OTHER/ADDITIONAL TERMS:                            ADDENDUM ATTACHED:

         WELLS FARGO & COMPANY, a corporation duly organized and existing under
the laws of the State of Delaware (hereinafter called the "Company", which term
includes any successor corporation under the Indenture hereinafter referred to),
for value received, hereby promises to pay to __________________, or registered
assigns, the principal sum of _______________________ Dollars ($______________)
on the Stated Maturity Date shown above (except to the extent redeemed or repaid
prior to such date) and to pay interest, if any, on the principal amount hereof
at the Interest Rate shown above (computed on the basis of a 360-day year of
twelve 30-day months), semi-annually on each Interest Payment Date set forth
above from and after the date of this Security and at Maturity until payment of
the principal amount hereof has been made or duly provided for. Unless this
Security is a Security which has been issued upon transfer of, in exchange for,
or in replacement of, a Predecessor Security, interest on this Security shall
accrue from the Original Issue Date indicated above. If this Security has been
issued upon transfer of, in exchange for, or in replacement of, a Predecessor
Security, interest on this Security shall accrue from the last Interest Payment
Date to which interest was paid on such Predecessor Security or, if no interest
was paid on such Predecessor Security, from the Original Issue Date indicated
above. The first payment of interest on a Security originally issued and dated
between a Regular Record Date specified above and an Interest Payment Date will
be due and payable on the Interest Payment Date following the next succeeding
Regular Record Date to the registered owner on such next succeeding Regular
Record Date. Subject to certain exceptions provided in the Indenture referred to
herein below, the interest so payable on any Interest Payment Date will be paid
to the Person in whose name this Security is registered at the close of business
on the Regular Record Date (whether or not a Business Day) next preceding such
Interest Payment Date, and interest payable upon Maturity will be paid to the
person to whom principal is payable.

         Notwithstanding the foregoing, if an Addendum is attached hereto or
"Other/Additional Terms" apply to this Security as specified above, this
Security shall be subject to the terms set forth in such Addendum or such
"Other/Additional Terms."

         The principal (and premium, if any) and interest on this Security is
payable by the Company in the Specified Currency specified above.

         Any interest not punctually paid or duly provided for will forthwith
cease to be payable to the Holder on such Regular Record Date and may either be
paid to the Person in whose name this Security (or one or more Predecessor
Securities) is registered at the close of business on a Special Record Date for
the payment of such Defaulted Interest to be fixed by the Trustee, notice
whereof shall be given to Holders of Securities of this series not less than 10
days prior to such Special Record Date, or be paid at any time in any other
lawful manner not inconsistent

                                       2

with the requirements of any securities exchange on which the Securities of this
series may be listed, and upon such notice as may be required by such exchange,
all as more fully provided in the Indenture.

         Until this Security is paid in full or payment therefor in full is duly
provided for, the Company will at all times maintain a Paying Agent (which
Paying Agent may be the Trustee) in New York City or Minneapolis, Minnesota. The
Company has initially appointed Wells Fargo Bank Minnesota, National Association
as the Paying Agent at its corporate trust offices at Minneapolis, Minnesota.

         If this Security is a Global Security: Payments of principal and any
premium and interest on this Security will be made to DTC or its nominee, as
Holder of this Security, by wire transfer of immediately available funds.

         If this Security is not a Global Security: Payment of interest on this
Security (other than payments of interest at Maturity) will be made by check
mailed to the Person entitled thereto at such Person's last address as it
appears in the Security Register or, in the case of a Holder of $50,000,000 or
more in aggregate principal amount of Securities of this series having the same
Interest Payment Date, by wire transfer of immediately available funds to such
account as may have been designated by such Holder. Any such designation for
wire transfer purposes shall be made by filing the appropriate information with
the Paying Agent at its corporate trust office not later than 10 calendar days
prior to the applicable Interest Payment Date and, unless revoked by written
notice to the Paying Agent received by the Paying Agent on or prior to the
Regular Record Date immediately preceding the applicable Interest Payment Date,
shall remain in effect with respect to any further payments with respect to this
Security payable to such Holder. Payment of principal of and interest, if any,
on this Security at Maturity will be made against presentation of this Security
at the office or agency of the Company maintained for that purpose in New York
City or Minneapolis, Minnesota.

         The Company will pay any administrative costs imposed by banks on
payors in making payments on this Security in immediately available funds and
the Holder of this Security will pay any administrative costs imposed by banks
on payees in connection with such payments. Any tax, assessment or governmental
charge imposed upon payments on this Security will be borne by the Holder of
this Security.

         Any payment on this Security due on any day which is not a Business Day
need not be made on such day, but may be made on the next succeeding Business
Day with the same force and effect as if made on the due date and no additional
interest shall accrue on the amount so payable for the period from and after
such date. For purposes of this Security, "Business Day" means any day other
than a Saturday, Sunday or a legal holiday or a day on which banking
institutions are authorized or required by law or regulation to close in New
York City or Minneapolis, Minnesota.

