BB&T Corporation

Merger Completion Incentive
Program - Summary

Under the Merger Completion Incentive Program (the “Incentive
Program”) adopted on June 23, 2015 by the Compensation Committee of the BB&T Corporation Board of Directors (the “Committee”),
an incentive may be paid to Executive Management upon the operational conversion of the Susquehanna Bank (“Susquehanna”
) banking operations into the Branch Banking and Trust Company (“BB&T”) banking operations. For purposes of the
Incentive Program, the “operational conversion” occurs at the time that BB&T’s computer systems replace Susquehanna’s
computer systems as the current and primary systems of record for the transactional and accounting data of Susquehanna. The occurrence
of the operational conversion shall be determined by the Committee. When making its determination the Committee may reduce Incentive
Program awards based on the Committee’s assessment of BB&T Corporation’s then current performance.

 

		1.	Incentive Program Participants and Eligible Amounts

For each Executive Manager, an “Eligible Amount”
was determined and is the maximum amount that may be awarded to the applicable Executive Manager under the Incentive Program upon
the operational conversion with Susquehanna. The Eligible Amount for each of the “Named Executive Officers” included
in the Summary Compensation Table of BB&T’s Proxy Statement for its 2015 Annual Meeting of Shareholders is set forth
on a Current Report on Form 8-K dated June 23, 2015 and is incorporated by reference herein.

 

		2.	Performance Period

The Incentive Program has a one-year performance period.
To receive the Eligible Amount, the operational conversion must occur on or after June 23, 2015, but on or before June 23, 2016.
The Eligible Amount will not be paid for the operational conversion occurring after June 23, 2016.

		3.	Payment 

Any award under this Incentive Program may be paid
to each Executive Manager in cash, restricted stock units, or a combination thereof, as determined by the Committee. Payment will
occur as soon as administratively practicable following the Committee’s determination that the operational conversion has
occurred and determination of the award amount. Any portion of an award paid in cash and earned in a calendar year shall be paid
to all Executive Managers no later than March 15 of the following calendar year. Any portion of an award paid in restricted stock
units shall be awarded in accordance with the BB&T Corporation 2012 Incentive plan. All Incentive Program payments paid in
cash are subject to regular tax withholdings and authorized deductions.

    	1

    	 

    

		4.	Termination of Employment

If an Executive Manager’s employment terminates
during the performance period, participation in the Incentive Program ends on the date of termination, and the Executive Manager
will no longer be eligible to receive any Incentive Program payments.

		5.	Authority of Compensation Committee

The Committee shall have the authority to determine
the amount of any awards under this Incentive Program, to construe and interpret the Incentive Program, to administer all aspects
of the Incentive Program, and, to the extent mandated by any statute, regulation, or formal or informal guidance issued by any
regulatory authority with jurisdiction over BB&T Corporation, to modify or terminate the Incentive Program. Any interpretation
of the Incentive Program by the Committee and any decision made by it with respect to the Incentive Program are final and binding
on all parties.

		6.	Governing Law

This Incentive Program shall be governed by and construed
in accordance with the laws of the State of North Carolina, without regard to the principles of conflicts of law, and in accordance
with applicable United States federal laws.

Section 2.1 Revolving Commitments. 

(a) Revolving Commitment. Each Lender severally agrees, on the terms and conditions set forth in this Agreement, to make Revolving
Advances to the Borrower from time to time on any Business Day during the period from the Effective Date until the Maturity Date; provided that after giving effect to such Revolving Advances, the Outstandings shall not exceed the aggregate
Revolving Commitments in effect at such time. Each Revolving Borrowing shall (A) if comprised of Base Rate Advances be in an aggregate amount not less than $100,000 and in integral multiples of $100,000 in excess thereof, (B) if comprised
of LIBOR Advances be in an aggregate amount not less than $200,000 and in integral multiples of $100,000 in excess thereof, and (C) consist of Revolving Advances of the same Type made on the same day by the Lenders ratably according to their
respective Revolving Commitments. Within the limits of each Lender’s Revolving Commitment, the Borrower may from time to time borrow, prepay pursuant to Section 2.5, and reborrow under this Section 2.1(a). 

(b) Reduction of the Commitments. 

(i) Revolving Commitments. The Borrower shall have the right, upon at least three Business Days’ irrevocable notice
to the Administrative Agent, to terminate in whole or reduce in part the unused portion of the Revolving Commitments; provided that each partial reduction shall be in a minimum amount of $200,000 and in integral multiples of $100,000 in
excess thereof. Other than as provided in Section 2.1(b)(ii) below, any reduction or termination of the Commitments pursuant to this Section 2.1(a)(i) shall be applied ratably to each Lender’s Revolving Commitment and shall be
permanent, with no obligation of the Lenders to reinstate such Revolving Commitments, and the Commitment Fees shall thereafter be computed on the basis of the aggregate Revolving Commitments, as so reduced. If there are no outstanding Revolving
Commitments, Letters of Credit, expenses, fees or any other amounts owing pursuant to any Credit Document, the Borrower shall have the right, upon at least one Business Day’s notice to the Administrative Agent, to terminate this Agreement
except the terms hereof which expressly state that such terms survive the termination of this Agreement or the termination of the Revolving Commitments. 

(ii) Defaulting Lender. At any time when a Lender is then a Defaulting Lender, the Borrower, at the Borrower’s
election, may terminate such Defaulting Lender’s Revolving Commitment hereunder; provided that (A) such termination must be of the Defaulting Lender’s entire Revolving Commitment, (B) the Borrower shall pay all amounts
owed by the Borrower to such Defaulting Lender in such Lender’s capacity as a Lender under this Agreement and under the other Credit Documents (including principal of and interest on the Revolving Advances owed to such Defaulting Lender,
accrued commitment fees (subject to Section 2.7(a)), and letter of credit fees but specifically excluding any amounts owing under Section 2.10 as result of such payment of Revolving Advances) and shall deposit with the Administrative Agent
into the Cash Collateral Account cash collateral in the amount equal to such Defaulting Lender’s ratable share of the Letter of Credit Exposure, (C) a Defaulting Lender’s Revolving Commitment may be terminated by the Borrower under
this Section 2.1(b)(ii) if and only if at such time, the Borrower has elected, or is then electing, to terminate the Revolving Commitments of all then existing Defaulting Lenders. Upon written notice to the Defaulting Lender and
Administrative Agent of the Borrower’s election to terminate a Defaulting Lender’s Revolving Commitment pursuant to this clause (ii) and the payment and deposit of amounts required to be made by the Borrower

  
 -21- 

 
under clause (B) above, (1) such Defaulting Lender shall cease to be a “Lender” hereunder for all purposes except that such Lender’s rights as a Lender under Sections
2.11, 2.13, 8.5 and 9.2 shall continue with respect to events and occurrences occurring before or concurrently with its ceasing to be a “Lender” hereunder, (2) such Defaulting Lender’s Revolving Commitment shall be deemed
terminated, and (3) such Defaulting Lender shall be relieved of its obligations hereunder as a “Lender”. 
 (c) Notes.
The indebtedness of the Borrower to each Lender resulting (i) from Revolving Advances owing to such Lender shall be evidenced by a Revolving Note and (ii) from Swing Line Advances owing to the Swing Line Lender, as set forth in
Section 2.3 below, shall be evidenced by a Swing Line Note. 
 Section 2.2 Letters of Credit  

(a) Commitment for Letters of Credit. Subject to the terms and conditions set forth in this Agreement, the Issuing Lender agrees, in
reliance upon the agreements of the other Lenders set forth in this Section 2.2, from time to time on any Business Day during the period from the Effective Date until the date that is 10 days prior to the Maturity Date, to issue, increase or
extend the expiration date of, Letters of Credit for the account of any Credit Party, provided that no Letter of Credit will be issued, increased, or extended: 

(i) if such issuance, increase, or extension would cause the Letter of Credit Exposure to exceed the lesser of (A) the
Letter of Credit Maximum Amount and (B) an amount equal to (1) the aggregate Revolving Commitments in effect at such time minus (2) the sum of the aggregate outstanding amount of all Revolving Advances plus the aggregate
outstanding amount of all Swing Line Advances; 
 (ii) unless such Letter of Credit has an expiration date not later than 10
days prior to the Maturity Date; provided that, if Revolving Commitments are terminated in whole pursuant to Section 2.1(b)(i), the Borrower shall, at its election, either (A) deposit into the Cash Collateral Account cash in an
amount equal to 105% of the Letter of Credit Exposure for the Letters of Credit which have an expiry date beyond the Maturity Date or (B) provide a replacement letter of credit (or other security) reasonably acceptable to the Administrative
Agent and the Issuing Lender in an amount equal to 105% of the Letter of Credit Exposure; 
 (iii) unless such Letter of
Credit is (A) a standby letter of credit not supporting the repayment of indebtedness for borrowed money of any Person, or (B) with the consent of the Issuing Lender (such consent not to be unreasonably withheld) and so long as the
Borrower as agreed to such additional reasonable fees which may apply, a commercial letter of credit; 
 (iv) unless such
Letter of Credit is in form and substance acceptable to the Issuing Lender in its sole discretion; 
 (v) unless the Borrower
has delivered to the Issuing Lender a completed and executed Letter of Credit Application; provided that, if the terms of any Letter of Credit Application conflicts with the terms of this Agreement, the terms of this Agreement shall control; 

(vi) unless such Letter of Credit is governed by (A) the Uniform Customs and Practice for Documentary Credits (2007
Revision), International Chamber of Commerce Publication No. 600, or (B) the International Standby Practices (ISP98), International Chamber of Commerce Publication No. 590, in either case, including any subsequent revisions thereof
approved by a Congress of the International Chamber of Commerce and adhered to by the Issuing Lender; 

  
 -22- 

 (vii) if any order, judgment or decree of any Governmental Authority or
arbitrator shall by its terms purport to enjoin or restrain the Issuing Lender from issuing, increasing or extending such Letter of Credit, or any Legal Requirement applicable to the Issuing Lender or any request or directive (whether or not having
the force of law) from any Governmental Authority with jurisdiction over the Issuing Lender shall prohibit, or request that the Issuing Lender refrain from, the issuance, increase or extension of letters of credit generally or such Letter of Credit
in particular or shall impose upon the Issuing Lender with respect to such Letter of Credit any restriction, reserve or capital requirement (for which the Issuing Lender is not otherwise compensated hereunder) not in effect on the Effective Date, or
shall impose upon the Issuing Lender any unreimbursed loss, cost or expense which was not applicable on the Effective Date and which the Issuing Lender in good faith deems material to it; 

(viii) if the issuance, increase or extension of such Letter of Credit would violate one or more policies of the Issuing Lender
applicable to letters of credit generally; 
 (ix) if Letter of Credit is to be denominated in a currency other than Dollars;
or 
 (x) any Lender is at such time a Defaulting Lender or a Potential Defaulting Lender hereunder, unless the Issuing
Lender has entered into satisfactory arrangements with the Borrower or such Lender to eliminate the Issuing Lender’s risk with respect to such Lender. 

Furthermore, anything contained herein to the contrary notwithstanding, the Issuing Lender may, but shall not be obligated to, issue or cause the issuance of
a Letter of Credit that supports the obligations of the Borrower or its Subsidiaries in respect of (1) a lease of real property, or (2) an employment contract. 

(b) Requesting Letters of Credit. Each Letter of Credit shall be issued pursuant to a Letter of Credit Application given by the
Borrower to the Administrative Agent for the benefit of the Issuing Lender by facsimile or other writing not later than 11:00 a.m. (Houston, Texas, time) on the third Business Day before the proposed date of issuance for the Letter of Credit. Each
Letter of Credit Application shall be fully completed and shall specify the information required therein. Each Letter of Credit Application shall be irrevocable and binding on the Borrower. Subject to the terms and conditions hereof, the Issuing
Lender shall before 2:00 p.m. (Houston, Texas, time) on the date of such Letter of Credit issue such Letter of Credit to the beneficiary of such Letter of Credit. 

(c) Reimbursements for Letters of Credit; Funding of Participations. 

