(c)violate or result in a breach of any Law applicable to Buyer, except for such violations or breaches as would not be material; or

(d)require any consent or approval of any Governmental Authority under any Law applicable to Buyer, other than immaterial consents or approvals.

5.5Acquisition as Investment. Buyer is acquiring the Interests for its own account as an investment without the present intent to sell, transfer or otherwise distribute the same to any other Person in violation of any state or federal securities laws. Buyer has made, independently

Buyer has conducted its own independent review and analysis of the Business and of the Assets, liabilities, results of operations, financial condition, technology and prospects of the Companies and acknowledges that Buyer has been provided access to personnel, properties, premises and records of the Companies for such purpose. In entering into this Agreement, Buyer has relied solely upon the representations, warranties and covenants contained herein and upon its own investigation and analysis of the Companies and the Business (such investigation and analysis having been performed by Buyer), and Buyer:

(a)absent Actual Fraud, acknowledges and agrees that it has not been induced by and has not relied upon any Due Diligence Information, representations, warranties or statements, whether oral or written, express or implied, made by Seller, the Companies or any of their Representatives, Affiliates or agents except for the representations and warranties expressly set forth in this Agreement and those items delivered to Buyer pursuant to Section 2.4 and Section 7.4;

5.8Broker’s Commissions. Buyer has not, directly or indirectly, entered into any Contract with any Person that would obligate Seller or any of its Affiliates to pay any commission, brokerage fee or “finder’s fee” in connection with the transactions contemplated herein.

5.9Solvency. Immediately after giving effect to the transactions contemplated by this Agreement, assuming the accuracy of the representations and warranties set forth in Article III, none of Buyer or the Companies, individually or in the aggregate, will (a) be insolvent (either because its financial condition is such that the sum of its debts is greater than the fair value of its assets or because the fair salable value of its assets is less than the amount required to pay its probable liability on its existing debts as they mature), (b) have unreasonably small capital with which to engage in its business or (c) have incurred debts beyond its ability to pay as they become due. In completing the transactions contemplated by this Agreement, Buyer does not intend to hinder, delay or defraud any present or future creditors of any of the Companies.

(a)Except as required or permitted hereby, or as consented to by Buyer (which consent shall not be unreasonably withheld, conditioned or delayed), or as otherwise set forth in Schedule 6.1, from the date of this Agreement until the earlier of the Closing or the termination of this Agreement in accordance with the terms hereof (the “Interim Period”), Seller will use commercially reasonable efforts to cause each Company (x) to operate in the ordinary course of business; and (y) to preserve intact its material relationships with third parties. Without limiting the foregoing, except as otherwise required or permitted hereby or required by the terms of any material Permit or any Material Contract, Seller will cause each Company not to undertake any of the following during the Interim Period without the consent of Buyer (which consent shall not be unreasonably withheld, conditioned or delayed):

(iii)sell, transfer or otherwise dispose of any material Assets of such Company, other than (A) sales of inventory in the ordinary course of business, (B) any abandonment of Intellectual Property Rights that such Company determines in the exercise of its reasonable business judgment to abandon in the ordinary course of business,

(v)transfer, issue, sell or otherwise dispose, or repurchase, redeem or otherwise acquire, any Equity Interests in such Company;

(vi)liquidate, dissolve, recapitalize, reorganize or otherwise wind up all or any portion of the Business;

(viii)other than in the ordinary course of business, terminate, renew, amend, restate, supplement or waive any material rights under any Material Contract involving total consideration throughout its term in excess of $100,000;

(ix)enter into any Contract that would have been a Material Contract had it been entered into prior to the date of this Agreement;

(x)make any loans, advances or capital contributions to, or investments in, any other Person;

(xi)incur (or enter into any agreement for the incurrence of) any Indebtedness (except for Indebtedness entered into in the ordinary course of business);

(xii)cause the Assets of the Companies or any Equity Interests in the Company to be encumbered by any Liens, except for Permitted Liens;

(xiii)incur any capital expenditures or operating expenditures other than in the ordinary course of business consistent with past practice and not to exceed, individually or in the aggregate, $100,000;

(xiv)cancel or compromise any debt or claim or waive or release any material right of such Company that could be reasonably expected (due to the nature of the claims involved or the scope of their applicability to such Company’s business or operations) to involve amounts of $100,000 or more in value;

(xv)settle or compromise any action, suit, investigation or proceeding against such Company that could be reasonably expected (due to the nature of the claims involved or the scope of their applicability to such Company’s business or operations) to involve amounts of $100,000 or more in value, except for any cases in which the amount paid in settlement does not exceed the amount reserved against such matter in the Financial Statements (or the notes thereto);

(xvi)enter into or modify in any material respect, terminate, cancel, renew or assign any Permit, or make any regulatory filing that is not either expressly contemplated by this Agreement or made in the ordinary course of business;

(xvii)except as may be required to meet the requirements of applicable Law or GAAP, change any accounting method or practice in a manner that is inconsistent with past practice in a way that would materially and adversely affect such Company; or

Notwithstanding the foregoing, each Company may take commercially reasonable actions with respect to (i) emergency situations or (ii) requirements of Law, and each Company shall promptly inform Buyer of any such actions taken outside the ordinary course of business. For the avoidance of doubt, and notwithstanding anything in this Agreement to the contrary, nothing in this Agreement shall prohibit or otherwise restrict in any way the operation of the business of Summit Parent and its Affiliates (including any actions that may be outside the ordinary course of business of Summit Parent) so long as the Business is not materially and disproportionately affected by any such action as compared to the other businesses of Summit Parent.

