VOTING AND SUPPORT AGREEMENT 

THIS VOTING AND SUPPORT AGREEMENT (this “Agreement”) is made and entered into as of October 25, 2020, by and among Mid-Con Energy Partners, LP, a Delaware limited partnership (the “Partnership”), Contango Oil & Gas Company, a Texas corporation (“Contango”), and each Person identified on
Exhibit A attached hereto (the “Unitholders” and each a “Unitholder”). 

WITNESSETH: 
 WHEREAS,
Contango, Michael Merger Sub, LLC, a Delaware limited liability company (“Michael Merger Sub”), the Partnership and Mid-Con Energy GP, LLC, a Delaware limited liability company
(“General Partner”), are entering into an Agreement and Plan of Merger of even date herewith (as amended, supplemented or modified from time to time, the “Merger Agreement”), which provides for, among other things,
the merger of the Partnership with and into Michael Merger Sub, with Michael Merger Sub surviving that merger as a Subsidiary of Contango (the “Merger”), on the terms and subject to the conditions set forth in the Merger Agreement;

 WHEREAS, as of the date hereof, each Unitholder is the beneficial owner (as defined in Rule 13d-3
under the Securities Exchange Act of 1934, as amended) of the number of Partnership Common Units (the “Partnership Units”) set forth opposite such Unitholder’s name on Exhibit A attached hereto; and

 WHEREAS, as a condition and inducement to the willingness of the Partnership and Contango to enter into the Merger Agreement, each
Unitholder (in such Unitholder’s capacity as such) has agreed to enter into this Agreement. 
 NOW, THEREFORE, in consideration of the
foregoing, and the mutual covenants and agreements herein contained, and intending to be legally bound hereby, the parties hereto agree as follows: 

1.    Certain Definitions. All capitalized terms that are used but not defined herein shall have the respective
meanings ascribed to them in the Merger Agreement. For all purposes of and under this Agreement, the following terms shall have the following respective meanings: 

(a)    “Expiration Date” shall mean the earlier to occur of (i) such date and time as the Merger
shall become consummated in accordance with the terms and provisions of the Merger Agreement and (ii) the termination of the Merger Agreement in accordance with its terms. 

(b)    “Involuntary Transfer” shall mean that a Unitholder ceases to be the beneficial owner of any
Partnership Units without the consent of the Unitholder as a result of an any non-volitional transfer of Subject Partnership Units and, by way of example and not by way of limitation, shall be deemed to occur
if: (i) the Involuntary Transfer is caused by a transfer of Subject Partnership Units occurring as a result of a dissolution, liquidation, reorganization, restructuring, bankruptcy, foreclosure, judicial sale or other event or transaction
involving a Unitholder or any entity through which Unitholder holds beneficial ownership of Partnership Units, and that takes place without the action or consent of the Unitholder; or (ii) the Involuntary













 
Transfer is caused by the Unitholder, or any associate or affiliate of the Unitholder, being involuntarily removed as an officer, director, manager, or general partner of a trust, limited
liability company, corporation, partnership or other corporate entity. 
 (c)    “Subject Partnership
Units” shall mean, without duplication, (i) all Partnership Units of which such Unitholder is the record or beneficial owner as of the date hereof as set forth on Exhibit A attached hereto, (ii) all
Partnership Units issuable upon conversion, exercise or exchange of options, warrants and/or other Rights to acquire Partnership Units of which such Unitholder is the record or beneficial owner as of the date hereof and (iii) all additional
Partnership Units, and all additional Partnership Units issuable upon conversion, exercise or exchange of options, warrants and/or other Rights to acquire Partnership Units, in each case of which such Unitholder acquires record or beneficial
ownership during the period from the date of this Agreement through the Expiration Date (including by way of unit dividend or distribution, split-up, recapitalization, combination, exchange of units and the
like). 
 (d)    “Transfer.” A Person shall be deemed to have effected a “Transfer” of
a Subject Partnership Unit if such Person directly or indirectly (i) sells, pledges, assigns, grants an option with respect to, transfers, tenders or disposes (by merger, by testamentary disposition, by operation of Law or otherwise) of such
Subject Partnership Unit or any interest in such Subject Partnership Unit, (ii) creates or permits to exist any Liens, other than restrictions imposed by applicable Law or pursuant to this Agreement or the Merger Agreement (or the transactions
contemplated thereby), (iii) deposits any Subject Partnership Units into a voting trust or enters into a voting agreement or arrangement or grants any proxy, power of attorney or other authorization with respect thereto that is inconsistent
with this Agreement, or (iv) agrees or commits (whether or not in writing) to take any of the actions referred to in the foregoing clauses (i) through (iii). 

