Item 1.  BUSINESS.

General
-------

      Merchants Group, Inc. (the "Company") was incorporated in August 1986 as a
Delaware holding company which, through its wholly owned subsidiary Merchants
Insurance Company of New Hampshire, Inc. ("MNH"), offers property and casualty
insurance to preferred risk individuals and small to medium sized businesses in
the northeastern United States.

Administration
--------------

      The Company and MNH operate and manage their business in conjunction with
Merchants Mutual Insurance Company ("Mutual"), a New York domiciled mutual
property and casualty insurance company, under a management agreement (the
"Management Agreement"). Mutual owns 10.0% of the Company's issued and
outstanding common stock. The Company and MNH do not have any operating assets
and have no employees. Under the Management Agreement, Mutual provides the
Company and MNH with the facilities, management and personnel required to
operate their day-to-day business. All costs incurred by Mutual with respect to
underwriting expenses are shared pro rata between Mutual and MNH based upon
their annual direct premiums written, and unallocated loss adjustment expenses
are allocated on the basis of the number of claims outstanding each month that
are attributable to each company. All of Mutual's and MNH's investment expenses
are shared pro rata based upon the average book value of the invested assets of
each company. MNH also pays Mutual an annual management fee of $50,000. The
Management Agreement requires that the Company and MNH pay Mutual 110% of
Mutual's costs of providing them with non-insurance related services, and that
the Company pay Mutual an annual fee of one half of one percent (.5%) of the
average book value of the Company's invested assets exclusive of the Company's
shares of MNH. Since the inception of the Management Agreement, Mutual has not
provided the Company or MNH with any non-insurance related services.

      The Management Agreement has certain features that are intended to prevent
conflicts of interest or to deal with them on an equitable basis should they
occur. Generally, business opportunities which are presented to the common
officers or employees of the companies must be presented to each company's Board
of Directors and approved and determined to be fair to each company in the
transaction by a majority of the directors of each company who are not
affiliated with any other company in the transaction.

      Any amendment to or modification of the Management Agreement must be
approved by the New York Insurance Department (the "Department"). The Management
Agreement provides that it may be terminated by any party to the agreement upon
five years written notice. On July 23, 1998, the Company gave notice of its
intention to terminate the Management Agreement to Mutual. Mutual and MNH have
jointly developed and paid for all accounting, computer and insurance marketing
systems used in their businesses. Upon termination of the Management Agreement,
each company will have the right, at no cost, to obtain copies of all these
systems, together with the right to use these systems in perpetuity.

                                       3

Marketing
---------

      The Company markets its products through approximately 684 independent
agents, which also represent Mutual. The Company's primary marketing efforts are
directed to those independent agents that are dedicated to providing superior
service to their customers. The Company believes the opportunity for growth
exists through further penetration of agencies that are strategically aligned
with the Company's commitment to growth in its targeted markets.

      The Company believes that as a regional insurance company it has certain
advantages, including a closer relationship with its agents and a better
knowledge of its operating territories, that enable it to compete effectively
against larger regional and national carriers. The Company believes it
distinguishes itself from its competitors by providing its agents and
policyholders with superior service and ease of doing business, products that
target certain segments of the commercial and personal insurance markets, and an
agents' compensation program which, in addition to standard commission rates,
provides agents with a profit sharing plan.

      The Company services its agents from five Strategic Business Centers and
from its home office in Buffalo, New York. The Strategic Business Centers are
located in the Company's operating territories and focus primarily on policy
sales and underwriting. The manager of a Strategic Business Center appoints new
agents, agrees upon annual unit sales and premium objectives with the principal
of the agency, and ensures that the principal of the agency communicates these
objectives to the agency's sales staff. Strategic Business Center managers and
Territorial Managers, or "TM's," develop customized business plans for each
agent, which identify the opportunities to increase business and the actions
required to achieve the objectives agreed to by the agent and the Company.

      TM's meet with targeted agents' sales staff on a frequent basis to
underwrite the Company's renewal policies, as well as to solicit policies new to
the agent and/or to the Company. TM's are equipped with electronic technology to
provide prompt and efficient pricing and communication and can provide quotes
for all lines of business at the agents' offices. The Company believes personal
contact between TM's, who have underwriting authority, and an agent's sales
staff provides the Company with a competitive advantage compared to many other
property and casualty insurers, whose field representatives have limited or no
underwriting authority. By placing an underwriting decision maker in the agent's
office, and thereby simplifying the underwriting process, the Company believes
it can maintain and improve the retention rate on its renewal policies, as well
as attract new policies.

      Each Strategic Business Center has an Agents' Advisory Council that meets
at least twice a year. The Advisory Councils provide a forum for the Company and
its agents to discuss issues of mutual interest, and to assure that the agents'
business needs are being met. Additionally, the Chairpersons of the Advisory
Councils from each Strategic Business Center meet twice each year with senior
officers of MNH.

      In addition to standard commissions paid as a percentage of premiums
written, the Company's agents are eligible to participate in the Agents' Profit
Sharing Plan. This plan rewards agents based on premiums written and the loss
and allocated loss adjustment expense ("LAE") ratio on business placed by the
agent with the Company. Payments under the Agents' Profit Sharing Plan for 1999
totaled $2,375,000, or 2.4% of total direct premiums written. The Company
believes the terms of its

                                       4
<PAGE>   5
Agents' Profit Sharing Plan encourage its agents to increase the volume of
profitable business they place with the Company.

      Unlike many of its competitors, the Company pays the same commission rate
on policies billed directly to the insured by the Company and on policies billed
to the agent and, in turn, re-billed to the insured by the agent. By offering to
bill the insured directly for both personal and commercial policies, the Company
helps its agents minimize their administrative costs without a reduction in
commission income. Approximately 90% of the voluntary premiums written by the
Company in 1999 were billed directly to policyholders.

      In order to assist its independent agents to compete more effectively with
insurance companies that have direct sales forces, and to strengthen its
relationship with those agents, the Company provides advanced automation
services. In 1999, the Company introduced the Merchants MerLink(TM) system.
MerLink(TM) enables independent agents to submit policies to Merchants over the
Internet using their existing business computer and software, and to have these
submissions automatically update the Company's insurance policy processing
system. The benefits to agents are simplified client management, more time
available for sales activities, and fewer errors. Currently, the Company is
using MerLink(TM) for policy transactions with approximately 82 agents for
private passenger automobile and homeowners' policies. The Company plans to
offer MerLink(TM) capability for commercial lines insurance policies during the
first half of 2000. The Company believes that developing automation capabilities
to facilitate the sharing of information with its agents will improve its
competitive position compared to other property and casualty insurers that do
not have such capabilities.

Insurance Underwriting
----------------------

      The Company is licensed to issue insurance policies in 13 states,
primarily in the northeastern United States. In 1999, net premiums written
totaled $94,470,000, with 58% of the net premiums written derived from
commercial lines of insurance and 42% from personal lines of insurance.

      The following table sets forth the distribution of the Company's direct
premiums written by state for the years indicated:

      The Company is licensed to underwrite most major lines of property and
casualty insurance. It issues policies primarily to preferred risk individuals
and small to medium sized commercial risks. In general, the Company does not
insure risks that involve a high potential of loss or have a long-tail reporting
period. The types of risks insured in the Company's lines of business include:

         o        Personal automobile - full coverage of family-owned standard
                  performance automobiles, generally requiring drivers with good
                  driving records during the past three years.

         o        Homeowners' - properties generally with no losses in the last
                  three years that are less than 30 years old and valued between
                  $125,000 and $500,000.

         o        Commercial automobile - primarily light and medium use
                  vehicles operating in a limited radius, with complete
                  background information required of all drivers.

         o        Commercial multi-peril - properties with medium to high
                  construction quality and low to moderate fire exposure, and
                  occupancies with low to moderate exposure to hazardous
                  materials and processes.

         o        General liability - low hazard service, mercantile and light
                  processing businesses, generally with three years of business
                  experience and with no losses in the last three years.

         o        Workers' compensation - risks with low loss frequency and
                  severity, low to moderate exposure to hazardous materials and
                  processes, and favorable experience modification factors.
                  Generally, workers' compensation insurance is written in
                  conjunction with other commercial insurance.

      The Company's underwriting strategy is to offer its insurance at rates
which are designed to cover its costs, including the costs of any involuntary
business associated with a particular line of insurance or a particular
territory. This pricing strategy makes the Company's rates non-competitive with
respect to certain lines of insurance or certain geographic regions. For
example, the Company's published rates for personal automobile insurance in the
densely populated areas within its region of operations are significantly higher
than those of some of its competitors. The Company believes that its pricing
strategy allows the Company to write the types of insurance for which the price
charged reflects the cost of providing coverage.