(i) With respect to any Letter of Credit, in accordance with the related Letter of Credit Application, the Borrower agrees to
pay on demand to the Administrative Agent on behalf of the Issuing Lender an amount equal to any amount paid by the Issuing Lender under such Letter of Credit. Upon the Issuing Lender’s demand for payment under the terms of a Letter of Credit
Application, the Borrower may, with a written notice, request that the Borrower’s obligations to the Issuing Lender thereunder be satisfied with the proceeds of a Revolving Advance in the same amount (notwithstanding any minimum size or
increment limitations on individual Revolving Advances). If the Borrower does not make such request and does not otherwise make the payments demanded by the Issuing Lender as required under this Agreement or the Letter of Credit Application, then
the Borrower shall be deemed for all purposes of this Agreement to have requested such a Revolving Advance in the same amount and the transfer of the proceeds thereof to satisfy the Borrower’s obligations to the Issuing Lender, and the Borrower

  
 -23- 

 
hereby unconditionally and irrevocably authorizes, empowers, and directs the Lenders to make such Revolving Advance, to transfer the proceeds thereof to the Issuing Lender in satisfaction of such
obligations, and to record and otherwise treat such payments as a Revolving Advance to the Borrower. The Administrative Agent and each Lender may record and otherwise treat the making of such Revolving Borrowings as the making of a Revolving
Borrowing to the Borrower under this Agreement as if requested by the Borrower. Nothing herein is intended to release any of the Borrower’s obligations under any Letter of Credit Application, but only to provide an additional method of payment
therefor. The making of any Borrowing under this Section 2.2(c) shall not constitute a cure or waiver of any Default, other than the payment Default which is satisfied by the application of the amounts deemed advanced hereunder, caused by the
Borrower’s failure to comply with the provisions of this Agreement or the Letter of Credit Application. 
 (ii) Each
Lender (including the Lender acting as Issuing Lender) shall, upon notice from the Administrative Agent that the Borrower has requested or is deemed to have requested a Revolving Advance pursuant to Section 2.4 and regardless of whether
(A) the conditions in Section 3.2 have been met, (B) such notice complies with Section 2.4, or (C) a Default exists, make funds available to the Administrative Agent for the account of the Issuing Lender in an amount equal
to such Lender’s Revolving Pro Rata Share of the amount of such Revolving Advance not later than 1:00 p.m. on the Business Day specified in such notice by the Administrative Agent, whereupon each Lender that so makes funds available shall be
deemed to have made a Revolving Advance to the Borrower in such amount. The Administrative Agent shall remit the funds so received to the Issuing Lender. 

(iii) If any such Lender shall not have so made its Revolving Advance available to the Administrative Agent pursuant to this
Section 2.2, such Lender agrees to pay interest thereon for each day from such date until the date such amount is paid at the lesser of (A) the Federal Funds Rate for such day for the first three days and thereafter the interest rate
applicable to the Revolving Advance and (B) the Maximum Rate. Whenever, at any time after the Administrative Agent has received from any Lender such Lender’s Revolving Advance, the Administrative Agent receives any payment on account
thereof, the Administrative Agent will pay to such Lender its participating interest in such amount (appropriately adjusted, in the case of interest payments, to reflect the period of time during which such Lender’s Revolving Advance was
outstanding and funded), which payment shall be subject to repayment by such Lender if such payment received by the Administrative Agent is required to be returned. Each Lender’s obligation to make the Revolving Advance pursuant to this
Section 2.2 shall be absolute and unconditional and shall not be affected by any circumstance, including (1) any set-off, counterclaim, recoupment, defense or other right which such Lender or any other Person may have against the Issuing
Lender, the Administrative Agent or any other Person for any reason whatsoever; (2) the occurrence or continuance of a Default or the termination of the Revolving Commitments; (3) any breach of this Agreement by any Credit Party or any
other Lender; or (4) any other circumstance, happening or event whatsoever, whether or not similar to any of the foregoing. 
 (d)
Participations. Upon the date of the issuance or increase of a Letter of Credit under Section 2.2(a), the Issuing Lender shall be deemed to have sold to each other Lender and each other Lender shall have been deemed to have purchased
from the Issuing Lender a participation in the related Letter of Credit Obligations equal to such Lender’s Revolving Pro Rata Share at such date and such sale and purchase shall otherwise be in accordance with the terms of this Agreement. The
Issuing Lender shall promptly notify each such participant Lender by telex, telephone, or telecopy of each Letter of Credit issued or increased and the actual dollar amount of such Lender’s participation in such Letter of Credit. 

  
 -24- 

 (e) Obligations Unconditional. The obligations of the Borrower under this Agreement in
respect of each Letter of Credit shall be unconditional and irrevocable, and shall be paid strictly in accordance with the terms of this Agreement under all circumstances, notwithstanding the following circumstances: 

(i) any lack of validity or enforceability of any Letter of Credit Documents; 

(ii) any amendment or waiver of or any consent to departure from any Letter of Credit Documents; 

(iii) the existence of any claim, set-off, defense or other right which any Credit Party may have at any time against any
beneficiary or transferee of such Letter of Credit (or any Persons for whom any such beneficiary or any such transferee may be acting), the Issuing Lender, any Lender or any other person or entity, whether in connection with this Agreement, the
transactions contemplated in this Agreement or in any Letter of Credit Documents or any unrelated transaction; 
 (iv) any
statement or any other document presented under such Letter of Credit proving to be forged, fraudulent, invalid or insufficient in any respect or any statement therein being untrue or inaccurate in any respect to the extent the Issuing Lender would
not be liable therefor pursuant to the following paragraph (g); 
 (v) payment by the Issuing Lender under such Letter of
Credit against presentation of a draft or certificate which does not comply with the terms of such Letter of Credit; or 

(vi) any other circumstance or happening whatsoever, whether or not similar to any of the foregoing; 

provided, however, that nothing contained in this paragraph (e) shall be deemed to constitute a waiver of any remedies of the Borrower in
connection with the Letters of Credit. 
 (f) Prepayments of Letters of Credit. In the event that any Letter of Credit shall be
outstanding or shall be drawn and not reimbursed on or prior to the 5th Business Day prior to the Maturity Date, the Borrower shall pay to the Administrative Agent an amount equal to 105% of the
Letter of Credit Exposure allocable to such Letter of Credit, such amount to be due and payable on the 5th Business Day prior to the Maturity Date, and to be held in the Cash Collateral Account
and applied in accordance with paragraph (h) below. 
 (g) Liability of Issuing Lender. The Borrower assumes all risks of the
acts or omissions of any beneficiary or transferee of any Letter of Credit with respect to its use of such Letter of Credit. Neither the Issuing Lender nor any of its officers or directors shall be liable or responsible for: 

(i) the use which may be made of any Letter of Credit or any acts or omissions of any beneficiary or transferee in connection
therewith; 
 (ii) the validity, sufficiency or genuineness of documents, or of any endorsement thereon, even if such
documents should prove to be in any or all respects invalid, insufficient, fraudulent or forged; 

  
 -25- 

 (iii) payment by the Issuing Lender against presentation of documents which do
not comply with the terms of a Letter of Credit, including failure of any documents to bear any reference or adequate reference to the relevant Letter of Credit; or 

(iv) any other circumstances whatsoever in making or failing to make payment under any Letter of Credit (INCLUDING THE
ISSUING LENDER’S OWN NEGLIGENCE), 
 except that the Borrower shall have a claim against the Issuing Lender, and the Issuing Lender shall be liable
to, and shall promptly pay to, the Borrower, to the extent of any direct, as opposed to consequential, damages suffered by the Borrower which the Borrower proves were caused by (A) the Issuing Lender’s willful misconduct or gross
negligence in determining whether documents presented under a Letter of Credit comply with the terms of such Letter of Credit or (B) the Issuing Lender’s willful failure to make lawful payment under any Letter of Credit after the
presentation to it of a draft and certificate strictly complying with the terms and conditions of such Letter of Credit. In furtherance and not in limitation of the foregoing, the Issuing Lender may accept documents that appear on their face to be
in order, without responsibility for further investigation, regardless of any notice or information to the contrary. 
 (h) Cash
Collateral Account. 
 (i) If the Borrower is required to deposit funds in the Cash Collateral Account pursuant to
Sections 2.2(f), 2.2(i), 2.5(c), 7.2(b) or 7.3(b), then the Borrower and the Administrative Agent shall establish the Cash Collateral Account and the Borrower shall execute any documents and agreements, including the Administrative Agent’s
standard form assignment of deposit accounts, that the Administrative Agent reasonably requests in connection therewith to establish the Cash Collateral Account and grant the Administrative Agent an Acceptable Security Interest in such account and
the funds therein. The Borrower hereby pledges to the Administrative Agent and grants the Administrative Agent, for the ratable benefit of the Secured Parties, a security interest in the Cash Collateral Account, whenever established, all funds held
in the Cash Collateral Account from time to time, and all proceeds thereof as security for the payment of the Secured Obligations. 

(ii) Funds held in the Cash Collateral Account shall be held as cash collateral for obligations with respect to Letters of
Credit and promptly applied by the Administrative Agent at the request of the Issuing Lender to any reimbursement or other obligations under Letters of Credit that exist or occur. To the extent that any surplus funds are held in the Cash Collateral
Account above the Letter of Credit Exposure during the existence of an Event of Default the Administrative Agent may (A) hold such surplus funds in the Cash Collateral Account as cash collateral for the Secured Obligations or (B) apply
such surplus funds to any Secured Obligations in any manner directed by the Majority Lenders. If no Default exists, the Administrative Agent shall release any surplus funds held in the Cash Collateral Account above the Letter of Credit Exposure to
the Borrower promptly following the Borrower’s written request. Notwithstanding the foregoing, if the Borrower has complied with the terms of Section 2.2(i) and no Default exists, or would result therefrom, the Administrative Agent shall
release the funds deposited by the Borrower pursuant to Section 2.2(i) to the Borrower promptly following the Borrower’s written request. 

(iii) Funds held in the Cash Collateral Account may be invested (for the benefit of the Borrower) in Liquid Investments
maintained with, and under the sole dominion and control of, the Administrative Agent or in another investment if mutually agreed upon by the Borrower and the Administrative Agent, but the Administrative Agent shall have no obligation to make any
investment of the funds therein. The Administrative Agent shall exercise reasonable care in the 

  
 -26- 

 
custody and preservation of any funds held in the Cash Collateral Account and shall be deemed to have exercised such care if such funds are accorded treatment substantially equivalent to that
which the Administrative Agent accords its own property, it being understood that the Administrative Agent shall not have any responsibility for taking any necessary steps to preserve rights against any parties with respect to any such funds. 

(i) Defaulting Lender. If, at any time, a Defaulting Lender or a Potential Defaulting Lender exists hereunder, then, at the request of
the Issuing Lender, the Borrower shall deposit funds with Administrative Agent into the Cash Collateral Account an amount equal to such Defaulting Lender’s or Potential Defaulting Lender’s pro rata share of the Letter of Credit Exposure.

 (j) Letters of Credit Issued for Guarantors or any Subsidiary. Notwithstanding that a Letter of Credit issued or outstanding
hereunder is in support of any obligations of, or is for the account of, a Guarantor or any Subsidiary, the Borrower shall be obligated to reimburse the Issuing Lender hereunder for any and all drawings under such Letter of Credit issued hereunder
by the Issuing Lender. The Borrower hereby acknowledges that the issuance of Letters of Credit for the account of any Guarantor, the Borrower or any Subsidiary inures to the benefit of the Borrower, and that the Borrower’s business (indirectly
or directly) derives substantial benefits from the businesses of such other Persons. 
 Section 2.3 Swing Line Advances. 

(a) Facility. On the terms and conditions set forth in this Agreement, and if an AutoBorrow Agreement is in effect, subject to the
terms and conditions of such AutoBorrow Agreement, the Swing Line Lender may, in its sole discretion, from time-to-time on any Business Day during the period from the date of this Agreement until the last Business Day occurring before the Maturity
Date, make Swing Line Advances under the Swing Line Note to the Borrower which shall be due and payable on the Swing Line Payment Date (except that no Swing Line Advance may mature after the Maturity Date), bearing interest at the Adjusted Base Rate
plus the Applicable Margin for Base Rate Advances, and in an aggregate outstanding principal amount not to exceed the Swing Line Sublimit Amount at any time; provided that (i) after giving effect to such Swing Line Advance, the
Outstandings shall not exceed the aggregate Revolving Commitments in effect at such time; (ii) no Swing Line Advance shall be made by the Swing Line Lender if the conditions set forth in Section 3.2 have not been met as of the date of such
Swing Line Advance, it being agreed by the Borrower that the giving of the applicable Notice of Borrowing and the acceptance by the Borrower of the proceeds of such Swing Line Advance shall constitute a representation and warranty by the Borrower
that on the date of such Swing Line Advance such conditions have been met; and (iii) if an AutoBorrow Agreement is in effect, such additional terms and conditions of such AutoBorrow Agreement shall have been satisfied, and in the event that any
of the terms of this Section 2.3(a) conflict with such AutoBorrow Agreement, the terms of the AutoBorrow Agreement shall govern and control. The indebtedness of the Borrower to the Swing Line Lender resulting from Swing Line Advances shall be
evidenced by the Swing Line Note. No Lender shall have any rights or obligations under any AutoBorrow Agreement, but each Lender shall have the obligation to purchase and fund risk participations in the Swing Line Advances and to refinance Swing
Line Advances as provided below. 
 (b) Prepayment. Within the limits expressed in this Agreement, amounts advanced pursuant to
Section 2.3(a) may from time to time be borrowed, prepaid without penalty, and reborrowed. If the aggregate outstanding principal amount of the Swing Line Advances ever exceeds the Swing Line Sublimit Amount, the Borrower shall, upon receipt of
written notice of such condition from the Swing Line Lender and to the extent of such excess, prepay to the Swing Line Lender outstanding principal of the Swing Line Advances such that such excess is eliminated. If an AutoBorrow Agreement is in
effect, each prepayment of a Swing Line Borrowing shall be made as provided in such AutoBorrow Agreement. 

