Such actions shall include, but not be limited to, using reasonable best efforts to: (i) maintain in effect the Commitment Letters,providedthat Acquirors may replace or amend the Debt Commitment Papers (including adding new lenders, lead arrangers, bookrunners, syndication agents or similar entities

- 30 -

to the Debt Commitment Papers pursuant to the terms thereto) in accordance with thisSection 6.4(c) andSection 6.4(d); (ii) ensure the participation by senior management of Acquirors in, and assistance by senior management of Acquirors with, the preparation of rating agency presentations and meetings and meetings with prospective lenders; (iii) cause the Equity Financing to be consummated upon satisfaction of the conditions set forth in the Equity Commitment Letter; (iv) satisfy on a timely basis all Financing Conditions (unless such conditions are waived) that are within Acquirors’ or their respective Affiliates’ control; (v) negotiate, execute and deliver Debt Financing Documents on terms no less favorable to Acquirors than the terms contained in the Debt Commitment Papers (including any “market flex” provisions of the Fee Letter) and (vi) diligently and in good faith enforce its rights under the Commitment Letters.

Acquirors shall not, without the prior written consent of Sellers (not to be unreasonably withheld, conditioned or delayed), permit any amendment, supplement or modification to, or any waiver of any provision or remedy under, or replace, or enter into any other agreements, side letters or arrangements relating to, (x) the Equity Commitment Letter or (y) the Debt Commitment Papers, if such amendment, supplement, modification, waiver, replacement or other agreements, side letters or arrangements (provided that the existence or exercise of “market flex” provisions contained in the Fee Letter shall not be deemed to constitute a modification or amendment of the Debt Commitment Papers) to the Debt Commitment Papers would (A) reasonably be expected to make the timely funding of the Financing or satisfaction of the conditions to obtaining the Financing materially less likely to occur, (B) reduce the aggregate amount of the Financing from that contemplated in the Commitment Letters to an amount less than the Required Amount, (C) materially and adversely affect the ability of Acquirors to enforce their rights against any of the other parties to the Commitment Letters as so amended, supplemented, modified, waived or replaced, relative to the ability of Acquirors to enforce their rights against any of such other parties to the Commitment Letters as in effect on the date hereof or (D) add new or additional conditions, or otherwise expand upon the conditions precedent to the Financing as set forth in the Commitment Letters, or modify the terms of the Financing, in a manner that would reasonably be expected to materially prevent, impede or delay the timely funding of the Required Amount on the Closing Date or the consummation of the transactions contemplated by this Agreement (the “Prohibited Conditions”). Upon any such amendment, supplement, modification, waiver or replacement of the Debt Commitment Papers in accordance with thisSection 6.4(c) orSection 6.4(d) below, Acquirors shall promptly deliver to Sellers a true and complete copy thereof, and the terms “Debt Commitment Letter,” “Debt Commitment Papers” and “Debt Financing” shall refer to the Debt Commitment Papers as so amended, supplemented, modified, waived or replaced and the Debt Financing contemplated thereby. Acquirors shall keep Sellers informed on a reasonably current basis and in reasonable detail of the status of its efforts to arrange and obtain any Financing upon written request by Sellers therefor.

- 31 -

(d) Acquirors shall give Sellers prompt written notice of (i) any material breach, default, termination or written repudiation by any party to the Commitment Letters of which any Acquiror or any of their respective Affiliates becomes aware; (ii) the receipt by Acquirors of any written notice or other written communication from any Financing Source or Equity Investor with respect to any actual or potential breach, default, termination or written repudiation by such party to the Commitment Letters, or of any provisions thereto; and (iii) the occurrence of any event or development that Acquirors expect to have an adverse impact on the ability of Acquirors to obtain the timely funding of the Required Amount on the Closing Date or to consummate the transactions contemplated by this Agreement. As soon as reasonably practicable, but in any event within three Business Days of the date Sellers deliver to Acquirors a written request, Acquirors shall provide any information reasonably requested by Sellers relating to any circumstance referred to in the immediately preceding sentence. Without limiting Acquirors’ obligations hereunder, if any portion of the Debt Financing becomes unavailable or Acquirors become aware of any event or circumstance that makes any portion of the Debt Financing unavailable, in each case, on the terms and conditions contemplated in the Debt Commitment Papers, each Acquiror shall (A) notify Sellers of the occurrence thereof and the reasons therefor on a reasonably prompt basis; (B) use its reasonable best efforts to obtain, as promptly as practicable after the occurrence of such event, alternative financing from the same or alternative financing sources (1) in an amount at least equal to the amount of the Debt Financing or such unavailable portion thereof (in each case, after giving effect to any increase, if any, in the amount of the equity financing to be provided pursuant to the Equity Commitment Letter) and (2) which alternate financing shall not be subject to any conditions precedent that would constitute Prohibited Conditions and shall otherwise be on terms (including structure, covenants and pricing) not materially less favorable to Acquirors than the terms and conditions set forth in the Commitment Letters (including any “market flex” provisions contained in the Fee Letter); (C) keep Sellers reasonably informed on a current basis of the status of their efforts to consummate such alternative financing; and (D) provide Sellers with true and complete fully executed copies of the documentation with respect to any new financing. Neither Acquirors nor any of their respective Affiliates shall amend, modify, supplement, restate, assign, substitute or replace any of the Commitment Letters except as provided herein. Notwithstanding the foregoing, in no event shall Acquirors be under any obligation to disclose any information that may not be disclosed in accordance with the requirements of applicable Law.

(e) Acquirors shall, upon request by any Seller, its current and future Affiliates, and each of their respective current and future direct and indirect equityholders, members, partners and Representatives (collectively, the “Seller Indemnified Parties”), or any TGE Entity, reimburse such Seller Indemnified Parties or TGE Entities, as applicable, for all reasonable and documentedout-of-pocket costs and expenses incurred by such Seller Indemnified Parties or TGE Entities, as applicable, including reasonable attorney’s fees and accountants’ fees, in connection with cooperation required under or with respect to requests made under thisSection 6.4 (including thisSection 6.4(e)) andSection 6.15 (including, for the avoidance of doubt, any fees paid to the holders of the Existing Change of Control Notes in connection with the attainment of the Existing Change of Control Notes Consents);provided that no such reimbursement shall be required to be made until the earlier of (x) the Closing Date or (y) 10 Business Days following the termination of this Agreement in accordance withArticle IX. Acquirors shall indemnify and hold harmless the Seller Indemnified Parties and the TGE Entities from and against any and all Losses suffered or incurred by them in connection with the arrangement and completion of any Financing, capital markets transactions or related transactions in connection with financing the transactions contemplated this Agreement and the other Transaction Documents,and the performance of their respective obligations under thisSection 6.4 (including any action taken in accordance with thisSection 6.4(e)) and any information utilized in connection therewith;provided,however, that the

- 32 -

foregoing obligations to any Seller Indemnified Party shall not apply to any information provided by Sellers or Sellers’ Affiliates or other their respective Representatives or to any Losses incurred (i) as a result of the willful misconduct or gross negligence of any such Seller Indemnified Party or (ii) arising out of any material misstatement or omission of information provided hereunder by any such Seller Indemnified Party. ThisSection 6.4(e) shall survive the consummation of the transactions contemplated by this Agreement and the Closing and any termination of this Agreement, and is intended to benefit, and may be enforced by, each of the third party beneficiaries hereto.

