         1. PROMISE TO PAY. The undersigned corporations (collectively,
"Borrower"), for value received, promise to pay to the order of SOUTHTRUST BANK,
NATIONAL ASSOCIATION ("Bank"), 420 North 20th Street, Birmingham, Alabama 35203,
or at such other place as the holder of this Note designates in writing to
Borrower, the principal amount of TWENTY THREE MILLION AND NO/100THS DOLLARS
(U.S. $23,000,000.00), or, if less, the aggregate unpaid Revolving Loan (as
defined in the Loan Agreement described below) made to Borrower pursuant to the
Loan and Security Agreement dated June 2, 1999, as amended by that Amendment No.
1 to the Loan and Security Agreement dated the same date of this Note, between
Bank and Borrower (the "Loan Agreement"). Borrower shall pay interest and
principal on this Note from the date of this Note until paid in full at the
times and interest rates set forth for the Revolving Loan in the Loan Agreement.
THIS NOTE SUPERSEDES AND REPLACES THE REVOLVING LOAN PROMISSORY NOTE DATED JUNE
2, 1999, EXECUTED BY BORROWER.

         2. APPLICATION AND FORM OF PAYMENTS. Payments will be applied first to
accrued interest and then to principal, and all interest on this Note will be
computed on the basis of the actual number of days elapsed over a 360-day year.
Payments of interest and principal must be made in such coin or currency of the
United States of America as at the time of payment is legal tender for the
payment of public and private debts. Payments received after 2:00 p.m. Eastern
Standard Time will be treated as being received on the next banking day.

         3. DEFAULT; REMEDIES; PAYMENT OF COSTS. This Note is executed pursuant
to the Loan Agreement and is secured by a deed of trust, liens and security
interests granted by Borrower to Bank and further described in the Loan
Agreement. The provisions of the Loan Agreement are incorporated by reference in
this Note, and reference is made to the Loan Agreement for a description of the
relative rights and obligations of Borrower and Bank concerning this Note,
including events of default, acceleration of maturity in the event of default,
and payment by Borrower of all costs and expenses incurred by the holder of this
Note in enforcing or collecting this
<PAGE>

Note. The terms used in the Loan Agreement are used in this Note with the same
meaning set forth in the Loan Agreement.

         4. WAIVER AND CONSENTS. Borrower and every other person liable at any
time for payment of this Note waives presentment, protest, notice of protest,
and notice of dishonor. Borrower expressly consents to all extensions and
renewals of this Note (as a whole or in part) and all delays in time of payment
or other performance under this Note that the holder of this Note grants at any
time and from time to time, without limitation and without any notice to or
further consent of Borrower. Borrower agrees that its obligations under this
Note are independent of the obligations of any other person or entity that now
or later is obligated to pay this Note. Borrower also agrees that Bank may
release any security for or other obligor of this Note or waive, extend, alter,
amend, or modify the Note or otherwise take any action that varies the risk of
Borrower without releasing or discharging Borrower from its obligation to repay
this Note.

         5. VENUE AND WAIVER OF JURY TRIAL. Borrower further agrees that venue
for each action, suit, or other legal proceeding arising under or relating to
this Note or any agreement securing or related to this Note shall be as set
forth in the Loan Agreement. BORROWER AND BANK KNOWINGLY, VOLUNTARILY, AND
INTENTIONALLY WAIVE ALL RIGHTS TO A JURY TRIAL IN ANY LAWSUIT, PROCEEDING,
COUNTERCLAIM, OR OTHER LITIGATION ARISING UNDER OR RELATING TO THIS NOTE OR ANY
AGREEMENT SECURING OR RELATING TO THIS NOTE. BORROWER AND BANK HAVE FULLY
DISCUSSED THIS PROVISION AND AGREE THAT THIS WAIVER IS SUBJECT TO NO EXCEPTIONS
AND WAS A MATERIAL INDUCEMENT FOR BANK TO MAKE THE LOANS EVIDENCED BY THIS NOTE
TO BORROWER.

         6. MISCELLANEOUS. The headings preceding the text of the sections of
this Note have been inserted solely for convenience of reference and do not
limit or affect the meaning, interpretation, or effect of this Note or the
