ARTICLE 1

PURCHASE AND SALE OF DESIGNATED INTEREST

1.1 Purchase and Sale of Designated Interest. Upon the terms and subject to the conditions of this Agreement, at the Designated Interest Closing, Purchaser agrees to purchase from Seller, and Seller agrees to sell to Purchaser, the Designated Interest for $4,500,000,000 (the “Purchase Price”), as adjusted pursuant to Section 1.4.

1.2 Designated Interest Closing. The closing of the purchase and sale of the Designated Interest (the “Designated Interest Closing”) shall take place at 10:00 a.m., New York City time, at the offices of Skadden, Arps, Slate, Xxxxxxx & Xxxx LLP, 0 Xxxxx Xxxxxx, Xxx Xxxx, Xxx Xxxx, 00000 on the fifth (5th) Business Day immediately following the date on which the last of the conditions contained in Article 7 is satisfied or, to the extent permitted hereby, waived (other than those conditions that by their nature are to be satisfied at the Designated Interest Closing, but subject to the satisfaction, or to the extent permitted hereby, waiver of such conditions), or at such other time or on such other date or at such other place as Purchaser and Seller may mutually determine (the “Designated Interest Closing Date”).

1.3 Deliveries at the Designated Interest Closing. At the Designated Interest Closing:

(a) Purchaser shall (i) pay to Seller in cash the Estimated Cash Purchase Price by wire transfer in immediately available funds to an account specified in writing by Seller to Purchaser and (ii) surrender the Series B Preferred to Seller, it being understood that the $1,000,000,000 in principal amount of Purchaser’s investment in the Series B Preferred together with any Accrued Dividends as of the Designated Interest Closing Date shall be credited in full against the Purchase Price;

(b) Seller shall deliver to Purchaser a duly and validly executed assignment of membership interests in the form attached hereto as Exhibit D (the “Assignment of

Membership Interests”), transferring ownership of the Designated Interest to Purchaser, free and clear of all Encumbrances, and otherwise sufficient to vest in Purchaser good title to the Designated Interest;

(c) Seller shall deliver to Purchaser (i) copies, certified by the Secretary or any Assistant Secretary of Seller and the Company, of resolutions authorizing the execution and delivery of this Agreement and all of the Ancillary Documents, and the consummation of the transactions contemplated hereby and thereby and (ii) a certificate of good standing with respect to each of Seller and the Company, issued by the Department of Assessments and Taxation of the State of Maryland;

(d) Purchaser shall deliver to Seller (i) copies, certified by the Secretary or any Assistant Secretary of Purchaser, of resolutions authorizing the execution and delivery of this Agreement and all of the Ancillary Documents, and the consummation of the transactions contemplated hereby and thereby and (ii) a certificate of good standing with respect to Purchaser, issued by the Secretary of State of the State of Delaware;

(e) the Operating Agreement shall be duly executed and delivered by each of the Parties; and

(f) each Party shall deliver the other documents and agreements required to be delivered by it pursuant to Article 7.

1.4 Purchase Price Adjustments.

(a) Not later than ten (10) Business Days prior to the Designated Interest Closing Date, Seller shall, with the cooperation of the Company, prepare and furnish to Purchaser a statement of its good faith best estimate (including the work papers used to prepare such estimate) of the amount (the “Estimated Cash Purchase Price”) consisting of (i) the Purchase Price, (ii) decreased by $1,000,000,000 plus the estimated Accrued Dividends as of the Designated Interest Closing Date, (iii) decreased by one-half of the estimated Indebtedness of the Company and its Subsidiaries as of the Designated Interest Closing Date in an amount not to exceed the Indebtedness Cap, (iv) increased by one-half of the estimated amount of Cash and Cash Equivalents of the Company and its Subsidiaries as of the Designated Interest Closing Date, and (v) decreased by the estimated Bridge Facility Repayment Amount, if any. The statement shall be prepared using the same accounting principles, policies and methods as Seller has historically used in connection with the calculation of the items reflected on such statement; provided, that in no event shall any amount included within any single adjustment be included within any other adjustment in order to ensure that there is no double-counting of any amount. Within five (5) Business Days after the delivery of such statement by Seller to Purchaser, Purchaser may object in good faith to any portion of the Estimated Cash Purchase Price in writing. If Purchaser so objects, the Parties shall attempt to resolve their differences by negotiation, and the Estimated Purchase Price shall be adjusted solely by the amount of any adjustments agreed by the Parties. Any disputed portion that has not been agreed by the Parties shall be resolved in accordance with the provisions of Section 1.4(b) and paid as part of any post-Designated Interest Closing adjustment to the extent required by Section 1.4(c). The final version

of the statement provided for pursuant to this Section 1.4(a) is referred to herein as the “Estimated Cash Purchase Price Statement.”

