PART I

ITEM 1. BUSINESS


GENERAL

     The Navigators Group, Inc. (the "Group") is a holding company with 15
wholly owned subsidiaries.  Unless the context otherwise requires, the term
"Company" as used herein means the Group and its subsidiaries.

     Two of the Company's subsidiaries are insurance companies: Navigators
Insurance Company and NIC Insurance Company.  Navigators Insurance Company is
the Company's largest insurance company subsidiary and has been active since
1983.  It specializes principally in underwriting marine, aviation, property
(primarily inland marine) insurance and certain lines of specialty reinsurance
and non-marine insurance.  NIC Insurance Company is a wholly owned subsidiary
of Navigators Insurance Company, was licensed in 1989 and began operations in
1990.  It underwrites a small book of surplus lines property insurance in
certain states and, pursuant to an intercompany reinsurance pooling agreement,
cedes 100% of its gross direct writings from this business to Navigators
Insurance Company in exchange for assuming 10% of the total retained business
of Navigators Insurance Company.  Navigators Insurance Company and NIC
Insurance Company are collectively referred to herein as "Navigators".

     Another subsidiary, Navigators Corporate Underwriters Limited ("NCUL"),
which was formed in the fourth quarter of 1996, is admitted to underwrite
marine and related lines of business at Lloyd's of London as a corporate member
with limited liability, commencing with the 1997 year of account.

     Nine of the Company's subsidiaries are a group of underwriting management
companies: Somerset Marine, Inc., Somerset of Georgia, Inc., Somerset Insurance
Services of Texas, Inc., Somerset Insurance Services of California, Inc.,
Somerset Insurance Services of Washington, Inc., Somerset Re Management, Inc.,
Somerset Marine (UK) Limited ("Somerset (UK)"), Somerset Asia Pacific Pty
Limited ("Somerset Asia") and Navigators Management Corporation ("NMC")
(collectively, the "Somerset Companies").  The Somerset Companies produce,
manage and underwrite insurance and reinsurance for Navigators and ten other
unrelated insurance companies.

     Somerset Asia, a wholly-owned subsidiary, was created in the third quarter
of 1996 and will operate from an office in Sydney, Australia.  This office will
concentrate on marine, energy and construction business primarily in Indonesia,
Thailand, Malaysia, China and Vietnam.  The Australia office began writing
business in early 1997.

     Somerset (UK) Limited, formed in the fourth quarter of 1996, will serve as
an agency office for Navigators and ten other unrelated insurance companies and
will concentrate on business segments within marine, aviation, energy and
construction business.  Navigators expects to be authorized to operate a U.K.
branch in mid 1997.

     The other subsidiaries of the Company are Somerset Casualty Agency, Inc.,
Somerset Property, Inc. and Somerset Marine Aviation Property Managers, Inc.,
which are either inactive or in runoff.

     The Somerset Companies other then "Somerset (UK) and Somerset Asia (the
"Acquired Somerset Companies") were acquired by the Company in 1994 pursuant to
mergers (the "Mergers") that were approved by the stockholders of the Company
at a special meeting held June 30, 1994.  The Company accounted for the
transfer of the Acquired Somerset Companies' assets and liabilities at
historical cost under a method of accounting similar to "a pooling of
interests" and, accordingly, has reported results of operations as if the
Company and the Acquired Somerset Companies had been combined since inception.

     The Company's revenue is primarily comprised of premiums, commissions and
investment income.  Navigators derives substantially all of its business from
the Somerset Companies through either business written specifically for
Navigators or direct participation in, or by reinsuring certain 

                                     1

members of, insurance pools managed by the Somerset Companies.  The insurance
business and operations of Navigators are managed by NMC which is being merged
into Somerset Marine, Inc. in 1997 with Somerset Marine, Inc. as the surviving
company.

     The Somerset Companies specialize principally in the following lines of
business: marine, aviation, property (primarily inland marine) insurance and
certain lines of specialty reinsurance and non-marine
insurance.  In 1996 the Somerset Companies underwrote the marine business
through a syndicate of insurance companies, Navigators having the largest
participation in the syndicate.  They derive their revenue from commissions,
investment income, service fees and cost reimbursement arrangements from
Navigators and other insurers.  Commissions are earned both on a fixed
percentage of premiums and on underwriting profits on business placed with the
participating insurance companies within the syndicate.  Property and casualty
insurance premiums are cyclical in nature and, accordingly, during a "hard
market" demand for property and casualty insurance exceeds supply, or capacity,
and as a result, premiums and commissions may increase.  On the downturn of the
property and casualty cycle, supply exceeds demand, and as a result, premiums
and commissions may decrease.

     Navigators and the Somerset Companies earn investment income on cash
balances and invested assets.  The Somerset Companies also earn investment
income on fiduciary funds.  Such fiduciary funds are invested, subject to
applicable insurance regulations, primarily in short-term instruments.

     In addition to its wholly-owned subsidiaries, as of December 31, 1995 the
Company had a 21% ownership interest in Riverside Underwriters plc (formerly
known as Navigators Underwriters plc) ("Riverside").  This ownership interest
increased to 27% as of January 1, 1996 and had decreased to approximately 8% at
December 31, 1996.  Riverside, a U.K. corporation, owns 100% of Riverside
Corporate Underwriters Limited, a U.K. corporation, which has been admitted to
underwrite at Lloyd's of London as a corporate name with limited liability.
The transaction to reduce the Company's ownership in Riverside did not produce
a material capital gain or loss.  The Company will, however, remain entitled to
receive from Riverside an amount equal to the aggregate dividends that it would
have received if it had continued to hold its original investment to the extent
such dividends are attributable to writings at Lloyd's by Riverside Corporate
Underwriters Limited during the 1994, 1995 and 1996 years of account.  In
connection with the reduction of the Company's investment, NMC will no longer
be manager of Riverside and Riverside Corporate Underwriters Limited, although
NMC will remain entitled to profit commissions with respect to the 1994, 1995
and 1996 years of account.

     The Group, a Delaware corporation, was incorporated in November, 1982.
Navigators Insurance Company and NIC Insurance Company were incorporated in New
York in July, 1981, and December, 1988, respectively.  The Group directly owns
100% of Navigators Insurance Company, which in turn directly owns 100% of NIC
Insurance Company.

LINES OF BUSINESS

     Navigators underwrites principally marine, aviation, property (primarily
inland marine) insurance and certain lines of specialty reinsurance and
non-marine insurance.  As underwritten by Navigators, marine insurance includes
hull, energy, liability and cargo; aviation insurance includes hull and
liability on commercial aircraft and on aircraft manufactures; property
insurance includes primarily inland marine at present, but prior to 1995
primarily included large commercial and industrial "all risk" coverages;
reinsurance includes property and casualty assumed business which has been in
runoff since December 31, 1995 with only a few specialty treaties renewed in
1996; and non-marine insurance includes non-marine program business developed
to augment Navigators' reinsurance book.  In 1996, Navigators began to
underwrite onshore energy primarily covering property damage and machinery
breakdown.  See the table set forth in "Management's Discussion and Analysis -
Results of Operations - Revenues" for Navigators' gross written premium by line
of business and net written premium in the aggregate for the periods indicated.

MARINE INSURANCE

     Navigators obtains its marine business through its direct participation in
the pool managed by certain Somerset Companies and through its reinsurance of
one or more members of this pool.  The composition of the pool and the level of
participation of each member changes from time to time.

     As of December 31, 1996, members of the marine pool consisted, in addition
to Navigators, of Christiania General Insurance Corporation of New York,
Colonia Insurance Company, Employers Mutual Casualty Co., Farmers Mutual Hail
Insurance Company of Iowa, Harleysville Mutual Insurance Company, National
Liability and Fire Insurance Co., Pennsylvania Lumbermens Mutual Insurance
Company, Insurance Corporation of New York, Worcester Insurance Company and
Sorema North America Reinsurance Company as participants.  Navigators' net
participation in the marine pool was approximately 41% in 1996, 42% in 1995 and
48% in 1994.

     The Somerset Companies in 1996, 1995 and 1994 received commissions equal
to 7.5% of the gross premium earned on marine insurance.  They also are
entitled to receive a 20% contingent commission on net underwriting profits.

AVIATION INSURANCE

     Since October 1, 1995, Navigators writes 100% of the aviation business
produced by the Somerset Companies.  Through September 30, 1995, Navigators
received its aviation business both as a direct participant, and as a reinsurer
of the same pool members as participate in the marine pool.  Navigators' net
share of the aviation pool was approximately 56% for the first nine months of
1995 and 48% in 1994.  The aviation pool is managed by one of the Somerset
Companies, which received commissions equal to 7.5% of the gross earned
premiums, and is entitled to receive a 20% contingent commission on net
underwriting profits.

PROPERTY AND INLAND MARINE INSURANCE

     In 1996, Navigators wrote 100% of the property business (primarily inland
marine) produced by the Somerset Companies.  In 1995, Navigators received its
property insurance through direct participation in a pool managed by certain
Somerset Companies.  Navigators' participation in the pool was 85% in 1995 and
1994.  The remaining 15% was written by an unaffiliated insurance company.
This business consists primarily of inland marine risks, although prior to 1995
this business consisted primarily of large commercial and industrial property
risks.  The Somerset Companies in 1995 and 1994 received commissions on
property insurance equal to 10% of gross earned premiums and were entitled to
receive a 20% contingent commission on net underwriting profits.  The Somerset
Companies received commissions on inland marine insurance equal to 7.5% in 1996
and 1995 and 10% in 1994, of gross earned premiums and were entitled to receive
a 20% commission on net underwriting profits.  In late 1994, Navigators decided
to cease writing large commercial and industrial property risks and therefore
written premium volume in this line in 1995 and 1996 was significantly less
than in 1994.

ONSHORE ENERGY

     In 1996, Navigators began to underwrite onshore energy business which
principally focuses on the oil and gas, chemical and petrochemical, and power
generation industries with coverages primarily for property damage and
machinery breakdown.

SPECIALTY REINSURANCE AND NON-MARINE INSURANCE

     Navigators receives its reinsurance business through direct participation
in a book of business managed by one of the Somerset Companies.  Navigators'
participation in this business was 100% in 1996 and 1995, and 95% in 1994.  The
remaining 5% in 1994 was written by an unaffiliated insurance company.  This
reinsurance premium consists primarily of excess of loss and quota share
property, surety, and other specialty reinsurance lines.  The managing company
in 1996, 1995, and 1994 received commissions of 7.5% of gross earned premium
and was entitled to a contingent commission of 20% of net underwriting profits.
During 1995 Navigators began writing 100% of a book of non-marine program
business managed by the same Somerset Company.

REINSURANCE CEDED

     Navigators utilizes reinsurance principally to reduce its net liability on
individual risks, to protect against catastrophic losses, to maintain desired
ratios of net premiums written to statutory surplus and to stabilize loss
ratios.

     The ceding of reinsurance does not discharge the original insurer from its
primary liability to the policyholder.  The ceding company is required to pay
the losses even if the assuming company fails to meet its obligations under the
reinsurance agreement.

     Reinsurance is generally written under treaty contracts in which coverage
is either on a proportional basis, where the reinsurer shares proportionately
in premiums and losses, or on an excess of loss basis, where only losses above
a fixed point are reinsured.

     Navigators, both directly and through the syndicates in which it
participates, is protected by various treaty and facultative reinsurance
agreements.  Navigators diversifies its reinsurance by reinsuring with a number
of different reinsurers, principally in the United States and European
reinsurance markets.  This coverage is placed on behalf of Navigators by a
number of different reinsurance intermediaries, each of which is employed
because of its expertise in placing a particular type of coverage.  All such
intermediaries are compensated by the reinsurers.

     Navigators' reinsurance security committee continually monitors the
financial strength of its reinsurers and the amounts of reinsurance receivables
from those reinsurers.  To the extent that it is determined that the ultimate
amount collectible is less than the amount recorded on a receivable, a reserve
is established.  At each of December 31, 1996 and 1995, the Company had an
allowance for uncollectible reinsurance of $800,000.

RESERVES

     Insurance companies are required to maintain reserves for unpaid losses
and unpaid loss adjustment expenses ("LAE") for all lines of business.  These
reserves are intended to cover the probable ultimate cost of settling all
losses incurred and unpaid, including those incurred but not reported.  The
determination of reserves for losses and LAE for insurance companies such as
Navigators is dependent upon the receipt of information from the various pools
in which such companies participate.  Generally, there is a lag between the
time premiums are written and related losses and LAE are incurred, and the time
such events are reported to the pools and, subsequently, to Navigators.


                                       4




<PAGE>   6


     Navigators establishes reserves for reported claims when Navigators first
receives notice of the claim.  In the case of direct business and assumed
excess of loss reinsurance, reserves are established by Navigators on a
case-by-case basis by evaluating several factors, including the type of risk
involved, knowledge of the circumstances surrounding such claim, severity of
injury or damage, the potential for ultimate exposure, experience of Navigators
with the insured and the broker on the line of business, and the policy
provisions relating to the type of claim.  Navigators also establishes reserves
for proportional treaty claims based on reports received from ceding insurers
or pools in which they participate.  Reserves for incurred but not reported
losses for all of Navigators' business are determined, in part, on the basis of
statistical information and in part on industry experience.

     At any time, loss reserves are only estimates of what the insurer or
reinsurer expects to pay on claims, based on facts and circumstances then
known, and it is possible that the ultimate liability may exceed or be less
than such estimates.  Such estimates are based, among other things, on
predictions of future events and estimates of future trends in claim severity
and frequency.  During the loss settlement period, which, in some cases, may
last several years, additional facts regarding individual claims may become
known and, accordingly, it often becomes necessary to refine and adjust the
estimates of liability on a claim upward or downward.  Even then, the ultimate
liability may exceed or be less than the revised estimates.  The reserving
process is intended to provide implicit recognition of the impact of inflation
and other factors affecting loss payments by taking into account changes in
historical payment patterns and perceived probable trends.  There is generally
no precise method, however, for the subsequent evaluation of the adequacy of
the consideration given to inflation or to any other specific factor, because
the eventual deficiency or redundancy of reserves is affected by many factors,
some of which are interdependent.

     Navigators records only those premiums which are reported to it through
the end of each calendar year.  However, Navigators does estimate premiums
related to quarterly reports from the pool manager which have not been received
prior to preparation of the financial statements.  There are two types of
premium reporting lags to which Navigators may be subject.  First, there is an
inherent delay in the reporting of treaty reinsurance due to the fact that
there is a lag between the time that premium and loss activity is recorded on
the books of the reinsureds and the time the reinsured reports those activities
to the reinsurer.  Second, a substantial portion of the premiums Navigators
derives is from international business.  In this business, there is a
significant time lag from the time the policy is bound overseas to the receipt
of the policy by the pool manager, at which time the pool manager records the
premium in its records.  Considerable premium relating to a fiscal year is
reported in subsequent years at the pool level and, therefore, at Navigators as
well.  To the extent a lag exists in the reporting of, and Navigators'
accounting for, such premiums, a comparable lag occurs in this recording of
related incurred but not reported losses and LAE which properly matches
recorded revenue with related expenses.

     Navigators does not discount its reserves in an attempt to estimate the
present value of losses or LAE that may eventually be paid or for any other
reason.  The accompanying tables present an analysis of losses and LAE.

</TABLE>

     The table below presents the development of Navigators' GAAP balance sheet
reserves for 1986 through 1996.  The line "Net reserves for losses and LAE"
reflects the net reserves at the balance sheet date for each of the indicated
years and represents the estimated amount of losses and LAE arising in all
prior years that are unpaid at the balance sheet date.  The "Reserves
re-estimated" lines of the table reflect the re-estimated amount of the
previously recorded reserves 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.  The "Cumulative
redundancy (deficiency)" lines of the table reflect the cumulative amounts
developed as of successive years with respect to the aforementioned reserve
liability.  The cumulative redundancy or deficiency represents the aggregate
change in the estimates over all prior years.

     For each calendar year end, the net reserves for losses and LAE are not
adjusted in the table to reflect additional premiums reported to Navigators in
subsequent calendar years.  However, the remainder of the table allocates
losses and LAE reported and recorded in subsequent years to all prior years
starting with the year in which the loss was incurred.  For example, assume
that a loss occurred in 1994 and was not reported to Navigators until 1996, the
amount of such loss will appear as a deficiency in both 1994 and 1995, although
the premiums related to the policy may not be reported in income until 1995.
Conditions and trends that have affected development of the liability in the
past may not necessarily occur in the future.  Accordingly, it may not be
appropriate to extrapolate future redundancies or deficiencies based on these
tables.

     The net cumulative deficiencies for the years ended December 31, 1989
through 1992 resulted primarily from the allocation of losses to the
appropriate calendar years without regard to any additional premiums relating
to such calendar years which were reported to and recorded by Navigators in
subsequent periods.  These deficiencies are offset, in part, by additional net
earned premiums for such respective calendar years reported and recorded by
Navigators in subsequent years.  The net deficiency for 1994 resulted from
further development of losses from the Northridge, California earthquake
(discussed below).  The Company had net cumulative redundancies for the
remainder of the years shown in the table.

     The gross cumulative deficiencies for the years ended December 31, 1992
through the year 1995, resulted primarily from a settlement during 1996 of the
Exxon Valdez loss occurring in 1989, of approximately $11,300,000, development
during 1995 of approximately $26,000,000 for the 1994 Northridge Earthquake
loss and other losses that developed to a lesser extent during this period.  A
majority of the development of these losses was reinsured.

     Management believes that Navigators' reserves for losses and LAE are
adequate to cover the ultimate cost of losses and LAE on reported and
unreported claims.

ENVIRONMENTAL POLLUTION AND ASBESTOS RELATED CLAIMS

     In 1996 and 1995, Navigators paid a gross amount of $2,794,000 and
$2,251,000 and a net amount of $425,000 and $117,000, respectively, for
environmental pollution and asbestos related claims.  As of December 31, 1996
and 1995, Navigators carried a gross reserve of $5,421,000 and $4,783,000,
respectively, and net reserve of $1,042,000 and $876,000, respectively, for the
potential exposure of Navigators to such claims.  Management believes that its
reserves for such claims are adequate, because Navigators' participation in
such risks is generally in the higher excess layers and, based on a continuing
review of such claims, management believes that a majority of these claims will
be unlikely to penetrate such high excess layers of coverage.  For the year
ended December 31, 1996 and 1995, open claims with environmental pollution and
asbestos exposure amounted to 2,024 and 1,594, respectively.  Management will
continue to review its exposure to and reserves for such claims.  Management
believes that any potential exposure of Navigators to these claims exists
predominately in connection with the marine business.

INVESTMENT POLICY

     The investments of the Company's various subsidiaries must comply with the
insurance laws of New York State, the domiciliary state of Navigators Insurance
Company and NIC Insurance Company.  These laws prescribe the kind, quality and
concentration of investments which may be made by insurance companies.  In
general, these laws permit investments, within specified limits and subject to
certain qualifications, in federal, state and municipal obligations, corporate
bonds, preferred stocks and common stocks, real estate mortgages and real
estate.  Navigators has no investment in derivatives, and its investment
guidelines preclude the acquisition of derivatives.

     Navigators' investments are subject to the direction and control of its
Board of Directors and are reviewed on a quarterly basis.  The investments are
managed by various professional fixed income and equity portfolio managers.
Current investment objectives are to maximize annual after tax income in the
context of preserving and enhancing capital and statutory surplus.  Navigators
seeks to obtain these objectives by investing principally in municipal bonds
and, U.S. Government obligations, corporate bonds, and preferred and common
stock.  Due to the Company being in an alternative minimum tax ("AMT")
position, the Finance Committee of the Board of Directors is reviewing the
Company's concentration in municipal bonds and is likely to reduce the
municipal bond portfolio in 1997.  Navigators' investment guidelines require
that at least 90% of the fixed income portfolio be rated "A-" or better by a
nationally recognized rating organization.  Up to 25% 

                                       8




<PAGE>   10

of the total portfolio may be invested in equity securities including 
preferred stocks rated at BBB-/Baa-.

