In the event that a dispute arises between ZionSolutions and Exelon as to the preparation or the reporting of any material item on a Tax Return to be filed by Exelon or the allocation of such Taxes between ZionSolutions and Exelon, 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 after the date on which the Parties reach agreement. If a dispute is not resolved within thirty (30) days after a Party having provided the other Party written notice of a dispute, the Parties shall submit the dispute for determination and resolution to Deloitte & Touche LLP or such other mutually agreeable firm of CPAs (which is not Exelon’s, ZionSolutions’ or ZionSolutions’ Parent’s independent accountants) of recognized national standing (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 equally by Exelon and ZionSolutions. 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.

5.7 Decommissioning Funds.

5.7.1 For all periods prior to the Put Option Closing Date, ZionSolutions will maintain the Buyer QDF in accordance with NRC requirements and in compliance with the requirements of Section 468A of the Code and the Treasury Regulations. On the Put Option Closing Date or as promptly as reasonably possible thereafter, ZionSolutions shall cause to be transferred to either a QDF or NDF established by Exelon, as directed by Exelon, all of the assets of the Buyer QDF. In the event that any funds remain in the Buyer NDF, such funds shall be transferred to an NDF established by Exelon.

5.7.2 Exelon shall take all steps necessary to satisfy any requirements imposed by the NRC regarding the Decommissioning funds, in a manner sufficient to obtain NRC approval of the transfer of the Amended NRC Licenses from ZionSolutions to Exelon.

5.7.3 The Parties shall not take any actions that would cause the actual Tax consequences of the transactions contemplated by this Agreement to differ from

or be inconsistent with the private letter rulings set forth in the Required Regulatory Approvals.

5.7.4 ZionSolutions shall cause the Trustee of the Buyer QDF to file the Tax Returns for the Buyer QDF for any periods ending on or before the Put Option Closing Date. Prior to the Put Option Closing Date, ZionSolutions shall cause the Trustee of the Buyer QDF to pay estimated Income Taxes for the taxable period that end on the Put Option Closing Date in an amount equal to the estimated Income Tax Liability of the Buyer QDF for the taxable period that ends on the Put Option Closing Date. To the extent the amount of estimated Income Taxes paid pursuant to this Section 5.7.4 is less than the Income Tax Liability of the Buyer QDF for the taxable period that ends on the Put Option Closing Date, any such deficiency will be paid by the Buyer QDF to the extent the Buyer QDF holds sufficient assets or by ZionSolutions if the Buyer QDF holds insufficient assets. To the extent the amount of estimated Income Taxes is greater than the Income Tax Liability of the Buyer QDF for the taxable period that ends on the Put Option Closing Date, any refund of such overpayment will be transferred by ZionSolutions or the Buyer QDF to a QDF established by Exelon and treated as additional Buyer QDF decommissioning funds transferred to Exelon or treated as additional Buyer NDF decommissioning funds transferred to Exelon, as the facts may support, on the Put Option Closing Date.

5.7.5 ZionSolutions shall cause the Trustee of the Buyer QDF and the Buyer NDF to pay final expenses for trustee and investment management fees and other administrative expenses of the Buyer QDF and Buyer NDF relating to transactions on or prior to the Put Option Closing Date to the extent practicable before the Put Option Closing Date. ZionSolutions shall cause the Trustee of the Buyer QDF and the Buyer NDF to notify Exelon in writing of any such Buyer QDF and Buyer NDF expenses due on or after the Put Option Closing Date. Exelon shall direct the trustee of a QDF or NDF established by Exelon to pay the Taxes and expenses identified in the preceding sentence to the extent not paid before the Put Option Closing Date. Exelon shall ensure that the Exelon Decommissioning Trust Agreement allows for the payment of such expenses.

