WHEREAS, contemporaneously with the Closing, the Company, AEP Holdco and Investor will enter into the Operating Agreement (as defined below) to memorialize their mutual agreements and understandings relating to the ownership, management and operation of the Company;

NOW, THEREFORE, in consideration of the representations, warranties, covenants and agreements contained in this Agreement and other good and valuable consideration, the receipt and sufficiency of which are hereby acknowledged, and intending to be legally bound hereby, the Parties hereby agree as follows:

ARTICLE I

CONTRIBUTION; PURCHASE PRICE; THE CLOSING

Section 1.1Contribution and Unit Issuance. Upon the terms and subject to the conditions set forth in this Agreement, at the Closing, (a) Investor shall contribute to the

Company the Purchase Price, and (b) the Company shall issue to Investor, the Purchased Interests, free and clear of all Liens other than (i) those created pursuant to Contracts (including the Operating Agreement) to which Investor or any of its Affiliates is a party and (ii) those that may be deemed to exist pursuant to securities Laws of general applicability.

Section 1.2Purchase Price.

(a)The aggregate purchase price to be paid by Investor for the Purchased Interests is an amount equal to (i) $2,820,000,000 (the “Base Purchase Price”), plus (ii) the Capital Contribution Amount, minus (iii) the Distribution Amount (the resulting amount, the “Purchase Price”).

(b)Not later than five (5) Business Days prior to the Closing Date, the Company shall provide Investor with a written statement (the “Statement”) reflecting the estimated calculation of the Purchase Price (the “Estimated Purchase Price”) by reference to the total Capital Contribution Amount, the total Distribution Amount, the amount of Excess Distributions (if any) and the amount of Offset Contributions (if any) based upon the accounting books and records of the Company and its Subsidiaries and in accordance with GAAP and FERC Accounting Requirements, as applicable (the “Accounting Principles”).

(c)Post-Closing Purchase Price Adjustment

(i)Preparation of Closing Statement. Within sixty (60) days after the Closing Date, AEP Holdco shall prepare, or cause to be prepared, and deliver to the Investor a statement (the “Post-Closing Statement”) setting forth, in reasonable detail and together with reasonable supporting information, AEP Holdco’s calculation of the actual amount of: (A) the total Capital Contribution Amount, if any, (B) Distribution Amount, if any, (C) the amount of any Excess Distributions, if any, (D) the amount of Offset Contributions (if any), and, using the foregoing components, a calculation of the estimated Final Purchase Price. The Post-Closing Statement must set forth a reconciliation between the estimated calculations set forth on the Statement and those calculations set forth on the Post-Closing Statement.

(ii)Dispute. Within thirty (30) days following receipt by the Investor of the Post-Closing Statement, the Investor shall deliver written notice to AEP Holdco of any dispute the Investor has with respect to the preparation or content of the Post-Closing Statement (the “Dispute Notice”). Any Dispute Notice shall contain a reasonably detailed description of the Investor’s position with respect to each such disputed item. If the Investor does not notify AEP Holdco of a dispute by delivering a Dispute Notice with respect to the Post-Closing Statement within such thirty (30)-day period, such Post-Closing Statement will be final, conclusive and binding on the Parties and such Post-Closing Statement shall become the “Final Closing Statement”. In the event of such notification of a dispute, the Investor shall provide AEP Holdco reasonable supporting documents and calculations, including reasonable detail with its delivery of a Dispute Notice, and the Investor and AEP Holdco shall negotiate in good faith to attempt to resolve such dispute. If the Investor and AEP Holdco, notwithstanding such good faith effort, fail to resolve such dispute within thirty (30) days following receipt by AEP Holdco of the Dispute Notice, then, upon the election of either Party by written notice to the other Party, the Investor and AEP Holdco shall jointly engage one of the “Big Four” accounting firms to be mutually selected (or, if such firm is unable to be engaged, another nationally recognized firm of independent accountants mutually agreeable to the Investor and AEP Holdco) (the “Independent Accountants”) to resolve such dispute. The Independent Accountants shall review only those items contained in the Dispute Notice that remain in dispute between AEP Holdco and the Investor. In connection with the

engagement of the Independent Accountants, AEP Holdco and the Investor will execute such engagement, indemnity and other agreements as the Independent Accountants may reasonably require as a condition to such engagement. As promptly as practicable, but in any event within thirty (30) days after the selection of the Independent Accountants and execution of such engagement, indemnity or other agreements and based solely on (i) a written submission provided by each of the Investor and AEP Holdco to the Independent Accountants within ten (10) days following the Independent Accountants’ selection (and without independent investigation on the part of the Independent Accountants) and (ii) the terms and provisions of this Agreement, the Independent Accountants will determine whether the Post-Closing Statement requires adjustment in accordance with the terms of this Agreement. Once appointed, the Independent Accountants shall have no ex parte communications with any of the Parties concerning dispute. All communications between AEP Holdco or the Investor, on the one hand, and the Independent Accountants, on the other hand, shall be conducted in writing, with copies sent simultaneously to AEP Holdco and the Investor, as applicable, or at a meeting (whether in-person or by electronic communications) involving both AEP Holdco and the Investor where AEP Holdco and the Investor have been provided advance notice. In resolving any disputed item, the Independent Accountants may not assign a value to any item in dispute (A) greater than the greatest value claimed for such item in AEP Holdco’s proposed value for such disputed item as set forth in the Statement or the Post-Closing Statement, as applicable, or the Investor’s proposed value for such disputed item as set forth in the Dispute Notice, or (B) lower than the least value claimed for such item in AEP Holdco’s proposed value for such disputed item as set forth in the Statement or the Post-Closing Statement, as applicable, or the Investor’s proposed value for such disputed item as set forth in the Dispute Notice. The Independent Accountants shall (x) act as an expert and not as an arbitrator and (y) consider only those items and amounts in the Investor’s and AEP Holdco’s respective calculations in the Post-Closing Statement or the Investor’s proposed value for such disputed item as set forth in the Dispute Notice, including each of the components thereof, that are in the Dispute Notice and identified as being items and amounts to which the Investor and AEP Holdco have been unable to agree. AEP Holdco and the Investor will each bear its own legal fees and other costs of presenting its case to the Independent Accountants. The Post-Closing Statement, to the extent finally determined by the Independent Accountants and reflecting any non-disputed item, shall become the “Final Closing Statement”. Upon resolution of the items in the Dispute Notice by the Independent Accountants, the fees and expenses of the Independent Accountants will be borne by AEP Holdco and the Investor proportionately based on the relative success of each of them in resolving the items in the Dispute Notice, as determined by the Independent Accountants (i.e., so that the more successful Party bears a lesser proportion of such fees and expenses), and AEP Holdco and the Investor shall make any necessary true-up payments between themselves to accomplish the foregoing with respect to any fees and expenses advanced to the Independent Accountants prior to such resolution. Notwithstanding anything to the contrary, in no event shall any costs or expenses of any Party under this Section 1.2(c) (including the preparation of the Post-Closing Statement and any expenses allocated to any Party in engaging the Independent Accountant) be borne by the Company or its Subsidiaries.

