                                ----------------


         Option Agreement entered into as of the 11th day of March, 1997
("Option Agreement") by and between STATE AUTOMOBILE MUTUAL INSURANCE COMPANY,
an Ohio corporation ("Mutual"), and STATE AUTO FINANCIAL CORPORATION, an Ohio
corporation ("Financial").

         WHEREAS, Mutual heretofore has entered into a Stock Purchase Agreement
dated as of December 12, 1996 ("Stock Purchase Agreement") pursuant to which
Mutual has agreed to purchase from R. W. Houser, Inc. a Wisconsin corporation,
for cash (the "Mutual Acquisition"), all of the issued and outstanding capital
stock of Midwest Security Insurance Company, a Wisconsin corporation
("Midwest"); and

         WHEREAS, Pursuant to the terms and provisions of the Stock Purchase
Agreement, Mutual on this date has purchased, and is now the owner of, all of
the outstanding capital stock of Midwest ; and

         WHEREAS, Mutual believes its value in Midwest will be enhanced in the
future if Midwest is owned by Financial, Mutual's 66% owned subsidiary; and

         WHEREAS, due to capital market uncertainties and the required cash
acquisition price for Midwest , Mutual's liquid capital resources facilitated
the acquisition of Midwest ; and

         WHEREAS, Mutual's ultimate objective is to increase its capital
liquidity to provide for continued growth and to enhance its position with
respect to risk base capital requirements, and ownership by Financial of Midwest
would advance these objectives; and

         WHEREAS, Financial over a period of time, will have access to capital
markets for the purpose of expanding its business; and

         WHEREAS, Financial has an interest in obtaining an option to purchase
Midwest and Mutual is willing to grant Financial such an option, in each case
subject to the terms and provisions of this Option Agreement; and

         WHEREAS, This Option Agreement has been reviewed and evaluated by the
Coordinating Committee of the Boards of Directors of Mutual and Financial, and
recommended for approval by such Coordinating Committee, and has been reviewed
and approved by the respective Boards of Directors of Mutual and Financial.

         NOW, THEREFORE, in consideration of the mutual provisions herein set
forth and subject to the terms and conditions hereof, the parties hereto agree
as follows:

         SECTION 1 - GRANT OF OPTION. In consideration of the payment by
Financial to Mutual of $25,000 ("Option Price"), the receipt and sufficiency of
which by Mutual is hereby acknowledged, and during a period of five (5) years
from the date hereof ("Option Term"), Mutual hereby grants to Financial the
exclusive right and option ("Option") to acquire Midwest, such acquisition, at
the exclusive election of Financial, to be structured as (i) a stock
acquisition, in the form of either the 



   3

acquisition of all of the capital stock of Midwest in exchange for cash, or the
acquisition of all of the capital stock of Midwest in exchange for common
shares, without par value, of Financial ("Financial Common Shares"), or any
combination of cash, and Financial Common Shares or (ii) a statutory merger, in
the form of either the merger of Midwest with and into Financial or a company
affiliated with Financial in exchange for Financial Common Shares or cash or any
combination of Financial Common Shares or cash, or the merger of a company
affiliated with Financial with and into Midwest in exchange for Financial Common
Shares or cash, or any combination of Financial Common Shares or cash, or (iii)
such other form of acquisition and form of consideration as may be agreed upon
by the parties hereto.

         SECTION 2 - EXERCISE OF OPTION; DEFINITIVE ACQUISITION AGREEMENT. At
any time during the Option Term Financial may elect to exercise the Option by
delivering written notice of exercise to Mutual setting forth the form of the
acquisition and the form of consideration to be paid ("Election"), together with
a proposed form of acquisition agreement. Upon receipt by Mutual of the Election
and the proposed form of acquisition agreement the parties hereto, subject to
the terms and conditions of this Option Agreement, promptly shall finalize and
execute or cause to be executed and use their reasonable best efforts to secure
any legally required director, shareholder and policyholder approvals of a
definitive acquisition agreement containing usual and customary terms and
provisions ("Definitive Acquisition Agreement"), the parties hereto agreeing to
bargain in good faith with respect to such terms and provisions. In addition,
upon exercise of the Option, Mutual and Financial agree to use their reasonable
best efforts to obtain, as promptly as practicable, all regulatory and
governmental approvals necessary to complete the acquisition.

