        Notes to Condensed Consolidated Financial Statements (Unaudited)


(1)      Basis of Presentation

         Professionals Group, Inc. ("Professionals Group") is an insurance
         holding company incorporated under Michigan law on January 31, 1996.
         Professionals Group owns all of the issued and outstanding common stock
         of ProNational Insurance Company ("ProNational"), a Michigan-domiciled
         property and casualty insurance company which primarily provides
         professional liability insurance coverages and services to health care
         providers. ProNational owns 77% of MEEMIC Holdings, Inc. ("MEEMIC
         Holdings"), a publicly traded insurance holding company which provides
         personal auto, homeowners, boat and umbrella coverages primarily for
         educational employees and their families through MEEMIC Insurance
         Company ("MEEMIC"), a Michigan-domiciled property and casualty
         insurance company. Professionals Group and subsidiaries are
         collectively referred to as "the Company."

         The accompanying unaudited condensed consolidated financial statements
         of the Company have been prepared in conformity with generally accepted
         accounting principles and with the instructions for Form 10-Q and Rule
         10-01 of Regulation S-X as they apply to interim financial information.
         Accordingly, they do not include all of the information and footnotes
         required by generally accepted accounting principles for complete
         financial statements. All significant intercompany transactions have
         been eliminated in consolidation.

         In the opinion of management, all adjustments (consisting of normal
         recurring adjustments) considered necessary for a fair presentation of
         financial position and results of operations have been included. The
         operating results for the three month and six month periods ended June
         30, 2000 are not necessarily indicative of the results to be expected
         for the year ending December 31, 2000.

         Certain 1999 amounts have been reclassified to conform to the 2000
         presentation.

(2)      Net Income Per Share

         Net income per share is computed by dividing net income by the weighted
         average number of shares of common stock and common stock equivalents
         (stock options and stock awards) outstanding during each period after
         giving effect to stock dividends and treasury shares, calculated on a
         daily basis. The weighted average common shares used for determining
         basic income per common share were 8,928,559 and 9,192,803 for the
         three months ended June 30, 2000 and 1999, respectively, and 8,933,360
         and 9,198,566 for the six months ended June 30, 2000 and 1999,
         respectively. The effect of dilutive stock options added 72,171 shares
         and 118,481 shares for the three months ended June 30, 2000 and 1999,
         respectively, and 74,628 shares and 134,942 shares for the six months
         ended June 30, 2000 and 1999, respectively for the computation of
         diluted income per common share.

(3)      Segment Information

         The Company is organized and operates principally in the property and
         casualty insurance industry and has three reportable segments -
         professional liability lines property and casualty insurance, personal
         lines property and casualty insurance, and investment operations. The
         accounting policies of the segments are the same as those described in
         the basis of presentation footnote of the Company's consolidated
         financial statements included in its Annual Report on Form 10-K for the
         year ended December 31, 1999. Revenue is primarily from unaffiliated
         customers. Identifiable assets by segment are those assets, including
         investment securities, used in the Company's operations. Corporate and
         other identifiable assets are principally cash and marketable
         securities. Segment information, for which results are regularly
         reviewed by Company management in making decisions about resources to
         be allocated to the segments and assess their performance, is
         summarized as follows:

(4)      Acquisition

         On July 1, 1999, Michigan Educational Employees Mutual Insurance
         Company completed its conversion to a stock insurance company and
         changed its name to MEEMIC Insurance Company ("MEEMIC"). As a result of
         the conversion, MEEMIC became a wholly owned subsidiary of MEEMIC
         Holdings, Inc. ("MEEMIC Holdings"), a publicly traded Michigan business
         corporation. As part of MEEMIC's conversion, the Company acquired
         5,065,517 shares, or 77%, of the outstanding common stock of MEEMIC
         Holdings, at a cost of $50.6 million. Of these shares, 2,302,209 shares
         were acquired upon the conversion of a $21.5 million promissory note
         (plus accrued interest of $1.5 million) previously issued by MEEMIC to
         ProNational. The remaining 2,763,308 shares were purchased by
         ProNational for cash of $27.6 million. This acquisition was accounted
         for as a purchase business combination. The excess of net assets
         acquired over cost was $19.6 million, and is being amortized on the
         straight-line method over 10 years. Beginning July 1, 1999, the
         financial results of MEEMIC Holdings have been consolidated into the
         financial results of the Company. The following unaudited pro forma
         information presents a summary of the consolidated results of
         operations of the Company for the six months ended June 30, 1999, as if
         this acquisition had occurred on January 1, 1999 (in thousands, except
         per share data):

