         a. The principal amount of this Note is subject to prepayment in whole
or in part upon the occurrence and during the continuance of any of the
following events (each, an "Event of Default"): the initiation of any

         b. No remedy herein conferred upon the Lender is intended to be
exclusive of any other remedy and each and every remedy shall be cumulative and
in addition to every other remedy hereunder, now or hereafter existing at law or
in equity or otherwise.

3. Notices.

         a. All notices, reports and other communications required or permitted
hereunder shall be in writing and may be delivered in person, by telecopy with
written confirmation, overnight delivery service or U.S. mail, in which event it

Purchase Agreement (or such other address as such Investor shall have furnished
the Company in writing) and (ii) if to the Company at the address set forth at
the beginning of the Purchase Agreement (or such other address as the Company
shall have furnished the Investors in writing).

         b. Each such notice, report or other communication shall for all
purposes under this Note be treated as effective or having been given when
delivered if delivered personally or, if sent by mail, at the earlier of its
receipt or 72 hours after the same has been deposited in a regularly maintained
receptacle for the deposit of the United States mail, addressed and mailed as
aforesaid, or, if sent by telecopier with written confirmation, at the earlier
of (i) 24 hours after confirmation of transmission by the sending telecopier
machine or (ii) delivery of written confirmation.

4. Miscellaneous.

         a. With the written consent of the record holders of more than 50% of
the principal amount of the Notes then outstanding, the obligations of the
Company and the rights of the holders under the Notes may be waived (either
generally or in a particular instance, either retroactively or prospectively and
either for a specified period of time or indefinitely), and with the same
consent the Company, when authorized by resolution of its Board of Directors,
may enter into a supplementary agreement for the purpose of adding any
provisions to or changing in any manner or eliminating any of the provisions of
this Note; provided, however, that no such waiver or supplemental agreement
shall reduce the above percentage of principal amount, the holders of which are
required to consent to any waiver or supplemental agreement, without the consent
of the record or beneficial holders of all of the Notes, nor increase the
obligations of any holder of a Note without such holder's written consent. Upon
the effectuation of each such waiver, consent, agreement, amendment or
modification the Company shall promptly give written notice thereof to the
record holders of the Notes who have not previously consented thereto in
writing. Neither this Note nor any provisions hereof may be changed, waived,
discharged or terminated orally, but only by a signed statement in writing.

                                       2

         b. No failure or delay by the Lender to exercise any right hereunder
shall operate as a waiver thereof, nor shall any single or partial exercise of
any right, power or privilege preclude any other right, power or privilege. The
provisions of this Note are severable and if any one provision hereof shall be
held invalid or unenforceable in whole or in part in any jurisdiction, such
invalidity or unenforceability shall affect only such provision in such
jurisdiction. This Note expresses the entire understanding of the parties with
respect to the transactions contemplated hereby. The Company and every endorser
and guarantor of this Note regardless of the time, order or place of signing
hereby waives presentment, demand, protest and notice of every kind, and assents
to any extension or postponement of the time for payment or any other
indulgence, to any substitution, exchange or release of collateral, and to the
addition or release of any other party or person primarily or secondarily
liable.

         (3) If Lender retains an attorney for collection of this Note, or if
any suit or proceeding is brought for the recovery of all, or any part of, or
for protection of the indebtedness respected by this Note, then the Company
agrees to pay all costs and expenses of the suit or proceeding, or any appeal
thereof, incurred by the Lender, including without limitation, reasonable
attorneys' fees.

         (4) This Note shall for all purposes be governed by, and construed in
accordance with the laws of the State of Florida (without reference to conflict
of laws).

         (5) This Note shall be binding upon the Company's successors and
assigns, and shall inure to the benefit of the Lender's successors and assigns.

         (6) In no event shall the interest rate and other charges under this
Note exceed the highest rate permissible under any law that a court of competent
jurisdiction shall, in a final determination, deem applicable hereto. In the
event that a court determines that Lender has received interest and other
charges under this Note in excess of the highest permissible rate applicable
hereto, such excess shall be deemed received on account of, and shall
automatically be applied to reduce, the outstanding principal amount hereunder
and the provisions thereof shall be deemed amended to provide for the highest
permissible rate. If there is no outstanding principal amount under this Note,
Lender shall refund such excess to the Company.
