Notwithstanding anything in this Agreement to the contrary, (i) in fulfilling its obligations under the foregoing provisions of this Section 7.1(e)(v) Buyer shall not be required to take any action that would result in a Material Adverse Effect; and (ii) no Seller shall be required to, and Buyer shall not, in connection with obtaining any consents or approvals hereunder, consent to (x) the taking of any action or the imposition of any terms, conditions, limitations or standards of service the effectiveness or consummation of which is not conditional upon the occurrence of Closing or (y) the imposition of any terms, conditions or limitations on or with respect to any Seller, any of its respective Affiliates, any of its respective businesses or any of the benefits to any Seller and its respective Affiliates of the transactions contemplated hereunder.

7.7 Tax Matters.

(a)Sellers shall file or cause to be filed all Tax Returns for U.S. federal or state income Taxes required to be filed by the Project Companies for all taxable periods ending on or prior to the Closing Date, regardless of whether such Tax Returns are due before or after Closing and shall pay all Taxes shown as due on such Tax Returns (except for those Taxes included as Current Liabilities in the final computation of Net Working Capital). Buyer shall assist Sellers in the filing of such Tax Returns. Sellers shall file or cause to be filed all other Tax Returns of the Project Companies that are due before the Closing Date. Buyer shall file or cause to be filed all other Tax Returns of the Project Companies.

(b)▇▇▇▇▇▇ ▇▇▇▇▇▇▇ shall file or cause to be filed all Tax Returns for U.S. federal or state income Taxes required to be filed by the ▇▇▇▇▇▇ Acquired Companies for all taxable periods ending on or prior to the Closing Date, regardless of whether such Tax Returns are due before or after Closing, and shall pay any Taxes shown as due on such Tax Returns. Buyer shall assist ▇▇▇▇▇▇ ▇▇▇▇▇▇▇ in the filing of such Tax Returns. ▇▇▇▇▇▇ ▇▇▇▇▇▇▇ shall file or cause to be filed all other Tax Returns of the ▇▇▇▇▇▇ Acquired Companies that are due before the Closing Date. Buyer shall file or cause to be filed all other Tax Returns of the ▇▇▇▇▇▇ Acquired Companies.

(c)The Sellers shall pay all Taxes of the Project Companies and ▇▇▇▇▇▇ ▇▇▇▇▇▇▇ shall pay all Taxes of the ▇▇▇▇▇▇ Acquired Companies attributable to a Pre-Closing Date Straddle Period (except for those Taxes included in Current Liabilities in the final computation of Net Working Capital). For purposes of this Agreement, the portion of Tax with respect to the income, property or operations of a taxpayer that is attributable to any tax period of such taxpayer that includes but does not end on the Closing Date (a “Straddle Period”) will be apportioned between the portion of such Straddle Period that extends before the Closing Date through the Closing Date (the “Pre-Closing Date Straddle Period”) and the portion of the Straddle Period that extends from the day after the Closing Date to the end of the Straddle Period in accordance with this Section 7.7(c). The portion of such Tax attributable to the Pre-Closing Date Straddle Period will (i) in the case of any Taxes other than income Taxes, sales or use taxes, value-added taxes, employment taxes, or withholding taxes, be deemed to be the amount of such Tax for the entire taxable period multiplied by a fraction, the numerator of which is the number of days in the Pre-Closing Date Straddle Period and denominator of which is the number of days in the Straddle Period, and (ii) in the case of any income Taxes, sales or use taxes, value-added taxes, employment taxes, or withholding taxes, be deemed equal to the amount that would be payable if the Straddle Period ended on and included the Closing Date. To the extent that any Tax for a Straddle Period is based on the greater of a Tax on net income, on the one hand, and a Tax measured by net worth or some other basis not otherwise measured by income, on the other hand, the portion of such Tax related to the Pre-Closing Date Straddle Period will be determined based on the foregoing and based on the manner in which the actual Tax liability for the entire Straddle Period is determined.

(d)Each of Sellers and Buyer agree to file all applicable U.S. federal income Tax Returns consistent with Closing not causing a termination of the Company for U.S. federal income Tax purposes, and take no inconsistent position for any U.S. federal income Tax purpose, except as otherwise required by applicable Law or a determination within the meaning of Section 1313(a) of the Code.

(e)In the event that any Transfer Taxes are imposed on the transactions contemplated by this Agreement, each of Sellers and Buyer shall pay any Transfer Taxes imposed on it by Law as a result of the transactions contemplated by this Agreement, but, notwithstanding such requirement at Law, Buyer shall be responsible for the payment of all such Transfer Taxes. Accordingly, if any such Seller is required by Law to pay any such Transfer Taxes, Buyer shall promptly reimburse such Seller for all such amounts. Each Seller and Buyer shall timely file their own Tax Returns relating to Transfer Taxes as required by Law and shall notify the other Parties when such filings have been made. Each Seller and Buyer shall cooperate and consult with each other prior to filing such Tax Returns to ensure that all such returns are filed in a consistent manner.

(f)All Tax Returns prepared or filed after the Closing Date by the Sellers or the ▇▇▇▇▇▇ ▇▇▇▇▇▇▇ shall be submitted to Buyer at least 10 Business Days prior to the due date thereof and shall be prepared in accordance with the past practice of the taxpayer to whom the Tax Return relates (except to the extent otherwise required by applicable Law).

(g)Each party will, and each party will cause its applicable Affiliates to, cooperate in all reasonable respects with respect to Tax matters and provide one another with such information as is reasonably requested to enable the requesting party to complete and file all Tax Returns it may be required to file (or cause to be filed) with respect to the Project Companies or the ▇▇▇▇▇▇ Acquired Companies, to respond to Tax audits, inquiries or other Tax Proceedings and to otherwise satisfy Tax requirements. Such cooperation also will include promptly forwarding copies (to the extent related thereto) of relevant Tax notices, forms or other communications received from or sent to any Taxing Authority.

