proving to be forged, fraudulent or invalid in any respect or any statement therein being untrue or inaccurate in any respect, (iii) payment by the Issuing Bank under a Letter of Credit against presentation of a draft or other document that
does not comply with the terms of such Letter of Credit, or (iv) any other event or circumstance whatsoever, whether or not similar to any of the foregoing, that might, but for the provisions of

  
 29 

 
this Section, constitute a legal or equitable discharge of, or provide a right of setoff against, the Borrower’s obligations hereunder. Neither the Administrative Agent, the Lenders nor the
Issuing Bank, nor any of their Related Parties, shall have any liability or responsibility by reason of or in connection with the issuance or transfer of any Letter of Credit or any payment or failure to make any payment thereunder (irrespective of
any of the circumstances referred to in the preceding sentence), or any error, omission, interruption, loss or delay in transmission or delivery of any draft, notice or other communication under or relating to any Letter of Credit (including any
document required to make a drawing thereunder), any error in interpretation of technical terms or any consequence arising from causes beyond the control of the Issuing Bank; provided that the foregoing shall not be construed to excuse the Issuing
Bank from liability to the Borrower to the extent of any direct damages (as opposed to special, indirect, consequential or punitive damages, claims in respect of which are hereby waived by the Borrower to the extent permitted by applicable law)
suffered by the Borrower that are caused by the Issuing Bank’s failure to exercise care when determining whether drafts and other documents presented under a Letter of Credit comply with the terms thereof. The parties hereto expressly agree
that, in the absence of gross negligence or willful misconduct on the part of the Issuing Bank (as finally determined by a court of competent jurisdiction), the Issuing Bank shall be deemed to have exercised care in each such determination. In
furtherance of the foregoing and without limiting the generality thereof, the parties agree that, with respect to documents presented which appear on their face to be in substantial compliance with the terms of a Letter of Credit, the Issuing Bank
may, in its sole discretion, either accept and make payment upon such documents without responsibility for further investigation, regardless of any notice or information to the contrary, or refuse to accept and make payment upon such documents if
such documents are not in strict compliance with the terms of such Letter of Credit. 
 (g)    Disbursement
Procedures. The Issuing Bank shall, promptly following its receipt thereof, examine all documents purporting to represent a demand for payment under a Letter of Credit. The Issuing Bank shall promptly notify the Administrative Agent and the
Borrower by telephone (confirmed by telecopy) of such demand for payment and whether the Issuing Bank has made or will make an LC Disbursement thereunder; provided that any failure to give or delay in giving such notice shall not relieve the
Borrower of its obligation to reimburse the Issuing Bank and the Revolving Lenders with respect to any such LC Disbursement. 

(h)    Interim Interest. If the Issuing Bank shall make any LC Disbursement, then, unless the Borrower shall
reimburse such LC Disbursement in full on the date such LC Disbursement is made, the unpaid amount thereof shall bear interest, for each day from and including the date such LC Disbursement is made to but excluding the date that the reimbursement is
due and payable at the rate per annum then applicable to Loans and such interest shall be due and payable on the date when such reimbursement is payable; provided that, if the Borrower fails to reimburse such LC Disbursement when due pursuant to
Section 2.04(e), then Section 2.12(b) shall apply. Interest accrued pursuant to this Section 2.04(h) shall be for the account of the Issuing Bank, except that interest accrued on and after the date of payment by any Revolving
Lender pursuant to Section 2.04(e) to reimburse the Issuing Bank shall be for the account of such Lender to the extent of such payment. 

  
 30 

 (i)    Replacement of the Issuing Bank. The Issuing Bank may be
replaced at any time by written agreement among the Borrower, the Administrative Agent, the replaced Issuing Bank and the successor Issuing Bank. The Administrative Agent shall notify the Lenders of any such replacement of the Issuing Bank. At the
time any such replacement shall become effective, the Borrower shall pay all unpaid fees accrued for the account of the replaced Issuing Bank pursuant to Section 2.11(b). From and after the effective date of any such replacement, (i) the
successor Issuing Bank shall have all the rights and obligations of the Issuing Bank under this Agreement with respect to Letters of Credit to be issued thereafter and (ii) references herein to the term “Issuing Bank” shall be deemed
to refer to such successor or to any previous Issuing Bank, or to such successor and all previous Issuing Banks, as the context shall require. After the replacement of an Issuing Bank hereunder, the replaced Issuing Bank shall remain a party hereto
and shall continue to have all the rights and obligations of an Issuing Bank under this Agreement with respect to Letters of Credit issued by it prior to such replacement, but shall not be required to issue additional Letters of Credit. 

(j)    Cash Collateralization. If any Event of Default shall occur and be continuing, on the Business Day that the
Borrower receives notice from the Administrative Agent or the Required Lenders (or, if the maturity of the Loans has been accelerated, Revolving Lenders with LC Exposure representing greater than 66-2/3% of
the total LC Exposure) demanding the deposit of cash collateral pursuant to this Section 2.04(j), the Borrower shall deposit in an account with the Administrative Agent, in the name of the Administrative Agent and for the benefit of the
Lenders, an amount in cash equal to the LC Exposure as of such date plus any accrued and unpaid interest thereon; provided that the obligation to deposit such cash collateral shall become effective immediately, and such deposit shall become
immediately due and payable, without demand or other notice of any kind, upon the occurrence of any Event of Default described in clauses (g) or (h) of Article VII. The Borrower also shall deposit cash collateral pursuant
to this Section 2.04(j) as and to the extent required by Section 2.10(b). Each such deposit shall be held by the Administrative Agent as collateral for the payment and performance of the obligations of the Borrower under this
Agreement. The Administrative Agent shall have exclusive dominion and control, including the exclusive right of withdrawal, over such account. Other than any interest earned on the investment of such deposits, which investments shall be made at the
option and sole discretion of the Administrative Agent and at the Borrower’s risk and expense, such deposits shall not bear interest. Interest or profits, if any, on such investments shall accumulate in such account. Moneys in such account
shall be applied by the Administrative Agent to reimburse the Issuing Bank for LC Disbursements for which it has not been reimbursed and, to the extent not so applied, shall be held for the satisfaction of the reimbursement obligations of the
Borrower for the LC Exposure at such time or, if the maturity of the Loans has been accelerated (but subject to the consent of Revolving Lenders with LC Exposure representing greater than 66-2/3% of the total
LC Exposure), be applied to satisfy other obligations of the Borrower under this Agreement. If the Borrower is required to provide an amount of cash collateral hereunder as a result of the occurrence of an Event of Default, such amount (to the
extent not applied as aforesaid) shall be returned to the Borrower within three (3) Business Days after all Events of Default have been cured or waived. If the Borrower is required to provide an amount of cash collateral hereunder pursuant to
Section 2.10(b), such amount (to the extent not 

  
 31 

 
applied as aforesaid) shall be returned to the Borrower as and to the extent that, after giving effect to such return, the Borrower would remain in compliance with Section 2.10(b) and no
Default shall have occurred and be continuing. 
 (k)    Subject to the appointment and acceptance of a successor
Issuing Bank, the Issuing Bank may resign as the Issuing Bank at any time upon thirty days’ prior written notice to the Administrative Agent, the Borrower and the Lenders, in which case, such Issuing Bank shall be replaced in accordance with
Section 2.04(i) above. 
 SECTION 2.05 Funding of Borrowings. 

(a)    Each Lender shall make each Loan to be made by it hereunder on the proposed date thereof solely by wire transfer of
immediately available funds by 12:00 noon, Houston, Texas time, to the account of the Administrative Agent most recently designated by it for such purpose by notice to the Lenders. Except in respect of the provisions of this Agreement covering the
reimbursement of Letters of Credit, the Administrative Agent will make such Loans available to the Borrower by promptly crediting the funds so received in the aforesaid account of the Administrative Agent to an account of the Borrower maintained
with the Administrative Agent in Houston, Texas and designated by the Borrower in the applicable Borrowing Request; provided that Revolving Loans made to finance the reimbursement of an LC Disbursement as provided in Section 2.04(e) shall be
remitted by the Administrative Agent to the Issuing Bank. 
 (b)    Unless the Administrative Agent shall have received
notice from a Lender prior to the proposed date of any Borrowing that such Lender will not make available to the Administrative Agent such Lender’s share of such Borrowing, the Administrative Agent may assume that such Lender has made such
share available on such date in accordance with Section 2.05(a) and may, in reliance upon such assumption, make available to the Borrower a corresponding amount. If a Lender has not in fact made its share of the applicable Borrowing available
to the Administrative Agent, then the applicable Lender and the Borrower severally agree to pay to the Administrative Agent forthwith on demand such corresponding amount with interest thereon, for each day from and including the date such amount is
made available to the Borrower to but excluding the date of payment to the Administrative Agent, at (i) in the case of such Lender, the greater of the Federal Funds Effective Rate and a rate determined by the Administrative Agent in accordance
with banking industry rules on interbank compensation or (ii) in the case of the Borrower, the interest rate applicable to Loans. If such Lender pays such amount to the Administrative Agent, then such amount shall constitute such Lender’s
Loan included in such Borrowing. 
 SECTION 2.06 [Intentionally Left Blank]. 

SECTION 2.07 Termination and Reduction and Increase of Commitments. 

(a)    Unless previously terminated, (i) the Advance Loan Commitments shall be reduced by the amount of any Advance
Loans made and shall terminate at 5:00 p.m., Houston, Texas time on the last day of the Advance Loan Availability Period and (ii) the Revolving Commitments shall terminate on the Revolving Maturity Date. 

  
 32 

 (b)    The Borrower may at any time terminate, or from time to time reduce,
the Commitments of any Class; provided that (i) each reduction of the Commitments of any Class shall be in an amount that is an integral multiple of $500,000 and (ii) the Borrower shall not terminate or reduce the Revolving
Commitments if, after giving effect to any concurrent prepayment of the Revolving Loans in accordance with Section 2.10, the Total Revolving Exposure would exceed the lesser of (x) the total Revolving Commitments or
(y) the then current Borrowing Base. 
 (c)    The Borrower shall notify the Administrative Agent of any election
to terminate or reduce the Commitments under Section 2.07(b), at least three (3) Business Days prior to the effective date of such termination or reduction, specifying such election and the effective date thereof. Promptly following
receipt of any notice, the Administrative Agent shall advise the Lenders of the contents thereof. Each notice delivered by the Borrower pursuant to this Section shall be irrevocable; provided that a notice of termination of the Revolving Commitments
delivered by the Borrower may state that such notice is conditioned upon the effectiveness of other credit facilities, in which case such notice may be revoked by the Borrower (by notice to the Administrative Agent on or prior to the specified
effective date) if such condition is not satisfied. Any termination or reduction of the Commitments of any Class shall be permanent. Each reduction of the Commitments of any Class shall be made ratably among the Lenders in accordance with
their respective Commitments of such Class. 
 (d)    At any time prior to the expiration of the Revolving Availability
Period, and so long as no Default or Event of Default shall have occurred which is continuing, the Borrower may elect to increase the aggregate of the Revolving Commitments to an amount not exceeding $2,000,000 minus any reductions in the
Revolving Commitments pursuant to Section 2.07(b), provided that (i) the Borrower shall give at least fifteen (15) Business Days’ prior written notice of such increase to the Administrative Agent and each existing Lender,
(ii) each existing Lender shall have the right (but not the obligation) to subscribe to its pro rata share of the proposed increase in the Revolving Commitments by giving written notice of such election to the Borrower and the Administrative
Agent within ten (10) Business Days after receipt of a notice from the Borrower as above described and only if an existing Lender does not exercise such election may the Borrower elect to add a new Lender, (iii) no Lender shall be required
to increase its Revolving Commitment unless it shall have expressly agreed to such increase in writing, (iv) the addition of new Lenders shall be subject to the terms and provisions of Section 9.04 as if such new
Lenders were acquiring an interest in the Loans by assignment from an existing Lender (to the extent applicable, i.e. required approvals, minimum amounts and the like), (v) the Borrower shall execute and deliver such additional or replacement Notes
and such other documentation (including evidence of proper authorization) as may be reasonably requested by the Administrative Agent, any new Lender or any Lender which is increasing its Revolving Commitment, (vi) no Lender shall have any right
to decrease its Revolving Commitment as a result of such increase of the aggregate amount of the Revolving 

  
 33 

 
Commitments, (vii) the Administrative Agent shall have no obligation to arrange, find or locate any Lender or new bank or financial institution to participate in any unsubscribed portion of
such increase in the aggregate committed amount of the Revolving Commitments, (viii) such option to increase the Revolving Commitments may only be exercised once and (ix) the consent of a Lenders shall be required for any increase of
such Lender’s Revolving Commitment (such consent to be given or denied in its sole discretion and subject to such terms as it may then require). The Borrower shall be required to pay (or to reimburse each applicable Lender for) any breakage
costs incurred by any Lender in connection with the need to reallocate existing Loans among the Lenders following any increase in the Revolving Commitments pursuant to this provision. 

