The Premium shall be paid to the Insurer by wire transfer or other method acceptable to the Insurer on or before the beginning of the policy period specified in Item 3A of the Declarations.

2. As a condition precedent to the Insurer's obligations under this Policy, the Member Insured agrees to notify the Insurer that the Insured Property has been classified Category Number Five by the Institute of Nuclear Power Operations ("INPO"),

3. The Member Insured further agrees to pay the Insurer the Retrospective Premium Adjustment under the terms and conditions specified under Section VI.

C. Assignment Assignment or transfer of this Policy shall not be valid except with the prior written consent of the Insurer.

D. Choice of Law

1. In view of the diverse locations of the parties hereto and the desirability of unified regulation, the Insureds and Insurer agree that the terms of this Policy shall determine their respective rights and duties and that this Policy shall be construed and enforced in accordance with and governed by the internal law of the State of New York, United States of America.

2. 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 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.

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 NEIL Primary Property, October 1, 2001 10

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 I1. There shall be deducted from the amount of each and every Loss the Deductible stated in Item 9 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.

2. In the event the Loss at any location exceeds fifty percent (50%) of the amount of insurance applicable to such location under this Policy, this Deductible Clause shall not 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.

NEIL Primary Property, October 1,2001 11

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 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.

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 NEIL Primary Property, October 1, 2001 12

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.

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 1200, 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.

NElL Primary Property, October 1, 2001 13

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.

3. 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.

4. 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.

NEIL Primary Property, October 1, 2001 14

K. Limits

1. The Insurer shall not be liable for more than the amount shown as limit of liability in the Declarations for any one Accident.

2. The insurance provided by this Policy shall not be reduced by the sum paid for any one Accident.

3. 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

1. 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

1. 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 NEIL Primary Property, October 1, 2001 15

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 deemed to be a single Flood.

3. Earthquake or Volcanic Eruption Loss Each earthquake shock or volcanic eruption shall be deemed a separate Loss; provided that if more than one earthquake shock or volcanic eruption shall occur within any period of seventy-two (72) hours commencing during the term of this Policy and such earthquake shocks or volcanic eruptions have a common origin or are caused by a single incident, then such earthquake shocks or volcanic eruptions shall be deemed to be a single earthquake or volcanic eruption.

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 effected, 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. 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:

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 courier to the address listed in Item 1 of the Declarations or to the address of such Member Insured's Delaware Representative. It shall be the obligation of the first named Member Insured to communicate the contents of any notification from the Insurer to the other Member Insureds.

The Insured's compliance with the provisions of this paragraph is a condition precedent to the Insurer's obligations under this Policy.

P. Policy Modifications This Policy embodies all agreements between the Member Insured and the Insurer or any of their agents relating to this insurance. There shall be no change in the terms, provisions and stipulations of this Policy except in writing hereon or by endorsement added hereto by the Insurer and the Member Insured.

1. The Insureds shall give or cause to be given to the Insurer immediate written notice of any Accidental Property Damage and shall make efforts to protect the Insured Property from further damage. The Insureds shall separate or cause to be separated, with reasonable promptness, the damaged and undamaged Insured Property, put it in the best possible order, furnish a complete inventory of the destroyed, damaged and undamaged Insured Property, showing in detail quantities, costs, the replacement cost and estimated amount of Loss claimed.

2. Within twelve (12) months after the Accidental Property Damage, unless such time is extended in writing by the Insurer, not to be unreasonably withheld, the Insureds shall render to the Insurer a proof of loss ("Proof of Loss"), in the form approved by the Insurer, signed and sworn to by the Member Insured, stating the knowledge and belief of the Insureds as to the time and origin of the Accidental Property Damage, the interest of the Insureds and all others in the Insured Property, the value of the Insured Property involved in the Accident, the amount of Loss or damage thereto, all other contracts of insurance, whether valid or not, covering any of said Insured Property, and (a) with respect to Losses covered under Section I.A. 1, an attestation by the Member Insured that either no proceeds of this Policy, or no proceeds of this Policy in excess of the Specified Nuclear Liability Amount, except as provided in a Proof of Loss filed with the Insurer, are needed to discharge the legal obligation or liability of the Insureds under the Act to protect the public health and safety following Accidental Property Damage, and that the payment of policy NEIL Primary Property, October 1, 2001 17

