2. The parties intend that the Insurer conduct its activities so as not to be subject to the insurance regulation of any jurisdiction iPther than Bermuda and Delaware.

Accordingly, the parties expressly recognize and agree that paragraph 1 above does not evidence an intent by the parties to (a) give jurisdiction over the Insurer to the insurance regulatory authority of any jurisdiction other than Bermuda and Delaware; or (b) make applicable to this Policy any of the insurance laws or regulations (including those which specify the terms of the by-laws and contracts of mutual insurance companies) of any jurisdiction, including New York, other than to the extent such laws of Bermuda and Delaware are applicable; or (c) otherwise have the laws of Bermuda or Delaware apply to the construction or enforcement of this Policy.

NEIL Primary Property - October 2006 10

E. Concealment, Fraud The Insurer shall have no obligation to make any payment under this Policy if, whether before or after a Loss, any Insured has willfully concealed or misrepresented in writing any material fact or circumstance concerning this insurance or the subject thereof, or the interest of any Insured therein, or in case of any fraud or false swearing by any Insured relating thereto; but the application of this provision shall not affect the Member Insured's obligation to pay the Retrospective Premium Adjustment callable by the Insurer under this Policy.

F. Deductibles There shall be deducted from the amount of each and every Loss the Deductible stated in Item 8 of the Declarations. In the event that more than one Deductible applies to any one Loss, then only the largest Deductible for that Loss shall be applied.

G. Dispute Resolution

1. The Insurer and the Insured mutually acknowledge that the form, terms and conditions of the Policy have been formulated by representatives of the participating utilities in order to provide insurance coverage which is vital to all participants. It was desired that the Insurer serve as a financially stable and reliable entity, responsive to the coverage needs of its participants, and providing coverage fairly and equitably as to each Insured, but taking equally into account fairness and equity as to all insureds as a group. While every effort has been made to define with clarity and precision the scope of coverage and other policy provisions, the Insurer and the Insured mutually acknowledge that situations may arise where the terms of the Policy are disputed. For the foregoing reasons, the Insurer and the Insured agree that the following principles shall govern the interpretation of the Policy:

(a) Even-handedness and fairness to both the Insurer and the Insured; (b) The intentions of the Insurer and the Insured, including any extrinsic evidence of intent; (c) The practice of the Insurer and the Insured in interpreting and applying the Policy; (d) The cooperative rather than adversarial relationship between the Insurer and the Insured; and (e) The contract construction rule of contra proferentem is not applicable to this insurance policy.

2. The Insurer and Insured agree to endeavor to resolve any dispute between them by means of voluntary proceedings to be agreed upon between them. In the event of a dispute, either the Insurer or the Insured may request the other to participate in an alternative dispute resolution proceeding. The Insurer and the Insured acknowledge, depending upon the circumstances, that an ap'propriate proceeding may include but is not limited to one or more of the following: early neutral evaluation, mediation, mini-trial, neutral fact finding, or senior peer review. In the absence of the parties agreeing to participate in an alternative dispute resolution process, the Insurer will agree, at the request of the Insured, to submit the dispute to senior peer review, unless otherwise determined by the Insurer's Board of Directors. The Insurer agrees to pay the fees and expenses of any neutral party associated with the procedures. The use of any such or other proceeding is voluntary to both the Insurer and Insured, but each acknowledges that it is in the best interests of the mutual enterprise to resolve disputes by such voluntary means where possible, and without the need for final and binding arbitration between them.

3. The Insured and Insurer agree in good faith to consider, in connection with any dispute, the Statement of Dispute Resolution Principles adopted by the Insurer's Board of Directors and Members, as it may be amended from time to time.

4. Any claim or controversy between the Insured and the Insurer as to any matters arising out of or relating to this Policy, which is not settled between themselves, pursuant to paragraph 2 above or otherwise, shall be submitted at the request of either the Insured or the Insurer to arbitration in New York City unless the parties agree as to another location. Arbitration of a dispute is final and binding. The Insured and the Insurer shall try in good faith to agree on the appointment of a sole arbitrator to settle the dispute. In the event the parties cannot agree on the appointment of a sole arbitrator, they can agree to have a sole arbitrator appointed by the then President of the Association of the Bar of the City of New York or in the absence of agreement to do so, a three-person arbitration panel shall be appointed. In the event that either the Insured or the Insurer determines that the dispute is not appropriate for a sole arbitrator, a three-person arbitration panel shall be appointed.

In such instance, the Insured shall appoint one arbitrator and the Insurer another; the two so appointed shall select the third. If the two arbitrators fail to agree on a third arbitrator for a period of sixty calendar days from the date of appointment of the second arbitrator, then on request of the Insured or the Insurer such third arbitrator shall be selected by the then President of the Association of the Bar of the City of New York. The Insured and the Insurer may by express agreement determine the arbitral procedures to be followed; in the event the parties do not agree, New York law, including the statutory rules on arbitration, shall govern all matters of procedure.

The arbitrators shall first determine the liability of the parties as to the dispute, claim or controversy, and then, only if necessary, determine the type and amount of relief to be granted. The arbitrators shall award reasonable attorney's fees and costs to the prevailing party in such amount as they determine appropriate, not to exceed the amount of fees and costs incurred by the non-prevailing party. For this purpose, the NEIL Primary Property - October 2006 12

fees incurred shall be calculated at reasonable prevailing hourly billing rates and include all reasonable out-of-pocket expenses.

5. To the extent that any dispute, claim or controversy between the Insured and the Insurer hereunder is not subject to arbitration for any reason whatever, the United States District Court for the Southern District of New York shall have exclusive jurisdiction thereof. For such purpose, the Insured agree to accept, without objection to form or manner, service of process to the person identified in Item 11 of the Declarations.

