NOW, THEREFORE, in consideration of the premises, representations, warranties and the mutual covenants contained in this Agreement, and for other good and valuable consideration, the receipt, sufficiency and adequacy of which are hereby acknowledged, the parties hereto agree as follows:

AGREEMENT

1.        Sale and Purchase.

(a)      Forward Purchase Securities.

(i)     At Purchasers’ election, the Purchasers shall collectively purchase from HighPeak Energy, and HighPeak Energy shall issue and sell to the Purchasers, an aggregate of up to 15,000,000 units of Forward Purchase Securities (“Forward Purchase Units”), with each Forward Purchase Unit consisting of one Forward Purchase Share and one-third of one whole Forward Purchase Warrant, for $10.00 per Forward Purchase Unit, or an aggregate maximum amount of $150,000,000 (the purchase price for the actual number of Forward Purchase Units so purchased, the “Forward Purchase Price”), in such amounts as the Purchasers may designate on Exhibit A hereto in connection with their election, but in any event subject to clause 1(a)(ii).

(ii)     The number of Forward Purchase Units to be issued and sold by HighPeak Energy and purchased by the Purchasers hereunder shall not exceed the lesser of (A) that number which, after payment of the aggregate Forward Purchase Price by the Purchasers, will result in gross proceeds to HighPeak Energy in an aggregate amount equal to the amount of funds necessary for HighPeak Energy and Pure to consummate the Business Combination and pay related fees and expenses, less amounts available to Pure from the trust account established for the benefit of the holders of the Public Shares in the IPO (the “Trust Account”) (after giving effect to any redemptions of Public Shares), any other equity financing source obtained by Pure for such purpose at or prior to the consummation of the Business Combination, and amounts the Purchasers or their affiliates have expended to repurchase Public Warrants in any tender offer, plus any additional amounts mutually agreed by Pure and the Purchasers that may be retained by HighPeak Energy for working capital or other purposes and (B) 15,000,000 Forward Purchase Units.

(iii)     Each Forward Purchase Warrant will have the same terms as the Private Placement Warrants, and will be subject to the terms and conditions of the Warrant Agreement, dated as of April 12, 2018, by and between Pure and Continental Stock Transfer & Trust Company, as Warrant Agent, in connection with the IPO (the “Warrant Agreement” and assigned by Pure to HighPeak Energy and amended in connection with the Business Combination Closing). Each Forward Purchase Warrant will entitle the holder thereof to purchase one share of HighPeak Energy Common Stock at a price of $11.50 per share, subject to adjustment as described in the Warrant Agreement, and only whole Forward Purchase Warrants will be exercisable. The Forward Purchase Warrants will become exercisable 30 days after the Business Combination Closing, and will expire five years after the Business Combination Closing or earlier upon the liquidation of HighPeak Energy, as described in the Warrant Agreement. The Forward Purchase Warrants will be non-redeemable and exercisable on a cashless basis so long as they are held by the Purchasers or their Transferees (as defined below). If the Forward Purchase Warrants are held by Persons (as defined below) other than the Purchasers or their Transferees, the Forward Purchase Warrants will have the same terms as the Public Warrants, as set forth in the Warrant Agreement.

(iv)     HighPeak Energy shall deliver a notice (the “Closing Notice”) to the Purchasers (which such Closing Notice shall be deemed to have been delivered to the Purchasers if delivered to HPEP I pursuant to the terms of the Original Agreement), following the close of business two (2) Business Days before the Business Combination Closing, specifying the date of the Business Combination Closing and instructions for wiring the Forward Purchase Price. If the Purchasers previously delivered a completed Exhibit A to HighPeak Energy prior to the time at which HighPeak Energy is required to deliver the Closing Notice, then HighPeak Energy shall also include a copy of the completed Exhibit A along with the Closing Notice. If the Purchasers did not previously deliver a completed Exhibit A to HighPeak Energy prior to the time at which HighPeak Energy is required to deliver the Closing Notice, then no later than one (1) Business Day before the Business Combination Closing date as specified in the Closing Notice, the Purchasers shall deliver a completed Exhibit A to HighPeak Energy, specifying the number of Forward Purchase Units each Purchaser elects to purchase pursuant to the terms of this Agreement. The closing of the sale of Forward Purchase Units (the “Forward Closing”) shall be on the same date and immediately prior to the Business Combination Closing (such date being referred to as the “Forward Closing Date”).

(v)     On or before the Forward Closing, but in any event prior to or simultaneous with the Business Combination Closing, the Purchasers shall deliver to HighPeak Energy, to be held in escrow until the Forward Closing, the aggregate Forward Purchase Price for the Forward Purchase Units to be purchased by wire transfer of U.S. dollars in immediately available funds to the account specified by HighPeak Energy in the Closing Notice. Immediately prior to the Forward Closing, (A) the aggregate Forward Purchase Price shall be released from escrow automatically and without further action by HighPeak Energy or the Purchasers, and (B) upon such release, HighPeak Energy shall issue the number the Forward Purchase Units so purchased to the Purchasers in the amounts designated by the Purchasers on Exhibit A in book-entry form, free and clear of any liens or other restrictions whatsoever (other than those arising under state or federal securities laws), registered in the name of the Purchasers (or their respective nominees in accordance with their respective delivery instructions), or to a custodian designated by the Purchasers, as applicable. In the event the Business Combination Closing does not occur on the date scheduled for closing, the Forward Closing shall not occur and the Company shall promptly (but not later than one (1) Business Day thereafter) return the aggregate Forward Purchase Price to the Purchasers, as applicable. For purposes of this Agreement, “Business Day” means any day, other than a Saturday or a Sunday, that is neither a legal holiday nor a day on which banking institutions are generally authorized or required by law or regulation to close in the City of New York, New York.

