(a) Notwithstanding anything in this Agreement to the contrary, no Investor shall Transfer any Securities or interests therein except
(i) in compliance with Sections 2.01(b), 2.01(c) or 2.01(d), as applicable, and (ii) pursuant to an effective registration statement filed under the Securities Act, or pursuant to an exemption thereunder and, in each
case, in compliance with applicable state and foreign securities laws and nothing herein shall be construed to require the Company to register such Securities pursuant to the Securities Act or any other federal, state or foreign securities laws,
except as may be required by the Registration Rights Agreement. Prior to any such Transfer of Securities, each Investor shall have notified the Company of the proposed disposition and shall have furnished the Company with a detailed statement of the
circumstances surrounding the proposed disposition, and, if reasonably requested by the Company, such Investor shall have furnished the Company with an opinion of counsel, reasonably satisfactory to the Company, that such disposition will not
require registration under the Securities Act. In addition, the shares of Preferred Stock and the Warrants 

  
 6 









 
represent a non-detachable unit. The Preferred Stock may not be Transferred separately from the Warrants attached thereto, and the Warrants may not be Transferred separately from the Preferred
Stock attached thereto. Each Investor consents to the Company making a notation on its records and giving instructions to any transfer agent of the Securities in order to implement the restrictions on Transfer established in this
Section 2.01. Prior to an Initial Public Offering, any Transfer of Securities shall be subject to the transferee agreeing to be bound by the provisions of this Agreement as an “Investor” and the execution by such
transferee of a joinder or other document evidencing its agreement to such provisions. If any Transfer of Securities permitted hereunder would require filings with or the approval of any Governmental Authority under the Hart-Scott-Rodino Antitrust
Improvements Act of 1976, as amended, or any other foreign antitrust laws or requirements, the Company shall use commercially reasonable efforts to cooperate with the applicable Investors in connection with any such requirements applicable to the
Company or to such Investors; provided that, except as otherwise provided in Section 7.03 of the Securities Purchase Agreement, the Company shall not be required to make any payments to any Governmental Authority or reimburse or pay any
expenses in connection therewith. 
 (b) Except as permitted by Section 2.08, no Investor may Transfer any Preferred Stock (or
any associated Warrant) to a Competitor. 
 (c) Except as permitted by Section 2.08, prior to an Initial Public Offering, no
Investor may Transfer any Common Stock to a Competitor unless such Investor has first offered to Transfer such Common Stock to PXP. Such offer shall be made by an irrevocable written offer (the “Transfer Offer Notice”) to sell such
Common Stock that must specify: 
 (i) the identity of the Competitor; 

(ii) the price per share of Common Stock which the Competitor is proposing to pay; 

(iii) the manner in which the consideration is to be paid; 

(iv) the number of shares of Common Stock proposed to be Transferred (the “Transfer Stock”); and 

(v) any other material terms and conditions upon which the Transfer is to be made, including a copy of the offer from the Competitor, if any.

 PXP shall have 15 days (the “Transfer Option Period”) after actual receipt of the Transfer Offer Notice within which to
make a binding and irrevocable election to acquire all of the Transfer Stock upon the terms and conditions contained in the Transfer Offer Notice. If, within the Transfer Option Period, PXP makes an irrevocable election to acquire all of the
Transfer Stock, then PXP will close such transaction no later than the later to occur of (A) the closing date set forth in the Transfer Offer Notice, if any and (B) 30 days after the last day of the Transfer Option Period. If, within the
Transfer Option Period, PXP does not make an irrevocable election to acquire all of the Transfer Stock, then the Investor may Transfer the Transfer Stock to the transferee in the Transfer Option Notice upon terms not more favorable than those
described in the Transfer Offer Notice no later than 60 days after the end of the Transfer Option Period; provided, that such 60 day period will be extended if, and only to the extent that, such proposed Transfer requires filings with or
approvals from any Governmental Authority under the Hart-Scott-Rodino 

  
 7 









 
Antitrust Improvements Act of 1976, as amended, or any other foreign antitrust laws or requirement. If a Transfer is not made by the Investor within the time period contemplated by the preceding
sentence, then the terms of this Section 2.01(c) shall apply to any subsequent proposed Transfer of Common Stock by an Investor to a Competitor. 

(d) Except as permitted by Section 2.08, prior to an Initial Public Offering, no Investor may Transfer Common Stock to a Person
who is not a Competitor unless such Investor has provided PXP with prior written notice of the Investor’s intent to Transfer such Common Stock and either (A) PXP does not make an irrevocable written offer to acquire such Common Stock
within 30 days of such written notice or (B) PXP makes such a written offer and the Investor consummates a sale at a higher price for such Common Stock within 60 days of PXP’s offer; provided, that such 60 day period will be
extended if, and only to the extent that, such proposed Transfer requires filings with or approvals from any Governmental Authority under the Hart-Scott-Rodino Antitrust Improvements Act of 1976, as amended, or any other foreign antitrust laws or
requirement. If a Transfer is not made by the Investor within the time period contemplated by the preceding sentence, the terms of this Section 2.01(d) shall apply to any subsequent Transfer of Common Stock by an Investor to Person who
is not a Competitor. 
 (e) The Preferred Stock (and shares of Class A Common Stock or Common Stock issuable upon conversion thereof)
will bear the legends set forth in the Certificate of Designation. Each Warrant shall bear the legends set forth in the form of Warrant. 

(f) The Company shall promptly reissue certificates without legends or instruct the Transfer Agent to permit the Transfer of the Securities
without restriction at the request of any Investor thereof if the Securities have been registered pursuant to or under the Securities Act or the Investor shall have obtained an opinion of counsel, certification or other information reasonably
acceptable to the Company to the effect that the securities proposed to be disposed of may lawfully be disposed of without registration, qualification or legend. 

(g) PXP shall not, and shall not permit any Affiliate to, Transfer any shares of Common Stock or other Equity Securities held by it unless the
transferee agrees to be bound by the provisions of Sections 2.01(d), the requirements to vote for or consent to any purchase of assets for which Majority Preferred Approval has been obtained under Section 2.02(c),
Section 2.05(c), Section 2.07(d) and Article III, applicable to PXP in its capacity as a holder of Class B Common Stock or Common Stock, and delivers to the Company and the Investors a joinder or other document
evidencing its agreement to such provisions. Such joinder shall provide that such transferee is a “Party” for purposes of the relevant sections of this Agreement described in the preceding sentence. 

Section 2.02. Permitted Business; Business Opportunities; Exclusivity. 

