Prior to withholding, Parentco shall use commercially reasonable efforts to provide notice to a holder of Company Interests or ENPC Common Stock that withholding is required with respect to such payment. Notwithstanding the foregoing, no such notice is required in respect of any compensatory amounts or amount required to be withheld as a result of a failure to provide the certificates described in Section 2.3(a)(ix) or Section 2.3(b)(iv). To the extent that amounts are so withheld, such withheld amounts shall be treated for all purposes of this Agreement as having been paid to the holders of Company Interests or ENPC Interests, as applicable.

Except as set forth in the disclosure schedules delivered by the Company on the Execution Date (the “Company Disclosure Schedules”), the section numbers of which are numbered to correspond to the section

24

numbers of this Agreement to which they refer, the Company hereby represents and warrants to ENPC, as of the Execution Date and as of the Closing (or, if a representation and warranty is specifically made as of another date, such other date), as follows:

3.1 Organization and Qualification; Subsidiaries.

(a) Each of the Company and each Subsidiary of the Company following the Company Pre-Closing Transactions (each a “Company Subsidiary”) is a limited liability company, duly formed, validly existing and in good standing under the Laws of the State of Delaware. The Company and each Company Subsidiary (together, each a “Grey Rock Entity”) has the requisite limited liability company power and authority and all necessary governmental approvals to own, lease and operate its properties and to carry on its business as it is now being conducted, except where the failure to have such power, authority and governmental approvals has not had, individually or in the aggregate, a Material Adverse Effect on the Grey Rock Entities, taken as a whole (a “Company Material Adverse Effect”). Each Grey Rock Entity is duly qualified and in good standing to do business in each jurisdiction in which the business it is conducting, or the operation, ownership or leasing of its properties, makes such qualification necessary, other than where the failure to be duly organized, validly existing, to so qualify, to be in good standing or to have such requisite power and authority has not had, individually or in the aggregate, a Company Material Adverse Effect. The Company has heretofore made available to ENPC complete and correct copies of the Organizational Documents of each of the Grey Rock Entities and each of the Grey Rock Funds Governing Documents, each as in effect on the Execution Date. As of the Closing, the Organizational Documents of the Grey Rock Entities have not been amended in any respect from those made available to ENPC, except for any amendments expressly permitted by this Agreement and made in connection with this Agreement or the Transactions.

(b) Schedule 3.1(b) sets forth a true and complete list of all of the Company Subsidiaries, and with respect to each Company Subsidiary (a) its jurisdiction of organization, (b) its authorized membership interests or other equity interests (if applicable), and (c) the percentage of or number of issued and outstanding Interests and the record holders and beneficial owners thereof (as of both the Execution Date and immediately following the completion of the Company Pre-Closing Transactions). Other than the Company Subsidiaries following the Company Pre-Closing Transactions, the Company does not, and at the Closing will not, directly or indirectly own any Interest in, or any interest convertible into or exchangeable or exercisable for any Interest in, any corporation, limited liability company, partnership, joint venture or business association or other entity.

All of the outstanding Interests of the Grey Rock Entities (i) have been duly authorized and validly issued and are fully paid, free and clear of all Encumbrances (other than Permitted Encumbrances) and non-assessable (except to the extent non-assessability may be affected by Section 18-607 of the DLLCA); (ii) were issued in compliance in all material respects with applicable Law; and (iii) were not issued in breach or violation of any preemptive rights, rights of first refusal or other similar rights.

There are not any voting or other

agreements to which a Grey Rock Entity is a party or by which it is bound relating to the voting of any equity interests in any Grey Rock Entity. No Grey Rock Entity owns any Interest in any other Person or has any option, warrant, call, right, commitment or agreement to acquire any Interest in any other Person. Except as set forth on Schedule 3.2(b), no Interests in any Grey Rock Entity are issuable and no rights in connection with any Interests of the Grey Rock Entities will accelerate or otherwise become triggered (whether as to vesting, exercisability, convertibility or otherwise) as a result of the consummation of the Transactions contemplated by this Agreement and the Ancillary Documents.

(b) If a filing is required by the HSR Act, the Parent Parties shall or shall cause their Ultimate Parent Entity to and the Company shall or shall cause its Ultimate Parent Entity to: (i) as promptly as practicable and in any event no later than ten (10) Business Days after the date of this Agreement, file, or cause to be filed (and not withdraw), a Notification and Report Form under the HSR Act with the Federal Trade Commission (the “FTC”) and the Antitrust Division of the United States Department of Justice (the “Antitrust Division”) in connection with the Transactions; and (ii) use its reasonable best efforts to (A) respond as promptly as practicable to all inquiries received from the FTC or the Antitrust Division for additional information or documentation, (B) cause the waiting period under the HSR Act to terminate or expire at the earliest possible date and (C) avoid each and every impediment under the HSR Act with respect to the Transactions so as to enable the Closing to occur as soon as reasonably possible (and in any event not later than the End Date).

