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

V. CONDITIONS A. Abandonment There shall be no abandonment to the Insurer of any property.

The two (2) appraisers so selected shall first select a competent and disinterested umpire; and failing for fifteen (15) days from the date of selection of the second appraiser to agree upon such umpire, then on request of the Member Insured or the Insurer, such umpire shall be selected by a judge of the United States District Court for the district in which the Insured Property is located. The appraisers shall then appraise the Property Damage, stating separately Replacement Cost and/or the Actual Cash Value of each item; and, failing to agree, shall submit their differences, only, to the umpire.

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 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, or provide other assurances to the Insurer Pursuant to Section VI.2.

Primary -April 1, 2013 13 2013.01.16.11.55.02

G. Dispute Resolution The Insurer and the Insured mutually acknowledge that the form, terms and conditions of the Policy have been formulated by representatives of the companies participating in the mutual enterprise in order to provide insurance coverage which is vital to all participants. It is 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, or the interpretation of the terms, 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) In the event of an ambiguity in a policy provision, the intentions of the Insurer and the Insured shall be considered by the Arbitrator(s). Evidence of such intentions is limited to the following extrinsic evidence: reports, notes, meeting minutes, and related materials produced by or given to the Insurer's Board of Directors, Advisory Committees, and Task Forces, and any testimony taken from a present or former employee of the Insurer, member of a Member Advisory Committee, or Director; (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 (construing a contract against the drafter) is not applicable to this insurance policy.

2. The Insurer and Insured will endeavor to resolve any dispute between them by means of a voluntary process to be agreed upon between them, including, without limitation, early neutral evaluation, mediation, mini-trial, neutral fact finding, or senior peer review. Neither the Insurer nor the Insured may be compelled to participate in any such voluntary process except that, at the request of an Insured, the Insurer agrees to submit the dispute to senior peer review. The Insurer agrees to pay the fees and expenses of any neutral party associated with the use of any process hereunder. Senior peer review is a process in which both sides present their arguments and view of the evidence to a panel of five (5) employees of other NEIL Members, unless the Insured and Insurer agree that a panel of three (3) would be more appropriate. The panel will provide a written non-binding opinion Primary-April 1, 2013 14 2013.01.16.11.55.02

on the merits of the dispute. Though not an exclusive list, panel members may include individuals from NEIL's Member Representatives, Board of Directors, Member Advisory Committees, or Members' Legal Counsel. None of the panelists may be employed by a Member that is an affiliate of the Insured involved in the dispute. The panelists shall be selected by agreement of the Insured and Insurer, but if no agreement is reached within 30 days of the date the senior peer review is requested, the Insurer and Insured shall each submit a list of five names and a NEIL outside Director (as chosen by the Chairman of the Board) shall select the panelists. The panel, with input from the parties, shall establish a schedule for the proceeding, including, if appropriate, the submittal of written materials and oral arguments.

3. 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, shall not create any rights or obligations on the parties but shall be used as guidelines for conducting dispute resolution processes hereunder.

4. Any dispute, controversy or claim between the Insurer and the Insured as to any matter arising out of or relating to this Policy, or the breach, termination or invalidity thereof, which is not settled between themselves, pursuant to paragraph 2 above or otherwise, shall be settled by arbitration in accordance with the United Nations Commission on International Trade Law's (UNCITRAL) Arbitration Rules. Arbitration of a dispute is final and binding.

a. The number of arbitrators shall be one, unless the Insured or the Insurer (

requests a three-person panel, in which case the number of arbitrators shall be three.

b. In the event the arbitration is to be decided by a single arbitrator, and the parties cannot agree on the appointment of that arbitrator within sixty (60) days of the notice of arbitration being served, the sole arbitrator shall be selected by the appointing authority specified in paragraph 4.d.

c. In the event the arbitration is to be decided by three arbitrators, the Insured shall appoint one arbitrator and the Insurer another; the two so appointed arbitrators shall select the third, who will act as the Chairman for the panel. The party which files the notice of arbitration shall include in such notice the identity of its party-appointed arbitrator. Within forty-five (45) days of service of the notice of arbitration, the second party shall notify the party that filed the notice of arbitration of the identity of its party-appointed arbitrator. At the time of the notification of the appointment, each side shall provide the other with a detailed curriculum vitae for the selected arbitrator, which shall include information regarding any potential conflict of interest of the selected arbitrator, including any financial or personal interest in the result of the arbitration or any past or present relationship with the parties or their representatives. All arbitrators shall Primry-pril1, 01315 213.1.1611.5.0 Primary -April 1, 2013 15 2013.01.16.11.55.02

be obligated to update his/her potential conflict of interest information throughout the arbitration. If (i) the party filing the notice of arbitration fails to include the identity of its party-appointed arbitrator, or (ii) the second party does not notify the first party of its party-appointed arbitrator within forty-five (45) days of service of the notice of arbitration, or (iii) the two party-appointed arbitrators fail to agree on a third arbitrator within a period of sixty (60) days from the date of appointment of the second arbitrator, then, on request of either party, the missing party-appointed arbitrator or the third arbitrator (as the case may be) shall be selected by the appointing authority specified in paragraph 4.d. There shall be no ex parte communications between a party and any of the arbitrators, except that a party-appointed arbitrator shall be permitted to communicate with the party that appointed him/her concerning (1) the identity of the Chairman and (2) issues associated with arbitrator invoices.

