1.

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

2.

(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 l.l(c) hereof, but for this paragraph l.l(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.

(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. lofthe Policy or would be covered under that paragraph but for the availability of insurance under the Underlying Insurance Policies; and (iii) causes 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.

Except as provided in paragraph I.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 I.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:

(a)

(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.

(i)

Windstorm, tornado or hurricane; (ii)

Flood, including flood caused by 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 (iii)

2017.01.15.17.08.48

(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 ninety-six 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 ninety-six 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.

( c)

The Insurer is liable hereunder only to the extent that the amount of Accidental Property Damage exceeds the Attachment Point.

6.

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 by any single Accident which is either listed in paragraph 1.5 hereof, or which involves radioactive contamination, or by any Accident which is caused by an Accident listed in paragraph 1.5 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 Blanket Limit, as stated in Item 6 of the Declarations, or (B) the highest of the Amount of Decontamination Liability, Decommissioning Liability and Excess Property Insurance Requested, as stated in the Declarations of the Other Insurance Policies, or (C) the sum of Decontamination Liability, Decommissioning Liability and Excess Property Insurance Requested, as stated in the Declarations of the Other Insurance Policies, plus the Amount of Blanket Limit, as stated in Item 6 of the Declarations providing coverage with respect to the same Accident.

Whole Layer Blanket - April 1, 2017 BX17-007 5

2017.01.15.17.08.48

(b)

The Insurer's liability under this Policy shall be the amount determined under paragraph 1.6(a) above times a fraction, the numerator of which is the Insurer's liability for the Accidental Property Damage under this Policy but for this subsection 1.6, and the denominator of which is the sum of the Insurer's liability for the Accidental Property Damage under this Policy and all Other Insurance Policies, but for this subsection.

7.

Notwithstanding any other provision of this Policy, the Insurer's liability under this Policy shall be the amount payable to the Insureds, but for this provision, less any amount owed to the Insurer by the Insureds, including any Retrospective Premium Adjustment due under this Policy, due under any Other Insurance Policy as such Member Insured may have with the Insurer, or referred to in subsection VI(f).

3.

(b)

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

For the foregoing reasons, the Insurer and the Insured agree that the following principles shall govern the interpretation of the Policy:

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 Whole Layer Blanket - April 1, 2017 BX17-007 10 2017.01.15.17.08.48

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)

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 Whole Layer Blanket - April 1, 2017 BX17-007 11 2017.01.15.17.08.48

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 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.

(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 ofreceipt of the request for such appointment, either party may proceed pursuant to Article 75 of the Civil Practice Law and Rules of the State ofNew York and make application to the Supreme Court of the State ofNew York, County of New Yark for the appointment of the arbitrator.

(5)

To the extent there is any inconsistency between the UNCITRAL 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 Whole Layer Blanket-April 1, 2017 BX17-007 12 2017.01.15.17.08.48

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 Whole Layer Blanket - April I, 2017 BX17-007 13 2017.01.15.17.08.48

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 registereq 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.

11.

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

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.

Notwithstanding any other agreement, express or implied, to the contrary, Whole Layer Blanket-April 1, 2017 BX17-007 14 2017.01.15.17.08.48

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.

(b)

Notwithstanding the provisions in Paragraph V.12( e ), upon discovery of a dangerous condition (the "Dangerous Condition) with respect to any property, or part thereof, insured under this Policy or a Primary Policy issued by the Insurer for Site insured under this Policy (the "Affected Property"),

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. l 2(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). Notice of the suspension (which may be made together with either request referred to in Paragraph V. l 2(b) 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.

(d)

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

(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. The Insurer shall notify the Insured of a suspension of coverage under this Policy in the same notice sent by the Insurer concerning suspension under the Primary Policy. Upon reinstatement of coverage under the Primary Policy, coverage shall be reinstated under this Policy in accordance with the provisions of Paragraph (i) of this Section.