     In order to achieve the above-mentioned investment objectives, fixed
maturity securities are held for an indefinite period of time.  These
securities may be sold in response to changes in interest rates, prepayments,
regulatory requirements, or credit risk.

     The majority of the investment income of the Somerset Companies is derived
from fiduciary funds invested in accordance with the guidelines of various
state insurance departments.  These guidelines typically require investments in
short-term instruments.

     The following tables reflect the consolidated investments of the Company.
The table set forth below reflects investments and income earned thereon for
the Company on a consolidated basis, for Navigators Insurance Company and NIC
Insurance Company together as a group (including an incidental amount from the
parent company), and for the Somerset Companies together as a group, for the
three years ended December 31, 1996:

REGULATION

     The Company and its insurance subsidiaries are subject to regulation under
the insurance statutes, including holding company statutes, of various states.
These regulations vary from state to state but generally require insurance
holding companies, and insurers that are subsidiaries of holding companies, to
register and file reports concerning their capital structure, ownership,
financial condition and general business operations.  Such regulations also
generally require prior regulatory agency approval of changes in control of an
insurer and of transactions within the holding company structure.  The
regulatory agencies of each state have statutory authorization to enforce their
laws and regulations through various administrative orders and enforcement
proceedings.

     The Insurance Department of the State of New York (the "New York
Department") is the Company's principal regulatory agency.  In 1996, Navigators
Insurance Company was deemed to be "commercially domiciled" in California based
on past premium volume written in the state and, as a result, the Company was
subject to certain provisions of the California insurance holding company laws,
particularly those governing changes in control, the payment of stockholder
dividends and intercompany transactions.  An insurer's status as "commercially
domiciled" is determined annually under a statutory formula.  The statutory
formula was revised in California effective January 1, 1997, and as a result,
Navigators Insurance Company is no longer deemed to be "commercially domiciled"
in California as of such date.

     The New York Insurance Law provides that no corporation or other person
may acquire control of the Company, and thus indirect control of Navigators,
unless it has given notice to Navigators, and obtained prior written approval
of the Superintendent of Insurance of the State of New York for such
acquisition.  In New York, any purchaser of 10% or more of the outstanding
shares of the Company's common stock would be presumed to have acquired control
of the Company, unless such presumption is rebutted.

                                       10




<PAGE>   12


     Navigators Insurance Company and NIC Insurance Company may pay dividends
only out of their statutory earned surplus under New York law.  Generally, the
maximum amount of dividends Navigators Insurance Company and NIC Insurance
Company may pay without regulatory approval in any twelve-month period is the
lesser of adjusted net investment income or 10% of statutory surplus.

     Under insolvency or guaranty laws in most states in which Navigators
Insurance Company and NIC Insurance Company operate, insurers doing business in
those states can be assessed up to prescribed limits for policyholder losses of
insolvent insurance companies.

     Navigators Insurance Company is licensed to engage in the insurance and
reinsurance business in 47 states, the District of Columbia and Puerto Rico and
is an approved reinsurer in two of the remaining three states.  NIC Insurance
Company is licensed to engage in the insurance and reinsurance business in the
State of New York and is an approved surplus lines insurer in 29 other states
and the District of Columbia.

     As part of its general regulatory oversight process, the New York
Department conducts detailed examinations of the books, records and accounts of
New York insurance companies every three to five years.  Navigators Insurance
Company and NIC Insurance Company are currently being examined by the New York
Department for the years 1991 through 1995.

     The Insurance Regulatory Information System ("IRIS") was developed by the
National Association of Insurance Commissioners ("NAIC") and is intended
primarily to assist state insurance departments in executing their statutory
mandates to oversee the financial condition of insurance companies operating in
their respective states.  IRIS identifies eleven industry ratios and specifies
"usual values" for each ratio.  Departure from the usual values on four or more
of the ratios can lead to inquiries from individual state insurance
commissioners as to certain aspects of an insurer's business.  As of December
31, 1994 and 1995, due primarily to losses from the Northridge Earthquake
(discussed in item 7), the Company's results were outside of the usual value
for one ratio (the "Two-Year Overall Operating" ratio).  As of December 31,
1996, the Company's results were within the usual values for all IRIS ratios.

     From time to time various regulatory and legislative changes have been
proposed in the insurance and reinsurance industry, some of which could have an
effect on reinsurers.  Among the proposals that have in the past been or are at
present being considered are the possible introduction of federal regulation in
addition to, or in lieu of, the current system of state regulation of insurers
and proposals in various state legislatures (some of which proposals have been
enacted) to conform portions of their insurance laws and regulations to various
model acts adopted by the NAIC.  The Company is unable to predict whether any
of these laws and regulations will be adopted, the form in which any such laws
and regulations would be adopted, or the effect, if any, these developments
would have on the operations and financial condition of the Company.

     State insurance departments have adopted a methodology developed by the
NAIC for assessing the adequacy of statutory surplus of property and casualty
insurers which includes a risk-based capital formula that attempts to measure
statutory capital and surplus needs based on the risks in a company's mix of
products and investment portfolio.  The formula is designed to allow state
insurance regulators to identify potential weakly capitalized companies.  Under
the formula, a company determines its "risk-based capital" ("RBC") by taking
into account certain risks related to the insurer's assets (including risks
related to its investment portfolio and ceded reinsurance) and the insurer's
liabilities (including underwriting risks related to the nature and experience
of its insurance business).  The risk-based capital rules provide for different
levels of regulatory attention depending on the ratio of a company's total
adjusted capital to its "authorized control level" of RBC.  Based on
calculations made by the Company, the risk-based capital level for the
Company's insurance subsidiaries exceeds a level that would trigger regulatory
attention.  In their respective 1996 statutory financial statements, the
Company's insurance subsidiaries have complied with the NAIC's risk-based
capital reporting requirements.

                                       11

     In addition to regulations applicable to insurance agents generally, the
Somerset Companies are subject to Managing General Agents Acts in their
domicile jurisdictions and in certain jurisdictions where they do business.

COMPETITION

     The property and casualty insurance industry is highly competitive.  The
demand for low-cost, high quality service has created difficult conditions in
the domestic property and casualty market, including a leveling or reduction in
premium rates in certain lines of business in which the Company competes, which
the Company believes will not improve dramatically in the foreseeable future.

     Navigators faces competition from both domestic and foreign marine,
aviation and non-marine insurers, some of whom have longer operating histories
and greater financial, marketing and management resources.  Competition in the
types of insurance in which Navigators is engaged is based on many factors,
including the perceived overall financial strength of Navigators, pricing and
other terms and conditions of products and services offered, business
experience, marketing and distribution arrangements, agency and broker
relationships, levels of customer service (including speed of claims payments),
product differentiation and quality, operating efficiencies and underwriting.
Furthermore, insureds tend to favor large, financially strong insurers, and
Navigators faces the risk that it will lose market share to more highly rated
insurers.

     No single insured or reinsured accounted for 10% or more of the Company's
gross written premium in 1996.

EMPLOYEES

     As of December 31, 1996, the Company employed 119 people.

ITEM 2. PROPERTIES

     The Company's administrative offices are occupied pursuant to a lease
which expires May 14, 2000, from an unaffiliated company, in a building located
at 123 William Street, New York, New York.  Each of the Somerset Companies has
various noncancellable operating leases for its office facilities.  The Company
does not own any real estate.

ITEM 3. LEGAL PROCEEDINGS

     Neither the Company nor any of its subsidiaries is a party to or the
subject of, any material pending legal proceedings which depart from the
ordinary routine litigation incident to the kinds of business conducted by the
Company and its subsidiaries.

     In November 1988, the voters of the State of California approved
Proposition 103, which required most property and casualty insurance companies,
among other things, to reduce rates charged to California insureds to a level
20% below November 8, 1987 levels.  On March 19, 1996, the Company agreed with
the California Insurance Department to settle its rollback liability under
Proposition 103.  The settlement cost the Company approximately $2.0 million
net of recoveries from reinsurers of which $1.0 million was recorded in each of
1995 and 1996.

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

GENERAL

     The Company is a holding company with twelve active wholly-owned
subsidiaries.  See "BUSINESS-General" included herein for a description of the
Company.

     The Company's revenue is primarily comprised of premiums, commissions and
investment income.  Navigators derives substantially all of its business from
direct participation in, or by reinsuring certain members of, insurance pools
managed by the Somerset Companies.  The insurance business and operations of
Navigators are managed by NMC, one of the Somerset Companies.

     The Somerset Companies specialize principally in the following lines of
business:  marine, aviation and property (primarily inland marine) insurance
and certain lines of specialty reinsurance and non-marine insurance.  In 1996,
Navigators began to underwrite onshore energy business primarily covering
property damage and machinery breakdown.  In 1996, the Somerset Companies
underwrote the marine business through a syndicate of insurance companies,
Navigators having the largest participation in the syndicate.  The Somerset
Companies derive their revenue from commissions, investment income, service
fees and cost reimbursement arrangements from Navigators and other insurers.
Commissions are earned both on a fixed percentage of premiums and on
underwriting profits on business placed with the participating insurance
companies within the syndicate.  Property and casualty insurance premiums are
cyclical in nature and, accordingly, during a "hard market" demand for property
and casualty insurance exceeds supply, or capacity, and as a result, premiums
and commissions may increase.  On the downturn of the property and casualty
cycle, supply exceeds demand, and as a result, premiums and commissions may
decrease.

     Navigators and the Somerset Companies earn investment income on cash
balances and invested assets.  The Somerset Companies also earn investment
income on fiduciary funds.  Such fiduciary funds are invested, subject to
applicable insurance regulations, primarily in short-term instruments.

RESULTS OF OPERATIONS

     General  The 1994 results of operations of the Company were dominated by
the Northridge, California earthquake, which occurred on January 17, 1994 (the
"Northridge Earthquake").  The Company's pre-tax loss (including direct
property losses of $35,388,000, reinsurance reinstatement premiums of
$1,925,000 and reinsurance assumed losses of $1,952,000, but net of
reinsurance) in 1994 from the Northridge Earthquake totalled $39,265,000.  As a
result of this loss, management restructured the Company by withdrawing from
the large commercial and industrial property business which produced most of
the earthquake loss, emphasizing its core ocean marine and aviation business,
and developing its inland marine business as well as a new non-marine program
book of business.

     The results of 1996 and 1995 reflect this restructuring in that written
premiums have been reduced while the continuing book of business has produced
profits. However, the 1995 results also reflect the further development of
losses from the Northridge Earthquake.  During 1995 the total reported gross
losses on direct property claims arising from the Northridge Earthquake
increased approximately $18,340,000 from $125,361,000 to $143,701,000.  The
Company also added gross bulk reserves of $11,000,000 at September 30, 1995,
which are expected to cover any further deterioration of losses from the
Northridge Earthquake.  On a net basis, the incurred losses relating to the
Northridge Earthquake represented pre-tax charges of approximately $10,721,000
in 1995.  There was no further development of the losses from the Northridge


                                       15

Earthquake in 1996, however, there can be no assurance given that additional
losses will not be reported or adjustments made to existing reserves.

     Revenues  Gross written premium decreased from $189.6 million in 1994 to
$148.9 million in 1995 to $142.5 million in 1996.  The following table sets
forth the Company's gross written premium by line of business and net written
premium in the aggregate for the periods indicated:

</TABLE>

     Marine Premiums.  Navigators' gross marine premium decreased 5% from 1994
to 1995 and 16% from 1995 to 1996.  The 1995 decrease was due to Navigators'
reduced participation in the marine pool along with premium rate decreases.
The 1996 decrease was due primarily to decreases in premium rates.  The
competition causing premium rates to decrease affects the gross written premium
in that less premium is received for the policies written or the Company may
decide to not write the policy.  Management believes pricing in marine premium
is subject to increased competition.

     Aviation Premiums.  Navigators' aviation gross written premium increased
6% from 1994 to 1995 reflecting the increase in Navigators' participation in
the aviation pool from approximately 56% for the first nine months of 1995 to
100% beginning October 1, 1995.  The 20% reduction in Navigators' aviation
gross written premium from 1995 to 1996 was due to Navigators withdrawing from
the general aviation business in order to concentrate on the major airlines and
manufacturers, to price competition and to a general decrease in the amount of
exposure per risk.

     Property and Inland Marine Premium.  Navigators' gross property and inland
marine premium decreased 75% from 1994 to 1995.  In 1994, this business
consisted primarily of large commercial and industrial property risks, which
was essentially a property catastrophe book of business, with a relatively
small amount of inland marine risks.  In late 1994, Navigators decided to cease
writing large commercial and industrial property risks and to concentrate on
inland marine risks and, therefore, 1995 gross written premium is primarily
inland marine.  The 25% increase in this line of business from 1995 to 1996
reflects the emphasis placed on inland marine in 1996.  However, due to heavy
price competition and possible adverse selection in competing with the major
carriers, less emphasis will be placed on inland marine going forward.


                                       16


<PAGE>   18

     Onshore Energy.  In 1996, Navigators began to underwrite onshore energy
business which principally focuses on the oil and gas, chemical and
petrochemical, and power generation industries with coverages primarily for
property damage and machinery breakdown.

     Specialty Reinsurance and Non-Marine Insurance Premium.  During the early
part of 1996, Navigators' management decided to discontinue writing assumed
reinsurance, with the exception of a few specialty contracts.  The reduction in
reinsurance premium was partially offset in 1996 by an expansion of the
specialty program business.

     Net Written Premium.  Navigators net written premium decreased 11% from
1994 to 1995 primarily due to the decrease in the property premium.  The 4%
increase in net written premium from 1995 to 1996 was primarily due to
Navigators increasing its participation in the aviation pool to 100% at October
1, 1995 and to less premium being ceded.  The decreases in the ceded premium
are reflective of decreases in the gross written premium but are also due to
price competition in the reinsurance business.

     Net Earned Premium.  The 3% decrease in net earned premium from 1994 to
1995 was due to the decrease in the net written premium partially offset by the
run-off of the property business cancelled in 1994 and 1995.  The 10% decrease
in net earned premium from 1995 to 1996 was primarily due to the decrease in
the 1995 net written premium and the effect that the property business run-off
had on the 1995 net earned premium.

     Commission Income.  Commission income decreased 17% to $8.8 million in
1996 from $10.7 million in 1995 primarily due to Navigators increasing its
participation to 100% at October 1, 1995 in the aviation business managed by
the Somerset Companies, which eliminated commission income paid by the former
participants in the aviation insurance pool.  The 1996 commission income
includes $826,000 of profit commissions earned under the Company's management
agreement with Riverside.  Commission income decreased 2% to $10.7 million in
1995 from $10.9 million in 1994 reflecting the withdrawal from the property
catastrophe business.  The commission income is also affected by profit
commissions from the marine pool.

     Net Investment Income.  Net investment income decreased 4% to $13.6
million in 1996 from $14.1 million in 1995 due to decreased fiduciary funds
held by the Somerset Companies, the effect on invested assets from payments of
earthquake losses and generally lower yields.  Net investment income increased
9% to $14.1 million in 1995 from $13.0 million in 1994 due primarily to an
increased amount of invested assets.

     Reinsurance Ceded.  In the ordinary course of business, Navigators
reinsures certain insurance risks with unaffiliated insurance companies for the
purpose of limiting its maximum loss exposure, protecting against catastrophic
losses, and maintaining desired ratios of net premiums written to statutory
surplus.  Ceded written premium decreased from $98.0 million in 1994 to $67.6
million in 1995 to $58.4 million in 1996 reflecting decreases in gross written
premium and lower prices in the reinsurance market.

     Expenses.  The ratio of loss and loss adjustment expenses incurred to net
earned premium  was 62.2%, 69.5% and 108.6% in 1996, 1995 and 1994,
respectively.  The 1994 loss ratio was adversely impacted by the Northridge
Earthquake.  The loss ratio improved in 1995 compared to 1994, even though 1995
included significant adverse development from the Northridge Earthquake losses.
This was due primarily to a return to more normal experience in comparison to
the 1994 losses from the Northridge Earthquake, various airline losses and
reinsurance costs in 1994.  The Northridge Earthquake increased the loss ratio
by 12.2% and 43.4% in 1995 and 1994, respectively.  The improved loss ratio in
1996 compared to 1995 was due primarily to a return to more normal experience.
The lower rates in the marine business was partially offset by lower costs for
reinsurance.

     Commission expense as a percentage of net earned premium was 15.5%, 13.9%
and 19.0% for 1996, 1995 and 1994, respectively.  The decrease in 1995 compared
to 1994 was due primarily to a reduction in the amount of Northridge Earthquake
reinstatement premiums incurred during the year.  The reinstatement premiums in
1994 caused earned premiums to decline but did not result in corresponding
ceding commissions.  The increase in the 1996 commission expense ratio compared
to 1995 was primarily due to the reversal of approximately $519,000 of
contingent commissions receivable recorded in 1995 on certain ceded contracts
which had loss development during 1996.

     Other operating expenses as a percentage of net earned premium were 24.5%,
25.6% and 24.0% for 1996, 1995 and 1994, respectively.  Severance charges as a
result of a reduction in staff accounted for approximately $968,000 of the
operating expenses in 1995 partially offset by a commensurate decrease in salary
expense.  The decrease from 1995 to 1996 reflected the staff cuts in 1995
partially offset by the opening of the new offices in London and Australia in
late 1996.

     Interest expense is due primarily to funds borrowed in 1994 to replace
capital as a result of losses from the Northridge Earthquake.  The decrease in
the interest expanse from 1995 to 1996 is due primarily to paying down part of
the loan balance and lower interest rates.  The 1996 and 1995 interest expense
includes $368,000 and $380,000 of interest expense on the Company's rollback
liability under California Proposition 103.

     Income Taxes.  The income tax expense was $4.7 million for 1996 and $3.0
million for 1995.  There was an income tax benefit of $11.0 million for 1994
primarily attributable to the losses from the Northridge Earthquake.  The
effective tax rates for 1996, 1995 and 1994 were 20%, 19% and (35%),
respectively.  The Company had net operating loss carryforwards of $4.9 million
at December 31, 1994 and $3.0 million at December 31, 1995 which was fully
utilized in 1996.  The Company had alternative minimum tax ("AMT")
carryforwards of $5.8 million, $3.1 million and $0.8 million at December 31,
1996, 1995 and 1994, respectively.  The AMT carryforwards were primarily
attributable to the tax benefits from the municipal bond interest.  The Company
is reviewing its investment philosophy and will most likely reduce its
municipal bond portfolio.

     As of December 31, 1996 the net deferred Federal tax asset was $9.5
million as compared to $8.9 million at December 31, 1995.  At December 31, 1995
the Company had a $775,000 valuation allowance against its deferred Federal tax
asset.  Management believes that it is more likely than not that the net
deferred Federal tax asset recorded at December 31, 1996 is realizable and
therefore, has not provided for any valuation allowance at December 31, 1996.
This belief stems from a long history of taxable income prior to the Northridge
Earthquake in 1994, the immediate actions management took to prevent another
loss of such magnitude, and the inclusion of taxable income generated by the
Somerset Companies in the Federal income tax return beginning July 1, 1994.

     Equity Income in Affiliated Company.  The Company holds an equity interest
in Riverside, which through its wholly-owned subsidiary, Riverside Corporate
Underwriters Limited, is admitted to underwrite at Lloyd's of London as a
corporate name with limited liability.  The Company records its share of
Riverside's underwriting results when sufficient information becomes available
to provide reasonable estimates of earned premiums and losses.  During 1996,
primarily in the third quarter, the Company recorded its share of the 1994 and
1995 underwriting earnings amounting to $1,387,942 after tax.

     Net Income.  The Company's net income improved in 1995 to income of $12.6
million from a loss of $20.5 million in 1994.  The 1994 loss was primarily
attributable to the Northridge Earthquake which also adversely impacted 1995
earnings as previously discussed. The 1996 net 



                                       18

income of $16.8 million reflects
more normal experience even with the rate decreases in the marine business.