  
 -27- 

 (c) Reimbursements for Swing Line Obligations. 

(i) With respect to the Swing Line Advances and the interest, premium, fees, and other amounts owed by the Borrower to the
Swing Line Lender in connection with the Swing Line Advances, the Borrower agrees to pay to the Swing Line Lender such amounts when due and payable to the Swing Line Lender under the terms of this Agreement and, if an AutoBorrow Agreement is in
effect, in accordance with the terms of such AutoBorrow Agreement. If the Borrower does not pay to the Swing Line Lender any such amounts when due and payable to the Swing Line Lender, the Swing Line Lender may upon notice to the Administrative
Agent request the satisfaction of such obligation by the making of a Revolving Borrowing in the amount of any such amounts not paid when due and payable. Upon such request, the Borrower shall be deemed to have requested the making of a Revolving
Borrowing in the amount of such obligation and the transfer of the proceeds thereof to the Swing Line Lender. Such Revolving Borrowing shall bear interest based upon the Adjusted Base Rate plus the Applicable Margin for Base Rate Advances. The
Administrative Agent shall promptly forward notice of such Revolving Borrowing to the Borrower and the Lenders, and each Lender shall, regardless of whether (A) the conditions in Section 3.2 have been met, (B) such notice complies
with Section 2.4, or (C) a Default exists, make available such Lender’s ratable share of such Revolving Borrowing to the Administrative Agent, and the Administrative Agent shall promptly deliver the proceeds thereof to the Swing Line
Lender for application to such amounts owed to the Swing Line Lender. The Borrower hereby unconditionally and irrevocably authorizes, empowers, and directs the Swing Line Lender to make such requests for Revolving Borrowings on behalf of the
Borrower, and the Lenders to make Revolving Advances to the Administrative Agent for the benefit of the Swing Line Lender in satisfaction of such obligations. The Administrative Agent and each Lender may record and otherwise treat the making of such
Revolving Borrowings as the making of a Revolving Borrowing to the Borrower under this Agreement as if requested by the Borrower. Nothing herein is intended to release the Borrower’s obligations under the Swing Line Note, but only to provide an
additional method of payment therefor. The making of any Borrowing under this Section 2.3(c) shall not constitute a cure or waiver of any Default or Event of Default, other than the payment Default or Event of Default which is satisfied by the
application of the amounts deemed advanced hereunder, caused by the Borrower’s failure to comply with the provisions of this Agreement or the Swing Line Note. 

(ii) If at any time, the Revolving Commitments shall have expired or be terminated while any Swing Line Advance is outstanding,
each Lender, at the sole option of the Swing Line Lender, shall either (A) notwithstanding the expiration or termination of the Revolving Commitments, make a Revolving Advance as a Base Rate Advance, or (B) be deemed, without further
action by any Person, to have purchased from the Swing Line Lender a participation in such Swing Line Advance, in either case in an amount equal to the product of such Lender’s Revolving Pro Rata Share times the outstanding aggregate principal
balance of the Swing Line Advances. The Administrative Agent shall notify each such Lender of the amount of such Revolving Advance or participation, and such Lender will transfer to the Administrative Agent for the account of the Swing Line Lender
on the next Business Day following such notice, in immediately available funds, the amount of such Revolving Advance or participation. 

(iii) If any such Lender shall not have so made its Revolving Advance or its percentage participation available to the
Administrative Agent pursuant to this Section 2.3, such Lender agrees to pay interest thereon for each day from such date until the date such amount is paid at the lesser of (A) the Federal Funds Rate for such day for the first three days
and thereafter the interest rate applicable to the Revolving Advance and (B) the Maximum Rate. Whenever, at any time after the Administrative Agent has received from any Lender such Lender’s Revolving

  
 -28- 

 
Advance or participating interest in a Swing Line Advance, the Administrative Agent receives any payment on account thereof, the Administrative Agent will pay to such Lender its participating
interest in such amount (appropriately adjusted, in the case of interest payments, to reflect the period of time during which such Lender’s Revolving Advance or participating interest was outstanding and funded), which payment shall be subject
to repayment by such Lender if such payment received by the Administrative Agent is required to be returned. Each Lender’s obligation to make the Revolving Advance or purchase such participating interests pursuant to this
Section 2.3 shall be absolute and unconditional and shall not be affected by any circumstance, including (1) any set-off, counterclaim, recoupment, defense or other right which such Lender or any other Person may have against the
Swing Line Lender, the Administrative Agent or any other Person for any reason whatsoever; (2) the occurrence or continuance of a Default or the termination of the Revolving Commitments; (3) any breach of this Agreement by the Borrower or
any other Lender; or (4) any other circumstance, happening or event whatsoever, whether or not similar to any of the foregoing. Each Swing Line Advance, once so participated by any Lender, shall cease to be a Swing Line Advance with respect to
that amount for purposes of this Agreement, but shall continue to be a Revolving Loan. 
 (d) Method of Borrowing. If an AutoBorrow
Agreement is in effect, each Swing Line Borrowing shall be made as provided in such AutoBorrow Agreement. Otherwise, and except as provided in the clause (c) above, each request for a Swing Line Advance shall be made pursuant to telephone
notice to the Swing Line Lender given no later than 1:00 p.m. (Houston, Texas time) on the date of the proposed Swing Line Advance, promptly confirmed by a completed and executed Notice of Borrowing telecopied or facsimiled to the Administrative
Agent and the Swing Line Lender. The Swing Line Lender will promptly make the Swing Line Advance available to the Borrower at the Borrower’s account with the Administrative Agent. 

(e) Interest for Account of Swing Line Lender. Swing Line Lender shall be responsible for invoicing the Borrower for interest on the
Swing Line Advances (provided that any failure of the Swing Line Lender to provide such invoice shall not release the Borrower from its obligation to pay such interest). Until each Lender funds its Revolving Advance or risk participation
pursuant to clause (c) above, interest in respect of Lender’s Revolving Pro Rata Share of the Swing Line Advances shall be solely for the account of the Swing Line Lender. 

(f) Payments Directly to Swing Line Lenders. The Borrower shall make all payments of principal and interest in respect of the Swing
Line Advances directly to the Swing Line Lender. 
 (g) Discretionary Nature of the Swing Line Facility. Notwithstanding any terms to
the contrary contained herein or in any AutoBorrow Agreement, the Swing Line facility provided herein or in any AutoBorrow Agreement (i) is an uncommitted facility and the Swing Line Lender may, but shall not be obligated to, make Swing Line
Advances, and (ii) may be terminated at any time by the Swing Line Lender upon written notice to the Borrower. 
 Section 2.4

Borrowing is to be comprised of LIBOR Advances, Interest Period for each such Advance. In the case of a proposed Borrowing comprised of LIBOR Advances, the Administrative Agent shall promptly notify each Lender of the applicable interest rate under
Section 2.8(b). Each Lender shall, before 12:00 noon (Houston, Texas time) on the date of such Borrowing, make available for the account of its applicable Lending Office to the Administrative Agent at its address referred to in
Section 9.9, or such other location as the Administrative Agent may specify by notice to the Lenders, in same day funds, such Lender’s Revolving Pro Rata Share of such Borrowing. After the Administrative Agent’s receipt of such funds
and upon fulfillment of the applicable conditions set forth in Article 3, the Administrative Agent will make such funds available to the Borrower at its account with the Administrative Agent or as otherwise directed by the Borrower with written
notice to the Administrative Agent. 
 (b) Conversions and Continuations. In order to elect to Convert or continue a Revolving
Advance under this paragraph, the Borrower shall deliver an irrevocable Notice of Continuation or Conversion to the Administrative Agent at the Administrative Agent’s office no later than 11:00 a.m. (Houston, Texas time) (i) on the
Business Day before the date of the proposed conversion date in the case of a Conversion to a Base Rate Advance and (ii) at least three Business Days in advance of the proposed Conversion or continuation date in the case of a Conversion to, or
a continuation of, a LIBOR Advance. Each such Notice of Conversion or Continuation shall be in writing or by telex or facsimile confirmed promptly by the Borrower with a hard copy (other than with respect to notice sent by facsimile), specifying
(i) the requested Conversion or continuation date (which shall be a Business Day), (ii) the amount, Type, and Class of the Advance to be Converted or continued, (iii) whether a Conversion or continuation is requested and, if a
Conversion, into what Type of Advance, and (iv) in the case of a Conversion to, or a continuation of, a LIBOR Advance, the requested Interest Period. Promptly after receipt of a Notice of Conversion or Continuation under this paragraph, the
Administrative Agent shall provide each Lender with a copy thereof and, in the case of a Conversion to or a Continuation of a LIBOR Advance, notify each Lender of the applicable interest rate under Section 2.8(b). The portion of Advances
comprising part of the same Borrowing that are converted to Advances of another Type shall constitute a new Borrowing. 
 (c) Certain
Limitations. Notwithstanding anything in paragraphs (a) and (b) above: 
 (i) at no time shall there be more
than five Interest Periods applicable to outstanding LIBOR Advances; 
 (ii) the Borrower may not select LIBOR Advances for
any Borrowing at any time when a Default has occurred and is continuing; 
 (iii) if any Lender shall, at least one Business
Day before the date of any requested Borrowing, notify the Administrative Agent that the introduction of or any change in or in the interpretation of any law or regulation makes it unlawful, or that any central bank or other governmental authority
asserts that it is unlawful, for such Lender or its applicable Lending Office to perform its obligations under this Agreement to make LIBOR Advances or to fund or maintain LIBOR Advances, (A) the obligation of such Lender to make such LIBOR Advance
as part of the requested Borrowing or for any subsequent Borrowing shall be suspended until such Lender shall notify the Borrower that the circumstances causing such suspension no longer exist and such Lender’s portion of such requested
Borrowing or any subsequent Borrowing of LIBOR Advances shall be made in the form of a Base Rate Advance, and (B) such Lender agrees to use commercially reasonable efforts (consistent with its internal policies and legal and regulatory
restrictions) to designate a different Lending Office if the making of such designation would avoid the effect of this paragraph and would not, in the reasonable judgment of such Lender, be otherwise disadvantageous to such Lender; 

  
 -30- 

 (iv) if the Administrative Agent is unable to determine the LIBO Rate for LIBOR
Advances comprising any requested Borrowing, the right of the Borrower to select LIBOR Advances for such Borrowing or for any subsequent Borrowing shall be suspended until the Administrative Agent shall notify the Borrower and the Lenders that the
circumstances causing such suspension no longer exist, and each Advance comprising such Borrowing shall be a Base Rate Advance; 

(v) if the Majority Lenders shall, at least one Business Day before the date of any requested Borrowing, notify the
Administrative Agent that the LIBO Rate for LIBOR Advances comprising such Borrowing will not adequately reflect the cost to such Lenders of making or funding their respective LIBOR Advances, as the case may be, for such Borrowing, the right of the
Borrower to select LIBOR Advances for such Borrowing or for any subsequent Borrowing shall be suspended until the Administrative Agent shall notify the Borrower and the Lenders that the circumstances causing such suspension no longer exist, and each
Advance comprising such Borrowing shall be a Base Rate Advance; and 
 (vi) if the Borrower shall fail to select the duration
or continuation of any Interest Period for any LIBOR Advances in accordance with the provisions contained in the definition of Interest Period in Section 1.1 and paragraph (b) above, the Administrative Agent will forthwith so notify the
Borrower and the Lenders and such Advances will be made available to the Borrower on the date of such Borrowing as Base Rate Advances or, if an existing Advance, Convert into Base Rate Advances. 

(d) Notices Irrevocable. Each Notice of Borrowing and Notice of Continuation or Conversion delivered by the Borrower hereunder,
including its deemed request for borrowing made under Section 2.2(c), shall be irrevocable and binding on the Borrower. 
 (e)
Administrative Agent Reliance. Unless the Administrative Agent shall have received notice from a Lender before the date of any Revolving Borrowing that such Lender will not make available to the Administrative Agent such Lender’s
applicable pro rata share of any Borrowing, the Administrative Agent may assume that such Lender has made its applicable pro rata share of such Borrowing available to the Administrative Agent on the date of such Borrowing in accordance with
Section 2.4(a), and the Administrative Agent may, in reliance upon such assumption, make available to the Borrower on such date a corresponding amount. If and to the extent that such Lender shall not have so made its applicable pro rata share
of such Borrowing available to the Administrative Agent, such Lender and the Borrower severally agree to immediately repay to the Administrative Agent on demand such corresponding amount, together with interest on such amount, for each day from the
date such amount is made available to the Borrower until the date such amount is repaid to the Administrative Agent, at (i) in the case of the Borrower, the interest rate applicable on such day to Advances comprising such Borrowing and
(ii) in the case of such Lender, the lesser of (A) the Federal Funds Rate for such day and (B) the Maximum Rate. If such Lender shall repay to the Administrative Agent such corresponding amount and interest as provided above, such
corresponding amount so repaid shall constitute such Lender’s Advance as part of such Borrowing for purposes of this Agreement even though not made on the same day as the other Advances comprising such Borrowing. 

