(d) If Seller duly and timely delivers a notice of disagreement pursuant to Section 2.4(c), IPH and Seller shall, during the 30 days following such delivery (the “Resolution Period”), use their commercially reasonable efforts to reach agreement on the disputed items or amounts. If at the conclusion of the Resolution Period there are any amounts remaining in dispute, then all amounts remaining in dispute shall be promptly submitted to KPMG LLP (the “Neutral Auditors”) for the purpose of calculating such amounts that remain in dispute. If KPMG LLP is unwilling or unable to serve as the Neutral Auditors and Seller and IPH are unable to agree on the Neutral Auditors within 15 days after the expiration of the Resolution Period, then Seller and IPH shall each have the right to request the American Arbitration Association to appoint the Neutral Auditors who in any event shall not be the current auditors of Seller or IPH. Each party agrees to execute, if requested by the Neutral Auditors, a reasonable engagement letter. All fees and expenses relating to the work, if any, to be performed by the Neutral Auditors (i) shall be borne by IPH in the proportion that the aggregate dollar amount of such items so submitted that are successfully disputed by Seller (as finally determined by the Neutral Auditors) bears to the aggregate dollar amount of all items so submitted and (ii) shall be borne by Seller in the proportion that the aggregate dollar amount of such disputed items so submitted that are unsuccessfully disputed by Seller (as finally determined by the Neutral Auditors) bears to the aggregate dollar amount of all items so submitted. The Neutral Auditors shall act as an arbitrator to determine, based solely on presentations by Seller and IPH, and not by independent review, only those issues still in dispute. The Neutral Auditors’ determination of any disputed amount shall not be higher than the highest amount proposed by either party or lower than the lowest amount proposed by either party. The Neutral Auditors’ determination shall be made within 45 days of their selection, shall be set forth in a written statement delivered to Seller and IPH and shall be final, binding and conclusive. The term “Adjusted Closing Statement,” as used herein, shall mean the definitive Closing Statement agreed or the definitive Closing Statement resulting from the determinations made by the Neutral Auditors in

-22-

accordance with this Section 2.4(d) (in addition to those items theretofore agreed to by Seller and IPH).

(e) During the period of IPH’s preparation of the Closing Statement, the period of Seller’s review of the Closing Statement and the period of any dispute within the contemplation of this Section 2.4, Seller and IPH shall, and IPH shall cause the Transferred Company and its Subsidiaries to, cooperate reasonably and provide each other and the Neutral Auditors on a timely basis access during normal business hours to their respective books, records and personnel to the extent reasonably requested by Seller, IPH or the Neutral Auditors, as applicable, and necessary or useful in making the presentations and determinations contemplated in Section 2.4(d), in Seller’s review of the Closing Statement contemplated in Section 2.4(c) and in IPH’s preparation of the Closing Statement contemplated in Section 2.4(a) and in accordance with, and subject to, Section 5.1(a) and Section 5.1(b), as applicable.

(f) If the Applicable Amount shown on the Adjusted Closing Statement exceeds the Target Applicable Amount, IPH shall pay AER (or, if AER is no longer in existence at such time, Seller) such excess, and if the Applicable Amount shown on the Adjusted Closing Statement is less than the Target Applicable Amount, Seller shall cause AER (or, if AER is no longer in existence at such time, Seller) to pay IPH such shortfall. Any payments which are made pursuant to this Section 2.4 shall bear interest at 3% per annum from (and including) the Closing Date to (and including) the date of such payment. Any payments made pursuant to this Section 2.4 and the interest thereon shall be paid by wire transfer in immediately available funds to an account specified by the party to this Agreement not making such payment within five Business Days after the Adjusted Closing Statement is agreed or deemed to have been agreed to by IPH and Seller or the written statement of the Neutral Auditors setting forth their determination regarding any remaining items in dispute is delivered to Seller and IPH. Except as otherwise required pursuant to a Determination, for all Tax purposes, any payments made pursuant to this Section 2.4(f) shall be treated as an adjustment to the Consideration.

(g) IPH shall be entitled to deduct and withhold from payment of the Consideration, or any other amounts (or any portion thereof) payable pursuant to this Agreement, such amounts as are required to be deducted and withheld with respect to the making of such payment under the Code or any other applicable Tax Law. To the extent that amounts are so withheld and timely remitted by the withholding party to the appropriate Governmental Entity, such withheld and remitted amounts shall be treated for all purposes of this Agreement as having been paid to the Person with respect to whom such withholding was made.

(h) Notwithstanding anything to the contrary in this Agreement, the following shall not be treated as Cash or otherwise taken into account for purposes of determining the Applicable Amount or the Closing Statement: (i) the amount of any Insurance Proceeds, (ii) the Marketing Company Note, (iii) the Post-Closing Credit Support, (iv) the AERG Retained Cash, (v) the Genco Retained Cash, (vi) the AEM

-23-

Retained Cash and (vii) Cash held by the Transferred Company or its Subsidiaries in an amount equal to the positive fair market value of the positions held by the Transferred Company or any of its Subsidiaries associated with Seller’s removal of 2016 hedging positions as permitted by Section 5.9(e).

(g) No Transferred Company Employee or EEI Employee participates in a Multiemployer Plan or in a plan that has two or more contributing sponsors at least two of whom are not under common control, within the meaning of Section 4063 of ERISA.

-30-

behalf of any employee, prospective employee, former employee, retiree, labor organization or other employee representative.

(k) Except as would not reasonably be expected to result in liability to the Transferred Company and its Subsidiaries, the Transferred Company and its Subsidiaries are in material compliance with all applicable laws respecting employment and employment practices, including, without limitation, all laws respecting terms and conditions of employment, health and safety, wages and hours, child labor, immigration, employment discrimination, disability rights or benefits, equal opportunity, plant closures and layoffs, affirmative action, workers’ compensation, labor relations, employee leave issues and unemployment insurance.

(m) Neither the execution of this Agreement, the Transitional Services Agreement, nor the consummation of the transactions contemplated hereby and thereby will result in any breach or other violation of any collective bargaining agreement, employment agreement or any other labor-related agreement to which the Transferred Company or its Subsidiaries is a party.

(n) Except as would not reasonably be expected to result in liability to the Transferred Company and its Subsidiaries, there are no pending or, to the Knowledge of Seller, threatened claims by or on behalf of any of the Transferred Company Benefit Plans or by any employee or beneficiary covered under any Transferred Company Benefit Plan in such capacity (other than routine claims for benefits).

(o) No Benefit Plan provides welfare benefits, including death or medical benefits (whether or not insured), with respect to Transferred Company

-31-

Employees or EEI Employees or any other individuals previously employed in respect of the Business beyond their retirement or other termination of service, other than (i) coverage mandated solely by applicable Law; (ii) death benefits or retirement benefits under any “employee pension benefit plan” (as defined in Section 3(2) of ERISA); (iii) benefits the full costs of which are fully provided for by insurance; or (iv) benefits the full costs of which are borne by such individual or his or her beneficiary.

Subject to the representations, warranties, agreements and covenants contained in this Agreement, IPH confirms that it has made an independent investigation, analysis and evaluation of the Transferred Company and its Subsidiaries and their properties, assets, business, financial condition, prospects, documents, information and records. IPH is acquiring the Interests for investment and not with a view toward or for sale in connection with any distribution thereof, or with any present intention of distributing or selling the Interests. IPH acknowledges that the Interests have not been registered under the Securities Act or any state securities Laws, and agrees that the Interests may not be sold, transferred, offered for sale, pledged, hypothecated or otherwise disposed of without registration under the Securities Act, except pursuant to an exemption from such registration available under the Securities Act, and without compliance with foreign securities Laws, in each case, to the extent applicable.

Section 4.6 Inspections; Limitation of Seller’s Warranties. Except as otherwise expressly set forth in this Agreement, the Interests, the EEI Capital Stock, the Business and the properties of the Transferred Company and its Subsidiaries are furnished “AS IS,” “WHERE IS” AND, SUBJECT TO THE REPRESENTATIONS AND WARRANTIES CONTAINED IN ARTICLE III AND THE TRANSITIONAL SERVICES AGREEMENT, WITH ALL FAULTS AND WITHOUT ANY OTHER REPRESENTATION OR WARRANTY OF ANY NATURE WHATSOEVER, EXPRESS OR IMPLIED, ORAL OR WRITTEN, AND IN PARTICULAR, WITHOUT ANY IMPLIED WARRANTY OR REPRESENTATION AS TO CONDITION, MERCHANTABILITY OR SUITABILITY AS TO ANY OF THE ASSETS OR PROPERTIES OF THE TRANSFERRED COMPANY AND ITS SUBSIDIARIES.

Section 4.7 No Regulatory Impediment. To the Knowledge of IPH, there is no material fact relating to IPH or any of its Affiliates’ respective businesses, operations, financial condition or legal status, including any officer’s, director’s or current employee’s status, that would reasonably be expected to impair the ability of the parties to this Agreement to obtain, on a timely basis, any authorization, consent, Order, declaration or approval of, or ability to contract with, any Governmental Entity or third party necessary for the consummation of the transactions contemplated by this Agreement.

Section 4.8 Regulatory Status. IPH is not a “public utility” as defined in the FPA. Section 4.8 of the IPH Disclosure Schedule identifies each of IPH’s “affiliates” (under and as defined in the FPA and the rules and regulations of FERC promulgated thereunder) that are “public utilities” as defined in the FPA and are subject to regulation by FERC as public utilities. Each of IPH’s “affiliates” (under and as defined in the FPA and the rules and regulations of FERC promulgated thereunder) selling electric energy, capacity and certain ancillary services at wholesale subject to the jurisdiction of FERC under the FPA has been authorized by FERC to make wholesale sales of electric energy, capacity and/or certain ancillary services at market-based rates pursuant to Section 205 of the FPA, except for any such affiliate that owns one or more “qualifying facilities” as defined in the FERC rules and regulations promulgated under the Public Utility Regulatory Policies Act of 1978, as amended, that are entitled to exemption from regulation under Section 205 of the FPA. IPH is not subject to regulation as a “public utility” or “public service company” (or similar designation) with respect to its rates, securities issuances, capital structure or other matters by any state Governmental Entity.

Section 4.9 Absence of Arrangements with Management. As of the date of this Agreement, there are no contracts, undertakings, commitments, agreements or obligations or understandings between IPH or any of its Affiliates, on the one hand, and any member of the Transferred Company’s management or directors or any of their respective Affiliates (other than Seller), on the other hand, relating to the transactions contemplated by this Agreement or the operations of the Transferred Company after the Closing Date.

Section 4.10 No Competing Business. Neither IPH nor any of IPH’s “affiliates” (under and as defined in the FPA and the rules and regulations of FERC promulgated thereunder) owns or operates “inputs to electric power production” as defined in 18 C.F.R. 35.36(a)(4), except sites for generation capacity development that have been or will be reported to FERC in accordance with FERC’s rules and regulations.