(5)      Proposed Business Combination

         On June 22, 2000, Professionals Group entered into a definitive
         agreement with Medical Assurance, Inc. (NYSE: MAI) to consolidate the
         two companies. The two parties will form a new holding company, Medical
         and Professionals Assurance, Inc., making it the nation's third largest
         writer of liability insurance for health care professionals and
         facilities. Professionals Group shareholders will receive their choice
         of $12.00 of cash and $14.00 worth of shares of stock in the new
         holding company, or $26.00 in cash, for each share of Professionals
         Group stock they own. The agreement is subject to required regulatory
         and shareholder approvals and is expected to be completed in early
         2001. The Company filed a Current Report on Form 8-K with the
         Securities and Exchange Commission on June 30, 2000 regarding the
         agreement and plan of consolidation.

Item 2. Management's Discussion and Analysis of Financial Condition and
        Results of Operations

      The following discussion and analysis should be read in conjunction with
the condensed consolidated financial statements and the notes thereto included
elsewhere in this report and the Company's Annual Report on Form 10-K for the
year ended December 31, 1999. The following discussion of the financial
condition and results of operations of the Company contains certain
forward-looking statements relating to anticipated future financial conditions
and operating results of the Company and its current business plans. In the
future, the financial condition and operating results of the Company could
differ materially from those discussed herein and its current business plans
could be altered in response to market conditions and other factors beyond the
Company's control. Important factors that could cause or contribute to such
differences or changes include those discussed in the Company's Annual Report on
Form 10-K for the year ended December 31, 1999. (See the disclosures under "Item
1. Business - Forward Looking Statements" and under "Item 7. Management's
Discussion and Analysis of Financial Condition and Results of Operations.")

Overview:

      Professionals Group is organized and operates principally in the property
and casualty insurance industry and has two insurance product segments. The
professional liability segment provides insurance coverage and services to
health care providers through Professionals Group's wholly owned subsidiary,
ProNational Insurance Company. The personal lines segment provides personal
auto, homeowners, boat and umbrella coverages primarily for educational
employees and their families through Professionals Group's majority owned
subsidiary, MEEMIC Holdings, Inc. and MEEMIC Holdings' wholly owned subsidiary,
MEEMIC Insurance Company.

      On July 1, 1999, MEEMIC Holdings was consolidated into Professionals
Group's financial statements as a result of Professionals Group obtaining
majority ownership (see also Note 4 to the Company's condensed consolidated
financial statements). The transaction was accounted for as a purchase business
combination. The three and six month 1999 results attributable to MEEMIC were
pursuant to the then existing management services agreement and quota share
reinsurance agreement, both of which were terminated on July 1, 1999.

Financial Condition -- June 30, 2000 Compared to December 31, 1999:

      Total assets increased $38.8 million, or 3.6%, to $1,110.9 million at June
30, 2000, compared to $1,072.1 million at December 31, 1999. Invested assets
increased 2.5% to $777.3 million, or approximately 70% of the Company's total
assets at June 30, 2000. This compares to invested assets of $758.3 million, or
approximately 71% of the Company's total assets at December 31, 1999. The
increase in invested assets was due primarily to positive cash flows generated
by operations. Reinsurance balances have increased due primarily to an increase
of medical malpractice business sold at higher limits, resulting in greater
reinsurance participation, therefore reinsurance recoverables have continued to
increase. Premiums due from policyholders and prepaid reinsurance premiums also
increased due primarily to the timing of renewals of ProNational's professional
liability business, a significant portion of which renews during the first
quarter.

