corporation under the Indenture referred to on the reverse hereof), for value
received, hereby promises to pay to, or registered assigns, the principal sum
of

                                                                               3

     U.S. DOLLARS on the Maturity Date specified above, and to pay interest
thereon at a rate per annum equal to the Initial Interest Rate specified above
until the first Interest Reset Date specified above following the Original Issue
Date specified above and thereafter at a rate determined in accordance with the
provisions on the reverse hereof under the heading "Determination of Commercial
Paper Rate", "Determination of Prime Rate", "Determination of LIBOR",
"Determination of Treasury Rate", "Determination of Federal Funds Rate" or
"Determination of CD Rate", depending upon whether the Interest Rate Basis
specified above is the Commercial Paper Rate, Prime Rate, LIBOR, Treasury Rate,
Federal Funds Rate or CD Rate, which rate may be adjusted by adding or
subtracting the Spread or multiplying by the Spread Multiplier (as such terms
are defined below) depending on whether a Spread or Spread Multiplier is
designated above, until the principal hereof is paid or duly made available for
payment. In addition, a Floating Rate Note may bear interest at the lowest or
highest or average of two or more interest rate formulae. The "Spread", if any,
is the number of basis points designated above, and the "Spread Multiplier", if
any, is the percentage designated above. The Company will pay interest monthly,
quarterly, semi-annually or annually as specified above under "Interest Payment
Period", commencing with the first Interest Payment Date specified above next
succeeding the Original Issue Date and thereafter on the Interest Payment Dates
as specified above, and on the Maturity Date. The interest so payable, and
punctually paid or duly provided for, on any Interest Payment Date will, as
provided in such Indenture, be paid to the Person in whose name this Security
(or one or more Predecessor Securities) is registered at the close of business
on the Regular Record Date for such interest set forth above (whether or not a
Business Day), next preceding such Interest Payment Date; provided, however,
                                                          --------  -------
that interest payable at Maturity shall be payable to the Person to whom
principal shall be payable. Except as otherwise provided in the Indenture, any
such interest not so punctually paid or duly provided for will forthwith cease
to be payable to the Holder on such Regular Record Date and may either be paid
to the Person in whose name this 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
thereof 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 said Indenture. Payment of the
principal, premium, if any, and interest on this Security will be made at the
principal corporate trust office of the Trustee in Cincinnati, Ohio, or such
other office or agency of the Company as may be designated by it for such
purpose in Cincinnati, Ohio (the "Paying Agent"), in such coin or currency of
the United States of America as at the time of payment is legal tender for
payment of public and private debts; provided, however, that at the option of
the Company payment of interest (except at Maturity) may be made by United
States dollar check mailed to the address of the Person entitled thereto as such
address shall appear in the Security Register. Payment of the principal,
premium, if any, and interest on this Security due at Maturity will be made in
immediately available funds upon surrender of this Security to the Paying Agent;
provided that this Security is presented to the Paying Agent in time for the
Paying Agent to make such payment in accordance with its normal procedures.
"Maturity" shall mean the date on which the principal of this Security or an
installment of principal becomes due, whether on the Maturity Date specified
above, upon redemption or otherwise.

                  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 IN FULL AT THIS PLACE.

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

                                 (Floating Rate)

     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 (herein called the "Indenture"), between
the Company and U.S. Bank, National Association, 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.

     This Security may not be redeemed prior to the Redemption Date set forth on
the face hereof. If no Redemption Date is so set forth, this Security is not
redeemable prior to the Maturity Date. On or after the Redemption Date set forth
on the face hereof, this Security is redeemable in whole or in part in
increments of U.S. $1,000 at the option of the Company at a redemption price
equal to 100% of the principal amount to be redeemed together with interest
thereon to the date of redemption.

Securities, not more than 60 nor less than 30 days prior to the date fixed for
redemption, all as provided in the Indenture.

