ARTICLE III 

REPRESENTATIONS AND WARRANTIES AND 

COVENANTS RELATED TO CONTANGO 

Contango represents and warrants to and covenants with each Purchaser as follows: 

Section 3.01 Corporate Existence. Contango has been duly incorporated and is validly existing as a corporation in
good standing under the laws of the State of Texas, with full corporate power and authority to own, lease and operate its properties and assets and conduct its business as described in the SEC Reports, to execute and deliver this Agreement and to
issue, sell and deliver the Purchased Securities as contemplated herein. Contango is duly qualified to do business as a foreign corporation and is in good standing in each jurisdiction where the ownership or leasing of its properties and assets or
the conduct of its business requires such qualification, except where the failure to be so qualified and in good standing would not, individually or in the aggregate, reasonably be expected to either (i) have a material adverse effect on the
business, properties, condition (financial or otherwise), liquidity, results of operations or prospects of Contango and the Subsidiaries taken as a whole or (ii) prevent or materially interfere with consummation of the transactions contemplated
hereby (the occurrence of any such effect or any such prevention or interference described in the foregoing clauses (i) and (ii) being herein referred to as a “Material Adverse Effect”). 

Section 3.02 Subsidiaries. Contango owns, directly or indirectly, the issued and outstanding capital stock,
membership interests, partnership interests or other ownership interests (as applicable) of each of the entities listed on Schedule B hereto in the percentages set forth on Schedule B hereto, which constitute all
direct or indirect subsidiaries of Contango. References herein to “Subsidiaries” refer to the entities listed on Schedule B hereto. Each Subsidiary has been duly organized and is validly existing and in good standing under
the laws of the jurisdiction of its organization, with full power and authority to own, lease and operate its properties and assets and to conduct its business as described in the SEC Reports, except where the failure to be in good standing would
not have a Material Adverse Effect. Each Subsidiary is duly qualified to do business and is in good standing in each jurisdiction where the ownership or leasing of its properties and assets or the conduct of its business requires such qualification,
except where the failure to be so qualified and in good standing would not, individually or in the aggregate, have a Material Adverse Effect. Except as disclosed in the SEC Reports, all of the outstanding shares of

  
 7 

 
capital stock of, or other equity interests in, each of the Subsidiaries have been duly authorized and validly issued, are fully paid
and non-assessable, have been issued in compliance with all applicable securities laws, were not issued in violation of any preemptive right, resale right, right of first refusal or similar right and
are owned by Contango or applicable Subsidiary subject to no security interest, other encumbrance or adverse claims, except for such liens, encumbrances, equities or claims granted in connection with that certain Credit Agreement, dated as of
September 17, 2019, among Contango, as borrower, JPMorgan Chase Bank, N.A., as administrative agent, and each of JPMorgan Chase Bank, N.A., Royal Bank of Canada and Cadence Bank, N.A., as joint bookrunners and the lenders from time to time
party thereto, and as amended, restated or modified from time to time (collectively, the “Credit Agreement”), or as could not, in the aggregate, reasonably be expected to have a Material Adverse Effect. No options, warrants or other
rights to purchase, agreements or other obligations to issue or other rights to convert any obligation into shares of capital stock of, or equity interests in, the Subsidiaries are outstanding. Contango owns, directly or indirectly, 37% of the
outstanding limited liability company interests in Exaro Energy III LLC, a Delaware limited liability company, and such limited liability company interests are owned by Contango subject to no security interest, other encumbrance or adverse claims,
except for such liens, encumbrances, equities or claims granted in connection with the Credit Agreement or as could not, in the aggregate, reasonably be expected to have a Material Adverse Effect. 

Section 3.03 Capitalization. As of the date of this Agreement, Contango has 200,000,000 shares of Common Stock and
5,000,000 shares of preferred stock authorized and, prior to the issuance and sale of the Purchased Securities as contemplated hereby and assuming conversion of all outstanding shares of the Company’s Series A Contingent Convertible Preferred
Stock and Series B Contingent Convertible Preferred Stock, has 108,334,045 shares of Common Stock issued and outstanding. All of the issued and outstanding shares of capital stock of Contango have been duly authorized and validly issued and are
fully paid and non-assessable, have been issued in compliance with all applicable securities laws and were not issued in violation of any preemptive right, resale right, right of first refusal or
similar right. 
 Section 3.04 Listing. The Common Stock is duly listed, and admitted and authorized for
trading, on the NYSE American. Contango has not received any notice from the NYSE American regarding the delisting or potential delisting of the Common Stock from the NYSE American. Concurrently with the Closing, Contango shall apply to list or
quote all of the Purchased Securities on the NYSE American and promptly secure the listing of all of the Purchased Securities. Contango hereby agrees to use commercially reasonable efforts to maintain the listing or quotation of the Common Stock,
including the Purchased Securities when listed, on the NYSE American and will comply in all respects with Contango’s reporting, filing and other obligations under the rules and regulations of the NYSE American. Contango further agrees, if
Contango applies to have the Common Stock traded on any other trading market, it will then include in such application all of the Purchased Securities, and will take such other action as is necessary to cause all of the Purchased Securities to be
listed or quoted on such other trading market as promptly as possible. For so long as Contango maintains a listing or quotation of the Common Stock on the NYSE American or any other trading market, Contango agrees to maintain the eligibility of the
Common Stock for electronic transfer through the Depository Trust Company or another established clearing corporation, including, without limitation, by timely payment of fees to the Depository Trust Company or such other established clearing
corporation in connection with such electronic transfer. 

  
 8 

 Section 3.05 Valid Issuance of Purchased Securities. The
Purchased Securities have been duly and validly authorized and, when issued and delivered against payment therefor as provided herein, will be duly and validly issued, fully paid
and non-assessable and free of statutory and contractual preemptive rights, resale rights, rights of first refusal and similar rights and any restriction upon the voting or transfer thereof pursuant

conformity with U.S. generally accepted accounting principles (“GAAP”) applied on a consistent basis during the periods involved. The other financial and statistical data included or incorporated by reference in the SEC

  
 10 

 
Reports are accurately and fairly presented in all material respects and are prepared on a basis consistent with the financial statements and books and records of Contango. Other than in
connection with the acquisition of certain assets and liabilities from White Star Petroleum, LLC and certain of its affiliates (the “White Star Properties”), Contango and the Subsidiaries do not have any material liabilities or
obligations, direct or contingent (including any off-balance sheet obligations), not described or incorporated by reference in the SEC Reports. All disclosures included or incorporated by reference in the SEC
Reports regarding “non-GAAP financial measures” (as such term is defined by the rules and regulations of the SEC) comply with Regulation G under the Exchange Act and Item 10 of Regulation S-K under the Securities Act, to the extent applicable. The interactive data in eXtensible Business Reporting Language included or incorporated by reference in the SEC Reports fairly presents the information called

Section 3.12 Internal Controls. Contango and each of its Subsidiaries maintain effective internal control over
financial reporting (as defined in Rules 13a-15 and 15d-15 under the Exchange Act) and a system of internal accounting controls sufficient to provide reasonable
assurance that: (i) transactions are executed in accordance with management’s general or specific authorization; (ii) transactions are recorded as necessary to permit preparation of financial statements in conformity with GAAP and to
maintain accountability for assets; (iii) access to assets is permitted only in accordance with management’s general or specific authorization; and (iv) the recorded accountability for assets is compared with existing assets at
reasonable intervals and appropriate action is taken with respect to any differences. Contango’s independent registered public accountants and the Audit Committee of the Board of Directors of Contango have been advised of (1) all
significant deficiencies and material weaknesses, if any, in the design or operation of Contango’s internal control over financial reporting (whether or not remediated) and (2) all fraud, if any, whether or not material, that involves
management or other employees who have a role in Contango’s internal control over financial reporting. All significant deficiencies and material weaknesses, if any, in Contango’s internal control over financial reporting are disclosed SEC
Reports. Since the end of Contango’s most recent audited fiscal year, except as disclosed in the SEC Reports, there have not been any changes in Contango’s internal control over financial reporting that have materially affected, or are
reasonably likely to materially affect, the Contango’s internal control over financial reporting. 
 Section 3.13
Disclosure Controls. Contango and each of its Subsidiaries maintain effective disclosure controls and procedures (as defined in Rules 13a-15 and 15d-15 under the
Exchange Act) designed to ensure that information required to be disclosed by Contango in the reports it files or submits under the Exchange Act is recorded, processed, summarized and reported, within the time period specified in the SEC’s
rules and forms, and is accumulated and communicated to management of Contango, including its principal executive officer and its principal financial officer, as appropriate, to allow timely decisions regarding disclosure.

 12 

 
Credit Agreement, (iii) liens and encumbrances under operating agreements, unitization and pooling agreements, production sales

other unmatured obligations and are of a scope and nature customary in the oil and gas industry or arise in connection with drilling and production operations, or (iv) would not, in the aggregate, have a Material Adverse Effect. Except as would
not, in the aggregate, reasonably be expected to have a Material Adverse Effect or as described in the SEC Reports, all of the oil and gas leases of Contango or any of the Subsidiaries and under which Contango or any of the Subsidiaries holds
properties described in the SEC Reports, are in full force and effect, and neither Contango nor any of the Subsidiaries has received written notice of any claim of any sort that has been asserted by anyone adverse to the rights of Contango or any of

aggregate, a Material Adverse Effect.

(i) all royalties, rentals, deposits and other amounts owed under the oil and gas leases constituting the oil and gas properties of Contango and the Subsidiaries have been properly and timely paid (other than amounts held in suspense accounts

amount of proceeds from the sale or production attributable to the oil and gas properties of Contango and the Subsidiaries are currently being held in suspense by any purchaser thereof, except where such amounts due would not reasonably be expected
to have a Material Adverse Effect, and (ii) there are no claims under take-or-pay contracts pursuant to which natural gas purchasers have any makeup
rights affecting the interests of Contango or the Subsidiaries in their respective oil and gas properties, except where such claims would not reasonably be expected to have a Material Adverse Effect. 

Section 3.21 Intellectual Property. Each of Contango and the Subsidiaries owns, licenses or otherwise has the
right to use all inventions, patent applications, patents, trademarks (both registered and unregistered), trade names, service names, know-how (including trade secrets and other unpatented and/or
unpatentable proprietary or confidential information, systems or procedures), copyrights, service marks and other intellectual property as described in the SEC Reports and which is necessary for the conduct of, or material to, its business

 Section 3.23 Environmental Matters. Contango
and the Subsidiaries and their respective properties, assets and operations are in compliance with, and Contango and each of the Subsidiaries hold all permits, authorizations and approvals required under, Environmental Laws (as defined below),
except to the extent that failure to so comply or to hold such permits, authorizations or approvals would not, individually or in the aggregate, have a Material Adverse Effect. There are no past or present conditions, circumstances, activities,
practices, actions, omissions or plans that could reasonably be expected to give rise to any material costs or liabilities to Contango or any Subsidiary under, or to interfere with or prevent compliance by Contango or any Subsidiary with,

transactions contemplated hereby, whether written or oral, between Contango, any of its Subsidiaries or any of their respective officers, directors, agents, employees or Affiliates on the one hand, and any of the Purchasers or any of their
Affiliates on the other hand, shall terminate. Contango and each Purchaser shall consult with each other in issuing any other press releases with respect to the transactions contemplated hereby, and neither Contango nor any Purchaser shall issue any
such press release nor otherwise make any such public statement without the prior consent of Contango, with respect to any press release of any Purchaser, or without the prior consent of each Purchaser, with respect to any press release of Contango,
which consent shall not unreasonably be withheld or delayed, except if such disclosure is required by law, in which case the disclosing party shall promptly provide the other party with prior notice of such public statement or communication.
Notwithstanding the foregoing, Contango shall not publicly disclose the name of any Purchaser, or include the name of any Purchaser in any filing with the SEC or any regulatory agency or NYSE American, without the prior written consent of such
Purchaser, except (a) as required by federal securities law in connection with the filing of the Basic Documents with the SEC and (b) to the extent such disclosure is required by law or NYSE American regulations, in which case Contango
shall provide the Purchasers with prior notice of such disclosure permitted under this clause (b). 
 Section 3.42
Information on Shareholdings. After the Closing, Contango shall promptly and accurately respond, and shall use its commercially reasonable efforts to cause its transfer agent to respond, to reasonable requests for information (which is
otherwise not publicly available) made by a Purchaser or its auditors relating to the actual holdings of such Purchaser or its accounts; provided that Contango shall not be obligated to provide any information that could reasonably result in a
violation of applicable law or conflict with Contango’s insider trading policy or a confidentiality obligation of the Contango. 

Section 3.43 Removal of Legend. In connection with a sale of the Purchased Securities by a Purchaser in reliance
on Rule 144, the applicable Purchaser or its broker shall deliver to the transfer agent and Contango a seller or broker representation letter, as applicable, providing to the transfer agent and Contango any information deemed reasonably necessary to
determine that the sale of the Purchased Securities is made in compliance with Rule 144, including, as may be appropriate, a certification that the Purchaser is not an Affiliate of Contango and regarding the length of time the Purchased Securities
have been held. Upon receipt of such representation letter, Contango shall promptly direct its transfer agent to remove the notation of a restrictive legend in such Purchaser’s book-entry account maintained by the transfer agent, including the
legend referred to in Section 4.05(d), and Contango shall bear all costs associated therewith. After a registration statement under the Securities Act permitting the public resale of the Purchased Securities has become effective or any
Purchaser or its permitted assigns have held the Purchased Securities for one year, if the book-entry account of such Purchased Securities still bears the notation of the restrictive legend referred to in Section 4.05(d), Contango agrees, upon
request of 

  
 19 

 
the Purchaser or permitted assignee, to take all steps necessary to promptly effect the removal of the legend described in Section 4.05(d) from the Purchased Securities, and Contango shall
bear all costs associated therewith, regardless of whether the request is made in connection with a sale or otherwise, so long as such Purchaser or its permitted assigns provide to Contango any information deemed reasonably necessary to determine
that the legend is no longer required under the Securities Act or applicable state laws, including (if there is no such registration statement) a certification that the holder is not an Affiliate of Contango and regarding the length of time the
Purchased Securities have been held. 
 ARTICLE IV 

REPRESENTATIONS AND WARRANTIES AND 

COVENANTS OF THE PURCHASERS 

Each Purchaser, severally and not jointly, hereby represents and warrants and covenants to Contango as follows: 

Section 4.01 Existence. Such Purchaser is duly organized and validly existing and in good standing under the laws
of its state of formation, with all necessary power and authority to own properties and to conduct its business as currently conducted. 

Section 4.02 Authorization, Enforceability. Such Purchaser has all necessary legal power and authority to execute,
deliver and perform its obligations under the Basic Documents to which such Purchaser is or will be a party. The execution, delivery and performance by such Purchaser of the Basic Documents to which such Purchaser is or will be a party and the
consummation by it of the transactions contemplated hereby and thereby have been duly and validly authorized by all necessary legal action, and no further consent or authorization of such Purchaser is required. This Agreement to which such Purchaser
is a party has been duly and validly authorized, executed and delivered by such Purchaser and constitutes the legal, valid and binding obligation of such Purchaser and, when executed by such Purchaser, the other Basic Documents to which such
Purchaser is a party will be duly and validly authorized, executed and delivered by such Purchaser and will constitute the legal, valid and binding obligations of such Purchaser, in each case enforceable in accordance with their terms, except as
such enforceability may be limited by bankruptcy, insolvency, fraudulent transfer and similar laws affecting creditors’ rights generally or by general principles of equity and except as the rights to indemnification may be limited by applicable
law. 
 Section 4.03 No Breach. The execution, delivery and performance by such Purchaser of the Basic Documents
and the consummation by such Purchaser of the transactions contemplated hereby or thereby does not and will not (a) assuming the accuracy of the representations and warranties of Contango contained herein and its compliance with the covenants
contained herein, violate any provision of any Law or permit having applicability to such Purchaser or the property or assets of such Purchaser, (b) conflict with or result in a violation or breach of any provision of the organizational
documents of such Purchaser, or (c) conflict with or result in a breach or violation of any of the terms or provisions of, or constitute a default under, any material agreement to which such Purchaser is a party or by which such Purchaser is
bound or to which any of the property or assets of such Purchaser is subject, except in the case of clauses (a) and (c), for such conflicts, breaches, violations or defaults as would not have a material adverse effect on the ability of such
Purchaser to consummate the transactions contemplated by the Basic Documents. 

  
 20 

 Section 4.04 Certain Fees. No fees or commissions are or will be
payable by such Purchaser to brokers, finders or investment bankers with respect to the purchase of any of the Purchased Securities or the consummation of the transactions contemplated by this Agreement. 

Section 4.05 Unregistered Securities. 

(a) Accredited Investor Status; Sophisticated Purchasers. Such Purchaser is an “accredited investor” within
the meaning of Rule 501 under the Securities Act and is able to bear the risk of its investment in Purchased Securities. Such Purchaser has such knowledge and experience in financial and business matters that it is capable of evaluating the merits
and risks of the purchase of the Purchased Securities. 
 (b) Information. Such Purchaser and its Representatives have
been furnished with all materials relating to the business, finances and operations of Contango that have been requested and materials relating to the offer and sale of the Purchased Securities that have been requested by such Purchaser and its
Representatives. Such Purchaser and its Representatives have been afforded the opportunity to ask questions of Contango. Neither such inquiries nor any other due diligence investigations conducted at any time by such Purchaser and its
Representatives shall modify, amend or affect such Purchaser’s right (i) to rely on Contango’s representations and warranties contained in Article III above or (ii) to indemnification or any other remedy based on, or with
respect to the accuracy or inaccuracy of, or compliance with, the representations, warranties, covenants and agreements in this Agreement, or any other Basic Document. Such Purchaser understands that the purchase of the Purchased Securities involves
a high degree of risk. Such Purchaser has sought such accounting, legal and tax advice as it has considered necessary to make an informed investment decision with respect to its acquisition of the Purchased Securities. 

(c) Cooperation. Such Purchaser shall cooperate reasonably with Contango to provide any information necessary for any
applicable securities filings required to be made by Contango in connection with the transactions contemplated hereby. 
 (d)
Legends. Such Purchaser understands that the Purchased Securities will bear a restrictive legend substantially in the form as set forth below: 

THE SECURITIES REPRESENTED HEREBY HAVE NOT BEEN REGISTERED UNDER THE SECURITIES ACT OF 1933, AS AMENDED (THE “SECURITIES
ACT”), OR ANY STATE SECURITIES LAWS. THESE SECURITIES MAY NOT BE REOFFERED, SOLD, ASSIGNED, TRANSFERRED, PLEDGED, ENCUMBERED OR OTHERWISE DISPOSED OF IN THE ABSENCE OF SUCH REGISTRATION OR UNLESS SUCH TRANSACTION IS EXEMPT FROM, OR NOT SUBJECT
TO, REGISTRATION. 

  
 21 

 (e) Purpose of Purchase. Such Purchaser is purchasing the Purchased
Securities for its own account and not with a view to distribution in violation of any securities laws. Such Purchaser has been advised and understands that the Purchased Securities have not been registered under the Securities Act or under the
“blue sky” laws of any jurisdiction and may be resold only if registered pursuant to the provisions of the Securities Act (or if eligible, pursuant to the provisions of Rule 144 promulgated under the Securities Act or pursuant to another
available exemption from the registration requirements of the Securities Act). 
 (f) Rule 144. Such Purchaser
understands that the Purchased Securities must be held indefinitely unless and until the Purchased Securities are registered for resale under the Securities Act or an exemption from such registration is available. Such Purchaser has been advised by
its advisors of and is aware of the provisions of Rule 144 promulgated under the Securities Act. 
 (g) Reliance by
Contango. Such Purchaser understands that the Purchased Securities are being offered and sold in reliance on transactional exemptions from the registration requirements of federal and state securities laws and that Contango is relying upon the
truth and accuracy of the representations, warranties, covenants, acknowledgments and understandings of such Purchaser set forth herein in order to determine the applicability of such exemptions and the suitability of such Purchaser to acquire the
Purchased Securities. 
 Section 4.06 No Legal, Tax or Investment Advice. Such Purchaser understands that
nothing in this Agreement or any other materials presented by or on behalf of Contango to the Purchaser in connection with the offer and sale of the Purchased Securities constitutes legal, tax or investment advice. Such Purchaser has consulted such
legal, tax and investment advisors as it, in its sole discretion, has deemed necessary or appropriate in connection with its purchase of the Purchased Securities. Such Purchaser understands that Cowen and Company LLC and Intrepid Partners, LLC (the
“Placement Agents”) have acted solely as the agents of Contango in this placement of the Purchased Securities, and that the Placement Agents make no representation or warranty with regard to the merits of this transaction or as to
the accuracy of any information such Purchaser may have received in connection therewith. Such Purchaser acknowledges that it has not relied on any information or advice furnished by or on behalf of the Placement Agents. 

Section 4.07 Short Selling. Such Purchaser has not engaged in any Short Sales involving Common Stock owned by it
between the time it first began discussions with Contango about the transaction contemplated by this Agreement and the date of execution of this Agreement. 