(iii)Adjustment Mechanisms. Upon the determination of the Final Closing Statement, the Purchase Price shall be adjusted as follows: (A) if the Final Purchase Price is less than the Estimated Purchase Price (the amount of such shortfall, the “Purchase Price Shortfall Amount”), AEP Holdco shall contribute to the Company an amount of cash equal to (I) the Purchase Price Shortfall Amount divided by (II) the Percentage Interest of the Investor as of such time, to an account designated in writing by the Company or (B) if the Final Purchase Price is greater than or equal to the Estimated Purchase Price (the amount of such excess, the “Purchase Price Excess Amount”), the

Investor shall contribute to the Company an amount of cash equal to (I) the Purchase Price Excess Amount, divided by (II) the Percentage Interest of AEP Holdco as of such time, to an account designated in writing by the Company.

(iv)Final Payment. The Parties agree that upon the payment of the Estimated Purchase Price at Closing and amounts provided in this Section 1.2 by the applicable Party following Closing, the Investor shall have no further obligation to pay the Company any amounts in connection with the acquisition of the Purchased Interests.

(v)Timing and Treatment of Payments. Any payment due under this Section 1.2 shall be made within the later of (A) ten (10) Business Days of the date on which the Final Closing Statement is finally determined pursuant to this Section 1.2, and (B) two (2) Business Days following the identification by the Company of the account to which funds will be delivered. Any contribution to the Company made pursuant to this Section 1.2(c) shall be treated as an adjustment to the Purchase Price in an amount equal to the Purchase Price Shortfall Amount or the Purchase Price Excess Amount, as applicable, for all purposes unless otherwise required by applicable Law and shall not result in an adjustment following the Closing to the equity ownership interest percentages of the members of the Company.

Section 1.3Closing. The closing of the transactions contemplated hereby (the “Closing”) shall take place at the offices of ▇▇▇▇▇▇ ▇▇▇▇▇, ▇▇▇ ▇▇▇▇ ▇▇▇▇▇▇, ▇▇▇ ▇▇▇▇, ▇▇ ▇▇▇▇▇ (or remotely via the electronic exchange of executed documents) at 10:00 a.m., Eastern Time, on the tenth (10th) Business Day immediately following the date of the satisfaction or waiver (by the Party entitled to the benefit thereof, to the extent permitted by applicable Law) of the conditions set forth in Article VI (other than those conditions that by their terms or nature are to be first satisfied at the Closing, but subject to the satisfaction or waiver of those conditions at such time), or on or at such other date, time or place as is agreed to in writing by the Parties. The date on which the Closing occurs is referred to herein as the “Closing Date.” The Closing shall be deemed to occur at 12:01 a.m., Eastern Time, on the Closing Date.

(a)Delivery of Equity Commitment. Concurrently with the execution of this Agreement, Investor has delivered to AEP Holdco and the Company true, correct and complete copies of executed equity commitment letters addressed to Investor, dated as of the Effective Date (including all exhibits, schedules and annexes thereto, as amended, replaced, waived, supplemented or modified in accordance with Section 5.5(b), the “Equity Commitment Letters”), pursuant to which each of the Guarantors have committed, subject to the terms and conditions set forth therein, to provide equity financing in an amount set forth therein for the purpose of funding a portion of the Financing Uses (the “Equity Financing”).

(b)Status of Financing Commitments. As of the Effective Date:

(i)each of the Equity Commitment Letters is in full force and effect and represents a valid and binding obligation of Investor and, to the Knowledge of Investor, the other parties thereto, enforceable by and against such parties in accordance with their terms, subject to the Bankruptcy and Equity Exception;

(ii) none of the commitments under the Equity Commitment Letters have been withdrawn, rescinded, replaced or terminated or otherwise amended or modified in any respect;

(iii)no event has occurred that, with or without notice, lapse of time or both, would constitute a default or breach on the part of Investor or, to the Knowledge of Investor, any other party thereto under any term or condition of the Equity Commitment Letters that could affect the availability of the Equity Financing on the Closing Date;

(iv)the Investor has fully paid (or caused to be paid) and all fees and other amounts that are due and payable on or prior to the Effective Date in connection with the Equity Financing; and

(v)neither the Investor nor any of its Affiliates has entered into any agreement, side letter or other arrangement relating to the Equity Financing, other than as set forth in the Equity Commitment Letter that could affect the availability of the Equity Financing on the Closing Date.

As of the Effective Date, assuming the satisfaction of each of the conditions to Closing set forth in Article VI and the performance by AEP Holdco and the Company of their respective obligations under this Agreement, Investor has no reason to believe that any of the conditions to the Equity Financing in the Equity Commitment Letters will not be satisfied at the Closing or that the Equity Financing will not be made available to Investor at the Closing in order to consummate the transactions contemplated by this Agreement in accordance with this Agreement. As of the Effective Date, Investor is unaware of any fact or occurrence that would reasonably be expected to make any of the assumptions or any of the statements set forth in the Equity Commitment Letters inaccurate in any material respect or that would reasonably be expected to cause the Equity Commitment Letters to be ineffective.

(e)Financing Not a Condition. The Investor understands and acknowledges that its obligations under this Agreement are not in any way contingent upon or otherwise subject to or conditional upon the Investor’s consummation of any financing arrangements, the Investor’s obtaining of any financing or the availability, grant, provision or extension of any financing to the Investor.