7.1. Indemnification.

7.1.1. Following the Put Option Closing, Exelon shall indemnify, defend and hold harmless ZionSolutions, its officers, directors, employees, Affiliates, shareholders and agents (each, a “ZionSolutions Indemnitee”) from and against any and all claims, demands, suits, losses, liabilities, damages, obligations, payments, costs and expenses (including, without limitation, the costs and expenses of any and all actions, suits, proceedings, assessments, judgments, settlements and compromises relating thereto and reasonable attorneys’ fees and reasonable disbursements in connection therewith) (each, an “Indemnifiable Loss”), asserted against or suffered by any ZionSolutions Indemnitee relating to, resulting from or arising out of: (i) any breach by Exelon of the covenants contained in this Agreement; (ii) the Put Option Liabilities; or (iii) any Third Party Claims against a ZionSolutions Indemnitee arising out of or in connection with Exelon’s ownership of the Put Option Assets or the Facilities following the Put Option Closing Date including contractors’ mechanics’, materialmen’s and similar liens and claims arising after the Put Option Closing Date out of the performance of services or the furnishing of materials relating to the Zion Station Site.

7.1.2. In the event the End State Conditions cannot be satisfied or the Put Option Closing cannot occur because either: (i) there is an injunction, order or decree against Exelon restraining consummation of the transactions contemplated by this Agreement; or (ii) the NRC has not approved the Amended NRC License and transfer to Exelon because of an issue related solely to Exelon’s ability to qualify for the Amended NRC License, then Exelon shall indemnify and hold harmless the ZionSolutions Indemnitees for any costs or liabilities incurred by the ZionSolutions Indemnitees, to the extent not reimbursed by the Buyer QDF, the Buyer NDF or the Buyer Backup NDT, relating directly or indirectly to the

possession and maintenance of the Zion Station Site, including the ISFSI Island, the Spent Nuclear Fuel and the Greater Than Class C Waste, excluding punitive, consequential or special damages (also, an “Indemnifiable Loss”).

7.1.3. Following the Put Option Closing, ZionSolutions shall indemnify, defend and hold harmless Exelon, its officers, directors, members, employees, shareholders, Affiliates and agents (each, an “Exelon Indemnitee”) from and against any and all Indemnifiable Losses asserted against or suffered by any Exelon Indemnitee relating to, resulting from or arising out of: (i) any breach by ZionSolutions of any of the representations and warranties of ZionSolutions contained in this Agreement, but only to the extent that such Indemnifiable Losses exceed One Million Dollars ($1,000,000) individually or Ten Million Dollars ($10,000,000) in the aggregate; (ii) any breach by ZionSolutions of any of the covenants of ZionSolutions contained in this Agreement; and (iii) any Third Party Claims against an Exelon Indemnitee arising out of or in connection with ZionSolutions’ ownership or operation of the Put Option Assets on or prior to the Put Option Closing Date (other than any Third Party Claims that are Put Option Liabilities) including contractors’ mechanics’, materialmen’s and similar liens and claims arising before the Put Option Closing Date out of the performance of services or the furnishing of materials relating to the Zion Station Site.

7.1.4. Except to the extent otherwise provided in Section 5.6.4, the rights and remedies of Exelon and ZionSolutions under this Article 7 are exclusive and in lieu of any and all other rights and remedies which Exelon and ZionSolutions may have under this Agreement or otherwise for monetary relief, with respect to: (i) any breach of or failure to perform any covenant, or agreement set forth in this Agreement after the occurrence of the Put Option Closing; or (ii) the Put Option Liabilities or the Excluded Liabilities, as the case may be. The indemnification obligations of the Parties set forth in this Article 7 apply only to matters arising out of this Agreement. The maximum aggregate exposure for Indemnifiable Losses by ZionSolutions under clause (i) of Section 7.1.3 shall be Twenty-five Million Dollars ($25,000,000); provided, however, that any intentional misrepresentation or fraudulent breach of any representation or warranty of ZionSolutions contained in this Agreement shall not be subject to the foregoing cap on indemnity (it being understood that the Party seeking indemnity in excess of such cap shall bear the burden of proof of establishing the existence of the intentional misrepresentation or fraudulent breach).