proceeds for the Property Damage under Section I.A.1 does not violate any regulation or order of the NRC; and (b) with respect to Losses covered under Section I.A.2, the time and origin of the Accidental Property Damage necessitating such expenses, the amount of expenses incurred in discharging the Insureds' legal obligation or liability under the Act to protect the public health and safety following Accidental Property Damage, and an attestation by the Member Insured as to the Insurer's legal obligation or liability to incur such expenses.

3. The Insureds shall exhibit or cause to be exhibited to any person designated by the Insurer, as often as may be reasonably required, all that remains of any Insured Property and shall submit to examinations under oath by any person named by the Insurer, and shall subscribe the same. The Insureds shall, as often as may be reasonably required, produce for examination all books of accounts, bills, invoices and other vouchers, or certified copies thereof if originals be lost, or other documents needed by the Insurer to determine its liability, at such reasonable time and place as may be designated by the Insurer or its representatives, and shall permit extracts and copies thereof to be made.

R. State Premium Tax The Insureds represent that they have paid or will pay any applicable state premium tax.

S. Subrogation Except as provided in paragraph 3 below, the Insurer may require from the Insureds an assignment of all right of recovery against any party for Accidental Property Damage to the extent that payment therefor is made by the Insurer, and the Insureds shall execute and deliver all necessary instruments and do all things necessary or desirable on behalf of the Insurer to secure such rights. The Insureds shall take no action after the Accident which may prejudice the Insurer's rights under this paragraph; however, prior to an Accident, the Insureds may waive in writing any or all right of recovery against any party for Accidental Property Damage.

2. The Insurer hereby waives any right of subrogation acquired by reason of any payment under this Policy arising out of any Accidental Property Damage against the Insureds and any party furnishing services, materials, parts, or equipment in connection with the planning, construction, maintenance, operation or use of the Insured Property.

3. It is a condition of this Policy that the Insureds shall repay to the Insurer any recoveries made by the Insureds on account of any Accidental Property Damage to the extent that the Insurer would have been entitled to such recoveries had this waiver not been included in this Policy. The proceeds of any recovery shall be applied first to any uncompensated Property Damage incurred by the Insureds, NEIL Primary Property, October 1,2001 18

including reimbursement of any deductible amount under this Policy, and then, to the extent any proceeds of such recovery remain, to reimburse the Insurer for any payments made by it to the Insureds.

NEIL Primary Property, October 1, 2001 19

5. Neither the cancellation of the Policy on the part of the Member Insured or the Insurer, nor its automatic termination, shall affect the obligation of the Member Insured to pay the Retrospective Premium Adjustment callable by the Insurer under this Policy.

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 such 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 ofthe 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.

2. The value of Insured Property in transit at the time of an Accident shall be the replacement cost of such Insured Property, but not exceeding the amount which it would cost to repair or replace such Insured Property with material of like kind and quality within a reasonable time after such loss, including general average and salvage charges.

3. In the event of Property Damage to Insured Property constituting nuclear fuel, the Insurer's obligation to indemnify the Insureds and their legal representatives under Section I shall be limited as follows:

(a) Beginning with the date initial criticality is achieved at a Unit, the value of the nuclear fuel in such Unit shall be deemed to be equal to the value of a full fuel core of the fuel then in such unit reduced to reflect the proportion of the usable bum up consumed; and (b) Spent nuclear fuel shall have no value and the Insurer shall have no obligation to indemnify the Insureds or their legal representatives for any Property Damage thereto.

NEIL Primary Property, October 1, 2001 20

W. Waiver Provisions No provision, stipulation or forfeiture shall be held to be waived by any requirement or proceeding on the part of the Insurer relating to appraisal or to any examination provided for herein.

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.A 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:

NEIL Primary Property, October 1, 2001 21

(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 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 NEIL Primary Property, October 1, 2001 22

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.