Section 4.11 Guaranty. Concurrently with the execution of this Agreement, Parent has delivered to Seller the Parent Guaranty, dated as of the date hereof, in favor of Seller. The Parent Guaranty is in full force and effect. No event has occurred which, with or without notice, lapse of time or both, would constitute a default on the part of Parent under the Parent Guaranty.

Section 4.12 No Other Representations and Warranties. Except for the representations and warranties contained in this Agreement, none of IPH, its Subsidiaries or any of their respective agents, Affiliates, officers, directors, employees, agents, representatives, or any other Person, makes or shall be deemed to make any representation or warranty to Seller, express or implied, at law or in equity, on behalf of IPH or its Subsidiaries or any Affiliate of IPH or its Subsidiaries, and IPH, its Subsidiaries and each of their respective Affiliates by this Agreement disclaim any such representation or warranty, whether by IPH, its Subsidiaries, or any of their respective agents, Affiliates, officers, directors, employees, agents or representatives or any other Person, notwithstanding the delivery or disclosure to Seller, or any of its officers, directors, employees, agents or representatives or any other Person of any documentation or other information by IPH, its Subsidiaries or any of their respective agents, Affiliates, officers, directors, employees, agents or representatives or any other Person with respect to any one or more of the foregoing.

Notwithstanding the foregoing, Seller shall not be required to provide access to any books and records, data or other information the disclosure of which would (i) unreasonably disrupt the operations of the Company or any of its Subsidiaries; (ii) cause a violation of any agreement to which the Company or any of its Subsidiaries is a party; or (iii) in the reasonable opinion of counsel to Seller, result in the loss of any existing attorney-client privilege with respect to such books and records, data or other information or violate any Law to which Seller or any of its Subsidiaries, or any of its or their respective properties, rights or assets, is subject (provided that the parties hereto will cooperate to make appropriate substitute disclosure arrangements, or seek appropriate waivers or consents, under circumstances in which the restrictions of this sentence apply).

(b) At and after the Closing, IPH shall, and shall cause its Subsidiaries to, afford Seller and its representatives, during normal business hours, upon reasonable notice, reasonable access to the books, records, Environmental Records, properties and employees of the Transferred Company and its Subsidiaries to the extent that such access may be reasonably requested by Seller, including in connection with financial statements and SEC reporting obligations or in the event of litigation; provided, however, that nothing in this Agreement shall limit any of Seller’s rights of discovery. Notwithstanding the foregoing, IPH shall not be required to provide access to any books and records, data or other information the disclosure of which would, in the reasonable opinion of counsel to IPH, result in the loss of any existing attorney-client privilege with respect to such books and records, data or other information or violate any Law to which IPH, the Transferred Company or any of its Subsidiaries, or any of its or their respective properties, rights or assets, is subject (provided that the parties hereto will cooperate to make appropriate substitute disclosure arrangements, or seek appropriate waivers or consents, under circumstances in which the restrictions of this sentence apply).

such access may be reasonably requested by IPH, including in connection with insurance loss and claim data, financial statements and SEC reporting obligations or in the event of litigation; provided, however, that nothing in this Agreement shall limit any of IPH’s rights of discovery. Notwithstanding the foregoing, Seller shall not be required to provide access to any books and records, data or other information the disclosure of which would, in the reasonable opinion of counsel to Seller, result in the loss of any existing attorney-client privilege with respect to such books and records, data or other information or violate any Law to which Seller or any of its Subsidiaries, or any of its or their respective properties, rights or assets, is subject (provided that the parties hereto will cooperate to make appropriate substitute disclosure arrangements, or seek appropriate waivers or consents, under circumstances in which the restrictions of this sentence apply).

(c) IPH agrees to hold all the books and records of the Transferred Company and its Subsidiaries existing on the Closing Date that are in the possession of the Transferred Company and its Subsidiaries and not to destroy or dispose of any thereof for a period of 10 years from the Closing Date or such longer time as may be required by Law; provided, however, that no later than 30 days prior to such destruction or disposition, Seller may request in writing copies of all books and records of the Transferred Company and its Subsidiaries existing on the Closing Date.

IPH shall have the right to appoint an individual who will exercise the rights granted to IPH pursuant to this Section 5.1(d) and as further set forth on Section 5.1(d) of the IPH Disclosure Schedule. No information made available to IPH, its monitor, or any other individual or entity pursuant to this Section 5.1 shall be made available to any employee of IPH or its affiliates (as that term is defined under FERC regulations) which employee engages in, or directs, oversees or executes, the sale, marketing, or trading of physical electricity or financial electricity derivative products.

Section 5.2 Confidentiality.

(a) The terms of the Confidentiality Agreement are incorporated into this Agreement by reference and shall continue in full force and effect until the Closing and apply to IPH to the same extent they are applicable to Parent, at which time the confidentiality obligations under the Confidentiality Agreement shall terminate; provided, however, that IPH’s confidentiality obligations with respect to

-48-

disclosure (but not use) of Evaluation Material (as defined in the Confidentiality Agreement) shall terminate only in respect of that portion of the Evaluation Material exclusively relating to the Business, and the confidentiality obligations not relating exclusively to the Business shall continue in full force and effect for a period of 12 months following the Closing Date. If, for any reason, the Transaction is not consummated, the Confidentiality Agreement shall continue in full force and effect for a period of 12 months following the termination of this Agreement.

(b) Subject to Seller’s confidentiality obligations under the Transitional Services Agreement, Seller acknowledges that it shall not, and it shall cause its Subsidiaries not to, for a period of two years after the Closing Date, disclose any information that would be deemed Evaluation Material under the Confidentiality Agreement and which relates to the Business to anyone other than to representatives of IPH or the Transferred Company and its Subsidiaries, except for any such information that does not relate primarily to the Business or which is requested by any Governmental Entity or that is required by applicable Law to be disclosed by it in connection with any Action, and then, if permitted by Law, only after Seller has given written notice to IPH of its obligation to disclose such information (provided that no such notice is required in connection with a routine audit or examination by, or a blanket document request from, a Governmental Entity) so that IPH may waive compliance with the provisions of this Section 5.2(b) or be given an opportunity to obtain an appropriate protective order with respect to such disclosure, and Seller shall reasonably cooperate with IPH in connection with obtaining such protective order; provided that, if in the absence of a protective order or the receipt of a waiver from IPH, Seller has been advised by legal counsel that it is required to disclose such information, Seller may disclose such information.

(c) Notwithstanding the above or the Confidentiality Agreement, nothing in this Agreement or the Confidentiality Agreement shall prevent the Parent or any of its Subsidiaries from disclosing any information, including Required Financial Information, (i) to any Debt Financing Source in connection with any Debt Financing, (ii) in an offering circular, prospectus, bank book or private placement memorandum in connection with any Debt Financing, (iii) for the purposes of establishing a “due diligence” defense in connection with any Debt Financing, (iv) with Seller’s consent, as applicable or (v) in connection with Parent’s reporting obligations under the Exchange Act and its obligations under the Securities Act, including, but not limited to, its obligation to maintain the effectiveness of its shelf registration statement on Form S-1. No information made available to IPH, its monitor, or any other individual or entity pursuant to this Section 5.2 shall be made available to any employee of IPH or its affiliates (as that term is defined under FERC regulations) which employee engages in the sale, marketing, or trading of physical electricity or financial electricity derivative products. In addition to, and not in limitation of, the above, in furtherance of Seller’s obligations under Section 5.14, Parent or any of its Subsidiaries may disclose any information, including Evaluation Material, to any Debt Financing Source involved in the preparation of the Required Information to the extent reasonably necessary to perform any diligence with respect to, or confirm the accuracy of, the Required Financial Information, in each case subject to (x) Seller’s prior consent (not

-49-

to be unreasonably withheld) and (y) the recipient of such information being subject to the confidentiality obligations under the Confidentiality Agreement and this Agreement).

Section 5.3 Efforts.

(a) Each of the parties agrees to use its reasonable best efforts to take, or cause to be taken, all actions, to file, or cause to be filed, all documents and to do, or cause to be done, all things necessary, proper or advisable to consummate the transactions contemplated by this Agreement as promptly as practicable, including preparing and filing as promptly as practicable all documentation to effect all necessary filings, consents, waivers, approvals, authorizations, permits or orders from all Governmental Entities. In furtherance and not in limitation of the foregoing, each party hereto agrees (i) to cooperate and use best efforts to prepare filings necessary to receive the Pre-Closing FERC Approval; (ii) to cooperate and use best efforts to prepare filings necessary to receive any requisite clearance under any investigation by any Governmental Entity under any antitrust, competition or regulatory statute; and (iii) to cooperate and use best efforts to prepare filings necessary to receive the FCC Approval; and Seller further agrees to seek any waivers, satisfy or otherwise settle any fines or forfeitures, required because of past actions or omissions of Seller or any Affiliate of Seller that may be necessary to acquire the FCC Approval.

(b) Further, and without limiting the generality of the rest of this Section 5.3, each of the parties shall cooperate in all respects with each other in connection with any filing or submission and in connection with any investigation or other inquiry and shall promptly, subject to applicable Law (i) furnish to the other such necessary information and reasonable assistance as the other parties may request in connection with the foregoing; (ii) inform the other of any material communication from any Governmental Entity regarding any of the transactions contemplated by this Agreement; and (iii) provide counsel for the other party with copies of all filings made by such party, and all correspondence between such party (and its advisors) with any Governmental Entity and any other information supplied by such party and such party’s Subsidiaries to a Governmental Entity or received from such a Governmental Entity in connection with the transactions contemplated by this Agreement; provided, however, that materials may be redacted (A) to remove references concerning the valuation of the Transferred Company, its Subsidiaries and the Business and (B) as necessary to comply with contractual arrangements. Each party hereto shall, subject to applicable Law, permit counsel for the other parties to review in advance, and consider in good faith the views of the other parties in connection with, any proposed written communication to any Governmental Entity in connection with the transactions contemplated by this Agreement. The parties agree not to participate, or to permit their Subsidiaries to participate, in any substantive meeting or discussion, either in person or by telephone, with any Governmental Entity in connection with the transactions contemplated by this Agreement unless it consults with the other party in advance and, to the extent not prohibited by such Governmental Entity, gives the other party the opportunity to attend and participate. IPH shall take the lead in determining strategy for and conducting such meetings. IPH and Seller will consult and cooperate

-50-

with one another in connection with any analyses, appearances, presentations, memoranda, briefs, arguments, opinions and proposals made or submitted by or on behalf of any party in connection with proceedings under or relating to any investigation by any Governmental Entity under any antitrust, competition or regulatory statute, the FPA or the IPCB. Subject to the foregoing, IPH shall take the lead in scheduling and conducting any meeting with any Governmental Entity, coordinating any filings, obtaining any necessary approvals, and resolving any investigation or other inquiry of any such agency or other Governmental Entity under any investigation by any Governmental Entity under any antitrust, competition or regulatory statute or the FPA, including the timing of the initial filing, which will be made as promptly as practicable after the date of this Agreement. Notwithstanding anything to the contrary in this paragraph, Seller shall have the sole authority to approve any concessions, conditions, commitments, or other actions to satisfy FERC to secure approval of the transactions contemplated by this Agreement (including the transactions contemplated by the Put Option Agreement), if such concessions, conditions, commitments, or other actions materially adversely impact Seller and/or its Affiliates and Subsidiaries (other than the Transferred Company or its Subsidiaries) following the Closing.