ARTICLE V 

INDEMNIFICATION 

Section 5.01 Indemnification by Contango. Contango agrees to indemnify each Purchaser and its
Representatives (collectively, “Purchaser Related Parties”) from, and hold each of them harmless against, any and all losses, actions, suits, proceedings (including any investigations, litigation or inquiries), demands and causes of
action, and, in connection therewith, and promptly upon demand, pay or reimburse each of them for all reasonable costs, losses, liabilities, damages or expenses of any kind or nature whatsoever (including the reasonable fees and disbursements of
counsel and all other reasonable expenses incurred in connection with 

  
 22 

 
investigating, defending or preparing to defend any such matter that may be incurred by them or asserted against or involve any of them), involving a third party claim, as a result of, arising
out of, or in any way related to (i) the failure of any of the representations or warranties made by Contango contained herein to be true and correct in all material respects as of the date hereof (except with respect to any provisions
including the word “material” or words of similar import, with respect to which such representations and warranties must have been true and correct) or (ii) the material breach of any covenants of Contango contained herein,
provided that, in the case of the immediately preceding clause (i), such claim for indemnification is made prior to the expiration of such representation or warranty; provided, however, that for purposes of determining when an
indemnification claim has been made, the date upon which a Purchaser Related Party shall have given notice (stating in reasonable detail the basis of the claim for indemnification) to Contango shall constitute the date upon which such claim has been
made. 
 Section 5.02 Indemnification by the Purchasers. Each Purchaser agrees, severally and not jointly, to
indemnify Contango and its respective Representatives (collectively, “Contango Related Parties”) from, and hold each of them harmless against, any and all losses, actions, suits, proceedings (including any investigations,
litigation or inquiries), demands and causes of action, and, in connection therewith, and promptly upon demand, pay or reimburse each of them for all reasonable costs, losses, liabilities, damages or expenses of any kind or nature whatsoever
(including the reasonable fees and disbursements of counsel and all other reasonable expenses incurred in connection with investigating, defending or preparing to defend any such matter that may be incurred by them or asserted against or involve any
of them), involving a third party claim, as a result of, arising out of, or in any way related to (i) the failure of any of the representations or warranties made by such Purchaser contained herein to be true and correct in all material
respects as of the date hereof or (ii) the material breach of any of the covenants of such Purchaser contained herein, provided that, in the case of the immediately preceding clause (i), such claim for indemnification relating to a
breach of any representation or warranty is made prior to the expiration of such representation or warranty; provided, however, that for purposes of determining when an indemnification claim has been made, the date upon which a
Contango Related Party shall have given notice (stating in reasonable detail the basis of the claim for indemnification) to such Purchaser shall constitute the date upon which such claim has been made; provided, further, that the
liability of such Purchaser shall not be greater in amount than such Purchaser’s Allocated Purchase Price. 

Section 5.03 Indemnification Procedure. A claim for indemnification for any matter not involving a third party
claim may be asserted by notice to the party from whom indemnification is sought; provided, however, that failure to so notify the Indemnifying Party shall not preclude the Indemnified Party from any indemnification which it may claim
in accordance with this Article V, except as otherwise provided in Sections 5.01 and 5.02. Promptly after any Contango Related Party or Purchaser Related Party (hereinafter, the “Indemnified Party”) has received
notice of any indemnifiable claim hereunder, or the commencement of any action, suit or proceeding by a third Person, which the Indemnified Party believes in good faith is an indemnifiable claim under this Agreement, the Indemnified Party shall give
the indemnitor hereunder (the “Indemnifying Party”) written notice of such claim or the commencement of such action, suit or proceeding, but failure 

  
 23 

 
to so notify the Indemnifying Party will not relieve the Indemnifying Party from any liability it may have to such Indemnified Party hereunder except to the extent that the Indemnifying Party is
materially prejudiced by such failure. Such notice shall state the nature and the basis of such claim to the extent then known. The Indemnifying Party shall have the right to defend and settle, at its own expense and by its own counsel, any such
matter as long as the Indemnifying Party pursues the same diligently and in good faith. If the Indemnifying Party undertakes to defend or settle such claim, it shall promptly after such determination, and in no event later than five (5) days,
notify the Indemnified Party of its intention to do so, and the Indemnified Party shall cooperate with the Indemnifying Party and its counsel in all commercially reasonable respects in the defense thereof and/or the settlement thereof. Such
cooperation shall include, but shall not be limited to, furnishing the Indemnifying Party with any books, records and other information reasonably requested by the Indemnifying Party and in the Indemnified Party’s possession or control relevant
to the claim. Such cooperation of the Indemnified Party shall be at the cost of the Indemnifying Party. After the Indemnifying Party has notified the Indemnified Party of its intention to undertake to defend or settle any such asserted liability,
and for so long as the Indemnifying Party diligently pursues such defense, the Indemnifying Party shall not be liable for any additional legal expenses incurred by the Indemnified Party in connection with any defense or settlement of such asserted
liability; provided, however, that the Indemnified Party shall be entitled (i) at its expense, to participate in the defense of such asserted liability and the negotiations of the settlement thereof and (ii) if (A) the
Indemnifying Party has, within ten (10) Business Days of when the Indemnified Party provides written notice of a claim, failed (y) to assume the defense or settlement of such claim and employ counsel or (z) to notify the Indemnified
Party of such assumption, or (B) if the defendants in any such action include both the Indemnified Party and the Indemnifying Party and counsel to the Indemnified Party shall have concluded that there may be reasonable defenses available to the
Indemnified Party that are different from or in addition to those available to the Indemnifying Party or if the interests of the Indemnified Party reasonably may be deemed to conflict with the interests of the Indemnifying Party, then the
Indemnified Party shall have the right to select a separate counsel and to assume such legal defense and otherwise to participate in the defense of such action, with the expenses and fees of such separate counsel and other expenses related to such
participation to be reimbursed by the Indemnifying Party as incurred. Notwithstanding any other provision of this Agreement, the Indemnifying Party shall not settle any indemnified claim without the consent of the Indemnified Party, unless the
settlement thereof imposes no liability or obligation on, and includes a complete release from liability of, and does not contain any admission of wrong doing by, the Indemnified Party. 

Section 5.04 Tax Treatment of Indemnification Payments. Any indemnification payments made under this Article
V shall be treated for all tax purposes as an adjustment to the relevant Purchaser’s Allocated Purchase Price except as otherwise required by applicable Law. 

ARTICLE VI 
 TERMINATION

 Section 6.01 Termination. Notwithstanding anything in this Agreement to the contrary, this Agreement may
be terminated at any time: 

  
 24 

 (a) by any Purchaser (with respect to the obligations of such Purchaser) or
Contango, upon written notice to the other party, if the Closing shall not have occurred on or before December 27, 2019 (the “Outside Date”); provided, however, that the right to terminate this Agreement under this
Section 6.01(a) shall not be available to any party whose (i) breach of any provision of this Agreement, (ii) failure to comply with its obligations under this Agreement or (iii) actions not taken in good faith shall have been
the cause of, or shall have resulted in, the failure of the Closing to occur on or prior to the Outside Date or the failure of a condition in Section 2.04(b) or Section 2.04(c) to be satisfied at such time; or 

(b) by either Contango or any Purchaser (with respect to the obligations of such Purchaser) if any court of competent
jurisdiction in the United States or other United States Regulatory Authority shall have issued a final order, decree or ruling or taken any other final action restraining, enjoining or otherwise prohibiting the transactions contemplated hereby and
such order, decree, ruling or other action is or shall have become final and nonappealable. 
 Section 6.02 Certain
Effects of Termination. If this Agreement is terminated as provided in Section 6.01, except as set forth in Section 7.03, this Agreement shall become null and void and have no further force or
effect, but the parties shall not be released from any liability arising from or in connection with any breach hereof occurring prior to such termination. 

ARTICLE VII 

MISCELLANEOUS 

Section 7.01 Expenses. All other costs and expenses, including, without limitation, fees and disbursements of
counsel, financial advisors and accountants, incurred in connection with this Agreement and the transactions contemplated hereby shall be paid by the party incurring such costs and expenses, whether or not the Closing shall have occurred. 

Section 7.02 Interpretation. Article, Section, Schedule and Exhibit references in this Agreement are references to
the corresponding Article, Section, Schedule or Exhibit to this Agreement, unless otherwise specified. All Exhibits and Schedules to this Agreement are hereby incorporated and made a part hereof as if set forth in full herein and are an integral
part of this Agreement. All references to instruments, documents, contracts and agreements are references to such instruments, documents, contracts and agreements as the same may be amended, supplemented and otherwise modified from time to time,
unless otherwise specified. The word “including” shall mean “including but not limited to” and shall not be construed to limit any general statement that it follows to the specific or similar items or matters immediately
following it. Whenever Contango has an obligation under the Basic Documents, the expense of complying with that obligation shall be an expense of Contango unless otherwise specified. Any reference in this Agreement to $ shall mean U.S. dollars.
Whenever any determination, consent or approval is to be made or given by any Purchaser, such action shall be in such Purchaser’s sole discretion, unless otherwise specified in this Agreement. If any provision in the Basic Documents is held to
be illegal, invalid, not binding or unenforceable, (i) such provision shall be fully severable and the Basic Documents shall be construed and enforced as if such illegal, invalid, not binding or unenforceable provision had never comprised a
part of the Basic Documents, and the remaining 

  
 25 

 
provisions shall remain in full force and effect and (ii) the parties hereto shall negotiate in good faith to modify the Basic Documents so as to effect the original intent of the parties as
closely as possible in an acceptable manner in order that the transactions contemplated hereby are consummated as originally contemplated to the greatest extent possible. When calculating the period of time before which, within which or following
which any act is to be done or step taken pursuant to the Basic Documents, the date that is the reference date in calculating such period shall be excluded. If the last day of such period is a non-Business
Day, the period in question shall end on the next succeeding Business Day. Any words imparting the singular number only shall include the plural and vice versa. The words such as “herein,” “hereinafter,” “hereof” and
“hereunder” refer to this Agreement as a whole and not merely to a subdivision in which such words appear unless the context otherwise requires. The provision of a Table of Contents, the division of this Agreement into Articles, Sections
and other subdivisions and the insertion of headings are for convenience of reference only and shall not affect or be utilized in construing or interpreting this Agreement. 

Section 7.03 Survival of Provisions. The representations and warranties set forth in Sections 3.01,
3.02, 3.03, 3.05, 3.06, 3.30, 4.02, 4.04 and 4.05 hereunder shall survive the execution and delivery of this Agreement for a period of one (1) year, and the other representations and
warranties set forth herein shall survive for a period of six (6) months following the final Closing Date regardless of any investigation made by or on behalf of Contango or a Purchaser. The covenants made in this Agreement shall survive the
final Closing and remain operative and in full force and effect regardless of acceptance of any of the Purchased Securities and payment therefor and repayment, conversion or repurchase thereof. Regardless of any purported general termination of this
Agreement, the provisions of Article V and all indemnification rights and obligations of Contango and the Purchasers thereunder, Section 6.02 and this Article VII shall remain operative and in full force and
effect as between Contango and each Purchaser, unless Contango and each Purchaser execute a writing that expressly (with specific references to the applicable Section or subsection of this Agreement) terminates such rights and obligations as between
Contango and such Purchaser. 
 Section 7.04 No Waiver; Modifications in Writing. 

(a) Delay. No failure or delay on the part of any party in exercising any right, power or remedy hereunder shall operate
as a waiver thereof, nor shall any single or partial exercise of any such right, power or remedy preclude any other or further exercise thereof or the exercise of any other right, power or remedy. The remedies provided for herein are cumulative and
are not exclusive of any remedies that may be available to a party at law or in equity or otherwise. 
 (b) Specific
Waiver. Except as otherwise provided herein, no amendment, waiver, consent, modification or termination of any provision of this Agreement or any other Basic Document shall be effective unless signed by each of the parties hereto or thereto
affected by such amendment, waiver, consent, modification or termination. Any amendment, supplement or modification of or to any provision of this Agreement or any other Basic Document, any waiver of any provision of this Agreement or any other
Basic Document and any consent to any departure by Contango from the terms of any provision of this Agreement or any other Basic Document shall 

  
 26 

 
be effective only in the specific instance and for the specific purpose for which made or given. Except where notice is specifically required by this Agreement, no notice to or demand on Contango
in any case shall entitle Contango to any other or further notice or demand in similar or other circumstances. Any investigation by or on behalf of any party shall not be deemed to constitute a waiver by the party taking such action of compliance
with any representation, warranty, covenant or agreement contained herein. 
 Section 7.05 Binding Effect;
Assignment. 
 (a) Binding Effect. This Agreement shall be binding upon Contango, each Purchaser and their
respective successors and permitted assigns. Except as expressly provided in this Agreement, this Agreement shall not be construed so as to confer any right or benefit upon any Person other than the parties to this Agreement and their respective
successors and permitted assigns; provided that, the representations and warranties of Contango in Article III and the representations and warranties of the Purchasers in Article IV may be relied upon by the Placement Agents, in their
capacity as placement agents for the offering and sale of the Purchased Securities, as third party beneficiaries thereof. 

(b) Assignment of Rights. Without the written consent of Contango, no portion of the rights and obligations of any
Purchaser under this Agreement may be assigned or transferred by such Purchaser. No portion of the rights and obligations of Contango under this Agreement may be transferred or assigned without the prior written consent of the Purchasers. 

Section 7.06 Communications. All notices and demands provided for hereunder shall be (i) in writing and shall

party relating to the foregoing shall be brought in any federal or state court of competent jurisdiction located within the State of Texas, and the parties hereto hereby irrevocably submit to the non-exclusive
jurisdiction of any federal or state court located within the State of Texas over any such action. The parties hereby irrevocably waive, to the fullest extent permitted by applicable Law, any objection which they may now or hereafter have to the
laying of venue of any such dispute brought in such court or any defense of inconvenient forum for the maintenance of such dispute. Each of the parties hereto agrees that a judgment in any such dispute may be enforced in other jurisdictions by suit
on the judgment or in any other manner provided by Law. 
 Section 7.09 Waiver of Jury Trial. EACH OF THE
PARTIES TO THIS AGREEMENT EACH HEREBY WAIVES, AND AGREES TO CAUSE ITS AFFILIATES TO WAIVE, TO THE FULLEST EXTENT PERMITTED BY LAW, ANY RIGHT TO TRIAL BY JURY OF ANY CLAIM, DEMAND, ACTION OR CAUSE OF ACTION (i) ARISING UNDER THIS AGREEMENT OR
(ii) IN ANY WAY CONNECTED WITH OR RELATED OR INCIDENTAL TO THE DEALINGS OF THE PARTIES HERETO IN RESPECT OF THIS AGREEMENT OR ANY OF THE TRANSACTIONS RELATED HERETO, IN EACH CASE WHETHER NOW EXISTING OR HEREAFTER ARISING, AND WHETHER IN

 28 

 
AND CONSENTS THAT ANY SUCH CLAIM, DEMAND, ACTION OR CAUSE OF ACTION SHALL BE DECIDED BY COURT TRIAL WITHOUT A JURY AND THAT THE PARTIES TO THIS AGREEMENT MAY FILE AN ORIGINAL COUNTERPART OF A

Contango agrees that, provided that each Purchaser delivers to Contango a properly executed IRS Form W-9, or similar form sufficient to cause under current Law Contango (including any paying agent of Contango)

 ARTICLE II 

REGISTRATION RIGHTS 

Section 2.1 Shelf Registration. 

(a) Shelf Registration. Contango shall use its commercially reasonable efforts to prepare and file an initial Shelf
Registration Statement under the Securities Act covering all Registrable Securities at such time of filing within 30 days from the date on which the Purchased Securities are issued (the “Filing Deadline”). Contango shall use its
commercially reasonable efforts to cause such initial Shelf Registration Statement to become effective on or as soon as practicable after the filing thereof and no later than 90 days (or if reviewed by the staff of the Commission, 120 days) from the
date on which the Purchased Securities are issued (the “Effectiveness Deadline”). Contango will use its commercially reasonable efforts to cause such initial Shelf Registration Statement filed pursuant to this
Section 2.1(a) to be continuously effective under the Securities Act until the earliest of (1) all Registrable Securities covered by the Shelf Registration Statement have been distributed in the manner set forth and as
contemplated in such Shelf Registration Statement, (2) there are no longer any Registrable Securities outstanding and (3) three years from the Effective Date (the “Effectiveness Period”). A Shelf Registration Statement
filed pursuant to this Section 2.1(a) shall be on such appropriate registration form of the Commission as shall be selected by Contango. A Shelf Registration Statement when declared effective (including the documents
incorporated therein by reference) will comply as to form in all material respects with all applicable requirements of the Securities Act and the Exchange Act and will not contain an untrue statement of a material fact or omit to state a material
fact required to be stated therein or necessary to make the statements therein not misleading (in the case of any prospectus contained in such Shelf Registration Statement, in the light of the circumstances under which a statement is made). As soon
as practicable following the date that a Shelf Registration Statement becomes effective, but in any event within one Business Day of such date, Contango shall provide the Holders with written notice of the effectiveness of a Shelf Registration
Statement. 

  
 4 

 (b) Notwithstanding Contango’s registration obligations set forth in
Section 2.1(a), if the Commission does not permit, as a result of the application of Rule 415, all of the Registrable Securities (after giving effect to all Resale Opt-Out Notices) to
be registered for resale as a secondary offering on a single registration statement, Contango shall use its commercially reasonable efforts to file amendments to the initial Shelf Registration Statement as required by the Commission, covering the
maximum number of Registrable Securities, applied on a pro rata basis among the Holders, permitted by the Commission to be registered on such Shelf Registration Statement. In the event Contango amends the initial Shelf Registration Statement in
accordance with the foregoing, Contango shall use its commercially reasonable efforts to file with the Commission, as promptly as allowed by Commission, one or more Shelf Registration Statements covering those Registrable Securities that were not
registered for resale on the initial Shelf Registration Statement, as amended. 
 (c) Resale Registration Opt-Out. At least three Business Days before the initial filing of the Shelf Registration Statement required by Section 2.1(a), Contango shall provide advance written notice to each
Holder that it plans to file a Shelf Registration Statement. Any Holder may deliver advance written notice (a “Resale Opt-Out Notice”) to Contango requesting that such Holder not be included
in a Shelf Registration Statement prior to its initial filing. Following receipt of a Resale Opt-Out Notice from a Holder, Contango shall not be required to include the Registrable Securities of such Holder in
such Shelf Registration Statement. 
 (d) Delay Rights. Notwithstanding anything to the contrary contained herein,
Contango may, upon written notice to any Selling Holder whose Registrable Securities are included in the Shelf Registration Statement, suspend such Selling Holder’s use of any prospectus which is a part of the Shelf Registration Statement (in
which event the Selling Holder shall discontinue sales of the Registrable Securities pursuant to the Shelf Registration Statement) if (i) Contango is pursuing an acquisition, merger, reorganization, disposition or other similar transaction and
Contango determines in good faith that Contango’s ability to pursue or consummate such a transaction would be materially and adversely affected by any required disclosure of such transaction in the Shelf Registration Statement or
(ii) Contango has experienced some other material non-public event the disclosure of which at such time, in the good faith judgment of Contango, would materially and adversely affect Contango;
provided, however, that in no event shall the Selling Holders be suspended from selling Registrable Securities pursuant to the Shelf Registration Statement for a period of 45 consecutive days or an aggregate of 120 days in any 365-day period. Upon disclosure of such information or the termination of the condition described above, Contango shall provide prompt notice (which notice shall not contain any material, non-public information regarding Contango), to the Selling Holders whose Registrable Securities are included in the Shelf Registration Statement, and shall promptly terminate any suspension of sales it has put into
effect and shall take such other actions necessary or appropriate to permit registered sales of Registrable Securities as contemplated in this Agreement. 

(e) Failure to Obtain and Maintain Effectiveness; Liquidated Damages. If (i) Contango (A) has not filed the initial
Shelf Registration Statement with the Commission on or prior to the Filing Deadline or (B) the initial Shelf Registration Statement is not declared effective by the Commission on or prior to the Effectiveness Deadline (in each case, other than
due to the inaccuracy or omission of any information relating to any Holder provided in writing or required to be provided by or on behalf of a Holder to Contango for inclusion in such Shelf Registration

  
 5 

 
Statement), (ii) during the Effectiveness Period, the Shelf Registration Statement ceases to be effective or the Holders are otherwise not permitted to resell Registrable Securities pursuant to
the Shelf Registration Statement other than (A) for such periods as permitted under Section 2.1(d) of this Agreement or (B) due to the inaccuracy or omission of any information relating to any Holder provided in writing or required to
be provided by or on behalf of a Holder to Contango for inclusion in the Shelf Registration Statement, or (iii) Contango fails to satisfy the current public information requirement pursuant to Rule 144(c)(1) as a result of which the Holders are
unable to sell Registrable Securities without restriction under Rule 144 (any such failure or breach, an “Event” and the date of any Event, an “Event Date”), then each Holder shall be entitled to a payment, as
liquidated damages and not as a penalty, of 0.25% of such Holder’s Liquidated Damages Base per 30-day period, which amount shall accrue daily, for the first 30 days following the applicable Event Date,
increasing by an additional 0.25% of such Holder’s Liquidated Damages Base per 30-day period, that shall accrue daily, for each subsequent 30 days, up to a maximum of 1.00% of the Holder’s Liquidated
Damages Base per 30-day period (the “Liquidated Damages”); provided, however, that no Liquidated Damages shall accrue or be payable if an Event described in clause (i)(B) above
occurred as a result of a review and comments by the staff of the Commission of the Shelf Registration Statement or the documents incorporated by reference therein and Contango uses its commercially reasonable efforts to resolve such comments and
have such Shelf Registration Statement declared effective within 270 days of the filing date of such Shelf Registration Statement. The Liquidated Damages payable pursuant to the immediately preceding sentence shall be payable within 10 Business Days
after the end of each such 30-day period. Notwithstanding anything to the contrary contained herein, in no event shall the aggregate of all Liquidated Damages payable by Contango under this
Section 2.1(e) exceed 5.00% of such Holder’s Liquidated Damages Base. Liquidated Damages payable to a Holder shall cease to accrue when the Event is cured or the Holder no longer owns Registrable Securities, whichever
is earlier, and shall be prorated in the event Liquidated Damages cease to accrue prior to the end of the applicable 30-day calculation period. 