d. The appointing authority shall be the American Arbitration Association

("AAA") in New York, New York. The AAA shall select arbitrators from the panel of international arbitrators for the International Centre for Dispute Resolution, the international division of the AAA (the "ICDR Roster"). The arbitrators selected from the ICDR Roster shall be U.S.

nationals. If for any reason the AAA fails to appoint an arbitrator within thirty (30) days of the date of receipt of the request for such appointment, either party may proceed pursuant to Article 75 of the Civil Practice Law and Rules of the State of New York and make application to the Supreme Court of the State of New York, County of New York for the appointment of the arbitrator.

e. To the extent there is any inconsistency between the UNCITRAL Arbitration Rules and the provisions of this Policy, the latter shall govern.

f. The place of the arbitration shall be New York, New York, unless the parties agree upon another location.

g. Within forty-five (45) days after the appointment of the Chairman, the arbitrators shall conduct an initial conference to which the parties will be invited to attend. At the initial conference, the parties and arbitrators shall discuss, without limitation, (1) the procedures to be followed, (2) scheduling of submissions and hearings, and (3) a timetable for discovery.

At a minimum, the discovery order shall require the parties to provide each other non-privileged documents that are requested by the other side and that reasonably relate to the claims and defenses asserted in the arbitration. Following the initial conference, the arbitrators shall issue a Procedural Order to the parties setting forth the procedures and schedule.

h. Within sixty (60) days of the close of the hearings (or the later of post-hearing oral argument or post-hearing written submissions should the Primary- April 1, 2013 16 2013.01.16.11.55.02

arbitrators authorize them), the arbitrators shall issue their award, which shall be in writing and shall present a detailed statement of the factual and legal bases for the award. The award of the arbitrators shall require a majority of two votes. 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. In no case may the arbitrators order the rescission or reformation of this Policy.

Further, unless the arbitrators determine that it is inappropriate under the circumstances of the case, the award shall provide that post-award interest shall begin to accrue at the rate of the Prime Rate, as published in the Wall Street Journal as of the date of the award, plus two (2) percent per annum from the date sixty (60) days after the award is delivered to the parties until the date the award is paid.

The arbitrators shall award reasonable attorney's fees and costs to the prevailing party, 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 hourly billing rates and shall include all reasonable out-of-pocket expenses, including, without limitation, the reasonable costs of expert witnesses and consultants. If the Insured has retained counsel on a contingency fee basis, and the Insurer is the prevailing party, the arbitrators shall award the Insurer all of its reasonable attorney's fees and costs (without consideration of the fees and costs incurred by the Insured). (

j. In the event the award is challenged in court and the challenge is denied, the party that challenged the award shall pay the reasonable attorney's fees and costs incurred by the non-challenging party in defending against the challenge to the award.

k. The parties acknowledge that any dispute resolution proceeding is intended to be confidential and therefore agree to properly maintain and not disclose or reveal any information obtained from the other party pursuant to the terms of a Confidentiality Agreement to be executed between the parties at the beginning of the proceeding (the terms of which shall be determined by the arbitrators in the event that the parties are unable to agree). In the case of arbitration, the written decision of the arbitrator(s) shall be available to other Insureds of NEIL and ONEIL, except that any information within the written decision that the Insured can show is proprietary in nature will be redacted.

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, or to the extent that applicable law otherwise permits the parties to seek provisional relief from the courts prior to the time that the arbitral panel is appointed, the United States District Court for the Southern District of New York (or the Supreme Court of the Primary- April 1,2013 17 2013.01.16.11.55.02

State of New York, New York County, if federal jurisdiction cannot be attained) 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 or form of overnight mail 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, or overnight mail, directed to the Insurer's General Counsel, at 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.

