         2.       REPRESENTATIONS OF PARKER AND JOAN PARKER. Each of Parker and
Joan Parker hereby represents and warrants to the Proxy that he/she: (a) has
full power to enter into this Agreement and has not, prior to the date of this
Agreement, executed or delivered any proxy or entered into any other voting
agreement or similar arrangement and (b) will not take any action inconsistent
with the purposes and provisions of this Agreement.

         3.       SCOPE OF AGREEMENT. This Agreement shall govern the vote of
the Proxy Shares by the Proxy with respect to any and all matters concerning a
shareholder vote in respect of the Proxy Shares, whether at a meeting or
pursuant to written consent or otherwise, including, but not limited to the
election of the Company's Board of Directors. Unless terminated as hereinafter
provided, this Agreement shall remain in effect without regard to any action
taken by either Parker or Joan Parker. This Agreement pertains to voting rights
with respect to the Proxy Shares and does not confer on the Proxy cash or stock
dividends, distributions, disposition of Proxy Shares or proceeds from the sale
or other disposition of Proxy Shares.

         4.       CHANGES IN CAPITAL STOCK. In the event that subsequent to the
date of this Agreement any shares of capital stock or other securities the
Company are issued on, or in exchange for, any of the Proxy Shares by reason of
any stock dividend, stock split, consolidation of shares, reclassification,
exchange, merger or consolidation or otherwise involving the Company, such
shares of capital stock or other securities shall be deemed to be Proxy Shares
for purposes of this Agreement.

         5.       VOTING OF PROXY SHARES. Each of Parker and Joan Parker agrees
and covenants that at any meeting of the shareholders of the Company and/or in
connection with any corporate action by the shareholders of the Company, all of
their respective shares of the Proxy Shares shall be voted by the Proxy in the
manner and to the effect determined by said Proxy in his sole and absolute
discretion. Accordingly, during the term of this Agreement, neither Parker nor
Joan Parker shall vote or attempt to vote any of their respective shares of the
Proxy Shares, or otherwise exercise or attempt to exercise any voting or other
approval rights of any of their respective shares of the Proxy Shares, and any
such prohibited exercise by either Parker or Joan Parker of voting or approval
rights shall be void and of no force or effect.

         6.       IRREVOCABLE PROXY.

                  (a)      In order to give effect to and in furtherance of the
agreements and covenants set forth in Section 5 of this Agreement, each of
Parker and Joan Parker hereby irrevocably constitutes and appoints Proxy as
proxy for Parker or Joan Parker, as the case may be, with full power of
substitution, for and in the name and on behalf of Parker or Joan Parker, as
the case may be, to vote any and all of their respective shares of Proxy Shares
with regard to any question, action, resolution, election or other matter
presented to the shareholders of the Company for vote or approval. Proxy shall
vote said Proxy Shares in such manner and to such effect as he may determine in
his sole and absolute discretion. The proxy granted hereby shall remain in
effect for so long as and at all times that this Agreement shall remain in
effect and shall terminate immediately and automatically only upon the
termination of this Agreement in accordance with the provisions hereof. The
proxy granted hereby is irrevocable and is coupled with an interest, as
provided in Section 607.0722(5) of the Florida Business Corporation Act.

                  (b)      Proxy hereby accepts his appointment as proxy of
each of Parker and Joan Parker, pursuant to Subsection 6(a) of this Agreement.
Other than as specifically set forth herein, the Proxy shall have no other
rights with respect to the Proxy Shares.

         7.       LIMITATION OF PROXY'S LIABILITY. Proxy shall not incur any
liability or responsibility by reason of any error of judgment, mistake of law
or other mistake, or for any act or omission of any agent or attorney, or for
any misconstruction of this Agreement, or for any action of any kind taken or
omitted hereunder or believed by him to be in accordance with the provisions
and intents hereof.

         8.       TERMINATION. This Agreement shall terminate only upon the
earliest to occur of the occurrence of any one of the following events:

                  (a)      the fifth (5th) anniversary of the Execution Date of
                           this Agreement;

                  (b)      the date upon which Leeds is no longer an executive
                           officer and director of the Company;

                  (c)      the reorganization, merger, consolidation or similar
                           corporate transaction whereby the persons who were
                           the shareholders of the Company immediately prior to
                           the transaction do not, immediately thereafter, own
                           more than 50% of the combined voting power entitled
                           to vote;

                  (d)      the sale of all, or substantially all, of the assets
                           of the Company; or

                  (e)      the termination of this Agreement by the Proxy.

         9.       SUCCESSOR PROXY. In the event that the Proxy is unable or
unwilling to serve as the Proxy, a successor Proxy may be appointed by the
Proxy at his discretion, or if the Proxy is unable to make such appointment due
to his death or incapacity to act, by the consent of the successors to the
Proxy's individual shares of Stock that hold a majority interest in such
shares. A successor Proxy shall be vested with all the rights, powers and
authority as if originally named in this Agreement.

         10.      LEGEND; SUBSEQUENT HOLDERS OF PROXY SHARES. Upon execution of
this Agreement, each of Parker and Joan Parker hereby acknowledges and agrees
that all certificates for the shares of Proxy Shares may, but need not, be
imprinted by the Proxy with notice of this Agreement and the irrevocable proxy
set forth herein. Each of Parker and Joan Parker agrees not to transfer any
interest in their respective Proxy Shares unless the transferee executes and
delivers to Proxy an agreement in form and in substance substantially similar
to this Agreement; provided, however, a purchaser of any Proxy Shares that are
purchased in the market in a Rule 144 transaction or pursuant to a public
offering registered on a Form S-1, Form SB-2, Form S-8 or similar form required
by the Securities Exchange Commission for the public distribution of securities
shall not be subject to this Agreement; and provided further, up to 500,000
Proxy Shares to be transferred to Harry Green and/or Jack Root by Parker shall
not be subject to this Agreement.

         11.      GOVERNING LAW; JURISDICTION AND VENUE. This Agreement shall
be governed by and construed in accordance with the laws of the State of
Florida, without regard to rules regarding choice of law. EACH PARTY HERETO
AGREES TO SUBMIT TO THE PERSONAL JURISDICTION AND VENUE OF THE STATE AND/OR
FEDERAL COURTS LOCATED IN PALM BEACH COUNTY, FLORIDA FOR RESOLUTION OF ALL
DISPUTES ARISING OUT OF, IN CONNECTION WITH, OR BY REASON OF THE
INTERPRETATION, CONSTRUCTION, AND ENFORCEMENT OF THIS AGREEMENT, AND HEREBY
WAIVES THE CLAIM OR DEFENSE THEREIN THAT SUCH COURTS CONSTITUTE AN INCONVENIENT
FORUM.