SECTION 2.08 Repayment of Loans; Evidence of Debt. 

(a)    The Borrower hereby unconditionally promises to pay (i) to the Administrative Agent for the account of each
Lender the then unpaid principal amount of each Revolving Loan of such Lender on the Revolving Maturity Date and (ii) to the Administrative Agent for the account of each Lender the then unpaid principal amount of each Advance Loan of such
Lender as provided in Section 2.09. 
 (b)    Each Lender shall maintain in accordance with
its usual practice an account or accounts evidencing the indebtedness of the Borrower to such Lender resulting from each Loan made by such Lender, including the amounts of principal and interest payable and paid to such Lender from time to time
hereunder. 
 (c)    The Administrative Agent shall maintain accounts in which it shall record (i) the amount of
each Loan made hereunder and the Class thereof, (ii) the amount of any principal or interest due and payable or to become due and payable from the Borrower to each Lender hereunder and (iii) the amount of any sum received by the
Administrative Agent hereunder for the account of the Lenders and each Lender’s share thereof. 
 (d)    The
entries made in the accounts maintained pursuant to Sections 2.08(b) or 2.08(c) shall be prima facie evidence of the existence and amounts of the obligations recorded therein; provided that the failure of any Lender or the
Administrative Agent to maintain such accounts or any error therein shall not in any manner affect the obligation of the Borrower to repay the Loans in accordance with the terms of this Agreement. 

SECTION 2.09 Amortization of Advance Loans. 

(a)    On December 5, 2017 and on the fifth (5th) day of each calendar month thereafter prior to the Advance Loan
Maturity Date, the Borrower shall repay Advance Loan Borrowings in the aggregate principal amount equal to 1/48th of the aggregate unpaid principal balance of the Advance Loans as of the last day of the Advance Loan Availability Period. 

(b)    To the extent not previously paid, all Advance Loans shall be due and payable on the Advance Loan Maturity Date.

  
 34 

 (c)    Each repayment of a Borrowing shall be applied ratably to the Loans
included in the repaid Borrowing. Repayments of Advance Loan Borrowings shall be accompanied by accrued interest on the amount repaid. 

SECTION 2.10 Prepayment of Loans. 

(a)    The Borrower shall have the right at any time and from time to time to prepay any Borrowing in whole or in part,
subject to the requirements of this Section. Each prepayment of an Advance Loan shall be in an amount equal to the lesser of the entire unpaid principal balance of the Advance Loans or an integral multiple of $100,000. Each prepayment of an Advance
Loan shall require at least three (3) Business Days’ advance written notice to the Administrative Agent. 

(b)    In the event and on such occasion that the sum of the Revolving Exposures exceeds the lesser of (x) the total
Revolving Commitments or (y) the then current Borrowing Base, the Borrower shall prepay Revolving Borrowings (or, if no such Borrowings are outstanding, deposit cash collateral in an account with the Administrative Agent pursuant to Section
2.04(j)) in an aggregate amount equal to such excess. 
 (c)    If for any reason (i) any Advance Loans are
optionally prepaid pursuant to Section 2.10(a), or (ii) any Advance Loans are required to be mandatorily prepaid pursuant to Article VII, the Borrower agrees to pay to Administrative Agent, for the pro rata benefit of Lenders,
upon the effective date of such payment, a prepayment premium in the amount (the “Prepayment Premium”) equal to: 
  

									
	 	 	 Amount
	 	 	  	 Period
	  	 
		 	0.50% of the amount prepaid (in the case of optional prepayments) or of the amount required to be prepaid (in the case of mandatory prepayments	 		  	From the Effective Date to and including the second anniversary of the Effective Date	  	
					
		 	0.00% of the amount prepaid (in the case of optional prepayments) or of the amount required to be prepaid (in the case of mandatory prepayments	 		  	From and after the date following the second anniversary of the Effective Date	  	

 (d)    Any prepayment of an Advance Loan Borrowing shall be applied to reduce all of the
subsequent scheduled repayments of the Advance Loan Borrowings in inverse order of their maturity. 

  
 35 

 (e)    Prior to any optional or mandatory prepayment of Borrowings hereunder,
the Borrower shall select the Borrowing or Borrowings to be prepaid and shall specify such selection in the notice of such prepayment pursuant to this Section. 

(f)    The Borrower shall notify the Administrative Agent by telephone (confirmed by telecopy) of any prepayment hereunder
not later than 11:00 a.m., Houston, Texas time, one (1) Business Day before the date of prepayment. Each such notice shall be irrevocable and shall specify the prepayment date, the principal amount of each Borrowing or portion thereof to be
prepaid and, in the case of a mandatory prepayment, a reasonably detailed calculation of the amount of such prepayment; provided that, if a notice of optional prepayment is given in connection with a conditional notice of termination of the
Revolving Commitments as contemplated by Section 2.07, then such notice of prepayment may be revoked if such notice of termination is revoked in accordance with Section 2.07. Promptly following
receipt of any such notice, the Administrative Agent shall advise the Lenders of the contents thereof. Each partial prepayment of any Borrowing shall be in an amount that would be permitted in the case of an advance of a Borrowing as provided in
Section 2.02, except as necessary to apply fully the required amount of a mandatory prepayment. 

(g)    All Swap Agreements and agreements governing Banking Services between Borrower and any Lender (or any Affiliate of
a Lender) are independent agreements governed by the written provisions of said Swap Agreements and said agreements governing Banking Services, which will remain in full force and effect, unaffected by any repayment, prepayment, acceleration,
reduction, increase or change in the terms of the Obligations, except as otherwise expressly provided in said Swap Agreements and said agreements governing Banking Services, and any payoff statement relating to the Obligations shall not apply to
said Swap Agreements or agreements governing Banking Services except as otherwise expressly provided in such payoff statement. 
 SECTION
2.11 Fees. 
 (a)    The Borrower agrees to pay to the Administrative Agent for the account of each Lender a
commitment fee, which shall accrue at the Applicable Rate on the average daily unused amount of the Revolving Commitment of such Lender during the period from and including the date hereof to but excluding the date on which such Revolving Commitment
terminates. Accrued commitment fees shall be payable in arrears on the 5th day of each calendar month (commencing on January 5, 2017) and on the date on which the Revolving Commitments terminate. All commitment fees shall be computed on the
basis of a year of 360 days and shall be payable for the actual number of days elapsed (including the first day but excluding the last day). For purposes of computing such commitment fees, a Revolving Commitment of a Lender shall be deemed to be
used to the extent of the outstanding Revolving Loans and LC Exposure of such Lender for purposes of calculating fees due under this Section 2.11(a)). 

(b)    The Borrower agrees to pay (i) to the Administrative Agent for the account of each Revolving Lender a
participation fee with respect to its participations in Letters of Credit, 

  
 36 

 
which shall accrue at the same Applicable Rate used to determine the interest rate applicable to Loans on the average daily amount of such Lender’s LC Exposure (excluding any portion thereof
attributable to unreimbursed LC Disbursements) during the period from and including the Effective Date to but excluding the later of the date on which such Lender’s Revolving Commitment terminates and the date on which such Lender ceases to
have any LC Exposure (provided, however, that in no event shall the per annum fee for any single Letter of Credit be less than $500, payable quarterly in arrears in installments of $125 per quarter) and (ii) at any time or times that there
shall be two or more Lenders, to the Issuing Bank a fronting fee, which shall accrue at the rate of 0.125% per annum on the average daily amount of the LC Exposure (excluding any portion thereof attributable to unreimbursed LC Disbursements) during
the period from and including the Effective Date to but excluding the later of the date of termination of the Revolving Commitments and the date on which there ceases to be any LC Exposure, as well as the Issuing Bank’s standard fees with
respect to the amendment, renewal or extension of any Letter of Credit or processing of drawings thereunder. Participation fees and fronting fees shall be payable in arrears on the 5th day of each calendar month (commencing on January 5, 2017);
provided that all such fees shall be payable on the date on which the Revolving Commitments terminate and any such fees accruing after the date on which the Revolving Commitments terminate shall be payable on demand. Any other fees payable to the
Issuing Bank pursuant to this Section 2.11(b) shall be payable within 10 days after demand. All participation fees and fronting fees shall be computed on the basis of a year of 360 days and shall be payable for the actual number of days
elapsed (including the first day but excluding the last day). 
 (c)    If any payment required hereunder is more than
ten (10) days late, Borrower will (subject to the provisions of Section 9.12 hereof) pay a delinquency charge in an amount equal to the greater of (i) 5.00% of the delinquent payment up to the maximum amount of $1,500
or (ii) $25.00. 
 (d)    The Borrower agrees to pay to the Administrative Agent, for its own account, fees payable in
the amounts and at the times separately agreed upon between the Borrower and the Administrative Agent. 
 (e)    All
fees payable hereunder shall be paid on the dates due, in immediately available funds, to the Administrative Agent (or to the Issuing Bank, in the case of fees payable to it) for distribution, in the case of commitment fees and participation fees,
to the Lenders entitled thereto. Fees paid shall not be refundable under any circumstances. 
 SECTION 2.12 Interest. 

(a)    The Loans shall bear interest at the lesser of (i) the Adjusted LIBO Rate plus the Applicable Rate or
(ii) the Ceiling Rate. 
 (b)    Notwithstanding the foregoing, if any Event of Default has occurred which is
continuing: 

  
 37 

	 	(i)	any overdue amount shall bear interest per annum that is (x) in the case of overdue principal, the rate that would otherwise be applicable thereto plus 5%, not to exceed the Ceiling Rate, or (x) in the
case of any other overdue amount, including overdue interest, to the extent permitted by applicable law, the rate applicable to Loans plus 5%, not to exceed the Ceiling Rate (in each case, after as well as before judgment); and

  

	 	(ii)	at the election of the Required Lenders, the entire unpaid principal balance of the Loans shall bear interest at the rate that would otherwise be applicable thereto plus 5%, not to exceed the Ceiling Rate (in
each case, after as well as before judgment). 

 (c)    Accrued interest on each Loan shall be payable in
arrears on each Interest Payment Date for such Loan and, in the case of Revolving Loans, upon termination of the Revolving Commitments; provided that (i) interest accrued pursuant to Section 2.12(b) shall be payable on demand, and
(ii) in the event of any repayment or prepayment of any Loan (other than a prepayment of a Revolving Loan prior to the end of the Revolving Availability Period), accrued interest on the principal amount repaid or prepaid shall be payable on the
date of such repayment or prepayment. 
 (d)    All interest hereunder shall be computed on the basis of a year of 360
days and shall be payable for the actual number of days elapsed (including the first day but excluding the last day). The applicable LIBO Rate shall be determined by the Administrative Agent, and such determination shall be conclusive absent
manifest error. 
 SECTION 2.13 [Intentionally Left Blank]. 

SECTION 2.14 [Intentionally Left Blank]. 

SECTION 2.15 [Intentionally Left Blank]. 

SECTION 2.16 Taxes. 

(a)    Any and all payments by or on account of any obligation of any Loan Party under any Loan Document shall be made
without deduction or withholding for any Taxes, except as required by applicable law. If any applicable law (as determined in the good faith discretion of an applicable withholding agent) requires the deduction or withholding of any Tax from any
such payment by a withholding agent, then the applicable withholding agent shall be entitled to make such deduction or withholding and shall timely pay the full amount deducted or withheld to the relevant Governmental Authority in accordance with
applicable law and, if such Tax is an Indemnified Tax, then the sum payable by the applicable Loan Party shall be increased as necessary so that after such deduction or withholding has been made (including such deductions and withholdings applicable
to additional sums payable under this Section) the applicable Recipient receives an amount equal to the sum it would have received had no such deduction or withholding been made. 

