existing at law or in equity or by statute or otherwise.

         waiver, nor as an acquiescence in any default, nor shall any single or
         partial exercise of any right or remedy preclude any other of further
         exercise thereof or the exercise of any other right or remedy.

                  6.4 This Note may not be modified or discharged except by a
         writing duly executed by the Payor and the Payee.

         8.       Investment Representations.
                  ---------------------------

                  8.1 The Payee has been provided with access to all information
         deemed to be relevant by the Payor in connection with this debt
         financing and concerning the Payor and the proposed operations of the
         Payor for the purpose of making an informed investment decision as to
         the purchase of the Note subscribed for hereby.

                  8.2 The Payee is a corporation organized and legally existing
         under the laws of the Isle of Man is an accredited investor as defined
         in Rule 501(a) of Regulation D of the Securities Act of 1933 (the
         "Act").

                  8.3 The Payee acknowledges that the offer and sale of the Note
         is being made without the use of a Private Placement Memorandum. The
         Payee understands and has

                                       5
<PAGE>

         evaluated the merits and risks of an investment in the Payor and the
         purchase of the Note. The Payee acknowledges that (i) the purchase of
         the Note is a speculative investment and involves a high degree of
         risk; (ii) no Federal or State agency has made any finding or
         determination as to the fairness of such investment or any
         recommendation or endorsement of it; (iii) there is not and will not be
         in the foreseeable future a market for the sale of the Note by the
         Payee, and (iv) the operations of the Payor are dependent on the
         Payor's ability to generate substantial income or to secure additional
         financing, and there can be no assurance that such income will be
         generated and there are no existing arrangements with respect to such
         financing being available and no assurance that it will become
         available.

                  8.4 The Payee is able to bear the economic risk of an
         investment in the Payee and the purchase of the Note in that, among
         other factors, such Payee can afford to hold Note for an indefinite
         period and can afford a complete loss of the investment in the Payee.

                  8.5 The Payee is relying solely on the financial and tax
         advice of his own advisor(s) with respect to an investment in the Payee
         and the purchase of the Note.

                  8.6 The Payee is acquiring the Note for his own account as
         principal and not with a view to resale or distribution.

                  8.7 All documents, records and books pertaining to the sale of
         the Note or the existing or projected operations of the Payor have been
         made available for inspection to the Payee, and the books and records
         of the Payor will be available upon reasonable notice, for inspection
         by Payee during reasonable business hours at its principal place of
         business.

                  8.8 The Payee has not authorized any broker, dealer, agent or
         finder to act on his behalf, nor has any knowledge of any broker,
         dealer, agent or finder purporting to act on his behalf, with respect
         to this transaction.

         9.       Miscellaneous.

         fully performed therein.

         (g) Person: An individual, partnership, joint venture, corporation,
trust, unincorporated organization or government of any department or agency
thereof.

         (h) Sale of the Corporation: A consolidation or merger of the
Corporation with or into any other corporation or corporations (other than a
consolidation or merger in which the Corporation is the continuing Corporation),
or a sale, conveyance or disposition of all or substantially all of the assets

                                   ARTICLE II

                        DURATION AND EXERCISE OF WARRANT

         Section 2.01: Duration of Warrant. The Warrantholder may exercise this
Warrant at any time and from time to time after 9:00 A.M., Florida time, on
February 8, 2000, and before 5:00 P.M., Florida time, on the Expiration Date. If
this Warrant is not exercised on the Expiration Date, it shall become void, and
all rights hereunder shall thereupon cease.

         Section 2.02: Exercise of Warrant.
         ------------  -------------------

         (a) The Warrantholder may exercise this Warrant, in whole or in part,
by presentation and surrender of this Warrant to the Corporation at its
principal corporate office or at the office of its stock transfer agent, if any,
with the subscription form attached hereto as Exhibit A (the "Subscription
Form") duly executed and accompanied by payment of the full Exercise Price for
each Warrant Share to be purchased.