I. Evaluations and Compliance with Loss Control Standards I1. The Insurer shall be permitted, but not obligated, to perform or to have performed on its behalf, evaluations of the Insured Property at any reasonable time. All evaluations and evaluation reports made by or on behalf of the Insurer are made solely for insurance purposes. Evaluation reports are based upon the conditions, practices and property observed and information made available at the time of the evaluation, and shall not be deemed to identify all hazards or to indicate that other hazards do not exist. The Insurer and those performing evaluations 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 evaluation nor the making of an evaluation, 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. It shall be the obligation of the Insureds to ensure that the Insurer is accorded the right to conduct an evaluation under this paragraph.

2. Notwithstanding the provisions in Paragraph V.1.5, upon discovery of a dangerous condition (the "Dangerous Condition) with respect to any property, or part thereof, insured under this Policy (the "Affected Property"), whether discovered as a result of an evaluation or otherwise, a representative of the Insurer may (a) request that the Affected Property be taken out of service without delay, and/or (b) request that actions be taken to remedy the Dangerous Condition.

Primary- April 1, 2013 18 2013.01.16.11.55.02

3. If a request made under Paragraph V.1.2 is not complied with, the Insurer may immediately suspend coverage as to the Affected Property and/or as to Property Damage that could have been avoided or reduced had the Dangerous Condition been remedied, provided, however, that there will be coverage for Property Damage if the Insured can demonstrate that the Property Damage was unrelated to the failure to take the requested action (and there is otherwise coverage under this Policy). Notice of the suspension (which may be made together with either request referred to in Paragraph V.1.2) shall be written and, notwithstanding any other provisions under this Policy, may be sent to the Member Insured by hand delivery, e-mail, fax or courier.

4. It shall be an obligation under this Policy that the Insured comply with the Shall Requirements contained in the Insurer's Loss Control Standards.

5. When the Insurer learns of an Insured's failure to comply with, or to take agreed upon actions to correct a failure to comply with, a Shall Requirement contained in the Insurer's Loss Control Standards, the Insurer may notify the Insured of the non-compliance, and upon or after such notification shall have the right to (a) adjust the Insured's premiums ("Premium Adjustments") and/or the Insured's deductible ("Deductible Adjustments"), and/or (b) suspend coverage under this policy as to the property that is the subject of the applicable Shall Requirement and/or as to Property Damage that could have been avoided or reduced if not for the Insured's failure to comply with the applicable Shall Requirement, provided, however, that there will be coverage for Property Damage if the Insured can demonstrate that the Property Damage was not related to the noncompliance (and there is otherwise coverage under this Policy).

The Actions referred to in this Paragraph may be collectively referred to as "Policy Adjustments".

6. Notification to the Insured about a non-compliance with the Shall Requirements contained in the Insurer's Loss Control Standards shall be in writing (the "Notification Letter") and, notwithstanding any other provisions under this Policy, may be sent to the Member Insured by hand delivery, e-mail, fax or courier. The date of the Notification Letter shall be referred to as the "Notification Date". The Notification Letter shall set forth the specific Premium Adjustments and Deductible Adjustments to be made, which shall be assessed in accordance with the schedules contained in the Insurer's Rating Procedures and Schedules then in effect. Deductible Adjustments shall apply in accordance with the details set forth in the Notification Letter.

7. Unless indicated otherwise in the Notification Letter, all Premium and Deductible Adjustments will take effect on the 31 st calendar day after the Notification Date Primary- April 1,2013 19 2013.01.16.11.55.02

unless the Insured requests a variance (in accordance with the procedures contained in the Loss Control Standards) or requests that the applicable coverage be removed because the Insured has elected not to comply with the relevant Loss Control Standard requirement. The precise scope of any coverage removal will be described in an endorsement to the Policy.

8. Unless indicated otherwise in the Notification Letter, all Premium and Deductible Adjustments will remain in effect until the Insurer endorses the Policy to remove such Policy Adjustments. For purposes of determining whether an Accident took place during a period that there was a Deductible Adjustment, the relevant date is the date on which the Accident actually occurred and not any deemed date that may otherwise be defined in the Policy.

9. Notwithstanding the provisions in Paragraph V.1.6 any suspension of coverage under Paragraphs V.1.3 and V.1.5 shall be in accordance with the scope of coverage suspension set forth in writing and delivered to the Insured.

10. If the Insured requests a variance, no Premium or Deductible Adjustments will be implemented while the variance request is being considered by the Insurer. If the Insurer does not grant the variance, the Premium and Deductible Adjustments shall be applied retroactively to the day the Adjustments would have gone into effect under Paragraph V.1.7, even if the Insured requests a review or otherwise appeals the Insurer's decision. The provisions of this paragraph will apply even in the event that an Accident actually occurs during the time that the variance request is being considered.

11. The Insurer may immediately suspend coverage under this Policy, in whole or in part, with respect to the Insured Property 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. In the event that the Insurer chooses to suspend coverage under this provision, it shall notify the Member Insured in writing of that decision.