     In the event of redemption of this Security in part only, a new Security or

     Commencing with the first Interest Reset Date specified on the face hereof
following the Original Issue Date, the rate at which interest on this Security
is payable shall be adjusted daily, weekly, monthly, quarterly, semi-annually or
annually as shown on the face hereof under "Interest Rate Reset Period";
provided, however, that the interest rate in effect hereon for the 10 days
--------  -------
immediately prior to the Maturity hereof, shall be that in effect on the 10th
day preceding the Maturity hereof. Each such adjusted rate shall be applicable
on and after 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.
If any Interest Reset Date specified on the face hereof would otherwise be a day
that is not a Business Day, such Interest Reset Date shall be postponed to the
next succeeding day that is a Business Day, except that if (i) the rate of
interest on the Security shall be determined in accordance with the provisions
of the heading "Determination of LIBOR" below, and (ii) such London Banking Day
is in the next succeeding calendar month, such Interest Reset Date shall be the
immediately preceding London Banking Day. "Business Day" means any day, other
than a Saturday or Sunday, that meets each of the following applicable
requirements. The day is: (a) not a day on which banking institutions are
authorized or required by law or regulation to be closed in The City of New
York, (b) with respect to LIBOR Notes, a London Banking Day, (c) with respect to
Foreign Currency Notes (other than Foreign Currency Notes denominated in euro
only), not a day on which banking institutions are authorized or required by law
or regulation to be closed in the principal financial center in the country of
the Specified Currency and (d) with respect to Foreign Currency Notes
denominated in euro, any date on which the Trans-European Automated Real-Time
Gross Settlement Express Transfer (TARGET) System is open. "London Banking Day"
means any day on which dealings in deposits in United States dollars are
transacted in the London interbank market. 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 in accordance with the
provisions of the applicable heading below.

     The interest rate on this Security will 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 applicability.

     DETERMINATION OF COMMERCIAL PAPER RATE. The interest rate payable with
respect to this Security shall be

<PAGE>

                                                                               9

calculated by the Calculation Agent with reference to the Commercial Paper Rate
and the Spread or Spread Multiplier, if any, specified on the face hereof.
"Commercial Paper Rate" means, with respect to each Interest Determination Date
specified on the face hereof, the Money Market Yield (calculated as described
below) on such date of the rate for commercial paper 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" ("H.15(519)") under the heading "Commercial Paper - Nonfinancial". In the
event that such rate is not published prior to 3:00 P.M., New York City time, on
the Calculation Date pertaining to such Interest Determination Date, then the
Commercial Paper Rate on such Interest Determination Date will be the Money
Market Yield of the rate for commercial paper having the Index Maturity
specified on the face hereof as published in the daily update of H.15(519),
available through the world wide web site of the Board of Governors of the
Federal Reserve System at http://www.bog.frb.fed.us/releases/h15/update (the
"H.15 Daily Update") under the heading "Commercial Paper -- Nonfinancial" (with
an Index Maturity of one month or three months being deemed to be equivalent to
an Index Maturity of 30 days or 90 days respectively), or any successor site or
publication or heading. 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
in any successor publications), the Commercial Paper Rate for that Interest
Determination Date will be the Money Market Yield of the arithmetic mean, as
calculated by the Calculation Agent on such Calculation Date, of the offered
rates, as of 11:00 A.M., New York City time, on that Interest Determination
Date, of three leading dealers of commercial paper in The City of New York
selected by the Calculation Agent (which may include one or more of the Agents
or their affiliates) for commercial paper having the Index Maturity specified on
the face hereof placed for a non-financial issuer whose bond rating is "Aa", or
the equivalent, from a nationally recognized rating agency; provided, however,
                                                            --------- -------
that if fewer than three dealers selected as aforesaid by the Calculation Agent
are quoting as mentioned in this sentence, the Commercial Paper Rate will be the
Commercial Paper Rate in effect on such Interest Determination Date.

     "Money Market Yield" means a yield (expressed as a percentage rounded to
the next higher one hundred thousandth of a percentage point) calculated in
accordance with the following formula:

                       Money Market Yield = D x 360   x 100
                                            --------

<PAGE>

                                                                              10

                                                  360 - (D x M)