2.    Transfer Restrictions. Except for an Involuntary Transfer, from the date hereof until the Expiration
Date, no Unitholder shall Transfer (or cause or permit the Transfer of) any of its Subject Partnership Units, or enter into any agreement relating thereto, except with Contango’s prior written consent and in Contango’s sole discretion. If
any Involuntary Transfer of any of such Unitholder’s Subject Partnership Units shall occur, the transferee (which term, as used herein, shall include any and all transferees and subsequent transferees of the initial transferee) shall take and
hold such Subject Partnership Units subject to all of the restrictions, liabilities and rights under this Agreement, which shall continue in full force and effect until the Expiration Date. 

3.    Agreement to Vote Partnership Units. 

(a)    Prior to the Expiration Date, each Unitholder (in such Unitholder’s capacity as such) irrevocably and
unconditionally agrees that it shall (i) within two Business Days after the Registration Statement becomes effective under the Securities Act (but, for the avoidance of doubt, not until such Registration Statement becomes effective), deliver
(or cause to be delivered) a written consent pursuant to Section 13.11 of the Partnership LPA covering all of the Subject Partnership Units that are then beneficially owned by such Unitholder approving the Merger, the Merger Agreement and any
other matters presented or proposed as to the approval of the Merger or any part or aspect thereof or any other transactions contemplated in the Merger Agreement (“Other Matters”) and (ii) at any meeting of the unitholders of
the 

  
 2 













 
Partnership, however called, and at every adjournment or postponement thereof (each, a “Meeting”), and on every other action or approval by written consent of the unitholders of
the Partnership, to the extent not voted by the Person(s) named (or otherwise appointed in the manner set forth in) the Consent Statement/Proxy Statement/Prospectus, vote (or cause to be voted), or cause the holder of record on any applicable record
date to vote, all Subject Partnership Units that are then beneficially owned by such Unitholder and entitled to vote or act by written consent: 

1.    in favor of the approval of the Merger Agreement, the Merger and any Other Matters; 

2.    in favor of the approval of any proposal to adjourn or postpone the Meeting to a later date, if there are not
sufficient votes for the approval of the Merger Agreement, the Merger or any Other Matter on the date on which such Meeting is held; 

3.    against the approval of any proposal made in opposition to, in competition with, or inconsistent with, the Merger
Agreement, the Merger or any Other Matter; and 
 4.    in favor of any other matter necessary or appropriate to the
consummation of the transactions contemplated by the Merger Agreement, including the Merger. 
 (b)    Any vote required
to be cast pursuant to this Section 3 shall be cast by the Unitholder or at the direction of the Unitholder, as applicable, in accordance with such procedures relating thereto so as to ensure that it is duly counted,
including for purposes of determining whether a quorum is present. 
 (c)    Except as provided herein, no Unitholder
shall (i) enter into any agreement or understanding with any Person to vote or give instructions in any manner inconsistent with the terms of this Section 3, (ii) grant at any time while this Agreement remains in
effect, a proxy, consent or power of attorney with respect to the Subject Partnership Units inconsistent with the terms of this Section 3 or (iii) take any action that would make any representation or warranty of such
Unitholder contained herein untrue or incorrect or have the effect of preventing or disabling such Unitholder from performing any of its obligations under this Agreement. 

(d)    The obligations of the Unitholder specified in Section 3(a) shall apply whether or not
the Merger or any action described above is recommended by the General Partner Board (or any committee thereof, including the GP Conflicts Committee), for so long as this Agreement is in effect. 

4.    Irrevocable Proxy. 

(a)    Solely in the event of a failure by any Unitholder to act in accordance with such Unitholder’s obligations as
to voting pursuant to Section 3(a) prior to the Expiration Date and without in any way limiting any Unitholder’s right to vote the Subject Partnership Units in its sole discretion on any other matters that may be
submitted to a unitholder vote, consent or other approval, each Unitholder hereby grants an irrevocable proxy (the “Proxy”) appointing Contango as such Unitholder’s attorney-in-fact and proxy, with full power of substitution, for and in such Unitholder’s name, to vote, express consent or dissent, or otherwise to utilize such


