                                PROXY STATEMENT
                         ------------------------------

                         ANNUAL MEETING OF STOCKHOLDERS
                                  MAY 11, 2004

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

                     SOLICITATION AND REVOCATION OF PROXIES

     The enclosed proxy is solicited by the Board of Directors of W. R. Berkley
Corporation (the "Company") for use at the Annual Meeting of Stockholders to be
held at the executive offices of the Company, 475 Steamboat Road, Greenwich,
Connecticut, on Tuesday, May 11, 2004 at 1:30 p.m. and at any adjournment
thereof.

     The giving of a proxy does not preclude a stockholder from voting in person
at the Annual Meeting. The proxy is revocable before its exercise by delivering
either written notice of such revocation or a later dated proxy to the Secretary
of the Company at its executive offices at any time prior to voting of the
shares represented by the earlier proxy. In addition, stockholders attending the
Annual Meeting may revoke their proxies by voting at the Annual Meeting.

     The expense of preparing, printing and mailing this proxy statement will be
paid by the Company. The Company has engaged Georgeson Shareholder
Communications, Inc. to assist in the solicitation of proxies from stockholders
for a fee estimated at $6,500. In addition to the use of the mails, proxies may
be solicited personally or by telephone by regular employees of the Company
without additional compensation, as well as by Georgeson employees. The Company
will reimburse banks, brokers and other custodians, nominees and fiduciaries for
their direct costs in sending the proxy materials to the beneficial owners of
the Company's common stock.

     The Annual Report of the Company for the fiscal year ended December 31,
2003 is being mailed to all stockholders with this proxy statement. The
approximate mailing date is April 12, 2004.

     A list of stockholders will be available for inspection during business
hours for at least ten days prior to the Annual Meeting at the executive offices
of the Company at 475 Steamboat Road, Greenwich, Connecticut 06830.

     The matters to be acted upon are described in this proxy statement. Proxies
will be voted at the Annual Meeting, or at any adjournment thereof, at which a
quorum is present, in accordance with the directions on the proxy. Votes cast by
proxy or in person at the Annual Meeting will be tabulated by election
inspectors appointed for the Annual Meeting. The election inspectors will also
determine whether a quorum is present. The holders of a majority of the common
stock outstanding and entitled to vote who are present either in person or
represented by proxy constitute a quorum for the Annual Meeting. The election
inspectors will treat abstentions and "broker non-votes" as shares that are
present and entitled to vote for purposes of determining the presence of a
quorum, but as unvoted for purposes of determining the approval of any matter
submitted. A "broker non-vote" is when a broker indicates on a proxy that it
does not have discretionary authority as to certain shares to vote on a
particular matter and has not received instructions from the beneficial owner
with respect to that matter.

                                        1


                      OUTSTANDING STOCK AND VOTING RIGHTS

     Only stockholders of record at the close of business on March 19, 2004 are
entitled to receive notice of and to vote at the Annual Meeting. The number of
shares of voting stock of the Company outstanding and entitled to vote on that
date was 83,784,577 shares of common stock. Each such share of common stock is
entitled to one vote. At March 19, 2004, executive officers and directors of the
Company owned or controlled approximately 15.0% of the outstanding common stock.
Information as to persons beneficially owning 5% or more of the common stock may
be found under the heading "Principal Stockholders" below.

     Unless otherwise directed in the proxy, the persons named therein will vote
"FOR" the election of the director nominees listed below, "FOR" the approval of
the W. R. Berkley Corporation 2004 Long-Term Incentive Plan, "FOR" the approval
of the amendment to the Company's Restated Certificate of Incorporation to
increase the number of authorized shares of common stock from 150,000,000 to
300,000,000 and "FOR" the ratification of the appointment of KPMG LLP as the
Company's independent certified public accountants for its fiscal year ending
December 31, 2004. If a returned proxy does not specify a vote for or against a
proposal, it will be voted in favor thereof.

     The election of directors, the approval of the W. R. Berkley Corporation
2004 Long-Term Incentive Plan and the ratification of the appointment of KPMG
LLP require the affirmative vote of a majority of the shares present at the
meeting to constitute the action of the stockholders. The approval of the
amendment to the Company's Restated Certificate of Incorporation requires the
affirmative vote of a majority of the shares of common stock outstanding and
entitled to vote at the Annual Meeting.

     As of the date hereof, the Board of Directors knows of no other business
that will be presented for consideration at the Annual Meeting. If other
business shall properly come before the Annual Meeting, the persons named in the
proxy will vote according to their best judgment.

                             ELECTION OF DIRECTORS

     As permitted by Delaware law, the Board of Directors is divided into three
classes, the classes being divided as equally as possible and each class having
a term of three years. Each year the term of office of one class expires. This
year the term of a class consisting of three directors expires. It is the
intention of the Board that the shares represented by proxy, unless otherwise
indicated therein, will be voted for the election of William R. Berkley, Jr.,
Ronald E. Blaylock and Mark E. Brockbank as directors to hold office for a term
of three years until the Annual Meeting of Stockholders in 2007 and until their
respective successors are duly elected and qualified. In addition, it is the
intention of the Board that the shares represented by proxy, unless otherwise
indicated thereon, will be voted for the election of Rodney A. Hawes, Jr. to
hold office for a term of one year until the Annual Meeting of Stockholders in
2005 and until his successor is duly elected and qualified.

     The persons designated as proxies reserve full discretion to cast votes for
other persons in the event any such nominee is unable to serve. However, the
Board has no reason to believe that any nominee will be unable to serve if
elected. The proxies cannot be voted for a greater number of persons than the
four named nominees.

                                        2


     THE BOARD OF DIRECTORS UNANIMOUSLY RECOMMENDS A VOTE "FOR" EACH OF THE
NOMINEES FOR DIRECTOR.

     The following table sets forth information regarding each nominee and the
remaining directors who will continue in office after the Annual Meeting.

                     CORPORATE GOVERNANCE AND BOARD MATTERS

     Our Board of Directors is committed to sound and effective corporate
governance practices. Accordingly, our Board has adopted written Corporate
Governance Guidelines, which address, among other things, (1) director
qualification standards, (2) director responsibilities, (3) director access to
management and, as necessary and appropriate, independent advisors, (4) director
compensation, (5) director orientation and continuing education, (6) management
succession, and (7) annual performance evaluation of the Board.

     The Board of Directors has standing committees including: the Audit
Committee, Compensation and Stock Option Committee, and Nominating and Corporate
Governance Committee. Each of these committees has a written charter. Our
Corporate Governance Guidelines and the charters for each of these standing
committees are available for review on our website at www.wrberkley.com, and the
Audit Committee charter is also attached as Annex A hereto.

     The Board is currently composed of nine directors, all of whom, other than
Messrs. William R. Berkley, William R. Berkley, Jr. and Jack H. Nusbaum, have
been determined by the Board to be independent in accordance with applicable New
York Stock Exchange rules. At this Annual Meeting, the Board is being expanded
to ten directors through the proposed addition of an additional independent
director.

     The Board held five meetings during 2003. No director attended fewer than
75% of the total number of meetings of the Board and all committees on which he
served. The Company encourages its directors to attend its Annual Meeting of
Stockholders, and at last years' meeting at least two directors were in
attendance.