         (b) Upon receipt of this Warrant with the Subscription Form fully
executed and accompanied by payment of the aggregate Exercise Price for the
Warrant Shares for which this Warrant is then being exercised, the Corporation
shall cause to be issued certificates for the total number of whole shares of
Common Stock for which this Warrant is being exercised in such denominations as
are requested for delivery to the Warrantholder registered in the name of the
Warrantholder or its nominee, and the Corporation shall thereupon deliver such
certificates to the Warrantholder. The Warrantholder shall be deemed to be the
holder of record of the shares of Common Stock issuable upon such exercise,
notwithstanding that the stock transfer books of the

                                       2
<PAGE>

Corporation shall then be closed or that certificates representing such shares
of Common Stock shall not then be actually delivered to the Warrantholder.

         (c) In lieu of exercising the Warrant in the manner set forth in
sub-paragraph 2.02(a) and (b) above, and subject to the last sentence of this
sub-paragraph 2.02(c), this Warrant may be exercised without payment of any
other consideration, commission, or remuneration, by presentation and surrender
of the Warrant to the Corporation, together with a written notice of the
Warrantholder's intention to effect a cashless exercise ("Notice of Cashless
Exercise") and the Subscription Form, duly executed. In the event of a Cashless
Exercise, the number of shares to be issued in exchange for the Warrant will be
computed using the following formula:

                                  X = Y (A-B)/A

where:

                    X =  the number of shares of Common Stock to be issued to
                         the Warrantholder.
                    Y =  the number of shares of Common Stock for which this
                         Warrant is being exercised.
                    A =  the Closing Bid Price. The Closing Bid Price means
                         the closing bid price per share of the Common Stock on
                         the last business day prior to the date of receipt of
                         the Warrant, the Notice of Cashless Exercise, and the
                         Subscription Form, on the principal national securities
                         exchange in the United States on which the Common Stock
                         is listed or admitted to trading, or if the Common
                         Stock is not listed or admitted to trading on any such
                         national securities exchange, the average of the
                         highest reported bid and lowest reported asked price,
                         on such day, as furnished by the National Association
                         of Securities Dealers, Inc. ("Nasdaq") through its
                         automated quotation system or a similar organization if
                         Nasdaq is no longer reporting such information.
                    B =  the Warrant Exercise Price

For purposes of Rule 144 and sub-section (d)(3)(iii) thereof, it is intended,
understood and acknowledged that the Common Stock issuable upon exercise of this
Warrant in a cashless exercise transaction shall be deemed to have been acquired
at the time this Warrant was issued. Moreover, it is intended, understood and
acknowledged that the holding period for the Common Stock issuable upon exercise
of this Warrant in a cashless exercise transaction shall be deemed to have
commenced on the date this Warrant was issued. Notwithstanding anything to the
contrary contained herein, this Warrant may not be exercised in a cashless
exercise transaction if, on the Date of Exercise, the shares of Common Stock to
be issued upon exercise of this Warrant would upon such issuance be then
registered pursuant to an effective and current registration statement.

         (c) In case the Warrantholder shall exercise this Warrant with respect
to less than all of the Warrant Shares that may be purchased under this Warrant,
the Corporation shall execute a new warrant in the form of this Warrant for the
balance of such Warrant Shares and deliver such new warrant to the
Warrantholder.

                                       3
<PAGE>

         (d) The Corporation shall pay any and all stock transfer and similar
taxes which may be payable in respect of the issue of any Warrant Shares to the
Warrantholder.

         Section 2.03: Reservation of Shares. The Corporation hereby agrees that
at all times there shall be reserved for issuance and delivery upon exercise of
this Warrant such number of shares of Common Stock from time to time issuable
upon exercise of this Warrant. All such shares shall be duly authorized, and
when issued upon such exercise, shall be validly issued, fully paid and
nonassessable, free and clear of all liens, security interests, charges and
other encumbrances or restrictions on sale and free and clear of all preemptive
rights.