      Agents of the Company are also agents of Mutual, which generally sells the
same lines of insurance as the Company to standard risk individuals and
businesses. Applicants that meet the Company's preferred risk criteria are
issued policies by the Company. Applicants that do not meet the Company's
underwriting criteria, but which meet the less restrictive criteria of Mutual,
are issued policies by Mutual, generally at higher premium rates. From 1993
through 1995, under a quota share reinsurance agreement with Mutual, MNH assumed
10% of the standard risks insured by Mutual, which would not generally meet
MNH's more stringent underwriting guidelines. The terms of that agreement allow
Mutual to reduce its cessions to MNH to 0% of Mutual's direct voluntary premiums
written for any calendar year prior to the beginning of that calendar year.
Mutual has not ceded any of its voluntary direct written premiums to MNH under
this agreement since 1995 and has informed the Company that it will not cede any
of its voluntary direct written premiums to MNH in 2000.

      The Company establishes premium rates for most of its policies based on
its loss experience, in some cases after considering prospective loss costs
suggested by the Insurance Services Office, Inc., an industry advisory group,
for the preferred individual and commercial classes of business that it insures.
The Company establishes rates independently for its personal automobile and
homeowners insurance policies and its specialty products, such as its
Contractors Coverall Plus and businessowners' policies.

      The following table shows, for each of the years in the three year period
ended December 31, 1999 (i) the amount of the Company's net premiums written
attributable to various personal lines and commercial lines and (ii)
underwriting results attributable to each such line as measured by the calendar
year loss ratio for such line. The loss ratio is the ratio of incurred losses to
net premiums earned for a given period.

      Calendar year loss ratios set forth in the table above include an estimate
of losses for that accident year, as well as increases or decreases in estimates
made in that year for prior accident year losses. Depending on the size of the
increase or decrease in prior accident year losses, calendar year loss ratios
may not be as indicative of the profitability of policies in force in a
particular year as accident year loss ratios, which do not take into account
increases or decreases in reserves for prior accident year losses.

Commercial Lines
----------------

      The Company's commercial business is primarily retail and mercantile in
nature and generally consists of small to medium sized, low hazard commercial
risks which as a group have relatively stable loss ratios. The Company's
underwriting criteria exclude lines of business and classes of risks that are
considered by the Company to be high hazard or volatile, or which involve latent
injury potential or other long-tail liability exposures. Although the commercial
underwriting objectives of the Company and Mutual are similar, the Company has
refined its selection criteria to include specific classes of businesses,
occupancies, and operations with lower hazard ratings, which present a
relatively lower exposure to loss and are charged a correspondingly lower
premium. The Company offers specialized products within the commercial
multi-peril line such as the Contractors Coverall Plus for artisan and trade
contractors, and BusinessElite for specified retail, service and office risks.

      Despite the lack of significant premium rate increases in recent years in
most of its commercial lines and the significant level of competition in the
lines of business that the Company targets, the Company believes it can insure
commercial business profitably by selecting those classes of risks that offer
better than average profit potential. The Company competes for commercial
business based upon the service it provides to agents and policyholders, the
compensation it pays to its agents, and in certain instances, the price of its
products. The Company establishes prices after considering its costs, the
exposures inherent in a particular class of risk, estimated investment income,
projected future trends in loss frequency and severity, and the degree of
competition within a specific territory. Accordingly, the relative prices of the
Company's commercial products may vary considerably in relation to competitors'
prices.


Personal Lines
--------------


      The Company offers personal automobile and homeowners' insurance to
preferred risk individuals, generally requiring experienced drivers with no
accidents or moving violations in the last three years for personal automobile
insurance, and medium to high value homes with systems that are less than thirty
years old in fire protected areas for homeowners' insurance. Personal automobile
premium rates attempt to cover costs associated with required participation in
involuntary personal automobile programs, in addition to the costs directly
associated with the policies written voluntarily.

      The Company and Mutual have developed automated underwriting procedures
for personal automobile, homeowners and certain commercial lines of business,
which perform an initial review of policy applications based upon established
underwriting guidelines. Applications that do not meet the guidelines for
automated acceptance are either referred to underwriters who review the

                                       8
<PAGE>   9
applications and assess exposure, or rejected if the risk characteristics are
such that neither the Company nor Mutual would accept the applicant.

      As a condition to writing voluntary business in most states in which it
operates, the Company must participate in state-mandated programs which provide
insurance for individuals and businesses unable to obtain insurance voluntarily,
primarily for personal automobile insurance. The legislation creating these
programs usually allocates a pro rata portion of the risks attributable to such
insureds to each company writing voluntary business in the state on the basis of
its voluntary premiums written or the number of automobiles which it insures
voluntarily.

      The Company's gross (direct and assumed) premiums written attributable to
involuntary policies were $12,719,000, $6,036,000 and $3,726,000 in 1997, 1998
and 1999, respectively, mostly in New York. The Company is unable to predict the
level of its annual involuntary business for 2000 or future years.

Claims
------

      Insurance claims on policies written by the Company are investigated and
settled by claims adjusters employed by Mutual pursuant to the Management
Agreement. The Company and Mutual maintain several claims offices within their
operating territories. In areas where there is insufficient claim volume to
justify the cost of internal claims staff, the Company and Mutual use
independent appraisers and adjusters to investigate claims. The Company's claims
policy emphasizes timely investigation of claims, settlement of valid claims for
equitable amounts, maintenance of adequate reserves for claims and control of
external claims adjustment expenses. In order to support its claims policy, the
Company has implemented a program designed to ensure that as soon as practical,
claims are assigned an accurate value based on available information. The
program includes the centralization of certain branch claims operations and an
emphasis on the training of claims adjusters and supervisors by senior claims
staff. This claims policy is designed to support the Company's marketing policy
and provide agents and policyholders with prompt service and support.

      Claims settlement authority levels are established for each adjuster,
supervisor and manager based on their expertise and experience. When the Company
receives notice of a claim, it is assigned to an adjuster based upon its type,
severity and line of business. The claims staff then reviews the claim, obtains
appropriate information and establishes a loss reserve. Claims that exceed
certain dollar amounts or that cannot be readily settled are assigned to more
senior claims staff.

Loss and LAE Reserves
---------------------

      The Company, like other insurance companies, establishes reserves for
losses and LAE. These reserves are estimates intended to cover the probable
ultimate cost of settling all losses incurred and unpaid, including those losses
not yet reported to the Company. An insurer's ultimate liability is likely to
differ from its interim estimates because during the life of a claim, which may
be many years, additional facts affecting an insurer's liability may become
known. The reserves of an insurer are frequently adjusted based on monitoring by
the insurer and periodic review by state insurance departments. The Company
retains an independent actuarial firm to satisfy state insurance departments'
requirements with respect to the certification of reserves for losses and LAE.

                                       9
<PAGE>   10
      Loss reserves are established for known claims based on the type and
circumstance of the loss and the results of similar losses. For claims not yet
reported to the Company, loss reserves are based on statistical information from
previous experience periods adjusted for inflation, trends in court decisions
and economic conditions. LAE reserves are intended to cover the ultimate cost of
investigating all losses that have occurred and defending lawsuits, if any,
arising from these losses. LAE reserves are evaluated periodically using
statistical techniques which compare current costs with historical data.
Inflation is implicitly reflected in the reserving process through analysis of
cost trends and review of historical reserve results. With the exception of
workers' compensation claims, loss reserves are not discounted for financial
statement purposes.

      The Company's reserving process is based on the assumption that past
experiences, adjusted for the effect of current developments and trends, are
relevant in predicting future events. In the absence of specific developments,
the process also assumes that the legal climate regarding the claims process and
underlying liabilities remains constant. Other assumptions employed by the
Company or its actuarial firm change from time to time as circumstances change.
In estimating loss and LAE reserves, the Company employs a number of actuarial
methods, depending on their applicability to each line of business, in order to
balance the advantages and disadvantages of each method. No single method is
used to estimate loss and LAE reserves. Although different actuarial methods may
give rise to different reserve estimates, which may be higher or lower than the
reserves actually established by the Company, the Company believes that those
differences are not material.