Section 2.2 Piggyback Registration Participation. If at any time Contango proposes to file (i) at a time when
Contango is not a WKSI, a registration statement and such Holder has not previously included its Registrable Securities in a Shelf Registration Statement contemplated by Section 2.1(a) of this Agreement that is currently
effective, or (ii) a prospectus supplement to an effective “automatic shelf registration statement” (as defined in Rule 405 under the Securities Act), so long as Contango is a WKSI at such time or, whether or not Contango is a WKSI,
so long as the Registrable Securities were previously included in the underlying Shelf Registration Statement, or in any case in which Holders may participate in such offering without the filing of a post-effective amendment, in each case, for the
sale of Common Stock in an Underwritten Offering for its own account and/or another Person, other than (a) a registration relating solely to employee benefit plans, (b) a registration relating solely to a Rule 145 transaction, or
(c) a registration statement on any registration form which does not permit secondary sales, then Contango shall give not less than three Business Days advance notice (including, but not limited to, notification by e-mail; such notice, a “Piggyback Notice”) of such proposed Underwritten Offering to each Holder that, together with its Affiliates, owns more than $2.5 million of Registrable Securities, and
such notice shall offer such Holder the opportunity to participate in any Underwritten Offering and to include in such Underwritten Offering such number of Registrable Securities (the “Included Registrable Securities”) as each such
Holder may request in writing (a “Piggyback Registration”); provided, however, that Contango (A) shall not be required to include the Registrable Securities 

  
 6 

 
of the Holders in such Registration if the Holders do not offer a minimum of $2.5 million of Registrable Securities, or (B) if Contango has been advised by the Managing Underwriter that
the inclusion of Registrable Securities for sale for the benefit of the Holders will have material and adverse effect on the offering price, timing or probability of success of the distribution of the Common Stock in the Underwritten Offering, then
the amount of Registrable Securities to be offered for the accounts of Holders shall be determined based on the provisions of Section 2.2(b). If Contango is not required to offer the opportunity for a Piggyback Registration
in respect of a proposed Underwritten Offering as a result of the circumstance described in clause (B) of the proviso of the immediately preceding sentence, then Contango shall nevertheless be required to furnish to such Holders the Piggyback
Notice in respect of such proposed Underwritten Offering, which notice shall describe Contango’s intention to conduct an Underwritten Offering and, if the determination described in clause (B) of the proviso of the immediately preceding
sentence has been made at the time that the Piggyback Notice is required to be given by Contango, shall include notification that the Holders do not have the opportunity to include Registrable Securities in such Underwritten Offering because
Contango has been advised by the Managing Underwriter that the inclusion of Registrable Securities for sale for the benefit of the Holders will have a material and adverse effect on the offering price, timing or probability of success of the
distribution of the Common Stock in the Underwritten Offering. If the circumstance described in clause (B) of the proviso of the preceding sentence is made after the Piggyback Notice has been given, then Contango shall notify the Holders who
were provided such Piggyback Notice (or if the two Business Day period referred to in the next sentence has lapsed, the Holders who have timely elected to include Registrable Securities in such offering) in writing of such circumstance and the
aggregate number of Registrable Securities, if any, that can be included in such offering. Each Piggyback Notice shall be provided to Holders on a Business Day pursuant to Section 3.1 hereof and confirmation of receipt of
such notice shall be requested in the notice. The Holder will have two Business Days after notice has been delivered to request in writing the inclusion of Registrable Securities in the Underwritten Offering. If no request for inclusion from a
Holder is received within the specified time, such Holder shall have no further right to participate in such Piggyback Registration. If, at any time after giving written notice of its intention to undertake an Underwritten Offering and prior to the
closing of such Underwritten Offering, Contango shall determine for any reason not to undertake or to delay such Underwritten Offering, Contango may, at its election, give written notice of such determination to the Selling Holders and, (x) in
the case of a determination not to undertake such Underwritten Offering, shall be relieved of its obligation to sell any Included Registrable Securities in connection with such terminated Underwritten Offering, and (y) in the case of a
determination to delay such Underwritten Offering, shall be permitted to delay offering any Included Registrable Securities for the same period as the delay in the Underwritten Offering. Any Selling Holder shall have the right to withdraw such
Selling Holder’s request for inclusion of such Selling Holder’s Registrable Securities in such Underwritten Offering by giving written notice to Contango of such withdrawal up to and including the time of pricing of such offering. Any
Holder may deliver written notice (a “Piggyback Opt-Out Notice”) to Contango requesting that such Holder not receive notice from Contango of any proposed Underwritten Offering; provided,
however, that such Holder may later revoke any such Piggyback Opt-Out Notice in writing. Following receipt of a Piggyback Opt-Out Notice from a Holder (unless
subsequently revoked), Contango shall not be required to deliver any notice to such Holder pursuant to this Section 2.2(a) and such Holder shall no longer be entitled to participate in Underwritten Offerings by Contango
pursuant to this Section 2.2(a), unless such Piggyback Opt-Out Notice is revoked by such Holder. 

  
 7 

 (b) Priority of Piggyback Registration. If the Managing Underwriter
or Underwriters of any proposed Underwritten Offering of shares of Common Stock included in a Piggyback Registration advises Contango that the total shares of Common Stock which the Selling Holders and any other Persons intend to include in such
offering exceeds the number which can be sold in such offering without being likely to have a material and adverse effect on the offering price, timing or probability of success of the distribution of the Common Stock offered or the market for the
Common Stock, then the Piggyback Notice provided by Contango pursuant to Section 2.2(a) shall include notification of such determination or, if such determination is made after the Piggyback Notice has been given, then
Contango shall furnish notice in writing (including by e-mail) to the Holders (or to those who have timely elected to participate in such Underwritten Offering), and the Common Stock to be included in such
Underwritten Offering shall include the number of shares of Common Stock that such Managing Underwriter or Underwriters advises Contango can be sold without having such material and adverse effect, with such number to be allocated (i) if such
Piggyback Registration was initiated by Contango, (A) first, to Contango, (B) second, pro rata among the Selling Holders and any other Persons who have been or after the date hereof are granted registration rights on parity with the
registration rights granted under this Agreement (the “Other Holders”) who have requested participation in the Piggyback Registration (based, for each such Selling Holder or Other Holder, on the percentage derived by dividing
(1) the number of shares of Common Stock proposed to be sold by such Selling Holder or such Other Holder in such offering; by (2) the aggregate number of shares of Common Stock proposed to be sold by all Selling Holders and all Other
Holders in the Piggyback Registration), and (C) third, to any other holder of shares of common stock with registration rights that are subordinate to the rights of the Holders hereunder and (ii) if such Piggyback Registration was not
initiated by Contango, (A) first, to the Persons initiating such Registration, (B) second, pro rata among the Selling Holders and any Other Holders who have requested participation in the Piggyback Registration (based, for each such
Selling Holder or Other Holder, on the percentage derived by dividing (1) the number of shares of Common Stock proposed to be sold by such Selling Holder or such Other Holder in such offering; by (2) the aggregate number of shares of
Common Stock proposed to be sold by all Selling Holders and all Other Holders in the Piggyback Registration other than the Persons initiating such Registration), and (C) third, to any other holder of shares of common stock with registration
rights that are subordinate to the rights of the Holders hereunder. 
 Section 2.3 Secondary Underwritten
Offering. 
 (a) S-3 Registration. In the event that a Selling Holder or a
group of Selling Holders elects to dispose of Registrable Securities under the Shelf Registration Statement pursuant to an Underwritten Offering for its own account of at least $5.0 million (such amount, the “Minimum
Commitment”), such Selling Holder shall give notice of such election in writing (including, but not limited to, notification by e-mail; such notice, the “Selling Holder Election
Notice”) to Contango not less than 20 Business Days before the date such Selling Holder intends for such Underwritten Offering to commence marketing (whether on a confidential basis or on a public basis); provided that Contango shall
not be required to conduct more than one Underwritten Offering pursuant to this Section 2.3 in any 180-day period pursuant to Selling Holder Election Notices. The Selling Holder
Election Notice shall specify the number of Registrable Securities 

  
 8 

 
that the Selling Holder intends to offer in such Underwritten Offering and the expected commencement date thereof. Contango shall, at the request of such Selling Holder, enter into an
underwriting agreement in customary form with the Managing Underwriter or Underwriters, which shall include, among other provisions, indemnities to the effect and to the extent provided in Section 2.8, and shall take all
such other reasonable actions as are requested by the Managing Underwriter in order to expedite or facilitate the disposition of the Registrable Securities. 

(b) Notice to Holders. Not later than two Business Days after receipt by Contango of the Selling Holder Election Notice,
unless Contango determines in accordance with Section 2.1(d) to delay such Underwritten Offering (in which event Contango shall promptly notify the initiating Selling Holder in writing of such determination), then Contango
shall provide written notice (including, but not limited to, notification by e-mail) to the other Holders of Registrable Securities of the Selling Holder’s intention to conduct an Underwritten Offering
and such notice shall offer such other Holders the opportunity to participate in such Underwritten Offering and to include in such Underwritten Offering such number of Registrable Securities as each such Holder may request in writing. Each such
other Holder will have five Business Days after notice has been delivered to request in writing submitted to Contango the inclusion of Registrable Securities in the Underwritten Offering. If no request for inclusion from a Holder is received by
Contango within the specified time, such Holder shall have no further right to participate in such Underwritten Offering. If, at any time after giving written notice of its intention to undertake an Underwritten Offering and prior to the closing of
such Underwritten Offering, the Selling Holder giving the notice shall determine for any reason not to undertake or to delay such Underwritten Offering, such Selling Holder may, at its election, give written notice of such determination to Contango
and, if the failure of such Selling Holder to participate would cause the aggregate amount of Registrable Securities participating in the Underwritten Offering to fall below the Minimum Commitment, Contango shall notify the other Holders and,
(x) in the case of a determination not to undertake such Underwritten Offering, shall be relieved of its obligation to include Registrable Securities of any other Holder, and (y) in the case of a determination to delay such Underwritten
Offering, shall be permitted to delay offering any Registrable Securities of any other Holder for the same period as the delay in the Underwritten Offering. Any other Holder shall have the right to withdraw such Holder’s request for inclusion
of such Holder’s Registrable Securities in such Underwritten Offering by giving written notice to Contango of such withdrawal up to and including the time of pricing of such offering. If the Managing Underwriter or Underwriters of any proposed
Underwritten Offering of Registrable Securities under a Shelf Registration Statement advises Contango that the total amount of Registrable Securities which the Selling Holders and any other Persons intend to include in such offering exceeds the
number which can be sold in such offering without being likely to have a material and adverse effect on the offering price, timing or probability of success of the distribution of the Registrable Securities offered or the market for the Registrable
Securities, then the Registrable Securities to be included in such Underwritten Offering shall include the number of Registrable Securities that such Managing Underwriter or Underwriters advises Contango can be sold without having such material and
adverse effect, with such number to be allocated pro rata among the Selling Holders and the other Holders who have requested participation in the Underwritten Offering (based, for each such Selling Holder or other Holder, on the percentage derived
by dividing (A) the number of Registrable Securities proposed to be sold by such Selling Holder or such other Holder in such offering; by (B) the aggregate number of Registrable Securities proposed to be sold by all Selling Holders and all
other Holders in such Underwritten Offering).

 Section 2.4 Sale Procedures. 

(a) General Procedures. In connection with any Underwritten Offering (i) under
Section 2.2 of this Agreement, Contango shall be entitled to select the Managing Underwriter or Underwriters, and (ii) under Section 2.3 of this Agreement, the Selling Holders shall be
entitled to select the Managing Underwriter or Underwriters. In connection with an Underwritten Offering contemplated by this Agreement in which a Selling Holder participates, each Selling Holder and Contango shall be obligated to enter into an
underwriting agreement with the Managing Underwriter or Underwriters which contains such representations, covenants, indemnities and other rights and obligations as are customary in underwriting agreements for firm commitment offerings of equity
securities. No Selling Holder may participate in such Underwritten Offering unless such Selling Holder agrees to sell its Registrable Securities on the basis provided in such underwriting agreement and completes and executes all questionnaires,
powers of attorney, indemnities and other documents reasonably required under the terms of such underwriting agreement. Each Selling Holder may, at its option, require that any or all of the representations and warranties by, and the other
agreements on the part of, Contango to and for the benefit of such underwriters also be made to and for such Selling Holder’s benefit and that any or all of the conditions precedent to the obligations of such underwriters under such
underwriting agreement also be conditions precedent to its obligations. No Selling Holder shall be required to make any representations or warranties to or agreements with Contango or the underwriters other than representations, warranties or
agreements regarding such Selling Holder’s ownership of the securities being registered on its behalf and its intended method of distribution and any other representation required by law. If any Selling Holder disapproves of the terms of an
underwriting, such Selling Holder may elect to withdraw therefrom by notice to Contango and the Managing Underwriter; provided, however, that such withdrawal must be made at least one Business Day prior to the time of pricing of such
Underwritten Offering to be effective. No such withdrawal or abandonment shall affect Contango’s obligation to pay Registration Expenses. Upon the receipt by Contango of a written request from the Holders of at least $5.0 million dollars
of Registrable Securities that are participating in any Underwritten Offering contemplated by this Agreement, Contango’s management shall be required to participate in a roadshow or similar marketing effort in connection with any Underwritten
Offering. 
 (b) In connection with its obligations under this Article II, Contango will, as expeditiously as
possible: 
 (i) prepare and file with the Commission such amendments and supplements to the Shelf
Registration Statement and the prospectus used in connection therewith as may be necessary to keep a Shelf Registration Statement effective for the Effectiveness Period and as may be necessary to comply with the provisions of the Securities Act with
respect to the disposition of all Registrable Securities covered by a Shelf Registration Statement; 
 (ii)
if a prospectus supplement will be used in connection with the marketing of an Underwritten Offering from a Shelf Registration Statement and the Managing Underwriter at any time shall notify Contango in writing that, in the sole judgment of such
Managing Underwriter, the inclusion of detailed information to be used in such prospectus supplement is of material importance to the success of the Underwritten Offering of such Registrable Securities, Contango shall use its commercially reasonable
efforts to include such information in the prospectus supplement; 

  
 10 

 (iii) furnish to each Selling Holder (A) as far in
advance as reasonably practicable before filing a Shelf Registration Statement or any other registration statement contemplated by this Agreement or any supplement or amendment thereto, upon request, copies of reasonably complete drafts of all such
documents proposed to be filed (including exhibits and each document incorporated by reference therein to the extent then required by the rules and regulations of the Commission), and provide each such Selling Holder the opportunity to object to any
information pertaining to such Selling Holder and its plan of distribution that is contained therein and make the corrections reasonably requested by such Selling Holder with respect to such information prior to filing such Shelf Registration
Statement or such other registration statement and the prospectus included therein or any supplement or amendment thereto, and (B) such number of copies of such Shelf Registration Statement or such other registration statement and the
prospectus included therein and any supplements and amendments thereto as such Persons may reasonably request in order to facilitate the public sale or other disposition of the Registrable Securities covered by such Shelf Registration Statement or
other registration statement; 
 (iv) if applicable, use its commercially reasonable efforts to register or
qualify the Registrable Securities covered by a Shelf Registration Statement or any other registration statement contemplated by this Agreement under the securities or blue sky laws of such jurisdictions as the Selling Holders shall reasonably
request, provided that Contango will not be required to qualify generally to transact business in any jurisdiction where it is not then required to so qualify or to take any action which would subject it to general service of process in any such
jurisdiction where it is not then so subject; 
 (v) promptly notify each Selling Holder, at any time when a
prospectus relating thereto is required to be delivered under the Securities Act, of (A) the filing of a Shelf Registration Statement or any other registration statement contemplated by this Agreement or any prospectus included therein or any
amendment or supplement thereto (other than any amendment or supplement resulting from the filing of a document incorporated by reference therein), and, with respect to such Shelf Registration Statement or any other registration statement or any
post-effective amendment thereto, when the same has become effective; and (B) the receipt of any written comments from the Commission with respect to any filing referred to in clause (A) and any written request by the Commission for
amendments or supplements to such Shelf Registration Statement or any other registration statement or any prospectus or prospectus supplement thereto; 

(vi) immediately notify each Selling Holder, at any time when a prospectus relating thereto is required to be
delivered under the Securities Act, of (A) the happening of any event as a result of which the prospectus contained in a Shelf Registration Statement or any other registration statement contemplated by this Agreement or any supplemental
amendment thereto, includes an untrue statement of a material fact or omits to state any material fact required to be stated therein or necessary to make the statements therein not misleading in the light of the circumstances then existing;
(B) the issuance or threat of issuance by the Commission of any stop order suspending the effectiveness of

any notification with respect to the suspension of the qualification of any Registrable Securities for sale under the applicable securities or blue sky laws of any jurisdiction. Following the provision of such notice, Contango agrees to as promptly
as practicable amend or supplement the prospectus or prospectus supplement or take other appropriate action so that the prospectus or prospectus supplement does not include an untrue statement of a material fact or omit to state a material fact
required to be stated therein or necessary to make the statements therein not misleading in the light of the circumstances then existing and to take such other action as is necessary to remove a stop order, suspension, threat thereof or proceedings
related thereto; 
 (vii) upon request and subject to appropriate confidentiality obligations, furnish to
each Selling Holder copies of any and all transmittal letters or other correspondence with the Commission or any other governmental agency or self-regulatory body or other body having jurisdiction (including any domestic or foreign securities
exchange) relating to such offering of Registrable Securities; 
 (viii) in the case of an Underwritten
Offering, furnish upon request a “comfort” letter, dated the pricing date of such Underwritten Offering and a letter of like kind dated the date of the closing under the underwriting agreement, in each case, signed by the independent
public accountants who have certified Contango’s financial statements included or incorporated by reference into the applicable registration statement, and the “comfort” letter shall be in customary form and covering substantially the
same matters with respect to such registration statement (and the prospectus included therein and any supplement thereto) and as are customarily covered in accountants’ letters delivered to the underwriters in underwritten offerings of
securities; 
 (ix) in the case of an Underwritten Offering, use commercially reasonable efforts to furnish
upon request a letter, dated the pricing date of such Underwritten Offering and a letter of like kind dated the date of the closing under the underwriting agreement, in each case, signed by the reserve engineers who have prepared reserve reports of
estimated net proved oil and natural gas reserves with respect to certain oil and gas properties included or incorporated by reference into the applicable registration statement, and the letter shall be in customary form and covering substantially
the same matters with respect to such registration statement (and the prospectus included therein and any supplement thereto) and as are customarily covered in reserve engineers’ letters delivered to the underwriters in underwritten offerings
of securities; 
 (x) in the case of an Underwritten Offering, use commercially reasonable efforts to furnish
upon request an opinion of counsel to Contango, dated the date of the closing under the underwriting agreement, in form and substance satisfactory to the underwriters of such Underwritten Offering; 

(xi) otherwise use its commercially reasonable efforts to comply with all applicable rules and regulations of
the Commission and make available to its security holders, as soon as reasonably practicable, an earnings statement covering the period of at least 12 months, but not more than 18 months, beginning with the first full calendar month after
the effective date of such registration statement, which earnings statement shall satisfy the provisions of Section 11(a) of the Securities Act and Rule 158 promulgated thereunder; 

  
 12 

 (xii) make available to the appropriate representatives of
the underwriters access to such information and Contango personnel as is reasonable and customary to enable such parties and their representatives to establish a due diligence defense under the Securities Act; provided that Contango need not
disclose any non-public information to any such representatives unless and until such representatives have entered into a confidentiality agreement with Contango; 

(xiii) cause all such Registrable Securities registered pursuant to this Agreement to be listed or quoted on
each securities exchange or nationally recognized quotation system on which similar securities issued by Contango are then listed or quoted, and cause to be satisfied all requirements and conditions of such securities exchange or nationally
recognized quotation system to the listing or quoting of such Registrable Securities that are reasonably within the control of Contango, including, without limitation, registering the Registrable Securities under the Exchange Act, if appropriate,
and using commercially reasonable efforts to cause such registration to become effective pursuant to the rule of the Commission; 

(xiv) use its commercially reasonable efforts to cause the Registrable Securities to be registered with or
approved by such other governmental agencies or authorities as may be necessary by virtue of the business and operations of Contango to enable the Selling Holders to consummate the disposition of such Registrable Securities; 

(xv) provide a transfer agent and registrar for all Registrable Securities covered by such registration
statement; and 
 (xvi) enter into customary agreements and take such other actions as are reasonably
requested by the Selling Holders in order to expedite or facilitate the disposition of such Registrable Securities. 
 (c)
Each Selling Holder, upon receipt of notice from Contango of the happening of any event of the kind described in Section 2.4(b)(vi), shall forthwith discontinue disposition of the Registrable Securities until such Selling
Holder’s receipt of the copies of the supplemented or amended prospectus contemplated by Section 2.4(b)(vi) or until it is advised in writing by Contango that the use of the prospectus may be resumed, and has received
copies of any additional or supplemental filings incorporated by reference in the prospectus, and, if so directed by Contango, such Selling Holder will, or will request the Managing Underwriter or underwriters, if any, to deliver to Contango (at
Contango’s expense) all copies in their possession or control, other than permanent file copies then in such Selling Holder’s possession, of the prospectus and any prospectus supplement covering such Registrable Securities current at the
time of receipt of such notice. 