      The Company's investment portfolio continues to be dominated by fixed
maturity securities at June 30, 2000, and primarily consists of U.S. government
and agency bonds, high-quality corporate bonds, mortgage-backed and asset-backed
securities, redeemable preferred stocks and tax-exempt U.S. municipal bonds. The
entire fixed maturity portfolio, which is classified as available-for-sale, and
is carried at fair value, is sensitive


                                      -10-


<PAGE>   11


to interest rate changes. At June 30, 2000, the fixed maturity portfolio had net
unrealized losses of $17.8 million. At December 31, 1999, the fixed maturity
portfolio had net unrealized losses of $19.5 million. This change was due
primarily to fluctuating bond market values caused by changes in interest rates
in the marketplace.

      Loss and loss adjustment expense reserves represented approximately 75%
and 74% of the Company's consolidated liabilities at June 30, 2000 and December
31, 1999, respectively. These reserves are determined on the basis of individual
claims and actuarially determined estimates of future losses based on the
Company's past loss experience and projections as to future claims frequency,
severity, inflationary trends and settlement patterns. Estimating reserves, and
especially professional liability reserves, is a complex process that is heavily
dependent on judgment and involves many uncertainties. As a result, reserve
estimates may vary significantly from the eventual outcome. It has been the
practice of the Company to establish its loss and loss adjustment expense
reserves within the range of acceptable values periodically estimated by the
Company's consulting actuary. The Company's carried reserves are recorded based
on such actuarial estimates. The assumptions used in establishing the Company's
reserves are regularly reviewed by management and revised as new data becomes
available. Any adjustments necessary are generally reflected in current
operations.

      Loss and loss adjustment expense reserves increased $31.8 million, or
5.0%, to $663.8 million at June 30, 2000, from $632.0 million at December 31,
1999. This increase was due primarily to a general increase in professional
liability reserves (i.e., new reserves recorded exceeded payments on older
reserves) as well as a reduction in the Company's recognition of favorable prior
year professional liability reserve development. The reduction in the
recognition of favorable prior year development was based on a review of the
Company's reserving needs and on medical malpractice trends. The remainder of
this increase was due primarily to general allowances for growth in the number
of insured vehicles and homeowners policies in force in the Company's personal
lines segment.

      The unearned premium reserve increased $6.0 million, or 6.8%, to $93.3
million at June 30, 2000, from $87.3 million at December 31, 1999. The increase
was due primarily to the timing of renewals of the Company's professional
liability book of business, a significant portion of which renews during the
first quarter.

      Shareholders' equity increased $6.7 million, or 3.1%, to $223.5 million at
June 30, 2000, compared to $216.8 million at December 31, 1999. The increase in
shareholders' equity was due primarily to an increase in accumulated other
comprehensive income, consisting of unrealized gains on the investment portfolio
of $0.7 million and net income of $7.6 million, which was offset by other
decreases in shareholders' equity of $1.6 million (primarily related to the
Company's stock repurchase program) during the six month period ended June 30,
2000. The Company expects to use retained earnings to increase its capital base
and finance future growth and, therefore, there can be no assurance as to any
future cash dividends by the Company.

Results of Operations - Three Months Ended June 30, 2000 Compared to Three
Months Ended June 30, 1999:

Professional Liability Insurance Operations Segment:

      Professional liability net premiums written were $17.2 million for the
three months ended June 30, 2000, a decrease of $2.3 million, or 12.0%, compared
to net premiums written of $19.5 million for the three months



                                      -11-

<PAGE>   12



ended June 30, 1999. The decrease in professional liability net premiums written
was mainly due to price increases instituted by the Company (and a resulting
decrease in the number of insureds) and as a result of the Company's more
selective underwriting practices. The Company is endeavoring to obtain
additional premium per unit of risk in what continues to be a very price
competitive professional liability environment. Professional liability net
premiums earned were $26.8 million for the three months ended June 30, 2000, a
decrease of $1.7 million, or 5.7%, compared to $28.5 million for the three
months ended June 30, 1999. The decrease in professional liability net premiums
earned was also due to the factors mentioned above.