     In November 1988, the voters of the State of California approved
Proposition 103, which required most property and casualty insurance companies,
among other things, to reduce rates charged to California insureds to a level
20% below November 8, 1987 levels.  On March 19, 1996, the Company agreed with
the Commissioner to settle its rollback liability under Proposition 103.  The
settlement cost the Company approximately $2.0 million net of recoveries from
reinsurers of which approximately $1.0 million was recorded in each of 1995 and
1996.

LIQUIDITY AND CAPITAL RESOURCES

     Cash flow from operations was $7.3 million, $26.6 million and $5.3 million
for 1996, 1995 and 1994, respectively.  Operating cash flow has been used
primarily to acquire additional investment assets with net purchases during
1996, 1995 and 1994 of $11.5 million, $12.8 million and $11.2 million,
respectively.

     At December 31, 1996, there were no material commitments for capital
expenditures, although the Company has committed approximately $1.0 million to
enhance its hardware and software computer systems in 1997.

     Invested assets and cash (excluding fiduciary funds held by the Somerset
Companies) have grown from $203.1 million at December 31, 1994 to $235.5
million at December 31, 1995 to $240.7 million at December 31, 1996.
Investment income during this period was $13.0 million in 1994, $14.1 million
in 1995 and $13.6 million in 1996.  The average yield of the portfolio,
excluding net realized capital gains, was 5.7% in 1994 and 1995 and decreased
to 5.4% in 1996, reflecting the prevailing interest rates during those years.
As of December 31, 1996, all debt and equity securities held by the Company
were classified as available-for-sale securities.

     The majority of the invested assets are in municipal bonds rated "A" or
better by Standard & Poor's or Moody's, or are in U.S. Treasury Bonds.
Navigators has avoided investing in high yield bonds.  Therefore, the Company
has no significant exposure to credit risk since the Company's fixed maturity
investment portfolio does not contain any non-investment grade bonds.  The
portfolio has an average maturity of less than seven years.  Management
continually monitors the composition and cash flow of the investment portfolio
in order to maintain the appropriate levels of liquidity.  This ensures the
Company's ability to satisfy claims or expenses as they become due.

     The Company's credit agreement, which was amended on November 19, 1996
(the "Amended Credit Agreement"), provides for a $20 million revolving credit
loan facility of which $17 million was being utilized at December 31, 1996 and
a $30 million letter of credit facility of which $27.1 million (In Pounds
Sterling 15.8 million)
was being utilized at December 31, 1996.  The letters of credit consist of
In Pounds Sterling 2,585,000 for the Company's portion of the business
conducted by Riverside and In Pounds Sterling 7,000,000 and In Pounds Sterling
6,250,000 for 1997 capacity being provided for two separate Lloyd's of London
marine syndicates.  The Amended Credit Agreement is collateralized by shares of
common stock of the active subsidiaries of the Company other than NIC Insurance
Company and Somerset Asia Pacific Pty Limited. The Amended Credit Agreement
contains covenants common to agreements of this type. The aggregate amounts
available under the revolving credit loan facility decrease in quarterly
increments in the amount of $500,000 commencing with the quarter beginning
January 1, 1997 through the quarter ended September 30, 1999, and in varying
increments thereafter through December 31, 2002.  See Note 4 to the Company's
Consolidated Financial Statements.

     Total stockholders' equity was $115.5 million at December 31, 1996, a
16.6% increase for the year primarily as the result of the Company's earnings
in 1996.

     As of December 31, 1996, the Company has paid approximately $128.4 million
of claims related to the Northridge Earthquake, of which approximately $94.8
million is subject to indemnification by reinsurers.  To date the Company has
experienced no significant difficulties collecting reinsured losses.

     The Company was not in compliance with the NAIC's IRIS "Two-Year Overall
Operating" ratio in 1995.  The exceptional value derived from this ratio was
primarily due to the underwriting losses resulting from the Northridge
Earthquake.  If the Two-Year Overall Operating ratio is 100% or more, the NAIC
deems such results to be exceptional.  During 1995, the Company's Two-Year
Overall Operating ratio was 115%.  The Company was within the usual values for
all IRIS ratios as of December 31, 1996.

     The Company's reinsurance has been placed with various U.S. companies
rated "A" or better by A.M. Best Company, Inc., as well as with foreign
insurance companies and with selected syndicates of Lloyd's of London
("Lloyd's").  Certain syndicates at Lloyd's ("Loss Syndicates") and the Lloyd's
market as a whole have reported significant losses in recent years.  The
Company has not placed any material amounts of reinsurance with these Loss
Syndicates.  Pursuant to the implementation of Lloyd's Plan of Reconstruction
and Renewal, a significant portion of the Company's recoverables from the Loss
Syndicates are now reinsured by Equitas (a separate U.K. Department of Trade
authorized reinsurance company established to reinsure outstanding liabilities
of all Lloyd's members for all risks written in the 1992 or prior years of
account).

     The Company believes that the cash flow generated by the operating
activities of the Company's subsidiaries, including the Somerset Companies,
will provide sufficient funds for the Company to meet its liquidity needs over
the next twelve months.  Beyond the next twelve months, cash flow available to
the Company may be influenced by a variety of factors, including general
economic conditions and conditions in the insurance and reinsurance markets, as
well as fluctuations from year to year in claims experience.

ECONOMIC CONDITIONS

     The Company is a specialty insurance company and periods of moderate
economic recession or inflation tend not to have a significant direct effect on
the Company's underwriting operations.  They do, however, impact the Company's
investment portfolio.  In 1996, the Company's yield on its invested assets
declined and the Company's investment income was negatively impacted by lower
yields.

     Management considers the potential impact of these economic trends in
estimating Navigators' loss reserves.  Management believes that the
underwriting controls it maintains, plus the fact that the majority of
Navigators' business is in lines of insurance which have relatively short loss
payout patterns, both assist in estimating more accurately ultimate claim costs
and lessen the potential adverse impact of the economy on Navigators.

                          INDEPENDENT AUDITORS' REPORT

The Board of Directors and Stockholders
The Navigators Group, Inc.

     We have audited the consolidated financial statements of The Navigators
Group, Inc. and subsidiaries as listed in the accompanying index.  In
connection with our audits of the consolidated financial statements, we also
have audited the consolidated financial statement schedules as listed in the
accompanying index.  These consolidated financial statements and financial
statement schedules are the responsibility of the Company's management.  Our
responsibility is to express an opinion on these consolidated financial
statements and financial statement schedules 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 financial position of The
Navigators Group, Inc. and subsidiaries as of December 31, 1996 and 1995, and
the results of their operations and their cash flows for each of the years in
the three-year period ended December 31, 1996, in conformity with generally
accepted accounting principles.  Also in our opinion, the related financial
statement schedules, when considered in relation to the basic consolidated
financial statements taken as a whole, present fairly, in all material
respects, the information set forth therein.

     As discussed in Note 1 to the consolidated financial statements, The
Navigators Group, Inc. and subsidiaries changed their method of accounting for
certain investments in debt and equity securities in 1994.

                   NOTES TO CONSOLIDATED FINANCIAL STATEMENTS


NOTE 1. --ORGANIZATION AND SUMMARY OF SIGNIFICANT ACCOUNTING POLICIES

     The accompanying consolidated financial statements, which include the
accounts of The Navigators Group, Inc. (the "Group" or the "Company") and its
subsidiaries, are prepared on the basis of generally accepted accounting
principles.  All significant intercompany transactions and balances are
eliminated.

     On June 30, 1994, the stockholders of the Group approved eight
substantially identical agreements of merger providing for the acquisition by
the Group of eight affiliated underwriting agencies, Somerset Marine, Inc.,
Somerset of Georgia, Inc., Somerset Insurance Services of Texas, Inc., Somerset
Insurance Services of California, Inc., Somerset Insurance Services of
Washington, Inc., Somerset Property, Inc., Somerset Re Management, Inc. and
Navigators Management Corporation (collectively known as the "Acquired Somerset
Companies").

     The Group issued 2,875,000 shares of its common stock for all the
outstanding common stock of the Acquired Somerset Companies.  The mergers were
accounted for under a method of accounting similar to "pooling of interests."
Prior to the mergers, the consolidated financial statements of the Group and
subsidiaries included the accounts of Navigators Insurance Company and NIC
Insurance Company (collectively known as the "Insurance Companies").  As of the
date of the mergers and for all prior periods presented, the consolidated
financial statements of the Group and subsidiaries include the accounts of the
Insurance Companies and the Acquired Somerset Companies.

     The Company is a holding company which owns the Insurance Companies, the
Acquired Somerset Companies and five other subsidiaries:  Somerset Asia Pacific
Pty Limited ("Somerset Asia"), an agency office located in Sydney, Australia;
Somerset Marine (UK) Limited ("Somerset  (UK)"), agency office located in
London, England; Navigators Corporate Underwriters Limited, a corporate member
admitted to underwrite at Lloyd's of London with limited liability; and
Somerset Casualty Agency, Inc. and Somerset Aviation Property Managers, Inc.,
which are inactive.  The Acquired Somerset Companies (other than Somerset
Property, Inc. which is inactive), Somerset Asia  and Somerset (UK) are
hereinafter referred to collectively as the "Somerset Companies".  The Somerset
Companies specialize in underwriting marine, aviation and property (primarily
inland marine) insurance and certain lines of specialty reinsurance and
non-marine insurance.  The Insurance Companies derive substantially all of
their business from the Somerset Companies through either business written
specifically for the Insurance Companies or direct participation in, or by
reinsuring certain members of, insurance pools managed by the Somerset
Companies.  In addition to the Insurance Companies' participation in the
insurance pools, ten other non-affiliated insurance companies participate, for
which commission income is earned as reflected in the consolidated income
statement.  Commission expense as reflected in the consolidated income
statements represents the Insurance Companies' portion of acquisition costs
incurred by the Somerset Companies from non-affiliated brokers and agents.

INVESTMENTS

     Effective January 1, 1994, the Company adopted the Financial Accounting
Statements Board's ("FASB") Statement of Financial Accounting Standard ("SFAS")
115 "Accounting for Certain Investments in Debt and Equity Securities." pSFAS
115 addresses the accounting and reporting for investments in equity securities
that have readily determinable fair values and all investments in debt
securities.  Under SFAS 115, investments are classified into three categories.
Held-to-maturity securities are debt securities that the Company has the
positive intent and ability to hold to maturity and are reported at amortized
cost.  Trading securities are debt and equity securities that are bought and
held principally for the purpose of selling them in the near term and are
reported at fair value, with unrealized gains and losses included in earnings.
Available-for-sale securities are debt and equity securities not classified as
either held-to-maturity securities or trading securities and are reported at
fair value, with unrealized gains and losses excluded from earnings and
reported as a separate component of stockholders' equity.  As of December 31,
1996 and 1995, all debt and equity securities held by the Company were
classified as available-for-sale securities.

THE NAVIGATORS GROUP, INC. AND SUBSIDIARIES
NOTES TO CONSOLIDATED FINANCIAL STATEMENTS (CONTINUED)



     Short-term investments are carried at cost, which approximates fair value.
Short-term investments mature within one year from the purchase date.

     Realized gains and losses on sales of investments are determined on the
basis of the specific identification method.  When a decline in fair value of
investments is considered to be "other than temporary," the investments are
written down to net realizable value.  The write down is considered a realized
loss in the consolidated statement of income.

PREMIUM REVENUES

     Insurance and reinsurance premiums are recognized as income by the
Insurance Companies during the terms of the related policies based on reports
received from the Somerset Companies and ceding reinsurers.  Unearned premium
reserves are established to cover the unexpired portion of premiums written.

COMMISSION INCOME

     Commission income, based on estimated gross premiums earned from
non-affiliated insurers, is recognized over the terms of the related policies.
Contingent commission income, based on estimated net underwriting results from
non-affiliated insurers, is recognized when ascertained and is included within
commission income in the accompanying consolidated financial statements.
Changes in prior estimates of commission income and contingent commission
income are recorded when such changes become known.

DEFERRED POLICY ACQUISITION COSTS

     Costs of acquiring business which vary with and are directly related to
the production of business are deferred and amortized ratably over the period
that the related premiums are recognized as earned.  Such costs primarily
include commission expense, certain management fees and premium taxes.  The
method of computing deferred policy acquisition costs limits the deferral to
their estimated net realizable value based on the related unearned premiums and
takes into account anticipated losses and loss adjustment expenses based on
historical and current experience and anticipated investment income.

RESERVE FOR LOSSES AND LOSS ADJUSTMENT EXPENSES

     Unpaid losses and loss adjustment expenses are determined on an individual
basis for reported claims from insureds, from reports received from ceding
insurers for insurance assumed from such insurers and on estimates based on
Company and industry experience for incurred but not reported claims and loss
adjustment expenses.  The provision for unpaid losses and loss adjustment
expenses has been established to cover the estimated unpaid cost of claims
incurred.  Management believes that the unpaid losses and loss adjustment
expenses are adequate to cover the ultimate unpaid claims incurred; however,
such provisions are necessarily based on estimates and, accordingly, no
representation is made that the ultimate liability will not exceed such
amounts.

NET INCOME PER SHARE

     Net income per share is based on the weighted average number of shares of
common stock outstanding, and, if dilutive, shares issuable under stock option
plans.

REINSURANCE CEDED

     With respect to reinsurance ceded which transfers risk, premiums,
commissions and recoveries on losses incurred are reflected as reductions of
the respective income and expense accounts.  Unearned premiums ceded and
estimates of amounts recoverable from reinsurers on paid and unpaid losses are
reflected as assets.

NOTES TO CONSOLIDATED FINANCIAL STATEMENTS (CONTINUED)

FEDERAL INCOME TAXES

     The Company files a consolidated Federal tax return, which includes the
taxable income of its subsidiaries.  For 1994, taxable income excluded the
Acquired Somerset Companies taxable income from the beginning of the period,
January 1, 1994, to the date of the consummation of the mergers, June 30, 1994
(see Note 7).  The Company applies the asset and liability method of accounting
for income taxes.  Under the asset and liability method, deferred tax assets
and liabilities are recognized for the future tax consequences attributable to
differences between the financial statement carrying amounts of existing assets
and liabilities and their respective tax bases.  Deferred tax assets and
liabilities are measured using enacted tax rates expected to apply to taxable
income in the years in which those temporary differences are expected to be
recovered or settled.  The effect on deferred tax assets and liabilities of a
change in tax rates is recognized in income in the period that includes the
enactment date.

FAIR VALUES OF FINANCIAL INSTRUMENTS

     Fair values for fixed maturity securities are based on independent pricing
services.  The fair values for equity securities are based on quoted market
prices.  Fair values of short-term investments are carried at cost, which
approximates fair value.  The fair value of the loans payable to banks
approximates carrying value since the interest rate charged is computed using
market rates.

USE OF ESTIMATES

     The preparation of financial statements in conformity with generally
accepted accounting principles requires management to make estimates and
assumptions that affect the reported amounts of assets and liabilities and
disclosure of contingent assets and liabilities at the date of the financial
statements and the reported amounts of revenues and expenses during the
reporting period.  Actual results could differ from these estimates.

</TABLE>

     During 1994 realized losses of $926,000 were recognized on securities in
which the decline in fair value was other than temporary.  There were no such
declines in 1996 or 1995.

     At December 31, 1996 and 1995, fixed maturities with a face value of
$6,480,000 and $5,230,000 were on deposit with the various State Insurance
Departments.

     Also, at December 31, 1996 and 1995, fixed maturities with a face value of
approximately $841,000 were pledged as security under a reinsurance treaty.

     At December 31, 1996, the Company did not have a material concentration of
financial instruments in a single investee.

NOTE 3.--NORTHRIDGE EARTHQUAKE

     On January 17, 1994, an earthquake (the "Northridge Earthquake") occurred
in the vicinity of the Northridge area of Los Angeles, California.  The
Company's pre-tax loss (including direct property losses of $35,388,000,
reinsurance reinstatement premiums of $1,925,000 and reinsurance assumed losses
of $1,952,000, but net of reinsurance) in 1994 from the Northridge Earthquake
totalled $39,265,000.  During 1995, the Company incurred an additional
$10,721,000 pre-tax charge including a $4,500,000 net general reserve
established at the end of the third quarter of 1995.  The estimated total gross
reported loss on direct property claims is $143,701,000 at December 31, 1995
and $149,681,000 at December 31, 1996.  There can be no assurance given that
additional losses will not be reported or adjustments made to existing
reserves.

NOTE 4.--NOTES PAYABLE AND LOANS

     In conjunction with the mergers, the Acquired Somerset Companies
distributed $5,280,263 in the form of notes payable to the then existing
shareholders of the Acquired Somerset Companies.  These notes represent certain
pre-merger income to such shareholders and were interest free through December
31, 1994.  The remainder, $942,034 is due to the holder on demand.

     On August 5, 1994, the Company entered into a Credit Agreement (the
"Credit Agreement") with three banks.  The Credit Agreement provided for (i)
revolving credit loans up to $5,000,000 through August 5, 1997 (the "Revolving
Credit Loans"), (ii) a term loan of $25,000,000, the principal of which was
payable in quarterly installments due on June 30, 1997 (the "Term Loan"), and
(iii) and irrevocable stand-by letter of credit issued by one of the banks for
the benefit of Society of Lloyd's in the amount of L.2,585,0000 for the account
of the Company.  The Term Loan's principal was $17,500,000 and Revolving Credit
Loans were $2,000,000 at December 31, 1995.

THE NAVIGATORS GROUP, INC. AND SUBSIDIARIES
NOTES TO CONSOLIDATED FINANCIAL STATEMENTS (CONTINUED)

     On November 19, 1996, the Company amended and restated the Credit
Agreement (as amended and restated, the "Amended Credit Agreement").  The
Amended Credit Agreement provides for (i) a $20 million revolving credit loan
facility, under which the aggregate amount available will be reduced by
$500,000 for the first eleven quarters, and by varying amounts for the last
eight quarters, with the facility terminating on December 31, 2002 (the
"Revolving Credit Facility"), and (ii) a $30 million letter of credit facility
(the "Letter of Credit Facility").  The Revolving Credit Facility bears
interest, at the election of the Company, at either the base commercial lending
rate of one of the banks or at LIBOR plus 1%.  Any amounts drawn under the
Letter of Credit Facility and not repaid bear interest at the base commercial
lending rate of one of the banks.  At December 31, 1996, $17 million in loans
were outstanding under the Revolving Credit Facility (at an interest rate of
6.5%) and letters of credit with an aggregate face amount of L.15,835,000
(approximately U.S. $27,100,000 at the exchange rate as of December 31, 1996)
were issued under the Letter of Credit Facility.  No amounts were drawn under
the Letter of Credit Facility during the year.

     The Revolving Credit Facility and the Letter of Credit Facility are
collateralized by shares of common stock of the active subsidiaries of the
Company other than NIC Insurance Company and Somerset Asia Pacific Pty Limited.
The Amended Credit Agreement contains covenants common to transactions of this
type, including restrictions on indebtedness and liens, limitations on mergers
and the sale of assets, maintenance of consolidated total stockholders' equity,
statutory surplus, minimum liquidity, loss reserves and other financial ratios.