(b) As promptly as practical, but in no event more than sixty (60) days after the Designated Interest Closing, Purchaser shall, with the cooperation of the Company, prepare and deliver to Seller a draft of a statement prepared in good faith setting forth its calculation of the Final Cash Purchase Price (the “Proposed Final Cash Purchase Price Statement”) which shall show, as of the Designated Interest Closing Date, the actual Accrued Dividends, the actual Indebtedness of the Company and its Subsidiaries as of the Designated Interest Closing Date but not to exceed the Indebtedness Cap, the actual Cash and Cash Equivalents of the Company and its Subsidiaries, and the actual Bridge Facility Repayment Amount, if any. The Proposed Final Cash Purchase Price Statement shall be prepared using the same accounting principles, policies and methods as Seller has historically used in connection with the calculation of the items reflected on such statement and as were used in preparing the Estimated Cash Purchase Price Statement. During the thirty (30) day period following the delivery by Purchaser of the Proposed Final Cash Purchase Price Statement, Seller and its auditors may review such statement and the working papers of the Company’s auditors relating to the Proposed Final Purchase Price Statement and shall have such access to Purchaser’s and the Company’s personnel as may be reasonably necessary to permit Seller and its auditors to review in detail the manner in which the Proposed Final Purchase Price Statement was prepared. Purchaser and Seller shall and shall cause the Company, as well as their respective advisors, to cooperate with one another in facilitating the preparation of the Proposed Final Cash Purchase Price Statement and its review. Upon completion of such review, Seller shall give any comments or objections it has with respect to the Proposed Final Cash Purchase Price Statement to Purchaser in writing within such thirty (30) day period (the “Objection Letter”). Purchaser and Seller shall attempt in good faith to resolve any differences and issues as set forth in the Objection Letter. If no Objection Letter is delivered or the matters set forth in the Objection Letter are so resolved, then the Proposed Final Cash Purchase Price Statement, as adjusted for any changes as are agreed upon by Seller and Purchaser, shall be final and binding upon Seller and Purchaser and shall constitute the final cash purchase price (the “Final Cash Purchase Price”). If the matters raised by Seller in the Objection Letter cannot be resolved between Purchaser and Seller within ten (10) days of the date of the Objection Letter, the question or questions in dispute shall then be promptly submitted to an accounting firm of recognized standing mutually agreeable to Seller and Purchaser (other than Seller’s auditors and Purchaser’s auditors), the decision of which as to such question or questions in dispute shall be final and binding upon Seller and Purchaser and the determination of the purchase price pursuant thereto shall be considered to be the Final Cash Purchase Price. The accounting firm shall be instructed to resolve solely the question or questions in dispute within thirty (30) days of submission. Each of Purchaser and Seller shall cooperate with and assist any independent accounting firm to determine the Final Cash Purchase Price, including by making available and granting reasonable access to records and employees.

(c) In the event the Final Cash Purchase Price is greater than the Estimated Cash Purchase Price paid by Purchaser at the Designated Interest Closing, Purchaser shall promptly (within five (5) Business Days of the determination of the Final Cash Purchase Price) pay to Seller an amount equal to the difference between the Final Cash Purchase Price and the Estimated Cash Purchase Price. In the event the Final Cash Purchase Price is less than the

Estimated Cash Purchase Price paid by Purchaser at the Designated Interest Closing, Seller shall promptly (within five (5) Business Days of the determination of the Final Cash Purchase Price) pay to Purchaser an amount equal to the difference between the Estimated Cash Purchase Price and the Final Cash Purchase Price.

(d) The fees of Purchaser’s and the Company’s auditors incurred in connection with the preparation of the Proposed Final Cash Purchase Price Statement shall be borne by Purchaser, and the fees of Seller’s and the Company’s auditors incurred in connection with their review of the Proposed Final Cash Purchase Price Statement shall be borne by Seller. The fees of any independent accounting firm appointed pursuant to this Section 1.4(d) shall be borne by Seller and Purchaser in proportion to the amounts by which their proposals differed from the independent accounting firm’s final determination.

1.5 Tax Withholding. Purchaser shall be entitled to deduct and withhold from the Purchase Price and the Exercise Price payable hereunder, or other payment otherwise payable pursuant to this Agreement, the amounts required to be deducted and withheld under the Code, or any provision of any U.S. federal, state, local or non-U.S. Tax law. Any amounts so withheld shall be paid over to the appropriate Taxing Authority. To the extent that amounts are so deducted and withheld, such deducted and withheld amounts shall be treated for all purposes of this Agreement as having been paid to Seller.

1.6 Alternative Structure. Notwithstanding any other provisions of this Agreement, prior to the Designated Interest Closing, the Parties shall use their respective reasonable best efforts to revise the structure of the sale of the Designated Interest (which may include the capitalization and operation of the Company after the Designated Interest Closing) (as revised, the “Revised Transaction”) in such a manner as to achieve improved economic efficiencies for the Parties as a result of completing the sale of the Designated Interest and subsequently owning and operating the Company. A Revised Transaction (i) shall not materially delay or jeopardize receipt of any required regulatory approvals or other consents and approvals relating to the consummation of the transactions contemplated by this Agreement or the Ancillary Documents; and (ii) shall result in Purchaser effectively acquiring a 49.99% interest in the Nuclear Business. The net present value of any U.S. Tax savings that are expected to be realized by Purchaser and Seller, directly or indirectly, as a result of a Revised Transaction (in comparison to the U.S. Tax consequences under this Agreement before such revision and taking into account for all purposes the net present value of future Tax cash flows) shall be shared in proportion to the respective ownership interest of Seller and Purchaser in the Company (after giving effect to the Designated Interest Closing) through structuring and other value delivery methods; provided however, that in no event will the sharing of any U.S. Tax Savings consist of the delivery or issuance of equity interests which result in Seller owning less than 50.01% of the Nuclear Business or Purchaser owning less than 49.99% of the Nuclear Business and provided further that in no event will this Section 1.6 be interpreted as to require either Party to make a cash payment to the other Party as a means of achieving the sharing of U.S. Tax savings. If Purchaser and Seller cannot agree on a particular Revised Transaction at least 3 months prior to the anticipated Designated Interest Closing Date, the Parties shall submit the matter for mediation. Each Party will pay an equal share of the costs associated with any such mediation. If Purchaser and Seller cannot agree on the amount of the U.S. Tax savings or the manner of

effectuating the sharing of U.S. Tax savings, then such disputes between them shall be subject to the dispute resolution provisions of Section 6.7(h) of this Agreement in their entirety.

