principal thereof is paid or made available for payment.

      The Notes are not subject to any sinking fund.

                                       4

Indenture.

Notes, whether Initial Notes, Exchange Notes or additional Notes issued under
Section 2.02(a) shall constitute one series of Notes and shall vote together as
one series of Notes.

      (a) The Notes shall be substantially in the forms of Exhibit A hereto. The
terms and provisions contained in the form of Notes set forth in Exhibit A shall

supplemented by this Supplemental Indenture.

                                       5
<PAGE>

      Any of the Notes may have such letters, numbers or other marks of
identification and such notations, legends, endorsements or changes as the
officers executing the same may approve (execution thereof to be conclusive
evidence of such approval) and as are not inconsistent with the provisions of
the Indenture as supplemented by this Supplemental Indenture, or as may be
required by the Depository or as may be required for the Initial Notes to be
tradeable on any market developed for trading of securities pursuant to Rule
144A or as may be required to comply with any applicable law or with any rule or
regulation made pursuant thereto or with any rule or regulation of any
securities exchange or automated quotation system on which the Notes may be
listed, or to conform to usage, or to indicate any special limitations or
restrictions to which any particular Notes are subject.

      (b) So long as any Notes of this series are eligible for book-entry
settlement with the Depository, or unless otherwise required by law, or
otherwise contemplated by Section 2.05(b), all of the Notes of this series shall
be represented by one or more Notes in global form registered in the name of the
Depository or the nominee of the Depository (each and collectively, the "GLOBAL
NOTE"). The transfer and exchange of beneficial interests in any such Global
Note shall be effected through the Depository in accordance with the Indenture
and the applicable procedures of the Depository. Except as provided in Section
2.05(b), beneficial owners of a Global Note shall not be entitled to have
certificates registered in their names, will not receive or be entitled to
receive physical delivery of certificates in definitive form and will not be
considered holders of such Global Note.

      Any Global Note shall represent such of the outstanding Notes of a series
as shall be specified therein and shall provide that it shall represent the
aggregate amount of outstanding Notes of that series from time to time endorsed
thereon and that the aggregate amount of outstanding Notes represented thereby
may from time to time be increased or reduced to reflect redemptions, transfers
or exchanges permitted hereby. Any endorsement of a Global Note to reflect the
amount of any increase or decrease in the amount of outstanding Notes
represented thereby shall be made by the Trustee in such manner and upon
instructions given by the holder of such Notes in accordance with the Indenture.
Payment of principal of and interest and premium, if any, on any Global Note
shall be made to the holder of such Note.

      SECTION 2.04. Restrictive Legends. (a) Except as otherwise provided in
paragraph (c), each Initial Note shall bear the following legend on the face
thereof:

THIS NOTE HAS NOT BEEN REGISTERED UNDER THE SECURITIES ACT OF 1933, AS AMENDED
(THE "SECURITIES ACT"), OR ANY STATE OR OTHER SECURITIES LAWS. NEITHER THIS NOTE
NOR ANY INTEREST OR PARTICIPATION HEREIN MAY BE REOFFERED, SOLD, ASSIGNED,