      Professional liability insurance incurred losses and loss adjustment
expenses (including the increase in reserve for extended reporting period
claims) totaled $32.5 million for the three months ended June 30, 2000, an
increase of $6.2 million, or 23.3%, compared to $26.3 million for the three
months ended June 30, 1999. As a percentage of premiums earned, the professional
liability insurance incurred loss and loss adjustment expense ratio (including
the increase in reserve for extended reporting period claims) increased to
120.9% for the three months ended June 30, 2000, compared to 92.4% for the same
period of 1999. The professional liability insurance incurred loss and loss
adjustment expense ratio has increased due primarily to an increase in the
Florida-related professional liability loss ratio as well as a reduction in the
Company's recognition of favorable prior year reserve development (see previous
discussion). In addition, reinsurance benefits derived from a stop loss
reinsurance contract entered into for the 2000 accident year were $0.9 million
lower than the benefits received from the 1999 accident year stop loss
reinsurance contract.

      Professional liability policy acquisition and underwriting expenses were
$5.3 million for the three months ended June 30, 2000, a decrease of $3.1
million, or 36.4%, compared to policy acquisition and underwriting expenses of
$8.4 million for the same period of 1999. As a percentage of premiums earned,
the underwriting expense ratio decreased to 20.0% for the three months ended
June 30, 2000, from 29.6% for the same period of 1999. This decrease was due
primarily to $2.0 million in severance expenses incurred during the three months
ended June 30, 1999 in connection with the resignation of three executives.
Policy acquisition costs have also decreased in 2000 due to the reduction of
written premiums.

Personal Lines Insurance Operations Segment:

      Personal lines net premiums written were $31.5 million for the three
months ended June 30, 2000, an increase of $20.2 million, or 177.4%, compared to
net premiums written of $11.3 million for the three months ended June 30, 1999
(pursuant to the then existing quota share reinsurance relationship with
MEEMIC). Personal lines net premiums earned were $29.1 million for the three
months ended June 30, 2000, an increase of $17.8 million, or 156.2%, compared to
net premiums earned of $11.3 million for the three months ended June 30, 1999
(pursuant to the then existing quota share reinsurance relationship with
MEEMIC). The increase in both net premiums written and net premiums earned was
due to the July 1, 1999 acquisition of MEEMIC Holdings.

      Personal lines insurance incurred losses and loss adjustment expenses
totaled $18.2 million for the three months ended June 30, 2000, an increase of
$12.6 million, or 224.4%, compared to $5.6 million for the same period of 1999
(pursuant to the then existing quota share reinsurance relationship with
MEEMIC). The increase in incurred losses and loss adjustment expenses was due to
the July 1, 1999 acquisition of MEEMIC Holdings. As a percentage of premiums
earned, the personal lines insurance incurred loss and loss adjustment expense
ratio increased to 62.7% for the three months ended June 30, 2000, compared to
49.5% for the same period of 1999 (pursuant to the then existing quota share
reinsurance relationship with MEEMIC). The


                                      -12-


<PAGE>   13

personal lines insurance incurred loss and loss adjustment expense ratio
benefited from favorable weather conditions in both 2000 and 1999.

      Personal lines policy acquisition and underwriting expenses were $5.8
million for the three months ended June 30, 2000, an increase of $2.5 million,
or 75.3%, compared to policy acquisition and underwriting expenses of $3.3
million for the same period of 1999 (pursuant to the then existing quota share
reinsurance relationship with MEEMIC). The increase in policy acquisition and
underwriting expenses was due to the July 1, 1999 acquisition of MEEMIC
Holdings.

General Insurance Operations:

      Net investment income, excluding net realized investment gains, was $11.5
million for the three months ended June 30, 2000, an increase of $2.1 million,
or 22.8%, compared to net investment income of $9.4 million for the three months
ended June 30, 1999. The increase reflects the addition of MEEMIC's investment
portfolio as of July 1, 1999. The weighted average tax equivalent book yield of
the fixed maturity portfolio was 7.1% and 6.8% as of June 30, 2000 and 1999,
respectively. Net realized investment gains were $0.1 million and $0.9 million
during the three month periods ended June 30, 2000 and 1999, respectively.
Interest expense was $0.3 million during both three month periods ended June 30,
2000 and 1999. See "Liquidity and Capital Resources."

      The Company recorded $0.6 million of federal income tax expense for the
three months ended June 30, 2000, compared to $1.6 million in federal income tax
expense during the same period in 1999. The effective tax rate was 9.6% for the
three months ended June 30, 2000, compared to 24.3% for the three months ended
June 30, 1999. The decrease in the effective tax rate was due primarily to the
large amount of tax exempt income included in the Company's pretax income during
the three months ended June 30, 2000 compared to the three months ended June 30,
1999.

