Section 3. Amount of Deferral

Prior to the beginning of each calendar year, a Participant may elect to defer
receipt of:

(a) all or a portion of the Bonus Pay Compensation payable to the Participant
    for that year;

                                     and/or

(c) all or part of the Profit Sharing Excess Contributions (as defined below).
    For the purposes hereof, a Participant's "Profit Sharing Excess
    Contributions" for any year means the excess of (a) the contributions that
    would be made by the Company to the W. R. Berkley Corporation Profit Sharing
    Plan (the "Profit Plan") on behalf of the Participant for such year
    (exclusive of any pre-tax (401(k)) contributions), without taking into
    account the Profit Plan's limitations on a participant's earnings and
    maximum annual additions under Sections 401(a) (17) and 415 of the Internal
    Revenue Code, over (b) the actual amount of Company contributions (exclusive
    of pre-tax (401(k))contributions) allocated to the Participant under the
    Profit Plan for such year.

All amounts deferred will be classified as "Deferred Compensation."

Section 4. Type of Plan

The Plan is a non-qualified voluntary deferred compensation type of plan.

Section 5. Funding

The Company will not fund the amount of any Participant's Deferred Compensation.
The amount of Deferred Compensation is secured only by the Company's promise to
pay it from the assets of the Company

Section 6. Investment Income

A reasonable rate of interest will be credited to a Participant's account, from
the first of the month following the date of the deferral, and will be
compounded quarterly. The interest rate will be established by the Compensation
Committee of the Board of Directors prior to the beginning of each year.

Section 7. Deferral Period

A Participant may elect to defer his/her Bonus Pay Compensation and/or his/her
Base Salary and/or his/her Excess Profit Sharing Contribution either (a) until a
specified year in the future (but not later than his/her termination of
employment) or (b) until his/her termination of service or retirement. The
actual payment will be made or will commence within sixty days after the date
specified or the actual date of termination of service or retirement.

Section 8. Form of Payment

A Participant may elect to receive his/her Deferred Compensation under the Plan
in either a lump sum or in annual installments (not to exceed five), as
specified by the Participant at the time the election to defer is made.

Section 9. Death Prior to Receipt

In the event that a Participant dies prior to receipt of any or all of the
amounts payable to him/her pursuant to this Plan, any amounts that are then
credited as Deferred Compensation will be paid to his/her designated beneficiary
in a lump sum within sixty days following the Company's notification of the
Participant's death.

At the time the election to defer is made, a Participant may designate a
beneficiary under this Plan. The Participant may change the beneficiary by
writing to the General Counsel of the Company. If a beneficiary is not named,
the value of the Participant's Deferred Compensation Account will be paid to
his/her estate.

Section 10. Effect of Election

An election to defer Compensation for any year will be irrevocable once the term
to which it applies has commenced, and can be revoked or modified only on a
showing of severe financial hardship as a result of an unanticipated emergency,
as determined by the Compensation Committee of the Board of Directors of the
Company.

Section 11. Participant's Rights Unsecured

The right of any Participant to receive future payments under the provisions of
the Plan will be an unsecured contractual claim against the general assets of
the Company. The Plan will not be funded. The Company will not be required to
establish any special or separate fund or to make any segregation of assets to
assure the payment of any amounts under the Plan.

Section 12. Statement of Account

Statements will be sent to each Participant by February 15th each year as to the
value of his/her Deferred Compensation Account as of the end of the preceding
December.

Participant, except by will or by the laws of descent and distribution.

This Plan will be administered on a day-to-day basis on behalf of the
Compensation Committee of the Board of Directors of the Company by the General
Counsel of the Company, who will have the authority to adopt rules and
regulations for carrying out the Plan. The Compensation Committee of the Board
of Directors of the Company will have the authority to interpret, construe and
implement the provisions of the Plan and to prescribe the form of the request
for deferral of compensation under the Plan.

Section 15. Amendment/Termination

This Plan may at any time or from time to time be amended, modified or
terminated by the Board of Directors of the Company. No amendment, modification
or termination will, without the consent of the Participant, adversely affect
any amounts credited to such Participant's Deferred Compensation Account.

Section 16. Tax Treatment

Deferred Compensation and credited interest are taxed as ordinary income when
payment is actually received. Distributions received from the Plan are not
eligible for favorable tax treatment or rollovers as permitted under qualified
plans.

Section 17. Other Benefits

The computation and basis for other Company provided benefits may be affected if
a Participant elects to defer a portion of his/her Base Salary.