     BOARD COMMITTEES

     AUDIT COMMITTEE.  The Audit Committee is appointed by the Board to assist
the Board in monitoring (1) the integrity of the financial statements of the
Company, (2) the independent auditors' qualifications and independence, (3) the
performance of the Company's internal audit function and independent auditors,
and (4) compliance by the Company with legal and regulatory requirements. The
Audit Committee has also adopted procedures to receive, retain and treat any
good faith complaints received regarding accounting, internal accounting
controls or auditing matters and provide for the anonymous, confidential
submission of concerns regarding these matters.

     The Audit Committee is currently composed of Messrs. Shapiro, Blaylock and
Ablove, all of whom are independent under the rules of the SEC and the New York
Stock Exchange. Mr. Shapiro is the current Chair of the committee. The Board has
identified Mr. Shapiro as a current member of our Audit Committee who meets the
definition of an "audit committee financial expert" recently established by the
SEC. During fiscal 2003, the Audit Committee held seven meetings.

     The Audit Committee has determined to engage KPMG LLP as independent
auditors for fiscal year 2004 and is recommending that our stockholders ratify
this appointment at our annual meeting. The report of our Audit Committee is
found on page 25 of this proxy statement.

     COMPENSATION AND STOCK OPTION COMMITTEE.  The Compensation and Stock Option
Committee has overall responsibility for discharging the Board's
responsibilities relating to the compensation of the Company's senior executive

of the New York Stock Exchange. Mr. Merrill is the current Chair of the

report of our Compensation and Stock Option Committee on executive compensation
is found on page 12 of this proxy statement.

     NOMINATING AND CORPORATE GOVERNANCE COMMITTEE.  The Nominating and
Corporate Governance Committee was formed in 2004 to assist the Board in (1)
identifying individuals qualified to become members of the Board (consistent
with criteria to be approved by the Board), (2) recommending that the Board
select the director nominees for the next annual meeting of stockholders or for
other vacancies on the Board, (3) overseeing the evaluation of the Board and
management, (4) reviewing the corporate governance guidelines and the corporate
code of ethics and (5) generally advising the Board on corporate governance and
related matters. Our Corporate Governance Guidelines address director
qualification standards.

     The Nominating and Corporate Governance Committee will consider qualified
director nominees recommended by stockholders. Nominations for consideration by
the Nominating and Corporate Governance Committee, together with a description
of his or her qualifications and other relevant information, should be sent to
the attention of the General Counsel, c/o W. R. Berkley Corporation, 475
Steamboat Road, Greenwich, Connecticut 06830. Stockholders may also follow the
nomination procedures described under "Stockholder Nominations for Board

     The Nominating and Corporate Governance Committee is currently composed of
Messrs. Ablove, Blaylock, Brockbank, Daly, Merrill and Shapiro, all of whom are
considered independent under the rules of the New York Stock Exchange.

     OTHER COMMITTEES.  During 2003, the Board had three standing committees in
addition to the committees set forth above: the Executive Committee, the Pricing
Committee and the Business Ethics Committee.

     The Executive Committee is authorized to act on behalf of the Board during
periods between Board meetings. The Committee is composed of Messrs. William R.
Berkley and Nusbaum. During 2003, the Committee took action by unanimous written
consent on one occasion.

     The Pricing Committee, which during 2003 was composed of Messrs. William R.
Berkley and Nusbaum, acts in the event of certain offerings of the Company's
securities with respect to such matters as determining the price and terms at
which such securities shall be sold to underwriters and the public. During 2003,
the Committee held two meetings.

     The Business Ethics Committee, which during 2003 was composed of Messrs.
Blaylock, Nusbaum and Shapiro, administers the Company-wide business ethics
program. The Committee reviews disclosures made by Company employees under the
Company's Statement of Business Ethics, determines if any issue presented raises
an ethics concern and takes any appropriate action. During 2003, the Committee
held one meeting.

                                        7


     CODE OF ETHICS

     We have had a Statement of Business Ethics in place for many years. This
code, which applies to all of our employees, is a statement of our high
standards for ethical behavior and legal compliance, and governs the manner in
which we conduct our business. This Statement of Business Ethics covers all
areas of professional conduct, including employment policies, conflicts of
interest, intellectual property and the protection of confidential information,
as well as adherence to the laws and regulations applicable to the conduct of
our business.

     In 2004, we adopted a Code of Ethics for Senior Financial Officers. This
Code of Ethics, which applies to our chief executive officer, chief financial
officer and controller, addresses the ethical handling of conflicts of interest,
the accuracy and timeliness of SEC disclosure and other public communications
and compliance with law.

     A copy of our Statement of Business Ethics and Code of Ethics for Senior
Financial Officers can be found on our website at www.wrberkley.com. We intend
to disclose any amendments to these procedures, and waivers of these policies
for executive officers and directors, on our website.

     COMMUNICATIONS WITH NON-MANAGEMENT DIRECTORS; EXECUTIVE SESSIONS

     A stockholder who has an interest in communicating with management or
non-management members of the Board of Directors may do so by directing the
communication to the General Counsel. Information about the Company, including
with respect to its corporate governance policies and copies of its SEC filings,
is available on our website at www.wrberkley.com. Our filings with the SEC are
also available at the SEC's website at www.sec.gov. Persons who desire to
communicate with the non-management directors should send their correspondence
addressed to the attention of the General Counsel, c/o W. R. Berkley
Corporation, 475 Steamboat Road, Greenwich, Connecticut 06830. The General
Counsel will provide a summary of all appropriate communications to the
addressed non-management directors and will provide a complete copy of such
communications upon the request of the addressed director.

     In accordance with applicable New York Stock Exchange Rules, the
non-management directors will meet regularly in executive session, with an
additional meeting of independent directors only to be held annually.

                             DIRECTOR COMPENSATION

     For 2003, each director received a quarterly retainer of $6,000 and a fee
of $1,500 for each Board meeting attended. In addition, on May 20, 2003,
pursuant to the Company's 1997 Directors Stock Plan, each continuing director
received 237 shares of common stock (adjusted for the 3-for-2 stock split
effected in August 2003). The number of shares to be granted to each director
under such Plan for each year is determined by dividing $7,500 by the closing
price of the common stock on the trading day preceding the date of the Annual
Meeting of Stockholders for the year in which the grant is made. For 2003, the
annual retainer, the fees and the fair market value of such shares of common
stock on the date of grant are included under "Executive Compensation" in the
Summary Compensation Table for William R. Berkley. These shares of common stock
are also included in the tables under "Principal Stockholders." Members of the
Audit Committee and the Compensation and Stock Option Committee, which are both
comprised solely of directors that are independent under the rules of the New
York
                                        8


Stock Exchange, each receive an annual stipend of $5,000, with their respective
Chairmen each receiving an additional $5,000 annual stipend. Members of the

                    TRANSACTIONS WITH MANAGEMENT AND OTHERS

     During 2003, the Company engaged in certain transactions with Interlaken
Capital, Inc., a company substantially owned and controlled by William R.
Berkley, the Company's Chairman of the Board and Chief Executive Officer. The
Company paid Interlaken $150,000 for services provided by certain employees of
Interlaken in connection with the review of certain private equity transactions.
Interlaken was reimbursed by the Company on a time and expense basis. Interlaken
paid rent in the amount of $22,119 to the Company for separate office space on
the Company's premises. Certain of the Company's employees perform services for
Interlaken as well for which Interlaken compensates them separately.

