            This GUARANTEE AGREEMENT (the "Common Securities Guarantee"), dated
as of November [ ], 2001, is executed and delivered by The St. Paul Companies,
Inc., a Minnesota corporation (the "Guarantor"), for the benefit of the Holders
(as defined herein) from time to time of the Common Securities (as defined
herein) of St. Paul Capital Trust I, a Delaware business trust (the "Issuer").

            WHEREAS, pursuant to an Amended and Restated Declaration of Trust
(the "Declaration"), dated as of November [ ], 2001, among the Trustees of
the Issuer named therein, the Guarantor, as sponsor, and the holders from
time to time of undivided beneficial interests in the assets of the Issuer,
the Issuer is issuing on the date hereof up to $_________  aggregate
liquidated preference of its __% Common Securities (stated liquidation amount
$25 per common security) (the "Common Securities") representing undivided
beneficial interests in the assets of the Issuer and having the terms set
forth in the Declaration;

            WHEREAS, as incentive for the Holders to purchase the Common
Securities, the Guarantor desires to irrevocably and unconditionally agree, to
the extent set forth in this Common Securities Guarantee, to pay to the Holders
of the Common Securities the Guarantee Payments (as defined herein) and to make
certain other payments on the terms and conditions set forth herein; and

            WHEREAS, the Guarantor is also executing and delivering a guarantee
agreement (the "Preferred Securities Guarantee") in substantially identical
terms to this Common Securities Guarantee for the benefit of the holders of the
Preferred Securities (as defined herein), except that if an Event of Default (as
defined in the Indenture), has occurred and is continuing, the rights of Holders
of the Common Securities to receive Guarantee Payments under this Common
Securities Guarantee are subordinated to the rights of holders of Preferred
Securities to receive Guarantee Payments under the Preferred Securities
Guarantee.

            NOW, THEREFORE, in consideration of the purchase by each Holder of
Common Securities, which purchase the Guarantor hereby acknowledges and agrees
shall benefit the Guarantor, the Guarantor executes and delivers this Common
Securities Guarantee for the benefit of the Holders.

stock. If an Event of Default has occurred and is continuing under the

                           MEDIUM TERM NOTES, SERIES A

                                   MASTER NOTE

         This Master Note is one of a duly authorized issue of notes (the
"Notes") of the Company issued under the Indenture, dated as of October 1, 2000
(the "Base Indenture"), as amended or supplemented prior to the date hereof
(collectively, the "Indenture"), between the Company and The Chase Manhattan
Bank, as trustee (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 and
limitations of rights thereunder of the Company, the Trustee and the Holders of
the Notes (the "Holders"), and the terms upon which the Securities are, and are
to be, authenticated and delivered. Capitalized terms used and not otherwise
defined in this Master Note have the meanings ascribed to them in the Indenture.

         The Calculation Agent shall calculate the interest payable hereon in
accordance with the Indenture and will confirm in writing such calculation to
the Trustee and the Paying Agent (if other than the Trustee) immediately after
each determination. All determinations made by the Trustee shall be, in the
absence of manifest error, conclusive for all purposes and binding on the
Company and Holders.

         If an Event of Default with respect to the Notes shall occur and be
continuing, the Trustee, by notice to the Company, or the Holders of at least
25% in principal amount of all of the outstanding Notes, by notice to the
Company and the Trustee, may declare the principal of all the Notes 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 at any time by the Company and the Trustee
with the consent of the Holders of a majority in aggregate principal amount of
the Notes at the time outstanding. The Indenture also contains provisions
permitting the Holders of specified percentages in aggregate principal amount of
the Notes at the time outstanding, on behalf of the Holders of all Notes, 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 Master Note shall be conclusive and
binding upon such Holder and upon future Holders of this Master Note and of any
Note issued upon the registration of transfer hereof or in exchange therefor or
in lieu hereof whether or not notation of such consent or waiver is made upon
this Master Note.

         Holders may not enforce their rights pursuant to the Indenture or the
Notes except as provided in the Indenture. No reference herein to the Indenture
and no provision of this Master Note or 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 Master Note at the time, place, and rate, and
in the coin or currency, herein prescribed.