12. The coverage suspended in accordance with Paragraphs V.1.3 and V.1.5 above, as well as the coverage removed under Paragraph V.1.7 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 will not affect the obligation of the Member Insured to pay the Retrospective Premium Adjustment callable by the Insurer under this Policy, or provide other assurances to the Insurer Pursuant to Section VI.2.

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 Primary- April 1, 2013 20 1-013.01.16.11.55.02

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

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. I 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.

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.

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. The Insurer, in the sole discretion of the Board of Directors, may require the Member Insured to provide assurance to the Insurer of the Member Insured's ability to satisfy its obligation to pay a Retrospective Premium Adjustment when called. Within twenty (20) business days of receiving notice from the Insurer that such assurance is required, the Member Insured shall notify the Insurer of the option selected to provide the required assurance, which will include, but is not limited to, providing a letter of credit, providing a financial guarantee, purchasing retrospective premium insurance, or paying a Deposit Premium, and implement such option by providing the Insurer with the required documentation or payment, depending on the option selected. The parameters for a letter of credit, a financial guarantee, and the retrospective premium insurance options will be provided to the Member Insured by the Insurer at the time the Insurer requires the Member Insured to take the action. The terms regarding the Deposit Premium are set forth in Paragraph 3 below.

(

Primary- April 1,2013 27 2013.01 o6.11.55.02

3. If the Member Insured elects to pay a Deposit Premium, the Insurer may require the Deposit Premium to be paid in whole, in part, or in parts. Any Deposit Premium paid to the Insurer will be returned to the Member Insured when, in the sole discretion of the Insurer's Board of Directors, the retention of the Deposit Premium is no longer required. The amount of any Deposit Premium paid shall be a credit against the obligation of the Member Insured to pay a call made for a Retrospective Premium Adjustment and, to the extent thereof, shall be treated as a payment of the Retrospective Premium Adjustment as of the date a call for a Retrospective Premium Adjustment is made. Amounts paid as Deposit Premiums will be held in an interest bearing account and, until such a call is made, interest earned on the Deposit Premium amount will be paid back to the Member Insured on an annual basis, within ninety (90) business days after the end of the applicable calendar year. However, if the Member Insured fails to elect one of the options available pursuant to Paragraph 2 within the time frame required, or at any other time when in the sole discretion of the Insurer's Board of Directors it is in the best interests of the Insurer, the Insurer may make demand upon the Member Insured for a Deposit Premium, whether or not a demand for a Deposit Premium is made upon any other Member Insured(s). If a demand is made by the Insurer, the Member Insured shall pay the Deposit Premium within twenty (20) business days of demand.

4. 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.

5. 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 plus any Additional Premium, or if such is for a period Primary- April 1,2013 28 2013.01.16.11.55.02

shorter than a calendar year, such Premium and Additional 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 plus Additional Premium determined under subparagraph (a)(ii) above bears to the aggregate Premiums plus Additional 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.

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

(a) The amount of the Deposit Premium, if required, shall be equal to Retrospective Premium Adjustment listed in Item 5.B of the Declarations, unless otherwise indicated.

(b) The aggregate of the Deposit Premium and any Retrospective Premium Adjustments callable under this Policy shall not exceed the Retrospective Premium Adjustment set forth in Item 5.B of the Declarations.

(c) The amount of the Deposit Premium maybe adjusted at the anniversary of this Policy.

(

Primary-April 1,2013 29 2013.01.16.11.55.02

(d) The obligation of the Member Insured for the Deposit Premium 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.

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. The liability of the Member Insured shall be limited to the Premium, Additional Premium the Retrospective Premium Adjustment or any unpaid portion thereof due to the Insurer under the terms of this Policy, and any assurance that may be required pursuant to Section VI.2. No Member Insured shall be subject to any contingent liability or be required to pay any dues or assessments in addition to such Premium, Additional Premium, Retrospective Premium, and any assurance under Section VI.2. Adjustment due under this Policy and those due under any Other Insurance Policies as such Member Insured mayhave 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.

10. 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.

11. The liability of each Member Insured, if there be more than one, for the Retrospective Premium Adjustment, and any assurance that may be required pursuant to Section VI.2, under this Policy shall be several and not joint and in proportion to their respective interests specified in the Declarations.

Primary- April 1, 2013 30 2013.01.16.11.55.02

12. 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.

NUCLEAR ELECTRIC INSURANCE LIMITED POLICYHOLDER DISCLOSURE NUCLEAR POLICY RENEWALS NOTICE OF TERRORISM INSURANCE COVERAGE EFFECTIVE DECEMBER 26, 2007 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 could be limited by the terms of the endorsement. However, in accordance with the Terrorism Risk Insurance Program Reauthorization Act of 2007, which took effect December 26, 2007, (TRIPRA), NEIL's Payment for Acts of Terrorism endorsement would not cap the damages for any "certified" acts of terrorism under TRIPRA.

