                          SECTION 1: CREDIT COMMITMENTS

Section 1.1.  Revolving Credit Commitment

1.1.1    Amount. Bank One hereby agrees to lend the Borrowers (this, and all
         other capitalized terms used herein, are defined in Section 7) the
         maximum aggregate amount of Fifteen Million Dollars ($15,000,000) in
         the form of revolving credit loans under the Revolving Credit Notes in
         the maximum collective amount of Fifteen Million Dollars ($15,000,000),
         minus the drawn or undrawn principal amount of any letter of credit or
         other independent undertaking issued by Bank One for the account of the
         Borrowers (the "Credit Commitment").

1.1.2    Disbursements. The Companies shall execute and deliver to Bank One the
         amended and restated revolving credit note in the form of Exhibit A-1
         attached hereto (the "$13,000,000 Revolving Credit Note") and the
         Borrowers shall execute and deliver to Bank One the revolving credit
         note in the form of Exhibit A-2 attached hereto (the "$2,000,000
         Revolving Credit Note" and, collectively with the $13,000,000 Revolving
         Credit Note, the "Revolving Credit Notes"). Bank One may make
         disbursements to the Borrowers from time to time in principal amounts
         at any one time outstanding up to an amount that equals the lesser of
         (a) the Credit Commitment or (b) the Borrowing Base. Subject to the
         terms and conditions of the Agreement, the Borrowers may borrow, repay
         and reborrow loans under the Revolving Credit Notes from Bank One at
         any time or from time to time, without penalty, from the date of the
         Agreement until the earlier of (a) July 1, 2001 or (b) the date amounts

                                       1

         Notes become due and payable, whether through acceleration or any other
         cause. The Revolving Credit Notes mature and become due and payable on
         July 1, 2001.

1.1.3    Use of Proceeds. The proceeds of the Revolving Credit Notes shall be
         used in their entirety for working capital needs and to fund
         installment sales contracts from selected customers.

1.1.4    Maturity and Interest Rate. The Revolving Credit Notes will mature on
         July 1, 2001 and shall bear interest prior to maturity at an interest
         rate to be elected by the Companies or the Borrowers from either
         subparagraph (a) or subparagraph (b), as adjusted pursuant to
         subparagraph (c).

         (a)      Prime Rate. A rate equal to the Prime Rate. Interest payable
                  under this option shall be paid by Companies or the Borrowers
                  on the last day of any calendar quarter in which the Companies
                  or the Borrowers have elected the Prime Rate option to be in
                  effect. The rate of interest shall be adjusted to reflect the
                  change in the Prime Rate effective immediately following any
                  change in the Prime Rate; or

         (b)      LIBOR Rate. A rate ("LIBOR Rate") equal to two hundred (200)
                  basis points in excess of the rate of interest at which Bank
                  One is offered U.S. dollar deposits in the London Eurodollar
                  Interbank Market ("LIBOR") in an amount equal to the principal
                  amount of such Loan for the period of thirty (30) days, sixty
                  (60) days, ninety (90) days, one hundred twenty (120) days,
                  one hundred eighty (180) days or one year (the "Benchmark
                  Rate") (to be elected at the option of the Companies or the
                  Borrowers) in effect, and as quoted by Bank One by telephone
                  to, and accepted by, the Companies or the Borrowers prior to
                  2:00 P.M., Ohio time, commencing on the day immediately after
                  the election is made. In addition, the Companies or the
                  Borrowers shall pay any LIBOR reserve costs in effect which
                  would be incurred by Bank One with respect to LIBOR borrowings
                  hereunder. Interest payable at the LIBOR Rate shall be paid on
                  the earlier of (a) the last day of any calendar quarter in
                  which the Companies or the Borrowers have elected the LIBOR
                  Rate option to be in effect or (b) upon the maturity of the
                  LIBOR contract. In the event the Companies or the Borrowers
                  fail prior to or on the last day of the period so elected to
                  elect a subsequent such period, interest shall automatically
                  accrue thereafter at the Prime Rate option as herein set
                  forth. The Companies may not elect an interest rate period
                  expiring after July 1, 2001.

         (c)      Performance Based Pricing. If, at the end of any calendar
                  quarter, the Leverage Ratio is greater than or equal to 1.5 to
                  1.0, the interest rate for the succeeding calendar quarter
                  shall be adjusted to, as appropriate, either the Prime Rate or
                  two hundred (200) basis points in excess of the Benchmark
                  Rate. If, at the end of any calendar quarter, the Leverage
                  Ratio is less than 1.5 to 1.0 and equal to or greater than 1.0
                  to 1.0, the interest rate for the succeeding calendar quarter
                  shall be adjusted, as appropriate, to either the Prime Rate
                  minus twelve and one-half (12.5) basis points or one hundred
                  seventy-five (175) basis points in excess of the

                                       2
<PAGE>   3
                  Benchmark Rate. If, at the end of any calendar quarter, the
                  Leverage Ratio is less than 1.0 to 1.0, the interest rate for
                  the succeeding calendar quarter shall be adjusted to, as
                  appropriate, either the Prime Rate minus twenty-five (25)
                  basis points or one hundred fifty (150) basis points in excess
                  of the Benchmark Rate. For the calendar quarter commencing
                  April 1, 2000, the interest rate shall be either the Prime
                  Rate or 200 basis points in excess of the Benchmark Rate.

