Section 1.3 Consideration for the Properties .

(a) The aggregate consideration for the purchase and sale of the Properties shall be (a) an amount of Common Units equal to the quotient obtained by dividing (i) the amount equal to one-half of the Total Consideration Value by (ii) the average closing price of a Common Unit on the NASDAQ Global Select Market during the period beginning on the date that is fifteen (15) trading days immediately prior to the Closing Date and ending on the date that is two (2) trading days immediately prior to the Closing Date (the “ Subject Units ”) and (b) cash in the amount equal to one-half of the Total Consideration Value (the “ Cash Purchase Price ”), subject to adjustment according to the terms and conditions of this Agreement, which shall be paid in cash by wire transfer to such account as is directed by the Contributor.

Section 1.5 Due Diligence, Title Defects and Adjustments to the Total Consideration Value .

(a) Inspection and Assertion of Defects.

(i) The Contributor shall make available to the Partnership all title opinions, supplemental title opinions and other title information relating to the Properties and in the possession of the Contributor or to which the Contributor has access. The Partnership may, to the extent it deems appropriate, conduct, at its sole cost, such title examination or investigation as it may choose to conduct with respect to the Properties. If any matter comes to the Partnership’s attention which would constitute a “Defect” (as below defined), the Partnership may notify the Contributor of such Defect (the “ Defect Notice ”) on or before 6:00 pm Dallas time on June 28, 2017 (the “ Defect Deadline ”); provided, however, that the Partnership agrees that it shall furnish the Contributor once every one (1) week until the Defect Deadline with a preliminary Defect Notice. Such Defects of which the Partnership so provides notice are herein called “ Asserted Defects .” The Defect Notice shall contain (i) a description of the Asserted Defect, (ii) the Property on Exhibit A affected by the Asserted Defect, (iii) the number of net mineral acres or net royalty acres, as applicable, affected by the Asserted Defect, (iv) supporting documents reasonably necessary for the Contributor (as well as any title attorney or examiner hired by the Contributor) to verify the existence or an extent of the Asserted Defect, and (v) the amount by which the Partnership reasonably believes the Allocated Value of such Property is decreased by the Asserted Defect. If the Partnership notifies the Contributor of

Asserted Defects, the Contributor shall have the option to cure such Asserted Defects on or before Closing. NOTWITHSTANDING ANY OTHER PROVISION OF THIS AGREEMENT TO THE CONTRARY, THE PARTNERSHIP SHALL BE DEEMED TO HAVE WAIVED ITS RIGHT TO ASSERT DEFECTS OF WHICH THE CONTRIBUTOR HAS NOT BEEN GIVEN NOTICE ON OR BEFORE THE DEFECT DEADLINE. For purposes hereof, the “ Allocated Value ” shall mean the Allocated Value of each Property that the Parties hereto have mutually agreed, which is set forth on Exhibit A .

(ii) The term “ Defect ” as used in this Section shall mean, except for and subject to the Permitted Encumbrances and the terms and provisions of the Basic Documents and contracts pursuant to Section 1.1(b) , the following:

(A) Net Royalty Acres or Net Mineral Acre Variances . The Contributor’s ownership of the Properties is such that, with respect to a Property listed on Exhibit A hereto, it entitles the Contributor to no fewer net mineral acres or net royalty acres that that specified in Exhibit A in the columns entitled “Net Mineral Acres” or “Net Royalty Acres”;

(B) Liens . The Contributor’s ownership of a Property is subject to a lien; or

(C) Preferential Rights . The Contributor’s ownership of a Property is subject to a preferential right to purchase such property or a requirement that consent to assignment of such Property be obtained, unless a waiver of such right has been obtained with respect to the transaction contemplated hereby or, in the case of a preferential right to purchase, an appropriate tender of the applicable interest has been made to the party holding such right and the period of time required for such party to exercise such right has expired without such party exercising such right.

(b) Certain Price Adjustments . If, as a part of the due diligence review provided for in Section 1.5(a) above, Asserted Defects are presented to the Contributor and the Contributor does not cure such Asserted Defects prior to Closing, then the Partnership may elect to do one of the following with respect to each Property affected by one or more Asserted Defects (a “ Defect Property ”):

(i) Exclude such Defect Property at the Closing, in which event the Total Consideration Value shall be reduced by an amount equal to the allocated value thereof as shown on Exhibit A . If any Defect Properties are excluded by the Partnership at the Closing, then such Defect Properties shall not be conveyed to the Partnership at Closing.