ARTICLE 2

PUT OPTION

2.1 Grant. In consideration of the agreement of Seller to sell, and Purchaser to purchase, the Designated Interest, upon the terms and subject to the conditions of this Agreement, Purchaser hereby grants to Seller an irrevocable right to sell to Purchaser (the “Put Option”), and Purchaser shall have the obligation to purchase from Seller all, but not less than all, of Seller’s ownership interest in each of the Generation Assets.

2.2 Exercise Mechanics; Exercise Price.

(a) Seller may exercise the Put Option with regard to a particular Generation Asset or multiple Generation Assets by giving notice thereof from time to time to Purchaser (an “Exercise Notice”) at any time during the period (i) commencing on the date hereof, and (ii) ending upon the earlier of (x) December 31, 2010, or (y) any termination of this Agreement pursuant to Section 8.1(c) (the “Exercise Period”), subject to the satisfaction or waiver of the conditions precedent thereto set forth in Section 2.5. Each Exercise Notice shall specifically identify the Generation Asset or Generation Assets with respect to which Seller is exercising the Put Option. Under no circumstances shall the aggregate Exercise Price for all Generation Assets with respect to which Exercise Notices have been delivered under this Section 2.2 exceed $2,000,000,000 and Seller shall have no right to deliver an Exercise Notice with respect to any Generation Asset that has an Exercise Price which when added to the Exercise Prices of the Generation Assets for which Exercise Notices have been previously delivered to Purchaser would exceed $2,000,000,000.

(b) Exhibit B sets forth a list of the Generation Assets and the respective prices payable by Purchaser upon the closing of an exercise of the Put Option with respect to a particular Generation Asset (the “Exercise Price”). Seller may provide an Exercise Notice for a Generation Asset to the extent and only to the extent each of the conditions precedent to the exercise of the Put Option set forth in Section 2.5 with respect to such Generation Asset have been satisfied, or waived in writing by Purchaser, prior to the delivery of such Exercise Notice.

(i) The items set forth on Section 2.2(c)(i) of the Seller Disclosure Schedule are referred to herein as “Seller Required Put Consents.” Notwithstanding anything to the contrary in this Agreement, Seller shall deliver Section 2.2(c)(i) of the Disclosure Schedule in accordance with the terms of Section 2.9(c) of this Agreement. The items to be listed on Section 2.2(c)(i) of the Disclosure Schedule are those items that Seller must obtain such that the exercise of the Put Option with respect to the Generation Assets and the consummation of the transactions contemplated by the Put Option, including the sale of the Generation Assets, will not result in any material breach of, violation of, or constitute a material default (or event which with the giving of notice or

lapse of time, or both, would become a material default) under, or materially impair Seller’s or any of its Subsidiaries’ rights or alter the rights or obligations of any party under, or give rise to any rights of termination, amendment, modification, acceleration or cancellation of or loss of any benefit under, or result in the creation or imposition of any Encumbrance on any of the assets, rights, or properties of Seller or any of its Subsidiaries (including the Generation Assets) pursuant to any Contract or Permit to which Seller or any of its Subsidiaries is a party, or by which any of the assets, rights or properties of Seller or any of its Subsidiaries is bound or affected.

(ii) The items set forth on Section 2.2(c)(ii) of the Seller Disclosure Schedule are referred to herein as “Seller Required Put Regulatory Approvals”. Notwithstanding anything to the contrary in this Agreement, Seller shall deliver Section 2.2(c)(ii) of the Disclosure Schedule in accordance with the terms of Section 2.9(c) of this Agreement. No consent, waiver, approval, authorization, order or permit of, or declaration, filing or registration with, or notification to any Governmental Authority is required to be made or obtained by Seller or any of its Subsidiaries, in connection with the exercise of the Put Option with respect to the Generation Assets and the consummation of the transactions contemplated by the Put Option, including the sale of the Generation Assets, except those that are set forth on Section 2.2(c)(ii) of the Seller Disclosure Schedule.

(d) Purchaser represents and warrants to Seller as follows:

(i) The execution and delivery of this Agreement by Purchaser (to the extent related to the Put Option) and the consummation of the transactions contemplated by the Put Option, including the purchase of the Generation Assets, will not result in any material breach of, violation of, or constitute a material default (or event which with the giving of notice or lapse of time, or both, would become a material default) under, or materially impair Purchaser’s or any of its Subsidiaries’ rights or alter the rights or obligations of any party under, or give rise to any rights of termination, amendment, modification, acceleration or cancellation of or loss of any benefit under, or result in the creation or imposition of any Encumbrance on any of the assets, rights, or properties of Purchaser or any of its Subsidiaries pursuant to any Contract or Permit to which Purchaser or any of its Subsidiaries is a party, or by which any of the assets, rights or properties of Purchaser or any of its Subsidiaries is bound or affected.