                  DUE NINE MONTHS OR MORE FROM DATE OF ISSUE

General

         This Security is one of a duly authorized issue of securities of the
Company (herein called the "Securities"), issued and to be issued in one or more
series under an indenture dated as of August 30, 1999, as amended or
supplemented from time to time (herein called the "Indenture"), between the
Company and Bank One Trust Company, N.A. (successor in interest to The First
National Bank of Chicago), as Trustee (herein called the "Trustee", which term
includes any successor trustee under the Indenture), to which Indenture and all
indentures supplemental thereto, reference is hereby made for a statement of the
respective rights, limitations of rights, duties and immunities thereunder of
the Company, the Trustee and the Holders of the Securities, and of the terms
upon which the Securities are, and are to be, authenticated and delivered. This
Security is one of the series of the Securities designated as Subordinated
Medium-Term Notes, Series D, of the Company, which series is limited to an
aggregate principal amount of $10,000,000,000 or the equivalent thereof in one
or more foreign or composite currencies minus the aggregate principal amount of
the Company's Medium-Term Notes, Series C which may be issued from time to time.
The Securities of this series may mature at different times, bear interest, if
any, at different rates, be redeemable at different times or not at all, be
repayable at the option of the Holder at different times or not at all, be
issued at an original issue discount and be denominated in different currencies.

         The Securities are issuable only in registered form without coupons and

certificated securities issued to and registered in the names of, the beneficial
owners or their nominees.

         The indebtedness evidenced by this Security is, to the extent and in
the manner set forth in the Indenture, subordinate and subject in right of
payment to the prior payment in full of the principal of and premium, if any,
and interest on all Senior Debt of the Company, and the Holder of this Security,
by accepting the same, agrees to and shall be bound by the provisions of the
Indenture with respect thereto.

Events of Default

         If an Event of Default, as defined in the Indenture, with respect to
Securities of this series shall occur and be continuing, the principal of the
Securities of this series may be declared due and payable in the manner and with
the effect provided in the Indenture.

Modification and Waivers; Obligation of the Company Absolute

         The Indenture permits, with certain exceptions as therein provided, the
amendment thereof and the modification of the rights and obligations of the
Company and the rights of the Holders of the Securities of each series to be
affected under the Indenture at any time by the Company and the Trustee with the
consent of the Holders of a majority in principal amount of the Securities at
the time Outstanding of all series to be affected, acting together as a class.
The Indenture also contains provisions permitting the Holders of a majority in
principal amount of the Securities of all series at the time Outstanding
affected by certain provisions of the Indenture, acting together as a class, on
behalf of the Holders of all Securities of such series, to waive compliance by
the Company with those provisions of the Indenture. Certain past defaults under
the Indenture and their consequences may be waived under the Indenture by the
Holders of a majority in principal amount of the Securities of each series at
the time Outstanding, on behalf of the Holders of all Securities of such series.
Any such consent or waiver by the Holder of this Security shall be conclusive
and binding upon such Holder and upon all future Holders of this Security and of
any Security issued upon the registration of transfer hereof or in exchange
herefor or in lieu hereof, whether or not notation of such consent or waiver is
made upon this Security.

         Subject to the rights of holders of Senior Debt of the Company set
forth in this Security and the Indenture referred to above, no reference herein
to the Indenture and no provision of this Security or of the Indenture shall
alter or impair the obligation of the Company, which is absolute and
unconditional, to pay the principal of and interest on this Security at the
times, place and rate, and in the coin or currency, herein prescribed, except
that in the event the Company deposits money or Eligible Instruments as provided
in Section 401 or 403 of the Indenture, such payments will be made only from
proceeds of such money or Eligible Instruments.

         The Indenture contains provisions for defeasance at any time of (a) the
entire indebtedness on this Security and (b) certain restrictive covenants and
certain Events of Default, upon compliance by the Company with certain

</TABLE>

     WELLS FARGO & COMPANY, a corporation duly organized and existing under the
laws of the State of Delaware (herein called the "Company", which term includes
any successor corporation under the Indenture hereinafter referred to), for
value received, hereby promises to pay to ______________________________, or
registered assigns, the principal sum of __________________________________
Dollars ($_____________) on the Stated Maturity Date shown above (except to the
extent redeemed or repaid prior to such date) and to pay interest, if any, on
the Interest Payment Dates specified above, commencing with the first Interest
Payment Date specified above following the Original Issue Date specified above,
and at Maturity, on the principal amount hereof, at a rate per annum equal to
the Initial Interest Rate specified above until the Initial Interest Reset Date
specified above following the Original Issue Date specified above and thereafter
at a rate per annum determined in accordance with the provisions on the reverse
hereof under the heading "Determination of CD Rate", "Determination of
Commercial Paper Rate", "Determination of

                                       2
<PAGE>

EURIBOR", "Determination of Federal Funds Rate", "Determination of LIBOR",
"Determination of Prime Rate", "Determination of Treasury Rate" or
"Determination of CMT Rate", depending upon whether the Base Rate is CD Rate,
Commercial Paper Rate, EURIBOR, Federal Funds Rate, LIBOR, Prime Rate, Treasury
Rate or CMT Rate, as specified above.

     Notwithstanding the foregoing, if an Addendum is attached hereto or
"Other/Additional Terms" apply to this Security as specified above, this
Security shall be subject to the terms set forth in such Addendum or such
"Other/Additional Terms."