  
 13 

 Section 2.5 Cooperation by Holders. Contango shall have no
obligation to include Registrable Securities of a Holder in the Shelf Registration Statement or in an Underwritten Offering under Article II of this Agreement if such Selling Holder has failed to timely furnish such information which, after
consultation with its counsel, is reasonably required in order for the registration statement or prospectus supplement, as applicable, to comply with the Securities Act. 

Section 2.6 [Reserved]. 

Section 2.7 Expenses. 

(a) Certain Definitions. “Registration Expenses” means all expenses incident to Contango’s
performance under or compliance with this Agreement to effect the registration of Registrable Securities in a Shelf Registration Statement pursuant to Section 2.1, a Piggyback Registration pursuant to
Section 2.2, or an Underwritten Offering pursuant to Section 2.3 and the disposition of such securities, including, without limitation, all registration, filing, securities exchange listing and
fees, all registration, filing, qualification and other fees and expenses of complying with securities or blue sky laws, fees of the Financial Industry Regulatory Authority, transfer taxes and fees of transfer agents and registrars, all word
processing, duplicating and printing expenses, all roadshow expenses borne by it and the fees and disbursements of independent public accountants and counsel for Contango, including the expenses of any special audits or “comfort” letters
required by or incident to such performance and compliance. Except as otherwise provided in Section 2.8 hereof, Contango shall not be responsible for legal fees incurred by Holders in connection with the exercise of such
Holders’ rights hereunder. In addition, Contango shall not be responsible for any “Selling Expenses,” which means all underwriting fees, discounts and selling commissions and transfer taxes allocable to the sale of the
Registrable Securities. 
 (b) Expenses. Contango will pay all reasonable Registration Expenses in connection with a
Shelf Registration Statement, Piggyback Registration or Underwritten Offering, whether or not any sale is made pursuant to such Shelf Registration Statement, Piggyback Registration or Underwritten Offering. Each Selling Holder shall pay its pro rata
share of all Selling Expenses in connection with any sale of its Registrable Securities hereunder. 
 Section 2.8
Indemnification. 
 (a) By Contango. In the event of a registration of any Registrable Securities under the
Securities Act pursuant to this Agreement, to the extent permitted by applicable law, Contango will indemnify and hold harmless each Selling Holder thereunder, its directors, officers, partners, members, employees, investment advisers, agents,
representatives and managers, and each other Person, if any, who controls such Selling Holder, within the meaning of the Securities Act and the Exchange Act, and the directors, officers, partners, members, employees, investment advisers, agents,
representatives and managers of such controlling Person, against any losses, claims, damages, expenses or liabilities (including reasonable attorneys’ fees and expenses), including any of the foregoing incurred in settlement of any litigation
commenced or threatened by any party other than a Selling Holder (collectively, “Losses”), joint or several, to which such Selling Holder or controlling Person or directors, officers, employees, agents, representatives or managers
may become subject under the Securities Act, the Exchange Act or otherwise, insofar as such Losses (or actions or proceedings, whether commenced or threatened, in respect thereof) arise out of or are based upon any untrue statement or alleged untrue
statement of any material fact (in 

  
 14 

 
the case of any prospectus, in light of the circumstances under which such statement is made) contained in the Shelf Registration Statement or any other registration statement contemplated by
this Agreement, any preliminary prospectus or final prospectus contained therein, or any free writing prospectus related thereto, or any amendment or supplement thereof, or arise out of or are based upon the omission or alleged omission to state
therein a material fact required to be stated therein or necessary to make the statements therein (in the case of a prospectus, in light of the circumstances under which they were made) not misleading, and will reimburse each such Selling Holder,
its directors and officers, and each such controlling Person and each such director, officer, employee, agent, representatives or manager for any legal or other expenses reasonably incurred by them in connection with investigating or defending any
such Loss or actions or proceedings; provided, however, that Contango will not be liable in any such case if and to the extent that any such Loss arises out of or is based upon an untrue statement or alleged untrue statement or
omission or alleged omission so made in conformity with information furnished by such Selling Holder or such controlling Person in writing specifically for use in the Shelf Registration Statement or such other registration statement, or prospectus
supplement, as applicable. Such indemnity shall remain in full force and effect regardless of any investigation made by or on behalf of such Selling Holder or any such director, officer, partner, member, employee, investment adviser, agent,
representatives, manager or controlling Person, and shall survive the transfer of such securities by such Selling Holder. 

(b) By Each Selling Holder. Each Selling Holder agrees severally and not jointly to indemnify and hold harmless
Contango, its directors, officers, employees, representatives and agents and each Person, if any, who controls Contango within the meaning of the Securities Act or of the Exchange Act to the same extent as the foregoing indemnity from Contango to
the Selling Holders, but only with respect to information regarding such Selling Holder furnished in writing by or on behalf of such Selling Holder expressly for inclusion in the Shelf Registration Statement or prospectus supplement relating to the
Registrable Securities, or any amendment or supplement thereto. The maximum liability of each Selling Holder for any such indemnification shall not exceed the amount of net proceeds received by such seller from the sale of such Selling Holder’s
Registrable Securities. 
 (c) Notice. Promptly after receipt by an indemnified party hereunder of notice of the
commencement of any action, such indemnified party shall, if a claim in respect thereof is to be made against the indemnifying party hereunder, notify the indemnifying party in writing thereof, but the omission so to notify the indemnifying party
shall not relieve it from any liability which it may have to any indemnified party other than under this Section 2.8(c) except to the extent that the indemnifying party is materially prejudiced by such failure. In any
action brought against any indemnified party, it shall notify the indemnifying party of the commencement thereof. The indemnifying party shall be entitled to participate in and, to the extent it shall wish, to assume and undertake the defense
thereof with counsel reasonably satisfactory to such indemnified party and, after notice from the indemnifying party to such indemnified party of its election so to assume and undertake the defense thereof, the indemnifying party shall not be liable
to such indemnified party under this Section 2.8 for any legal expenses subsequently incurred by such indemnified party in connection with the defense thereof other than reasonable costs of investigation and of liaison with
counsel so selected; provided, however, that, (i) if the indemnifying party has failed to assume the defense and employ counsel reasonably satisfactory to the indemnified party or (ii) if the defendants in any such action
include both the indemnified party and the indemnifying party and 

  
 15 

 
counsel to the indemnified party shall have concluded that there may be reasonable defenses available to the indemnified party that are different from or additional to those available to the
indemnifying party, or if the interests of the indemnified party reasonably may be deemed to conflict with the interests of the indemnifying party or representation by both parties by the same counsel is otherwise inappropriate under the applicable
standards of professional conduct, then the indemnified party shall have the right to select a separate counsel and to assume such legal defense and otherwise to participate in the defense of such action, with the reasonable expenses and fees of
such separate counsel and other reasonable expenses related to such participation to be reimbursed by the indemnifying party as incurred. Notwithstanding any other provision of this Agreement, the indemnifying party shall not settle any indemnified
claim without the consent of the indemnified party, unless the settlement thereof imposes no liability or obligation on, includes a complete release from liability of, and does not contain any admission of wrong doing by, the indemnified party. 

(d) Contribution. If the indemnification provided for in this Section 2.8 is held by a court
or government agency of competent jurisdiction to be unavailable to Contango or any Selling Holder or is insufficient to hold them harmless in respect of any Losses, then each such indemnifying party, in lieu of indemnifying such indemnified party,
shall contribute to the amount paid or payable by such indemnified party as a result of such Losses in such proportion as is appropriate to reflect the relative fault of Contango on the one hand and of such Selling Holder on the other in connection
with the statements or omissions which resulted in such Losses, as well as any other relevant equitable considerations; provided, however, that in no event shall such Selling Holder be required to contribute an aggregate amount in
excess of the dollar amount of proceeds (net of Selling Expenses) received by such Selling Holder from the sale of Registrable Securities giving rise to such indemnification less the amount of any damages that such Selling Holder has otherwise been
required to pay by reason of such untrue or alleged untrue statement or omission or alleged omission. The relative fault of Contango on the one hand and each Selling Holder on the other shall be determined by reference to, among other things,
whether the untrue or alleged untrue statement of a material fact or the omission or alleged omission to state a material fact has been made by, or relates to, information supplied by such party, and the parties’ relative intent, knowledge,
access to information and opportunity to correct or prevent such statement or omission. The parties hereto agree that it would not be just and equitable if contributions pursuant to this paragraph were to be determined by pro rata allocation or by
any other method of allocation which does not take account of the equitable considerations referred to in the first sentence of this paragraph. The amount paid by an indemnified party as a result of the Losses referred to in the first sentence of
this paragraph shall be deemed to include any legal and other expenses reasonably incurred by such indemnified party in connection with investigating or defending any Loss which is the subject of this paragraph. No person guilty of fraudulent
misrepresentation (within the meaning of Section 11(f) of the Securities Act) shall be entitled to contribution from any Person who is not guilty of such fraudulent misrepresentation. 

(e) Other Indemnification. The provisions of this Section 2.8 shall be in addition to any
other rights to indemnification or contribution which an indemnified party may have pursuant to law, equity, contract or otherwise. 

Section 2.9 Rule 144 Reporting. With a view to making available the benefits of certain rules and regulations of
the Commission that may permit the sale of the Registrable Securities to the public without registration, Contango agrees to use its commercially reasonable efforts to: 

(a) Make and keep public information regarding Contango available, as those terms are understood and defined in Rule 144; 

  
 16 

 (b) File with the Commission in a timely manner all reports and other
documents required of Contango under the Securities Act and the Exchange Act; and 
 (c) So long as a Holder, together with
its Affiliates, owns any Registrable Securities, (i) unless otherwise available at no charge by access electronically to the Commission’s EDGAR filing system (or any successor system), furnish to such Holder forthwith upon request a copy
of the most recent annual or quarterly report of Contango, and such other reports and documents so filed as such Holder may reasonably request in availing itself of any rule or regulation of the Commission allowing such Holder to sell any such
securities without registration and (ii) to the extent accurate, furnish to such Holder upon reasonable request a written statement of Contango that it has complied with the reporting requirements of Rule 144. 

Section 2.10 Transfer or Assignment of Registration Rights. The rights to cause Contango to register Registrable
Securities granted to the Purchasers by Contango under this Article II may be transferred or assigned by any Purchaser to one or more transferees or assignees of Registrable Securities; provided, however, that
(a) unless the transferee or assignee is an Affiliate of, and after such transfer or assignment continues to be an Affiliate of, such Purchaser, the amount of Registrable Securities transferred or assigned to such transferee or assignee shall
represent at least $2.5 million of Registrable Securities (based on the Common Stock Price) or, if less, 100% of the Registrable Securities then held by such Purchaser, (b) Contango is given written notice prior to any said transfer or
assignment, stating the name and address of each such transferee or assignee and identifying the securities with respect to which such registration rights are being transferred or assigned, and (c) each such transferee or assignee assumes in
writing responsibility for its portion of the obligations of such Purchaser under this Agreement. 
 Section 2.11
Aggregation of Registrable Securities. (a) All Registrable Securities held or acquired by Persons who are Affiliates of one another shall be aggregated together for the purpose of determining the availability of any rights under this
Agreement. In addition, all Registrable Securities held or acquired by each T. Rowe Price Holder shall be aggregated together with each other T. Rowe Price Holder for the purpose of determining the availability of any rights under this Agreement.

 (b) All other shares of Common Stock held by a Person and for which such Person has similar registration rights pursuant
to an agreement between such Person and Contango shall be aggregated together for the purpose of determining such Person’s rights under this Agreement solely as such shares relate to minimum quantity requirements contemplated herein; provided
that, for the avoidance of doubt, such Common Stock shall not otherwise be deemed Registrable Securities for any other purpose under this Agreement.

 18 

 Section 3.5 Specific Performance. Damages in the event of breach
of this Agreement by a party hereto would be difficult, if not impossible, to ascertain, and it is therefore agreed that each such Person, in addition to and without limiting any other remedy or right it may have, will have the right to an
injunction or other equitable relief in any court of competent jurisdiction, enjoining any such breach, and enforcing specifically the terms and provisions hereof, and each of the parties hereto hereby waives (a) any and all defenses it may
have on the ground of lack of jurisdiction or competence of the court to grant such an injunction or other equitable relief or that a remedy at law would be adequate and (b) any requirement under any law to post securities as a prerequisite to
obtaining equitable relief. The existence of this right will not preclude any such Person from pursuing any other rights and remedies at law or in equity which such Person may have. 

Section 3.6 Counterparts. This Agreement may be executed in any number of counterparts and by different parties
hereto in separate counterparts, each of which counterparts, when so executed and delivered, shall be deemed to be an original and all of which counterparts, taken together, shall constitute but one and the same Agreement. 

Section 3.7 Headings. The headings in this Agreement are for convenience of reference only and shall not limit or
otherwise affect the meaning hereof.

WAIVE, AND AGREE TO CAUSE THEIR AFFILIATES TO WAIVE, TO THE FULLEST EXTENT PERMITTED BY LAW, ANY RIGHT TO TRIAL BY JURY OF ANY CLAIM, DEMAND, ACTION OR CAUSE OF ACTION (i) ARISING UNDER THIS AGREEMENT OR (ii) IN ANY WAY CONNECTED WITH OR
RELATED OR INCIDENTAL TO THE DEALINGS OF THE PARTIES HERETO IN RESPECT OF THIS AGREEMENT OR ANY OF THE TRANSACTIONS RELATED HERETO, IN EACH CASE WHETHER NOW EXISTING OR HEREAFTER ARISING, AND WHETHER IN CONTRACT, TORT, EQUITY OR OTHERWISE. THE
PARTIES TO THIS AGREEMENT EACH HEREBY AGREES AND CONSENTS THAT ANY SUCH CLAIM, DEMAND, ACTION OR CAUSE OF ACTION SHALL BE DECIDED BY COURT TRIAL WITHOUT A JURY AND THAT THE PARTIES TO THIS AGREEMENT MAY FILE AN ORIGINAL COUNTERPART OF A COPY OF THIS

 19 

 Section 3.10 Severability of Provisions. Any provision of this
Agreement which is prohibited or unenforceable in any jurisdiction shall, as to such jurisdiction, be ineffective to the extent of such prohibition or unenforceability without invalidating the remaining provisions hereof or affecting or impairing
the validity or enforceability of such provision in any other jurisdiction. 
 Section 3.11 Entire Agreement.

matter contained herein or therein. There are no restrictions, promises, warranties or undertakings, other than those set forth or referred to herein or therein with respect to the rights granted by Contango set forth herein or therein. This
Agreement and the Purchase Agreement supersede all prior agreements and understandings between the parties with respect to such subject matter. 

Section 3.12 Term; Amendment. This Agreement shall automatically terminate and be of no further force and effect
on the date on which there are no Registrable Securities. This Agreement may be amended only by means of a written amendment signed by Contango and the Holders of a majority of the then outstanding Registrable Securities; provided,
however, that no such amendment shall materially and adversely affect the rights of any Holder hereunder without the consent of such Holder. 

Section 3.13 No Presumption. In the event any claim is made by a party relating to any conflict, omission, or
ambiguity in this Agreement, no presumption or burden of proof or persuasion shall be implied by virtue of the fact that this Agreement was prepared by or at the request of a particular party or its counsel. 

Section 3.14 Obligations Limited to Parties to Agreement. Each of the parties hereto covenants, agrees and
acknowledges that no Person other than the Purchasers, Selling Holders, their respective permitted assignees and Contango shall have any obligation hereunder and that, notwithstanding that one or more of Contango and the Purchasers may be a
corporation, partnership or limited liability company, no recourse under this Agreement or under any documents or instruments delivered in connection herewith or therewith shall be had against any former, current or future director, officer,
employee, agent, general or limited partner, manager, member, stockholder or Affiliate of any of Contango, the Purchasers, Selling Holders or their respective permitted assignees, or any former, current or future director, officer, employee, agent,

COVENANTS RELATED TO CONTANGO

good standing under the laws of the State of Texas, with full corporate power and authority to own, lease and operate its properties and assets and conduct its business as described in the SEC Reports, to execute and deliver this Agreement and to
issue, sell and deliver the Purchased Securities as contemplated herein. Contango is duly qualified to do business as a foreign corporation and is in good standing in each jurisdiction where the ownership or leasing of its properties and assets or
the conduct of its business requires such qualification, except where the failure to be so qualified and in good standing would not, individually or in the aggregate, reasonably be expected to either (i) have a material adverse effect on the
business, properties, condition (financial or otherwise), liquidity, results of operations or prospects of Contango and the Subsidiaries taken as a whole or (ii) prevent or materially interfere with consummation of the transactions contemplated
hereby (the occurrence of any such effect or any such prevention or interference described in the foregoing clauses (i) and (ii) being herein referred to as a “Material Adverse Effect”). 

Section 3.02 Subsidiaries. Contango owns, directly or indirectly, the issued and outstanding capital stock,
membership interests, partnership interests or other ownership interests (as applicable) of each of the entities listed on Schedule B hereto in the percentages set forth on Schedule B hereto, which constitute all
direct or indirect subsidiaries of Contango. References herein to “Subsidiaries” refer to the entities listed on Schedule B hereto. Each Subsidiary has been duly organized and is validly existing and in good standing under
the laws of the jurisdiction of its organization, with full power and authority to own, lease and operate its properties and assets and to conduct its business as described in the SEC Reports, except where the failure to be in good standing would
not have a Material Adverse Effect. Each Subsidiary is duly qualified to do business and is in good standing in each jurisdiction where the ownership or leasing of its properties and assets or the conduct of its business requires such qualification,
except where the failure to be so qualified and in good standing would not, individually or in the aggregate, have a Material Adverse Effect. Except as disclosed in the SEC Reports, all of the outstanding shares of capital stock of, or other equity
interests in, each of the Subsidiaries have been duly authorized and validly issued, are fully paid and non-assessable, have been issued in compliance with all applicable securities laws, were not
issued in violation of any preemptive right, resale right, right of first refusal or similar right and are owned by Contango or applicable Subsidiary subject to no security interest, other encumbrance or adverse claims, except for such liens,
encumbrances, equities or claims granted in connection with that certain Credit Agreement, dated as of September 17, 2019, among Contango, as borrower, JPMorgan Chase Bank, N.A., as administrative agent, and each of JPMorgan Chase Bank, N.A.,
Royal Bank of Canada and Cadence Bank, N.A., as joint bookrunners and the lenders from time to time party thereto, and as amended, restated or modified from time to time (collectively, the “Credit Agreement”), or as could not, in
the aggregate, reasonably be expected to have a Material Adverse Effect. No options, warrants or other rights to purchase, agreements or other obligations to issue or other rights to convert any obligation into shares of capital stock of, or equity
interests in, the Subsidiaries are outstanding. Contango owns, directly or indirectly, 37% of the outstanding limited liability company interests in Exaro Energy III LLC, a Delaware limited liability company, and such limited liability company
interests are owned by Contango subject to no security interest, other encumbrance or adverse claims, except for such liens, encumbrances, equities or claims granted in connection with the Credit Agreement or as could not, in the aggregate,
reasonably be expected to have a Material Adverse Effect. 

  
 8 

 Section 3.03 Capitalization. As of the date of this Agreement,
Contango has 200,000,000 shares of Common Stock and 5,000,000 shares of preferred stock authorized and, prior to the issuance and sale of the Purchased Securities as contemplated hereby and assuming conversion of all outstanding shares of the
Company’s Series A Contingent Convertible Preferred Stock and Series B Contingent Convertible Preferred Stock, has 108,334,045 shares of Common Stock issued and outstanding. All of the issued and outstanding shares of capital stock of Contango
have been duly authorized and validly issued and are fully paid and non-assessable, have been issued in compliance with all applicable securities laws and were not issued in violation of any
preemptive right, resale right, right of first refusal or similar right. 
 Section 3.04 Listing. The Common
Stock is duly listed, and admitted and authorized for trading, on the NYSE American. Contango has not received any notice from the NYSE American regarding the delisting or potential delisting of the Common Stock from the NYSE American. Prior to the
conversion of the Purchased Securities in accordance with the Statement of Resolution, Contango shall apply to list or quote all of the Conversion Shares on the national stock exchange on which the Common Stock is then listed and promptly secure the
listing of all of the Conversion Shares. Contango hereby agrees to use commercially reasonable efforts to maintain the listing or quotation of the Common Stock, including the Conversion Shares when listed, on the NYSE American and will comply in all
respects with Contango’s reporting, filing and other obligations under the rules and regulations of the NYSE American. Contango further agrees, if Contango applies to have the Common Stock traded on any other trading market, it will then
include in such application all of the Conversion Shares, and will take such other action as is necessary to cause all of the Conversion Shares to be listed or quoted on such other trading market as promptly as possible. For so long as Contango
maintains a listing or quotation of the Common Stock on the NYSE American or any other trading market, Contango agrees to maintain the eligibility of the Common Stock for electronic transfer through the Depository Trust Company or another
established clearing corporation, including, without limitation, by timely payment of fees to the Depository Trust Company or such other established clearing corporation in connection with such electronic transfer. 