(a) Permitted Business. The Company shall not engage in any business or activity other than those involving exploiting, exploring for,
acquiring, developing, processing, gathering, marketing or transporting oil, natural gas and other hydrocarbons from oil and natural gas properties located in the Gulf of Mexico in water depths of 500 feet or more (“Deepwater GOM

 8 









 (b) Business Opportunities. The Company hereby agrees and acknowledges that, other than
with respect to the right to purchase certain assets from PXP pursuant to Section 2.02(c), (i) the Company shall have no interest in and waives any interest in, or expectancy that PXP or any other Party hereto, or any of their
respective Affiliates, or any of the forgoing Persons’ respective partners, members, managers, officers or directors, shall be required to offer it the opportunity to participate in, any business opportunities that may arise from time to time,
(ii) PXP and the other Parties hereto shall not be required to provide any interest in any such business opportunities to the Company and (iii) the Company shall not have any reasonable expectation of receiving any interest in any such
business opportunities. 
 (c) Exclusivity. PXP may acquire additional Deepwater GOM Assets (including equity interests of a company
engaged in a Permitted Business), provided that, within thirty (30) days after the closing of such acquisition, PXP offers, by written notice, to sell such assets to the Company for an amount equal to the purchase price of such assets
plus PXP’s reasonable transaction costs. The Company shall notify PXP as to whether it will acquire such additional Deepwater GOM Assets within thirty (30) days after receipt of a written offer from PXP. The Company shall take all action
necessary or appropriate to seek the vote or consent to approve such offer by the holders of Preferred Stock and, prior to an Initial Public Offering, the holders of Common Shares, each voting separately as a class (except that the holders of Common
Shares shall vote together as a single class), and in connection therewith shall provide all such holders with all material information relating to such offer and such assets. PXP agrees, and agrees to cause its Affiliates, to vote or consent all of
their respective Common Shares (if such vote or consent is sought prior to an Initial Public Offering and determined by the Company to be necessary) and Preferred Stock entitled to vote or consent to approve such offer in the same proportion as the
holders of the Preferred Stock other than PXP or its Affiliates, voting separately as a class, not later than three (3) days after the vote or consent thereon by the holders of the Preferred Stock other than PXP or its Affiliates. The Company
shall accept such offer if (and only if) it has obtained: (i) prior to an Initial Public Offering, the Majority Preferred Approval (without any further requirement of approval by the Board of Directors); and (ii) after an Initial Public
Offering, the approval of the Board of Directors. If the Company agrees to acquire additional Deepwater GOM Assets prior to an Initial Public Offering under this Section 2.02(c), then each of the holders of Common Stock, Class A
Common Stock and Class B Common Stock (the “Common Stockholders”) and Preferred Stockholders shall contribute their proportionate share (determined on an as-converted basis) of any capital necessary to fund such acquisition through
the purchase from the Company of additional shares of Class A Common Stock at a price of $20.00 per share; provided, however, that if any holder of Common Stock, Class A Common Stock or Class B Common Stock fails to purchase such
additional shares of Class A Common Stock, then PXP shall acquire such additional shares of Class A Common Stock. If the foregoing applicable approval is obtained, then the Company shall (and PXP shall cause the Company to) take all action
necessary or appropriate to accept such offer within thirty (30) days after receipt of the written offer from PXP. Notwithstanding the foregoing, the restrictions and requirements in this section shall not apply (1) from and after the

(6) to additional Deepwater GOM Assets acquired by PXP after the date hereof which are subject to any area of mutual interest, buy-back, preferential or similar pre-emptive right to purchase in favor of third parties under the terms of
Applicable Contracts; provided that PXP shall offer to the Company pursuant to this Section 2.02(c) any additional Deepwater GOM Assets for which such third parties have failed to exercise their area of mutual interest, buy-back,
preferential or similar pre-emptive rights to purchase and the time periods under this Section 2.02(c) shall be extended by the number of days such rights of third parties remain open. Within three days after any acquisition of Deepwater
GOM Assets by PXP pursuant to clause (6) of the preceding sentence, PXP shall notify the Company (including the Preferred Nominee) and the Investors of such acquisition and the time periods for the exercise of such third party rights;
provided, however, that PXP shall not be required to notify the Investors if it is contractually prohibited from providing such notification (but only to the extent of such prohibition). Notwithstanding the foregoing, in the event PXP
acquires leases that constitute Deepwater GOM Assets (“Deepwater Lease Assets”) and offers such Deepwater Lease Assets to the Company in accordance with the first sentence of this Section 2.02(c), then to the extent the
Company has available funds available under the Approved Budget for the purchase of Deepwater Lease Assets (up to an aggregate of $40 million), the Company shall be required to purchase such assets from PXP (and shall not be required to obtain
Majority Preferred Approval for such purchase). The Company shall purchase such assets from PXP for an amount equal to the purchase price of such assets plus PXP’s reasonable transaction costs (without the requirement for the Common
Stockholders, PXP or the Preferred Stockholders to contribute their proportionate share of the purchase price of such Deepwater Lease Assets). If the Company accepts an offer from PXP to purchase certain assets pursuant to this
Section 2.02(c) (including Deepwater Lease Assets), then PXP and the Company will enter into an asset purchase agreement with customary terms that are reasonably acceptable to each party; provided, however, it shall not be
reasonable for the Company to refuse to execute an asset purchase agreement that contains identical or less burdensome terms than the terms by which PXP acquired the applicable assets. 

Section 2.03. Projects Outside of the Approved Budget. 

(a) Until the earlier of (i) an Initial Public Offering, (ii) the fifth anniversary of the Closing Date or (iii) the receipt by
the Holders of written notice (the “Budget Approval Termination Notice”) from the Company that the Preferred Nominee’s approval rights over the Approved Budget has terminated (which notice may not be received more than 10 days
prior to the date on which a definitive agreement for an Applicable Sale Transaction in connection with Section 2.10 will be entered into in the good faith reasonable belief of the Company), the Company will operate under a budget that
is approved by at least a majority of the members of the Board of Directors, including the Preferred Nominee (such approved budget, an “Approved Budget”). The initial Approved Budget is attached to the Securities Purchase Agreement
as Exhibit A thereto. All Property Costs are included in the Approved Budget. Subject to the next sentence, the Company shall not incur or commit to incur or make any expenditures or payments (including in respect of redemption of any Equity
Securities other than the Securities) in amounts 

  
 10 









 
that exceed the amounts set forth in the Approved Budget (or, in the case of specific items described in clause (e) below, in excess of the limits for such items set forth in clause (e))
(other than the repayment of indebtedness by the Company using its cash flow or a Cost Overrun funded in accordance with Section 2.04). If the Board of Directors (by majority vote) desires the Company to undertake a project or incur or
commit to incur or make any other expenditures or payments that are not included in the Approved Budget (or, in the case of specific items described in clause (e) below, in excess of the limits for such items set forth in clause (e)) (other
than the repayment of indebtedness by the Company using its cash flow or a Cost Overrun funded in accordance with Section 2.04) but that are in the good faith determination of the Board reasonably expected to be funded or committed
within the twelve months following such determination, then PXP will have the right to fund such project or other expenditures or payments through additional capital contributions to the Company in exchange for shares of Class A Common Stock at
a price of $20.00 per share. Each Preferred Stockholder will have a right to participate in such funding by purchasing on the same terms as PXP its Pro Rata Percentage of any shares of Class A Common Stock sold in order to fund such project or
other expenditures or payments. 
 (b) The Company shall notify the Preferred Stockholders in writing of its intention to issue shares of
Class A Common Stock pursuant to Section 2.03(a), which notice shall set forth the number of shares of Class A Common Stock being offered, the price per share at which such shares are to be sold and the proposed use of proceeds
of such offering. Each of the Preferred Stockholders shall have fifteen (15) days from the giving of such notice to decide whether or not to purchase some or all of its Pro Rata Percentage of such Class A Common Stock. To the extent that
any of the shares of Class A Common Stock are not subscribed for during such fifteen (15)-day period, the Company shall send a notice to each Preferred Stockholder that fully subscribed for its Pro Rata Percentage of the unsubscribed
Class A Common Stock to be sold. The Preferred Stockholders shall have three (3) Business Days after receipt of such notice to notify the Company of its election to purchase all or a portion of such unsubscribed shares on a pro rata basis
with any similarly electing Preferred Stockholders. 
 (c) If all the shares of Class A Common Stock proposed to be sold or issued by
the Company pursuant to this Section 2.03 are not elected to be purchased as provided in Section 2.03(b), the Company may, following the expiration of the period provided in Section 2.03(b), offer the remaining
unsubscribed portion of such shares of Class A Common Stock to any person or persons at a price not less than, and upon terms not materially more favorable to the offeree than, those specified in Section 2.03(b). 