(ii) No consent, waiver, approval, authorization, order or permit of, or declaration, filing or registration with, or notification to any Governmental Authority is required to be made or obtained by Purchaser or any of its Subsidiaries, in connection with the execution and delivery of this Agreement by Purchaser (to the extent related to the Put Option) and the consummation of the transactions contemplated by the Put Option, including the purchase of the Generation Assets, except those that are set forth on Section

2.2(d)(ii) of the Purchaser Disclosure Schedule (the “Purchaser Required Put Regulatory Approvals”).

(e) From and after the date hereof, if requested by Seller, the Parties shall (i) as promptly as practicable, but in no event later than thirty (30) days, after receipt by Purchaser of Section 2.2(c)(i) of the Seller Disclosure Schedule, make the filings required in connection with, and obtain, the Seller Required Put Consents, (ii) as promptly as practicable, but in no event later than thirty (30) days, after receipt by Purchaser of Section 2.2(c)(ii) of the Seller Disclosure Schedule, make the filings required in connection with, and obtain, the Seller Required Put Regulatory Approvals, and (iii) as promptly as practicable, but in no event later than thirty (30) days, after the date of this Agreement, make the filings required in connection with, and obtain, the Purchaser Required Put Regulatory Approvals. The Parties shall make such filings in accordance with the procedures outlined in Section 6.6. Each Party will bear its own costs of the preparation and review of any such filings or obtaining any such consents or approvals. Seller and Purchaser shall have the right to review in advance all characterizations of the information relating to the Put Option and the other transactions contemplated hereby which appear in any filing made in connection with the put transactions contemplated hereby, and the filing Party shall consider in good faith any revisions reasonably requested by the non-filing Party.

2.3 Put Closing. The closing of the transactions contemplated by an Exercise Notice (a “Put Closing”) shall take place at the offices of Skadden, Arps, Slate, Xxxxxxx & Xxxx LLP, Xxxx Xxxxx Xxxxxx, Xxx Xxxx, Xxx Xxxx 00000 at 10:00 a.m., local time, as promptly as practicable, but in no event more than five (5) Business Days, immediately following the date on which the last of the conditions set forth in Section 2.5 hereof is fulfilled or waived with respect to an exercise of the Put Option related to a particular Generation Asset, or at such other time, date and place as Seller and Purchaser shall mutually agree (each a “Put Closing Date”).

2.4 Deliveries at Put Closing. At any Put Closing:

(a) The Parties shall execute and deliver an Asset Purchase Agreement transferring the Generation Asset(s) identified in the applicable Exercise Notice from Seller to Purchaser, substantially in the form attached hereto as Exhibit E (the “Asset Purchase Agreement”) with such other modifications and changes as agreed to between the Parties.

(b) Purchaser shall pay the Exercise Price that corresponds to the Generation Asset(s) that were identified in the applicable Exercise Notice to Seller, in immediately available funds, to the account specified in the Asset Purchase Agreement.

(c) Purchaser shall have received a certificate from an authorized officer of Seller, dated the Put Closing Date, to the effect that, to such officer’s knowledge, the conditions to exercise of the Put Option set forth in Section 2.5 have been satisfied by Seller.

(d) The Parties shall make all deliveries required under the Asset Purchase Agreement.

2.5 Conditions Precedent to Put Exercise. Seller shall be entitled to exercise the Put Option to the extent and only to the extent that each of the following conditions shall have been satisfied, or waived by Purchaser, prior to the delivery of the Exercise Notice:

(a) Since the date of this Agreement, no Generation Asset Material Adverse Effect shall have occurred that is continuing with respect to a Generation Asset for which Seller wishes to exercise the Put Option;

(b) Each of the Seller Required Put Consents, the Seller Required Put Regulatory Approvals and the Purchaser Required Put Regulatory Approvals shall have been obtained;

(c) Purchaser shall have received evidence satisfactory to Purchaser of the release of any and all Encumbrances on each of the Generation Assets (the “Generation Assets Encumbrances”), other than Permitted Encumbrances, with respect to a Generation Asset for which Seller wishes to exercise the Put Option or that such Generation Assets Encumbrances will be released upon closing of the Asset Purchase Agreement related to such Generation Asset;

(d) (i) Each of the representations and warranties of Seller contained in the Asset Purchase Agreement that are qualified as to materiality shall be true and correct in all respects as of the date of the Exercise Notice, (ii) each of the representations and warranties of Seller contained in the Asset Purchase Agreement that are not so qualified shall be true and correct in all material respects as of the date of the Exercise Notice, and (iii) Seller shall be capable of performing in all material respects all of the covenants of Seller (or of the Subsidiaries of Seller who will be party to the Asset Purchase Agreement) set forth in the Asset Purchase Agreement; and

(e) Seller shall have performed and complied in all material respects with the covenants and agreements contained in Section 2.9.

2.6 Alternative Transaction Structure. Notwithstanding any other provision of this Agreement, to the extent that the Parties mutually agree (with respect to any Generation Assets that are the subject of a valid exercise of the Put Option pursuant to Section 2.2) that an alternative structure is preferable to a sale of the Generation Assets pursuant to the Asset Purchase Agreement (such as the sale of an equity interest in or held by a Subsidiary of Seller that owns the applicable Generation Assets), then the Parties shall negotiate in good faith a definitive transaction agreement that reflects such mutually agreed alternative structure; provided that the foregoing shall not affect the applicability of Section 2.2, Section 2.3, Section 2.5, Section 2.7 or Section 2.8 to such alternatively structured transaction.

