                  THIS NON-QUALIFIED STOCK OPTION AGREEMENT (this "Agreement"),
dated as of the Grant Date specified above, is entered into by and between
Brooke Group Ltd., a Delaware corporation (the "Company"), and the Optionee
specified above, pursuant to the Brooke Group Ltd. 1998 Long-Term Incentive
Plan, as in effect and as amended from time to time (the "Plan"); and

                  WHEREAS, it has been determined under the Plan that it would
be in the best interests of the Company to grant the non-qualified stock option
provided for herein to the Optionee (i) as an inducement to remain in the
employment of the Company (and/or one of its Subsidiaries), and (ii) as an
incentive for increased effort during such service;

                  NOW, THEREFORE, in consideration of the mutual covenants and
premises hereinafter set forth and for other good and valuable consideration,
the parties hereto hereby mutually covenant and agree as follows:

         1. INCORPORATION BY REFERENCE; PLAN DOCUMENT RECEIPT. This Agreement is
subject in all respects to the terms and provisions of the Plan (including,
without limitation, any amendments thereto adopted at any time and from time to
time if such amendments are expressly intended to apply to the grant of the
option hereunder), all of which terms and provisions are made a part of and
incorporated in this Agreement as if they were each expressly set forth herein.

<PAGE>   2

Any capitalized term not defined in this Agreement shall have the same meaning
as is ascribed thereto under the Plan. The Optionee hereby acknowledges receipt
of a true copy of the Plan and that the Optionee has read the Plan carefully and
fully understands its content. In the event of any conflict between the terms of
this Agreement and the terms of the Plan, the terms of the Plan shall control.

         2. GRANT OF OPTION. The Company hereby grants to the Optionee, as of
the Grant Date specified above, a non-qualified stock option (this "Option") to
acquire from the Company at the Per Share Exercise Price specified above the
aggregate number of shares of the Common Stock specified above (the "Option
Shares"). This Option is not to be treated as (and is not intended to qualify
as) an incentive stock option within the meaning of Section 422 of the Code.

         3. CASH PAYMENTS EQUIVALENT TO DIVIDENDS. The Optionee shall not be
entitled to receive a cash payment in respect of the Option Shares underlying
this Option on any dividend payment date for the Common Stock.

         4. EXERCISE OF THIS OPTION.

            4.1 Notwithstanding the provisions of Section 6.6 of the Plan,
unless otherwise determined by the Committee, this Option shall become
exercisable as to the aggregate number of shares of Common Stock underlying this
Option, as determined on the Date of Grant, as follows:

            o    25%, on December 31, 2001, provided the Optionee is then
                 employed by the Company and/or one of its Subsidiaries;

            o    62.5%, on December 31, 2002, provided the Optionee is
                 then employed by the Company and/or one of its
                 Subsidiaries; and

            o    100%, on December 31, 2003, provided the Optionee is
                 then employed by the Company and/or one of its
                 Subsidiaries.

However, any then unexercised portion of this Option shall immediately become
exercisable upon the termination of the Optionee's employment with the Company
and/or one of its Subsidiaries due to death or Disability.

            4.2 Unless earlier terminated in accordance with the terms and
provisions of the Plan and/or this Agreement, this Option shall expire and shall
no longer be exercisable after the expiration of ten years from the Date of
Grant (the "Option Period").

            4.3 In no event shall this Option be exercisable for a fractional
share of Common Stock.

therein, shall not be sold, exchanged, transferred, assigned or otherwise

laws of descent and distribution. This Option shall not be pledged, encumbered
or otherwise hypothecated in any way at any time by the Optionee (or any
beneficiary(ies) of the Optionee) and shall not be subject to execution,
attachment or similar legal process. Any attempt to sell, exchange, pledge,

Option, contrary to the terms of this Agreement and/or the Plan shall be null

without the consent of the Optionee. The Company shall give written notice to
the Optionee of any such modification or amendment of this Agreement as soon as