(b)In furtherance and not in limitation of their obligations under this Agreement, the Parties shall, and shall cause their FERC Affiliates to, use their respective reasonable best efforts to promptly obtain any clearance, consent or Order of any Governmental Body that may be, or become, required in connection with the Regulatory Approvals or otherwise necessary for the consummation of this Agreement and the transactions contemplated hereby prior to the Outside Date, and to avoid the entry of, or effect the dissolution of, any permanent, preliminary or temporary Order that would otherwise have the effect of preventing or materially delaying the transactions contemplated hereby or that would cause the Closing not to occur prior to the Outside Date. In furtherance of the foregoing, Investor shall take, and not refrain from taking, any and all steps necessary to avoid or eliminate each and every impediment in connection with the Regulatory Approvals that may be asserted by any Governmental Body so as to enable the Parties to consummate the transactions contemplated hereby as expeditiously as practicable (and in any event prior to the Outside Date), including (i) with the consent of the Company, opposing (including through litigation on the merits) any motion or action for a temporary, preliminary or permanent injunction or Order against or preventing or delaying the consummation of the transactions contemplated hereby, (ii) promptly complying with any requests for additional information or documentation in respect of Investor or any of its FERC Affiliates (including promptly making available any such information and personnel that may be requested by a Governmental Body or that may be necessary or desirable, in the case of FERC, to prepare and file answers to any hostile motions or pleadings that may be filed with FERC), (iii) proposing, negotiating, committing to, entering into a consent decree, consent agreement or other agreement or arrangement containing Investor’s agreement to hold separate, license, sell or divest (pursuant to such terms as may be required by any Governmental Body) such assets or businesses of the Company, Investor and their respective FERC Affiliates and effecting such holding separate, license, sale or divestiture sufficiently prior to the Outside Date to permit the Closing to occur on the terms of this Agreement prior to the Outside Date, effective as of the Closing (including proposing, committing to, and/or entering into customary ancillary agreements relating to any such sale, divestiture, licensing or disposition of such assets or businesses), (iv) subject to Section 5.3(h), making amendments or modifications to this Agreement and the other transaction documents contemplated hereby to the extent required by a Governmental Body (it being understood no such amendments or modifications will be effective against any Party prior to the Closing) and (v) agreeing to such limitations on conduct or actions of members of Investor or the Company and its Subsidiaries effective as of the Closing, in each case, as may be required in order to obtain satisfaction of the closing conditions set forth in Section 6.1(a) prior to the

Outside Date; provided, however, that any action contemplated by clauses (iii) and (v) above is conditioned upon consummation of the transactions contemplated hereby.

(c)The Parties shall use their respective reasonable best efforts to (A) as promptly as practicable after the date hereof, jointly file with CFIUS a CFIUS Declaration, (B) in the event the Parties submit a CFIUS Declaration and CFIUS subsequently requests that the Parties file a written notice pursuant to 31 C.F.R. § 800.407(a)(1): (x) as promptly as practicable jointly file with CFIUS a draft CFIUS Notice and (y) as promptly as practicable after the resolution of all questions and comments received from CFIUS staff on the draft CFIUS Notice (or receipt of confirmation that the CFIUS staff have no such questions or comments) jointly file a formal CFIUS Notice pursuant to the DPA, and (C) provide any supplemental information and other related information requested by CFIUS pursuant to the DPA as soon as practicable (and, in any case, within the time periods required by CFIUS); provided, however, that any Party may request in good faith an extension of time pursuant to the DPA to respond to CFIUS requests for information.

(d)The Parties shall, and shall cause their respective Affiliates to, use their respective reasonable best efforts to (A) cooperate in all respects in connection with the CFIUS Declaration or CFIUS Notice, as applicable, including by allowing the other Parties to have a reasonable opportunity to review in advance and comment on drafts of filings and submissions, provided, that materials provided by a Party to the other Parties’ counsel may be redacted and/or subject to a confidentiality agreement (i) to remove and/or protect references concerning the valuation of the Company and its Subsidiaries and personal identifier information required to be submitted with a CFIUS Notice; and (ii) as necessary to comply with contractual arrangements or applicable Laws; and (iii) as necessary to address reasonable attorney-client privilege concerns, (B) to the extent not prohibited by CFIUS, promptly inform the other Parties of any substantive communication received from, or given by such Party to, CFIUS, including by promptly providing copies to the other Parties of any such substantive written communications and (C) permit the other Parties to review in advance any substantive communication that it gives to, and consult with each other in advance of any conference, meeting, or substantive telephone call with, CFIUS, and to the extent not prohibited by CFIUS, provide the other Parties the opportunity to attend and participate in any conference, meeting, or substantive telephone call with CFIUS. Each of the Parties shall use its respective reasonable best efforts to take or cause to be taken, all actions, and to do, or cause to be done, and to assist and cooperate with each other in doing, all things reasonably necessary, proper, or advisable to obtain CFIUS Clearance; provided, that nothing herein shall obligate Investor or its Affiliates to propose, negotiate commit to and effect by consent decree, hold separate Order or otherwise, regardless of the consideration, the sale, divestiture, license or disposition of any assets or businesses of Investor or its Affiliates to obtain CFIUS Clearance.

(e)The Parties shall instruct their respective counsel to cooperate with each other and use reasonable best efforts to facilitate and expedite the identification and resolution of any issues arising in connection with the Regulatory Approvals as promptly as practicable. Such reasonable best efforts and cooperation include counsel’s undertaking (i) to keep the other Party’s counsel appropriately and reasonably informed of material communications from and to personnel of the reviewing Governmental Bodies and (ii) to confer with the other Party’s counsel regarding appropriate material contacts with and response to personnel of such Governmental Bodies and the content of any such contacts or presentations, in each case in connection with the transactions contemplated by this Agreement and (iii) promptly and comprehensively advising the other Party of any facts, developments, or communications that may reasonably be expected to have a bearing on the availability and timing of any of the Regulatory Approvals. Unless prohibited by applicable Law or by the applicable Governmental Body, and to the extent reasonably practicable, no Party shall participate in any substantive meeting or discussion with any Governmental Body with respect of any such filings, applications, investigation or other

inquiry without giving the other Parties prior notice of the meeting or discussion and, to the extent permitted by the relevant Governmental Body, the opportunity to attend and participate in such meeting or discussion. In the event any Party or its Representatives are prohibited by applicable Law or by the applicable Governmental Body from participating in or attending any such meeting or engaging in any such discussion, such Party shall keep the other Parties reasonably and promptly apprised with respect thereto. To the extent reasonably practicable, each Party shall provide the other Parties with copies of all material correspondence, filings and communications between it and its Subsidiaries and FERC Affiliates and their respective Representatives, on the one hand, and any Governmental Body, on the other hand, with respect to this Agreement or the transactions contemplated hereby. Each Party will have the right to review (subject to appropriate redactions for confidentiality and attorney-client privilege concerns) and approve the content of any presentations, white papers, economic analysis or other written materials to be submitted by the other Party or Parties to any Governmental Body, with respect to this Agreement or the transactions contemplated hereby, in advance of any such submission. In exercising the foregoing rights, each Party shall act reasonably and as promptly as practicable. No Party shall withdraw its filing or extend the waiting period in connection with the Regulatory Approvals without the prior written consent of the other Parties.

