         MINNESOTA MINING AND MANUFACTURING 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 such offices and agencies, 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 Federal Funds Rate", "Determination of
LIBOR", "Determination of Prime Rate", "Determination of Treasury Rate" or
"Determination of CMT Rate", depending upon

<PAGE>

whether the Base Rate is CD Rate, Commercial Paper Rate, 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 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, Sunday or a legal holiday or a day on which banking institutions are
authorized or required by law or regulation to close in ____________________ or
___________________, and (b) if the Base Rate specified above is LIBOR, any such
day 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) 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,

                                       3
<PAGE>

"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 _________________ and ________________. The
Company has initially appointed __________________ as the Paying Agent at its
offices at ___________________________________________________________________.

         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, 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 15 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 __________________ or
__________________.

         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 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.

                   MEDIUM-TERM FLOATING RATE NOTE, SERIES ____

                   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 ________________, as amended or
supplemented from time to time (herein called the "Indenture"), between the
Company and _____________________________, 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, which series is limited to an aggregate principal amount of
$_________________ or the equivalent thereof in one or more foreign or composite
currencies, designated as Medium-Term Notes, Series __, of the Company. 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.

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 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.

                                       7
<PAGE>

         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 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, 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 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.

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 such date for negotiable certificates of deposit having the
specified Index Maturity as published by the Board of Governors of the Federal
Reserve System in "Statistical Release H.15(519), Selected Interest

                                       8
<PAGE>

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 shall be followed if the CD Rate cannot be
determined as described above:

          o    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 shall 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 ("H.15 Daily Update"), or another
               recognized electronic source used for the purpose of displaying
               this rate, for the day in respect of certificates of deposit
               having the Index Maturity specified on the face hereof under the
               caption "CDs (secondary market)."

          o    If such rate is not yet published in either H.15(519) or the H.15
               Daily Update or another recognized electronic source by 3:00
               p.m., New York City time, on the Calculation Date, then the
               Calculation Agent shall 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 such CD Interest Determination Date
               of three leading nonbank dealers in negotiable U.S. dollar
               certificates of deposit in New York City selected by the
               Calculation Agent for negotiable certificates of deposit in a
               denomination of $5,000,000 of major United States money center
               banks of the highest credit standing (in the market for
               negotiable certificates of deposit) with a remaining maturity
               closest to the Index Maturity specified on the face hereof.

          o    If the dealers selected by the Calculation Agent are not quoting
               as mentioned immediately above, the CD Rate in effect immediately
               prior to such CD Interest Determination Date shall not change and
               shall remain the CD Rate in effect on such 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 such 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."

                                       9
<PAGE>

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

          o    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
               shall 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 H.15 Daily Update, or another recognized electronic
               source used for the purpose of displaying this rate, under the
               heading "Commercial Paper--Nonfinancial."

          o    If by 3:00 p.m., New York City time, on such Calculation Date
               such rate is not yet published in either H.15(519) or H.15 Daily
               Update or another recognized electronic source, then the
               Calculation Agent shall determine the Commercial Paper Rate to be
               the Money Market Yield of the arithmetic mean of the offered
               rates of 11:00 a.m., New York City time, on such Commercial Paper
               Interest Determination Date of three leading dealers of
               commercial paper in New York City selected by the Calculation
               Agent 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.

          o    If the dealers selected by the Calculation Agent are not quoting
               as mentioned immediately above, the Commercial Paper Rate in
               effect immediately prior to such Commercial Paper Interest
               Determination Date shall not change and shall remain the
               Commercial Paper Rate in effect on such Commercial Paper Interest
               Determination Date.

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

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

where "D" refers to the applicable per annum 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 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)."

                                       10
<PAGE>

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

          o    If the above rate is not published by 9:00 a.m., New York City
               time, on the Calculation Date, the Federal Funds Rate shall be
               the rate on the applicable Federal Funds Interest Determination
               Date as published in H.15 Daily Update, or another recognized
               electronic source used for the purpose of displaying this rate,
               under the heading "Federal Funds/(Effective)."

          o    If such rate is not yet published in either H.15(519) or H.15
               Daily Update or another recognized electronic source by 3:00
               p.m., New York City time, on the Calculation Date, the
               Calculation Agent shall 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 selected by the Calculation Agent prior to 9:00 a.m.,
               New York City time, on such Federal Funds Interest Determination
               Date.

          o    If the brokers selected by the Calculation Agent are not quoting
               as mentioned above, the Federal Funds Rate in effect immediately
               prior to such Federal Funds Interest Determination Date shall not
               change and shall remain the Federal Funds Rate in effect on such
               Federal Funds Interest Determination Date.

