designation of such Options as Incentive Stock Options or Nonstatutory Stock

any provisions of the Plan or of any Option granted thereunder shall be binding
and conclusive on all Optionees and their legal representatives and
beneficiaries.

         5.    Eligibility. Any Employee may be granted Incentive Stock Options

operation and development of the business of the Corporation.

         6.    Stock. The stock subject to Options granted under the Plan shall

under the Plan expires for any reason or is terminated, the Shares allocable to
the unexercised portion of such Option shall again be available for grant of
Options under the Plan.

         The limitations established by this Section 6 shall be subject to
adjustment upon the occurrence of the events specified and in the manner
provided in Section 9 hereof.

         7.    Terms and Conditions of Options. Options granted pursuant to the
Plan shall be evidenced by written agreements in such form as the Board or the
Committee shall from time to time determine, which agreements shall comply with
and be subject to the following terms and conditions:

               (a)   Date of Grant. Each Option shall specify its effective date
(the "date of grant"), which shall be the date specified by the Board or
Committee in its action relating to the grant of the Option, but which date
shall not be earlier than the date of the determination by the Board or
Committee to grant such Option nor more than thirty days after such date.

               (b)   Number of Shares. Each Option shall state the number of
Shares to which it pertains and shall provide for the adjustment thereof in
accordance with the provisions of Section 9 hereof.

               (c)   Exercise Price. Each Option shall state the Exercise Price,
which price shall be determined by the Board or Committee, provided however,
that the Exercise Price (i) in the case of an Incentive Stock Option granted to
an Employee who is not a Ten Percent Shareholder, shall not be less than the par
value nor less than the Fair Market Value of the Shares to which the Option
relates on the date of grant, (ii) in the case of an Incentive Stock Option
granted to an Employee who is a Ten Percent Shareholder, shall not be less than
the par value nor less than 110% of the Fair Market Value of the Shares to which
the Option relates on the date of grant, and (iii) in the case of a Nonstatutory
Stock Option granted to any Employee or officer or director of the Corporation,
shall not be less than the par value of the Shares to which the Option relates.
The Exercise Price of an

                                       -3-

Option shall be subject to adjustment in accordance with Section 9 hereof. The
Company may, at its discretion, permit the cashless exercise of Options in
accordance with the procedures and restrictions established by the Board or the
Committee.

               (d)   Exercise of Options and Medium and Time of Payment. To 
exercise an Option, the Optionee shall give written notice to the Company
specifying the number of Shares to be purchased and accompanied by payment in
cash or by certified check of the full Purchase Price therefor and the amount of
any withholding tax obligation of the Corporation as described in Section 14(a)
hereof. No Share shall be issued until full payment therefor has been made.

               (e)  Term and Exercise of Options; Non-Transferability of 
Incentive Stock Options. Subject to Section 10 hereof, Options may be exercised
as determined by the Board or Committee and as stated in the written agreement
evidencing the Option, provided, however, that no Incentive Stock Option granted
to an Employee who is not a Ten Percent Shareholder shall be exercisable after
the expiration of ten (10) years from the date it is granted, and no Incentive
Stock Option granted to an Employee who is a Ten Percent Shareholder shall be
exercisable after the expiration of five (5) years from the date it is granted.
In addition, the aggregate fair market value (determined at the time an
Incentive Stock Option is granted) of Shares with respect to which Incentive
Stock Options are exercisable for the first time by an Optionee during any
calendar year (under this Plan and all other plans maintained by the
Corporation) shall not exceed $100,000. During the lifetime of the Optionee, an
Incentive Stock Option shall be exercisable only by the Optionee and shall not
be assignable or transferable. In the event of the Optionee's death, no
Incentive Stock Option shall be transferable by the Optionee otherwise than by
will or by the laws of descent and distribution. Restrictions on the transfer of
Nonstatutory Stock Options, if any, shall be determined by the Board and set
forth in each Nonstatutory Stock Option Agreement.