(c) No Party shall take any action that would hinder or delay the obtaining of clearance or the expiration of the required waiting period under the HSR Act.

6.6 Indemnification of Directors and Officers.

(a) Without limiting any other rights that any Indemnified Person may have pursuant to any employment agreement or indemnification agreement in effect on the Execution Date or otherwise, from the Closing and until the six year anniversary of the Closing, Parentco shall, and shall cause the Second Surviving Company and the Property Entities to, indemnify, defend and hold harmless each Person who is now, or has been at any time prior to the date of this Agreement or who becomes prior to the Closing, a manager or officer of any Grey Rock Entity or is or was serving at the request of a Grey Rock Entity as a manager, director or officer of another corporation, partnership, limited liability company, joint venture, Employee Benefit Plan, trust or other enterprise (the “Indemnified Persons”) against all losses, claims, damages, costs, fines, penalties, expenses (including attorneys’ and other professionals’ fees and expenses), liabilities or judgments or amounts that are paid in settlement (with the approval of the indemnifying party, which approval shall not be unreasonably withheld, delayed or conditioned), of or incurred in connection with any threatened or actual Proceeding to which such Indemnified Person is a party or is otherwise involved (including as a witness) based, in whole or in part, on or arising, in whole or in part, out of the fact that such Person is or was a manager or officer of a Grey Rock

52

Entity or is or was serving at the request of a Grey Rock Entity as a director, manager or officer of another corporation, partnership, limited liability company, joint venture, Employee Benefit Plan, trust or other enterprise or by reason of anything done or not done by such Person in any such capacity, whether pertaining to any act or omission occurring or existing prior to, at or after the Closing and whether asserted or claimed prior to, at or after the Closing (“Indemnified Liabilities”), including all Indemnified Liabilities based in whole or in part on, or arising in whole or in part out of, or pertaining to, this Agreement or the Transactions, in each case, to the fullest extent permitted under applicable Law (and Parentco shall, or shall cause a Subsidiary of Parentco to, pay expenses incurred in connection therewith in advance of the final disposition of any such Proceeding to each Indemnified Person to the fullest extent permitted under applicable Law). Without limiting the foregoing, in the event any such Proceeding is brought or threatened to be brought against any Indemnified Persons (whether arising before or after the Closing), (i) the Indemnified Persons may retain any Parent Party’s regularly engaged legal counsel or other counsel satisfactory to them, and Parentco shall, or shall cause a Subsidiary of Parentco to, pay all reasonable fees and expenses of such counsel for the Indemnified Persons as promptly as statements therefor accompanied by reasonable supporting documentation are received and (ii) Parentco shall, and shall cause the Second Surviving Company to, use their respective reasonable best efforts to assist in the defense of any such matter. Any Indemnified Person wishing to claim indemnification or advancement of expenses under this Section 6.6, upon learning of any such Proceeding, shall notify Parentco or the Second Surviving Company (but the failure so to notify shall not relieve Parentco from any obligations that it may have under this Section 6.6 except to the extent such failure materially prejudices Parentco’s position with respect to such claims). With respect to any determination of whether any Indemnified Person is entitled to indemnification by Parentco, the Second Surviving Company or any Property Entity under this Section 6.6, such Indemnified Person shall have the right to require that such determination be made by special, independent legal counsel selected by the Indemnified Person and approved by Parentco (which approval shall not be unreasonably withheld or delayed), and who has not otherwise performed material services for Parentco or the Indemnified Person within the last three (3) years.

(b) None of Parentco or any of its Subsidiaries (including the First Surviving Company and the Second Surviving Company) shall, or shall permit any of their respective Subsidiaries, to amend, repeal or otherwise modify any provision in the Organizational Documents of any Grey Rock Entity in any manner that would affect adversely the rights thereunder of any Indemnified Person to indemnification, exculpation and advancement except to the extent required by applicable Law.

(c) Subject to the following sentence, Parentco shall, and shall cause the Second Surviving Company and the Property Entities to, indemnify any Indemnified Person against all reasonable costs and expenses (including reasonable attorneys’ fees and expenses), such amounts to be payable in advance upon request as provided in Section 6.6(a), relating to the enforcement of such Indemnified Person’s rights under this Section 6.6 or under any Organizational Documents. Each Indemnified Person shall agree to refund all such amounts so paid by Parentco if it shall ultimately be determined by a final and non-appealable order of a court of competent jurisdiction that such Indemnified Person is not entitled to indemnification hereunder or thereunder.

(d) In the event that Parentco, the Second Surviving Company, any Property Entity or any of their respective successors or assigns (i) consolidates with or merges into any other Person and shall not be the continuing or surviving corporation or entity of such consolidation or merger or (ii) transfers all or substantially all of its properties and assets to any Person, then, in each such case, proper provisions shall be made so that the successors and assigns of such entity, as applicable, shall assume, or otherwise be bound by the obligations set forth in this Section 6.6. The provisions of this Section 6.6 are intended to be for the benefit of, and shall be enforceable by, the Parties and each Person entitled to indemnification or expense advancement pursuant to this Section 6.6, and such Person’s heirs and Representatives.

