                         Indenture; then, upon receipt by the Trustee of a written
                         demand by Ambac, accompanied by a certification from the
                         Trustee as to the amount and type (principal, interest or
                         both) of payment by AMBAC ("Payment Demand") the bonds of
                         2001 Series AP shall be payable or redeemable, or both, in
                         an amount corresponding to the amount payable upon the
                         redemption of the Series 1992-CC Bonds, together in the case
                         of each of clause (1) and (2) above, with interest thereon
                         to the date of payment as provided below. The Trustee shall,
                         within five days after receiving such Payment Demand, mail a
                         copy thereof to the Company marked to indicate the date of
                         its receipt by the Trustee. Promptly upon receipt by the
                         Company of such copy of a Payment Demand, the Company shall
                         be obligated to pay such amount as may be deemed to be
                         interest and shall fix a date on which it will redeem the
                         bonds of said series so demanded to be redeemed (hereinafter
                         called the "Demand Redemption Date"). Interest shall accrue
                         to the date of payment. Notice of the date fixed as the
                         Demand Redemption Date shall be mailed by the Company to the
                         Trustee at least ten days prior to such Demand Redemption
                         Date. The date to be fixed by the Company as and for the
                         Demand Redemption Date may be any date up to and including
                         the earlier of (x) the 60th day after receipt by the Trustee
                         of the Payment Demand or (y) the maturity date of such bonds
                         first occurring following the 20th day after the receipt by
                         the Trustee of the Payment Demand; provided, however, that
                         if the Trustee shall not have received such notice fixing
                         the Demand Redemption Date on or before the 10th day
                         preceding the earlier of such dates, the Demand Redemption
                         Date shall be deemed to be the earlier of such dates. The
                         Trustee shall mail notice of the Demand Redemption Date
                         (such notice being hereinafter called the "Demand Redemption
                         Notice") to Ambac not more than ten nor less than five days
                         prior to the Demand Redemption Date.

                               Each bond of 2001 Series AP shall be redeemed by the
                         Company on the Demand Redemption Date therefore upon
                         surrender thereof by Ambac to the Trustee at a redemption
                         price equal to the principal amount thereof plus accrued
                         interest calculated as provided in Section 1 hereof from the
                         date of such payment to the Demand Redemption Date plus an
                         amount equal to the aggregate premium, if any, due and
                         payable on such Demand Redemption Date on a corresponding
                         amount of Series 1992-CC Bonds; provided, however, that in
                         the event of a receipt by the Trustee of a notice that Ambac
                         has terminated proceedings to enforce any right it may have
                         against the Company under the Series 1992-CC Insurance
                         Policy and the Bonds or both, then any Payment Demand shall
                         thereby be rescinded by Ambac, and no Demand Redemption
                         Notice shall be given, or, if already given, shall be
                         automatically annulled; but no such rescission or annulment
                         shall extend to or affect any subsequent default or impair
                         any right consequent thereon.

                               Anything herein contained to the contrary
                         notwithstanding, the Trustee is not authorized to take any
                         action pursuant to a Payment Demand and such Payment Demand
                         shall be of no force or effect, unless it is executed in the
                         name of Ambac by its President or one of its Managing
                         Directors or Vice Presidents.

                  Section 203. Amount and Denominations; DTC. The aggregate
principal amount of Notes that may be issued under this First Supplemental
Indenture is limited to $100,000,000.

         The Notes shall be issuable only in fully registered form and will

depositary ("DTC"), or its nominee who is hereby designated as "U.S. Depositary"
under the Original Indenture. The authorized denominations of Notes shall be
$100,000 and integral multiples of $1,000 in excess thereof.

                  Section 204. Interest, Interest Rates and Interest Rate Modes.
The Notes will initially bear interest at the Initial Interest Rate as set forth
on Annex A thereof for the Initial Interest Rate Period. Thereafter, each Note
at the option of the Company will bear interest in the Commercial Paper Term
Mode, the Long Term Rate Mode or the SPURS Mode. Each Note may bear interest for
designated Interest Rate Periods in the same or a different Interest Rate Mode
from other Notes. The interest rate for the Notes will be established
periodically as described herein by the applicable Remarketing Agent.

         Interest will be payable on any Note at Maturity and (i) in the Initial
Interest Rate Period, on the date or dates set forth on Annex A thereto; (ii)
for any Interest Rate Period in the Commercial Paper Term Mode, on the Interest
Rate Adjustment Date commencing the next succeeding Interest Rate Period for
such Note and on such other dates (if any) as will be established upon
conversion of such Note to the Commercial Paper Term Mode or upon remarketing of
the Note in a new Interest Rate Period in the Commercial Paper Term Mode and set
forth in the applicable Note; and (iii) in the Long Term Rate Mode or SPURS
Mode, no less frequently than semiannually on such dates as will be established
upon conversion of such Note to the Long Term Rate Mode or the SPURS Mode (or
upon remarketing of the Note in a new Interest Rate Period in the Long Term Rate
Mode or the SPURS Mode, as the case may be) and set forth in the applicable Note
in the case of a fixed interest rate, or as described below under "Floating
Interest Rates" in the case of a floating interest rate, and on the Interest
Rate Adjustment Date commencing the next succeeding Interest Rate Period. Such
interest will be payable to the Holder thereof as of the related Record Date,
which, for any Note (x) in the Initial Interest Rate Period, is the date or
dates set for therein; (y) in the Commercial Paper Term Mode, is the Business
Day prior to the related Interest Payment Date; and (z) bearing interest in the
Long Term Rate Mode or the SPURS Mode, is 15 days prior to the related Interest
Payment Date. Except as provided below under "Floating Interest Rates," if any
Interest Payment Date would otherwise be a day that is not a Business Day, such
Interest Payment Date will be postponed to the next succeeding Business Day, and
no interest will accrue on such payment for the period from and after such
Interest Payment Date to the date of such payment on the next succeeding
Business Day. Interest on Notes bearing interest in the Commercial Paper Term

                                       8
<PAGE>   10

Mode or at a floating interest rate during an Interest Rate Period in the Long
Term Rate Mode or the SPURS Mode will be computed on the basis of actual days
elapsed over 360; provided that, if an applicable Interest Rate Basis is the CMT
Rate or Treasury Rate (each as defined below), interest will be computed on the
basis of actual days elapsed over the actual number of days in the year.
Interest on Notes bearing interest at a fixed rate in the Long Term Rate Mode or
SPURS Mode will be computed on the basis of a year of 360 days consisting of
twelve 30-day months. Interest on Notes at the Initial Interest Rate will be
computed on the basis of a year of 360 days consisting of twelve 30-day months.

                  Determination of Interest Rates.

         General. The interest rate and, in the case of a floating interest
rate, the Spread (if any) and the Spread Multiplier (if any) for any Note will
be established by the applicable Remarketing Agent in a remarketing as described
in Section 207 hereof or otherwise not later than each Interest Rate Adjustment
Date for such Note as the minimum rate of interest and, in the case of a
floating interest rate, Spread (if any) and Spread Multiplier (if any) necessary
in the judgment of such Remarketing Agent to produce a par bid in the secondary
market for such Note on the date the interest rate is established. Such rate
will be effective for the next succeeding Interest Rate Period for such Note
commencing on such Interest Rate Adjustment Date.

         In the event that (i) the applicable Remarketing Agent has been removed
or has resigned and no successor has been appointed, or (ii) such Remarketing
Agent has failed to announce the appropriate interest rate, Spread, if any, or
Spread Multiplier, if any, as the case may be, on the Interest Rate Adjustment
Date for any Note for whatever reason, or (iii) the appropriate interest rate,
Spread, if any, or Spread Multiplier, if any, as the case may be, or Interest
Rate Period cannot be determined for any Note for whatever reason, then such
Note shall be automatically converted to the Commercial Paper Term Mode with a
Weekly Rate Period, determined as provided below under "Interest Rate Modes -
Commercial Paper Term Period", and the rate of interest thereon shall be equal
to the Special Interest Rate.

         The Trustee shall, upon request of any Beneficial Owner of a Note,
advise such Beneficial Owner or the applicable Remarketing Agent of the interest
rate and, in the case of a floating interest rate, the Interest Rate Basis or
Bases, Spread (if any) and Spread Multiplier (if any), and in each case the
other terms applicable to such Beneficial Owner's Notes for the next Interest
Rate Period. Neither the Trustee nor the Company will otherwise be required to
advise Beneficial Owners of the applicable interest rate. The interest rate and
other terms announced by the Remarketing Agent, absent manifest error, will be
binding and conclusive upon the Beneficial Owners, the Company and the Trustee.

                  Floating Interest Rates.

         While any Note bears interest in the Long Term Rate Mode or the SPURS
Mode (with respect to the period from, and including, the Interest Rate
Adjustment Date commencing such period to, but excluding, the SPURS Remarketing
Date), the Company may elect a floating interest rate by providing notice, which
will be in or promptly confirmed in writing (which

                                       9
<PAGE>   11

includes facsimile or appropriate electronic media), received by the Trustee and
the Remarketing Agent for such Note (the "Floating Interest Rate Notice") not
less than ten (10) days prior to the Interest Rate Adjustment Date for such Long
Term Rate Period or SPURS Rate Period. The Floating Interest Rate Notice must
identify by CUSIP number or otherwise the portion of the Note to which it
relates and state the Interest Rate Period (or portion thereof, in the case of
the SPURS Mode) therefor to which it relates. Each Floating Interest Rate Notice
must also state the Interest Rate Basis or Bases, the Initial Interest Reset
Date, the Interest Reset Period and Dates, the Interest Payment Period and
Dates, the Index Maturity and the Floating Rate Maximum Interest Rate and/or
Floating Rate Minimum Interest Rate, if any. If one or more of the applicable
Interest Rate Bases is LIBOR or the CMT Rate, the Floating Interest Rate Notice
shall also specify the Index Currency and Designated LIBOR Page or the
Designated CMT Maturity Index and Designated CMT Telerate Page, respectively.

         If any Note bears interest at a floating rate in a Long Term Rate
Period or SPURS Rate Period, such Note shall bear interest at the rate
determined by reference to the applicable Interest Rate Basis or Bases (a) plus
or minus the Spread, if any, and/or (b) multiplied by the Spread Multiplier, if
any, specified by the Remarketing Agent, in the case of a Long Term Rate Period,
or the SPURS Agent, in the case of a SPURS Rate Period, and recorded in Annex A
to such Note. Commencing on the Interest Rate Adjustment Date for such Interest
Rate Period, the rate at which interest on such Note shall be payable shall be
reset as of each Interest Reset Date during such Interest Rate Period specified
in the applicable Floating Interest Rate Notice.

         The applicable floating interest rate on any Note during any Interest
Rate Period will be determined by reference to the applicable Interest Rate
Basis or Interest Rate Bases, which may include (i) the CD Rate, (ii) the CMT
Rate, (iii) the Federal Funds Rate, (iv) LIBOR, (v) the Prime Rate, (vi) the
Treasury Rate, or (vii) such other Interest Rate Basis or interest rate formula
as may be specified in the applicable Floating Interest Rate Notice (each, an
"Interest Rate Basis").

         Unless otherwise specified in the applicable Floating Interest Rate
Notice, the interest rate with respect to each Interest Rate Basis will be
determined in accordance with the applicable provisions below. Except as set
forth above or specified in the applicable Floating Interest Rate Notice, the
interest rate in effect on each day shall be (i) if such day is an Interest
Reset Date, the interest rate determined as of the Interest Determination Date
immediately preceding such Interest Reset Date or (ii) if such day is not an
Interest Reset Date, the interest rate determined as of the Interest
Determination Date immediately preceding the most recent Interest Reset Date. If
any Interest Reset Date would otherwise be a day that is not a Business Day,
such Interest Reset Date shall be postponed to the next succeeding Business Day,
except that if LIBOR is an applicable Interest Rate Basis and such Business Day
falls in the next succeeding calendar month, such Interest Reset Date shall be
the immediately preceding Business Day. In addition, if the Treasury Rate is an
applicable Interest Rate Basis and the Interest Determination Date would
otherwise fall on an Interest Reset Date, then such Interest Reset Date will be
postponed to the next succeeding Business Day.

                                       10
<PAGE>   12

         The applicable Floating Interest Rate Notice will specify whether the
rate of interest will be reset daily, weekly, monthly, quarterly, semiannually
or annually or on such other specified basis (each, an "Interest Reset Period")
and the dates on which such rate of interest will be reset (each, an "Interest
Reset Date"). Unless otherwise specified in the applicable Floating Interest
Rate Notice, the Interest Reset Dates will be, in the case of a floating
interest rate which resets: (i) daily, each Business Day; (ii) weekly, the
Wednesday of each week (unless the Treasury Rate is an applicable Interest Rate
Basis, in which case the Tuesday of each week except as described below); (iii)
monthly, the third Wednesday of each month; (iv) quarterly, the third Wednesday
of March, June, September and December of each year, (v) semiannually, the third
Wednesday of the two months specified in the applicable Floating Interest Rate
Notice; and (vi) annually, the third Wednesday of the month specified in the
applicable Floating Interest Rate Notice.

         The interest rate applicable to each Interest Reset Period commencing
on the related Interest Reset Date will be determined as of the applicable
Interest Determination Date. The "Interest Determination Date" with respect to
the Federal Funds Rate and the Prime Rate will be the Business Day immediately
preceding the applicable Interest Reset Date; the "Interest Determination Date"
with respect to the CD Rate and the CMT Rate will be the second Business Day
immediately preceding the applicable Interest Reset Date; and the "Interest
Determination Date" with respect to LIBOR shall be the second London Business
Day immediately preceding the applicable Interest Reset Date, unless the Index
Currency is British pounds sterling, in which case the "Interest Determination
Date" will be the applicable Interest Reset Date. The "Interest Determination
Date" with respect to the Treasury Rate shall be the day in the week in which
the applicable Interest Reset Date falls on which day Treasury Bills (as defined
below) are normally auctioned (Treasury Bills are normally sold at an auction
held on Monday of each week, unless such Monday is a legal holiday, in which
case the auction is normally held on the immediately succeeding Tuesday,
although such auction may be held on the preceding Friday); provided, however,
that if an auction is held on the Friday of the week preceding the applicable
Interest Reset Date, the "Interest Determination Date" shall be such preceding
Friday; provided, further, that if the Interest Determination Date would
otherwise fall on an Interest Reset Date, then such Interest Reset Date will be
postponed to the next succeeding Business Day. The "Interest Determination Date"
pertaining to any Note, the interest rate of which is determined with reference
to two or more Interest Rate Bases specified in the applicable Floating Interest
Rate Notice, shall be the most recent Business Day which is at least two
Business Days prior to the applicable Interest Reset Date on which each Interest
Rate Basis is determinable. Each Interest Rate Basis shall be determined as of
such date, and the applicable interest rate shall take effect on the applicable
Interest Reset Date.

         Either or both of the following may also apply to the floating interest
rate on any Note for an Interest Rate Period: (i) a floating rate maximum
interest rate, or ceiling, that may accrue during any Interest Reset Period (the
"Floating Rate Maximum Interest Rate") and (ii) a floating rate minimum interest
rate, or floor, that may accrue during any Interest Reset Period (the "Floating
Rate Minimum Interest Rate"). In addition to any Floating Rate Maximum Interest
Rate that may apply, the interest rate on any Note will in no event be higher
that the maximum

                                       11
<PAGE>   13

rate permitted by New York law, as the same may be modified by United States
laws of general application.

         Except as provided below or in the applicable Floating Interest Rate
Notice, interest will be payable, in the case of floating interest rates which
reset: (i) daily, weekly or monthly, on the third Wednesday of each month or on
the third Wednesday of March, June, September and December of each year, as
specified in the applicable Floating Interest Rate Notice; (ii) quarterly, on
the third Wednesday of March, June, September and December of each year; (iii)
semiannually, on the third Wednesday of the two months of each year specified in
the applicable Floating Interest Rate Notice; and (iv) annually, on the third
Wednesday of the month of each year specified in the applicable Floating
Interest Rate Notice and, in each case, on the Business Day immediately
following the applicable Long Term Rate Period or SPURS Rate Period, as the case
may be. If any Interest Payment Date for the payment of interest at a floating
rate (other than following the end of the applicable Long Term Rate Period or
SPURS Rate Period, as the case may be) would otherwise be a day that is not a
Business Day, such Interest Payment Date will be postponed to the next
succeeding Business Day, except that if LIBOR is an applicable Interest Rate
Basis and such Business Day falls in the next succeeding calendar month, such
Interest Payment Date will be the immediately preceding Business Day.

         All percentages resulting from any calculation of floating interest
rates will be rounded to the nearest one hundred-thousandth of a percentage
point, with five one-millionths of a percentage point rounded upwards (e.g.,
9.876545% (or .09876545) would be rounded to 9.87655% (or .0987655)), and all
amounts used in or resulting from such calculation will be rounded, in the case
of United States dollars, to the nearest cent or, in the case of a foreign
currency or composite currency, to the nearest unit (with one-half cent or unit
being rounded upwards).

         Accrued floating rate interest will be calculated by multiplying the
principal amount of the applicable Note by an accrued interest factor. Such
accrued interest factor will be computed by adding the interest factor
calculated for each day in the applicable Interest Reset Period. Unless
otherwise specified in the applicable Floating Interest Rate Notice, the
interest factor for each such day will be computed by dividing the interest rate
applicable to such day by 360, if an applicable Interest Rate Basis is the CD
Rate, the Federal Funds Rate, LIBOR or the Prime Rate, or by the actual number
of days in the year if an applicable Interest Rate Basis is the CMT Rate or the
Treasury Rate. Unless otherwise specified in the applicable Floating Interest
Rate Notice, if the floating interest rate is calculated with reference to two
or more Interest Rate Bases, the interest factor will be calculated in each
period in the same manner as if only one of the applicable Interest Rate Bases
applied as specified in the applicable Floating Interest Rate Notice.