(i) make any material change in the levels of Inventories (as defined in the Asset Purchase Agreement) customarily maintained with respect to the Generation Assets, except for such changes as are consistent with Good Utility Practices;

(iv) (A) make, revoke or change any material Tax election, (B) except as required by GAAP or FERC, adopt or change any accounting policies or procedures, or any of its methods of reporting income, deductions, or other material items for Income Tax purposes, (C) file any material amendment to a Tax Return, (D) enter into any closing agreement, settle or compromise any material Tax liability, claim or assessment, (E) agree to any extension or waiver of the limitation period to any material Tax claim or assessment, or (F) surrender any right to claim a material tax refund, in each case to the extent that any such actions would be binding on Purchaser;

(v) knowingly engage in any practice, take any action, fail to take any action, or enter into any transaction that would result in any material breach of any representation or warranty of Seller in Section 2.2(c) of this Agreement or in the Asset Purchase Agreement as of the Put Closing Date;

(vi) fail to make commercially reasonable efforts to pursue currently pending regulatory approvals and Permit or Environmental Permit (each as defined in the Asset Purchase Agreement) applications, approvals and renewals relating to the Generation Assets that are reasonably necessary to operate the Generation Assets;

(vii) waive, release, cancel, assign, settle or compromise any action, litigation, claim, arbitration or right relating to the Generation Assets, other than waivers, releases, cancellations, assignments, settlements or compromises that involve only the payment of monetary damages or that would not be binding on Purchaser; and

(viii) agree to enter into any of the transactions set forth in the foregoing paragraphs (i) through (vii).

(b) Subject to all applicable Laws, during the Put Period, Seller will, during ordinary business hours, upon reasonable notice, (i) give Purchaser and its employees, counsel, accountants and other representatives reasonable access to all management personnel engaged in the operation of the Generation Assets and all books, documents and records relating to, and all plants, offices and other facilities and properties constituting, the Generation Assets to the extent in the control of Seller or its Subsidiaries; (ii) permit Purchaser to make such reasonable inspections of the Generation Assets thereof as Purchaser may reasonably request; (iii)

furnish Purchaser with such financial and operating data and other information with respect to the Generation Assets as Purchaser may from time to time reasonably request; (iv) furnish Purchaser a copy of each material report, schedule or other document filed or received by it since the date hereof with respect to the Generation Assets with the SEC, FCC, FERC or any other Governmental Authority having jurisdiction over the Generation Assets; provided, however, that (A) any such inspection shall be conducted in such a manner as not to interfere unreasonably with the operation of the Generation Assets, (B) Seller shall not be required to take any action which would constitute a waiver of the attorney-client privilege, and (C) Seller need not supply Purchaser with any information that Seller is legally prohibited from supplying.

(c) Not later than twenty (20) Business Days after the commencement of the Put Period, Seller shall prepare and deliver, or cause to be prepared and delivered, a draft of each of the schedules, exhibits and annexes contemplated by this Article 2 and the Asset Purchase Agreement for each of the Generation Assets. Seller shall provide prompt updates and revisions to such schedules, exhibits and annexes during the remainder of the Put Period for each of the Generation Assets.

(a) In addition to the rights granted pursuant to Section 6.1, between the date of this Agreement and the earlier of the Designated Interest Closing Date and the Termination Date, Seller will, and will use commercially reasonable efforts to cause the

Each of Seller and Purchaser agrees that, from time to time before and after the Designated Interest Closing Date, they will execute and deliver, and Seller shall, to the extent reasonably possible and subject to any contractual, fiduciary or similar obligation of Seller or any employee, agent, director or officer of the Company appointed by or at the request of Seller, exercise the voting, governance and contractual powers available to any of them to cause the Company and its Subsidiaries to execute and deliver such further instruments, and take, or cause their respective Affiliates to take, such other action, as may be reasonably necessary to carry out the purposes and intents of this Agreement. Each of Seller and Purchaser agrees to use reasonable efforts to refrain from, and to use reasonable efforts to cause the Company and its Subsidiaries to refrain from, taking any action which could reasonably be expected to materially delay the consummation of the transactions contemplated hereby.

6.5 Public Statements. Except as may be required by Law or by obligations pursuant to any listing agreement with or rules of any national securities exchange, Seller and Purchaser’s Parent shall consult with each other prior to issuing any press releases or otherwise making public announcements with respect to the transactions contemplated by this Agreement.

