regulation or any change in applicable law or regulation or in the interpretation or administration thereof by any governmental authority charged with the interpretation or administration thereof, or compliance by the Bank with any applicable
guideline or request from any central bank or governmental authority (whether or not having the force of law) (i) shall change the basis of taxation of payments to the Bank of the principal of or interest on any Advance made by the Bank or any
other fees or amounts payable hereunder, other than (x) taxes imposed on the overall net income or franchise taxes with respect to the Bank or its lending office by the jurisdiction in which the Bank or its lending office has its principal
office or by any political subdivision or taxing authority therein (or any tax which is enacted or adopted by such jurisdiction, political subdivision or taxing authority as a direct substitute for any such taxes) or (y) any tax, assessment or
other governmental charge that would not have been imposed but for the failure of the Bank to comply with any certification, information, documentation or other reporting requirement, or (ii) shall impose, modify or deem applicable any reserve,
special deposit or similar requirement against assets of, deposits with or for the account of, or credit extended by the Bank, and the result of any of the foregoing shall be to increase the cost to the Bank of maintaining its Commitment or to
reduce the amount of any sum received or receivable by the Bank hereunder (whether of principal, interest or otherwise) in respect thereof by an amount deemed in good faith by the Bank to be material, then the Borrower shall pay to the Bank such
additional amount as will compensate the Bank for such increase or reduction upon demand by the Bank. Notwithstanding the foregoing, in no event shall the Bank be permitted to receive any compensation hereunder constituting interest in excess of the
Highest Lawful Rate. 
  

 -21- 

 (c) If the Bank shall have determined in good faith that the adoption of any
applicable law, rule, regulation or guideline regarding capital adequacy, or any change therein, or any change in the interpretation or administration thereof by any governmental authority, central bank or comparable agency charged with the
interpretation or administration thereof, or compliance by the Bank (or any lending office of the Bank) with any request or directive regarding capital adequacy (whether or not having the force of law) of any such authority, central bank or
comparable agency (including any capital adequacy guidelines under consideration as of the date of this Agreement by the Board of Governors of the Federal Reserve System and the Comptroller of the Currency) (except any such adoption or change
reflected in the Adjusted LIBO Rate), has or would have the effect of reducing the rate of return on the Bank’s capital or any corporation controlling the Bank’s capital as a consequence of its obligations hereunder to a level below that
which the Bank could have achieved but for such adoption, change or compliance (taking into consideration the Bank’s policies with respect to capital adequacy) by an amount deemed by the Bank to be material, then from time to time the Borrower
shall pay to the Bank such additional amount or amounts as will compensate the Bank for such reduction upon demand by the Bank. Notwithstanding the foregoing, in no event shall the Bank be permitted to receive any compensation hereunder constituting
interest in excess of the Highest Lawful Rate. 
 (d) If the Bank seeks compensation under this Agreement it will
notify the Borrower of any event occurring after the date of this Agreement which will entitle the Bank to compensation pursuant to this Section, as promptly as practicable, and in any event within 180 days after it becomes aware thereof and
determines to request compensation. A certificate of the Bank setting forth in reasonable detail (i) such amount or amounts as shall be necessary to compensate the Bank as specified in paragraph (a) or (b) above, as the case may be,
and (ii) the calculation of such amount or amounts shall be delivered to the Borrower and shall be prima facie evidence of such amount or amounts. The Borrower shall pay to the Bank the amount shown as due on any such certificate within ten
days after its receipt of the same. 
 (e) Failure on the part of the Bank to demand compensation for any
increased costs or reduction in amounts received or receivable or reduction in return on capital with respect to any Advance shall not constitute a waiver of the Bank’s rights to demand compensation for any increased costs or reduction in
amounts received or receivable or reduction in return on capital with respect to such Advance, provided that Borrower’s obligation to pay the Bank shall be limited to the increased costs or reduced amount that is attributable to the period
commencing 180 days prior to the date on which the Bank gives the Borrower notice under subsection (d) hereof. The protection of this Section shall be available to the Bank regardless of any possible contention of invalidity or inapplicability
of law, regulation or condition that has been imposed. 
 SECTION 3.11 Indemnity. The Borrower shall indemnify the Bank
against any loss or reasonable expense which the Bank may sustain or incur as a consequence of (a) any failure by the Borrower to fulfill on the date of any Advance hereunder the applicable conditions set forth in Article V, (b) any
failure by the Borrower to borrow hereunder after a Request for Advance pursuant to Article II has been given, (c) any default in the payment or prepayment of the principal amount of any Advance or any part thereof or interest accrued
thereon, as and when due and payable (at the due date thereof, by notice of prepayment or otherwise) or (d) the

  

 -22- 

 
occurrence of any Event of Default. A certificate of the Bank setting forth any amount or amounts which the Bank is entitled to receive pursuant to this Section shall be delivered to the Borrower
and shall be conclusive, if made in good faith, absent demonstrable error. The Borrower shall pay to the Bank the amount shown as due on any certificate within 30 days after its receipt of the same. Notwithstanding the foregoing, in no event shall
the Bank be permitted to receive any compensation hereunder constituting interest in excess of the Highest Lawful Rate. Without prejudice to the survival of any other obligations of the Borrower hereunder, the obligations of the Borrower as to any
claim under this Section shall survive the termination of this Agreement, the payment or assignment of any of the Notes or any combination of the foregoing provided notice of such claim shall have been given to the Borrower within 180 days after
such termination or assignment. 
 ARTICLE IV 
 LETTERS OF CREDIT 
 SECTION 4.01 General. Subject to the terms and
conditions set forth herein, the Borrower may request the issuance of Letters of Credit for its own account, in a form reasonably acceptable to the Bank, at any time and from time to time prior to the Working Capital Loan Maturity Date. In the event
of any inconsistency between the terms and conditions of this Agreement and the terms and conditions of any form of letter of credit application or other agreement submitted by the Borrower to, or entered into by the Borrower with, the Bank relating
to any Letter of Credit, the terms and conditions of this Agreement shall control. On and after the Effective Date, each Existing Letter of Credit shall be a Letter of Credit issued hereunder. 
 SECTION 4.02 Notice of Issuance, Amendment, Renewal, Extension; Certain Conditions. To request the issuance of a Letter of Credit (or
the amendment, renewal or extension of an outstanding Letter of Credit), the Borrower shall hand deliver or telecopy (or transmit by electronic communication, if arrangements for doing so have been approved by the Bank) to the Bank (reasonably in
advance of the requested date of issuance, amendment, renewal or extension) a notice requesting the issuance of a Letter of Credit, or identifying the Letter of Credit to be amended, renewed or extended, and specifying the date of issuance,
amendment, renewal or extension (which shall be a Business Day), the date on which such Letter of Credit is to expire (which shall comply with Section 4.03), the amount (in Dollars) of such Letter of Credit, the name and address of the
beneficiary thereof and such other information as shall be necessary to prepare, amend, renew or extend such Letter of Credit. If requested by the Bank, the Borrower also shall submit a letter of credit application on the Bank’s standard form
in connection with any request for a Letter of Credit. A Letter of Credit shall be issued, amended, renewed or extended only if (and upon issuance, amendment, renewal or extension of each Letter of Credit, the Borrower shall be deemed to represent
and warrant that) after giving effect to such issuance, amendment, renewal or extension (i) the LC Exposure shall not exceed $1,000,000 and (ii) the total Working Capital Exposure shall not exceed the total Working Capital Loan Commitment.

 SECTION 4.03 Expiration Date. Each Letter of Credit shall expire at or prior to the close of business on the earlier
of (i) the date one year after the date of the issuance of such Letter of Credit (or, in the case of any renewal or extension thereof, one year after such renewal

  

 -23- 

 
or extension) and (ii) the date that is 30 Business Days prior to the Working Capital Loan Maturity Date; provided, however, that any Letter of Credit with a one-year tenor may
provide for the renewal thereof for additional one-year periods (which shall in no event extend beyond the date referred to in clause (ii) above). 
 SECTION 4.04 Reimbursement. If the Bank makes any LC Disbursement in respect of a Letter of Credit, the Borrower shall reimburse such LC Disbursement by paying to the Bank an amount equal to such
LC Disbursement not later than 12:00 noon, Houston, Texas time, on (i) the Business Day that the Borrower receives notice of such LC Disbursement, if such notice is received prior to 11:00 a.m., Houston, Texas time, on the day of receipt, or
(ii) the Business Day immediately following the day that the Borrower receives such notice, if such notice is not received prior to such time on the day of receipt; provided, however, that, if no Default has occurred and is
continuing, the Borrower may, subject to the conditions to borrowing set forth herein, request in accordance with Section 2.01(a) an Advance to finance such reimbursement and, to the extent so financed, the Borrower’s obligation to
make such payment shall be discharged and replaced by the resulting Working Capital Advance. 
 SECTION 4.05 Obligations
Absolute. The Borrower’s obligation to reimburse LC Disbursements as provided in Section 4.04 shall be absolute, unconditional and irrevocable, and shall be performed strictly in accordance with the terms of this Agreement under
any and all circumstances whatsoever and irrespective of (i) any lack of validity or enforceability of any Letter of Credit or this Agreement, or any term or provision therein, (ii) any draft or other document presented under a Letter of
Credit proving to be forged, fraudulent or invalid in any respect or any statement therein being untrue or inaccurate in any respect, (iii) payment by the 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 this Section, constitute a legal or equitable
discharge of, or provide a right of setoff against, the Borrower’s obligations hereunder. Neither the Bank nor any of its Affiliates 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
Bank; provided, however, that the foregoing shall not be construed to excuse the Bank from liability to the Borrower to the extent of any direct damages (as opposed to consequential damages, claims in respect of which are hereby waived
by the Borrower to the extent permitted by applicable law) suffered by the Borrower that are caused by the Bank’s failure to exercise care when determining whether drafts and other documents presented under a Letter of Credit comply with the
terms thereof. In the absence of gross negligence or willful misconduct on the part of the Bank (as finally determined by a court of competent jurisdiction), the Bank shall be deemed to have exercised care in each such determination. In furtherance
of the foregoing and without limiting the generality thereof, with respect to documents presented that appear on their face to be in substantial compliance with the terms of a Letter of Credit, the 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. 
  

 -24- 

 SECTION 4.06 Disbursement Procedures. The Bank shall, promptly following its receipt
thereof, examine all documents purporting to represent a demand for payment under a Letter of Credit. The Bank shall promptly notify the Borrower by telephone (confirmed by telecopy) of such demand for payment and whether the Bank has made or will
make an LC Disbursement thereunder; provided, however, that any failure to give or delay in giving such notice shall not relieve the Borrower of its obligation to reimburse the Bank with respect to any such LC Disbursement. 

SECTION 4.07 Interim Interest. If the Bank shall make any LC Disbursement, then, unless the Borrower shall reimburse such LC
Disbursement in full on the date such LC Disbursement is made, the unpaid amount thereof shall bear interest, for each day from and including the date such LC Disbursement is made to but excluding the date that the Borrower reimburses such LC
Disbursement, at the rate per annum then applicable to the Working Capital Loan; provided, however, that, if the Borrower fails to reimburse such LC Disbursement when due pursuant to Section 4.04, then
Section 3.03(c) shall apply. 
 SECTION 4.08 Cash Collateralization. If any Event of Default shall occur and
be continuing, on the Business Day that the Borrower receives notice from the Bank demanding the deposit of cash collateral pursuant to this paragraph, the Borrower shall deposit in an account with the Bank, in the name of the Bank, an amount in
cash equal to 105% of the LC Exposure as of such date plus any accrued and unpaid interest thereon; provided, however, that the obligation to deposit such cash collateral shall become effective immediately, and such deposit shall
become immediately due and payable, without demand or other notice of any kind, upon the occurrence of any Event of Default with respect to the Borrower described in clause (d) or (e) of Section 9.01. Such deposit shall be held
by the Bank as collateral for the payment and performance of the obligations of the Borrower under this Agreement. The Bank 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 Bank 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. The Bank shall apply moneys in such account to reimburse itself 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, be applied to satisfy other obligations of the Borrower under this Agreement. If the Borrower is required to provide an
amount of cash collateral hereunder as a result of the occurrence of an Event of Default, such amount (to the extent not applied as aforesaid) shall be returned to the Borrower within three Business Days after all Events of Default have been cured
or waived.

the PBGC for premiums under Section 4007 of ERISA). No litigation, investigation or claim (other than a routine claim for benefits) is pending or, to the knowledge of the Borrower, threatened or anticipated concerning any Plan and no unfunded
liability (whether or not current or contingent) exists under or with respect to any Plan. 
 SECTION 6.14 Acceptable
Security Interest. The Security Agreement is effective to create in favor of the Bank a valid Lien on all right, title and interest of each Credit Party, as applicable, in the Collateral, as security for the Obligations, prior and superior in

 SECTION 10.06 Interest. Anything in this agreement or the other Loan Documents to the contrary notwithstanding, the Borrower shall never be required to pay unearned interest on any Note and shall
never be required to pay interest on such Note at a rate in excess of the Highest Lawful Rate, and if the effective rate of interest that would otherwise be payable under this Agreement, the other Loan Documents and such Note would exceed the
Highest Lawful Rate, or if the holder of such Note shall receive any unearned interest or shall receive monies that are deemed to constitute interest that would increase the effective rate of interest payable by the Borrower under this Agreement and

highest nonusurious amount allowed under applicable law; and (b) any unearned interest paid by the Borrower or any interest paid by the Borrower in excess of the Highest Lawful Rate shall be credited on the principal of such Note and, to the

determining whether such rate exceeds the Highest Lawful Rate applicable to the Bank (such Highest Lawful Rate being the Bank’s “Maximum Permissible Rate”) and shall be made, to the extent permitted by usury laws applicable to
the Bank (now or hereafter enacted), by amortizing, prorating and spreading in equal parts during the period of the full stated term of the Advances evidenced by said Note all interest at any time contracted for, charged or received by the Bank in
connection therewith. If at any time and from time to time (i) the amount of interest payable to the Bank on any date shall be computed at the Bank’s Maximum Permissible Rate pursuant to this Section and (ii) in respect of any
subsequent interest computation period the amount of interest otherwise payable to the Bank would be less than the amount of interest payable to the Bank computed at the Bank’s Maximum Permissible Rate, then the amount of interest payable to
the Bank in respect of such subsequent interest computation period shall continue to be computed at the Bank’s Maximum Permissible Rate until the total amount of interest payable to the Bank shall equal the total amount of interest that would
have been payable to the Bank if the total amount of interest had been computed without giving effect to this Section.

losses, penalties, actions, judgments, suits, costs, expenses or disbursements of any kind or nature whatsoever to which any of them may become subject arising out of or based on the Loan Documents but excluding any such liabilities, obligations,

obligations of the Bank vis-a-vis the Borrower. 
 SECTION 10.12 Separability. Should any clause, sentence, paragraph or
Section of this Agreement be judicially declared to be invalid, unenforceable or void, such decision shall not have the effect of invalidating or voiding the remainder of this Agreement, and the parties hereto agree that the part or parts of this

inconsistency, the special rules shall control. Judgment upon any arbitration award may be entered in any court having jurisdiction. Any party to this Agreement may bring an action, including a summary or expedited proceeding, to compel arbitration
of any controversy or claim to which this Agreement or any of the Loan Documents applies in any court having jurisdiction over such action.

 -43- 

 
institution or maintenance of an action for foreclosure or provisional or ancillary remedies shall constitute a waiver of the right of any party, including the claimant in any such action, to
arbitrate the merits of the controversy or claim occasioning resort to such remedies.

