of Merger”) with the Secretary of State of the State of Delaware (the “Delaware Secretary of State”) in such form as required by, and executed in accordance with the relevant provisions of, the DLLCA and the DRULPA. The Merger shall become effective at such time as the Certificate of Merger is filed with the Delaware Secretary of State or at such subsequent time as the Partnership and Contango shall agree in writing and as shall be specified in the Certificate of Merger (the date and time the Merger becomes effective being the “Effective Time”).

(c) At the Effective Time, the effect of the Merger shall be as provided in the applicable provisions of the DLLCA and the DRULPA. Without limiting the generality of the foregoing, at the Effective Time, all the property, rights, privileges, powers and franchises of the Partnership and Michael Merger Sub shall vest in Surviving Entity, and all debts, liabilities and duties of the Partnership and Michael Merger Sub shall become the debts, liabilities and duties of Surviving Entity, all as provided in the applicable provisions of the DLLCA and the DRULPA.

Section 1.2 Closing. The closing of the Merger (the “Closing”) shall take place at 10:00 a.m., Central Time, on the third Business Day following the satisfaction or, to the extent permitted by applicable Law, waiver of the conditions set forth in Article VI (other than those conditions that by their terms are to be satisfied at the Closing, but subject to the satisfaction or, to the extent permitted by applicable Law, waiver of those conditions), at the offices of Gibson, Dunn & Crutcher LLP, 811 Main Street, Suite 3000, Houston, Texas 77002, unless another date, time or place is agreed to in writing by Contango and the Partnership. The date on which the Closing occurs is referred to in this Agreement as the “Closing Date.”

Section 1.3 Governing Documents; Officers.

(a) Governing Documents of Surviving Entity. At the Effective Time, by virtue of the Merger, the certificate of formation and limited liability company agreement of Michael Merger Sub as in effect immediately prior to the Effective Time shall be the certificate of formation and limited liability company agreement, respectively, of Surviving Entity as of and after the Effective Time (until thereafter amended as provided therein or by applicable Law).

(b) Officers of Surviving Entity. The persons who are the officers of Michael Merger Sub immediately prior to the Effective Time shall be the officers and hold the same offices of Surviving Entity effective as of the Effective Time, each such person to hold office in accordance with the Governing Documents of Surviving Entity.

ARTICLE II

EFFECT ON THE CAPITAL STOCK OF THE CONSTITUENT ENTITIES

Section 2.1 Conversion of Capital Securities.

(a) Merger. At the Effective Time, by virtue of the Merger and without any action on the part of any party hereto or the holders of any equity interests in Michael Merger Sub or the Partnership:

(i) Each Partnership Common Unit issued and outstanding immediately prior to the Effective Time (other than any Partnership Common Units to be cancelled pursuant to Section 2.1(a)(iv)) shall be converted into the right to receive 1.7500 (the

“Partnership Common Unit Exchange Ratio”) shares of validly issued, fully paid and nonassessable common stock, par value $0.04 per share, of Contango (“Contango Common Stock” and such consideration, the “Merger Consideration”). All such Partnership Common Units that were issued and outstanding immediately prior to the Effective Time shall no longer be outstanding and shall automatically be cancelled and retired and shall cease to exist, and each holder of a certificate or certificates which immediately prior to the Effective Time represented any Partnership Common Units or book-entry units which immediately prior to the Effective Time represented Partnership Common Units shall thereafter cease to have any rights with respect to such Partnership Common Units, except the right to receive the Merger Consideration, any dividends or distributions payable pursuant to Section 2.3(e), any cash in lieu of fractional shares of Contango Common Stock payable pursuant to Section 2.3(g) and as provided by Law.

(ii) The Partnership GP Interest issued and outstanding immediately prior to the Effective Time shall no longer be outstanding and shall automatically be cancelled and retired and shall cease to exist.

(iii) The membership interests of Michael Merger Sub issued and outstanding immediately prior to the Effective Time shall be unaffected and continue to represent the outstanding membership interests of Surviving Entity, which shall constitute the only outstanding membership interests of Surviving Entity immediately following the Effective Time.

(iv) Each Partnership Common Unit held in the Partnership’s treasury or held by the General Partner immediately prior to the Effective Time shall be cancelled and extinguished without any conversion thereof, and no consideration or payment shall be delivered or deliverable in exchange therefor or in payment thereof.

(b) Certain Adjustments. If, between the Execution Date and the Effective Time (and as permitted by Article V), the outstanding Contango Common Stock or Partnership Common Units shall have been changed into, or exchanged for, a different number of shares or units or a different class of shares or units by reason of any stock or unit dividend, subdivision, reorganization, reclassification, recapitalization, stock or unit split, reverse stock or unit split, combination or exchange of shares or units, or any similar event shall have occurred, then the Partnership Common Unit Exchange Ratio shall be equitably adjusted, without duplication, to proportionally reflect such change; provided, however, that nothing in this Section 2.1(b) shall be construed to permit any party hereto to take any action with respect to its securities that is prohibited by Section 5.1 or the other terms of this Agreement.

Section 2.2 Treatment of Partnership Phantom Units.

(a) As of immediately prior to the Effective Time, each phantom unit (each, a “Partnership Phantom Unit”) granted under the Mid-Con Energy Partners, LP Long-Term Incentive Program (the “Partnership Equity Plan”) then outstanding, whether then vested or unvested, shall, in accordance with the terms and conditions under the applicable award agreements evidencing such Partnership Phantom Units, immediately and fully vest. As of the Effective Time, automatically and without any action on the part of the holder thereof, each award

of vested Partnership Phantom Units shall be cancelled and converted into the right to receive a number of shares of Contango Common Stock equal to the product of (1) the number of Partnership Common Units subject to such Partnership Phantom Unit award immediately prior to the Effective Time, multiplied by (2) the Partnership Common Unit Exchange Ratio (with any resulting fractional shares settled in accordance with Section 2.3(g)), subject to any required tax withholdings as provided in Section 2.4.

(b) Prior to the Effective Time, the Partnership shall take all action necessary to provide for the treatment of the Partnership Phantom Units as set forth in this Section 2.2. The Partnership shall ensure that, as of the Effective Time, no participant in any employee or director unit option, unit purchase or equity compensation plan, arrangement or agreement of the Partnership shall have any rights thereunder to acquire, or other rights in respect of, the capital stock of the Partnership or any of its Subsidiaries, or any other equity interest therein (including “phantom” equity or equity appreciation rights).

Section 2.3 Exchange and Payment.

(a) Immediately after the Effective Time, Contango shall deposit (or cause to be deposited) with a bank or trust company designated as exchange agent by Contango and reasonably acceptable to the Partnership (the “Exchange Agent”), in trust for the benefit of holders of Partnership Common Units outstanding immediately prior to the Effective Time (other than holders of units to the extent such units are to be cancelled) book-entry shares (or certificates if requested) representing shares of Contango Common Stock issuable pursuant to Section 2.1(a). In addition, Contango shall make available by depositing with the Exchange Agent, as necessary from time to time after the Effective Time, any dividends or distributions payable pursuant to Section 2.3(e) and any cash in lieu of fractional shares of Contango Common Stock payable pursuant to Section 2.3(g), in each case without interest. All certificates representing shares of Contango Common Stock, dividends, distributions and cash deposited with the Exchange Agent are hereinafter referred to as the “Exchange Fund.”

(b) As soon as reasonably practicable after the Effective Time, Contango shall cause the Exchange Agent to mail to each holder of record of certificate(s) (“Certificates”) that represented outstanding Partnership Common Units and uncertificated Partnership Common Units represented by book entry (“Book-Entry Units”), each as of immediately prior to the Effective Time, that were converted into the right to the Merger Consideration pursuant to Section 2.1(a)(i), any dividends or distributions payable pursuant to Section 2.3(e) and any cash in lieu of fractional shares of Contango Common Stock payable pursuant to Section 2.3(g), (i) a form of letter of transmittal (which shall specify that delivery shall be effected, and risk of loss and title to the Certificates held by such Person shall pass, only upon proper delivery of the Certificates to the Exchange Agent, and which letter shall be in customary form and contain such other provisions as Contango or the Exchange Agent may reasonably specify) and (ii) instructions for use in effecting the surrender of such Certificates (or affidavits of loss in lieu thereof as provided in Section 2.3(k)) or Book-Entry Units in exchange for the Merger Consideration, any dividends or other distributions payable pursuant to Section 2.3(e) and any cash in lieu of fractional shares of Contango Common Stock payable pursuant to Section 2.3(g).

(c) As soon as reasonably practicable after the Effective Time and upon surrender of a Certificate (or affidavit of loss in lieu thereof as provided in Section 2.3(k)), to the Exchange Agent, together with such letter of transmittal, duly completed and validly executed in accordance with the instructions thereto, and such other documents (including with respect of Book-Entry Units) as the Exchange Agent may reasonably require, the holder of Partnership Common Units shall be entitled to receive in exchange for the Partnership Common Units formerly represented by such Certificate or Book-Entry Units (subject to any applicable withholding Tax) (A) that number of whole shares of Contango Common Stock (after taking into account all Partnership Common Units then held by such holder under all Certificates and Book-Entry Units so surrendered) to which such holder of Partnership Common Units shall have become entitled pursuant to Section 2.1(a)(i) (which shall be in uncertificated book-entry form unless a physical certificate is requested),(B) any dividends or other distributions payable pursuant to Section 2.3(e) and (C) any cash in lieu of fractional shares of Contango Common Stock payable pursuant to Section 2.3(g), and the Certificate or Book-Entry Units so surrendered shall forthwith be cancelled. No interest will be paid or accrued on any unpaid dividends and distributions or cash in lieu of fractional shares, if any, payable to holders of Certificates or Book-Entry Units. Until surrendered as contemplated by this Section 2.3, each Certificate or Book-Entry Unit shall be deemed after the Effective Time to represent only the right to receive the Merger Consideration payable in respect thereof, any dividends or other distributions payable pursuant to Section 2.3(e) and any cash in lieu of fractional shares of Contango Common Stock payable pursuant to Section 2.3(g).

(d) If delivery of Merger Consideration is to be made to a Person other than the Person in whose name the surrendered Certificate or Book-Entry Unit is registered, it shall be a condition of payment that such Certificate so surrendered shall be properly endorsed or shall be otherwise in proper form for transfer or such Book-Entry Unit shall be properly transferred and that the Person requesting such payment shall have paid any transfer and other Taxes required by reason of the delivery of Merger Consideration to a Person other than the registered holder of such Certificate or Book-Entry Unit or shall have established to the satisfaction of Contango that such tax is not applicable.

