Item 1.   BUSINESS

GENERAL

      As used in this Annual Report on Form 10-K, (i) "Philadelphia Insurance"
refers to Philadelphia Consolidated Holding Corp., (ii) the "Company" refers to
Philadelphia Insurance and its subsidiaries, doing business as Philadelphia
Insurance Companies; (iii) the "Insurance Subsidiaries" refers to Philadelphia
Indemnity Insurance Company ("PIIC") and Philadelphia Insurance Company ("PIC"),
collectively; and (iv) "MIA" refers to Maguire Insurance Agency, Inc., a captive
underwriting manager. Philadelphia Insurance was incorporated in Pennsylvania in
1984, to serve as a holding company for its three wholly owned subsidiaries
(PIIC, PIC, MIA).

      1997 represented the fourth consecutive year since its 1993 initial public
offering that the Company has reported growth in gross written premiums and net
income while experiencing a combined ratio substantially lower than the
commercial property and casualty insurance industry as a whole. The Company's
four year compound annual growth rate for gross written premiums, and net income
was 29.2% and 41.3%, respectively, while the four year weighted average combined
ratio (GAAP basis) was 86.8%. The combined ratio is the sum of the net loss and
loss adjustment expenses and acquisition costs and other underwriting expenses
divided by net earned premiums. The Company believes its profitable growth is
attributable to adhering to conservative underwriting guidelines and pricing
discipline while supplementing historically profitable product lines with growth
in certain excess liability products, commercial multi-peril products, and
selected professional liability coverages.

      The Insurance Subsidiaries have been assigned an "A" (Excellent) Best's
Rating by A.M. Best Company. According to A.M. Best, the "A" (Excellent) rating
is issued to companies that demonstrate excellent financial strength and ability
to meet its obligations to policyholders. A.M. Best ratings are based upon
factors relevant to policyholders and are not directed toward the protection of
investors. The Insurance Subsidiaries also possess an "A" claims paying ability
rating by Standard & Poor's. According to Standard & Poor's, insurers rated "A"
offer good financial security for policyholders. The Company believes that the
"A" ratings assigned by A.M. Best and Standard & Poor's are important factors in
marketing its products.


BUSINESS STRATEGY

      The Company designs property and casualty insurance products incorporating
value-added coverages and services for select target industries or niches. A
mixed marketing strategy is utilized, wherein, the Company's production
underwriting organization markets the Company's insurance products directly to
the insured or through the Company's 35 preferred agents, or also accepts
business from independent insurance brokers. The Company's production
underwriting organization, consisting of 100 professionals at year 1997,
operates from 38 proprietary field offices located across the United States and
includes telemarketing staffs at its regional offices and the Philadelphia Home
Office. Approximately, 53% of the total 1997 gross premium was produced
indirectly either through the Company's 35 preferred agents (11%) or its some
4,000 broker relationships (42%).

      Commercial Automobile and Excess Liability: The Company has provided
Commercial Automobile Products to the leasing and rent-a-car industries for 35
years. Products offered to the rent-a-car industry include coverage for the
business owner's property, dual interest liability, and physical damage on the
rental vehicle.

      Additionally, through arrangements with a number of the largest rent-a-car
companies, the Company also offers its excess liability product at the rental
car counter to rent-a-car customers protecting them against liability for bodily
injury and property damage, which is excess of the statutory coverage provided
with the rental vehicle and primary over the renter's personal automobile
insurance coverage.

      In keeping with its marketing philosophy, the Company includes a number of
special features in its rental car products and services in an attempt to
differentiate them from the competition. Such features include: catastrophic
comprehensive coverage for losses due to fire, lightening, windstorm, hail,
flood, earthquake and other specified causes; subrogation services on
self-insured physical damage; liability deductibles; and self-insured retention
programs.

      The Company also offers a full range of liability and physical damage
coverages to automobile leasing companies and their customers. For the driver
(the lessee), coverages include both primary liability and physical damage
coverage on the vehicle. For the owner (the lessor), coverages include
contingent and excess liability over the primary liability layer which protects
lessors in the event of a loss when the primary coverage is absent or inadequate
and contingent physical damage coverage. Additional products offered to leasing
companies include interim primary liability and physical damage coverage, which
protects the lessor of the vehicle before and after it is delivered to the
lessee; residual value coverage which guarantees the value of the leased vehicle
at the termination of the lease; and guaranteed asset protection coverage which
protects the lessor and lessee for the difference between the leased vehicle's
actual cash value and the lease or loan net value in instances where the vehicle
is stolen or damaged beyond repair.

      Commercial Package: The Company has been providing Commercial Multi Peril
Package Policies ("Package Programs") to specific targeted niche markets for
over 10 years. Among the organizations to which the Company offers its specialty
niche package programs are non-profit social service agencies, introduced in
1988, health and fitness organizations, assisted living facilities, nursing
homes, private and specialty training schools, and condominium / homeowner
association facilities. The package policies provide a combination of
comprehensive


                                       3
<PAGE>   4
liability, property and automobile coverages with limits up to $1.0 million and
umbrella limits on an optional basis up to $5.0 million. The package policies
are further tailored to include special value-added features addressing the
unique aspects of each of the above niche markets differentiating the Company's
product offerings from those of its competitors.

      Specialty Lines: The Company has been providing specialty professional
liability products for approximately ten years, initially offering Directors &
Officers Liability coverage to Nonprofit 501(c)(3) tax exempt organizations. The
Company's recent efforts have been focused on broadening the target market for
its specialty lines product offerings through the expansion of its field
production underwriting staff along with introducing new product offerings. The
Company has significantly expanded its errors and omissions product offered to
the independent insurance agent along with its miscellaneous professional
liability program which is currently offered to an array of professionals
including: mortgage bankers, claims adjusters, lawyers, title abstractors, and
financial advisors. During 1996, the Company introduced a proprietary package of
coverages in its Executive Safeguard policy offered to public and private
companies. The coverages offered in the Executive Safeguard policy include:
directors and officers liability, employment practices liability, fiduciary
liability, and kidnap ransom insurance.

      The following table provides the geographic distribution of the Company's
risks insured as represented by direct earned premiums for all product lines for
the year ended December 31, 1997. No other state accounted for more than 2% of
total direct earned premiums for all product lines for the year ended December
31, 1997.

UNDERWRITING AND PRICING

      The Company's underwriting function is segregated into three independent
groups: Commercial Lines, Specialty Lines, and Regional Underwriting. Commercial
and Specialty Lines responsibilities include: pricing all business, managing the
risk selection process, and monitoring loss ratios by product and insured. The
Regional Underwriting group primarily performs preliminary underwriting and
processing functions along with providing customer service.

      The Commercial Lines group, which has underwriting responsibility for the
Company's commercial automobile and commercial package products, currently
consists of home office underwriters that are supported by underwriting
assistants, raters, and other policy administration personnel. The Commercial
Lines underwriters and support staff are organized into geographic underwriting
teams responsible for underwriting and servicing specific commercial automobile
and commercial package products. Each underwriting team is under the direction
of a Senior Underwriter who reports to the Vice President of Commercial Lines
Underwriting.


                                       4
<PAGE>   5
      The Specialty Lines group, which has underwriting responsibility for the
Company's professional liability products, consists of home office underwriters
who report to the Vice President of Specialty Lines Underwriting, and are
supported by underwriting assistants. The Specialty Lines underwriters have
responsibility for underwriting specific professional liability products within
designated Company marketing regions.

      During 1997, the Company established a pilot commercial lines underwriting
function in its Southeast regional marketing office to strengthen local market
intelligence, further develop relationships with agents and insureds and enhance
overall customer service. This pilot underwriting function operates under
well-defined underwriting and pricing guidelines developed by the home office
Commercial Lines Underwriting department and has quoting and binding authority
on all risks falling within these guidelines. Risks not falling within the
guidelines are referred to the home office for underwriting decisions.

      As a result of the success of this pilot office, the Company plans to
establish commercial lines underwriting functions in its Western and Northeast
regional marketing offices during 1998 under the currently established
structure. In addition, the Specialty Lines division has also identified key
regional offices in which Specialty Lines underwriters will be placed. During
the fourth quarter of 1997, a pilot Specialty Lines Underwriting unit was
established in the Company's Western region. The Specialty Lines underwriters
will also operate under a matrix organization structure similar to that of
Commercial Lines underwriting where final underwriting decisions falling outside
of established guidelines will be referred to the home office. Production and
service decisions will reside with the regional marketing vice president. The
Company anticipates placing Specialty Lines underwriters into approximately four
other of the Company's seven regional marketing offices during 1998.

      The Company uses a combination of Insurance Services Office, Inc. ("ISO")
coverage forms and rates and independently filed forms and rates. Coverage forms
and rates are independently developed in situations where the line of business
is not supported by ISO or where management believes the ISO forms and rates do
not adequately address the risk. Departures from ISO forms are also used to
differentiate the Company's products from its competitor's products and are
independently filed.

      The Company attempts to follow conservative underwriting and pricing
practices. When necessary, the Company is willing to reunderwrite, sharply
curtail or discontinue a product deemed to present unacceptable risks. Written
underwriting guidelines are maintained, and updated regularly, for all classes
of business underwritten. Adherence to underwriting guidelines is maintained
through underwriting audits. Product price levels are measured utilizing a price
monitoring system which measures the aggregate price level of the book of
business. This system is intended to assist management and underwriters in
recognizing and correcting price deterioration before it results in underwriting
losses.

REINSURANCE

      The Company's reinsurance program is principally placed with Swiss Re
America, an "A" (Excellent) rated company by A.M. Best Company, with which the
Company has maintained a reinsurance relationship since 1989.

      The Company's casualty reinsurance agreement with Swiss Re America (the
"Reinsurer") provides that the Company bears the first $500,000 layer of
liability on each occurrence with the Reinsurer bearing the remaining
contractual liability to policy limits of $1.0 million. Casualty risks in excess
of $1.0 million up to $6.0 million are reinsured under a casualty treaty
("Excess Treaty") placed through a reinsurance broker. Kemper Re, NAC Re, and
SCOR Re participate on the Excess Treaty at 50%, 25%, and 25%, respectively.
Each of these reinsurers is rated "A-" (Excellent) or better by A.M. Best
Company. Facultative reinsurance is placed for each casualty risk in excess of
$6.0 million.

      The Company also has an excess casualty reinsurance agreement with the
Reinsurer providing an additional $5.0 million of coverage for protection from
exposures such as extra-contractual obligations and judgments in excess of
policy limits. Additionally, the Company has an errors and omissions insurance
policy which provides an additional $5.0 million of coverage with respect to
these exposures.

      The Company's property reinsurance agreement provides that the Company
bears the first $500,000 layer of loss on each risk with the Reinsurer bearing
the next $1.5 million layer of loss on each risk subject to a maximum


                                       5
<PAGE>   6
of $3.5 million recoverable from a single occurrence. The Company has an
automatic facultative arrangement for each property risk in excess of $2.0
million up to $20.0 million.

      The Company seeks to limit the risk of a reinsurer's default in a number
of ways. First, the Company principally contracts with large reinsurers that are
rated at least "A-" (Excellent) by A.M. Best. Second, the Company seeks to
collect the obligations of its reinsurers on a timely basis. This collection
effort is supported by a reinsurance recoverable system that is regularly
monitored. Finally, the Company typically does not write casualty policies in
excess of $10.0 million nor property policies in excess of $20.0 million.

      The Company regularly assesses its reinsurance needs and seeks to improve
the terms of its reinsurance arrangements as market conditions permit. Such
improvements may involve increases in retentions, modifications in premium
rates, changes in reinsurers and other matters.

MARKETING AND DISTRIBUTION

      Proactive risk selection based on sound underwriting criteria and
relationship selling in clearly defined commercial markets continues to be the
foundation of the Company's marketing plan. Within this framework, the Company's
marketing effort is designed to assure a systematic and disciplined approach to
developing business which is anticipated to be profitable. The Company's most
important distribution channel is its production underwriting organization. The
production underwriting organization is currently comprised of 100 employees
located in 38 field offices in major markets across the country. The field
offices are focused daily on interacting with prospective and existing insureds.
In addition to this direct marketing, relationships with approximately 4,000
brokers have been formed either as a result of the broker having a relationship
with the insured, or through seeking the Company's expertise in one of its
specialty products.

      During 1996, the Company introduced its preferred agent program wherein
business relationships were formed with brokers specializing in certain of the
Company's business niches. At year end 1997, the Company had 35 preferred agent
relationships, representing approximately $16.2 million in gross written
premium. The Company anticipates increasing the number of these relationships by
approximately 35% in 1998 thereby further increasing the distribution of the
Company's niche products. This mixed marketing concept not only provides the
flexibility to work with the broker and/or policyholder but also provides the
flexibility to seize emerging market opportunities.

      The Company supplements its marketing efforts through trade shows, direct
mailings and national advertisements placed in trade magazines serving
industries in which the Company specializes.

      In 1997, approximately 85% of the Company's expiring insurance premiums
were renewed. Management attributes this renewal rate in large part to
continuing personal contacts between the Company's production underwriters,
value-added coverage enhancements which differentiates the Company's products,
and servicing its policyholders.

PRODUCT DEVELOPMENT

      The Company continually evaluates new product opportunities, consistent
with its strategic focus on selected market niches. Direct contacts between the
Company's field and home office personnel and its customers have produced a
number of new product ideas. All new product ideas are presented to the Product
Development Committee (the "Committee") for consideration. The Committee,
currently composed of the Company's two most senior executives, as well as
officers from the underwriting and claims departments, meets regularly to review
the feasibility of products from a variety of perspectives, including
underwriting risk, marketing and distribution, reinsurance, long-term viability
and consistency with the Company's culture and philosophy. For each new product,
an individualized test market plan is prepared, addressing such matters as the
appropriate distribution channel (e.g., a limited number of selected production
underwriters), an appropriate cap on premiums to be generated during the test
market phase and reinsurance requirements for the test market phase. Test market
products may involve lower retentions than customarily utilized. After a new
product is approved for test marketing, the Company monitors its success based
on specified criteria (e.g., underwriting results, sales success, product demand
and competitive pressures). If expectations are not realized, the Company either
moves to improve results by initiating adjustments or abandons the product.

CLAIMS MANAGEMENT AND ADMINISTRATION

      In accordance with its emphasis on underwriting profitability, the Company
actively manages claims under its policies in an effort to investigate reported
incidents at the earliest juncture, service insureds and minimize fraud. Claim
files are regularly audited by claims supervisors and the Company's reinsurers
in an attempt to ensure that claims are being processed properly and that
reserves are being set at appropriate levels. Claims examiners are expected to
set conservative reserves, an important factor in the Company's reserve
development over the years. See "Loss and Loss Adjustment Expenses."

      The Company maintains a Special Investigations Unit to investigate
suspicious claims and to serve as a clearinghouse for information concerning
fraudulent practices primarily within the rental car industry. Working closely
with a variety of industry contacts, including attorneys, investigators and
rental car company fraud units, this unit has uncovered a number of fraudulent
claims.

LOSS AND LOSS ADJUSTMENT EXPENSES

      The Company is liable for losses and loss adjustment expenses under its
insurance policies and reinsurance treaties. While the Company's professional
liability policies are written on claims-made forms and while claims on its
other policies are generally reported promptly after the occurrence of an
insured loss, in many cases several years may elapse between the occurrence of
an insured loss, the reporting of the loss to the Company and the Company's
payment of the loss. The Company reflects its liability for the ultimate payment
of all incurred losses and loss adjustment expenses by establishing loss and
loss adjustment expense reserves, which are balance sheet liabilities
representing estimates of future amounts needed to pay claims and related
expenses with respect to insured events that have occurred.

      When a claim involving a probable loss is reported, the Company
establishes a case reserve for the estimated amount of the Company's ultimate
loss and loss adjustment expense. This estimate reflects an informed judgment,
based on the Company's reserving practices and the experience of the Company's
claims staff. Management also establishes reserves on an aggregate basis to
provide for losses incurred but not reported ("IBNR"), as well as future
development on claims reported to the Company.

      As part of the reserving process, historical data are reviewed and
consideration is given to the anticipated effect of various factors, including
known and anticipated legal developments, changes in societal attitudes,
inflation and economic conditions. Reserve amounts are necessarily based on
management's estimates and judgments; as new data become available and are
reviewed, these estimates and judgments are revised, resulting in increases or
decreases to existing reserves. To verify the adequacy of its reserves, the
Company engages independent actuarial consultants to perform interim loss
reserve analyses and annual certifications.

      The following table sets forth a reconciliation of beginning and ending
reserves for unpaid loss and loss adjustment expenses, net of amounts for
reinsured losses and loss adjustment expenses, for the years indicated. As a
result of changes in estimates of insured events of prior years, the Company
reduced losses and loss adjustment expenses incurred by $1,716,000, $965,000 and
$925,000 in 1997, 1996 and 1995, respectively. Such favorable development was
due to losses emerging at a lesser rate than had been originally anticipated
when the initial reserves for the applicable accident years were estimated.

</TABLE>


      (1)   Unpaid loss and loss adjustment expenses differ from the amounts
            reported in the Consolidated Financial Statements because of the
            inclusion therein of reinsurance receivables of $13,502, $10,919 and
            $9,440 at December 31, 1997, 1996 and 1995, respectively.


      The following table presents the development of unpaid loss and loss
adjustment expenses, net of amounts for reinsured losses and loss adjustment
expenses, from 1987 through 1997. The top line of the table shows the estimated
reserve for unpaid loss and loss adjustment expenses at the balance sheet date
for each of the indicated years. These figures represent the estimated amount of
unpaid loss and loss adjustment expenses for claims arising in the current year
and all prior years that were unpaid at the balance sheet date, including IBNR
losses. The table also shows the re-estimated amount of the previously recorded
unpaid loss and loss adjustment expenses based on experience as of the end of
each succeeding year. The estimate changes as more information becomes known
about the frequency and severity of claims for individual years.

(1)   Unpaid loss and loss adjustment expenses differ from the amounts reported
      in the Consolidated Financial Statements because of the inclusion therein

      $1,770, $1,267, $1,672 and $1,591 at December 31, 1997, 1996, 1995, 1994,

      The cumulative redundancy represents the aggregate change in the reserve
estimated over all prior years, and does not present accident year loss
development. Therefore, each amount in the table includes the effects of changes
in reserves for all prior years.

      The unpaid loss and loss adjustment expense of PIIC and PIC, as reported
in their Annual Statements prepared in accordance with statutory accounting
practices and filed with state insurance departments, differ from those
reflected in the Company's financial statements prepared in accordance with
generally accepted accounting principles ("GAAP") with respect to recording the
effects of reinsurance. Unpaid loss and loss adjustment expenses under statutory
accounting practices are reported net of the effects of reinsurance whereas
under GAAP these amounts are reported without giving effect to reinsurance in
accordance with Statement of Financial Accounting Standards ("SFAS") No. 113.
Under GAAP, reinsurance receivables, with a corresponding increase in unpaid
loss and loss adjustment expense, have been recorded. (See footnote (1) on Page
9 for amounts). There is no effect on net income or shareholders' equity due to
the difference in reporting the effects of reinsurance between statutory
accounting practices and GAAP as discussed above.