For such purpose, the Insurer agrees to accept, without objection to form or manner, service of process by registered mail directed to Nuclear Electric Insurance Limited, 1201 Market Street, Suite 1100, Wilmington, Delaware 19801. The foregoing consents to service of process are not intended nor shall they be construed to extend to any dispute, claim, controversy, cause of action, or other matter other than as stated in this paragraph.

H. Headings The headings in this Policy are inserted for convenience only and shall not be deemed to constitute a part hereof.

1. Inspection and Suspension I1. The Insurer shall be permitted, but not obligated, to perform or to have performed on its behalf, inspections of the Insured Property at any reasonable time. All inspections and inspection reports made by or on behalf of the Insurer are made solely for insurance purposes. Inspection reports are based upon conditions, practices and property observed and information made available at the time of the inspection, and shall not be deemed to identify all hazards or to indicate that other hazards do not exist. The Insurer and those performing inspections on its behalf shall not be responsible for the correction or control of any conditions, practices or property.

Notwithstanding any other agreement, express or implied, to the contrary, neither the right to make an inspection nor the making of an inspection, nor any advice or report resulting therefrom, shall constitute or be construed as an undertaking on behalf of or for the benefit of the Insureds or others to determine or warrant that the facilities, operations or property are safe or healthful, or are in compliance with any law, rule, regulation, procedure or standard.

2. Upon discovery of a dangerous condition with respect to any machine, vessel, or part thereof, a representative of the Insurer may request that such machine, vessel or part thereof be taken out of service without delay so that corrective measures may be instituted.

It shall be the obligation of the Insureds to ensure that the Insurer is accorded the right of inspection under paragraph 1 above and to ensure compliance with any requests by the Insurer pursuant to paragraphs 2 and 3 above. The failure of the Operator to permit the Insurer to inspect or to comply with such a request of the Insurer shall be deemed a breach of this obligation on the part of the Insureds.

5. If a request made under paragraph 2 or 3 above is not complied with, a representative of the Insurer may immediately suspend coverage as to any Property Damage arising out of any Accident which results from such non-compliance, by written notice handed, mailed or delivered to the Member Insured.

6. The Insurer may suspend coverage under this Policy, in whole or in part, with respect to the Insured Property, without prior notice .to the Insureds, if(i) the NRC suspends or revokes for any reason the operating license issued with respect to any Unit on such Insured Property, or (ii) the NRC issues a shutdown order with respect to such Unit, or (iii) the NRC issues a confirmatory order keeping such Unit shut down.

7. The insurance suspended in accordance with paragraphs 5 and 6 above may be reinstated by the Insurer, but only by an endorsement issued to form a part of this Policy. The suspension of the insurance under this Policy shall not affect the obligation of the Member Insured to pay the Retrospective Premium Adjustment callable by the Insurer under this Policy.

J. Insurer's Options It shall be the option of the Insurer to take all, or any part, of the destroyed or damaged Insured Property at the agreed or appraised value, and also to decontaminate or otherwise repair, or to rebuild or replace such Insured Property destroyed or damaged with other of like kind and quality within a reasonable time, on giving notice of its intention to do so within thirty (30) days after the receipt of the Proof of Loss as herein provided.

K. Limits

Notwithstanding anything contained herein to the contrary, the Insurer's liability hereunder shall be the amount payable to the Member Insured but for this provision, less any amount owed to the Insurer by the Insureds, including amounts owed to the Insurer by the Insureds under this Policy or any other agreement or policy.

4. The Member Insured's recovery under Section I.A. 1 and I.A.2 of this Policy shall not be decreased because the replacement cost or Actual Cash Value, whichever is applicable, of the Insured Property is less than the Insurer's limit of liability.

L. Mortgagee Interests and Obligations I1. If a Loss hereunder is assigned or made payable, in whole or in part, to a designated mortgagee not named herein as an Insured, such interest in this Policy may be canceled upon sixty (60) days' written notice of cancellation mailed or delivered to such mortgagee.

2. If the Insureds fail to meet the requirements stated herein in the case of Accidental Property Damage, such mortgagee, upon notice, shall render a written estimate of Loss within sixty (60) days and shall render Proof of Loss in the form approved by the Insurer within twelve (12) months thereafter and shall be subject to the provisions hereof relating to appraisal, arbitration and time of payment and of bringing suit. If the Insurer shall claim that no liability exists as to the mortgagor or owner, it shall, to the extent of payment of loss to the mortgagee, be subrogated to all the mortgagee's rights of recovery, but without impairing mortgagee's right to sue; or it may pay off the mortgage debt and require an assignment thereof and of the mortgage. Other provisions relating to the interests and obligations of such mortgagee may be added hereto by endorsement.

M. Natural Hazards I1. Windstorm Loss Each Loss by windstorm, tornado or hurricane shall constitute a single Accident; provided, if more than one windstorm, tornado or hurricane should occur within any period of seventy-two (72) hours commencing during the term of this Policy, and such windstorms, tornados or hurricanes have a common origin or are caused by a single atmospheric disturbance, then such windstorms, tornados or hurricanes shall be deemed to be a single windstorm, tornado or hurricane.

2. FloodLoss Each Flood shall be deemed a separate Accident; provided that if more than one Flood should occur within any period of ninety-six (96) hours commencing during the term of this Policy and such Floods have a common origin or are caused by a single Accident, then such Floods shall be d&eemed to be a single Flood.

N. Other Insurance The Insurer shall not be liable if at the time of the Accident there is any other insurance which would attach if this insurance had not been qffected, except that this insurance shall apply only as excess and in no event as contributory insurance, and then only after all other insurance has been exhausted.

