$1,500,000                                                        July 10, 2000


         FOR VALUE RECEIVED, the undersigned, TUFCO, L.P., a Delaware limited
partnership (the "Borrower"), hereby promises to pay to the order of First Union
National Bank (the "Bank"), at the Principal Office of the Agent, in lawful
money of the United States of America and in immediately available funds, the
principal amount of ONE MILLION FIVE HUNDRED THOUSAND DOLLARS ($1,500,000) or
such other amount as shall equal the aggregate unpaid principal amount of the
Revolving Loans made by the Bank to the Borrower under the Credit Agreement
referred to below, on the dates and in the principal amounts provided in the
Credit Agreement, and to pay interest on the unpaid principal amount of each
such Revolving Loan, at such office, in like money and funds, for the period
commencing on the date of such Revolving Loan until such Revolving Loan shall be

Agreement.

         The Borrower hereby authorizes the Bank to record in its records the
amount of each Revolving Loan and Type of Accounts established under each
Revolving Loan and all Continuations, Conversions and payments of principal in
respect thereof, which records shall, in the absence of manifest error,
constitute prima facie evidence of the accuracy thereof; provided, however, that
the failure to make such notation with respect to any such Revolving Loan or
payment shall not limit or otherwise affect the obligations of the Borrower
under the Credit Agreement or this Revolving Note.

         This Revolving Note is one of the Revolving Notes referred to in the
Credit Agreement dated as of August 28, 1998, among the Borrower, Tufco
Technologies, Inc., the other banks named therein and Bank, as agent for such
banks (the "Agent"), as amended by that First Amendment to Credit Agreement
dated as of December 18, 1998 and as further amended by that Second Amendment to
Credit Agreement dated as of the date hereof (such Credit Agreement, as the same
may be further amended or otherwise modified from time to time, being referred
to herein as the "Credit Agreement"), and evidences Revolving Loans made by the
Bank thereunder. The Credit Agreement, among other things, contains provisions
for acceleration of the maturity of this Revolving Note upon the happening of
certain stated events and for prepayments of Revolving Loans prior to the
maturity of this Revolving Note upon the terms and conditions specified in the
Credit Agreement. Capitalized terms used in this Revolving Note have the
respective meanings assigned to them in the Credit Agreement.

         This Revolving Note shall be governed by and construed in accordance
with the laws of the State of Texas and the applicable laws of the United States
of America.

         Except for any notices expressly required by the Loan Documents, the
Borrower and each surety, guarantor, endorser and other party ever liable for
payment of any sums of money payable on this Revolving Note jointly and
severally waive notice, presentment, demand for payment, protest, notice of


<PAGE>   8

protest and non-payment or dishonor, notice of acceleration, notice of intent to
accelerate, notice of intent to demand, diligence in collecting, grace and all
other formalities of any kind, and consent to all extensions without notice for
any period or periods of time and partial payments, before or after maturity,
and any impairment of any collateral securing this Revolving Note, all without
prejudice to the holder. The holder shall similarly have the right to deal in
any way, at any time, with one or more of the foregoing parties without notice
to any other party, and to grant any such party any extensions of time for
payment of any of said indebtedness, or to release any such party or to release
or substitute part or all of the collateral securing this Revolving Note, or to
grant any other indulgences or forbearances whatsoever, without notice to any
other party and without in any way affecting the personal liability of any party
hereunder.

         This Revolving Note is in addition to and does not replace that certain
Revolving Note dated August 28, 1998 made by the Borrower in favor of the Bank.