     During 2001, certain subsidiaries of the Company invested an aggregate of
$5,000,000 in unsecured promissory notes of The First Marblehead Corporation, a
company of which William R. Berkley is a director and in which William R.
Berkley and William R. Berkley, Jr. have, directly or indirectly, minority
equity interests. The notes were scheduled to mature in 2004 and to bear base
interest at a minimum rate of 10% per annum and bonus interest at the rate of
15% per annum. During 2003, the outstanding principal balance of the notes and
all base and bonus interest thereon were pre-paid. The Company's effective rate
of return on its investment in the notes was in excess of 24% per annum.

     Jack H. Nusbaum, a director of the Company, is Chairman of Willkie Farr &
Gallagher LLP, outside counsel to the Company.

                    COMPENSATION AND STOCK OPTION COMMITTEE
                        REPORT ON EXECUTIVE COMPENSATION

     The Compensation and Stock Option Committee (the "Committee") is comprised
entirely of independent, non-management directors. The Committee has overall
responsibility for discharging the Board of Director's responsibility relating
to compensation of the Chief Executive Officer ("CEO"), other senior executive
officers and directors.

     COMPENSATION PHILOSOPHY.  The Compensation and Stock Option Committee
follows a compensation philosophy under which the principal determinants of
compensation are both the current and long-term financial performance of the
Company, together with achievement of non-financial corporate objectives and
individual performance. The Company's performance is reviewed by the Committee
in both absolute terms and relative to the performance of the property and
casualty insurance industry as a whole. The Committee believes that this
approach provides incentives to the CEO and other management personnel to focus
on meeting key corporate strategic objectives, such as enhancing returns and
driving profitable growth while recognizing individual achievements. Focusing on
these key objectives should in turn enhance stockholder value. The Committee
also believes that it continues to be important to use compensation to attract
and reward executives who contribute to the Company's long-term success by
demonstrated, sustained performance.

     To this end, the Company relies on salary, annual cash incentive awards,
equity-based compensation through the 2003 Stock Incentive Plan and long-term
cash incentives through the Long-Term Incentive Compensation Plan ("LTIP"). The
Company has not entered into employment agreements with any of its officers.

     For 2003, the Committee retained The Ross Companies ("Ross") to provide
advice with respect to executive compensation. Ross advised the Committee with
respect to the plans referred to below and with respect to the compensation of
the CEO for 2003.

     2003 COMPANY PERFORMANCE.  Because financial performance is a critical
driver of executive compensation, the following is an overview of the Company's
2003 performance. This past year was an exceptional year for W. R. Berkley
Corporation as the Company delivered record results:

     * Return on stockholders' equity rose to 25.3%, the highest in nearly three
       decades, surpassing the Company's targeted return of 15%

     * The Company's combined ratio performance in 2003 exceeded the industry's
       overall combined ratio performance by more than 1,000 basis points

     * Net income reached a new high of $3.87 per share, advancing 75% over 2002

     * Net premiums written increased 35% to $3.7 billion

     * Cash flow from operations increased 50% to $1.4 billion

     * Total stockholder return over the three year period ending December 31,
       2003 was 71%

     Through the leadership of the CEO and the other executive officers, the
Company achieved these results by capitalizing on increasing insurance prices
and improving insurance policy terms and conditions, while improving the
Company's market position relative to its competitors.

                                        12


     BASE SALARY.  With respect to base compensation in 2003 for executive
officers other than the CEO, the Committee considered the Company's performance,
past pay levels, existing market conditions and recommendations of the CEO with
respect to such compensation.

     ANNUAL INCENTIVE.  The annual incentive compensation for executive
officers, other than the CEO, for 2003 was based primarily on the achievement of
return on capital goals for 2003 set for the Company as a whole, and for those
executives with business segment responsibility, the specific business segment
returns. Additional individual goals were established for each executive based
on the strategic direction for the areas managed. Actual awards for 2003 were
determined by the CEO and reviewed with the Committee. The CEO provided the
Committee a summary performance review of each executive officer and the heads
of the significant operating units of the Company. Due to positive results in
many of the business segments, and for the Company as a whole, most executive
officers received an increase in annual incentive compensation over prior years.

     EQUITY-BASED COMPENSATION.  It has generally been the Company's practice to
grant stock options every other year, although the Committee may also grant
options from time to time in its discretion, and the Committee may change such
practice if it determines a change to be in the Company's best interest. Under
the 2003 Stock Incentive Plan, options and other equity-based awards can be
granted to the CEO and to other executives on a discretionary basis. In the
past, the Committee has exercised this discretion to make grants based on an
evaluation of each individual's ability to contribute to the Company's long-term
growth and profitability. In addition, the Committee has also considered the
level of a recipient's annual salary. In 2003, the Committee did not make grants
under the 2003 Stock Incentive Plan to the CEO or other executive officers.

     In April 2003, the Committee made restricted stock unit grants from the
Company's treasury shares to the CEO and certain executive officers. The
Committee believes that these restricted stock unit grants will provide a strong
retention vehicle for senior executives while further aligning their interests
with those of the stockholders. Alignment with stockholder interests comes not
only through stock price appreciation, but also through downside exposure and
the dividend stream. Restricted stock units for 97,500 shares of common stock
(adjusted for the 3 for 2 stock split) were granted to executive officers other
than the CEO. Grant date values for units granted to the five executive officers
whose compensation is disclosed in the proxy statement are set forth in the
Summary Compensation Table under the heading "Executive Compensation." These
restricted stock units vest after five years, with no incremental vesting of the
units during the five year period, and the receipt of the actual shares are
deferred until the executive retires from the Company or as otherwise provided
in the agreement. This deferral allows recipients to remain fully invested in
the Company and aligned with stockholders for the remainder of their careers.

     LONG-TERM INCENTIVE COMPENSATION PLAN.  No new units were awarded in 2003
under the LTIP. Outstanding awards were adjusted to reflect the 3 for 2 common
stock split that occurred in 2003. The units awarded in 2001 became fully vested
as of December 31, 2003 after reaching the maximum unit value. The maximum unit
value was achieved on an accelerated basis because the Company significantly
exceeded its expected performance during the relevant three-year period. Book
value per share grew by 71% and stock price grew by 67% over this period. The
Committee believes the LTIP provided management with proper incentives to
increase stockholder value. The Committee further noted that the units granted
originally under the LTIP in 1997 vested with a payout of less

                                        13


than ten percent of the maximum unit value, because the earnings per share goals
were not fully satisfied.

     The 2001 LTIP awards, representing 55,500 units in the aggregate, and
valued at $250 per unit, were paid to executive officers, including the CEO, on
February 12, 2004. Payment values for the five executive officers whose
compensation is disclosed in the proxy statement are set forth in the Summary
Compensation Table.

     CEO COMPENSATION.  In general, the CEO's compensation is based on the
Committee's evaluation of corporate performance and the CEO's individual
performance based on specific targets.

     With respect to base salary, based on the compensation philosophy stated
above and the advice of Ross, the Committee determined that the CEO's salary for
2003 should remain at $1,000,000.

     With respect to the CEO's annual incentive bonus for 2003, the Committee
established financial performance targets and individual performance goals for
the CEO. Quantitative financial goals represented 67% of the target annual
incentive compensation for the CEO and individual non-financial goals
represented 33% of that target. Quantitative financial performance targets were
based on the Company's earnings per share, net income, net premiums written,
return on equity and the Company's combined ratio as compared to industry. The
targets were then compared with actual Company performance to determine the
level of achievement and amount of annual incentive compensation earned by the
CEO for the quantitative portion of the award. At the beginning of the year, the
Committee and the CEO agreed upon several objective, individual non-financial
goals that were deemed to be in line with the strategic needs of the Company. At
the end of the year, the Committee reviewed achievement of these individual
non-financial goals to determine the amount of incentive compensation earned for
that component.