  
 38 

 (b)    The Loan Parties shall timely pay to the relevant Governmental
Authority in accordance with applicable law, or at the option of the Administrative Agent timely reimburse it for, Other Taxes. 

(c)    As soon as practicable after any payment of Taxes by any Loan Party to a Governmental Authority pursuant to this
Section, such Loan Party shall deliver to the Administrative Agent the original or a certified copy of a receipt issued by such Governmental Authority evidencing such payment, a copy of the return reporting such payment or other evidence of such
payment reasonably satisfactory to the Administrative Agent. 
 (d)    The Borrower shall indemnify each Recipient,
within 10 days after demand therefor, for the full amount of any Indemnified Taxes (including Indemnified Taxes imposed or asserted on or attributable to amounts payable under this Section) payable or paid by such Recipient or required to be
withheld or deducted from a payment to such Recipient and any reasonable expenses arising therefrom or with respect thereto, whether or not such Indemnified Taxes were correctly or legally imposed or asserted by the relevant Governmental Authority.
A certificate as to the amount of such payment or liability delivered to the Borrower by a Lender (with a copy to the Administrative Agent), or by the Administrative Agent on its own behalf or on behalf of a Lender, shall be conclusive absent
manifest error. 
 (e)    Each Lender shall severally indemnify the Administrative Agent, within 10 days after demand
therefor, for (i) any Indemnified Taxes attributable to such Lender (but only to the extent that the Borrower has not already indemnified the Administrative Agent for such Indemnified Taxes and without limiting the obligation of the Borrower to
do so), (ii) any Taxes attributable to such Lender’s failure to comply with the provisions of Section 9.04(c) relating to the maintenance of a Participant Register and (iii) any Excluded Taxes attributable to such Lender, in each
case, that are payable or paid by the Administrative Agent in connection with any Loan Document, and any reasonable expenses arising therefrom or with respect thereto, whether or not such Taxes were correctly or legally imposed or asserted by the
relevant Governmental Authority. A certificate as to the amount of such payment or liability delivered to any Lender by the Administrative Agent shall be conclusive absent manifest error. Each Lender hereby authorizes the Administrative Agent to set
off and apply any and all amounts at any time owing to such Lender under any Loan Document or otherwise payable by the Administrative Agent to such Lender from any other source against any amount due to the Administrative Agent under this Section
2.16(e). 
 (f)    (i) Any Lender that is entitled to an exemption from or reduction of withholding Tax with respect
to payments made under any Loan Document shall deliver to the Borrower and the Administrative Agent, at the time or times reasonably requested by the Borrower or the Administrative Agent, such properly completed and executed documentation reasonably
requested by the Borrower or the Administrative Agent as will permit such payments to be made without withholding or at a reduced rate of withholding. In addition, any Lender, if reasonably requested by the Borrower or the Administrative Agent,
shall deliver such other documentation prescribed by applicable law or reasonably requested by the Borrower or the Administrative 

  
 39 

 
Agent as will enable the Borrower or the Administrative Agent to determine whether or not such Lender is subject to backup withholding or information reporting requirements. Notwithstanding
anything to the contrary in the preceding two sentences, the completion, execution and submission of such documentation (other than such documentation set forth in Sections 2.16(f)(ii)(A), (ii)(B) and (ii)(D) below) shall not be
required if in the relevant Lender’s reasonable judgment such completion, execution or submission would subject such Lender to any material unreimbursed cost or expense or would materially prejudice the legal or commercial position of such
Lender. 
 (ii)    Without limiting the generality of the foregoing, in the event that the Borrower is a
U.S. Person: 
 (A)    any Lender that is a U.S. Person shall deliver to the Borrower and the
Administrative Agent on or prior to the date on which such Lender becomes a Lender under this Agreement (and from time to time thereafter upon the reasonable request of the Borrower or the Administrative Agent), an executed IRS Form W-9 certifying that such Lender is exempt from U.S. Federal backup withholding tax; 

(B)    any Foreign Lender shall, to the extent it is legally entitled to do so, deliver to the Borrower and
the Administrative Agent (in such number of copies as shall be requested by the recipient) on or prior to the date on which such Foreign Lender becomes a Lender under this Agreement (and from time to time thereafter upon the reasonable request of
the Borrower or the Administrative Agent), whichever of the following is applicable: 
  

	 	(1)	in the case of a Foreign Lender claiming the benefits of an income tax treaty to which the United States is a party (x) with respect to payments of interest under any Loan Document, an executed IRS Form W-8BEN-E or IRS Form W-8BEN establishing an exemption from, or reduction of, U.S. Federal withholding Tax pursuant to the
“interest” article of such tax treaty and (y) with respect to any other applicable payments under any Loan Document, IRS Form W-8BEN-E or IRS Form W-8BEN establishing an exemption from, or reduction of, U.S. Federal withholding Tax pursuant to the “business profits” or “other income” article of such tax treaty; 

 

	 	(2)	in the case of a Foreign Lender claiming that its extension of credit will generate U.S. effectively connected income, an executed IRS Form W-8ECI; 

 

	 	(3)	 in the case of a Foreign Lender claiming the benefits of the exemption for portfolio interest under Section
881(c) of the Code,

(x) a certificate substantially in the form of Exhibit E-1 to the effect that such Foreign Lender is not a “bank” within the meaning of
Section 881(c)(3)(A) of the Code, a “10 percent shareholder” of the Borrower within the meaning of Section 881(c)(3)(B) of the Code, or a “controlled foreign corporation” described in Section 881(c)(3)(C) of the Code (a
“U.S. Tax Compliance Certificate”) and (y) an executed IRS Form W-8BEN-E or IRS Form W-8BEN; or

  

	 	(4)	to the extent a Foreign Lender is not the beneficial owner, an executed IRS Form W-8IMY, accompanied by IRS Form W-8ECI, IRS Form W-8BEN-E, IRS Form W-8BEN, a U.S. Tax Compliance Certificate substantially in the form of Exhibit
E-2 or Exhibit E-3, IRS Form W-9, and/or other certification documents from each beneficial owner, as applicable;
provided that if such Foreign Lender is a partnership and one or more direct or indirect partners of such Foreign Lender are claiming the portfolio interest exemption, such Foreign Lender may provide a U.S. Tax Compliance Certificate substantially
in the form of Exhibit E-4 on behalf of each such direct and indirect partner; 

(C)    any Foreign Lender shall, to the extent it is legally entitled to do so, deliver to the Borrower
and the Administrative Agent (in such number of copies as shall be requested by the recipient) on or prior to the date on which such Foreign Lender becomes a Lender under this Agreement (and from time to time thereafter upon the reasonable request
of the Borrower or the Administrative Agent), executed originals of any other form prescribed by applicable law as a basis for claiming exemption from or a reduction in U.S. Federal withholding Tax, duly completed, together with such supplementary
documentation as may be prescribed by applicable law to permit the Borrower or the Administrative Agent to determine the withholding or deduction required to be made; and 

(D)    if a payment made to a Lender under any Loan Document would be subject to U.S. Federal withholding
Tax imposed by FATCA if such Lender were to fail to comply with the applicable reporting requirements of FATCA (including those contained in Section 1471(b) or 1472(b) of the Code, as applicable), such Lender shall deliver to the Borrower and the
Administrative Agent at the time or times prescribed by law and at such time or times reasonably requested by the Borrower or the Administrative Agent such documentation prescribed by applicable law (including as prescribed by Section
1471(b)(3)(C)(i) of the Code) and such additional documentation reasonably requested by the Borrower or the Administrative Agent as may be necessary for the Borrower and the Administrative Agent to comply with their obligations under FATCA and to
determine that such Lender has complied with such Lender’s obligations under 

  
 41 

 
FATCA or to determine the amount to deduct and withhold from such payment. Solely for purposes of this clause (D), “FATCA” shall include any amendments made to FATCA after the
date of this Agreement. 
 Each Lender agrees that if any form or certification it previously delivered expires or becomes obsolete or
inaccurate in any respect, it shall update such form or certification or promptly notify the Borrower and the Administrative Agent in writing of its legal inability to do so. 

(g)    If any party determines, in its sole discretion exercised in good faith, that it has received a refund of any Taxes
as to which it has been indemnified pursuant to this Section (including by the payment of additional amounts pursuant to this Section), it shall pay to the indemnifying party an amount equal to such refund (but only to the extent of indemnity
payments made under this Section with respect to the Taxes giving rise to such refund), net of all out-of-pocket expenses (including Taxes) of such indemnified party and
without interest (other than any interest paid by the relevant Governmental Authority with respect to such refund). Such indemnifying party, upon the request of such indemnified party, shall repay to such indemnified party the amount paid over
pursuant to this Section 2.16(g) (plus any penalties, interest or other charges imposed by the relevant Governmental Authority) in the event that such indemnified party is required to repay such refund to such Governmental Authority.
Notwithstanding anything to the contrary in this Section 2.16(g), in no event will the indemnified party be required to pay any amount to an indemnifying party pursuant to this Section 2.16(g) the payment of which would place the
indemnified party in a less favorable net after-Tax position than the indemnified party would have been in if the Tax subject to indemnification and giving rise to such refund had not been deducted, withheld
or otherwise imposed and the indemnification payments or additional amounts with respect to such Tax had never been paid. This paragraph shall not be construed to require any indemnified party to make available its Tax returns (or any other
information relating to its Taxes that it deems confidential) to the indemnifying party or any other Person. 

(h)    Each party’s obligations under this Section shall survive the resignation or replacement of the Administrative
Agent or any assignment of rights by, or the replacement of, a Lender, the termination of the Commitments and the repayment, satisfaction or discharge of all obligations under any Loan Document. 

(i)    For purposes of this Section, the term “Lender” includes any Issuing Bank and the term “applicable
law” includes FATCA. 
 SECTION 2.17 Payments Generally; Pro Rata Treatment; Sharing of
Set-offs. 
 (a)     The Borrower shall make each payment required to be made
by it hereunder or under any other Loan Document (whether of principal, interest, fees or reimbursement of LC Disbursements, or of amounts payable under Section 2.16, or otherwise) prior to the time expressly required
hereunder or under such other Loan Document for such payment (or, if no 

  
 42 

 
such time is expressly required, prior to 2:00 p.m., Houston, Texas time), on the date when due, in immediately available funds, without set off, deduction or counterclaim. Any amounts received
after such time on any date may, in the discretion of the Administrative Agent, be deemed to have been received on the next succeeding Business Day for purposes of calculating interest thereon. All such payments shall be made to the Administrative
Agent at its offices at Woodforest National Bank-Loan Operations, P.O. Box 7889, The Woodlands, TX 77387-7889, except payments to be made directly to the Issuing Bank as expressly provided herein and except that payments pursuant to Sections
2.16 and 9.03 shall be made directly to the Persons entitled thereto and payments pursuant to other Loan Documents shall be made to the Persons specified therein. The Administrative Agent shall distribute any such payments received by it
for the account of any other Person to the appropriate recipient promptly following receipt thereof. If any payment under any Loan Document shall be due on a day that is not a Business Day, the date for payment shall be extended to the next
succeeding Business Day, and, in the case of any payment accruing interest, interest thereon shall be payable for the period of such extension. All payments under each Loan Document shall be made in dollars. 

(b)    If at any time insufficient funds are received by and available to the Administrative Agent to pay fully all
amounts of principal, unreimbursed LC Disbursements, interest and fees and other Obligations then due, such funds shall be applied (i) first, towards payment of interest and fees then due hereunder, ratably among the parties entitled thereto in
accordance with the amounts of interest and fees then due to such parties, and (ii) second, towards payment of principal and unreimbursed LC Disbursements and other Obligations then due, ratably among the parties entitled thereto in accordance
with the amounts of principal and unreimbursed LC Disbursements and other Obligations then due to such parties. 

