                             SECURED PROMISSORY NOTE

$4,000,000                                                      October 19, 2000
Term Note C

         FOR VALUE RECEIVED, the undersigned (hereinafter "Borrower"), jointly
and severally, hereby promises to pay to the order of Ableco Finance LLC, a
Delaware limited liability company (hereinafter "Lender"), such payment to be
made to Administrative Agent for the account of 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
$4,000,000, together with interest from and after the date hereof:

         Interest shall accrue on the unpaid principal balance outstanding of
the Term Loan C evidenced by this Note at the greater of (y) 12.00% per annum,
and (z) a fluctuating rate per annum equal to the Base Rate plus 2.50%. The rate
of interest set forth in the foregoing clause (z) shall increase or decrease by
an amount equal to any increase or decrease in the Base Rate, effective as of
the opening of business on the day that any such change in the Base Rate occurs.

         This Secured Promissory Note (the "Note") is one of a series of the
Term Notes C referred to in, and is issued pursuant to, that certain Amended and
Restated Loan and Security Agreement among Borrower, Lender, certain other
financial institutions party thereto, Congress Financial Corporation (Florida),
as Administrative Agent thereunder, and Ableco Finance LLC, a Delaware limited
liability company, as Collateral Agent thereunder, dated as of June 29, 1999
(hereinafter, as amended from time to time, the "Loan Agreement"), and is
entitled to all of the benefits and security of the Loan Agreement. All of the
terms, covenants and conditions of the Loan Agreement and the other Loan
Documents are hereby made a part of this Note and are deemed incorporated herein
in full. All capitalized terms used herein, unless otherwise specifically
defined in this Note, shall have the meanings ascribed to them in the Loan
Agreement.

         All interest shall be computed in the manner provided in Section 2 of
the Loan Agreement. Upon the occurrence and during the continuation of an Event
of Default, the interest rate provided herein shall be increased in accordance
with the provisions of Section 2.1.2 of the Loan Agreement.

         For so long as no Event of Default shall have occurred and be
continuing the principal amount and accrued interest of this Note shall be due
and payable on the dates and in the manner hereinafter set forth:

<PAGE>   20

                  (a) Interest shall be due and payable monthly, in arrears, on
         the first day of each month, commencing on November 1, 2000, and
         continuing until such time as the full principal balance hereof,
         together with all other amounts owing hereunder, shall have been paid
         in full; and

                  (b) The entire remaining principal amount hereof then
         outstanding, together with any and all other amounts due hereunder,
         shall be due and payable on September 30, 2003.

Notwithstanding the foregoing, the entire unpaid principal balance hereof and
accrued interest thereon shall be due and payable immediately upon any
termination of the Loan Agreement pursuant to Section 4 thereof.

         This Note shall be subject to mandatory prepayment in accordance with
the provisions of Section 3.3 of the Loan Agreement. Borrower may also terminate
the Loan Agreement and, in connection with such termination, prepay this Note in
the manner provided in Section 4 of the Loan Agreement.

         Upon the occurrence and during the continuance of an Event of Default,
Lender shall have all of the rights and remedies set forth in Section 10 of the
Loan Agreement.

         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 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 provision or remaining 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. Lender, at its
option, may enforce its rights against any collateral securing this Note without
enforcing its rights against Borrower or any other property or indebtedness due
or to become due to Borrower. Borrower agrees that, without releasing or
impairing Borrower's liability hereunder, Lender (or its agent) may at any time
release, surrender, substitute or exchange any collateral securing this Note and
may at any time release any party primarily or secondarily liable for the
indebtedness evidenced by this Note.

         Each Person composing Borrower hereby waives any defenses such Person
might have based upon suretyship or impairment of collateral, such waiver being
intended as a waiver contemplated by Section 3-605 of the Code.