     Based on the results for 2003 outlined above, the Company exceeded target
performance with respect to all quantitative financial goals in 2003. The CEO
also achieved substantially all of the individual non-financial goals
established. As a result of these achievements, the Committee approved an annual
incentive payment for the CEO under the Annual Incentive Compensation Plan of
$4,933,562, which was above his target 2003 incentive compensation bonus amount,
but below the maximum amount allowable. This annual incentive bonus is disclosed
in the Summary Compensation Table.

     The Committee believes that the CEO's leadership has contributed greatly to
the Company's long-term financial strength and is important to the Company's
future earnings power. Therefore, as discussed earlier under Equity-Based
Compensation, restricted stock units for 202,500 shares of Common Stock
(adjusted for the 3 for 2 stock split) were granted to the CEO in April 2003.
These units vest at the end of five years, with no incremental vesting of the
units during the five year period, and the receipt of the actual shares is
deferred until retirement or as otherwise provided in the grant agreement. In
addition, for the financial period 2001 through 2003, the CEO earned an award
under the LTIP of 40,000 units, valued at $250 per unit, for a total of
$10,000,000, as described above under the heading Long-Term Incentive
Compensation Plan and as disclosed in the Summary Compensation Table.

     The Committee recognizes the long-standing stock ownership position of the
CEO and his continued commitment to the Company demonstrated by his acquisition
of additional shares of

                                        14


common stock of the Company from time to time. The Committee further notes that
the CEO has not sold any shares in over 25 years. The Committee believes this
level of commitment truly aligns the CEO with the long-term interests of the
stockholders.

     POLICY ON QUALIFYING COMPENSATION FOR DEDUCTIBILITY.  For purposes of
setting incentive compensation for the CEO, the Committee has determined that
the Company should consider the limitations on tax deductibility imposed under
Section 162(m) of the Internal Revenue Code. Section 162(m) disallows deductions
for compensation in excess of $1,000,000 per year paid by a public corporation
to certain of its executives unless certain criteria are met. In order to meet
the criteria, the Committee has determined that, subject to the matters
discussed below, the CEO's annual and long-term incentive compensation should be
structured as "qualified performance-based compensation," which is exempt from
the deduction limit. In general, this rule requires that the CEO's incentive
compensation be based on attainment of one or more objective performance goals,
which include quantitative financial goals and individual non-financial goals,
and that the Company's stockholders approve both the performance criteria and
the total amount that can be earned. For these reasons, the incentive
compensation for the CEO is generally payable and/or granted under the Company's
Annual Incentive Compensation Plan, LTIP and 2003 Stock Incentive Plan, each of
which was approved by stockholders of the Company and is designed so that
compensation payable thereunder, or attributable to the exercise of options,
will generally be exempt from the deduction limits. The Committee may, in its
discretion and where deemed appropriate, pay compensation to the CEO or other
executive officers in addition to compensation earned under these plans. Such
additional compensation may not be "qualified performance-based compensation"
and would not be exempt from the deduction limits. The Committee believes that
at times there are circumstances where the payment of such additional
compensation may be justified as a means of furthering the Company's interest in
retaining and rewarding its key personnel.

(1) These amounts reflect the 3-for-2 common stock split effected on August 27,
    2003.

(2) On April 4, 2003 the Company granted an aggregate of 450,000 restricted
    stock units ("RSUs") (on a split adjusted basis) to certain officers of the
    Company and its subsidiaries. Each RSU represents the right to receive one
    share of common stock, subject to vesting requirements and continued
    employment, following the recipient's termination of employment with the
    Company and its subsidiaries. Delivery of shares of common stock to the RSU
    recipients in satisfaction of the settlement of RSUs will be satisfied
    exclusively from treasury shares held by the Company. The RSUs held by any
    recipient will vest in full in one installment on April 4, 2008 (the
    "Vesting Date"), provided the recipient remains employed with the Company
    and/or its subsidiaries on the Vesting Date. If a recipient terminates
    employment prior to the Vesting Date on account of death, disability or
    retirement, a pro rata share of the number of RSUs granted to the recipient
    shall vest and be distributed to the recipient as of such termination date.
    Upon termination of employment for any other reason prior to vesting, all
    RSUs held by the recipient will expire and be forfeited. In the event of a
    Change of Control of the Company (as defined in the RSU Agreements) all RSUs
    will vest in full and the shares of common stock underlying each RSU will be
    delivered to the RSU recipients. The Compensation and Stock Option Committee
    of the Board retains the right to accelerate the vesting of any or all RSUs
    at any time, for any reason. The following list sets forth the names of the
    executive officers of the Company who received RSUs and the number of RSUs
    each individual received (on a split adjusted basis): William R. Berkley -
    202,500; William R. Berkley, Jr. - 15,000; Eugene G. Ballard - 15,000;
    Robert P. Cole - 11,250; Paul J. Hancock - 7,500; Robert C. Hewitt - 7,500;

    3,750; and James G. Shiel - 11,250; and an aggregate of 150,000 RSUs were
    granted to 24 other officers of the Company and its subsidiaries.

                   APPROVAL OF THE W. R. BERKLEY CORPORATION
                         2004 LONG-TERM INCENTIVE PLAN

     The Board submits to the stockholders for approval the W. R. Berkley
Corporation 2004 Long-Term Incentive Plan (the "LTIP"). The Board believes that
it is in the best interest of the Company and the stockholders to adopt the
LTIP. The LTIP is a cash-based plan that does not provide for the payment of any
equity compensation. It is designed to encourage teamwork among certain key
employees of the Company and its subsidiaries and affiliates to foster the
achievement of the Company's long-term goals, to reward these employees with pay
that relates to the Company's performance and to provide a means through which
the Company may attract, motivate and retain talented individuals who can assist
the Company in achieving its long-term goals. Compensation payable under the
LTIP is based on long-term corporate performance and is tied to an increase in
stockholder value.

     The LTIP is designed so that all compensation payable thereunder will be
fully deductible by the Company under Section 162(m) of the Internal Revenue
Code of 1986, as amended ("Section 162(m)"), and is being submitted to the
stockholders for the sole purpose of complying with the shareholder approval
requirements of Section 162(m). If the LTIP is not approved by the stockholders,
the LTIP will expire and all awards under the LTIP will become void.

     The following summary of the material features of the LTIP is qualified in
its entirety by the terms of the LTIP as filed with the Securities and Exchange
Commission.

TERM OF THE LTIP

     Provided the stockholders approve the LTIP and unless earlier terminated,
the LTIP has a 5-year term and will terminate on December 31, 2008. After the
LTIP is terminated, no awards may be granted but awards previously granted shall
remain outstanding in accordance with their applicable terms and conditions and
subject to the completion of the applicable performance period. Because
performance periods may last up to five (5) years, awards granted under the LTIP
in the last year of the term may accrue value through December 31, 2013.

ADMINISTRATION

     The LTIP will be administered by a committee appointed by the Board of
Directors. The Compensation and Stock Option Committee has been appointed to
administer the LTIP (the administrator of the LTIP is hereafter referred to as
the "Committee"). The Board of Directors may from time to time, in its
discretion, change the members of the Committee and/or appoint new members. The
Committee may, in certain circumstances, delegate its authority and
administrative duties under the LTIP to one or more of its members or to one or
more officers of the Company or its subsidiaries or affiliates.