 (i) With respect to any Letter of Credit, in accordance with the related Letter of Credit

(notwithstanding any minimum size or increment limitations on individual Revolving Advances). If the Borrower does not make such request and does not otherwise make the payments demanded by the Issuing Lender as required under this Agreement or the

the Issuing Lender, and the

  

 -26- 

 
Borrower hereby unconditionally and irrevocably authorizes, empowers, and directs the Lenders to make such Revolving Advance, to transfer the proceeds thereof to the Issuing Lender in
satisfaction of such obligations, and to record and otherwise treat such payments as a Revolving Advance to the Borrower. The Administrative Agent and each Lender may record and otherwise treat the making of such Revolving Borrowings as the making
of a Revolving Borrowing to the Borrower under this Agreement as if requested by the Borrower. Nothing herein is intended to release any of the Borrower’s obligations under any Letter of Credit Application, but only to provide an additional
method of payment therefor. The making of any Borrowing under this Section 2.2(c) shall not constitute a cure or waiver of any Default, other than the payment Default which is satisfied by the application of the amounts deemed advanced
hereunder, caused by the Borrower’s failure to comply with the provisions of this Agreement or the Letter of Credit Application. 
 (ii) Each Lender (including the Lender acting as Issuing Lender) shall, upon notice from the Administrative Agent that the Borrower has requested or is deemed to have requested a Revolving Advance
pursuant to Section 2.4 and regardless of whether (A) the conditions in Section 3.2 have been met, (B) such notice complies with Section 2.4, or (C) a Default exists, make funds available to the Administrative
Agent for the account of the Issuing Lender in an amount equal to such Lender’s Revolving Pro Rata Share of the amount of such Revolving Advance not later than 1:00 p.m. on the Business Day specified in such notice by the Administrative Agent,
whereupon each Lender that so makes funds available shall be deemed to have made a Revolving Advance to the Borrower in such amount. The Administrative Agent shall remit the funds so received to the Issuing Lender. 
 (iii) If any such Lender shall not have so made its Revolving Advance available to the Administrative Agent pursuant to this
Section 2.2, such Lender agrees to pay interest thereon for each day from such date until the date such amount is paid at the lesser of (A) the Federal Funds Rate for such day for the first three days and thereafter the interest
rate applicable to the Revolving Advance and (B) the Maximum Rate. Whenever, at any time after the Administrative Agent has received from any Lender such Lender’s Revolving Advance, the Administrative Agent receives any payment on account
thereof, the Administrative Agent will pay to such Lender its participating interest in such amount (appropriately adjusted, in the case of interest payments, to reflect the period of time during which such Lender’s Revolving Advance was
outstanding and funded), which payment shall be subject to repayment by such Lender if such payment received by the Administrative Agent is required to be returned. Each Lender’s obligation to make the Revolving Advance pursuant to this
Section 2.2 shall be absolute and unconditional and shall not be affected by any circumstance, including (1) any set-off, counterclaim, recoupment, defense or other right which such Lender or any other Person may have against the
Issuing Lender, the Administrative Agent or any other Person for any reason whatsoever; (2) the occurrence or continuance of a Default or the termination of the Commitments; (3) any breach of this Agreement by the Borrower or any other
Lender; or (4) any other circumstance, happening or event whatsoever, whether or not similar to any of the foregoing.

participation in the related Letter of Credit Obligations equal to such Lender’s Revolving Pro Rata Share at such date and such sale and purchase shall otherwise be in accordance with the terms of this Agreement. The Issuing Lender shall
promptly notify each such participant Lender by telex, telephone, or telecopy of each Letter of Credit issued or increased and the actual dollar amount of such Lender’s participation in such Letter of Credit. 
 (e) Obligations Unconditional. The obligations of the Borrower under this Agreement in respect of each Letter of Credit shall be
unconditional and irrevocable, and shall be paid strictly in accordance with the terms of this Agreement under all circumstances, notwithstanding the following circumstances: 
 (i) any lack of validity or enforceability of any Letter of Credit Documents; 
 (ii) any amendment or waiver of or any consent to departure from any Letter of Credit Documents; 
 (iii) the existence of any claim, set-off, defense or other right which any Credit Party may have at any time against any
beneficiary or transferee of such Letter of Credit (or any Persons for whom any such beneficiary or any such transferee may be acting), the Issuing Lender, any Lender or any other person or entity, whether in connection with this Agreement, the
transactions contemplated in this Agreement or in any Letter of Credit Documents or any unrelated transaction;

Issuing Lender under such Letter of Credit against presentation of a draft or certificate which does not comply with the terms of such Letter of Credit; or

Letter of Credit shall be outstanding or shall be drawn and not reimbursed on or prior to the 10th day prior to the Revolving Maturity Date, the Borrower shall pay to the Administrative Agent an amount equal to 105% of the Letter of Credit Exposure allocable to such Letter of Credit, such amount to be
due and payable on the 10th day prior to the Revolving
Maturity Date, and to be held in the Cash Collateral Account and applied in accordance with paragraph (i) below. 
 (g)
Liability of Issuing Lender. The Borrower assumes all risks of the acts or omissions of any beneficiary or transferee of any Letter of Credit with respect to its use of such Letter of Credit. Neither the Issuing Lender nor any of its officers
or directors shall be liable or responsible for: 
 (i) the use which may be made of any Letter of Credit or any
acts or omissions of any beneficiary or transferee in connection therewith; 
 (ii) the validity, sufficiency or
genuineness of documents, or of any endorsement thereon, even if such documents should prove to be in any or all respects invalid, insufficient, fraudulent or forged;

Credit, including failure of any documents to bear any reference or adequate reference to the relevant Letter of Credit; or

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

 -29- 

 (ii) Funds held in the Cash Collateral Account shall be held as cash
collateral for obligations with respect to Letters of Credit and promptly applied by the Administrative Agent at the request of the Issuing Lender to any reimbursement or other obligations under Letters of Credit that exist or occur. To the extent
that any surplus funds are held in the Cash Collateral Account above the Letter of Credit Exposure during the existence of an Event of Default the Administrative Agent may (A) hold such surplus funds in the Cash Collateral Account as cash
collateral for the Secured Obligations or (B) apply such surplus funds to any Secured Obligations in any manner directed by the Majority Lenders. If no Default exists, the Administrative Agent shall release to the Borrower at the
Borrower’s written request any funds held in the Cash Collateral Account above the amounts required by Section 2.2(f). 
 (iii) Funds held in the Cash Collateral Account shall be invested in Liquid Investments maintained with, and under the sole dominion and control of, the Administrative Agent or in another investment if
mutually agreed upon by the Borrower and the Administrative Agent, but the Administrative Agent shall have no other obligation to make any other investment of the funds therein. The Administrative Agent shall exercise reasonable care in the custody
and preservation of any funds held in the Cash Collateral Account and shall be deemed to have exercised such care if such funds are accorded treatment substantially equivalent to that which the Administrative Agent accords its own property, it being
understood that the Administrative Agent shall not have any responsibility for taking any necessary steps to preserve rights against any parties with respect to any such funds. 
 (i) Letters of Credit Issued for Guarantors. Notwithstanding that a Letter of Credit issued or outstanding hereunder is in support of
any obligations of, or is for the account of, a Guarantor or any Subsidiary, the Borrower shall be obligated to reimburse the Issuing Lender hereunder for any and all drawings under such Letter of Credit issued hereunder by the Issuing Lender. The
Borrower hereby acknowledges that the issuance of Letters of Credit for the account of any Guarantor, the Borrower or any Subsidiary inures to the benefit of the Borrower, and that the Borrower’s business (indirectly or directly) derives
substantial benefits from the businesses of such other Persons. 
 Section 2.3 Swing Line Advances. 
 (a) Commitment. On the terms and conditions set forth in this Agreement, and if an AutoBorrow Agreement is in effect, subject to the
terms and conditions of such AutoBorrow Agreement, the Swing Line Lender agrees to from time-to-time on any Business Day during the period from the date of this Agreement until the last Business Day occurring before the Revolving Maturity Date, make
Swing Line Advances under the Swing Line Note to the Borrower which shall be due and payable on the Swing Line Payment Date (except that no Swing Line Advance may mature after the Revolving Maturity Date), bearing interest at the Adjusted Base Rate
plus the Applicable Margin for Base Rate Advances, and in an aggregate principal amount not to exceed the Swing Line Commitment outstanding at any time; provided that (i) after giving effect to such Swing Line Advance, the sum of the
aggregate outstanding amount of all Revolving Advances plus the Letter of Credit Exposure plus the aggregate outstanding amount of all Swing Line Advances, shall not exceed the aggregate Revolving Commitments in effect at such time;
(ii) no Swing Line Advance shall be made by the Swing Line Lender if the conditions set forth in Section 3.2 have not been met as of the date of such Swing Line Advance, it being agreed by the Borrower that the giving of the applicable
Notice of

  

 -30- 

 
Borrowing and the acceptance by the Borrower of the proceeds of such Swing Line Advance shall constitute a representation and warranty by the Borrower that on the date of such Swing Line Advance
such conditions have been met; (iii) each Swing Line Advance shall be in an aggregate amount not less than $250,000.00 and in integral multiples of $50,000.00 in excess thereof; and (iv) if an AutoBorrow Agreement is in effect, such
additional terms and conditions of such AutoBorrow Agreement shall have been satisifed. The indebtedness of the Borrower to the Swing Line Lender resulting from Swing Line Advances shall be evidenced by the Swing Line Note. No Lender shall have any
rights or obligations under any AutoBorrow Agreement, but each Lender shall have the obligation to purchase and fund risk participations in the Swing Line Advances and to refinance Swing Line Advances as provided below. 
 (b) Prepayment. Within the limits expressed in this Agreement, amounts advanced pursuant to Section 2.3(a) may from time to time
be borrowed, prepaid without penalty, and reborrowed. If the aggregate outstanding principal amount of the Swing Line Advances ever exceeds the Swing Line Commitment, the Borrower shall, upon receipt of written notice of such condition from the
Swing Line Lender and to the extent of such excess, prepay to the Swing Line Lender outstanding principal of the Swing Line Advances such that such excess is eliminated. If an AutoBorrow Agreement is in effect, each prepayment of a Swing Line
Borrowing shall be made as provided in such AutoBorrow Agreement. 
 (c) Reimbursements for Swing Line Obligations.

 (i) With respect to the Swing Line Advances and the interest, premium, fees, and other amounts owed by the
Borrower to the Swing Line Lender in connection with the Swing Line Advances, the Borrower agrees to pay to the Swing Line Lender such amounts when due and payable to the Swing Line Lender under the terms of this Agreement and, if an AutoBorrow
Agreement is in effect, in accordance with the terms of such AutoBorrow Agreement. If the Borrower does not pay to the Swing Line Lender any such amounts when due and payable to the Swing Line Lender, the Swing Line Lender may upon notice to the
Administrative Agent request the satisfaction of such obligation by the making of a Revolving Borrowing in the amount of any such amounts not paid when due and payable. Upon such request, the Borrower shall be deemed to have requested the making of
a Revolving Borrowing in the amount of such obligation and the transfer of the proceeds thereof to the Swing Line Lender. Such Revolving Borrowing shall bear interest based upon the Adjusted Base Rate plus the Applicable Margin for Base Rate
Advances. The Administrative Agent shall promptly forward notice of such Revolving Borrowing to the Borrower and the Lenders, and each Lender shall, regardless of whether (A) the conditions in Section 3.2 have been met, (B) such
notice complies with Section 2.4, or (C) a Default exists, make available such Lender’s ratable share of such Revolving Borrowing to the Administrative Agent, and the Administrative Agent shall promptly deliver the proceeds thereof to
the Swing Line Lender for application to such amounts owed to the Swing Line Lender. The Borrower hereby unconditionally and irrevocably authorizes, empowers, and directs the Swing Line Lender to make such requests for Revolving Borrowings on behalf
of the Borrower, and the Lenders to make Revolving Advances to the Administrative Agent for the benefit of the Swing Line Lender in satisfaction of such obligations. The Administrative Agent and each Lender may record and otherwise treat the making
of such Revolving Borrowings as

  

 -31- 

 
the making of a Revolving Borrowing to the Borrower under this Agreement as if requested by the Borrower. Nothing herein is intended to release the Borrower’s obligations under the Swing
Line Note, but only to provide an additional method of payment therefor. The making of any Borrowing under this Section 2.3(c) shall not constitute a cure or waiver of any Default or Event of Default, other than the payment Default or Event of
Default which is satisfied by the application of the amounts deemed advanced hereunder, caused by the Borrower’s failure to comply with the provisions of this Agreement or the Swing Line Note. 
 (ii) If at any time, the Revolving Commitments shall have expired or be terminated while any Swing Line Advance is
outstanding, each Lender, at the sole option of the Swing Line Lender, shall either (A) notwithstanding the expiration or termination of the Revolving Commitments, make a Revolving Advance as a Base Rate Advance, or (B) be deemed, without
further action by any Person, to have purchased from the Swing Line Lender a participation in such Swing Line Advance, in either case in an amount equal to the product of such Lender’s Revolving Pro Rata Share times the outstanding aggregate
principal balance of the Swing Line Advances. The Administrative Agent shall notify each such Lender of the amount of such Revolving Advance or participation, and such Lender will transfer to the Administrative Agent for the account of the Swing
Line Lender on the next Business Day following such notice, in immediately available funds, the amount of such Revolving Advance or participation. 
 (iii) If any such Lender shall not have so made its Revolving Advance or its percentage participation available to the Administrative Agent pursuant to this Section 2.3, such Lender agrees to
pay interest thereon for each day from such date until the date such amount is paid at the lesser of (A) the Federal Funds Rate for such day for the first three days and thereafter the interest rate applicable to the Revolving Advance and
(B) the Maximum Rate. Whenever, at any time after the Administrative Agent has received from any Lender such Lender’s Revolving Advance or participating interest in a Swing Line Advance, the Administrative Agent receives any payment on
account thereof, the Administrative Agent will pay to such Lender its participating interest in such amount (appropriately adjusted, in the case of interest payments, to reflect the period of time during which such Lender’s Revolving Advance or
participating interest was outstanding and funded), which payment shall be subject to repayment by such Lender if such payment received by the Administrative Agent is required to be returned. Each Lender’s obligation to make the Revolving
Advance or purchase such participating interests pursuant to this Section 2.3 shall be absolute and unconditional and shall not be affected by any circumstance, including (1) any set-off, counterclaim, recoupment, defense or other
right which such Lender or any other Person may have against the Swing Line Lender, the Administrative Agent or any other Person for any reason whatsoever; (2) the occurrence or continuance of a Default or the termination of the Commitments;
(3) any breach of this Agreement by the Borrower or any other Lender; or (4) any other circumstance, happening or event whatsoever, whether or not similar to any of the foregoing. Each Swing Line Advance, once so participated by any
Lender, shall cease to be a Swing Line Advance with respect to that amount for purposes of this Agreement, but shall continue to be a Revolving Loan. 
  

 -32- 

 (d) Method of Borrowing. If an AutoBorrow Agreement is in effect, each Swing Line
Borrowing shall be made as provided in such AutoBorrow Agreement. Otherwise, and except as provided in the clause (c) above, each request for a Swing Line Advance shall be made pursuant to telephone notice to the Swing Line Lender given no
later than 1:00 p.m. (Houston, Texas time) on the date of the proposed Swing Line Advance, promptly confirmed by a completed and executed Notice of Borrowing telecopied or facsimiled to the Administrative Agent and the Swing Line Lender. The Swing
Line Lender will promptly make the Swing Line Advance available to the Borrower at the Borrower’s account with the Administrative Agent. 
 (e) Interest for Account of Swing Line Lender. Swing Line Lender shall be responsible for invoicing the Borrower for interest on the Swing Line Advances (provided that any failure of the
Swing Line Lender to provide such invoice shall not release the Borrower from its obligation to pay such interest). Until each Lender funds its Revolving Advance or risk participation pursuant to clause (c) above, interest in respect of
Lender’s Pro Rata Share of the Swing Line Advances shall be solely for the account of the Swing Line Lender. 
 (f)
Payments Directly to Swing Line Lenders. The Borrower shall make all payments of principal and interest in respect of the Swing Line Advances directly to the Swing Line Lender. 
 (g) Termination of Swing Line Sublimit. Swing Line Lender may terminate and/or suspend its Swing Line Commitment in accordance with
any applicable AutoBorrow Agreement. 
 Section 2.4 Advances.

at its address referred to in Section 9.9, or such other location as the Administrative Agent may specify by notice to the Lenders, in same day funds, such Lender’s Revolving Pro Rata Share of such Borrowing. After the Administrative
Agent’s receipt of such funds and upon fulfillment of the applicable conditions set forth in Article 3, the Administrative Agent will make such funds available to the Borrower at its account with the Administrative Agent or as otherwise
directed by the Borrower with written notice to the Administrative Agent. 
  