(e) No dividends or other distributions with respect to Contango Common Stock with a record date after the Effective Time shall be paid to the holder of any unsurrendered Partnership Common Units with respect to the shares of Contango Common Stock that the holder thereof has the right to receive in accordance herewith, and no cash payment in lieu of fractional shares of Contango Common Stock shall be paid to any such holder pursuant to Section 2.3(g), in each case until the holder thereof shall surrender such Certificate(s) (or affidavit of loss in lieu thereof as provided in Section 2.3(k)) or Book-Entry Units in accordance with this Article II. Following the surrender of any such Certificates (or affidavit of loss in lieu thereof as provided in Section 2.3(k)) or Book-Entry Units in accordance with this Article II, there shall be paid to the holder of record thereof, without interest, (A) promptly after such surrender, the amount of any dividends or other distributions with a record date after the Effective Time theretofore paid with respect to such whole shares of Contango Common Stock and the amount of any cash payable in lieu of a fractional share of Contango Common Stock to which such holder is entitled pursuant to Section 2.3(g) and (B) at the appropriate payment date, the amount of dividends or other distributions with a record date after the Effective Time but prior to such surrender and a payment date subsequent to such surrender payable with respect to such whole shares of Contango Common Stock.

(f) The Merger Consideration, any dividends or other distributions payable pursuant to Section 2.3(e) and any cash in lieu of fractional shares of Contango Common Stock payable pursuant to Section 2.3(g) issued and paid upon the surrender for exchange of Certificates or Book-Entry Units in accordance with the terms of this Article II shall be deemed to have been issued and paid in full satisfaction of all rights pertaining to the shares of Partnership Common Units formerly represented by such Certificates or Book-Entry Units. At the Effective Time, the unit transfer books of the Partnership shall be closed and there shall be no further registration of transfers of the Partnership Common Units that were outstanding immediately prior to the Effective Time. If, after the Effective Time, Certificates are presented to Contango or the Exchange Agent for transfer or transfer is sought for Book-Entry Units, such Certificates or Book-Entry Units shall be cancelled and exchanged as provided in this Article II.

(g) Notwithstanding anything to the contrary contained herein, no certificates or scrip representing fractional shares of Contango Common Stock shall be issued upon the surrender for exchange of Certificates or Book-Entry Units, no dividends or other distributions with respect to the Contango Common Stock shall be payable on or with respect to any fractional share, and such fractional share interests shall not entitle the owner thereof to vote or to any other rights of a shareholder of Contango. In lieu of the issuance of any such fractional share, Contango shall pay to each former holder of record of Partnership Common Units who otherwise would be entitled to receive a fractional share of Contango Common Stock an amount in cash (without interest) determined by multiplying (i) the fraction of a share of Contango Common Stock that such holder would otherwise be entitled to receive (taking into account all Partnership Common Units held by such holder at the Effective Time and rounded to the nearest thousandth when expressed in decimal form) pursuant to Section 2.1(a)(i) by (ii) the volume weighted average closing price of one share of Contango Common Stock on the NYSE American Stock Exchange (the “NYSE American”) and the other United States exchanges, if any, on which it trades for the five trading days ending at 4:00 p.m., Eastern Time, on the last trading day immediately prior to the date on which the Effective Time shall occur, as such price is reported under the heading “U.S. Equities” by Bloomberg Financial Markets or such other source as Contango and the Partnership shall agree in writing.

(h) Any portion of the Exchange Fund that remains undistributed to the holders of Certificates or Book-Entry Units 12 months after the Effective Time shall be delivered to Contango, upon demand, and any remaining holders of Certificates or Book-Entry Units shall thereafter look only to Contango, as general creditors thereof, for payment of the Merger Consideration, any unpaid dividends or other distributions payable pursuant to Section 2.3(e) and any cash in lieu of fractional shares of Contango Common Stock payable pursuant to Section 2.3(g) (subject to abandoned property, escheat or other similar laws), without interest.

(i) None of Contango, Surviving Entity, the Exchange Agent or any other Person shall be liable to any Person in respect of Merger Consideration, dividends or other distributions with respect thereto or cash in lieu of fractional shares of Contango Common Stock properly delivered to a public official pursuant to any applicable abandoned property, escheat or similar Law. If any Certificates or Book-Entry Units shall not have been exchanged prior to two years after the Effective Time (or immediately prior to such earlier date on which the related Merger Consideration (and all dividends or other distributions with respect to shares of Contango Common Stock and any cash in lieu of fractional shares of Contango Common Stock pursuant to

this Article II), would otherwise escheat to or become the property of any Governmental Entity), any such Merger Consideration (and such dividends, distributions and cash), in respect thereof shall, to the extent permitted by applicable Law, become the property of Surviving Entity, free and clear of all claims or interest of any Person previously entitled thereto.

(j) The Exchange Agent shall invest any cash included in the Exchange Fund as directed by Contango on a daily basis. Any interest and other income resulting from such investments shall be paid to Contango.

(k) If any Certificate shall have been lost, stolen or destroyed, upon the making of an affidavit, in form and substance reasonably acceptable to Contango, of that fact by the Person claiming such Certificate to be lost, stolen or destroyed and, if required by Contango or the Exchange Agent, the posting by such Person of a bond in such amount as Contango or the Exchange Agent may determine is reasonably necessary as indemnity against any claim that may be made against it or Surviving Entity with respect to such Certificate, the Exchange Agent will deliver in exchange for such lost, stolen or destroyed Certificate the Merger Consideration payable in respect thereof, any dividends or other distributions payable pursuant to Section 2.3(e) and any cash in lieu of fractional shares of Contango Common Stock payable pursuant to Section 2.3(g).

Section 2.4 Withholding Rights. Contango and the Exchange Agent shall each be entitled to deduct and withhold, or cause to be deducted and withheld, from the consideration otherwise payable to any holder of Partnership Common Units, Partnership Phantom Units or otherwise pursuant to this Agreement such amounts as Contango or the Exchange Agent determines it is required to deduct and withhold under the Code (on behalf of itself or its Affiliates), or any provision of state, local or foreign tax Law, taking into consideration for such purposes any amounts timely paid to satisfy all or part of the applicable withholding obligations by the applicable Person to Contango and the Exchange Agent in accordance with the terms of any applicable award agreement. In order to implement the foregoing, the Mid-Con Parties shall provide Contango and the Exchange Agent, no later than five Business Days prior to the Closing Date, with a list of such Persons who have elected to satisfy all or part of the applicable withholding obligations through an alternative withholding mechanism. To the extent that amounts are so deducted and withheld, such amounts shall be treated for all purposes of this Agreement as having been paid to the Person in respect of whom such deduction and withholding was made. Contango shall use commercially reasonable efforts to promptly notify the Mid-Con Parties of any intended withholding and the amount of such withholding and cooperate with the Mid-Con Parties to reduce or eliminate any such withholding.

Section 2.5 No Dissenters’ Rights. No dissenters’ or appraisal rights shall be available with respect to the Merger or any of the other transactions contemplated hereby.

There is no Action pending or, to the knowledge of the Partnership, threatened against or affecting any present or former officer, director or

employee of any Mid-Con Group Entity in such individual’s capacity as such, other than any Action that (a) does not involve an amount in controversy in excess of $150,000 and (b) does not seek material injunctive or other non-monetary relief. No Mid-Con Group Entity or, to the knowledge of the Partnership, any of their respective properties or assets, is subject to any outstanding judgment, order, injunction, rule or decree of any Governmental Entity, except where such judgment, order, injunction, rule or decree of any Governmental Entity would not be reasonably expected to result in, individually or in the aggregate, material liability to the Mid-Con Group Entities, taken as a whole. There is no Action pending or, to the knowledge of the Partnership, threatened seeking to prevent, hinder, modify, delay or challenge the Merger or any of the other transactions contemplated by this Agreement.

Section 3.20 Oil and Gas Matters.

(a) The Partnership has made available to Contango true and complete copies of all written reports prepared since January 1, 2019 and delivered to or received by any Mid-Con Group Entity in writing on or before the Execution Date estimating the Mid-Con Group Entities’ oil and gas reserves by an unaffiliated person concerning the Oil and Gas Properties of the Mid-Con Group Entities. Except as is not and would not reasonably be expected to be material, individually or in the aggregate, to the Mid-Con Group Entities (taken as a whole), and except for property (i) sold or otherwise disposed of in the ordinary course of business since the date of the reserve report prepared by the Partnership and evaluated by Cawley, Gillespie & Associates, Inc. (“CG&A”) relating to the interests referred to therein as of December 31, 2019 (the “Mid-Con Reserve Report”) or (ii) reflected in the Mid-Con Reserve Report or in the Mid-Con SEC Documents as having been sold or otherwise disposed of (other than sales or dispositions after the Execution Date in accordance with Section 5.1(a)), the Mid-Con Group Entities have good and defensible title to all Oil and Gas Properties forming the basis for the reserves reflected in the Mid-Con Reserve Report and in each case as attributable to interests owned by the Mid-Con Group Entities, free and clear of any Liens, except for Permitted Liens. For purposes of the foregoing sentence, “good and defensible title” means that the applicable entity’s title (as of the Execution Date and as of the Closing) to each of the Oil and Gas Properties held or owned by them (or purported to be held or owned by them) that, as of the Closing Date, and subject to Permitted Liens (1) entitles such entity to receive (after satisfaction of all Production Burdens applicable thereto) not less than the net revenue interest share shown in the Mid-Con Reserve Report of all Hydrocarbons produced from such Oil and Gas Properties throughout the life of such Oil and Gas Properties except, in each case, for (i) any decreases in connection with those operations in which any Mid-Con Group Entity may elect after the Execution Date to be a non-consenting co-owner, (ii) any decreases resulting from the establishment or amendment, after the Execution Date, of pools or units, and (iii) decreases required to allow other working interest owners to make up past underproduction or pipelines to make up past under deliveries, (2) obligates such entity to bear a percentage of the costs and expenses for the maintenance and development of, and operations relating to, such Oil and Gas Properties, of not greater than the working interest shown on the Mid-Con Reserve Report for such Oil and Gas Properties except, in each case, for (i) increases that are accompanied by a proportionate (or greater) increase in net revenue interest in such Oil and Gas Properties, and (ii) for increases resulting from contribution requirements with respect to defaulting or non-consenting co-owners under applicable operating agreements or Laws that are accompanied by a proportionate (or greater) increase in net revenue interest in such Oil and Gas Properties and (3) is free and clear of all Liens, defects and imperfections of title (other than Permitted Liens).