Whole Layer Blanket - April 1, 2017 BX17-007 15 2017.01.15.17.08.48

(f)

If the Insured requests that coverage be removed under a Primary Policy issued by the Insurer for the Site insured under this Policy, such removal of coverage shall have equal effect under this Policy, with the precise scope of such removal to be described in an endorsement to this Policy or as set forth in writing and delivered to the Insured.

(g)

Any suspension of coverage under Paragraphs V.12(c) and V.12(e) of this policy shall be in accordance with the scope of coverage suspension set forth in writing and delivered to the Insured.

(h)

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.

(i)

The coverage suspended in accordance with Paragraphs V.12(c) and V.12(e) above, as well as any coverage removed, 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 Vl(b ).

13.

The granting of such consent shall be wholly within the discretion of the Insurer.

When Loss Payable.

(a)

With respect to Losses under paragraph I. I and I.2(a), the amount 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, as herein Whole Layer Blanket - April 1, 2017 BX17-007 23 2017.01.15.17.08.48

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

(b)

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

VI.

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

(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 Whole Layer Blanket-April 1, 2017 BX17-007 24 2017.01.15.17.08.48

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). If a demand is made by the Insurer, the Member Insured shall pay the Deposit Premium within twenty (20) business days of demand.

(d)

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.

(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:

(I)

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 shorter than a calendar year, such Premium and Additional Premium multiplied by a fraction the numerator of which is 365 and the Whole Layer Blanket - April 1, 2017 BX17-007 25 2017.01.15.17.08.48

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

(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 Premium determined under subparagraph (e)(l)(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, ifrequired, 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.

Whole Layer Blanket-April 1, 2017 BX17-007 26 2017.01.15.17.08.48

(g)

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

(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.

(i)

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(b). 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(b )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.

G)

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.

(k)

The liability of each Member Insured, ifthere 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.

(1)

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 Whole Layer Blanket - April 1, 2017 BX17-007 27 2017.01.15.17.08.48

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.

NUCLEAR ELECTRIC INSURANCE LIMITED POLICYHOLDER DISCLOSURE NUCLEAR POLICY RENEWALS NOTICE OF TERRORISM INSURANCE COVERAGE EFFECTIVE JANUARY 8, 2015 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 2015, which took effect January 8, 2015, (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 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 caused by 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, for the 2015 calendar year, the United States Government generally reimburses 85% of covered terrorism losses exceeding the statutorily established deductible paid by the insurance company providing the coverage. This amount will be decreased on a phased in basis, at a rate of 1 % per year, from 2016 to 2020, with the end result being that the United States Government will reduce reimbursement to 80% of covered terrorism losses for the year 2020. TRIPRA contains a $100 billion cap that limits U.S. Government reimbursement as well as insurers' liability for losses caused by 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 ofTRIPRA.

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 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).

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 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.

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 Primary-April 1, 2017 P17-075 16 2017.01.23.21.22.11

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 ofNew York and make application to the Supreme Court of the State ofNew 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.

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

Within forty-five (45) days after the appointment of the Chairman, the arbitrators shall conduct an initial conference to which the parties will be Primary - April I, 2017 Pl7-075 17 2017.01.23.21.22.11

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 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.

(i)

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).

G)

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 Primary - April I, 2017 P17-075 18 2017.01.23.21.22.11

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 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 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.

Primary - April 1, 2017 Pl7-075 19 2017.01.23.21.22.11

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.

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 ifthe 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 lnsured'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 Primary - April 1, 2017 Pl 7-075 20 2017.01.23.21.22.11 I

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 31st calendar day after the Notification Date 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.I.6 any suspension of coverage under Paragraphs V.I.3 and V.I.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.I.7, even ifthe 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.

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.

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, ifthe Member Insured fails to elect one of the options Primary - April 1, 2017 P17-075 29 2017.01.23.21.22.11

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 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.