      The Company has recorded changes in reserves for prior accident year
losses in most years. In 1997, the Company increased its reserves for prior
years by $4,508,000 primarily due to higher than anticipated severity of claims
on workers' compensation policies. In 1998 and 1999, the Company decreased its
reserves for prior years by $2,145,000 and $3,749,000, respectively, primarily
due to favorable loss experience related to automobile liability policies in
1998 and workers compensation policies in 1999.

      The first line of the following table presents, as of the end of the year
at the top of each column, the estimated amount of unpaid losses and LAE for
claims arising in that year and in all prior years, including claims that had
occurred but were not yet reported to the Company. For each column, the rows of
the table present, for the same group of claims, the amount of unpaid losses and
LAE as re-estimated as of the end of each succeeding year. The estimate is
modified as more information becomes known about the number and severity of
claims for each year. The "cumulative redundancy (deficiency)" represents the
change in the estimated amount of unpaid losses and LAE from the end of the year
at the top of each column through the end of 1999.

      For each column in the table, the change from the liability for losses and
LAE shown on the first line to the liability as re-estimated as of the end of
the following year was included in operating results for the following year.
That change includes the change in the previous year's column from the liability
as re-estimated one year later to the liability as re-estimated two years later
which, in turn, includes the change in the second preceding column from the
liability as re-estimated two years later to the liability as re-estimated three
years later, and so forth.

      The rows of the lower portion of the table present, as of the end of each
succeeding year, the amount of paid losses and LAE for claims unpaid at the end
of the year at the top of each column.

Reinsurance
-----------

      The Company follows the customary industry practice of reinsuring a
portion of the exposure under its policies and as consideration pays to its
reinsurers a portion of the premium received on its policies. Insurance is ceded
principally to reduce an insurer's liability on individual risks and to protect
against catastrophic losses. Although reinsurance does not legally discharge an
insurer from its primary liability for the full amount of coverage provided by
its policies, it does make the assuming reinsurer liable to the insurer to the
extent of the reinsurance ceded.

      The Company is a party to reinsurance contracts under which certain types
of policies are automatically reinsured without the need for approval by the
reinsurer with respect to the individual risks that are covered ("treaty"
reinsurance). The Company also is a party to reinsurance contracts which are
handled on an individual policy or per risk basis and require the specific
agreement of the reinsurer as to each risk insured ("facultative" reinsurance).
Occasionally, the Company may secure facultative reinsurance to supplement its
coverage under treaty reinsurance.

      Effective January 1, 1998, the Company changed its primary reinsurer and
coverage. Prior to that time, the Company's excess of loss arrangements for
automobile liability, general liability and workers' compensation insurance
provided for recovery of losses over $500,000 up to a maximum of $5,000,000 per
occurrence. For claims occurring prior to 1993, the $500,000 threshold was
indexed for inflation for casualty lines other than workers' compensation and
New York State no-fault, and applied retroactively to all occurrences until they
are settled. There was no index provision for casualty claims occurring after
1992. This coverage was supplemented by additional treaty reinsurance covering
losses up to $5,000,000 in excess of the first $5,000,000.

      Prior to January 1, 1998, property reinsurance agreements provided for
recovery of property losses over $500,000 up to $2,000,000 per occurrence
without any index provision. Property catastrophe coverage placed with many
reinsurers worldwide provided for recovery of 95% of $40,000,000, subject to
aggregate retained losses of $5,000,000 for each natural disaster. The
reinsurance premium rate paid varied for each line of business.

      Effective January 1, 1998, the new property and casualty excess of loss
reinsurance agreements provide for recovery of casualty losses over $500,000 up
to $10,000,000 per occurrence and property losses over $500,000 up to
$10,000,000 per occurrence. This coverage is supplemented by a contingent
casualty layer of reinsurance for workers' compensation claims of $5,000,000 in
excess of the first $10,000,000 subject to a calendar year limit of $20,000,000.
Property catastrophe coverage provides for recovery of 95% of $50,000,000,
subject to aggregate retained losses of $5,000,000 per occurrence. The property
catastrophe reinsurance coverage is shared by the Company and Mutual on a pro
rata basis based upon the gross reported losses of the Company and Mutual for a
covered event.

      In 1987, the Company and its primary reinsurer agreed to limit the losses
which could be recovered by the Company under its excess of loss treaties for
the 1980 through 1986 accident years in exchange for a cap on retrospective
premiums due to the reinsurer. At December 31, 1999, recoverable losses exceeded
the cap and the excess losses have been retained by the Company.

      Effective January 1, 1993, Mutual and MNH entered into a quota share
reinsurance agreement under which MNH may assume up to 10% of Mutual's direct
voluntary written premiums and related

                                       13
<PAGE>   14
losses and allocated LAE in exchange for a reinsurance commission of 35%. The
agreement also provides for MNH to pay a contingent commission to Mutual equal
to any underwriting profit on the premiums assumed. Mutual pays the ceded
premiums, net of commissions and paid losses, to MNH on a monthly basis and MNH
invests these funds and earns investment income. To the extent commissions and
paid losses exceed premiums, MNH is required to pay the net monthly balance to
Mutual. The agreement may be terminated by either party effective as of any
January 1 with the prior approval of the New York Superintendent of Insurance
and upon six months' notice to the other party. In addition, the agreement may
be terminated by MNH at any time if any amount payable to MNH by Mutual becomes
more than 90 days overdue or if there is a change in control of Mutual approved
by the New York Superintendent of Insurance. Further, the agreement allows
Mutual to reduce its cessions to MNH from a maximum of 10% to a minimum of 0% of
Mutual's direct voluntary premiums written for any calendar year prior to the
beginning of that calendar year. Mutual has not ceded any portion of its direct
voluntary written premiums to MNH since 1995 and has informed the Company that
it will not cede any voluntary direct written premiums to MNH in 2000.

Investments
-----------

      The primary source of funds for investment by the Company is premiums
collected. Although premiums, net of commissions and other underwriting costs,
are taken into income ratably over the terms of the policies, they provide funds
for investment from the date they are received. Similarly, although
establishment of and changes in reserves for losses and LAE are included in
results of operations immediately, the amounts so set aside are available to be
invested until the Company pays those claims.

      The investments of the Company are regulated by New Hampshire insurance
law and are reviewed by the Board of Directors of the Company. Other than
certain short-term investments held to maintain liquidity, the Company primarily
invests in medium-term bonds, mortgage-backed and other asset-backed securities
including collateralized mortgage obligations, and tax-exempt securities. The
mortgage-backed securities held by the Company are typically purchased at
expected yields which are greater than comparable maturity Treasury securities
and are AAA or AA rated.

      The Company had $15,982,000 of tax-exempt bonds in its investment
portfolio at December 31, 1999. The Company believes these tax-exempt bonds are
of high quality (rated A or better) and, at the time of purchase, offered an
after-tax total return greater than comparable taxable securities.

      At December 31, 1999, the Company had $2,544,000 of short-term investments
with maturities less than 30 days, and $11,082,000 of non-investment grade
securities. These non-investment grade securities represented 5% of the
investment portfolio as compared to $6,706,000, or 3%, of the investment
portfolio at December 31, 1998.

Competition
-----------

      The property and casualty insurance business is highly competitive. The
Company is in direct competition with many national and regional multiple-line
insurers, many of which are substantially larger than the Company and have
considerably greater financial resources. Competition is further intensified by
the independent agency system because each of the independent agents who sells
the Company's policies also represents one or more other insurers. Also, the
Company's agents compete with direct writing insurers and this indirectly
affects the Company.

      Historically, the property and casualty industry has tended to be cyclical
in nature. During the "up" cycle, or "hard market," the industry is
characterized by price increases, strengthening of loss and LAE reserves,
surplus growth and improved underwriting results. Near the end of the "up"
cycle, an increase in capacity causes insurance companies to begin to compete
for market share on the basis of price. This price competition causes the
emergence of the "down" cycle, or "soft market," characterized by a reduction in
the premium growth rate and a general decline in profitability. Generally, the
down cycle is eventually accompanied by a decline in the adequacy of loss and
LAE reserves and a decrease in premium writing capacity. The property and
casualty insurance industry has experienced a cyclical downturn for the past
several years due primarily to intense premium rate competition and an excess
capacity to write premiums. Many of the circumstances which led to the current
cyclical downturn in the property and casualty insurance industry continue to
exist, and the Company cannot predict when or if market conditions for the
industry will improve.