(f) It is the intent of Acquirors to seek to raise equity from third-party investors other than those investors contemplated to fund amounts under the Equity Commitment Letter and in addition to and in excess of the equity contemplated by the Equity Commitment Letter on terms and conditions reasonably acceptable to Acquirors (such additional equity, the “Additional Equity Financing”) in amounts sufficient to eliminate the need for any portion of the Purchase Price to be payable by the issuance by the issuers thereunder of the Seller Notes. In furtherance of the foregoing, Acquirors shall use their commercially reasonable efforts to arrange, consummate and obtain Additional Equity Financing on or before the Closing Date in an aggregate amount at least equal to the aggregate principal amount of Seller Notes set forth onSchedule 2.1;provided, that Acquirors shall not be required in connection with such efforts to provide any consideration or grant any rights to any Person beyond the ability to participate through BIP GP controlled vehicles in such transaction through customaryco-investment vehicles at the same cost as is applicable to Affiliates of BIP GP. To the extent required by the equity sweep provisions of the Seller Note, the net proceeds of any Additional Equity Financing will be used on the Closing Date to reduce on a pro rata basis the portion of the Purchase Price otherwise payable to each of DGD Trust, EMG and Kelso under the Seller Notes and to increase on a pro rata basis the portion of the Purchase Price otherwise payable to each of DGD Trust, EMG and Kelso in cash. Notwithstanding the remainder of thisSection 6.4(f), so long as Acquirors have complied with their obligations in thisSection 6.4(f), in no event will any failure to actually obtain any amount of Additional Equity Financing result in a breach of this Agreement.

Section 6.5Further Assurances; Cooperation. Subject to the terms and conditions of this Agreement, each Party will use its commercially reasonable efforts to take, or cause to be taken, all action, and to do, or cause to be done, all things necessary, proper or advisable under applicable Laws to consummate and make effective the sale of the Subject Interests pursuant to this Agreement, including commercially reasonable efforts to ensure satisfaction of the conditions precedent to each Party’s obligations hereunder. Neither Sellers on the one hand, nor Acquirors on the other hand, will, without the prior written consent of the other, take or fail to take any action that would reasonably be expected to prevent or materially impede, interfere with or delay the transactions contemplated by this Agreement. From time to time after the Closing Date, without further consideration, each Party will, at its own expense, execute and deliver such documents to another Party as such other Party may reasonably request in order to more effectively consummate the sale and purchase of the Subject Interests hereunder.

Section 6.6Public Statements. The Parties shall consult with each other prior to issuing any public announcement, statement or other disclosure with respect to the Transaction Documents or the transactions contemplated thereby and none of Acquirors and their Affiliates, on the one hand, nor Sellers and their Affiliates, on the other hand, shall issue any such public announcement,

- 33 -

statement or other disclosure without having first notified Acquirors, on the one hand, or Sellers, on the other hand, and provided such Parties with, if legally permitted and practically possible, a reasonable time period to review and comment thereon and give due consideration to any reasonable comments thereto;provided that “a reasonable time period” shall in all cases require a Party to inform the other Party with sufficient time to allow such other Party to timely announce publicly or file any reports with the SEC as required under the Exchange Act or the Securities Act or any applicable requirements of a national securities exchange. Notwithstanding the foregoing, any Party may make, without consulting or notifying any other Party, public announcements, statements or other disclosures with respect to the Transaction Documents or the transactions contemplated thereby that are not materially inconsistent with, and do not contain any material information not disclosed in, previous public announcements, statements or other disclosures made by a Party in compliance with thisSection 6.6.

Section 6.7Confidential Information.

(a) For two years after the Closing, Sellers and their respective Affiliates shall not, directly or indirectly, disclose to any Person any information not in the public domain or generally known in the industry, in any form, whether acquired prior to or after the Closing Date, relating to the business, management or operations of the TGE Entities prior to the Closing Date.

(b) Notwithstanding the foregoing, Sellers and their respective Affiliates and any of their respective Representatives may disclose or use any information relating to the business, management or operations of the TGE Entities:

(i) if required by Law, including any applicable stock exchange rule or requirement of the SEC, except that the disclosing Party shall (x) if legally permissible, prior to making any such disclosure, seek a protective order or other relief from the requirement to disclose such information and (y) if it is legally impermissible to seek such relief or if no such relief is granted, disclose only such information as is legally required to be disclosed;

(ii) if such disclosure is to another Person and, at the time such information is provided, such other Person is already in the possession of such information and is bound by confidentiality obligations with respect to such information that are at least as stringent (including, for the avoidance of doubt, with respect to the time period of such confidentiality obligations) as those contained in this Agreement and any other Transaction Documents;

(iii) if such disclosure is to a Representative of any Seller or any Affiliate of any Seller that agrees to keep such disclosure confidential; or

(iv) if the use, private disclosure in the ordinary course of business, or public disclosure of such information is solely undertaken by the TGE Entities and, in each case, such information solely relates to the business and operations of the TGE Entities and not of Sellers, their Affiliates or their respective businesses or operations.

(c) Nothing in this Agreement will prevent any individual from: (i) lawfully initiating communications directly with, cooperating with, providing information to, causing information to be provided to, or otherwise assisting in an investigation by the SEC or any other Governmental Authority regarding a possible violation of any Law; (ii) responding to any inquiry

- 34 -

or legal process directed to an individual from any Governmental Authority; (iii) testifying, participating or otherwise assisting in a Proceeding by any Governmental Authority relating to a possible violation of Law, including providing documents or other confidential information to Governmental Authorities; or (iv) receiving an award for information provided to the SEC or another Governmental Authority. No individual will be required to obtain prior authorization from Acquirors, Sellers or any of their respective Affiliates before engaging in any of the conduct described in the first sentence of thisSection 6.7(c), or to notify Acquirors, Sellers or their respective Affiliates of having engaged in any such conduct.

(d) For the avoidance of doubt, nothing in thisSection 6.7 is intended to, nor does it, modify any confidentiality provisions (including, for the avoidance of doubt, any qualifications and exceptions thereto) contained in any agreement between any of the TGE Entities, on the one hand, and any Seller or any Affiliate of any Seller, on the other hand.

Section 6.8Resignations. Sellers shall and shall cause the TGE Entities to (a) use commercially reasonable efforts to deliver at the Closing duly executed letters of resignation or (b) cause the removal, in each case, effective as of the Closing, of the individuals listed onSchedule 6.8 (collectively, the “Resigning Directors and Officers”).

Section 6.9Certain Insurance and Indemnification Matters.

(a) Acquirors agree that all rights to indemnification, exculpation and advancement of expenses, elimination of liability and exculpation from liabilities existing in favor of (x) any Person (together with such Person’s heirs, executors and administrators) who is or was, or at any time prior to the Closing Date becomes, an officer, director or manager of any TGE Entity or (y) any Person (together with such Person’s heirs, executors and administrators) who is or was serving, or at any time prior to the Closing Date serves, at the request of any TGE Entity as an officer, director, member, general partner, fiduciary or trustee of another Person (other than Persons solely providing, on afee-for-services basis, trustee, fiduciary or custodial services) (each, a “Covered Person”), as provided in the respective Organizational Documents of such TGE Entities in effect as of the date of this Agreement, or pursuant to any other agreements in effect on the date hereof and disclosed inSchedule 6.9(a), shall survive the Closing and shall continue in full force and effect for a period of not less than six years following the Closing Date, and Acquirors shall cause each TGE Entity to honor and maintain in effect all such rights to indemnification, exculpation and advancement of expenses, elimination of liability and exculpation from liabilities during such period. For a period of not less than six years, Acquirors shall not, and shall not cause or permit any TGE Entity to, amend, restate, waive or terminate any Organizational Document of the TGE Entities in any manner that would adversely affect the indemnification or exculpation rights of any such Covered Person.

(b) Acquirors covenant and agree that, during the period that commences on the Closing Date and ends on the sixth anniversary of the Closing Date, with respect to each Covered Person, including, for the avoidance of doubt, any such director, manager or officer that resigned or was removed effective as of the Closing pursuant to this Agreement, Acquirors shall cause such applicable TGE Entity (i) to continue in effect the current fiduciary liability insurance policy or policies that such TGE Entity has as of the date of this Agreement, or (ii) upon the termination or cancellation of any such policy or policies, (x) to provide fiduciary liability or

- 35 -

similar insurance in substitution for, or in replacement of, such cancelled or terminated policy or policies or (y) to provide a “tail” or runoff policy (covering all claims, whether choate or inchoate, made during such six year period), in each case, providing coverage thereunder for acts, events, occurrences or omissions occurring or arising at or prior to the Closing that is no less advantageous to each such Covered Person (including policy limits, exclusions and scope) as such Covered Person as in existence as of the date of this Agreement covering such acts, events, occurrences or omissions under the fiduciary liability insurance or similar policy maintained by the TGE Entities as of the date of this Agreement;provided that Acquirors and the TGE Entities shall not be required to pay premiums for such insurance policy in excess of 300% of the current premium for such coverage, but shall purchase as much of such coverage as possible for such applicable amount.