7.1.5. Notwithstanding anything to the contrary herein, no Party (including an Indemnitee) shall be entitled to recover from any other Party (including an Indemnifying Party) for any liabilities, damages, obligations, payments, losses, costs or expenses under this Agreement any amount in excess of the actual compensatory damages, court costs and reasonable attorney’s and other advisor fees suffered by such Party. ZionSolutions and Exelon waive any right to recover punitive, incidental, special, exemplary and consequential damages arising in connection with or with respect to this Agreement including, but not limited to, losses or damages caused by reason of plant shutdowns or service interruptions,

loss of use, profits or revenue, inventory or use charges, cost of purchased or replacement power, interest charges or cost of capital, except to the extent any such punitive, incidental, special, exemplary or consequential damages are paid or payable to a Person not a Party or any Affiliate of a Party by reason of a Third Party Claim.

7.2. Defense of Claims.

7.2.1. If any Indemnitee receives notice of the assertion of any claim or of the commencement of any claim, action, or proceeding made or brought by any Person who is not a Party or any Affiliate of a Party (a “Third Party Claim”), with respect to which indemnification is to be sought from an Indemnifying Party, the Indemnitee shall give such Indemnifying Party reasonably prompt written notice thereof, but in any event such notice shall not be given later than twenty (20) calendar days after the Indemnitee’s receipt of notice of such Third Party Claim except at otherwise provided by Section 7.2.6. Such notice shall describe the nature of the Third Party Claim in reasonable detail and shall indicate the estimated amount, if practicable, of the Indemnifiable Loss that has been or may be sustained by the Indemnitee. The Indemnifying Party will have the right to participate in or, by giving written notice to the Indemnitee, to elect to assume the defense of any Third Party Claim at such Indemnifying Party’s expense and by such Indemnifying Party’s own counsel; provided, however, that the counsel for the Indemnifying Party who shall conduct the defense of such Third Party Claim shall be reasonably satisfactory to the Indemnitee. The Indemnitee shall cooperate in good faith in such defense at such Indemnitee’s own expense. If an Indemnifying Party elects not to assume the defense of any Third Party Claim, the Indemnitee may compromise or settle such Third Party Claim over the objection of the Indemnifying Party, which settlement or compromise shall conclusively establish the Indemnifying Party’s Liability pursuant to this Agreement; provided, however, that the Indemnitee provides written notice to the Indemnifying Party of its intent to settle and such notice reasonably describes the terms of such settlement at least ten (10) Business Days prior to entering into any settlement.

7.2.2. If, within twenty (20) days after an Indemnitee provides written notice to the Indemnifying Party of any Third Party Claim, the Indemnitee receives written notice from the Indemnifying Party that such Indemnifying Party has elected to assume the defense of such Third Party Claim as provided in Section 7.2.1, the Indemnifying Party will not be liable for any legal expenses subsequently incurred by the Indemnitee in connection with the defense thereof; provided, however, that if the Indemnifying Party shall fail to take reasonable steps necessary to defend diligently such Third Party Claim within twenty (20) days after receiving notice from the Indemnitee that the Indemnitee believes the Indemnifying Party has failed to take such steps, the Indemnitee may assume its own defense and the Indemnifying Party shall be liable for all reasonable expenses thereof.

7.2.3. Without the prior written consent of the Indemnitee, which consent shall not be unreasonably withheld or delayed, the Indemnifying Party shall not enter into any settlement of any Third Party Claim which would lead to Liability or create any financial or other obligation on the part of the Indemnitee for which the Indemnitee is not entitled to indemnification hereunder. If a firm offer is made to settle a Third Party Claim without leading to Liability or the creation of a financial or other obligation on the part of the Indemnitee for which the Indemnitee is not entitled to indemnification hereunder and the Indemnifying Party desires to accept and agree to such offer, the Indemnifying Party shall give written notice to the Indemnitee to that effect. If the Indemnitee fails to consent to such firm offer within twenty (20) days after its receipt of such notice, the Indemnifying Party shall be relieved of its obligations to defend such Third Party Claim and the Indemnitee may contest or defend such Third Party Claim. In such event, the maximum Liability of the Indemnifying Party as to such Third Party Claim will be the amount of such settlement offer plus reasonable costs and expenses paid or incurred by Indemnitee up to the date of said notice.