                                       6
<PAGE>

TRANSFERRED, PLEDGED, ENCUMBERED OR OTHERWISE DISPOSED OF IN THE ABSENCE OF SUCH
REGISTRATION OR UNLESS SUCH TRANSACTION IS EXEMPT FROM, OR NOT SUBJECT TO, THE
REGISTRATION REQUIREMENTS OF THE SECURITIES ACT. BY ITS ACQUISITION HEREOF, THE
HOLDER (1) REPRESENTS THAT IT IS A "QUALIFIED INSTITUTIONAL BUYER" (AS DEFINED
IN RULE 144A UNDER THE SECURITIES ACT ("RULE 144A")), (2) AGREES NOT TO OFFER,
SELL OR OTHERWISE TRANSFER SUCH NOTE PRIOR TO THE DATE WHICH IS THE LATER OF (X)
TWO YEARS (OR SUCH SHORTER PERIOD OF TIME AS PERMITTED BY RULE 144(k) OF THE
SECURITIES ACT) AFTER THE LATER OF THE LAST DATE OF ISSUANCE OF ANY NOTE OF THIS
SERIES (OR ANY PREDECESSOR OF THIS NOTE) AND THE LAST DATE ON WHICH CINCINNATI
FINANCIAL CORPORATION OR ANY AFFILIATE OF CINCINNATI FINANCIAL CORPORATION WAS
THE OWNER OF THIS NOTE (OR ANY PREDECESSOR OF THIS NOTE) AND (Y) SUCH LATER
DATE, IF ANY, AS MAY BE REQUIRED BY APPLICABLE LAW (THE "RESALE RESTRICTION
TERMINATION DATE") EXCEPT (A) TO CINCINNATI FINANCIAL CORPORATION OR ANY
SUBSIDIARY THEREOF, (B) PURSUANT TO A REGISTRATION STATEMENT WHICH HAS BEEN
DECLARED EFFECTIVE UNDER THE SECURITIES ACT, (C) FOR SO LONG AS THE NOTES ARE
ELIGIBLE FOR RESALE PURSUANT TO RULE 144A, TO A PERSON IT REASONABLY BELIEVES IS
A "QUALIFIED INSTITUTIONAL BUYER" AS DEFINED IN RULE 144A THAT PURCHASES FOR ITS
OWN ACCOUNT OR FOR THE ACCOUNT OF A QUALIFIED INSTITUTIONAL BUYER TO WHOM NOTICE
IS GIVEN THAT THE TRANSFER IS BEING MADE IN RELIANCE ON RULE 144A, OR (D)
PURSUANT TO ANOTHER AVAILABLE EXEMPTION FROM THE REGISTRATION REQUIREMENTS OF
THE SECURITIES ACT AND (3) AGREES THAT IT WILL GIVE TO EACH PERSON TO WHOM THIS
NOTE IS TRANSFERRED A NOTICE SUBSTANTIALLY TO THE EFFECT OF THIS LEGEND;
PROVIDED THAT CINCINNATI FINANCIAL CORPORATION, THE TRUSTEE, THE TRANSFER AGENT
AND THE REGISTRAR WILL HAVE THE RIGHT PRIOR TO ANY SUCH OFFER, SALE OR TRANSFER
(I) PURSUANT TO CLAUSE (D)TO REQUIRE THE DELIVERY OF AN OPINION OF COUNSEL,
CERTIFICATION AND/OR OTHER INFORMATION REASONABLY SATISFACTORY TO EACH OF THEM,
AND (II) IN EACH OF THE FOREGOING CASES, TO REQUIRE THAT A CERTIFICATE OF
TRANSFER IN THE FORM APPEARING ON THE OTHER SIDE OF THIS NOTE IS COMPLETED AND
DELIVERED BY THE TRANSFEROR TO CINCINNATI FINANCIAL CORPORATION AND THE TRUSTEE.
THIS LEGEND WILL BE REMOVED UPON THE REQUEST OF THE HOLDER AFTER THE RESALE
RESTRICTION TERMINATION DATE.

      (b) Each Global Note shall also bear the following legend on the face
thereof:

                                       7
<PAGE>

THIS NOTE IS A GLOBAL NOTE WITHIN THE MEANING OF THE INDENTURE HEREAFTER
REFERRED TO AND IS REGISTERED IN THE NAME OF THE DEPOSITORY OR A NOMINEE
THEREOF. UNLESS AND UNTIL IT IS EXCHANGED IN WHOLE OR IN PART FOR NOTES IN
DEFINITIVE FORM, THIS NOTE MAY NOT BE TRANSFERRED EXCEPT AS A WHOLE BY THE
DEPOSITORY TO A NOMINEE OF THE DEPOSITORY OR BY A NOMINEE OF THE DEPOSITORY TO
THE DEPOSITORY OR ANOTHER NOMINEE OF THE DEPOSITORY OR BY THE DEPOSITORY OR ANY
SUCH NOMINEE TO A SUCCESSOR DEPOSITORY OR A NOMINEE OF SUCH SUCCESSOR
DEPOSITORY.