         Section 2.04: Fractional Shares. The Corporation shall not be required
to issue any fraction of a share of its capital stock in connection with the
exercise of this Warrant, and in any case where the Warrantholder would, except
for the provisions of this Section 2.04, be entitled under the terms of this
Warrant to receive a fraction of a share upon the exercise of this Warrant, the
Corporation shall, upon the exercise of this Warrant and receipt of the Exercise
Price, issue the largest number of whole shares purchasable upon exercise of
this Warrant. The Corporation shall, in lieu of issuing any fractional share pay
the Warrantholder a sum in cash equal to the fair market value of any such
fractional interest as determined in good faith by the Corporation.

         Section 2.05: Listing. Prior to the issuance of any shares of Common
Stock upon exercise of this Warrant, the Corporation shall secure the listing of
such shares of Common Stock upon each national securities exchange or automated
quotation system, if any, upon which shares of Common Stock are then listed
(subject to official notice of issuance upon exercise of this Warrant) and shall
maintain, so long as any other shares of Common Stock shall be so listed, such
listing of all shares of Common Stock from time to time issuable upon the
exercise of this Warrant; and the Corporation shall so list on each national
securities exchange or automated quotation system, and shall maintain such
listing of, any other shares of capital stock of the Corporation issuable upon
the exercise of this Warrant if and so long as any shares of the same class
shall be listed on such national securities exchange or automated quotation
system.

                                   ARTICLE III

                      ADJUSTMENT OF SHARES OF COMMON STOCK
                        PURCHASABLE AND OF EXERCISE PRICE

         The Exercise Price and the number and kind of Warrant Shares shall be
subject to adjustment from time to time upon the happening of certain events as
provided in this Article III.

         Section 3.01:  Mechanical Adjustments.
         ------------   ----------------------

         (a) In case the Corporation shall at any time or from time to time
after the date hereof (i) pay any dividend, or make any distribution, on the
outstanding shares of Common Stock (or Common Stock Equivalents) in shares of
Common Stock, (ii) subdivide the outstanding shares of

                                       4
<PAGE>

Common Stock, (iii) combine the outstanding shares of Common Stock into a
smaller number of shares or (iv) issue by reclassification of the shares of
Common Stock any shares of capital stock of the Corporation, then and in each
such case, the Exercise Price in effect immediately prior to such event or the
record date therefor, whichever is earlier, shall be adjusted so that the
Warrantholder shall be entitled to receive the number and type of shares of
Common Stock which such Warrantholder would have owned or have been entitled to
receive after the happening of any of the events described above, had such
Warrant been converted into Common Stock immediately prior to the happening of
such event or the record date therefor, whichever is earlier. An adjustment made
pursuant to this Section 3.01(a) shall become effective (x) in the case of any
such dividend or distribution, immediately after the close of business on the
record date for the determination of holders of shares of Common Stock entitled
to receive such dividend or distribution, or (y) in the case of such
subdivision, reclassification or combination, at the close of business on the
day upon which such corporate action becomes effective.