(ii) Convey such Defect Property at Closing and adjust the Total Consideration Value as follows:

(A) if a Defect is of the type described in Section 1.5(a)(ii)(A) above, then the Total Consideration Value shall be reduced by an amount determined by multiplying the Allocated Value of such Property set forth on Exhibit A by a fraction, the numerator of which is the reduction in the net mineral acres or net royalty acres, as applicable, and the denominator of which is the net mineral acres or net royalty acres specified for such Property on Exhibit A , as applicable;

(B) if a Defect is a lien, encumbrance or other charge upon a Defect Property which is liquidated in amount, then the Total Consideration Value shall be reduced by the sum necessary to be paid to the obligee to remove the Defect from the affected Defect Property; and

(C) if a Defect represents an obligation or burden upon the affected Defect Property for which the economic detriment to the Property is not calculable or liquidated as set forth above in Section 1.5(b)(ii)(A) or Section 1.5(b)(ii)(B) , the Total Consideration Value shall be reduced by the amount that the Contributor and the Partnership mutually agree upon as reasonable to compensate the Partnership for the adverse economic effect that such Defect has on the Defect Property; provided that if such Defect is reasonably susceptible of being cured, the reduction in Total Consideration Value shall not be greater than the lesser of (1) the reasonable cost and expense of curing such Defect or (2) the share of such curative work cost and expense which is allocated to the Defect Property hereunder.

Section 1.6 Special Warranty of Title .

(a) Except for the special warranty of title set forth herein, the Contributor makes NO WARRANTY OR REPRESENTATION, EXPRESS, IMPLIED, STATUTORY OR OTHERWISE, WITH RESPECT TO THE CONTRIBUTOR’S TITLE TO ANY OF THE PROPERTIES AND THE PARTNERSHIP HEREBY ACKNOWLEDGES AND AGREES THAT THE PARTNERSHIP’S SOLE REMEDY FOR ANY DEFECT OF TITLE, INCLUDING ANY TITLE DEFECT, WITH RESPECT TO ANY OF THE ASSETS SHALL BE PURSUANT TO THE PROCEDURES SET FORTH IN SECTION 1.5 .

(b) If the Closing occurs, then effective as of the Reference Date, the Contributor warrants that the Properties shall be conveyed to the Partnership without Defect against every Person whomsoever lawfully claiming by, through and under the Contributor, but not otherwise, subject, however, to the Permitted Encumbrances.

(c) Notwithstanding anything herein to the contrary, if an Asserted Defect under Section 1.5 results from a matter which could also result in the breach of any the special warranty of title set forth in this Section 1.6 , the Partnership shall be precluded from also asserting such matters as the basis of the breach of such representation or warranty of Contributor.

Section 1.7 Tax Treatment . The Contributor and the Partnership agree that the transactions contemplated by this Agreement shall be treated for all federal and applicable state income Tax purposes as a sale to the extent of the Cash Purchase Price received by the Contributor, and as a contribution to capital under Section 721(a) of the Code to the extent of the Subject Units received by the Contributor pursuant to Treasury Regulation Section 1.707-3 (the “ Tax Treatment ”). The Contributor and the Partnership agree to file all Tax Returns in a manner consistent with the Tax Treatment, and neither the Contributor nor the Partnership shall take, or shall permit any Affiliate to take, any position inconsistent with such Tax Treatment on any Tax Return or otherwise, unless required to do so by Applicable Law or a “determination” within the meaning of Code Section 1313(a)(1).