      Net income for the three months ended June 30, 2000 was $4.5 million, or
$0.50 per diluted share on revenues of $68.9 million. This compares to net
income of $5.1 million, or $0.55 per diluted share on revenues of $51.4 million,
for the three months ended June 30, 1999. The reduction in earnings was
primarily attributable to the deterioration in the professional liability loss
and loss adjustment expense ratio, as discussed previously, which was partially
offset by an increase in earnings from the personal lines segment. Net income
has also been reduced to reflect the 23% minority interest of MEEMIC Holdings
not owned by Professionals Group.

Results of Operations - Six Months Ended June 30, 2000 Compared to Six Months
Ended June 30, 1999:

Professional Liability Insurance Operations Segment:

      Professional liability net premiums written were $57.1 million for the six
months ended June 30, 2000, a decrease of $7.2 million, or 11.2%, compared to
net premiums written of $64.3 million for the six months ended June 30, 1999.
The decrease in professional liability net premiums written was mainly due to
price increases instituted by the Company (and a resulting decrease in the
number of insureds) and as a result of the Company's more selective underwriting
practices. The Company is endeavoring to obtain additional premium per unit of
risk in what continues to be a very price competitive professional liability
environment. Professional liability net premiums earned were $54.9 million for
the six months ended June 30, 2000, a


                                      -13-


<PAGE>   14

decrease of $1.1 million, or 2.0%, compared to $56.0 million for the six months
ended June 30, 1999. The decrease in professional liability net premiums earned
was also due to the factors mentioned above.

      Professional liability insurance incurred losses and loss adjustment
expenses (including the increase in reserve for extended reporting period
claims) totaled $65.6 million for the six months ended June 30, 2000, an
increase of $13.2 million, or 25.1%, compared to $52.4 million for the six
months ended June 30, 1999. As a percentage of premiums earned, the professional
liability insurance incurred loss and loss adjustment expense ratio (including
the increase in reserve for extended reporting period claims) increased to
119.5% for the six months ended June 30, 2000, compared to 93.6% for the same
period of 1999. The professional liability insurance incurred loss and loss
adjustment expense ratio has increased due primarily to an increase in the
Florida-related professional liability loss ratio as well as a reduction in the
Company's recognition of favorable prior year reserve development (see previous
discussion). In addition, reinsurance benefits derived from a stop loss
reinsurance contract entered into for the 2000 accident year were $1.6 million
lower than the benefits received from the 1999 accident year stop loss
reinsurance contract.

      Professional liability policy acquisition and underwriting expenses were
$10.3 million for the six months ended June 30, 2000, a decrease of $2.9
million, or 21.6%, compared to policy acquisition and underwriting expenses of
$13.2 million for the same period of 1999. As a percentage of premiums earned,
the underwriting expense ratio decreased to 18.8% for the six months ended June
30, 2000, from 23.5% for the same period of 1999. This decrease was due
primarily to $2.0 million in severance expenses incurred during the six months
ended June 30, 1999 in connection with the resignation of three executives.
Policy acquisition costs have also decreased in 2000 due to the reduction of
written premiums.

Personal Lines Insurance Operations Segment:

      Personal lines net premiums written were $59.4 million for the six months
ended June 30, 2000, an increase of $36.9 million, or 164.0%, compared to net
premiums written of $22.5 million for the six months ended June 30, 1999
(pursuant to the then existing quota share reinsurance relationship with
MEEMIC). Personal lines net premiums earned were $57.7 million for the six
months ended June 30, 2000, an increase of $35.2 million, or 156.3%, compared to
net premiums earned of $22.5 million for the six months ended June 30, 1999
(pursuant to the then existing quota share reinsurance relationship with
MEEMIC). The increase in both net premiums written and net premiums earned was
due to the July 1, 1999 acquisition of MEEMIC Holdings.

