                    the Trustee of a notice that, pursuant to Section 604 of
                    the St. Clair EDC Trust Indenture, the St. Clair EDC Trust
                    Indenture Trustee has terminated proceedings to enforce any
                    right under the St. Clair EDC Trust Indenture, then any
                    Redemption Demand shall thereby be rescinded by the St.
                    Clair EDC Trust Indenture Trustee, and no Demand Redemption
                    Notice shall be given, or, if already given, shall be
                    automatically annulled; but no such rescission or annulment
                    shall extend to or affect any subsequent default or impair
                    any right consequent thereon.
 
                      Anything herein contained to the contrary 
                    notwithstanding, the Trustee is not authorized to take
                    any action pursuant to a Redemption Demand and such
                    Redemption Demand shall be of no force or effect, unless it
                    is executed in the name of the St. Clair EDC Trust
                    Indenture Trustee by its President or one of its Vice
                    Presidents.

                         This bond and all other bonds of said series are issued and
                         to be issued under, and are all equally and ratably secured
                         (except insofar as any sinking, amortization, improvement or
                         analogous fund, established in accordance with the
                         provisions of the Indenture hereinafter mentioned, may
                         afford additional security for the bonds of any particular
                         series and except as provided in Section 3 of Article VI of
                         said Indenture) by an Indenture, dated as of October 1,
                         1924, duly executed by the Company to Bankers Trust Company,
                         a corporation of the State of New York, as Trustee, to which
                         Indenture and all indentures supplemental thereto (including
                         the Supplemental Indenture dated as of July 15, 1992)
                         reference is hereby made for a description of the properties
                         and franchises mortgaged and conveyed, the nature and extent
                         of the security, the terms and conditions upon which the
                         bonds are issued and under which additional bonds may be
                         issued, and the rights of the holders of the bonds and of
                         the Trustee in respect of such security (which Indenture and
                         all indentures supplemental thereto, including the
                         Supplemental Indenture dated as of July 15, 1992, are
                         hereinafter collectively called the "Indenture"). As
                         provided in the Indenture, said bonds may be for various
                         principal sums and are issuable in series, which may mature
                         at different times, may bear interest at different rates and
                         may otherwise vary as in said Indenture provided. With the
                         consent of the Company and to the extent permitted by and as
                         provided in the Indenture, the rights and obligations of the
                         Company and of the holders of the bonds and the terms and
                         provisions of the Indenture, or of any indenture
                         supplemental thereto, may be modified or altered in certain
                         respects by affirmative vote of at least eighty-five percent
                         (85%) in amount of the bonds then outstanding, and, if the
                         rights of one or more, but less than all, series of bonds
                         then outstanding are to be affected by the action proposed
                         to be taken, then also by affirmative vote of at least
                         eighty-five percent (85%) in amount of the series of bonds
                         so to be affected (excluding in every instance bonds
                         disqualified from voting by reason of the Company's interest
                         therein as specified in the Indenture); provided, however,
                         that, without the consent of the holder hereof, no such
                         modification or alteration shall, among other things, affect
                         the terms of payment of the principal of or the interest on
                         this bond, which in those respects is unconditional.
 
                           The holders of the bonds of 1992 Series CP, by their
                         acceptance of and holding thereof, consent and agree that
                         bonds of any series may be issued which mature on a date or
                         dates later than October 1, 2024 and also consent to the
                         deletion from the first paragraph of Section 5 of Article II
                         of the Indenture of the phrase "but in no event later than
                         October 1, 2024,". Such holders further agree that (a) such
                         consent shall, for all purposes of Article XV of the
                         Indenture and without further action on the part of such
                         holders, be deemed the affirmative vote of such holders at
                         any meeting called pursuant to said Article XV for the
                         purpose of approving such deletion, and (b) such deletion
                         shall become effective at such time as not less than
                         eighty-five per cent (85%) in principal amount of bonds
                         outstanding under the Indenture shall have consented thereto
                         substantially in the manner set forth in Section 4 of Part I
                         of the Supplemental Indenture dated as of July 15, 1992, or
                         in writing, or by affirmative vote cast at a meeting called
                         pursuant to said Article XV, or by any combination thereof.
 
                           This bond is redeemable upon the terms and conditions set
                         forth in the Indenture, including provision for redemption
                         upon demand of the St. Clair EDC Trust Indenture Trustee
                         following the occurrence of an Event of Default under the
                         St. Clair EDC Trust Indenture and the acceleration of the
                         principal of the St. Clair EDC Revenue Bonds.

                         with the Trustee (which shall have become available
                         for payment), in advance of the redemption date of any
                         of the bonds of 1992 Series CP (or portions thereof),
                         in trust for the redemption of such bonds (or portions
                         thereof) and the interest due or to become due
                         thereon, and thereupon all obligations of the Company
                         in respect of such bonds (or portions thereof) so to
                         be redeemed and such interest shall cease and be
                         discharged, and the holders thereof shall thereafter
                         be restricted exclusively to such funds for any and
                         all claims of whatsoever nature on their part under
                         the Indenture or with respect to such bonds (or
                         portions thereof) and interest.

                         Indenture, shall occur, the principal of all the bonds
                         issued thereunder may become or be declared due and
                         payable, in the manner, with the effect and subject to
                         the conditions provided in the Indenture.
 
                           Upon payment of the principal of, or premium,
