                                   WITNESSETH:

         WHEREAS, the Company entered into the Agreement with the Trustee on

         WHEREAS, the NRC has issued amendments (the "NRC Amendments") to its

         WHEREAS, Section 2.11 of the Agreement allows the Trustee and the
Company to amend the Agreement consistent with the purposes of the Agreement;
and

         WHEREAS, it is appropriate at this time to amend the Agreement to

         NOW THEREFORE, the Company and the Trustee hereby amend the Agreement,
as amended, to include said amendments to NRC regulations:

1.       The following Paragraph (5) shall be added to Section 2.01:

         Notwithstanding anything to the contrary in this Agreement, except for
         (i) payments of ordinary administrative costs (including taxes) and




         other incidental expenses of the Funds (including legal, accounting,
         actuarial, and trustee expenses) in connection with the operation of
         the Funds, (ii) withdrawals being made under 10 CFR 50.82(a)(8), and
         (iii) transfers between Qualified and Nonqualified Funds in accordance
         with the provisions of this Agreement, no disbursement or payment may
         be made from the Funds until written notice of the intention to make a
         disbursement or payment has been given to the Director, Office of
         Nuclear Reactor Regulation, or the Director, Office of Nuclear Material
         Safety and Safeguards, as applicable, at least 30 working days before
         the date of the intended disbursement or payment. The disbursement or
         payment from the Funds, if it is otherwise in compliance with the terms
         and conditions of this Agreement, may be made following the 30-working
         day notice period if no written notice of objection from the Director,
         Office of Nuclear Reactor Regulation, or the Director, Office of
         Nuclear Material Safety and Safeguards, as applicable, is received by
         the Trustee or the Company within the notice period. The required
         notice may be made by the Trustee or on the Trustee's behalf. This
         Paragraph 2.01(5) is intended to qualify each and every provision of
         this Agreement allowing distributions from the Funds, and in the event
         of any conflict between any such provision and this Paragraph, this
         Paragraph shall control.

2.       Except as set forth herein, the Agreement is hereby ratified and
         confirmed and remains in full force and effect.

3.       Each of the parties represents and warrants to the other parties that
         it has full authority to enter into this Amendment upon the terms and
         conditions hereof and that the individual executing this Amendment on
         its behalf has the requisite authority to bind the respective parties
         to this Amendment.

IN WITNESS WHEREOF, the parties hereto, each intending to be legally bound
hereby, have hereunto set their hands and seals as of the day and year first
above written.