  
 -31-

(a) Right to Prepay. The Borrower shall have no right to prepay any principal amount of any Advance except as provided in this

to the Administrative Agent stating the proposed date and aggregate principal amount of such prepayment. If any such notice is given, the Borrower shall prepay Advances comprising part of the same Borrowing in whole or ratably in part in an
aggregate principal amount equal to the amount specified in such notice, together with accrued interest to the date of such prepayment on the principal amount prepaid and amounts, if any, required to be paid pursuant to Section 2.10 as a
result of such prepayment being made on such date; provided that (A) each optional prepayment of LIBOR Advances shall be in a minimum amount not less than $200,000 and in multiple integrals of $100,000 in excess thereof, (B) each
optional prepayment of Base Rate Advances shall be in a minimum amount not less than $100,000 and in multiple integrals of $100,000 in excess thereof and (C) each optional prepayment of Swing Line Advances shall have no minimum requirement. If
an AutoBorrow Agreement is in effect, each prepayment of Swing Line Advances shall be made as provided in such AutoBorrow Agreement.

outstanding principal amount of the Revolving Advances on the Maturity Date. 
 (b) Swing Line Advances. Each Swing Line Advance

 Section 2.7 Fees. 

(a) Commitment Fees. The Borrower agrees to pay to the Administrative Agent for the account of each Lender a Commitment Fee on the
average daily amount by which (i) such Lender’s Revolving Commitment exceeds (ii) the sum of such Lender’s outstanding Revolving Advances plus such Lender’s Revolving Pro Rata Share of the Letter of Credit Exposure, at the
rate equal to the Applicable Margin for Commitment Fees for such period; provided that, no Commitment Fee shall accrue on the Revolving Commitment of a Defaulting Lender during the period such Lender remains a Defaulting Lender. The
Commitment Fee is due quarterly in arrears on March 31, June 30, September 30, and December 31 of each year commencing on March 31, 2010, and on the Maturity Date. For purposes of this Section 2.7(a) only,

 -32- 

 (b) Fees for Letters of Credit. The Borrower agrees to pay the following: 

(i) To the Administrative Agent for the pro rata benefit of the Lenders a per annum letter of credit fee for each Letter of
Credit issued hereunder, for the period such Letter of Credit is to be outstanding, in an amount equal to the greater of (A) the Applicable Margin for LIBOR Advances per annum on the face amount of such Letter of Credit, and (B) $600 per
Letter of Credit. Such fee shall be due and payable quarterly in arrears on March 31, June 30, September 30, and December 31 of each year, and on the Maturity Date. 

(ii) To the Issuing Lender, a fronting fee for each Letter of Credit equal to the greater of (A) 0.250% per annum on
the face amount of such Letter of Credit and (B) $600. Such fee shall be due and payable in advance on the date of the issuance of the Letter of Credit, and, in the case of an increase or extension only, on the date of such increase or such
extension. 
 (iii) To the Administrative Agent for the pro rata benefit of the Lenders such additional per annum letter of
credit fee for each commercial Letter of Credit issued hereunder, for the period such Letter of Credit is to be outstanding, in an amount agreed to between the Borrower and the Issuing Lender in writing. Such fee shall be due and payable quarterly
in arrears on March 31, June 30, September 30, and December 31 of each year, and on the Maturity Date. 

(iv) To the Issuing Lender, an additional fronting fee for each commercial Letter of Credit equal an amount agreed to between

(v) To the Issuing Lender such other usual and customary fees associated with any transfers, amendments, drawings, negotiations
or reissuances of any Letters of Credit. Such fees shall be due and payable as requested by the Issuing Lender in accordance with the Issuing Lender’s then current fee policy.

set forth in the Fee Letter. 
 Section 2.8 Interest. 

(a) Base Rate Advances. Each Base Rate Advance shall bear interest at the Adjusted Base Rate in effect from time to time plus
the Applicable Margin for Base Rate Advances for such period, provided that while an Event of Default is continuing the Base Rate Advances shall bear interest at the Adjusted Base Rate in effect from time to time plus the Applicable
Margin plus 2%. The Borrower shall pay to Administrative Agent for the ratable account of each Lender all accrued but unpaid interest on such Lender’s Base Rate Advances on each March 31, June 30, September 30,
and December 31 commencing on March 31, 2010, and on the Maturity Date. The Swing Line Advances shall bear interest only at the Adjusted Base Rate plus the Applicable Margin for Base Rate Advances or such other per annum rate to be agreed
to between the Borrower and the Swing Line Lender; provided that while an Event of Default is continuing the Swing Line Advances shall bear interest at the Adjusted Base Rate in effect from time to time plus the Applicable Margin for
Base Rate Advances plus 2%. 
 (b) LIBOR Advances. Each LIBOR Advance shall bear interest during its Interest Period equal to
at all times the LIBO Rate for such Interest Period plus the Applicable Margin for LIBOR 

  
 -33- 

 
Advances for such period; provided that while an Event of Default is continuing, each LIBOR Advance shall bear interest at the LIBO Rate in effect from time to time plus the
Applicable Margin plus 2%. The Borrower shall pay to the Administrative Agent for the ratable account of each Lender all accrued but unpaid interest on each of such Lender’s LIBOR Advances on the last day of the Interest Period therefor
(provided that for LIBOR Advances with six month Interest Periods, accrued but unpaid interest shall also be due on the day three months from the first day of such Interest Period), on the date any LIBOR Advance is repaid, and on the Maturity Date.

 (c) Retroactive Adjustments of Applicable Margin. In the event that any financial statement or Compliance Certificate delivered
pursuant to Section 5.2 is shown to be inaccurate (regardless of whether this Agreement or the Revolving Commitments are in effect when such inaccuracy is discovered), and such inaccuracy, if corrected, would have led to the application of a
higher Applicable Margin for any period (an “Applicable Period”) than the Applicable Margin applied for such Applicable Period, then (i) the Borrower shall immediately deliver to the Administrative Agent a corrected Compliance
Certificate for such Applicable Period, (ii) the Applicable Margin shall be determined as if the higher Applicable Margin that would have applied were applicable for such Applicable Period (and in any event at Level III if the inaccuracy was
the result of dishonesty, fraud or willful misconduct), and (iii) the Borrower shall immediately, without further action by the Administrative Agent, any Lender or the Issuing Lender, pay to the Administrative Agent for the account of the
applicable Lenders, the accrued additional interest owing as a result of such increased Applicable Margin for such Applicable Period. This Section 2.8(c) shall not limit the rights of the Administrative Agent and Lenders with respect to the
default rate of interest as set forth in Section 2.8(a) and Section 2.8(b) and Article 7. The Borrower’s obligations under this Section 2.8(c) shall survive the termination of the Revolving Commitments and the repayment of all
other Obligations hereunder. 
 Section 2.9 Illegality. If any Lender shall notify the Borrower that the introduction of or any
change in or in the interpretation of any law or regulation makes it unlawful, or that any central bank or other governmental authority asserts that it is unlawful, for such Lender or its applicable Lending Office to perform its obligations under
this Agreement to make, maintain, or fund any LIBOR Advances of such Lender then outstanding hereunder, (a) the Borrower shall, no later than 11:00 a.m. (Houston, Texas, time) (i) if not prohibited by law, on the last day of the Interest
Period for each outstanding LIBOR Advance or (ii) if required by such notice, on the second Business Day following its receipt of such notice, prepay all of the LIBOR Advances of such Lender then outstanding, together with accrued interest on
the principal amount prepaid to the date of such prepayment and amounts, if any, required to be paid pursuant to Section 2.10 as a result of such prepayment being made on such date, (b) such Lender shall simultaneously make a Base Rate
Advance to the Borrower on such date in an amount equal to the aggregate principal amount of the LIBOR Advances prepaid to such Lender, and (c) the right of the Borrower to select LIBOR Advances from such Lender for any subsequent Borrowing
shall be suspended until such Lender shall notify the Borrower that the circumstances causing such suspension no longer exist. Each Lender agrees to use commercially reasonable efforts (consistent with its internal policies and legal and regulatory
restrictions) to designate a different Lending Office if the making of such designation would avoid the effect of this paragraph and would not, in the reasonable judgment of such Lender, be otherwise disadvantageous to such Lender. 

Section 2.10 Breakage Costs. Upon demand of any Lender (with a copy to the Administrative Agent) from time to time, the Borrower
shall promptly compensate such Lender for and hold such Lender harmless from any loss, cost or expense incurred by it as a result of: 
 (a)
any continuation, conversion, payment or prepayment (including any deemed payment or repayment and any reallocated repayment to non-defaulting Lenders provided for in Section 2.12(a)) of any Advance other than a Base Rate Advance on a day other
than the last day of the Interest Period for such Advance (whether voluntary, mandatory, automatic, by reason of acceleration, or otherwise); 

  
 -34- 

 (b) any failure by the Borrower (for a reason other than the failure of such Lender to make an
Advance) to prepay, borrow, continue or convert any Advance other than a Base Rate Advance on the date or in the amount notified by the Borrower; or 

(c) any assignment of an LIBO Rate Advance on a day other than the last day of the Interest Period therefor as a result of a request by the
Borrower pursuant to Section 2.14; 
 including any loss of anticipated profits, any foreign exchange losses and any loss or expense arising from the
liquidation or reemployment of funds obtained by it to maintain such Advance, from fees payable to terminate the deposits from which such funds were obtained or from the performance of any foreign exchange contract. The Borrower shall also pay any
customary administrative fees charged by such Lender in connection with the foregoing. For purposes of calculating amounts payable by the Borrower to the Lenders under this Section 2.10, the requesting Lender shall be deemed to have funded the
LIBO Rate Advances made by it at the LIBO Base Rate used in determining the LIBO Rate for such Advance by a matching deposit or other borrowing in the offshore interbank market for Dollars for a comparable amount and for a comparable period, whether
or not such LIBO Rate Advance was in fact so funded. 
 Section 2.11 Increased Costs. 

(a) LIBOR Advances. If any Change in Law shall: 

(i) impose, modify, or deem applicable any reserve, special deposit, assessment, or similar requirement (other than by way of
imposition or increase of reserve requirements included in the LIBO Rate Reserve Percentage) relating to any extensions of credit or other assets of, or any deposits with or other liabilities or commitments of, financial institutions generally,
including such Lender (or its applicable Lending Office), including the Revolving Commitments of such Lender hereunder; or 

(ii) impose on financial institutions generally, including such Lender (or its applicable Lending Office), or on the London
interbank market any other condition affecting this Agreement or its Notes or any of such extensions of credit or liabilities or commitments; 
 and the
result of any of the foregoing is to increase the cost to such Lender (or its applicable Lending Office) of making, Converting into, continuing, or maintaining any LIBOR Advances or to reduce any sum received or receivable by such Lender (or its
applicable Lending Office) under this Agreement or its Notes with respect to any LIBOR Advances, then the Borrower shall pay to such Lender within three Business Days after written demand made by such Lender such amount or amounts as such Lender
determines in good faith to be necessary to compensate such Lender for such increased cost or reduction. 
 (b) Capital Adequacy. If,
after the Effective Date, any Lender or the Issuing Lender shall have determined that any Change in Law affecting such Lender or Issuing Lender or any lending office of such Lender or such Lender’s or Issuing Lender’s holding company, if
any, regarding capital requirements has or would have the effect of reducing the rate of return on the capital of financial institutions generally, including such Lender or the Issuing Lender or any corporation controlling such Lender or the Issuing
Lender, as a consequence of such Lender’s or the Issuing Lender’s obligations hereunder to a level below that which such Lender or the Issuing Lender or such corporation could have achieved but for such Change in Law (taking into
consideration its policies with respect to capital adequacy), then from time to time within three Business Days after written demand by such Lender or the 

  
 -35- 

 
Issuing Lender, as the case may be, the Borrower shall pay to such Lender or the Issuing Lender such additional amount or amounts as such Lender determines in good faith to be necessary to
compensate such Lender or the Issuing Lender for such reduction. 
 (c) Mitigation. Each Lender shall promptly notify the Borrower
and the Administrative Agent of any event of which it has knowledge, occurring after the Effective Date, which will entitle such Lender to compensation pursuant to this Section 2.11 and will designate a different Lending Office if such
designation will avoid the need for, or reduce the amount of, such compensation and will not, in the reasonable judgment of such Lender, be otherwise disadvantageous to it. Any Lender claiming compensation under this Section 2.11 shall furnish
to the Borrower and the Administrative Agent a statement setting forth the additional amount or amounts to be paid to it hereunder which shall be determined by such Lender in good faith and which shall be conclusive in the absence of manifest error.
In determining such amount, such Lender may use any reasonable averaging and attribution methods. 
 (d) Delay in Requests. Failure
or delay on the part of any Lender or Issuing Lender to demand compensation pursuant to this Section 2.11 shall not constitute a waiver of such Lender’s or such Issuing Lender’s right to demand such compensation, provided that
the Borrower shall not be required to compensate a Lender or Issuing Lender pursuant to this Section 2.11 for any increased costs incurred or reductions suffered more than one year prior to the date that such Lender or Issuing Lender, as the
case may be, notifies the Borrower and the Administrative Agent of the Change in Law giving rise to such increased costs or reductions and of such Lender’s or Issuing Lender’s intention to claim compensation therefor (except that, if the
Change in Law giving rise to such increased costs or reductions is retroactive, then the one-year period referred to above shall be extended to include the period of retroactive effect thereof). 