0. Policy Decisions and Notice Except as provided in paragraph Q of Section V, all decisions or actions made or taken with respect to this Policy may only be taken or made by the first named Member Insured and all such decisions or actions shall be binding on all Insureds. Such decisions or actions shall include, without limitation, decisions to give or not give notices of losses, to file or not file proofs of loss and to bring or not bring an action under the dispute resolution provision. No decision or action with respect to this Policy may be made or taken by anyone other than the Insurer and the first named Member Insured.

NEIL Primary Property - October 2006 19

V. Valuation

1. The value of the Insured Property at the time.of an Accident shall be the replacement cost of such Insured Property, but only if siuch Insured Property as is damaged or destroyed is replaced within a reasonable time with identical or like kind property on the same premises and intended for the same occupancy and use. In all other cases, the value of the Insured Property at the time of loss shall be the Actual Cash Value of such Insured Property, notwithstanding that the Policy may refer to the replacement cost of such Insured Property. The Member Insured may elect first to make claim under this Policy on an Actual Cash Value basis and may make further claim on a replacement cost basis, provided the Insurer is notified in writing within one hundred and eighty (180) days after the Accident of the Member Insured's intent to make such further claim and such claim is filed within three hundred and sixty-five (365) days of such notice.

X. When Loss Payable.

The amount of Loss for which the Insurer may be liable shall be payable as soon as practicable and in any event within sixty (60) days after the Proof of Loss is received by the Insurer and ascertainment of the Loss is made either by agreement between the Member Insured and the Insurer expressed in writing or by the filing with the Insurer of an award as herein provided. Where only a partial Proof of Loss has been provided to the Insurer and the Insurer's liability for the Property Damage is uncontested, the Insurer may, in its sole discretion, make partial payment to the Insured. Nevertheless, the Insurer shall have no obligation to make such partial payment.

VI. RETROSPECTIVE PREMIUM ADJUSTMENT The Member Insured agrees to pay to the Insurer the Retrospective Premium Adjustment under the terms and conditions hereinafter set forth.

1. The Insurer may make demand for the Retrospective Premium Adjustment in whole or in one or more parts from time to time, but only to the extent necessary, in the sole discretion of the Board of Directors of the Insurer, to cover Losses incurred by the Insurer under this Policy and all Other Insurance Policies with coverage effective during the Policy Year (specified in Item 3.B of the Declarations).

2. That portion of the Retrospective Premium Adjustment demanded by the Insurer shall be paid to the Insurer by wire transfer or other method acceptable to the Insurer within twenty (20) business days after demand. The Insurer may, without first pursuing any rights it may have against any Delinquent Member, make such number of further demands upon the Member Insured, including any Delinquent Member, for further portions of the Retrospective Premium Adjustment, to be payable twenty (20) business days after demand, as may be needed to obtain Retrospective Premium

'Adjustment from the Member Insureds of the'Insurer under this Policy and all Other Insurance Policies with coverage effective during the Policy Year sufficient, in the sole discretion of the Board of Directors of the Insurer, to cover Losses under this Policy and all Other Insurance Policies with coverage effective during the Policy Year. The fact that the Insurer has received sufficient Retrospective Premium Adjustment from such Member Insureds shall not bar the Insurer from pursuing the Insurer's rights against any Delinquent Member.

3. When, for any purpose hereunder, it becomes necessary to calculate the obligation of the Member Insured for the Retrospective Premium Adjustment, it will be calculated as follows:

(a) The amount of the Retrospective Premium Adjustment shall be equal to the product of (i) the Multiple selected by the Board of Directors of the Insurer as required to meet Losses under this Policy and all Other Insurance Policies with coverage effective during the Policy Year, times (ii) the Premium, or if such Premium is for a period shorter than a calendar year, such Premium multiplied by a fraction the numerator of which is 365 and the denominator NEIL Primary Property - October 2006 21

of which is the number of days in the policy period specified in Item 3A of the Declarations.

(b) The policy year to which any Retrospective Premium Adjustment relates shall be determined by the Board of Directors of the Insurer at the time it makes the call for such Retrospective Premium Adjustment based on the date of the Accident under this Policy or any Other Insurance Policy giving rise to the obligation which such Retrospective Premium Adjustment is designed to satisfy. The aggregate of all Retrospective Premium Adjustments under this Policy shall not exceed the Retrospective Premium Adjustment set forth in Item 5.B of the Declarations.

(c) Subject to the provisions with respect to calls made in the event of failure to pay by Delinquent Members, the amount of any call for a Retrospective Premium Adjustment hereunder shall bear the same relation to the total Retrospective Premium Adjustment, payable by all Member Insureds of the Insurer under such call as the highest Premium determined under subparagraph (a)(ii) above bears to the aggregate Premiums, used to calculate the total of all such calls, under this Policy and all Other Insurance Policies with coverage effective during the Policy Year.

(d) The obligation of the Member Insured for the Retrospective Premium Adjustment shall be and remain in full force and effect and all the above calculations shall be made without regard to whether or not the Insurer has any obligation to make payments under this Policy or this Policy is canceled or suspended.

4. The Multiple is no higher than the Multiple in any Other Insurance Policy with insurance coverage effective during the Policy Year.

5. The Board of Directors of the Insurer in its sole discretion may adjust downward the Multiple stated in this Policy and any Other Insurance Policy with coverage effective during the Policy Year to a new lower Multiple, and the Retrospective Premium Adjustment callable under this Policy and any such Other Insurance Policy shall be reduced by a like proportionate amount. No downward adjustment in such Multiple and corresponding adjustment in any such Retrospective Premium Adjustment may be made with respect to any Retrospective 'Premium Adjustment which has been assigned by the Insurer, or in any Other Insurance Policy with coverage effective during the Policy Year, if the Multiple in any such Other Insurance Policy, after adjustment, would be less than the Multiple, after adjustment, in this Policy, unless a similar downward adjustment is made in the Multiple in this Policy, together with a corresponding adjustment in the Retrospective Premium Adjustment.