      MNH is subject to regulation under applicable insurance statutes,
including insurance holding company statutes, of the various states in which it
writes insurance. Insurance regulation is intended to provide safeguards for
policyholders rather than to protect stockholders of insurance companies or
their holding companies. Insurance laws of the various states establish
regulatory agencies with broad administrative powers including, but not limited
to, the power to grant or revoke licenses to transact

                                       16
<PAGE>   17
insurance business and to regulate trade practices, investments, premium rates,
the deposit of securities, the form and content of financial statements and
insurance policies, accounting practices and the maintenance of specified
reserves and capital. The regulatory agencies of each state have statutory
authority to enforce their laws and regulations through various administrative
orders, civil and criminal enforcement proceedings, and the suspension or
revocation of certificates of authority. In extreme cases, including insolvency,
impending insolvency and other matters, a regulatory authority may take over the
management and operation of an insurer's business and assets.

      Under insolvency or guaranty laws in the states in which MNH operates,
insurers doing business in those states can be assessed up to prescribed limits
for policyholder losses caused by other insurance companies that become
insolvent. The extent of any requirement for MNH to make any further payment
under these laws is not determinable. Most laws do provide, however, that an
assessment may be excused or deferred if it would threaten a solvent insurer's
financial strength. In addition, MNH is required to participate in various
mandatory pools or underwriting associations in certain states in which it
operates.

      The property and casualty insurance industry has been the subject of new
regulations and legislative activity in various states attempting to address the
affordability and availability of different lines of insurance. The regulations
and legislation generally restrict the discretion an insurance company has in
operating its business. It is not possible to predict the effect, if any, that
new regulations and legislation would have on the Company and MNH.

      The Company depends on cash dividends from MNH to pay cash dividends to
its stockholders and to meet its expenses. MNH is subject to New Hampshire state
insurance laws which restrict its ability to pay dividends without the prior
approval of state regulatory authorities. These restrictions limit dividends to
those that, when added to all other dividends paid within the preceding twelve
months, would not exceed 10% of the insurer's policyholders' surplus as of the
preceding December 31st. The maximum amount of dividends that MNH could pay
during any twelve month period ending in 2000 without the prior approval of the
New Hampshire Insurance Commissioner is $5,328,000. MNH paid the maximum
allowable dividend to the Company in 1999. Dividends were paid in January 1999,
May 1999 and September 1999, of $2,100,000, $1,400,000 and $1,600,000,
respectively. MNH paid a dividend of $2,200,000 to the Company on February 14,
2000 and as such is restricted from paying another dividend to the Company until
May, 2000.

      In certain states in which it operates, MNH is required to maintain
deposits with the appropriate regulatory authority to secure its obligations
under certain insurance policies written in the jurisdiction. At December 31,
1999, investments of MNH having a par value of $1,900,000 were on deposit with
regulatory authorities.

      MNH and Mutual are required to file detailed annual reports with the
appropriate regulatory agency in each of the states in which they do business.
Their business and accounts are subject to examination by such agencies at any
time, and the laws of many states require periodic examination. The State of New
Hampshire Insurance Department most recently examined the accounts of MNH as of
December 31, 1997. MNH's annual report as of that date was accepted as
submitted, without adjustment.

      In 1993 the National Association of Insurance Commissioners ("NAIC")
adopted a risk-based capital measurement formula to be applied to all property
and casualty insurance companies. The

                                       17
<PAGE>   18
formula calculates a minimum required statutory net worth, based on the
underwriting, investment, credit, loss reserve and other business risks inherent
in an individual company's operations. Any insurance company that does not meet
threshold risk-based capital measurement standards could be forced to reduce the
scope of its operations and ultimately could become subject to statutory
receivership proceedings. MNH's capital substantially exceeds the statutory
minimum as determined by the risk-based capital measurement formula as of
December 31, 1999.

      The NAIC has established eleven financial ratios (the Insurance Regulatory
Information System, or "IRIS") to assist state insurance departments in their
oversight of the financial condition of insurance companies operating in their
respective states. The NAIC calculates these ratios based on information
submitted by insurers on an annual basis and shares the information with the
applicable state insurance departments. The ratios relate to leverage,
profitability, liquidity and loss reserve development. Each of the Company's
ratios for 1999 falls within the usual or acceptable range as published by the
NAIC.

Rates
-----

      Premium rate regulations vary greatly among states and lines of insurance,
and frequently require approval of the regulatory authority or limited review by
the authority prior to changes in rates. However, in New York and certain other
states, insurers writing private passenger automobile policies and in designated
commercial risk, professional liability and public entity insurance markets may
periodically revise rates within the limits of applicable flexibility bands
("flex-bands") on a file and use basis, but must obtain the Department's prior
approval in order to implement rate increases or decreases beyond these
flex-bands.

Insurance Holding Companies
---------------------------

      The Company is subject to statutes governing insurance holding company
systems. Typically, such statutes require the Company to file information
periodically concerning its capital structure, ownership, financial condition
and general business operations and material inter-company transactions not in
the ordinary course of business. Under the terms of applicable New Hampshire
statutes, any person or entity desiring to purchase shares which would result in
such person beneficially owning 10% or more of the Company's outstanding voting
securities would be required to obtain regulatory approval prior to the
purchase.

Involuntary Insurance
---------------------

      As a condition to writing voluntary insurance in most of the states in
which it operates, the Company must participate in programs that provide
insurance for persons or businesses unable to obtain insurance voluntarily.
Uncertainties as to the size of the involuntary market population make it
difficult to predict the amount of involuntary business in a given year.

Employees
---------

      The Company has no employees. At December 31, 1999, Mutual had 346
full-time equivalent employees. The Company believes that Mutual's relationship
with its employees is satisfactory.

                                       18

Item 2.  PROPERTIES.

      Although the Company has no facilities, it benefits from the facilities of
Mutual pursuant to the Management Agreement, under which the Company is charged
a proportionate share of the costs of such facilities.

      The Company's corporate headquarters are located in Buffalo, New York in a
building owned by Mutual that contains approximately 113,000 square feet of
office space. Mutual also has regional underwriting and/or claims office
facilities in Buffalo, Albany and Hauppauge, New York; Manchester, New
Hampshire; and Moorestown, New Jersey. All of the offices except the Buffalo
office are leased.

Item 3.  LEGAL PROCEEDINGS.

      MNH, like many other property and casualty insurance companies, is subject
to environmental damage claims asserted by or against its insureds. Management
of the Company is of the opinion that based on various court decisions
throughout the country such claims should not be recoverable under the terms of
MNH's insurance policies because of either specific or general coverage
exclusions contained in the policies. However, there is no assurance that the
courts will agree with MNH's position in every case, nor can there be assurance
that material claims will not be asserted under policies which a court will find
do not explicitly or implicitly exclude claims for environmental damages.
Management, however, is not aware of any pending claim or group of claims which
would result in a liability that would have a material adverse effect on the
financial condition of the Company or MNH.

      In addition to the foregoing matters, MNH is a defendant in a number of
other legal proceedings in the ordinary course of its business. Management of
the Company is of the opinion that the ultimate aggregate liability, if any,
resulting from such proceedings will not materially affect the financial
condition of the Company or MNH.

Item 4.  SUBMISSION OF MATTERS TO A VOTE OF SECURITY HOLDERS.

None.

</TABLE>

       The number of stockholders of record of the Company's Common Stock as of
February 29, 2000 was 104. Securities held by nominees are counted as one
stockholder of record.

       The Company has paid a quarterly cash dividend to its common stockholders
since the third quarter of 1993. Continued payment of this dividend and its
amount will depend upon the Company's operating results, financial condition,
capital requirements and other relevant factors, including legal restrictions
applicable to the payment of dividends by its insurance subsidiary, MNH.

       As a holding company, the Company depends on dividends from its
subsidiary, MNH, to pay cash dividends to its stockholders. MNH is subject to
New Hampshire state insurance laws which restrict its ability to pay dividends
without the prior approval of state regulatory authorities. These restrictions
limit dividends to those that, when added to all other dividends paid within the
preceding twelve months, would not exceed 10% of the insurer's policyholders'
surplus as of the preceding December 31. The maximum amount of dividends that
MNH could pay during any twelve month period ending in 2000 without prior
approval of the New Hampshire Insurance Commissioner is $5,328,000.

Item 7.  MANAGEMENT'S DISCUSSION AND ANALYSIS OF FINANCIAL CONDITION AND RESULTS
OF OPERATIONS

1999 Compared to 1998.
----------------------

       Total revenues for 1999 were $108,416,000, an increase of $1,448,000, or
1%, from $106,968,000 in 1998.