         (b) Except with respect to Excluded Securities (as defined below), in
case the Corporation shall issue any shares of Common Stock (or Common Stock
Equivalents) after the date hereof at a consideration per share (or having a
conversion or exercise price per share) less than the Exercise Price, then in
each such case, the Exercise Price shall be adjusted by multiplying (i) the
Exercise Price in effect on the day immediately prior to the date of issuance of
such shares (or Common Stock Equivalents) by (ii) a fraction, the numerator of
which shall be the sum of (x) the number of shares of Common Stock outstanding
on such date prior to such issuance and (y) the number of shares of Common Stock
purchasable at the then Exercise Price with the aggregate consideration
receivable by the Corporation for the total number of shares of Common Stock so
issued (or issuable upon conversion, exchange or exercise of such Common Stock
Equivalents), and the denominator of which shall be the sum of (x) the number of
shares of Common Stock outstanding on such date prior to such issuance and (y)
the number of additional shares of Common Stock issued (or issuable upon
conversion, exchange or exercise of such Common Stock Equivalents.) An
adjustment made pursuant to this Section 3.01(b) shall be made on the next
Business Day following the date on which any such issuance is made and shall be
effective retroactively to the close of business on the date of such issuance.
For purposes of this Section 3.01(b), the aggregate consideration receivable by
the Corporation in connection with the issuance of shares of Common Stock or of
Common Stock Equivalents shall be deemed to be equal to the sum of the aggregate
offering price (e.g., the aggregate consideration received by the Corporation in
connection with the issuance of all such Common Stock and/or Common Stock
Equivalents before deduction of underwriting discounts or commissions and
expenses payable to third parties, if any) of all such Common Stock and/or
Common Stock Equivalents plus the minimum aggregate amount, if any, payable upon
conversion, exchange or exercise of any such Common Stock Equivalents. The
issuance or reissuance of any shares of Common Stock (whether treasury shares or
newly issued shares) pursuant to a dividend or distribution on, or subdivision,
combination or reclassification of, the outstanding shares of Common Stock
requiring an adjustment in the Exercise Price pursuant to Section 3.01(a) shall
not be deemed to constitute an issuance of Common Stock or Common Stock
Equivalents by the Corporation to which this Section 3.01(b) applies. Upon the
expiration of any unconverted, unexchanged or unexercised Common Stock
Equivalents for which an adjustment has been made pursuant to this

                                       5
<PAGE>

Section 3.01(b), the adjustments shall forthwith be reversed to effect such
Exercise Price as would have been in effect if at the time of such Common Stock
Equivalents, to the extent outstanding immediately prior to such expiration or
termination, had never been issued. Excluded Securities shall mean all shares of
Common Stock or Common Stock Equivalents (i) issued and outstanding upon the
Initial Investment Date, or (ii) issued or issuable pursuant to the 1999
Employee Stock Option Plan, (iii) issued or issuable pursuant to the 1999
Non-Employee Director Stock Option Plan, and (iv) executive options issued to
James A Brown in connection with his employment.

         (c) For purposes of Subsections (a) through (d) of this Section 3.01,
the number of shares of Common Stock at any time outstanding shall mean the
aggregate of all shares of Common Stock then outstanding (other than any shares
of Common Stock then owned or held by or for the account of the Corporation)
treating for purposes of this calculation all Common Stock Equivalents as having
been converted, exchanged or exercised.

         (d) If the Corporation shall take a record of the holders of its Common
Stock for the purpose of entitling them to receive a dividend or other
distribution and shall thereafter, and before such dividend or distribution is
paid or delivered to stockholders entitled thereto, legally abandon its plan to
pay or deliver such dividend or distribution, then no adjustment in the Exercise
Price then in effect shall be made by reason of the taking of such record, and
any such adjustment previously made as a result of the taking of such record
shall be reversed.

         (e) As used in this Section 3.01 the term "Common Stock" shall mean and
include the Corporation's authorized Common Stock, par value $.001 per share, as
constituted on the date hereof, and shall also include any capital stock of any
class of the Corporation thereafter authorized which shall neither be limited to
a fixed sum or percentage in respect of the rights of the holders thereof to
participate in dividends nor be entitled to a preference in the distribution of
assets upon the voluntary or involuntary liquidation, dissolution or winding up
of the Corporation.