(d) Promptly following the completion of the procedures set forth in Section 2.03(b) and Section 2.03(c), the Company
shall notify PXP and each Preferred Stockholder electing to purchase shares of Class A Common Stock under Section 2.03(b) of the number of shares of Class A Common Stock that PXP or such holder, as applicable, is entitled to
purchase under this Section 2.03 and the proposed closing date of such purchase which closing shall occur not less than fifteen (15) Business Days following the date of such notice. At the closing, the Company shall cause the
Transfer Agent to (i) record the issuance of the shares purchased by PXP or such Preferred Stockholder, as applicable, in accordance with its customary book-entry procedures promptly after payment therefor to the account designated by the
Company by wire transfer of immediately available funds and (ii) deliver evidence to the purchasers of the issuance of the Class A Common Shares, represented by book entry on the books and records of the Transfer Agent and meeting the
requirements of the organizational documents of the Company. 

  
 11 









 (e) The Approved Budget includes expected costs for (i) the development of the Lucius
Project and (ii) the exploratory drilling of the initial well on the Phobos Prospect, in an aggregate amount in the case of clauses (i) and (ii) not to exceed $550 million, and (iii) a portion of the leases to be acquired in
connection with the Permitted Business and seismic data, in an aggregate amount not to exceed $40 million. Any funds not used under clause (iii) may be applied to expenditures under clauses (i) and (ii) and, to such extent, may exceed
the $550 million sublimit. The Approved Budget will permit the repayment of any indebtedness of the Company using its cash flow. 
 (f) The
Investors acknowledge that the Company may grant to a transferee of Common Stock (or other Equity Securities) as a result of an Excluded Transfer similar rights to purchase its Pro Rata Percentage of the Class A Common Stock sold pursuant to
this Section 2.03. 
 (g) If the Company has issued a Budget Approval Termination Notice pursuant to
Section 2.03(a), and an Applicable Sale Transaction does not close within 120 days of the date of such notice, then the Exit Right Commencement Date shall be accelerated to the 120th
day after the delivery of such Budget Approval Termination Notice. 
 Section 2.04. Cost Overrun Support. 

(a) In the event that the Company’s actual expenses relating to the projects described in clauses (i) and (ii) of the first
sentence of Section 2.03(e) (the “Development Plan”) exceed those set forth in the Approved Budget and exceed any cash flow to the Company generated from the Deepwater Assets (each such additional expense, a
“Cost Overrun”), then to the extent the Company has obtained Majority Preferred Approval, such Cost Overruns may be funded with additional indebtedness of the Company. If any Cost Overruns are to be funded or committed instead with
equity issued by the Company as determined by the Board of Directors, and the Preferred Stockholders (by Majority Preferred Approval) have agreed to participate in such funding, then the Common Stockholders and the Preferred Stockholders may
contribute their Pro Rata Percentages of any capital necessary to fund the Company Cost Overruns through the purchase of (i) in the case of Preferred Stockholders, additional Preferred Stock (together with additional non-detachable Warrants in
the same percentage as were issued in connection with the initial issuance of the Preferred Stock) at an aggregate price of $1,000 per share and (ii) in the case of Common Stockholders, Class A Common Stock at a price of $20.00 per share.
If any funding by Preferred Stockholders is not funded ratably by all holders, then (i) the Preferred Shares issued to the holders participating in such funding will be designated as senior to the Preferred Stock but otherwise will be issued on
substantially the same terms, including providing the same Warrant coverage as that provided in the initial issuance of the Preferred Stock and Warrants, and (ii) the Company shall take all necessary action to create the new class of preferred
stock that shall be senior to the Preferred Stock and the Common Stockholders party to this Agreement and the Preferred Stockholders shall approve (and are hereby deemed to have approved) an amendment to the Certificate of Incorporation to designate
such new class of preferred stock and all such parties shall enter into such amendments of the Transaction 

  
 12 









 
Documents as may be reasonably necessary to reflect the creation of such new class of preferred stock and to extend the rights and obligations applicable to the Preferred Stock to such new
preferred stock (subject to the seniority of the Preferred Stock). Such newly issued Preferred Shares shall be entitled to vote together with the Preferred Stock as a single class on all matters subject to a class vote and shall have all rights of
“Preferred Stock” under the Transaction Documents. 
 (b) If Majority Preferred Approval is obtained for funding the Cost Overrun
through Class A Common Stock and Preferred Stock, the Company shall notify the Preferred Stockholders in writing of its intention to issue shares of Class A Common Stock and Preferred Stock pursuant to Section 2.04(a). Each of
the Preferred Stockholders shall have fifteen (15) days from the giving of such notice to decide whether or not to purchase its ratable portion of the shares so offered (based on the proportion of the total number of shares of Preferred Stock
then outstanding held by such Preferred Stockholder). To the extent that any of the shares of Preferred Stock are not subscribed for during such fifteen (15)-day period, the Company shall send a notice to each Preferred Stockholder that fully
subscribed for its ratable portion of the unsubscribed Preferred Stock to be sold. The Preferred Stockholders shall have three (3) Business Days after receipt of such notice to notify the Company of its election to purchase all or a portion of
such unsubscribed shares on a pro rata basis with any similarly electing Preferred Stockholders. 
 (c) If the Company Cost Overruns are not
funded with (i) additional indebtedness or (ii) equity contributions pursuant to Section 2.04(b) above, then PXP shall have the right to fund such Cost Overruns (up to the portion not funded through purchases of Preferred Stock
by the Preferred Stockholders under Section 2.04(b)) through the purchase of additional Class A Common Stock at a price of $20.00 per share. 

(d) Promptly following the completion of the procedures set forth in Section 2.04(b) and Section 2.04(c), the Company
shall notify PXP and each Preferred Stockholder electing to purchase shares of Preferred Stock under Section 2.04(b) of the number of shares of Preferred Stock (or senior preferred stock) or Class A Common Stock that PXP or such
holder, as applicable, is entitled to purchase under this Section 2.04 and the proposed closing date of such purchase which closing shall occur not less than fifteen (15) Business Days following the date of such notice. At the
closing, the Company shall (i) cause the Transfer Agent to record the issuance of the shares of Preferred Stock (or senior preferred stock) or Class A Common Stock purchased by PXP or such holder, as applicable, in accordance with its
customary book-entry procedures promptly after payment therefor to the account designated by the Company by wire transfer of immediately available funds and (ii) deliver evidence to the purchasers of the issuance of the Class A Common
Shares, represented by book entry on the books and records of the Transfer Agent and meeting the requirements of the organizational documents of the Company. 

