ITEM 1. BUSINESS

General Description of the Company's Business

         W. R. Berkley Corporation (the "Company"), a Delaware corporation, is
an insurance holding company which, through its subsidiaries, presently operates
in all segments of the property casualty insurance business: regional property
casualty insurance; reinsurance; specialty lines of insurance (including excess
and surplus lines and commercial transportation); alternative markets (including
the management of alternative insurance market mechanisms); and international.
The Company was founded on the concept that a group of autonomous regional and
specialty insurance entities could compete effectively in selected markets
within a very large industry. Decentralized control allows each subsidiary or
regional group to respond to local or specialty market conditions while
capitalizing on the effectiveness of centralized investment and reinsurance
management and actuarial, financial and legal staff support.

         The Company's regional insurance operations are conducted primarily in
the New England, Mid Atlantic, Midwest and Southern regions of the United
States. Reinsurance, specialty insurance and alternative markets operations are
conducted nationwide. Presently, international operations are conducted
primarily in Argentina and the Philippines.

         Net premiums written, as reported on a generally accepted accounting
principles ("GAAP") basis, by the Company's five major insurance industry
segments for the five years ended December 31, 1999 were as follows:

         The following sections briefly describe the Company's insurance
segments and subsidiaries. The statutory information contained herein is derived
from that reported to state regulatory authorities in accordance with statutory
accounting practices ("SAP"). The descriptions contain each significant
insurance subsidiary's rating by A.M. Best and Company, Inc. ("A.M. Best"). A.M.
Best's ratings are based upon factors of concern to policyholders, insurance
agents and brokers and are not directed toward the protection of investors. A.M.
Best states: "Best's Ratings reflect [its] opinion as to the relative financial
strength and performance of each insurer in comparison with others, based on
[its] analysis of the information provided to [it]. These ratings are not a
warranty of an insurer's current or future ability to meet its contractual
obligations." A.M. Best reviews its ratings on a periodic basis, and ratings of
the Company's subsidiaries are therefore subject to change.

                          REGIONAL INSURANCE OPERATIONS

The Company's regional property casualty subsidiaries write standard commercial
and personal lines insurance for such risks as automobiles, homes and
businesses. The Company's regional insurance operations have historically been
conducted through ten principal operating subsidiaries. In 1999, the Company
restructured the management and back-office operations of these ten companies
into four geographic units based on markets served. As part of the
restructuring, certain back office functions and operating redundancies were
minimized or eliminated.

         The regional groups, and the primary regional company for each group,
are as follows:

         - New England - Acadia Insurance Company

         - Mid Atlantic - Firemen's Insurance Company of Washington, D.C.

         - Midwest - Continental Western Insurance Company

         - Southern Tier - Union Standard Insurance Company

         Berkley Regional Insurance Company ("BRIC"), an intermediate holding
company, owns all of the capital stock of the regional insurance companies and
reinsures varying portions of the business written by the regional operations.
BRIC is currently rated A by A.M. Best. This is a group rating which applies
to each of the regional insurance companies and certain other subsidiaries as
noted herein.

                             REINSURANCE OPERATIONS

         The Company's reinsurance operations consist of six operating units,
which specialize in underwriting property, casualty and surety reinsurance on
both a treaty and a facultative basis. The Company's reinsurance operations are
conducted by Signet Star Holdings, Inc. through its subsidiary Signet Star
Reinsurance Company ("Signet Star"). For financial segment reporting purposes,
the results of the alternative market division of Signet Star are included in
the Company's alternative markets segment. Signet Star is rated A by A.M. Best.

         The Property Casualty Treaty Division is the largest business unit in
terms of personnel and premiums written. This division of Signet Star is
committed exclusively to the broker market segment of the treaty reinsurance
industry. It functions as a traditional reinsurer in specialty and standard
reinsurance lines. This unit is de-emphasizing commodity lines of business,
which are experiencing intense competition brought on, in part, by excess
capacity.


         Facultative ReSources, Inc. ("Fac Re"), an underwriting manager,
specializes in individual certificate and program facultative business. Fac Re's
highly experienced underwriters seek to offset the underwriting and pricing
cycles in the underlying insurance business by developing risk management
solutions and through superior risk selection. Fac Re develops its business
through brokers and on a direct basis where the client does not choose to use an
intermediary.


         The Fidelity and Surety Division ("F&S") operates as a lead reinsurer
in a niche market of the property casualty industry where its highly specialized
knowledge and expertise are essential to meet the needs of fidelity and surety
primary writers. Business is marketed principally through brokers as well as
directly to clients not served by intermediaries.


         Gemini Insurance Company is an excess and surplus line insurance
company which commenced business in 1997 to provide Signet Star with primary
issuing carrier capability and thereby generate "reverse flow" business. Under
the reverse flow concept, a reinsurer writes primary business through a
subsidiary or affiliated carrier that is then ceded back to the reinsurer. It
operates as an authorized insurance company in the State of Delaware and will
operate nationwide, as necessary legal and regulatory requirements are met, as
an approved excess and surplus line carrier. Gemini is rated A by A.M. Best.


         StarNet Insurance Company ("StarNet") was acquired by Signet Star in
1998 to write reverse flow business on an admitted basis. Signet Star will seek
to license StarNet broadly to serve as an adjunct to Gemini to write primary
business on an admitted basis nationwide. StarNet is rated A by A.M. Best.


         The Latin American and Caribbean Division was established in 1996 to
write business exclusively in Latin America and the Caribbean. In January 2000,
Signet Star decided to withdraw from this market place, with no new business
being written after February 1, 2000. The Division's net premiums written for
the year ended December 31, 1999 were $21,088,000.

Loss and Loss Adjustment Expense Reserves

         In the property casualty industry, it is not unusual for significant
periods of time to elapse between the occurrence of an insured loss, the report
of the loss to the insurer and the insurer's payment of that loss. To recognize
liabilities for unpaid losses, insurers establish reserves, which is a balance
sheet account representing estimates of future amounts needed to pay claims and
related expenses with respect to insured events which have occurred. The
Company's loss reserves reflect current estimates of the ultimate cost of
closing outstanding claims; other than its excess workers' compensation ("EWC")
business, as discussed below, the Company does not discount its reserves to
estimated present value for financial reporting purposes.


                                       15
<PAGE>   16
         In general, when a claim is reported, claims personnel establish a
"case reserve" for the estimated amount of the ultimate payment. The estimate
represents an informed judgment based on general reserving practices and
reflects the experience and knowledge of the claims personnel regarding the
nature and value of the specific type of claim. Reserves are also established on
an aggregate basis which provide for losses incurred but not yet reported to the
insurer, potential inadequacy of case reserves, the estimated expenses of
settling claims, including legal and other fees and general expenses of
administering the claims adjustment process ("LAE"), and a provision for
potentially uncollectible reinsurance. Each insurance subsidiary's net retention
for each line of insurance is taken into consideration in computation of
ultimate losses.

         In examining reserve adequacy, several factors are considered,
including historical data, legal developments, changes in social attitudes and
economic conditions, including the effects of inflation. The actuarial process
relies on the basic assumption that past experience, adjusted judgmentally for
the effects of current developments and anticipated trends, is an appropriate
basis for predicting future events. Reserve amounts are necessarily based on
management's informed estimates and judgments using data currently available. As
additional experience and other data become available and are reviewed, these
estimates and judgments are revised. This may result in increases or decreases
to reserves for insured events of prior years. The reserving process implicitly
recognizes the impact of inflation and other factors affecting loss costs by
taking into account changes in historical claim patterns and perceived trends.
There is no precise method to evaluate the impact of any specific factor on the
adequacy of reserves, because the ultimate cost of closing claims is influenced
by numerous factors.

         While the methods for establishing the reserves are well tested over
time, some of the major assumptions about anticipated loss emergence patterns
are subject to fluctuation. In particular, high levels of jury verdicts against
insurers, as well as judicial decisions which "re-formulate" policies to expand
coverage to include previously unforeseen theories of liability, e.g., those
regarding pollution and other environmental exposures, have produced
unanticipated claims and increased the difficulty of estimating the loss and
loss adjustment expense reserves provided by the Company.

         Due to the nature of EWC business and the long period of time over
which losses are paid in this line of business, the Company discounts its
liabilities for EWC losses and loss expenses. Discounting liabilities for losses
and loss expenses gives recognition to the time value of money set aside to pay
claims in the future and is intended to appropriately match losses and loss
expenses to income earned on investment securities supporting the liabilities.
The expected losses and loss expense payout pattern subject to discounting was
derived from loss payout experience and is supplemented with data compiled by
insurance companies writing workers' compensation on an excess-of-loss basis.
The expected payout pattern has a very long duration because it reflects the
nature of losses which generally penetrate self-insured retention limits
contained in EWC policies. The Company has limited the expected payout duration
to 30 years in order to introduce an additional level of conservatism into the
discounting process. These liabilities have been discounted using "risk-free"
discount rates determined by reference to the U.S. Treasury yield curve weighted
for EWC premium volume to reflect the seasonality of the anticipated duration of
losses associated with such coverages. The average discount rate for accident
years 1999, 1998, 1997, 1996 and 1995 and prior was approximately 5.90% 5.90%,
5.98%, 5.90% and 5.80%, respectively. The aggregate net discount, after
reflecting the effects of ceded reinsurance, is $186,981,000, $186,964,000,
$189,600,000 and $172,415,000 at December 31, 1999, 1998, 1997 and 1996,
respectively.

         To date, known pollution and environmental claims at the Company's
insurance company subsidiaries have not had a material impact on the Company's
operations. Environmental claims have not materially impacted the Company
because these subsidiaries generally did not insure the larger industrial
companies which are subject to significant environmental exposures.

         The Company's net reserves for losses and loss adjustment expenses
relating to pollution and environmental claims were $30,944,000 and $33,391,000
at December 31, 1999 and 1998, respectively. The Company's gross reserves for
losses and loss adjustment expenses relating to pollution and environmental
claims were $65,966,000 and $69,283,000 at December 31, 1999 and 1998,
respectively. Net incurred losses and loss expenses for reported pollution and
environmental claims were approximately $1,371,000, $2,227,000 and $79,000 in
1999, 1998 and 1997, respectively. Net paid losses and loss expenses were
approximately $3,819,000, $2,614,000 and $2,175,000 in 1999, 1998 and 1997,
respectively. The estimation of these liabilities is subject to significantly
greater than normal variation and uncertainty because it is difficult to make a
reasonable actuarial estimate of these liabilities due to the absence of a
generally accepted actuarial methodology for these exposures and the potential
affect of significant unresolved legal matters, including coverage issues as
well as the cost of litigating the legal issues. Additionally, the determination
of ultimate damages and the final allocation of such damages to financially
responsible parties are highly uncertain.

reserve balances, on a gross of reinsurance basis (dollars in thousands)(1):

       The following table presents the development of net reserves for 1989
through 1999. The top line of the table shows the estimated reserves for unpaid
losses and loss expenses recorded at the balance sheet date for each of the
indicated years. This represents the estimated amount of losses and loss
expenses for claims arising in all prior years that are unpaid at the balance
sheet date, including losses that had been incurred but not yet reported to the
Company. The upper portion of the table shows 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)" represents the aggregate
change in the estimates over all prior years. For example, the 1989 reserves
have developed a $84 million redundancy over ten years. That amount has been
reflected in income over the ten years. The impact on the results of operations
of the past three years of changes in reserve estimates is shown in the
reconciliation tables above.

         It should be noted that the table presents a "run off" of balance sheet
reserves, rather than accident or policy year loss development. Therefore, each
amount in the table includes the effects of changes in reserves for all prior
years. For example, assume a claim that occurred in 1989 is reserved for $2,000
as of December 31, 1989. Assuming this claim was settled for $2,300 in 1999, the
$300 deficiency would appear as a deficiency in each year from 1989 through
1998.

Regulation

         The Company's insurance subsidiaries are subject to varying degrees of
regulation and supervision in the jurisdictions in which they do business, under
statutes which delegate regulatory, supervisory and administrative powers to
state insurance commissioners. This regulation relates to such matters as the
standards of solvency which must be met and maintained; the licensing of
insurers and their agents; the nature of and limitations on investments;
deposits of securities for the benefit of policyholders; approval of policy
forms and premium rates; periodic examination of the affairs of insurance
companies; annual and other reports required to be filed on the financial
condition of insurers or for other purposes; establishment and maintenance of
reserves for unearned premiums and losses; and requirements regarding numerous
other matters. The Company's property casualty subsidiaries, other than E & S
and reinsurance subsidiaries, must file all rates for personal and commercial
insurance with the insurance department of each state in which they operate. The
Company's E & S and reinsurance subsidiaries generally operate free of rate and
form regulation.

         In addition to regulatory supervision of its insurance subsidiaries,
the Company is subject to state statutes governing insurance holding company
systems. Typically, such statutes require the Company periodically to file
information with the state insurance commissioner, including information
concerning its capital structure, ownership, financial condition and general
business operations. Under the terms of applicable state statutes, any person or
entity desiring to purchase more than a specified percentage (commonly 10%) of
the Company's outstanding voting securities would be required to obtain
regulatory approval of the purchase. Under Florida law, which is applicable to
the Company due to its ownership of Carolina, a Florida domiciled insurer, the
acquisition of more than 5% of the Company's capital stock must receive
regulatory approval. Further, state insurance statutes typically place
limitations on the amount of dividends or other distributions payable by
insurance companies in order to protect their solvency. See "Management's
Discussion and Analysis of Financial Condition and Results of
Operations-Liquidity and Capital Resources."

         During the past several years, various regulatory and legislative
bodies adopted or proposed new laws or regulations to deal with the cyclical
nature of the insurance industry, catastrophic events and their effects on
shortage of capacity and pricing. These regulations, which have not had a
material impact on the Company's operations, include (i) the creation of "market
assistance plans" under which insurers are induced to provide certain coverages,
(ii) restrictions on the ability of insurers to cancel certain policies in
mid-term, (iii) advance notice requirements or limitations imposed for certain
policy non-renewals and (iv) limitations upon or decreases in rates permitted to
be charged. The passage of Proposition 103 in the State of California did not
have a material adverse impact on the Company's operations because the Company's
subsidiaries operated in that State primarily on a non-admitted basis. The
non-admitted market in California, however, has been subjected to increased
levels of regulation. Admiral and Nautilus, both of which derive significant
premiums from California, may be adversely impacted by increased regulation
which causes business to remain in the admitted market. Additionally, a number
of states have adopted and others are considering adopting forms of commercial
lines deregulation laws which, depending upon factors such as the relatively
high amount of premium or revenue of an insured, would permit an insurer to
provide insurance without being subject to rate and/or form filing requirements.

         Various state and federal organizations, including Congressional
committees and the National Association of Insurance Commissioners ("NAIC"),
have been conducting reviews into various aspects of the insurance business. The
NAIC has adopted risk based capital ("RBC") requirements that require insurance
companies to calculate and report information under a risk-based formula which
measures statutory capital and surplus needs based on a regulatory definition of
risk in a company's mix of products and its balance sheet. The implementation of
RBC did not affect the operations of the Company's insurance subsidiaries since
all of its subsidiaries have a RBC amount above the authorized control level
RBC, as defined by the NAIC. The NAIC recently completed a process intended to
codify statutory accounting practices for certain insurance enterprises. As a
result of this process, the NAIC will issue a revised statutory accounting
practices and procedures manual, which will be effective January 1, 2001. The
Company has not yet determined the impact that this change will have on the
statutory capital and surplus of its insurance subsidiaries. The NAIC is
considering model laws on commercial lines deregulation. Federal legislation is
being considered which would either abolish or limit the current exemption of
the insurance industry from portions of the antitrust laws, impose direct
federal oversight or federal solvency standards. No assurance can be given that
future legislative or regulatory changes resulting from such activity will not
adversely affect the Company's insurance subsidiaries.



                                       20
<PAGE>   21
         The Gramm-Leach-Bliley Act, or Financial Services Modernization Act of
1999 (the "Act"), was enacted in 1999, significantly affecting the financial
services industry, including insurance companies, banks and securities firms.
The Act modifies federal law to permit the creation of financial holding
companies ("FHCs"), which, as regulated by the Act, can maintain cross-holdings
in insurance companies, banks and securities firms to an extent not previously
allowed. The Act also permits or facilitates certain types of combinations or
affiliations for FHCs. The Act establishes a functional regulatory scheme under
which state insurance departments will maintain primary regulation over
insurance activities, subject to provisions for certain federal preemptions.

         Important provisions of the Act involve requirements for adoption of
(i) multi-state agents' licensing reforms and uniformity requirements and (ii)
privacy protections, giving the states the ability to enact these laws in the
first instance or be preempted. The NAIC is considering adoption of a model law
on privacy. It has also adopted a model law on agents' licensing which has been
enacted or is currently being considered by various state legislatures. It is
not anticipated that the insurance regulatory aspects of the Act will have a
material effect on the operations of the Company.

         The Company's insurance subsidiaries are also subject to assessment by
state guaranty funds when an insurer in that jurisdiction has been judicially
declared insolvent and insufficient funds are available from the liquidated
company to pay policyholders and claimants. The protection afforded under a
state's guaranty fund to policyholders of the insolvent insurer varies from
state to state. Generally, all licensed property casualty insurers are
considered to be members of the fund, and assessments are based upon their pro
rata share of direct written premiums. The NAIC Model Post-Assessment Guaranty
Fund Act, which many states have adopted, limits assessments to an insurer to 2%
of its subject premium and permits recoupment of assessments through rate
setting. Likewise, several states (or underwriting organizations of which the
Company's insurance subsidiaries are required to be members) have limited
assessment authority with regard to deficits in certain lines of business. To
date, assessments have not had a material adverse impact on operations.

         The Company receives funds from its insurance subsidiaries in the form
of dividends and fees for certain management services. Annual dividends in
excess of maximum amounts prescribed by state statutes ("extraordinary
dividends") may not be paid without the approval of the insurance commissioner
of the state in which an insurance subsidiary is domiciled.

Competition

         The property casualty insurance and reinsurance business is
competitive, with over 2,000 insurance companies transacting business in the
United States. The Company competes directly with a large number of these
companies. The Company's strategy in this highly fragmented industry is to seek
specialized areas or geographic regions where its insurance subsidiaries can
gain a competitive advantage by responding quickly to changing market
conditions. Each of the Company's subsidiaries establishes its own pricing
practices. Such practices are based upon a Company-wide philosophy to price
products with the general intent of making an underwriting profit. Competition
in the industry generally changes with profitability.

         The regional property casualty subsidiaries compete with mutual and
other regional stock companies as well as national carriers. Direct writers of
property casualty insurance compete with the regional subsidiaries by writing
insurance through their salaried employees, generally at a lower cost than
through independent agents such as those used by the Company. Also, certain
personal lines have become more competitive due to Internet-based competition.

         Signet Star's competition comes from domestic and foreign reinsurers,
many of which have greater financial resources than Signet Star and which place
their business either on a direct basis or through the broker market.

         The E & S area is a highly specialized segment of the insurance
industry. Admiral and Nautilus compete with other E & S carriers, some of which
are larger and have greater resources than Admiral and Nautilus. Under certain
market conditions, standard carriers may compete for the types of business
written by Admiral and Nautilus. With the implementation of commercial lines
deregulation (see "Regulation") in several states and with many other states in
the process of considering or adopting such laws, competition for "E & S type
risks" might increase significantly. Such standard carriers would under such
deregulation be free to compete with more liberal rate and form requirements. In
addition, there are regional and


                                       21
<PAGE>   22
specialty carriers competing with Admiral and Nautilus when they underwrite
business in their regions or specialties.

         Carolina and Great Divide's competition comes mainly from other
specialty transportation insurers, regional carriers and large national
multi-line companies. Each of Admiral Indemnity, Preferred and Key Risk
Insurance compete with local regional companies as well as national carriers.

         Midwest Employers' competition comes from insurance and reinsurance
companies, some of which have greater financial resources than Midwest
Employers. Most of theses carriers write specific EWC coverage, do not offer
aggregate EWC coverage and tend to focus on risks larger than those targeted by
Midwest Employers. In addition, Midwest Employers competes with other specialty
EWC insurers.

         The Insurance Services Operations face competition from several large
nationally known service organizations as well as local competitors. The
International Operations compete with native insurance operations both large and
small, which may be related to government entities, as well as with branch or
local subsidiaries of multi-national companies.

Employees

         As of March 3, 2000, the Company employed 4,181 persons. Of this
number, the Company's subsidiaries employed 4,131 persons, of whom 2,690 were
executive and administrative personnel and 1,441 were clerical personnel. The
Company employed the remaining 50 persons in its parent company and investment
operations, of whom 36 were executive and administrative personnel and 14 were
clerical personnel.

Other information about the Company's business

         The Company maintains an ongoing interest in acquiring additional
companies and developing new insurance entities, products and packages as
opportunities arise. In addition, the insurance subsidiaries develop new
coverages or lines of business to meet the needs of insureds.

         Seasonal weather variations affect the severity and frequency of losses
sustained by the insurance and reinsurance subsidiaries. Although the effect on
the Company's business of such natural catastrophes as tornadoes, hurricanes,
hailstorms and earthquakes is mitigated by reinsurance, they nevertheless can
have a significant impact on the results of any one or more reporting periods.

         The Company has no customer which accounts for 10 percent or more of
its consolidated revenues.

         Compliance by the Company and its subsidiaries with federal, state and
local provisions which have been enacted or adopted regulating the discharge of
materials into the environment, or otherwise relating to protection of the
environment has not had a material effect upon the capital expenditures,
earnings or competitive position of the Company.

ITEM 2. PROPERTIES

The Company and its subsidiaries own or lease office buildings or office space
suitable to conduct their operations. Such owned property is as follows:

<PAGE>   23
ITEM 3. LEGAL PROCEEDINGS

         Claims under insurance policies written by the Company's insurance
subsidiaries are investigated and settled either by claims adjusters employed by
them, by their independent agents or by independent adjusters. Generally, the
insurance subsidiary employs a staff of claims adjusters at its home office and
at some regional offices. Some independent agents may have the authority to
settle small claims. Independent claims adjusting firms are used to assist in
handling various claims in areas where insurance volume does not warrant the
maintenance of a staff adjuster. If a claim or loss cannot be settled and
results in litigation, the subsidiary generally retains outside counsel.

         At present, neither the Company nor any of its subsidiaries is engaged
in any litigation known to the Company which is expected to have a material
adverse effect upon the Company's business. As is common with property casualty
insurance companies, the Company's subsidiaries are regularly engaged in the
defense of claims arising out of the conduct of the insurance business.

              INDEPENDENT AUDITORS' REPORT ON SCHEDULES AND CONSENT


Board of Directors and Stockholders
W. R. Berkley Corporation


The audits referred to in our report dated February 24, 2000, included the
related financial statement schedules as of December 31, 1999 and 1998
incorporated by reference in the Form 10-K, and for each of the years in the
three-year period ended December 31, 1999. These financial statement schedules
are the responsibility of the Company's management. Our responsibility is to
express an opinion on these financial statement schedules based on our audits.
In our opinion, such 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 Company has
changed its method of accounting for insurance-related assessments in 1999.

We consent to the use of our reports incorporated by reference in the
Registration Statements, (No. 33-95552) and (No. 333-00459) on Form S-3 and (No.
33-7488), (No. 33-88640), (No. 333-33935) and (No. 33-55726) on Form S-8 of W.

Agreement;

         NOW, THEREFORE, in consideration of the mutual agreements, provisions
and covenants contained herein, the parties agree as follows:

                                    ARTICLE 1

                                  DEFINITIONS

         1.1      Certain Defined Terms. The following terms have the following
meanings:

                  "Acquisition" means any transaction or series of related
         transactions for the purpose of or resulting, directly or indirectly,
         in (a) the acquisition of all or substantially all of the assets of a
         Person, or of any business or division of a Person, (b) the acquisition
         of in excess of 50% of the capital stock, partnership interests or
         equity of any Person, or otherwise causing any Person to become a
         Subsidiary, or (c) a merger or consolidation or any other combination
         with another Person (other than a Person that is a Subsidiary) provided

         indirectly, the power to direct or cause the direction of the
         management and policies of the other Person, whether through the
         ownership of voting securities, by contract, or otherwise.

combined Commitments. Within the limits of each Bank's Commitment, and subject
to the other terms and conditions hereof, the Company may borrow under this
Section 2.1, prepay under Section 2.6 and reborrow under this Section 2.1.

         2.2 Loan Accounts. (a) The Loans made by each Bank shall be evidenced
by one or more loan accounts or records maintained by such Bank in the ordinary
course of business. The loan accounts or records maintained by the Agent and
each Bank shall be conclusive absent manifest error of the amount of the Loans
made by the Banks to the Company and the interest and payments thereon. Any
failure so to record or any error in doing so shall not, however, limit or
otherwise affect the obligation of the Company hereunder to pay any amount owing
with respect to the Loans.

                      (b)     Upon the request of any Bank made through the
Agent, the Loans made by such Bank may be evidenced by one or more Notes,
instead of loan accounts. Each such Bank shall endorse on the schedules annexed
to its Note(s) the date, amount and maturity of each Loan made by it and the
amount of each payment of principal made by the Company with respect thereto.
Each such Bank is irrevocably authorized by the Company to endorse its Note(s)
and each Bank's record shall be conclusive absent manifest error; provided,
however, that the failure of a Bank to make, or an error in making, a notation
thereon with respect to any Loan shall not limit or otherwise affect the
obligations of the Company hereunder or under any such Note to such Bank.

         2.3 Procedure for Borrowing. (a) Each Borrowing shall be made upon the
Company's irrevocable written notice delivered to the Agent in the form of a
Notice of Borrowing (which notice must be received by the Agent prior to 9:00
a.m. (San Francisco time) (i) three Business Days prior to the requested
Borrowing Date, in the case of Offshore Rate Loans; and (ii) on the requested
Borrowing Date, in the case of Base Rate Loans, specifying:

                                        (A) the amount of the Borrowing, which
                      shall be in an aggregate minimum amount of $5,000,000 or
                      any multiple of $1,000,000 in excess thereof;

                                        (B) the requested Borrowing Date, which
                      shall be a Business Day;

                                        (C) the Type of Loans comprising the
                      Borrowing; and

                                        (D) if applicable, the duration of the
                      Interest Period applicable to such Loans included in such
                      notice. If the Notice of Borrowing fails to specify the
                      duration of the Interest Period for any

                                      -18-
<PAGE>   24
                      Borrowing comprised of Offshore Rate Loans, such Interest
                      Period shall be three months.

                      (b)     The Agent will promptly notify each Bank of its
receipt of any Notice of Borrowing and of the amount of such Bank's Pro Rata
Share of that Borrowing.

                      (c)     Each Bank will make the amount of its Pro Rata
Share of each Borrowing available to the Agent for the account of the Company at
the Agent's Payment Office by 11:00 a.m. (San Francisco time) on the Borrowing
Date requested by the Company in funds immediately available to the Agent. The
proceeds of all such Loans will then be made available to the Company by the
Agent at such office by crediting the account of the Company on the books of
BofA with the aggregate of the amounts made available to the Agent by the Banks
or by wire transfer in accordance with written instructions provided to the
Agent by the Company, of like funds as received by the Agent.

                      (d)     After giving effect to any Borrowing, there may
not be more than five different Interest Periods in effect.

         2.4  Conversion and Continuation Elections.  (a)  The Company
may, upon irrevocable written notice to the Agent in accordance
with subsection 2.4(b):

                              (i)  elect, as of any Business Day, in the case of
         Base Rate Loans, or as of the last day of the applicable Interest
         Period, in the case of Offshore Rate Loans, to convert any such Loans
         (or any part thereof in an amount not less than $5,000,000, or that is
         in an integral multiple of $1,000,000 in excess thereof) into Loans of
         the other Type; or

                              (ii)  elect, as of the last day of the applicable
         Interest Period, to continue any Loans having Interest Periods expiring
         on such day (or any part thereof in an amount not less than $5,000,000,
         or that is in an integral multiple of $1,000,000 in excess thereof);

provided, that if at any time the aggregate amount of Offshore Rate Loans in
respect of any Borrowing is reduced, by payment, prepayment, or conversion of
part thereof to be less than $1,000,000, such Offshore Rate Loans shall
automatically convert into Base Rate Loans, and on and after such date the right
of the Company to continue such Loans as, and convert such Loans into, Offshore
Rate Loans shall terminate.

                      (b)     The Company shall deliver a Notice of Conversion/
Continuation to be received by the Agent not later than 9:00 a.m. (San Francisco
time) at least (i) three Business Days in advance of the Conversion/Continuation
Date, if the Loans are to be converted

                                      -19-
<PAGE>   25
into or continued as Offshore Rate Loans; and (ii) on the Conversion/
Continuation Date, if the Loans are to be converted into Base Rate
Loans, specifying:

                                    (A) the proposed Conversion/Continuation
                           Date;

                                    (B) the aggregate amount of Loans to be
                           converted or renewed;

                                    (C) the Type of Loans resulting from the
                           proposed conversion or continuation; and

                                    (D) if applicable, the duration of the
                           requested Interest Period.

                      (c)     If upon the expiration of any Interest Period
applicable to Offshore Rate Loans, the Company has failed to select timely a new
Interest Period to be applicable to such Offshore Rate Loans, or if any Default
or Event of Default then exists, the Company shall be deemed to have elected to
convert such Offshore Rate Loans into Base Rate Loans effective as of the
expiration date of such Interest Period.

                      (d)     The Agent will promptly notify each Bank of its
receipt of a Notice of Conversion/Continuation, or, if no timely notice is
provided by the Company, the Agent will promptly notify each Bank of the details
of any automatic conversion. All conversions and continuations shall be made
ratably according to the respective outstanding principal amounts of the Loans
with respect to which the notice was given held by each Bank.

                      (e)     Unless the Required Banks otherwise agree, during
the existence of a Default or Event of Default, the Company may not elect to
have a Loan converted into or continued as an Offshore Rate Loan.

                      (f)     After giving effect to any conversion or
continuation of Loans, there may not be more than five different Interest
Periods in effect.

         2.5 Voluntary Termination or Reduction of Commitments. The Company may,
upon not less than five Business Days' prior notice to the Agent, terminate the
Commitments, or permanently reduce the Commitments by an aggregate minimum
amount of $5,000,000 or any multiple of $1,000,000 in excess thereof; unless,
after giving effect thereto and to any prepayments of Loans made on the
effective date thereof, the then-outstanding principal amount of the Loans would
exceed the amount of the combined Commitments then in effect. Once reduced in
accordance with this Section, the Commitments may not be increased. Any
reduction of the Commitments

                                      -20-
<PAGE>   26
shall be applied to each Bank according to its Pro Rata Share. All accrued
commitment fees to, but not including the effective date of any reduction or
termination of Commitments, shall be paid on the effective date of such
reduction or termination.

         2.6 Optional Prepayments. Subject to Section 3.4, the Company may, at
any time or from time to time, upon not less than three Business Days'
irrevocable notice to the Agent, ratably prepay Loans in whole or in part, in
minimum aggregate amounts of $5,000,000 or any multiple of $1,000,000 in excess
thereof. Such notice of prepayment shall specify the date and amount of such
prepayment and the Type(s) of Loans to be prepaid. The Agent will promptly
notify each Bank of its receipt of any such notice, and of such Bank's Pro Rata
Share of such prepayment. If such notice is given by the Company, the Company
shall make such prepayment and the payment amount specified in such notice shall
be due and payable on the date specified therein, together with accrued interest
to each such date on the amount prepaid and any amounts required pursuant to
Section 3.4.

         2.7 Repayment. The Company shall repay to the Banks on the Revolving
Termination Date the aggregate principal amount of Loans outstanding on such
date.

         2.8 Interest. (a) Each Loan shall bear interest on the outstanding
principal amount thereof from the applicable Borrowing Date at a rate per annum
equal to the Offshore Rate plus the Applicable Margin or the Base Rate, plus the
Applicable Margin, as the case may be (and subject to the Company's right to
convert to other Types of Loans under Section 2.4).

                     (b)       Interest on each Loan shall be paid in arrears on
each Interest Payment Date. Interest shall also be paid on the date of any
prepayment of Offshore Rate Loans under Section 2.6 for the portion of the Loans
so prepaid and upon payment (including prepayment) in full thereof and, during
the existence of any Event of Default, interest shall be paid on demand of the
Agent at the request or with the consent of the Required Banks.

                     (c)       Notwithstanding subsection (a) of this Section,
while any Event of Default exists or after acceleration, the Company shall pay
interest (after as well as before entry of judgment thereon to the extent
permitted by law) on the principal amount of all outstanding Loans, at a rate
per annum which is determined by adding 2% per annum to the interest rate
calculated pursuant to subsection (a) above for such Loans; provided, however,
that, on and after the expiration of any Interest Period applicable to any
Offshore Rate Loan outstanding on the date of occurrence of such Event of
Default or acceleration, the principal amount of such Loan shall, during the
continuation of such Event of Default or

                                      -21-
<PAGE>   27
after acceleration, bear interest at a rate per annum equal to the Base Rate
plus the Applicable Margin for Base Rate Loans plus 2%.

                     (d)  Anything herein to the contrary notwithstanding,
the obligations of the Company to any Bank hereunder shall be subject to the
limitation that payments of interest shall not be required for any period for
which interest is computed hereunder, to the extent (but only to the extent)
that contracting for or receiving such payment by such Bank would be contrary to
the provisions of any law applicable to such Bank limiting the highest rate of
interest that may be lawfully contracted for, charged or received by such Bank,
and in such event the Company shall pay such Bank interest at the highest rate
permitted by applicable law.

         2.9 Fees. (a) Arrangement, Agency Fees. The Company shall pay an
arrangement fee to the Arranger for the Arranger's own account, and shall pay an
agency fee to the Agent for the Agent's own account, as required by the letter
agreement ("Fee Letter") between the Company and the Arranger and Agent dated
May 26, 1999.

                     (b) Facility Fees.  The Company shall pay to the Agent
for the account of each Bank a facility fee on the average daily amount of such
Bank's Commitment (whether or not used), computed on a quarterly basis in
arrears on the last Business Day of each calendar quarter based upon the daily
amount of the Commitments for that quarter as calculated by the Agent, equal to
the Applicable Facility Fee Rate per annum. Such facility fee shall accrue from
the date hereof to the Revolving Termination Date and shall be due and payable
quarterly in arrears on the last Business Day of each calendar quarter
commencing on the first such date after the date hereof through the Revolving
Termination Date, with the final payment to be made on the Revolving Termination
Date; provided that, in connection with any reduction or termination of
Commitments under Section 2.5, the accrued facility fee calculated for the
period ending on such date shall also be paid on the date of such reduction or
termination, with the following quarterly payment being calculated on the basis
of the period from such reduction or termination date to such quarterly payment
date. The facility fees provided in this subsection shall accrue at all times
after the above-mentioned commencement date, including at any time during which
one or more conditions in Article IV are not met.

                     (c)       Utilization Fees.  The Company shall pay to the
Agent for the account of each Bank a utilization fee on the actual daily
outstanding principal amount of the Loans for any day on which the outstanding
principal amount of the Loans exceeds one-half (1/2) of the aggregate
Commitments computed on a quarterly basis in arrears on the last Business Day of
each calendar quarter based upon the daily amount of the Commitments and
outstanding Loans for that quarter as calculated by the Agent, equal to the
Applicable Utilization Fee Rate per annum. Such utilization fee

                                      -22-
<PAGE>   28
shall be due and payable quarterly in arrears on the last Business Day of each
calendar quarter in which such fee shall accrue commencing on the first such
date after the date hereof through the Revolving Termination Date, with the
final payment to be made on the Revolving Termination Date.

         2.10 Computation of Fees and Interest. (a) All computations of interest
for Base Rate Loans when the Base Rate is determined by BofA's "prime rate"
shall be made on the basis of a year of 365 or 366 days, as the case may be, and
actual days elapsed. All other computations of fees and interest shall be made
on the basis of a 360-day year and actual days elapsed (which results in more
interest being paid than if computed on the basis of a 365-day year). Interest
and fees shall accrue during each period during which interest or such fees are
computed from the first day thereof to the last day thereof.

                     (b)       Each determination of an interest rate by the
Agent shall be conclusive and binding on the Company and the Banks in the
absence of manifest error.

         2.11 Payments by the Company. (a) All payments to be made by the
Company shall be made without set-off, recoupment or counterclaim. Except as
otherwise expressly provided herein, all payments by the Company shall be made
to the Agent for the account of the Banks at the Agent's Payment Office, and
shall be made in dollars and in immediately available funds, no later than 11:00
a.m. (San Francisco time) on the date specified herein. The Agent will promptly
distribute to each Bank its Pro Rata Share (or other applicable share as
expressly provided herein) of such payment in like funds as received. Any
payment received by the Agent later than 11:00 a.m. (San Francisco time) shall
be deemed to have been received on the following Business Day and any applicable
interest or fee shall continue to accrue.

                     (b)       Subject to the provisions set forth in the
definition of "Interest Period" herein, whenever any payment is due on a day
other than a Business Day, such payment shall be made on the following Business
Day, and such extension of time shall in such case be included in the
computation of interest or fees, as the case may be.

                     (c)       Unless the Agent receives notice from the Company
prior to the date on which any payment is due to the Banks that the Company will
not make such payment in full as and when required, the Agent may assume that
the Company has made such payment in full to the Agent on such date in
immediately available funds and the Agent may (but shall not be so required), in
reliance upon such assumption, distribute to each Bank on such due date an
amount equal to the amount then due such Bank. If and to the extent the Company
has not made such payment in full to the Agent, each Bank

                                      -23-
<PAGE>   29
shall repay to the Agent on demand such amount distributed to such Bank,
together with interest thereon at the Federal Funds Rate for each day from the
date such amount is distributed to such Bank until the date repaid.

         2.12 Payments by the Banks to the Agent. (a) Unless the Agent receives
notice from a Bank on or prior to the Closing Date or, with respect to any
Borrowing after the Closing Date, at least one Business Day prior to the date of
such Borrowing, that such Bank will not make available as and when required
hereunder to the Agent for the account of the Company the amount of that Bank's
Pro Rata Share of the Borrowing, the Agent may assume that each Bank has made
such amount available to the Agent in immediately available funds on the
Borrowing Date and the Agent may (but shall not be so required), in reliance
upon such assumption, make available to the Company on such date a corresponding
amount. If and to the extent any Bank shall not have made its full amount
available to the Agent in immediately available funds and the Agent in such
circumstances has made available to the Company such amount, that Bank shall on
the Business Day following such Borrowing Date make such amount available to the
Agent, together with interest at the Federal Funds Rate for each day during such
period. A notice of the Agent submitted to any Bank with respect to amounts
owing under this subsection (a) shall be conclusive, absent manifest error. If
such amount is so made available, the principal portion of such payment to the
Agent shall constitute such Bank's Loan on the date of Borrowing for all
purposes of this Agreement. If such amount is not made available to the Agent on
the Business Day following the Borrowing Date, the Agent will notify the Company
of such failure to fund and, upon demand by the Agent, the Company shall pay
such principal portion of such payment to the Agent for the Agent's account,
together with interest thereon for each day elapsed since the date of such
Borrowing, at a rate per annum equal to the interest rate applicable at the time
to the Loans comprising such Borrowing.

                     (b)       The failure of any Bank to make any Loan on any
Borrowing Date shall not relieve any other Bank of any obligation hereunder to
make a Loan on such Borrowing Date, but no Bank shall be responsible for the
failure of any other Bank to make the Loan to be made by such other Bank on any
Borrowing Date.

         2.13 Sharing of Payments, Etc. If, other than as expressly provided
elsewhere herein, any Bank shall obtain on account of the Loans made by it any
payment (whether voluntary, involuntary, through the exercise of any right of
set-off, or otherwise) in excess of its Pro Rata Share, such Bank shall
immediately (a) notify the Agent of such fact, and (b) purchase from the other
Banks such participations in the Loans made by them as shall be necessary to
cause such purchasing Bank to share the excess payment pro rata with each of
them; provided, however, that if all or any

                                      -24-
<PAGE>   30
portion of such excess payment is thereafter recovered from the purchasing Bank,
such purchase shall to that extent be rescinded and each other Bank shall repay
to the purchasing Bank the purchase price paid therefor, together with an amount
equal to such paying Bank's ratable share (according to the proportion of (i)
the amount of such paying Bank's required repayment to (ii) the total amount so
recovered from the purchasing Bank) of any interest or other amount paid or
payable by the purchasing Bank in respect of the total amount so recovered. The
Company agrees that any Bank so purchasing a participation from another Bank
may, to the fullest extent permitted by law, exercise all its rights of payment
(including the right of set-off, but subject to Section 10.10) with respect to
such participation as fully as if such Bank were the direct creditor of the
Company in the amount of such participation. The Agent will keep records (which
shall be conclusive and binding in the absence of manifest error) of
participations purchased under this Section and will in each case notify the
Banks following any such purchases or repayments.

         2.14 Termination Date. The Company may request an extension of the
Scheduled Termination Date by submitting a request for an extension to the Agent
(an "Extension Request") no more than 60 days or less than 45 days prior to the
then effective Scheduled Termination Date. The Extension Request must specify
the new Scheduled Termination Date requested by the Company and the date (which
must be at least 30 days after the Extension Request is delivered to the Agent)
as of which the Banks must respond to the Extension Request (the "Response
Date"). The new Scheduled Termination Date shall be no more than 364 days after
the Scheduled Termination Date in effect at the time the Extension Request is
received, including the Scheduled Termination Date as one of the days in the
calculation of the days elapsed. Promptly upon receipt of an Extension Request,
the Agent shall notify each Bank of the contents thereof and shall request each
Bank to approve the Extension Request. Each Bank approving the Extension Request
shall deliver its written consent no later than the Response Date. If the
consent of each of the Banks is received by the Agent, the Scheduled Termination
Date specified in the Extension Request shall become effective on the existing
Scheduled Termination Date and the Agent shall promptly notify the Company and
each Bank of the new Scheduled Termination Date. If any Bank shall not so
consent, the Scheduled Termination Date shall not be extended.

         2.15 Increase of Commitments. The Company may from time to time, by
notice to the Agent, request that the total aggregate Commitments (the "Total
Aggregate Commitment") be increased to an amount not exceeding $100,000,000.
Each such notice shall set forth the requested amount of the increase in the
Total Aggregate Commitment and the date on which such increase is to become
effective. The increase in the Total Aggregate Commitment may be assumed by any
Bank or any other financial institution agreed to by

                                      -25-
<PAGE>   31
the Company and the Agent (any such Bank or other financial institution being
called an "Augmenting Bank") and shall be effective upon the consent of the
Company and the Augmenting Bank.

         Upon the effectiveness of any increase pursuant to this Section 2.15 of
the Total Aggregate Commitment and any resulting adjustment in the Pro Rata
Shares, the Banks and the Augmenting Banks will purchase from each other and
sell to each other outstanding Loans sufficient to cause the outstanding Loans
of each Bank and Augmenting Bank to equal its Pro Rata Share (as so adjusted) of
the aggregate principal amount of the Total Aggregate Commitment. Such purchase
and sale shall be made pursuant to Section 10.8 except that no minimum amount
shall be required, no processing fee shall be charged and, if any Bank shall
suffer a loss or incur an expense as a result of the effectiveness of such
purchase or sale the Company shall pay such Bank the amount of such loss or
expense. Each such Bank shall furnish the Company with a certificate setting
forth the basis for determining the amount to be paid to it hereunder.


                                   ARTICLE III

                     TAXES, YIELD PROTECTION AND ILLEGALITY

         3.1 Taxes. (a) Any and all payments by the Company to each Bank or the
Agent under this Agreement and any other Loan Document shall be made free and
clear of, and without deduction or withholding for any Taxes. In addition, the
Company shall pay all Other Taxes.

                     (b)       The Company agrees to indemnify and hold harmless
each Bank and the Agent for the full amount of Taxes or Other Taxes (including
any Taxes or Other Taxes imposed by any jurisdiction on amounts payable under
this Section) paid by the Bank or the Agent and any liability (including
penalties, interest, additions to tax and expenses) arising therefrom or with
respect thereto, whether or not such Taxes or Other Taxes were correctly or
legally asserted. Payment under this indemnification shall be made within 30
days after the date the Bank or the Agent makes written demand therefor.

                     (c)       If the Company shall be required by law to deduct
or withhold any Taxes or Other Taxes from or in respect of any sum payable
hereunder to any Bank or the Agent, then:

                               (i)  the sum payable shall be increased as
         necessary so that after making all required deductions and withholdings
         (including deductions and withholdings applicable to additional sums
         payable under this Section) such Bank or the Agent, as the case may be,
         receives an amount equal to the

                                      -26-
<PAGE>   32
         sum it would have received had no such deductions or withholdings been
         made;

                               (ii) the Company shall make such deductions and
         withholdings;

                               (iii)  the Company shall pay the full amount
         deducted or withheld to the relevant taxing authority or other
         authority in accordance with applicable law; and

                               (iv) the Company shall also pay to each Bank or
         the Agent for the account of such Bank, at the time interest is paid,
         all additional amounts which the respective Bank specifies as necessary
         to preserve the after-tax yield the Bank would have received if such
         Taxes or Other Taxes had not been imposed.

                     (d)       Within 30 days after the date of any payment by
the Company of Taxes or Other Taxes, the Company shall furnish the Agent the
original or a certified copy of a receipt evidencing payment thereof, or other
evidence of payment satisfactory to the Agent.

                     (e)       If the Company is required to pay additional
amounts to any Bank or the Agent pursuant to subsection (c) of this Section,
then such Bank shall use reasonable efforts (consistent with legal and
regulatory restrictions) to change the jurisdiction of its Lending Office so as
to eliminate any such additional payment by the Company which may thereafter
accrue, if such change in the judgment of such Bank is not otherwise
disadvantageous to such Bank.

         3.2 Illegality. (a) If any Bank determines that the introduction of any
Requirement of Law, or any change in any Requirement of Law, or in the
interpretation or administration of any Requirement of Law, has made it
unlawful, or that any central bank or other Governmental Authority has asserted
that it is unlawful, for any Bank or its applicable Lending Office to make
Offshore Rate Loans, then, on notice thereof by the Bank to the Company through
the Agent, any obligation of that Bank to make Offshore Rate Loans shall be
suspended until the Bank notifies the Agent and the Company that the
circumstances giving rise to such determination no longer exist.

                     (b)       If a Bank determines that it is unlawful to
maintain any Offshore Rate Loan, the Company shall, upon its receipt of notice
of such fact and demand from such Bank (with a copy to the Agent), prepay in
full such Offshore Rate Loans of that Bank then outstanding, together with
interest accrued thereon and amounts required under Section 3.4, either on the
last day of the Interest Period thereof, if the Bank may lawfully continue to

                                      -27-
<PAGE>   33
maintain such Offshore Rate Loans to such day, or immediately, if the Bank may
not lawfully continue to maintain such Offshore Rate Loan. If the Company is
required to so prepay any Offshore Rate Loan, then concurrently with such
prepayment, the Company shall borrow from the affected Bank, in the amount of
such repayment, a Base Rate Loan.

         3.3 Increased Costs and Reduction of Return. (a) If any Bank determines
that, due to either (i) the introduction of or any change (other than any change
by way of imposition of or increase in reserve requirements included in the
calculation of the Offshore Rate) in or in the interpretation of any law or
regulation or (ii) the compliance by that Bank with any guideline or request
from any central bank or other Governmental Authority (whether or not having the
force of law), there shall be any increase in the cost to such Bank of agreeing
to make or making, funding or maintaining any Offshore Rate Loans, then the
Company shall be liable for, and shall from time to time, upon demand (with a
copy of such demand to be sent to the Agent), pay to the Agent for the account
of such Bank, additional amounts as are sufficient to compensate such Bank for
such increased costs.

                     (b)       If any Bank shall have determined that (i) the
introduction of any Capital Adequacy Regulation, (ii) any change in any Capital
Adequacy Regulation, (iii) any change in the interpretation or administration of
any Capital Adequacy Regulation by any central bank or other Governmental
Authority charged with the interpretation or administration thereof, or (iv)
compliance by the Bank (or its Lending Office) or any corporation controlling
the Bank with any Capital Adequacy Regulation, affects or would affect the
amount of capital required or expected to be maintained by the Bank or any
corporation controlling the Bank and (taking into consideration such Bank's or
such corporation's policies with respect to capital adequacy and such Bank's
desired return on capital) determines that the amount of such capital is
increased as a consequence of its Commitment, loans, credits or obligations
under this Agreement, then, upon demand of such Bank to the Company through the
Agent, the Company shall pay to the Bank, from time to time as specified by the
Bank, additional amounts sufficient to compensate the Bank for such increase.

         3.4 Funding Losses. The Company shall reimburse each Bank and hold each
Bank harmless from any loss or expense which the Bank may sustain or incur as a
consequence of:

                     (a)       the failure of the Company to make on a timely
basis any payment of principal of any Offshore Rate Loan;

                     (b)       the failure of the Company to borrow, continue or
convert a Loan after the Company has given (or is deemed to have

                                      -28-
<PAGE>   34
given) a Notice of Borrowing or a Notice of Conversion/Continuation;

                     (c)       the failure of the Company to make any prepayment
in accordance with any notice delivered under Section 2.6;

                     (d)       the prepayment or other payment (including after
acceleration thereof) of an Offshore Rate Loan on a day that is not
the last day of the relevant Interest Period; or

                     (e)       the automatic conversion under Section 2.4 of any
Offshore Rate Loan to a Base Rate Loan on a day that is not the
last day of the relevant Interest Period;

including any such loss or expense arising from the liquidation or reemployment
of funds obtained by it to maintain its Offshore Rate Loans or from fees payable
to terminate the deposits from which such funds were obtained. For purposes of
calculating amounts payable by the Company to the Banks under this Section and
under subsection 3.3(a), each Offshore Rate Loan made by a Bank (and each
related reserve, special deposit or similar requirement) shall be conclusively
deemed to have been funded at the LIBOR used in determining the Offshore Rate
for such Offshore Rate Loan by a matching deposit or other borrowing in the
interbank eurodollar market for a comparable amount and for a comparable period,
whether or not such Offshore Rate Loan is in fact so funded.

         3.5 Inability to Determine Rates. If the Required Banks determine that
for any reason adequate and reasonable means do not exist for determining the
Offshore Rate for any requested Interest Period with respect to a proposed
Offshore Rate Loan, or that the Offshore Rate applicable pursuant to subsection
2.8(a) for any requested Interest Period with respect to a proposed Offshore
Rate Loan does not adequately and fairly reflect the cost to such Banks of
funding such Loan, the Agent will promptly so notify the Company and each Bank.
Thereafter, the obligation of the Banks to make or maintain Offshore Rate Loans
hereunder shall be suspended until the Agent upon the instruction of the
Required Banks revokes such notice in writing. Upon receipt of such notice, the
Company may revoke any Notice of Borrowing or Notice of Conversion/Continuation
then submitted by it. If the Company does not revoke such Notice, the Banks
shall make, convert or continue the Loans, as proposed by the Company, in the
amount specified in the applicable notice submitted by the Company, but such
Loans shall be made, converted or continued as Base Rate Loans instead of
Offshore Rate Loans.

         3.6 Certificates of Banks. Any Bank claiming reimbursement or
compensation under this Article III shall deliver to the Company (with a copy to
the Agent) a certificate setting forth in reasonable detail the amount payable
to the Bank hereunder and such

                                      -29-
<PAGE>   35
certificate shall be conclusive and binding on the Company in the absence of
manifest error.

         3.7 Survival. The agreements and obligations of the Company in this
Article III shall survive the payment of all other Obligations.


                                   ARTICLE IV

                                    ARTICLE V

                         REPRESENTATIONS AND WARRANTIES

         The Company represents and warrants to the Agent and each Bank that:

         5.1  Corporate Existence and Power.  The Company and each of its
Insurance Subsidiaries:

                (a) is a corporation duly organized, validly existing and in
good standing under the laws of the jurisdiction of its incorporation or
domicile;

                (b) has the power and authority and all governmental licenses,
authorizations, consents, certificates of authority and approvals (i) to own its
assets and carry on its business, and (ii) in the case of the Company, to
execute, deliver, and perform its obligations under the Loan Documents;

                (c) is duly qualified or, in the case of any Insurance
Subsidiary, licensed as a foreign corporation or as a foreign insurance
corporation, as the case may be, and is in good standing under the laws of each
jurisdiction where its ownership, lease or operation of property or the conduct
of its business requires such qualification or license; and

                (d) is in compliance with all Requirements of Law; except, in
each case referred to in clause (b) (i), clause(c) or clause (d), to the extent
that the failure to do so could not reasonably be expected to have a Material
Adverse Effect.

         5.2 Corporate Authorization; No Contravention. The execution, delivery
and performance by the Company of this Agreement and each other Loan Document to
which the Company is party, have been duly authorized by all necessary corporate
action, and do not:

                     (a)       contravene the terms of any of the Company's
Organization Documents;

                     (b)       conflict with or result in any breach or
contravention of, or the creation of any Lien under, any document evidencing any
Contractual Obligation to which the Company is a party or any order, injunction,
writ or decree of any Governmental Authority to which the Company or its
property is subject; or

                                      -32-
<PAGE>   38
                     (c)       violate any Requirement of Law.

         5.3 Governmental Authorization. No approval, consent, exemption,
authorization, or other action by, or notice to, or filing with, any
Governmental Authority is necessary or required in connection with the
execution, delivery or performance by, or enforcement against, the Company of
this Agreement or any other Loan Document.

         5.4 Binding Effect. This Agreement and each other Loan Document to
which the Company is a party constitute the legal, valid and binding obligations
of the Company, enforceable against the Company in accordance with their
respective terms, except as enforceability may be limited by applicable
bankruptcy, insolvency, or similar laws affecting the enforcement of creditors'
rights generally or by equitable principles relating to enforceability.

         5.5 Litigation. There are no actions, suits, proceedings, claims or
disputes pending, or to the best knowledge of the Company, threatened or
contemplated, at law, in equity, in arbitration or before any Governmental
Authority, against the Company, or its Subsidiaries or any of their respective
properties which:

                     (a)       purport to affect or pertain to this Agreement or
any other Loan Document, or any of the transactions contemplated
hereby or thereby; or

                     (b)       would reasonably be expected to have a Material
Adverse Effect. No injunction, writ, temporary restraining order or any order of
any nature has been issued by any court or other Governmental Authority
purporting to enjoin or restrain the execution, delivery or performance of this
Agreement or any other Loan Document, or directing that the transactions
provided for herein or therein not be consummated as herein or therein provided.

         5.6 No Default. No Default or Event of Default exists or would result
from the incurring of any Obligations by the Company. As of the Closing Date,
neither the Company nor any Subsidiary is in default under or with respect to
any Contractual Obligation in any respect which, individually or together with
all such defaults, could reasonably be expected to have a Material Adverse
Effect, or that would, if such default had occurred after the Closing Date,
create an Event of Default under subsection 8.1(e).

         5.7 ERISA Compliance. Set forth on Schedule 5.7 is a list of all
welfare plans and all pension plans, within the meaning of sections 3(1) and (2)
of ERISA, respectively, which, to the knowledge of the Company, are maintained
with respect to employees of the Company or its Subsidiaries. Also set forth in
Schedule 5.7 is a list of all Multiemployer Plans, all Welfare Plans and all

                                      -33-
<PAGE>   39
Plans which the Company has adopted or expects to adopt. All required
contributions to such Multiemployer Plans, Welfare Plans and Plans have been
made, and no event has occurred with respect to any of the foregoing that would
reasonably be expected to result in the incurrence by the Company or any of its
Subsidiaries of any material liability, fine or penalty. No entity in the
Controlled Group has initiated any steps to withdraw from any Plan, or terminate
any Plan under a distress termination.

         5.8 Use of Proceeds; Margin Regulations. The proceeds of the Loans are
to be used solely for the purposes set forth in and permitted by Section 6.12
and Section 7.5. Neither the Company nor any Subsidiary is generally engaged in
the business of purchasing or selling Margin Stock or extending credit for the
purpose of purchasing or carrying Margin Stock in any manner that would result
in a violation by the Company or any Subsidiary of Regulation T, U or X of the
FRB.

         5.9 Title to Properties. The Company and each of the Insurance
Subsidiaries have good and marketable title to all material properties and
assets owned by them free and clear of all Liens except for such Liens that
could not, individually or in the aggregate, have a Material Adverse Effect. All
of the leases and subleases material to the business of the Company and the
Insurance Subsidiaries, under which either the Company or any of the Insurance
Subsidiaries holds properties, are in full force and effect, and neither the
Company nor any of the Insurance Subsidiaries is in default in respect of any of
the terms or provisions of any of such leases or subleases, the effect of which
would reasonably be expected to have a Material Adverse Effect. The Company has
no notice of any material claim of any kind which has been asserted by anyone
adverse either to the Company's or any of its Insurance Subsidiaries' rights as
lessee or sublessee under any of the leases or subleases mentioned above, or
affecting or questioning the Company's or any of its Insurance Subsidiaries'
rights to the continued possession of the leased or subleased premises under any
such lease or sublease, which if determined adversely, would reasonably be
expected to have a Material Adverse Effect.

         5.10 Taxes. The Company and its Subsidiaries have filed all Federal and
other material tax returns and reports required to be filed, and have paid all
Federal and other material taxes, assessments, fees and other governmental
charges levied or imposed upon them or their properties, income or assets
otherwise due and payable, except those which are being contested in good faith
by appropriate proceedings and for which adequate reserves have been provided in
accordance with GAAP. There is no proposed tax assessment against the Company or
any Subsidiary that would, if made, have a Material Adverse Effect.


                                      -34-
<PAGE>   40
         5.11 Financial Condition. The audited consolidated balance sheet of the
Company and its Subsidiaries dated December 31, 1998, and the unaudited
consolidated balance sheet of the Company and its Subsidiaries dated September
30, 1999, and the related consolidated statements of income or operations and
cash flows for the fiscal year and quarter, respectively, ended on such dates:
(i) were prepared in accordance with GAAP consistently applied throughout the
period covered thereby, except as otherwise expressly noted therein, subject to
ordinary, good faith year end audit adjustments; and (ii) fairly present the
consolidated financial condition of the Company and its Subsidiaries as of the
date thereof and results of operations for the period covered thereby. Since
December 31, 1998, there has been no Material Adverse Effect except as may be
set forth in reports filed by the Company with the SEC after December 31, 1998
and prior to the date of this Agreement.

         5.12 Environmental Matters. The Company's and its Subsidiaries'
business, operations and properties are conducted and maintained in all material
respects in compliance with Environmental Laws.

         5.13 Regulated Entities. None of the Company, any Person controlling
the Company, or any Subsidiary, is an "Investment Company" within the meaning of
the Investment Company Act of 1940. The Company is not subject to regulation
under the Public Utility Holding Company Act of 1935, the Federal Power Act, the
Interstate Commerce Act, any state public utilities code, or any other Federal
or state statute or regulation limiting its ability to incur Indebtedness.

         5.14 No Burdensome Restrictions. Neither the Company nor any Subsidiary
is a party to or bound by any Contractual Obligation, or subject to any
restriction in any Organization Document, or any Requirement of Law, which could
reasonably be expected to have a Material Adverse Effect.

         5.15 Copyrights, Patents, Trademarks and Licenses, etc. The Company and
the Insurance Subsidiaries own or possess, or can acquire on reasonable terms,
adequate trademarks, service marks and trade names necessary to conduct the
business now operated by them, and neither the Company nor any of the Insurance
Subsidiaries has received any notice of infringement of or conflict with
asserted rights of others with respect to any trademarks, service marks or trade
names which, singly or in the aggregate, if the subject of an unfavorable
decision, ruling or finding, would reasonably be expected to have a Material
Adverse Effect.

         5.16 Subsidiaries. As of the Closing Date, the Company has no
Significant Subsidiaries, as defined in Rule 12b-2 under the Exchange Act, other
than as set forth in Exhibit 21 of the

                                      -35-
<PAGE>   41
Company's Annual Report on Form 10-K for its fiscal year ended December 31, 1998
and has no equity investments in any other corporation or entity other than
wholly owned Subsidiaries and other than those specifically disclosed in
Schedule 5.16.

         5.17 Insurance. The properties of the Company and its Insurance
Subsidiaries are insured with financially sound and reputable insurance
companies not Affiliates of the Company, in such amounts, with such deductibles
and covering such risks as are customarily carried by companies engaged in
similar businesses and owning similar properties in localities where the Company
or such Insurance Subsidiary operates.

         5.18 Full Disclosure. None of the representations or warranties made by
the Company in the Loan Documents as of the date such representations and
warranties are made or deemed made, and none of the statements contained in any
exhibit, report, statement or certificate furnished by or on behalf of the
Company in connection with the Loan Documents, contains any untrue statement of
a material fact or omits any material fact required to be stated therein or
necessary to make the statements made therein, in light of the circumstances
under which they are made, not misleading as of the time when made or delivered.

         5.19 Solvency. After giving effect to the funding of the initial Loans,
the application of proceeds thereof as contemplated by this Agreement and the
payment of all estimated legal, accounting and other fees related hereto, the
Company will be solvent as of and on the Closing Date.

         5.20 Insurance Subsidiaries. All of the Annual Statements or any other
financial or similar statement of the Insurance Subsidiaries provided to the
Agent, or which shall hereafter be provided to the Agent pursuant to the terms
of this Agreement and any other Loan Document, are, in all material respects,
true and complete statements of all of the assets and liabilities and of the
condition and affairs of the said insurer prepared in accordance with SAP.

         5.21 Year 2000. The Company reasonably believes that (a) it and its
Subsidiaries are taking all necessary and appropriate steps to ascertain the
extent of, and to address appropriately, business and financial risks facing the
Company and its Subsidiaries as a result of what is commonly referred to as the
"Year 2000 problem" (i.e., the inability of certain computer applications to
recognize correctly and perform date-sensitive functions involving certain dates
prior to and after December 31, 1999), including risks resulting from the
failure of key vendors and customers of the Company and its Subsidiaries to
successfully address the Year 2000 problem, and (b) its and its Subsidiaries'
material computer

                                      -36-
<PAGE>   42
applications will, on a timely basis, adequately address the Year 2000 problem
in all material respects.


                                   ARTICLE VI

                              AFFIRMATIVE COVENANTS

     So long as any Bank shall have any Commitment hereunder, or any Loan or
other Obligation shall remain unpaid or unsatisfied, unless the Required Banks
waive compliance in writing:

         6.1 Financial Statements. The Company shall deliver to the Agent, in
form and detail satisfactory to the Agent and the Required Banks (it being
agreed that the delivery to the Agent of the Annual Report on Form 10-K and
Quarterly Reports on Form 10-Q for the Company shall satisfy the requirements
for the delivery of financial statements set forth in subparagraphs (a) and (b)
below), with sufficient copies for each Bank:

                (a) as soon as available, but not later than 90 days after the

which report shall state that such consolidated financial statements present
fairly, in all material respects, the financial position for the periods
indicated in conformity with GAAP applied on a basis consistent with prior years
(except for changes in which the Independent Auditor concurs). Such opinion
shall not be qualified or limited because of a restricted or limited examination
by the Independent Auditor of any material portion of the Company's or any
Subsidiary's records and shall be delivered to the Agent pursuant to a reliance
agreement between the Agent and Banks and such Independent Auditor in form and
substance satisfactory to the Agent;

                (b) as soon as available, but not later than 60 days after the

Subsidiaries of a liability, fine or penalty of $10,000,000 or more; or

                (i) Monetary Judgments. One or more non-interlocutory judgments,
non-interlocutory orders, decrees or arbitration awards is entered against the
Company or any Insurance Subsidiary involving in the aggregate a liability (to
the extent not covered by independent third-party insurance as to which the
insurer does not dispute coverage) as to any single or related series of
transactions, incidents or conditions, of $10,000,000 or more, and the same
shall remain unsatisfied, unvacated and unstayed pending appeal for a period of
30 days after the entry thereof; or

                (j) Non-Monetary Judgments. Any non-monetary judgment, order or
decree is entered against the Company or any Subsidiary which does or would
reasonably be expected to have a Material Adverse Effect, and there shall be any
period of 30 consecutive days during which a stay of enforcement of such
judgment or order, by reason of a pending appeal or otherwise, shall not be in
effect; or

                (k) Change of Control.  There occurs any Change of Control; or

                (l) Loss of Licenses. The insurance department of any state in
which any of the Insurance Subsidiaries is licensed or any other Governmental
Authority revokes or fails to renew any material license, permit or franchise of
the Company or any Insurance Subsidiary, or the Company or any Insurance
Subsidiary for any reason loses any material license, permit or franchise, or
the Company or any Insurance Subsidiary suffers the imposition of any
restraining order, escrow, suspension or impound of funds in connection with any
proceeding (judicial or administrative) with respect to any material license,
permit or franchise, and any of the foregoing results or is reasonably likely to
result in a Material Adverse Effect; or

                (m) Adverse Change.  There occurs a Material Adverse Effect; or

                (n) Change in Regulation. Any change is made in the laws or
regulations of the states of organization or domicile of any Insurance
Subsidiary affecting the investment or dividend practices of any Insurance
Subsidiary and which would reasonably be expected to result in a Material
Adverse Effect.

         8.2 Remedies. If any Event of Default occurs, the Agent shall, at the
request of, or may, with the consent of, the Required Banks,

                                      -49-
<PAGE>   55
                (a) declare the commitment of each Bank to make Loans to be
terminated, whereupon such commitments shall be terminated;

                (b) declare the unpaid principal amount of all outstanding
Loans, all interest accrued and unpaid thereon, and all other amounts owing or
payable hereunder or under any other Loan Document to be immediately due and
payable, without presentment, demand, protest or other notice of any kind, all
of which are hereby expressly waived by the Company; and

                (c) exercise on behalf of itself and the Banks all rights and
remedies available to it and the Banks under the Loan Documents or applicable
law;

provided, however, that upon the occurrence of any event specified in subsection
(f) or (g) of Section 8.1 (in the case of clause (i) of subsection (g) upon the
expiration of the 60-day period mentioned therein), the obligation of each Bank
to make Loans shall automatically terminate and the unpaid principal amount of
all outstanding Loans and all interest and other amounts as aforesaid shall
automatically become due and payable without further act of the Agent or any
Bank.

         8.3 Rights Not Exclusive. The rights provided for in this Agreement and
the other Loan Documents are cumulative and are not exclusive of any other
rights, powers, privileges or remedies provided by law or in equity, or under
any other instrument, document or agreement now existing or hereafter arising.


                                   ARTICLE IX

                                    THE AGENT

         9.1 Appointment and Authorization. Each Bank hereby irrevocably
(subject to Section 9.9) appoints, designates and authorizes the Agent to take
such action on its behalf under the provisions of this Agreement and each other
Loan Document and to exercise such powers and perform such duties as are
expressly delegated to it by the terms of this Agreement or any other Loan
Document, together with such powers as are reasonably incidental thereto.
Notwithstanding any provision to the contrary contained elsewhere in this
Agreement or in any other Loan Document, the Agent shall not have any duties or
responsibilities, except those expressly set forth herein, nor shall the Agent
have or be deemed to have any fiduciary relationship with any Bank, and no
implied covenants, functions, responsibilities, duties, obligations or
liabilities shall be read into this Agreement or any other Loan Document or
otherwise exist against the Agent.

                                      -50-
<PAGE>   56
         9.2 Delegation of Duties. The Agent may execute any of its duties under
this Agreement or any other Loan Document by or through agents, employees or
attorneys-in-fact and shall be entitled to advice of counsel concerning all
matters pertaining to such duties. The Agent shall not be responsible for the
negligence or misconduct of any agent or attorney-in-fact that it selects with
reasonable care.

         9.3 Liability of Agent. None of the Agent-Related Persons shall (i) be
liable for any action taken or omitted to be taken by any of them under or in
connection with this Agreement or any other Loan Document or the transactions
contemplated hereby (except for its own gross negligence or willful misconduct),
or (ii) be responsible in any manner to any of the Banks for any recital,
statement, representation or warranty made by the Company or any Subsidiary or
Affiliate of the Company, or any officer thereof, contained in this Agreement or
in any other Loan Document, or in any certificate, report, statement or other
document referred to or provided for in, or received by the Agent under or in
connection with, this Agreement or any other Loan Document, or the validity,
effectiveness, genuineness, enforceability or sufficiency of this Agreement or
any other Loan Document, or for any failure of the Company or any other party to
any Loan Document to perform its obligations hereunder or thereunder. No
Agent-Related Person shall be under any obligation to any Bank to ascertain or
to inquire as to the observance or performance of any of the agreements
contained in, or conditions of, this Agreement or any other Loan Document, or to
inspect the properties, books or records of the Company or any of the Company's
Subsidiaries or Affiliates.

         9.4 Reliance by Agent. The Agent shall be entitled to rely, and shall
be fully protected in relying, upon any writing, resolution, notice, consent,
certificate, affidavit, letter, telegram, facsimile, telex or telephone message,
statement or other document or conversation believed by it to be genuine and
correct and to have been signed, sent or made by the proper Person or Persons,
and upon advice and statements of legal counsel (including counsel to the
Company), independent accountants and other experts selected by the Agent. The
Agent shall be fully justified in failing or refusing to take any action under
this Agreement or any other Loan Document unless it shall first receive such
advice or concurrence of the Required Banks as it deems appropriate and, if it
so requests, it shall first be indemnified to its satisfaction by the Banks
against any and all liability and expense which may be incurred by it by reason
of taking or continuing to take any such action. The Agent shall in all cases be
fully protected in acting, or in refraining from acting, under this Agreement or
any other Loan Document in accordance with a request or consent of the Required
Banks and such request and any action taken or failure to act pursuant thereto
shall be binding upon all of the Banks.

                                      -51-
<PAGE>   57
         9.5 Notice of Default. The Agent shall not be deemed to have knowledge
or notice of the occurrence of any Default or Event of Default, except with
respect to defaults in the payment of principal, interest and fees required to
be paid to the Agent for the account of the Banks, unless the Agent shall have
received written notice from a Bank or the Company referring to this Agreement,
describing such Default or Event of Default and stating that such notice is a
"notice of default". The Agent will notify the Banks of its receipt of any such
notice. The Agent shall take such action with respect to such Default or Event
of Default as may be requested by the Required Banks in accordance with Article
VIII; provided, however, that unless and until the Agent has received any such
request, the Agent may (but shall not be obligated to) take such action, or
refrain from taking such action, with respect to such Default or Event of
Default as it shall deem advisable or in the best interest of the Banks.

         9.6 Credit Decision. Each Bank acknowledges that none of the
Agent-Related Persons has made any representation or warranty to it, and that no
act by the Agent hereinafter taken, including any review of the affairs of the
Company and its Subsidiaries, shall be deemed to constitute any representation
or warranty by any Agent-Related Person to any Bank. Each Bank represents to the
Agent that it has, independently and without reliance upon any Agent-Related
Person and based on such documents and information as it has deemed appropriate,
made its own appraisal of and investigation into the business, prospects,
operations, property, financial and other condition and creditworthiness of the
Company and its Subsidiaries, and all applicable bank regulatory laws relating
to the transactions contemplated hereby, and made its own decision to enter into
this Agreement and to extend credit to the Company hereunder. Each Bank also
represents that it will, independently and without reliance upon any
Agent-Related Person and based on such documents and information as it shall
deem appropriate at the time, continue to make its own credit analysis,
appraisals and decisions in taking or not taking action under this Agreement and
the other Loan Documents, and to make such investigations as it deems necessary
to inform itself as to the business, prospects, operations, property, financial
and other condition and creditworthiness of the Company. Except for notices,
reports and other documents expressly herein required to be furnished to the
Banks by the Agent, the Agent shall not have any duty or responsibility to
provide any Bank with any credit or other information concerning the business,
prospects, operations, property, financial and other condition or
creditworthiness of the Company which may come into the possession of any of the
Agent-Related Persons.

         9.7 Indemnification. Whether or not the transactions contemplated
hereby are consummated, the Banks shall indemnify upon demand the Agent-Related
Persons (to the extent not reimbursed by

                                      -52-
<PAGE>   58
or on behalf of the Company and without limiting the obligation of the Company
to do so), pro rata, from and against any and all Indemnified Liabilities;
provided, however, that no Bank shall be liable for the payment to the
Agent-Related Persons of any portion of such Indemnified Liabilities resulting
solely from such Person's gross negligence or willful misconduct. Without
limitation of the foregoing, each Bank shall reimburse the Agent upon demand for
its ratable share of any costs or out-of-pocket expenses (including Attorney
Costs) incurred by the Agent in connection with the preparation, execution,
delivery, administration, modification, amendment or enforcement (whether
through negotiations, legal proceedings or otherwise) of, or legal advice in
respect of rights or responsibilities under, this Agreement, any other Loan
Document, or any document contemplated by or referred to herein, to the extent
that the Agent is not reimbursed for such expenses by or on behalf of the
Company. The undertaking in this Section shall survive the payment of all
Obligations hereunder and the resignation or replacement of the Agent.

         9.8 Agent in Individual Capacity. BofA and its Affiliates may make
loans to, issue letters of credit for the account of, accept deposits from,
acquire equity interests in and generally engage in any kind of banking, trust,
financial advisory, underwriting or other business with the Company and its
Subsidiaries and Affiliates as though BofA were not the Agent hereunder and
without notice to or consent of the Banks. The Banks acknowledge that, pursuant
to such activities, BofA or its Affiliates may receive information regarding the
Company or its Affiliates (including information that may be subject to
confidentiality obligations in favor of the Company or such Subsidiary) and
acknowledge that the Agent shall be under no obligation to provide such
information to them. With respect to its Loans, BofA shall have the same rights
and powers under this Agreement as any other Bank and may exercise the same as
though it were not the Agent, and the terms "Bank" and "Banks" include BofA in
its individual capacity.

         9.9 Successor Agent. The Agent may, and at the request of the Required
Banks shall, resign as Agent upon 30 days' notice to the Banks. If the Agent
resigns under this Agreement, the Required Banks shall appoint from among the
Banks a successor agent for the Banks which successor agent shall be approved by
the Company. If no successor agent is appointed prior to the effective date of
the resignation of the Agent, the Agent may appoint, after consulting with the
Banks and the Company, a successor agent from among the Banks. Upon the
acceptance of its appointment as successor agent hereunder, such successor agent
shall succeed to all the rights, powers and duties of the retiring Agent and the
term "Agent" shall mean such successor agent and the retiring Agent's
appointment, powers and duties as Agent shall be terminated. After any retiring
Agent's resignation hereunder as Agent, the provisions of this

                                      -53-
<PAGE>   59
Article IX and Sections 10.4 and 10.5 shall inure to its benefit as to any
actions taken or omitted to be taken by it while it was Agent under this
Agreement. If no successor agent has accepted appointment as Agent by the date
which is 30 days following a retiring Agent's notice of resignation, the
retiring Agent's resignation shall nevertheless thereupon become effective and
the Banks shall perform all of the duties of the Agent hereunder until such
time, if any, as the Required Banks appoint a successor agent as provided for
above.

         9.10 Withholding Tax. (a) If any Bank is a "foreign corporation,
partnership or trust" within the meaning of the Code and such Bank claims
exemption from, or a reduction of, U.S. withholding tax under Sections 1441 or
1442 of the Code, such Bank agrees with and in favor of the Agent, to deliver to
the Agent:

                             (i) if such Bank claims an exemption from, or a
         reduction of, withholding tax under a United States tax treaty,
         properly completed IRS Forms 1001 and W-8 before the payment of any
         interest in the first calendar year and before the payment of any
         interest in each third succeeding calendar year during which interest
         may be paid under this Agreement;

                             (ii) if such Bank claims that interest paid under
         this Agreement is exempt from United States withholding tax because it
         is effectively connected with a United States trade or business of such
         Bank, two properly completed and executed copies of IRS Form 4224
         before the payment of any interest is due in the first taxable year of
         such Bank and in each succeeding taxable year of such Bank during which
         interest may be paid under this Agreement, and IRS Form W-9; and

                              (iii) such other form or forms as may be required
         under the Code or other laws of the United States as a condition to
         exemption from, or reduction of, United States withholding tax.

Such Bank agrees to promptly notify the Agent of any change in circumstances
which would modify or render invalid any claimed exemption or reduction.

                (b) If any Bank claims exemption from, or reduction of,
withholding tax under a United States tax treaty by providing IRS Form 1001 and
such Bank sells, assigns, grants a participation in, or otherwise transfers all
or part of the Obligations of the Company to such Bank, such Bank agrees to
notify the Agent of the percentage amount in which it is no longer the
beneficial owner of Obligations of the Company to such Bank. To the extent of
such percentage amount, the Agent will treat such Bank's IRS Form 1001 as no
longer valid.

                                      -54-
<PAGE>   60
                (c) If any Bank claiming exemption from United States
withholding tax by filing IRS Form 4224 with the Agent sells, assigns, grants a
participation in, or otherwise transfers all or part of the Obligations of the
Company to such Bank, such Bank agrees to undertake sole responsibility for
complying with the withholding tax requirements imposed by Sections 1441 and
1442 of the Code.

                (d) If any Bank is entitled to a reduction in the applicable
withholding tax, the Agent may withhold from any interest payment to such Bank
an amount equivalent to the applicable withholding tax after taking into account
such reduction. If the forms or other documentation required by subsection (a)
of this Section are not delivered to the Agent, then the Agent may withhold from
any interest payment to such Bank not providing such forms or other
documentation an amount equivalent to the applicable withholding tax.

                (e) If the IRS or any other Governmental Authority of the United
States or other jurisdiction asserts a claim that the Agent did not properly
withhold tax from amounts paid to or for the account of any Bank (because the
appropriate form was not delivered, was not properly executed, or because such
Bank failed to notify the Agent of a change in circumstances which rendered the
exemption from, or reduction of, withholding tax ineffective, or for any other
reason) such Bank shall indemnify the Agent fully for all amounts paid, directly
or indirectly, by the Agent as tax or otherwise, including penalties and
interest, and including any taxes imposed by any jurisdiction on the amounts
payable to the Agent under this Section, together with all costs and expenses
(including Attorney Costs). The obligation of the Banks under this subsection
shall survive the payment of all Obligations and the resignation or replacement
of the Agent.

                                  MISCELLANEOUS

         10.1 Amendments and Waivers. No amendment or waiver of any provision of
this Agreement or any other Loan Document, and no consent with respect to any
departure by the Company therefrom, shall be effective unless the same shall be
in writing and signed by the Required Banks (or by the Agent at the written
request of the Required Banks) and the Company and acknowledged by the Agent,
and then any such waiver or consent shall be effective only in the specific
instance and for the specific purpose for which given; provided, however, that
no such waiver, amendment, or consent shall, unless in writing and signed by all
the Banks and the Company and acknowledged by the Agent, do any of the
following:

any Commitment terminated pursuant to Section 8.2);

                (b) postpone or delay any date fixed by this Agreement or any
other Loan Document for any payment of principal, interest, fees or other
amounts due to the Banks (or any of them) hereunder or under any other Loan
Document;

                (c) reduce the principal of, or the rate of interest specified
herein on any Loan, or (subject to clause (ii) below) any fees or other amounts
payable hereunder or under any other Loan Document;

                (d) change the percentage of the Commitments or of the aggregate

                (e) amend this Section, or Section 2.14, or any provision herein
providing for consent or other action by all Banks;

and, provided further, that (i) no amendment, waiver or consent shall, unless in
writing and signed by the Agent in addition to the Required Banks or all the
Banks, as the case may be, affect the rights or duties of the Agent under this
Agreement or any other Loan Document, and (ii) the Fee Letter may be amended, or
rights or privileges thereunder waived, in a writing executed by the parties
thereto.

         10.2 Notices. (a) All notices, requests and other communications shall
be in writing (including, unless the context expressly otherwise provides, by
facsimile transmission, provided that any matter transmitted by the Company by
facsimile (i) shall be immediately confirmed by a telephone call to the
recipient at the number specified on Schedule 10.2, and (ii) shall be followed
promptly by delivery of a hard copy original thereof) and mailed, faxed or
delivered, to the address or facsimile number specified for notices on Schedule
10.2; or, as directed to the Company or the Agent, to such other address as

<PAGE>   62
         (c) Any agreement of the Agent and the Banks herein to receive certain
notices by telephone or facsimile is solely for the convenience and at the
request of the Company. The Agent and the Banks shall be entitled to rely on the
authority of any Person purporting to be a Person authorized by the Company to
give such notice and the Agent and the Banks shall not have any liability to the
Company or other Person on account of any action taken or not taken by the Agent
or the Banks in reliance upon such telephonic or facsimile notice. The
obligation of the Company to repay the Loans shall not be affected in any way or
to any extent by any failure by the Agent and the Banks to receive written
confirmation of any telephonic or facsimile notice or the receipt by the Agent
and the Banks of a confirmation which is at variance with the terms understood
by the Agent and the Banks to be contained in the telephonic or facsimile
notice.

         10.3 No Waiver; Cumulative Remedies. No failure to exercise and no
delay in exercising, on the part of the Agent or any Bank, any right, remedy,
power or privilege hereunder, shall operate as a waiver thereof; nor shall any
single or partial exercise of any right, remedy, power or privilege hereunder
preclude any other or further exercise thereof or the exercise of any other
right, remedy, power or privilege.

         10.4 Costs and Expenses.  The Company shall:

                (a) whether or not the transactions contemplated hereby are
consummated, pay or reimburse BofA (including in its capacity as Agent) within
five Business Days after demand (subject to subsection 4.1(e)) for all costs and
expenses incurred by BofA (including in its capacity as Agent) in connection
with the development, preparation, delivery, administration and execution of,
and any amendment, supplement, waiver or modification to (in each case, whether
or not consummated), this Agreement, any Loan Document and any other documents
prepared in connection herewith or therewith, and the consummation of the
transactions contemplated hereby and thereby, including reasonable Attorney
Costs incurred by BofA (including in its capacity as Agent) with respect
thereto; and

                (b) pay or reimburse the Agent, the Arranger and each Bank
within five Business Days after demand (subject to subsection 4.1(e)) for all
costs and expenses (including Attorney Costs) incurred by them in connection
with the enforcement, attempted enforcement, or preservation of any rights or
remedies under this Agreement or any other Loan Document during the existence of
an Event of Default or after acceleration of the Loans (including in connection
with any "workout" or restructuring regarding the Loans, and including in any
Insolvency Proceeding or appellate proceeding).

                                      -57-
<PAGE>   63
         10.5 Indemnity. Whether or not the transactions contemplated hereby are
consummated, the Company shall indemnify and hold the Agent-Related Persons, and
each Bank and each of its respective officers, directors, employees, counsel,
agents and attorneys-in-fact (each, an "Indemnified Person") harmless from and
against any and all liabilities, obligations, losses, damages, penalties,
actions, judgments, suits, costs, charges, expenses and disbursements (including
Attorney Costs) of any kind or nature whatsoever which may at any time
(including at any time following repayment of the Loans and the termination,
resignation or replacement of the Agent or replacement of any Bank) be imposed
on, incurred by or asserted against any such Person in any way relating to or
arising out of this Agreement or any document contemplated by or referred to
herein, or the transactions contemplated hereby, or any action taken or omitted
by any such Person under or in connection with any of the foregoing, including
with respect to any investigation, litigation or proceeding (including any
Insolvency Proceeding or appellate proceeding) related to or arising out of this
Agreement or the Loans or the use of the proceeds thereof, whether or not any
Indemnified Person is a party thereto (all the foregoing, collectively, the
"Indemnified Liabilities"); provided, that the Company shall have no obligation
hereunder to any Indemnified Person with respect to Indemnified Liabilities
resulting solely from the gross negligence or willful misconduct of such
Indemnified Person or to any Bank on account of interest required to be paid by
such Bank to the Agent pursuant to Section 2.12. The agreements in this Section
shall survive payment of all other Obligations.

         10.6 Payments Set Aside. To the extent that the Company makes a payment
to the Agent or the Banks, or the Agent or the Banks exercise their right of
set-off, and such payment or the proceeds of such set-off or any part thereof
are subsequently invalidated, declared to be fraudulent or preferential, set
aside or required (including pursuant to any settlement entered into by the
Agent or such Bank in its discretion) to be repaid to a trustee, receiver or any
other party, in connection with any Insolvency Proceeding or otherwise, then (a)
to the extent of such recovery the obligation or part thereof originally
intended to be satisfied shall be revived and continued in full force and effect
as if such payment had not been made or such set-off had not occurred, and (b)
each Bank severally agrees to pay to the Agent upon demand its pro rata share of
any amount so recovered from or repaid by the Agent.

         10.7 Successors and Assigns. The provisions of this Agreement shall be
binding upon and inure to the benefit of the parties hereto and their respective
successors and assigns, except that the Company may not assign or transfer any
of its rights or obligations under this Agreement without the prior written
consent of the Agent and each Bank.

<PAGE>   64
         10.8 Assignments, Participations, etc. (a) Any Bank may, with the
written consent of the Company at all times other than during the existence of
an Event of Default and the Agent, which consents shall not be unreasonably
withheld, at any time assign and delegate to one or more Eligible Assignees
(provided that no written consent of the Company or the Agent shall be required
in connection with any assignment and delegation by a Bank to an Eligible
Assignee that is an Affiliate of such Bank) (each an "Assignee") all, or any
ratable part of all, of the Loans, the Commitments and the other rights and
obligations of such Bank hereunder, in a minimum amount of $10,000,000;
provided, however, that the Company and the Agent may continue to deal solely
and directly with such Bank in connection with the interest so assigned to an
Assignee until (i) written notice of such assignment, together with payment
instructions, addresses and related information with respect to the Assignee,
shall have been given to the Company and the Agent by such Bank and the
Assignee; (ii) such Bank and its Assignee shall have delivered to the Company
and the Agent an Assignment and Acceptance in the form of Exhibit E ("Assignment
and Acceptance") together with any Note or Notes subject to such assignment and
(iii) the assignor Bank has paid to the Agent a processing fee in the amount of
$3,500.

                (b) From and after the date that the Agent notifies the assignor
Bank that it has received (and provided its consent with respect to) an executed
Assignment and Acceptance and payment of the above-referenced processing fee,
and provided that the consent of the Company, if required pursuant to subsection
10.8(a), shall have been obtained, (i) the Assignee thereunder shall be a party
hereto and, to the extent that rights and obligations hereunder have been
assigned to it pursuant to such Assignment and Acceptance, shall have the rights
and obligations of a Bank under the Loan Documents, and (ii) the assignor Bank
shall, to the extent that rights and obligations hereunder and under the other
Loan Documents have been assigned by it pursuant to such Assignment and
Acceptance, relinquish its rights and be released from its obligations under the
Loan Documents.

                (c) Within five Business Days after its receipt of notice by the
Agent that it has received an executed Assignment and Acceptance and payment of
the processing fee, (and provided that it consents to such assignment in
accordance with subsection 10.8(a), the Company shall execute and deliver to the
Agent, new Notes evidencing such Assignee's assigned Loans and Commitment and,
if the assignor Bank has retained a portion of its Loans and its Commitment,
replacement Notes in the principal amount of the Loans retained by the assignor
Bank (such Notes to be in exchange for, but not in payment of, the Notes held by
such Bank). Immediately upon each Assignee's making its processing fee payment
under the Assignment and Acceptance, this Agreement shall be deemed to be
amended to the extent, but only to the extent, necessary to reflect

                                      -59-
<PAGE>   65
the addition of the Assignee and the resulting adjustment of the Commitments
arising therefrom. The Commitment allocated to each Assignee shall reduce such
Commitments of the assigning Bank pro tanto.

                (d) Any Bank may at any time sell to one or more commercial
banks or other Persons not Affiliates of the Company (a "Participant")
participating interests in any Loans, the Commitment of that Bank and the other
interests of that Bank (the "originating Bank") hereunder and under the other
Loan Documents; provided, however, that (i) the originating Bank's obligations
under this Agreement shall remain unchanged, (ii) the originating Bank shall
remain solely responsible for the performance of such obligations, (iii) the
Company and the Agent shall continue to deal solely and directly with the
originating Bank in connection with the originating Bank's rights and
obligations under this Agreement and the other Loan Documents, and (iv) no Bank
shall transfer or grant any participating interest under which the Participant
has rights to approve any amendment to, or any consent or waiver with respect
to, this Agreement or any other Loan Document, except to the extent such
amendment, consent or waiver would require unanimous consent of the Banks as
described in the first proviso to Section 10.1. In the case of any such
participation, the Participant shall be entitled to the benefit of Sections 3.1,
3.3 and 10.5 as though it were also a Bank hereunder, and not have any rights
under this Agreement, or any of the other Loan Documents, and all amounts
payable by the Company hereunder shall be determined as if such Bank had not
sold such participation; except that, if amounts outstanding under this
Agreement are due and unpaid, or shall have been declared or shall have become
due and payable upon the occurrence of an Event of Default, each Participant
shall be deemed to have the right of set-off in respect of its participating
interest in amounts owing under this Agreement to the same extent as if the
amount of its participating interest were owing directly to it as a Bank under
this Agreement.

                (e) Notwithstanding any other provision in this Agreement, any
Bank may at any time create a security interest in, or pledge, all or any
portion of its rights under and interest in this Agreement and the Note held by
it in favor of any Federal Reserve Bank in accordance with Regulation A of the
FRB or U.S. Treasury Regulation 31 CAR Section203.14, and such Federal Reserve
Bank may enforce such pledge or security interest in any manner permitted under
applicable law.

         10.9 Confidentiality. Each Bank agrees to take and to cause its
Affiliates to take normal and reasonable precautions and exercise due care to
maintain the confidentiality of all information identified as "confidential" or
"secret" by the Company and provided to it by the Company or any Subsidiary, or
by the Agent on such Company's or Subsidiary's behalf, under this

                                      -60-
<PAGE>   66
Agreement or any other Loan Document, and neither it nor any of its Affiliates
shall use any such information other than in connection with or in enforcement
of this Agreement and the other Loan Documents or in connection with other
business now or hereafter existing or contemplated with the Company or any
Subsidiary; except to the extent such information (i) was or becomes generally
available to the public other than as a result of disclosure by the Bank, or
(ii) was or becomes available on a non-confidential basis from a source other
than the Company, provided that such source is not bound by a confidentiality
agreement with the Company known to the Bank; provided, however, that any Bank
may disclose such information (A) at the request or pursuant to any requirement
of any Governmental Authority to which the Bank is subject or in connection with
an examination of such Bank by any such authority; (B) pursuant to subpoena or
other court process; (C) when required to do so in accordance with the
provisions of any applicable Requirement of Law; (D) to the extent reasonably
required in connection with any litigation or proceeding to which the Agent, any
Bank or their respective Affiliates may be party; (E) to the extent reasonably
required in connection with the exercise of any remedy hereunder or under any
other Loan Document; (F) to such Bank's independent auditors and other
professional advisors; (G) to any Participant or Assignee, actual or potential,

confidential to the same extent required of the Banks hereunder; (H) as to any
Bank or its Affiliate, as expressly permitted under the terms of any other
document or agreement regarding confidentiality to which the Company or any
Subsidiary is party or is deemed party with such Bank or such Affiliate; and (I)
to its Affiliates.

         10.10 Set-off. In addition to any rights and remedies of the Banks
provided by law, if an Event of Default exists or the Loans have been
accelerated, each Bank is authorized at any time and from time to time, without
prior notice to the Company, any such notice being waived by the Company to the
fullest extent permitted by law, to set off and apply any and all deposits
(general or special, time or demand, provisional or final) at any time held by,
and other indebtedness at any time owing by, such Bank to or for the credit or
the account of the Company against any and all Obligations owing to such Bank,
now or hereafter existing, irrespective of whether or not the Agent or such Bank
shall have made demand under this Agreement or any Loan Document and although
such Obligations may be contingent or unmatured. Each Bank agrees promptly to
notify the Company and the Agent after any such set-off and application made by
such Bank; provided, however, that the failure to give such notice shall not
affect the validity of such set-off and application.

         10.11  Notification of Addresses, Lending Offices, Etc.  Each Bank
shall notify the Agent in writing of any changes in the address to which notices
to the Bank should be directed, of

                                      -61-

payments to be made to it hereunder and of such other administrative information
as the Agent shall reasonably request.

separate counterparts, each of which, when so executed, shall be deemed an
original, and all of said counterparts taken together shall be deemed to
constitute but one and the same instrument.

         10.13 Severability. The illegality or unenforceability of any provision
of this Agreement or any instrument or agreement required hereunder shall not in
any way affect or impair the legality or enforceability of the remaining
provisions of this Agreement or any instrument or agreement required hereunder.

         10.14 No Third Parties Benefited. This Agreement is made and entered
into for the sole protection and legal benefit of the Company, the Banks, the
Agent and the Agent-Related Persons, and their permitted successors and assigns,
and no other Person shall be a direct or indirect legal beneficiary of, or have
any direct or indirect cause of action or claim in connection with, this
Agreement or any of the other Loan Documents.

         10.15 Governing Law and Jurisdiction. (a) THIS AGREEMENT AND THE NOTES
SHALL BE GOVERNED BY, AND CONSTRUED IN ACCORDANCE WITH, THE LAW OF THE STATE OF
ILLINOIS; PROVIDED THAT THE AGENT AND THE BANKS SHALL RETAIN ALL RIGHTS ARISING
UNDER FEDERAL LAW.

                (b) ANY LEGAL ACTION OR PROCEEDING WITH RESPECT TO THIS

Bank of America, National Association,
   as Administrative Agent
231 South LaSalle Street
Chicago, Illinois 60697


Ladies and Gentlemen:

         We have acted as counsel to W.R. Berkley Corporation ("Company") in
connection with the preparation, execution and delivery of the Credit Agreement,
dated as of December 10, 1999 (the "Credit Agreement") (together with the
documents referred to therein, the "Loan Documents"), among the Company, certain
banks and Bank of America, National Association, as administrative agent. This
opinion is rendered to you pursuant to Section 4.1(d) of the Credit Agreement.
Capitalized terms used herein and not otherwise defined herein shall have the
respective meanings ascribed to them in the Credit Agreement.

         In so acting, we have examined originals or copies, certified or
otherwise identified to our satisfaction, of such documents as we have deemed
necessary or appropriate as a basis for the opinions hereinafter set forth. In
examining such documents, we have assumed the genuineness of the signatures of
all parties, the authenticity of all documents purporting to be originals and
the conformity to originals of all documents purporting to be copied.

         As to various questions of fact material to such opinions, we have
relied upon certificates of responsible officers of the Company and public
officials.

         Based upon the foregoing, and subject to the qualifications set forth
below, we are of the opinion that:

         1. The Company is a corporation duly organized, validly existing and in
good standing under the laws of the State of Delaware.

         2. The Company is duly qualified as a foreign corporation to do or
transact business in, and is in good standing under the laws of, each
jurisdiction in which the ownership or lease of its property or the conduct of
its business requires such qualification, except for jurisdictions in which
failure by it so to qualify would not have a Material Adverse Effect.

         3.       The Company has the requisite corporate power and
authority and all governmental licenses, authorizations,

                                      -74-
<PAGE>   80
consents, certificates of authority and approvals to own or lease its assets or
properties and to conduct its business as currently conducted. The Company has
the requisite corporate power and authority to execute, deliver and enter into,
and to incur and perform its obligations under, the Loan Documents.

         4. The execution, delivery and performance by the Company of its
obligations under the Loan Documents: (a) have been duly and validly authorized
by all necessary corporate action; (b) do not violate, conflict with or result
in a violation or breach of, accelerate any performance required by the Company
under, or create or impose any Lien on, any of the Company's properties or
assess (except as may be provided in and pursuant to the Loan Documents) by
reason of the terms of (i) the Certificate of Incorporation or by laws of the
Company, (ii) any law, rule or regulation of any Governmental Authority
applicable to the Company or by or to which the Company or its properties are
bound or subject; or (iii) to our knowledge, any order, writ, judgment,
injunction or decree of any court or other Governmental Authority, or, to our
knowledge, any indenture, mortgage, deed of trust, lease, security agreement or
any other instrument or agreement to which the Company is a party or subject or
by which the Company or its properties are bound; and (c) do not require any
consent or approval of, or registration or filing with, any court, Governmental
Authority or other Person which has not been obtained or filed as of the date
hereof.

         5. The Loan Documents have been duly executed and delivered by the
Company and constitute the legal, valid and binding obligations of the Company,
enforceable against the Company in accordance with their terms, subject only to
(i) bankruptcy, insolvency, reorganization, moratorium, arrangement or similar
laws relating to or affecting the rights of creditors generally and (ii) general
principles of equity with respect to availability of equitable remedies,
regardless of whether enforcement is sought in proceedings at law or in equity.

         6. To our knowledge, there are no actions, suits, investigations or
proceedings (whether or not purportedly on behalf of the Company) pending or
threatened against the Company before or by any governmental agency, or court,
arbitrator or grand jury that, if adversely determined, could reasonably be
expected to have a Material Adverse Effect. To our knowledge, the Company is not
in default with respect to any judgment, order, writ, injunction, decree,
demand, rule or regulation of any court, arbitrator, grand jury, or of any
governmental agency, which default could reasonably be expected to have a
Material Adverse Effect.

         We are members only of the Bar of the Sate of New York and do not
purport to be experts in the laws of jurisdictions other than the State of New
York, except for The General Corporation Law of the State of Delaware and
federal laws of the United States of America, and the opinions set forth herein
are accordingly limited to said laws of those jurisdictions. To the

                                      -75-
<PAGE>   81
extent the opinions expressed herein involve the laws of the State of Illinois,
we have assumed that the laws of the State of Illinois are the same as those of
the State of New York.

         The opinions hereinbefore expressed are limited by principles of equity
which may limit the availability of certain rights and remedies, and do not
reflect the effect of bankruptcy, insolvency, reorganization, moratorium and
other laws applicable to creditors' rights and debtors' obligations generally.

         This opinion is being provided to the Banks in connection with the
transactions contemplated by the Loan Documents and may not be relied upon by
the Banks for any other purpose and may not be relied upon by any other person,
firm, corporation or entity, except for successors to the Banks and Assignees
and Participants.

                                                     Very truly yours,

                                      -76-

January 24, 2000


John D. Vollaro
26 Old Orchard Hill Lane
Greenwich, Connecticut  06831

Dear John:

In recognition of your many years of service and highly valued contributions, I
am pleased to set forth our mutual agreement regarding your resignation as
President and Chief Operating Officer of W.R. Berkley Corporation (the
"Company").

1.        Your resignation from the Company as President and Chief Operating
          Officer will be effective as of the close of business on March 1,
          2000.

2.        You will continue to have the use of your current office and
          secretarial arrangements through March 1, 2000. Thereafter, at your
          request, the Company will provide a temporary office for your use
          until the earlier of one year from the date hereof or the date on
          which you commence other employment.

3.        The Company will pay you annual compensation at the rate of $620,000
          per year for the period commencing on March 1, 2000 and terminating on
          February 28, 2001 and at the rate of $650,000 per year for the period
          commencing on March 1, 2001 and terminating on February 28, 2003. Such
          payments will be made on a biweekly basis on the Company's regular
          payroll cycle.

4.       The Company will make additional payments to you of $300,000 on January
         1, 2001 and $300,000 on January 1, 2002; provided, however, that you
         will not be entitled to the payment of $300,000 on January 1, 2002 (the
         "Second Installment Payment") if, prior to such date, you have
         commenced other employment, whether or not you continue to be employed
         on January 1, 2002. For purposes of this letter agreement, "other
         employment" shall include any services as an employee, independent
         contractor, consultant or advisor other than Limited Consulting
         Services. Limited Consulting Services means services provided by you to
         any one or more unrelated

Page 2


         employers or businesses (other than the Company) prior to or as of
         January 1, 2002 which (i) consist solely of consultation and advice
         directed to specific aspects of the business or affairs of such
         employer or business (each, with its affiliates, an "Employer") and not
         to the business or affairs of the Employer, or of an operating unit or
         segment thereof, as a whole; (ii) do not extend, for any Employer, for
         a period of more than 120 days, whether or not consecutive; (iii) do
         not involve or result in your employment by an Employer, or the
         provision by you of consulting or advisory services (other than Limited
         Consulting Services) to such Employer, or your becoming an officer or
         director of such Employer, in each such case at any time prior to March
         1, 2003; (iv) do not involve or result in an agreement or arrangement
         (whether or not in writing), at any time prior to March 1, 2003, for
         your employment by, or your provision of consulting or advisory
         services to, or your becoming an officer or director of, an Employer;
         (v) do not result in your being eligible for benefits from the Employer
         of a kind referred to in the second sentence of paragraph 8 hereof; and
         (vi) do not preclude you from performing your obligations under
         paragraph 7 hereof. You will, prior to performing Limited Consulting
         Services for any Employer, advise the Company in writing of the name of
         such Employer (except that you need not advise the Company of the name
         of an Employer that does not engage in any business that is competitive
         with any business of the Company) and the nature and principal terms of
         such Limited Consulting Services and shall certify in writing that such
         services will constitute Limited Consulting Services hereunder. In the
         event that the Chairman of the Board of the Company believes that any
         services so to be provided by you should not be deemed to be Limited
         Consulting Services, such matter shall be referred for resolution to
         Jack H. Nusbaum, whose determination with respect thereto shall be
         final and binding upon you and the Company, and each of you and the
         Company agrees not to challenge such determination in any action or
         proceeding. In the event of a breach by you of any of the provisions of
         this paragraph 4, or if you should receive any payment or benefits
         under this letter agreement to which you are not entitled because you
         commenced other employment, and without limiting any other rights or
         remedies available to the Company with respect to such breach, the
         Company shall be entitled to (i) recover the Second Installment
         Payment, if already made, together with the costs of any such benefits,
         and/or (ii) without duplication of any recovery under clause (i), cease
         making payments under this letter agreement provided that the amount of
         payments ceased being made shall

<PAGE>   3

         not exceed the amount of the Second Installment Payment plus the amount
         of any such costs.

5.        Options to purchase shares of the Company's common stock granted to
          you under the W.R. Berkley Corporation First Amended and Restated 1992
          Stock Option Plan which shall have vested as of the earlier of the
          dates hereinafter referred to shall be canceled and of no force or
          effect from and after the earlier of March 1, 2003 or the date on
          which you commence other employment, and, except as otherwise provided
          herein, prior to such cancellation shall continue to be subject to the
          terms and conditions of the option agreements between you and the
          Company pursuant to which such options were granted. You will not be
          granted any options after the date of this letter agreement.

6.        Your active responsibilities as an officer of the Company will
          terminate immediately and your regular employment with the Company
          will terminate effective as of the close of business on March 1, 2000.
          To the extent otherwise eligible, you will continue to participate in
          all Company benefit plans through that date.

7.       The Company will distribute your accumulated benefits under the
         Company's Profit Sharing Plan, Deferred Compensation Plan and Benefit
         Replacement Plan in accordance with each Plan's provisions and, to the
         extent consistent therewith, per your written direction. Anything
         herein to the contrary notwithstanding, to the extent that a
         distribution of your accumulated benefits under the terms any of the
         foregoing plans is conditioned on your termination of employment with
         the Company, you will not be allowed to receive a distribution from
         such plan until your employment has terminated as provided in paragraph
         8 hereof. You acknowledge and agree that you will not be entitled to
         any distribution of benefits accrued as of the date of this letter
         agreement under the Company's Annual Incentive Compensation Plan and
         hereby waive any right to any such benefits. You further acknowledge
         and agree that all outstanding Units (as therein defined) awarded to
         you under the Company's Long-Term Incentive Compensation Plan shall be
         canceled and all of your rights with respect thereto and under such
         plan shall expire upon the date of this letter agreement.

8.       From March 1, 2000 until the earlier of March 1, 2003 or the date on
         which you commence other employment, you will have the status of
         standby employee but you hereby waive any right you have to participate
         during such period in the Company's Profit

         Sharing Plan, Deferred Compensation Plan, Benefit Replacement Plan,
         Annual Incentive Compensation Plan and Long-Term Incentive Compensation
         Plan, and in all of the Company's other executive compensation or
         benefit plans, other than the Company's Flexible Compensation Plan, in
         which you will have the right to continue to participate during such
         period. During such period, the Company will provide you with continued
         medical, term life insurance and long-term disability benefits
         equivalent to that (and at the same cost basis to you) provided for
         other employees or will reimburse you for the cost of comparable
         coverage. Thereafter, you will be able to elect continuation coverage

         Release be held invalid or illegal, such illegality shall not

         of the parties shall be construed and enforced accordingly. If any of
         the restrictions contained herein shall be deemed to be unenforceable
         by reason of the extent, duration or geographical scope thereof, or
         otherwise, then the court making such determination shall have the
         right to reduce such extent, duration, geographical scope or other
         provisions hereof, and in its reduced form this letter agreement shall
         then be enforceable in the manner contemplated hereby.

          obligations. The Company makes no representation regarding the
          taxation of any payments or benefits to be provided to you under, or
          the tax ramifications of any of the matters contemplated by, this
          letter agreement. It is your obligation and responsibility to
          determine whether any such payment or benefit is includible in gross
          income for Federal, state and local income tax purposes.

MANAGEMENT'S DISCUSSION AND ANALYSIS OF
FINANCIAL CONDITION AND RESULTS OF OPERATIONS


INDUSTRY OVERVIEW

The demand for insurance is influenced primarily by general economic conditions,
while the supply of insurance is directly related to available capacity, i.e.,
the level of policyholders' surplus employed in the industry and the willingness
of insurance management to risk that capital. The adequacy of premium rates is
affected mainly by the severity and frequency of claims, which are influenced by
many factors, including natural disasters, regulatory measures and court
decisions that define and expand the extent of coverage and the effects of
economic inflation on the amount of compensation due for injuries or losses. In
addition, investment rates of return may impact policy rates. These factors can
have a significant impact on ultimate profitability because a property casualty
insurance policy is priced before its costs are known, as premiums usually are
determined long before claims are reported. Over the past several years a
significant increase in capacity has produced a trend of increasing price
competition, which continued in 1999.

OPERATING RESULTS FOR THE YEAR ENDED
DECEMBER 31, 1999 AS COMPARED TO THE YEAR
ENDED DECEMBER 31, 1998

The net loss attributable to common stockholders for 1999 was $37 million, or
$1.43 per diluted share, compared to net income of $46 million, or $1.59 per
diluted share, in 1998. The operating loss, which is defined as net loss before
realized gains and losses, changes in accounting principle and extraordinary
gains and losses on early extinguishments of long-term debt, was $31 million in
1999, or $1.19 per diluted share, compared with operating income of $35 million,
or $1.19 per diluted share, in 1998. Adjusting for the restructuring charge (see
page 19), the operating loss was $23 million, or $.91 per diluted share, in
1999. The deterioration in operating results in 1999 was primarily due to an
increase in loss reserves and to the effects of competition on rate adequacy.

Net premiums written increased 6% to $1,428 million from $1,346 million written
during 1998. Regional net premiums written grew 1% to $650 million as growth
opportunities were impeded by inadequate rates and competitive market
conditions. Reinsurance net premiums written increased 15% to $309 million due
primarily to growth in pro-rata treaty business. Specialty net premiums written
were $260 million, an increase of 3% over 1998, as new business growth was
partially offset by the non-renewal of loss-producing business, primarily in the
commercial transportation unit. Alternative markets net premiums written
increased 15% to $122 million due primarily to growth in businesses that began
operations in 1998. International net premiums written increased 15% to $86
million, reflecting the first full year of operations in the Philippines.

Net investment income decreased 6% to $190 million in 1999 due to a reduction in
invested assets, which resulted from the repurchase of common and preferred
shares during 1998 and 1999, and to a lower average pre-tax return on
investments. (See "Liquidity and Capital Resources.") The portfolio yield
decreased to approximately 6.5% in 1999 from approximately 6.9% in 1998 as a
result of a higher concentration in municipal bonds on average during 1999 and a
lower yield on the trading portfolio.

Management fees and commissions consist primarily of fees earned by the
alternative markets segment. Management fees and commissions increased 2% to $72
million in 1999 as market conditions continued to restrain the growth of the
alternative risk market.

Realized investment losses were $6 million in 1999 compared to realized
investment gains of $25 million in 1998. Realized gains and losses on fixed
income securities resulted primarily from the Company's strategy of maintaining
an appropriate balance between the duration of its fixed income portfolio and
the duration of its liabilities and from provisions for other than temporary
impairment of securities; realized gains and losses on equity securities arise
primarily as a result of a vari-


18
<PAGE>   2

ety of factors which influence the Company's valuation criteria for such
securities. The majority of the 1999 and 1998 realized gains and losses resulted
from fixed maturity securities.

The combined ratio represents a measure of underwriting profitability, excluding
investment income. A number in excess of 100 generally indicates an underwriting
loss; a number below 100 generally indicates an underwriting gain. The
consolidated combined ratio (on a statutory basis) of the Company's insurance
operations increased to 112.2% in 1999 from 106.6% in 1998 mainly due to an
increase in the consolidated loss ratio. The consolidated loss ratio (losses and
loss expenses incurred expressed as a percentage of premiums earned) increased
to 76.5% from 71.2% primarily as a result of increased losses in the regional
segment and commercial transportation unit. The regional segment loss ratio
increased to 84.7% from 76.0% in 1998 due to a loss reserve adjustment of $55
million in the fourth quarter of 1999 and to the continued effects of
competition on rate adequacy. Approximately $40 million of the loss reserve
adjustment related to losses incurred in 1998 and prior years, with the balance
relating to losses incurred in 1999. In 1998, the Company reported a pre-tax
charge of $31 million for additional reinsurance premiums and loss reserves for
the regional segment. The increased losses in the commercial transportation unit
were the result of a rise in claim frequency and severity and of intense price
competition. Weather-related losses for the Company were $60 million in 1999
compared with $59 million in 1998. The overall increase in incurred losses in
1999 was partially offset by recoveries under the aggregate reinsurance cover
(see "Reinsurance") and by favorable reserve development on business written in
prior years by the specialty and alternative markets segments.

Other operating costs and expenses, which consist of the expenses of the
Company's insurance and alternative markets operations, as well as the Company's
corporate and investment expenses, increased by 9% to $605 million from $556
million in 1998. The increase in other operating costs is primarily due to a 10%
growth in premiums earned, which in turn results in an increase in underwriting
expenses. The consolidated expense ratio of the Company's insurance operations
(underwriting expenses expressed as a percentage of premiums written) increased
to 35.4% for the 1999 period from 34.9% for the comparable 1998 period due
primarily to higher reinsurance commissions rates for the specialty and
reinsurance segments. The regional expense ratio increased to 36.1% from 35.8%
due to the impact of additional reinsurance premiums and to certain costs
directly attributable to the restructuring. Adjusting for these items, the
regional expense ratio would have been 34.1% in 1999.

The Federal and foreign income tax benefit in 1999 was $46 million compared with
an expense of $5 million in 1998. The tax benefit in 1999, as compared to a tax
expense in 1998, was due to a loss before income taxes in 1999 and to an
increase in the percentage of revenues that are tax-exempt. In addition, the
1999 Federal income tax benefit reflects the closing with the Internal Revenue
Service of tax years 1992 through 1994. (See "Liquidity and Capital Resources.")

The 1999 results include an after-tax restructuring charge of $7 million, or
$.28 per diluted share, primarily related to the Company's restructuring of
certain of its operating units. The restructuring, which was substantially
completed in 1999, is expected to result in annual after-tax savings of
approximately $12 million. Under generally accepted accounting principles, the
restructuring charge does not include additional costs related to system
changes, financial incentives and other activities, although they are directly
related to the restructuring plan. The Company incurred such additional costs of
approximately $3 million, on an after-tax basis, in 1999.

As previously disclosed, during 1999 the Company adopted AICPA Statement of
Position 97-3, "Accounting By Insurance and Other Enterprises for
Insurance-Related Assessments." The adoption of this statement resulted in a
non-cash, after-tax charge of $3 million, or $.12 per diluted share, which is
reflected as a cumulative effect of a change in accounting principle.


                                                                              19
<PAGE>   3

The Company reported an after-tax extraordinary gain of $735,000 in 1999,
related to the repurchase and retirement of $10 million (face amount) of capital
trust securities. In 1998, the Company reported an after-tax extraordinary loss
of $5 million, related to the repurchase and retirement of $34.7 million (face
amount) of long-term debt.

OPERATING RESULTS FOR THE YEAR ENDED
DECEMBER 31, 1998 AS COMPARED TO THE YEAR
ENDED DECEMBER 31, 1997

Net income attributable to common stockholders for 1998 declined to $46 million,
or $1.59 per share diluted, from $91 million, or $3.02 diluted, in 1997.
Operating income in 1998 was $35 million or $1.19 per diluted share compared to
$83 million or $2.74 per diluted share in 1997. The decline in earnings was due
primarily to deterioration in underwriting results, attributable to an increase
in weather-related losses and the effects of competition on rate adequacy.

Net premiums written in 1998 rose 14% to $1,346 million from $1,178 million
written during 1997 due to growth recorded by all segments of the Company. Net
premiums written by the regional operations grew by 4% to $641 million from $619
million written in 1997. The growth was generated by the issuance of additional
policies. Net premiums written by the reinsurance segment increased by 30% to
$270 million from $207 million in 1997. This increase was substantially due to
an increase in pro rata treaty business. Net premiums written by the specialty
operations grew by 16% to $254 million from $219 million in 1997, due to
increases in all sectors of this business. This growth was due to an increase in
units insured. Net premiums written by the alternative markets operations grew
by 16% to $106 million from $91 million in 1997 due to the commencement of
operations of Key Risk Insurance Company (which underwrote business previously
managed on behalf of a self-insurance association). This increase more than
offset a decline in premiums written by Midwest Employers Casualty Company. Net
premiums written by the international operations grew by 79% to $75 million from
$42 million. This increase was due to 1997 acquisitions in Argentina and the
start-up of a life insurance and endowment insurance company in the Philippines.

Pre-tax net investment income increased to $202 million from $200 million earned
in 1997. This growth was due to an increase in investable assets produced by
cash flow from operations, which was partially offset by the effects of the
repurchase of common stock, and a decrease in pre-tax investment yield. The
decline in pre-tax investment yield was due to an increase in the percentage of
the portfolio invested in municipal bonds and lower yields earned on the trading
portfolio. (See "Liquidity and Capital Resources.")

Management fees and commissions consist primarily of fees earned by the
alternative markets segment. Management fees and commissions remained at $71
million as intense competition inhibited growth.

Realized investment gains increased to $25 million from $13 million in 1997.
Realized gains on fixed income securities resulted primarily from the Company's
strategy of maintaining an appropriate balance between the duration of its fixed
income portfolio and the duration of its liabilities; realized gains on equity
securities arise primarily as a result of a variety of factors which influence
the Company's valuation criteria for such securities. The majority of the 1998
realized gains resulted from the sale of fixed maturity securities while the
majority of 1997 realized gains resulted from the sale of equity securities.

The consolidated combined ratio (on a statutory basis) of the Company's
insurance operations increased to 106.6% in 1998 from 101.2% in 1997 mainly due
to an increase in the consolidated loss ratio. The consolidated loss ratio
(losses and loss expenses incurred expressed as a percentage of premiums earned)
increased to 71.2% from 66.4% due to a number of factors. Weather-related losses
for 1998 were $59 million compared with $33 million in 1997, which accounted for
an increase of 1.6% of the loss ratio. The regional operations were adversely
impacted by a rise in the frequency and sever-


20
<PAGE>   4

ity of commercial property and liability claims, especially in the fourth
quarter. The increase in severity resulted in an accrual for additional ceded
premiums due under certain sliding scale reinsurance treaties. These factors
were somewhat offset by favorable loss development on business written in prior
years.

Other operating costs and expenses, which consist of the expenses of the
Company's insurance and alternative markets operations, as well as the Company's
corporate and investment expenses, increased by 14% to $556 million from $488
million in 1997. The increase in other operating costs is primarily due to the
substantial premium growth discussed above, which in turn results in an increase
in underwriting expenses. The consolidated expense ratio of the Company's
insurance operations increased to 34.9% for the 1998 period from 34.4% for the
comparable 1997 period. This increase resulted primarily from the cost of
expansion incurred by several regional companies and higher growth rate in
international operations, which operate at a higher expense ratio than domestic
operations.

The Federal income tax provision resulted in an effective tax rate of 9% in 1998
(24% in 1997). The tax rate is lower than the statutory tax rate of 35% because
a substantial portion of investment income is tax-exempt. The decrease in the
effective tax rate in 1998 is due primarily to an increase in the percentage of
pre-tax income that is tax-exempt.

LIQUIDITY AND CAPITAL RESOURCES

GENERAL The Company's subsidiaries are highly liquid, receiving substantial cash
from premiums, investment income, management fees and proceeds from sales and
maturities of portfolio investments. The principal outflows of cash are payments
of claims, taxes, interest and operating expenses. The net cash provided from
operating activities (before trading account transactions) was $49 million in
1999, $224 million in 1998 and $229 million in 1997. The decrease in cash flow
in 1999 was primarily due to a higher level of claims activity. The 1998 cash
flow was impacted favorably by the assumption of a portfolio of loss reserves
for which the Company received proceeds of approximately $60 million.

As a holding company, the Company derives cash from its subsidiaries in the form
of dividends, tax payments and management fees. The Company is obligated to
service its debt, pay consolidated Federal income taxes and pay its expenses.
The Company also provides capital to its subsidiaries, including amounts
required under agreements with state insurance departments. Tax payments and
management fees from the insurance subsidiaries are made under agreements which
generally are subject to approval by state insurance departments. Maximum
amounts of dividends that can be taken without regulatory approval are
prescribed by statute. (See Note 18 of "Notes to Consolidated Financial
Statements.")

In addition to its other cash requirements in 2000, the Company is required to
repay $25 million of senior notes that mature on March 6, 2000 and to contribute
approximately $28 million to an insurance subsidiary during the first quarter of
2000. The Company anticipates receiving additional distributions from insurance
subsidiaries and borrowing under its credit facility to satisfy these
requirements.

FINANCING ACTIVITY During 1998, the Company issued $40 million face value of
6.375% medium term notes due April 15, 2005. Also in 1998, the Company
repurchased $34.7 million face amount of 9.875% and 8.7% senior notes and
debentures for $41.8 million and retired $10 million face value of 8.95% senior
notes upon maturity. In December 1998, one of the Company's subsidiaries issued
an $8 million five-year note. In 1999, the Company redeemed all outstanding
Series A Preferred Stock for $98 million and repurchased $10 million (face
value) of capital trust securities for $8.8 million.

During 1998, the Company purchased 3,172,222 shares of its common stock for
approximately $118 million. During 1999, the Company purchased 905,000 shares of
its common stock for approximately $22 million, leaving a balance as of December
31, 1999 of 1,095,000 shares available for repurchase under its current
authorization.


                                                                              21
<PAGE>   5


As of December 31, 1999 and 1998, the Company had $35 million and $55.5 million,
respectively, of outstanding short-term debt under its unsecured bank credit
facility. As of December 31, 1999, the Company had an additional $40 million of
short-term debt available under this facility. The credit facility expires on
and must be extended by December 8, 2000.

The Company has on file a "shelf" registration statement with the Securities and
Exchange Commission with a remaining balance of $150 million in additional
equity and/or debt securities. The securities may be offered from time to time
as determined by funding requirements and market conditions.

INVESTMENTS In its investment strategy, the Company establishes a level of cash
and highly liquid short-term and intermediate-term securities which, combined
with expected cash flow, is believed adequate to meet foreseeable payment
obligations. As part of this strategy, the Company attempts to maintain an
appropriate relationship between the average duration of the investment
portfolio and the approximate duration of its liabilities, i.e., policy claims
and debt obligations.

The Company's investment policy with respect to fixed maturity securities is
generally to purchase instruments with the expectation of holding them to their
maturity. However, active management of the portfolio is considered necessary to
maintain an approximate matching of assets and liabilities as well as to adjust
the portfolio as changes in financial market conditions alter the assumptions
underlying the purchase of certain securities.

The investment portfolio (including the trading account receivable from brokers
and clearing organizations and trading securities sold but not yet purchased),
on a cost basis, decreased in 1999 by $104 million to approximately $3,040
million primarily due to the repurchases of common and preferred stock discussed
above.

The Company's investments are currently comprised of fixed income securities and
trading account equity securities. At December 31, 1999, the portfolio mix of
the fixed income securities was as follows: tax-exempt securities were 40% (42%
in 1998); U.S. Government securities and cash equivalents were 24% (23% in
1998); mortgage-backed securities were 17% (18% in 1998); corporate fixed
maturity securities were 17% (15% in 1998); and the balance of 2% was invested
in other fixed income securities.

The Company had net trading account assets (trading account equity securities
plus trading account receivables from brokers and clearing organizations less
trading account equity securities sold but not yet purchased) of $356 million as
of December 31, 1999, as compared to $321 million as of December 31, 1998. The
net trading account assets represented approximately 12% and 10% of the
Company's net invested assets as of December 31, 1999 and 1998, respectively.

MARKET RISK The Company's market risk generally represents the risk of gain or
loss that may result from the potential change in the fair value of the
Company's investment portfolio as a result of fluctuations in prices, interest
rates and currency exchange rates. As discussed above, the Company attempts to
manage its interest rate risk by maintaining an appropriate relationship between
the average duration of the investment portfolio and the approximate duration of
its liabilities, i.e., policy claims and debt obligations.

The Company's investments are categorized as either fixed maturity securities or
equity securities. The principal market risk for the Company's fixed maturity
securities is interest rate risk. The Company uses various models and stress
test scenarios to monitor and manage interest rate risk. The following table
outlines the groups of fixed maturity securities and the components of the
interest rate risk:

reflect a portfolio's expected price movement as interest rates change. Based
upon a pricing model, the Company determines the estimated change in fair value
of the fixed maturity securities, assuming immediate parallel shifts in the
treasury yield curve while keeping spreads between individual securities and
treasury securities static. The fair value at specified levels at December 31,
1999 would be as follows:

==============================================================
</TABLE>

The estimated changes in fair value, based upon the above table, would be offset
by the Company's liabilities if they were marked to market.

The Company's equity securities are used primarily for merger arbitrage. Merger
arbitrage is the business of investing in the securities of publicly held
companies which are the targets in announced tender offers and mergers. Merger
arbitrage differs from other types of investments in its focus on transactions
and events believed likely to bring about a change in value over a relatively
short time period (usually four months or less). The Company believes that this
makes merger arbitrage investments less vulnerable to changes in general stock
market conditions. Potential changes in market conditions are also mitigated by
the implementation of hedging strategies, including short sales. Additionally,
the merger arbitrage positions are generally hedged against market declines by
purchasing put options, selling call options or entering into swap contracts.
Based upon these characteristics, the Company's equity securities are primarily
exposed to the completion of announced deals, which are subject to regulatory as
well as political and other risks.

The Company also has net assets held by its foreign subsidiaries that are
subject to foreign currency risk. As of December 31, 1999, the Company had $28
million (net of minority interest) invested in subsidiaries in Argentina, as
well as $7 million (net of minority interest) invested in subsidiaries in the
Philippines. As of December 31, 1999, approximately 81% and 49% of the invested
assets in Argentina and the Philippines, respectively, were denominated in US
Dollars. The effect of foreign subsidiaries maintaining US Dollar denominated
assets is an offset against fluctuations in foreign currency.

Argentina has established a currency board exchange rate mechanism that creates
a dollar for dollar relationship between the US Dollar and the Argentine Peso.
Because of this dollar for dollar relationship, devaluation risk is viewed to be
low.

The Company's investment in the Philippines is affected by fluctuations in the
exchange rate between the US Dollar and the Philippine Peso. For every one
percent change in the exchange rate, the Company's unrealized foreign currency
gain/(loss) would change approximately $73,000, net of minority interest.

FEDERAL AND FOREIGN INCOME TAXES The Company files a consolidated income tax
return in the U.S. and foreign tax returns in the countries of its overseas
operations. At December 31, 1999, the Company had a deferred tax liability of
$82 million, which primarily relates to deferred policy acquisition costs and
intangible assets, and a deferred tax asset of $164 million, which primarily
relates to the discounting of loss reserves for Federal income tax purposes,
unearned premiums, unrealized investment losses and an alternative minimum tax
credit carry forward.

The realization of the deferred tax asset is dependent upon the Company's
ability to generate sufficient taxable income in future periods. Based on
historical results and the prospects for current operations, management
anticipates that it is more likely than not that future taxable income will be
sufficient for the realization of this asset.


                                                                              23

REINSURANCE

The Company follows the customary industry practice of reinsuring a portion of
its exposures, paying to reinsurers a part of the premiums received on the
policies it writes. Reinsurance is purchased principally to reduce net liability
on individual risks and to protect against catastrophic losses. Although
reinsurance does not legally discharge an insurer from its primary liability for
the full amount of the policies, it does make the assuming reinsurer liable to
the insurer to the extent of the reinsurance coverage. The Company monitors the
financial condition of its reinsurers and attempts to place its coverages only
with substantial, financially sound carriers.

REGIONAL OPERATIONS In 1999, the Mid-Atlantic and Southern regional companies
generally retained $300,000 on individual property casualty risks while the
Midwest and New England companies generally retained $500,000 on individual
property casualty risks. The New England company retained up to $2.1 million per
bond for surety business. The other regional companies writing surety business
retained up to $450,000. The regional group also maintained catastrophe
reinsurance protection for approximately 100% of weather-related losses above $6
million per occurrence up to a maximum of $34 million. In addition, the regional
operating units carried additional aggregate catastrophe protection of 74% of
$4.5 million in excess of $7 million for storms exceeding $1.5 million.

Effective January 1, 1999, the Company purchased additional aggregate
reinsurance protection for the regional property casualty insurance segment.
Pursuant to the contract, the reinsurer will indemnify the regional companies
for losses occurring during 1999 in excess of 71% of earned premiums, up to a
limit of $35 million. Premiums of $21 million and losses of $35 million were
ceded to the reinsurer in 1999.

REINSURANCE OPERATIONS Signet Star's catastrophe retrocession program provides
coverage for property losses in five layers as follows: (i) 100% of $7.5 million
in excess of $6 million per occurrence; (ii) 95% of $6.5 million in excess of
$13.5 million per occurrence; (iii) 95% of $10 million in excess of $20 million
per occurrence; (iv) 95% of $10 million in excess of $30 million per occurrence;
and (v) 100% of $25 million (for California only and only under certain
conditions) and 100% of $10 million (for Florida only and only under certain
conditions). In 1999, Signet Star had a variable quota share program on its
casualty facultative business with retentions varying from $425,000 up to $2.5
million depending on the certificate limit. Property facultative business is
covered on a per risk basis for $700,000 in excess of $300,000 and 98.5% of $4
million in excess of $1 million. These coverages apply to Signet Star's
individual certificate and master certificate business. During 1999, Signet Star
had retrocession coverage for its fidelity and surety business for 100% of each
loss up to $2.5 million in excess of $750,000 per occurrence and 100% of each
loss up to $2.5 million in excess of $3.25 million per occurrence and 86.5% of
each surety loss up to $13 million in excess of $5.75 million per occurrence.
During 1999, the Latin American and Caribbean division retained $250,000 per
risk for property, marine, energy and aviation business and $500,000 per risk
for casualty.

SPECIALTY OPERATIONS Admiral's retention in 1999 was $183,750 from January 1 to
June 30 and $173,750 from July 1 to December 31 per risk for most classes of
business. Retentions varied between $2 million and $5 million based upon policy
size, per insured, for business written by Monitor Liability Managers. Nautilus
generally retained $140,000 per risk in 1999 and Carolina maintained its
retention at $300,000 on property liability exposures. In 1999, Carolina (on
business underwritten by Monitor Surety Managers) retained up to $500,000 on a
per principal basis. Great Divide retained $140,000 per risk in 1999. The
specialty group (except Carolina) is also covered under the regional group's
property catastrophe protection for 100% of $34 million in excess of $6 million.

<PAGE>   8

ALTERNATIVE MARKETS OPERATIONS Midwest Employers' retention is generally $1
million per occurrence above the self-insured's underlying retention. Key Risk
Insurance Company's retention in 1999 was $300,000 per risk. Signet Star's
alternative markets operation maintains specific retrocessional coverage on
certain treaties and is also covered under the reinsurance group's catastrophe
retrocessional program. Preferred Employers' retention in 1999 was $250,000 per
risk.

INTERNATIONAL OPERATIONS The international operations generally retained between
$50,000 and $250,000 per occurrence or individual risk.

Year 2000

the Company's critical primary operating software was modified or replaced as
necessary for Year 2000 compliance, and the Company did not experience any
significant disruption or other adverse impact on its business at January 1,
2000 or thereafter as a result of the Year 2000 date change.

It is the Company's practice in the normal course of business to upgrade
technology, including hardware and software, as appropriate. As a result of this
practice, much of the Company's Year 2000 readiness was accomplished in the
ordinary course. Through December 31, 1999, the Company incurred approximately
$7 million of costs for Year 2000 compliance.

The Year 2000 issue may be a concern for the Company from an underwriting
standpoint to the extent of possible liability for coverage under general
liability, property, directors and officers liability and other policies.
Through December 31, 1999, no significant losses have arisen or come to light
with respect to Year 2000 claims exposure for the Company's insurance and
reinsurance subsidiaries. Additionally, certain of the Company's insurance
subsidiaries may either include or exclude insurance coverage for Year 2000
exposures. However, claims have been made against other insurers seeking
recovery of costs incurred to achieve Year 2000 compliance. While these or other
kinds of Year 2000 claims against insurers may not prove successful, there
exists a potential for judicial decisions which reformulate policies to expand
their coverage for previously unforeseen theories of liability which may produce
unanticipated claims. As a result, and because there is no prior history of such
claims, the amount of any such potential Year 2000 coverage liabilities is not
determinable.

The discussion herein with regard to Year 2000 matters contains forward-looking
statements within the meaning of the Private Securities Litigation Reform Act of
1995. These statements are subject to certain risks and uncertainties that could
cause actual results to differ materially from those reflected in such
forward-looking statements. The inclusion of such forward-looking statements
herein shall not be considered a representation by the Company that the
objectives, plans or expectations of the Company, or other matters addressed by
the forward-looking statements, will be achieved.

CAPITALIZATION

For the year ended December 31, 1999, stockholders' equity decreased by
approximately $270 million. The decrease in stockholders' equity is primarily
attributable to the Company's repurchase of shares of its common and preferred
stock for approximately $120 million; to an after-tax decline in unrealized
investment gains (losses) of approximately $99 million; and to a net loss of $37
million. Accordingly, the Company's total capitalization decreased to $1,185
million at December 31, 1999 and the percentage of the Company's capital
attributable to long-term debt increased to 33% at December 31, 1999 from 27% at
December 31, 1998.

NOTES TO CONSOLIDATED FINANCIAL STATEMENTS
For the years ended December 31, 1999, 1998 and 1997

(1) SUMMARY OF SIGNIFICANT ACCOUNTING POLICIES

(A) Principles of consolidation and basis of presentation
The consolidated financial statements, which include the accounts of W. R.
Berkley Corporation and its subsidiaries ("the Company"), have been prepared on
the basis of generally accepted accounting principles ("GAAP"). All significant
intercompany transactions and balances have been eliminated. Reclassifications
have been made in the 1998 and 1997 financial statements to conform them to the
presentation of the 1999 financial statements. The preparation of financial
statements in conformity with GAAP requires management to make estimates and
assumptions that affect the reported amounts of assets and liabilities and
disclosures of contingent assets and liabilities at the date of the financial
statements and the revenues and expenses reflected during the reporting period.
Actual results could differ from those estimates.

(B) Revenue recognition
Insurance premiums written are recognized as earned generally on a pro-rata
basis over the contract period. Management fees on insurance service contracts
are recorded as earned primarily on a pro-rata basis over the policy period.
Commission income is recognized as earned on the effective date of the
applicable insurance policies.

(C) Investments
The Company has classified its investments into three categories. Securities
that the Company has the positive intent and ability to hold to maturity are
classified as "held to maturity" and reported at amortized cost. Securities
which the Company purchased with the intent to sell in the near-term are
classified as "trading" and are reported at estimated fair value, with
unrealized gains and losses reflected in the statement of operations. The
remaining securities are classified as "available for sale" and carried at
estimated fair value, with unrealized gains and losses, net of applicable income
taxes, excluded from earnings and reported as comprehensive income (loss) and a
separate component of stockholders' equity. Fair value is generally determined
using published market values.

Realized gains or losses represent the difference between the cost of securities
sold and the proceeds realized upon sale. The cost of securities is adjusted
where appropriate to include a provision for significant decline in value which
is considered to be other than temporary. The Company uses the specific
identification method where possible, and the first-in, first-out method in
other instances, to determine the cost of securities sold. Realized gains or
losses, including any provision for decline in value, are included in the
statement of operations.

(D) Trading account
The long portfolio positions are presented in the balance sheet as trading
account assets. The short sales and short call options used in trading account
activities are presented as trading securities sold but not yet purchased. The
trading account receivable from brokers and clearing organizations is comprised
of unsettled trades within the trading account and the net margin balances held
by the clearing broker.

(E) Per share data
Basic per share data is based upon the weighted average number of shares
outstanding during the year. Diluted per share data reflects the potential
dilution that would occur if employee stock-based compensation plans were
exercised. Shares issued in connection with loans to shareholders are not
considered to be outstanding for the purposes of calculating basic per share
amounts and have been excluded from stockholders' equity.

(F) Deferred policy acquisition costs
Acquisition costs (primarily commissions and premium taxes) incurred in writing
insurance and reinsurance business are deferred and amortized ratably over the
terms of the related contracts. Deferred policy acquisition costs are limited to
the amounts estimated to be recoverable from the applicable unearned premiums
and the related anticipated investment income by giving effect to anticipated
losses, loss adjustment expenses and expenses necessary to maintain the
contracts in force.

(G) Reserves for losses and loss expenses
Reserves for losses and loss expenses are an accumulation of amounts determined
on the basis of (1) evaluation of claims for business written directly by the
Company; (2) estimates received from other companies for reinsurance assumed;
and (3) estimates for losses incurred but not reported (based on Company and
industry experience). These estimates are


30
<PAGE>   14

periodically reviewed and, as experience develops and new information becomes
known, the reserves are adjusted as necessary. Such adjustments are reflected in
results of operations in the period in which they are determined.

The Company discounts its liabilities for excess workers' compensation ("EWC")
losses and loss expenses using a "risk-free" rate. EWC liabilities are
discounted because of the long period of time over which it pays losses. The
Company believes that utilizing a "risk-free" rate to discount these reserves
more closely reflects the economics associated with the EWC line of business
(see Note 15 of notes to consolidated financial statements).

(H) Reinsurance ceded
Ceded unearned premiums are reported as prepaid reinsurance premiums and
estimated amounts of reinsurance recoverable on unpaid losses are included in
due from reinsurers. To the extent any reinsurer does not meet its obligations
under reinsurance agreements, the Company must discharge the liability. Amounts
due from reinsurers are reflected net of funds held where the right of offset is
present. The Company has provided reserves for uncollectible reinsurance.

(I) Excess of cost over net assets acquired
Costs in excess of the net assets of subsidiaries acquired are being amortized
on a straight-line basis over 25 to 40 years. The Company continually evaluates
the amortization period of its intangible assets. Estimates of useful lives are
revised when circumstances or events indicate that the original estimate is no
longer appropriate. Amortization (including adjustments) of the excess of cost
over net assets acquired was $3,866,000, $3,178,000 and $2,950,000 for 1999,
1998 and 1997, respectively.

(J) Federal and foreign income taxes
The Company files a consolidated income tax return in the U.S. and foreign tax
returns in the countries of its overseas operations.

The Company's method of accounting for income taxes is the asset and liability
method. Under the asset and liability method, deferred tax assets and
liabilities are measured using tax rates currently in effect or expected to
apply in the years in which those temporary differences are expected to reverse.

(K) Stock options
The Company accounts for its stock options in accordance with Financial
Accounting Standards Board ("FASB") Statement No. 123, "Accounting for
Stock-Based Compensation" (FAS 123), which provides that stock-based
compensation may be disclosed in the footnotes to financial statements.

(L) Foreign currency
Revenues and expenses in foreign currencies are translated at the weighted
average exchange rate during the year. Assets and liabilities are translated at
the rate of exchange in effect at the close of the period. Unrealized gains or
losses (losses of $3,352,000 and $3,293,000 as of December 31, 1999 and 1998,
respectively) resulting from translating foreign currency financial statements
are reported as a component of common stockholders' equity. Gains or losses
(losses of $381,000 for 1999 and gains of $1,543,000 and $1,408,000 for 1998 and
1997, respectively) resulting from foreign currency transactions (transactions
denominated in a currency other than the entity's functional currency) are
included in other income (gains) or other operating costs and expenses (losses)
in the statement of operations.

(M) Real estate, furniture and equipment
Real estate, furniture and equipment are carried at cost less accumulated
depreciation. Depreciation is calculated using the estimated useful lives of the
respective assets. Depreciation expense was $16,291,000, $17,114,000 and
$12,799,000 for 1999, 1998 and 1997, respectively.

(N) Other Comprehensive Income (loss)
Comprehensive income (loss) encompasses all changes in stockholder's equity
(except those arising from transactions with shareholders) and includes net
income, net unrealized capital gains or losses on available-for-sale securities
and unrealized foreign currency translation adjustments.

(O) Insurance Related Assessments
As of January 1, 1999, the Company adopted the American Institute of Certified
Public Accountants (AICPA) Statement of Position ("SOP") 97-3, "Accounting by
Insurance and Other Enterprises for Insurance Related Assessments." This
statement provides guidance for determining when an entity should recog-


                                                                              31
<PAGE>   15

nize liabilities for guarantee fund and other insurance related assessments, how
to measure those liabilities and when an asset may be recognized for the
recovery of such assessments through premium tax offsets or policy surcharges.
The adoption of this statement resulted in an after tax charge of $3,250,000 for
the year ended December 31, 1999, which is reflected as a cumulative effect of a
change in accounting principle.

(P) RECENT ACCOUNTING PRONOUNCEMENTS
During 1999, the FASB issued FAS 137, "Accounting for Derivative Instruments and
Hedging Activities - Deferral of the Effective Date of FASB 133, and Amendment
of FASB 133" which extended the effective date of FAS 133 to January 1, 2001.
FAS 133, "Accounting for Derivative Instruments and Hedging Activities,"
establishes accounting and reporting standards for derivative instruments. This
statement will not have a material impact on the Company's results of operations
or financial condition.

(2) ACQUISITIONS
During 1999, 1998 and 1997, several international and other acquisitions were
completed for an aggregate consideration of approximately $1,533,000,
$13,389,000 and $7,238,000, respectively. The acquisitions were accounted for as
purchases and, accordingly, the results of operations of the companies have been
included from the respective dates of acquisition. Proforma results of
operations have been omitted as such effects are not significant.

    Net assets of the acquired companies for 1999, 1998 and 1997 were as
follows: Investments in fixed maturity and equity securities of $0, $1,786,000
and $2,192,000; cash and invested cash of $0, $10,085,000 and $7,823,000; excess
of cost over net assets acquired of $3,744,000, $6,847,000 and $2,688,000; and
other liabilities, net of other assets of $5,277,000, $5,329,000 and $5,465,000.

(3) COMMITMENTS, LITIGATION AND CONTINGENT LIABILITIES
Neither the Company nor any of its subsidiaries is engaged in any litigation
known to the Company which management believes will have a material adverse
effect upon the Company's business. As is common with other insurance companies,
the Company's subsidiaries are regularly engaged in the defense of claims
arising out of the conduct of the insurance business.

(4) LEASE OBLIGATIONS
The Company and several of its subsidiaries use office space and equipment under
leases expiring at various dates through September 1, 2004. These leases are
considered operating leases for financial reporting purposes. Some of these
leases have options to extend the length of the leases and contain clauses for
cost of living, operating expense and real estate tax adjustments. Rental
expense was approximately: $16,109,000, $14,095,000 and $12,564,000 for 1999,
1998 and 1997, respectively. Future minimum lease payments (without provision
for sublease income) are $13,059,000 in 2000; $9,887,000 in 2001; $7,611,000 in
2002; $5,653,000 in 2003; and $4,368,000 thereafter.

(5) RESTRUCTURING PLAN
In the first quarter of 1999, the Company implemented a plan to restructure
certain of its operating units. Under the plan, the Company consolidated ten of
its regional units into four; merged two of its alternative market units; and
combined two of its international units. In connection with the restructuring
plan, the Company expects to reduce its workforce by approximately 386
employees. The Company reported a restructuring charge of $11,505,000 in the
first quarter of 1999 to reflect the estimated costs of the plan. These charges
consist mainly of severance payments of $7,562,000, contractual lease payments
related to abandoned facilities and abandoned equipment and property owned. The
activities under the plan were substantially completed in 1999. The Company has
paid $6,916,000 related to the restructuring charge of which $4,221,000 relates
to severance payments. The remaining restructuring accrual is $4,589,000 at
December 31, 1999.

(1)Floating rate equal to Libor plus 50 basis points.

The difference between the face value of long-term debt and the carrying value
is unamortized discount. All outstanding long-term debt is not redeemable until
maturity and ranks on a parity with all other outstanding indebtedness of the
Company.

   The Company has on file a "shelf" registration statement with the Securities
and Exchange Commission with a remaining balance of $150,000,000 in additional
equity and/or debt securities. The securities may be offered from time to time
as determined by funding requirements and market conditions.

SHORT-TERM DEBT As of December 31, 1999 and 1998, the Company had $35,000,000
and $55,500,000, respectively, of outstanding short-term debt under its
unsecured line-of-credit. During 1999 and 1998, the average interest rate of the
Company's short-term debt was 5.36% and 5.59%. As of December 31, 1999, the
Company had an additional $40,000,000 of short-term debt available under its
line-of-credit.


(7) COMPANY-OBLIGATED MANDATORILY REDEEMABLE CAPITAL SECURITIES OF A SUBSIDIARY
TRUST HOLDING SOLELY JUNIOR SUBORDINATED DEBENTURES OF THE CORPORATION DUE
DECEMBER 15, 2045

The Company-obligated mandatorily redeemable preferred securities of a
subsidiary trust holding solely junior subordinated debentures ("Capital Trust
Securities") were issued by the W.R. Berkley Capital Trust ("the Trust") in
1996. All of the common securities of the Trust are owned by the Company. The
sole assets of the Trust are $210,000,000 aggregate principal amount of 8.197%
Junior Subordinated Debentures due December 15, 2045, issued by the Company (the
"Junior Subordinated Debentures"). The Company's guarantee of payments of cash
distributions and payments on liquidation of the Trust and redemption of the
Capital Trust Securities, when taken together with the Company's obligations
under the Trust Agreement under which the Capital Trust Securities were issued,
the Junior Subordinated Debentures and the Indenture under which the Junior
Subordinated Debentures were issued, including its obligations to pay costs,
expenses, debts and liabilities of the Trust (other than with respect to the
Capital Trust Securities), provide a full and unconditional guarantee of the
Trust's obligations under the Capital Trust Securities. The Company records the
preferential cumulative cash dividends arising from the payments of interest on
the Junior Subordinated Debentures as interest expense in its consolidated
statement of operations.

    The Capital Trust Securities are subject to mandatory redemption in a like
amount (i) in whole but not in part, on the stated maturity date, upon repayment
of the Junior subordinated Debentures, (ii) in whole but not in part, at any
time contemporaneously with the optional prepayment of the Junior Subordinated
Debentures by the Company upon the occurrence and continuation of a certain
event and (iii) in whole or in part, on or after December 15, 2006,
contemporaneously with the optional prepayment by the Company of Junior
Subordinated Debentures. In September 1999, a subsidiary of the Company
purchased $10 million (face amount) of the Capital Trust Securities for
$8,774,000.


                                                                              33

(8) REINSURANCE CEDED
The Company follows the customary industry practice of reinsuring a portion of
its exposures principally to reduce net liability on individual risks and to
protect against catastrophic losses. The following amounts arising under
reinsurance ceded contracts have been deducted in arriving at the amounts
reflected in the statement of operations:

</TABLE>

Effective January 1, 1999, the Company purchased additional aggregate
reinsurance protection for its regional segment. Pursuant to the contract, the
reinsurer will indemnify the regional companies for losses occuring during 1999
in excess of 71% of earned premiums, up to a limit of $35,000,000. Premiums of
$21,000,000 and losses of $35,000,000 were ceded to the reinsurer in 1999.

The Company applies APB Opinion 25 and related interpretations in accounting for
these plans. Accordingly, no compensation cost has been recognized for the stock
option plans. Had compensation cost for the Company's stock option plans been
determined based on the fair value at the grant dates for awards under those
plans consistent with the method of SFAS No. 123, the Company's net income and
earnings per share would have been reduced to the pro forma amounts indicated
below (000's omitted except per share data):

(11) COMPENSATION PLAN

The Company and its subsidiaries have profit sharing retirement plans in which
substantially all employees participate. The plans provide for minimum annual
contributions of 5% of eligible compensation; contributions above the minimum
are discretionary and vary with each participating subsidiary's profitability.
Employees become eligible to participate in the Retirement Plans on the first
day of the month following the first full three months in which they are
employed. Profit sharing expense amounted to $7,768,000, $8,524,000 and
$8,402,000 for 1999, 1998 and 1997, respectively.

    In May 1997, the Common Stockholders approved the Long-Term Incentive
Compensation Plan ("LTIP"). The LTIP provides for incentive compensation to key
executives, is based on long-term corporate performance and is based upon
criteria established by the Compensation and Stock Option Committee of the Board
of Directors (the "Committee"). Key employees are awarded participation units
("units") as determined by the Committee. The Units vest and become exercisable
over a maximum term of five years from the date of their award. The units are
payable in cash or up to 50% in shares of Common Stock. In 1997, 266,250 units
were awarded which amounted to an expense of $1,705,000. There was no LTIP
expense in 1998 or 1999.

(a) The primary focus of the trading account is merger arbitrage. Merger
    arbitrage is the business of investing in the securities of publicly held
    companies which are the targets in announced tender offers and mergers.
    Merger arbitrage differs from other types of investments in its focus on
    transactions and events believed likely to bring about a change in value
    over a relatively short time period (usually four months or less). The
    Company believes that this makes merger arbitrage investments less
    vulnerable to changes in general financial market conditions. Potential
    changes in market conditions are also mitigated by the implementation of
    hedging strategies, including short sales.

    The arbitrage positions are generally hedged against market declines by
    purchasing put options, selling call options or entering into swap
    contracts. Therefore, just as long portfolio positions may incur losses
    during market declines, hedge positions may also incur losses during market
    advances. As of December 31, 1999, the notional amount of long option
    contracts outstanding is $36,331,000 and short option contracts outstanding
    is $50,797,000.

    Investment income earned from net trading account activity includes
    unrealized trading losses of $4,897,000 for 1999 and unrealized trading
    gains of $1,291,000 and $13,737,000 for 1998 and 1997, respectively.

(13) STOCKHOLDERS' EQUITY

COMMON EQUITY The Company has calculated per share data in accordance with FAS
128. Treasury shares have been excluded from average outstanding shares from the
date of acquisition. The weighted average number of shares used in the
computation of basic earnings per share was 25,823,000, 28,194,000 and
29,503,000 for 1999, 1998 and 1997, respectively. The weighted average number of
shares used in the computations of diluted earnings per share was 25,927,000,
29,115,000 and 30,185,000 for 1999, 1998 and 1997, respectively. The difference
in calculating basic and diluted earnings per share is attributable entirely to
the dilutive effect of stock-based compensation plans.

    Changes in shares of Common Stock outstanding, net of treasury shares, are
as follows:

PREFERRED EQUITY   During 1997, the Company purchased 276,855 shares of Series A
Preferred Stock for an aggregate cost of $41,523,000. On January 25, 1999, all
remaining outstanding shares of the Series A Preferred Stock were redeemed for
$98,092,000.

   On May 11, 1999, the Company declared a dividend distribution of one Right
for each outstanding share of Common Stock. Each Right entitles the holder to
purchase a unit consisting of one one-thousandth of a share of Series A Junior
Participating Preferred Stock at a purchase price of $120 per unit (subject to
adjustment) upon the occurrence of certain events relating to potential changes
in control of the Company. The Rights expire on May 11, 2009, unless earlier
redeemed by the Company as provided in the Rights Agreement.

Federal income tax expense (benefit) applicable to realized investment gains
(losses) was ($2,122,000), $8,890,000 and $4,615,000 in 1999, 1998 and 1997,
respectively. The Company had a current income tax receivable of $8,939,000 and
$10,532,000 at December 31, 1999 and 1998, respectively. The Company's tax
returns through December 31, 1994 have been examined by the Internal Revenue
Service.

    The realization of the deferred tax asset is dependent upon the Company's
ability to generate sufficient taxable income in future periods. Based on
historical results and the prospects for current operations, management
anticipates that it is more likely than not that future taxable income will be
sufficient for the realization of this net asset.

The balance sheet includes $20,348,000 and $6,043,000 as of december 31, 1999
and 1998, respectively, relating to reserves for life insurance which are not
included in the table above, and the statement of operations includes
$14,913,000 and $3,693,000 for the years ended december 31, 1999 and 1998,
respectively, relating to the policyholder benefits incurred on life insurance
which are not included in the above table. The 1999 increase in reserves related
to prior years is due to reserve strengthening in the regional segment partially
offset by favorable reserve development in the specialty and alternative markets
segments.

    Due to the nature of Excess Workers Compensation ("EWC") business and the
long period of time over which losses are paid in this line of business, the
Company discounts the liability for losses and loss expenses established for the
EWC line of business. Discounting liabilities for losses and loss expenses gives
recognition to the time value of money. Discounting is intended to appropriately
match losses and loss expenses to income earned on investment securities
supporting the liabilities. The expected losses and loss expense payout pattern
subject to discounting was derived from the Company's loss payout experience and
is supplemented with data compiled from insurance companies writing workers'
compensation on an excess-of-loss basis. The expected payout pattern has a very
long duration because it reflects the nature of losses generally which penetrate
self-insured retention limits contained in EWC policies. The Company has limited
the estimated payout duration to 30 years in order to introduce an additional
level of conservatism into the discounting process. The liabilities for losses
and loss expenses have been discounted using "risk-free" discount rates
determined by reference to the U.S. Treasury yield curve weighted for the EWC
premium volume to reflect the seasonality of the anticipated duration of losses
associated with such coverages. The weighted average discount rate for accident
years 1999, 1998, 1997, 1996 and 1995 and prior is 5.90%, 5.90%, 5.98%, 5.90%
and 5.80%, respectively. The aggregate net discount, after reflecting the
effects of ceded reinsurance, is $186,981,000, $186,964,000 and $189,600,000 at
December 31, 1999, 1998 and 1997, respectively. For statutory purposes, the
Company uses a discount rate of 3.0% as permitted by the Department of Insurance
of the State of Ohio.

    To date, known pollution and environmental claims at the insurance company
subsidiaries have not had a material impact on the Company's operations.
Environmental claims have not materially impacted the Company because its
subsidiaries generally did not insure larger industrial companies which are
subject to significant environmental exposures.

    The Company's net reserves for losses and loss adjustment expenses relating
to pollution and environmental claims were $30,944,000 and $33,391,000 at
December 31, 1999 and 1998, respectively. The Company's gross reserves for
losses and loss adjustment expenses relating to pollution and environmental
claims were $65,966,000 and $69,283,000 at December 31, 1999 and 1998,
respectively. Net incurred losses and loss expenses for reported pollution and
environmental claims were approximately $1,371,000, $2,227,000 and $79,000 in
1999, 1998 and 1997, respectively. Net paid losses and loss expenses were
approximately $3,819,000, $2,614,000 and $2,175,000 in 1999, 1998 and 1997,
respectively. The estimation of these liabilities is subject to significantly
greater than normal variation and uncertainty because it is difficult to make a
reasonable actuarial estimate of these liabilities due to the absence of a
generally accepted actuarial methodology for these exposures and the potential
effect of significant unresolved legal matters, including coverage issues as
well as the cost of litigating the legal issues. Additionally, the determination
of ultimate damages and the final allocation of such damages to financially
responsible parties are highly uncertain.

(16) INDUSTRY SEGMENTS

The Company's operations are presently conducted through five basic segments:
specialty; alternative markets; reinsurance; regional; and international. The
specialty lines of insurance consist primarily of excess and surplus lines,
commercial transportation, professional liability, directors and officers
liability and surety. The Company's alternative markets segment specializes in
insuring, reinsuring and administering self-insurance programs and other
alternative risk transfer mechanisms for public entities, private employers and
associations. The Company's reinsurance segment specializes in underwriting
property, casualty and surety reinsurance on both a treaty and facultative
basis. The regional property casualty insurance segment writes standard

intercompany debt and fees paid by subsidiaries for portfolio management and
other services to the Company. Identifiable assets by segment are those assets

</TABLE>

The estimated fair value of investments is based on quoted market prices as of
the respective reporting dates. The fair value of the long-term debt is based on
rates available for borrowings similar to the Company's outstanding debt as of
the respective reporting dates.

(18) DIVIDENDS FROM SUBSIDIARIES AND STATUTORY FINANCIAL INFORMATION

The Company's insurance subsidiaries are restricted by law as to the amount of
dividends they may pay without the approval of regulatory authorities. During
2000, the maximum amount of dividends which can be paid without such approval is
approximately $77,264,000.

    Combined net income and policyholders' surplus of the Company's consolidated
insurance subsidiaries, as determined in accordance with statutory accounting
practices, are as follows:

<TABLE>
<CAPTION>
(Dollars in thousands)          1999         1998       1997
- ------------------------------------------------------------
<S>                        <C>           <C>        <C>
Net income (loss)          $ (34,598)    $ 67,014   $121,300
============================================================
Policyholders' surplus      $865,672     $941,853   $971,749
============================================================
</TABLE>

The significant variances between statutory accounting practices and GAAP are:
For statutory purposes, bonds are carried at amortized cost, acquisition costs
are charged to operations as incurred, deferred federal income taxes are not
provided for temporary differences between book and tax assets and liabilities,
EWC reserves are discounted at a 3.0% rate and certain assets designated as
"non-admitted assets" are charged against surplus.

    At December 31, 1999 and 1998, bonds with a fair value of $209,485,000 and
$185,206,000 were on deposit with various state insurance departments as
required by state laws.

    The National Association of Insurance Commissioners ("NAIC") has risk-based
capital ("RBC") requirements that require insurance companies to calculate and
report information under a risk-based formula which measures statutory capital
and surplus needs based on a regulatory definition of risk in a company's mix of
products and its balance sheet. RBC did not affect the operations of the
Company's insurance subsidiaries since all of its subsidiaries have an RBC
amount above the authorized control level RBC, as defined by the NAIC.

    The NAIC recently completed a process intended to codify statutory
accounting practices for certain insurance enterprises. As a result of this
process, the NAIC will issue a revised statutory accounting practices and
procedures manual, which will be effective January 1, 2001. The Company has not
yet determined the impact that this change will have on the statutory capital
and surplus of its insurance subsidiaries.


                                                                              41

INDEPENDENT AUDITORS' REPORT

Board of Directors and Stockholders
W.R. Berkley Corporation

We have audited the consolidated balance sheets of W. R. Berkley Corporation and
subsidiaries as of December 31, 1999 and 1998, and the related consolidated
statements of operations, stockholders' equity, comprehensive income and cash
flows for each of the years in the three-year period ended December 31, 1999.
These consolidated financial statements are the responsibility of the Company's
management. Our responsibility is to express an opinion on these consolidated
financial statements based on our audits.

We conducted our audits in accordance with generally accepted auditing
standards. Those standards require that we plan and perform the audit to obtain
reasonable assurance about whether the financial statements are free of material
misstatement. An audit includes examining, on a test basis, evidence supporting
the amounts and disclosures in the financial statements. An audit also includes
assessing the accounting principles used and significant estimates made by
management, as well as evaluating the overall financial statement presentation.
We believe that our audits provide a reasonable basis for our opinion.

In our opinion, the consolidated financial statements referred to above present
fairly, in all material respects, the financial position of W. R. Berkley
Corporation and subsidiaries at December 31, 1999 and 1998, and the results of
their operations and their cash flows for each of the years in the three-year
period ended December 31, 1999, in conformity with generally accepted accounting
principles.

As discussed in Note 1 to the consolidated financial statements, the Company has
changed its method of accounting for insurance-related assessments in 1999.