6.7 Agreement to Defend. In the event any Proceeding by any Governmental Entity or other Person is commenced that questions the validity or legality of the Transactions or seeks damages in connection therewith, the Parties agree to cooperate and use their reasonable best efforts to defend against and respond thereto.

53

6.8 Confidentiality; Public Announcements.

(a) ENPC and the Company acknowledge that the information being provided to them in connection with this Agreement and the consummation of the Transactions is subject to the terms of the Confidentiality Agreement, the terms of which are incorporated herein by reference. The Confidentiality Agreement shall continue to apply to all confidential information furnished hereunder or thereunder and any other activities contemplated hereby until terminated as set forth therein.

(b) The Parties shall issue a joint press release promptly following the execution of this Agreement, in form and substance mutually agreeable to the Parties. Following the Execution Date, a Party or its Representatives may issue a public announcement or other public disclosures required by applicable Law (including the Proxy Statement/Prospectus and any offering or other documents prepared in connection with any financing by any Party) subject to such Party using reasonable best efforts to afford the other Parties an opportunity to first review the content of the proposed disclosure and provide reasonable comment regarding same. No provision of this Agreement shall be deemed to restrict in any manner (a) any Party’s ability to communicate with its employees and financial and legal advisors in connection with the Transactions or the fact that the such Party has entered into this Agreement or (b) any Party’s ability to communicate with its equityholders and other investors (including future investors) the fact that such Party has entered into this Agreement. Except as provided in the foregoing provisions of this Section 6.8, the Parties will not, and will cause their respective Representatives not to, issue any other public announcements or make other public disclosures regarding this Agreement (including with respect to the execution of this Agreement) or the transactions contemplated hereby, without the prior written approval of the Company, in the case of a public announcement by ENPC or any other Parent Party, or ENPC, in the case of a public announcement by the Company.

6.9 Advice of Certain Matters; Control of Business. Subject to compliance with applicable Law, ENPC, on the one hand, and the Company, on the other hand, shall confer on a regular basis with each other, report on operational matters and shall promptly advise each other orally and in writing of any change or event having, a Company Material Adverse Effect, an ENPC Material Adverse Effect or Material Adverse Effect on any other Party, any Parent Party or any Property Entity, as the case may be, but the failure to so promptly advise in accordance with the foregoing shall not affect the rights or remedies of any Party to this Agreement. Except with respect to the HSR Act as provided in Section 6.5, the Parent Parties, on the one hand, and the Company, on the other hand, shall promptly provide each other (or their respective counsel) copies of all filings made by such Party or its Subsidiaries with the SEC or any other Governmental Entity in connection with this Agreement and the Transactions; provided, however, that materials provided to the another Party or its outside counsel may be redacted to remove references concerning the valuation of any Party and its Subsidiaries or as necessary to address reasonable privilege concerns. Without limiting in any way any Party’s rights or obligations under this Agreement, nothing contained in this Agreement shall give any Party, directly or indirectly, the right to Control or direct the other Parties and their respective Subsidiaries’ operations prior to the Closing. Prior to the Closing, each of the Parties shall exercise, consistent with the terms and conditions of this Agreement, complete Control and supervision over its and its Subsidiaries’ respective operations.

6.10 Tax Matters.

(a) The Company shall be responsible for all Company Taxes, including any Taxes arising from the Company Pre-Closing Transactions, but specifically excluding any Taxes under Sections 6221 through 6224 of the Code. From the Execution Date until the Closing Date, the Company shall be responsible for preparing and filing, or causing to be prepared and timely filed, all Tax Returns of the Company or the Property Entities that are required to be filed after the Execution Date but on or prior to the Closing Date. All Tax Returns described in this Section 6.10(a) shall be prepared in a manner consistent with past practice (unless otherwise required by applicable Law or this Agreement). The Company shall pay, and cause the Property Entities to pay, any Taxes reflected on such Tax Returns (other than, for the avoidance of doubt, Taxes with respect to Flow-Through Tax Returns for Tax periods ending on or before the Closing Date) described in this Section 6.10(a) and the Company shall be responsible for any failure to file such Tax Returns and to make such payments.

54

(b) Parentco or the Second Surviving Company shall prepare, or cause to be prepared, and timely file all Tax Returns required to be filed by the Company or the Property Entities (other than the Tax Returns set forth in Section 6.10(a)) which, for the avoidance of doubt, shall include any Tax Return required to be filed by the Company or the Property Entities after the Closing Date. All Tax Returns described in this Section 6.10(b) with respect to a taxable period (or portion thereof) ending on or before the Closing Date shall be prepared in a manner consistent with past practice (unless otherwise required by applicable Law or this Agreement). Parentco shall pay or cause the Second Surviving Company or the Property Entities to pay any Taxes due with respect to such Tax Returns (other than, for the avoidance of doubt, Taxes with respect to Flow-Through Tax Returns for Tax periods ending on or before the Closing Date) described in this Section 6.10(b) and shall be responsible for any failure to file such Tax Returns and to make such payments.