(c) Further, and without limiting the generality of the rest of this Section 5.3, IPH shall take any and all steps necessary to avoid or eliminate each and every impediment arising during regulatory review by FERC or any other Governmental Entity under any antitrust, competition, or trade regulation or similar Law that may be asserted by any Governmental Entity or private party with standing under such Law with respect to this Agreement so as (x) to make effective as promptly as practicable the transactions contemplated by this Agreement and (y) to avoid any suit or proceeding by any Governmental Entity, which would otherwise have the effect of preventing or delaying the Closing beyond the Outside Date; provided, however, that this Section 5.3(c) shall not apply to the IPCB as it relates to the Air Variance for which Section 5.15 shall govern. The steps involved to achieve the objectives set forth in the preceding sentence shall include, without limitation, (i) defending through litigation on the merits, including appeals, any claim asserted in any court or other proceeding by any party; (ii) proposing, negotiating, committing to and effecting, by consent decree, hold separate order or otherwise, the sale, divestiture or disposition of such assets or businesses of IPH (including its Subsidiaries) or the Transferred Company (including its Subsidiaries), including entering into customary ancillary agreements on commercially reasonable terms relating to any such sale, divestiture or disposition of such assets or businesses; (iii) agreeing to any limitation on the conduct of IPH (including its Subsidiaries) and the Transferred Company (including its Subsidiaries); (iv) proposing, negotiating, committing to and effecting the sale or divestiture of the EEI Capital Stock held by Genco; or (v) agreeing to take any other action as may be required by a Governmental Entity in order (A) to obtain all necessary consents, approvals and authorizations as soon as reasonably possible, and in any event before the Outside Date, (B) to avoid the entry of, or to have vacated, lifted, dissolved, reversed or overturned any decree, judgment, injunction or other Order, whether temporary, preliminary or permanent, that is in effect in any Action

-51-

and that prohibits, prevents or restricts consummation of the transactions contemplated by this Agreement or (C) to effect the expiration or termination of any waiting period, which would otherwise have the effect of preventing or delaying the Closing beyond the Outside Date. At the request of IPH, Seller shall agree to take, or cause the Transferred Company to take, in Seller’s sole discretion, any action with respect to the Transferred Company, any of their respective Subsidiaries or the EEI Capital Stock in the two preceding sentences; provided that any such action is conditioned upon (and shall not be completed prior to) the consummation of the transactions contemplated by this Agreement. IPH shall not, and shall cause its Subsidiaries and Affiliates not to, take any action which is intended to, or which would reasonably be expected to, adversely affect the ability of any of the parties to obtain (or cause delay in obtaining) any necessary approvals of any Governmental Entity required for the transactions contemplated by this Agreement, from performing its covenants and agreements under this Agreement, or from consummating the transactions contemplated by this Agreement.

(d) Further, and without limiting the generality of the rest of this Section 5.3, but subject to IPH’s right to take the lead in obtaining any necessary approvals to consummate the transactions contemplated by this Agreement as contemplated by the penultimate sentence of Section 5.3(b), Seller shall, and shall cause Genco and Medina Valley, to take, or cause to be taken, all actions, to file, or cause to be filed, all documents and to do, or cause to be done, all things necessary, proper or advisable to consummate the transactions contemplated by the Put Option Agreement as promptly as practicable, including preparing and filing as promptly as practicable all documentation to effect all necessary filings, consents, waivers, approvals, authorizations, permits or orders from all Governmental Entities.

(e) Notwithstanding any provision in this Agreement to the contrary, neither Seller nor Parent shall be required to propose, negotiate, commit to or effect, by consent decree, hold separate order or otherwise, the sale, divestiture or disposition of any assets or businesses of Seller or Parent (including their respective Subsidiaries other than, for the avoidance of doubt, IPH (including its Subsidiaries) or the Transferred Company (including its Subsidiaries)).

Section 5.4 Interim Operations.

(b) Notwithstanding the above provisions of this Section 5.4, prior to Closing, Seller may, and may cause its Affiliates to, remove all Cash from the Transferred Company or any of its Subsidiaries to Seller or its Subsidiaries, in such manner as Seller shall determine (provided that it does not violate any existing contractual obligations, including the Indenture); provided that (i) Seller may not permit the distribution or dividend of any assets (other than Cash in accordance with this Section 5.4(b)) or properties of the Transferred Company and its Subsidiaries to any of the Transferred Company’s equity holders, (ii) Seller may not remove from the Transferred Company or any of its Subsidiaries any Insurance Proceeds and must leave at the Transferred Company and its Subsidiaries an amount in Cash equal to, and must maintain in segregated accounts for the benefit of the Transferred Company or its applicable Subsidiary, all such Insurance Proceeds, (iii) in addition to any aggregate Cash amount to be transferred to Genco pursuant to Section 5.7, Seller shall cause to be retained at Closing at Genco an aggregate amount of Cash equal to the sum of (w) $70,000,000, (x) the Put Option Down Payment ($100,000,000), (y) the Put Option Additional Purchase Price (in an amount equal to at least $33,000,000) and (z) the amount, if any, by which the Alternative Gas Plant Transaction Consideration exceeds the sum of (A) the Put Option Down Payment and (B) the Put Option Additional Purchase Price (subject to the proviso in the first sentence of Section 5.24(d)) (such sum, the “Genco Retained Cash”), (iv) Seller shall cause to be retained at Closing at AERG an aggregate amount in Cash equal to $7,689,000 (or the gross proceeds of the sales described in item (i) on Section 3.7(a) of the Seller Disclosure Schedule to the extent completed at Closing) (the “AERG Retained Cash”) and (v) Seller shall cause to be retained at Closing at AEM an aggregate amount of Cash equal to $15,000,000 (the “AEM Retained Cash”). Notwithstanding anything to the contrary herein or elsewhere, but subject to Section 5.9(a), for the avoidance of doubt, Seller shall have the right to any Cash or instrument posted as collateral, which right shall be considered in the Marketing Company Note.

Section 5.9 Guarantees; Commitments.

(a) Following the Closing until the earlier of (i) the date that is 24 months after the Closing Date and (ii) the date on which, pursuant to the applicable Contract, Credit Support is no longer required to be delivered (the “Specified Period”), Seller shall (x) maintain in effect without amendment all of its financial obligations in existence as of the Closing under all Credit Support with respect to the Transferred Company and its Subsidiaries (including, for the avoidance of doubt and without limitation, any cash loaned to Marketing Company by Seller or its Affiliates (other than the Transferred Company and its Subsidiaries) to post as collateral) (such financial obligations in existence as of the Closing, the “Specified Financial Obligations” ) for the durations contemplated thereby (but in no event beyond the Specified Period) and (y) provide any additional Credit Support that may be contractually required pursuant to any of the Contracts of the Transferred Company or any of its Subsidiaries as of Closing, in the case of each of clauses (x) and (y) in accordance with the terms thereof as in effect as of the Closing and only with respect to the underlying obligations existing as of the Closing (collectively, the “Post-Closing Credit Support” ). For the avoidance of doubt, (i) the Post-Closing Credit Support shall not be taken into account for purposes of determining the Applicable Amount or the Closing Statement and (ii) nothing in this Section 5.9(a) shall require Seller to extend the term of any Post-Closing Credit Support beyond the date on which such Post-Closing Credit Support would otherwise expire in accordance with the terms thereof.

(b) At and after the Closing, IPH, the Transferred Company and its and their respective Subsidiaries, jointly and severally, shall forever indemnify, defend and hold harmless Seller and any of its Affiliates against any Losses (including out-of-pocket costs or expenses in connection with such Post-Closing Credit Support) that Seller or any of its Affiliates suffers, incurs or is liable for by reason of or arising out of or in consequence of: (i) Seller or any of its Affiliates issuing, making payment under, being required to pay or reimburse the issuer of, or being a party to, any Post-Closing Credit Support; (ii) any claim or demand for payment made on Seller or any of its Affiliates with respect to any of the Post-Closing Credit Support; or (iii) any Action, claim or proceeding by any Person who is or claims to be entitled to the benefit of or claims to be entitled to payment, reimbursement or indemnity with respect to any Post-Closing Credit Support, in each case other than a Loss (including

-58-

out-of-pocket costs or expenses in connection with such Post-Closing Credit Support) by reason of or arising out of or in consequence of (x) an action or inaction by Seller or any of its Affiliates prior to Closing that, prior to the Closing, triggered and then results in a right (whether or not exercised prior to Closing) by a counterparty to any Credit Support to demand Seller or any of its Affiliates issue, make payment under, be required to pay or reimburse such counterparty for any amounts owed under such Credit Support, (y) the breach by Seller of this Section 5.9 or (z) any event of default or other termination event occurring following the Closing with respect to any member of the Seller Group that results in a right by a counterparty to any Credit Support to demand Seller or any of its Affiliates issue, make payment under, be required to pay or reimburse such counterparty for any amounts owed under such Credit Support. Except as contemplated by Section 5.9(a), at the Closing and continuing thereafter, none of IPH or its Affiliates shall enter into any transactions, trades, confirmations or other agreements or arrangements pursuant to which any payment, reimbursement or other obligation would be required under any Post-Closing Credit Support or otherwise be an obligation of Seller or its Affiliates.

