Item 5.02 Departure of Directors or Certain Officers; Election of Directors;
Appointment of Certain Officers; Compensatory Arrangements of Certain Officers.

     In 2004, W. R. Berkley Corporation (the "Company") adopted and its
stockholders approved the W. R. Berkley Corporation 2004 Long-Term Incentive
Plan (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, as described in note 1 to the
table below. On March 7, 2008, the Company's Compensation Committee granted new
awards under the LTIP to certain key employees. The following table shows the
number of LTIP units ("Units") awarded to each of the Company's named executive
officers and the material terms of such awards:

(1) Each of these Units had a $-0- value at the time of grant. The future payout
value for each Unit is determined by multiplying the aggregate year-to-year
increase in the per-share book value of the Company's common stock over the
five-year performance period by a factor of 12.5, subject to a maximum per-Unit
value of $250.00. The aggregate dollar value of the award to each named
executive officer will be the product of that per-Unit value and the number of
Units awarded to each such executive. The dollar value of the awards will be
paid to the executives at the end of the five-year performance period, subject
to earlier payout of the earned value upon death or a termination of employment
on account of disability or eligible retirement or by the Company without
"cause", where such earned value will be based on the per-Unit value as of the
end of the fiscal year immediately preceding the year in which such death or
termination occurs. Upon a change in control of the Company, the value of the
Units will be fixed as of the end of the fiscal year immediately preceding the
year in which such change in control occurs and will be paid to each named
executive officer upon the earliest to occur of (a) the end of the five-year
performance period, (b) such executive's death, and (c) such executive's
termination of employment due to disability or retirement or by the Company
without "cause". An executive's Units will be forfeited if certain continued
employment conditions are not satisfied through the end of the performance
period. An executive's Units may also be forfeited or subject to recapture if
such executive violates certain non-competition provisions of the award during
the performance period and for two years following the end of the performance
period.