(h)The Sellers and Buyer shall retain or cause to be retained, until the applicable statutes of limitations (including any extensions and carryovers) have expired, copies of all Tax Returns related to the Project Company and the ▇▇▇▇▇▇ Acquired Companies for all Tax periods beginning before the Closing Date, together with supporting work schedules and other records or information that may be relevant to such Tax Returns.

7.8 Public Announcements. This Agreement and all documents and information furnished by any Seller to Buyer on or after the date of this Agreement and prior to Closing (including all information gained by Buyer or its Representatives in exercising Buyer’s rights of access pursuant to Section 6.2) shall be subject to the Confidentiality Agreement. Notwithstanding anything in this Agreement or the Confidentiality Agreement to the contrary, each Seller may disclose information regarding this Agreement and the transactions contemplated hereby to its direct and indirect investors, limited partners and other Affiliates; provided that any such Person to whom any such information is disclosed is obligated to, except as otherwise required by application of law or regulation, maintain such information in confidence. No Party shall make any public announcement or issue any public communication regarding this Agreement or the transactions contemplated hereby without first obtaining the prior written consent of the other Parties, except if such announcement or other communication is required by applicable Law, in which case, to the extent permitted by Law, the disclosing Party shall use its commercially reasonable efforts to coordinate or communicate such announcement or communication with the other Parties prior to announcement or issuance.

7.9 Updating. From time to time prior to Closing, Sellers may at their option supplement or amend and deliver updates to (or add schedules to) the Schedules as necessary to complete or correct any information in such Schedules with respect to any representation or warranty in Article III, Article IV or V. Any such update made pursuant to this Section 7.9 shall be deemed to cure any inaccuracy of any representation or warranty made in this Agreement except to the extent such update would reasonably be expected to result in a Material Adverse Effect or a material adverse effect on the ability of any Seller to consummate the transactions contemplated hereby.

7.10 Retention and Severance Benefits. At or immediately prior to Closing, Sellers shall fund an escrow account with cash in an amount equal to the aggregate potential liability of SourceGas LLC as of the Closing Date under the Retention and Severance Letters. The funds in the escrow account shall be used to pay benefits under the Retention and Severance Letters as such benefits become due and payable in accordance with that certain Escrow Agreement by and among each Seller and SourceGas LLC, substantially in the form attached hereto as Exhibit C (subject to any revisions thereto that may be reasonably requested by the Escrow Agent thereunder) (the “Escrow Agreement”). Notwithstanding anything herein to the contrary, (i) amounts paid from the escrow account shall only be paid upon written approval of Sellers and SourceGas LLC in accordance with the terms of the Escrow Agreement and (ii) any funds remaining in the escrow account upon the earlier of 14 months following Closing and the satisfaction of all benefits to be paid under the Retention and Severance Letters shall be paid to Sellers in accordance with the terms of the Escrow Agreement.

7.12 Use of Certain Names. Within 15 days following Closing, Buyer shall cause the Acquired Companies to cease using the words “▇▇▇▇▇▇”, “ASC”, “Aircraft Services Corporation”, “General Electric” and “GE” and any word or expression similar thereto or constituting an abbreviation, derivation or extension thereof (the “Sellers’ Marks”), including eliminating the Sellers’ Marks from the Property and the Assets of the Acquired Companies and disposing of any unused stationery and literature of any Acquired Company bearing the Sellers’ Marks. Thereafter, Buyer shall not, and shall cause the Acquired Companies and their respective Affiliates not to, use the Sellers’ Marks or any other logos, trademarks, trade names or other Intellectual Property belonging to Sellers or any Affiliate thereof. Buyer acknowledges that it, its Affiliates and, from and after Closing, the Acquired Companies have no rights whatsoever to use such Intellectual Property.

7.13 Indebtedness and Distributions. Notwithstanding anything in this Agreement to the contrary:

(a)At or prior to Closing, in their sole discretion, Sellers may, or may cause the Project Companies to, repay or cash collateralize effective as of Closing all or any portion of any indebtedness for borrowed money of the Project Companies; and

(b)Sellers shall have the right to cause the Project Companies to, and the ▇▇▇▇▇▇ ▇▇▇▇▇▇▇ shall have the right to cause the ▇▇▇▇▇▇ Acquired Companies to, pay cash dividends, and/or make cash distributions to Sellers or their respective Affiliates at any time prior to Closing.

7.14 Insurance. Buyer shall be solely responsible for providing insurance to the Acquired Companies for any Claims made after Closing with respect to any Acquired Company or any Asset of the Acquired Companies regardless of when the event or occurrence relating to the Claim arose. If any Losses occur prior to Closing that relate to the Acquired Companies and a Claim associated with any such Losses can reasonably be made against one or more third parties, including under any insurance policies listed on Schedule 5.4 or any renewal thereof, Sellers shall (or if such Claim relates solely to the ▇▇▇▇▇▇ Acquired Companies, the ▇▇▇▇▇▇ ▇▇▇▇▇▇▇ shall), both before and after Closing, be entitled to control such Claim and, if any Seller so elects to control such Claim, Buyer shall cause the Project Companies to cooperate in connection therewith. If any insurance proceeds or other third party reimbursements are received by Buyer or the Acquired Companies following Closing in respect of any such Losses, Buyer shall, and shall cause the Acquired Companies to, as applicable, promptly pay to Sellers all such proceeds in such proportions as Seller shall direct in writing.

7.15 Further Assurances. Subject to the terms and conditions of this Agreement, at any time or from time to time after Closing, at any Party’s request and without further consideration, the other Parties shall (and in the case of Buyer, Buyer shall, and shall cause the applicable Acquired Companies 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.