NEIL Primary Property - October 2006 22

6. The liability of the Member Insured shall be limited to the Premium and the Retrospective Premium Adjustment or any unpaid portion thereof due to the Insurer under the terms of this Policy. No Member Irisured shall be subject to any contingent liability or be required to pay any dues or assessments in addition to such Premium and Retrospective Premium Adjustment due under this Policy and those due under any Other Insurance Policies as such Member Insured may have with the Insurer.

The liability of the Member Insured for the Retrospective Premium Adjustment for the Policy Year shall cease six (6) years after the end of the Policy Year, unless prior demand is made therefor.

7. It is agreed that the obligation of the Member Insured to pay any Retrospective Premium Adjustment due under any Other Insurance Policy between the Insurer and the Member Insured which terminated on or before the inception date of this Policy is an obligation of the Member Insured under this Policy. It is also agreed that the terms and the amount of such obligation shall be determined by reference to the Other Insurance Policy under which such obligation arose, notwithstanding that such Other Insurance Policy may no longer be in effect.

8. The liability of each Member Insured, if there be more than one, for the Retrospective Premium Adjustment under this Policy shall be several and not joint and in proportion to their respective interests specified in the Declarations.

9. In the event the Insurer has available credit facilities from lenders, the Board of Directors of the Insurer may, in its sole discretion, utilize such facilities to finance Losses incurred by the Insurer under this Policy and all Other Insurance Policies.

The Insurer may assign to the lenders the Insurer's interest in the Retrospective Premium Adjustment, in whole or in part, including, in the event the Insurer defaults on its obligations to such lenders, the right to call such interest assigned.

Such assignment may be made and shall only be effective with respect to the financing of those Losses for which the Retrospective Premium Adjustment could be called. In the event any assignment is made, the Insurer shall give prompt notice thereof to the Member Insured. Each Member Insured shall, upon the request of the Insurer, give acknowledgment of its liability for the Retrospective Premium Adjustment to each of the lenders involved.

VII. MEMBERSHIP Each Member Insured becomes a member of the Insurer as part of obtaining insurance from the Insurer, and as such, is entitled to the privileges and benefits, and by entering into this Policy agrees to be subject to and bound by the obligations and duties of membership. These are more fully set forth in the Insurer's Memorandum of Association and in the Bye-Laws and any amendments thereto, each of which is hereby incorporated into and made a part of this Policy. In no event shall any amendment to the Memorandum of Association or the Bye-Laws increase the amount of Premium or Retrospective Premium Adjustment payable or callable hereunder.

NEIL Primary Property, October 1, 2006 I

NUCLEAR ELECTRIC INSURANCE LIMITED POLICYHOLDER DISCLOSURE NOTICE OF TERRORISM INSURANCE COVERAGE Coverage for acts of terrorism is already included in your current policy. However, under NEIL's Payment for Acts of Terrorism endorsement, your recovery for losses stemming from an act of terrorism might have been limited. You should know that in accordance with the Terrorism Risk Insurance Act of 2002 (the "Act"), as extended on December 22, 2005, under your existing coverage, NEIL's Payment for Acts of Terrorism endorsement would be inapplicable to any losses caused by certified acts of terrorism under the Act and such losses would be partially reimbursed by the United States under a formula established by federal law. Under this formula, the United States pays 90% (85% for the calendar year 2007) of covered terrorism losses exceeding the statutorily established deductible paid by the insurance company providing the coverage, up to an annual national limit. NEIL is neither increasing, nor attributing any portion of, your annual premium for terrorism coverage.

NUCLEAR ELECTRIC INSURANCE LIMITED WILMINGTON, DE.

(b) If such Property Losses for all Insureds exceed the amount determined under paragraph 1 above, the Insured's maximum recovery shall be the amount determined under paragraph 1 above times a fraction, the numerator of which is the Insured's recovery for the Property Losses resulting from Accidental Property Damage, but for this Section, and the denominator of which is the sum of all Insureds' recovery for Property Losses resulting from Accidental Property Damage under all applicable Nuclear Insurance Policies, including this Policy, but for this Section.

(c) Notwithstanding paragraph I and subparagraph 2(b) above, if the payments made pursuant to subparagraph 2(b) exhaust the amount determined under paragraph 1, without paying for all the Insured's Property Losses, the Insured shall recover such additional amounts that the Insurer recovers from reinsurance, indemnity, or other source, for the Insured's Property Losses.

4. Relevant Period The twelve-month period specified above shall commence on the date of the first Accidental Property Damage caused by an Act of Terrorism.

1. The Insurer agrees to indemnify the Insureds and their legal representatives.

(a) for all expenses necessarily incurrediby the Insureds in discharging their legal obligation or liability to protect the public health and safety following Accidental Property Damage, as required by the Act, provided such expenses would otherwise be covered under paragraphs I. 1(b) or 1.1(c) hereof, but for this paragraph 1.1(a);

(b) for all expenses necessarily incurred by the Insureds to remove debris of and to decontaminate the Insured Property following Accidental Property Damage; and (c) for all other losses covered under the Underlying Insurance Policy; which, except with respect to Functional Total Loss Coverage, and as provided in subsection 1.7 hereof, would be covered by such Underlying Insurance Policy if the limit of the Underlying Insurance Policy thereunder were not exhausted, but only to the extent that the amount of Accidental Property Damage exceeds the Attachment Point.

