PROMISSORY NOTE NO. 006

FOR VALUE RECEIVED, WINCUP HOLDINGS, INC. (the “Borrower”) hereby promises to pay to the order of MERRILL LYNCH CAPITAL, A DIVISION OF MERRILL LYNCH BUSINESS FINANCIAL SERVICES INC. (“Lender”) in lawful money of the United States of America and in immediately available funds the principal amount of $1,229,054.96, or so much thereof as may then be advanced and outstanding hereunder (the total of all such advances outstanding at the time of determination being hereinafter referred to as the “Principal Sum”), together with interest on the Principal Sum outstanding from time to time at the Interest Rate. Interest shall be computed on the basis of a 360-day year, 30 day month.

As used herein, “Interest Rate” shall mean 7.6655 percent per annum.

This Note dated as of November 12^th, 2004 is issued pursuant to a Loan and Security Agreement dated as of June 24^th, 2004 (the “Agreement”), between the Borrower and Lender. Capitalized terms used herein without definition shall have the meaning given them in the Agreement.

Principal and interest due hereunder shall be payable as follows:

(a) Interest only shall be payable on the Principal Sum for the period from the date of execution of this Note to December 1st, 2004; payable on December 1^st, 2004; at the Interest Rate.

(b) Sixty (60) consecutive monthly installments of principal and interest, each in the principal amount of $24,724.51 payable in arrears on the first day of each calendar month during the term hereof with the first payment due January 1^st, 2005.

(c) Interest on any overdue payment shall be due and payable at the rate of the Interest Rate plus two (2) percent per annum until paid (the “Late Charge Rate”).

This Note may not be prepaid prior to December 1^st, 2005. Thereafter, this Note may be prepaid by Borrower in whole on an installment due date, after giving thirty (30) days’ prior written notice to Lender of its intention to make such prepayment, by paying, in addition to such prepayment, all interest accrued to the date of such payment accompanied by a Prepayment Premium. The Prepayment Premium shall be calculated as the following specified percentage of the Principal Sum:

LOAN AND SECURITY AGREEMENT#: 0504010-006

In the event of the declaration by Lender of a Default under the Agreement, then this Note shall be in default and the balance of the principal sum then due hereunder, together with all accrued interest thereon, immediately shall become due and payable without further notice, such further notice being expressly waived, and the Borrower shall be liable to the holder hereof for reasonable attorney’s fees and costs of suit.

The Borrower waives presentment for payment, demand, notice of demand, notice of nonpayment or dishonor, protest and notice of protest of this Note, and all other notices in connection with the delivery, acceptance, performance, default or enforcement of the payment of this Note.

The remedies of Lender as provided herein and in the Agreement shall be cumulative and concurrent and may be pursued singly, successively or together, at the sole discretion of Lender, and may be exercised as often as occasion therefor shall occur; and the failure to exercise any such right or remedy shall in no event be construed as a waiver or release thereof.

It is the intention of the parties hereto to comply with the applicable usury laws. Accordingly, it is agreed that, notwithstanding any provisions to the contrary in this Note or the Agreement, in no event shall this Note or the Agreement require the payment or permit the collection of interest in excess of the maximum amount permitted by applicable law. If any such excess interest is contracted for, charged or received under this Note or the Agreement, or in the event that all of the principal balance shall be prepaid, so that under any of such circumstances the amount of interest contracted for, charged or received under this Note or the Agreement on the principal balance shall exceed the maximum amount of interest permitted by applicable law, then in such event: (a) the provisions of this paragraph shall govern and control, (b) neither the Borrower nor any other person or entity now or hereafter liable for the payment hereof shall be obligated to pay the amount of such interest to the extent that it is in excess of the maximum amount of interest permitted by applicable law, (c) any such excess which may have been collected shall either be applied as a credit against the then unpaid principal balance or refunded to the Borrower, at the option of Lender, and (d) the effective rate of interest shall be automatically reduced to the maximum lawful contract rate allowed under the applicable law as now or hereafter construed by the courts having jurisdiction thereof. It is further agreed that, without limitation of the foregoing, all calculations of the rate of interest contracted for, charged or received under this Note or the Agreement which are made for the purpose of determining whether such rate exceeds the maximum lawful contract rate, shall be made, to the extent permitted by applicable law, by amortizing, prorating, allocating and spreading in equal parts during the period of the full stated term of the Indebtedness evidenced hereby, all interest at any time contracted for, charged or received from the Borrower or otherwise by Lender in connection with such Obligations; provided, however, that if any applicable state law is amended or the law of the United States of America preempts any applicable state law, so that it becomes lawful for Lender to receive a greater interest per annum rate than is presently allowed by law, the Borrower agrees that, on the effective date of such amendment or preemption, as the case may be, the lawful maximum hereunder shall be increased to the maximum interest rate per annum allowed by the amended state law or the law of the United States of America (but not in excess of the Interest Rate provided for herein).