(f)During the Interim Period, Investor shall not, and shall not permit any of its FERC Affiliates to, acquire or agree to acquire direct or indirect control (by merging or consolidating with, or by purchasing a material portion of the assets of or equity in, by representation through a non-independent director or manager on the board of directors or managers, as the case may be, or by any other manner), of any Person or portion thereof, or otherwise acquire or agree to acquire any assets, licenses, rights, operations or businesses of any Person, if the entering into a definitive agreement relating to, or the consummation of, such acquisition, merger or consolidation in the United States would be reasonably expected to impose any material delay that does, or would reasonably be expected to, result in not obtaining the Regulatory Approvals, in each case, prior to the Outside Date (as the same may be extended under Section 7.1(b)(i)), or increase in any material respect the risk of not obtaining, the Regulatory Approvals or increase in any material respect the risk of entry of a Restraint or any other Order prohibiting the consummation of the transactions contemplated hereby, in each case, prior to the Outside Date (as the same may be extended under Section 7.1(b)(i)).

(g)Each of the Parties further agrees that it shall, and shall cause its FERC Affiliates to, materially comply with any applicable post-Closing notification or requirements of any antitrust, trade competition, investment control reporting or similar Law of any Governmental Body with competent jurisdiction.

(h)Notwithstanding anything else to the contrary in this Agreement (including Section 5.4), in no event shall AEP Holdco or its FERC Affiliates be required to offer, accept, incur or agree, in connection with this Agreement or the transactions contemplated thereby, to any material undertaking, commitment, liability, obligation, or condition that would be adverse to AEP Holdco or the Company; provided that a requirement or condition imposed by FERC in its order under FPA Section 203 shall not be a “material undertaking, commitment, liability, obligation, or condition” for the purposes of this subsection if it (i) is regularly imposed by FERC in any order or orders under FPA Section 203 involving other changes of control over transmission-owning public utilities, (ii) does not itself set forth a requirement to reduce the FERC-jurisdictional rates of any of AEP Holdco’s FERC Affiliates, including the transmission rates of AEP I&M TransCo or AEP Ohio TransCo, (iii) imposes any requirement as to which, in substantial part, AEP Holdco or its FERC Affiliates are already complying with or to which AEP Holdco or its applicable affected FERC Affiliate is already subject, or (iv) was committed-to or offered by or on behalf of AEP I&M TransCo or AEP Ohio TransCo in the FPA Section 203 application.

Subject to, and not in limitation of, the other terms of this Agreement (including, for the avoidance of doubt, Section 5.3, which shall be the Parties sole obligation in respect of Regulatory Approvals), during the Interim Period, each of the Parties agrees to use its reasonable best efforts to take or cause to be taken all action, to do or cause to be done, and to assist and cooperate with the other Parties in doing, all things necessary, proper or advisable under applicable Laws and regulations to satisfy the conditions to the Closing set forth in Article VI and to consummate and make effective, in the most expeditious manner practicable, the transactions contemplated hereby, including (a) obtaining consents, waivers or approvals of any third parties necessary under applicable Law to consummate the transactions contemplated hereby, (b) defending any lawsuits or other legal proceedings, whether judicial or administrative, initiated by a third party challenging this Agreement or any matter contemplated hereby, and (c) executing and delivering such instruments, and taking such other actions, as any other Party may reasonably require in order to carry out the intent of this Agreement.

Section 5.5Company’s Obligations in Respect of Financing.

(a)The parties hereto acknowledge that Investor has arranged, or may attempt to arrange, third party debt financing for the purpose of funding the transactions contemplated by this Agreement (the “Debt Financing”) and, if Investor obtains, or so chooses to seek, the Debt Financing, subject to Section 5.5(b), prior to the Closing, AEP Holdco and the Company shall use their respective commercially reasonable efforts to provide to Investor such customary cooperation that is reasonably requested by Investor in connection with the Debt Financing or any permitted replacement, amended, modified or alternative financing (collectively with the Debt Financing, the “Available Financing”), the proceeds of which will be used to consummate the transactions contemplated hereby (provided, that such requests shall not unreasonably interfere with the ongoing operations of AEP Holdco and the Company and their respective Subsidiaries), including:

(i)participation by senior management of AEP Holdco and the Company in, and assistance with, the preparation of customary rating agency presentations and/or lender presentations and a reasonable number of meetings with each of the main rating agencies and/or the parties acting as lead arrangers, bookrunners or agents for, and prospective lenders of, the Available Financing, at times and locations to be mutually agreed and upon reasonable notice;

(ii)delivery to Investor of the Financing Information;

(iii)assisting in the preparation of schedules to the definitive loan documentation, as may be reasonably requested; and

(iv)no less than five (5) Business Days prior to the Closing Date, furnishing to Investor and the Financing Sources all documentation and information as is reasonably requested in writing by the Financing Sources, in each case, at least ten (10) Business Days prior to the Closing Date, about the Company and its Subsidiaries that the Financing Sources reasonably determine is required by United States regulatory authorities under applicable “know your customer” and anti-money laundering rules and regulations, including, without limitation, the PATRIOT Act, including, if the Company or any of its Subsidiaries qualifies as “legal entity customers” under 31 C.F.R. § 1010.230, a certification regarding beneficial ownership.

(b)Notwithstanding anything in Section 5.5(a) or this Agreement to the contrary, the cooperation requested by Investor pursuant to Section 5.5(a) shall not (i) unreasonably interfere with the ongoing operations of the Company and its Subsidiaries, or (ii) require any of AEP Holdco or any of its Subsidiaries to (A) pay any commitment or other similar fee, (B) have or incur any liability or obligation in connection with the Debt Financing, including under any agreement or any document related to the Debt Financing, (C) commit to taking any action (including entering into any Contract) whether or not contingent upon the Closing or to otherwise execute any document, agreement, certificate or instrument in connection with any Debt Financing, (D) take any action that would conflict with, violate or breach or result in a violation or breach of or default under any Organizational Documents of AEP Holdco or any of its Affiliates, any Contract, this Agreement or any other document contemplated hereby or any Law, (E) take any action that could subject any Representative of AEP Holdco or any of its Affiliates to any actual or potential personal liability, (F) provide access to or disclose information that the Company determines in good faith could jeopardize any attorney-client privilege of, or conflict with any confidentiality requirements applicable to, the Company or any of its Affiliates, (G) reimburse any expenses or provide any indemnities, (H) make any representation, warranty or certification, (I) adopt resolutions or otherwise approve agreements, documents or instruments in connection with the Debt Financing or (J) provide any cooperation or information that does not pertain to the Company or its Subsidiaries. In no event shall AEP Holdco or the Company be in breach of Section 5.5(a) because of its failure to deliver any financial or other information that is not currently readily prepared in the Ordinary Course of Business at the time requested by Investor or for the failure to obtain review of any financial or other information by its accountants. Investor shall promptly reimburse AEP Holdco or the Company (as applicable) for all reasonable and documented out-of-pocket cost and expenses incurred by AEP Holdco, the Company or any of their Subsidiaries in connection with the cooperation contemplated by Section 5.5(a), including (i) reasonable and documented attorneys’ fees and (ii) expenses of the Company’s accounting firms engaged to assistance in connection with the Debt Financing. Investor shall indemnify and hold harmless AEP Holdco, the Company and its Subsidiaries, and their respective Representatives, from and against any and all Losses suffered or incurred by them in connection with the arrangement of the Debt Financing and any information utilized in connection therewith (except to the extent such Losses result from such Person’s gross negligence or willful misconduct). In no event shall any failure on the part of AEP Holdco or the Company to comply with its obligations under Section 5.5(a) give rise to the failure of a condition set forth in Article VI or be grounds for termination of this Agreement under Article VII.

