    --  Gross Premiums were higher in 2006 than in 2005 because of the
        additional business generated by our acquisition of NCRIC,
        Inc. in August 2005 and from our acquisition of Physicians
        Insurance Company of Wisconsin (PIC Wisconsin) in August 2006.
        Gross Premiums Written were down in the fourth quarter,
        compared to last year's quarter, because of competitive
        overall market conditions. PIC Wisconsin did not materially
        contribute to premiums due to the timing of their renewals,
        which are weighted to the start of the first and third
        quarters.

    --  Policyholder retention for 2006 was 84% and 83% in the fourth
        quarter.

    --  Premiums on renewing policies were higher by 3% in 2006 and 1%
        in the fourth quarter compared to the same periods a year ago.
        ProAssurance continues pricing its policies at levels that are
        designed to maintain its margins, despite lower overall
        pricing in the marketplace.

    --  Favorable net loss reserve development totaled $36.3 million
        in 2006, with $13.3 million coming in the fourth quarter. This
        development continues to come primarily from the accident
        years 2002, 2003 and 2004.

    --  Return on Equity was 13.5% in 2006. Strong cash flow,
        resulting in increased investment income, along with favorable
        loss reserve development, drove an increase in ROE for the
        year.

    --  Book Value per Share grew by $9.02. Organic Book Value growth
        added $4.70 per share; the sale of ProAssurance's Personal
        Lines business and the purchase of PIC Wisconsin added $3.29
        and $1.03 to Book Value per Share respectively.

    Florida Verdict Commentary

    We continue to pursue post-trial and appellate relief in the $217
million malpractice verdict against insureds of one of our
subsidiaries in Tampa. We continue to believe, based upon our current
analysis of appellate and coverage issues, potential recoveries from
our insurance and reinsurance programs, potential settlement
discussions, as well as our historical settlement practices, that our
reserves are adequate. We are monitoring the developments with this
verdict, as we do all verdicts, and will make adjustments to our
reserves as necessary.

    Caution Regarding Forward-Looking Statements

    Any statements in this News Release that are not historical facts
are specifically identified as forward-looking statements. These
statements are based upon our estimates and anticipation of future
events and are subject to certain risks and uncertainties that could
cause actual results to vary materially from the expected results
described in the forward-looking statements. Forward-looking
statements are identified by words such as, but not limited to,
"anticipate," "believe," "estimate," "expect," "hope," "hopeful,"
"intend," "may," "optimistic," "potential," "preliminary," "project,"
"should," "will," and other analogous expressions. There are numerous
important factors that could cause our actual results to differ
materially from those in the forward-looking statements. Thus,
sentences and phrases that we use to convey our view of future events
and trends are expressly designated as forward-looking statements as
are sections of this news release clearly identified as giving our
outlook on future business.

    Forward-looking statements relating to our business include among
other things: statements concerning liquidity and capital
requirements, return on equity, financial ratios, net income,
premiums, losses and loss reserves, premium rates and retention of
current business, competition and market conditions, the expansion of
product lines, the development or acquisition of business in new
geographical areas, the availability of acceptable reinsurance,
actions by regulators and rating agencies, court judgment, legislative
actions, payment or performance of obligations under indebtedness,
payment of dividends, and other matters.

    These forward-looking statements highlight significant risks,
assumptions and uncertainties, including, among other things, the
following important factors that could affect the actual outcome of
future events:

    --  general economic conditions, either nationally or in our
        market area, that are worse than anticipated;

    --  regulatory and legislative actions or decisions that adversely
        affect our business plans or operations;

    --  inflation and changes in the interest rate environment;

    --  performance of financial markets and/or changes in the
        securities markets that adversely affect the fair value of our
        investments or operations;

    --  changes in laws or government regulations affecting medical
        professional liability insurance;

    --  changes to our ratings assigned by rating agencies;

    --  the effects of health care changes, including managed care;

    --  uncertainties inherent in the estimate of loss and loss
        adjustment expense reserves and reinsurance, and changes in
        the availability, cost, quality, or collectibility of
        reinsurance;

    --  bad faith litigation which may arise from our involvement in
        the settlement of claims;

    --  post-trial motions which may produce rulings adverse to us
        and/or appeals we undertake that may be unsuccessful;

    --  significantly increased competition among insurance providers
        and related pricing weaknesses in some markets;

    --  our ability to achieve continued growth through expansion into
        other states or through acquisitions or business combinations;

    --  the expected benefits from acquisitions may not be achieved or
        may be delayed longer than expected due to, among other
        reasons, business disruption, loss of customers and employees,
        increased operating costs or inability to achieve cost
        savings, and assumption of greater than expected liabilities;

    --  changes in accounting policies and practices that may be
        adopted by our regulatory agencies and the Financial
        Accounting Standards Board; and

    --  changes in our organization, compensation and benefit plans.

    You should not place undue reliance on any such forward-looking
statements, which speak only as of the date made. The factors listed
above could affect our financial performance and could cause actual
results for future periods to differ materially from any opinions or
statements expressed with respect to future periods in any current
statements. Except as required by law or regulations, we do not
undertake and specifically decline any obligation to publicly release
the result of any revisions that may be made to any forward-looking
statements to reflect events or circumstances after the date of such
statements or to reflect the occurrence of anticipated or
unanticipated events.

    Our results may differ materially from those we expect and discuss
in any forward-looking statements. The principal risk factors that may
cause these differences are described in various documents we file