  
 3 













 
voting power in the manner contemplated by Section 3 above as Contango or its proxy or substitute shall, in Contango’s sole discretion, deem proper with respect to
the Subject Partnership Units. 
 (b)    Each Unitholder hereby represents that any proxies heretofore given in respect
of the Subject Partnership Units, if any, are revocable, and hereby revokes such proxies. 
 (c)    Each Unitholder
hereby affirms that its Proxy set forth in this Section 4 is given in connection with the execution of the Merger Agreement, and that such Proxy is given to secure the performance of the duties of such Unitholder under this
Agreement. Each Unitholder hereby further affirms that its Proxy is coupled with an interest in consideration of Contango entering into this Agreement and the Merger Agreement and incurring certain related fees and expenses and, except as set forth
in Section 4(d) or in Section 13 hereof, is intended to be, and is, irrevocable. All authority conferred hereby shall survive the death, incapacity of or the appointment of any liquidator,
receiver, trustee, special manager or any other court appointed officer for any Unitholder and shall be binding upon the heirs, estate, administrators, receivers, liquidators, trustees, special managers, personal representatives, successors and
assigns of each Unitholder. 
 (d)    Contango hereby acknowledges and agrees that the Proxy set forth in this
Section 4 shall not be exercised to vote, consent or act on any matter except as specifically contemplated by Section 3 above and Contango agrees not to exercise the Proxy granted herein for any
purpose other than the purposes described in Section 3. The Proxy set forth in this Section 4 shall be revoked, terminated and of no further force or effect automatically without further action
upon the termination of this Agreement. 
 5.    Update of Beneficial Ownership Information. Each Unitholder
shall promptly (and in any event within two Business Days after such acquisition) notify the Partnership and Contango of the number of Subject Partnership Units (i) acquired by such Unitholder following the date hereof and prior to the
Expiration Date and the updated number of Subject Partnership Units beneficially owned by such Unitholder as of immediately following such acquisition and (ii) disposed of in an Involuntary Transfer (including the identity of the transferee)
and the updated number of Subject Partnership Units beneficially owned by such Unitholder following such Involuntary Transfer. 

6.    Representations and Warranties of the Unitholders. Each Unitholder, severally and not jointly, hereby
represents and warrants to the Partnership and Contango as follows: 
 (a)    Power; Organization; Binding
Agreement. Such Unitholder has full power and authority to execute and deliver this Agreement and its Proxy, to perform such Unitholder’s obligations hereunder and to consummate the transactions contemplated hereby. If such
Unitholder is an entity, it is duly organized, validly existing and in good standing under the laws of its jurisdiction of formation. This Agreement has been duly executed and delivered by such Unitholder, and, assuming this Agreement constitutes a
valid and binding obligation of the Partnership and Contango, constitutes a valid and binding obligation of such Unitholder, enforceable against such Unitholder in accordance with its terms, except that such enforceability may be limited by
applicable bankruptcy, insolvency, moratorium, reorganization or similar Laws affecting the enforcement of creditors’ rights generally or by general principles of equity. 

  
 4 













 (b)    No Conflicts. None of the execution and delivery by
such Unitholder of this Agreement, the performance by such Unitholder of its obligations hereunder or the consummation by such Unitholder of the transactions contemplated hereby will (i) result in a violation or breach of any agreement to which
such Unitholder is a party or by which such Unitholder may be bound, including any voting agreement or voting trust, (ii) violate any applicable Law or (iii) violate the constituent or organizational document of such Unitholder. 

(c)    Ownership of Partnership Units. Such Unitholder is a beneficial owner of the Subject Partnership
Units set forth opposite such Unitholder’s name on Exhibit A, all of which are free and clear of any Liens (except any (x) Liens arising under securities Laws, (y) Liens arising hereunder or as permitted by
the Merger Agreement or (z) Liens that are not material to such Unitholder’s performance of its obligations under this Agreement). No Person (other than such Unitholder) has a right to acquire any of the Subject Partnership Units
beneficially owned by such Unitholder. 
 (d)    Voting Power. Such Unitholder has voting power, power of
disposition, power to issue instructions with respect to the matters set forth herein, and power to agree to all of the matters set forth in this Agreement, in each case with respect to all of the Subject Partnership Units beneficially owned by such
Unitholder, with no limitations, qualifications or restrictions on such rights, subject to applicable federal securities laws and those arising under the terms of this Agreement. 

(e)    Reliance by the Partnership and Contango. Such Unitholder understands and acknowledges that the Partnership
and Contango are entering into the Merger Agreement in reliance upon such Unitholder’s execution and delivery of this Agreement. 

(f)    Consents and Approvals. The execution and delivery of this Agreement by such Unitholder does not, and the
performance by such Unitholder of its obligations under this Agreement and the consummation by it of the transactions contemplated hereby will not, require such Unitholder to obtain any consent, approval, authorization or permit of, or to make any
filing with or notification to, any Governmental Entity, except in each case for filings with the SEC by such Unitholder or where the failure to obtain such consents, approvals, authorizations or permits, or to make such filings and notifications,
would not, either individually or in the aggregate, prevent or delay the performance by such Unitholder of any of its obligations hereunder. 