(c) The Parties shall cooperate fully, as and to the extent reasonably requested by another Party, in connection with the filing of Tax Returns and any audit, litigation, or other proceeding with respect to Taxes relating to the transactions contemplated hereby. Such cooperation shall include the retention and (upon another Party’s request) the provision of records and information that are relevant to any such Tax Return or audit, litigation or other proceeding and making employees or representatives available on a mutually convenient basis to provide additional information and explanation of any material provided under this Agreement.

(d) Notwithstanding anything herein to the contrary, each of the Grey Rock Entities shall make a “push-out” election under Section 6226(a) of the Code (and any corresponding provision of state or local Law) with respect to any imputed underpayment with respect to any Tax period that does not begin on or after the Closing Date, and the Parties and their Affiliates shall take such actions as are necessary to effectuate such election.

(e) The Parties shall not cause ENPC to engage in any transaction or make any election that would result in a liquidation of ENPC for U.S. federal income tax purposes within two years after the Closing Date.

6.11 Transfer Taxes. The Parties do not expect any Transfer Taxes to arise by reason of the consummation of the transactions contemplated by this Agreement. To the extent that any Transfer Taxes are assessed, such Transfer Taxes will be borne by ParentCo other than Taxes as a result of issuing shares in any name other than that of the registered holder of the Company Certificates or ENPC Certificates. The Parties will cooperate in good faith in the filing of any Tax Returns with respect to Transfer Taxes and with respect to minimizing, to the extent permissible under Law, the amount of any Transfer Taxes.

6.12 Tax Reporting. The Parties intend, for U.S. federal income (and applicable state and local) tax purposes, that (a) the First Merger qualifies as a “reorganization” within the meaning of Section 368(a) of the Code to the extent that the applicable requirements are otherwise satisfied, (b) the Mergers taken together qualify (in whole or in part) for nonrecognition of gain or loss pursuant to Sections 351 of the Code, and (c) the ENPC Recapitalization qualifies as a “recapitalization” described in Section 368(a)(1)(E) of the Code. Unless required to do so as a result of a “determination” as defined in Section 1313(a) of the Code, each of the Parties agrees not to make any tax filing or otherwise take any position inconsistent with the Mergers, taken together, qualifying as an exchange of the interests in ENPC and the Company described in Section 351 of the Code (the “Intended Tax Treatment”) and to cooperate with each other Party to make any filings, statements or reports required to effect, disclose or report the Mergers, taken together, as qualifying for the Intended Tax Treatment.

6.13 The Proxy Statement/Prospectus and the Special Meeting.

(a) As promptly as reasonably practicable after the Execution Date, ENPC and the Company will prepare and ENPC and Parentco will file with the SEC a proxy statement and registration statement on Form S-4 with respect to the Transactions and the Redemption Offer (as amended or supplemented from time to time, the “Proxy Statement/Prospectus”) in preliminary form. The ENPC Board Recommendation shall be included in the Proxy Statement/Prospectus. The Proxy Statement/Prospectus shall also include the registration of shares of

55

Parentco Common Stock and Parentco Warrants to be issuable as Aggregate Transaction Consideration and the registration of Parentco Common Stock issuable upon the exercise of any such Parentco Warrants. ENPC shall provide copies of the proposed final form of Proxy Statement/Prospectus to the Company such that the Company and its Representatives are afforded a reasonable amount of time prior to the dissemination or filing thereof to review such materials and comment thereon prior to such dissemination or filing, and ENPC shall consider in good faith any comments of such Persons and shall make ENPC’s Representatives available to discuss such comments with such Persons. ENPC shall provide the Company with copies of any written comments and inform the Company of the material terms of any oral comments that ENPC or Parentco receives from the SEC or its staff with respect to the Proxy Statement/Prospectus promptly after the receipt of such comments and ENPC and the Company shall prepare any proposed written or material oral responses to such comments and ENPC shall give the Company a reasonable opportunity under the circumstances to review and comment on any final form of proposed written or material oral responses to such comments and ENPC shall reasonably consider such comments in good faith. ENPC will cause the Proxy Statement/Prospectus to be transmitted to the holders of ENPC Common Stock and ENPC CAPS^™ as promptly as practicable following the date on which the SEC confirms it has no further comments on the Proxy Statement/Prospectus.

