                                   ARTICLE TWO

                        TITLE AND TERMS OF THE SECURITIES

     SECTION 2.01. Title of the Securities; Stated Maturity. This Twentieth
Supplemental Indenture hereby establishes a series of Securities, which shall be
known as the Company's "2006 Series A 6.625% Senior Notes due 2036" (the
"Notes"). For purposes of the Original Indenture, the Notes shall constitute a
single series of Securities. The Stated Maturity on which the principal of the
Notes shall be due and payable will be June 1, 2036.

     SECTION 2.02. Certain Variations from the Original Indenture.

     (a) The Notes shall have the benefit of the provisions of Article Four of
the Original Indenture and shall have the benefit of, or be subject to, the
other related provisions of the Original Indenture relating to the grant of
security, including (for avoidance of doubt and not for purposes of limitation)
the Granting Clause, the definitions of "Deliverable Mortgage Bonds,"
"Deliverable Securities," "Designated Mortgage Bonds," "Grant," "Mortgage,"
"Mortgage Bonds," "Mortgage Trustee," "Previously Delivered Mortgage Bonds," and
"Trust Estate," Section 301(20), Sections 301(a)(v), (ix), (x) and (xi),
Sections 301(b)(ii) and (iii), Section 301(d), and Sections 601(4) and (8),
subject, in each case, to the release provisions provided for in Section 4.02
herein. In addition, on and after the Release Date, unless Substitute Mortgage
Bonds are issued to secure the Notes, the Notes shall have the benefit of the
additional covenants set forth in Article Three hereof.

     (b) Section 503 of the Original Indenture shall apply to the Notes. The
following shall be an additional condition to defeasance of the Notes under
Section 503: the Company shall have delivered to the Trustee an Opinion of
Counsel stating that (i) the Company has received from the Internal Revenue
Service a letter ruling, or there has been published by the Internal Revenue
Service a Revenue Ruling, or (ii) since the date of execution of this Twentieth
Supplemental Indenture, there has been a change in the applicable U.S. Federal
income tax law, in either case to the effect that, the Holders of such
Outstanding Notes appertaining thereto will not recognize income, gain or loss
for U.S. Federal income tax purposes as a result of such defeasance and will be
subject to U.S. Federal income tax on the same amounts, in the same manner and
at the same times as would have been the case if such defeasance had not
occurred, and, also, to the effect that, after the 123rd day after the date of
deposit, all money and other property as provided pursuant to Section 503 of the
Original Indenture (including the proceeds thereof) deposited or caused to be
deposited with the Trustee (or other qualifying trustee) pursuant to Section 503
of the Original Indenture to be held in trust will not be subject to any case or
proceeding (whether voluntary or involuntary) in respect of the Company under
any Federal or State bankruptcy, insolvency, reorganization or other similar
law, or any decree or order for relief in respect of the Company issued in
connection therewith.

     SECTION 2.03. Amount and Denominations; DTC

     (a) The aggregate principal amount of Notes that may be issued under this
Twentieth Supplemental Indenture is limited to $250,000,000 (except as provided
in Section 301(2) of the Original Indenture); provided that the Company may,
without the consent of the Holders of the


                                       4

<PAGE>

Outstanding Notes, "reopen" the series of the Notes so as to increase the
aggregate principal amount of the Notes Outstanding in compliance with the
procedures set forth in the Original Indenture, including Section 301 and
Section 303 thereof, so long as any such additional Notes have the same terms,
conditions and CUSIP number (including, without limitation, rights to security
and to receive accrued and unpaid interest) as the Notes then Outstanding. No
additional Notes may be issued if an Event of Default has occurred with respect
to the Notes. The Notes shall be issuable only in fully registered form and, as
permitted by Section 301 and Section 302 of the Original Indenture, in
denominations of $1,000 and integral multiples thereof. The Notes will initially
be issued in global form (the "Global Securities") under a book-entry system,
registered in the name of The Depository Trust Company, as depository ("DTC"),
or its nominee, which is hereby designated as "Depository" under the Indenture.

     (b) If (i) the Depository notifies the Company that it is unwilling or
unable to continue as Depository for such Global Security or if at any time such
Depository ceases to be a clearing agency registered under the Securities
Exchange Act of 1934, and, in either such case, the Company does not appoint a
successor Depository within 90 days thereafter, or (ii) there shall have
occurred and be continuing an Event of Default or an event which, with the
giving of notice or lapse of time, or both, would constitute an Event of
Default, certificates for the Notes will be registered and delivered to the
Holders of record. Upon receipt of a withdrawal request from the Company, the
Depository will notify its participants of the receipt of a withdrawal request
from the Company, notifying participants that they may utilize the Depository's
withdrawal procedures if they wish to withdraw their securities from the
Depository. To the extent that the book-entry system is discontinued, or if the
Company fails to appoint a successor Depository, certificates for the Notes will
be registered and delivered to the Holders of record.

     SECTION 2.04. Certain Terms of the Notes.