(c) Further, and without limiting the indemnification obligations of IPH, the Transferred Company and its and their respective Subsidiaries pursuant to Section 5.9(b), in exchange for (i) Seller agreeing to provide value to the Transferred Company or one of its Subsidiaries, as applicable, through the Post-Closing Credit Support provided for under Section 5.9 (a), and (ii) the promises of, and other good and valuable consideration provided by, Seller, in each case as set forth herein and in connection herewith, IPH shall cause each of New AERG and Genco to provide a guaranty, in each case, substantially in the form of Exhibit F (the “New AERG Guaranty” and the “Genco Guaranty”, respectively ) and guarantying (A) the repayment of any amounts owed by IPH, the Transferred Company or any of their respective Subsidiaries pursuant to Section 5.9(b) and (B) any indemnification obligations of IPH pursuant to Section 7.2(a)(y) or 10.2(a)(iv) ((A) and (B) collectively “Indemnification Payments”); it being understood that the Genco Guaranty will only guarantee such Indemnification Payments to the extent not prohibited by the Indenture as in effect as of the date hereof. The Genco Guaranty shall be secured by a first-priority perfected security interest (subject to Permitted Liens) in the assets listed in Section 5.9(c)(i) of the Seller Disclosure Schedule only to the extent: (1) permitted by applicable Law and existing contractual obligations of the Transferred Company, its Subsidiaries or their respective assets and (2) the granting of such security interest in Genco’s assets would not require the grant of any security interest in such assets by Genco to any person (other than Seller) pursuant to any existing contractual obligation of Genco. The AERG Guaranty shall be secured by a first-priority perfected security interest (subject to Permitted Liens and only to the extent permitted by applicable Law and existing contractual obligations of the Transferred Company, its Subsidiaries or their respective assets) in the assets listed in Section 5.9(c)(ii) of the Seller Disclosure Schedule (such first-priority perfected security interests securing the Genco Guaranty and the AERG Guaranty, collectively, the “Security Interests”). Such Security Interests shall remain in place until the later of (x) the end of the Specified Period and (y) the date on which Seller or its Affiliates have been released from all Post-Closing Credit Support (such date, the “Release

-59-

Date”); provided, however, that (I) in the event a written notice(s) of a claim(s) related to an Indemnification Payment has been given in accordance with Section 10.4(a) of this Agreement prior to the expiration of the Specified Period and such claim(s) has not been finally resolved prior to the Release Date, the Release Date automatically shall, solely with respect to the Indemnification Payment stated in such notice(s), be extended until such claim(s) is finally resolved or such Security Interest has been replaced by other credit support in a form reasonably acceptable to Seller, or (II) if the Transferred Company and/or any of its Subsidiaries file a petition for relief in a voluntary case, or a court enters an order for relief in an involuntary case, under the Bankruptcy Code on or prior to the Release Date (after taking into account any extension thereof pursuant to subclause I), the Release Date shall automatically extend until the earlier of (A) the entry of an Order granting relief under Section 362(d) of the Bankruptcy Code permitting Seller to foreclose on the assets subject to the Security Interests in respect of any amount owed to Seller or any of its Subsidiaries under any then-remaining Post-Closing Credit Support and (B) the release or discharge of the Security Interests pursuant to a final, non-appealable order of a court of competent jurisdiction closing the related bankruptcy case. Recourse to the Security Interests and claims against the Transferred Company or one of its Subsidiaries, as applicable, shall be limited to an amount equal to any Indemnification Payments for which Seller has not been repaid (including repayment pursuant to Section 5.9(b)) less any actual amounts previously offset under the Seller Offset Right. Seller agrees not to enforce any remedy in respect of the Security Interests until 10 Business Days have elapsed after a request by Seller, which has not been met, that any Indemnification Payments actually made be reimbursed to Seller. Subject to the foregoing limitations, in the event that Seller has a valid claim against IPH, the Transferred Company or one of its Subsidiaries, as applicable, in respect of a an Indemnification Payment, IPH shall make, or cause to be made, such payment promptly (and in any event no later than 10 Business Days following a request by Seller for payment); provided that, in the event IPH fails to make such payment within such 10-day period, Seller may, in its sole discretion and in addition to, and in no way in limitation of, its other rights and remedies herein, under applicable Law or contract, offset any payment obligation of Ameren Illinois Company, an Illinois corporation and wholly owned Subsidiary of Seller (“AIC” ), to the Transferred Company against any amount owed to Seller under this Section 5.9 until such time as Seller or AIC has offset an aggregate amount of $35,000,000 (the “Seller Offset Right”) (and IPH hereby agrees, promptly following Closing, at the request of Seller, to cause the Transferred Company and Marketing Company to enter into a cross-affiliate set-off agreement with Seller and AIC giving effect to such arrangement in a form reasonably acceptable to each of Seller and IPH). Notwithstanding anything in this Agreement to the contrary, Seller may not offset any payment obligation of AIC to the extent that such payment obligation is for the benefit of Genco or any Subsidiary of Genco (regardless of the identity of the payee of such payment obligation). Notwithstanding anything in this Agreement to the contrary, Seller may not offset any payment obligation of AIC to the extent that such payment obligation is for the benefit of Genco or any Subsidiary of Genco (regardless of the identity of the payee of such payment obligation).

(d) IPH shall at its sole expense use its commercially reasonable best efforts (and shall reasonably cooperate with Seller’s efforts) to cause IPH or the Transferred Company or its or their respective Subsidiaries to be substituted in all respects for Seller and its Affiliates, and for Seller and its Affiliates to be released, effective as soon as possible after the Specified Period with respect to the Post-Closing Credit Support, in respect of all obligations of Seller and any of its Affiliates under the Post-Closing Credit Support. In furtherance and not in limitation of the preceding sentence, (i) at Seller’s request IPH will use its commercially reasonable best efforts to, and will cause its Affiliates (including the Transferred Company or its Subsidiaries) to use their commercially reasonable best efforts to, assign or cause to be assigned, effective as of the end of the Specified Period, any agreement underlying any Post-Closing Credit Support to IPH or a Subsidiary of IPH to give effect to the provisions of the preceding sentence and (ii) at Seller’s request, IPH will offer (and provide, if accepted) a sufficient amount of letters of credit from financial institutions reasonably acceptable to Seller to the counterparties or other related parties with respect to the Post-Closing Credit Support (not released prior to the end of the Specified Period to enable Seller and its Affiliates to terminate such Post-Closing Credit Support without liability or otherwise be released or replaced in connection therewith. For any Post-Closing Credit Support for which IPH or the Transferred Company or its or their respective Subsidiaries, as applicable, is not substituted in all respects for Seller and its Affiliates (and for which Seller and its Affiliates are not released) effective as of the end of the Specified Period, IPH shall continue to use its commercially reasonable best efforts and shall cause the Transferred Company and its Subsidiaries to use their commercially reasonable best efforts to effect such substitution and release as soon as possible after the end of the Specified Period.

(e) Subject to Section 5.9(a), from the date of this Agreement through Closing, Seller shall have the right to eliminate, terminate or set off (i) any of the Specified Financial Obligations and/or Credit Support (and/or the underlying physical and/or financial commodity products that are covered by such Credit Support at commercially reasonable market values) for calendar year 2016 or beyond; provided that IPH receives the positive fair market value of the positions held by the Transferred Company or any of its Subsidiaries as measured by a non-Affiliate counterparty pursuant to the terms of the underlying Contract (as such terms are in effect as of the date of this Agreement) in aggregate for such termination or set off and neither IPH, the Transferred Company nor any Subsidiary of the Transferred Company has an obligation to pay a positive net amount to counterparties to such Credit Support in connection with such termination or set off; (ii) any Credit Support related to Contracts for physical and/or financial commodity products that does not have any Specified Financial Obligations outstanding thereunder and (iii) any other Credit Support as long as such elimination, termination or set off does not cause, result in, or permit, with the giving of notice, the passage of time, or both during the Specified Period, the termination, amendment or other effect on any Specified Financial Obligations, provided however that Seller may not for the Specified Period eliminate Credit Support related to Contracts whose pricing is cost-based on Plant related costs or any capacity Contracts in existence at Closing. Notwithstanding the foregoing, until the end of the Specified Period, Seller shall not eliminate or terminate or set off any of the Specified

-61-

Financial Obligations under any Credit Support for calendar year 2014 or calendar year 2015 (or the underlying physical and/or financial commodity products that are covered by such Credit Support); provided, however, that Seller may eliminate, terminate or set off any such Credit Support but solely to the extent such termination, elimination or set off does not terminate, amend or otherwise have any effect whatsoever on the Specified Financial Obligations.

(f) During the Specified Period, promptly upon the request of IPH, the Transferred Company or any of its and their respective Subsidiaries, Seller shall provide such requesting Person the financial information relating to Seller or any Affiliate of Seller required by the terms of the Contracts subject to Post-Closing Credit Support.

Section 5.10 Insurance.

(a) From and after the Closing Date, the Transferred Company and its Subsidiaries shall cease to be insured by Seller or its Affiliates’ (other than the Transferred Company’s or its Subsidiaries’) insurance policies or by any of their self-insured programs, and shall have no access to any such insurance policies except as set forth in this Section 5.10.

(b) If, between the date of this Agreement and the Closing Date, there shall occur any physical damage to or destruction of any of the assets of the Transferred Company and its Subsidiaries (a “Casualty Loss”), then (i) if such Casualty Loss exceeds the deductible for any applicable casualty insurance, Seller shall promptly give notice to IPH thereof and of Seller’s estimate of the amount of insurance payable to Seller or its Affiliates in respect thereof, and (ii) Seller shall, and shall cause its Affiliates to, use all reasonable best efforts to collect amounts due (if any) under available insurance policies or programs in respect of any Casualty Loss of the Transferred Company or its Subsidiaries (any such amounts collected, “Insurance Proceeds”) and shall cause any such Insurance Proceeds to be contributed to the Transferred Company or its applicable Subsidiary that has suffered such Casualty Loss which may be used to repair or replace the Casualty Loss.

(c) Without limiting the rights of IPH and the IPH Indemnified Parties set forth elsewhere in this Agreement, after the Closing, Seller shall, and shall cause its Subsidiaries to, cooperate and use commercially reasonable efforts to permit IPH, the Transferred Company and any of their respective Subsidiaries to submit, pursue claims and recover proceeds relating to pre-Closing occurrences (whether or not known as of the Closing) under any of the occurrence-based policies issued at any time prior to the Closing under which the Business, the Transferred Company, any of its Subsidiaries or their respective assets were insured and Seller shall not, and shall not permit any of its Subsidiaries to release, commute, buy-back or otherwise eliminate coverage available to the Business, the Transferred Company, any of its Subsidiaries or their respective assets under any such policy.

(d) Seller shall maintain in effect for not less than six years after the Closing, by prepaid run-off or “tail coverage” endorsement, the coverage provided by directors’ and officers’ liability, the coverage currently provided for the Transferred Company for employment practices liability, and the fiduciary liability coverage currently provided for the Transferred Company’s plans under which the Transferred Company and its Subsidiaries are insured as of the Closing; provided that Seller may substitute prepaid policies of at least the same coverage containing terms and conditions that are no less advantageous to the Transferred Company and its Subsidiaries so long as such substitution does not result in gaps or lapses in coverage with respect to matters occurring prior to the Closing Date.

Section 5.11 Litigation Support. In the event and for so long as either party is prosecuting, contesting or defending any legal proceeding, Action, investigation, charge, claim, or demand by a third party in connection with (a) any transactions contemplated under this Agreement, or (b) any fact, situation, circumstance, status, condition, activity, practice, plan, occurrence, event, incident, action, failure to act, or transaction relating to, in connection with or arising from the Business or the Transferred Company or its Subsidiaries, the other party shall, and shall cause its Subsidiaries and controlled Affiliates (and its and their officers and employees) to, use commercially reasonable best efforts to cooperate in such prosecution, contest or defenses, including, without limitation, making available its personnel, and provide such testimony and access to its books and records as shall be reasonably necessary in connection with such prosecution, contest or defense, all at the sole cost and expense of the contesting or defending party (unless the contesting or defending party is entitled to indemnification therefor pursuant to Article X).

