A. The Borrower is party to that certain Credit Agreement dated as of January 29, 2010, among the Borrower, the lenders party thereto
from time to time (the “Lenders”), the Administrative Agent, the Swing Line Lender, and the Issuing Lender (as heretofore amended and as may be further amended, restated or otherwise modified from time to time, the “Credit
Agreement”). 
 B. The Borrower failed to comply with the Asset Coverage Ratio covenant under Section 6.18 of the Credit
Agreement (as in effect prior to this Agreement) for the months ended January 31, 2016, February 29, 2016 and March 31, 2016 (collectively, the “Existing Defaults”). 

C. The Borrower has requested that the Lenders waive the Existing Defaults, as provided herein and subject to the terms and conditions set
forth herein. 
 THEREFORE, the Borrower, the Lenders, the Administrative Agent, the Swing Line Lender, and the Issuing Lender hereby agree
as follows: 
 Section 1. Defined Terms. As used in this Agreement, each of the terms defined in the opening paragraph
and the Recitals above shall have the meanings assigned to such terms therein. Each term defined in the Credit Agreement and used herein without definition shall have the meaning assigned to such term in the Credit Agreement, unless expressly
provided to the contrary. 
 Section 2. Other Definitional Provisions. Article, Section, Schedule, and Exhibit references
are to Articles and Sections of and Schedules and Exhibits to this Agreement, unless otherwise specified. All references to instruments, documents, contracts, and agreements are references to such instruments, documents, contracts, and agreements as
the same may be amended, supplemented, and otherwise modified from time to time, unless otherwise specified. The words “hereof,” “herein,” and “hereunder” and words of similar import when used in this Agreement shall
refer to this Agreement as a whole and not to any particular provision of this Agreement. The term “including” means “including, without limitation.” Paragraph headings have been inserted in this Agreement as a matter of
convenience for reference only and it is agreed that such paragraph headings are not a part of this Agreement and shall not be used in the interpretation of any provision of this Agreement. 

Section 3. Waiver. 

(a) The Borrower hereby acknowledges and agrees that each of the Existing Defaults has occurred, is continuing and constitutes an Event of
Default for all purposes under the Credit Documents. 
 (b) Subject to the terms and conditions of this Agreement, the Lenders hereby waive
the Existing Defaults. The waiver by the Lenders is contingent upon the satisfaction of the conditions precedent set forth in Section 5 below and is limited to the Existing Defaults. Such waiver of the Existing Defaults is permanent and is
limited to the extent expressly described herein and shall not be construed to be a consent to or a permanent waiver of noncompliance with Section 6.18 of the Credit Agreement for any periods other than the periods expressly set out herein or
any other terms, provisions, covenants, warranties or agreements contained in the Credit Agreement or in any of the other Credit Documents. 

 (c) The Secured Parties expressly reserve the right to exercise any rights and remedies available
to them in connection with any other present or future defaults with respect to the Credit Agreement (other than the Existing Defaults) or any other provision of any Credit Document. 

(d) The descriptions herein of the Existing Defaults are based upon the information provided to the Lenders on or prior to the date hereof and
shall not be deemed to exclude the existence of any other Defaults or Events of Default. The failure of the Lenders to give notice to any Credit Party of any such other Defaults or Events of Default is not intended to be nor shall be a waiver
thereof. Each Credit Party hereby agrees and acknowledges that the Lenders require and will require strict performance by the Credit Parties of all of their respective obligations, agreements and covenants contained in the Credit Agreement and the
other Credit Documents, and no inaction or action by the Administrative Agent, the Issuing Lender, the Swing Line Lender, or any Lender regarding any Default or Event of Default (including but not limited to the Existing Defaults) under any of the
Credit Documents is intended to be or shall be a waiver thereof other than the permanent waiver of the Existing Defaults expressly provided for in this Section 3. Each Credit Party hereby also agrees and acknowledges that no course of dealing
and no delay in exercising any right, power, or remedy conferred to any Lender in the Credit Agreement or in any other Credit Document or now or hereafter existing at law, in equity, by statute, or otherwise shall operate as a waiver of or otherwise
prejudice any such right, power, or remedy (collectively, the “Lender Rights”). For the avoidance of doubt, each Credit Party also agrees and acknowledges that neither the waiver provided in this Agreement nor any other waiver
provided by the Lenders prior to the date hereof shall operate as a waiver of or otherwise prejudice any of the Lender Rights other than the permanent waiver of the Existing Defaults expressly provided for in this Section 3.