     (a) The Notes shall bear interest at the rate of 6.625% per annum on the
principal amount thereof from the date of original issuance, or from the most
recent Interest Payment Date to which interest has been paid or duly provided
for, until the principal of the Notes becomes due and payable, and on any
overdue principal and premium and (to the extent that payment of such interest
is enforceable under applicable law) on any overdue installment of interest at
the same rate per annum during such overdue period. Interest on the Notes will
be payable semi-annually in arrears on June 1 and December 1 of each year (each
such date, an "Interest Payment Date"), commencing December 1, 2006. The amount
of interest payable for any period shall be computed on the basis of a 360-day
year and twelve 30-day months.

     (b) In the event that any Interest Payment Date, redemption date or other
date of Maturity of the Notes is not a Business Day, then payment of the amount
payable on such date will be made on the next succeeding day which is a Business
Day (and without any interest or other payment in respect of any such delay), in
each case with the same force and effect as if made on such date. The interest
installment so payable, and punctually paid or duly provided for, on any
Interest Payment Date with respect to any Note will, as provided in the Original
Indenture, be paid to the person in whose name the Note (or one or more
Predecessor Securities, as defined in the Original Indenture) is registered at
the close of business on the relevant record date for such interest installment,
which shall be the fifteenth calendar day (whether or not a Business Day) prior
to the relevant Interest Payment Date (the "Regular Record Date"). Any such
interest installment not


                                       5

<PAGE>

punctually paid or duly provided for shall forthwith cease to be payable to the
registered Holders on such Regular Record Date, and may either be paid to the
person in whose name the Note (or one or more Predecessor Securities) is
registered at the close of business on a Special Record Date to be fixed by the
Trustee for the payment of such defaulted interest, notice whereof shall be
given to the registered Holders of the Notes not less than ten days prior to
such Special Record Date, or may be paid at any time in any other lawful manner
not inconsistent with the requirements of any securities exchange on which the
Notes may be listed, and upon such notice as may be required by such exchange,
all as more fully provided in the Original Indenture. The principal of, and
premium, if any, and the interest on the Notes shall be payable at the office or
agency of the Company maintained for that purpose in the Borough of Manhattan,
the City of New York, in any coin or currency of the United States of America
that at the time of payment is legal tender for payment of public and private
debts; provided, however, that payment of interest may be made at the option of
the Company by check mailed to the registered Holder at the close of business on
the Regular Record Date at such address as shall appear in the Security
Register. Notwithstanding the foregoing, so long as the Notes are Global
Securities and are held in book-entry form through the facilities of the
Depository, payments on the Notes will be made to the Depository or its nominee
in accordance with arrangements then in effect between the Trustee and the
Depository.

     (c) The Notes are not subject to repayment at the option of the Holders
thereof and are not subject to any sinking fund. As provided in the form of
Notes attached hereto as Exhibit A, the Notes are subject to optional
redemption, as a whole or in part, by the Company prior to Stated Maturity of
the principal thereof on the terms set forth therein. Except as modified in the
form of Notes, redemptions shall be effected in accordance with Article Twelve
of the Original Indenture.

     (d) The Notes shall have such other terms and provisions as are set forth
in the form of Notes attached hereto as Exhibit A (which is incorporated by
reference in and made a part of this Twentieth Supplemental Indenture as if set
forth in full at this place).

     SECTION 2.06. Form of Notes. Attached hereto as Exhibit A is the form of
the Notes. If the Company elects to have the Notes secured by Substitute
Mortgage Bonds on and after the Release Date, the terms of the Notes shall be
amended to make appropriate reference to the Substitute Mortgage and the
Substitute Mortgage Bonds; provided, that the consent of Holders shall not be
required in connection with such amendment.

                                  ARTICLE THREE

                              ADDITIONAL COVENANTS

     SECTION 3.01. Limitations on Liens.

     (a) From and after the Release Date, unless Substitute Mortgage Bonds are
issued to secure the Notes, so long as any Notes are outstanding, the Company
may not issue, assume, guarantee (including any contingent obligation to
purchase) or permit to exist any Debt that is secured by any mortgage, security
interest, pledge or lien ("Lien") of or upon any Operating Property owned by the
Company, whether owned at the Release Date or subsequently acquired, without
effectively securing the Notes (together with, if the Company shall so
determine, any other


                                       6

<PAGE>

indebtedness of the Company ranking equally with the Notes) equally and ratably
with the Debt (but only so long as the Debt is so secured).