      Personal lines insurance incurred losses and loss adjustment expenses
totaled $38.3 million for the six months ended June 30, 2000, an increase of
$25.9 million, or 209.2%, compared to $12.4 million for the same period of 1999
(pursuant to the then existing quota share reinsurance relationship with
MEEMIC). The increase in incurred losses and loss adjustment expenses was due to
the July 1, 1999 acquisition of MEEMIC Holdings. As a percentage of premiums
earned, the personal lines insurance incurred loss and loss adjustment expense
ratio increased to 66.4% for the six months ended June 30, 2000, compared to
55.1% for the same period of 1999 (pursuant to the then existing quota share
reinsurance relationship with MEEMIC). The personal lines insurance incurred
loss and loss adjustment expense ratio benefited from favorable weather
conditions in both 2000 and 1999.

      Personal lines policy acquisition and underwriting expenses were $12.4
million for the six months ended June 30, 2000, an increase of $5.7 million, or
84.1%, compared to policy acquisition and underwriting


                                      -14-



<PAGE>   15

expenses of $6.7 million for the same period of 1999 (pursuant to the then
existing quota share reinsurance relationship with MEEMIC). The increase in
policy acquisition and underwriting expenses was due to the July 1, 1999
acquisition of MEEMIC Holdings.

General Insurance Operations:

      Net investment income, excluding net realized investment gains, was $22.8
million for the six months ended June 30, 2000, an increase of $4.2 million, or
22.3%, compared to net investment income of $18.6 million for the six months
ended June 30, 1999. The increase reflects the addition of MEEMIC's investment
portfolio as of July 1, 1999. The weighted average tax equivalent book yield of
the fixed maturity portfolio was 7.1% and 6.8% as of June 30, 2000 and 1999,
respectively. Net realized investment gains were $0.2 million and $2.7 million
during the six month periods ended June 30, 2000 and 1999, respectively.
Interest expense was $0.6 million during both six month periods ended June 30,
2000 and 1999. See "Liquidity and Capital Resources."

      The Company recorded $0.5 million of federal income tax expense for the
six months ended June 30, 2000, compared to $3.5 million in federal income tax
expense during the same period in 1999. The effective tax rate was 5.1% for the
six months ended June 30, 2000, compared to 23.0% for the six months ended June
30, 1999. The decrease in the effective tax rate was due primarily to the large
amount of tax exempt income included in the Company's pretax income during the
six months ended June 30, 2000 compared to the six months ended June 30, 1999.

      Net income for the six months ended June 30, 2000 was $7.6 million, or
$0.84 per diluted share on revenues of $138.0 million. This compares to net
income of $11.8 million, or $1.26 per diluted share on revenues of $102.0
million, for the six months ended June 30, 1999. The reduction in earnings was
primarily attributable to the deterioration in the professional liability loss
and loss adjustment expense ratio, as discussed previously, which was partially
offset by an increase in earnings from the personal lines segment. Net income
has also been reduced to reflect the 23% minority interest of MEEMIC Holdings
not owned by Professionals Group.

Liquidity and Capital Resources:

      Liquidity describes the ability to generate sufficient cash flows to meet
the cash requirements of continuing operations. Liquidity, in the context of
insurance operations, is typically determined by two distinct operations:
underwriting and investing. Net cash flows from underwriting operations are used
to build an investment portfolio, which in turn produces future cash from
investment income. The Company continuously monitors available cash and
short-term investment balances in relation to projected cash needs to maintain
adequate balances for current payments while maximizing cash available for
longer term investment opportunities.

      The payment of losses, loss adjustment expenses and operating expenses in
the ordinary course of business represents the Company's principal need for
liquid funds. Payments for losses and loss adjustment expenses are distributed
fairly evenly throughout the year. Payments for reinsurance are made within
thirty days subsequent to the end of each quarter, with adjustments made after
each reinsurance year. Historically, cash used to pay for these items has been
provided by operations. The Company did not borrow any funds in the six month
periods ended June 30, 2000 or 1999. As of June 30, 2000, no material
commitments for


                                      -15-

<PAGE>   16

capital expenditures existed, and management believes the Company's present
liquidity, together with its expected cash flow from operations, will be
sufficient to fund its commitments for capital expenditures.