2. (a) In the event of Accidental Property Damage which (i) exceeds the Attachment Point and includes Nuclear Liability Coverage; (ii) is covered under paragraphs I. 1of the Policy oirwould be covered under that paragraph but for the availability of insurance under the Underlying Insurance Policies; and (iii) results in permanent cessation of nuclear operations at a Unit, the Insurer agrees to indemnify the Insureds and their legal representatives, subject to paragraph (b) hereof for the Functional Value of the undamaged Functional Property following Accidental Property Damage.

(b) In recognition of the difficulty in accurately measuring the Functional Value of the undamaged Functional Property and the desirability of avoiding over-recovery by the Insureds, the parties agree that the Insurer's liability shall be calculated by multiplying the total Functional Value of the undamaged Functional Property by the percentage specified in Item 8 of the Declarations.

(c) In the event that the Unit returns to commercial nuclear operation, the Insureds shall repay to the Insurer the entire amount paid pursuant to paragraph 1.2(a), together with interest thereon, calculated quarterly at the 90-day United States Treasury Bill interest rate in effect on the first business day of each calendar quarter.

3. The Insureds' recovery under the Nuclear Liability Coverage or the Debris Removal and Decontamination Coverage shall not be decreased because the Actual Cash Value (or, if applicable, the Replacement Cost) of the Insured Property is less than the Insurer's limit of liability.

4. (a) Except as provided in paragraph 1.4(b) below, the amount of insurance available for payment to the Insureds with respect to Losses under the Debris Removal and Decontamination Coverage, the Property Damage Coverage, or the Functional Total Loss Coverage prior to the completion of indemnification under the Nuclear Liability Coverage shall be calculated by subtracting the Specified Nuclear Liability Amount from the Amount specified in Item 6 of the Declarations, as such amount may be reduced pursuant to the terms of this Policy.

(b) At the request of the Insureds, the amount calculated in accordance with paragraph 1.4(a) above may be increased to include an amount equal to all or part of the Specified Nuclear Liability Amount, but only to the extent of amounts for which the Member Insured attests that:

(i) the Insureds are entitled.to claim under other valid and collectible insurance covering the same, expenses covered by the Nuclear Liability Coverage; (ii) the Insureds will claim under such other insurance and use such proceeds to discharge the Insureds' legal obligation or liability to protect the public health and safety following Accidental Property Damage, as required by the Act; and (iii) the payment or use of all or part of the Specified Nuclear Liability Amount for Losses under the Debris Removal and Decontamination Coverage, the Property Damage Coverage, and/or the Functional Total Loss Coverage does not violate any regulation or order of the NRC.

In case the Member Insured and the Insurer shall fail to agree as to the amount of Property Damage, then, on the written demand of either, each shall select a competent and disinterested appraiser and notify the other of the appraiser selected within twenty (20) days of such demand.

An award in writing, so itemized, of any two when filed with the Insurer shall determine the amount of Property Damage. Each appraiser shall be paid by the party selecting him and the expenses of appraisal and of the umpire shall be paid equally by the Member Insured on the one hand and the Insurer on the other.

5. Assignment. Assignment of this Policy or any rights hereunder shall not be valid except with the prior written consent of the Insurer.

6. Choice of Law.

(b) The parties intend that the Insurer conduct its activities so as not to be subject to the insurance regulation of any jurisdiction other than Bermuda NEIL II Policy - October 2006 8

and Delaware. Accordingly, the parties expressly recognize and agree that paragraph (a) above does not evidence an intent by the parties to (i) give jurisdiction over the Insurer to the insurance regulatory authority of any jurisdiction other than Bermuda and Delaware; or (ii) make applicable to this Policy any of the insurance laws or regulations (including those which specify the terms of the by-laws and contracts of mutual insurance companies) of any jurisdiction, including New York, other than to the extent such laws of Bermuda and Delaware are applicable; or (iii) otherwise have the laws of Bermuda or Delaware apply to the construction or enforcement of this Policy.

7. Concealment, Fraud. The Insurer shall have no obligation to make any payments under this Policy if, whether before or after an Accident, any Insured has willfully concealed or misrepresented in writing any material fact or circumstance concerning this insurance or the subject thereof, or the interest of any Insured therein, or in case of any fraud or false swearing by any Insured relating thereto; but the application of this provision shall not affect the Member Insured's obligation to pay the Retrospective Premium Adjustment callable by the Insurer under this Policy.

8. Currency. All payments required to be made under this Policy by the Member Insured or the Insurer shall be made in United States dollars.

9. Dispute Resolution.

(a) The Insurer and the Insured mutually acknowledge that the form, terms and conditions of the Policy have been formulated by representatives of the participating utilities in order to provide insurance coverage which is vital to all participants. It was desired that the Insurer serve as a financially stable and reliable entity,.responsive to the coverage needs of its participants, and providing coverage fairly and equitably as to each Insured, but taking equally into account fairness and equity as to all insureds as a group. While every effort has been made to define with clarity and precision the scope of coverage and other policy provisions, the Insurer and the Insured mutually acknowledge that situations may arise where the terms of the Policy are disputed. For the foregoing reasons, the Insurer and the Insured agree that the following principles shall govern the interpretation of the Policy:

(i) Even-handedness and fairness to both the Insurer and the Insured; (ii) The intentions of the Insurer and the Insured, including any extrinsic evidence of intent; NEIL II Policy - October 2006 9

(iii) The practice of the Insurer and the Insured in interpreting and applying the Policy; (iv) The cooperative rather than adversarial relationship between the Insurer and the Insured; and (v) The contract construction rule of contra proferentem is not applicable to this insurance policy.

(b) The Insurer and Insured agree to endeavor to resolve any dispute between them by means of voluntary proceedings to be agreed upon between them.