7.16 Continuing Employees. A “Continuing Employee” is each employee of the Project Companies on the Closing Date that is not subject to a collective bargaining agreement. Until the earlier of one year after the Closing Date or the date the Continuing Employee ceases to be employed by Buyer or an Affiliate of Buyer, Buyer shall, or shall cause an Affiliate of Buyer to, provide each Continuing Employee with: (i) base salary or hourly wage rate that is no less than the base salary or hourly wage rate provided by the Project Companies immediately prior to Closing; (ii) bonus and incentive opportunities that are no less than the bonus incentive opportunities, if any, provided by the Project Companies immediately prior to Closing; and (iii) employee benefits that are substantially the same, in the aggregate, as the employee benefits provided by the Project Companies Benefit Plans immediately prior to Closing. If Buyer or an Affiliate of Buyer chooses to terminate any Project Companies Benefit Plan and provide employee benefits pursuant to the plans of Buyer or an Affiliate of Buyer, each Continuing Employee shall receive credit under such plans for eligibility and vesting purposes and for any severance or paid time off benefit plans only for benefit determination purposes for his or her service with the Project Companies and any predecessor employer, provided, however, that such service shall not be recognized to the extent that (x) such recognition would result in a duplication of benefits for the same period of service or (y) such service was not recognized under the corresponding Project Companies Benefit Plan. In addition, and without limiting the generality of the foregoing, (1) each Continuing Employee shall be immediately eligible to participate, without any waiting time, in any and all of Buyer’s or its Affiliates’ employee benefit plans (each such plan, a “Buyer Plan”) to the extent coverage under any such Buyer Plan replaces coverage under a comparable Project Companies Benefit Plan in which the Continuing Employee participated immediately prior to the replacement of the Project Companies Benefit Plan by the Buyer Plan (each such plan, a “New Plan”), and (2) if a New Plan replaces a Project Companies Benefit Plan on a date other than the last day of the plan year for such Project Companies Benefit Plan, Buyer shall cause any eligible expenses incurred by any Continuing Employee and his or her covered dependents during the portion of the plan year ending on the date such participation in the New Plan begins, to be taken into account under such New Plan for purposes of satisfying all deductible, coinsurance and out-of-pocket requirements applicable to such Continuing Employee and his or her covered dependents for the plan year in which such participation begins as if such amounts had been paid in accordance with such New Plan.

This Section 7.16 shall be binding upon and inure solely to the benefit of each of the Parties, and nothing in this Section 7.16, express or implied, shall confer upon any other Person any rights or remedies of any nature whatsoever under or by reason of this Section 7.16. The Parties acknowledge and agree that nothing in this Agreement shall (i) amend, or be deemed to amend, any Benefit Plan or any other employee benefit or compensation plan, program, policy, practice or arrangement or restrict any authority to amend or terminate any of the foregoing, (ii) provide any other Person with any right, benefit or remedy with regard to any Benefit Plan or other employee benefit or compensation plan, program, policy, practice, or otherwise, (iii) provide any other Person (including any Continuing Employee) with the right to continued employment with any Project Company, Buyer or any of their Affiliates, or (iv) restrict any Project Company, Buyer or any of their Affiliates from terminating any Person’s employment at any time (subject to the Project Company’s standard practices and policies regarding severance, if any, in effect as of the Closing).

7.17 Cooperation with Financing. From the date hereof until the earlier of the Closing Date and the date this Agreement is terminated in accordance with its terms, the Sellers shall use their commercially reasonable efforts to cooperate, and to cause the Acquired Companies and the Sellers’ and Acquired Companies’ respective officers, employees and advisors, including legal and accounting, to cooperate, with Buyer and its Affiliates in connection with the arrangement of the third-party financing contemplated by the Commitment Letter (such third-party financing, the “Financing”) to pay a portion of the Purchase Price, including (i) furnishing financial and other pertinent and customary information relating to the Acquired Companies and their businesses to Buyer, Buyer’s Affiliates and the Financing Sources, on a confidential basis, to the extent reasonably requested by Buyer or its Affiliates to assist in preparation of customary offering or information documents or marketing materials to be used for the completion or marketing of the Financing, including, without limitation, all financial statements and financial and other data and information of the type and form required by Regulation S-X under the Securities Act of 1933 and of the type and form customarily included in a registration statement on Form S-1 for a non-reporting company under the Securities Act of 1933 for a public offering of debt or equity securities, all other data that would be necessary for the underwriter of such offering to receive customary “comfort” (including “negative assurance” comfort) from the Acquired Companies’ independent accountants in connection with such offering, (ii) using commercially reasonable efforts to obtain from the Acquired Companies’ independent accountants comfort letters (and consents of such accountants for use of their reports in any materials relating to the Financing and in connection with any filings required to be made by Buyer pursuant to the Securities Act of 1933 or the Securities Exchange Act of 1934, as amended) customarily provided with respect to financial information of an acquired business in a public offering of debt or equity securities; and (iii) providing authorization letters to the Financing Sources authorizing the distribution of information to prospective lenders or investors and containing a representation to the Financing Sources that the public side versions of such documents, if any, do not include material non-public information about the Acquired Companies or their respective securities. None of Sellers, the Acquired Companies or their respective officers, employees, or advisors shall be required to take any action that would materially interfere with its normal business operations or subject it to actual or potential liability, to take any action that would violate an attorney-client privilege, to bear any cost or expense or to pay any commitment or other similar fee or make any other payment or incur any other liability or provide or agree to provide any indemnity in connection with the Financing or any of the foregoing. Buyer shall, promptly upon request by Sellers or the applicable Acquired Company, reimburse the applicable Sellers or Acquired Company for all documented and reasonable out-of-pocket costs incurred by the applicable Sellers or Acquired Company in connection with this Section 7.17. Buyer shall indemnify and hold harmless Sellers, the Acquired Companies, and its and their respective officers, employees, and advisors from and against any and all liabilities or losses suffered or incurred by them in connection with the cooperation and information provided by such Persons pursuant to this Section 7.17.