(e) The Investors acknowledge that the Company may grant to a transferee of Common Stock (or other Equity Securities) as a result of an
Excluded Transfer similar rights to purchase its Pro Rata Percentage of the Class A Common Stock sold pursuant to this Section 2.04.

 Section 2.05. Board of Directors; Board Observers; Governance. 

(a) Prior to a Qualified IPO, (i) (A) the Board of Directors will consist of not more than seven (7) members and (B) the
holders of a majority of the shares of Class B Common Stock shall have the right to appoint all but one (1) such director to the Board of Directors (the “Class B Nominees”), (ii) for so long as any of the Preferred Stock
is outstanding, the holders of Preferred Stock will have the right to appoint one (1) director (the “Preferred Nominee”), it being understood that EIG Global Energy Partners (“EIG”) will appoint the Preferred
Nominee as long as it owns at least 20% of the outstanding Preferred Stock and after such time, the Preferred Nominee will be appointed by Majority Preferred Approval, and (iii) the Preferred Stockholders will have the right to appoint two
(2) observers to the Board of Directors (and any committee of the Board of Directors or any management, executive or similar committee established by the Company) by Majority Preferred Approval. On the Closing Date, the initial Board of
Directors will consist of five (5) members; the Class B Nominees will be James C. Flores, Winston M. Talbert, John F. Wombwell and Doss R. Bourgeois, and the Preferred Nominee will be Kurt Talbot. All subsidiaries of the Company shall have
boards of directors identical in size and composition to the Company’s Board of Directors. 
 (b) The Company shall cause the Class B
Nominees and the Preferred Nominee (together, the “Nominees”), pursuant to this Section 2.05, to be nominated for election at an annual or special stockholders meeting of the Company and shall take all actions necessary
or advisable to cause the Board of Directors to recommend that the stockholders vote “FOR”, and solicit proxies for, the election of the Nominee(s). If a Nominee (or any successor Nominee appointed pursuant to this paragraph) ceases
for any reason to serve as a director of the Company after having been duly appointed or elected, then, the holders of a majority of the shares of Class B Common Stock, EIG or the Preferred Stockholders holding a majority of the Preferred
Stock, as appropriate, shall have the right to nominate a replacement for such Nominee to hold office for the remaining unexpired term of such Nominee. Any Nominee appointed or elected to the Company’s Board of Directors may be removed by the
party that originally nominated such person and only by such party except that any such Nominee may be removed for cause in accordance with applicable Law or the Company’s certificate of incorporation and bylaws and shall (A) have the
requisite skill and experience to serve as a director of a company traded on a Principal Market, and (B) not be prohibited or disqualified from serving as a director of the Company pursuant to any rule or regulation of the SEC or any Principal
Market or by applicable Law. 
 (c) Each Party shall vote all Equity Securities held by it for the election to the Board of Directors of all
individuals nominated in accordance with this Section 2.05 and the removal from the Board of Directors of all directors proposed to be removed by the party that nominated them in accordance with this Section 2.05 and shall
take all actions required on its behalf to give effect to the agreements set forth in this Section 2.05. Each Party shall use all reasonable efforts to cause each director nominated by such stockholder to vote for the election to the
Board of Directors of all individuals nominated in accordance with this Section 2.05. 
 (d) The Company shall use commercially
reasonable efforts to cause the Board of Directors to convene meetings at least once every three months. Upon any failure by the Company to convene a meeting at least every three months, a director nominated under Section 2.05 shall be
empowered to convene such meeting. 

  
 14 









 (e) The Company shall reimburse each director who is not an employee of the Company and each
observer for his or her reasonable out of pocket expenses including travel incurred in connection with the attendance of meetings of the Board of Directors or any committee thereof. 

(f) The Company, PXP and the Investors agree and acknowledge that PXP is hereby granted an irrevocable proxy coupled with an interest to vote
the Escrowed Class A Shares (as defined in the Certificate of Designation). 
 Section 2.06. Minority Protection. 

(a) For so long as any shares of Preferred Stock remain outstanding the Company shall not voluntarily commence any case, proceeding or other
action under any existing or future law of any jurisdiction, relating to bankruptcy, insolvency, reorganization or relief of debtors, seeking to have an order for relief entered with respect to the Company, or seeking to adjudicate the Company a
bankrupt or insolvent, or seeking reorganization, arrangement, adjustment, winding up, liquidation, dissolution, composition or other relief with respect to it or its debts or take any actions described in Section 4 of the Certificate of
Designation, in all cases, without first obtaining Majority Preferred Approval or such higher vote of Preferred Stockholders as may be required by law and subject to the termination of certain of those approval rights under Section 4(b) of the
Certificate of Designation upon the occurrence of an Initial Public Offering. 
 (b) Pursuant to Section 12(f) of the Certificate of
Designation, if the Company provides written notice to the Preferred Stockholders of its intention to take any action for which Majority Preferred Approval is required to be obtained pursuant to Section 4 of the Certificate of Designation and
restricts the Holders to twenty (20) Business Days from the giving of the notice to object to such action, then the failure by any Holder to respond to such notice with its objection within such twenty (20) Business Day period shall be
deemed a consent by such Holder to the proposed action or actions contained in the Company’s written notice. 
 (c) Subject to the
other provisions herein, PXP shall not, and shall cause its Affiliates not to, acquire any shares of Preferred Stock unless such proposed acquisition receives Majority Preferred Approval. 

(d) The Company shall provide written notice to the Preferred Stockholders of its intention to take any action for which Majority Preferred
Approval is required to be obtained pursuant to this Section 2.06 which notice shall contain reasonable detail regarding the matter for which approval is being sought and shall include a statement that failure to respond within the time
period set forth in this Section 2.06 shall result in a deemed approval of the matters set forth in the notice. The Preferred Stockholders shall then have twenty (20) Business Days from the giving of such notice to object to such
action. Failure by any Preferred Stockholder to respond to such notice within such twenty (20) Business Day period shall be deemed a consent by such Preferred Stockholder to the proposed action or actions contained in the Company’s written
notice. 
 (e) Except as specifically provided for herein, in the Certificate of Designation or as provided by applicable law, the Preferred
Stockholders shall not vote as a class on any matter. 

  
 15 









 Section 2.07. Liquidity/Exit. 

