(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 herein (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 2.11, 2.13, 2.14, and 9.2 but after taking into account payments effected pursuant to Section 9.1) in accordance with each Lender’s applicable Pro Rata Share to the Lenders for the account of their respective applicable Lending Offices, and like funds relating to the payment of any other amount payable to any Lender to such Lender for the account of its applicable Lending Office, in each case to be applied in accordance with the terms of this Agreement. Upon receipt of other amounts due solely to the Administrative Agent 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.

(d) Computations . All computations of interest shall be made by the Administrative Agent on the basis of a year of 365/366 days, in each case for the actual number of days (including the first day, but excluding the last day) occurring in the period for which such interest or fees are payable. Each determination by the Administrative Agent of an amount of interest or fees shall be conclusive and binding for all purposes, absent manifest error.

(e) Sharing of Payments, Etc . If any Lender shall obtain any payment (whether voluntary, involuntary, through the exercise of any right of set-off, or otherwise) on account of the Term Loans made by it in excess of its Pro Rata Share of payments on account of the Term Loans obtained by the Lenders, such Lender shall notify the other Lenders and forthwith purchase from the other Lenders such participations in the Term Loans made 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 Pro Rata 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 any Credit Party under any of the Credit Documents to the Administrative Agent or a Lender shall be made, in accordance with Section 2.12, free and clear of and without deduction for any Taxes, excluding, in the case of the Administrative Agent or a Lender, (i) Taxes imposed on or measured by its net income or franchise Taxes imposed as a result of such Administrative Agent or such Lender being organized under the laws of, or having its principal executive office or, in the case of any Lender, having its applicable Lending Office located in the jurisdiction (or any political subdivision thereof) imposing such Tax, and (ii) in the case of a Lender, any United States federal withholding Taxes imposed on amounts payable to or for the account of such Lender with respect to an applicable interest in an Obligation, if and to the extent such United States federal withholding Taxes are in effect on the date a Lender becomes a Lender hereunder (other than pursuant to an assignment request by the Borrower under Section 2.14) (all such nonexcluded Taxes being hereinafter referred to as “ Indemnified Taxes ”). Except as provided in Section 2.13(f), if the Borrower shall be required by law to deduct any Indemnified Taxes from or in respect of any sum payable to the

-19-

Administrative Agent 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, or at the option of the Administrative Agent timely reimburse it for the payment of, any present or future stamp, court or documentary, intangible, recording, filing or similar 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, performance, enforcement or registration of, from the receipt or perfection of a security interest under, 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 SHALL INDEMNIFY EACH LENDER AND THE ADMINISTRATIVE AGENT FOR THE FULL AMOUNT OF INDEMNIFIED TAXES OR OTHER TAXES (INCLUDING, WITHOUT LIMITATION, ANY INDEMNIFIED TAXES OR OTHER TAXES IMPOSED ON AMOUNTS PAYABLE UNDER THIS SECTION 2.13) PAID BY SUCH 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. A CERTIFICATE AS TO THE AMOUNT OF SUCH PAYMENT OR LIABILITY DELIVERED TO THE BORROWER BY A LENDER (WITH A COPY TO THE ADMINISTRATIVE AGENT), OR BY THE ADMINISTRATIVE AGENT ON ITS OWN BEHALF OR ON BEHALF OF A LENDER, SHALL BE CONCLUSIVE ABSENT MANIFEST ERROR.

(d) Evidence of Tax Payments . As soon as practicable after any payment of Indemnified Taxes or Other Taxes by any Credit Party to a Governmental Authority, the Borrower shall deliver to the Administrative Agent the original or a certified copy of any receipt issued by such Governmental Authority evidencing such payment, a copy of the return reporting such payment or other evidence of such payment reasonably satisfactory to the Administrative Agent.

(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 or reduction of 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 an applicable Internal Revenue Service Form 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 or at a reduced rate of 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 Section 2.13(e) (unless such failure is due to a change in treaty, law or regulation occurring after the date on which such Lender becomes a Lender hereunder), such Lender shall not be entitled to indemnification or payment under Section 2.13(a), (b), or (c) with respect to Indemnified 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 Indemnified 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 Indemnified 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 Indemnified 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. Borrower hereby agrees to pay all reasonable costs and expenses incurred by any Lender in connection with any such designation or assignment.