7.18 Financing.

(a)Buyer shall use its commercially reasonable efforts to take, or cause to be taken, all actions and to do, or cause to be done, all things necessary, proper or advisable to cause the Financing to, until the earlier of Closing or the valid termination of this Agreement, be available to Buyer upon the terms and conditions set forth in the Commitment Letter, including (i) taking actions to enforce its rights against the lenders and other persons providing the Financing to fund such Financing and (ii) using its commercially reasonable efforts to (A) maintain in effect the Commitment Letter, (B) satisfy on a timely basis all conditions applicable to Buyer obtaining the Financing, and (C) enter into definitive agreements with respect thereto on terms and conditions contained in the Commitment Letter. Buyer shall not agree to or permit any amendment, supplement or other modification of, or waive any of its rights under, the Commitment Letter or any definitive agreements related to the Financing, if such amendment, supplement, modification or waiver would be reasonably expected to prevent, delay or hinder Buyer’s ability to consummate the transactions contemplated hereby, in each case, without Sellers’ prior written consent. Buyer shall promptly furnish to Sellers a complete copy of any amendment, supplement or other modification to the Commitment Letter and a full description of any waiver of Buyer’s rights under the Commitment Letter, as applicable.

(b)In the event that any portion of the Financing becomes unavailable in the manner or from the sources contemplated in the Commitment Letter, (i) Buyer shall promptly notify Sellers, and (ii) Buyer shall use its commercially reasonable efforts to obtain alternative financing from alternative sources, on terms, taken as whole, that are not materially less beneficial to Buyer than those contemplated by the Commitment Letter, would not involve any material conditions to funding the Financing that are not contained in the Commitment Letter and would not reasonably be expected to prevent, materially impede or materially delay the consummation of the transactions contemplated hereby, as promptly as practicable following the occurrence of such event. In the event that alternative financing shall be secured pursuant to this Section 7.18(b), Buyer shall comply with the covenants in Section 7.18(a) with respect to such alternative financing and shall promptly furnish to Sellers the commitment letter and term sheet, including all exhibits, schedules or amendments thereto (or similar documents), with respect to such alternative financing.

Buyer shall keep Sellers reasonably informed as to the efforts made by Buyer or its Affiliates to obtain such rate base recovery and shall provide Sellers with copies of all filings, correspondence and other information to or from any Governmental Authority or other Person relating thereto; provided, however, that any Claim shall not expire until final resolution of any such rate base recovery proceeding, notwithstanding the terms of Section 11.2(a);

(j)If Sellers pay to Buyer any amount in respect of a claim for indemnity brought by Buyer pursuant to Section 11.1 and Buyer subsequently recovers, directly or indirectly (via a Project Company’s rate base recovery or otherwise), from any other Person any amount in respect of the Losses underlying such claim, then Buyer shall promptly pay to Sellers all such amounts recovered directly or indirectly from such other Person; provided that Buyer shall not be required to pay to Sellers any amount in excess of the amount paid by Sellers pursuant to Section 11.1 in respect of the subject claim;

(n)Sellers and Buyer acknowledge that after Closing the payment of money, as limited by the terms of this Agreement, shall be adequate compensation for breach of any representation, warranty, covenant or agreement contained in this Agreement or for any other Claim arising in connection with or with respect to the transactions contemplated in this Agreement. As the payment of money shall be adequate compensation, Buyer and each Seller hereby waives any right to rescind this Agreement or any of the transactions contemplated hereby; and

(o)references to Material Adverse Effect and other materiality qualifications shall be disregarded solely for purposes of calculating Losses with respect to which one Party indemnifies the other pursuant to Section 11.1(a). For the avoidance of doubt, such references shall not be disregarded in determining whether a breach by a Party of any of its representations made herein or hereunder has occurred.

11.3 Waiver of Claims. Subject to Section 11.1, effective as of Closing, Buyer hereby unconditionally waives and releases Sellers and their respective Affiliates and their respective Representatives and the Sellers Appointees (collectively, the “Released Parties”) from and against, all Claims and all obligations, damages and liabilities (whether absolute, accrued, contingent, fixed or otherwise, or whether due or to become due, whether known or unknown), expenses or other Losses arising from or relating to, and shall not (and shall not permit any Acquired Company to) make any Claim against the Released Parties in respect of, the Assumed Liabilities or any breach or alleged breach of any Charter Document or any fiduciary or similar duty relating to any actions or failures to act (including negligence or gross negligence) in connection with the business, ownership or operation of the Acquired Companies, whenever arising or occurring, and whether arising under Contract, statute, common law or otherwise. None of the Financing Sources will have any liability to the Company or any of its Affiliates relating to or arising out of this Agreement, the Financing or otherwise, whether at law, or equity, in contract, in tort or otherwise, and neither the Company nor any of its Affiliates will have any rights or claims against any of the Financing Sources hereunder or thereunder. In no event shall the Company be entitled to seek the remedy of specific performance of this Agreement against the Financing Sources.

11.4 Assumed Liabilities. Effective as of Closing, and subject to Section 11.1, Buyer hereby assumes the Assumed Liabilities.

11.5 Waiver of Other Representations.

(a)NOTWITHSTANDING ANYTHING IN THIS AGREEMENT TO THE CONTRARY, IT IS THE EXPLICIT INTENT OF EACH PARTY, AND THE PARTIES HEREBY AGREE, THAT NONE OF SELLERS NOR ANY OF THEIR RESPECTIVE AFFILIATES OR THEIR RESPECTIVE REPRESENTATIVES HAS MADE OR IS MAKING ANY REPRESENTATION OR WARRANTY WHATSOEVER, EXPRESS OR IMPLIED, WRITTEN OR ORAL, INCLUDING ANY IMPLIED REPRESENTATION OR WARRANTY AS TO THE CONDITION, MERCHANTABILITY, USAGE, SUITABILITY OR FITNESS FOR ANY PARTICULAR PURPOSE WITH RESPECT TO THE ACQUIRED INTERESTS, THE ACQUIRED COMPANIES OR ANY OF THEIR RESPECTIVE ASSETS, OR ANY PART THEREOF, EXCEPT FOR THOSE REPRESENTATIONS AND WARRANTIES EXPRESSLY MADE BY ANY SELLER IN ARTICLES III, IV AND V. IN PARTICULAR, AND WITHOUT IN ANY WAY LIMITING THE FOREGOING, (I) NONE OF SELLERS NOR ANY OF THEIR RESPECTIVE AFFILIATES OR THEIR RESPECTIVE REPRESENTATIVES MAKES ANY REPRESENTATION OR WARRANTY REGARDING ANY (X) TAX MATTERS EXCEPT AS EXPRESSLY MADE BY