In the event of a dispute, either the Insurer or the Insured may request the other to participate in an alternative dispute resolution proceeding. The Insurer and the Insured acknowledge, depending upon the circumstances, that an appropriate proceeding may include but is not limited to one or more of the following: early neutral evaluation, mediation, mini-trial, neutral fact finding, or senior peer review. In the absence of the parties agreeing to participate in an alternative dispute resolution process, the Insurer will agree, at the request of the Insured, to submit the dispute to senior peer review, unless otherwise determined by the Insurer's Board of Directors. The Insurer agrees to pay the fees and expenses of any neutral party associated with the procedures. The use of any such or other proceeding is voluntary to both the Insurer and Insured, but each acknowledges that it is in the best interests of the mutual enterprise to resolve disputes by such voluntary means where possible, and without the need for final and binding arbitration between them.

(c) The Insured and Insurer agree in good faith to consider, in connection with any dispute, the Statement of Dispute Resolution Principles adopted by the Insurer's Board of Directors and Members, as it may be amended from time to time.

(d) Any claim or controversy between the Insured and the Insurer as to any matters arising out of or relating to this Policy, which is not settled between themselves, pursuant to paragraph 9(b) above or otherwise, shall be submitted at the request of either the Insured or the Insurer to arbitration in New York City unless the parties agree as to another location. Arbitration of a dispute is final and binding. The Insured and the Insurer shall try in good faith to agree on the appointment of a sole arbitrator to settle the dispute. In the5event the parties cannot agree on the appointment of a sole arbitrator, they can agree to have a sole arbitrator appointed by the then President of the Association of the Bar of the City of New York or in the absence of agreement to do so, a three-person arbitration panel shall be appointed. In the event that either the Insured or the Insurer determines that the dispute is not appropriate for a sole arbitrator, a three-person arbitration panel shall be appointed. In such NEIL II Policy - October 2006 10

instance, the Insured shall appoint one arbitrator and the Insurer another; the two so appointed shall select the third. If the two arbitrators fail to agree on a third arbitrator for a period of sixty calendar days from the date of appointment of the second arbitrator, then on request of the Insured or the Insurer such third arbitrator shall be selected by the then President of the Association of the Bar of the City of New York. The Insured and the Insurer may by express agreement determine the arbitral procedures to be followed; in the event the parties donot agree, New York law, including the statutory rules on arbitration, shall govern all matters of procedure.

The arbitrators shall first determine the liability of the parties as to the dispute, claim or controversy, and then, only if necessary, determine the type and amount of relief to be granted. The arbitrators shall award reasonable attorney's fees and costs to the prevailing party in such amount as they determine appropriate, not to exceed the amount of fees and costs incurred by the non-prevailing party. For this purpose, the fees incurred shall be calculated at reasonable prevailing hourly billing rates and include all reasonable out-of-pocket expenses.

(e) To the extent that any dispute, claim or controversy between the Insured and the Insurer hereunder is not subject to arbitration for any reason whatever, the United States District Court for the Southern District of New York shall have exclusive jurisdiction thereof. For such purpose, the Insured agrees to accept, without objection to form or manner, service of process by registered mail directed to the person identified in Item 11 of the Declarations.

For such purpose, the Insurer agrees to accept, without objection to form or manner, service of process by regis'tered mail directed to Nuclear Electric Insurance Limited, 1201 Market Street, Suite 1100, Wilmington, Delaware 19801. The foregoing consents to service of process are not intended nor shall they be construed to extend to any dispute, claim, controversy, cause of action, or other matter other than as stated in this paragraph.

10. Errors and Omissions. No inadvertent error, omission or failure in furnishing reports hereunder shall prejudice the Insureds' right of recovery, but shall be corrected when discovered.

11. Headings. The headings in this Policy are inserted for convenience only and shall not be deemed to constitute a part hereof.

12. Inspection and Suspension.

(a) The Insurer shall be permitted, but not obligated, to perform or to have performed on its behalf inspections of the Insured Property at any reasonable time. All inspections and inspection reports made by or on behalf of the Insurer are made solely for insurance purposes. Inspection NEIL II Policy - October 2006 I1I

reports are based upon conditions, practices and property observed and information made available at the time of the inspection, and shall not be deemed to identify all hazards or to indicate that other hazards do not exist. The Insurer and those performing inspections on its behalf shall not be responsible for the correction or control of any conditions, practices or property. Notwithstanding any other agreement, express or implied, to the contrary, neither the right to make an inspection nor the making of an inspection, nor any advice or report resulting therefrom, shall constitute or be construed as an undertaking on behalf of or for the benefit of the Insureds or others to determine or warrant that the facilities, operations or property are safe or healthful, or are in compliance with any law, rule, regulation, procedure or standard.

(b) Upon discovery of a dangerous condition with respect to any machine, vessel, or part thereof a representative of the Insurer may request that such machine, vessel or part thereof be taken out of service without delay so that corrective measures may be instituted.

(c) Upon discovery of a failure to comply with the Insurer's standards with respect to the qualifications of the Member Insured's or Operator's personnel, or operating and maintenance practices, a representative of the Insurer may request that such failures be corrected without delay.

(d) It shall be the obligation of the Insureds to ensure that the Insurer is accorded the right of inspection under paragraph V. 12(a) above and to ensure compliance with any requests by the Insurer pursuant to paragraphs V. 12(b) or V. 12(c). The failure of the Operator to permit the Insurer to inspect or to comply with such a request of the Insurer shall be deemed a breach of this obligation on the part of the Insureds.

(e) If a request made under paragraphs V. 12(b) or V. 12(c) of this subsection is not complied with, a representative of the Insurer may immediately suspend coverage under this Policy with respect to any Accidental Property Damage arising out of any incident which results from such noncompliance, by written notice hai~ded, mailed or delivered to the Member Insured.

