                        TITLE AND TERMS OF THE SECURITIES

         SECTION 201 Title of the Securities; Stated Maturity. This Supplemental
Indenture hereby establishes a separate series of Securities, which shall be
known as the Company's "   % Senior Notes due 2007" (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 August 16, 2007.

         SECTION 202 Rank. The Notes shall rank equally with all other unsecured
and unsubordinated indebtedness of the Company from time to time outstanding.

         SECTION 203 Variations from the Original Indenture. Section 1009 of the
Original Indenture shall be applicable to the Notes. Section 403(2) and Section
403(3) of the Original Indenture shall be applicable to the Notes; the Company's
obligations under Section 1009 of the Original Indenture, without limitation,
shall be subject to defeasance in accordance with Section 403(3) of the Original
Indenture.

         SECTION 204 Amount.

         (a)    The aggregate principal amount of Notes that may be issued under
this Supplemental Indenture is limited (except as provided in Section 301(2) of
the Original Indenture) initially to $    (or, $    , if the underwriters'

Outstanding Notes, "reopen" the Notes so as to increase the aggregate principal
amount of such 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 tenor and terms (including, without
limitation, rights 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 series of Notes.


                                       5







         SECTION 205 Form and Denominations of Securities.

         (a)    Except as provided in Section 205(b), the Notes shall be
issuable only in certificated, fully registered form and, as permitted by
Section 301 and Section 302 of the Original Indenture, in denominations of $25
and integral multiples thereof. The entire principal amount of the Notes shall
initially be evidenced by one or more certificates issued to The Bank of New
York, as Purchase Contract Agent pursuant to the Purchase Contract Agreement.

         (b)    Separate Notes shall be issued in the form of one or more global
certificates (the "Global Notes") under a book-entry system, registered in the
name of The Depository Trust Company, as depositary ("DTC"), or its nominee,
which is hereby designated as "U.S. Depositary" and "Depositary" under the
Indenture for the Global Notes. Each such certificated Note and Global Note
shall represent such aggregate principal amount of the Outstanding Notes as
shall be from time to time endorsed thereon, which principal amounts may be
increased or decreased, as applicable, to reflect, in connection with the
creation of Stripped Equity Security Units and the recreation of Equity Security
Units, transfers between Pledged Notes and Separate Notes. Any such increase or
decrease in the aggregate principal amount of (i) certificated Notes shall be
made by the Collateral Agent and (ii) Global Notes shall be made by the Trustee,
as custodian of the Global Notes, in each case upon the instructions of the
Collateral Agent given pursuant to Article IV of the Pledge Agreement.

         (c)    Further to Section 305 of the Original Indenture, any Global
Note shall be exchangeable for certificated Notes without coupons registered in
the name of, and a transfer of a Global Note may be registered to, any Person
other than the Depositary for such Note or its nominee only (x) as provided in
Section 205(b) or if (y) (i) such Depositary notifies the Company that it is
unwilling or unable to continue as Depositary for such Global Note and no
successor Depositary has been appointed within 90 days after this notice, (ii)
the Depositary at any time ceases to be a Depositary registered under the
Exchange Act at which time the Depositary is required to be so registered to act
as the Depositary and no successor Depositary has been appointed within 90 days
after the Company learns that the Depositary has ceased to be so registered,
(iii) the Company determines in its sole discretion that it will no longer have
the Notes represented by Global Notes or permit any of the Global Note
certificates to be so exchangeable or (iv) an Event of Default with respect to
the Notes under the Indenture has occurred and is continuing. Upon the
occurrence in respect of any Global Note of any or more of the conditions
specified in clause (y) (i), (ii), (iii) or (iv) of the preceding sentence, the
Company will execute, and subject to Article Three of the Original Indenture,
the Trustee, upon written notice from the Company, will authenticate and deliver
the Notes in definitive registered form without coupons, in authorized
denominations in exchange for such Global Note or applicable portion thereof.
Upon exchange of a Global Note as a whole for Notes in definitive registered
form without coupons, in authorized denominations, the Global Note shall be
cancelled by the Trustee. Such Notes in definitive registered form issued in
exchange for the Global Note shall be registered in such names and in such
authorized denominations and delivered as the Depositary, pursuant to
instructions from its direct or indirect participants or otherwise, shall
instruct the Trustee.