(c) In the event that any Acquiror or any TGE Entity (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) in one or more series of transactions, directly or indirectly, transfers all or substantially all of its properties and assets to any Person (whether by consolidation, merger or otherwise), then, and in each such case, proper provision shall be made so that such continuing or surviving corporation or entity or transferee of such assets, as the case may be, assumes the obligations set forth in thisSection 6.9.

(d) The provisions of thisSection 6.9 shall survive the consummation of the transactions contemplated hereby for a period of six years;provided,however, that that in the event that any claim or claims for indemnification or advancement of expenses set forth in thisSection 6.9 are asserted or made within suchsix-year period, all rights to indemnification and advancement of expenses in respect of any such claim or claims shall continue until the disposition of such claims. The provisions of thisSection 6.9 (i) are expressly intended to benefit each Covered Person, (ii) shall be enforceable by any Covered Person and its heirs and representatives against the TGE Entities, and (iii) shall be in addition to any other rights such Covered Person or its heirs and representatives have under the Organizational Documents of any TGE Entity or applicable Law.

(e) ThisSection 6.9 shall not be amended, repealed, terminated or otherwise modified at any time in a manner that would adversely affect the rights of a Covered Person as provided herein except with the prior written consent of such Covered Person.

Section 6.10Post-Closing Access; Records. From and after the Closing, Acquirors and their Affiliates shall make or cause to be available to Sellers all books, records, Tax Returns and documents of the TGE Entities (and the assistance of employees responsible for such books, records and documents) upon reasonable notice during regular business hours as may be reasonably necessary for (a) investigating, settling, preparing for the defense or prosecution of, defending or prosecuting any Proceeding, (b) preparing reports to, or filings with, equityholders or Governmental Authorities or (c) such other purposes for which access to such documents is determined by such requesting Seller to be reasonably necessary, including preparing and delivering any accounting or other statement provided for under this Agreement or otherwise, preparing Tax Returns, pursuing Tax refunds or responding to or disputing any Tax audit or other Proceeding, or the determination of any matter relating to the rights and obligations of Sellers or any of their Affiliates under any Transaction Documents;provided,however, that access to such books, records, documents and employees shall not interfere with the normal operations of

- 36 -

Acquirors, their Affiliates or the TGE Entities and the reasonableout-of-pocket expenses of Acquirors, their Affiliates or the TGE Entities incurred in connection therewith shall be paid by Sellers. Acquirors shall cause each TGE Entity to maintain and preserve all such Tax Returns, books, records and other documents for the greater of (i) seven years after the Closing Date and (ii) any applicable statute of limitations, as the same may be extended and, in each case, shall offer to transfer such Tax Returns, books, records and other documents to the Major Sellers at the end of the period in which it maintains and preserves such records.

Section 6.11Exclusivity. Prior to the earlier of the Closing or the termination of this Agreement, Sellers shall not, and shall not permit their Representatives to, directly or indirectly, (i) discuss, encourage, negotiate, undertake, initiate, authorize, recommend, propose or enter into with any Third Party any transaction involving a merger, consolidation, business combination or purchase or disposition of the Subject Interests other than the transactions contemplated by the Transaction Documents (an “Acquisition Transaction”), (ii) facilitate, encourage, solicit or initiate discussions, negotiations or submissions of proposals or offers with any Third Party in respect of an Acquisition Transaction, (iii) furnish or cause to be furnished, to any Third Party, any nonpublic information concerning the Subject Interests in connection with an Acquisition Transaction or (iv) otherwise cooperate in any way with, or assist or participate in, facilitate or encourage, any effort or attempt by any Third Party to do or seek any of the foregoing.

Section 6.12Tax Matters.

(a)Transfer Taxes. Any transfer, documentary, sales, use, stamp, registration and other such Taxes incurred in connection with this Agreement (“Transfer Taxes”) shall be borne by Acquirors, and any Party required by applicable Law to file Tax Returns with respect to such Transfer Taxes shall file all necessary Tax Returns and other documentation with respect to such Transfer Taxes, and the other Parties agree to cooperate in the preparing of any such Tax Return and other documentation. If required by applicable Law, the Parties agree to join in the execution of any such Tax Return and other documentation.

(b)Purchase Price Allocation. Acquirors and Sellers agree to allocate, for U.S. federal income tax purposes, the Purchase Price and any other consideration as determined for U.S. federal income tax purposes (together with the Purchase Price, the “Tax Consideration”) among the GP Interests, theUp-C Interests and the Class A Interests as set forth onSchedule 6.12(b). Acquirors and Sellers agree to use commercially reasonable efforts to allocate the Tax Consideration among the assets of each applicable TGE Entity in a manner consistent with applicable U.S. federal income tax rules, including Section 1060 of the Code and, as applicable, Sections 743(b), 751 and 755 of the Code. Acquirors and Sellers agree to treat and report the transactions contemplated by this Agreement in all respects consistent with such agreed allocation, if any, for purposes of any U.S. federal and applicable state income Taxes (including any statements required under Treasury RegulationsSection 1.751-1(a)(3) and any allocation required under Section 755 of the Code) and not take any action inconsistent with such agreed allocation, if any, except as required by applicable Law or a “determination” within the meaning of Section 1313(a)(1) of the Code;provided,however, that no Acquiror or Seller shall be unreasonably

- 37 -

impeded in its ability and discretion to negotiate, compromise or settle any Tax audit, claim or similar Proceedings in connections with such allocations. If Acquirors and Sellers cannot agree on an allocation or methodology, they will report for Tax purposes based on their own allocation and methodology. Each of the Parties shall promptly notify the other Parties in writing upon receipt of notice or any pending or threatened Tax audit or assessment challenging any allocation of the Tax Consideration.

(c)Cooperation. Prior to the destruction or discarding of any books and records with respect to Tax matters pertinent to any of the TGE Entities, relating to any taxable period beginning on or before the Closing Date, Acquirors or such TGE Entity shall give the Major Sellers reasonable written notice and, if any Major Seller so requests, shall allow, or cause any applicable Person to allow such Major Seller to take, possession of such books and records. Acquirors and Major Sellers further agree, upon request, to use their commercially reasonable efforts (i) to obtain any certificate or other document from any Governmental Authority or any other Person as may be necessary to mitigate, reduce or eliminate any Tax that could be imposed on any of the TGE Entities as a result of the transactions contemplated hereby or for any taxable period of such TGE Entities beginning on or before the Closing Date and (ii) to provide each other with such cooperation and information as either of them reasonably may request of the other in filing any Tax Return or in connection with any audit or other Proceeding in respect of Taxes of any TGE Entity.

(d)Interim Closing. Acquirors and Sellers shall use commercially reasonable efforts to cause any applicable TGE Entity to allocate all items of its income, gain, loss, deduction and credit allocable to the applicable Subject Interests between Acquirors and Sellers based on the “interim closing method” under Section 706 of the Code and the Treasury Regulations thereunder.

Section 6.13Employee Matters.