Section 3.05 Valid Issuance of Purchased Securities. The Purchased Securities have been duly and validly
authorized and, when issued and delivered against payment therefor as provided herein, will be duly and validly issued, fully paid and non-assessable and free of statutory and contractual preemptive

as amended (“Contango Bylaws”), or any agreement or other instrument to which Contango is a party. No holder of Purchased Securities will be subject to personal liability by reason of being such a holder.

applicable to it or any of its properties, except, in the case of clauses (B), (C), (D) and (E), to the extent that any such conflict, breach, violation or default would not reasonably be expected to have a Material Adverse Effect.

Effect.

 Section 3.12 Internal Controls. Contango and each of its
Subsidiaries maintain effective internal control over financial reporting (as defined in Rules 13a-15 and 15d-15 under the Exchange Act) and a system of internal
accounting controls sufficient to provide reasonable assurance that: (i) transactions are executed in accordance with management’s general or specific authorization; (ii) transactions are recorded as necessary to permit preparation of
financial statements in conformity with GAAP and to maintain accountability for assets; (iii) access to assets is permitted only in accordance with management’s general or specific authorization; and (iv) the recorded accountability
for assets is compared with existing assets at reasonable intervals and appropriate action is taken with respect to any differences. Contango’s independent registered public accountants and the Audit Committee of the Board of Directors of
Contango have been advised of (1) all significant deficiencies and material weaknesses, if any, in the design or operation of Contango’s internal control over financial reporting (whether or not remediated) and (2) all fraud, if any,
whether or not material, that involves management or other employees who have a role in Contango’s internal control over financial reporting. All significant deficiencies and material weaknesses, if any, in Contango’s internal control over
financial reporting are disclosed SEC Reports. Since the end of Contango’s most recent audited fiscal year, except as disclosed in the SEC Reports, there have not been any changes in Contango’s internal control over financial reporting
that have materially affected, or are reasonably likely to materially affect, the Contango’s internal control over financial reporting. 

Section 3.13 Disclosure Controls. Contango and each of its Subsidiaries maintain effective disclosure controls and
procedures (as defined in Rules 13a-15 and 15d-15 under the Exchange Act) designed to ensure that information required to be disclosed by Contango in the reports it

executive officer and its principal financial officer, as appropriate, to allow timely decisions regarding disclosure.

Subsidiaries included or incorporated by reference in the SEC Reports, including, without limitation, production, costs of operation and development, current prices for production, agreements relating to current and future operations and sales of
production, was true and correct in all material respects on the dates such estimates were made and such information was supplied and was prepared in accordance with customary industry practices. Other than normal production of reserves, intervening
market commodity price fluctuations, fluctuations in demand for such products, adverse weather conditions, unavailability or increased costs of rigs, equipment, supplies or personnel, the timing of third party operations and other factors, changes
in applicable regulations or regulatory guidance regarding the rules for estimating reserves, in each case in the ordinary course of business, and the acquisition of the White Star Properties, and except as described in the SEC Reports, neither of
Contango nor any of the Subsidiaries is aware of any facts or circumstances that would result in a material adverse change in the aggregate net reserves, or the aggregate present value of future net cash flows therefrom, as described in the SEC
Reports.

(i) all royalties, rentals, deposits and other amounts owed under the oil and gas leases constituting the oil and gas properties of Contango and the Subsidiaries have been properly and timely paid (other than amounts held in suspense accounts

amount of proceeds from the sale or production attributable to the oil and gas properties of Contango and the Subsidiaries are currently being held in suspense by any purchaser thereof, except where such amounts due would not reasonably be expected
to have a Material Adverse Effect, and (ii) there are no claims under take-or-pay contracts pursuant to which natural gas purchasers have any makeup
rights affecting the interests of Contango or the Subsidiaries in their respective oil and gas properties, except where such claims would not reasonably be expected to have a Material Adverse Effect. 

Section 3.21 Intellectual Property. Each of Contango and the Subsidiaries owns, licenses or otherwise has the
right to use all inventions, patent applications, patents, trademarks (both registered and unregistered), trade names, service names, know-how (including trade secrets and other unpatented and/or
unpatentable proprietary or confidential information, systems or procedures), copyrights, service marks and other intellectual property as described in the SEC Reports and which is necessary for the conduct of, or material to, its business

concerning the employees of Contango or any of the Subsidiaries. 
 Section 3.23 Environmental Matters. Contango
and the Subsidiaries and their respective properties, assets and operations are in compliance with, and Contango and each of the Subsidiaries hold all permits, authorizations and approvals required under, Environmental Laws (as defined below),
except to the extent that failure to so comply or to hold such permits, authorizations or approvals would not, individually or in the aggregate, have a Material Adverse Effect. There are no past or present conditions, circumstances, activities,
practices, actions, omissions or plans that could reasonably be expected to give rise to any material costs or liabilities to Contango or any Subsidiary under, or to interfere with or prevent compliance by Contango or any Subsidiary with,
Environmental Laws. Except as would not, individually or in the aggregate, have a Material Adverse Effect, neither Contango nor any of the Subsidiaries (i) is the subject of any investigation, (ii) has received any notice or claim,
(iii) is a party to or affected by any pending or, to Contango’s knowledge, threatened action, suit or proceeding, (iv) is bound by any decree, judgment or order or (v) has entered into any agreement, in each case relating to any
actual or alleged violation of any Environmental Law or any actual or alleged release or threatened release or cleanup at any location of any Hazardous Materials (as defined below) (as used herein, “Environmental Law” means any U.S.
federal, state, local or foreign law, statute, ordinance, rule, regulation, order, decree, judgment, injunction, permit, license, authorization or other binding requirement, or common law, relating to the protection of human health, the environment

to protect Contango and the Subsidiaries and their respective properties, assets, operations, personnel and businesses in all material respects. All such insurance is fully in force. Neither Contango nor any Subsidiary has reason to believe that it
will not be able to renew any such insurance as and when such insurance expires.

Contango will not directly or indirectly use the proceeds of the offering hereunder, or lend, contribute or otherwise make available such proceeds to any subsidiary, joint venture partner or other person or entity (i) to fund any activities of

currently prohibited, directly or indirectly, from paying any dividends or making other distributions to Contango, from repaying to Contango any loans or advances to such Subsidiary from Contango or from transferring any of such Subsidiary’s
properties or assets to Contango or any other Subsidiary of Contango, except, in each case, as described in the SEC Reports. 

Section 3.31 No Preemptive Rights. The issuance and sale of the Purchased Securities will not cause any holder of

capital stock of Contango. 
 Section 3.32 Certain Fees. Other than fees or commissions paid or to be paid to

the consummation of the transactions contemplated by this Agreement. 
 Section 3.33 Stabilization. Neither
Contango nor any of the Subsidiaries nor any of their respective directors, officers, Affiliates or controlling Persons has taken, directly or indirectly, any action that is designed, or might reasonably be expected, to cause or result in, or any

reasonably be expected to have a Material Adverse Effect.

of the representations and warranties of the Purchasers contained in Section 4.05, the issuance and sale of the Purchased Securities pursuant to this Agreement is exempt from registration requirements of the Securities Act,
and Contango has not taken nor will take any action hereafter that would cause the loss of such exemption. 

  
 18 

 Section 3.36 No Integration. Contango has not, directly or
through any agent, issued, sold, offered for sale, solicited offers to buy or otherwise negotiated in respect of, any security (as defined in the Securities Act), that is or will be integrated with the issuance and sale of the Purchased Securities

Disqualification Event relating to any Issuer Covered Person. 
 Section 3.38 No General Solicitation. Neither
Contango, any of its Affiliates nor any Person acting on behalf of Contango has offered or sold any of the Purchased Securities by any form of general solicitation or general advertising. Contango has offered the Purchased Securities for sale only

 19 

 Section 3.41 Disclosure. On or before 9:30 a.m., New York local

file a Current Report on Form 8-K with SEC describing the terms of the transactions contemplated by the Basic Documents in the form required by the Exchange Act. Contango and each Purchaser shall consult with
each other in issuing any other press releases with respect to the transactions contemplated hereby, and neither Contango nor any Purchaser shall issue any such press release nor otherwise make any such public statement without the prior consent of
Contango, with respect to any press release of any Purchaser, or without the prior consent of each Purchaser, with respect to any press release of Contango, which consent shall not unreasonably be withheld or delayed, except if such disclosure is
required by law, in which case the disclosing party shall promptly provide the other party with prior notice of such public statement or communication. Notwithstanding the foregoing, Contango shall not publicly disclose the name of any Purchaser, or
include the name of any Purchaser in any filing with the SEC or any regulatory agency or NYSE American, without the prior written consent of such Purchaser, except (a) as required by federal securities law in connection with the filing of the
Basic Documents with the SEC and (b) to the extent such disclosure is required by law or NYSE American regulations, in which case Contango shall provide the Purchasers with prior notice of such disclosure permitted under this clause (b). 

Section 3.42 Information on Shareholdings. After the Closing, Contango shall promptly and accurately respond, and
shall use its commercially reasonable efforts to cause its transfer agent to respond, to reasonable requests for information (which is otherwise not publicly available) made by a Purchaser or its auditors relating to the actual holdings of such
Purchaser or its accounts; provided that Contango shall not be obligated to provide any information that could reasonably result in a violation of applicable law or conflict with Contango’s insider trading policy or a confidentiality obligation
of the Contango. 
 Section 3.43 Removal of Legend. In connection with a sale of the Conversion Shares by a
Purchaser in reliance on Rule 144, the applicable Purchaser or its broker shall deliver to the transfer agent and Contango a seller or broker representation letter, as applicable, providing to the transfer agent and Contango any information deemed
reasonably necessary to determine that the sale of the Conversion Shares is made in compliance with Rule 144, including, as may be appropriate, a certification that the Purchaser is not an Affiliate of Contango and regarding the length of time the
Conversion Shares have been held. Upon receipt of such representation letter, Contango shall promptly direct its transfer agent to remove the notation of a restrictive legend in such Purchaser’s book-entry account maintained by the transfer
agent, including the legend referred to in Section 4.05(d), and Contango shall bear all costs associated therewith. After a registration statement under the Securities Act permitting the public resale of the Conversion Shares has become
effective or any Purchaser or its permitted assigns have held the Conversion Shares for one year, if the book-entry account of such Conversion Shares still bears the notation 

  
 20 

 
of the restrictive legend referred to in Section 4.05(d), Contango agrees, upon request of the Purchaser or permitted assignee, to take all steps necessary to promptly effect the removal of
the legend described in Section 4.05(d) from the Conversion Shares, and Contango shall bear all costs associated therewith, regardless of whether the request is made in connection with a sale or otherwise, so long as such Purchaser or its
permitted assigns provide to Contango any information deemed reasonably necessary to determine that the legend is no longer required under the Securities Act or applicable state laws, including (if there is no such registration statement) a
certification that the holder is not an Affiliate of Contango and regarding the length of time the Conversion Shares have been held.

consummation by it of the transactions contemplated hereby and thereby have been duly and validly authorized by all necessary legal action, and no further consent or authorization of such Purchaser is required. This Agreement to which such Purchaser
is a party has been duly and validly authorized, executed and delivered by such Purchaser and constitutes the legal, valid and binding obligation of such Purchaser and, when executed by such Purchaser, the other Basic Documents to which such
Purchaser is a party will be duly and validly authorized, executed and delivered by such Purchaser and will constitute the legal, valid and binding obligations of such Purchaser, in each case enforceable in accordance with their terms, except as
such enforceability may be limited by bankruptcy, insolvency, fraudulent transfer and similar laws affecting creditors’ rights generally or by general principles of equity and except as the rights to indemnification may be limited by applicable
law. 
 Section 4.03 No Breach. The execution, delivery and performance by such Purchaser of the Basic Documents
and the consummation by such Purchaser of the transactions contemplated hereby or thereby does not and will not (a) assuming the accuracy of the representations and warranties of Contango contained herein and its compliance with the covenants
contained herein, violate any provision of any Law or permit having applicability to such Purchaser or the property or assets of such Purchaser, (b) conflict with or result in a violation or breach of any provision of

  
 21 

 
the organizational documents of such Purchaser, or (c) conflict with or result in a breach or violation of any of the terms or provisions of, or constitute a default under, any material
agreement to which such Purchaser is a party or by which such Purchaser is bound or to which any of the property or assets of such Purchaser is subject, except in the case of clauses (a) and (c), for such conflicts, breaches, violations or
defaults as would not have a material adverse effect on the ability of such Purchaser to consummate the transactions contemplated by the Basic Documents. 

Section 4.04 Certain Fees. No fees or commissions are or will be payable by such Purchaser to brokers, finders or
investment bankers with respect to the purchase of any of the Purchased Securities or the consummation of the transactions contemplated by this Agreement. 

Section 4.05 Unregistered Securities. 

(a) Accredited Investor Status; Sophisticated Purchasers. Such Purchaser is an “accredited investor” within
the meaning of Rule 501 under the Securities Act and is able to bear the risk of its investment in Purchased Securities and the Conversion Shares. Such Purchaser has such knowledge and experience in financial and business matters that it is capable
of evaluating the merits and risks of the purchase of the Purchased Securities and the Conversion Shares. 
 (b)
Information. Such Purchaser and its Representatives have been furnished with all materials relating to the business, finances and operations of Contango that have been requested and materials relating to the offer and sale of the Purchased
Securities that have been requested by such Purchaser and its Representatives. Such Purchaser and its Representatives have been afforded the opportunity to ask questions of Contango. Neither such inquiries nor any other due diligence investigations
conducted at any time by such Purchaser and its Representatives shall modify, amend or affect such Purchaser’s right (i) to rely on Contango’s representations and warranties contained in Article III above or (ii) to
indemnification or any other remedy based on, or with respect to the accuracy or inaccuracy of, or compliance with, the representations, warranties, covenants and agreements in this Agreement, or any other Basic Document. Such Purchaser understands
that the purchase of the Purchased Securities involves a high degree of risk. Such Purchaser has sought such accounting, legal and tax advice as it has considered necessary to make an informed investment decision with respect to its acquisition of
the Purchased Securities. 
 (c) Cooperation. Such Purchaser shall cooperate reasonably with Contango to provide any
information necessary for any applicable securities filings required to be made by Contango in connection with the transactions contemplated hereby. 

(d) Legends. Such Purchaser understands that the Purchased Securities will bear a restrictive legend substantially in
the form as set forth in the Statement of Resolution. 
 (e) Purpose of Purchase. Such Purchaser is purchasing the
Purchased Securities for its own account and not with a view to distribution in violation of any securities laws. Such Purchaser has been advised and understands that none of the Purchased Securities or the Conversion Shares have been registered
under the Securities Act or under the “blue sky” laws of any jurisdiction and may be resold only if registered pursuant to the provisions of the Securities Act (or if eligible, pursuant to the provisions of Rule 144 promulgated under the
Securities Act or pursuant to another available exemption from the registration requirements of the Securities Act). 

  
 22 

 (f) Rule 144. Such Purchaser understands that there is no public
trading market for the Purchased Securities, that none is expected to develop and that the Purchased Securities must be held indefinitely unless and until the Purchased Securities or the Conversion Shares, as applicable, are registered for resale
under the Securities Act or an exemption from such registration is available. Such Purchaser has been advised by its advisors of and is aware of the provisions of Rule 144 promulgated under the Securities Act. 

(g) Reliance by Contango. Such Purchaser understands that the Purchased Securities are being offered and sold in
reliance on transactional exemptions from the registration requirements of federal and state securities laws and that Contango is relying upon the truth and accuracy of the representations, warranties, covenants, acknowledgments and understandings
of such Purchaser set forth herein in order to determine the applicability of such exemptions and the suitability of such Purchaser to acquire the Purchased Securities and the Conversion Shares. 

Section 4.06 No Legal, Tax or Investment Advice. Such Purchaser understands that nothing in this Agreement or any
other materials presented by or on behalf of Contango to the Purchaser in connection with the offer and sale of the Purchased Securities constitutes legal, tax or investment advice. Such Purchaser has consulted such legal, tax and investment
advisors as it, in its sole discretion, has deemed necessary or appropriate in connection with its purchase of the Purchased Securities. Such Purchaser understands that Cowen and Company LLC and Intrepid Partners, LLC (the “Placement
Agents”) have acted solely as the agents of Contango in this placement of the Purchased Securities, and that the Placement Agents make no representation or warranty with regard to the merits of this transaction or as to the accuracy of any
information such Purchaser may have received in connection therewith. Such Purchaser acknowledges that it has not relied on any information or advice furnished by or on behalf of the Placement Agents. 

Section 4.07 Short Selling. Such Purchaser has not engaged in any Short Sales involving Common Stock owned by it
between the time it first began discussions with Contango about the transaction contemplated by this Agreement and the date of execution of this Agreement. 

Section 4.08 Lock-Up Agreement. Without the prior written consent of
Contango, except as otherwise specifically provided in this Agreement, each Purchaser will not, during the period commencing on the Closing Date and ending the date that is six months after the Closing Date, (i) offer, sell, contract to sell,
sell any option or contract to purchase, purchase any option or contract to sell, grant any option, right or warrant to purchase, lend, or otherwise transfer or dispose of, directly or indirectly, any of its Purchased Securities or (ii) enter
into any swap or other transaction or arrangement that transfers or that is designed to, or that might reasonably be expected to, result in the transfer to another, in whole or in part, any of the economic consequences of ownership of its Purchased
Securities, whether any such transaction described in clause (i) or (ii) above (any such transaction described in clauses (i) and (ii), a “Transfer”) is to be settled by delivery of Purchased Securities, Common Stock or
such other securities, in cash or otherwise. 

  
 23 

 ARTICLE V 

INDEMNIFICATION 

Section 5.01 Indemnification by Contango. Contango agrees to indemnify each Purchaser and its Representatives
(collectively, “Purchaser Related Parties”) from, and hold each of them harmless against, any and all losses, actions, suits, proceedings (including any investigations, litigation or inquiries), demands and causes of action, and, in
connection therewith, and promptly upon demand, pay or reimburse each of them for all reasonable costs, losses, liabilities, damages or expenses of any kind or nature whatsoever (including the reasonable fees and disbursements of counsel and all
other reasonable expenses incurred in connection with investigating, defending or preparing to defend any such matter that may be incurred by them or asserted against or involve any of them), involving a third party claim, as a result of, arising
out of, or in any way related to (i) the failure of any of the representations or warranties made by Contango contained herein to be true and correct in all material respects as of the date hereof (except with respect to any provisions
including the word “material” or words of similar import, with respect to which such representations and warranties must have been true and correct) or (ii) the material breach of any covenants of Contango contained herein,
provided that, in the case of the immediately preceding clause (i), such claim for indemnification is made prior to the expiration of such representation or warranty; provided, however, that for purposes of determining when an
indemnification claim has been made, the date upon which a Purchaser Related Party shall have given notice (stating in reasonable detail the basis of the claim for indemnification) to Contango shall constitute the date upon which such claim has been
made. 
 Section 5.02 Indemnification by the Purchasers. Each Purchaser agrees, severally and not jointly, to
indemnify Contango and its respective Representatives (collectively, “Contango Related Parties”) from, and hold each of them harmless against, any and all losses, actions, suits, proceedings (including any investigations,
litigation or inquiries), demands and causes of action, and, in connection therewith, and promptly upon demand, pay or reimburse each of them for all reasonable costs, losses, liabilities, damages or expenses of any kind or nature whatsoever
(including the reasonable fees and disbursements of counsel and all other reasonable expenses incurred in connection with investigating, defending or preparing to defend any such matter that may be incurred by them or asserted against or involve any
of them), involving a third party claim, as a result of, arising out of, or in any way related to (i) the failure of any of the representations or warranties made by such Purchaser contained herein to be true and correct in all material
respects as of the date hereof or (ii) the material breach of any of the covenants of such Purchaser contained herein, provided that, in the case of the immediately preceding clause (i), such claim for indemnification relating to a
breach of any representation or warranty is made prior to the expiration of such representation or warranty; provided, however, that for purposes of determining when an indemnification claim has been made, the date upon which a
Contango Related Party shall have given notice (stating in reasonable detail the basis of the claim for indemnification) to such Purchaser shall constitute the date upon which such claim has been made; provided, further, that the
liability of such Purchaser shall not be greater in amount than such Purchaser’s Allocated Purchase Price. 