(c)For the avoidance of doubt, receipt of any third party financing (including any Debt Financing) is not a condition precedent to the Closing or to a grant of specific performance as contemplated by (and subject to) Section 10.12. Subject to the other terms and conditions of this Agreement (including Article VI), Investor hereby affirms its obligation to effect the Closing and other transactions contemplated by this Agreement regardless of whether Investor obtains any third party financing (including any Debt Financing).

(d)Any information provided pursuant to this Section 5.5 shall be subject to the Confidentiality Agreements.

Notwithstanding such representation or any continued representation of the Company or any of its Subsidiaries, Investor (on its own behalf and on behalf of its Affiliates) hereby consents thereto and waives any conflict of interest arising therefrom, and Investor shall cause its Affiliates to consent to waive any conflict of interest arising from such representation. Investor and AEP Holdco hereby agree that, in the event that a dispute arises after the Closing between Investor or its Affiliates, on the one hand, and any member of AEP Parent Group, on the other hand, ▇▇▇▇▇▇ ▇▇▇▇▇ may represent such member in such dispute even though the interests of such member may be directly adverse to Investor or its Affiliates, and even though ▇▇▇▇▇▇ ▇▇▇▇▇ may have represented, or may be handling ongoing matters for, Investor or its Affiliates. Investor agrees that (x) all communications among any member of the AEP Parent Group, the Company and its Subsidiaries, any of their respective Affiliates, directors, officers, employees or Advisors, on the one hand, and ▇▇▇▇▇▇ ▇▇▇▇▇, on the other hand, that relate in any way to the negotiation, preparation, execution, delivery and closing under, or any dispute arising in connection with, this Agreement, or otherwise relating to any potential sale of Equity Interests in the Company or the transactions contemplated hereby (the “Protected AEP Holdco Communications”) shall be deemed to be privileged and confidential communications, (y) all rights to such Protected AEP Holdco Communications, the expectation of client confidentiality, and the control of the confidentiality and privilege applicable thereto, belong to and shall be retained by the AEP Parent Group and (z) to the extent Investor or any of its Affiliates should discover in its possession after the Closing any Protected AEP Holdco Communications, it shall take reasonable steps to preserve the confidentiality thereof and promptly deliver the same to AEP Holdco, keeping no copies, and shall not by reason thereof assert any loss of confidentiality or privilege protection. As to any such Protected AEP Holdco Communications prior to the Closing Date, Investor, together with any of its respective Affiliates, Subsidiaries, successors or assigns, further agree that none of the foregoing may use or rely on any of the Protected AEP Holdco Communications in any action against or involving the AEP Parent Group or ▇▇▇▇▇▇ ▇▇▇▇▇ after the Closing. The Protected AEP Holdco Communications may be used by the AEP Parent Group in connection with any dispute that relates in any way to this Agreement or the transactions contemplated hereby.

Section 5.9R&W Insurance Policy. In the event that Investor or any of its Affiliates obtains a representations and warranties insurance policy in respect of the representations and warranties contained in this Agreement or in any certificate or other instrument contemplated by or delivered in connection with this Agreement (such policy, an “R&W Insurance Policy”) (a) all premiums, underwriting fees, brokers’ commissions and other costs and expenses related to such R&W Insurance Policy shall be borne solely by Investor or such Affiliate, (b) such R&W Insurance Policy shall not provide for any “seller retention” (as such phrase is commonly used in

the representations and warranties insurance policy industry), and (c) such R&W Insurance Policy shall expressly waive any claims of subrogation against any member of the AEP Parent Group or any of their respective Affiliates, except in the event of Fraud. At the request of Investor, AEP Holdco and the Company shall reasonably cooperate with Investor with respect to the underwriting of any such R&W Insurance Policy at the sole cost of Investor.

(d)by the Company, by written notice to Investor, if Investor shall have breached or failed to perform any of its representations, warranties, covenants or agreements set forth in this Agreement, which breach or failure to perform (i) would give rise to the failure of a condition set forth in Section 6.1 or Section 6.3, respectively, and (ii) cannot be cured such that the failure of the applicable condition set forth in Section 6.1 or Section 6.3 in respect thereof would be resolved or, if capable of being so cured, has not been so cured by the earlier of (A) 30 days following receipt of written notice from the Company stating its intention to terminate this Agreement pursuant to this Section 7.1(d) and the basis for such termination and (B) the Outside Date; provided, that the Company shall not have the right to terminate this Agreement pursuant to this Section 7.1(d) if the Company or AEP Holdco is then in material breach of any representation, warranty, covenant or other agreement hereunder;

(e)by the Company, by written notice to Investor, if (i) the conditions set forth in Section 6.1 and Section 6.2 (other than those conditions that by their nature are to be first satisfied at the Closing and which conditions would be satisfied or would be capable (assuming Investor has not breached the terms of this Agreement in a manner that would make such conditions incapable of being satisfied) of being satisfied if the Closing Date were the date on which such written notice is delivered) have been satisfied or waived by Investor, (ii) the Company delivers to Investor a written notice on or after the date that the Closing is required to occur pursuant to Section 1.3 that all conditions set forth in Section 6.3 have been satisfied (other than those conditions that by their nature are to be satisfied at the Closing and which conditions

would be satisfied or would be capable (assuming Investor has not breached the terms of this Agreement in a manner that would make such conditions incapable of being satisfied) of being satisfied if the Closing Date were the date on which such written notice is delivered) or that it is waiving any such unsatisfied conditions set forth in Section 6.1 and Section 6.3 and the Company and AEP Holdco are ready, willing and able to consummate the Closing and will consummate the Closing if Investor does, (iii) Investor fails to effect the Closing within two (2) Business Days after the delivery of such notice to Investor (or, if earlier, the Outside Date) and (iv) the Company and AEP Holdco stood ready, willing and able to consummate the Closing during such two (2) Business Day period; or