7.2.4. Any claim by an Indemnitee on account of an Indemnifiable Loss which does not result from a Third Party Claim (a “Direct Claim”) shall be asserted by giving the Indemnifying Party reasonably prompt written notice thereof, stating the nature of such claim in reasonable detail and indicating the estimated amount, if practicable, but in any event such notice shall not be given later than twenty (20) days after the Indemnitee becomes aware of such Direct Claim, and the Indemnifying Party shall have a period of twenty (20) days within which to respond to such Direct Claim. If the Indemnifying Party does not respond within such twenty (20) day period, the Indemnifying Party shall be deemed to have accepted such claim. If the Indemnifying Party rejects such claim, the Indemnitee will be free to seek enforcement of its right to indemnification under this Agreement.

7.2.5. The amount of any Indemnifiable Loss shall be reduced to the extent that the Indemnitee receives any insurance proceeds with respect to an Indemnifiable Loss. If the amount of any Indemnifiable Loss, at any time subsequent to the making of an indemnity payment in respect thereof, is reduced by recovery, settlement or otherwise under or pursuant to any insurance coverage, or pursuant to any claim, recovery, settlement or payment by, from or against any other entity, the amount of such reduction, less any costs, expenses or premiums incurred in connection therewith (together with interest thereon from the date of payment thereof to the date or repayment at the “prime rate” as published in The Wall Street Journal) shall promptly be repaid by the Indemnitee to the Indemnifying Party.

7.2.6. A failure to give timely notice as provided in this Section 7.2 shall not affect the rights or obligations of any Party hereunder except if, and only to the extent that, as a result of such failure, the Party which was entitled to receive such notice was actually prejudiced as a result of such failure.

8. MISCELLANEOUS PROVISIONS

8.1. Amendment and Modification.

Subject to applicable law, this Agreement may be amended, modified or supplemented only by written agreement of ZionSolutions and Exelon; provided, however, that if as a result of the exercise of remedies under the Pledge Agreement, Exelon controls ZionSolutions by reason of the appointment of a majority of the members of the board of directors of ZionSolutions (but does not otherwise control ZionSolutions through ownership of limited liability company membership interests in ZionSolutions), any amendment, modification or change in the terms of this Agreement made after the date on which Exelon acquired such control shall not be effective without the written consent of ZionSolutions’ Parent, which consent shall not be unreasonably withheld, delayed or conditioned.

8.2. Waiver of Compliance; Consents.

Except as otherwise provided in this Agreement, any failure of any of the Parties to comply with any obligation, covenant, agreement or condition herein may be waived by the Party entitled to the benefits thereof only by a written instrument signed by the Party granting such waiver, but such waiver of such obligation, covenant, agreement or condition shall not operate as a waiver of, or estoppel with respect to, any subsequent failure to comply therewith.

8.3. Survival of Warranties, Covenants and Obligations.

Except as otherwise expressly provided in this Agreement, the warranties, covenants and obligations of the Parties set forth in this Agreement, including without limitation the indemnification obligations of the Parties under Article 7 hereof, shall survive the Put Option Closing indefinitely, and the Parties shall be entitled to the full performance thereof by the other Party hereto without limitation as to time or amount (except as otherwise specifically set forth herein).

