<PAGE>   15
                         REVERSE OF SECURITIZATION BOND



         This Class A-[ ] Securitization Bond is one of a duly authorized issue
of Securitization Bonds of the Issuer, designated as its Securitization Bonds,
Series 2001-1 (herein called the "Securitization Bonds"), issued and to be
issued in one or more Series, which Series are issuable in one or more Classes.
The Series 2001-1 Securitization Bonds consist of seven Classes, including the
Series 2001-1 Securitization Bonds, Class A-[ ] (herein called the "Class A-[ ]
Securitization Bonds"). The Class A-[ ] Securitization Bonds have been issued
under an indenture dated as of [     ], 2001, and a series supplement thereto
dated as of [     ], 2001 (such series supplement, as supplemented or amended,
the "Series Supplement" and, collectively with such indenture, as supplemented
or amended, the "Indenture"), each between the Issuer and the Bank of New York,
as Trustee (the "Trustee", which term includes any successor trustee under the
Indenture), to which Indenture and all indentures supplemental thereto reference
is hereby made for a statement of the Collateral pledged, the nature and extent
of the security, the respective rights, obligations and immunities thereunder of
the Issuer, the Trustee and the Holders of the Securitization Bonds and the
terms and conditions under which additional Securitization Bonds may be issued.
All terms used in this Class A-[ ] Securitization Bond that are defined in the
Indenture, as supplemented or amended, shall have the meanings assigned to them
in the Indenture.

         [The Class A-[ ] Securitization Bonds, the other Classes of Series
2001-1 Securitization Bonds and any other Series of Securitization Bonds issued
by the Issuer are and will be equally and ratably secured by the Collateral
pledged as security therefor as provided in the Indenture.]

         The principal of this Class A-[ ] Securitization Bond shall be payable
on each Payment Date only to the extent that amounts in the Collection Account
are available therefor, and only until the outstanding principal balance of the
Class A-[ ] Securitization Bonds on such Payment Date (after giving effect to
all payments of principal, if any, made on such Payment Date) has been reduced
to the principal balance specified in the Expected Amortization Schedule which
is attached to the Series Supplement as Schedule A, unless payable earlier
either because

                  (i)      an Event of Default has occurred and is continuing
         and the Trustee or the Holders of Securitization Bonds representing a
         majority of the Outstanding Amount of the Securitization Bonds of all
         Series have declared the Securitization Bonds to be immediately due and
         payable in accordance with Section 5.02 of the Indenture, or

                  (ii)     the Issuer, at its option, has called for the
         redemption of the Series 2001-1 Securitization Bonds in whole pursuant
         to Section 8(b) of the Series Supplement and Section 10.01 of the
         Indenture.

         However, actual principal payments may be made in lesser than expected
amounts and at later than expected times as determined pursuant to Section 8.02
of the Indenture. The entire unpaid principal amount of this Class A-[ ]
Securitization Bond shall be due and payable on the earlier of the Final
Maturity Date hereof and the Redemption Date, if any. Notwithstanding the
foregoing, the entire unpaid principal amount of the Securitization Bonds shall
be due and payable, if not then previously paid, on the date on which an Event
of Default shall have


                                   Exhibit A-6
<PAGE>   16
occurred and be continuing and the Trustee or the Holders of the Securitization
Bonds of all Series representing not less than a majority of the Outstanding
Amount of the Securitization Bonds have declared the Securitization Bonds to be
immediately due and payable in the manner provided in Section 5.02 of the
Indenture. All principal payments on the Class A-[ ] Securitization Bonds shall
be made pro rata to the Class A-[ ] Securitization Bondholders entitled thereto
based on the respective principal amounts of the Class A-[ ] Securitization
Bonds held by them.

         Payments of interest on this Class A-[ ] Securitization Bond due and
payable on each Payment Date, together with the instalment of principal payable
on this Class A-[ ] Securitization Bond on such Payment Date shall be made by
check mailed first-class, postage prepaid, to the Person whose name appears as
the Registered Holder of this Class A-[ ] Securitization Bond (or one or more
predecessors of such Securitization Bond) in the Securitization Bond Register as
of the close of business on the Record Date or in such other manner as may be
provided in the Series Supplement, except that with respect to Class A-[ ]
Securitization Bonds registered on the Record Date in the name of a Clearing
Agency or its nominee, payments will be made by wire transfer in immediately
available funds to the account designated by such Clearing Agency and except for
the final instalment of principal payable with respect to this Class A-[ ]
Securitization Bond on a Payment Date which shall be payable as provided below.
Such checks shall be mailed to the Person entitled thereto at the address of
such Person as it appears in the Securitization Bond Register as of the
applicable Record Date without requiring that this Class A-[ ] Securitization
Bond be submitted for notation of payment. Any reduction in the principal amount
of this Class A-[ ] Securitization Bond (or any one or more predecessors to such
Securitization Bond) effected by any payments made on any Payment Date shall be
binding upon all future Holders of this Class A-[ ] Securitization Bond and of
any Class A-[ ] Securitization Bond issued upon the registration of transfer
hereof or in exchange hereof or in lieu hereof, whether or not noted hereon. If
funds are expected to be available, as provided in the Indenture, for payment in
full of the then remaining unpaid principal amount of this Class A-[ ]
Securitization Bond on a Payment Date, then the Trustee, in the name of and on
behalf of the Issuer, will notify the Person who was the Registered Holder
hereof as of the Record Date immediately preceding such Payment Date by notice
mailed no later than ten days prior to such final Payment Date and shall specify
that such final instalment will be payable to the Registered Holder hereof as of
the Record Date immediately preceding such final Payment Date and only upon
presentation and surrender of this Class A-[ ] Securitization Bond and shall
specify the place where this Class A-[ ] Securitization Bond may be presented
and surrendered for payment of such instalment.

