                                     PART I

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 size 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 9.0% of the Company's issued and
outstanding common stock. The Company and MNH do not have any significant
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 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 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.

Marketing
- ---------

      The Company markets its products through approximately 625 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
Agency Business Managers, or "ABM'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.

      In each of its Strategic Business Centers, the Company uses ABM's who are
trained underwriters. ABM's meet with targeted agents' sales staff on a frequent
basis to underwrite the Company's renewal policies, as well as to solicit and
underwrite policies new to the agent and/or to the Company. ABM'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 ABM'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 the Company.

      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 a two year
loss and allocated loss and loss adjustment expense ("LAE") ratio on business
placed by the agent with the Company. Payments under the Agents' Profit Sharing


<PAGE>   5



Plan for 1998 totaled $2,499,000, or 2.5% of total direct premiums written, and
increased participating agents' commissions received from the Company by
approximately 40%. The Company believes the terms of its 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 87% of the voluntary premiums written by the
Company in 1997 and 1998 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 1998, the Company began development of Merchants MerLink(TM)
system. MerLink(TM) allows 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 15 agents for
private passenger automobile and homeowners' policies. The Company plans to
offer MerLink(TM) capability for commercial insurance policies during the first
half of 1999. 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 yet have such capabilities.

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

      The Company is licensed to issue insurance policies in 13 states,
primarily in the northeastern United States. In 1998, net premiums written
totaled $92,758,000, with 54% of the net premiums written derived from
commercial lines of insurance and 46% 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 size 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  (degree) Homeowners' - properties generally with no losses in the last
         three years and that are less than 30 years old and valued between 
         $75,000 and $300,000.

      o  (degree) 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. During the
years 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 the
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 1999.

      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, 1998 (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.

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 size, 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 and homeowners 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 personal lines underwriters who review the applications and assess

<PAGE>   9


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 $11,325,000, $12,719,000 and $6,036,000 in 1996, 1997
and 1998, respectively, mostly in New York. The Company is unable to predict the
level of its annual involuntary business for 1999 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 meritorious
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 their 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.


<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 an
amount relating to 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 increases in reserves for prior accident year
losses in several years. These increases were necessary because of several
factors, including inaccurate estimation of the extent of liability associated
with a number of claims involving serious injuries and claims handling practices
that did not produce accurate and timely reserve levels for a broad range of
claims. In 1996 and 1997, the Company increased its reserves for prior years by
$6,832,000 and $4,508,000, respectively. These increases were primarily
attributable to higher than anticipated severity of claims on workers'
compensation policies. 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.

      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 1998.

      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, 1998, 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

<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 1999.

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 $27,066,000 of tax-exempt bonds in its investment
portfolio at December 31, 1998. The Company believes these tax-exempt bonds are
of high quality (rated A or better) and offer an after-tax total return greater
than comparable taxable securities.

      At December 31, 1998, the Company had $6,280,000 of short-term investments
with maturities less than 30 days, and $6,706,000 of non-investment grade
securities. These non-investment grade securities represented 3% of its
investment portfolio.

      The table below gives information regarding the Company's investments as
of the dates indicated.

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.

Regulation
- ----------

General
- -------

      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 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. 


<PAGE>   17


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 1999 without the prior approval of the
New Hampshire Insurance Commissioner is $5,058,000.

      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,
1998, investments of MNH having a par value of $1,800,000 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.

      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 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, 1998.

      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


<PAGE>   18


state insurance departments. The ratios relate to leverage, profitability,
liquidity and loss reserve development. One of the Company's ratios as of
December 31, 1998 relating to loss reserve development fell outside of the
acceptable range of ratios. The ratio was outside of the acceptable range due to
the $4,508,000 increase in the provision for losses and LAE recorded in 1997 for
claims occurring in prior years, as discussed in this Item under the heading
"Loss and LAE Reserves". The Company's inability to operate within an acceptable
range of the aforementioned IRIS ratio is not expected to have a material effect
on the Company's business or its operations.

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, 1998, Mutual had 350
full-time equivalent employees. The Company believes that Mutual's relationship
with its employees is satisfactory.

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 


<PAGE>   19


underwriting and/or claims office facilities in Buffalo, Albany and Central
Islip, New York; Bedford, 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.

</TABLE>

       The number of stockholders of record of the Company's Common Stock as of
February 26, 1999 was 122. Securities held by nominees are counted as one
stockholder of record.

       The Company has paid a quarterly cash dividend of $.05 per share 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 1999 without prior
approval of the New Hampshire Insurance Commissioner is $5,058,000.

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

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 written premiums for 1998 were
$92,758,000, a decrease of $4,053,000, or 4%, from $96,811,000 in 1997.

       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 (policies written by the Company
for the first time) 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 New York Automobile Insurance Plan
("NYAIP"), which provides coverage for individuals who are unable to obtain auto
insurance in the voluntary market. During 1998 the Plan 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. 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 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.


<PAGE>   24




       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. 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 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.

1997 Compared to 1996.
- ----------------------

       Total revenues, net premiums earned, net premiums written and direct
premiums written were all substantially unchanged when compared to 1996. Total
revenues for 1997 were $109,150,000, compared to $108,644,000 in 1996. Net
premiums earned for 1997 were $96,054,000, compared to $95,752,000 in 1996. Net
premiums written for 1997 were $96,811,000, compared to $96,622,000 in 1996.
Direct premiums written for 1997 were $101,064,000, compared to $101,007,000 in
1996.

       Voluntary personal lines direct premiums written for 1997 were
$39,415,000, an increase of 5% from $37,616,000 in 1996. Private passenger
automobile direct premiums written, which comprised 79% of total voluntary
personal lines direct premiums written in 1997 and 1996, increased 5% in 1997
compared to 1996. This increase resulted primarily from a 6% increase in average
premium per policy at December 31, 1997 compared to December 31, 1996.
Homeowners direct premiums written increased 4% in 1997 compared to 1996 due to
a 6% increase in average premium per policy.

       Voluntary commercial lines direct premiums written for 1997 were
$51,572,000, a decrease of 7% from $55,467,000 in 1996. This decrease resulted
primarily from a $2,416,000, or 28%, decrease in workers' compensation direct
premiums written and an $804,000, or 5%, decrease in commercial

<PAGE>   25



auto direct premiums written. The decrease in workers' compensation direct
premiums written resulted from the Company's decision in late 1996 to exit
certain unprofitable classes of that business starting in late 1996 and
continuing throughout 1997. The decrease in commercial auto direct premiums
written was due to a 4% decrease in policies in force at December 31, 1997
compared to December 31, 1996, which resulted in part from the Company's
decision not to write certain related workers' compensation policies.

       Involuntary direct premiums written, primarily involuntary private
passenger automobile insurance, which comprised 10% and 8% of total direct
premiums written during 1997 and 1996, respectively, were $10,077,000 for 1997
compared to $7,923,000 in 1996. This 27% increase resulted from increased
assignments from the NYAIP.

       Net investment income was $12,770,000 in 1997, an increase of 9% from
$11,724,000 in 1996, primarily due to a 4% increase in average invested assets
and a 5% increase in the investment portfolio yield. Realized investment gains
were $112,000 in 1997 compared to $996,000 in 1996.

       Losses and LAE were $71,627,000 for 1997, a decrease of 10% from
$79,603,000 in 1996. The loss and LAE ratio decreased to 74.6% in 1997 from
83.1% in 1996. In 1997, the Company recorded increases to its reserve for losses
that occurred prior to 1997, primarily for its workers' compensation line of
business. The net increase in the reserve for prior year losses and LAE was
$4,508,000 and added 4.7 percentage points to the loss and LAE ratio in 1997.
Losses and LAE in 1996 included a $6,896,000 increase in reserves for accidents
that occurred prior to 1996, which added 7.2 percentage points to the loss and
LAE ratio in 1996.

       Losses and LAE in 1996 included $2,200,000 of higher than normal losses
related to unusually severe winter weather that affected the northeastern United
States during the first quarter of 1996. These higher than normal weather
related losses increased the 1996 loss and LAE ratio by 2.3 percentage points.
There were no such higher than normal weather related losses in 1997.

       Involuntary automobile insurance business increased the Company's
calendar year loss and LAE ratio by approximately 3.4 and .7 percentage points
for the years ended December 31, 1997 and 1996, respectively.

       The ratio of policy acquisition costs and other underwriting expenses to
net premiums earned decreased to 33.4% in 1997 from 33.5% in 1996.

       Commissions, premium taxes and other state assessments that vary directly
with the Company's premium volume represented 20.8% and 22.0% of net premiums
earned in 1997 and 1996, 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 Company recorded an income tax provision in 1997 and an income tax
benefit in 1996. The amounts recorded for income taxes 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.

       Net cash provided by operations decreased by $5,234,000, or 55%, from
$9,533,000 in 1997 to $4,299,000 in 1998 primarily due to a $1,981,000 decrease
in the collection of premiums, a $2,144,000 increase in the payment of losses
and LAE and a $1,337,000 increase in income taxes paid.

       Net cash used in investing activities decreased $1,478,000, or 25%, from
$5,905,000 in 1997 to $4,427,000 in 1998. This decrease resulted primarily from
a $6,625,000 net decrease in cash used to purchase fixed maturities, and a
$2,067,000 decrease in cash used to acquire preferred stock, partly offset by a
net increase in cash used to purchase short-term investments ($5,588,000).

       Net cash provided by financing activities increased $3,763,000 from a
$3,629,000 use of cash in 1997 to a $134,000 source of cash in 1998, primarily
due to a $2,048,000 increase in receipts from the Company's affiliate to settle
monthly transactions under the Management Agreement.

       The Company's objectives with respect to its investment portfolio include
maximizing total return while protecting policyholders' surplus, maintaining
flexibility and liquidity, and maintaining a reasonable duration match between
assets and liabilities. 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 carefully 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, 1998, the Company had recorded $1,173,000 of unrealized gains, net of tax,
associated with its fixed maturity investments as accumulated other
comprehensive income. During 1998 the Company recorded $112,000 of unrealized
gains, net of tax, related to its investment portfolio as a component of other
comprehensive income.

       At December 31, 1998, the Company's portfolio of fixed maturity
investments represented 91.9% 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, 1998, $126,250,000, or 63.8%, of the Company's fixed
maturity portfolio was invested in mortgage-backed and other asset- backed
securities. The Company invests in a


<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, 1998, $6,706,000, or 3%, of the Company's investment
portfolio was invested in non-investment grade securities, compared to $861,000,
or .4%, at December 31, 1997.

       During 1998 the Company repurchased 58,800 shares of its common stock at
an average price of $20.26 and was holding 378,400 shares in treasury as of
December 31, 1998.

       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 31. The maximum amount of
dividends that MNH could pay during any twelve month period ending in 1999
without the prior approval of the New Hampshire Insurance Commissioner is
$5,058,000. The Company paid a $.05 per share quarterly cash dividend to its
common stockholders totaling $579,000 in 1998.

       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 1998 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 ("non-IT") that may have a time element.

Under the Management Agreement, Mutual is responsible for the Company's being
Year 2000 compliant. The Company is relying upon the expertise of Mutual's
employees for assuring that the necessary precautions for Year 2000 compliance
are taken. Mutual has advised the Company that the process of preparing all of
its computer systems to be Year 2000 compliant is substantially completed.
Mutual began work on becoming Year 2000 compliant in 1996. The scope of the
project includes: ensuring the compliance of all computer software applications
and operating systems, mainframe, mid-range and personal computers, local and
wide-area networks, and telecommunications equipment; addressing issues related
to non-IT embedded software and equipment; remediation of affected systems and
equipment; and addressing the compliance of key suppliers.

The project has three phases: assessment of systems, equipment and business
relationships affected by the Year 2000 issue; definition of strategies
necessary to address affected systems and relationships; and remediation or
replacement and testing of affected systems, equipment and relationships.


<PAGE>   28




Mutual's target for completing all phases of the project is the fourth quarter
of 1999. Mutual has completed the assessment and strategy phases for all
systems. Mutual began converting to a mid-range computer based policy and claims
system known as "MOST" (Merchants Optimum Services & Technology) in 1994. The
final phase of the conversion to MOST was completed in October 1998. All new
business and policy renewals for all products are now processed on the MOST
system. Mutual has advised the Company that it believes the MOST system, its
mainframe, mid-range and personal computers, and its local area networks are
substantially Year 2000 compliant.

Mutual and the Company depend upon a number of key business partners and
suppliers. As part of its Year 2000 project, Mutual has identified key business
partners, vendors, suppliers, and service providers with whom it and the Company
conduct business, and has made substantial progress in contacting these
organizations to determine their Year 2000 readiness. Based upon the responses
to Mutual's inquiries to these organizations, Mutual has taken and will continue
to take appropriate actions. In certain instances where it may not be possible
to verify with certainty a supplier's Year 2000 compliance (for example, it may
not be possible for Mutual to test the operational ability of its
telecommunications, electricity or gas service suppliers in a Year 2000
environment) and where alternate sources of supply are not feasible, Mutual and
the Company may have to rely on the assurances of the supplier.

The Company estimates that its share of the total expenses associated with
becoming Year 2000 compliant will total approximately $290,000. Approximately
$150,000 of the expenses have been for external costs, which include
approximately $112,000 in outside consultant expenses and $38,000 for specific
upgrades of software to address Year 2000 compliance, and $140,000 of the
expenses have been for internal resources dedicated to achieving Year 2000
compliance. It is estimated that any remaining external or internal costs will
not be material. The Company estimates its share of costs incurred in 1998 to be
$210,000, 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.

Although based on the successful implementation of the MOST system Mutual has
notified the Company that it believes that critical systems are substantially
Year 2000 compliant and that to the best of Mutual's knowledge, the likelihood
that critical systems will have a failure that materially affects operating
results is remote. Mutual also informed the Company that testing will continue
as needed to assure that systems are Year 2000 compliant and that any situation
that develops which needs to be addressed will be corrected by January 1, 2000.
Mutual is continuing to work with third party vendors to assess their ability to
operate in the Year 2000, to assess third-party remediation plans, and to take
steps to identify and transfer support to third party vendors who are Year 2000
compliant. The Company will continue to monitor and assess the reasonably likely
worst case Year 2000 scenario and plans to have contingency plans, as required,
in place by mid-1999. If the Company does not complete its Year 2000 program
prior to the commencement of the Year 2000, if it fails to identify and
remediate all critical Year 2000 problems, or if major suppliers or customers
experience material Year 2000 problems, the Company's results of operations or
financial condition could be materially affected.

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. MNH plans to use coverage
exclusion endorsements based on its evaluation of the potential exposure to Year
2000 problems for certain classes of commercial risks, and has adopted
endorsements to its policies based on forms provided and filed for approval with


<PAGE>   29


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 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.