     The foregoing restriction will not apply to:

          (i) Liens on any Operating Property existing at the time of its
     acquisition and not created in contemplation of the acquisition;

          (ii) Liens on Operating Property of a corporation existing at the time
     the corporation is merged into or consolidated with the Company, or at the
     time the corporation disposes of substantially all of its properties (or
     those of a division) to the Company, provided that the Lien is not extended
     to property owned by the Company immediately prior to the merger,
     consolidation or other disposition and is not created in contemplation of
     the merger, consolidation or other disposition;

          (iii) Liens on Operating Property to secure the cost of acquisition,
     construction, development or substantial repair, alteration or improvement
     of such property or to secure indebtedness incurred to provide funds for
     any of these purposes or for reimbursement of funds previously expended for
     any of these purposes, provided the Liens are created or assumed
     contemporaneously with, or within 18 months after, the acquisition or the
     completion of substantial repair or alteration, construction, development
     or substantial improvement or within 6 months thereafter pursuant to a
     commitment for financing arranged with a lender or investor within such
     18-month period;

          (iv) Liens in favor of the United States or any state or any
     department, agency or instrumentality or political subdivision of the
     United States or any state, or for the benefit of holders of securities
     issued by any of these entities, to secure any Debt incurred for the
     purpose of financing all or any part of the purchase price or the cost of
     substantially repairing or altering, constructing, developing or
     substantially improving the Operating Property; or

          (v) Any extension, renewal or replacement (or successive extensions,
     renewals or replacements), in whole or in part, of any Lien referred to in
     the exceptions listed above, provided, however, that the principal amount
     of Debt secured thereby and not otherwise authorized by those exceptions
     listed above shall not exceed the principal amount of Debt, plus any
     premium or fee payable in connection with any such extension, renewal or
     replacement, so secured at the time of such extension, renewal or
     replacement.

     (b) Notwithstanding the foregoing restrictions, the Company may issue,
assume or guarantee Debt secured by a Lien which would otherwise be subject to
the foregoing restrictions up to an aggregate amount which, together with all
other of the Company's secured Debt (not including secured Debt permitted under
any of the foregoing exceptions) and the Value of Sale and Lease-Back
Transactions existing at such time (other than Sale and Lease-Back Transactions
the proceeds of which have been applied to the retirement of certain
indebtedness, Sale and Lease-Back Transactions in which the property involved
would have been permitted to be subjected to a Lien under any of the foregoing
exceptions, and Sale and Lease-Back Transactions that are permitted by the first
sentence of Section 3.02 below), does not exceed the greater of 10% of the
Company's Net Tangible Assets or 10% of the Company's Capitalization. The
foregoing


                                       7

<PAGE>

restrictions do not limit the Company's ability to place Liens on (i) the
capital stock of any of the Company's subsidiaries or (ii) the assets of any of
the Company's subsidiaries.

     SECTION 3.02. Limitations on Sale and Lease-Back Transactions. So long as
the Notes are outstanding from and after the Release Date, unless Substitute
Mortgage Bonds are issued to secure the Notes, the Company may not enter into or
permit to exist any Sale and Lease-Back Transaction with respect to any
Operating Property (except for leases for a term, including any renewal or
potential renewal, of not more than 48 months), if the purchaser's commitment is
obtained more than 18 months after the later of the completion of the
acquisition, construction or development of the Operating Property or the
placing in operation of the Operating Property or of the Operating Property as
constructed or developed or substantially repaired, altered or improved. This
restriction will not apply if (a) the Company would be entitled pursuant to
Section 3.01(a) above to issue, assume, guarantee or permit to exist Debt
secured by a Lien on the Operating Property without equally and ratably securing
the Notes, (b) after giving effect to the Sale and Lease-Back Transaction,
pursuant to Section 3.01(b) above, the Company could incur at least $1.00 of
additional Debt secured by Liens (other than Liens permitted by clause (a)), or
(c) the Company applies within 180 days an amount equal to, in the case of a
sale or transfer for cash, the net proceeds (not less than the fair value of the
Operating Property so leased), and, otherwise, an amount equal to the fair value
(as determined by the Board of Directors of the Company) of the Operating
Property so leased to the retirement of Notes or other Debt of the Company
ranking equally with the Notes; provided, however, that any such retirement of
Notes shall be in accordance with the terms and provisions of the Indenture and
the Notes; provided, further, that the amount to be applied to such retirement
of Notes or other Debt shall be reduced by an amount equal to the sum of (a) an
amount equal to the redemption price with respect to Notes delivered within such
one hundred eighty (180)-day period to the Trustee for retirement and
cancellation and (b) the principal amount, plus any premium or fee paid in
connection with any redemption in accordance with the terms of other Debt
voluntarily retired by the Company within such one hundred eighty (180)-day
period, excluding in each case retirements pursuant to mandatory sinking fund or
prepayment provisions and payments at Stated Maturity.

     SECTION 3.03. Waiver. Section 1109 of the Original Indenture shall apply to
the covenants set forth in Sections 3.01 and 3.02 above at any time such
covenants are in effect.