     The principal (and premium, if any) and interest on this Security is
payable by the Company in the Specified Currency specified above.

     Any Interest Payment Date specified above that would fall on a day that is
not a Business Day, other than an Interest Payment Date that is also the date of
Maturity, shall be the following day that is a Business Day, except that, if the
Base Rate specified above is LIBOR or EURIBOR and such following Business Day is
in the next calendar month, such Interest Payment Date shall be the immediately
preceding day that is a Business Day. If the date of Maturity would fall on a
day that is not a Business Day, the payment of principal and any premium and
interest shall be made on the following Business Day, with the same force and
effect as if made on the due date, and no additional interest shall accrue on
the amount so payable for the period from and after such date of Maturity. For
purposes of this Security, "Business Day" means (a) any day other than a
Saturday or Sunday that is neither a legal holiday nor a day on which banking
institutions are authorized or required by law or regulation to close in New
York City or Minneapolis, Minnesota, and (b) if the Base Rate specified above is
LIBOR or EURIBOR, any day that meets the above criteria and which is also a
London Banking Day. For purposes of this Security, "London Banking Day" means
any day on which dealings in deposits in the Index Currency specified above are
transacted in the London interbank market.

     Interest payments on this Security shall be the amount of interest accrued
from and including the Original Issue Date specified above or from and including
the last date to which interest has been paid, or provided for, as the case may
be, to but excluding, the following Interest Payment Date or the date of
Maturity. If this Security has been issued upon transfer of, in exchange for, or
in replacement of, a Predecessor Security, interest on this Security shall
accrue from the last Interest Payment Date to which interest was paid on such
Predecessor Security or, if no interest was paid on such Predecessor Security,
from the Original Issue Date specified above.

     Subject to certain exceptions provided in the Indenture referred to on the
reverse hereof, the interest so payable on any Interest Payment Date shall be
paid to the Person in whose name this Security is registered at the close of
business on the Regular Record Date (whether or not a Business Day) next
preceding such Interest Payment Date, and interest payable upon the Maturity
(whether or not such date of Maturity is an Interest Payment Date)

                                       3
<PAGE>

shall be paid to the Person to whom principal is payable; provided, however,
that the first payment of interest on a Security originally issued and dated
between a Regular Record Date specified above and an Interest Payment Date shall
be due and payable on the Interest Payment Date following the next succeeding
Regular Record Date to the registered owner on such next succeeding Regular
Record Date. Unless otherwise specified on the face hereof, "Regular Record
Date" shall mean the fifteenth calendar day (whether or not a Business Day)
immediately preceding the related Interest Payment Date.

     Any interest not punctually paid or duly provided for shall forthwith cease
to be payable to the Holder on such Regular Record Date and may either be paid
to the Person in whose name this Security (or one or more Predecessor
Securities) is registered at the close of business on a Special Record Date for
the payment of such Defaulted Interest to be fixed by the Trustee, notice
whereof shall be given to Holders of Securities of this series not less than 10
days prior to such Special Record Date, or be paid at any time in any other
lawful manner not inconsistent with the requirements of any securities exchange
on which the Securities of this series may be listed, and upon such notice as
may be required by such exchange, all as more fully provided in the Indenture.

     Until this Security is paid in full or payment therefor in full is duly
provided for, the Company shall at all times maintain a Paying Agent (which
Paying Agent may be the Trustee) in New York City or Minneapolis, Minnesota. The
Company has initially appointed Wells Fargo Bank Minnesota, National Association
as the Paying Agent at its corporate trust office at Minneapolis, Minnesota.

     If this Security is a Global Security: Payments of principal and any
premium and interest on this Security shall be made to DTC or its nominee, as
Holder of this Security, by wire transfer of immediately available funds.

     If this Security is not a Global Security: Payment of interest on this
Security (other than payments of interest at Maturity) shall be made by check
mailed to the Person entitled thereto at such Person's last address as it
appears in the Security Register or, in the case of a Holder of $50,000,000 or
more in aggregate principal amount of Securities of this series having the same
Interest Payment Date, by wire transfer of immediately available funds to such
account as may have been designated by such Holder. Any such designation for
wire transfer purposes shall be made by filing the appropriate information with
the Paying Agent at its corporate trust office not later than 10 calendar days
prior to the applicable Interest Payment Date and, unless revoked by written
notice to the Paying Agent received by the Paying Agent on or prior to the
Regular Record Date immediately preceding the applicable Interest Payment Date,
shall remain in effect with respect to any further payments with respect to this
Security payable to such Holder. Payment of principal of and interest, if any,
on this Security at Maturity shall be made against presentation of this Security
at the office or agency of the Company maintained for that purpose in New York
City or Minneapolis, Minnesota.

     The Company shall pay any administrative costs imposed by banks on payors
in making payments on this Security in immediately available funds and the
Holder of this Security will

                                       4
<PAGE>

pay any administrative costs imposed by banks on payees in connection with such
payments. Any tax, assessment or governmental charge imposed upon payments on
this Security shall be borne by the Holder of this Security.

     Reference is hereby made to the further provisions of this Security set
forth on the reverse hereof, which further provisions shall for all purposes
have the same effect as if set forth at this place.