         Unless otherwise specified in the applicable Floating Interest Rate
Notice, The Bank of New York will be the "Calculation Agent." For any Remarketed
Note bearing interest at a floating rate, the applicable Remarketing Agent will
determine the interest rate in effect from the Interest Rate Adjustment Date for
such Remarketed Note to the Initial Interest Reset Date. The

                                       12
<PAGE>   14

Calculation Agent will determine the interest rate in effect for each Interest
Reset Period thereafter. Upon request of the Beneficial Owner of a Note, after
any Interest Rate Adjustment Date, the Calculation Agent or the Remarketing
Agent shall disclose the interest rate and, in the case of a floating interest
rate, Interest Rate Basis or Bases, Spread (if any) and Spread Multiplier (if
any), and in each case the other terms applicable to such Note then in effect
and, if determined, the interest rate that will become effective as a result of
a determination made for the next succeeding Interest Reset Date with respect to
such Note. Except as described herein with respect to a Note earning interest at
floating rates, no notice of the applicable interest rate, Spread (if any) or
Spread Multiplier (if any) shall be sent to the Beneficial Owner of any Note.

         Unless otherwise specified in the applicable Floating Interest Rate
Notice, the "Calculation Date", if applicable, pertaining to any Interest
Determination Date will be the earlier of (i) the tenth calendar day after such
Interest Determination Date or, if such day is not a Business Day, the next
succeeding Business Day or (ii) the Business Day immediately preceding the
applicable Interest Payment Date or Maturity, as the case may be.

         CD Rate. If an Interest Rate Basis for any Note is specified in the
applicable Floating Interest Rate Notice as the CD Rate, the CD Rate shall be
determined as of the applicable Interest Determination Date (a "CD Rate Interest
Determination Date") as the rate on such date for negotiable United States
dollar certificates of deposit having the Index Maturity specified in the
applicable Floating Interest Rate Notice as published in H.15(519) (as defined
below) under the heading "CDs (secondary market)", or, if not so published by
3:00 P.M., New York City time, on the related Calculation Date, the rate on such
CD Rate Interest Determination Date for negotiable United States dollar
certificates of deposit of the Index Maturity as published in H.15 Update (as
defined herein), or such other recognized electronic source used for the purpose
of displaying such rate, under the caption "CDs (secondary market)." If such
rate is not yet published in either H.15(519), H.15 Daily Update or another
recognized electronic source by 3:00 P.M., New York City time, on the related
Calculation Date, then the CD Rate on such CD Rate Interest Determination Date
will be calculated by the Calculation Agent and will be the arithmetic mean of
the secondary market offered rates as of 10:00 A.M., New York City time, on such
CD Rate Interest Determination Date, of three leading nonbank dealers in
negotiable United States dollar certificates of deposit in The City of New York
(which may include the Remarketing Agent or its affiliates) selected by the
Calculation Agent, after consultation with the Company, for negotiable United
States dollar certificates of deposit of major United States money center banks
for negotiable United States dollar certificates of deposit with a remaining
maturity closest to the Index Maturity in an amount that is representative for a
single transaction in that market at that time; provided, however, that if the
dealers so selected by the Calculation Agent are not quoting as mentioned in
this sentence, the CD Rate determined as of such CD Rate Interest Determination
Date will be the CD Rate in effect on such CD Rate Interest Determination Date.

         "H.15(519)" means the weekly statistical release designated as such, or
any successor publication, published by the Board of Governors of the Federal
Reserve System.

         CMT Rate. If an Interest Rate Basis for any Note is specified in the
applicable Floating Interest Rate Notice as the CMT Rate, the CMT Rate shall be
determined as of the applicable Interest Determination Date (a "CMT Rate
Interest Determination Date") as the rate displayed on the Designated CMT
Telerate Page (as defined below) under the caption "...Treasury Constant
Maturities...Federal Reserve Board Release H.15...Mondays Approximately 3:45
P.M.", under the column for the Designated CMT Maturity Index (as defined below)
for (i) if the Designated CMT Telerate Page is 7051, such CMT Rate Interest
Determination Date and (ii) if the Designated CMT Telerate Page is 7052, the
weekly or monthly average, as specified in the applicable Floating Interest Rate
Notice, for the week or the month, as applicable, ended immediately preceding
the week or the month, as applicable, in which the related CMT Rate Interest
Determination Date falls. If such rate is no longer displayed on the relevant
page or is not so displayed by 3:00 P.M., New York City time, on the related
Calculation Date, then the CMT Rate for such CMT Rate Interest Determination
Date will be such treasury constant maturity rate for the Designated CMT
Maturity Index as published in H.15(519). If such rate is no longer published or
is not published by 3:00 P.M., New York City time, on the related Calculation
Date, then the CMT Rate on such CMT Rate Interest Determination Date will be
such treasury constant maturity rate for the Designated CMT Maturity Index (or
other United States Treasury rate for the Designated CMT Maturity Index) for the
CMT Rate Interest Determination Date with respect to such Interest Reset Date as
may then be published by either the Board of Governors of the Federal Reserve
System or the United States Department of the Treasury that the Calculation
Agent determines to be comparable to the rate formerly displayed on the
Designated CMT Telerate Page and published in H.15(519). If such information is
not provided by 3:00 P.M., New York City time, on the related Calculation Date,
then the CMT Rate on the CMT Rate Interest Determination Date will be calculated
by the Calculation Agent and will be a yield to maturity, based on the
arithmetic mean of the secondary market bid prices as of approximately 3:30
P.M., New York City time, on such CMT Rate Interest Determination Date reported,
according to their written records, by three leading primary United States
government securities dealers in The City of New York (which may include the
Remarketing Agent or its affiliates) (each, a "Reference Dealer") selected by
the Calculation Agent, after consultation with the Company, (from five such
Reference Dealers selected by the Calculation Agent, after consultation with the
Company, and eliminating the highest quotation (or, in the event of equality,
one of the highest) and the lowest quotation (or, in the event of equality, one
of the lowest)), for the most recently issued direct noncallable fixed rate
obligations of the United States ("Treasury Notes") with an original maturity of
approximately the Designated CMT Maturity Index and a remaining term to maturity
of not less than such Designated CMT Maturity Index minus one year. If the
Calculation Agent is unable to obtain three such Treasury Note quotations, the
CMT Rate on such CMT Rate Interest Determination Date will be calculated by the
Calculation Agent and will be a yield to maturity based on the arithmetic mean
of the secondary market bid prices as of approximately 3:30 P.M., New York City
time, on such CMT Rate Interest Determination Date of three Reference Dealers in
The City of New York (from five

                                       14
<PAGE>   16
such Reference Dealers selected by the Calculation Agent, after consultation
with the Company, and eliminating the highest quotation (or, in the event of
equality, one of the highest) and the lowest quotation (or, in the event of
equality, one of the lowest)), for Treasury Notes with an original maturity of
the number of years that is the next highest to the Designated CMT Maturity
Index and a remaining term to maturity closest to the Designated CMT Maturity
Index and in an amount of at least U.S.$100 million. If three or four (and not
five) of such Reference Dealers are quoting as described above, then the CMT
Rate will be based on the arithmetic mean of the bid prices obtained and neither
the highest nor the lowest of such quotes will be eliminated; provided, however,
that if fewer than three Reference Dealers so selected by the Calculation Agent,
after consultation with the Company, are quoting as mentioned herein, the CMT
Rate determined as of such CMT Rate Interest Determination Date will be the CMT
Rate in effect on such CMT Rate Interest Determination Date. If two Treasury
Notes with an original maturity as described in the second preceding sentence
have remaining terms to maturity equally close to the Designated CMT Maturity
Index, the Calculation Agent will obtain quotations for the Treasury Note with
the shorter remaining term to maturity.

         "Designated CMT Maturity Index" means the original period to maturity
of the U.S. Treasury securities (either 1, 2, 3, 5, 7, 10, 20 or 30 years)
specified in the applicable Floating Interest Rate Notice with respect to which
the CMT Rate will be calculated or, if no such maturity is specified in the
applicable Floating Interest Rate Notice, 2 years.

         "Designated CMT Telerate Page" means the display on the Bridge
Telerate, Inc. (or any successor service) on the page specified in the
applicable Floating Interest Rate Notice (or any other page as may replace such
page on such service for the purpose of displaying Treasury Constant Maturities
as reported in H.15(519) or, if no such page is specified in the applicable
Floating Interest Rate Notice, page 7052.

         Federal Funds Rate. If an Interest Rate Basis for any Note is specified
in the applicable Floating Interest Rate Notice as the Federal Funds Rate, the
Federal Funds Rate shall be determined as of the applicable Interest
Determination Date (a "Federal Funds Rate Interest Determination Date"), the
rate on such date for United States dollar federal funds as published in
H.15(519) under the heading "Federal Funds (Effective)", as such rate is
displayed on Bridge Telerate, Inc. or any successor service on page 120 (or any
other page as may replace such page on such service) ("Telerate Page 120"), or,
if such rate does not appear on Telerate Page 120 or is not so published by 3:00
P.M., New York City time, on the related Calculation Date, the rate on such
Federal Funds Rate Interest Determination Date for United States dollar federal
funds as published in H.15 Daily Update, or such other recognized electronic
source used for the purpose of displaying such rate, under the caption "Federal
Funds (Effective)." If such rate does not appear on Telerate Page 120 or is not
yet published in H.15(519), H.15 Daily Update or another recognized electronic
source by 3:00 P.M., New York City time, on the related Calculation Date, then
the Federal Funds Rate on such Federal Funds Rate Interest Determination Date
will be calculated by the Calculation Agent and will be the arithmetic mean of
the rates for the last transaction in overnight United States dollar federal
funds arranged by three leading brokers of United States dollar federal funds
transactions in The City of New York (which may include the

                                       15
<PAGE>   17

Remarketing Agent or its affiliates) selected by the Calculation Agent, after
consultation with the Company, prior to 9:00 A.M., New York City time, on such
Federal Funds Rate Interest Determination Date; provided, however, that if the
brokers so selected by the Calculation Agent are not quoting as mentioned in
this sentence, the Federal Funds Rate determined as of such Federal Funds Rate
Interest Determination Date will be the Federal Funds Rate in effect on such
Federal Funds Rate Interest Determination Date.

         LIBOR. If an Interest Rate Basis for any Note is specified in the
applicable Floating Interest Rate Notice as LIBOR, LIBOR shall be determined by
the Calculation Agent as of the applicable Interest Determination Date (a "LIBOR
Interest Determination Date") in accordance with the following provisions:

                  (i)  With respect to any Interest Determination Date relating
to a Floating Rate Note for which the interest rate is determined with reference
to LIBOR (a "LIBOR Interest Determination Date"), LIBOR will be either: (a) if
"LIBOR Telerate" is specified in the applicable Floating Interest Rate Notice or
if neither "LIBOR Reuters" nor "LIBOR Telerate" is specified in the applicable
Floating Interest Rate Notice as the method for calculating LIBOR, the rate for
deposits in the Index Currency having the Index Maturity specified in the
applicable Floating Interest Rate Notice, commencing on such Interest Reset
Date, that appears on the Designated LIBOR Page as of 11:00 A.M., London time,
on such LIBOR Interest Determination Date; or (b) if "LIBOR Reuters" is
specified in the applicable Floating Interest Rate Notice, the arithmetic mean
of the offered rates (unless the Designated LIBOR Page by its terms provides
only for a single rate, in which case such single rate shall be used) for
deposits in the Index Currency having the Index Maturity specified in the
applicable Floating Interest Rate Notice, commencing on the applicable Interest
Reset Date, that appear (or, if only a single rate is required as aforesaid,
appears) on the Designated LIBOR Page as of 11:00 A.M., London time, on such
LIBOR Interest Determination Date. If fewer than two such offered rates so
appear, or if no such rate so appears, as applicable, LIBOR on such LIBOR
Interest Determination Date will be determined in accordance with the provisions
described in clause (ii) below.

                  (ii) With respect to a LIBOR Interest Determination Date on
which fewer than two offered rates appear, or no rate appears, as the case may
be, on the Designated LIBOR Page as specified in clause (i) above, the
Calculation Agent will request the principal London offices of each of four
major reference banks (which may include affiliates of the Remarketing Agent) in
the London interbank market, as selected by the Calculation Agent, after
consultation with the Company, to provide the Calculation Agent with its offered
quotation for deposits in the Index Currency for the period of the Index
Maturity specified in the applicable Floating Interest Rate Notice, commencing
on the applicable Interest Reset Date, to prime banks in the London interbank
market at approximately 11:00 A.M., London time, on such LIBOR Interest
Determination Date and in a principal amount that is representative for a single
transaction in the Index Currency in such market at such time. If at least two
such quotations are so provided, then LIBOR on such LIBOR Interest Determination
Date will be the arithmetic mean of such quotations. If fewer than two such
quotations are so provided, then LIBOR on such LIBOR Interest Determination Date
will be the arithmetic mean of the rates quoted at approximately

                                       16
<PAGE>   18

11:00 A.M., in the applicable Principal Financial Center, on such LIBOR Interest
Determination Date by three major banks (which may include affiliates of the
Remarketing Agent) in such Principal Financial Center selected by the
Calculation Agent, after consultation with the Company, for loans in the Index
Currency to leading European banks, having the Index Maturity specified in the
applicable Floating Interest Rate Notice and in a principal amount that is
representative for a single transaction in the Index Currency in such market at
such time; provided, however, that if the banks so selected by the Calculation
Agent are not quoting as mentioned in this sentence, LIBOR determined as of such
LIBOR Interest Determination Date will be LIBOR in effect on such LIBOR Interest
Determination Date.

         "Index Currency" means the currency specified in the applicable
Floating Interest Rate Notice as to which LIBOR shall be calculated or, if no
such currency is specified in the applicable Floating Interest Rate Notice,
United States dollars.

         "Designated LIBOR Page" means (a) if "LIBOR Reuters" is specified in
the applicable Floating Interest Rate Notice, the display on the Reuter Monitor
Money Rates Service (or any successor service) on the page specified in the
applicable Floating Interest Rate Notice (or any other page as may replace such
page on such service) for the purpose of displaying the London interbank rates
of major banks for the Index Currency, or (b) if "LIBOR Telerate" is specified
in the applicable Floating Interest Rate Notice or neither "LIBOR Reuters" nor
"LIBOR Telerate" is specified in the applicable Floating Interest Rate Notice as
the method for calculating LIBOR, the display on Bridge Telerate, Inc. (or any
successor service) on the page specified in the applicable Floating Interest
Rate Notice (or any other page as may replace such page on such service) for the
purpose of displaying the London interbank rates of major banks for the Index
Currency.

         Prime Rate. If an Interest Rate Basis for any Note is specified on the
face hereto as the Prime Rate, the Prime Rate shall be determined as of the
applicable Interest Determination Date (a "Prime Rate Interest Determination
Date") as the rate on such date as such rate is published in H.15(519) under the
caption "Bank Prime Loan" or, if not published by 3:00 P.M., New York City time,
on the related Calculation Date, the rate on such Prime Rate Interest
Determination Date as published in H.15 Daily Update, or such other recognized
electronic source used for the purpose of displaying such rate under the caption
"Bank Prime Loan." If such rate is not yet published in H.15(519), H.15 Daily
Update or another recognized electronic source by 3:00 P.M., New York City time,
on the related Calculation Date, then the Prime Rate shall be the arithmetic
mean of the rates of interest publicly announced by each bank that appears on
the Reuters Screen US PRIME1 Page (as defined below) as such bank's prime rate
or base lending rate as of 11:00 A.M. New York City time, on such Prime Rate
Interest Determination Date. If fewer than four such rates so appear on the
Reuters Screen US PRIME1 Page for such Prime Rate Interest Determination Date,
then the Prime Rate shall be the arithmetic mean of the prime rates or base
lending rates quoted on the basis of the actual number of days in the year
divided by a 360-day year as of the close of business on such Prime Rate
Interest Determination Date by three major banks (which may include The Bank of
New York or affiliates of the Remarketing Agent) in The City of New York
selected by the Calculation Agent, after consultation with the

                                       17
<PAGE>   19

Company; provided, however, that if the banks or trust companies so selected by
the Calculation Agent are not quoting as mentioned in this sentence, the Prime
Rate determined as of such Prime Rate Interest Determination Date will be the
Prime Rate in effect on such Prime Rate Interest Determination Date.

         "Reuters Screen US PRIME1 Page" means the display on the Reuter Monitor
Money Rates Service (or any successor service) on the "US PRIME1" page (or such
other page as may replace the US PRIME1 page on such service) for the purpose of
displaying prime rates or base lending rates of major United States banks.