(b) ENPC will take, in accordance with applicable Law, NYSE rules, the rules of any other applicable stock exchange and the Organizational Documents of ENPC, all action necessary to call, hold and convene a special meeting of holders of ENPC Common Stock (including any adjournment or postponement, the “Special Meeting”) to consider and vote upon (i) the Business Combination Proposal, (ii) proposals relating to differences between the First Amended Charter and the certificate of incorporation of ENPC as in effect on the date of the Special Meeting (if required to be approved by ENPC’s stockholders), (iii) a proposal to approve and adopt the LTIP, (iv) such other proposals as reasonably agreed by ENPC and the Company to be necessary or appropriate in connection with the Transactions, and (v) adjournment of the Special Meeting, if necessary, to permit further solicitation of proxies because there are not sufficient votes to approve and adopt any of the foregoing ((i) through (v), collectively, the “Transaction Proposals”) as promptly as reasonably practicable after the filing of the Proxy Statement/Prospectus in definitive form with the SEC. Subject to any adjournment in accordance with this Section 6.13, ENPC will convene and hold the Special Meeting not later than 30 days following the mailing of the Proxy Statement/Prospectus to the holders of ENPC Common Stock. Once the Special Meeting to consider and vote upon the Transaction Proposals has been called and noticed, ENPC will not postpone or adjourn the Special Meeting without the consent of the Company, which consent will not be unreasonably withheld, conditioned or delayed, other than (i) for the absence of a quorum, (ii) to allow reasonable additional time for the filing and mailing of any supplemental or amended disclosure that ENPC has determined in good faith, after consultation with its outside legal advisors, is necessary under applicable Law and for such supplemental or amended disclosure to be disseminated to and reviewed by the holders of ENPC Common Stock prior to the Special Meeting or (iii) an adjournment or postponement of up to 10 Business Days to solicit additional proxies from holders of ENPC Common Stock. Subject to Section 6.13(c), ENPC will take all reasonable lawful action to solicit ENPC Stockholder Approval of the Transaction Proposals. ENPC shall not terminate or withdraw the Redemption Offer, other than in connection with the valid termination of this Agreement or with the prior written consent of the Company.

(c) The ENPC Board will recommend that the holders of ENPC Common Stock approve the Transaction Proposals (the “ENPC Board Recommendation”). Except as provided in the following sentence, the ENPC Board shall not withdraw, amend, qualify or modify the ENPC Board Recommendation (a “Change in Recommendation”). Notwithstanding the foregoing, (x) the ENPC Board may make a Change in Recommendation if it determines in good faith that a failure to make such Change in Recommendation would reasonably be expected to be inconsistent with its fiduciary obligations under applicable Law and (y) nothing in this Agreement shall prevent the ENPC Board from approving the termination of this Agreement in accordance with its terms. For the avoidance of doubt, unless this Agreement is terminated in accordance with its terms, any Change in Recommendation will not (I) change the approval of this Agreement or any other approval of the ENPC Board or (II) relieve ENPC of any of its obligations under this Agreement, including its obligation to hold the Special Meeting.

Each Party and its counsel cooperated in the drafting and preparation of this Agreement and the documents referred to herein, and any and all drafts relating thereto exchanged between the Parties shall be deemed the work product of the Parties and may not be construed against any Party by reason of its preparation. Accordingly, any rule of law or any legal decision that would require interpretation of any ambiguities in this Agreement against any Party that drafted it is of no application and is hereby expressly waived.

64

(b) The inclusion of any information in the Company Disclosure Schedules or the ENPC Disclosure Schedules shall not be deemed an admission or acknowledgment, in and of itself and solely by virtue of the inclusion of such information in the Company Disclosure Schedules or the ENPC Disclosure Schedules, as applicable, that such information is required to be listed in the Company Disclosure Schedules or the ENPC Disclosure Schedules, as applicable, that such items are material to any Party or any of its Subsidiaries taken as a whole, or that such items have resulted in a Company Material Adverse Effect or ENPC Material Adverse Effect. The headings, if any, of the individual sections of each of the Company Disclosure Schedules and the ENPC Disclosure Schedules are inserted for convenience only and shall not be deemed to constitute a part thereof or a part of this Agreement. The Company Disclosure Schedules and the ENPC Disclosure Schedules are arranged in sections corresponding to the Sections of this Agreement merely for convenience, and the disclosure of an item in one section of the Company Disclosure Schedules or the ENPC Disclosure Schedules as an exception to a particular representation or warranty shall be deemed adequately disclosed as an exception with respect to all other representations or warranties to the extent that the relevance of such item to such representations or warranties is readily apparent from such item, notwithstanding the presence or absence of an appropriate section of the Company Disclosure Schedules or the ENPC Disclosure Schedules with respect to such other representations or warranties or an appropriate cross-reference thereto.

(c) The specification of any dollar amount in the representations and warranties or otherwise in this Agreement or in the Company Disclosure Schedules or the ENPC Disclosure Schedules is not intended and shall not be deemed to be an admission or acknowledgment of the materiality of such amounts or items, nor shall the same be used in any dispute or controversy between the Parties to determine whether any obligation, item or matter (whether or not described herein or included in any schedule) is or is not material for purposes of this Agreement.