 -33- 

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

 -34- 

 (v) if the Majority Lenders shall, at least one Business Day before the date
of any requested Borrowing, notify the Administrative Agent that the Eurodollar Rate for Eurodollar Advances comprising such Borrowing will not adequately reflect the cost to such Lenders of making or funding their respective Eurodollar Advances, as
the case may be, for such Borrowing, the right of the Borrower to select Eurodollar Advances for such Borrowing or for any subsequent Borrowing shall be suspended until the Administrative Agent shall notify the Borrower and the Lenders that the
circumstances causing such suspension no longer exist, and each Advance comprising such Borrowing shall be a Base Rate Advance; and 
 (vi) if the Borrower shall fail to select the duration or continuation of any Interest Period for any Eurodollar Advances in accordance with the provisions contained in the definition of Interest Period
in Section 1.1 and paragraph (b) above, the Administrative Agent will forthwith so notify the Borrower and the Lenders and such Advances will be made available to the Borrower on the date of such Borrowing as Base Rate Advances or, if an
existing Advance, Convert into Base Rate Advances. 
 (d) Notices Irrevocable. Each Notice of Borrowing and Notice of
Continuation or Conversion delivered by the Borrower hereunder, including its request for borrowing made under Section 2.1(e), shall be irrevocable and binding on the Borrower. 
 (e) Administrative Agent Reliance. Unless the Administrative Agent shall have received notice from a Lender before the date of any
Term Borrowing or Revolving Borrowing that such Lender will not make available to the Administrative Agent such Lender’s applicable pro rata share of any Borrowing, the Administrative Agent may assume that such Lender has made its applicable
pro rata share of such Borrowing available to the Administrative Agent on the date of such Borrowing in accordance with Section 2.4(a), and the Administrative Agent may, in reliance upon such assumption, make available to the Borrower on such
date a corresponding amount. If and to the extent that such Lender shall not have so made its applicable pro rata share of such Borrowing available to the Administrative Agent, such Lender and the Borrower severally agree to immediately repay to the
Administrative Agent on demand such corresponding amount, together with interest on such amount, for each day from the date such amount is made available to the Borrower until the date such amount is repaid to the Administrative Agent, at
(i) in the case of the Borrower, the interest rate applicable on such day to Advances comprising such Borrowing and (ii) in the case of such Lender, the lesser of (A) the Federal Funds Rate for such day and (B) the Maximum Rate.
If such Lender shall repay to the Administrative Agent such corresponding amount and interest as provided above, such corresponding amount so repaid shall constitute such Lender’s Advance as part of such Borrowing for purposes of this Agreement
even though not made on the same day as the other Advances comprising such Borrowing.

Advance of such Lender, from the date such requirement is imposed until the earlier of (i) the date such requirement is no longer imposed and (ii) the date on which such principal amount is paid in full, at an interest rate per annum equal
at all times to the remainder obtained by subtracting (A) the Eurodollar Rate for the Interest Period for such Eurodollar Advance from (B) the rate obtained by dividing such Eurodollar Rate by a percentage equal to 100% minus the
Eurodollar Rate Reserve Percentage of such Lender for such Interest Period, payable on each date on which interest is payable on such Advance. Such additional interest payable hereunder to the Administrative Agent for the ratable account of any
applicable Lender shall be determined in good faith by such Lender and notified to the Administrative Agent and the Borrower at least three Business Days before each date on which such interest is payable (such notice to include the calculation of
such additional interest, which calculation shall be conclusive in the absence of manifest error). 
 (d) Retroactive
Adjustments of Applicable Margin. In the event that any financial statement or Compliance Certificate delivered pursuant to Section 5.2 is shown to be inaccurate (regardless of whether this Agreement or the Commitments are in effect when
such inaccuracy is discovered), and such inaccuracy, if corrected, would have led to the application of a higher Applicable Margin for any period (an “Applicable Period”) than the Applicable Margin applied for such Applicable
Period, then (i) the Borrower shall immediately deliver to the Administrative Agent a corrected Compliance Certificate for such Applicable Period, (ii) the Applicable Margin shall be determined as if the higher Applicable Margin that would
have applied were applicable for such Applicable Period (and in any event at Level 6 if the inaccuracy was the result of dishonesty, fraud or willful misconduct), and (iii) the Borrower shall immediately, without further action by the
Administrative Agent, any Lender or the Issuing Lender, pay to the Administrative Agent for the account of the applicable Lenders, the accrued additional interest owing as a result of such increased Applicable Margin for such Applicable Period. This
Section 2.8(d) shall not limit the rights of the Administrative Agent and Lenders with respect to the default rate of interest as set forth in Section 2.8(a) and Section 2.8(b) and Article VII. The Borrower’s obligations under
this Section 2.8(d) shall survive the termination of the Commitments and the repayment of all other Secured Obligations hereunder. 
 Section 2.9 Illegality. If any Lender shall notify the Borrower that the introduction of or any change in or in the interpretation of any law or regulation makes it unlawful, or that any central
bank or other governmental authority asserts that it is unlawful, for such Lender or its Applicable Lending Office to perform its obligations under this Agreement to make, maintain, or fund any Eurodollar Advances of such Lender then outstanding
hereunder, (a) the Borrower shall, no later than 11:00 a.m. (Houston, Texas, time) (i) if not prohibited by law, on the last day

  

 -40- 

 
of the Interest Period for each outstanding Eurodollar Advance or (ii) if required by such notice, on the second Business Day following its receipt of such notice, prepay all of the
Eurodollar Advances of such Lender then outstanding, together with accrued interest on the principal amount prepaid to the date of such prepayment and amounts, if any, required to be paid pursuant to Section 2.10 as a result of such prepayment
being made on such date, (b) such Lender shall simultaneously make a Base Rate Advance to the Borrower on such date in an amount equal to the aggregate principal amount of the Eurodollar Advances prepaid to such Lender, and (c) the right
of the Borrower to select Eurodollar Advances from such Lender for any subsequent Borrowing shall be suspended until such Lender shall notify the Borrower that the circumstances causing such suspension no longer exist. Each Lender agrees to use
commercially reasonable efforts (consistent with its internal policies and legal and regulatory restrictions) to designate a different Applicable Lending Office if the making of such designation would avoid the effect of this paragraph and would
not, in the reasonable judgment of such Lender, be otherwise disadvantageous to such Lender. 
 Section 2.10 Breakage
Costs. 
 (a) Funding Losses. In the case of any Revolving Borrowing which the related Notice of Borrowing specifies
is to be comprised of Eurodollar Advances, the Borrower shall indemnify each Lender against any loss, out-of-pocket cost, or expense incurred by such Lender as a result of any failure to fulfill on or before the date specified in such Notice of
Borrowing for such Borrowing the applicable conditions set forth in Article 3, including, without limitation, any loss (excluding any loss of anticipated profits), cost, or expense incurred by reason of the liquidation or redeployment of deposits or
other funds acquired by such Lender to fund the Eurodollar Advance to be made by such Lender as part of such Borrowing when such Eurodollar Advance, as a result of such failure, is not made on such date. 
 (b) Prepayment Losses. If (i) any payment of principal of any Eurodollar Advance is made other than on the last day of the
Interest Period for such Advance as a result of any prepayment, payment pursuant to Section 2.9, the acceleration of the maturity of the Notes, or for any other reason or (ii) the Borrower fails to make a principal or interest payment with
respect to any Eurodollar Advance on the date such payment is due and payable, the Borrower shall, within 10 days of any written demand sent by the Administrative Agent on behalf of a Lender to the Borrower, pay to the Administrative Agent for the
benefit of such Lender any amounts determined in good faith by such Lender to be required to compensate such Lender for any additional losses, out-of-pocket costs, or expenses which it may reasonably incur as a result of such payment or nonpayment,
including, without limitation, any loss (excluding loss of anticipated profits), cost, or expense incurred by reason of the liquidation or reemployment of deposits or other funds acquired by any Lender to fund or maintain such Advance. 

Section 2.11 Increased Costs. 
 (a) Eurodollar Advances. If, after the Effective Date, the adoption of any applicable law, rule, or regulation, or any change in any applicable law, rule, or regulation, or any change in the
interpretation or administration thereof by any governmental authority, central bank, or comparable agency charged with the interpretation or administration thereof, or compliance by financial institutions generally, including a Lender (or its
Applicable Lending Office) with any request or directive (whether or not having the force of law) of any such governmental authority, central bank, or comparable agency: 
 (i) shall impose, modify, or deem applicable any reserve, special deposit, assessment, or similar requirement (other than by
way of imposition or increase of reserve requirements included in the Eurodollar Rate Reserve Percentage) relating to any extensions of credit or other assets of, or any deposits with or other liabilities or commitments of, financial institutions
generally, including such Lender (or its Applicable Lending Office), including the Commitments of such Lender hereunder; or 
  

 -41- 

 (ii) shall impose on financial institutions generally, including such Lender
(or its Applicable Lending Office), or on the London interbank market any other condition affecting this Agreement or its Notes or any of such extensions of credit or liabilities or commitments; 
 and the result of any of the foregoing is to increase the cost to such Lender (or its Applicable Lending Office) of making, Converting into, continuing, or
maintaining any Eurodollar Advances or to reduce any sum received or receivable by such Lender (or its Applicable Lending Office) under this Agreement or its Notes with respect to any Eurodollar Advances, then the Borrower shall pay to such Lender
within three Business Days after written demand made by such Lender such amount or amounts as such Lender determines in good faith to be necessary to compensate such Lender for such increased cost or reduction. 
 (b) Capital Adequacy. If, after the Effective Date, any Lender or the Issuing Lender shall have determined that the adoption of any
applicable law, rule, or regulation regarding capital adequacy or any change therein or in the interpretation or administration thereof by any governmental authority, central bank, or comparable agency charged with the interpretation or
administration thereof, or any request or directive regarding capital adequacy (whether or not having the force of law) of any such governmental authority, central bank, or comparable agency, has or would have the effect of reducing the rate of
return on the capital of financial institutions generally, including such Lender or the Issuing Lender or any corporation controlling such Lender or the Issuing Lender, as a consequence of such Lender’s or the Issuing Lender’s obligations
hereunder to a level below that which such Lender or the Issuing Lender or such corporation could have achieved but for such adoption, change, request, or directive (taking into consideration its policies with respect to capital adequacy), then from
time to time within three Business Days after written demand by such Lender or the Issuing Lender, as the case may be, the Borrower shall pay to such Lender or the Issuing Lender such additional amount or amounts as such Lender determines in good
faith to be necessary to compensate such Lender or the Issuing Lender for such reduction. 
 (c) Mitigation. Each Lender
shall promptly notify the Borrower and the Administrative Agent of any event of which it has knowledge, occurring after the Effective Date, which will entitle such Lender to compensation pursuant to this Section 2.11 and will designate a
different Applicable Lending Office if such designation will avoid the need for, or reduce the amount of, such compensation and will not, in the reasonable judgment of such Lender, be otherwise disadvantageous to it. Any Lender claiming compensation
under this Section 2.11 shall furnish to the Borrower and the Administrative Agent a statement setting forth the additional amount or amounts to be paid to it hereunder which shall be determined by such Lender in good faith and which shall be
conclusive in the absence of manifest error. In determining such amount, such Lender may use any reasonable averaging and attribution methods. 
  

 -42- 

 Section 2.12 Payments and Computations. 
 (a) Payments. All payments of principal, interest, and other amounts to be made by the Borrower under this Agreement and other Credit
Documents shall be made to the Administrative Agent in Dollars and in immediately available funds, without setoff, deduction, or counterclaim. 
 (b) Payment Procedures. The Borrower shall make each payment under this Agreement and under the Notes not later than 11:00 a.m. (Houston, Texas time) on the day when due in Dollars to the
Administrative Agent at the location referred to in the Notes (or such other location as the Administrative Agent shall designate in writing to the Borrower) in same day funds. The Administrative Agent will promptly thereafter, and in any event
prior to the close of business on the day any timely payment is made, cause to be distributed like funds relating to the payment of principal, interest or fees ratably (other than amounts payable solely to the Administrative Agent or a specific
Lender pursuant to Sections 2.8(c), 2.9, 2.10, 2.11, 2.13, and 9.2 but after taking into account payments effected pursuant to Section 9.1) in accordance with each Lender’s applicable pro rata share to the Lenders for the account of their
respective Applicable Lending Offices, and like funds relating to the payment of any other amount payable to any Lender to such Lender for the account of its Applicable Lending Office, in each case to be applied in accordance with the terms of this
Agreement. Upon receipt of other amounts due solely to the Administrative Agent, the Issuing Lender, the Swing Line Lender, or a specific Lender, the Administrative Agent shall distribute such amounts to the appropriate party to be applied in
accordance with the terms of this Agreement. 
 (c) Non-Business Day Payments. Whenever any payment shall be stated to be
due on a day other than a Business Day, such payment shall be made on the next succeeding Business Day, and such extension of time shall in such case be included in the computation of payment of interest or fees, as the case may be; provided
that if such extension would cause payment of interest on or principal of Eurodollar Advances to be made in the next following calendar month, such payment shall be made on the next preceding Business Day. 
 (d) Computations. All computations of interest and fees shall be made by the Administrative Agent on the basis of a year of 365/366
days for Base Rate Advances and a year of 360 days for all other interest and fees, in each case for the actual number of days (including the first day, but excluding the last day) occurring in the period for which such interest or fees are payable.
Each determination by the Administrative Agent of an amount of interest or fees shall be conclusive and binding for all purposes, absent manifest error. 
 (e) Sharing of Payments, Etc. If any Lender shall obtain any payment (whether voluntary, involuntary, through the exercise of any right of set-off, or otherwise) on account of the Advances made by
it in excess of its ratable share of payments on account of the Advances or Letter of Credit Obligations obtained by the Lenders, such Lender shall notify the other Lenders

  

 -43- 

 
and forthwith purchase from the other Lenders such participations in the Advances made by it or the Letter of Credit Obligations held by it as shall be necessary to cause such purchasing Lender
to share the excess payment ratably with the other Lenders; provided that if all or any portion of such excess payment is thereafter recovered from such purchasing Lender, such purchase from the other Lenders shall be rescinded and each such
Lender shall repay to the purchasing Lender the purchase price to the extent of such Lender’s ratable share, but without interest. The Borrower agrees that any Lender so purchasing a participation from another Lender pursuant to this
Section 2.12(e) may, to the fullest extent permitted by law, exercise all its rights of payment (including the right of set-off) with respect to such participation as fully as if such Lender were the direct creditor of the Borrower in the
amount of such participation. 
 Section 2.13 Taxes. 
 (a) No Deduction for Certain Taxes. Any and all payments by the Borrower under any of the Credit Documents to the Administrative
Agent, the Issuing Lender, or a Lender shall be made, in accordance with Section 2.12, free and clear of and without deduction for any and all present or future taxes, levies, imposts, deductions, charges, or withholdings, and all liabilities
with respect thereto, excluding, in the case of the Administrative Agent, the Issuing Lender, or a Lender, (i) taxes imposed on its income and franchise or similar taxes imposed on it by the jurisdiction (or any political subdivision thereof)
under the laws of which (or under the laws of a political subdivision of which) (A) the Administrative Agent, the Issuing Lender, or such Lender is organized or in which its principal executive office is located or (B) in the case of each
Lender, such Lender’s Applicable Lending Office is located and (ii) any taxes imposed by the United States of America by means of withholding at the source, if and to the extent such United States withholding taxes are in effect on the
date a Lender becomes a Lender hereunder (all such nonexcluded taxes, levies, imposts, deductions, charges, withholdings, and liabilities being hereinafter referred to as “Taxes”). Except as provided in Section 2.13(f), if the
Borrower shall be required by law to deduct any Taxes from or in respect of any sum payable to the Administrative Agent, the Issuing Lender, or any Lender, (i) the sum payable shall be increased as may be necessary so that, after making all
required deductions (including deductions applicable to additional sums payable under this Section 2.13), such Lender receives an amount equal to the sum it would have received had no such deductions been made; (ii) the Borrower shall make
such deductions; and (iii) the Borrower shall pay the full amount deducted to the relevant Governmental Authority or other authority in accordance with applicable law. 
 (b) Other Taxes. In addition, except as provided in Section 2.13(f), the Borrower agrees to pay any present or future stamp or
documentary taxes or any other excise or property taxes, charges, or similar levies which arise from any payment made under any Credit Document or from the execution, delivery, or registration of, or otherwise with respect to, this Agreement, the
Notes, or the other Credit Documents (hereinafter referred to as “Other Taxes”). 
 (c) Indemnification. EXCEPT
AS PROVIDED IN SECTION 2.13(F), THE BORROWER INDEMNIFIES EACH LENDER, THE ISSUING LENDER, AND THE ADMINISTRATIVE AGENT FOR THE FULL AMOUNT OF TAXES OR OTHER TAXES (INCLUDING, WITHOUT LIMITATION, ANY TAXES OR OTHER TAXES IMPOSED ON AMOUNTS PAYABLE
UNDER THIS SECTION 2.13) PAID BY SUCH LENDER, THE ISSUING LENDER, OR THE ADMINISTRATIVE AGENT (AS THE CASE MAY BE) AND ANY LIABILITY (INCLUDING INTEREST AND EXPENSES) ARISING THEREFROM OR WITH RESPECT THERETO, WHETHER OR NOT SUCH TAXES OR OTHER
TAXES WERE CORRECTLY OR LEGALLY ASSERTED. 
  