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 9.0% 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 the Company'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's Directors
who are not affiliated with Mutual


<PAGE>   30



(the "Independent Directors") determined that the terms proposed by Mutual were
inadequate. The Independent Directors 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 year's 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 Independent Directors believe that the Management Agreement, as
currently written, creates conflicts of interest between the Company and Mutual
in their joint operations and prevents the Company's shareholders from realizing
the fair 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 $215,172,000 at December 31, 1998 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, 1998. 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, 1998 and 1997, and the results of their operations and their cash flows for
each of the three years in the period ended December 31, 1998, in conformity
with generally accepted accounting principles. 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 generally accepted auditing
standards 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 $46,006,000 and $50,576,000 at December
     31, 1997 and 1998, respectively. MNH's net income (loss) as reported in its
     Annual Statement was ($2,788,000) in 1996, $3,481,000 in 1997 and
     $7,367,000 in 1998. 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. The
     net aggregate unrealized gain or loss, net of applicable income taxes,
     related to fixed maturities available for sale is included as a component
     of accumulated other comprehensive income in stockholders' equity.

     Fixed maturities include mortgage backed and asset backed securities which
     are valued using the interest method. The Company estimates prepayments
     utilizing published data when 



                                      F-9
<PAGE>   56


     applying the interest method. Periodic adjustments to prepayment
     assumptions are credited or charged to investment income.

     Preferred stocks are carried at fair value. 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.

     The Company discounts its liability for workers' compensation case reserves
     on a tabular basis, using the National Council on Compensation Insurance
     Workers' Compensation 



                                      F-10
<PAGE>   57


     Statistical Plan Table III A at a rate of 3.5%. The amount of discount at
     December 31, 1997 and 1998 is $6,394,000 and $9,256,000, 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 $5,942,000 and $5,764,000 at December 31, 1997 and 1998,
     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.

     Earnings per share

     During 1997, the Company adopted Statement of Financial Accounting
     Standards ("SFAS") No. 128, "Earnings Per Share". This statement prescribes
     new standards for computing and presenting earnings per share ("EPS") and
     makes those standards consistent with international standards. The Company
     has calculated EPS in conformity with the requirements of SFAS No. 128 for
     all periods presented in these financial statements.

     Other comprehensive income

     In 1997, the Financial Accounting Standards Board issued SFAS No. 130,
     "Reporting Comprehensive Income". SFAS No. 130 establishes standards for
     the reporting of comprehensive income in a full set of general-purpose
     financial statements. Comprehensive income as described in SFAS No. 130
     includes net income as well as items under existing accounting standards
     that are reported as adjustments to stockholders' equity. Such adjustments
     to stockholders' equity include unrealized gains and losses on certain
     investments in debt and equity securities. The Company adopted SFAS No. 130
     in the first quarter of 1998.



                                      F-11

     Insurance-Related assessments

     In December 1997, the American Institute of Certified Public Accountants
     ("AICPA") 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 SOP is effective for fiscal years
     beginning after December 15, 1998. The Company estimates that
     implementation of this SOP will not have a material impact on the Company's
     financial condition 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 8.9% of the
     Company's outstanding common stock at December 31, 1998, 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.

    The amortized cost and fair value of fixed maturities by expected maturity
    at December 31, 1998 are shown below. Mortgage and asset backed securities
    are distributed in the table based upon management's estimate of repayment
    periods. Expected maturities will differ from contractual maturities because
    borrowers may have the right to call or prepay obligations with or without
    call or prepayment penalties.

     Discount and premium pertaining to collateralized mortgage obligations are
     amortized over the securities' estimated redemption periods using the
     effective interest method. Yields used to calculate premium or discount are
     adjusted for prepayments quarterly.

     Fixed maturities with a par value of $1,800,000 were on deposit at December
     31, 1998 with various state insurance departments in compliance with

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, 1997 and 1998 is as follows:

     Reinsurance ceded transactions decreased losses and LAE by $5,528,000 and
     $483,000 for the years ended December 31, 1997 and 1998, respectively.

     As a result of the reinsurance agreements maintained by MNH, MNH is exposed
     to certain credit risk if its primary reinsurers were to become financially
     unstable. As of December 31, 1998, MNH has recognized amounts to be
     recovered from its primary reinsurers related to ceded losses and ceded
     unearned premiums totaling $11,259,000. MNH generally does not require
     collateral for reinsurance recoverable.

     In 1997, the Company increased its reserves for prior years by $4,508,000.
     The increase in reserves for prior years recorded in 1997 was primarily
     attributable to higher than anticipated severity of claims on workers'
     compensation policies. 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.

     Although realization is not assured, based upon the available evidence the
     Company believes that it is more likely than not that the net deferred
     federal 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.

7.   Stockholders' Equity

     Preferred and common stock

     Stockholders' equity is comprised of the following:

     Preferred stock, no par value, $424.30 stated value, 10,000 shares
     authorized; no shares issued or outstanding at December 31, 1997 or
     December 31, 1998. The Company also has 3,000,000 shares of $.01 par value
     preferred stock which is authorized and unissued.

     Common stock, $.01 par value, authorized 10,000,000 shares; issued and
     outstanding 2,906,502 shares at December 31, 1997 and 2,851,452 shares at
     December 31, 1998.

     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 1999, without the prior approval of the New Hampshire
     Insurance Commissioner, is $5,058,000. The Company paid a quarterly cash
     dividend to its common stockholders in 1996, 1997 and 1998.

     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 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.

     During 1996, 53,000 options were granted under the Plan at an exercise
     price of $21.00 per share. The weighted average fair value of options
     granted in 1996 was $6.48 per option.

     In March 1994, the Company's Board of Directors approved a stock option
     program providing for the issuance of options to purchase a total of 25,000
     shares of the Company's common stock to certain of MNH's independent
     insurance agents. In June 1994, the Company issued options to purchase
     22,500 shares of common stock under the program at $16.38 per share. These
     options became exercisable on June 1, 1996.

     In 1996, the Company adopted the disclosure provisions of SFAS No. 123
     "Accounting for Stock Based Compensation", but opted to remain under the
     expense recognition provisions of 


                                      F-19
<PAGE>   66


     Accounting Principles Board Opinion No. 25 "Accounting for Stock Issued to
     Employees" in accounting for its stock option plans. No compensation
     expense was recognized in 1996, 1997 or 1998 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, 1997 and
     1998 would have been as follows:

         Pro forma                        $1.38          $2.03
</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, 1996, 1997 and 1998, and changes during the years ending on those dates
     is presented below:

9.   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 one year 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
     $238,000, $457,000 and $554,000 for the years ended December 31, 1996, 1997
     and 1998, respectively.

10.  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.

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

THIS AGREEMENT made and entered into by and between MERCHANTS MUTUAL INSURANCE
COMPANY, Buffalo, New York and MERCHANTS INSURANCE COMPANY OF NEW HAMPSHIRE,
INC., Concord, New Hampshire (hereinafter collectively referred to as "Company")
and AMERICAN RE-INSURANCE COMPANY, a Delaware Corporation with Administrative

PARTIES TO THIS AGREEMENT
- -------------------------

A.       This Agreement is solely between the Company and the Reinsurer. When

         reinsured company named shall be the agent of the other reinsured
         companies as to all matters pertaining to this Agreement. Any payments

B.       The retention of the Company and the liability of the Reinsurer and all
         other benefits accruing to the Company as provided in this Agreement or

         reinsured companies named in this Agreement.

C.       Performance of the obligations of each party to this Agreement shall be
         rendered solely to the other party; however, if the Company becomes
         insolvent, the liability of the Reinsurer shall be modified to the
         extent set forth in the Article entitled INSOLVENCY CLAUSE.

                                  -----------

MANAGEMENT OF CLAIMS AND LOSSES
- -------------------------------

The Company shall investigate and settle or defend all claims and losses. When
requested by the Reinsurer, the Company shall permit the Reinsurer, at the
expense of the Reinsurer, to be associated with the Company in the defense or
control of any claim, loss, or legal proceeding which involves or is likely to
involve the Reinsurer. All payments of claims or losses by the Company within
the limits of its policies which are within the limits set forth in the
applicable Exhibit shall be binding on the Reinsurer, subject to the terms of
this Agreement.

                                   ARTICLE IV
                                   ----------

SALVAGE AND SUBROGATION
- -----------------------

A.       The Reinsurer shall be subrogated, as respects any loss for which the
         Reinsurer shall actually pay or become liable, but only to the extent
         of the amount of payment by or the amount of liability to the
         Reinsurer, to all the rights of the Company against any person or other
         entity who may be legally responsible in damages for said loss. The
         Company hereby agrees to enforce such rights, but in case the Company
         shall refuse or neglect to do so the Reinsurer is hereby authorized and
         empowered to bring any appropriate action in the name of the Company or
         its policyholders, or otherwise to enforce such rights.

B.       Any recoveries, salvages or reimbursements applying to risks covered
         under this Agreement shall always be used to reimburse the excess
         carriers (from the last to the first, beginning with the carrier of the
         last excess), according to their participation, before being used in
         any way to reimburse the Company for its primary loss.

C.       If loss expense is pro rated in the attached Exhibits, then in the
         event there are any 


                                      -4-
<PAGE>   5

         recoveries, salvages or reimbursements recovered subsequent to a loss
         settlement, it is agreed that if the expenses incurred in obtaining
         salvage or other recoveries are less than the amount recovered, such
         expenses shall be borne by each party in the proportion that each party
         benefits from the recoveries. Otherwise, the amount recovered shall
         first be applied to the reimbursement of the expense of recovery and
         the remaining expense shall be borne by the Company and the Reinsurer
         in proportion to the liability of each party for the loss before such
         recovery had been obtained.

D.       If loss expense is included in the ultimate net loss in the attached
         Exhibits, all salvages recoveries or reimbursements, after deduction of
         expenses applicable thereto, recovered or received subsequent to a loss
         settlement under this Agreement shall be applied as if recovered or
         received prior to the aforesaid settlement and all necessary
         adjustments shall be made by the parties hereto, provided always, that
         nothing in this clause shall be construed to mean that losses under
         this Agreement are not recoverable until the Company's ultimate net
         loss has been ascertained.

E.       Expenses hereunder shall exclude all office expenses of the Company and
         all salaries and expenses of its officials and employees. However,
         should litigation be necessary in order to effect recovery and the
         Company use its in-house counsel to conduct or monitor the litigation,
         the Company may include the salary of said in-house counsel while so
         engaged and any direct costs incurred by or on behalf of said in-house
         counsel associated with the litigation.

                                   ARTICLE V

         Reinsurer for special acceptance and, if accepted by the Reinsurer,

                                   ----------

EXTRA CONTRACTUAL OBLIGATIONS AND/OR EXCESS JUDGMENTS
- -----------------------------------------------------

A.       This Agreement shall indemnify the Company, within the limits of this
         Agreement, for Extra Contractual Obligations and/or Excess Judgments
         awarded by a court of competent jurisdiction against the Company that
         arise from policies that are reinsured hereunder. Such Extra
         Contractual Obligation and/or Excess Judgment shall be added to the
         amount of the loss within the Company's policy limit and the sum
         thereof shall be considered one loss subject to the exclusions and
         limitations set forth in this Agreement and its Exhibits.

B.       "Extra Contractual Obligations" are defined as damages paid by the
         Company that are not covered under any other provision of this
         Agreement, including legal costs and expenses in connection therewith,
         that arise as a result of the Company's handling of any claim on the
         policy reinsured hereunder, such liabilities arising because of, but
         not limited to, the following: failure by the Company to settle within
         the policy limit, or by reason of alleged or actual negligence or bad
         faith or alleged fraud in rejecting an offer of settlement or in the
         preparation of the defense or in the trial of any action against its
         insured or in the preparation or prosecution of an appeal consequent
         upon such action.

C.       "Excess Judgments" are defined as those damages paid by the Company
         which amounts are in excess of its policy limits, but otherwise within
         the coverage terms of the policy reinsured hereunder, including legal
         costs and expenses in connection therewith, as a result of an action
         against it by its insured or its insured's assignee to recover damages
         awarded by a court of competent jurisdiction to a third party claimant,
         arising out of, but not limited to, the Company's alleged or actual
         negligence or bad faith or alleged fraud in rejecting a settlement, in
         discharging its duty to defend, in preparing the defense in an action
         against its insured or discharging its duty to prepare or prosecute an
         appeal consequent upon such action.

D.       The date on which an Extra Contractual Obligation and/or an Excess
         Judgment award is incurred by the Company shall be deemed, in all
         circumstances, to have arisen on the same date as the original loss
         occurrence that gave rise to the Extra Contractual Obligation and/or an
         Excess Judgment.

E.       However, this Article shall not apply where the loss has been incurred
         due to the fraud of a member of the Board of Directors or a corporate
         officer of the Company or any other employee of the Company with claims
         settlement authority acting individually or collectively or in
         collusion with any individual or corporation or any other organization
         or party involved in the presentation, defense or settlement of any
         claim covered hereunder.

F.       Recoveries, collectibles or retentions from any form of insurance
         and/or reinsurance, including but not limited to, deductibles or
         self-insured retentions, that protect the Company against claims the
         subject matter of this clause, will inure to the benefit of the
         Reinsurer and shall be deducted from the total amount 


                                      -6-
<PAGE>   7

         of Extra Contractual Obligation and/or Excess Judgment award for
         purposes of determining the amount recoverable hereunder, whether
         collectible or not.

G.       If any provision of this Article shall be rendered illegal or
         unenforceable by the laws, regulations or public policy of any state,
         such provision shall be considered void in such state, but this shall
         not affect the validity or enforceability of any other provision of
         this Agreement or the enforceability of such provision in any other
         jurisdiction.

                                  ARTICLE VII

DECLARATORY JUDGMENT EXPENSES

A.       This Agreement shall indemnify the Company, within the limits of this
         Agreement, for Declaratory Judgment Expenses paid by the Company, as
         provided in this Agreement, under policies reinsured hereunder.

B.       "Declaratory Judgment Expenses" as used herein shall mean legal
         expenses paid by the Company for the investigation, analysis,
         evaluation, and/or resolution of litigation of coverage by the Company
         and any other party to determine if there is coverage to indemnify
         and/or pay to its insured(s) under the policies issued by the Company
         and reinsured hereunder for a specific loss which loss is not
         specifically excluded under this Agreement.

C.       Recoveries from any form of insurance and/or reinsurance that protect
         the Company against claims the subject matter of this clause will inure
         to the benefit of the Reinsurer and shall be deducted from the total
         amount of Declaratory Judgment Expenses for purposes of determining the
         amount recoverable hereunder.

ERRORS AND OMISSIONS
- --------------------

Errors or omissions on the part of the Company shall not invalidate the
reinsurance under this Agreement, provided such errors or omissions are
corrected promptly after discovery thereof, but the liability of the Reinsurer
under this Agreement or any exhibits or endorsements attached thereto shall in
no event exceed the limits specified therein, nor be extended to cover any
risks, perils or classes of insurance generally or specifically excluded

                                   ----------

OFFSET AND SECURITY CLAUSE
- --------------------------

A.       Each party hereto has the right, which may be exercised at any time, to
         offset any amounts, whether on account of premiums or losses or
         otherwise, due from such party to another party under this Agreement or
         any other reinsurance agreement heretofore or hereafter entered into
         between them, against any amounts, whether on account of premiums or
         losses or otherwise due from the latter party to the former party. The
         party asserting the right of offset may exercise this right, whether as
         assuming or ceding insurer or in both roles in the relevant agreement

                                      -7-

         or agreements.