     Unless the certificate of authentication hereon has been executed by the
Trustee referred to on the reverse hereof by manual signature or its duly
authorized agent referred to on the reverse hereof by manual signature, this
Security shall not be entitled to any benefit under the Indenture or be valid or
obligatory for any purpose.

                                       5

     IN WITNESS WHEREOF, the Company has caused this instrument to be duly
executed under its corporate seal.

             SUBORDINATED MEDIUM-TERM FLOATING RATE NOTE, SERIES D

                  Due Nine Months or More From Date of Issue

General

     This Security is one of a duly authorized issue of securities of the
Company (herein called the "Securities"), issued and to be issued in one or more
series under an indenture dated as of August 30, 1999, as amended or
supplemented from time to time (herein called the "Indenture"), between the
Company and Bank One Trust Company, N.A. (successor in interest to The First
National Bank of Chicago), as Trustee (herein called the "Trustee", which term
includes any successor trustee under the Indenture), to which Indenture and all
indentures supplemental thereto, reference is hereby made for a statement of the
respective rights, limitations of rights, duties and immunities thereunder of
the Company, the Trustee and the Holders of the Securities, and of the terms
upon which the Securities are, and are to be, authenticated and delivered. This
Security is one of the series of the Securities designated as Subordinated
Medium-Term Notes, Series D, of the Company, which series is limited to an
aggregate principal amount of $10,000,000,000 or the equivalent thereof in one
or more foreign or composite currencies minus the aggregate principal amount of
the Company's Medium-Term Notes, Series C which may be issued from time to time.
The Securities of this series may mature at different times, bear interest, if
any, at different rates, be redeemable at different times or not at all, be
repayable at the option of the Holder at different times or not at all, be
issued at an original issue discount and be denominated in different currencies.

     The Securities are issuable only in registered form without coupons and
will be either (a) book-entry securities represented by one or more global
securities recorded in the book-entry system maintained by the Depository or (b)
certificated securities issued to and registered in the names of, the beneficial
owners or their nominees.

     The indebtedness evidenced by this Security is, to the extent and in the
manner set forth in the Indenture, subordinate and subject in right of payment
to the prior payment in full of the principal of and premium, if any, and
interest on all Senior Debt of the Company, and the Holder of this Security, by
accepting the same, agrees to and shall be bound by the provisions of the
Indenture with respect thereto.

Interest Rate Reset

     The interest rate in effect from the Original Issue Date to the Initial
Interest Reset Date specified on the face hereof shall be the Initial Interest
Rate specified on the face hereof. Commencing with the Initial Interest Reset
Date specified on the face hereof following the

                                       7
<PAGE>

Original Issue Date specified on the face hereof, the rate at which interest on
this Security is payable shall be adjusted daily, weekly, monthly, quarterly,
semi-annually or annually as specified on the face hereof under "Interest Reset
Period". Each such adjusted rate shall be applicable from and including the
Interest Reset Date to which it relates to but not including the next succeeding
Interest Reset Date or until Maturity, as the case may be. Subject to applicable
provisions of law and except as specified herein, on each Interest Reset Date,
the rate of interest on this Security shall be the rate determined with respect
to the Interest Determination Date next preceding such Interest Reset Date in
accordance with the provisions of the applicable heading below and adjusted by
the addition or subtraction of the Spread, if any, specified on the face hereof,
and/or by the multiplication by the Spread Multiplier, if any, specified on the
face hereof.

     If any Interest Reset Date would otherwise be a day that is not a Business
Day, such Interest Reset Date shall be the following Business Day, except that
if the Base Rate specified above is LIBOR or EURIBOR and if such following
Business Day is in the next calendar month, such Interest Reset Date shall be
the immediately preceding Business Day.

     Accrued interest shall be calculated by multiplying the principal amount by
an accrued interest factor. Such accrued interest factor shall be computed by
adding the interest factor calculated for each day in the period for which
interest is being paid. Unless otherwise specified on the face hereof, the
interest factor for each such day will be computed by dividing the interest rate
(expressed as a decimal) applicable to such day by 360, if the Base Rate is the
CD Rate, the Commercial Paper Rate, EURIBOR, the Federal Funds Rate, LIBOR or
the Prime Rate or by the actual number of days in the year, if the Base Rate is
the Treasury Rate or the CMT Rate.

     Unless otherwise specified on the face hereof, all percentages resulting
from any calculation referred to herein shall be rounded, if necessary, to the
nearest one hundred-thousandth of a percentage point, with five one-millionths
of one percentage point rounded upward (e.g., 9.876545% (or .09876545) being
rounded to 9.87655% (or .0987655) and 9.876544% (or .09876544) being rounded to
9.87654% (or .0987654)), and all dollar amounts used in or resulting from any
such calculation on this Security shall be rounded to the nearest cent (with
one-half cent being rounded upwards).

     Notwithstanding the foregoing, the interest rate per annum hereon shall not
be greater than the Maximum Interest Rate, if any, or less than the Minimum
Interest Rate, if any, specified on the face hereof. The Calculation Agent shall
calculate the interest rate hereon in accordance with the foregoing on or before
each Calculation Date.