                                  ARTICLE FOUR

                         SECURITY AND RELEASE PROVISIONS

     SECTION 4.01. Security. Subject to Section 4.02 below, as provided in and
pursuant to Article Four of the Original Indenture, the Notes will be secured as
to payments of principal, interest and premium, if any, by a series of Mortgage
Bonds (the "General and Refunding Mortgage Bonds, 2006 Series A", the "Bonds,"
the "Bonds of the related series" or the "related series of Bonds") of the
Company to be issued concurrently with the issuance of the Notes under and
secured by a Mortgage and Deed of Trust, dated as of October 1, 1924, between
the Company and J.P. Morgan Trust Company, National Association, as successor
trustee (the "Mortgage Trustee"), as amended and supplemented by various
supplemental indentures, including the supplemental indenture, dated as of May
15, 2006, creating the Bonds (collectively, the "Mortgage"), pledged by the
Company for the benefit of the Holders of the Notes to the


                                       8

<PAGE>

Trustee under this Twentieth Supplemental Indenture. The Bonds shall be issued
in an aggregate principal amount equal to the aggregate principal amount of the
Notes.

     SECTION 4.02. Release. Until the Release Date and subject to Article Four
of the Original Indenture, the Bonds of the related series issued and delivered
to the Trustee shall serve as security for any and all obligations of the
Company under all Notes from time to time Outstanding, including, but not
limited to (1) the full and prompt payment of the principal and premium, if any,
on the Notes when and as the same shall become due and payable in accordance
with the terms and provisions of the Indenture or the Notes, either at the
Stated Maturity thereof, upon acceleration of the maturity thereof, upon
redemption, or otherwise, and (2) the full and prompt payment of any interest on
the Notes when and as the same shall become due and payable in accordance with
the terms and provisions of this Indenture or the Notes including, if and to the
extent provided for in the Notes, interest on overdue installments of principal
and (to the extent permitted by law) interest on overdue installments of
interest.

     Each supplemental indenture to the Mortgage pursuant to which any Bonds are
issued shall contain a provision to the effect that any payment by the Company
hereunder of principal of or premium or interest on Notes which shall have been
authenticated and delivered in connection with the issuance and delivery to the
Trustee of such Bonds (other than by the application of the proceeds of a
payment in respect of such Bonds) shall to the extent thereof, be deemed to
satisfy and discharge the obligation of the Company, if any, to make a payment
of principal, premium or interest, as the case may be, in respect of such Bonds
which is then due.

     Notwithstanding anything in the Original Indenture to the contrary, from
and after the Release Date, the obligation of the Company to make payment with
respect to the principal of and premium, if any, and interest on the Bonds shall
be deemed satisfied and discharged as provided in the supplemental indenture or
indentures to the Mortgage creating such Bonds and the Bonds shall cease to
secure in any manner Notes theretofore or subsequently issued; the Trustee shall
thereupon surrender the Bonds to the Mortgage Trustee for cancellation and
execute and deliver such proper instruments of release as may be required. From
and after the Release Date, all Notes, whether theretofore or subsequently
issued, shall, at the Company's option, either (i) become unsecured or (ii) be
secured by Substitute Mortgage Bonds pursuant to Section 4.03 below, and any
conditions to the issuance of Notes that refer or relate to Bonds or the
Mortgage shall be inapplicable (except as such conditions shall be deemed to
refer to Substitute Mortgage Bonds or a Substitute Mortgage pursuant to Section
4.03 below). From and after the Release Date, the Company shall not issue any
additional Mortgage Bonds, including Pledged Bonds, under the Mortgage. Notice
of the occurrence of the Release Date shall be given by the Trustee to the
Holders of the Notes in the manner provided for in the Original Indenture not
later than 30 days after the Company notifies the Trustee of the occurrence of
the Release Date.

     In connection with the establishment of the occurrence of the Release Date,
the Trustee shall be entitled to receive, may presume the correctness of, and
shall be fully protected in relying upon, an Officers' Certificate designating
the Release Date and stating that the conditions to the occurrence of the
Release Date have been satisfied.

     When the obligation of the Company to make payments with respect to the
principal of, and premium, if any, and interest on all or any part of the Bonds
shall be satisfied or deemed satisfied pursuant to the Original Indenture or
pursuant to this Twentieth Supplemental Indenture, the


                                       9

<PAGE>

Trustee shall, upon written request of the Company, deliver to the Company
without charge therefor all of the Bonds so satisfied or deemed satisfied,
together with such appropriate instruments of transfer or release as may be
reasonably requested by the Company. All Bonds delivered to the Company in
accordance with this Section shall be delivered by the Company to the Mortgage
Trustee for cancellation.

     SECTION 4.03. Substitute Mortgage Bonds.

     (a) The Company shall notify the Trustee not less than 90 days prior to the
Release Date (or such shorter period as the Company and the Trustee may agree)
if the Company has determined to deliver to the Trustee on the Release Date
Substitute Mortgage Bonds in an aggregate principal amount equal to the
aggregate principal amount of Notes and any other Securities subject to the
release provisions Outstanding on the Release Date, in trust for the benefit of
the Holders from time to time of the Notes and any other Securities subject to
the release provisions issued under the Original Indenture, as supplemented, as
security for any and all obligations of the Company under the Notes and any
other Securities subject to the release provisions, including but not limited
to, (1) the full and prompt payment of the principal of and premium, if any, on
the Notes and any other Securities subject to the release provisions when and as
the same shall become due and payable in accordance with the terms and
provisions of the Original Indenture, as supplemented, or the Notes or such
other Securities subject to the release provisions, either at the stated
maturity thereof, upon acceleration of the maturity thereof or upon redemption,
and (2) the full and prompt payment of any interest on the Notes and any other
Securities subject to the release provisions when and as the same shall become
due and payable in accordance with the terms and provisions of the Original
Indenture, as supplemented, or the Notes or such other Securities subject to the
release provisions.