(b) Except for any such matters that, individually or in the aggregate, have not had and would not reasonably be expected to have a Mid-Con Material Adverse Effect, the factual, non-interpretive data supplied by the Partnership to CG&A relating to the interests referred to in the Mid-Con Reserve Report, by or on behalf of the Partnership and its Subsidiaries that were material to CG&A’s evaluation of the Partnership’s and its Subsidiaries’ estimates of proved oil and gas reserves attributable to the Oil and Gas Properties of the Partnership and its Subsidiaries in connection with CG&A’s evaluation of the Mid-Con Reserve Report was, as of the time provided to CG&A, accurate in all respects. Except for any such matters that, individually or in the aggregate, have not had and would not reasonably be expected to have a Mid-Con Material Adverse Effect, the oil and gas reserve estimates of the Partnership and its Subsidiaries set forth in the Mid-Con Reserve Report are derived from reports that have been prepared internally by the Partnership’s management and evaluated by CG&A, and such reserve estimates fairly reflect the oil and gas reserves of the Partnership and its Subsidiaries at the dates indicated therein and are in accordance with SEC guidelines applicable thereto applied on a consistent basis throughout the periods involved. Except for changes generally affecting the oil and gas exploration, development and production industry (including changes in commodity prices) and normal depletion by production, there has been no change in respect of the matters addressed in the Mid-Con Reserve Report that is or would reasonably be expected to have, individually or in the aggregate, a Mid-Con Material Adverse Effect.

(c) Except as is not and would not reasonably be expected to have, individually or in the aggregate, a Mid-Con Material Adverse Effect, (i) all rentals, shut-ins and similar payments owed to any Person or individual by any Mid-Con Group Entity under (or otherwise with respect to) any Oil and Gas Leases have been properly and timely paid, (ii) all royalties, minimum royalties, overriding royalties and other Production Burdens owed by the Mid-Con Group Entities with respect to any Oil and Gas Properties owned or held by the Mid-Con Group Entities have been timely and properly paid (except for any amounts being held in suspense), (iii) none of the Mid-Con Group Entities (and, to the Partnership’s knowledge, no third party operator) has violated any provision of, or taken or failed to take any act that, with or without notice, lapse of time, or both, would constitute a default under the provisions of any Oil and Gas Lease (or entitle the lessor thereunder to cancel or terminate such Oil and Gas Lease) included in the Oil and Gas Properties owned or held by any Mid-Con Group Entity, (iv) each Oil and Gas Lease to which the Partnership and any of its Subsidiaries is a party is in full force and effect and (v) none of the Partnership or any of its Subsidiaries has received written notice from any other party to any such Oil and Gas Lease that any of the Partnership or any of its Subsidiaries is in breach or default under any Oil and Gas Lease.

(d) Except as would not be material, individually or in the aggregate, to the Mid-Con Group Entities, taken as a whole, all proceeds from the sale of Hydrocarbons produced from the Oil and Gas Properties of the Mid-Con Group Entities are being received by them in a timely manner and are not being held in suspense (by any Mid-Con Group Entity or, to the knowledge of the Partnership, any third party operator thereof or any other Person) for any reason other than awaiting preparation and approval of division order title opinions for recently drilled Wells.

Group Entity in writing on or before the Execution Date estimating the Contango Group Entities’ oil and gas reserves by an unaffiliated person concerning the Oil and Gas Properties of the Contango Group Entities. Except as is not and would not reasonably be expected to be material, individually or in the aggregate, to the Contango Group Entities (taken as a whole), and except for property (i) sold or otherwise disposed of in the ordinary course of business since the date of the reserve report prepared by Netherland, Sewell & Associates, Inc.

(b) Except for any such matters that, individually or in the aggregate, have not had and would not reasonably be expected to have a Contango Material Adverse Effect, the factual, non-interpretive data supplied by Contango to NSAI and Cobb relating to the interests referred to in the Contango Reserve Report, by or on behalf of Contango and its Subsidiaries that were material to NSAI’s and Cobb’s estimates of proved oil and gas reserves attributable to the Oil and Gas Properties of Contango and its Subsidiaries in connection with the preparation of the Contango Reserve Report was, as of the time provided to NSAI and Cobb, accurate in all respects. Except for any such matters that, individually or in the aggregate, have not had and would not reasonably be expected to have a Contango Material Adverse Effect, the oil and gas reserve estimates of Contango and its Subsidiaries set forth in the Contango Reserve Report are derived from reports that have been prepared by NSAI and Cobb, and such reserve estimates fairly reflect the oil and gas reserves of Contango and its Subsidiaries at the dates indicated therein and are in accordance with SEC guidelines applicable thereto applied on a consistent basis throughout the periods

involved. Except for changes generally affecting the oil and gas exploration, development and production industry (including changes in commodity prices) and normal depletion by production, there has been no change in respect of the matters addressed in the Contango Reserve Report that is or would reasonably be expected to have, individually or in the aggregate, a Contango Material Adverse Effect.

(d) Except as would not be material, individually or in the aggregate, to the Contango Group Entities, taken as a whole, all proceeds from the sale of Hydrocarbons produced from the Oil and Gas Properties of the Contango Group Entities are being received by them in a timely manner and are not being held in suspense (by any Contango Group Entity or, to the knowledge of Contango, any third party operator thereof or any other Person) for any reason other than awaiting preparation and approval of division order title opinions for recently drilled Wells.

(e) Since June 30, 2019, all of the Wells and all water, CO2, injection or other wells located on the Oil and Gas Leases of the Contango Group Entities or otherwise associated with an Oil and Gas Property of the Contango Group Entities have been drilled, completed and operated within the limits permitted by the applicable contracts entered into by the Contango Group Entity related to such wells and applicable Law, and all drilling and completion (and plugging and abandonment) of such wells and all related development, production and other operations have been conducted in compliance with all applicable Law except, in each case, as is not and would not reasonably be expected to be material, individually or in the aggregate, to the Contango Group Entities (taken as a whole).

(g) As of the Execution Date, and except as would not reasonably be expected to be material, individually or in the aggregate, to the Contango Group Entities (taken as a whole), and except for Production Burdens reflected in the applicable net revenue interest in the Contango Reserve Report, no Contango Group Entity is obligated by virtue of a prepayment arrangement, make up right under a production sales contract containing a “take or pay” or similar provision, production payment or any other arrangement to deliver Hydrocarbons or proceeds from the sale thereof, attributable to the Oil and Gas Properties of such Person at some future time without then or thereafter receiving the full contract price therefor.

(h) Except as is not and would not reasonably be expected to be material, individually or in the aggregate, to the Contango Group Entities (taken as a whole), none of the material Oil and Gas Properties of any Contango Group Entity is subject to any preferential purchase, consent, transfer fee, termination fee or similar right or obligation that would become operative as a result of the Merger.

There are no pending or, to the knowledge of Contango, threatened claims by any Person alleging infringement, misappropriation or dilution by any Contango Group Entity of the intellectual property rights of any Person. The conduct of the businesses of the Contango Group Entities has not infringed, misappropriated or diluted, and does not infringe, misappropriate or dilute, any intellectual property rights of any Person, except for such matters that have not and would not reasonably be expected to have, individually or in the aggregate, a Contango Material Adverse Effect.

Section 5.2 No Solicitation by the Mid-Con Parties; Recommendation of the Merger.

(a) From the Execution Date until the earlier of the Effective Time and the termination of this Agreement in accordance with its terms, the Mid-Con Parties shall not, shall cause the other Mid-Con Group Entities and the respective officers, directors, financial advisers, attorneys and accountants of the Mid-Con Group Entities to not, and shall use their reasonable best efforts to ensure that the other Representatives of the Mid-Con Group Entities do not, in each case, directly or indirectly, (i) solicit, initiate, endorse, knowingly encourage or knowingly facilitate any inquiry, proposal or offer with respect to, or the making or completion of, any Mid-Con Acquisition Proposal, or any inquiry, proposal or offer that is reasonably likely to lead to any Mid-Con Acquisition Proposal, (ii) enter into, continue or otherwise participate in any discussions or negotiations regarding, or furnish to any Person any information or data with respect to, or otherwise cooperate in any way with, any Mid-Con Acquisition Proposal, (iii) notify any Person or Group (as defined in the Partnership LPA) under the second proviso in the definition of “Outstanding” in the Partnership LPA that the limitations in such definition shall not apply or (iv) resolve, agree or propose to do any of the foregoing. The Mid-Con Parties shall, shall cause the other Mid-Con Group Entities and the respective officers, directors, financial advisers, attorneys and accountants of the Mid-Con Group Entities to, and shall use their reasonable best efforts to ensure that the other Representatives of the Mid-Con Group Entities, (A) immediately cease and cause to be terminated all existing discussions and negotiations with any Person conducted heretofore with respect to any Mid-Con Acquisition Proposal or potential Mid-Con Acquisition Proposal and immediately terminate all physical and electronic data room access previously granted to any such Person, (B) request the prompt return or destruction of all confidential information previously furnished with respect to any Mid-Con Acquisition Proposal or potential Mid-Con Acquisition Proposal, and (C) not terminate, waive, amend, release or modify any provision of any confidentiality or standstill agreement to which it or any of its Affiliates or Representatives is a party with respect to any Mid-Con Acquisition Proposal or potential Mid-Con Acquisition Proposal, and shall enforce the provisions of any such agreement, which shall include seeking any injunctive relief available to enforce such agreement (provided,

however, that the Partnership shall be permitted to grant waivers of, and not enforce, any standstill agreement, but solely to the extent that the GP Conflicts Committee has determined in good faith, after consultation with its outside counsel, that failure to take such action (I) would prohibit the counterparty from making an unsolicited Mid-Con Acquisition Proposal to the GP Conflicts Committee in compliance with this Section 5.2 and (II) would constitute a breach of its duties to the Unaffiliated Public Unitholders under applicable Law and the Partnership LPA, including any duty to act in, or not opposed to, the best interests of the Partnership or the Unaffiliated Public Unitholders). Notwithstanding the foregoing, if at any time following the Execution Date and prior to obtaining the Partnership Unitholder Approval, (1) the Partnership receives a written Mid-Con Acquisition Proposal that the GP Conflicts Committee believes in good faith to be bona fide, (2) such Mid-Con Acquisition Proposal was unsolicited and did not otherwise result from a breach of this Section 5.2, (3) the GP Conflicts Committee determines in good faith (after consultation with outside counsel and its financial advisor) that such Mid-Con Acquisition Proposal constitutes or is reasonably likely to lead to a Mid-Con Designated Proposal, and (4) the GP Conflicts Committee determines in good faith (after consultation with outside counsel) that the failure to take the actions referred to in clause (x) or (y) below would constitute a breach of its duties to the Unaffiliated Public Unitholders under applicable Law and the Partnership LPA, including any duty to act in, or not opposed to, the best interests of the Partnership or the Unaffiliated Public Unitholders, then the Partnership may (x) furnish information with respect to the Mid-Con Group Entities to the Person making such Mid-Con Acquisition Proposal pursuant to a customary confidentiality agreement containing terms substantially similar to, and no less favorable to the Mid-Con Parties than, those set forth in the Confidentiality Agreement (excluding any standstill agreement contained therein) (an “Acceptable Mid-Con Confidentiality Agreement”); provided, however, that (I) the Partnership shall provide Contango with a non-redacted copy of each confidentiality agreement any Mid-Con Group Entity has executed in accordance with this Section 5.2 and (II) any non-public information provided to any such Person shall have been previously provided to Contango or shall be provided to Contango prior to or concurrently with the time it is provided to such Person, and (y) participate in discussions or negotiations with the Person making such Mid-Con Acquisition Proposal regarding such Mid-Con Acquisition Proposal.