(c) Apportionment of Taxes . The Contributor shall bear all Taxes for any Pre-Closing Tax Period, and the Partnership shall bear all Taxes for any Post-Closing Tax Period. If any Tax (or Tax refund) relates to a period that begins before and ends after the Closing Date, the Contributor and the Partnership shall use the following conventions for determining the portion of such Tax (or Tax refund) that relates to a Pre-Closing Tax Period and which relates to a Post-Closing Tax Period: (A) production Taxes that are attributable to the severance or production of hydrocarbons shall be deemed allocated to the period in which the relevant severance or production occurred; (B) in the case of Property Taxes and other similar Taxes imposed on a periodic basis, the amount of such Taxes (or Tax refunds) attributable to the Pre-Closing Tax Period shall be determined by multiplying such Taxes for the entire period by a fraction, the numerator of which is the number of calendar days in the portion of the period ending on the Closing Date and the denominator of which is the number of calendar days in the entire period, and the remaining amount of such Taxes (or Tax refunds) shall be attributable to the Post-Closing Tax Period; and (C) in the case of all other Taxes, the amount of Taxes (or Tax refunds) attributable to the Pre-Closing Tax Period shall be determined as if a separate return was filed for the period ending as of the end of the day on the Closing Date using a “closing of the books methodology,” and the remaining amount of the Taxes (or Tax refunds) for such period shall be attributable to the Post-Closing Tax Period; provided, however, that for purposes of clause (C), exemptions, allowances, or deductions that are calculated on an annual basis (including depreciation and amortization deductions) shall be apportioned between the Pre-Closing Tax Period and the Post-Closing Tax Period in proportion to the number of days in each such period. For the avoidance of doubt, the Contributor shall bear (X) all income Taxes attributable to the Properties for all Pre-Closing Tax Periods and (Y) all income Taxes imposed by Applicable Law on the Contributor or its direct or indirect owners resulting from the transactions contemplated by this Agreement.

(d) Tax Returns . The Contributor shall be responsible for the preparation and timely filing of any Tax Returns with respect to Taxes required to be filed before the Closing Date. The Partnership shall be responsible for the preparation and timely filing of any Tax Returns with respect to Taxes required to be filed on or after the Closing Date.

(e) Tax Refunds . All refunds or credits for Taxes for any Excluded Tax and for any Transfer Tax shall be for the sole benefit of the Contributor; provided, however, that to the extent the Partnership incurs an Excluded Tax or Transfer Tax and is not indemnified for such Excluded Tax or Transfer Tax, refunds or credits of such Excluded Tax or Transfer Tax shall be for the sole benefit of the Partnership. To the extent that the Partnership receives a refund or

credit that is for the benefit of the Contributor, the Partnership shall promptly pay such refund or the value of the credit (net of all out of pocket expenses and costs and Taxes incurred in obtaining such refund) to the Contributor. All refunds or credits for Taxes relating to the Properties for a Post-Closing Tax Period that are not Excluded Taxes shall be for the sole benefit of the Partnership. To the extent that the Contributor receives a refund or credit for a Tax that is for the benefit of the Partnership, the Contributor shall promptly pay such refund or the value of the credit (net of all reasonable out of pocket expenses and costs and Taxes incurred in obtaining such refund) to the Partnership.

(f) Tax Cooperation . The Partnership and the Contributor shall (i) assist in the preparation and timely filing of any Tax Return (including any claim for a Tax refund) relating to the Properties; (ii) assist in any audit or other proceeding with respect to Taxes or Tax Returns relating to the Properties; (iii) make available any information, records, or other documents relating to any Taxes or Tax Returns relating to the Properties; (iv) provide any information required to allow the other party to comply with any information reporting or withholding requirements contained in the Code or other applicable Tax Laws; and (v) provide certificates or forms, and timely execute any Tax Return that are necessary or appropriate to establish an exemption for (or reduction in) any Transfer Tax. Without limiting the foregoing, on or prior to the Closing, the Contributor shall provide to the Partnership a schedule that sets forth the adjusted tax basis in each Contributed Asset (as determined immediately prior to Closing) (the “ Tax Basis Schedule ”).

(g) Allocation of the Cash Purchase Price . The Contributor and the Partnership agree that for all federal and state income Tax purposes, the Cash Purchase Price shall be allocated by the Partnership among the portion of the Properties purchased from the Contributor in accordance with Section 1060 of Code and the Treasury Regulations. The Partnership shall prepare the Form 8594 to be attached hereto as Schedule 7.4(g) (the “ Final Allocation Statement ”) in a manner consistent with Section 1060 of the Code and the Treasury Regulations thereunder. The Contributor and the Partnership agree to report in accordance with the allocations set forth in the Final Allocation Statement in any relevant Tax Returns or Tax filings (including Internal Revenue Service Form 8594 and any other forms or reports required to be filed pursuant to Section 1060 of the Code or any provision of local or state law) (“ 1060 Forms ”), and in the course of any Tax claim, except as otherwise required by Applicable Law, and to cooperate in the preparation of any 1060 Forms in the manner required by Applicable Law. In any action relating to any Tax, neither the Contributor nor the Partnership shall contend or represent that any of the allocations set forth in the Final Allocation Statement is not correct. If any Taxing authority disputes the Final Allocation Statement reflected by the Contributor or the Partnership on their respective Tax Returns, the Contributor or the Partnership, as the case may be, shall promptly notify the other party in writing of the items in dispute.