OPERATING RATIOS

Statutory Combined Ratio

      The statutory combined ratio, which is the sum of (a) the ratio of loss
and loss adjustment expenses incurred to net earned premiums (loss ratio) and
(b) the ratio of policy acquisition costs and other underwriting expenses to net
written premiums (expense ratio), is the traditional measure of underwriting
experience for insurance companies. Generally, if the combined ratio is below
100%, an insurance company has an underwriting profit and if it is above 100%,
the insurer has an underwriting loss.

      The following table reflects the consolidated loss, expense and combined
ratios of the Insurance Subsidiaries together with the property and casualty
industry-wide combined ratios after policyholders' dividends.

Premium-to-Surplus Ratio:

      While there are no statutory provisions governing premium-to-surplus
ratios, regulatory authorities regard this ratio as an important indicator as to
an insurer's ability to withstand abnormal loss experience. Guidelines
established by the National Association of Insurance Commissioners (the "NAIC")
provide that an insurer's net premium-to-surplus ratio is satisfactory if it is
below 3 to 1.

      The following table sets forth, for the periods indicated, net written
premiums to policyholders' surplus for the Insurance Subsidiaries (statutory
basis):

INVESTMENTS

      At December 31, 1997, the Company had total investments with a carrying
value of $217.7 million, substantially all of which were held by the Insurance
Subsidiaries. At December 31, 1997, 78.4% of the Company's total investments
were investment grade fixed maturity securities, including U.S. treasury
securities and obligations of U.S. government corporations and agencies,
obligations of states and political subdivisions and corporate debt securities
including collaterized mortgage and asset backed securities totaling $18.6
million. The collaterized mortgage and asset backed securities consist of short
tranche securities possessing favorable pre-payment risk profiles. The remaining
21.6% of the Company's total investments consisted primarily of publicly-traded
common stock securities.

      Investments of the Insurance Subsidiaries must comply with applicable laws
and regulations which prescribe the type, quality and diversification of
investments. In general, these laws and regulations permit investments, with
specified limits and subject to certain qualifications, in federal, state and
municipal obligations, corporate bonds, preferred and common equity securities,
real estate mortgages and real estate.

      The Company's investment objective is to realize relatively high levels of
investment income while generating competitive after-tax total rates of return
within a prudent level of risk and within the constraints of maintaining
adequate securities in amount and duration to meet cash requirements of current
operations and long-term liabilities, as well as maintaining and improving the
Company's A.M. Best and Standard & Poor's ratings. The Company utilizes
professional investment managers for its fixed maturity and equity investment
portfolios. The portfolio consists of diversified issuers and issues and, as of
December 31, 1997, approximately 76% of the total invested assets (total
investments plus cash equivalents) consisted of investments in fixed maturity
securities.

      The Company increased its existing portfolio of fixed maturity securities
by investing in investment grade corporate debt during 1997 due to more
favorable after-tax yields. At the end of 1997, investment grade corporate debt
represented 19.6% of the total invested assets, compared to 6.0% as of the end
of 1996. The Company has also continued to increase its total investments in
common stock of quality growth oriented mid- and large-cap companies seeking to
achieve diversification and capital appreciation in the portfolio. At December
31, 1997, common stocks comprised 20.9% of the invested assets, compared to
15.8% as of the end of 1996.

REGULATION

      General: Insurance companies are subject to supervision and regulation in
the states in which they transact business. Such supervision and regulation,
designed primarily for the protection of policyholders and not shareholders,
relates to most aspects of an insurance company's business and includes such
matters as authorized lines of business; underwriting standards; financial
condition standards; licensing of insurers; investment standards; premium
levels; policy provisions; the filing of annual and other financial reports
prepared on the basis of Statutory Accounting Practices ("SAP"); the filing and
form of actuarial reports; the establishment and maintenance of reserves for
unearned premiums; losses and loss adjustment expenses; transactions with
affiliates; dividends; changes in control; and a variety of other financial and
nonfinancial matters. Because the Insurance Subsidiaries are domiciled in
Pennsylvania, the Pennsylvania Department of Insurance (the "Department") has
primary authority over the Company.

      Regulation of Insurance Holding Companies: Pennsylvania, like many other
states, has laws governing insurance holding companies (such as Philadelphia
Insurance). Under Pennsylvania law, a person generally must obtain the
Department's approval to acquire, directly or indirectly, 10% or more of the
outstanding voting securities of Philadelphia Insurance or either Insurance
Subsidiary. The Department's determination of whether to approve any such
acquisition is based on a variety of factors, including an evaluation of the
acquiror's financial stability, the competence of its management and whether
competition in Pennsylvania would be reduced.

      The Pennsylvania statute requires every Pennsylvania-domiciled insurer
which is a member of an insurance holding company system to register with the
Department by filing and keeping current a registration statement on a form
prescribed by the NAIC.


                                       12
<PAGE>   13
      The Pennsylvania statute also specifies that at least one-third of the
board of directors and each committee thereof, of either the domestic insurer or
its publicly owned holding company (if any), must be comprised of outsiders
(i.e., persons who are neither officers, employees nor controlling shareholders
of the insurer or any affiliate). In addition, the domestic insurer or its
publicly held holding company must establish one or more committees comprised
solely of outside directors, with responsibility for recommending the selection
of independent certified public accountants; reviewing the insurer's financial
condition, the scope and results of the independent audit and any internal
audit; nominating candidates for director; evaluating the performance of
principal officers; and recommending to the board the selection and compensation
of principal officers.

      Dividend Restrictions: As an insurance holding company, Philadelphia
Insurance will be largely dependent on dividends and other permitted payments
from the Insurance Subsidiaries to pay any cash dividends to its shareholders.
The ability of the Insurance Subsidiaries to pay dividends to the Company is
subject to Pennsylvania insurance laws, which currently require that dividends
be paid from profits and afford the Department 30 days to disapprove the payment
of "extraordinary dividends" from a domestic property and casualty insurer to
its shareholders (i.e., dividends over a twelve-month period that exceed the
greater of (a) 10% of policyholders' surplus shown on the latest Annual
Statement filed with the Department, or (b) the net income for the period
covered by such statement but in no event to exceed the amount of unassigned
funds (i.e., retained earnings plus or minus net unrealized gains or losses). In
addition, the law specifies factors to be considered by the Department to allow
it to determine that policyholders' surplus after the payment of dividends is
reasonable in relation to an insurance company's outstanding liabilities and
adequate to its financial needs. Such factors include, for example, the size of
the company, the extent to which its business is diversified among several lines
of insurance, the number and size of risks insured, the nature and extent of the
company's reinsurance, and the adequacy of the company's reserves. Accumulated
statutory profits of the Insurance Subsidiaries from which dividends may be paid
totaled $59.7 million at December 31, 1997. Of this amount, the Insurance
Subsidiaries are entitled to pay a total of approximately $14.3 million of
dividends in 1998 without obtaining prior approval from the Department.

      The National Association of Insurance Commissioners: In addition to
state-imposed insurance laws and regulations, the Insurance Subsidiaries are
subject to the general SAP and reporting formats established by the NAIC. The
NAIC also promulgates model insurance laws and regulations relating to the
financial and operational regulation of insurance companies. These model laws
and regulations generally are not directly applicable to an insurance company
unless and until they are adopted by applicable state legislatures or
departments of insurance. However, NAIC model laws and regulations have become
increasingly important in recent years, due primarily to the NAIC's state
regulatory accreditation program. Under this program, states which have adopted
certain required model laws and regulations and meet various staffing and other
requirements are "accredited" by the NAIC. Such accreditation is the cornerstone
of an eventual nationwide regulatory network and there is a certain degree of
political pressure on individual states to become accredited by the NAIC.
Because the adoption of certain model laws and regulations is a prerequisite to
accreditation, the NAIC's initiatives have taken on a greater level of practical
importance in recent years. The NAIC accredited Pennsylvania under the NAIC
Financial Regulation Standards in March 1994.

      All the states have adopted the NAIC's financial reporting form, which is
typically referred to as the NAIC "Annual Statement" and most states, including
Pennsylvania, generally defer to the NAIC with respect to SAP. In this regard,
the NAIC has a substantial degree of practical influence and is able to
accomplish certain quasi-legislative initiatives through amendments to the NAIC
annual statement and applicable accounting practices and procedures. For
instance, in recent years the NAIC has required all insurance companies to have
an annual statutory financial audit and an annual actuarial certification as to
loss reserves by including such requirements within the annual statement
instructions.

      Capital and Surplus Requirements: PIC's eligibility to write insurance on
a surplus lines basis in most jurisdictions is dependent on its compliance with
certain financial standards, including the maintenance of a requisite level of
capital and surplus and the establishment of certain statutory deposits. In
recent years, many jurisdictions have increased the minimum financial standards
applicable to surplus lines eligibility. For example, California and certain
other states have adopted regulations which require surplus lines companies
operating therein to maintain minimum capital of $15 million, calculated as set
forth in the regulations. PIC maintains capital to meet these requirements.


                                       13
<PAGE>   14
      Risk-Based Capital: Risk-based capital is designed to measure the
acceptable amount of capital an insurer should have based on the inherent
specific risks of each insurer. Insurers failing to meet this benchmark capital
level may be subject to scrutiny by the insurer's domiciliary insurance
department and ultimately rehabilitation or liquidation. Based on the standards
currently adopted, the policyholders' surplus at December 31, 1997 is in excess
of the prescribed risk-based capital requirements.

      Insurance Guaranty Funds: The Insurance Subsidiaries are subject to
guaranty fund laws which can result in assessments, up to prescribed limits, for
losses incurred by policyholders as a result of the impairment or insolvency of
unaffiliated insurance companies. Typically, an insurance company is subject to
the guaranty fund laws of the states in which it conducts insurance business;
however, companies which conduct business on a surplus lines basis in a
particular state are generally exempt from that state's guaranty fund laws.
During the five years ended December 31, 1997, the amount of such guaranty fund
assessments paid by the Company was not material.

      Shared Markets: As a condition of its license to do business in various
states, PIIC is required to participate in mandatory property-liability shared
market mechanisms or pooling arrangements which provide various insurance
coverages to individuals or other entities that otherwise are unable to purchase
coverage voluntarily provided by private insurers. In addition, some states
require automobile insurers to participate in reinsurance pools for claims that
exceed a certain amount. PIIC's participation in such shared markets or pooling
mechanisms is generally in amounts related to the amount of PIIC's direct
writings for the type of coverage written by the specific pooling mechanism in
the applicable state.

      Possible New Legislation, Regulations or Interpretations: New regulations
and legislation have been (and are being) proposed from time to time to limit
damage awards; to bring the industry under regulation by the federal government;
to control premiums, policy terminations and other policy terms; and to impose
new taxes and assessments. It is not possible to determine whether any of these
proposals will be adopted in any jurisdictions and, if so, in what form or in
what jurisdictions. In addition, the Company could be affected by
interpretations of state insurance regulators with respect to licensing
requirements applicable to the product distribution method currently utilized by
the rent a car companies that are customers of the Company. The impact of these
initiatives on the Company can not be determined.

COMPETITION

      The commercial property and casualty insurance industry is highly
competitive. Many of the Company's existing and potential competitors are
larger, have considerably greater financial and other resources, have greater
experience in the insurance industry and offer a broader line of insurance
products than the Company. Not only does the Company compete with other
insurers, it also competes with new forms of insurance organizations such as
risk retention groups and self-insurance mechanisms.

      Overall, due to the abundance of capital in the insurance industry, the
current business climate remains competitive from a solicitation and pricing
standpoint. In the context of the current environment, the Company will not
sacrifice pricing guidelines for premium volume and will "walk away" from
writing business that does not meet underwriting or pricing guidelines.
Management believes, though, that the Company's marketing strategy is a strength
in this market environment, in that it provides the flexibility to quickly
deploy the marketing efforts of the Company's direct production underwriters
from soft market segments to market segments with emerging opportunities.
Additionally, through the mixed marketing strategy, the Company's production
underwriters have established relationships with approximately 4,000 brokers,
thus increasing distribution and facilitating a regular flow of submissions.

EMPLOYEES

      As of February 26, 1998, the Company had 276 full-time employees and 15
part-time employees. The Company actively encourages its employees to continue
their educational efforts and aids in defraying their educational costs
(including 100% of education costs related to the insurance industry).
Management believes that the Company's relations with its employees are
generally excellent.

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


GENERAL

Operations

The Company reported record net income of $16.9 million for 1997, which is a
26.1% increase over its net income of $13.4 for 1996. This increase is
principally due to a 16.2% increase in gross written premiums, a 22.7% increase
in net investment income and profitable underwriting which resulted in a 85.9%
(GAAP basis) combined ratio (the sum of the net loss and loss adjustment
expenses and acquisition costs and other underwriting expenses divided by net
earned premiums). 1997 represented the fourth consecutive year since its 1993
initial public offering that the Company has reported growth in gross written
premiums and net income while experiencing a combined ratio under 90%, which is
substantially lower than the commercial property and casualty insurance industry
as a whole. The Company believes that its continued profitable growth is
attributable to the adherence to the Company's core philosophy of conservative
underwriting guidelines and pricing discipline.

The growth in gross written premiums primarily resulted from: the Company's
recent new product offerings; strengthening of the proprietary field marketing
organization to 100 professionals at year end 1997; and increasing product
distribution through the preferred agent program.

The Company's insurance subsidiaries are rated "A" (Excellent) by A.M. Best
Company and have been assigned an "A" claims paying ability rating by Standard &
Poor's.

Investments

The Company's investment objective is to realize relatively high levels of
investment income while generating competitive after-tax total rates of return
within a prudent level of risk and within the constraints of maintaining
adequate securities in amount and duration to meet cash requirements of current
operations and long-term liabilities, as well as maintaining and improving the
Company's A.M. Best and Standard & Poor's ratings. The Company utilizes
professional investment managers for its fixed maturity and equity investments.
These investments consist of diversified issuers and issues, and as of December
31, 1997 approximately 76% of the total invested assets (total investments plus
cash equivalents) consisted of investments in fixed maturity securities.

The Company increased its existing portfolio of fixed maturity securities by
investing in investment grade corporate debt during 1997 due to more favorable
after-tax yields. At the end of 1997 investment grade corporate debt represented
19.6% of total invested assets, compared to 6.0% as of the end of 1996. The
Company has also continued to increase its investments in common stock of
quality growth oriented mid- and large-cap companies seeking to achieve
diversification and capital appreciation in its invested assets. At December 31,
1997, common stocks comprised 20.9% of invested assets, compared to 15.8% as of
the end of 1996.

During 1997, the Company purchased certain collaterized mortgage and asset
backed securities, totaling $18.6 million in market value at year end. These
securities are short tranche securities possessing favorable prepayment risk
profiles. The Company had no other derivative financial instruments in its total
investments as of December 31, 1997.


RESULTS OF OPERATIONS
(1997 VERSUS 1996)

      Premiums: Gross written premiums grew $22.2 million (16.2%) to $159.1
million in 1997 from $136.9 million in 1996; gross earned premiums grew $28.3
million (23.2%) to $150.1 million in 1997 from $121.8 million in 1996; net
written premiums increased $27.8 million (33.1%) to $111.8 million in 1997 from
$84.0 million in 1996; and net earned premiums grew $28.5 million (39.5%) to
$100.6 million in 1997 from $72.1 million in 1996. The overall growth in
premiums and the varying growth rates for gross written premiums, gross earned
premiums, net written premiums and net earned premiums are attributable to a
number of factors including:


                                       18
<PAGE>   19
- -     Overall premium growth is primarily attributable to: continued marketing
      efforts relating to commercial auto, commercial package, and specialty
      lines products, along with the continued development of the Company's
      Preferred Agent Program, initiated in 1996, wherein business relationships
      are formed with brokers specializing in certain of the Company's business
      niches thereby increasing the distribution of the Company's niche
      products; the increase of the Company's proprietary field organization to
      a total of 100 professionals, production underwriters and customer service
      representatives.

- -     Net written and net earned premiums grew at higher rates than gross
      written and gross earned premiums primarily due to the renegotiation of
      the Company's reinsurance program effective January 1, 1997 whereby more
      favorable reinsurance rates were realized while substantially the same
      retentions and coverages were maintained.

      Net Investment Income: Net investment income approximated $9.7 million in
1997 and $7.9 million in 1996. The increase of $1.8 million (22.8%) is due
primarily to the increase in total investments as a result of cash flows
provided from operating activities and the additional investment income as a
result of the relative percentage increase in corporate taxable securities
versus tax exempt municipal securities.

      Net Loss and Loss Adjustment Expenses: Net loss and loss adjustment
expenses increased $14.9 million (37.2%) to $55.0 million in 1997 from $40.1
million in 1996 and the loss ratio decreased to 54.7% in 1997 from 55.7% in
1996. The increase in net loss and loss adjustment expenses was due primarily to
the 39.5% growth in net earned premiums. Additionally, since more earned premium
was retained from the lower cost of reinsurance (see "Premiums", above), there
was relatively higher net earned premium growth on products with low loss
experience, the 37.2% increase in net loss and loss adjustment expenses was
lower than the 39.5% net earned premium growth.

      Acquisition Costs and Other Underwriting Expenses: Acquisition costs and
other underwriting expenses increased $9.1 million (41.0%), to $31.3 million in
1997 from $22.2 million in 1996. This increase was due primarily to the 39.5%
growth in net earned premiums.

      Income Tax Expense: The Company's effective tax rates for 1997 and 1996
were 24.0% and 20.3%, respectively. The effective rates differed from the 35%
statutory rate principally due to investment income earned on tax-exempt
securities. The increase in the effective tax rate is principally due to a
greater investment in taxable securities relative to tax-exempt securities
during 1997.

RESULTS OF OPERATIONS
(1996 VERSUS 1995)

      Premiums: Gross written premiums grew $32.7 million (31.4%) to $136.9
million in 1996 from $104.2 million in 1995; gross earned premiums grew $22.3
million (22.4%) to $121.8 million in 1996 from $99.5 million in 1995; net
written premiums increased $21.9 million (35.3%) to $84.0 million in 1996 from
$62.1 million in 1995; and net earned premiums grew $13.9 million (23.9%) to
$72.1 million in 1996 from $58.2 million in 1995. The overall growth in premiums
and the varying growth rates for gross written premiums, gross earned premiums,
net written premiums and net earned premiums are attributable to a number of
factors:

- -     Overall premium growth is primarily attributable to the following factors:

      -       The prior year's growth in the field production underwriting
              organization enabling expansion of the Company's marketing efforts
              to non profit organizations, the health and fitness industry and
              selected professional liability products.