               (f)   Termination of Employment. In the event that an Optionee
shall cease to be employed by the Corporation for any reason, such Optionee (or
the heirs or legatees of such Optionee, if applicable) shall have the right,
subject to the restrictions of Subsection (e) hereof, to exercise the Option at
any time within three (3) months after such termination of employment (twelve
(12) months if the termination was due to the death or Disability of the
Optionee or, in the case of a Nonstatutory Stock Option, retirement) to the
extent that, on the day preceding the date of termination of employment, the
Optionee's right to exercise such Option had accrued pursuant to the terms of
the option agreement pursuant to which such Option was granted, and had not
previously been exercised.

         For this purpose, the employment relationship will be treated as
continuing intact while the Optionee is on military leave, sick leave or other
bona fide leave of absence (to be determined in the sole discretion of the Board
and, in the case of an Optionee who has received an Incentive Stock Option, only
to the extent permitted under Section 422A of the Code and the regulations
promulgated thereunder). Moreover, in the case of an Optionee who has been
granted an Incentive Stock Option, employment shall, in no event, be deemed to
continue beyond the ninetieth (90th) day after the Optionee ceased active
employment, unless the Optionee's reemployment rights are guaranteed by statute
or by contract.

               (g)   Rights as a Shareholder. An Optionee or, in the case of
an Incentive Stock Option, a transferee of a deceased Optionee or, in the case
of a Nonstatutory Stock Option, a permitted transferee shall have no rights as a
shareholder with respect to any Shares covered by his or her Option until the
date of the issuance of a stock certificate for such Shares. No adjustment shall
be made for dividends (ordinary or extraordinary, whether in cash, securities or
other property) or distributions or other rights for which the record date is
prior to the date such stock certificate is issued, except as provided in
Section 9.

               (h)   Modification, Extension and Renewal of Options. Subject
to the terms and conditions and within the limitations of the Plan, the Board or
Committee may modify, extend or renew outstanding Options granted under the
Plan, or accept the exchange of outstanding Options (to the extent not
theretofore exercised) for the granting of new Options in substitution therefor.
Notwithstanding the foregoing, however, no modification of an Option shall,
without the consent of the Optionee, alter or impair any rights or obligations
under any Option theretofore granted under the Plan. Moreover, in the case of
any modification, extension or renewal of an Incentive Stock Option, all of the
requirements set forth herein shall apply in the same manner as though a new
Incentive Stock Option had been granted to the Optionee on the date of such
modification, extension or renewal, but only if such modification, extension or
renewal is treated, under Section 425(h) of the Code, as the granting of a new
option.

               (i)   Identification of Option. Each Option granted under the 
Plan shall clearly identify its status as an Incentive Stock Option or
Nonstatutory Stock Option.

               (j)   Other Provisions. The option agreements authorized under 
the Plan shall contain, in addition to those provisions provided in Section 7(e)
hereof, such other provisions not inconsistent with the terms of the Plan,
including, without I limitation, restrictions upon the exercise of any Option,
and restrictions upon the transfer of Shares received upon exercise of Options,
as the Board or Committee shall deem advisable.

         8.    Term of Plan. Options may be granted pursuant to the Plan ten
years from the date the Plan is approved by the Company's stockholders pursuant
to Section 3 hereof.

         9.    Recapitalization. Subject to any required action by the
shareholders and the last sentence of subsection 7(h) hereof, the number of
Shares covered by this Plan as provided in Section 6, the number of Shares
covered by each outstanding Option, and the Exercise Price thereof shall be
proportionately adjusted for any increase or decrease in the number of issued
Shares resulting from a subdivision or consolidation of Shares, stock split, or
the payment of a stock dividend.

         Subject to any required action by the shareholders of the Company and
the last sentence of Subsection 7(h) hereof, if the Company shall be the
surviving corporation in any merger or consolidation, each outstanding Option
shall pertain and apply to the securities to which a holder of the number of
Shares subject to the Option would have been entitled. A dissolution or
liquidation of the Company or a merger or consolidation in which the Company is
not the surviving corporation shall cause each outstanding Option to terminate,
unless the agreement of merger or consolidation shall

                                       -5-
<PAGE>   6




otherwise provide, provided that each Optionee shall, in such event, have the
right immediately prior to such dissolution or liquidation, or merger or
consolidation in which the Company is not the surviving corporation to exercise
the Option in whole or in part, subject to limitations on exercisability of
Options under Sections 7(e) and (f) hereof.

