at the time. 
  
 (b) Neither this Agreement or any other Loan Document nor any provision hereof or thereof 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 the Commitment of any Lender without the written consent of such Lender, (ii) reduce the principal amount of any Loan or reimbursement obligation with respect to an 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 any reimbursement obligation with respect to an 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
2.18(b) or (c) in a manner that would alter the pro rata sharing of payments required thereby, without the written consent of each Lender, or (v) 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 no such agreement shall amend, modify or otherwise affect the rights or duties of the Administrative Agent or the Issuing Bank hereunder without the prior written consent of the Administrative Agent or the Issuing Bank, 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 its Affiliates, including the reasonable fees, charges and disbursements of counsel for the Administrative Agent, in connection with the syndication of the credit facilities provided
for herein, the preparation and administration of this Agreement and the other Loan Documents or any amendments, modifications or waivers of the provisions hereof or thereof (whether or not the transactions contemplated hereby or thereby shall be
consummated), 

  

 65 

 
(ii) all reasonable out-of-pocket expenses incurred by the Issuing Bank in connection with the issuance, amendment, renewal or extension of any Letter of
Credit or any demand for payment thereunder and (iii) all out-of-pocket expenses incurred by the Administrative Agent, the Issuing Bank or any Lender, including the fees, charges and disbursements of any counsel for the Administrative Agent, the
Issuing Bank or any Lender, in connection with the enforcement or protection of its rights in connection with this Agreement, including its rights under this Section, or in connection with any other Loan Document, or in connection with the Loans
made or Letters of Credit issued hereunder, including all such out-of-pocket expenses incurred during any workout, restructuring or negotiations in respect of such Loans or Letters of Credit. 
  
 (b) To the fullest extent permitted by law, the Borrower shall indemnify
the Administrative Agent, the Issuing Bank and 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, costs, and related expenses (including costs of investigation and defense, legal fees and amounts paid in settlement) to which any of them may become subject, regardless of and including losses, claims, damages,
liabilities, costs and expenses arising from the sole, ordinary or contributory negligence of the Person to be indemnified, 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, any of the other Loan Documents, or any agreement or instrument contemplated hereby or thereby, the performance by the parties hereto and the other Obligors of their respective obligations hereunder and under the other
Loan Documents 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 the Issuing Bank to honor a 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 in violation of any Environmental Law, or any Environmental Liability related in any way to the Borrower or any of its Subsidiaries, or (iv) any actual or prospective claim, litigation,
investigation or proceeding relating to any of the foregoing, whether based on contract, tort or any other theory and regardless of whether any Indemnitee is a party thereto; 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, illegal acts 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 the Issuing Bank under paragraph (a) or (b) of this Section, each Lender severally agrees to pay to the Administrative Agent or the 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 the Issuing Bank in its capacity as such. 
  

 66 

 (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 due not later than five Business Days after written demand therefor. 
  
 SECTION 9.04. Successors and Assigns. 
  
 (a) The provisions of this Agreement shall be binding upon and inure to the
benefit of the parties hereto and their respective successors and assigns permitted hereby (including any Affiliate of the Issuing Bank that issues any Letter 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 or in any other Loan Document, 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 Affiliate of the Issuing Bank that issues any Letter of Credit), Participants (to the extent provided in paragraph (c) of this Section) and, to the extent expressly contemplated hereby, the Related
Parties of each of the Administrative Agent, the Issuing Bank 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) and the other Loan Documents, with the prior written consent (such consent not to be
unreasonably withheld) of: 
  
 (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 (as defined below) or, if an Event of Default has occurred and is continuing, any other assignee; and

  
 (B) the Administrative Agent, provided
that no consent of the Administrative Agent shall be required for an assignment to an assignee that is a Lender immediately prior to giving effect to such assignment. 
  
 (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, 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 

  

 67 

 
$3,000,000 unless each of the Borrower and the Administrative Agent otherwise consent, 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. 
  
 For the purposes of this Section 9.04(b), the term “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 that administers or
manages a Lender. 
  
