             STATE AUTO FINANCIAL ANNOUNCES SECOND QUARTER EARNINGS

            - PROFIT ACHIEVED DESPITE HEAVY STORM ACTIVITY

            - CORE BUSINESS PERFORMED EXCEPTIONALLY WELL


COLUMBUS, OHIO (JULY 31, 2003) - State Auto Financial Corporation (NASDAQ: STFC)
today reported second quarter net income of $8,301,000, or $0.21 per diluted
share, versus a loss of $1,385,000 or $0.04 per diluted share for the same
period 2002. Net operating earnings* per share were $0.14 diluted, versus a loss
of $0.02 diluted, for the same period 2002.

STFC's GAAP combined ratio for the second quarter was 103.8 versus 108.6 for the
second quarter 2002. Catastrophe losses added a total of 17.1 points to the loss
ratio during the quarter. STFC's second quarter revenue was $263,160,000, up
11.4% from $236,223,000. Second quarter written premium increased 5.5% over the
second quarter 2002.

Revenue for the first six months 2003 was $516,512,000, up 10.8% from
$466,182,000. For the first six months of 2003, net income was $29,365,000, or
$0.74 per diluted share, compared with $11,779,000 or $0.29 per diluted share
for the same 2002 period. Year to date GAAP combined ratio for 2003 stands at
99.6 compared to 103.7 for 2002. STFC shareholders' book value per share has
increased by 10.0% during the first six months of 2003 to $13.08 per share.

"Given the momentum of two straight record-breaking quarters, the negative
impact of CAT 88 on the second quarter of 2003 was a disappointment. This storm,
which was previously reported, caused damage in 17 states over a nine-day period
and has developed into the costliest single catastrophe event in State Auto's
history. We are never satisfied unless we achieve an underwriting profit in each
period. Still, it is instructive to recognize that continued improvement in each
reporting segment of our core book of business allowed us to come within four
points of that goal despite these record CAT losses. It is also gratifying that
we were able to post a positive net income

and increase shareholder book value during the quarter," said STFC Chairman and
CEO Bob Moone.
