give the Lender at least fourteen (14) Business Days' written or telegraphic
notice (effective upon receipt) of any Revolving Credit Loans under this
Agreement, specifying the date and amount thereof. Not later than 2:00 P.M. (New

Credit Loans shall be paid in immediately available funds at the end of each
quarter at the Lender's Corporate Office. Any amounts not paid when due (at
maturity, by acceleration, or otherwise) shall bear interest thereafter until

Note"). The Lender is hereby authorized by the Borrower to endorse on the
schedule attached to the Note the amount of each Revolving Credit Loan and of
each payment of principal received by the Lender on account of the Revolving
Credit Loans, which endorsement shall, in the absence of manifest error, be
conclusive as to the outstanding balance of the Revolving Credit Loans made by
the Lender; provided, however, that the failure to make such notation with
respect to any Revolving Credit Loan or payment shall not limit or otherwise
affect the obligations of the Borrower under this Agreement or the Revolving
Credit Note.

            SECTION 2.06. Method of Payment. The Borrower shall make each
payment under this Agreement and under the Note not later than 2:00 P.M. (New

when due under this Agreement or under the Note, to charge from time to time
against any account of the Borrower with the Lender any amount so due. Whenever
any payment to be made under this Agreement or under the Note shall be stated to
be due on a Saturday, Sunday, or a public holiday, or the equivalent for banks
generally under the laws of the State of New York, such payment shall be made on

extend credit to any Person for the purpose of purchasing or carrying any such
margin stock or for any purpose which violates, or in inconsistent with,
Regulation X of said Board of Governors.

            SECTION 2.08. Taxes and Other Charges. (a) All principal, interest,
and other amounts payable by Borrower to the Lender with respect to the Loan
shall be paid in full, free and clear of any deductions or withholdings imposed
by Laws. If Borrower is prohibited by any Laws from making such payments free
and clear of deductions or withholdings, the Borrower shall pay all additional
amounts necessary so that the actual amount received by the Lender after such
deductions or withholdings (and after any deductions or withholdings or payment
of additional taxes or charges due as a consequence of the payment of such
additional amount) equals the amount that would have been received by the Lender
if such deductions or withholdings were not required; (b) The Borrower shall pay
directly to the appropriate taxing authority any and all present and future
taxes, levies, stamp and other fees imposed by applicable Laws on or with regard
to any aspect of the Loans and/or any other transactions contemplated by this
Agreement, except taxes imposed on the overall net income or gross receipts of
the Lender, Borrower agrees to indemnify and hold harmless from all loss, cost,
liability, or expense, incurred by the Lender (including reasonable attorneys'
fees and costs) by reason of the delay or failure by Borrower to pay any such
taxes or charges promptly after demand; and Borrower shall reimburse the Lender
upon demand for any such taxes paid by it in connection therewith if the
Borrower does not pay such taxes directly (together with any interest, penalties
and expenses related thereto) (and the Lender shall not be required to obtain a
final determination of the legal validity of such taxes.

$500,000                                                As of November 1, 2004
                                                        New York, New York

            FOR VALUE RECEIVED, the undersigned, Alternative Construction
Company, Inc., a Florida corporation (the "Borrower"), DOES HEREBY PROMISE to
pay to the order of Avante Holding Group, Inc (the "Lender"), at its office at
1900 S. Harbor City Blvd, Suite 315, Melbourne, FL 32901, in lawful money of the
United States and in immediately available funds, the principal amount of Five
Hundred Thousand Dollars ($500,000 or the aggregate unpaid principal amount of
all Revolving Credit Loans (as defined in the Revolving Credit Agreement
hereafter defined) made to the Borrower by the Lender pursuant to the Revolving
Credit Agreement (the "Revolving Credit Loans") hereinafter referred to,
whichever is less, on the Termination Date (as defined in the Revolving Credit
Agreement), and to pay interest (computed on the basis of a year of 360 days
from the date of this Revolving Credit Note) on the unpaid principal amount of
this Revolving Credit Note, in like money, at said office, at a rate per annum
equal to the Prime Rate plus four percent (4%) payable on each Interest Payment
Date. Any amount of principal hereof which is not paid when due (whether at
maturity, by acceleration, or otherwise) shall bear interest thereafter until
paid at a rate which shall be two percent (2%) above the rate which would
otherwise be applicable.

            The Borrower hereby authorizes the Lender to endorse on the Schedule
annexed to this Revolving Credit Note all Revolving Credit Loans made to the
Borrower and all payments of principal amount in respect of such Revolving
Credit Loans, which endorsements shall, in the absence of manifest error, be
conclusive as to the outstanding principal amount of all Revolving Credit Loans;
provided, however, that the failure to make such notation with respect to any
Revolving Credit Loan or payment shall not limit or otherwise affect the
obligations of the Borrower under the Revolving Credit Agreement or this
Revolving Credit Note.

            This Revolving Credit Note is referred to in the Revolving Credit
Agreement dated November 1, 2004, between the Borrower and the Lender (the
"Revolving Credit Agreement"). The Revolving Credit Agreement, among other
things, contains provisions for acceleration of the maturity of this Revolving
Credit Note upon the happening of certain stated events and also for prepayments
on account of the principal of this Revolving Credit Note prior to the maturity
of the Revolving Credit Note upon the terms and conditions specified in the
Revolving Credit Agreement.

<PAGE>

            This Revolving Credit Note shall be governed by the laws of the
State of Florida, provided that, as to the maximum rate of interest which may be
charged or collected, if the laws applicable to the Lender permit it to charge
or collect a higher rate than the laws of the State of Florida then such law
applicable to the Lender shall apply to the Lender under this Revolving Credit
Note.