     The Committee has full and exclusive discretionary power to administer the
LTIP, including interpreting the terms and the intent of the LTIP and any award
agreement or other agreement thereunder, selecting award recipients, granting
awards, establishing all terms and conditions for awards and making all other
determinations it deems necessary or proper for the administration of the LTIP.

                                        20


ELIGIBILITY

     Participation in the LTIP will be limited to key employees of the Company
and its subsidiaries and affiliates designated by the Committee. There are
approximately 275 key employees currently eligible for participation in the
LTIP.

PERFORMANCE UNITS

     The LTIP allows for the award of performance units ("Units") to key
employees in such amounts and upon such terms as determined by the Committee.
The Units are intended to provide value to the recipients based on the
attainment of certain performance goals set by the Committee over the course of
a specified performance period. Performance periods must be greater than one
year but no more than five years. The realization of value may, in addition, be
conditioned on certain vesting and continued employment conditions. At the end
of the performance period, or earlier upon specified trigger events, the award
recipients will receive a cash payment based on the degree of attainment of the
performance goals and other vesting conditions. The Committee also has the
authority to provide for accelerated vesting of any award based on the early
achievement of performance goals. The maximum aggregate amount awarded or
credited with respect to awards to any employee covered by Section 162(m) (a
"Covered Employee") in any one year during a performance period may not exceed
ten million dollars ($10,000,000) ("Annual Award Limit"), plus the amount of the
Covered Employee's unused applicable Annual Award Limit as of the close of the
previous year. Except as otherwise provided in an award agreement or as
otherwise determined at any time by the Committee, Units may not be sold,
transferred, pledged, assigned, or otherwise alienated or hypothecated, other
than to a designated beneficiary upon a participant's death, by will or by the
laws of descent and distribution.

PERFORMANCE MEASURES

     The performance goals, upon which the payment or vesting of any award to
any Covered Employee is contingent, are limited to the following performance
measures: net income; net income per share; aggregate or per share book value or
adjusted book value; written premiums (net or gross); return measures
(including, but not limited to, return on assets, capital, invested capital,
equity, sales, or premiums); cash flow (including, but not limited to, operating
cash flow, free cash flow, and cash flow return on capital); combined ratios (an
insurance industry measure of underwriting profitability, not including
investment income); EVA(R) (economic value added); share price (including, but
not limited to, growth measures and total shareholder return); and increase in
or maintenance of the Company's market share. The Committee may base performance
goals on other performance measures not listed above for awards granted to
individuals other than Covered Employees.

     Any one or more of these performance measure(s) may be used to measure the
performance of the Company, a subsidiary, and/or affiliate as a whole, or any
business unit of the Company, subsidiary, and/or affiliate, or any combination
thereof, or by comparison with the performance of one or more comparison
companies or business units, or any published or special index that the
Committee deems appropriate.

     The Committee may provide in any award that any evaluation of the
attainment of performance goals may include or exclude any of the following
events that occur during a performance period: asset write-downs; litigation or
claim judgments or settlements; the effect of changes in tax laws, accounting
principles, or other laws or provisions affecting reported results; any
reorganization and restructuring
                                        21


programs; extraordinary nonrecurring items as described in Accounting Principles
Board Opinion No. 30 and/or in management's discussion and analysis of financial
condition and results of operations appearing in the Company's annual report to
shareholders for the applicable year; acquisitions or divestitures; foreign
exchange gains and losses; and any stock repurchase programs.

DEFERRALS

     The Committee may permit or require an award holder to defer the receipt of
the payment of cash that would otherwise be due to such holder by virtue of the
satisfaction of any requirements or performance goals with respect to any
awards, subject to such rules and procedures the Committee may establish for the
purpose of permitting or requiring such deferrals.

CHANGE OF CONTROL

     The Committee may prescribe certain consequences for an award upon the
occurrence of a Change of Control (as defined in the LTIP), such as funding the
award through a rabbi trust or acceleration and payment of the award, and may
set forth such consequences in the award agreement.

TERMINATION AND AMENDMENT

     The Committee may, at any time and from time to time, alter, amend, modify,
suspend, or terminate the LTIP in whole or in part; provided, however, that no
amendment of the LTIP shall be made without stockholder approval if stockholder
approval is required by law, regulation, or stock exchange rule.

NEW PLAN BENEFITS

     Because the award of Units is within the discretion of the Committee, the
Company cannot determine the number and value of Units to be granted in the
future. Further, the Units are cash-based, not equity-based. The following table
sets forth the number of Units granted to the Chief Executive Officer and the
four other highest paid executive officers of the Company individually, all
executive officers as a group and all employees who are not executive officers
as a group, in each case, as of the date of this proxy statement. These Units
were granted subject to stockholder approval of the LTIP.

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

(1) The dollar value of Units granted in 2004 is not presently determinable
    because the value is based on the future attainment of certain performance
    goals. If the LTIP had been in effect in 2003 and these Units had been
    granted or outstanding in 2003, then based on the achievement of the 2004
    performance goals applied to actual performance in 2003, the assumed dollar
    value of each Unit

                                        22


    for fiscal 2003 would have been $42.11. Based on this number, the assumed
    aggregate 2003 value of Units granted to Messrs. Berkley, Shiel, McCleary,
    Ballard and Lederman would have been $1,684,400, $105,275, $105,275,
    $126,330 and $126,330, respectively; the assumed 2003 value of Units granted
    to all executive officers as a group would have been $2,631,875; and the
    assumed 2003 value of Units granted to all employees who are not executive
    officers as a group would have been $1,579,125. The Units granted in 2004
    are subject to a five (5) year performance period and are also subject to
    certain continued employment conditions, and the cumulative Unit values over
    the course of the performance period will be payable only at the end of such
    performance period, or earlier upon certain trigger events, and only to the
    extent such continued employment conditions are satisfied.

     THE BOARD OF DIRECTORS UNANIMOUSLY RECOMMENDS A VOTE "FOR" THE APPROVAL OF
THE W. R. BERKLEY CORPORATION 2004 LONG-TERM INCENTIVE PLAN.

               AMENDMENT OF RESTATED CERTIFICATE OF INCORPORATION
                      TO INCREASE AUTHORIZED COMMON STOCK

     The Board of Directors has unanimously voted to recommend that the
stockholders adopt an amendment to the Company's Restated Certificate of
Incorporation to increase the number of authorized shares of common stock from
150,000,000 shares to 300,000,000 shares. If the amendment is approved, the
shares may be issued from time to time by the Board of Directors. It is not
expected that further authorization from stockholders will be solicited for the
issuance of any shares of common stock, except to the extent such authorization
is required by law or by the rules of the New York Stock Exchange. Currently,
there is no agreement, arrangement or understanding relating to the issuance and
sale of the additional shares of common stock which would be authorized by the
proposed amendment. Stockholders do not have, and the proposed amendment would
not create, any preemptive rights.

     The Company currently has 150,000,000 shares of common stock authorized. At
December 31, 2003, there were 83,537,740 shares issued and outstanding, and
20,964,520 shares held in treasury. The Board believes it is desirable for the
Company to have a sufficient number of shares of common stock available, as the
occasion may arise, for possible future financings or acquisition transactions,
stock dividends or splits (such as the 3-for-2 stock splits effected in each of
2002 and 2003), stock issuances pursuant to employee benefit plans and other
proper corporate purposes. Having such additional shares available for issuance
in the future would give the Company greater flexibility by allowing shares to
be issued without incurring the delay and expense of a special stockholders'
meeting.