         Treasury Rate. If an Interest Rate Basis for any Note is specified in
the applicable Floating Interest Rate Notice as the Treasury Rate, the Treasury
Rate shall be determined as of the applicable Interest Determination Date (a
"Treasury Rate Interest Determination Date") as the rate from the auction held
on such Treasury Rate Interest Determination Date (the "Auction") of direct
obligations of the United States ("Treasury Bills") having the Index Maturity
specified in the applicable Floating Interest Rate Notice under the caption
"INVESTMENT RATE", on the display on Bridge Telerate, Inc. (or any successor
service) on page 56 (or any other page as may replace such page on such service)
("Telerate Page 56") or page 57 (or any other page as may replace such page on
such service) ("Telerate Page 57") or, if not so published by 3:00 P.M., New
York City time, on the related Calculation Date, the Bond Equivalent Yield (as
defined below) of the rate for such Treasury Bills as published in H.15 Daily
Update, or such other recognized electronic source used for the purpose of
displaying such rate, under the caption "U.S. Government Securities/Treasury
Bills/Auction High" or, if not so published by 3:00 P.M., New York City time, on
the related Calculation Date, the Bond Equivalent Yield of the auction rate of
such Treasury Bills as announced by the United States Department of the
Treasury. In the event that the auction rate of Treasury Bills having the Index
Maturity in the applicable Floating Interest Rate Notice is not so announced by
the United States Department of the Treasury, or if no such Auction is held,
then the Treasury Rate will be the Bond Equivalent Yield of the rate on such
Treasury Rate Interest Determination Date of Treasury Bills having the Index
Maturity specified in the applicable Floating Interest Rate Notice as published
in H.15(519) under the caption "U.S. Government Securities/Treasury
Bills/Secondary Market" or, if not yet published by 3:00 P.M., New York City
time, on the related Calculation Date, the rate on such Treasury Rate Interest
Determination Date of such Treasury Bills as published in H.15 Daily Update, or
such other recognized electronic source used for the purpose of displaying such
rate, under the caption "U.S. Government Securities/Treasury Bills/Secondary
Market." If such rate is not yet published in H.15(519), H.15 Daily Update or
another recognized electronic source, then the Treasury Rate will be calculated
by the Calculation Agent and will be the Bond Equivalent Yield of the arithmetic
mean of the secondary market bid rates, as of approximately 3:30 P.M., New York
City time, on such Treasury Rate Interest Determination Date, of three primary
United States government securities dealers (which may include the Remarketing
Agent or its affiliates) selected by the Calculation Agent, after consultation
with the Company, for the issue of Treasury Bills with a remaining maturity
closest to the Index Maturity specified in the applicable Floating Interest Rate
Notice; provided, however, that if the dealers so selected by the Calculation
Agent are not quoting as mentioned in this sentence, the Treasury Rate
determined as of such Treasury

                                       18
<PAGE>   20

Rate Interest Determination Date will be the Treasury Rate in effect on such
Treasury Rate Interest Determination Date.

         "Bond Equivalent Yield" means a yield (expressed as a percentage)
calculated in accordance with the following formula:

                  Bond Equivalent Yield =    D x N
                                            ------        X   100
                                          360 - (D x M)

                  where "D" refers to the applicable per annum rate for Treasury
Bills quoted on a bank discount basis, "N" refers to 365 or 366, as the case may
be, and "M" refers to the actual number of days in the applicable Interest Reset
Period.

                  Interest Rate Modes.

         Commercial Paper Term Mode. The Interest Rate Period for any Note in
the Commercial Paper Term Mode shall be a period of not less than one nor more
than 364 consecutive calendar days, as determined by the Company (as described
below in Section 205) or, if not so determined, by the Remarketing Agent for
such Note (in its best judgment in order to obtain the lowest interest cost for
such Note). Each Commercial Paper Term Period will commence on the Interest Rate
Adjustment Date therefor and end on the day preceding the date specified by such
Remarketing Agent as the first day of the next Interest Rate Period for such
Note. A "Weekly Rate Period" is a Commercial Paper Term Period and will be a
period of seven days commencing on any Interest Rate Adjustment Date and ending
on the day preceding the first day of the next Interest Rate Period for such
Note. The interest rate for any Commercial Paper Term Period relating to a Note
will be determined not later than 11:50 a.m., New York City time, on the
Interest Rate Adjustment Date for such Note (subject to Section 207), which is
the first day of each Interest Rate Period for such Note.

         Long Term Rate Mode. The Interest Rate Period for any Note in the Long
Term Rate Mode will be established by the Company (as described in Section 205
below) as a period of more than 364 days and not exceeding the remaining term to
the Stated Maturity of such Note; provided, however, that such Interest Rate
Period must end on the day prior to an Interest Payment Date for such Note; and
provided further that, if so provided in a Note in the Long Term Rate Mode and
specified at the time of remarketing into a Long Term Rate Period, the Company
may shorten the Interest Rate Period and provide for payment of a premium, if
any, in respect thereof for any such Note upon written notice to the Remarketing
Agent and the Trustee not less than thirty (30) days prior to the date upon
which such shortened Interest Rate Period shall expire. Promptly upon receipt of
such notice and, in any case, not later than the close of business on such date,
the Trustee will transmit such information to DTC in accordance with DTC's
procedures as in effect from time to time. In such case, the next Interest Rate
Adjustment Date otherwise set forth in such Note shall instead be the Business
Day immediately following the expiration of such Interest Rate Period. The
interest rate, or Spread (if any) and Spread Multiplier (if any) for any Note in
the Long Term Rate Mode will be determined not later than

                                       19
<PAGE>   21

11:50 a.m., New York City time, on the Interest Rate Adjustment Date for such
Notes (subject to Section 207), which is the first day of the Interest Rate
Period for such Note.

         If any Note is subject to early remarketing as provided above, the
Interest Rate Period may be shortened by the Company to end on any date on or
after the Initial Early Remarketing Date, if any, specified in the Note, upon
prior written notice as provided above. On or after the Initial Early
Remarketing Date, if any, on the Interest Rate Adjustment Date relating to such
shortened Interest Rate Period for such Note, the Company will pay a premium to
the tendering Beneficial Owner of the Note, together with accrued interest, if
any, thereon at the applicable rate payable to such Interest Rate Adjustment
Date. Unless otherwise specified in the Note, the premium shall be an amount
equal to the Initial Early Remarketing Premium specified therein (as adjusted by
the Annual Early Remarketing Premium Percentage Reduction specified therein, if
applicable), multiplied by the principal amount of the Note subject to early
remarketing. The Initial Early Remarketing Premium, if any, shall decline at
each anniversary of the Initial Early Remarketing Date by an amount equal to the
applicable Annual Early Remarketing Premium Percentage Reduction, if any,
specified in the Note until the premium is equal to 0.

         SPURS Mode. So long as any Notes are in the SPURS Mode, the provisions
set forth in Article Two applicable to the remarketing of Notes generally shall
apply to such Notes only to the extent expressly provided in Article Three.

         The Interest Rate Period for any Note in the SPURS Mode will be
established by the Company (as described in Section 205 below) as a period of
more than 364 days and not exceeding the remaining term to the Stated Maturity
of such Note; provided, however, that such Interest Rate Period must end on the
day prior to an Interest Payment Date for such Note. The SPURS Rate Period shall
consist of the period from and including the Interest Rate Adjustment Date
commencing such Interest Rate Period to and excluding the SPURS Remarketing Date
and the period from and including the SPURS Remarketing Date to, but excluding,
the next succeeding Interest Rate Adjustment Date, as described in Article Three
and subject to the conditions therein and otherwise herein described. The
interest rate and, in the case of a floating interest rate, the Spread, if any,
and the Spread Multiplier, if any, to the SPURS Remarketing Date for any Note in
the SPURS Mode will be determined not later than 11:50 a.m., New York City time,
on the Interest Rate Adjustment Date for such Note, which for the SPURS Mode is
the first day of the Interest Rate Period for such Note.

                  Section 205. Conversion. The Company may change the Interest
Rate Mode at its option in the manner described below.

                  (a) Conversion Between Commercial Paper Term Periods. Each
Note in a Commercial Paper Term Period may be remarketed into the same Interest
Rate Period or converted at the option of the Company to a different Commercial
Paper Term Period on any Interest Rate Adjustment Date for such Note upon
receipt by the applicable Remarketing Agent and the Trustee of a Conversion
Notice prior to 9:30 a.m., New York City time, or the remarketing of such Note,
whichever later occurs, on such Interest Rate Adjustment Date.

                                       20
<PAGE>   22

                  (b) Conversion from the Commercial Paper Term Mode to the Long
Term Rate Mode or the SPURS Mode. Each Note in the Commercial Paper Term may be
converted at the option of the Company to the Long Term Rate Mode or the SPURS
Mode on any Interest Rate Adjustment Date upon receipt not less than ten days
prior to such Interest Rate Adjustment Date by the applicable Remarketing Agent
and the Trustee of a Conversion Notice from the Company.

                  (c) Conversion Between Long Term Rate Periods or from the Long
Term Rate Mode or the SPURS Mode to the Commercial Paper Term Mode or the SPURS
Mode. Each Note in a Long Term Rate Period may be remarketed into the same
Interest Rate Period or converted at the option of the Company to a different
Long Term Rate Period or from the Long Term Rate Mode to the Commercial Paper
Term Mode or the SPURS Mode, or from the SPURS Mode to a different SPURS Mode or
to the Long Term Rate Mode or the Commercial Paper Term Mode, on any Interest
Rate Adjustment Date for such Note upon receipt by the Trustee and the
Remarketing Agent of a Conversion Notice from the Company not less than ten days
prior to such Interest Rate Adjustment Date.

                  (d) Conversion Notice. Each Conversion Notice must state each
Note to which it relates and the new Interest Rate Mode (if applicable), the new
Interest Rate Period, the Conversion Date and, with respect to any Long Term
Rate Period, any optional redemption or repayment terms for each such Note. If
the Company revokes a Conversion Notice or the Trustee and the Remarketing Agent
fail to receive a Conversion Notice from the Company by the specified date in
advance of the Interest Rate Adjustment Date for a Note, the Note shall be
converted automatically to a Weekly Rate Period.

                  (e) Revocation or Change of Conversion Notice or Floating
Interest Rate Notice. The Company may, upon written notice received by the
Trustee and the applicable Remarketing Agent, revoke any Conversion Notice or
Floating Interest Rate Notice or change the Interest Rate Mode to which such
Conversion Notice relates or change any Floating Interest Rate Notice up to 9:30
a.m., New York City time, on the Conversion Date, subject to the provisions of
subsection (f) below.

                  (f) Limitation on Conversion, Change of Conversion Notice or
Floating Interest Rate Notice and Revocation. Notwithstanding the foregoing
subsections (a), (b), (c), (d) and (e) the Company may not, without the consent
of the applicable Remarketing Agent, convert any Note or revoke or change any
Conversion Notice or Floating Interest Rate Notice at or after the time at which
such Remarketing Agent has determined the interest rate, or Spread (if any) and
Spread Multiplier (if any), for any Note being remarketed (i.e., the time at
which such Note has been successfully remarketed, subject to settlement on the
related Interest Rate Adjustment Date). The Remarketing Agent will advise the
Company of indicative rates from time to time, or at any time upon the request
of the Company, prior to making such determination of the interest rate, Spread
or Spread Multiplier, as the case may be.

                  Section 206. Mandatory Tender of Notes. Each Note will be
automatically tendered for purchase, or deemed tendered for purchase, on each
Interest Rate Adjustment Date relating thereto. Notes will be purchased on the
Interest Rate Adjustment Date relating thereto as described in Section 207.
hereof.

                  Section 207. Remarketing. The interest rate on each Note will
be established from time to time by each Remarketing Agent responsible for the
remarketing thereof in accordance with the following procedures:

                  (a) Interest Rate Adjustment Date; Determination of Interest
Rate. By 11:00 a.m., New York City time, on the Interest Rate Adjustment Date
for any Note, the applicable Remarketing Agent will determine the interest rate
for such Note being remarketed to the nearest one hundred-thousandth (0.00001)
of one percent per annum for the next Interest Rate Period in the case of a
fixed interest rate, and the Spread (if any) and Spread Multiplier (if any) in
the case of a floating interest rate; provided, that between 11:00 a.m., New
York City time, and 11:50 a.m., New York City time, the Remarketing Agent and
the Standby Remarketing Agent(s), if any, shall use their reasonable efforts to
determine the interest rate for any Notes not successfully remarketed as of the
applicable deadline specified in this paragraph. In determining the applicable
interest rate for such Note and other terms, such Remarketing Agent will, after
taking into account market conditions as reflected in the prevailing yields on
fixed and variable rate taxable debt securities, (i) consider the principal
amount of all Notes tendered or to be tendered on such date and the principal
amount of such Notes prospective purchasers are or may be willing to purchase
and (ii) contact, by telephone or otherwise, prospective purchasers and
ascertain the interest rates therefor at which they would be willing to hold or
purchase such Notes.

                  (b) Notification of Results; Settlement. By 12:30 p.m., New
York City time, on the Interest Rate Adjustment Date for any Notes, the
applicable Remarketing Agent will notify the Company and the Trustee in writing
(which may include facsimile or other electronic transmission), of (i) the
interest rate or, in the case of a floating interest rate, the initial interest
rate, the Spread and Spread Multiplier and the Initial Interest Reset Date,
applicable to such Notes for the next Interest Rate Period, (ii) the Interest
Rate Adjustment Date, (iii) the Interest Payment Dates, for any Notes in the
Commercial Paper Term Mode (if other than the Interest Rate Adjustment Date),
the Long Term Rate Mode or the SPURS Mode, (iv) the optional redemption terms,
if any, and early remarketing terms, if any, in the case of a remarketing into a
Long Term Rate Period, (v) the aggregate principal amount of tendered Notes and
(vi) the aggregate principal amount of such tendered Notes which such
Remarketing Agent was able to remarket, at a price equal to 100% of the
principal amount thereof plus accrued interest, if any. Immediately after
receiving such notice, and in any case, not later than 1:30 p.m. New York City
time, the Trustee will transmit such information and any other settlement
information required by DTC to DTC in accordance with DTC's procedures as in
effect from time to time.

         By telephone at approximately 1:00 p.m., New York City time, on such
Interest Rate Adjustment Date, the applicable Remarketing Agent will advise each
purchaser of such Notes (or

                                       22
<PAGE>   24

the DTC participant of each such purchaser who it is expected in turn will
advise such purchaser) of the principal amount of such Notes that such purchaser
is to purchase.

         Each purchaser of Notes in a remarketing will be required to give
instructions to its DTC participant to pay the purchase price therefor in same
day funds to the applicable Remarketing Agent against delivery of the principal
amount of such Notes by book-entry through DTC by 3:00 p.m., New York City time,
on the Interest Rate Adjustment Date.

         All tendered Notes will be automatically delivered to the account of
the Trustee (or such other account meeting the requirements of DTC's procedures
as in effect from time to time), by book-entry through DTC against payment of
the purchase price or redemption price therefor, on the Interest Rate Adjustment
Date relating thereto.

         The applicable Remarketing Agent will make, or cause the Trustee to
make, payment to the DTC participant of each tendering Beneficial Owner of Notes
subject to a remarketing, by book-entry through DTC by the close of business on
the Interest Rate Adjustment Date against delivery through DTC of such
Beneficial Owner's tendered Notes, of the purchase price for tendered Notes that
have been sold in the remarketing. If any such Notes were purchased pursuant to
a Special Mandatory Purchase, subject to receipt of funds from the Company or
the Liquidity Provider, if any, as the case may be, the Trustee will make such
payment of the purchase price of such Notes plus accrued interest, if any, to
such date.

         The transactions described above for a remarketing of any Notes will be
executed on the Interest Rate Adjustment Date for such Notes through DTC in
accordance with the procedures of DTC, and the accounts of the respective DTC
participants will be debited and credited and such Notes delivered by book-entry
as necessary to effect the purchases and sales thereof, in each case as
determined in the related remarketing.

         Except as otherwise set forth in Section 208 hereof, any Notes tendered
in a remarketing will be purchased solely out of the proceeds received from
purchasers of such Notes in such remarketing, and none of the Trustee, the
applicable Remarketing Agent, any Standby Remarketing Agent or the Company will
be obligated to provide funds to make payment upon any Beneficial Owner's tender
in a remarketing.

         Although tendered Notes will be subject to purchase by a Remarketing
Agent in a remarketing, such Remarketing Agent and any Standby Remarketing Agent
will not be obligated to purchase any such Notes.

         The settlement and remarketing procedures described above, including
provisions for payment by purchasers of tendered Notes or for payment to selling
Beneficial Owners of tendered Notes, may be modified to the extent required by
DTC. In addition, each Remarketing Agent may, without the consent of the Holders
of the Notes, modify the settlement and remarketing procedures set forth above
in order to facilitate the settlement and remarketing process.

                                       23
<PAGE>   25

         As long as DTC's nominee holds the certificates representing the Notes
in the book-entry system of DTC, no certificates for such Notes will be
delivered by any selling Beneficial Owner to reflect any transfer of Notes
effected in any remarketing.

         The Trustee shall confirm to DTC the interest rate for the following
Interest Rate Period in accordance with DTC's procedures as in effect from time
to time.

         The interest rate announced by the applicable Remarketing Agent, absent
manifest error, shall be binding and conclusive upon the Beneficial Owners, the
Company and the Trustee.

                  (c) Failed Remarketing. Notes not successfully remarketed will
be subject to Special Mandatory Purchase by the Company (a "Special Mandatory
Purchase"). The obligation of the Company to effect a Special Mandatory Purchase
of the Notes (the "Special Mandatory Purchase Right") can be satisfied either
directly by the Company or through a Liquidity Provider. By 12:00 o'clock noon,
New York City time, on any Interest Rate Adjustment Date, the applicable
Remarketing Agent will notify the Liquidity Provider, if any, the Trustee and
the Company by telephone or facsimile, confirmed in writing, of the principal
amount of Notes that such Remarketing Agent and the applicable Standby
Remarketing Agent, if any, were unable to remarket on such date. In the event
that the Company has entered into a Standby Note Purchase Agreement which is in
effect on such date, such notice will constitute a demand for the benefit of the
Company to the Liquidity Provider to purchase such unremarketed Notes at a price
equal to the outstanding principal amount thereof pursuant to the terms of such
Standby Note Purchase Agreement. If a Standby Note Purchase Agreement is not in
effect on such date, or if the Liquidity Provider fails to advance funds under
the Standby Note Purchase Agreement, the Company hereby agrees to purchase such
unremarketed Notes. In each case the Company will pay all accrued and unpaid
interest, if any, on unremarketed Notes to such Interest Rate Adjustment Date.
Payment of the principal amount of unremarketed Notes by the Company or the
Liquidity Provider, as the case may be, and payment of accrued and unpaid
interest, if any, by the Company, shall be made by deposit of same-day funds
with the Trustee (or such other account meeting the requirements of DTC's
procedures as in effect from time to time) irrevocably in trust for the benefit
of the Beneficial Owners of Notes subject to Special Mandatory Purchase by 3:00
p.m., New York City time, on such Interest Rate Adjustment Date.