Primary - April 1, 2017 P17-075 30 2017.01.23.21.22.11

( 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 Additibnal 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, ifrequired, 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 may be adjusted at the anniversary of this Policy.

(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 Primary-April 1, 2017 P17-075 31 2017.01.23.21.22.11

Adjustment which has been assigned by the Insurer, or in any Other Insurance Policy with coverage effective during the Policy Year, ifthe 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 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.

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 Vl.2, under this Policy shall be several and not joint and in proportion to their respective interests specified in the Declarations.

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.

NUCLEAR ELECTRIC INSURANCE LIMITED POLICYHOLDER DISCLOSURE NUCLEAR POLICY RENEWALS NOTICE OF TERRORISM INSURANCE COVERAGE EFFECTIVE JANUARY 8, 2015 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 2015, which took effect January 8, 2015, (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 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 caused by 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, for the 2015 calendar year, the United States Government generally reimburses 85% of covered terrorism losses exceeding the statutorily established deductible paid by the insurance company providing the coverage. This amount will be decreased on a phased in basis, at a rate of 1 % per year, from 2016 to 2020, with the end result being that the United States Government will reduce reimbursement to 80% of covered terrorism losses for the year 2020. 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 TRIP RA.

NUCLEAR ELECTRIC INSURANCE LIMITED WILMINGTON, DELAWARE NEIL I ACCIDENTAL OUTAGE INSURANCE POLICY POLICY NO. El 7-075-2 This Policy is made by and among the Member Insured (specified in Item 1 of the Declarations) and Nuclear Electric Insurance Limited, a Bermuda mutual company with limited liability (the "Insurer").

The Insurer is only licensed in Bermuda and Delaware and the Insureds (those Insureds specified in Item 9 of the Declarations together with the Member Insured) will not be protected by the guaranty funds of any U.S. jurisdiction.

The Member Insured will be required to execute the Policy in Delaware. The Policy will become effective only upon the acceptance by the Member Insured of the delivery of the Policy at the Insurer's office in Delaware.

I.

INSURING AGREEMENT In consideration of the premium paid, and subject to the terms and conditions of this Policy, the Insurer agrees to pay the Member Insured, after the expiration of the Deductible Period, the amounts hereinafter specified in the event of an Outage at a Unit specified in the Declarations caused by Accidental Property Damage to Insured Property on site or while Insured Property is in transit to or from the Unit.

In Witness Whereof, the Insurer and the Member Insured have caused this Policy to be executed and attested on their behalf in Wilmington, Delaware.

INSURER:

Wilmington, Delaware Nuclear Electric Insurance Limited Wilmington, Delaware Date:

As of April 1, 2017 Witn"" J:jfl, A,11 iku, k~

NEIL I -April 1, 2017 El7-075-2 By' ~B~~:t MEMBER INSURED:

STP Nuclear Operating Company 2017.01.23.21.13.04

A.

Coverage for Accidental Property Damage at the Unit This Policy provides insurance for an Outage at a Unit specified in the Declarations caused by Accidental Property Damage occurring to Insured Property.

B.

Transit Coverage This Policy also provides insurance for an Outage at a Unit specified in the Declarations caused by Accidental Property Damage occurring while Insured Property is in transit to or from the Unit, subject to the limit and Deductible Period shown in the Declarations and the following terms and conditions:

1.

For purposes of this coverage, Insured Property includes property that has been purchased for use at the Unit and is in transit to the Unit.

2.

This coverage applies only shipments oflnsured Property worldwide except for loss or damage in any country that is listed as an embargoed or restricted destination within Part 110 of Chapter 10 of the U.S. Code of Federal Regulations (10 C.F.R. § 110) or is listed as a country requiring specific authorization within Part 810 of Chapter 10 of the U.S. Code of Federal Regulations (10 C.F.R. §810).