and warranties contained in the Credit Agreement, and the representations and warranties contained in the other Credit Documents, are true and correct in all material respects on and as of the Effective Date as if made on as and as of such date

 Exhibit 10.5 

GUARANTY AGREEMENT 
 This
Guaranty Agreement dated as of April 27, 2016 (as amended, supplemented, amended and restated or otherwise modified from time to time, this “Guaranty”) is executed by each of the undersigned (individually a
“Guarantor” and collectively, the “Guarantors”), in favor of Wells Fargo Bank, National Association, as Administrative Agent (as defined below) for the ratable benefit of the Secured Parties (as defined in the
Credit Agreement). 
 INTRODUCTION 

A. This Guaranty is given in connection with that certain Credit Agreement dated as of January 29, 2010 (as the same may be amended,
restated, supplement or otherwise modified from time to time, the “Credit Agreement”), among the Borrower, the lenders party thereto (the “Lenders”), and Wells Fargo Bank, National Association, as administrative
agent (the “Administrative Agent”), Swing Line Lender and as Issuing Lender for the Lenders. 
 B. Each Guarantor, other
than the Borrower, is a Material Domestic Subsidiary (as defined in the Credit Agreement) of the Borrower and the transactions contemplated by the Credit Agreement and the other Credit Documents (as defined in the Credit Agreement), are (i) in
furtherance of such Guarantor’s corporate purposes, (ii) necessary or convenient to the conduct, promotion or attainment of such Guarantor’s business, and (iii) for such Guarantor’s direct or indirect benefit. 

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, (iii) to induce the Secured Swap providers to enter into Hedging Arrangements with the Credit
Parties, (iv) to induce the Banking Services Providers to provide Banking Services to the Credit Parties and (v) intending it to be a legal, valid, binding, enforceable and continuing obligation of such Guarantor. 

NOW, THEREFORE, in consideration of the premises, each Guarantor hereby agrees 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 Obligations and Secured Swap Obligations (other than Excluded Swap Obligations)), 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”). 

  
 Guaranty Agreement 

Page 1 of 14 

 
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
or any Material Domestic Subsidiary of the Borrower to the Administrative Agent, the Issuing Lender, the Swing Line Lender or any Lender under the Credit Documents and by the Borrower or any Material Domestic Subsidiary of the Borrower to the
Secured Swap Provider or any Banking Services Provider 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 or any Material
Domestic Subsidiary of the Borrower. 
 (b) In order to provide for just and equitable contribution among the Guarantors, the Guarantors
agree that in the event a payment shall be made on any date under this Guaranty by any Guarantor (the “Funding Guarantor”), each other Guarantor (each a “Contributing Guarantor”) shall indemnify the Funding
Guarantor in an amount equal to the amount of such payment, in each case multiplied by a fraction the numerator of which shall be the net worth of the Contributing Guarantor as of such date and the denominator of which shall be the aggregate net
worth of all the Contributing Guarantors together with the net worth of the Funding Guarantor as of such date. Any Contributing Guarantor making any payment to a Funding Guarantor pursuant to this Section 2(b) shall be subrogated to the rights
of such Funding Guarantor to the extent of such payment. 
 (c) Each Qualified ECP Guarantor hereby jointly and severally absolutely,
unconditionally and irrevocably undertakes to provide such funds or other support as may be needed from time to time by each other Credit Party to honor all of its obligations under this Guaranty in respect of Secured Swap Obligations (provided,
however, that each Qualified ECP Guarantor shall only be liable under this Section 2 for the maximum amount of such liability that can be hereby incurred without rendering its obligations under this Section 2, or otherwise under this
Guaranty, voidable under applicable law relating to fraudulent conveyance or fraudulent transfer, and not for any greater amount). The obligations of each Qualified ECP Guarantor under this Section shall remain in full force and effect until the
Termination Date (as defined in the Security Agreement). Each Qualified ECP Guarantor intends that this Section 2 constitute, and this Section 2 shall be deemed to constitute, a “keepwell, support, or other agreement” for the
benefit of each other Credit Party for all purposes of Section 1a(18)(A)(v)(II) of the Commodity Exchange Act. 
 (d) Anything
contained in this Guaranty to the contrary notwithstanding, the obligations of each Guarantor under this Guaranty on any date shall be limited to a maximum aggregate amount equal to the largest amount that would not, on such date, render its
obligations hereunder subject to avoidance as a fraudulent transfer or conveyance under Section 548 of the United States Bankruptcy Code (11 U.S.C. §§ 101 et seq) or any applicable provisions of comparable laws relating to bankruptcy,
insolvency, or reorganization, or relief of debtors (collectively, the “Fraudulent Transfer Laws”), but only to the extent that any Fraudulent Transfer Law has been found in a final non-appealable judgment of a court of competent
jurisdiction to be applicable to such obligations as of such date, in each case: 
 (i) after giving effect to all liabilities of such
Guarantor, contingent or otherwise, that are relevant under the Fraudulent Transfer Laws, but specifically excluding: 
 (A) any liabilities
of such Guarantor in respect of intercompany indebtedness to the Borrower or other affiliates of the Borrower to the extent that such indebtedness would be discharged in an amount equal to the amount paid by such Guarantor hereunder; 

