    Operating Income is a "Non-GAAP" financial measure. ProAssurance
defines Operating Income 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 net realized 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. focused on the increase in
Operating Income as evidence that ProAssurance's disciplined approach
to professional liability pricing and underwriting is bearing fruit.
"We're pleased with the progress we've made, but more remains to be
done. Our results are improving as loss-driven price increases earn
their way to the bottom line. While our vigilance in underwriting and
adequate pricing has played a large role in these results, our
forceful approach to claims defense has also been a key factor, both
in enhancing the bottom line and delivering value for our customers,"
said Dr. Crowe. He also highlighted continued strength in the personal
lines segment. "MEEMIC's excellent results continue to drive our
profitability while our professional liability segment rebounds," he
said.

    Total Goodwill is $27.2 million. The Company's first quarter
acquisition of the outstanding minority shares of its MEEMIC Holdings
subsidiary added Goodwill of approximately $7.6 million. Goodwill from
the 2001 consolidation with Professionals Group accounts for
approximately $18.2 million.
    There are approximately $34.4 million in net unrealized gains
(after tax) in ProAssurance's investment portfolio, primarily in fixed
income securities. ProAssurance did not purchase any of its common
stock during the quarter, which leaves 1.02 million shares authorized
for repurchase.

    Professional Liability Segment

    The companies in ProAssurance's professional liability segment are
The Medical Assurance Company, Inc., Medical Assurance of West
Virginia, Inc., ProNational Insurance Company and Red Mountain
Casualty Insurance Company, Inc. Each focuses on the delivery of
professional liability insurance to physicians and surgeons, dentists,
hospitals, and others involved in the delivery of health care.

    "We focus on bringing value to our customers while at the same
time ensuring that we maintain the financial strength for which we are
known. The recent failure of another large competitor, and the
downgrade of several others, underscores the need to maintain the
strength of our balance sheet," said Dr. Crowe. "We make a promise of
protection and service each time we issue a policy, and our
disciplined approach to business helps us make certain we can keep
those promises," he added.
    Victor T. Adamo, President of ProAssurance, said the Company
modestly capitalized on expansion opportunities in the quarter and
added policyholders in existing markets, primarily because of the
regulatory problems of a southeastern competitor. "These are uncertain
times in the medical liability business, and insureds see the wisdom
of seeking out financially stable, service-oriented companies such as
ProAssurance. Our financial goals go hand-in-hand with our focus on
service and claims defense. Each helps solidify ProAssurance as a
leader in service to policyholders and returns to investors," Adamo
said.

    Personal Lines Segment

    MEEMIC Insurance Company (MEEMIC), the sole company in
ProAssurance's personal lines segment, principally provides auto and

    MEEMIC improved both its top and bottom line performance in the
quarter. Gross Premiums Written increased because of policyholder
growth in the automobile and homeowners lines, as well as higher
premiums for homeowners policies. Homeowners rates increased 22% in
July 2002, and those increases are earning their way to the bottom
line.
    "MEEMIC's ability to underwrite in a preferred market, and its
ability to handle claims with great efficiency, allows the Company to
charge premiums that are very competitive, while producing remarkable
returns," said Adamo. He also cited the favorable weather conditions
in the first quarter as a contributing factor in MEEMIC's outstanding
quarter. "We expect to produce good results in normal weather
quarters, and when the weather is favorable, the results are
outstanding, he said.