(f)by Investor, by written notice to AEP Holdco if (i) the conditions set forth in Section 6.1 and Section 6.3 (other than those conditions that by their nature are to be first satisfied at the Closing and which conditions would be satisfied or would be capable (assuming AEP Holdco or the Company has not breached the terms of this Agreement in a manner that would make such conditions incapable of being satisfied) of being satisfied if the Closing Date were the date on which such written notice is delivered) have been satisfied or waived by AEP Holdco, (ii) Investor delivers to AEP Holdco a written notice on or after the date that the Closing is required to occur pursuant to Section 1.3 that all conditions set forth in Section 6.2 have been satisfied (other than those conditions that by their nature are to be satisfied at the Closing and which conditions would be satisfied or would be capable (assuming AEP Holdco or the Company has not breached the terms of this Agreement in a manner that would make such conditions incapable of being satisfied) of being satisfied if the Closing Date were the date on which such written notice is delivered) or that it is waiving any such unsatisfied conditions set forth in Section 6.1 and Section 6.2 and Investor is ready, willing and able to consummate the Closing and will consummate the Closing if AEP Holdco and the Company do, (iii) AEP Holdco fails to effect the Closing within two (2) Business Days after the delivery of such notice to AEP Holdco (or, if earlier, the Outside Date) and (iv) Investor stood ready, willing and able to consummate the Closing during such two (2) Business Day period.

Section 7.2Effect of Termination.

(a)In the event of the termination of this Agreement as provided in Section 7.1, written notice thereof shall be given by the terminating Party to the other Party or Parties (except in the event of a termination pursuant to Section 7.1(a)), specifying the provision hereof pursuant to which such termination is made, and, thereafter, this Agreement shall forthwith become null and void (other than this Section 7.2, Section 8.2 and Article X (excluding Section 10.12 except in relation to enforcement of any Surviving Provision), and Investor’s indemnification obligations under Section 5.2(b) (collectively, the “Surviving Provisions”), all of which shall survive termination of this Agreement), and there shall be no liability on the part of any Party under this Agreement other than in respect of the Surviving Provisions; provided, however, that except as set forth in (and subject in all respects to) Section 7.2(b), no Party shall be relieved or released from any Losses (which the Parties acknowledge and agree shall not be limited to reimbursement of out-of-pocket expenses, and, in the case of Liabilities or damages payable by Investor, would include the benefits of the transactions contemplated hereby lost by the Company and AEP Holdco (taking into consideration all relevant matters, including other investment opportunities and the time value of money)) arising out of any Fraud or Willful Breach of this Agreement by such Party. Except as set forth in (and subject in all respects to) Section 7.2(b), nothing in this Article VII shall prohibit any Party from seeking specific performance of the terms of this Agreement prior to the termination of this Agreement pursuant to, and on the terms and conditions of, Section 10.12. The Parties agree the sole remedy prior to the Closing or termination of this Agreement shall be to seek specific performance and neither Party shall be entitled to seek any claim for monetary damages.

(b)Notwithstanding anything to the contrary set forth in this Agreement, but subject to Section 10.12 and the last sentence of this Section 7.2(b), AEP Holdco and the Company, on behalf of themselves and the AEP Parent Group and each of their direct or indirect, former, current or future general or limited partners, stockholders, members, managers, directors, officers, employees, agents, Affiliates, Representatives or assignees (collectively, the “AEP Parent Related Parties”), agree that, if this Agreement is terminated, in no event shall Investor be liable for any Losses suffered by an AEP Parent Related Party as a result of any breach by Investor of this Agreement or any of the other Transaction Documents or the failure of the transactions contemplated by this Agreement to be consummated in excess of $141,000,000 (the “Cap”). Except as expressly set forth in the Equity Commitment Letters or the Guarantees, no Guarantors, any source or potential source of Equity Financing or Debt Financing, or any of their respective, direct or indirect, former, current or future general or limited partners, stockholders, members, managers, directors, officers, employees, agents, Affiliates, Representatives or assignees (collectively, the “Investor Related Parties”) shall have any liability or obligation relating to or arising out of this Agreement, any other Transaction Document or the transactions contemplated hereby or thereby. Notwithstanding anything to the contrary in this Agreement or any other Transaction Document, if this Agreement is terminated, in no event shall any member of the AEP Parent Related Parties seek or be entitled to recover from Investor (or any Investor Related Party), and each of AEP Holdco, the Company and its Subsidiaries, on behalf of itself and the AEP Parent Related Parties, hereby irrevocably waives and relinquishes any right to seek or recover, any damages in excess of the Cap from Investor (or any Investor Related Party). Notwithstanding anything to the contrary in this Agreement or any other Transaction Document, prior to the termination of this Agreement pursuant to Section 7.1, the right to specific performance pursuant to Section 10.12 shall constitute the sole and exclusive remedy of both the AEP Parent Related Parties against the Investor and the Investor Related Parties, on the one hand, and the Investor Related Parties against AEP Holdco, the Company and the AEP Parent Related Parties, as applicable, on the other hand, for any Losses in respect of this Agreement or any of the other Transaction Documents or the transactions contemplated hereby or any breach of this Agreement or any of the other Transaction Documents or the failure of the transactions contemplated hereby to be consummated.

(a)Subject to Section 8.1(b), each of the representations and warranties and the covenants and agreements (to the extent such covenant or agreement contemplates or requires performance by a Party prior to the Closing) of the Parties set forth in this Agreement or in any other document contemplated hereby (other than the Operating Agreement), or in any certificate delivered hereunder or thereunder (other than the Operating Agreement), will terminate effective immediately as of the Closing such that no claim for breach of any such representation, warranty, covenant or agreement, detrimental reliance or other right or remedy (whether in contract, in tort or at law or in equity) may be brought with respect thereto after the Closing, other than in respect of Fraud. In no event shall any Person be liable for the Fraud of any other Person, and a claim for Fraud may only be asserted against the Person that committed such Fraud.

(b)Each covenant and agreement that explicitly contemplates performance at or after the Closing, will, in each case and to the extent, survive for a period of thirty (30) days following the date on which the performance of such covenant or agreements is required to be completed, and nothing in this Section 8.1 will be deemed to limit any rights or remedies of any Person for breach of any such surviving covenant or agreement (it being understood that, except as set forth

in Section 7.2(b), nothing herein will limit or affect Investor’s liability for failure to pay the full Purchase Price and to pay any other amounts payable by it at or prior to the Closing as and when required by this Agreement). Notwithstanding anything to the contrary in this Agreement, nothing in this Section 8.1 shall affect or otherwise limit any claim made or available under an R&W Insurance Policy. Notwithstanding anything in this Agreement to the contrary but subject to Section 7.2(b), nothing in this Agreement shall limit the right of any Party with respect to any claims or remedies of a Party for Fraud.