(b) Neither the General Partner Board nor any committee thereof (including the GP Conflicts Committee) shall:

(i) (A) withdraw (or modify or qualify in any manner adverse to the Contango Parties) the recommendation by the General Partner Board or any such committee of this Agreement, the Merger or any of the other transactions contemplated hereby, (B) recommend the approval by the unitholders of the Partnership of any Mid-Con Acquisition Proposal, or (C) resolve, agree or propose to take any such actions (each such action set forth in this Section 5.2(b)(i) being referred to herein as a “Mid-Con Adverse Recommendation Change”); or

(ii) cause or permit the Mid-Con Parties or any Mid-Con Subsidiary to enter into any letter of intent, memorandum of understanding, agreement in principle, acquisition agreement, merger agreement, option agreement, joint venture agreement, partnership agreement or other Contract, except for an Acceptable Mid-Con Confidentiality Agreement (each, a “Mid-Con Alternative Acquisition Agreement”), in

each case constituting or related to, or which is intended to or is reasonably likely to lead to, any Mid-Con Acquisition Proposal, or resolve, agree or propose to take any such actions.

Notwithstanding the foregoing, at any time prior to obtaining the Partnership Unitholder Approval, the GP Conflicts Committee may, if it determines in good faith (after consultation with outside counsel) that the failure to do so would result in a breach of its duties to the Unaffiliated Public Unitholders under applicable Law and the Partnership LPA, including any duty to act in, or not opposed to, the best interests of the Partnership or the Unaffiliated Public Unitholders, taking into account all adjustments to the terms of this Agreement that may be offered by the Contango Parties pursuant to this Section 5.2, make a Mid-Con Adverse Recommendation Change in response to either (x) a Mid-Con Designated Proposal or (y) a Mid-Con Intervening Event; provided, however, that the GP Conflicts Committee may not make a Mid-Con Adverse Recommendation Change in response to a Mid-Con Designated Proposal unless:

(A) the Partnership notifies Contango in writing at least four Business Days before taking that action of its intention to do so (the four Business Day period commencing on the date of such notice, the “Mid-Con Designated Proposal Negotiation Period”), and specifies the reasons therefor, including the terms and conditions of, and the identity of the Person making, such Mid-Con Designated Proposal, and contemporaneously furnishes a copy (if any) of the proposed Mid-Con Alternative Acquisition Agreement and any other relevant transaction documents (it being understood and agreed that any amendment to the financial terms or any other material term of such Mid-Con Designated Proposal shall require a new written notice by the Partnership and the Mid-Con Designated Proposal Negotiation Period shall be extended for an additional three Business Days from the date of Contango’s receipt of notice of such amendment); and

(B) if Contango makes a proposal during the Mid-Con Designated Proposal Negotiation Period to adjust the terms and conditions of this Agreement, the GP Conflicts Committee, after taking into consideration the adjusted terms and conditions of this Agreement as proposed by Contango, continues to determine in good faith (after consultation with outside counsel and its financial advisor) that such Mid-Con Designated Proposal continues to be a Mid-Con Designated Proposal and that the failure to make a Mid-Con Adverse Recommendation Change would result in a breach of its duties to the Unaffiliated Public Unitholders under applicable Law and the Partnership LPA, including any duty to act in, or not opposed to, the best interests of the Partnership or the Unaffiliated Public Unitholders;

provided further that the GP Conflicts Committee may not make a Mid-Con Adverse Recommendation Change in response to a Mid-Con Intervening Event unless:

(1) the Partnership provides Contango with written information describing such Mid-Con Intervening Event in reasonable detail as soon as reasonably practicable after becoming aware of it;

(2) the Partnership keeps Contango reasonably informed of developments with respect to such Mid-Con Intervening Event;

(3) the Partnership notifies Contango in writing at least four Business Days before making a Mid-Con Adverse Recommendation Change with respect to such Mid-Con Intervening Event of its intention to do so and specifies the reasons therefor (the four Business Day period commencing on the date of such notice, the “Mid-Con Intervening Event Negotiation Period”); and

(4) if Contango makes a proposal during such the Mid-Con Intervening Event Negotiation Period to adjust the terms and conditions of this Agreement, the GP Conflicts Committee, after taking into consideration the adjusted terms and conditions of this Agreement as proposed by Contango, continues to determine in good faith (after consultation with outside counsel) that the failure to make such Mid-Con Adverse Recommendation Change would result in a breach of its duties to the Unaffiliated Public Unitholders under applicable Law and the Partnership LPA, including any duty to act in, or not opposed to, the best interests of the Partnership or the Unaffiliated Public Unitholders.

During the Mid-Con Designated Proposal Negotiation Period or Mid-Con Intervening Event Negotiation Period, as applicable, the Mid-Con Parties shall, and shall cause their financial and legal advisors to, negotiate with Contango in good faith (to the extent Contango seeks to negotiate) regarding any revisions to the terms of the transactions contemplated by this Agreement proposed by Contango.

(c) In addition to the obligations of the Partnership set forth in Section 5.2(a) and Section 5.2(b), the Partnership promptly (and in any event within 24 hours of receipt) shall advise Contango in writing in the event any Mid-Con Group Entity or any of their Representatives receives (i) any inquiry or request for information, discussion or negotiation that is reasonably likely to lead to or that contemplates a Mid-Con Acquisition Proposal or (ii) any proposal or offer that is or is reasonably likely to lead to a Mid-Con Acquisition Proposal, in each case together with a description of the material terms and conditions of and facts surrounding any such inquiry, request, proposal or offer, the identity of the Person making any such inquiry, request, proposal or offer, and a copy of any written proposal, offer or draft agreement provided by such Person. The Partnership shall keep Contango informed (orally and in writing) in all material respects on a timely basis of the status and details (including, within 24 hours after the occurrence of any amendment, modification, development, discussion or negotiation) of any such Mid-Con Acquisition Proposal, request, inquiry, proposal or offer, including furnishing copies of any written inquiries, correspondence and draft documentation, and written summaries of any material oral inquiries or discussions. Without limiting any of the foregoing, the Partnership shall promptly (and in any event within 24 hours) notify Contango orally and in writing if it determines to begin providing information or to engage in discussions or negotiations concerning a Mid-Con Acquisition Proposal pursuant to Section 5.2(a) or Section 5.2(b) and shall in no event begin providing such information or engaging in such discussions or negotiations prior to providing such notice. The Partnership shall provide Contango with at least 24 hours prior notice (or such shorter

notice as may be provided to the GP Conflicts Committee) of a meeting of the GP Conflicts Committee at which the GP Conflicts Committee is reasonably expected to consider a Mid-Con Acquisition Proposal.

(d) The Mid-Con Parties shall not, and shall cause the Mid-Con Subsidiaries not to, enter into any confidentiality agreement with any Person subsequent to the Execution Date that would restrict any Mid-Con Party’s ability to comply with any of the terms of this Section 5.2, and the Partnership represents that neither any Mid-Con Party nor any of the Mid-Con Subsidiaries is a party to any such agreement.

(e) Nothing contained in Section 5.2(a) shall prohibit the Partnership from taking and disclosing a position contemplated by Rule 14e-2(a), Rule 14d-9 or Item 1012(a) of Regulation M-A promulgated under the Exchange Act; provided, however, that any such disclosure (other than a “stop, look and listen” communication or similar communication of the type contemplated by Section 14d-9(f) under the Exchange Act) shall be deemed to be a Mid-Con Adverse Recommendation Change (including for purposes of Section 7.1(c)(ii)) unless the General Partner Board, after receiving a recommendation to that effect from the GP Conflicts Committee, expressly reaffirms its recommendation to the Partnership’s unitholders in favor of the approval of this Agreement and the Merger in such disclosure and expressly rejects any applicable Mid-Con Acquisition Proposal.

(f) The parties hereto agree that the provisions of paragraph 2 of the Confidentiality Agreement relating to prohibiting disclosure to any Person that discussions with respect to the Proposed Transaction (as defined in the Confidentiality Agreement) are taking place, or other facts with respect to such discussions, including the status thereof, shall be suspended, effective immediately, and will remain suspended unless and until this Agreement is terminated in accordance with its terms, at which time such provisions will be reinstated with full force and effect in accordance with the Confidentiality Agreement.

(g) For purposes of this Agreement:

(i) “Mid-Con Acquisition Proposal” means any proposal or offer with respect to any direct or indirect acquisition or purchase, in one transaction or a series of transactions, and whether through any merger, reorganization, consolidation, tender offer, self-tender, exchange offer, stock acquisition, asset acquisition, binding share exchange, business combination, recapitalization, liquidation, dissolution, joint venture or otherwise, of (A) assets or businesses of the Mid-Con Group Entities that generate 20% or more of the net revenues or net income (for the 12-month period ending on the last day of the Partnership’s most recently completed fiscal quarter) or that represent 20% or more of the total assets (based on fair market value) of the Mid-Con Group Entities, taken as a whole, immediately prior to such transaction, or (B) 20% or more of any class of capital stock, other equity securities or voting power of any Mid-Con Group Entity or any resulting parent company of any Mid-Con Group Entity, in each case other than the Merger and other transactions contemplated by this Agreement.