  
 24 

 Section 5.03 Indemnification Procedure. A claim for
indemnification for any matter not involving a third party claim may be asserted by notice to the party from whom indemnification is sought; provided, however, that failure to so notify the Indemnifying Party shall not preclude the
Indemnified Party from any indemnification which it may claim in accordance with this Article V, except as otherwise provided in Sections 5.01 and 5.02. Promptly after any Contango Related Party or Purchaser Related Party
(hereinafter, the “Indemnified Party”) has received notice of any indemnifiable claim hereunder, or the commencement of any action, suit or proceeding by a third Person, which the Indemnified Party believes in good faith is an
indemnifiable claim under this Agreement, the Indemnified Party shall give the indemnitor hereunder (the “Indemnifying Party”) written notice of such claim or the commencement of such action, suit or proceeding, but failure to so
notify the Indemnifying Party will not relieve the Indemnifying Party from any liability it may have to such Indemnified Party hereunder except to the extent that the Indemnifying Party is materially prejudiced by such failure. Such notice shall
state the nature and the basis of such claim to the extent then known. The Indemnifying Party shall have the right to defend and settle, at its own expense and by its own counsel, any such matter as long as the Indemnifying Party pursues the same
diligently and in good faith. If the Indemnifying Party undertakes to defend or settle such claim, it shall promptly after such determination, and in no event later than five (5) days, notify the Indemnified Party of its intention to do so, and
the Indemnified Party shall cooperate with the Indemnifying Party and its counsel in all commercially reasonable respects in the defense thereof and/or the settlement thereof. Such cooperation shall include, but shall not be limited to, furnishing
the Indemnifying Party with any books, records and other information reasonably requested by the Indemnifying Party and in the Indemnified Party’s possession or control relevant to the claim. Such cooperation of the Indemnified Party shall be
at the cost of the Indemnifying Party. After the Indemnifying Party has notified the Indemnified Party of its intention to undertake to defend or settle any such asserted liability, and for so long as the Indemnifying Party diligently pursues such
defense, the Indemnifying Party shall not be liable for any additional legal expenses incurred by the Indemnified Party in connection with any defense or settlement of such asserted liability; provided, however, that the Indemnified
Party shall be entitled (i) at its expense, to participate in the defense of such asserted liability and the negotiations of the settlement thereof and (ii) if (A) the Indemnifying Party has, within ten (10) Business Days of when the
Indemnified Party provides written notice of a claim, failed (y) to assume the defense or settlement of such claim and employ counsel or (z) to notify the Indemnified Party of such assumption, or (B) if the defendants in any such
action include both the Indemnified Party and the Indemnifying Party and counsel to the Indemnified Party shall have concluded that there may be reasonable defenses available to the Indemnified Party that are different from or in addition to those
available to the Indemnifying Party or if the interests of the Indemnified Party reasonably may be deemed to conflict with the interests of the Indemnifying Party, then the Indemnified Party shall have the right to select a separate

  
 25 

 
counsel and to assume such legal defense and otherwise to participate in the defense of such action, with the expenses and fees of such separate counsel and other expenses related to such
participation to be reimbursed by the Indemnifying Party as incurred. Notwithstanding any other provision of this Agreement, the Indemnifying Party shall not settle any indemnified claim without the consent of the Indemnified Party, unless the
settlement thereof imposes no liability or obligation on, and includes a complete release from liability of, and does not contain any admission of wrong doing by, the Indemnified Party. 

Section 5.04 Tax Treatment of Indemnification Payments. Any indemnification payments made under this Article
V shall be treated for all tax purposes as an adjustment to the relevant Purchaser’s Allocated Purchase Price except as otherwise required by applicable Law. 

ARTICLE VI 
 TERMINATION

 Section 6.01 Termination. Notwithstanding anything in this Agreement to the contrary, this Agreement may
be terminated at any time: 
 (a) by any Purchaser (with respect to the obligations of such Purchaser) or Contango, upon
written notice to the other party, if the Closing shall not have occurred on or before December 27, 2019 (the “Outside Date”); provided, however, that the right to terminate this Agreement under this Section 6.01(a) shall
not be available to any party whose (i) breach of any provision of this Agreement, (ii) failure to comply with its obligations under this Agreement or (iii) actions not taken in good faith shall have been the cause of, or shall have
resulted in, the failure of the Closing to occur on or prior to the Outside Date or the failure of a condition in Section 2.04(b) or Section 2.04(c) to be satisfied at such time; or 

(b) by either Contango or any Purchaser (with respect to the obligations of such Purchaser) if any court of competent
jurisdiction in the United States or other United States Regulatory Authority shall have issued a final order, decree or ruling or taken any other final action restraining, enjoining or otherwise prohibiting the transactions contemplated hereby and
such order, decree, ruling or other action is or shall have become final and nonappealable. 
 Section 6.02 Certain
Effects of Termination. If this Agreement is terminated as provided in Section 6.01, except as set forth in Section 7.03, this Agreement shall become null and void and have no further force or
effect, but the parties shall not be released from any liability arising from or in connection with any breach hereof occurring prior to such termination. 

ARTICLE VII 

MISCELLANEOUS 

Section 7.01 Expenses. All other costs and expenses, including, without limitation, fees and disbursements of
counsel, financial advisors and accountants, incurred in connection with this Agreement and the transactions contemplated hereby shall be paid by the party incurring such costs and expenses, whether or not the Closing shall have occurred. 

  
 26 

 Section 7.02 Interpretation. Article, Section, Schedule and
Exhibit references in this Agreement are references to the corresponding Article, Section, Schedule or Exhibit to this Agreement, unless otherwise specified. All Exhibits and Schedules to this Agreement are hereby incorporated and made a part hereof
as if set forth in full herein and are an integral part of this Agreement. All references to instruments, documents, contracts and agreements are references to such instruments, documents, contracts and agreements as the same may be amended,
supplemented and otherwise modified from time to time, unless otherwise specified. The word “including” shall mean “including but not limited to” and shall not be construed to limit any general statement that it follows to the
specific or similar items or matters immediately following it. Whenever Contango has an obligation under the Basic Documents, the expense of complying with that obligation shall be an expense of Contango unless otherwise specified. Any reference in
this Agreement to $ shall mean U.S. dollars. Whenever any determination, consent or approval is to be made or given by any Purchaser, such action shall be in such Purchaser’s sole discretion, unless otherwise specified in this Agreement. If any
provision in the Basic Documents is held to be illegal, invalid, not binding or unenforceable, (i) such provision shall be fully severable and the Basic Documents shall be construed and enforced as if such illegal, invalid, not binding or
unenforceable provision had never comprised a part of the Basic Documents, and the remaining provisions shall remain in full force and effect and (ii) the parties hereto shall negotiate in good faith to modify the Basic Documents so as to
effect the original intent of the parties as closely as possible in an acceptable manner in order that the transactions contemplated hereby are consummated as originally contemplated to the greatest extent possible. When calculating the period of
time before which, within which or following which any act is to be done or step taken pursuant to the Basic Documents, the date that is the reference date in calculating such period shall be excluded. If the last day of such period is a non-Business Day, the period in question shall end on the next succeeding Business Day. Any words imparting the singular number only shall include the plural and vice versa. The words such as “herein,”
“hereinafter,” “hereof” and “hereunder” refer to this Agreement as a whole and not merely to a subdivision in which such words appear unless the context otherwise requires. The provision of a Table of Contents, the
division of this Agreement into Articles, Sections and other subdivisions and the insertion of headings are for convenience of reference only and shall not affect or be utilized in construing or interpreting this Agreement. 

Section 7.03 Survival of Provisions. The representations and warranties set forth in Sections 3.01,
3.02, 3.03, 3.05, 3.06, 3.30, 4.02, 4.04 and 4.05 hereunder shall survive the execution and delivery of this Agreement for a period of one (1) year, and the other representations and
warranties set forth herein shall survive for a period of six (6) months following the final Closing Date regardless of any investigation made by or on behalf of Contango or a Purchaser. The covenants made in this Agreement shall survive the
final Closing and remain operative and in full force and effect regardless of acceptance of any of the Purchased Securities and payment therefor and repayment, conversion or repurchase thereof. Regardless of any purported general

  
 27 

 
termination of this Agreement, the provisions of Article V and all indemnification rights and obligations of Contango and the Purchasers thereunder, Section 6.02
and this Article VII shall remain operative and in full force and effect as between Contango and each Purchaser, unless Contango and each Purchaser execute a writing that expressly (with specific references to the applicable Section or
subsection of this Agreement) terminates such rights and obligations as between Contango and such Purchaser. 

Section 7.04 No Waiver; Modifications in Writing. 

(a) Delay. No failure or delay on the part of any party in exercising any right, power or remedy hereunder shall operate
as a waiver thereof, nor shall any single or partial exercise of any such right, power or remedy preclude any other or further exercise thereof or the exercise of any other right, power or remedy. The remedies provided for herein are cumulative and
are not exclusive of any remedies that may be available to a party at law or in equity or otherwise. 
 (b) Specific
Waiver. Except as otherwise provided herein, no amendment, waiver, consent, modification or termination of any provision of this Agreement or any other Basic Document shall be effective unless signed by each of the parties hereto or thereto
affected by such amendment, waiver, consent, modification or termination. Any amendment, supplement or modification of or to any provision of this Agreement or any other Basic Document, any waiver of any provision of this Agreement or any other
Basic Document and any consent to any departure by Contango from the terms of any provision of this Agreement or any other Basic Document shall be effective only in the specific instance and for the specific purpose for which made or given. Except
where notice is specifically required by this Agreement, no notice to or demand on Contango in any case shall entitle Contango to any other or further notice or demand in similar or other circumstances. Any investigation by or on behalf of any party
shall not be deemed to constitute a waiver by the party taking such action of compliance with any representation, warranty, covenant or agreement contained herein. Notwithstanding any of the foregoing, any amendment, waiver, consent or modification
of, or supplement to, this Agreement or any other Basic Document shall require approval of a majority of the members of the board of directors of Contango not affiliated with John C. Goff. 

Section 7.05 Binding Effect; Assignment. 

(a) Binding Effect. This Agreement shall be binding upon Contango, each Purchaser and their respective successors and
permitted assigns. Except as expressly provided in this Agreement, this Agreement shall not be construed so as to confer any right or benefit upon any Person other than the parties to this Agreement and their respective successors and permitted
assigns; provided that, the representations and warranties of Contango in Article III and the representations and warranties of the Purchasers in Article IV may be relied upon by the Placement Agents, in their capacity as placement agents for
the offering and sale of the Purchased Securities, as third party beneficiaries thereof. 

  
 28 

 (b) Assignment of Rights. Without the written consent of Contango, no
portion of the rights and obligations of any Purchaser under this Agreement may be assigned or transferred by such Purchaser. No portion of the rights and obligations of Contango under this Agreement may be transferred or assigned without the prior
written consent of the Purchasers.

Any action against any party relating to the foregoing shall be brought in any federal or state court of competent jurisdiction located within the State of Texas, and the parties hereto hereby irrevocably submit to the
non-exclusive jurisdiction of any federal or state court located within the State of Texas over any such action. The parties hereby irrevocably waive, to the fullest extent permitted by applicable Law, any
objection which they may now or hereafter have to the laying of venue of any such dispute brought in such court or any defense of inconvenient forum for the maintenance of such dispute. Each of the parties hereto agrees that a judgment in any such
dispute may be enforced in other jurisdictions by suit on the judgment or in any other manner provided by Law.

request of any such other party. 

  
 30

 ARTICLE
II 
 REGISTRATION RIGHTS 

Section 2.1 Shelf Registration. 

(a) Shelf Registration. Contango shall use its commercially reasonable efforts to prepare and file an initial Shelf
Registration Statement under the Securities Act covering all Registrable Securities at such time of filing within 30 days of the date on which the shares of Series C Preferred Stock are first converted into Common Stock (the “Filing
Deadline”); provided Contango may satisfy such requirement by filing a post-effective amendment to an effective Shelf Registration Statement to include the Registrable Securities and, in such case, references to “Shelf Registration
Statement” in this Agreement shall include any such amendment. Contango shall use its commercially reasonable efforts to cause such initial Shelf Registration Statement to become effective on or as soon as practicable after the filing thereof
and no later than 90 days (or if reviewed by the staff of the Commission, 120 days) from the date on which the shares of Series C Preferred Stock are first converted into Common Stock (the “Effectiveness Deadline”). Contango will
use its commercially reasonable efforts to cause such initial Shelf Registration Statement filed pursuant to this Section 2.1(a) to be continuously effective under the Securities Act until the earliest of (1) all
Registrable Securities covered by the Shelf Registration Statement have been distributed in the manner set forth and as contemplated in such Shelf Registration Statement, (2) there are no longer any Registrable Securities outstanding and
(3) three years from the Effective Date (the “Effectiveness Period”). A Shelf Registration Statement filed pursuant to this Section 2.1(a) shall be on such appropriate registration form of the
Commission as shall be selected by Contango. A Shelf Registration Statement when declared effective (including the documents incorporated therein by reference) will comply as to form in all material respects with all applicable requirements of the
Securities Act and the Exchange Act and will not contain an untrue statement of a material fact or omit to state a material fact required to be stated therein or necessary to make the statements therein not misleading (in the case of any prospectus
contained in such Shelf Registration Statement, in the light of the circumstances under which a statement is made). As soon as practicable following the date that a Shelf Registration Statement becomes effective, but in any event within one Business
Day of such date, Contango shall provide the Holders with written notice of the effectiveness of a Shelf Registration Statement. 

  
 4 

 (b) Notwithstanding Contango’s registration obligations set forth in
Section 2.1(a), if the Commission does not permit, as a result of the application of Rule 415, all of the Registrable Securities (after giving effect to all Resale Opt-Out Notices) to
be registered for resale as a secondary offering on a single registration statement, Contango shall use its commercially reasonable efforts to file amendments to the initial Shelf Registration Statement as required by the Commission, covering the
maximum number of Registrable Securities, applied on a pro rata basis among the Holders, permitted by the Commission to be registered on such Shelf Registration Statement. In the event Contango amends the initial Shelf Registration Statement in
accordance with the foregoing, Contango shall use its commercially reasonable efforts to file with the Commission, as promptly as allowed by Commission, one or more Shelf Registration Statements covering those Registrable Securities that were not
registered for resale on the initial Shelf Registration Statement, as amended. 
 (c) Resale Registration Opt-Out. At least three Business Days before the initial filing of the Shelf Registration Statement required by Section 2.1(a), Contango shall provide advance written notice to each
Holder that it plans to file a Shelf Registration Statement. Any Holder may deliver advance written notice (a “Resale Opt-Out Notice”) to Contango requesting that such Holder not be included
in a Shelf Registration Statement prior to its initial filing. Following receipt of a Resale Opt-Out Notice from a Holder, Contango shall not be required to include the Registrable Securities of such Holder in
such Shelf Registration Statement. 
 (d) Delay Rights. Notwithstanding anything to the contrary contained herein,
Contango may, upon written notice to any Selling Holder whose Registrable Securities are included in the Shelf Registration Statement, suspend such Selling Holder’s use of any prospectus which is a part of the Shelf Registration Statement (in
which event the Selling Holder shall discontinue sales of the Registrable Securities pursuant to the Shelf Registration Statement) if (i) Contango is pursuing an acquisition, merger, reorganization, disposition or other similar transaction and
Contango determines in good faith that Contango’s ability to pursue or consummate such a transaction would be materially and adversely affected by any required disclosure of such transaction in the Shelf Registration Statement or
(ii) Contango has experienced some other material non-public event the disclosure of which at such time, in the good faith judgment of Contango, would materially and adversely affect Contango;
provided, however, that in no event shall the Selling Holders be suspended from selling Registrable Securities pursuant to the Shelf Registration Statement for a period of 45 consecutive days or an aggregate of 120 days in any 365-day period. Upon disclosure of such information or the termination of the condition described above, Contango shall provide prompt notice (which notice shall not contain any material, non-public information regarding Contango), to the Selling Holders whose Registrable Securities are included in the Shelf Registration Statement, and shall promptly terminate any suspension of sales it has put into
effect and shall take such other actions necessary or appropriate to permit registered sales of Registrable Securities as contemplated in this Agreement. 

Section 2.2 Piggyback Registration Participation. If at any time Contango proposes to file (i) at a time when
Contango is not a WKSI, a registration statement and such Holder has not previously included its Registrable Securities in a Shelf Registration Statement contemplated by Section 2.1(a) of this Agreement that is currently
effective, or (ii) a prospectus supplement to an 

  
 5 

 
effective “automatic shelf registration statement” (as defined in Rule 405 under the Securities Act), so long as Contango is a WKSI at such time or, whether or not Contango is a WKSI,
so long as the Registrable Securities were previously included in the underlying Shelf Registration Statement, or in any case in which Holders may participate in such offering without the filing of a post-effective amendment, in each case, for the
sale of Common Stock in an Underwritten Offering for its own account and/or another Person, other than (a) a registration relating solely to employee benefit plans, (b) a registration relating solely to a Rule 145 transaction, or
(c) a registration statement on any registration form which does not permit secondary sales, then Contango shall give not less than three Business Days advance notice (including, but not limited to, notification by e-mail; such notice, a “Piggyback Notice”) of such proposed Underwritten Offering to each Holder that, together with its Affiliates, owns more than $2.5 million of Registrable Securities, and
such notice shall offer such Holder the opportunity to participate in any Underwritten Offering and to include in such Underwritten Offering such number of Registrable Securities (the “Included Registrable Securities”) as each such
Holder may request in writing (a “Piggyback Registration”); provided, however, that Contango (A) shall not be required to include the Registrable Securities of the Holders in such Registration if the Holders do
not offer a minimum of $2.5 million of Registrable Securities, or (B) if Contango has been advised by the Managing Underwriter that the inclusion of Registrable Securities for sale for the benefit of the Holders will have material and
adverse effect on the offering price, timing or probability of success of the distribution of the Common Stock in the Underwritten Offering, then the amount of Registrable Securities to be offered for the accounts of Holders shall be determined
based on the provisions of Section 2.2(b). If Contango is not required to offer the opportunity for a Piggyback Registration in respect of a proposed Underwritten Offering as a result of the circumstance described in clause
(B) of the proviso of the immediately preceding sentence, then Contango shall nevertheless be required to furnish to such Holders the Piggyback Notice in respect of such proposed Underwritten Offering, which notice shall describe
Contango’s intention to conduct an Underwritten Offering and, if the determination described in clause (B) of the proviso of the immediately preceding sentence has been made at the time that the Piggyback Notice is required to be given by
Contango, shall include notification that the Holders do not have the opportunity to include Registrable Securities in such Underwritten Offering because Contango has been advised by the Managing Underwriter that the inclusion of Registrable
Securities for sale for the benefit of the Holders will have a material and adverse effect on the offering price, timing or probability of success of the distribution of the Common Stock in the Underwritten Offering. If the circumstance described in
clause (B) of the proviso of the preceding sentence is made after the Piggyback Notice has been given, then Contango shall notify the Holders who were provided such Piggyback Notice (or if the two Business Day period referred to in the next
sentence has lapsed, the Holders who have timely elected to include Registrable Securities in such offering) in writing of such circumstance and the aggregate number of Registrable Securities, if any, that can be included in such offering. Each
Piggyback Notice shall be provided to Holders on a Business Day pursuant to Section 3.1 hereof and confirmation of receipt of such notice shall be requested in the notice. The Holder will have two Business Days after notice
has been delivered to request in writing the inclusion of Registrable Securities in the Underwritten Offering. If no request for inclusion from a Holder is received within the specified time, such Holder shall have no further right to participate in
such Piggyback Registration. If, at any time after giving written notice of its intention to undertake an Underwritten Offering and prior to the closing of such Underwritten Offering, Contango shall determine for any reason not to undertake or to
delay such Underwritten Offering, Contango may, at its election, give 

  
 6 

 
written notice of such determination to the Selling Holders and, (x) in the case of a determination not to undertake such Underwritten Offering, shall be relieved of its obligation to sell
any Included Registrable Securities in connection with such terminated Underwritten Offering, and (y) in the case of a determination to delay such Underwritten Offering, shall be permitted to delay offering any Included Registrable Securities
for the same period as the delay in the Underwritten Offering. Any Selling Holder shall have the right to withdraw such Selling Holder’s request for inclusion of such Selling Holder’s Registrable Securities in such Underwritten Offering by
giving written notice to Contango of such withdrawal up to and including the time of pricing of such offering. Any Holder may deliver written notice (a “Piggyback Opt-Out Notice”) to Contango
requesting that such Holder not receive notice from Contango of any proposed Underwritten Offering; provided, however, that such Holder may later revoke any such Piggyback Opt-Out Notice in writing.
Following receipt of a Piggyback Opt-Out Notice from a Holder (unless subsequently revoked), Contango shall not be required to deliver any notice to such Holder pursuant to this
Section 2.2(a) and such Holder shall no longer be entitled to participate in Underwritten Offerings by Contango pursuant to this Section 2.2(a), unless such Piggyback
Opt-Out Notice is revoked by such Holder. 
 (b) Priority of Piggyback
Registration. If the Managing Underwriter or Underwriters of any proposed Underwritten Offering of shares of Common Stock included in a Piggyback Registration advises Contango that the total shares of Common Stock which the Selling Holders and
any other Persons intend to include in such offering exceeds the number which can be sold in such offering without being likely to have a material and adverse effect on the offering price, timing or probability of success of the distribution of the
Common Stock offered or the market for the Common Stock, then the Piggyback Notice provided by Contango pursuant to Section 2.2(a) shall include notification of such determination or, if such determination is made after the
Piggyback Notice has been given, then Contango shall furnish notice in writing (including by e-mail) to the Holders (or to those who have timely elected to participate in such Underwritten Offering), and the
Common Stock to be included in such Underwritten Offering shall include the number of shares of Common Stock that such Managing Underwriter or Underwriters advises Contango can be sold without having such material and adverse effect, with such
number to be allocated (i) if such Piggyback Registration was initiated by Contango, (A) first, to Contango, (B) second, pro rata among the Selling Holders and any other Persons who have been or after the date hereof are granted
registration rights on parity with the registration rights granted under this Agreement (the “Other Holders”) who have requested participation in the Piggyback Registration (based, for each such Selling Holder or Other Holder, on
the percentage derived by dividing (1) the number of shares of Common Stock proposed to be sold by such Selling Holder or such Other Holder in such offering; by (2) the aggregate number of shares of Common Stock proposed to be sold by all
Selling Holders and all Other Holders in the Piggyback Registration), and (C) third, to any other holder of shares of common stock with registration rights that are subordinate to the rights of the Holders hereunder and (ii) if such
Piggyback Registration was not initiated by Contango, (A) first, to the Persons initiating such Registration, (B) second, pro rata among the Selling Holders and any Other Holders who have requested participation in the Piggyback
Registration (based, for each such Selling Holder or Other Holder, on the percentage derived by dividing (1) the number of shares of Common Stock proposed to be sold by such Selling Holder or such Other Holder in such offering; by (2) the
aggregate number of shares of Common Stock proposed to be sold by all Selling Holders and all Other Holders in the Piggyback Registration other than the Persons initiating such Registration), and (C) third, to any other holder of shares of
common stock with registration rights that are subordinate to the rights of the Holders hereunder.

