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.

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

11

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 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.

STATEMENT OF RESOLUTION

ESTABLISHING SERIES OF SHARES

DESIGNATED

SERIES A CONTINGENT CONVERTIBLE PREFERRED STOCK

OF CONTANGO OIL & GAS COMPANY

Pursuant to Section 21.155 and Section 21.156 of the Texas Business Organizations Code (the “Code”):

CONTANGO OIL & GAS COMPANY, a Texas corporation (the “Corporation”), certifies that pursuant to the authority contained in Article IV of its Amended and Restated Certificate of Formation (the “Certificate of Formation”), and in accordance with the provisions of Section 21.155 and Section 21.156 of the Code, the Board of Directors of the Corporation (the “Board”) duly approved and adopted on September 9, 2019, and a duly authorized Pricing Committee of the Board has duly approved and adopted on September 12, 2019, the following resolution creating and providing for the establishment and issuance of a series of shares of Series A Preferred Stock (defined below) as hereinafter described, providing for the designations, preferences, limitations and relative rights, voting, redemption and other rights thereof and the qualifications, limitations or restrictions thereof, in addition to those set forth in the Certificate of Formation, all in accordance with the provisions of Section 21.155 and Section 21.156 of the Code, which 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 A Contingent Convertible Preferred Stock as set forth in the Statement of Resolution are hereby approved and adopted by the Board and the Series A 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 A Contingent Convertible Preferred Stock” (the “Series A Preferred Stock”).

(b) Each share of Series A Preferred Stock shall be identical in all respects with the other shares of Series A Preferred Stock.

(c) The authorized number of shares of Series A Preferred Stock shall initially be 789,474, which number may from time to time be increased or decreased by resolution of the Board as permitted by the Code.

(d) For purposes of this Statement of Resolution, “Capital Stock” of any person means any and all shares, interests, participations or other equivalents however designated of corporate stock or other equity participations, including partnership interests, whether general or limited, of such person and any rights (other than debt securities convertible or exchangeable into an equity interest), warrants or options to acquire an equity interest in such person. The Series A Preferred Stock shall, with respect to dividend rights and rights upon a liquidation, winding-up or dissolution of the Corporation, rank:

(i) senior to any class or series of Capital Stock of the Corporation, the terms of which do not expressly provide that such class or series ranks senior to or on a parity with the Series A Preferred Stock with respect to dividend rights or rights upon a liquidation, winding-up or dissolution of the Corporation (collectively, together with any warrants, rights, calls or options exercisable for or convertible into such Capital Stock, the “Junior Stock”);

(ii) on parity with the Common Stock, par value $0.04 per share, of the Corporation (“Common Stock”) and any class or series of Capital Stock of the Corporation, the terms of which provide that such class or series ranks on a parity with the Series A Preferred Stock with respect to dividend rights or rights upon a liquidation, winding-up or dissolution of the Corporation (collectively, together with any warrants, rights, calls or options exercisable for or convertible into such Capital Stock, the “Parity Stock”); and

(iii) junior to any class or series of Capital Stock of the Corporation (other than Common Stock), the terms of which expressly provide that such class or series ranks senior to the Series A Preferred Stock with respect to dividend rights or rights upon a liquidation, winding-up or dissolution of the Corporation (collectively, together with any warrants, rights, calls or options exercisable for or convertible into such Capital Stock, the “Senior Stock”).

2

Section 3. Dividends.

(a) Holders of shares of Series A 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 A Preferred Stock. Such dividends shall accrue from the first anniversary of the Original Issue Date of the Series A 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 $9.50 per share (as adjusted for any stock split, combination or similar event or transaction directly affecting the Series A Preferred Stock but not by any accrued dividends). The “Original Issue Date” means September 17, 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 September 30, 2020, when, as and if declared by the Board, until the time at which the Conversion Requirements are satisfied; provided, however, that when the Preferred Stock is no longer outstanding, no dividends shall be payable to the holders of the Series A Preferred Stock or the holders of the Common Stock into which the Series A 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 A Preferred Stock having received all accrued but unpaid dividends on the Series A Preferred Stock or (ii) unless and until all shares of Series A Preferred Stock have been converted to shares of Common Stock.