(ii) “Mid-Con Designated Proposal” means any unsolicited bona fide binding written Mid-Con Acquisition Proposal that the GP Conflicts Committee

determines in good faith (after consultation with outside counsel and its financial advisor), taking into account all legal, financial, regulatory and other aspects of the proposal and the Person making the proposal, is (A) more favorable to the unitholders of the Partnership from a financial point of view than the Merger and the other transactions contemplated by this Agreement (including any adjustment to the terms and conditions proposed by Contango in response to such proposal) and (B) reasonably likely of being completed on the terms proposed on a timely basis; provided, however, that, for purposes of this definition of “Mid-Con Designated Proposal,” references in the term “Mid-Con Acquisition Proposal” to “20%” shall be deemed to be references to “50%”; and

(iii) “Mid-Con Intervening Event” means a material event or circumstance that was not known or reasonably foreseeable to the GP Conflicts Committee prior to the execution of this Agreement (or if known, the consequences of which were not known or reasonably foreseeable), which event or circumstance, or any material consequence thereof, becomes known to the GP Conflicts Committee prior to the receipt of the Partnership Unitholder Approval that does not relate to (A) a Mid-Con Acquisition Proposal, (B) any Contango Group Entity (including any Contango Material Adverse Effect), (C) any actions taken pursuant to this Agreement or (D) any changes in the price of Contango Common Stock or Partnership Common Units; provided, however, that in no event shall the following events or circumstances constitute a Mid-Con Intervening Event: (i) the receipt, existence or terms of a Mid-Con Acquisition Proposal or any matter relating thereto or consequence thereof, (ii) events, facts or circumstances, developments or occurrences affecting the oil and gas exploration, development and production industries generally (including any change in the price of Hydrocarbons or industry margins), (iii) events, facts or circumstances, developments or occurrences affecting the United States or global economic conditions or financial, credit, debt, securities or other capital markets in general, or (iv) any outbreak of, acts of or escalation of hostilities, terrorism, war or other similar national emergency, provided that, in the case of clauses (ii) and (iii), the impact on the Mid-Con Group Entities, taken as a whole, is not materially disproportionate to the impact on similarly situated parties.

Section 5.3 No Solicitation by the Contango Parties; Recommendation of the Merger.

(a) From the Execution Date until the earlier of the Effective Time and the termination of this Agreement in accordance with its terms, the Contango Parties shall not, shall cause the other Contango Group Entities and the respective officers, directors, financial advisers, attorneys and accountants of the Contango Group Entities to not, and shall use their reasonable best efforts to ensure that the other Representatives of the Contango Group Entities do not, in each case, directly or indirectly, (i) solicit, initiate, endorse, knowingly encourage or knowingly facilitate any inquiry, proposal or offer with respect to, or the making or completion of, any Contango Acquisition Proposal, or any inquiry, proposal or offer that is reasonably likely to lead to any Contango Acquisition Proposal, (ii) enter into, continue or otherwise participate in any discussions or negotiations regarding, or furnish to any Person any information or data with respect to, or otherwise cooperate in any way with, any Contango Acquisition Proposal or (iii) resolve, agree or propose to do any of the foregoing. The Contango Parties shall, shall cause the other Contango Group Entities and the respective officers, directors, financial advisers, attorneys and accountants of the Contango Group Entities to, and shall use their reasonable best efforts to ensure

that the other Representatives of the Contango Group Entities, (A) immediately cease and cause to be terminated all existing discussions and negotiations with any Person conducted heretofore with respect to any Contango Acquisition Proposal or potential Contango Acquisition Proposal and immediately terminate all physical and electronic data room access previously granted to any such Person, (B) request the prompt return or destruction of all confidential information previously furnished with respect to any Contango Acquisition Proposal or potential Contango Acquisition Proposal, and (C) not terminate, waive, amend, release or modify any provision of any confidentiality or standstill agreement to which it or any of its Affiliates or Representatives is a party with respect to any Contango Acquisition Proposal or potential Contango Acquisition Proposal, and shall enforce the provisions of any such agreement, which shall include seeking any injunctive relief available to enforce such agreement (provided, however, that Contango shall be permitted to grant waivers of, and not enforce, any standstill agreement, but solely to the extent that the Contango Board has determined in good faith, after consultation with its outside counsel, that failure to take such action (I) would prohibit the counterparty from making an unsolicited Contango Acquisition Proposal to the Contango Board in compliance with this Section 5.3 and (II) would constitute a breach of its fiduciary duties to the shareholders of Contango under applicable Law). Notwithstanding the foregoing, if at any time following the Execution Date and prior to obtaining the Contango Shareholder Approval, (1) Contango receives a written Contango Acquisition Proposal that the Contango Board believes in good faith to be bona fide, (2) such Contango Acquisition Proposal was unsolicited and did not otherwise result from a breach of this Section 5.3, (3) the Contango Board determines in good faith (after consultation with outside counsel and its financial advisor) that such Contango Acquisition Proposal constitutes or is reasonably likely to lead to a Contango Designated Proposal, and (4) the Contango Board determines in good faith (after consultation with outside counsel) that the failure to take the actions referred to in clause (x) or (y) below would constitute a breach of its fiduciary duties to the shareholders of Contango under applicable Law, then Contango may (x) furnish information with respect to the Contango Group Entities to the Person making such Contango Acquisition Proposal pursuant to a customary confidentiality agreement containing terms substantially similar to, and no less favorable to the Contango Parties than, those set forth in the Confidentiality Agreement (excluding any standstill agreement contained therein) (an “Acceptable Contango Confidentiality Agreement”); provided, however, that (I) Contango shall provide the Partnership with a non-redacted copy of each confidentiality agreement any Contango Group Entity has executed in accordance with this Section 5.3 and (II) any non-public information provided to any such Person shall have been previously provided to the Partnership or shall be provided to the Partnership prior to or concurrently with the time it is provided to such Person, and (y) participate in discussions or negotiations with the Person making such Contango Acquisition Proposal regarding such Contango Acquisition Proposal.

(b) Neither the Contango Board nor any committee thereof shall:

(i) (A) withdraw (or modify or qualify in any manner adverse to the Mid-Con Parties) the recommendation or declaration of advisability by the Contango Board or any such committee of this Agreement or any of the other transactions contemplated hereby, (B) recommend or otherwise declare advisable the approval by the shareholders of Contango of any Contango Acquisition Proposal, or (C) resolve, agree or propose to take any such actions (each such action set forth in this Section 5.3(b)(i) being referred to herein as a “Contango Adverse Recommendation Change”); or

(ii) cause or permit the Contango Parties or any Contango Subsidiary to enter into any letter of intent, memorandum of understanding, agreement in principle, acquisition agreement, merger agreement, option agreement, joint venture agreement, partnership agreement or other Contract, except for an Acceptable Contango Confidentiality Agreement (each, a “Contango Alternative Acquisition Agreement”), in each case constituting or related to, or that is intended to or is reasonably likely to lead to, any Contango Acquisition Proposal, or resolve, agree or propose to take any such actions.

Notwithstanding the foregoing, at any time prior to obtaining the Contango Shareholder Approval, the Contango Board may, if it determines in good faith (after consultation with outside counsel) that the failure to do so would result in a breach of its fiduciary duties to the shareholders of Contango under applicable Law, taking into account all adjustments to the terms of this Agreement that may be offered by the Partnership pursuant to this Section 5.3, make a Contango Adverse Recommendation Change in response to either (x) a Contango Designated Proposal or (y) a Contango Intervening Event; provided, however, that the Contango Board may not make a Contango Adverse Recommendation Change in response to a Contango Designated Proposal unless:

(A) Contango notifies the Partnership in writing at least four Business Days before taking that action of its intention to do so (the four Business Day period commencing on the date of such notice, the “Contango Designated Proposal Negotiation Period”), and specifies the reasons therefor, including the terms and conditions of, and the identity of the Person making, such Contango Designated Proposal, and contemporaneously furnishes a copy (if any) of the proposed Contango Alternative Acquisition Agreement and any other relevant transaction documents (it being understood and agreed that any amendment to the financial terms or any other material term of such Contango Designated Proposal shall require a new written notice by Contango and the Contango Designated Proposal Negotiation Period shall be extended for an additional three Business Days from the date of the Partnership’s receipt of notice of such amendment); and

(B) if the Partnership makes a proposal during Contango Designated Proposal Negotiation Period to adjust the terms and conditions of this Agreement, the Contango Board, after taking into consideration the adjusted terms and conditions of this Agreement as proposed by the Partnership, continues to determine in good faith (after consultation with outside counsel and its financial advisor) that such Contango Designated Proposal continues to be a Contango Designated Proposal and that the failure to make a Contango Adverse Recommendation Change would result in a breach of its fiduciary duties to the shareholders of Contango under applicable Law;

provided further that the Contango Board may not make a Contango Adverse Recommendation Change in response to a Contango Intervening Event unless:

(1) Contango provides the Partnership with written information describing such Contango Intervening Event in reasonable detail as soon as reasonably practicable after becoming aware of it;

(2) Contango keeps the Partnership reasonably informed of developments with respect to such Contango Intervening Event;

(3) Contango notifies the Partnership in writing at least four Business Days before making a Contango Adverse Recommendation Change with respect to such Contango Intervening Event of its intention to do so and specifies the reasons therefor (the four Business Day period commencing on the date of such notice, the “Contango Intervening Event Negotiation Period”); and

(4) if the Partnership makes a proposal during the Contango Intervening Event Negotiation Period to adjust the terms and conditions of this Agreement, the Contango Board, after taking into consideration the adjusted terms and conditions of this Agreement as proposed by the Partnership, continues to determine in good faith (after consultation with outside counsel) that the failure to make such Contango Adverse Recommendation Change would result in a breach of its fiduciary duties to the shareholders of Contango under applicable Law.

During the Contango Designated Proposal Negotiation Period or the Contango Intervening Event Negotiation Period, as applicable, Contango shall, and shall cause its financial and legal advisors to, negotiate with the Partnership in good faith (to the extent the Partnership seeks to negotiate) regarding any revisions to the terms of the transactions contemplated by this Agreement proposed by the Partnership.