You are hereby notified that under TRIPRA, the definition of act of terrorism has changed. As defined in Section 102(1), the term "act of terrorism" means any act that is certified by the Secretary of the Treasury - in concurrence with other specified federal officials - to be an act of terrorism; to be a violent act or an act that is dangerous to human life, property, or infrastructure; to have resulted in damage within the United States, or outside the United States in the case of certain air carriers or vessels or the premises of a United States mission; and to have been committed by an individual or individuals as part of an effort to coerce the civilian population of the United States or to influence the policy or affect the conduct of the United States Government by coercion.

Under your coverage, any losses resulting from certified acts of terrorism may be partially reimbursed by the United States Government under a formula established in TRIPRA. Your policy may contain other exclusions which might affect your coverage. Under the formula, the United States Government generally reimburses 85% of covered terrorism losses exceeding the statutorily established deductible paid by the insurance company providing the coverage.

TRIPRA, contains a $100 billion cap that limits U.S. Government reimbursement as well as insurers' liability for losses resulting from certified acts of terrorism when the amount of such losses exceeds $100 billion in any one calendar year. If the aggregate insured losses for all insurers exceed $100 billion, any insurer that has met its deductible will not be liable to pay for any losses in excess of the $100 billion sustained by its insureds. Thus, if the $100 billion cap is reached, your coverage may be reduced.

NEIL is neither increasing, nor attributing any portion of, the annual premium for terrorism coverage, but a surcharge might be added to the premium if, after a certified act of terrorism, the federal Department of Treasury requires a recoupment of certain amounts paid by the federal government in accordance with the terms of TRIPRA.

I. Resources Available The Insureds' maximum recovery for all such Losses under this Policy and all Nuclear Insurance Policies and Builders' Risk Policies shall be an aggregate of:

(b) If such Property Losses for all Insureds exceed the amount determined under paragraph I above, the Insured's maximum recovery shall be the amount determined under paragraph I 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 and Builders' Risk 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.

3. Declarations Page Nothing herein shall be construed to entitle the Insured to recover more than the amount of the Policy Limits stated in Item 6 of the Declarations.

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. The first Accidental Property Damage caused by an Act of Terrorism that occurs after this or any other twelve-month period shall trigger a new twelve-month period.

I. DECONTAMINATION LIABILITY AND EXCESS PROPERTY COVERAGE

1. The Insurer 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, provided such expenses would otherwise be covered under paragraphs 1.1(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 as part of the loss at least $100,000,000 of Nuclear Liability Coverage; (ii) is covered under paragraphs I. 1of the Policy or would 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 for the Functional Value of the Unit following Accidental Property Damage.

(b) If the Member Insured elects to receive the Functional Value of the Unit the Member will not be entitled to receive any additional recovery under the Property Damage Coverage of the Policy.

(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.

NEIL II - April 1, 2013 2 2013.02.08.14.07.47

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.

5. (a) The Insurer shall be liable hereunder, whether or not an Underlying Insurance Policy provides coverage for Accidental Property Damage caused by:

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 companies participating in the mutual enterprise in order to provide insurance coverage which is vital to all participants. It is 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, or the interpretation of the terms, are disputed. For the foregoing reasons, the Insurer and the Insured agree that the following principles shall govern the interpretation of the Policy:

(1) Even-handedness and fairness to both the Insurer and the Insured; (2) In the event of an ambiguity in a policy provision, the intentions of the Insurer and the Insured shall be considered by the Arbitrator(s).

Evidence of such intentions is limited to the following extrinsic evidence: reports, notes, meeting minutes, and related materials produced by or given to the Insurer's Board of Directors, Advisory Committees, and Task Forces, and any testimony taken from a present or former employee of the Insurer, member of a Member Advisory Committee, or Director; (3) The practice of the Insurer and the Insured in interpreting and applying the Policy; (4) The cooperative rather than adversarial relationship between the Insurer and the Insured; and (5) The contract construction rule of contra proferentem (construing a contract against the drafter) is not applicable to this insurance policy.

b) The Insurer and Insured will endeavor to resolve any dispute between them by means of a voluntary process to be agreed upon between them, including, without limitation, early neutral evaluation, mediation, mini-trial, neutral fact finding, or senior peer review. Neither the Insurer nor the Insured may be compelled to participate in any such voluntary process except that, at the request of an Insured, the Insurer agrees to submit the dispute to senior peer NEIL 11 - April 1, 2013 9 2013.02.08.14.07.47

review. The Insurer agrees to pay the fees and expenses of any neutral party associated with the use of any process hereunder. Senior peer review is a process in which both sides present their arguments and view of the evidence to a panel of five (5) employees of other NEIL Members, unless the Insured and Insurer agree that a panel of three (3) would be more appropriate. The panel will provide a written non-binding opinion on the merits of the dispute.