(g)    Absence of Litigation. As of the date hereof, there is no Action pending or, to the knowledge of such
Unitholder, threatened against or affecting such Unitholder or any of its Affiliates before or by any Governmental Entity that would reasonably be expected to impair the ability of such Unitholder to perform its obligations hereunder or to
consummate the transactions contemplated hereby on a timely basis. 
 7.    Certain Restrictions. 

(a)    Each Unitholder shall not, directly or indirectly, take any action that would make any representation or warranty of
such Unitholder contained herein untrue or incorrect in any respect. 

  
 5 













 (b)    Each Unitholder agrees that such Unitholder will not (in such
Unitholder’s capacity as a unitholder of the Partnership) bring, commence, institute, maintain, prosecute or voluntarily aid any legal action or proceeding, which (i) challenges the validity of or seeks to enjoin the operation of any
provision of this Agreement, (ii) alleges that the execution and delivery of this Agreement by such Unitholder, either alone or together with the other Partnership voting agreements and proxies to be delivered in connection with the execution
of the Merger Agreement, or the approval of the Merger Agreement and the Merger by the General Partner Board, breaches any fiduciary duty of the General Partner Board or any member thereof or (iii) would reasonably be expected to restrict or
otherwise affect such Unitholder’s legal power, authority and ability to comply with and perform its covenants and obligations under this Agreement. 

8.    No Solicitation. Except as set forth in this Section 8, during the term of this
Agreement, each Unitholder shall not, and shall not permit or authorize any of its respective Representatives, directly or indirectly, to (i) solicit, initiate, endorse, encourage or 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 (other than any Contango Party or any Mid-Con Party or any of their Affiliates)
any information or data with respect to, or otherwise cooperate in any way with, any Mid-Con Acquisition Proposal or (iii) resolve, agree or propose to do any of the foregoing. 

9.    Unitholder Capacity. The parties hereto acknowledge that this Agreement is being entered into by each
Unitholder solely in its capacity as a beneficial owner of the Subject Partnership Units, and nothing in this Agreement shall restrict or limit the ability of any Unitholder who is an officer or director of the General Partner or the Partnership (or
of any Affiliate thereof), to exercise his or her duties attendant to any such position by taking any action whatsoever in such capacity, including with respect to the Merger Agreement or this Agreement. 

10.    Disclosure. Each Unitholder shall permit Contango and the Partnership to publish and disclose in all
documents and schedules filed with the SEC, and any press release or other disclosure document that Contango and/or the Partnership determines to be necessary or desirable in connection with the Merger and any transactions related thereto, such
Unitholder’s identity and ownership of Subject Partnership Units and the nature of such Unitholder’s commitments, arrangements and understandings under this Agreement. 

11.    No Ownership Interest. Except as provided in this Agreement, nothing contained in this Agreement shall be
deemed to vest in the Partnership or Contango any direct or indirect ownership or incidence of ownership of or with respect to any Subject Partnership Units. Except as provided in this Agreement, all rights, ownership and economic benefits relating
to the Subject Partnership Units shall remain vested in and belong to the Unitholders. 
 12.    Further
Assurances. Subject to the terms and conditions of this Agreement, upon request of the Partnership or Contango, each Unitholder shall use commercially reasonable efforts to take, or cause to be taken, all actions, and to do, or cause to be done,
all things necessary to fulfill such Unitholder’s obligations under this Agreement. 

  
 6 













 13.    Termination. This Agreement and each Unitholder’s
Proxy, and all rights and obligations of the parties hereunder and thereunder, shall terminate and shall have no further force or effect as of the Expiration Date. Notwithstanding anything to the contrary in this Agreement, nothing set forth in this
Section 13 or elsewhere in this Agreement shall relieve any party hereto from liability, or otherwise limit the liability of any party hereto, for any willful breach of this Agreement prior to such termination. 

14.    Miscellaneous. 

(a)    Amendment or Supplement; Waiver. 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. At any time prior to the Effective Time,
any party may, to the extent permitted by and subject to applicable Law, waive compliance with any of the agreements or conditions of the other parties contained herein. 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. Notwithstanding anything to the contrary in this Agreement, any such amendment, modification, supplement or waiver of or to this
Agreement, or of or to any provision hereof, must be approved by the GP Conflicts Committee. No failure or delay of any party in exercising any right or remedy hereunder shall operate as a waiver thereof, nor shall any single or partial exercise of
any such right or power, or any abandonment or discontinuance of steps to enforce such right or power, or any course of conduct, preclude any other or further exercise thereof or the exercise of any other right or power. The rights and remedies of
the parties hereunder are cumulative and are not exclusive of any rights or remedies which they would otherwise have hereunder.