where "D" refers to the 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 PRIME RATE. The interest rate payable with respect to this
Security shall be calculated by the Calculation Agent with reference to the
Prime Rate and the Spread or Spread Multiplier, if any, specified on the face
hereof. "Prime Rate" means, with respect to each Interest Determination Date
specified on the face hereof, the rate set forth on such date in H.15(519) under
the heading "Bank Prime Loan", or any successor publication or heading. If the
rate is not published in H.15(519) prior to 3:00 P.M., New York City time, on
the Calculation Date, then the Prime Rate will be the rate on such Interest
Determination Date as published in H.15 Daily Update opposite the caption "Bank
Prime Loan". In the event that such rate is not published in either H.15(519) or
H.15 Daily Update prior to 3:00 P.M., New York City time, on such Interest
Determination Date, then the Prime Rate will be determined by the Calculation
Agent and will be the arithmetic mean of the rates of interest publicly
announced by each bank that appears on the Reuters Screen USPRIME1 Page, or any
successor screen or page, as such bank's prime rate or base lending rate as in
effect for that Interest Determination Date at 11:00 A.M. New York City time. If
fewer than four such rates appear on the Reuters Screen USPRIME1 Page for the
Interest Determination Date, the Prime Rate will be the arithmetic mean of the
announced prime rates quoted (on the basis of the actual number of days in the
year divided by 360) as of the close of business on such Interest Determination
Date by at least three major money center banks in The City of New York (which
may include the Agents or their affiliates) selected by the Calculation Agent.
If fewer than two such quotations are provided, the Prime Rate shall be
determined on the basis of the rates furnished in The City of New York by the
appropriate number of substitute banks or trust companies organized and doing
business under the laws of the United States, or any state thereof, having total
equity capital of at least $500 million and being subject to supervision or
examination by federal or state authority, selected by the Calculation Agent to
provide such rate or rates; provided, however, that if the banks selected as
                            --------   ------
aforesaid are not quoting as mentioned in this sentence, the Prime Rate will be
the Prime Rate then in effect on such Interest Determination Date.

     "Reuters Screen USPRIME1 Page" means the display on the Reuter Monitor
Money Rates Service (or any successor service) on the "USPRIME1" page (or such
other page as may replace the USPRIME1 page on such service) for the purpose of
displaying prime rates or base lending rates of major United States banks.

     DETERMINATION OF LIBOR. The interest rate payable with respect to this
Security shall be calculated with reference to LIBOR and the Spread or Spread
Multiplier, if any, specified on the face hereof. "LIBOR" will be determined
with respect to each Interest Determination Date specified on the face hereof by
the Calculation Agent in accordance with the following provisions:

         (i)  With respect to each Interest Determination Date, LIBOR will be
   either (a) if "LIBOR Reuters" is specified on the face hereof, 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 applicable Interest
   Reset Date, that appear (or, if only a single rate is required as aforesaid,
   appears) on the Designated LIBOR Page as of 11:00 A.M., London time, on such
   LIBOR Interest Determination Date, if at least two of these offered rates
   appear on the Designated LIBOR Page (if the Designated LIBOR Page by its
   terms provides for only a single rate, that single rate will be used
   regardless of the foregoing provisions requiring more than one rate), (b) if
   "LIBOR Telerate" is specified on the face hereof as the method for
   calculating LIBOR, the rate for deposits in the Index Currency 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 Interest Determination Date or (c) if neither "LIBOR
   REUTERS" nor "LIBOR Telerate" is specified on the face hereof as the method
   for calculating LIBOR, the rate as if "LIBOR Telerate" had been so specified.
   If fewer than two such offered rates so appear, or if no such rate so
   appears, as applicable, LIBOR on such Interest Determination Date will be
   determined in accordance with the provisions described in clause (ii) below.

         (ii) With respect to an Interest Determination Date on which fewer than

         market, as selected by the Calculation Agent, to provide the

         banks in the London interbank market at approximately 11:00 A.M.,
         London time, on such LIBOR Interest Determination Date and in a

         such Index Currency in such market at such time. If at least two such

         Date will be the arithmetic mean of such quotations. If fewer than two
         such quotations are so provided, then LIBOR on such Interest
         Determination Date will be the arithmetic mean of the rates quoted at
         approximately 11:00 A.M., in the applicable Principal Financial Center,
         on such Interest Determination Date by three major banks in such
         Principal Financial Center (which may include the Agents or their
         affiliates) 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 that is representative for
         a single transaction in such Index Currency in such market at such
         time; provided, however, that if the banks so selected by the
               --------  -------
         Calculation Agent are not quoting as mentioned in this sentence, LIBOR
         determined as of such LIBOR Interest Determination Date will be LIBOR
         in effect on such Interest Determination Date.