(c)     If any Lender shall, by exercising any right of set off or counterclaim or otherwise, obtain payment in respect of
any principal of or interest on any of its Revolving Loans, Advance Loans or participations in LC Disbursements o, resulting in such Lender receiving payment of a greater proportion of the aggregate amount of its Revolving Loans, Advance Loans and
participations in LC Disbursements and accrued interest thereon than the proportion received by any other Lender, then the Lender receiving such greater proportion shall purchase (for cash at face value) participations in the Revolving Loans,
Advance Loans and participations in LC Disbursements of other Lenders to the extent necessary so that the benefit of all such payments shall be shared by the Lenders ratably in accordance with the aggregate amount of principal of and accrued
interest on their respective Revolving Loans, Advance Loans and participations in LC Disbursements; provided that (i) if any such participations are purchased and all or any portion of the payment giving rise thereto is recovered, such
participations shall be rescinded and the purchase price restored to the extent of such recovery, without interest, and (ii) the provisions of this Section 2.17(c) shall not be construed to apply to any payment made by the Borrower
pursuant to and in accordance with the express terms of this Agreement or any payment obtained by a Lender as consideration for the assignment of or sale of a participation in any of its Loans or participations in LC Disbursements to any assignee or
participant, other than to the Borrower or any other Loan Party or Affiliate thereof (as to which the provisions of this Section 2.17(c) shall apply). Each Lender agrees that it will not exercise

  
 43 

 
any right of set-off or counterclaim or otherwise obtain payment in respect of any Obligation owed to it other than principal of and interest accruing on
the Loans and participations in the LC Disbursements, unless all of the outstanding principal of and accrued interest on the Loans and LC Disbursements have been paid in full. The Borrower consents to the foregoing and agrees, to the extent it may
effectively do so under applicable law, that any Lender acquiring a participation pursuant to the foregoing arrangements may exercise against the Borrower rights of set-off and counterclaim with respect to
such participation as fully as if such Lender were a direct creditor of the Borrower in the amount of such participation. 

(d)    Unless the Administrative Agent shall have received notice from the Borrower prior to the date on which any payment
is due to the Administrative Agent for the account of the Lenders or the Issuing Bank hereunder that the Borrower will not make such payment, the Administrative Agent may assume that the Borrower has made such payment on such date in accordance
herewith and may, in reliance upon such assumption, distribute to the Lenders or the Issuing Bank, as the case may be, the amount due. If the Borrower has not in fact made such payment when due, then each of the Lenders or the Issuing Bank, as the
case may be, severally agrees to repay to the Administrative Agent forthwith on demand the amount so distributed to such Lender or Issuing Bank with interest thereon, for each day from and including the date such amount is distributed to it to but
excluding the date of payment to the Administrative Agent, at the greater of the Federal Funds Effective Rate and a rate determined by the Administrative Agent in accordance with banking industry rules on interbank compensation. 

(e)    If any Lender shall fail to make any payment required to be made by it pursuant to this Agreement, then the
Administrative Agent may, in its discretion (and notwithstanding any contrary provision hereof), (i) apply any amounts thereafter received by the Administrative Agent for the account of such Lender for the benefit of the Administrative Agent to
satisfy such Lender’s obligations to it under this Agreement until all such unsatisfied obligations are fully paid, and/or (ii) hold any such amounts in a segregated account as cash collateral for, and application to, any future funding
obligations of such Lender under this Agreement, in the case of each of clauses (i) and (ii) above, in any order as determined by the Administrative Agent in its discretion. 

(f)    Notwithstanding the foregoing, amounts received from any Loan Party that is not a Qualified ECP Loan Party shall
not be applied to any Excluded Swap Obligation of such Loan Party. 
 SECTION 2.18 Mitigation Obligations; Replacement of Lenders.

 (a)    If the Borrower is required to pay any Indemnified Taxes or additional amounts to any Lender or any
Governmental Authority for the account of any Lender pursuant to Section 2.16, then such Lender shall use reasonable efforts to designate a different lending office for funding or booking its Loans hereunder or to assign
its rights and obligations hereunder to another of its offices, branches or Affiliates, if, in the judgment of such Lender, such designation or assignment (i) would eliminate or reduce amounts payable pursuant to
Section 2.16 in the 

  
 44 

 
future and (ii) would not subject such Lender to any unreimbursed cost or expense and would not otherwise be disadvantageous to such Lender. The Borrower hereby agrees to pay all reasonable
costs and expenses incurred by any Lender in connection with any such designation or assignment. 
 (b)    If the
Borrower is required to pay any Indemnified Taxes or additional amounts to any Lender or any Governmental Authority for the account of any Lender pursuant to Section 2.16, or if any Lender becomes a Defaulting Lender, then
the Borrower may, at its sole expense and effort, upon notice to such Lender and the Administrative Agent, require such Lender to assign and delegate, without recourse (in accordance with and subject to the restrictions contained in
Section 9.04), all its interests, rights (other than its existing rights to payments pursuant to Section 2.16) and obligations under this Agreement to an assignee that shall assume such obligations
(which assignee may be another Lender, if a Lender accepts such assignment); provided that (i) the Borrower shall have received the prior written consent of the Administrative Agent (and, if a Revolving Commitment is being assigned, the Issuing
Bank), which consent shall not unreasonably be withheld, (ii) such assignor Lender shall have received payment of an amount equal to the outstanding principal of its Loans and participations in LC Disbursements, accrued interest thereon,
accrued fees and all other amounts payable to it hereunder, from the assignee (to the extent of such outstanding principal and accrued interest and fees) or the Borrower (in the case of all other amounts) and (iii) in the case of any such
assignment resulting from payments required to be made pursuant to Section 2.16, such assignment will result in a reduction in such compensation or payments. A Lender shall not be required to make any such assignment and
delegation if, prior thereto, as a result of a waiver by such Lender or otherwise, the circumstances entitling the Borrower to require such assignment and delegation cease to apply. 

SECTION 2.19 [Intentionally Left Blank]. 

SECTION 2.20 Defaulting Lender. Notwithstanding any provision of this Agreement to the contrary, if any Lender becomes a Defaulting
Lender, then the following provisions shall apply for so long as such Lender is a Defaulting Lender: 
 (a)    fees
shall cease to accrue on the unfunded portion of any Commitment of such Defaulting Lender pursuant to this Agreement; 

(b)    the Commitments and Revolving Exposure of such Defaulting Lender shall not be included in determining whether the
Required Lenders have taken or may take any action hereunder (including any consent to any amendment, waiver or other modification pursuant to Section 9.02); provided, that in the case of an amendment, waiver or other
modification requiring the consent of all Lenders or of each Lender affected thereby, the Defaulting Lender’s consent shall be only be required with respect to (i) a proposed increase or extension of such Defaulting Lender’s
Commitments and (ii) a proposed reduction or excuse, or a proposed postponement of the scheduled date of payment, of the principal amount of, or interest or fees payable on, any Loans or LC Disbursements as to any such Defaulting Lender; 

  
 45 

 (c)    if any LC Exposure exists at the time a Lender becomes a Defaulting
Lender then: 
 (i)    all or any part of the LC Exposure of such Defaulting Lender shall be reallocated
among the non-Defaulting Lenders in accordance with their respective Applicable Percentages but only (x) to the extent that such reallocation does not, as to any
non-Defaulting Lender, cause such non-Defaulting Lender’s Revolving Exposure to exceed its Commitment and (y) if the condition set forth in
Section 4.03 are satisfied at that time; 
 (ii)    if the reallocation
described in clause (i) above cannot, or can only partially, be effected, the Borrower shall within one (1) Business Day following notice by the Administrative Agent, cash collateralize for the benefit of the Issuing Bank only the
Borrower’s obligations corresponding to such Defaulting Lender’s LC Exposure (after giving effect to any partial reallocation pursuant to clause (i) above) in accordance with the procedures set forth in Section 2.04(j)
for so long as such LC Exposure is outstanding; 
 (iii)    if the Borrower cash collateralizes any
portion of such Defaulting Lender’s LC Exposure pursuant to this Section 2.20(c), the Borrower shall not be required to pay any fees to such Defaulting Lender pursuant to Section 2.11 with respect to such
Defaulting Lender’s LC Exposure during the period such Defaulting Lender’s LC Exposure is cash collateralized; 

(iv)    if the LC Exposure of the non-Defaulting Lenders is
reallocated pursuant to this Section 2.20(c), then the fees payable to the Lenders pursuant to Section 2.11 shall be adjusted in accordance with such non-Defaulting
Lenders’ Applicable Percentages; and 
 (v)    if all or any portion of such Defaulting
Lender’s LC Exposure is neither cash collateralized nor reallocated pursuant to this Section 2.20(c), then, without prejudice to any rights or remedies of the Issuing Bank or any Lender hereunder, all fees that otherwise would have been
payable to such Defaulting Lender (solely with respect to the portion of such Defaulting Lender’s Commitments that were utilized by such LC Exposure and any applicable letter of credit fees) with respect to such Defaulting Lender’s LC
Exposure shall be payable to the Issuing Bank until and to the extent that such LC Exposure is cash collateralized and/or reallocated; and 

(d)    so long as any Lender is a Defaulting Lender, the Issuing Bank shall not be required to issue, amend or increase
any Letter of Credit, unless it is satisfied that the related exposure and each Defaulting Lender’s then outstanding LC Exposure will be 100% covered by the Revolving Commitments of the non-Defaulting
Lenders and/or cash collateral will be provided by the Borrower in accordance with Section 2.20(c), and LC Exposure related to any newly issued or increased Letter of Credit shall be allocated among
non-Defaulting Lenders in a manner consistent with Section 2.20(c)(i) (and Defaulting Lenders shall not participate therein). 

  
 46 

 If (i) a Bankruptcy Event with respect to any Lender Parent shall occur following the date hereof and for so
long as such event shall continue or (ii) the Issuing Bank has a good faith belief that any Lender has defaulted in fulfilling its obligations under one or more other agreements in which such Lender commits to extend credit, the Issuing Bank
shall not be required to issue, amend or increase any Letter of Credit, unless the Issuing Bank shall have entered into arrangements with the Borrower or such Lender, satisfactory to the Issuing Bank to defease any risk to it in respect of such
Lender hereunder. 
 In the event that the Administrative Agent, the Borrower and the Issuing Bank each agrees that a Defaulting Lender has adequately
remedied all matters that caused such Lender to be a Defaulting Lender, then the LC Exposure of the Lenders shall be readjusted to reflect the inclusion of such Lender’s Revolving Commitment and on such date such Lender shall purchase at par
such of the Loans of the other Lenders as the Administrative Agent shall determine may be necessary in order for such Lender to hold such Loans in accordance with its Applicable Percentage. 

ARTICLE III 

Representations and Warranties

powers and have been duly authorized by all necessary corporate or limited liability company action. This Agreement has been duly executed and delivered by the Borrower and constitutes, and each other Loan Document to which any Loan Party is to be a
party, when executed and delivered by such Loan Party, will constitute, a legal, valid and binding obligation of the Borrower or such Loan Party (as the case may be), enforceable in accordance with its terms, subject to applicable bankruptcy,
insolvency, reorganization, moratorium or other laws affecting creditors’ rights generally and subject to general principles of equity, regardless of whether considered in a proceeding in equity or at law. 

SECTION 3.03 Governmental Approvals; No Conflicts. The Transactions (a) do not require any material consent or approval of,
registration or filing with, or any other action by, any Governmental Authority, except such as have been obtained or made and are in full force and effect and except filings necessary to perfect Liens created under the Loan Documents, (b) will
not violate any applicable law or regulation or the charter, by-laws or other organizational documents of the Borrower or any other applicable Loan Party or any order of any Governmental

  
 47 

 
Authority in each case, as are applicable to the Borrower and the Loan Parties, (c) will not violate or result in a default under any material indenture, agreement or other instrument
binding upon the Borrower or any other Loan Party or their assets, or give rise to a right thereunder to require any payment to be made by the Borrower or any other Loan Party, and (d) will not result in the creation or imposition of any Lien
on any asset of the Borrower or any other Loan Party, except Liens created under the Loan Documents. 
 SECTION 3.04 Financial
Condition. The Borrower has heretofore furnished to the Lenders Borrower’s consolidated balance sheet and statements of income, equity and cash flows (1) as of and for the fiscal year ended December 31, 2015 (subject to the

the fiscal year ended March 31, 2016, June 30, 2016 and September 30, 2016, certified by its chief financial officer. Such financial statements present fairly, in all material respects, the financial position and results of operations
and cash flows of the Borrower and its consolidated Subsidiaries as of such dates and for such periods in accordance with GAAP, subject to year-end audit adjustments and the absence of footnotes in the case of
the statements referred to in clause (2) above. Since December 31, 2015, there has been no material adverse change in the business, assets, operations, prospects or condition, financial or otherwise, of the Borrower and its
Subsidiaries, taken as a whole. Except as set forth on Schedule 6.01, after giving effect to the Transactions, none of the Borrower or its Subsidiaries has, as of the Effective Date, any material contingent liabilities or unrealized losses.

