BIRMINGHAM, AL -- (BUSINESS WIRE) -- June 25, 2001 -- Shareholders of Medical
Assurance, Inc. (NYSE:MAI) have overwhelmingly approved the Company's planned
consolidation with Professionals Group (NASDAQ:PICM), under a new holding
company, ProAssurance Corporation (NYSE:PRA). The transaction received support
from more than 99% of the shareholders casting their ballots at a special
meeting today. Professionals Group shareholders also voted overwhelmingly in
favor of the consolidation at a separate meeting.

The insurance operations of the new organization, centered around The Medical
Assurance Company, Inc., ProNational Insurance Company and MEEMIC Insurance
Company, will continue to serve their customers from existing office locations.
Medical Assurance's Chairman and President A. Derrill Crowe, M.D., who will
serve as Chairman and Chief Executive Officer of ProAssurance, said, "We've been
working towards this day for many months and we're excited to be able to put our
plans into action. Despite the challenges that exist in the medical malpractice
segment of the insurance market, I believe ProAssurance has significant
opportunities in the years ahead. We expect to emerge from this market cycle in
a leading position in our niche." MEEMIC will continue as the leading provider
of personal automobile insurance and related products to educators in the state
of Michigan.

Professionals Group President Victor T. Adamo, Esq. will be ProAssurance's
Vice-Chairman, President and Chief Operating Officer. He said the combined
management team has set very high expectations for the new company, "We will
retain the customer-focused heritage that has been the hallmark of both Medical
Assurance and Professionals Group. By remaining customer focused, we'll be in a
position to deliver the kind of responsive service they expect, and the results
our shareholders expect as well."


Today's approvals will allow the merger to close as scheduled on Wednesday, June
27th. The newly formed company, ProAssurance Corporation, will begin trading on
the New York Stock Exchange on Thursday, June 28th under the symbol PRA.

Under terms of the consolidation, Professionals Group shareholders are eligible
to elect either $27.47 per share in cash, or $13.47 in cash and shares of
ProAssurance stock. The number of shares of ProAssurance stock to be distributed
for each share of Professionals Group stock will be fixed after the close of
trading today, in accordance with procedures described in Medical Assurance's
Proxy Statement for today's shareholders' meeting. The exchange ratio will be
announced in a separate news release. Professionals Group shareholders have
until 5:00 pm EDT on Wednesday, June 27th, to deliver their elections to Mellon
Investor Services at the address specified in the Proxy Statement.