     THE BOARD OF DIRECTORS UNANIMOUSLY RECOMMENDS A VOTE "FOR" THE AMENDMENT OF
THE RESTATED CERTIFICATE OF INCORPORATION.

                      APPOINTMENT OF INDEPENDENT AUDITORS

     KPMG LLP has been appointed by the Board as independent certified public
accountants to audit the financial statements of the Company for the fiscal year
ending December 31, 2004. The appointment of this firm was recommended to the
Board by the Audit Committee. The Board is submitting this matter to a vote of
stockholders in order to ascertain their views. If the appointment of KPMG is
not ratified, the Board will reconsider its action and will appoint auditors for
the 2004 fiscal

                                        23


year without further stockholder action. Further, even if the appointment is
ratified by stockholder action, the Board may at any time in the future in its
discretion reconsider the appointment without submitting the matter to a vote of
stockholders.

     It is expected that representatives of KPMG will attend the Annual Meeting,
will have the opportunity to make a statement if they desire to do so and will
be available to respond to appropriate stockholder questions.

     THE BOARD OF DIRECTORS UNANIMOUSLY RECOMMENDS A VOTE "FOR" THE RATIFICATION
OF THE APPOINTMENT OF KPMG.

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

(1) Audit fees consist of fees the Company paid to KPMG for professional
    services for the audit of the Company's consolidated financial statements
    included in its Form 10-K and review of financial statements included in its
    Forms 10-Q, or for services that are normally provided by the accountant in
    connection with statutory and regulatory filings or engagements and public
    offerings of securities.

(2) Fees associated with the audit of health and benefit plans.

(3) Tax fees consist of fees for tax consultations and tax compliance services.

PRE-APPROVAL POLICIES

     Consistent with SEC policies regarding auditor independence, the Audit
Committee has adopted a policy regarding the pre-approval of services of the
Company's independent auditors. Pursuant to this policy, such services may be
generally pre-approved on an annual basis; other services, or services exceeding
the pre-approved cost levels, must be specifically pre-approved by the Audit
Committee. The Audit Committee may also delegate pre-approval authority to one
or more of its members. All of such fees for 2003 were approved by the Audit
Committee in accordance with this policy.

                             AUDIT COMMITTEE REPORT

To the Board of Directors of W. R. Berkley Corporation:

     The Audit Committee of the Board of Directors met with management and the
independent accountants, KPMG LLP, to review and discuss the December 31, 2003
financial statements. The Audit Committee also discussed with the independent
accountants the matters required by Statement on Auditing Standards No. 61
(Communication with Audit Committees). The Audit Committee also received written
disclosures from the independent accountants required by Independence Standards
Board Standard No. 1 (Independence Discussions with Audit Committees), and the
Audit Committee discussed with the independent accountants that firm's
independence.

     Based upon the Audit Committee's discussions with management and the
independent accountants, and the Audit Committee's review of the representations
of management and the independent accountants, the Audit Committee recommended
that the Board of Directors include the audited consolidated financial
statements in the Company's Annual Report on Form 10-K for the fiscal year ended
December 31, 2003, to be filed with the Securities and Exchange Commission.

                                          Audit Committee

                                          Mark L. Shapiro, Chairman
                                          Ronald E. Blaylock
                                          Philip J. Ablove
March 31, 2004

     The above report of the Audit Committee shall not be deemed incorporated by
reference by any general statement incorporating by reference this proxy
statement into any filing under the Securities Act of 1933 or under the
Securities Exchange Act of 1934, except to the extent that the Company
specifically incorporates this information by reference, and shall not otherwise
be deemed filed under such Acts.

                    OTHER MATTERS TO COME BEFORE THE MEETING

     Management is not aware of any matters to come before the Annual Meeting
other than as set forth above. However, since matters of which management is not
now aware may come before the Annual Meeting or any adjournment thereof, the
proxies intend to vote, act and consent in accordance with their best judgment
with respect thereto. Upon receipt of such proxies (in the form enclosed and
properly signed) in time for voting, the shares represented thereby will be
voted as indicated therein and in this proxy statement.

            SECTION 16(a) BENEFICIAL OWNERSHIP REPORTING COMPLIANCE

     Based solely on its review of the copies of Forms 3, 4 and 5 received by
it, or written representations from certain reporting persons that no Forms 5
were required for such persons, the Company believes that all filing
requirements under Section 16(a) of the Exchange Act applicable to its officers,
directors and ten-percent stockholders were complied with during the fiscal year
ended December 31, 2003, except that Jack H. Nusbaum, a director of the Company,
did not file a timely Form 4 with respect to the sale of 3,000 shares of the
Company's common stock in January 2002 by a trust of which he served as
co-trustee, and Robert W. Gosselink, Senior Vice President, Insurance
                                        25


Risk Management of the Company, did not file a timely Form 4 with respect 7,500
options granted to him in November 2003. Both of the foregoing filings have
since been made.

                  STOCKHOLDER NOMINATIONS FOR BOARD MEMBERSHIP
                  AND OTHER PROPOSALS FOR 2005 ANNUAL MEETING

     It is anticipated that the next Annual Meeting of Stockholders after the
one scheduled for May 11, 2004 will be held on or about May 10, 2005. The
Company's By-Laws require that, for nominations of directors or other business
to be properly brought before an Annual Meeting of Stockholders, written notice
of such nomination or proposal for other business must be furnished to the
Company. Such notice must contain certain information concerning the nominating
or proposing stockholder and information concerning the nominee and must be
furnished by the stockholder (who must be entitled to vote at the meeting) to
the Secretary of the Company, in the case of the Annual Meeting of Stockholders
to be held in 2005 no earlier than February 9, 2005 and no later than March 11,
2005. A copy of the applicable provisions of the By-Laws may be obtained by any
stockholder, without charge, upon written request to the Secretary of the
Company at the address set forth below.

     Since the Company did not receive timely notice of any stockholder proposal
for the 2004 Annual Meeting, it will have discretionary authority to vote on any
stockholder proposals presented at such meeting.

     In addition to the foregoing, and in accordance with the rules of the
Securities and Exchange Commission, in order for a stockholder proposal,
relating to a proper subject, to be considered for inclusion in the Company's
proxy statement and form of proxy relating to the Annual Meeting of Stockholders
to be held in 2005, such proposal must be received by the Secretary of the
Company by December 13, 2004 in the form required under and subject to the other
requirements of the applicable rules of the Securities and Exchange Commission.
Any such proposal should be submitted by certified mail, return receipt
requested, or other means, including electronic means, that allow the
stockholder to prove the date of delivery.

     A COPY OF THE COMPANY'S ANNUAL REPORT ON FORM 10-K FOR THE FISCAL YEAR
ENDED DECEMBER 31, 2003 IS AVAILABLE WITHOUT CHARGE TO ANY STOCKHOLDER OF THE
COMPANY WHO REQUESTS A COPY IN WRITING. REQUESTS FOR COPIES OF THIS REPORT
SHOULD BE DIRECTED TO THE SECRETARY, W. R. BERKLEY CORPORATION, 475 STEAMBOAT
ROAD, GREENWICH, CONNECTICUT 06830.

financial statements should be included in the Company's Form 10-K.