       Direct premiums written for 1999 were $100,227,000, an increase of
$1,271,000, or 1%, from $98,956,000 in 1998. Net written premiums for 1999 were
$94,470,000, an increase of $1,712,000, or 2%, from $92,758,000 in 1998.

       Voluntary personal lines direct premiums written for 1999 were
$38,493,000, a decrease of 3% from $39,518,000 in 1998. Private passenger
automobile direct premiums written, which comprised 76% and 78% of total
voluntary personal lines direct premiums written in 1999 and 1998, respectively,
decreased 5% in 1999 compared to 1998 primarily due to fewer new policies and
renewal policies retained resulting from price-based market competition.
Voluntary private passenger automobile policies in force at December 31, 1999,
decreased 7% compared to December 31, 1998. Homeowners direct premiums written
increased 6% in 1999 compared to 1998 due to a 9% increase in policies in force
resulting from an increase in new business units in 1999 as compared to 1998.

       Voluntary commercial lines direct premiums written for 1999 were
$59,621,000, an increase of 10% from $54,246,000 in 1998. This increase resulted
primarily from a $3,173,000, or 21%, increase in commercial auto direct premiums
written, a $573,000, or 8%, increase in workers' compensation direct premiums
written and a $1,406,000, or 22%, increase in contractors coverall direct
premiums written.

       The increase in commercial auto direct premiums written was primarily due
to a 25% increase in policies in force at December 31, 1999 compared to December
31, 1998, partially offset by a 3% decrease in average premium per commercial
auto policy at December 31, 1999 compared to December 31, 1998. The commercial
auto market continues to respond favorably to the Company's commercial auto
product enhancements and premium rate decreases enacted in early 1998. The
increase in workers' compensation direct premiums written was due to a 9%
increase in new business units in 1999 as compared to 1998. The increase in
contractors coverall direct premiums written was primarily due to a 14% increase
in average policies in force in 1999 compared to 1998 which in turn was due to
rate decreases in this line of business effective in the first quarter of 1999.

       Involuntary direct premiums written, primarily involuntary private
passenger automobile insurance, which comprised 2% and 5% of total direct
premiums written during 1999 and 1998, respectively, were $2,113,000 for 1999
compared to $5,192,000 in 1998. This 59% decrease resulted primarily from
decreased mandatory assignments from the New York Automobile Insurance Plan
("NYAIP"), which provides coverage for individuals who are unable to obtain auto
insurance in the voluntary market. During 1999 the NYAIP continued to adjust its
assignments as a result of having over assigned policies to the Company in 1997
and an overall decrease in the NYAIP's pool of business. Assignments from the
NYAIP vary depending upon a company's private passenger automobile market share
and the size of the NYAIP.

       Net premiums earned for 1999 were $94,775,000, an increase of $1,235,000,
or 1%, from $93,540,000 in 1998. Net premiums earned increased primarily due to
the 1% increase in direct premiums written.

       Net investment income was $13,147,000 in 1999, a decrease of 1% from
$13,277,000 in 1998, due to a decrease in average portfolio yield. Average
invested assets in 1999 were substantially unchanged from 1998.

       Other revenues were $434,000 for 1999, an increase of $281,000 or 184%
from $153,000 in 1998, primarily due to increased income from residual market
facilities.

       Net losses and LAE were $66,086,000 for 1999, an increase of 1% from
$65,234,000 in 1998. The increase in net losses and LAE was primarily
attributable to a non-recurring charge related to insurance related assessments,
which was offset by a non-recurring reduction in other underwriting expenses.
Absent this non-recurring charge, net losses and LAE were relatively unchanged
compared to 1998. The Company recorded decreases to its reserves for losses
related to prior accident years of $3,749,000 and $2,145,000 in 1999 and 1998,
respectively. These decreases in reserves for prior accident years reduced the
loss and LAE ratio in 1999 and 1998 by 3.9 and 2.3 percentage points,
respectively, and were primarily the result of favorable loss experience related
to auto liability policies in 1998 and workers' compensation policies in 1999.
The decrease in reserves for prior accident years was somewhat offset by an
increase in the loss and LAE ratio for losses and LAE occurring in the current
accident year.

       Involuntary automobile insurance business increased the Company's
calendar year loss and LAE ratio by approximately 1.1 and 3.5 percentage points
for the years ended December 31, 1999 and 1998, respectively. The combined ratio
on involuntary automobile business was greater than the combined ratio on
voluntary automobile business.

       The ratio of policy acquisition costs and other underwriting expenses to
net premiums earned decreased to 34.5% in 1999 from 35.8% in 1998, primarily due
to the aforementioned non-recurring reduction in insurance related assessments.
Expenses that vary directly with the Company's premium volume, primarily
commissions, premium taxes and state assessments, represented 20.6% and 21.7% of
net premiums earned in 1999 and 1998, respectively. Certain other underwriting
expenses, such as salaries, employee benefits and other operating expenses vary
indirectly with volume and comprise the remainder of the Company's underwriting
expenses.

       The amounts recorded by the Company for income taxes in 1999 and 1998
differed from those calculated using the statutory federal income tax rate
primarily due to tax exempt bond income.

1998 Compared to 1997.
----------------------

       Total revenues for 1998 were $106,968,000, a decrease of $2,182,000, or
2%, from $109,150,000 in 1997.

       Direct premiums written for 1998 were $98,956,000, a decrease of
$2,108,000, or 2%, from $101,064,000 in 1997. Net premiums written for 1998 were
$92,758,000, a decrease of $4,053,000, or 4%, from $96,811,000 in 1997.

<PAGE>   25
       Voluntary personal lines direct premiums written for 1998 were
$39,518,000, substantially unchanged from $39,415,000 in 1997. Private passenger
automobile direct premiums written, which comprised 78% and 79% of total
voluntary personal lines direct premiums written in 1998 and 1997, respectively,
decreased 1% in 1998 compared to 1997 primarily due to intensified price-based
market competition. Homeowners direct premiums written increased 5% in 1998
compared to 1997 due to a 5% increase in average premium per policy.

       Voluntary commercial lines direct premiums written for 1998 were
$54,246,000, an increase of 5% from $51,572,000 in 1997. This increase resulted
primarily from a $1,260,000, or 9%, increase in commercial auto direct premiums
written, a $1,014,000, or 17%, increase in workers' compensation direct premiums
written and a $530,000, or 6%, increase in commercial package policies direct
premiums written.

       The increase in commercial auto direct premiums written was primarily due
to an 8% increase in average premium per policy at December 31, 1998 compared to
December 31, 1997. The increase in workers' compensation direct premiums written
was due to a 36% increase in new business units in 1998 as compared to 1997. The
increase in commercial package policy direct premiums written was due to an 11%
increase in policies in force at December 31, 1998 compared to 1997, partially
offset by a 3% decrease in average premium size.

       Involuntary direct premiums written, primarily involuntary private
passenger automobile insurance, which comprised 5% and 10% of total direct
premiums written during 1998 and 1997, respectively, were $5,192,000 for 1998
compared to $10,077,000 in 1997. This 48% decrease resulted primarily from
decreased mandatory assignments from the NYAIP, which provides coverage for
individuals who are unable to obtain auto insurance in the voluntary market.
During 1998 the NYAIP adjusted its assignments as a result of having over
assigned policies to the Company in 1997 and an overall decrease in the NYAIP's
pool of business.

       Net premiums earned for 1998 were $93,540,000, a decrease of $2,514,000,
or 3%, from $96,054,000 in 1997. Net premiums earned decreased primarily due to
a $2,503,000 (22%) decrease in involuntary earned premiums.

       Net investment income was $13,277,000 in 1998, an increase of 4% from
$12,770,000 in 1997, due to a 5% increase in average invested assets. Realized
investment losses were $2,000 in 1998 compared to $112,000 of realized gains in
1997.

       Net losses and LAE were $65,234,000 for 1998, a decrease of 9% from
$71,627,000 in 1997. The loss and LAE ratio decreased to 69.7% in 1998 from
74.6% in 1997. The decrease in net losses and LAE resulted from the fact that
there was a net decrease of $2,145,000 recorded during 1998 for losses occurring
in prior accident years. The Company recorded an increase to its reserves for
losses related to prior accident years of $4,508,000 in 1997.

       Involuntary automobile insurance business increased the Company's
calendar year loss and LAE ratio by approximately 3.5 and 3.4 percentage points
for the years ended December 31, 1998 and 1997, respectively.

                                       25
<PAGE>   26
       The ratio of policy acquisition costs and other underwriting expenses to
net premiums earned increased to 35.8% in 1998 from 33.4% in 1997 primarily due
to increased agency incentive commissions related to the Company's improved
underwriting results.