6.6 Consents and Approvals.

(a) Seller and Purchaser shall each file or cause to be filed with the Federal Trade Commission and the Department of Justice (together or individually, the “Antitrust Agency”) any notifications required to be filed under the HSR Act and the rules and regulations promulgated thereunder with respect to the purchase and sale of the Designated Interest. The Parties shall consult with each other as to the appropriate time of filing such notifications and shall agree upon the timing of such filings. All filing fees under the HSR Act shall be borne 50% by Purchaser and 50% by Seller, and each Party will bear its own costs for the preparation of any such filing. Each Party shall (i) respond promptly to any request for additional information made the Antitrust Agency; (ii) promptly notify the other Party of, and, if in writing, furnish the other Party with copies of (or, in the case of material oral communications, advise the other Party orally of), any communications from or with the Antitrust Agency in connection with any of the transactions contemplated by this Agreement; (iii) not participate in any meeting with the Antitrust Agency unless it consults with the other Party in advance and to the extent permitted by the agency gives the other Party the opportunity to attend and participate thereat; (iv) furnish the other Party with copies of all correspondence, filings and communications (and memoranda setting forth the substance thereof) between it and the Antitrust Agency with respect to any of the transactions contemplated by this Agreement; (v) furnish the other Party with such necessary information and reasonable assistance as may be reasonably necessary in connection with the preparation of necessary filings or submission of information to the Antitrust Agency and consistent with appropriate confidentiality safeguards. The Parties shall make, as promptly as practicable (and in any event within thirty (30) days of the date hereof), an appropriate filing of a Notification Report Form pursuant to the HSR Act with respect to the transactions contemplated hereby and use their reasonable best efforts to cause the waiting periods under the HSR Act to terminate or expire at the earliest possible date after the date of filing, and to resist any action, including any legislative, administrative or judicial action, and to have vacated, lifted, reversed or overturned any Governmental Order (whether temporary, preliminary or permanent) that restricts, prevents or prohibits the consummation of any of the transactions contemplated by this Agreement under any applicable Law. Nothing in this Section

6.6(a) shall be construed to require either Party to disclose to the other documents it provides to the Antitrust Agency in response to Item 4(c) of the Notification Report Form.

Seller and Purchaser shall respond promptly to all requests from FERC or its staff for additional information regarding such application and use their respective reasonable best efforts to participate in any hearings, settlement proceedings or other proceedings ordered by FERC with respect to the application. Each Party will bear its own costs of preparation and review of such filings.

(c) As promptly as practicable after the date of this Agreement (and in any event within thirty (30) days of the date hereof), Purchaser and Seller shall file with the NRC an application requesting consent under Section 184 of the Atomic Energy Act and 10 C.F.R. §50.80 for the indirect transfer of the NRC licenses, and approval of any conforming license amendments or other related approvals. In fulfilling their respective obligations set forth in this Section 6.6(c), Seller and Purchaser shall use their reasonable best efforts. Each Party will bear its own costs of the preparation of any such filing and NRC fees shall be borne 50% by Purchaser and 50% by Seller. Thereafter, Purchaser and Seller shall cooperate with one another to facilitate NRC review of the application by providing the NRC staff with such documents or information that the NRC staff may reasonably request or require any of the Parties to provide or generate. For purposes of this Section 6.6(c), such reasonable best efforts shall include providing in accordance with relevant regulatory timeframes any information reasonably requested by the NRC in connection with its review of the license transfer application. Furthermore, such reasonable best efforts with respect to Purchaser shall include agreeing to implement a negation action plan required by the NRC containing customary measures to mitigate foreign ownership, control, and influence.

(d) As promptly as practicable after the date of this Agreement (and in any event within thirty (30) days of the date hereof), Purchaser and Seller shall file with the Committee on Foreign Investment in the United States (“CFIUS”) a joint voluntary notice pursuant to the Exon-Xxxxxx Amendment requesting CFIUS Approval (as defined below). Each of Purchaser and Seller shall use reasonable best efforts to obtain a written notification issued by CFIUS that it has concluded a review of the notice voluntarily filed jointly by Purchaser and Seller and determined not to conduct a full investigation or, if a full investigation is deemed to be required, notification that the United States Government will not take action to prevent the consummation of the transactions contemplated by this Agreement (such determination or notification, the “CFIUS Approval”). Such reasonable best efforts shall include providing in accordance with relevant regulatory timeframes any information requested by CFIUS or any other agency or branch of the United States Government in connection with their review of the transactions contemplated hereby. Furthermore, such reasonable best efforts with respect to Purchaser shall include agreeing to a mitigation agreement with the United States Government

containing customary terms and conditions for transactions in the energy sector in order to secure CFIUS Approval.

(e) Seller, the Company and Purchaser shall cooperate with each other, as promptly as practicable after the date of this Agreement, to take, or cause to be taken, all actions and to do, or cause to be done, all things necessary, proper or advisable to ensure that the conditions set forth in Article 7 are satisfied and to consummate the transactions contemplated by this Agreement as promptly as practicable, including (i) obtaining the Seller Required Regulatory Approvals, the Purchaser Required Regulatory Approvals and the Company Required Regulatory Approvals and (ii) obtaining all authorizations, consents, orders and approvals of, and giving all notices to, third parties that may be or become necessary for the performance of a Party’s obligations under this Agreement and the consummation of the transactions contemplated hereby and by the Ancillary Documents, including those set forth on the Seller Disclosure Schedule and the Purchaser Disclosure Schedule. The Parties shall respond promptly to any requests for additional information made by any Governmental Authorities, use their respective reasonable best efforts to participate in any hearings, settlement proceedings or other proceedings ordered with respect to the applications, and use their respective reasonable best efforts to cause regulatory approval to be obtained at the earliest possible date after the date of filing. Except as otherwise expressly provided in this Section 6.6, each Party will bear its own costs of the preparation and review of any such filing. Seller and Purchaser shall have the right to review in advance all characterizations of the information relating to the transactions contemplated by this Agreement which appear in any filing made in connection with the transactions contemplated hereby and the filing Party shall consider in good faith any revisions reasonably requested by the non-filing Party.

