                  (a) In the event the Company shall (i) declare a dividend on
         its Common Stock in shares of Common Stock or make a distribution in
         shares of Common Stock, (ii) declare a stock split or reverse stock
         split of its outstanding shares of Common Stock; (iii) combine its
         outstanding shares of Common Stock into a smaller number of shares of
         Common Stock or (iv) issue by reclassification of its shares of Common
         Stock other securities (including any such reclassification in
         connection with a consolidation or merger in which the Company or any
         of its subsidiaries is the continuing corporation), then the number of
         shares of Common Stock of the Company deliverable to Optionee hereunder
         and the exercise price related thereto shall be adjusted so that the
         Optionee shall be entitled to receive the kind and number of shares of
         Common Stock of the Company which the Optionee has the right to
         receive, upon the happening of any of the events described above, with
         respect to the shares of the Common Stock which were otherwise
         deliverable pursuant hereto and the exercise price per share thereof
         shall be adjusted so that the same percentage of the Company's issued
         and outstanding shares of capital stock shall remain subject to
         purchase at the same aggregate exercise price. An adjustment made
         pursuant to this paragraph shall become effective immediately after the
         effective date of such event;

                  (b) In the event of any consolidation or merger to which the
         Company is a party other than a merger or consolidation in which the
         Company is the continuing corporation, or in case of any sale or
         conveyance to another entity of the property of the Company as an
         entirety or substantially as an entirety, or in the case of any
         statutory exchange of securities with another corporation (including
         any exchange effected in connection with a merger of a third
         corporation into the Company), as a condition to any such
         consolidation, merger or sale, the Company shall secure the agreement
         of the surviving corporation or purchaser, in a manner reasonably
         satisfactory to the Optionee, that the Optionee shall have the right
         thereafter to convert this Option into the kind and amount of
         securities, cash or other property which he would have owned or have
         been entitled to receive immediately after such consolidation, merger,
         statutory exchange, sale or conveyance had the Option been exercised
         immediately prior to the effective date of such consolidation, merger,
         statutory exchange, sale or conveyance and in any such case, if
         necessary, appropriate adjustment shall be made in the application of
         the provisions set forth in this Section 7 shall thereafter
         correspondingly be made applicable, as nearly as may reasonably be, in
         relation to any shares of stock or other securities or property
         thereafter deliverable on the exercise of this Option. The above
         provisions of this Subsection 7(b) shall similarly apply to successive
         consolidations, mergers, statutory exchanges, sales or conveyances.
         Notice of any such consolidation, merger, statutory exchange, sale or
         conveyance and of said provisions so proposed to be made, shall be
         mailed to the Optionee not less than 20 days prior to such event. A
         sale of all or substantially all of the assets of the Company for a




                                       3
<PAGE>   4

         consideration consisting primarily of securities shall be deemed a
         consolidation or merger for the foregoing purposes.

                  (c) Whenever the number of Shares or the exercise price of
         this Option is adjusted pursuant to this paragraph, the Company shall
         promptly mail by first class mail, postage prepaid, to Optionee, notice
         of such adjustment or adjustments.

                  (d) Unless otherwise provided in any Option, each outstanding
         Option shall become immediately fully exercisable.

                  (i)      If there occurs any transaction (which shall include
                           a series of transactions occurring within 60 days or
                           occurring pursuant to a plan), that has the result
                           that shareholders of the Company immediately before
                           such transaction cease to own at least 51 percent of
                           the voting stock of the Company or of any entity that
                           results from the participation of the Company in a
                           reorganization, consolidation, merger, liquidation or
                           any other form of corporate transaction;

                  (ii)     If the shareholders of the Company shall approve a
                           plan of merger, consolidation, reorganization,
                           liquidation or dissolution in which the Company does
                           not survive (unless the approved merger,
                           consolidation, reorganization, liquidation or
                           dissolution is subsequently abandoned); or

                  (iii)    If the shareholders of the Company shall approve a
                           plan for the sale, lease, exchange or other
                           disposition of all or substantially all the property
                           and assets of the Company (unless such plan is
                           subsequently abandoned).

         8. AVAILABILITY OF COMPANY STOCK. The Company hereby agrees and
covenants that at all times during the Exercise Period it shall reserve for
issuance a sufficient number of shares of Common Stock as would be required upon
full exercise of the Option represented by this Agreement

         9. APPROVAL OF STOCK OPTION PLAN. The Company intends, at its next
Annual Meeting of Shareholders (the "ANNUAL MEETING"), to submit for shareholder
consideration and approval its 1997 Stock Option Plan (the "PLAN"). In the event
that the Plan is approved by the Company's shareholders, then this Option shall
be deemed to be an Incentive Stock Option (within the meaning of the Internal
Revenue Code of 1986, as amended, (the "Code") have been granted under and
pursuant to the Plan. If, however, the Plan is not so approved at the Annual
Meeting, then this Option shall be deemed to be a non-qualified stock option
(which means any option which is not an Incentive Stock Option under the Code).

         10. NO RIGHT TO EMPLOYMENT. Nothing in this Agreement shall interfere
with or limit in any way the right of the Company to terminate the Optionee's
employment at any time, nor confer upon the Optionee any right to continue in
the employ of the Company or any Subsidiary (subject, in each case, to the
Optionee's Employment Agreement with the Company);

         11. GOVERNING LAW. This Agreement shall be governed by the laws of the
State of Florida.

         12. TERMS OF EMPLOYMENT AGREEMENT TO CONTROL. In the event of any
conflict between the terms of this Agreement and the Employment Agreement, the
terms of the Employment Agreement shall be deemed to prevail.