      -       The introduction of the Company's Preferred Agent Plan, wherein,
              business relationships were formed with brokers specializing in
              certain of the Company's business niches, thereby increasing the
              distribution of the Company's niche products.

      -       Continued favorable market conditions for certain leasing 
              products.

        -     Overall premium growth has been offset in part by designed
              reductions in premiums from certain rental products due primarily
              to inadequate pricing levels which are currently being experienced
              as a result of market competition. However, the Company
              anticipates an improvement in these market conditions in the near
              future. Additionally, there have been recent consolidations in the
              car rental industry the effect of which on the rental car
              insurance market, if any, are not known at this time.

      Net Investment Income: Net investment income approximated $7.9 million in
1996 and $6.5 million in 1995. The increase of $1.4 million (21.5%) is due
primarily to the increase in total investments as a result of cash flows
provided from operating activities.

      Net Realized Investment Gain (Loss): Net realized investment gains were
$.3 million in 1996 compared to $.2 million in 1995.

      Net Loss and Loss Adjustment Expenses: Net loss and loss adjustment
expenses increased $6.9 million (20.8%) to $40.1 million in 1996 from $33.2
million in 1995 and the loss ratio decreased to 55.7% in 1996 from 57.1% in
1995. The increase in net loss and loss adjustment expenses was due primarily to
the 23.9% growth in net earned premiums. Additionally, since there was
relatively higher net earned premium growth on products with low loss
experience, the percentage increase in net loss and loss adjustment expenses
(20.8%) was lower than the 23.9% net earned premium growth.

      Acquisition Costs and Other Underwriting Expenses: Acquisition costs and
other underwriting expenses increased $5.1 million (29.8%), to $22.2 million in
1996 from $17.1 million in 1995. The increase in acquisition costs and other
underwriting expenses exceeds the 23.9% growth in net earned premiums, due
primarily to increased commission expense as a result of the Company beginning
to market its niche products through preferred brokers.

      Other Operating Expenses: Other operating expenses decreased $1.2 million
(46.2%), to $1.4 million in 1996 compared to $2.6 million in 1995 principally
due to additional expenses related to the opening of new field offices in 1995.

      Income Tax Expense: The Company's effective tax rates for 1996 and 1995
were 20.3% and 20.0%, respectively. The effective rates differed from the 34%
statutory rate principally due to investment income earned on tax-exempt
securities.


GROWTH OPPORTUNITIES

The attainment of profitable new business continues to be a primary focus of the
Company. For 1998, the Company anticipates substantially growing its Preferred
Agent program, thereby further increasing the distribution of the Company's
niche products. In addition, the Company has grown its proprietary field
organization during 1997 to 100 professionals, including production underwriters
and customer service representatives and plans to further expand this
organization in 1998, thereby further strengthening its resources to prospect
the Company's existing niches for profitable new business. The Company also
seeks acquisition opportunities to purchase programs or books of business which
complement its niche markets or parallel its conservative underwriting and
pricing discipline. The Company is also exploring financing opportunities in
this regard; however, there is no assurance that an acquisition or financing
will occur.

Overall, due to the abundance of capital in the insurance industry, the current
business climate remains very competitive from a solicitation and pricing
standpoint. In the context of the current environment, the Company will not
sacrifice underwriting standards or pricing guidelines solely for premium volume
and will "walk away", if necessary, from writing business that does not meet
established underwriting standards and pricing guidelines as has occurred in the
commercial auto niche over the past three years. Additionally, in response to
the competitive market, the Company re-underwrote its errors and omissions
product during 1997 by increasing deductible requirements and modifying
underwriting guidelines in certain markets to reduce the size and risk profile
of the product. Management believes, though, that the Company's mixed marketing
strategy is a strength in this market environment, in that, it provides the
flexibility to quickly deploy the marketing efforts of the Company's direct
production underwriters from soft market segments to market segments with
emerging opportunities. Additionally,


                                       20
<PAGE>   21
through the mixed marketing strategy, the Company's production underwriters have
established relationships with approximately 4,000 brokers, thus facilitating a
regular flow of submissions.


LIQUIDITY AND CAPITAL RESOURCES

Philadelphia Insurance is a holding company whose principal assets currently
consist of 100% of the capital stock of the Insurance Subsidiaries and Maguire
Insurance Agency, Inc. Philadelphia Insurance's primary sources of funds are
dividends from its subsidiaries and payments to it pursuant to tax allocation
agreements with the Insurance Subsidiaries. For the year ended December 31,
1997, payments to Philadelphia Insurance pursuant to such tax allocation
agreements totaled $7.3 million. The payment of dividends to Philadelphia
Insurance from the Insurance Subsidiaries is subject to certain limitations
imposed by the insurance laws of the Commonwealth of Pennsylvania. Statutory
profits of the Insurance Subsidiaries from which dividends may be paid totaled
$59.7 million at December 31, 1997. Of this amount, the Insurance Subsidiaries
are entitled to pay a total of approximately $14.3 million of dividends in 1998
without obtaining prior approval from the Insurance Commissioner of the
Commonwealth of Pennsylvania.

Under certain reinsurance agreements, the Company is required to maintain
investments in trust accounts to secure its reinsurance obligations (primarily
the payment of losses and loss adjustment expenses on business it does not write
directly). At December 31, 1997, the investment and cash balances in such trust
accounts totaled approximately $14.6 million. In addition, various insurance
departments of states in which the Company operates require the deposit of funds
to protect policyholders within those states. At December 31, 1997, the balance
on deposit for the benefit of such policyholders totaled approximately $10.9
million.

The Company has reviewed all computer systems in operation within the Company
and determined them to be Year 2000 compliant except for its mainframe policy
administration computer system. The Company will begin the process of preparing
this computer system and related applications for the Year 2000 in the second
quarter 1998. The process involves modifying certain hardware and software.
Management expects to have substantially all hardware and software upgraded as
necessary, for compliance by year-end 1998. Management believes that its level
of preparedness is appropriate. The Company estimates the cumulative costs of
the process, which includes costs of modifying hardware and software, will not
have a material effect on its business, operations or financial condition. The
costs of the project and expected completion dates are based on management's
best estimates.

The Company has produced net cash from operations of $38.0 million in 1997,
$37.6 million in 1996 and $25.2 million in 1995. Management believes that the
Company has adequate liquidity to pay all claims and meet all other cash needs.

The Insurance Subsidiaries, which operate under a pooling agreement, require
policyholders' surplus to support premium writings. Guidelines of the National
Association of Insurance Commissioners (the "NAIC") suggests that a property and
casualty insurer's ratio of annual statutory net premium written to
policyholders' surplus should not exceed 3 to 1. The ratio of combined annual
statutory net premium written by the Insurance Subsidiaries to their combined
policyholders' surplus was 1.0 to 1.0 for both 1997 and 1996. Management
believes that the policyholders' surplus, which was $106.0 million at December
31, 1997 will be sufficient to support current and anticipated premium writings.
Risk-based capital is designed to measure the acceptable amount of capital and
surplus an insurer should have based on the inherent specific risks of each
insurer. Insurers failing to meet this benchmark level may be subject to
scrutiny by the insurer's domiciliary insurance department and ultimately
rehabilitation or liquidation. Based on the standards currently contained in the
applicable Pennsylvania Insurance Company statutes, the Company's capital and
surplus is in excess of the prescribed risk-based capital requirements.

INFLATION

Property and casualty insurance premiums are established before the amount of
losses and loss adjustment expenses, or the extent to which inflation may affect
such amounts, is known. The Company attempts to anticipate the potential impact
of inflation in establishing its premiums and reserves. Substantial future
increases in inflation could result in future increases in interest rates which
in turn is likely to result in a decline in the market value of the Company's
investment portfolio and resulting unrealized losses and/or reductions in
shareholders' equity.

NEW ACCOUNTING PRONOUNCEMENTS

In February 1997, the Financial Accounting Standards Board issued Statement of
Financial Accounting Standards (SFAS) No. 128, "Earnings per Share", specifying
the computation, presentation, and disclosure requirements for earnings per
share for entities with publicly held common stock. Under SFAS No. 128, basic
and diluted per share amounts shall be presented for net income on the face of
the statement of operations. Basic earnings per share excludes dilution and is
computed by dividing income available to common shareholders by the
weighted-average number of common shares outstanding for the period. Diluted
earnings per share reflects the potential dilution that could occur if
securities or other contracts to issue common stock were exercised or converted
into common stock or resulted in the issuance of common stock that then shared
in the earnings of the entity. The Company adopted the provisions of SFAS No.
128 as of December 31, 1997.

In June 1997, the Financial Accounting Standards Board issued SFAS No. 130,
"Reporting Comprehensive Income", which is effective for years beginning after
December 15, 1997. This statement establishes standards for the reporting and
display of comprehensive income and its components. Comprehensive income is
defined to include all changes in equity during a period except those resulting
from investments by owners and distributions to owners. The Company will adopt
SFAS No. 130 and begin reporting comprehensive income in the first quarter of
1998.

In June 1997, the Financial Accounting Standards Board also issued SFAS No. 131,
"Disclosures about Segments of an Enterprise and Related Information", which is
effective for fiscal years beginning after December 15, 1997. This statement
establishes standards for the disclosure of segment results. It requires that
segments be determined using the "management approach", which means the way
management organizes the segments within the enterprise for making operating
decisions and assessing performance. The Company will adopt SFAS No. 131 in the
fourth quarter of 1998, and is still evaluating its impact on the Company's
segment disclosures.

FORWARD-LOOKING INFORMATION

From time-to-time, the Company may publish statements which are not historical
facts but are forward-looking statements relating to such matters as anticipated
financial performance, business prospects, technological developments, new and
existing products, expectations for market segment and growth, and similar
matters. In connection with the "safe harbor" provisions of the Private
Securities Litigation Reform Act of 1995, the Company provides the following
cautionary remarks regarding important factors which, among others, could cause
the Company's actual results and experience to differ materially from the
anticipated results or other expectations expressed in the Company's
forward-looking statements.

The risks and uncertainties that may affect the operations, performance,
development, results of the Company's business and the other matters referred to
above include, but are not limited to: (i) changes in the business environment
in which the Company operates, including inflation and interest rates; (ii)
changes in taxes, governmental laws and regulations; (iii) competitive product
and pricing activity; and (iv) difficulties of managing growth profitably.

TO THE SHAREHOLDERS AND BOARD OF DIRECTORS OF PHILADELPHIA CONSOLIDATED HOLDING
CORP.:


We have audited the accompanying consolidated balance sheets of Philadelphia
Consolidated Holding Corp. and Subsidiaries as of December 31, 1997 and 1996 and
the related consolidated statements of operations, changes in shareholders'
equity and cash flows for each of the three years in the period ended December
31, 1997. These consolidated financial statements are the responsibility of the
Company's management. Our responsibility is to express an opinion on these
consolidated financial statements based on our audits.

We conducted our audits in accordance with generally accepted auditing
standards. Those standards 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. An audit also includes
assessing the accounting principles used and significant estimates made by
management, as well as evaluating the overall financial statement presentation.
We believe that our audits provide a reasonable basis for our opinion.

In our opinion, the consolidated financial statements referred to above present
fairly, in all material respects, the consolidated financial position of
Philadelphia Consolidated Holding Corp. and Subsidiaries as of December 31, 1997
and 1996 and the consolidated results of their operations and their cash flows
for each of the three years in the period ended December 31, 1997 in conformity
with generally accepted accounting principles.

            PHILADELPHIA CONSOLIDATED HOLDING CORP. AND SUBSIDIARIES

                   NOTES TO CONSOLIDATED FINANCIAL STATEMENTS

1. GENERAL INFORMATION AND SIGNIFICANT ACCOUNTING POLICIES

Philadelphia Consolidated Holding Corp. ("Philadelphia Insurance"), and its
subsidiaries (collectively the "Company") doing business as Philadelphia
Insurance Companies, include two Pennsylvania domiciled property and casualty
insurance companies, Philadelphia Indemnity Insurance Company and Philadelphia
Insurance Company ("Insurance Subsidiaries"), and an underwriting manager
Maguire Insurance Agency, Inc. The Company designs, markets, and underwrites
specialty commercial property and casualty insurance products for the rent a car
industry, automobile leasing industry, non-profit organizations, the health,
fitness and wellness industry, and selected classes of professional liability.
All marketing, underwriting, claims management, investment, and general
administration is provided by the underwriting manager.

PRINCIPLES OF CONSOLIDATION AND BASIS OF PRESENTATION

The consolidated financial statements include the accounts of the Company
prepared in conformity with generally accepted accounting principles. All
significant intercompany balances and transactions have been eliminated in
consolidation. The preparation of financial statements requires making 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 could differ from those estimates. Certain
prior years' amounts have been reclassified for comparative purposes.

(a)  INVESTMENTS

Investments classified as Available for Sale are carried at market value with
the change in unrealized appreciation (depreciation) credited or charged
directly to shareholders' equity, net of applicable deferred income taxes.
Income on fixed maturities is recognized on the accrual basis.

The decision to purchase or sell investments is based on management's assessment
of various factors such as foreseeable economic conditions, including current
interest rates and the interest rate risk, and the liquidity and capital
positions of the Company.

Investments in fixed maturities are adjusted for amortization of premiums and
accretion of discounts to maturity date, except for collaterized mortgage and
asset backed securities which are adjusted for amortization of premiums and
accretion of discounts over their estimated lives. Certain collaterized mortgage
and asset backed securities repayment patterns will change based on interest
rate movements and, accordingly, could impact future investment income if the
reinvestment of the repayment amounts are at lower interest rates than the
underlying securities. Collaterized mortgage and asset backed securities
amounted to $18,630,800 and $0 at December 31, 1997 and December 31, 1996,
respectively. The collaterized mortgage and asset back securities held as of
December 31, 1997 are short tranche securities possessing favorable prepayment
risk profiles.

Equity securities are carried at market value with the change in unrealized
appreciation (depreciation) credited or charged directly to shareholders'
equity, net of applicable deferred income taxes.

Realized investment gains and losses are calculated on the specific
identification basis and recorded as income when the securities are sold.

(b)  CASH AND CASH EQUIVALENTS

Cash equivalents, consisting of fixed maturity investments with maturities of
three months or less when purchased and money market funds, are stated at cost
which approximates market value.

(c) DEFERRED ACQUISITION COSTS

Policy acquisition costs, which include commissions, premium taxes, fees and
other costs of underwriting policies, are deferred and amortized over the same
period in which the related premiums are earned. Deferred acquisition costs are
limited to the estimated amounts recoverable after providing for losses and
expenses that are expected to be incurred, based


                                       29
<PAGE>   30
upon historical and current experience, as the premiums are earned. Amortization
of policy acquisition costs in the accompanying consolidated statements of
operations was $25,034,000, $17,739,000 and $13,662,000 for the years ended
December 31, 1997, 1996 and 1995, respectively.

(d)  PROPERTY AND EQUIPMENT

Property and equipment are recorded at cost and depreciated using the
straight-line method over the estimated useful lives of the respective assets.
Costs incurred in developing information systems technology are capitalized and
included in property and equipment. These costs are amortized over their useful
lives from the dates the systems technology became operational. Upon disposal of
assets, the cost and related accumulated depreciation are removed from the
accounts and the resulting gain or loss is included in earnings.

(e)  RESERVES FOR UNPAID LOSS AND LOSS ADJUSTMENT EXPENSES

The liability for unpaid loss and loss adjustment expenses includes an amount
determined on the basis of claims adjusters' evaluations and an amount, based on
past experience, for losses incurred but not reported. Such liabilities are
necessarily based on estimates, and while management believes that the amount is
adequate, the ultimate liability may be in excess of, or less than, the amount
provided. The methods of making such estimates and establishing the resulting
liabilities are continually reviewed and updated and any adjustments resulting
therefrom are reflected in operations currently.

(f)  UNEARNED PREMIUMS

Premiums are generally earned on a pro rata basis over the terms of the
policies. Premiums applicable to the unexpired terms of the policies in-force
are reported as unearned premiums.

(g)  REINSURANCE CEDED

In the normal course of business, the Company seeks to reduce the loss that may
arise from events that cause unfavorable underwriting results by reinsuring
certain levels of risk in various areas of exposure with reinsurers. Amounts
recoverable from reinsurers are estimated in a manner consistent with the
reinsured policy. Amounts for reinsurance assets and liabilities are reported
gross.

(h)  INCOME TAXES

The Company files a consolidated federal income tax return. Deferred income
taxes are recognized for the tax consequences of temporary differences by
applying enacted statutory tax rates applicable to the differences between the
financial statement carrying amounts and the tax bases of existing assets and
liabilities. The effect on deferred taxes for a change in tax rates is
recognized in income in the period that includes the enactment date (see Note
8).

(i)  EARNINGS PER SHARE

Earnings per share and common stock equivalents outstanding have been
retroactively restated to reflect the increased number of common shares
resulting from a two for one stock split that was announced in October 1997 and
distributed to shareholders on November 5, 1997. A total of 6,119,716 additional
shares were issued as a result of the stock split. The par value of the
Company's stock remained unchanged.

In February 1997, the Financial Accounting Standards Board issued Statement of
Financial Accounting Standards (SFAS) No. 128, "Earnings per Share," specifying
the computation, presentation, and disclosure requirements for earnings per
share for entities with publicly held common stock. Under SFAS No. 128, basic
and diluted per share amounts shall be presented for net income on the face of
the statement of operations. Basic earnings per share excludes dilution and is
computed by dividing income available to common shareholders by the
weighted-average number of common shares outstanding for the period. Diluted
earnings per share reflects the potential dilution that could occur if
securities or other contracts to issue common stock were exercised or converted
into common stock or resulted in the issuance of common stock that then shared
in the earnings of the entity. The Company adopted the provisions of SFAS No.
128 as of December 31, 1997 and restated all prior period earnings per share
data to conform with the provisions of this Statement.

2.  STATUTORY INFORMATION

Accounting Principles. The Philadelphia Indemnity Insurance Company ("PIIC") and
the Philadelphia Insurance Company ("PIC") are domiciled in the Commonwealth of
Pennsylvania. PIIC and PIC are required to report to certain regulatory agencies
on the basis of Statutory Accounting Practices ("SAP"). The statutory financial
statements are prepared in accordance with accounting practices prescribed or
permitted by the Insurance Department of the Commonwealth of Pennsylvania.
Prescribed statutory accounting practices include a variety of publications of
the National Association of Insurance Commissioners ("NAIC"), as well as
Commonwealth laws, regulations and general administrative rules. Permitted
Statutory Accounting Practices encompass all accounting practices not so
prescribed.