8.4. Notices.

All notices and other communications hereunder shall be in writing and shall be deemed given if delivered personally or by facsimile transmission, or mailed by overnight courier or registered or certified mail (return receipt requested), postage prepaid, to the recipient Party at its address (or at such other address or facsimile number for a Party as shall be specified by like notice; provided, however, that notices of a change of address shall be effective only upon receipt thereof):

8.5. Assignment.

This Agreement and all of the provisions hereof shall be binding upon and inure to the benefit of the Parties and their respective successors and permitted assigns, but neither this Agreement nor any of the rights, interests or obligations hereunder shall be assigned by any Party, including by operation of law, without the prior written consent of each other Party, such consent not to be unreasonably withheld, nor is this Agreement intended (except as specifically provided herein) to confer upon any other Person except the Parties any rights, interests, obligations or remedies hereunder. Any assignment in contravention of the foregoing sentence shall be null and void and without legal effect on the rights and obligations of the Parties hereunder. No provision of this Agreement shall create any third party beneficiary rights in any employee or former employee of ZionSolutions (including any beneficiary or dependent thereof) in respect of continued employment or resumed employment, and no provision of this Agreement shall create any rights in any such Persons in respect of any benefits that may be

provided, directly or indirectly, under any employee benefit plan or arrangement except as expressly provided for thereunder. In the event Exelon assigns this Agreement with the consent of ZionSolutions pursuant to this Section 8.5, such assignee shall be defined as “Exelon” for all purposes hereunder thereafter.

8.6. Governing Law.

This Agreement shall be governed by and construed in accordance with the law of the State of Illinois (without giving effect to conflict of law principles) as to all matters, including but not limited to matters of validity, construction, effect, performance and remedies. THE PARTIES HERETO AGREE THAT VENUE IN ANY AND ALL ACTIONS AND PROCEEDINGS RELATED TO THE SUBJECT MATTER OF THIS AGREEMENT SHALL BE IN THE UNITED STATES DISTRICT COURT FOR THE NORTHERN DISTRICT OF ILLINOIS (EASTERN DIVISION) OR ANY STATE COURT SITUATED THEREIN.

SERVICE OF PROCESS MAY BE MADE IN ANY MANNER RECOGNIZED BY SUCH COURTS. EACH OF THE PARTIES HERETO IRREVOCABLY WAIVES ITS RIGHT TO A JURY TRIAL WITH RESPECT TO ANY ACTION OR CLAIM ARISING OUT OF ANY DISPUTE IN CONNECTION WITH THIS AGREEMENT OR THE TRANSACTIONS CONTEMPLATED HEREBY.

8.7. Counterparts.

This Agreement may be executed in two or more counterparts, each of which shall be deemed an original, but all of which together shall constitute one and the same instrument.

8.8. Attachments and Schedules.

Except as otherwise provided in this Agreement, all Attachments and Schedules referred to herein are intended to be and hereby are specifically made a part of this Agreement. Any fact or item disclosed on any Schedule to this Agreement shall be deemed disclosed on all other Schedules to this Agreement to which such fact or item may reasonably apply so long as such disclosure is in sufficient detail to enable a Party to identify the facts or items to which it applies. Any fact or item disclosed on any Schedule hereto shall not by reason only of such inclusion be deemed to be material and shall not be employed as a point of reference in determining any standard of materiality under this Agreement.

8.9. Entire Agreement.

This Agreement including the Attachments, Schedules, documents, certificates and instruments referred to herein or therein, and any other documents that specifically reference this Section 8.9, embody the entire agreement and understanding of the Parties hereto in respect of the transactions contemplated by this Agreement and shall supersede all previous oral and written and all contemporaneous oral negotiations, commitments and understandings including, without limitation, all letters, memoranda or other documents or communications, whether oral,

written or electronic, submitted or made by: (i) Exelon or its Representatives to ZionSolutions or its Representatives; or (ii) ZionSolutions or its Representatives to Exelon or its Representatives, in connection with the sale process that occurred prior to the execution of this Agreement or otherwise in connection with the negotiation and execution of this Agreement. No communications by or on behalf of ZionSolutions, including responses to any questions or inquiries, whether orally, in writing or electronically, and no information provided in any data room or any copies of any information from any data room provided to Exelon or any other information shall be deemed to: (i) constitute a representation, warranty, covenant, undertaking or agreement of ZionSolutions; or (ii) be part of this Agreement.