SELLERS, AS APPLICABLE, IN SECTION 3.6 AND SECTION 5.9, (Y) ENVIRONMENTAL MATTERS EXCEPT AS EXPRESSLY MADE BY SELLERS IN SECTION 5.13 OR (Z) EMPLOYMENT MATTERS EXCEPT AS EXPRESSLY MADE BY SELLER IN SECTIONS 5.15 AND 5.16 AND (II) NONE OF SELLERS NOR ANY OF THEIR RESPECTIVE AFFILIATES OR THEIR RESPECTIVE REPRESENTATIVES MAKES ANY REPRESENTATION OR WARRANTY WITH RESPECT TO ANY FINANCIAL PROJECTIONS OR FORECASTS RELATING TO THE PROJECT COMPANIES OR THE PROJECT COMPANY ASSETS.

(b)EXCEPT FOR THOSE REPRESENTATIONS AND WARRANTIES EXPRESSLY MADE BY SELLERS IN ARTICLES III, IV AND V, SELLERS’ INTERESTS IN THE ACQUIRED INTERESTS ARE BEING TRANSFERRED HEREUNDER TO BUYER “AS IS, WHERE IS, WITH ALL FAULTS,” AND SELLERS AND THEIR RESPECTIVE AFFILIATES AND THEIR RESPECTIVE REPRESENTATIVES EXPRESSLY DISCLAIM ALL REPRESENTATIONS OR WARRANTIES OF ANY KIND OR NATURE, EXPRESS OR IMPLIED, AS TO THE CONDITION, VALUE OR QUALITY OF THE ACQUIRED COMPANIES OR THEIR RESPECTIVE ASSETS OR THE PROSPECTS (FINANCIAL OR OTHERWISE), RISKS AND OTHER INCIDENTS OF THE PROJECT COMPANIES OR THE PROJECT COMPANY ASSETS.

(c)BUYER ACKNOWLEDGES THAT THE REPRESENTATIONS AND WARRANTIES SET FORTH IN ARTICLES III, IV AND V AND IN ANY CERTIFICATES OF SELLERS ARE THOSE ONLY OF SELLERS AND NOT OF ANY OTHER PERSON, INCLUDING ANY AFFILIATE (INCLUDING ANY ACQUIRED COMPANY) OR REPRESENTATIVE OF SELLERS OR ANY OF THEIR RESPECTIVE AFFILIATES.

11.6 Waiver of Remedies.

(a)The Parties hereby agree that no Party shall have any liability, and no Party shall (and each Party shall cause its respective Affiliates not to) make any Claim, for any Loss or any other matter, under, relating to or arising out of this Agreement (including breach of representation, warranty, covenant or agreement) or any other document, agreement, certificate or other instrument delivered pursuant hereto, whether based on contract, tort, strict liability, other Laws or otherwise, except as expressly provided in Sections 7.2(b), 10.2, 11.1, 11.3, 11.4 and 12.14.

(b)NOTWITHSTANDING ANYTHING IN THIS AGREEMENT TO THE CONTRARY, NO PARTY NOR ANY OF ITS AFFILIATES SHALL BE LIABLE TO THE OTHER PARTY OR ITS AFFILIATES FOR SPECIAL, PUNITIVE, EXEMPLARY, INCIDENTAL, CONSEQUENTIAL OR INDIRECT DAMAGES, OR LOST PROFITS, WHETHER BASED ON CONTRACT, TORT, STRICT LIABILITY, OTHER LAW OR OTHERWISE AND WHETHER OR NOT ARISING FROM THE OTHER PARTY’S OR ANY OF ITS AFFILIATES’ SOLE, JOINT OR CONCURRENT NEGLIGENCE, STRICT LIABILITY OR OTHER FAULT (“Non-reimbursable Damages”); PROVIDED, HOWEVER, IN NO EVENT SHALL THIS SECTION 11.6(b) BE A LIMITATION ON ANY OBLIGATION OF A PARTY HEREUNDER WITH RESPECT TO A THIRD PARTY CLAIM RELATING TO SUCH OBLIGATION.

(c)Notwithstanding anything in this Agreement to the contrary, (i) no Representative or Affiliate of any Seller (nor any Representative of any such Affiliate or any Person directly or indirectly owning any interest in any Seller) shall have any liability to Buyer or any other Person as a result of the breach of any representation, warranty, covenant, agreement or obligation of any Seller in this Agreement or in any certificate delivered pursuant to this Agreement, and (ii) no Representative or Affiliate of Buyer (nor any Representative of any such Affiliate or any Person directly or indirectly owning any interest in Buyer) shall have any liability to Sellers or any other Person as a result of the breach of any representation, warranty, covenant or agreement of Buyer in this Agreement or in any certificate delivered pursuant to this Agreement.

11.7 Procedure with Respect to Third-Party Claims.

(a)If any Party becomes subject to a pending or threatened Claim of a third party and such Party (the “Claiming Party”) believes it has a claim against the other Party (the “Responding Party”) as a result, then the Claiming Party shall promptly notify the Responding Party in writing of the basis for such Claim setting forth the nature of the Claim and the amount thereof in reasonable detail. The failure of the Claiming Party to so notify the Responding Party shall not relieve the Responding Party of liability hereunder except to the extent that the defense of such Claim is prejudiced by the failure to give such notice.