       Commissions, premium taxes and other state assessments that vary directly
with the Company's premium volume represented 21.7% and 20.8% of net premiums
earned in 1998 and 1997, respectively. The increase was due primarily to the
increase in agency incentive commissions. Certain other underwriting expenses,
such as salaries, employee benefits, and other operating expenses vary
indirectly with volume and comprise the remainder of the Company's underwriting
expenses.

       The amounts recorded by the Company for income taxes in 1998 and 1997
differed from those calculated using the statutory federal income tax rate
primarily due to tax exempt bond income.

Liquidity and Capital Resources
-------------------------------

       In developing its investment strategy, the Company determines a level of
cash and short-term investments which, when combined with expected cash flow, is
estimated to be adequate to meet expected cash obligations. Historically, the
excess of premiums collected over payments on claims, combined with cash income
from investments, has provided the Company with short-term funds in excess of
normal operating demands for cash.

       The Company's objectives with respect to its investment portfolio include
maximizing total return while protecting policyholders' surplus and maintaining
flexibility. Like other property and casualty insurers, the Company relies on
premiums as a major source of cash, and therefore liquidity. Cash flows from the
Company's investment portfolio, either in the form of interest or principal
payments, are an additional source of liquidity. Because the duration of the
Company's investment portfolio relative to the duration of its liabilities is
closely managed, increases or decreases in market interest rates are not
expected to have a material effect on the Company's liquidity, or its results of
operations.

       The Company generally designates newly acquired fixed maturity
investments as available for sale and carries these investments at fair value.
Unrealized gains and losses related to these investments are recorded as
accumulated other comprehensive income within stockholders' equity. At December
31, 1999, the Company had recorded $1,188,000 of unrealized losses, net of tax,
associated with its fixed maturity investments as accumulated other
comprehensive loss. During 1999 the Company recorded $2,361,000 of unrealized
losses, net of tax, related to its investment portfolio as a component of other
comprehensive income.

       At December 31, 1999, the Company's portfolio of fixed maturity
investments represented 92.4% of invested assets. Management believes that this
level of bond holdings is consistent with the Company's liquidity needs because
it anticipates that cash receipts from net premiums written and investment
income will enable the Company to satisfy its cash obligations. Furthermore, a
portion of the Company's bond portfolio is invested in mortgage-backed and other
asset-backed securities which, in addition to interest income, provide monthly
paydowns of bond principal.

       At December 31, 1999, $106,752,000, or 54.3%, of the Company's fixed
maturity portfolio was invested in mortgage-backed and other asset-backed
securities. The Company invests in a

                                       26
<PAGE>   27
variety of collateralized mortgage obligation ("CMO") products but has not
invested in the derivative type of CMO products such as interest only, principal
only or inverse floating rate securities. All of the Company's CMO investments
have an active secondary market and their effect on the Company's liquidity does
not differ from that of other fixed maturity investments. The Company does not
own any other derivative financial instruments.

       At December 31, 1999, $11,082,000, or 5%, of the Company's investment
portfolio was invested in non-investment grade securities compared to
$6,706,000, or 3%, at December 31, 1998. All of the Company's non-investment
grade securities are currently performing to the Company's purchase
expectations.

        During 1999 the Company repurchased 267,600 shares of its common stock
at an average price of $22.58 and was holding 646,000 shares in treasury as of
December 31, 1999.

       In August 1999, the Company arranged for a $2,000,000 unsecured credit
facility from a bank in the form of a master grid note. Any borrowings under
this facility are payable on demand and carry an interest rate which can be
fixed or variable and is negotiated at the time of each advance. This facility
is available for general working capital purposes and for repurchases of the
Company's common stock. At December 31, 1999, $1,025,000 was outstanding on this
loan.

       As a holding company, the Company is dependent upon cash dividends from
MNH to meet its obligations and to pay any cash dividends. MNH is subject to New
Hampshire insurance laws which place certain restrictions on its ability to pay
dividends without the prior approval of state regulatory authorities. These
restrictions limit dividends to those that, when added to all other dividends
paid within the preceding twelve months, would not exceed 10% of the insurer's
policyholders' surplus as of the preceding December 31st. The maximum amount of
dividends that MNH could pay during any twelve month period ending in 2000
without the prior approval of the New Hampshire Insurance Commissioner is
$5,329,000. MNH paid the maximum allowable dividend to the Company in 1999.
Dividends were paid in January 1999, May 1999 and September 1999, of $2,100,000,
$1,400,000 and $1,600,000, respectively. MNH paid a dividend of $2,200,000 to
the Company on February 14, 2000 and as such is restricted from paying another
dividend to the Company until May, 2000. The Company paid a cash dividend to its
common stockholders of $.05 per share in the first quarter of 1999 and $.10 per
share in the second, third and fourth quarters of 1999. Total dividends paid
amounted to $955,000 in 1999.

       Industry and regulatory guidelines suggest that the ratio of a property
and casualty insurer's annual net premiums written to its statutory surplus
should not exceed 3 to 1. The Company has consistently followed a business
strategy that would allow MNH to meet this 3 to 1 regulatory guideline. MNH's
ratio of net premiums written to statutory surplus for 1999 was 1.8 to 1.

Year 2000
---------

     The Year 2000 issue relates to the way in which information systems
distinguish date data between the twentieth and twenty-first centuries. Also,
many systems and equipment that are not typically thought of as relating to
computers contain embedded hardware or software that may have a time element.
The Company has not encountered any Year 2000 related problems as of the date of
this report.

                                       27
<PAGE>   28
       The Company estimates that its share of the total expenses associated
with becoming Year 2000 compliant approximated $300,000. Approximately $150,000
of the expenses were for external costs, which included $112,000 in outside
consultant expenses and $38,000 for specific upgrades of software to address
Year 2000 compliance, and $150,000 of the expenses have been for internal
resources dedicated to achieving Year 2000 compliance. The Company estimates its
share of costs incurred in 1999 to be $10,000, which has been expensed. There
has not been a material impact on the Company's results of operations or
financial condition as a result of information technology projects being
deferred due to resource constraints caused by the Year 2000 project.

       MNH continues to evaluate the complex issues related to insurance
coverage for losses arising from the various possible situations involving Year
2000 problems and its potential liability to its insureds. The Company believes
that the coverages MNH provides do not extend to the types of losses which are
most likely to occur as a result of Year 2000 problems. For certain classes of
commercial risks, MNH adopted endorsements to its policies that exclude coverage
for losses resulting from Year 2000 problems based on forms provided and filed
for approval with various regulatory authorities by the Insurance Services
Office, Inc. Use of these special endorsements is governed by the law and
regulatory policies of states in which MNH is authorized to do business.

       It is possible, however, that future court interpretations of policy
language based on specific facts, or legislation mandating coverage, could
result in coverage for losses attributable to Year 2000 problems. Such decisions
or legislation could have a material adverse impact on MNH's results of
operations and financial condition. It is also possible that MNH may incur
expenses defending claims for which it is ultimately determined there is no
insurance coverage. MNH has made no provision for reserves for losses or LAE on
claims based on potential Year 2000 problems.

Environmental Claims
--------------------

       MNH, like many other property and casualty insurance companies, is
subject to environmental damage claims asserted by or against its insureds.
Management of the Company is of the opinion that based on various court
decisions throughout the country, such claims should not be recoverable under
the terms of MNH's insurance policies because of either specific or general
coverage exclusions contained in the policies. However, there is no assurance
that the courts will agree with MNH's position in every case, nor can there be
assurance that material claims will not be asserted under policies which a court
will find do not explicitly or implicitly exclude claims for environmental
damages. Management, however, is not aware of any pending claim or group of
claims which would result in a liability that would have a material adverse
effect on the financial condition of the Company or MNH.

Inflation
---------

       Inflation affects the Company, like other companies in the property and
casualty insurance industry, by contributing to higher losses, LAE and operating
costs, as well as greater investment income resulting from the higher interest
rates which can prevail in an inflationary period. Premium rates, however, may
not keep pace with inflation since competitive forces generally limit the
Company's ability to increase premium rates. The Company considers inflationary
trends in estimating its reserves for claims reported and for incurred but not
reported claims.

