Without limiting the generality of any of the foregoing, to secure the prompt payment and performance to Agent and each Lender and each other holder of the Obligations, each Borrower hereby assigns, pledges and grants to Agent for its benefit and for the ratable benefit of each Lender a continuing security interest in and to and Lien on all of its ABL Equipment (including all ABL Equipment Spare Parts and all accessions (as defined in the Uniform Commercial Code) to the ABL Equipment) and all cash and non-cash proceeds thereof, whether now owned or existing or hereafter acquired or arising and wheresoever located. No Borrower has a commercial tort claim exceeding $500,000 as of the date hereof, except as set forth on Schedule 5.26 to the Credit Agreement. Each Borrower

hereby confirms and agrees that all security interests and Liens granted under the Credit Documents to Agent, for its benefit and for the ratable benefit of each Lender, Issuer and each other holder of any of the Obligations, continue in full force and effect and shall continue to secure the Obligations. All Collateral remains free and clear of any Liens other than Permitted Encumbrances. Nothing herein contained is intended to impair or limit in any manner the validity, priority and extent of Agent’s security interest in and Liens upon the Collateral.

8. Section Eight. Reaffirmation of Existing Financing Agreements. Except as modified by the terms hereof, all of the terms and conditions of the Credit Documents are hereby reaffirmed and shall continue in full force and effect as therein written. All references to the Credit Agreement shall mean the Credit Agreement as modified by all amendments heretofore executed and delivered and by this Amendment. Borrowers hereby acknowledge and agree it shall be an Event of Default under the Credit Agreement if (i) any representation or warranty made by any Borrower under or in connection with this Amendment shall have been untrue, false or misleading in any material respect when made, or (ii) Borrower shall fail to perform or observe any term, covenant or agreement contained in this Amendment.

9. Section Nine. Ratifications of Guaranty by ▇▇▇▇▇ Frac GP and Holdings. Holdings and ▇▇▇▇▇ Frac GP, each in its capacity as a “Guarantor” under the Guaranty, each by its signature below:

(a) Hereby acknowledges and agrees that the execution, delivery and performance of this Amendment by Borrowers, Agent and Lenders, and the carrying out of the provisions hereof and the consummation of all transactions contemplated hereunder, shall not affect or in any way diminish or modify the obligations of such Guarantor under the Guaranty, or under any other Credit Document to which such Guarantor is a party, and such Guarantor hereby acknowledges and reaffirms its obligations under the Guaranty, and under each other Credit Agreement to which Guarantor is a party.

(b) Hereby reconfirms and restates its grant under the Guaranty to Agent, for the ratable benefit of Agent, Issuer and each Lender and each other holder of the Obligations, of a continuing perfected Lien on and security interest in all of such Guarantor’s right, title and interest in and to the “Collateral” (as described in Section 8 of the Guaranty, as amended by this Amendment) to secure the payment and performance of the Obligations and such Guarantor’s obligations under the Guaranty, and hereby confirms that nothing herein, nor the execution, delivery and performance of this Amendment by Borrowers, Agent and Lenders, nor the carrying out of the provisions hereof nor the consummation of all transactions contemplated hereunder, shall impair or limit in any manner the validity, priority and extent of Agent’s security interest in and Liens upon such “Collateral”. Without limiting the generality of any of the foregoing, to secure the payment and performance of the Obligations and each Guarantor’s obligations under the Guaranty, each Guarantor grants to Agent, for itself and the ratable benefit of the Lenders and each other holder of the Obligations, a continuing perfected lien on and security interest in all of such Guarantor’s right, title and interest in and to all of its ABL Equipment (including all ABL Equipment Spare Parts and all accessions (as defined in the Uniform Commercial Code) to the ABL Equipment) and all cash and non-cash proceeds thereof, whether now owned or existing or hereafter acquired or arising and wheresoever located.

(c) Hereby acknowledges and agrees that the foregoing acknowledgements, agreements and reaffirmations are being given in an abundance of caution and for the avoidance of any doubt, and that nothing contained in the foregoing is intended to limit or contradict the provisions of any and all agreements and waivers contained in the Guaranty, specifically including, without limitation, the provisions, agreements and waivers of Section 2 of the Guaranty, and that the giving by such Guarantor of the foregoing acknowledgements, agreements and reaffirmations shall not be interpreted or construed under any circumstances as having established a course of dealing or course of conduct binding upon Agent and Lenders in the future or otherwise creating any future obligations on Agent and/or Lenders to obtain any similar acknowledgements, agreements and reaffirmations in connection with any future amendments to the Credit Agreement and the other Credit Documents.