(a)During the Interim Period, Seller will provide (or will cause each Company to provide) Buyer and its Representatives with reasonable access, upon reasonable prior notice and during normal business hours, to the Assets of such Company and the officers and employees of such Company (or, as appropriate, its Affiliates) who have significant responsibility for the Assets of such Company, but only to the extent that such access (i) does not unreasonably interfere with the Business or the safe commercial operations of the Assets of such Company (or, as appropriate, its Affiliates) and (ii) is reasonably related to Buyer’s obligations and rights hereunder; provided, however, that (A) Seller shall have the right to have a Representative present for any communication with employees or officers of such Company or its Affiliates, (B) Buyer shall and shall cause its Representatives to observe and comply with all generally applicable health, safety and security requirements of such Company and (C) Buyer shall not conduct any environmental sampling or testing, except for the completion of a Phase I environmental review, or otherwise make direct contact identifying the Company with regulators of such Company, without receiving the prior written consent of the Seller; provided, however, Buyer shall be permitted to contact the New Mexico State Land Office and Bureau of Land Management after reasonable prior notice to and consultation with Seller, such notice to include a general description of the matters Buyer desires to discuss and address with the New Mexico State Land Office and Bureau of Land Management. Buyer shall hold in confidence all such information on the terms and subject to the conditions contained in Section 6.11. Notwithstanding the foregoing, Buyer shall have no right of access to, and none of the Companies, Seller nor any of their respective Affiliates shall have any obligation to provide any information, the disclosure of which (1) would reasonably be expected in the opinion of counsel to jeopardize any privilege available to Seller, the Companies or any of their respective Affiliates, (2) would cause Seller, the Companies or any of their respective Affiliates to breach a Material Contract or express confidentiality obligation, or (3) would result in a violation of Law.

(b)Buyer understands that Seller has had discussions regarding a potential sale of the Interests and the preparation and negotiation of this Agreement, the Schedules hereto and the other documents contemplated herein, and that, (x) except to the extent discovery rules would otherwise permit review of such information by Buyer or the Companies if such information were in the possession of Seller,(y) except in the case of any allegation of fraud and (z) excluding information related to this Agreement (including the representations and warranties and covenants set forth herein and the Schedules and Exhibits attached hereto), (i) Buyer and the Companies shall not be entitled to use in connection with any disputes against Seller or the Companies (before or after Closing) any of Seller’s or the Companies’ internal drafts of this Agreement or emails or other written information (including in electronic form) relating to any potential sales process involving the Interests, and (ii) Buyer hereby agrees that (A) it shall not have any rights to any such information and (B) it shall not request any of the Companies, its Affiliates or any of their respective Representatives to provide to it any such information.

(c)During the Interim Period and for ninety (90) days following the Closing Date, the Buyer agrees to indemnify and hold harmless Seller and the Companies, any of their respective Affiliates and their respective Representatives for any and all liabilities, losses, costs or expenses incurred by Seller or the Companies, any of their respective Affiliates or their respective Representatives arising out of the access rights under this Section 6.2, including any Claims by any of Buyer’s Representatives for any injuries or property damage while accessing any Assets; provided, however, THIS INDEMNITY SHALL NOT APPLY TO ANY SUCH DAMAGE, INJURY, SICKNESS OR DEATH WHICH WAS CAUSED OR CONTRIBUTED TO BY THE GROSS NEGLIGENCE OR WILLFUL MISCONDUCT OF SELLER AND SELLER’S REPRESENTATIVES.

(a)Each of Seller and Buyer shall use commercially reasonable efforts to obtain as promptly as practicable all consents and approvals that Seller or Buyer is required to obtain in order to consummate the transactions contemplated hereby by the date that is 30 days after the date hereof; provided that for purposes of clarification, the obtaining of such consents and approvals shall not be a condition to Closing except to the extent expressly set forth in Section 2.4.

(b)In connection with any such filings, each of Seller and Buyer shall use commercially reasonable efforts to undertake promptly any and all actions required to complete lawfully the transactions contemplated by this Agreement prior to the date that is 30 days after the date hereof.

(c)Each of Seller and Buyer shall provide prompt notification to the other when it becomes aware that any consent or approval referred to in this Section 6.3 is obtained, taken, made, given or denied, as applicable.

6.4Resignation and Removal. Notwithstanding anything in this Agreement to the contrary, at or prior to the Closing, Seller shall cause or accept the resignation or removal of any manager, partner, officer and/or director, as applicable, nominated or appointed by Seller or its Affiliates to any board or operating, management or other committee of each Company.

(b)Seller will, or will cause the Companies to, deliver reasonable and customary evidence demonstrating the release of all Liens for Indebtedness of the Companies on the Assets of the Companies (other than Permitted Liens);

(c)Seller will cause, any accounts payable and/or accounts receivable between any Company, on the one hand, and a Non-Company Affiliate, on the other hand, to be paid in full; and

(d)Seller may cause the Companies to pay cash dividends and/or cash distributions to Seller or its Affiliates.

(i)Seller shall prepare or cause to be prepared and file or cause to be filed a 2022 Form 1065, U.S. Return of Partnership Income, of which Summit Parent is the primary filer, which report shall include all items and activities of the Companies through and including the Closing Date.

(ii)Seller shall prepare or cause to be prepared any Tax Return of any Company required to be filed after the Closing Date (other than the Tax Return set forth in Section 6.6(a)(i)) for all Tax periods ending on or before the Closing Date. Such Tax Returns shall be prepared on a basis consistent with the past practice of Seller and the Companies except to the extent otherwise required by applicable Law. Reasonably in advance of the due date for the filing of any such Tax Return, Seller shall deliver a draft of such Tax Return, together with all supporting documentation and workpapers, to Buyer for its review and reasonable comment. Seller will (x) cause such Tax Return (as revised to incorporate Buyer’s reasonable comments) to be timely filed and will provide a copy thereof to Seller, and (y) timely pay the Taxes shown due thereon.

(iii)Buyer shall prepare or cause to be prepared any Tax Return of any Company for any Straddle Periods. Such Tax Returns shall be prepared on a basis consistent with the past practice of the Seller and the Companies except to the extent otherwise required by applicable Law. Reasonably in advance of the due date for the filing of any such Tax Return, Buyer shall deliver a draft of such Tax Return, together with all supporting documentation and workpapers, to Seller for its review and reasonable comment. Buyer will (x) cause such Tax Return (as revised to incorporate Seller’s reasonable comments) to be timely filed and will provide a copy thereof to Seller, and (y) timely pay the Taxes shown due thereon.