         (f) In the case of a Sale of the Corporation or a proposed
reorganization of the Corporation or a proposed reclassification of the capital
stock of the Corporation (except a transaction for which provision for
adjustment is otherwise made in this Section 3.01), the Warrant shall thereafter
be exercisable into the number of shares of stock or other securities or
property to which a holder of the number of shares of Common Stock of the
Corporation deliverable upon exercise of such Warrant would have been entitled
upon such Sale of the Corporation, reorganization or reclassification; and, in
any such case, appropriate adjustment (as determined by the Board of Directors)
shall be made in the application of the provisions herein set forth with respect
to the rights and interest thereafter of the holders of the Warrant, to the end
that the provisions set forth herein (including provisions with respect to
changes in and other adjustments of the applicable conversion price) shall
thereafter be applicable, as nearly as reasonably may be, in relation to any
shares of stock or other property thereafter deliverable upon the exercise of
the Warrant. The Corporation shall not effect any such Sale of the Corporation
unless prior to or simultaneously with the consummation thereof the successor
Corporation or

                                       6
<PAGE>

purchaser, as the case may be, shall assume by written instrument the obligation
to deliver to the Warrantholder such shares of stock, securities or assets as,
in accordance with the foregoing provisions, each such holder is entitled to
receive.

         (g) Whenever the Exercise Price payable upon exercise of each Warrant
is adjusted pursuant to paragraph (a) or (b) of this Section 3.01, the Warrant
Shares shall simultaneously be adjusted by multiplying the number of Warrant
Shares initially issuable upon exercise of each Warrant (as set forth on the
front page of this Warrant) by $15.00 and dividing the product so obtained by
the Exercise Price, as adjusted.

         (h) No adjustment in the Exercise Price shall be required unless such
adjustment would require an increase or decrease of at least one cent ($.01) in
such price; provided, however, that any adjustments which by reason of this
paragraph (h) are not required to be made shall be carried forward and taken
into account in any subsequent adjustment. All calculations under this Section
3.01 shall be made to the nearest cent or to the nearest one-hundredth of a
share, as the case may be. Notwithstanding anything in this Section 3.01 to the
contrary, the Exercise Price shall not be reduced to less than the then existing
par value of the Common Stock as a result of any adjustment made hereunder.

         (i) In the event that at any time, as a result of any adjustment made
pursuant to Section 3.01(a), the Warrantholder thereafter shall become entitled
to receive any shares of capital stock of the Corporation other than Common
Stock, thereafter the number of such other shares so receivable upon exercise of
any Warrant shall be subject to adjustment from time to time in a manner and on
terms as nearly equivalent as practicable to the provisions with respect to the
Common Stock contained in Section 3.01(a).

         Section 3.02: Notices of Adjustment. Whenever the number of Warrant
Shares or the Exercise Price is adjusted as herein provided, the Corporation
shall prepare and deliver forthwith to the Warrantholder a certificate signed by
its President or a Vice President, or by the Treasurer or an Assistant Treasurer
or the Secretary or an Assistant Secretary, setting forth the adjusted number of
shares purchasable upon the exercise of this Warrant and the Exercise Price of
such shares after such adjustment, setting forth a brief statement of the facts
requiring such adjustment and setting forth the computation by which adjustment
was made.

         Section 3.03: Form of Warrant After Adjustments. The form of this
Warrant need not be changed because of any adjustments in the Exercise Price or
the number or kind of the Warrant Shares, and Warrants theretofore or thereafter
issued may continue to express the same price and number and kind of shares as
are stated in this Warrant, as initially issued.

         Section 3.04: Treatment of Warrantholder. Prior to due presentment for
registration of transfer of this Warrant, the Corporation may deem and treat the
Warrantholder as the absolute owner of this Warrant (notwithstanding any
notation of ownership or other writing hereon) for all purposes and shall not be
affected by any notice to the contrary.