(a) With respect to those individuals who are employees of a TGE Entity immediately prior to the Closing Date, who do not have an employment agreement with any TGE Entity immediately prior to the Closing Date and who remain employed by an Acquiror or any of its Affiliates immediately following the Closing (the “Continuing Employees”), Acquirors or an Affiliate of Acquirors shall, for a period of 12 months following the Closing, except with the prior written consent of the Chief Executive Officer of TGE GP, (i) continue to employ each Continuing Employee in a position and with a title substantially similar to the position and title that such Continuing Employee held immediately prior to the Closing; (ii) continue to provide the Continuing Employees with annualized base salaries (or hourly wages, as applicable) and annual incentive compensation opportunities that are at least substantially similar to those provided to the Continuing Employees immediately prior to the Closing; and (iii) continue to provide the Continuing Employees with employee benefits that are not, in the aggregate, less favorable than the employee benefits that were available to Continuing Employees immediately prior to the Closing under the TGE Benefit Plans (excluding defined benefit pensions and supplemental retirement benefits, retiree medical or other retiree welfare benefits);provided,however, that any obligation in clauses (ii) and (iii) above to provide Continuing Employees with equity compensation shall not apply if equity securities of TGE (or equity securities of any successor entity) are not listed on a national securities exchange; andprovided,further, that, for the avoidance of doubt, notwithstanding the foregoing proviso, Acquirors shall cause to be awarded all equity compensation contemplated bySchedule 6.3(h) when and as provided onSchedule 6.3(h) to the extent not awarded prior to the Closing Date, and such equity compensation shall be subject to the terms of the applicable award agreement and equity incentive plan.

- 38 -

(b) Effective from and after the Closing Date, to the extent that a Continuing Employee becomes eligible to participate in an employee benefit plan maintained by an Acquiror or an Affiliate of an Acquiror (an “AcquirorBenefit Plan”), Acquirors or the applicable Affiliate of Acquirors shall use commercially reasonable efforts to (i) recognize for purposes of eligibility, vesting and benefit levels under vacation and severance benefits programs under such Acquiror Benefit Plan, service with a TGE Entity, any of their Affiliates or any predecessor of any such entity prior to the date on which such Continuing Employee becomes eligible to participate in the applicable Acquiror Benefit Plan to the extent such service was recognized under the corresponding TGE Benefit Plan, except where it would result in a duplication of benefits; and (ii) waive anypre-existing condition exclusion,actively-at-work requirement or waiting period under an Acquiror Benefit Plan that is a welfare benefit plan, except to the extent suchpre-existing condition exclusion, requirement or waiting period would have applied to such individual under the corresponding TGE Benefit Plan immediately prior to the date on which such Continuing Employee becomes eligible to participate in the applicable Acquiror Benefit Plan; and (iii) provide full credit for allco-payments, deductibles and similar payments such Continuing Employee made or incurred under a TGE Benefit Plan as of immediately prior to the date on which such Continuing Employee becomes eligible to participate in the applicable Acquiror Benefit Plan.

(c) At or immediately following the Closing, Acquirors intend to cause TGE GP and Tallgrass Management, LLC to enter into an employment agreement with each Person listed onSchedule 6.13(c), such employment agreement to reflect the terms set forth onSchedule 6.13(c) with respect to such Person.

(d) Nothing in thisSection 6.13 amends, or will be deemed to establish, amend or prevent the amendment or termination of, any TGE Benefit Plan or any other employee benefits or compensation plan, program or arrangement. No provision of this Agreement shall be construed as a guarantee of continued employment for any employee for any period of time or to prohibit Acquirors or any of their Affiliates from terminating the employment of any Continuing Employee at any time after the Closing. Except as set forth inSection 11.10, nothing in thisSection 6.13 shall create any third-party beneficiary rights in any Continuing Employee.

Section 6.14Non-Interference;Non-Solicitation.

(a) As a material inducement for Acquirors to enter into this Agreement, and in order to protect the confidential and proprietary information and the goodwill that is conveyed by Sellers hereunder, Sellers agree to enter into thisSection 6.14. Each Seller hereby agrees that, during the Restricted Period, such Seller shall not, and such Seller shall cause such Seller’s Affiliates not to, directly or indirectly:

(i) knowingly and intentionally interfere with the business relationship between any Acquiror or TGE Entity following the Closing and any current or prospective customer of a TGE Entity, or any Person that was a customer of a TGE Entity within the twelve month period prior to Closing, including, with knowledge and intent to interfere with such business

relationship, by soliciting, approaching, canvassing, encouraging or enticing any such Person to cease doing business with or reduce the amount of business conducted with any TGE Entity or causing such Person to be solicited, approached, canvassed, encouraged or enticed to cease doing business with or reduce the amount of business conducted with any TGE Entity; or

(ii) engage or employ, or solicit or contact with a view to the engagement or employment of, any Continuing Employee (other than employees paid on an hourly basis and whose job is solely clerical or does not involve any supervisory responsibility) and who performs services with respect to the Business;provided,however, that Sellers and any of their Affiliates may engage in general solicitations for employees in the ordinary course of business and consistent with past practice, including any search firm engagement which, in any such case, is not directed or focused on employees of the TGE Entities or any other employee or contractor of any Acquiror or any TGE Entity.

(b) Each Seller acknowledges and agrees that the scope of activity restrictions and duration of the covenants contained in thisSection 6.14 are the result ofarm’s-length bargaining and are fair and reasonable in light of (i) such Seller’s level of control over and contact with the TGE Entities’ business, and association with the TGE Entities’ goodwill in all jurisdictions in which they conduct business; (ii) such Seller’s knowledge of the TGE Entities’ confidential and proprietary information, which information is conveyed hereunder and would inevitably be disclosed if such Seller were to violate any of the provisions of thisSection 6.14; and (iii) the consideration that such Seller is receiving in connection with the transactions contemplated by this Agreement and the other Transaction Documents, and the goodwill and confidential and proprietary information that such Seller is conveying and for which Acquirors are paying. Each Seller further acknowledges and agrees that the restrictions set forth in thisSection 6.14 do not impose any greater restraint than necessary to protect the legitimate business interests of Acquirors, have been specifically negotiated by sophisticated commercial parties and constitute a material inducement for Acquirors to enter into this Agreement and consummate the transactions contemplated by this Agreement and the other Transaction Documents. The covenants contained in thisSection 6.14 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.

(c) It is the desire and intent of the Parties that the provisions of thisSection 6.14 (and portions thereof) be enforced to the fullest extent permitted under applicable Law. Sellers acknowledge that thisSection 6.14 is reasonable and enforceable in all respects; nonetheless, if any of the restrictions of thisSection 6.14 (or portions thereof) are found by a court of competent jurisdiction to be unreasonable, overly broad, or otherwise unenforceable, the Parties intend that such restrictions (and portions thereof) shall not be thereby terminated but shall be modified by such court so as to be valid and enforceable and, as so modified, to be fully enforced.

- 40 -

(d) Each Party further acknowledges that a breach or threatened breach of thisSection 6.14 would cause irreparable harm to Acquirors for which they would have no adequate remedy at law, and that Acquirors and their Affiliates shall be entitled to immediate injunctive relief and specific performance as remedies for any such breach. Such remedies shall not be the exclusive remedies for a breach or threatened breach of thisSection 6.14 but shall be in addition to all other remedies available at law and in equity, including the recovery of damages.

Section 6.15Actions with Respect tothe Existing Change of Control Notes Consents.

(a) As soon as practicable after Sellers’ receipt of any written request by Acquirors to do so, at Acquirors’ sole cost and expense and without any cost or expense to Sellers or the TGE Entities, Sellers shall, consistent with the requirements of the Existing Change of Control Notes, as applicable, cause the issuers of the Existing Change of Control Notes to commence one or more consent solicitations to obtain the Existing Change of Control Notes Consents, the consummation of which shall be contingent upon the occurrence of the Closing.

(b) The Sellers shall use reasonable best efforts to obtain reasonable assurances from each of Fitch Ratings, Inc., Moody’s Investor Service, Inc., and S&P Global Ratings, a division of S&P Global, Inc.

The consummation of any such Change of Control Offer, Alternate Offer or other offer to purchase, and purchase of validly tendered notes pursuant thereto, shall be contingent upon the occurrence of the Closing and a Change of Control Triggering Event (as defined in the applicable indenture).

(c) Notwithstanding anything herein to the contrary, the attainment of the Existing Change of Control Notes Consents or the completion of other Specified Funded Indebtedness Accommodations shall not be a condition to the Closing.