     (b) The Substitute Mortgage Bonds to be delivered pursuant to the notice
described in Section 4.03(a) shall be delivered in separate series and issues
corresponding to the series and issues of Notes and other Securities subject to
the release provisions Outstanding on the Release Date, each series or issue of
Substitute Mortgage Bonds having the same stated rate or rates of interest (or
interest calculated in the same manner), Interest Payment Dates, stated maturity
date and redemption provisions, and in the same aggregate principal amount, as
the related series or issue of Notes or other Securities subject to the release
provisions outstanding on the Release Date. The Company shall enter into a
Substitute Mortgage for the issuance of Substitute Mortgage Bonds, and designate
it as such in the notice.

     (c) The notice described in Section 4.03(a) shall also state that on the
Release Date the Company shall deliver to the Trustee a supplemental indenture
to the Original Indenture that will provide, among other things, that upon the
issuance of Notes and other Securities subject to the release provisions on or
after the Release Date, the Company shall deliver to the Trustee in trust for
the benefit of the Holders as described in Section 4.03(a) hereof, and the
Trustee shall accept therefor, related series of Substitute Mortgage Bonds
registered in the name of the Trustee and conforming to the requirements therein
specified.

     (d) The determination whether to deliver Substitute Mortgage Bonds shall be
made in the Company's sole discretion and without any obligation to do so.


                                       10

<PAGE>

     (e) In the event that the Company does not deliver the notice described in
Section 4.03(a), the Notes and other Securities subject to the release
provisions Outstanding on the Release Date shall, as of the Release Date, no
longer be entitled to the benefit of the pledge of the Pledged Bonds and shall
thereafter be general unsecured obligations of the Company.

     (f) Article Four and related provisions of the Original Indenture shall
apply to Substitute Mortgage Bonds pledged to the Trustee hereunder and the
provisions thereof shall be deemed to refer to the Substitute Mortgage and the
Substitute Mortgage Bonds. If the Company elects to have the Notes secured by
Substitute Mortgage Bonds on and after the Release Date, Article Four and
related provisions may be amended to make appropriate reference to the
Substitute Mortgage and the Substitute Mortgage Bonds; provided, that the
consent of Holders shall not be required in connection with such amendment.

     SECTION 4.04. Events of Default.

     (a) On and after the Release Date, Section 601(8) of the Original Indenture
shall no longer apply to the Notes.

     For purposes of the Notes, Section 601(8) of the Original Indenture shall
read, "the occurrence of an "event of default" as such term is defined in the
Mortgage; or".

     (b) On and after the Release Date, if the Notes become secured by
Substitute Mortgage Bonds pursuant to Section 4.03 above, the occurrence of a
"default" (as defined in the Substitute Mortgage) shall constitute an Event of
Default under Section 601 of the Original Indenture with respect to the Notes
and the references in Section 601(4) of the Original Indenture and related
provisions to "Mortgage Bonds" shall be deemed to refer to "Substitute Mortgage
Bonds."

                                  ARTICLE FIVE

                            MISCELLANEOUS PROVISIONS

     THE DETROIT EDISON COMPANY, a corporation duly organized and existing under
the laws of the State of Michigan (the "Company", which term includes any
successor corporation under the Indenture hereinafter referred to), for value
received, hereby promises to pay to Cede & Co. or registered assigns, at the
office or agency of the Company in The City of New York, New York, the principal
sum of ____________________ ($_______) on June 1, 2036 (the "Stated Maturity"),
in the coin or currency of the United States, and to pay interest thereon from
the Original Issue Date shown above, or from the most recent Interest Payment
Date to which interest has been paid or duly provided for, in arrears on each
Interest Payment Date as specified above, commencing on December 1, 2006 and on

annum shown above (the "Interest Rate") until the principal hereof is due and
payable, and on any overdue principal and premium and on any overdue installment
of interest. The interest installment so payable, and punctually paid or duly
provided for, on any Interest Payment Date will, as provided in the Indenture,
be paid to the Person in whose name this Note (or one or more Predecessor
Securities) is registered on the Regular Record Date as specified above next
preceding such Interest Payment Date. Except as otherwise provided in the
Indenture, any such interest not so punctually paid or duly provided for will
forthwith cease to be payable to the Holder on such Regular Record Date and may
either be paid to the Person in whose name this Note (or one or more Predecessor
Securities) is registered at the close of business on a Special Record Date to
be fixed by the Trustee for the payment of such defaulted interest, notice
whereof shall be given to Holders of Notes of this series not less than ten days
prior to such Special Record Date, or may be paid at any time in any other
lawful manner not inconsistent with the requirements of any securities exchange,
if any, on which the Notes of this series shall be listed, and upon such notice
as may be required by any such exchange, all as more fully provided in the
Indenture.

