ITEM 1.01. ENTRY INTO A MATERIAL DEFINITIVE AGREEMENT.

ITEM 2.03. CREATION OF A DIRECT FINANCIAL OBLIGATION OR AN OBLIGATION UNDER AN OFF-BALANCE SHEET ARRANGEMENT OF A REGISTRANT.

On May 9, 2005, Cincinnati Financial Corporation (company) entered into a second supplemental indenture (second supplemental indenture), dated as of May 9, 2005, with The Bank of New York Trust Company, N.A. (trustee), which supplemented an indenture (base indenture), dated November 1, 2004, by and between the company and the trustee (together with the second supplemental indenture, the indenture).

The indenture provides for the issuance of $392,249,000 aggregate principal amount of 6.92% senior debentures due 2028 (exchange debentures). Interest is payable on the exchange debentures on each May 15 and November 15 commencing on May 15, 2005. The exchange debentures were issued pursuant to a registration statement that has been filed with the SEC and was declared effective on March 30, 2005.

The exchange debentures are not redeemable prior to maturity.

Under the prospectus, dated April 1, 2005, an event of default is defined as (i) default for 30 days in payment of any interest on the exchange debentures; (ii) failure to pay principal and premium, if any, when due; (iii) failure to observe or perform any other covenant in the indenture or exchange debentures


(except a covenant or warranty whose breach or default in performance is specifically listed as an events of default), if such failure continues for 30 days after written notice by the trustee or the holders of at least 25 percent in aggregate principal amount of the exchange debentures then outstanding; (iv) uncured or unwaived failure to pay principal of or interest on any other obligation for borrowed money beyond any period of grace if (a) the aggregate principal amount of any such obligation is in excess of $50 million and (b) the company is not contesting the default in such payment in good faith and by appropriate proceedings; or (v) certain events of bankruptcy, insolvency, receivership or reorganization.

The above description of the indenture does not purport to be a complete statement of the parties' rights and obligations under the indenture and the transactions contemplated by the indenture. The above description is qualified in its entirety by reference to the indenture. A copy of the second supplemental indenture is attached to this Current Report on Form 8-K as Exhibit 4.1 and a copy of the base indenture has been previously filed as Exhibit 4.1 to the company's Form 8-K dated November 2, 2004. The base indenture and the second supplemental indenture are each incorporated herein by reference.

ITEM 8.01. OTHER EVENTS.

On April 29, 2005, the company completed its previously announced offer to exchange its outstanding 6.90% senior debentures due 2028 (old debentures) for up to $420 million aggregate principal amount of newly issued exchange debentures (exchange offer). Additionally, the company completed its offer to repurchase up to $420 million aggregate principal amount of old debentures at a price of $999.03 per $1,000 principal amount, which represents the original price of the old debentures, plus interest (rescission offer).

WHEREAS, the Company executed and delivered a Supplemental Indenture dated as of November 1, 2004 (the "FIRST SUPPLEMENTAL INDENTURE" and the 2004 Indenture as supplemented by the First Supplemental Indenture and by this Second Supplemental Indenture, the "INDENTURE") to the Trustee in connection with the issuance of the Company's 6.125% senior notes due 2034, a series of securities under the Indenture;

WHEREAS, the Board of Directors of the Company has duly adopted resolutions authorizing the Company to execute and deliver this Second Supplemental Indenture;

Their Stated Maturity shall be May 15, 2028 and they shall bear interest at the rate of 6.92% per annum from the Issue Date or from the most recent Interest Payment Date to which interest has been paid or duly provided for, as the case may be, payable semi-annually in arrears on each May 15 and November 15 (each, an Interest Payment Date), commencing May 15, 2005, until the principal thereof is paid or made available for payment.

The 6.92% Notes are not subject to any sinking fund. The 6.92% Notes may not be redeemed prior to the Stated Maturity.

Interest on the 6.92% Notes shall be computed on the basis of a 360 day year comprised of twelve 30 day months.

(b) The 6.92% Notes shall be issuable in registered form without coupons in denominations of $1,000 and any integral multiple thereof.

2

(c) The principal of, premium, if any, and interest on the 6.92% Notes shall be payable at the office or agency of the Company designated for that purpose as the Place of Payment, as provided in Section 4.02 of the Indenture; provided, however, that interest may be payable at the option of the Company by check mailed to the address of the Person entitled thereto as such address shall appear on the Security Register on the record date for such interest payment.

Section 2.02. Principal Amount. The 6.92% Notes shall be limited to an aggregate principal amount of $392,249,000, except for 6.92% Notes authenticated and delivered upon registration of transfer of, or in exchange for, or in lieu of, other Securities of this same series pursuant to Sections 3.02, 3.03, 3.04 or 10.02 of the Indenture.

Section 2.03. Form of Securities; Global Form.

(a) The 6.92% Notes shall be substantially in the forms of Exhibit A hereto. The terms and provisions contained in the form of 6.92% Notes set forth in Exhibit A shall constitute, and are hereby expressly made, a part of the Indenture as supplemented by this Second Supplemental Indenture.

Any of the 6.92% 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, or as may be required by the Depository 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 6.92% Notes may be listed, or to conform to usage, or to indicate any special limitations or restrictions to which any particular 6.92% Notes are subject.

(b) So long as any 6.92% Notes 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 6.92% Notes of this series shall be represented by one or more 6.92% 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, 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 6.92% Notes as shall be specified therein and shall provide that it shall represent the aggregate amount of outstanding 6.92% Notes from time to time endorsed thereon and that the aggregate amount of outstanding 6.92% Notes represented thereby may from

3

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 6.92% Notes represented thereby shall be made by the Trustee in such manner and upon instructions given by the Holder of such 6.92% 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. Each Global Note shall bear the following legend on the face thereof:

THIS 6.92% 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 6.92% 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.

Section 2.05. Transfer Restrictions.

(a) 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

4

expressly required by the terms of, this Second 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 Second 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 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 Second Supplemental Indenture.

(ii) Notwithstanding any other provision in the Indenture, no Global Note may be exchanged in whole or in part for 6.92% 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 6.92% Notes or (C) the Company, in its sole discretion, notifies the Trustee in writing that it no longer wishes to have the 6.92% 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 6.92% Note issued in exchange for a Global Note or any portion thereof shall be a Global Note; provided that any such 6.92% 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) 6.92% 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

5

such surrender or adjustment, the Trustee shall authenticate and make available for delivery the 6.92% 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 Trustee a reasonable supply of certificated 6.92% 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 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 6.92% Note.

(vi) At such time as all interests in a Global Note have been redeemed, repurchased, converted, canceled or exchanged for 6.92% 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 6.92% 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.

ARTICLE 3

DEFEASANCE

Section 4.02. 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 Second Supplemental Indenture.

This Second Supplemental Indenture and each 6.92% 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 4.04. Separability.

In case any one or more of the provisions contained in this Second Supplemental Indenture or in the 6.92% 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 Second Supplemental Indenture or of the 6.92% Notes, but this Second Supplemental Indenture and the 6.92% Notes shall be construed as if such invalid or illegal or unenforceable provision had never been contained herein or therein.

Section 4.05. Counterparts.

This Second 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.