This Agreement, together with any documents, instruments and writings that are delivered pursuant hereto or referenced herein, constitute the entire agreement and understanding of the parties hereto in respect of its subject matter and supersedes all prior understandings, agreements, or representations by or among the parties hereto, written or oral, to the extent they relate in any way to the subject matter hereof or the transactions contemplated hereby.

(e)     Successors. All of the terms, agreements, covenants, representations, warranties, and conditions of this Agreement are binding upon, and inure to the benefit of and are enforceable by, the parties hereto and their respective successors.

(f)     Assignments. Except as otherwise specifically provided herein, no party hereto may assign either this Agreement or any of its rights, interests, or obligations hereunder without the prior written approval of the other party.

(g)     Counterparts. This Agreement may be executed in two or more counterparts, each of which will be deemed an original but all of which together will constitute one and the same instrument.

(h)     Headings. The section headings contained in this Agreement are inserted for convenience only and will not affect in any way the meaning or interpretation of this Agreement.

(i)     Governing Law. This Agreement, the entire relationship of the parties hereto, and any litigation between the parties (whether grounded in contract, tort, statute, law or equity) shall be governed by, construed in accordance with, and interpreted pursuant to the laws of the State of Delaware, without giving effect to its choice of laws principles.

(j)     Jurisdiction. The parties (i) submit to the jurisdiction of the state courts of Delaware and the United States District Court for the District of Delaware for the purpose of any suit, action or other proceeding arising out of or based upon this Agreement, (ii) agree not to commence any suit, action or other proceeding arising out of or based upon this Agreement except in state courts of Delaware or the United States District Court for the District of Delaware, and (iii) hereby waive, and agree not to assert, by way of motion, as a defense, or otherwise, in any such suit, action or proceeding, any claim that it is not subject personally to the jurisdiction of the above-named courts, that its property is exempt or immune from attachment or execution, that the suit, action or proceeding is brought in an inconvenient forum, that the venue of the suit, action or proceeding is improper or that this Agreement or the subject matter hereof may not be enforced in or by such court.

(k)     Waiver of Jury Trial. The parties hereto hereby waive any right to a jury trial in connection with any litigation pursuant to this Agreement and the transactions contemplated hereby.

13

(l)     Amendments. This Agreement may not be amended, modified or waived as to any particular provision, except with the prior written consent of the Company and the Purchasers; provided, however, that the Purchasers may amend Exhibit A without the consent of the Company upon notice thereof to the Company.

(m)     Severability. The provisions of this Agreement will be deemed severable and the invalidity or unenforceability of any provision will not affect the validity or enforceability of the other provisions hereof; provided that if any provision of this Agreement, as applied to any party hereto or to any circumstance, is adjudged by a governmental authority, arbitrator, or mediator not to be enforceable in accordance with its terms, the parties hereto agree that the governmental authority, arbitrator, or mediator making such determination will have the power to modify the provision in a manner consistent with its objectives such that it is enforceable, and/or to delete specific words or phrases, and in its reduced form, such provision will then be enforceable and will be enforced.

(n)     Expenses. Each of HighPeak Energy and the Purchasers will bear its own costs and expenses incurred in connection with the preparation, execution and performance of this Agreement and the consummation of the transactions contemplated hereby, including all fees and expenses of agents, representatives, financial advisors, legal counsel and accountants. HighPeak Energy shall be responsible for the fees of its transfer agent; stamp taxes and all The Depository Trust Company fees associated with the issuance of the Forward Purchase Securities and the securities issuable upon exercise of the Forward Purchase Warrants.

(o)     Construction. The parties hereto have participated jointly in the negotiation and drafting of this Agreement. If an ambiguity or question of intent or interpretation arises, this Agreement will be construed as if drafted jointly by the parties hereto and no presumption or burden of proof will arise favoring or disfavoring any party hereto because of the authorship of any provision of this Agreement. Any reference to any federal, state, local, or foreign law will be deemed also to refer to law as amended and all rules and regulations promulgated thereunder, unless the context requires otherwise. The words “include,” “includes,” and “including” will be deemed to be followed by “without limitation.” Pronouns in masculine, feminine, and neuter genders will be construed to include any other gender, and words in the singular form will be construed to include the plural and vice versa, unless the context otherwise requires. The words “this Agreement,” “herein,” “hereof,” “hereby,” “hereunder,” and words of similar import refer to this Agreement as a whole and not to any particular subdivision unless expressly so limited. The parties hereto intend that each representation, warranty, and covenant contained herein will have independent significance. If any party hereto has breached any representation, warranty, or covenant contained herein in any respect, the fact that there exists another representation, warranty or covenant relating to the same subject matter (regardless of the relative levels of specificity) which such party hereto has not breached will not detract from or mitigate the fact that such party hereto is in breach of the first representation, warranty, or covenant.

(p)     Waiver. No waiver by any party hereto of any default, misrepresentation, or breach of warranty or covenant hereunder, whether intentional or not, may be deemed to extend to any prior or subsequent default, misrepresentation, or breach of warranty or covenant hereunder or affect in any way any rights arising because of any prior or subsequent occurrence.

14

(q)     Specific Performance. The Purchasers agree that irreparable damage may occur in the event any provision of this Agreement was not performed by the Purchasers in accordance with the terms hereof and that HighPeak Energy shall be entitled to specific performance of the terms hereof, in addition to any other remedy at law or equity.

(r)     Liability. Any liability of the Purchasers under this Agreement shall be several and not joint.