 SECTION 3.05 Properties. 

(a)    The Borrower and each other Loan Party has good title to, or valid leasehold interests in, all of its real and
personal property material to its business (including the Mortgaged Properties), except for minor defects in title that do not interfere with its ability to conduct its business as currently conducted or to utilize such properties for their intended
purposes. 
 (b)    The Borrower and each other Loan Party owns, or is licensed to use, all trademarks, trade names,
copyrights, patents and other intellectual property material to its business, and the use thereof by the Borrower and each other Loan Party does not infringe upon the rights of any other Person, except for any such infringements that could not
reasonably be expected to result in a Material Adverse Effect. 
 SECTION 3.06 Litigation and Environmental Matters. 

(a)    There are no actions, suits or proceedings by or before any arbitrator or Governmental Authority pending against or,
to the knowledge of the Borrower, threatened against or directly affecting the Borrower or any other Loan Party (i) as to which there is a reasonable possibility of an adverse determination and that, if adversely determined, could reasonably be
expected to result in a Material Adverse Effect or (ii) that directly involve any of the Loan Documents or the Transactions. 

  
 48 

 (b)    Except with respect to any other matters that could not reasonably be
expected to result in a Material Adverse Effect, neither the Borrower nor any other Loan Party (i) has failed to comply with any Environmental Law or to obtain, maintain or comply with any permit, license or other approval required under any
Environmental Law, (ii) has become subject to any Environmental Liability, (iii) has received notice of any claim with respect to any Environmental Liability or (iv) knows of any basis for any Environmental Liability. 

SECTION 3.07 Compliance with Laws and Agreements. The Borrower and each other Loan Party is in compliance with all laws, regulations
and orders of any Governmental Authority applicable to it or its property and all indentures, agreements and other instruments binding upon it or its property, except where the failure to do so could not reasonably be expected to result in a
Material Adverse Effect. No Default has occurred and is continuing. Without limiting the foregoing, Borrower represents and warrants that each Loan Party is in compliance with all applicable Bank Secrecy Act and anti-money laundering laws and
regulations and is in compliance, in all material respects, with the Patriot Act. 
 SECTION 3.08 Investment Company Status. Neither
the Borrower nor any other Loan Party is an “investment company” as defined in, or subject to regulation under, the Investment Company Act of 1940. 

SECTION 3.09 Taxes. The Borrower and each other Loan Party has timely filed or caused to be filed all Tax returns and reports required
to have been filed and has paid or caused to be paid all Taxes required to have been paid by it, except (a) Taxes that are being contested in good faith by appropriate proceedings and for which the Borrower or such other Loan Party, as
applicable, has set aside on its books adequate reserves or (b) to the extent that the failure to do so could not reasonably be expected to result in a Material Adverse Effect. 

SECTION 3.10 ERISA. No ERISA Event has occurred or is reasonably expected to occur that, when taken together with all other such ERISA
Events for which liability is reasonably expected to occur, could reasonably be expected to result in a Material Adverse Effect. To the extent applicable, the present value of all accumulated benefit obligations under each Plan (based on the
assumptions used for purposes of Statement of Financial Accounting Standards No. 87) did not, as of the date of the most recent financial statements reflecting such amounts, exceed the fair market value of the assets of such Plan, and the
present value of all accumulated benefit obligations of all underfunded Plans (based on the assumptions used for purposes of Statement of Financial Accounting Standards No. 87) did not, as of the date of the most recent financial statements
reflecting such amounts, exceed the fair market value of the assets of all such underfunded Plans, in each of such cases so as to cause a Material Adverse Effect. 

SECTION 3.11 Disclosure. The Borrower has disclosed to the Lenders all agreements, instruments and corporate or other restrictions to
which the Borrower or any other Loan Party is subject, and all other matters known to any of them, that could, in each case, reasonably be expected to result in a Material Adverse Effect. None of the reports, financial statements,

  
 49 

 
certificates or other information furnished by or on behalf of any Loan Party to the Administrative Agent or any Lender in connection with the negotiation of this Agreement or any other Loan
Document or delivered hereunder or thereunder (as modified or supplemented by other information so furnished) contains any material misstatement of fact or omits to state any material fact necessary to make the statements therein, taken as a whole,
in the light of the circumstances under which they were made, not misleading; provided, however, that with respect to projected financial information, the Borrower represents only that such information was prepared in good faith based upon
assumptions believed to be reasonable at the time. 
 SECTION 3.12 Subsidiaries. As of the Effective Date, the Borrower has no
Subsidiaries other than as set forth on Schedule 3.12 hereto. The Borrower owns all of the Equity Interests in and to each Subsidiary listed on Schedule 3.12 hereto. 

SECTION 3.13 Insurance. As of the Effective Date, all premiums due in respect of all insurance maintained by the Borrower and each
other Loan Party have been paid. 
 SECTION 3.14 Labor Matters. As of the Effective Date, there are no strikes, lockouts or slowdowns
against the Borrower or any other Loan Party pending or, to the knowledge of the Borrower, threatened. The hours worked by and payments made to employees of the Borrower and the other Loan Parties have not been in violation of the Fair Labor
Standards Act or any other applicable Federal, state, local or foreign law dealing with such matters. All payments due from the Borrower or any other Loan Party, or for which any claim may be made against the Borrower or any other Loan Party, on
account of wages and employee health and welfare insurance and other benefits, have been paid or accrued as a liability on the books of the Borrower or such other Loan Party. The consummation of the Transactions will not give rise to any right of
termination or right of renegotiation on the part of any union under any collective bargaining agreement to which the Borrower or any other Loan Party is bound. 

SECTION 3.15 Solvency. Immediately after the consummation of the Transactions to occur on the Effective Date and immediately following
the making of each Loan and after giving effect to the application of the proceeds of such Loans, (a) the fair value of the assets of each Loan Party, at a fair valuation, will exceed its debts and liabilities, subordinated, contingent or
otherwise; (b) the present fair saleable value of the property of each Loan Party will be greater than the amount that will be required to pay the probable liability of its debts and other liabilities, subordinated, contingent or otherwise, as
such debts and other liabilities become absolute and matured; (c) each Loan Party will be able to pay its debts and liabilities, subordinated, contingent or otherwise, as such debts and liabilities become absolute and matured; and (d) each
Loan Party will not have unreasonably small capital with which to conduct the business in which it is engaged as such business is now conducted and is proposed to be conducted following the Effective Date. 

SECTION 3.16 Material Property Subject to Security Documents. The Collateral constitutes all of the real and material personal property
owned by Borrower or any of its Subsidiaries (other than Excluded Assets). 

  
 50 

 SECTION 3.17 Property of Foreign Subsidiaries. The aggregate value (based on the greater
of book or market value) of the total assets owned by Foreign Subsidiaries of Borrower as of the Effective Date is no greater than 5% of the aggregate value (based on the greater of book or market value) of the total assets owned by Borrower and all
of its Subsidiaries. 
 SECTION 3.18 Anti-Corruption Laws and Sanctions. Each Loan Party has implemented and maintains in effect
policies and procedures designed to ensure compliance by each Loan Party and their respective directors, officers, employees and agents with Anti-Corruption Laws and applicable Sanctions, and each Loan Party and their respective officers and
directors and, to the knowledge of the Borrower, any of their respective employees and agents, are in compliance with Anti-Corruption Laws and applicable Sanctions in all material respects. None of (a) any Loan Party or any of their respective
directors, officers or employees, or (b) to the knowledge of the Borrower, any agent of any Loan Party that will act in any capacity in connection with or benefit from the credit facility established hereby, is a Sanctioned Person. No Borrowing
or Letter of Credit, use of proceeds or Transaction will violate Anti-Corruption Laws or applicable Sanctions.

ARTICLE VIII 
 The
Administrative Agent 
 Each of the Lenders and the Issuing Bank hereby irrevocably appoints the Administrative Agent as its agent and
authorizes the Administrative Agent to take such actions on its behalf and to exercise such powers as are delegated to the Administrative Agent by the terms of the Loan Documents, together with such actions and powers as are reasonably incidental
thereto. 
 The bank serving as the Administrative Agent hereunder shall have the same rights and powers in its capacity as a Lender as any
other Lender and may exercise the same as though it were not the Administrative Agent, and such bank and its Affiliates may accept deposits from, lend money to and generally engage in any kind of business with the Borrower or any of its Subsidiaries
or other Affiliate thereof as if it were not the Administrative Agent hereunder. 
 The Administrative Agent shall not have any duties or
obligations except those expressly set forth in the Loan Documents. Without limiting the generality of the foregoing, (a) the Administrative Agent shall not be subject to any fiduciary or other implied duties, regardless of whether a Default
has occurred and is continuing, (b) the Administrative Agent shall not have any duty to take any discretionary action or exercise any discretionary powers, except 

  
 68 

 
discretionary rights and powers expressly contemplated by the Loan Documents that the Administrative Agent is required to exercise in writing by the Required Lenders (or such other number or
percentage of the Lenders as shall be necessary under the circumstances as provided in Section 9.02), and (c) except as expressly set forth in the Loan Documents, the Administrative Agent shall not have any duty to
disclose, and shall not be liable for the failure to disclose, any information relating to the Borrower or any of its Subsidiaries that is communicated to or obtained by the bank serving as Administrative Agent or any of its Affiliates in any
capacity. The Administrative Agent shall not be liable for any action taken or not taken by it with the consent or at the request of the Required Lenders (or such other number or percentage of the Lenders as shall be necessary under the
circumstances as provided in Section 9.02) or in the absence of its own gross negligence or willful misconduct, BUT REGARDLESS OF THE PRESENCE OF ORDINARY NEGLIGENCE. The Administrative Agent shall not be deemed to have
knowledge of any Default unless and until written notice thereof is given to the Administrative Agent by the Borrower or a Lender, and the Administrative Agent shall not be responsible for or have any duty to ascertain or inquire into (i) any
statement, warranty or representation made in or in connection with any Loan Document, (ii) the contents of any certificate, report or other document delivered thereunder or in connection therewith, (iii) the performance or observance of
any of the covenants, agreements or other terms or conditions set forth in any Loan Document, (iv) the validity, enforceability, effectiveness or genuineness of any Loan Document or any other agreement, instrument or document, or (v) the
satisfaction of any condition set forth in Article IV or elsewhere in any Loan Document, other than to confirm receipt of items expressly required to be delivered to the Administrative Agent. 

The Administrative Agent shall be entitled to rely upon, and shall not incur any liability for relying upon, any notice, request, certificate,
consent, statement, instrument, document or other writing believed by it to be genuine and to have been signed or sent by the proper Person. The Administrative Agent also may rely upon any statement made to it orally or by telephone and believed by
it to be made by the proper Person, and shall not incur any liability for relying thereon. The Administrative Agent may consult with legal counsel (who may be counsel for the Borrower), independent accountants and other experts selected by it, and
shall not be liable for any action taken or not taken by it in accordance with the advice of any such counsel, accountants or experts. 

The Administrative Agent may perform any and all its duties and exercise its rights and powers by or through any one or more sub-agents appointed by the Administrative Agent. The Administrative Agent and any such sub-agent may perform any and all its duties and exercise its rights and powers through
their respective Related Parties. The exculpatory provisions of the preceding paragraphs shall apply to any such sub-agent and to the Related Parties of the Administrative Agent and any such sub-agent, and shall apply to their respective activities in connection with the syndication of the credit facilities provided for herein as well as activities as Administrative Agent. 