(c) In addition to the obligations of Contango set forth in Section 5.3(a) and Section 5.3(b), Contango promptly (and in any event within 24 hours of receipt) shall advise the Partnership in writing in the event any Contango Group Entity or any of their Representatives receives (i) any inquiry or request for information, discussion or negotiation that is reasonably likely to lead to or that contemplates a Contango Acquisition Proposal or (ii) any proposal or offer that is or is reasonably likely to lead to a Contango Acquisition Proposal, in each case together with a description of the material terms and conditions of and facts surrounding any such inquiry, request, proposal or offer, the identity of the Person making any such inquiry, request, proposal or offer, and a copy of any written proposal, offer or draft agreement provided by such Person. Contango shall keep the Partnership informed (orally and in writing) in all material respects on a timely basis of the status and details (including, within 24 hours after the occurrence of any amendment, modification, development, discussion or negotiation) of any such Contango Acquisition Proposal, request, inquiry, proposal or offer, including furnishing copies of any written inquiries, correspondence and draft documentation, and written summaries of any material oral inquiries or discussions. Without limiting any of the foregoing, Contango shall promptly (and in any event within 24 hours) notify the Partnership orally and in writing if it determines to begin providing information or to engage in discussions or negotiations concerning a Contango Acquisition Proposal pursuant to Section 5.3(a) or Section 5.3(b) and shall in no event begin providing such information or engaging in such discussions or negotiations prior to providing such notice. Contango shall provide the Partnership with at least 24 hours prior notice (or such shorter notice as may be provided to the Contango Board) of a meeting of the Contango Board at which the Contango Board is reasonably expected to consider a Contango Acquisition Proposal.

(d) The Contango Parties shall not, and shall cause the Contango Subsidiaries not to, enter into any confidentiality agreement with any Person subsequent to the Execution Date that would restrict either Contango Party’s ability to comply with any of the terms of this Section 5.3, and Contango represents that none of the Contango Parties nor any of the Contango Subsidiaries is a party to any such agreement.

(e) Nothing contained in Section 5.3(a) shall prohibit Contango from taking and disclosing a position contemplated by Rule 14e-2(a), Rule 14d-9 or Item 1012(a) of Regulation M-A promulgated under the Exchange Act; provided, however, that any such disclosure (other than a “stop, look and listen” communication or similar communication of the type contemplated by Section 14d-9(f) under the Exchange Act) shall be deemed to be a Contango Adverse Recommendation Change (including for purposes of Section 7.1(d)(ii)) unless the Contango Board expressly reaffirms its recommendation to Contango’s shareholders in favor of the approval of the Contango Stock Issuance in such disclosure and expressly rejects any applicable Contango Acquisition Proposal.

(f) For purposes of this Agreement:

(i) “Contango Acquisition Proposal” means any proposal or offer with respect to any direct or indirect acquisition or purchase, in one transaction or a series of transactions, and whether through any merger, reorganization, consolidation, tender offer, self-tender, exchange offer, stock acquisition, asset acquisition, binding share exchange, business combination, recapitalization, liquidation, dissolution, joint venture or otherwise, of (A) assets or businesses of the Contango Group Entities that generate 20% or more of the net revenues or net income (for the 12-month period ending on the last day of Contango’s most recently completed fiscal quarter) or that represent 20% or more of the total assets (based on fair market value) of the Contango Group Entities, taken as a whole, immediately prior to such transaction, or (B) 20% or more of any class of capital stock, other equity securities or voting power of any Contango Group Entity or any resulting parent company of any Contango Group Entity, in each case other than the Merger and other transactions contemplated by this Agreement.

(ii) “Contango Designated Proposal” means any unsolicited bona fide binding written Contango Acquisition Proposal that the Contango Board determines in good faith (after consultation with outside counsel and its financial advisor), taking into account all legal, financial, regulatory and other aspects of the proposal and the Person making the proposal, is (A) more favorable to the shareholders of Contango from a financial point of view than the Merger and the other transactions contemplated by this Agreement (including any adjustment to the terms and conditions proposed by Contango in response to such proposal) and (B) reasonably likely of being completed on the terms proposed on a timely basis; provided, however, that, for purposes of this definition of “Contango Designated Proposal,” references in the term “Contango Acquisition Proposal” to “20%” shall be deemed to be references to “50%”; and

(iii) “Contango Intervening Event” means a material event or circumstance that was not known or reasonably foreseeable to the Contango Board prior to the execution of this Agreement (or if known, the consequences of which were not known

or reasonably foreseeable), which event or circumstance, or any material consequence thereof, becomes known to the Contango Board prior to the receipt of the Contango Shareholder Approval that does not relate to (A) a Contango Acquisition Proposal, (B) any Mid-Con Group Entity (including any Mid-Con Material Adverse Effect), (C) any actions taken pursuant to this Agreement or (D) any changes in the price of Contango Common Stock or Partnership Common Units; provided, however, that in no event shall the following events or circumstances constitute a Contango Intervening Event: (i) the receipt, existence or terms of a Contango Acquisition Proposal or any matter relating thereto or consequence thereof, (ii) events, facts or circumstances, developments or occurrences affecting the oil and gas exploration, development and production industries generally (including any change in the price of Hydrocarbons or industry margins), (iii) events, facts or circumstances, developments or occurrences affecting the United States or global economic conditions or financial, credit, debt, securities or other capital markets in general, or (iv) any outbreak of, acts of or escalation of hostilities, terrorism, war or other similar national emergency, provided that, in the case of clauses (ii) and (iii), the impact on the Contango Group Entities, taken as a whole, is not materially disproportionate to the impact on similarly situated parties.

Section 5.4 Preparation of Registration Statement and Consent Statement/Proxy Statement/Prospectus; Contango Special Shareholders Meeting.

(a) As promptly as practicable following the Execution Date, (i) the Partnership and Contango shall prepare and file with the SEC the Consent Statement/Proxy Statement/Prospectus to be sent to (A) the unitholders of the Partnership in connection with the Mid-Con Written Consent and (B) the shareholders of Contango relating to the special meeting of Contango’s shareholders (the “Contango Special Shareholders Meeting”) to be held to consider the approval of the Contango Stock Issuance or, if elected by Contango in accordance with Section 5.4(c), in connection with the Contango Written Consent and (ii) Contango shall prepare (with the Partnership’s reasonable cooperation) and file with the SEC the Registration Statement, in which the Consent Statement/Proxy Statement/Prospectus will be included as a prospectus, in connection with the registration under the Securities Act of the Contango Common Stock to be issued in the Merger. Each of the Partnership and Contango shall use its reasonable best efforts to have the Registration Statement declared effective under the Securities Act as promptly as practicable after such filing and to keep the Registration Statement effective as long as is necessary to consummate the Merger and the other transactions contemplated hereby. Contango shall also take any action (other than qualifying to do business in any jurisdiction in which it is not now so qualified or filing a general consent to service of process) required to be taken under any applicable state securities or “blue sky” laws in connection with the issuance of shares of Contango Common Stock in the Merger and the Partnership shall furnish all information concerning the Partnership and the holders of Partnership Common Units as may be reasonably requested in connection with any such action. The Partnership shall use reasonable best efforts to cause the Consent Statement/Proxy Statement/Prospectus to be mailed to the Partnership’s unitholders, and Contango shall use reasonable best efforts to cause the Consent Statement/Proxy Statement/Prospectus to be mailed to Contango’s shareholders, in each case, as promptly as practicable after the Registration Statement is declared effective under the Securities Act. No filing of, or amendment or supplement to, the Registration Statement or the Consent Statement/Prospectus will be made by Contango or the Partnership, as applicable, without providing the other a reasonable opportunity to review and

comment thereon. Contango or the Partnership, as applicable, will advise the others promptly after it receives oral or written notice thereof, of the time when the Registration Statement has become effective or any amendment or supplement thereto has been filed, the issuance of any stop order, the suspension of the qualification of the Contango Common Stock issuable in connection with the Merger for offering or sale in any jurisdiction or any oral or written request by the SEC for amendment of the Consent Statement/Proxy Statement/Prospectus or the Registration Statement or comments thereon and responses thereto or requests by the SEC for additional information, and will promptly provide the others with copies of any written communication from the SEC or any state securities commission and a reasonable opportunity to participate in the responses thereto. If at any time prior to the Effective Time any information relating to the Mid-Con Parties or the Contango Parties, or any of their respective Affiliates, officers or directors, should be discovered by the Partnership or Contango that should be set forth in an amendment or supplement to any of the Registration Statement or the Consent Statement/Proxy Statement/Prospectus, so that any of such documents would not contain any misstatement of a material fact or omit to state any material fact necessary to make the statements therein, in light of the circumstances under which they were made, not misleading, the party that discovers such information shall promptly notify the other parties hereto and an appropriate amendment or supplement describing such information shall promptly be filed with the SEC and, to the extent required under applicable Law, disseminated to the unitholders of the Partnership and the shareholders of Contango; provided, however, that the delivery of such notice and the filing of any such amendment or supplement shall not affect or be deemed to modify any representation or warranty made by any party hereunder or otherwise affect the remedies available hereunder to any party.

(b) As promptly as practicable after the Registration Statement is declared effective under the Securities Act, the Partnership shall distribute to the Partnership’s unitholders the Consent Statement/Proxy Statement/Prospectus, which shall include a form of consent that may be executed by holders of Partnership Common Units in connection with the Mid-Con Written Consent. Except in the case of a Mid-Con Adverse Recommendation Change permitted by Section 5.2(b), the Partnership, through the General Partner Board in accordance with the recommendation from the GP Conflicts Committee, shall (i) recommend to its unitholders that they approve this Agreement and the transactions contemplated hereby, including the Merger, (ii) include such recommendation in the Consent Statement/Proxy Statement/Prospectus and (iii) publicly reaffirm such recommendation within 24 hours after a request to do so by Contango. Without limiting the generality of the foregoing, the Partnership agrees that (x) except in the event of a Mid-Con Adverse Recommendation Change permitted by Section 5.2(b), the Partnership shall use its reasonable best efforts to obtain the Partnership Unitholder Approval pursuant to the Mid-Con Written Consent and (y) its obligations pursuant to this Section 5.4(b) shall not be affected by the commencement, public proposal, public disclosure or communication to the Partnership or any other Person of any Mid-Con Acquisition Proposal or the occurrence of any Mid-Con Adverse Recommendation Change.

