TO THE SHAREHOLDERS OF PROFESSIONALS GROUP...

    DURING 2000 the Professionals Group companies celebrated very significant
milestones in their corporate lives. On a combined basis, the Professionals
Group companies have provided insurance services to their customers for over
one-half century. In this letter, we would like to highlight and celebrate the
growth of our insurance group.

MEEMIC

    Although it is the newest member of Professionals Group, MEEMIC is actually
the oldest of our insurance companies. MEEMIC was founded in 1950 by a group of
Detroit teachers who were interested in providing low cost, high quality
automobile insurance to their fellow teachers. Over these past 50 years, MEEMIC
has remained dedicated to the educator market in Michigan. MEEMIC now boasts
over 132,000 policies in force and has expanded its coverages beyond personal
auto protection to include homeowners, personal watercraft and umbrella
policies.

[VICTOR T. ADAMO AND WILLIAM H. WOODHAMS PHOTO]

    MEEMIC became affiliated with Professionals Group in 1997 and has clearly
benefited by this association. MEEMIC completed a successful demutualization in
1999 and has increased its capital base to over $145 million, thus providing it
with the resources to expand and grow. In 1999, MEEMIC entered the ranks of the
100 largest writers of personal auto coverage in the United States.

PRONATIONAL

    ProNational Insurance Company is actually the combination of five
predecessor insurance entities, all sharing a common heritage and mission of
service to the medical profession.

    In 1975, physicians throughout the country were drawn into the "malpractice
crisis." After a sudden escalation of malpractice lawsuits, the commercial
carriers that were the primary source of medical malpractice insurance abruptly
ceased offering malpractice coverage. Different solutions were fashioned at the
state level to solve the crisis and provide affordable malpractice insurance
protection for practicing physicians.

   In Michigan, a group of Detroit-area physicians formed the Physicians Crisis
Committee to advocate for tort reform. As a result of this effort, the Michigan
legislature enacted a state-sponsored fund known as the Brown-McNeely Fund as a
temporary source of malpractice insurance. The Brown-McNeely Fund was launched
in 1975 and existed for five years.

    In 1980 the state decided to return this insurance product to the private
sector. The Physicians Crisis Committee, with the assistance of a doctor-owned
insurance company from Ohio, was selected to convert the Fund into a
stock-insurance company owned by its insured physicians. This company,
Physicians Insurance Company of Michigan (also known as "PICOM"), began offering
policies under its own name in the


                                                                                  
            1950                          1975                          1980                               1995

summer of 1980. PICOM focused on customer service and providing its
policyholders with a strong claims defense. Over time, PICOM expanded its
professional liability coverages to include clinics, dentists, hospitals,
podiatrists, and a number of other health care providers and institutions, as
well as lawyers and law firms.

    PICOM diversified outside of Michigan in 1995, when it assumed the book of
business of Associated Physicians Insurance Company. Similarly, in 1996, PICOM
absorbed the insureds of Indiana-based American Medical Insurance Exchange. Both
of these medical malpractice insurers were founded in the mid-1980s through the
cooperative efforts of physicians and insurance professionals to serve doctors
in their home states.

    While PICOM was serving physicians in the Midwest, a similar story was
developing in Florida. The State of Florida reacted to the malpractice crisis of
1975 by allowing physicians to band together to form self-insured trusts. Using
the trust mechanism, a group of southeastern Florida doctors established
Physicians Protective Trust Fund. Known for its customer focus and tough claims
defense, Physicians Protective Trust Fund went on to become the largest
malpractice insurance provider in Florida.

    In July of 1998, PICOM and Physicians Protective Trust Fund came together to
form ProNational Insurance Company. ProNational is now the fourteenth largest
medical malpractice insurer in the United States. It actively writes malpractice
coverage in nine states for over 15,000 policyholders and has a solid economic
base with over $200 million in statutory surplus. And, while it has grown in
scope and size, ProNational has remained dedicated to the principles of customer
service, physician involvement, and the strong defense of claims that had been
the hallmark of its predecessor organizations.

 PROFESSIONALS GROUP

    Professionals Group came into existence in 1996 to serve as the upstream
holding company for the group. Its roots as a publicly owned company trace back
to PICOM, which started trading as an over-the-counter public company in the
early 1980s and joined the Nasdaq Stock Market in 1993.

    Professionals Group is now the 125th largest insurance group in the United
States with written premiums in excess of $265 million and assets of $1.1
billion. In addition to the insurance services that its member companies provide
to their policy-holders, Professionals Group has worked diligently to provide
economic value for its shareholders. Over the long term, which is the nature of
our insurance products, Professionals Group has provided an excellent return. An
investment of $100 in 1985 in Professionals Group (PICOM) was worth $8,278 at
the end of 2000. This is an annual growth rate of 32%, which was more than twice
the annual growth rate of the S&P 500 over this same period.

    It is with pride that we at Professionals Group celebrate these important
anniversaries in 2000. While we definitely look forward to our future as a part
of a larger and stronger insurance group, we take this opportunity to celebrate
our past. We thank those men and women who used their skills and talents to
found our companies. We also thank the boards, committees and staff members who
have devoted their energy and careers over the past fifty years to assist the
Professionals Group companies in successfully serving our policyholders and
shareholders.
