    BIRMINGHAM, Ala. & WASHINGTON, D.C.--(BUSINESS WIRE)--Feb. 28,

(NASDAQ: NCRI):

    SUMMARY

    ProAssurance Corporation and NCRIC Group, Inc. announce that NCRIC
will be merged into ProAssurance in a proposed stock-for-stock
transaction that values NCRIC at $10.10 per share, based on the
closing price of ProAssurance common stock on Friday, February 25,
2005. The transaction will expand ProAssurance's mid-Atlantic
operations in key states that meet its growth and return goals.
ProAssurance expects the transaction to be accretive to both book
value and earnings per share in 2005.

    ProAssurance Corporation (NYSE: PRA) and NCRIC Group, Inc.
(NASDAQ: NCRI) announced today an agreement to merge NCRIC into
ProAssurance in a $69.6 million, all-stock transaction which values
NCRIC at $10.10 per share based on the closing price of ProAssurance
common stock on Friday, February 25, 2005.
    Under the terms of the agreement each holder of common stock of
NCRIC will have the right to receive 0.25 of a share of ProAssurance
common stock for each share of NCRIC common stock. This exchange ratio
is subject to adjustment in the event that the market price of the
ProAssurance stock prior to the closing either exceeds $44 or is less
than $36 such that the exchange ratio would then be adjusted such that
the value per NCRIC share would neither exceed $11 nor be less than
$9, respectively. The transaction is subject to required regulatory
approvals and a vote of NCRIC stockholders and is expected to close
early in the third quarter of 2005.
    "The foundation of ProAssurance and our successor organizations is
built on identifying and successfully integrating companies that
strengthen our ability to expand our existing business," said A.
Derrill Crowe, M.D., the Chairman and CEO of ProAssurance. He praised
NCRIC's dominant market position and successful operations in its home
market of Washington, D.C., and added that NCRIC's presence in
Delaware and Virginia will make it a valuable addition to the
ProAssurance family of insurance companies. He said, "NCRIC is the
largest writer in Delaware and one of the top four writers in
Virginia. ProAssurance had already targeted both states for growth, so
we have an understanding of the market and we think this transaction
will give us an important boost."
    ProAssurance President and COO, Victor T. Adamo, said the Company
had conducted extensive due diligence with NCRIC's cooperation, with a
particular focus on NCRIC's loss reserves, their physician-focused
operating model, and the prospective profitability of their book of
business. He said, "NCRIC is today announcing actions to strengthen
their loss reserves. We believe this brings them to a level of
adequacy comparable to that of ProAssurance. Because NCRIC's
operational and financial goals are similar to those of ProAssurance,
we believe they will fit into our operating model with minimal
disruption for either organization."
    Dr. Crowe added, "NCRIC has a solid reputation for customer
service and advocacy that's much like ours. We plan to build on that
foundation as we apply ProAssurance's operating philosophy to ensure
our long-term success in those markets."
    R. Ray Pate, Jr., President and CEO of NCRIC commented that "the
affiliation with ProAssurance will provide significant benefits to our
stockholders, policyholders and staff, including enhanced liquidity
and added financial strength to better withstand the volatility
inherent in our business."
    Nelson P. Trujillo, M.D., Chairman of NCRIC further stated that
"Our policyholders have always counted on NCRIC to stand behind them
and we believe this transaction will allow us to continue to fulfill
that promise. We think ProAssurance is a model for combining
policyholder advocacy, balance sheet strength and financial
performance to ensure long-term success."
    The proposed transaction would add $87.2 million in gross written
premiums to ProAssurance's Professional Liability segment and increase
ProAssurance's assets by $292.9 million, based on NCRIC's unaudited
2004 results. NCRIC's stockholders' equity is $72.0 and its tangible
stockholders' equity is $64.7 million. ProAssurance expects the
transaction to be accretive to book value per share in 2005. The
transaction should also be accretive to earnings per share and will be
accounted for under the rules of purchase accounting.
    ProAssurance's Board is being advised by Cochran, Caronia & Co.
and the Board of NCRIC is being advised by Sandler O'Neill & Partners,
L.P. The Boards of both companies have approved the transaction, which
is subject to ratification only by NCRIC stockholders. NCRIC's Board
has recommended that their stockholders approve the consolidation. The
transaction is also subject to regulatory approvals.
    The proposed transaction will be submitted to NCRIC's stockholders
for their consideration. ProAssurance and NCRIC will file with the SEC
a registration statement and a proxy statement/prospectus and other
relevant documents concerning the proposed transaction. Stockholders