                                       6



         SECTION 206 Interest.

         (a)    Each Note will bear interest initially at the rate of  % per
year (the "Coupon Rate") from the original date of issuance through and
including the day immediately preceding the Reset Effective Date and at the
Reset Rate thereafter until the principal thereof is paid or duly made available
for payment and shall bear interest, to the extent permitted by law, compounded
quarterly, on any overdue principal and premium, if any, and on any overdue
installment of interest at the Coupon Rate through and including the day
immediately preceding the Reset Effective Date and at the Reset Rate thereafter,
payable quarterly in arrears on February 16, May 16, August 16 and November 16
of each year (each, an "Interest Payment Date") commencing on August 16, 2002.
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) is registered at the close of business on the relevant
record date for such interest installment, which shall be the close of business
on the first day of the month (whether or not a Business Day) in which such
Interest Payment Date falls (the "Regular Record Date"). Any such interest
installment not 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 applicable series of
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.

         (b)    The amount of interest payable for any period will be computed
(i) for any full quarterly period on the basis of a 360-day year of twelve
30-day months and (ii) for any period shorter than a full quarterly period, on
the basis of a 30-day month and, for periods of less than a month, on the basis
of the actual number of days elapsed per 30-day month. If any Interest Payment
Date, redemption date or other date of Maturity of the Notes is not a Business
Day, the payment of the interest payable on that date will be made on the next
day that is a Business Day, without any interest or other payment in respect of
the delay, except that if the next Business Day is in the next calendar year,
then the payment will be made on the immediately preceding Business Day, in each
case with the same force and effect as if made on the scheduled payment date.

         (c)    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 which 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 or by wire transfer to the
account designated to the Trustee by a prior written notice by such Holder
delivered at least five Business Days prior to the applicable Interest Payment
Date.


                                       7






         SECTION 207 Remarketing and Reset Rate.

         (a)    The interest rate on the Notes will be reset on the Remarketing
Date to the applicable Reset Rate. In the event of a failed remarketing on the
Remarketing Date, the interest rate on the Notes will be reset on a Subsequent
Remarketing Date. In the event that there is a Last Failed Remarketing on the
fifth Business Day immediately preceding August 16, 2005, the interest rate on
the Notes will be reset in accordance with the provisions of Section 207(e).