(i)Taxes that are either (A) based upon or related to income or receipts, or (B) imposed in connection with any sale or other transfer or assignment of property (real or personal, tangible or intangible), shall be allocated between the portion of such Straddle Period ending immediately prior to the Closing Date and the portion of such Straddle Period beginning on the Closing Date on a “closing of the books” basis by assuming the books of the Companies were closed at the end of the Closing Date; provided that exemptions, allowances or deductions that are calculated on an annual basis (including depreciation and amortization deductions) shall be allocated between the portion of such Straddle Period ending at the end of the Closing Date and the portion of such Straddle Period beginning on the Closing Date in proportion to the number of days in each period.

(ii)Taxes that are imposed on a periodic basis with respect to the assets of the Companies shall be allocated between the portion of such Straddle Period ending immediately prior to the Closing Date and the portion of such Straddle Period beginning on the Closing Date by prorating each such Tax based on the number of days in the applicable Straddle Period that occur before the Closing Date, on the one hand, and the number of days in such Straddle Period that occur on and after the Closing Date, on the other hand. Consistent with the foregoing, the amount of such Taxes that is allocable to the portion of the Straddle Period (1) ending immediately prior to the Closing Date shall be deemed to be the amount of such Taxes for the entire Straddle Period multiplied by a fraction the numerator of which is the number of calendar days in the portion of the Straddle Period ending immediately prior to the Closing Date, and the denominator of which is the number of calendar days in the entire Straddle Period, and (2) beginning on the Closing Date shall be deemed to be the amount of such Taxes for the entire Straddle Period multiplied by a fraction the numerator of which is the number of calendar days from (and including) the Closing Date through the end of the Straddle Period, and the denominator of which is the number of calendar days in the entire Straddle Period. Such proration shall, initially, be based on the most recent Tax statements, received by the Seller as of the Closing Date. Following the Closing Date, each party shall, upon request of the other party, immediately reimburse the other party for any such Taxes for which said party is responsible but have been paid by the other party.

(c)Transfer Taxes. Buyer shall bear and pay all transfer, sales, use, stamp, registration or other similar Taxes and any documentary, filing or recording fees resulting from the transfer of the Interests to Buyer pursuant to this Agreement (“Transfer Taxes”). Buyer and Seller shall cooperate in good faith to minimize, to the extent permissible under applicable Law, the amount of any such Transfer Taxes.

(d)Cooperation. Buyer and Seller shall cooperate fully as and to the extent reasonably requested by the other Party, in connection with the filing of Tax Returns and any audit, litigation or other proceeding with respect to Taxes imposed on or with respect to the assets, operations or activities of the Companies (each a “Tax Proceeding”). Such cooperation shall include the retention and (upon the other Party’s request) the provision of records and information which are reasonably relevant to any such Tax Return or Tax Proceeding and making employees available on a mutually convenient basis to provide additional information and explanation of any material provided hereunder.

(e)Amended Tax Returns. No amended Tax Return with respect to a Pre- Closing Period or Straddle Period shall be filed by or on behalf of any Company without the prior written consent of Seller.

(i)Seller shall prepare or cause to be prepared an allocation schedule (the “Allocation Schedule”), allocating the Purchase Price (plus any other items that are properly treated as consideration for U.S. federal income Tax purposes) among the Companies’ assets in a manner consistent with Section 1060 of the Code. Seller shall deliver the Allocation Schedule to Buyer within 120 days after the Closing Date for Buyer’s review and reasonable comments. Within 30 days after receiving such Allocation Schedule, Buyer shall notify Seller in writing if Buyer has any objections to the allocations on the Allocation Schedule and shall specify the basis for any such objections. If Buyer does not notify Seller of any objection to the Allocation Schedule, then it shall be deemed agreed to by Seller and Buyer and the Allocation Schedule shall be final and binding. If Buyer objects to any allocations on the Allocation Schedule, then Seller and Buyer shall negotiate in good faith to resolve any disagreement regarding the Allocation Schedule as soon as practicable (taking into account the due date of any Tax Returns on which the allocation set forth in the Allocation Schedule is required to be reflected) and memorialize the agreed allocation in a final Allocation Schedule, which shall be final and binding. If Buyer and Seller working in good faith are unable to agree on such disputed items on or prior to the 15th day following the date Buyer provides notice to Seller of any objections to the Allocation Schedule, then either Party may refer such dispute to PricewaterhouseCoopers LLP or, if that firm declines to act as provided in this Section 6.6(f), another firm of independent public accountants, mutually acceptable to Buyer and Seller, which firm shall make a final and binding determination as to all matters in dispute on a timely basis and promptly shall notify the Parties in writing of its resolution. Such accounting firm handling the dispute resolution shall not have the power to modify or amend any term or provision of this Agreement. The costs of such review and report shall be borne by Buyer, on the one hand, and the Seller, on the other hand, in proportion to the aggregate dollar amounts of such dispute(s) resolved in favor of the Buyer compared to the aggregate dollar amounts of such dispute(s) resolved in favor of the Seller (as determined by the accounting firm). The final Allocation Schedule shall be revised to take into account subsequent adjustments to the Purchase Price, in accordance with the provisions of Section 1060 of the Code and the Treasury Regulations thereunder.

(ii)Buyer and Seller shall file all Tax Returns for Tax purposes consistent with the Allocation Schedule, as adjusted. None of Buyer, Seller, the Companies or their respective Affiliates shall take any position on any filed Tax Return that is inconsistent with the Allocation Schedule unless required to do so by applicable Law. If any Governmental Authority disputes the allocation set forth in the Allocation Schedule, the Party receiving notice of the dispute shall promptly notify the other Party of such dispute. Notwithstanding anything in this Section 6.6(f) to the contrary, neither Party shall be unreasonably impeded in its ability and discretion to negotiate, compromise and/or settle any Tax audit, claim or similar proceedings in connection with such Allocation Schedule.