NOTE 5.--INVESTMENT IN AFFILIATE

     The investment in affiliate represents the Group's ownership interest in
Riverside Underwriters plc (formerly known as Navigators Underwriters plc)
("Riverside").  The Group's original ownership interest was 21% at December 31,
1995 which increased to 27% as of January 1, 1996 and decreased to
approximately 8% at December 31, 1996.  Riverside, a U.K. corporation, owned
100% of Riverside Corporate Underwriters Limited, a U.K. corporation, which has
been admitted to underwrite at Lloyd's of London as a corporate name with
limited liability.  The transaction to reduce the Company's ownership in
Riverside did not produce a material capital gain or loss.  The Company will,
however, remain entitled to receive from Riverside an amount equal to the
aggregate dividends that it would have received if it had continued to hold its
original investment to the extent such dividends are attributable to writings
at Lloyd's by Riverside Corporate Underwriters Limited during the 1994, 1995
and 1996 years of account.  In connection with the reduction of the Company's
investment, Navigators Management Corporation ("NMC") has agreed to cease being
manager of Riverside and Riverside Corporate Underwriters Limited, although NMC
will remain entitled to profit commissions with respect to the 1994, 1995 and
1996 underwriting years.  Prior to December 31, 1996, the investment was
carried under the equity method of accounting.  At December 31, 1996, the
investment is recorded at cost due to the reduction in ownership interest.  In
addition, the Company's Letter of Credit Facility (see Note 4) includes
L.2,585,000 (approximately U.S. $4,427,000 at the exchange rate as of December
31, 1996) to collateralize the investment in accordance with Lloyd's of London
requirements.

     Included in 1996 income is $1,387,942 of equity income, net of tax.  The
Company records its share of Riverside's earnings from underwriting when
sufficient information becomes available to provide reasonable estimates of
earned premiums and losses.  During 1996, information about Riverside's profits
for two years, 1994 and 1995, became available enabling the Company to record
the above income.

NOTE 6.--FIDUCIARY FUNDS

     The Somerset Companies maintain separate fiduciary accounts which record
all the underlying insurance transactions of the insurance pools which they
manage.  These transactions primarily include collecting premiums from the
insured, collecting paid recoverables from reinsurers, paying claims as losses
become payable, paying reinsurance premiums to reinsurers and remitting net
account balances to member insurance companies.  Unremitted amounts to members
of the insurance pools are held in a fiduciary capacity and interest income
earned on such funds inure to the benefit of the Somerset Companies.

NOTES TO CONSOLIDATED FINANCIAL STATEMENTS (CONTINUED)

     The mergers between the Group and the Somerset Companies were consummated
on June 30, 1994.  A business combination between an S Corporation and a
tax-paying corporation automatically terminates the S Corporation election.
The Somerset Companies prior to the mergers were S Corporations and as a result
of the mergers their tax status changed to C Corporations.  Accordingly, a
charge to earnings of $1,279,445 was recorded at June 30, 1994 to reflect taxes
on income previously earned but not yet taxed.  Therefore, as of July 1, 1994
and thereafter, taxable income of the Group includes all consolidated
subsidiaries.

     The tax effects of temporary differences that give rise to Federal
deferred tax assets and deferred tax liabilities at December 31, 1996 and 1995
were as follows:

</TABLE>

     A valuation allowance in the amount of $775,000 was established in 1994
due to the uncertainty associated with the realization of the gross deferred
tax asset.  In 1996, the Company utilized the balance of its NOL carryforward.
Management believes that it is more likely than not that the net deferred
Federal tax asset is realizable and therefore, has not provided for any
valuation allowance at December 31, 1996.

</TABLE>

     The development of prior year incurred losses during 1995 was primarily
attributable to the loss development from Northridge Earthquake.

     During 1996, 1995 and 1994, the Insurance Companies paid a gross amount of
$2,794,000, $2,251,000 and $181,000, respectively, and a net amount of
$425,000, $117,000 and $83,000, respectively for environmental pollution and
asbestos related claims.  As of December 31, 1996 and 1995, the Insurance
Companies carried a gross reserves of $5,421,000 and $4,783,000, respectively,
and a net case reserve of $1,042,000 and $876,000, respectively, for the
potential exposure of the Insurance Companies to such claims.  For the year
ended December 31, 1996 and 1995, open claims with environmental pollution and
asbestos exposure amounted to 2,024 and 1,594, respectively.  Management
believes that its reserves for such claims are adequate, because the Insurance
Companies participation in such risks was generally in the higher excess layers
and, based on a continuing review of such claims, management believes that a
majority of these claims will be unlikely to penetrate such high excess layers
of coverage; however, due to the significant assumptions inherent in estimating
these exposures, actual liabilities could differ from current estimates.

     Ceded losses and loss adjustment expenses incurred were $61,964,370,
$43,551,046 and $158,225,000 in 1996, 1995, and 1994, respectively.

     A contingent liability exists with respect to reinsurance ceded, since the
Insurance Companies would be required to pay losses in the event the assuming
reinsurers are unable to meet their obligations under their reinsurance
agreements with the Insurance Companies.

     At December 31, 1996 the Company had reinsurance receivables from the
following five reinsurers which are in excess of 5% of the insurance companies
surplus:  Underwriters at Lloyds, $27,143,000; SCOR Reinsurance Company,
$7,701,000; Chiyoda Fire and Marine Insurance, $7,372,000; Insurance
Corporation of New York, $7,105,000; Frankona Ruckversicherungs A.G,
$5,029,000.

The Company's reinsurance security committee continually monitors the financial
strength of its reinsurers and the amounts of reinsurance receivables from
those reinsurers.  An allowance is established to the extent that it is
determined that the ultimate amount collectible is less than the amount
recorded as a receivable.  At December 31, 1996 and 1995, an allowance for
uncollectible reinsurance of $800,000 was recorded.  The expense recorded for
uncollectible reinsurance was $0, $688,000 and $1,209,000 for 1996, 1995 and
1994, respectively.

THE NAVIGATORS GROUP, INC. AND SUBSIDIARIES
NOTES TO CONSOLIDATED FINANCIAL STATEMENTS (CONTINUED)

     The carrying amounts shown in the table are included in the Consolidated
Balance Sheets under the indicated captions.

     The carrying amounts of cash and premium receivables approximate fair
value because of the short maturity of those instruments.  The fair values of
debt securities and equity investments are based on quoted market prices at the
reporting date for those or similar investments.

     Included within commissions receivable is contingent commissions
receivable which is billed by the Somerset Companies to participants of the
insurance pools two calendar years subsequent to a given underwriting year and,
as a result, fair value is less than carrying value.  Fair value of contingent
commissions receivable is estimated based on the present value of anticipated
cash flows based on interest rates of debt instruments with similar maturities.

     The fair value of the Company's loans payable to banks approximates
carrying value since the interest rate charged is computed using market rates.

NOTE 11. --STOCK OPTION PLANS

     The Company has an Incentive Stock Option Plan and a Non Qualified Stock
Option Plan which allow for the grant to key employees of the Group, its
subsidiaries and affiliates, of options to purchase an aggregate of 900,000
shares of common stock.  Under the Non Qualified Stock Option Plan, stock
appreciation rights may also be granted.

     All options are granted at exercise prices which approximate the fair
market value of the common stock on the date of the grant.  No amounts are
charged to expense upon the granting of options under the plans.

     Common stock options outstanding at December 31, consisted of the

     The Company granted 166,000 and 111,500 stock appreciation rights at $17,
the approximate fair market value of the common stock on the date of the grant
in 1996 and 1995, receptively.  The amounts charged to expense in 1996 and 1995
were $45,586 and $0 respectively.

     Effective January 1, 1996, the Company adopted the provisions of SFAS 123
"Accounting for Stock Based Compensation" which requires the Company to either
record compensation expense or provide additional disclosures with respect to
stock awards and stock option grants made after December 31, 1994.  As
permitted under the statement, the company continued to apply the provisions of
APB Opinion No. 25 "Accounting for Stock issued to Employees."  Had
compensation expense for the Company stock option awards been determined in
accordance with SFAS 123, the effect on the Company's 1996 and 1995 net
earnings would not have been material.

                                                       EXHIBIT  10-7

                                                       July 30, 1996

Mr. Michael J. Abdallah
48 Ince Road
Burwood Park
Walton on Thames
Surrey KT 125BJ
England

Dear Mike:

This letter confirms our agreement to the terms and conditions applying to your
employment as President of the Somerset Companies.

I.   RESPONSIBILITY

  You will have the responsibility for the Group's worldwide Marine, Aviation,
  Offshore and Onshore Energy and related activities, which currently account
  for approximately eighty percent of our existing insurance and reinsurance
  business.  You will be expected to report directly to me.  You will also be
  responsible for our London and International operations, as well as having
  joint responsibility (as part of the Senior Management Team) for managing
  outwards reinsurance for the Group.

II.  COMPENSATION AND BENEFITS

  A. Your base salary will be $250,000 per annum.

  B.   As a member of the executive committee, you will participate in our
       executive incentive bonus program, based upon an earnings formula, where
       you can earn up to a further one hundred percent of your base salary.

       Insofar as we are halfway through the year, we have agreed we will pay
       you a flat $125,000 bonus for 1996 and then for future years you will be
       on the same formula basis as the rest of the staff.  These bonuses are
       generally paid in March, once the results are finalized.

  C.   To compensate you for the loss of bonus from CIGNA, which you have
       told me was $55,000 after tax last year, we will pay you a one time sum
       of $80,000.

  D.   You will receive twenty working days vacation each year.

III. MONEY PURCHASE PLAN

  You will participate in the Company's Money Purchase Plan which is invested
  on a tax deferred basis for you.  Please refer to the Employee Manual for
  more details on how the plan works and for the many other benefits provided
  by the Company.

  In addition, in the event of your termination prior to your being fully
  vested, we will pay you a bonus equivalent to the difference between the
  amount vested and the fully vested amount at that point in time.

IV.  STOCK OPTIONS

  The company has an stock option program and as an incentive to you, you will
  be granted 50,000 options, or warrants, on Navigators' stock.  Depending on
  your performance, and the company's results, you can expect to receive
  further options as circumstances permit.

  As a general rule, these "options" have been granted at a price approximately
  10% below the market price at the time of the grant.

V.   MOVING EXPENSES

  A.   The Company will provide you and your family with business class
       airfare and reimburse your travel expenses for your relocation to the
       United States.  It is understood that, insofar as for the first few
       months you wish to rent a house before deciding to purchase one, we will
       likely be picking up moving costs twice.  For a period of up to two
       months, while you search for your rental accommodation, we will
       reimburse you for reasonable temporary hotel accommodation.

       When you decide to purchase your first house, we will reimburse you for
       the reasonable closing costs and lawyers fees.

  B.   The Company will pay for packing and shipping your household and
       personal effects, furniture and furnishings to the United States.

  C.   To help you and your family assimilate into a new community and
       culture, until the end of 1998, the Company will assist you with the
       expenses of domestic help.

VI.  EMERGENCY HOME LEAVE

   In the event of a death or serious illness of a member of your or your
   spouse's immediate family, or other personal emergency requiring your and
   your spouse's presence in Sydney, Australia, emergency leave and
   transportation expenses will be provided.

VII. TAX RETURN PREPARATION

  The Company's accounting firm will assist you in the preparation and filing
  of your United States, U.K., and Australian income tax returns.  The fees for
  this service will be paid by the Company.

VIII. TERMINATION

  Your employment will be continuous subject to six months prior written notice
  by either party of termination, except for reasons of sexual harassment or
  suspected dishonesty. We further both agree, except for the aforementioned
  reasons, that no notice will be given prior to January 1, 1999, unless, you
  decide to leave the company, against our wishes but for your own family
  reasons.  If this occurs before January 1, 1999, we will pay you three months
  salary to help you get relocated back to Sydney, Australia.

IX.  RELOCATION COSTS

  In the event of termination of your employment, either at your own, or the
  Company's initiative, the Company will pay for moving you, your family, and
  your household goods back to Sydney, Australia subject to a maximum of
  $50,000.  These expenses will be paid providing that you return to your home
  Country within 30 days of termination and do not accept other employment in
  the insurance business within a six month period.


If you find these terms satisfactory, would you please sign and return a Copy
of this letter to me, retaining the Original for your own records.


Sincerely,

                       ARTICLE II. REVOLVING CREDIT LOANS

                  Section 2.01. Revolving Credit. The Borrower and each Lender
acknowledge that as of the opening of business on the Second Closing Date there
are outstanding Existing Revolving Credit Loans in the amount of Two Million
Dollars ($2,000,000) and Existing Term Loans in the amount of Fifteen Million
Dollars ($15,000,000). The Borrower and the Lenders agree that on the Second
Closing Date the Existing Revolving Credit Loan will continue as Revolving
Credit Loans under this Agreement and the Existing Term Loans will be converted
into Revolving Credit Loans under this Agreement.

                  Subject to the terms and conditions of this Agreement, each of
the Lenders severally agrees to make loans (the "Revolving Credit Loans") pro
rata according to each such Lender's Pro Rata Share of the Revolving Credit
Commitment, to the Borrower from time to time during the period from the Second
Closing Date up to but not including the Revolving Credit Termination Date,
provided that the aggregate principal amount of all Revolving Credit Loans
outstanding at any time does not exceed the then effective Revolving Credit
Commitment. Each Revolving Credit Loan which shall not utilize the Revolving
Credit Commitment in full shall be in the minimum amount set forth in Section
2.11. Within the limits of the Revolving Credit Commitment, the Borrower may
borrow, make an optional prepayment pursuant to Section 2.08, and reborrow under
this Section 2.01.

                  The failure of any Lender to make any requested Revolving
Credit Loan to be made by it on the date specified for such Revolving Credit
Loan shall not relieve any other Lender of its obligation (if any) to make its
Pro Rata Share of such Revolving Credit Loan on such date, but no Lender shall
be responsible for the failure of any other Lender to make such Revolving Credit
Loans to be made by such other Lender.

                  Section 2.02. Notice and Manner of Borrowing. The Borrower
shall give the Agent at least three (3) Business Days' written or telegraphic or
facsimile notice (effective upon receipt) of any Revolving Credit Loan to which
the LIBOR Interest Rate applies. The Borrower shall give the Agent written or
telegraphic or facsimile notice (effective upon receipt) of any Revolving Credit
Loan to which the Base Rate applies by not later than 10:00 A.M. (New York time)
one (1) Business Day before the date of such Loan. Each of the foregoing notices
(a "Borrowing Notice") must specify: (1) the date and the amount of such
Revolving Credit Loan; (2) either that the Revolving Credit Loan will bear
interest at (a) the 


                                       23
<PAGE>   30


Base Rate or (b) the LIBOR Interest Rate plus the Applicable Margin; and (3) in
the case of a LIBOR Loan, the initial Interest Period applicable thereto. The
Agent will promptly notify each Lender of receipt by the Agent of a Borrowing
Notice and of the contents thereof. Not later than 10:00 A.M. (New York time) on
the date of a LIBOR Loan and 2:00 P.M. (New York time) on the date of a Base
Rate Loan, each Lender will make available to the Agent at the Head Office in
immediately available funds such Lender's Pro Rata Share of such Loan. After the
Agent's receipt of such funds, not later than noon (New York time) on the date
of a LIBOR Loan and 3:00 P.M. (New York time) on the date of a Base Rate Loan,
and upon fulfillment of the applicable conditions set forth in Article V the
Agent will make such Revolving Credit Loan available to Borrower in immediately
available funds by crediting the amount thereof to Borrower's account with the
Agent.

                  Section 2.03. Non-Receipt of Funds by the Agent. Unless the
Agent shall have received notice from a Lender prior to the date on which such
Lender is to provide funds to the Agent for a Revolving Credit Loan to be made
by such Lender that such Lender will not make available to the Agent such funds,
the Agent may assume that such Lender has made such funds available to the Agent
on the date of such Revolving Credit Loan and the Agent, in its sole discretion,
may, but shall not be obligated to, in reliance upon such assumption, make
available to the Borrower on such date a corresponding amount. If and to the
extent such Lender shall not have made such funds available to the Agent, such
Lender agrees to repay the Agent forthwith on demand such corresponding amount
together with interest thereon, for each day from the date such amount is made
available to the Borrower until the date such amount is repaid to the Agent, at
the Federal Funds Rate. If such Lender shall repay to the Agent such
corresponding amount, such amount so repaid shall constitute such Lender's
Revolving Credit Loan for purposes of this Agreement. If such Lender does not
pay such corresponding amount forthwith upon the Agent's demand therefor, the
Agent shall promptly notify the Borrower, and the Borrower shall immediately pay
such corresponding amount to the Agent with the interest thereon, for each day
from the date such amount is made available to the Borrower until the date such
amount is repaid to the Agent, at the rate of interest applicable at the time to
such proposed Revolving Credit Loan.

                  Unless the Agent shall have received notice from the Borrower
prior to the date on which any payment is due to any Lender hereunder that the
Borrower will not make any payment in full, the Agent may assume that the
Borrower has made such payment in full to the Agent on such date and the Agent,
in its sole discretion, may, but shall not be obligated to, in reliance upon
such assumption, cause to be distributed to each Lender on such due date an
amount equal to the amount then due


                                       24
<PAGE>   31


such Lender. If and to the extent the Borrower shall not have so made such
payment in full to the Agent, each Lender shall repay to the Agent forthwith on
demand such amount distributed to such Lender together with interest thereon,
for each day from the date such amounts are distributed to such Lender until the
date such Lender repays such amount to the Agent, at the Federal Funds Rate.

                  Section 2.04. Interest. The Borrower shall pay interest to the
Agent for the account of the Lenders on the outstanding and unpaid principal
amount of the Revolving Credit Loan at a rate per annum as follows: (1) for a
Base Rate Loan at a rate equal to the Base Rate; and (2) for a LIBOR Loan at a
rate equal to the LIBOR Interest Rate plus the Applicable Margin. Any principal
amount and any interest not paid when due (at maturity, by acceleration or
otherwise) shall bear interest thereafter, payable on demand, at the Default
Rate.

                  The interest rate on each Base Rate Loan shall change when the
Base Rate changes. Interest on each Revolving Credit Loan shall not exceed the
maximum amount permitted under applicable Law and shall be calculated on the
basis of a year of three hundred sixty (360) days for the actual number of days
elapsed.

                  Accrued interest on each Base Rate Loan shall be due and
payable on each Monthly Date in arrears. Accrued interest on each LIBOR Loan
shall be due and payable on the last day of the Interest Period for such Loan,
and, in the case of an Interest Period greater than three (3) months, at three
(3) month intervals after the first day of such Interest Period. Interest
accruing at the Default Rate shall be due and payable on demand.

                  LIBOR Loans shall be in minimum amounts of One Million Dollars
($1,000,000) and incremental multiples of Two Hundred Fifty Thousand Dollars
($250,000).

                  Section 2.05. Interest Periods; Conversions; Renewals. In the
case of each LIBOR Loan, the Borrower shall select an Interest Period of any
duration which is in accordance with the definition of "Interest Period" in
Section 1.01, subject to the following limitations; (1) no Interest Period may
extend beyond the Revolving Credit Termination Date; (2) no Interest Period
shall have a duration of less than one month, and if any such proposed Interest
Period would otherwise be for a shorter period, such Interest Period shall not
be available; and (3) if an Interest Period would end on a day which is not a
Business Day, such Interest Period shall be extended to the next Business Day.

                  The Borrower may elect from time to time to convert all or a
part of one type of Revolving Credit Loan into another



                                       25
<PAGE>   32


type of Revolving Credit Loan or to renew all or part of a Revolving Credit Loan
by giving the Agent notice at least one (1) Business Day before conversion into
a Base Rate Loan, and at least three (3) Business Days before the conversion
into or renewal of a LIBOR Loan, specifying (1) the renewal or conversion date;
(2) the amount of the Revolving Credit Loan to be converted or renewed; and (3)
in the case of renewals of or a conversion into LIBOR Loans, the duration of the
Interest Period applicable thereto; provided, that LIBOR Loans can be converted
only on the last day of the Interest Period for such Loan. All notices given
under this Section 2.05 shall be irrevocable and shall be given not later than
11:00 a.m., New York time, on the day which is not less than the number of
Business Days specified above for such notice. If the Borrower shall fail to
give the Agent the notice as specified above for the renewal of a LIBOR Loan
prior to the end of the Interest Period with respect thereto, such LIBOR Loan
shall automatically be converted into a Base Rate Loan on the last day of the
Interest Period for such Loan. The Borrower agrees that no more than five (5)
Interest Periods can be in effect at any one time.

