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

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

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

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

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

NUCLEAR ELECTRIC INSURANCE LIMITED WILMINGTON, DELAWARE Payments for Acts of Terrorism Endorsement Member Insured: STP Nuclear Operating Company Site: South Texas Project Endorsement No. 6 Policy Number: P10-075 Effective Date: October 1,2010 Effective Time of this Endorsement is 12:01 a.m. Standard Time in Hamilton, Bermuda.

I. The following Section is hereby added to the Policy:

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

(a) $3.24 billion (U.S. dollars) plus; (b) such additional amounts as the Insurer recovers for such Losses from reinsurance, indemnity, and any other source, applicable to such Losses.

2. Allocation of Resources (a) The amount determined under paragraph I above shall first be used to pay for all such Losses payable under all applicable Primary Property and Decontamination Liability Insurance Policies (excluding any Losses payable under all Business Interruption and/or Extra Expense Insurance Policy Endorsements), Primary Property and Decontamination Insurance Policies (excluding any Losses payable under all Business Interruption and/or Extra Expense Insurance Policy Endorsements), Operating Facility Policies, Decontamination Liability, Decommissioning Liability and Excess Property Insurance Policies, Decontamination, Decommissioning Primary - October 1, 2010 1 2009.01.26.16.53.48 P10-075

NUCLEAR ELECTRIC INSURANCE LIMITED WILMINGTON, DELAWARE and Excess Property Insurance Policies, Blanket Excess Decontamination Liability, Decommissioning Liability and Excess Property Insurance Policies, and Blanket Excess Decontamination, Decommissioning and Excess Property Insurance Policies (collectively "Property Losses").

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

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

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

4. Relevant Period The twelve-month period specified above shall commence on the date of the first Accidental Property Damage caused by an Act of Terrorism. The first Accidental Property Damage caused by an Act of Terrorism that occurs after this or any other twelve-month period shall trigger a new twelve-month period.

5. Definitions For the purposes of this Section only:

(a) "Act of Terrorism" means any act by a person, group, or organization that appears to be intended to: (i) intimidate or coerce a civilian population, or (ii) disrupt any segment of the economy in the country where the insured plant is located; or (iii) influence the policy of a government by intimidation or coercion; or (iv) affect the conduct of a government by mass destruction; provided, however, that an Act of Terrorism for purposes of this Policy shall not include any act excluded by the War Risk Exclusion.

Primary - October 1,2010 2 2009.01.26.16.53.48 P 10-075

NUCLEAR ELECTRIC INSURANCE LIMITED WILMINGTON, DELAWARE (b) "Nuclear Insurance Policy" means any Primary Property and Decontamination Liability Insurance Policy, or Primary Property and Decontamination Insurance Policy, or Operating Facility Policy, or any Decontamination Liability, Decommissioning Liability and Excess Property Insurance Policy, or Decontamination, Decommissioning and Excess Property Insurance Policy or any Blanket Excess Decontamination Liability, Decommissioning Liability And Excess Property Insurance Policy, or Blandet Excess Decontamination, Decommissioning And Excess Property Insurance Policy, other than this Policy, issued by the Insurer or by Overseas NEIL Limited.

6. Authorized Changes to this Section The Insurer's Board of Directors will have the authority to alter or replace the definition of the term "Act of Terrorism" and any other provision of this Section in order to facilitate the availability of resources that may be made available by the Government in the country where the insured plant is located.

(a) The Insurer and the Insured mutually acknowledge that the tbrm, 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 ternms, are disputed. For the foregoing reasons, the Insurer and the Insured agree that the following principles shall govern the interpretation of the Policy:

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

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 tluee (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.

(b) The Insurer, in the sole discretion of the Board of Directors, may require the Member Insured to provide assurance to the Insurer of tile 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.

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

(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 ofall Retrospective Premium Adjustments under this Policy shall not exceed the Retrospective Premium Adjustment set forth in Item 5.13 of the Declarations.

(3) Subject to the provisions with respect to calls made in the event of failure to pay by Delinquent Members, the amount of any call for a Retrospective Premium Adjustment hereunder shall bear the same relation to the total Retrospective Premium Adjustment, payable by all Member Insureds of the Insurer under such call as the highest Premium plus Additional NEIL tt - October 1, 201t) 24 2010.06.1 1.14.36.36 X10-075

Premium determined under subparagraph (a)(ii) above bears to the aggregate Premiums plus Additional Premiums, used to calculate the total of all such calls, under this Policy and all Other Insurance Policies with coverage effective during the Policy Year.

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

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

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

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

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

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

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

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

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

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

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

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

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