Subject to the appointment and acceptance of a successor Administrative Agent as provided in this paragraph, the Administrative Agent may
(and, in the event (i) neither the 

  
 69 

 
Administrative Agent nor any Affiliate of the Administrative Agent, as a Lender, has any Revolving Exposure, outstanding Advance Loan or unused Commitment and (ii) the Required Lenders so
request, the Administrative Agent shall) resign at any time by notifying the Lenders, the Issuing Bank and the Borrower. Upon any such resignation, the Required Lenders shall have the right, in consultation with the Borrower, to appoint a successor.
If no successor shall have been so appointed by the Required Lenders and shall have accepted such appointment within 30 days after the retiring Administrative Agent gives notice of its resignation, then the retiring Administrative Agent may, on
behalf of the Lenders and the Issuing Bank, appoint a successor Administrative Agent which shall be a bank with an office in Houston, Texas, or an Affiliate of any such bank. Upon the acceptance of its appointment as Administrative Agent hereunder
by a successor, such successor shall succeed to and become vested with all the rights, powers, privileges and duties of the retiring Administrative Agent, and the retiring Administrative Agent shall be discharged from its duties and obligations
hereunder. The fees payable by the Borrower to a successor Administrative Agent shall be the same as those payable to its predecessor unless otherwise agreed between the Borrower and such successor. After the Administrative Agent’s resignation
hereunder, the provisions of this Article and Section 9.03 shall continue in effect for the benefit of such retiring Administrative Agent, its sub agents and their respective Related Parties in respect of any actions taken
or omitted to be taken by any of them while it was acting as Administrative Agent. 
 Each Lender acknowledges and agrees that the
extensions of credit made hereunder are commercial loans and letters of credit and not investments in a business enterprise or securities. Each Lender further represents that it is engaged in making, acquiring or holding commercial loans in the
ordinary course of its business and has, independently and without reliance upon the Administrative Agent or any other Lender and based on such documents and information as it has deemed appropriate, made its own credit analysis and decision to
enter into this Agreement as a Lender, and to make, acquire or hold Loans hereunder. Each Lender shall, independently and without reliance upon the Administrative Agent or any other Lender and based on such documents and information (which may
contain material, non-public information within the meaning of the United States securities laws concerning the Borrower and its Affiliates) as it shall from time to time deem appropriate, continue to make its
own decisions in taking or not taking action under or based upon this Agreement, any related agreement or any document furnished hereunder or thereunder and in deciding whether or to the extent to which it will continue as a Lender or assign or
otherwise transfer its rights, interests and obligations hereunder.

the recipient). Notices delivered through Electronic Systems, to the extent provided in paragraph (b) below, shall be effective as provided in said paragraph (b). 

(b)    Notices and other communications to the Lenders and the Issuing Bank hereunder may be delivered or furnished using
Electronic Systems pursuant to procedures approved by the Administrative Agent; provided that the foregoing shall not apply to notices pursuant to Article II unless otherwise agreed by the Administrative Agent and the applicable Lender. The
Administrative Agent or the Borrower may, in its discretion, agree to accept notices and other communications to it hereunder by electronic communications pursuant to procedures approved by it; provided that approval of such procedures may be
limited to particular notices or communications. Unless the Administrative Agent otherwise prescribes, (i) notices and other communications sent to an e-mail address shall be deemed received upon the
sender’s receipt of an acknowledgement from the intended recipient (such as by the “return receipt requested” function, as available, return e-mail or other written acknowledgement), and
(ii) notices or communications posted to an Internet or intranet website shall be deemed received upon the deemed receipt by the intended recipient, at its e-mail address as described in the foregoing

(c)    Any party hereto may change its address or telecopy number for notices and other communications hereunder by notice

 71

not be obligated to, make Communications (as defined below) available to the Issuing Bank and the other Lenders by posting the Communications on Debt Domain, IntraLinks, Syndtrak, ClearPar or a substantially similar Electronic System. Any Electronic
System used by the Administrative Agent is provided “as is” and “as available.” The Agent Parties (as defined below) do not warrant the adequacy of such Electronic Systems and expressly disclaim liability for errors or omissions
in the Communications. No warranty of any kind, express, implied or statutory, including any warranty of merchantability, fitness for a particular purpose, non-infringement of third-party rights or freedom
from viruses or other code defects, is made by any Agent Party in connection with the Communications or any Electronic System. In no event shall the Administrative Agent or any of its Related Parties (collectively, the “Agent
Parties”) have any liability to the Borrower or any other Loan Party, any Lender, the Issuing Bank or any other Person or entity for damages of any kind, including direct or indirect, special, incidental or consequential damages, losses or
expenses (whether in tort, contract or otherwise) arising out of the Borrower’s, any Loan Party’s or the Administrative Agent’s transmission of communications through an Electronic System. “Communications” means,
collectively, any notice, demand, communication, information, document or other material provided by or on behalf of any Loan Party pursuant to any Loan Document or the transactions contemplated therein which is distributed by the Administrative
Agent, any Lender or any Issuing Bank by means of electronic communications pursuant to this Section, including through an Electronic System. 

SECTION 9.02 Waivers; Amendments. 

(a)    No failure or delay by the Administrative Agent, the Issuing Bank or any Lender in exercising any right or power
hereunder or under any other Loan Document shall operate as a waiver thereof, nor shall any single or partial exercise of any such right or power, or any abandonment or discontinuance of steps to enforce such a right or power, preclude any other or
further exercise thereof or the exercise of any other right or power. The rights and remedies of the Administrative Agent, the Issuing Bank and the Lenders hereunder and under the other Loan Documents are cumulative and are not exclusive of any
rights or remedies that they would otherwise have. No waiver of any provision of any Loan Document or consent to any departure by any Loan Party therefrom shall in any event be effective unless the same shall be permitted by Section 9.02(b),
and then such waiver or consent shall be effective only in the specific instance and for the purpose for which given. Without limiting the generality of the foregoing, the making of a Loan or issuance of a Letter of Credit shall not be construed as
a waiver of any Default, regardless of whether the Administrative Agent, any Lender or the Issuing Bank may have had notice or knowledge of such Default at the time. 

(b)    Subject to Section 9.02(c) below, neither this Agreement nor any other Loan Document nor any provision
hereof or thereof may be waived, amended or modified except, in the case of this Agreement, pursuant to an agreement or agreements in writing entered into by the Borrower and the Required Lenders or, in the case of any other Loan Document, pursuant
to an agreement or agreements in writing entered into by the Administrative Agent and the Loan Party or Loan Parties that are parties thereto, in each case with the consent of the Required 

  
 72 

 
Lenders; provided that no such agreement shall (i) increase the Commitment of any Lender without the written consent of such Lender, (ii) reduce the principal amount of any Loan or LC
Disbursement or reduce the rate of interest thereon, or reduce any fees payable hereunder, without the written consent of each Lender affected thereby, (iii) postpone the scheduled date of payment (including any mandatory prepayment) of the
principal amount of any Loan or LC Disbursement, or any interest thereon, or any fees payable hereunder, or reduce the amount of, waive or excuse any such payment, or postpone the scheduled date of expiration of any Commitment, without the written
consent of each Lender affected thereby, (iv) change Section 2.17(b) or (c) in a manner that would alter the pro rata sharing of payments required thereby, without the written consent of each Lender, (v) change any of
the provisions of this Section or the definition of “Required Lenders” or any other provision of any Loan Document specifying the number or percentage of Lenders (or Lenders of any Class) required to waive, amend or modify any rights
thereunder or make any determination or grant any consent thereunder, without the written consent of each Lender (or each Lender of such Class, as the case may be), (vi) release all or substantially all of the Guarantors from liability under the
Guaranty or limit the liability of all or substantially all of the Guarantors in respect of the Guaranty, without the written consent of each Lender, (vii) release all or substantially all of the Collateral from the Liens of the Security
Documents, without the written consent of each Lender or (vii) change any provisions of any Loan Document in a manner that by its terms adversely affects the rights in respect of payments due to Lenders holding Loans of any
Class differently than those holding Loans of any other Class, without the written consent of Lenders holding a majority in interest of the outstanding Loans and unused Commitments of each affected Class; provided further that (A) any
change to Section 2.20 shall require the written consent of each of the Administrative Agent and the Issuing Bank, (B) no agreement shall amend, modify or otherwise affect any of the rights or duties of the
Administrative Agent or the Issuing Bank without the prior written consent of the Administrative Agent or the Issuing Bank, as the case may be, (C) no such agreement shall amend or modify the provisions of Section 2.05
or any letter of credit application and any bilateral agreement between the Borrower and the Issuing Bank regarding the respective rights and obligations between the Borrower and the Issuing Bank in connection with the issuance of Letters of Credit
without the prior written consent of the Administrative Agent and the Issuing Bank, respectively, and (D) any waiver, amendment or modification of this Agreement that by its terms affects the rights or duties under this Agreement of the
Revolving Lenders (but not the Advance Loan Lenders) or the Advance Loan Lenders (but not the Revolving Lenders) may be effected by an agreement or agreements in writing entered into by the Borrower and requisite percentage in interest of the
affected Class of Lenders. 
 (c)    If the Administrative Agent and the Borrower acting together identify any
ambiguity, omission, mistake, typographical error or other defect in any provision of this Agreement or any other Loan Document, then the Administrative Agent and the Borrower shall be permitted to amend, modify or supplement such provision to cure
such ambiguity, omission, mistake, typographical error or other defect, and such amendment shall become effective without any further action or consent of any other party to this Agreement. 

  
 73 

 SECTION 9.03 Expenses; Indemnity; Damage Waiver. 

(a)    The Borrower shall pay (i) all reasonable out of pocket expenses incurred by the Administrative Agent and its
Affiliates, including the reasonable fees, charges and disbursements of counsel for the Administrative Agent, in connection with the syndication of the credit facilities provided for herein, the preparation and administration of the Loan Documents
or any amendments, modifications or waivers of the provisions thereof (whether or not the transactions contemplated hereby or thereby shall be consummated), (ii) all reasonable out of-pocket expenses incurred
by the Issuing Bank in connection with the issuance, amendment, renewal or extension of any Letter of Credit or any demand for payment thereunder and (iii) all
out-of-pocket expenses incurred by the Administrative Agent, the Issuing Bank or any Lender, including the fees, charges and disbursements of any counsel for the
Administrative Agent, the Issuing Bank or any Lender, in connection with the enforcement or protection of its rights in connection with the Loan Documents, including its rights under this Section, or in connection with the Loans made or Letters of
Credit issued hereunder, including all such out-of pocket expenses incurred during any workout, restructuring or negotiations in respect of such Loans or Letters of Credit. 

(b)    The Borrower shall indemnify the Administrative Agent, the Issuing Bank and each Lender, and each Related Party of
any of the foregoing Persons (each such Person being called an “Indemnitee”) against, and hold each Indemnitee harmless from, any and all losses, claims, damages, liabilities and related expenses, including the fees, charges and
disbursements of any counsel for any Indemnitee, incurred by or asserted against any Indemnitee arising out of, in connection with, or as a result of (i) the execution or delivery of any Loan Document or any other agreement or instrument
contemplated hereby or thereby, the performance by the parties to the Loan Documents of their respective obligations hereunder or thereunder or the consummation of the Transactions or any other transactions contemplated hereby, (ii) any Loan or
Letter of Credit or the use of the proceeds therefrom (including any refusal by the Issuing Bank to honor a demand for payment under a Letter of Credit if the documents presented in connection with such demand do not strictly comply with the terms
of such Letter of Credit), (iii) any actual or alleged presence or release of Hazardous Materials on or from any Mortgaged Property or any other property currently or formerly owned or operated by the Borrower or any of its Subsidiaries, or any
Environmental Liability related in any way to the Borrower or any of its Subsidiaries, or (iv) any actual or prospective claim, litigation, investigation or proceeding relating to any of the foregoing, whether or not such claim, litigation,
investigation or proceeding is brought by any Loan Party, or equity holders, affiliates or creditors or any Loan Party or any other third Person and whether based on contract, tort or any other theory and regardless of whether any Indemnitee is a
party thereto; provided that such indemnity shall not, as to any Indemnitee, be available to the extent that such losses, claims, damages, liabilities or related expenses are determined by a court of competent jurisdiction by final and non-appealable judgment to have resulted from the gross negligence or willful misconduct of such Indemnitee, BUT THE PRESENCE OF ORDINARY NEGLIGENCE SHALL NOT AFFECT THE AVAILABILITY OF SUCH INDEMNITY. This
Section 9.03(b) shall not apply with respect to Taxes other than any Taxes that represent losses, claims or damages arising from any non-Tax claim. 