                  Section 208. Purchase and Redemption of Notes.

                  (a) Special Mandatory Purchase. If by 12:00 o'clock noon, New
York City time, on any Interest Rate Adjustment Date for any Notes, the
applicable Remarketing Agent and the applicable Standby Remarketing Agent(s)
have not remarketed all such Notes, the Notes that are unremarketed are subject
to Special Mandatory Purchase. Either the Company or, subject to the terms and
conditions of a Standby Note Purchase Agreement, if any, which may be in effect
on such date, the Liquidity Provider (if any), will deposit same-day funds in
the account of the Trustee (or such other account meeting the requirements of
DTC's procedures as in effect from time to time) irrevocably in trust for the
benefit of the Beneficial Owners of Notes subject to Special Mandatory Purchase
by 3:00 p.m., New York City time, on such Interest Rate

                                       24
<PAGE>   26

Adjustment Date. Such funds shall be in an amount sufficient to pay the
aggregate purchase price of such unremarketed Notes, equal to 100% of the
principal amount thereof. In the event a Standby Note Purchase Agreement is in
effect but the Liquidity Provider shall fail to advance funds for whatever
reason thereunder, the Company hereby agrees to purchase such unremarketed Notes
on such Interest Rate Adjustment Date. The Company hereby agrees to pay the
accrued interest, if any, on such Notes by depositing sufficient same-day funds
therefor in the account of the Trustee (or such other account meeting the
requirements of DTC's procedures as in effect from time to time) by 3:00 p.m.,
New York City time, on such Interest Rate Adjustment Date.

                  Failure by the Company to purchase Notes pursuant to a Special
Mandatory Purchase in the manner provided in the Notes will constitute an Event
of Default under the Original Indenture in which event the date of such failure
shall constitute a date of Maturity for such Notes and the principal amount
thereof may be declared due and payable in the manner and with the effect
provided for in the Original Indenture. Following such failure to pay pursuant
to a Special Mandatory Purchase, such Notes will bear interest at the Special
Interest Rate as provided for in Section 204 hereof.

         If the Company enters into a Standby Note Purchase Agreement with a
Liquidity Provider, Notes purchased by the Liquidity Provider ("Purchased
Notes") shall bear interest at the rates and be payable on the dates as may be
agreed upon by the Company and the Liquidity Provider. Upon purchase of any Note
by the Liquidity Provider, all interest accruing thereon from the last date for
which interest was paid shall accrue for the benefit of and be payable to the
Liquidity Provider. Unless an event of default under the Standby Note Purchase
Agreement occurs, the applicable Remarketing Agent shall continue its
remarketing efforts with respect to Purchased Notes until the earlier to occur
of a successful remarketing of such Purchased Notes or the expiration of the
Standby Note Purchase Agreement. In the event the Liquidity Provider holds
Purchased Notes on the date the Standby Note Purchase Agreement expires, the
Company will be required to purchase such Notes on such date at a purchase price
equal to the principal amount thereof plus accrued interest thereon to the
purchase date. Such Notes will remain outstanding and enjoy the benefits of the
Original Indenture and this First Supplemental Indenture until such time as the
Company delivers the Notes to the Trustee for cancellation.

                  (b) Optional Redemption on any Interest Rate Adjustment Date.
Each Note is subject to redemption at the option of the Company in whole or in
part on any Interest Rate Adjustment Date, without notice to the Holders
thereof, at a redemption price equal to the aggregate principal amount of such
Notes to be redeemed plus accrued interest thereon to the redemption date.

                  (c) Redemption While Notes are in the Long Term Rate Mode. Any
Notes in the Long Term Rate Mode are subject to redemption at the option of the
Company at the times and upon the terms specified at the time of conversion to
or within such Long Term Rate Mode.

                                       25
<PAGE>   27

                  (d) Notice of Redemption. In the case of any Note being
redeemed on an Interest Rate Adjustment Date therefor, the Company shall give
the applicable Remarketing Agent and the Trustee written notice of such
redemption prior to the time the interest rate applicable to the next Interest
Rate Period for such Note is established by such Remarketing Agent. In any other
case, the Company shall give the Remarketing Agents and the Trustee written
notice of redemption of any Note at least two Business Days prior to the date
notice is required to be given to Holders. In addition, the Company shall give
each Remarketing Agent with respect to any Note being repaid at the option of
the Holder thereof and the Trustee notice as soon as practicable, and in any
event not later than twelve Business Days prior to the next succeeding Interest
Rate Adjustment Date therefor of each such Note which will be repaid by the
Company at the option of the Holder thereof on or prior to such Interest Rate
Adjustment Date. Each Remarketing Agent's obligation to remarket any Note shall
terminate immediately upon receipt by it from the Company of any notice of
redemption or repayment thereof.

                  (e) Allocation. Except in the case of a Special Mandatory
Purchase, if the Notes are to be redeemed in part, DTC, after receiving notice
of redemption specifying the aggregate principal amount of Notes to be so
redeemed, will determine by lot (or otherwise in accordance with the procedures
of DTC) the principal amount of such Notes to be redeemed from the account of
each DTC participant. After making its determination as described above, DTC
will give notice of such determination to each DTC participant from whose
account such Notes are to be redeemed. Each such DTC participant, upon receipt
of such notice, will in turn determine the principal amount of Notes to be
redeemed from the accounts of the Beneficial Owners of such Notes for which it
serves as DTC participant, and give notice of such determination to the
Remarketing Agent.

                  Section 209. Form and Other Terms of the Notes.

                  (a) Attached hereto as Exhibit A is the form of Note, which
form is hereby established as the form in which Notes may be issued bearing
interest at the Initial Interest Rate or in the Commercial Paper Term Mode, the
Long Term Rate Mode or the SPURS Mode. Annex A to Exhibit A is deemed to be a
part of such Note and such Annex may be changed upon the mutual agreement of the
Company and the Trustee to reflect changes occasioned by remarketings. The Notes
will initially bear legends indicating that they have not been registered under
the Securities Act of 1933, as amended, and restricting transfers thereof.

                  (b) Attached hereto as Exhibit B is a form of Liquidity
Provider Note, which form is hereby established as a form in which Notes held by
the Liquidity Provider may be issued. The form of Liquidity Provider Note may be
amended to reflect changes occasioned by remarketings upon the mutual agreement
of the Company and the Trustee, but only with the consent of the applicable
Administrative Agent.

                  (c) Subject to (a) and (b) above, any Note may be issued in
such other form as may be provided by, or not inconsistent with, the terms of
the Original Indenture and this First Supplemental Indenture.

                                 ARTICLE THREE

                                 THE SPURS MODE

                  Section 301. Applicability of Article. The provisions of this
Article Three shall apply to any Note in the SPURS Mode. To the extent that any
provision of this Article Three conflicts with any provision of Article Two, the
provisions set forth in this Article Three shall govern.

                  Section 302. Interest To Remarketing Date. Each Note in the
SPURS Mode shall bear interest at the annual interest rate established by the
SPURS Agent from, and including the Interest Rate Adjustment Date commencing the
Interest Rate Period for the SPURS Mode to, but excluding, the date (the "SPURS
Remarketing Date") designated at such time by the SPURS Agent after consultation
with the Company and set forth in Annex A to the applicable Note. Such interest
rate will be the minimum rate of interest and, in the case of a floating
interest rate, Spread (if any) and Spread Multiplier (if any) necessary in the
judgment of such SPURS Agent to produce a par bid in the secondary market for
such Note on the date the interest rate is established. The designated SPURS
Remarketing Date shall be an Interest Payment Date within such Interest Rate
Period.

                  Section 303. Tender; Remarketing. The SPURS Agent's
obligations set forth herein shall be performed pursuant to the SPURS
Remarketing Agreement.

                  (a) Mandatory Tender. Provided that the SPURS Agent gives
notice to the Company and the Trustee on a Business Day not later than ten (10)
days prior to the SPURS Remarketing Date of its intention to purchase the Notes
for remarketing (the "Notification Date"), each Note shall be automatically
tendered, or deemed tendered, to the SPURS Agent for remarketing on the SPURS
Remarketing Date, except in the circumstances set forth in Section 304. The
purchase price for the tendered Notes to be paid by the SPURS Agent shall equal
100% of the principal amount thereof. When the Notes are tendered for
remarketing, the SPURS Agent may remarket the Notes for its own account at
varying prices to be determined by the SPURS Agent at the time of each sale.
From, and including, the SPURS Remarketing Date to, but excluding, the next
succeeding Interest Rate Adjustment Date, the Notes shall bear interest at the
SPURS Interest Rate. If the SPURS Agent elects to remarket the Notes, the
obligation of the SPURS Agent to purchase the Notes on the SPURS Remarketing
Date is subject to, among other things, the conditions specified in the
applicable SPURS Remarketing Agreement. If the SPURS Agent for any reason does
not purchase all tendered Notes on the SPURS Remarketing Date or if the SPURS
Agent gives notice of its intention to remarket the Notes but for any reason
does not purchase all tendered Notes on the SPURS Remarketing Date, then as of
such date the Notes will cease to be in the SPURS Mode, the SPURS Remarketing
Date will constitute an Interest Rate Adjustment Date, and the Notes may be
subject to remarketing on such date by a Remarketing Agent appointed by the
Company in the Commercial Paper Mode or the Long Term Rate Mode or a new SPURS
Mode established by the Company in accordance with the procedures set forth in
Section 205 hereof, provided that, in such case, the notice period required for
conversion shall

                                       27
<PAGE>   29

be the lesser of ten (10) days and the period commencing the date that the SPURS
Agent notifies the Company that it will not purchase the Notes for remarketing
on the SPURS Remarketing Date or fails to so purchase, as the case may be.

                  (b) Remarketing. The SPURS Interest Rate shall be established
by the SPURS Agent in accordance with the following procedures:

                  (i) The SPURS Interest Rate. Subject to the SPURS Agent's
election to remarket the Notes as provided in subsection (a) above, the SPURS
Interest Rate shall be determined by the SPURS Agent by 3:30 p.m., New York City
time, on the third Business Day preceding the SPURS Remarketing Date (the
"Determination Date") to the nearest one hundred-thousandth (0.00001) of one
percent per annum, and shall be equal to the Base Rate established by the SPURS
Agent, after consultation with the Company, at or prior to the commencement of
the SPURS Mode (the "Base Rate"), plus the Applicable Spread (as defined below),
which will be based on the Dollar Price (as defined below) of the Notes.

         The "Applicable Spread" will be the lowest bid indication, expressed as
a spread (in the form of a percentage or in basis points) above the Base Rate,
obtained by the SPURS Agent on the Determination Date from the bids quoted by up
to five Reference Corporate Dealers (as defined below) for the full aggregate
principal amount of the Notes at the Dollar Price, but assuming (i) an issue
date equal to the SPURS Remarketing Date, with settlement on such date without
accrued interest, (ii) a maturity date equal to the next succeeding Interest
Adjustment Date of the Notes and (iii) a stated annual interest rate, payable
semiannually on each Interest Payment Date, equal to the Base Rate plus the
spread bid by the applicable Reference Corporate Dealer. If fewer than five
Reference Corporate Dealers bid as set forth in this subsection (b)(i) of
Section 303, then the Applicable Spread shall be the lowest of such bid
indications obtained as set forth in this subsection (b)(i) of Section 303. The
SPURS Interest Rate announced by the SPURS Agent, absent manifest error, shall
be binding and conclusive upon the Beneficial Owners and Holders of the Notes,
the Company and the Trustee.

         "Dollar Price" shall mean, with respect to the Notes, the present value
determined by the SPURS Agent, as of the SPURS Remarketing Date, of the
Remaining Scheduled Payments (as defined below) discounted to the SPURS
Remarketing Date, on a semi-annual basis (assuming a 360-day year consisting of
twelve 30-day months), at the Treasury Rate (as defined below).

         "Reference Corporate Dealers" means such Reference Corporate Dealers as
shall be appointed by the SPURS Agent after consultation with the Company.

         "Treasury Rate" shall mean, with respect to the SPURS Remarketing Date,
the rate per annum equal to the semi-annual equivalent yield to maturity or
interpolated (on a day count basis) yield to maturity of the Comparable Treasury
Issues (as defined below), assuming a price for the Comparable Treasury Issues
(expressed as a percentage of its principal amount), equal to the Comparable
Treasury Price (as defined below) for such SPURS Remarketing Date.

                                       28
<PAGE>   30

         "Comparable Treasury Issues" shall mean the United States Treasury
security or securities selected by the SPURS Agent as having an actual or
interpolated maturity or maturities comparable or applicable to the remaining
term to the next succeeding Interest Adjustment Date of the Notes being
purchased.

         "Comparable Treasury Price" means, with respect to the SPURS
Remarketing Date, (a) the offer prices for the Comparable Treasury Issues
(expressed in each case as a percentage of its principal amount) on the
Determination Date, as set forth on "Telerate Page 500" (or such other page as
may replace Telerate Page 500) or (b) if such page (or any successor page) is
not displayed or does not contain such offer prices on such Determination Date,
(i) the average of the Reference Treasury Dealer Quotations (as defined below)
for such SPURS Remarketing Date, after excluding the highest and lowest of such
Reference Treasury Dealer Quotations, or (ii) if the SPURS Agent obtains fewer
than four such Reference Treasury Dealer Quotations, the average of all such
Reference Treasury Dealer Quotations. "Telerate Page 500" means the display
designated as "Telerate Page 500" on Bridge Telerate, Inc. (or such other page
as may replace Telerate Page 500 on such service) or such other service
displaying the offer prices specified in (a) above as may replace Bridge
Telerate, Inc.

         "Reference Treasury Dealer Quotations" means, with respect to each
Reference Treasury Dealer and the SPURS Remarketing Date, the offer prices for
the Comparable Treasury Issues (expressed in each case as a percentage of its
principal amount) quoted in writing to the SPURS Agent by such Reference
Treasury Dealer by 3:30 p.m. New York City time, on the Determination Date.

         "Reference Treasury Dealer" means such Reference Treasury Dealers as
shall be appointed by the SPURS Agent after consultation with the Company.

         "Remaining Scheduled Payments" shall mean, with respect to the Notes,
the remaining scheduled payments of the principal thereof and interest thereon,
calculated at the Base Rate only, that would be due after the SPURS Remarketing
Date to and including the next succeeding Interest Adjustment Date as determined
by the SPURS Agent.

                  (ii) Notification of Results; Settlement. Provided the SPURS
Agent has previously notified the Company and the Trustee on the Notification
Date of its intention to purchase all tendered Notes on the SPURS Remarketing
Date, the SPURS Agent shall notify the Company, the Trustee and DTC by
telephone, confirmed in writing, by 4:00 p.m., New York City time, on the
Determination Date, of the SPURS Interest Rate.

         All of the tendered Notes shall be automatically delivered to the
account of the Trustee, by book-entry through DTC pending payment of the
purchase price therefor, on the SPURS Remarketing Date.

         In the event that the SPURS Agent purchases the tendered Notes on the
SPURS Remarketing Date, the SPURS Agent shall make or cause the Trustee to make
payment to the DTC Participant of each tendering Beneficial Owner of Notes, by
book-entry through DTC by

                                       29
<PAGE>   31

the close of business on the SPURS Remarketing Date against delivery through DTC
of such Beneficial Owner's tendered Notes, of 100% of the principal amount of
the tendered Notes that have been purchased for remarketing by the SPURS Agent.
If the SPURS Agent does not purchase all of the Notes on the SPURS Remarketing
Date, the Company may attempt to convert the Notes to a new Interest Rate Mode;
the interest will be determined as provided above in Section 204 and settlement
will be effected as described above in Section 207(b) or Section 207(c), as the
case may be. In any case, the Company shall make or cause the Trustee to make
payment of interest to each Beneficial Owner of Notes due on the SPURS
Remarketing Date by book-entry through DTC by the close of business on the SPURS
Remarketing Date.

         The transactions set forth in this Section 303 shall be executed on the
SPURS Remarketing Date through DTC in accordance with the procedures of DTC, and
the accounts of the respective DTC participants will be debited and credited and
the Notes delivered by book-entry as necessary to effect the purchases and sales
thereof.

         Transactions involving the sale and purchase of Notes remarketed by the
SPURS Agent on and after the SPURS Remarketing Date will settle in immediately
available funds through DTC's Same-Day Funds Settlement System.

         The tender and settlement procedures set forth above, including
provisions for payment by purchasers of Notes in the remarketing or for payment
to selling Beneficial Owners of tendered Notes, may be modified to the extent
required by DTC or to the extent required to facilitate the tender and
remarketing of Notes in certificated form, if the book-entry system is no longer
available for the Notes at the time of the remarketing. In addition, the SPURS
Agent may, without the consent of the Holders of the Notes, modify the
settlement procedures set forth above in order to facilitate the tender and
settlement process.

         As long as DTC's nominee holds the certificates representing any Notes
in the book-entry system of DTC, no certificates for such Notes will be
delivered by any selling Beneficial Owner to reflect any transfer of such Notes
effected in the remarketing.

                  Section 304. Conversion or Redemption Following Election by
the SPURS Agent to Remarket.

                  (a) If the SPURS Agent elects to remarket the Notes on the
SPURS Remarketing Date, the Notes will be subject to mandatory tender to the
SPURS Agent for remarketing on such date, in each case subject to the conditions
set forth in Section 303 hereof and to the Company's right to either convert the
Notes to a new Interest Rate Mode on the SPURS Remarketing Date or to redeem the
Notes from the SPURS Agent, in each case as described in the next sentence. The
Company will notify the SPURS Agent and the Trustee, not later than the Business
Day immediately preceding the Determination Date, if the Company irrevocably
elects to exercise its right to either convert the Notes to a new Interest Rate
Mode, or to redeem the Notes, in whole but not in part, from the SPURS Agent at
the Optional Redemption Price, in each case on the SPURS Remarketing Date.