                  Section 2.06. Fees. The Borrower agrees to pay to the Agent
for the account of the Lenders on the Second Closing Date all Commitment Fees
(as defined in the 1994 Credit Agreement) accrued and unpaid as of the Second
Closing Date. Upon receipt of such Commitment Fees the Agent will promptly
thereafter cause to be distributed to the Lenders their respective Pro Rata
Share of such Commitment Fees.

                  The Borrower agrees to pay to the Agent for the account of the
Lenders a commitment fee on the average daily difference between (1) the sum of
(a) the Revolving Credit Commitment plus (b) the Letter of Credit Commitment and
(2) the sum of (a) the aggregate outstanding principal amount of all Revolving
Credit Loans plus (b) the aggregate undrawn face amount of all Letters of
Credit, at the rate of fifteen hundredths of one percent (0.15%) per annum,
based on a year of three hundred sixty (360) days, payable in arrears on each
Quarterly Date during the period from the Second Closing Date to the Revolving
Credit Termination Date, commencing September 30, 1996, and ending on the
Revolving Credit Termination Date (the "Commitment Fee"). Upon receipt of any
such Commitment Fee the Agent will promptly thereafter cause to be distributed
to the Lenders their respective Pro Rata Share of such Commitment Fee.

                  The Borrower agrees to pay to the Agent on the Second Closing
Date for the account of the Lenders an amendment fee of One Hundred Twenty-Five
Thousand Dollars ($125,000) (the "Revolving Credit Amendment Fee"). Upon receipt
of such Amendment Fee the Agent will promptly thereafter cause to be


                                       26
<PAGE>   33


distributed to the Lenders their respective Pro Rata Share of such Amendment
Fee.

                  The Borrower agrees to pay to the Agent on or before the
Second Closing Date and on each anniversary of the Second Closing Date until the
payment in full of all Loans and the termination of all Commitments for the
account of the Agent a non-refundable agency fee of Forty Thousand Dollars
($40,000) (the "Agency Fee").

                  Section 2.07. Revolving Credit Notes. All Revolving Credit
Loans made by each Lender under this Agreement shall be evidenced by, and repaid
with interest in accordance with, a single amended and restated promissory note
of the Borrower for each Lender, each in substantially the form of Exhibit 2.07,
duly completed, in the principal amount equal to such Lender's Pro Rata Share of
the Revolving Credit Commitment, dated the Second Closing Date, payable to such
Lender and maturing as to principal on the Revolving Credit Termination Date
(the "Revolving Credit Notes"). Each Lender is hereby authorized by the Borrower
to endorse on the schedule attached to the Revolving Credit Note held by it the
amount of each Revolving Credit Loan, and each payment of principal amount
received by such Lender on account of the Revolving Credit Loans, which
endorsement shall, in the absence of manifest error, be conclusive as to the
outstanding balance of the Revolving Credit Loans made by such Lender; provided,
however, that the failure to make such notation with respect to any Revolving
Credit Loan or payment shall not limit or otherwise affect the obligations of
the Borrower under this Agreement or the Revolving Credit Note held by such
Lender. Each Lender agrees that, prior to any assignment of the Revolving Credit
Note held by it, it will properly and completely endorse the schedule attached
to such Revolving Credit Note.

                  Section 2.08. Prepayments. The Borrower may, upon at least one
(1) Business Day's notice to the Lenders in the case of Base Rate Loans, and at
least three (3) Business Days' notice to each Lender in the case of LIBOR Loans,
prepay the Revolving Credit Notes, in whole or in part with accrued interest to
the date of such prepayment on the amount prepaid; provided, that: (1) each
partial prepayment shall be in a principal amount of not less than Five Hundred
Thousand Dollars ($500,000); and (2) LIBOR Loans may be prepaid only on the last
day of the Interest Period for such Loan, unless the Borrower pays the Lenders
the Broken Funding Fee for such prepayment.

                  If at any time the aggregate principal amount of all
outstanding Revolving Credit Loans exceeds the then effective Revolving Credit
Commitment, then the Borrower shall immediately prepay the Revolving Credit
Loans in the amount of such excess.


                                       27
<PAGE>   34


                  Section 2.09. Method of Payment. The Borrower shall make each
payment under this Agreement and under the Revolving Credit Notes not later than
11:00 A.M. (New York time) on the date when due in Dollars to the Agent at the
Agent's Office in immediately available funds. The Agent will promptly
thereafter cause to be distributed to each Lender, to the extent of such payment
received from the Borrower, (1) such Lender's Pro Rata Share of the payments of
principal and interest in like funds, and (2) fees payable to such Lender in
accordance with the terms of this Agreement.

                  The Borrower hereby authorizes the Agent, if and to the extent
payment of the Revolving Credit Loans or interest thereon, or the Commitment Fee
or any other amount due by the Borrower to the Agent or any Lender under this
Agreement or under the Revolving Credit Notes or any other Loan Document, is not
made when due under this Agreement or under the Revolving Credit Notes or any
other Loan Document, to charge from time to time against any account it
maintains with the Agent or any Lender any such amount so due to the Agent
and/or the Lenders. The Agent will promptly thereafter cause to be distributed
to each Lender, to the extent of such payment (1) such Lender's Pro Rata Share
of the payments of principal and interest, and (2) fees payable to such Lender
in accordance with the terms of this Agreement.

                  Except to the extent provided in this Agreement, whenever any
payment to be made under this Agreement or under the Revolving Credit Notes
shall be stated to be due on any day other than a Business Day, such payment
shall be made on the next succeeding Business Day, and such extension of time
shall in such case be included in the computation of the payment of interest and
the Commitment Fee, and other fees, as the case may be.

                  Section 2.10. Use of Proceeds. The proceeds of the Revolving
Credit Loan shall be used by the Borrower for general corporate purposes. The
Borrower will not, directly or indirectly, use any part of such proceeds for the
purpose of purchasing or carrying any margin stock within the meaning of
Regulation G, T, U or X of the Board of Governors or to extend credit to any
Person for the purpose of purchasing or carrying any such margin stock.

                  Section 2.11. Minimum Amounts. The Revolving Credit Loans and
each conversion shall, in the case of Base Rate Loans, be in an amount at least
equal to One Hundred Thousand Dollars ($100,000) and in integral multiples of
One Hundred Thousand Dollars ($100,000) and in the case of LIBOR Loans, be in an
amount at least equal to One Million Dollars ($1,000,000) and in integral
multiples of Two Hundred Fifty Thousand Dollars ($250,000) (LIBOR Loans having
different Interest Periods at the same time hereunder to be deemed separate
Loans and


                                       28
<PAGE>   35


Conversions for purposes of the foregoing, one for each Interest Period).
Anything in this Agreement to the contrary notwithstanding, the aggregate
principal amount of LIBOR Loans having the same Interest Period shall be at
least equal to One Million Dollars ($1,000,000) and integral multiples thereof
of Two Hundred Fifty Thousand Dollars ($250,000) and, if any LIBOR Loan would
otherwise be in a lesser principal amount for any period, such LIBOR Loan shall
be a Base Rate Loan during such period.

                  Section 2.12. Additional Costs. The Borrower shall pay
directly to each Lender from time to time on demand such amounts as such Lender
may determine to be necessary to compensate it for any increased costs which
such Lender determines are attributable to its making or maintaining any LIBOR
Loan, or its obligation to convert any Base Rate Loan to a LIBOR Loan hereunder,
or any reduction in any amount receivable by such Lender hereunder in respect of
any of such LIBOR Loans or such obligation (such increases in costs and
reductions in amounts receivable being herein called "Additional Costs"),
resulting, in each case, from any Regulatory Change which:

                  (i) subjects such Lender to any tax of any kind whatsoever
         with respect to, or changes the basis of taxation of any amounts
         payable to such Lender under this Agreement or the Revolving Credit
         Note in respect of any of such LIBOR Loans (other than changes in the
         rate of taxes imposed on or measured by the overall net income of such
         Lender or of its Applicable Lending Office for any of such LIBOR Loans
         by the jurisdiction in which such Lender has its principal office or
         such Applicable Lending Office); or

                  (ii) (other than to the extent of the LIBOR Reserve
         Requirement, taken into account in determining the LIBOR Interest Rate
         at the commencement of the applicable Interest Period) imposes or
         modifies any reserve, special deposit, deposit insurance or assessment,
         minimum capital, capital ratio or similar requirements relating to any
         extensions of credit or other assets of, or any deposits with or other
         liabilities of, such Lender (including any LIBOR Loans, or any deposits
         referred to in the definition of "LIBOR Interest Rate" in Section
         1.01), or any commitment of the Lender; or

                  (a) imposes any other condition affecting this Agreement or
         the Revolving Credit Note (or any of such extensions of credit or
         liabilities).

                  Without limiting the effect of the provisions of the first
paragraph of this Section 2.12, in the event that, by reason of any Regulatory
Change, any Lender either (1) incurs


                                       29
<PAGE>   36


Additional Costs based on or measured by the excess above a specified level of
the amount of a category of deposits of other liabilities of such Lender which
includes deposits by reference to which the LIBOR Interest Rate is determined as
provided in this Agreement or a category of extensions of credit or other assets
of such Lender which includes loans based on the LIBOR Interest Rate or (2)
becomes subject to restrictions on the amount of such a category of liabilities
or assets which it may hold, then, if such Lender so elects by notice to the
Borrower, the obligation of such Lender to make or continue, or to convert Base
Rate Loans into LIBOR Loans shall be suspended until such Regulatory Change
ceases to be in effect (in which case the provisions of Section 2.15 shall be
applicable).

                  Without limiting the effect of the foregoing provisions of
this Section 2.12 (but without duplication), the Borrower shall pay directly to
each Lender from time to time on request such amounts as such Lender may
determine to be necessary to compensate such Lender for any costs which it
determines are attributable to the maintenance by such Lender (or any Applicable
Lending Office), pursuant to any law or regulation or any interpretation,
directive or request (whether or not having the force of law and whether in
effect on the date of this Agreement or thereafter) of any court or governmental
or monetary authority of capital in respect of the Revolving Credit Loan (such
compensation to include, without limitation, an amount equal to any reduction of
the rate of return on assets or equity of such Lender (or any Applicable Lending
Office) to a level below that which such Lender (or any Applicable Lending
Office) could have achieved but for such law, regulation, interpretation,
directive or request).

                  Determinations and allocations by such Lender for purposes of
this Section 2.12 of the effect of any Regulatory Change pursuant to the first
or second paragraph of this Section 2.12 or of the effect of capital maintained
pursuant to the third paragraph of this Section 2.12, on its costs or rate of
return of maintaining the Revolving Credit Loan or on amounts receivable by it
in respect of the Revolving Credit Loan, and the amounts required to compensate
such Lender under this Section 2.12, shall be conclusive absent manifest error.

                  Section 2.13. Limitation on Types of Loans. Anything herein to
the contrary notwithstanding, if, on or prior to the determination of the LIBOR
Interest Rate for any Interest Period the Required Lenders determine (which
determination shall be conclusive) that (1) the relevant rates of interest
referred to in the definition of "LIBOR Interest Rate" in Section 1.01 upon the
basis of which the rate of interest for LIBOR Loans for such Interest Period is
to be determined do not adequately cover the cost to the Lenders of making or
maintaining such LIBOR Loans for such Interest


                                       30
<PAGE>   37


Period; or (2) quotations of interest rates for the relevant deposits referred
to in the definition of LIBOR Interest Rate are not being provided in the
relevant amounts or for the relevant maturities for purposes of determining the
rate of interest on a LIBOR Loan as provided in this Agreement; then the Agent
shall give the Borrower prompt notice thereof, and so long as such condition
remains in effect, the Lenders shall be under no obligation to make LIBOR Loans,
convert Loans into LIBOR Loans, or continue LIBOR Loans, and the Borrower shall,
on the last day(s) of the then current Interest Period(s) for the outstanding
LIBOR Loans, either prepay such LIBOR Loans or convert such LIBOR Loans into
Base Rate Loans.

                  Section 2.14. Illegality. Notwithstanding any other provision
of this Agreement, in the event that it becomes unlawful for any Lender or its
Applicable Lending Office to honor its obligation to make or maintain LIBOR
Loans hereunder or convert Base Rate Loans into LIBOR Loans, then such Lender
shall promptly notify the Borrower thereof and such Lender's obligation to make
or continue LIBOR Loans shall be suspended until such time as such Lender may
again make and maintain LIBOR Loans (in which case the provisions of Section
2.15 shall be applicable); provided, however, that each Lender agrees to change
its Applicable Lending Office if the illegality referred to in this Section 2.14
can be cured by such a change without disadvantage or detriment to such Lender
(as determined in such Lender's sole discretion).

                  Section 2.15. Treatment of Affected Loans. If the obligations
of any Lender to make or continue LIBOR Loans, or to convert Base Rate Loans
into LIBOR Loans are suspended pursuant to Section 2.12, 2.13 or 2.14 (LIBOR
Loans so affected being herein called "Affected Loans") such Lender's Affected
Loans shall be automatically converted into Base Rate Loans on the last day(s)
of the then current Interest Period(s) for the Affected Loans (or, in the case
of a conversion required by Section 2.12, 2.13 or 2.14, on such earlier date as
such Lender may specify to the Borrower).

                  To the extent that such Lender's Affected Loans have been so
converted, all payments and prepayments of principal which would otherwise be
applied to such Lender's Affected Loans shall be applied instead to its Base
Rate Loans. All Loans which would otherwise be made or continued by such Lender
as LIBOR Loans shall be made or continued instead as Base Rate Loans and all
Base Rate Loans of such Lender which would otherwise be converted into LIBOR
Loans, shall remain as Base Rate Loans.

                  Section 2.16. Risk-Based Capital. With respect to LIBOR Loans,
in addition to the rights granted under any other provision of this Agreement,
in the event that any Lender determines that (1) compliance with any judicial,


                                       31
<PAGE>   38


administrative, or other governmental interpretation of any law or regulation or
(2) compliance by such Lender or any corporation controlling such Lender with
any guideline or request from any central bank or other Governmental Authority
(whether or not having the force of law) has the effect of requiring an increase
in the amount of capital required or expected to be maintained by such Lender or
any corporation controlling such Lender, and such Lender determines that such
increase is based upon its obligations hereunder, and other similar obligations,
the Borrower shall pay to such Lender such additional amount as shall be
certified by such Lender to be the amount allocable to such Lender's obligations
to the Borrower hereunder. Each Lender will notify the Borrower of any event
occurring after the date of this Agreement that will entitle such Lender to
compensation pursuant to this Section 2.16 as promptly as practicable after it
obtains knowledge thereof and determines to request such compensation.

                  Determinations by each Lender for purposes of this Section
2.16 of the effect of any increase in the amount of capital required to be
maintained by such Lender and of the amount allocable to such Lender's
obligations to the Borrower hereunder shall be conclusive, absent manifest
error.

                  Section 2.17. Certain Compensation. The Borrower shall pay to
the Agent for the account of the applicable Lender, upon the request of such
Lender through the Agent, such amount or amounts as shall be sufficient (in the
reasonable opinion of such Lender) to compensate it for any loss, cost or
expense which such Lender determines is attributable to:

                  (1) any payment, prepayment, conversion or continuation of a
         LIBOR Loan made by such Lender on a date other than the last day of an
         Interest Period for such Loan whether by reason of acceleration or
         otherwise; or

                  (2) any failure by the Borrower for any reason to borrow,
         convert or continue a LIBOR Loan to be borrowed, converted or continued
         by such Lender on the date specified therefor in the relevant notice
         issued by the Borrower.

                  Without limiting the foregoing, such compensation shall
include an amount equal to the Broken Funding Fee. A determination of any Lender
as to the amounts payable pursuant to this Section 2.17 shall be conclusive
absent manifest error.

                  Section 2.18. Capital Adequacy. Without duplication of the
requirements of Section 2.12, if any Lender shall have determined that, after
the date hereof, the adoption of any applicable law, rule or regulation
regarding capital adequacy, or any change therein, or any change in the
interpretation or administration thereof by any Governmental Authority, central


                                       32
<PAGE>   39


bank or comparable agency charged with the interpretation or administration
thereof, or any request or directive regarding capital adequacy (whether or not
having the force of law) of any such Governmental Authority, central bank or
comparable agency, has or would have the effect of reducing the rate of return
on capital of such Lender (or its Parent) as a consequence of such Lender's
obligations hereunder to a level below that which such Lender (or its Parent)
could have achieved but for such adoption, change, request or directive (taking
into consideration its policies with respect to capital adequacy) by an amount
deemed by such Lender to be material, then from time to time, within fifteen
(15) days after demand by such Lender (with a copy to the Agent), the Borrower
shall pay to such Lender such additional amount or amounts as will compensate
such Lender (or its Parent) for such reduction. A certificate of any Lender
claiming compensation under this Section 2.18, setting forth in reasonable
detail the basis therefor, shall be conclusive in the absence of manifest error.
The Borrower is only required to make payments under this Section 2.18 to the
Lender that requires the payment of such additional amount or amounts.

                  Section 2.19. Taxes. (a) All payments made by the Borrower
under this Agreement and the other Loan Documents shall be made free and clear
of, and without deduction or withholding for or on account of, any present or
future income, stamp or other taxes, levies, imposts, duties, charges, fees,
deductions or withholdings, now or hereafter imposed, levied, collected,
withheld or assessed by any Governmental Authority, excluding, in the case of
the Agent and each Lender, any net income taxes and franchise taxes (imposed in
lieu of net income taxes) imposed on the Agent or such Lender, as the case may
be, by the United States or any state, local or foreign taxing authority (all
such non-excluded taxes, levies, imposts, duties, charges, fees, deductions and
withholdings being hereinafter called "Taxes"). If any Taxes are required to be
withheld from any amounts payable to the Agent or any Lender hereunder or under
the other Loan Documents, the amounts so payable to the Agent or such Lender
shall be increased to the extent necessary to yield to the Agent or such Lender
(after payment of Taxes) interest or any such other amounts payable hereunder at
the rates or in the amounts specified in this Agreement and the other Loan
Documents. Whenever any Taxes are payable by the Borrower, as promptly as
possible thereafter the Borrower shall send to the Agent or such Lender, as the
case may be, a certified copy of an original official receipt received by the
Borrower showing payment thereof. If the Borrower fails to pay any Taxes when
due to the appropriate taxing authority or fails to remit to the Agent or such
Lender, as the case may be, the required receipts or other required documentary
evidence, the Borrower shall indemnify the Agent and such Lender for any
incremental taxes, interest or


                                       33
<PAGE>   40


penalties that may become payable by the Agent or such Lender as a result of any
such failure.

                  (b) Each Lender represents to the Borrower and the Agent that
it is entitled to receive any payments to be made to it hereunder without the
withholding of any tax and will furnish to the Agent such forms, certifications,
statements and other documents as the Agent may reasonably request from time to
time to evidence such Lender's exemption from the withholding of any tax imposed
by any jurisdiction or to enable the Agent to comply with any applicable laws or
regulations relating thereto. Without limiting the effect of the foregoing, if
any Lender is not created or organized under the laws of the United States or
any state thereof, such Lender will furnish to the Agent Form 4224 or Form 1001
of the Internal Revenue Service, or such other forms, certifications, statements
or documents, duly executed and completed by such Lender as evidence of such
Lender's exemption from the withholding of U.S. tax with respect thereto. The
Agent shall not be obligated to make any payments hereunder to such Lender in
respect of any Loan or such Lender's Revolving Credit Commitment until such
Lender shall have furnished to the Agent the requested form, certification,
statement or document.


                         ARTICLE III. LETTERS OF CREDIT

                  Section 3.01. Letters of Credit. BBH&Co. has issued an
irrevocable standby letter of credit dated December 14, 1993 for the benefit of
Society of Lloyd's in the amount of Two Million Five Hundred Eighty-Five
Thousand Pounds ((pound)2,585,000) (as amended, the "BBH&Co. Letter of Credit")
for the account of the Borrower. Within sixty (60) days from the Second Closing
Date, the Issuing Bank shall issue for the benefit of the Society of Lloyd's a
replacement letter of credit for the BBH&Co. Letter of Credit (the "Replacement
Letter of Credit").