Though not an exclusive list, panel members may include individuals from NEIL's Member Representatives, Board of Directors, Member Advisory Committees, or Members' Legal Counsel. None of the panelists may be employed by a Member that is an affiliate of the Insured involved in the dispute. The panelists shall be selected by agreement of the Insured and Insurer, but if no agreement is reached within 30 days of the date the senior peer review is requested, the Insurer and Insured shall each submit a list of five names and a NEIL outside Director (as chosen by the Chairman of the Board) shall select the panelists. The panel, with input from the parties, shall establish a schedule for the proceeding, including, if appropriate, the submittal of written materials and oral arguments.

c) 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, shall not create any rights or obligations on the parties but shall be used as guidelines for conducting dispute resolution processes hereunder.

d) Any dispute, controversy or claim between the Insurer and the Insured as to any matter arising out of or relating to this Policy, or the breach, termination or invalidity thereof, which is not settled between themselves, pursuant to paragraph 2 above or otherwise, shall be settled by arbitration in accordance with the United Nations Commission on International Trade Law's (UNCITRAL) Arbitration Rules. Arbitration of a dispute is final and binding.

(1) The number of arbitrators shall be one, unless the Insured or the Insurer requests a three-person panel, in which case the number of arbitrators shall be three.

(2) In the event the arbitration is to be decided by a single arbitrator, and the parties cannot agree on the appointment of that arbitrator within sixty (60) days of the notice of arbitration being served, the sole arbitrator shall be selected by the appointing authority specified in paragraph 9.d(4).

(3) Inthe event the arbitration is to be decided by three arbitrators, the Insured shall appoint one arbitrator and the Insurer another; the two so appointed arbitrators shall select the third, who will act as the Chairman for the panel. The party which files the notice of arbitration shall include in such notice the identity of its party-appointed arbitrator. Within forty-five (45) days of service of the NEIL 1I - April 1, 2013 10 2013.02.08.14.07.47

notice of arbitration, the second party shall notify the party that filed the notice of arbitration of the identity of its party-appointed arbitrator. At the time of the notification of the appointment, each side shall provide the other with a detailed curriculum vitae for the selected arbitrator, which shall include information regarding any potential conflict of interest of the selected arbitrator, including any financial or personal interest in the result of the arbitration or any past or present relationship with the parties or their representatives. All arbitrators shall be obligated to update his/her potential conflict of interest information throughout the arbitration. If (i) the party filing the notice of arbitration fails to include the identity of its party-appointed arbitrator, or (ii) the second party does not notify the first party of its party-appointed arbitrator within forty-five (45) days of service of the notice of arbitration, or (iii) the two party-appointed arbitrators fail to agree on a third arbitrator within a period of sixty (60) days from the date of appointment of the second arbitrator, then, on request of either party, the missing party-appointed arbitrator or the third arbitrator (as the case may be) shall be selected by the appointing authority specified in paragraph 9.d(4). There shall be no exparte communications between a party and any of the arbitrators, except that a party-appointed arbitrator shall be permitted to communicate with the party that appointed him/her concerning (1) the identity of the Chairman and (2) issues associated with arbitrator invoices.

(4) The appointing authority shall be the American Arbitration Association ("AAA") in New York, New York. The AAA shall select arbitrators from the panel of international arbitrators for the International Centre for Dispute Resolution, the international division of the AAA (the "ICDR Roster"). The arbitrators selected from the ICDR Roster shall be U.S. nationals. If for any reason the AAA fails to appoint an arbitrator within thirty (30) days of the date of receipt of the request for such appointment, either party may proceed pursuant to Article 75 of the Civil Practice Law and Rules of the State of New York and make application to the Supreme Court of the State of New York, County of New York for the appointment of the arbitrator.

(5) To the extent there is any inconsistency between the UJNCITRAL Arbitration Rules and the provisions of this Policy, the latter shall govern.

(6) The place of the arbitration shall be New York, New York, unless the parties agree upon another location.

(7) Within forty-five (45) days after the appointment of the Chairman, the arbitrators shall conduct an initial conference to which the parties NEIL II - April 1, 2013 I1I 2013.02.08.14.07.47

will be invited to attend. At the initial conference, the parties and arbitrators shall discuss, without limitation, (1) the procedures to be followed, (2) scheduling of submissions and hearings, and (3) a timetable for discovery. At a minimum, the discovery order shall require the parties to provide each other non-privileged documents that are requested by the other side and that reasonably relate to the claims and defenses asserted in the arbitration. Following the initial conference, the arbitrators shall issue a Procedural Order to the parties setting forth the procedures and schedule.