                                       30
<PAGE>   32

                  (b) In the event that the Company irrevocably elects to
convert the Notes to a new Interest Rate Mode, then as of the SPURS Remarketing
Date the Notes will cease to be in the SPURS Mode, the SPURS Remarketing Date
will constitute an Interest Rate Adjustment Date, and the Notes will be subject
to remarketing on such date by a Remarketing Agent appointed by the Company in
the Commercial Paper Term Mode or the Long Term Rate Mode or a new SPURS Mode
established by the Company in accordance with the procedures set forth in
Section 205 above; provided that in such case, the notice period required for
conversion shall be the period commencing the Business Day immediately preceding
the Determination Date. In such case, the Company shall pay to the SPURS Agent
the excess of the Dollar Price of the Notes over 100% of the principal amount of
the Notes in same-day funds by wire transfer to an account designated by the
SPURS Agent on the SPURS Remarketing Date.

                  (c) In the event that the Company irrevocably elects to redeem
the Notes, the "Optional Redemption Price" shall be the greater of (i) 100% of
the principal amount of the Notes and (ii) the Dollar Price, plus in either case
accrued and unpaid interest from the SPURS Remarketing Date on the principal
amount being redeemed to the date of redemption. If the Company elects to redeem
the Notes, it shall pay the redemption price therefor in same-day funds by wire
transfer to an account designated by the SPURS Agent on the SPURS Remarketing
Date.

                  (d) If notice has been given as provided in the Original
Indenture and funds for the redemption of any Notes called for redemption shall
have been made available on the redemption date referred to in such notice, such
Notes shall cease to bear interest on the date fixed for such redemption
specified in such notice and the only right of the SPURS Agent from and after
the redemption date shall be to receive payment of the Optional Redemption Price
upon surrender of such Notes in accordance with such notice.

                                  ARTICLE FOUR

                                EVENTS OF DEFAULT

         With respect to the Notes, subject to the provisions of the Indenture
permitting amendment or modification in accordance, and subject to compliance,
with the terms thereof, Sections 501, 502, 503, and 504 of the Original
Indenture are replaced with and superseded by the following language:

                  "Section 501. Events of Default.

         "Event of Default", wherever used herein with respect to the Notes,
means any of the following events (whatsoever the reason for such Event of
Default and whether it shall be voluntary or involuntary or be effected by
operation of law or pursuant to any judgment, decree or order of any court or
any order, rule or regulation of any administrative or governmental body):

such interest becomes due and payable, and continuance of such default for a
period of 30 days; or

                  (2) default in the payment of the principal of (or any
premium, if any, on) any Note at its Maturity; or

                  "Section 502. Acceleration of Maturity: Rescission and

                  lawful, interest upon overdue interest at the rate or rates

shall cause the principal amount and accrued interest to become immediately due
and payable without any declaration or other act by the Trustee or any Holder."

                  "Section 503. Collection of Indebtedness and Suits for
Enforcement by Trustee.

         The Company covenants that if

                  (1)      default is made in payment of any interest on any
Note when such interest becomes due and payable and such default continues for a
period of 30 days, or

                  (2)      default is made in the payment of the principal of
(or premium, if any, on) any Note at the Maturity thereof,

the Company will, upon demand of the Trustee, pay to it, for the benefit of the
Holders of such Notes, the whole amount then due and payable on such Notes for
principal (and premium, if any) and interest and, to the extent that payment of
such interest shall be legally enforceable, interest on any overdue principal
(and premium, if any) and on any overdue interest, at the rate or rates
prescribed therefor in such Notes and, in addition thereto, such further amount
as shall be sufficient to cover the costs and expenses of collection, including
the reasonable compensation, expenses, disbursements and advances of the
Trustee, its agents and counsel.

         If the Company fails to pay such amounts forthwith upon such demand,
the Trustee, in its own name and as trustee of an express trust, may institute a
judicial proceeding for the collection of the sums so due and unpaid, may
prosecute such proceeding to judgment or final decree and

                                       34

may enforce the same against the Company or any other obligor upon such Notes
and collect the moneys adjudged or decreed to be payable in the manner provided
by law out of the property of the Company or any other obligor upon such Notes,
wherever situated.

         If an Event of Default occurs and is continuing with respect to the
Notes, the Trustee may in its discretion proceed to protect and enforce its
rights, including the rights of the Holders of the Notes, by such appropriate
judicial proceedings as the Trustee shall deem most effectual to protect and
enforce any such rights, whether for the specific enforcement of any covenant or
agreement in this Indenture or in aid of the exercise of any power granted
herein, or to enforce any other proper remedy including, without limitation,
instituting a proceeding prior to any declaration of acceleration of the
Maturity of the Notes for the collection of all amounts then due and unpaid on
the Notes, prosecuting such proceeding to final judgment or decree and
collecting out of the property, wherever situated, of the Company the moneys
adjudged or decreed to be payable in the manner provided by law."

                  "Section 504. Trustee May File Proofs of Claim.

         In case of the pendency of any receivership, insolvency, liquidation,
bankruptcy, reorganization, arrangement, adjustment, composition or other
judicial proceeding relative to the Company or DECO or any other obligor upon
the Notes or the property of the Company or of such other obligor or their
creditors, the Trustee (irrespective of whether the principal of the Notes shall
then be due and payable as therein expressed or by declaration or otherwise and
irrespective of whether the Trustee shall have made any demand on the Company
for the payment of any overdue principal or interest) shall be entitled and
empowered, by intervention in such proceeding or otherwise,

                  (i)  to file and prove a claim for the whole amount of
         principal (and premium, if any) and interest owing and unpaid in
         respect of the Notes and to file such other papers or documents as may
         be necessary or advisable in order to have the claims of the Trustee
         (including any claim for the reasonable compensation, expenses,
         disbursements and advances of the Trustee, its agents and counsel) and
         of the Holders of Notes allowed in such judicial proceeding, and

                  (ii) to collect and receive any moneys or other property
         payable or deliverable on any such claims and to distribute the same;

and any custodian, receiver, assignee, trustee, liquidator, sequestrator or
other similar official in any such Judicial proceeding is hereby authorized by
each Holder of Notes to make such payments to the Trustee and, in the event that
the Trustee shall consent to the making of such payments directly to the Holders
of Notes, to pay to the Trustee any amount due it for the reasonable
compensation, expenses, disbursements and advances of the Trustee, its agents
and counsel, and any other amounts due the Trustee under Section 606.

         Nothing herein contained shall be deemed to authorize the Trustee to
authorize or consent to or accept or adopt on behalf of any Holder of a Note any
plan of reorganization, arrangement,

thereof or to authorize the Trustee to vote in respect of the claim of any
Holder of a Note in any such proceeding."

Notes, the reference in Section 601 of the Original Indenture to Section 501 (4)

Interest Rate Period, the Notes shall be entitled to the benefit of a Policy
issued by the Insurer. The form of Policy with respect to the Initial Interest

payments thereunder.

                  Section 802. Rights of Insurer Controlling. Anything herein or
under the Original Indenture to the contrary notwithstanding, if a Policy is in
effect with respect to the Notes and the Insurer is not in default of its
obligation to make payments thereunder, the Insurer shall be deemed to be the
Holder of all Notes then Outstanding for all purposes under the Indenture and
shall have the exclusive right to exercise or direct the exercise of remedies on
behalf of the Holders of the Notes in accordance with the terms of the Indenture
following an Event of Default, and the principal of all such Notes Outstanding
may not be declared to be due and payable immediately without the prior written
consent of the Insurer.

                  Section 803. Payments Under the Policy in Respect of the

Interest Payment Date in the Initial Interest Rate Period, through and including
the Initial Interest Rate Adjustment Date, the Trustee has not received payments

so that sufficient moneys are available under this First Supplemental Indenture
to pay all interest due on the Notes on such Interest Payment Date, the Trustee
shall promptly notify the Insurer or its designee by telephone, confirmed in
writing by registered or certified mail, of the amount of the deficiency.

                  (b) If, as of 3:00 p.m. New York City time, on the Initial

pursuant to a final judgment by a court of competent jurisdiction that such
payment constitutes a voidable preference to such Holders within the

meaning of any applicable bankruptcy laws, then the Trustee shall notify the
Insurer or its designee of such fact by telephone, confirmed in writing by

appointed, directed and authorized to act as attorney-in-fact for Holders of the
Notes as follows:

         If and to the extent there is a deficiency in amounts required to pay
interest on the Notes, the Trustee shall (A) execute and deliver to State Street
Bank and Trust Company, N.A., or its successors under the Policy (the "Insurance

                  makes payments, directly or indirectly (as by paying through

                  will be subrogated to the rights of such Holders to receive
                  the amount of such interest from the Company, with interest
                  thereon as provided and solely from the sources stated in this

                           (ii) they will accordingly pay to the Insurer the
                  amount of such interest (including interest recovered under
                  subparagraph (ii) of the first paragraph of the Policy, which
                  interest shall be deemed past due and not to have been paid),
                  with interest thereon as provided in this First Supplemental
                  Indenture and the Note, but only from the sources and in the
                  manner provided herein for the payment of interest on the
                  Notes to Holders and will otherwise treat the Insurer as the
                  owner of such rights to the amount of such interest.

                  (g)      On the date of purchase, the Company shall execute

subsequent Interest Rate Period, so long as a Policy is in effect with respect

not in effect.

                  Section 811. Copies of Financial Statements. The Insurer shall

         THIS NOTE SHALL NOT BE VALID FOR ANY PURPOSE UNLESS PRESENTED TOGETHER
WITH ANNEX A HERETO (INCLUDING ANY CONTINUATION THEREOF). REFERENCE IS MADE TO
ANNEX A FOR CERTAIN TERMS OF THIS NOTE.

         DTE ENERGY COMPANY, a corporation duly organized and existing under the
laws of the State of Michigan (the "Company"), for value received hereby
promises to pay to CEDE & CO., or registered assigns, the principal sum
specified in Annex A on June 15, 2038 (the "Stated Maturity"), upon the
presentation and surrender hereof at the principal corporate trust office of The
Bank of New York, or its successor in trust (the "Trustee") or such other office
as the Trustee has designated in writing, and to pay interest on the unpaid
principal balance hereof from, and including, the Original Issue Date specified
in Annex A to, but excluding, the Initial Interest Rate Adjustment Date
specified in Annex A (the "Initial Interest Rate Period") at the Initial
Interest Rate specified therein payable on the related Interest Payment Date or
Dates specified in Annex A, to the person in whose name this Note is registered
at the close of business on the related Record Date. From and after the Initial
Interest Rate Adjustment Date, this Note will bear interest in either the
Commercial Paper Term Mode, the Long Term Rate Mode or the SPURS Mode, in each
case as provided in this Note and set forth in Annex A, and interest will be
payable on the Interest Payment Dates to the person in whose name this Note is
registered at the close of business on the related Record Date as provided below
or as set forth in Annex A. In each case, payments shall be made in accordance
with the provisions hereof and Annex A, including any additional terms specified
in Annex A, until the principal hereof is paid or duly made available for
payment. References herein to "this Note", "hereof", "herein" and comparable
terms shall include Annex A.

         So long as this Note bears interest in the Commercial Paper Term Mode,
interest will be payable on the Interest Rate Adjustment Date which commences
the next succeeding Interest Rate Period for this Note and on such other dates
(if any) as will be established by the Company and set forth in Annex A upon
conversion of this Note to the Commercial Paper Term Mode or upon remarketing of
this Note in a new Interest Rate Period in the Commercial Paper Term Mode. So
long as this Note bears interest in the Long Term Rate Mode or the SPURS Mode,
interest will be payable no less frequently than semiannually on such dates as
will be established by the Company and set forth in Annex A upon conversion of
this Note to the Long Term Rate Mode or the SPURS Mode (or upon remarketing of
this Note in a new Interest Rate Period in the Long Term Rate Mode or the SPURS
Mode, as the case may be) in the case of a fixed interest rate, or as set forth
below under "Interest Rate" in the case of a floating interest rate and on the
Interest Rate Adjustment Date commencing the next succeeding Interest Rate
Period. Such

                                       A-4

interest will be payable to the Holder hereof as of the related Record Date,
which, so long as this Note bears interest (i) in the Initial Interest Rate
Period, are the dates specified in Annex A; (ii) in the Commercial Paper Term
Mode, is the Business Day prior to the related Interest Payment Date; and (iii)
in the Long Term Rate Mode or the SPURS Mode, is 15 days prior to the related
Interest Payment Date. Except as provided below under "Interest Rate-Floating
Interest Rates," if any Interest Payment Date would otherwise be a day that is
not a Business Day, such Interest Payment Date will be postponed to the next
succeeding Business Day, and no interest will accrue on such payment for the
period from and after such Interest Payment Date to the date of such payment on
the next succeeding Business Day. Interest on this Note while bearing interest
in the Commercial Paper Term Mode or at a floating interest rate during a Long
Term Rate Period or a SPURS Rate Period will be computed on the basis of actual
days elapsed over 360; provided that, if an applicable Interest Rate Basis is
the CMT Rate or Treasury Rate (each as defined below), interest will be computed
on the basis of actual days elapsed over the actual number of days in the year.
Interest on this Note while bearing interest in the Long Term Rate Mode or the
SPURS Mode will be computed on the basis of a year of 360 days consisting of
twelve 30-day months. Interest on this Note while bearing interest at the
Initial Interest Rate will be computed on the basis a year of 360 days
consisting of twelve 30-day months.

         Payment of the principal of and interest on this Note will be made at
the office or agency maintained for that purpose in the Borough of Manhattan,
The City of New York, 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; provided, however, that payment of interest may be made at the option of
the Company by check mailed to the person in whose name this Note is registered
at the close of business on the related Record Date.

         This Note is one of a duly authorized series of Securities of the
Company (herein called the "Notes") issued and to be issued under an Indenture,

Remarketing Agent, to produce a par bid in the secondary market for this Note on

         (c) Floating Interest Rates. While this Note bears interest in the Long
Term Rate Mode or the SPURS Mode (with respect to the period from, and
including, the Interest Rate Adjustment Date commencing such period to, but
excluding, the SPURS Remarketing Date), the Company may elect a floating
interest rate by providing notice, which will be in or promptly confirmed in
writing (which includes facsimile or appropriate electronic media), received by
the Trustee and the Remarketing Agent for this Note (the "Floating Interest Rate
Notice") not less than ten (10) days prior to the Interest Rate Adjustment Date
for such Long Term Rate Period or SPURS Rate Period. The Floating Interest Rate
Notice must identify by CUSIP number or otherwise the portion of this Note to
which it relates and state the Interest Rate Period (or portion thereof, in the
case of the SPURS Mode) therefor to which it relates. Each Floating Interest
Rate Notice must also state the Interest Rate Basis or Bases, the Initial
Interest Reset Date, the Interest Reset Period and Dates, the Interest Payment
Period and Dates, the Index Maturity, the Floating Rate Maximum Interest Rate
and/or Floating Rate Minimum Interest Rate, if any, and the Day Count
Convention. If one or more of the applicable Interest Rate Bases is LIBOR or the
CMT Rate, the Floating Interest Rate Notice shall also specify the Index
Currency and Designated LIBOR Page or the Designated CMT Maturity Index and
Designated CMT Telerate Page, respectively.

         If this Note bears interest at a floating rate in a Long Term Rate
Period or a SPURS Rate Period, this Note shall bear interest at the rate
determined by reference to the applicable Interest Rate Basis or Bases (a) plus
or minus the Spread, if any, and/or (b) multiplied by the Spread Multiplier, if
any, specified by the Remarketing Agent, in the case of a Long Term Rate Period,
or the SPURS Agent in the case of a SPURS Rate Period, and recorded in Annex A
to this Note. Commencing on the Interest Rate Adjustment Date for such Interest
Rate Period, the rate at which interest on this Note shall be payable shall be
reset as of each Interest Reset Date during such Interest Rate Period specified
in the applicable Floating Interest Rate Notice.

         The applicable floating interest rate on this Note during any Interest
Rate Period will be determined by reference to the applicable Interest Rate
Basis or Interest Rate Bases, which may include (i) the CD Rate, (ii) the CMT
Rate, (iii) the Federal Funds Rate, (iv) LIBOR, (v) the Prime Rate, (vi) the
Treasury Rate, or (vii) such other Interest Rate Basis or interest rate formula
as may be specified in the applicable Floating Interest Rate Notice (each, an
"Interest Rate Basis").

         Unless otherwise specified in the applicable Floating Interest Rate
Notice, the interest rate with respect to each Interest Rate Basis will be
determined in accordance with the applicable provisions below. Except as set
forth above or specified in the applicable Floating Interest Rate Notice, the
interest rate in effect on each day shall be (i) if such day is an Interest
Reset Date, the interest rate determined as of the Interest Determination Date
immediately preceding such Interest Reset Date or (ii) if such day is not an
Interest Reset Date, the interest rate determined as

                                      A-12
<PAGE>   56

of the Interest Determination Date immediately preceding the most recent
Interest Reset Date. If any Interest Reset Date would otherwise be a day that is
not a Business Day, such Interest Reset Date shall be postponed to the next
succeeding Business Day, except that if LIBOR is an applicable Interest Rate
Basis and such Business Day falls in the next succeeding calendar month, such
Interest Reset Date shall be the immediately preceding Business Day. In
addition, if the Treasury Rate is an applicable Interest Rate Basis and the
Interest Determination Date would otherwise fall on an Interest Reset Date, then
such Interest Reset Date will be postponed to the next succeeding Business Day.