     The interest rate on this Security shall in no event be higher than the
maximum rate permitted by New York law, as the same may be modified by United
States law of general application.

     At the request of the Holder hereof, the Calculation Agent shall provide to
the Holder hereof the interest rate hereon then in effect and, if determined,
the interest rate that shall

                                       8
<PAGE>

become effective on the next Interest Reset Date with respect to this Security.
The Calculation Agent's determination of any interest rate shall be final and
binding in the absence of manifest error.

     A "Calculation Date", where applicable, for any Interest Determination Date
will be the earlier of:

     .  the tenth calendar day after that Interest Determination Date, or, if
        that day is not a Business Day, the following Business Day; or

     .  the Business Day before the applicable Interest Payment Date or
        Maturity.

Determination of CD Rate

     If the Base Rate specified on the face hereof is CD Rate, the interest rate
per annum determined with respect to any Interest Determination Date specified
on the face hereof (each, a "CD Interest Determination Date") shall equal the
rate on that date for negotiable certificates of deposit having the Index
Maturity specified on the face hereof as published by the Board of Governors of
the Federal Reserve System in "Statistical Release H.15(519), Selected Interest
Rates" or any successor publication of the Board of Governors of the Federal
Reserve System, ("H.15(519)") under the heading "CDs (Secondary Market)."

     The following procedures will be followed if the CD Rate cannot be
determined as described above:

     .  If the above rate is not published in H.15(519) by 9:00 a.m., New York
        City time, on the Calculation Date, the CD Rate will be the rate on the
        applicable CD Interest Determination Date set forth in the daily update
        of H.15(519), available through the world wide website 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 (the "H.15 Daily Update"), for the day in respect of
        certificates of deposit having the Index Maturity specified on the face
        hereof under the caption "CDs (secondary market)."

     .  If that rate is not yet published in either H.15(519) or the H.15 Daily
        Update by 3:00 p.m., New York City time, on the Calculation Date, then
        the Calculation Agent will determine the CD Rate to be the arithmetic
        mean of the secondary market offered rates as of 10:00 a.m., New York
        City time, on that CD Interest Determination Date of three leading
        nonbank dealers in negotiable U.S. dollar certificates of deposit in New
        York City, which may include the agents or their affiliates, selected by
        the Calculation Agent, after consultation with the Company, for
        negotiable certificates of deposit of major United States money center
        banks of the highest credit standing in the market for negotiable
        certificates of deposit with a

                                       9
<PAGE>

        remaining maturity closest to the Index Maturity specified on the face
        hereof in an amount that is representative for a single transaction in
        the market at that time.

     .  If the dealers selected by the Calculation Agent are not quoting as
        described in the previous bullet point, the CD Rate in effect
        immediately before that CD Interest Determination Date will not change
        and will remain the CD Rate in effect on that CD Interest Determination
        Date.

Determination of Commercial Paper Rate

     If the Base Rate specified on the face hereof is Commercial Paper Rate, the
interest rate per annum determined with respect to any Interest Determination
Date specified on the face hereof (each, a "Commercial Paper Interest
Determination Date") shall equal the Money Market Yield, calculated as described
below, of the rate on that date for commercial paper having the Index Maturity
specified on the face hereof as published in H.15(519) under the heading
"Commercial Paper--Nonfinancial."

     The following procedures will be followed if the Commercial Paper Rate
cannot be determined as described above:

     .  If the above rate is not published by 9:00 a.m., New York City time, on
        the Calculation Date, then the Commercial Paper Rate will be the Money
        Market Yield of the rate on the applicable Commercial Paper Interest
        Determination Date for commercial paper having the Index Maturity
        specified on the face hereof as published in the H.15 Daily Update under
        the heading "Commercial Paper--Nonfinancial."

     .  If by 3:00 p.m., New York City time, on that Calculation Date that rate
        is not yet published in either H.15(519) or the H.15 Daily Update, then
        the Calculation Agent will determine the Commercial Paper Rate to be the
        Money Market Yield of the arithmetic mean of the offered rates as of
        11:00 a.m., New York City time, on that Commercial Paper Interest
        Determination Date of three leading dealers of commercial paper in New
        York City, which may include the agents or their affiliates, selected by
        the Calculation Agent, after consultation with the Company, for
        commercial paper having the Index Maturity specified on the face hereof
        placed for an industrial issuer whose bond rating is "AA," or the
        equivalent, from a nationally recognized statistical rating agency.

     .  If the dealers selected by the Calculation Agent are not quoting as
        described in the previous bullet point, the Commercial Paper Rate in
        effect immediately before the Commercial Paper Interest Determination
        Date will not change and will remain the Commercial Paper Rate in effect
        on that Commercial Paper Interest Determination Date.

                                       10

     "Money Market Yield" will be a yield calculated in accordance with the
following formula:

             Money Market Yield  =     D x 360
                                    ------------   x 100
                                    360 - (D x M)

where "D" refers to the applicable annual rate for commercial paper quoted on a
bank discount basis and expressed as a decimal and "M" refers to the actual
number of days in the interest period for which interest is being calculated.