No coverage is provided for any shipment beyond 100-nautical miles of the shores of the country of origin or destination for airborne or waterborne shipments, except when the point of exit and entry for the shipment is to be the same country in which case this coverage will remain in effect throughout the shipment.

3 It is a condition of insurance that the Insured Property be packed and shipped in accordance with all applicable laws or regulations having the force of law.

Additionally, the Insured is required to use all reasonable means to save and preserve the Insured Property at and after an Accident or when the Insured Property is in danger of physical damage.

Notwithstanding the foregoing, the Insurer shall not be liable under Sections I.A and LB with respect to any Outage unless the Outage is caused by Accidental Property Damage.

C.

Outage Duration

1.

A Cessation Outage shall be deemed to commence at midnight of the day the Unit ceases generating electric power. A Delay Outage shall be deemed to commence at midnight of the first day on which the Unit could have resumed the generation of electric power but for such Accidental Property Damage. An Outage shall be deemed to end at midnight of the day on which with the exercise of due diligence and dispatch by the Member Insured the Unit could resume generating electric power other than for testing purposes. This provision contemplates the Outage ending when the Unit's generator main breaker is closed, synchronizing the Unit NEIL I-April 1, 2017 E17-075-2 2

2017.01.23.21.13.04

with the electrical grid. At that point, electricity is being generated for commercial purposes. The phrase "other than for testing purposes" is not intended to extend an Outage until all testing is completed. It is intended to extend the Outage to the point where the electricity being generated is used for purposes other than testing purposes.

2.

In the event a Unit needs to be shutdown following synchronization to effect repairs for damage directly related to the original Accident, but which were not identifiable until the Unit was restarted, these additional shutdown periods would be indemnifiable as an extension of the original Outage. In any event, no payments will be made for the days of generation when the Unit is synchronized to the grid. 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.

3.

Any delay in the Unit's resumption of the generation of electric power other than for testing purposes which is caused by Accidental Property Damage not related to the cause of an Outage, whether occurring prior to or during an Outage, shall constitute a separate Outage and shall be subject to a separate Deductible Period; provided, however, that any such delay which is caused by Accidental Property Damage occurring while Insured Property, or property that has been purchased for use at this Unit, 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. For the purpose of this section only, "in transit" shall include from when the Insured Property to be repaired is removed until it is reinstalled after repairs, or until the property purchased to replace the Insured Property is installed.

D.

Payment of Weekly Indemnity I.

Subject to the terms and conditions of this Policy, the Insurer shall pay to the Insureds or their designated payee for each week of the Outage following the Deductible Period the following amounts:

a.

100 percent of the Weekly Indemnity for such Unit each week for the First Payment Period as shown in Item 6B of the Declarations; then

b.

80 percent of the Weekly Indemnity for such Unit each week for the Second Payment Period as shown in Item 6B of the Declarations; and thereafter

c.

80 percent of the Weekly Indemnity for such Unit each week for the Third Payment Period as shown in Item 6B of the Declarations.

NEIL I -April l, 2017 El7-075-2 3

2017.01.23.21.13.04

d.

Subject to subsection D.1.e below, in the event an Outage of a Unit covered hereunder extends past the Planned Shutdown Date, the Weekly Indemnity for such extended period shall be 10% of the Weekly Indemnity for the Unit specified in Item 6A of the Declarations.

e.

The 10% limitation on Weekly Indemnity payments referred to in subsection D. l.d above shall not apply if:

(1) the Accident that caused the Property Damage which caused the Outage requires the payment of at least $100,000,000 of the coverage provided under one or both of the following:

a.

Section I.A.2 of the Primary Property and Decontamination Liability Insurance Policy issued with respect to the site where the Unit(s) insured under this Policy are located

b.

Section 1.1 of the Decontamination Liability, Decommissioning Liability and Excess Property Insurance Policy issued with respect to the site where the Unit(s) insured under this Policy are located (2)

The Accident that caused the Property Damage which caused the Outage causes permanent cessation of nuclear operations at a Unit, and (3)

The NRC or the U.S. Secretary of Energy determines that there has been an Extraordinary Nuclear Occurrence as defined in the Atomic Energy Act of 1954.