(f) The Insurer may suspend coverage under this Policy, in whole or in part, with respect to the Insured Property, without prior notice to the Insureds, if (i) the NRC suspends or revokes for any reason the operating license issued with respect to any Unit on such Insured Property, or (ii) the NRC issues a shutdown order with respect to such Unit, or (iii) the NRC issues a confirmatory order keeping such Unit shut down.

(g) The coverage suspended in accordance with paragraphs V. 12(e) and V. 12(f) may be reinstated by the Insurer, but only by an endorsement issued to form a part of this Policy. The suspension of the coverage under NEIL II Policy - October 2006 12

this Policy shall not affect the obligation of the Member Insured to pay the Retrospective Premium Adjustment 'allable by the Insurer under this Policy.

13. Loss Payments (a) Except as provided in subsection V. 13.(b) below, it is agreed that payment under this Policy shall be made in the following order:

(i) Losses under Nuclear Liability Coverage.

(ii) Losses under Decommissioning Liability Coverage pursuant to Section I1of the Policy.

(iii) Losses under the Debris Removal and Decontamination Coverage, the Property Damage Coverage, and the Functional Total Loss Coverage.

(b) Payment under this Policy may be made with respect to Losses under the Decommissioning Liability Coverage, Debris Removal and Decontamination Coverage, the Property Damage Coverage, and/or Functional Total Loss Coverage prior to completion of indemnification under the Nuclear Liability Coverage only on the condition that the Member Insured attests that:

(i) no proceeds of this Policy in excess of an amount specified by the Insureds, except as provided in a Proof of Loss filed with the Insurer, are needed to discharge the legal obligation or liability of the Insureds to protect the public health and safety following Accidental Property Damage, as required by the Act; and (ii) the payment or use of policy proceeds for Losses under the Decommissioning Liability Coverage, Debris Removal and Decontamination Coverage, the Property Damage Coverage, and/or the Functional Total Loss Coverage does not violate any regulation or order of the NRC.

(c) No payments shall be made pursuant to Section I until (i) all amounts payable under all Underlying Insurance Policies have actually been expended for the types of losses and expenses covered thereunder or designated for the type of expenses covered under paragraph 1.1(a) or II.,

and (ii) at leastthe amount of the Attachment Point has actually been expended for the types of losses and expenses covered under paragraphs 1.1(b) or 1.1(c) or designated for the type of expenses covered under paragraph 1.1(a) hereof.

No amendment to the Primary Underlying Insurance Policy shall increase the Insurer's liability under this Policy without the prior written consent of the Insurer. The granting of such consent shall be wholly within the discretion of the Insurer.

(c) Policy Decisions and Notice. Except as provided in paragraph 16 of Section V of this Policy, all decisions or actions made or taken with respect to this Policy may only be taken or made by the first named Member Insured and all such decisions or actions shall be binding on all Insureds. Such decisions or actions shall include, without limitation, decisions to give or not give notices of accidents, to file or not file proofs of loss and to bring or not bring an action under the dispute resolution provision. No decision or action with respect to this Policy may be made or taken by anyone other than the Ingurer and the first named Member Insured. The first named Member Insured shall be that Member Insured whose name is listed first in Item 1 of the Declarations. The Insurer and the Insureds agree that all communications between them as to any matter arising under or relating to this Policy shall be made as follows:

(i) If to the Insurer: The communication must be sent by the first named Member Insured and must be sent, by facsimile, mail or delivery to the Insurer by the Member Insured's Delaware Representative at the address listed in Item 2 of the Declarations.

(ii) If to the Insureds: The communication must be sent by the Insurer to the first named Member Insured and must be sent, by facsimile, mail or delivery to the address of the Member Insured's Delaware Representative.

Where only partial Proof of Loss has been provided to the Insurer and the Insurer's liability for the Accidental Property Damage is uncontested, the Insurer may, in its sole discretion, make partial payment to the Insured. Nevertheless, the Insurer shall have no obligation to make such partial payment.

(b) With respect to Losses under Section II, payment shall be made within sixty (60) days after the later of the filing by the Member Insured with the Insurer of the Proof of Loss, as provided herein, or filing by the Member Insured of certification that the Insureds have discharged their legal obligation or liability to protect the public health and safety following Accidental Property Damage, as required by the Act, and ascertainment of the Loss is made by written agreement between the Member Insured and the Insurer or the filing of an award as herein provided.

VI. RETROSPECTIVE PREMIUM ADJUSTMENT The Member Insured agrees to pay to the Insurer the Retrospective Premium Adjustment under the terms and conditions hereinafter set forth.

I1. The Insurer may make demand for the Retrospective Premium Adjustment in whole or in one or more parts from time to time, but only to the extent necessary, in the sole discretion of the Board of Directors of the Insurer, to cover Losses incurred by the Insurer under this Policy and all Other Insurance Policies with coverage effective during the Policy Year (specified in Item 3.B of the Declarations).

2. That portion of the Retrospective Premium Adjustment demanded by the Insurer shall be paid to the Insurer by wire transfer or other method acceptable to the Insurer within twenty (20) business days after demand. The Insurer may, without first pursuing any rights it may have against any Delinquent Member, make such number of further demands upon the Member Insured, including any Delinquent Member, for further portions of the Retrospective Premium Adjustment, to be payable twenty (20) business days after demand, as may be needed to obtain Retrospective Premium Adjustment from the Member Insureds of the Insurer under this Policy and all Other Insurance Policies with coverage effective during the Policy Year sufficient, in the sole discretion of the Board of Directors of the Insurer, to cover Losses under this Policy and all Other Insurance Policies with coverage effective during the Policy Year. The fact that the Insurer has received sufficient Retrospective Premium NEIL II Policy - October 2006 20

Adjustment from such Member Insureds shall not bar the Insurer from pursuing the Insurer's rights against any Delinquent Member.