B.       Each party hereby assigns and pledges to the other party (or to each
         other party, if more than one) all of its rights under this Agreement
         to receive premium or loss payments at any time from such other party
         ("Collateral"), to secure its premium or loss obligations to such other
         party at any time under this Agreement and any other reinsurance
         agreement heretofore or hereafter entered into by and between them
         ("Secured Obligations"). If at any time a party is in default under any
         Secured Obligation or shall be subject to any liquidation,
         rehabilitation, reorganization or conservation proceeding, each other
         party shall be entitled in its discretion, to apply, or to withhold for
         the purpose of applying in due course, any Collateral assigned and
         pledged to it by the former party and otherwise to realize upon such
         Collateral as security for such Secured Obligations.

C.       The security interest described herein, and the term "Collateral,"
         shall apply to all payments and other proceeds in respect of the rights
         assigned and pledged. A party's security interest in Collateral shall
         be deemed evidenced only by the counterpart of this Agreement delivered
         to such party.

D.       Each right under this Article is a separate and independent right,
         exercisable, without notice or demand, alone or together with other
         rights, in the sole election of the party entitled thereto, and no
         waiver, delay, or failure to exercise, in respect of any right, shall
         constitute a waiver of any other right. The provisions of this Article
         shall survive any cancellation or other termination of this Agreement.

E.       In the event of the insolvency of a party hereto, offsets shall only be
         allowed in accordance with the laws of the insolvent party's state of
         domicile.

ACCESS TO RECORDS
- -----------------

The Company shall place at the disposal of the Reinsurer and the Reinsurer shall
have the right to inspect, through its authorized representatives, at all
reasonable times during the currency of this Agreement and thereafter, the
books, records and papers of the Company pertaining to the reinsurance provided
hereunder and all claims made in connection therewith.

RESERVES AND TAXES

         hereunder.

B.       The Company will be liable for all taxes on premiums reported to the
         Reinsurer hereunder and will reimburse the Reinsurer for such taxes
         where the Reinsurer is required to pay the same.

INSOLVENCY CLAUSE
- -----------------

(If more than one reinsured company is included in the designation of "Company"
this Article shall apply only to the insolvent company or companies)

In the event of the insolvency of the Company and the appointment of a
conservator, liquidator or statutory successor, the reinsurance provided by this
Agreement shall be payable by the Reinsurer directly to the Company or to its
liquidator, receiver or statutory successor on the basis of the liability of the
Company under the contract or contracts reinsured. Subject to the right of
offset and the verification of coverage, the Reinsurer shall pay its share of
the loss without diminution because of the insolvency of the Company. The
liquidator, receiver or statutory successor of the Company shall give written
notice of the pendency of each claim against the Company on a policy or bond
reinsured within a reasonable time after such claim is filed in the insolvency
proceeding. During the pendency of such claim, the Reinsurer may, at its own
expense, investigate such claim and interpose in the proceeding where such claim
is to be adjudicated any defense or defenses which it may deem available to the
Company, its liquidator or receiver or statutory successor. Subject to court
approval, any expense thus incurred by the Reinsurer shall be chargeable against
the Company as part of the expense of liquidation to the extent of such
proportionate share of the benefit as shall accrue to the Company solely as a
result of the defense undertaken by the Reinsurer. The reinsurance shall be
payable as set forth above except where (i) the Agreement specifies another
payee of such reinsurance in the event of the insolvency of the Company and (ii)
the Reinsurer with the consent of the direct insureds has assumed such policy
obligations of the Company as its direct obligations to the payees under such
policies, in substitution for the obligations of the Company to such payees; or
where the Reinsurer has guaranteed performance of a contract insuring against
physical damage to property for the benefit of mortgagees or other loss payees
named in this Agreement in accordance with Section 1114(c) of the New York
Insurance Law.

ULTIMATE NET LOSS
- -----------------

A.       The term "ultimate net loss" as used herein shall be understood to mean
         the sum actually paid by the Company in settlement of losses for which
         it is held liable, including 90% of any Extra Contractual Obligations
         and/or Excess Judgments and/or Declaratory Judgment Expenses, in
         accordance with their respective articles, after making proper
         deductions for all recoveries, salvages, and claims upon other
         reinsurance which inures to the benefit of the Reinsurer under this
         Agreement whether collectible or not; provided, however, that in the
         event of the insolvency of the Company, "ultimate net loss" shall mean
         the amount of loss which the Company has incurred or for which it is
         liable, and payment by the Reinsurer shall be made to the liquidator,
         receiver or statutory successor of the Company in accordance with the
         provisions of the Article entitled INSOLVENCY CLAUSE.

B.       All expenses incurred by the Company which are included as part of the
         policy limit under the Company's original policies reinsured hereunder
         shall be included in "ultimate net loss" as defined above.

C.       All office expenses of the Company and all salaries and expenses of its
         officials and employees shall be excluded under this Agreement, except
         that the Company may include the costs and expenses of its in-house
         counsel as provided in D. below.

D.       All expenses other than as provided in B. and C. above, including taxed
         court costs, prejudgment and postjudgment interest, and loss expenses
         incurred in investigation, adjustment and litigation, defense and
         settlement of claims made against the Company under its original
         policies reinsured hereunder, including the costs and expenses of the
         Company's in-house counsel while engaged in the litigation of claims
         covered hereunder, shall be apportioned in proportion to the respective
         interests of the parties hereto in the ultimate net loss.

E.       In the event a verdict or judgment is reduced by an appeal or a
         settlement, subsequent to the entry of a judgment, resulting in an
         ultimate saving on such verdict or judgment, or a judgment is reversed
         outright, the expense incurred in securing such final reduction or
         reversal shall (1) be prorated between the Reinsurer and the Company in
         proportion that each benefits from such reduction or reversal and the
         expense incurred up to the time of the original verdict or judgment
         shall be prorated in proportion to each party's interest in such
         verdict or judgment; or (2) when the terms and conditions of the
         Company's original policies reinsured hereunder include expenses as
         part of the policy limit, be added to the Company's ultimate net loss.

B.       Company Retention
         -----------------

         This term shall mean the amount the Company shall retain for its own
         account; however, this requirement shall be satisfied if this amount is
         retained by the Company or its affiliated companies under common

         ----------

         This term shall mean each accident or occurrence or series of accidents
         or occurrences arising out of one event regardless of the number of

         involved, except as modified below:

         (1)      As respects exposures reinsured hereunder other than
                  occupational and other disease or cumulative injury under

                  damage arising out of continuous or repeated exposure to
                  substantially the same general conditions shall be considered
                  as arising out of one occurrence. The date of occurrence shall
                  be deemed to be the following:

                  (i)      As respects a loss involving one or more policies
                           written on an occurrence basis, the date on which

                           claims reported subsequent to such date shall be
                           included in such loss. However, if notice of claim is
                           received and recorded by the Company or the insured
                           during an Extended Reporting Period, the date of
                           occurrence shall be deemed to be the last day of the
                           policy period.

                  (iii)    As respects a loss involving one or more policies
                           written on an occurrence basis and one or more
                           policies written on a claimsmade basis, the date on
                           which bodily injury or property damage occurs, and
                           any related claims reported subsequent to such date
                           shall be included in such loss whether they are
                           covered under occurrence or claims-made policies.

                  injury under workers' compensation or employers' liability
                  policies for which the employer is liable:

                  (i)      Which arises from a specific sudden and accidental
                           event limited in time and place, such occupational or
                           other disease suffered by one or more employees of

                           shall be deemed to be an occurrence within the
                           meaning of this Exhibit, and the date of occurrence
                           shall be deemed to be the date of the beginning of
                           the disability for which compensation is payable if
                           the case is compensable under the Workers'
                           Compensation law; or the date that disability due to
                           said disease actually began if the case is not
                           compensable under the Workers' Compensation law. Each

CONTINGENT COMMISSION
- ---------------------

A.       The Reinsurer shall pay the Company a contingent commission equal to
         50% of the net profit, if any, accruing to the Reinsurer during each
         accounting period defined herein. The first accounting period shall be
         from the effective date of this Agreement through December 31, 2000 and
         each subsequent 36-month period shall be a separate accounting period.
         However, if this Agreement is terminated, the final accounting period
         shall be from the beginning of the then current accounting period
         through the date of termination if this Agreement is terminated on a
         "cutoff" basis, or the end of the runoff period if this Agreement is
         terminated on a "runoff" basis.

B.       The Reinsurer's net profit for each accounting period shall be
         calculated in accordance with the following formula, it being
         understood that a positive balance equals net profit and a negative
         balance equals net loss:

         (1)      Premiums earned for the accounting period; less

         (2)      Ceding commission allowed the Company on premiums earned for
                  the accounting period; less

         (3)      Expenses incurred by the Reinsurer at 12.5% of premiums earned
                  for the accounting period; less

         (4)      Losses incurred for the accounting period; less

         (5)      The Reinsurer's net loss, if any, from the immediately
                  preceding accounting period.

C.       The Company shall calculate and report the Reinsurer's net profit
         within 60 days after the end of each 12-month period within each
         accounting period, within 60 days after the end of each accounting
         period, and within 60 days after the end of each December 31 thereafter
         until all losses subject hereto have been finally settled. Each such
         calculation shall be based on cumulative transactions hereunder from
         the beginning of the accounting period through the date of calculation,
         including the Reinsurer's net loss, if any, from the immediately
         preceding accounting period. As respects the initial calculation
         referred to above, any contingent commission shown to be due the
         Company shall be paid by the Reinsurer as promptly as possible after
         receipt and verification of the Company's report. As respects each
         subsequent calculation, any additional contingent commission shown to
         be due the Company shall be paid by the Reinsurer as promptly as
         possible after receipt and verification


                                      -23-
<PAGE>   24


         of the Company's report. Any return contingent commission shown to be
         due the Reinsurer shall be paid by the Company with its report.

D.       "Premiums earned" as used herein shall mean ceded unearned premiums at
         the beginning of the accounting period, plus ceded net written premiums
         during the period, less ceded unearned premiums at the end of the
         period.

E.       "Losses incurred" as used herein shall mean ceded losses and loss
         adjustment expense paid as of the effective date of calculation, plus
         the ceded reserves for losses and loss adjustment expense outstanding
         as of the same date, all as respects losses occurring during the
         accounting period under consideration.

REINSTATEMENT
- -------------

         A.       First Excess Cover

                  In the event of any portion of the liability under the First
                  Excess Cover being exhausted by loss, the amount so exhausted
                  is automatically reinstated from the time of the occurrence of
                  the loss without payment of additional premium. Nevertheless,
                  the Reinsurer's liability shall not exceed $1,500,000 in
                  respect of all losses from any one occurrence.

         B.       Second Excess Cover

                  In the event of any portion of the liability under the Second
                  Excess Cover being exhausted by loss, the amount so exhausted
                  is automatically reinstated from the time of the occurrence of
                  the loss without payment of additional premium. Nevertheless,
                  the Reinsurer's liability shall not exceed $3,000,000 in
                  respect of all losses from any one occurrence.

         C.       Third Excess Cover

                  The limit of liability of the Reinsurer under the Third Excess
                  Cover with respect to each occurrence shall be reduced by an
                  amount equal to the amount of liability paid by the Reinsurer,
                  but that part of the liability of the Reinsurer that is so
                  reduced shall be automatically reinstated, subject to the
                  maximum payment of $20,000,000 with respect to all occurrences
                  taking place during each calendar year that the Third Excess
                  Cover is in effect. In consideration of this automatic
                  reinstatement, the Company shall pay to the Reinsurer:

                  (a)      For the first $5,000,000 so reinstated an additional
                           reinsurance premium which shall be the product of the
                           annual reinsurance premium set forth in the section
                           entitled REINSURANCE PREMIUM and the amount so
                           reinstated divided by $5,000,000,

                  (b)      For the next two full reinstatements of $5,000,000
                           each, an additional reinsurance premium which shall
                           be the product of 50% of the annual reinsurance
                           premium set forth in the section entitled REINSURANCE
                           PREMIUM and the amount so reinstated divided by
                           $5,000,000.

                  The reinsurance premium so developed for each amount
                  reinstated shall be in addition to the reinsurance premium set
                  forth in the section entitled REINSURANCE PREMIUM, and shall
                  be paid by the Company

                  immediately following loss payment by the Reinsurer.

                  If at the time of loss payment, the adjusted annual
                  reinsurance premium is unknown, calculation of such additional
                  reinsurance premium shall be based upon the annual minimum and
                  deposit reinsurance premium subject to adjustment when the
                  adjusted annual reinsurance premium is established.

                                   ----------

COMMENCEMENT AND TERMINATION
- ----------------------------

         A.       As respects policies written on a claimsmade basis, this
                  Exhibit shall apply to claims received and recorded by the
                  Company or the insured at and after 12:01 A.M., January 1,
                  1998, provided that each such policy includes a specific
                  retroactive date and the occurrence which results in each such
                  claim takes place on or after such retroactive date, and
                  provided further that such retroactive date is on or after the
                  inception date of the first of one or more consecutive
                  claimsmade policies issued by the Company or another
                  insurer(s) to the named insured. However, this Exhibit shall
                  not apply to claims received and recorded by the Company or
                  the insured during any Extended Reporting Period in force at
                  such time and date. As respects policies written on an
                  occurrence basis, this Exhibit shall apply to claims and
                  losses resulting from occurrences taking place at and after
                  12:01 A.M., January 1, 1998.

         B.       This Exhibit may be terminated by either party sending to the
                  other, by registered mail to its principal office, notice
                  stating the time and date when, not less than 90 days after
                  the date of mailing of such notice, termination shall be
                  effective.

         C.       Upon termination of this Exhibit, the Reinsurer's liability
                  hereunder will terminate on a cut-off basis. However, the
                  Company may elect to have the Reinsurer's liability terminate
                  on a run-off basis. The phrases "cut-off basis" and "run-off
                  basis" shall have the meanings set forth below:

                  (1)      Cut-Off Basis:

                           As respects policies written on a claims-made basis,
                           the Reinsurer shall not be liable for claims received
                           and recorded by the Company or the insured at and
                           after the effective time and date of termination,
                           unless such claim is received and recorded by the
                           Company or the insured during an Extended Reporting
                           Period in force or provided under policy conditions
                           in effect at the time and date of termination. As
                           respects policies written on an occurrence basis, the
                           Reinsurer shall not be liable for claims and losses
                           resulting from occurrences taking place at and after
                           the effective time and date of termination.

<PAGE>   29

                  (2)      Run-Off Basis:

                           The Reinsurer shall continue to be liable, with
                           respect to policies in force at the time and date of
                           termination, for occurrences taking place until the
                           expiration, cancellation, or next anniversary date,
                           not to exceed one year, of each such policy of the
                           Company, whichever occurs first, provided that with
                           respect to policies written on a claims-made basis,
                           the claim is received and recorded by the Company or
                           the insured before such expiration, cancellation, or
                           next anniversary date. However, if the Company
                           provides an Extended Reporting Period within one year
                           after the termination date of this Exhibit on any
                           claims-made policy which is in force at such
                           termination date or if an Extended Reporting Period
                           is in force at the time and date of termination, the
                           Reinsurer shall continue to be liable for claims
                           received and recorded by the Company or the insured
                           during such Extended Reporting Period, provided
                           always that the occurrence which results in any such
                           claim takes place prior to the expiration or
                           cancellation date of the policy.