Generally accepted accounting principles ("GAAP") differ in certain respects
from SAP prescribed or permitted by the Insurance Department of the Commonwealth
of Pennsylvania. The principal differences between SAP and GAAP are as follows:

      Under SAP, investments in debt securities are carried at amortized cost,
      while under GAAP, investments in debt securities classified as Available
      for Sale are carried at fair value;

      Under SAP, policy acquisition costs, such as commissions, premium taxes,
      fees, and other costs of underwriting policies are charged to current
      operations as incurred, while under GAAP, such costs are deferred and
      amortized on a pro rata basis over the period covered by the policy;

      Under SAP, certain assets, designated as "Non-admitted Assets" (such as
      prepaid expenses) are charged against surplus;

      Under SAP, federal income taxes are only provided on taxable income for
      which income taxes are currently payable, while under GAAP, deferred
      income taxes are provided with respect to temporary differences;

      Under SAP, certain reserves are established in amounts which differ from
      amounts which would be provided in conformity with GAAP.

Financial Information: The statutory capital and surplus of PIIC as of December
31, 1997 and 1996 was $75,894,000 and $60,175,000, respectively. Statutory net
income of PIIC for the years ended December 31, 1997, 1996 and 1995 was
$8,839,000, $5,626,000, and $5,416,000, respectively.

The statutory capital and surplus of PIC as of December 31, 1997 and 1996 was
$30,091,000 and $21,732,000, respectively. Statutory net income of PIC for the
years ended December 31, 1997, 1996 and 1995 was $5,494,000, $3,629,000, and
$3,587,000, respectively.

Dividend Restrictions: The Insurance Subsidiaries are subject to various
regulatory restrictions which limit the maximum amount of annual shareholder
dividends allowed to be paid. The maximum dividend which PIIC may pay to
Philadelphia Insurance during 1998 without prior approval is $8,839,000 and the
maximum dividend which PIC may pay to Philadelphia Insurance during 1998 without
prior approval is $5,494,000.

Risk-Based Capital: Risk-based capital is designed to measure the acceptable
amount of capital an insurer should have based on the inherent specific risks of
each insurer. Insurers failing to meet this benchmark capital level may be
subject to scrutiny by the insurer's domiciliary insurance department and
ultimately rehabilitation or liquidation. Based on the standards, PIIC's and
PIC's capital and surplus at December 31, 1997 is in excess of the prescribed
risk-based capital requirements.

4.  RESTRICTED ASSETS

PIIC and PIC have investments, principally U.S. Treasury securities on deposit
with the various states in which they are licensed insurers. At December 31,
1997 and 1996 the carrying value on deposit totaled $10,912,000 and $7,070,000,
respectively.

5.  TRUST ACCOUNTS

The Company is required to maintain certain investments in trust accounts under
reinsurance agreements with unrelated insurance companies that cede insurance
risks to the Company. At December 31, 1997 and 1996 the Company had investments
with a carrying value of $2,403,000 and $2,868,000, respectively, in trust
accounts pursuant to a terminated quota share reinsurance agreement. Under the
terms of this agreement, net premiums received by the Company were invested and
held in a trust account to pay future claims. Interest income on these
investments is distributed to the parties to the quota share agreement on a
quarterly basis. The Company receives its interest in net trust investments in
accordance with a formula that specifies certain percentages of funds to be
released over a five-year period as losses are settled.

The Company also maintains investments in trust accounts under current
reinsurance agreements with unrelated insurance companies. These investments
collateralize the Company's obligations under the reinsurance agreements. The
Company possesses sole responsibility for investment and reinvestment of the
trust account assets. All dividends, interest, and other income resulting from
investment of these assets are owned by the Company, and are distributed on a
monthly basis. At December 31, 1997 and 1996 the carrying value of these trust
fund investments were $12,205,000 and $23,223,000, respectively.

The Company's share of the investments in the trust accounts is included in
investments and cash equivalents, as applicable, in the accompanying
consolidated balance sheets.

As a result of changes in estimates of insured events of prior years, the
Company reduced losses and loss adjustment expenses incurred by $1,716,000,
$965,000 and $925,000 in 1997, 1996 and 1995, respectively. Such favorable
development was due to losses emerging at a lesser rate than had been originally
anticipated when the initial reserves for the applicable accident years were
estimated.

</TABLE>

As of December 31, 1997, the Company has approximately $0.9 million in net
operating loss carryforwards, which expire in 2000 and 2001, available to offset
future taxable income. Utilization of the loss carryfowards is limited to an
annual amount of $336,000. For financial reporting purposes, the tax benefit of
any utilization of these operating loss carryfowards is applied to reduce
goodwill ($114,000 in 1997) and does not reduce income tax expense.

Philadelphia Insurance has entered into tax sharing agreements with each of its
subsidiaries. Under the terms of these agreements, the income tax provision is
computed as if each subsidiary were filing a separate federal income tax return
including adjustments for the income tax effects of net operating losses and
other special tax attributes regardless of whether those attributes are utilized
in the Company's consolidated federal income tax return.

9.  REINSURANCE

In the normal course of business, the Company has entered into various
reinsurance contracts with unrelated reinsurers. The Company participates in
such agreements for the purpose of limiting loss exposure and diversifying
business. Reinsurance contracts do not relieve the Company from its obligation
to policyholders.

The loss and loss adjustment expense reserves ceded under such arrangements were
$13,502,000 and $10,919,000 at December 31, 1997 and 1996, respectively. The
Company evaluates the financial condition of its reinsurers to minimize its
exposure to losses from reinsurer insolvencies. The percentage of ceded
reinsurance reserves that are with companies rated "A" (Excellent) or better by
A.M. Best Company is 100% and 97% as of December 31, 1997 and 1996,
respectively. Additionally, approximately 2%, 4%, and 11% of the Company's net
written premiums for the years ended December 31, 1997, 1996 and 1995,
respectively, were assumed from an unrelated reinsurance company.

10.      SHAREHOLDERS' EQUITY

The Company has established non-qualified stock bonus and stock option plans.
Under the stock bonus plan, the Company has granted a total of 137,500 shares to
certain officers of the Company, of which all such shares have been issued and
are vested.

Under the Company's stock option plan, stock options may be granted for the
purchase of common stock at a price not less than the fair market value on the
date of grant. Options outstanding as of December 31, 1994 are exercisable over
a four to five year vesting period. Options issued in 1997, 1996 and 1995 are
exercisable after the expiration of five years following the grant date. Under
this plan, the Company has reserved 2,475,000 shares of common stock for
issuance pursuant to options granted under the plan.

In addition to stock options granted pursuant to the Company's stock option
plan, the Company's Board of Directors have granted previous awards of 2,613,492
stock options.

SFAS No. 123, "Accounting for Stock-Based Compensation," encourages, but does
not require, companies to record compensation cost for stock-based employee
compensation plans at a fair value. The Company has chosen to continue to
account for stock-based compensation using the intrinsic value method prescribed
in Accounting Principles Board Opinion No. 25, "Accounting for Stock Issued to
Employees" and related interpretations. Accordingly, compensation cost for the
Company's compensation instruments is measured as the excess, if any, of the
quoted market price of the Company's stock at the date of the grant over the
amount an employee must pay to acquire the stock.

The Company has established a non-qualified Employee Stock Purchase Plan (the
"Stock Purchase Plan"). The aggregate maximum number of shares that may be
issued pursuant to the Stock Purchase Plan is 500,000. Shares may be purchased
under the Stock Purchase Plan by eligible employees during designated one-month
offering periods established by the Compensation Committee of the Board of
Directors at a purchase price of the lesser of 85% of the fair market value of
the shares on the first business day of the offering period or the date the
shares are purchased. The purchase price of shares may be paid by the employee
over six years pursuant to the execution of a promissory note. The promissory
note(s) are collateralized by such shares purchased under the Stock Purchase
Plan and are interest free. Under the Stock Purchase Plan, the Company issued
78,569 and 52,144 shares in 1997 and 1996, respectively. The weighted average
fair value of those purchase rights granted in 1997 and 1996 was $1.94 and
$1.51, respectively.

In addition, the Company has also established a non-qualified Directors Stock
Purchase Plan ("Directors Plan") for the benefit of non-employee Directors. The
aggregate maximum number of shares that may be issued pursuant to the Directors
Plan is 50,000. Non-employee Directors, during monthly offering periods, may
designate a portion of his or her fees to be used for the purchase of shares
under the terms of the Directors Plan at a purchase price of the lesser of 85%
of the fair market value of the shares on the first business day of the offering
period or the last business day of the offering period. No shares have been
issued pursuant to the Directors Plan as of December 31, 1997.

11.   COMMON STOCK SPLIT

On October 16, 1997, the Board of Directors approved a two for one split of the
Company's common stock payable to shareholders of record on October 27, 1997 for
distribution on November 5, 1997. Weighted average common shares outstanding,
common stock equivalents, and earnings per share have been restated to reflect
this stock split.

12.  PROFIT SHARING

The Company has a defined contribution Profit Sharing Plan, which includes a
401K feature, covering substantially all employees. Under the plan, employees
may contribute up to an annual maximum of the lesser of 15% of eligible
compensation or the applicable Internal Revenue Code limit in a calendar year.
The Company makes a matching contribution in an amount equal to 50% of the
participant's pretax contribution, subject to a maximum of 6% of the
participant's eligible compensation. The Company may also make annual
discretionary profit sharing contributions at each plan year end. Participants
are fully vested in the Company's contribution upon completion of 7 years of
service. The Company's contributions to the plan were $474,300, $322,400, and
$267,500 in 1997, 1996 and 1995, respectively.

                            FIRST AMENDMENT TO LEASE


         THIS FIRST AMENDMENT TO LEASE ("Amendment") is made on this 8th day of
May, 1997, by and between BALA PLAZA, INC., a Delaware corporation ("Landlord"),
and PHILADELPHIA CONSOLIDATED HOLDING CORP., a Pennsylvania corporation
("Tenant").

                                   BACKGROUND

         A. The Prudential Insurance Company of America ("Prudential") and
Tenant entered into a certain Lease, dated as of August, 1995 (the "Lease"),
pursuant to which Prudential leased to Tenant approximately 16,880 rentable
square feet of space on the first floor and 3,550 rentable square feet of space
on the lower level (the "Premises") of the building known as One Bala Plaza
("Building") and upon lands located in Bala Cynwyd, Lower Merion Township,
Montgomery County, Pennsylvania (the "Property"). The Premises are more fully
described in the Lease. Capitalized terms used but not defined herein shall have
the respective meanings ascribed to such terms in the Lease.

         B. Landlord heretofore succeeded to the right, title and interest of
Prudential in and to the Building and the Property, and all of Prudential's
right, title and interest as the "Landlord" under the Lease was assigned to
Landlord.

         C. Subject to the conditions set forth in this Amendment, Landlord and
Tenant desire to amend the Lease to, among other things, (i) expand the Premises
by adding thereto approximately 2,210 rentable square feet of space located on
the first floor of the Building, shown outlined and hatched in black on the
Floor plan attached hereto as Exhibit A (the "Additional Space"), (ii) provide
for the performance by Landlord of certain improvements to the Additional Space,
(iii) adjust the annual Base Rent payable by Tenant under the Lease, and (iv)
adjust Tenant's Percentage.

         NOW, THEREFORE, in consideration of the mutual covenants and conditions
herein set forth and for good and valuable consideration, the receipt and
sufficiency of which are hereby acknowledged, the parties hereto, intending to
be legally bound, hereby agree as follows:

         1. Demise of Additional Space. Landlord hereby leases, demises and
lets unto Tenant the Additional Space, and Tenant hereby takes and hires the
Additional Space from Landlord, for the period commencing on the later date
("Additional Space Commencement Date") to occur of (a) August 1, 1997 or (b)
the second business day after the date that the improvements to the Additional
Space to be made by Landlord pursuant to Section 3 of this Amendment are
Substantially Completed (defined below), and terminating on February 28, 2003,
being the scheduled expiration date of the term of the Lease. As used herein,
the term "Substantially Completed" shall mean (i) that state of completion which
will enable Tenant to
<PAGE>   2
reasonably utilize the Additional Space for the conduct of its ordinary
business, even though certain work remains to be completed by Landlord, without
unreasonable interruption or disruption of Tenant's business, and (ii) any
required approvals shall have been issued by the appropriate governmental
agencies.

         Landlord and Tenant agree that effective on the Additional Space
Commencement Date, the Additional Space shall be (A) added to the Premises,
which shall comprise an aggregate of approximately 22,640 rentable square feet,
and (B) governed by all of the provisions of the Lease, as amended hereby.

         2. Adjustment of Annual Base Rent and Additional Rent.

                  (a) Effective on the Additional Space Commencement Date and
continuing through the expiration date of the term of the Lease, Tenant shall
pay Landlord annual Base Rent and monthly installments thereof for the
Additional Space as follows:

<PAGE>   3
                  (b) Effective on the Additional Space Commencement Date and
continuing through the expiration date of the term of the Lease, Tenant shall
pay to Landlord additional rent with respect to the Additional Space, including
without limitation additional rent under Article 5 of the Lease. For that the
purpose, (i) the Base Year under paragraph 5(c)(i) of the Lease shall remain the
1995 calendar year through the expiration date of the term of the Lease, and
(ii) Tenant's Percentage under paragraph 5(c)(iii) shall be increased from
5.593% to 6.198% effective on the Additional Space Commencement Date and
continuing through the expiration date of the term of the Lease.

         Notwithstanding any provisions of this Amendment to the contrary, if
the improvements to the Additional Space to be made by Landlord pursuant to
Section 3 of this Amendment are not Substantially Completed by August 1, 1997
because of any action by Tenant including, but not limited to, the failure by
Tenant to deliver Tenant's Drawings (defined in Section 3 hereof) to Landlord on
or before May 15, 1997, Tenant's obligation to pay annual Base Rent and
additional rent (including, without limitation, additional rent under Article 5
of the Lease) with respect to the Additional Space (as detailed in this Section
2) shall begin to accrue on August 1, 1997 as if the delay had not occurred.

         3. Improvement of Additional Space. At Landlord's expense, up to a
maximum of $44,200.00 ("Landlord's Additional Space Improvement Allowance"),
Landlord shall construct and improve the Additional Space in Landlord's Building
standard manner, in accordance with (i) Tenant's interior design drawings
("Tenant's Drawings"), (ii) final plans and specifications for such construction
and improvement, to be prepared by Tenant's architect, McGillin Architecture
(the "Plans and Specifications"), and (iii) mechanical and engineering drawings
to be prepared based upon the Plans and Specifications, and at Landlord's
expense (as part of Landlord's Additional Space Improvement Allowance) and shall
be submitted to Landlord on or before May 15, 1997, time being of the essence.
Landlord's Additional Space Improvement Allowance shall cover all design and
construction costs and fees, including a 1.25% construction management fee,
labor and materials, construction permits and reasonable overhead (collectively
"Improvement Costs"). In the event the Improvement Costs of the design and
construction of the Additional Space exceeds Landlord's Additional Space
Improvement Allowance, then Tenant shall pay Landlord the entire amount of the
excess, in lump sum, within ten (10) days after Landlord's billing therefor,
together with an itemization of the Improvement Costs. Landlord and Tenant shall
each have the right to approve the final construction cost set forth in the
applicable construction contract(s) for the construction of the Additional
Space.

         Except for the improvements to the Additional Space to be made by
Landlord pursuant to this Section 3 of this Amendment, Tenant accepts the
Additional Space in their "AS IS" condition as of the date of this Amendment.
Tenant acknowledges that neither Landlord, nor Landlord's agents,
representatives, employees, servants or attorneys have made any representations
or promises, whether express or implied, concerning the condition of the
Additional Space, and agrees that Landlord shall have no obligation to make any
alterations or


                                        3
<PAGE>   4
improvements to the Additional Space for or during the remainder of the term of
the Lease, except for the improvements to be made by Landlord pursuant to this
Section 3.

         4. Conditions to Effectiveness. The Additional Space is currently
leased by Landlord to Ann Langer, Jennifer Lapin and Gary Lutzky, individuals
doing business as Global Vision (the "Current Tenant") under a lease (the
"Current Tenant Lease") that is scheduled to expire on May 2, 1999. Landlord is
currently negotiating a termination agreement with the Current Tenant pursuant
to which, among other things, the term of the Current Tenant Lease would be
terminated as soon as possible. Landlord and Tenant agree that notwithstanding
any provision of this Amendment to the contrary, all rights and obligations of
each of Tenant and Landlord under this Amendment are subject to the fulfillment
or satisfaction of each of the following conditions: (a) the execution and
delivery by Landlord and Current Tenant on or before September 1, 1997 of a
mutually acceptable agreement pursuant to which the term of the Current Tenant
Lease is terminated, and (b) the Current Tenant and all persons claiming any
rights by or through the Current Tenant shall have vacated and surrendered the

         (c) THIS PARAGRAPH 25(i) SETS FORTH WARRANTS OF ATTORNEY FOR AN

B.        The term "Accounting Period" means the actual time covered by each
          adjustment of commission.

C.        The term "losses incurred" means losses and loss adjustment expenses
          paid less salvages recovered during each Accounting Period, or part
          thereof, as respects losses which occurred during the Accounting
          Period, plus the reserve for losses outstanding at the end of the
          current period for which computation is being made. The reserve for
          losses outstanding at the end of each Accounting Period shall include
          a reserve for incurred but not reported losses.

D.        The phrase "reserve for incurred but not reported losses" as respects
          provisional calculations in each Accounting Period under this
          Agreement shall mean the total sum produced by multiplying the
          Premiums received by the Reinsurer, as determined under Article X -
          Reinsurance Premium of this Agreement, in each Accounting Period for
          which calculation is being made by the applicable percentages set
          forth in the table below:

                         6th and subsequent                   0%

E.        If for any Accounting Period, the total of Premiums received by the
          Reinsurer as shown under "INCOME" of the plan exceeds the total of the
          items shown under "OUTGO" of the plan, the Reinsurer shall pay to the
          Company 50.00% of the difference. If, for any Accounting Period, the
          total of the items shown under "OUTGO" of the plan exceeds the total
          of Premiums received by the Reinsurer as shown under "INCOME" of the
          plan, the difference shall be carried forward to the next Accounting
          Period's calculation of profit or loss as a deficit.

F.        The first calculation of profit or loss shall cover the Accounting
          Period beginning January 1997 and ending December 31, 1997. Each
          subsequent calculation shall cover an Accounting Period of one year,
          January 1 through December 31.

G.        Provisional computations of profit or loss shall be made by the
          Reinsurer within six months after the close of each Accounting Period.
          Subsequent calculations of profit or loss for each Accounting Period
          shall be made by the Reinsurer annually until all losses occurring
          during each Accounting Period have been finally settled.