(d) Holders of Series A 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 A 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 A Preferred Stock shall be entitled to receive, in respect of any shares of Series A 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 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 A Preferred Stock would have been entitled to receive had such holder converted its shares of Series A Preferred Stock into shares of Common Stock at the Conversion Ratio immediately prior to such Liquidation.

3

(b) If, upon any Liquidation, the amount payable with respect to the Liquidation Distribution is not paid in full, the holders of the Series A 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 A Preferred Stock of the full amount of the Liquidation Distribution with respect to outstanding shares of Series A Preferred Stock, the holders of outstanding shares of Series A Preferred Stock shall have no right or claim, based on their ownership of shares of Series A 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.

The holders of outstanding shares of Series A Preferred Stock shall have the following voting rights:

(a) Each share of Series A Preferred Stock shall entitle the holder thereof to voting power equal to 8.71 shares of Common Stock on all matters submitted to a vote of the shareholders of the Corporation; provided that, to eliminate fractional votes, the votes cast by the shares of Series A Preferred Stock in the aggregate “for” or “against” a matter will be rounded down to the nearest whole vote.

(b) In the event the Corporation shall at any time after declare or pay any dividend on the Common Stock payable in shares of Common Stock, or effect a subdivision, combination or consolidation of the outstanding shares of Common Stock, then in each such case the number of votes per share to which holders of shares of Series A Preferred Stock were entitled immediately prior to such event shall be adjusted by multiplying such number by a fraction, the numerator of which is the number of shares of Common Stock outstanding immediately after such event and the denominator of which is the number of shares of Common Stock that were outstanding immediately prior to such event.

(c) Except as otherwise provided herein or by the Code or other applicable law, the holders of shares of Series A Preferred Stock and the holders of shares of Common Stock shall vote together as one class on all matters submitted to a vote of the shareholders of the Corporation.

(d) Except as set forth herein or as otherwise required by the Code or other applicable law, the holders of shares of Series A Preferred Stock shall have no special voting rights and their consent shall not be required (except to the extent they are entitled to vote with the holders of shares of Common Stock as set forth herein) for taking any corporate action.

4

Section 6. Reservation of Common Stock.

(a) Subject to the Conversion Requirements set forth in Section 8, at any time that any Series A 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 7,894,740 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 A 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.

Section 7. Form.

(a) Notwithstanding anything to the contrary herein, the shares of Series A Preferred Stock and any shares of Common Stock issued upon conversion thereof shall be in uncertificated, book-entry form 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 A 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 A Preferred Stock or any shares of Common Stock issued upon conversion thereof held in uncertificated, book-entry form shall be made only upon the transfer books of the Corporation kept at an office of the Transfer Agent upon receipt of proper transfer instructions from the registered owner of such uncertificated shares, 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.

5

Section 8. Conversion.

(a) Following (i) effectiveness of an amendment to the Certificate of Formation to increase the number of authorized shares of Common Stock by at least 50,000,000 shares and (ii) 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 then listed for trading (the “National Securities Exchange”), of the issuance of the shares of Common Stock to be issued upon conversion of the Preferred Stock pursuant to this Section 8 (the “Conversion Requirements”), each share of Series A Preferred Stock shall automatically convert into 10 shares of Common Stock (the “Conversion Ratio”).

(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 A Preferred Stock shall cease and the persons entitled to receive shares of Common Stock upon the conversion of shares of Series A 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 A Preferred Stock shall cease to be outstanding, shall be canceled and the shares of Series A Preferred Stock formerly designated pursuant to this Statement of Resolution shall be restored to authorized but unissued shares of 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 A 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 A 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 A Preferred Stock shall not be abridged or amended and that the Series A 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 A 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.

