 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 

  
 11 

 
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 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. 

  
 16 

 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. 
 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.

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,
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

book-entry notation representing such Registrable Security restricting transfer of such Registrable Security has been removed.

 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 

(a) 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 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. 

ARTICLE III

Section 3.4 Recapitalization (Exchanges, etc. Affecting the Registrable Securities). The provisions

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. 
 Section 3.8 Governing Law, Submission to Jurisdiction. NOTWITHSTANDING
THE PLACE WHERE THIS AGREEMENT MAY BE EXECUTED BY ANY OF THE PARTIES HERETO, THE PARTIES EXPRESSLY AGREE THAT THIS AGREEMENT SHALL BE GOVERNED BY AND CONSTRUED UNDER THE LAWS OF THE STATE OF TEXAS, WITHOUT REGARD TO THE CONFLICT OF LAW PROVISIONS OF
SUCH JURISDICTION. Each of the parties hereto irrevocably agrees that any legal action or proceeding with respect to this Agreement or the transactions contemplated hereby 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. 
 Section 3.9 Waiver of Jury Trial. THE PARTIES TO THIS AGREEMENT EACH HEREBY
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 

  
 18 

 
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 AGREEMENT WITH ANY COURT AS WRITTEN EVIDENCE OF THE CONSENT OF THE PARTIES HERETO TO THE WAIVER OF THEIR RIGHT TO TRIAL BY JURY. 

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. This Agreement and the Purchase Agreement are intended
by the parties as a final expression of their agreement and intended to be a complete and exclusive statement of the agreement and understanding of the parties hereto in respect of the subject 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,
general or limited partner, manager, member, stockholder or Affiliate of any of the foregoing, 

  
 19 

 
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, 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. 

Section 3.15 Interpretation. Article and Section references in this Agreement are references to the corresponding
Article and Section to this Agreement, unless otherwise specified. All references to instruments, documents, contracts and agreements are references to such instruments, documents, contracts and agreements as the same may be amended, supplemented
