SUBORDINATION TO SENIOR DEBT

(a)

General. Notwithstanding anything to the contrary in any document evidencing any Junior Debt, Junior Creditor agrees and covenants that the Junior Debt is and shall be subordinate in right of payment to the prior payment in full of the Senior Debt to the extent set forth in this Agreement. The Senior Debt shall not be deemed to have been paid in full until the Satisfaction of the Senior Debt.

(b)	Payment of Junior Debt. Until the Satisfaction of the Senior Debt, Junior Creditor shall not be entitled to receive any payments of principal, interest, fees or any other amounts payable from any Loan Party in respect of any Junior Debt.

3.2 Priority and Payment Over of Proceeds in Certain Events.

(a)

Insolvency or Dissolution of Loan Parties. Upon any payment or distribution of all or any of the assets or securities of any Loan Party of any kind or character, whether in cash, property or securities, upon any dissolution, winding up, liquidation, reorganization, arrangement, adjustment, protection, relief or composition of any Loan Party or its debts, whether voluntary or involuntary or in bankruptcy, insolvency, receivership, arrangement, reorganization, relief or other proceedings, or upon any assignment for the benefit of creditors or any other marshaling of the assets and liabilities of any Loan Party or otherwise (any such event being an "Insolvency Event"), all Senior Debt shall first be indefeasibly paid in full before Junior Creditor shall be entitled to receive any payment or other transfer in respect of any Junior Debt. Upon the occurrence of any Insolvency Event in respect of any Loan Party, any payment or distribution of assets or securities of such Loan Party of any kind or character, whether in cash, property or securities, to which Junior Creditor would be entitled except for the provisions of this Article III, shall be made by such Loan Party or by any receiver, trustee in bankruptcy, liquidating trustee, agent or other Person making such payment or distribution, directly to Senior Creditor for application (in the case of cash) to, or as collateral (in the case of non‑cash property or securities) for, the payment or prepayment in full of all Senior Debt.

(b)

Demand for or Acceleration of Payment of Junior Debt. If any Junior Debt is declared due and payable or the maturity thereof is accelerated for any reason, Senior Creditor shall be entitled to receive payment in full of all amounts due or to become due in respect of the Senior Debt (whether or not a default or event of default has occurred thereunder or such Senior Debt is or has been declared to be due and payable) before Junior Creditor shall be entitled to receive any payment or other transfer in respect of any Junior Debt.

(c)

Certain Payments Held in Trust. In the event that, notwithstanding the foregoing provisions prohibiting such payment or distribution, Junior Creditor receives any payment or distribution in respect of any Junior Debt in violation of the provisions of this Agreement, then and in such event such payment or distribution shall be received and held in trust for Senior Creditor and shall be paid over or delivered to Senior Creditor for application (in the case of cash) to, or as collateral (in the case of non‑cash property or securities) for, the payment or prepayment of all Senior Debt in full.

3.3 Suspension of Remedies. Until the Satisfaction of the Senior Debt, Junior Creditor shall not (a) ask, demand or sue for any payment or distribution or exercise any other remedy in respect of any Junior Debt (including any action to enforce any guaranty or other credit enhancement in respect of any Junior Debt or to enforce or exercise any rights or remedies under the Junior Note), or (b) commence, or join with any other creditor (other than Senior Creditor) in commencing, any Insolvency Event.

3.4 Rights of Senior Creditor Not to be Impaired; Modification of Senior Debt. No right of Senior Creditor to enforce subordination as herein provided shall at any time be prejudiced or impaired by any act or failure to act by Senior Creditor, or by any noncompliance by any Loan Party with the terms and provisions and covenants herein, regardless of any knowledge thereof Senior Creditor may have or otherwise be charged with. The provisions of this Article III are intended to be for the benefit of, and shall be enforceable directly by, Senior Creditor. Without limiting the generality of any provision of this Agreement, Junior Creditor agrees that Senior Creditor and each applicable Loan Party may from time to time modify the terms of any Senior Debt, including increasing the principal amount or adding types of indebtedness or other credit outstanding or available thereunder; extending or otherwise modifying the payment terms thereof; increasing or otherwise modifying the interest rates or fees payable thereunder; or extending the maturity thereof. Junior Creditor agrees that Senior Creditor and each such Loan Party may so modify the terms of any Senior Debt from time to time without obtaining the consent of, or giving notice to, Junior Creditor and that Senior Creditor's right to receive prior payment in full of the Senior Debt, as so modified, and all other rights of Senior Creditor hereunder, shall not be impaired or otherwise affected by any such modification or modifications.