     Payments of interest on this Note will include interest accrued to but
excluding the respective Interest Payment Dates. Interest payments for this Note
shall be computed and paid on the basis of a 360-day year of twelve 30-day
months. The Company shall pay interest on overdue principal and premium, if any,
and, to the extent lawful, on overdue installments of interest at the rate per
annum borne by this Note. In the event that any Interest Payment Date,
Redemption Date or Maturity Date is not a Business Day, then the required
payment of principal, premium, if any, and interest will be made on the next
succeeding day that is a Business Day (and without any interest or other payment
in respect of any such delay), in each case with the same force and effect as if
made on such date. "Business Day" means any day other than a day on which
banking institutions in the State of New York or the State of Michigan are
authorized or obligated pursuant to law or executive order to close.

     Payment of principal of, premium, if any, and interest on the Notes shall
be made in such coin or currency of the United States of America as at the time
of payment is legal tender for payment of public and private debts. Payments of
principal of, premium, if any, and interest on Notes represented by a Global
Security shall be made by wire transfer of immediately available funds to the
Holder of such Global Security, provided that, in the case of payments of
principal and premium, if any, such Global Security is first surrendered to the
Paying Agent (as defined in the Indenture). If any of the Notes of this series
are no longer represented by a Global Security, (i) payments of principal,
premium, if any, and interest due at the Stated Maturity or earlier redemption
of such Securities shall be made at the office of the Paying Agent upon
surrender of such Securities to the Paying Agent, and (ii) payments of interest
shall be made, at the option of the Company, subject to such surrender where
applicable, by check mailed to the address of the Person entitled thereto as
such address shall appear in the Security Register.

<PAGE>

THE NOTES TO THE TRUSTEE UNDER THE INDENTURE (THE "MORTGAGE"). ON THE RELEASE
DATE, THE NOTES SHALL CEASE TO BE SECURED BY SUCH MORTGAGE BONDS AND, AT THE
COMPANY'S OPTION, SHALL EITHER (1) BECOME UNSECURED GENERAL OBLIGATIONS OF THE
COMPANY OR (2) BE SECURED BY SUBSTITUTE MORTGAGE BONDS UNDER A SUBSTITUTE
MORTGAGE.

     This Note shall not be entitled to any benefit under the Indenture
hereinafter referred to, be valid or become obligatory for any purpose until the
Certificate of Authentication hereon shall have been signed by or on behalf of
the Trustee.

     Unless the Certificate of Authentication hereon has been executed by the
Trustee or a duly appointed Authentication Agent referred to herein, this Note
shall not be entitled to any benefit under the Indenture or be valid or
obligatory for any purpose.

     This Note is one of a duly authorized series of Securities of the Company
(herein sometimes referred to as the "Notes"), specified in the Indenture, all
issued or to be issued in one or more series under and pursuant to a Collateral
Trust Indenture dated as of June 30, 1993 (the "Original Indenture") duly
executed and delivered between the Company and J.P. Morgan Trust Company,
National Association, as successor Trustee (herein referred to as the
"Trustee"), as supplemented through and including a Twentieth Supplemental
Indenture dated as of May 15, 2006 (together with the Original Indenture, the
"Indenture") between the Company and the Trustee, to which Indenture and all
indentures supplemental thereto reference is hereby made for a description of
the respective rights, limitations of rights, obligations, duties and immunities
thereunder of the Trustee, the Company and the registered Holders of the Notes
and of the terms upon which the Notes are, and are to be, authenticated and
delivered.

     This Note is not subject to repayment at the option of the Holder hereof.
Except as provided below, this Note is not redeemable by the Company prior to
maturity and is not subject to any sinking fund.

     This Note will be redeemable at the option of the Company, in whole at any
time or in part from time to time (any such date of optional redemption, an
"Optional Redemption Date," which shall be a "Redemption Date" for purposes of
the Indenture), at an optional redemption price (which shall be a "Redemption
Price" for purposes of the Indenture) equal to the greater of (i) 100% of the
principal amount of this Note to be redeemed and (ii) the sum of the present
values of the remaining scheduled payments of principal and interest of this
Note to be redeemed (not including any portion of any payments of interest
accrued to the Optional Redemption Date) until Stated Maturity, in each case
discounted from their respective scheduled payment dates to such Optional
Redemption Date on a semiannual basis (assuming a 360-day year consisting of
30-day months) at the Adjusted Treasury Rate (as defined below) plus 30 basis
points, as determined by the Reference Treasury Dealer (as defined below), plus,
in each case, accrued and unpaid interest thereon to the Redemption Date.

     Notwithstanding the foregoing, installments of interest on this Note that
are due and payable on Interest Payment Dates falling on or prior to a
Redemption Date will be payable on the Interest Payment Date to the registered
Holders as of the close of business on the relevant Record Date.