(c)Investor and AEP Holdco acknowledge and agree, on their own behalf and on behalf of the Investor Group or the AEP Parent Group, as the case may be, that the agreements contained in this Section 8.1 are an integral part of the transactions contemplated hereby and that, without the agreements set forth in this Section 8.1, none of the Parties would enter into this Agreement.

Section 8.2No Additional Representations or Warranties; No Outside Reliance.

(a)Investor acknowledges and agrees, on behalf of itself and the Investor Group, that (i) the representations and warranties regarding the Company and its Subsidiaries expressly contained in Article II and regarding AEP Holdco expressly contained in Article III (collectively, the “Express Representations”) are the sole and exclusive representations, warranties and statements of any kind or nature made to Investor, any member of the Investor Group or any other Person related to them, (ii) except for the Express Representations, (A) none of AEP Holdco, the Company or any other Person on behalf of AEP Holdco or the Company makes, and neither Investor nor any member of the Investor Group has relied on or is relying on the accuracy or completeness of, or any other matter with respect to, any representation, warranty or statement of any kind or nature (whether in written, electronic or oral form) with respect to the Company, any of its Subsidiaries, AEP Holdco or otherwise, including any representation or warranty as to the quality, merchantability, fitness for a particular purpose or condition of the Company’s or its Subsidiaries’ businesses, operations, assets, liabilities, prospects or any portion thereof, (iii) except for the Express Representations, all representations, warranties and statements of any kind or nature (whether in written, electronic or oral form) are, in each case, specifically disclaimed by AEP Holdco and the Company on behalf of themselves and the AEP Parent Group and (iv) none of AEP Holdco, the Company or any other Person shall have or be subject to any liability whatsoever to Investor or any other Person resulting from the distribution to any member of the Investor Group of, or any member of the Investor Group’s use of or purported reliance on, any information (whether in written, electronic or oral form) provided by or on behalf of AEP Holdco other than the Express Representations, including the financial model, CIM, any information, statements, disclosures, documents or other materials made available in the Data Room, any projections, forward-looking statements or other forecasts (including in the financial model, CIM, Data Room, management meetings and similar items) (collectively, “Projections”) or otherwise in expectation of the transactions contemplated hereby or any discussions with respect to any of the foregoing information.

(b)Investor acknowledges and agrees, on behalf of itself and the Investor Group, that (i) Investor has conducted to its full satisfaction an independent investigation and verification of the business, financial condition, results of operations, assets, Liabilities, properties, Contracts and prospects of the Company and its Subsidiaries and (ii) in making its determination to proceed with the transactions contemplated hereby, Investor and the Investor Group have relied solely on the results of the Investor Group’s own independent investigation and verification, and have not relied on and are not relying on any member of the AEP Parent Group, the CIM, any information, statements, disclosures, documents or other materials made available in the Data Room, the Projections or any other information (whether in written, electronic or oral form), except for the Express Representations. Without limiting the generality of the foregoing and in no way limiting the Express Representations, Investor acknowledges and agrees, on its own

behalf and on behalf of the Investor Group, that (A) the Projections are being provided solely for the convenience of Investor to facilitate its own independent investigation of the Company and its Subsidiaries, (B) there are uncertainties inherent in attempting to make such Projections, (C) Investor is familiar with such uncertainties and (D) Investor is taking full responsibility for making its own evaluation of the adequacy and accuracy of all Projections (including the reasonableness of the assumptions underlying such Projections).

(c)Except for the representations and warranties expressly contained in Article IV, each of the Company and AEP Holdco acknowledges and agrees, on behalf of itself and the AEP Parent Group, that neither Investor nor any other Person on behalf of Investor makes, and none of the Company, AEP Holdco or any member of the AEP Parent Group has relied on or is relying on the accuracy or completeness of, any other express or implied representation, warranty or statement of any kind or nature with respect to Investor or any Affiliate of Investor or with respect to any other information provided to the Company and AEP Holdco by Investor or any of its Affiliates.

Whether or not the Closing takes place, except as otherwise expressly provided herein (including Section 5.3(a) and 9.1), each Party shall bear its own fees, costs and expenses (including fees, costs and expenses of Advisors) incurred in connection with the evaluation of the transactions contemplated hereby and with the negotiation of this

Section 10.5Assignment. This Agreement and all of the provisions hereof shall be binding upon and inure to the benefit of the Parties and their respective successors and permitted assigns; provided, that (a) neither this Agreement nor any of the rights, interests or obligations hereunder may be assigned or delegated without the prior written consent of all of the Parties, and (b) this Agreement shall not be assignable unless such prior written consent is so obtained, and any attempted or purported assignment hereof in the absence of such prior written consent shall be void ab initio; provided, however, that, prior to making the applications for Regulatory Approvals required to be made pursuant to Section 5.3, Investor may assign this Agreement to an Affiliate without consent so long as Investor remains liable for the performance of its obligations hereunder.

Section 10.6Amendment and Waiver. Any provision of this Agreement or the Disclosure Schedules or exhibits hereto may be (a) amended only in a writing signed by the Company, Investor and AEP Holdco or (b) waived only in a writing executed by the Person against which enforcement of such waiver is sought. No waiver of any provision hereunder or any breach or default thereof shall extend to or affect in any way any other provision or prior or subsequent breach or default. No failure or delay by any Party in exercising any right, power or privilege hereunder shall operate as a waiver thereof nor shall any single or partial exercise thereof preclude any other or further exercise thereof or the exercise of any other right, power or privilege. Notwithstanding anything to the contrary contained herein, Sections 5.5, 10.7, 10.17

and this sentence of Section 10.6 (and any other provision of this Agreement to the extent an amendment, supplement, waiver or other modification of such provision would modify the substance of such provision) may not be amended, supplemented, waived or otherwise modified in any manner that is adverse in any respect to the Financing Sources without the prior written consent of the Financing Sources.

Section 10.7Third Party Beneficiaries; Non-Recourse.

(a)Except as otherwise expressly provided herein (including as contemplated by Section 10.7(b) with respect to all Non-Parties), nothing expressed or referred to in this Agreement shall be construed to give any Person other than the Parties any legal or equitable right, remedy or claim under or with respect to this Agreement or any provision of this Agreement, except that the Financing Sources, if any, shall be express third party beneficiaries of Section 10.7, 10.17 and the last sentence of Section 10.6, in each case, to the extent contemplated thereby.