         (b)(i) The Company shall engage a nationally recognized investment bank
(the "Remarketing Agent") pursuant to the Remarketing Agreement to be mutually
agreed on by the Company, the Agent and the Remarketing Agent, but substantially
as set forth in Exhibit D hereto, to sell the Notes of holders of Equity
Security Units and of Holders of Notes that are not held as part of the Equity
Security Units ("Separate Notes") that have elected to participate in the
remarketing pursuant to the procedures set forth in Section 207(c). On the
seventh Business Day immediately preceding the first Business Day of any
Remarketing Period, the Remarketing Agent shall give Holders of Separate Notes
notice of the remarketing (the form of which notice to be provided by the
Company) in a daily newspaper in the English language of general circulation in
The City of New York, which is expected to be The Wall Street Journal. Pursuant
to the terms of the Purchase Contract Agreement, the Purchase Contract Agent
shall notify, by 10:00 a.m., New York City time, on the third Business Day
preceding the first Business Day of any Remarketing Period, the Remarketing
Agent and the Collateral Agent of the aggregate number of Notes of Equity
Security Unit holders to be remarketed. Pursuant to the terms of the Purchase
Contract Agreement, on the third Business Day immediately preceding the first
Business Day of any Remarketing Period, no later than by 10:00 a.m. New York
City time, pursuant to the terms of the Pledge Agreement, the Custodial Agent
will notify the Remarketing Agent of the aggregate number of Separate Notes to
be remarketed. On the third Business Day immediately preceding the first
Business Day of any Remarketing Period, the Collateral Agent and the Custodial
Agent, pursuant to the terms of the Pledge Agreement, will deliver for
remarketing to the Remarketing Agent all Notes to be remarketed. Pursuant to the
terms of the Remarketing Agreement, upon receipt of such notice from the
Custodial Agent and such Notes from the Collateral Agent and the Custodial
Agent, the Remarketing Agent will, on the Remarketing Date and on any Subsequent
Remarketing Date in accordance with the provisions of Section 207(b)(ii), use
its commercially reasonable best efforts to (x) establish a rate of interest
that, in the opinion of the Remarketing Agent, will, when applied to the Notes
included in the remarketing, enable the then current aggregate market value of
the Notes to have a value equal to approximately, but not less than, 100.50% of
the Remarketing Value as of the Remarketing Date or as of any Subsequent
Remarketing Date, as the case may be (the "Reset Rate") and (y) sell such Notes
on such date at a price equal to approximately, but not less than, 100.50% of
the Remarketing Value. Pursuant to the terms of the Remarketing Agreement, the
Remarketing Agent will deduct as a remarketing fee an amount not exceeding 25
basis points (0.25%) of the total proceeds from the remarketing (the
"Remarketing Fee"). Pursuant to the terms of the Remarketing Agreement, the
Remarketing Agent will use the remaining proceeds from the successful
remarketing to purchase the appropriate U.S. Treasury securities (the "Treasury
Portfolio") (with the CUSIP numbers, if any, selected by the Remarketing Agent)
described in clauses (i) and (ii) of the definition of Remarketing Value related
to the Notes of holders of Equity Security Units that were remarketed. Pursuant
to the terms of the Purchase Contract Agreement, on or prior to the third
Business Day following the Remarketing Date (or in


                                       8




the event that the Notes are not successfully remarketed on the Remarketing
Date, on or prior to the third Business Day immediately following the applicable
Subsequent Remarketing Date), the Remarketing Agent shall deliver such Treasury
Portfolio to the Purchase Contract Agent, which shall thereupon deliver such
Treasury Portfolio to the Collateral Agent. The Collateral Agent, for the
benefit of the Company, will thereupon apply such Treasury Portfolio, in
accordance with the Pledge Agreement, to secure such holders' obligations under
the Purchase Contracts. Pursuant to the terms of the Purchase Contract
Agreement, the Remarketing Agent will remit (1) the portion of the proceeds from
the remarketing attributable to the Separate Notes to the Holders of Separate
Notes that were remarketed and (2) the remaining portion of the proceeds, less
those proceeds used to purchase the Treasury Portfolio, to the holders of the
Equity Security Units that were remarketed, all determined on a pro rata basis,
in each case, net of the remarketing fee, on or prior to the third Business Day
following the Remarketing Date (or in the event that the Notes are not
successfully remarketed on the Remarketing Date, on or prior to the third
Business Day immediately following the applicable Subsequent Remarketing Date
for a successful remarketing). Holders whose Notes are so remarketed will not
otherwise be responsible for the payment of any Remarketing Fee in connection
therewith.