                           For the First and Second Excess Covers, the
                           reinsurance premium for policies in force at the time
                           and date of termination shall be calculated by
                           applying the provisions of the Section entitled
                           REINSURANCE PREMIUM to the quarterly earned premiums
                           that derive from the unearned premium applicable to
                           policies in force at the time and date of
                           termination, provided such reinsurance premium is at
                           least 50% of the reinsurance premium for the prior
                           calendar year. Further, the reinsurance premium for
                           any unlimited Extended Reporting Period provided
                           within one year after the termination date of this
                           Exhibit on any claims-made policy which is in force
                           at such termination date shall be calculated in
                           accordance with the provisions of the Section
                           entitled REINSURANCE PREMIUM. For the Third Excess
                           Cover, the run-off reinsurance premium shall be
                           mutually agreed by the parties.

         D.       When all reinsurance is expired or terminated, the Reinsurer
                  shall return to the Company the reinsurance premium unearned,
                  if any, calculated on the monthly pro rata basis, less the
                  commission previously allowed thereon.

ULTIMATE NET LOSS
- -----------------

A.       The term "ultimate net loss" as used herein shall be understood to mean
         the sum actually paid by the Company in settlement of losses for which
         it is held liable, including 90% of any Extra Contractual Obligations
         and/or Excess Judgments and/or Declaratory Judgment Expenses, in
         accordance with their respective articles, after making proper
         deductions for all recoveries, salvages, and claims upon other
         reinsurance which inures to the benefit of the Reinsurer under this
         Agreement whether collectible or not; provided, however, that in the
         event of the insolvency of the Company, "ultimate net loss" shall mean
         the amount of loss which the Company has incurred or for which it is
         liable, and payment by the Reinsurer shall be made to the liquidator,
         receiver or statutory successor of the Company in accordance with the
         provisions of the Article entitled INSOLVENCY CLAUSE.

B.       All expenses incurred by the Company which are included as part of the
         policy limit under the Company's original policies reinsured hereunder
         shall be included in "ultimate net loss" as defined above.

C.       All office expenses of the Company and all salaries and expenses of its
         officials and employees shall be excluded under this Agreement, except
         that the Company may include the costs and expenses of its in-house
         counsel as provided in D. below.

D.       All expenses other than as provided in B. and C. above, including taxed
         court costs, prejudgment and postjudgment interest, and loss expenses
         incurred in investigation, adjustment and litigation, defense and
         settlement of claims made against the Company under its original
         policies reinsured hereunder, including the costs and expenses of the
         Company's in-house counsel while engaged in the litigation of claims
         covered hereunder, shall be apportioned in proportion to the respective
         interests of the parties hereto in the ultimate net loss.

E.       In the event a verdict or judgment is reduced by an appeal or a
         settlement, subsequent to the entry of a judgment, resulting in an
         ultimate saving on such verdict or judgment, or a judgment is reversed
         outright, the expense incurred in securing such final reduction or
         reversal shall (1) be prorated between the Reinsurer and the Company in
         proportion that each benefits from such reduction or reversal and the
         expense incurred up to the time of the original verdict or judgment
         shall be prorated in proportion to each party's interest in such
         verdict or judgment; or (2) when the terms and conditions of the
         Company's original policies reinsured hereunder include expenses as
         part of the policy limit, be added to the Company's ultimate net loss.

F.       Recoveries from catastrophe reinsurance shall be deemed not to reduce
         the amount required with respect to the Company Retention.

COMMENCEMENT AND TERMINATION
- ----------------------------

A.       This Exhibit shall apply to new and renewal policies of the Company
         becoming effective at and after 12:01 A.M., January 1, 1998, and to
         policies of the Company in force at 12:01 A.M., January 1, 1998, with
         respect to claims or losses resulting from occurrences taking place at
         and after the aforesaid time and date.

B.       This Exhibit may be terminated by either party sending to the other, by
         registered mail to its principal office, notice stating the time and
         date when, not less than 90 days after the date of mailing of such
         notice, termination shall be effective.

C.       Upon termination of this Exhibit, the Reinsurer's liability hereunder
         will terminate on a cut-off basis. However, the Company may elect to
         have the Reinsurer's liability terminate on a run-off basis. The
         phrases "cut-off basis" and "run-off basis" shall have the meanings set
         forth below:

         (1)      Cut-Off Basis:

                  The Reinsurer shall not be liable for claims and losses
                  resulting from occurrences taking place at and after the
                  effective time and date of termination.

         (2)      Run-Off Basis:

                  The Reinsurer shall continue to be liable, with respect to
                  policies in force at the time and date of termination, for
                  occurrences taking place until the expiration, cancellation,
                  or next anniversary date, not to exceed one year, of each such
                  policy of the Company, whichever occurs first.

                  The reinsurance premium for policies in force at the time and
                  date of termination shall be calculated by applying the
                  provisions of the Section entitled REINSURANCE PREMIUM to the
                  quarterly earned premiums that derive from the unearned
                  premium applicable to policies in force at the time and date
                  of termination, provided such reinsurance premium is at least
                  50% of the reinsurance premium for the prior calendar year.

D.       When all reinsurance is expired or terminated, the Reinsurer shall
         return to the Company the reinsurance premium unearned, if any,
         calculated on the monthly pro rata basis.

     Aggregate Limit of Insurance Endorsement CP 04 07 (Ed., 4/86) or as
     subsequently amended or by any similar endorsement affording such coverage;

     Pollutant clean up or removal, including time element coverage associated
     therewith, under any commercial property policy or any inland marine policy
     written by the Company which does not contain ISO Changes- Pollutants
     Endorsement CP 01 86 (Ed. 4/86) or as subsequently amended; however this
     exclusion does not apply to any risk located in a jurisdiction which has
     not approved the Insurance Services Office exclusion or where other
     regulatory constraints prohibit the Company from attaching such
     endorsement. If the Company elects to file an endorsement independent of
     ISO, such endorsement will be deemed a suitable substitute provided the
     Company has submitted the wording to the Reinsurers and received the
     Reinsurers' prior approval.


ARTICLE 5 - NET RETAINED LINES

This Agreement applies only to that portion of any policy which the Company
retains net for its

own account, and in calculating the amount of any loss hereunder and also in
computing the amount or amounts in excess of which this Agreement attaches, only
loss or losses in respect of that portion of any policy which the Company
retains net for its own account shall be included.


                                     Page 9

<PAGE>   10


The amount of the Reinsurer's liability hereunder in respect of any loss or
losses shall not be increased by reason of the inability of the Company to
collect from any other reinsurer(s), whether specific or general, any amounts
which may have become due from such reinsurer(s), whether such inability arises
from the insolvency of such other reinsurer(s) or otherwise.

ARTICLE 6 - ULTIMATE NET LOSS
- -----------------------------

The term "ultimate net loss" as used herein shall be understood to mean the sum
actually paid by the Company in settlement of losses for which it is liable,
after making proper deductions for all other reinsurance or insurance which
inures to the benefit of the Reinsurer under this Agreement, whether collectible
or not, and all salvages and all recoveries, and shall include all expenses
incurred by the Company in the settlement or defense of claims including the
salaries and expenses of salaried adjusters but excluding the office expenses of
the Company and the salaries and expenses of its other employees; provided,
however, that in the event of the insolvency of the Company, "ultimate net loss"
shall mean the amount of loss and expense which the Company has incurred or for
which it is liable, and payment by the Reinsurer shall be made to the
liquidator, receiver or statutory successor of the Company in accordance with
the provisions of the Insolvency Article of this Agreement.

ARTICLE 7 - LOSS OCCURRENCE
- ---------------------------
NMA 2244 Amended (BRMA 27a)

A. The term "Loss Occurrence" shall mean the sum of all individual losses
directly occasioned by any one disaster, accident or loss or series of
disasters, accidents or losses arising out of one event which occurs within the
area of one state of the United States or province of Canada and states or
provinces contiguous thereto and to one another. However, the duration and
extent of any one "Loss Occurrence" shall be limited to all individual losses
sustained by the Company occurring during any period of 168 consecutive hours
arising out of and directly occasioned by the same event except that the term
"Loss Occurrence" shall be further defined as follows:

         (i) As regards windstorm, hail, tornado, hurricane, cyclone, including
         ensuing collapse and water damage, all individual losses sustained by
         the Company occurring during any period of 72 consecutive hours arising
         out of and directly occasioned by the same event. However, the event
         need not be limited to one state or province or states or provinces
         contiguous thereto.

         (ii) As regards riot, riot attending a strike, civil commotion,
         vandalism and malicious mischief, all individual losses sustained by
         the Company occurring during any period of 72 consecutive hours within
         the area of one municipality or county and the municipalities or
         counties contiguous thereto arising out of and directly occasioned by
         the same event. The maximum duration of 72 consecutive hours may be
         extended in respect of individual losses which occur beyond such 72
         consecutive hours during the continued occupation of an assured's
         premises by strikers, provided such occupation commenced during the
         aforesaid period.


                                    Page 10

<PAGE>   11


         (iii) As regards earthquake (the epicenter of which need not
         necessarily be within the territorial confines referred to in the
         opening paragraph of this Article) and fire following directly
         occasioned by the earthquake, only those individual fire losses which
         commence during the period of 168 consecutive hours may be included in
         the Company's "Loss Occurrence."

         (iv) As regards "Freeze," only individual losses directly occasioned by
         collapse, breakage of glass and water damage (caused by bursting of
         frozen pipes and tanks) may be included in the Company's "Loss
         Occurrence."

B. For all "Loss Occurrences," other than (ii) above, the Company may choose the
date and time when any such period of consecutive hours commences, provided that
it is not earlier than the date and time of the occurrence of the first recorded
individual loss sustained by the Company arising out of that disaster, accident
or loss and provided that only one such period of 168 consecutive hours shall
apply with respect to one event, except for any "Loss Occurrence" referred to in
sub-paragraph (i) above where only one such period of 72 consecutive hours shall
apply with respect to one event.

C. As respects those "Loss Occurrences" referred to in (ii) above, the Company
may choose the date and time when any such period of consecutive hours
commences. If the disaster, accident or loss occasioned by the event is of
greater duration than 72 consecutive hours, then the Company may divide that
disaster, accident or loss into two or more "Loss Occurrences" provided no
periods overlap and no individual loss is included in more than one such period
and provided that no period commences earlier than the date and time of the
occurrence of the first recorded individual loss sustained by the Company
arising out of that disaster, accident or loss.

D. No individual losses occasioned by an event that would be covered by 72 hours
clauses may be included in any "Loss Occurrence" claimed under the 168 hours
provision.

ARTICLE 8 - RETENTION AND LIMIT
- -------------------------------

A. As respects each Excess Layer of reinsurance coverage provided by this
Agreement, the Company shall retain the amount of ultimate net loss, shown as
the Company's Retention for each Excess Layer in SCHEDULE A attached hereto,
arising out of each and every loss occurrence. The Reinsurer shall then be
liable, as respects its participation in the Excess Layer, for the amount by
which such ultimate net loss exceeds the Company's Retention, each and every
loss occurrence, but the limit of liability of the Reinsurer shall not exceed
the amount shown in SCHEDULE A as Reinsurer's Limit of Liability, each and every
loss occurrence during the term of this Agreement.

B. In addition to the Company's Retention, the Company will retain net for its
own account, with respect to each loss occurrence, the remaining 5% in each
Excess Layer.


                                    Page 11

<PAGE>   12



ARTICLE 9 - REINSTATEMENT

A. In the event of a claim attaching to this Agreement, it is understood and
agreed that the amount of liability hereunder shall be reduced from the
commencement of the loss occurrence giving rise to such claim by the sum payable
on such claim, but any amount so exhausted shall be reinstated from the time of
the loss occurrence. Reinstatements of the limits hereunder for each Excess
Layer; i.e., the liability of the Reinsurer under each Excess Layer of
reinsurance coverage hereunder, shall not exceed the Reinsurer's Limit of
Liability as shown in SCHEDULE A with respect to each and every loss occurrence
under such Excess Layer, and shall be further limited to a Reinsurer's Maximum
Annual Limit as shown in SCHEDULE A for all loss occurrences under such Excess
Layer during the term of this Agreement.

B. For each amount so reinstated, the Company shall pay to the Reinsurer an
additional premium calculated as shown in SCHEDULE A. Any such additional
premium shall be immediately payable at the time the loss giving rise to such
reinstatement is settled; however, such additional premium shall be based on the
Deposit premium with adjustment as required at the end of the term of this
Agreement, when the actual reinsurance premium hereunder shall be finally
determined.

ARTICLE 10 - REINSURANCE PREMIUM
- --------------------------------

A. The premium to be paid by the Company to the Reinsurer hereunder shall be
calculated by applying the Premium Rate, for each Excess Layer shown in SCHEDULE
A, to the Company's subject gross net earned premium income during the term of
this Agreement.

B. The Deposit Premium, for each Excess Layer as shown in SCHEDULE A, shall be
payable by the Company quarterly, in advance, in equal installments each on
January 1, April 1, July 1, and October 1, 1998. As promptly as possible after
the termination of this Agreement, the Company shall render a statement to the
Reinsurer showing the actual reinsurance premium due hereunder, calculated as
set forth in paragraph A. above. Subject to a Minimum Premium for each Excess
Layer as shown in SCHEDULE A, the difference between the actual reinsurance
premium and the Deposit Premium shall be paid by the debtor party to the
creditor party.

ARTICLE 11 - REPORTS AND REMITTANCES
- ------------------------------------

Within 60 days following expiration of this Agreement, the Company will furnish
the Reinsurers with a report of reinsurance premium due them for that period.
Such report will show and properly segregate the Company's subject premium to
which the reinsurance rate applies as well as contain such other information as
may be required by the Reinsurers for completion of their NAIC interim and/or
annual statements. The actual reinsurance premium will be calculated in
accordance with ARTICLE 10 - REINSURANCE PREMIUM, and any balance shown to be
due the Reinsurers will be remitted with said report. Any balance shown to be
due the Company will be payable within 30 days following receipt of the report
by the Reinsurers.

ARTICLE 12 - CURRENCY

shall be construed to mean United States Dollars and all transactions under this
Agreement shall be in United States Dollars.

B. Amounts paid or received by the Company in any other currency shall be
converted to United States Dollars at the rate of exchange at the date such
transaction is entered on the books of the Company.

ARTICLE 13 - TAXES
- ------------------
(BRMA 50B)

In consideration of the terms under which this Agreement is issued, the Company
will not claim a deduction in respect of the premium hereon when making tax
returns, other than income or profits tax returns, to any state or territory of
the United States of America or the District of Columbia.