      Professionals Group has an unsecured bank term loan, bearing interest at
an adjustable rate of LIBOR plus 62.5 basis points (7.15% at June 30, 2000), and
payable quarterly (the "Credit Agreement"). As of June 30, 2000, the outstanding
principal balance was $14.5 million. The remaining principal payments are due on
April 30, as follows: 2001 - $3.0 million; 2002 - $3.5 million; 2003 - $3.5
million; and 2004 - $4.5 million. The Company paid the $3.0 million principal
amount due on April 30, 2000.

      The Credit Agreement prohibits the payment of cash dividends on
Professionals Group's common stock (except for cash paid in lieu of fractional
shares related to stock dividends declared). The Credit Agreement also requires
the Company to, among other things, maintain total consolidated shareholders'
equity of at least $80.0 million plus 50% of the preceding fiscal year's
consolidated net income, maintain a ratio of debt to equity of not more than
0.5:1 and maintain a fixed charges coverage ratio and an interest coverage ratio
(as defined by the Credit Agreement) of not less than 1.5:1 and 2.5:1,
respectively. The Company was in compliance with, or had received waivers of,
all required covenants at June 30, 2000.

      On April 14, 1999, Professionals Group's Board of Directors authorized
management to repurchase up to 400,000 shares of the Company's common stock. On
December 11, 1999, the Board of Directors approved an increase in the number of
shares available to be repurchased to 440,000 shares. This increase was approved
to reflect the additional shares outstanding due to the 10% stock dividend
declared on November 15, 1999. The Board also extended the stock repurchase
program from April 28, 2000 to September 30, 2000. The Company repurchased
95,435 shares under this plan at a total cost of $2.2 million during the six
months ended June 30, 2000. As of June 30, 2000, 104,917 shares were available
to be repurchased under this program; and the Company did repurchase all of such
shares for $2.5 million and completed the stock repurchase program on July 13,
2000.

      On July 1, 1999, MEEMIC completed its conversion to a stock insurance
company. As a result of the conversion, MEEMIC became a wholly owned subsidiary
of MEEMIC Holdings, Inc., a publicly traded Michigan business corporation
(Nasdaq: MEMH). As part of MEEMIC's conversion, the Company acquired 5,065,517
shares, or 77%, of the outstanding common stock of MEEMIC Holdings, at a cost of
$50.6 million. Of these shares, 2,302,209 shares were acquired upon the
conversion of a $21.5 million promissory note (plus accrued interest of $1.5
million) previously issued by MEEMIC to ProNational. The remaining 2,763,308
shares were purchased by ProNational for cash of $27.6 million. The excess of
net assets acquired over cost was $19.6 million. This acquisition was accounted
for as a purchase business combination. Beginning July 1, 1999, the financial
results of MEEMIC Holdings have been consolidated into the financial results of
the Company (see also Note 4 to the Company's condensed consolidated financial
statements).

      On June 22, 2000, Professionals Group entered into a definitive agreement
with Medical Assurance, Inc. (NYSE: MAI) to consolidate the two companies. The
two parties will form a new holding company, Medical and Professionals
Assurance, Inc., making it the nation's third largest writer of liability
insurance for health care professionals and facilities. Professionals Group
shareholders will receive their choice of $12.00 of cash and $14.00 worth of
shares of stock in the new holding company, or $26.00 in cash, for each share of
Professionals Group stock they own. The agreement is subject to required
regulatory and shareholder approvals and is expected to be completed in early
2001. The Company filed a Current Report on Form 8-K with the Securities and
Exchange Commission on June 30, 2000 regarding the agreement and plan of


                                      -16-

<PAGE>   17

consolidation. It is currently anticipated that the cash payable to shareholders
of Professionals Group will be financed from cash on hand and/or privately
placed indebtedness.

Effects of New Accounting Pronouncements:

      The Financial Accounting Standards Board has issued Statement of Financial
Accounting Standards No. 133 ("SFAS No. 133"), "Accounting for Derivative
Instruments and Hedging Activities", which is effective for fiscal quarters of
all fiscal years beginning after June 15, 2000 (as amended by SFAS No. 137).
SFAS No. 133 requires that all derivative instruments be recorded on the balance
sheet at fair value. Changes in the fair value of derivatives are recorded each
period in current earnings or other comprehensive income, depending on whether a
derivative is designated as part of a hedge transaction, and if it is, the type
of hedge transaction. As the Company currently does not use derivative
instruments, we anticipate that the adoption of SFAS No. 133 will not affect the
results of operations or financial position of the Company.