                (ii) Pursuant to the terms of the Remarketing Agreement, if, in
spite of using its commercially reasonable best efforts, the Remarketing Agent
cannot establish the Reset Rate and remarket the Notes included in the
remarketing at a price equal to approximately, but not less than, 100.50% of the
Remarketing Value on the Remarketing Date, the Remarketing Agent will attempt to
again establish the Reset Rate and remarket the Notes included in the
remarketing at a price equal to approximately, but not less than, 100.50% of the
Remarketing Value on each of the two immediately following Business Days.
Pursuant to the terms of the Remarketing Agreement, if the Remarketing Agent
cannot remarket the Notes included in the remarketing at a price equal to
approximately, but not less than, 100.50% of the Remarketing Value on either of
those days, it will attempt to establish the Reset Rate and remarket the Notes
included in the remarketing at a price equal to approximately, but not less
than, 100.50% of the Remarketing Value on each of the three Business Days
immediately preceding July 1, 2005. Pursuant to the terms of the Remarketing
Agreement, if the Remarketing Agent cannot establish the Reset Rate and remarket
the Notes included in the remarketing at a price equal to approximately, but not
less than, 100.50% of the Remarketing Value on any of the three Business Days
immediately preceding July 1, 2005, the Remarketing Agent will further attempt
to establish the Reset Rate and remarket the Notes included in the remarketing
at a price equal to approximately, but not less than, 100.50% of the Remarketing
Value on each of the seventh, sixth and fifth Business Days immediately
preceding the Stock Purchase Date. If the Remarketing Agent cannot establish the
Reset Rate and remarket the Notes included in the remarketing at a price equal
to approximately, but not less than, 100.50% of the Remarketing Value on any of
the Remarketing Date or the two Business Days immediately following the
Remarketing Date, on any of the three Business Days immediately preceding July
1, 2005 or on the seventh or sixth or fifth Business Day immediately preceding
the Stock Purchase Date, the remarketing on each such date will be deemed to
have failed (each, a "Failed Remarketing"). In addition, if, in spite of using
its commercially reasonable best efforts, the Remarketing Agent fails to
remarket the Notes included in the remarketing at 100.50% of the Remarketing
Value in accordance with the terms of the Pledge Agreement by 4:00 p.m., New
York City time, on the last Business Day in a Remarketing Period, a "Last Failed
Remarketing" will be deemed to have occurred for that Remarketing Period.
Pursuant to the terms of the Remarketing Agreement, within three


                                       9






Business Days following the date of any Last Failed Remarketing, the Remarketing
Agent shall return any Notes delivered to it to the Collateral Agent. In the
event of a Last Failed Remarketing on the fifth Business Day immediately
preceding the Stock Purchase Date, (1) the Reset Rate on the Notes will be
determined as set forth in Section 207(e) and (2) an event of default shall be
deemed to have occurred under the Purchase Contract Agreement and the Pledge
Agreement and in accordance with the terms of the Pledge Agreement, the
Collateral Agent, for the benefit of the Company, shall, in respect of the Notes
comprising components of Equity Security Units, exercise its rights as a secured
party with respect to such Notes, including those actions specified in Section
207(b)(iii); provided, that if upon a Last Failed Remarketing on the fifth
Business Day immediately preceding the Stock Purchase Date, the Collateral Agent
delivers a Note to the Company in full satisfaction of the Equity Security Unit
holder's obligation under the related Purchase Contract, any accrued and unpaid
interest on such Note will become payable by the Company to the Purchase
Contract Agent for payment to the holder of the Equity Security Units to which
such Note relates. Such payment will be made by the Company on or prior to 11:00
a.m., New York City time, on the Stock Purchase Date in lawful money of the
United States of America by certified or cashier's check or wire transfer in
immediately available funds payable to or upon the order of the Purchase
Contract Agent. Pursuant to the terms of the Purchase Contract Agreement, the
Company will cause a notice of any Last Failed Remarketing to be published on
the fourth Business Day following the last Business Day comprising the related
Remarketing Period in a daily newspaper in the English language of general
circulation in The City of New York, which is expected to be The Wall Street
Journal. The Company will also release this information by means of Bloomberg
and Reuters newswire. In addition, the Company will request, not later than
seven nor more than 15 calendar days prior to any Remarketing Period, that the
Depositary notify its participants holding Notes of the remarketing.

                (iii) With respect to any Notes that constitute part of Equity
Security Units that are subject to a Last Failed Remarketing on the fifth
Business Day immediately preceding the Stock Purchase Date, the Collateral Agent
for the benefit of the Company reserves all of its rights as a secured party
with respect thereto and, subject to applicable law and Section 5.4(e) of the
Purchase Contract Agreement, may, among other things, permit the Company to
cause the Notes to be sold or to retain and cancel such Notes, in either case,
in full satisfaction of the Equity Security Unit holders' obligations under the
Purchase Contracts.