2.

The Member Insured shall promptly notify the Insurer in the event that any of the Units specified in Item 7 of the Declarations is to permanently cease operations prior to the scheduled expiration of such Unit's operating license.

E.

Net Present Value Payment The Member Insured may request from the Insurer payment of the net present value of the total amount payable yet unpaid in accordance with Section I.D.l(c), subject to the following conditions and subject to the approval of the Insurer, which approval may be withheld for any reason:

1.

The Member Insured relinquishes all rights to any future payment under Section I.D.l(c);

2.

The net present value of the amount indicated in Section I.D.1 ( c) shall be determined utilizing a discount rate equal to the percentage representing the NEIL I -April 1, 2017 El 7-075-2 4

2017.01.23.21.13.04

average annual fixed income investment return, excluding liquid reserves, of the Insurer's investment account for the twenty (20) quarters preceding the request, or 3%, whichever is greater.

3.

In the event the Outage ceases prior to the expiration of the Third Payment Period, the Insured shall repay to the Insurer, within sixty (60) days following conclusion of such Outage, the amount received under this Section LE times a fraction, the numerator of which shall be the number of days remaining in the Third Payment Period and the denominator of which shall be the total number of days in the Third Payment Period; and

4.

At the time that an Insured makes a request for a net present value payment under the provision of this Section LE, the Insured shall be required to complete the Accidental Outage Claims Adjustment Form, as part of the Proof of Loss filing, in order to determine the Weekly Indemnity amount to be used in the Policy. The Weekly Indemnity amount determined with that Proof of Loss filing will be used for the entire period of time for which a net present value payment is sought under this paragraph.

F.

Limitations on Payment I.

The Insurer's obligation to pay the Weekly Indemnity shall terminate when the Outage has ended. Payments for partial weeks of an Outage shall be prorated. In no event shall the Insurer be liable for more than the Limit of Liability specified in Item 6A of the Declarations.

2.

In the event of an Outage of more than one Unit by reason of the same Accident, the Weekly Indemnity per Unit shall be limited as follows:

Number of Units Simultaneously Out of Service 1

2 3

4 Per Unit Indemnity (Percent of Selected Recovery) 100% of single unit recovery 80% of single unit recovery 60% of single unit recovery 50% of single unit recovery Upon start-up of an affected Unit, the limitations on Weekly Indemnity payments, if still applicable, will apply only to those remaining affected Units.

NEIL I -April 1, 2017 E17-075-2 5

2017.01.23.21.13.04

G.

Non-Nuclear Outage The Insurer's liability under this Policy shall not exceed the Non-Nuclear Limit of Liability, as specified in Item 6.A. of the Declarations, unless there has been a claim paid under Section l.A.2 of a Primary Property Policy or Section I. l(a) of a NEIL II Excess Property Policy applicable to the Unit insured under this Policy, or such claim for coverage under Section l.A.2 of a Primary Property Policy or Section 1.1 (a) of a NEIL II Excess Property Policy is denied solely based on an exclusion under those respective Policies that does not exist in this Policy, in which case the Insurer's liability shall not exceed the Limit of Liability specified in Item 6.A.

II.

EXCLUSIONS A.

General Exclusions

1.

D.

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 V.2.

E.

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 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.

NEIL I -April 1, 2017 El7-075-2 10 2017.01.23.21.13.04

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 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 NEIL I -April 1, 2017 El7-075-2 11 2017.01.23.21.13.04 1

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 ofinterest 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 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 ofNew 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 NEIL I -April 1, 2017 El 7-075-2 12 2017.01.23.21.13.04

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 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 ofreliefto 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.

(i)

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 ofits reasonable attorney's fees and costs (without consideration of the fees and costs incurred by the Insured).