3. When, for any purpose hereunder, it becomes necessary to calculate the obligation of the Member Insured for the Retrospective Premium Adjustment, it will be calculated as follows:

(a) The amount of the Retrospective Premium Adjustment shall be equal to the product of(i) the Multiple selected by the Board of Directors of the Insurer as required to meet Losses under this Policy and all Other Insurance Policies with coverage effective during the Policy Year, times (ii) the Premium, or if such Premium is for a period shorter than a calendar year, such Premium multiplied by a fraction the numerator of which is 365 and the denominator of which is the number of days in the policy period specified in Item 3A of the Declarations.

(b) The Policy Year to which any Retrospective Premium Adjustment relates shall be determined by the Board of Directors of the Insurer at the time it makes the call for such Retrospective Premium Adjustment based on the date of the Accident under this Policy or any Other Insurance Policy giving rise to the obligation which such Retrospective Premium Adjustment is designed to satisfy. The aggregate of all Retrospective Premium Adjustments under this Policy shall not exceed the Retrospective Premium Adjustment set forth in Item 5.B of the Declarations.

(c) Subject to the provisions with respect to calls made in the event of failure to pay by Delinquent Members, the amount of any call for a Retrospective Premium Adjustment hereunder shall bear the same relation to the total Retrospective Premium Adjustment, payable by all Member Insureds of the Insurer under such call as the highest Premium determined under subparagraph (a)(ii) above bears to the aggregate Premiums, used to calculate the total of all such calls, under this Policy and all Other Insurance Policies with coverage effective during the Policy Year.

(d) The obligation of the Member Insured for the Retrospective Premium Adjustment shall be and remain in full force and effect and all the above calculations shall be made without regard to whether or not the Insurer has any obligation to make payments under this Policy or this Policy is canceled or suspended.

4. The Multiple is no higher than the Multiple in any Other Insurance Policy with insurance coverage effective during the Policy Year.

5. The Board of Directors of the Insurer in its sole discretion may adjust downward the Multiple stated in this Policy and any Other Insurance Policy with coverage effective during the Policy Year to a new lower Multiple, and the Retrospective Premium Adjustment callable under this Policy and any such Other Insurance Policy shall be NEIL II Policy - October 2006 21

reduced by a like proportionate amount. No downward adjustment in such Multiple and corresponding adjustment in any such Retrospective Premium Adjustment may be made with respect to any Retrospective Premium Adjustment which has been assigned by the Insurer, or in any Other Insurance Policy with coverage effective during the Policy Year, if the Multiple in any such Other Insurance Policy, after adjustment, would be less than the Multiple, after adjustment, in this Policy, unless a similar downward adjustment is made in the Multiple in this Policy, together with a corresponding adjustment in the Retrospective Premium Adjustment.

6. The liability of the Member Insured shall be limited to the Premium and the Retrospective Premium Adjustment or any unpaid portion thereof due to the Insurer under the terms of this Policy. No Member Insured shall be subject to any contingent liability or be required to pay any dues or assessments in addition to such Premium and Retrospective Premium Adjustment due under this Policy and those due under any Other Insurance Policies as such Member Insured may have with the Insurer.

The liability of the Member Insured for the Retrospective Premium Adjustment for the Policy Year shall cease six (6) years after the end of the Policy Year, unless prior demand is made therefor.

7. It is agreed that the obligation of the Member Insured to pay any Retrospective Premium Adjustment due under any Other Insurance Policy between the Insurer and the Member Insured which terminated on or before the inception date of this Policy is an obligation of the Member Insured under this Policy. It is also agreed that the terms and the amount of such obligation shall be determined by reference to the Other Insurance Policy under which such obligation arose, notwithstanding that such Other Insurance Policy may no longer be in effect.

8. The liability of each Member Insured, if there be more than one, for the Retrospective Premium Adjustment under this Policy shall be several and not joint and in proportion to their respective interests specified in the Declarations.

9. In the event the Insurer has available credit facilities from lenders, the Board of Directors of the Insurer may, in its sole discretion, utilize such facilities to finance Losses incurred by the Insurer under this Policy and all Other Insurance Policies.

The Insurer may assign to the lenders the Insurer's interest in the Retrospective Premium Adjustment, in whole or in part, including, in the event the Insurer defaults on its obligations to such lenders, the right to call such interest assigned. Such assignment may be made and shall only be effective with respect to the financing of those Losses for which the Retrospective Premium Adjustment could be called. In the event any assignment is made, the Insurer shall give prompt notice thereof to the Member Insured. Each Member Insured shall, upon the request of the Insurer, give acknowledgment of its liability for the Retrospective Premium Adjustment to each of the lenders involved.

NUJCLEAR ELECTRIC INSURANCE LIMITED POLICYHOLDER DISCLOSURE NOTICE OF TERRORISM INSURANCE COVERAGE Coverage for acts of terrorism is already included in your current policy. However, under NEIL's Payment for Acts of Terrorism endorsement, your recovery for losses stemming from an act of terrorism might have been limited. You should know that in accordance with the Terrorism Risk Insurance Act of 2002 (the "Act"), as extended on December 22, 2005, under your existing coverage, NEIL's Payment for Acts of Terrorism endorsement would be inapplicable to any losses caused by certified acts of terrorism under the Act and such losses would be partially reimbursed by the United States under a formula established by federal law. Under this formula, the United States pays 90% (85% for the calendar year 2007) of covered terrorism losses exceeding the statutorily established deductible paid by the insurance company providing the coverage, up to an annual national limit. NEIL is neither increasing, nor attributing any portion of, your annual premium for terrorism coverage.