                  In addition to the Replacement Letter of Credit, subject to
the approval of all the Lenders as set forth below, the Issuing Bank agrees, on
the terms and conditions hereinafter set forth, to issue standby letters of
credit for the account of the Borrower to support NCUL's obligations with
respect to specific syndicates at the Society of Lloyd's (all such letters of
credit together with the Replacement Letter of Credit, the "Letters of Credit"),
from time to time during the period from the Second Closing Date to the Letter
of Credit Termination Date, provided that at the time of the issuance of such
Letter of Credit the aggregate face amount of all outstanding Letter of Credit
Obligations does not exceed at any time Thirty Million Dollars ($30,000,000)
(the "Letter of Credit Commitment"). The Issuing Bank will not be required to
issue a Letter of Credit with a maturity date more than five (5) years from the
date of issuance of such Standby Letter of 


                                       34
<PAGE>   41


Credit. In addition, the Issuing Bank will not issue a Letter of Credit unless
all Lenders in their sole discretion approve the issuance of the proposed Letter
of Credit to support such obligation to such syndicate. The Borrower agrees that
after a Letter of Credit is issued to support an obligation to a specific
syndicate the Borrower will not change the syndicate receiving the benefit of
such Letter of Credit without the consent of all the Lenders.

                  Notwithstanding the foregoing, with the consent of all the
Lenders the Letter of Credit Termination Date can be extended beyond January 2,
1998 and the maturity date of any Letter of Credit can be extended beyond
December 31, 2002.

                  In addition to the requirements noted above, the Issuing Bank
will not be required to issue a Letter of Credit unless the Borrower submits to
the Issuing Bank a Request for Letter of Credit at least two (2) Business Days
before the requested date to issue such Letter of Credit. Each Letter of Credit
will be subject to the terms and provisions of this Agreement, including but not
limited to those set forth in this Article III.

                  For purposes of determining usage and availability under this
Section 3.01 when a Letter of Credit is issued in Pounds, such Pounds will be
converted to Dollars upon issuance, and at the end of each calendar quarter, and
at any time thereafter as requested by the Agent or any Lender or the Issuing
Bank and such determination shall be made by the Agent in its sole determination
based upon the spot exchange rate between Dollars and Pounds as quoted by the
Agent's foreign exchange desk as of such date of determination. Notwithstanding
any other provisions of this Agreement, if at any time, after giving effect to
the conversion of pounds into Dollars as set forth above, the aggregate face
amount of all outstanding Letters of Credit is greater than Thirty Million
Dollars ($30,000,000) ("Conversion Differential") then Borrower must prepay the
Revolving Credit Loans to the extent required so that the difference between the
then effective Revolving Credit Commitment and the aggregate principal amount of
all outstanding Revolving Credit Loans is equal to or greater than the
Conversion Differential and, in the event the Conversion Differential exceeds
the then effective Revolving Credit Commitment, then the Borrower will provide
Cash Collateral in the amount of such difference.

                  On December 31, 2001 the Borrower agrees to provide Cash
Collateral to the Agent for the benefit of the Issuing Bank and the Lenders in
an amount equal to Fifteen Million Dollars ($15,000,000).

                  Section 3.02. Reimbursement Obligation. The Borrower will pay
the Issuing Bank, on demand at the Issuing


                                       35
<PAGE>   42

Bank's Principal Office, in immediately available funds, the amount required to
reimburse the Issuing Bank in respect of the Issuing Bank's payment of each
Instrument. Such reimbursement shall be made with interest from the date of the
Issuing Bank's payment of such Instrument to the date which is two (2) Business
Days after the date of such demand at the Base Rate, and thereafter at the
Default Rate until the date of reimbursement. Such reimbursement shall be in
Dollars at the Issuing Bank's selling rate for cable transfers to the place of
payment of the Instrument current on the date of payment or of the Issuing
Bank's settlement of its obligation, as the Issuing Bank may require or, at the
Issuing Bank's election, in the currency in which the Issuing Bank was required
to pay such Instrument. If, for any cause, on the date of payment or settlement,
as the case may be, there is no selling rate or other rate of exchange generally
current in New York for effecting such transfers, the Borrower will pay the
Issuing Bank on demand an amount in Dollars equivalent to the Issuing Bank's
actual cost of settlement of its obligation however or whenever the Issuing Bank
shall make such settlement, with interest at the Base Rate for Base Rate Loans
from the date of settlement to the date of payment. The Borrower will comply
with all governmental exchange regulations now or hereafter applicable to each
Letter of Credit or Instrument or payments related thereto and will pay the
Issuing Bank, on demand, in Dollars, such amount as the Issuing Bank may be or
may have been required to expend on account of such regulations. The Issuing
Bank may debit or direct any other Lender to debit any account or accounts
maintained by the Borrower with any office of the Issuing Bank or any other
Lender or any of their respective Subsidiaries or Affiliates (now or in the
future) and apply the proceeds to the payment of any and all amounts owed by the
Borrower to the Issuing Bank hereunder, and such Lender, Subsidiary or Affiliate
shall be authorized to act in accordance herewith and shall treat this
authorization as irrevocable. If the due date for reimbursement by the Borrower
pursuant to this Section 3.02 shall be extended by operation of Law or
otherwise, interest shall continue to accrue and be payable at the applicable
rate set forth in this Section 3.02.

                  Section 3.03. Payment of Commissions, Expenses and Interest.
The Borrower will pay the Issuing Bank, on demand, the Issuing Bank's commission
and all charges, costs, and expenses paid or incurred by the Issuing Bank in
connection with any Letter of Credit, and interest where chargeable, including
fees and charges of counsel and costs allocated by the Issuing Bank's internal
legal department in connection with the preparation, performance, or enforcement
of this Agreement or any Letter of Credit. Unless otherwise agreed:

                  (a)  administrative fees payable hereunder shall be
at the rate customarily charged by the Issuing Bank at the time
in like circumstances;


                                       36
<PAGE>   43


                  (b) interest payable under this Article III on amounts not
paid when due shall be at the lesser of (A) the maximum rate permissible under
applicable law or (B) the Base Rate; and

                  (c) in addition to commissions, fees and amounts otherwise
payable with respect to the issuance of a Letter of Credit, the Borrower shall
pay to the Issuing Bank on demand such amounts as the Issuing Bank in its sole
discretion determines are necessary to compensate it for any cost attributable
to its issuing or having outstanding such Letter of Credit resulting from the
application of any Law or regulation applicable to the Issuing Bank regarding
any reserve, assessment, capital adequacy or similar requirements relating to
letters of credit or the reimbursement agreements with respect thereto or to
similar liabilities or assets of the Issuing Bank whether existing at the time
of issuance of the Letter of Credit or adopted thereafter; including, without
limitation, to those related to or as a result of the sale of a Participation
under Section 4.02 hereof. The Borrower acknowledges that there may be various
methods of allocating costs to the Letter of Credit and agrees that the Issuing
Bank's allocation for purposes of determining the costs referred to above shall
be conclusive and binding upon the Borrower.

                  The Borrower shall pay to the Agent for the account of the
Issuing Bank on each Semi-Annual Date a fee in the amount of one-half of one
percent (1/2%) of the aggregate undrawn face amount of all Letters of Credit as
of such Semi-Annual Date, provided, however, upon the occurrence and during the
continuance of a Default or Event of Default the fee specified in this sentence
will be increased to an annual fee of two and one-half percent (2.5%) (the
"Letter of Credit Fee"). The Agent will remit their respective portions of such
Letter of Credit Fee to the Issuing Bank and each of the Lenders in accordance
with the provisions of Section 4.03 "Participation in Fees and Collateral;
Relationship".

                  Section 3.04. Proper Drawing; the Issuing Bank's Honoring. The
Issuing Bank may accept or pay any Instrument presented to it on or before the
expiration date set forth in a Letter of Credit. In addition:

                  (a) the Issuing Bank may honor the related Instrument(s) in an
amount or amounts not exceeding the amount of such Letter of Credit, and

                  (b) the Issuing Bank may honor, as complying with the terms of
such Letter of Credit, any Instrument or other document otherwise in order,
signed or issued by a person purporting to be an administrator, executor,
trustee in bankruptcy, debtor in possession, assignee for the benefit of


                                       37
<PAGE>   44


creditors, liquidator, receiver or other legal representative of the party
authorized under such Letter of Credit to draw or issue such Instruments or
other documents, regardless of any notice or information to the contrary.

                  Section 3.05. Amendment, Change, Modification; No Waiver. In
the event of any amendment, change or modification relating to a Letter of
Credit or any Instruments or documents called for thereunder, including waiver
of noncompliance of any such Instruments or documents with such terms of the
Letter of Credit, this Agreement shall be binding upon the Borrower with regard
to such Letter of Credit as so amended, changed, or modified, and to any action
taken by the Issuing Bank or any of its correspondents reacting thereto. No
amendment, change, waiver or modification to which the Issuing Bank has
consented shall be deemed to mean that the Issuing Bank will consent or has
consented to any other or subsequent request to amend, change, modify or waive a
term of such Letter of Credit. The Issuing Bank shall not be deemed to have
waived any of its rights hereunder, unless the Issuing Bank or its authorized
agent shall have signed such waiver in writing. No such waiver, unless expressly
stated therein, shall be effective as to any transaction which occurs subsequent
to the date of such waiver, nor as to any continuance of a breach after such
waiver.

                  Section 3.06. U.C.P.; Agreements and Acknowledgements;
Indemnifications. The Uniform Customs and Practices shall be binding on the
Borrower and the Issuing Bank, except to the extent it is otherwise expressly
agreed. The Borrower and the Issuing Bank also agree that:

                  (a) user(s) of a Letter of Credit shall not be deemed agents
of the Issuing Bank;

                  (b) none of the Issuing Bank, its Affiliates, Subsidiaries, or
its correspondents shall be responsible for:

                    (i) failure of any Instrument to bear any reference to the
         related Letter of Credit or inadequate reference in any Instrument to
         such Letter of Credit, or failure of any document (other than documents
         expressly required to be presented under such Letter of Credit) to
         accompany any Instrument at negotiation, or failure of any person to
         note the amount of any Instrument on the reverse of the Letter of
         Credit, or to surrender or take up the Letter of Credit or to forward
         documents apart from Instruments as required by the terms of such
         Letter of Credit, each of which provisions, if contained in a Letter of
         Credit itself, it is agreed may be waived by the Issuing Bank;


                                       38
<PAGE>   45


                   (ii) the validity, sufficiency or genuineness of any
         Instrument, even if such instrument shall in fact prove to be invalid,
         insufficient, fraudulent or forged;

                  (iii) errors, omissions, interruptions or delays in
         transmission, or delivery of any message, by mail, telex, cable,
         telegraph, wireless or other teletransmission or by oral instructions,
         whether or not they may be in cipher; or

                   (iv) any failure or inability of the Issuing Bank or anyone
         else to perform in accordance with the terms of the Letter of Credit by
         reason of any control or restriction rightfully or wrongfully exercised
         by any de facto or de jure Governmental Authority, or for any
         consequences arising from causes beyond the control of the Issuing Bank
         or its correspondents;

                  (c) the Issuing Bank shall not be responsible for any act,
error, neglect or default, omission, insolvency or failure in business of any of
its correspondents;

                  (d) the occurrence of any one or more of the contingencies or
events referred to in the Uniform Customs and Practices or in the preceding
subsections (b) and (c) shall not affect, impair, or prevent the vesting of any
of the Issuing Bank's rights or powers hereunder or the Borrower's obligation to
make payment;

                  (e)  the Borrower will promptly examine:

                    (i) any copy of a Letter of Credit (and of any amendments
          thereof) sent to it by the Issuing Bank; and

                    (ii) all Instruments and documents delivered to it from time
          to time, and, in the event of any claim of noncompliance with the
          Borrower's Instructions or other irregularity, the Borrower will
          immediately notify the Issuing Bank thereof in writing, the Borrower
          being conclusively deemed to have waived any such claim against the
          Issuing Bank and its correspondents unless such notice is given as
          aforesaid;

                  (f) any action, inaction or omission on the part of the
Issuing Bank or any of its correspondents, under or in connection with the
Letter of Credit or the related Instruments, documents or property, if in good
faith, shall be binding upon the Borrower and shall not place the Issuing Bank
or any of its correspondents under any liability to the Borrower.

                  The Borrower agrees to hold the Issuing Bank, each Affiliate
and Subsidiary of the Issuing Bank, its 


                                       39
<PAGE>   46


correspondents and each Participating Lender indemnified and harmless against
any and all claims, loss, liability or damage, including reasonable counsel
fees, howsoever arising from or in connection with any Letter of Credit,
including, without limitation, any such claim, loss, liability or damage arising
out of any transfer, sale, delivery, surrender or endorsement of any document at
any time(s) held by the Issuing Bank, any of its Affiliates or Subsidiaries or
any Participating Lender, or held for the account of any one of them by any
correspondent of any of them, or arising out of any action for injunctive or
other judicial or administrative relief arising out of or in connection with any
Letter of Credit and affecting, directly or indirectly, the Issuing Bank, such
Affiliate or Subsidiary or any Participating Lender, or arising out of any bond
or undertaking into which the Issuing Bank or its correspondents may be required
to enter; provided, that the Borrower shall not be required to indemnify any
such party to the extent that the Borrower proves that such claims, loss,
liability or damage of such party was caused by such party's willful misconduct
or gross negligence.

                  Section 3.07. Continuing Rights and Obligations. The Issuing
Bank's rights hereunder shall continue unimpaired, and the Borrower shall be and
remain obligated in accordance with the terms and provisions hereof,
notwithstanding the release and/or substitution of any property which may be
held as Collateral at any time(s), or of any rights or interest therein. No
delay, extension of time, renewal, compromise or other indulgence which may
occur or be granted by the Issuing Bank shall impair the Issuing Bank's rights
or powers hereunder.

                  Section 3.08. Instructions; No Liability. Instructions may be
honored by the Issuing Bank when received from anyone purporting to be an
Authorized Person. The Borrower may furnish the Issuing Bank with written
confirmation of any such Instruction, but the Issuing Bank's responsibility with
respect to any Instruction shall not be affected by its failure to receive or
the content of such confirmation. The Issuing Bank shall have no responsibility
to notify the Borrower of any discrepancies between the Borrower's Instructions
and its written confirmation, and in the event of any such discrepancy, the
original Instruction shall govern. The Issuing Bank shall be fully protected in,
and shall incur no liability to the Borrower for, acting upon any Instructions
or any oral, written, telephone, teleprocess, electronic, or other amendments
thereto which the Issuing Bank in good faith believes to have been given by any
Authorized Person, and in no event shall the Issuing Bank be liable for special,
consequential, or punitive damages. The Issuing Bank may, at its option, use any
means of verifying any Instruction received by it. The Issuing Bank also may, at
its option, refuse to act upon any Instruction or other communication or any
part


                                       40
<PAGE>   47


thereof, without incurring any responsibility for any loss, liability or expense
arising out of such refusal. All such authorizations and Instructions shall
continue in full force and effect unless the Issuing Bank may elect to act upon
additional Instructions delivered to it by the Borrower prior to the issuance of
a Letter of Credit in reliance upon the original Instructions.

                  Section 3.09. Amended Agreement. In the event that the Issuing
Bank shall revise its standard reimbursement agreement executed by each
applicant for a letter of credit, the Borrower shall execute and deliver to the
Issuing Bank an amendment to this Agreement incorporating such changes, promptly
upon request therefor from the Issuing Bank.

                  Section 3.10. Letter of Credit Overdrafts. To the extent that
the Issuing Bank creates an overdraft in any account of the Borrower to satisfy
the Borrower's reimbursement obligation or any other obligation on or related to
any Letter of Credit, such overdraft will, from the Business Day immediately
following the creation of such overdraft, accrue interest at the Default Rate
and both such overdraft and the interest thereon are immediately due and
payable.

                  Section 3.11. Obligation Absolute. The obligations of the
Borrower under this Agreement with regard to each Letter of Credit shall be
absolute, unconditional and irrevocable, and shall be performed strictly in
accordance with the terms of this Agreement and such Letter of Credit, under all
circumstances whatsoever, including, without limitation, the following
circumstances:

                  (a) any lack of validity or enforceability of any of the Loan
Documents or any other agreement or instrument relating thereto;

                  (b) any amendment or waiver of or any consent to departure
from all or any of the Loan Documents or any other agreement or instrument
relating thereto (except to the extent, and only to the extent, expressly agreed
to by the Issuing Bank in such amendment or waiver);

                  (c) the existence of any claim, setoff, defense or other
rights which the Borrower may have at any time against any beneficiary or any
transferee of any Letter of Credit (or any persons or entities for whom any
beneficiary or any such transferee may be acting), the Issuing Bank (other than
the defense of full and timely payment to the Issuing Bank in accordance with
the terms of this Agreement) or any other Person, whether in connection with the
Loan Documents or any other agreement or instrument related thereto or any
related or unrelated transaction;


                                       41
<PAGE>   48


                  (d) any statement or other document or demand presented under
any Letter of Credit (or any endorsement thereon) proving to be forged,
fraudulent, invalid, unenforceable or insufficient in any respect or any
statement therein being untrue or inaccurate in any respect whatsoever;

                  (e) payment by the Issuing Bank under any Letter of Credit
against presentation of a sight draft, certificate or demand by the beneficiary
which does not comply with the terms of such Letter of Credit, including,
without limitation, the circumstances referred to in clause (d) above, or the
failure of any document to bear reference or to bear adequate reference to such
Letter of Credit, except in the case of the Issuing Bank's gross negligence or
willful misconduct in determining whether the documents presented under such
Letter of Credit comply with the terms of such Letter of Credit;

                  (f) any act or omission of the beneficiary in connection with
the use of any Letter of Credit;

                  (g) any failure to preserve or protect any Collateral, any
failure to perfect or preserve the perfection of any Lien thereon, or the
release of any of the Collateral securing the performance or observance of the
terms of the Loan Documents or any other agreement related thereto;

                  (h) any other circumstances or happening whatsoever, whether
or not similar to any of the foregoing.

                  Section 3.12. Change in Law. In addition to the provisions
under Section 3.03(c), if any change in any Law after the Second Closing Date
shall impose, modify or deem applicable any reserve, special deposit, capital
maintenance, deposit insurance premium or assessment, or similar requirement
against letters of credit issued by or assets held by, or sales of
participations in letters of credit or deposits with or for the account of the
Issuing Bank, or impose on the Issuing Bank any other condition regarding this
Agreement or any Letter of Credit or the Participations, or subject the Issuing
Bank to any tax, charge, fee, deduction or withholding of any kind whatsoever
not imposed as of the Second Closing Date (other than taxes imposed on the
overall net income of the Issuing Bank), and the result of any such event shall
be to increase the cost to the Issuing Bank of the issuance or maintenance of
any Letter of Credit or the reimbursement obligations of the Borrower under this
Agreement, or the Participations or reduce the amount of principal, interest, or
any fee or compensation receivable by the Issuing Bank in respect of any Letter
of Credit or this Agreement, or the Participations then, upon demand of the
Issuing Bank, the Borrower shall immediately pay to the Issuing Bank, from time
to time as specified by the Issuing Bank, all additional amounts which are
necessary to compensate the Issuing Bank for such increased cost or


                                       42
<PAGE>   49


reduction incurred by the Issuing Bank. All payments of compensation for such
increased cost or reduction shall be accompanied by interest thereon from the
date of notice of such change until payment in full thereof at the Base Rate.
the Issuing Bank hereby agrees that it will promptly notify the Borrower in
writing of any such increased cost or reduction incurred by the Issuing Bank A
certificate as to such increased cost incurred by the Issuing Bank showing the
manner of calculation thereof shall be submitted by the Issuing Bank to the
Borrower and shall be conclusive (absent manifest error) as to the amount
thereof.

