                                                    Made, executed and delivered
                                                         in International Waters

         FOR VALVE RECEIVED, the undersigned, EARTHFIRST TECHNOLOGIES,
INCORPORATED (the "Borrower"), hereby promises to pay to the order of FLORIDA
ENGINEERED CONSTRUCTION PRODUCTS CORPORATION (hereinafter the "Lender"), in such
coin or currency of the United States which shall be legal tender in payment of
all debts and dues, public and private, at the time of payment, the principal
sum of Two Million Five Hundred Thousand and 00/100 Dollars ($2,500,000.00), or
so much as may be outstanding, together with interest from and after the date
hereof on the unpaid principal balance outstanding at the rate of ten percent
(10%). All principal, together with interest, shall be payable in full upon
demand.

         Borrower may prepay this Note in whole or in part at any time during
the term hereof, provided that any such payment shall first be applied to any
charges and costs then due and payable hereunder, then to interest, and finally
to principal.

         The occurrence of any default by Borrower hereunder shall entitle
Lender, at its option, to declare the then outstanding principal balance and
accrued interest hereof to be, and the same shall thereupon become, immediately
due and payable without notice to or demand upon Borrower, all of which Borrower
hereby expressly waives. If this Note is collected by or through an attorney at
law, then Borrower shall be obligated to pay, in addition to the principal
balance and accrued interest hereof, reasonable attorneys' fees and court costs
at trial, on any appeal, and in any bankruptcy proceedings.

         Time is of the essence of this Note. To the fullest extent permitted by
applicable law, Borrower, for itself and its legal representatives, successors
and assigns, expressly waives presentment, demand, protest, notice of dishonor,
notice of non-payment, notice of maturity, notice of protest, presentment for
the purpose of accelerating maturity, diligence in collection, and the benefit
of any exemption or insolvency laws.

         Wherever possible each provision of this Note shall be interpreted in
such a manner as to be effective and valid under applicable law, but if any
provision of this Note shall be prohibited or invalid under applicable law, such
provision shall be ineffective to the extent of such prohibition or invalidity
without invalidating the remainder of such provisions of this Note. No delay or
failure on the part of Lender in the exercise of any right or remedy hereunder
shall operate as a waiver thereof, nor as an acquiescence in any default, nor
shall any single or partial exercise by Lender of any right or remedy preclude
any other right or remedy.

shall not at any time exceed the principal sum of $2,500,000.00. Anything herein
to the contrary notwithstanding the right of the undersigned to request advances

                                    Party in the exercise of such right.

                           (ii)     RIGHT TO CONTROL PROCEEDS. The Secured Party
                                    may, at its option, take control of any and

                                    on any obligations payable to the Debtor,
                                    after deduction of all reasonable expenses
                                    incurred in collection of such accounts
                                    including, without limitation, all
                                    attorneys' fees and costs incurred by
                                    Secured Party or on its behalf.

                           (iii)    DEFICIENCY. The exercise of the Secured

                                    proceed directly against Debtor.

         14.      WAIVER OF RIGHTS.

                  (a)      All rights and remedies of the Secured Party as
                           provided in this Agreement, or as found in the
                           Promissory Note executed in connection with this
                           Agreement, or arising by operation of law shall
                           continue in full force and effect during the full
                           course of this Agreement unless specifically waived
                           by the Secured Party in a signed writing to that
                           effect.

                           remedy shall not constitute a waiver thereof and may
                           only be effected by a specific written agreement to
                           that effect which is signed by the Secured Party.

                  (c)      The exercise or partial exercise of any right or
                           remedy shall not preclude the further exercise of
                           such right or remedy.

         15.      CHOICE OF LAW. This Agreement shall be governed and

<PAGE>

be construed together as an agreement separate and independent of
any agreements, obligations or undertakings between the Secured Party and the
Debtor, or any of them, and the existence of any claim related to such other
agreements, obligations or undertakings between or among them shall not
constitute a defense to the enforcement of this Agreement or the Promissory Note
secured hereby, such defense(s) being expressly hereby waived by Debtor.

         17.      SEVERABILITY. In the event that any provision of this
Agreement shall be found to be unenforceable in any legal proceeding, the
remaining provisions shall remain in force and effect.

         18.      EXECUTION. This Agreement becomes effective when signed by the
Debtor.