      Each Global Note for which the Depository Trust Company is the Depository
shall also bear the following legend on the face thereof:

UNLESS THIS CERTIFICATE IS PRESENTED BY AN AUTHORIZED REPRESENTATIVE OF THE
DEPOSITORY TRUST COMPANY, A NEW YORK CORPORATION ("DTC") TO THE COMPANY OR ITS
AGENT FOR REGISTRATION OF TRANSFER, EXCHANGE OR PAYMENT, AND ANY CERTIFICATE
ISSUED IS REGISTERED IN THE NAME OF CEDE & CO. OR SUCH OTHER NAME AS REQUESTED
BY AN AUTHORIZED REPRESENTATIVE OF DTC (AND ANY PAYMENT IS MADE TO CEDE & CO. OR
TO SUCH OTHER ENTITY AS IS REQUIRED BY AN AUTHORIZED REPRESENTATIVE OF DTC), ANY
TRANSFER, PLEDGE OR OTHER USE HEREOF FOR VALUE OR OTHERWISE BY OR TO ANY PERSON
IS WRONGFUL SINCE THE REGISTERED OWNER HEREOF, CEDE & CO., HAS AN INTEREST
HEREIN.

      (c) (i) If the Company determines (upon the advice of counsel and such
other certifications and evidence as the Company may reasonably require) that
any Note is eligible for resale pursuant to Rule 144(k) under the Securities Act
(or a successor provision) and that the Restricted Legend is no longer necessary
or appropriate in order to ensure that subsequent transfers of such Note (or a
beneficial interest therein) are effected in compliance with the Securities Act,
or

      (ii) after an Initial Note is (x) sold pursuant to an effective
registration statement under the Securities Act, pursuant to the Registration
Rights Agreement or otherwise, or (y) exchanged for an Exchange Note,

the Company may instruct the Trustee to cancel such Note and issue to the Holder
thereof (or to its transferee) a new Note of like tenor and amount, registered
in the name of the Holder thereof (or its transferee), that does not bear the
Restricted Legend, and the Trustee will comply with such instruction. If a Note
to be reissued under this Section 2.04(c) without a Restricted Legend is
represented by a Global Note bearing the Restricted Legend, the principal amount
of the legended Global Note shall be reduced by the principal amount of the Note
to be

                                       8
<PAGE>

reissued without the Restricted Legend and the principal amount of a Global Note
without the Restricted Legend of the appropriate series of Notes shall be
increased by an equal principal amount. If a Global Note without the Restricted
Legend of the appropriate series of Notes is not then outstanding, the Company
shall execute and the Trustee shall authenticate and deliver a Global Note of
the appropriate series of Notes without the Restricted Legend to the Depository.

      SECTION 2.05. Transfer Restrictions. (a) By its acceptance of any Note
bearing the Restricted Legend, each Holder of such a Note acknowledges the
restrictions on transfer of such Note set forth in this Supplemental Indenture
and in the Restricted Legend and agrees that it will transfer such Note only as
provided in this Supplemental Indenture and the Restricted Legend. The Company
and the Trustee as Securities registrar shall not register a transfer of any
Note unless such transfer complies with the restrictions on transfer of such
Note set forth in this Supplemental Indenture and the Restricted Legend. In
connection with any transfer of Notes, each Holder agrees by its acceptance of
the Notes to furnish the Trustee as Security registrar or the Company such
certifications, legal opinions or other information as either of them may
reasonably require to confirm that such transfer is being made pursuant to an
exemption from, or a transaction not subject to, the registration requirements
of the Securities Act; provided that the Trustee shall not be required to
determine (but may rely on a determination made by the Company with respect to)
the sufficiency of any such certifications, legal opinions or other information.

      The Trustee shall retain copies of all letters, notices and other written
communications received pursuant to the Indenture or this Section 2.05(a). The
Company shall have the right to inspect and make copies of all such letters,
notices or other written communications at any reasonable time upon the giving
of reasonable written notice to the Trustee.

      The Trustee shall have no obligation or duty to monitor, determine or
inquire as to compliance with any restrictions on transfer imposed under this
Supplemental Indenture or under applicable law with respect to any transfer of
any interest in any Security (including any transfers between or among members
of, or participants in, the Depository or beneficial owners of interests in any
Global Note) other than to require delivery of such certificates and other
documentation or evidence as are expressly required by, and to do so if and when
expressly required by the terms of, this Supplemental Indenture, and to examine
the same to determine substantial compliance as to form with the express
requirements hereof.

