 Exhibit 10.1 

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 “Shareholders” and each a “Shareholder”). 

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 Shareholder is the beneficial owner (as defined in Rule
13d-3 under the Securities Exchange Act of 1934, as amended) of the number of shares of Contango Common Stock set forth opposite such Shareholder’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 Shareholder (in such Shareholder’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 Shareholder ceases to be the beneficial owner of any shares of Contango Common
Stock without the consent of the Shareholder as a result of an any non-volitional transfer of Subject Contango Shares 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 Contango Shares occurring as a result of a dissolution, liquidation, reorganization, restructuring, bankruptcy, foreclosure, judicial sale or other event or transaction involving a
Shareholder or any entity through which Shareholder holds beneficial ownership of shares of Contango Common Stock, and that takes place without the action or consent of the Shareholder; or (ii) the Involuntary Transfer is caused by the
Shareholder, or any associate or affiliate of the Shareholder, 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 Contango Shares” shall mean, without duplication, (i) all
shares of Contango Common Stock of which such Shareholder is the record or beneficial owner as of the date hereof as set forth on Exhibit A attached hereto, (ii) all shares of Contango Common Stock issuable upon
conversion, exercise or exchange of options, warrants and/or other Rights to acquire shares of Contango Common Stock of which such Shareholder is the record or beneficial owner as of the date hereof and (iii) all additional shares of Contango
Common Stock, and all additional shares of Contango Common Stock issuable upon conversion, exercise or exchange of options, warrants and/or other Rights to acquire shares of Contango Common Stock, in each case of which such Shareholder acquires
record or beneficial ownership during the period from the date of this Agreement through the Expiration Date (including by way of share dividend or distribution, split-up, recapitalization, combination,
exchange of shares and the like). 
 (d) “Transfer.” A Person shall be deemed to have effected a “Transfer”
of a Subject Contango Share 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 Contango Share or any interest in such Subject Contango Share, (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 Contango Shares 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 Shareholder
shall Transfer (or cause or permit the Transfer of) any of its Subject Contango Shares, or enter into any agreement relating thereto, except with the Partnership’s prior written consent and in the Partnership’s sole discretion. If any
Involuntary Transfer of any of such Shareholder’s Subject Contango Shares 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 Contango Shares 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 Contango Common Stock. 

(a) Prior to the Expiration Date, each Shareholder (in such Shareholder’s capacity as such) irrevocably and unconditionally agrees that it
shall (i) if the Contango Shareholder Approval is to be sought by the Contango Written Consent pursuant to Section 5.4(c)(ii) of the Merger Agreement, promptly after the execution of this Agreement and the delivery to such Shareholder of a
form of Contango Written Consent, deliver (or cause to be delivered) a written consent pursuant to Section 2.12 of the Contango Bylaws covering all of the Subject Contango Shares that are then beneficially owned by such Shareholder approving
the Contango Stock Issuance and any other matters presented or proposed as to the approval of, or any other transactions contemplated in connection with, the Contango Stock Issuance (“Other Matters”) and (ii) at any meeting of
the shareholders of Contango, however called, and at every 

  
 2 












 
adjournment or postponement thereof (each, a “Meeting”), and on every other action or approval by written consent of the shareholders of Contango, 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 Contango Shares that
are then beneficially owned by such Shareholder and entitled to vote or act by written consent: 
 1. in favor of the approval of the
Contango Stock Issuance 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 Contango Stock Issuance 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 Contango Stock Issuance 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 Contango Stock Issuance. 
 (b) Any vote required to be cast pursuant to this
Section 3 shall be cast by the Shareholder or at the direction of the Shareholder, 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 Shareholder 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 Contango Shares inconsistent with the terms of this Section 3 or (iii) take any action that would make any representation or warranty of such Shareholder contained herein untrue or
incorrect or have the effect of preventing or disabling such Shareholder from performing any of its obligations under this Agreement. 
 (d)
The obligations of the Shareholder specified in Section 3(a) shall apply whether or not the Contango Stock Issuance or any action described above is recommended by the Contango Board (or any committee thereof), for so long
as this Agreement is in effect. 
 4. Irrevocable Proxy. 