 -44- 

 (d) Evidence of Tax Payments. As soon as practicable after any payment of Taxes or
Other Taxes by the Borrower to a Governmental Authority, the Borrower shall deliver to the Administrative Agent the original or a certified copy of any receipt issued by such Governmental Authority evidencing such payment. 
 (e) Foreign Lender Withholding Exemption. Each Lender that is not incorporated under the laws of the United States of America or a
state thereof and that is entitled to an exemption from United States withholding tax with respect to payments under this Agreement under applicable law or any treaty to which the United States is a party shall deliver to the Borrower (with a copy
to the Administrative Agent), at the time or times prescribed by applicable law, such properly completed and executed documentation (including Internal Revenue Service Forms W-8BEN or W-8ECI) prescribed by applicable law or reasonably requested by
the Borrower as will permit such payments to be made without withholding. 
 (f) Failure to Provide Forms. For any period
with respect to which a Lender has failed to provide the Borrower or the Administrative Agent with the appropriate forms referred to in this Section 2.13 (unless such failure is due to a change in treaty, law or regulation occurring after the
date on which such Lender becomes a Lender hereunder), such Lender shall not be entitled to indemnification or payment under the Section 2.13(a), (b), or (c) with respect to Taxes imposed by the United States; provided that if a
Lender, that is otherwise exempt from or subject to a reduced rate of withholding tax, becomes subject to Taxes because of its failure to deliver a form required hereunder, the Borrower shall take such steps as such Lender shall reasonably request,
and at the expenses of such Lender, to assist such Lender to recover such Taxes. 
 (g) Mitigation. Each Lender shall use
reasonable efforts (consistent with its internal policies and legal and regulatory restrictions) to select a jurisdiction for its Applicable Lending Office or change the jurisdiction of its Applicable Lending Office, as the case may be, so as to
avoid the imposition of any Taxes or Other Taxes or to eliminate or reduce the payment of any additional sums under this Section 2.13; provided, that no such selection or change of jurisdiction for its Applicable Lending Office shall be made
if, in the reasonable judgment of such Lender, such selection or change would be disadvantageous to such Lender. 
 (h) Tax
Credits and Refunds. If the Administrative Agent, the Issuing Lender, or a Lender has determined that it has received a refund of any Taxes or Other Taxes as to which it has been indemnified by the Borrower or with respect to which the Borrower
has paid additional sums pursuant to this Section 2.13, or if the Administrative Agent or a Lender has determined that it received a credit from any Governmental Authority to which the Administrative Agent or such Lender would not be entitled
but for the payment by the Borrower of Taxes, Other Taxes or additional sums pursuant to this Section 2.13, at the Borrower’s request it shall pay over the amount of such refund or credit to the Borrower (but only to the extent of
indemnity payments made, or additional sums paid, by the Borrower under this Section 2.13 with respect to the Taxes or Other Taxes giving rise to such refund or credit), net of all out-of-pocket expenses of the Administrative Agent or such
Lender and without interest (other than any interest paid by the

  

 -45- 

 
relevant Governmental Authority with respect to such refund or credit); provided, that the Borrower, upon the request of the Administrative Agent or such Lender, agrees to repay the amount paid
over to the Borrower (plus any penalties, interest or other charges imposed by the relevant Governmental Authority) to the Administrative Agent or such Lender in the event and to the extent that the Administrative Agent or such Lender is required to
repay such refund or credit to such Governmental Authority. 
 (i) Payment. If the Administrative Agent or any Lender
becomes entitled to receive payment of Taxes, Other Taxes or additional sums pursuant to this Section 2.13, it shall give notice and demand thereof to the Borrower, and the Borrower (unless the Administrative Agent or Lender shall withdraw such
notice and demand or the Borrower is not obligated to pay such amounts) shall pay such Taxes, Other Taxes or additional sums within 30 days after the Borrower’s receipt of such notice and demand. 
 Section 2.14 Replacement of Lenders. If the Borrower is required pursuant to Section 2.8(c), 2.11 or 2.13 to make any additional
payment to any Lender or if any Lender’s obligation to make or continue, or to convert Base Rate Advances into, Eurodollar Advances shall be suspended pursuant to 2.4(c)(iii) or 2.9, or if any Lender shall fail to fund its portion of any
Advance required pursuant to the terms hereof (any Lender so affected, an “Affected Lender”), the Borrower may elect, if such amounts continue to be charged or such suspension is still effective, to replace such Affected Lender as a
Lender party to this Agreement, provided that (a) no Default shall have occurred and be continuing at the time of such replacement; (b) such replacement shall be at the Borrower’s sole expense and effort, including the payment
of the processing fee referenced in Section 9.7(a)); (c) concurrently with such replacement, another bank or other entity (which entity shall be an Eligible Assignee), as of such date, shall purchase for cash the Advances and other
Obligations due to the Affected Lender pursuant to an assignment substantially in the form of Exhibit A and shall become a Lender for all purposes under this Agreement and shall assume all obligations of the Affected Lender which as to the Affected
Lender shall be terminated as of such date and shall comply with the requirements of Section 9.7 applicable to assignments; and (d) concurrently with such replacement, the Borrower shall pay to such Affected Lender in same day funds on the
day of such replacement all interest, fees and other amounts then accrued but unpaid to such Affected Lender by the Borrower hereunder to and including the date of termination, including without limitation payments due to such Affected Lender under
Sections 2.8(c), 2.11 and 2.13. 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 Issuing Lender, as applicable, or otherwise, the circumstances entitling the
Borrower to require such assignment and delegation cease to apply. 
 Section 2.15 Increase in Commitments. 

(a) At any time prior to the Revolving Maturity Date, the Borrower may effectuate increases in the aggregate Revolving Commitments (each
such increase being a “Commitment Increase”), by designating either one or more of the existing Lenders (each of which, in its sole discretion, may determine whether and to what degree to participate in such Commitment Increase) or
one or more other Eligible Assignees that at the time agree, in the case of any such Eligible Assignee that is an existing Lender to increase its Revolving Commitment as such Lender shall so select (an “Increasing Lender”) and, in
the case of any other Eligible Assignee

  

 -46- 

 
that is not an existing Lender (an “Additional Lender”), to become a party to this Agreement as a Revolving Lender; provided, however, that (i) each Commitment
Increase shall be of at least $1,000,000, (ii) the aggregate amount of all Commitment Increases shall not exceed $15,000,000 and the aggregate Revolving Commitments, after giving effect to all Commitment Increases, shall not exceed $40,000,000,
and (iii) all Revolving Commitments and Revolving Advances provided pursuant to a Commitment Increase shall be available on the same terms as those applicable to the existing Revolving Commitments and Revolving Advances. The sum of the
increases in the Revolving Commitments of the Increasing Lenders plus the Revolving Commitments of the Additional Lenders upon giving effect to a Commitment Increase shall not, in the aggregate, exceed the amount of such Commitment Increase. The
Borrower shall provide prompt notice of any proposed Commitment Increase pursuant to this Section 2.15 to the Administrative Agent and the Lenders. This Section 2.15 shall not be construed to create any obligation on the Administrative
Agent or any of the Lenders to advance or to commit to advance any credit to the Borrower or to arrange for any other Person to advance or to commit to advance any credit to the Borrower. 
 (b) A Commitment Increase shall become effective on the date (the “Increase Date”) on or prior to which the following
conditions shall have been satisfied: (i) the receipt by the Administrative Agent of (A) an agreement in form and substance reasonably satisfactory to the Administrative Agent signed by the Borrower, each Increasing Lender and each
Additional Lender, setting forth the Revolving Commitments, if any, of each such Lender and setting forth the agreement of each Additional Lender to become a party to this Agreement and to be bound by all the terms and provisions hereof binding upon
each Lender, and (B) such evidence of appropriate authorization on the part of the Borrower with respect to such Commitment Increase as the Administrative Agent may reasonably request, (ii) the funding by each Increasing Lender and
Additional Lender of the Advances to be made by each such Lender to effect the prepayment requirement set forth in Section 2.4(c)(vii), and (iii) receipt by the Administrative Agent of a certificate of an authorized officer of the Borrower
stating that, both before and after giving effect to such Commitment Increase, no Default has occurred and is continuing, and that all representations and warranties made by the Borrower in this Agreement are true and correct in all material
respects, unless such representation or warranty relates to an earlier date which remains true and correct in all material respects as of such earlier date. 
 (c) Notwithstanding any provision contained herein to the contrary, from and after the date of any Commitment Increase, all calculations and payments of interest on the Revolving Advances shall take into
account the actual Revolving Commitment of each Lender and the principal amount outstanding of each Revolving Advance made by such Lender during the relevant period of time. 
 (d) On each Increase Date, each Lender’s share of the Letter of Credit Exposure on such date shall automatically be deemed to equal
such Lender’s applicable pro rata share of such Letter of Credit Obligations (such pro rata share for such Lender to be determined as of the Increase Date in accordance with its Revolving Commitment on such date as a percentage of the aggregate
Revolving Commitment on such date) without further action by any party.

Additionally, except as disclosed in writing to the Administrative Agent and the Lenders, there is no pending or, to the knowledge of the Borrower, threatened action or proceeding instituted against any of the Borrower or any of Subsidiary of the

under any law relating to bankruptcy, insolvency or reorganization or relief of debtors, or seeking the entry of an order for relief or the appointment of a receiver, trustee or other similar official for it or for any substantial part of its
Property; provided that this Section 4.7 does not apply with respect to Environmental Claims. 
 Section 4.8 Compliance
with Agreements. 
 (a) Neither the Borrower nor any of its Subsidiaries is a party to any indenture, loan or credit
agreement or any lease or any other types of agreement or instrument or subject to any charter or corporate restriction or provision of applicable law or governmental regulation the performance of or compliance with which could reasonably be
expected to cause a Material Adverse Change. Neither the Borrower nor any of its Subsidiaries is in default under or with respect to any contract, agreement, lease or any other types of agreement or instrument to which the Borrower or such
Subsidiary is a party and which could reasonably be expected to cause a Material Adverse Change. To the best knowledge of the Borrower, neither the Borrower nor any of its Subsidiaries is in default under, or has received a notice of default under,
any contract, agreement, lease or any other document or instrument to which the Borrower or its Subsidiaries is a party which is continuing and which, if not cured, could reasonably be expected to cause a Material Adverse Change. 
 (b) No Default has occurred and is continuing. 
 Section 4.9 Pension Plans. (a) Except for matters that could not reasonably be expected to result in a Material Adverse Change, all Plans are in compliance in all material respects with all
applicable provisions of ERISA, (b) no Termination Event has occurred with respect to any Plan that would result in an Event of Default under Section 7.1(i), and, except for matters that could not reasonably be expected to result in a
Material Adverse Change, each Plan has complied with and been administered in all material respects in accordance with applicable provisions of ERISA and the Code, (c) no “accumulated funding deficiency” (as defined in
Section 302 of ERISA) has occurred, and for plan years after December 31, 2007, no unpaid minimum required contribution exists, and there has been no excise tax imposed under Section 4971 of the Code, (d) to the knowledge of
Borrower, no Reportable Event has occurred with respect to any Multiemployer Plan, and each Multiemployer Plan has complied with and been administered in accordance with applicable provisions of ERISA and the Code, (e) the

  

 -54- 

 
present value of all benefits vested under each Plan (based on the assumptions used to fund such Plan) did not, as of the last annual valuation date applicable thereto, exceed the value of the
assets of such Plan allocable to such vested benefits in an amount that could reasonably be expected to result in a Material Adverse Change, (f) neither the Borrower nor any member of the Controlled Group has had a complete or partial
withdrawal from any Multiemployer Plan for which there is any unsatisfied withdrawal liability that could reasonably be expected to result in a Material Adverse Change or an Event of Default under Section 7.1(j), and (g) except for matters
that could not reasonably result in a Material Adverse Change, as of the most recent valuation date applicable thereto, neither the Borrower nor any member of the Controlled Group would become subject to any liability under ERISA if the Borrower or
any Subsidiary of the Borrower has received notice that any Multiemployer Plan is insolvent or in reorganization. Based upon GAAP existing as of the date of this Agreement and current factual circumstances, the Borrower has no reason to believe that
the annual cost during the term of this Agreement to the Borrower or any Subsidiary of the Borrower for post-retirement benefits to be provided to the current and former employees of the Borrower or any Subsidiary of the Borrower under Plans that
are welfare benefit plans (as defined in Section 3(1) of ERISA) could, in the aggregate, reasonably be expected to cause a Material Adverse Change.

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

Agreement, termination of all Hedging Agreements with such Persons, termination of all Letters of Credit, and the payment in full of all outstanding Advances, Letter of Credit Obligations and all other Secured Obligations payable under this
Agreement and under any other Credit Document; (b) constituting property sold or to be sold or disposed of as part of or in connection with any disposition permitted under this Agreement or any other Credit Document; (c) constituting
property in which no Credit Party owned an interest at the time the Lien was granted or at any time thereafter; or (d) constituting property leased to any Credit Party under a lease which has expired or has been terminated in a transaction
permitted under this Agreement or is about to expire and which has not been, and is not intended by such Credit Party to be, renewed or extended; and (ii) release a Guarantor from its obligations under a Guaranty and any other applicable Credit
Document if such Person ceases to be a Subsidiary as a result of a transaction permitted under this Agreement. Upon the request of the Administrative Agent at any time, the Secured Parties will confirm in writing the Administrative Agent’s
authority to release particular types or items of Collateral pursuant to this Section 8.8.

Agreement, the Notes, or any other Credit Document, nor consent to any departure by the Borrower or any Guarantor therefrom, shall in any event be effective unless the same shall be in writing and signed by the Majority Lenders and the Borrower, and

aggregate Revolving Commitments over the sum of (i) the aggregate outstanding amount

  

 -84-

above to take such action, affect the rights or duties of the Administrative Agent under this Agreement or any other Credit Document; 
 (h) no amendment, waiver or consent shall, unless in writing and signed by the Issuing Lender in addition to the Lenders required above to take such action, affect the rights or duties of the Issuing Lender under this Agreement or any other
Credit Document; and 
 (i) no amendment, waiver or consent shall, unless in writing and signed by the Swing Line Lender in
addition to the Lenders required above to take such action, affect the rights or duties of the Swing Line Lender under this Agreement or any other Credit Document. 
 Section 9.4 Severability. In case one or more provisions of this Agreement or the other Credit Documents shall be invalid, illegal or unenforceable in any respect under any applicable law, the
validity, legality, and enforceability of the remaining provisions contained herein or therein shall not be affected or impaired thereby. 
 Section 9.5 Survival of Representations and Obligations. All representations and warranties contained in this Agreement or made in writing by or on behalf of the Borrower in connection herewith
shall survive the execution and delivery of this Agreement and the other Credit Documents, the making of the Advances or the issuance of any Letters of Credit and any investigation made by or on behalf of the Lenders, none of which investigations
shall diminish any Lender’s right to rely on such representations and warranties. All obligations of the Borrower provided for in Sections 2.10, 2.11, 2.13(c), 9.1 and 9.2 and all of the obligations of the Lenders in Section 8.5 shall
survive any termination of this Agreement and repayment in full of the Obligations. 
 Section 9.6 Binding Effect. This
Agreement shall become effective when it shall have been executed by the Borrower and the Administrative Agent, and when the Administrative Agent shall have, as to each Lender, either received a counterpart hereof executed by such Lender or been
notified by such Lender that such Lender has executed it and thereafter shall be binding upon and inure to the benefit of the Borrower, the Administrative Agent, and each Lender and their respective successors and assigns, except that neither the
Borrower nor any other Credit Party shall have the right to assign its rights or delegate its duties under this Agreement or any interest in this Agreement without the prior written consent of each Lender.