      (b) The following provisions shall apply only to Global Notes:

            (i) Each Global Note authenticated under this Supplemental Indenture
      shall be registered in the name of the Depository or a nominee thereof and
      delivered to such Depository or a nominee thereof or the

                                       9
<PAGE>

      Trustee if the Trustee is acting as custodian for the Depository or its
      nominee with respect to such Global Note, and each such Global Note shall
      constitute a single Security for all purposes of the Indenture and this
      Supplemental Indenture.

            (ii) Notwithstanding any other provision in the Indenture, as
      supplemented by this Supplemental Indenture, no Global Note may be
      exchanged in whole or in part for Notes registered, and no transfer of a
      Global Note in whole or in part may be registered, in the name of any
      Person other than the Depository or a nominee thereof unless (A) the
      Depository (x) has notified the Company that it is unwilling or unable to
      continue as Depository for such Global Note or (y) has ceased to be a
      clearing agency registered under the Securities Exchange Act of 1934, (B)
      an Event of Default has occurred and is continuing with respect to the
      Notes or (C) the Company, in its sole discretion, notifies the Trustee in
      writing that it no longer wishes to have the Notes represented by a Global
      Note. Any Global Note exchanged pursuant to clause (A) or (B) above shall
      be so exchanged in whole and not in part and any Global Note exchanged
      pursuant to clause (C) above may be exchanged in whole or from time to
      time in part as directed by the Company. Any Note issued in exchange for a
      Global Note or any portion thereof shall be a Global Note; provided that
      any such Note so issued that is registered in the name of a Person other
      than the Depository or a nominee thereof shall not be a Global Note.

            (iii) Notes issued in exchange for a Global Note or any portion
      thereof pursuant to clause (ii) above shall be issued in definitive, fully
      registered form, without interest coupons, shall have an aggregate
      principal amount equal to that of such Global Note or portion thereof to
      be so exchanged, shall be registered in such names and be in such
      authorized denominations as the Depository shall designate and shall bear
      any legends required hereunder. Any Global Note to be exchanged in whole
      shall be surrendered by the Depository to the Trustee, as Securities
      registrar. With regard to any Global Note to be exchanged in part, either
      such Global Note shall be so surrendered for exchange or, if the Trustee
      is acting as custodian for the Depository or its nominee with respect to
      such Global Note, the principal amount thereof shall be reduced, by an
      amount equal to the portion thereof to be so exchanged, by means of an
      appropriate adjustment made on the records of the Trustee. Upon any such
      surrender or adjustment, the Trustee shall authenticate and make available
      for delivery the Note issuable on such exchange to or upon the written
      order of the Depository or an authorized representative thereof.

            (iv) In the event of the occurrence of any of the events specified
      in clause (ii) above, the Company will promptly make available to the

                                       10
<PAGE>

      Trustee a reasonable supply of certificated Notes in definitive, fully
      registered form, without interest coupons.

            (v) Neither any members of, or participants in, the Depository
      ("AGENT MEMBERS") nor any other Persons on whose behalf Agent Members may
      act shall have any rights under the Indenture as supplemented by this
      Supplemental Indenture with respect to any Global Notes registered in the
      name of the Depository or any nominee thereof, and the Depository or such
      nominee, as the case may be, may be treated by the Company, the Trustee
      and any agent of the Company or the Trustee as the absolute owner and
      holder of such Global Notes for all purposes whatsoever. Notwithstanding
      the foregoing, nothing herein shall prevent the Company, the Trustee or
      any agent of the Company or the Trustee from giving effect to any written
      certification, proxy or other authorization furnished by the Depository or
      such nominee, as the case may be, or impair, as between the Depository,
      its Agent Members and any other Person on whose behalf an Agent Member may
      act, the operation of customary practices of such Persons governing the
      exercise of the rights of a holder of any Note.

            (vi) At such time as all interests in a Global Note have been
      redeemed, repurchased, converted, canceled or exchanged for Notes in
      certificated form, such Global Note shall, upon receipt thereof, be
      canceled by the Trustee in accordance with standing procedures and
      instructions existing between the Depository and the Trustee. At any time
      prior to such cancellation, if any interest in a Global Note is redeemed,
      repurchased, converted, canceled or exchanged for Notes in certificated
      form, the principal amount of such Global Note shall, in accordance with
      the standing procedures and instructions existing between the Depository
      and the Trustee, be appropriately reduced, and an endorsement shall be
      made on such Global Note, by the Trustee, at the direction of the Trustee,
      to reflect such reduction.