Parent may, to most effectively access the financing markets and for purposes of maintaining compliance with its reporting obligations under the Exchange Act and its obligations under the Securities Act, require the cooperation of Seller and its Subsidiaries under this Section 5.14 at any time and from time to time, and Seller shall use commercially reasonable efforts to assist in the preparation of, and shall, prior to the Closing Date, cause the AER Parties to use commercially reasonable efforts to assist in the preparation of, the information set forth in the definition of “Required Financial Information” as promptly as is reasonably practicable following the conclusion of the applicable reporting period.

IPH shall indemnify and hold harmless each of Seller 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 the performance of their respective obligations under this Section 5.14 , in each case other than (i) with respect to any information provided by or on behalf of Seller or any of its Subsidiaries pursuant to this Section 5.14 or (ii) to the extent any of such losses arise from the bad faith, gross negligence or willful misconduct of, or material breach of this Agreement by, the Seller or any of its Subsidiaries and their respective representatives. IPH shall, promptly upon request of Seller, reimburse Seller and its Subsidiaries for all reasonable and documented out-of-pocket costs and expenses incurred by Seller and its Subsidiaries (including those of their respective representatives) in connection with the cooperation required by this Section 5.14.

Section 5.15 Air Variance. Each of the parties agrees to use its reasonable best efforts to take, or cause to be taken, all actions, to file and prepare, or cause to be filed and prepared, all documents and to do, or cause to be done, all things necessary and proper to petition and obtain the IPCB Approval (including, for the avoidance of doubt, agreeing to the terms of the IPCB Approval, provided such terms are identical in all material respects as the terms set forth in the Air Variance as of the date of this Agreement as such terms apply to the Plants and no new material terms are imposed upon the Transferred Company or any of its Subsidiaries). From and after the Closing, all obligations in the Air Variance with respect to any Retained Plant shall remain the sole responsibility of Seller, and all obligations in the Air Variance with respect to the Transferred Companies, any of its Subsidiaries and the Plants will be the sole responsibility of IPH. From and after the Closing, Seller shall take no action and ensure that none of its Affiliates or any other Person acting on behalf of Seller or any of its Affiliates takes any action with respect to the Retained Plants that would be inconsistent with or in violation of the Air Variance. The parties agree that, within 45 days of the date of this Agreement, they shall file a joint petition, or such other filing as they deem appropriate, to the IPCB seeking the IPCB Approval, unless the parties mutually agree that such filing should be made at a later date.

Section 5.16 Bifurcation of Certain Contracts.

(a) The parties will use their commercially reasonable efforts to replace the agreements listed on Section 5.16 of the Seller Disclosure Schedule entered into jointly by, or for the benefit of, Seller or one of its Affiliates (other than the Transferred Company and its Subsidiaries), on the one hand, and the Transferred Company and its Subsidiaries, on the other hand (collectively, the “Existing Joint Contracts”) with new contracts pursuant to which each of Seller or its Affiliates (other than the Transferred Company and its Subsidiaries), on the one hand, and the Transferred Company and its Subsidiaries (it being understood that, to the extent requested by IPH, the parties shall use commercially reasonable efforts to ensure that each Subsidiary of the Transferred Company shall enter into a separate new contract), on the other hand, will have separate agreements with the relevant third party, which in any event shall provide that any obligations of the Transferred Company and its

-67-

Subsidiaries shall be on a several and not joint basis (the “Replacement Contracts”). With respect to each Existing Joint Contract, the Replacement Contracts entered into in replacement thereof will provide in the aggregate for the same terms in all material respects with respect to each entity as provided in such Existing Joint Contract. Notwithstanding the previous two sentences or anything else to the contrary contained in this Agreement, in connection with entering into any Replacement Contract (i) Seller shall be obligated to fulfill its obligations under Section 5.14 and (ii) in no event shall IPH or any of its Affiliates (including the Transferred Company and its Subsidiaries following the Closing) be required to pay or commit to pay to any counterparty to an Existing Joint Contract any cash or other consideration, make any commitment or incur any liability or release any claim or waive any right, or post any cash, letter of credit or other form of collateral, in excess of the express obligations of AER or any of its Subsidiaries in existence as of the date of this Agreement.

(b) If, notwithstanding the commercially reasonable efforts of the parties as required by Section 5.16(a), a Replacement Contract has not been entered into by the Closing, the relevant Existing Joint Contract will remain in place and IPH and Seller shall, if possible, use their respective commercially reasonable efforts to cause the parties to such Existing Joint Contract to enter into agreements among themselves (it being understood that IPH may elect to have each applicable Subsidiary of the Transferred Company enter into a separate agreement) (each, an “Allocation Agreement”) providing for the individual obligations of each of Seller and its Affiliates consistent with past practice with respect to such Existing Joint Contract. Each of the Allocation Agreements will provide that each of the parties thereto will indemnify the others for all losses or expenses arising from any failure of the indemnifying party to satisfy its obligations under the applicable Existing Joint Contract, as such obligations are severally but not jointly allocated pursuant to each Allocation Agreement.

No later than immediately prior to the Closing, Seller shall update Section 1.1(x) of the Seller Disclosure Schedule to reflect new hires and terminations of employment following the date hereof. IPH will offer or cause an Affiliate to offer employment to each individual who would be a Transferred Company Employee but for the fact that he or she was on long-term disability leave on the Closing Date and who is able to return to active employment within 180 days following the Closing Date (any such individual, a “Leave Employee”) on terms of employment substantially consistent with this Article VI. Such employment offer shall be extended not more than seven days after IPH is notified that such Leave Employee is able to return to active employment and shall be effective for seven days following its extension, and each such Leave Employee who accepts such offer and commences employment with IPH or its applicable Affiliate as of the effective date of such offer shall be treated for all purposes under this Agreement as a Transferred Company Employee effective as of the date of his or her commencement of employment with IPH or the applicable Affiliate. Seller shall cause each individual who would be a Transferred Company Employee but for the fact that he or she was on long-term disability leave on the Closing Date to continue to be eligible for disability benefits under the applicable

-75-

Benefit Plan as in effect as of the date hereof unless and until such individual ceases to be disabled within the meaning of the applicable Benefit Plan as in effect on the date hereof. Neither IPH nor its Affiliates shall be liable for any claims for long-term disability benefits that are incurred by or with respect to any Leave Employee on or before the date such Leave Employee commences employment with IPH or its Applicable Affiliate. Any Transferred Company Employee not covered by an Assumed CBA who is on sick leave (but not long-term disability leave) as of the Closing Date (a “Sick Leave Employee”) shall remain eligible for long-term disability insurance coverage with Seller and its Affiliates until the earlier of (i) the 90^th day following the Closing Date (or such later date determined by Seller in its discretion) and (ii) the date such Sick Leave Employee returns to active employment with the Transferred Company and its Affiliates or terminates employment with the Transferred Company and its Affiliates. In the event that such Sick Leave Employee does not return to active employment with the Transferred Company and its Affiliates within 89 days following the Closing Date, (i) IPH and its Affiliates shall cause the employment of such Sick Leave Employee to be terminated as of the 89^th day following the Closing Date, (ii) Seller and its Affiliates shall be solely liable (and shall cause IPH and its Affiliates not to be liable) for any claims for long-term disability benefits that are incurred by or with respect to such Sick Leave Employee, and (iii) Seller and its Affiliates shall indemnify IPH and its Affiliates for the cost of any sick leave and related benefits incurred by IPH and its Affiliates with respect to such Sick Leave Employee at a rate not in excess of the cost of benefits made available by IPH or its Affiliates to other similarly situated Transferred Company Employees.

(b) From and after the Closing Date, IPH shall cause the Transferred Company or its Subsidiaries to retain or assume, as applicable, and honor, (i) all Transferred Company Benefit Plans and all liabilities thereunder and (ii) all collective bargaining agreements in respect of Transferred Company Employees. IPH hereby acknowledges that Seller and its Affiliates are parties to the collective bargaining agreements identified on Section 6.1(b)(i) of the Seller Disclosure Schedule (the “Assumed CBAs”). IPH agrees as a condition of this transaction that it will cause the Transferred Company or its Subsidiaries to fully assume all terms and obligations of the Assumed CBAs immediately effective upon the Closing Date, that it shall cause the Transferred Company or its Subsidiaries to fully abide by the terms of the Assumed CBAs in accordance with Law during the remaining term of such agreements or as otherwise permitted by Law, and that it shall indemnify Seller with respect to any liabilities attributable to the Assumed CBAs following the Closing Date. For the avoidance of doubt, Seller shall remain liable for, and shall indemnify IPH with respect to, any liabilities attributable to the Assumed CBAs prior to the Closing (other than liabilities relating solely to the actions of IPH and its Affiliates); provided, however, that with respect to any grievance or arbitration attributable to the Assumed CBAs that may result in liability to Seller, IPH will timely consult with Seller regarding the status of such grievance or arbitration and will not resolve such grievance or arbitration without consent of Seller, which consent shall not be unreasonably withheld. For the avoidance of doubt, IPH and Seller agree that IPH may cause the Transferred Company or its Subsidiaries to exercise any of its rights under the Assumed CBAs, including the right to negotiate modifications to the terms

-76-

thereof. IPH agrees to cause the Transferred Company or its Subsidiaries to engage in any type of bargaining that is required of it under the Assumed CBAs and Law with any collective bargaining representative listed on Section 6.1(b)(ii) of the Seller Disclosure Schedule, from the Closing Date until such obligation is no longer required under the Assumed CBAs. Seller agrees to and shall cause each of its Affiliates to engage in any type of bargaining that is required of it under the Assumed CBAs and Law with any collective bargaining representative listed on Section 6.1(b)(ii) of the Seller Disclosure Schedule prior to the Closing Date and in connection with the consummation of the transactions contemplated in this Agreement.

(c) For a period of no less than one year following the Closing Date, IPH shall provide, or shall cause the Transferred Company or its Subsidiaries to provide, each Transferred Company Employee not covered by a collective bargaining agreement with a base rate of pay not less than that in effect with respect to the Transferred Company Employee immediately before the Closing Date and incentive compensation and employee benefits that, in the aggregate, are no less favorable than the incentive compensation and employee benefits provided to similarly situated employees of IPH and its Affiliates from time to time. Without limiting the generality of the foregoing, IPH shall provide each Transferred Company Employees not covered by a collective bargaining agreement who is involuntarily terminated without cause during the one year period following the Closing Date with severance pay and benefits continuation that is no less favorable, in the aggregate, than the severance pay and benefits continuation to which such Transferred Company Employee would have been entitled under the severance plan set forth on Section 6.1(c) of the Seller Disclosure Schedule, determined without regard to any discretion of Seller and its Affiliates thereunder to reduce such pay and benefits, and determined based on the base salary level as of immediately prior to the Closing Date (or any greater amount as required by the applicable severance plan) of the applicable Transferred Company Employee, subject to the execution, by such terminated employee, of a general release of claims in favor of such Transferred Company Employee’s employer and its affiliates; provided that this sentence shall have no application in respect of a Transferred Company Employee party to an individual agreement containing severance provisions, or to the extent application would result in the duplication of severance benefits.