         SECTION 3 - VALUATION OF MIDWEST, OF FINANCIAL COMMON SHARES, AND
FINANCIAL PREFERRED SHARES AND PURCHASE PRICE OF MIDWEST. Upon the Election by
Financial to exercise the Option, the purchase price for Midwest, as set forth
in the Definitive Acquisition Agreement, shall, if the form of the acquisition
is as set forth in Section 1(i) or 1(ii) above, be calculated as follows: (i)
Midwest shall be valued at its GAAP Book Value, as of the month end next
preceding the closing date described in the Definitive Acquisition Agreement,
adjusted through the last business day prior to the closing date described in
the Definitive Acquisition Agreement, times a multiple which is equivalent to
the multiple of Midwest's GAAP Book Value as of December 31, 1996 paid by Mutual
in connection with the Mutual Acquisition provided, however, that if at the time
the Option is exercised, the most recent market value to book value of the
Composite Statistics for the Property and Casualty Industry as published by
Value Line publishing, which index is 127 in its most recent report (1995) (the
"Index") should fall below 102 (the range minimum) or rise above 152 (the range
maximum), then in such event, the multiple pursuant to which the option price is
calculated as described in the preceding sentence shall be adjusted by
increasing the multiple by the amount by which the Index exceeds the range
maximum or by decreasing the multiple by the amount by which the Index is less
than the range minimum, as the case may be; (ii) Financial Common Shares shall
be valued at their closing sale price as reported on the NASDAQ National Market
System on the last business day prior to the closing date described in the
Definitive Acquisition Agreement, and (iii) Financial Preferred Shares shall be
valued at 100% of their call price, as described below. As used herein, GAAP
Book Value of Midwest means the assets, less liabilities, of Midwest, prepared
in accordance with generally accepted accounting principles.

         Cash and Financial Common Shares or any combination thereof, with a
value, calculated as set forth above, equal to the value of Midwest, calculated
as set forth above, shall be delivered by 


   4

Financial to Mutual on the closing date described in the Definitive Acquisition
Agreement in exchange for all of the outstanding capital stock of Midwest (or in
exchange for causing the merger of Midwest with and into Financial or a company
affiliated with Financial or the merger of a company affiliated with Financial
with and into Midwest) and shall represent the purchase price for Midwest .

         Upon the Election of Financial to exercise the Option, the purchase
price for Midwest, as set forth in the Definitive Acquisition Agreement, shall,
if the form of the acquisition is as set forth in Section 1(iii) above, be
calculated in a manner to be agreed upon by the parties hereto.

         SECTION 4 - RESTRICTIONS ON DISPOSITION AND REGISTRATION RIGHTS. Any
Financial Common Shares (together called "Shares") issued by Financial to Mutual
in connection with the Definitive Acquisition Agreement may be issued in
reliance upon an exemption from registration under the Securities Act of 1933,
as amended ("1933 Act") provided by Section 4(2) of the 1933 Act or any other
exemption deemed appropriate by Financial. As such, the Shares so received by
Mutual will be restricted as to their disposition and may not be sold or
otherwise disposed of by Mutual in the absence of (i) their registration under
the 1933 Act or, in the alternative, (ii) the receipt by Financial of an opinion
of counsel, reasonably acceptable in form and in substance to Financial, stating
that such registration is not required.

         If at any time after Mutual has received Shares of Financial in
connection with the Definitive Acquisition Agreement Financial files a
registration statement with the Securities and Exchange Commission
("Commission") on Form S-1, S-2 or S-3 with respect to Financial Common Shares,
then at Mutual's written request and subject to Mutual's bearing its
proportionate share of the registration expenses and any underwriting discount,
Financial agrees to include up to 100% of the Shares of Mutual so acquired as
part of Financial's registration statement, subject to Mutual's compliance with
the appropriate provisions of the 1933 Act and the rules and regulations
promulgated thereunder and to Mutual's agreement to the reasonable requests of
any managing underwriter(s) in connection with such registration.

         In addition, Financial agrees, at the written request of Mutual
received by Financial during a period of twenty-four (24) months after Mutual's
receipt of Shares of Financial pursuant to the Definitive Acquisition Agreement,
to use its best efforts to prepare and file with the Commission a registration
statement on Form S-1, S-2 or S-3 (to the extent Financial qualifies for the use
of such Forms) to register such Shares under the 1933 Act and to use its best
efforts to cause such registration statement to be declared effective, provided,
however, that Mutual shall bear all costs and expenses of such registration
statement.