(b)If any Proceeding is brought by a third party against a Claiming Party and the Claiming Party gives notice to the Responding Party pursuant to Section 11.7(a), the Responding Party shall be entitled to participate in such Proceeding and, if the Responding Party wishes, the Responding Party may elect to control the defense of such Proceeding (such election to be without prejudice to the right of the Responding Party to dispute whether such claim is for indemnifiable Losses under this Article XI), if (i) the Responding Party provides written notice to the Claiming Party that the Responding Party intends to undertake such defense and (ii) the Responding Party conducts the defense of the third-party Claim actively and diligently with counsel reasonably satisfactory to the Claiming Party. The Claiming Party shall, in its sole discretion, have the right to employ separate counsel (who may be selected by the Claiming Party in its sole discretion) in any such action and to participate in (but not control) the defense or settlement thereof, and the fees and expenses of such counsel shall be paid by such Claiming Party. The Claiming Party shall fully cooperate with the Responding Party and its counsel in the defense or compromise of such Claim. If the Responding Party assumes the defense of a Proceeding, no compromise or settlement of such Claim may be effected by the Responding Party without the Claiming Party’s consent unless (A) there is no finding or admission of any violation of Law or any violation of the rights of any Person and no effect on any other Claims that may be made against the Claiming Party and (B) the sole relief provided is monetary damages that are fully covered by the Responding Party.

(c)If notice is given to the Responding Party of the commencement of any third-party legal Proceeding and the Responding Party does not, within 30 days after the Claiming Party’s notice is given pursuant to Section 11.7(a), give notice to the Claiming Party of its election to control the defense of such legal Proceeding, or if any of the conditions set forth in clauses (i) and (ii) of Section 11.7(b) become unsatisfied, then the Claiming Party shall (upon notice to the Responding Party) have the right to control the defense, compromise or settlement of such claim; provided, however, that the Responding Party shall, subject to the limitations of liability set forth herein, reimburse the Claiming Party for the costs of defending against such third-party claim (including reasonable attorneys’ fees and expenses) and shall, subject to the limitations of liability set forth herein, remain otherwise responsible for any liability with respect to amounts arising from or related to such third-party claim, in both cases to the extent it is ultimately determined that such Responding Party is liable with respect to such third-party claim for a breach under this Agreement; provided, further, that the Claiming Party may not effect any such compromise or settlement without the consent of the Responding Party (which consent shall not be unreasonably withheld, denied or delayed). The Responding Party may elect to participate in such legal Proceedings, negotiations or defense at any time at its own expense.

(d)In the event a Claiming Party recovers Losses in respect of a claim for indemnification under this Article XI, no other Claiming Party shall be entitled to recover the same Losses in respect of a claim for indemnification hereunder.

11.8 Procedure with Respect to Direct Claims. Promptly after any Claiming Party comes to believe that it has a claim for indemnification against a Responding Party which does not involve a third-party Claim (a “Direct Claim”), the Claiming Party shall notify the Responding Party in writing of such Direct Claim and specify in such notice the basis for such Direct Claim setting forth the nature of the Claim and the amount thereof in reasonable detail. The Claiming Party shall enclose with such notice a copy of all material documents in the possession or under the control of such Claiming Party relating to such Direct Claim. Any failure of a Claiming Party to so notify a Responding Party shall not relieve the Responding Party of liability hereunder except to the extent that the defense of such Direct Claim is prejudiced by the failure to give such notice. The Claiming Party shall fully cooperate with the Responding Party and its counsel in determining the validity of any Direct Claim and in otherwise resolving such Direct Claim.

11.9 Access to Information.

(a)After the Closing Date, Sellers and Buyer shall grant each other (or their respective designees), and Buyer shall cause the Acquired Companies to grant to Sellers (or their respective designees), access at all reasonable times to all of the Records relating to the Acquired Companies in its possession or the possession of the Acquired Companies, and shall afford each such Person the right (at such Person’s expense) to take extracts therefrom and to make copies thereof, to the extent reasonably necessary to implement the provisions of, or to investigate or defend any claims among the Parties and/or their Affiliates arising under, this Agreement, subject to the reasonable confidentiality restrictions of the disclosing party. Without limiting the foregoing, Buyer shall, and shall cause the Acquired Companies to, grant to Sellers (and their respective designees) each of the foregoing access rights to the extent such Records are necessary or useful to Sellers in connection with any investigation or audit by a Governmental Authority or any claim or dispute by or with any Person other than Buyer or the Project Companies. Buyer shall maintain, and shall cause the Acquired Companies to maintain, such Records until the seventh anniversary of the Closing Date (or for such longer period of time as Sellers shall advise Buyer is necessary in order to have Records available with respect to Tax matters), or if any of the Records pertain to any claim or dispute pending on the seventh anniversary of the Closing Date, Buyer shall maintain any of the Records designated by Sellers or their respective Representatives until such claim or dispute is finally resolved and the time for all appeals has been exhausted. Notwithstanding anything herein to the contrary, in the event of a dispute between the Parties, the furnishing of, or access to, the Records shall be subject to applicable rules relating to discovery.

(b)Sellers and Sellers’ respective Affiliates may retain a copy of all data room materials and all books and records prepared in connection with the transaction contemplated by this Agreement, including (i) copies of any books and records which may be relevant in connection with the defense of disputes arising hereunder and (ii) copies of all financial information and all other accounting books and records prepared or used in connection with the preparation of financial statements of Sellers. Without limiting the foregoing, ASC may retain a copy of all books and records related to the Retained ASC Interest.

(c)Notice provide by any Seller in accordance with this Agreement shall be deemed to have been given by all Sellers under this Agreement.

12.2 Entire Agreement. Except for the Confidentiality Agreement, this Agreement supersedes all prior discussions and agreements between the Parties and/or their Affiliates with respect to the subject matter hereof and contains the sole and entire agreement between the Parties and their Affiliates with respect to the subject matter hereof.

12.3 Expenses. Except as otherwise expressly provided in this Agreement, whether or not the transactions contemplated hereby are consummated, each Party will pay its own costs and expenses incurred in anticipation of, relating to and in connection with the negotiation and execution of this Agreement and the transactions contemplated hereby.