                  Section 3.13. Liability of the Issuing Bank The Borrower
assumes all risks of the acts or omissions of the beneficiary and transferee of
each Letter of Credit with respect to its use of such Letter of Credit. As
between the Borrower and the Issuing Bank, neither the Issuing Bank nor any of
its officers or directors shall be liable or responsible for: (a) the use which
may be made of any Letter of Credit or for any acts or omissions of the
beneficiary and any transferee in connection therewith; (b) the validity,
sufficiency or genuineness of documents, or of any indorsement(s) thereon, even
if such documents should in fact prove to be in any or all respects invalid,
insufficient, fraudulent or forged; (c) payment by the Issuing Bank against
presentation of documents which do not comply with the terms of a Letter of
Credit; or (d) any other circumstance whatsoever in making or failing to make
payment under any Letter of Credit, except only that the Borrower shall have a
claim against the Issuing Bank, and the Issuing Bank shall be liable to the
Borrower, to the extent, but only to the extent, of any direct, as opposed to
consequential, damages suffered by the Borrower which the Borrower proves were
caused by the Issuing Bank's willful misconduct or gross negligence in
determining whether documents presented under a Letter of Credit comply with the
terms of such Letter of Credit. In furtherance and not in limitation of the
foregoing, the Issuing Bank may accept documents that appear on their face to be
in order, without responsibility for further investigation, regardless of any
notice or information to the contrary.

                  Section 3.14. Termination of Obligations. Upon both (1) the
payment in full of all Revolving Credit Loans and the termination of the
Revolving Credit Commitment and (2) December 31, 2002 to the extent any Letters
of Credit are outstanding as of such date, the Borrower shall provide Cash
Collateral for its obligations pursuant to this Article III in an amount
acceptable to the Issuing Bank and at least equal to the undrawn face amount of
all outstanding Letters of Credit, and shall execute all documents and take all
steps required to give the Issuing Bank a perfected first priority security
interest in such collateral (in each case to the reasonable satisfaction of the
Issuing Bank). Upon compliance with the

                                       43
<PAGE>   50

terms of the preceding sentence, the Borrower shall be released from its
obligations pursuant to these Articles VI, VII, VIII and IX. At such time, the
Issuing Bank shall have the right to adjust the rates of interest to be charged
with respect to reimbursements pursuant to Section 3.02 and the commissions and
fees charged pursuant to Section 3.03.

                  Section 3.15. Notice of Request for Extension. During the
period from October 1, 1998 to October 31, 1998, the Borrower will deliver to
the Agent, the Lenders and the Issuing Bank written notice of whether or not it
will request (1) extension of the Letter of Credit Termination Date beyond
January 2, 1998, or (2) the extension of the expiration date of any outstanding
Letter of Credit beyond December 31, 2002.

                  Section 4.01. Participating Lenders' Pro Rata Shares. Subject

Union and NBD agree to purchase a participation from BBH&Co. in the BBH&Co.
Letter of Credit to the extent set forth above opposite First Union's and NBD's
name so that if there is a draw under the BBH&Co. Letter of Credit and the
Borrower fails to reimburse BBH&Co. in the amount of such draw, NBD and First
Union agree to transmit to BBH&Co. their respective Share of such draw or
payment in accordance with the instructions set forth in Section 6.04 of the
1994 Credit Agreement. In addition, prior to the issuance of the Replacement
Letter of Credit and with respect to the BBH&Co. Letter of Credit, the rights
and obligations set forth in this Article IV applicable to a Participating
Lender shall apply to NBC and First Union as participating lenders in the

Article IV applicable to the Issuing Bank shall apply to BBH&Co. as the issuing
bank of the BBH&Co. Letter of Credit.

                  Section 4.02. Sale and Purchase of Participations. Subject to
Section 4.01, each Participating Lender hereby irrevocably and unconditionally
agrees to purchase and the Issuing Bank hereby agrees to sell and transfer to
each Participating Lender, an undivided fractional interest equal to such
Participating Lender's Share in each Letter of Credit and each draw thereunder
upon such drawing and the obligations of the Borrower in respect of each such
Letter of Credit under this Agreement (including all related payments and
recoveries to which such Participating Lender is entitled pursuant to Section
4.05 hereof).

                  Section 4.03. Participation in Fees and Collateral;
Relationship. Each Participating Lender will be entitled to receive a share of
the Letter of Credit Fee, at the time each payment of the Letter of Credit Fee
is paid by the Borrower pursuant to Section 3.03, equal to the total of (1) such
Letter of Credit Fee multiplied by seven eighths of one percent (.875%)
multiplied by (2) its Share (determined at the time such Fee is payable to the
Issuing Bank pursuant to Section 3.03). Agent shall pay the Issuing Bank and
each Participating Lender the portion of the Letter of Credit Fee to which it is
entitled within three (3) Business Days of receipt by Agent of such Fee.

                  In addition to the foregoing, each Participating Lender hereby
purchases, and the Issuing Bank hereby sells to each Participating Lender, an
undivided fractional participation interest equal to such Participating Lender's
Share in the Collateral and any Cash Collateral and all the other Loan
Documents, as well as all additional security specifically assigned to the
Issuing Bank to secure the Letters of Credit.

                  The relationship between the Issuing Bank (in its capacity as
seller of Participations pursuant to this Article IV) and each Participating
Lender (in its capacity as purchaser of Participations pursuant to this Article
IV) is and shall be that of a purchaser and seller of a property interest and
not a creditor-debtor relationship or joint venture. The Issuing Bank (in its
capacity as seller of Participations pursuant to this Article IV) shall owe each
Participating Lender (in its capacity as purchaser of Participations pursuant to
this Article IV) no duty except as specifically set forth in this Article IV.

                  Section 4.04. Procedures. Whenever a draw shall be made under
a Letter of Credit and the Borrower shall fail to reimburse the Issuing Bank
therefor in accordance with this Agreement, the Issuing Bank will promptly
notify each Participating Lender regarding such draw as follows: (1) the date of
such draw, and (2) the amount of such draw. Although the Issuing Bank shall be
responsible for paying each such draw



                                       45
<PAGE>   52

on a Letter of Credit, each Participating Lender shall bear its Share of the
credit risk associated with each such draw. Accordingly, in the event that the
amount of any such draw is not paid in full by or on behalf of the Borrower when
required in accordance with the terms of this Agreement, for any reason, the
Issuing Bank shall give prompt notice by telephone (promptly confirmed in
writing) or telex to each Participating Lender of such event. Upon receipt of
such telephone or telex notice, each Participating Lender shall cause to be
transmitted to the Issuing Bank, via CHIPS or, if transmission via CHIPS is not
possible, via federal funds transfer, in accordance with the instructions set
forth below an amount in immediately available funds equivalent to its Share of
such draw or payment in such manner to ensure that such funds are received by
the Issuing Bank, and available to the Issuing Bank by 3:00 p.m., New York City
time, on the date demand therefor was made by the Issuing Bank (if demand was
made by 12:00 noon, New York City time) or by 10:00 a.m., New York City time, on
the Business Day following the date demand therefor was made (if demand was made
after 12:00 noon, New York City time).

                  Section 4.05. Collections and Remittances. Whenever the
Issuing Bank receives any payment, interest, reimbursement, collection, or
recovery on account of a Letter of Credit whether from the Borrower, the
Collateral, the Cash Collateral, or otherwise, it shall allocate such receipts
as follows:

                           (a) To the payment of taxes, assessments, insurance
                  premiums, or for similar purposes as required by the
                  applicable Letter of Credit or any other Loan Document, and,
                  if previously paid by the Issuing Bank, such sums shall be
                  retained by the Issuing Bank; and

                           (b) In the event the Borrower fails to reimburse the
                  Issuing Bank for any draw under a Letter of Credit when due
                  and the Issuing Bank receives a payment of or on account of
                  such defaulted amount as to which a Participating Lender has
                  paid the Issuing Bank the amount of its Share pursuant to
                  Section 4.04, that portion of the amount received shall be
                  allocated between each such Participating Lender and the
                  Issuing Bank pro rata, with each such

                                       46
<PAGE>   53


                  Participating Lender's percentage of the principal amount
                  based on its Share.

                  After the Issuing Bank receives a payment on account of a
Letter of Credit and makes the allocations required by the preceding paragraph,
it shall give notice to each Participating Lender not later than 11:30 a.m. New
York City time, by telephone and promptly remit to each Participating Lender (or
credit to the Participating Lender's account with the Issuing Bank, if any), the
amount to which each such Participating Lender is entitled; provided, however,
that the Issuing Bank may retain and deduct from such payment to any such
Participating Lender any amounts owed the Issuing Bank by such Participating
Lender pursuant to this Article IV.

                  If any payment received by the Issuing Bank and distributed or
credited to a Participating Lender is later rescinded or is otherwise returned
by the Issuing Bank for whatever reason (including, without limitation,
settlement of an alleged claim), each such Participating Lender, upon demand by
the Issuing Bank, shall immediately pay to the Issuing Bank such Participating
Lender's Share of the principal amount so returned plus interest and/or
commission on such amount at the rate specified above in Section 3.03. The
covenants contained in this paragraph shall survive the termination of this
Agreement.

                  Section 4.06. Sharing of Setoffs and Collections. Each
Participating Lender agrees that to the extent any payment is received by it on
any of the Borrower's obligations under a Letter of Credit, whether by
counterclaim, setoff, banker's lien, by realizing on collateral or otherwise and
such payment results in such Participating Lender receiving a greater payment
than it would have been entitled to under Section 4.05 had the total amount of
such payment been paid directly to the Issuing Bank for disbursement according
to that Section, then such Participating Lender shall immediately purchase for
cash from the Issuing Bank an additional Participation and a participation from
the other Participating Lenders in such Letter of Credit (subject to the same
terms and conditions provided for herein), sufficient in amount so that such
payment shall effectively be shared pro rata with the Issuing Bank and the other
Participating Lenders in accordance with the amount, and to the extent, of their
respective interests in the Letter of Credit; provided, however, that if all or
any portion of such payment is thereafter recovered from such Participating
Lender at any time, the purchase shall be rescinded and the purchase price
returned to the extent of such recovery, but without interest or other return
thereon.

                  Section 4.07. Indemnification; Costs and Expenses. To the
extent not reimbursed by the Borrower, and without limiting the obligation of
the Borrower to do so, each


                                       47
<PAGE>   54


Participating Lender agrees to reimburse the Issuing Bank for, indemnify the
Issuing Bank against, and hold the Issuing Bank harmless from, on demand (and
the Issuing Bank is authorized to debit each such Participating Lender's
account, if any, with the Issuing Bank for the same), to the extent of each such
Participating Lender's Share of any and all liabilities, obligations, losses,
damages, penalties, actions, judgments, suits, costs, expenses, or disbursements
of any kind whatsoever (including, without limitation, disbursements necessary,
in the judgment of the Issuing Bank, to preserve or protect the Collateral or
Cash Collateral), that may at any time be imposed on, incurred by, or asserted
against the Issuing Bank in any way relating to this Agreement, a Letter of
Credit, the Collateral, the Cash Collateral or any other Loan Document or other
instrument relating to any of the foregoing, or the transactions contemplated
thereby and hereby, or any action taken or omitted by the Issuing Bank under or
in connection with any of the foregoing; provided, however, that no
Participating Lender shall be liable for the payment of any portion of such
liabilities, obligations, losses, damages, penalties, actions, judgments, suits,
costs, expenses, or disbursements resulting from the Issuing Bank's gross
negligence or willful misconduct. The covenants contained in this Section 4.07
shall survive the termination of this Agreement.

                  Section 4.08. Administration; Standard of Care. The Issuing
Bank will administer the Letter of Credit in the ordinary course of business and
in accordance with its usual practices, modified from time to time as it deems
appropriate under the circumstances. Except as expressly set forth in the third
paragraph of this Section 4.08, the Issuing Bank shall be entitled to use its
discretion in taking or refraining from taking any actions in connection with
any of the foregoing as if it were the sole party involved in any of the
foregoing and no Participations existed.

                  Each Participating Lender acknowledges that its Participations
hereunder are without recourse to the Issuing Bank and that each such
Participating Lender expressly assumes all risk of loss in connection with its
Participation in the Letters of Credit as if such Participating Lender had
directly provided such Letters of Credit. The Issuing Bank shall have no
liability, express or implied, for any action taken or omitted to be taken by
the Issuing Bank or for any failure or delay in exercising any right or power
possessed by the Issuing Bank under any of the Loan Documents except for actual
losses, if any, suffered by any Participating Lender that are proximately caused
either by the Issuing Bank's gross negligence or by the Issuing Bank's willful
misconduct. Without limiting the foregoing, the Issuing Bank (1) may consult
with legal counsel, independent public accountants, appraisers, and other
experts, selected by the Issuing Bank,


                                       48

and shall not be liable for any action taken or omitted to be taken in good
faith by it in accordance with the advice of such persons, (2) shall be entitled
to rely on, and shall incur no liability by acting upon, any conversation,
notice, consent, certificate, statement, order, or any document or other writing
(including, without limitation, telegraph, telex, telecopy, TWX, or other
telecommunication device) believed by the Issuing Bank to be genuine and correct
and to have been signed, sent, or made by the proper person, (3) makes no
warranty or representation of any kind of character relating to the Borrower,
the Collateral or the Cash Collateral, and shall not be responsible for any
warranty or representation made in or in connection with any of the Loan
Documents, (4) makes no warranty or representation as to, and shall not be
responsible for the correctness as to form, the due execution, legality,
validity, enforceability, genuineness, sufficiency, or collectability of any of
the Loan Documents, for any failure by the Borrower or any Person to perform its
obligations thereunder, for the Borrower's use of the proceeds therefrom, or for
the preservation of the Collateral, the Cash Collateral, or the loss,
depreciation, or release thereof, (5) makes no warranty or representation as to,
and assumes no responsibility for, the authenticity, validity, accuracy, or
completeness of any notice, financial statement, or other document or
information received by the Issuing Bank or any Participating Lender in
connection with, or otherwise referred to in, any of the Loan Documents, and (6)
shall not be required to make any inquiry concerning the observance or
performance of any agreement contained in, or conditions of, any of the Loan
Documents, or to inspect the property, books, or records of the Borrower or any
Person.

                  Notwithstanding the provisions of the first paragraph of this
Section 4.08, the Issuing Bank agrees that it will not knowingly take any of the
following actions without the written consent of each Participating Lender: (1)
waive any default by the Borrower involving the payment of money to the Issuing
Bank pursuant to any of the Loan Documents; (2) extend the time of payment of
interest on the Borrower's obligations to the Issuing Bank with respect to any
Letter of Credit; (3) extend the maturity date of a Letter of Credit beyond
December 31, 2002 without the consent of all the Participating Lenders; (4)
increase the amount of any Letter of Credit; (5) reduce the Letter of Credit
Fee; or (6) release any Collateral, except as otherwise contemplated in any Loan
Documents. the Issuing Bank shall be fully justified in failing or refusing to
take any action under any of the Loan Documents unless it shall first receive
such advice or concurrence of the Participating Lenders as the Issuing Bank
shall deem appropriate.

                  the Issuing Bank may lend money to, accept deposits from, and
generally engage in any kind of business with the

                                       49

Borrower as freely as though no Participations had been granted to a
Participating Lender.

                  Section 4.09. Independent Investigation by the Participating
Lenders. Each Participating Lender acknowledges (1) that the Issuing Bank has
provided such Participating Lender with copies of all of the Loan Documents and
the Borrower has provided or granted such Participating Lender access to certain
financial data and other information pertaining to the Borrower that such
Participating Lender has requested in order to enable it to make an independent,
informed judgment with respect to the desirability of purchasing Participations
in the Letters of Credit, (2) that the Issuing Bank has not made any
representations or warranties to such Participating Lender and that no prior or
future act by the Issuing Bank, including, without limitation, any review of the
affairs of the Borrower, shall be deemed to constitute a representation or
warranty of the Issuing Bank, and (3) that such Participating Lender has
independently, without reliance upon the Issuing Bank, and based on such
information as such Participating Lender has deemed appropriate, made its own
appraisal of and investigation into the business, operations, property,
financial condition, and general creditworthiness of the Borrower, made its own
analysis of the value and Lien status of any Collateral or Cash Collateral, and
made its own decision to execute this Agreement and thereby purchase
Participations in accordance with this Article IV in the Letters of Credit. Each
Participating Lender agrees that, independently and without reliance upon the
Issuing Bank or any representations or statements of the Issuing Bank, and based
on such information as such Participating Lender deems appropriate at the time,
it will continue to make and rely upon its own credit analysis and decisions in
taking or not taking any action under this Article IV or any of the Loan
Documents.

                  Section 4.10. Participating Lenders' Ownership of Interests in
the Participations. Each Participating Lender hereby represents and warrants to
the Issuing Bank that the purchase of its Participation in the Letters of Credit
(1) is a legal investment pursuant to the laws under which such Participating
Lender is organized and operates, (2) has been duly authorized and approved by
all necessary action of the management of such Participating Lender, and (3) is
made for such Participating Lender's own account for the purpose of investment
only and with no present intention of disposing of the same.

                   ARTICLE VI. REPRESENTATIONS AND WARRANTIES

                  The Borrower hereby represents and warrants that:

                  Section 6.01. Incorporation, Good Standing and Due
Qualification. The Borrower and each of its Subsidiaries are duly incorporated,
validly existing and in good standing under the laws of the respective
jurisdictions of their incorporation, have the corporate power and authority to
own their assets and to transact the business in which they are now engaged or
proposed to be engaged, and are duly qualified as foreign corporations and in
good standing under the laws of each other jurisdiction in which such
qualification is required, except to the extent that its failure to be so
qualified could not reasonably be expected to result in a Material Adverse
Change.

                  Section 6.02. Corporate Power and Authority; No Conflicts.
The execution, delivery and performance by the Borrower of the Loan Documents
have been duly authorized by all necessary corporate action and do not and will
not: (1) require any consent or approval of its stockholders; (2) contravene its
certificate of incorporation or by-laws; (3) violate any provision of, or
require any filing, registration, consent or approval under, any Law (including,
without limitation, Regulations G, T, U and X of the Board of Governors), order,
writ, judgment, injunction, decree, determination or award presently in effect
having applicability to the Borrower or any of its Subsidiaries; (4) result in a
breach of or constitute a default under or require any consent under any
indenture or loan or credit agreement or any other agreement, lease or
instrument to which the Borrower or any of its Subsidiaries is a party or by
which it or its properties may be bound or affected; (5) result in, or require,
the creation or imposition


                                       53
<PAGE>   60


of any Lien (other than as created under the Borrower Pledge Agreement or the
Borrower Pledge Agreement (Navigators)), upon or with respect to any material
properties now owned or hereafter acquired by the Borrower or any of its
Subsidiaries; or (6) cause the Borrower or any of its Subsidiaries to be in
default under any such Law, order, writ, judgment, injunction, decree,
determination or award or any such indenture, agreement, lease or instrument.

                  Section 6.03. Legally Enforceable Agreements. Each Loan
Document to which the Borrower is a party is a legal, valid and binding
obligation of the Borrower, enforceable against the Borrower in accordance with
its terms.

                  Section 6.04. Litigation. There are no actions, suits or
proceedings (private or governmental) pending or, to the knowledge of the
Borrower, threatened, against or affecting the Borrower or any of its
Subsidiaries before any Governmental Authority or arbitrator, which could, in
any one case or in the aggregate, reasonably be expected to result in a Material
Adverse Change.