1.1.5    As consideration for the Credit Commitment, the Companies shall pay
         Bank One a facility fee on the daily unused portion of the Credit
         Commitment at a rate equal to the Applicable Rate (as defined below),
         per annum starting with the date this Agreement becomes effective, said
         fee to be computed on the basis of the actual number of days elapsed
         over a year of 360 days and to be payable quarterly commencing on June
         30, 2000. The "Applicable Rate" for any calendar quarter means (a) one
         quarter percent (0.25%) if, at the end of such calendar quarter, the
         Leverage Ratio is greater than or equal to 1. 0 to 1.0, or (b)
         one-eighth percent (0.125%) if, at the end of such calendar quarter,
         the Leverage Ratio is less than 1.0 to 1.0. The Companies shall be
         entitled to cancel the Credit Commitment in whole or in part at any
         time by payment in full of the Revolving Credit Notes accompanied by
         notice to Bank One of cancellation, which notice shall be irrevocable.

Section 1.2.  Provisions Applicable to All Notes.

1.2.1    The Revolving Credit Notes shall hereinafter sometimes be collectively
         referred to hereunder as the "Notes".

1.2.2.   Outstanding loans that bear the Prime Rate may be prepaid in whole at
         any time or in part from time to time in an amount which is a whole
         multiple of U.S. dollars (or such lesser amount as constitutes the
         entire amount outstanding) without premium or penalty. Outstanding
         loans that bear the LIBOR Rate may only be prepaid as provided for in
         this Section. The Companies or the Borrowers may not prepay or reduce
         LIBOR Rate loans unless the Companies or the Borrower first pay all
         fees, costs, penalties and premiums incurred by Bank One because of
         such payment or reduction. Repayment of a Loan at the LIBOR Rate upon
         the maturity of the LIBOR contract thereof shall not cause such LIBOR
         prepayment of the Revolving Credit Notes and no prepayment of the
         Revolving Credit Notes shall affect the Companies or the Borrowers'
         right to reborrow from Bank One before July 1, 2001.

1.2.3.   After any Note becomes due and payable, whether at maturity, by
         acceleration or otherwise, the interest rate on the outstanding
         principal sum and accrued interest will be the Prime Rate plus two
         hundred (200) basis points per annum. Without any limitation upon Bank
         One's remedies upon an Event of Default, Bank One shall have the right
         to assess a late payment fee in the amount of the greater of $50.00 or
         5% of the scheduled payment if a payment is at least 12 days late.

                                       3
<PAGE>   4
1.2.4    Interest shall be calculated on the basis of the actual number of days
         elapsed divided by a year of 360 days.

1.2.5.   Upon the occurrence and during the continuation of any Event of
         Default, Bank One shall have the right to setoff against all
         obligations of the Companies or the Borrowers to Bank One hereunder and
         under the Notes, whether matured or unmatured, all funds of the
         Companies or the Borrowers on deposit in accounts with Bank One except
         for funds deposited or accounts maintained for the payment of taxes,
         payroll and employee contributions and any other funds or accounts in
         which the Companies or the Borrowers do not have a beneficial interest.

1.2.6    The Companies and the Borrowers shall make all payments on account of
         principal of, and interest on, the Notes, in immediately available
         funds to Bank One at its Main Office, Corporate Banking Division, Bank
         One, NA, 100 East Broad Street, Columbus, Ohio 43271-0170 as such
         payments become due and payable in accordance with the terms hereof and
         of the Notes.

Section 1.3. Waiver Fee. The Companies shall pay Bank One a waiver fee of
$25,000 upon the execution hereof.

                  shall continue unstayed and in effect for any period of
                  forty-five (45) days;

         then upon the occurrence of any such Event of Default specified in

         the events specified in subdivision J of this Section, Bank One's
         commitment to lend shall terminate and all amounts due under the Notes
         shall become immediately due and payable. The Notes shall then become
         immediately due and payable without presentment, demand, protest, or
         notice of any kind, all of which are hereby expressly waived, anything
         contained herein or in the Notes to the contrary notwithstanding. It is
         understood that the remedies of Bank One hereunder shall be cumulative
         in nature rather than exclusive and that the failure of Bank One to
         exercise its rights upon an Event of Default by the Companies hereunder
         shall not be deemed to be a waiver by Bank One of that Event of Default
         or any of its rights hereunder. BANK ONE SHALL NOT BE REQUIRED, AS A
         CONDITION TO THE LIABILITY OF ANY OF THE COMPANIES, TO RESORT TO,
         ENFORCE OR EXHAUST ANY OF ITS REMEDIES AGAINST ANY OTHER OF THE
         COMPANIES OR TO RESORT TO, ENFORCE OR EXHAUST ANY OF ITS REMEDIES
         AGAINST ANY PROPERTY WHICH MAY AT ANY TIME BE GIVEN OR HELD AS SECURITY
         FOR THE NOTES OR UPON WHICH BANK ONE OBTAINS A LIEN FOR REPAYMENT OF
         THE NOTES. When any indebtedness of the Companies to Bank One becomes
         due, by acceleration or otherwise, Bank One shall have the right,
         without notice to the Companies, any party claiming under the
         Companies, or any other party, such notice being hereby expressly
         waived, and without regard to the adequacy or value of the collateral
         or the solvency or insolvency of the Companies, to the appointment of a
         receiver by a court of competent jurisdiction chosen solely by Bank
         One, upon application at any time, whether prior to or after a judgment
         has been obtained against Companies, to take possession of the business
         of the Companies together with its books and records, to maintain or to
         liquidate said business, to collect the proceeds of the collateral and
         apply the net proceeds to any indebtedness of the Companies to Bank
         One. The Companies consents to jurisdiction and venue for the
         appointment of such receiver by such court and agrees that any receiver
         so appointed may take possession of the business of the Companies,
         together with the collateral in any other jurisdiction in which the
         collateral may be located.
