         STATE AUTO FINANCIAL ANNOUNCES FIRST QUARTER EARNINGS

o        NET INCOME UP 60% OVER 1Q 2002

o        SOLID IMPROVEMENT IN MERIDIAN SEGMENT

o        COMBINED RATIO OF 95.2


COLUMBUS, OHIO (APRIL 30, 2003) - State Auto Financial Corporation (NASDAQ:
STFC) today announced record GAAP net earnings of $21,064,000 for the first
quarter ended March 31, 2003. GAAP net earnings were $0.53, per diluted share,
versus $0.33 for the same period last year. Net operational earnings* for the
quarter were $0.47 per diluted share, compared to $0.31 for the same period
2002.

STFC's first quarter revenue was $253,353,000, up 10.2% from $229,959,000 a year
earlier. Quarterly written premium increased 6.4% over the first quarter 2002.
The Company's GAAP combined ratio for the first quarter was 95.2 versus 98.5 for
the first quarter 2002. The improvement in the combined ratio this quarter over
the first quarter of 2002 can be attributed mainly to the continued improvements
in the Meridian segment of the business. The Meridian segment produced a
combined ratio of 91.0 for this quarter versus 105.1 a year ago.

"We are enormously proud of our second straight quarter of record earnings. This
achievement is a direct result of the efforts of associates throughout the
Company who have focused on the reformation of the Meridian segment, while
continuing to fine tune the State Auto segment of the business," said STFC
Chairman and CEO Bob Moone.

"Nevertheless, underwriting work is never done. We believe the implementation of
double-digit homeowners rate increases, coupled with our focus on new and
renewal underwriting guidelines, will lead to sustainable profit in this line.
Our decision to remain extremely conservative writers of workers' compensation
has served us well, but continued attention to commercial casualty pricing is in
order.

"We are convinced that every constituency, particularly our shareholders and
agency partners, enjoy tremendous value from profitable operations. Therefore,
we will continue to be unrelenting in our drive to maintain both targeted growth
and sound underwriting results," concluded Moone.

At $12.36 per share, STFC shareholders' book value has increased by 17.4% since
March 31, 2002.