 (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 2.14, 2.15, 2.16 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 Bank 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 Bank 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 

  

 68 

 
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 Bank, 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) and the other Loan Documents;
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 Bank 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 and the other Loan Documents. 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 the other Loan Documents and to approve any amendment, modification or waiver of any provision
of this Agreement and the other Loan Documents; 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 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 2.14, 2.15 and 2.16 to the same
extent as if it were a Lender and had acquired its interest by assignment pursuant to paragraph (b) of this Section. To the extent permitted by law, each Participant also shall be entitled to the benefits of Section 9.08 as though it
were a Lender, provided such Participant agrees to be subject to Section 2.18(c) as though it were a Lender. 
  
 (ii) A Participant shall not be entitled to receive any greater payment under Section 2.14, 2.15 or 2.16 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. A Participant that would be a Foreign Lender if it were
a Lender shall not be entitled to the benefits of Section 2.16 unless the Borrower is notified of the participation sold to such Participant and such Participant agrees, for the benefit of the Borrower, to comply with Section 2.16(e)
as though it were a Lender. 
  
 (d) Any Lender may at any time
pledge or assign a security interest in all or any portion of its rights under this Agreement and the other Loan Documents to secure obligations of such Lender, including 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. 
  
 (e) Any
Lender may, in connection with any assignment or participation or proposed assignment or participation pursuant to this Section, disclose to the assignee or participant or 

  

 69 

 
proposed assignee or participant any information relating to the Borrower or any Subsidiary furnished to such Lender by or on behalf of the Borrower or such
Subsidiary. 
  
 SECTION 9.05. Survival. All covenants,
agreements, representations and warranties made by or on behalf of the Borrower or any other Obligor in connection with this Agreement or any of the other Loan Documents or in any certificate or other instrument 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 other Loan Documents and the making of any Loans and the issuance of any
Letter of Credit, regardless of any investigation made by any such other party or on its behalf and notwithstanding that the Administrative Agent, the 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 Obligations under this Agreement or any of
the other Loan Documents is outstanding and unpaid, any LC Exposure exists, or the Commitments have not expired or terminated. The provisions of Sections 2.14, 2.15, 2.16 and 9.03 and Article VIII shall survive and remain in
full force and effect regardless of the consummation of the Transactions, the repayment of the Loans and the other Obligations, 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. Payments Set Aside. To
the extent that the Borrower or any other Obligor makes a payment to any Lender, or any Lender exercises its right of set-off, or recovers any amount from the Collateral, and such payment or the proceeds of such set-off or Collateral, or any part
thereof, is subsequently invalidated, declared to be fraudulent or preferential, set aside or required (including pursuant to any settlement entered into by any Lender in its discretion) to be repaid to a trustee, receiver or any other party, in
connection with any proceeding under any bankruptcy or insolvency law or otherwise, then, to the extent of such recovery, the obligation or part thereof originally intended to be satisfied shall be revived and continued in full force and effect as
if such payment had not been made or such set-off had not occurred. 
  
 SECTION 9.07. Counterparts; Integration. 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. Loan Documents may be transmitted and/or signed by facsimile, and the effectiveness of such documents and signatures shall, subject to applicable Law, have the same force and effect as manually signed originals
and shall be binding on the parties hereto. This Agreement and the other Loan Documents together with 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. This Agreement once effective shall be binding upon and inure to the benefit of the parties hereto
and their respective successors and assigns. 
  
 SECTION 9.08.
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 

  

 70 

 
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 9.09. 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 the Borrower against any of and all the obligations of
the Borrower now or hereafter existing under this Agreement held by such Lender, irrespective of whether or not such Lender shall have made any demand under this Agreement 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 9.10. Governing Law; Jurisdiction; Consent to Service of Process. 
  
 (a) This Agreement and all other Loan Documents shall be construed in accordance with and governed by the law of the
State of Texas without giving effect to its conflicts of law principles. 
  