6.7Public Announcements. The Parties will maintain the confidentiality of this Agreement and its terms except that any Party may disclose this Agreement or any of its terms to any of the following if advised of the confidentiality obligations of such information: (a) any direct and indirect holders of Equity Interests in such Party or any Affiliate of such Party and (b) any potential lender to such Party. No Party hereto shall issue any press release or make any public statement with respect to this Agreement or the transactions contemplated hereby without the prior written consent of Buyer and Seller (such consent not to be unreasonably withheld, conditioned or delayed); provided, however, that the foregoing shall not restrict disclosures (i) to the extent required (upon advice of counsel) by applicable Law or regulations or the applicable rules of any stock exchange having jurisdiction over the Parties or their respective Affiliates, or (ii) made by either Party without reference to the other Party or any of the material terms of this Agreement or the transactions contemplated hereby.

6.8Removal of Name. Effective immediately after the Closing, Buyer shall change the name of each Company so as not to include “Summit” or any variants thereof and shall provide evidence thereof to Seller. As promptly as practicable, but in any case within 60 days after the Closing Date, Buyer shall take all commercially reasonable steps to eliminate the name “Summit” and any variants thereof from the Assets of each Company, and, except with respect to such grace period for eliminating existing usage, shall have no right to use any logos, trademarks or trade names belonging to Seller or any of its Affiliates.

6.9Further Assurances. Subject to the terms and conditions of this Agreement, at any time or from time to time after the Closing, at any Party’s request and without further consideration, the other Party shall (and in the case of Buyer, Buyer shall and shall cause the Companies, as applicable, to) execute and deliver to such Party such other instruments of sale, transfer, conveyance, assignment and confirmation, provide such materials and information and take such other actions as such Party may reasonably request in order to consummate the transactions contemplated by this Agreement.

6.10R&W Policy. As of the date hereof, Buyer has obtained and conditionally bound the R&W Policy, which policy expressly provides that (a) the insurer(s) issuing such policy have waived or otherwise shall not pursue any subrogation, contribution or other rights against Seller or any of its Affiliates and/or any of their respective past, present or future Representatives, except in the case of Actual Fraud by Seller, and (b) each of Seller, its Affiliates, and their respective past, present or future Representatives may rely upon and enforce such waiver of subrogation, contribution and other rights as express third party beneficiaries of such waiver of subrogation, contribution and other rights provisions. The aggregate amount of the premium with respect to the R&W Policy, together with the related underwriting fees, due diligence fees, net brokerage fees, premium Taxes and any other fees of the insurer relating to the R&W Policy shall, in the aggregate, be paid 50% by Buyer, on the one hand, and 50% by Seller, on the other hand, with such amounts being paid by the Parties when such payments are due under the R&W Policy and under the engagement letter with AON Risk Services Northeast, Inc. related to is insurance brokerage services. From and after inception of the R&W Policy, unless terminated in its entirety, Buyer shall not (and shall cause its Affiliates not to) amend, modify, or otherwise change, terminate, or waive any provision of the R&W Policy in a manner materially adverse to Seller, any of its Affiliates or any of their respective Representatives, including any rights of the insurer to subrogate or seek recovery from Seller, any of Seller’s Affiliates or any of Seller’s Representatives.

6.11Confidentiality. For a period of two years after Closing, Seller shall, and shall cause its Affiliates (excluding, for the avoidance of doubt, Buyer and the Companies) and direct its Representatives to, treat as confidential and not disclose or otherwise use (including for competitive purposes) any and all Confidential Material except (a) for use under this Agreement or as otherwise agreed to in writing by Buyer, (b) for disclosures to any Governmental Authority having jurisdiction to require disclosure or to any arbitral body or in connection with any routine audit, supervisory examination, regulatory sweep or other regulatory inquiry to the extent required by same, (c) as otherwise may be required by Law, (d) for disclosures during the course of litigation or in connection with enforcing any rights under this Agreement or any Transaction Document, (e) as required for internal audit, financial and tax purposes, or (f) for disclosures to its Representatives in the ordinary course of business.

6.12No Shop. During the Interim Period, the Seller shall not, and shall cause the Companies and their respective Affiliates and the directors, officers, employees, managers, members, agents, advisors or other Representatives to not, solicit, entertain or accept any offer to purchase, or make any offer to sell the Companies. Furthermore, during the Interim Period, Seller shall, and shall cause the Companies and their respective Affiliates and Representatives to, deal exclusively with the Buyer, its Affiliates and their Representatives with respect to the transactions contemplated by this Agreement. The Seller shall not, and shall cause the Companies and their respective Affiliates and Representatives to not, directly or indirectly, facilitate, encourage, solicit or entertain offers or inquiries from, participate in negotiations or discussions with, enter into any agreement or letter of intent with, or disclose any non-public information to, any other person or entity, in each case, with respect to the transactions contemplated by this Agreement, any sale of the Companies, merger or similar transaction or any other transaction having substantially the same economic effect.

(a)Effective as of the Closing, absent any Actual Fraud, Seller (on its own and on behalf of its Affiliates and each of their respective direct and indirect equityholders, successors and assigns) hereby unconditionally and irrevocably and forever releases and discharges Buyer and the Companies and all of their respective past, present and future directors, officers, mangers, members, equityholders and employees, and all of the foregoing Persons’ successors, assigns and agents (each, a “Buyer Released Party”), of and from, and hereby unconditionally and irrevocably waives, any and all claims, debts, losses, expenses, Proceedings, covenants, liabilities, suits, judgments, damages, actions and causes of action, obligations, accounts, and liabilities of any kind or character whatsoever, known or unknown, contingent or unconditional, matured or unmatured, fixed or variable, suspected or unsuspected, in contract or tort, at Law or in equity, direct or indirect that Seller (or any of its Affiliates and each of their respective direct and indirect equityholders, successors and assigns) ever had, now has or ever may have or claim to have against any Buyer Released Party, that arise out of, relate to, or are in any way connected with Seller’s (or any of Seller’s Affiliates or Seller’s or such Affiliate’s respective direct and indirect equityholders, successors and assigns) past or present (x) direct or indirect ownership of any equity securities issued by the Companies or (y) relationship with the Companies (each, a “Seller Released Claim”); provided, however, that this release shall not affect (a) any Seller Released Claims related to the rights of Seller or its Affiliates under this Agreement or any Transaction Document, including any breach or alleged breach of or liabilities under this Agreement or any other Transaction Documents

or any recourse or similar rights of Seller or its Affiliates set forth in this Agreement or (b) any right to indemnification, exculpation or advancement of expenses, whether under corporate indemnification, director and officer insurance or otherwise, to which any individual may be entitled as a result of such individual’s service as a director, manager, officer, or employee of the Companies. For purposes of clarification and avoidance of doubt, notwithstanding any other provision of the release in this Section 6.13(a), this release does not (i) waive or release any claim for breach or enforcement of this release, or (ii) waive or release any right or claim that may not be waived or released by applicable Law.