(d) All references in this Agreement to Exhibits, Schedules, Articles, Sections, subsections and other subdivisions refer to the corresponding Exhibits, Schedules, Articles, Sections, subsections and other subdivisions of this Agreement unless expressly provided otherwise. Titles appearing at the beginning of any Articles, Sections, subsections or other subdivisions of this Agreement are for convenience only, do not constitute any part of such Articles, Sections, subsections or other subdivisions, and shall be disregarded in construing the language contained therein. The words “this Agreement,” “herein,” “hereby,” “hereunder” and “hereof” and words of similar import, refer to this Agreement as a whole and not to any particular subdivision unless expressly so limited. The words “this Section,” “this subsection” and words of similar import, refer only to the Sections or subsections hereof in which such words occur. The word “including” (in its various forms) means “including, without limitation.” The word “or” is not exclusive unless the context otherwise requires. Pronouns in masculine, feminine or neuter genders shall be construed to state and include any other gender and words, terms and titles (including terms defined herein) in the singular form shall be construed to include the plural and vice versa, unless the context otherwise expressly requires. Unless the context otherwise requires, all defined terms contained herein shall include the singular and plural and the conjunctive and disjunctive forms of such defined terms. Unless the context otherwise requires, all references to a specific time shall refer to Dallas, Texas time.

(e) In this Agreement, except as the context may otherwise require, references to: (i) any agreement (including this Agreement), contract, statute or regulation are to the agreement, contract, statute or regulation as amended, modified, supplemented, restated or replaced from time to time (in the case of an agreement or contract, to the extent permitted by the terms thereof and, if applicable, by the terms of this Agreement); (ii) any Governmental Entity include any successor to that Governmental Entity; (iii) any applicable Law refers to such applicable Law as amended, modified, supplemented or replaced from time to time (and, in the case of statutes, include any rules and regulations promulgated under such statute) and references to any section of any applicable Law or other law include any successor to such section; and (iv) “days” means calendar days.

This Agreement (together with the Transaction Agreements and any other documents and instruments executed pursuant to this Agreement) and the Non-Disclosure Agreement dated as of March 16, 2022 by and between ENPC and Grey Rock Energy Management, LLC (the “Confidentiality Agreement”), constitute the entire agreement and supersedes all prior agreements and understandings, both written and oral, among the Parties or any of their respective Affiliates with respect to the subject matter hereof. Except for the provisions of Sections 6.6, 6.20, 9.10 and 9.15 (which from and after the Closing are intended for the benefit of, and shall be enforceable by, the Persons referred to therein and by their respective heirs and representatives), nothing in this Agreement, express or implied, is intended to or shall confer upon any Person other than the Parties any right, benefit or remedy of any nature whatsoever under or by reason of this Agreement.

9.7 Governing Law; Venue; Waiver of Jury Trial.

(a) THIS AGREEMENT, AND ALL CLAIMS OR CAUSES OF ACTION (WHETHER IN CONTRACT OR TORT) THAT MAY BE BASED UPON, ARISE OUT OF RELATE TO THIS AGREEMENT, OR THE NEGOTIATION, EXECUTION OR PERFORMANCE OF THIS AGREEMENT, SHALL BE GOVERNED BY AND CONSTRUED IN ACCORDANCE WITH THE LAWS OF THE STATE OF DELAWARE, WITHOUT GIVING EFFECT TO THE PRINCIPLES OF CONFLICTS OF LAW THEREOF.

(b) THE PARTIES IRREVOCABLY SUBMIT TO THE JURISDICTION OF THE COURT OF CHANCERY OF THE STATE OF DELAWARE (OR, IF THE COURT OF CHANCERY OF THE STATE OF DELAWARE OR THE DELAWARE SUPREME COURT DETERMINES THAT THE COURT OF CHANCERY DOES NOT HAVE OR SHOULD NOT EXERCISE SUBJECT MATTER JURISDICTION OVER SUCH MATTER, THE SUPERIOR COURT OF THE STATE OF DELAWARE) AND THE FEDERAL COURTS OF THE UNITED STATES OF AMERICA LOCATED IN THE STATE OF DELAWARE SOLELY IN CONNECTION WITH ANY DISPUTE THAT ARISES IN RESPECT OF THE INTERPRETATION AND ENFORCEMENT OF THE PROVISIONS OF THIS AGREEMENT AND THE DOCUMENTS REFERRED TO IN THIS AGREEMENT OR IN RESPECT OF THE TRANSACTIONS CONTEMPLATED HEREBY, AND HEREBY WAIVE, AND AGREE NOT TO ASSERT, AS A DEFENSE IN ANY ACTION, SUIT OR PROCEEDING FOR INTERPRETATION OR ENFORCEMENT HEREOF OR ANY SUCH DOCUMENT THAT IT IS NOT SUBJECT THERETO OR THAT SUCH ACTION, SUIT OR PROCEEDING MAY NOT BE BROUGHT OR IS NOT MAINTAINABLE IN SAID COURTS OR THAT VENUE THEREOF MAY NOT BE APPROPRIATE OR THAT THIS AGREEMENT OR ANY SUCH DOCUMENT MAY NOT BE ENFORCED IN OR BY SUCH COURTS, AND THE PARTIES IRREVOCABLY AGREE THAT ALL CLAIMS WITH RESPECT TO SUCH ACTION, SUIT OR PROCEEDING SHALL BE HEARD AND DETERMINED EXCLUSIVELY BY SUCH A DELAWARE FEDERAL OR STATE COURT. THE PARTIES HEREBY CONSENT TO AND GRANT ANY SUCH COURT JURISDICTION OVER THE PERSON OF SUCH PARTIES AND OVER THE SUBJECT MATTER OF SUCH DISPUTE AND AGREE THAT MAILING OF PROCESS OR OTHER PAPERS IN CONNECTION WITH SUCH ACTION, SUIT OR PROCEEDING IN THE MANNER PROVIDED IN SECTION 9.3 OR IN SUCH OTHER MANNER AS MAY BE PERMITTED BY LAW SHALL BE VALID AND SUFFICIENT SERVICE THEREOF.