         The applicable Floating Interest Rate Notice will specify whether the
rate of interest will be reset daily, weekly, monthly, quarterly, semiannually
or annually or on such other specified basis (each, an "Interest Reset Period")
and the dates on which such rate of interest will be reset (each, an "Interest
Reset Date"). Unless otherwise specified in the applicable Floating Interest
Rate Notice, the Interest Reset Dates will be, in the case of a floating
interest rate which resets: (i) daily, each Business Day; (ii) weekly, the
Wednesday of each week (unless the Treasury Rate is an applicable Interest Rate
Basis, in which case the Tuesday of each week except as described below); (iii)
monthly, the third Wednesday of each month; (iv) quarterly, the third Wednesday
of March, June, September and December of each year, (v) semiannually, the third
Wednesday of the two months specified in the applicable Floating Interest Rate
Notice; and (vi) annually, the third Wednesday of the month specified in the
applicable Floating Interest Rate Notice.

         The interest rate applicable to each Interest Reset Period commencing
on the related Interest Reset Date will be determined as of the applicable
Interest Determination Date. The "Interest Determination Date" with respect to
the Federal Funds Rate and the Prime Rate will be the Business Day immediately
preceding the applicable Interest Reset Date; the "Interest Determination Date"
with respect to the CD Rate and the CMT Rate will be the second Business Day
immediately preceding the applicable Interest Reset Date; and the "Interest
Determination Date" with respect to LIBOR shall be the second London Business
Day immediately preceding the applicable Interest Reset Date, unless the Index
Currency is British pounds sterling, in which case the "Interest Determination
Date" will be the applicable Interest Reset Date. The "Interest Determination
Date" with respect to the Treasury Rate shall be the day in the week in which
the applicable Interest Reset Date falls on which day Treasury Bills (as defined
below) are normally auctioned (Treasury Bills are normally sold at an auction
held on Monday of each week, unless such Monday is a legal holiday, in which
case the auction is normally held on the immediately succeeding Tuesday,
although such auction may be held on the preceding Friday); provided, however,
that if an auction is held on the Friday of the week preceding the applicable
Interest Reset Date, the "Interest Determination Date" shall be such preceding
Friday; provided, further, that if the Interest Determination Date would
otherwise fall on an Interest Reset Date, then such Interest Reset Date will be
postponed to the next succeeding Business Day. The "Interest Determination Date"
pertaining to this Note, the interest rate of which is determined with reference
to two or more Interest Rate Bases specified in the applicable Floating Interest
Rate Notice, shall be the most recent Business Day which is at least two
Business Days prior to the applicable Interest Reset Date on which each Interest
Rate Basis is determinable. Each Interest

                                      A-13
<PAGE>   57

Rate Basis shall be determined as of such date, and the applicable interest rate
shall take effect on the applicable Interest Reset Date.

         Either or both of the following may also apply to the floating interest
rate on this Note for an Interest Rate Period: (i) a floating rate maximum
interest rate, or ceiling, that may accrue during any Interest Reset Period (the
"Floating Rate Maximum Interest Rate") and (ii) a floating rate minimum interest
rate, or floor, that may accrue during any Interest Reset Period (the "Floating
Rate Minimum Interest Rate"). In addition to any Floating Rate Maximum Interest
Rate that may apply, the interest rate on this Note will in no event be higher
than the maximum rate permitted by New York law, as the same may be modified by
United States laws of general application.

         Except as provided below or in the applicable Floating Interest Rate
Notice, interest will be payable, in the case of floating interest rates which
reset: (i) daily, weekly or monthly, on the third Wednesday of each month or on
the third Wednesday of March, June, September and December of each year, as
specified in the applicable Floating Interest Rate Notice; (ii) quarterly, on
the third Wednesday of March, June, September and December of each year; (iii)
semiannually, on the third Wednesday of the two months of each year specified in
the applicable Floating Interest Rate Notice; and (iv) annually, on the third
Wednesday of the month of each year specified in the applicable Floating
Interest Rate Notice and, in each case, on the Business Day immediately
following the applicable Long Term Rate Period or SPURS Rate Period, as the case
may be. If any Interest Payment Date for the payment of interest at a floating
rate (other than following the end of the applicable Long Term Rate Period or
SPURS Rate Period, as the case may be) would otherwise be a day that is not a
Business Day, such Interest Payment Date will be postponed to the next
succeeding Business Day, except that if LIBOR is an applicable Interest Rate
Basis and such Business Day falls in the next succeeding calendar month, such
Interest Payment Date will be the immediately preceding Business Day.

         All percentages resulting from any calculation of floating interest
rates will be rounded to the nearest one hundred-thousandth of a percentage
point, with five one-millionths of a percentage point rounded upwards (e.g.,
9.876545% (or .09876545) would be rounded to 9.87655% (or .0987655)), and all
amounts used in or resulting from such calculation will be rounded, in the case
of United States dollars, to the nearest cent or, in the case of a foreign
currency or composite currency, to the nearest unit (with one-half cent or unit
being rounded upwards).

         Accrued floating rate interest will be calculated by multiplying the
principal amount of the applicable Note by an accrued interest factor. Such
accrued interest factor will be computed by adding the interest factor
calculated for each day in the applicable Interest Reset Period. Unless
otherwise specified in the applicable Floating Interest Rate Notice, the
interest factor for each such day will be computed by dividing the interest rate
applicable to such day by 360, if an applicable Interest Rate Basis is the CD
Rate, the Federal Funds Rate, LIBOR or the Prime Rate, or by the actual number
of days in the year if an applicable Interest Rate Basis is the CMT Rate or the
Treasury Rate. Unless otherwise specified in the applicable Floating Interest
Rate Notice,

                                      A-14
<PAGE>   58

if the floating interest rate is calculated with reference to two or more
Interest Rate Bases, the interest factor will be calculated in each period in
the same manner as if only one of the applicable Interest Rate Bases applied as
specified in the applicable Floating Interest Rate Notice.

         Unless otherwise specified in the applicable Floating Interest Rate
Notice, The Bank of New York will be the "Calculation Agent." For any Remarketed
Note bearing interest at a floating rate, the applicable Remarketing Agent will
determine the interest rate in effect from the Interest Rate Adjustment Date for
such Remarketed Note to the Initial Interest Reset Date. The Calculation Agent
will determine the interest rate in effect for each Interest Reset Period
thereafter. Upon request of the Beneficial Owner of a Note, after any Interest
Rate Adjustment Date, the Calculation Agent or the Remarketing Agent shall
disclose the interest rate and, in the case of a floating interest rate,
Interest Rate Basis or Bases, Spread (if any) and Spread Multiplier (if any),
and in each case the other terms applicable to such Note then in effect and, if
determined, the interest rate that will become effective as a result of a
determination made for the next succeeding Interest Reset Date with respect to
such Note. Except as described herein with respect to a Note earning interest at
floating rates, no notice of the applicable interest rate, Spread (if any) or
Spread Multiplier (if any) shall be sent to the Beneficial Owner of any Note.

         Unless otherwise specified in the applicable Floating Interest Rate
Notice, the "Calculation Date", if applicable, pertaining to any Interest
Determination Date will be the earlier of (i) the tenth calendar day after such
Interest Determination Date or, if such day is not a Business Day, the next
succeeding Business Day or (ii) the Business Day immediately preceding the
applicable Interest Payment Date or Maturity, as the case may be.

         CD Rate. If an Interest Rate Basis for this Note is specified in the
applicable Floating Interest Rate Notice as the CD Rate, the CD Rate shall be
determined as of the applicable Interest Determination Date (a "CD Rate Interest
Determination Date") as the rate on such date for negotiable United States
dollar certificates of deposit having the Index Maturity specified in the
applicable Floating Interest Rate Notice as published in H.15(519) (as defined
below) under the heading "CDs (secondary market)", or, if not so published by
3:00 P.M., New York City time, on the related Calculation Date, the rate on such
CD Rate Interest Determination Date for negotiable United States dollar
certificates of deposit of the Index Maturity as published in H.15 Update (as
defined herein), or such other recognized electronic source used for the purpose
of displaying such rate, under the caption "CDs (secondary market)." If such
rate is not yet published in either H.15(519), H.15 Daily Update or another
recognized electronic source by 3:00 P.M., New York City time, on the related
Calculation Date, then the CD Rate on such CD Rate Interest Determination Date
will be calculated by the Calculation Agent and will be the arithmetic mean of
the secondary market offered rates as of 10:00 A.M., New York City time, on such
CD Rate Interest Determination Date, of three leading nonbank dealers in
negotiable United States dollar certificates of deposit in The City of New York
(which may include the Remarketing Agent or its affiliates) selected by the
Calculation Agent, after consultation with the Company, for negotiable United
States dollar certificates of deposit of major United States money center banks
for negotiable United States dollar certificates of deposit with a remaining

                                      A-15
<PAGE>   59

maturity closest to the Index Maturity in an amount that is representative for a
single transaction in that market at that time; provided, however, that if the
dealers so selected by the Calculation Agent are not quoting as mentioned in
this sentence, the CD Rate determined as of such CD Rate Interest Determination
Date will be the CD Rate in effect on such CD Rate Interest Determination Date.

         "H.15(519)" means the weekly statistical release designated as such, or
any successor publication, published by the Board of Governors of the Federal
Reserve System.

         "H.15 Daily Update" means the daily update of H.15(519), available
through the world-wide-web site of the Board of Governors of the Federal Reserve
System at http://www.bog.frb.fed.us/releases/h15/update, or any successor site
or publication.

         CMT Rate. If an Interest Rate Basis for this Note is specified in the
applicable Floating Interest Rate Notice as the CMT Rate, the CMT Rate shall be
determined as of the applicable Interest Determination Date (a "CMT Rate
Interest Determination Date") as the rate displayed on the Designated CMT
Telerate Page (as defined below) under the caption "...Treasury Constant
Maturities...Federal Reserve Board Release H.15...Mondays Approximately 3:45
P.M.", under the column for the Designated CMT Maturity Index (as defined below)
for (i) if the Designated CMT Telerate Page is 7051, such CMT Rate Interest
Determination Date and (ii) if the Designated CMT Telerate Page is 7052, the
weekly or monthly average, as specified in the applicable Floating Interest Rate
Notice, for the week or the month, as applicable, ended immediately preceding
the week or the month, as applicable, in which the related CMT Rate Interest
Determination Date falls. If such rate is no longer displayed on the relevant
page or is not so displayed by 3:00 P.M., New York City time, on the related
Calculation Date, then the CMT Rate for such CMT Rate Interest Determination
Date will be such treasury constant maturity rate for the Designated CMT
Maturity Index as published in H.15(519). If such rate is no longer published or
is not published by 3:00 P.M., New York City time, on the related Calculation
Date, then the CMT Rate on such CMT Rate Interest Determination Date will be
such treasury constant maturity rate for the Designated CMT Maturity Index (or
other United States Treasury rate for the Designated CMT Maturity Index) for the
CMT Rate Interest Determination Date with respect to such Interest Reset Date as
may then be published by either the Board of Governors of the Federal Reserve
System or the United States Department of the Treasury that the Calculation
Agent determines to be comparable to the rate formerly displayed on the
Designated CMT Telerate Page and published in H.15(519). If such information is
not provided by 3:00 P.M., New York City time, on the related Calculation Date,
then the CMT Rate on the CMT Rate Interest Determination Date will be calculated
by the Calculation Agent and will be a yield to maturity, based on the
arithmetic mean of the secondary market bid prices as of approximately 3:30
P.M., New York City time, on such CMT Rate Interest Determination Date reported,
according to their written records, by three leading primary United States
government securities dealers in The City of New York (which may include the
Remarketing Agent or its affiliates) (each, a "Reference Dealer") selected by
the Calculation Agent, after consultation with the Company, (from five such
Reference Dealers selected by the Calculation Agent, after consultation with the
Company, and eliminating the highest quotation (or, in the event of equality,
one of the highest) and the lowest quotation (or, in the event of

                                      A-16
<PAGE>   60

equality, one of the lowest)), for the most recently issued direct noncallable
fixed rate obligations of the United States ("Treasury Notes") with an original
maturity of approximately the Designated CMT Maturity Index and a remaining term
to maturity of not less than such Designated CMT Maturity Index minus one year.
If the Calculation Agent is unable to obtain three such Treasury Note
quotations, the CMT Rate on such CMT Rate Interest Determination Date will be
calculated by the Calculation Agent and will be a yield to maturity based on the
arithmetic mean of the secondary market bid prices as of approximately 3:30
P.M., New York City time, on such CMT Rate Interest Determination Date of three
Reference Dealers in The City of New York (from five such Reference Dealers
selected by the Calculation Agent, after consultation with the Company, and
eliminating the highest quotation (or, in the event of equality, one of the
highest) and the lowest quotation (or, in the event of equality, one of the
lowest)), for Treasury Notes with an original maturity of the number of years
that is the next highest to the Designated CMT Maturity Index and a remaining
term to maturity closest to the Designated CMT Maturity Index and in an amount
of at least U.S.$100 million. If three or four (and not five) of such Reference
Dealers are quoting as described above, then the CMT Rate will be based on the
arithmetic mean of the bid prices obtained and neither the highest nor the
lowest of such quotes will be eliminated; provided, however, that if fewer than
three Reference Dealers so selected by the Calculation Agent, after consultation
with the Company, are quoting as mentioned herein, the CMT Rate determined as of
such CMT Rate Interest Determination Date will be the CMT Rate in effect on such
CMT Rate Interest Determination Date. If two Treasury Notes with an original
maturity as described in the second preceding sentence have remaining terms to
maturity equally close to the Designated CMT Maturity Index, the Calculation
Agent will obtain quotations for the Treasury Note with the shorter remaining
term to maturity.

         "Designated CMT Maturity Index" means the original period to maturity
of the U.S. Treasury securities (either 1, 2, 3, 5, 7, 10, 20 or 30 years)
specified in the applicable Floating Interest Rate Notice with respect to which
the CMT Rate will be calculated or, if no such maturity is specified in the
applicable Floating Interest Rate Notice, 2 years.

         "Designated CMT Telerate Page" means the display on the Bridge
Telerate, Inc. (or any successor service) on the page specified in the
applicable Floating Interest Rate Notice (or any other page as may replace such
page on such service for the purpose of displaying Treasury Constant Maturities
as reported in H.15(519) or, if no such page is specified in the applicable
Floating Interest Rate Notice, page 7052.

         Federal Funds Rate. If an Interest Rate Basis for this Note is
specified in the applicable Floating Interest Rate Notice as the Federal Funds
Rate, the Federal Funds Rate shall be determined as of the applicable Interest
Determination Date (a "Federal Funds Rate Interest Determination Date"), the
rate on such date for United States dollar federal funds as published in
H.15(519) under the heading "Federal Funds (Effective)", as such rate is
displayed on Bridge Telerate, Inc. or any successor service on page 120 (or any
other page as may replace such page on such service) ("Telerate Page 120"), or,
if such rate does not appear on Telerate Page 120 or is not so published by 3:00
P.M., New York City time, on the related Calculation Date, the rate

                                      A-17
<PAGE>   61

on such Federal Funds Rate Interest Determination Date for United States dollar
federal funds as published in H.15 Daily Update, or such other recognized
electronic source used for the purpose of displaying such rate, under the
caption "Federal Funds (Effective)." If such rate does not appear on Telerate
Page 120 or is not yet published in H.15(519), H.15 Daily Update or another
recognized electronic source by 3:00 P.M., New York City time, on the related
Calculation Date, then the Federal Funds Rate on such Federal Funds Rate
Interest Determination Date will be calculated by the Calculation Agent and will
be the arithmetic mean of the rates for the last transaction in overnight United
States dollar federal funds arranged by three leading brokers of United States
dollar federal funds transactions in The City of New York (which may include the
Remarketing Agent or its affiliates) selected by the Calculation Agent, after
consultation with the Company, prior to 9:00 A.M., New York City time, on such
Federal Funds Rate Interest Determination Date; provided, however, that if the
brokers so selected by the Calculation Agent are not quoting as mentioned in
this sentence, the Federal Funds Rate determined as of such Federal Funds Rate
Interest Determination Date will be the Federal Funds Rate in effect on such
Federal Funds Rate Interest Determination Date.

         LIBOR. If an Interest Rate Basis for this Note is specified in the
applicable Floating Interest Rate Notice as LIBOR, LIBOR shall be determined by
the Calculation Agent as of the applicable Interest Determination Date (a "LIBOR
Interest Determination Date") in accordance with the following provisions:

         (i)  With respect to any Interest Determination Date relating to a
Floating Rate Note for which the interest rate is determined with reference to
LIBOR (a "LIBOR Interest Determination Date"), LIBOR will be either: (a) if
"LIBOR Telerate" is specified in the applicable Floating Interest Rate Notice or
if neither "LIBOR Reuters" nor "LIBOR Telerate" is specified in the applicable
Floating Interest Rate Notice as the method for calculating LIBOR, the rate for
deposits in the Index Currency having the Index Maturity specified in the
applicable Floating Interest Rate Notice, commencing on such Interest Reset
Date, that appears on the Designated LIBOR Page as of 11:00 A.M., London time,
on such LIBOR Interest Determination Date; or (b) if "LIBOR Reuters" is
specified in the applicable Floating Interest Rate Notice, the arithmetic mean
of the offered rates (unless the Designated LIBOR Page by its terms provides
only for a single rate, in which case such single rate shall be used) for
deposits in the Index Currency having the Index Maturity specified in the
applicable Floating Interest Rate Notice, commencing on the applicable Interest
Reset Date, that appear (or, if only a single rate is required as aforesaid,
appears) on the Designated LIBOR Page as of 11:00 A.M., London time, on such
LIBOR Interest Determination Date. If fewer than two such offered rates so
appear, or if no such rate so appears, as applicable, LIBOR on such LIBOR
Interest Determination Date will be determined in accordance with the provisions
described in clause (ii) below.