8.10. Acknowledgment; Independent Due Diligence.

Exelon acknowledges that ZionSolutions has not made any representation or warranty, express or implied, as to the accuracy or completeness of any information regarding the Put Option Assets or Put Option Liabilities not included in this Agreement and the Schedules hereto. Exelon further acknowledges that: (i) Exelon, either alone or together with any individuals or entities that Exelon has retained to advise it with respect to the transactions contemplated by this Agreement, has knowledge and experience in transactions of this type and in the business to which the Put Option Assets or Put Option Liabilities relate and is therefore capable of evaluating the risks and merits of acquiring the Put Option Assets and the Put Option Liabilities; (ii) Exelon has relied on its own independent investigation, and has not relied on any information or representations furnished by ZionSolutions or any Representative of ZionSolutions (except as specifically set forth in this Agreement), in determining to enter into this Agreement; (iii) neither ZionSolutions nor any Representative of ZionSolutions has given any investment, legal or other advice or rendered any opinion as to whether the purchase of the Put Option Assets or the assumption of the Put Option Liabilities is prudent, and Exelon is not relying on any representation or warranty by ZionSolutions or any representative or agent of ZionSolutions except as set forth in this Agreement; (iv) Exelon has made independently and without reliance on ZionSolutions (except to the extent that Exelon has relied on the representations and warranties of ZionSolutions in this Agreement) its own analysis of the Put Option Assets, the Put Option Liabilities and of ZionSolutions for the purpose of acquiring the Put Option Assets and assuming the Put Option Liabilities as it considered appropriate to make its evaluation.

8.11. Bulk Sales Laws.

Exelon acknowledges that, notwithstanding anything in this Agreement to the contrary, ZionSolutions will not comply with the provision of the bulk sales laws of any jurisdiction in connection with the transactions contemplated by this Agreement. Exelon hereby waives compliance by ZionSolutions with the provisions of the bulk sales laws of all applicable jurisdictions.

8.12. No Joint Venture.

Nothing in this Agreement creates or is intended to create an association, trust, partnership, joint venture or other entity or similar legal relationship among the Parties, or impose a trust, partnership or fiduciary duty, obligation, or liability on or with respect to the

Parties. Except as expressly provided herein, neither Party is or shall act as or be the agent or representative of the other Party.

8.13. Change in Law.

If and to the extent that any Laws or regulations that govern any aspect of this Agreement shall change, so as to make any aspect of this transaction unlawful, then the Parties agree to make such modifications to this Agreement as may be reasonably necessary for this Agreement to accommodate any such legal or regulatory changes, without materially changing the overall benefits or consideration expected hereunder by any Party.

8.14. Severability.

Any term or provision of this Agreement that is held invalid or unenforceable in any situation shall not affect the validity or enforceability of the remaining terms and provisions hereof or the validity or enforceability of the offending term or provision in any other situation; provided, however, that the remaining terms and provisions of this Agreement may be enforced only to the extent that such enforcement in the absence of any invalid terms and provisions would not result in: (i) deprivation of a Party of a material aspect of its original bargain upon execution of this Agreement; (ii) unjust enrichment of a Party; or (iii) any other manifestly unfair or inequitable result.

8.15. Specific Performance.

Each Party acknowledges and agrees that the other Party would be damaged irreparably in the event any of the provisions of this Agreement are not performed in accordance with their specific terms or otherwise are breached. Accordingly, each Party agrees that the other Party shall be entitled to an injunction or injunctions to prevent breaches of the provisions of this Agreement and to enforce specifically this Agreement and the terms and provisions hereof in addition to any other remedy to which it may be entitled, at law or in equity.