              "Designated LIBOR Page" means (a) if "LIBOR Reuters" is specified
on the face hereof, the display on the Reuter Monitor Money Rates Service (or
any successor service) on the page specified on the face hereof (or any other

     DETERMINATION OF TREASURY RATE. The interest rate payable with respect to
this Security shall be calculated by the Calculation Agent with reference to the
Treasury Rate and the Spread or Spread Multiplier, if any, specified on the face
hereof. "Treasury Rate" means, with respect to each Interest Determination Date,
the rate from the most recent auction of direct obligations of the United States
("Treasury bills") having the Index Maturity specified on the face hereof as
such rate appears on the display designated as Page 56 or the display designated
as Page 57 on the Dow Jones Telerate Service under the heading "AVGE INVEST
YIELD", or any successor publication or heading, or, if not so published by 3:00
P.M., New York City time, on the Calculation Date pertaining to such Interest
Determination Date, the auction average rate (expressed as a bond equivalent on
the basis of a year of 365 or 366 days, as applicable, and applied on a daily
basis) for such auction as otherwise announced by the United States Department
of the Treasury. In the event that the results of the auction of Treasury bills
having the Index Maturity specified on the face hereof are not published or
reported as provided above by 3:00 P.M., New York City time, on such date, or if
no such auction is held in a particular week, then the Treasury Rate shall be
the rate as published in H.15(519) under the heading "U.S. Government
Securities/Treasury Bills/Secondary Market", or any successor publication or
heading. In the event that such rate is not so published by 3:00 P.M., New York
City time, on the relevant Calculation Date, then the Treasury Rate shall be
calculated by the Calculation Agent and shall be a yield to maturity (expressed
as a bond equivalent on the basis of a year of 365 or 366 days, as applicable,
and applied on a daily basis) of the arithmetic mean, as calculated by the
Calculation Agent on such Calculation Date, of the secondary market bid rates as
of approximately 3:30 P.M., New York City time, on such Interest Determination
Date, of three leading primary United States government securities dealers in
The City of New York selected by the Calculation Agent (which may include one or
more of the Agents or their affiliates), for the issue of Treasury bills with a
remaining maturity closest to the specified Index Maturity; provided, however,
                                                            --------  -------
that if fewer than three of the dealers selected as aforesaid by the Calculation
Agent are quoting as mentioned in this sentence, the Treasury Rate will be the
Treasury Rate in effect on such Interest Determination Date.

                                                                              14

              DETERMINATION OF FEDERAL FUNDS RATE. The interest rate payable
with respect to this Security shall be calculated by the Calculation Agent with
reference to the Federal Funds Rate and the Spread or Spread Multiplier, if any,
specified on the face hereof. "Federal Funds Rate" means, with respect to each
Interest Determination Date, the rate on such date for Federal Funds as
published in H.15(519) under the heading "Federal Funds (Effective)", or any
successor publication or heading. In the event that such rate is not published
prior to 3:00 P.M., New York City time, on the Calculation Date pertaining to
such Interest Determination Date, then the Federal Funds Rate will be the rate
on such Interest Determination Date for United States dollar federal funds as
published in H.15 Daily Update under the heading "Federal Funds (Effective)", or
any successor publication or heading. 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 in any successor publications), the Federal Funds Rate for that
Interest Determination Date shall be the arithmetic mean, as calculated by the
Calculation Agent on such Calculation Date, of the rates for the last
transaction in overnight Federal Funds arranged by three leading brokers of
Federal Funds transactions in The City of New York as of 9:00 a.m., New York
City time, on such Federal Funds Rate Interest Determination Date; provided,
                                                                   --------
however, that if fewer than three brokers selected as aforesaid by the
-------
Calculation Agent are quoting as mentioned in this sentence, the Federal Funds
Rate will be the Federal Funds Rate in effect on such Interest Determination
Date.

              DETERMINATION OF CD RATE. The interest rate payable with respect
to this Security shall be calculated by the Calculation Agent with reference to
the CD Rate and the Spread or Spread Multiplier, if any, specified on the face
hereof. "CD Rate" means, with respect to each CD Rate Interest Determination
Date, the rate on such date for negotiable certificates of deposit having the
Index Maturity specified on the face hereof as published in H.15(519) under the
heading "CDs (Secondary Market)", or any successor publication or heading. In
the event that such rate is not published prior to 3:00 P.M., New York City
time, on the Calculation Date pertaining to such Interest Determination Date,
then the CD Rate shall be the rate on such Interest Determination Date set forth
in H.15 Daily Update for that day in respect of negotiable certificates of
deposit having the Index Maturity specified on the face hereof under the caption
"CDs (Secondary Market)". If by 3:00 P.M., New York City time, on such
Calculation Date such rate is not yet

<PAGE>

                                                                              15

published in either H.15(519) or H.15 Daily Update (or in any successor
publications), the CD Rate for that Interest Determination Date shall be
calculated by the Calculation Agent and shall be the arithmetic mean of the
secondary market offered rates, as of 10:00 A.M., New York City time, on that
Interest Determination Date, of three leading nonbank dealers of negotiable U.S.
dollar certificates of deposit in The City of New York, selected by the
Calculation Agent, for negotiable certificates of deposit of major United States
money market 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 in a denomination of $5,000,000; provided, however,
                                                              --------  -------
that if fewer than three dealers selected as aforesaid by the Calculation Agent
are quoting as mentioned in this sentence, the CD Rate will be the CD Rate in
effect on such Interest Determination Date.