 Section 9.7 Lender Assignments and Participations. 
 (a) Each Lender may assign to one or more Eligible Assignees all or a portion of its rights and obligations under this Agreement (including,
without limitation, all or a portion of its Advances, its Notes, and its Commitments); provided, however, that (i) each such assignment shall be to an Eligible Assignee; (ii) except in the case of an assignment to another Lender or
an assignment of all of a Lender’s rights and obligations under this Agreement, any such partial assignment with respect to the Revolving Commitments shall be in an amount at least equal to $5,000,000.00 and any such partial assignment with
respect to the Term Loan shall be in an amount at least equal to $5,000,000; (iii) each assignment of a Lender’s rights and obligations with respect to Revolving Advances and its Revolving Commitment shall be of an constant, and not
varying percentage of all of its rights and obligations under this Agreement as a Revolving Lender and the Revolving Notes (other than rights of reimbursement and indemnity arising before the effective date of such assignment) and shall be of an
equal pro rata share of the Assignor’s interest in the Revolving Advances and Revolving Commitments; (iv) each assignment of a Lender’s rights and obligations with respect to Term Advances and its Term Commitment shall be of an
constant, and not varying percentage of all of its rights and obligations under this Agreement as a Term Lender and the Term Notes (other than rights of reimbursement and indemnity arising before the effective date of such assignment) and shall be
of an equal pro rata share of the Assignor’s interest in the Term Advances and Term Commitments; and (v) the parties to such assignment shall execute and deliver to the Administrative Agent for its acceptance an Assignment and Acceptance,
together with any Notes subject to such assignment and the assignor or assignee Lender shall pay a processing fee of $3,500.00; provided that such processing fee shall not be required for the initial assignments made by Wells Fargo as a Lender in
connection with the initial syndication of its Commitments hereunder. Upon execution, delivery, and acceptance of such Assignment and Acceptance and payment of the processing fee, the assignee thereunder shall be a party hereto and, to the extent of
such assignment, have the obligations, rights, and benefits of a Lender hereunder and the assigning Lender shall, to the extent of such assignment, relinquish its rights and be released from its obligations under this Agreement. Upon the
consummation of any assignment pursuant to this Section 9.7, the assignor, the Administrative Agent and the Borrower shall make appropriate arrangements so that, if required, new Notes are issued to the assignor and the assignee. If the
assignee is not incorporated under the laws of the United States of America or a state thereof, it shall deliver to the Borrower and the Administrative Agent certification as to exemption from deduction or withholding of Taxes in accordance with
Section 2.13(e). 
 (b) The Administrative Agent shall maintain at its address referred to in Section 9.9 a copy of
each Assignment and Acceptance delivered to and accepted by it and a register for the recordation of the names and addresses of the Lenders and the Commitments of, and principal amount of the Advances owing to, each Lender from time to time (the
“Register”). The entries in the Register shall be conclusive and binding for all purposes, absent manifest error, and the Credit Parties, the Administrative Agent and the Lenders may treat each Person whose name is recorded in the Register
as a Lender hereunder for all purposes of this Agreement. 
  

 -86- 

 (c) Upon its receipt of an Assignment and Acceptance executed by the parties thereto,
together with any Notes subject to such assignment and payment of the processing fee, the Administrative Agent shall, if such Assignment and Acceptance has been completed, (i) accept such Assignment and Acceptance, (ii) record the
information contained therein in the Register, and (iii) give prompt notice thereof to the parties thereto. 
 (d) Each
Lender may sell participations to one or more Persons in all or a portion of its rights, obligations or rights and obligations under this Agreement (including all or a portion of its Commitments or its Advances) provided, however, that
(i) such Lender’s obligations under this Agreement shall remain unchanged, (ii) such Lender shall remain solely responsible to the other parties hereto for the performance of such obligations, (iii) the participant shall be
entitled to the benefit of the yield protection provisions contained in Sections 2.10 and 2.11 and the right of set-off contained in Section 7.4, and (iv) the Borrower shall continue to deal solely and directly with such Lender in
connection with such Lender’s rights and obligations under this Agreement, and such Lender shall retain the sole right to enforce the obligations of the Borrower relating to its Advances and its Notes and to approve any amendment, modification,
or waiver of any provision of this Agreement (other than amendments, modifications, or waivers decreasing the amount of principal of or the rate at which interest is payable on such Advances or Notes, extending any scheduled principal payment date
or date fixed for the payment of interest on such Advances or Notes, or extending its Commitment). 
 (e) Notwithstanding any
other provision set forth in this Agreement, any Lender may at any time assign and pledge all or any portion of its Advances and its Notes to any Federal Reserve Bank as collateral security pursuant to Regulation A and any Operating Circular issued
by such Federal Reserve Bank. No such assignment shall release the assigning Lender from its obligations hereunder. 
 (f) Any
Lender may furnish any information concerning the Borrower or any of its Subsidiaries in the possession of such Lender from time to time to assignees and participants (including prospective assignees and participants), subject, however, to the
provisions of the following paragraph Section 9.8. 
 Section 9.8 Confidentiality. The Administrative Agent, the
Swing Line Lender, the Issuing Lender, and each Lender (each a “Lending Party”) agree to keep confidential any information furnished or made available to it by the Borrower pursuant to this Agreement; provided that nothing
herein shall prevent any Lending Party from disclosing such information (a) to any other Lending Party or any Affiliate of any Lending Party, or any officer, director, employee, agent, or advisor of any Lending Party or Affiliate of any Lending
Party for purposes of evaluating the transactions contemplated hereby, (b) to any other Person if directly incidental to the administration of the credit facility provided herein, (c) as required by any law, rule, or regulation,
(d) upon the order of any court or administrative agency, (e) upon the request or demand of any regulatory agency or authority, (f) that is or becomes available to the public or that is or becomes available to any Lending Party other
than as a result of a disclosure by any Lending Party prohibited by this Agreement, (g) in connection with any litigation relating to this Agreement or any other Credit Document to which such Lending Party or any of its Affiliates may be a
party, (h) to the extent necessary in connection with the exercise of any remedy under this Agreement or any other Credit Document, and (i) to any actual or proposed participant or assignee, in each case, subject to provisions
substantially similar to those contained in this Section 9.7. NOTWITHSTANDING ANYTHING TO THE CONTRARY CONTAINED HEREIN, nothing in this Agreement shall (a) restrict the Administrative Agent, the Issuing

  

 -87- 

 
Lender or any Lender from providing information to any bank or other regulatory or governmental authorities, including the Board and its supervisory staff; (b) require or permit the
Administrative Agent, the Issuing Lender or any Lender to disclose to the Borrower that any information will be or was provided to the Board or any of its supervisory staff; or (c) require or permit the Administrative Agent, the Issuing Lender
or any Lender to inform the Borrower of a current or upcoming Board examination or any nonpublic Board supervisory initiative or action. 
 Section 9.9 Notices, Etc. All notices and other communications (other than Notices of Borrowing and Notices of Continuation or Conversion, which are governed by Article 2 of this Agreement) shall
be in writing and hand delivered with written receipt, telecopied, sent by facsimile (with a hard copy sent as otherwise permitted in this Section 9.9), sent by a nationally recognized overnight courier, or sent by certified mail, return
receipt requested as follows: if to the Borrower or a Guarantor, as specified on Schedule II and if to any Lender, the Swing Line Lender, or the Issuing Lender, at its credit contact specified under its name on Schedule II. Each party may change its
notice address by written notification to the other parties. All such notices and communications shall be effective when delivered, except that notices and communications to any Lender, Swing Line Lender, or the Issuing Lender pursuant to
Article 2 shall not be effective until received and, in the case of telecopy, such receipt is confirmed by such Lender, Swing Line Lender or Issuing Lender, as applicable, verbally or in writing. 
 Section 9.10 Business Loans. The Borrower warrants and represents that the Obligations evidenced by the Notes are and shall be for
business, commercial, investment or other similar purposes and not primarily for personal, family, household or agricultural use, as such terms are used in Chapter One (“Chapter One”) of the Texas Credit Code. At all such times, if any, as
Chapter One shall establish a Maximum Rate, the Maximum Rate shall be the “indicated rate ceiling” (as such term is defined in Chapter One) from time to time in effect. 
 Section 9.11 Usury Not Intended. It is the intent of the Borrower and each Lender in the execution and performance of this Agreement
and the other Credit Documents to contract in strict compliance with applicable usury laws, including conflicts of law concepts, governing the Advances of each Lender including such applicable laws of the State of Texas, if any, and the United
States of America from time to time in effect. In furtherance thereof, the Lenders and the Borrower stipulate and agree that none of the terms and provisions contained in this Agreement or the other Credit Documents shall ever be construed to create
a contract to pay, as consideration for the use, forbearance or detention of money, interest at a rate in excess of the Maximum Rate and that for purposes of this Agreement “interest” shall include the aggregate of all charges which
constitute interest under such laws that are contracted for, charged or received under this Agreement; and in the event that, notwithstanding the foregoing, under any circumstances the aggregate amounts taken, reserved, charged, received or paid on
the Advances, include amounts which by applicable law are deemed interest which would exceed the Maximum Rate, then such excess shall be deemed to be a mistake and each Lender receiving same shall credit the same on the principal of its Notes (or if
such Notes shall have been paid in full, refund said excess to the Borrower). In the event that the maturity of the Notes are accelerated by reason of any election of the holder thereof resulting from any Event of Default under this Agreement or
otherwise, or in the event of any required or permitted prepayment, then such consideration that constitutes interest may never include more than the Maximum Rate, and

  

 -88- 

 
excess interest, if any, provided for in this Agreement or otherwise shall be canceled automatically as of the date of such acceleration or prepayment and, if theretofore paid, shall be credited
on the applicable Notes (or, if the applicable Notes shall have been paid in full, refunded to the Borrower of such interest). In determining whether or not the interest paid or payable under any specific contingencies exceeds the Maximum Rate, the
Borrower and the Lenders shall to the maximum extent permitted under applicable law amortize, prorate, allocate and spread in equal parts during the period of the full stated term of the Notes all amounts considered to be interest under applicable
law at any time contracted for, charged, received or reserved in connection with the Obligations. The provisions of this Section shall control over all other provisions of this Agreement or the other Credit Documents which may be in apparent
conflict herewith. 
 Section 9.12 Usury Recapture. In the event the rate of interest chargeable under this Agreement at
any time is greater than the Maximum Rate, the unpaid principal amount of the Advances shall bear interest at the Maximum Rate until the total amount of interest paid or accrued on the Advances equals the amount of interest which would have been
paid or accrued on the Advances if the stated rates of interest set forth in this Agreement had at all times been in effect. In the event, upon payment in full of the Advances, the total amount of interest paid or accrued under the terms of this
Agreement and the Advances is less than the total amount of interest which would have been paid or accrued if the rates of interest set forth in this Agreement had, at all times, been in effect, then the Borrower shall, to the extent permitted by
applicable law, pay the Administrative Agent for the account of the Lenders an amount equal to the difference between (i) the lesser of (A) the amount of interest which would have been charged on its Advances if the Maximum Rate had, at
all times, been in effect and (B) the amount of interest which would have accrued on its Advances if the rates of interest set forth in this Agreement had at all times been in effect and (ii) the amount of interest actually paid under this
Agreement on its Advances. In the event the Lenders ever receive, collect or apply as interest any sum in excess of the Maximum Rate, such excess amount shall, to the extent permitted by law, be applied to the reduction of the principal balance of
the Advances, and if no such principal is then outstanding, such excess or part thereof remaining shall be paid to the Borrower. 
 Section 9.13 Governing Law; Submission to Jurisdiction. This Agreement, the Notes and the other Credit Documents (unless otherwise expressly provided therein) shall be governed by, and construed and enforced in accordance with, the
laws of the State of Texas. Without limiting the intent of the parties set forth above, (a) Chapter 346 of the Texas Finance Code, as amended (relating to revolving loans and revolving tri-party accounts (formerly Tex. Rev. Civ. Stat. Ann. Art.
5069, Ch. 15)), shall not apply to this Agreement, the Notes, or the transactions contemplated hereby and (b) to the extent that any Lender may be subject to Texas law limiting the amount of interest payable for its account, such Lender shall
utilize the indicated (weekly) rate ceiling from time to time in effect. Each Letter of Credit shall be governed by the Uniform Customs and Practice for Documentary Credits, International Chamber of Commerce Publication No. 500 (1993 version). The
Borrower hereby irrevocably submits to the jurisdiction of any Texas state or federal court sitting in Houston, Texas in any action or proceeding arising out of or relating to this Agreement or the other Credit Documents, and the Borrower hereby
irrevocably agrees that all claims in respect of such action or proceeding may be heard and determined in such court. The Borrower hereby unconditionally and irrevocably waives, to the fullest extent it may effectively do so, any right it may have
to the defense of an inconvenient

  

 -89- 

 
forum to the maintenance of such action or proceeding. The Borrower hereby agrees that service of copies of the summons and complaint and any other process which may be served in any such action
or proceeding may be made by mailing or delivering a copy of such process to such Borrower at its address set forth in this Agreement. The Borrower agrees that a final judgment in any such action or proceeding shall be conclusive and may be enforced
in other jurisdictions by suit on the judgment or in any other manner provided by law. Nothing in this Section shall affect the rights of any Lender to serve legal process in any other manner permitted by the law or affect the right of any Lender to
bring any action or proceeding against the Borrower or its Property in the courts of any other jurisdiction. 
 Section 9.14
Execution in Counterparts. This Agreement may be executed in any number of counterparts and by different parties hereto in separate counterparts, each of which when so executed shall be deemed to be an original and all of which taken together
shall constitute one and the same agreement. 
 Section 9.15 Waiver of Jury. THE BORROWER, THE LENDERS, THE
ADMINISTRATIVE AGENT, THE ISSUING LENDER, AND THE SWING LINE LENDER HEREBY IRREVOCABLY WAIVE ANY AND ALL RIGHT TO TRIAL BY JURY IN RESPECT OF ANY LEGAL PROCEEDING ARISING OUT OF OR RELATING TO THIS AGREEMENT, ANY OTHER CREDIT DOCUMENT, OR ANY OF THE
TRANSACTIONS CONTEMPLATED HEREBY. 
 Section 9.16 USA Patriot Act. Each Lender that is subject to the Patriot Act and the
Administrative Agent (for itself and not on behalf of any Lender) hereby notifies 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 or the Administrative Agent, as applicable, to identify the Borrower in accordance with the Patriot Act. 
 PURSUANT TO SECTION 26.02 OF THE TEXAS BUSINESS AND COMMERCE CODE, A LOAN AGREEMENT IN WHICH THE AMOUNT INVOLVED IN THE LOAN
AGREEMENT EXCEEDS $50,000.00 IN VALUE IS NOT ENFORCEABLE UNLESS THE LOAN AGREEMENT IS IN WRITING AND SIGNED BY THE PARTY TO BE BOUND OR THAT PARTY’S AUTHORIZED REPRESENTATIVE. 
 THE RIGHTS AND OBLIGATIONS OF THE PARTIES TO AN AGREEMENT SUBJECT TO THE PRECEDING PARAGRAPH SHALL BE DETERMINED SOLELY FROM THE WRITTEN
LOAN AGREEMENT, AND ANY PRIOR ORAL AGREEMENTS BETWEEN THE PARTIES ARE SUPERSEDED BY AND MERGED INTO THE LOAN AGREEMENT. THIS WRITTEN AGREEMENT AND THE CREDIT DOCUMENTS, AS DEFINED IN THIS AGREEMENT, REPRESENT THE FINAL AGREEMENT AMONG THE PARTIES
WITH RESPECT TO THE SUBJECT MATTERS SET FORTH HEREIN AND MAY NOT BE CONTRADICTED BY EVIDENCE OF PRIOR, CONTEMPORANEOUS, OR SUBSEQUENT ORAL AGREEMENTS OF THE PARTIES.