(b)This Agreement may only be enforced against, and any claim, action, suit, proceeding or investigation based upon, arising out of or related to this Agreement may only be brought against, the Persons that are expressly named as parties to this Agreement. Except to the extent named as a party to this Agreement, or, with respect to the Guarantors, as expressly contemplated in the Equity Commitment Letters or the Guarantees, and then only to the extent of the specific obligations of such Persons set forth herein and therein, no past, present or future shareholder, member, partner, manager, director, officer, employee, Affiliate, agent or Advisor of any Party, the Company or any Subsidiary of the Company (“Non-Parties”) shall have any liability (whether in contract, tort, equity or otherwise or by or through theories of equity, agency, control, instrumentality, alter ego, domination, sham, single business enterprise, piercing the veil, undercapitalization or any other attempt to avoid or disregard the entity form of any Person not a Party) for any of the representations, warranties, covenants, agreements or other obligations or Liabilities of any of the Parties or for any claim, action, suit, proceeding or investigation based upon, arising out of or related to this Agreement.

Section 10.8Severability. If any term, provision, covenant or restriction contained in this Agreement is held by a court of competent jurisdiction or other authority to be invalid, void, unenforceable or against its regulatory policy, the remainder of the terms, provisions, covenants and restrictions contained in this Agreement shall remain in full force and effect and shall in no way be affected, impaired or invalidated, and, to the extent permitted and possible, any invalid, void or unenforceable term shall be deemed replaced by a term that is valid and enforceable and that comes closest to expressing the intention of such invalid, void or unenforceable term.

Section 10.9Construction. The language used in this Agreement shall be deemed to be the language chosen by the Parties to express their mutual intent, and no rule of strict construction shall be applied against any Person. The headings of the sections and paragraphs of this Agreement have been inserted for convenience of reference only and shall in no way restrict or otherwise modify any of the terms or provisions hereof.

Section 10.10Disclosure Schedules. The Disclosure Schedules have been arranged for purposes of convenience in separately numbered sections corresponding to the sections of this Agreement. Any item or matter disclosed in any section or subsection of the Disclosure Schedules shall be deemed disclosed with respect to any other section or subsection of the Disclosure Schedules to the extent that the relevance of such item or matter to such other section or subsection is reasonably apparent on the face of such disclosure. The specification of any dollar amount or the inclusion of any item in the representations and warranties contained in this Agreement, the Disclosure Schedules or the attached exhibits is not intended to imply that the amounts, or higher or lower amounts, or the items so included, or other items, are or are not

required to be disclosed (including whether such amounts or items are required to be disclosed as material or threatened) or are within or outside of the Ordinary Course of Business, and no Party shall use the fact of the setting of the amounts or the fact of the inclusion of any item in this Agreement, the Disclosure Schedules or exhibits in any dispute or controversy between the Parties as to whether any obligation, item or matter not set forth or included in this Agreement, the Disclosure Schedules or exhibits is or is not required to be disclosed (including whether the amount or items are required to be disclosed as material or threatened) or are within or outside of the Ordinary Course of Business. In addition, matters reflected in the Disclosure Schedules are not necessarily limited to matters required by this Agreement to be reflected in the Disclosure Schedules. Such additional matters are set forth for informational purposes only and do not necessarily include other matters of a similar nature. No information set forth in the Disclosure Schedules shall be deemed to broaden in any way the scope of the Parties’ representations and warranties. Any description of any agreement, document, instrument, plan, arrangement or other item set forth on any Disclosure Schedule is a summary only and is qualified in its entirety by the terms of such agreement, document, instrument, plan, arrangement or item to the extent made available to Investor. The information contained in this Agreement, in the Disclosure Schedules and exhibits hereto 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 10.11Complete Agreement. This Agreement, together with the Confidentiality Agreements and any other agreements expressly referred to herein or therein, contains the entire agreement of the Parties respecting the sale and purchase of the Purchased Interests and the transactions contemplated hereby and supersedes all prior agreements among the Parties respecting the sale and purchase of the Purchased Interests.

Section 10.12Specific Performance.

(a)The Parties agree that irreparable damage, for which monetary relief, even if available, may not be an adequate remedy, may occur in the event that any provision of this Agreement is not performed in accordance with its specific terms or is otherwise breached, including if any Party fails to take any action required of it hereunder to consummate the transactions contemplated hereby. It is accordingly agreed that (i) the Parties shall be entitled to seek an injunction or injunctions, specific performance or other equitable relief to prevent breaches of this Agreement and to enforce specifically the terms and provisions hereof in the courts described in Section 10.13 without proof of damages or otherwise, this being in addition to any other remedy to which they are entitled under this Agreement, and (ii) the right of specific performance and other equitable relief is an integral part of the transactions contemplated hereby, and without that right, none of the Parties would have entered into this Agreement. The Parties acknowledge and agree that any Party pursuing an injunction or injunctions or other Order to prevent breaches of this Agreement and to enforce specifically the terms and provisions of this Agreement in accordance with this Section 10.12 shall not be required to provide any bond or other security in connection with any such Order. The remedies available to the Parties pursuant to this Section 10.12 shall be in addition to any other remedy to which they may be entitled at law or in equity, and the election to pursue an injunction or specific performance shall not restrict, impair or otherwise limit any Party from seeking to collect or collecting damages. Each of the Parties agrees that it shall not oppose the granting of an injunction, specific performance and other equitable relief on the basis that any other Party has an adequate remedy at law or that any award of specific performance is not an appropriate remedy for any reason at law or in equity. If, prior to the Outside Date, any Party brings any action, in each case in accordance with Section 10.13, to enforce specifically the performance of the terms and provisions hereof by any other Party, the Outside Date shall, solely for the benefit of the Party or Parties seeking relief and not for the benefit of the other Parties, automatically be extended (x) for the period during which such action is pending, plus ten (10) Business Days or (y) by such other time period established

by the court presiding over such action, as the case may be. The Parties further agree that nothing set forth in this Section 10.12 shall require any Party to institute any action for (or limit any Party’s right to institute any action for) specific performance under this Section 10.12 prior or as a condition to exercising any termination right under Article VII (and pursuing available remedies, including damages, after such termination). Notwithstanding the foregoing or anything else to the contrary in this Agreement, this Section 10.12(a) shall in all circumstances by subject to Section 10.12(b).

(b)Notwithstanding anything to the contrary in this Agreement, AEP Holdco and the Company shall not be entitled to specific performance or any other equitable relief in order to cause Investor to consummate the transactions contemplated by this Agreement or the other Transaction Documents to occur at the Closing unless and only if:

(i)all of the conditions set forth in Section 6.1 and Section 6.2 have been satisfied or (to the extent permitted by Law) waived (other than those conditions that, by their nature are to be satisfied at the Closing, so long as such conditions would be satisfied at such time if specific performance was granted pursuant to this Section 10.12(b)) at the time the Closing is required to occur pursuant to Section 1.3 and there is no state of facts or circumstances that would cause the conditions in Section 6.1 and Section 6.2 not to be satisfied on or prior to the Outside Date;

(ii)Investor has failed to complete the Closing within two (2) Business Days following the date the Closing is required to occur pursuant to Section 1.3; and