     2. Review and discuss with management and the independent auditor the
Company's quarterly financial statements prior to the filing of its Form 10-Q,
including Management Discussion and Analysis and the results of the independent

          (b) All alternative treatments of financial information within
     generally accepted accounting principles that have been discussed with
     management, ramifications of the use of such alternative disclosures and
     treatments, and the treatment preferred by the independent auditor.

          (c) Other material written communications between the independent
     auditor and management, such as any management letter or schedule of
     unadjusted differences.

                                       A-2


     5. Discuss with management the Company's earnings press releases, including
the use of "pro forma" or "adjusted" non-GAAP information, as well as financial
information and earnings guidance provided to analysts and rating agencies. Such
discussion may be done generally (consisting of discussing the types of
information to be disclosed and the types of presentations to be made).

     6. Discuss with management and the independent auditor the effect of
regulatory and accounting initiatives as well as off-balance sheet structures on
the Company's financial statements.

     7. Discuss with management the Company's major financial risk exposures and
the steps management has taken to monitor and control such exposures, including
the Company's risk assessment and risk management policies.

     8. Discuss with the independent auditor the matters required to be
discussed by Statement on Auditing Standards No. 61 relating to the conduct of
the audit, including any difficulties encountered in the course of the audit
work, including any restrictions on the scope of activities or access to
requested information, and any significant disagreements with management.

     9. Review disclosures made to the Audit Committee by the Company's CEO and
CFO during their certification process for the Form 10-K and Form 10-Q about any
significant deficiencies in the design or operation of internal controls or
material weaknesses therein and any fraud involving management or other
employees who have a significant role in the Company's internal controls.

      OVERSIGHT OF THE COMPANY'S RELATIONSHIP WITH THE INDEPENDENT AUDITOR

     1. Review and evaluate the lead partner of the independent auditor team.

     2. Obtain and review a report from the independent auditor at least
annually regarding (a) the independent auditor's internal quality-control
procedures, (b) material issues raised by internal-control reviews, peer reviews
or governmental or professional investigations of the firm, or by any inquiry or
investigation by governmental or professional authorities within the preceding
five years respecting one or more audits carried out by the firm, (c) any steps
taken to deal with such issues, and (d) all relationships between the
independent auditor and the Company. Evaluate the qualifications, performance
and independence of the independent auditor, including considering whether the
provision of permitted non-audit services is compatible with maintaining the
auditor's independence, and taking into account the opinions of management and
internal auditors. The Audit Committee shall present its conclusions with
respect to the independent auditor to the Board.

     3. Ensure the rotation of the lead audit partner having primary
responsibility for the audit and the audit partner responsible for reviewing the
audit as required by law.

     4. Recommend to the Board policies for the Company's hiring of employees or

                               Performance Units

     6.1 Grant of Performance Units.  Subject to the terms and provisions of the
Plan, the Committee, at any time and from time to time, may grant Performance
Units to Participants in such amounts and upon such terms as the Committee shall
determine.

     6.2 Value of Performance Units.  Each Performance Unit shall have an
initial value, which may be zero, that is established by the Committee at the

Period in its discretion which, depending on the extent to which they are met,
will determine the value of Performance Units that will be paid out to the
Participant.

     6.3 Earning of Performance Units.  Subject to the terms of this Plan, after
the applicable Performance Period has ended, the holder of Performance Units
shall be entitled to receive payout on the value and number of Performance Units
earned by the Participant over the Performance Period, to be determined as a
function of the extent to which the corresponding performance goals have been
achieved and may also be based on a Participant's continued employment.

     6.4 Form and Timing of Payment of Performance Units.  Payment of earned
Performance Units shall be as determined by the Committee and as evidenced in
the Award Agreement. Subject to the terms of the Plan, earned Performance Units
shall be paid in cash equal to the value of the earned Performance Units as soon
as practicable after the end of the Performance Period or as otherwise set forth
in the Award Agreement.

     6.5 Termination of Employment.  Each Award Agreement shall set forth the
extent to which the Participant shall have the right to retain Performance
Units, the extent to which such Performance Units shall be forfeited and the

                                       B-6


cash to the Participant at or following termination of the Participant's
employment with the Company, and all Affiliates and Subsidiaries, as the case
may be. Such provisions shall be determined in the sole discretion of the
Committee, shall be included in the Award Agreement entered into with each
Participant, need not be uniform among all Awards of Performance Units issued
pursuant to the Plan, and may reflect distinctions based on the reasons for
termination.

     6.6 Nontransferability.  Except as otherwise provided in a Participant's
Award Agreement or otherwise determined at any time by the Committee,
Performance Units may not be sold, transferred, pledged, assigned, or otherwise
alienated or hypothecated, other than to a designated beneficiary upon death, by
will or by the laws of descent and distribution.

                                   Article 7.

                              Performance Measures

     7.1 Performance Measures.  Unless and until the Committee proposes for
shareholder vote and the shareholders approve a change in the general
Performance Measures set forth in this Article 7, the performance goals upon
which the payment or vesting of an Award to a Covered Employee that is intended
to qualify as Performance-Based Compensation shall be limited to the following
Performance Measures:

     (a) Net income;

     (b) Net income per share;

     (c) Aggregate or per share book value or adjusted book value;

     (d) Written premiums (net or gross);

     (e) Return measures (including, but not limited to, return on assets,
         capital, invested capital, equity, sales, or premiums);

     (f) Cash flow (including, but not limited to, operating cash flow, free
         cash flow, and cash flow return on capital);

     (g) Combined ratios;

     (h) EVA(R);

     (i) Share price (including, but not limited to, growth measures and total
         shareholder return); and

     (j) Increase in or maintenance of the Company's market share.

     Any one or more Performance Measure(s) may be used to measure the
performance of the Company, Subsidiary, and/or Affiliate as a whole or any
business unit of the Company, Subsidiary, and/or Affiliate or any combination
thereof, or by comparison with the performance of one or more comparison
companies or business units, or published or special index that the Committee,
in its sole discretion, deems appropriate, or the Committee may select
Performance Measure (i) above as compared to various stock market indices. The
Committee also has the authority to provide for

                                       B-7


accelerated vesting of any Award based on the achievement of performance goals
pursuant to the Performance Measures specified in this Article 7.

     The Committee may base performance goals on other Performance Measures not
listed above for Awards granted to individuals other than Covered Employees. The
Performance Measures for any particular Award shall be set forth in the
applicable Award Agreement as determined by the Committee and need not be
uniform among Participants.

     7.2 Evaluation of Performance.  The Committee may provide in any such Award
that any calculation of performance may include or exclude any of the following
events that occur during a Performance Period: (a) asset write-downs, (b)
litigation or claim judgments or settlements, (c) the effect of changes in tax
laws, accounting principles, or other laws or provisions affecting reported
results, (d) any reorganization and restructuring programs, (e) extraordinary
nonrecurring items as described in Accounting Principles Board Opinion No. 30
and/or in management's discussion and analysis of financial condition and
results of operations appearing in the Company's annual report to shareholders
for the applicable year, (f) acquisitions or divestitures, (g) foreign exchange
gains and losses and (h) any stock repurchase programs. To the extent such
inclusions or exclusions affect Awards to Covered Employees, they shall be
prescribed in a form that meets the requirements of Code Section 162(m) for
deductibility.

     7.3 Adjustment of Performance-Based Compensation.  Awards that are designed
to qualify as Performance-Based Compensation, and that are held by Covered
Employees, may not be adjusted upward. The Committee shall retain the discretion
to adjust such Awards downward, either on a formula or discretionary basis or
any combination, as the Committee determines.