                                       28
<PAGE>   29
Relationship with Mutual
------------------------

       The Company's and MNH's business and day-to-day operations are closely
aligned with those of Mutual. This is the result of a combination of factors.
Mutual has had a historical ownership interest in the Company and MNH. Prior to
November 1986 MNH was a wholly-owned subsidiary of Mutual. Following the
Company's initial public offering in November 1986 and until a secondary stock
offering in July 1993 the Company was a majority-owned subsidiary of Mutual.
Mutual currently owns 10.0% of the Company's common stock. Under the Management
Agreement, Mutual provides the Company and MNH with all facilities and personnel
to operate their business. The only officers of the Company or MNH who are paid
full time employees are employees of Mutual whose services are purchased under
the Management Agreement. Also, the operation of MNH's insurance business, which
offers substantially the same lines of insurance as Mutual through the same
independent insurance agents, creates a very close relationship among the
companies.

       During 1998, Mutual initiated discussions with the Company concerning
proposals for the acquisition of the Company by Mutual. The Company determined
that the terms proposed by Mutual were inadequate. The Company also determined
that the Management Agreement prevents the Company's shareholders from realizing
the Company's fair value in a sale or merger, and on July 23, 1998 the Company
gave notice to Mutual of its intention to terminate the Management Agreement.
The provisions of the Management Agreement require five years' prior written
notice for its termination. The Company does not expect the notice of
termination to have any material, short-term effect on the Company's operations.
However, the Company believes that the Management Agreement, as currently
written, creates a conflict of interest between the Company and Mutual in their
joint operations and prevents the Company's shareholders from realizing the fair
market value of their shares.

Item 7A.      QUANTITATIVE AND QUALITATIVE DISCLOSURES ABOUT MARKET RISK

Market Risk
-----------

       Market risk represents the potential for loss due to changes in the fair
value of financial instruments. The market risk related to the Company's
financial instruments primarily relates to its investment portfolio. The value
of the Company's investment portfolio of $212,911,000 at December 31, 1999 is
subject to changes in interest rates and to a lesser extent on credit quality.
Further, certain mortgage-backed and asset-backed securities are exposed to
accelerated prepayment risk generally caused by interest rate movements. If
interest rates were to decline, mortgage holders would be more likely to
refinance existing mortgages at lower rates. Acceleration of future repayments
could adversely affect future investment income, if reinvestment of the
accelerated receipts was made in lower yielding securities.

       The table below provides information related to the Company's fixed
maturity investments at December 31, 1999. The table presents cash flows of
principal amounts and related weighted average interest rates by expected
maturity dates. The cash flows are based upon the maturity date or, in the case
of mortgage-backed and asset-backed securities, expected payment patterns.
Actual cash flows could differ from those shown in the table.

                        ---------------------------------


To the Board of Directors
and Stockholders of
Merchants Group, Inc.


In our opinion, the consolidated financial statements listed in the index
appearing under Item 14(a)(1) and (2) present fairly, in all material respects,
the financial position of Merchants Group, Inc. and its subsidiaries at December
31, 1999 and 1998, and the results of their operations and their cash flows for
each of the three years in the period ended December 31, 1999, in conformity
with accounting principles generally accepted in the United States. These
financial statements are the responsibility of the Company's management; our
responsibility is to express an opinion on these financial statements based on
our audits. We conducted our audits of these statements in accordance with
auditing standards generally accepted in the United States which require that we
plan and perform the audit to obtain reasonable assurance about whether the
financial statements are free of material misstatement. An audit includes
examining, on a test basis, evidence supporting the amounts and disclosures in
the financial statements, assessing the accounting principles used and
significant estimates made by management, and evaluating the overall financial
statement presentation. We believe that our audits provide a reasonable basis
for the opinion expressed above.

                   NOTES TO CONSOLIDATED FINANCIAL STATEMENTS
                   ------------------------------------------

1.   Significant Accounting Policies
     -------------------------------

     Principles of consolidation and basis of presentation
     -----------------------------------------------------

     The consolidated financial statements of Merchants Group, Inc. (the
     "Company") include the accounts of the Company, its wholly owned
     subsidiary, Merchants Insurance Company of New Hampshire, Inc. ("MNH"), and
     M.F.C. of New York, Inc., an inactive premium finance company which is a
     wholly owned subsidiary of MNH. MNH is a stock property and casualty
     insurance company domiciled in the state of New Hampshire. MNH offers
     property and casualty insurance to preferred risk individuals and small to
     medium sized businesses in the northeast United States, primarily in New
     York, New Hampshire and New Jersey where a majority of its policies are
     written. As a holding company, the Company has had no operations.

     The consolidated financial statements have been prepared in conformity with
     generally accepted accounting principles ("GAAP") which differ in some
     respects from those followed in reports to insurance regulatory
     authorities. In its Annual Statement filed with regulatory authorities, MNH
     reported policyholders' surplus of $50,576,000 and $53,278,000 at December
     31, 1998 and 1999, respectively. MNH's net income as reported in its Annual
     Statement was $3,481,000 in 1997, $7,367,000 in 1998 and $7,141,000 in
     1999. All significant intercompany balances and transactions have been
     eliminated.

     The preparation of consolidated financial statements in conformity with
     GAAP requires management to make estimates and assumptions that affect the
     reported amounts of assets and liabilities and disclosure of contingent
     assets and liabilities at the date of the financial statements and the
     reported amounts of revenues and expenses during the reporting period.
     Actual results may differ from those estimates.

     Investments
     -----------

     The Company has classified its investments in fixed maturities as either
     held to maturity or available for sale. Fixed maturities classified as held
     to maturity are presented at amortized cost and consist of debt securities
     that management intends and has the ability to hold until maturity. Fixed
     maturities classified as available for sale are presented at fair value and
     consist of debt securities that management may not hold until maturity. All
     preferred stocks are classified as available for sale and are presented at
     fair value. The net aggregate unrealized gain or loss, net of applicable
     income taxes, related to fixed maturities and preferred stock classified as
     available for sale is included as a component of accumulated other
     comprehensive income (loss) in stockholders' equity.

                                      F-9
<PAGE>   55
     Fixed maturities include mortgage backed and asset backed securities which
     are valued using the interest method. The Company estimates prepayments
     utilizing published data when applying the interest method. Periodic
     adjustments to prepayment assumptions are credited or charged to investment
     income.

     Other long-term investments include collateralized mortgage obligation
     residuals, carried at unpaid principal balances which do not vary
     significantly from fair value. Short-term investments, consisting primarily
     of money market mutual funds, have original maturities of three months or
     less and are carried at cost, which approximates fair value. Realized gains
     and losses on the sale of investments are based on the cost of the specific
     investment sold.

     Net premiums earned
     -------------------

     Premiums are recorded as revenue ratably over the terms of the policies
     written (principally one year). Unearned premiums are calculated using a
     monthly pro rata method.

     Deferred policy acquisition costs
     ---------------------------------

     Policy acquisition costs, such as commissions (net of reinsurance
     commissions), premium taxes and certain other underwriting expenses which
     vary directly with premium volume, are deferred and amortized over the
     terms of the related insurance policies. Deferred policy acquisition costs
     do not exceed estimated recoverable amounts after allowing for anticipated
     investment income.

     Reinsurance
     -----------

     Reinsurance assumed from business written through state reinsurance
     facilities has been reflected in unearned premiums, loss reserves, premiums
     earned and losses incurred based on reports received from such facilities.
     Ceded reinsurance premiums, losses and ceding commissions are netted
     against earned premiums, losses and commission expense, respectively.

     Reserve for losses and loss adjustment expenses
     -----------------------------------------------

     Liabilities for unpaid losses and loss adjustment expenses ("LAE") are
     estimates of future payments to be made to settle all insurance claims for
     reported losses and estimates of incurred but not reported losses based
     upon past experience modified for current trends. With the exception of
     workers' compensation losses, loss reserves are not discounted. Estimated
     amounts of salvage and subrogation on paid and unpaid losses are deducted
     from the liability for unpaid claims. The estimated liabilities may be more
     or less than the amount ultimately paid when the claims are settled.
     Management and the Company's independent consulting actuary regularly
     review the estimates of reserves needed and any changes are reflected in
     current operating results.

                                      F-10
<PAGE>   56
     The Company discounts its liability for workers' compensation case reserves
     on a tabular basis, using the National Council on Compensation Insurance
     Workers' Compensation Statistical Plan Table III A at a rate of 3.5%. The
     amount of discount at December 31, 1998 and 1999 is $9,256,000 and
     $8,492,000, respectively. Reserves for losses incurred but not reported and
     for LAE are not discounted.