12.4 Disclosure. Unless the context otherwise requires, all capitalized terms used in the Schedules shall have the respective meanings assigned to such terms in this Agreement. Neither the Schedules, the exhibits nor any disclosure made in or by virtue of them constitutes or implies any representation, warranty, or covenant by Sellers not expressly set out in the Agreement, and neither the Schedules, the exhibits, nor any such disclosure has the effect of, or may be construed as, adding to, broadening, deleting from or revising the scope of any of the representations, warranties, or covenants of Sellers in the Agreement. Any item or matter disclosed or listed on any particular Schedule or exhibit is deemed to be disclosed or listed on any other Schedule to the extent it is reasonably apparent that such item relates or is applicable to, or is properly disclosed under, such other Schedule or the section of this Agreement to which such other Schedule corresponds, notwithstanding the fact that the Schedules are arranged to correspond to the sections of the Agreement, that a particular section of this Agreement makes reference to a particular Schedule, or that a particular representation, warranty or covenant in this Agreement may not make reference to a Schedule. Matters reflected in the Schedules are not necessarily limited to matters required by the Agreement to be reflected in the Schedules. The fact that any item of information is contained in the Schedules is not an admission of liability under any applicable Law, and does not mean that such information is required to be disclosed in or by the Agreement, or that such information is material, but rather is intended only to qualify the representations, warranties and covenants in the Agreement and to set forth other information required by the Agreement. Neither the specification of any dollar amount in any representation, warranty or covenant contained in this Agreement nor the inclusion of any specific item in the Schedules is intended to imply that such amount, or a higher or lower amount, or the item so included, or any other item, is or is not material, and no Party shall use the specification of any such amount or the inclusion of any such item in any dispute or controversy between or among the Parties as to whether any obligation, item or matter not described herein or included in the Schedules is or is not material for purposes of this Agreement. The information set forth on the Schedules or exhibits shall not be used as a basis for interpreting the terms “material”, “materially”, “materiality”, “Material Adverse Effect”, or any similar qualification in this Agreement. Neither the specification of any item or matter in any representation, warranty or covenant contained in this Agreement nor the inclusion of any specific item in the Schedules is intended to imply that such item or matter, or another item or matter, is or is not in the ordinary course of business, and no Party shall use the specification or the inclusion of any such item or matter in any dispute or controversy between or among the Parties as to whether any obligation, item or matter described or not described herein or included or not included in the Schedules is or is not in the ordinary course of business for purposes of the Agreement. Headings have been inserted in the Schedules for reference only and do not amend the descriptions of the disclosed items set forth in the Agreement.

12.5 Waiver. Any term or condition of this Agreement may be waived at any time by the Party that is entitled to the benefit thereof, but no such waiver shall be effective unless set forth in a written instrument duly executed by or on behalf of the Party waiving such term or condition. No waiver by any Party of any term or condition of this Agreement, in any one or more instances, shall be deemed to be or construed as a waiver of the same or any other term or condition of this Agreement on any future occasion. All remedies, either under this Agreement or by Law, will, subject to Section 11.6, be cumulative and not alternative.

12.6 Amendment. This Agreement may be amended, supplemented or modified only by a written instrument duly executed by Sellers and Buyer; provided, however, that notwithstanding the foregoing, in the event that any party seeks an amendment, modification, consent or waiver to any of Sections 11.3, 12.7 or 12.12 or this Section 12.6 that is adverse to the Financing Sources, the prior written consent of the Financing Sources shall be required before any such amendment, modification, consent or waiver may become effective.

12.7 No Third Party Beneficiary. Except for the provisions of Sections 7.2(b), 7.6, the last sentence of Section 7.17, 11.3, 11.5, 11.6, 12.6 and 12.12 (which are intended to be for the benefit of the Persons identified therein, including but not limited to the Financing Sources), the terms and provisions of this Agreement are intended solely for the benefit of the Parties and their respective successors or permitted assigns, and it is not the intention of the Parties to confer third-party beneficiary rights upon any other Person.

12.8 Assignment; Binding Effect. Any Party may assign its rights and obligations hereunder to an Affiliate but such assignment shall not release such Party from its obligations hereunder. Except as provided in the preceding sentence, neither this Agreement nor any right, interest or obligation hereunder may be assigned by any Party without the prior written consent of the other Party, and any attempt to do so will be void, except for assignments and transfers by operation of Law. Notwithstanding the foregoing, without the prior written consent of any other Person, Buyer, may at any time, in its sole discretion, assign, in whole or in part, (x) its rights and obligations pursuant to this Agreement to one or more of its Affiliates and (y) its rights under this Agreement for collateral security purposes to any lender providing financing to Buyer or its Affiliates and any such lender may exercise all of the rights and remedies of Buyer hereunder; provided that any such assignment shall not relieve Buyer of its obligations hereunder. Subject to this Section 12.8, this Agreement is binding upon, inures to the benefit of and is enforceable by the Parties and their respective successors and permitted assigns.

12.9 Headings. The headings used in this Agreement have been inserted for convenience of reference only and do not modify, define or limit any of the terms or provisions hereof.

12.10 Invalid Provisions. Upon any determination that any term or other provision of this Agreement is invalid, illegal or incapable of being enforced under any applicable rule of Law or public policy, the Parties shall negotiate in good faith to modify this Agreement so as to effect the original intent of the Parties as closely as possible in an acceptable manner to the end that the transactions contemplated hereby are fulfilled to the extent possible.

12.11 Counterparts; Facsimile. This Agreement may be executed in any number of counterparts, each of which will be deemed an original, but all of which together will constitute one and the same instrument. Any facsimile or .pdf copies hereof or signature hereon shall, for all purposes, be deemed originals.