         (ii) With respect to a LIBOR Interest Determination Date on which fewer
than two offered rates appear, or no rate appears, as the case may be, on the
Designated LIBOR Page as specified in clause (i) above, the Calculation Agent
will request the principal London offices of each of four major reference banks
(which may include affiliates of the Remarketing Agent) in the London interbank
market, as selected by the Calculation Agent, after consultation with the

                                      A-18
<PAGE>   62

Company, to provide the Calculation Agent with its offered quotation for
deposits in the Index Currency for the period of the Index Maturity specified in
the applicable Floating Interest Rate Notice, commencing on the applicable
Interest Reset Date, to prime banks in the London interbank market at
approximately 11:00 A.M., London time, on such LIBOR Interest Determination Date
and in a principal amount that is representative for a single transaction in the
Index Currency in such market at such time. If at least two such quotations are
so provided, then LIBOR on such LIBOR Interest Determination Date will be the
arithmetic mean of such quotations. If fewer than two such quotations are so
provided, then LIBOR on such LIBOR Interest Determination Date will be the
arithmetic mean of the rates quoted at approximately 11:00 A.M., in the
applicable Principal Financial Center, on such LIBOR Interest Determination Date
by three major banks (which may include affiliates of the Remarketing Agent) in
such Principal Financial Center selected by the Calculation Agent, after
consultation with the Company, for loans in the Index Currency to leading
European banks, having the Index Maturity specified in the applicable Floating
Interest Rate Notice and in a principal amount that is representative for a
single transaction in the Index Currency in such market at such time; provided,
however, that if the banks so selected by the Calculation Agent are not quoting
as mentioned in this sentence, LIBOR determined as of such LIBOR Interest
Determination Date will be LIBOR in effect on such LIBOR Interest Determination
Date.

         "Index Currency" means the currency specified in the applicable
Floating Interest Rate Notice as to which LIBOR shall be calculated or, if no
such currency is specified in the applicable Floating Interest Rate Notice,
United States dollars.

         "Designated LIBOR Page" means (a) if "LIBOR Reuters" is specified in
the applicable Floating Interest Rate Notice, the display on the Reuter Monitor
Money Rates Service (or any successor service) on the page specified in the
applicable Floating Interest Rate Notice (or any other page as may replace such
page on such service) for the purpose of displaying the London interbank rates
of major banks for the Index Currency, or (b) if "LIBOR Telerate" is specified
in the applicable Floating Interest Rate Notice or neither "LIBOR Reuters" nor
"LIBOR Telerate" is specified in the applicable Floating Interest Rate Notice as
the method for calculating LIBOR, the display on Bridge Telerate, Inc. (or any
successor service) on the page specified in the applicable Floating Interest
Rate Notice (or any other page as may replace such page on such service) for the
purpose of displaying the London interbank rates of major banks for the Index
Currency.

         Prime Rate. If an Interest Rate Basis for this Note is specified on the
face hereto as the Prime Rate, the Prime Rate shall be determined as of the
applicable Interest Determination Date (a "Prime Rate Interest Determination
Date") as the rate on such date as such rate is published in H.15(519) under the
caption "Bank Prime Loan" or, if not published by 3:00 P.M., New York City time,
on the related Calculation Date, the rate on such Prime Rate Interest
Determination Date as published in H.15 Daily Update, or such other recognized
electronic source used for the purpose of displaying such rate under the caption
"Bank Prime Loan." If such rate is not yet published in H.15(519), H.15 Daily
Update or another recognized electronic source by 3:00 P.M., New York City time,
on the related Calculation Date, then the Prime Rate shall be the

                                      A-19
<PAGE>   63

arithmetic mean of the rates of interest publicly announced by each bank that
appears on the Reuters Screen US PRIME1 Page (as defined below) as such bank's
prime rate or base lending rate as of 11:00 A.M. New York City time, on such
Prime Rate Interest Determination Date. If fewer than four such rates so appear
on the Reuters Screen US PRIME1 Page for such Prime Rate Interest Determination
Date, then the Prime Rate shall be the arithmetic mean of the prime rates or
base lending rates quoted on the basis of the actual number of days in the year
divided by a 360-day year as of the close of business on such Prime Rate
Interest Determination Date by three major banks (which may include The Bank of
New York or affiliates of the Remarketing Agent) in The City of New York
selected by the Calculation Agent, after consultation with the Company;
provided, however, that if the banks or trust companies so selected by the
Calculation Agent are not quoting as mentioned in this sentence, the Prime Rate
determined as of such Prime Rate Interest Determination Date will be the Prime
Rate in effect on such Prime Rate Interest Determination Date.

         "Reuters Screen US PRIME1 Page" means the display on the Reuter Monitor
Money Rates Service (or any successor service) on the "US PRIME1" page (or such
other page as may replace the US PRIME1 page on such service) for the purpose of
displaying prime rates or base lending rates of major United States banks.

         Treasury Rate. If an Interest Rate Basis for this Note is specified in
the applicable Floating Interest Rate Notice as the Treasury Rate, the Treasury
Rate shall be determined as of the applicable Interest Determination Date (a
"Treasury Rate Interest Determination Date") as the rate from the auction held
on such Treasury Rate Interest Determination Date (the "Auction") of direct
obligations of the United States ("Treasury Bills") having the Index Maturity
specified in the applicable Floating Interest Rate Notice under the caption
"INVESTMENT RATE", on the display on Bridge Telerate, Inc. (or any successor
service) on page 56 (or any other page as may replace such page on such service)
("Telerate Page 56") or page 57 (or any other page as may replace such page on
such service) ("Telerate Page 57") or, if not so published by 3:00 P.M., New
York City time, on the related Calculation Date, the Bond Equivalent Yield (as
defined below) of the rate for such Treasury Bills as published in H.15 Daily
Update, or such other recognized electronic source used for the purpose of
displaying such rate, under the caption "U.S. Government Securities/Treasury
Bills/Auction High" or, if not so published by 3:00 P.M., New York City time, on
the related Calculation Date, the Bond Equivalent Yield of the auction rate of
such Treasury Bills as announced by the United States Department of the
Treasury. In the event that the auction rate of Treasury Bills having the Index
Maturity in the applicable Floating Interest Rate Notice is not so announced by
the United States Department of the Treasury, or if no such Auction is held,
then the Treasury Rate will be the Bond Equivalent Yield of the rate on such
Treasury Rate Interest Determination Date of Treasury Bills having the Index
Maturity specified in the applicable Floating Interest Rate Notice as published
in H.15(519) under the caption "U.S. Government Securities/Treasury
Bills/Secondary Market" or, if not yet published by 3:00 P.M., New York City
time, on the related Calculation Date, the rate on such Treasury Rate Interest
Determination Date of such Treasury Bills as published in H.15 Daily Update, or
such other recognized electronic source used for the purpose of displaying such
rate, under the caption "U.S. Government Securities/Treasury Bills/Secondary
Market." If such rate is not yet

                                      A-20
<PAGE>   64

published in H.15(519), H.15 Daily Update or another recognized electronic
source, then the Treasury Rate will be calculated by the Calculation Agent and
will be the Bond Equivalent Yield of the arithmetic mean of the secondary market
bid rates, as of approximately 3:30 P.M., New York City time, on such Treasury
Rate Interest Determination Date, of three primary United States government
securities dealers (which may include the Remarketing Agent or its affiliates)
selected by the Calculation Agent, after consultation with the Company, for the
issue of Treasury Bills with a remaining maturity closest to the Index Maturity
specified in the applicable Floating Interest Rate Notice; provided, however,
that if the dealers so selected by the Calculation Agent are not quoting as
mentioned in this sentence, the Treasury Rate determined as of such Treasury
Rate Interest Determination Date will be the Treasury Rate in effect on such
Treasury Rate Interest Determination Date.

         "Bond Equivalent Yield" means a yield (expressed as a percentage)
calculated in accordance with the following formula:

                  Bond Equivalent Yield =       D x N
                                               ------      X   100
                                            360 - (D x M)

                  where "D" refers to the applicable per annum rate for Treasury
Bills quoted on a bank discount basis, "N" refers to 365 or 366, as the case may
be, and "M" refers to the actual number of days in the applicable Interest Reset
Period.

         (d)      Failure of Remarketing Agent or Agents to Announce Interest.
In the event that (i) the Remarketing Agent has been removed or has resigned and
no successor has been appointed, or (ii) the Remarketing Agent has failed to
announce the appropriate interest rate, Spread, if any, or Spread Multiplier, if
any, as the case may be, on an Interest Rate Adjustment Date for whatever
reason, or (iii) the appropriate interest rate, Spread, if any, or Spread
Multiplier, if any, as the case may be, or Interest Rate Period cannot be
determined for whatever reason, then this Note shall be automatically converted
to a Weekly Rate Period, and the rate of interest hereon shall be equal to the
Special Interest Rate.

         (e)      Notice of Interest Rate, Binding Effect. On each Interest Rate
Adjustment Date of this Note, the Remarketing Agent or the SPURS Agent, as the
case may be, will notify the Company and the Trustee of the interest rate,
Spread, if any, or Spread Multiplier, if any, as the case may be, to be borne by
this Note for the following Interest Rate Period. After such Interest Rate
Adjustment Date, any beneficial owner of this Note may contact the Trustee or
the Remarketing Agent in order to be advised of the applicable interest rate
and, in the case of a floating interest rate, the Spread (if any) and the Spread
Multiplier (if any). Immediately upon receipt of such notice, the Trustee will
transmit such information to DTC in accordance with DTC's procedures as in
effect from time to time and note such rate in Annex A. The Trustee shall
confirm to DTC the interest rate for the following Interest Rate Period in
accordance with DTC's procedures as in effect from time to time. No notice of
the applicable interest rate will be sent to the beneficial owner of this Note.

                                      A-21
<PAGE>   65

         The interest rate announced by the Remarketing Agent, absent manifest
error, is binding and conclusive upon the beneficial owner of this Note, the
Company and the Trustee.

         (f)      Conversion. This Note may be converted at the option of the
Company to the Commercial Paper Term Mode, Long Term Rate Mode or SPURS Mode on
any Interest Rate Adjustment Date for this Note in accordance with the
procedures set forth in the Indenture, and will be subject to mandatory tender
by the beneficial owner hereof as described herein on such Interest Rate
Adjustment Date. The beneficial owner of this Note will be deemed to have
tendered such Note as of the Interest Rate Adjustment Date upon which such
conversion occurs and will not be entitled to further accrual of interest on
this Note after such date.

                                     TENDER

         This Note will be automatically tendered for purchase, or deemed
tendered for purchase by the beneficial owner hereof, on each Interest Rate
Adjustment Date relating hereto. Notes will be purchased on such Interest Rate
Adjustment Date in accordance with the procedures set forth in "Remarketing and
Settlement" or, as the case may be, "SPURS Mode" below.

                           REMARKETING AND SETTLEMENT

         Interest Rate Adjustment Date; Determination of Interest Rate. By 11:00
a.m., New York City time on each Interest Rate Adjustment Date for this Note,
the applicable Remarketing Agent will determine the interest rate hereon to the
nearest one hundred-thousandth (0.00001) of one percent per annum for the next
Interest Rate Period in the case of a fixed interest rate, and the Spread (if
any) and Spread Multiplier (if any) in the case of a floating interest rate;
provided, that between 11:00 a.m., New York City time and 11:50 a.m., New York
City time, the Remarketing Agent and the Standby Remarketing Agent(s), if any,
shall use their reasonable efforts to determine the interest rate for this Note
if it is not successfully remarketed as of the applicable deadline specified in
this paragraph. In determining the applicable interest rate for this Note and
other terms, the Remarketing Agent will, after taking into account market
conditions as reflected in the prevailing yields on fixed and variable rate
taxable debt securities, (i) consider the principal amount of all Notes tendered
or to be tendered on such date and the principal amount of such Notes
prospective purchasers are or may be willing to purchase and (ii) contact, by
telephone or otherwise, prospective purchasers and ascertain the interest rates
or the Spread or Spread Multiplier therefor at which they would be willing to
hold or purchase this Note.

         Notification of Results; Settlement. By 12:30 p.m., New York City time,
on each Interest Rate Adjustment Date for this Note, the applicable Remarketing
Agent will notify the Company and the Trustee in writing (which may include
facsimile or other electronic transmission), of (i) the interest rate or, in the
case of a floating interest rate, the initial interest rate, the Spread and
Spread Multiplier and the Initial Interest Reset Date, applicable to this Note
for the next Interest Rate Period, (ii) the Interest Rate Adjustment Date, (iii)
the Interest Payment Dates, if this Note will then be in the Commercial Paper
Term Mode (if other than the Interest Rate Adjustment Date), the Long Term Rate
Mode or the SPURS Mode, (iv) the optional redemption terms, if

                                      A-22
<PAGE>   66

any, and early remarketing terms, if any, in the case of remarketing into a Long
Term Rate Period, (v) the aggregate principal amount of all Notes tendered for
remarketing on such date, and (vi) the aggregate principal amount of such
tendered Notes which such Remarketing Agent was able to remarket, at a price
equal to 100% of the principal amount thereof plus accrued interest, if any.
Immediately after receiving such notice and, in any case, not later than 1:30
p.m., New York City time, the Trustee will transmit such information and any
other settlement information required by DTC to DTC in accordance with DTC's
procedures as in effect from time to time.

         By telephone at approximately 1:00 p.m., New York City time, on such
Interest Rate Adjustment Date, the applicable Remarketing Agent will advise the
purchaser of this Note (or the DTC participant of each such purchaser who it is
expected in turn will advise such purchaser) of the principal amount of such
Notes that such purchaser is to purchase.

         The purchaser of this Note in a remarketing will be required to give
instructions to its DTC participant to pay the purchase price therefor in same
day funds to the applicable Remarketing Agent against delivery of the principal
amount of this Note by book-entry through DTC by 3:00 p.m., New York City time,
on the Interest Rate Adjustment Date.

         When tendered, or deemed tendered, this Note will be automatically
delivered to the account of the Trustee (or such other account meeting the
requirements of DTC's procedures as in effect from time to time), by book-entry
through DTC against payment of the purchase price or redemption price herefor,
on the Interest Rate Adjustment Date relating hereto.

         The applicable Remarketing Agent will make, or cause the Trustee to
make, payment to the DTC participant of the tendering beneficial owner hereof
subject to a remarketing, by book-entry through DTC by the close of business on
the related Interest Rate Adjustment Date against delivery through DTC of the
beneficial owner's tendered Note, of the purchase price for this Note. If this
Note was purchased pursuant to a Special Mandatory Purchase, subject to receipt
of funds from the Company or the Liquidity Provider (if any), as the case may
be, the Trustee will make such payment of the purchase price for this Note plus
accrued interest, if any, to such date.

         The transactions described above for a remarketing of this Note will be
executed on each Interest Rate Adjustment Date for this Note through DTC in
accordance with the procedures of DTC, and the accounts of the respective DTC
participants will be debited and credited and this Note will be delivered by
book-entry as necessary to effect the purchases and sales hereof, in each case
as determined in the related remarketing.

         Except as otherwise set forth below, the purchase price for this Note
to the tendering beneficial owner shall be paid solely out of the proceeds
received from a purchaser of this Note in such remarketing, and neither the
Trustee, the applicable Remarketing Agent, any Standby Remarketing Agent(s) nor
the Company (except as set forth below) will be obligated to provide funds to
make payment upon any beneficial owner's tender of this Note in a remarketing.

                                      A-23
<PAGE>   67

         The tender and settlement procedures described above, including
provisions for payment by purchasers of this Note or for payment to the selling
beneficial owners of this Note, may be modified to the extent required by DTC.
In addition, each Remarketing Agent may, without the consent of the Holders of
the Notes, modify the tender and settlement procedures set forth above in order
to facilitate the settlement and remarketing process.

         As long as DTC's nominee holds the certificates representing this Note
in the book-entry system of DTC, no certificates for this Note will be delivered
by any selling beneficial owner to reflect any transfer of this Note effected in
any remarketing.

         Failed Remarketing. If this Note is not successfully remarketed, this
Note shall be subject to Special Mandatory Purchase by the Company (a "Special
Mandatory Purchase"). The obligation of the Company to effect a Special
Mandatory Purchase can be satisfied either directly by the Company or through a
Liquidity Provider. By 12:00 o'clock noon, New York City time, on any Interest
Rate Adjustment Date for this Note, the applicable Remarketing Agent will notify
the Liquidity Provider, if any, the Trustee and the Company by telephone or
facsimile, confirmed in writing, if it, or the Standby Remarketing Agent or
Agents were unable to remarket all or a portion of the principal amount of this
Note on such date. In the event that the Company has entered into a Standby Note
Purchase Agreement which is in effect on such date, such notice will constitute
a demand for the benefit of the Company to the Liquidity Provider, if any, to
purchase this Note at a price equal to the outstanding principal amount hereof
pursuant to the terms of such Standby Note Purchase Agreement. If a Standby Note
Purchase Agreement is not in effect on such date, or if the Liquidity Provider
fails to advance funds under the Standby Note Purchase Agreement, the Company
hereby agrees to purchase this Note. In each case, the Company will pay all
accrued and unpaid interest, if any, on this Note to such Interest Rate
Adjustment Date. Payment of the principal amount of this Note by the Company or
the Liquidity Provider, as the case may be, and payment of accrued and unpaid
interest, if any, by the Company, shall be made by deposit of same-day funds in
the account of the Trustee (or such other account meeting the requirements of
DTC's procedures as in effect from time to time) irrevocably in trust for the
benefit of the beneficial owners of this Note subject to Special Mandatory
Purchase by 3:00 p.m., New York City time, on the related Interest Rate
Adjustment Date.

                              TRANSFER OR EXCHANGE

         As provided in the Indenture and subject to certain limitations set
forth therein and herein, the transfer of this Note is registrable in the
Security Register, 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
premium, if any, 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 of transfer in the form attached hereto, the
Company and the Security Registrar or any transfer agent duly executed, by the
registered owner hereof or his attorney duly authorized in writing, and
thereupon one or more new Notes of this series and of like tenor, of

                                      A-24
<PAGE>   68

authorized denominations and for the same aggregate principal amount will be
issued to the designated transferee or transferees.