(iii)acquiring a direct or indirect interest, by joint venture, merger, stock purchase, asset purchase or other business purchase or combination, in a business (the “Acquired Business”) that is engaged in the Competitive Activities so long as the Competitive Activities do not represent more than fifty percent (50%) of the gross revenues of such Acquired Business;

(iv)engaging in any (A) expansion or extension of the Double E Pipeline, including interconnecting the Double E Pipeline with other systems, or (B) managing, operating, owning, funding, or investing in any Person or business development activity to increase Double E Pipeline’s access to or receipts of natural gas supplies downstream of processing; or

(v)performing services for or engaging in any business with Buyer or any of its Affiliates or Subsidiaries, including performing any duties or obligations as may be required pursuant to the Transition Services Agreement.

Notwithstanding anything to the contrary in this Section 6.14, the Parties acknowledge and agree that in the event of a Change of Control, this Section 6.14 shall terminate and Seller and its Affiliates shall no longer be bound by or subject to the restrictive covenants herein.

(d)Each Restricted Party acknowledges and agrees that the scope of activity restrictions, and duration of the covenants contained in Section 6.14(b) and Section 6.14(c) are the result of arm’s-length bargaining and are fair and reasonable in light of (i) the Restricted Parties’

level of control over and contact with the Companies’ and Buyer’s (and any of its respective subsidiaries’) business, and association with the Companies and Buyer’s (and any of its respective subsidiaries’) goodwill in all jurisdictions in which the Companies and Buyer (and any of its respective subsidiaries) conduct business; and (ii) the consideration that Seller is receiving in connection with the transactions contemplated by this Agreement and the goodwill being conveyed and for which Buyer is paying. Each Restricted Party further acknowledges and agrees that the restrictions set forth in Section 6.14(b) and Section 6.14(c) do not impose any greater restraint than is necessary to protect the legitimate business interests of Buyer, have been specifically negotiated by sophisticated commercial parties, and constitute a material inducement for Buyer enter into this Agreement and consummate the transactions contemplated by this Agreement. The covenants contained in Section 6.14(b) and Section 6.14(c) and each provision (and portion) hereof are severable and distinct covenants and provisions (and portions). The invalidity or unenforceability of any such covenant or provision (or portion) as written shall not invalidate or render unenforceable the remaining covenants or provisions (or portions) hereof, and any such invalidity or unenforceability in any jurisdiction shall not invalidate or render unenforceable such covenant or provision (or portion) in any other jurisdiction. It is the desire and intent of the Buyer and the Restricted Parties that the provisions of Section 6.14(b) and Section 6.14(c) (and all portions thereof) be enforced to the fullest extent permitted under applicable Law. Each Restricted Party acknowledges that Section 6.14(b) and Section 6.14(c) are reasonable and enforceable in all respects; nonetheless, if any of the restrictions of Section 6.14(b) and Section 6.14(c) (or any portions thereof) are found by a court of competent jurisdiction to be unreasonable, overly broad, or otherwise unenforceable, Buyer and the Restricted Parties intend that such restrictions (and the applicable portions thereof) shall not be thereby terminated but shall be modified by such court of competent jurisdiction so as to be valid and enforceable and, as so modified, to be fully enforced. Each Restricted Party further acknowledges that a breach or threatened breach of Section 6.14(b) and Section 6.14(c) would cause irreparable harm to Buyer for which it would have no adequate remedy at Law, that it would be impractical and extremely difficult to determine Buyer’s and its Affiliates’ damages in the event of a breach or threatened breach, and that Buyer and its Affiliates shall be entitled to seek immediate injunctive relief and specific performance as remedies for any such breach in accordance with Section 10.24. Such remedies shall not be the exclusive remedies for a breach or threatened breach of Section 6.14(b) and Section 6.14(c) but shall be in addition to all other remedies available at law an equity, including the recovery of damages.

6.15Notice of Events. During the Interim Period, the Seller shall, on behalf of themselves and the Companies, deliver written notice to Buyer (each such notice, a “Supplement”) if any Company or Seller become aware of any matter first arising or first occurring during the Interim Period as necessary to complete or correct any information in the Schedules with respect to any representation or warranty or any breach of any covenant set forth herein. For all purposes of this Agreement, the Schedules shall be deemed to include only that information contained therein on the date hereof and shall be deemed to exclude all information contained in any supplement or modification thereto. Notwithstanding the foregoing, the Seller shall only have an obligation to deliver a Supplement in the event that such matter has had or would reasonably be expected to have, individually or in the aggregate, a Material Adverse Effect.

6.16Assignment and Assumption of Certain Excluded Liabilities. Prior to the Closing, Seller shall use commercially reasonable efforts to cause the Companies, as applicable, to convey and assign to Seller the Excluded Claims, including a partial assignment of any necessary

associated portions of any agreements related to the Excluded Claims, and Seller shall assume the Excluded Claims; provided, however, that such assignment and assumption shall not be a condition to Closing required under Article VII, nor shall compliance by Seller with this Section 6.16 in any event constitute a breach or non-compliance by Seller for purposes of Section 7.2 or for purposes of termination of this Agreement pursuant to Article IX.

6.17Continuing Employees. Beginning on the date hereof, Seller shall make available to Buyer each of the Subject Employees listed on Schedule 6.17 to discuss potential continuing employment following the Closing with a Company, Buyer or an Affiliate of Buyer. Seller agrees that it will not directly or indirectly discourage any of such Subject Employees from accepting an offer of employment from Buyer. Buyer shall provide Seller, in writing, not later than three (3) calendar days prior to the Closing Date, a list of those Subject Employees who have accepted offers to begin employment with a Company, Buyer or an Affiliate of Buyer as of and immediately after the Closing (each, a “Continuing Employee”). Further, Seller agrees that it will use commercially reasonable efforts to reasonably assist Buyer in communicating with the Continuing Employees regarding the transactions contemplated by this Agreement.