     "Adjusted Treasury Rate" means, with respect to any Optional Redemption
Date, the rate per annum equal to the semiannual equivalent yield to maturity of
the Comparable Treasury


                                       A-3

<PAGE>

Issue, calculated on the third Business Day preceding such Optional Redemption
Date assuming a price for the Comparable Treasury Issue (expressed as a
percentage of its principal amount) equal to the Comparable Treasury Price for
such Optional Redemption Date.

     "Comparable Treasury Issue" means the United States Treasury security
selected by the Reference Treasury Dealer as having a maturity comparable to the
remaining term of this Note that would be utilized, at the time of selection and
in accordance with customary financial practice, in pricing new issues of
corporate debt securities of comparable maturity to the remaining term of this
Note.

     "Comparable Treasury Price" means, with respect to any Optional Redemption
Date, (i) the average of the Reference Treasury Dealer Quotations for such
Optional Redemption Date, after excluding the highest and lowest such Reference
Treasury Dealer Quotations, or (ii) if the Trustee obtains fewer than two such
Reference Treasury Dealer Quotations, the average of all such quotations, or
(iii) if only one Reference Treasury Dealer Quotation is received, such
quotation.

     "Reference Treasury Dealer" means each of: (i) Barclays Capital Inc.,
Citigroup Global Markets Inc., and J.P. Morgan Securities Inc. (or their
respective affiliates which are Primary Treasury Dealers), and their respective
successors; provided, however, that if any of the foregoing shall cease to be a
primary U.S. government securities dealer in the United States (a "Primary
Treasury Dealer"), the Company will substitute therefor another Primary Treasury
Dealer; and (ii) any other Primary Treasury Dealer(s) selected by the Trustee
after consultation with the Company.

     "Reference Treasury Dealer Quotation" means, with respect to each Reference
Treasury Dealer and any Optional Redemption Date, the average, as determined by
the Trustee, of the bid and asked prices for the Comparable Treasury Issue
(expressed in each case as a percentage of its principal amount) quoted in
writing to the Trustee by such Reference Treasury Dealer at 5:00 p.m., New York
City time, on the third Business Day preceding such Optional Redemption Date.

     Notice of any optional redemption will be mailed at least 30 days but not
more than 60 days before the Optional Redemption Date to the Holder hereof at
its registered address.

     If notice has been provided in accordance with the Indenture and funds for
the redemption of this Note called for redemption have been made available on
the Redemption Date, this Note will cease to bear interest on the date fixed for
redemption. Thereafter, the only right of the Holder hereof will be to receive
payment of the Redemption Price.

     The Company will notify the Trustee at least 60 days prior to giving notice
of redemption (or such shorter period as is satisfactory to the Trustee) of the
aggregate principal amount of Notes to be redeemed and the Redemption Date. If
the Company elects to redeem all or a portion of the Notes, the redemption will
be conditional upon receipt by the Paying Agent or the Trustee of monies
sufficient to pay the Redemption Price. If the Notes are only partially redeemed
by the Company, the Trustee shall select which Notes are to be redeemed in a
manner it deems fair and appropriate in accordance with the terms of the
Indenture.

     In the event of redemption of this Note in part only, a new Note or Notes
of this series for the unredeemed portion hereof will be issued in the name of
the registered Holder hereof upon the cancellation hereof.

     In case an Event of Default, as defined in the Indenture, shall have
occurred and be continuing, the principal of all of the Notes may be declared,
and upon such declaration shall become, due and payable, in the manner, with the
effect and subject to the conditions provided in the Indenture.

     The Indenture contains provisions for defeasance at any time of the entire
indebtedness of this Note upon compliance by the Company with certain conditions
set forth therein.

     The Indenture contains provisions permitting the Company and the Trustee,
with the consent of the registered Holders of not less than a majority in
aggregate principal amount of the outstanding Securities of each series affected
at the time, as defined in the Indenture, to execute supplemental indentures for
the purpose of adding any provisions to or changing in any manner or eliminating
any of the provisions of the Indenture or of any supplemental indenture or of
modifying in any manner the rights of the registered Holders of the Securities;
provided, however, that no such supplemental indenture shall (i) extend the
fixed maturity of any Securities of any series, or reduce the principal amount
thereof, or reduce the rate of or extend the time of payment of interest
thereon, or reduce any premium payable upon the redemption thereof, without the
consent of the registered Holder of each Security so affected or (ii) reduce the
aforesaid percentage of Securities, the registered Holders of which are required
to consent to any such supplemental indenture, without the consent of the
registered Holders of each Security then outstanding and affected thereby. The
Indenture also contains provisions permitting (i) the registered Holders of at
least 66 2/3% in aggregate principal amount of the Securities of all series at
the time outstanding affected thereby, on behalf of the registered Holders of
the Securities of such series, to waive compliance by the Company with certain
provisions of the Indenture and (ii) the registered Holders of a majority in
aggregate principal amount of the Securities of all series at the time
outstanding affected thereby, on behalf of the registered Holders of the
Securities of such series, to waive certain past defaults under the Indenture
and their consequences. Any such consent or waiver by the registered Holder of
this Note (unless revoked as provided in the Indenture) shall be conclusive and
binding upon such registered Holder and upon all future registered Holders and
owners of this Note and of any Note issued in exchange hereof or in place hereof
(whether by registration of transfer or otherwise), irrespective of whether or
not any notation of such consent or waiver is made upon this Note.