ARTICLE 14 - FEDERAL EXCISE TAX
- -------------------------------
(BRMA 17A)

(Applicable to those reinsurers, excepting Underwriters at Lloyd's London and
other reinsurers exempt from Federal Excise Tax, who are domiciled outside the
United States of America.)

A. The Reinsurer has agreed to allow for the purpose of paying the Federal
Excise Tax the applicable percentage of the premium payable hereon (as imposed
under Section 4371 of the Internal Revenue Code) to the extent such premium is
subject to the Federal Excise Tax.

B. In the event of any return of premium becoming due hereunder the Reinsurer
will deduct the applicable percentage from the return premium payable hereon and
the Company or its agent should take steps to recover the tax from the United
States Government.

ARTICLE 15 - ERRORS AND OMISSIONS
- ---------------------------------
(BRMA 12A)

Any inadvertent delay, omission or error shall not be held to relieve either
party hereto from any liability which would attach to it hereunder if such
delay, omission or error had not been made, provided such omission or error is
rectified upon discovery.

ARTICLE 16 - LOSS NOTICE
- ------------------------
(BRMA 26B)

The Company shall advise the Reinsurer promptly of all losses which, in the
opinion of the Company, may result in a claim hereunder and of all subsequent
developments thereto which, in the opinion of the Company, may materially affect
the position of the Reinsurer.

ARTICLE 17 - LOSS SETTLEMENTS

(BRMA 29E)

All loss settlements made by the Company, under policies subject hereto, whether
under policy terms and conditions or by way of compromise, shall be binding upon

agrees to pay or allow, as the case may be, its share of each such settlement in
accordance with this Agreement.

ARTICLE 18 - OFFSET
- -------------------
(BRMA 36B)

The Company and the Reinsurer may offset any balance or amount due from one
party to the other under this Agreement or any other contract heretofore or
hereafter entered into between the Company and the Reinsurer, whether acting as
assuming reinsurer or ceding company. However, in the event of the insolvency of
any party hereto, offset shall only be allowed in accordance with applicable 
law.

ARTICLE 19 - ACCESS TO RECORDS
- ------------------------------
(BRMA 1D)

The Reinsurer or its designated representatives shall have access at any
reasonable time to all records of the Company which pertain in any way to this

ARTICLE 20 - UNAUTHORIZED REINSURANCE
- -------------------------------------
(BRMA 55D)

(Applies only to a Reinsurer who does not qualify for full credit with any
insurance regulatory authority having jurisdiction over the Company's
reserves.)A. As regards policies or bonds issued by the Company coming within
the scope of this Agreement, the Company agrees that when it shall file with the
insurance regulatory authority or set up on its books reserves for losses
covered hereunder which it shall be required by law to set up, it will forward
to the Reinsurer a statement showing the proportion of such reserves which is
applicable to the Reinsurer. The Reinsurer hereby agrees to fund such reserves
in respect of known outstanding losses that have been reported to the Reinsurer
and allocated loss adjustment expense relating thereto, and losses and allocated
loss adjustment expense paid by the Company but not recovered from the
Reinsurer, as shown in the statement prepared by the Company (hereinafter
referred to as "Reinsurer's Obligations") by funds withheld, cash advances or a
Letter of Credit. The Reinsurer shall have the option of determining the method
of funding provided it is acceptable to the insurance regulatory authorities
having jurisdiction over the Company's reserves.

B. When funding by a Letter of Credit, the Reinsurer agrees to apply for and
secure timely delivery to the Company of a clean, irrevocable and unconditional
Letter of Credit issued by a bank and containing provisions acceptable to the
insurance regulatory authorities having jurisdiction over the Company's reserves
in an amount equal to the Reinsurer's proportion of said reserves. Such Letter
of Credit shall be issued for a period of not less than one year, and shall be
automatically extended for one year from its date of expiration or any future
expiration date unless thirty (30) days (sixty (60) days where required by
insurance regulatory authorities) 

                                    Page 14


<PAGE>   15

prior to any expiration date the issuing bank shall notify the Company by
certified or registered mail that the issuing bank elects not to consider the
Letter of Credit extended for any additional period.

C. The Reinsurer and Company agree that the Letters of Credit provided by the
Reinsurer pursuant to the provisions of this Agreement may be drawn upon at any
time, notwithstanding any other provision of this Agreement, and be utilized by
the Company or any successor, by operation of law, of the Company including,
without limitation, any liquidator, rehabilitator, receiver or conservator of
the Company for the following purposes, unless otherwise provided for in a
separate Trust Agreement:

         (a) to reimburse the Company for the Reinsurer's Obligations, the
         payment of which is due under the terms of this Agreement and which has
         not been otherwise paid;

         (b) to make refund of any sum which is in excess of the actual amount
         required to pay the Reinsurer's Obligations under this Agreement;

         (c) to fund an account with the Company for the Reinsurer's
         Obligations. Such cash deposit shall be held in an interest bearing
         account separate from the Company's other assets, and interest thereon
         not in excess of the prime rate shall accrue to the benefit of the
         Reinsurer;

         (d) to pay the Reinsurer's share of any other amounts the Company
         claims are due under this Agreement.

B. In the event the amount drawn by the Company on any Letter of Credit is in
excess of the actual amount required for (a) or (c), or in the case of (d), the
actual amount determined to be due, the Company shall promptly return to the
Reinsurer the excess amount so drawn. All of the foregoing shall be applied
without diminution because of insolvency on the part of the Company or the
Reinsurer.

C. The issuing bank shall have no responsibility whatsoever in connection with
the propriety of withdrawals made by the Company or the disposition of funds
withdrawn, except to ensure that withdrawals are made only upon the order of
properly authorized representatives of the Company.

D. At annual intervals, or more frequently as agreed but never more frequently
than quarterly, the Company shall prepare a specific statement of the
Reinsurer's Obligations, for the sole purpose of amending the Letter of Credit,
in the following manner:

         (a) If the statement shows that the Reinsurer's Obligations exceed the
         balance of credit as of the statement date, the Reinsurer shall, within
         thirty (30) days after receipt of notice of such excess, secure
         delivery to the Company of an amendment to the Letter of Credit
         increasing the amount of credit by the amount of such difference.


                                    Page 15

<PAGE>   16

         (b) If, however, the statement shows that the Reinsurer's Obligations
         are less than the balance of credit as of the statement date, the
         Company shall, within thirty (30) days after receipt of written request
         from the Reinsurer, release such excess credit by agreeing to secure an
         amendment to the Letter of Credit reducing the amount of credit
         available by the amount of such excess credit.

ARTICLE 21 - SERVICE OF SUIT
- ----------------------------
(BRMA 49A)

(This Article only applies to reinsurers domiciled outside of the United States
and/or unauthorized in any state, territory, or district of the United States
having jurisdiction over the Company).

A. It is agreed that in the event of the failure of the Reinsurer hereon to pay
any amount claimed to be due hereunder, the Reinsurer hereon, at the request of
the Company, will submit to the jurisdiction of a court of competent
jurisdiction within the United States. Nothing in this Article constitutes or
should be understood to constitute a waiver of the Reinsurer's rights to
commence an action in any court of competent jurisdiction in the United States,
to remove an action to a United States District Court, or to seek a transfer of
a case to another court as permitted by the laws of the United States or of any
state in the United States. It is further agreed that service of process in such
suit may be made upon Messrs. Mendes & Mount, 750 Seventh Avenue, New York, New
York l00l9, U.S.A., and that in any suit instituted, the Reinsurer will abide by
the final decision of such court or of any appellate court in the event of an
appeal.

B. The above-named are authorized and directed to accept service of process on
behalf of the Reinsurer in any such suit and/or upon the request of the Company
to give a written undertaking to the Company that they will enter a general
appearance upon the Reinsurer's behalf in the event such a suit shall be
instituted.

C. Further, pursuant to any statute of any state, territory or district of the
United States which makes provision therefore, the Reinsurer hereon hereby
designates the Superintendent, Commissioner or Director of Insurance or other
officer specified for that purpose in the statute, or his successor or
successors in office, as its true and lawful attorney upon whom may be served
any lawful process in any action, suit or proceeding instituted by or on behalf
of the Company or any beneficiary hereunder arising out of this Agreement of
reinsurance, and hereby designates the above-named as the person to whom the
said officer is authorized to mail such process or a true copy thereof.

ARTICLE 22 - INSOLVENCY
- -----------------------

The reinsurance provided by this Agreement shall be payable by the Reinsurer
directly to the Company or to its liquidator, receiver or statutory successor on
the basis of the liability of the Company under the contract or contracts
reinsured. Subject to the right of offset and the verification of coverage, the
Reinsurer shall pay its share of the loss without diminution because of the
insolvency of the Company. In the event of the insolvency of the Company, the
liquidator, receiver or statutory successor of the Company shall give written
notice of the 

                                    Page 16

<PAGE>   17

pendency of each claim against the Company on a policy or bond reinsured within
a reasonable time after such claim is filed in the insolvency proceeding. During
the pendency of such claim, the Reinsurer may, at its own expense, investigate
such claim and interpose in the proceeding where such claim is to be adjudicated
any defense or defenses which it may deem available to the Company, its
liquidator or receiver or statutory successor. Subject to court approval, any
expense thus incurred by the Reinsurer shall be chargeable against the Company
as part of the expense of liquidation to the extent of such proportionate share
of the benefit as shall accrue to the Company solely as a result of the defense
undertaken by the Reinsurer. The reinsurance shall be payable as set forth above
except where this Agreement specifically provides for the payment of reinsurance
proceeds to another party in the event of the insolvency of the Company.

ARTICLE 23 - ARBITRATION
- ------------------------
(BRMA 6B)

A. As a condition precedent to any right of action hereunder, any irreconcilable
dispute between the parties to this Agreement will be submitted for decision to
a board of arbitration composed of two arbitrators and an umpire meeting in
Buffalo, New York.

B. Arbitration shall be initiated by the delivery of a written notice of demand
for arbitration by one party to the other within a reasonable time after the
dispute has arisen.

C. The members of the board of arbitration shall be active or retired
disinterested officials of insurance or reinsurance companies, or Underwriters
at Lloyd's, London, not under the control or management of either party to this
Agreement. Each party shall appoint its arbitrator, and the two arbitrators
shall choose an umpire before instituting the hearing. If the respondent fails
to appoint its arbitrator within four (4) weeks after being requested to do so
by the claimant, the latter shall also appoint the second arbitrator. If the two
arbitrators fail to agree upon the appointment of an umpire within four (4)
weeks after their nominations, each of them shall name three of whom the other
shall decline two, and the decision shall be made by drawing lots. The claimant
shall submit its initial brief within forty-five (45) days from appointment of
the umpire. The respondent shall submit its brief within forty-five (45) days
thereafter, and the claimant may submit a reply brief within thirty (30) days
after filing of the respondent's brief.

D. The board shall make its decision with regard to the custom and usage of the
insurance and reinsurance business. The board shall issue its decision in
writing based upon a hearing in which evidence may be introduced without
following strict rules of evidence but in which cross-examination and rebuttal
shall be allowed. The board shall make its decision within sixty (60) days
following the termination of the hearings unless the parties consent to an
extension. The majority decision of the board shall be final and binding upon
all parties to the proceeding. Judgment may be entered upon the award of the
board in any court having jurisdiction.

E. If more than one reinsurer is involved in the same dispute, all such
reinsurers shall constitute and act as one party for purposes of this clause,
and communications shall be made by the Company to each of the reinsurers
constituting the one party provided, however, that nothing therein shall impair
the rights of such reinsurers to assert several rather than joint defenses or
claims, nor be construed as changing the liability of the reinsurers under the
terms of this Agreement from several to joint.

                                    Page 17

<PAGE>   18

F. Each party shall bear the expense of its own arbitrator and shall jointly and
equally bear with the other party the expense of the umpire. The remaining costs
of the arbitration proceedings shall be allocated by the board.

ARTICLE 24 - INTERMEDIARY

AM-RE Brokers, Inc. is hereby recognized as the Intermediary negotiating this
Agreement for all business hereunder. All communications (including but not
limited to notices, statements, premium, return premium, commissions, taxes,
losses, loss adjustment expense, salvages and loss settlements) relating thereto
shall be transmitted to the Company or the Reinsurer through AM-RE Brokers,
Inc., 685 College Road East, Princeton, New Jersey 08543-5212. Payments by the
Company to the Intermediary shall be deemed to constitute payment to the
Reinsurer. Payments by the Reinsurer to the Intermediary shall be deemed to
constitute payment to the Company only to the extent that such payments are
actually received by the Company.

                          EMPLOYEE RETENTION AGREEMENT
                          ----------------------------



         This AGREEMENT ("Agreement"), dated as of March 1, 1999, is by and
between EDWARD M. MURPHY, residing at 256 Louvaine Drive, Buffalo, New York
14223 (the "Executive") and MERCHANTS MUTUAL INSURANCE COMPANY, a New York
mutual insurance company with its principal office at 250 Main Street, Buffalo,
New York 14202 (the "Company").

                                    RECITALS:

         WHEREAS, the Company is responsible for managing the business of
Merchants Group, Inc. ("MGI") and MGI's wholly-owned subsidiary, Merchants
Insurance Company of New Hampshire, Inc. ("MNH"), under a Management Agreement
dated September 29, 1986 by and among the Company, MGI and MNH (the "Management

         WHEREAS, MGI has given notice to the Company that it will terminate the
Management Agreement no later than at the end of the required five-year notice
period; and

         WHEREAS, the Executive is a key employee of the Company; and

         WHEREAS, the Company believes that the Executive's continued employment
with the Company will enhance the Company's ability to continue to manage the
business of the Company, MGI and MNH throughout the period prior to the
effective date of the termination of the Management Agreement; and

         WHEREAS, the Company believes that the Executive's continued employment
with the Company will be in the collective best interests of the Company, MGI
and MNH; and

         WHEREAS, the Company believes that by extending certain financial
incentives to the Executive it will assist the Company in retaining the services
of the Executive throughout the period prior to the effective date of the
termination of the Management Agreement; and

         WHEREAS, the Executive and the Company desire to enter into this
Agreement in order to provide for such financial incentives.

         NOW, THEREFORE, in consideration of the promises and the mutual
agreements herein contained, the adequacy and sufficiency of which are hereby

<PAGE>   3



         1.       SALARY CONTINUATION AND BENEFITS.
                  ---------------------------------

                  (a) The purpose of this paragraph 1 is to provide the
Executive with a continuation of salary and certain benefits in the event it is
necessary or advisable for the Company, through no fault of the Executive, to
either terminate the Executive's employment or eliminate his position. In order
to give effect to this purpose, the Executive shall receive certain payments and
benefits from the Company if there is a "Termination of Employment" during the
"Protection Period," as those terms are defined below, subject to the following
terms and conditions.

                  (b) The "Protection Period" shall be that period of time from
the date of this Agreement through and including December 31, 2003.