(a) At any time after the fourth anniversary of the Closing Date (the “Exit Right Commencement Date”), the Preferred
Stockholders acting by Majority Preferred Approval shall have the right to cause the Company to use its commercially reasonable efforts to consummate an Exit Event (an “Exit Event Election”), with the form of such Exit Event to be
selected by the Company. Upon an Exit Event Election by the Preferred Stockholders, the Company shall promptly engage a nationally recognized investment bank to advise the Company in connection with such process. The form of Exit Event to be pursued
by the Company shall be selected by the Company in consultation with the investment bank selected by it. At the request of any Preferred Stockholders, the Company shall (and shall endeavor to make representatives of the investment bank selected by
it available to) meet with the Preferred Stockholders to advise them regarding status of the Exit Event selection process. Following an Exit Event Election, the Company shall use commercially reasonable efforts to consummate an Exit Event. If the
holders of Preferred Stock have voted in favor of an Exit Event by Majority Preferred Approval, then all holders of Preferred Stock shall be deemed to have voted all of their shares of Preferred Stock in favor of such action and shall be required to
take all such other actions as may be reasonably necessary to consummate such action. 
 (b) If the Company fails to consummate an Exit
Event after having used its commercially reasonable efforts to consummate such Exit Event, then at any time more than two (2) years after the date of the Preferred Stockholders’ prior request for an Exit Event, the Preferred Stockholders,
acting by Majority Preferred Approval, may again cause the Company to use its commercially reasonable efforts to consummate an Exit Event, with the form of such Exit Event to be selected by the Company and implemented in accordance with this
Section 2.07. Preferred Stockholders shall have the right to instruct the Company to attempt an Exit Event every two (2) years until an Exit Event is completed. 

(c) The following penalties shall occur if an Exit Event has been requested and is not consummated on or before the Exit Event Deadline: 

(i) the Conversion Price (as defined in the Certificate of Designation) will immediately and automatically be adjusted such that all the
issued and outstanding shares of Preferred Stock on an as-converted basis taken together with the Warrant Shares, in the aggregate, shall constitute 49% of the Common Shares on a Fully Diluted Basis; and 

(ii) PXP shall be required to purchase $300 million of junior preferred stock in the Company which shall have the terms set forth on
Exhibit A hereto, and the Company shall use the proceeds thereof to retire the Credit Agreement, with any remaining proceeds not so used therefor being retained by the Company for general corporate purposes. Copies of all documents relating
to any such junior preferred stock shall be delivered to the Holders upon request. 
 (d) PXP and each other holder of Common Shares (or any
securities convertible, exchangeable or exercisable into such stock) agrees to (i) reasonably cooperate with the Company and the Preferred Stockholders in connection with the consummation of any Exit Event and (ii) take such actions
(including vote its shares of capital stock) as may be reasonably requested by the Preferred Nominee in connection with consummating the Exit Event selected by 

  
 16 









 
the Company, and shall grant customary voting proxies to such persons or their designees in connection therewith and to take such actions (including voting its shares of capital stock) as may be
reasonably necessary to create the junior preferred stock in the event of the penalty pursuant to (c)(ii) above. 
 (e) If PXP or the
Company elects the Repurchase Option as its Exit Event, the Preferred Stockholders, acting by Majority Preferred Approval, may elect to terminate the Exit Event process once if they are not satisfied with the determination of Fair Market Value for
any reason. In such event, such process shall not be deemed an Exit Event for any purpose hereunder. 
 (f) If PXP or the Company elects the
Repurchase Option and consummates such an Exit Event, notwithstanding any other provisions herein to the contrary, the Company shall not effect an Initial Public Offering for a period of twelve (12) months after the consummation of such Exit
Event. 
 (g) If PXP or the Company consummates an Exit Event as described herein or the Company consummates an Initial Public Offering,
then the rights of the Preferred Stockholders to cause the Company to use its commercially reasonable efforts to consummate an Exit Event shall terminate. 

(h) If the Preferred Stockholders have voted in favor of an Exit Event by Majority Preferred Approval, then all Preferred Stockholders shall
be deemed to have voted all of their shares of Preferred Stock in favor of such action and shall be required to take all such other actions as may be reasonably necessary to consummate such action. 

(i) For the avoidance of doubt, only an Exit Event described in clause (ii) of the definition thereof shall be treated as a Liquidation
Event. 
 Section 2.08. Tag Along Rights. 

(a) In the event that PXP or any of its Affiliates (other than a transferee pursuant to an Excluded Transfer) intend to Transfer Common Shares
of the Company, in one transaction or a series of related transactions, to an unaffiliated third party purchaser (a “Proposed Purchaser”) other than in connection with an Excluded Transfer, PXP shall give notice thereof (a
“Co-Sale Notice”) to the other equity holders (the “Remaining Equityholders”). 
 (b) The Co-Sale Notice
shall specify: 
 (i) the identity of the Proposed Purchaser; 

(ii) the price per Common Share which the Proposed Purchaser is proposing to pay; 

(iii) the manner in which the consideration is to be paid; 

(iv) the number of Common Shares proposed to be Transferred; and 

(v) any other material terms and conditions upon which the Transfer is to be made, including a copy of the offer from the Proposed Purchaser,
if any. 

  
 17 









 (c) The Remaining Equityholders shall be entitled within fifteen (15) days after
receipt of the Co-Sale Notice, to notify PXP or its subsidiary that they wish to sell a ratable number of shares of Preferred Stock, Class A Common Stock and Warrants on an as-converted basis at the proposed sale price specified in the Co-Sale
Notice by sending a counter-notice which shall specify the number of shares of Preferred Stock, Class A Common Stock and Warrants on an as-converted basis which the relevant Remaining Equityholder wishes to sell. Each such Remaining
Equityholders shall be entitled to sell up to its Pro Rata Percentage of the number of Common Shares proposed to be Transferred in such transaction as set forth in the Co-Sale Notice. In order to exercise its co-sale right under this section, each
Remaining Equityholder shall not be required to convert its shares of Preferred Stock into Common Shares and/or exercise its Warrants to the extent of the Common Shares it sells pursuant to such co-sale right; provided, however, that any
transferee of a Remaining Equityholder shall be required to convert any shares of Preferred Stock into Common Shares and/or to exercise any Warrants so acquired on the closing date of any such acquisition as a condition to any Transfer under this
Section 2.08, including any transfer by the party issuing the Co-Sale Notice. The purchase price in respect of any share of Preferred Stock shall be equal to the price to be paid per Common Share in such transaction multiplied by the
number of Conversion Shares then issuable upon conversion of a share of Preferred Stock, and the price to be paid for any Warrant shall be equal to the price to be paid per Common Share in such transaction multiplied by the Warrant Shares issuable
upon exercise thereof, less the aggregate exercise price under such Warrant. To the extent any Remaining Equityholder exercises such co-sale right, the number of Shares which PXP or its subsidiary may sell pursuant to the Co-Sale Notice shall be
correspondingly reduced by the number of Common Shares that such Remaining Equityholders are entitled to, and have indicated they wish to, sell (the “Remaining Equityholder Shares”), unless the Proposed Purchaser has agreed to
increase the number of Common Shares it is willing to purchase.  
 (d) Following the expiration of the fifteen (15) days
from the date the Remaining Equityholders receive the Co-Sale Notice, PXP or its subsidiary shall be entitled to sell to the Proposed Purchaser on the terms set forth in the Co-Sale Notice a number of Common Shares not exceeding the number specified
in the Co-Sale Notice less, if applicable pursuant to (c) above, the Remaining Equityholders Shares, provided that at the same time the Proposed Purchaser also purchases the Remaining Equityholders Shares on the same terms set forth in
the Co-Sale Notice. As of the closing date for such purchase, the Remaining Equityholders shall Transfer good and valid title to the Remaining Equityholder Shares, free and clear of all liens, encumbrances, equities or claims. In connection with any
such purchase and sale of Remaining Equityholder Shares, no Remaining Equityholder shall be required to provide any representations, warranties or indemnities, other than customary several (and not joint) representations, warranties and indemnities
concerning (i) such holder’s valid title to and ownership of Equityholder Shares, free of all liens, claims and encumbrances (excluding those arising under applicable securities laws), (ii) such holder’s authority, power and
right to enter into and consummate such sale and the absence of any violation of its organizational documents as a result of such sale, (iii) the absence of any violation, default or acceleration of any agreement to which such holder is subject
or by which its assets are bound as a result of the sale, and (iv) the absence of, or compliance with, any governmental or third party consents, approvals, filings or notifications required to be obtained or made by such holder in connection
with the sale.