Section 2.12 Payments and Computations. 

(a) Payments. All payments of principal, interest, and other amounts to be made by the Borrower under this Agreement and other Credit
Documents shall be made to the Administrative Agent in Dollars and in immediately available funds, without setoff, deduction, or counterclaim; provided that, the Borrower may setoff amounts owing to any Lender that is at such time a Defaulting
Lender against Advances that such Defaulting Lender failed to the fund to the Borrower under this Agreement (the “Unfunded Advances”) so long as (i) the Borrower shall have delivered prior written notice of such setoff to the
Administrative Agent and such Defaulting Lender, (ii) the Advances made by the non-defaulting Lenders as part of the original Borrowing to which the Unfunded Advances applied shall still be outstanding, (iii) if such Defaulting Lender
failed to fund Advances under more than one Borrowing, such setoff shall be applied in a manner satisfactory to the Administrative Agent, and (iv) upon the application of such setoff, the Unfunded Advances shall be deemed to have been made by
such Defaulting Lender on the effective date of such setoff. 
 (b) Payment Procedures. The Borrower shall make each payment under
this Agreement and under the Notes not later than 11:00 a.m. (Houston, Texas time) on the day when due in Dollars to the Administrative Agent at the location referred to in the Notes (or such other location as the Administrative Agent shall
designate in writing to the Borrower) in same day funds. The Administrative Agent will promptly thereafter, and in any event prior to the close of business on the day any timely payment is made, cause to be distributed like funds relating to the
payment of principal, interest or fees ratably (other than amounts payable solely to the Administrative Agent or a specific Lender pursuant to Sections 2.9, 2.10, 2.11, 2.13, 2.14, and 9.2 but after taking into account payments effected pursuant to
Section 9.1) in accordance with each Lender’s applicable pro rata share to the Lenders for the account of their respective applicable Lending Offices, and like funds relating to the payment of any other amount payable to any Lender to such
Lender for the account of its applicable Lending Office, in each case to be applied in 

  
 -36- 

 
accordance with the terms of this Agreement. Upon receipt of other amounts due solely to the Administrative Agent, the Issuing Lender, the Swing Line Lender, or a specific Lender, the
Administrative Agent shall distribute such amounts to the appropriate party to be applied in accordance with the terms of this Agreement. 

(c) Non-Business Day Payments. Whenever any payment shall be stated to be due on a day other
than a Business Day, such payment shall be made on the next succeeding Business Day, and such extension of time shall in such case be included in the computation of payment of interest or fees, as the case may be; provided that if such
extension would cause payment of interest on or principal of LIBOR Advances to be made in the next following calendar month, such payment shall be made on the next preceding Business Day. 

(d) Computations. All computations of interest for Base Rate Advances shall be made by the Administrative Agent on the basis of a year
of 365/366 days (other than based on the Daily One-Month LIBOR) and all computations of all other interest and fees shall be made by the Administrative agent on the basis of a year of 360 days, in each case for the actual number of days (including
the first day, but excluding the last day) occurring in the period for which such interest or fees are payable. Each determination by the Administrative Agent of an amount of interest or fees shall be conclusive and binding for all purposes, absent
manifest error. 
 (e) Sharing of Payments, Etc. If any Lender shall obtain any payment (whether voluntary, involuntary, through the
exercise of any right of set-off, or otherwise) on account of the Advances made by it in excess of its ratable share of payments on account of the Advances or Letter of Credit Obligations obtained by the
Lenders (other than as a result of a termination of a Defaulting Lender’s Revolving Commitment under Section 2.1(b)(ii), the setoff right of the Borrower under clause (a) above, or the non-pro rata application of payments provided in
the last sentence of this clause (e)), such Lender shall notify the other Lenders and forthwith purchase from the other Lenders such participations in the Advances made by it or the Letter of Credit Obligations held by it as shall be necessary to
cause such purchasing Lender to share the excess payment ratably with the other Lenders; provided that if all or any portion of such excess payment is thereafter recovered from such purchasing Lender, such purchase from the other Lenders
shall be rescinded and each such Lender shall repay to the purchasing Lender the purchase price to the extent of such Lender’s ratable share, but without interest. The Borrower agrees that any Lender so purchasing a participation from another
Lender pursuant to this Section 2.12(e) may, to the fullest extent permitted by law, exercise all its rights of payment (including the right of set-off) with respect to such participation as fully as if
such Lender were the direct creditor of the Borrower in the amount of such participation. If a Lender fails to fund a Revolving Advance with respect to a Borrowing as and when required hereunder and the Borrower subsequently makes a repayment of any
Revolving Advances, then, after taking into account any setoffs made pursuant to Section 2.12(a) above, such payment shall be applied among the non-defaulting Lenders ratably in accordance with their respective Revolving Commitment percentages
until each Lender (including any Lender that is at such time a Defaulting Lender) has its percentage of all of the outstanding Revolving Advances and the balance of such repayment shall be applied among the Lenders in accordance with their Revolving
Pro Rata Share. 
 Section 2.13 Taxes. 

(a) No Deduction for Certain Taxes. Any and all payments by any Credit Party under any of the Credit Documents to the Administrative
Agent, the Issuing Lender, or a Lender shall be made, in accordance with Section 2.12, free and clear of and without deduction for any and all present or future taxes, levies, imposts, deductions, charges, or withholdings, and all liabilities
with respect thereto, excluding, in the case of the Administrative Agent, the Issuing Lender, or a Lender, (i) taxes imposed on its income and franchise (or margin) taxes imposed on it by the jurisdiction (or any political subdivision

  
 -37- 

 
thereof) under (A) the laws of which (or under the laws of a political subdivision of which) the Administrative Agent, the Issuing Lender, or such Lender is organized or in which its
principal executive office is located, (B) in the case of each Lender, the laws of which (or under the laws of a political subdivision of which) such Lender’s applicable Lending Office is located, and (C) the laws of the State of
Texas; and (ii) any taxes imposed by the United States of America by means of withholding at the source, if and to the extent such United States withholding taxes are in effect on the date a Lender becomes a Lender hereunder (all such
nonexcluded taxes, levies, imposts, deductions, charges, withholdings, and liabilities being hereinafter referred to as “Taxes”). Except as provided in Section 2.13(f), if the Borrower shall be required by law to deduct any
Taxes from or in respect of any sum payable to the Administrative Agent, the Issuing Lender, or any Lender, (i) the sum payable shall be increased as may be necessary so that, after making all required deductions (including deductions
applicable to additional sums payable under this Section 2.13), such Lender 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 or other authority in accordance with applicable law. 

(b) Other Taxes. In addition, except as provided in Section 2.13(f), the Borrower agrees to pay any present or future stamp or
documentary taxes or any other excise or property taxes, charges, or similar levies which arise from any payment made under any Credit Document or from the execution, delivery, or registration of, or otherwise with respect to, this Agreement, the
Notes, or the other Credit Documents (hereinafter referred to as “Other Taxes”). 
 (c) Indemnification. EXCEPT AS PROVIDED
IN SECTION 2.13(F), THE BORROWER INDEMNIFIES EACH LENDER, THE ISSUING LENDER, AND THE ADMINISTRATIVE AGENT FOR THE FULL AMOUNT OF TAXES OR OTHER TAXES (INCLUDING, WITHOUT LIMITATION, ANY TAXES OR OTHER TAXES IMPOSED ON AMOUNTS PAYABLE UNDER THIS
SECTION 2.13) PAID BY SUCH LENDER, THE ISSUING LENDER, OR THE ADMINISTRATIVE AGENT (AS THE CASE MAY BE) AND ANY LIABILITY (INCLUDING INTEREST AND EXPENSES) ARISING THEREFROM OR WITH RESPECT THERETO, WHETHER OR NOT SUCH TAXES OR OTHER TAXES WERE
CORRECTLY OR LEGALLY ASSERTED. 
 (d) Evidence of Tax Payments. As soon as practicable after any payment of Taxes or Other Taxes by
any Credit Party to a Governmental Authority, the Borrower shall deliver to the Administrative Agent the original or a certified copy of any receipt issued by such Governmental Authority evidencing such payment. 

(e) Foreign Lender Withholding Exemption. Each Lender that is not incorporated under the laws of the United States of America or a
state thereof and that is entitled to an exemption from United States withholding tax with respect to payments under this Agreement under applicable law or any treaty to which the United States is a party 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 (including Internal Revenue Service Forms W-8BEN or W-8ECI) prescribed by applicable law or reasonably requested by
the Borrower as will permit such payments to be made without withholding. 
 (f) Failure to Provide Forms. For any period with
respect to which a Lender has failed to provide the Borrower or the Administrative Agent with the appropriate forms referred to in this Section 2.13 (unless such failure is due to a change in treaty, law or regulation occurring after the date
on which such Lender becomes a Lender hereunder), such Lender shall not be entitled to indemnification or payment under Section 2.13(a), (b), or (c) with respect to Taxes imposed by the United States; provided that if a Lender, that
is otherwise exempt from or subject to a reduced rate of withholding tax, becomes 

  
 -38- 

 
subject to Taxes because of its failure to deliver a form required hereunder, the Borrower shall take such steps as such Lender shall reasonably request, and at the expenses of such Lender, to
assist such Lender to recover such Taxes. 
 (g) Mitigation. Each Lender shall use reasonable efforts (consistent with its internal
policies and legal and regulatory restrictions) to select a jurisdiction for its applicable Lending Office or change the jurisdiction of its applicable Lending Office, as the case may be, so as to avoid the imposition of any Taxes or Other Taxes or
to eliminate or reduce the payment of any additional sums under this Section 2.13; provided, that no such selection or change of jurisdiction for its applicable Lending Office shall be made if, in the reasonable judgment of such Lender, such
selection or change would be disadvantageous to such Lender. 
 (h) Tax Credits and Refunds. If the Administrative Agent, any Lender
or the Issuing 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, it shall pay to the Borrower an amount equal to such refund (but only to the extent of indemnity payments made, or additional amounts paid, by the Borrower under this Section with respect to the Taxes or Other Taxes giving rise to such
refund), net of all out-of-pocket expenses of the Administrative Agent, such Lender or the Issuing Lender, as the case may be, 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, such Lender or the Issuing 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, such Lender or the Issuing Lender in the event the Administrative Agent, such Lender or the Issuing Lender is required to repay such refund to such Governmental Authority. This subsection shall
not be construed to require the Administrative Agent, any Lender or the Issuing Lender to make available its tax returns (or any other information relating to its taxes that it deems confidential) to any Borrower or any other Person. 

(i) Payment. If the Administrative Agent or any Lender becomes entitled to receive payment of Taxes, Other Taxes or additional sums
pursuant to this Section 2.13, it shall give notice and demand thereof to the Borrower, and the Borrower (unless the Administrative Agent or Lender shall withdraw such notice and demand or the Borrower is not obligated to pay such amounts)
shall pay such Taxes, Other Taxes or additional sums within 30 days after the Borrower’s receipt of such notice and demand. 

Section 2.14 Replacement of Lenders. If (a) the Borrower is required pursuant to Section 2.11 or 2.13 to make any
additional payment to any Lender, (b) any Lender’s obligation to make or continue, or to convert Base Rate Advances into, LIBOR Advances shall be suspended pursuant to 2.4(c)(iii) or 2.9, or (c) any Lender is a Defaulting Lender or a
Potential Defaulting Lender (any such Lender described in any of the preceding clauses (a) – (c), being a “Subject Lender”), then (i) in the case of a Defaulting Lender or a Potential Defaulting Lender, the
Administrative Agent may, upon notice to the Subject Lender and the Borrower, require such Subject Lender to assign and delegate, without recourse (in accordance with and subject to the restrictions contained in, and consents required by,
Section 9.7), all of its interests, rights and obligations under this Agreement and the related Credit Documents as a Lender to an Eligible Assignee that shall assume such obligations (which assignee may be another Lender, if a Lender accepts
such assignment) and (ii) in the case of any Subject Lender, including a Potential Defaulting Lender, the Borrower may, upon notice to the Subject Lender and the Administrative Agent and at the Borrower’s sole cost and expense, require
such Subject Lender to assign and delegate, without recourse (in accordance with and subject to the restrictions contained in, and consents required by, Section 9.7), all of its interests, rights and obligations under this Agreement and the
related Credit Documents to an Eligible Assignee that shall assume such obligations (which assignee may be another Lender, if a Lender accepts such assignment), provided that, in any event 

  
 -39- 

 (A) as to assignments requested by the Borrower, the Borrower shall have paid to the
Administrative Agent the assignment fee specified in Section 9.7; 
 (B) such Subject Lender shall have received payment of an amount
equal to the outstanding principal of its applicable Advances and participations in outstanding Letter of Credit Obligations, accrued interest thereon, accrued fees and all other amounts payable to it hereunder and under the other Credit Documents
(including any amounts under Section 2.10) 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); 

(C) in the case of any such assignment resulting from a claim for compensation under Section 2.13, such assignment will result in a
reduction in such compensation or payments thereafter; and 
 (D) such assignment does not conflict with applicable Legal Requirements. 

