                 ProAssurance Reports First Quarter 2006 Results

    BIRMINGHAM, Ala.--(BUSINESS WIRE)--May 9, 2006--ProAssurance
Corporation (NYSE: PRA):

    SUMMARY

    ProAssurance reports an 11.5% year-over-year increase in Gross
Premiums Written in the first quarter of 2006, driven by growth from
the Company's addition of NCRIC, Inc. ProAssurance also reports a
$4.01 increase in Book Value per Share in the first quarter, primarily
as a result of the sale of MEEMIC Insurance Company, its personal
lines business.
    Income from Continuing Operations was $27.8 million, or $0.84 per
diluted share, and the MEEMIC sale resulted in $109.4 million of
Income from Discontinued Operations. Together this produced Net Income
of $137.3 million, or $4.05 per diluted share for the quarter. Cash
flow from Continuing Operations was $115.8 million, 24% higher than
the first quarter of 2005.

    ProAssurance Corporation (NYSE: PRA) reported first quarter 2006
results today. The Company's Continuing Operations reflect results
from its Professional Liability insurance business. Discontinued
Operations reflect results from the Company's former Personal Lines
business, which was sold effective January 1, 2006.

    Commentary on Results from Continuing Operations

    --  Premiums and policyholder count continue to grow as a result
        of the acquisition of NCRIC. Gross Written Premiums were 11.5%
        higher due to the inclusion of premiums from renewing NCRIC
        policyholders.

    --  With our rates at what we believe to be adequate levels, our
        need for additional rate increases has lessened. In the
        quarter, premiums on renewing policies were 5% higher on
        average.

    --  Our policyholder retention edged upward to 87%, a one-point
        improvement over the same quarter in 2005.

    --  There was favorable net loss development of $4.0 million in
        the quarter, primarily due to reductions in our estimates of
        claim severity in accident years 2003 and 2004. There was no
        net loss development in the comparable quarter last year.

    --  ProAssurance adopted SFAS 123(R), "Share-Based Payments," in
        the first quarter of 2006, resulting in an expense of $1.9
        million, or $0.04 per diluted share. SFAS 123(R) expenses for
        the remainder of 2006 are estimated to be $900,000 per
        quarter.

    Proposed Transaction with PIC Wisconsin