      Section 2.06. Additional Interest.

      If a Registration Default (as defined in the Registration Rights
Agreement) occurs with respect to any Notes of this series, the interest rate
borne by such Notes shall be increased as provided in the Registration Rights
Agreement.

      Additional Interest (as defined in the Registration Rights Agreement)
shall, for the purposes of the Notes, constitute "INTEREST" used in Article Four
of the Indenture and interest for purposes of this Supplemental Indenture and
Global Note.

                             REDEMPTION OF THE NOTES

      Section 3.01 . Optional Redemption by Company. The Company may redeem the
Notes, at any time in whole and from time to time in part, at the option of the
Company, prior to the Stated Maturity at a redemption price (the "REDEMPTION
PRICE") equal to the greater of (i) 100% of the principal amount of such Notes
and (ii) the sum of the present values of the remaining scheduled payments of
principal and interest thereon (exclusive of interest accrued but not paid to
the Redemption Date (as defined below)) discounted to the redemption date on a
semiannual basis (assuming a 360-day year consisting of twelve 30-day months) at
the Treasury Rate plus 15 basis points, plus in each case accrued interest
thereon but not paid to the Redemption Date.

      Except as set forth above, the Securities will not be redeemable by the
Company prior to maturity.

      The Company shall give notice to the Trustee of any redemption specifying
the date of such redemption by Company Order at least 30 days but not more than
60 days before the date such Notes are to be redeemed (each, a "REDEMPTION
DATE").

      Unless the Company defaults in payment of the Redemption Price, on and
after any Redemption Date interest will cease to accrue on the Notes or portions
thereof called for redemption.

      The Company shall pay interest to a Person other than the Holder of record
on the Regular Record Date if the Company elects to redeem the Notes on a date
that is after a Regular Record Date but on or prior to the corresponding
Interest Payment Date. In this instance, the Company shall pay accrued interest
on the Notes being redeemed to, but not including, the Redemption Date to the
same Person to whom the Company shall pay the Redemption Price of those Notes.

      The Notes are not subject to any sinking fund.

      Section 3.02. Selection of Notes to Be Redeemed. If less than all of the
Notes are to be redeemed, unless the procedures of the Depositary provide
otherwise, the Trustee shall select the Notes to be redeemed by lot, on a pro
rata basis or by another method the Trustee considers fair and appropriate (so
long as such method is not prohibited by the rules of any stock exchange or
quotation association on which the Notes are then traded or quoted). Subject to
the previous sentence, the Trustee shall make the selection within five Business
Days after it receives the notice provided for in Section 3.01 from outstanding
Notes not previously called for redemption. The Trustee may select for
redemption portions of the principal amount of Notes that have denominations
larger than $1,000.

                                       12
<PAGE>

      Notes and portions of Notes that the Trustee selects shall be in principal
amounts of $1,000 or an integral multiple of $1,000. Provisions of this
Supplemental Indenture that apply to Notes called for redemption also apply to
portions of Notes called for redemption. The Trustee shall notify the Company
promptly of the Notes or portions of the Notes to be redeemed.

      Section 3.03. Redemption Notice. At least 30 days but not more than 60
days before a Redemption Date, the Company shall mail a notice of redemption (a
"REDEMPTION NOTICE") by first-class mail, postage prepaid, to each Holder of
Notes to be redeemed.

      The notice shall identify the Notes to be redeemed and shall state:

      (1)   the Redemption Date;

      (2)   the Redemption Price;

      (3)   the name and address of the Paying Agent;

      (4)   that Notes called for redemption will be redeemed on the Redemption
            Date;

      (5)   that Notes called for redemption must be surrendered to the Paying
            Agent to collect the Redemption Price;

      (6)   if fewer than all of the outstanding Notes are to be redeemed, the
            certificate numbers, if any, and principal amounts of the particular
            Notes to be redeemed;

      (7)   that, unless the Company defaults in making payment of such
            Redemption Price, interest and Additional Interest, if any, on Notes
            called for redemption will cease to accrue on and after the
            Redemption Date; and

      (8)   the CUSIP number(s) of the Notes.