 (b) The Borrower hereby irrevocably and unconditionally submits, for itself and its Property, to the nonexclusive jurisdiction of the District Courts of the State of Texas sitting in Harris County and of the United
States District Court for the Southern District of Texas, Houston Division, and any appellate court from any thereof, in any action or proceeding arising out of or relating to this Agreement or the other Loan Documents, or the Transactions, or for
recognition or enforcement of any judgment, and each of the parties hereto hereby irrevocably and unconditionally agrees that all claims in respect of any such action or proceeding may be heard and determined in such Texas state or, to the extent
permitted by law, in such Federal court. Each of the parties hereto agrees that a final judgment in any such action or proceeding shall be conclusive and may be enforced in other jurisdictions by suit on the judgment or in any other manner provided
by law. Nothing in this Agreement shall affect any right that the Administrative Agent, the Issuing Bank or any Lender may otherwise have to bring any action or proceeding relating to this Agreement or any other Loan Document or the Transactions
against the Borrower or any other Obligor or any of their respective Properties in the courts of any jurisdiction. 
  
 (c) The Borrower hereby irrevocably and unconditionally waives, to the fullest extent it may legally and effectively do so, any objection which it may
now or hereafter have to the laying of venue of any suit, action or proceeding arising out of or relating to this Agreement or any other Loan Document or the Transactions in any court referred to in paragraph (b) of this Section. Each of the
parties hereto hereby irrevocably waives, to the fullest extent permitted by law, the defense of an inconvenient forum to the maintenance of such action or proceeding in any such court. 
  
 (d) Nothing herein shall be considered a waiver of the right or protections
afforded Bank by 12 U.S.C. 91, Article 59.007 of the Texas Finance Code, or any similar statute. 
  

 71 

 (e) Each party agrees that any other party may proceed against any other liable Person, jointly or
severally, or against one or more of them, less than all, without impairing rights against any other liable Persons. A party shall not be required to join the principal obligor or any other Person (e.g., sureties or guarantors) in any proceeding
against any Person. A party may release or settle with one or more liable Persons as the party deems fit without releasing or impairing right to proceed against any Persons not so released. 
  
 (f) Each party to this Agreement irrevocably consents to service of process
in the manner provided for notices in Section 9.01. Nothing in this Agreement will affect the right of any party to this Agreement to serve process in any other manner permitted by law. 
  
 SECTION 9.11. WAIVER OF JURY TRIAL. EACH PARTY HERETO HEREBY WAIVES,
TO THE FULLEST EXTENT PERMITTED BY APPLICABLE LAW, ANY RIGHT IT MAY HAVE TO A TRIAL BY JURY IN ANY LEGAL PROCEEDING DIRECTLY OR INDIRECTLY ARISING OUT OF OR RELATING TO THIS AGREEMENT OR ANY OTHER LOAN DOCUMENT OR ANY OF THE TRANSACTIONS
CONTEMPLATED HEREBY OR THEREBY (WHETHER BASED ON CONTRACT, TORT OR ANY OTHER THEORY). EACH PARTY HERETO (A) CERTIFIES THAT NO REPRESENTATIVE, AGENT OR ATTORNEY OF ANY OTHER PARTY HAS REPRESENTED, EXPRESSLY OR OTHERWISE, THAT SUCH OTHER PARTY WOULD
NOT, IN THE EVENT OF LITIGATION, SEEK TO ENFORCE THE FOREGOING WAIVER AND (B) ACKNOWLEDGES THAT IT AND THE OTHER PARTIES HERETO HAVE BEEN INDUCED TO ENTER INTO THIS AGREEMENT BY, AMONG OTHER THINGS, THE MUTUAL WAIVERS AND CERTIFICATIONS IN THIS
SECTION. 
  
 SECTION 9.12. 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 9.13. No Duty. All attorneys, accountants, appraisers, and
other professional Persons and consultants retained by the Administrative Agent and the Lenders shall have the right to act exclusively in the interest of the Administrative Agent and the Lenders and shall have no duty of disclosure, duty of
loyalty, duty of care, or other duty or obligation of any type or nature whatsoever to the Borrower or any Subsidiary or any of their respective Affiliates or any other Person. 
  