-20-

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

(i) Payment . If the Administrative Agent or any Lender becomes entitled to receive payment of Indemnified 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 Indemnified Taxes, Other Taxes or additional sums within 10 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 2.11 or 2.13 to make any additional payment to any Lender or to any Governmental Authority for the account of any Lender pursuant to Section 2.13, and, with respect to a payment pursuant to Section 2.13, such Lender has declined or is unable to designate a different lending office in accordance with Section 2.13(g) (any such Lender being a “ Subject Lender ”), the Borrower may, upon notice to the Subject Lender and the Administrative Agent and at the Borrower’s sole cost and expense, require such Subject Lender to assign and delegate, without recourse (in accordance with and subject to the restrictions contained in, and consents required by, Section 9.7), all of its interests, rights and obligations under this Agreement and the related Credit Documents to an Eligible Assignee that shall assume such obligations (which assignee may be another Lender, if a Lender accepts such assignment), provided that, in any event

(A) as to assignments requested by the Borrower, the Borrower shall have paid to the Administrative Agent the assignment fee specified in Section 9.7;

(B) such Subject Lender shall have received payment of an amount equal to the outstanding principal of its Term Loans, accrued interest thereon, accrued fees and all other amounts payable to it hereunder and under the other Credit Documents from the assignee (to the extent of such outstanding principal and accrued interest and fees) or the Borrower (in the case of all other amounts, if applicable);

(C) in the case of any such assignment resulting from a claim for compensation under Section 2.13, such assignment will result in a reduction in such compensation or payments thereafter; and

(D) such assignment does not conflict with applicable Legal Requirements.

A Lender shall not be required to make any such assignment or delegation if, prior thereto, as a result of a waiver by such Lender or otherwise, the circumstances entitling the Borrower to require such assignment and delegation cease to apply.

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

(b) No Default has occurred and is continuing.

Section 4.9 Pension Plans .

Based upon GAAP existing as of the date of this Agreement and current factual circumstances, no Credit Party has any reason to believe that the annual cost during the term of this Agreement to the Borrower or any Subsidiary for post-retirement benefits to be provided to the current and former employees of the Borrower or any Subsidiary under Plans that are welfare benefit plans (as defined in Section 3(1) of ERISA) could, in the aggregate, reasonably be expected to cause a Material Adverse Change.

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

Section 8.2 Reliance by Administrative Agent . The Administrative Agent shall be entitled to rely upon any certification, notice, instrument, writing, or other communication (including, without limitation, any thereof by telephone or telecopy) believed by it to be genuine and correct and to have been signed, sent or made by or on behalf of the proper Person or Persons, and upon advice and statements of legal counsel (including counsel for any Credit Party), independent accountants, and other experts selected by the Administrative Agent.

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

Section 8.4 Rights as Lender .

-44-

Affiliates may (without having to account therefor to any Lender) accept deposits from, lend money to, make investments in, provide services to, and generally engage in any kind of lending, trust, or other business with any Credit Party or any of its Subsidiaries or Affiliates as if it were not acting as Administrative Agent, and Wilks Brothers, LLC (and any successor acting as Administrative Agent) and its Affiliates may accept fees and other consideration from any Credit Party or any of its Subsidiaries or Affiliates for services in connection with this Agreement or otherwise without having to account for the same to the Lenders.

WITHOUT LIMITATION OF THE FOREGOING, EACH LENDER AGREES TO REIMBURSE THE ADMINISTRATIVE AGENT PROMPTLY UPON DEMAND FOR ITS PRO RATA SHARE (AS DEFINED HEREIN) OF ANY OUT-OF-POCKET EXPENSES (INCLUDING COUNSEL FEES) INCURRED BY THE ADMINISTRATIVE AGENT IN CONNECTION WITH THE PREPARATION, EXECUTION, DELIVERY, ADMINISTRATION, MODIFICATION, AMENDMENT, OR ENFORCEMENT (WHETHER THROUGH NEGOTIATIONS, WORKOUT, LEGAL PROCEEDINGS, OR OTHERWISE) OF, OR LEGAL ADVICE IN RESPECT OF RIGHTS OR RESPONSIBILITIES UNDER, THIS AGREEMENT OR ANY OTHER CREDIT DOCUMENT, TO THE EXTENT THAT THE ADMINISTRATIVE AGENT IS NOT REIMBURSED FOR SUCH BY THE BORROWER.