                  (c) "Termination of Employment" is defined to mean the
termination of the Executive's full-time employment with the Company for any
reason other than (i) the Executive's death, (ii) the Executive's "total
disability" (as defined in paragraph 2(e) below), (iii) the Executive's
voluntary termination of employment with the Company, (iv) the termination of
the Executive's employment by the Company for "good cause" (as defined in
paragraph 2(b) below), or (v) the termination of the Executive's employment by
the Company as a result of the Company's determination in its sole judgment that
the Executive has either (A) repeatedly failed to perform the duties and
assignments given to him or (B) consistently failed to perform the duties and
assignments given to him in a manner that is acceptable to the Company, based on
the level and quality of performance expected from an experienced executive at
the Executive's level in the Company.

                  (d) If there is a Termination of Employment during the
Protection Period, the Executive or his duly designated beneficiary will
continue to receive his gross bi-weekly salary in effect on the date of
Termination of Employment, subject to all required withholding taxes, in the
form of salary continuation ("Salary Continuation"), during the time period set
forth in Schedule I attached hereto (the "Salary Continuation Period").

                  (e) In addition to the Salary Continuation provided under
paragraph 1(d) above, during the Salary Continuation Period the Company shall
maintain in full force for the Executive's and his family's benefit, all life
insurance, health and accident insurance, and disability and medical
reimbursement plans in which the Executive and his family were entitled to
participate immediately prior to the date of Termination of Employment, under
the same terms as are made available during the Salary Continuation Period to
other executive employees of the Company from time to time, if the continued
participation of the Executive and his family in such



                                      - 2 -

<PAGE>   4



plans is possible under the general terms and provisions of such plans, programs
and arrangements. The costs of the Executive's and his family's continued
participation in such insurance and reimbursement plans shall be allocated
between the Company and the Executive in the same proportion as such costs were
allocated prior to the date of Termination of Employment. If the Executive's or
his family's continued participation is not possible, the Company shall
reimburse the Executive for his cost in obtaining comparable coverage, subject
to a maximum reimbursement during the Salary Continuation Period equal to 10% of
the Executive's base annual salary for the calendar year preceding the date of
Termination of Employment. For purposes of the Consolidated Omnibus Budget
Reconciliation Act ("COBRA"), the qualifying event that begins the Executive's
period of coverage shall be considered to occur on the last day for which health
coverage is provided during the Salary Continuation Period and for which the
Company contributes to the costs of such coverage pursuant to this paragraph
1(e).

                  (f) This paragraph 1 shall not be applicable to any
Termination of Employment following a "change in control" as defined in
paragraph 2(c) of this Agreement.

                  (g) The salary payments and benefits continuation provided for
in paragraphs 1(d) and 1(e) shall be in lieu of any other severance payments the
Executive might otherwise be entitled to from the Company whether in this
Agreement, under any employment agreement, or under a severance plan or policy
maintained by the Company for employees of Executive's rank and seniority.

                  (h) The Executive shall not be considered to be an employee of
the Company during the Salary Continuation Period for purposes of accruing any
benefits under the Company's 401(k) retirement plan, or any other retirement,
pension, profit sharing, savings or incentive or bonus plan maintained,
sponsored or administered by the Company ("Retirement or Bonus Plans") or under
the Company's vacation policy. During the Salary Continuation Period the
Executive shall not be entitled to any contribution by the Company on his behalf
or to his account under any Retirement or Bonus Plans nor shall he be entitled
to accrue any benefits under the Company's vacation policy.

         2.       CHANGE IN CONTROL PAYMENTS. 
                  --------------------------

                  (a) If during the Protection Period there is a "change in
control" and within two (2) years thereafter (i) the employment of the Executive
is terminated by the Company for other than "good cause" or the death or "total
disability" of the Executive or (ii) the Executive shall declare his employment
terminated for "good reason," then the Executive shall be entitled to the
following:




                                      - 3 -

<PAGE>   5



          A. All unpaid salary through the date of termination of employment
     plus credit for any vacation earned but not taken through the date of
     termination of employment (as permitted by the Company's policy on
     vacations) together with reimbursement for expenses not previously
     reimbursed through the date of termination, all of which will be paid
     immediately subject to all required withholding taxes.

          B. As a severance benefit, the Executive shall be entitled to an
     amount equal to his current base annual salary ("X") plus the annual
     average of all incentive compensation paid to the Executive by the Company
     during the three (3) calendar years preceding the date of termination or
     such portion of that period during which Executive was an employee ("Y"),
     multiplied by the number set forth in Schedule II attached hereto
     ("Severance Benefit"). The Severance Benefit will equal (X + Y) multiplied
     by the number set forth in Schedule II.

          C. This Severance Benefit, less all proper payroll deductions, shall
     be paid immediately to the Executive in a lump sum.

          D. In addition to the Severance Benefit, the Executive shall be
     entitled to continued participation for the number of months set forth in
     Schedule III attached hereto following the date of the termination of his
     employment, in all life insurance, health and accident insurance,
     disability and medical reimbursement plans, programs and arrangements in
     which the Executive and his family were entitled to participate immediately
     prior to the date of a "change in control," if the continued participation
     of the Executive and his family in such plans, programs and arrangements is
     possible under the general terms and provisions of such plans, programs and
     arrangements. The costs of the Executive's and his family's continued
     participation in such plans, programs and arrangements shall be allocated
     between the Company and the Executive in the same proportion as such costs
     were allocated prior to the date of the termination of his employment. If
     the Executive's or his family's continued participation is not possible,
     the Company shall reimburse the Executive at the end of each month during
     the period specified in Schedule III for his cost in obtaining comparable
     coverage, subject to a maximum reimbursement



                                      - 4 -

<PAGE>   6



     during each month equal to 2% of the Executive's base annual salary for the
     calendar year preceding the date of the termination of his employment. For
     purposes of COBRA, the qualifying event that begins the Executive's period
     of coverage shall be considered to occur on the last day for which health
     coverage is provided and for which the Company contributes to the costs of
     such coverage pursuant to this paragraph 2(a)D. The Company's obligations
     under this paragraph 2(a)D. with respect to life, health, accident and
     disability coverage shall be suspended with respect to any such coverage at
     any time that the Executive is eligible for comparable coverage from
     another employer.

                  The parties agree that the payments provided for in this
paragraph 2(a) shall be liquidated damages which are in lieu of any other
severance payments that the Executive would otherwise be entitled to under this
Agreement or under any severance plan or policy that would apply to him but for
this Agreement, and the Company agrees that the Executive shall not be required
to mitigate his damages by seeking other employment or otherwise.

                  (b) "Good cause" shall mean (i) the Executive's dishonesty,
fraud or breach of trust, or substantial misconduct in the performance of or
substantial nonperformance of his duties as an employee of the Company, (ii) any
act or omission by the Executive that results in a felony conviction or in a
regulatory body with jurisdiction over the Company removing the Executive from
office or requesting or recommending the suspension or removal of the Executive
or taking punitive action against the Executive, or (iii) a material breach by
the Executive of paragraphs 3 or 4 of this Agreement.

                  (c) For purposes of this Agreement, a "change in control"
shall have occurred if, after the date of this Agreement:

                           A. Any person (as such term is used in Section 13(d)
                  or Section 14(d)(2) of the Securities Exchange Act of 1934, as
                  amended, and the rules and regulations thereunder and
                  including any affiliate or associate of such person, as
                  defined in Rule 12b-2 under said Act, and any person acting in
                  concert with such person), directly or indirectly acquires or
                  becomes the beneficial owner of (within the meaning of Rule
                  13d-3 under said Act), or otherwise becomes entitled to vote,
                  stock of the Company or MGI or MNH (hereinafter referred to
                  individually as a "Merchants Company" and collectively as the

                  "Merchants Companies") with 25% or more of the voting power
                  entitled to be cast at elections for directors (excluding any
                  acquisition of stock in one Merchants Company by another
                  Merchants Company or the voting of stock in one Merchants
                  Company by another Merchants Company); or

                           B. There occurs any merger or consolidation of a
                  Merchants Company (excluding any merger or consolidation of
                  one Merchants Company with another) or any sale, lease or
                  exchange of all or any substantial part of the assets of any
                  of the Merchants Companies and their subsidiaries to any other
                  person, excluding any of the Merchants Companies, and (i) in
                  the case of a merger or consolidation, the holders of the
                  outstanding stock of any of the Merchants Companies entitled
                  to vote in elections of directors ("voting stock") immediately
                  before such merger or consolidation hold less than 50% of the
                  voting stock of the survivor of such merger or consolidation
                  or its parent; or (ii) in the case of any such sale, lease or
                  exchange, neither the Company nor either of the other
                  Merchants Companies or the Merchants Companies as a group owns
                  at least 50% of the voting stock of the other person; or

                           C. During any period of two (2) consecutive years,
                  individuals who at the beginning of such period constitute the
                  entire Board of Directors of any of the Merchants Companies
                  shall cease for any reason to constitute a majority thereof,
                  unless the election or the nomination for the election by that
                  company's shareholders or policyholders of each new Director
                  was approved by a vote of at least two-thirds of the Directors
                  then still in office who were Directors at the beginning of
                  the period.

                  (d) "Good reason" shall mean any of the following subsequent
to a "change in control" (i) the requirement that the Executive relocate his
principal place of business to a location that is more than 25 miles from the
Executive's principal place of business immediately prior to the date of a
"change in control," (ii) any assignment to the Executive without his express
written consent of any material duties, functions, authority or responsibilities
with respect to any of the Merchants Companies other than those duties,
functions, authority and responsibilities assigned to the Executive by the
Company prior to the "change in control," or any material limitation or
expansion without the Executive's express written consent of the material
duties, functions, authority and responsibilities assigned to the Executive by
the Company prior to the "change in



                                      - 6 -

<PAGE>   8



control," any such assignment, limitation or expansion being deemed a continuing
breach of this Agreement, (iii) a reduction in the Executive's then annual
salary paid by any of the Merchants Companies or (iv) failure by the Company to
obtain the assumption of, and the agreement to perform, this Agreement by any
successor or assign as contemplated in paragraph 8 hereof, and such relocation
described in the foregoing clause (i), such assignment, limitation or expansion
described in the foregoing clause (ii), reduction described in the foregoing
clause (iii) or failure described in the foregoing clause (iv) is not cured
within thirty (30) days after receipt by the Company of written notice from the
Executive describing such event, or (v) any removal of the Executive from, or
any failure to re-designate or re-elect the Executive to the position he held
immediately prior to the "change in control"; provided that in any event set
forth above in this subparagraph 2(d), the Executive shall have elected to
terminate his employment under this Agreement upon not less than sixty (60)
days' advance written notice to the Company, given, except in the case of a
continuing breach, within three calendar months after (A) failure to be so
elected or re-elected, or such removal, or (B) expiration of the thirty-day cure
period with respect to such event. An election by the Executive to terminate his
employment given under the provisions of this paragraph 2(d) shall not be deemed
a voluntary termination of employment by the Executive for the purpose of this
Agreement or any plan or practice of the Company.

                  (e) "Total disability," as used herein, shall mean total
disability as defined in any long-term disability plan sponsored by the Company
in which the Executive participates, or, if there is no such plan or it does not
define such term, then it shall mean the physical or mental incapacity of the
Executive which prevents him from substantially performing his duties as an
employee of the Company for a period of at least 180 days and the incapacity is
expected to be permanent and continues for the remainder of the Executive's
life.

                  (f) The payments provided for in this paragraph 2 are in lieu
of any payments provided for in any severance agreement, employment agreement or
similar agreement between the Executive and the Company which is dated prior to
the date of this Agreement ("Severance Agreement"). This Employee Retention
Agreement hereby voids, terminates and supersedes any such Severance Agreement
and the Executive hereby acknowledges that any such Severance Agreement is
hereby terminated and he no longer has any rights or benefits thereunder.

         3.       NON-DISCLOSURE OF CONFIDENTIAL INFORMATION.
                  -------------------------------------------

                  The Executive will not at any time use or disclose to any
third party any confidential information or trade secrets relating to the
business of any of the Merchants Companies, including business methods and
techniques, research data,



                                      - 7 -

<PAGE>   9



marketing and sales information, agent lists, underwriting and claims
procedures, investment strategies, reinsurance arrangements, agent compensation
plans, pricing data, and any other information concerning the business of any of
the Merchants Companies, their manner of operation, their plans, or other
information not disclosed to the general public or known in the insurance
industry, except for disclosure in the course of the Executive's duties
hereunder, or disclosure required by any law, rule, regulation or court order,
or disclosure which the Executive reasonably believes would subject him or any
of the Merchants Companies to liability if not made. This covenant will survive
the termination of this Agreement.

         4.       COVENANT NOT TO COMPETE. 
                  -----------------------

                  (a) The Executive shall not "compete," as that term is defined
in paragraph 4(c) below, with any of the Merchants Companies while employed by
the Company.

                  (b) If the Executive is receiving Salary Continuation payments
under paragraph 1(d) of this Agreement, he shall not compete with any of the
Merchants Companies during the first ninety (90) days of the Salary Continuation
Period, nor shall he "solicit," as that term is defined in paragraph 4(d) below,
any employee of the Company for a period of six (6) months after his last day of
employment with the Company, unless he shall have received prior written
approval from the Company.

                  (c) As used in this paragraph 4, the term "compete" means the
direct or indirect ownership, management, operation or control of, or
participation in the ownership, management, operation, or control of, or the
holding of the position of an officer, employee, partner, director, consultant
or similar positions, or the holding of any financial interest in, or the giving
of any aid or assistance to anyone else in the conduct of, any business that is
engaged in a property-casualty insurance business that offers substantially any
of the same lines of insurance and coverages offered, or proposed to be offered,
by any of the Merchants Companies at the time of the Executive's withdrawal from
or termination of employment with the Company, in any of the geographic markets
in which any of the Merchants Companies is then conducting business. Ownership
of stock of MGI or of one percent (1%) or less of the voting stock of any other
publicly held corporation shall not constitute a violation of this paragraph 4.

                  (d) As used in paragraph 4(b) above, the term "solicit" shall
mean the solicitation of any employee of the Company for the purpose of hiring
or engaging such employee to work for or otherwise assist any person who does or
intends to compete with any of the Merchants Companies.

                  (e) In addition to any other remedies that the Company may
have in law or in equity for a breach of the Executive's covenants set forth in
this paragraph 4, the Company may also cancel its obligations to pay to the
Executive any monies and other benefits otherwise due to the Executive under
this Agreement.

         5.       ENTIRE AGREEMENT.
                  ----------------

matter hereof.

requested, addressed to the addressee at the address set forth at the head of
this Agreement or such other address that such addressee has duly notified the

         7.       SEVERABILITY.
                  -------------

                  The invalidity or unenforceability of any particular provision
of this Agreement shall not affect the other provisions hereof, and this
Agreement shall be construed in all respects as if the invalid or unenforceable
provision had been omitted.