         The Notes are issuable only in fully registered form in denominations
of $100,000 and integral multiples of $1,000 in excess thereof. As provided in
the Indenture and subject to certain limitations set forth therein and herein,
this Note is exchangeable for a like aggregate principal amount of Notes of this
series and of like tenor of any authorized denomination, as requested by the
registered owner surrendering the same.

         No service charge shall be made for any registration of transfer or
exchange of this Note, but, subject to certain limitations set forth in the
Indenture, the Company may require payment of a sum sufficient to cover any tax
or other governmental charge payable in connection therewith.

         Subject to the terms of the Indenture, prior to due presentment of this
Note for registration of transfer, the Company, the Trustee and any agent of the
Company or the Trustee may treat the Person in whose name this Note is
registered as the owner hereof for all purposes, whether or not this Note is
overdue, and neither the Company, the Trustee nor any such agent shall be
affected by notice to the contrary.

                           REDEMPTION AND ACCELERATION

         Special Mandatory Purchase. If by 12:00 o'clock noon, New York City
time, on any Interest Rate Adjustment Date for this Note, the applicable
Remarketing Agent and the applicable Standby Remarketing Agent(s) have not
remarketed this Note, this Note shall be subject to Special Mandatory Purchase.
Either the Company or, subject to the terms and conditions of a Standby Note
Purchase Agreement, if any, which may be in effect on such date, the Liquidity
Provider (if any), will deposit same-day funds in the account of the Trustee (or
such other account meeting the requirements of DTC's procedures as in effect
from time to time) irrevocably in trust for the benefit of the beneficial owners
of this Note subject to Special Mandatory Purchase by 3:00 p.m., New York City
time, on such Interest Rate Adjustment Date. Such funds shall be in an amount
sufficient to pay the aggregate purchase price of this Note, equal to 100% of
the principal amount thereof. In the event a Standby Note Purchase Agreement is
in effect but the Liquidity Provider shall fail to advance funds for whatever
reason thereunder, the Company hereby agrees to purchase this Note on such
Interest Rate Adjustment Date. The Company has agreed in the Indenture to pay
the accrued interest, if any, on this Note by depositing sufficient same-day
funds therefor with the Trustee (or such other account meeting the requirements
of DTC's procedures as in effect from time to time) by 3:00 p.m., New York City
time, on such Interest Rate Adjustment Date.

         Failure by the Company to purchase this Note pursuant to a Special
Mandatory Purchase in the manner provided in this Note will constitute an Event
of Default under the Indenture in which event the date of such failure shall
constitute a date of Maturity for this Note and the principal hereof may be
declared due and payable in the manner and with the effect provided in the
Indenture. Following such failure to pay pursuant to a Special Mandatory
Purchase, this Note will bear interest at the Special Interest Rate as provided
above under "Interest."

                                      A-25

         Optional Redemption on any Interest Rate Adjustment Date. This Note is
subject to Optional Redemption, at the direction of the Company and without
notice to the Holders, on any Interest Rate Adjustment Date relating hereto, in
whole or in part, at a redemption price equal to 100% of the principal amount to
be redeemed plus accrued and unpaid interest to the date set for redemption (the
"Redemption Date").

         Optional Redemption While This Note is in the Long Term Rate Mode. So
long as this Note bears interest in the Long Term Rate Mode, this Note is
subject to Optional Redemption at the written direction of the Company if so
specified at the time of conversion to or within such Long Term Rate Mode (a)
commencing on the Commencement Date, if any, specified in Annex A, in whole or
in part at any time, at the applicable redemption prices for any Redemption Date
(dates inclusive) (i) from the Commencement Date to but not including the first
anniversary of the Commencement Date, (ii) from the first anniversary of the
Commencement Date to but not including the second anniversary of the
Commencement Date, and (iii) from the second anniversary of the Commencement
Date and thereafter (expressed as percentage of the principal amount so
redeemed) set forth in Annex A, plus accrued interest to the Redemption Date or
(b) otherwise as set forth in Annex A.

         Notice of redemption shall be given by mail to the registered owner of
this Note, 30 days prior to the Redemption Date, all as provided in the
Indenture. As provided in the Indenture, notice of redemption as aforesaid may
state that such redemption shall be conditioned upon the receipt by the Trustee
of the redemption monies on or before the date fixed for such redemption; a
notice of redemption so conditioned shall be of no force or effect if such money
is not so received.

         The Company shall not be required to (a) issue, register the transfer
of or exchange Notes of this series during a period beginning at the opening of
business 15 days before any selection of Notes of this series to be redeemed and
ending at the close of business on the day of the mailing of the relevant notice
of redemption or (b) register the transfer of or exchange any Notes selected for
redemption, in whole or in part, except the unredeemed portion of any Note being
redeemed in part.

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

         Allocation. Except in the case of a Special Mandatory Purchase, if this
Note is to be redeemed in part, DTC, after receiving notice of redemption
specifying the aggregate principal amount of this Note to be so redeemed, will
determine by lot (or otherwise in accordance with the procedures of DTC) the
principal amount of this Note to be redeemed from the account of each DTC
participant. After making its determination as described above, DTC will give
notice of such determination to each DTC participant from whose account this
Note is to be redeemed. Each such DTC participant, upon receipt of such notice,
will in turn determine the principal amount of this Note to be redeemed from the
accounts of the beneficial owners of this Note for

                                      A-26
<PAGE>   70

which it serves as DTC participant, and give notice of such determination to the
Remarketing Agent.

         Acceleration. If any Event of Default with respect to the Notes shall
occur and be continuing, the principal of the Notes may be declared due and
payable in the manner and with the effect provided in the Indenture.

                                   SPURS MODE

         Notwithstanding anything herein to the contrary, the provisions of this
section shall apply to this Note upon conversion to the SPURS Mode, and shall
supersede any conflicting provisions of general applicability contained
elsewhere herein, during the period from, and including, the Interest Rate
Adjustment Date beginning a SPURS Rate Period to, but excluding, the next
succeeding Interest Rate Adjustment Date (or if the SPURS Agent does not elect
to purchase this Note on the SPURS Remarketing Date designated for such SPURS
Mode or if after electing to so purchase this Note the SPURS Agent fails for any
reason to so purchase this Note, to the SPURS Remarketing Date).

         (a) Interest To SPURS Remarketing Date. The Interest Rate Period for
this Note in the SPURS Mode will be established by the Company (as described in
"Interest Rate" above) as a period of more than 364 days and not exceeding the
remaining term to the Stated Maturity of this Note; provided, however, that such
Interest Rate Period must end on the day prior to an Interest Payment Date for
this Note. The SPURS Rate Period shall consist of the period from and including
the Interest Rate Adjustment Date commencing such Interest Rate Period to and
excluding the date (the "SPURS Remarketing Date") designated at such time by the
SPURS Agent after consultation with the Company and set forth in Annex A hereto.
The interest rate and, in the case of a floating interest rate, the Spread, if
any, and the Spread Multiplier, if any, to the SPURS Remarketing Date for this
Note in the SPURS Mode will be determined not later than 11:50 a.m., New York
City time, on the Interest Rate Adjustment Date for this Note, which for the
SPURS Mode is the first day of the SPURS Rate Period for this Note. Such
interest rate will be the minimum rate of interest and, in the case of a
floating interest rate, Spread (if any) and Spread Multiplier (if any) necessary
in the judgment of such SPURS Agent to produce a par bid in the secondary market
for this Note on the date the interest is established. The designated SPURS
Remarketing Date shall be an Interest Payment Date within such Interest Rate
Period.

         (b) Mandatory Tender. Provided that the SPURS Agent gives notice to the
Company and the Trustee on a Business Day not later than ten (10) days prior to
the SPURS Remarketing Date of its intention to purchase this Note for
remarketing (the "Notification Date"), this Note shall be automatically
tendered, or deemed tendered, to the SPURS Agent for purchase on the SPURS
Remarketing Date, except in the circumstances described in "Redemption" below,
for 100% of the principal amount hereof. Upon tender, the SPURS Agent may
remarket this Note for its own account at varying prices to be determined by the
SPURS Agent at the time of such sale. From, and including, the SPURS Remarketing
Date to, but excluding, the next succeeding Interest Rate Adjustment Date, this
Note shall bear interest at the SPURS Interest Rate. If the

                                      A-27
<PAGE>   71

SPURS Agent elects to remarket this Note, the obligation of the SPURS Agent to
purchase this Note on the SPURS Remarketing Date is subject to, among other
things, the conditions that, since the Notification Date, no material adverse
change in the condition of the Company and its subsidiaries, considered as one
enterprise, shall have occurred and that no Event of Default (as defined in the
Indenture), or any event which, with the giving of notice or passage of time, or
both, would constitute an Event of Default, with respect to this Note shall have
occurred and be continuing.

         (c) Remarketing; Establishing the SPURS Interest Rate. Subject to the
SPURS Agent's election to remarket this Note, the SPURS Interest Rate shall be
determined by the SPURS Agent by 3:30 p.m., New York City time, on the third
Business Day immediately preceding the SPURS Remarketing Date (the
"Determination Date") to the nearest one hundred-thousandth (0.00001) of one
percent per annum, and shall be equal to the Base Rate established by the SPURS
Agent, after consultation with the Company, at or prior to the commencement of
the SPURS Mode (the "Base Rate") plus the Applicable Spread, which shall be
based on the Dollar Price of this Note as of the SPURS Remarketing Date.

         (d) Notification of Results; Settlement. Provided the SPURS Agent has
previously notified the Company and the Trustee on the Notification Date of its
intention to purchase this Note on the SPURS Remarketing Date, the SPURS Agent
shall notify the Company, the Trustee and DTC by telephone, confirmed in
writing, by 4:00 p.m., New York City time, on the Determination Date, of the
SPURS Interest Rate, and this Note shall be automatically delivered to the
account of the Trustee, by book-entry through DTC pending payment of the
purchase price therefor, on the SPURS Remarketing Date.

         In the event that the SPURS Agent purchases this Note on the SPURS
Remarketing Date, the SPURS Agent shall make or cause the Trustee to make
payment to the DTC participant of each tendering beneficial owner hereof, by
book-entry through DTC by the close of business on the SPURS Remarketing Date
against delivery through DTC of such beneficial owner's interest herein, of 100%
of the principal amount for this Note. If the SPURS Agent does not purchase this
Note on the SPURS Remarketing Date, the Company may attempt to convert this Note
to a new Interest Rate Mode; the interest rate will be determined as provided
above in "Interest Rate" and settlement will be effected as described under
"Remarketing and Settlement" above. In any case, the Company shall make or cause
the Trustee to make payment of interest to each beneficial owner of this Note
due on the SPURS Remarketing Date by book-entry through DTC by the close of
business on the SPURS Remarketing Date.

         The transactions set forth above shall be executed on the SPURS
Remarketing Date through DTC in accordance with the procedures of DTC, and the
accounts of the respective DTC participants shall be debited and credited and
this Note shall be delivered by book-entry as necessary to effect the purchases
and sales thereof.

                                      A-28
<PAGE>   72

         Transactions involving the sale and purchase of Notes remarketed by the
SPURS Agent on and after the SPURS Remarketing Date will settle in immediately
available funds through DTC's Same-Day Funds Settlement System.

         The tender and settlement procedures set forth above, including
provisions for payment by purchasers of this Note in the remarketing or for
payment to selling beneficial owners of this Note, may be modified to the extent
required by DTC or to the extent required to facilitate the tender and
remarketing of this Note in certificated form, if the book-entry system is no
longer available for this Note at the time of the remarketing. In addition, the
SPURS Agent may, without the consent of the Holders of the Notes, modify the
settlement procedures set forth above in order to facilitate the tender and
settlement process.

         As long as DTC's nominee holds the certificates representing this Note
in the book-entry system of DTC, no certificates for this Note shall be
delivered by any selling beneficial owner to reflect any transfer of such Notes
effected in the remarketing.

         (e) Conversion or Redemption Following Election by the SPURS Agent to
Remarket. If the SPURS Agent elects to remarket this Note on the SPURS
Remarketing Date, this Note will be subject to a mandatory tender to the SPURS
Agent for remarketing on such date, in each case subject to the conditions set
forth above and to the Company's right to either convert this Note to a new
Interest Rate Mode on the SPURS Remarketing Date or to redeem this Note from the
SPURS Agent, in each case as described in the next sentence. The Company will
notify the SPURS Agent and the Trustee, not later than the Business Day
immediately preceding the Determination Date, if the Company irrevocably elects
to exercise its right to either convert the Notes to a new Interest Rate Mode,
or to redeem the Notes, in whole but not in part, from the SPURS Agent at the
Optional Redemption Price, in each case on the SPURS Remarketing Date.

         In the event that the Company irrevocably elects to convert this Note
to a new Interest Rate Mode, then as of the SPURS Remarketing Date the Notes
will cease to be in the SPURS Mode, the SPURS Remarketing Date will constitute
an Interest Rate Adjustment Date, and this Note will be subject to remarketing
on such date by a Remarketing Agent appointed by the Company in the Commercial
Paper Term Mode or the Long Term Rate Mode or a new SPURS Mode established by
the Company in accordance with the procedures set forth herein; provided that in
such case, the notice period required for conversion shall be the period
commencing the Business Day immediately preceding the Determination Date. In
such case, the Company shall pay to the SPURS Agent the excess of the Dollar
Price of this Note over 100% of the principal amount of this Note in same-day
funds by wire transfer to an account designated by the SPURS Agent on the SPURS
Remarketing Date.

         In the event that the Company irrevocably elects to redeem this Note,
the "Optional Redemption Price" shall be the greater of (i) 100% of the
principal amount of this Note and (ii) the Dollar Price, plus in either case
accrued and unpaid interest from the SPURS Remarketing Date on the principal
amount being redeemed to the date of redemption. If the

                                      A-29
<PAGE>   73

Company elects to redeem this Note, it shall pay the redemption price therefor
in same-day funds by wire transfer to an account designated by the SPURS Agent
on the SPURS Remarketing Date.

         If notice has been given as provided in the Indenture and funds for the
redemption of any Notes called for redemption shall have been made available on
the redemption date referred to in such notice, this Note shall cease to bear
interest on the date fixed for such redemption specified in such notice and the
only right of the SPURS Agent from and after the redemption date shall be to
receive payment of the Optional Redemption Price upon surrender of this Note in
accordance with such notice.

                                OTHER PROVISIONS

following an Event of Default, and the principal of this Note may not be

the Trustee.

                             STATEMENT OF INSURANCE

         The MBIA Insurance Corporation (the "Insurer") has issued a policy
containing the following provisions, such policy being on file at the office of
The Bank of New York, New York, New York.

MBIA Insurance Corporation (the "Insurer"), in consideration of the payment of
the premium and subject to the terms of this policy, hereby unconditionally and
irrevocably guarantees to any owner, as hereinafter defined, of the following
described obligations, the full and complete payment required to be made by or
on behalf of the Issuer to The Bank of New York or its successor (the "Paying
Agent") of an amount equal to (i) the principal of the Obligations (as that term
is defined below) on the initial mandatory tender date of June 15, 2003 and
interest on the Obligations as such payments become due on and prior to such
initial mandatory tender date but shall not be so paid (except that in the event
of any acceleration of the due date of such principal by reason of mandatory or
optional redemption, or acceleration resulting from default or otherwise, the
payments guaranteed hereby shall be made in such amounts and at such times as
such payments of principal would have been due had there not been any such
acceleration); and (ii) the reimbursement of any such payment which is
subsequently recovered from any owner pursuant to a final judgment by a court of
competent jurisdiction that such payment constitutes an avoidable preference to
such owner within the meaning of any applicable bankruptcy law. The amounts
referred to in clauses (i) and (ii) of the preceding sentence shall be referred
to herein collectively as the "Insured Amounts." "Obligations" shall mean:

                                  $100,000,000
                      DTE Energy Company Remarketed Notes,
 Series A due 2038 through the Initial Interest Rate Adjustment Date of June 15,
 2003

Upon receipt of telephonic or telegraphic notice, such notice subsequently
confirmed in writing by registered or certified mail, or upon receipt of written
notice by registered or certified mail, by the Insurer from the Paying Agent or
any owner of an Obligation the payment of an Insured Amount for which is then
due, that such required payment has not been made, the Insurer on the due date
of such payment or within one business day after receipt of notice of such
nonpayment, whichever is later, will make a deposit of funds, in an account with
State Street Bank and Trust Company, N.A., in New York, New York, or its
successor, sufficient for the payment of any such Insured Amounts which are then
due. Upon presentment and surrender of such Obligations or presentment of such
other proof of ownership of the Obligations, together with any appropriate
instruments of assignment to evidence the assignment of the Insured Amounts due
on the Obligations as are paid by the Insurer, and appropriate instruments to
effect the appointment of the Insurer as agent for such owners of the
Obligations in any legal proceeding related to payment of Insured Amounts on the
Obligations, such instruments being in a form satisfactory to State Street Bank
and Trust Company, N.A., State Street Bank and Trust Company, N.A. shall
disburse to such owners, or the Paying Agent payment of the Insured Amounts due
on such Obligations, less any amount held by the Paying Agent for the payment of

                                      A-39
<PAGE>   83

such Insured Amounts and legally available therefor. This policy does not
insure against loss of any prepayment premium which may at any time be payable
with respect to any Obligation.

As used herein, the term "owner" shall mean the registered owner of any
Obligation as indicated in the books maintained by the Paying Agent, the Issuer,
or any designee of the Issuer for such purpose. The term owner shall not include
the Issuer or any party whose agreement with the Issuer constitutes the
underlying security for the Obligations.

Any service of process on the Insurer may be made to the Insurer at its offices
located at 113 King Street, Armonk, New York 10504 and such service of process
shall be valid and binding.

This policy is non-cancellable for any reason. The premium on this policy is not
refundable for any reason including the payment prior to maturity of the
Obligations.

This policy is not covered by the Property/Casualty Insurance Security Fund
specified in Article 76 of the New York Insurance Law.