3.5 Actions to Effectuate Subordination.

(a)

Authorization to Senior Creditor to Act. If an Insolvency Event occurs, Senior Creditor is irrevocably authorized and empowered (in its own name or in the name of Junior Creditor or otherwise), but shall have no obligation, to demand, sue for, collect and receive every payment or distribution referred to in Section 3.2(a) above and to file claims and proofs of claim with respect to the Junior Debt in any bankruptcy or other insolvency proceeding, and in each case to apply any payment or other distribution of assets or securities in the manner and to the extent provided in Section 3.2(a) above.

(b)

Specific Performance; Indemnification. Senior Creditor is entitled to specific performance of the provisions of this Agreement, at any time when Junior Creditor shall have failed to comply with any of the provisions of this Agreement. Junior Creditor hereby irrevocably waives any defense based on the adequacy of a remedy at Law that might be asserted as a bar to such remedy of specific performance. Junior Creditor acknowledges that the provisions of this Article III are intended to be enforceable at all times, whether before or after the commencement of an Insolvency Event. Junior Creditor shall indemnify, defend and hold harmless Senior Creditor for any losses, liabilities, taxes, claims, debts, damages, judgments, settlements, costs, fines, expenses (including attorneys' fees), penalties or other obligations incurred by Senior

Creditor based upon, arising out of or otherwise relating to (i) any breach of any representation or warranty of Junior Creditor set forth in this Agreement or (ii) any breach of any covenant or obligation of Junior Creditor set forth in this Agreement.

3.6 Subordination Legend; Further Assurances.

(a)	Junior Debt. Junior Creditor will cause each instrument now or hereafter held by or on behalf of Junior Creditor evidencing any Junior Debt to contain, in a conspicuous manner, the following legend:

THE INDEBTEDNESS EVIDENCED BY THIS INSTRUMENT IS SUBORDINATE TO THE PRIOR PAYMENT IN FULL OF CERTAIN SENIOR DEBT (AS DEFINED IN THE SUBORDINATION AGREEMENT HEREINAFTER REFERRED TO) PURSUANT TO, AND TO THE EXTENT PROVIDED IN, THAT CERTAIN SUBORDINATION AGREEMENT DATED AS OF JUNE 27, 2016 IN FAVOR OF KOCH MINERALS, LLC, AS THE SAME MAY BE AMENDED, RESTATED, CONSOLIDATED, REPLACED OR OTHERWISE MODIFIED FROM TIME TO TIME. THIS INSTRUMENT MAY NOT BE OFFERED, SOLD OR OTHERWISE TRANSFERRED UNTIL THE PURCHASER, ASSIGNEE OR TRANSFEREE HAS BECOME A PARTY TO AND BOUND BY SUCH SUBORDINATION AGREEMENT.

(b)

Further Assurances. Junior Creditor will further mark Junior Creditor's books of account, if any, in such a manner as shall be effective to give proper notice of the effect of this Agreement, and will, in the case of any Junior Debt which is not evidenced by any instrument, upon Senior Creditor's request cause such Junior Debt to be evidenced by an appropriate instrument or instruments endorsed with the above legend. Junior Creditor will, at Junior Creditor's expense and at any time and from time to time, promptly execute and deliver all further instruments and documents, and take all commercially reasonable further action, that may be necessary or desirable, or that Senior Creditor may request, in order to protect any right or interest granted or purported to be granted hereby or to enable Senior Creditor to exercise and enforce its rights and remedies hereunder.

3.7 Miscellaneous.

(a)

All rights and interests of Senior Creditor under this Agreement, and all agreements and obligations of Junior Creditor under this Agreement, shall remain in full force and effect irrespective of: (i) any lack of validity or enforceability of instruments or agreements evidencing or otherwise relating to any Senior Debt; (ii) any change in the time, manner or place of payment of, or in any other term of, any Senior Debt, or any other amendment or waiver of or any consent to departure from any instruments or agreements evidencing or otherwise relating to any Senior Debt; (iii) any exchange, release or non‑perfection of any collateral, any release of any Person liable in whole or in part, or any release or amendment or waiver of or consent to departure from any guaranty, for any Senior Debt; or (iv) any other circumstance that might otherwise constitute a defense available to, or a discharge of, a surety.

(b)

The provisions of this Article III shall continue to be effective or be reinstated, as the case may be, if at any time any payment of any Senior Debt is rescinded or must otherwise be returned by Senior Creditor upon the insolvency, bankruptcy or reorganization of any Loan Party or otherwise, all as though such payment had not been made.

(c)

Junior Creditor hereby waives promptness, diligence, notice of acceptance and any other notice with respect to any Senior Debt and this Article III and any requirement that Senior Creditor protect, secure, perfect or insure any security interest or lien or any property subject thereto or exhaust any right or take any action against any Loan Party or any other Person or any collateral.