                (iv) The right of each Holder of Pledged Notes or Separate Notes
to have Notes included in any remarketing shall be limited to the extent that
(i) the Remarketing Agent conducts a remarketing on the Remarketing Date or on
any Subsequent Remarketing Date, as the case may be, pursuant to the terms of
the Remarketing Agreement, (ii) the Notes included in a remarketing have not
been called for redemption, (iii) the Remarketing Agent is able to find a
purchaser or purchasers for the Notes included in a remarketing at a Reset Rate
such that the then current aggregate market value of the Notes is equal to
approximately, but not less than, 100.50% of the Remarketing Value, and (iv)
such purchaser or purchasers deliver the purchase price therefor to the
Remarketing Agent as and when required.

         In accordance with the Depositary's normal procedures, the transactions
described above with respect to each Note tendered for purchase and sold in any
successful remarketing shall be executed through the Depositary, and the
accounts of the respective Clearing Agency Participants shall be debited and
credited and such Notes delivered by book entry as necessary to



                                       10






effect purchases and sales of such Notes. The Depositary shall make payment in
accordance with its normal procedures.

         If any Holder selling Notes in any successful remarketing fails to
deliver such Notes, the Clearing Agency Participant of such selling Holder and
of any other Person that was to have purchased Notes in such successful
remarketing may deliver to any such other Person an aggregate principal amount
of Notes that is less than the aggregate principal amount of Notes that
otherwise was to be purchased by such Person. In such event, the aggregate
principal amount of Notes to be so delivered shall be determined by such
Clearing Agency Participant, and delivery of such lesser aggregate principal
amount of Notes shall constitute good delivery.

         The Remarketing Agent is not obligated to purchase any Notes in any
remarketing or otherwise. Neither the Trustee, the Company nor the Remarketing
Agent shall be obligated in any case to provide funds to make payment upon
tender of Notes for remarketing.

         The tender and settlement procedures set forth in this Section 207(b),
including provisions for payment by purchasers of Notes in any successful
remarketing, shall be subject to modification, notwithstanding any provision to
the contrary set forth herein, to the extent required by the Depositary or if
the book-entry system is no longer available for the Notes at the time of any
successful remarketing, to facilitate the tendering and remarketing of Notes in
certificated form. In addition, the Remarketing Agent may, notwithstanding any
provision to the contrary set forth herein, modify the settlement procedures set
forth herein in order to facilitate the settlement process.

         (c)    Prior to 11:00 a.m., New York City time, on the fourth Business
Day immediately preceding the first Business Day of a remarketing period,
Holders of Separate Notes may elect to have their Notes participate in the
remarketing by delivering their Notes along with a notice of such election
(substantially in the form of Exhibit C to the Pledge Agreement) to the
Collateral Agent (in its capacity as Custodial Agent). The Collateral Agent (in
its capacity as Custodial Agent) will hold these Notes in an account separate
from the collateral account in which the securities pledged to secure the
Holders' obligations under the Purchase Contracts will be held. Holders of
Separate Notes electing to have their Notes remarketed will also have the right
to withdraw that election on or prior to the fifth Business Day immediately
preceding the first day of the relevant remarketing period by delivering a
notice of such election (substantially in the form of Exhibit D to the Pledge
Agreement) to the Collateral Agent (in its capacity as Custodial Agent).

         (d)    In the event that the Reset Rate is established on a Remarketing
Date or a Subsequent Remarketing Date, the Remarketing Agent will advise the
Depositary, the Trustee and the Company of the Reset Rate by approximately 4:30
p.m., New York City time, on such date. The Company will, on the second Business
Day immediately preceding the Reset Effective Date or as soon as is practicable
thereafter, cause a notice of the Reset Rate applicable to the Notes to be
published in a daily newspaper in the English language of general circulation in
The City of New York, which is expected to be The Wall Street Journal. The
Company will also release this information by such date by means of Bloomberg
and Reuters newswire.