  
 Guaranty Agreement 

Page 2 of 14 

 (B) any liabilities of such Guarantor under this Guaranty; and 

(C) any liabilities of such Guarantor under each of its other guarantees of and joint and several co-borrowings of Debt, in each case entered
into on the date this Guaranty becomes effective, which contain a limitation as to maximum amount substantially similar to that set forth in this Section 2(d) (each such other guarantee and joint and several co-borrowing entered into on the
date this Guaranty becomes effective, a “Competing Guaranty”) to the extent such Guarantor’s liabilities under such Competing Guaranty exceed an amount equal to (1) the aggregate principal amount of such Guarantor’s
obligations under such Competing Guaranty (notwithstanding the operation of that limitation contained in such Competing Guaranty that is substantially similar to this Section 2(d)), multiplied by (2) a fraction (i) the numerator of
which is the aggregate principal amount of such Guarantor’s obligations under such Competing Guaranty (notwithstanding the operation of that limitation contained in such Competing Guaranty that is substantially similar to this
Section 2(d)), and (ii) the denominator of which is the sum of (x) the aggregate principal amount of the obligations of such Guarantor under all other Competing Guaranties (notwithstanding the operation of those limitations contained
in such other Competing Guaranties that are substantially similar to this Section 2(d)), (y) the aggregate principal amount of the obligations of such Guarantor under this Guaranty (notwithstanding the operation of this Section 2(d)),
and (z) the aggregate principal amount of the obligations of such Guarantor under such Competing Guaranty (notwithstanding the operation of that limitation contained in such Competing Guaranty that is substantially similar to this
Section 2(d)); and 
 (ii) after giving effect as assets to the value (as determined under the applicable provisions of
the Fraudulent Transfer Laws) of any rights to subrogation, reimbursement, indemnification or contribution of such Guarantor pursuant to applicable law or pursuant to the terms of any agreement (including any such right of contribution under
Section 2(b)). 
 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, any Secured Swap Provider or any Banking Services Provider with respect thereto but subject to Section 2(d) 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 or any Banking Services, 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 

  
 Guaranty Agreement 

Page 3 of 14 

 
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 Secured Swap Provider or Banking Services with a Banking Services Provider, 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 Secured Swap Provider or Banking Services with a Banking Services Provider, including,
without limitation, any increase in the Guaranteed Obligations resulting from the extension of additional credit to the Borrower or otherwise; 

(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 Guarantor; 
 (e) any change, restructuring or termination of the corporate structure or existence of the
Borrower or any Guarantor; 
 (f) any failure of any Lender, the Administrative Agent, the Issuing Lender, the Swing Line Lender or any
other Secured Party 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 Secured Party (and each Guarantor hereby irrevocably waives any duty on the part of any Secured Party to disclose such information); 

(g) any signature of any officer of the Borrower or any Guarantor being mechanically reproduced in facsimile or otherwise; or 

(h) any other circumstance or any existence of or reliance on any representation by any Secured Party that might otherwise constitute a
defense available to, or a discharge of, the Borrower, any Guarantor or any other guarantor, surety or other Person. 