(h) Like-Kind Exchange . Notwithstanding anything else in this Agreement to the contrary, the Contributor shall have the right to structure the transactions contemplated under the terms of this Agreement as a Like-Kind Exchange to the extent treated as a sale pursuant to Section 1.7 . Notwithstanding any other provisions of this Agreement, in connection with effectuating a Like-Kind Exchange, the Contributor shall have the right, at or prior to the Closing Date, to assign all or a portion of its right to receive the Cash Purchase Price under this Agreement (the “ Assigned Rights ”) to a “qualified intermediary” (as that term is defined in Treasury Regulation § 1.1031(k)-1(g)(4)) or to a “qualified exchange accommodation titleholder” (as that term is defined in U.S. Revenue Procedure 2000-37). In the event the Contributor assigns the Assigned Rights to a “qualified intermediary” pursuant to this Section 7.4(h) , then the Contributor agrees to notify the Partnership in writing of such assignment reasonably in advance of the Closing Date. In addition, should the Contributor choose to effectuate a Like-Kind Exchange, the parties agree to use commercially reasonable efforts to cooperate with one another in the completion of such an exchange, including the execution of all documents reasonably necessary to effectuate such a Like-Kind Exchange; provided, however, that (a) the Closing Date shall not be delayed or affected by reason of the Like-Kind Exchange, (b) the Contributor shall effect its Like-Kind Exchange through an assignment of the Assigned Rights to a “qualified intermediary” or to a “qualified exchange accommodation titleholder,” but such assignment shall not release the Contributor from any of its liabilities or obligations under this Agreement and (c) the Partnership shall incur no additional costs, expenses, fees or damages as a result of or in connection with the exchange requested by the Contributor. The Partnership, by its consent to a Like-Kind Exchange by the Contributor, shall not be responsible in any way for the Contributor’s compliance with the rules applicable to any Like-Kind Exchange.

Section 7.5 Casualty Loss . If any Casualty Loss occurs prior to the Closing, the Contributor shall (a) transfer the affected Property to the Partnership at Closing, notwithstanding such Casualty Loss, (b) transfer all unpaid insurance proceeds, claims, awards, and other payments arising out of such Casualty Loss to the Partnership and (c) transfer to the Partnership an amount equal to all cash sums, if any, paid to the Contributor prior to Closing as insurance proceeds, awards or other payments arising out of such Casualty Loss.

Section 9.2 Indemnification .

(a) Subject to Section 9.1 , the Contributor hereby agrees to indemnify, defend and hold the Partnership and its Affiliates and their respective directors, managers, officers, employees, stockholders, unitholders, members, partners, agents, attorneys, representatives, successors and assigns (collectively, the “ Partnership Indemnified Parties ”) harmless from and against, and pay to the applicable Partnership Indemnified Parties the amount of, any and all losses, liabilities, claims, obligations, deficiencies, demands, judgments, damages (including incidental and consequential damages), interest, fines, penalties, claims, suits, actions, causes of action, assessments, awards, costs and expenses (including reasonable costs of investigation and defense and attorneys’ and other professionals’ fees and the cost of enforcing any right to indemnification hereunder), or any diminution in value, whether or not involving a third party claim (individually, a “ Loss ” and, collectively, “ Losses ”):

(iv) the Excluded Properties.

(b) Subject to Section 9.1 , the Partnership hereby agrees to indemnify, defend and hold the Contributor and its Affiliates and their respective stockholders, unitholders, directors, managers, employees, members, partners, agents, attorneys, representatives, successors and permitted assigns (collectively, the “ Contributor’s Indemnified Parties ”) harmless from and against, and pay to the applicable the Contributor’s Indemnified Parties the amount of, any and all Losses:

(c) The right to indemnification or any other remedy based on representations, warranties, covenants and agreements in the Transaction Documents shall not be affected by any investigation conducted at any time, or any Knowledge acquired (or capable of being acquired) at any time, whether before or after the execution and delivery of this Agreement or the Closing Date, with respect to the accuracy or inaccuracy of or compliance with, any such representation, warranty, covenant or agreement. The waiver of any condition based on the accuracy of any representation or warranty, or on the performance of or compliance with any such covenant or agreements, will not affect the right to indemnification or any other remedy based on such representations, warranties, covenants and agreements. The remedy of indemnification set forth in this ARTICLE 9 shall be in addition to any other remedies that any indemnified party may have under Applicable Laws (whether asserted in a proceeding at law or in equity).