(d) Acquirors shall prepare, or cause to be prepared, all necessary and appropriate documentation in connection with the Existing Change of Control Notes Consents and other Specified Funded Indebtedness Accommodations.

Following the Closing, GP Acquiror shall, except as prohibited by Law, use its reasonable best efforts to (a) cause the board of directors of TGE GP to declare and cause TGE to pay a regular quarterly cash distribution on the Class A Shares relating to the fiscal quarter of TGE during which the Closing Date occurs in accordance with the TGE Partnership Agreement and in the ordinary course of business consistent with past practice in an amount per Class A Share not less than the amount specific onSchedule 6.17(a) and (b) cause the board of directors of TGE GP to authorize and cause TGE, in its capacity as the managing member of TE, to declare and cause TE to pay a regular quarterly cash distribution on the TE Units relating to the fiscal quarter of TGE during which the Closing Date occurs in accordance with the TE LLC Agreement and in the ordinary course of business consistent with past practice in an amount not less than the amount specified onSchedule 6.17(b).

Section 6.18Additional Sellers. Immediately following the execution of this Agreement, the Major Sellers shall use commercially reasonable efforts to cause each of the Persons set forth onSchedule 2.1 as a “Joinder Party” (each, a “Joinder Party”) to sign a joinder to this Agreement, in substantially the form attached hereto asExhibit C (a “Joinder”), with respect to the TE Units and Class B Shares specified onSchedule 2.1 opposite such Joinder Party’s name, and the Parties hereby agree to accept each Joinder upon execution thereof. To the extent any such Person executes a Joinder, (a) such Person shall constitute and be deemed to be a “Sponsor” and a “Seller” for all purposes under this Agreement, and the TE Units and Class B Shares to which such Joinder relates shall constitute and be deemed to be “Subject Interests” for all purposes under this Agreement, and (b) the Purchase Price shall be adjusted upward to reflect the portion of the Purchase Price with respect to the TE Units an Class B Shares to which such Joinder relates.

Section 6.19Participatory Rights. After the Closing, Acquirors shall use their respective reasonable best efforts, in good faith, to, and to cause their respective controlled Affiliates to, establish and offer each of the Persons listed onSchedule 6.13(c), to the extent they continue as employees of the TGE Entities, and any other employees Acquirors may determine, an opportunity to participate in an incentive or equity-based program or vehicle relating to Acquirors’ investment in the TGE Entities for so long as the Acquirors or their Affiliates maintain control over the TGE Entities.

Notwithstanding anything in thisSection 8.1 to the contrary, a claim relating to any breach or inaccuracy in respect of which indemnity may be sought under this Agreement shall survive the time at which it would otherwise terminate pursuant to thisSection 8.1 until such claim is finally resolved or judicially determined, if notice of such claim giving rise to such right of indemnity shall have been given pursuant toSection 8.3 to the party against whom such indemnity may be sought prior to such time.

Section 8.2Indemnification.

(a) From and after the Closing, Acquirors, their current and future Affiliates and each of the current and future direct and indirect equityholders, members, partners, directors, managers, officers, employees and agents of Acquirors or their current and future Affiliates (collectively, the “Acquiror Indemnified Parties”) shall be indemnified and held harmless by Sellers, severally and not jointly, for any Losses incurred or sustained by such Acquiror Indemnified Party based upon, attributable to, resulting from or by reason of (including any and all Proceedings, demands or assessments arising out of) (i) the incorrectness, falsity or breach of,

- 46 -

as of the date hereof or as of the Closing Date with the same force and effect as though made on and as of such date (except those representations and warranties that expressly relate only to an earlier date, in which case as of such earlier date), any of the Seller Fundamental Representations or (ii) any breach of any covenant or other agreement on the part of Sellers to be performed in whole or in part after the Closing.

(b) From and after the Closing, Sellers, their respective current and future Affiliates and each of the current and future direct and indirect equityholders, members, partners, directors, managers, officers, employees and agents of any Seller or its current and future Affiliates (collectively, the “Seller Indemnified Parties” and together with the Acquiror Indemnified Parties, the “Indemnified Parties”) shall be indemnified and held harmless by Acquirors, jointly and severally, for any Losses incurred or sustained by such Seller Indemnified Party based upon, attributable to, resulting from or by reason of (i) the incorrectness, falsity or breach of, as of the date hereof or as of the Closing Date with the same force and effect as though made on and as of such date (except those representations and warranties that expressly relate only to an earlier date, in which case as of such earlier date), any of the Acquiror Fundamental Representations, or (ii) any breach of any covenant or other agreement on the part of Acquirors to be performed in whole or in part after the Closing.

Section 8.3Indemnification Procedure.

(a) Each Indemnified Party agrees that promptly after it becomes aware of facts giving rise to a claim by it for indemnification pursuant toSection 8.2, such Indemnified Party will assert its claim for indemnification underSection 8.2 (each, a “Claim”) by providing a written notice (a “Claim Notice”) within the applicable survival period specified inSection 8.1 to the applicable indemnifying party (the “Indemnifying Party”) specifying, in reasonable detail, to the extent known by such Indemnified Party, the nature and basis for such Claim (e.g., the underlying representation, warranty or covenant alleged to have been breached and the condition or conduct allegedly resulting in such breach). Notwithstanding the foregoing, an Indemnified Party’s delay in sending a Claim Notice will not relieve the Indemnifying Party from Liability hereunder with respect to such Claim except to the extent (and limited solely to the extent) of any material prejudice to the Indemnifying Party by such failure or delay,provided that such Claim Notice is provided within the applicable survival period.

(b) In the event that any Proceeding is instituted or any Claim is asserted by any Third Party in respect of which indemnification may be sought underSection 8.2 and in respect of which the Indemnifying Party has agreed in writing to indemnify the Indemnified Party for all of such Indemnified Party’s Losses (subject to any applicable limitations in thisArticle VIII) (a “Third Party Claim”), the Indemnifying Party will have the right, at such Indemnifying Party’s sole option and expense, to assume the defense of the same including the appointment and selection of counsel on behalf of the Indemnified Party so long as such counsel is reasonably acceptable to the Indemnified Party. If the Indemnifying Party elects to assume the defense of any such Third Party Claim, it shall within 30 days notify the Indemnified Party in writing of its intent to do so;provided,however, that the Indemnifying Party shall not, without the written consent of the Indemnified Party, be entitled to assume or continue to control the defense of any Third Party Claim if (i) the Third Party Claim relates to or arises in connection with any criminal action, (ii) the Third Party Claim seeks an injunction or equitable relief against any Indemnified Party, (iii)

- 47 -

the Third Party Claim has or would reasonably be expected to result in damages in excess of the amounts available for indemnification pursuant toSection 8.5, (iv) the Indemnifying Party has failed or is failing to diligently defend such action in good faith, (v) the Third Party Claim would reasonably be expected to have a material and adverse effect on the Indemnified Party’s business, or (vi) separate representation of the Indemnified Party by counsel is reasonably necessary to avoid a conflict of interest;provided that, for the avoidance of doubt, if the Indemnifying Party is unable to assume or continue to control the defense in any such instances, it shall nonetheless remain responsible for the indemnification obligations hereunder. In all events the Indemnifying Party will have the right to settle or compromise or take any corrective or remedial action with respect to any such Third Party Claim by all appropriate proceedings, which proceedings will be diligently prosecuted by the Indemnifying Party to a final conclusion or settled at the discretion of the Indemnifying Party. The Indemnified Party will be entitled, at its own cost, to participate with the Indemnifying Party in the defense of any such Third Party Claim.

(c) Notwithstanding anything in thisSection 8.3 to the contrary, the Indemnifying Party will not be permitted to settle, compromise, take any corrective or remedial action or enter into an agreed judgment or consent decree or permit a default without the Indemnified Party’s prior written consent, in each case, that (i) does not include as an unconditional term thereof the delivery by the claimant to the Indemnified Party of a binding, irrevocable, written release of any Indemnified Party from all Liability, (ii) provides for any admission of Liability on the part of any Indemnified Party, (iii) requires an admission of guilt or wrongdoing on the part of any Indemnified Party or (iv) imposes any Liability or continuing obligation on, or requires any payment from, any Indemnified Party.