         The Issuer shall pay interest on overdue instalments of interest on
this Class A-[ ] Securitization Bond at the Interest Rate for Class A-[ ] to the
extent lawful.

         As provided in the Indenture, the Class A-[ ] Securitization Bonds may
be redeemed, in whole, but not in part, in certain circumstances as provided in
Section 8(b) of the Series Supplement and Section 10.01 of the Indenture.

         This Class A-[ ] Securitization Bond is a Securitization Bond as such
term is defined in the Statute. Principal and interest due and payable on this
Securitization Bond are payable from and secured primarily by securitization
property authorized by a financing order issued by the


                                   Exhibit A-7
<PAGE>   17
Michigan Public Service Commission pursuant to the Statute. Securitization
property includes the irrevocable right to impose and collect certain
non-bypassable charges (defined in the Statute as "Securitization charges") to
be included in electric utility bills of all electric service retail customers
of The Detroit Edison Company, a Michigan electric utility.

         The Statute provides that:

                  The state pledges, for the benefit and protection of the
                  financing parties and the electric utility, that it will not
                  take or permit any action that would impair the value of
                  securitization property, reduce or alter, except as allowed
                  under [the Statute in connection with periodic adjustments to
                  the SB Charge], or impair the securitization charges to be
                  imposed, collected, and remitted to financing parties, until
                  the principal, interest and premium, and any other charges
                  incurred and contracts to be performed in connection with the
                  related securitization bonds have been paid and performed in
                  full. Any party issuing securitization bonds is authorized to
                  include this pledge in any documentation relating to those
                  bonds.

         As provided in the Indenture and subject to certain limitations set
forth therein, the transfer of this Class A-[ ] Securitization Bond may be
registered in the Securitization Bond Register upon surrender of this Class
A-[ ] Securitization Bond for registration of transfer at the office or agency
designated by the Issuer pursuant to the Indenture, duly endorsed by, or
accompanied by a written instrument of transfer in form satisfactory to the
Trustee duly executed by the Holder hereof or his attorney duly authorized in
writing, with such signature guaranteed by an Eligible Guarantor Institution,
and thereupon one or more new Class A-[ ] Securitization Bonds of any Authorized
Denominations and in the same aggregate initial principal amount will be issued
to the designated transferee or transferees. No service charge will be charged
for any registration of transfer or exchange of this Class A-[ ] Securitization
Bond, but the transferor may be required to pay a sum sufficient to cover any
tax or other governmental charge that may be imposed in connection with any
registration of transfer or exchange.

         Prior to the due presentment for registration of transfer of this Class
A-[ ] Securitization Bond, the Issuer, the Trustee and any agent of the Issuer
or the Trustee may treat the Person in whose name this Class A-[ ]
Securitization Bond is registered (as of the day of determination) as the owner
hereof for the purpose of receiving payments of principal of and interest on
this Class A-[ ] Securitization Bond and for all other purposes whatsoever,
whether or not this Class A-[ ] Securitization Bond may be overdue, and neither
the Issuer, the Trustee nor any such agent shall be affected by notice to the
contrary.

         The Indenture permits, with certain exceptions as therein provided, the
amendment thereof and the modification of the rights and obligations of the
Issuer and the rights of the Holders of the Securitization Bonds under the
Indenture at any time by the Issuer with the consent of the Holders of
Securitization Bonds representing a majority of the Outstanding Amount of all
Securitization Bonds at the time Outstanding of each Series or Class to be
affected and upon satisfaction of the Rating Agency Condition. The Indenture
also contains provisions permitting the Holders of Securitization Bonds
representing specified percentages of the Outstanding Amount of the
Securitization Bonds of all Series, on behalf of the Holders of all the


                                   Exhibit A-8
<PAGE>   18
Securitization Bonds, to waive compliance by the Issuer with certain provisions
of the Indenture and certain past defaults under the Indenture and their
consequences. Any such consent or waiver by the Holder of this Class A-[ ]
Securitization Bond (or any one of more predecessors of such securitization
bonds) shall be conclusive and binding upon such Holder and upon all future
Holders of this Class A-[ ] Securitization Bond and of any Class A-[ ]
Securitization Bond issued upon the registration of transfer hereof or in
exchange hereof or in lieu hereof whether or not notation of such consent or
waiver is made upon this Class A-[ ] Securitization Bond. The Indenture also
permits the Trustee to amend or waive certain terms and conditions set forth in
the Indenture without the consent of Holders of the Securitization Bonds issued
thereunder.

         The term "Issuer" as used in this Class A-[ ] Securitization Bond
includes any successor to the Issuer under the Indenture.

         The Issuer is permitted by the Indenture, under certain circumstances,
to merge or consolidate, subject to the rights of the Trustee and the Holders of
Securitization Bonds under the Indenture.

         The Class A-[ ] Securitization Bonds are issuable only in registered
form in Authorized Denominations as provided in the Indenture and the Series
Supplement, subject to certain limitations therein set forth.

         This Class A-[ ] Securitization Bond and the Indenture shall be
construed in accordance with the laws of the State of Michigan, without
reference to its conflict of laws provisions, and the obligations, rights and
remedies of the parties hereunder and thereunder shall be determined in
accordance with such laws.

         No reference herein to the Indenture and no provision of this Class A-[
] Securitization Bond or of the Indenture shall alter or impair the obligation
of the Issuer, which is absolute and unconditional, to pay the principal of and
interest on this Class A-[ ] Securitization Bond at the times and rate and in
the currency herein prescribed.