(d) Seller shall cause the Transferred Company and its Subsidiaries to cooperate reasonably with any request from IPH made before the Closing Date that is intended to facilitate a determination by IPH or its Affiliates as to whether to amend or terminate any Transferred Company Benefit Plan.

(a) The participation by Transferred Company Employees in Seller Benefit Plans that are Welfare Plans shall continue until immediately prior to the Closing Date. Effective as of the Closing Date, IPH shall ensure commencement of coverage for each Transferred Company Employee who was a participant in the Welfare Plans of Seller and its Affiliates as of the Closing Date in Welfare Plans

-77-

maintained by IPH and its Affiliates (but the foregoing shall not require any minimum level or specific type of Welfare Benefit or Welfare Plan).

(b) Except as otherwise provided in this Article VI, (i) Seller and its Affiliates shall be solely liable for any claims for Welfare Benefits that are incurred by or with respect to any Transferred Company Employee and his or her beneficiaries or dependents under a Seller Benefit Plan on or before the Closing Date, and (ii) IPH shall be solely liable for any Welfare Benefits obligations, liabilities and claims that may arise, including those that are incurred but not reported, by or with respect to any Transferred Company Employee and his or her beneficiaries or dependents after the Closing Date. For purposes of the foregoing, the following claims and liabilities shall be deemed to be incurred as follows: (x) life, accidental death and dismemberment and business travel accident insurance benefits, upon the death, disability or accident giving rise to such benefits; (y) hospital-provided health, dental, prescription drug or other benefits, which become payable with respect to any hospital confinement, upon commencement of such confinement; and (z) medical, dental, and vision, when the services are rendered, the supplies are provided or prescribed medication is acquired by the participant, and not when the condition arose.

(c) With respect to the coverage of the Transferred Company Employees under IPH’s Welfare Plans, (i) each such employee’s service with Seller and its Affiliates shall be credited against any waiting period applicable to eligibility for enrollment of new employees under IPH’s Welfare Plans; (ii) limitations on benefits due to pre-existing conditions shall be waived for any Transferred Company Employee enrolled in any Welfare Plan maintained by Seller and its Affiliates as of the Closing Date to the extent that such limitations on benefits would have been waived under the corresponding Seller Group Health Plan; and (iii) any out-of-pocket annual maximums and deductibles taken into account under the Seller Group Health Plan for any Transferred Company Employee in the calendar year that contains the Closing Date shall be credited under IPH’s Welfare Plans for the same calendar year. With respect to aggregate lifetime maximum benefits available under IPH’s Welfare Plans, a Transferred Company Employee’s prior claim experience under any of the Welfare Plans that are Seller Benefit Plans will not be taken into account.

(d) Effective as of the Closing Date, IPH shall be responsible for, and shall assume all liability with respect to, providing the notices and making available the health care continuation coverage, all as required by Section 4980B of the Code, for all of the Transferred Company Employees and their respective covered dependents, whose qualifying events (as defined in Code Section 4980B) occur after the Closing Date.

(e) From and after the Closing Date, (i) IPH shall assume and honor, and shall cause the Transferred Company and its Subsidiaries to honor, all unused vacation and other paid time off days of the Transferred Company Employees that accrued prior to the Closing Date to the extent not cashed out by Seller or its Affiliates, and (ii) IPH shall sponsor a paid time off policy that applies to each Transferred Company Employee that takes into account service with Seller and its

-78-

Affiliates as provided in Section 6.4(a). Notwithstanding the foregoing, in the event that Seller or one of its Affiliates is required under applicable Law to make a payment in settlement of accrued vacation or paid time off of any Transferred Company Employee in connection with the transactions contemplated by this Agreement, IPH shall reimburse and hold harmless Seller and its Affiliates for such payment to the extent that, by reason of such payment by Seller or its Affiliates, IPH or its Affiliates are relieved from a liability they otherwise would have assumed pursuant to the immediately preceding sentence.

(f) Seller and IPH shall take all actions necessary or appropriate so that, effective as of the Closing Date, (i) the account balances (whether positive or negative) (the “Transferred Account Balances”) under the flexible spending component of the Ameren Cafeteria Plan (“Seller’s Flex Plan”) of the Transferred Company Employees who are participants in Seller’s Flex Plan (the “FSA Covered Employees”) shall be transferred to one or more comparable plans of IPH (collectively, the “IPH’s Flex Plan”); (ii) the elections, contribution levels and coverage levels of the FSA Covered Employees shall apply under IPH’s Flex Plan in the same manner as under Seller’s Flex Plan; and (iii) the FSA Covered Employees shall be reimbursed from IPH’s Flex Plan for claims which have been (A) incurred at any time during the plan year of Seller’s Flex Plan in which the Closing Date occurs and (B) submitted to IPH’s Flex Plan from and after the Closing Date, on the same basis and the same terms and conditions as under Seller’s Flex Plan. As soon as practicable after the Closing Date, and in any event within 10 Business Days after the amount of the Transferred Account Balances is determined, Seller shall pay IPH the net aggregate amount of the Transferred Account Balances, if such amount is positive, or IPH shall pay Seller the net aggregate amount of the Transferred Account Balances, if such amount is negative.

Section 6.3 Retirement Plans.

(a) As soon as practicable following the Closing Date, Seller and its Affiliates shall permit the account balances of the Transferred Company Employees in any tax-qualified defined contribution plans of Seller and its Affiliates to be distributed in accordance with the terms of such plans, and for not less than one year following the Closing Date IPH shall permit Transferred Company Employees to the extent still employed by IPH and its Affiliates (including the Transferred Company and its Subsidiaries) to rollover such distribution (including a rollover of outstanding participant loans not then in default) into a tax-qualified defined contribution plan maintained by IPH or its applicable Affiliate.

(b) The parties agree to the following terms with respect to treatment of Transferred Company Employees covered by an Assumed CBA who participate in the Ameren Retirement Plan (the “Union Pension Participants”):

(i) Without limiting the generality of Section 6.1(b), IPH shall, effective as of the Closing Date, establish or maintain a cash balance pension plan (the “IPH Cash Balance Plan”) and a related funding arrangement which are qualified and

-79-

tax-exempt under Sections 401(a) and 501(a), respectively, of the Code. The IPH Cash Balance Plan shall contain terms substantially identical to those of the Ameren Retirement Plan as is applicable to the Union Pension Participants as of the Closing Date. IPH will cause the IPH Cash Balance Plan to expressly provide that any Union Pension Participants will become participants in the IPH Cash Balance Plan as of the Closing Date.

(ii) Unless the IPH Cash Balance Plan and its related trust has received a favorable determination letter or opinion letter as to its qualification (and no circumstances have occurred, whether by action or failure to act, that could reasonably be expected to cause the loss of such qualification), IPH shall timely submit the IPH Cash Balance Plan to the Internal Revenue Service for a determination that the IPH Cash Balance Plan and its related trust are qualified and tax-exempt under Sections 401(a) and 501(a), respectively, of the Code. IPH shall, with respect to the participation of each Union Pension Participant, continue to maintain the IPH Cash Balance Plan on the terms contemplated by this Section 6.3(b) at least until expiration of the Assumed CBA applicable to such Union Pension Participant.

(c) Seller will retain responsibility for all liabilities under non-qualified deferred compensation plans that are Seller Benefit Plans in respect of pre-Closing service of Transferred Company Employees. As of no later than the Closing Date, Seller shall provide to IPH a list of all Transferred Company Employees who participated as of the date of such notice in any Benefit Plan that is a nonqualified deferred compensation plan within the meaning of Section 409A of the Code and IPH shall endeavor in good faith to notify Seller of the separation from service (within the meaning of Section 409A of the Code) of any such Transferred Company Employee from IPH or its Affiliates not later than 10 days following such separation, provided that neither IPH nor its Affiliates shall be liable to Seller, its Affiliates or any other Person by reason of a failure to provide such notice.

(d) Seller will retain responsibility for any liabilities under the Seller Retiree Medical Plan and provide coverage under the Seller Retiree Medical Plan in respect of any Transferred Company Employee who, as of the Closing Date (i) is receiving benefits (or otherwise eligible to receive benefits) or (ii) would be eligible to begin receiving benefits under such plans upon a termination of employment immediately prior to the Closing (with such coverage to commence upon any subsequent termination of employment with IPH upon or following the Closing).

Section 6.4 Miscellaneous Employee Issues.

(a) For all purposes of the employee benefit plans, practices, agreements or arrangements of IPH and its Affiliates providing benefits to any Transferred Company Employee after the Closing Date, each Transferred Company Employee shall be credited with all years of service for which such Transferred Company Employee was credited before the Closing Date under any similar employee benefit plans, practices, agreements or arrangements of Seller and its Affiliates to the extent they are eligible to participate in any such plans, practices, agreements or

-80-

arrangements (it being understood that each Transferred Company Employee shall be eligible to participate in all plans, practices, agreements and arrangements made available to similarly situated employees of IPH and its Affiliates), in any case except (subject to Section 6.3(b) for purposes of benefit accrual under any final average pay defined benefit plan) to the extent it would result in duplication of benefits.

(b) IPH agrees that provided Seller delivers to IPH within ten (10) Business Days following the Closing a true and correct list of all employment losses in the 90-day period immediately preceding the Closing, showing the name, department, facility, operating unit, date of termination and reason for termination of each such employee who suffered such an employment loss, if any obligations or requirements of the WARN Act are triggered by any actions taken or directed by IPH or the Transferred Company or its Subsidiaries on or after the Closing Date, it shall be solely responsible for all obligations, requirements and/or any liabilities that may result therefrom.

(c) Beginning at the Closing, all Transferred Company Employees shall be eligible for coverage under IPH’s workers’ compensation insurance.

(d) The provisions of this Article VI are solely for the benefit of the parties to this Agreement, and no employee or former employee of the Transferred Company or its Subsidiaries or any other individual associated therewith shall be regarded for any purpose as a third party beneficiary of this Agreement as a result of this Article VI. In no event shall any provision of this Article VI be deemed to create or amend any employee benefit plan or to create any enforceable rights under any such plan or to restrict the ability of the Transferred Company and its Affiliates from amending, modifying, supplementing or renegotiating any Benefit Plan, in accordance with the terms thereof and applicable Law.

ARTICLE VII

(b) Seller shall prepare an allocation of the Consideration (together with other relevant amounts), which shall be allocated among the assets of the Transferred Company, the assets of AERG and the Section 338(h)(10) Subsidiary as required pursuant to Sections 1060 and 338(h)(10) of the Code and the Treasury Regulations promulgated thereunder (the “Allocation”), and deliver such Allocation to IPH within 90 days following the Closing Date.