6

(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;

(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 A 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 A Preferred Stock pursuant hereto. However, the holder of any Series A Preferred Stock shall pay any tax that is due because Common Stock issuable upon conversion thereof are issued in a name other than such holder’s name.

(f) No fractional Common Stock shall be issued upon the conversion of any Series A Preferred Stock. All Common Stock (including fractions thereof) issuable upon conversion of more than one share of Series A 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).

7

Section 9. Additional Procedures.

(a) In connection with any conversion pursuant to Section 8, the holder of Series A 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 A 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 A Preferred Stock are converted shall be promptly issued in uncertificated, book-entry form and evidence thereof shall be delivered to the holder of Series A 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.

Section 10. No Other Rights.

The shares of Series A 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 A 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 John C. Goff.

(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 September 17, 2019.

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 conversion of the Preferred Stock. Contango shall use its commercially reasonable efforts to cause such initial Shelf Registration Statement to become effective no later than 120 days from its initial filing. 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 (i) 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, (ii) there are no longer any Registrable Securities outstanding and (iii) three years from the Effective Date (the “Effectiveness Period”). A Shelf Registration Statement filed pursuant to this Section 2.l(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 five Business Days of such date, Contango shall provide the Holders with written notice of the effectiveness of a Shelf Registration Statement.

3

(b) 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.

(c) 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 60 consecutive days or an aggregate of 180 days in any 365-day period. Upon disclosure of such information or the termination of the condition described above, Contango shall provide prompt notice 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 Sale Procedures.

(a) 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) 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

4

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;

(iii) 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;

(iv) 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;

(v) 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;

5

(vi) 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;

(vii) 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;

(viii) 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;

(ix) provide a transfer agent and registrar for all Registrable Securities covered by such registration statement; and

(x) 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.

(b) Each Selling Holder, upon receipt of notice from Contango of the happening of any event of the kind described in Section 2.2(b)(v), 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 2.2(b)(v) 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 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 2.3 Cooperation by Holders. Contango shall have no obligation to include Registrable Securities of a Holder in the Shelf Registration Statement if such Selling Holder has failed to timely furnish such information which, in the opinion of counsel to Contango, is reasonably required in order for the registration statement or prospectus supplement, as applicable, to comply with the Securities Act.

6

Section 2.4 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 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, and the fees and disbursements of Contango’s independent public accountants and counsel for Contango. Except as otherwise provided in Section 2.5 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, transfer taxes and fees of counsel allocable to the sale of the Registrable Securities.

(b) Expenses. Contango will pay all reasonable Registration Expenses in connection with a Shelf Registration Statement, whether or not any sale is made pursuant to such Shelf Registration Statement.

Section 2.5 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, employees, agents, representatives and managers, and each Person, if any, who controls such Selling Holder within the meaning of the Securities Act and the Exchange Act, and its directors, officers, employees, agents, representatives and managers, 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

7

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, employee, 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.

(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 2.5(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 2.5 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.

8

(d) Contribution. If the indemnification provided for in this Section 2.5 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 2.5 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 2.6 Transfer or Assignment of Registration Rights. Except as otherwise specifically provided in this Agreement, without the prior written consent of Contango, the rights to cause Contango to register Registrable Securities granted to the Purchasers by Contango under this Article II may not be transferred or assigned by the Purchasers.

Section 2.7 Aggregation of Registrable Securities. 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 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.

Section 3.5 Specific Performance.

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.

Each of the parties hereto irrevocably agrees that any legal action or proceeding with respect to this Agreement or the Transactions shall be brought and determined by courts of the State of Texas located in Houston, Texas and the federal courts of the United States of America located in Houston, Texas, and each of the parties hereto irrevocably submits to the exclusive jurisdiction of such courts solely in respect of any legal proceeding arising out of or related to this Agreement.