H.        The Reinsurer, upon verification by the Company, shall promptly pay
          to the Company the amount of contingent commission, if any, shown in
          each provisional calculation and final calculation for each Accounting
          Period, less any contingent commission previously paid for the
          Accounting Period. If the contingent commission previously paid for
          the Accounting Period exceeds the amount of contingent commission, if
          any, shown in any calculation for the Accounting Period the Company
          shall promptly refund the difference to the Reinsurer.

I.        In case notice of termination of this Agreement shall be given by
          either party, calculations and adjustments of profit or loss shall
          continue to be made until the termination, expiration, or
          cancellation of all liability and the settlement of all losses covered
          under this Agreement.

J.        In the event this Agreement is terminated at a date other than the end
          of an Accounting Period, the fractional part of the last Accounting
          Period shall be combined with the previous Accounting Period and such
          combined period shall be considered one Accounting Period for which
          the calculations of profit or loss shall be made.


ARTICLE XII - REPORTS AND REMITTANCES

A.        The Company shall furnish the Reinsurer with all necessary data
          respecting premiums and losses for as long as one of the parties
          hereto has a claim against the other arising from this Agreement.

B.        Within 30 days after the close of each calendar quarter, the Company

C.        The Company shall have the responsibility to investigate, defend or
          negotiate settlements of all claims and lawsuits related to Policies
          written by the Company and reinsured under this Agreement. The
          Reinsurer, at its own expense, may associate with the Company in the
          defense or control of any claim, suit or other proceeding which
          involves or is likely to involve the reinsurance provided under this
          Agreement, and the Company shall cooperate in every respect in the
          defense of any such claim, suit or proceeding.


ARTICLE XIV - SALVAGE AND SUBROGATION

A.        In the event of the payment of any indemnity by the Reinsurer under
          this Agreement, the Reinsurer shall be subrogated, to the extent of
          such payment, to all of the rights of the Company against any person
          or entity legally responsible for damages of the loss. The Company
          agrees to enforce such rights; but, in case the Company refuses or
          neglects to do so, the Reinsurer is hereby authorized and empowered to
          bring any appropriate action in the name of the Company or their
          policyholders or otherwise to enforce such rights.

B.        From any amount recovered by subrogation, salvage or other means,
          there shall first be deducted the expenses incurred in effecting the
          recovery. The balance shall then be used to reimburse the excess
          carriers in the inverse order to that in which their respective
          liabilities attached, before being used to reimburse the Company for
          its primary loss.


ARTICLE XV - ACCESS TO RECORDS

The Reinsurer or its duly authorized representatives shall have the right to
examine, at the offices of the Company at a reasonable time, during the currency
of this Agreement or anytime thereafter, all books and records of the Company
relating to business which is the subject of this Agreement.

ARTICLE XVI - TAXES

The Company shall be liable for all taxes on premiums paid to the Reinsurer
under this Agreement, except income or profit taxes of the Reinsurer, and shall
indemnify and hold the Reinsurer harmless for any such taxes which the Reinsurer
may become obligated to pay to any local, state or federal taxing authority.


ARTICLE XVII - CURRENCY

Wherever the word "dollars" or the "$" symbol is used in this Agreement, it
shall mean dollars of the United States of America, excepting in those cases
where the Policy is issued by the Company in Canadian dollars, in which case it
shall mean dollars of Canada. In the event the Company is involved in a loss
requiring payment in United States and Canadian currency, the Company's
retention and the limit of liability of the Reinsurer shall be apportioned
between the two currencies in the same proportion as the amount of net loss in
each currency bears to the total amount of net loss paid by the Company. For the
purposes of this Agreement, where the Company receives premiums or pays losses
in currencies other than United States or Canadian currency, such premiums and
losses shall be converted into United States dollars at the actual rates of
exchange at which the premiums and losses are entered in the Company's books.


ARTICLE XVIII - OFFSET

Each party to this Agreement together with their successors or assigns shall
have and may exercise, at any time, the right to offset any balance or balances
due the other (or, if more than one, any other). Such offset may include
balances due under this Agreement and any other agreements heretofore or
hereafter entered into between the parties regardless of whether such balances
arise from premiums, losses or otherwise, and regardless of capacity of any
party, whether as assuming insurer and/or ceding insurer, under the various
agreements involved, provided however, that in the event of insolvency of a
party hereto, offsets shall only be allowed in accordance with the provisions of
Section 7427 of the Insurance Law of the State of New York to the extent such
statute or any other applicable law, statute or regulation governing such offset
shall apply.


ARTICLE IX - ERRORS OR OMISSIONS

Errors or omissions of a ministerial nature 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, addenda, or endorsements
attached hereto shall in no event exceed the limits specified herein nor be
extended to cover any risks, perils,

interpretation and application of this Agreement.

Part II - Mediation

If a dispute between the Company and the Reinsurer, arising out of the
provisions of this Agreement or concerning its interpretation or validity and
whether arising before or after termination of this Agreement has not been
settled through negotiation, both parties agree to try in good faith to settle
such dispute by nonbinding mediation, before resorting to arbitration.

Part III - Arbitration

A.        Resolution of Disputes - As a condition precedent to any right arising
          hereunder, any dispute not resolved by mediation between the Company
          and the Reinsurer arising out of the provisions of this Agreement or
          concerning its interpretation or validity, whether arising before or
          after termination of this Agreement, shall be submitted to arbitration
          in the manner hereinafter set forth.

B.        Composition of Panel - Unless the parties agree upon a single
          arbitrator within 15 days after the receipt of a notice of intention
          to arbitrate, all disputes shall be submitted to an arbitration panel
          composed of two arbitrators and an umpire chosen in accordance with
          Paragraph C. hereof.

C.        Appointment of Arbitrators - The members of the arbitration panel
          shall be chosen from persons knowledgeable in the insurance and
          reinsurance business. Unless a single arbitrator is agreed upon, the
          party requesting arbitration (hereinafter referred to as the
          "claimant") shall appoint an arbitrator and give written notice
          thereof by certified mail, to the other party (hereinafter referred to
          as the "respondent") together with its notice of intention to
          arbitrate. Within 30 days after receiving such notice, the respondent
          shall also appoint an arbitrator and notify the claimant thereof by
          certified mail. Before instituting a hearing, the two arbitrators so
          appointed shall choose an umpire. If, within 20 days after the
          appointment of the arbitrator chosen by the respondent, the two
          arbitrators fail to agree upon the appointment of an umpire, each of
          them shall nominate three individuals to serve as umpire, of whom the
          other shall decline two and the umpire shall be chosen from

          the remaining two by drawing lots. The name of the individual first
          drawn shall be the umpire.

D.        Failure of Party to Appoint an Arbitrator - If the respondent fails to
          appoint an arbitrator within 30 days after receiving a notice of
          intention to arbitrate, the claimant's arbitrator shall appoint an
          arbitrator on behalf of the respondent, such arbitrator shall then,
          together with the claimant's arbitrator, choose an umpire as provided
          in Paragraph C. of Part III of this Article.

E.        Involvement of Other Reinsurers - 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 Article and communications shall
          be made by the Company to each of the reinsurers constituting the one
          party; provided, however, nothing herein shall impair the right 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.

F.        If the Company is involved in a dispute under the terms of this
          Agreement and in one or more separate disputes with one or more other
          reinsurers in which common questions of law or fact are in issue, the
          Company or the Reinsurer, at its option, may join with such other
          reinsurers in a common arbitration proceeding under the terms of this
          Article. If the Company and such other reinsurers have commenced
          arbitration, the Reinsurer may at its option join such proceeding for
          the determination of the dispute between the Company and the
          Reinsurer.

G.        Submission of Dispute to Panel - Unless otherwise extended by the
          arbitration panel or agreed to by the parties, each party shall submit
          its case to the panel within 30 days after the selection of the
          umpire.

H.        Procedure Governing Arbitration - All proceedings before the panel
          shall be informal and the panel shall not be bound by the formal rules
          of evidence. The panel shall have the power to fix all procedural
          rules relating to the arbitration proceeding. In reaching any
          decision, the panel shall give due consideration to the customs and
          usages of the insurance and reinsurance business.

I.        Arbitration Award - The arbitration panel shall render its decision
          within 60 days after termination of the proceeding, which decision
          shall be in writing, stating the reasons therefor. The decision of the
          majority of the panel shall be final and binding on the parties to the
          proceeding.

J.        Cost of Arbitration - Unless otherwise allocated by the panel, each
          party shall bear the expense of its own arbitrator and shall jointly
          and equally bear with the other parties the expense of the umpire and
          the arbitration.

ARTICLE XXI - INSOLVENCY

A.        In the event of insolvency of the Company, the reinsurance provided by
          this Agreement shall be payable by the Reinsurer on the basis of the
          liability of the Company as respects Policies covered hereunder,
          without diminution because of such insolvency, directly to the Company
          or its liquidator, receiver, conservator or statutory successor except
          as provided in Sections 4118(a)(1)(A) and 1114(c) of the New York
          Insurance Law.

B.        The Reinsurer shall be given written notice of the pendency of each
          claim or loss which may involve the reinsurance provided by this
          Agreement within a reasonable time after such claim or loss is filed
          in the insolvency proceedings. The Reinsurer shall have the right to
          investigate each such claim or loss and interpose, at its own expense,
          in the proceedings where the claim or loss is to be adjudicated, any
          defense which it may deem available to the Company, its liquidator,
          receiver, conservator or statutory successor. The expense thus
          incurred by the Reinsurer shall be chargeable, subject to court
          approval, against the insolvent Company as part of the expense of
          liquidation to the extent of a proportionate share of the benefit
          which may accrue to the Company solely as a result of the defense
          undertaken by the Reinsurer.

C.        In addition to the offset provisions set forth in Article XVIII - 
          Offset, any debts or credits, liquidated or unliquidated, in favor of
          or against either party on the date of the receivership or liquidation
          order (except where the obligation was purchased by or transferred to
          be used as an offset) are deemed mutual debts or credits and shall be
          set off with the balance only to be allowed or paid. Although such
          claim on the part of either party against the other may be
          unliquidated or undetermined in amount on the date of the entry of the
          receivership or liquidation order, such claim will be regarded as
          being in existence as of such date and any claims then in existence
          and held by the other party may be offset against it.

D.        Nothing contained in this Article is intended to change the
          relationship or status of the parties to this Agreement or to enlarge
          upon the rights or obligations of either party hereunder except as
          provided herein.

ARTICLE  II - EFFECTIVE DATE AND TERMINATION

A.       This Agreement shall become effective with respect to losses occurring
         on and after 12:01 a.m., Eastern Standard Time, January 1, 1997, and
         shall remain in full force until terminated. This Agreement may be
         terminated at the close of any calendar year by either party giving to
         the other 90 days prior written notice by certified mail of its
         intention to do so.

B.       In the event of termination of this Agreement, the Company shall have
         the option of continuing or terminating the liability in force at the
         date of termination as set forth below. The Company may exercise such
         option provided written notice of the Company's election is given by
         certified mail to the Reinsurer prior to the date of termination.

         1.       All Policies covered hereunder and in force at the date of
                  termination of this Agreement shall continue until their
                  natural expiry, cancellation or next anniversary of such
                  business, whichever first occurs; but in no case shall this
                  reinsurance be extended for longer than one year, plus odd
                  time, after the termination date.

         2.       All reinsurance hereunder shall be automatically cancelled as
                  of the date of termination and the Reinsurer shall be released

                  the date of termination.

         liability, the Company and the Reinsurer shall renegotiate the terms
         and conditions relating to such option.

D.       If this Agreement shall terminate while a loss covered hereunder is in
         progress, it is agreed that, subject to the other conditions of this
         Agreement, the Reinsurer shall indemnify the Company as if the entire
         loss had occurred during the time this Agreement is in force provided
         the loss covered hereunder started before the date of termination.

ARTICLE III - TERRITORY

This Agreement applies to risks located in the United States of America, its
territories and possessions, and Canada, except that with respect to Inland
Marine and Multiple Peril Policies covered hereunder, the territorial limits of
this Agreement shall be those of the original Policies when such Policies are
written to cover risks primarily located in the United States of America, its
territories and possessions, and Canada.

ARTICLE IV - LIMIT AND RETENTION

A.       The limit and retention provided under this Agreement is set forth
         below:

         (i)      As respects one or more than one Line of Business covered
                  under this Agreement, the Company shall retain the first
                  $500,000 of Ultimate Net Loss as respects each risk in any one
                  Loss Occurrence. The Reinsurer shall then be liable for the
                  amount by which the Company's Ultimate Net Loss exceeds the
                  Company's retention of $500,000, but the liability of the
                  Reinsurer shall never exceed $1,500,000 each risk any one Loss
                  Occurrence, nor shall the Reinsurer's liability from all risks
                  in each Loss Occurrence exceed $3,500,000.

         (ii)     Notwithstanding the provisions set forth in Paragraph B. of
                  Article V - Ultimate Net Loss, the Reinsurer shall provide
                  coverage for 100% of losses arising out of Extra Contractual
                  Obligations as defined herein in addition to the Company's
                  retention and Reinsurer's limit of liability set for in (i)
                  above, subject to a maximum limit of liability of $4,500,000.

         (iii)    However, in the event an Ultimate Net Loss exceeds $500,000 as
                  respects each risk in any one Loss Occurrence, the liability
                  of the Reinsurer shall be increased to $1,700,000 each risk
                  any one Loss Occurrence and the retention of the Company shall
                  be reduced to $300,000 each risk any one Loss Occurrence as
                  respects subsequent losses resulting from that same Loss
                  Occurrence, however, in no event shall the Reinsurer's
                  liability from all risks in such Loss Occurrence exceed
                  $3,500,000.

B.       In the event of a loss involving a combination of the Property business
         subject to this agreement and Casualty business subject to the
         Company's Casualty Excess of Loss Reinsurance Agreement No.
         TC407A,B,C-R97, further reinsurance is provided when the Company's
         combined retention under these two referenced agreements, resulting
         from one occurrence, exceeds $500,000. In regard to such a combination
         loss, the Company will retain the first $500,000 of its combined
         retention each occurrence and the Reinsurer will reimburse the Company
         for the amount in excess of $500,000 subject to a


                                       3.

         maximum reimbursement under this provision of $2,000,000 for each
         occurrence. Such additional reinsurance will be pro-rated between this
         agreement and the Company's Casualty Excess of Loss Reinsurance
         Agreement No. TC407A,B,C-R97 in the amount that the Ultimate Net Loss
         under each agreement bears to the combined Ultimate Net Loss, subject
         to a maximum combined recovery of $2,000,000.

C.       Reinsurance of the Company's retention, set forth above, shall not be
         deducted in arriving at the Company's Ultimate Net Loss herein.

ARTICLE V - ULTIMATE NET LOSS

A.       The term "Ultimate Net Loss" shall mean the actual sum paid or to be
         paid by the Company in settlement of losses or liability after making
         deductions for all recoveries, including subrogation, salvages, and
         claims upon other reinsurances, whether collectible or not, which inure
         to the benefit of the Reinsurer under this Agreement, and shall include
         Allocated Loss Adjustment Expenses incurred by the Company.

B.       The term "Ultimate Net Loss" shall include 100% of Extra Contractual
         obligations, as defined herein, but only as respects business covered
         under this Agreement.

C.       The term "Ultimate Net Loss" shall also include "Ex-gratia Payments" as
         defined in Paragraph D. below, subject to the terms and conditions of
         this Agreement.

D.       The term "Ex-gratia Payments" shall mean payments made as an
         accommodation by the Company in settlement of a claim for which no
         coverage exists under the Policy reinsured hereunder, subject to the
         prior approval of the Reinsurer.

E.       The term "Allocated Loss Adjustment Expenses" shall mean all allocated
         expenses incurred by the Company in connection with the investigation,
         settlement, defense or litigation of any claim or loss covered by the
         Policies reinsured under this Agreement, and shall exclude the salaries
         of Company employees, office expenses or any other unallocated
         expenses.

F.       All recoveries, salvages or payments 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 to the loss settlement shall be made by the
         parties hereto.

G.       Nothing in this Article shall be construed to mean that losses are not
         recoverable hereunder until the Ultimate Net Loss of the Company has
         been ascertained.

ARTICLE VI - LOSS IN EXCESS OF POLICY LIMITS

A.       In the event the Company is liable to a policyholder as the result of a
         settlement or judgment rendered against the policyholder which is in
         excess of the Policy limit, 100% of that portion of the award made to
         the third party claimant which is in excess of the Company's Policy
         limit shall be added to the amount of the Company's Policy limit and
         the sum thereof shall be considered one loss, subject to the provision
         in Paragraph B. below and all other provisions set forth in this
         Agreement.

B.       With respect to coverage provided under this Article, recoveries from
         any insurance or reinsurance other than this Agreement, shall inure to
         the benefit of the Reinsurer and shall be deducted to arrive at the
         amount of the Company's Ultimate Net Loss.

ARTICLE VII - EXTRA CONTRACTUAL OBLIGATIONS

A.       "Extra Contractual Obligations" are defined as those liabilities not
         covered under any other provision of this Agreement and which arise
         from the handling of any claim on business covered 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, fraud or bad faith in rejecting an
         offer of settlement or in the preparation of the defense or in the
         trial of any action against its insured or reinsured or in the
         preparation or prosecution of an appeal consequent upon such action.

B.       The date on which an Extra Contractual Obligation is incurred by the
         Company shall be deemed, in all circumstances, to be the date of the
         original accident, casualty, disaster or loss occurrence.

C.       However, coverage hereunder as respects Extra Contractual Obligations
         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
         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.

D.       Extra Contractual Obligations shall not include loss arising out of
         engineering or other services or any other non-claims related activity
         provided to the insured by the Company.

E.       Recoveries, collectibles or retention from any other form of insurance
         or reinsurance including deductibles or self-insured retention which
         protect the Company against Extra Contractual Obligations shall inure
         to the benefit of the Reinsurer and shall be deducted from the total
         amount of Extra Contractual Obligations for purposes of determining the
         loss hereunder.

         the 168 hours provision.

         Expenses.

B.       The Company shall have the responsibility to investigate, defend or
         negotiate settlements of all claims and lawsuits related to Policies

         involves or is likely to involve the reinsurance provided under this
         Agreement, and the Company shall cooperate in every respect in the
         defense of any such claim, suit or proceeding.

ARTICLE XV - SALVAGE AND SUBROGATION

A.       In the event of the payment of any indemnity by the Reinsurer under
         this Agreement, the Reinsurer shall be subrogated, to the extent of
         such payment, to all of the rights of the Company against any person or
         entity legally responsible for damages of the loss. The Company agrees
         to enforce such rights; but, in case the Company refuses or neglects to
         do so, the Reinsurer is hereby authorized and empowered to bring any
         appropriate action in the name of the Company or their policyholders or
         otherwise to enforce such rights.

