    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, "We believe ProAssurance's
performance so far this year validates our focus on adequate pricing
and careful underwriting in both segments of our business. Dr. Crowe
further explained that ProAssurance's commitment to its insureds also
plays a large role in the Company's success. He said, "As we have
increased prices to realistic levels to account for more severe loss
trends, we have also raised our already high expectations for the
quality of service we provide to our policyholders. That has helped us
retain desirable insureds, while attracting new customers who value
the strength of our balance sheet and our ability to keep our
long-term promise to resolve their insurance claims."

    Net unrealized gains (after-tax) in the investment portfolio were
$52.1 million at June 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 $491,000, and was $1.1
million for the first two quarters of 2003.
    Total Goodwill is $26.4 million. Goodwill from the 2001
consolidation with Professionals Group accounts for approximately
$18.2 million of that total, 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.

    Debt Issuance

    In the two weeks following the close of the second quarter,
ProAssurance sold $107.6 million of 3.9% convertible senior debentures
due 2023. The majority of the proceeds have been used to pay off the
Company's $67.5 million existing term bank financing; the remainder is
being used for general corporate purposes such as expanding the
Company's capacity to write additional professional liability
business.

    Ratings

    During the second quarter, A. M. Best affirmed the financial
strength of ProAssurance's insurance subsidiaries at "A-" (Excellent)
with a "Stable" outlook. Standard & Poor's affirmed its "A-" (Strong)
rating on ProAssurance and maintained its "Negative" outlook,
primarily because of concerns about the medical liability market.
ProAssurance's President, Victor T. Adamo, commented, "At a time when
many competitors have been downgraded, we believe the affirmation of
our ratings is another factor that differentiates ProAssurance in the
marketplace."

    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.

    "The medical professional liability market remains challenging,
but we believe our approach remains sound. Loss trends continue to
drive our pricing higher, and we are committed to maintaining the rate
adequacy we have worked so hard to achieve. The recent failure of one
competitor and the downgrade of several others provides us with a
clear example of what can happen to companies that believe they are
doing their customers a favor by charging less than adequate
premiums," said Dr. Crowe.
    "At a time when many other companies are exiting markets and
imposing moratoriums on new business, ProAssurance is able to write
new policies and address the need for new capacity in underserved
markets. We are an attractive insurer because of the integrity of our
balance sheet, but much of our success in retaining insureds and
attracting new business is also the result of the hard work and
dedication of our sales staff and the agents who represent our
companies," said Adamo.

    "MEEMIC's policyholder count is increasing as the Company expands
into under-represented areas in Michigan, and increases its
penetration in the parochial and higher education markets," said Dr.
Crowe. He pointed out that homeowners rates rose by 22% in July of
2002 and are now being fully earned on a larger policyholder base.
"The leveraging effect of higher rates, a preferred class of business
and a growing book of business drives the superior performance of
MEEMIC," he said.
