The ROFO Response shall set forth the terms and conditions (including, without limitation, the purchase price the Partnership proposes to pay for the ROFO Asset and the other terms of the purchase) pursuant to which the Partnership would be willing to enter into a binding agreement for the Proposed Transaction. If no ROFO Response is delivered by the Partnership within such 15-day period, then the Partnership shall be deemed to have waived its right of first offer with respect to such ROFO Asset, and the applicable Proppants Entity shall be free to enter into a Proposed Transaction with any third person on terms and conditions determined in the sole discretion of Proppants.

(b) If the Partnership submits a ROFO Response, the Partnership and Proppants shall negotiate, in good faith, the terms of the purchase and sale of the ROFO Asset for 10 days following the receipt of the ROFO Response by the Proppants Entity. If Proppants and the Partnership are unable to agree on such terms during such 10-day period, the Proppants Entity may Transfer the ROFO Asset to any third person on terms and conditions determined in the sole discretion of Proppants.

6.3 Entire Agreement. This Agreement constitutes the entire agreement of the Parties relating to the matters contained herein, superseding all prior contracts or agreements, whether oral or written, relating to the matters contained herein, other than the Contribution Agreement.

6.4 Termination. This Agreement, other than the provisions set forth in Section 2.7 and Articles 3, 4 and 6 hereof, shall terminate upon a Change of Control of the General Partner or the Partnership, other than any Change of Control of the General Partner or the Partnership deemed to have occurred pursuant to clause (d) of the definition of Change of Control solely as a result of a Change of Control of Proppants. Notwithstanding any other provision of this Agreement, if the General Partner is removed as general partner of the Partnership under circumstances where Cause does not exist and the Common Units held by the General Partner and its Affiliates are not voted in favor of such removal, this Agreement may immediately thereupon be terminated by Proppants.

6.5 Effect of Waiver or Consent. No waiver or consent, express or implied, by any Party to or of any breach or default by any Person in the performance by such Person of its obligations hereunder shall be deemed or construed to be a consent or waiver to or of any other breach or default in the performance by such Person of the same or any other obligations of such Person hereunder. Failure on the part of a Party to complain of any act of any Person or to declare any Person in default, irrespective of how long such failure continues, shall not constitute a waiver by such Party of its rights hereunder until the applicable statute of limitations period has run.

6.6 Amendment or Modification. This Agreement may be amended or modified from time to time only by the written agreement of all the Parties; provided, however, that the Partnership may not, without the prior approval of the Conflicts Committee, agree to any amendment or modification of this Agreement that the General Partner determines will adversely affect the holders of Common Units. Each such instrument shall be reduced to writing and shall be designated on its face an “Amendment” or an “Addendum” to this Agreement.

6.7 Assignment; Third Party Beneficiaries. Except as provided in Section 2.1, any Party shall have the right to assign its rights under this Agreement without the consent of any other Party, but no Party shall have the right to assign its obligations under this Agreement without the consent of the other Parties. Each of the Parties hereto specifically intends that each entity comprising the Proppants Entities and each entity comprising the Partnership Entities, as applicable, whether or not a Party to this Agreement, shall be entitled to assert rights and remedies hereunder as third-party beneficiaries hereto with respect to those provisions of this Agreement affording a right, benefit or privilege to any such entity.

6.8 Counterparts. This Agreement may be executed in two or more counterparts, and by facsimile, each of which shall be deemed to be an original, but all of which shall constitute one and the same agreement.

6.9 Severability. If any term or other provision of this Agreement is invalid, illegal or incapable of being enforced by any applicable rule of law or public policy, all other conditions and provisions of this Agreement shall nevertheless remain in full force and effect so long as the economic or legal substance of the transactions contemplated hereby is not affected in any manner materially adverse to any Party. Upon such determination that any term or other provision is invalid, illegal or incapable of being enforced, the Parties hereto shall negotiate in good faith to modify this Agreement so as to effect the original intent of the Parties as closely as possible in an acceptable manner to the end that transactions contemplated hereby are fulfilled to the extent possible.

6.10 Gender, Parts, Articles and Sections. Whenever the context requires, the gender of all words used in this Agreement shall include the masculine, feminine and neuter, and the number of all words shall include the singular and plural.

6.12 Withholding or Granting of Consent. Except as otherwise expressly provided in this Agreement, each Party may, with respect to any consent or approval that it is entitled to grant pursuant to this Agreement, grant or withhold such consent or approval in its sole and uncontrolled discretion, with or without cause, and subject to such conditions as it shall deem appropriate.

6.13 Laws and Regulations. Notwithstanding any provision of this Agreement to the contrary, no Party shall be required to take any act, or fail to take any act, under this Agreement if the effect thereof would be to cause such Party to be in violation of any applicable law, statute, rule or regulation.

6.14 Negation of Rights of Limited Partners, Assignees and Third Parties. Except as set forth in Section 6.7, the provisions of this Agreement are enforceable solely by the Parties, and no shareholder, limited partner, member, or assignee of Proppants, the General Partner, the Partnership or other Person shall have the right, separate and apart from Proppants, the General Partner or the Partnership, to enforce any provision of this Agreement or to compel any Party to comply with the terms of this Agreement.

6.15 No Recourse Against Officers and Directors. For the avoidance of doubt, the provisions of this Agreement shall not give rise to any right of recourse against any officer or director of any Proppants Entity or any Partnership Entity.

6.16 Arbitration.

Any dispute, controversy or claim arising out of or in connection with this Agreement shall be settled by final and binding arbitration conducted in Houston, Texas in accordance with the Commercial Arbitration Rules of the American Arbitration Association by one or more arbitrators designated in accordance with said Rules. All arbitrators must have not less than seven years experience in the energy industry. The Parties agree that the award of the arbitral tribunal (the “Arbitration Award”) shall be: (a) conclusive, final and binding upon the Parties; and (b) the sole and exclusive remedy between the Parties regarding any and all claims and counterclaims presented to the arbitral tribunal. All notices to be given in connection with the arbitration shall be as provided in Section 6.2 of this Agreement. The Arbitration Award shall include interest, at a rate determined as appropriate by the arbitrators, from the date of any breach or other violation of this Agreement to the date when the Arbitration Award is paid in full. The Arbitration Award shall also include the fixing of the expense of the arbitration and the assessment of the same, as is appropriate in the opinion of the arbitrators, against either or both Parties hereto. Each Party shall otherwise bear its cost for its respective legal fees, witnesses, depositions and other out-of-pocket expenses incurred in the course of the arbitration.

6.17 Dispute Resolution.

If the Parties are unable to resolve any service or performance issues or if there is a material breach of this Agreement that has not been corrected within thirty (30) days of receipt of notice of such breach, representatives of each of the Parties in dispute shall meet promptly to review and resolve such issues and breaches in good faith (the date on which such Persons first so meet, the “Discussion Date”). If such Persons are unable to fully resolve any such issues and breaches in good faith promptly after the Discussion Date, any remaining disputes shall be resolved in accordance with Section 6.16.