DETERMINATION OF LIBOR

         If the Base Rate specified on the face hereof is the London interbank
offered rate ("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 as
follows:

          o    As of the LIBOR Interest Determination Date, LIBOR shall be
               either:

               o    if "LIBOR Reuters" is specified on the face hereof, the
                    arithmetic mean of the offered rates (unless the Designated
                    LIBOR Page (as defined below) by its terms provides only for
                    a single rate, in which case such single rate shall be used)
                    for deposits in the Index Currency (as defined below) having
                    the Index Maturity specified on the face hereof, commencing
                    on the applicable Interest Reset Date, that appear (or, if
                    only a single rate is provided as aforesaid, appears) on the
                    Designated LIBOR Page as of 11:00 a.m., London time, on such
                    LIBOR Interest Determination Date; or

               o    if "LIBOR Telerate" is specified on the face hereof or if
                    neither "LIBOR Reuters" nor "LIBOR Telerate" is specified on
                    the face hereof as the method for calculating LIBOR, the
                    rate for deposits in the Index Currency

                                       11
<PAGE>

                    having the Index Maturity specified on the face hereof,
                    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.

          If fewer than the required number of applicable rates appear, LIBOR on
          such LIBOR Interest Determination Date shall be determined in
          accordance with the provisions described immediately below.

          o    With respect to a LIBOR Interest Determination Date on which
               fewer than the required number of applicable rates appear on the
               Designated LIBOR Page as specified immediately above, the
               Calculation Agent will request the principal London offices of
               each of four major reference banks in the London interbank
               market, as selected by the Calculation Agent, 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 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 not less than
               $1,000,000 (or the equivalent in the Index Currency as
               applicable) that is representative for a single transaction in
               such Index Currency in such market at such time. If at least two
               quotations are so provided, then LIBOR on such LIBOR Interest
               Determination Date shall be the arithmetic mean of such
               quotations.

          o    If only one or no such quotations are so provided, then LIBOR on
               such LIBOR Interest Determination Date shall be the arithmetic
               mean of the rates quoted at approximately 11:00 a.m., in the
               applicable principal financial center for the country of the
               Index Currency, on such LIBOR Interest Determination Date by
               three major banks in such principal financial center selected by
               the Calculation Agent for loans in the Index Currency to leading
               European banks, having the Index Maturity specified on the face
               hereof and in a principal amount not less than $1,000,000 (or the
               equivalent in the Index Currency as applicable) that is
               representative for a single transaction in such Index Currency in
               such market at such time.

          o    If the banks so selected by the Calculation Agent are not quoting
               as mentioned immediately above, LIBOR in effect immediately prior
               to such LIBOR Interest Determination Date shall not change and
               shall remain the LIBOR in effect on such LIBOR Interest
               Determination Date.

         For purposes of the preceding discussion, the following capitalized
terms have the following meanings:

         "Index Currency" means the currency specified on the face hereof (which
may be a composite currency) for which LIBOR shall be calculated. If no such
currency is specified, the Index Currency shall be U.S. dollars.

               service)) for the purpose of displaying the London interbank
               rates of major banks for the applicable Index Currency; or

          o    if "LIBOR Telerate" is designated on the face hereof or neither
               "LIBOR Reuters" nor "LIBOR Telerate" is designated on the face
               hereof as the method for calculating LIBOR, the display on Dow
               Jones Markets Limited (or any successor service) on page 3750 if
               the U.S. dollar is the Index Currency or with respect to any
               other Index Currency, on the page specified on the face hereof
               (or any other page as may replace such page or such service (or
               any successor service)) for the purpose of displaying the London
               interbank rates of major banks for the applicable Index Currency.