A Lender shall not be required to make any such assignment or 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. Solely for purposes of effecting any assignment involving a Defaulting Lender under this Section 2.14 and to the extent permitted under applicable
Legal Requirements, each Lender hereby designates and appoints the Administrative Agent as true and lawful agent and attorney-in-fact, with full power and authority, for and on behalf of and in the name of such Lender to execute, acknowledge and
deliver the Assignment and Acceptance required hereunder if such Lender is a Defaulting Lender and such Lender shall be bound thereby as fully and effectively as if such Lender had personally executed, acknowledged and delivered the same. In
lieu of the Borrower or the Administrative Agent replacing a Defaulting Lender as provided in this Section 2.14, the Borrower may terminate such Defaulting Lender’s Revolving Commitment as provided in Section 2.1(b)(ii). 

Section 2.15 Defaulting Lender Cure. If the Borrower, the Administrative Agent, and the Issuing Lender agree in writing in their
discretion that a Lender that is a Defaulting Lender or a Potential Defaulting Lender should no longer be deemed to be a Defaulting Lender or Potential Defaulting Lender, as the case may be, the Administrative Agent will so notify the parties
hereto, whereupon as of the effective date specified in such notice and subject to any conditions set forth therein, such Lender will, to the extent applicable, purchase such portion of outstanding Advances of the other Lenders and/or make such
other adjustments as the Administrative Agent may determine to be necessary to cause the Advances and Letter of Credit Exposure of the Lenders to be on a pro rata basis in accordance with their respective Revolving Commitments,
whereupon such Lender will cease to be a Defaulting Lender or Potential Defaulting Lender (and the Advances and Letter of Credit Exposure of each Lender will automatically be adjusted on a prospective basis to reflect the foregoing); provided
that no adjustments will be made retroactively with respect to fees accrued or payments made by or on behalf of the Borrower while such Lender was a Defaulting Lender; and provided, further, that except to the extent otherwise expressly
agreed by the affected parties, no cessation hereunder as being a Defaulting Lender or Potential Defaulting Lender will constitute a waiver or release of any claim of any party hereunder arising from such Lender’s having been a Defaulting
Lender or Potential Defaulting Lender.

jurisdiction of incorporation or formation and is authorized to do business and is in good standing in all jurisdictions in which such qualifications or authorizations are necessary except where the failure to be so qualified or authorized could not
reasonably be expected to result in a Material Adverse Change. As of the Effective Date, each Credit Party’s type of organization and jurisdiction of incorporation or formation are set forth on Schedule 4.1. 

Section 4.2 Authorization. The execution, delivery, and performance by each Credit Party of each Credit Document to which such
Credit Party is a party and the consummation of the transactions contemplated thereby (a) are within such Credit Party’s powers, (b) have been duly authorized by all necessary corporate, limited liability company or partnership

general principles of equity whether applied by a court of law or equity. 
 Section 4.4 Financial Condition. 

(a) The Borrower has delivered to the Administrative Agent the unaudited financial statements for the Borrower and its Subsidiaries dated as
of September 30, 2009 for the fiscal quarter ending thereon. The financial statements referred to in the preceding sentence have been prepared in accordance with GAAP and present fairly the consolidated financial condition of the aforementioned
Persons as of the respective dates thereof. As of the date of the aforementioned financial statements, there were no material contingent obligations, liabilities for taxes, unusual forward or long-term

conditions (including current and reasonably foreseeable business conditions) believed to be reasonable at the time such projections, estimates, and pro forma financial information were furnished. 

  
 -44- 

 Section 4.7 Litigation. Except as set forth in Schedule 4.7, there are no actions,
suits, or proceedings pending or, to any Credit Party’s knowledge, threatened against the Borrower or any Subsidiary, at law, in equity, or in admiralty, or by or before any Governmental Authority, which could reasonably be expected to result
in a Material Adverse Change. Additionally, except as disclosed in writing to the Administrative Agent and the Lenders, there is no pending or, to the knowledge of any Credit Party, threatened action or proceeding instituted against the Borrower or
any Subsidiary which seeks to adjudicate the Borrower or any Subsidiary as bankrupt or insolvent, or seeking liquidation, winding up, reorganization, arrangement, adjustment, protection, relief, or composition of it or its debts under any law
relating to bankruptcy, insolvency or reorganization or relief of debtors, or seeking the entry of an order for relief or the appointment of a receiver, trustee or other similar official for it or for any substantial part of its Property. 

Section 4.8 Compliance with Agreements. 

(a) Neither the Borrower nor any of its Subsidiaries is a party to any indenture, loan or credit agreement or any lease or any other types of
agreement or instrument or subject to any charter or corporate restriction or provision of applicable law or governmental regulation the performance of or compliance with which could reasonably be expected to cause a Material Adverse Change. Neither
the Borrower nor any of its Subsidiaries is in default under or with respect to any contract, agreement, lease or any other types of agreement or instrument to which the Borrower or such Subsidiary is a party and which could reasonably be expected
to cause a Material Adverse Change. To the best knowledge of the Credit Parties, neither the Borrower nor any of its Subsidiaries is in default under, or has received a notice of default under, any contract, agreement, lease or any other document or
instrument to which the Borrower or its Subsidiaries is a party which is continuing and which, if not cured, could reasonably be expected to cause a Material Adverse Change. 

(b) No Default has occurred and is continuing. 

Section 4.9 Pension Plans. (a) Except for matters that could not reasonably be expected to result in a Material Adverse
Change, all Plans are in compliance with all applicable provisions of ERISA, (b) no Termination Event has occurred with respect to any Plan that would result in an Event of Default under Section 7.1(i), and, except for matters that could
not reasonably be expected to result in a Material Adverse Change, each Plan has complied with and been administered in accordance with applicable provisions of ERISA and the Code, (c) no “accumulated funding deficiency” (as defined
in Section 302 of ERISA) has occurred, and for plan years after December 31, 2007, no unpaid minimum required contribution exists, and there has been no excise tax imposed under Section 4971 of the Code, (d) to the knowledge of
Credit Parties, no Reportable Event has occurred with respect to any Multiemployer Plan, and each Multiemployer Plan has complied with and been administered in accordance with applicable provisions of ERISA and the Code in all material respects,
(e) the present value of all benefits vested under each Plan (based on the assumptions used to fund such Plan) did not, as of the last annual valuation date applicable thereto, exceed the value of the assets of such Plan allocable to such
vested benefits in an amount that could reasonably be expected to result in a Material Adverse Change, (f) neither the Borrower nor any member of the Controlled Group has had a complete or partial withdrawal from any Multiemployer Plan for
which there is any unsatisfied withdrawal liability that could reasonably be expected to result in a Material Adverse Change or an Event of Default under Section 7.1(i), and (g) except for matters that could not reasonably result in a
Material Adverse Change, as of the most recent valuation date applicable thereto, neither the Borrower nor any member of the Controlled Group would become subject to any liability under ERISA if the Borrower or any Subsidiary has received notice
that any Multiemployer Plan is insolvent or in reorganization. Based upon GAAP existing as of the date of this Agreement and current factual circumstances, no Credit Party has any reason to believe that the annual cost during the term of this
Agreement to the Borrower or any Subsidiary for post-retirement 

  
 -45- 

 
benefits to be provided to the current and former employees of the Borrower or any Subsidiary under Plans that are welfare benefit plans (as defined in Section 3(1) of ERISA) could, in the
aggregate, reasonably be expected to cause a Material Adverse Change.

Permits necessary for the ownership and operation of its Properties and the conduct of its businesses; (ii) is in material compliance with all terms and conditions of such Permits and with all other material requirements of applicable
Environmental Laws; (iii) has not received written notice of any material violation or alleged material violation of any Environmental Law or Environmental Permit that has not been resolved; and (iv) is not subject to any actual or
contingent Environmental Claim which could reasonably be expected to cause a Material Adverse Change. 
 (b) Certain Liabilities. To
the Credit Parties’ best knowledge, none of the present or previously owned or operated Property of any Credit Party or of any Subsidiary thereof, wherever located, (i) has been placed on or proposed to be placed on the National Priorities
List, the Comprehensive Environmental Response Compensation Liability Information System list, or their state or local analogs, or have been otherwise investigated, designated, listed, or identified as a potential site for removal, remediation,
cleanup, closure, restoration, reclamation, or other response activity under any Environmental Laws; (ii) is subject to a Lien, arising under or in connection with any Environmental Laws, that attaches to any revenues or to any Property owned
or operated by any Credit Party, wherever located, which could reasonably be expected to cause a Material Adverse Change; or (iii) has been the site of any Release of Hazardous Substances or Hazardous Wastes from present or past operations
which has caused at the site or at any third-party site any condition that has resulted in or could reasonably be expected to result in the need for Response that could cause a Material Adverse Change. 

(c) Certain Actions. Without limiting the foregoing, (i) all necessary material notices have been properly filed, and no further
action is required under current applicable Environmental Law as to each Response undertaken by the Borrower, any of its Subsidiaries or any of the Borrower’s or such Subsidiary’s former Subsidiaries on any of their presently or formerly
owned or operated Property and (ii) to the Credit Parties’ knowledge, the present and future liability, if any, of the Borrower or of any Subsidiary which could reasonably be expected to arise in connection with requirements under
Environmental Laws will not result in a Material Adverse Change. 
 Section 4.11 Subsidiaries. As of the Effective Date, the
Borrower has no Subsidiaries other than those listed on Schedule 4.11. Each Material Domestic Subsidiary of the Borrower (including any such Material Domestic Subsidiary formed or acquired subsequent to the Effective Date) has complied with the
requirements of Section 5.6. 
 Section 4.12 Investment Company Act. Neither the Borrower nor any Subsidiary is an
“investment company” or a company “controlled” by an “investment company” within the meaning of the Investment Company Act of 1940, as amended. Neither the Borrower nor any Subsidiary is subject to regulation under any
Federal or state statute, regulation or other Legal Requirement which limits its ability to incur Debt. 
 Section 4.13 Taxes.
To the extent that failure to do so could reasonably, either individually or in the aggregate, be expected to result in a Material Adverse Change, proper and accurate (in all material respects), federal, state, local and foreign tax returns, reports
and statements required to be filed (after giving effect to any extension granted in the time for filing) by the Borrower and each Subsidiary or any member of the Affiliated Group as determined under Section 1504 of the Code (hereafter
collectively 

  
 -46- 

 
called the “Tax Group”) have been filed with the appropriate Governmental Authorities, and all taxes (which are material in amount) and other impositions due and payable have
been timely paid prior to the date on which any fine, penalty, interest, late charge or loss may be added thereto for non-payment thereof except where contested in good faith and by appropriate proceeding. Neither the Borrower nor any member of the
Tax Group has given, or been requested to give, a waiver of the statute of limitations relating to the payment of any federal, state, local or foreign taxes or other impositions. None of the Property owned by the Borrower or any other member of the
Tax Group is Property which the Borrower or any member of the Tax Group is required to treat as being owned by any other Person pursuant to the provisions of Section 168(f)(8) of the Code. Proper and accurate amounts have been withheld by the
Borrower and all other members of the Tax Group from their employees for all periods to comply in all material respects with the tax, social security and unemployment withholding provisions of applicable federal, state, local and foreign law. 

Section 4.14 Permits, Licenses, etc. Each of the Borrower and its Subsidiaries possesses all permits, licenses, patents, patent
rights or licenses, trademarks, trademark rights, trade names rights, and copyrights which are material to the conduct of its business. Each of the Borrower and its Subsidiaries manages and operates its business in accordance with all applicable
Legal Requirements except where the failure to so manage or operate could not reasonably be expected to result in a Material Adverse Change; provided that this Section 4.14 does not apply with respect to Environmental Permits or Legal
Requirements of Environmental Law. 
 Section 4.15 Use of Proceeds. The proceeds of the Advances will be used by the Borrower
for the purposes described in Section 6.6. No Credit Party is engaged in the business of extending credit for the purpose of purchasing or carrying margin stock (within the meaning of Regulation U). No proceeds of any Advance will be used
to purchase or carry any margin stock in violation of Regulation T, U or X. 
 Section 4.16 Condition of Property;
Casualties. The material Properties used or to be used in the continuing operations of the Borrower and each Subsidiary, are in good working order and condition, normal wear and tear excepted. Neither the business nor the material Properties of

otherwise required by Legal Requirements. 
 Notwithstanding the foregoing, (a) payments and collections received by the Administrative Agent from any
Credit Party that is not a Qualified ECP Guarantor (and any proceeds received in respect of such Credit Party’s Collateral (as defined in the Security Agreement)) shall not be applied to Excluded Swap Obligations with respect to any Credit
Party, provided, however, that the Administrative Agent shall make such adjustments as it determines are appropriate with respect to payments and collections received from the other Credit Parties (or proceeds received in respect of such other
Credit Parties’ Collateral) to preserve, as nearly as possible, the allocation to Secured Obligations otherwise set forth above in this Section 7.6 (assuming that, solely for purposes of such adjustments, Secured Obligations includes
Excluded Swap Obligations), and (b) Banking Services Obligations, Secured Swap Obligations, and Bilateral Obligations may be excluded from the application described above if the Administrative Agent has not received written notice thereof,

sentence shall, by such notice, be deemed to have acknowledged and accepted the appointment of the Administrative Agent pursuant to the terms of Article 8 for itself and its Affiliates as if a “Lender” party hereto.