                                   ARTICLE IV

              OTHER PROVISIONS RELATING TO RIGHTS OF WARRANTHOLDER

         Section 4.01: No Rights as Shareholders; Notice to Warrantholders.
Nothing contained in this Warrant shall be construed as conferring upon the
Warrantholder the right to vote or to receive dividends or to consent or to
receive notice as a shareholder in respect of any meeting of shareholders for
the election of directors of the Corporation or of any other matter, or any
rights whatsoever as shareholders of the Corporation. The Corporation shall give
notice to the Warrantholder by certified mail if at any time prior to the
expiration or exercise in full of the Warrants, any of the following events
shall occur:

         (a) the Corporation shall declare any dividend or distribution with
respect to its capital stock;

         (b) a dissolution, liquidation or winding up of the Corporation shall
be proposed; or

         (c) a capital reorganization or reclassification of the capital stock
of the Corporation, any consolidation or merger of the Corporation with or into
another corporation, any transaction or series of transactions in which more
than fifty percent (50%) of the voting securities of the Corporation are
transferred to another person, or of any sale or conveyance to another
corporation of the property of the Corporation as an entirety or substantially
as an entirety.

         Such giving of notice shall be initiated at least ten Business Days
prior to the date fixed as a record date or effective date or the date of
closing of the Corporation's stock transfer books for the determination of the
shareholders entitled to such dividend or distribution, or for the determination
of the shareholders entitled to vote on such proposed merger, consolidation,
sale, conveyance, dissolution, liquidation or winding up. Such notice shall
specify such record date or the date of closing the stock transfer books, as the
case may be.

         Section 4.02: Lost, Stolen, Mutilated or Destroyed Warrants. If this
Warrant is lost, stolen, mutilated or destroyed, the Corporation may, on such
reasonable terms as to indemnity or otherwise as it may in its reasonable
discretion impose (which shall, in the case of a mutilated Warrant, include the
surrender thereof), issue a new Warrant of like denomination and tenor as, and
in substitution for, this Warrant.

                             SPLIT-UP, COMBINATION,
                        EXCHANGE AND TRANSFER OF WARRANTS

         Section 5.01: Split-Up, Combination, Exchange and Transfer of Warrants.
Subject to the provisions of Section 5.02 hereof, this warrant may be split up,
combined or exchanged for another Warrant or Warrants containing the same terms
to purchase a like aggregate number of Warrant Shares. If the Warrantholder
desires to split up, combine or exchange this Warrant, the Warrantholder shall
make such request in writing delivered to the Corporation and shall surrender to
the Corporation this Warrant and any other Warrants to be so split-up, combined
or exchanged. Upon any such surrender for a split-up, combination or exchange,
the Corporation shall execute and deliver to the person entitled thereto a
Warrant or Warrants, as the case may be, as so requested. The Corporation shall
not be required to effect any split-up, combination or exchange which will
result in the issuance of a Warrant entitling the Warrantholder to purchase upon
exercise a fraction of a share of Common Stock or a fractional Warrant. The
Corporation may require such Warrantholder to pay a sum sufficient to cover any
tax or governmental charge that may be imposed in connection with any split-up,
combination or exchange of Warrants.

         Section 5.02: Transfer. This Warrant and all rights hereunder may be
sold, transferred or otherwise disposed of, in whole or in part, to any person
in accordance with and subject to the provisions of the Securities Act of 1933,
as amended (the "Securities Act"), and the rules and regulations promulgated
thereunder. Upon the delivery to the Corporation at its principal corporate
office of this Warrant along with a duly completed Assignment Form substantially
in the form of Exhibit B hereto, the Corporation shall execute and deliver a new
Warrant in the form of this Warrant, but registered in the name of the
transferee, to purchase the number of Warrant Shares assigned to the transferee.
In case the Warrantholder shall assign this Warrant with respect to less than
all of the Warrant Shares that may be purchased under this Warrant, the
Corporation shall execute a new warrant in the form of this Warrant for the
balance of such Warrant Shares and deliver such new warrant to the
Warrantholder.