 SECTION 9.14. No Fiduciary Relationship. The relationship between the Borrower and each Lender is solely that of
debtor and creditor, and neither the Administrative Agent nor any Lender has any fiduciary or other special relationship to the Borrower or any Subsidiary or any of their respective Affiliates, and no term, provision, or condition of any of the Loan
Documents shall be construed so as to deem the relationship between the Borrower and any Lender, between any Subsidiary and any Lender, or between any such Affiliate and any Lender to be other than that of debtor and creditor. No joint venture or
partnership is created by this Agreement among the Lenders or among the Borrower, or any Subsidiary, or any of their respective Affiliates, and the Lenders. 
  

 72 

 SECTION 9.15. Construction. The Borrower, the Administrative Agent, and each Lender acknowledges
that it has had the benefit of legal counsel of its own choice and has been afforded an opportunity to review this Agreement and the other Loan Documents with its legal counsel and that this Agreement and the other Loan Documents shall be construed
as if jointly drafted by the parties hereto. 
  
 SECTION 9.16.
Independence of Covenants. All covenants hereunder shall be given independent effect so that if a particular action or condition is not permitted by any of such covenants, the fact that it would be permitted by an exception to, or be
otherwise within the limitations of, another covenant shall not avoid the occurrence of a Default if such action is taken or such condition exists. 
  
 SECTION 9.17. Confidentiality. Each of the Administrative Agent, the Issuing Bank 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, legal counsel and other advisors (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, (c) to the extent required by applicable
laws or regulations or by any subpoena or similar legal process, (d) to any other party to this Agreement or any other Loan Document, (e) in connection with the exercise of any remedies hereunder or under any other Loan Document, or any suit, action
or proceeding relating to this Agreement or any other Loan Document or the enforcement of rights hereunder or thereunder, (f) subject to an agreement containing provisions substantially the same as those of this Section, 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 or any other Loan Document, or (ii) any actual or prospective counterparty (or its advisors) in connection with a pledge pursuant
to any swap or derivative transaction relating to the Borrower and its obligations, (g) to any Federal Reserve Bank, or (h) to the extent such Information (i) becomes publicly available other than as a result of a breach of this Section or (ii)
becomes available to the Administrative Agent, the Issuing Bank or any Lender on a nonconfidential basis from a source other than the Borrower. For the purposes of this Section, “Information” means all information received from the
Borrower or any of its Subsidiaries relating to the Borrower, any Subsidiary or any of their respective businesses, other than any such information that is available to the Administrative Agent, the Issuing Bank or any Lender on a nonconfidential
basis prior to disclosure by the Borrower or such Subsidiary; provided that, in the case of information received from the Borrower or a Subsidiary after the date hereof, such information is clearly identified at the time of delivery as
confidential. Any Person required to maintain the confidentiality of Information as provided in this Section shall be considered to have complied with its obligation to do so if such Person has exercised the same degree of care to maintain the
confidentiality of such Information as such Person would accord to its own confidential information. 
  
 SECTION 9.18. Limitation of Interest. The parties to the Loan Documents intend to strictly comply with all applicable laws, including applicable
usury laws. Accordingly, the provisions of this Section 9.18 shall govern and control over every other provision of any Loan Document which conflicts or is inconsistent with this Section 9.18, even if such provision declares that it
controls. As used in this Section 9.18, the term “interest” includes the aggregate 

  