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

Section 8.7 Resignation of Administrative Agent . The Administrative Agent may resign at any time by giving written notice thereof to the Lenders and the Borrower. Upon receipt of notice of any such resignation, the Majority Lenders shall have the right to appoint a successor Administrative Agent with, so long as no Event of Default has occurred and is continuing, the consent of the Borrower, which consent shall not be unreasonably withheld or delayed. If no successor Administrative Agent shall have been so appointed by the Majority Lenders with the consent of the Borrower, and shall have accepted such appointment, within 30 days after the retiring Administrative Agent’s giving of notice of resignation, then the retiring Administrative Agent may, on behalf of the Lenders and the Borrower, appoint a successor Administrative Agent, which shall be, in the case of a successor agent, a commercial bank organized under the laws of the United States of America or of any State thereof and having a combined capital and surplus of at least $250,000,000; provided that , if the Administrative Agent shall notify the Borrower and the Lenders that no qualifying Person has accepted such appointment, then such resignation shall nonetheless become effective in accordance with such notice and (1) the retiring Administrative Agent shall be discharged from its duties and obligations hereunder and under the other Credit Documents (except that in the case

After any retiring Administrative Agent ’ s resignation as Administrative Agent, the provisions of this Article 8 shall inure to its benefit as to any actions taken or omitted to be taken by it while it was Administrative Agent under this Agreement and the other Credit 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 (but Administrative Agent shall not be obligated to take any of such actions without being so directed by the Majority Lenders).

The Lenders acknowledge and agree that the Administrative Agent shall be permitted to rely on, and shall not be liable in any respect for relying upon any certificate delivered in accordance with the immediately preceding sentence (and releasing the Liens from the Collateral sold in the Disposition in question).

(c) Notwithstanding anything contained in any of the Credit Documents to the contrary but subject to Section 7.8(b) hereof, the Credit Parties, the Administrative Agent, and each Secured Party hereby agree that no Secured Party shall have any right individually to realize upon any of the Collateral or to enforce the Guaranties, it being understood and agreed that all powers, rights and remedies hereunder, under the Guaranties and under the Security Documents may be exercised solely by Administrative Agent on behalf of the Secured Parties in accordance

-46-

with the terms hereof and the other Credit Documents. By accepting the benefit of the Liens granted pursuant to the Security Documents, each Secured Party not party hereto hereby agrees to the terms of this paragraph (c).

Section 9.10 Business Loans . Each Credit Party warrants and represents that the Obligations 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.

-50-

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

Section 2.01.  Exercise .

(a) From and after the Original Issue Date, this Warrant shall entitle the Holder to purchase (subject to the terms and conditions contained herein, including Section 2.01(b) ) [•] shares of Common Stock at a price of $[•] per share of Common Stock (the “ Exercise Price ”), in each case subject to adjustment pursuant to Article III .

(b) Notwithstanding anything to the contrary contained herein, until receipt of the Stockholder Approval the Holder shall not be entitled to exercise this Warrant to the extent that the number of shares of Common Stock to be purchased upon such exercise, plus the number of shares of Common Stock purchased on any prior exercise of this Warrant, exceeds [•] shares of Common Stock.

(c) The Warrant shall be exercisable at the option of the Holder at any time from and after the Original Issue Date and on or prior to the Expiration Date.

Section 2.02.  Expiration of the Warrant . The Warrant shall expire at 11:59 p.m., New York City time, on December 31, 2022 (the “ Expiration Date ”), and the Warrant may not be exercised thereafter.

Section 2.03.  Manner of Exercise .

(a) The Warrant may be exercised by the surrender to the Company at the office of the Company of this Warrant together with the form of election attached hereto as Exhibit A (the “ Warrant Exercise Notice ”) duly filled in and signed by the Holder, stipulating the applicable number of Warrant Shares to be exercised, the manner of payment of the Warrant together with payment to the Company of the aggregate Exercise Price due in respect of such exercise as provided in the immediately following sentence. Such payment shall be made, at the option of the Holder, in cash or by certified or official bank check payable to the order of the Company, or by wire transfer of funds to an account designated by the Company for such purpose, in an amount equal to the product of (A) the Exercise Price as of the Exercise Date and (B) the number of Warrant Shares to be exercised as set forth in such Warrant Exercise Notice. The rights represented by the Warrant shall be exercisable at the election of the Holder either in full at any time or from time to time in part. Notwithstanding anything to the contrary in this Warrant, a Warrant Exercise Notice will become irrevocable when executed and delivered to the Company.

(b) Unless the purchase rights represented by this Warrant shall have expired or shall have been fully exercised, the Company shall, at the time of delivery of the Warrant Shares being issued in accordance with Section 2.04 hereof, deliver to the Holder a new Warrant evidencing the rights of the Holder to purchase the unexpired and unexercised Warrant Shares called for by this Warrant. Such new Warrant shall in all other respects be identical to this Warrant.

Section 2.04.  Issuance of Warrant Shares .