IPH and Seller shall use their reasonable best efforts to reach agreement on the disputed items or amounts. The Allocation, as prepared by Seller if no timely IPH objection has been given or as adjusted pursuant to any agreement between the parties (the “Final Allocation”) shall be final and binding on all parties.

IPH and Seller shall, or shall cause their relevant Affiliates to, timely file such Section 338(h)(10) Forms with the applicable taxing authorities. Seller and IPH agree that neither of them shall, or shall permit any of their Affiliates, to revoke the Section 338(h)(10) Elections following the filing of the Section 338(h)(10) Forms without the prior written consent of Seller or IPH, as the case may be.

(d) Each of IPH and Seller shall deliver to the other party at the Closing one or more duly executed IRS Forms 8023 that reflect the Section 338(h)(10) Elections.

Section 7.2 Tax Indemnity.

Section 7.4 Tax Contests.

(a) If any taxing authority asserts a Tax Claim with respect to the Transferred Company or any of its Subsidiaries, then the party to this Agreement first receiving notice of such Tax Claim promptly shall provide written notice thereof to the other party or parties to this Agreement; provided, however, that the failure of such party to give such prompt notice shall not relieve the other party of any of its obligations under this Article VII, except to the extent that the other party is actually

-85-

prejudiced thereby. Such notice shall include a copy of the relevant portion of any correspondence received from the taxing authority.

(b) Seller shall have the exclusive right to control, at its own expense, any Tax Proceeding relating to a Tax of the Transferred Company or any of its Subsidiaries for any taxable period that ends on or before the Closing Date; provided that Seller shall keep IPH reasonably informed with regard to such Tax Claim.

IPH shall pay to the Seller the amount of any Tax Benefit actually realized in cash by IPH or any of its Affiliates in connection with the incurrence of any Loss for which Seller has indemnified IPH pursuant to this Article VII or Article X. The amount of a Tax Benefit shall be calculated on a “with and without” basis, taking into account any Taxes imposed on any payments received from Seller under this Agreement and all other relevant facts.

Section 7.10 Transfer Taxes. Notwithstanding anything to the contrary in this Agreement, IPH and Seller shall each pay 50% of all sales, use, registration, transfer, documentary, stamp, value added or similar Taxes, fees and costs (collectively, “Transfer Taxes”) incurred in connection with the transactions contemplated by this Agreement (other than the Alternative Gas Plant Transaction). In addition, IPH shall prepare and submit to Seller for Seller’s approval (such approval not to be unreasonably withheld, conditioned or delayed), and thereafter IPH shall timely file all Tax Returns required to be filed with respect to such Transfer Taxes.

Section 7.11 Survival. The indemnification obligations contained in this Article VII shall survive the Closing Date until 90 days after the expiration of the applicable statutory periods of limitation (including any waivers or extensions thereof); provided, that the indemnification obligations of IPH for any Specified Tax-Related Claims shall survive indefinitely. The representations and warranties in Section 3.13 (other than the representations and warranties in Section 3.13(vii), (viii), (x), (xiii), (xv), (xvii), and (xviii)) shall not survive the Closing. The representations and warranties in Section 3.13(vii), (viii), (x), (xiii), (xv), (xvii), and (xviii) shall survive the Closing Date until 90 days after the expiration of the applicable statutory periods of limitation (including any waivers or extensions thereof).

Section 7.12 Exclusivity. Anything in this Agreement to the contrary notwithstanding, indemnification with respect to Tax matters and the procedures relating thereto shall be governed exclusively by this Article VII and the provisions of Article X shall not apply. For the avoidance of doubt, to the extent any term or provision of this Article VII is in conflict with any term or provision with respect to Tax matters contained in the Put Option Asset Purchase Agreement, the terms and provisions of this Article VII shall govern to the extent of such conflict.

Section 7.13 Tax Treatment of Payments. Seller and IPH agree that, except to the extent otherwise required pursuant to a Determination, all payments made pursuant to this Article VII or Article X shall be treated by the parties as an adjustment to the Consideration for Tax purposes; provided, however, that any such adjustment shall incorporate, reflect and be consistent with Section 7.1(b).

Section 7.14 Non-Foreign Certificate. At the Closing, Seller shall deliver to IPH a duly executed certificate of non-foreign status, substantially in the form specified in Treasury Regulation Section 1.1445-2(b)(2)(iv)(B), failing which IPH shall be entitled to deduct and withhold from any payment made at Closing any amounts it may be required to so deduct and withhold under Section 1445 of the Code.

-96-

Section 10.4 Indemnification Procedures.

(a) Any Person that may be entitled to be indemnified under this Agreement or the Transitional Services Agreement (the “Indemnified Party”), shall promptly notify the party liable for such indemnification (the “Indemnifying Party”) in writing of any pending or threatened claim or demand that the Indemnified Party has determined has given or would reasonably be expected to give rise to a right of indemnification under such agreement (including a pending or threatened claim or demand asserted by a third party (including a Governmental Entity) against the Indemnified Party, such claim being a “Third Party Claim”), describing in reasonable detail the facts and circumstances with respect to the subject matter of such claim or demand, and such notice shall be given within 15 days of such determination; provided, however, that the failure to provide such notice shall not release the Indemnifying Party from any of its obligations under this Article X except to the extent the Indemnifying Party is materially prejudiced by such failure, it being agreed that notices for claims in respect of a breach of a representation, warranty, covenant or agreement must be delivered prior to the expiration of any applicable survival period specified in Section 11.1 for such representation, warranty, covenant or agreement.

(b) Upon receipt of a notice of a claim for indemnity from an Indemnified Party pursuant to Section 10.4(a), the Indemnifying Party will be entitled to assume the defense and control of any Third Party Claim, but shall allow the Indemnified Party a reasonable opportunity to participate in the defense of such Third Party Claim with its own counsel and at its own expense; provided, however, that, if (i) the Indemnifying Party and the Indemnified Party are both named parties to the proceedings and, in the reasonable opinion of counsel, there exists a conflict of interest or a conflict of interest is likely to exist that would make it inappropriate for the same counsel to represent both the Indemnified Party and the Indemnifying Party or (ii) within 30 days after notice of the institution of such Third Party Claim, the Indemnifying Party has not elected to undertake, conduct and control, through counsel of its own choosing, the settlement or defense thereof, then the Indemnified Party shall be entitled to retain its own counsel, at the expense of the Indemnifying Party; provided that the Indemnifying Party shall not be obligated to pay the reasonable fees and expenses of more than one separate counsel for all Indemnified Parties, taken together (as well as a single local counsel in each relevant jurisdiction, if applicable). If the Indemnifying Party does not assume the defense and control of any Third Party Claim, it may nonetheless participate in the defense of such Third Party Claim with its own counsel and at its own expense. If the Indemnifying Party shall assume the defense and control of a Third Party Claim, the Indemnifying Party shall select counsel, contractors and consultants of recognized standing and competence after consultation with the Indemnified Party and shall use commercially reasonable efforts in the defense or settlement of such Third Party Claim. Seller or IPH, as the case may be, shall, and shall cause each of its Affiliates, each of their respective directors, officers, employees, agents and representatives, and each of the heirs, executors, successors and assigns of any of the foregoing to, reasonably cooperate with the Indemnifying Party in the defense of any Third Party Claim or the Indemnified Party if it is conducting the defense of any Third Party Claim, including by furnishing books

-97-

and records, personnel and witnesses, as appropriate for any defense of such Third Party Claim, in each case at no cost to the party conducting such defense other than reasonable out-of-pocket costs and expenses; provided, however, that such access shall not require the Indemnified Party to disclose any information the disclosure of which would, in the reasonable judgment of the Indemnified Party, result in the loss of any existing attorney-client privilege with respect to such information or violate any applicable Law to which the Indemnified Party is subject. If the Indemnifying Party shall have assumed the defense and control of a Third Party Claim, it shall be authorized to consent to a settlement of, or the entry of any judgment arising from, any Third Party Claim, in its sole discretion and without the consent of any Indemnified Party; provided that the Indemnifying Party shall (A) pay or cause to be paid all amounts in such settlement or judgment (other than solely with respect to the Deductible, to the extent such liabilities would constitute Losses to which the Deductible would be applicable in accordance with the applicable provisions of Section 10.1(b) or Section 10.2(b)), (B) not encumber any of the assets of any Indemnified Party or agree to any restriction or condition that would apply to or adversely affect any Indemnified Party or the conduct of any Indemnified Party’s business (including (x) the imposition of any consent order, injunction or decree that would restrict the future activity or conduct of the Indemnified Party or any of its Affiliates or (y) any finding or admission of a violation of Law or violation of the rights of any Person by the Indemnified Party or any of its Affiliates) and (C) obtain, as a condition of any settlement or other resolution, a complete release of any Indemnified Party potentially affected by such Third Party Claim. The Indemnified Party will not consent to the entry of any judgment or enter into any settlement or compromise with respect to a Third Party Claim without the prior written consent of the Indemnifying Party so long as the Indemnifying Party is in good faith defending such claim. Notwithstanding the foregoing, the Indemnified Party shall have the right to control, pay or settle any Third Party Claim which the Indemnifying Party shall have undertaken to defend so long as the Indemnified Party shall also waive any right to indemnification therefor by the Indemnifying Party.

(c) If the Indemnified Party receives any payment from an Indemnifying Party in respect of any Losses pursuant to Section 10.1 or Section 10.2 and the Indemnified Party could have recovered all or a part of such Losses from a third party (a “Potential Contributor”) based on the underlying claim asserted against the Indemnifying Party, the Indemnified Party shall assign such of its rights to proceed against the Potential Contributor as are necessary to permit the Indemnifying Party to recover from the Potential Contributor the amount of such payment.

(d) Notwithstanding anything to the contrary in this Section 10.4, in the event of a Third Party Claim related to CCB Liabilities, Seller shall undertake, conduct and control, through counsel of its own choosing, the settlement, defense, cleanup or remediation thereof; provided that (i) in the event such Third Party Claim would reasonably be expected to result solely in indemnification obligations of IPH with respect to Assumed CCB Liabilities, IPH shall have the right to either (A) undertake, conduct and control, through counsel of its own choosing, the settlement or defense thereof or agree to implement any cleanup or remediation thereof or (B) have

-98-

Seller undertake, conduct and control such defense, cleanup or remediation at the expense of IPH (provided that in such scenario, Seller shall keep IPH reasonably informed of the progress of the defense of such Third Party Claim or the implementation of any settlement, cleanup or remediation thereof and in no event shall Seller be entitled to settle such Third Party Claim without IPH’s consent) and (ii) in the event such Third Party Claims could reasonably be expected to result in indemnification obligations to be shared by Seller and IPH with respect to Retained CCB and Assumed CCB Liabilities, respectively, (A) counsel selected by Seller shall be reasonably acceptable to IPH, (B) Seller shall keep IPH reasonably informed of the progress of the defense of such Third Party Claim or the implementation of any settlement, cleanup or remediation thereof, (C) Seller shall consult in good faith with IPH and, to the extent not prohibited, give IPH the opportunity to attend any substantive meeting or discussion with the counterparty to the Third Party Claim, and (D) Seller shall not enter into any settlements or agree to perform any cleanup or remediation without the prior written approval of the IPH.