6.7 Tax Matters.

(a) All Transfer Taxes incurred in connection with this Agreement and the transactions contemplated hereby shall be borne equally by Seller and Purchaser. Purchaser will file, to the extent required by applicable Law, all necessary Tax Returns and other documentation with respect to all such Transfer Taxes, and, if required by applicable Law, Seller will join in the execution of any such Tax Returns or other documentation. Prior to the Designated Interest Closing Date, Purchaser will provide to Seller, to the extent possible, an appropriate exemption certificate in connection with this Agreement and the transactions contemplated hereby, due from each applicable Taxing Authority, and the Parties shall comply with all requirements and use commercially reasonable efforts to secure applicable sales tax exemptions for the transactions contemplated by this Agreement.

(b) Except as otherwise provided in Section 6.7(a) above, Seller shall prepare and file or cause to be prepared and filed when due all Tax Returns that are required to be filed by or with respect to the Company or any of its Subsidiaries for taxable years or periods ending on or before the Designated Interest Closing Date, and Seller shall remit or cause to be remitted any Taxes due in respect of such Tax Returns. To the extent permitted or required by applicable Law or administrative practice, the taxable year of each of the Company and any of its Subsidiaries which includes the Designated Interest Closing Date shall be treated as closing on (and including) the Designated Interest Closing Date. For purposes of apportioning between Seller and Purchaser the Taxes of the Company or any of its Subsidiaries or with respect to the

assets of the Company or any of its Subsidiaries for a Straddle Period (which is not treated under the immediately preceding sentence as closing on the Designated Interest Closing Date), such liability shall be apportioned between the period deemed to end at the close of the Designated Interest Closing Date, and the period deemed to begin at the beginning of the day following the Designated Interest Closing Date on the basis of an interim closing of the books, except that Taxes (such as real or personal property Taxes) imposed on a periodic basis shall be allocated on a daily basis.

(c) Any Tax refunds, credits or offsets (“Tax Refunds”) of Taxes of the Company or its Subsidiaries for any Tax period ending on or before the Designated Interest Closing Date shall be for the account of Seller. Any Tax Refunds of Taxes for any Straddle Period shall be allocated between the portion of the taxable period ending on or before the Designated Interest Closing Date and the portion of the taxable period beginning after the Designated Interest Closing Date in a manner consistent with Section 6.7(b).

(d) Notwithstanding any other provision of this Agreement, Seller shall indemnify Purchaser from and against and in respect of (i) Taxes of the Company and its Subsidiaries for any Tax period ending on or before the Designated Interest Closing Date, (ii) with respect to any Straddle Period, Taxes relating to the portion of such Straddle Period ending on and including the Designated Interest Closing Date, (iii) any Taxes (including as a result of Treasury Regulation Section 1.1502-6 or any comparable Law) of any Person that at any time prior to the Designated Interest Closing is or has ever been affiliated with the Company or any of its Subsidiaries or has been a transferee or successor under any Tax allocation, sharing or assumption agreement with respect to such period, (iv) any Taxes resulting from any deferred intercompany item or excess loss account that is triggered on or before the Designated Interest Closing Date, and (v) any Transfer Taxes allocated to Seller pursuant to Section 6.7(a).

(e) The Parties hereby agree that any and all indemnity payments pursuant to this Agreement shall, to the maximum extent permitted by Law, be treated for all U.S. federal, state and local Tax purposes as an adjustment to the Purchase Price.

(f) Notwithstanding any other provision of this Agreement, the obligations of the Parties set forth in this Section 6.7 shall not be subject to any restrictions or limitation other than those expressly set forth in this Section 6.7 and shall survive the Designated Interest Closing.

(g) Purchaser and Seller shall, and shall cause their respective Subsidiaries to, cooperate fully, as and to the extent reasonably requested by the other, in connection with the filing of Tax Returns and any matters with respect to Taxes.

(h) In the event that a dispute arises between Seller and Purchaser relating to Taxes, the Parties shall attempt in good faith to resolve such dispute, and any agreed amount shall be paid to the appropriate Party within ten (10) Business Days of the date on which the Parties reach agreement. If a dispute is not resolved within thirty (30) days of a Party having provided the other Party written notice of a dispute, the Parties shall submit the dispute for determination and resolution to the Independent Accounting Firm, which shall be instructed to determine and report to the Parties in writing, within thirty (30) days after such submission, upon

such disputed amount, and such written report shall be final, conclusive and binding on the Parties. The Independent Accounting Firm shall act as an expert and not as an arbitrator and shall make findings only with respect to the remaining disputes so submitted to it (and not by independent review). Notwithstanding anything in this Agreement to the contrary, the fees and expenses of the Independent Accounting Firm in resolving the dispute shall be borne by Purchaser. Any payment required to be made as a result of the resolution of the dispute by the Independent Accounting Firm shall be made within ten (10) days after such resolution, together with any interest determined by the Independent Accounting Firm to be appropriate. Submission of a dispute to the Independent Accounting Firm shall not relieve any Party from any obligation under this Agreement to timely file a Tax Return or pay a Tax.

(i) At Purchaser’s request, Seller shall make a protective election pursuant to Treasury Regulation Section 1.1502-36(d) to reduce the basis of shares of the Company or its Subsidiaries in order to preclude the reduction of any attributes of the Company or its Subsidiaries pursuant to Treasury Regulation Section 1.1502-36.