     Notwithstanding the foregoing, the interest rate hereon shall not be
greater than the Maximum Interest Rate, if any, or less than the Minimum
Interest Rate, if any, shown on the face hereof. The Calculation Agent shall
calculate the interest rate on this Security in accordance with the foregoing on
or before each Calculation Date and shall promptly thereafter notify the Company
and the Trustee of such interest rate. Any such calculation by the Calculation
Agent shall be conclusive and binding on the Company, the Trustee and the Holder
of this Security, absent manifest error.

     The Calculation Agent will, upon the request of the Holder of this
Security, provide to such Holder the interest rate hereon then in effect and, if
determined, the interest rate which will become effective as of the next
Interest Reset Date.

     If any Interest Payment Date specified on the face hereof would otherwise
be a day that is not a Business Day, the Interest Payment Date shall be
postponed to the next day that is a Business Day, except that if (i) the rate of
interest on this Security shall be determined in accordance with the provisions
of the heading "Determination of LIBOR" above and (ii) such Business Day is in
the next succeeding calendar month, such Interest Payment Date (other than an
Interest Payment Date at Maturity) shall be the immediately preceding Business
Day.

     The Interest Determination Date pertaining to an Interest Reset Date if the
rate of interest on the Security shall be determined in accordance with the
provisions of the

<PAGE>

                                                                              16

headings "Determination of Commercial Paper Rate", "Determination of Prime
Rate", "Determination of Federal Funds Rate" or "Determination of CD Rate" above
will be the second Business Day preceding such Interest Reset Date. The Interest
Determination Date pertaining to an Interest Reset Date if the rate of interest
on this Security shall be determined in accordance with the provisions of the
heading "Determination of LIBOR" above will be the second London Banking Day
preceding such Interest Reset Date. The Interest Determination Date pertaining
to an Interest Reset Date if the rate of interest on the Security shall be
determined in accordance with the provisions of the heading "Determination of
Treasury Rate" above (the "Treasury Interest Determination Date") will be the
day of the week in which such Interest Reset Date falls on which Treasury bills
would normally be auctioned. Treasury bills are usually sold at auction on the
Monday of each week, unless that day is a legal holiday, in which case the
auction is usually held on the following Tuesday, except that such auction may
be held on the preceding Friday. If, as a result of a legal holiday, an auction
is so held on the preceding Friday, such Friday will be the Treasury Interest
Determination Date pertaining to the Interest Reset Date occurring in the next
succeeding week. If an auction date shall fall on any Interest Reset Date for a
Treasury Rate Note, then such Interest Reset Date shall instead be the first
Business Day immediately following such auction date.

     The Calculation Date, if applicable, pertaining to any Interest
Determination Date shall be the first to occur of (a) the tenth calendar day
after the Interest Determination Date, or, if that day is not a Business Day,
the next succeeding Business Day or (b) the Business Day preceding the
applicable Interest Payment Date or Maturity of that Note, as the case may be.
However, LIBOR will be calculated on the LIBOR Interest Determination Date.

     Interest payments for this Security will include interest accrued to but
excluding the Interest Payment Date. Accrued interest hereon from and including
the Original Issue Date, or from but excluding the last date to which interest
hereon has been paid or duly provided for, as the case may be, will be an amount
calculated by multiplying the face amount hereof by an accrued interest factor.
Such accrued interest factor will be computed by adding the interest factor
calculated for each day from and including the Original Issue Date, or from but
excluding the last date to which interest shall have been paid or duly provided
for, as the case may be, to and including the date for which accrued interest is
being calculated. The interest factor

(expressed as a decimal rounded upwards, if necessary, to the next higher
one-hundred thousandth of a percentage point) for each such day will be computed
by dividing the interest rate (expressed as a decimal rounded upwards, if
necessary, to the next higher one-hundred thousandth of a percentage point)
applicable to such day by 360, in the case of the Commercial Paper Rate, the
Prime Rate, LIBOR, the Federal Funds Rate or the CD Rate, or by the actual
number of days in the year, in the case of the Treasury Rate. The interest
factor for Floating Rate Notes for which two or more interest rate formulae are
applicable will be calculated in the same manner as if only the lowest, highest
or average of, as the case may be, such interest rate formulae applied.