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. Notwithstanding the foregoing, any amendment, waiver, consent or modification of, or supplement to, this Agreement shall require approval of a majority of the members of the board of directors of Contango not affiliated with John C. Goff.

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, general or limited partner, manager, member, stockholder or Affiliate of any of the foregoing, whether by the enforcement of any assessment or by any legal or equitable proceeding, or by virtue of any applicable law, it being expressly agreed and acknowledged that no personal liability whatsoever shall attach to, be imposed on or otherwise by incurred by 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 any of their respective assignees,

12

or any former, current or future director, officer, employee, agent, general or limited partner, manager, member, stockholder or Affiliate of any of the foregoing, as such, for any obligations of Contango, the Purchasers, Selling Holders or their respective permitted assignees under this Agreement or any documents or instruments delivered in connection herewith or therewith or for any claim based on, in respect of or by reason of such obligation or its creation, except in each case for any assignee of the Purchasers or a Selling Holder hereunder.

Contango shall use its commercially reasonable efforts to cause such initial Shelf Registration Statement to become effective no later than 120 days from its initial filing.

A Shelf Registration Statement filed pursuant to this Section 2.l(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 five Business Days of such date, Contango shall provide the Holders with written notice of the effectiveness of a Shelf Registration Statement.

(b) 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.

(c) 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 60 consecutive days or an aggregate of 180 days in any 365-day period. Upon disclosure of such information or the termination of the condition described above, Contango shall provide prompt notice 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 Sale Procedures.

(a) 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) 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

4

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;

(iii) 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;

(iv) 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;

(v) 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;

5

(vi) 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;

(vii) 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;

(viii) 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;

(ix) provide a transfer agent and registrar for all Registrable Securities covered by such registration statement; and

(x) 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.

(b) Each Selling Holder, upon receipt of notice from Contango of the happening of any event of the kind described in Section 2.2(b)(v), 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 2.2(b)(v) 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 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 2.3 Cooperation by Holders. Contango shall have no obligation to include Registrable Securities of a Holder in the Shelf Registration Statement if such Selling Holder has failed to timely furnish such information which, in the opinion of counsel to Contango, is reasonably required in order for the registration statement or prospectus supplement, as applicable, to comply with the Securities Act.

6

Section 2.4 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 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, and the fees and disbursements of Contango’s independent public accountants and counsel for Contango. Except as otherwise provided in Section 2.5 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, transfer taxes and fees of counsel allocable to the sale of the Registrable Securities.

(b) Expenses. Contango will pay all reasonable Registration Expenses in connection with a Shelf Registration Statement, whether or not any sale is made pursuant to such Shelf Registration Statement.

Section 2.5 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, employees, agents, representatives and managers, and each Person, if any, who controls such Selling Holder within the meaning of the Securities Act and the Exchange Act, and its directors, officers, employees, agents, representatives and managers, 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

7

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, employee, 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.

(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 2.5(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 2.5 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.

8

(d) Contribution. If the indemnification provided for in this Section 2.5 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 2.5 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 2.6 Transfer or Assignment of Registration Rights. Except as otherwise specifically provided in this Agreement, without the prior written consent of Contango, the rights to cause Contango to register Registrable Securities granted to the Purchasers by Contango under this Article II may not be transferred or assigned by the Purchasers.

Section 2.7 Aggregation of Registrable Securities. 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 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.

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. Notwithstanding the foregoing, any amendment, waiver, consent or modification of, or supplement to, this Agreement shall require approval of a majority of the members of the board of directors of Contango not affiliated with John C. Goff.

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, general or limited partner, manager, member, stockholder or Affiliate of any of the foregoing, whether by the enforcement of any assessment or by any legal or equitable proceeding, or by virtue of any applicable law, it being expressly agreed and acknowledged that no personal liability whatsoever shall attach to, be imposed on or otherwise by incurred by 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 any of their respective assignees,

C. In consideration of the mutual covenants and agreements herein contained and of the loans, extensions of credit and commitments hereinafter referred to, the parties hereto agree as follows:

ARTICLE I

DEFINITIONS AND ACCOUNTING MATTERS

Section 1.01 Terms Defined Above. As used in this Agreement, each term defined above has the meaning indicated above.