(d) Hereby represents and warrants that each of the representations and warranties made by such Guarantor pursuant to the Guaranty and the Collateral Pledge Agreement dated July 8, 2011 by ▇▇▇▇▇ Frac GP in favor of PNC (the “GP Pledge Agreement”) are true and correct in all material respects on and as of the date hereof as if made on and as of the date hereof (except to the extent any such representation or warranty expressly relates only to any earlier and/or specified date, in which case such representation or warranty was materially true and correct in all respects on such date).

(e) Hereby represents and warrants that Guarantor is not in violation of any of the covenants and undertakings applicable to it set forth in the Guaranty (subject in each case to any notice, cure or grace period(s) applicable to such covenant or undertaking expressly provided for in the Guaranty (as applicable)).

10. Section Ten. Confirmation of Indebtedness and Release. Each Borrower, and each Guarantor by its signature below, hereby acknowledges, confirms and agrees that all of the Obligations (whether representing outstanding principal, accrued and unpaid interest, accrued and unpaid fees or any other Obligations of any kind or nature) currently owing by Borrowers under the Credit Agreement and the other Credit Documents, as reflected in the books and records of Agent and Lenders as of the date hereof, are unconditionally owing from and payable by Borrowers, and that Borrowers are indebted (jointly and severally) to Agent and Lenders with respect thereto, all without any set-off, deduction, counterclaim or defense. Each Borrower, and each Guarantor by its signature below, hereby acknowledges and agrees that it has no actual or potential claim or cause of action against Agent or any Lender relating to this Amendment (or any Amendments Documents), the Credit Agreement or any other Credit Document (including the Guaranty and the GP Pledge Agreement) and/or the Obligations arising thereunder or related thereto, in any such case arising on or before the date hereof. As further consideration for the consents and amendments set forth herein, each Borrower, and each Guarantor, by its signature below, hereby waives and releases and forever discharges Agent and Lenders, and the officers, directors, attorneys, agents and employees of each, from any liability, damage, claim, loss or expense of any kind originating in whole or in part known to Borrowers or Guarantor on or before the date of this Amendment that any Borrower or Guarantor may now have against Agent or Lenders or any of them arising out of or relating to the Obligations, this Amendment, the Credit Agreement or the Other Documents.

11. Section Eleven. Miscellaneous.

(a) No rights are intended to be created hereunder for the benefit of any third party, creditor or incidental beneficiary.

(b) The headings of any paragraph of this Amendment are for convenience only and shall not be used to interpret any provision hereof.

(c) No modification hereof or any agreement referred to herein shall be binding or enforceable unless in writing and signed on behalf of the party against whom enforcement is sought.

(d) This Amendment may be executed in any number of counterparts, each of which when so executed shall be deemed to be an original and all of which taken together shall constitute one and the same agreement. Delivery by facsimile or electronic transmission shall bind the parties hereto.

(e) This Amendment, and all matters relating hereto and arising herefrom, shall be governed by and construed in accordance with the laws of the State of New York applied to contracts to be performed wholly within the State of New York. The provisions of Section 16.1 of the Credit Agreement {agreements and consents to and waivers regarding jurisdiction, venue and service of process}, Section 16.5 of the Credit Agreement {indemnities}, Section 16.9 of the Credit Agreement {expenses}, Section 16.10 of the Credit Agreement {injunctive relief} and Article XII of the Credit Agreement {waivers (specifically including waivers of rights to jury trial)} are hereby incorporated by reference. If any part of this Amendment is contrary to, prohibited by, or deemed invalid under Applicable Laws or regulations, such provision shall be inapplicable and deemed omitted to the extent so contrary, prohibited or invalid, but the remainder hereof shall not be invalidated thereby and shall be given effect so far as possible. This Amendment (and the other Amendment Documents, if any), together with the Credit Agreement and other Credit Documents (each as amended or modified hereby), represents the entire agreement of the parties hereto regarding the matters covered hereby and thereby.

(f) This Amendment shall be binding upon and inure to the benefit of Borrowers, Guarantor, Agent, each Lender, all future holders of the Obligations and their respective successors and assigns, except that neither any Borrowers nor any Guarantor may assign or transfer any of its rights or obligations under this Amendment or the Credit Agreement or any other Credit Document without the prior written consent of Agent and each Lender.