(c) Contango may, in its sole and absolute discretion, seek to obtain the Contango Shareholder Approval at the Contango Special Shareholders Meeting or by the Contango Written Consent in accordance with this Section 5.4(c). As promptly as practicable after the Registration Statement is declared effective under the Securities Act, Contango shall:

(i) if the Contango Shareholder Approval is to be sought at the Contango Special Shareholders Meeting, establish a record date for, duly call, give notice of, convene and hold the Contango Special Shareholders Meeting solely for the purpose of obtaining the Contango Shareholder Approval and, if applicable, the advisory vote required by Rule 14a-21(c) under the Exchange Act in connection therewith. Contango may postpone or adjourn such Contango Special Shareholders Meeting solely (i) with the consent of the Partnership; (ii) (A) due to the absence of a quorum or (B) if Contango has not received proxies representing a sufficient number of shares of Contango Common Stock for the Contango Shareholder Approval, whether or not a quorum is present, to solicit additional proxies; or (iii) to allow reasonable additional time for the filing and mailing of any supplemental or amended disclosure which the Contango Board has determined in good faith after consultation with outside legal counsel is necessary under applicable Law and for such supplemental or amended disclosure to be disseminated and reviewed by Contango’s shareholders prior to such Contango Special Shareholders Meeting; provided, however, that Contango may not postpone or adjourn such Contango Special Shareholders Meeting more than a total of two times pursuant to clause (ii)(A) and/or clause (ii)(B) of this Section 5.4(c). Notwithstanding the foregoing, Contango shall, at the request of the Partnership, to the extent permitted by Law, adjourn such Contango Special Shareholders Meeting to a date specified by GP Conflicts Committee for the absence of a quorum or if Contango has not received proxies representing a sufficient number of votes for the Contango Shareholder Approval; provided, however, that Contango shall not be required to adjourn such Contango Special Shareholders Meeting more than one time pursuant to this sentence, and no such adjournment pursuant to this sentence shall be required to be for a period exceeding ten Business Days; or

(ii) if the Contango Shareholder Approval is to be sought by the Contango Written Consent, distribute to Contango’s stockholders the Consent Statement/Proxy Statement/Prospectus, which shall include a form of consent that may be executed by holders of Contango Common Stock in connection with the Contango Written Consent.

Except in the case of a Contango Adverse Recommendation Change permitted by Section 5.3(b), Contango, through the Contango Board, shall (i) recommend to its shareholders that they approve the Contango Stock Issuance, (ii) include such recommendation in the Consent Statement/Proxy Statement/Prospectus and (iii) publicly reaffirm such recommendation within 24 hours after a request to do so by the General Partner Board or the GP Conflicts Committee. Without limiting the generality of the foregoing, Contango agrees that (x) except in the event of a Contango Adverse Recommendation Change permitted by Section 5.3(b), Contango shall use its reasonable best efforts to obtain the Contango Shareholder Approval and (y) its obligations pursuant to this Section 5.4(c) shall not be affected by the commencement, public proposal, public disclosure or communication to Contango or any other Person of any Contango Acquisition Proposal or the occurrence of any Contango Adverse Recommendation Change.

Section 5.5 Access to Information; Confidentiality. Each of the Mid-Con Parties and the Contango Parties shall, and shall cause each of their Subsidiaries to, afford to each other and their respective Representatives reasonable access during normal business hours, during the period prior to the Effective Time or the termination of this Agreement in accordance with its terms, to

all their respective properties, assets, books, contracts, commitments, personnel and records and, during such period, each of the Mid-Con Parties and the Contango Parties shall, and shall cause each of their Subsidiaries to, furnish promptly to the other party: (a) a copy of each report, schedule, registration statement and other document filed or received by it during such period pursuant to the requirements of federal or state securities laws and (b) all other information concerning its business, properties and personnel as may be reasonably requested (including Tax Returns filed and those in preparation and the work papers of its auditors); provided, however, that the foregoing shall not require either party to disclose any information to the extent such disclosure would contravene applicable Law. All such information shall be held confidential in accordance with the terms of the Confidentiality and Non-Disclosure Agreement, between Contango and the Partnership, dated as of July 30, 2020 (the “Confidentiality Agreement”), which shall remain in effect notwithstanding Section 8(iii) thereof. No investigation pursuant to this Section 5.5 or information provided, made available or delivered to any party pursuant to this Agreement shall affect any of the representations, warranties, covenants, rights or remedies, or the conditions to the obligations of, the parties hereunder.

Section 5.6 Reasonable Best Efforts. Upon the terms and subject to the conditions set forth in this Agreement, each of the parties agrees to use reasonable best efforts to take, or cause to be taken, all actions that are necessary, proper or advisable to consummate and make effective, in the most expeditious manner practicable (and in any event no later than the Outside Date), the Merger and the other transactions contemplated by this Agreement, including using reasonable best efforts to accomplish the following: (i) obtain all required consents, approvals or waivers from, or participation in other discussions or negotiations with, third parties, including as required under any Mid-Con Material Contract or Contango Material Contract, (ii) obtain all necessary actions or nonactions, waivers, consents, approvals, orders and authorizations from Governmental Entities, make all necessary registrations, declarations and filings and make reasonable best efforts to obtain an approval or waiver from, or to avoid any Action by, any Governmental Entity, (iii) vigorously resist and contest any Action, including administrative or judicial Action, and seek to have vacated, lifted, reversed or overturned any decree, judgment, injunction or other order (whether temporary, preliminary or permanent) that is in effect and that could restrict, prevent or prohibit consummation of the Merger and the other transactions contemplated hereby, including by vigorously pursuing all avenues of administrative and judicial appeal and (iv) execute and deliver any additional instruments necessary to consummate the transactions contemplated hereby and fully to carry out the purposes of this Agreement; provided, however, that no Mid-Con Group Entity or Contango Group Entity shall commit to the payment of any fee, penalty or other consideration or make any other concession, waiver or amendment under any Contract in connection with obtaining any consent without the prior written consent of Contango (with respect to actions taken by the Mid-Con Group Entities) or the Partnership (with respect to actions taken by the Contango Group Entities). Each of the parties hereto shall furnish to each other party such necessary information and reasonable assistance as such other party may reasonably request in connection with the foregoing. Subject to applicable Law relating to the exchange of information, each party shall have the right to review in advance, and to the extent practicable each shall consult with the other in connection with, all of the information relating to the other parties, as the case may be, and any of their respective Subsidiaries, that appears in any filing made with, or written materials submitted to, any third party and/or any Governmental Entity in connection with the Merger and the other transactions contemplated by this Agreement. In exercising the foregoing rights, each party shall act reasonably and as promptly as practicable. Subject to applicable Law

With respect to any information shared by the parties pursuant to this Section 5.6 that is protected from disclosure under the attorney-client privilege, work product doctrine, joint defense privilege or any other privilege, the parties shall take reasonable efforts to share such information in a manner so as to preserve the applicable privilege.

Section 5.7 Takeover Laws. The Mid-Con Parties, the General Partner Board, the Contango Parties and the Contango Board shall (a) take no action to cause any Takeover Law to become applicable to this Agreement, the Merger or any of the other transactions contemplated hereby and (b) if any Takeover Law is or becomes applicable to this Agreement, the Merger or any of the other transactions contemplated hereby, use reasonable best efforts to take all action necessary to ensure that the Merger and the other transactions contemplated hereby may be consummated as promptly as practicable on the terms contemplated by this Agreement and otherwise to minimize the effect of such Takeover Law with respect to this Agreement, the Merger and the other transactions contemplated hereby.

Section 5.8 Notification of Certain MattersSection 5.9 . The Partnership and Contango shall promptly notify each other of (a) any notice or other communication received by any Mid-Con Party or Contango Party from any Governmental Entity in connection with the Merger or the other transactions contemplated hereby or from any Person alleging that the consent of such Person is or may be required in connection with the transactions contemplated hereby, (b) any other notice or communication from any Governmental Entity in connection with the transactions contemplated hereby, (c) any Action commenced or, to such party’s knowledge, threatened against, relating to or involving or otherwise affecting such party or any of its Subsidiaries which relate to the transactions contemplated hereby or (d) any change, condition or event (i) that renders or would reasonably be expected to render any representation or warranty of such party set forth in this Agreement (disregarding any materiality qualification contained therein) to be untrue or inaccurate in any material respect or (ii) that results or would reasonably be expected to result in any failure of such party to comply with or satisfy in any material respect any covenant, condition or agreement (including any condition set forth in Article VI) to be complied with or satisfied hereunder; provided, however, that no such notification shall affect any of the representations, warranties, covenants, rights or remedies, or the conditions to the obligations of, the parties hereunder.

(b) Partnership Fees.

(i) In the event that:

(A) (1) a Mid-Con Acquisition Proposal (whether or not conditional) or intention to make a Mid-Con Acquisition Proposal (whether or not conditional) is publicly made directly to the Partnership’s unitholders or is otherwise publicly disclosed, (2) this Agreement is terminated by Contango or the Partnership pursuant to Section 7.1(b)(i) or by Contango pursuant to Section 7.1(c)(i), and (3) within 12 months after the date of such termination, the Partnership enters into a written definitive agreement for a Mid-Con Acquisition Proposal made by the Person that proposed such pre-termination Mid-Con Acquisition Proposal (or an Affiliate thereof), or recommends or submits such Mid-Con Acquisition Proposal to its unitholders for adoption, or a transaction in respect of such Mid-Con Acquisition Proposal is consummated (provided, however, that for purposes of this clause (3), each reference to “20%” in the definition of “Mid-Con Acquisition Proposal” shall be deemed to be a reference to “50%”); or

(B) this Agreement is terminated by Contango pursuant to Section 7.1(c)(ii);

then, in any such event, the Partnership shall (I) pay to Contango a fee of $1,500,000 (the “Mid-Con Termination Fee”) and (II) reimburse Contango and its Affiliates for (x) all of their reasonable out-of-pocket fees and expenses (including all fees and expenses of counsel, accountants, financial advisors, experts and consultants to Contango and its Affiliates) incurred by Contango and Michael Merger Sub, or on their behalf, in connection with or related to the

authorization, preparation, investigation, negotiation, execution and performance of this Agreement and the transactions contemplated hereby (the “Contango Expenses”), up to a maximum amount of $1,500,000 and (y) in the event of a termination by Contango pursuant to Section 7.1(c), all amounts previously reimbursed by Contango to the Partnership pursuant to Section 7.3(c)(iii) (the “Contango Reimbursement Amount” and, together with the Mid-Con Termination Fee and the Contango Expenses, the “Mid-Con Termination Amount”), it being understood that in no event shall the Partnership be required to pay the Mid-Con Termination Amount on more than one occasion (although the Mid-Con Termination Fee and the Contango Expenses may be paid at different times in accordance with Section 7.3(b)(ii)); provided, however, that the payment by the Partnership of the Mid-Con Termination Amount pursuant to this Section 7.3 shall not relieve the Mid-Con Parties from any liability or damage resulting from a willful and material breach of any of its representations, warranties, covenants or agreements set forth in this Agreement or knowing and intentional fraud.