  Determination of EURIBOR

     If the Base Rate specified on the face hereof is EURIBOR, the interest rate
per annum determined with respect to any Interest Determination Date specified
on the face hereof (each, a "EURIBOR Interest Determination Date") shall equal
the rate for deposits in euros as sponsored, calculated and published jointly by
the European Banking Federation and ACI - The Financial Market Association, or
any company established by the joint sponsors for purposes of compiling and
publishing those rates, for the Index Maturity specified on the face hereof as
that rate appears on the display on Bridge Telerate, Inc., or any successor
service, on page 248 or any other page as may replace page 248 on that service,
which is commonly referred to as "Telerate Page 248," as of 11:00 a.m. (Brussels
time).

     The following procedures will be followed if the EURIBOR Rate cannot be
determined as described above:

     .  If the above rate does not appear, the Calculation Agent will request
        the principal Euro-zone, as defined below, office of each of four major
        banks in the Euro-zone interbank market, as selected by the Calculation
        Agent, after consultation with the Company, to provide the Calculation
        Agent with its offered rate for deposits in euros, at approximately
        11:00 a.m. (Brussels time) on the EURIBOR Interest Determination Date,
        to prime banks in the Euro-zone interbank market for the Index Maturity
        specified on the face hereof commencing on the applicable EURIBOR
        Interest Reset Date, and in a principal amount not less than the
        equivalent of U.S. $1 million in euro that is representative of a single
        transaction in euro, in that market at that time. If at least two
        quotations are provided, EURIBOR will be the arithmetic mean of those
        quotations.

     .  If fewer than two quotations are provided, EURIBOR will be the
        arithmetic mean of the rates quoted by four major banks in the Euro-
        zone, as selected by the Calculation Agent, after consultation with the
        Company, at approximately 11:00 a.m. (Brussels time), on the applicable
        EURIBOR Interest Reset Date for loans in euro to leading European banks
        for a period of time equivalent to the Index Maturity specified on the
        face hereof commencing on that EURIBOR

                                       11
<PAGE>

        Interest Reset Date in a principal amount not less than the equivalent
        of U.S. $1 million in euro.

     .  If the banks selected by the Calculation Agent are not quoting as
        described in the previous bullet point, the EURIBOR in effect
        immediately before such EURIBOR Interest Determination Date will not
        change and will remain the EURIBOR in effect on that EURIBOR Interest
        Determination Date.

     "Euro-zone" means the region comprised of member states of the European
Union that adopt the single currency in accordance with the treaty establishing
the European Community, as amended by the treaty on European Union.

     Determination of Federal Funds Rate

     If the Base Rate specified on the face hereof is Federal Funds Rate, the
interest rate per annum determined with respect to any Interest Determination
Date specified on the face hereof (each, a "Federal Funds Interest Determination
Date") shall equal the rate on that day for federal funds as published in
H.15(519) under the heading "Federal Funds (Effective)" as displayed on Bridge
Telerate, Inc. or any successor service on page 120 or any other page as may
replace the applicable page on that service ("Telerate Page 120").

     The following procedures will be followed if the Federal Funds Rate cannot
be determined as described above:

     .  If the above rate is not published by 9:00 a.m., New York City time, on
        the Calculation Date, the Federal Funds Rate will be the rate on the
        applicable Federal Funds Interest Determination Date as published in the
        H.15 Daily Update under the heading "Federal Funds/(Effective)."

     .  If that rate is not yet published in either H.15(519) or H.15 Daily
        Update by 3:00 p.m., New York City time, on the Calculation Date, the
        Calculation Agent will determine the Federal Funds Rate to be the
        arithmetic mean of the rates for the last transaction in overnight U.S.
        dollar Federal Funds arranged by each of three leading brokers of U.S.
        dollar Federal Funds transactions in New York City, which may include
        the agents or their affiliates, selected by the Calculation Agent, after
        consultation with the Company, before 9:00 a.m., New York City time, on
        that Federal Funds Interest Determination Date.

     .  If the brokers selected by the Calculation Agent are not quoting as
        described in the previous bullet point, the Federal Funds Rate in effect
        immediately before that Federal Funds Interest Determination Date will
        not change and will remain the Federal Funds Rate in effect on that
        Federal Funds Interest Determination Date.

   Determination of LIBOR

     If the Base Rate specified on the face hereof is LIBOR, the interest rate
per annum determined with respect to any Interest Determination Date specified
on the face hereof (each, a "LIBOR Interest Determination Date") shall be
determined by the Calculation Agent by reference to the display on Bridge
Telerate Inc., or any successor service, on Page 3750, or any other page as may
replace that page on that service, for the purpose of displaying the London
interbank rates of major banks for the applicable Index Currency ("LIBOR
Telerate"). The "Index Currency" means the currency specified on the face hereof
as the currency for which LIBOR will be calculated, or, if the euro is
substituted for that currency, the Index Currency will be the euro. If no
currency is specified on the face hereof the Index Currency will be U.S.
dollars.

     .  As of the LIBOR Interest Determination Date, LIBOR will be the rate for
        deposits in the Index Currency having the Index Maturity specified on
        the face hereof, commencing on the second London Banking Day immediately
        following that LIBOR Interest Determination Date or, if pounds sterling
        is the Index Currency, commencing on that LIBOR Interest Determination
        Date that appears on LIBOR Telerate as of 11:00 a.m., London time, on
        that LIBOR Interest Determination Date.