                                       11





         (e)    In the event of a Last Failed Remarketing on the fifth Business
Day immediately preceding the Stock Purchase Date, the Reset Rate shall be
determined as follows. In accordance with the provisions of the Remarketing
Agreement, the Remarketing Agent shall establish the Reset Rate by taking the
average of the interest rates quoted to it by three nationally recognized
investment banks selected by the Company, which are underwriters or dealers in
debt securities similar to the Notes, that in its judgment reflect an accurate
market rate of interest applicable to the Notes at that time. Following receipt
of these quotes, the Remarketing Agent will have the right, in its sole
judgment, to either recalculate the average based on only two of the quoted
interest rates if one of the three quotes, in the Remarketing Agent's sole
discretion, does not reflect market conditions or, alternatively, determine a
consensus among the investment banks rather than a strict mathematical average
by taking into account relevant qualitative and quantitative factors. These
factors may include, but shall not be limited to, maturity of the Notes, the
Company's credit rating and the Company's credit risk and the credit rating and
credit risk of companies in similar industries, the then yield to maturity of
the Notes and the state of the market for primary and secondary sales of similar
debt securities. If for whatever reason the Remarketing Agent is unable to
establish the Reset Rate in accordance with the foregoing procedures, the Reset
Rate shall be rate of interest payable on the Notes on their original date of
issue.

         In accordance with the provisions of the Remarketing Agreement, the
Remarketing Agent will advise the Depositary, the Trustee and the Company of the
Reset Rate by approximately 4:30 p.m., New York City time, on August 16, 2005.
The Company shall, on the following Business Day or as soon as is practicable
thereafter, cause a notice of the Reset Rate to be published in a daily
newspaper in the English language of general circulation in The City of New
York. The Company will also release this information by such date by means of
Bloomberg and Reuters newswire.

         (f)    The Reset Rate established pursuant to the terms of this Section
207 shall be effective as of the Reset Effective Date.

         SECTION 208 Redemption.

         The Notes are not subject to repayment at the option of the Holders
thereof. If a Tax Event shall occur and be continuing, the Company may, at its
option, redeem the Notes, in whole but not in part, at any time at a price per
Note equal to the Redemption Price. Installments of interest on Notes which are
due and payable on or prior to the Tax Event Redemption Date will be payable to
Holders of the Notes registered as such at the close of business on the relevant
Regular Record Dates. If, following the occurrence of a Tax Event prior to the
earlier of (i) a successful remarketing of the Notes pursuant to the Remarketing
Agreement or (ii) the Stock Purchase Date, the Company exercises its option to
redeem the Notes, the Company shall appoint the Quotation Agent to assemble the
Tax Event Treasury Portfolio.

         Notice of any redemption will be mailed at least 30 days but not more
than 60 days before the Tax Event Redemption Date to each registered Holder of
Notes to be redeemed at its registered address. Payment of the Redemption Price
to each Holder of Notes shall be made by the Company no later than 12:00 noon,
New York City time, on the Tax Event Redemption Date, by check or wire transfer
in immediately available funds at such place and to such account as


                                       12


may be designated by each such Holder of Notes, including the Custodial Agent or
the Collateral Agent, as the case may be. Unless the Company defaults in payment
of the Redemption Price, on and after the Tax Event Redemption Date interest
shall cease to accrue on the Notes. In the event any Notes are called for a Tax
Event Redemption, on and after the date notice is given or deemed given in
accordance with the Original Indenture, neither the Company nor the Trustee will
be required to register the transfer of or exchange the Notes to be redeemed.

         Except as modified hereby or in the form of the Notes, redemptions
shall be effected in accordance with Article Eleven of the Original Indenture.

         SECTION 209 Sinking Fund.  The Notes are not subject to any sinking
fund.

         SECTION 210 Other Provisions.

         (a)    Each Note will initially be pledged to secure the Holder's
obligations under the Purchase Contract, pursuant to the terms and conditions
set forth in the Pledge Agreement.