      At the Company's request, the Trustee shall give the Redemption Notice in
the Company's name and at the Company's expense; provided that the Company makes
such request at least seven Business Days prior to the date by which such
Redemption Notice must be given to Holders in accordance with this Section 3.03
and the text of such notice is completed by the Company.

      Section 3.04. Effect of Redemption Notice. Once the Redemption Notice is
given, Notes called for redemption become due and payable on the Redemption Date
and at the Redemption Price stated in the notice. Upon surrender to the Paying
Agent, such Notes shall be paid at the Redemption Price stated in the notice.

                                       13
<PAGE>

      Section 3.05. Deposit of Redemption Price. Prior to 11:00 a.m., New York
City time, on the Redemption Date, the Company shall deposit with the Paying
Agent money sufficient to pay the Redemption Price of all Notes to be redeemed
on that date other than Notes or portions of Notes called for redemption which
on or prior thereto have been delivered by the Company to the Trustee for
cancellation. If such money is then held by the Company in trust and is not
required for such purpose it shall be discharged from such trust.

      Section 3.06. Securities Redeemed in Part. Upon surrender of a Note that
is redeemed in part, the Company shall execute and the Trustee shall
authenticate and deliver to the Holder a new Note in an authorized denomination
equal in principal amount to the unredeemed portion of the Security surrendered.

                                   ARTICLE 4
                                   DEFEASANCE

      Section 4.01. Defeasance By The Company. The Notes shall be subject to
defeasance at the option of the Company in accordance with the terms and
conditions set forth in Article 11 of the Indenture.

                                   ARTICLE 5
                                  MISCELLANEOUS

      Section 5.01. Rule 144A Information; No Resales By Affiliates. (a) Within
the period prior to the expiration of the holding period applicable to sales
thereof under Rule 144(k) under the Securities Act (or any successor provision),
the Company covenants and agrees that it shall, during any period in which it is
not subject to Section 13 or 15(d) under the Securities Exchange Act of 1934,
make available to any Holder or beneficial Holder of Initial Notes in connection
with any sale thereof and any prospective purchaser of Initial Notes designated
by such Holder or beneficial Holder, the information required pursuant to Rule
144A(d)(4) under the Securities Act upon the request of any Holder or beneficial
Holder of the Initial Notes and it will take such further action as any Holder
or beneficial Holder of such Initial Notes may reasonably request, all to the
extent required from time to time to enable such Holder or beneficial Holder to
sell its Initial Notes without registration under the Securities Act within the
limitation of the exemption provided by Rule 144A, as such Rule may be amended
from time to time. Upon the request of any Holder or any beneficial Holder of
the Initial Notes, the Company will deliver to such Holder a written statement
as to whether it has complied with such requirements.

      (b) Any Initial Notes that, prior to the expiration of the holding period
applicable to sales thereof under Rule 144(k) under the Securities Act (or any
successor provision), are purchased or owned by the Company or any affiliate

                                       14
<PAGE>

thereof (within the meaning of Rule 144) that is controlled by the Company may
not be resold by the Company or such affiliate unless registered under the
Securities Act or resold pursuant to an exemption from the registration
requirements of the Securities Act in a transaction which results in such
Initial Notes no longer being "RESTRICTED SECURITIES" (as defined under Rule
144).

      Section 5.02. Ratification Of Indenture.

      The Indenture, as supplemented by this Supplemental Indenture, is in all
respects ratified and confirmed, and this Supplemental Indenture shall be deemed
part of the Indenture in the manner and to the extent herein and therein
provided.

      Section 5.03. Trustee Not Responsible For Recitals.

      The recitals herein contained are made by the Company and not by the
Trustee, and the Trustee assumes no responsibility for the correctness thereof.
The Trustee makes no representation as to the validity or sufficiency of this

      Section 5.04. Governing Law.

      This Supplemental Indenture and each Note shall be governed by and
construed in accordance with the laws of the State of New York without regard to
the principles of conflicts of laws thereof.

      Section 5.05. Separability.

      In case any one or more of the provisions contained in this Supplemental
Indenture or in the Notes shall for any reason be held to be invalid, illegal or
unenforceable in any respect, such invalidity, illegality or unenforceability
shall not affect any other provisions of this Supplemental Indenture or of the
Notes, but this Supplemental Indenture and the Notes shall be construed as if
such invalid or illegal or unenforceable provision had never been contained
herein or therein.