(8) Within sixty (60) days of the close of the hearings (or the later of post-hearing oral argument or post-hearing written submissions should the arbitrators authorize them), the arbitrators shall issue their award, which shall be in writing and shall present a detailed statement of the factual and legal bases for the award. The award of the arbitrators shall require a majority of two votes. 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. In no case may the arbitrators order the rescission or reformation of this Policy. Further, unless the arbitrators determine that it is inappropriate under the circumstances of the case, the award shall provide that post-award interest shall begin to accrue at the rate of the Prime Rate, as published in the Wall Street Journal as of the date of the award, plus two (2) percent per annum from the date sixty (60) days after the award is delivered to the parties until the date the award is paid.

(9) The arbitrators shall award reasonable attorney's fees and costs to the prevailing party, 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 hourly billing rates and shall include all reasonable out-of-pocket expenses, including, without limitation, the reasonable costs of expert witnesses and consultants. If the Insured has retained counsel on a contingency fee basis, and the Insurer is the prevailing party, the arbitrators shall award the Insurer all of its reasonable attorney's fees and costs (without consideration of the fees and costs incurred by the Insured).

(10) In the event the award is challenged in court and the challenge is denied, the party that challenged the award shall pay the reasonable attorney's fees and costs incurred by the non-challenging party in defending against the challenge to the award.

(11) The parties acknowledge that any dispute resolution proceeding is intended to be confidential and therefore agree to properly maintain and not disclose or reveal any information obtained from the other NEIL II - April 1, 2013 12 2013.02.08.14.07.47

party pursuant to the terms of a Confidentiality Agreement to be executed between the parties at the beginning of the proceeding (the terms of which shall be determined by the arbitrators in the event that the parties are unable to agree). In the case of arbitration, the written decision of the arbitrator(s) shall be available to other Insureds of NEIL and ONEIL, except that any information within the written decision that the Insured can show is proprietary in nature will be redacted.

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, or to the extent that applicable law otherwise permits the parties to seek provisional relief from the courts prior to the time that the arbitral panel is appointed, the United States District Court for the Southern District of New York (or the Supreme Court of the State of New York, New York County, if federal jurisdiction cannot be attained) 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 or form of overnight mail 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, or overnight mail, directed to the Insurer's General Counsel, at 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.

12. Evaluations and Compliance with Loss Control Standards (a) The Insurer shall be permitted, but not obligated, to perform or to have performed on its behalf, evaluations of the Insured Property at any reasonable time. All evaluations and evaluation reports made by or on behalf of the Insurer are made solely for insurance purposes. Evaluation reports are based upon the conditions, practices and property observed and information made available at the time of the evaluation, and shall not be deemed to identify all hazards or to indicate that other hazards do not exist. The Insurer and those performing evaluations on its behalf shall not be responsible for the correction or control of any conditions, practices or property.

neither the right to make an evaluation nor the making of an evaluation, 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. It shall be the obligation of the Insureds to ensure that the Insurer is accorded the right to conduct an evaluation under this paragraph.

whether discovered as a result of an evaluation or otherwise, a representative of the Insurer may (1) request that the Affected Property be taken out of service without delay, and/or (2) request that actions be taken to remedy the Dangerous Condition.

(c) If a request made under Paragraph V. 12.b is not complied with, the Insurer may immediately suspend coverage as to the Affected Property and/or as to Property Damage that could have been avoided or reduced had the Dangerous Condition been remedied, provided, however, that there will be coverage for Property Damage if the Insured can demonstrate that the Property Damage was unrelated to the failure to take the requested action (and there is otherwise coverage under this Policy).

(e) If the Insurer learns of an Insured's failure to comply with, or to take agreed upon actions in accordance with the agreed upon Resolution Plan to correct a failure to comply with, a SHALL Requirement contained in the Insurer's Loss Control Standards, and, as a result and in accordance with the terms of a Primary Policy issued by the Insurer for the Site insured under this Policy the Insurer suspends coverage under that Primary Policy, such suspension of coverage shall apply with equal force and effect to this Policy.

(a) 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).

(b) The Insurer, in the sole discretion of the Board of Directors, may require the Member Insured to provide assurance to the Insurer of the Member Insured's ability to satisfy its obligation to pay a Retrospective Premium Adjustment when called. Within twenty (20) business days of receiving notice from the Insurer that such assurance is required, the Member Insured shall notify the Insurer of the option selected to provide the required assurance, which will include, but is not limited to, providing a letter of credit, providing a financial guarantee, purchasing retrospective premium insurance, or paying a Deposit Premium, and implement such option by providing the Insurer with the required documentation or payment, depending on the option selected. The parameters for a letter of credit, a financial guarantee, and the retrospective premium insurance options will be provided to the Member Insured by the Insurer at the time the Insurer requires the Members Insured to take the action. The terms regarding the Deposit Premium are set forth in Paragraph (c) below.