 Section 2.09. Preemptive Rights. 

(a) Prior to an Initial Public Offering, to the extent that the Company intends to issue Equity Securities, the Company will send a notice to
PXP and each of the Investors of its intention to issue Equity Securities (other than the shares excluded by Section 2.09(b)) and shall first offer to the Investors and PXP the opportunity to invest in such Equity Securities on the same
terms, so as (and to the extent necessary) to enable the Investors and PXP to maintain their respective Pro Rata Percentage ownership of the Company. The Company shall notify the Investors and PXP in writing of its intention, with a description of
the Equity Securities to be sold and the price and the terms and conditions upon which the Company proposes to issue the same. Each of the Investors and PXP shall have fifteen (15) days from the giving of such notice to decide whether or not to
purchase some or all of its Pro Rata Percentage of such offering. To the extent that any of the Equity Securities are not subscribed for during such fifteen (15)-day period, the Company shall send a notice to PXP and each Investor that fully
subscribed for its Pro Rata Percentage of the Equity Securities offering them the unsubscribed shares. The Investors and PXP shall have three (3) Business Days after receipt of such notice to notify the Company of their election to purchase all
or a portion of such unsubscribed shares. 
 (b) The rights established by this Section 2.09 shall not apply to (i) any
Excluded Issuances or (ii) Equity Securities issued to support projects outside the Approved Budget pursuant to Section 2.03 or to support Cost Overruns pursuant to Section 2.04. 

(c) If all the Equity Securities proposed to be sold or issued by the Company pursuant to Section 2.09(a) are not elected to be
purchased as provided in Section 2.09(a), the Company may, for a period of up to thirty (30) Business Days following the expiration of the period provided in Section 2.09(a), offer the remaining unsubscribed portion of
such Equity Securities to any person or persons, including Investors, at a price not less than, and upon terms not materially more favorable to the offeree than, those specified in Section 2.09(a). 

(d) Promptly following the completion of the procedures set forth in Section 2.09(a), the Company shall notify PXP and each
Investor electing to purchase Equity Securities under Section 2.09(a) of the number of shares of Equity Securities that PXP and such Investor, as applicable, is entitled to purchase under this Section 2.09 and the proposed
closing date of such purchase which closing shall occur not less than fifteen (15) Business Days following the date of such notice. At the closing, the Company shall cause the Transfer Agent to record the issuance of the Equity Securities
purchased by PXP and such Investor, as applicable, in accordance with its customary book-entry procedures promptly after payment therefor to the account designated by the Company by wire transfer of immediately available funds. 

(e) The Investors acknowledge that the Company may grant similar rights to other holders of the Company’s Equity Securities to purchase
their pro rata portion of the Equity Securities sold pursuant to this Section 2.09. 
 Section 2.10. Company Sale PXP
Call Right. 
 (a) Prior to an Initial Public Offering, PXP shall have the right to purchase, and the Investors shall be required to
sell to PXP, for cash, a portion of the outstanding Equity Securities 

  
 19 









 
(from the Investors as well as other holders of Equity Securities), if such purchase is necessary (and only to the extent necessary), in the reasonable discretion of PXP, to allow PXP to achieve
or maintain (based on the then outstanding Equity Securities of the Company) ownership of the Company satisfying the requirements of Section 1504(a)(2) of the Internal Revenue Code of 1986, as amended (the type and amount of Equity Securities
determined to be subject to the call right in accordance with this Section 2.10, the “Sale Called Securities”), at the price and in accordance with the procedures set forth in this Section 2.10. Any such
purchase shall be made first from holders of Equity Securities other than the Investors and PXP and only after the purchase of all Equity Securities held by Persons other than the Investors and PXP, to the extent necessary ratably from among the
Equity Securities held by the Investors, based on the number of Common Shares represented by such Equity Securities on an as converted or as exercised basis. The call right set forth in this Section 2.10 may only be exercised by PXP in
connection with an Applicable Sale Transaction. To exercise such call right, PXP must deliver written notice to each Investor (the “Sale Call Notice”) at least five (5) but not more than twenty (20) days prior to the
proposed purchase date under this Section 2.10 (the “Sale Call Date”). The Sale Call Date shall be not more than ten (10) days prior to the date a definitive agreement for the sale of all or substantially all of the
assets or stock of the Company will be entered into in the good faith reasonable belief of PXP or the Company. The Sale Call Notice shall set forth (i) the Sale Call Date, (ii) the Sale Called Securities to be purchased and the Sale Call
Purchase Price in respect thereof and (iii) reasonable details regarding the Applicable Sale Transaction. 
 (b) On any Sale Call Date,
PXP shall purchase, and each Investor shall sell to PXP, the Sale Called Securities for a purchase price equal to: (i) for each share of Preferred Stock being purchased, the Liquidation Preference in respect thereof, (ii) for each Warrant
being purchased, the excess of the Class A Purchase Price in respect thereof over the exercise price in respect thereof and (iii) for any shares of Class A Common Stock being purchased, the Class A Purchase Price in respect
thereof (collectively, the “Sale Call Purchase Price”). 
 (c) On the Sale Call Date, each Investor shall deliver an
executed transfer instruction to the Transfer Agent requesting transfer to PXP by book entry of any Preferred Stock, Class A Common Stock and Warrants, as applicable, included in the Securities being purchased from such Investor, together with
executed signature guarantees and other applicable transfer instruments in respect thereof, against payment of the Sale Call Purchase Price in respect of such Equity Securities to the account designated by such Investor by wire transfer of
immediately available funds. 
 (d) Upon purchase by PXP, each share of Preferred Stock acquired by PXP shall be automatically converted
into Class A Common Stock at the Conversion Rate then in effect. 
 Section 2.11. Other PXP Call Right; Tax Adjustment on
Common Shares. 
 (a) At any time on or after the fifth anniversary of the Closing Date, PXP may exercise a call right to purchase all,
but not less than all, of the outstanding Preferred Stock and Warrants, for cash, at a price and in accordance with the procedures set forth in this Section 2.11; provided, however, that the Investors, by Majority Preferred
Approval, shall have a right, exercisable not more than twice, to terminate such call if they are not satisfied with the determination of Fair Market Value. In such event, PXP may not exercise its call right under this


