    Operating Income is a "Non-GAAP" financial measure which
ProAssurance defines as Net Income, excluding the after-tax effects of
guaranty fund assessments, capital gains/losses and the results of
accounting changes. This definition may differ from those used by
other companies. ProAssurance's management uses Operating Income
because guaranty fund assessments and accounting changes are out of
the Company's control, and the realization of investment gains or
losses is largely discretionary as to timing and therefore could
distort the comparability of results. ProAssurance uses Operating
Income as one of the measures to evaluate performance across reporting
periods and believes it is a useful tool for investors. The following
table reconciles Net Income to Operating Income:

    Chairman A. Derrill Crowe, M.D. said, "Our results in the third
quarter, and for the year-to-date, are indicative of the progress we
are making toward our fourth quarter consolidated combined ratio goal
of 102% to 103%. We expect that progress to continue as we move into
2004 and beyond as the clear leader in financial strength, customer
service and investor confidence."

    In the third quarter, there was $3.6 million positive reserve
development in personal lines; there was no prior period reserve
development in professional liability. For the nine months, there has
been $7.1 million of favorable development in personal lines, offset
by a $750,000 addition to professional liability in the second
quarter.
    Net unrealized gains (after-tax) in the investment portfolio were
$41.7 million at September 30, 2003, and $35.5 million at December 31,
2002. These net unrealized gains are primarily in fixed income
securities. Interest Expense in the quarter was $1.2 million, and was
$2.3 million for the first three quarters of 2003.
    Total Goodwill is $26.4 million; approximately $18.2 million of
that total is related to the consolidation with Professionals Group,
and $7.6 million is attributable to the Company's acquisition of the
outstanding minority shares of its MEEMIC Holdings subsidiary in the
first quarter of 2003. The Company did not repurchase any shares of
its common stock during the quarter; 1.02 million shares remain
authorized for repurchase.

    The companies in ProAssurance's professional liability segment are

Virginia, Inc., ProNational Insurance Company, and Red Mountain

    "We continue to be pleased with the progress we are making in
returning the professional liability segment to more acceptable levels
of profitability, but we remain aware of the turbulent nature of the
medical professional liability market, especially in the area of
losses and reserving. Along with our determination to maintain
financial discipline through adequate pricing and reserving, our
thorough underwriting and effective claims management is proving to be
best for the long-term interests of our policyholders and shareholders
alike," said Dr. Crowe.
    ProAssurance's President, Victor T. Adamo, pointed out that
ProAssurance's financial strength and customer commitment remains a
key feature in the Company's success. He said, "ProAssurance, with its
demonstrated track-record of financial stability and industry
expertise, continues to benefit from the turmoil in the marketplace as
competitors come under financial stress after years of under-pricing.
And, as established companies such as St. Paul and Farmer's leave the
business, our demonstrated ability to serve the market in the
long-term becomes increasingly important to the healthcare community."

    Personal Lines Segment

    MEEMIC Insurance Company (MEEMIC), the sole company in
ProAssurance's personal lines segment, principally provides auto and
homeowners' coverages, primarily for educational employees and their
families.

    "MEEMIC's results in the quarter were affected by losses,
primarily due to fire, that resulted from the mid-summer blackout in
the Midwest. This is an example of the unpredictable nature of the
personal lines business on a quarter-to-quarter basis, but the overall
results at MEEMIC continue to be among the best in the industry. While
the combined ratio did tick up, investors should not lose sight of
MEEMIC's extraordinary profitability and its continued growth in
premium and policyholder count," said Dr. Crowe.

    Conference Call Information

    ProAssurance will discuss these results in a conference call at
9:00 AM ET on Thursday, November 13, 2003. Investors may participate
by calling (800) 547-8960 or (706) 645-9133. The call will be webcast
on the Investor Relations section of the ProAssurance website,
ProAssurance.com, and at StreetEvents.com. There will be a telephone
replay through November 20, 2003 at (800) 642-1687 or (706) 645-9291
(access code 3263788), and an internet replay at the same websites.

    Expected Exercise of Options

    ProAssurance employees and directors are currently under a
temporary stock trading blackout pending release of this earnings
report. After that blackout period expires, and after insurance
regulatory approvals are obtained, Dr. Crowe expects to exercise
approximately 300,000 options. Dr. Crowe has told the Company he
expects to hold the shares that he will realize in that exercise, but
investors are cautioned that Dr. Crowe may sell existing shares to
fund the tax liability generated by the exercise. The Company believes
other officers may exercise options in the coming weeks to increase
their ProAssurance share holdings.