G)

In the event the award is challenged in court and the challenge is denied, the party that challenged the award shall pay the reasonable attorneys' 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 NEIL I -April 1, 2017 E17-075-2 13 2017.01.23.21.13.04

Insureds ofNEIL 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 State ofNew 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.

Evaluations and Compliance with Loss Control Standards

1.

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, neitherthe 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.

3.

If a request made under Paragraph IV.G.2 is not complied with the Insurer may immediately suspend coverage as to the Affected Property and as to any Property Damage and/or Accidental Outage that could have been avoided or reduced had the Dangerous Condition been remedied, provided, however, that there will be coverage for Accidental Outage 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 IV.G.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.

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 Unit insured under this Policy, regardless of whether that Primary Policy is issued to the Insured or another party, the Insurer suspends coverage under that Primary Policy, such suspension of coverage shall apply with equal force and effect to this Policy. The Insurer shall notify the Insured of a suspension of coverage under this Policy in the same notice sent by the Insurer concerning suspension under the Primary Policy. Upon reinstatement of coverage under the Primary Policy, coverage shall be reinstated under this Policy in accordance with the provisions of Paragraph 9 of this Section.

In the event that the Insurer chooses to suspend coverage under this provision, it shall notify the Member Insured in writing of that decision.

9.

The coverage suspended in accordance with Paragraphs IV.G.3 and IV.G.5 above, as well as any coverage removed, 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 V.2.

The Insured shall be required to complete the Accidental Outage Claims Adjustment Form, as part of the Proof of Loss filing, in order to determine the Weekly Indemnity amount. The Insurer may deny coverage for such Outage ifthe Insured fails to comply with its obligation to provide immediate written notice thereof, but only if the Insurer demonstrates being prejudiced in its ability to adjust, assess or otherwise investigate the claims as a result of such failure.

2.

In the event of an Outage, the Insureds and each of their agents, employees or assigns, shall do all things reasonably necessary or desirable, or to the extent reasonably requested or required by the Insurer with respect to its investigation of such Outage, to the defense, safeguard, recovery and preservation of the damaged Insured Property.

It is a condition of this Policy that the Insureds shall repay the Insurer any recoveries made by the Insureds on account of any such Outage 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 loss 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.

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).

NEIL I -April 1, 2017 E17-075-2 19 2017.01.23.21.13.04

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 Members Insured to take the action. The terms regarding the Deposit Premium are set forth in Paragraph 3 below.

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 NEIL I -April 1, 2017 El7-075-2 20 2017.01.23.21.13.04

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 ofDirectors 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 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.

NEIL I-April 1, 2017 E17-075-2 21 2017.01.23.21.13.04

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, ifrequired, 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 may be adjusted at the anniversary of this Policy.

(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 V.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 V.2.

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 V.2, under this Policy shall be several and not joint and in proportion to their respective interests specified in the Declarations.

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.

NUCLEAR ELECTRIC INSURANCE LIMITED POLICYHOLDER DISCLOSURE NUCLEAR POLICY RENEWALS NOTICE OF TERRORISM INSURANCE COVERAGE EFFECTIVE JANUARY 8, 2015 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 caused by an act of terrorism could be limited by the terms of the endorsement. However, in accordance with the Terrorism Risk Insurance Program Reauthorization Act of2015, which took effect January 8, 2015, (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 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 caused 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 caused by 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, for the 2015 calendar year, the United States Government generally reimburses 85% of covered terrorism losses exceeding the statutorily established deductible paid by the insurance company providing the coverage. This amount will be decreased on a phased in basis, at a rate of 1 % per year, from 2016 to 2020, with the end result being that the United States Government will reduce reimbursement to 80% of covered terrorism losses for the year 2020. TRIPRA contains a $100 billion cap that limits U.S. Government reimbursement as well as insurers' liability for losses caused by 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 ofTRIPRA.