  
 20 









 
Section 2.11 for six months after such Majority Preferred Approval. To exercise such call right, PXP must deliver written notice to each Investor (the “Full Call
Notice”) at least fifteen (15) days prior to the proposed purchase date under this Section 2.11 (the “Full Call Date”). The Full Call Notice shall set forth the Full Call Date, the Preferred Stock and
Warrants to be purchased and the Full Call Purchase Price in respect thereof. Any Investor may at its option elect to have all shares of Class A Common Stock held by it (other than Conversion Shares and Warrant Shares) repurchased by the
Company on the Full Call Date by delivering written notice of such election to the Company prior to the Full Call Date. 
 (b) On any Full
Call Date, PXP shall purchase, and each Investor shall sell to PXP, (i) the Preferred Stock held by such Investor for a cash purchase price per share equal to the Liquidation Preference in respect thereof, (ii) the Warrants held by such
Investor for a cash purchase price per Warrant equal to the excess of the Class A Purchase Price in respect thereof over the exercise price in respect thereof and (iii) any shares of Class A Common Stock (other than Conversion Shares
and Warrant Shares) such Investor has elected to include in such sale under Section 2.11(a), for a cash purchase price equal to the Class A Purchase Price in respect thereof (collectively, the “Full Call Purchase
Price”). 
 (c) On the Full Call Date, each Investor shall deliver an executed transfer instruction to the Transfer Agent
requesting transfer to PXP by book entry of the Preferred Stock and Warrants and any shares of Class A Common Stock being purchased from such Investor, together with executed signature guarantees and other applicable transfer instruments in
respect thereof, against payment of the Full Call Purchase Price in respect thereof to the account designated by such Investor by wire transfer of immediately available funds. 

(d) Upon purchase by PXP, each share of Preferred Stock acquired by PXP shall be automatically converted into Class A Common Stock at the
Conversion Rate then in effect, each in-the-money Warrant shall be deemed automatically exercised for Class A Common Stock at the applicable exercise price and each out-of-the-money Warrant shall be automatically cancelled. If the Company
exercises a call right under this Section 2.11, PXP agrees that it will not cause or permit the Company to effect an Initial Public Offering for a period of twelve (12) months after the date of such purchase. 

(e) Notwithstanding anything to the contrary in this Section 2.11, if an Investor has elected to convert shares of Preferred Stock
or to exercise Warrants after the receipt of a Full Call Notice and on or before the Full Call Date, each such share of Preferred Stock or Warrant (or any Conversion Shares and Warrant Shares issued in connection with such conversion or exercise)
(collectively, the “Full Call Conversion Shares”) shall not be subject to purchase under this Section 2.11. Each Investor shall be entitled to deliver a notice of conversion of Preferred Stock in accordance with
Section 6 of the Certificate of Designation and to deliver a notice of exercise of Warrants in connection with Section 3(a) of the Warrants at any time prior to the closing of the Full Call Purchase. 

(f) PXP agrees to comply with the obligations set forth in Section 3(b) of the Warrants. 

  
 21 









 (g) In connection with a Tax Adjustment Event, shares of Class A Common Stock (but not
Conversion Shares or Warrant Shares except as provided in clause (i) of the last sentence of the definition of Tax Adjustment Amount and without duplication if any such shares are entitled to a Tax Adjustment Amount under any other provision of
a Transaction Document), shall be entitled to receive, as additional consideration for such shares in connection with the transfer thereof, the Tax Adjustment Amount in respect of such shares (in addition to other amounts payable in respect of such
Class A Shares in connection with such transaction), such amount payable by (i) the purchaser in connection with such transaction or, if not paid by the purchaser, the Company, or (ii) the Company in connection with any such event in
which there is no purchaser. 
 Section 2.12. Information Rights. 

(a) Subject to clauses (e) and (f) below, the Company shall provide the Investors with the following information: 

(i) Notice and a reasonably detailed description of the occurrence of any event directly concerning the Company or its subsidiaries that the
Company determines in its good faith judgment is material to the Preferred Stockholders or Warrant holders, in each case within ten (10) Business Days following the occurrence thereof; 

(ii) Unaudited financial statements of the Company within seventy-five (75) days after the end of each of the first three
(3) quarters of the Company’s fiscal year; 
 (iii) Annual audited financial statements of the Company within one-hundred twenty
(120) days after the end of the Company’s fiscal year; 
 (iv) A third-party reserve report covering the Company’s assets
within one-hundred twenty (120) days after the end of each calendar year, which report will be prepared by an independent engineering firm as of the end of such year; 

(v) Monthly, a summary of gross cash receipts of the Company and its subsidiaries and joint interest billing payments made by such persons
during such month; 
 (vi) Monthly, production and operating reports on the properties of the Company and its subsidiaries; 

(vii) Monthly, copies of bank statements of the Company and its subsidiaries; and 

(viii) Thirty (30) days’ prior notice of any event or transaction which would constitute a Liquidation Event (as defined in the
Certificate of Designation), redemption event or trigger any other call or repurchase of Preferred Stock or Warrants. 
 (b) In conjunction
with the exercise by PXP of any call right or redemption right or in the event of a Liquidation Event or an Exit Event, the Company will agree to provide (x) such other information and reports regarding the Company and its properties and
business as any Preferred Stockholder or Warrant holder may reasonably request from time to time, including technical information, production and operations reports, budgets and forecasts and (y) reasonable inspection rights for such Preferred
Stockholder and its technical advisors. 

  
 22 









 (c) The annual and quarterly financial statements described above will include a description of
the business activities that took place during the period covered by the financial statements and a summary of the Company’s business plan for the following quarter. Notwithstanding the foregoing, the Company need not disclose in the business
plan summary any information that would require public disclosure by PXP in accordance with Regulation FD to any Preferred Stockholder or Warrant holder who does not enter into a customary confidentiality agreement. 

(d) The Company shall permit the Investors or their respective representatives to inspect any of the books of account and other records of the
Company and to discuss its business and affairs with the Company’s officers and its independent public accountants, all at such reasonable times during the Company’s usual business hours and upon reasonable prior notice (which shall not be
less than twenty-four (24) hours). Any information received by an Investor pursuant to this Section 2.12(d) shall be subject to the provisions of Section 3.15. 

(e) Provision of information to an Investor under clauses (a)(iv), (a)(vi) and (b) with respect to any prospect in which the Company has
entered into an operating agreement shall be subject, if required by the terms of the relevant operating agreement, to such Investor entering into a confidentiality agreement on the terms required under the relevant operating agreement. 

(f) The rights of the Investors to receive information pursuant to Section 2.12(a) shall cease upon the consummation of an Initial
Public Offering other than the rights to receive information pursuant to clauses (i), (iv) and (viii) of Section 2.12(a). 