(a) Subject to the other provisions of this Warrant, no later than the third Business Day following the Exercise Date of the Warrant, the Company shall issue and cause the Company’s stock transfer agent to countersign and deliver to or upon the written order of the Holder and in such name or names as the Holder may designate, a certificate for the number of Warrant Shares so purchased upon the exercise of such Warrant, together with any cash to be paid in respect of any fractional Warrant Shares pursuant to Section 2.05 ; provided, however, that, at the Company’s election, the Company may deliver such Warrant Shares in uncertificated form. The Person in whose name any Warrant Share is to be issued upon exercise of the Warrant in accordance with its terms will be deemed to become the holder of record of such Warrant Share as of the related Exercise Date.

(b) The Company shall pay any and all documentary, stamp and similar issue or transfer tax due on the issuance of shares of Common Stock upon the exercise of the Warrant, provided , that the Holder of the Warrant shall pay any tax or governmental charge that may be imposed with respect to any applicable withholding or any tax

5

Ex h ibit E – Fo r m of W a r r a n t

which is due because the Holder requests any such shares of Common Stock to be issued in a name other than the Holder ’ s name if such taxes would not have been due had such shares of Common Stock been issued in the Holder ’ s name. Notwithstanding anything to the contrary, if the Company is required to pay withholding taxes or backup withholding on or with respect to any deemed (or constructive) distribution on behalf of the Holder of the Warrant under Section 305(c) of the U.S. Internal Revenue Code of 1986, as amended (the “ Code ” ) (including as a result of an adjustment pursuant to Article III or the lack thereof), the Company may, at its option, set off such payments against subsequent deliveries of, or with respect to, the Warrant.

Section 2.05.  Fractional Warrant Shares . Notwithstanding anything to the contrary in this Warrant, the Company shall not be required to issue fractional Warrant Shares on the exercise of the Warrant. If any fraction of a Warrant Share would, except for the provisions of this Section 2.05 , be issuable upon the exercise of the Warrant, the Company shall, in lieu of issuing fractional shares, either (i) pay an amount in cash equal to the Market Price per Warrant Share on the Exercise Date, multiplied by such fraction, computed to the nearest whole cent or (ii) deliver an additional whole share of Common Stock.

Section 2.06.  Reservation and Authorization of Warrant Shares .

(a) At any time that the Warrant is outstanding, the Company shall take all lawful action within its control to reserve a sufficient number of authorized but unissued shares of Common Stock to satisfy the exercise requirements of the Warrant (giving effect to any adjustments to the number of shares of Common Stock to be issued upon exercise of the Warrants pursuant to Article III ).

(b) Before taking any action which would cause an adjustment pursuant to Article III to reduce the Exercise Price below the then-par value of the Common Stock, the Company shall use its commercially reasonable efforts to take any and all corporate action which may, in the opinion of its counsel (which may be counsel employed by the Company), be necessary in order that the Company may validly and legally issue fully paid and nonassessable shares of Common Stock at the Exercise Price as so adjusted.

(c) The Company covenants that all Warrant Shares which may be issued upon exercise of the Warrant shall, upon issue, be fully paid, nonassessable, free of preemptive rights, free from all taxes and free from all liens, charges and security interests created by the Company with respect to the issue thereof (other than restrictions arising under applicable securities laws or liens created by the Holder).

Section 2.07.  Stock Exchange Listing .The Company shall from time to time use its commercially reasonable efforts to take all actions that may be necessary so that the Warrant Shares, after their issuance upon the exercise of the Warrant, will be listed on the principal securities exchange or other market within the United States of America, if any, on which other shares of Common Stock are then listed (including all actions that may be required under any federal or state law now or in the future applicable to any such listing or any applicable governing rule or regulation of such securities exchange or other market).

Section 2.08.  Replacement of Warrant on Loss . Upon receipt of evidence of the loss, theft, destruction or mutilation of this Warrant and upon delivery of an indemnity, in each case reasonably satisfactory to the Company and, in case of mutilation, upon surrender of such Warrant for cancellation to the Company, the Company shall execute and deliver to the Holder, in lieu hereof, a new Warrant of like tenor and exercisable for an equivalent number of Warrant Shares as the Warrant so lost, stolen, mutilated or destroyed; provided , that, in the case of mutilation, no indemnity shall be required if this Warrant in identifiable form is surrendered to the Company for cancellation.

ARTICLE III

ANTIDILUTION AND RELATED PROVISIONS

Section 3.01.  Adjustment for Change In Capital Stock .