                  Section 6.05. Financial Statements. The consolidated balance
sheets of the Borrower and the Consolidated Subsidiaries as of December 31,
1995, the related consolidated statements of income, consolidated statements of
stockholders' equity, and consolidated statements of cash flows of the Borrower
and such Consolidated Subsidiaries for the Fiscal Year then ended, and the
accompanying footnotes, together, with the opinion thereon, dated March 12, 1996
(except for Note 16 which is as of March 19, 1996) of KPMG Peat Marwick,
independent certified public accountants, copies of which have been furnished to
the Lenders, fairly present the financial condition of the Borrower and the
Consolidated Subsidiaries as at such dates and the results of the operations of
the Borrower and Consolidated Subsidiaries for the periods covered by such
statements, all in accordance with GAAP consistently applied, and since December
31, 1995 there has been no Material Adverse Change.

                  The combined balance sheets of the Somerset Companies as of
December 31, 1995 and the related combined statements of income, copies of which
have been furnished to the Lenders, fairly present the financial condition of
the Somerset Companies as of such dates and the results of the operations of the
Somerset Companies for the periods covered by such statements, all in accordance
with GAAP consistently applied.

                  The consolidated balance sheets of the Borrower and the
Consolidated Subsidiaries as of September 30, 1996 and the related consolidated
statements of income, consolidated statements of stockholders' equity, and
consolidated statements of cash flows of the Borrower and such Consolidated


                                       54
<PAGE>   61


Subsidiaries for the Fiscal Quarter then ended, copies of which have been
furnished to the Lenders, fairly present the financial condition of the Borrower
and the Consolidated Subsidiaries as at such dates and the results of the
operations of the Borrower and Consolidated Subsidiaries for the periods covered
by such statements, all in accordance with GAAP consistently applied (subject to
changes resulting from normal year-end audit adjustments) and since September
30, 1996 there has been no Material Adverse Change.

                  The combined balance sheets of the Somerset Companies as of
September 30, 1996 and the related combined statements of income, copies of
which have been furnished to the Lenders, fairly present the financial condition
of the Somerset Companies as of such dates and the results of the operations of
the Somerset Companies for the periods covered by such statements, all in
accordance with GAAP consistently applied (subject to changes resulting from
normal year-end audit adjustments).

                  There are no liabilities of the Borrower or any of the
Consolidated Subsidiaries, fixed or contingent, which are material but are not
reflected in the most recent financial statements referred to above or in the
notes thereto, other than liabilities arising in the ordinary course of business
since September 30, 1996. No information, exhibit, or report furnished by the
Borrower or any Consolidated Subsidiaries to the Agent or any Lender in
connection with the negotiation of this Agreement and the other Loan Documents
contained any material misstatement of fact or omitted to state a material fact
or any fact necessary to make the statements contained therein, in light of the
circumstances under which they were made, and at the time they were made, not
materially misleading.

                  Section 6.06. Statutory Financial Statements. The Annual
Statement of each of the Insurance Subsidiaries (including, without limitation,
the provisions made therein for investments and the valuation thereof, reserves,
policy and contract claims and Statutory Liabilities) as filed with the
appropriate Governmental Authority of its state of domicile (the "Department")
and delivered to each Lender prior to the execution and delivery of this
Agreement, as of and for the 1993, 1994 and 1995 Fiscal Years, and as of and for
the Fiscal Quarter ended September 30, 1996 (collectively, the "Statutory
Financial Statements"), have been prepared in accordance with SAP applied on a
consistent basis (except as noted therein). Each such Statutory Financial
Statement was in compliance with applicable Law when filed. The Statutory
Financial Statements fairly present the financial position, the results of
operations, changes in equity and changes in financial position of each such
Insurance Subsidiary as of and for the respective dates and period indicated
therein in accordance with SAP


                                       55
<PAGE>   62


applied on a consistent basis, except as set forth in the notes thereto. Except
for liabilities and obligations, including, without limitation, reserves, policy
and contract claims and Statutory Liabilities (all of which have been computed
in accordance with SAP), disclosed or provided for in the Statutory Financial
Statements, the Insurance Subsidiaries did not have, as of the respective dates
of each of such financial statements, any liabilities or obligations (whether
absolute or contingent and whether due or to become due) which, in conformity
with SAP, applied on a consistent basis, would have been required to be or
should be disclosed or provided for in such financial statements. All books of
account of each of the Insurance Subsidiaries fully and fairly disclose all of
the material transactions, properties, assets, investments, liabilities and
obligations of such Insurance Subsidiary and all of such books of account are in
the possession of each such Insurance Subsidiary and are true, correct and
complete in all material respects.

                  The investments of Insurance Subsidiaries reflected in the
Annual Statements filed with the respective Departments with respect to the 1995
Fiscal Year (the "1995 Annual Statement") and the September 30, 1996 Quarterly
Statement (the "1996 Quarterly Statement") complied in all material respects, as
of the dates of such statements, with all applicable requirements of the
Department with respect to each such Insurance Subsidiary as well as those of
any other applicable jurisdiction relating to investments in respect of which it
may invest its funds.

                  The provisions made by each Insurance Subsidiary in its 1995
Annual Statement and in its 1996 Quarterly Statement for reserves, policy and
contract claims and Statutory Liabilities were in compliance in all material
respects, as of the dates of such statements, with the requirements of the
applicable Department as well as those of any other applicable jurisdiction, and
have been computed in accordance with SAP.

                  Marketable securities and short term investments reflected in
the 1995 Annual Statement and in the 1996 Quarterly Statement of each Insurance
Subsidiary are valued at cost, amortized cost or market value, as required by
applicable law as of the date of such statements.

                  Since December 31, 1995, there has been no adverse change in
the business, assets, operations or financial condition of the Borrower or any
Subsidiary which has or could reasonably be expected to result in a Material
Adverse Change. No dividends or other distributions have been declared, paid or
made upon any shares of capital stock of the Borrower, nor have any shares of
capital stock of the Borrower been redeemed, retired, purchased or otherwise
acquired by the Borrower since


                                       56
<PAGE>   63


December 31, 1995, except to the extent permitted under the terms of this
Agreement.

                  Section 6.07. Ownership and Liens. The Borrower and each of
its Subsidiaries has title to, or valid leasehold interests in, all of their
properties and assets, real and personal, including the properties and assets,
and leasehold interests reflected in the financial statements referred to in
Section 6.05 (other than any properties or assets disposed of in the ordinary
course of business), and none of the properties and assets owned by the Borrower
and none of its leasehold interests are subject to any Lien, except as may be
permitted under this Agreement.

                  Section 6.08. Taxes. The Borrower and each of its
Subsidiaries has filed all tax returns and reports (federal, state, local and
foreign) required to be filed and have paid all taxes, assessments and
governmental charges and levies reported thereon to be due, including interest
and penalties, except to the extent they are the subject of a Good Faith
Contest.

                  Section 6.09. ERISA. Each Plan is administered in compliance
in all material respects with its terms and all applicable provisions of ERISA
and the Code. No Plan is subject to Title IV of ERISA; neither the Borrower nor
any other Person, including any fiduciary, has engaged in any Prohibited
Transaction which could reasonably be expected to subject the Borrower or any of
its Subsidiaries, or any entity which they have an obligation to indemnify, to
any material tax or penalty imposed under Section 4975 of the Code or Section
502(i) of ERISA; no Plan has been terminated and, to the best knowledge of the
Borrower, no notice of intent to terminate a Plan has been filed which, as a
result thereof could reasonably be expected to result in liability to the
Borrower or any of its Subsidiaries; no Plan is a Multiemployer Plan and neither
the Borrower nor any ERISA Affiliate has completely or partially withdrawn under
Section 4201 or 4204 of ERISA from a Multiemployer Plan which, as a result
thereof could reasonably be expected to result in liability to the Borrower or
any of its Subsidiaries, or incurred liability with respect to Section 515 of
ERISA; the Borrower has met the applicable minimum funding requirements under
ERISA with respect to all of its Plans and there has been no material failure on
the part of the Borrower's ERISA Affiliates to meet such requirements; a
favorable determination letter from the IRS has been received with respect to
each Plan intended to be qualified under Section 401(a) or 401(k) of the Code
and nothing has occurred which could reasonably be expected to adversely affect

for the value, legality, validity, effectiveness, genuineness, enforceability or
sufficiency of this Agreement or any other Loan Document or any other document
or instrument referred to or provided for herein or therein, for the perfection

thereunder or for any failure by the Borrower to perform any of its obligations
hereunder or thereunder. The Agent may employ agents and attorneys-in-fact and

responsible for any action taken or omitted to be taken by it or them hereunder
or under any other Loan Document or in connection herewith or therewith, except

Agreement or any other Loan Document, the Agent shall in all cases be fully
protected in acting, or in refraining from acting, hereunder in accordance with

Event of Default, the Agent shall give prompt notice thereof to the Lenders. The
Agent shall

Event of Default which is continuing as shall be directed by the Required
Lenders; provided, that, unless and until the Agent shall have received such
directions, the Agent may take such action, or refrain from taking such action,

required to take any such action which it determines to be contrary to Law.

Lender hereunder shall have the same rights and powers hereunder as any other
Lender and may exercise the same as though it were not acting as the Agent, and
the term "Lender" or "Lenders" shall, unless the context otherwise indicates,
include the Agent in its capacity as a Lender. The Agent and its affiliates may
(without having to account therefor to any Lender) accept deposits from, lend
money to (on a secured or unsecured basis), and generally engage in any kind of
banking, trust or other business with the Borrower and any of its Affiliates as
if it were not acting as the Agent, and the Agent may accept fees and other
consideration from the Borrower for services in connection with this Agreement
or otherwise without having to account for the same to the Lenders.

and its officers, directors, partners, employees and agents, for such Lender's
Pro Rata Share of any and all liabilities, obligations, losses, damages,
penalties, actions, judgments, suits, costs, expenses or disbursements of any
kind and nature whatsoever which may be imposed on, incurred by or asserted
against the Agent in any way relating to or arising out of this Agreement, any
other Loan Document or any other documents contemplated by or referred to herein
or the transactions contemplated hereby or thereby (including, without
limitation, the costs and expenses which the Borrower are obligated to pay under
Section 12.03) or under the applicable provisions of any other Loan Document or
the enforcement of any of the terms hereof or thereof or of any such other
documents or instruments; provided, that no Lender shall be liable for any of
the foregoing to the extent they arise from (1) the gross negligence or willful
misconduct of the Agent or (2) a dispute between or among the Agent and one or
more Lenders.

                  Section 11.06. Non-Reliance on the Agent and the other

own credit analysis of the Borrower and the decision to enter into this
Agreement and that it will, independently and without reliance upon the Agent or

appropriate at the time, continue to make its own analysis and decisions in
taking or not taking action under this Agreement or any other Loan Document. The
Agent shall not be required to keep itself informed as to the performance or
observance by the Borrower of this Agreement or any other Loan Document or any
other document referred to or provided for herein or therein or to inspect the
properties or books of the Borrower. Except for notices, reports and other
documents and information expressly required to be furnished to the Lenders by

may come into the possession of the Agent or any of its Affiliates. The Agent
shall not be required to file this Agreement, any other Loan Document or any
document or instrument referred to herein or therein, for record or give notice
of this Agreement, any other Loan Document or any document or instrument
referred to herein or therein, to anyone.

expressly required of the Agent hereunder, the Agent shall in all cases be fully
justified in failing or refusing to act hereunder unless it shall have received
further assurances (which may include cash collateral) of the indemnification
obligations of the Lenders under Section 11.05 in respect of any and all
liability and expense which may be incurred by it by reason of taking or
continuing to take any such action.

shall have been so appointed by the Required Lenders and shall have accepted
such appointment within thirty (30) days after the retiring Agent's giving of

departure by the Borrower therefrom, shall in any event be effective unless the
same shall be in writing and signed by the Required Lenders and then such waiver
or consent shall be effective only in the specific instance and for the specific
purpose for which given. No failure on the part of the Agent or any Lender to
exercise, and no delay in exercising, any right hereunder shall operate as a
waiver thereof or preclude any other or further exercise thereof or the exercise
of any other right. The remedies herein provided are cumulative and not
exclusive of any remedies provided by Law.

                  Section 12.02. Usury. Anything herein to the contrary
notwithstanding, the obligations of the Borrower under this Agreement and the
Notes shall be subject to the limitation that payments of interest shall not be
required to the extent that receipt thereof would be contrary to provisions of
Law


                                       85

applicable to a Lender limiting rates of interest which may be charged or
collected by such Lender.

                  Section 12.03. Expenses; Indemnification. The Borrower agrees
to reimburse the Agent, on demand for all costs, expenses, and charges
(including, without limitation, out-of-pocket costs and all reasonable fees and
charges of external legal counsel for the Agent, but not the legal fees for
internal or external legal counsel of the Lenders) incurred by the Agent, in
connection with the preparation of the Loan Documents. The Borrower agrees to
reimburse the Agent and each of the Lenders on demand for all costs, expenses,
and charges (including, without limitation, out-of-pocket costs and all
reasonable fees and charges of internal and external legal counsel for the Agent
and each Lender) incurred by the Agent or Lender in connection with the
performance, or enforcement of this Agreement, the Notes, or any other Loan
Documents. The Borrower agrees to indemnify the Agent and each Lender and their
respective directors, officers, partners, employees and agents from, and hold
each of them harmless against, any and all losses, liabilities, claims, damages
or expenses incurred by any of them arising out of or by reason of any
investigation or litigation or other proceedings (including any threatened
investigation or litigation or other proceedings) relating to any actual or
proposed use by the Borrower of the proceeds of the Loans or to any violation or
alleged violation of any Environmental Law by the Borrower, including, without
limitation, the reasonable fees and disbursements of internal and external
counsel incurred in connection with any such investigation or litigation or
other proceedings (but excluding any such losses, liabilities, claims, damages
or expenses incurred by reason of the gross negligence or willful misconduct of
the Person to be indemnified). If any taxes (excluding taxes imposed upon or
measured by the net income of any Lender) shall be payable on account of the
execution or delivery of this Agreement or the creation of any of the
obligations hereunder by reason of any existing federal or state statute, the
Borrower will pay all such taxes, including any interest and penalties thereon,
and will indemnify and hold the Lenders harmless from and against liability in
connection therewith.

                  The Borrower authorizes the Agent to debit any of its accounts
maintained with the Agent, any Lender or the Issuing Bank for any fees and
expenses owing to the Agent, any Lender or the Issuing Bank under the terms and
provisions of this Agreement; provided, however, the Agent shall promptly notify
the Borrower in the case of each such debit; provided, further, the Agent's
failure to give such notice shall not affect the validity thereof.

                  The obligations of the Borrower under this Section 12.03 shall
survive the repayment of the Loans and all amounts


                                       86
<PAGE>   93

due under or in connection with any of the Loan Documents and the termination of
the Commitments.

                  Section 12.04. Assignment; Participation. This Agreement shall
be binding upon, and shall inure to the benefit of, the Borrower, the Agent, the
Lenders and their respective successors. Neither the Borrower nor the Lenders
may assign or transfer their respective rights or obligations hereunder. Except
as provided in Section 12.06, none of the Lenders may sell participations in its
rights, duties and obligations under this Agreement or any of the other Loan
Documents.

                  Section 12.05. Notices. Unless the party to be notified
otherwise notifies the other party in writing as provided in this Section 12.05,
and except as otherwise provided in this Agreement, notices shall be given to
the Agent by telephone, confirmed in writing and delivered by hand or confirmed
telecopier, and to the Lenders and to the Borrower by written notice delivered
by hand, overnight courier service or confirmed telecopier addressed to such
party at its address on the signature page of this Agreement. Notices shall be
effective upon receipt.

                  Section 12.06. Setoff. The Borrower agrees that, in addition
to (and without limitation of) any right of setoff, bankers' lien or
counterclaim a Lender may otherwise have, each Lender shall be entitled, at its
option, to offset balances (general or special, time or demand, provisional or
final) held by it for the account of the Borrower at any of such Lender's
offices, in Dollars or in any other currency, against any amount payable by the
Borrower to such Lender under this Agreement or any of such Lender's Notes, or
any other Loan Document which is not paid when due (regardless of whether such
balances are then due to the Borrower), in which case it shall promptly notify
the Borrower and the Agent thereof; provided, that such Lender's failure to give
such notice shall not affect the validity thereof. Each Lender agrees that to
the extent any such payment is received by it as the result of a set-off or
otherwise and such payment results in such Lender receiving a greater payment
than it would have been entitled to, had the total amount of such payment been
paid directly to the Agent for disbursement to the Lenders, then such Lender
shall immediately purchase for cash from the other Lenders participations in the
loans sufficient in amount so that such payment shall effectively be shared pro
rata with the other Lenders in accordance with the amount, and to the extent, of
their respective interests in all the Loans; provided, however, that, if all or
any portion of such payment is thereafter recovered from such Lender at any
time, the purchase shall be rescinded and the purchase price returned to the
extent of such recovery, but without interest or other return thereon.

                  Section 12.07. Jurisdiction; Immunities. The Borrower hereby
irrevocably submits to the jurisdiction of any New York State or United States
Federal court sitting in New York City over any action or proceeding arising out
of or relating to this Agreement, the Notes or any other Loan Document, and the
Borrower hereby irrevocably agrees that all claims in respect of such action or
proceeding may be heard and determined in such New York State or Federal court.
The Borrower irrevocably consents to the service of any and all process in any
such action or proceeding by the mailing of copies of such process to the
Borrower at its address specified in Section 12.05. The Borrower agrees that a
final judgment in any such action or proceeding shall be conclusive and may be
enforced in other jurisdictions by suit on the judgment or in any other manner
provided by law. The Borrower further waives any objection to venue in such
State and any objection to an action or proceeding in such State on the basis of
forum non convenience. The Borrower agrees that any action or proceeding brought
against the Agent or any Lender shall be brought only in New York State or
United States Federal court sitting in New York County.

                  Nothing in this Section 12.07 shall affect the right of the
Agent or any Lender to serve legal process in any other manner permitted by law
or affect the right of the Agent or any Lender to bring any action or proceeding
against the Borrower or its property in the courts of any other jurisdictions.

                  To the extent that the Borrower has or hereafter may acquire
any immunity from jurisdiction of any court or from any legal process (whether
from service or notice, attachment prior to judgment, attachment in aid of
execution, execution or otherwise) with respect to itself or its property, the
Borrower hereby irrevocably waives such immunity in respect of its obligations
under this Agreement, the Notes, and any other Loan Document.

                  Section 12.08. Governing Law. This Agreement shall be governed
by and construed in accordance with the laws of the State of New York applicable
to agreements made and to be performed entirely within such State.

                  Section 12.09. Counterparts. This agreement may be executed by
the parties hereto in separate counterparts, each of which, when so executed and
delivered, shall be an original, but all such counterparts shall together
constitute one and the same instrument. Each counterpart may consist of a number
of copies hereof, each signed by less than all, but together signed by all of
the parties hereto.

                  Section 12.10. Exhibits and Schedules. The Exhibits and
Schedules hereto are a part of this Agreement as if fully set forth herein. All

subsections, clauses, Exhibits and Schedules shall be deemed references to such
parts of this Agreement, unless the context shall otherwise require.

                  Section 12.11. Table of Contents; Headings. The headings in
the Table of Contents and in this Agreement are for reference only, and shall
not affect the interpretation or construction of this Agreement.

                  Section 12.12. Severability. If any word, phrase, sentence,
paragraph, provision or section of this Agreement shall be held, declared,
pronounced or rendered invalid, void, unenforceable or inoperative for any
reason by any court of competent jurisdiction, governmental authority, statute
or otherwise, such holding, declaration, pronouncement or rendering shall not
adversely affect any other word, phrase, sentence, paragraph, provision or
section of this Agreement, which shall otherwise remain in full force and effect
and be enforced in accordance with its terms.

                  Section 12.13. Integration. The Loan Documents set forth the
entire agreement among the parties hereto relating to the transactions
contemplated thereby and supersede any prior oral or written statements or
agreements with respect to such transactions.

                  Section 12.14. Prior Regulatory Approvals. The parties hereto
understand and agree that neither the Agent nor the Lender may exercise control
over NIC without prior approval of the New York Insurance Department in
accordance with the New York Insurance Law.