      Section 5.06. Counterparts.

      This Supplemental Indenture may be executed in any number of counterparts
each of which shall be an original; but such counterparts shall together
constitute but one and the same instrument.

                          6.125% Senior Notes Due 2034

No. 1
$375,000,000

      CINCINNATI FINANCIAL CORPORATION, a corporation duly organized and
existing under the laws of Ohio (herein called the "COMPANY", which term
includes any successor Person under the Indenture referred to herein), for value
received, hereby promises to pay to CEDE & Co., or registered assigns, the
principal sum of THREE HUNDRED SEVENTY FIVE MILLION DOLLARS ($375,000,000) on
November 1, 2034, and to pay interest thereon from November 1, 2004, or from the
most recent Interest Payment Date to which interest has been paid or duly
provided for, semiannually in arrears on May 1 and November 1 in each year
commencing May 1, 2005, at the rate of 6.125% per annum, until the principal
hereof is paid or made available for payment. 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 Note (or
one or more predecessor Notes) is registered at the close of business on the
Regular Record Date for such interest, which shall be the April 15 or October 15
(whether or not a Business Day), as the case may be, next preceding such
Interest Payment Date; provided, however, that interest at Stated Maturity will
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 Note (or one
or more predecessor Notes) 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 Notes 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 Notes 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 of and interest on this Note will be made at
the Place of Payment which, subject to the right of the Company to vary or
terminate the appointment of such agency, shall initially be the principal
office of the Trustee, 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 may be made by check mailed to the address of the Person entitled
thereto as such address shall appear in the Security Register.

                              6.125% Notes Due 2034

      This Note is one of a duly authorized issue of Securities of the Company
(herein called the "NOTES"), issued and to be issued in one or more series under
the Indenture, dated as of November 1, 2004 and the Supplemental Indenture,
dated as of November 1, 2004 (collectively herein called the "INDENTURE"),
between the Company and The Bank of New York Trust Company, N.A. (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 Notes
and of the terms upon which the Notes are, and are to be, authenticated and
delivered. This Note is one of the Notes of the series designated herein,
limited in aggregate principal amount to $375,000,000.

      The Notes are redeemable, at any time in whole and from time to time in
part, at the option of the Company, prior to the Stated Maturity at the
Redemption Price and on any Redemption Date as provided in the Indenture.

      This Note is not subject to any sinking fund.

      As provided in the Indenture, defeasance may occur at any time of (a) the
entire indebtedness of the Company on this Note and (b) certain restrictive
covenants and the related defaults and Events of Default, upon compliance by the
Company with certain conditions set forth therein, which provisions apply to
this Note.

      If an Event of Default with respect to Notes of this series shall occur
and be continuing, the principal of the Notes 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
(including these Notes) to be affected under the Indenture at any time by the
Company and the Trustee with the consent of the Holders of greater than 50% in
principal amount of the Securities at the time Outstanding of each series
affected. The Indenture also contains provisions permitting the Holders of
specified percentages in principal amount of the Securities at the time
Outstanding of each series affected, 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

                                      A2-1
<PAGE>

waiver by the Holder of this Note shall be conclusive and binding upon such
Holder and upon all future Holders of this Note and of any Note 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 Note.

      As set forth in, and subject to, the provisions of the Indenture, no
Holder of any Note 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 such Security, the Holders of not less than 25% in principal
amount of the Outstanding Notes shall have made written request, and offered
indemnity, to the Trustee to institute such proceeding as trustee, and the
Trustee shall not have received from the Holders of a majority in principal
amount of the Outstanding Notes a direction inconsistent with such request and
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 of or interest on this
Note on or after the respective due dates expressed herein.

      No reference herein to the Indenture and no provision of this Note or of
the Indenture shall alter or impair the obligation of the Company, which is
absolute and unconditional, to pay the principal of and interest on this Note at
the times, places, and rate, and in the coin or currency, herein prescribed.

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
Note shall be exchangeable for definitive Notes in registered form and so
notifies the Trustee or (z) an Event of Default has occurred and is continuing;

Notes of this series in definitive registered form will be issued in exchange
for this Global Note, or any portion hereof, only if such Notes in definitive