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 shall be followed if the Prime Rate cannot be
determined as described above:

          o    If the rate is not published prior to 9:00 a.m., New York City
               time, on the Calculation Date, then the Prime Rate shall be the
               rate on such Prime Interest Determination Date as published in
               H.15 Daily Update, or another recognized electronic source used
               for the purpose of displaying this rate, opposite the caption
               "Bank Prime Loan."

          o    If the rate is not published prior to 3:00 p.m., New York City
               time, on the Calculation Date, in either H.15(519) or H.15 Daily
               Update or another recognized electronic source, then the
               Calculation Agent shall 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 such bank's prime rate or base lending rate as
               in effect for that Prime Interest Determination Date.

          o    If fewer than four rates appear on the Reuters Screen US Prime 1
               Page on such Prime Rate Interest Determination Date, then the
               Calculation Agent shall 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

                                       13

               Interest Determination Date by at least three major money center
               banks in New York City selected by the Calculation Agent.

          o    If the banks selected are not quoting as mentioned immediately
               above, the Prime Rate in effect immediately prior to such Prime
               Interest Determination Date shall not change and shall 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 such other page as may
replace the US Prime1 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 applicable to the auction held on such date of
direct obligations of the United States ("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 hereinafter defined) of
the rate for such Treasury bills as published in 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".

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

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

          o    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 such auction is held on such
               Treasury Interest Determination Date, then the Calculation Agent
               shall determine the Treasury Rate to be the Bond Equivalent Yield
               of the rate on such Treasury Rate 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.

               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
               shall be calculated by the Calculation Agent and shall 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 Interest Determination Date, of three
               leading primary United States government securities dealers
               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.

          o    If the dealers selected by the Calculation Agent are not quoting
               as mentioned immediately above, the Treasury Rate in effect
               immediately prior to such Treasury Interest Determination Date
               shall not change and shall remain the Treasury Rate in effect on
               such Treasury Interest Determination Date.

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

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

where "D" refers to the applicable per annum rate for the security 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, such CMT
         Interest Determination Date; and

                                       15
<PAGE>

                  (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 shall be used if the CMT Rate cannot be
determined as described above:

          o    If such 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 shall be such treasury
               constant maturity rate for the Designated CMT Maturity Index (as
               defined below) as published in H.15(519).

          o    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 shall 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
               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).

          o    If such information is not provided by 3:00 p.m., New York City
               time, on the related Calculation Date, then the Calculation Agent
               shall 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. The Calculation Agent shall select five
               Reference Dealers and shall eliminate the highest quotation (or,
               in the event of overlap, one of the highest) and the lowest
               quotation (or, in the event of overlap, 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.

          o    If the Calculation Agent cannot obtain three such Treasury notes
               quotations, the Calculation Agent shall 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 (selected using the same
               method described above) for Treasury notes with an original

                                       16
<PAGE>

               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 $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 shall obtain quotations for the Treasury note
               with the shorter remaining term to maturity.

          o    If three or four (but not five) of such Reference Dealers are
               quoting as described above, then the CMT Rate shall be based on
               the arithmetic mean of the offer prices obtained and neither the
               highest nor the lowest of such quotes shall be eliminated.

          o    If fewer than three Reference Dealers selected by the Calculation
               Agent are quoting as mentioned immediately above, the CMT Rate in
               effect immediately prior to such CMT Interest Determination Date
               shall not change and shall remain the CMT Rate in effect on such
               CMT Interest Determination Date.

         "Designated CMT Telerate Page" means the display on the Telerate (or
any successor service) on the page specified 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 such page is
specified, the Designated CMT Telerate Page shall be 7052, for the most recent
week.

         "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 on the face hereof with respect to which the CMT Rate shall be

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.

         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 Government
Obligations as provided in Section 401 or 403 of the Indenture, such payments
shall be made only from proceeds of such money or Government Obligations.

DEFEASANCE AND COVENANT DEFEASANCE

         The Indenture contains provisions for defeasance at any time of (a) the

certain Events of Default, upon compliance by the Company with certain
conditions set forth therein, which provisions apply to this Security.