Section 8.1 Appointment, Powers, and Immunities. Each Lender hereby irrevocably appoints and authorizes the Administrative Agent
to act as its agent under this Agreement and the other Credit Documents with such powers and discretion as are specifically delegated to the Administrative Agent by the terms of this Agreement and the other Credit Documents, together with such other
powers as are reasonably incidental thereto. The Administrative Agent (which term as used in this sentence and in 

  
 -65- 

 
Section 8.5 and the first sentence of Section 8.6 shall include its Affiliates and its own and its Affiliates’ officers, directors, employees, and agents): (a) shall not have
any duties or responsibilities except those expressly set forth in this Agreement and shall not be a trustee or fiduciary for any Lender; (b) shall not be responsible to the Lenders for any recital, statement, representation, or warranty
(whether written or oral) made in or in connection with any Credit Document or any certificate or other document referred to or provided for in, or received by any of them under, any Credit Document, or for the value, validity, effectiveness,
genuineness, enforceability, or sufficiency of any Credit Document, or any other document referred to or provided for therein or for any failure by any Credit Party or any other Person to perform any of its obligations thereunder; (c) shall not
be responsible for or have any duty to ascertain, inquire into, or verify the performance or observance of any covenants or agreements by any Credit Party or the satisfaction of any condition or to inspect the Property (including the books and
records) of any Credit Party or any of its Subsidiaries or Affiliates; (d) shall not be required to initiate or conduct any litigation or collection proceedings under any Credit Document unless requested by the Majority Lenders in writing and
it receives indemnification satisfactory to it from the Lenders; and (e) shall not be responsible for any action taken or omitted to be taken by it under or in connection with any Credit Document, except for its own gross negligence or willful
misconduct. The Administrative Agent may employ agents and attorneys-in-fact and shall not be responsible for the negligence or misconduct of any such agents or attorneys-in-fact selected by the Administrative Agent with reasonable care. 

Section 8.2 Reliance by Administrative Agent. The Administrative Agent shall be entitled to rely upon any certification, notice,
instrument, writing, or other communication (including, without limitation, any thereof by telephone or telecopy) believed by it to be genuine and correct and to have been signed, sent or made by or on behalf of the proper Person or Persons, and
upon advice and statements of legal counsel (including counsel for any Credit Party), independent accountants, and other experts selected by the Administrative Agent. The Administrative Agent may deem and treat the payee of any Notes as the holder
thereof for all purposes hereof unless and until the Administrative Agent receives and accepts an Assignment and Acceptance executed in accordance with Section 9.7. As to any matters not expressly provided for by this Agreement, the
Administrative Agent shall not be required to exercise any discretion or take any action, but shall be required to act or to refrain from acting (and shall be fully protected in so acting or refraining from acting) upon the instructions of the
Majority Lenders, and such instructions shall be binding on all of the Lenders; provided, however, that the Administrative Agent shall not be required to take any action that exposes the Administrative Agent to personal liability or that is
contrary to any Credit Document or applicable law or unless it shall first be indemnified to its satisfaction by the Lenders against any and all liability and expense which may be incurred by it by reason of taking any such action. 

Section 8.3 Defaults. The Administrative Agent shall not be deemed to have knowledge or notice of the occurrence of a Default or
Event of Default unless the Administrative Agent has received written notice from a Lender or the Borrower specifying such Default or Event of Default and stating that such notice is a “Notice of Default”. In the event that the
Administrative Agent receives such a notice of the occurrence of a Default or Event of Default, the Administrative Agent shall give prompt notice thereof to the Lenders. The Administrative Agent shall (subject to Section 8.2) take such action
with respect to such Default or Event of Default as shall reasonably be directed by the Majority Lenders, provided that, unless and until the Administrative Agent shall have received such directions, the Administrative Agent may (but
shall not be obligated to) take such action, or refrain from taking such action, with respect to such Default or Event of Default as it shall deem advisable in the best interest of the Lenders. 

Section 8.4 Rights as Lender. With respect to its Revolving Commitments and the Advances made by it, Wells Fargo (and any
successor acting as Administrative Agent) in its capacity as a Lender hereunder shall have the same rights and powers hereunder as any other Lender and may exercise the 

  
 -66- 

 
same as though it were not acting as the Administrative Agent, and the term “Lender” or “Lenders” shall, unless the context otherwise indicates, include the Administrative
Agent in its individual capacity. Wells Fargo (and any successor acting as Administrative Agent) and its Affiliates may (without having to account therefor to any Lender) accept deposits from, lend money to, make investments in, provide services to,
and generally engage in any kind of lending, trust, or other business with any Credit Party or any of its Subsidiaries or Affiliates as if it were not acting as Administrative Agent, and Wells Fargo (and any successor acting as Administrative Agent)
and its Affiliates may accept fees and other consideration from any Credit Party or any of its Subsidiaries or Affiliates for services in connection with this Agreement or otherwise without having to account for the same to the Lenders.

PORTION OF SUCH LIABILITIES, OBLIGATIONS, LOSSES, DAMAGES, PENALTIES, ACTIONS, JUDGMENTS, SUITS, COSTS, EXPENSES, OR DISBURSEMENTS RESULTING FROM THE ISSUING LENDER’S GROSS NEGLIGENCE OR WILLFUL MISCONDUCT. WITHOUT LIMITATION OF THE FOREGOING,
EACH LENDER AGREES TO REIMBURSE THE ISSUING LENDER PROMPTLY UPON DEMAND FOR ITS RATABLE SHARE (DETERMINED AS SET FORTH ABOVE IN THIS PARAGRAPH) OF ANY OUT-OF-POCKET

Section 8.6 Non-Reliance on Administrative Agent and Other Lenders. Each Lender agrees that it has, independently and without
reliance on the Administrative Agent or any other Lender, and based on such documents and information as it has deemed appropriate, made its own credit analysis of the Borrower and the other Credit Parties and decision to enter into this Agreement
and 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 deem appropriate at the time, continue to make its own analysis and decisions in taking
or not taking action under the Credit Documents. Except for notices, reports, and other documents and information expressly required to be furnished to the Lenders by the Administrative Agent hereunder and for other information in the Administrative
Agent’s possession which has been requested by a Lender and for which such Lender pays the Administrative Agent’s expenses in connection therewith, the Administrative Agent shall not have any duty or responsibility to provide any Lender
with any credit or other information concerning the affairs, financial condition, or business of any Credit Party or any of its Subsidiaries or Affiliates that may come into the possession of the Administrative Agent or any of its Affiliates. 

Section 8.7 Resignation of Administrative Agent and Issuing Lender. The Administrative Agent or the Issuing Lender may resign at
any time by giving written notice thereof to the Lenders and the Borrower. Upon receipt of notice of any such resignation, the Majority Lenders shall have the right to appoint a successor Administrative Agent or Issuing Lender with, so long as no
Event of Default has occurred and is continuing, the consent of the Borrower, which consent shall not be unreasonably withheld. If no successor Administrative Agent or Issuing Lender shall have been so appointed by the Majority Lenders with the
consent of the Borrower, and shall have accepted such appointment, within 30 days after the retiring Administrative Agent’s or Issuing Lender’s giving of notice of resignation, then the retiring Administrative Agent or Issuing Lender may,
on behalf of the Lenders and the Borrower, appoint a successor Administrative Agent or Issuing Lender, which shall be, in the case of a successor agent, a commercial bank organized under the laws of the United States of America or of any State
thereof and having a combined capital and surplus of at least $250,000,000 and, in the case of the Issuing Lender, a Lender; provided that, if the Administrative Agent or Issuing Lender shall notify the Borrower and the

  
 -68- 

 
Lenders that no qualifying Person has accepted such appointment, then such resignation shall nonetheless become effective in accordance with such notice and (1) the retiring Administrative
Agent or Issuing Lender shall be discharged from its duties and obligations hereunder and under the other Credit Documents (except that (A) in the case of any collateral security held by the Administrative Agent on behalf of the Lenders or the
Issuing Lender under any of the Credit Documents, the retiring Administrative Agent shall continue to hold such collateral security until such time as a successor Administrative Agent is appointed and (B) the retiring Issuing Lender shall
remain the Issuing Lender with respect to any Letters of Credit outstanding on the effective date of its resignation or removal and the provisions affecting the Issuing Lender with respect to such Letters of Credit shall inure to the benefit of the
retiring Issuing Lender until the termination of all such Letters of Credit) and (2) all payments, communications and determinations provided to be made by, to or through the retiring Administrative Agent shall instead be made by or to each
Lender and the Issuing Lender directly, until such time as the Required Lenders appoint a successor Administrative Agent or Issuing Lender, as applicable, as provided for above in this paragraph. Upon the acceptance of any appointment as
Administrative Agent or Issuing Lender by a successor Administrative Agent or Issuing Lender, such successor Administrative Agent or Issuing Lender shall thereupon succeed to and become vested with all the rights, powers, privileges, and duties of
the retiring Administrative Agent or Issuing Lender, and the retiring Administrative Agent or Issuing Lender shall be discharged from its duties and obligations under this Agreement and the other Credit Documents, except that the retiring Issuing
Lender shall remain the Issuing Lender with respect to any Letters of Credit outstanding on the effective date of its resignation or removal and the provisions affecting the Issuing Lender with respect to such Letters of Credit shall inure to the
benefit of the retiring Issuing Lender until the termination of all such Letters of Credit. After any retiring Administrative Agent’s or Issuing Lender’s resignation as Administrative Agent or Issuing Lender, the provisions of this
Article 8 shall inure to its benefit as to any actions taken or omitted to be taken by it while it was Administrative Agent or Issuing Lender under this Agreement and the other Credit Documents. 

Section 8.8 Collateral and Guaranty Matters.

such Secured Parties, from time to time, to take any actions with respect to any Collateral or Security Documents which may be necessary to perfect and maintain the Liens upon the Collateral granted pursuant to the Security Documents. The
Administrative Agent is further authorized (but not obligated) on behalf of the Secured Parties, without the necessity of any notice to or further consent from the Secured Parties, from time to time, to take any action in exigent circumstances as
may be reasonably necessary to preserve any rights or privileges of the Secured Parties under the Credit Documents or applicable Legal Requirements. By accepting the benefit of the Liens granted pursuant to the Security Documents, each Secured Party
hereby agrees to the terms of this paragraph (a). 
 (b) The Lenders hereby, and any other Secured Party by accepting the benefit of the
Liens granted pursuant to the Security Documents, irrevocably authorize the Administrative Agent to (i) release any Lien granted to or held by the Administrative Agent upon any Collateral (a) as provided in Section 5.9(b),

made), termination of all Letters of Credit (other than Letters of Credit as to which arrangements satisfactory to the Issuing Lender in its sole discretion have been made), and the payment in full of all outstanding Advances, Letter of Credit
Obligations and all other Secured Obligations payable under this Agreement and under any other Credit Document; (c) constituting property sold or to be sold or Disposed of as part of or in connection with any Disposition permitted under this
Agreement or any other Credit Document; (d) constituting property in which no Credit Party owned an interest at the time the Lien was granted or at any time thereafter (other than as result of a

  
 -69- 

 
transaction that is not permitted under this Agreement); or (e) constituting property leased to any Credit Party under a lease which has expired or has been terminated in a transaction
permitted under this Agreement or is about to expire and which has not been, and is not intended by such Credit Party to be, renewed or extended; and (ii) release a Guarantor from its obligations under a Guaranty and any other applicable Credit
Document if such Person ceases to be a Subsidiary as a result of a transaction permitted under this Agreement. Upon the request of the Administrative Agent at any time, the Secured Parties will confirm in writing the Administrative Agent’s
authority to release particular types or items of Collateral pursuant to this Section 8.8. 
 (c) Notwithstanding anything contained in
any of the Credit Documents to the contrary, the Credit Parties, the Administrative Agent, and each Secured Party hereby agree that no Secured Party shall have any right individually to realize upon any of the Collateral or to enforce the
Guaranties, it being understood and agreed that all powers, rights and remedies hereunder, under the Guaranties and under the Security Documents may be exercised solely by Administrative Agent on behalf of the Secured Parties in accordance with the
terms hereof and the other Credit Documents. By accepting the benefit of the Liens granted pursuant to the Security Documents, each Secured Party not party hereto hereby agrees to the terms of this paragraph (c).

subject to such assignment and payment of the processing fee, the Administrative Agent shall, if such Assignment and Acceptance has been completed, (i) accept such Assignment and Acceptance, (ii) record the information contained therein in
the Register, and (iii) give prompt notice thereof to the parties thereto.

obligations hereunder. 
 (f) Any Lender may furnish any information concerning the Borrower or any of its Subsidiaries in the possession of
such Lender from time to time to assignees and participants (including prospective assignees and participants), subject, however, to the provisions of the following paragraph Section 9.8. 