         (b)    The Company agrees, and by acceptance of a beneficial ownership
interest in the Notes, each beneficial owner of Notes will be deemed to have
agreed (1) to treat the acquisition of an Equity Security Unit as the
acquisition of the Note and the Purchase Contract constituting the Equity
Security Unit and to allocate the purchase price of the Equity Security Unit
between the Note and the Purchase Contract as $25 and $0, respectively, (2) to
treat the Notes as indebtedness that is subject to Treas. Reg. Sec. 1.1275-4
(the "Contingent Payment Regulations") for United States federal income tax
purposes and (3) to be bound by the Company's determination of the "comparable
yield" and "projected payment schedule," within the meaning of the Contingent
Payment Regulations, with respect to the Notes for United States federal income
tax purposes. A Holder of Notes may obtain the amount of original issue
discount, issue date, yield to maturity, comparable yield and projected payment
schedule by submitting a written request for it to the Company at the following
address: DTE Energy Company, 2000 2nd Avenue, Detroit, Michigan 48226-1279,
Attn:  .

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

         SECTION 211 Form of Notes.  Attached hereto as Exhibit A is the form of
the Notes.

                                 ARTICLE THREE

                            MISCELLANEOUS PROVISIONS

Number: R-

         DTE Energy Company, a Michigan corporation (the "Company", which term
includes any successor corporation under the Indenture hereafter referred to),
for value received, hereby promises to pay to [For inclusion in Global Notes
only -- Cede & Co.] [For inclusion in Pledged Note -- The Bank of New York, as
Purchase Contract Agent pursuant to the Purchase Contract Agreement (as defined
below)] or registered assigns, the principal sum of $_______ or such other
principal sum as is reflected in the Schedule of Increases or Decreases attached
hereto on August 16, 2007, and to pay interest thereon from  , 2002, or from the
most recent Interest Payment Date to which interest has been paid or duly
provided for, quarterly in arrears on February 16, May 16, August 16 and
November 16 of each year (each, an "Interest Payment Date"), commencing August
16, 2002; initially at the rate of  % per annum through and including the day
immediately preceding the Reset Effective Date and at the Reset Rate thereafter
until the principal hereof shall have been paid or duly made available for
payment and, to the extent permitted by law, to pay interest, compounded
quarterly, on any overdue principal and premium, if any, and on any overdue
installment of interest at the rate per year of  % through and including the day
immediately preceding the Reset Effective Date and at the Reset Rate thereafter.
The amount of interest payable for any period will be computed (1) for any full
quarterly period on the basis of a 360-day year of twelve 30-day months and (2)
for any period shorter than a full quarterly period, on the basis of a 30-day
month and (3) for periods of less than a month, on the basis of the actual
number of days elapsed per 30-day month.


                                      A-1




         In the event that any date on which interest or principal is payable on
this Note is not a Business Day, then payment of interest or principal payable
on such date 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), except
that, if the Business Day is in the next succeeding calendar year, then the
payment will be made on the immediately preceding Business Day, in each case
with the same force and effect as if made on such payment date. The interest
installment so payable, and punctually paid or duly provided for, on any
Interest Payment Date with respect to this Note will, as provided in the
Indenture (as defined below), be paid to the person in whose name this Note (or
one or more Predecessor Securities, as defined in the Indenture) is registered
at the close of business on the Regular Record Date for such interest
installment which shall be the close of business on the first day of the month
(whether or not a Business Day) in which such Interest Payment Date falls (the
"Regular Record Date").

         Any such interest installment not 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 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 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 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 which 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 or by wire transfer to the account
designated to the Trustee by a prior written notice by such Holder delivered at
least five Business Days prior to the applicable Interest Payment Date.
Notwithstanding anything else contained herein, if this Note is a Global Note
and is held in book-entry form through the facilities of the Depositary,
payments on this Note will be made to the Depositary or its nominee in
accordance with arrangements then in effect between the Trustee and the
Depositary.