         Section 5.03: Restrictive Legend. Each Warrant Share issued upon
exercise of this Warrant shall bear a legend containing the following words:

           "THE SECURITIES REPRESENTED BY THIS CERTIFICATE HAVE NOT BEEN
           REGISTERED UNDER THE SECURITIES ACT OF 1933, AS AMENDED. THE
           SECURITIES HAVE BEEN ACQUIRED FOR INVESTMENT AND MAY NOT BE
           SOLD, TRANSFERRED OR OTHERWISE DISPOSED OF EXCEPT IN
           COMPLIANCE WITH SUCH ACT."

The requirement that the above legend be placed upon certificates evidencing any
such securities shall cease and terminate upon the earliest of the following
events: (i) when such shares are

                                       9
<PAGE>

transferred in an underwritten public offering, (ii) when such shares are
transferred pursuant to Rule 144 under the Securities Act or (iii) when such
shares are transferred in any other transaction if the seller delivers to the
Corporation an opinion of its counsel, which counsel and opinion shall be
reasonably satisfactory to the Corporation, or a "no-action" letter from the
Staff of the Securities and Exchange Commission, in either case to the effect
that such legend is no longer necessary in order to protect the Corporation
against a violation by it of the Securities Act upon any sale or other
disposition of such shares without registration thereunder. Upon the occurrence
of such event, the Corporation, upon the surrender of certificates containing
such legend, shall, at its own expense, deliver to the holder of any such
securities as to which the requirement for such legend shall have terminated,
one or more new certificates evidencing such securities not bearing such legend.

                                   ARTICLE VI

                                  OTHER MATTERS

         Section 6.01: Successors and Assigns. The terms and provisions of this
Warrant shall bind and inure to the benefit of the Warrantholder and its
successors and assigns.

         Section 6.02: No Inconsistent Agreements. The Corporation will not on
or after the date of this Warrant enter into any agreement with respect to its
securities which is inconsistent with the rights granted to the Warrantholder or
otherwise conflicts with the provisions hereof. The rights granted to the
Warrantholder hereunder do not in any way conflict with and are not inconsistent
with the rights granted to holders of the Corporation's securities under any
other agreements.

         Section 6.03: Entire Agreement. This Warrant and the Exhibits hereto
contain the entire agreement among the parties with respect to the subject
matter hereof and supersede all prior and contemporaneous arrangements or
understandings with respect thereto.

         Section 6.04: Amendments and Waivers. The terms and provisions of this
Warrant, including the provisions of this sentence, may be modified or amended,
or any of the provisions hereof waived, temporarily or permanently, pursuant to
the written consent of the Corporation and the Warrantholder.

         Section 6.05: Counterparts. This Warrant may be executed in any number
of counterparts, and each such counterpart hereof shall be deemed to be an
original instrument, but all such counterparts together shall constitute but one
agreement.

         Section 6.06: Governing Law. This Warrant shall be governed by and
construed in accordance with the laws of the State of Florida without giving
effect to the principles of conflicts of law. Each of the parties hereto hereby
irrevocably and unconditionally consents to submit to the exclusive jurisdiction
of the courts of the State of Florida and of the United States

                                       10
<PAGE>

of America, in each case located in the County of Palm Beach, for any action,
proceeding or investigation in any court or before any governmental authority
("Litigation") arising out of or relating to this Warrant and the transactions
contemplated hereby (and agrees not to commence any Litigation relating thereto
except in such courts), and further agrees that service of any process, summons,
notice or document by U.S. registered mail to its respective address set forth
in this Warrant shall be effective service of process for any Litigation brought
against it in any such court. Each of the parties hereto hereby irrevocably and
unconditionally waives any objection to the laying of venue of any Litigation
arising out of this Warrant or the transactions contemplated hereby in the
courts of the State of Florida or the United States of America, in each case
located in the County of Palm Beach, and hereby further irrevocably and
unconditionally waives and agrees not to plead or claim in any such court that
any such Litigation brought in any such court has been brought in an
inconvenient forum.

         Section 6.07: Notice. All notices, requests, consents and other
communications hereunder to any party shall be deemed to be sufficient if
contained in a written instrument delivered in person or sent by telecopy,