(a) Excluding distributions covered by Section 3.01(b) , if the Company (i) pays a dividend or makes a distribution on any class of its Common Stock in shares of any class of its Common Stock; (ii) subdivides its outstanding shares of any class of Common Stock into a greater number of shares; (iii) combines its outstanding shares of any class of Common Stock into a smaller number of shares; or (iv) makes a distribution on any class of its Common Stock in shares of its Capital Stock (other than such class of Common Stock) or in the form of any other security (including, without limitation, any rights, options or warrants to acquire any security); then, the Exercise Price and number and class of Warrant Shares to be issued for the Warrant shall be proportionately adjusted and/or changed such that the Holder of the Warrant shall be entitled to receive the aggregate number and kind of shares of Common Stock, Capital Stock or other securities which the Holder would have owned or would have been entitled to receive if the Warrant had been exercised immediately prior to such action. Distributions or adjustments pursuant to this Section 3.01(a) shall be made successively whenever any event listed in (i) – (iv) above shall occur. Distributions and adjustments to the Warrant shall become effective immediately after the effective date of the related action or event.

(b) If the Company at any time or from time to time after the date hereof shall distribute to all holders of its Common Stock rights, options, warrants or other securities exercisable for or convertible into Common Stock at a price per share of Common Stock less than the Market Price of the Common Stock on the record date for such distribution, then, in each case, the relevant Exercise Price shall be adjusted in accordance with the following formula:

where:

E2 = the adjusted Exercise Price. E1 = the current Exercise Price.

O = the number of shares of Common Stock outstanding on the record date for such distribution.

N = the number of additional shares of Common Stock issuable pursuant to such rights, options, warrants or other securities.

P = the exercise price per share of the additional shares of Common Stock issuable pursuant to such rights, options, warrants or other securities.

M = the Market Price of the Common Stock on the record date for such distribution.

The adjustment shall be made successively whenever any such options, warrants or other rights (however classified) are issued and shall become effective immediately after the record date for the determination of stockholders entitled to receive the options, warrants or other rights (however classified). If at the end of the period during which such rights, options or warrants are exercisable, not all options, warrants or other rights (however classified) shall have been exercised, the Exercise Price shall be immediately readjusted to what it would have been if “N” in the above formula had been the number of shares actually issued.

Section 3.02.  When No Adjustment Required .

(a) No other adjustments are required to be made under this Article III other than as expressly specified herein, including the amount of any dividend or distribution in cash or other assets (other than Common Stock or

7

Ex h ibit E – Fo r m of W a r r a n t

Capital Stock pursuant to Section 3.01 ) or any issuance of Common Stock or other interests exchangeable for or convertible into Common Stock.

(b) No adjustment shall be made to the Exercise Price or the number and class of Warrant Shares to be issued for the Warrant for any event listed in (i) – (iv) of Section 3.01(a) if the Company makes provisions for the Holder to participate in such transaction without exercising the Warrant on a basis and with notice that the Board determines in good faith to be fair and appropriate.

(c) If the Company takes a record of the holders of Common Stock for the purpose of entitling them to receive a dividend or other distribution, and thereafter (and before the dividend or distribution has been paid or delivered to stockholders) legally abandons its plan to pay or deliver such dividend or distribution, then no adjustment to the Exercise Price or the number and class of Warrant Shares to be issued for the Warrant then in effect shall be required by reason of the taking of such record.

Section 3.03.  Reorganization Events .

(a) In the event of any reclassification, recapitalization or reorganization of the Common Stock (other than in connection with an event to which Section 3.01 applies) or any statutory exchange, merger, consolidation or other similar business combination of the Company with or into another Person, or the sale of all or substantially all of the Company’s assets, pursuant to which, in any such case, the Common Stock is changed or converted into, or exchanged for, or entitled to receive, cash, securities or other property of the Company or another Person (each of which is referred to as a “ Reorganization Event ”), the Warrant will, without the consent of the Holder and subject to Section 3.03(b) , remain outstanding, but shall become exercisable for the number, kind and amount of securities, cash and other property (the “ Exchange Property ”) that the Holder of the Warrant would have received in such Reorganization Event had the Holder exercised the Warrant into the applicable number of shares of Common Stock immediately prior to the effective date of the Reorganization Event. The Company shall not affect any such Reorganization Event unless prior to the consummation thereof, the successor entity (if other than the Company) resulting from such transaction or the entity purchasing such assets assumes by written instrument the obligation to deliver to the Holder such Exchange Property as, in accordance with the foregoing provisions, such Holder may be entitled to acquire. For this purpose,

(i) if the Reorganization Event provides for different treatment of Common Stock held by the Person (other than the Company) that is a party to such Reorganization Event (any such Person, a “ Constituent Person ”), or an Affiliate of a Constituent Person, the Holder shall be deemed to not be a Constituent Person or an Affiliate of a Constituent Person; and

(ii) if the kind or amount of securities, cash and other property receivable upon such Reorganization Event is not the same for each share of Common Stock held immediately prior to such Reorganization Event (other than shares held by a Constituent Person or an Affiliate thereof), the kind and amount of securities, cash and other property receivable upon such Reorganization Event will be deemed to be the weighted average of the types and amounts of consideration received by the holders of Common Stock (other than the Constituent Person and its Affiliates).