 73 

 
of all charges, fees, benefits or other compensation which constitute interest under applicable law; provided that, to the maximum extent permitted by
applicable law, (a) any non-principal payment shall be characterized as an expense or as compensation for something other than the use, forbearance or detention of money and not as interest and (b) all interest at any time contracted for, taken,
reserved, retained, charged, collected or received shall be amortized, prorated, allocated and spread during the full term of the Loans and the Commitments. In no event shall the Borrower or any other Person be obligated to pay, or any Lender have
any right or privilege to reserve, take, receive, collect or retain, any interest in excess of the maximum amount of nonusurious interest permitted under applicable law. None of the terms and provisions contained in any Loan Document which directly
or indirectly relate to interest shall ever be construed without reference to this Section 9.18, or be construed to create a contract to pay for the use, forbearance or detention of money at an interest rate in excess of the Maximum Rate On
each day, if any, that the interest rate (the “Stated Rate”) called for under any Loan Document exceeds the Maximum Rate, the rate at which interest shall accrue shall automatically be fixed by operation of this sentence at the
Maximum Rate for that day, and shall remain fixed at the Maximum Rate for each day thereafter until the total amount of interest accrued equals the total amount of interest which would have accrued if there were no such ceiling rate as imposed by
this sentence. Thereafter, interest shall accrue at the Stated Rate unless and until the Stated Rate again exceeds the Maximum Rate, whereupon the provisions of the immediately preceding sentence shall again automatically operate to limit the
interest accrual rate. The daily interest rates to be used in calculating interest at the Maximum Rate shall be determined by dividing the applicable Maximum Rate per annum by the number of days in the calendar year for which such calculation is
being made. If the term of any of the Loans is shortened by reason of acceleration of maturity as a result of any Default or by any other cause, or by reason of any required or permitted prepayment, and if for that (or any other) reason any Lender
at any time, including the stated maturity, is owed or receives, collects, reserves or takes (and/or has received, collected, reserved or taken) interest in excess of interest calculated at the Maximum Rate, then and in any such event all of any
such excess interest shall be canceled automatically as of the date of such acceleration, prepayment or other event which produces the excess, and, if such excess interest has been paid to such Lender, it shall be credited pro tanto against
the then-outstanding principal balance of the Borrower’s obligations to such Lender, effective as of the date or dates when the event occurs which causes it to be excess interest, until such excess is exhausted or all of such principal has been
fully paid and satisfied, whichever occurs first, and any remaining balance of such excess shall be promptly refunded to its payor.

 Disclosed Matters 
  
 In accordance with the definitions and text on pages 39 and 40 relating to Litigation
(Section 3.06), the extent of disclosure relating to Disclosures already made public in the Company’s filing of its 2001 10K as follows: 
  

	(9)	Commitments and Contingencies 

  
 Legal proceedings: A class action complaint was filed in the United States District Court for the Eastern District of Texas on March 7, 1997, by an
employee and a former employee which alleged race discrimination in employment. Certification hearings were conducted in Beaumont, Texas in February of 1998 and in Lufkin, Texas in August of 1998. The District Court in April of 1999 issued a
decision that certified a class for this case, which includes all persons of a certain minority employed by the Company from March 6,1994, to the present. The Company appealed this class certification decision by the District Court to the 5th
Circuit United States Court of Appeals in New Orleans, Louisiana. This appeal was denied on June 23, 1999. 
  
 The Company is defending this action vigorously. Furthermore, the Company believes that the facts and the law in this action support its position and
is confident that it will prevail if this case is tried on merits. 
  
 To
my knowledge, there have been no material items of litigation that would cause Lufkn Industries, Inc. to be outside the scope of Section 3.06. Additionally, all litigation is reviewed quarterly with Lufkin Industries, Inc.’s external auditors,
Deloitte and Touche, and accordingly disclosed in the quarterly 10Q’s.

 FOR VALUE RECEIVED,
LUFKIN INDUSTRIES, INC. (“Maker”), a Texas corporation, promises to pay to the order of
                                        
             (“Payee”) at the office of JPMorgan Chase Bank at 712 Main Street, Houston, Harris County, Texas, acting as administrative agent (including its successors
in such capacity, the “Administrative Agent”) for Payee and the other lenders (together with Payee, collectively referred to herein as the “Lenders”) which are now or may hereafter become parties to the Credit
Agreement referred to below, or at such other place as the Administrative Agent may hereafter designate in writing, in immediately available funds and in lawful money of the United States of America, the principal sum of
                                        
                     AND NO/100THS DOLLARS
($                            ) (or the unpaid balance of all principal advanced against this note, if
that amount is less), on the dates and in the principal amounts provided in the Credit Agreement referred to below, and to pay interest on the unpaid principal balance of this note from time to time outstanding until maturity at the rate or rates
established pursuant to the terms of the Credit Agreement and interest on all past due amounts, both principal and accrued interest, on demand at the rate or rates provided for in the Credit Agreement. 
  