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

  
 3 












 (b) Each Shareholder hereby represents that any proxies heretofore given in respect of the
Subject Contango Shares, if any, are revocable, and hereby revokes such proxies. 
 (c) Each Shareholder 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 Shareholder under this Agreement. Each Shareholder
hereby further affirms that its Proxy is coupled with an interest in consideration of the Partnership 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 Shareholder and shall be binding upon the heirs, estate, administrators, receivers, liquidators, trustees, special managers, personal representatives, successors and assigns of
each Shareholder. 
 (d) The Partnership 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 the Partnership 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 Shareholder shall promptly (and in any event within two Business
Days after such acquisition) notify the Partnership and Contango of the number of Subject Contango Shares (i) acquired by such Shareholder following the date hereof and prior to the Expiration Date and the updated number of Subject Contango
Shares beneficially owned by such Shareholder 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 Contango Shares beneficially
owned by such Shareholder following such Involuntary Transfer. 
 6. Representations and Warranties of the Shareholders. Each
Shareholder, severally and not jointly, hereby represents and warrants to the Partnership and Contango as follows: 
 (a) Power;
Organization; Binding Agreement. Such Shareholder has full power and authority to execute and deliver this Agreement and its Proxy, to perform such Shareholder’s obligations hereunder and to consummate the transactions contemplated
hereby. If such Shareholder 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 Shareholder, and, assuming this
Agreement constitutes a valid and binding obligation of the Partnership and Contango, constitutes a valid and binding obligation of such Shareholder, enforceable against such Shareholder 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 Shareholder of
this Agreement, the performance by such Shareholder of its obligations hereunder or the consummation by such Shareholder of the transactions contemplated hereby will (i) result in a violation or breach of any agreement to which such Shareholder
is a party or by which such Shareholder 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 Shareholder. 

(c) Ownership of Contango Common Stock. Such Shareholder is a beneficial owner of the Subject Contango Shares set forth
opposite such Shareholder’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 Shareholder’s performance of its obligations under this Agreement). No Person (other than such Shareholder) has a right to acquire any of the Subject Contango Shares beneficially owned
by such Shareholder. 
 (d) Voting Power. Such Shareholder 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 Contango Shares beneficially owned by such Shareholder, 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 Shareholder understands and acknowledges that the Partnership and Contango are
entering into the Merger Agreement in reliance upon such Shareholder’s execution and delivery of this Agreement. 
 (f) Consents and
Approvals. The execution and delivery of this Agreement by such Shareholder does not, and the performance by such Shareholder of its obligations under this Agreement and the consummation by it of the transactions contemplated hereby will not,
require such Shareholder 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 Shareholder 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 Shareholder 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 Shareholder, threatened
against or affecting such Shareholder or any of its Affiliates before or by any Governmental Entity that would reasonably be expected to impair the ability of such Shareholder to perform its obligations hereunder or to consummate the transactions
contemplated hereby on a timely basis. 
 7. Certain Restrictions. 

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

  
 5 












 (b) Each Shareholder agrees that such Shareholder will not (in such Shareholder’s
capacity as a shareholder of Contango) 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 Shareholder, either alone or together with the other Contango voting agreements and proxies to be delivered in connection with the execution of the Merger Agreement and the
Contango Stock Issuance, or the approval of the Merger Agreement and the Merger by the Contango Board, breaches any fiduciary duty of the Contango Board or any member thereof or (iii) would reasonably be expected to restrict or otherwise affect
such Shareholder’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 Shareholder
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 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 (other than any Contango Party or any Michael Party or any of their Affiliates) 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. 
 9. Shareholder Capacity. The parties hereto acknowledge that this Agreement is being entered
into by each Shareholder solely in its capacity as a beneficial owner of the Subject Contango Shares, and nothing in this Agreement shall restrict or limit the ability of any Shareholder who is an officer or director of Contango (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 Shareholder 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, the Contango Stock Issuance and any transactions related thereto, such
Shareholder’s identity and ownership of Subject Contango Shares and the nature of such Shareholder’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 Contango Shares. Except as provided in this Agreement, all rights, ownership and economic benefits relating to the Subject Contango
Shares shall remain vested in and belong to the Shareholders. 
 12. Further Assurances. Subject to the terms and conditions of this
Agreement, upon request of the Partnership or Contango, each Shareholder 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 Shareholder’s
obligations under this Agreement. 

  
 6 












 13. Termination. This Agreement and each Shareholder’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. 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. The obligations of each Shareholder hereunder shall be several and not joint, and no Shareholder shall be liable for any breach of the terms of this Agreement by any other Shareholder.
