                                   TERM NOTE

$8,750,000.00                                         Dated as of July 31, 1997
                                                                Cleveland, Ohio


         FOR VALUE RECEIVED, the undersigned, jointly and severally if more
than one, promise to pay to the order of THE HUNTINGTON NATIONAL BANK
(hereinafter called the "Bank", which term shall include any holder hereof), at
such place as the Bank may designate or, in the absence of such designation, at
any of the Bank's offices, the sum of Eight Million Seven Hundred Fifty
Thousand and No/100 Dollars ($8,750,000.00) (hereinafter called the "Principal
Sum"), together with interest as hereinafter provided. The undersigned promise
to pay the Principal Sum and the interest thereon at the time(s) and in the
manner(s) hereinafter provided in this note (this "Note").


         This Note is executed and the advances contemplated hereunder are to
be made pursuant to a Loan and Security Agreement by and between the
undersigned and the Bank (hereinafter called the "Loan Agreement") dated as of
July 31, 1997, and all the covenants, representations, agreements, terms and
conditions contained therein, including but not limited to additional
conditions of default, are incorporated herein as if fully rewritten.

INTEREST

         Interest will accrue on the unpaid balance of the Principal Sum at
the applicable interest rate set forth in the Loan Agreement. Interest shall be
payable quarterly and at such other times as specified in the Loan Agreement.


         Upon the occurrence and during, the continuance of an "Event of
Default" pursuant to the Loan Agreement, interest will accrue on the unpaid
balance of the Principal Sum and unpaid interest, if any, until paid, at a
variable rate of interest per annum, which shall change in the manner set forth
below, equal to five percentage points (5%) in excess of the Prime Commercial
Rate.

         All interest shall be calculated on the basis of a 360 day year for
the actual number of days the Principal Sum or any part thereof remains unpaid.

         As used herein, Prime Commercial Rate shall mean the rate established
by the Bank from time to time based on its consideration of economic, money
market, business and competitive factors, and it is not necessarily the Bank's
most favored rate. Subject to any maximum or minimum interest rate limitation
specified herein or by applicable law, any variable rate of interest on the
obligation evidenced hereby shall change automatically without notice to the
undersigned immediately with each change in the Prime Commercial Rate.

MANNER OF PAYMENT

         The Principal Sum shall be due and payable in twenty-eight (28)
consecutive quarterly installments, beginning on September 30, 1997, and
continuing on the last day of each calendar quarter thereafter, and at maturity
whether by demand, acceleration, or otherwise. Each installment of the
Principal Sum shall be in the amount of Three Hundred Twelve Thousand Five
Hundred and No/100 Dollars ($312,500.00), plus a final installment of the
remaining Principal Sum which shall be due and payable on June 30, 2004. The
undersigned shall also pay annual Mandatory Prepayments pursuant to Section 2
of the Loan Agreement. Regular payments made by the undersigned with respect to
the indebtedness evidenced hereby shall be applied first to accrued interest
then due and then to the Principal Sum. Optional and Mandatory Prepayments made
by the undersigned with respect to the indebtedness evidenced hereby shall be
applied first to accrued interest then due and then to the Principal Sum in the
inverse order of installments due hereunder without relieving the undersigned
from continuing to make regular payments as set forth herein and in the Loan
Agreement.

PREPAYMENT

         Prepayment of all or any portion of the Principal Sum may be subject
to a prepayment premium as set forth in the Loan Agreement.

LATE CHARGE

         Any installment or other payment not made within 10 days of the date
such payment or installment is due shall be subject to a late charge equal to
the lesser of 5% of the amount of the installment or payment, or $250.00.

SECURITY

         This Note is secured by the security interest in the Collateral (as
defined in the Loan Agreement) granted by the undesigned pursuant to the terms
and conditions of the Loan Agreement. The rights of the Bank under this Note
shall be cumulative and in addition to any and all rights of the Bank under the
Loan Agreement or otherwise.

DEFAULT

         Upon the occurrence and continuance of an "Event of Default" under the
Loan Agreement, the Bank may, at its option, without notice or demand,
accelerate the maturity of the obligations evidenced hereby, which obligations
shall become immediately due and payable. In the event the Bank shall institute
any action for the enforcement or collection of the obligations evidenced
hereby, the undersigned agree to pay all costs and expenses of such action,
including reasonable attorneys' fees, to the extent permitted by law.
