             PROFESSIONALS GROUP REPORTS FIRST QUARTER 2001 RESULTS


         OKEMOS, MICH., MAY 8, 2001 -- PROFESSIONALS GROUP, INC. (NASDAQ: PICM)
REPORTS NET INCOME FOR THE QUARTER ENDED MARCH 31, 2001 WAS $2.7 MILLION ($0.29
PER DILUTED SHARE), COMPARED TO 2000 FIRST QUARTER NET INCOME OF $3.1 MILLION
($0.33 PER DILUTED SHARE). OPERATING INCOME FOR THE FIRST QUARTER OF 2001 WAS
$2.4 MILLION ($0.26 PER DILUTED SHARE), COMPARED TO $3.1 MILLION ($0.33 PER
DILUTED SHARE) DURING THE FIRST QUARTER OF 2000.

         Victor T. Adamo, President and Chief Executive Officer stated,
"Professionals Group's pending merger with Medical Assurance, Inc. is expected
to close by the end of June. Accordingly, this will be Professionals Group's
final quarterly report to shareholders. We express our thanks for the continuing
support of Professionals Group's shareholders; and, we look forward to becoming
a founding member of the new ProAssurance Corporation."

2001 First Quarter Financial Results:

         The personal lines segment (MEEMIC) generated net premiums earned of
$31.2 million during the first quarter of 2001, compared to $28.6 million during
the first quarter of 2000, an increase of 9.0% due primarily to an increase in
the number of insured vehicles and homes. Operating income attributable to
MEEMIC for the first quarter of 2001 was $3.1 million ($0.34 per diluted share),
compared to $2.9 million ($0.31 per diluted share) during the first quarter of
2000. This increase was due primarily to Professionals Group's increased
ownership interest in MEEMIC of 84% at March 31, 2001 compared to 77% at March
31, 2000. MEEMIC's combined ratio increased


   2

modestly from 93.6% in 2000 to 96.2% in 2001 due to a more harsh winter in 2001
compared to 2000.

         The professional liability lines segment (primarily medical malpractice
coverage for health care providers and institutions through ProNational
Insurance Company) generated net premiums earned of $31.8 million during the
first quarter of 2001, compared to $28.0 million during the first quarter of
2000, an increase of 13.5%. This increase was due primarily to significant rate
increases implemented in all markets during 2000 and 2001. The operating loss
attributable to ProNational for the first quarter of 2001 was $0.7 million
($0.08 loss per diluted share), compared to operating income of $0.2 million
($0.02 per diluted share) during the first quarter of 2000. Operating income for
the first quarter of 2000 included the recognition of favorable prior year
reserve development and reduced loss costs attributable to a stop loss
reinsurance contract, neither of which existed during the first quarter of 2001.
ProNational has posted current accident year reserves at the same loss ratios as
recommended in 2000 by its consulting actuary despite significant rate increases
in all markets. The decrease in operating income was mitigated by an increase in
the federal income tax benefit reported in 2001 compared to 2000.

         Professionals Group's net investment income increased 5.0%, to $11.8
million during the first quarter of 2001 compared to $11.2 million for the first
quarter of 2000.

         Professionals Group's book value per common share (excluding unrealized
appreciation/depreciation on the investment portfolio) increased to $27.16 at
March 31, 2001 compared to $26.82 at December 31, 2000.

Consolidation Update:

         On June 22, 2000, Professionals Group entered into a definitive
agreement to consolidate with Medical Assurance, Inc. (NYSE: MAI) and form a new
holding company, ProAssurance Corporation, that would be the nation's third
largest writer of liability insurance for health care professionals and
facilities. The proposed consolidation will be considered and voted upon by
Professionals Group's shareholders at a Special Meeting of Shareholders to be
held at 10:00 a.m. local time on June 25, 2001 at the company headquarters. The
record date for the Meeting was the close of business on April 27, 2001. The
proposed consolidation is expected to be closed before June 30, 2001, pending
receipt of, among other things, shareholder and final regulatory approvals.