From and after the date hereof, Buyer shall use commercially reasonable efforts to, and in any event within fifteen (15) days following Closing, Buyer shall cause Summit Permian to, obtain replacement surety bonds for those such bonds listed on Schedule 3.18 and provide evidence of the same to Seller. After Seller receives evidence of the replacement surety bonds from Buyer, Seller shall terminate the existing surety bonds set forth on Schedule 3.18. From and after the Closing until such surety bonds have been so replaced and terminated in accordance with this Section 6.21, Buyer shall indemnify the Seller and its Affiliates from and against any losses actually incurred by any of them arising out of or with respect to any of the then-outstanding surety bonds.

6.22Termination of Summit Marketing Transaction Confirmation. Immediately prior to or in connection with the Closing, the Seller shall cause Summit Permian and Summit Marketing to terminate that certain Transaction Confirmation.

6.23Post-Closing Matters. Following the Closing, Seller shall use its commercially reasonable efforts to take the actions described on Exhibit H.

(d)By Seller, if Seller is not then in material breach of any provision of this Agreement, if satisfaction of any of the conditions in Article VIII on or prior to the Outside Date is or becomes impossible (other than through failure of Seller to comply with its obligations under this Agreement), and such breach, if curable, is not cured within 10 days after receipt of written notice thereof from Seller; provided, however, that if, at the end of such 10-day period, Buyer is proceeding in good faith to cure such breach, Buyer shall have an additional 10 days from the end of such 10-day period to effect such cure (or any shorter period of time that remains between the date Seller provides written notice of such violation or breach and the Outside Date); or

(e)By Buyer, if Buyer is not then in material breach of any provision of this Agreement, if satisfaction of any of the conditions in Article VII on or prior to the Outside Date is or becomes impossible (other than through failure of Buyer to comply with its obligations under this Agreement); provided, however, that if, at the end of such 10-day period, Seller is proceeding in good faith to cure such breach, Seller shall have an additional 10 days from the end of such 10- day period to effect such cure (or any shorter period of time that remains between the date Buyer provides written notice of such violation or breach and the Outside Date).

Buyer acknowledges and agrees, on behalf of itself and its Affiliates, that following the Closing, neither Seller nor any of its Affiliates or Representatives shall have any liability for any breach or inaccuracy of any representation or warranty within Section 10.1(b), except in the event of Actual Fraud. For the avoidance of doubt, the absence of coverage under the R&W Policy for any reason, including due to exclusions from coverage thereunder or the failure of the R&W Policy to be in full force and effect for any reason, shall not expand, alter, amend, change or otherwise affect Seller’s or its Affiliates’ or Representatives’ or any of their respective successors’ and assigns’ liability under this Agreement.

10.3Indemnification by Seller. Seller hereby agrees to indemnify and hold harmless the Buyer, its Affiliates and the respective directors, managers, officers, employees, successors and permitted assigns of any of the foregoing (“Buyer Indemnified Parties”) from and against any and all Losses which any of them may suffer, sustain or become subject to, as the result of, arising out of, relating to or in connection with:

(a)any misrepresentation or breach of any of the Seller Fundamental Representations made by the Seller in this Agreement;

(b)the breach by Seller of any covenant in this Agreement or any Transaction Document by Seller;

(c)(i) any Taxes of Seller, (ii) any Taxes of the Companies for all Pre-Closing Periods, and (iii) with respect to any Straddle Period, any Taxes of the Companies attributable to the portion of such Straddle Period that ends on and includes the Closing Date;

10.4Indemnification by Buyer. Buyer hereby agrees to indemnify and hold harmless Seller, its Affiliates and the respective directors, managers, officers, employees, successors and permitted assigns of any of the foregoing (“Seller Indemnified Parties”) from and against any and all Losses which any of them may suffer, sustain or become subject to, as the result of, arising out of, relating to or in connection with:

(a)In the event any Buyer Indemnified Parties seek indemnification from Seller for Losses arising based on matters set forth in Section 10.3(a) or Section 10.3(c), Buyer shall first use commercially reasonable efforts to promptly seek collection and recovery pursuant to the R&W Policy to the fullest extent of the limits under the R&W Policy; provided, however, that nothing shall require the Buyer to commence litigation to recover proceeds under such R&W Policy. In the event Buyer is unable to recover for such Losses in accordance with the foregoing, Buyer may seek recovery for such Losses directly from the Seller.

(b)Subject to Section 10.5(a), in the event Buyer Indemnified Parties seek indemnification from Seller for any Losses arising from Actual Fraud or any other matters set forth in Section 10.3, Buyer may seek recovery for such Losses directly from the Seller.

(c)In the event Seller Indemnified Parties seek indemnification from Buyer for any Losses arising from Section 10.4, Seller may seek recovery for such Losses directly from the Buyer.

(a)Notwithstanding anything to the contrary herein, absent Actual Fraud, in no event shall the aggregate liability of the Seller in connection with this Agreement or the Transaction Documents, including the transactions contemplated herein and therein, exceed the Purchase Price.

(b)The Buyer Indemnified Parties shall take, and shall cause the Companies to take, all commercially reasonable steps to mitigate a Loss upon becoming aware thereof and of the event which gives rise thereto. The Seller Indemnified Parties shall take and cause their respective Affiliates to take all commercially reasonable steps to mitigate a Loss upon becoming aware

thereof and of the event which gives rise thereto. Such parties will each also use commercially reasonable efforts to pursue claims and collect any amounts to which they may be entitled under insurance policies or from third parties (pursuant to indemnification agreements or otherwise). The Parties agree that no Indemnified Party shall have any recourse under this Article X for any Losses that such Indemnified Party would not have suffered had such Indemnified Party exercised commercially reasonable efforts to mitigate such Losses within a reasonable amount of time following the discovery by such Indemnified Party of the fact, event or circumstance giving rise to such Losses (and for an Indemnified Party that is not a natural Person, the bringing to the attention of a responsible officer thereof of such fact, event or circumstance).