(c) If the Member Insured elects to pay a Deposit Premium, the Insurer may require the Deposit Premium to be paid in whole, in part, or in parts. Any Deposit Premium paid to the Insurer will be returned to the Member Insured when, in the sole discretion of the Insurer's Board of Directors, the retention of the Deposit Premium is no longer required. The amount of any Deposit Premium paid shall be a credit against the obligation of the Member Insured to pay a call made for a Retrospective Premium Adjustment and, to the extent thereof, shall be treated as a payment of the Retrospective Premium Adjustment as of the date a call for a Retrospective Premium Adjustment is made. Amounts paid as Deposit Premiums will be held in an interest bearing account and, until such a call is made, interest earned on the Deposit Premium amount will be paid back to the Member Insured on an annual basis, within ninety (90) business days after the end of the applicable calendar year. However, if the Member Insured fails to elect one of the options available pursuant to Paragraph (b) within the time frame required, or at any other time when in the sole discretion of the Insurer's Board of Directors it is in the best interests of the Insurer, the Insurer may make demand upon the Member Insured for a Deposit Premium, whether or not a demand for a Deposit Premium is made upon any other Member Insured(s).

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.

(e) 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:

(2) 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.

(3) 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 plus Additional NEIL II - April 1, 2013 24 2013.02.08.14.07.47

Premium determined under subparagraph (a)(ii) above bears to the aggregate Premiums plus Additional 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.

(4) 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.

(f) When, for any purpose hereunder, it becomes necessary to calculate the obligation of the Member Insured for the Deposit Premium, it will be calculated as follows:

(1) The amount of the Deposit Premium, if required, shall be equal to Retrospective Premium Adjustment listed in Item 5.B of the Declarations, unless otherwise indicated.

(2) The aggregate of the Deposit Premium and any Retrospective Premium Adjustments callable under this Policy shall not exceed the Retrospective Premium Adjustment set forth in Item 5.B of the Declarations.

(3) The amount of the Deposit Premium may be adjusted at the anniversary of this Policy.

(4) The obligation of the Member Insured for the Deposit Premium 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.

(h) 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 1I - April 1,2013 25 2013.02.08.14.07.47

NUCLEAR ELECTRIC INSURANCE LIMITED POLICYHOLDER DISCLOSURE NUCLEAR POLICY RENEWALS NOTICE OF TERRORISM INSURANCE COVERAGE EFFECTIVE DECEMBER 26, 2007 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 could be limited by the termns of the endorsement. However, in accordance with the Terrorism Risk Insurance Program Reauthorization Act of 2007, which took effect December 26, 2007, (TRIPRA), NEIL's Payment for Acts of Terrorism endorsement would not cap the damages for any "certified" acts of terrorism under TRIPRA.

You are hereby notified that under TRIPRA, the definition of act of terrorism has changed. As defined in Section 102(1), the term "act of terrorism" means any act that is certified by the Secretary of the Treasury - in concurrence with other specified federal officials - to be an act of terrorism; to be a violent act or an act that is dangerous to human life, property, or infrastructure; to have resulted in damage within the United States, or outside the United States in the case of certain air carriers or vessels or the premises of a United States mission; and to have been committed by an individual or individuals as part of an effort to coerce the civilian population of the United States or to influence the policy or affect the conduct of the United States Government by coercion.

Under your coverage, any losses resulting from certified acts of terrorism may be partially reimbursed by the United States Government under a formula established in TRIPRA. Your policy may contain other exclusions which might affect your coverage. Under the formula, the United States Government generally reimburses 85% of covered terrorism losses exceeding the statutorily established deductible paid by the insurance company providing the coverage.

TRIPRA, contains a $100 billion cap that limits U.S. Government reimbursement as well as insurers' liability for losses resulting from certified acts of terrorism when the amount of such losses exceeds $100 billion in any one calendar year. If the aggregate insured losses for all insurers exceed $100 billion, any insurer that has met its deductible will not be liable to pay for any losses in excess of the $100 billion sustained by its insureds. Thus, if the $100 billion cap is reached, your coverage may be reduced.

NEIL is neither increasing, nor attributing any portion of, the annual premium for terrorism coverage, but a surcharge might be added to the premium if, after a certified act of terrorism, the federal Department of Treasury requires a recoupment of certain amounts paid by the federal government in accordance with the terms of TRIPRA.