B.       From any amount recovered by subrogation, salvage or other means, there
         shall first be deducted the expenses incurred in effecting the
         recovery. The balance shall then be used to reimburse the excess
         carriers in the inverse order to that in which their respective
         liabilities attached, before being used to reimburse the Company for
         its primary loss.

ARTICLE XVI - ACCESS TO RECORDS

such taxes which the Reinsurer may become obligated to pay to any local, state
or federal taxing authority.

ARTICLE XVIII - CURRENCY

Wherever the word "dollars" or the "$" symbol is used in this Agreement, it
shall mean dollars of the United States of America, excepting in those cases
where the Policy is issued by the Company in Canadian dollars, in which case it
shall mean dollars of Canada. In the event the Company is involved in a loss
requiring payment in United States and Canadian currency, the Company's
retention and the limit of liability of the Reinsurer shall be apportioned
between the two currencies in the same proportion as the amount of net loss in
each currency bears to the total amount of net loss paid by the Company. For the
purposes of this Agreement, where the Company receives premiums or pays losses
in currencies other than United States or Canadian currency, such premiums and
losses shall be converted into United States dollars at the actual rates of
exchange at which the premiums and losses are entered in the Company's books.

ARTICLE XIX - OFFSET

Each party to this Agreement together with their successors or assigns shall
have and may exercise, at any time, the right to offset any balance or balances
due the other (or, if more than one, any other). Such offset may include
balances due under this Agreement and any other agreements heretofore or
hereafter entered into between the parties regardless of whether such balances
arise from premiums, losses or otherwise, and regardless of capacity of any
party, whether as assuming insurer and/or ceding insurer, under the various
agreements involved, provided however, that in the event of insolvency of a
party hereto, offsets shall only be allowed in accordance with the provisions of

ARTICLE XVIII - DISPUTE RESOLUTION

Part I - Choice Of Law And Forum

Any dispute arising under this Agreement shall be resolved in the State of
Pennsylvania, and the laws of the State of Pennsylvania, shall govern the
interpretation and application of this Agreement.

Part II - Mediation

If a dispute between the Company and the Reinsurer, arising out of the
provisions of this Agreement or concerning its interpretation or validity and
whether arising before or after termination of this Agreement has not been
settled through negotiation, both parties agree to try in good faith to settle
such dispute by non binding mediation, before resorting to arbitration.

Part III - Arbitration

A.       Resolution of Disputes - As a condition precedent to any right arising
         hereunder, any dispute not resolved by mediation between the Company
         and the Reinsurer arising out of the provisions of this Agreement or
         concerning its interpretation or validity, whether arising before or
         after termination of this Agreement, shall be submitted to arbitration
         in the manner hereinafter set forth.

B.       Composition of Panel - Unless the parties agree upon a single
         arbitrator within 15 days after the receipt of a notice of intention to
         arbitrate, all disputes shall be submitted to an arbitration panel
         composed of two arbitrators and an umpire chosen in accordance with
         Paragraph C. hereof.

C.       Appointment of Arbitrators - The members of the arbitration panel shall
         be chosen from persons knowledgeable in the insurance and reinsurance
         business. Unless a single arbitrator is agreed upon, the party
         requesting arbitration (hereinafter referred to as the "claimant")
         shall appoint an arbitrator and give written notice thereof by
         certified mail, to the other party (hereinafter referred to as the
         "respondent") together with his notice of intention to arbitrate.
         Within 30 days after receiving such notice, the respondent shall also
         appoint an arbitrator and notify the claimant thereof by certified
         mail. Before instituting a hearing, the two arbitrators so appointed
         shall choose an umpire. If, within 20 days after the appointment of the
         arbitrator chosen by the respondent, the two arbitrators fail to agree
         upon the appointment of an umpire, each of them shall nominate three
         individuals to serve as umpire, of whom the other shall decline two and
         the umpire shall be chosen from the remaining two by drawing lots. The
         name of the individual first drawn shall be the umpire.

D.       Failure of Party to Appoint an Arbitrator - If the respondent fails to
         appoint an arbitrator within 30 days after receiving a notice of
         intention to arbitrate, the claimant's arbitrator shall appoint an
         arbitrator on behalf of the respondent, such arbitrator shall then,
         together with the claimant's arbitrator, choose an umpire as provided
         in Paragraph C. of Part III of this Article.

E.       Involvement of Other Reinsurers - 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 Article and communications shall
         be made by the Company to each of the reinsurers constituting the one
         party; provided, however, nothing herein shall impair the right 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.

F.       If the Company is involved in a dispute under the terms of this
         Agreement and in one or more separate disputes with one or more other
         reinsurers in which common questions of law or fact are in issue, the
         Company or the Reinsurer, at its option, may join with such other
         reinsurers in a common arbitration proceeding under the terms of this
         Article. If the Company and such other reinsurers have commenced
         arbitration, the Reinsurer may at its option join such proceeding for
         the determination of the dispute between the Company and the Reinsurer.

G.       Submission of Dispute to Panel - Unless otherwise extended by the
         arbitration panel or agreed to by the parties, each party shall submit
         its case to the panel within 30 days after the selection of the umpire.

H.       Procedure Governing Arbitration - All proceedings before the panel
         shall be informal and the panel shall not be bound by the formal rules
         of evidence. The panel shall have the power to fix all procedural rules
         relating to the arbitration proceeding. In reaching any decision, the
         panel shall give due consideration to the customs and usages of the
         insurance and reinsurance business.

I.       Arbitration Award - The arbitration panel shall render its decision
         within 60 days after termination of the proceeding, which decision
         shall be in writing, stating the reasons therefor. The decision of the
         majority of the panel shall be final and binding on the parties to the
         proceeding.

J.       Cost of Arbitration - Unless otherwise allocated by the panel, each
         party shall bear the expense of its own arbitrator and shall jointly
         and equally bear with the other parties the expense of the umpire and
         the arbitration.

ARTICLE XXII - INSOLVENCY

A.       In the event of insolvency of the Company, the reinsurance provided by
         this Agreement shall be payable by the Reinsurer on the basis of the
         liability of the Company as respects Policies covered hereunder,
         without diminution because of such insolvency, directly to the Company
         or its liquidator, receiver, conservator or statutory successor except
         as provided in Sections 4118(a)(1)(A) and 1114(c) of the New York
         Insurance Law.

B.       The Reinsurer shall be given written notice of the pendency of each
         claim or loss which may involve the reinsurance provided by this
         Agreement within a reasonable time after such claim or loss is filed in
         the insolvency proceedings. The Reinsurer shall have the right to
         investigate each such claim or loss and interpose, at its own expense,
         in the proceedings where the claim or loss is to be adjudicated, any
         defense which it may deem available to the Company, its liquidator,
         receiver, conservator or statutory successor. The expense thus incurred
         by the Reinsurer shall be chargeable, subject to court approval,
         against the insolvent Company as part of the expense of liquidation to
         the extent of a proportionate share of the benefit which may accrue to
         the Company solely as a result of the defense undertaken by the
         Reinsurer.

C.       In addition to the offset provisions set forth in Article XVIII -
         Offset, any debts or credits, liquidated or unliquidated, in favor of
         or against either party on the date of the receivership or liquidation
         order (except where the obligation was purchased by or transferred to
         be used as an offset) are deemed mutual debts or credits and shall be
         set off with the balance only to be allowed or paid. Although such
         claim on the part of either party against the other may be unliquidated
         or undetermined in amount on the date of the entry of the receivership
         or liquidation order, such claim will be regarded as being in existence
         as of such date and any claims then in existence and held by the other
         party may be offset against it.

D.       Nothing contained in this Article is intended to change the
         relationship or status of the parties to this Agreement or to enlarge
         upon the rights or obligations of either party hereunder except as
         provided herein.

ARTICLE XXIII - SPECIAL TERMINATION

A.       Notwithstanding the termination provisions set forth in Article II -
         Effective Date and Termination, this Agreement may be:

                  a.       Entry of an order of liquidation, rehabilitation,
                           receivership or conservatorship with respect to the
                           Company or the Reinsurer by any court or regulatory
                           authority;

                  b.       Assignment of this Agreement by either party;

                  c.       Any transfer of control of either party by change in
                           ownership or otherwise;

                  d.       General reinsurance of any portion of the Company's
                           business it retains net for its own account, as
                           determined under the provisions of this Agreement

                  Paragraph, upon the discovery of the following event:

                           policyholders surplus during any calendar year. Such
                           reduction shall be determined by calculating the
                           difference between the Company's prior year annual
                           statement and each subsequent quarterly statutory
                           statement within such current calendar year.

                  As respects the event set forth in this Paragraph A.2., the
                  Company shall be obligated to notify the Reinsurer in writing
                  within 30 days after the filing of its quarterly statement.
                  Upon receipt of such notification the Reinsurer shall have the
                  right to terminate this Agreement, by giving not less than 30
                  days notice of its intention to do so.

B.       Any notice of termination pursuant to provisions set forth in Paragraph
         A.2. above shall be sent by certified mail, return receipt requested.
         Such notice period shall commence upon the other party's receipt of the
         notice of termination.

C.       In the event of termination, the Reinsurer shall not be liable for
         losses occurring subsequent to the date of termination.

ARTICLE XXIV - AMENDMENTS

This Agreement may be amended by mutual consent of the parties expressed in an
addendum; and such addendum, when executed by both parties, shall be deemed to
be an integral part of this Agreement and binding on the parties hereto.

         parties hereto.

may be submitted to the Reinsurer as Special Acceptances. Reporting of such
risks and premium, therefore, shall be subject to the terms, conditions or
limitations of this Agreement.


ARTICLE VII - BINDING METHOD AND DECLINATIONS

A.       The liability of the Reinsurer shall attach at the time the Company
         marks the reinsurance in its records. Each cession, after being bound,
         is to be reported to the Reinsurer on a monthly bordereau. If the
         reinsurance inception is prior to the date on which the cession is made
         (or revised), the cession must be made on the basis "Warranted No Known
         or Reported Losses" as of the date on which the cession was made. No
         cession shall be made when the inception of the "Reinsurance Term" is
         more than forty-five (45) days prior to the date on which the
         reinsurance is bound.

B.       If the reinsurance is unacceptable to the Reinsurer for any reason, the
         Reinsurer shall so notify the Company in writing of its declination
         within fifteen (15) days of the Reinsurer's receipt of the bordereau.
         The Company shall replace the reinsurance promptly, but within a period
         not to exceed thirty (30) days after receipt by the Company of the
         notice of declination from the Reinsurer, or as soon as practicable
         under applicable state regulation, but in no event to exceed sixty (60)
         days.


ARTICLE VIII - PREMIUM AND COMMISSIONS

The Company shall rate each submission to this Agreement in accordance with
either the Swiss Reinsurance America Corporation Electronic Rating software,
where applicable, or the hard copy Swiss Reinsurance America Corporation Rating
Scales, but in all cases in accordance with instructions provided by Swiss
Reinsurance America Corporation concerning the applicability of "Sprinklered" or
"Non-Sprinklered" scales. The Company shall deduct 30% commission allowance from
the calculated gross reinsurance premium to determine the excess premium for
each risk. However, in no case will the final rate for calculation of excess
premium be less than .04 gross of commission per $100 of exposure.

         1.       Monthly:

                  Monthly account current consisting of total written premiums,

                  The Company shall report all losses to the Reinsurer on an
                  individual case basis.


ARTICLE XI - LOSS PROCEDURE

A.       The Company shall promptly notify the Reinsurer of each claim which may
         involve the reinsurance provided hereunder and of all subsequent
         developments relating thereto, stating the amount claimed and estimate
         of the Company's Ultimate Net Loss and Allocated Loss Adjustment
         Expenses. Notwithstanding the provisions set forth in any other
         Article herein, prompt notification of loss shall be considered a
         condition precedent to liability under this Agreement.

B.       The Company shall have the responsibility to investigate, defend or
         negotiate settlements of all claims and lawsuits related to Policies
         written by the Company and reinsured under this Agreement. The
         Reinsurer, at its own expense, may associate with the Company in the
         defense or control of any claim, suit or other proceeding which
         involves or is likely to involve the reinsurance provided under this
         Agreement, and the Company shall cooperate in every respect in the
         defense of any such claim, suit or proceeding.

C.       Payment of Reinsurance Recoveries

         Recoveries under this Agreement shall be made on an individual case
         basis for all claims settlements and the Reinsurer will remit forthwith
         its share of any loss covered hereunder upon receipt of satisfactory
         evidence of such loss having been paid by the Company unless otherwise
         mutually agreed.


ARTICLE XII - SALVAGE AND SUBROGATION

A.       In the event of the payment of any indemnity by the Reinsurer under
         this Agreement, the Reinsurer shall be subrogated, to the extent of
         such payment, to all of the rights of the Company against any person or
         entity legally responsible for damages of the loss. The Company agrees
         to enforce such rights; but, in case the Company refuses or neglects to
         do so, the Reinsurer is hereby authorized and empowered to bring any
         appropriate action in the name of the Company or their policyholders or
         otherwise to enforce such rights.

B.       From any amount recovered by subrogation, salvage or other means, there
         shall first be deducted the expenses incurred in effecting the
         recovery. The balance shall then be used to reimburse the excess
         carriers in the inverse order to that in which their respective
         liabilities attached, before being used to reimburse the Company for
         its primary loss.

                  occurring subsequent to the termination of this Agreement.

         3.       If this Agreement shall terminate while a loss covered

                  indemnify the Company as if the entire loss had occurred
                  during the time this Agreement is in force provided the loss
                  covered hereunder started before the date of termination.

B.       Termination

         Notwithstanding any other provisions of this Agreement to the contrary,
         this Agreement shall automatically terminate upon the happening of the
         following events:

                  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

         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

         same tax twice.


ARTICLE XVII - INSOLVENCY

In the event of the insolvency of the Company, reinsurance under this Agreement
shall be payable by the Reinsurer on the basis of the liability of the Company
without diminution because of such insolvency, directly to the Company or its
liquidator, receiver or statutory successor. Nothing contained herein shall in
any manner create any obligations of the Reinsurer or establish any rights
against the Reinsurer in favor of the Company's policyholder or any other
person not party to the Agreement. The Reinsurer shall be given written notice
of the pendency of each claim which may involve the reinsurance afforded by this
Agreement within a reasonable time after such claim is filed in the insolvency
proceeding. The Reinsurer shall have the right to investigate each such claim
and interpose, at its own expense, in the proceeding where the claim is to be
adjudicated, any defense which it may deem available to the Company or its
liquidator, receiver or statutory successor. The expense thus incurred by the
Reinsurer shall be chargeable, subject to court approval, against the insolvent
Company as part of the expense of liquidation to the extent of a proportionate
share of the benefit which may accrue to the Company solely as a result of the
defense undertaken by the Reinsurer.


ARTICLE XVIII - ARBITRATION

Any dispute between the Company and the Reinsurer arising out of the provisions
of this Agreement or concerning its interpretation or validity shall be
submitted to arbitration. Any party may initiate arbitration by giving written
notice to the other party of its intention to arbitrate together with the name
of its selected arbitrator. Within thirty (30) days of receiving such notice,
the other party shall appoint an arbitrator. In the event that any party fails
to appoint an arbitrator within the time specified, the other party shall have
the right to appoint the said arbitrator forthwith. The two arbitrators named
shall select a third arbitrator. The arbitrators shall be officials or former
officials of insurance or reinsurance companies not under the control or
management of any party to this Agreement. The arbitrators shall not be bound
by judicial formalities or formal rules of evidence and shall give due
consideration to the customs and usage of the insurance and reinsurance
business. A majority decision in writing shall be final and binding. Unless
otherwise allocated by the

arbitrators, shall be borne equally by the parties.


ARTICLE XIX - ERRORS AND OMISSIONS

Errors or omissions made in connection with the reporting of any premium, or
with the reporting of any business reinsured hereunder, shall not relieve either
party from any liability which would have attached had such error or omission
not occurred, and provided such error or omission is rectified promptly upon
discovery.


ARTICLE XX - AMENDMENT PROVISIONS

This Agreement may, by mutual consent, be altered in any of its terms and
conditions by a signed addendum thereto.

regulatory authority for use in a policy that is subject to this Agreement or
where a pollution exclusion that has been used in a policy is overturned, either
in whole or in part, by a court having jurisdiction, there shall be no recovery

This Certificate is an Agreement of Facultative Reinsurance under which the
Reinsurer, in consideration of the payment of the reinsurance premium and
subject to the terms, conditions and limits stated herein, indemnifies the
Company with respect to its insurance liability for payments made by the
Company on the policy reinsured hereunder. In no event shall anyone other than
the Reinsurer, the Company, its or their receiver, liquidator or statutory
successor have any rights under this Certificate.

REINSURER'S OBLIGATION. The Reinsurer's obligation to indemnify the Company
shall follow the terms and conditions of this Certificate and of the Company's
policy furnished to the Reinsurer at the effective date of this Certificate,
unless otherwise specifically provided herein by endorsement made a part of this
Certificate. Any change in the terms and/or conditions of the policy
reinsured hereunder, subsequent to the effective date of the Certificate, shall
not increase or extend the Reinsurer's liability hereunder unless such change
is made a part of this Certificate by endorsement issued by the Reinsurer.

B. RETENTION OF THE COMPANY. This Certificate is issued in reliance of the
Company's not reducing its net interest in the policy reinsured hereunder as
determined by the amount specified in Item 3 (Company Retention). Should the
Company Retention be reduced by reinsurance or otherwise without notice to the
Reinsurer (except as the Company Retention may be covered by nonspecific excess
of loss catastrophe reinsurance applying to more than one of the Company's
policies in a single event) the Reinsurer shall in no event be liable for a
larger proportion of any loss otherwise fully collectible hereunder than the
percentage which the actual amount of the Company Retention at the time of loss
bears to the amount stipulated in Item 3; and there shall be no return premium
to the Company on account of any such reduction in the Reinsurer's liability
for loss.

C. COOPERATION OF THE COMPANY. The Company shall furnish the Reinsurer with a
copy of its policy reinsured hereunder and all endorsements thereto, which in
any manner affect this Certificate, and shall make available for inspection and
place at the disposal of the Reinsurer at reasonable times, at the office of
the Company during business hours, any of its records relating to this
reinsurance or claims in connection therewith.

D. NOTICE OF LOSS OR CLAIM. The Company shall give prompt written notice to the
Reinsurer (1) of any occurrence or claim in which the Company's estimate of the
value of injuries or damages sought, without regard to liability, might result
in a judgement in an amount sufficient to involve this Certificate; (2) if
this reinsurance is on an excess of loss basis, of any occurrence or claim in
which the Company has created a loss reserve equal to or greater than one-half
of the Company Retention stipulated in Item 3; (3) if this reinsurance is on a
pro rata basis, when notice of claim is received by the Company; and (4) all
material developments pertaining to any notice provided hereunder.