12.12 Governing Law; Venue; and Jurisdiction.

(a)This Agreement shall be governed by and construed in accordance with the Laws of the State of New York (without regard to the conflict of laws principles thereof other than Section 5-1401 of the New York General Obligations Law). Each of the Parties irrevocably agrees that any legal action or proceeding (i) with respect to this Agreement or the transactions contemplated hereby or (ii) involving the Financing Sources arising out of, or relating to, the transactions contemplated hereby, the Financing or the performance of services thereunder or related thereto (any such legal action or proceeding described in this clause (ii), a “Financing Sources Action”) shall in each case be brought and determined in any state or federal court in New York County, State of New York, and

each of the Parties irrevocably submits to the exclusive jurisdiction of such courts solely in respect of (x) any legal proceeding arising out of or related to this Agreement and (y) any Financing Sources Action, and the Parties hereto further agree to waive and hereby waive, to the fullest extent permitted by law, any objection which any of them may now or hereafter have to the laying of venue of, and the defense of an inconvenient forum to the maintenance of, any Financing Sources Action in any such court. The Parties further agree that the Parties shall not bring suit with respect to any disputes arising out of this Agreement or the transactions contemplated hereby (including but not limited to any Financing Sources Action) in any court or jurisdiction other than the above specified courts; provided, however, that except in the case of a Financing Sources Action, the foregoing shall not limit the rights of the Parties to obtain execution of judgment in any other jurisdiction. The Parties further agree, to the extent permitted by Law, that a final and nonappealable judgment against a Party in any action or proceeding contemplated above shall be conclusive and may be enforced in any other jurisdiction within or outside the United States by suit on the judgment, a certified copy of which shall be conclusive evidence of the fact and amount of such judgment. The Parties agree that any Financing Sources Action shall be governed by, and construed in accordance with, the laws of the State of New York, without regard to the conflicts of law rules of such State that would result in the application of the laws of any other State.

(b)EACH PARTY HEREBY IRREVOCABLY AND UNCONDITIONALLY WAIVES TO THE FULLEST EXTENT PERMITTED BY LAW TRIAL BY JURY IN ANY LEGAL ACTION OR PROCEEDING RELATING TO THIS AGREEMENT (INCLUDING BUT NOT LIMITED TO ANY FINANCING SOURCES ACTION) AND WITH RESPECT TO ANY COUNTERCLAIM RELATED THERETO.

12.13 Attorneys’ Fees. If any Party shall bring an action to enforce the provisions of this Agreement, the prevailing Party or Parties shall be entitled to recover its reasonable attorneys’ fees and expenses incurred in such action from the unsuccessful Party or Parties.

12.14 Specific Performance. Each Party hereby acknowledges and agrees that the rights of each Party to consummate the transactions contemplated hereby (including the satisfaction of any condition to Closing) are special, unique and of extraordinary character and that, if, prior to the earlier of valid termination and Closing, any Party violates or fails or refuses to perform any covenant or agreement made by it herein, the non-breaching Party may be without an adequate remedy at law. If, prior to the earlier of valid termination and Closing, any Party violates or fails or refuses to perform any covenant or agreement made by such Party herein, any non-breaching Party may (at any time prior to the valid termination of this Agreement pursuant to Article X), subject to the terms hereof, institute and prosecute an action in any court of competent jurisdiction to enforce specific performance of such covenant or agreement or seek any other equitable relief. For purposes of clarification, nothing contained in this Agreement shall prevent or impair the ability of a Party to seek specific performance prior to the earlier of valid termination of this Agreement in accordance with Article X and Closing.

12.15 Waiver. Buyer agrees, on its own behalf and on behalf of its Affiliates and Representatives (including the Acquired Companies following Closing), that, following Closing, Bracewell & ▇▇▇▇▇▇▇▇ LLP may serve as counsel to Sellers and their Affiliates in connection with any matters related to this Agreement and the transactions contemplated by this Agreement, including any dispute arising out of or relating to this Agreement and the transactions contemplated by this Agreement, notwithstanding any representation by Bracewell & ▇▇▇▇▇▇▇▇ LLP of the Acquired Companies prior to the Closing Date. Buyer, on behalf of itself and its Affiliates and Representatives (including the Acquired Companies after Closing) hereby (a) consents to Bracewell & ▇▇▇▇▇▇▇▇ LLP’s representation of Sellers and Sellers’ Affiliates in connection with any matters related to this Agreement and the transactions contemplated by this Agreement, (b) waives any Claim it has or may have that Bracewell & ▇▇▇▇▇▇▇▇ LLP has a conflict of interest or is otherwise prohibited from engaging in such representation based on its representation of the Acquired Companies prior to Closing and (c) agrees that, in the event that a dispute arises between Buyer and/or any of the Acquired Companies or any of Buyer’s or the Acquired Companies’ respective Affiliates, on the one hand, and Sellers and/or Sellers’ Affiliates, on the other hand, Bracewell & ▇▇▇▇▇▇▇▇ LLP may represent Sellers and/or Sellers’ Affiliates in such dispute even though the interests of Sellers and Sellers’ Affiliates may be directly adverse to Buyer or the Acquired Companies or any of Buyer’s or the Acquired Companies’ respective Affiliates and even though Bracewell & ▇▇▇▇▇▇▇▇ LLP may have represented the Acquired Companies in a matter substantially related to such dispute. Buyer further agrees that, as to all communications among Bracewell & ▇▇▇▇▇▇▇▇ LLP, the Acquired Companies, Sellers or their respective Affiliates and Representatives prior to Closing that relate solely to this Agreement or the transactions contemplated by this Agreement, the attorney-client privilege belongs, to the extent such privilege exists, to Sellers and their Non-Company Affiliates and may be controlled by Sellers and their Non-Company Affiliates and will not, with respect to such privileged communications, pass to or be claimed by Buyer or the Acquired Companies or any of Buyer’s or the Acquired Companies’ respective Affiliates. To the extent that Buyer, the Acquired Companies, or any of Buyer’s or the Acquired Companies’ respective Affiliates has or maintains any ownership of the privilege with respect to these communications, Buyer agrees (on behalf of itself and all such Persons), except as may be required by applicable Law, not to waive or to attempt to waive the privilege without the express written approval of Sellers. Notwithstanding the foregoing, in the event that a dispute arises between Buyer or the Acquired Companies, on the one hand, and any other Person (other than Sellers and their Non-Company Affiliates), on the other hand, after Closing, the Acquired Companies may assert the attorney-client privilege against such Person to prevent disclosure of confidential communications by or with Bracewell & ▇▇▇▇▇▇▇▇ LLP.

12.16 Parent Guaranty. Each Party acknowledges that, on the date of this Agreement, Black Hills Corporation, a South Dakota corporation and Affiliate of Buyer, is executing and delivering to Sellers the Guaranty (the “Guaranty”) that is attached hereto as Exhibit D.