     Structured settlements have been negotiated for claims on certain insurance
     policies. Structured settlements are agreements to provide periodic
     payments to claimants, and are funded by annuities purchased from various
     life insurance companies. The Company remains primarily liable for payment
     of these claims. Accordingly, a liability and a corresponding deposit in
     the amount $5,764,000 and $6,456,000 at December 31, 1998 and 1999,
     respectively, are recorded in the Company's consolidated balance sheet.

     Income taxes
     ------------

     The Company and its wholly owned subsidiary file a consolidated federal
     income tax return. The Company follows the asset and liability approach to
     account for income taxes, which requires the recognition of deferred tax
     liabilities and assets for the expected future tax consequences of
     temporary differences between the financial statement carrying amounts and
     the tax basis of assets and liabilities.

     Other financial instruments
     ---------------------------

     The fair values of the Company's other financial instruments, principally
     premiums receivable and certain non-insurance related liabilities, do not
     vary significantly from the amounts assigned in these financial statements.

     Insurance-related assessments
     -----------------------------

     In 1997, the American Institute of Certified Public Accountants' Accounting
     Standards Executive Committee issued Statement of Position ("SOP") 97-3,
     "Accounting by Insurance and Other Enterprises for Insurance-Related
     Assessments". The accounting guidance of this SOP focuses on the timing of
     recognition and measurement of liabilities for insurance-related
     assessments. The Company adopted SOP 97-3 in the first quarter of 1999. The
     impact of this adoption was not material to the Company's financial
     position or results of operations.

2.   Related Party Transactions
     --------------------------

     The Company and MNH have no paid employees. Under a management agreement
     Merchants Mutual Insurance Company ("Mutual"), which owns 9.8% of the
     Company's outstanding common stock at December 31, 1999, provides the
     Company and MNH with the facilities, management and personnel required to
     manage their day-to-day business. All underwriting, administrative, claims
     and investment expenses incurred on behalf of Mutual and MNH are shared on
     an allocated cost basis, determined as follows: for underwriting and
     administrative expenses, the respective share of total direct premiums
     written for Mutual and

     MNH serves as the basis of allocation; for claims expenses, the average
     number of outstanding claims is used; investment expenses are shared based
     on each company's share of total invested assets. MNH also pays an annual
     management fee of $50,000 to Mutual. On July 23, 1998, the Company gave
     notice to Mutual of its intent to terminate the management agreement under
     its terms, which termination is effective five years after the date of
     notice.

     MNH's agents are also licensed to sell Mutual's products. The agents are
     informed of the underwriting criteria of each company as well as the
     classes of business that are acceptable to each company. Underwriters
     review each application submitted by an agent to determine which company's
     underwriting criteria the risk meets and then issue a policy in the
     appropriate company. The payable to or receivable from Mutual is
     non-interest bearing and represents the net of premiums collected and loss
     and operating expense payments made by Mutual on behalf of MNH. This
     balance is settled in cash on a monthly basis.

4.   Reinsurance
     -----------

     MNH follows the customary practice of reinsuring a portion of the exposure
     under its policies. Insurance is ceded principally to reduce net liability
     on individual risks and to protect against catastrophic losses. Although
     reinsurance does not legally discharge an insurer from its primary
     liability for the full amount of coverage provided by its policies, it does
     make the assuming reinsurer liable to the insurer to the extent of the
     reinsurance ceded.

     The effect of reinsurance on premiums written and earned for the years
     ended December 31, 1998 and 1999 is as follows:

</TABLE>

     As a result of the reinsurance agreements maintained by MNH, MNH is exposed
     to certain credit risk if one or more of its primary reinsurers were to
     become financially unstable. As of December 31, 1999, MNH has recognized
     amounts to be recovered from its primary reinsurers related to ceded losses
     and ceded unearned premiums totaling $7,725,000. MNH generally does not
     require collateral for reinsurance recoverable.

     In 1998, the Company decreased its reserves for prior years by $2,145,000,
     primarily due to favorable loss experience related to automobile liability
     policies. In 1999, the Company decreased its reserves for prior years by
     $3,749,000 primarily due to favorable loss experience related to workers'
     compensation policies.

6.   Demand Loan
     -----------

     During 1999, the Company arranged for a $2,000,000 unsecured credit
     facility from a bank. Any borrowings under this facility are payable on
     demand and carry an interest rate which can be fixed or variable and is
     negotiated at the time of each advance. This facility is available for
     general working capital purposes and for repurchases of the Company's
     common stock. As of December 31, 1999, $1,025,000 was outstanding under
     this facility and carried a weighted average interest rate of 8.12%.

     Although realization is not assured, based upon the evidence available the
     Company believes that it is more likely than not that the net deferred
     income tax asset will be realized. The amount of the deferred tax asset
     considered realizable, however, could be reduced in the near term if
     estimates of future taxable income are not achieved.

8.   Stockholders' Equity
     --------------------

     Dividends
     ---------

     The Company depends on dividends from its subsidiary, MNH, to pay cash
     dividends to its stockholders and to meet its expenses. MNH is subject to
     New Hampshire state insurance laws which restrict its ability to pay
     dividends without the prior approval of state regulatory authorities. These
     restrictions limit dividends to those that, when added to all other
     dividends paid within the preceding twelve months, would not exceed 10% of
     an insurer's policyholders' surplus as of the preceding December 31. The
     maximum amount of dividends that MNH could pay during any twelve month
     period ending in 2000, without the prior approval of the New Hampshire
     Insurance Commissioner, is $5,328,000.

     Stock option plans
     ------------------

     The Company's stock option plan (the "Plan"), which reserved 200,000 shares
     of common stock for issuance to the Company's and MNH's officers and key
     employees of the Company's affiliate, Mutual, expired in 1996. Under the
     Plan, qualified and non-qualified stock options were granted at amounts not
     less than the fair market value of the Company's stock on the

                                      F-19
<PAGE>   65
     date of grant. Options granted under the Plan have a 10 year life and may
     be exercised in cumulative annual increments of 25% commencing one year
     from the date of grant.

     In accounting for its stock option plans, the Company remains under the
     expense recognition provisions of Accounting Principles Board Opinion No.
     25 "Accounting for Stock Issued to Employees" but follows the disclosure
     provisions of SFAS No. 123 "Accounting for Stock Based Compensation". No
     compensation expense was recognized in 1997, 1998 or 1999 for options
     granted under these plans.

     Had compensation expense for stock options granted under the Company's
     stock option plans been determined based on the fair value at the grant
     date consistent with the method required by SFAS No. 123, the Company's net
     income and earnings per share for the years ended December 31, 1998 and
     1999 would have been as follows:

</TABLE>

     The fair value of each option granted in 1996 was estimated using a
     binomial option pricing model which is a modification of the Black-Scholes
     option pricing model, with the following assumptions for 1996: risk free
     interest rate of 6.25%, volatility of 18.0%, expected dividend yield of
     1.1% and expected life of 10 years.

     A summary of the status of the Company's outstanding options as of December
     31, 1997, 1998 and 1999, and changes during the years ending on those dates

10.  Benefit Programs
     ----------------

     Mutual maintains a capital accumulation plan which is a profit sharing plan
     under Section 401(a) of the Internal Revenue Code that covers all employees
     who have completed six months of service. Mutual matches at least 15% and
     up to 100% of employee contributions, based on the combined net operating
     profits of Mutual and MNH. Additional contributions may be made at the
     discretion of the Board of Directors of Mutual. Under the terms of the
     management agreement, the Company's portion of the total contribution was
     $457,000, $554,000 and $580,000 for the years ended December 31, 1997, 1998
     and 1999, respectively.

11.  Commitments and Contingencies
     -----------------------------

     MNH, like many other property and casualty insurance companies, is subject
     to environmental damage claims asserted by or against its insureds.
     Management is of the opinion that based on various court decisions
     throughout the country, such claims should not be recoverable under the
     terms of MNH's insurance policies because of either specific or general
     coverage exclusions contained in the policies. However, there is no
     assurance that the courts will agree with MNH's position in every case, nor
     can there be assurance that material claims will not be asserted under
     policies which a court will find do not explicitly or implicitly exclude
     claims for environmental damages. Management, however, is not aware of any
     pending claim or group of claims which would result in a liability that
     would have a material adverse effect on the financial condition of MNH.

     In addition to the foregoing, MNH is a defendant in a number of other legal
     proceedings in the ordinary course of its business. Management of the
     Company is of the opinion that the ultimate aggregate liability, if any,
     resulting from such proceedings will not materially affect the financial
     condition of MNH or the Company.