     7.4 Committee Discretion.  In the event that applicable tax and/or
securities laws change to permit Committee discretion to alter the governing
Performance Measures without obtaining shareholder approval of such changes, the
Committee shall have sole discretion to make such changes without obtaining
shareholder approval. In addition, in the event that the Committee determines
that it is advisable to grant Awards that shall not qualify as Performance-Based
Compensation, the Committee may make such grants without satisfying the
requirements of Code Section 162(m) and base vesting on Performance Measures
other than those set forth in Section 7.1.

                                   Article 8.

                            Beneficiary Designation

     Each Participant under the Plan may, from time to time, name any
beneficiary or beneficiaries (who may be named contingently or successively) to
whom any benefit under the Plan is to be paid in case of his or her death before
he or she receives any or all of such benefit. Each such designation shall
revoke all prior designations by the same Participant, shall be in a form
prescribed by the Committee, and will be effective only when filed by the
Participant in writing with the Company during the Participant's lifetime. In
the absence of any such designation, earned benefits remaining unpaid at the
Participant's death shall be paid to the Participant's estate.

                                       B-8

                                   Deferrals

     The Committee may permit or require a Participant to defer such
Participant's receipt of the payment of cash that would otherwise be due to such
Participant by virtue of the satisfaction of any requirements or performance
goals with respect to Awards. If any such deferral election is required or
permitted, the Committee shall, in its sole discretion, establish rules and
procedures for such payment deferrals.

                                  Article 10.

                             Rights of Participants

     10.1 Employment.  Nothing in the Plan or an Award Agreement shall interfere
with or limit in any way the right of the Company, an Affiliate or Subsidiary to
terminate any Participant's employment any time or for any reason not prohibited
by law, nor confer upon any Participant any right to continue his or her
employment for any specified period of time.

     Neither an Award hereunder nor the Plan nor any benefits arising under this
Plan shall constitute an employment contract between the Participant and the
Company, an Affiliate or Subsidiary and, accordingly, shall not restrict or
prohibit the Company, an Affiliate or Subsidiary from terminating such
Participant's employment at any time and for any reason.

     10.2 Participation.  No individual shall have the right to be selected to
receive an Award under this Plan, or, having been so selected, to be selected to
receive a future Award.

                               Change of Control

prohibited under applicable laws or by the rules and regulations of any
governing governmental agencies or national securities exchanges, the treatment
of any outstanding Awards shall be governed by the provisions of the applicable
Award Agreements.

Section 12.2, the Committee may, at any time and from time to time, alter,
amend, modify, suspend, or terminate the Plan and any Award Agreement in whole
or in part; provided, however, that no amendment of the Plan shall be made
without shareholder approval if shareholder approval is required by law,
regulation, or stock exchange rule.

     12.2 Awards Previously Granted.  Notwithstanding any other provision of the
Plan to the contrary but subject to Section 7.3 herein, no termination,
amendment, suspension, or modification of

                                       B-9


the Plan or an Award Agreement shall adversely affect in any material way any

federal, state, and local taxes, domestic or foreign, required by law or
regulation to be withheld with respect to any taxable event arising as a result
of this Plan.

merger, consolidation, or otherwise, of all or substantially all of the business
and/or assets of the Company.

                                  Article 15.

reduction, cancellation, forfeiture, or recoupment upon the occurrence of
certain specified events, in addition to any otherwise applicable vesting or
performance conditions of an Award. Such events may include, but shall not be
limited to, termination of employment for cause, termination of the
Participant's provision of services to the Company, an Affiliate, and/or
Subsidiary, violation of material Company, Affiliate, and/or Subsidiary
policies, breach of noncompetition, confidentiality, or other restrictive
covenants that may apply to the Participant, or other conduct by the Participant
that is detrimental to the business or reputation of the Company, any
Affiliates, and/or Subsidiaries.

     (b) Any amounts payable to Participants under this Plan shall be subject to
forfeiture as and to the extent provided in Section 304 of the Sarbanes-Oxley
Act of 2002 or other applicable law.

     15.2 Gender and Number.  Except where otherwise indicated by the context,
any masculine term used herein also shall include the feminine, the plural shall
include the singular, and the singular shall include the plural.

     15.3 Severability.  In the event any provision of the Plan shall be held
illegal or invalid for any reason, the illegality or invalidity shall not affect
the remaining parts of the Plan, and the Plan shall be construed and enforced as
if the illegal or invalid provision had not been included.

                                       B-10


     15.4 Requirements of Law.  The granting of Awards under the Plan shall be
subject to all applicable laws, rules, and regulations, and to such approvals by
any governmental agencies or national securities exchanges as may be required.

     15.5 Unfunded Plan.  Participants shall have no right, title, or interest
whatsoever in or to any investments that the Company, a Subsidiary or Affiliate
may make to aid the Company in meeting its obligations under the Plan. Nothing
contained in the Plan, and no action taken pursuant to its provisions, shall
create or be construed to create a trust of any kind (other than a rabbi trust,
as described below, if instituted), or a fiduciary relationship between the
Company and any Participant, beneficiary, legal representative, or any other
person. To the extent that any person acquires a right to receive payments from
the Company under the Plan, such right shall be no greater than the right of an
unsecured general creditor of the Company, a Subsidiary, or an Affiliate, as the
case may be. All payments to be made hereunder shall be paid from the general
funds of the Company, a Subsidiary or an Affiliate, as determined by the
Committee and no special or separate fund shall be established and no
segregation of assets shall be made to assure payment of such amounts; provided,
however, that the Company may establish a grantor trust within the meaning of
IRS Revenue Procedure 92-64 (a "rabbi trust") and fund such trust for the
purpose of providing payments when due hereunder.

     15.6 Retirement and Welfare Plans.  Neither Awards made under the Plan nor
cash paid pursuant to such Awards may be included as "compensation" for purposes
of computing the benefits payable to any Participant under the Company's or any
Subsidiary's or Affiliate's retirement plans (both qualified and non-qualified)
or welfare benefit plans unless such other plan expressly provides that such
compensation shall be taken into account in computing a participant's benefit.

     15.7 Nonexclusivity of the Plan.  The adoption of this Plan shall not be
construed as creating any limitations on the power of the Board or Committee to
adopt such other compensation arrangements as it may deem desirable for any
Participant.

     15.8 No Constraint on Corporate Action.  Nothing in this Plan shall be
construed to: (i) limit, impair, or otherwise affect the Company's or a
Subsidiary's or an Affiliate's right or power to make adjustments,
reclassifications, reorganizations, or changes of its capital or business
structure, or to merge or consolidate, or dissolve, liquidate, sell, or transfer
all or any part of its business or assets; or, (ii) limit the right or power of
the Company or a Subsidiary or an Affiliate to take any action which such entity
deems to be necessary or appropriate.

     15.9 Governing Law.  The Plan and each Award Agreement shall be governed by
the laws of the State of Delaware, excluding any conflicts or choice of law rule
or principle that might otherwise refer construction or interpretation of the
Plan to the substantive law of another jurisdiction. Unless otherwise provided
in the Award Agreement, recipients of an Award under the Plan are deemed to
submit to the exclusive jurisdiction and venue of the federal or state courts of
Delaware, to resolve any and all issues that may arise out of or relate to the
Plan or any related Award Agreement.