Section 2.13. Guaranty. PXP will guarantee the Credit Agreement and any refinancing thereof on terms materially consistent with
the terms of the Credit Agreement until such time as (a) the guaranty thereof by PXP is no longer required by the lenders thereof and such release would not result in a decrease of availability under the Credit Agreement below $300 million
(provided, however, that such guaranty by PXP shall be automatically reinstated upon any decrease in the availability under the Credit Agreement below $300 million) or (b) subject to Section 2.06, the Company can refinance
the Credit Agreement utilizing a pledge of Company assets or other security on terms that are commercially reasonable without the PXP guaranty provided that (i) the availability under such refinanced Credit Agreement shall be not less than $300
million and (ii) such refinanced Credit Agreement shall not contain any cross default or cross acceleration to any indebtedness of PXP or any of its subsidiaries or contain covenants or defaults relating to PXP or any of its subsidiaries other
than the Company and its subsidiaries. Either PXP or the Preferred Stockholders may buyout the Credit Agreement from the lenders thereunder at par (or such lesser price as such lenders may agree to); provided that neither party will have any
rights to accelerate such indebtedness or foreclose on or attach the Company’s assets. 
 Section 2.14. Valid Issuance; No
Liens. The Company hereby represents and warrants to the Investor that any Equity Securities of the Company issued or delivered to the Investor pursuant to Sections 2.02(c), 2.03, 2.04 or 2.09 of this Agreement
shall, after payment therefor in 

  
 23 









 
accordance with the terms hereof, be validly issued, fully paid and non-assessable Equity Securities of the Company and free and clear of all liens, other than Transfer restrictions under the
Transaction Documents. 
 Section 2.15. Spin. Without Majority Preferred Approval, PXP will not commence or effect a spin out of
the shares of stock of the Company held by PXP or any of its subsidiaries to the stockholders of PXP, except in a transaction where: (i) the conditions set forth in clauses (ii) and (iii) of the definition of Forced Conversion
Conditions are satisfied at or prior to the consummation of such transaction and (ii) the Chief Executive Officer of the Company and PXP are the same individual after the consummation of such transaction.

the negotiation and preparation of this Agreement and, consequently, each Party hereby waives the application of any rule of Law that would otherwise be applicable in connection with the interpretation of this Agreement, including but not limited to
any rule of Law to the effect that any provision of this Agreement will be interpreted or construed against the Party whose counsel drafted that provision. 

Section 3.13. Specific Performance. The Parties agree that irreparable damage may occur in the event that any of the provisions of

non-breaching Party shall be entitled (in addition to any other remedy that may be available to it, including monetary damages) to seek and obtain (a) a decree or order of specific performance to enforce the observance and performance of such
obligation, and (b) an injunction restraining such breach or threatened breach. Each Party further agrees that no other Party or any other Person shall be required to obtain, furnish or post any bond or similar instrument in connection with or
as a condition to obtaining any remedy referred to in this Section 3.13, and each Party hereto irrevocably waives any right it may have to require the obtaining, furnishing or posting of any such bond or similar instrument. Each Party
further agrees that it shall not object to the granting of an order of specific performance, an injunction or other equitable relief on the basis that there exists an adequate remedy at law. 

Section 3.14. Severability. Any term or provision of this Agreement which is determined by a court of competent jurisdiction to be

affecting the validity or enforceability of any of the terms or provisions of this Agreement in any other jurisdiction, and if any provision of this Agreement is determined to be so broad as to be unenforceable, the provision shall be interpreted to
be only so broad as is enforceable, in all cases so long as neither the economic nor legal substance of the transactions contemplated hereby is affected in any manner adverse to any Party or its equityholders. Upon any such determination, the
Parties shall negotiate in good faith in an effort to agree upon a suitable and equitable substitute provision to effect the original intent of the Parties as closely as possible and to the end that the transactions contemplated hereby shall be
fulfilled to the maximum extent possible. 

  
 27 









 Section 3.15. Confidentiality. Each Investor agrees that all non-public information
relating to the Company shall be kept confidential by such Investor and shall not be disclosed by such Investor in any manner whatsoever; provided, however, that any of such information may be disclosed (i) unless and to the extent the

prohibition applies to the information being disclosed and which notice shall specify the class of persons affected by the prohibition), to such Investor’s Affiliates, to Persons who are (or who are prospective) beneficial owners of equity
interests in such Investor or its Affiliates and to managers, directors, officers, employees and authorized representatives (including attorneys, accountants, consultants, bankers and financial advisors) of such Investor and of such Investor’s
Affiliates (collectively, for purposes of this Section 3.15, “Representatives”), each of which Representatives shall be bound by the provisions of this Section 3.15 or substantially similar terms;
(ii) to the extent to which the Company consents in writing; (iii) to the extent not in violation of applicable law, if disclosure is with respect to the terms of an Investor’s investment in the Company pursuant to this Agreement or
any other Transaction Document and the performance of that investment (whether in such Investor’s or its Affiliate’s fundraising materials or otherwise); (iv) by an Investor or Representative to the extent reasonably necessary in
connection with such Investor’s enforcement of its rights under this Agreement or any other Transaction Document; or (v) by any Investor or Representative to the extent that such Investor or Representative has received advice from its
counsel that it is legally compelled to do so, provided that, prior to making such disclosure, the Investor or Representative, as the case may be, uses reasonable efforts to preserve the confidentiality of the information, including
consulting with the Company regarding such disclosure and, if reasonably requested by the Company, assisting the Company, at the Company’s expense, in seeking a protective order to prevent the requested disclosure. 

Section 3.16. No Additional Commitment. PXP and the Company acknowledge and agree that the Investors have not made any
representation, undertaking, commitment or agreement to provide or assist the Company or its Affiliates in obtaining any financing, investment or other assistance, other than the purchase of the Securities pursuant to the Securities Purchase
Agreement, provided that the foregoing shall not limit any commitment of an Investor under Sections 2.02, 2.03, 2.04 and 2.09 of this Agreement to the extent (in the case of Section 2.02) Majority Preferred
Approval for such investment is obtained or (in the case of Sections 2.03, 2.04 and 2.09) an Investor has elected in writing to purchase securities under the terms of those provisions. Except as expressly set forth in and
required by the terms of Section 2.02 (after Majority Preferred Approval of the relevant purchase) or to the extent an Investor has elected in writing to purchase securities in accordance with the terms of Sections 2.03,
2.04 and 2.09, each Investor shall have the right, in its sole and absolute discretion, to refuse or decline to participate in any other financing of or investment in the Company or its Affiliates, and shall have no obligation to
assist or cooperate with the Company and its Affiliates in obtaining any financing, investment or other assistance. 

  
 28 









 Section 3.17. Certain Fair Market Value Determinations. Notwithstanding anything to
the contrary herein, whenever the Board of Directors is permitted to determine fair market value in good faith (including for purposes of determining whether the exercise price or strike price of any Equity Security that is a warrant or option is
less than the fair market value of a Common Share), then if the proceeds or value of such proposed transaction, issuance or delivery in question exceeds $100 million in the aggregate, the Board of Director shall determine such fair market value
after receipt of an appraisal or other valuation from an independent, nationally recognized appraiser, accounting firm or investment bank, at the Company’s cost; provided, however, if such determination is being made in connection with a
transaction in which Fair Market Value is being determined, then such determination shall be used.