(c)Notwithstanding the foregoing or anything herein in the contrary, the Buyer Indemnified Parties shall not be entitled to indemnification pursuant to this Article X for any Loss underlying such indemnification claim to the extent that such Loss (or any part thereof) arises, or is increased, as a result of a change after the Closing in any accounting principle, method or policy (including any such change in GAAP or application thereof), in any Tax reporting practice of the Companies and in no event shall Seller have any liability for indemnification under this Article X for any Losses to the extent such Losses are caused or initiated by any action or omission by any Buyer Indemnified Party or any Company at the request or direction of any Buyer Indemnified Party, including to the extent any Losses resulted from the bad faith, gross negligence or willful misconduct of such Buyer Indemnified Parties.

(d)The amount of any and all Losses indemnifiable under this Agreement shall be determined net of any amounts actually recovered by a Buyer Indemnified Party (or any of its Affiliates) with respect to such Losses from any third party, including any indemnity, contribution or other similar payment, or under or pursuant to any insurance policy pursuant to which or under which such Buyer Indemnitee (or any of its Affiliates) has rights (including the R&W Policy), it being understood that any amounts recovered under or pursuant to any insurance policy shall be calculated net of any reasonable costs associated with pursuing such insurance proceeds and reasonable out-of-pocket costs and any costs or expenses attributable to increases in insurance premiums. If Seller has actually indemnified or held harmless Buyer or another Buyer Indemnified Party upon a claim for indemnification pursuant to this Agreement and, subsequently, there is an actual payment under the R&W Policy (whether to Buyer, another insured under the R&W Policy or a third party) for a claim involving the same or related facts that gave rise to the indemnification claim, then Buyer shall (or shall cause the other insured under the R&W Policy to) use such insurance proceeds (net of any costs of recovery or other reasonable costs and expenses related to the insurance claim) and promptly reimburse Seller for any indemnification amount previously paid by Seller.

(e)For purposes of this Article X, (i) any inaccuracy in or breach of any representation or warranty and (ii) the amount of any Losses arising from such breach of any representation or warranty, shall be determined without regard to any materiality, Material Adverse Effect or other similar qualification contained in or otherwise applicable to such representation or warranty; provided, however, that this Section 10.6 shall not apply to any reference to a Material Contract or a material Permit or Section 3.5(a).

time for any Loss under this Agreement, and to the extent a Party or any of its Affiliates is compensated for a matter through the adjustments provided for in Section 2.6 or otherwise, such Party and its Affiliates will not have a separate right to indemnification or adjustment in another portion of Section 2.6 for such matter. Without limiting the generality of the prior sentence, if a set of facts, conditions or events constitutes a breach of more than one representation, warranty, covenant or agreement that is subject to the indemnification obligations under this Article X as applicable, only one recovery of Losses shall be allowed, and in no event shall there be any indemnification or duplication of payments or recovery under different provisions of this Agreement arising out of the same facts, conditions or events.

(a)In the event that any Proceedings shall be instituted, or that any Claim shall be asserted, by any third party in respect of which payment may be sought under Section 10.3 and Section 10.4 hereof (excluding any Proceeding of a claim in respect of which payment is sought solely from the R&W Policy) (an “Indemnification Claim”), the Indemnified Party shall promptly cause written notice of the assertion of any Indemnification Claim of which it has knowledge which is covered by this Agreement to be forwarded to the Indemnifying Party, including reasonable supporting details (including an estimate of the Losses associated therewith) and copies of all correspondence related thereto. The failure of the Indemnified Party to give reasonably prompt notice of any Indemnification Claim shall not release, waive or otherwise affect the Indemnifying Party’s obligations with respect thereto except to the extent that the Indemnifying Party is materially prejudiced as a result of such failure. With respect to any Indemnification Claim, the Indemnifying Party shall be entitled, at its sole cost and expense, (i) to participate in the defense of such Indemnification Claim to the extent giving rise to the Indemnified Party’s claim for indemnification or (ii) at its option (subject to the limitations set forth below), to assume control of such defense and appoint lead counsel reasonably acceptable to the Indemnified Party; provided that, as a condition precedent to the Indemnifying Party’s right to assume control of such defense, it must first notify the Indemnified Party in writing within thirty days after the Indemnified Party has given notice of the Indemnification Claim that the Indemnifying Party will indemnify the Indemnified Party from and against the entirety of any Losses (without any limitations) the Indemnified Party may suffer resulting from, arising out of, relating to, or caused by the Indemnification Claim in accordance with the terms of this Agreement (including the limitations set forth in Section 10.6). Notwithstanding the foregoing, the Indemnifying Party shall not have the right to assume control of such defense if the Indemnification Claim for which the Indemnifying Party seeks to assume control (I) seeks non-monetary relief, (II) involves criminal or quasi-criminal allegations, (III) involves a claim by a Governmental Authority that would adversely affect the licensure, enrollment or certification of any of the Companies or their Affiliates, or (IV) involves a claim that, in the good faith judgment of the Indemnified Party, the Indemnifying Party failed or is failing to prosecute or defend in good faith.

(b)In the event that the Indemnifying Party fails to elect to assume control of the defense of any Indemnification Claim in the manner set forth in Section 10.7(a), the Indemnified Party may defend against, and consent to the entry of any judgment or enter into any settlement with respect to, the Indemnification Claim in any manner it may deem appropriate (and the Indemnified Party need not consult with, or obtain any consent from, any Indemnifying Party in connection therewith). If the Indemnifying Party has not yet admitted its liability to defend the

Indemnified Party against a third party Claim, the Indemnified Party shall send written notice to the Indemnifying Party of any proposed settlement and the Indemnifying Party shall have the option for ten (10) days following receipt of such notice to (i) admit in writing its liability to indemnify the Indemnified Party from and against the Loss and if liability is so admitted, either

(a)consent to such settlement or (b) reject, in its reasonable judgment, the proposed settlement or

(ii)deny liability. Any failure by the Indemnifying Party to respond to such notice shall be deemed to be an election under subsection (ii) above.