 Section 2.3 Secondary Underwritten Offering. 

(a) S-3 Registration. In the event that a Selling Holder or a group of Selling
Holders elects to dispose of Registrable Securities under the Shelf Registration Statement pursuant to an Underwritten Offering for its own account of at least $5.0 million (such amount, the “Minimum Commitment”), such Selling
Holder shall give notice of such election in writing (including, but not limited to, notification by e-mail; such notice, the “Selling Holder Election Notice”) to Contango not less than 20
Business Days before the date such Selling Holder intends for such Underwritten Offering to commence marketing (whether on a confidential basis or on a public basis); provided that Contango shall not be required to conduct more than one
Underwritten Offering pursuant to this Section 2.3 in any 180-day period pursuant to Selling Holder Election Notices. The Selling Holder Election Notice shall specify the number of
Registrable Securities that the Selling Holder intends to offer in such Underwritten Offering and the expected commencement date thereof. Contango shall, at the request of such Selling Holder, enter into an underwriting agreement in customary form
with the Managing Underwriter or Underwriters, which shall include, among other provisions, indemnities to the effect and to the extent provided in Section 2.8, and shall take all such other reasonable actions as are
requested by the Managing Underwriter in order to expedite or facilitate the disposition of the Registrable Securities. 

(b) Notice to Holders. Not later than two Business Days after receipt by Contango of the Selling Holder Election Notice,
unless Contango determines in accordance with Section 2.1(d) to delay such Underwritten Offering (in which event Contango shall promptly notify the initiating Selling Holder in writing of such determination), then Contango
shall provide written notice (including, but not limited to, notification by e-mail) to the other Holders of Registrable Securities of the Selling Holder’s intention to conduct an Underwritten Offering
and such notice shall offer such other Holders the opportunity to participate in such Underwritten Offering and to include in such Underwritten Offering such number of Registrable Securities as each such Holder may request in writing. Each such
other Holder will have five Business Days after notice has been delivered to request in writing submitted to Contango the inclusion of Registrable Securities in the Underwritten Offering. If no request for inclusion from a Holder is received by
Contango within the specified time, such Holder shall have no further right to participate in such Underwritten Offering. If, at any time after giving written notice of its intention to undertake an Underwritten Offering and prior to the closing of
such Underwritten Offering, the Selling Holder giving the notice shall determine for any reason not to undertake or to delay such Underwritten Offering, such Selling Holder may, at its election, give written notice of such determination to Contango
and, if the failure of such Selling Holder to participate would cause the aggregate amount of Registrable Securities participating in the Underwritten Offering to fall below the Minimum Commitment, Contango shall notify the other Holders and,
(x) in the case of a determination not to undertake such Underwritten Offering, shall be relieved of its obligation to include Registrable Securities of any other Holder, and (y) in the case of a determination to delay such Underwritten
Offering, shall be permitted to delay offering any Registrable Securities of any other Holder for the same period as the delay in the Underwritten Offering. Any other Holder shall have the right to withdraw such Holder’s request for inclusion
of such Holder’s Registrable Securities in such Underwritten Offering by giving written notice to Contango of such withdrawal 

  
 8 

 
up to and including the time of pricing of such offering. If the Managing Underwriter or Underwriters of any proposed Underwritten Offering of Registrable Securities under a Shelf Registration
Statement advises Contango that the total amount of Registrable Securities which the Selling Holders and any other Persons intend to include in such offering exceeds the number which can be sold in such offering without being likely to have a
material and adverse effect on the offering price, timing or probability of success of the distribution of the Registrable Securities offered or the market for the Registrable Securities, then the Registrable Securities to be included in such
Underwritten Offering shall include the number of Registrable Securities that such Managing Underwriter or Underwriters advises Contango can be sold without having such material and adverse effect, with such number to be allocated pro rata among the
Selling Holders and the other Holders who have requested participation in the Underwritten Offering (based, for each such Selling Holder or other Holder, on the percentage derived by dividing (A) the number of Registrable Securities proposed to
be sold by such Selling Holder or such other Holder in such offering; by (B) the aggregate number of Registrable Securities proposed to be sold by all Selling Holders and all other Holders in such Underwritten Offering). 

Section 2.4 Sale Procedures. 

(a) General Procedures. In connection with any Underwritten Offering (i) under
Section 2.2 of this Agreement, Contango shall be entitled to select the Managing Underwriter or Underwriters, and (ii) under Section 2.3 of this Agreement, the Selling Holders shall be
entitled to select the Managing Underwriter or Underwriters. In connection with an Underwritten Offering contemplated by this Agreement in which a Selling Holder participates, each Selling Holder and Contango shall be obligated to enter into an
underwriting agreement with the Managing Underwriter or Underwriters which contains such representations, covenants, indemnities and other rights and obligations as are customary in underwriting agreements for firm commitment offerings of equity
securities. No Selling Holder may participate in such Underwritten Offering unless such Selling Holder agrees to sell its Registrable Securities on the basis provided in such underwriting agreement and completes and executes all questionnaires,
powers of attorney, indemnities and other documents reasonably required under the terms of such underwriting agreement. Each Selling Holder may, at its option, require that any or all of the representations and warranties by, and the other
agreements on the part of, Contango to and for the benefit of such underwriters also be made to and for such Selling Holder’s benefit and that any or all of the conditions precedent to the obligations of such underwriters under such
underwriting agreement also be conditions precedent to its obligations. No Selling Holder shall be required to make any representations or warranties to or agreements with Contango or the underwriters other than representations, warranties or
agreements regarding such Selling Holder’s ownership of the securities being registered on its behalf and its intended method of distribution and any other representation required by law. If any Selling Holder disapproves of the terms of an
underwriting, such Selling Holder may elect to withdraw therefrom by notice to Contango and the Managing Underwriter; provided, however, that such withdrawal must be made at least one Business Day prior to the time of pricing of such
Underwritten Offering to be effective. No such withdrawal or abandonment shall affect Contango’s obligation to pay Registration Expenses. Upon the receipt by Contango of a written request from the Holders of at least $5.0 million dollars
of Registrable Securities that are participating in any Underwritten Offering contemplated by this Agreement, Contango’s management shall be required to participate in a roadshow or similar marketing effort in connection with any Underwritten
Offering. 

  
 9 

 (b) In connection with its obligations under this Article II,
Contango will, as expeditiously as possible: 
 (i) prepare and file with the Commission such amendments and
supplements to the Shelf Registration Statement and the prospectus used in connection therewith as may be necessary to keep a Shelf Registration Statement effective for the Effectiveness Period and as may be necessary to comply with the provisions
of the Securities Act with respect to the disposition of all Registrable Securities covered by a Shelf Registration Statement; 

(ii) if a prospectus supplement will be used in connection with the marketing of an Underwritten Offering from
a Shelf Registration Statement and the Managing Underwriter at any time shall notify Contango in writing that, in the sole judgment of such Managing Underwriter, the inclusion of detailed information to be used in such prospectus supplement is of
material importance to the success of the Underwritten Offering of such Registrable Securities, Contango shall use its commercially reasonable efforts to include such information in the prospectus supplement; 

(iii) furnish to each Selling Holder (A) as far in advance as reasonably practicable before filing a Shelf
Registration Statement or any other registration statement contemplated by this Agreement or any supplement or amendment thereto, upon request, copies of reasonably complete drafts of all such documents proposed to be filed (including exhibits and
each document incorporated by reference therein to the extent then required by the rules and regulations of the Commission), and provide each such Selling Holder the opportunity to object to any information pertaining to such Selling Holder and its
plan of distribution that is contained therein and make the corrections reasonably requested by such Selling Holder with respect to such information prior to filing such Shelf Registration Statement or such other registration statement and the
prospectus included therein or any supplement or amendment thereto, and (B) such number of copies of such Shelf Registration Statement or such other registration statement and the prospectus included therein and any supplements and amendments
thereto as such Persons may reasonably request in order to facilitate the public sale or other disposition of the Registrable Securities covered by such Shelf Registration Statement or other registration statement; 

(iv) if applicable, use its commercially reasonable efforts to register or qualify the Registrable Securities
covered by a Shelf Registration Statement or any other registration statement contemplated by this Agreement under the securities or blue sky laws of such jurisdictions as the Selling Holders shall reasonably request, provided that Contango will not
be required to qualify generally to transact business in any jurisdiction where it is not then required to so qualify or to take any action which would subject it to general service of process in any such jurisdiction where it is not then so
subject; 
 (v) promptly notify each Selling Holder, at any time when a prospectus relating thereto is
required to be delivered under the Securities Act, of (A) the filing of a Shelf Registration Statement or any other registration statement contemplated by this Agreement or any prospectus included therein or any amendment or supplement thereto
(other than any amendment or supplement resulting from the filing of a document 

  
 10 

 
incorporated by reference therein), and, with respect to such Shelf Registration Statement or any other registration statement or any post-effective amendment thereto, when the same has become
effective; and (B) the receipt of any written comments from the Commission with respect to any filing referred to in clause (A) and any written request by the Commission for amendments or supplements to such Shelf Registration Statement or
any other registration statement or any prospectus or prospectus supplement thereto; 
 (vi) immediately
notify each Selling Holder, at any time when a prospectus relating thereto is required to be delivered under the Securities Act, of (A) the happening of any event as a result of which the prospectus contained in a Shelf Registration Statement
or any other registration statement contemplated by this Agreement or any supplemental amendment thereto, includes an untrue statement of a material fact or omits to state any material fact required to be stated therein or necessary to make the
statements therein not misleading in the light of the circumstances then existing; (B) the issuance or threat of issuance by the Commission of any stop order suspending the effectiveness of such Shelf Registration Statement or any other
registration statement contemplated by this Agreement, or the initiation of any proceedings for that purpose; or (C) the receipt by Contango of any notification with respect to the suspension of the qualification of any Registrable Securities
for sale under the applicable securities or blue sky laws of any jurisdiction. Following the provision of such notice, Contango agrees to as promptly as practicable amend or supplement the prospectus or prospectus supplement or take other
appropriate action so that the prospectus or prospectus supplement does not include an untrue statement of a material fact or omit to state a material fact required to be stated therein or necessary to make the statements therein not misleading in
the light of the circumstances then existing and to take such other action as is necessary to remove a stop order, suspension, threat thereof or proceedings related thereto; 

(vii) upon request and subject to appropriate confidentiality obligations, furnish to each Selling Holder
copies of any and all transmittal letters or other correspondence with the Commission or any other governmental agency or self-regulatory body or other body having jurisdiction (including any domestic or foreign securities exchange) relating to such
offering of Registrable Securities; 
 (viii) in the case of an Underwritten Offering, furnish upon request a
“comfort” letter, dated the pricing date of such Underwritten Offering and a letter of like kind dated the date of the closing under the underwriting agreement, in each case, signed by the independent public accountants who have certified
Contango’s financial statements included or incorporated by reference into the applicable registration statement, and the “comfort” letter shall be in customary form and covering substantially the same matters with respect to such
registration statement (and the prospectus included therein and any supplement thereto) and as are customarily covered in accountants’ letters delivered to the underwriters in underwritten offerings of securities; 

(ix) in the case of an Underwritten Offering, use commercially reasonable efforts to furnish upon request a
letter, dated the pricing date of such Underwritten Offering and a letter of like kind dated the date of the closing under the underwriting agreement, in each case, signed by the reserve engineers who have prepared

  
 11 

 
reserve reports of estimated net proved oil and natural gas reserves with respect to certain oil and gas properties included or incorporated by reference into the applicable registration
statement, and the letter shall be in customary form and covering substantially the same matters with respect to such registration statement (and the prospectus included therein and any supplement thereto) and as are customarily covered in reserve
engineers’ letters delivered to the underwriters in underwritten offerings of securities; 
 (x) in the
case of an Underwritten Offering, use commercially reasonable efforts to furnish upon request an opinion of counsel to Contango, dated the date of the closing under the underwriting agreement, in form and substance satisfactory to the underwriters
of such Underwritten Offering; 
 (xi) otherwise use its commercially reasonable efforts to comply with all
applicable rules and regulations of the Commission and make available to its security holders, as soon as reasonably practicable, an earnings statement covering the period of at least 12 months, but not more than 18 months, beginning with
the first full calendar month after the effective date of such registration statement, which earnings statement shall satisfy the provisions of Section 11(a) of the Securities Act and Rule 158 promulgated thereunder; 

(xii) make available to the appropriate representatives of the underwriters access to such information and
Contango personnel as is reasonable and customary to enable such parties and their representatives to establish a due diligence defense under the Securities Act; provided that Contango need not disclose any
non-public information to any such representatives unless and until such representatives have entered into a confidentiality agreement with Contango; 

(xiii) cause all such Registrable Securities registered pursuant to this Agreement to be listed or quoted on
each securities exchange or nationally recognized quotation system on which similar securities issued by Contango are then listed or quoted, and cause to be satisfied all requirements and conditions of such securities exchange or nationally
recognized quotation system to the listing or quoting of such Registrable Securities that are reasonably within the control of Contango, including, without limitation, registering the Registrable Securities under the Exchange Act, if appropriate,
and using commercially reasonable efforts to cause such registration to become effective pursuant to the rule of the Commission; 

(xiv) use its commercially reasonable efforts to cause the Registrable Securities to be registered with or
approved by such other governmental agencies or authorities as may be necessary by virtue of the business and operations of Contango to enable the Selling Holders to consummate the disposition of such Registrable Securities; 

(xv) provide a transfer agent and registrar for all Registrable Securities covered by such registration
statement; and 
 (xvi) enter into customary agreements and take such other actions as are reasonably
requested by the Selling Holders in order to expedite or facilitate the disposition of such Registrable Securities. 

  
 12 

 (c) Each Selling Holder, upon receipt of notice from Contango of the
happening of any event of the kind described in Section 2.4(b)(vi), shall forthwith discontinue disposition of the Registrable Securities until such Selling Holder’s receipt of the copies of the supplemented or amended
prospectus contemplated by Section 2.4(b)(vi) or until it is advised in writing by Contango that the use of the prospectus may be resumed, and has received copies of any additional or supplemental filings incorporated by
reference in the prospectus, and, if so directed by Contango, such Selling Holder will, or will request the Managing Underwriter or underwriters, if any, to deliver to Contango (at Contango’s expense) all copies in their possession or control,
other than permanent file copies then in such Selling Holder’s possession, of the prospectus and any prospectus supplement covering such Registrable Securities current at the time of receipt of such notice. 

Section 2.5 Cooperation by Holders. Contango shall have no obligation to include Registrable Securities of a
Holder in the Shelf Registration Statement or in an Underwritten Offering under Article II of this Agreement if such Selling Holder has failed to timely furnish such information which, after consultation with its counsel, is reasonably
required in order for the registration statement or prospectus supplement, as applicable, to comply with the Securities Act. 

Section 2.6 [Reserved]. 

Section 2.7 Expenses. 

(a) Certain Definitions. “Registration Expenses” means all expenses incident to Contango’s
performance under or compliance with this Agreement to effect the registration of Registrable Securities in a Shelf Registration Statement pursuant to Section 2.1, a Piggyback Registration pursuant to
Section 2.2, or an Underwritten Offering pursuant to Section 2.3 and the disposition of such securities, including, without limitation, all registration, filing, securities exchange listing and
fees, all registration, filing, qualification and other fees and expenses of complying with securities or blue sky laws, fees of the Financial Industry Regulatory Authority, transfer taxes and fees of transfer agents and registrars, all word
processing, duplicating and printing expenses, all roadshow expenses borne by it and the fees and disbursements of independent public accountants and counsel for Contango, including the expenses of any special audits or “comfort” letters
required by or incident to such performance and compliance. Except as otherwise provided in Section 2.8 hereof, Contango shall not be responsible for legal fees incurred by Holders in connection with the exercise of such
Holders’ rights hereunder. In addition, Contango shall not be responsible for any “Selling Expenses,” which means all underwriting fees, discounts and selling commissions and transfer taxes allocable to the sale of the
Registrable Securities. 
 (b) Expenses. Contango will pay all reasonable Registration Expenses in connection with a
Shelf Registration Statement, Piggyback Registration or Underwritten Offering, whether or not any sale is made pursuant to such Shelf Registration Statement, Piggyback Registration or Underwritten Offering. Each Selling Holder shall pay its pro rata
share of all Selling Expenses in connection with any sale of its Registrable Securities hereunder. 

  
 13 

 Section 2.8 Indemnification. 

(a) By Contango. In the event of a registration of any Registrable Securities under the Securities Act pursuant to this
Agreement, to the extent permitted by applicable law, Contango will indemnify and hold harmless each Selling Holder thereunder, its directors, officers, partners, members, employees, investment advisers, agents, representatives and managers, and
each other Person, if any, who controls such Selling Holder, within the meaning of the Securities Act and the Exchange Act, and the directors, officers, partners, members, employees, investment advisers, agents, representatives and managers of such
controlling Person, against any losses, claims, damages, expenses or liabilities (including reasonable attorneys’ fees and expenses), including any of the foregoing incurred in settlement of any litigation commenced or threatened by any party
other than a Selling Holder (collectively, “Losses”), joint or several, to which such Selling Holder or controlling Person or directors, officers, employees, agents, representatives or managers may become subject under the
Securities Act, the Exchange Act or otherwise, insofar as such Losses (or actions or proceedings, whether commenced or threatened, in respect thereof) arise out of or are based upon any untrue statement or alleged untrue statement of any material
fact (in the case of any prospectus, in light of the circumstances under which such statement is made) contained in the Shelf Registration Statement or any other registration statement contemplated by this Agreement, any preliminary prospectus or
final prospectus contained therein, or any free writing prospectus related thereto, or any amendment or supplement thereof, or arise out of or are based upon the omission or alleged omission to state therein a material fact required to be stated
therein or necessary to make the statements therein (in the case of a prospectus, in light of the circumstances under which they were made) not misleading, and will reimburse each such Selling Holder, its directors and officers, and each such
controlling Person and each such director, officer, employee, agent, representatives or manager for any legal or other expenses reasonably incurred by them in connection with investigating or defending any such Loss or actions or proceedings;
provided, however, that Contango will not be liable in any such case if and to the extent that any such Loss arises out of or is based upon an untrue statement or alleged untrue statement or omission or alleged omission so made in
conformity with information furnished by such Selling Holder or such controlling Person in writing specifically for use in the Shelf Registration Statement or such other registration statement, or prospectus supplement, as applicable. Such indemnity
shall remain in full force and effect regardless of any investigation made by or on behalf of such Selling Holder or any such director, officer, partner, member, employee, investment adviser, agent, representatives, manager or controlling Person,
and shall survive the transfer of such securities by such Selling Holder. 
 (b) By Each Selling Holder. Each Selling
Holder agrees severally and not jointly to indemnify and hold harmless Contango, its directors, officers, employees, representatives and agents and each Person, if any, who controls Contango within the meaning of the Securities Act or of the
Exchange Act to the same extent as the foregoing indemnity from Contango to the Selling Holders, but only with respect to information regarding such Selling Holder furnished in writing by or on behalf of such Selling Holder expressly for inclusion
in the Shelf Registration Statement or prospectus supplement relating to the Registrable Securities, or any amendment or supplement thereto. The maximum liability of each Selling Holder for any such indemnification shall not exceed the amount of net
proceeds received by such seller from the sale of such Selling Holder’s Registrable Securities. 