(b)  Successive Reorganization Events . The provisions of Section 3.03(a) shall similarly apply to successive Reorganization Events and the provisions of Article III shall apply to any securities received by the holders of the Common Stock in any such Reorganization Event.

Section 3.04.  Notice of Certain Transactions . In the event that (a) the Board authorizes any of the actions listed in Section 3.01(b) or in clauses (i) – (iv) of Section 3.01(a) or (b) the Company enters into a binding agreement for a Reorganization Event, the Company shall send to the Holder a notice of such action or agreement. Such notice shall specify the record date (if applicable) for such action, or the date such action is to take place and the date of participation therein by the holders of Common Stock, if any such date is to be fixed, and shall briefly indicate the effect, if any, of such action on the Common Stock and the Warrant and the manner in which any election to be made by the Holder shall be notified to the Company. Such notice shall be given at least ten (10) Business Days prior to any applicable record date or the date of the taking of such proposed action or the date of participation therein by the holders of Common Stock, whichever shall be the earlier.

Ex h ibit E – Fo r m of W a r r a n t

Section 3.05.  Stockholder Rights Plans . To the extent the Company has a rights plan in effect upon exercise of the Warrant, the Holder shall receive, in addition to any shares of Common Stock issuable upon such exercise, the associated rights issued under such rights plan unless, prior to exercise, the rights have separated from the Common Stock, in which case, the Company shall distribute to the Holder the number of such rights as the Holder would have been entitled to receive if the Warrant had been exercised immediately prior to such separation, subject to readjustment in the event of the expiration, termination or redemption of such rights.

In lieu of any such adjustment, the Company may amend such applicable rights plan to provide that upon exercise of Warrant the Holder will receive, in addition to the Common Stock issuable upon such conversion, the rights which would have attached to such Common Stock if the rights had not become separated from the Common Stock under such applicable rights plan.

ARTICLE IV

Section 4.01.  Transfer Restrictions Generally .

Such financial institution shall be subject to all terms and conditions of this Warrant (including the transfer restrictions set forth in this Article IV ).

(b) In connection with a Transfer of Warrant Shares pursuant to clause (II) in the legend set forth in Section 4.02(a) , the Company shall promptly cause the legend to be removed from any such Warrant Shares upon delivery by the holder of such Warrant Share(s) to the Company and/or and the transfer agent for such shares of Common Stock such legal opinions, certificates or other documentation or evidence as may reasonably be required by either of them to determine that such transfer complies with the Securities Act and other applicable U.S. securities laws.

(c)  Representations of the Holder . In connection with the issuance of the Warrant, the Holder specifically represents, as of the date hereof, to the Company by acceptance of the Warrant as follows:

It is agreed that no delay or omission to exercise any right, power or remedy accruing to any party, upon any breach, default or noncompliance by another party under this Warrant, shall impair any such right, power or remedy, nor shall it be construed to be a waiver of any such breach, default or noncompliance, or any acquiescence therein, or of or in any similar breach, default or noncompliance thereafter occurring.

Ladies and Gentlemen:

Reference is made to (i) that certain Amended and Restated Credit Agreement (the “ Credit Agreement ”), dated as of March 2, 2017, pursuant to which Wilks Brothers, LLC, a Texas limited liability company (the “ Stockholder ”), has agreed to provide certain financing to the CARBO Ceramics Inc., a Delaware corporation (the “ Company ”), and (ii) that certain Warrant (the “ Warrant ”), dated as of the date hereof, between the Company and the Stockholder.  Certain capitalized terms used in this letter agreement shall have the meanings ascribed to such terms in Section 6 .

In order to induce the parties to enter into the Credit Agreement and the Warrant and for other good and valuable consideration, the Company, each Supporting Stockholder (solely with respect to his obligations under Section 3(b) and Article 7 ), and the Stockholder have agreed to enter into this letter agreement (this “ Stockholder Agreement ”).

1. Standstill Restrictions.  

(a) The Stockholder shall not, and shall cause its Affiliates not to, Transfer any Voting Securities to any Person or Group who, to the Stockholder’s actual knowledge, after giving effect to such Transfer, would Beneficially Own ten percent (10%) or more of the outstanding Voting Securities; provided that the foregoing restriction shall not apply to a Transfer to any Person or Persons who are acquiring majority control of the Company pursuant to a merger, tender offer or similar business combination transaction approved or recommended by the Board.  This

1

provision shall terminate and be of no further force and effect with respect to the Stockholder on the first date when the Stockholder and its Affiliates Beneficially Own less than five percent of the outstanding Voting Securities.  Any Transfer or attempted Transfer of Voting Securities in violation of this Section 1(a) shall, to the fullest extent permitted by applicable Law, be null and void ab initio , and the Company shall not, and shall instruct its transfer agent and other third parties not to, record or recognize any such purported transaction on the share register of the Company.