(j) To the extent there is a consolidated Section 382 limitation (as determined under Treasury Regulation Section 1.1502-93) attributable to the Company and its Subsidiaries, Seller shall make a timely election (or cause to be made a timely election) under Treasury Regulation Section 1.1502-95 to apportion such Section 382 limitation to the Company and its Subsidiaries.

(k) All Tax allocation agreements between Seller and the Company and its Subsidiaries shall be terminated with respect to the Company and its Subsidiaries on or prior to the Designated Interest Closing Date, and, after the Designated Interest Closing Date, neither the Company nor its Subsidiaries shall be bound thereby or have any further liability or obligation thereunder.

6.8 Advice of Changes. Prior to the Designated Interest Closing Date, each Party will promptly advise the other in writing of any change or discovery occurring after the date hereof that would constitute a material breach of any representation, warranty or covenant of the advising or other Party under this Agreement.

6.9 Spent Nuclear Fuel Fees.

(a) Seller will remain liable for all Spent Nuclear Fuel Fees and any other fees associated with electricity generated at the Facilities and sold prior to the Designated Interest Closing Date, and Purchaser shall have no liability or responsibility therefor. Seller shall be entitled to any funds received from the Department of Energy that reimburse Seller for any costs expended by Seller, the Company and their Subsidiaries prior to the Designated Interest Closing Date for the storage of Spent Nuclear Fuel at the Facilities. Any other funds received by Seller from the Department of Energy representing the default by the Department of Energy on contracts with the Company or any of the Subsidiaries of the Company shall belong to the Company and the Subsidiaries of the Company.

(b) Notwithstanding anything to the contrary in this Agreement, prior to and after the Designated Interest Closing, Seller will retain and prosecute the Department of

Energy Claim and the Company will retain the right to commence and prosecute the Department of Energy Potential Claim, in each case in a manner consistent with its best judgment. The Company shall be entitled to any funds received from the Department of Energy that reimburse the Company for any costs expended by the Company and its Subsidiaries in relation to the resolution of the Department of Energy Potential Claim.

6.10 Insurance. Until the Designated Interest Closing, Seller will maintain, or cause to be maintained, in effect (a) insurance in amounts and against such risks and losses as is customary in the commercial nuclear power industry and (b) not less than the level of property damage and liability insurance for the Facilities as in effect on the date hereof.

6.11 Termination of Certain Arrangements. On or prior to the Designated Interest Closing Date, Seller shall cause the Company and its Subsidiaries to cease participation in the “cash pool” of Seller and its Subsidiaries and any and all intercompany creditor agreements to provide cash to Subsidiaries of Seller that is not available from the cash pool.

6.12 Affiliate Transactions. On or prior to the Designated Interest Closing Date, Seller shall cause the Company and its Subsidiaries to terminate all Affiliate Agreements, except those (a) set forth on Section 6.12 of the Seller Disclosure Schedule, (b) identified in the Transition Services Agreement as continuing, (c) contemplated by the power marketing arrangement specified in the Operating Agreement, or (d) that are not material and are reasonably necessary for the ongoing operations of the Company and its Subsidiaries after the Designated Interest Closing Date, provided that in the case of this clause (d) such Affiliate Agreements do not include or involve any costs, fees or expenses to the Company and its Subsidiaries which are not contemplated by the Transition Services Agreement.

6.13 Transfer of UniStar Interest. On or prior to the Designated Interest Closing Date, the Parties shall restructure, recapitalize, or otherwise rearrange the Company’s ownership (directly or indirectly) of UniStar such that, immediately after the Designated Interest Closing Date, the beneficial interest in UniStar owned, directly or indirectly, by Purchaser and its Affiliates shall not exceed 50 percent. The Parties agree that such restructuring, recapitalization, or rearrangement contemplated in this Section 6.13 shall be done in such a manner as to not cause the Parties to recognize significant amounts of taxable gain, for federal income tax purposes, with respect to their ownership of UniStar and in such a manner so as to preserve the current governance and other rights of each of the Parties with respect to UniStar as of the date hereof.

6.14 Purchaser’s Parent Guarantee.

(a) Purchaser’s Parent unconditionally, absolutely and irrevocably guarantees to Seller the full and prompt payment, as and when due and payable, of the Purchase Price on the Designated Interest Closing Date and the respective Exercise Prices on each Put Option Closing Date, if any, by Purchaser in accordance with Section 1.1 and any adjustments in accordance with Section 1.4 (in the case of the Purchase Price) and in accordance with Section 2.4(b) and the terms of the applicable Asset Purchase Agreement (in the case of an Exercise Price) (the “Purchaser’s Parent Guarantee”); provided that Purchaser’s Parent’s aggregate liability pursuant to this Agreement (including, without limitation, this Section 6.14) shall not, in any

event and under any circumstance and notwithstanding anything to the contrary contained in this Agreement or any agreement or document related hereto, exceed the amount of:

(i) during the period from the date hereof until (A) any Cash Redemption (as defined in the Articles Supplementary) of the Series B Preferred and surrender of such Series B Preferred in accordance with Section 1.3(a), or (B) if there has occurred a Note Redemption (as defined in the Articles Supplementary), such time as the notes issued to Purchaser in connection therewith have been repaid or otherwise retired, $500,000,000 (including any and all liabilities related to the Put Option), or