Agreement) to the Borrower or any of its Subsidiaries (together with the Administrative Agent, the Issuing Lender and the Lenders, individually a “Beneficiary”, and collectively, the “Beneficiaries”). 
 INTRODUCTION 
 A. This Guaranty is given in connection with that certain Credit Agreement dated as of March 31, 2008 (as it has been or may be amended or otherwise modified from time to time, the “Credit Agreement”) among Flotek
Industries, Inc., a Delaware corporation (the “Borrower”), the lenders party thereto from time to time, (the “Lenders”) and Wells Fargo Bank, N.A., as an administrative agent (in such capacity, the
“Administrative Agent”), , as the issuing lender (in such capacity, the “Issuing Lender”) and as the swing line lender (in such capacity, the “Swing Line Lender”). 
 B. Each Guarantor is a Subsidiary of the Borrower and will derive substantial direct and indirect benefit from (i) the transactions
contemplated by the Credit Agreement and the other Credit Documents (as defined in the Credit Agreement), (ii) the Hedging Arrangements (as defined in the Credit Agreement) entered into by the Borrower or any of its other Subsidiaries with a
Lender or an Affiliate of a Lender (such counterparty being referred to as a “Swap Counterparty”), and (iii) the Banking Services (as defined in the Credit Agreement) provided by Wells Fargo Bank, N.A. or any of its Affiliates
to the Borrower and its Subsidiaries. 
 C. Each Guarantor is executing and delivering this Guaranty (i) to induce the
Lenders to provide and to continue to provide Advances under the Credit Agreement, (ii) to induce the Issuing Lender to provide and to continue to provide Letters of Credit under the Credit Agreement, and (iii) intending it to be a legal,
valid, binding, enforceable and continuing obligation of such Guarantor. 
 NOW, THEREFORE, in consideration of the premises,
the Guarantors and the Administrative Agent for the benefit of the Beneficiaries, do hereby further agree as follows: 
 Section
1. Definitions. All capitalized terms not otherwise defined in this Guaranty that are defined in the Credit Agreement shall have the meanings assigned to such terms by the Credit Agreement. 
 Section 2. Guaranty. 
 (a) Each Guarantor hereby absolutely, unconditionally and irrevocably guarantees the punctual payment and performance, when due, whether at stated maturity, by acceleration or otherwise, of all Secured
Obligations (including all Obligations, Banking Service

  

 Exhibit D 
 Page 1 of 14 

 
Obligations and obligations owing to Swap Counterparties), whether absolute or contingent and whether for principal, interest (including, without limitation, interest that but for the existence
of a bankruptcy, reorganization or similar proceeding would accrue), fees, amounts owing in respect of Letter of Credit Obligations, amounts required to be provided as collateral, indemnities, expenses or otherwise (collectively, the
“Guaranteed Obligations”). Without limiting the generality of the foregoing, each Guarantor’s liability shall extend to all amounts that constitute part of the Guaranteed Obligations and would be owed by the Borrower to the
Administrative Agent, the Issuing Lender, the Swing Line Lender or any Lender under the Credit Documents and by the Borrower to the Swap Counterparty but for the fact that they are unenforceable or not allowable due to insolvency or the existence of
a bankruptcy, reorganization or similar proceeding involving the Borrower. 
 (b) It is the intention of the Guarantors and each
Beneficiary that the amount of the Guaranteed Obligations guaranteed by each Guarantor shall be in, but not in excess of, the maximum amount permitted by fraudulent conveyance, fraudulent transfer and similar Legal Requirement applicable to such
Guarantor. Accordingly, notwithstanding anything to the contrary contained in this Guaranty or in any other agreement or instrument executed in connection with the payment of any of the Guaranteed Obligations, the amount of the Guaranteed
Obligations guaranteed by a Guarantor under this Guaranty shall be limited to an aggregate amount equal to the largest amount that would not render such Guarantor’s obligations hereunder subject to avoidance under Section 548 of the United
States Bankruptcy Code or any comparable provision of any other applicable law. 
 Section 3. Guaranty Absolute. Each
Guarantor guarantees that the Guaranteed Obligations will be paid strictly in accordance with the terms of the Credit Documents, regardless of any law, regulation or order now or hereafter in effect in any jurisdiction affecting any of such terms or
the rights of the Administrative Agent, the Issuing Lender, the Swing Line Lender, any Lender or any Swap Counterparty with respect thereto but subject to Section 2(b) above. The obligations of each Guarantor under this Guaranty are independent
of the Guaranteed Obligations or any other obligations of any other Person under the Credit Documents or in connection with any Hedging Arrangement, and a separate action or actions may be brought and prosecuted against a Guarantor to enforce this
Guaranty, irrespective of whether any action is brought against the Borrower, any other Guarantor or any other Person or whether the Borrower, any other Guarantor or any other Person is joined in any such action or actions. The liability of each
Guarantor under this Guaranty shall be irrevocable, absolute and unconditional irrespective of, and each Guarantor hereby irrevocably waives any defenses it may now or hereafter have in any way relating to, any or all of the following: 

(a) any lack of validity or enforceability of any Credit Document or any agreement or instrument relating thereto or any part of the
Guaranteed Obligations being irrecoverable; 
 (b) any change in the time, manner or place of payment of, or in any other term
of, all or any of the Guaranteed Obligations or any other obligations of any Person under the Credit Documents or any agreement or instrument relating to Hedging Arrangements with a Swap Counterparty, or any other amendment or waiver of or any
consent to departure from any Credit Document or any agreement or instrument relating to Hedging Arrangements with a Swap Counterparty, including, without limitation, any increase in the Guaranteed Obligations resulting from the extension of
additional credit to the Borrower or otherwise; 
  

 Exhibit D 
 Page 2 of 14 

 (c) any taking, exchange, release or non-perfection of any collateral, or any taking,
release or amendment or waiver of or consent to departure from any other guaranty, for all or any of the Guaranteed Obligations; 
 (d) any manner of application of collateral, or proceeds thereof, to all or any of the Guaranteed Obligations, or any manner of sale or other disposition of any collateral for all or any of the Guaranteed Obligations or any other
obligations of any other Person under the Credit Documents or any other assets of the Borrower or any of its Subsidiaries; 
 (e) any change, restructuring or termination of the corporate structure or existence of the Borrower or any of its Subsidiaries; 
 (f) any failure of any Lender, the Administrative Agent, the Issuing Lender, the Swing Line Lender or any other Beneficiary to disclose to the Borrower or any Guarantor any information relating to the
business, condition (financial or otherwise), operations, properties or prospects of any Person now or in the future known to the Administrative Agent, the Issuing Lender, the Swing Line Lender, any Lender or any other Beneficiary (and each
Guarantor hereby irrevocably waives any duty on the part of any Beneficiary to disclose such information); 
 (g) any signature
of any officer of the Borrower being mechanically reproduced in facsimile or otherwise; or 
 (h) any other circumstance or any
existence of or reliance on any representation by any Beneficiary that might otherwise constitute a defense available to, or a discharge of, the Borrower, any Guarantor or any other guarantor, surety or other Person. 
 Section 4. Continuation and Reinstatement, Etc. Each Guarantor agrees that, to the extent that payments of any of the Guaranteed
Obligations are made, or any Lender, the Administrative Agent, the Issuing Lender, the Swing Line Lender or any Swap Counterparty receives any proceeds of collateral, and such payments or proceeds or any part thereof are subsequently invalidated,
declared to be fraudulent or preferential, set aside, or otherwise required to be repaid, then to the extent of such repayment the Guaranteed Obligations shall be reinstated and continued in full force and effect as of the date such initial payment
or collection of proceeds occurred. EACH GUARANTOR SHALL DEFEND AND INDEMNIFY EACH BENEFICIARY FROM AND AGAINST ANY CLAIM, DAMAGE, LOSS, LIABILITY, COST, OR EXPENSE UNDER THIS SECTION 4 (INCLUDING REASONABLE ATTORNEYS’ FEES AND EXPENSES) IN
THE DEFENSE OF ANY SUCH ACTION OR SUIT, INCLUDING SUCH CLAIM, DAMAGE, LOSS, LIABILITY, COST, OR EXPENSE ARISING AS A RESULT OF THE INDEMNIFIED BENEFICIARY’S OWN NEGLIGENCE BUT EXCLUDING SUCH CLAIM, DAMAGE, LOSS, LIABILITY, COST, OR EXPENSE THAT
IS FOUND IN A FINAL, NON-APPEALABLE JUDGMENT BY A COURT OF COMPETENT JURISDICTION TO HAVE RESULTED FROM SUCH INDEMNIFIED BENEFICIARY’S GROSS NEGLIGENCE, WILLFUL MISCONDUCT, OR BAD FAITH.

 Section 5. Waivers and Acknowledgments. 
 (a) Each Guarantor hereby waives promptness, diligence, presentment, notice of acceptance and any other notice with respect to any of the
Guaranteed Obligations and this Guaranty and any requirement that any Beneficiary protect, secure, perfect or insure any Lien or any property or exhaust any right or take any action against the Borrower or any other Person or any collateral.

 (b) Each Guarantor hereby irrevocably waives any right to revoke this Guaranty, and acknowledges that this Guaranty is
continuing in nature and applies to all Guaranteed Obligations, whether existing now or in the future. 
 (c) Each Guarantor
acknowledges that it will receive substantial direct and indirect benefits from the financing arrangements involving the Borrower or any Subsidiary of the Borrower contemplated by the Credit Documents and the Hedging Arrangements and that the
waivers set forth in this Guaranty are knowingly made in contemplation of such benefits. 
 Section 6. Subrogation and
Subordination. 
 (a) No Guarantor will exercise any rights that it may now have or hereafter acquire against the Borrower
or any other Person to the extent that such rights arise from the existence, payment, performance or enforcement of such Guarantor’s obligations under this Guaranty or any other Credit Document, including, without limitation, any right of
subrogation, reimbursement, exoneration, contribution or indemnification and any right to participate in any claim or remedy of any Beneficiary against the Borrower or any other Person, whether or not such claim, remedy or right arises in equity or
under contract, statute or common law, including, without limitation, the right to take or receive from the Borrower or any other Person, directly or indirectly, in cash or other property or by set-off or in any other manner, payment or security on
account of such claim, remedy or right, unless and until all of the Guaranteed Obligations and any and all other amounts payable by the Guarantors under this Guaranty shall have been paid in full in cash and no Letter of Credit Obligations shall
remain outstanding and all Commitments shall have expired or terminated. If any amount shall be paid to a Guarantor in violation of the preceding sentence at any time prior to (a) the payment in full in cash of the Guaranteed Obligations and
any and all other amounts payable by the Guarantors under this Guaranty, (b) the satisfaction of all Letter of Credit Obligations and the termination of all obligations of the Issuing Lender and the Lenders in respect of Letters of Credit, and
(c) the termination of the Commitments, such amount shall be held in trust for the benefit of the Beneficiaries and shall forthwith be paid to the Administrative Agent to be credited and applied to the Guaranteed Obligations and any and all
other amounts payable by the Guarantors under this Guaranty, whether matured or unmatured, in accordance with the terms of the Credit Documents. 
 (b) Each Guarantor and the Borrower agrees that all Subordinated Guarantor Obligations (as hereinafter defined) are and shall be subordinate and inferior in rank, preference and priority to all
obligations of such Guarantor in respect of the Guaranteed Obligations hereunder, and the Borrower and such Guarantor shall, if requested by the Administrative Agent, execute a subordination agreement reasonably satisfactory to the Administrative
Agent to more fully set out the terms of such subordination. Each Guarantor and the Borrower agrees that none

 Page 4 of 14 

 
of the Subordinated Guarantor Obligations shall be secured by a lien or security interest on any assets of such Guarantor or any ownership interests in any Subsidiary of such Guarantor.

including, without limitation, all future advances, with interest, attorneys’ fees, expenses of collection and costs.

There are no conditions precedent to the effectiveness of this Guaranty. Such Guarantor benefits from executing this Guaranty.

Guaranty, and such Guarantor has established adequate means of obtaining from the Borrower and each other relevant Person on a continuing basis information pertaining to, and is now and on a continuing basis will be completely familiar with, the
business, condition (financial and otherwise), operations, properties and prospects of the Borrower and each other relevant Person. 
 (c) The obligations of such Guarantor under this Guaranty are the valid, binding and legally enforceable obligations of such Guarantor, (except as limited by (i) applicable bankruptcy, insolvency, reorganization, moratorium, or similar
laws at the time in effect affecting the rights of creditors generally and (ii) general principles of equity whether applied by a court of law or equity), and the execution and delivery of this Guaranty by such Guarantor has been duly and
validly authorized in all respects by all requisite corporate, limited liability company or partnership actions on the part of such Guarantor, and the Person who is executing and delivering this Guaranty on behalf of such Guarantor has full power,
authority and legal right to so do, and to observe and perform all of the terms and conditions of this Guaranty on such Guarantor’s part to be observed or performed.

Beneficiary is hereby authorized at any time, to the fullest extent permitted by law, to set-off and apply any deposits (general or special, time or demand, provisional or final) and other indebtedness owing by such Beneficiary to the account of
each Guarantor against any and all of the obligations of the Guarantors under this Guaranty, irrespective of whether or not such Beneficiary shall have made any demand under this Guaranty and although such obligations may be contingent and
unmatured. Such Beneficiary shall promptly notify the affected Guarantor after any such set-off and application is made, provided that the failure to give such notice shall not affect the validity of such set-off and application. The rights of the
Beneficiaries under this Section 8 are in addition to other rights and remedies (including, without limitation, other rights of set-off) which any Beneficiary may have.

communications to the Administrative Agent shall not be effective until received by the Administrative Agent. 
 Section 11.
No Waiver: Remedies. No failure on the part of the Administrative Agent or any other Beneficiary to exercise, and no delay in exercising, any right hereunder shall operate as a waiver thereof; nor shall any single or partial exercise of any
right hereunder preclude any other or further exercise thereof or the exercise of any other right. The remedies herein provided are cumulative and not exclusive of any remedies provided by law.

its Commitment, the Advances owing to it and the Note or Notes held by it) to any other Person, and such other Person shall thereupon become vested with all the benefits in respect thereof granted to such Lender herein or otherwise, subject,

the Guaranty Agreement). 
 A. Reference is made to the Credit Agreement dated as of March 31, 2008 (as amended, restated,

Administrative Agent, as issuing lender (the “Issuing Lender”) and as swing line lender. 
 B. Capitalized terms used
herein and not otherwise defined herein shall have the meanings assigned to such terms in the Guaranty Agreement and the Credit Agreement. 
 C. The Guarantors have entered into the Guaranty Agreement in order to induce the Lenders to make Advances and the Issuing Lender to issue Letters of Credit. Section 16 of the Guaranty Agreement
provides that additional Subsidiaries of the Borrower may become Guarantors under the Guaranty Agreement by execution and delivery of an instrument in the form of this Supplement. The undersigned Subsidiary of the Borrower (the “New
Guarantor”) is executing this Supplement in accordance with the requirements of the Credit Agreement to become a Guarantor under the Guaranty Agreement in order to induce the Lenders to make additional Advances and the Issuing Lender to
issue additional Letters of Credit and as consideration for Advances previously made and Letters of Credit previously issued. 
 Accordingly, the Administrative Agent and the New Guarantor agree as follows: 
 SECTION 1. In accordance with
Section 16 of the Guaranty Agreement, the New Guarantor by its signature below becomes a Guarantor under the Guaranty Agreement with the same force and effect as if originally named therein as a Guarantor and the New Guarantor hereby
(a) agrees to all the terms and provisions of the Guaranty Agreement applicable to it as a Guarantor thereunder and (b) represents and warrants that the representations and warranties made by it as a Guarantor thereunder are true and
correct in all material respects on and as of the date hereof. Each reference to a “Guarantor” in the Guaranty Agreement shall be deemed to include the New Guarantor. The Guaranty Agreement is hereby incorporated herein by reference.

 SECTION 2. The New Guarantor represents and warrants to the Administrative Agent and the other Beneficiaries that this
Supplement has been duly authorized, executed and delivered by it by all requisite corporate limited liability company or partnership action and constitutes its legal, valid and binding obligation, enforceable against it in accordance with its terms
(subject to applicable bankruptcy, reorganization, insolvency, moratorium or similar laws affecting creditors’ rights generally and subject, as to enforceability, to equitable principles of general application (regardless of whether enforcement
is sought in a proceeding in equity or at law)). 
  