(c) EACH PARTY ACKNOWLEDGES AND AGREES THAT ANY CONTROVERSY WHICH MAY ARISE UNDER THIS AGREEMENT IS LIKELY TO INVOLVE COMPLICATED AND DIFFICULT ISSUES, AND THEREFORE EACH SUCH PARTY HEREBY IRREVOCABLY AND UNCONDITIONALLY WAIVES ANY RIGHT SUCH PARTY MAY HAVE TO A TRIAL BY JURY IN RESPECT OF ANY LITIGATION DIRECTLY OR INDIRECTLY ARISING OUT OF OR RELATING TO THIS AGREEMENT OR THE TRANSACTIONS CONTEMPLATED BY THIS AGREEMENT. EACH PARTY CERTIFIES AND ACKNOWLEDGES THAT (I) NO REPRESENTATIVE, AGENT OR ATTORNEY OF ANY OTHER PARTY HAS REPRESENTED, EXPRESSLY OR OTHERWISE, THAT SUCH OTHER PARTY WOULD NOT, IN THE EVENT OF LITIGATION, SEEK TO ENFORCE THE FOREGOING WAIVER; (II) SUCH PARTY

66

UNDERSTANDS AND HAS CONSIDERED THE IMPLICATIONS OF THE FOREGOING WAIVER; (III) SUCH PARTY MAKES THE FOREGOING WAIVER VOLUNTARILY; AND (IV) SUCH PARTY HAS BEEN INDUCED TO ENTER INTO THIS AGREEMENT BY, AMONG OTHER THINGS, THE MUTUAL WAIVER AND CERTIFICATIONS IN THIS SECTION 9.7.

Each Party agrees that, should any court or other competent Governmental Entity hold any provision of this Agreement or part hereof to be invalid, illegal or unenforceable in any jurisdiction, such invalidity, illegality or unenforceability shall not affect any other term or provision of this Agreement or invalidate or render unenforceable such other term or provision in any other jurisdiction. Upon such determination that any term or other provision is invalid, illegal or unenforceable, the Parties to this Agreement shall negotiate in good faith to modify this Agreement so as to effect the original intent of the Parties as closely as possible in a mutually acceptable manner in order that the transactions contemplated hereby be consummated as originally contemplated to the greatest extent possible. Except as otherwise contemplated by this Agreement, in response to an order from a court or other competent Governmental Entity for any Party to take any action inconsistent herewith or not to take an action consistent herewith or required hereby, to the extent that a Party to this Agreement took an action inconsistent with this Agreement or failed to take action consistent with this Agreement or required by this Agreement pursuant to such order, such Party shall not incur any liability or obligation unless such Party did not in good faith seek to resist or object to the imposition or entering of such order.

9.9 Assignment. Neither this Agreement nor any of the rights, interests or obligations hereunder may be assigned by any Party (whether by operation of law or otherwise) without the prior written consent of all the other Parties. Subject to the preceding sentence, this Agreement will be binding upon, inure to the benefit of and be enforceable by the Parties and their respective successors and assigns. Any purported assignment in violation of this Section 9.9 shall be void.

9.10 Affiliate Liability. No Affiliate or Representative of a Party or Representative of an Affiliate of a Party shall have any liability or obligation in its capacity as such to any other Party hereunder of any nature whatsoever in connection with or under this Agreement or the transactions contemplated hereby (except, for the avoidance of doubt, to the extent that such Affiliate or Representative executes this Agreement or any other agreement, certificate or instrument as a principal intending to be legally bound thereby), and each Party hereby waives and releases all claims of any such liability and obligation.

9.11 Specific Performance. The Parties agree that irreparable damage would occur in the event that any of the provisions of this Agreement were not performed in accordance with its specific terms or were otherwise breached. Each Party agrees that, in the event of any breach or threatened breach by any other Party of any covenant or obligation contained in this Agreement, the 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 (on behalf of itself and the third Party beneficiaries of this Agreement) (a) a decree or order of specific performance to enforce the observance and performance of such covenant or obligation and (b) an injunction restraining such breach or threatened breach. Each Party further agrees that no other Party to this Agreement 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 9.11, and each Party to this Agreement irrevocably waives any right it may have to require the obtaining, furnishing or posting of any such bond or similar instrument.