(d)

No failure on the part of Senior Creditor to exercise, and no delay in exercising, any right hereunder shall operate as a waiver thereof; nor shall any single or partial exercise of any right hereunder preclude any other or further exercise thereof or the exercise of any other right. The remedies herein provided are cumulative and not exclusive of any remedies provided by Law or equity.

(e)

The provisions of this Article III, and all other provisions of this Agreement, constitute a continuing agreement and shall (i) remain in full force and effect until the Satisfaction of the Senior Debt, (ii) be binding upon Junior Creditor and Junior Creditor's successors, permitted assigns, heirs and personal representatives, as applicable, and (iii) inure to the benefit of and be enforceable by Senior Creditor and its successors and assigns. Without limiting the generality of the foregoing clause (iii), Senior Creditor may assign or otherwise transfer its rights under this Agreement to any other Person, and such other Person shall thereupon become vested with all such rights granted to Senior Creditor herein or otherwise. Notwithstanding anything to the contrary herein, no Junior Creditor may assign or otherwise transfer this Agreement to any other Person without the prior written consent of Senior Creditor. Any purported assignment or transfer by Junior Creditor in violation of this Agreement will be null and void.

ARTICLE IV
COVENANTS

4.1 Covenants of Junior Creditor. Junior Creditor covenants and agrees with Senior Creditor that, unless Senior Creditor shall otherwise agree in writing, until the Satisfaction of the Senior Debt:

(a)

Junior Creditor will not cancel or otherwise discharge any Junior Debt (except upon payment in full thereof to the extent permitted by Article III) without the prior written consent of Senior Creditor, which consent shall not be unreasonably withheld so long as no Insolvency Event has occurred and is continuing.

(b)	Junior Creditor will not sell, assign, pledge, encumber or otherwise dispose of any Junior Debt held by Junior Creditor unless each such sale, assignment, pledge, encumbrance or disposition is made expressly subject to this Agreement.

(c)

Junior Creditor will not permit the terms of any Junior Debt held by Junior Creditor to be amended or otherwise modified in any respect without obtaining the prior written consent of Senior Creditor. Similarly, Junior Creditor will not permit the Junior Note to be amended or otherwise modified in any respect without obtaining the prior written consent of Senior Creditor.

(d)

Junior Creditor will not secure the payment of any Junior Debt, or obtain a lien, security interest or other charge or encumbrance of any nature whatsoever against any Loan Party's property, whether now owned or hereafter acquired; and, notwithstanding the foregoing, should Junior Creditor have or obtain at any time any lien, security interest or other charge or encumbrance of any nature whatsoever (including any judgment lien) against any property of any Loan Party, such lien, security interest or other charge or encumbrance shall be in all respects subject, junior and subordinate to all liens, security interests or other charges or encumbrances of any nature whatsoever (including any judgment lien) at any time granted or suffered by such Loan Party in favor of Senior Creditor, and without regard to the method or manner of creation, attachment or perfection of any such liens, security interests or other charges and encumbrances and without regard to the order of filing of any Uniform Commercial Code financing statements, mortgages or other lien perfection documents or the issuance or recordation of any judgment liens.

(e)

Junior Creditor will not accept or be the beneficiary under any guaranty, debt purchase agreement or similar assurance of payment or performance from any Person who has guaranteed or hereafter guarantees any Senior Debt, or who is or hereafter becomes a co-borrower under any Senior Debt, or who otherwise has assured or hereafter assures payment of any Senior Debt, in each case without obtaining the prior written consent of Senior Creditor, and then only upon first entering into a subordination agreement with Senior Creditor whereby Junior Creditor's payment and other rights in respect of such guarantor, co-borrower or other obligor are subordinated in substantially the same manner as Junior Creditor's payment and other rights in respect of the Loan Parties are subordinated under this Agreement. If, notwithstanding the foregoing, Junior Creditor fails to enter into such subordination agreement, all payment, lien and other rights of Junior Creditor with respect to such guarantor, co-borrower or other obligor shall nonetheless be subject, junior and subordinate to all payment, lien and other rights of Senior Creditor with respect to such guarantor, co-borrower or other obligor.

ARTICLE V
MISCELLANEOUS

5.1 Amendments; Waiver.

5.2 Severability. If any provision of this Agreement or the application of any provision of this Agreement to any Party or circumstance is, to any extent, adjudged invalid or unenforceable, the application of the remainder of such provision to such Party or circumstance, the application of such provision to the other Party or other circumstances, and the application of the remainder of this Agreement shall not be affected thereby.