REDEMPTION

         If so provided on the face hereof, the Company may at its option redeem
this Security in whole or from time to time in part in increments of $1,000

than the minimum authorized denomination hereof) on or after the date designated
as the Initial Redemption Date on the face hereof at 100% of the unpaid
principal amount hereof or the portion thereof redeemed multiplied by a
percentage (the "Redemption Percentage"), together with accrued interest, if
any, to the Redemption Date. The Redemption Percentage shall initially be equal
to the Initial Redemption Percentage specified on the face hereof and shall
decline at each anniversary of the Initial Redemption Date by the amount of the
Annual Redemption Percentage Reduction specified on the face hereof, until the
Redemption Percentage is equal to 100%. The Company may exercise such option by
causing the Trustee to mail a notice of such redemption at least 30 but not more
than 60 days prior to the applicable Redemption Date to each Holder of the
Securities of this series to be redeemed. In the event of redemption of this
Security in part only, the Company shall issue a new Security or Securities for
the unredeemed portion hereof in the name of the Holder hereof upon the

tenor and terms are to be redeemed, the Securities to be redeemed shall be
selected by the Trustee by such method as the Trustee shall deem fair and
appropriate.

Company (herein called the "Securities"), issued and to be issued in one or more
series under an indenture dated as of _______________, as amended or
supplemented from time to time (herein called the "Indenture"), between the
Company and __________________________________, 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 designated on
the face hereof, limited in aggregate principal amount to $____________.

         [**The Securities of this series are not subject to redemption prior to
______________.] [**The Securities of this series are subject to redemption
prior to _________________ as follows: ________________________________________]
The Securities will not be entitled to any sinking fund.

         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.

         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 each series to be affected. The Indenture also contains
provisions permitting the Holders of specified percentages in principal amount
of the Securities of each series at the time Outstanding, on behalf of the
Holders of all Securities of such series, to waive compliance by the Company
with certain provisions of the Indenture and certain past defaults under the
Indenture and their consequences. Any such consent or waiver by the Holder of
this 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

                                       4
<PAGE>

exchange herefor or in lieu hereof, whether or not notation of such consent or
waiver is made upon this Security.

         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
conditions set forth therein, which provisions apply to this Security.

the office or agency of the Company in the City of ___________________, or the
City of _________________, or, at the option of the Holder hereof, at the office
or agency to be maintained for that purpose in ______________________, a new
Security or Securities of this series in authorized denominations for an equal
aggregate principal amount will be issued to the transferee in exchange herefor,
as provided in the Indenture and subject to the limitations provided therein and
to the limitations described below, without charge except for any tax or other
governmental charge imposed in connection therewith.

         This Security is exchangeable for definitive Securities in registered
form only if (x) the Depositary notifies the Company that it is unwilling or
unable to continue as Depositary for this Security or if at any time the
Depositary ceases to be a clearing agency registered under the Securities
Exchange Act of 1934, as amended, (y) the Company in its sole discretion
determines that this Security shall be exchangeable for definitive Securities in
registered form and notifies the Trustee thereof or (z) an Event of Default with
respect to the Securities represented hereby has occurred and is continuing. If
this Security is exchangeable pursuant to the preceding sentence, it shall be
exchangeable for definitive Securities in registered form, bearing interest at
the same rate, having the same date of issuance, redemption provisions, Stated
Maturity and other terms and of authorized denominations aggregating a like
amount.

         This Security may not be transferred except as a whole by the
Depositary to a nominee of the Depositary or by a nominee of the Depositary to
the Depositary or another nominee of the Depositary or by the Depositary or any
such nominee to a successor of the Depositary or a nominee of such successor.
Except as provided above, owners of beneficial interests in this global Security
will not be entitled to receive physical delivery of Securities in definitive
form and will not be considered the Holders hereof for any purpose under the
Indenture.

         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 Government
Obligations as provided in Section 401 or 403 of the Indenture, such payments
will be made only from proceeds of such money or Government Obligations.

         Prior to due presentment of this Security 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 Security is registered as the owner hereof for all
purposes, whether or not this Security be

                                       5
<PAGE>

overdue, and neither the Company, the Trustee nor any such agent shall be
affected by notice to the contrary.

         No recourse shall be had for the payment of the principal of or the
interest on this Security, or for any claim based hereon, or otherwise in
respect hereof, or based on or in respect of the Indenture or any indenture
supplemental thereto, against any incorporator, stockholder, officer or
director, as such, past, present or future, of the Company or any successor
corporation, whether by virtue of any constitution, statute or rule of law, or
by the enforcement of any assessment or penalty or otherwise, all such liability
being, by the acceptance hereof and as part of the consideration for the