(b) From and after the date hereof until the six-month anniversary of the date on which the Stockholder and its Affiliates cease to Beneficially Own Voting Securities representing at least five percent (5%) (the “ Ownership Threshold ”) of the Voting Securities outstanding at such time, the Stockholder agrees that, without the prior written consent of the Board, the Stockholder shall not, and shall cause each of its Affiliates and its and their representatives acting on their behalf not to, directly or indirectly, alone or acting together with any other Person, except as otherwise expressly set forth in this Section 1(b) :

2

2. Registration Rights.   On the date hereof, the Company and the Stockholder shall enter a registration rights agreement in substantially the form attached hereto as Exhibit A (the “ Registration Rights Agreement ”).

3. Stockholder Approval.  

(a) The Company shall, at the Company’s 2017 annual meeting and in accordance with Section 312.03(b) of the New York Stock Exchange Listed Company Manual, submit a proposal seeking the approval, by an affirmative vote of the holders of a majority of the votes cast of the Voting Securities, of the issuance of 523,022 shares of Common Stock to the Stockholder pursuant to and in accordance with the terms of the Warrant (the “ Stockholder Approval ”).  The Board shall (i) recommend to the Company’s stockholders the approval of the issuance of such shares to the Stockholder (the “ Board Recommendation ”), and (ii) include the Board Recommendation in the Company’s 2017 annual proxy statement.

(b) The Stockholder, and each of William C. Morris, Robert S. Rubin and Gary A. Kolstad (collectively, the “ Supporting Stockholders ”), irrevocably and unconditionally hereby agrees that at the Company’s 2017 annual meeting (and any adjourned or postponed meeting thereof), the Stockholder and each Supporting Stockholder shall, and shall cause all of its or his Affiliates that hold Voting Securities to, (i) appear at such meeting or otherwise cause all of their Voting Securities over which they have acquired Beneficial Ownership after the date hereof (including any Voting Securities acquired by means of purchase, dividend or distribution, any

3

stock options to acquire Common Stock or warrants or the conversion of any convertible securities or otherwise), which they own as of the applicable record date, to be counted as present thereat for purposes of calculating a quorum and (ii) vote or cause to be voted (including by proxy, if applicable) all such Voting Securities in favor of the Stockholder Approval.   Nothing contained in this Section 3(b) shall require the Stockholder, the Supporting Stockholders or any of their respective Affiliates to convert, exercise or exchange any option, warrants or convertible securities in order to obtain any underlying Voting Securities.

4. Representations and Warranties of the Stockholder.   The Stockholder represents and warrants to the Company as of the date hereof that:

(a) The Stockholder and its Affiliates are the sole record and Beneficial Owners of the Voting Securities set forth on Annex A opposite the Stockholder’s or such Affiliate’s name and such securities constitute all of the securities of the Company owned of record or Beneficially Owned by the Stockholder and its Affiliates.

Omnibus Incentive Plan or 2014 CARBO Ceramics Inc. Omnibus Incentive Plan, as the same may be amended from time to time, there are (A) no securities, options, warrants, calls, pre-emptive exchange, conversion, purchase or subscription rights, or other rights, agreements, arrangements or commitments of any kind, contingent or otherwise, that require the Company to issue, sell or otherwise cause to become outstanding, any shares of capital stock or other equity interest in the Company or require the Company to grant or enter into any such option, warrant, call, subscription, conversion, purchase or other right, agreement, arrangement or commitment, and no authorization has been given therefor, and (B) no commitments or agreements of any kind to which the Company or any subsidiary is bound obligating the Company to either (x) repurchase, redeem or otherwise acquire any shares of the Company’s capital stock or (y) accelerate the vesting or exercisability of any instrument referred to in clause (A) of this paragraph, as a result of entry into this Agreement either alone or upon the occurrence of any additional subsequent events.

6. Definitions.   Capitalized terms used but not otherwise defined in this Stockholder Agreement shall have the meanings ascribed to such terms in the Warrant.  As used in and for purposes of this Stockholder Agreement, the following terms have the following meanings:

“ Affiliate ” means, with respect to any Person, any Person directly or indirectly controlling, controlled by or under common control with, such other Person; provided, however , that the Company, any of its subsidiaries, or any of the Company’s other controlled Affiliates, in

6

each case, will not be deemed to be Affiliates of the Stockholder for purposes of this Stockholder Agreement.  For purposes of this definition, “control” (including, with correlative meanings, the terms “controlled by” and “under common control with”) when used with respect to any Person, means the possession, directly or indirectly, of the power to cause the direction of management or policies of such Person, whether through the ownership of voting securities, by contract or otherwise.