Section 8.4Exclusive Remedy. From and after the Closing, except for any claim based on fraud, the reimbursement and indemnification obligations provided inSection 6.4(e) and thisArticle VIII shall be the sole and exclusive legal remedies of the Parties with respect to this Agreement and the transactions contemplated hereby. Notwithstanding the foregoing, thisSection 8.4 shall not prevent any Party from seeking and obtaining injunctive relief against the other Parties’ activities in breach of this Agreement. In furtherance of the foregoing, each Acquiror hereby waives, from and after the Closing, to the fullest extent permitted by applicable Law, any and all rights, claims and causes of action it may have relating to the subject matter of this Agreement based upon predecessor or successor liability, contribution, tort, strict liability or any Law or otherwise, except for any rights, claims or causes of action under thisArticle VIII or based on fraud.

Section 8.5Limitations.

(a) To the extent that Acquirors would otherwise be entitled to indemnification of any Losses pursuant toSection 8.2, Sellers shall be liable only if the Losses for all claims exceed, in the aggregate, $5,000,000.00 (the “Deductible Amount”), and then Sellers shall only be liable for Losses to the extent of any excess over the Deductible Amount. The aggregate liability of Sellers or Acquirors underSection 8.2 will not exceed (i) with respect to any claim giving rise to a right of indemnification of which notice is given prior to thesix-month anniversary of the Closing Date, $250,000,000.00, or (ii) with respect to any claim giving rise to a right of indemnification of which notice is given after thesix-month anniversary of the Closing Date and prior to the twelve-month anniversary of the Closing Date, the lesser of (A) $125,000,000.00 and (B) (x) $250,000,000.00minus (y) the aggregate amount of claims giving rise to a right of indemnification of which notice is given prior to thesix-month anniversary of the Closing Date.

(b) Each Indemnified Party shall take, and cause its Affiliates to take, commercially reasonable steps to mitigate any Loss for which it would otherwise be entitled to indemnification pursuant to thisArticle VIII upon becoming aware of any event or circumstance that would be reasonably expected to, or does, give rise thereto, including incurring costs only to the minimum extent necessary to remedy the breach that gives rise to such Loss;provided that any reasonable cost incurred by a Party to mitigate any such Loss will be deemed a Loss for purposes of thisArticle VIII.

(c) NOTWITHSTANDING ANYTHING TO THE CONTRARY IN THIS AGREEMENT, NO PARTY TO THIS AGREEMENT NOR ANY AFFILIATE OF A PARTY TO THIS AGREEMENT SHALL BE LIABLE HEREUNDER TO ANY INDEMNIFIED PARTY FOR ANY LOST PROFITS OR PUNITIVE, CONSEQUENTIAL, REMOTE, SPECULATIVE, SPECIAL OR INDIRECT DAMAGES, EXCEPT TO THE EXTENT (I) SUCH LOST PROFITS OR DAMAGES ARE INCLUDED IN ANY ACTION BY A THIRD PARTY AGAINST SUCH INDEMNIFIED PARTY FOR WHICH IT IS ENTITLED TO INDEMNIFICATION UNDER THIS AGREEMENT OR (II) IN THE CASE OF CONSEQUENTIAL, REMOTE OR INDIRECT DAMAGES, OR DAMAGES FOR DIMINUTION OF VALUE RELATIVE TO THE PURCHASE PRICE, SUCH DAMAGES ARE REASONABLY FORESEEABLE.

Section 8.6Tax Treatment of Indemnity Provisions. Each Party, to the extent permitted by applicable Law, agrees to treat any indemnity payments made pursuant to thisArticle VIII as adjustments to the Purchase Price for all U.S. federal and applicable state income and franchise Tax purposes.

Section 8.7Calculation of Losses. In calculating amounts payable to an Indemnified Party, the amount of any indemnified Losses shall be computed net of (a) payments actually recovered by any Indemnified Party under any insurance policy with respect to such Losses net of expenses and (b) any actual recovery by any Indemnified Party from any Person with respect to such Losses net of expenses. Each Indemnified Party shall use commercially reasonable efforts to pursue reimbursement for Losses, including under insurance policies and other indemnity arrangements. Notwithstanding anything to the contrary in this Article VIII, for the purposes of determining the amount of Losses incurred or suffered with respect to a breach of representations or warranties, any reference to “material,” “materially,” “TGE Entities Material Adverse Effect,” “Seller Material Adverse Effect” or “Acquiror Material Adverse Effect” will be disregarded for the purposes of thisArticle VIII.

Section 8.8No Duplication. In no event shall any Indemnified Party be entitled to recover any Losses under one Section or provision of this Agreement to the extent such Losses were already recovered by such Indemnified Party, nor shall its insurer or indemnitor be entitled to any kind of subrogation or substitution which would give it the right to make a claim against the Indemnifying Party.

(c) by Acquirors, if a Major Seller shall have breached or failed to perform any of its representations, warranties, covenants or agreements set forth in this Agreement, or if any representation or warranty of a Major Seller shall have become untrue, in either case, such that the conditions set forth inSection 7.2(a) or (b) would not be satisfied and such breach is incapable of being cured or, if capable of being cured, shall not have been cured by the date that is the earlier of (i) 30 days after the applicable Major Sellers’ receipt of written notice of such breach and (ii) the Outside Date;provided,however, that the right to terminate this Agreement under thisSection 9.1(c) shall not be available to Acquirors if any Acquiror is then in material breach of its representations, warranties or covenants hereunder;

(d) by the Major Sellers, if Acquirors shall have breached or failed to perform any of their respective representations, warranties, covenants or agreements set forth in this Agreement (other than pursuant toSection 6.4(f)), or if any representation or warranty of Acquirors shall have become untrue, in either case such that the conditions set forth inSection 7.3(a) or (b) would not be satisfied and such breach is incapable of being cured or, if capable of being cured, shall not have been cured by the date that is the earlier of (i) 30 days after the applicable Acquiror’s receipt of written notice of such breach and (ii) the Outside Date;provided,however, that the right to terminate this Agreement under thisSection 9.1(d) shall not be available to the Major Sellers if any Major Seller is then in material breach of its representations, warranties or covenants hereunder;

(e) by the Major Sellers, if (i) at least two Business Days have elapsed since the Inside Date and all of the conditions provided for inSections 7.1 and7.2 have been satisfied or irrevocably waived (other than those conditions which by their terms are only capable of being satisfied at the Closing,provided that such conditions are capable of being satisfied if the Closing Date were the date of the provision of the notice described inclause (ii) below), (ii) the Major Sellers have delivered irrevocable written notice to Acquirors to the effect that (x) all of the conditions provided for inSections 7.1 and7.2 have been satisfied or irrevocably waived (other than those conditions which by their terms are only capable of being satisfied at the Closing,provided that such conditions are capable of being satisfied if the Closing Date were the date of the provision of such notice) and (y) Sellers are, subject to Acquirors’ performance of their obligations, ready, willing and able to consummate the Closing pursuant toSection 2.3 and (iii) Acquirors fail to consummate the transactions contemplated by this Agreement within three Business Days of the later of (x) the date on which the Closing was supposed to have occurred pursuant toSection 2.3 and (y) the date on which the notice referenced in thisSection 9.1(e) is delivered; or

- 51 -

(f) by the Major Sellers or Acquirors, in the event that the Closing does not occur on or before March 29, 2019 (such date, the “Outside Date”);provided, in any such case,that such failure of the Closing to occur is not (i) in the case of a termination by the Major Sellers, due to the failure of a Major Seller to perform and comply in all material respects with the covenants and agreements to be performed or complied with by such Seller prior to the Closing and (ii) in the case of a termination by the Acquirors, due to the failure of any Acquiror to perform and comply in all material respects with the covenants and agreements to be performed or complied with by such Acquiror prior to the Closing.