Section 1.02 Certain Defined Terms. As used in this Agreement, the following terms have the meanings specified below:

“Adjusted LIBO Rate” means, with respect to any Eurodollar Borrowing for any Interest Period, an interest rate per annum (rounded upwards, if necessary, to the next 1/16 of 1%) equal to (a) the LIBO Rate for such Interest Period multiplied by (b) the Statutory Reserve Rate.

“Administrative Agent” means JPMorgan in its capacity as administrative agent hereunder, or any successor administrative agent as provided in Section 11.06.

“Administrative Questionnaire” means an Administrative Questionnaire in a form supplied by the Administrative Agent.

“Affected Loans” has the meaning assigned to such term in Section 5.05.

“Affiliate” means, with respect to a specified Person, another Person that directly, or indirectly through one or more intermediaries, Controls or is Controlled by or is under common Control with the Person specified.

1

“Agents” means, collectively, the Administrative Agent and the Syndication Agents; and “Agent” means the Administrative Agent or any Syndication Agent, as the context requires.

“Aggregate Maximum Credit Amounts” at any time shall equal the sum of the Maximum Credit Amounts, as the same may be reduced or terminated pursuant to Section 2.06. The initial Aggregate Maximum Credit Amounts of the Lenders is $500,000,000.

“Agreement” means this Credit Agreement, as the same may from time to time be amended, modified, supplemented or restated.

“Alternate Base Rate” means, for any day, a rate per annum equal to the greatest of (a) the Prime Rate in effect on such day, (b) the NYFRB Rate in effect on such day plus ¹⁄₂ of 1.0% and (c) the Adjusted LIBO Rate for a one month Interest Period on such day (or if such day is not a Business Day, the immediately preceding Business Day) plus 1.0%; provided that, for the purpose of this definition, the Adjusted LIBO Rate for any day shall be based on the LIBO Screen Rate (or if the LIBO Screen Rate is not available for such one month Interest Period, the Interpolated Rate) at approximately 11:00 a.m. London time on such day. Any change in the Alternate Base Rate due to a change in the Prime Rate, the NYFRB Rate or the Adjusted LIBO Rate shall be effective from and including the effective date of such change in the Prime Rate, the NYFRB Rate or the Adjusted LIBO Rate, respectively. If the Alternate Base Rate is being used as an alternate rate of interest pursuant to Section 3.03, then the Alternate Base Rate shall be the greater of clauses (a) and (b) above and shall be determined without reference to clause (c) above. For the avoidance of doubt, if the Alternate Base Rate as determined pursuant to the foregoing would be less than 1.00%, such rate shall be deemed to be 1.00% for purposes of this Agreement.

“AML Laws” means all laws, rules, and regulations of any jurisdiction applicable to any Lender, the Borrower, the Borrower’s Subsidiaries or any Guarantor from time to time concerning or relating to anti-money laundering.

2

Each change in the Applicable Margin and the Commitment Fee Rate shall apply during the period commencing on the effective date of such change in the Borrowing Base Utilization Percentage and ending on the date immediately preceding the effective date of the next such change; provided, however, that if at any time the Borrower fails to deliver a Reserve Report pursuant to Section 8.12(a), then the “Applicable Margin” and the “Commitment Fee Rate” shall mean the rate per annum set forth on the grid when the Borrowing Base Utilization Percentage is at its highest level, beginning on the date of such failure until such Reserve Report is delivered.

“Applicable Percentage” means, with respect to any Lender at any time, the percentage of the Aggregate Maximum Credit Amounts represented by such Lender’s Maximum Credit Amount; provided that if the Commitments have terminated or expired, each Lender’s Applicable Percentage shall be determined based upon the Commitments most recently in effect.