         In the event of a change in the Common Stock as presently constituted,
which is limited to a change of all of its authorized shares with par value into
the same number of shares with a different par value or without par value, the
shares resulting from any such change shall be deemed to be Shares of Common
Stock within the meaning of the Plan.

         To the extent that the foregoing adjustments relate to stock or
securities of the Company, such adjustments shall be made by the Board or
Committee, whose determination in that respect shall be final, binding and
conclusive.

         Except as hereinbefore expressly provided in this Section 9, the
Optionee shall have no rights by reason of any subdivision or consolidation of
shares of stock of any class, stock split, or the payment of any stock dividend
or any other increase or decrease in the number of shares of stock of any class
or by reason of any dissolution, liquidation, merger, or consolidation or
spin-off of assets or stock of another corporation, and any issue by the Company
of shares of stock of any class or securities convertible into shares of stock
of any class, shall not affect, and no adjustment by reason thereof shall be
made with respect to, the number or price of Shares subject to the Option.

         The grant of an Option pursuant to the Plan shall not affect in any way
the right or power of the Company to make adjustments, reclassifications,
reorganizations or changes of its capital or business structure or to merge or
consolidate or to dissolve, liquidate, sell or transfer all or any part of its
business or assets.

         10.   Securities Law Requirements. No Shares shall be issued upon the
exercise of any Option unless and until the Company has determined that: (i) it
and the Optionee have taken all actions required to register the Shares under
the Securities Act of 1933 or perfect an exemption from the registration
requirements thereof (including the furnishing by the Optionee of an appropriate
investment letter); (ii) any applicable listing requirement of any stock
exchange on which the Common Stock is listed has been satisfied; and (iii) any
other applicable provision of state or Federal law has been satisfied.

         11.   Amendment of the Plan. The Board or Committee may, insofar as
permitted by law, from time to time, with respect to any Shares at the time not
subject to Options, suspend or discontinue the Plan or revise or amend it in any
respect whatsoever except that, without approval of the shareholders of the
Company, no such revision or amendment shall:

               (a)   Increase the number of Shares subject to the Plan; or


               (b)   Change the designation in Section 5 of the Plan of the 
               class of Employees eligible to receive options.

                                       -6-

<PAGE>   7




               (c)   Amend this Section 11 to defeat its purpose.

         12.   Application of Funds. The proceeds received by the Company from 
the sale of Common Stock pursuant to the exercise of an Option will be used for
general corporate purposes or as otherwise determined by the Board.

         13.   No Obligation to Exercise Option. The granting of an Option shall
impose no obligation upon the Optionee to exercise such Option.

         14.   Withholding.

               (a)   Nonstatutory Options. Whenever Shares are to be delivered
upon exercise of a Nonstatutory Option, the Corporation shall be entitled to
require as a condition of delivery that the Optionee remit to the Corporation an
amount sufficient to satisfy the Corporation's federal, state and local
withholding tax obligations with respect to the exercise of the Option.

               (b)   Incentive Stock Options. The acceptance of Shares upon
exercise of an Incentive Stock Option shall constitute an agreement by the
Optionee (unless and until the Corporation shall notify the Optionee that it is
relieved, in whole or in part, of its obligations under this Section 14(b)) (i)
to notify the Corporation if any or all of such Shares are disposed of by the
Optionee within two years from the date the Option was granted or within one
year from the date the Shares were transferred to the Optionee pursuant to this
exercise of the Option, and (ii) to remit to the Corporation, at the time of and
in the case of any such disposition, an amount sufficient to satisfy the
Corporation's federal, state and local withholding tax obligations with respect
to such disposition, whether or not, as to both (i) and (ii), the Optionee is in
the employ of the Corporation at the time of such disposition.

         15.   Governing Law. The Plan shall be governed by the laws of the 
State of Florida.