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 NEIL Primary Property, October 1, 2001 23

Policy agrees to be subject to and bound by the obligations and duties of membership.

It shall be the obligation of the Member Insured to ensure the exercise of due diligence and dispatch by the Operator and the failure of the Operator to exercise such due diligence and dispatch shall be deemed a breach of this obligation on the part of the Member Insured.

(c) Any delay in the Unit's resumption of the generation of electric power other than for testing purposes which results from Accidental Property Damage occurring during an Outage shall constitute a separate Outage and shall be subject to a separate Deductible Period; provided, however, that any such delay which occurs during an Outage and which results from Accidental Property Damage occurring while Insured Property is in transit to or from the Unit shall not constitute a separate Outage if the property damaged or destroyed was needed to repair or replace other property, the damage to or destruction of which caused the existing Outage.

2. For an Outage of a Unit covered hereunder, after expiration of the Deductible Period, the Insurer shall pay to the Insureds or their designated payee for each week of the Outage following such Deductible Period 100 percent of the Weekly Indemnity for such Unit each week for six weeks.

3. (a) In the event of an Outage of more than one Unit by reason of the same Accident, the maximum Weekly Indemnity per unit shall be limited as follows:

Number of Units Simultaneously Out of Service Per Unit Indemnity 1 100% of single unit recovery 2 80% of single unit recovery 3 60% of single unit recovery NEIL Primary Property, October 1, 2001

4 50% of single unit recovery (b) Upon start-up of an affected Unit, the limitations on Weekly Indemnity payments, if still applicable, will apply only to those remaining affected Units.

II. PREMIUM AND RETROSPECTIVE PREMIUM ADJUSTMENT

1. The Member Insured agrees to pay to the Insurer the Premium and the Retrospective Premium Adjustment under the terms and conditions hereinafter set forth.

2. The Premium shall be paid to the Insurer by wire transfer or other method acceptable to the Insurer on or before the beginning of the policy period specified in Item 3 of the Declarations. This Policy shall not become effective until the Premium has been paid and the Member Insured has received written notice from the Insurer that all other conditions for coverage have been satisfied. The Insurer shall give the Member Insured prompt notice of its execution of this Policy and of its acceptance or rejection of any payments made hereunder.

3. The Member Insured agrees that if INPO rates the Insured Property as not meeting the industry standard of acceptable performance (such as by classification in INPO's Category Number Five or any successor thereto), the Insurer may increase the Premium due under this NEIL II, October 1, 2001 5

Policy by up to twenty-five percent (25%) on an annualized basis and that Items 6 and 7B of the Declarations shall be amended accordingly. Such increase in Premium shall be effective from the date the Insured Property is classified Category Number Five and shall apply only during the period of time that the Insured Property remains classified Category Number Five. As a condition precedent to the Insurer's obligations under this Policy, the Member Insured further agrees to notify the Insurer that the Insured Property has been classified Category Number Five by INPO within seven (7) days of being advised by INPO of such classification being put in place, and to pay such additional Premium due hereunder to the Insurer by wire transfer or other method acceptable to the Insurer within twenty (20) business days after demand.

4. 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.

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

6. When for any purpose hereunder it becomes necessary to calculate the obligation of the Member Insured for a 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.

(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 on the basis of 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 7B of the Declarations.

(c) Subject to the provisions of subsection 11.5 with respect to calls made in the event of failure to pay by Delinquent Members, the amount of any call for a Retrospective NEIL II,October 1, 2001 6

Premium Adjustment hereunder shall bear the same relation to the total Retrospective Premium Adjustment, payable by all Member Insureds of the Insurer, under this Policy and all Other Insurance Policies with coverage effective during the Policy Year, under such call as the Premium referred to in subparagraph II.6(a)(ii) 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 any payment under this Policy or this Policy is canceled or suspended.

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

8. 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.

9. (a) 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 Policy 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.

(b) 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.

NEIL II, October 1, 2001 7

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

III. RIGHT TO ASSIGN RETROSPECTIVE PREMIUM ADJUSTMENT 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 be effective only 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.