Item 3.  Quantitative and Qualitative Disclosures About Market Risk

General:

      The Company invests in fixed maturity, equity and short-term securities.
The Company's investment strategy recognizes the need to maintain capital
adequate to support its insurance operations. The Company evaluates the
risk/reward trade-off of investment opportunities, measuring their effects on
yield, stability, diversity, overall quality and liquidity of the investment
portfolio.

      As of June 30, 2000, the majority of the Company's investment portfolio
was invested in fixed maturity securities and short-term investments. The fixed
maturity securities primarily consisted of U.S. government and agency bonds,
high-quality corporate bonds, mortgage-backed and asset-backed securities,
redeemable preferred stocks and tax-exempt U.S. municipal bonds.

Qualitative Information About Market Risk:

      Investments in the Company's portfolio have varying degrees of risk. The
primary market risk exposure to the fixed maturity portfolio is interest rate
risk, which is managed somewhat by limiting the duration of ProNational's
portfolio to a defined range of 3.5 to 5.5 years and limiting the duration of
MEEMIC's portfolio to a maximum of 300% of the duration of MEEMIC's liabilities.
The distribution of maturities and sector concentrations is monitored on a
regular basis. Equity securities (common stocks), which generally have greater
risk and volatility of market value, are not significant to the Company's
overall investment portfolio; therefore, exposure to equity price risk is not
significant. However, market values of equity securities are monitored
regularly.

      The Company regularly examines the quality distribution of its investment
portfolio for evidence of impairment. In such cases, changes in market value are
evaluated to determine the extent to which such changes are attributable to: (i)
interest rates, (ii) market-related factors other than interest rates and (iii)
financial conditions, business prospects and other fundamental factors specific
to the issuer. Declines attributable to issuer fundamentals are reviewed in
further detail. Available evidence is considered to estimate the realizable
value of the investment. When a security in the Company's investment portfolio
has a decline in market value which is other than temporary, the Company is
required by GAAP to reduce the carrying


                                      -17-

<PAGE>   18

value of such security to its net realizable value. All declines in market
values of the Company's investment securities at June 30, 2000 were deemed to be
temporary.

      The Company currently has no market risk exposure to foreign currency
exchange rate risk or commodity price risk.

Quantitative Information About Market Risk:

      Financial instruments subject to interest rate risk as of June 30, 2000
and December 31, 1999 were as follows:

      The Company does not invest in fixed maturity securities for trading
purposes. Exposure to risk is represented in terms of changes in fair value due
to selected hypothetical movements in market interest rates. Bonds and preferred
stocks are individually priced to yield to the worst case scenario. Securities
issued by states of the United States and political subdivisions of the states
are assumed to hold their prepayment patterns. Mortgage-backed and asset-backed
securities are priced assuming deal specific prepayment scenarios, considering
the deal structure, prepayment penalties, yield maintenance agreements and the
underlying collateral. All of the preferred stocks have mechanisms that are
expected to provide an opportunity to liquidate at par.

and 10% decrease in the market prices as of June 30, 2000 and December 31, 1999.
The selected hypothetical change does not reflect what could be considered the
best or worst case scenarios.

      The Company generally does not invest in equity securities for trading
purposes. As of June 30, 2000 and December 31, 1999, equity securities
represented less than 1% of the Company's total assets. The carrying values of
publicly traded investments subject to equity price risk are based on quoted
market prices as of the balance sheet date. Market prices are subject to
fluctuation and, consequently, the amount realized in the subsequent sale of the
investment may significantly differ from the reported market value. Fluctuation
in the market price of a security may result from perceived changes in the
underlying economic characteristics of the investee, the relative prices of
alternative investments and general market conditions. Furthermore, amounts
realized in the sale of a particular security may be affected by the relative
quantity of the security being sold. The carrying values of privately held
investments are subject to equity price risk which are based on the forgoing
market price considerations and also on the underlying value of the issuer and
other buyer's perceptions of such value, as well as lack of liquidity
considerations.