9.12 Amendment. This Agreement may not be amended except by an instrument in writing signed on behalf of each of the Parties. Once ENPC Stockholder Approval is received, the Parties agree that no amendment or modification may be made to this Agreement that would, by Law, require another vote of the stockholders of ENPC without first obtaining the approval of ENPC’s requisite stockholders.

67

9.13 Extension; Waiver. At any time prior to the Closing, ENPC and the Company may, to the extent legally allowed (provided, that ENPC may not take any action pursuant to this Section 9.13 with respect to another Parent Party without the consent of the Company):

(a) extend the time for the performance of any of the obligations or acts of the other Parties hereunder;

(b) waive any inaccuracies in the representations and warranties of the other Parties contained herein or in any document delivered pursuant to this Agreement; or

(c) waive compliance with any of the agreements or conditions of the other Parties contained herein.

Notwithstanding the foregoing, no failure or delay by any Party in exercising any right hereunder shall operate as a waiver thereof nor shall any single or partial exercise thereof preclude any other or further exercise of any other right hereunder. No agreement on the part of a Party to this Agreement to any such extension or waiver shall be effective or enforceable unless set forth in an instrument in writing signed on behalf of such Party.

9.14 Trust Account Waiver. The Company acknowledges that ENPC is a blank check company with the powers and privileges to effect a Partnering Transaction (as defined in ENPC’s Organizational Documents). The Company further acknowledges that substantially all of ENPC’s assets consist of the cash proceeds of ENPC’s initial public offering and private placements of its securities and substantially all of those proceeds have been deposited in the Trust Account for the benefit of ENPC, certain of its public stockholders and the underwriters of ENPC’s initial public offering. For and in consideration of the Parent Parties entering into this Agreement, the Company hereby irrevocably waives any right, title, interest or claim of any kind it has or may have in the future in or to any monies in the Trust Account and agrees not to seek recourse against the Trust Account or any funds distributed therefrom as a result of, or arising out of, this Agreement and any negotiations, contracts or agreements with any Parent Party; provided that (a) nothing herein shall serve to limit or prohibit the Company’s right to pursue a claim against any Parent Party pursuant to this Agreement for legal relief against monies or other assets of any Parent Party held outside the Trust Account or, subject to Section 9.11, for specific performance or other equitable relief in connection with the transactions contemplated hereby or for fraud and (b) nothing herein shall serve to limit or prohibit any claims that the Company may have in the future pursuant to this Agreement against the assets or funds of any Party to this Agreement or any of their respective Subsidiaries that are, in each case, not held in the Trust Account.

9.15 Releases.

(a) The Company hereby waives, acquits, forever discharges and releases, effective as of the Closing, on behalf of itself and each of its Controlled Affiliates (other than the Property Entities) and each of their respective past, present and future stockholders, partners, members and Representatives and each of their respective successors and assigns (collectively, its “Related Persons”), to the fullest extent permitted by Law, any and all causes of action, damages, judgments, liabilities and rights against the Parent Parties, Sponsor, Solamere Capital, LLC, and each of their respective Subsidiaries and past, present and future equityholders, Affiliates and Representatives (collectively, the “ENPC Related Persons”), whether absolute or contingent, liquidated or unliquidated, known or unknown, determined, determinable or otherwise, that the Company or any of its Related Persons has ever had or may now or hereafter have to the extent, and only to the extent, arising from facts, occurrences or circumstances existing at or prior to the Closing, in each case, relating to the Grey Rock Entities or their respective businesses, arising from or relating to this Agreement or otherwise, whether in law or in equity, in contract, in tort or otherwise, in any capacity, including any claims to any additional Interests in any Parent Party or any of their respective Subsidiaries or any distributions or payments (as consideration of services or otherwise) from any Parent Party or any of their respective Subsidiaries by reason of any matter, cause or thing whatsoever other than (i) the applicable Surviving Provisions, (ii) any obligations owed to any officer, director, manager, employee or consultant pursuant to the Organizational Documents of any of the Grey Rock

The Company agrees not to, and to cause its Related Persons not to, assert any Proceeding against any Parent Party, ENPC Related Person or Grey Rock Entity with respect to Company Released Claims. The Company agrees that it will not (and will not cause or permit any of its Related Persons to) exercise or assert any right of contribution, set-off or indemnity or any other right or remedy (including any such rights and remedies contained in the Organizational Documents of the Grey Rock Entities) against any Parent Party, ENPC Related Person or Grey Rock Entity in connection with any liability for any Company Released Claim. Notwithstanding anything herein to the contrary, this Section 9.15(a) shall not impose any restrictions or limitations on the ability of the Company (or any of its Related Persons) to exercise or assert any rights or remedies against any Parent Party, ENPC Related Person or Grey Rock Entity that may arise as a result of the ownership by the Company or its Related Persons of any Interests in any Parent Party, ENPC Related Person or Grey Rock Entity from and after the Closing.