Section 10.5 Exclusive Remedies. Except with respect to the matters covered by Section 2.4, clauses (b) and (c) of Section 5.9, Section 5.14 or Section 11.11, with respect to any matter relating to Taxes (which shall be governed exclusively by Article VII) and in the case of fraud, Seller and IPH acknowledge and agree that, following the Closing, the indemnification provisions of Section 10.1 and Section 10.2 shall be the sole and exclusive remedies of Seller and IPH, respectively, for any Losses (including any Losses from claims for breach of contract, warranty, tortious conduct (including negligence) or otherwise and whether predicated on common law, statute, strict liability, or otherwise) that each party may at any time suffer or incur, or become subject to, as a result of, or in connection with, any breach of any representation or warranty in this Agreement by the other party, or any failure by the other party to perform or comply with any covenant or agreement that, by its terms, was to have been performed, or complied with, by such other party prior to the Closing. Subject to, and without limiting the generality of the foregoing, the parties hereto hereby irrevocably waive any right of rescission they may otherwise have or to which they may become entitled.

Section 10.6 Additional Indemnification Provisions. With respect to each indemnification obligation contained in this Agreement or the Transitional Services Agreement or any other document executed in connection herewith (a) all Losses shall be net of any third-party insurance proceeds (after deduction of related costs and expenses) that have been actually recovered by the Indemnified Party in connection with the facts giving rise to the right of indemnification, and the Indemnified Party shall use its commercially reasonable efforts to seek full recovery under all insurance provisions covering such Loss to the same extent as it would if such Loss were not subject to indemnification hereunder; and (b) in no event shall the Indemnifying Party have liability to the Indemnified Party for any consequential, incidental, indirect, special, remote, speculative or punitive damages or similar damages or lost profits damages (except in each case in this clause (b) to the extent such types of damages constitute Losses to a third party as a result of any claim).

Section 10.7 Mitigation. Each of the parties agrees to use its commercially reasonable efforts to mitigate its respective Losses upon and after becoming aware of any event

-99-

or condition that would reasonably be expected to give rise to any Losses that are indemnifiable hereunder.

(b) For the purposes of this Agreement, (i) words in the singular shall be held to include the plural and vice versa as the context requires; (ii) the terms

-100-

Section 11.4 Governing Law; Jurisdiction and Forum; WAIVER OF JURY TRIAL .

(a) This Agreement and all controversies arising out of or relating to this Agreement shall be governed by and construed in accordance with the Laws of the State of Delaware applicable to contracts executed and to be performed wholly within such State and without reference to the choice-of-law principles that would result in the application of the laws of a different jurisdiction.

(b) Each party to this Agreement irrevocably submits to the exclusive jurisdiction of the Court of Chancery of the State of Delaware, or to the

-101-

extent such Court does not have subject matter jurisdiction, the Superior Court of the State of Delaware or any federal court in the State of Delaware, with respect to any Action arising out of or relating to this Agreement, and hereby irrevocably agrees that all claims in respect of such Action may be heard and determined in such Delaware state or federal courts. Each party to this Agreement hereby irrevocably waives, to the fullest extent that it may effectively do so, the defense of an inconvenient forum to the maintenance of such Action. The parties further agree, to the extent permitted by Law, that final and unappealable judgment against any of them in any Action 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.

(c) EACH PARTY TO THIS AGREEMENT WAIVES TRIAL BY JURY IN ANY ACTION, PROCEEDING OR COUNTERCLAIM BROUGHT BY ANY OF THEM AGAINST THE OTHER ARISING OUT OF OR IN ANY WAY CONNECTED WITH THIS AGREEMENT, OR ANY OTHER AGREEMENTS EXECUTED IN CONNECTION HEREWITH OR THE ADMINISTRATION THEREOF OR ANY OF THE TRANSACTIONS CONTEMPLATED HEREIN OR THEREIN. NO PARTY TO THIS AGREEMENT SHALL SEEK A JURY TRIAL IN ANY LAWSUIT, PROCEEDING, COUNTERCLAIM OR ANY OTHER LITIGATION PROCEDURE BASED UPON, OR ARISING OUT OF, THIS AGREEMENT OR ANY RELATED INSTRUMENTS OR THE RELATIONSHIP BETWEEN THE PARTIES. NO PARTY WILL SEEK TO CONSOLIDATE ANY SUCH ACTION IN WHICH A JURY TRIAL HAS BEEN WAIVED WITH ANY OTHER ACTION IN WHICH A JURY TRIAL CANNOT BE OR HAS NOT BEEN WAIVED. EACH PARTY TO THIS AGREEMENT CERTIFIES THAT IT HAS BEEN INDUCED TO ENTER INTO THIS AGREEMENT OR INSTRUMENT BY, AMONG OTHER THINGS, THE MUTUAL WAIVERS AND CERTIFICATIONS SET FORTH ABOVE IN THIS SECTION 11.4. NO PARTY HAS IN ANY WAY AGREED WITH OR REPRESENTED TO ANY OTHER PARTY THAT THE PROVISIONS OF THIS SECTION WILL NOT BE FULLY ENFORCED IN ALL INSTANCES.

Section 11.8 Successors and Assigns. This Agreement shall be binding upon and inure to the benefit of the parties to this Agreement and their respective successors and assigns; provided, however, that no party to this Agreement may directly or indirectly assign any or all of its rights or delegate any or all of its obligations under this Agreement without the express prior written consent of each other party to this Agreement, except that Seller may assign its benefits under this Agreement to any Affiliate of Seller (but no such assignment of benefits shall relieve Seller of its obligations under this Agreement). Any attempted assignment in violation of this Section 11.8 shall be void.

Section 11.9 Amendments and Waivers. This Agreement may not be modified or amended except by an instrument or instruments in writing signed by the party against whom enforcement of any such modification or amendment is sought. Either party to this Agreement may, only by an instrument in writing, waive compliance by the other parties to this Agreement with any term or provision of this Agreement with which such other parties to this Agreement are obligated to perform or comply. The waiver by any party to this Agreement of a breach of any term or provision of this Agreement shall not be construed as a waiver of any subsequent breach.

Section 11.10 Severability. If any term, provision, covenant or restriction of this Agreement is held by a court of competent jurisdiction or other authority to be invalid, void or unenforceable, the remainder of the terms, provisions, covenants and restrictions of this Agreement shall remain in full force and effect and shall in no way be affected, impaired or invalidated so long as the economic or legal substance of the transactions contemplated hereby is not affected in any manner materially adverse to any party hereto. Upon such a determination, 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 a mutually acceptable manner in order that the transactions contemplated hereby be consummated as originally contemplated to the fullest extent possible.

Section 11.11 Specific Performance; Remedies. The parties hereby acknowledge and agree that irreparable injury for which monetary damages, even if available, would not be an adequate remedy would occur in the event that any party fails to perform its agreements and covenants hereunder, including its failure to take all actions necessary to consummate the transactions contemplated by this Agreement in accordance with the terms of this Agreement, and that the parties shall be entitled to specific performance in such event (in addition to any other remedy at Law or in equity), and to thereafter cause the Transaction and the other transactions contemplated by this Agreement to be consummated on the terms and subject to the conditions set forth herein. Each of the parties hereto hereby waives (i) any defenses in any action for specific performance that a remedy at Law would be adequate and (ii) any requirement under any Law to post a bond or other security as a prerequisite to obtaining equitable relief. If any party brings any action to enforce specifically the performance of the terms and provisions hereof by any other party, the Outside Date shall automatically be extended by (x) the amount of time during which such action is pending, plus 20 Business Days or (y) such other time period established by the court presiding over such action. The parties agree that, if a court of competent jurisdiction has declined to specifically enforce the obligation of either IPH or Seller,

-104-

as applicable, to consummate the transactions contemplated by this Agreement (including, without limitation, Seller’s obligations under Section 5.24) pursuant to a claim for specific performance brought against either IPH or Seller, as applicable, pursuant to this Section 11.11 but has found that a IPH Termination Fee Event or a Seller Termination Fee Event has occurred, no later than 2 Business Days after such determination, IPH shall pay to Seller or Seller shall pay to IPH, as applicable, the Termination Fee (by wire transfer in immediately available funds to an account specified by Purchase or Seller, as applicable). The parties hereto acknowledge that the Termination Fee shall not constitute a penalty but is liquidated damages, in a reasonable amount that will compensate the party receiving such funds in the form of a termination fee in the circumstances in which the Termination Fee is payable for the efforts and resources expended and opportunities foregone while negotiating this Agreement and in reliance on this Agreement and on the expectation of the consummation of the transactions contemplated by this Agreement, which amount would otherwise be impossible to calculate with precision.

Section 11.12 No Admission. Nothing herein shall be deemed an admission by Seller or any of its respective Affiliates, in any action or proceeding by or on behalf of a third party, that such third party is or is not in breach or violation of, or in default in, the performance or observance of any term or provisions of any contract.

Section 11.13 Counterparts. This Agreement may be executed in two or more counterparts, all of which shall be considered one and the same agreement, and shall become effective when one or more counterparts have been signed by each of the parties and delivered to the other parties.

Section 11.14 No Recourse. This Agreement may only be enforced against, and any Action based upon, arising out of, or related to this Agreement, or the negotiation, execution or performance of this Agreement, may only be brought against, the entities that are expressly named as parties hereto and then only with respect to the specific obligations set forth herein with respect to such party.

IN WITNESS WHEREOF, this Agreement has been signed by or on behalf of each of the parties as of the day first above written.

Prior to the Closing, Seller shall effect (or cause to be effected) the following reorganization steps (the “Pre-Closing Reorganization”):

1. Seller contributes, assigns, conveys and transfers all of the limited liability interests in DormantCo to AER.

2. AER forms New AER as a limited liability company under the laws of Delaware, an entity disregarded as separate from its owner for U.S. federal income tax purposes under Treasury Regulation Section ###-###-####-3(b).

3. After receipt of the Pre-Closing FERC Approval, AER contributes, assigns, conveys and transfers all of its assets and liabilities (other than (a) any outstanding debt obligations of AER to any member of the Seller Group, (b) the FutureGen Agreements and (c) all the issued and outstanding equity interests in Medina Valley) to New AER.

4. AERG merges with and into DormantCo with DormantCo as the surviving entity, which shall be renamed as determined by Seller (“New AERG”).

It is understood and agreed by IPH and Seller that in no event shall Seller be obligated to effect the Pre-Closing Reorganization unless and until all of the conditions set forth in Article VIII, including receipt of the Pre-Closing FERC Approval, have been satisfied or waived (other than those conditions that by their nature are to be satisfied or waived at the Closing).