 Interest on the amount of each advance against this note shall be computed on
the amount of that advance and from the date it is made. 
  
 The
principal of this note shall be due and payable on the Maturity Date, the final maturity of this note. Accrued and unpaid interest shall be due and payable as provided in the Credit Agreement and at the maturity of this note. All payments shall be
applied first to accrued and unpaid interest, the balance to principal. 
  
 Subject to the provisions of the Credit Agreement, Maker may at any time pay the full amount or any part of this note without payment of any premium or fee. All prepayments shall be applied in accordance with the Credit Agreement.

  
 The unpaid principal balance of this note at any time shall be
the total of all principal lent or advanced against this note less the sum of all principal payments and permitted prepayments made on this note by or for the account of Maker. All loans and advances and all payments and permitted prepayments made
hereon may be endorsed by the holder of this note on the schedule which is attached hereto (and hereby made a part hereof for all purposes) or otherwise recorded in the holder’s records; provided that any failure to make notation of (a)
any advance shall not cancel, limit or otherwise affect Maker’s obligations or any holder’s rights, or (b) any payment or permitted prepayment of principal shall not cancel, limit or otherwise affect Maker’s entitlement to credit for
that payment as of the date received by the Administrative Agent. 
  

 Subject to the provisions of the Credit Agreement, Maker may use all or any part of the credit provided
to be evidenced by this note at any time during the Availability Period. Maker may borrow, repay and reborrow and there is no limit on the number of advances against this note so long as the total unpaid principal of this note at any time
outstanding does not exceed the lesser of (a) the face amount of this note or (b) the amount of Payee’s Commitment, all determined from time to time in accordance with the Credit Agreement. 
  
 This note is one of the Notes which have been issued pursuant to the terms of
that certain Credit Agreement dated as of December 30, 2002, among Maker, the Lenders party thereto, and JPMorgan Chase Bank, as Administrative Agent and as Issuing Bank, as amended, modified, supplemented and restated (the “Credit
Agreement”), to which reference is made for all purposes, and evidences Loans made by Payee thereunder. This note is governed by and entitled to the benefits of the Credit Agreement. Any term used in this note and defined in the Credit
Agreement shall have the meaning ascribed to it in the Credit Agreement. Advances against this note by Payee or other holder hereof shall be governed by the Credit Agreement. 
  
 The occurrence of an Event of Default shall constitute default under this note, whereupon the Administrative Agent or the
holder hereof shall be entitled to exercise any or all rights, powers and remedies afforded (a) under the Credit Agreement and (b) by applicable law, including the right to accelerate the maturity of this entire note. 
  
 If any holder of this note retains an attorney in connection with any such
default or to collect, enforce or defend this note or any papers intended to secure or guarantee it in any lawsuit or in any probate, reorganization, bankruptcy or other proceeding, or if Maker sues any holder in connection with this note or any
such papers and does not prevail, Maker agrees to pay to each such holder, in addition to principal and interest, all reasonable costs and expenses incurred by such holder in trying to collect this note or in any such suit or proceeding, including
reasonable attorneys’ fees. 
  
 THIS NOTE SHALL BE
GOVERNED BY AND CONSTRUED IN ACCORDANCE WITH THE LAWS OF THE STATE OF TEXAS WITHOUT GIVING EFFECT TO ANY CONFLICTS OF LAWS PRINCIPLES THAT WOULD REQUIRE THE APPLICATION OF THE LAWS OF ANOTHER JURISDICTION, AND THE FEDERAL LAWS OF THE UNITED STATES
OF AMERICA.