     .  If no rate appears, then the Calculation Agent will request the
        principal London offices of each of four 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 on
        the face hereof commencing on the second London Banking Day immediately
        following the LIBOR Interest Determination Date, to prime banks in the
        London interbank market at approximately 11:00 a.m., London time, on
        that LIBOR Interest Determination Date and in a principal amount that is
        representative of a single transaction in that Index Currency in that
        market at that time. If at least two quotations are provided, LIBOR
        determined on that LIBOR Interest Determination Date will be the
        arithmetic mean of those quotations.

     .  If fewer than two quotations are provided, LIBOR will be determined for
        the applicable Interest Reset Date as the arithmetic mean of the rates
        quoted at approximately 11:00 a.m., London time, or some other time
        specified on the face hereof, in the applicable principal financial
        center for the country of the Index Currency on that Interest Reset
        Date, by three major banks in that 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 on the face hereof and in a principal amount that is

                                       13
<PAGE>

          representative of a single transaction in that Index Currency in that
          market at that time.

        . If the banks so selected by the Calculation Agent are not quoting as
          described in the previous bullet point, LIBOR in effect immediately
          before such LIBOR Interest Determination Date will not change and will
          remain the LIBOR in effect on such LIBOR Interest Determination Date.

        If LIBOR Reuters is specified on the face hereof, then LIBOR for each
LIBOR Interest Determination Date will be determined by the Calculation Agent by
reference to the display on the Reuters Monitor Money Rates Service, on the page
specified on the face hereof, or any other page on any designated successor
service, for the purpose of displaying the London interbank rates of major banks
for the applicable Index Currency ("LIBOR Reuters"), and the first bullet point
of the previous paragraph will be replaced with the following:

        . As of the LIBOR Interest Determination Date, LIBOR will be the
          arithmetic mean of the offered rates for deposits in the Index
          Currency having the Index Maturity specified on the face hereof,
          commencing on the second London Banking Day immediately following that
          LIBOR Interest Determination Date, that appear on LIBOR Reuters as of
          11:00 a.m., London time, on that LIBOR Interest Determination Date, if
          at least two offered rates appear on LIBOR Reuters; provided, however,
          that if LIBOR Reuters by its terms provides for only a single rate,
          that single offered rate will be used.

        . If fewer than two rates appear or no rates appear, as applicable, then
          LIBOR shall be calculated as described in the last three bullet points
          in the previous paragraph.

     Determination of Prime Rate

        If the Base Rate specified on the face hereof is Prime Rate, the
interest rate per annum determined with respect to any Interest Determination
Date specified on the face hereof (each, a "Prime Interest Determination Date")
shall equal the rate on such date as published in H.15(519) under the heading
"Bank Prime Loan."

        The following procedures will be followed if the Prime Rate cannot be
determined as described above:

        . If the rate is not published before 9:00 a.m., New York City time, on
          the Calculation Date, then the Prime Rate will be the rate on such
          Prime Interest Determination Date as published in the H.15 Daily
          Update, under the heading "Bank Prime Loan."

        . If the rate is not published before 3:00 p.m., New York City time, on
          the Calculation Date, in either H.15(519) or the H.15 Daily Update,
          then the

                                       14
<PAGE>

          Calculation Agent will determine the Prime Rate to 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
          that bank's prime rate or base lending rate as in effect for that
          Prime Interest Determination Date.

        . If fewer than four rates appear on the Reuters Screen US PRIME1 Page
          on that Prime Interest Determination Date, then the Calculation Agent
          will determine the Prime Rate to 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 360, as of the close of business on
          that Prime Interest Determination Date by at least three major banks
          in New York City, which may include affiliates of the agents, selected
          by the Calculation Agent.

        . If the banks selected are not quoting as described in the previous
          bullet point, the Prime Rate in effect immediately before such Prime
          Interest Determination Date will not change and will remain the Prime
          Rate in effect on such Prime Interest Determination Date.

"Reuters Screen US PRIME1 Page" means the display designated as page "USPRIME1"
on the Reuters Monitor Money Rates Service, or any successor service or any
other page as may replace the USPRIME1 page on that service for the purpose of
displaying prime rates or base lending rates of major United States banks.

     Determination of Treasury Rate

        If the Base Rate specified on the face hereof is Treasury Rate, the
interest rate per annum determined with respect to any Interest Determination
Date specified on the face hereof (each, a "Treasury Interest Determination
Date") shall equal the rate from the auction held on that date of direct
obligations of the United States, which are commonly referred to as "Treasury
bills," having the Index Maturity specified on the face hereof 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 the Treasury bills as published in the H.15(519) Daily
          Update, or such other recognized electronic source used for the
          purpose of displaying such rate, under the heading "U.S. Government
          Securities/Treasury Bills/Auction High."

                                       15
<PAGE>

        The following procedures will be followed if the Treasury Rate cannot
be determined as described above:

        . If the above rate is not published by 3:00 p.m., New York City time,
          on the Calculation Date, the Treasury Rate will be the Bond Equivalent
          Yield of the auction rate of the applicable Treasury bills on that
          Treasury Interest Determination Date as announced by the United States
          Department of the Treasury.