 Exhibit D 
 Page 12 of 14 

 SECTION 3. This Supplement may be executed in counterparts, each of which shall constitute
an original, but all of which when taken together shall constitute a single contract. This Supplement shall become effective when the Administrative Agent shall have received counterparts of this Supplement that, when taken together, bear the
signatures of the New Guarantor and the Administrative Agent. Delivery of an executed signature page to this Supplement by fax transmission shall be as effective as delivery of a manually executed counterpart of this Supplement. 
 SECTION 4. Except as expressly supplemented hereby, the Guaranty Agreement shall remain in full force and effect. 
 SECTION 5. THIS SUPPLEMENT SHALL BE GOVERNED BY, AND CONSTRUED AND ENFORCED IN ACCORDANCE WITH, THE LAWS OF THE STATE OF TEXAS. The New
Guarantor hereby irrevocably submits to the jurisdiction of any Texas state or federal court sitting in Houston, Texas in any action or proceeding arising out of or relating to this Supplement or the Guaranty and the other Credit Documents, and the
New Guarantor hereby irrevocably agrees that all claims in respect of such action or proceeding may be heard and determined in such court. The New Guarantor hereby irrevocably waives, to the fullest extent it may effectively do so, any right it may
have to the defense of an inconvenient forum to the maintenance of such action or proceeding. The New Guarantor hereby agrees that service of copies of the summons and complaint and any other process which may be served in any such action or
proceeding may be made by mailing or delivering a copy of such process to such Guarantor at its address set forth on the signature page hereof. The New Guarantor agrees that a final judgment in any such action or proceeding shall be conclusive and
may be enforced in other jurisdictions by suit on the judgment or in any other manner provided by law. Nothing in this Section shall affect the rights of any Beneficiary to serve legal process in any other manner permitted by the law or affect the
right of any Beneficiary to bring any action or proceeding against the New Guarantor or its Property in the courts of any other jurisdiction. 
 SECTION 6. In case any one or more of the provisions contained in this Supplement should be held invalid, illegal or unenforceable in any respect, the validity, legality and enforceability of the
remaining provisions contained herein and in the Guaranty Agreement shall not in any way be affected or impaired thereby (it being understood that the invalidity of a particular provision hereof in a particular jurisdiction shall not in and of
itself affect the validity of such provision in any other jurisdiction). The parties hereto shall endeavor in good-faith negotiations to replace the invalid, illegal or unenforceable provisions with valid provisions the economic effect of which
comes as close as possible to that of the invalid, illegal or unenforceable provisions. 
 SECTION 7. All communications and
notices hereunder shall be in writing and given as provided in Section 10 of the Guaranty Agreement.

right or remedy against any other guarantor of, or collateral securing, any Secured Obligations, (c) any change in the time, manner or place of payment of, or in any other term of, all or

termination whatsoever by reason of the invalidity, illegality, nongenuineness, irregularity, compromise, unenforceability of, or any other event or occurrence affecting, any Secured Obligations or otherwise, (e) any amendment to, rescission,
waiver, or other modification of, or any consent to or departure from, any of the terms of any Credit Document, (f) any addition, exchange or release of any Collateral of the Secured Obligations, or any surrender or non-perfection of any

indemnification, any right to participate in any claim or remedy of any Secured Party against any Obligor or any collateral which any Secured Party now has or hereafter acquires, whether or not such claim, remedy or right arises in equity, or under
contract, statute or common law, including the right to take or receive from any Obligor, directly or indirectly, in cash or other property or by set-off or in any manner, payment or security on account of such claim or other rights. If any amount
shall be paid to any Grantor in violation of the preceding sentence and the Secured Obligations shall not have been indefeasibly paid in full in cash or all Commitments and all other commitments by any Secured Party to any Obligor have not been
terminated or all Letters of Credit have not terminated or expired, then such amount shall be deemed to have been paid to such Grantor for the benefit of, and held in trust for, the Administrative Agent (on behalf of the Secured Parties), and shall

Agreement or the other Credit Documents giving any Secured Party a lien upon any Collateral, either by judicial foreclosure or by non-judicial sale or enforcement, such Secured Party may, at its sole option, determine which of its remedies or rights
it may pursue without affecting any of its rights and remedies under this Security Agreement. If, in the exercise of any of its rights and remedies, any Secured Party shall forfeit any of its rights or remedies, including its right to enter a
deficiency judgment against any Obligor or any other

  

 Exhibit G – Form of Pledge and Security Agreement

Person, whether because of any applicable laws pertaining to “election of remedies” or the like, each Grantor hereby consents to such action by such Secured Party and waives any claim
based upon such action, even if such action by such Secured Party shall result in a full or partial loss of any rights of subrogation that such Grantor might otherwise have had but for such action by such Secured Party.

(i) a Default has occurred and is continuing, (ii) the value of such Certificated Equipment is used in determining the OLV of Fixed Assets under the Credit Agreement or (iii) the aggregate value of Certificated Equipment as to which
the relevant certificates of title have not been endorsed and delivered to the Administrative Agent shall exceed $3,000,000, then such Grantor agrees to take such action (or cause its Subsidiaries to take such action), including endorsing
certificates of title or executing applications for transfer of title, as is reasonably required by the Administrative Agent to enable it to properly perfect and protect its Lien on such Certificated Equipment and to transfer the same.

(iii), such Grantor shall either (x) reasonably and in good faith determine that any of such Intellectual Property Collateral is of negligible economic value to such Grantor, or (y) the loss of the Intellectual Property Collateral
would not be reasonably likely to have a Material Adverse Effect on the business; 
 (b) such Grantor shall
promptly notify the Administrative Agent if it knows that any application or registration relating to any material item of the Intellectual Property Collateral may become abandoned or dedicated to the public or placed in the public domain or invalid
or unenforceable, or of any adverse determination or development (including the institution of, or any such determination or development in, any proceeding in the United States Patent and Trademark Office, the United States Copyright Office or any

request to evidence the Administrative Agent’s security interest in such Intellectual Property Collateral; 
 (d) such Grantor will take all necessary steps, including in any proceeding before the United States Patent and Trademark Office, the United States Copyright Office or (subject to the terms of the Credit Agreement) any similar office or

 (e) following the obtaining of an interest in any material Intellectual Property by such Grantor, such Grantor shall deliver a supplement to Schedule II identifying such new Intellectual Property; and 
 (f) following the obtaining of an interest in any material Intellectual Property by such Grantor or, following the occurrence
and during the continuance of an Event of Default, upon the request of the Administrative Agent, such Grantor shall deliver all agreements, instruments and documents the Administrative Agent may reasonably request to evidence the Administrative
Agent’s security interest in such Intellectual Property Collateral and as may otherwise be required to acknowledge or register or perfect the Administrative Agent’s interest in any part of such item of Intellectual Property Collateral
unless such Grantor shall determine in good faith (with the consent of the Administrative Agent) that any Intellectual Property Collateral is of negligible economic value to such Grantor. 
 SECTION 4.7. As to Letter-of-Credit Rights. 
 (a) Each Grantor, by granting a security interest in its Letter-of-Credit Rights to the Administrative Agent, intends to (and
hereby does) collaterally assign to the Administrative Agent its rights (including its contingent rights ) to the Proceeds of all Letter-of-Credit Rights of which it is or hereafter becomes a beneficiary or assignee. Promptly following the date on
which any Grantor obtains any Letter of Credit Rights after the date hereof, such Grantor shall (i) deliver a supplement to Schedule II identifying such new Letter-of-Credit Right and (ii) with respect to Letter of Credit Rights in
excess of $250,000 cause the issuer of each Letter of Credit and each nominated person (if any) with respect thereto to consent to such assignment of the Proceeds thereof in a consent agreement in form and substance reasonably satisfactory to the
Administrative Agent and deliver written evidence of such consent to the Administrative Agent. 
 (b) During the
existence of an Event of Default, each Grantor will, promptly upon request by the Administrative Agent, (i) notify (and each Grantor hereby authorizes the Administrative Agent to notify) the issuer and each nominated person with respect to each
of the Letters of Credit that the Proceeds thereof have been assigned to the Administrative Agent hereunder and any payments due or to become due in respect thereof are to be made directly to the Administrative Agent and (ii) arrange for the
Administrative Agent to become the transferee beneficiary Letter of Credit. 
 SECTION 4.8. As to Commercial Tort Claims.
Each Grantor covenants and agrees that, until the Termination Date, with respect to any Commercial Tort Claim in excess of $250,000 individually or in the aggregate hereafter arising, it shall deliver to the Administrative Agent a supplement to

 Page 22 of 49 

 SECTION 4.9. Electronic Chattel Paper and Transferable Records. If any Grantor at any
time holds or acquires an interest in any electronic chattel paper or any “transferable record,” as that term is defined in Section 201 of the U.S. Federal Electronic Signatures in Global and National Commerce Act, or in
Section 16 of the U.S. Uniform Electronic Transactions Act as in effect in any relevant jurisdiction, with a value in excess of $250,000, such Grantor shall promptly notify the Administrative Agent thereof and, at the request of the
Administrative Agent, shall take such action as the Administrative Agent may request to vest in the Administrative Agent control (for the ratable benefit of Secured Parties) under Section 9.105 of the U.C.C. of such electronic chattel paper or
control under Section 201 of the Federal Electronic Signatures in Global and National Commerce Act or, as the case may be, Section 16 of the Uniform Electronic Transactions Act, as so in effect in such jurisdiction, of such transferable
record. The Administrative Agent agrees with each Grantor that the Administrative Agent will arrange, pursuant to procedures reasonably satisfactory to the Administrative Agent and so long as such procedures will not result in the Administrative
Agent’s loss of control, for such Grantor to make alterations to the electronic chattel paper or transferable record permitted under Section 9.105 of the U.C.C. or, as the case may be, Section 201 of the U.S. Federal Electronic
Signatures in Global and National Commerce Act or Section 16 of the U.S. Uniform Electronic Transactions Act for a party in control to allow without loss of control, unless an Event of Default has occurred and is continuing or would occur after
taking into account any action by such Grantor with respect to such electronic chattel paper or transferable record. 
 SECTION
4.10. Transfers and Other Liens. No Grantor shall: (a) sell, assign (by operation of law or otherwise) or otherwise dispose of any of the Collateral, except Inventory in the ordinary course of business or as specifically permitted by the
Credit Agreement, or (b) create or suffer to exist any Lien or other charge or encumbrance upon or with respect to any of the Collateral to secure Debt of any Person or entity, except for the security interest created by this Security Agreement
and except for Liens and other charges or encumbrances specifically permitted by the Credit Agreement. 
 SECTION 4.11.
Taxes. Each Grantor agrees to comply in all material respects with all Applicable Law, including the appropriate payment (before the same become delinquent), by, or on behalf of, such Grantor of all Taxes imposed upon such Grantor or any of
its direct or indirect Subsidiaries or upon their property except to the extent being diligently contested in good faith by appropriate proceedings and for which adequate reserves in accordance with GAAP have been set aside on the books of such
Grantor or such Subsidiaries, as applicable. 
 SECTION 4.12. Further Assurances, etc. Each Grantor shall warrant and
defend the right and title herein granted unto the Administrative Agent in and to the Collateral (and all right, title and interest represented by the Collateral) against the claims and demands of all Persons whomsoever. Each Grantor agrees that,
from time to time at its own expense, it will promptly execute and deliver all further instruments and documents, and take all further action, that may be necessary or that the Administrative Agent may reasonably request, in order to perfect,
preserve and protect any security interest granted or purported to be granted hereby or to enable the Administrative Agent to exercise and enforce its rights and remedies hereunder with respect to any Collateral. Each Grantor agrees that, upon the
acquisition after the date hereof by such Grantor of any Collateral, with respect to which the security interest granted hereunder is not perfected automatically upon such acquisition, to take such actions with respect to such Collateral or any part
thereof as required by the Credit Documents. Without limiting the generality of the foregoing, each Grantor will: 
 (a) from time to time upon the request of the Administrative Agent, promptly deliver to the Administrative Agent such stock powers, instruments and similar documents, reasonably satisfactory in form and substance to the Administrative
Agent, with respect to such Collateral as the Administrative Agent may reasonably request and will, from time to time upon the request of the Administrative Agent, after the occurrence and during the continuance of any Event of Default, promptly
transfer any securities constituting Collateral into the name of any nominee designated by the Administrative Agent; if any Collateral shall be evidenced by an Instrument, negotiable Document, Promissory Note or tangible Chattel Paper, deliver and
pledge to the Administrative Agent hereunder such Instrument, negotiable Document, Promissory Note, Pledged Note or tangible Chattel Paper duly endorsed and accompanied by duly executed instruments of transfer or assignment, all in form and
substance reasonably satisfactory to the Administrative Agent; 
  

 Exhibit G – Form of Pledge and Security Agreement 
 Page 23 of 49 

 (b) file (and hereby authorize the Administrative Agent to file after
delivery of a copy thereof to such Grantor) such filing statements or continuation statements, or amendments thereto, and such other instruments or notices (including any assignment of claim form under or pursuant to the federal assignment of claims
statute, 31 U.S.C. § 3726, any successor or amended version thereof or any regulation promulgated under or pursuant to any version thereof), as may be necessary or that the Administrative Agent may request in order to perfect and preserve the
security interests and other rights granted or purported to be granted to the Administrative Agent hereby. The authorization contained in this Section 4.12 shall be irrevocable and continuing until the Termination Date; 
 (c) deliver to the Administrative Agent and at all times keep pledged to the Administrative Agent pursuant hereto, on a
first-priority, perfected basis, at the request of the Administrative Agent, all Investment Property constituting Collateral (except for Permitted Liens), all Distributions with respect thereto (which shall only be delivered to the Administrative
Agent during the continuance of a Default), and all interest and principal with respect to Promissory Notes, and all Proceeds and rights from time to time received by or distributable to such Grantor in respect of any of the foregoing Collateral;

 (d) not take or omit to take any action the taking or the omission of which would result in any impairment or
alteration of any obligation of the maker of any Payment Intangible or other Instrument constituting Collateral, except as provided in Section 4.4; 
 (e) not create any tangible Chattel Paper without placing a legend on such tangible Chattel Paper reasonably acceptable to

 (f) furnish to the Administrative Agent, from time to time at the
Administrative Agent’s request, statements and schedules further identifying and describing the Collateral and such other reports in connection with the Collateral as the Administrative Agent may reasonably request, all in reasonable detail;
and 
 (g) do all things reasonably requested by the Administrative Agent in accordance with this Security
Agreement in order to enable the Administrative Agent to have and maintain control over the Collateral consisting of Investment Property, Deposit Accounts, Letter-of-Credit-Rights and Electronic Chattel Paper. 
 Each Grantor agrees that a carbon, photographic or other reproduction of this Security Agreement or any UCC financing statement covering the Collateral or
any part thereof shall be sufficient as a UCC financing statement where permitted by law. Each Grantor hereby authorizes the Administrative Agent to file financing statements describing as the collateral covered thereby “all of the
debtor’s personal property or assets” or words to that effect, notwithstanding that such wording may be broader in scope than the Collateral described in this Security Agreement. 
 ARTICLE V 
 THE ADMINISTRATIVE AGENT 
 SECTION 5.1. Administrative Agent Appointed Attorney-in-Fact. Each Grantor hereby irrevocably appoints the Administrative Agent its
attorney-in-fact, with full authority in the place and stead of such Grantor and in the name of such Grantor or otherwise, from time to time in the Administrative Agent’s discretion, following the occurrence and during the continuance of an
Event of Default, to take any action and to execute any instrument which the Administrative Agent may deem necessary or advisable to accomplish the purposes of this Security Agreement, including (a) to ask, demand, collect, sue for, recover,
compromise, receive and give acquittance and receipts for moneys due and to become due under or in respect of any of the Collateral, (b) to receive, endorse, and collect any drafts or other Instruments, Documents and Chattel Paper, in
connection with clause (a) above, (c) to file any claims or take any action or institute any proceedings which the Administrative Agent may deem necessary or desirable for the collection of any of the Collateral or otherwise to
enforce the rights of the Administrative Agent with respect to any of the Collateral, and (d) to perform the affirmative obligations of such Grantor hereunder. EACH GRANTOR HEREBY ACKNOWLEDGES, CONSENTS AND AGREES THAT THE POWER OF ATTORNEY
GRANTED PURSUANT TO THIS SECTION 5.1 IS IRREVOCABLE AND COUPLED WITH AN INTEREST AND SHALL BE EFFECTIVE UNTIL THE TERMINATION DATE. 
 SECTION 5.2. Administrative Agent May Perform. If any Grantor fails to perform any agreement contained herein, the Administrative Agent may itself perform, or cause performance of, such agreement,
and the expenses of the Administrative Agent incurred in connection therewith shall be payable by such Grantor pursuant to Section 6.4 hereof and Section 9.1 of the Credit Agreement and the Administrative Agent may from time to time
take any other action which the Administrative Agent reasonably deems necessary for the maintenance, preservation or protection of any of the Collateral or of its security interest therein. 
  