Section 9.3 Indemnification Procedures .

(a) A claim for indemnification for any matter not involving a third party claim may be asserted by notice to the party from whom indemnification is sought; provided that failure to so notify the indemnifying party shall not preclude the indemnified party from any indemnification which it may claim in accordance with this ARTICLE 9 .

(b) If any indemnified party receives notice of the assertion or commencement of any action made or brought by any Person who is not a party to this Agreement or an Affiliate of a party to this Agreement or a representative of the foregoing (a “ Third Party Claim ”) against such indemnified party with respect to which the indemnifying party is obligated to provide indemnification under this Agreement, the indemnified party shall give the indemnifying party reasonably prompt written notice thereof, but in any event not later than thirty (30) calendar days after receipt of such notice of such Third Party Claim. The failure to give such prompt written notice shall not, however, relieve the indemnifying party of its indemnification obligations, except and only to the extent that the indemnifying party forfeits rights or defenses by reason of such failure. The indemnifying party shall have the right to participate in, or by giving written notice to the indemnified party, to assume the defense of any Third Party Claim at the indemnifying party’s expense and by the indemnifying party’s own

counsel, and the indemnified party shall cooperate in good faith in such defense; provided, that if the indemnifying party is the Contributor, such indemnifying party shall not have the right to defend or direct the defense of any such Third Party Claim that seeks an injunction or other equitable relief against the indemnified party. In the event that the indemnifying party assumes the defense of any Third Party Claim, subject to Section 9.3(c) , it shall have the right to take such action as it deems necessary to avoid, dispute, defend, appeal or make counterclaims pertaining to any such Third Party Claim in the name and on behalf of the indemnified party. The indemnified party shall have the right to participate in the defense of any Third Party Claim with counsel selected by it subject to the indemnifying party’s right to control the defense thereof. The fees and disbursements of such counsel shall be at the expense of the indemnified party, provided, that if in the reasonable opinion of counsel to the indemnified party, (A) there are legal defenses available to an indemnified party that are different from or additional to those available to the indemnifying party; or (B) there exists a conflict of interest between the indemnifying party and the indemnified party that cannot be waived, the indemnifying party shall be liable for the reasonable fees and expenses of counsel to the indemnified party in each jurisdiction for which the indemnified party determines counsel is required. If the indemnifying party elects not to compromise or defend such Third Party Claim, fails to promptly notify the indemnified party in writing of its election to defend as provided in this Agreement, or fails to diligently prosecute the defense of such Third Party Claim, the indemnified party may, subject to Section 9.3(c) , pay, compromise, defend such Third Party Claim and seek indemnification for any and all Losses based upon, arising from or relating to such Third Party Claim.

(c) Notwithstanding any other provision of this Agreement, the indemnifying party shall not enter into settlement of any Third Party Claim without the prior written consent of the indemnified party, except as provided in this Section 9.3(c) . If a firm offer is made to settle a Third Party Claim without leading to liability or the creation of a financial or other obligation on the part of the indemnified party and provides, in customary form, for the unconditional release of each indemnified party from all liabilities and obligations in connection with such Third Party Claim and the indemnifying party desires to accept and agree to such offer, the indemnifying party shall give written notice to that effect to the indemnified party. If the indemnified party fails to consent to such firm offer within ten (10) days after its receipt of such notice, the indemnified party may continue to contest or defend such Third Party Claim and in such event, the maximum liability of the indemnifying party as to such Third Party Claim shall not exceed the amount of such settlement offer. If the indemnified party fails to consent to such firm offer and also fails to assume defense of such Third Party Claim, the indemnifying party may settle the Third Party Claim upon the terms set forth in such firm offer to settle such Third Party Claim. If the indemnified party has assumed the defense pursuant to Section 9.3(b) , it shall not agree to any settlement without the written consent of the indemnifying party (which consent shall not be unreasonably withheld or delayed).