IV. 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 Insurer's Memorandum of Association or the Bye-Laws increase the amount of Premium or Retrospective Premium Adjustment payable or callable hereunder.

V. DECONTAMINATION LIABILITY AND EXCESS PROPERTY COVERAGE

1. The Insurer, in consideration of the Premium and the Retrospective Premium Adjustment, and subject to the provisions and stipulations herein or added hereto, agrees to indemnify the Insureds and their legal representatives (a) for all expenses necessarily incurred by 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, caused by any Accident covered under the Primary Underlying Insurance Policy; provided such expenses would otherwise be covered under paragraphs V. 1(b) and/or V. 1(c) hereof, but for this paragraph V. 1(a);

NEIL II,October 1, 2001 8

(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 occurring under the Primary Underlying Insurance Policy; which, except as provided in subsection V.7 hereof, would be covered by such Primary Underlying Insurance Policy if the limit of the Primary Underlying Insurer's liability thereunder were not exhausted, but only to the extent that the amount of Accidental Property Damage exceeds $500,000,000 and the Attachment Point has been reached.

2. (a) In the event of Accidental Property Damage which (i) exceeds

$500,000,000 and includes Nuclear Liability Coverage; (ii) is covered under paragraphs V. 1(a),

(b) or (c) of the Policy or would be covered under such paragraphs 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 (c) hereof for the Functional Value of the undamaged Functional Property following Accidental Property Damage.

(b) 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 V.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.

(c) 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, as a condition of the Insurer's liability under this subsection V.2, the Insureds shall self-insure not less than the amount determined by multiplying the Functional Value of the undamaged Functional Property by the percentage specified in Item 8A of the Declarations. The Insurer's liability shall be calculated by multiplying the total Functional Value of the undamaged Functional Property by the percentage specified in Item 8B of the Declarations.

(d) The Member Insured shall promptly notify the Insurer in the event that any of the Units specified in Item 10 of the Declarations or in the Declarations of the Primary Underlying Insurance Policy is to permanently cease operations prior to the scheduled expiration of such Unit's operating license.

(e) In the event of Accidental Property Damage which (i) exceeds

$1,000,000,000 and includes Nuclear Liability Coverage; (ii) is covered under paragraphs V. 1(a),

(b) or (c) of the Policy or would be covered under such paragraphs but for the availability of insurance under the Underlying Insurance Policies; and (iii) results in permanent cessation of nuclear operations at a Unit, the Insureds may, at any time after the preceding requirements are satisfied, elect to be indemnified for Actual Cash Value rather than Functional Value. In the event of such election, the applicable coverage for Actual Cash Value shall be determined by NEIL II, October 1, 2001 9

replacing the words "Actual Cash Value" for "Functional Value" in paragraphs (a) and (c) hereof and Section VII.9 of the Policy.

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. Except as provided in subsection V.5 below, it is agreed that payment under this Policy shall be made in the following order:

(a) Losses under Nuclear Liability Coverage.

(b) Losses under Decommissioning Liability Coverage pursuant to Section VI of the Policy.

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

5. (a) 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.

(b) Except as provided in paragraph V.5(c) 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, and/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 of Decontamination Liability, Decommissioning Liability and Excess Property Insurance Requested, as specified in Item 5 of the Declarations, as such amount may be reduced pursuant to the terms of this Policy.

NELL II, October 1,2001 10

(c) At the request of the Insureds, the amount calculated in accordance with paragraph V.5(b) 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.

(b) For purposes of this Policy, except where the Underlying Insurance Policies are written on an Actual Cash Value basis, the value of the Insured Property at the time of an Accident shall be the Replacement Cost of such Insured Property, but only if such Insured Property as is damaged or destroyed is replaced with identical or like kind property on the same premises and intended for the same occupancy and use, and used in connection with a nuclear facility. In all other cases, the value of the Insured Property at the time of the Accident shall be the Actual Cash Value of such Insured Property as is damaged or destroyed, notwithstanding that the Policy may refer to the Replacement Cost of such Insured Property.