 Exhibit G – Form of Pledge and Security Agreement 
 Page 25 of 49 

 SECTION 5.3. Administrative Agent Has No Duty. The powers conferred on the
Administrative Agent hereunder are solely to protect its interest (on behalf of the Secured Parties) in the Collateral and shall not impose any duty on it to exercise any such powers. Except for reasonable care of any Collateral in its possession
and the accounting for moneys actually received by it hereunder, the Administrative Agent shall have no duty as to any Collateral or responsibility for (a) ascertaining or taking action with respect to calls, conversions, exchanges, maturities,
tenders or other matters relative to any Investment Property and any other Pledged Property, whether or not the Administrative Agent has or is deemed to have knowledge of such matters, or (b) taking any necessary steps to preserve rights
against prior parties or any other rights pertaining to any Collateral. 
 SECTION 5.4. Reasonable Care. The
Administrative Agent is required to exercise reasonable care in the custody and preservation of any of the Collateral in its possession; provided, that the Administrative Agent shall be deemed to have exercised reasonable care in the custody
and preservation of any of the Collateral (a) if such Collateral is accorded treatment substantially equal to that which the Administrative Agent accords its own personal property, or (b) if the Administrative Agent takes such action for
that purpose as any Grantor reasonably requests in writing at times other than upon the occurrence and during the continuance of an Event of Default; provided, further, that failure of the Administrative Agent to comply with any such
request at any time shall not in itself be deemed a failure to exercise reasonable care. 
 ARTICLE VI 
 REMEDIES 
 SECTION
6.1. Certain Remedies. If any Event of Default shall have occurred and be continuing: 
 (a) The
Administrative Agent may exercise in respect of the Collateral, in addition to other rights and remedies provided for herein or otherwise available to it, all the rights and remedies of a secured party on default under the UCC (whether or not the
UCC applies to the affected Collateral) and also may (i) take possession of any Collateral not already in its possession without demand and without legal process, (ii) require any Grantor to, and each Grantor hereby agrees that it will, at
its expense and upon request of the Administrative Agent forthwith, assemble all or part of the Collateral as directed by the Administrative Agent and make it available to the Administrative Agent at a place to be designated by the Administrative
Agent that is reasonably convenient to both parties, (iii) subject to applicable law or agreements with landlords, enter onto the property where any Collateral is located and take possession thereof without demand and without legal process,
(iv) without notice except as specified below, lease, license, sell or otherwise dispose of the Collateral or any part thereof in one or more parcels at public or private sale, at any of the Administrative Agent’s offices or elsewhere, for
cash, on credit or for future delivery, and upon such other terms as the Administrative Agent may deem commercially reasonable. Each Grantor agrees that, to the extent notice of sale shall be required by law, at least ten (10) days’ prior
notice to the applicable Grantor of the time and place of any public sale or the time of any private sale is to be made shall constitute reasonable notification; provided, however, that with respect to Collateral that is (x)

  

 Exhibit G – Form of Pledge and Security Agreement 
 Page 26 of 49 

 
perishable or threatens to decline speedily in value, or (y) is of a type customarily sold on a recognized market (including but not limited to, Investment Property), no notice of sale or
disposition need be given. For purposes of this Article VI, notice of any intended sale or disposition of any Collateral may be given by first-class mail, hand-delivery (through a delivery service or otherwise), facsimile or email, and shall
be deemed to have been “sent” upon deposit in the U.S. Mails with adequate postage properly affixed, upon delivery to an express delivery service or upon electronic submission through telephonic or internet services, as applicable. The
Administrative Agent shall not be obligated to make any sale of Collateral regardless of notice of sale having been given. The Administrative Agent may adjourn any public or private sale from time to time by announcement at the time and place fixed
therefor, and such sale may, without further notice, be made at the time and place to which it was so adjourned. 
 (b) Each Grantor agrees and acknowledges that a commercially reasonable disposition of Inventory, Equipment, Goods, Computer Hardware and Software Collateral, or Intellectual Property may be by lease or license of, in addition to the sale
of, such Collateral. Each Grantor further agrees and acknowledges that the following shall be deemed a reasonable commercial disposition: (i) a disposition made in the usual manner on any recognized market, (ii) a disposition at the price
current in any recognized market at the time of disposition, and (iii) a disposition in conformity with reasonable commercial practices among dealers in the type of property subject to the disposition. 
 (c) All cash Proceeds received by the Administrative Agent in respect of any sale of, collection from, or other realization
upon, all or any part of the Collateral shall be applied by the Administrative Agent against, all or any part of the Obligations as set forth in Section 7.6 of the Credit Agreement. The Administrative Agent shall not be obligated to
apply or pay over for application noncash proceeds of collection or enforcement unless (i) the failure to do so would be commercially unreasonable, and (ii) the affected party has provided the Administrative Agent with a written demand to
apply or pay over such noncash proceeds on such basis. 
 (d) The Administrative Agent may do any or all of the
following: (i) transfer all or any part of the Collateral into the name of the Administrative Agent or its nominee, with or without disclosing that such Collateral is subject to the Lien hereunder, (ii) notify the parties obligated on any
of the Collateral to make payment to the Administrative Agent of any amount due or to become due thereunder, (iii) withdraw, or cause or direct the withdrawal, of all funds with respect to the Collateral Account, (iv) enforce collection of
any of the Collateral by suit or otherwise, and surrender, release or exchange all or any part thereof, or compromise or extend or renew for any period (whether or not longer than the original period) any obligations of any nature of any party with
respect thereto, (v) endorse any checks, drafts, or other writings in the applicable Grantor’s name to allow collection of the Collateral, (vi) take control of any Proceeds of the Collateral, or (vii) execute (in the name, place
and stead of the applicable Grantor) endorsements, assignments, stock powers and other instruments of conveyance or transfer with respect to all or any of the Collateral. 
  

 Exhibit G – Form of Pledge and Security Agreement 
 Page 27 of 49 

 SECTION 6.2. Securities Laws. If the Administrative Agent shall determine to exercise
its right to sell all or any of the Collateral that are Equity Interests pursuant to Section 6.1, each Grantor agrees that, upon request of the Administrative Agent, such Grantor will, at its own expense: 
 (a) execute and deliver, and cause (or, with respect to any issuer which is not a Subsidiary of such Grantor, use its
reasonable efforts to cause) each Pledged Interests Issuer or other issuer of the Collateral contemplated to be sold and the directors and officers thereof to execute and deliver, all such instruments and documents, and do or cause to be done all
such other acts and things, as may be necessary or, in the reasonable opinion of the Administrative Agent, advisable to register such Collateral under the provisions of the Securities Act of 1933, as from time to time amended (the
“Securities Act”), and cause the registration statement relating thereto to become effective and to remain effective for such period as prospectuses are required by law to be furnished, and to make all amendments and supplements
thereto and to the related prospectus which, in the reasonable opinion of the Administrative Agent, are necessary or advisable, all in conformity with the requirements of the Securities Act and the rules and regulations of the SEC applicable
thereto; 
 (b) use its reasonable efforts to exempt the Collateral under the state securities or “Blue
Sky” laws and to obtain all necessary Governmental Approvals for the sale of the Collateral, as requested by the Administrative Agent; 
 (c) cause (or, with respect to any issuer that is not a Subsidiary of such Grantor, use its reasonable efforts to cause) each such Pledged Interests Issuer or other issuer to make available to its
security holders, as soon as practicable, an earnings statement that will satisfy the provisions of Section 11(a) of the Securities Act; and 
 (d) do or cause to be done all such other acts and things as may be reasonably necessary to make such sale of the Collateral or any part thereof valid and binding and in compliance with applicable law.

 Each Grantor acknowledges the impossibility of ascertaining the amount of damages that would be suffered by the Administrative Agent or the
Secured Parties by reason of the failure by such Grantor to perform any of the covenants contained in this Section and consequently agrees that, if such Grantor shall fail to perform any of such covenants, it shall pay, as liquidated damages and not
as a penalty, an amount equal to the value (as reasonably determined by the Administrative Agent in good faith) of such Collateral on the date the Administrative Agent shall demand compliance with this Section 6.2. 
 SECTION 6.3. Compliance with Restrictions. Each Grantor agrees that in any sale of any of the Collateral whenever an Event of Default
shall have occurred and be continuing, the Administrative Agent is hereby authorized to comply with any limitation or restriction in connection with such sale as it may be advised by counsel is necessary in order to avoid any violation of applicable
law (including compliance with such procedures as may restrict the number of prospective bidders and purchasers, require that such prospective bidders and purchasers have certain qualifications, and restrict such prospective bidders and purchasers
to Persons who will represent and agree that they are purchasing for their own account for

  

 Exhibit G – Form of Pledge and Security Agreement 
 Page 28 of 49 

 
investment and not with a view to the distribution or resale of such Collateral), or in order to obtain any required approval of the sale or of the purchaser by any Governmental Authority or
official, and each Grantor further agrees that such compliance shall not result in such sale being considered or deemed not to have been made in a commercially reasonable manner, nor shall the Administrative Agent be liable nor accountable to such
Grantor for any discount allowed by the reason of the fact that such Collateral is sold in compliance with any such limitation or restriction. 
 SECTION 6.4. Indemnity and Expenses. 
 (a)
WITHOUT LIMITING THE GENERALITY OF THE PROVISIONS OF SECTION 9.2 OF
THE CREDIT AGREEMENT, EACH GRANTOR HEREBY INDEMNIFIES AND HOLDS HARMLESS THE
ADMINISTRATIVE AGENT, EACH SECURED PARTY AND EACH OF THEIR RESPECTIVE OFFICERS,
DIRECTORS, EMPLOYEES AND AGENTS (THE “INDEMNIFIED PARTIES”) FROM AND
AGAINST ANY AND ALL CLAIMS, LOSSES AND LIABILITIES ARISING OUT OF OR
RESULTING FROM THIS SECURITY AGREEMENT OR ANY OTHER CREDIT DOCUMENT (INCLUDING,
WITHOUT LIMITATION, ENFORCEMENT OF THIS SECURITY AGREEMENT), EXCEPT CLAIMS, LOSSES
OR LIABILITIES RESULTING FROM ANY INDEMNIFIED PARTY’S GROSS NEGLIGENCE, WILLFUL
MISCONDUCT OR UNLAWFUL ACTS; PROVIDED, HOWEVER, THAT IT IS THE INTENTION OF THE PARTIES HERETO THAT EACH INDEMNIFIED PARTY BE INDEMNIFIED IN THE CASE OF ITS OWN NEGLIGENCE (OTHER
THAN GROSS NEGLIGENCE), REGARDLESS OF WHETHER SUCH NEGLIGENCE IS SOLE OR CONTRIBUTORY, ACTIVE OR PASSIVE, IMPUTED, JOINT OR TECHNICAL. If and to the extent that the foregoing undertaking may be unenforceable for any reason, each Grantor
hereby agrees to make the maximum contribution to the payment and satisfaction of each of the foregoing which is permissible under applicable law. 
 (b) Other than as set forth in clause (c) below, each Grantor will upon demand pay to the Administrative Agent and any local counsel the amount of any and all expenses, including the reasonable fees
and disbursements of its counsel and of any experts and agents, which the Administrative Agent and any local counsel may incur in connection herewith, including without limitation in connection with the administration of this Security Agreement and
the custody, preservation, use or operation of, any of the Collateral. 
 (c) Each Grantor will upon demand pay
to the Administrative Agent and any local counsel the amount of any and all expenses, including the fees and disbursements of its counsel and of any experts and agents, which the Administrative Agent and any local counsel may incur in connection
(i) the sale of, collection from, or other realization upon, any of the Collateral, (ii) the exercise or enforcement of any of the rights of the Administrative Agent and any local counsel or any of the Secured Parties hereunder, or
(iii) the failure by any Grantor to perform or observe any of the provisions hereof. 
 SECTION 6.5. Warranties. The
Administrative Agent may sell the Collateral without giving any warranties or representations as to the Collateral. The Administrative Agent may disclaim any warranties of title or the like. Each Grantor agrees that this procedure will not be
considered to adversely affect the commercial reasonableness of any sale of the Collateral.

“Security Agreement”), among FLOTEK INDUSTRIES, INC., a Delaware corporation and each subsidiary of the Borrower signatory thereto (together with the Borrower, the “Grantors” and individually, a
“Grantor”), in favor of WELLS FARGO BANK, N.A. (“Wells Fargo”), as administrative agent (together with any successor(s) and assign(s) thereto, in such capacity, the “Administrative Agent”) for each
of the Secured Parties (as defined below). 
 A. Reference is made to that certain Credit Agreement, dated as of March 31,
2008 (as amended, supplemented, amended and restated or otherwise modified from time to time, the “Credit Agreement”), among the Borrower, the lenders from time to time parties thereto (the “Lenders”), Wells Fargo

 B. Capitalized terms used herein and not otherwise defined herein shall have the meanings assigned to such terms in the Security Agreement
and the Credit Agreement. 
 C. Section 7.11 of the Security Agreement provides that additional Subsidiaries of the
Borrower may become Grantors under the Security Agreement by execution and delivery of an instrument in the form of this Supplement. The undersigned Subsidiary of the Borrower (the “New Grantor”) is executing this Supplement in
accordance with the requirements of the Credit Agreement to become a Grantor under the Security Agreement. 
 Accordingly, the
Administrative Agent and the New Grantor agree as follows: 
 SECTION 1. In accordance with Section 7.11 of the Security
Agreement, the New Grantor by its signature below becomes a Grantor under the Security Agreement with the same force and effect as if originally named therein as a Grantor and the New Grantor hereby agrees (a) to all the terms and provisions of
the Security Agreement applicable to it as a Grantor thereunder and (b) represents and warrants that the representations and warranties made by it as a Grantor thereunder are true and correct on and as of the date hereof. In furtherance of the
foregoing, the New Grantor, as security for the payment and performance in full of the Secured Obligations (as defined in the Security Agreement), does hereby create and grant to the Administrative Agent, its successors and assigns, for the benefit
of the Secured Parties, their successors and assigns as provided in the Security Agreement, a continuing security interest in and lien on all of the New Grantor’s right, title and interest in and to the Collateral (as defined in the Security
Agreement) of the New Grantor. Each reference to a “Grantor” in the Security Agreement shall be deemed to include the New Grantor. The Security Agreement is hereby incorporated herein by reference.

 SECTION 2. The New Grantor represents and warrants to the Administrative Agent and the other
Secured Parties that this Supplement has been duly authorized, executed and delivered by it and constitutes its legal, valid and binding obligation, enforceable against it in accordance with its terms (subject to applicable bankruptcy,
reorganization, insolvency, moratorium or similar laws affecting creditors’ rights generally and subject, as to enforceability, to equitable principles of general application (regardless of whether enforcement is sought in a proceeding in
equity or at law)). 
 SECTION 3. This Supplement may be executed in counterparts, each of which shall constitute an original,
but all of which when taken together shall constitute a single contract. This Supplement shall become effective when the Administrative Agent shall have received counterparts of this Supplement that, when taken together, bear the signatures of the
New Grantor and the Administrative Agent. Delivery of an executed signature page to this Supplement by facsimile transmission shall be as effective as delivery of a manually signed counterpart of this Supplement. 
 SECTION 4. The New Grantor hereby agrees that the schedules attached to the Security Agreement are hereby supplemented by the corresponding
schedules attached to this Supplement. The New Grantor hereby represents and warrants that the information provided in the schedules attached hereto are true and correct as of the date hereof. 
 SECTION 5. The New Grantor hereby expressly acknowledges and agrees to the terms of Section 6.4. (Indemnity and Expenses) of the
Security Agreement and expressly acknowledges the irrevocable proxy provided in Section 4.1(e) of the Security Agreement. In furtherance thereof, NEW GRANTOR HEREBY GRANTS THE ADMINISTRATIVE AGENT AN IRREVOCABLE PROXY (WHICH IRREVOCABLE
PROXY SHALL CONTINUE IN EFFECT UNTIL THE TERMINATION DATE) EXERCISABLE UNDER THE CIRCUMSTANCES PROVIDED IN SECTION 4.1 OF THE SECURITY AGREEMENT, TO VOTE THE PLEDGED SHARES, PLEDGED INTERESTS, INVESTMENT PROPERTY AND SUCH OTHER COLLATERAL.

 SECTION 6. Except as expressly supplemented hereby, the Security Agreement shall remain in full force and effect.

THE LAWS OF THE STATE OF TEXAS, EXCEPT TO THE EXTENT THAT THE VALIDITY OR PERFECTION OF THE SECURITY INTERESTS HEREUNDER, OR REMEDIES HEREUNDER, IN RESPECT OF ANY PARTICULAR COLLATERAL ARE GOVERNED BY THE LAWS OF A JURISDICTION OTHER THAN THE STATE
OF TEXAS. 
 SECTION 8. In case any one or more of the provisions contained in this Supplement should be held invalid, illegal
or unenforceable in any respect, neither party hereto shall be required to comply with such provision for so long as such provision is held to be invalid, illegal or unenforceable, but the validity, legality and enforceability of the remaining
provisions contained herein and in the Security Agreement shall not in any way be affected or impaired. The parties hereto shall endeavor in good-faith negotiations to replace the invalid, illegal or unenforceable provisions with valid provisions