Section 9.2Procedure Upon Termination. In the event of termination of this Agreement by Acquirors or Sellers, or both, pursuant toSection 9.1, written notice thereof shall forthwith be given to the other Parties, and this Agreement shall terminate, and the purchase of the Subject Interests hereunder shall be abandoned, without further action by Acquirors or Sellers.

Section 9.3Effect of Termination; Termination Fees.

(a) In the event that this Agreement is terminated as provided inSection 9.1, then this Agreement shall forthwith become null and void and of no further force and effect (except for the provisions ofSection 6.4(e), thisSection 9.3,Article X,Section 11.3,Section 11.5,Section 11.6 andExhibit A) and each of the Parties shall be relieved of its duties and obligations arising under this Agreement after the date of such termination and the Parties shall have no further Liability hereunder (except pursuant toSection 6.4(e), thisSection 9.3 andSection 11.6);provided, subject toSection 9.3(d), that nothing in thisSection 9.3 shall relieve Sellers of any Liability for fraud or a willful breach of this Agreement.

(b) In the event that this Agreement is terminated by the Major Sellers pursuant toSection 9.1(d) orSection 9.1(e), or is terminated by the Major Sellers or Acquirors pursuant toSection 9.1(f) at a time when Sellers could have terminated the Agreement pursuant toSection 9.1(d) orSection 9.1(e), then, in any such case, Acquirors shall promptly, but in no event later than ten Business Days after the date of such termination, pay or cause to be paid to Sellers or their designee an amount in cash equal to $164,643,001 (the “ReverseTermination Fee”) by wire transfer of immediately available funds to one or more accounts designated by Sellers in writing.

(c) It is agreed that the Reverse Termination Fee is an integral part of this Agreement and without the Reverse Termination Fee, Acquirors and Sellers would not have entered into this Agreement. The Reverse Termination Fee is intended to be liquidated damages (and not a penalty). Accordingly, if Acquirors fail to pay the Reverse Termination Fee pursuant toSection 9.3(b) on or prior to the date such amounts are due hereunder, and, in order to obtain such payment, Sellers commence a Proceeding that results in a final, nonappealable judgment against Acquirors for the payment of the Reverse Termination Fee pursuant toSection 9.3(b), Acquirors shall pay, or cause to be paid, to Sellers, interest on such amount at an annual rate equal to the

- 52 -

prime rate as published in the Wall Street Journal, Eastern Edition, in effect on the date such amounts were originally due hereunder which shall accrue from such date through the date such payment is actually delivered to Sellers or their designee, and the costs and expenses (including reasonable attorneys’ fees and expenses) incurred by Sellers in connection with such Proceeding.

(d) The Parties agree that the monetary remedies set forth inSection 9.3(b) (when and if available under the express terms hereof) and the specific performance remedies set forth inSection 11.6 shall be the sole and exclusive remedies (whether at law, in equity, in contract, in tort or otherwise, whether by or through piercing of the corporate or partnership veil, by or through a claim by or on behalf of any Person) of Sellers and any of their respective former, current and future Affiliates (which, for the purposes of thisSection 9.3(d), shall be deemed to include the TGE Entities), each of their former, current and future partners, members, equityholders and Representatives, and each of their respective heirs, executors, administrators, successors and assigns, for any Losses or Liabilities suffered or incurred by any such Person with respect to this Agreement, the other Transaction Documents and the transactions contemplated hereby and thereby as a result of the failure of the Closing to occur or the transactions contemplated by the Transaction Documents to be consummated for any or no reason or, in the event of a failure of the Closing to occur or the transactions contemplated by the Transaction Documents to be consummated for any reason or for no reason, for any breach by any Acquiror of this Agreement. Without limiting the rights of Acquirors under the Debt Commitment Papers, upon the payment of the Reverse Termination Fee following a failure of the Closing to occur or the transactions contemplated by the Transactions to be consummated, no Acquiror, AcquirorNon-Recourse Party or Financing Source shall have any liability or obligation in connection with, relating to or arising out of this Agreement, the Transaction Documents or the transactions contemplated hereby and thereby. Under no circumstance shall any Person be permitted or entitled both to obtain specific performance pursuant toSection 11.6 and to receive all or any portion of the Reverse Termination Fee.

(c) EACH PARTY IRREVOCABLY AND UNCONDITIONALLY WAIVES, TO THE FULLEST EXTENT PERMITTED BY APPLICABLE LAW, ALL RIGHT IT MAY HAVE TO A TRIAL BY JURY IN RESPECT OF ANY PROCEEDING DIRECTLY OR INDIRECTLY ARISING OUT OF OR IN CONNECTION WITH THIS AGREEMENT AND ANY OTHER TRANSACTION DOCUMENT EXECUTED IN CONNECTION HEREWITH OR THE TRANSACTIONS CONTEMPLATED HEREBY OR THEREBY. EACH PARTY CERTIFIES AND ACKNOWLEDGES THAT (I) NO REPRESENTATIVE OF ANY OTHER PARTY HAS REPRESENTED, EXPRESSLY OR OTHERWISE, THAT SUCH PARTY WOULD NOT SEEK TO ENFORCE THE FOREGOING WAIVER IN THE EVENT OF A PROCEEDING, (II) SUCH PARTY HAS CONSIDERED THE IMPLICATIONS OF THIS WAIVER, (III) SUCH PARTY MAKES THIS WAIVER VOLUNTARILY AND (IV) SUCH PARTY HAS BEEN INDUCED TO ENTER INTO THIS AGREEMENT BY, AMONG OTHER THINGS, THE MUTUAL WAIVERS AND CERTIFICATIONS IN THISSECTION 10.1.

Section 11.4Assignment. This Agreement shall be binding upon and inure to the benefit of the Parties and their successors and permitted assigns. No Party may assign this Agreement or any rights or obligations hereunder without the prior written consent of each Acquiror and Major Seller;provided,however, that each Acquiror shall be permitted to assign all of its rights, benefits and obligations under this Agreement (a) to one or more Affiliates of such Acquiror and (b) to its Financing Sources in connection with the grant of a security interest in the collateral for the Debt Financing, in each case, without the prior written consent of Sellers, but such Acquiror shall promptly give Sellers written notice of any such assignment and such Acquiror shall not be released from any of its obligations hereunder. Any attempted assignment or transfer in violation of this Agreement shall be null, void and ineffective.

- 57 -

Section 11.5Expenses. Except as otherwise set forth in this Agreement, each Party shall pay its own costs and expenses (including legal, accounting, financial advisory and consulting fees and expenses) incurred by such Party in connection with the negotiation and consummation of the transactions contemplated by this Agreement and the other Transaction Documents, except that Acquirors shall pay all costs and expenses (including fees payable in connection therewith) incurred in connection with obtaining the TEP Waiver.

Section 11.6Specific Performance; Acquiror Liability Cap.