  
 74 

 (c)    To the extent that the Borrower fails to pay any amount required to be
paid by it to the Administrative Agent or the Issuing Bank under Sections 9.03(a) or 9.03(b), each Lender severally agrees to pay to the Administrative Agent or the Issuing Bank, as the case may be, such Lender’s pro rata share
(determined as of the time that the applicable unreimbursed expense or indemnity payment is sought) of such unpaid amount; provided that the unreimbursed expense or indemnified loss, claim, damage, liability or related expense, as the case may be,
was incurred by or asserted against the Administrative Agent or the Issuing Bank in its capacity as such. For purposes hereof, a Lender’s “pro rata share” shall be determined based upon (without duplication) its share of the sum of
the total Revolving Exposures, outstanding Advance Loans and unused Commitments at the time. 
 (d)    To the extent
permitted by applicable law, no party hereto shall assert, and each such party hereby waives, any claim against any other party hereto, on any theory of liability, for special, indirect, consequential or punitive damages (as opposed to direct or
actual damages) arising out of, in connection with, or as a result of, this Agreement, any other Loan Document or any agreement or instrument contemplated hereby or thereby, the Transactions, any Loan or Letter of Credit or the use of the proceeds
thereof; provided that, nothing in this clause (d) shall relieve the Borrower of any obligation it may have to indemnify an Indemnitee against special, indirect, consequential or punitive damages asserted against such Indemnitee by a
third party. 
 (e)    All amounts due under this Section shall be payable not later than three (3) Business Days
after written demand therefor.

(a)    The provisions of this Agreement shall be binding upon and inure to the benefit of the parties hereto and their
respective successors and assigns permitted hereby (including any Affiliate of the Issuing Bank that issues any Letter of Credit), except that (i) the Borrower may not assign or otherwise transfer any of its rights or obligations hereunder
without the prior written consent of each Lender (and any attempted assignment or transfer by the Borrower without such consent shall be null and void) and (ii) no Lender may assign or otherwise transfer its rights or obligations hereunder
except in accordance with this Section. Nothing in this Agreement, expressed or implied, shall be construed to confer upon any Person (other than the parties hereto, their respective successors and assigns permitted hereby (including any Affiliate
of the Issuing Bank that issues any Letter of Credit), Participants (to the extent provided in Section 9.04(c)) and, to the extent expressly contemplated hereby, the Related Parties of each of the Administrative Agent, the Issuing Bank and
the Lenders) any legal or equitable right, remedy or claim under or by reason of this Agreement. 

  
 75 

 (b)    (i)    Subject to the conditions set forth in
paragraph (b)(ii) below, any Lender may assign to one or more Persons (other than an Ineligible Institution) all or a portion of its rights and obligations under this Agreement (including all or a portion of its Commitment, participations in Letters
of Credit and the Loans at the time owing to it) with the prior written consent (such consent not to be unreasonably withheld) of: 

(A)    the Borrower, provided that no consent of the Borrower shall be required for an assignment to a
Lender, an Affiliate of a Lender, an Approved Fund or, if an Event of Default has occurred and is continuing, any other assignee, and provided further that the Borrower shall be deemed to have consented to any such assignment unless it shall object
thereto by written notice to the Administrative Agent within five (5) Business Days after having received notice thereof; and 

(B)    the Administrative Agent, provided that no consent of the Administrative Agent shall be required for
an assignment of (x) any Revolving Commitment to an assignee that is a Lender (other than a Defaulting Lender) with a Revolving Commitment immediately prior to giving effect to such assignment and (y) all or any portion of an Advance Loan
to a Lender, an Affiliate of a Lender or an Approved Fund; and 
 (C)    the Issuing Bank, provided that
no consent of the Issuing Bank shall be required for an assignment of all or any portion of an Advance Loan. 

(ii)    Assignments shall be subject to the following additional conditions: 

(A)    except in the case of an assignment to a Lender or an Affiliate of a Lender or an assignment of the
entire remaining amount of the assigning Lender’s Commitment or Loans of any Class, the amount of the Commitment or Loans of the assigning Lender subject to each such assignment (determined as of the date the Assignment and Assumption with
respect to such assignment is delivered to the Administrative Agent) shall not be less than $500,000 in respect of a Revolving Commitment or $1,000,000 in respect of an Advance Loan Commitment and Advance Loans (in the aggregate), and shall not
result in the assigning Lender holding a Revolving Commitment of less than $500,000 or $1,000,000 in respect of an Advance Loan Commitment and Advance Loans (in the aggregate), unless each of the Borrower and the Administrative Agent otherwise
consent, provided that no such consent of the Borrower shall be required if an Event of Default has occurred and is continuing; 

(B)    each partial assignment shall be made as an assignment of a proportionate part of all the assigning
Lender’s rights and obligations under this Agreement, provided that this clause shall not be construed to prohibit the assignment of a proportionate part of all the assigning Lender’s rights and obligations in respect of one Class of
Commitments or Loans; 

  
 76 

 (C)    the parties to each assignment shall execute and
deliver to the Administrative Agent an Assignment and Assumption, together with a processing and recordation fee of $3,500; and 

(D)    the assignee, if it shall not be a Lender, shall deliver to the Administrative Agent an
Administrative Questionnaire. 
 For the purposes of this Section, the term “Approved Fund” and “Ineligible Institution”
have the following meanings: 
 “Approved Fund” means any Person (other than a natural person) that is
engaged in making, purchasing, holding or investing in bank loans and similar extensions of credit in the ordinary course of its business and that is administered or managed by (a) a Lender, (b) an Affiliate of a Lender or (c) an
entity or an Affiliate of an entity that administers or manages a Lender. 
 “Ineligible Institution” means
(a) a natural person, (b) a Defaulting Lender or its Lender Parent, (c) a company, investment vehicle or trust for, or owned and operated for the primary benefit of, a natural person or relative(s) thereof, or (d) the Borrower or
any of its Affiliates; provided that such company, investment vehicle or trust shall not constitute an Ineligible Institution if it (x) has not been established for the primary purpose of acquiring any Loans or Commitments, (y) is managed
by a professional advisor, who is not such natural person or a relative thereof, having significant experience in the business of making or purchasing commercial loans, and (z) has assets greater than $25,000,000 and a significant part of its
activities consist of making or purchasing commercial loans and similar extensions of credit in the ordinary course of its business; provided that upon the occurrence of an Event of Default, any Person (other than a Lender) shall be an Ineligible
Institution if after giving effect any proposed assignment to such Person, such Person would hold more than 25% of the then outstanding Total Revolving Exposure or Commitments, as the case may be. 

(iii)    Subject to acceptance and recording thereof pursuant to Section 9.04(b)(iv), from and after
the effective date specified in each Assignment and Assumption the assignee thereunder shall be a party hereto and, to the extent of the interest assigned by such Assignment and Assumption, have the rights and obligations of a Lender under this
Agreement, and the assigning Lender thereunder shall, to the extent of the interest assigned by such Assignment and Assumption, be released from its obligations under this Agreement (and, in the case of an Assignment and Assumption covering all of
the assigning Lender’s rights and obligations under this Agreement, such Lender shall cease to be a party hereto but shall continue to be entitled to the benefits of Sections 2.16 and 9.03). Any assignment or transfer by a Lender
of rights or obligations under this Agreement that does not comply with this Section shall be treated for purposes of this Agreement as a sale by such Lender of a participation in such rights and obligations in accordance with Section
9.04(c). 

  
 77 

 (iv)     The Administrative Agent, acting for this purpose as
a non-fiduciary agent of the Borrower, shall maintain at one of its offices a copy of each Assignment and Assumption delivered to it and a register for the recordation of the names and addresses of the
Lenders, and the Commitment of, and principal amount (and stated interest) of the Loans and LC Disbursements owing to, each Lender pursuant to the terms hereof from time to time (the “Register”). The entries in the Register shall be
conclusive, and the Borrower, the Administrative Agent, the Issuing Bank and the Lenders shall treat each Person whose name is recorded in the Register pursuant to the terms hereof as a Lender hereunder for all purposes of this Agreement,
notwithstanding notice to the contrary. The Register shall be available for inspection by the Borrower, the Issuing Bank and any Lender, at any reasonable time and from time to time upon reasonable prior notice. 

(v)    Upon its receipt of a duly completed Assignment and Assumption executed by an assigning Lender and
an assignee, the assignee’s completed Administrative Questionnaire (unless the assignee shall already be a Lender hereunder), the processing and recordation fee referred to in Section 9.04(b) and any written consent to such assignment
required by Section 9.04(b), the Administrative Agent shall accept such Assignment and Assumption and record the information contained therein in the Register; provided that if either the assigning Lender or the assignee shall have failed to
make any payment required to be made by it pursuant to this Agreement, the Administrative Agent shall have no obligation to accept such Assignment and Assumption and record the information therein in the Register unless and until such payment shall
have been made in full, together with all accrued interest thereon. No assignment shall be effective for purposes of this Agreement unless it has been recorded in the Register as provided in this Section 9.04(b)(v). 

(c)     Any Lender may, without the consent of the Borrower, the Administrative Agent or the Issuing Bank, sell
participations to one or more banks or other entities (a “Participant”), other than an Ineligible Institution, in all or a portion of such Lender’s rights and obligations under this Agreement (including all or a portion of its
Commitment and the Loans owing to it); provided that (A) such Lender’s obligations under this Agreement shall remain unchanged; (B) such Lender shall remain solely responsible to the other parties hereto for the performance of such
obligations; and (C) the Borrower, the Administrative Agent, the Issuing Bank and the other Lenders shall continue to deal solely and directly with such Lender in connection with such Lender’s rights and obligations under this Agreement.
Any agreement or instrument pursuant to which a Lender sells such a participation shall provide that such Lender shall retain the sole right to enforce this Agreement and to approve any amendment, modification or waiver of any provision of this
Agreement; provided that such agreement or instrument may provide that such Lender will not, without the consent of the Participant, agree to any amendment, modification or waiver described in the first proviso to Section 9.02(b) that affects
such Participant. The Borrower agrees that each Participant shall be entitled to the benefits of Section 2.16 (subject to the requirements and limitations therein, including the requirements under Sections 2.16(f)
and (g) (it being understood that the documentation required under Section 2.16(f) shall be delivered to the participating Lender and the information and documentation required under Section 2.16(g)

  
 78 

 
will be delivered to the Borrower and the Administrative Agent)) to the same extent as if it were a Lender and had acquired its interest by assignment pursuant to Section 9.04(b); provided
that such Participant (A) agrees to be subject to the provisions of Section 2.18 as if it were an assignee under Section 9.04(b); and (B) shall not be entitled to receive any greater payment under
Section 2.16, with respect to any participation, than its participating Lender would have been entitled to receive, except to the extent such entitlement to receive a greater payment results from a Change in Law that occurs
after the Participant acquired the applicable participation. Each Lender that sells a participation agrees, at the Borrower’s request and expense, to use reasonable efforts to cooperate with the Borrower to effectuate the provisions of
Section 2.18(b) with respect to any Participant. To the extent permitted by law, each Participant also shall be entitled to the benefits of Section 9.08 as though it were a Lender, provided that such Participant
agrees to be subject to Section 2.17(c) as though it were a Lender. Each Lender that sells a participation shall, acting solely for this purpose as an agent of the Borrower, maintain a register on which it enters the name and address of each
Participant and the principal amounts (and stated interest) of each Participant’s interest in the Loans or other obligations under the Loan Documents (the “Participant Register”); provided that no Lender shall have any
obligation to disclose all or any portion of the Participant Register to any Person (including the identity of any Participant or any information relating to a Participant’s interest in any Commitments, Loans, Letters of Credit or its other
obligations under any Loan Document) to any Person except to the extent that such disclosure is necessary to establish that such Commitment, Loan, Letter of Credit or other obligation is in registered form under Section 5f.103-1(c) of the United States Treasury Regulations. The entries in the Participant Register shall be conclusive absent manifest error, and such Lender shall treat each Person whose name is recorded in the
Participant Register as the owner of such participation for all purposes of this Agreement notwithstanding any notice to the contrary. For the avoidance of doubt, the Administrative Agent (in its capacity as Administrative Agent) shall have no
responsibility for maintaining a Participant Register. 
 (d)    Any Lender may at any time pledge or assign a security
interest in all or any portion of its rights under this Agreement to secure obligations of such Lender to a Federal Reserve Bank, and this Section shall not apply to any such pledge or assignment of a security interest; provided that no such pledge
or assignment of a security interest shall release a Lender from any of its obligations hereunder or substitute any such pledgee or assignee for such Lender as a party hereto. 