(c)If the Indemnifying Party is controlling the defense of any Indemnification Claim in accordance with Section 10.7(a), (i) the Indemnified Party may nonetheless participate, at his, her or its own expense, in the defense of such Indemnification Claim, and (ii) the Indemnifying Party will not settle or compromise any Indemnification Claim or permit a default or consent to entry of any judgment without the prior written consent of the Indemnified Party (such consent not to be unreasonably withheld, conditioned, or delayed); provided, that the Indemnified Party shall have no obligation of any kind to consent to the entrance of any judgment or into any settlement unless such judgment or settlement (A) is for only money damages, the full amount of which shall be paid by or on behalf of the Indemnifying Party and (B) includes, as a condition thereof, an express, unconditional release of the Indemnified Party from any liability or obligation with respect to such Indemnification Claim.

(d)Irrespective of which party controls the defense of any Indemnification Claim, the other parties to this Agreement will, and will cause any non-party Affiliate to, cooperate with the controlling party in such defense and make available to the controlling party all witnesses, pertinent records, materials and information in such non-controlling party’s possession or under its control relating thereto as is reasonably required by the controlling party. The parties agree that all communications between any party and counsel responsible for or participating in the defense of any Indemnification Claim shall, to the extent possible, be made so as to preserve any applicable attorney-client or work-product privilege.

(e)If an Indemnified Party seeks indemnification under this Article X with respect to any matter that does not involve an Indemnification Claim, the Indemnified Party shall give written notice to the Indemnifying Party promptly after discovering the liability, obligation or facts giving rise to such claim for indemnification, describing the nature of the claim in reasonable detail, the amount thereof (if known and quantifiable), and the basis thereof; provided, that any failure to so notify or any delay in notifying the Indemnifying Party shall not relieve the Indemnifying Party of its or his obligations hereunder except to the extent that the Indemnifying Party is materially prejudiced by such failure or delay, and provided further, that the Buyer Indemnified Parties shall be responsible to submit claims in respect of the R&W Policy. If the Indemnifying Party has delivered an indemnity dispute notice to the Indemnified Party, the Indemnifying Party and the Indemnified Party shall proceed in good faith to negotiate a resolution to such dispute.

10.16Disclosure. Seller may, at its option, include in the Schedules items that are not material or required by this Agreement, and any such inclusion, or any references to dollar amounts, shall not be deemed to be an acknowledgment or representation that such items are material, to establish any standard of materiality or to define further the meaning of such terms for purposes of this Agreement. In no event shall disclosure of any matter, fact, occurrence, information or circumstance in the Schedules be deemed or interpreted to broaden the scope of the representations and warranties, obligations, covenants, conditions, indemnities or agreements contained in this Agreement, or to create any representation, warranty, obligation, covenant, condition, indemnity or agreement that is not contained in this Agreement. In particular, if the Schedules contain supplementary information not specifically required under this Agreement to be included in the Schedules, such additional matters are set forth solely for informational purposes, are not represented or warranted in this Agreement and do not necessarily include other matters of a similar nature. In addition, the disclosure of any matter in the Schedules is not to be deemed an admission against any Party that such matter actually constitutes noncompliance with or a violation of contract or Law or other topic to which such disclosure is applicable. In disclosing any matter, fact, occurrence, information or circumstance in the Schedules, no Party is waiving any attorney-client privilege associated with any such matter, fact, occurrence, information or circumstance, or any protection afforded by the “work product doctrine” with respect to any of the same. Any exception, qualification or other disclosure set forth on the Schedules attached to this Agreement with respect to a particular representation or warranty in this Agreement shall be deemed to be an exception, qualification or other disclosure with respect to all other representations or warranties contained in this Agreement to the extent any description of facts regarding the event, item or matter disclosed is adequate so as to make reasonably apparent on the face of such disclosure that such exception, qualification or disclosure is applicable to such other

This Agreement may be executed in any number of counterparts, each of which shall be deemed an original, but all of which together shall constitute one and the same instrument.

Each of the Parties agrees that a judgment in any such dispute may be enforced in other jurisdictions by suit on the judgment or in any other manner provided by Law.

partner, member, manager, agent or Affiliate of any of the foregoing (each, a “Non-Recourse Party”) shall have any liability for any obligations or liabilities of the Parties to this Agreement or for any claim (whether in tort, contract or otherwise) based on, in respect of, or by reason of, the transactions contemplated hereby or in respect of any representations made or alleged to be made in connection herewith. Without limiting the rights of any Party against the other Party hereto, in no event shall any Party or any of its Affiliates seek to enforce this Agreement against, make any claims for breach of this Agreement against, or seek to recover monetary damages from, any Non- Recourse Party.

10.26Legal Representation. Following the Closing, Locke Lord, LLP may serve as counsel to Seller and its Non-Recourse Parties in connection with any litigation, claim or obligation arising out of or relating to this Agreement, notwithstanding such representation or any continued representation of any other Person, and each of the Parties (on behalf of itself and each of its Non-Recourse Parties) consents thereto and waives any conflict of interest arising therefrom. The decision to represent Seller and its Affiliates shall be solely that of Locke Lord, LLP. Any privilege attaching as a result of Locke Lord, LLP representing Seller or any of its Non-Recourse Parties (including the Companies) in connection with this Agreement shall survive the Closing and shall remain in effect; provided, that such privilege from and after the Closing shall be assigned to and controlled by Seller; provided, further, that in the event that any dispute arises after the Closing between Buyer or any Company, on the one hand, and any party other than the Parties or any of their respective Affiliates, on the other hand, then Buyer and the Companies may assert such privilege to prevent the disclosure of any Privileged Communications by Locke Lord, LLP to such third party. In furtherance of the foregoing, each of the Parties agrees to take the steps necessary to ensure that any privilege attaching as a result of Locke Lord, LLP representing the Companies in connection with this Agreement shall survive the Closing, remain in effect and be assigned to and controlled by Seller. As to any privileged attorney client communications between Locke Lord, LLP and the Companies prior to the Closing Date (collectively, the “Privileged Communications”), Buyer, together with any of its Affiliates, successors or assigns, agree that no such party may use or rely on any of the Privileged Communications in any action or claim against or involving any of the Parties or any of their respective Non-Recourse Parties after the Closing.