  
 Guaranty Agreement 

Page 4 of 14 

 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 Secured Party 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 SECURED PARTY 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 SECURED PARTY’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 SECURED PARTY’S GROSS NEGLIGENCE OR WILLFUL MISCONDUCT; PROVIDED, HOWEVER, THAT IT IS THE INTENTION OF THE PARTIES HERETO THAT EACH INDEMNIFIED SECURED 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. 

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 Secured Party 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 (i) the financing arrangements involving the Borrower or any Guarantor contemplated by the Credit Documents, (ii) the Hedging Arrangements with a Secured Swap Provider and (iii) the
Banking Services provided to any Guarantor by a Banking Services Provider, 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,

  
 Guaranty Agreement 

Page 5 of 14 

 
reimbursement, exoneration, contribution or indemnification and any right to participate in any claim or remedy of any Secured Party 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 the Termination Date (as defined in the Security Agreement). If any amount shall be paid to a Guarantor in violation of the preceding sentence at
any time prior to or on the Termination Date (as defined in the Security Agreement), such amount shall be held in trust for the benefit of the Secured Parties 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 agrees that, until after the Termination Date (as defined in the Security Agreement), 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 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 agrees that none 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. “Subordinated Guarantor Obligations” means any and all obligations and liabilities of a Guarantor
owing to the Borrower or any other Guarantor, direct or contingent, due or to become due, now existing or hereafter arising, including, without limitation, all future advances, with interest, attorneys’ fees, expenses of collection and costs.

(b) Such Guarantor has, independently and without reliance upon the Administrative Agent or any Lender and based on such documents and
information as it has deemed appropriate, made its own credit analysis and decision to enter into this 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, financial condition, operations and properties of the Borrower and each other relevant Person.

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

Guaranty, irrespective of whether or not such Secured Party shall have made any demand under this Guaranty and although such obligations may be contingent and unmatured.

SUPPLEMENT NO.          dated as of
                     (the “Supplement”), to the Guaranty Agreement dated as of April 27, 2016 (as amended, supplemented
or otherwise modified from time to time, the “Guaranty Agreement”), among CARBO Ceramics Inc. (the “Borrower”), each Material Domestic Subsidiary of Borrower party thereto (individually, a
“Guarantor” and collectively, the “Guarantors”) and WELLS FARGO BANK, NATIONAL ASSOCIATION, as Administrative Agent (the “Administrative Agent”) for the benefit of the Administrative Agent and the
Lenders (as defined below, together with the Administrative Agent, each a “Secured Party”)). 
 A. Reference is made to the
Credit Agreement dated as of January 29, 2010 (as amended, restated, supplemented or otherwise modified from time to time, the “Credit Agreement”), among the Borrower, the lenders from time to time party thereto (the
“Lenders”), Wells Fargo Bank, National Association, as 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 Material Domestic 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 Secured Parties 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)).

 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 Secured Party to serve legal process in any other manner permitted by the law or affect the
right of any Secured Party to bring any action or proceeding against the New Guarantor or its Property in the courts of any other jurisdiction. 

SECTION 6. THE NEW GUARANTOR HEREBY KNOWINGLY, VOLUNTARILY AND INTENTIONALLY WAIVES TO THE FULLEST EXTENT PERMITTED BY LAW ANY
RIGHTS IT MAY HAVE TO A TRIAL BY JURY IN RESPECT OF ANY LITIGATION BASED HEREON, OR ARISING OUT OF, UNDER, OR IN CONNECTION WITH, EACH CREDIT DOCUMENT, OR ANY COURSE OF CONDUCT, COURSE OF DEALING, STATEMENTS (WHETHER ORAL OR WRITTEN) OR ACTIONS OF
THE ADMINISTRATIVE AGENT, ANY OTHER SECURED PARTY OR ANY OBLIGOR IN CONNECTION THEREWITH. THE NEW GUARANTOR ACKNOWLEDGES AND AGREES THAT IT HAS RECEIVED FULL AND SUFFICIENT CONSIDERATION FOR THIS PROVISION (AND EACH OTHER PROVISION OF EACH OTHER
CREDIT DOCUMENT TO WHICH IT IS A PARTY) AND THAT THIS PROVISION IS A MATERIAL INDUCEMENT FOR THE ADMINISTRATIVE AGENT, EACH LENDER AND ISSUING LENDER ENTERING INTO THE CREDIT DOCUMENTS.

 SECTION 7. 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.