(ii) Payment of the Mid-Con Termination Fee and the Contango Reimbursement Amount shall be made by wire transfer of same-day funds to the accounts designated by Contango, (i) on the earliest of the execution of a definitive agreement with respect to, submission to the unitholders of, or consummation of, any transaction contemplated by a Mid-Con Acquisition Proposal, as applicable, in the case of a Mid-Con Termination Fee payable pursuant to Section 7.3(b)(i)(A) or (ii) as promptly as reasonably practicable after termination (and, in any event, within two Business Days thereof), in the case of a Mid-Con Termination Fee payable pursuant to Section 7.3(b)(i)(B). Payment of the Contango Expenses shall be made by wire transfer of same-day funds to the accounts designated by Contango within three Business Days after the Partnership’s having been notified of the amounts thereof by Contango.

(iii) The Partnership acknowledges that the agreements contained in this Section 7.3(b) are an integral part of the transactions contemplated by this Agreement, and that, without these agreements, the Contango Parties would not enter into this Agreement. Accordingly, if the Partnership fails promptly to pay any amounts due pursuant to this Section 7.3(b), and, in order to obtain such payment, Contango commences a suit that results in a judgment against the Partnership for the amounts set forth in this Section 7.3(b), the Partnership shall pay to Contango its costs and expenses (including reasonable attorneys’ fees and expenses) in connection with such suit, together with interest on the amounts due pursuant to this Section 7.3(b) from the date such payment was required to be made until the date of payment at the prime lending rate as published in The Wall Street Journal in effect on the date such payment was required to be made.

(i) In the event that:

(A) (1) a Contango Acquisition Proposal (whether or not conditional) or intention to make a Contango Acquisition Proposal (whether or not conditional) is publicly made directly to Contango’s shareholders or is otherwise publicly disclosed, (2) this Agreement is terminated by Contango or the Partnership pursuant to Section 7.1(b)(i) or Section 7.1(b)(iii) or by the Partnership pursuant to

Section 7.1(d)(i), and (3) within 12 months after the date of such termination, Contango enters into a written definitive agreement for a Contango Acquisition Proposal made by the Person that proposed such pre-termination Contango Acquisition Proposal (or an Affiliate thereof), or recommends or submits such Contango Acquisition Proposal to its shareholders for approval, or a transaction in respect of such Contango Acquisition Proposal is consummated (provided, however, that for purposes of this clause (3), each reference to “20%” in the definition of “Contango Acquisition Proposal” shall be deemed to be a reference to “50%”); or

(B) this Agreement is terminated (x) by the Partnership pursuant to Section 7.1(d)(ii) or (y) by Contango pursuant to Section 7.1(b)(iii) at a time at which the Partnership would have been permitted to terminate this Agreement pursuant to Section 7.1(d)(ii);

then, in any such event, Contango shall (I) pay to the Partnership the Contango Termination Fee, as determined in accordance with Section 7.3(c)(ii), and (II) reimburse the Partnership and its Affiliates for all of their reasonable out-of-pocket fees and expenses (including all fees and expenses of counsel, accountants, financial advisors, experts and consultants to the Partnership and its Affiliates) incurred by the Partnership or the General Partner, or on their behalf, in connection with or related to the authorization, preparation, investigation, negotiation, execution and performance of this Agreement and the transactions contemplated hereby (the “Mid-Con Expenses”), up to a maximum amount of the Total Mid-Con Expenses Pool, less any amounts previously reimbursed by Contango pursuant to the second sentence of Section 7.3(c)(iii) (collectively with the Contango Termination Fee, the “Contango Termination Amount”), it being understood that in no event shall Contango be required to pay the Contango Termination Amount on more than one occasion (although the Contango Termination Fee and the Mid-Con Expenses may be paid at different times in accordance with Section 7.3(c)(iv)); provided, however, that the payment by Contango of the Contango Termination Amount pursuant to this Section 7.3 shall not relieve the Contango Parties from any liability or damage resulting from a willful and material breach of any of its representations, warranties, covenants or agreements set forth in this Agreement or knowing and intentional fraud.

(ii) The “Contango Termination Fee” shall be an amount of cash equal to the lesser of (i) $1,500,000 (the “Contango Base Amount”) and (ii) the maximum amount, if any, that can be paid to the Partnership without causing the Partnership to fail the gross income requirement in Section 7704(c)(2) of the Code, treating the Contango Termination fee as non-qualifying income and after taking into consideration all other sources of non-qualifying income (such maximum amount, the “Non-Qualifying Income Cushion”), for such year, as determined by the Partnership. Notwithstanding the foregoing, in the event the Partnership receives a reasoned opinion from outside counsel or a ruling from the IRS (“Tax Guidance” ) providing that the Partnership’s receipt of the Contango Base Amount would either constitute qualifying income (as defined in Section 7704(d) of the Code) or be excluded from gross income for purposes of Section 7704 of the Code, the Contango Termination Fee shall be an amount equal to the Contango Base Amount and Contango shall, upon receiving notice that the Partnership has received the Tax Guidance, pay to the Partnership any unpaid portion of the Contango Base

Amount within five Business Days. In the event that the Partnership is not able to receive the full Contango Base Amount due to the above limitations, Contango shall place the unpaid portion in escrow by wire transfer and shall not release any portion thereof to the Partnership unless and until the Partnership receives either: (x) a letter from the Partnership’s independent accountants indicating the Non-Qualifying Income Cushion for any subsequent year (in which case Contango shall pay to the Partnership the lesser of the unpaid portion of the Contango Base Amount or the Non-Qualifying Income Cushion specified within five Business Days after Contango has been notified thereof) or (y) Tax Guidance providing that the Partnership’s receipt of such portion would either constitute qualifying income (as defined in Section 7704(d) of the Code) or be excluded from gross income for purposes of Section 7704 of the Code (in which case Contango shall pay to the Partnership any unpaid portion of the Contango Base Amount within five Business Days after Contango been notified thereof).

(iii) Contango shall reimburse the Partnership, from time to time, for all of the Partnership’s documented Mid-Con Expenses incurred by the Partnership prior to the execution of this Agreement up to a maximum amount of $250,000 (the “Negotiation Expenses”). In addition to the foregoing, Contango shall reimburse the Partnership, from time to time, for all of the Partnership’s documented Mid-Con Expenses incurred by the Partnership prior to the termination of this Agreement up to a maximum of the Total Mid-Con Expenses Pool. For the avoidance of doubt, in no event shall Contango be required to reimburse Mid-Con Expenses pursuant to Section 7.3(c)(i) or this Section 7.3(c)(iii) in an amount exceeding $1,500,000. The obligations of Contango pursuant to the first paragraph under “Fees and Expenses” in the Non-Binding Confidential Term Sheet, dated July 30, 2020, between the Partnership and Contango are hereby terminated and of no further force and effect.

(iv) Payment of the Contango Termination Fee shall be made by wire transfer of same-day funds to the accounts designated by the Partnership, (i) on the earliest of the execution of a definitive agreement with respect to, submission to the shareholders of, or consummation of, any transaction contemplated by a Contango Acquisition Proposal, as applicable, in the case of a Contango Termination Fee payable pursuant to Section 7.3(c)(i)(A) or (ii) as promptly as reasonably practicable after termination (and, in any event, within two Business Days thereof), in the case of a Contango Termination Fee payable pursuant to Section 7.3(c)(i)(B). Payment of the Mid-Con Expenses shall be made by wire transfer of same-day funds to the accounts designated by the Partnership within three Business Days after Contango’s having been notified of the amounts thereof by the Partnership; provided, however, that Contango shall not be required to make more than one payment pursuant to Section 7.3(c)(iii) in any calendar month.

(v) Contango acknowledges that the agreements contained in this Section 7.3(c) are an integral part of the transactions contemplated by this Agreement, and that, without these agreements, the Mid-Con Parties would not enter into this Agreement. Accordingly, if Contango fails promptly to pay any amounts due pursuant to this Section 7.3(c), and, in order to obtain such payment, the Partnership commences a suit that results in a judgment against Contango for the amounts set forth in this Section 7.3(c), Contango shall pay to the Partnership its costs and expenses (including reasonable

attorneys’ fees and expenses) in connection with such suit, together with interest on the amounts due pursuant to this Section 7.3(c) from the date such payment was required to be made until the date of payment at the prime lending rate as published in The Wall Street Journal in effect on the date such payment was required to be made.

Section 7.4 Amendment or Supplement. This Agreement may be amended, modified or supplemented by Contango and the Partnership by action taken or authorized by the Contango Board and the GP Conflicts Committee, respectively, at any time prior to the Effective Time, whether before or after the Partnership Unitholder Approval or the Contango Shareholder Approval has been obtained; provided, however, that after the Partnership Unitholder Approval and/or the Contango Shareholder Approval has been obtained, no amendment shall be made that pursuant to applicable Law requires further approval by the unitholders of the Partnership and/or the shareholders of Contango, as the case may be, without such further approval. This Agreement may not be amended, modified or supplemented in any manner, whether by course of conduct or otherwise, except by an instrument in writing specifically designated as an amendment hereto, signed on behalf of each of the parties in interest at the time of the amendment.

Section 7.5 Extension of Time; Waiver. At any time prior to the Effective Time, Contango and the Partnership may, by action taken or authorized by the Contango Board and the GP Conflicts Committee, respectively, to the extent permitted by applicable Law, (a) extend the time for the performance of any of the obligations or acts of the other parties, (b) waive any inaccuracies in the representations and warranties of the other parties set forth in this Agreement or any document delivered pursuant hereto or (c) subject to applicable Law, waive compliance with any of the agreements or conditions of the other parties contained herein; provided, however, that after the Partnership Unitholder Approval and/or the Contango Shareholder Approval has been obtained, no waiver may be made that pursuant to applicable Law requires further approval by the unitholders of the Partnership and/or the shareholders of Contango, as the case may be, without such further approval. Any agreement on the part of a party to any such waiver shall be valid only if set forth in a written instrument executed and delivered by a duly authorized officer on behalf of such party.