SECTION 9.05 Survival. All covenants, agreements, representations and warranties made by the Loan Parties in the Loan Documents and in
the certificates or other instruments delivered in connection with or pursuant to this Agreement or any other Loan Document shall be considered to have been relied upon by the other parties hereto and shall survive the execution and delivery of the
Loan Documents and the making of any Loans and issuance of any Letters of Credit, regardless of any investigation made by any such other party or on its behalf and notwithstanding that the Administrative Agent, the Issuing Bank or any Lender may
have had notice or knowledge of any Default or incorrect representation or warranty at the time any credit is extended hereunder, and shall continue in full force and effect as long as the principal of or

  
 79 

 
any accrued interest on any Loan or any fee or any other amount payable under this Agreement is outstanding and unpaid or any Letter of Credit is outstanding and so long as the Commitments have
not expired or terminated. The provisions of Sections 2.16 and 9.03 and Article VIII shall survive and remain in full force and effect regardless of the consummation of the transactions contemplated hereby, the repayment of the
Loans, the expiration or termination of the Letters of Credit and the Commitments or the termination of this Agreement or any provision hereof. 

SECTION 9.06 Counterparts; Integration; Effectiveness; Electronic Execution. 

(a)    This Agreement may be executed in counterparts (and by different parties hereto on different counterparts), each of
which shall constitute an original, but all of which when taken together shall constitute a single contract. This Agreement, the other Loan Documents and any separate letter agreements with respect to (i) fees payable to the Administrative
Agent and (ii) the reductions of the Letter of Credit Commitment constitute the entire contract among the parties relating to the subject matter hereof and supersede any and all previous agreements and understandings, oral or written, relating
to the subject matter hereof. Except as provided in Section 4.01, this Agreement shall become effective when it shall have been executed by the Administrative Agent and when the Administrative Agent shall have received
counterparts hereof which, when taken together, bear the signatures of each of the other parties hereto, and thereafter shall be binding upon and inure to the benefit of the parties hereto and their respective successors and assigns. Delivery of an
executed counterpart of a signature page of this Agreement by telecopy shall be effective as delivery of a manually executed counterpart of this Agreement. 

(b)    Delivery of an executed counterpart of a signature page of this Agreement by telecopy, emailed pdf. or any other
electronic means that reproduces an image of the actual executed signature page shall be effective as delivery of a manually executed counterpart of this Agreement. The words “execution,” “signed,” “signature,”
“delivery,” and words of like import in or relating to any document to be signed in connection with this Agreement and the transactions contemplated hereby shall be deemed to include Electronic Signatures, deliveries or the keeping of
records in electronic form, each of which shall be of the same legal effect, validity or enforceability as a manually executed signature, physical delivery thereof or the use of a paper-based recordkeeping system, as the case may be, to the extent
and as provided for in any applicable law, including the Federal Electronic Signatures in Global and National Commerce Act or any similar state laws based on the Uniform Electronic Transactions Act; provided that nothing herein shall require the
Administrative Agent to accept electronic signatures in any form or format without its prior written consent. 
 SECTION 9.07
Severability. Any provision of this Agreement held to be invalid, illegal or unenforceable in any jurisdiction shall, as to such jurisdiction, be ineffective to the extent of such invalidity, illegality or unenforceability without affecting
the validity, legality and enforceability of the remaining provisions hereof; and the invalidity of a particular provision in a particular jurisdiction shall not invalidate such provision in any other jurisdiction. 

  
 80 

 SECTION 9.08 Right of Setoff. If an Event of Default shall have occurred and be
continuing, each Lender and each of its Affiliates is hereby authorized at any time and from time to time, to the fullest extent permitted by law, to set off and apply any and all deposits (general or special, time or demand, provisional or final)
at any time held and other obligations at any time owing by such Lender or Affiliate to or for the credit or the account of the Borrower against any of and all the obligations of the Borrower now or hereafter existing under this Agreement held by
such Lender, irrespective of whether or not such Lender shall have made any demand under this Agreement and although such obligations may be unmatured. The rights of each Lender under this Section are in addition to other rights and remedies
(including other rights of setoff) which such Lender may have. 
 SECTION 9.09 Governing Law; Jurisdiction; Consent to Service of
Process. 
 (a)    This Agreement shall be construed in accordance with and governed by the law of the State of
Texas. 
 (b)    The Borrower hereby irrevocably and unconditionally submits, for itself and its property, to the
exclusive jurisdiction of each court of the State of Texas sitting in Montgomery County and of the United States District Court for the Southern District of Texas (Houston Division), and any appellate court from any thereof, in any action or
proceeding arising out of or relating to any Loan Document, or for recognition or enforcement of any judgment, and each of the parties hereto hereby irrevocably and unconditionally agrees that all claims in respect of any such action or proceeding
may be heard and determined in such Texas State or, to the extent permitted by law, in such Federal court. Each of the parties hereto agrees that a final judgment in any such action or proceeding shall be conclusive and may be enforced in other
jurisdictions by suit on the judgment or in any other manner provided by law. Nothing in this Agreement or any other Loan Document shall affect any right that the Administrative Agent, the Issuing Bank or any Lender may otherwise have to bring any
action or proceeding relating to this Agreement or any other Loan Document against the Borrower or its properties in the courts of any jurisdiction. 

(c)    The Borrower hereby irrevocably and unconditionally waives, to the fullest extent it may legally and effectively do
so, any objection which it may now or hereafter have to the laying of venue of any suit, action or proceeding arising out of or relating to this Agreement or any other Loan Document in any court referred to in Section 9.09(b). Each of the
parties hereto hereby irrevocably waives, to the fullest extent permitted by law, the defense of an inconvenient forum to the maintenance of such action or proceeding in any such court. 

(d)    Each party to this Agreement irrevocably consents to service of process in the manner provided for notices in
Section 9.01. Nothing in this Agreement or any other Loan Document will affect the right of any party to this Agreement to serve process in any other manner permitted by law. 

  
 81 

 SECTION 9.10 WAIVER OF JURY TRIAL. BORROWER HEREBY AGREES NOT TO ELECT A TRIAL BY JURY OF
ANY ISSUE TRIABLE OF RIGHT BY JURY, AND WAIVES ANY RIGHT TO TRIAL BY JURY FULLY TO THE EXTENT THAT ANY SUCH RIGHT SHALL NOW OR HEREAFTER EXIST WITH REGARD TO THIS AGREEMENT OR ANY OTHER LOAN DOCUMENT, OR ANY CLAIM, COUNTERCLAIM OR OTHER ACTION
ARISING IN CONNECTION THEREWITH. THIS WAIVER OF RIGHT TO TRIAL BY JURY IS GIVEN KNOWINGLY AND VOLUNTARILY BY BORROWER, AND IS INTENDED TO ENCOMPASS INDIVIDUALLY EACH INSTANCE AND EACH ISSUE AS TO WHICH THE RIGHT TO A TRIAL BY JURY WOULD OTHERWISE
ACCRUE. EACH CREDIT PARTY IS HEREBY AUTHORIZED TO FILE A COPY OF THIS SECTION IN ANY PROCEEDING AS CONCLUSIVE EVIDENCE OF THIS WAIVER BY BORROWER. 

SECTION 9.11 Headings. Article and Section headings and the Table of Contents used herein are for convenience of reference only, are
not part of this Agreement and shall not affect the construction of, or be taken into consideration in interpreting, this Agreement. 

SECTION 9.12 Interest Rate Limitation. Borrower and the Lenders intend to strictly comply with all applicable federal and Texas laws,
including applicable usury laws (or the usury laws of any jurisdiction whose usury laws are deemed to apply to the Notes or any other Loan Documents despite the intention and desire of the parties to apply the usury laws of the State of Texas).
Accordingly, the provisions of this Section shall govern and control over every other provision of this Agreement or any other Loan Document which conflicts or is inconsistent with this Section, even if such provision declares that it controls. As
used in this Section, the term “interest” includes the aggregate of all charges, fees, benefits or other compensation which constitute interest under applicable law, provided that, to the maximum extent permitted by applicable law,
(a) any non-principal payment shall be characterized as an expense or as compensation for something other than the use, forbearance or detention of money and not as interest, and (b) all interest at
any time contracted for, reserved, charged or received shall be amortized, prorated, allocated and spread, using the actuarial method, during the full term of the Notes. In no event shall Borrower or any other Person be obligated to pay, or any
Lender have any right or privilege to reserve, receive or retain, (a) any interest in excess of the maximum amount of nonusurious interest permitted under the laws of the State of Texas or the applicable laws (if any) of the United States or of
any other jurisdiction, or (b) total interest in excess of the amount which such Lender could lawfully have contracted for, reserved, received, retained or charged had the interest been calculated for the full term of the Notes at the Ceiling
Rate. The daily interest rates to be used in calculating interest at the Ceiling Rate shall be determined by dividing the applicable Ceiling Rate per annum by the number of days in the calendar year for which such calculation is being made. None of
the terms and provisions contained in this Agreement or in any other Loan Document (including, without limitation, Article VII hereof) which directly or indirectly relate to interest shall ever be construed without reference to this Section,
or be construed to create a contract to pay for the use, forbearance or detention of money at any interest rate in excess of the Ceiling Rate. If the term of any Note is shortened by reason of acceleration or maturity as a result of any Default or
by any other cause, or by reason 

  
 82 

 
of any required or permitted prepayment, and if for that (or any other) reason any Lender at any time, including but not limited to, the stated maturity, is owed or receives (and/or has received)
interest in excess of interest calculated at the Ceiling Rate, then and in any such event all of any such excess interest shall be canceled automatically as of the date of such acceleration, prepayment or other event which produces the excess, and,
if such excess interest has been paid to such Lender, it shall be credited pro tanto against the then-outstanding principal balance of Borrower’s obligations to such Lender, effective as of the date or dates when the event occurs which causes
it to be excess interest, until such excess is exhausted or all of such principal has been fully paid and satisfied, whichever occurs first, and any remaining balance of such excess shall be promptly refunded to its payor. 

SECTION 9.13 Keepwell. Each Qualified ECP Loan Party hereby jointly and severally absolutely, unconditionally and irrevocably
undertakes to provide such funds or other support as may be needed from time to time by each other Loan Party to honor all of its obligations under any Loan Document in respect of Swap Obligations (provided, however, that each Qualified ECP Loan
Party shall only be liable under this Section for the maximum amount of such liability that can be hereby incurred without rendering its obligations under this Section or otherwise under any applicable Loan Document voidable under applicable law
relating to fraudulent conveyance or fraudulent transfer, and not for any greater amount). Each Qualified ECP Loan Party intends that this Section constitute, and this Section shall be deemed to constitute, a “keepwell, support, or other
agreement” for the benefit of each other Loan Party for all purposes of Section 1a(18)(A)(v)(II) of the Commodity Exchange Act. 

SECTION 9.14 Patriot Act. Each Lender that is subject to the requirements of the Patriot Act hereby notifies the Borrower that pursuant
to the requirements of the Patriot Act, it is required to obtain, verify and record information that identifies the Borrower, which information includes the name and address of the Borrower and other information that will allow such Lender to
identify the Borrower in accordance with the Patriot Act.