Section 9.8 Confidentiality. The Administrative Agent, the Swing Line Lender, the Issuing Lender, and each Lender (each a
“Lending Party”) agree to keep confidential any information furnished or made available to it by any Credit Party pursuant to this Agreement and identified by such Credit Party as proprietary or confidential; provided that
nothing herein shall prevent any Lending Party from disclosing such information (a) to any other Lending Party or any Affiliate of any Lending Party, or any officer, director, employee, agent, or advisor of any Lending Party or Affiliate of any
Lending Party for purposes of administering, negotiating, considering, processing, implementing, syndicating, assigning, or evaluating the credit facilities provided herein and the transactions contemplated hereby, (b) to any other Person if
directly incidental to the administration of the credit facilities provided herein, (c) as required by any Legal Requirement, (d) upon the order of any court or administrative agency, (e) upon the request or demand of any regulatory
agency or authority, (f) that is or becomes available to the public or that is or becomes available to any Lending Party other than as a result of a disclosure by any other Lending Party prohibited by this Agreement, (g) in connection with
any litigation relating to this Agreement or any other Credit Document to which such Lending Party or any of its Affiliates may be a party, (h) to the extent necessary in connection with the exercise of any right or remedy under this Agreement
or any other Credit Document, and (i) to any actual or proposed participant or assignee, in each case, subject to provisions similar to those contained in this Section 9.8. NOTWITHSTANDING ANYTHING TO THE CONTRARY CONTAINED HEREIN,

Notices, Etc. All notices and other communications (other than Notices of Borrowing and Notices of Continuation or Conversion, which are governed by Article 2 of this 

  
 -74- 

 
Agreement) shall be in writing and hand delivered with written receipt, telecopied, sent by facsimile (with a hard copy sent as otherwise permitted in this Section 9.9), sent by a nationally
recognized overnight courier, or sent by certified mail, return receipt requested as follows: if to a Credit Party, as specified on Schedule II and if to any Lender, the Swing Line Lender, or the Issuing Lender, at its credit contact specified under
its name on Schedule II. Each party may change its notice address by written notification to the other parties. All such notices and communications shall be effective when delivered, except that notices and communications to any Lender, Swing Line
Lender, or the Issuing Lender pursuant to Article 2 shall not be effective until received and, in the case of telecopy, such receipt is confirmed by such Lender, Swing Line Lender or Issuing Lender, as applicable, verbally or in writing. 

Section 9.10 Business Loans. Each Credit Party warrants and represents that the Obligations evidenced by the Notes are and shall
be for business, commercial, investment or other similar purposes and not primarily for personal, family, household or agricultural use, as such terms are used in Chapter One (“Chapter One”) of the Texas Credit Code. At all such times, if
any, as Chapter One shall establish a Maximum Rate, the Maximum Rate shall be the “indicated rate ceiling” (as such term is defined in Chapter One) from time to time in effect. 

Section 9.11 Usury Not Intended. It is the intent of each Credit Party and each Lender in the execution and performance of this
Agreement and the other Credit Documents to contract in strict compliance with applicable usury laws, including conflicts of law concepts, governing the Advances of each Lender including such applicable laws of the State of Texas, if any, and the
United States of America from time to time in effect. In furtherance thereof, the Lenders and the Credit Parties stipulate and agree that none of the terms and provisions contained in this Agreement or the other Credit Documents shall ever be
construed to create a contract to pay, as consideration for the use, forbearance or detention of money, interest at a rate in excess of the Maximum Rate and that for purposes of this Agreement “interest” shall include the aggregate of all
charges which constitute interest under such laws that are contracted for, charged or received under this Agreement; and in the event that, notwithstanding the foregoing, under any circumstances the aggregate amounts taken, reserved, charged,
received or paid on the Advances, include amounts which by applicable law are deemed interest which would exceed the Maximum Rate, then such excess shall be deemed to be a mistake and each Lender receiving same shall credit the same on the principal
of its Notes (or if such Notes shall have been paid in full, refund said excess to the Borrower). In the event that the maturity of the Notes are accelerated by reason of any election of the holder thereof resulting from any Event of Default under
this Agreement or otherwise, or in the event of any required or permitted prepayment, then such consideration that constitutes interest may never include more than the Maximum Rate, and excess interest, if any, provided for in this Agreement or
otherwise shall be canceled automatically as of the date of such acceleration or prepayment and, if theretofore paid, shall be credited on the applicable Notes (or, if the applicable Notes shall have been paid in full, refunded to the Borrower of
such interest). In determining whether or not the interest paid or payable under any specific contingencies exceeds the Maximum Rate, the Credit Parties and the Lenders shall to the maximum extent permitted under applicable law amortize, prorate,
allocate and spread in equal parts during the period of the full stated term of the Notes all amounts considered to be interest under applicable law at any time contracted for, charged, received or reserved in connection with the Obligations. The
provisions of this Section shall control over all other provisions of this Agreement or the other Credit Documents which may be in apparent conflict herewith. 

Section 9.12 Usury Recapture. In the event the rate of interest chargeable under this Agreement at any time is greater than the
Maximum Rate, the unpaid principal amount of the Advances shall bear interest at the Maximum Rate until the total amount of interest paid or accrued on the Advances equals the amount of interest which would have been paid or accrued on the Advances
if the stated rates of interest set forth in this Agreement had at all times been in effect. In the event, upon payment in full of the Advances, the total amount of interest paid or accrued under the terms of this Agreement and the

  
 -75- 

 
Advances is less than the total amount of interest which would have been paid or accrued if the rates of interest set forth in this Agreement had, at all times, been in effect, then the Borrower
shall, to the extent permitted by applicable law, pay the Administrative Agent for the account of the Lenders an amount equal to the difference between (i) the lesser of (A) the amount of interest which would have been charged on its
Advances if the Maximum Rate had, at all times, been in effect and (B) the amount of interest which would have accrued on its Advances if the rates of interest set forth in this Agreement had at all times been in effect and (ii) the amount
of interest actually paid under this Agreement on its Advances. In the event the Lenders ever receive, collect or apply as interest any sum in excess of the Maximum Rate, such excess amount shall, to the extent permitted by law, be applied to the
reduction of the principal balance of the Advances, and if no such principal is then outstanding, such excess or part thereof remaining shall be paid to the Borrower. 

Section 9.13 Governing Law. This Agreement, the Notes and the other Credit Documents (unless otherwise expressly provided therein)
shall be governed by, and construed and enforced in accordance with, the laws of the State of Texas. Without limiting the intent of the parties set forth above, (a) Chapter 346 of the Texas Finance Code, as amended (relating to revolving loans
and revolving tri-party accounts (formerly Tex. Rev. Civ. Stat. Ann. Art. 5069, Ch. 15)), shall not apply to this Agreement, the Notes, or the transactions contemplated hereby and (b) to the extent that any Lender may be subject to Texas law
limiting the amount of interest payable for its account, such Lender shall utilize the indicated (weekly) rate ceiling from time to time in effect. Each Letter of Credit shall be governed by either (i) the Uniform Customs and Practice for
Documentary Credits (2007 Revision), International Chamber of Commerce Publication No. 600, or (ii) the International Standby Practices (ISP98), International Chamber of Commerce Publication No. 590, in either case, including any
subsequent revisions thereof approved by a Congress of the International Chamber of Commerce and adhered to by the Issuing Lender. 

Section 9.14 Submission to Jurisdiction. Each Credit Party hereby irrevocably submits to the jurisdiction of any Texas state or
federal court sitting in Houston, Texas in any action or proceeding arising out of or relating to this Agreement or the other Credit Documents, and each Credit Party hereby irrevocably agrees that all claims in respect of such action or proceeding
may be heard and determined in such court. Each Credit Party hereby unconditionally and irrevocably waives, to the fullest extent it may effectively do so, any right it may have to the defense of an inconvenient forum to the maintenance of such
action or proceeding. Each Credit Party hereby agrees that service of copies of the summons and complaint and any other process which may be served in any such action or proceeding may be made by mailing or delivering a copy of such process to such
Credit Party at its address set forth in this Agreement. Each Credit Party hereby 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 Section shall affect the rights of any Lender to serve legal process in any other manner permitted by the law or affect the right of any Lender to bring any action or proceeding against any Credit Party or its
Property in the courts of any other jurisdiction. 
 Section 9.15 Execution in Counterparts. This Agreement may be executed in
any number of counterparts and by different parties hereto in separate counterparts, each of which when so executed shall be deemed to be an original and all of which taken together shall constitute one and the same agreement. 

Section 9.16 Waiver of Jury. EACH CREDIT PARTY, THE LENDERS, THE ADMINISTRATIVE AGENT, THE ISSUING LENDER, AND THE SWING LINE
LENDER HEREBY IRREVOCABLY WAIVE ANY AND ALL RIGHT TO TRIAL BY JURY IN RESPECT OF ANY LEGAL PROCEEDING ARISING OUT OF OR RELATING TO THIS AGREEMENT, ANY OTHER CREDIT DOCUMENT, OR ANY OF THE TRANSACTIONS CONTEMPLATED HEREBY.

 Section 9.17 USA Patriot Act. Each Lender that is subject to the Patriot Act and the
Administrative Agent (for itself and not on behalf of any Lender) hereby notifies each Credit Party that pursuant to the requirements of the Patriot Act it is required to obtain, verify and record information that identifies such Credit Party, which
information includes the name and address of such Credit Party and other information that will allow such Lender or the Administrative Agent, as applicable, to identify such Credit Party in accordance with the Patriot Act. 

PURSUANT TO SECTION 26.02 OF THE TEXAS BUSINESS AND COMMERCE CODE, A LOAN AGREEMENT IN WHICH THE AMOUNT INVOLVED IN THE LOAN AGREEMENT
EXCEEDS $50,000 IN VALUE IS NOT ENFORCEABLE UNLESS THE LOAN AGREEMENT IS IN WRITING AND SIGNED BY THE PARTY TO BE BOUND OR THAT PARTY’S AUTHORIZED REPRESENTATIVE. 

THE RIGHTS AND OBLIGATIONS OF THE PARTIES TO AN AGREEMENT SUBJECT TO THE PRECEDING PARAGRAPH SHALL BE DETERMINED SOLELY FROM THE WRITTEN
LOAN AGREEMENT, AND ANY PRIOR ORAL AGREEMENTS BETWEEN THE PARTIES ARE SUPERSEDED BY AND MERGED INTO THE LOAN AGREEMENT. THIS WRITTEN AGREEMENT AND THE CREDIT DOCUMENTS, AS DEFINED IN THIS AGREEMENT, REPRESENT THE FINAL AGREEMENT AMONG THE PARTIES
WITH RESPECT TO THE SUBJECT MATTERS SET FORTH HEREIN AND MAY NOT BE CONTRADICTED BY EVIDENCE OF PRIOR, CONTEMPORANEOUS, OR SUBSEQUENT ORAL AGREEMENTS OF THE PARTIES. 

THERE ARE NO UNWRITTEN ORAL AGREEMENTS BETWEEN THE PARTIES.

Pricing Schedule 
 During the
Alternative Covenant Period, the Applicable Margin with respect to Commitment Fee, Revolving Advances, and Swing Line Advances shall be determined in accordance with the following Table A: 

TABLE A 
  

									
	 LIBO

Advances
	 	Base Rate
Advances	 	 	Commitment Fee	 
	4.00%	 	 	3.00	% 	 	 	0.50	% 

 All other times, the Applicable Margin with respect to Commitment Fee, Revolving Advances, and Swing Line Advances shall be
determined in accordance with the following Table B based on the Borrower’s Leverage Ratio as reflected in the Compliance Certificate delivered in connection with the financial statements most recently delivered pursuant to Section 5.2
(commencing with the financial statements and Compliance Certificate delivered for the fiscal quarter ending March 31, 2017). Adjustments, if any, to such Applicable Margin shall be effective on the date the Administrative Agent receives the
applicable financial statements and corresponding Compliance Certificate as required by the terms of this Agreement. If the Borrower fails to deliver the financial statements and corresponding Compliance Certificate to the Administrative Agent at
the time required pursuant to Section 5.2, then effective as of the date such financial statements and Compliance Certificate were required to the delivered pursuant to Section 5.2, the Applicable Margin with respect to Commitment Fee,
Revolving Advances, and Swing Line Advances shall be determined at Level III and shall remain at such level until the date such financial statements and corresponding Compliance Certificate are so delivered by the Borrower. For the avoidance of
doubt, the failure to deliver the financial statements and corresponding Compliance Certificate for the fiscal quarter ending March 31, 2017 shall result in the continuation of the Alternative Covenant Period (and therefore the application of