  
 14 

 (c) Notice. Promptly after receipt by an indemnified party hereunder
of notice of the commencement of any action, such indemnified party shall, if a claim in respect thereof is to be made against the indemnifying party hereunder, notify the indemnifying party in writing thereof, but the omission so to notify the
indemnifying party shall not relieve it from any liability which it may have to any indemnified party other than under this Section 2.8(c) except to the extent that the indemnifying party is materially prejudiced by such
failure. In any action brought against any indemnified party, it shall notify the indemnifying party of the commencement thereof. The indemnifying party shall be entitled to participate in and, to the extent it shall wish, to assume and undertake
the defense thereof with counsel reasonably satisfactory to such indemnified party and, after notice from the indemnifying party to such indemnified party of its election so to assume and undertake the defense thereof, the indemnifying party shall
not be liable to such indemnified party under this Section 2.8 for any legal expenses subsequently incurred by such indemnified party in connection with the defense thereof other than reasonable costs of investigation and
of liaison with counsel so selected; provided, however, that, (i) if the indemnifying party has failed to assume the defense and employ counsel reasonably satisfactory to the indemnified party or (ii) if the defendants in any
such action include both the indemnified party and the indemnifying party and counsel to the indemnified party shall have concluded that there may be reasonable defenses available to the indemnified party that are different from or additional to
those available to the indemnifying party, or if the interests of the indemnified party reasonably may be deemed to conflict with the interests of the indemnifying party or representation by both parties by the same counsel is otherwise
inappropriate under the applicable standards of professional conduct, then the indemnified party shall have the right to select a separate counsel and to assume such legal defense and otherwise to participate in the defense of such action, with the
reasonable expenses and fees of such separate counsel and other reasonable expenses related to such participation to be reimbursed by the indemnifying party as incurred. Notwithstanding any other provision of this Agreement, the indemnifying party
shall not settle any indemnified claim without the consent of the indemnified party, unless the settlement thereof imposes no liability or obligation on, includes a complete release from liability of, and does not contain any admission of wrong
doing by, the indemnified party. 
 (d) Contribution. If the indemnification provided for in this
Section 2.8 is held by a court or government agency of competent jurisdiction to be unavailable to Contango or any Selling Holder or is insufficient to hold them harmless in respect of any Losses, then each such
indemnifying party, in lieu of indemnifying such indemnified party, shall contribute to the amount paid or payable by such indemnified party as a result of such Losses in such proportion as is appropriate to reflect the relative fault of Contango on
the one hand and of such Selling Holder on the other in connection with the statements or omissions which resulted in such Losses, as well as any other relevant equitable considerations; provided, however, that in no event shall such
Selling Holder be required to contribute an aggregate amount in excess of the dollar amount of proceeds (net of Selling Expenses) received by such Selling Holder from the sale of Registrable Securities giving rise to such indemnification less the
amount of any damages that such Selling Holder has otherwise been required to pay by reason of such untrue or alleged untrue statement or omission or alleged omission. The relative fault of Contango on the one hand and each Selling Holder on the
other shall be determined by reference to, among other things, whether the untrue or alleged untrue statement of a material fact or the omission or alleged omission to state a material fact has been made by, or relates to, information supplied by
such party, and the parties’ relative intent, knowledge, access to information and opportunity to correct or prevent such statement or omission. The parties hereto agree that it would not be just and equitable if contributions pursuant to this
paragraph were to be determined by pro rata allocation or by any other method of allocation which 

  
 15 

 
does not take account of the equitable considerations referred to in the first sentence of this paragraph. The amount paid by an indemnified party as a result of the Losses referred to in the
first sentence of this paragraph shall be deemed to include any legal and other expenses reasonably incurred by such indemnified party in connection with investigating or defending any Loss which is the subject of this paragraph. No person guilty of
fraudulent misrepresentation (within the meaning of Section 11(f) of the Securities Act) shall be entitled to contribution from any Person who is not guilty of such fraudulent misrepresentation. 

(e) Other Indemnification. The provisions of this Section 2.8 shall be in addition to any
other rights to indemnification or contribution which an indemnified party may have pursuant to law, equity, contract or otherwise. 

Section 2.9 Rule 144 Reporting. With a view to making available the benefits of certain rules and regulations of
the Commission that may permit the sale of the Registrable Securities to the public without registration, Contango agrees to use its commercially reasonable efforts to: 

(a) Make and keep public information regarding Contango available, as those terms are understood and defined in Rule 144; 

(b) File with the Commission in a timely manner all reports and other documents required of Contango under the Securities Act
and the Exchange Act; and 
 (c) So long as a Holder, together with its Affiliates, owns any Registrable Securities,
(i) unless otherwise available at no charge by access electronically to the Commission’s EDGAR filing system (or any successor system), furnish to such Holder forthwith upon request a copy of the most recent annual or quarterly report of
Contango, and such other reports and documents so filed as such Holder may reasonably request in availing itself of any rule or regulation of the Commission allowing such Holder to sell any such securities without registration and (ii) to the
extent accurate, furnish to such Holder upon reasonable request a written statement of Contango that it has complied with the reporting requirements of Rule 144. 

Section 2.10 Transfer or Assignment of Registration Rights. The rights to cause Contango to register Registrable
Securities granted to the Purchasers by Contango under this Article II may be transferred or assigned by any Purchaser to one or more transferees or assignees of Registrable Securities; provided, however, that
(a) unless the transferee or assignee is an Affiliate of, and after such transfer or assignment continues to be an Affiliate of, such Purchaser, the amount of Registrable Securities transferred or assigned to such transferee or assignee shall
represent at least $2.5 million of Registrable Securities (based on the Common Stock Price) or, if less, 100% of the Registrable Securities then held by such Purchaser, (b) Contango is given written notice prior to any said transfer or
assignment, stating the name and address of each such transferee or assignee and identifying the securities with respect to which such registration rights are being transferred or assigned, and (c) each such transferee or assignee assumes in
writing responsibility for its portion of the obligations of such Purchaser under this Agreement. 

  
 16 

 Section 2.11 Aggregation of Registrable Securities. (a) All
Registrable Securities held or acquired by Persons who are Affiliates of one another shall be aggregated together for the purpose of determining the availability of any rights under this Agreement. 

(b) All other shares of Common Stock held by a Person and for which such Person has similar registration rights pursuant to an
agreement between such Person and Contango shall be aggregated together for the purpose of determining such Person’s rights under this Agreement solely as such shares relate to minimum quantity requirements contemplated herein; provided that,
for the avoidance of doubt, such Common Stock shall not otherwise be deemed Registrable Securities for any other purpose under this Agreement.

resolution remains in full force and effect on the date hereof: 
 RESOLVED, that the rights, powers and preferences, and
the qualifications, limitations and restrictions, of the Series C Contingent Convertible Preferred Stock as set forth in the Statement of Resolution are hereby approved and adopted by the Board and the Series C Contingent Convertible Preferred Stock
is hereby authorized out of the Corporation’s authorized preferred stock, par value $0.04 per share; and the form, terms and provisions of the Statement of Resolution are hereby approved, adopted, ratified and confirmed in all respects as
follows: 
 Section 1. Designation and Amount; Ranking. 

(a) The shares of such series shall be designated the “Series C Contingent Convertible Preferred Stock” (the

 (b) Each share of Series C Preferred Stock shall be identical in all
respects with the other shares of Series C Preferred Stock. 
 (c) The authorized number of shares of Series C Preferred
Stock shall initially be 2,700,000, which number may from time to time be increased or decreased by resolution of the Board as permitted by the Code. The initial shares of Series C Preferred Stock shall be issued and sold by the Corporation pursuant

(a) Holders of shares of Series C Preferred Stock shall be entitled to receive, when and as declared by the Board and declared
by the Corporation, out of funds that are legally available therefor, cash dividends of ten percent (10%) of the Original Issue Price per annum on each outstanding share of Series C Preferred Stock. Such dividends shall accrue from the first
anniversary of the Original Issue Date of the Series C Preferred Stock and shall cease to accrue on the date immediately preceding the date on which the Conversion Requirements described in Section 8 are satisfied. The
“Original Issue Price” means $2.50 per share (as adjusted for any stock split, combination or similar event or transaction directly affecting the Series C Preferred Stock but not by any accrued dividends). The
“Original Issue Date” means December 23, 2019. 
 (b) Following the first anniversary of the
Original Issue Date, dividends pursuant to this Section 3 shall be payable quarterly in cash, on March 31, June 30, September 30 and December 31 of each year, beginning December 31, 2020, when, as
and if declared by the Board, until the time at which the Conversion Requirements are satisfied; provided, however, that when the Series C Preferred Stock is no longer outstanding, no dividends shall be payable to the holders of the
Series C Preferred Stock or the holders of the Common Stock into which the Series C Preferred Stock converts. Payments of any dividends pursuant to this Section 3 shall be payable only if the Corporation has surplus income
and such payment is permissible under the Corporation’s debt instruments then in effect. 
 (c) No dividends or
distributions shall be paid with respect to the Common Stock (i) prior to the holders of the Series C Preferred Stock having received all accrued but unpaid dividends on the Series C Preferred Stock or (ii) unless and until all shares of
Series C Preferred Stock have been converted to shares of Common Stock. 
 (d) Holders of Series C Preferred Stock shall
fully participate, on an as-converted basis, in any dividends declared and paid or distributions on Common Stock as if the Series C Preferred Stock were converted into shares of Common Stock as of the record
date for such dividend or distribution at the Conversion Ratio. 
 Section 4. Liquidation. 

(a) Prior to conversion pursuant to Section 8, in the event of a liquidation (complete or partial),
dissolution or winding up of the affairs of the Corporation, whether voluntary or involuntary (a “Liquidation”), after payment or provision for payment of the debts and other liabilities of the Corporation, the holders of
Series C Preferred Stock shall be entitled to receive, in respect of any shares of Series C Preferred Stock held by them, out of assets of the Corporation available for distribution to shareholders of the Corporation or their assignees, and subject
to the 

  
 3 

 
rights of any outstanding shares of Senior Stock and before any amount shall be distributed to the holders of Junior Stock, a liquidating distribution (the “Liquidation
Distribution”) in an amount equal to the amount such holder of Series C Preferred Stock would have been entitled to receive had such holder converted its shares of Series C Preferred Stock into shares of Common Stock at the Conversion
Ratio immediately prior to such Liquidation. 
 (b) If, upon any Liquidation, the amount payable with respect to the
Liquidation Distribution is not paid in full, the holders of the Series C Preferred Stock and any Parity Stock shall share equally and ratably in any distribution of the Corporation’s assets in proportion to the respective liquidation
distributions to which they are entitled. 
 (c) After the payment in cash or proceeds to the holders of shares of the Series
C Preferred Stock of the full amount of the Liquidation Distribution with respect to outstanding shares of Series C Preferred Stock, the holders of outstanding shares of Series C Preferred Stock shall have no right or claim, based on their ownership
of shares of Series C Preferred Stock, to the remaining assets of the Corporation, if any. Whenever any such distribution shall be paid in property other than cash, the value of such distribution shall be the fair market value of such property as
determined in the good faith reasonable discretion of the Board or liquidating trustee, as the case may be. 
 Section 5.
Voting. 
 Except as set forth herein or as otherwise required by the Code or other applicable law,
the holders of shares of Series C Preferred Stock shall have no voting rights and their consent shall not be required for taking any corporate action. 

Section 6. Reservation of Common Stock. 

(a) Subject to the Conversion Requirements set forth in Section 8, at any time that any Series C
Preferred Stock is outstanding, the Corporation shall from time to time take all lawful action within its control to cause the authorized capital stock of the Corporation to include a number of authorized but unissued shares of Common Stock equal to
2,700,000 shares (for the avoidance of doubt, taking into account any other obligations of the Corporation to reserve Common Stock upon the conversion, exchange or exercise of other securities of the Corporation such that any other reservation may
not be counted toward the reservation of Common Stock hereunder) (such authorized but unissued shares, the “Reserved Shares”). If, at any time, the Corporation lacks a sufficient number of Reserved Shares, the Corporation
shall use its reasonable best efforts to take all lawful action within its control to effect an amendment to the Certificate of Formation to increase the authorized but unissued shares of Common Stock of the Corporation to provide for a sufficient
number of Reserved Shares. 
 (b) If any shares of Common Stock to be reserved for the purpose of conversion of the Series C
Preferred Stock require registration or listing with or approval of any governmental authority, stock exchange or other regulatory body under any federal or state law or regulation or otherwise before such shares may be validly issued or delivered
upon conversion, the Corporation shall, at its sole cost and expense, in good faith and as expeditiously as possible following satisfaction of the Conversion Requirements set forth in Section 8, endeavor to secure such
registration, listing or approval, as the case may be. 

  
 4 

 Section 7. Form. 

(a) Notwithstanding anything to the contrary herein, the shares of Series C Preferred Stock and any shares of Common Stock
issued upon conversion thereof shall be in uncertificated, book-entry form or, if requested by any holder of the Series C Preferred Stock, such holder’s shares may be issued in certificated form, in each case as permitted by the Bylaws of the
Corporation and the Code, and shall bear a legend in substantially the following form: 
 “THE SECURITIES REPRESENTED
HEREBY HAVE NOT BEEN REGISTERED UNDER THE SECURITIES ACT OF 1933, AS AMENDED (THE “SECURITIES ACT”), OR ANY STATE SECURITIES LAWS. THESE SECURITIES MAY NOT BE REOFFERED, SOLD, ASSIGNED, TRANSFERRED, PLEDGED, ENCUMBERED OR OTHERWISE
DISPOSED OF IN THE ABSENCE OF SUCH REGISTRATION OR UNLESS SUCH TRANSACTION IS EXEMPT FROM, OR NOT SUBJECT TO, REGISTRATION.” 

(b) The duly appointed transfer agent for the Series C Preferred Stock shall be Continental Stock Transfer & Trust
Company (the “Transfer Agent”). The Corporation may, in its sole discretion, remove the Transfer Agent in accordance with the agreement between the Corporation and the Transfer Agent; provided, that if the Corporation
removes Continental Stock Transfer & Trust Company, the Corporation shall appoint a successor transfer agent who shall accept such appointment prior to the effectiveness of such removal. 

(c) Transfers of Series C Preferred Stock or any shares of Common Stock issued upon conversion thereof shall be made only upon
receipt of proper transfer instructions and, if applicable, the surrender of the certificate representing such shares (or, if such registered holder alleges that such certificate has been lost, stolen or destroyed, a lost certificate affidavit and
agreement reasonably acceptable to the Corporation to indemnify the Corporation against any claim that may be made against the Corporation on account of the alleged loss, theft or destruction of such certificate), from the registered owner or from a
duly authorized attorney or from an individual presenting proper evidence of succession, assignment or authority to transfer the stock. The Corporation may refuse any requested transfer until furnished evidence satisfactory to it that such transfer
is proper. 
 Section 8. Conversion. 

(a) Following the approval by the shareholders of the Corporation, in accordance with applicable law and the applicable rules
and regulations of the principal national securities exchange on which the Common Stock is listed for trading (the “National Securities Exchange”), of the issuance of the shares of Common Stock to be issued upon conversion of
the Series C Preferred Stock pursuant to this Section 8 (the “Conversion Requirements”), each share of Series C Preferred Stock shall automatically convert into one share of Common Stock (the
“Conversion Ratio”). 

  
 5 

 (b) Any Common Stock delivered as a result of conversion pursuant to this
Section 8 following satisfaction of the Conversion Requirements shall be validly issued, fully paid and non- assessable, free and clear of any preemptive right, liens, claims, rights
or encumbrances other than those arising under the Code or the Bylaws of the Corporation. Immediately following the settlement of conversion, the rights of the holders of converted Series C Preferred Stock shall cease and the persons entitled to
receive shares of Common Stock upon the conversion of shares of Series C Preferred Stock shall be treated for all purposes as having become the owners of such shares of Common Stock. Concurrently with such conversion, the converted shares of Series
C Preferred Stock shall cease to be outstanding and shall be canceled, and the shares of Series C Preferred Stock formerly designated pursuant to this Statement of Resolution shall be restored to authorized but unissued shares of Series C Preferred
Stock. 
 (c) If, after the Original Issue Date, the Corporation (i) makes a distribution on its Common Stock in cash,
securities (including Common Stock) or other property or assets, (ii) subdivides or splits its outstanding Common Stock into a greater number of Common Stock, (iii) combines or reclassifies its Common Stock into a smaller number of Common
Stock or (iv) issues by reclassification of its Common Stock any securities (including any reclassification in connection with a merger, consolidation or business combination in which the Corporation is the surviving person), then the
Conversion Ratio in effect at the time of the record date for such distribution or of the effective date of such subdivision, split, combination, or reclassification shall be proportionately adjusted so that the conversion of the Series C Preferred
Stock after such time shall entitle the holder to receive the aggregate number of Common Stock (or shares of any securities into which such shares of Common Stock would have been combined, consolidated, merged or reclassified pursuant to clauses
(iii) and (iv) above) that such holder would have been entitled to receive if the Series C Preferred Stock had been converted into Common Stock immediately prior to such record date or effective date, as the case may be, and in the case of a
merger, consolidation or business combination in which the Corporation is the surviving person, the Corporation shall provide effective provisions to ensure that the provisions in this Statement of Resolution relating to the Series C Preferred Stock
shall not be abridged or amended and that the Series C Preferred Stock shall thereafter retain the same powers, preferences and relative participating, optional and other special rights, and the qualifications, limitations and restrictions thereon,
that the Series C Preferred Stock had immediately prior to such transaction or event. An adjustment made pursuant to this Section 8(c) shall become effective immediately after the record date in the case of a distribution
and shall become effective immediately after the effective date in the case of a subdivision, combination, reclassification (including any reclassification in connection with a merger, consolidation or business combination in which the Corporation
is the surviving person) or split. Such adjustment shall be made successively whenever any event described above shall occur. 

(d) Notwithstanding any of the other provisions of this Section 8, no adjustment shall be made to the
Conversion Ratio pursuant to Section 8(c) as a result of any of the following: 
 (i) the grant of
Common Stock or options, warrants or rights to purchase Common Stock to employees, officers or directors of the Corporation or its subsidiaries, under compensation plans and agreements approved in good faith by the Board; provided, that in
the case of options, warrants or rights to purchase Common Stock, the exercise price per Common Stock shall not be less than the closing price of the Common Stock (as reported by the National Securities Exchange) on the date such option, warrant or
other right is issued; 

  
 6 

 (ii) the issuance of any Common Stock as all or part of the consideration to
effect (A) the closing of any acquisition by the Corporation of assets of a third party or (B) the consummation of a merger, consolidation or other business combination of the Corporation with another entity in which the Corporation
survives and the Common Stock remain outstanding to the extent such transaction(s) is or are validly approved by the vote or consent of the Board; 

(iii) without duplication of Section 8(d)(i) above, the issuance of options, warrants or other rights
to purchase Common Stock, or securities exercisable or convertible into or exchangeable for Common Stock (or options, warrants or other rights to purchase any such securities that are exercisable or convertible into or exchangeable for Common Stock,
in each case, that are outstanding on the date of first issuance of shares of Series C Preferred Stock); and 
 (iv) the
issuance of securities for which an adjustment is made under another provision of this Section 8. 

(e) The Corporation shall pay any and all issue, documentary, stamp and other taxes, excluding any income, franchise, property
or similar taxes, that may be payable in respect of any issue or delivery of Common Stock on conversion of Series C Preferred Stock pursuant hereto. However, the holder of any Series C Preferred Stock shall pay any tax that is due because Common
Stock issuable upon conversion thereof is issued in a name other than such holder’s name. 
 (f) No fractional Common
Stock shall be issued upon the conversion of any Series C Preferred Stock. All Common Stock (including fractions thereof) issuable upon conversion of more than one share of Series C Preferred Stock by a holder thereof shall be aggregated for
purposes of determining whether the conversion would result in the issuance of any fractional stock. If, after the aforementioned aggregation, the conversion would result in the issuance of a fraction of a Common Stock, the Corporation shall not
issue a fractional Common Stock but shall round the fractional Common Stock to the nearest whole Common Stock (and a 0.5 of a share of Common Stock shall be rounded up to the next higher share of Common Stock). 

Section 9. Additional Procedures. 

(a) In connection with any conversion pursuant to Section 8, the holder of Series C Preferred Stock
must deliver transfer instruments reasonably satisfactory to the Corporation, at the principal office of the Corporation (or such other place mutually acceptable to the holder of Series C Preferred Stock and the Corporation), in accordance with
Section 7(c). 
 (b) On the date of conversion pursuant to Section 8, the
number of shares of Common Stock into which the applicable shares of Series C Preferred Stock are converted shall be promptly issued in uncertificated, book-entry form and evidence thereof shall be delivered or, if requested by any holder of the
Series C Preferred Stock, such shares of Common Stock may be issued in certificated form and such certificates shall be delivered, to the holder of Series C Preferred Stock thereof or such holder’s designee upon the furnishing of appropriate
endorsements and transfer documents and the payment of all transfer and similar taxes, if any, allocable to such holder. 

  
 7 

 Section 10. No Other Rights. 

The shares of Series C Preferred Stock shall not have any powers, designations, preferences or relative, participating,
optional, or other special rights, nor shall there be any qualifications, limitations or restrictions or any powers, designations, preferences or rights of such shares, other than as set forth herein or in the Certificate of Formation, or as may be
provided by law. 
 Section 11. Other Provisions. 

(a) The shares of Series C Preferred Stock shall not be subject to the operation of any retirement or sinking fund. 

(b) In case any one or more of the provisions contained in this Statement of Resolution shall be invalid, illegal or
unenforceable in any respect, the validity, legality and enforceability of the remaining provisions contained herein shall not in any way be affected or impaired thereby. Furthermore, in lieu of any such invalid, illegal or unenforceable provision,
there shall be added automatically as a part of this Statement of Resolution a provision as similar in terms to such invalid, illegal or unenforceable provision as may be possible and be legal, valid and enforceable, unless the requisite parties
separately agree to a replacement provision that is valid, legal and enforceable. 
 (c) Any amendment, modification, waiver
or alteration of, or supplement to, this Statement of Resolution shall require approval of a majority of the members of the Board not affiliated with any beneficial owner of the Series C Preferred Stock. 

(d) Any payments, issuances or distributions required to be made hereunder on any day that is not a Business Day shall be made
on the next succeeding Business Day without interest or additional payment for such delay. For the purposes of this Statement of Resolution, “Business Day” shall mean each day that is not a Saturday, Sunday or other day on
which banking institutions in Houston, Texas are authorized or required by law to close. All payments required hereunder shall be made by wire transfer of immediately available funds in United States Dollars to the holders in accordance with the
payment instructions as such holders may deliver by written notice to the Corporation from time to time. 
 Section 12. Effective
Date. 
 This Statement of Resolution shall become effective on December 23, 2019.