         Notwithstanding anything herein or in the Indenture to the contrary,
the Reset Rate shall in no event exceed the maximum rate, if any, permitted by
applicable law.

This Note is one of a duly authorized series of Securities of the Company,
designated as the "   % Senior Notes due 2007" (the "Notes"), initially limited
to an aggregate principal amount of $  (or   if the underwriters' over-allotment
option pursuant to the Underwriting Agreement is exercised in full) (except for
Notes authenticated and delivered upon transfer of, or in exchange for, or in
lieu of other Notes, and except as further provided in the Indenture), all
issued or to be issued under and pursuant to an Amended and Restated Indenture,
dated as of April 9, 2001, as supplemented by the Sixth Supplemental Indenture
dated as of  , 2002 (together, as amended, supplemented or modified, the
"Indenture"), duly executed and delivered between the Company and The Bank of
New York, a New York banking corporation, as Trustee (herein referred to as the
"Trustee", which term includes any successor trustee under the



                                      A-2



Indenture), to which Indenture 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.

         The Notes shall be redeemable in whole, but not in part, at any time at
the option of the Company if a Tax Event occurs and is continuing at a price per
Note equal to the Redemption Price. Subject to the terms of the Purchase
Contract Agreement and the Pledge Agreement with respect to Notes comprising
part of the Equity Security Units, the Redemption Price shall be paid to or on
behalf of each Holder of the Notes by the Company, no later than 12:00 noon, New
York City time, on the Tax Event Redemption Date, by check or wire transfer in
immediately available funds, at such place and to such account as may be
designated by each such Holder, including the Custodial Agent or the Collateral
Agent.

         Notice of any redemption must be given at least 30 days but not more
than 60 days before the Tax Event Redemption Date to each Holder of Notes to be
redeemed at its registered address. If money sufficient to pay the Redemption
Price of the Notes to be redeemed on the Tax Event Redemption Date is deposited
on or before the Tax Event Redemption Date and the other conditions set forth in
the Indenture are satisfied, then on and after such date, interest will cease to
accrue on the Notes called for redemption.

         In case an Event of Default with respect to the Notes shall have
occurred and be continuing, the principal hereof and accrued interest hereon 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 permits, with certain exceptions as therein provided, the
amendment thereof and the modification of the rights and obligations of the
Company and the rights of the Holders of the Notes under the Indenture at any
time by the Company and the Trustee with the consent of the Holders of a
majority of the aggregate principal amount of all Notes issued under the
Indenture at the time outstanding and affected thereby; provided, however, that
no such amendment shall without the consent of the Holder of each Note so
affected, among other things (i) change the stated maturity of the principal of,
or any installment of principal of or interest on any Notes of any series, or
reduce the principal amount thereof, or reduce the rate of interest thereon, or
reduce any premium payable upon the redemption thereof or (ii) reduce the
percentage of Notes, the Holders of which are required to consent to any
amendment or waiver or for certain other matters as set forth in the Indenture.
The Indenture also contains provisions permitting (i) the registered Holders of
66 2/3% in aggregate principal amount of the Securities of each 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



                                      A-3



Indenture and (ii) the registered Holders of not less than a majority in
aggregate principal amount of the Securities of any 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 premium, if any, and
interest on this Note in the manner, at the respective times, at the rate and in
the coin or currency herein prescribed.

         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 Security 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 Security 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 $25 and any integral multiple thereof.

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
registered owner of any Note will have any right to institute any proceeding
with respect to the Indenture or for any remedy thereunder, unless (i) such
registered owner 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 registered owners 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 registered owners
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
registered owner hereof for the enforcement of payment of the principal of or
premium, if any, or any interest on this Note on or after the respective due
dates expressed herein.

         No recourse may be taken, directly or indirectly, against any
incorporator, subscriber to the capital stock, stockholder, officer, director or

Company or the Trustee with respect to the Company's obligations on the
Securities or the obligations of the Company or the Trustee under the Indenture
or any certificate or other writing delivered in connection therewith.