E. DEFENSE OF CLAIMS OR SUITS. The Company shall investigate and defend all
claims involving the reinsurance provided by this Certificate. While the
Reinsurer does not undertake to investigate or defend claims or suits, it shall
nevertheless have the right and be given the opportunity to associate with the
Company and its representatives at its own expense in the defense and control
of any claim, suit or proceeding involving this reinsurance with full
cooperation of the Company.

F. LOSS PAYABLE. The Reinsurer shall indemnify the Company for all losses paid
in accordance with the terms, conditions and limits of this Certificate and the
terms, conditions and limits of the policy reinsured hereunder. The Reinsurer
shall pay to the Company its proportion of such losses promptly following
receipt of satisfactory proof of loss in the following manner:

(1) If this reinsurance is on an excess of loss basis, the amount of the
Reinsurer's liability for loss hereunder shall be its indicated proportion of
the excess amount, if any, by which ultimate loss to the policy reinsured
hereunder exceeds the amount or amounts in excess of which this reinsurance
attaches, after first having deducted all recoveries from any source except
those from such portions of other excess of loss reinsurance which do not
overlap or duplicate this coverage.

(2) If this reinsurance is on a pro rata basis, the amount of the Reinsurer's
liability for each loss shall be in the proportion that the sum reinsured
hereunder bears to the total sum insured by the reinsured policy at the time
this Certificate becomes effective or at the time of loss, whichever proportion
is less (unless otherwise endorsed hereto).

In addition, the Reinsurer shall pay its proportion of expenses which are
within the terms of the policy reinsured hereunder (other than Company
salaries, travel and office expenses) and incurred by the Company in the
investigation and settlement of claims or suits as well as its proportion of
court costs and interest on that part of any judgment or settlement award fixing
the amount of the Company's insurance liability under the reinsured policy as
follows: (i) With respect to reinsurance provided on an excess of loss basis,
in the ratio that the Reinsurer's loss payment bears to the Company's gross
loss payment under the policy reinsured. In the event there is no loss payment
by the Reinsurer, there shall be no expense, court cost or interest payment.

(ii) With respect to reinsurance provided on a pro rata basis, in the ratio
that the Reinsurer's limit of liability bears to the Company's gross limit of
liability under the policy reinsured.

G. SALVAGE. The Reinsurer will be paid or credited by the Company with its
proportion of salvage, i.e. reimbursement obtained or recovery made by the
Company. If the reinsurance afforded by the Certificate is on an excess of loss
basis, salvage shall be applied in the inverse order in which liability
attaches. All costs (other than Company salaries, travel and office expenses) of
such salvage or reimbursement shall be borne by the Company and the Reinsurer in
proportion to the ultimate benefits accruing to each.

H. TAXES. The Company will be liable for all taxes (except income taxes) on
business ceded to the Reinsurer under this Certificate.

I. INSOLVENCY. In the event of the insolvency of the Company, reinsurance under
this Certificate shall be payable by the Reinsurer on the basis of the
liability of the Company without diminution because of such insolvency,
directly to the Company or its liquidator, receiver or statutory successor.
Nothing contained herein shall in any manner create any obligations of the
Reinsurer or establish any rights against the Reinsurer in favor of the
Company's policy holder or any other person not parties to the Certificate. The
Reinsurer shall be given written notice of the pendency of each claim which may
invoke the reinsurance afforded by this Certificate within a reasonable time
after such claim is filed in the insolvency proceeding. It shall have the right
to investigate each such claim and interpose, at its own expense, in the
proceedings where the claim is to be adjudicated, any defense which it may deem
available to the Company or its liquidator, receiver, or statutory successor.
The expense thus incurred by the Reinsurer shall be chargeable, subject to
court approval, against the insolvent Company as part of the expense of
liquidation to the extent of a proportionate share of the benefit which may
accrue to the Company solely as a result of the defense undertaken by the
Reinsurer.

J. ARBITRATION. Any dispute between the Company and the Reinsurer arising out
of the provisions of this Certificate or concerning its interpretation or
validity shall be submitted to arbitration. Any party may initiate arbitration
by giving written notice to the other party of its intention to arbitrate
together with the name of its selected arbitrator. Within 30 days of receiving
such notice the other party shall appoint an arbitrator. In the event that any
party fails to appoint an arbitrator within the time specified, the other party
shall have the right to appoint said arbitrator forthwith. The two arbitrators
named shall select a third arbitrator. The arbitrators shall be officials or
former officials of insurance or reinsurance companies not under the control or
management of any part of this Certificate. The arbitrators shall not be bound
by judicial formalities or formal rules of evidence and shall give due
consideration to the customs and usage of the insurance and reinsurance
business. A majority decision in writing shall be final and binding. Unless
otherwise allocated by the arbitrators, all costs of the arbitration
proceedings, including the fees of the arbitrators, shall be borne equally by
the parties.

K. CANCELLATION. Cancellation of the policy reinsured hereunder shall
constitute automatic cancellation of this Certificate. This Certificate may be
cancelled by either the Company or the Reinsurer by mailing written notice
stating when, not less than 30 days thereafter, such cancellation shall be
effective. Proof of mailing shall be deemed proof of notice. If the reinsured
policy is cancelled, the return premium hereunder shall be proportional to
the original premium returned by the Company, subject to the stipulated
Certificate minimum premium. If the Reinsurer cancels, the return premium shall
be on a pro rata basis with the Certificate minimum premium waived.

In Witness Whereof, the Reinsurer has caused the Certificate to be signed by
its Chairman at New York, N.Y. and countersigned by a duly authorized
representative of the Reinsurer.

This Certificate is an Agreement of Facultative Reinsurance under which the
Reinsurer, in consideration of the payment of the reinsurance premium and
subject to the terms, conditions and limits stated herein, indemnifies the
Company with respect to its insurance liability for payments made by the
Company on the policy reinsured hereunder. In no event shall anyone other than
the Reinsurer, the Company, its or their receiver, liquidator or statutory
successor have any rights under this Certificate.

A. REINSURER'S OBLIGATION.  The Reinsurer's obligation to indemnify the Company
shall follow the terms and conditions of this Certificate and of the Company's
policy furnished to the Reinsurer at the effective date of this Certificate,
unless otherwise specifically provided herein by endorsement made a part of this
Certificate. Any change in the terms and/or conditions of the policy reinsured
hereunder, subsequent to the effective date of the Certificate, shall not
increase or extend the Reinsurer's liability hereunder unless such change is 
made a part of this Certificate by endorsement issued by the Reinsurer.

B. RETENTION OF THE COMPANY.  This Certificate is issued in reliance of the
Company's not reducing its net interest in the policy reinsured hereunder as
determined by the amount specified in Item 3 (Company Retention). Should the
Company Retention be reduced by reinsurance or otherwise without notice to the
Reinsurer (except as the Company Retention may be covered by nonspecific excess
of loss catastrophe reinsurance applying to more than one of the Company's
policies in a single event) the Reinsurer shall in no event be liable for a
larger proportion of any loss otherwise fully collectible hereunder than the
percentage which the actual amount of the Company Retention at the time of loss
bears to the amount stipulated in Item 3; and there shall be no return premium
to the Company on account of any such reduction in the Reinsurer's liability
for loss.

C. COOPERATION OF THE COMPANY.  The Company shall furnish the Reinsurer with a
copy of its policy reinsured hereunder and all endorsements thereto, which in
any manner affect this Certificate, and shall make available for inspection and
place at the disposal of the Reinsurer at reasonable times, at the office of
the Company during business hours, any of its records relating to this
reinsurance or claims in connection therewith.

D. NOTICE OF LOSS OR CLAIM.  The Company shall give prompt written notice to
the Reinsurer (1) of any occurrence or claim in which the Company's estimate of
the value of injuries or damages sought, without regard to liability, might
result in a judgement in an amount sufficient to involve this Certificate; (2)
if this reinsurance is on an excess of loss basis, of any occurrence or claim
in which the Company has created a loss reserve equal to or greater than
one-half of the Company Retention stipulated in Item 3; (3) if this reinsurance
is on a pro rata basis, when notice of claim is received by the Company; and
(4) all material developments pertaining to any notice provided hereunder.

E. DEFENSE OF CLAIMS OR SUITS.  The Company shall investigate and defend all 
claims involving the reinsurance provided by this Certificate. While the
Reinsurer does not undertake to investigate or defend claims or suits, it shall
nevertheless have the right and be given the opportunity to associate with the
Company and its representatives at its own expense in the defense and control of
any claim, suit or proceeding involving this reinsurance with full cooperation
of the Company.

F. LOSS PAYABLE.  The Reinsurer shall indemnify the Company for all losses paid
in accordance with the terms, conditions and limits of this Certificate and the
terms, conditions and limits of the policy reinsured hereunder. The Reinsurer
shall pay to the Company its proportion of such losses promptly following
receipt of satisfactory proof of loss in the following manner:

(1) If this reinsurance is on an excess of loss basis, the amount of the
Reinsurer's liability for loss hereunder shall be its indicated proportion of
the excess amount, if any, by which ultimate loss to the policy reinsured
hereunder exceeds the amount or amounts in excess of which this reinsurance
attaches, after first having deducted all recoveries from any source except
those from such portions of other excess of loss reinsurance which do not
overlap or duplicate this coverage.

(2) If this reinsurance is on a pro rata basis, the amount of the Reinsurer's
liability for each loss shall be in the proportion that the sum reinsured
hereunder bears to the total sum insured by the reinsured policy at the time
this Certificate becomes effective or at the time of loss, whichever proportion
is less (unless otherwise endorsed hereto).

In addition, the Reinsurer shall pay its proportion of expenses which are
within the terms of the policy reinsured hereunder (other than Company
salaries, travel and office expenses) and incurred by the Company in the 
investigation and settlement of claims or suits as well as its proportion of
court costs and interest on that part of any judgment or settlement award
fixing the amount of the Company's insurance liability under the reinsured
policy as follows:

(i) With respect to reinsurance provided on an excess of loss basis, in the
ratio that the Reinsurer's loss payment bears to the Company's gross loss
payment under the policy reinsured. In the event there is no loss payment by the
Reinsurer, there shall be no expense, court cost or interest payment.

(ii) With respect to reinsurance provided on a pro rata basis, in the ratio
that the Reinsurer's limit of liability bears to the Company's gross limit of
liability under the policy reinsured.

G. SALVAGE.  The Reinsurer will be paid or credited by the Company with its
proportion of salvage, i.e. reimbursement obtained or recovery made by the
Company. If the reinsurance afforded by the Certificate is on an excess of loss
basis, salvage shall be applied in the inverse order in which liability
attaches. All costs (other than Company salaries, travel and office expenses)
of such salvage or reimbursement shall be borne by the Company and the
Reinsurer in proportion to the ultimate benefits accruing to each.

H. TAXES.  The Company will be liable for all taxes (except income taxes) on
business ceded to the Reinsurer under this Certificate.

I. INSOLVENCY.  In the event of the insolvency of the Company, reinsurance
under this Certificate shall be payable by the Reinsurer on the basis of the
liability of the Company without diminution because of such insolvency,
directly to the Company or its liquidator, receiver or statutory successor.
Nothing contained herein shall in any manner create any obligations of the
Reinsurer or establish any rights against the Reinsurer in favor of the
Company's policy holder or any other person not parties to the Certificate. The
Reinsurer shall be given written notice of the pendency of each claim which may
invoke the reinsurance afforded by this Certificate within a reasonable time
after such claim is filed in the insolvency proceeding. It shall have the right
to investigate each such claim and interpose, at its own expense, in the
proceedings where the claim is to be adjudicated, any defense which it may deem
available to the Company or its liquidator, receiver, or statutory successor.
The expense thus incurred by the Reinsurer shall be chargeable, subject to
court approval, against the insolvent Company as part of the expense of
liquidation to the extent of a proportionate share of the benefit which may
accrue to the Company solely as a result of the defense undertaken by the
Reinsurer.

J. ARBITRATION.  Any dispute between the Company and the Reinsurer arising out
of the provisions of this Certificate or concerning its interpretation or
validity shall be submitted to arbitration. Any party may initiate arbitration
by giving written notice to the other party of its intention to arbitrate
together with the name of its selected arbitrator. Within 30 days of receiving
such notice the other party shall appoint an arbitrator. In the event that any
party fails to appoint an arbitrator within the time specified, the other party
shall have the right to appoint said arbitrator forthwith. The two arbitrators
named shall select a third arbitrator. The arbitrators shall be officials or
former officials of insurance or reinsurance companies not under the control or
management of any part of this Certificate. The arbitrators shall not be bound
by judicial formalities or formal rules of evidence and shall give due
consideration to the customs and usage of the insurance and reinsurance
business. A majority decision in writing shall be final and binding. Unless
otherwise allocated by the arbitrators, all costs of the arbitration
proceedings, including the fees of the arbitrators, shall be borne equally by
the parties.

K. CANCELLATION.  Cancellation of the policy reinsured hereunder shall
constitute automatic cancellation of this Certificate. This Certificate may be
cancelled by either the Company or the Reinsurer by mailing written notice
stating when, not less than 30 days thereafter, such cancellation shall be
effective. Proof of mailing shall be deemed proof of notice. If the reinsured
policy is cancelled, the return premium hereunder shall be proportional to the
original premium returned by the Company, subject to the stipulated Certificate
minimum premium. If the Reinsurer cancels, the return premium shall be on a pro
rata basis with the Certificate minimum premium waived.

In Witness Whereof, the Reinsurer has caused the Certificate to be signed by
its Chairman at New York, N.Y. and countersigned by a duly authorized
representative of the Reinsurer.

                                    ARTICLE 7

DEFINITIONS

A.       The term "Ultimate Net Loss" as used in this Agreement shall mean the
         actual loss paid by the Company or for which the Company becomes liable
         to pay, such loss to include 100% of any Extra Contractual Obligation
         (and expense) as defined in the EXTRA CONTRACTUAL OBLIGATIONS ARTICLE,
         expenses of litigation and interest, and all other loss expense of the
         Company including subrogation, salvage, and recovery expenses (office
         expenses and salaries of officials and employees not classified as loss
         adjusters are not chargeable as expenses for purposes of this
         paragraph), but salvages and all recoveries, including recoveries under
         all reinsurances which inure to the benefit of this Agreement (whether
         recovered or not), shall be first deducted from such loss to arrive at
         the amount of liability attaching hereunder.

         All salvages, recoveries or payments recovered or received subsequent
         to loss settlement hereunder shall be applied as if recovered or
         received prior to the aforesaid settlement, and all necessary
         adjustments shall be made by the parties hereto.

         For purposes of this definition, the phrase "becomes liable to pay"
         shall mean the existence of a judgment which the Company does not
         intend to appeal, or a release has been obtained by the Company, or the
         Company has accepted a proof of loss.

         Nothing in this clause shall be construed to mean that losses are not
         recoverable hereunder until the Company's Ultimate Net Loss has been
         ascertained.

         For all purposes of this Agreement, a loss is deemed to occur on the
         expiration date of the lease.

B.       The term "Policy" as used in this Agreement shall mean any binder,
         policy, or contract of insurance or reinsurance issued, accepted or
         held covered provisionally or otherwise, by or on behalf of the
         Company. For purposes of this Agreement, "Policy" refers to coverage on
         an individual lease, rather than a master policy. Lease extensions are
         deemed to be part of the original Policy.

C.       The term "Gross Net Earned Premium Income" as used in this Agreement
         shall mean gross earned premium income on business the subject of this
         Agreement less earned premium income paid for reinsurances, recoveries
         under which would inure to the benefit of this Agreement.

                                    ARTICLE 8
NET RETAINED LINES


This Agreement applies only to that portion of any insurances or reinsurances
covered by this Agreement which the Company retains net for its own account, and
in calculating the amount of any loss hereunder and also in computing the amount
in excess of which this Agreement attaches, only loss or losses in respect of
that portion of any insurances or reinsurances which the Company retains net for
its own account shall be included, it being understood and agreed that 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 reinsurers, whether specific or general, any amounts

                                                                          Page 3
<PAGE>   8
which may have become due from them whether such inability arises from the
insolvency of such other reinsurers or otherwise.

                                    ARTICLE 9

CURRENCY

The currency to be used for all purposes of this Agreement shall be United
States of America currency.

                                   ARTICLE 10

LOSS FUNDING

With respect to losses, funding will be in accordance with the attached Loss
Funding Clause No. 1301.2.

                                   ARTICLE 11

TAXES

The Company will be liable for taxes (except Federal Excise Tax) on premiums
reported to the Reinsurer hereunder.

Federal Excise Tax applies only to those Reinsurers, excepting Underwriters at
Lloyd's, London and other Reinsurers exempt from the Federal Excise Tax, who are
domiciled outside the United States of America.

The Reinsurer has agreed to allow for the purpose of paying the Federal Excise
Tax 1% of the premium payable hereon to the extent such premium is subject to
Federal Excise Tax.

In the event of any return of premium becoming due hereunder, the Reinsurer will
deduct 1% from the amount of the return, and the Company or its agent should
take steps to recover the Tax from the U.S. Government.


                                   ARTICLE 12

NOTICE OF LOSS AND LOSS SETTLEMENTS

The Company will advise the Reinsurer promptly of all claims which in the
opinion of the Company may involve the Reinsurer and of all subsequent
developments on these claims which may materially affect the position of the
Reinsurer.

The Reinsurer agrees to abide by the loss settlements of the Company, provided
that retroactive extension of Policy terms or coverages made voluntarily by the
Company and not in response to court decisions (whether such court decision is
against the Company or other companies affording the same or similar coverages)
will not be covered under this Agreement.

                                                                          Page 4
<PAGE>   9
When so requested the Company will afford the Reinsurer an opportunity to be
associated with the Company, at the expense of the Reinsurer, in the defense of
any claim or suit or proceeding involving this reinsurance and the Company will
cooperate in every respect in the defense of such claim, suit or proceeding.

The Reinsurer will pay its share of loss settlements immediately upon receipt of
proof of loss from the Company.


                                   ARTICLE 13

EXTRA CONTRACTUAL OBLIGATIONS

This Agreement shall protect the Company, subject to the Reinsurer's limit of
liability appearing in the COVER ARTICLE of this Agreement, where the loss
includes any Extra Contractual Obligations as provided for in the definition of
Ultimate Net Loss. "Extra Contractual Obligations" are defined as those
liabilities not covered under any other provision of this Agreement and which
arise from handling of any claim on business covered 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,
fraud or bad faith 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.

The date on which any Extra Contractual Obligation is incurred by the Company
shall be deemed, in all circumstances, to be the date of the original loss.

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 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.