“ Beneficial Owner ” and words of similar import have the meaning assigned to such terms in Rule 13d-3 promulgated under the Exchange Act as in effect on the date of this Stockholder Agreement; provided , however , that for purposes of this Stockholder Agreement, a Person shall be deemed to be the beneficial owner of (i) any securities which may be acquired by such Person upon the exercise of any rights (irrespective of whether the right to acquire such securities is exercisable immediately or only after the passage of time, including the passage of time in excess of sixty (60) days, the satisfaction of any condition, the occurrence of any event or any combination of the foregoing) and (ii) any securities which are the subject of any Derivatives Contract (without regard to any short or similar position under the same or any other Derivatives Contract) to which such Person is a Receiving Party.  The term “ Beneficially Own ” has a meaning correlative to the foregoing.

“ Board ” means the Board of Directors of the Company or any duly authorized committee thereof.

“ Derivatives Contract ” means a contract between two parties (the “ Receiving Party ” and the counterparty) that is designed to produce economic benefits and risks to the Receiving Party and/or voting rights that correspond substantially to the ownership by the Receiving Party of a number of securities specified or referenced in such contract, regardless of whether obligations under such contract are required or permitted to be settled through delivery of cash, securities or other property.

“ Group ” has the meaning assigned to such term in Section 13(d)(3) of the Exchange Act.

“ Transfer ” by any Person means, with respect to any Voting Securities, directly or indirectly, to sell, transfer, assign, pledge, encumber, hypothecate or similarly dispose of, either voluntarily or involuntarily, the Voting Securities Beneficially Owned by such Person or of any interest (including any voting interest) in the Voting Securities Beneficially Owned by such Person; provided , however , that a Transfer shall not include (i) the exercise of the Warrant or (ii) the redemption or other acquisition of the Warrant by the Company.

(k) This Stockholder Agreement may be executed in two or more counterparts and delivered by facsimile, portable document format or other electronic transmission with the same effect as if all signatory parties had signed and delivered the same original document, each of which shall be deemed an original, but all of which together shall constitute one and the same instrument.

10

the parties hereto with respect to the subject matter hereof and supersede and preempt any prior understandings, agreements or representations by or among the parties, written or oral, that may have related to the subject matter hereof in any way.

(m) It is agreed that no delay or omission to exercise any right, power or remedy accruing to any party, upon any breach, default or noncompliance by another party under this Stockholder Agreement, shall impair any such right, power or remedy, nor shall it be construed to be a waiver of any such breach, default or noncompliance, or any acquiescence therein, or of or in any similar breach, default or noncompliance thereafter occurring.  It is further agreed that any waiver, permit, consent or approval of any kind or character on the part of any party hereto of any breach, default or noncompliance under this Stockholder Agreement or any waiver on such party’s part of any provisions or conditions of this Stockholder Agreement, must be in writing and shall be effective only to the extent specifically set forth in such writing.  All remedies, either under this Stockholder Agreement, by law or otherwise afforded to any party shall be cumulative and not alternative.

(n) Notwithstanding anything to the contrary in this Stockholder Agreement, in no event shall a party be liable under this Stockholder Agreement to any other party hereto or its representatives for (i) any exemplary or punitive damages or (ii) any special, consequential, incidental or indirect damages or lost profits, except in the case of clause (ii), to the extent any such damages or lost profits would otherwise be recoverable under applicable law in an action for breach of contract.

(o) In the event that one or more provisions of this Stockholder Agreement shall be deemed or held to be invalid, illegal or unenforceable in any respect under any applicable law, this Stockholder Agreement shall be construed with the invalid, illegal or unenforceable provision deleted, and the validity, legality and enforceability of the remaining provisions contained herein shall not be affected or impaired thereby.

(p) From time to time, as and when requested by a party hereto, the other parties hereto will execute and deliver, or cause to be executed and delivered, all such documents and instruments as may be reasonably necessary to consummate the transactions contemplated by this Stockholder Agreement.

(q) The Company and the Stockholder agree that the Company shall issue a press release, in form and substance reasonably acceptable to the Company and the Stockholder, announcing the transactions contemplated by the Credit Agreement, this Stockholder Agreement and the Warrant prior to the opening of the financial markets in New York City no later than the business day immediately after the date hereof.