     No reference herein to the Indenture and no provision of this Note or of
the Indenture shall alter or impair the obligation of the Company, which is
absolute and unconditional, to pay the principal of and interest on this Note at
the time and place and at the rate and in the coin or currency herein
prescribed.

     Prior to the Release Date, the Notes of this series shall be secured by a
series of Mortgage Bonds (the "Related Series of Bonds"), delivered by the
Company to the Trustee for the benefit of the Holders of the Notes. Reference is
made to the Mortgage and the Indenture for a description of the rights of the
Trustee as Holder of the Related Series of Bonds, the property mortgaged and
pledged under the Mortgage and the rights of the Company and of the Mortgage
Trustee in respect thereof, the duties and immunities of the Mortgage Trustee
and the terms and conditions upon which the Related Series of Bonds are secured
and the circumstances under which additional Mortgage Bonds may be issued.

     FROM AND AFTER SUCH TIME AS ALL BONDS, OTHER THAN (1) PLEDGED BONDS,
INCLUDING THE RELATED SERIES OF BONDS, AND (2) MORTGAGE BONDS


                                       A-5

<PAGE>

(EXCLUSIVE OF PLEDGED BONDS) WHICH DO NOT IN AGGREGATE PRINCIPAL AMOUNT EXCEED
THE GREATER OF FIVE PERCENT (5%) OF NET TANGIBLE ASSETS OR FIVE PERCENT (5%) OF
CAPITALIZATION, HAVE BEEN RETIRED THROUGH PAYMENT, REDEMPTION OR OTHERWISE
(INCLUDING THOSE MORTGAGE BONDS THE PAYMENT FOR WHICH HAS BEEN PROVIDED FOR IN
ACCORDANCE WITH THE MORTGAGE) AT, BEFORE OR AFTER THE MATURITY THEREOF, PROVIDED
THAT NO DEFAULT OR EVENT OF DEFAULT HAS OCCURRED AND IS CONTINUING (THE "RELEASE
DATE"), THE RELATED SERIES OF BONDS SHALL CEASE TO SECURE THE NOTES IN ANY
MANNER.

     As provided in the Indenture and subject to certain limitations therein set
forth, the transfer of this Note is registrable in the Security Register of the
Company, upon surrender of this Note for registration of transfer at the office
or agency of the Company in any place where the principal of and any interest on
this Note are payable or at such other offices or agencies as the Company may
designate, duly endorsed by or accompanied by a written instrument or
instruments of transfer in form satisfactory to the Company and the Security
Registrar or any transfer agent duly executed by the registered Holder hereof or
his or her attorney duly authorized in writing, and thereupon one or more new
Notes of this series and of like tenor, of authorized denominations and for the
same aggregate principal amount will be issued to the designated transferee or
transferees. No service charge will be made for any such transfer, but the
Company may require payment of a sum sufficient to cover any tax or other
governmental charge payable in relation thereto.

     Prior to due presentment for registration of transfer of this Note, the
Company, the Trustee, any Paying Agent and any Note Registrar may deem and treat
the registered Holder hereof as the absolute owner hereof (whether or not this
Note shall be overdue and notwithstanding any notice of ownership or writing
hereon made by anyone other than the Note Registrar) for the purpose of
receiving payment of or on account of the principal hereof and interest due
hereon and for all other purposes, and neither the Company nor the Trustee nor
any Paying Agent nor any Security Registrar shall be affected by any notice to
the contrary.

     The Notes of this series are issuable only in fully registered form without
coupons in denominations of $1,000 and any integral multiple thereof. This
Global Security is exchangeable for Notes in definitive form only under certain
limited circumstances set forth in the Indenture. As provided in the Indenture
and subject to certain limitations therein set forth, Notes of this series are
exchangeable for a like aggregate principal amount of Notes of this series of a
different authorized denomination, as requested by the registered Holder
surrendering the same.

     As set forth in, and subject to the provisions of, the Indenture, no Holder
of any Note will have any right to institute any proceeding with respect to the
Indenture or for any remedy thereunder, unless (i) such Holder shall have
previously given to the Trustee written notice of a continuing Event of Default
with respect to the Notes of this series, (ii) the Holders of not less than 25%
in principal amount of the outstanding Notes of this series shall have made
written request, and offered reasonable indemnity, to the Trustee to institute
such proceeding as trustee, (iii) the Trustee shall have failed to institute
such proceeding within 60 days and (iv) the Trustee shall not have received from
the Holders of a majority in principal amount of the outstanding Notes of this
series a direction inconsistent with such request within such 60-day period;
provided, however, that such limitations do not apply to a suit instituted by
the Holder hereof for


                                       A-6

the enforcement of payment of the principal of or any interest on this Note on