                                   ARTICLE 14

DELAY, OMISSION OR ERROR

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, providing such delay, omission or
error is rectified upon discovery.

                                   ARTICLE 15

INSPECTION

The Company shall place at the disposal of the Reinsurer at all reasonable
times, and the Reinsurer shall have the right to inspect, through its authorized
representatives, all books, records and papers of the Company in connection with
any reinsurance hereunder or claims in connection herewith.

                                                                          Page 5

                                   ARTICLE 16

ARBITRATION

Any irreconcilable dispute between the parties to this Agreement will be
arbitrated in Bala Cynwyd, Pennsylvania in accordance with the attached
Arbitration Clause No. 22-01.1.

                                   ARTICLE 17

SERVICE OF SUIT

The attached Service of Suit Clause No. 20-01.5 - U.S.A. will apply to this
Agreement.

                                   ARTICLE 18

INSOLVENCY

In the event of the insolvency of the Company, reinsurance under this Agreement
shall be payable by the Reinsurer on the basis of the liability of the Company
under Policy or Policies reinsured without diminution because of the insolvency
of the Company, to the Company or to its liquidator, receiver or statutory
successor, except as provided by Section 4118(a) of the New York Insurance Law
or except when the Agreement specifically provides another payee of such
reinsurance in the event of the insolvency of the Company and when the Reinsurer
with the consent of the direct insured or insureds has assumed such Policy
obligations of the Company as direct obligations of the Reinsurer to the payees
under such Policies and in substitution for the obligations of the Company to
such payees.

It is agreed, however, that the liquidator or receiver or statutory successor of
the insolvent Company shall give written notice to the Reinsurer of the pendency
of a claim against the insolvent Company on the Policy or Policies reinsured
within a reasonable time after such claim is filed in the insolvency proceeding
and that during the pendency of such claim, the Reinsurer may investigate such
claim and interpose, at its own expense, in the proceeding when such claim is to
be adjudicated, any defense or defenses which it may deem available to the
Company or its liquidator or receiver or statutory successor. The expense thus
incurred by the Reinsurer shall be chargeable, subject to court approval,
against the insolvent Company as part of the expense of liquidation to the
extent of a proportionate share of the benefit which may accrue to the Company
solely as a result of the defense undertaken by the Reinsurer.

When two or more reinsurers are involved in the same claim and a majority in
interest elect to interpose defense to such claim, the expense shall be
apportioned in accordance with the terms of this Agreement as though such
expense had been incurred by the insolvent Company.

Should the Company go into liquidation or should a receiver be appointed, the
Reinsurer shall be entitled to deduct from any sums which may be due or may
become due to the Company under this reinsurance Agreement any sums which are
due to the Reinsurer by the Company under this reinsurance Agreement and which
are payable at a fixed or stated date as well as any other sums due the
Reinsurer which are permitted to be offset under applicable law.

In the event of the insolvency of any company or companies included in the
designation of "Company," this clause will apply only to the insolvent company
or companies.

                                                                          Page 6

<PAGE>   22
                                  LOSS FUNDING

This clause is only applicable to those Reinsurers who cannot qualify for credit
by the State having jurisdiction over the Company's loss reserves.

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
department or set up on its books reserves for losses covered hereunder which it
shall be required to set up by law it will forward to the Reinsurer a statement
showing the proportion of such loss reserves which is applicable to them.

The Reinsurer hereby agrees that it will apply for and secure delivery to the
Company a clear irrevocable and unconditional Letter of Credit issued by a bank
chosen by the Reinsurer and acceptable to the appropriate insurance authorities,
in an amount equal to the Reinsurer's proportion of the loss reserves in respect
of known outstanding losses that have been reported to the Reinsurer and
allocated loss expenses relating thereto as shown in the statement prepared by
the Company. Under no circumstances shall any amount relating to reserves in
respect of losses or loss expenses Incurred But Not Reported be included in the
amount of the Letter of Credit.

The Letter of Credit shall be "Evergreen" and 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
prior to any expiration date, the bank shall notify the Company by certified or
registered mail that it elects not to consider the Letter of Credit extended for
any additional period.

The Company, or its successors in interest, undertakes to use and apply any
amounts which it may draw upon such Credit pursuant to the terms of the
Agreement under which the Letter of Credit is held, and for the following
purposes only:

      (a) To pay the Reinsurer's share or to reimburse the Company for the
          Reinsurer's share of any liability for loss reinsured by this
          Agreement, the payment of which has been agreed by the Reinsurer and
          which has not otherwise been paid.

      (b) To make refund of any sum which is in excess of the actual amount
          required to pay the Reinsurer's share of any liability reinsured by
          this Agreement.

      (c) In the event of expiration of the Letter of Credit as provided for
          above, to establish deposit of the Reinsurer's share of known and
          reported outstanding losses and allocated expenses relating thereto
          under this Agreement. Such cash deposit shall be held in an interest
          bearing account separate from the Company's other assets, and interest
          thereon shall accrue to the benefit of the Reinsurer. It is understood
          and agreed that this procedure will be implemented only in exceptional
          circumstances and that, if it is implemented, the Company will ensure
          that a rate of interest is obtained for the Reinsurers on such a
          deposit account that is at least equal to the rate which would be paid
          by Citibank N.A. in New York, and further that the Company will
          account to the Reinsurers on an annual basis for all interest accruing
          on the cash deposit account for the benefit of the Reinsurer.

The bank chosen for the issuance of the Letter of Credit 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.

At annual intervals, or more frequently as agreed but never more frequently than
semiannually, the Company shall prepare a specific statement, for the sole
purpose of amending the Letter of Credit, of the Reinsurer's share of known and
reported outstanding losses and allocated expenses relating thereto. If the
statement shows that the Reinsurer's share of such losses and allocated loss
expenses exceeds 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 of the Letter of Credit increasing the
amount of credit by the amount of such difference. If, however, the statement
shows that the Reinsurer's share of known and reported outstanding losses plus
allocated loss expenses relating thereto is 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.

NOTE: -- Wherever used herein the terms:

         "Company" shall be understood to mean "Company," "Reinsured,"
         "Reassured" or whatever other term is used in the attached reinsurance
         agreement to designate the reinsured company. "Agreement" shall be

                               ARBITRATION CLAUSE


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.

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.

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 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 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 45 days from appointment of
the umpire. The respondent shall submit its brief within 45 days thereafter and
the claimant may submit a reply brief within 30 days after filing of the
respondent's brief.

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 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.

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.

       "Reinsured," "Reassured" or whatever other term is used in the attached
       Agreement to designate the reinsured company. The term "Agreement" shall
       be understood to mean "Contract," "Policy" or whatever other term is used
       to designate the attached reinsurance document.

                                SERVICE OF SUIT

This Clause applies only to a reinsurer domiciled outside the United States of
America or should the Company be authorized to do business in the State of New
York, a reinsurer unauthorized in New York as respects suits instituted in New
York.

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 Clause constitutes or
should be understood to constitute a waiver of the Reinsurer's right 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 10019-6829 and
that in any suit instituted against the Reinsurer upon this Agreement, the
Reinsurer will abide by the final decision of such court or of any appellate
court in the event of an appeal.

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.

Further, pursuant to any statute of any state, territory or district of the
United States which makes provision therefor, 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, 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.

Note: - Wherever used herein the terms:

     "Company" shall be understood to mean "Company," "Reinsured," "Reassured"
     or whatever other term is used in the attached reinsurance Agreement to
     designate the reinsured company. "Agreement" shall be understood to mean

                  than where such physical damage loss could have been recovered
                  from a third party but for the insolvency of such third party.

<PAGE>   36
                                    ARTICLE 6

         March 31, June 30, September 30, and December 31, 1997.

B.       Within 90 days following the expiration of this Agreement, the Company
         will calculate a premium at a rate of 3.5% multiplied by the Company's
         Gross Net Earned Premium Income. Should the premium so calculated
         exceed the deposit premium paid in accordance with Paragraph A. above,
         the Company will immediately pay the Reinsurer the difference. Should
         the premium so calculated be less than the deposit premium, the
         Reinsurer will immediately pay the Company the difference.


                                    ARTICLE 7

REPORTS

                                    ARTICLE 8

DEFINITIONS

A.       The term "Ultimate Net Loss" as used in this Agreement shall mean the
         actual loss paid by the Company or for which the Company becomes liable
         to pay, such loss to include 100% of any Extra Contractual Obligation
         (and expense) as defined in the EXTRA CONTRACTUAL OBLIGATIONS ARTICLE,
         100% of any Excess of Policy Limit as defined in the EXCESS OF POLICY
         LIMITS ARTICLE, expenses of litigation and interest, claim-specific
         declaratory judgment expenses, and all other loss expense of the
         Company including subrogation, salvage, and recovery expenses (office
         expenses and salaries of officials and employees not classified as loss
         adjusters are not chargeable as expenses for purposes of this
         paragraph), but salvages and all recoveries, including recoveries under
         all reinsurances which inure to the benefit of this Agreement (whether
         recovered or not), shall be first deducted from such loss to arrive at
         the amount of liability attaching hereunder.

         The phrase "claim-specific declaratory judgment expenses," as used in
         this Agreement will mean all expenses incurred by the Company in
         connection with declaratory judgment actions brought to determine the
         Company's defense and/or indemnification obligations that are allocable
         to specific Policies and claims subject to this Agreement. Declaratory
         judgment expenses will be deemed to have been incurred by the Company
         on the date of the original loss (if any) giving rise to the
         declaratory judgment action.



                                                                          Page 3
<PAGE>   37
         All salvages, recoveries or payments recovered or received subsequent
         to loss settlements hereunder shall be applied as if recovered or
         received prior to the aforesaid settlement, and all necessary
         adjustments shall be made by the parties hereto.

         For purposes of this definition, the phrase "becomes liable to pay"
         shall mean the existence of a judgment which the Company does not
         intend to appeal, or a release has been obtained by the Company, or the
         Company has accepted a proof of loss.

in excess of which this Agreement attaches, only loss or losses in respect of
that portion of any insurances or reinsurances which the Company retains net for
its own account shall be included, it being understood and agreed that 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 reinsurers, whether specific or general, any amounts which may
have become due from them whether such inability arises from the insolvency of
such other reinsurers or otherwise.


                                   ARTICLE 10

CURRENCY

TAXES

The Company will be liable for taxes (except Federal Excise Tax) on premiums
reported to the Reinsurer hereunder.

Federal Excise Tax applies only to those Reinsurers, excepting Underwriters at
Lloyd's, London and other Reinsurers exempt from the Federal Excise Tax, who are
domiciled outside the United States of America.

The Reinsurer has agreed to allow for the purpose of paying the Federal Excise
Tax 1% of the premium payable hereon to the extent such premium is subject to
Federal Excise Tax.

In the event of any return of premium becoming due hereunder, the Reinsurer will
deduct 1% from the amount of the return, and the Company or its agent should
take steps to recover the Tax from the U.S. Government.


                                   ARTICLE 13

NOTICE OF LOSS AND LOSS SETTLEMENTS

The Company will advise the Reinsurer promptly of all claims which in the
opinion of the Company may involve the Reinsurer and of all subsequent
developments on these claims which may materially affect the position of the
Reinsurer, such advices to include any claim for which the reserve is 50% or
more of the Company's retention.

The Reinsurer agrees to abide by the loss settlements of the Company, provided
that retroactive extension of Policy terms or coverages made voluntarily by the
Company and not in response to court decisions (whether such court decision is
against the Company or other companies affording the same or similar coverages)
will not be covered under this Agreement.

When so requested the Company will afford the Reinsurer an opportunity to be
associated with the Company, at the expense of the Reinsurer, in the defense of
any claim or suit or proceeding involving this reinsurance and the Company will
cooperate in every respect in the defense of such claim, suit or proceeding.

The Reinsurer will pay its share of loss settlements immediately upon receipt of
proof of loss from the Company.


                                   ARTICLE 14

EXCESS OF POLICY LIMITS

In the event the Ultimate Net Loss includes an amount in excess of the Company's
Policy limit, such amount, as provided for in the definition of Ultimate Net
Loss, in excess of the Company's Policy limit shall be added to the amount of
the Company's Policy limit, and the sum thereof shall be covered hereunder,
subject to the Reinsurer's limit of liability appearing in the COVER ARTICLE of
this Agreement.


                                                                          Page 5
<PAGE>   39

the fraud of a member of the Board of Directors or a corporate officer of the
Company 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.

For the purpose of this Article, the word "loss" shall mean any amounts for
which the Company would have been contractually liable to pay had it not been
for the limit of the original Policy.


                                   ARTICLE 15

EXTRA CONTRACTUAL OBLIGATIONS

This Agreement shall protect the Company, subject to the Reinsurer's limit of
liability appearing in the COVER ARTICLE of this Agreement, where the loss
includes any Extra Contractual Obligations as provided for in the definition of
Ultimate Net Loss. "Extra Contractual Obligations" are defined as those
liabilities not covered under any other provision of this Agreement and which
arise from handling of any claim on business covered 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,
fraud or bad faith 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.

The date on which any Extra Contractual Obligation is incurred by the Company
shall be deemed, in all circumstances, to be the date of the original loss.

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 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.


                                   ARTICLE 16

DELAY, OMISSION OR ERROR

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, providing such delay, omission
or error is rectified upon discovery.


                                   ARTICLE 17

INSPECTION

The Company shall place at the disposal of the Reinsurer at all reasonable
times, and the Reinsurer shall have the right to inspect, through its authorized
representatives, all books, records and papers of the Company in connection with
any reinsurance hereunder or claims in connection herewith.



                                                                        Page 6

Agreement.


                                   ARTICLE 20

INSOLVENCY

In the event of the insolvency of the Company, reinsurance under this Agreement
shall be payable by the Reinsurer on the basis of the liability of the Company
under Policy or Policies reinsured without diminution because of the insolvency
of the Company, to the Company or to its liquidator, receiver or statutory
successor, except as provided by Section 4118(a) of the New York Insurance Law
or except when the Agreement specifically provides another payee of such
reinsurance in the event of the insolvency of the Company and when the Reinsurer
with the consent of the direct insured or insureds has assumed such Policy
obligations of the Company as direct obligations of the Reinsurer to the payees
under such Policies and in substitution for the obligations of the Company to
such payees.

It is agreed, however, that the liquidator or receiver or statutory successor of
the insolvent Company shall give written notice to the Reinsurer of the pendency
of a claim against the insolvent Company on the Policy or Policies reinsured
within a reasonable time after such claim is filed in the insolvency proceeding
and that during the pendency of such claim, the Reinsurer may investigate such
claim and interpose, at its own expense, in the proceeding when such claim is to
be adjudicated, any defense or defenses which it may deem available to the
Company or its liquidator or receiver or statutory successor. The expense thus
incurred by the Reinsurer shall be chargeable, subject to court approval,
against the insolvent Company as part of the expense of liquidation to the
extent of a proportionate share of the benefit which may accrue to the Company
solely as a result of the defense undertaken by the Reinsurer.

When two or more reinsurers are involved in the same claim and a majority in
interest elect to interpose defense to such claim, the expense shall be
apportioned in accordance with the terms of this Agreement as though such
expense had been incurred by the insolvent Company.

Should the Company go into liquidation or should a receiver be appointed, the
Reinsurer shall be entitled to deduct from any sums which may be due or may
become due to the Company under this reinsurance Agreement any sums which are
due to the Reinsurer by the Company under this reinsurance Agreement and which
are payable at a fixed or stated date as well as any other sums due the
Reinsurer which are permitted to be offset under applicable law.

In the event of the insolvency of any company or companies included in the
designation of "Company," this clause will apply only to the insolvent company
or companies.


                                                                          Page 7

                                  LOSS FUNDING

This clause is only applicable to those Reinsurers who cannot qualify for
credit by the State having jurisdiction over the Company's loss reserves.

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
department or set up on its books reserves for losses covered hereunder which
it shall be required to set up by law it will forward to the Reinsurer a
statement showing the proportion of such loss reserves which is applicable to
them.

The Reinsurer hereby agrees that it will apply for and secure delivery to the
Company a clean irrevocable and unconditional Letter of Credit issued by a bank
chosen by the Reinsurer and acceptable to the appropriate insurance
authorities, in an amount equal to the Reinsurer's proportion of the loss
reserves in respect of known outstanding losses that have been reported to the
Reinsurer, allocated loss expenses relating thereto and Incurred But Not
Reported loss and loss expense as shown in the statement prepared by the
Company.

The Letter of Credit shall be "Evergreen" and 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 prior to any expiration date, the bank shall notify the Company by
certified or registered mail that it elects not to consider the Letter of
Credit extended for any additional period.

The Company, or its successors in interest, undertakes to use and apply any
amounts which it may draw upon such Credit pursuant to the terms of the
Agreement under which the Letter of Credit is held, and for the following
purposes only:

     (a)  To pay the Reinsurer's share or to reimburse the Company for the
          Reinsurer's share of any liability for loss reinsured by this
          Agreement, the payment of which has been agreed by the Reinsurer and
          which has not otherwise been paid.

     (b)  To make refund of any sum which is in excess of the actual amount
          required to pay the Reinsurer's share of any liability reinsured
          by this Agreement.

     (c)  In the event of expiration of the Letter of Credit as provided for
          above, to establish deposit of the Reinsurer's share of known and
          reported outstanding losses and allocated expenses relating thereto,
          and Incurred But Not Reported loss and loss expense, under this
          Agreement. Such cash deposit shall be held in an interest bearing
          account separate from the Company's other assets, and interest
          thereon shall accrue to the benefit of the Reinsurer. It is understood
          and agreed that this procedure will be implemented only in exceptional
          circumstances and that, if it is implemented, the Company will ensure
          that a rate of interest is obtained for the Reinsurers on such a
          deposit account that is at least equal to the rate which would be
          paid by Citibank N.A. in New York, and further that the Company will
          account to the Reinsurers on an annual basis for all interest accruing
          on the cash deposit account for the benefit of the Reinsurer.

The bank chosen for the issuance of the Letter of Credit 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.

At annual intervals, or more frequently as agreed but never more frequently
than semiannually, the Company shall prepare a specific statement, for the sole
purpose of amending the Letter of Credit, of the Reinsurer's share of known and
reported outstanding losses and allocated expenses relating thereto. If the
statement shows that the Reinsurer's share of such losses and allocated loss
expenses, and Incurred But Not Reported loss and loss expense, exceeds 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 of the Letter of Credit increasing the amount of credit
by the amount of such difference. If, however, the statement shows that the
Reinsurer's share of known and reported outstanding losses plus allocated loss
expenses, and Incurred But Not Reported loss and loss expense, relating thereto
is 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.

following strict rules of evidence but in which cross-examination and rebuttal
shall be allowed. The board shall make its decision within 60 days following the
termination of the hearing 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