         8.       COMPANY ASSIGNMENT.
                  -------------------

                  The Company may not assign this Agreement, except that the
Company's obligations hereunder shall be binding legal obligations of any
successor to all or substantially all of the Company's business by purchase,
merger, consolidation, or otherwise. The Company shall require any successor or
assign (whether direct or indirect, by purchase, merger, consolidation or
otherwise) to all or substantially all of the business and/or assets of the
Company, by agreement in form and substance satisfactory to the Executive,
expressly, absolutely and unconditionally to assume and agree to perform this
Agreement in the same manner and to the same extent that the Company would be
required to perform it if no such succession or assignment had taken place. Any
failure of the Company to obtain such agreement prior to the effectiveness of
any such succession or assignment shall be a material breach of this Agreement.
As used in this Agreement, the term "Company" shall mean the Company as
hereinbefore defined and any successor or assign to its business and/or assets
as aforesaid which executes and delivers the agreement provided for in this
paragraph 8 or which otherwise



                                      - 9 -

becomes bound by all the terms and provisions of this Agreement
by operation of law.

         9.       NO ASSIGNMENT BY EXECUTIVE.
                  ---------------------------

                  No interest of the Executive or the Executive's spouse or any
other beneficiary under this Agreement, or any right to receive any payments or
distributions hereunder, shall be subject in any manner to sale, transfer,
assignment, pledge, attachment, garnishment, or other alienation or encumbrance
of any kind, nor may such interest or right to receive a payment or distribution
be taken, voluntarily or involuntarily, for the satisfaction of the obligations
or debts of, or other claims against, the Executive or the Executive's spouse or
other beneficiary, including claims for alimony, support, separate maintenance,
and claims in bankruptcy proceedings.

         10.      BENEFITS UNFUNDED.
                  ------------------

                  All rights of the Executive and the Executive's spouse or
other beneficiary under this Agreement shall at all times be entirely unfunded,
and no provision shall at any time be made with respect to segregating any
assets of the Company for payment of any amounts due hereunder. Neither the
Executive nor the Executive's spouse or other beneficiary shall have any
interest in or rights against any specific assets of the Company, and the
Executive and the Executive's spouse or other beneficiary shall have only the
rights of a general unsecured creditor of the Company.

         11.      WAIVER.
                  -------

                  No waiver by any party at any time of any breach by another
party of, or compliance with, any condition or provision of this Agreement to be
performed by the other party shall be deemed a waiver of any other provisions or
conditions at the same time or at any prior or subsequent time.

         12.      PAYMENTS IN EVENT OF DEATH.
                  ---------------------------

                  Upon the death of the Executive all amounts due and payable to
the Executive pursuant to paragraphs 1(d) and (e) and 2(a) of this Agreement
shall be paid to the person or persons designated by him as his beneficiary or
beneficiaries on the Form of Designation of Beneficiary attached hereto as
Exhibit A, or if no such person is designated then to his devisee, legatee or
other designee, or in their absence to his estate.

         13.      REDUCTION OF PARACHUTE PAYMENTS 
                  -------------------------------
                  AND EXCESSIVE EMPLOYEE REMUNERATION.
                  ------------------------------------

                  (a) In the event that a determination is made by legal counsel
for the Company that (i) the Executive would,



                                     - 10 -

<PAGE>   12



except for this paragraph 13, be subject to the excise tax provisions of Section
4999 of the Internal Revenue Code of 1986 (the "Code"), or any successor
sections thereof, as a result of a "parachute payment" (as defined in Section
280G(b)(2)(A) of the Code) made by the Company to the Executive pursuant to this
Agreement or any other agreement, plan or arrangement, or (2) a federal income
tax deduction would not be allowed to the Company for all or a part of such
payments by reason of Section 280G(a) of the Code (or any successor provision),
the payments to which the Executive would otherwise be entitled hereunder shall
be reduced, eliminated, or postponed in such amounts as are required to reduce
the aggregate "present value" (as defined in Section 280G(d)(4) of the Code) of
such payments to one dollar less than an amount equal to three times the
Executive's "base amount" (as defined in Sections 280G(b)(3)(A) and 280G(d)(1)
and (2) of the Code), to the end that the Executive is not subject to tax
pursuant to such Section 4999 and no deduction is disallowed by reason of such
Section 280G(a). To achieve such reduction in aggregate present value, the
Executive shall determine which item or items payable hereunder shall be
reduced, eliminated, or postponed, the amount of each such reduction,
elimination, or postponement, and the period of each postponement. The Company
shall direct its legal counsel to review the payments made to the Executive and
shall provide to the Executive such information as is reasonably necessary for
the Executive to make the determinations contemplated in this paragraph.

                  (b) In the event that a determination is made by legal counsel
for the Company that the Company would not be allowed to deduct remuneration
payable to the Executive as a result of the limits imposed by Section 162(m) of
the Code, or any successor sections thereof, the payments to which the Executive
would otherwise be entitled hereunder shall be reduced, eliminated, or postponed
in such amounts as are required to avoid the limits imposed by Section 162(m).
The procedures set forth in paragraph 13(a) to accomplish such reduction,
elimination or postponement shall apply to this paragraph 13(b).

         14.      APPLICABLE LAW.
                  ---------------

                  This Agreement shall be construed and interpreted in
accordance with the internal substantive laws of the State of New York without
taking into account its laws on the conflict of law.

         15.      ARBITRATION.
                  ------------

                  The Company and the Executive shall attempt to resolve between
them any dispute which arises hereunder. If they cannot agree within ten (10)
days after either party submits a demand for arbitration to the other party,
then the issue shall be submitted to arbitration with each party having the
right to appoint one (1) arbitrator and those two (2) arbitrators mutually



                                     - 11 -

<PAGE>   13



selecting a third arbitrator. The rules of the American Arbitration Association
for the arbitration of commercial disputes shall apply and the decision of 2 of
the 3 arbitrators shall be final. The arbitrators must reach a decision within
ninety (90) days after the selection of the third arbitrator. The arbitration
shall take place in Buffalo, New York. The arbitrators shall apply New York law.

         16.      AMENDMENT.
                  ----------

                  This Agreement shall be amended only by a written document
signed by each party hereto.

         17.      GENDER.
                  -------

                  The use of the masculine gender when used to refer to the
Executive in this Agreement or in any Exhibit or Schedule hereto shall be deemed
to be the female gender if the Executive is a female.

         18.      EMPLOYEE-AT-WILL.
                  -----------------

                  Notwithstanding any provision in this Agreement, the Executive
will remain an at-will employee of the Company, whose employment may be
terminated by the Company at any time subject to the Executive's rights to
receive the benefits specifically provided in paragraphs 1 and 2 in this
Agreement, as applicable.

                  IN WITNESS WHEREOF, the parties have executed this Agreement
effective as of the day and year first above written.


                                             THE EXECUTIVE:

                              DATED: MARCH 1, 1999

                          EMPLOYEE RETENTION AGREEMENT
                          ----------------------------

     This AGREEMENT ("Agreement"), dated as of March 1, 1999, is by and between
KENNETH J. WILSON, residing at 15 Snyderwoods Court, Snyder, New York 14226 (the
"Executive") and MERCHANTS MUTUAL INSURANCE COMPANY, a New York mutual insurance
company with its principal office at 250 Main Street, Buffalo, New York 14202
(the "Company").

                                    RECITALS:

     WHEREAS, the Company is responsible for managing the business of Merchants
Group, Inc. ("MGI") and MGI's wholly-owned subsidiary, Merchants Insurance
Company of New Hampshire, Inc. ("MNH"), under a Management Agreement dated
September 29, 1986 by and among the Company, MGI and MNH (the "Management
Agreement"); and

     WHEREAS, MGI has given notice to the Company that it will terminate the
Management Agreement no later than at the end of the required five-year notice
period; and

     WHEREAS, the Executive is a key employee of the Company; and

     WHEREAS, the Company believes that the Executive's continued employment
with the Company will enhance the Company's ability to continue to manage the
business of the Company, MGI and MNH throughout the period prior to the
effective date of the termination of the Management Agreement; and

     WHEREAS, the Company believes that the Executive's continued employment
with the Company will be in the collective best interests of the Company, MGI
and MNH; and

     WHEREAS, the Company believes that by extending certain financial
incentives to the Executive it will assist the Company in retaining the services
of the Executive throughout the period prior to the effective date of the
termination of the Management Agreement; and

     WHEREAS, the Executive and the Company desire to enter into this Agreement
in order to provide for such financial incentives.

     NOW, THEREFORE, in consideration of the promises and the mutual agreements
herein contained, the adequacy and sufficiency of which are hereby acknowledged,
the Company and the Executive agree as follows:


<PAGE>   3



      1. SALARY CONTINUATION AND BENEFITS.

         (a) The purpose of this paragraph 1 is to provide the Executive with a
continuation of salary and certain benefits in the event it is necessary or
advisable for the Company, through no fault of the Executive, to either
terminate the Executive's employment or eliminate his position. In order to give
effect to this purpose, the Executive shall receive certain payments and
benefits from the Company if there is a "Termination of Employment" during the
"Protection Period," as those terms are defined below, subject to the following
terms and conditions.

         (b) The "Protection Period" shall be that period of time from the date
of this Agreement through and including December 31, 2003.

         (c) "Termination of Employment" is defined to mean the termination of
the Executive's full-time employment with the Company for any reason other than
(i) the Executive's death, (ii) the Executive's "total disability" (as defined
in paragraph 2(e) below), (iii) the Executive's voluntary termination of
employment with the Company, (iv) the termination of the Executive's employment
by the Company for "good cause" (as defined in paragraph 2(b) below), or (v) the
termination of the Executive's employment by the Company as a result of the
Company's determination in its sole judgment that the Executive has either (A)
repeatedly failed to perform the duties and assignments given to him or (B)
consistently failed to perform the duties and assignments given to him in a
manner that is acceptable to the Company, based on the level and quality of
performance expected from an experienced executive at the Executive's level in
the Company.

         (d) If there is a Termination of Employment during the Protection
Period, the Executive or his duly designated beneficiary will continue to
receive his gross bi-weekly salary in effect on the date of Termination of
Employment, subject to all required withholding taxes, in the form of salary
continuation ("Salary Continuation"), during the time period set forth in
Schedule I attached hereto (the "Salary Continuation Period").

         (e) In addition to the Salary Continuation provided under paragraph
1(d) above, during the Salary Continuation Period the Company shall maintain in
full force for the Executive's and his family's benefit, all life insurance,
health and accident insurance, and disability and medical reimbursement plans in
which the Executive and his family were entitled to participate immediately
prior to the date of Termination of Employment, under the same terms as are made
available during the Salary Continuation Period to other executive employees of
the Company from time to time, if the continued participation of the Executive
and his family in such

                                      - 2 -


<PAGE>   4



plans is possible under the general terms and provisions of such plans, programs
and arrangements. The costs of the Executive's and his family's continued
participation in such insurance and reimbursement plans shall be allocated
between the Company and the Executive in the same proportion as such costs were
allocated prior to the date of Termination of Employment. If the Executive's or
his family's continued participation is not possible, the Company shall
reimburse the Executive for his cost in obtaining comparable coverage, subject
to a maximum reimbursement during the Salary Continuation Period equal to 10% of
the Executive's base annual salary for the calendar year preceding the date of
Termination of Employment. For purposes of the Consolidated Omnibus Budget
Reconciliation Act ("COBRA"), the qualifying event that begins the Executive's
period of coverage shall be considered to occur on the last day for which health
coverage is provided during the Salary Continuation Period and for which the
Company contributes to the costs of such coverage pursuant to this paragraph
1(e).

         (f) This paragraph 1 shall not be applicable to any Termination of
Employment following a "change in control" as defined in paragraph 2(c) of this
Agreement.

         (g) The salary payments and benefits continuation provided for in
paragraphs 1(d) and 1(e) shall be in lieu of any other severance payments the
Executive might otherwise be entitled to from the Company whether in this
Agreement, under any employment agreement, or under a severance plan or policy
maintained by the Company for employees of Executive's rank and seniority.

         (h) The Executive shall not be considered to be an employee of the
Company during the Salary Continuation Period for purposes of accruing any
benefits under the Company's 401(k) retirement plan, or any other retirement,
pension, profit sharing, savings or incentive or bonus plan maintained,
sponsored or administered by the Company ("Retirement or Bonus Plans") or under
the Company's vacation policy. During the Salary Continuation Period the
Executive shall not be entitled to any contribution by the Company on his behalf
or to his account under any Retirement or Bonus Plans nor shall he be entitled
to accrue any benefits under the Company's vacation policy.

      2. CHANGE IN CONTROL PAYMENTS.

         (a) If during the Protection Period there is a "change in control" and
within two (2) years thereafter (i) the employment of the Executive is
terminated by the Company for other than "good cause" or the death or "total
disability" of the Executive or (ii) the Executive shall declare his employment
terminated for "good reason," then the Executive shall be entitled to the
following:

                                      - 3 -


<PAGE>   5



            A. All unpaid salary through the date of termination of employment
      plus credit for any vacation earned but not taken through the date of
      termination of employment (as permitted by the Company's policy on
      vacations) together with reimbursement for expenses not previously
      reimbursed through the date of termination, all of which will be paid
      immediately subject to all required withholding taxes.

            B. As a severance benefit, the Executive shall be entitled to an
      amount equal to his current base annual salary ("X") plus the annual
      average of all incentive compensation paid to the Executive by the Company
      during the three (3) calendar years preceding the date of termination or
      such portion of that period during which Executive was an employee ("Y"),
      multiplied by the number set forth in Schedule II attached hereto
      ("Severance Benefit"). The Severance Benefit will equal (X + Y) multiplied
      by the number set forth in Schedule II.

            C. This Severance Benefit, less all proper payroll deductions, shall
      be paid immediately to the Executive in a lump sum.

            D. In addition to the Severance Benefit, the Executive shall be
      entitled to continued participation for the number of months set forth in
      Schedule III attached hereto following the date of the termination of his
      employment, in all life insurance, health and accident insurance,
      disability and medical reimbursement plans, programs and arrangements in
      which the Executive and his family were entitled to participate
      immediately prior to the date of a "change in control," if the continued
      participation of the Executive and his family in such plans, programs and
      arrangements is possible under the general terms and provisions of such
      plans, programs and arrangements. The costs of the Executive's and his
      family's continued participation in such plans, programs and arrangements
      shall be allocated between the Company and the Executive in the same
      proportion as such costs were allocated prior to the date of the
      termination of his employment. If the Executive's or his family's
      continued participation is not possible, the Company shall reimburse the
      Executive at the end of each month during the period specified in Schedule
      III for his cost in obtaining comparable coverage, subject to a maximum
      reimbursement

                                      - 4 -


<PAGE>   6



            during each month equal to 2% of the Executive's base annual salary
            for the calendar year preceding the date of the termination of his
            employment. For purposes of COBRA, the qualifying event that begins
            the Executive's period of coverage shall be considered to occur on
            the last day for which health coverage is provided and for which the
            Company contributes to the costs of such coverage pursuant to this
            paragraph 2(a)D. The Company's obligations under this paragraph
            2(a)D. with respect to life, health, accident and disability
            coverage shall be suspended with respect to any such coverage at any
            time that the Executive is eligible for comparable coverage from
            another employer.

               The parties agree that the payments provided for in this 
paragraph 2(a) shall be liquidated damages which are in lieu of any other
severance payments that the Executive would otherwise be entitled to under this
Agreement or under any severance plan or policy that would apply to him but for
this Agreement, and the Company agrees that the Executive shall not be required
to mitigate his damages by seeking other employment or otherwise.