(a) The Parties acknowledge and agree that a failure of any Acquiror, on the one hand, or any Seller, on the other hand, to perform their obligations set forth in this Agreement or other breach of this Agreement would cause irreparable damage to Sellers or Acquirors, as applicable, and Sellers or Acquirors, as applicable, would not have an adequate remedy at Law. Therefore, the obligations of Acquirors and Sellers under this Agreement, including Sellers’ obligation to sell the Subject Interests to Acquirors and Acquirors’ obligation to purchase the Subject Interests from Sellers, in each case on the terms and subject to the conditions set forth in this Agreement, shall be enforceable by a decree of specific performance issued by any court of competent jurisdiction, and appropriate injunctive relief may be applied for and granted in connection therewith. Until such time as this Agreement is validly terminated and the Reverse Termination Fee is paid, such remedies shall be cumulative and not exclusive and shall be in addition to any other remedies which any Party may have under this Agreement or otherwise, including the right of Sellers to pursue both a grant of specific performance and payment of the Reverse Termination Fee;provided,however, that in no event shall Sellers be entitled to receive both (x) a grant of specific performance and (y) payment of the Reverse Termination Fee. Notwithstanding the foregoing, it is explicitly agreed that the right of Sellers to specific performance or other equitable remedies in connection with enforcing Acquirors’ obligation to cause the Equity Financing to be funded and to consummate the transactions contemplated by this Agreement and the other Transaction Documents (but not the right of Sellers to specific performance or other equitable remedies for obligations other than with respect to the Equity Financing or such consummation) shall be subject to the requirements that (i) the Inside Date has occurred and all of the conditions set forth inSection 7.1 andSection 7.2 shall have been and shall continue to be satisfied (other than those conditions that by their terms are to be satisfied by actions taken at Closing but subject to their being reasonably expected to be satisfied at Closing) at the time when the Closing would be required to occur, (ii) the Debt Financing either has been funded in accordance with the terms of the Debt Financing Documents or will be funded in accordance with the terms of the Debt Financing Documents at the Closing if the Equity Financing is funded at the Closing, (iii) the Major Sellers shall have irrevocably confirmed to Acquirors in writing that, if specific performance is granted and the Equity Financing and Debt Financing are funded, then the Major Sellers would take such actions that are required of them by this Agreement to cause the Closing to occur in accordance with its terms and (iv) Acquirors fail to complete the Closing within three Business Days following the delivery of the confirmations pursuant to the precedingclause (iii).

- 58 -

(b) Notwithstanding anything to the contrary in this Agreement, but excluding amounts owed by Acquirors pursuant toSection 6.4(e) andSection 11.5, the maximum liability of Acquirors and the Financing Sources for Liabilities or Losses incurred by Sellers and any of their respective former, current and future Affiliates (which, for the purposes of thisSection 11.6(b), shall be deemed to include the TGE Entities), each of their former, current and future partners, members, equityholders and Representatives, and each of their respective heirs, executors, administrators, successors and assigns, in each case, relating to the failure of the Closing to occur or the transactions contemplated by the Transaction Documents to be consummated, breach of this Agreement by any Acquiror, the Equity Commitment Letter, the Limited Guarantee and the transactions contemplated by the Transaction Documents shall be limited to an amount equal to the Reverse Termination Fee, and in no event shall Sellers or any of their Affiliates seek any amount in excess of the Reverse Termination Fee in connection with this Agreement, the Equity Commitment Letter, the Limited Guarantee and the transactions contemplated by the Transaction Documents or in respect of any other document or theory of law or equity or in respect of any oral representations made or alleged to be made in connection herewith or therewith, whether at law or in equity, in contract, tort or otherwise.

Section 11.7Entire Agreement. This Agreement (including the Schedules and Exhibits hereto), together with each of the other Transaction Documents, constitute the entire understanding and agreement among the Parties with respect to the subject matter hereof and supersede any and all prior or contemporaneous discussions, agreements and understandings, whether written or oral.

Section 11.8Severability. Whenever possible, each provision of this Agreement shall be interpreted in such manner as to be effective and valid under applicable Law, but if any provision or portion of this Agreement is held to be invalid, illegal or unenforceable in any respect under any applicable Law in any jurisdiction by any applicable Governmental Authority, (a) such invalidity, illegality or unenforceability shall not affect the validity, legality or enforceability of any other provision of this Agreement in such jurisdiction or affect the validity, legality or enforceability of any provision in any other jurisdiction, (b) such provision shall be invalid, illegal or unenforceable only to the extent strictly required by such Governmental Authority, (c) to the extent any such provision is deemed to be invalid, illegal or unenforceable, each Seller and Acquiror agrees that it shall use its commercially reasonable efforts to cause such Governmental Authority to modify such provision so that such provision shall be valid, legal and enforceable as originally intended to the greatest extent possible and (d) to the extent that the Governmental Authority does not modify such provision, each Seller and Acquiror agrees that they shall endeavor in good faith to exercise or modify such provision so that such provision shall be valid, legal and enforceable as originally intended to the greatest extent possible.

Section 11.9Disclosure Schedules. The inclusion of any information (including dollar amounts) in any section of any schedule delivered by Sellers to Acquirors in connection with this Agreement (the “Disclosure Schedules”) shall not be deemed to be an admission or acknowledgment by Sellers that such information is required to be listed on such section of the relevant Disclosure Schedule (except to the extent this Agreement expressly states that such applicable section of the Disclosure Schedules is required to include such information) or is material to or outside the ordinary course of the business of the applicable Person to which such disclosure relates. Each disclosure item set forth in the Disclosure Schedules shall relate to the specific Section of the Agreement that corresponds to the number of such Schedule and to any

- 59 -

other Section of this Agreement to which it is reasonably apparent on the face of such disclosure that such disclosure relates. The information contained in this Agreement, the Exhibits hereto and the Disclosure Schedules is disclosed solely for purposes of this Agreement, and no information contained herein or therein shall be deemed to be an admission by any Party to any Third Party of any matter whatsoever (including any violation of Law or breach of contract).

Section 11.10Third Party Beneficiaries. This Agreement shall be binding upon and, except as provided below, inure solely to the benefit of the Parties and their respective successors and permitted assigns. None of the provisions of this Agreement shall be for the benefit of or enforceable by any Person other than the Parties, including any creditor of any Party or any of their Affiliates, except (a)Section 6.4(e),Section 6.9 andArticle VIII shall inure to the benefit of the Persons referred to therein, (b)Section 11.14 andSection 11.16 shall inure to the benefit of the Persons referred to therein, (c) the Financing Sources are intended third-party beneficiaries ofSection 9.3(d),Section 10.1(b),Section 11.1,Section 11.2, thisSection 11.10,Section 11.13 andSection 11.6(b) and shall be entitled to enforce their respective rights under such provisions pursuant to which they are entitled to benefits, (d) the Persons listed onSchedule 6.3(h) are intended third-party beneficiaries ofSection 6.3(h) (and, for the avoidance of doubt, the correspondingSchedule 6.3(h)) andSection 6.13(a) and shall be entitled to enforce their respective rights under such provisions pursuant to which they are entitled to benefits, and (e) the Persons listed onSchedule 6.13(c) are intended third-party beneficiaries ofSection 6.13(c) (and, for the avoidance of doubt, the correspondingSchedule 6.13(c)) and shall be entitled to enforce their respective rights under such provisions pursuant to which they are entitled to benefits. Notwithstanding anything to the contrary contained herein,Section 9.3(d),Section 10.1(b),Section 11.1,Section 11.2,Section 11.6(b), thisSection 11.10,Section 11.13 and the definition of “Financing Sources” (and any provision of this Agreement to the extent a modification, waiver or termination of such provision would modify the substance ofSection 9.3(d),Section 10.1(b),Section 11.1,Section 11.2,Section 11.6(b), thisSection 11.10 andSection 11.13) may not be modified, waived or terminated by Acquirors in a manner that is adverse in any respect to the Financing Sources without the prior written consent of the parties to the Debt Commitment Papers. Other than as set forth in the prior sentence: (i) the Parties reserve the right to amend, modify, terminate, supplement or waive any provision of this Agreement or this entire Agreement, in accordance withSection 11.1 andSection 11.2, as applicable, without the consent or approval of any other Person and (ii) no Party shall have any direct liability to any permitted third party beneficiary, nor shall any permitted third party beneficiary have any right to exercise any rights hereunder for such third party beneficiary’s benefit except to the extent such rights are brought, exercised and administered by a Party. No Person other than the Parties shall obtain any right under any provision of this Agreement or shall by reason of any such provision make any claim in respect of any Liability (or otherwise) against any other Parties.

Section 11.11Facsimiles; Electronic Transmission; Counterparts. This Agreement may be executed by facsimile or other electronic transmission (including scanned documents delivered by email) by any Party and such execution shall be deemed binding for all purposes hereof, without delivery of an original signature being thereafter required. This Agreement may be executed in one or more counterparts, each of which, when executed, shall be deemed to be an original and all of which together shall constitute one and the same document.

- 60 -

Section 11.12Time of Essence. Time is of the essence in the performance of this Agreement.