        . In the event that the auction rate of Treasury bills having the Index
          Maturity specified on the face hereof is not published or announced as
          provided above by 3:00 p.m., New York City time, on such Calculation
          Date, or if no auction is held on that Treasury Interest Determination
          Date, then the Calculation Agent will determine the Treasury Rate to
          be the Bond Equivalent Yield of the rate on that Treasury Interest
          Determination Date of Treasury bills having the Index Maturity
          specified on the face hereof 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 Interest
          Determination Date of the applicable Treasury bills as published in
          the H.15 Daily Update under the caption "U.S. Government
          Securities/Treasury Bills/Secondary Market." If that rate is not yet
          published in H.15(519) or the H.15 Daily Update, 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 that
          Treasury Interest Determination Date, of three primary United States
          government securities dealers, which may include the agents or their
          affiliates, selected by the Calculation Agent, for the issue of
          Treasury bills with a remaining maturity closest to the Index Maturity
          specified on the face hereof.

        . If the dealers selected by the Calculation Agent are not quoting as
          described in the previous bullet point, the Treasury Rate in effect
          immediately before that Treasury Interest Determination Date will not
          change and will remain the Treasury Rate in effect on such Treasury
          Interest Determination Date.

"Bond Equivalent Yield" means a yield (expressed as a percentage) calculated as
follows:

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

where "D" refers to the applicable annual rate for the Treasury notes quoted on
a bank discount basis and expressed as a decimal, "N" refers to 365 or 366, as
the case may be, and "M" refers to the actual number of days in the interest
period for which interest is being calculated.

     Determination of CMT Rate

        If the Base Rate specified on the face hereof is CMT Rate, the interest
rate per annum determined with respect to any Interest Determination Date
specified on the face hereof (each, a "CMT Interest Determination Date) shall
equal 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, that CMT Interest
        Determination Date; and

          (ii) if the Designated CMT Telerate Page is 7052, the week or the
        month, as applicable, ended immediately before the week in which the
        related CMT Interest Determination Date occurs.

        The following procedures will be used if the CMT Rate cannot be
determined as described above:

        . If that rate is no longer displayed on the relevant page, or if not
          displayed by 3:00 p.m., New York City time, on the related Calculation
          Date, then the CMT Rate will be the treasury constant maturity rate
          for the Designated CMT Maturity Index, as defined below, as published
          in H.15(519).

        . If that rate is no longer published, or if not published by 3:00 p.m.,
          New York City time, on the related Calculation Date, then the CMT Rate
          will be the 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 Interest Determination Date
          with respect to that 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 the information described above is not provided by 3:00 p.m., New
          York City time, on the related Calculation Date, then the Calculation
          Agent will determine the CMT Rate to be a yield to maturity, based on
          the arithmetic mean of the secondary market closing offer side prices
          as of approximately 3:30 p.m., New York City time, on the CMT Interest
          Determination Date reported, according to their written records, by
          three leading primary United States government securities dealers
          (each a "reference dealer") in New York City selected by the
          Calculation Agent as described in the following sentence, which may
          include the agents or their affiliates. The Calculation Agent will
          select five reference dealers, after consultation with the Company,
          and will eliminate the highest quotation, or, in the event of overlap,
          one of the highest and the lowest quotation, or, in the event of

                                       17
<PAGE>

          overlap, one of the lowest, for the most recently issued direct
          noncallable fixed rate obligations of the United States, which are
          commonly referred to as "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 cannot obtain three such Treasury notes
          quotations, the Calculation Agent will determine the CMT Rate to be a
          yield to maturity based on the arithmetic mean of the secondary market
          offer side prices as of approximately 3:30 p.m., New York City time,
          on the CMT Interest Determination Date of three reference dealers in
          New York City, which may include the agents or their affiliates,
          selected using the same method described above, for Treasury notes
          with an original maturity of the number of years closest to but not
          less than 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 $100,000,000. If two Treasury notes with an original
          maturity as described above 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.

        . If three or four, but not five, of the reference dealers are quoting
          as described immediately above, then the CMT Rate will be based on the
          arithmetic mean of the offer prices obtained and neither the highest
          nor the lowest of the quotes will be eliminated.

        . If fewer than three reference dealers selected by the Calculation
          Agent are quoting as described above, the CMT Rate in effect
          immediately before such CMT Interest Determination Date will not
          change and will remain the CMT Rate in effect on such CMT Interest
          Determination Date.

"Designated CMT Telerate Page" means the display on Bridge Telerate, Inc., or
any successor service, on the page designated on the face hereof, or any other
page as may replace such page on that service for the purpose of displaying
Treasury Constant Maturities as reported in H.15(519). If no page is specified
on the face hereof, the Designated CMT Telerate Page will be 7052, for the most
recent week.

"Designated CMT Maturity Index" means the original period to maturity of the
U.S. Treasury notes (either 1, 2, 3, 5, 7, 10, 20 or 30 years) specified on the
face hereof with respect to which the CMT Rate will be calculated. If no
maturity is specified on the face hereof, the Designated CMT Maturity Index will
be two years.