            (b) "Good cause" shall mean (i) the Executive's dishonesty, fraud or
breach of trust, or substantial misconduct in the performance of or substantial
nonperformance of his duties as an employee of the Company, (ii) any act or
omission by the Executive that results in a felony conviction or in a regulatory
body with jurisdiction over the Company removing the Executive from office or
requesting or recommending the suspension or removal of the Executive or taking
punitive action against the Executive, or (iii) a material breach by the
Executive of paragraphs 3 or 4 of this Agreement.

            (c) For purposes of this Agreement, a "change in control" shall have
occurred if, after the date of this Agreement:

                A. Any person (as such term is used in Section 13(d) or
            Section 14(d)(2) of the Securities Exchange Act of 1934, as amended,
            and the rules and regulations thereunder and including any affiliate
            or associate of such person, as defined in Rule 12b-2 under said
            Act, and any person acting in concert with such person), directly or
            indirectly acquires or becomes the beneficial owner of (within the
            meaning of Rule 13d-3 under said Act), or otherwise becomes entitled
            to vote, stock of the Company or MGI or MNH (hereinafter referred to
            individually as a "Merchants Company" and collectively as the

                                      - 5 -

            "Merchants Companies") with 25% or more of the voting power entitled
            to be cast at elections for directors (excluding any acquisition of
            stock in one Merchants Company by another Merchants Company or the
            voting of stock in one Merchants Company by another Merchants
            Company); or

                  B. There occurs any merger or consolidation of a Merchants
            Company (excluding any merger or consolidation of one Merchants
            Company with another) or any sale, lease or exchange of all or any
            substantial part of the assets of any of the Merchants Companies and
            their subsidiaries to any other person, excluding any of the
            Merchants Companies, and (i) in the case of a merger or
            consolidation, the holders of the outstanding stock of any of the
            Merchants Companies entitled to vote in elections of directors
            ("voting stock") immediately before such merger or consolidation
            hold less than 50% of the voting stock of the survivor of such
            merger or consolidation or its parent; or (ii) in the case of any
            such sale, lease or exchange, neither the Company nor either of the
            other Merchants Companies or the Merchants Companies as a group owns
            at least 50% of the voting stock of the other person; or

                  C. During any period of two (2) consecutive years, individuals
            who at the beginning of such period constitute the entire Board of
            Directors of any of the Merchants Companies shall cease for any
            reason to constitute a majority thereof, unless the election or the
            nomination for the election by that company's shareholders or
            policyholders of each new Director was approved by a vote of at
            least two-thirds of the Directors then still in office who were
            Directors at the beginning of the period.

           (d) "Good reason" shall mean any of the following subsequent to a
"change in control" (i) the requirement that the Executive relocate his
principal place of business to a location that is more than 25 miles from the
Executive's principal place of business immediately prior to the date of a
"change in control," (ii) any assignment to the Executive without his express
written consent of any material duties, functions, authority or responsibilities
with respect to any of the Merchants Companies other than those duties,
functions, authority and responsibilities assigned to the Executive by the
Company prior to the "change in control," or any material limitation or
expansion without the Executive's express written consent of the material
duties, functions, authority and responsibilities assigned to the Executive by
the Company prior to the "change in

                                      - 6 -

control," any such assignment, limitation or expansion being deemed a continuing
breach of this Agreement, (iii) a reduction in the Executive's then annual
salary paid by any of the Merchants Companies or (iv) failure by the Company to
obtain the assumption of, and the agreement to perform, this Agreement by any
successor or assign as contemplated in paragraph 8 hereof, and such relocation
described in the foregoing clause (i), such assignment, limitation or expansion
described in the foregoing clause (ii), reduction described in the foregoing
clause (iii) or failure described in the foregoing clause (iv) is not cured
within thirty (30) days after receipt by the Company of written notice from the
Executive describing such event, or (v) any removal of the Executive from, or
any failure to re-designate or re-elect the Executive to the position he held
immediately prior to the "change in control"; provided that in any event set
forth above in this subparagraph 2(d), the Executive shall have elected to
terminate his employment under this Agreement upon not less than sixty (60)
days' advance written notice to the Company, given, except in the case of a
continuing breach, within three calendar months after (A) failure to be so
elected or re-elected, or such removal, or (B) expiration of the thirty-day cure
period with respect to such event. An election by the Executive to terminate his
employment given under the provisions of this paragraph 2(d) shall not be deemed
a voluntary termination of employment by the Executive for the purpose of this
Agreement or any plan or practice of the Company.

         (e) "Total disability," as used herein, shall mean total disability as
defined in any long-term disability plan sponsored by the Company in which the
Executive participates, or, if there is no such plan or it does not define such
term, then it shall mean the physical or mental incapacity of the Executive
which prevents him from substantially performing his duties as an employee of
the Company for a period of at least 180 days and the incapacity is expected to
be permanent and continues for the remainder of the Executive's life.

         (f) The payments provided for in this paragraph 2 are in lieu of any
payments provided for in any severance agreement, employment agreement or
similar agreement between the Executive and the Company which is dated prior to
the date of this Agreement ("Severance Agreement"). This Employee Retention
Agreement hereby voids, terminates and supersedes any such Severance Agreement
and the Executive hereby acknowledges that any such Severance Agreement is
hereby terminated and he no longer has any rights or benefits thereunder.

     3.  NON-DISCLOSURE OF CONFIDENTIAL INFORMATION.

         The Executive will not at any time use or disclose to any third party
any confidential information or trade secrets relating to the business of any of
the Merchants Companies, including business methods and techniques, research
data,

                                      - 7 -


<PAGE>   9



marketing and sales information, agent lists, underwriting and claims
procedures, investment strategies, reinsurance arrangements, agent compensation
plans, pricing data, and any other information concerning the business of any of
the Merchants Companies, their manner of operation, their plans, or other
information not disclosed to the general public or known in the insurance
industry, except for disclosure in the course of the Executive's duties
hereunder, or disclosure required by any law, rule, regulation or court order,
or disclosure which the Executive reasonably believes would subject him or any
of the Merchants Companies to liability if not made. This covenant will survive
the termination of this Agreement.

      4. COVENANT NOT TO COMPETE.

         (a) The Executive shall not "compete," as that term is defined in
paragraph 4(c) below, with any of the Merchants Companies while employed by the
Company.

         (b) If the Executive is receiving Salary Continuation payments under
paragraph 1(d) of this Agreement, he shall not compete with any of the Merchants
Companies during the first ninety (90) days of the Salary Continuation Period,
nor shall he "solicit," as that term is defined in paragraph 4(d) below, any
employee of the Company for a period of six (6) months after his last day of
employment with the Company, unless he shall have received prior written
approval from the Company.

         (c) As used in this paragraph 4, the term "compete" means the direct or
indirect ownership, management, operation or control of, or participation in the
ownership, management, operation, or control of, or the holding of the position
of an officer, employee, partner, director, consultant or similar positions, or
the holding of any financial interest in, or the giving of any aid or assistance
to anyone else in the conduct of, any business that is engaged in a
property-casualty insurance business that offers substantially any of the same
lines of insurance and coverages offered, or proposed to be offered, by any of
the Merchants Companies at the time of the Executive's withdrawal from or
termination of employment with the Company, in any of the geographic markets in
which any of the Merchants Companies is then conducting business. Ownership of
stock of MGI or of one percent (1%) or less of the voting stock of any other
publicly held corporation shall not constitute a violation of this paragraph 4.

         (d) As used in paragraph 4(b) above, the term "solicit" shall mean the
solicitation of any employee of the Company for the purpose of hiring or
engaging such employee to work for or otherwise assist any person who does or
intends to compete with any of the Merchants Companies.

                                      - 8 -


<PAGE>   10



         (e) In addition to any other remedies that the Company may have in law
or in equity for a breach of the Executive's covenants set forth in this
paragraph 4, the Company may also cancel its obligations to pay to the Executive
any monies and other benefits otherwise due to the Executive under this
Agreement.

      5. ENTIRE AGREEMENT.

         The terms and provisions of this Agreement constitute the entire
agreement between the parties and supersede any previous oral or written
communications, representations, or agreements with respect to the subject
matter hereof.

      6. NOTICE.

         Any notices given hereunder shall be in writing and shall be given by
personal delivery or by certified or registered mail, return receipt requested,
addressed to the addressee at the address set forth at the head of this
Agreement or such other address that such addressee has duly notified the other
party to forward notices to hereunder.

      7. SEVERABILITY.

         The invalidity or unenforceability of any particular provision of this
Agreement shall not affect the other provisions hereof, and this Agreement shall
be construed in all respects as if the invalid or unenforceable provision had
been omitted.

      8. COMPANY ASSIGNMENT.

         The Company may not assign this Agreement, except that the Company's
obligations hereunder shall be binding legal obligations of any successor to all
or substantially all of the Company's business by purchase, merger,
consolidation, or otherwise. The Company shall require any successor or assign
(whether direct or indirect, by purchase, merger, consolidation or otherwise) to
all or substantially all of the business and/or assets of the Company, by
agreement in form and substance satisfactory to the Executive, expressly,
absolutely and unconditionally to assume and agree to perform this Agreement in
the same manner and to the same extent that the Company would be required to
perform it if no such succession or assignment had taken place. Any failure of
the Company to obtain such agreement prior to the effectiveness of any such
succession or assignment shall be a material breach of this Agreement. As used
in this Agreement, the term "Company" shall mean the Company as hereinbefore
defined and any successor or assign to its business and/or assets as aforesaid
which executes and delivers the agreement provided for in this paragraph 8 or
which otherwise

                                      - 9 -


<PAGE>   11



becomes bound by all the terms and provisions of this Agreement by operation of
law.

      9. NO ASSIGNMENT BY EXECUTIVE.

         No interest of the Executive or the Executive's spouse or any other
beneficiary under this Agreement, or any right to receive any payments or
distributions hereunder, shall be subject in any manner to sale, transfer,
assignment, pledge, attachment, garnishment, or other alienation or encumbrance
of any kind, nor may such interest or right to receive a payment or distribution
be taken, voluntarily or involuntarily, for the satisfaction of the obligations
or debts of, or other claims against, the Executive or the Executive's spouse or
other beneficiary, including claims for alimony, support, separate maintenance,
and claims in bankruptcy proceedings.

     10. BENEFITS UNFUNDED.

         All rights of the Executive and the Executive's spouse or other
beneficiary under this Agreement shall at all times be entirely unfunded, and no
provision shall at any time be made with respect to segregating any assets of
the Company for payment of any amounts due hereunder. Neither the Executive nor
the Executive's spouse or other beneficiary shall have any interest in or rights
against any specific assets of the Company, and the Executive and the
Executive's spouse or other beneficiary shall have only the rights of a general
unsecured creditor of the Company.

     11. WAIVER.

         No waiver by any party at any time of any breach by another party of,
or compliance with, any condition or provision of this Agreement to be performed
by the other party shall be deemed a waiver of any other provisions or
conditions at the same time or at any prior or subsequent time.

     12. PAYMENTS IN EVENT OF DEATH.

         Upon the death of the Executive all amounts due and payable to the
Executive pursuant to paragraphs 1(d) and (e) and 2(a) of this Agreement shall
be paid to the person or persons designated by him as his beneficiary or
beneficiaries on the Form of Designation of Beneficiary attached hereto as
Exhibit A, or if no such person is designated then to his devisee, legatee or
other designee, or in their absence to his estate.

     13. REDUCTION OF PARACHUTE PAYMENTS AND EXCESSIVE EMPLOYEE REMUNERATION.

         (a) In the event that a determination is made by legal counsel for the
Company that (i) the Executive would,

                                     - 10 -


<PAGE>   12



except for this paragraph 13, be subject to the excise tax provisions of Section
4999 of the Internal Revenue Code of 1986 (the "Code"), or any successor
sections thereof, as a result of a "parachute payment" (as defined in Section
280G(b)(2)(A) of the Code) made by the Company to the Executive pursuant to this
Agreement or any other agreement, plan or arrangement, or (2) a federal income
tax deduction would not be allowed to the Company for all or a part of such
payments by reason of Section 280G(a) of the Code (or any successor provision),
the payments to which the Executive would otherwise be entitled hereunder shall
be reduced, eliminated, or postponed in such amounts as are required to reduce
the aggregate "present value" (as defined in Section 280G(d)(4) of the Code) of
such payments to one dollar less than an amount equal to three times the
Executive's "base amount" (as defined in Sections 280G(b)(3)(A) and 280G(d)(1)
and (2) of the Code), to the end that the Executive is not subject to tax
pursuant to such Section 4999 and no deduction is disallowed by reason of such
Section 280G(a). To achieve such reduction in aggregate present value, the
Executive shall determine which item or items payable hereunder shall be
reduced, eliminated, or postponed, the amount of each such reduction,
elimination, or postponement, and the period of each postponement. The Company
shall direct its legal counsel to review the payments made to the Executive and
shall provide to the Executive such information as is reasonably necessary for
the Executive to make the determinations contemplated in this paragraph.

         (b) In the event that a determination is made by legal counsel for the
Company that the Company would not be allowed to deduct remuneration payable to
the Executive as a result of the limits imposed by Section 162(m) of the Code,
or any successor sections thereof, the payments to which the Executive would
otherwise be entitled hereunder shall be reduced, eliminated, or postponed in
such amounts as are required to avoid the limits imposed by Section 162(m). The
procedures set forth in paragraph 13(a) to accomplish such reduction,
elimination or postponement shall apply to this paragraph 13(b).

     14. APPLICABLE LAW.

         This Agreement shall be construed and interpreted in accordance with
the internal substantive laws of the State of New York without taking into
account its laws on the conflict of law.

     15. ARBITRATION.

         The Company and the Executive shall attempt to resolve between them any
dispute which arises hereunder. If they cannot agree within ten (10) days after
either party submits a demand for arbitration to the other party, then the issue
shall be submitted to arbitration with each party having the right to appoint
one (1) arbitrator and those two (2) arbitrators mutually

                                     - 11 -


<PAGE>   13



selecting a third arbitrator. The rules of the American Arbitration Association
for the arbitration of commercial disputes shall apply and the decision of 2 of
the 3 arbitrators shall be final. The arbitrators must reach a decision within
ninety (90) days after the selection of the third arbitrator. The arbitration
shall take place in Buffalo, New York. The arbitrators shall apply New York law.

     16. AMENDMENT.

         This Agreement shall be amended only by a written document signed by
each party hereto.

     17. GENDER.

         The use of the masculine gender when used to refer to the Executive in
this Agreement or in any Exhibit or Schedule hereto shall be deemed to be the
female gender if the Executive is a female.

     18. EMPLOYEE-AT-WILL.

         Notwithstanding any provision in this Agreement, the Executive will
remain an at-will employee of the Company, whose employment may be terminated by
the Company at any time subject to the Executive's rights to receive the
benefits specifically provided in paragraphs 1 and 2 in this Agreement, as
applicable.

         IN WITNESS WHEREOF, the parties have executed this Agreement effective
as of the day and year first above written.

                                   THE EXECUTIVE:
