PART I

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 (conducted through Signet Star Holdings, Inc.); specialty lines of insurance (including excess and surplus lines and commercial transportation); alternative markets (including the management of alternative insurance market mechanisms); and international (conducted through Berkley International, LLC). 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 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 Midwestern, Southern and Northeastern sections 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, 1997 were as follows:

Loss and Loss Adjustment Expense Reserves

In the property casualty industry, it is not unusual for significant periods of time, ranging up to several years or more, 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 business, as discussed below, the Company does not discount its reserves to estimated present value for financial reporting purposes.

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 the computation of ultimate losses.

In examining reserve adequacy, historical data is reviewed and consideration is given to such factors as 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, judgmentally adjusted 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, resulting 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 historic 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 their coverage to previously unforeseen theories of liability, including 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. With respect to year 2000 claims exposure for our insurance and reinsurance subsidiaries, to date, no significant losses have arisen. However, due to the potential judicial decisions which re-formulate policies to expand their coverage to previously unforeseen theories of liabilities which may produce unanticipated claims, at this point in time, the estimation of any potential year 2000 liabilities is not determinable.

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 Midwest's 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 1997, 1996 and 1995 and prior was approximately 5.98%, 5.90% and 5.80%, respectively. The aggregate net discount, after reflecting the effects of ceded reinsurance, is $189,600,000, $172,415,000 and $152,235,000 at December 31, 1997, 1996 and 1995, 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 $33.1 million and $35.2 million at December 31, 1997 and 1996, respectively. The Company's gross reserves for losses and loss adjustment expenses relating to pollution and environmental claims were $68.4 million and $71.9 million at December 31, 1997 and 1996, respectively. Net incurred losses and loss expenses for reported pollution and environmental claims were approximately $0.1 million, $6.9 million and $8.0 million in 1997, 1996 and 1995, respectively. Net paid losses and loss expenses has averaged approximately $3 million for each of the last three years. 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 is highly uncertain.

(1) Claims occurring during the current year is net of discount of $29,783,000, 28,885,000 and $708,000 for the years ended December 31, 1997, 1996 and 1995, respectively.

(2) For statutory purposes, Midwest uses a discount rate of 3.0% as permitted by the Department of Insurance of the State of Ohio. For GAAP purposes, Midwest uses a discount rate based on the U. S. Treasury yield curve weighted for the expected payout period, as described above.

The following table presents the development of net reserves for 1986 through 1997. 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 1986 reserves have developed a $47 million deficiency 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 1987 is reserved for $2,000 as of December 31, 1987. Assuming this claim was settled for $2,300 in 1997, the $300 deficiency would appear as a deficiency in each year from 1987 through 1996.

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. In general, the Company's regional property casualty subsidiaries as well as Carolina, Great Divide and Midwest 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 operate 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.

Various state and federal organizations, including Congressional committees and the National Association of Insurance Commissioners ("NAIC"), have been conducting investigations 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 effect 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. 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.

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. The NAIC has proposed and certain states have adopted legislation that lowers the threshold amount for determining what constitutes an extraordinary dividend. Such legislative changes could make it more difficult for insurance subsidiaries to pay dividends to their parents. Similarly, the NAIC has proposed a new model investment law that may affect the statutory carrying values of certain investments; however, the final outcome of that proposal is not certain, nor is it possible to predict what impact the proposal will have on the Company or whether the proposal will be adopted in the foreseeable future.

Tax Law Changes

There were no tax law changes in 1997 that significantly affected the Company.

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.

Signet Star's competition comes from domestic and foreign reinsurers, some of which have greater financial resources than Signet Star who 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. In addition, there are regional and 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 and large national multi-line companies.

Midwest's competition comes from insurance and reinsurance companies, some of which have greater financial resource than Midwest. Most of theses carriers write specific EWC

19

coverage, do not offer aggregate EWC coverage and tend to focus on risks larger than those targeted by Midwest. In addition, Midwest 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 maybe related to government entities, as well as with branch or local subsidiaries of multi-national companies.

Employees

As of March 2, 1998, the Company employed 4,046 persons. Of this number, the Company's subsidiaries employed 3,999 persons, of whom 2,283 were executive and administrative personnel and 1,716 were clerical personnel. The Company employed the remaining 47 persons in its parent company and investment operations, of whom 38 were executive and administrative personnel and 9 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 reporting period.

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.

The Company currently does not engage in material operations in foreign countries nor is a material portion of its revenues presently derived from customers in foreign countries. In 1995, the Company entered into a joint venture to acquire insurance and insurance related operations outside the United States (see "International Operations"). However, the Company's insurance subsidiaries regularly purchase a portion of their catastrophe reinsurance coverage from foreign reinsurers, including syndicate members of Lloyd's of London. While Queen's Island is domiciled in Bermuda, to date its business has exclusively been reinsurance of its domestic affiliates.

On July 1, 1993, the Company exchanged all the stock of Signet Reinsurance Company ("Signet") for 60% of the stock of Signet Star, a newly formed holding company. Signet Star simultaneously acquired all the stock of North Star Reinsurance Company ("North Star Reinsurance") from General Re in exchange for 40% of the stock of Signet Star and senior and convertible notes. In connection with the formation of Signet Star, North Star Reinsurance entered into a Retrocessional Agreement (the "Retrocessional Agreement") with General Reinsurance Corporation ("GRC"), pursuant to which North Star Reinsurance reinsured its respective liabilities and assigned its respective rights and obligations arising from any insurance or reinsurance contracts written prior to January 1, 1993 with and to GRC.

On December 31, 1995, the Company purchased General Re's interest in Signet Star by issuing to General Re 458,667 shares of Series B Cumulative Redeemable Preferred Stock of the Company having an aggregate liquidation preference of $68,800,000, which was redeemed in 1997. In addition, the Company guaranteed a senior subordinated promissory note of Signet Star which was issued to General Re in exchange for the convertible note which General Re held. As part

20

of this transaction, Signet Star sold to General Re Signet Star Reinsurance Company and renamed Signet Reinsurance Company, Signet Star Reinsurance Company.

In connection with the 1995 acquisition of the remaining 40% interest in Signet Star, North Star Reinsurance was sold to General Re and all business written subsequent to July 1, 1993 was novated to Signet Star. As a result, business written by North Star Reinsurance prior to January 1, 1993, which had been retroceded to General Re, is no longer reflected in the Company's financial statements. The only effect on the Company's financial statements resulting from this aspect of the transaction is that the Company's reserves for losses and loss expenses is reduced by $735,144,000 and "due from reinsurers" is reduced by the same amount. This aspect of the transaction does not effect the Company's cash flow, equity or statements of operations.

(1) Presently leased to a third party.

In addition, the Company and its subsidiaries lease office facilities in various other cities under leases with varying terms and expiration dates.

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. Each 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.

PURPOSE

The purpose of the Annual Incentive Compensation Plan (the "Plan") is to provide incentive compensation to senior executives of W.R. Berkley Corporation (the "Company") in recognition of their significant contributions to the growth, profitability and success of the Company from year to year.

The Company intends that compensation payable under the Plan will constitute "qualified performance-based compensation" under Section 162(m) of the Internal Revenue Code of 1986, as amended. The Plan shall be administratively interpreted and construed in a manner consistent with such intent.

Subject to approval by the Company's stockholders, the Plan is effective as of January 1, 1997.

2.16 Year: The calendar year, which is the fiscal year of the Company.

ARTICLE III

ADMINISTRATION

3.1 The Plan shall be administered by the Committee. For any Year, the Committee shall (i) designate the executives of the Company who shall participate in the Plan, (ii) establish

2

Performance Goals for each Participant and certify the extent of their achievement and (iii) determine each Participant's Target Allocation, Incentive Allocation and Incentive Award.

3.2 Subject to the provisions of the Plan, the Committee shall have full power and authority to (i) interpret the Plan, (ii) adopt rules and regulations relating to the conduct of its business and to the Plan and (iii) make all determinations necessary or advisable for the administration of the Plan. Determinations of the Committee in the administration of the Plan shall be conclusive and binding on the Participants and all other parties concerned.

ARTICLE IV

PARTICIPATION

4.1 Only executives of the Company who, in the Committee's judgment, have contributed, or have the capacity to contribute, in a substantial measure to the successful performance of the Company for a given Year, shall be eligible to participate in the Plan for that Year.

4.2 In selecting Participants for any Year, the Committee shall take into account such factors as the individual's position, experience, knowledge, responsibilities, advancement potential and past and anticipated contribution to Company performance.

ARTICLE V

PERFORMANCE GOALS

5.1 Not later than 90 days after the beginning of any Year, the Committee shall establish Performance Goals for each Participant for that Year.

5.2 Performance Goals established by the Committee for any Year may differ among Participants. The Performance Goals of individual Participants shall be based on criteria in one or more of the following categories, as may be applicable: (i) Earnings per share of common stock, net income and insurance premiums written, (ii) return on common stockholders' equity, (iii) the Company's combined ratio compared to the property and casualty industry combined ratio as calculated by A.M. Best Company and (iv) individual performance, taking into account individual goals and objectives.

5.3 In establishing Performance Goals for any Year, the Committee shall determine, in its discretion, from among the categories specified in Section 5.2, the categories and criteria to be used in measuring each Participant's performance and the percentage allocation for each of the categories and each of the criteria, the sum of which allocations, respectively, shall equal 100 percent. The Committee shall also determine for each Participant for the same Year a threshold level of performance below which no Incentive Award will be payable and a maximum incentive opportunity.

3

ARTICLE VI

TARGET ALLOCATION, INCENTIVE ALLOCATION AND INCENTIVE AWARD

6.1 Not later than 90 days after the beginning of any Year, the Committee shall determine each Participant's Target Allocation for that Year as a percentage of his or her salary for the Year, assuming that the Performance Goals for the Participant are fully met. A Participant's Performance Goals and Target Allocation shall preclude discretion on the part of the Committee to increase the amount payable under the Plan to the Participant to the extent that such discretion would be inconsistent with the requirements for "qualified performance-based compensation" under Section 162(m) of the Code.

6.2 When the Committee has determined the Target Allocation for a Participant for any Year and the performance categories and criteria that establish his or her Performance Goals, it shall communicate this information to the Participant.

6.3 As soon as practicable following verification by the Company's independent public accountants of Earnings for any Year and receipt of information regarding the actual performance of Participants against their respective Performance Goals for the Year, the Committee shall certify (i) the amount, if any, by which Earnings for the Year exceeded the Corporate Threshold for the Year and (ii) the extent to which each Participant achieved his or her Performance Goals for the Year.

6.4 Based on the information certified in accordance with Section 6.3, the Committee shall determine each Participant's Incentive Allocation for the Year by multiplying his or her Target Allocation for the Year by the percentage representing the extent of achievement of his or her Performance Goals for the Year.

6.5 Notwithstanding the provisions of Section 6.4, the Committee may, in its discretion, reduce or eliminate a Participant's Incentive Allocation for any Year based on such objective or subjective criteria as it deems appropriate to take into account circumstances that could not have been anticipated when it established the Participant's Performance Goals for the Year. The amount of a Participant's Incentive Allocation as finally determined by the Committee shall constitute his or her Incentive Award for the Year; provided, however, that no Incentive Award for any Participant for any Year shall exceed 5 percent of Earnings for that Year.

6.6 The Committee shall not be obligated to apply the entire Annual Incentive Pool for any Year to Participants' Incentive Awards. Any amount not so applied shall remain part of the general assets of the Company and shall not be carried over to the Annual Incentive Pool for any subsequent Year.

4

ARTICLE VII

PAYMENT OF INCENTIVE AWARDS

7.1 Except as provided in Section 7.2, a Participant's Incentive Award for any Year shall be paid in a cash lump sum as soon as practicable following the Committee's determination of the amount in accordance with Article VI.

7.2 From time to time, the Committee, in its discretion (under uniform rules applicable to all Participants), may offer Participants the opportunity to defer receipt of all or a portion of the Incentive Award for any Year. Any election to defer shall be made prior to the beginning of the Year except for the first Year that the Plan is in effect. Deferrals shall be in increments of 10 percent of the Participant's Target Allocation for the Year.

Deferred amounts are not forfeitable and shall be paid after termination of employment with the Company. They constitute unfunded general obligations of the Company.

Deferred amounts shall be credited with an interest equivalent amount until the time of final payment at a rate determined by the Committee from time to time. The sum of the amount deferred for any Year plus all interest equivalents shall be paid in a single sum or in up to 15 installments, as specified by the Participant when making the deferral election.

7.3 Each Participant shall designate, in a manner prescribed by the Committee, a beneficiary to receive payments due under the Plan in the event of his or her death. If a Participant dies prior to the date of payment of his or her Incentive Award for any Year or to receipt of all amounts, if any, that were deferred, and if no properly designated beneficiary survives the Participant, the Incentive Award or any other amount due shall be paid to his or her estate or personal representative.

ARTICLE VIII

TERMINATION OF EMPLOYMENT

8.1 If a Participant's employment with the Company terminates by reason of retirement on or after attainment of age 65, death, Disability or Termination Without Cause, or for any other reason specifically approved in advance by the Committee, the Committee shall determine the Participant's Incentive Award as if he or she were employed for the entire Year, and the Participant shall be entitled to receive the Incentive Award prorated to the date of his or her termination of employment.

8.2 If a Participant's employment with the Company terminates for any reason other than as provided in Section 8.1, he or she forfeits any right to receive an Incentive Award for the Year in which the termination occurs.

5

ARTICLE IX

TERMINATION AND AMENDMENT OF THE PLAN

9.1 The Company reserves the right, by action of the Committee, to terminate the Plan at any time. Subject to such earlier termination, the Plan shall have a term of five years from its effective date.

9.2 The Plan may be amended at any time, and from time to time, by a written document adopted by the Committee. No amendment shall be effective prior to approval by the Company's stockholders to the extent that such approval is required by Section 162(m) of the Code or is otherwise required by law.

ARTICLE X

GENERAL PROVISIONS

10.1 Nothing in the Plan shall confer upon any employee a right to continue in the employment of the Company or affect any right of the Company to terminate a Participant's employment.

10.2 A Participant may not alienate, assign, pledge, encumber, transfer, sell or otherwise dispose of any rights or benefits awarded hereunder prior to the actual receipt thereof; and any attempt to alienate, assign, pledge, sell, transfer or assign prior to such receipt, or any levy, attachment, execution or similar process upon any such rights or benefits shall be null and void.

10.3 The Plan shall at all times be entirely unfunded, and no provision shall at any time be made to segregate assets of the Company for payment of any amounts hereunder. No Participant, beneficiary or other person shall have any interest in any particular assets of the Company by reason of the right to receive incentive compensation under the Plan. Participants and beneficiaries shall have only the rights of a general unsecured creditor of the Company.

10.4 The Plan shall be governed by and construed in accordance with the laws of the State of Delaware without reference to principles of conflict of laws.

10.5 The Company shall be authorized to withhold from any award or payment it makes under the Plan to a Participant the amount of withholding taxes due with respect to such award or payment and to take such other action as may be necessary in the opinion of the Company to satisfy all obligations for the payment of such taxes.

10.6 Nothing in the Plan shall prevent the Board from adopting other or additional compensation arrangements, subject to stockholder approval as may be necessary, and such arrangements may be either generally applicable or applicable only in specific cases.

10.7 Participants shall not be required to make any payment or provide any consideration for awards under the Plan other than the rendering of services.

3.3 In the event of any stock split, stock dividend, reclassification, recapitalization or other change that affects the character or amount of outstanding Common Shares and Earnings Per Share, the Committee shall make such adjustments in the number of Units (whether authorized or outstanding and unexercised), the Measuring Price or both as shall, in the sole judgment of the Committee, be equitable and appropriate in order to make the value of such Units, as nearly as may

3

be practicable, equivalent to the value of Units outstanding and unexercised immediately prior to such change. In no event, however, shall any such adjustment give any Participant any additional benefits.

3.4 The Committee shall be precluded from increasing compensation payable under the Plan to a Participant, including acceleration of payment and increase of any amount payable, unless specifically provided for by the Plan.

The last such designation received by the Committee shall be controlling; provided, however, that no designation, or change or revocation thereof, shall be effective unless received by the Committee prior to the Participant's death, and in no event shall it be effective as of a date prior to such receipt. If at the date of a Participant's death, there is no designation of a Beneficiary in effect for the Participant, or if no Beneficiary survives to receive any amount payable under the Plan by reason of the Participant's death, the Participant's estate shall be treated as the Beneficiary for purposes of the Plan.

9.2 A Unit may be exercised only by the Participant to whom it was awarded, except in the event of the Participant's death, when a Unit may be exercised by his or her Beneficiary.

6

Termination Without Cause, or for any other reason specifically approved in advance by the Committee, the term of such Unit shall continue for a period of 14 months from the date of termination (the "Extended Term"). For purposes of this Section 11.1, the Cumulative Unit Value of such Unit shall be determined as of the Valuation Date concurrent with or immediately preceding the end of the Extended Term or any earlier exercise date, whichever is applicable. A Unit whose term is continued for an Extended Term shall be deemed to be automatically exercised as of the last Valuation Date within the Extended Term, unless sooner exercised by the Participant or his or her legal representative.

Management's Discussion and Analysis of
Financial Condition and Results of Operations

INDUSTRY OVERVIEW

The demand for insurance can be characterized as fairly stable and 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. In general, it is believed that the amount of available capacity changes as the perceived rate of return on capital employed fluctuates based on the adequacy of premium rates and available investment returns. 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 the ultimate adequacy of premium rates 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.

OPERATING RESULTS FOR THE YEAR ENDED DECEMBER 31, 1997 AS COMPARED TO THE YEAR ENDED DECEMBER 31, 1996

The Company has adopted SFAS No. 128, which establishes new standards for computing and reporting earnings per share and all income per share amounts have been adjusted to reflect the prescribed changes (see notes to consolidated financial statements). Accordingly, per share results are reported as "basic" and "diluted."

Net income attributable to common stockholders ("Net Income") for 1997 was $91 million, or $3.09 of basic earnings per share, ($3.02 per share diluted), compared with 1996 earnings of $76 million, or $2.56 basic, ($2.53 diluted). The 1997 results include after-tax realized investment gains of $9 million, or $ .29 basic, ($ .28 diluted) compared with $5 million, or $ .16 basic, ($ .16 diluted) for 1996.

Net premiums written in 1997 rose 12% to $1,178 million from $1,053 million written during 1996 due to growth recorded by the regional, specialty, alternative markets, and international operations. Premiums written by the regional operations grew by 19% to $632 million from $531 million written in 1996. The majority of this growth was due to business units which were started during the past several years. Premiums written by the reinsurance segment decreased by 5% to $207 million from $218 million in 1996. This decrease was substantially due to a decrease in treaty business which more than offset premiums generated by the Latin American and Caribbean division that commenced operations in February 1996. Premiums written by the specialty operations grew by 3% to $209 million from $202 million in 1996. This increase was due to an increase in premiums written by the Excess and Surplus operations which more than offset a decline in premiums written by our transportation unit. Premiums written by the alternative markets operations grew by 16% to $88 million from $76 million in 1996. This increase was due primarily to increased market penetration by Signet Star's alternative markets division. Premiums written by the international operations grew by 67% to $42 million from $25 million. This increase was due to the July 1996 start-up of a workers' compensation company in Argentina.

In 1998, the Company expects to start a new operation in the specialty segment as well as a number of units in the Philippines. It is anticipated that the start-up operations will incur operating losses during the first years of operation and that international operations will continue to incur operating losses in 1998. Such losses are not expected to have a material adverse impact on the Company's results of operations.

18

Pre-tax net investment income increased to $200 million from $164 million earned in 1996. This increase was partially due to an increase in average investable assets produced by the issuance of $210 million of capital trust securities issued in December 1996. Excluding the effects of the issuance of these securities, pre-tax net investment income was $193 million, an increase of $29 million over the comparable 1996 amount. This growth was mainly due to an increase in average investable assets produced in cash flow from operations. In addition, an increase in investment income earned in our trading portfolio contributed to the growth in investment income (see "Liquidity and Capital Resources").

Management fees and commissions consist primarily of fees earned by the alternative markets segment. Management fees and commissions increased 3% to $71 million from $69 million in 1996. The increase in management fees and commissions is due primarily to a 1997 acquisition, as intense competition in the workers' compensation market continued to inhibit growth.

Realized investment gains increased to $13 million from $7 million in 1996. 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 1997 and 1996 realized gains resulted from the sale of equity securities.

The consolidated combined ratio (on a statutory basis) of the Company's insurance operations decreased to 101.2% in 1997 from 102.2% in 1996 due to an improvement in the consolidated loss ratio which was partially offset by an increase in the consolidated expense ratio. The consolidated loss ratio (losses and loss expenses incurred expressed as a percentage of premiums earned) decreased to 66.4% from 68.7%. This improvement was primarily due to a decrease in weather related losses incurred by our regional operations and better than expected experience on business written in prior years recorded by our specialty operations.

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 19% to $488 million from $409 million in 1996. 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 (underwriting expenses expressed as a percentage of premiums written) increased to 34.4% for the 1997 period from 33.1% for the comparable 1996 period. This increase resulted primarily from higher commission expenses incurred to generate premium growth.

The increase in interest expense is due to the issuance in December 1996 of $210 million Company-obligated mandatorily redeemable capital securities of a subsidiary trust holding solely junior subordinate debentures (see "Liquidity and Capital Resources").

The Federal income tax provision resulted in an effective tax rate of 24% in 1997 (22% in 1996). The tax rate is lower than the statutory tax rate of 35% because a substantial portion of investment income is tax-exempt. The increase in the effective rate in 1997 is due primarily to the increase in realized gains on investments which are taxed at the full corporate rate.

Preferred dividends decreased as a result of the 1997 repurchase of 276,855 shares of the Series A Preferred Stock, (see "Liquidity and Capital Resources").

OPERATING RESULTS FOR THE YEAR ENDED DECEMBER 31, 1996 AS COMPARED TO THE YEAR ENDED DECEMBER 31, 1995

Net income attributable to common stockholders ("Net Income") for 1996 was $76 million, or $2.56 basic ($2.53 diluted), compared with 1995 earnings of $50 million, or $1.91 basic ($1.90 diluted). The 1996 results include after-tax realized investment gains of $5 million, or $ .16 basic ($ .16 diluted), compared with $6 million, or $ .26 basic ($ .26 diluted) for 1995.

Net premiums written in 1996 grew 22% to $1,053 million from $860 million written during 1995 due to increases recorded by all segments of our operations. Premiums written by the regional operations grew by 13% to $531 million from $471 million written during 1995. Regional net premiums written grew by 16% excluding business assumed from national workers' compensation pools. The majority of this growth was due to new operations which the Company has established during the past five years. Premiums written by the reinsurance operations grew by 11% to $218 million from $196 million written during 1995. The growth in reinsurance premiums written was substantially due to the start-up of a Latin American and Caribbean division and an increase in business written by the Fidelity and Surety division. Premiums written by the specialty operations grew by 26% to $202 million from $161 million. The growth in specialty premiums written is due to an increase in business written by Admiral and Monitor as well as increases in the amount of business retained by Admiral, Monitor and Nautilus. These increases more than offset a decline in premiums written by Carolina Casualty. Premiums written by the alternative markets operations grew by $50 million, to $76 million. This increase is due to the inclusion of results of Midwest Employers Casualty Company ("MECC"), which was acquired in November, 1995. Premiums written by the international segment grew by $19 million to $25 million. The increase in premiums written is due to the inclusion of our primary insurance operations in Argentina, which were acquired in 1995, for a full year and the start up of an Argentine operation in 1996.

Pre-tax net investment income increased to $164 million from $137 million earned in 1995. Approximately three-fourths of this increase was due to the inclusion of the results of MECC. The remainder of this increase was due to the increase in average investable assets generated by cash flow from operations which more than offset the effects of lower yields available in the financial markets (see "Liquidity and Capital Resources").

Management fees and commissions consist primarily of fees earned by the alternative markets segment. Management fees and commissions were basically unchanged for 1996 as market conditions, particularly in workers' compensation insurance, inhibited growth.

Realized gains from the sale of fixed income securities result primarily from the Company's strategy of maintaining an approximate 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 1996 realized gains were from the sale of equity securities.

The consolidated combined ratio (on a statutory basis) of the Company's insurance operations decreased to 102.2% in 1996 from 102.5% in 1995 due to an improvement in the consolidated loss ratio which was partially offset by an increase in the consolidated expense ratio. The consolidated loss ratio (losses and loss expenses incurred expressed as a percentage of premiums earned) decreased to 68.7% from 70.7% primarily due to improved losses at certain specialty companies resulting from a change in the mix of business partially offset by greater catastrophe losses impacting regional operations.

Other operating costs and expenses, which consists of the expenses of the Company's insurance and alternative markets segments as well as the Company's corporate and investment expenses increased by 20% to $409 million from $340 million recorded in 1995. The increase in other operating costs is primarily due to the substantial premium growth volume in all segments of the Company's business, which in turn results in an increase in underwriting expenses. The consolidated expense ratio of the Company's insurance operations

20

(underwriting expenses expressed as a percentage of premiums written) increased to 33.1% for the 1996 period from 31.3% for the comparable 1995 period. This increase resulted from the higher commission expenses incurred to generate premium growth.

Interest expense increased due to the January 1996 issuance of $100 million of long-term debt. In addition, in December 1996, the Company issued $210 million of Company-obligated mandatorily redeemable capital securities of a subsidiary trust holding solely junior subordinated debentures (see "Liquidity and Capital Resources").

The Federal income tax provision resulted in an effective tax rate of 22% in 1996 and 21% in 1995. The tax rate is lower than the statutory tax rate of 35% because a substantial portion of investment income is tax-exempt. The increase in the effective tax rate in 1996 is due primarily to a decrease in the percentage of pre-tax income that is tax-exempt.

In December 1995, the Company purchased all the remaining outstanding common stock of Signet Star Holdings. As a result of this acquisition, the minority interest in 1996 was solely related to international operations.

Preferred dividends increased as a result of the December 1995 issuance of Series B Cumulative Redeemable Preferred Stock (see "Liquidity and Capital Resources").

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 $229 million in 1997, $244 million in 1996 and $207 million in 1995.

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. 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 3 of "Notes to Consolidated Financial Statements").

FINANCING ACTIVITY In October 1995, the Company issued 5,175,000 shares of common stock, par value $.20 per share and received net proceeds of approximately $145 million which was used to finance the acquisition of MECC.

On December 31, 1995, in connection with the acquisition of the remaining 40% of Signet Star, the Company issued to General Reinsurance Corporation ("General Re"), 458,667 shares of Series B Cumulative Redeemable Preferred Stock having an aggregate liquidation preference of $68,800,000. In addition, the Company guaranteed a senior subordinated promissory note of Signet Star in the principal amount of $35,793,085, which matures July 1, 2003 and bears interest at the rate of 6.5%. This note was issued to General Re in exchange for the convertible note previously held by General Re. In November 1993, Signet Star borrowed the maximum amount available under its revolving credit facility and used the proceeds to redeem senior notes issued in connection with the July 1, 1993 acquisition. The revolving credit facility was repaid on January 19, 1996 as discussed below.

On January 19, 1996, the Company issued $100 million of 6.25%, ten-year notes which are not redeemable until maturity and utilized a portion of the proceeds to retire $28.4 million of Signet Star's bank debt. In addition, a portion of the proceeds were used to retire $28 million of Series B Preferred Stock.

On December 19, 1996, the Company issued $210 million of Company-obligated manditorily redeemable capital securities of a subsidiary trust holding solely junior subordinated debentures of the Corporation due December 15, 2045 ("Capital Trust Securities") and utilized $38.4 million of the proceeds to retire the remaining outstanding shares of the Series B Preferred Stock. In addition, during December 1996 and January 1997, the Company utilized $39.2 million of the proceeds to retire 252,273

W. R. BERKLEY CORPORATION AND SUBSIDIARIES

21

shares of the Series A Preferred Stock and placed $115.8 million in a trust which will be used to service the remaining outstanding Series A Preferred Stock. In the second and third quarters of 1997, 93,775 shares of the Series A Preferred Stock were purchased by subsidiaries of the Company. The Company expects that the balance of the proceeds of the trust will be utilized to redeem the Series A Preferred Stock on January 25, 1999. The balance of the proceeds is available for acquisitions, working capital and other general corporate purposes.

In March 1995, the Company purchased 175,500 shares of Common Stock for approximately $4.1 million. During 1996, the Company purchased 862,500 shares of Common Stock for approximately $24.2 million. On November 11, 1997, the Board of Directors authorized the Company to repurchase up to 2,000,000 shares of Common Stock.

The Company has on file two "shelf" Registration Statements with the Securities and Exchange Commission with a combined remaining balance of $190 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. In addition, the Company has a $50 million line-of-credit available.

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, valued on a cost basis, grew in 1997 by $282 million to approximately $3,218 million primarily due to the combined effects of net cash flow from operations and the financing activities discussed above.

During 1997, the Company invested approximately $243 million of its available cash inflow in invested cash and fixed income securities. At December 31, 1997, the portion of the portfolio invested in tax-exempt securities was 32% (30% in 1996); U.S. Government securities and cash equivalents remained at 26%; mortgage-backed securities were 16% (18% in 1996); corporate fixed maturity securities remained at 14%; trading account securities remained at 9%; and other equity securities represented the balance.

FEDERAL INCOME TAXES The Company files a consolidated Federal income tax return. At December 1997, the Company had a deferred tax liability of $79 million, which primarily relates to unrealized investment gains and intangible assets, and a deferred tax asset of $47 million, which primarily relates to the discounting of loss reserves for Federal income tax purposes.

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.

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 1997, all regional subsidiaries generally retained $300,000 on individual property casualty risks. Acadia Insurance Company retained up to $1.3 million per bond for surety business. Other regional companies writing surety business retained up

22

to $450,000 ($325,000 prior to October 1, 1997). The regional group also maintained catastrophe reinsurance protection for approximately 95% of weather-related losses above $6 million per occurrence up to a maximum of $34 million. In addition, certain of the regional operating units carried additional aggregate catastrophe protection of $13.5 million in excess of $4 million for storms exceeding $500,000; $5 million in excess of $6.5 million for storms exceeding $1.0 million; and $4.5 million in excess of $7 million for storms exceeding $1.5 million.

REINSURANCE OPERATIONS Signet Star's catastrophe retrocession program provides coverage for property losses in four layers as follows: (i) 100% of $7.5 million in excess of $6.0 million per occurrence; (ii) 95% of $7.5 million in excess of $13.5 million per occurrence; and (iii) 95% of $9.0 million in excess of $21.0 million per occurrence, and 100% of $15 million in excess of $30 million, (for California only and only under certain conditions). In 1997, Signet Star has 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 $4.7 million in excess of $300,000. These coverages apply to Signet Star's individual certificate and master certificate business. During 1997, 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 79.5% of each loss up to $2.5 million in excess of $3.25 million per occurrence for its fidelity and surety business. During 1997, the Latin American and Carribean division retained $250,000 for property business and $500,000 for Marine, Energy and Aviation business.

SPECIALTY OPERATIONS Admiral's retention in 1997 was $175,000 per risk for most classes of business and $5.0 million, per insured, for business written by Monitor Liability Managers. In addition, in 1997 Admiral's Directors' and Officers' coverage also included additional protection on an aggregate basis. Nautilus generally retained $140,000 per risk in 1997 and Carolina maintained its retention at $300,000 on property and liability exposures. In 1997, Carolina Casualty (on business underwritten by Monitor Surety Managers), retained up to $1.5 million on a per principal per bond basis. Great Divide retained $120,000 per risk in 1997 ($187,500 in 1998). The Specialty Group (except Carolina) is also covered under the regional group's property catastrophe protection for 95% of $34 million in excess of $6 million.

ALTERNATIVE MARKETS OPERATIONS Midwest's retention is generally $1 million per occurrence above the self insured's underlying retention.

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

YEAR 2000

The Company continues to address system programming issues with regards to system requirements for the year 2000. Costs associated with the year 2000 projects, which to date have not been significant, are expensed as incurred. The Company has examined the year 2000 issues and does not expect it to have a material impact on the Company's operations. With respect to year 2000 claims exposure for our insurance and reinsurance subsidiaries, to date, no significant losses have arisen. However, due to the potential for judicial decisions which re-formulate policies to expand their coverage to previously unforeseen theories of liabilities which may produce unanticipated claims, at this point in time, the estimation of any potential year 2000 liabilities is not determinable.

CAPITALIZATION

For the year ended December 31, 1997, Stockholders' equity increased by approximately $68 million. The increase in stockholders' equity is attributable to an increase in retained earnings and an increase in unrealized gains in marketable securities which was partially offset by the repurchase of the Series A Preferred stock discussed above. Accordingly, the Company's total capitalization increased to $1,546 million at December 31, 1997 and the percentage of the Company's capital attributable to long-term debt decreased to 25% at December 31, 1997 from 26% at December 31, 1996.

W. R. BERKLEY CORPORATION AND SUBSIDIARIES

NOTES TO CONSOLIDATED FINANCIAL STATEMENTS
For the years ended December 31, 1997, 1996, and 1995

(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"). 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. All significant intercompany transactions and balances have been eliminated. Reclassifications have been made in the 1996 and 1995 financial statements to conform them to the presentation of the 1997 financial statements.

(B) Revenue recognition

Insurance premiums written are recognized as earned generally on a pro-rata basis over the contract period. Management fees on insurance services 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 a separate component of stockholders' equity.

Short sales and short call options used in trading account activities, as part of a hedging strategy, are included in other liabilities. Short sales and short call options are reported at fair value, with unrealized gains and losses reflected in net investment income.

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 are 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) Per Share Data

All share data have been retroactively adjusted to reflect a three-for-two stock split which was affected in 1997. The Company implemented Statement of Financial Accounting Standards Number 128 in 1997. All prior period amounts have been restated. 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 from shareholders are not considered to be outstanding for the purposes of calculating per share amounts and, accordingly, have been excluded from stockholders' equity.

(E) 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.

(F) 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 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.

One subsidiary of the Company, Midwest Employers Casualty Company
("Midwest"), discounts its liabilities for excess workers' compensation ("EWC")
losses and loss expenses using a "risk-free" rate. Midwest discounts its EWC liabilities 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 excess workers' compensation line of business (see Note 10 of notes to consolidated financial statements).

28

(G) 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 liability must be discharged by the Company. 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.

(H) 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 $2,950,000, $3,334,000 and $2,465,000 for 1997, 1996 and 1995, respectively.

(I) Federal income taxes

The Company files a consolidated Federal income tax return. In 1995 and prior years, Signet Star Holdings, Inc. filed its own consolidated Federal income tax return.

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.

(J) 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.

(K) 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. Gains or losses (losses of $1,711,000 in 1997) resulting from translating foreign currency financial statements are reported as a component of stockholders' equity. Gains or losses (gains of $1,408,000 in 1997) resulting from foreign currency transactions (transactions denominated in a currency other than the entity's functional currency) are included in other income in the statement of operations.

(L) 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. Included in the statement of operations is depreciation expense of $12,799,000, $12,234,000 and $10,133,000 for 1997, 1996 and 1995, respectively.

(M) Segment Disclosure

In June 1997, the FASB issued SFAS 131 "Disclosures About Segments of an Enterprise and Related Information." SFAS 131 redefines how operating segments are determined and requires disclosure of certain financial and descriptive information about a company's operating segments. The Company adopted provisions of this statement in 1997 and all prior periods have been restated. This statement relates to presentation of information and had no impact on the Company's results of operations or financial condition.

(N) Recent accounting pronouncements

The American Institute of Certified Public Accountants issued Statement of Position 97-3 "Accounting by Insurance and Other Enterprises for Insurance-Related Assessments," which will be effective for fiscal periods beginning in 1999. SOP 97-3 provides guidance on accounting and disclosure of insurance related assessments. The Company does not expect this statement to have a material impact on the Company's financial position or results of operation.

In June 1997, the FASB issued SFAS 130, "Reporting Comprehensive Income," which requires enterprises to disclose comprehensive income and its components in a prominent position on the face of the financial statements. The Company will implement this statement in 1998. This statement relates to presentation of information and will have no impact on the Company's results of operations or financial condition.

(2) 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. Due from reinsurer has been reduced by an offsetting funds held balance. The following amounts arising under reinsurance ceded contracts have been deducted in arriving at the amounts reflected in the statement of operations:

(Dollars in thousands)          1997       1996        1995
                            --------   --------    --------
Premiums written            $240,754   $210,009    $212,169
                            --------   --------    --------
Premiums earned             $239,233   $216,127    $207,375
                            --------   --------    --------
Losses and loss expenses    $129,405   $120,784    $134,120
                            --------   --------    --------

(3) 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 1998, the maximum amount of dividends which can be paid without such approval is approximately $98,713,000.

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

(Dollars in thousands)          1997       1996        1995
                            --------   --------    --------
Net income                 $ 121,300   $ 84,249    $ 75,587
                            --------   --------    --------
Policyholders' surplus     $ 971,749   $881,380    $839,890
                            --------   --------    --------

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, loss reserves and unearned premiums are reflected net of applicable reinsurance and certain assets designated as "non admitted assets" are charged directly to surplus.

At December 31, 1997 and 1996, bonds with a fair value of $160,369,000 and $139,497,000 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.

(4) ACQUISITIONS

During 1997 and 1996, several acquisitions were completed for an aggregate consideration of approximately $7,238,000 and $15,955,000, respectively. The acquisitions were accounted for as purchases and, accordingly, the results of operations of the acquired 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 1997 and 1996 were as follows:
Investments in fixed maturity and equity securities of $2,192,000 and $6,434,000; cash and invested cash of $7,823,000 and $4,216,000; excess of cost over net assets acquired of $2,688,000 and $7,138,000; and other liabilities, net of other assets of $5,465,000 and $1,833,000.

During 1995, the Company purchased majority interests in two property and casualty companies in Argentina for consideration of approximately $9.2 million, which constituted a portion of the Company's initial contribution to Berkley International, LLC.

The proforma effect of these transactions on the Company's results of operations is not significant.

On November 8, 1995, the Company acquired 100% of the stock of MECC, Inc., the Parent of Midwest Employers Casualty Company, for $141,908,000. In connection with this acquisition, the Company also retired approximately $19,590,000 of MECC, Inc.'s debt. The purchase was funded by the issuance of 5,175,000 shares of Common Stock issued at $29.17 per share. On December 31, 1995, the Company acquired General Re Corporation's ("General Re") 40% interest in Signet Star Holdings, Inc. ("Signet Star") by issuing to General Re 458,667 shares of Series B Cumulative Redeemable Preferred Stock of the Company having an aggregate liquidation preference of $68,800,000. During 1996 the Company purchased all outstanding shares of the Series B Preferred Stock for $66 million. The only significant effect on the Company's financial statements from this acquisition was an increase in preferred stock outstanding and the elimination of the related minority interest because Signet Star's results of operations were previously consolidated.

All of the acquisitions were accounted for as purchases and, accordingly, the results of operations of the acquired companies have been included from the dates of acquisition.

The Company's consolidated Proforma results of operations assuming the acquisitions of MECC, Inc. and the remaining 40% interest in Signet Star occurred as of January 1, 1995 are as follows:

(Dollars in thousands, except per share data)           1995

                                                  ----------

The Proforma consolidated financial data do not purport to represent what the Company's results of operations actually would have been had the acquisitions and related financings occurred on the dates indicated, or to project the Company's results of operations for any future period. The above amounts primarily reflect the effects on results of operations of certain adjustments resulting from the revaluation of assets and liabilities of the purchased companies and from the financing of such acquisitions.

(5) FEDERAL INCOME TAXES

Federal income tax expense consists of:

Federal income tax expense applicable to realized investment gains was $4,615,000, $2,603,000 and $3,664,000 in 1997, 1996 and 1995, respectively. The Company had a current tax receivable of $5,869,000 at December 31, 1997 and a current income tax payable of $6,224,000 at December 31, 1996. The Company's tax returns through December 31, 1991 have been examined by the Internal Revenue Service and additional income taxes have been paid.

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 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 parity with all other outstanding indebtedness of the Company.

The Company has on file two "shelf" registration statements with the Securities and Exchange Commission with a combined remaining balance of $190 million in additional equity and/or debt securities. The securities may be offered from time-to-time as determined by funding requirements at market conditions. In addition, the Company has a $50 million line-of-credit available.

(7) STOCK OPTION PLAN

The Company adopted the W. R. Berkley Corporation 1992 Stock Option Plan ("the Stock Option Plan") under which 2,625,000 shares of Common Stock were reserved for issuance. In May 1997, the Corporation restated the Stock Option Plan to increase the number of shares of Common Stock authorized for issuance under the Stock Option Plan from 2,625,000 to 7,125,000. Pursuant to the Plan, options may be granted at prices determined by the Board of Directors but not less than fair market value on the date of grant. To date, options have been granted with an exercise price equal to the average of the high and low market price on the date of grant.

The following table summarizes option information, including options granted under both the 1992 and prior plans:

(a) During 1997, 1996 and 1995, gross gains of $7,988,000, $5,904,000 and $11,570,000, respectively, and gross losses of $11,296,000, $4,054,000 and $3,751,000, respectively, were realized. Included in fixed maturity securities sold are losses arising from the Company's investments in a municipal security trading partnership. The primary focus of the partnership is municipal arbitrage. Municipal arbitrage is an investment strategy which attempts to capitalize on certain anomalies which tend to occur in the municipal bond market.

(b) The provision for decline in value of investments is $2,800,000, $3,485,000 and $3,333,000 as of December 31, 1997, 1996 and 1995, respectively.

(a) The primary focus of the trading account is merger and municipal fixed income 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 also incur losses during market declines, hedge positions may incur losses during market advances. As of December 31, 1997, the notional amount of option and swap contracts outstanding are $32,524,000 and $10,000,000, respectively.

Investment income earned from trading account activity includes unrealized trading gains of $10,833,000, $2,013,000, and $352,000 for 1997, 1996 and 1995, respectively. Included in other liabilities at their fair value are short sales and short call options $159,456,000 and $87,080,000 as of December 31, 1997 and 1996, respectively. The corresponding proceeds of the short securities are $162,360,000 and $83,172,000 as of December 31, 1997 and 1996, respectively.

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 excess workers' compensation 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 excess workers' compensation 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 average discount rate for accident years 1997, 1996 and 1995 and prior is 5.98%, 5.90% and 5.80%, respectively. The aggregate net discount, after reflecting the effects of ceded reinsurance, is $189,600,000, $172,415,000 and $152,235,000 at December 31, 1997, 1996 and 1995, 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 our 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 $33.1 million and $35.2 million at December 31, 1997 and 1996, respectively. The Company's gross reserves for losses and loss adjustment expenses relating to pollution and environmental claims were $68.4 million and $71.9 million at December 31, 1997 and 1996, respectively. Net incurred losses and loss expenses for reported pollution and environmental claims were approximately $ .1 million, $6.9 million and $8.0 million in 1997, 1996 and 1995, respectively. Net paid losses and loss expenses has averaged approximately $3 million for each of the last three years. The estimation of these liabilities is subject to significantly

36

greater than normal variation and uncertainty because of the difficulty of making 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 is highly uncertain.

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 number of shares used in the computation of basic earnings per share was 29,503,000, 29,792,000 and 26,121,000 for 1997, 1996 and 1995, respectively. The number of shares used in the computations of diluted earnings per share was 30,185,000, 30,130,000 and 26,262,000 for 1997, 1996 and 1995, respectively. The difference in calculating basic and diluted earnings per share is attributable entirely to the dilutive effect of stock based employee compensation plans.

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

The accounting policies of the segments are the same as those described in the summary of significant accounting policies. Summary financial information about the Company's operating segments is presented in the following table. Income before income taxes by segment consists of revenues less expenses related to the respective segment's operations. These amounts include realized gains (losses) where applicable. Intersegment revenues consist primarily of dividends, interest on intercompany debt and fees paid by subsidiaries for portfolio management and other services to the Company. Identifiable assets by segment are those assets used in the operation of each segment.

(16) 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 $8,402,000, $7,370,000 and $6,344,000 for 1997, 1996 and 1995, 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 Committee of the Board of Directors. Key employees are awarded participation units ("units") as determined by the Compensation and Stock Option Committee of the Board of Directors. 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.

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, 1997 and 1996, and the related consolidated statements of operations, stockholders' equity and cash flows for each of the years in the three-year period ended December 31, 1997. These consolidated financial statements are the responsibility of the Company's management. Our responsibility is to express an opinion on these consolidated financial statements based on our audits.

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

In our opinion, the consolidated financial statements referred to above present fairly, in all material respects, the financial position of W. R. Berkley Corporation and subsidiaries at December 31, 1997 and 1996, and the results of their operations and their cash flows for each of the years in the three-year period ended December 31, 1997, in conformity with generally accepted accounting principles.