7. (a) The Insurer shall be liable hereunder, whether or not the Primary Underlying Insurer is liable, for Accidental Property Damage caused by:

(i) Windstorm, tornado or hurricane; (ii) Flood, including flood caused by or resulting from hurricane, tornado or windstorm; surface water, waves, tidal water, or tidal wave, overflow of streams or other bodies of water, or spray from any of the foregoing, all whether driven by wind or not, and release of water impounded by a dam at any location specified in the Underlying Insurance Policies (each of which is deemed a "Flood"); and NEIL HI,October 1, 2001 11

(iii) Earthquake, volcanic eruption, landslide, subsidence or sinking of land or other earth movement, settlement or other movement of foundations, at any locations specified in the Underlying Insurance Policies.

(b) Accidental Property Damage by windstorm, tornado or hurricane, Flood, or earthquake or volcanic eruption shall constitute a single claim hereunder; provided, that (i) if more than one windstorm, tornado or hurricane should occur within any period of forty-eight hours commencing during the term of this Policy, and such windstorms, tornados or hurricanes have a common origin or are caused by a single Accident, then such windstorms, tornados or hurricanes shall be deemed to be a single windstorm, tornado or hurricane within the meaning hereof; (ii) if more than one Flood should occur within any period of ninety six 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 deemed to be a single Flood within the meaning hereof; and (iii) if more than one earthquake shock or volcanic eruption shall occur within any period of seventy-two hours commencing during the term of this Policy and such earthquake shocks or volcanic eruptions have a common origin or are caused by a single Accident, then such earthquake shocks or volcanic eruptions shall be deemed to be a single earthquake or volcanic eruption within the meaning hereof.

8. In the event that Accidental Property Damage under this Policy and under one or more Other Insurance Policies with insurance coverage effective during the Policy Year is caused directly or indirectly by any single Accident which is either listed in subparagraphs V.7(a)(i), (ii) or (iii) hereof, or which involves radioactive contamination, or by any Accident which ensues directly or indirectly from an Accident listed in subparagraphs V.7(a)(i), (ii) or (iii) hereof or from an Accident involving radioactive contamination, the Insureds agree that:

(a) The Insurer's liability for all such Accidental Property Damage shall not exceed the greater of (A) the Amount of Decontamination Liability, Decommissioning Liability and Excess Property Insurance Requested, as stated in Item 5 of the Declarations, or (B) the highest of the Amount of Decontamination Liability, Decommissioning Liability and Excess NElL II,October 1, 2001 12

Property Insurance Requested stated in the Declarations of the Other Insurance Policies providing coverage with respect to the same Accident.

9. Notwithstanding any other provision in this Policy, the Insurer shall not be liable for any sums, which the Insured may be obligated to pay as damages:

(a) because of bodily injury or personal injury; or (b) because of damage to property not described in the Declarations, or covered by the Underlying Insurance Policies; or (c) for which the Insured is covered or would be entitled to coverage under a nuclear energy liability policy issued by American Nuclear Insurers, Nuclear Energy Liability Insurance Association, Mutual Atomic Energy Liability Underwriters or other third party liability insurer or other third party entity.

NEIL II, October 1, 2001 13

Notwithstanding any other provision in this Policy, the Insurer's liability under this Policy shall not exceed the Amount of Decontamination Liability, Decommissioning Liability and Excess Property Insurance Requested, as stated in Item 5 of the Declarations.

(b) The Insurer hereby waives any right of subrogation acquired by reason of any payment under this Policy arising out of any Accidental Property Damage covered hereunder against the Insureds and any party furnishing services, materials, parts, or equipment in connection with the planning, construction, maintenance, operation or use of the Insured Property.

(c) It is a condition of this Policy that the Insureds shall repay the Insurer any recoveries made by the Insureds on account of any Accidental Property Damage to the extent that the Insurer would have been entitled to such recoveries had this waiver not been included in this Policy; provided, however, the proceeds of any such recovery shall be applied first to any uncompensated Property Damage incurred by the Insureds, including reimbursement of any deductible amount under this Policy, and then, to the extent any proceeds of such recovery remain, to reimburse the Insurer for any payments made by it to the Insureds.

15. 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.

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.