     Subject to a number of important qualifications and exceptions set forth in
the Indenture, the Indenture provides that neither the Company nor any
Subsidiary (as defined in the Indenture) will (i) issue, assume or guarantee any
notes, bonds, debentures or other similar evidences of indebtedness for money
borrowed secured by a mortgage, lien, pledge or other encumbrance upon any real
or personal property located in the continental United States of America without
effectively providing that the Securities will be secured equally and ratably
with (or, at the option of the Company, prior to) such indebtedness so long as
such indebtedness shall be so secured or (ii) enter into any Sale and Lease-Back
Transactions (as defined in the Indenture).

     The Indenture also provides that the Company at its option (a) will be
Discharged (as such term is defined in the Indenture) from any and all
obligations in respect of the Securities (except for certain obligations to
register the transfer or exchange of Securities, replace stolen, lost or
mutilated securities, maintain paying agencies and hold moneys for payment in
trust) or (b) need not comply with certain restrictive covenants of the
Indenture, if there is deposited with the Trustee, in the case of Securities
denominated in U.S. dollars, U.S. Government Obligations (as defined in the
Indenture) or, in the case of Securities denominated in a foreign currency,
Foreign Government Securities (as defined in the Indenture), which through the
payment of interest thereon and principal thereof in accordance with their terms
will provide money or a combination of money and U.S. Government Obligations or
Foreign Government Securities, as the case may be, in an amount sufficient to
pay in the currency, currencies or currency unit or units in which the
Securities are payable, all the principal, premium, if any, and interest on, the

                                                                              18

Securities on the dates such payments are in accordance with the terms of the
Securities.

     If an Event of Default 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 66 2/3% 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
or transfer hereof or in exchange herefor or in lieu hereof, whether or not
notation of such consent or waiver is made upon this Security.

     As set forth in, and subject to, the provisions of the Indenture, no Holder
of any Security of this series will have any right to institute any proceeding
with respect to the Indenture or for any remedy thereunder, unless such Holder
shall have previously given to the Trustee written notice of a continuing Event
of Default with respect to this series, the Holders of not less than 25% in
principal amount of the Outstanding Securities of this series shall have made
written request, and offered reasonable indemnity, to the Trustee to institute
such proceeding as trustee, the Trustee shall not have received from the Holders
of a majority in principal amount of the Outstanding Securities of this series a
direction inconsistent with such request and the Trustee shall have failed to
institute such proceeding within 60 days; provided, however, that such
                                          --------  -------
limitations do not apply to a suit instituted by the Holder hereof for the
enforcement of payment of the principal, premium, if any, or interest on this
Security on or after the respective due dates expressed herein.

                                                                              19

     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, premium, if any, and interest
on this Security at the times, places and rate, and in the coin or currency,
herein prescribed.

     As provided in the Indenture and subject to certain limitations therein set
forth, the transfer of this Security is registrable in the Security Register,
upon surrender of this Security for registration of transfer at the corporate
trust office of the Trustee or such other office or agency as may be designated
by the Company in Cincinnati, Ohio, duly endorsed by, or accompanied by a
written instrument of transfer in form satisfactory to the Company and the
Security Registrar duly executed by, the Holder hereof or his attorney duly
authorized in writing, and thereupon one or more new Securities of this Series
and of like tenor, of authorized denominations and with like terms and
conditions and for the same aggregate principal amount will be issued to the
designated transferee or transferees.

     The Securities of this series are issuable only in registered form, without
coupons, in denominations of $1,000 and any integral multiple of $1,000 in
excess thereof. As provided in the Indenture and subject to certain limitations
therein set forth, Securities of this series are exchangeable for a like
aggregate principal amount of Securities of this series and of like tenor of a
different authorized denomination and with like terms and conditions, as
requested by the Holder surrendering the same.

     No service charge shall be made for any such registration of transfer or
exchange, but the Company may require payment of a sum sufficient to cover any
tax or other governmental charge payable in connection therewith.

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

     The Indenture and the Securities shall be governed by and construed in
accordance with the laws of the State of New York.
